Income ETF Investment Objective The State Street Blackstone High Income ETF (the “Fund”) seeks to provide risk-adjusted total return and high current income. Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0070 0 0.0000 0.0070 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 72 224 390 871 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 172% of the average value of its portfolio. 1.72 The Fund's Principal Investment Strategy Under normal circumstances, Blackstone Liquid Credit Strategies LLC (the “Sub-Adviser”) will invest the Fund's assets primarily in U.S. dollar denominated high yield debt securities. High yield debt securities include high yield corporate bonds, senior loans and debt tranches of U.S. collateralized loan obligations (“CLOs”). The Fund will invest in CLOs to gain indirect exposure to senior loans. High yield debt securities (commonly known as “junk” bonds) are securities that are rated at the time of investment BB+ or lower by S&P Global Ratings or Fitch Ratings Inc., Ba1 or lower by Moody's Investors Service, Inc. or equivalent ratings by another nationally recognized statistical rating organization, or if unrated, determined by the Sub-Adviser to be of comparable quality. The Fund may invest in debt securities of any maturity. The Fund may invest up to 100% of its net assets in either high yield corporate bonds or senior loans. The Fund's investments in CLOs will not exceed 15% of its net assets (measured at the time of investment). In pursuing its investment objective, the Fund seeks to outperform a composite benchmark comprising 50% high yield bonds and 50% high yield senior loans with less volatility than the general bond and loan markets over full market cycles. The high yield bond portion of the composite benchmark is represented by the ICE BofA US High Yield Constrained Index, and the senior loan portion is represented by the Morningstar LSTA US Leveraged Loan Index.The Fund seeks to maximize performance while minimizing risk (“risk-adjusted returns”) by investing in high yield corporate bonds, senior loans, and debt tranches of U.S. CLOs using a top-down asset allocation approach coupled with bottom-up security selection. The top-down asset allocation approach evaluates macroeconomic, technical, fundamental, and relative value factors to determine allocation weights among the asset classes that the Sub-Adviser believes will result in the best long-term risk-adjusted returns compared to the composite benchmark. The bottom-up security selection process relies on fundamental credit research to dictate security selection within each asset class, seeking to capture credit risk premium by exploiting potential mispricing at the individual security level. When constructing the Fund's portfolio, the Sub-Adviser manages the Fund's asset class, industry, ratings, liquidity and issuer exposures in an effort to optimize the Fund's risk-adjusted returns. The Fund's investment strategy may result in a high portfolio turnover rate.High Yield Corporate BondsWith respect to the high yield corporate bond portion of the Fund's portfolio, the Sub-Adviser applies a systematic approach to security selection and portfolio construction. This approach focuses on the credit risk of companies issuing the corporate bonds (i.e., the risk of loss due to the uncertainty in a debtor's ability to meet its financial obligations). Under normal circumstances, the Sub-Adviser utilizes a proprietary model (the “Model”) that incorporates data including but not limited to fundamental balance-sheet information, real-time information embedded in equity and options markets, and a database of historical defaults. The Model seeks to identify the most liquid, positively mispriced credit issues, while minimizing exposure to systematic credit risks (e.g., macroeconomic risks such as interest rate and currency fluctuations, market volatility, and industry or sector risk). The Sub-Adviser uses a variety of risk-management tools to produce risk measures for investments that are monitored in “real-time,” providing potential early-warning capabilities. Using information provided by the Model, the Sub-Adviser seeks to construct a high yield corporate bond portfolio that delivers excess returns compared to the ICE BofA US High Yield Constrained Index. The Sub-Adviser also seeks to actively diversify exposure in an attempt to mitigate risk specific to individual issuers or sectors in the Fund's high yield corporate bond portfolio, and seeks to generate returns through its integration of technology, infrastructure, ongoing research, and credit expertise. Senior Loans and CLOsWith respect to the senior loan portion of the Fund's portfolio, the Sub-Adviser seeks to construct a portfolio of senior loans and CLOs that provide exposure to senior loans utilizing a traditional bottom-up discretionary approach to credit selection that relies on fundamental credit analysis in an effort to minimize the loss of the Fund's capital. The Fund invests predominantly in senior loans that are made to businesses operating in North America, but may also invest in senior loans made to businesses operating outside of North America. The Fund may invest in senior loans directly, either from the borrower as part of a primary issuance or in the secondary market through assignments of portions of senior loans from third parties, or participations in senior loans, which are contractual relationships with an existing lender in a loan facility whereby the Fund purchases the right to receive principal and interest payments on a loan but the existing lender remains the record holder of the loan. Under normal market conditions, it is expected that the Fund's senior loan investments will maintain an average interest rate duration of less than 90 days. Loan interest rate duration is based on the actual remaining time until the applicable reference rate is reset for each individual loan. In addition, when making investments, the Sub-Adviser seeks to maintain appropriate liquidity and price transparency for the Fund. The Sub-Adviser expects to invest in senior loans, either directly or indirectly through CLOs, possessing the following attributes, which it believes will help generate higher risk-adjusted total returns:Leading, defensible market positions. The Sub-Adviser intends to invest in senior loans made to companies that it believes have developed strong positions within their respective markets and exhibit the potential to maintain sufficient cash flows and profitability to service their obligations in a range of economic environments. The Sub-Adviser will seek companies that it believes possess advantages in scale, scope, customer loyalty, product pricing, or product quality versus their competitors, thereby minimizing business risk and protecting profitability.Investing in companies with positive cash flow. The Sub-Adviser intends to invest in senior loans made primarily to established companies which have demonstrated a record of profitability and cash flows over several economic cycles. The Sub-Adviser believes such companies are well-positioned to maintain consistent cash flow to service and repay their obligations and maintain growth in their businesses or market share. The Sub-Adviser does not intend to invest primarily in start-up companies, companies in turnaround situations or companies with speculative business plans.Proven management teams. The Sub-Adviser intends to focus on investments in senior loans made to companies that have experienced management teams with established track records of success. The Sub-Adviser will typically require companies to have in place proper incentives to align management's goals with the Fund's goals.Private equity sponsorship. The Sub-Adviser may seek to invest in senior loans made to issuers sponsored by what it believes to be high-quality private equity firms. The Sub-Adviser believes that a private equity sponsor's willingness to invest significant sums of equity capital into a company is an implicit endorsement of the quality of the investment. Further, private equity sponsors of companies with significant investments at risk have the ability and a strong incentive to contribute additional capital in difficult economic times should operational issues arise.Diversification, concentration and reliance on other lenders. The Sub-Adviser will seek to invest broadly among companies and industries, thereby potentially reducing the risk of a downturn in any one company or industry having a disproportionate impact on the value of the Fund's portfolio. While the Fund looks to the underlying borrower of a bank loan, rather than the bank originating the loan, for purposes of determining the industry concentration of investments, it is possible that under a different interpretation the Fund may be deemed to concentrate its investments in the financial services industries. Loans, and the collateral securing them, are typically monitored by agents for the lenders, which may be the originating bank or banks. The Fund may be affected by the creditworthiness of the agent bank and other intermediate participants in a senior loan, in addition to the borrower, since rights that may exist under the loan against the borrower if the borrower defaults are typically asserted by or through the agent bank or intermediate participant. Agents are typically large commercial banks, although for senior loans that are not broadly syndicated they can also include thrift institutions, insurance companies or finance companies (or their affiliates). Such companies may be especially susceptible to the effects of changes in interest rates resulting from changes in U.S. or foreign fiscal or monetary policies, governmental regulations affecting capital raising activities or other economic or market fluctuations.Other InvestmentsIn seeking to achieve risk-adjusted returns, the Fund may also invest in bonds and CLOs rated investment grade as measured at the time of investment. The Fund may also invest in US Treasuries and Notes, and Federal Agency issued securities for cash management purposes. The Fund may also invest in repurchase agreements and may enter into reverse repurchase agreements to reduce cash drag. The Fund may invest in derivatives including futures and forward contracts, and swaps (including total return swaps, and interest rate and credit default swaps) to manage yield, interest rate exposure (also known as duration), weighted average maturity, and exposure to credit quality. In addition, the Fund may use government bond futures for hedging purposes. The Fund may also invest in exchange traded funds (“ETFs”) as a way to gain exposure to certain asset classes and/or securities that are consistent with the principal investment strategy of the Fund. The Fund may invest in certain ETFs that pay fees to the Adviser and its affiliates for management, marketing or other services.Sale of Fund InvestmentsIf circumstances cause the Sub-Adviser to determine there is a likelihood the value of an existing investment will decline over time, the Fund may, if the Sub-Adviser believes that circumstances require, exit the investment. The circumstances giving rise to the Sub-Adviser's determination may, but will not necessarily, coincide with a downgrade of a senior loan, high yield corporate bond or other security's credit rating. High yield debt securities include high yield corporate bonds, senior loans and debt tranches of U.S. collateralized loan obligations (“CLOs”). The Fund will invest in CLOs to gain indirect exposure to senior loans. High yield debt securities (commonly known as “junk” bonds) are securities that are rated at the time of investment BB+ or lower by S&P Global Ratings or Fitch Ratings Inc., Ba1 or lower by Moody's Investors Service, Inc. or equivalent ratings by another nationally recognized statistical rating organization, or if unrated, determined by the Sub-Adviser to be of comparable quality. The Fund seeks to maximize performance while minimizing risk (“risk-adjusted returns”) by investing in high yield corporate bonds, senior loans, and debt tranches of U.S. CLOs using a top-down asset allocation approach coupled with bottom-up security selection. The top-down asset allocation approach evaluates macroeconomic, technical, fundamental, and relative value factors to determine allocation weights among the asset classes that the Sub-Adviser believes will result in the best long-term risk-adjusted returns compared to the composite benchmark. The bottom-up security selection process relies on fundamental credit research to dictate security selection within each asset class, seeking to capture credit risk premium by exploiting potential mispricing at the individual security level. As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Senior Loan Risk: Investments in senior loans are subject to credit risk and general investment risk. Credit risk refers to the possibility that the borrower of a senior loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a senior loan will result in a reduction in the value of the senior loan and consequently a reduction in the value of the Fund's investments and a potential decrease in the net asset value (“NAV”) of the Fund. Senior loans are also subject to the risk that the value of the collateral securing a senior loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. In addition, the Fund's access to the collateral may be limited by bankruptcy or other insolvency laws. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some senior loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the senior loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund, such as invalidation of senior loans or causing interest previously paid to be refunded to the borrower. Senior loans are also subject to high yield securities risks and liquidity risks described above. In addition, bank loans may be subject to extended settlement periods, which may impair the Fund's ability to sell or realize the full value of its loans in the event of a need to liquidate such loans in a compressed period of time. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Credit Risk: Credit risk is the risk that an issuer or counterparty will fail to pay its obligations to the Fund when they are due. As a result, the Fund's income might be reduced, the value of the Fund's investment might fall, and/or the Fund could lose the entire amount of its investment. Changes in the financial condition of an issuer or counterparty, changes in specific economic, social or political conditions that affect a particular type of security or other instrument or an issuer, and changes in economic, social or political conditions generally can increase the risk of default by an issuer or counterparty, which can affect a security's or other instrument's credit quality or value and an issuer's or counterparty's ability to pay interest and principal when due. The values of lower-quality debt securities, including floating rate loans, tend to be particularly sensitive to these changes. The values of securities also may decline for a number of other reasons that relate directly to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods and services, as well as the historical and prospective earnings of the issuer and the value of its assets. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Affiliated ETF Risk: To the extent the Fund invests in an affiliated underlying ETF, the Fund's investment performance and risks may be directly related to the investment performance and risks of the affiliated ETF. In addition, the Adviser and/or Sub-Adviser may have an incentive to take into account the effect on an affiliated ETF in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that affiliated ETF. Although the Adviser and/or Sub-Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. Collateralized Loan Obligation Risk: The risks of an investment in a collateralized loan obligation depend largely on the type of the collateral securities and the class of the collateralized loan obligation in which the Fund invests. Collateralized loan obligations are generally subject to credit, interest rate, valuation, liquidity, leverage, prepayment and extension risks. These securities also are subject to risk of default on or modification of the underlying asset, particularly during periods of economic downturn. Collateralized loan obligations carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. Collateralized loan obligations are divided into two or more classes, called “tranches,” each with a different credit rating and risk/return profile. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of credit risk. If there are defaults or the collateralized loan obligation's collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those of subordinated/equity tranches. Senior and mezzanine tranches are typically rated. The ratings reflect both the credit quality of underlying collateral as well as how much protection a given tranche is afforded by tranches that are subordinate to it. Exchange-Traded Funds Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by an underlying ETF in which it invests. In addition, the shares of an underlying ETF may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the NAV of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of the underlying ETF's investments, which may be exacerbated in less liquid markets. Forward Contracts Risk: A forward contract is a private, customizable agreement to buy or sell a specified currency, security or instrument at a future date at a price set at the time of the contract. Forward contracts settle at the end of the agreement and trade over-the-counter. The risks of forward contracts include, but are not limited to: (1) the success of the Sub-Adviser's ability to predict movements in the prices of individual currencies or securities, fluctuations in markets and movements in interest rates; (2) imperfect or no correlation between the changes in market value of the currencies or securities and the prices of such contracts; and (3) the risk that the counterparty will default on its obligations. Futures Contract Risk: A futures contract is a standardized agreement that calls for the purchase or sale of a specific asset at a specific price at a specific future time, or cash settlement of the terms of the contract. Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Sub-Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Sub-Adviser's investment techniques and decisions will produce the desired results. Models and Data Risk: The Sub-Adviser utilizes proprietary quantitative analysis and models to identify investment opportunities. There is a possibility that one or all of the quantitative models may fail to identify profitable opportunities at any time. Furthermore, the models may incorrectly identify opportunities and these misidentified opportunities may lead to substantial losses for the Fund. Models may be predictive in nature and such models may result in an incorrect assessment of future events. Data used in the construction of models may prove to be inaccurate or stale, which may result in losses for the Fund. Non-Senior Loans and Other Debt Securities Risk: Secured loans that are not first lien, loans that are unsecured and debt securities are subject to many of the same risks that affect senior loans; however they are often unsecured and/or lower in the issuer's capital structure than senior loans, and thus may be exposed to greater risk of default and lower recoveries in the event of a default. This risk can be further heightened in the case of below investment-grade instruments. Additionally, most fixed-income securities are fixed-rate and thus are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed to individuals as ordinary income. Repurchase Agreement Risk: Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. Repurchase agreements may be viewed as loans made by the Fund, which are collateralized by the securities subject to repurchase. If the Fund's counterparty should default on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss. Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. Reverse Repurchase Agreement Risk: Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement. Swaps Risk: A swap is a two-party contract that generally obligates the parties to exchange payments based on a specified reference security, basket of securities, security index or index component. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty's defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Systematic Strategies Related to Bond Investments Risk: With respect to the bond portion of the Fund's portfolio, to the extent to which the Model or comparable methods or strategies are employed, certain of the Sub-Adviser's securities analysis methods will rely on the assumption that the companies whose securities are purchased or sold, the rating agencies that review these securities, and other publicly available sources of information about these securities, are providing accurate and unbiased data. While the Sub-Adviser is alert to indications that data may be incorrect, there is always a risk that the Sub-Adviser's analysis may be compromised by inaccurate or misleading information. Thus, the Model the Sub-Adviser intends to utilize to manage the Fund's bond investments could lead to unsatisfactory investments. Certain aspects of the Sub-Adviser's investment process with respect to the Model are dependent on complex proprietary software. Analytical, coding and implementation errors present substantial risks to complex models and quantitative investment management strategies and the Sub-Adviser cannot guarantee that its internal controls will be effective in all circumstances. The Sub-Adviser might not be able to effectively implement the Model, and there can be no guarantee that the Fund will achieve the desired results. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. Fund Performance The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns for certain time periods compare with the average annual returns of the Bloomberg U.S. Aggregate Bond Index, a broad-based securities index, and an index with characteristics relevant to the Fund.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0070 0 0.0000 0.0070 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 72 224 390 871 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 153% of the average value of its portfolio. 1.53 The Fund's Principal Investment Strategy In pursuing its investment objective, the Fund seeks to outperform the Morningstar LSTA US Leveraged Loan Index (the “Index”) by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in Senior Loans.For purposes of this 80% test, “Senior Loans” are first lien senior secured floating rate bank loans. A Senior Loan is an advance or commitment of funds made by one or more banks or similar financial institutions, including the Fund, to one or more corporations, partnerships or other business entities and pays interest at a floating or adjusting rate that is determined periodically at a designated premium above a base lending rate. A Senior Loan is senior to all unsecured claims against the borrower and senior or equal to all other secured claims, meaning that, in the event of a bankruptcy, the Senior Loan, together with other first lien claims, is entitled to be the first to be repaid out of proceeds of the assets securing the loans, before other existing claims or interests receive repayment. However, in bankruptcy proceedings, there may be other claims, such as taxes or additional advances that take precedence. Senior Loans in which the Fund may invest, may include covenant-lite loans, which may contain fewer or no maintenance covenants compared to other loans.Each of the Fund's Senior Loan investments is expected to have no less than $250 million par outstanding.The Fund invests predominantly in Senior Loans that are made to businesses operating in North America, but may also invest in Senior Loans made to businesses operating outside of North America. The Fund may invest in Senior Loans directly, either from the borrower as part of a primary issuance or in the secondary market through assignments of portions of Senior Loans from third parties, or participations in Senior Loans, which are contractual relationships with an existing lender in a loan facility whereby the Fund purchases the right to receive principal and interest payments on a loan but the existing lender remains the record holder of the loan. Under normal market conditions, it is expected that the Fund's Senior Loan investments will maintain an average interest rate duration of less than 90 days. Loan interest rate duration is based on the actual remaining time until the applicable reference rate is reset for each individual loan.In selecting securities for the Fund, the Fund's sub-adviser, Blackstone Liquid Credit Strategies LLC (the “Sub-Adviser”), seeks to construct a portfolio of loans that it believes is less volatile than the general loan market. In addition, when making investments, the Sub-Adviser seeks to maintain appropriate liquidity and price transparency for the Fund. On an on-going basis, the Sub-Adviser adds or removes those individual loans that it believes will cause the Fund to outperform or underperform the Index. The Fund's strategy may result in a high portfolio turnover rate.When identifying prospective investment opportunities in Senior Loans, the Sub-Adviser currently intends to invest principally in Senior Loans that are below investment-grade quality and will rely on fundamental credit analysis in an effort to attempt to minimize the loss of the Fund's capital. While credit ratings assigned by Moody's Investors Service, Inc., S&P Global Ratings and/or Fitch Ratings Inc. (the “SROs” (statistical rating agencies)) will be considered, such ratings will not be determinative in the Sub-Adviser's process in the selection of specific debt securities (including Senior Loans). The Senior Loans and other securities that the Sub-Adviser is likely to select for investment in by the Fund will typically be rated below investment-grade quality by one or more of the SROs or, if unrated, will typically, in the opinion of the Sub-Adviser, be of similar credit quality. The Sub-Adviser expects to invest in Senior Loans, other loans and bonds of companies, including high yield securities (commonly known as “junk” bonds), collateralized loan obligations (“CLOs”) (including investment-grade and below investment-grade tranches of CLOs) and Rule 144A securities, possessing the following attributes, which it believes will help generate higher risk adjusted total returns.Leading, defensible market positions. The Sub-Adviser intends to invest in loans made to and bonds issued by companies that it believes have developed strong positions within their respective markets and exhibit the potential to maintain sufficient cash flows and profitability to service their obligations in a range of economic environments. The Sub-Adviser will seek companies that it believes possess advantages in scale, scope, customer loyalty, product pricing, or product quality versus their competitors, thereby minimizing business risk and protecting profitability.Investing in companies with positive cash flow. The Sub-Adviser intends to invest primarily in loans made to and bonds issued by established companies which have demonstrated a record of profitability and cash flows over several economic cycles. The Sub-Adviser believes such companies are well-positioned to maintain consistent cash flow to service and repay their obligations and maintain growth in their businesses or market share. The Sub-Adviser does not intend to invest primarily in start-up companies, companies in turnaround situations or companies with speculative business plans.Proven management teams. The Sub-Adviser intends to focus on investments in loans made to and bonds issued by companies that have experienced management teams with established track records of success. The Sub-Adviser will typically require companies to have in place proper incentives to align management's goals with the Fund's goals.Private equity sponsorship. The Sub-Adviser may seek to invest in loans made to and bonds issued by issuers sponsored by what it believes to be high-quality private equity firms. The Sub-Adviser believes that a private equity sponsor's willingness to invest significant sums of equity capital into a company is an implicit endorsement of the quality of the investment. Further, private equity sponsors of companies with significant investments at risk have the ability and a strong incentive to contribute additional capital in difficult economic times should operational issues arise.Diversification, concentration and reliance on other lenders. The Sub-Adviser will seek to invest broadly among companies and industries, thereby potentially reducing the risk of a downturn in any one company or industry having a disproportionate impact on the value of the Fund's portfolio. While the Fund looks to the underlying borrower of a bank loan, rather than the bank originating the loan, for purposes of determining the industry concentration of investments, it is possible that under a different interpretation the Fund may be deemed to concentrate its investments in the financial services industries. Loans, and the collateral securing them, are typically monitored by agents for the lenders, which may be the originating bank or banks. The Fund may be affected by the creditworthiness of the agent bank and other intermediate participants in a Senior Loan, in addition to the borrower, since rights that may exist under the loan against the borrower if the borrower defaults are typically asserted by or through the agent bank or intermediate participant. Agents are typically large commercial banks, although for Senior Loans that are not broadly syndicated they can also include thrift institutions, insurance companies or finance companies (or their affiliates). Such companies may be especially susceptible to the effects of changes in interest rates resulting from changes in U.S. or foreign fiscal or monetary policies, governmental regulations affecting capital raising activities or other economic or market fluctuations.If circumstances cause the Sub-Adviser to determine there is a likelihood the value of an existing investment will decline over time, the Fund may, if the Sub-Adviser believes that circumstances require, exit the investment. The circumstances giving rise to the Sub-Adviser's determination may, but will not necessarily, coincide with a downgrade of the Senior Loan or other security's credit rating.The Fund may also invest in repurchase agreements and enter into reverse repurchase agreements for cash management purposes. In pursuing its investment objective, the Fund seeks to outperform the Morningstar LSTA US Leveraged Loan Index (the “Index”) by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in Senior Loans. For purposes of this 80% test, “Senior Loans” are first lien senior secured floating rate bank loans. A Senior Loan is an advance or commitment of funds made by one or more banks or similar financial institutions, including the Fund, to one or more corporations, partnerships or other business entities and pays interest at a floating or adjusting rate that is determined periodically at a designated premium above a base lending rate. A Senior Loan is senior to all unsecured claims against the borrower and senior or equal to all other secured claims, meaning that, in the event of a bankruptcy, the Senior Loan, together with other first lien claims, is entitled to be the first to be repaid out of proceeds of the assets securing the loans, before other existing claims or interests receive repayment. However, in bankruptcy proceedings, there may be other claims, such as taxes or additional advances that take precedence. Senior Loans in which the Fund may invest, may include covenant-lite loans, which may contain fewer or no maintenance covenants compared to other loans. Each of the Fund's Senior Loan investments is expected to have no less than $250 million par outstanding. As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Senior Loan Risk: Investments in Senior Loans are subject to credit risk and general investment risk. Credit risk refers to the possibility that the borrower of a Senior Loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a Senior Loan will result in a reduction in the value of the Senior Loan and consequently a reduction in the value of the Fund's investments and a potential decrease in the net asset value (“NAV”) of the Fund. Senior Loans are also subject to the risk that the value of the collateral securing a Senior Loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. In addition, the Fund's access to the collateral may be limited by bankruptcy or other insolvency laws. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some Senior Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the Senior Loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund, such as invalidation of Senior Loans or causing interest previously paid to be refunded to the borrower. Senior Loans are also subject to high yield securities risks and liquidity risks described above. In addition, bank loans may be subject to extended settlement periods, which may impair the Fund's ability to sell or realize the full value of its loans in the event of a need to liquidate such loans in a compressed period of time. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. Collateralized Loan Obligation Risk: The risks of an investment in a collateralized loan obligation depend largely on the type of the collateral securities and the class of the collateralized loan obligation in which the Fund invests. Collateralized loan obligations are generally subject to credit, interest rate, valuation, liquidity, leverage, prepayment and extension risks. These securities also are subject to risk of default on or modification of the underlying asset, particularly during periods of economic downturn. Collateralized loan obligations carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. Collateralized loan obligations are divided into two or more classes, called “tranches,” each with a different credit rating and risk/return profile. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of credit risk. If there are defaults or the collateralized loan obligation's collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those of subordinated/equity tranches. Senior and mezzanine tranches are typically rated. The ratings reflect both the credit quality of underlying collateral as well as how much protection a given tranche is afforded by tranches that are subordinate to it. Financial Sector Risk: Financial services companies are subject to extensive governmental regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Liquidity Risk: There is no organized exchange on which loans are traded and reliable market quotations may not be readily available. A majority of the Fund's assets are likely to be invested in loans that are less liquid than securities traded on national exchanges. Illiquidity of the Fund's holdings may limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. Illiquidity of the Fund's holdings may also lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Loans with reduced liquidity involve greater risk than securities with more liquid markets. Available market quotations for such loans may vary over time, and if the credit quality of a loan unexpectedly declines, secondary trading of that loan may decline for a period of time. During periods of infrequent trading, valuing a loan can be more difficult and buying and selling a loan at an acceptable price can be more difficult and delayed. In the event that the Fund voluntarily or involuntarily liquidates portfolio assets during periods of infrequent trading, it may not receive full value for those assets. Therefore, elements of judgment may play a greater role in valuation of loans. To the extent that a secondary market exists for certain loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Management Risk: The Fund is actively managed. The Sub-Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Sub-Adviser's investment techniques and decisions will produce the desired results. Non-Senior Loans and Other Debt Securities Risk: Secured loans that are not first lien, loans that are unsecured and debt securities are subject to many of the same risks that affect senior loans; however they are often unsecured and/or lower in the issuer's capital structure than senior loans, and thus may be exposed to greater risk of default and lower recoveries in the event of a default. This risk can be further heightened in the case of below investment-grade instruments. Additionally, most fixed-income securities are fixed-rate and thus are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed to individuals as ordinary income. Repurchase Agreement Risk: Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. Repurchase agreements may be viewed as loans made by the Fund, which are collateralized by the securities subject to repurchase. If the Fund's counterparty should default on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss. Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. Reverse Repurchase Agreement Risk: Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0045 0 0.0000 0.0045 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 46 144 252 567 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 62% of the average value of its portfolio. 0.62 The Fund's Principal Investment Strategy Under normal circumstances, DoubleLine Capital LP (the “Sub-Adviser” or “DoubleLine”) will invest at least 80% of the Fund's net assets (plus the amount of borrowings for investment purposes) in a diversified portfolio of fixed income securities of any credit quality (subject to certain limits described below). The Fund will provide shareholders with at least 60 days' notice prior to any change in this 80% investment policy. Fixed income securities in which the Fund principally invests are defined as securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; inflation protected public obligations of the U.S. Treasury (“TIPS”); securities issued or guaranteed by state or local governments or their agencies or instrumentalities (commonly known as municipal bonds) (the Fund may invest up to 20% of its portfolio in municipal bonds); asset-backed securities (“ABS”) (which include the following: agency and non-agency residential mortgage-backed securities (“RMBS”), agency and non-agency commercial mortgage-backed securities (“CMBS”), and any other agency and non-agency asset-backed securities (“NAABS”)); collateralized debt obligations (“CDOs”); collateralized loan obligations (“CLOs”); collateralized bond obligations (“CBOs”); collateralized mortgage obligations (“CMOs”); and Real Estate Mortgage Investment Conduits (“REMICs”) and Re-REMICs (which are REMICs that have been resecuritized); stripped securities (i.e., interest rate only and principal only securities); zero coupon securities; foreign (including emerging markets) and domestic corporate bonds; sovereign debt; bank loans; preferred securities; and exchange-traded products, including exchange-traded funds and exchange-traded notes, that invest in fixed income securities. To the extent applicable, debt instruments that comprise fixed income securities may be either fixed rate securities, floating rate securities, or variable rate securities. The Fund may also invest in cash and other short-term instruments, as well as restricted securities. The Fund intends to invest at least 25% of its net assets, in the aggregate, in mortgage-backed securities of any maturity or type guaranteed by, or secured by collateral that is guaranteed by, the U.S. government, its agencies, instrumentalities or sponsored corporations, and privately issued mortgage-backed securities. The Fund may invest a substantial portion of its assets in U.S. agency mortgage pass-through securities. The term “U.S. agency mortgage pass-through security” refers to a category of pass-through securities backed by pools of mortgages and issued by one of several U.S. Government-sponsored enterprises: the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The Fund may seek to obtain exposure to U.S. agency mortgage pass-through securities through the use of “to-be-announced” or “TBA Transactions”. “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed security. Transactions in mortgage pass-through securities may occur through the use of TBA Transactions. TBA Transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA Transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined prior to settlement date. The Fund may settle a TBA Transaction on the settlement date by paying for and accepting actual receipt or delivery of the pools. The Fund may also sell its obligation to purchase the pools prior to the settlement date and enter into a new TBA Transaction for future delivery of pools of mortgage pass-through securities, sometimes referred to as a “TBA roll.”The Fund may invest up to 20% of its net assets in corporate high yield securities (commonly known as “junk” bonds). Under normal circumstances, the combined total of corporate, sovereign, non-agency and all other debt rated below investment-grade will not exceed 40% of the Fund's net assets. Below investment-grade securities are instruments that are rated BB+ or lower by S&P or Fitch Inc. or Ba1 or lower by Moody's or equivalent ratings by another registered NRSRO or, if unrated by an NRSRO, of comparable quality in the opinion of the Sub-Adviser. The Sub-Adviser strives to allocate securities broadly by industry and issuer in an attempt to reduce the impact of negative events on an industry or issuer. The Fund may invest up to 15% of its net assets in securities denominated in foreign currencies, and may invest beyond this limit in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 20% of its net assets in securities and instruments that are economically tied to emerging market countries. The Fund generally considers an issuer to be economically tied to an emerging market country if: (i) the issuer is organized under the laws of an emerging country; (ii) the issuer's securities are traded principally in an emerging country; or (iii) during the issuer's most recent fiscal year it derived at least 50% of its revenues, earnings before interest, taxes, depreciation, and amortization, or profits from goods produced or sold by, investments made in, or services performed in emerging countries, or it had at least 50% of its assets in emerging countries. The Sub-Adviser monitors the duration of the securities held by the Fund to seek to mitigate exposure to interest rate risk. Under normal circumstances, the Sub-Adviser seeks to maintain an investment portfolio with a weighted average effective duration between 1 and 3 years. The duration of the portfolio may vary materially from its target, from time to time. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. The Sub-Adviser actively manages the Fund's asset class exposure using a top-down approach based on analysis of sector fundamentals and rotates Fund assets among sectors in various markets to attempt to maximize return. Individual securities within asset classes are selected using a bottom-up approach. Under normal circumstances, the Sub-Adviser uses a controlled risk approach in managing the Fund's investments. The techniques of this approach attempt to control the principal risk components of the fixed income markets and include consideration of:• security selection within a given sector;• relative performance of the various market sectors;• the shape of the yield curve; and• fluctuations in the overall level of interest rates. Under normal circumstances, DoubleLine Capital LP (the “Sub-Adviser” or “DoubleLine”) will invest at least 80% of the Fund's net assets (plus the amount of borrowings for investment purposes) in a diversified portfolio of fixed income securities of any credit quality (subject to certain limits described below). Fixed income securities in which the Fund principally invests are defined as securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; inflation protected public obligations of the U.S. Treasury (“TIPS”); securities issued or guaranteed by state or local governments or their agencies or instrumentalities (commonly known as municipal bonds) (the Fund may invest up to 20% of its portfolio in municipal bonds); asset-backed securities (“ABS”) (which include the following: agency and non-agency residential mortgage-backed securities (“RMBS”), agency and non-agency commercial mortgage-backed securities (“CMBS”), and any other agency and non-agency asset-backed securities (“NAABS”)); collateralized debt obligations (“CDOs”); collateralized loan obligations (“CLOs”); collateralized bond obligations (“CBOs”); collateralized mortgage obligations (“CMOs”); and Real Estate Mortgage Investment Conduits (“REMICs”) and Re-REMICs (which are REMICs that have been resecuritized); stripped securities (i.e., interest rate only and principal only securities); zero coupon securities; foreign (including emerging markets) and domestic corporate bonds; sovereign debt; bank loans; preferred securities; and exchange-traded products, including exchange-traded funds and exchange-traded notes, that invest in fixed income securities.

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Asset-Backed and Mortgage-Backed Securities Risk: Asset-backed and mortgage-backed securities (residential and commercial) represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. These securities, in most cases, are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. These securities may be subject to liquidity risk as well as the risk of illiquidity and default on the underlying asset or mortgage, particularly during periods of economic downturn. The liquidity of mortgage-backed and asset-backed securities may change over time. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain asset-backed and mortgage-backed securities. In particular, during periods of falling interest rates, mortgage-backed securities will be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of a mortgage-backed security may extend, which may lock in a below-market interest rate, increase the security's duration, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, or the underlying assets or collateral may be insufficient if the issuer defaults. The values of certain types of mortgage-backed securities, such as inverse floaters and interest-only and principal-only securities, may be extremely sensitive to changes in interest rates and prepayment rates. Transactions in mortgage pass through securities may occur through the use of “to-be-announced” or “TBA Transactions”. Default by, or bankruptcy of, a counterparty to a TBA Transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA Transaction. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily net asset value (“NAV”) per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Bank Loan Risk: The Fund may invest in secured and unsecured participations in bank loans and assignments of such loans. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of both the financial institution and the underlying borrower. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. The Fund may also experience settlement delays with respect to bank loan trades, resulting in the proceeds from the sale of such loans not being readily available to make additional investments or to meet the Fund's redemption obligations. Participations by the Fund in a lender's portion of a bank loan typically will result in the Fund having a contractual relationship only with such lender, not with the borrower. The Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling a loan participation and only upon receipt by such lender of such payments from the borrower. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other lenders through set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund may assume the credit risk of both the borrower and the lender selling the participation. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans. Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. Collateralized Debt Obligations Risk: The risks of an investment in a collateralized debt obligation depend largely on the type of the collateral securities and the class of the debt obligation in which the Fund invests. Collateralized debt obligations are generally subject to many of the same risks of investing as debt securities and asset-backed securities, including credit, interest rate, valuation, liquidity, prepayment and extension risks. These securities also are subject to risk of default on the underlying assets, particularly during periods of economic downturn. Collateralized Loan Obligation Risk: The risks of an investment in a collateralized loan obligation depend largely on the type of the collateral securities and the class of the collateralized loan obligation in which the Fund invests. Collateralized loan obligations are generally subject to credit, interest rate, valuation, liquidity, prepayment and extension risks. These securities also are subject to risk of default on the underlying asset, particularly during periods of economic downturn. Collateralized loan obligations carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. Collateralized loan obligations are divided into two or more classes, called “tranches,” each with a different credit rating and risk/return profile. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of credit risk. If there are defaults or the collateralized loan obligation's collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those of subordinated/equity tranches. Senior and mezzanine tranches are typically rated. The ratings reflect both the credit quality of underlying collateral as well as how much protection a given tranche is afforded by tranches that are subordinate to it. Collateralized Bond Obligation Risk: The pool of high yield securities underlying collateralized bond obligations is typically separated into groupings called tranches representing different degrees of credit quality. The higher quality tranches have greater degrees of protection and pay lower interest rates. The lower tranches, with greater risk, pay higher interest rates. Collateralized Mortgage Obligation Risk: The expected average life of collateralized mortgage obligations (“CMOs”) is determined using mathematical models that incorporate prepayment assumptions and other factors that involve estimates of future economic and market conditions. These estimates may vary from actual future results, particularly during periods of extreme market volatility. Further, under certain market conditions, the average weighted life of certain CMOs may not accurately reflect the price volatility of such securities. For example, in periods of supply and demand imbalances in the market for such securities and/or in periods of sharp interest rate movements, the prices of CMOs may fluctuate to a greater extent than would be expected from interest rate movements alone. CMOs issued by private entities are not obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities and are not guaranteed by any government agency, although the securities underlying a CMO may be subject to a guarantee. Therefore, if the collateral securing the CMO, as well as any third party credit support or guarantees, is insufficient to make payments when due, the holder could sustain a loss. Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies. Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries. Exchange Traded Products Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by the ETPs in which it invests. In addition, the shares of certain ETPs may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value of an exchange traded fund's (“ETF”) shares) for a number of reasons. For example, supply and demand for shares of an ETF or market disruptions may cause the market price of the ETF to deviate from the value of the ETF's investments, which may be exacerbated in less liquid markets. The value of an exchange traded note may also differ from the valuation of its reference market due to changes in the issuer's credit rating. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Sub-Adviser. Interest Rate Only and Principal Only Securities Risk: Interest rate only and principal only securities are acutely sensitive to interest rate changes and to the rate of principal prepayments. These securities are volatile in price and may have lower liquidity. Investment in ETNs: The value of an exchanged traded note (“ETN”) may be influenced by time to maturity, supply and demand, volatility and lack of liquidity, changes in interest rates, and economic, legal, political or geographic events that affect the referenced market. Because ETNs are debt securities, they are subject to credit risk. There are typically no periodic interest payments for ETNs, and the amount of principal payable at maturity may decline, depending in part on the performance of an underlying index or asset. A Fund could lose all or some of the amount invested in an ETN. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Sub-Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Sub-Adviser's investment techniques and decisions will produce the desired results. Municipal Obligations Risk: Issuers, including governmental issuers, may be unable to pay their obligations as they come due. The values of municipal obligations may be adversely affected by local political and economic conditions and developments. In addition, the values of municipal obligations that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Political Risk: A significant restructuring of federal income tax rates or even serious discussion on the topic in Congress could cause municipal bond prices to fall. The demand for municipal securities is strongly influenced by the value of tax-exempt income to investors. Lower income tax rates could reduce the advantage of owning municipals. Preferred Securities Risk: Generally, preferred security holders have no or limited voting rights with respect to the issuing company. In addition, preferred securities are generally senior to common stock, but may be subordinated to bonds and other debt instruments in a company's capital structure and therefore may be subject to greater credit risk than those debt instruments. In the event an issuer of preferred securities experiences economic difficulties, the issuer's preferred securities may lose substantial value due to the increased likelihood of deferred interest or dividend payments and the fact that the preferred security may be subordinated to other securities of the same issuer. Further, because many preferred securities pay interest or dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the preferred securities held by the Fund are likely to decline. In addition, to the extent preferred securities allow holders to convert the preferred securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of the Fund's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a preferred security having a higher than average yield may cause a decrease in the Fund's yield. Privately Issued Securities Risk: The Fund will invest in privately-issued securities, including those which are issued pursuant to Rule 144A or Regulation S under the Securities Act of 1933, or Section 4(a)(2) of the Securities Act 1933. Privately-issued securities are securities that have not been registered under the Securities Act and as a result are subject to legal restrictions on resale. Privately-issued securities are not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. REMIC Risk: The issuer of a series of mortgage pass-through securities may elect to be treated as a Real Estate Mortgage Investment Conduit (“REMIC”). REMICs include governmental and/or private entities that issue a fixed pool of mortgages secured by an interest in real property. REMICs are similar to collateralized mortgage obligations (“CMOs”) in that they issue multiple classes of securities but, unlike CMOs, which are required to be structured as debt securities, REMICs may be structured as indirect ownership interests in the underlying assets of the REMICs themselves. The risks associated with an investment in a particular CMO or REMIC class vary substantially depending on the combination of rights associated with that class. An investment in the most subordinated classes of a CMO or REMIC bears a disproportionate share of the risks associated with mortgage-backed security generally, be it credit risk, prepayment or extension risk (the risk of a security's expected maturity being reduced or lengthened in duration due to a change of the timing of payment), interest rate risk, income risk, market risk, liquidity risk or any other risk associated with a debt or equity instrument with similar features to the relevant class. As a result, an investment in the most subordinated classes of a CMO or REMIC is often riskier than an investment in other types of mortgage-backed securities. Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. Unconstrained Sector Risk: The Fund may invest a substantial portion of its assets within one or more economic sectors or industries, which may change from time to time. Greater investment focus on one or more sectors or industries increases the potential for volatility and the risk that events negatively affecting such sectors or industries could reduce returns, potentially causing the value of the Fund's Shares to decrease, perhaps significantly. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. Zero-Coupon Bond Risk: Zero-coupon bonds usually trade at a deep discount from their face or par values and are subject to greater market value fluctuations from changing interest rates than debt obligations of comparable maturities that make current distributions of interest.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0055 0 0.0000 0.0055 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 56 176 307 689 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 40% of the average value of its portfolio. 0.40 The Fund's Principal Investment Strategy Under normal circumstances, DoubleLine Capital LP (the “Sub-Adviser” or “DoubleLine”) will invest at least 80% of the Fund's net assets in a portfolio of fixed income securities of any credit quality.Fixed income securities in which the Fund principally invests include securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; inflation protected public obligations of the U.S. Treasury; agency and non-agency residential mortgage-backed securities (“RMBS”); agency and non-agency commercial mortgage-backed securities (“CMBS”); agency and non-agency asset-backed securities (“ABS”); domestic corporate bonds; fixed income securities issued by foreign corporations and foreign governments including emerging markets; bank loans (primarily senior loans, including loan participations or assignments whose loan syndication exceeds $300 million); municipal bonds; and other securities (such as perpetual bonds) bearing fixed interest rates of any maturity.The Fund may also invest in collateralized loan obligations, floating rate securities (including floating rate loans), variable rate securities, Rule 144A securities, and repurchase agreements and may enter into reverse repurchase agreements. The Fund may conduct foreign currency transactions on a spot (i.e., cash) or forward basis (i.e., by entering into forward contracts to purchase or sell foreign currencies).The Fund intends to invest at least 20% of its net assets in mortgage-backed securities of any maturity or type guaranteed by, or secured by collateral that is guaranteed by, the U.S. Government, its agencies, instrumentalities or sponsored corporations, or in privately issued mortgage-backed securities. The Fund may invest a substantial portion of its assets in U.S. agency mortgage pass-through securities. The term “U.S. agency mortgage pass-through security” refers to a category of pass-through securities backed by pools of mortgages and issued by one of several U.S. Government-sponsored enterprises: the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae)” or the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The Fund may seek to obtain exposure to U.S. agency mortgage pass-through securities through the use of “to-be-announced” or “TBA Transactions”. “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed securities. TBA Transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA Transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined prior to settlement date. The Fund may settle a TBA Transaction on the settlement date by paying for and accepting actual receipt or delivery of the pools. The Fund may also sell its obligation to purchase the pools prior to the settlement date and enter into a new TBA Transaction for future delivery of pools of mortgage pass-through securities, sometimes referred to as a “TBA roll.”The Fund may invest up to 25% of its net assets in corporate high yield securities (commonly known as “junk” bonds). Under normal circumstances, the combined total of corporate, sovereign, non-agency and all other debt rated below investment-grade will not exceed 40% of the Fund's net assets. The Sub-Adviser strives to allocate below investment-grade securities broadly by industry and issuer in an attempt to reduce the impact of negative events on an industry or issuer. Below investment-grade securities are instruments that are rated BB+ or lower by S&P or Fitch Inc. or Ba1 or lower by Moody's or equivalent ratings by another registered NRSRO, or, if unrated by an NRSRO, of comparable quality in the opinion of the Sub-Adviser.The Fund may invest up to 15% of its net assets in securities denominated in foreign currencies, and may invest beyond this limit in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 25% of its net assets in securities and instruments that are economically tied to emerging market countries. The Fund generally considers an issuer to be economically tied to an emerging market country if: (i) the issuer is organized under the laws of an emerging country; (ii) the issuer's securities are traded principally in an emerging country; or (iii) during the issuer's most recent fiscal year it derived at least 50% of its revenues, earnings before interest, taxes, depreciation, and amortization, or profits from goods produced or sold by, investments made in, or services performed in emerging countries, or it had at least 50% of its assets in emerging countries.The Sub-Adviser monitors the duration of the securities held by the Fund to seek to mitigate exposure to interest rate risk. Under normal circumstances, the Sub-Adviser seeks to maintain an investment portfolio with a weighted average effective duration of no less than 1 year and no more than 8 years. The duration of the portfolio may vary materially from its target, from time to time. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. The Fund may use futures, including U.S. Treasury futures, to manage the Fund's duration and yield curve exposure.The Sub-Adviser actively manages the Fund's asset class exposure using a top-down approach based on analysis of sector fundamentals and rotates Fund assets among sectors in various markets to attempt to maximize return. Individual securities within asset classes are selected using a bottom-up approach. Under normal circumstances, the Sub-Adviser uses a controlled risk approach in managing the Fund's investments. The techniques of this approach attempt to control the principal risk components of the fixed income markets and include consideration of:• Security selection within a given sector;• Relative performance of the various market sectors;• The shape of the yield curve; and• Fluctuations in the overall level of interest rates. Under normal circumstances, DoubleLine Capital LP (the “Sub-Adviser” or “DoubleLine”) will invest at least 80% of the Fund's net assets in a portfolio of fixed income securities of any credit quality. Fixed income securities in which the Fund principally invests include securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; inflation protected public obligations of the U.S. Treasury; agency and non-agency residential mortgage-backed securities (“RMBS”); agency and non-agency commercial mortgage-backed securities (“CMBS”); agency and non-agency asset-backed securities (“ABS”); domestic corporate bonds; fixed income securities issued by foreign corporations and foreign governments including emerging markets; bank loans (primarily senior loans, including loan participations or assignments whose loan syndication exceeds $300 million); municipal bonds; and other securities (such as perpetual bonds) bearing fixed interest rates of any maturity.

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Asset-Backed and Mortgage-Backed Securities Risk: Asset-backed and mortgage-backed securities (residential and commercial) represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. These securities, in most cases, are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. These securities may be subject to liquidity risk as well as the risk of illiquidity and default on the underlying asset or mortgage, particularly during periods of economic downturn. The liquidity of mortgage-backed and asset-backed securities may change over time. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain asset-backed and mortgage-backed securities. In particular, during periods of falling interest rates, mortgage-backed securities will be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of a mortgage-backed security may extend, which may lock in a below-market interest rate, increase the security's duration, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, or the underlying assets or collateral may be insufficient if the issuer defaults. The values of certain types of mortgage-backed securities, such as inverse floaters and interest-only and principal-only securities, may be extremely sensitive to changes in interest rates and prepayment rates. Transactions in mortgage pass through securities may occur through the use of “to-be-announced” or “TBA Transactions”. Default by, or bankruptcy of, a counterparty to a TBA Transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA Transaction. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily net asset value (“NAV”) per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Bank Loan Risk: The Fund may invest in secured and unsecured participations in bank loans and assignments of such loans. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of both the financial institution and the underlying borrower. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. The Fund may also experience settlement delays with respect to bank loan trades, resulting in the proceeds from the sale of such loans not being readily available to make additional investments or to meet the Fund's redemption obligations. Participations by the Fund in a lender's portion of a bank loan typically will result in the Fund having a contractual relationship only with such lender, not with the borrower. The Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling a loan participation and only upon receipt by such lender of such payments from the borrower. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other lenders through set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund may assume the credit risk of both the borrower and the lender selling the participation. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. Collateralized Loan Obligation Risk: The risks of an investment in a collateralized loan obligation depend largely on the type of the collateral securities and the class of the collateralized loan obligation in which the Fund invests. Collateralized loan obligations are generally subject to credit, interest rate, valuation, liquidity, leverage, prepayment and extension risks. These securities also are subject to risk of default on or modification of the underlying asset, particularly during periods of economic downturn. Collateralized loan obligations carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. Collateralized loan obligations are divided into two or more classes, called “tranches,” each with a different credit rating and risk/return profile. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of credit risk. If there are defaults or the collateralized loan obligation's collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those of subordinated/equity tranches. Senior and mezzanine tranches are typically rated. The ratings reflect both the credit quality of underlying collateral as well as how much protection a given tranche is afforded by tranches that are subordinate to it. Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies. Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries. Forward Contracts Risk: A forward contract is a private, customizable agreement to buy or sell a specified currency, security or instrument at a future date at a price set at the time of the contract. Forward contracts settle at the end of the agreement and trade over-the-counter. The risks of forward contracts include, but are not limited to: (1) the success of the Sub-Adviser's ability to predict movements in the prices of individual currencies or securities, fluctuations in markets and movements in interest rates; (2) imperfect or no correlation between the changes in market value of the currencies or securities and the prices of such contracts; and (3) the risk that the counterparty will default on its obligations. Futures Contract Risk: A futures contract is a standardized agreement that calls for the purchase or sale of a specific asset at a specific price at a specific future time, or cash settlement of the terms of the contract. Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Sub-Adviser. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Sub-Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Sub-Adviser's investment techniques and decisions will produce the desired results. Municipal Obligations Risk: Issuers, including governmental issuers, may be unable to pay their obligations as they come due. The values of municipal obligations may be adversely affected by local political and economic conditions and developments. In addition, the values of municipal obligations that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may cause interest received and distributed by the Fund to shareholders to be taxable and may result in a significant decline in the values of such municipal obligations. Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Perpetual Bond Risk: Perpetual bonds offer a fixed return with no maturity date. Because they never mature, perpetual bonds can be more volatile than other types of bonds that have a maturity date and may have heightened sensitivity to changes in interest rates. If market interest rates rise significantly, the interest rate paid by a perpetual bond may be much lower than the prevailing interest rate. Perpetual bonds are also subject to credit risk with respect to the issuer. In addition, because perpetual bonds may be callable after a set period of time, there is the risk that the issuer may recall the bond. Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed to individuals as ordinary income. Repurchase Agreement Risk: Repurchase agreements may be viewed as loans made by the Fund, which are collateralized by the securities subject to repurchase. If the Fund's counterparty should default on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss. Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. Reverse Repurchase Agreement Risk: Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement. Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. In addition, investment in derivative variable rate securities, such as inverse floaters, whose rates vary inversely with market rates of interest, or range floaters or capped floaters, whose rates are subject to periodic or lifetime caps, or in securities that pay a rate of interest determined by applying a multiple to the variable rate involves special risks as compared to investment in a fixed-rate security and may involve leverage. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade frequently, and their value may be impaired when the Fund needs to liquidate such securities. When-Issued, TBA and Delayed Delivery Securities Risk: The Fund may purchase securities on a when-issued, to-be-announced (“TBA”) or delayed delivery basis and may purchase securities on a forward commitment basis. The purchase price of the securities is typically fixed at the time of the commitment, but delivery and payment can take place a month or more after the date of the commitment. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchase of securities on a when-issued, TBA, delayed delivery, or forward commitment basis may give rise to investment leverage, and may result in increased volatility of the Fund's NAV. Default by, or bankruptcy of, a counterparty to a when-issued, TBA or delayed delivery transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. The Financial Industry Regulatory Authority, Inc. imposes mandatory margin requirements for certain types of when-issued, TBA, delayed delivery or forward commitment transactions, with limited exceptions. Such transactions require mandatory collateralization which may increase the cost of such transactions and impose added operational complexity.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0055 0 0.0000 0.0055 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 56 176 307 689 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 122% of the average value of its portfolio. 1.22 The Fund's Principal Investment Strategy Loomis, Sayles & Company, L.P. (the “Sub-Adviser”) actively manages the Fund's assets utilizing a “multi-asset credit strategy” that seeks to capture credit risk premiums in markets that it believes can offer strong risk-adjusted return potential over a full market cycle.Under normal circumstances, the Sub-Adviser will invest at least 80% of the Fund's net assets (plus the amount of borrowings for investment purposes), directly, or indirectly through underlying exchanged-traded funds (“ETFs”), in debt obligations.Debt obligations in which the Fund principally invests include securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; inflation protected public obligations of the U.S. Treasury; securitized credit securities, such as agency and non-agency residential mortgage-backed securities, agency and non-agency commercial mortgage-backed securities, agency and non-agency asset-backed securities and collateralized debt obligations (including collateralized loan obligations) (“Securitized Credit Securities”); debt obligations issued by domestic or foreign private sector entities, including issuers located in emerging markets; debt obligations issued by foreign governments and their agencies and instrumentalities, including issuers located in emerging markets; debt obligations issued by supranational entities; debt securities issued pursuant to Rule 144A or Regulation S under the Securities Act of 1933; structured notes; and bank loans (primarily senior loans). Such debt obligations may be issued at fixed, variable, floating, adjustable or zero coupon rates. The Fund may also invest in hybrid securities that combine debt and equity characteristics, such as preferred securities, convertible preferred securities and contingent convertible securities (“CoCos”). The Fund may also enter into repurchase agreements and reverse repurchase agreements. The Fund may invest up to 10% of its assets in non-U.S. dollar-denominated debt obligations and any such debt obligations will be hedged back to the U.S. dollar.The Fund may also invest in derivatives including: futures and forward contracts; swaps (including credit default swaps, total return swaps, interest rate swaps, and index swaps); options and swaptions; interest rate caps, floors and collars; warrants and other rights; and contracts for differences. Such derivatives may include those derivatives where the underlying assets are based on one or more securities, indices, currencies, interest rates and loans, and may be deliverable or non-deliverable. The Fund may conduct foreign currency transactions on a spot or forward basis. The Fund may use derivatives to hedge the Fund's portfolio (e.g., to hedge against currency fluctuations), as well as for investment purposes (e.g., to gain exposure to certain issuers or markets). The Fund may also invest in ETFs registered under the Investment Company Act of 1940, as amended (the “1940 Act”) (including ETFs advised by SSGA Funds Management, Inc. (“SSGA FM” or the “Adviser”)) to gain exposure to certain asset classes and/or securities.The Fund may invest in debt obligations of any credit quality and may invest up to 100% of its net assets in debt instruments that are rated below investment grade or are unrated but determined by the Sub-Adviser to be of comparable quality (commonly known as “high-yield” investments or “junk” bonds). The Fund may invest up to 60% of its net assets in bank loans and may invest up to 25% of its net assets in Securitized Credit Securities. While the Fund looks to the underlying borrower of a bank loan, rather than the bank originating the loan, for purposes of determining the industry concentration of investments, it is possible that under a different interpretation the Fund may be deemed to concentrate its investments in the financial services industries.The Sub-Adviser monitors the duration of the securities held by the Fund to seek to mitigate exposure to interest rate risk. Under normal circumstances, the Sub-Adviser seeks to maintain an investment portfolio with a weighted average effective duration of 0 to 7 years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.In pursuing its investment objective, the Fund seeks to outperform the State Street Loomis Sayles Opportunistic Bond Composite Index, a composite benchmark comprising 50% investment grade corporate bonds, 25% high yield corporate bonds, and 25% senior loans. The investment grade corporate bond portion of the composite benchmark is represented by the Bloomberg US Corporate Bond Index, the high yield corporate bond portion is represented by the Bloomberg US High Yield 2% Issuer Capped Index, and the senior loan portion is represented by the Morningstar LSTA US Leveraged Loan Index.The Sub-Adviser determines asset class allocation by evaluating the current stage of the credit cycle and the attractiveness of the various asset classes. Such evaluation features macroeconomic, asset class and industry analysis driven by real-time market data, economic releases, and trading patterns, coupled with the Sub-Adviser's quantitative economic and market cycle identifying models. In selecting securities for the Fund within a specific asset class, the Sub-Adviser utilizes a security-specific valuation framework driven by the portfolio management team's daily interaction with the Sub-Adviser's sector teams integrating quantitative analysis with the Sub-Adviser's internal fundamental research.The Sub-Adviser uses a comprehensive risk controlled approach in managing the Fund's investments to seek to control the principal risk components of the fixed income markets. The decision to sell or adjust positions is driven by the relative value of the security, spread, and risk-adjusted return expectations versus current levels. The Sub-Adviser typically sells a security (i) when it is no longer consistent with the Sub-Adviser's view of market trends; (ii) when it is no longer attractive on a relative value basis, given any inherent risks; or (iii) to control for risk. Under normal circumstances, the Sub-Adviser will invest at least 80% of the Fund's net assets (plus the amount of borrowings for investment purposes), directly, or indirectly through underlying exchanged-traded funds (“ETFs”), in debt obligations. Debt obligations in which the Fund principally invests include securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; inflation protected public obligations of the U.S. Treasury; securitized credit securities, such as agency and non-agency residential mortgage-backed securities, agency and non-agency commercial mortgage-backed securities, agency and non-agency asset-backed securities and collateralized debt obligations (including collateralized loan obligations) (“Securitized Credit Securities”); debt obligations issued by domestic or foreign private sector entities, including issuers located in emerging markets; debt obligations issued by foreign governments and their agencies and instrumentalities, including issuers located in emerging markets; debt obligations issued by supranational entities; debt securities issued pursuant to Rule 144A or Regulation S under the Securities Act of 1933; structured notes; and bank loans (primarily senior loans). Such debt obligations may be issued at fixed, variable, floating, adjustable or zero coupon rates. The Sub-Adviser determines asset class allocation by evaluating the current stage of the credit cycle and the attractiveness of the various asset classes. Such evaluation features macroeconomic, asset class and industry analysis driven by real-time market data, economic releases, and trading patterns, coupled with the Sub-Adviser's quantitative economic and market cycle identifying models.

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Asset-Backed and Mortgage-Backed Securities Risk: Asset-backed and mortgage-backed securities (residential and commercial) represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. These securities, in most cases, are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. These securities may be subject to liquidity risk as well as the risk of illiquidity and default on the underlying asset or mortgage, particularly during periods of economic downturn. The liquidity of mortgage-backed and asset-backed securities may change over time. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain asset-backed and mortgage-backed securities. In particular, during periods of falling interest rates, mortgage-backed securities will be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of a mortgage-backed security may extend, which may lock in a below-market interest rate, increase the security's duration, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, or the underlying assets or collateral may be insufficient if the issuer defaults. The values of certain types of mortgage-backed securities, such as inverse floaters and interest-only and principal-only securities, may be extremely sensitive to changes in interest rates and prepayment rates. Transactions in mortgage pass through securities may occur through the use of “to-be-announced” or “TBA Transactions”. Default by, or bankruptcy of, a counterparty to a TBA Transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA Transaction. Bank Loan Risk: The Fund may invest in secured and unsecured participations in bank loans and assignments of such loans. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of both the financial institution and the underlying borrower. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. The Fund may also experience settlement delays with respect to bank loan trades, resulting in the proceeds from the sale of such loans not being readily available to make additional investments or to meet the Fund's redemption obligations. Participations by the Fund in a lender's portion of a bank loan typically will result in the Fund having a contractual relationship only with such lender, not with the borrower. The Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling a loan participation and only upon receipt by such lender of such payments from the borrower. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other lenders through set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund may assume the credit risk of both the borrower and the lender selling the participation. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily net asset value (“NAV”) per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Affiliated ETF Risk: To the extent the Fund invests in an affiliated underlying ETF, the Fund's investment performance and risks may be directly related to the investment performance and risks of the affiliated ETF. In addition, the Adviser and/or Sub-Adviser may have an incentive to take into account the effect on an affiliated ETF in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that affiliated ETF. Although the Adviser and/or Sub-Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. Collateralized Debt Obligations Risk: The risks of an investment in a collateralized debt obligation depend largely on the type of the collateral securities and the class of the debt obligation in which the Fund invests. Collateralized debt obligations are generally subject to many of the same risks of investing as debt securities and asset-backed securities, including credit, interest rate, valuation, liquidity, prepayment and extension risks. These securities also are subject to risk of default on the underlying assets, particularly during periods of economic downturn. Collateralized Loan Obligation Risk: The risks of an investment in a collateralized loan obligation depend largely on the type of the collateral securities and the class of the collateralized loan obligation in which the Fund invests. Collateralized loan obligations are generally subject to credit, interest rate, valuation, liquidity, prepayment and extension risks. These securities also are subject to risk of default on the underlying asset, particularly during periods of economic downturn. Collateralized loan obligations carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. Collateralized loan obligations are divided into two or more classes, called “tranches,” each with a different credit rating and risk/return profile. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of credit risk. If there are defaults or the collateralized loan obligation's collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those of subordinated/equity tranches. Senior and mezzanine tranches are typically rated. The ratings reflect both the credit quality of underlying collateral as well as how much protection a given tranche is afforded by tranches that are subordinate to it. Contracts for Difference Risk: A contract for difference (“CFD”) is a privately negotiated contract between two parties, buyer and seller, stipulating that the seller will pay to or receive from the buyer the difference between the nominal value of the underlying instrument at the opening of the contract and that instrument's value at the end of the contract. A CFD offers exposure to price changes in an underlying security without ownership of such security, typically by providing investors the ability to trade on margin. CFDs are subject to illiquidity risk because the liquidity of contracts for difference is based on the liquidity of the underlying instrument. CFD's are also subject to the risk that the counterparty to the CFDs transaction may be unable or unwilling to make payments or to otherwise honor its financial obligations under the terms of the contract. If the Fund buys a long CFD and the underlying security is worth less at the end of the contract, the Fund would be required to make a payment to the seller and would suffer a loss. Convertible Securities Risk: Convertible securities may be subordinate to other debt securities issued by the same issuer. Issuers of convertible securities are often not as strong financially as issuers with higher credit ratings. Convertible securities typically provide yields lower than comparable non-convertible securities. Their values may be more volatile than those of non-convertible securities, reflecting changes in the values of the securities into which they are convertible. The Fund may invest in contingent convertible securities (“CoCos”), which subject the Fund to the risk of the occurrence of a triggering event which, depending on the underlying circumstances, may result in the issuer converting the security to an equity interest or writing down the principal value of such securities (either partially or in full). Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries. Exchange-Traded Funds Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by an underlying ETF in which it invests. In addition, the shares of an underlying ETF may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the NAV of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of the underlying ETF's investments, which may be exacerbated in less liquid markets. Financial Sector Risk: Financial services companies are subject to extensive governmental regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate. Forward Contracts Risk: A forward contract is a private, customizable agreement to buy or sell a specified currency, security or instrument at a future date at a price set at the time of the contract. Forward contracts settle at the end of the agreement and trade over-the-counter. The risks of forward contracts include, but are not limited to: (1) the success of the Sub-Adviser's ability to predict movements in the prices of individual currencies or securities, fluctuations in markets and movements in interest rates; (2) imperfect or no correlation between the changes in market value of the currencies or securities and the prices of such contracts; and (3) the risk that the counterparty will default on its obligations. Futures Contract Risk: A futures contract is a standardized agreement that calls for the purchase or sale of a specific asset at a specific price at a specific future time, or cash settlement of the terms of the contract. Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Sub-Adviser. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Sub-Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Sub-Adviser's investment techniques and decisions will produce the desired results. Models and Data Risk: The Sub-Adviser utilizes proprietary quantitative analysis and models to identify investment opportunities. There is a possibility that one or all of the quantitative models may fail to identify profitable opportunities at any time. Furthermore, the models may incorrectly identify opportunities and these misidentified opportunities may lead to substantial losses for the Fund. Models may be predictive in nature and such models may result in an incorrect assessment of future events. Data used in the construction of models may prove to be inaccurate or stale, which may result in losses for the Fund. Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Options Risk: The Fund's successful use of options depends on the ability of the Adviser to forecast market movements correctly. When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option's expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. The effective use of options also depends on the Fund's ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. The sale of options by the Fund may create investment leverage. Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed to individuals as ordinary income. Preferred Securities Risk: Generally, preferred security holders have no or limited voting rights with respect to the issuing company. In addition, preferred securities are generally senior to common stock, but may be subordinated to bonds and other debt instruments in a company's capital structure and therefore may be subject to greater credit risk than those debt instruments. In the event an issuer of preferred securities experiences economic difficulties, the issuer's preferred securities may lose substantial value due to the increased likelihood of deferred interest or dividend payments and the fact that the preferred security may be subordinated to other securities of the same issuer. Further, because many preferred securities pay interest or dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the preferred securities held by the Fund are likely to decline. In addition, to the extent preferred securities allow holders to convert the preferred securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of the Fund's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a preferred security having a higher than average yield may cause a decrease in the Fund's yield. Repurchase Agreement Risk: Repurchase agreements may be viewed as loans made by the Fund, which are collateralized by the securities subject to repurchase. If the Fund's counterparty should default on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss. Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. Reverse Repurchase Agreement Risk: Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement. Rights or Warrants Risk: A warrant gives the holder a right to purchase, at any time during a specified period, a predetermined number of shares of common stock at a fixed price. Rights are similar to warrants but typically have a shorter duration and are issued by a company to existing stockholders to provide those holders the right to purchase additional shares of stock at a later date. Warrants and rights may lack a liquid secondary market for resale. The prices of warrants and rights may fluctuate as a result of changes in the value of the underlying security or obligation or due to speculation in the market for the warrants or rights or other factors. Prices of warrants and rights do not necessarily move in tandem with the prices of their underlying securities; their prices may have significant volatility and it is possible that the Fund will lose its entire investment in a warrant or right. The Fund's failure to exercise a warrant or subscription right to purchase common shares in an issuer might result in the dilution of the Fund's interest in the issuing company. Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. Structured Notes Risk: Structured notes, a type of derivative instrument, are generally privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a specific asset, benchmark asset, market or interest rate. Structured notes involve risks including interest rate risk, credit risk and market risk. Structured notes may be volatile, and the possibility of default by the financial institution or counterparty may be greater for these instruments than for other types of derivative instruments. Swaps Risk: A swap is a two-party contract that generally obligates the parties to exchange payments based on a specified reference security, basket of securities, security index or index component. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty's defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. In addition, investment in derivative variable rate securities, such as inverse floaters, whose rates vary inversely with market rates of interest, or range floaters or capped floaters, whose rates are subject to periodic or lifetime caps, or in securities that pay a rate of interest determined by applying a multiple to the variable rate involves special risks as compared to investment in a fixed-rate security and may involve leverage. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Zero-Coupon Bond Risk: Zero-coupon bonds usually trade at a deep discount from their face or par values and are subject to greater market value fluctuations from changing interest rates than debt obligations of comparable maturities that make current distributions of interest.

Capital appreciation is a secondary objective when consistent with the Fund's primary objective. Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0040 0 0.0000 0.0040 “Other expenses” and “Total annual Fund operating expenses” have been restated to reflect current fees. Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 41 128 224 505 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 12% of the average value of its portfolio. 0.12 The Fund's Principal Investment Strategy In pursuing its investment objective, under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) in municipal bonds that pay income that is exempt from regular federal income tax.The municipal bonds selected by Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”), the investment sub-adviser to the Fund, may include tax-exempt municipal securities issued by states, cities, counties, districts, territories or possessions of the United States and the District of Columbia and their respective subdivisions, agencies, authorities and instrumentalities. Municipal bonds may include state and local general obligation bonds, revenue bonds, pre-refunded bonds, insured bonds and municipal lease obligations. Securities selected by the Sub-Adviser may include when-issued securities. Under normal market conditions, the Fund's investment portfolio will consist primarily of municipal bonds rated Baa3/BBB-/BBB- or higher by Moody's Investors Service, Inc. (“Moody's”), S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”), respectively; however, the Fund may invest in municipal bonds of any credit quality, including up to 20% of its net assets in bonds rated Ba1/BB+/BB+ or lower (bonds considered below investment grade and commonly referred to as “high yield” or “junk” bonds) by Moody's, S&P or Fitch, respectively (or unrated bonds judged by the Sub-Adviser to be of comparable quality). Under normal circumstances, the Sub-Adviser will target a weighted average duration for the Fund's portfolio between 4.5 – 7 years and a weighted average maturity for the Fund's portfolio between 5 – 15 years.In selecting securities for the Fund, the Sub-Adviser utilizes a value-oriented strategy which is designed to identify higher-yielding and undervalued municipal bonds that offer above-average total return potential. In identifying potential municipal bond investments to purchase or sell, the Sub-Adviser's investment process may incorporate, among other things, credit analysis and surveillance, sector analysis, industry concentration analysis, trading strategies, and yield curve and structural analysis. The Sub-Adviser may choose to sell municipal bonds with deteriorating credit and/or limited upside potential compared to other available bonds.The Fund may also invest in cash and cash equivalents or money market instruments (including money market funds advised by SSGA Funds Management, Inc. (“SSGA FM” or the “Adviser”), the investment adviser to the Fund) for cash management purposes. In pursuing its investment objective, under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) in municipal bonds that pay income that is exempt from regular federal income tax. The municipal bonds selected by Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”), the investment sub-adviser to the Fund, may include tax-exempt municipal securities issued by states, cities, counties, districts, territories or possessions of the United States and the District of Columbia and their respective subdivisions, agencies, authorities and instrumentalities. Municipal bonds may include state and local general obligation bonds, revenue bonds, pre-refunded bonds, insured bonds and municipal lease obligations. In selecting securities for the Fund, the Sub-Adviser utilizes a value-oriented strategy which is designed to identify higher-yielding and undervalued municipal bonds that offer above-average total return potential.

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Municipal Obligations Risk: Issuers, including governmental issuers, may be unable to pay their obligations as they come due. The values of municipal obligations may be adversely affected by local political and economic conditions and developments. In addition, the values of municipal obligations that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may cause interest received and distributed by the Fund to shareholders to be taxable and may result in a significant decline in the values of such municipal obligations. Political Risk: A significant restructuring of federal income tax rates or even serious discussion on the topic in Congress could cause municipal bond prices to fall. The demand for municipal securities is strongly influenced by the value of tax-exempt income to investors. Lower income tax rates could reduce the advantage of owning municipals. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily net asset value (“NAV”) per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Cash Position Risk: If the Fund holds a significant position in cash or cash equivalents, its investment returns may be adversely affected, and the Fund may not achieve its investment objective. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Sub-Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Sub-Adviser's investment techniques and decisions will produce the desired results. Money Market Fund Investment Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. Tax Exemption Risk: There is no guarantee that the Fund's income will be exempt from federal or state income taxes. Events occurring after the date of issuance of a municipal bond or after the Fund's acquisition of a municipal bond may result in a determination that interest on that bond is includible in gross income for federal income tax purposes retroactively to its date of issuance. Such a determination may cause a portion of prior distributions by the Fund to its shareholders to be taxable to those shareholders in the year of receipt. Federal or state changes in income or alternative minimum tax rates or in the tax treatment of municipal bonds may make municipal bonds less attractive as investments and cause them to decline in value. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. “Value” Investing Risk: There is a possibility that the Fund's investments in securities believed by the Sub-Adviser to be undervalued may not realize their perceived value for extended periods of time or may never realize their perceived value. The securities in which the Fund invests may respond differently to market and other developments than other types of securities, and may underperform other securities and/or the market as a whole. When-Issued Securities Risk: The Fund may purchase securities on a when-issued or forward commitment basis. The purchase price of such securities is typically fixed at the time of the commitment, with delivery and payment taking place in the future. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchase of securities on a when-issued or forward commitment basis may give rise to investment leverage, and may result in increased volatility of the Fund's NAV. Default by, or bankruptcy of, a counterparty to a when-issued transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. Financial Industry Regulatory Authority, Inc. rules impose mandatory margin requirements for certain types of when-issued or forward commitment transactions, with limited exceptions. Such transactions require mandatory collateralization which may increase the cost of such transactions and impose added operational complexity.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0050 0 0.0000 0.0050 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 51 160 280 628 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 198% of the average value of its portfolio. 1.98 The Fund's Principal Investment Strategy Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) directly, or indirectly through underlying exchange-traded funds (“ETFs”), in fixed income securities.In particular, the Fund primarily allocates its assets among ETFs that each focus on one or more of the following sectors of the fixed income market: (i) securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; (ii) inflation protected public obligations of the U.S. Treasury; (iii) U.S. corporate securities; (iv) U.S. mortgage-backed securities; (v) high yield securities (commonly known as “junk” bonds); (vi) international government and corporate securities, including emerging markets; (vii) first lien senior secured floating rate bank loans; (viii) floating and variable rate securities; (ix) asset-backed securities; and (x) cash equivalents (i.e., securities maturing in less than one year) (each, a “Fixed Income Sector” and collectively, the “Fixed Income Sectors”). The Fund may also invest directly in fixed income securities within any of the Fixed Income Sectors.SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”), the Fund's investment adviser, allocates the Fund's assets based on a risk-aware, top-down approach to construct a portfolio that seeks to overweight the Fund's exposure to the most attractive Fixed Income Sectors. The Adviser develops long-term structural and intermediate cyclical views to establish the Fund's asset allocation through analyzing macroeconomic factors, financial conditions, and industry and sector trends. The Fund may invest in individual fixed income securities to increase the Fund's exposure to the issuers of such securities and for risk management purposes. Individual fixed income securities are identified through rigorous fundamental research including financial analysis of cash flows, capital structure, industry and issuer-specific fundamentals, and relative value assessment. It is possible the Fund may not have exposure to all Fixed Income Sectors at all times.The Fund may invest in ETFs that pay fees to the Adviser and its affiliates for management, marketing or other services. The Fund or ETFs in which the Fund invests may use derivative instruments (primarily forward and futures contracts; interest rate, credit default, and total return swaps; and options) to hedge currency exposure and manage yield, interest rate exposure (also known as duration), and credit quality exposure. In addition, the Fund may invest in cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds, including money market funds advised by the Adviser. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) directly, or indirectly through underlying exchange-traded funds (“ETFs”), in fixed income securities. In particular, the Fund primarily allocates its assets among ETFs that each focus on one or more of the following sectors of the fixed income market: (i) securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; (ii) inflation protected public obligations of the U.S. Treasury; (iii) U.S. corporate securities; (iv) U.S. mortgage-backed securities; (v) high yield securities (commonly known as “junk” bonds); (vi) international government and corporate securities, including emerging markets; (vii) first lien senior secured floating rate bank loans; (viii) floating and variable rate securities; (ix) asset-backed securities; and (x) cash equivalents (i.e., securities maturing in less than one year) (each, a “Fixed Income Sector” and collectively, the “Fixed Income Sectors”).

Individual fixed income securities are identified through rigorous fundamental research including financial analysis of cash flows, capital structure, industry and issuer-specific fundamentals, and relative value assessment. As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Asset Allocation Risk: The Fund's investment performance depends upon the successful allocation by the Adviser of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser's allocation techniques and decisions will produce the desired results. Exchange-Traded Funds Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by an underlying ETF in which it invests. In addition, the shares of an underlying ETF may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value (“NAV”) of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of the underlying ETF's investments, which may be exacerbated in less liquid markets. Affiliated ETF Risk: To the extent the Fund invests in an affiliated underlying ETF, the Fund's investment performance and risks may be directly related to the investment performance and risks of the affiliated ETF. In addition, the Adviser may have an incentive to take into account the effect on an affiliated ETF in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that affiliated ETF. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Cash Position Risk: If the Fund holds a significant position in cash or cash equivalents, its investment returns may be adversely affected, and the Fund may not achieve its investment objective. Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies. Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries. Forward Contracts Risk: A forward contract is a private, customizable agreement to buy or sell a specified currency, security or instrument at a future date at a price set at the time of the contract. Forward contracts settle at the end of the agreement and trade over-the-counter. The risks of forward contracts include, but are not limited to: (1) the success of the Sub-Adviser's ability to predict movements in the prices of individual currencies or securities, fluctuations in markets and movements in interest rates; (2) imperfect or no correlation between the changes in market value of the currencies or securities and the prices of such contracts; and (3) the risk that the counterparty will default on its obligations. Futures Contract Risk: A futures contract is a standardized agreement that calls for the purchase or sale of a specific asset at a specific price at a specific future time, or cash settlement of the terms of the contract. Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Adviser. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results. Money Market Fund Investment Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. Mortgage-Related and Other Asset-Backed Securities Risk: Investments in mortgage-related and other asset-backed securities are subject to the risk of significant credit downgrades, illiquidity, and defaults to a greater extent than many other types of fixed-income investments. The liquidity of mortgage-related and asset-backed securities may change over time. During periods of falling interest rates, mortgage- and asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of mortgage- and asset-backed securities may extend, which may lock in a below-market interest rate, increase the security's duration and interest rate sensitivity, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, and the underlying assets or collateral may be insufficient if the issuer defaults. Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Options Risk: The Fund's successful use of options depends on the ability of the Adviser to forecast market movements correctly. When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option's expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. The effective use of options also depends on the Fund's ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. The sale of options by the Fund may create investment leverage. Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed to individuals as ordinary income. Repurchase Agreement Risk: Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. Repurchase agreements may be viewed as loans made by the Fund, which are collateralized by the securities subject to repurchase. If the Fund's counterparty should default on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss. Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. Senior Loan Risk: Investments in senior loans are subject to credit risk and general investment risk. Credit risk refers to the possibility that the borrower of a senior loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a senior loan will result in a reduction in the value of the senior loan and consequently a reduction in the value of the Fund's investments and a potential decrease in the NAV of the Fund. Senior loans are also subject to the risk that the value of the collateral securing a senior loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. In addition, the Fund's access to the collateral may be limited by bankruptcy or other insolvency laws. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some senior loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the senior loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund, such as invalidation of senior loans or causing interest previously paid to be refunded to the borrower. Senior loans are also subject to high yield securities risks and liquidity risks described above. In addition, bank loans may be subject to extended settlement periods, which may impair the Fund's ability to sell or realize the full value of its loans in the event of a need to liquidate such loans in a compressed period of time. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans. Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. Swaps Risk: A swap is a two-party contract that generally obligates the parties to exchange payments based on a specified reference security, basket of securities, security index or index component. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty's defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. In addition, investment in derivative variable rate securities, such as inverse floaters, whose rates vary inversely with market rates of interest, or range floaters or capped floaters, whose rates are subject to periodic or lifetime caps, or in securities that pay a rate of interest determined by applying a multiple to the variable rate involves special risks as compared to investment in a fixed-rate security and may involve leverage. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0035 0 0.0000 0.0035 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 36 113 197 443 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 85% of the average value of its portfolio. 0.85 The Fund's Principal Investment Strategy SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) primarily invests the assets of the Fund among exchange traded products (“ETPs”) that provide balanced exposure to domestic and international debt and equity securities. The Fund typically allocates approximately 60% of its assets to equity securities, though this percentage can vary based on the Adviser's tactical decisions. The Adviser's investment process relies on proprietary quantitative models as well as the Adviser's fundamental views regarding factors that may not be captured by the quantitative models. The allocations to each asset class will change over time as the Adviser's expectations of each asset class shift. The Fund's indirect holdings by virtue of investing in ETPs representing these asset classes consist of a diversified mix of domestic and international, including emerging market, equity securities across all market capitalizations, investment-grade and high yield government and corporate bonds (high yield bonds are commonly known as “junk” bonds), inflation protected securities, mortgage pass-through securities, commercial mortgage backed securities, asset backed securities, commodities and real estate investment trusts (“REITs”). The Fund, through its investments in ETPs, will generally invest at least 30% of its assets in securities of issuers economically tied to countries other than the U.S. and will generally hold securities of issuers economically tied to at least three countries, including the U.S. In determining if a security is economically tied to a non-U.S. country, the Fund generally looks to the country of incorporation of the issuer as listed on Bloomberg L.P., a widely recognized provider of market information. However, the Adviser may determine a security is economically tied to a non-U.S. country based on other factors, such as an issuer's country of domicile, where more than 50% of an issuer's revenues are generated or where an issuer's primary exchange is located. As a result, a security may be economically tied to more than one country.ETPs in which the Fund invests include exchange-traded funds registered under the Investment Company Act of 1940, as amended (the “1940 Act”) (“Underlying ETFs”), exchange traded commodity trusts; and exchange traded notes (“ETNs”). The Fund may invest in ETPs that are qualified publicly traded partnerships (“QPTPs”). In addition, the Fund may invest in certain ETPs that pay fees to the Adviser and its affiliates for management, marketing or other services. In addition, the Fund may invest in cash and cash equivalents or money market instruments, such as money market funds (including money market funds advised by the Adviser).

In determining if a security is economically tied to a non-U.S. country, the Fund generally looks to the country of incorporation of the issuer as listed on Bloomberg L.P., a widely recognized provider of market information.

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Non-U.S. Securities Risk: Non-U.S. securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading markets. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Asset Allocation Risk: The Fund's investment performance depends upon the successful allocation by the Adviser of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser's allocation techniques and decisions will produce the desired results. Modeling Risk: The Adviser uses quantitative models in an effort to enhance returns and manage risk. Any imperfections, errors or limitations in these models could limit any benefit to the Fund from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those expected or desired by the Adviser. There can be no assurance that the models will behave as expected in all market conditions. In addition, computer programming used to create quantitative models, or the data on which such models operate, might contain one or more errors. Exchange Traded Products Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by the ETPs in which it invests. In addition, the shares of certain ETPs may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value (“NAV”) of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an Underlying ETF or market disruptions may cause the market price of the Underlying ETF to deviate from the value of the Underlying ETF's investments, which may be exacerbated in less liquid markets. The value of an ETN may also differ from the valuation of its reference market due to changes in the issuer's credit rating. The Fund is subject to the following risks indirectly through its investments in ETPs: Affiliated ETP Risk: The Adviser may receive management or other fees from the ETPs (“Affiliated ETPs”) in which the Fund may invest, as well as a management fee for managing the Fund. It is possible that a conflict of interest among the Fund and the Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Fund and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which the Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETPs. In addition, the Adviser may have an incentive to take into account the effect on an Affiliated ETP in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that Affiliated ETP. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Cash Position Risk: If the Fund holds a significant position in cash or cash equivalents, its investment returns may be adversely affected, and the Fund may not achieve its investment objective. Commodities Risk: Commodity prices can have significant volatility, and exposure to commodities can cause the NAV of Fund Shares to decline or fluctuate in a rapid and unpredictable manner. A liquid secondary market may not exist for certain commodity investments, which may make it difficult for the Fund to sell them at a desirable price or at the price at which it is carrying them. Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Depositary Receipts Risk: Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries. Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Adviser. Large-Capitalization Securities Risk: Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. Larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial, or other market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results. Mid-Capitalization Securities Risk: The securities of mid-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of mid-sized companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of mid-sized issuers may be illiquid or may be restricted as to resale, and their values may be volatile. Money Market Fund Investment Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. Mortgage-Related and Other Asset-Backed Securities Risk: Investments in mortgage-related and other asset-backed securities are subject to the risk of significant credit downgrades, illiquidity, and defaults to a greater extent than many other types of fixed-income investments. The liquidity of mortgage-related and asset-backed securities may change over time. During periods of falling interest rates, mortgage- and asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of mortgage- and asset-backed securities may extend, which may lock in a below-market interest rate, increase the security's duration and interest rate sensitivity, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, and the underlying assets or collateral may be insufficient if the issuer defaults. Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed to individuals as ordinary income. Real Estate Sector Risk: An investment in a real property company may be subject to risks similar to those associated with direct ownership of real estate, including, by way of example, the possibility of declines in the value of real estate, losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, environmental liability, zoning laws, regulatory limitations on rents, property taxes, and operating expenses. Some real property companies have limited diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. REIT Risk: REITs are subject to the risks associated with investing in the real estate sector in general. In particular, a REIT may be affected by changes in the values of the properties that the REIT owns or operates or that underlie the mortgages or similar real estate interests in which the REIT invests. In addition, REITs may be affected by changes to interest rates or property taxes. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. In addition, a REIT could fail to qualify for favorable tax or regulatory treatment. Smaller capitalization REITs may be more volatile and may involve more risk than larger capitalization REITs. Equity REITs earn income from leasing properties and realize gains and losses from the sale of properties, and are therefore subject to the risk of extended vacancies, limitations on rents, the failure to collect rents, and the costs of obtaining financing for purchasing real estate. Mortgage REITs receive principal and interest payments from the owners of mortgage properties and are therefore subject to the credit risk of borrowers, lack of mortgage funds, and prepayment on underlying mortgage loans. Small-Capitalization Securities Risk: The securities of small-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of smaller companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of smaller issuers may be illiquid or may be restricted as to resale, and their values may have significant volatility. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. Returns on investments in securities of small-capitalization companies could trail the returns on investments in securities of larger companies. Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. Tax Risk-Qualifying Income: Regulated investment companies are subject to favorable tax treatment under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). To qualify as a regulated investment company, the Fund must derive at least 90% of its gross income for each taxable year from sources generating “qualifying income.” Income derived from direct and certain indirect investments in commodities is not qualifying income. Thus, income from the Fund's investments in certain commodities-related investments may cause the Fund not to qualify as a regulated investment company. The Fund may also invest up to 25% of its total assets in one or more QPTPs, including ETPs that are QPTPs and whose principal activities are the buying and selling of commodities or options, futures, or forwards with respect to commodities. Although income from QPTPs is generally qualifying income, if an ETP intending to qualify as a QPTP fails to qualify as a QPTP, the income generated from the Fund's investment in the ETP may not be qualifying income. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

The returns after taxes can exceed the returns before taxes due to an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. 0.1602 0.0705 0.0755 0.1453 0.0568 0.0638 0.0961 0.0498 0.0558 0.2206 0.1075 0.1145 0.0730 -0.0036 0.0201 State Street® Income Allocation ETF Investment Objective The State Street Income Allocation ETF (the “Fund”) seeks to provide total return by focusing on investments in income and yield-generating assets. Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0050 0 0.0000 0.0050 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 51 160 280 628 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 57% of the average value of its portfolio. 0.57 The Fund's Principal Investment Strategy SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) primarily invests the assets of the Fund among exchange traded products (“ETPs”) that provide exposure to five primary asset classes: (i) domestic and international equity securities; (ii) domestic and international investment-grade and high yield debt securities (commonly known as “junk” bonds); (iii) hybrid equity/debt securities (such as preferred stock and convertible securities); (iv) first lien senior secured floating rate bank loans, commonly referred to as “Senior Loans”; and (v) real estate investment trusts (“REITs”), including equity REITs and mortgage REITs.The Fund's allocation among those asset classes will be in proportions consistent with the Adviser's evaluation of the expected returns and risks of each asset class as well as the allocation that, in the Adviser's view, will best meet the Fund's investment objective. The Adviser's investment process relies on proprietary quantitative models as well as the Adviser's fundamental views regarding factors that may not be captured by the quantitative models. The allocations to each asset class will change over time as the Adviser's expectations of each asset class shift. The Fund's indirect holdings by virtue of investing in ETPs representing these asset classes will consist of a diversified mix of domestic and international, including emerging markets, equity securities, investment-grade and high yield government and corporate bonds, hybrid securities such as preferred stock and convertible securities, inflation protected securities, Senior Loans and REITs.ETPs in which the Fund invests include exchange-traded funds registered under the Investment Company Act of 1940, as amended (the “1940 Act”) (“Underlying ETFs”), and exchange traded notes (“ETNs”). The Fund may invest in certain ETPs that pay fees to the Adviser and its affiliates for management, marketing or other services. In addition, the Fund may invest in cash and cash equivalents or money market instruments, such as money market funds (including money market funds advised by the Adviser). SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) primarily invests the assets of the Fund among exchange traded products (“ETPs”) that provide exposure to five primary asset classes: (i) domestic and international equity securities; (ii) domestic and international investment-grade and high yield debt securities (commonly known as “junk” bonds); (iii) hybrid equity/debt securities (such as preferred stock and convertible securities); (iv) first lien senior secured floating rate bank loans, commonly referred to as “Senior Loans”; and (v) real estate investment trusts (“REITs”), including equity REITs and mortgage REITs.

The Adviser's investment process relies on proprietary quantitative models as well as the Adviser's fundamental views regarding factors that may not be captured by the quantitative models. The allocations to each asset class will change over time as the Adviser's expectations of each asset class shift. As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Asset Allocation Risk: The Fund's investment performance depends upon the successful allocation by the Adviser of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser's allocation techniques and decisions will produce the desired results. Modeling Risk: The Adviser uses quantitative models in an effort to enhance returns and manage risk. Any imperfections, errors or limitations in these models could limit any benefit to the Fund from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those expected or desired by the Adviser. There can be no assurance that the models will behave as expected in all market conditions. In addition, computer programming used to create quantitative models, or the data on which such models operate, might contain one or more errors. Exchange Traded Products Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by the ETPs in which it invests. In addition, the shares of certain ETPs may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value (“NAV”) of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an Underlying ETF or market disruptions may cause the market price of the Underlying ETF to deviate from the value of the Underlying ETF's investments, which may be exacerbated in less liquid markets. The value of an ETN may also differ from the valuation of its reference market due to changes in the issuer's credit rating. The Fund is subject to the following risks indirectly through its investments in ETPs: Affiliated ETP Risk: The Adviser may receive management or other fees from the ETPs (“Affiliated ETPs”) in which the Fund may invest, as well as a management fee for managing the Fund. It is possible that a conflict of interest among the Fund and the Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Fund and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which the Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETPs. In addition, the Adviser may have an incentive to take into account the effect on an Affiliated ETP in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that Affiliated ETP. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Cash Position Risk: If the Fund holds a significant position in cash or cash equivalents, its investment returns may be adversely affected, and the Fund may not achieve its investment objective. Convertible Securities Risk: Convertible securities may be subordinate to other debt securities issued by the same issuer. Issuers of convertible securities are often not as strong financially as issuers with higher credit ratings. Convertible securities typically provide yields lower than comparable non-convertible securities. Their values may be more volatile than those of non-convertible securities, reflecting changes in the values of the securities into which they are convertible. Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies. Depositary Receipts Risk: Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries. Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Adviser. Infrastructure-Related Companies Risk: Infrastructure-related companies include companies that primarily own, manage, develop and/or operate infrastructure assets, including transportation, utility, energy and/or telecommunications assets. Investment in infrastructure-related securities entails exposure to adverse economic, regulatory, political, legal, and other conditions or events affecting the issuers of such securities. Certain infrastructure-related entities, particularly telecommunications and utilities companies, are subject to extensive regulation by various governmental authorities. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect infrastructure-related companies. Infrastructure-related companies may also be affected by service interruption and/or legal challenges due to environmental, operational or other conditions or events, and the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. Large-Capitalization Securities Risk: Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. Larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial, or other market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results. Mid-Capitalization Securities Risk: The securities of mid-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of mid-sized companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of mid-sized issuers may be illiquid or may be restricted as to resale, and their values may be volatile. Money Market Fund Investment Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. Non-U.S. Securities Risk: Non-U.S. securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading markets. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Preferred Securities Risk: Generally, preferred security holders have no or limited voting rights with respect to the issuing company. In addition, preferred securities are generally senior to common stock, but may be subordinated to bonds and other debt instruments in a company's capital structure and therefore may be subject to greater credit risk than those debt instruments. In the event an issuer of preferred securities experiences economic difficulties, the issuer's preferred securities may lose substantial value due to the increased likelihood of deferred interest or dividend payments and the fact that the preferred security may be subordinated to other securities of the same issuer. Further, because many preferred securities pay interest or dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the preferred securities held by the Fund are likely to decline. In addition, to the extent preferred securities allow holders to convert the preferred securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of the Fund's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a preferred security having a higher than average yield may cause a decrease in the Fund's yield. Real Estate Sector Risk: An investment in a real property company may be subject to risks similar to those associated with direct ownership of real estate, including, by way of example, the possibility of declines in the value of real estate, losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, environmental liability, zoning laws, regulatory limitations on rents, property taxes, and operating expenses. Some real property companies have limited diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. REIT Risk: REITs are subject to the risks associated with investing in the real estate sector in general. In particular, a REIT may be affected by changes in the values of the properties that the REIT owns or operates or that underlie the mortgages or similar real estate interests in which the REIT invests. In addition, REITs may be affected by changes to interest rates or property taxes. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. In addition, a REIT could fail to qualify for favorable tax or regulatory treatment. Smaller capitalization REITs may be more volatile and may involve more risk than larger capitalization REITs. Equity REITs earn income from leasing properties and realize gains and losses from the sale of properties, and are therefore subject to the risk of extended vacancies, limitations on rents, the failure to collect rents, and the costs of obtaining financing for purchasing real estate. Mortgage REITs receive principal and interest payments from the owners of mortgage properties and are therefore subject to the credit risk of borrowers, lack of mortgage funds, and prepayment on underlying mortgage loans. Senior Loan Risk: Investments in Senior Loans are subject to credit risk and general investment risk. Credit risk refers to the possibility that the borrower of a Senior Loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a Senior Loan will result in a reduction in the value of the Senior Loan and consequently a reduction in the value of the Fund's investments and a potential decrease in the NAV of the Fund. Senior Loans are also subject to the risk that the value of the collateral securing a Senior Loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. In addition, the Fund's access to the collateral may be limited by bankruptcy or other insolvency laws. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some Senior Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the Senior Loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund, such as invalidation of Senior Loans or causing interest previously paid to be refunded to the borrower. Senior Loans are also subject to high yield securities risks and liquidity risks described above. In addition, bank loans may be subject to extended settlement periods, which may impair the Fund's ability to sell or realize the full value of its loans in the event of a need to liquidate such loans in a compressed period of time. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans. Small-Capitalization Securities Risk: The securities of small-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of smaller companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of smaller issuers may be illiquid or may be restricted as to resale, and their values may have significant volatility. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. Returns on investments in securities of small-capitalization companies could trail the returns on investments in securities of larger companies. Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Fund Performance The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns for certain time periods compare with the average annual returns of relevant broad-based securities indexes and the Bloomberg US Long Government/Credit Bond Index, an index with characteristics relevant to the Fund.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0050 0 0.0000 0.0050 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 51 160 280 628 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 31% of the average value of its portfolio. 0.31 The Fund's Principal Investment Strategy Under normal circumstances, SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) invests at least 80% of the net assets of the Fund among exchange traded products (“ETPs”) that provide exposure to the following primary asset classes: (i) inflation protected securities issued by the United States government, its agencies and/or instrumentalities, as well as inflation protected securities issued by foreign governments, agencies, and/or instrumentalities; (ii) domestic and international real estate securities; (iii) commodities; (iv) publicly-traded domestic and international infrastructure companies; and (v) publicly-traded domestic and international companies in natural resources and/or commodities businesses. Publicly-traded companies in infrastructure businesses may include energy, industrial, and utility companies. Publicly-traded companies in natural resources and/or commodities businesses may include agriculture, energy, and metals and mining companies. The Fund's allocation among these asset classes will be in proportions consistent with the Adviser's evaluation of the expected returns and risks of each asset class as well as the allocation that, in the Adviser's view, will best meet the Fund's investment objective. The Adviser's investment process relies on proprietary quantitative models as well as the Adviser's fundamental views regarding qualitative factors that may not be captured by the quantitative models. The allocations to each asset class will change over time as the Adviser's expectations of each asset class shift. The Fund's indirect holdings by virtue of investing in ETPs representing those asset classes will consist of a diversified mix of domestic and international equity securities, including emerging markets, government bonds, inflation protected securities, commodities and real estate investment trusts (“REITs”). The Fund may invest in ETPs that gain exposure to commodities through the use of derivatives. The Adviser considers real return to be a rate of return above the rate of inflation over a market cycle.ETPs in which the Fund invests include exchange-traded funds registered under the Investment Company Act of 1940, as amended (the “1940 Act”) (“Underlying ETFs”), exchange traded commodity trusts; and exchange traded notes (“ETNs”). The Fund may invest in ETPs that are qualified publicly traded partnerships (“QPTPs”). In addition, the Fund may invest in certain ETPs that pay fees to the Adviser and its affiliates for management, marketing or other services. In addition, the Fund may invest in cash and cash equivalents or money market instruments, such as money market funds (including money market funds advised by the Adviser). Under normal circumstances, SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) invests at least 80% of the net assets of the Fund among exchange traded products (“ETPs”) that provide exposure to the following primary asset classes: (i) inflation protected securities issued by the United States government, its agencies and/or instrumentalities, as well as inflation protected securities issued by foreign governments, agencies, and/or instrumentalities; (ii) domestic and international real estate securities; (iii) commodities; (iv) publicly-traded domestic and international infrastructure companies; and (v) publicly-traded domestic and international companies in natural resources and/or commodities businesses. The Fund's allocation among these asset classes will be in proportions consistent with the Adviser's evaluation of the expected returns and risks of each asset class as well as the allocation that, in the Adviser's view, will best meet the Fund's investment objective. The Adviser's investment process relies on proprietary quantitative models as well as the Adviser's fundamental views regarding qualitative factors that may not be captured by the quantitative models. The allocations to each asset class will change over time as the Adviser's expectations of each asset class shift. The Adviser considers real return to be a rate of return above the rate of inflation over a market cycle. As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Asset Allocation Risk: The Fund's investment performance depends upon the successful allocation by the Adviser of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser's allocation techniques and decisions will produce the desired results. Modeling Risk: The Adviser uses quantitative models in an effort to enhance returns and manage risk. Any imperfections, errors or limitations in these models could limit any benefit to the Fund from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those expected or desired by the Adviser. There can be no assurance that the models will behave as expected in all market conditions. In addition, computer programming used to create quantitative models, or the data on which such models operate, might contain one or more errors. Exchange Traded Products Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by the ETPs in which it invests. In addition, the shares of certain ETPs may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value (“NAV”) of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an Underlying ETF or market disruptions may cause the market price of the Underlying ETF to deviate from the value of the Underlying ETF's investments, which may be exacerbated in less liquid markets. The value of an ETN may also differ from the valuation of its reference market due to changes in the issuer's credit rating. The Fund is subject to the following risks indirectly through its investments in ETPs: Affiliated ETP Risk: The Adviser may receive management or other fees from the ETPs (“Affiliated ETPs”) in which the Fund may invest, as well as a management fee for managing the Fund. It is possible that a conflict of interest among the Fund and the Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Fund and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which the Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETPs. In addition, the Adviser may have an incentive to take into account the effect on an Affiliated ETP in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that Affiliated ETP. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Agriculture Companies Risk: Economic forces that affect agricultural markets, as well as government policies and regulations affecting agriculture companies, could adversely impact the Fund's investments. Agricultural and livestock production and trade flows are significantly affected by government policies and regulations. Governmental policies affecting agriculture companies, such as taxes, tariffs, duties, subsidies and import and export restrictions on agricultural commodities, commodity products and livestock, can influence agriculture company profitability, the planting/raising of certain crops/livestock versus other uses of resources, the location and size of crop and livestock production, whether unprocessed or processed commodity products are traded and the volume and types of imports and exports. In addition, companies in the agriculture sector must comply with a broad range of environmental laws and regulations. Additional or more stringent environmental laws and regulations may be enacted in the future and such changes could have a material adverse effect on the business of such companies. In addition, agriculture companies may be significantly affected by adverse weather, pollution and/or disease which could limit or halt production. Cash Position Risk: If the Fund holds a significant position in cash or cash equivalents, its investment returns may be adversely affected, and the Fund may not achieve its investment objective. Commodities Risk: Commodity prices can have significant volatility, and exposure to commodities can cause the NAV of Fund Shares to decline or fluctuate in a rapid and unpredictable manner. A liquid secondary market may not exist for certain commodity investments, which may make it difficult for the Fund to sell them at a desirable price or at the price at which it is carrying them. Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Depositary Receipts Risk: Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. Derivatives Risk: Derivative transactions can create investment leverage and may have significant volatility. It is possible that a derivative transaction will result in a much greater loss than the principal amount invested, and it may be difficult to close out a derivative transaction at a favorable time or price. The counterparty to a derivatives contract may be unable or unwilling to make timely settlement payments, return margin, or otherwise honor its obligations. A derivatives transaction may not have the effect or behave in the manner anticipated. Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries. Energy Sector Risk: Issuers in energy-related industries can be significantly affected by fluctuations in energy prices and supply and demand of energy fuels. Markets for various energy-related commodities can have significant volatility, and are subject to control or manipulation by large producers or purchasers. Companies in the energy sector may need to make substantial expenditures, and to incur significant amounts of debt, in order to maintain or expand their reserves. Oil and gas exploration and production can be significantly affected by natural disasters as well as changes in exchange rates, interest rates, government regulation, world events and economic conditions. These companies may be at risk for environmental damage claims. Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Industrial Sector Risk: Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Transportation securities, a component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs. Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Adviser. Infrastructure-Related Companies Risk: Infrastructure-related companies include companies that primarily own, manage, develop and/or operate infrastructure assets, including transportation, utility, energy and/or telecommunications assets. Investment in infrastructure-related securities entails exposure to adverse economic, regulatory, political, legal, and other conditions or events affecting the issuers of such securities. Certain infrastructure-related entities, particularly telecommunications and utilities companies, are subject to extensive regulation by various governmental authorities. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect infrastructure-related companies. Infrastructure-related companies may also be affected by service interruption and/or legal challenges due to environmental, operational or other conditions or events, and the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. Large-Capitalization Securities Risk: Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. Larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial, or other market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results. Materials Sector Risk: Many materials companies are significantly affected by the level and volatility of commodity prices, exchange rates, import controls, worldwide competition, environmental policies and consumer demand. At times, worldwide production of industrial materials has exceeded demand as a result of over-building or economic downturns, leading to poor investment returns or losses. Other risks may include liabilities for environmental damage and general civil liabilities, depletion of resources, and mandated expenditures for safety and pollution control. The materials sector may also be affected by economic cycles, technical progress, labor relations, and government regulations. Metals and Mining Companies Risk: Metals and mining companies can be significantly affected by events relating to international political and economic developments, energy conservation, the success of exploration projects, commodity prices, and tax and other government regulations. Investments in metals and mining companies may be speculative and may be subject to greater price volatility than investments in other types of companies. Risks of metals and mining investments include: changes in international monetary policies or economic and political conditions that can affect the supply of precious metals and consequently the value of metals and mining company investments; the United States or foreign governments may pass laws or regulations limiting metals investments for strategic or other policy reasons; and increased environmental or labor costs may depress the value of metals and mining investments. Mid-Capitalization Securities Risk: The securities of mid-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of mid-sized companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of mid-sized issuers may be illiquid or may be restricted as to resale, and their values may be volatile. Money Market Fund Investment Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. Natural Resources Risk: Investments in companies in natural resources industries can be significantly affected by (often rapid) changes in supply of, or demand for, various natural resources. They may also be affected by changes in energy prices, international political and economic developments, environmental incidents, energy conservation, the success of exploration projects, changes in commodity prices, and tax and other government regulations. Non-U.S. Securities Risk: Non-U.S. securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading markets. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Real Estate Sector Risk: An investment in a real property company may be subject to risks similar to those associated with direct ownership of real estate, including, by way of example, the possibility of declines in the value of real estate, losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, environmental liability, zoning laws, regulatory limitations on rents, property taxes, and operating expenses. Some real property companies have limited diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. REIT Risk: REITs are subject to the risks associated with investing in the real estate sector in general. In particular, a REIT may be affected by changes in the values of the properties that the REIT owns or operates or that underlie the mortgages or similar real estate interests in which the REIT invests. In addition, REITs may be affected by changes to interest rates or property taxes. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. In addition, a REIT could fail to qualify for favorable tax or regulatory treatment. Smaller capitalization REITs may be more volatile and may involve more risk than larger capitalization REITs. Equity REITs earn income from leasing properties and realize gains and losses from the sale of properties, and are therefore subject to the risk of extended vacancies, limitations on rents, the failure to collect rents, and the costs of obtaining financing for purchasing real estate. Small-Capitalization Securities Risk: The securities of small-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of smaller companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of smaller issuers may be illiquid or may be restricted as to resale, and their values may have significant volatility. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. Returns on investments in securities of small-capitalization companies could trail the returns on investments in securities of larger companies. Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. Tax Risk-Qualifying Income: Regulated investment companies are subject to favorable tax treatment under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). To qualify as a regulated investment company, the Fund must derive at least 90% of its gross income for each taxable year from sources generating “qualifying income.” Income derived from direct and certain indirect investments in commodities is not qualifying income. Thus, income from the Fund's investments in certain commodities-related investments may cause the Fund not to qualify as a regulated investment company. The Fund may also invest up to 25% of its total assets in one or more QPTPs, including ETPs that are QPTPs and whose principal activities are the buying and selling of commodities or options, futures, or forwards with respect to commodities. Although income from QPTPs is generally qualifying income, if an ETP intending to qualify as a QPTP fails to qualify as a QPTP, the income generated from the Fund's investment in the ETP may not be qualifying income. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. Utilities Sector Risk: Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a regulated utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company's earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company's equipment unusable or obsolete and negatively impact profitability.Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation and the effects of regulatory changes. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Fund Performance The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns for certain time periods compare with the average annual returns of the Bloomberg U.S. Aggregate Bond Index, a broad-based securities index and indexes with characteristics relevant to the Fund.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0020 0 0.0000 0.0020 “Other expenses” have been restated to reflect current fees. Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 20 64 113 255 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 52% of the average value of its portfolio. 0.52 The Fund's Principal Investment Strategy SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) invests, under normal circumstances, at least 80% of the Fund's net assets (plus the amount of borrowings for investment purposes) in a portfolio of U.S. dollar-denominated investment-grade fixed income securities.Investment-grade fixed income securities are instruments that are rated at the time of purchase BBB- or higher by S&P Global Ratings and/or Fitch Ratings Inc., or Baa3 or higher by Moody's Investors Service, Inc., or, if unrated, determined by the management team to be of equivalent quality. The Fund invests in fixed and floating rate securities of varying maturities, such as corporate obligations (including bonds, commercial paper of U.S. and foreign entities, master notes, and medium term notes); government bonds (including U.S. Treasury Bills, notes, and bonds); agency securities; privately-issued securities; asset-backed and mortgage-backed securities; money market instruments (including U.S. and foreign bank time deposits, certificates of deposit, and banker acceptances); and other investment companies. The Fund may invest up to 10% of the Fund's net assets in high yield securities (commonly known as “junk” bonds). The Fund may also invest in exchange traded products (“ETPs”). ETPs include exchange traded funds registered under the Investment Company Act of 1940, as amended (the “1940 Act”) (“Underlying ETFs”) and exchange traded notes (“ETNs”). In addition, the Fund may invest in certain ETPs that pay fees to the Adviser and its affiliates for management, marketing or other services.Under normal circumstances, the effective duration of the Fund is expected to be one year or less. Effective duration is a measure of the Fund's price sensitivity to changes in yields or interest rates; however, investors should be aware that effective duration is not an exact measurement and may not reliably predict a particular security's price sensitivity to changes in yield or interest rates. In addition, under normal circumstances the Fund expects to maintain a weighted average maturity that is two and a half years or less. Weighted average maturity is a U.S. dollar-weighted average of the remaining term to maturity of the underlying securities in the Fund. For the purposes of determining the Fund's weighted average maturity, a security's final maturity date, or for amortizing securities such as asset-backed and mortgage-backed securities, its weighted average life will be used for calculation purposes. The Adviser buys and sells securities for the Fund based on its analysis of credit quality and overall portfolio duration. The Adviser may also use derivative instruments (primarily futures contracts, interest rate and credit default swaps, and options on treasury futures) to manage yield, interest rate exposure (also known as duration), weighted average maturity, and exposure to credit quality. The Fund is not a money market fund and does not seek to maintain a stable net asset value (“NAV”) of $1.00 per share. SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) invests, under normal circumstances, at least 80% of the Fund's net assets (plus the amount of borrowings for investment purposes) in a portfolio of U.S. dollar-denominated investment-grade fixed income securities. Investment-grade fixed income securities are instruments that are rated at the time of purchase BBB- or higher by S&P Global Ratings and/or Fitch Ratings Inc., or Baa3 or higher by Moody's Investors Service, Inc., or, if unrated, determined by the management team to be of equivalent quality. The Adviser buys and sells securities for the Fund based on its analysis of credit quality and overall portfolio duration. As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. Exchange Traded Products Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by the ETPs in which it invests. In addition, the shares of certain ETPs may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the NAV of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an Underlying ETF or market disruptions may cause the market price of the Underlying ETF to deviate from the value of the Underlying ETF's investments, which may be exacerbated in less liquid markets. The value of an ETN may also differ from the valuation of its reference market due to changes in the issuer's credit rating. Affiliated ETP Risk: The Adviser may receive management or other fees from the ETPs (“Affiliated ETPs”) in which the Fund may invest, as well as a management fee for managing the Fund. It is possible that a conflict of interest among the Fund and the Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Fund and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which the Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETPs. In addition, the Adviser may have an incentive to take into account the effect on an Affiliated ETP in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that Affiliated ETP. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general. Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. Financial Sector Risk: Financial services companies are subject to extensive governmental regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate. Futures Contract Risk: A futures contract is a standardized agreement that calls for the purchase or sale of a specific asset at a specific price at a specific future time, or cash settlement of the terms of the contract. Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. Industrial Sector Risk: Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products and services in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, another component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs. Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the NAV of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector. Low Short-Term Interest Rates Risk: During market conditions in which short-term interest rates are at low levels, the Fund's yield can be very low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). During these conditions, it is possible that the Fund will generate an insufficient amount of income to pay its expenses, and will not be able to pay its scheduled dividend. Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results. Money Market Fund Investment Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. Mortgage-Related and Other Asset-Backed Securities Risk: Investments in mortgage-related and other asset-backed securities are subject to the risk of significant credit downgrades, illiquidity, and defaults to a greater extent than many other types of fixed-income investments. The liquidity of mortgage-related and asset-backed securities may change over time. During periods of falling interest rates, mortgage- and asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of mortgage- and asset-backed securities may extend, which may lock in a below-market interest rate, increase the security's duration and interest rate sensitivity, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, and the underlying assets or collateral may be insufficient if the issuer defaults. Non-Diversification Risk: As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of Fund Shares may be more volatile than the values of shares of more diversified funds. Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries may institute negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity. Options Risk: The Fund's successful use of options depends on the ability of the Adviser to forecast market movements correctly. When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option's expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. The effective use of options also depends on the Fund's ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. The sale of options by the Fund may create investment leverage. Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. Swaps Risk: A swap is a two-party contract that generally obligates the parties to exchange payments based on a specified reference security, basket of securities, security index or index component. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty's defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks. U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. Valuation Risk: Certain portfolio holdings may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. Fund Performance The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns for certain time periods compare with the average annual returns of the Bloomberg U.S. Aggregate Bond Index, a broad-based securities index, and an index with characteristics relevant to the Fund.

Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment): 0.0070 0 0.0000 0.0070 Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 72 224 390 871 Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 176% of the average value of its portfolio. 1.76 The Fund's Principal Investment Strategy The Fund primarily invests its assets in securities of other exchange-traded funds (“ETFs”) and common stocks of individual U.S. companies. In particular, the Fund allocates its assets among (i) ETFs that each focus on common stocks of companies included in an individual sector of the S&P 500® Index, as determined by the Global Industry Classification Standard (GICS®) (each, an “Equity Sector” and collectively, the “Equity Sectors”) (each such ETF, an “Equity Sector ETF”) and (ii) common stocks of companies included in the Equity Sectors (“Equity Sector Common Stocks”). As of the date of this Prospectus, the Equity Sectors include: communication services, consumer discretionary, consumer staples, energy, financials, health care, industrials, materials, real estate, information technology and utilities. Components of the S&P 500 Index, and the sector classifications as determined by GICS, are subject to change and are not controlled by the Fund or the Adviser.SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”), the Fund's investment adviser, allocates the Fund's investment exposures among the Equity Sectors based on a proprietary sector selection model. The sector selection model first incorporates macroeconomic, financial and market data to arrive at a projected return forecast for each Equity Sector. Using these projected return forecasts, the model then allocates the weightings of each Equity Sector to construct a target Equity Sector allocation (the “Target Equity Sector Allocation”) that seeks to maximize expected return. The portfolio's final sector allocation is subject to the Adviser's risk and diversification constraints, which limit the amount an Equity Sector may represent in the portfolio. The Adviser may not fully implement the results of the sector selection model if it believes the model does not take into account all relevant data, or that a different evaluation or weighting of the data is more appropriate. It is possible the Fund may not have exposure to all Equity Sectors at all times. The Adviser obtains exposure to specific Equity Sectors by allocating assets primarily among the corresponding Equity Sector ETFs and/or Equity Sector Common Stocks based on a proprietary optimization-based portfolio construction process designed to limit the variance between (i) the return of the Fund's investments and (ii) the return of the Target Equity Sector Allocation.The Adviser typically rebalances the Fund's portfolio on a monthly basis, although rebalancing may occur more frequently depending on market conditions. The Adviser buys and sells securities for the Fund at each rebalancing based on the results of the process described above. As a result of frequent rebalances, the Fund may experience a high turnover rate.Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investments purposes) directly or indirectly through the underlying ETFs, in securities of U.S. companies. The Fund may invest in ETFs that pay fees to the Adviser and its affiliates for management, marketing or other services.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investments purposes) directly or indirectly through the underlying ETFs, in securities of U.S. companies. As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time. Asset Allocation Risk: The Fund's investment performance depends upon the successful allocation by the Adviser of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser's allocation techniques and decisions will produce the desired results. Modeling Risk: The Adviser uses quantitative models in an effort to enhance returns and manage risk. Any imperfections, errors or limitations in these models could limit any benefit to the Fund from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those expected or desired by the Adviser. There can be no assurance that the models will behave as expected in all market conditions. In addition, computer programming used to create quantitative models, or the data on which such models operate, might contain one or more errors. Exchange-Traded Funds Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by an underlying ETF in which it invests. In addition, the shares of an underlying ETF may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value (“NAV”) of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of the underlying ETF's investments, which may be exacerbated in less liquid markets. Affiliated ETF Risk: To the extent the Fund invests in an affiliated underlying ETF, the Fund's investment performance and risks may be directly related to the investment performance and risks of the affiliated ETF. In addition, the Adviser may have an incentive to take into account the effect on an affiliated ETF in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that affiliated ETF. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund. Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines. Communication Services Sector Risk: Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company's profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Consumer Discretionary Sector Risk: The success of consumer product manufacturers and retailers is tied closely to the performance of the overall global economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on their respective profitability. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace. Consumer Staples Sector Risk: Consumer staples companies are subject to government regulation affecting their products which may negatively impact such companies' performance. For instance, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food, beverage, household and personal product companies may be strongly affected by consumer interest, marketing campaigns and other factors affecting supply and demand, including performance of the overall domestic and global economy, interest rates, competition and consumer confidence and spending. Energy Sector Risk: Issuers in energy-related industries can be significantly affected by fluctuations in energy prices and supply and demand of energy fuels. Markets for various energy-related commodities can have significant volatility, and are subject to control or manipulation by large producers or purchasers. Companies in the energy sector may need to make substantial expenditures, and to incur significant amounts of debt, in order to maintain or expand their reserves. Oil and gas exploration and production can be significantly affected by natural disasters as well as changes in exchange rates, interest rates, government regulation, world events and economic conditions. These companies may be at risk for environmental damage claims. Financial Sector Risk: Financial services companies are subject to extensive governmental regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate. Health Care Sector Risk: Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of health care through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market. Industrial Sector Risk: Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products and services in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, another component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs. Large-Capitalization Securities Risk: Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. Larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial, or other market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies. Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results. Materials Sector Risk: Many materials companies are significantly affected by the level and volatility of commodity prices, exchange rates, import controls, worldwide competition, environmental policies and consumer demand. At times, worldwide production of industrial materials has exceeded demand as a result of over-building or economic downturns, leading to poor investment returns or losses. Other risks may include liabilities for environmental damage and general civil liabilities, depletion of resources, and mandated expenditures for safety and pollution control. The materials sector may also be affected by economic cycles, technical progress, labor relations, and government regulations. Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed to individuals as ordinary income. Real Estate Sector Risk: An investment in a real property company may be subject to risks similar to those associated with direct ownership of real estate, including, by way of example, the possibility of declines in the value of real estate, losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, environmental liability, zoning laws, regulatory limitations on rents, property taxes, and operating expenses. Some real property companies have limited diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. Technology Sector Risk: Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a major effect on the value of the Fund's investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. Utilities Sector Risk: Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a regulated utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company's earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company's equipment unusable or obsolete and negatively impact profitability.Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation and the effects of regulatory changes.
