Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 for the time periods indicated and then redeem all of your Shares at the end of those periods. Expenses assuming no redemption are also shown. The Example also assumes that your investment has a 5% return each year and that operating expenses (excluding any sales loads on reinvested dividends, fee waivers and/or expense reimbursements) are as shown in the table above and remain the same. The expenses used to calculate the Fund’s examples do not include fee waivers or expense reimbursements. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

Share Class	1 Year	3 Years	5 Years	10 Years
A:
Expenses assuming redemption	$545	$745	$962	$1,586
Expenses assuming no redemption	$545	$745	$962	$1,586
B:
Expenses assuming redemption	$725	$942	$1,133	$1,831
Expenses assuming no redemption	$175	$542	$933	$1,831
C:
Expenses assuming redemption	$275	$542	$933	$1,831
Expenses assuming no redemption	$175	$542	$933	$1,831
IS:
Expenses assuming redemption	$74	$230	$401	$894
Expenses assuming no redemption	$74	$230	$401	$894

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 274% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund seeks to provide current income. Under normal market conditions, the Fund invests primarily in a diversified portfolio of U.S. government securities, including mortgage-backed securities (MBS) of investment-grade quality, and seeks to provide returns consistent with investments in the market for U.S. home mortgages. The Fund will invest in MBS that are issued or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises (GSEs). The Fund may invest in non-agency MBS, which are those not issued or guaranteed by GSEs. The Fund also may invest in asset-backed securities, other U.S. government securities and certain derivative instruments.

The Fund typically seeks to maintain an overall average dollar-weighted portfolio duration that is within one year above or below the Bloomberg US Mortgage Backed Securities Index (the “Index”). At times, the Fund’s investment adviser’s (the “Adviser”) calculation of portfolio duration may result in variances outside this range. Duration is a measure of the price volatility of a fixed-income security as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected fixed interest and principal payments. The Adviser seeks to create a portfolio, consisting of MBS, derivative instruments and other securities, that outperforms the Index.

Based on fundamental analysis, the Adviser will consider a variety of factors when making decisions to purchase or sell particular securities or derivative contracts. The Fund may, but is not required to, use derivative instruments, which are instruments that have a value based on another instrument, exchange rate or index, and may be used as substitutes for securities in which the Fund can invest, or to hedge against a potential loss in the underlying asset. There can be no assurance that the Fund’s use of derivative instruments will work as intended. Derivative investments made by the Fund are included within the Fund’s 80% policy (as described below) and are calculated at market value.

The Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in U.S. government securities. The Fund will notify shareholders at least 60 days in advance of any change in its investment policy that would enable the Fund to invest, under normal circumstances, less than 80% of its net assets (plus any borrowings for investment purposes) in U.S. government securities.

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

◾ MBS Risk. A rise in interest rates may cause the value of MBS held by the Fund to decline. Certain MBS issued by GSEs are not backed by the full faith and credit of the U.S. government. A non-agency MBS is subject to the risk that the value of such security will decline, because the security is not

issued or guaranteed as to principal or interest by the U.S. government or a GSE. The Fund’s investments in collateralized mortgage obligations (CMOs) may entail greater market, prepayment and liquidity risks than other MBS.

◾ Asset-Backed Securities (ABS) Risk. The value of asset-backed securities (ABS) may be affected by certain factors such as interest rate risk, credit risk, prepayment risk and the availability of information concerning the pool of underlying assets and its structure. Under certain market conditions, ABS may be less liquid and may be difficult to value. Movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain types of ABS. ABS can also be subject to the risk of default on the underlying assets.

◾ Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. The longer the duration of a fixed-income security, the more susceptible it is to interest-rate risk. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.

◾ Credit Risk. It is possible that borrowers of non-agency MBS in which the Fund invests will fail to pay interest or principal on these securities when due, which would result in the Fund losing money.

◾ Counterparty Risk. Counterparty risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

◾ Prepayment and Extension Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the prices of MBS may not rise to as great an extent as those of other fixed-income securities due to the potential prepayment of higher interest mortgages. When interest rates rise, homeowners are less likely to prepay their mortgages. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security, and the price of mortgage-backed securities may decrease more than the price of other fixed income securities when interest rates rise.

◾ Risk of Security Downgrades. The downgrade of the credit of a security held by the Fund may decrease its value. Fixed-income securities with lower ratings tend to have a higher probability that a borrower will default or fail to meet its payment obligations.

◾ Liquidity Risk. The non-agency MBS and CMOs in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.

◾ Leverage Risk. Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

◾ Risk of Investing in Derivative Instruments. The Fund’s exposure to derivative contracts (either directly or through its investment in another investment company) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. The use of derivatives can lead to losses because of adverse movements in the price or value of the asset, index, rate or instrument underlying a derivative, due to failure of a counterparty, or the failure of the counterparty to meet its obligations under the contract, or due to tax or regulatory constraints. Derivatives may create investment leverage in the Fund, which magnifies the Fund’s exposure to the underlying investment. Derivative instruments may be difficult to value, may be illiquid and may be subject to wide swings in valuation caused by changes in the value of the underlying instrument. Over-the-counter derivative contracts generally carry greater liquidity risk than exchange-traded contracts. The loss on derivative transactions may substantially exceed the initial investment.

◾ Asset Segregation Risk. The requirement to secure its obligations in connection with certain transactions, including derivatives or other transactions that expose it to an obligation of another party, by owning underlying assets, entering into offsetting transactions or setting aside cash or liquid assets, may cause the Fund to miss favorable trading opportunities, or to realize losses on such offsetting transactions.

◾ Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Economic, political and financial conditions, industry or economic trends and developments or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, cause the Fund to experience volatility, illiquidity, shareholder redemptions, or other potentially adverse effects. Among other investments, lower-grade bonds may be particularly sensitive to changes in the economy.

◾ Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective and strategy described in this Prospectus. For example, proprietary and third party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

The total returns shown in the bar chart for the Fund’s A class do not reflect the payment of any sales charges or recurring shareholder account fees. If these charges or fees had been included, the returns shown would have been lower.

The Fund’s A class total return for the three-month period from January 1, 2022 to March 31, 2022, was (5.00)%.

Within the periods shown in the bar chart, the Fund’s A class highest quarterly return was 2.20% (quarter ended March 31, 2020). Its lowest quarterly return was (2.21)% (quarter ended June 30, 2013).

Average Annual Total Return Table

The Fund’s IS class commenced operations on May 28, 2020. For the periods prior to commencement of operations of the Fund’s IS class, the performance information shown below is for the Fund’s A class. The performance of the A class has not been adjusted to reflect the expenses of the IS class since the IS class has a lower expense ratio than the A class. The performance shown in the table has been adjusted to reflect differences between the sales loads and charges imposed on the purchase and redemption of the Fund’s A class and IS class. In addition to Return Before Taxes, Return After Taxes is shown for the Fund’s A class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for the A class, and after-tax returns for the B, C and IS classes will differ from those shown for the A class. Actual after-tax returns

depend on each investor’s personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding Shares through tax-deferred programs, such as a 401(k) plan, an Individual Retirement Account or other tax-advantaged investment plans.
