Principal Investment Strategies

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a diversified portfolio of high-yield bonds. For purposes of this 80% policy, high-yield bonds (sometimes referred to as “high-yield securities” or “junk bonds”) include, without limitation, bonds, debt instruments, and other fixed income and income-producing debt instruments, of any kind, issued or guaranteed by governmental or private-sector entities that are rated below investment grade by one or more nationally recognized statistical rating organizations (“NRSROs”) (e.g., rated Ba1 or below by Moody’s Ratings, or BB+ or below by S&P Global Ratings or Fitch Ratings, Inc.) or, if unrated, determined by the Fund to be of comparable quality. High-yield bonds are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal. Split rated debt instruments (debt instruments that receive different ratings from two or more NRSROs) are valued as follows: if three NRSROs rate a debt instrument, the debt instrument will be considered to have the median credit rating; if two of the three NRSROs rate a debt instrument, the debt instrument will be considered to have the lower credit rating of the two provided. High-yield bonds include, but are not limited to: bank loans; payment-in-kind securities; fixed and variable floating rate and deferred interest debt obligations; convertible securities; zero-coupon bonds and debt obligations provided they meet the criteria for below investment grade set forth above. In evaluating the quality of a particular high-yield bond for investment by the Fund, the sub-adviser (the “Sub-Adviser”) does not rely exclusively on credit ratings assigned by NRSROs. The Sub-Adviser will utilize a security’s credit rating as simply one indication of an issuer’s creditworthiness and will principally rely upon its own analysis of any security. The Sub-Adviser does not have restrictions on the rating level of the securities held in the Fund and may purchase and hold securities in default. There are no restrictions on the average maturity of the Fund’s portfolio or the maturity of any single investment. Maturities may vary widely depending on the Sub-Adviser’s assessment of interest rate trends and other economic or market factors. Any remaining assets may be invested in debt instruments rated investment grade; common and preferred stocks; U.S. government securities; money market instruments; and debt instruments of foreign (non-U.S.) issuers, including securities of companies in emerging markets. The Fund may invest in derivatives, including structured debt instruments, dollar roll transactions, swap agreements, including credit default swaps and interest rate swaps, and options on swap agreements. The Fund typically uses derivatives to reduce exposure to other risks, such as interest rate or currency risk, to substitute for taking a position in the underlying asset, and/or to enhance returns in the Fund. The Fund may invest in companies of any market capitalization size. The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. In choosing investments for the Fund, the Sub-Adviser combines extensive company and industry research with relative value analysis to identify high-yield bonds expected to provide above-average returns. Relative value analysis is intended to enhance returns by moving from overvalued to undervalued sectors of the bond market. The Sub-Adviser’s approach to decision making includes contributions from individual portfolio managers responsible for specific industry sectors. In evaluating investments for the Fund, the Sub-Adviser takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment. Among the factors considered, the Sub-Adviser expects typically to take into account environmental, social, and governance (“ESG”) factors to determine whether one or more factors may have a material effect. In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer’s ESG standing, when available. ESG factors will be only one of many considerations in the Sub-Adviser’s evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in an issuer, if at all, will depend on the analysis and judgment of the Sub-Adviser.The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising. The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.

For purposes of this 80% policy, high-yield bonds (sometimes referred to as “high-yield securities” or “junk bonds”) include, without limitation, bonds, debt instruments, and other fixed income and income-producing debt instruments, of any kind, issued or guaranteed by governmental or private-sector entities that are rated below investment grade by one or more nationally recognized statistical rating organizations (“NRSROs”) (e.g., rated Ba1 or below by Moody’s Ratings, or BB+ or below by S&P Global Ratings or Fitch Ratings, Inc.) or, if unrated, determined by the Fund to be of comparable quality. High-yield bonds are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal.

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of bonds. For purposes of this 80% policy, bonds include, without limitation, bonds, debt instruments, and other fixed income and income-producing debt instruments, of any kind, issued or guaranteed by governmental or private-sector entities.The Fund invests primarily in debt instruments rated investment grade, including, but not limited to, corporate, government and mortgage bonds. Investment grade refers to ratings given by nationally recognized statistical rating organizations (“NRSROs”) (e.g., rated Baa3 or above by Moody’s Ratings (“Moody’s”), or BBB- or above by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”)) or, if unrated, determined by the Fund to be of comparable quality. Although the Fund may invest a portion of its assets in debt instruments rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”), the Fund will seek to maintain a minimum weighted average portfolio quality rating of at least investment grade. Below investment grade refers to ratings given by NRSROs (e.g., rated Ba1 or below by Moody’s, or BB+ or below by S&P or Fitch) or, if unrated, determined by the Fund to be of comparable quality. Below investment grade debt instruments are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal. Split rated debt instruments (debt instruments that receive different ratings from two or more NRSROs) are valued as follows: if three NRSROs rate a debt instrument, the debt instrument will be considered to have the median credit rating; if two of the three NRSROs rate a debt instrument, the debt instrument will be considered to have the lower credit rating of the two provided. The dollar-weighted average duration of the Fund will generally range between three and ten years. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the debt instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the debt instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%. The Fund may also invest in: preferred stock; high quality money market instruments; municipal bonds; debt instruments of foreign (non-U.S.) issuers (including those located in emerging market countries); securities denominated in foreign (non-U.S.) currencies; foreign (non-U.S.) currencies; mortgage-backed and asset-backed securities; bank loans and floating rate secured loans (“Senior Loans”); and derivatives including futures, options, and swaps (including credit default swaps, interest rate swaps and total return swaps) involving securities, securities indices and interest rates, which may be denominated in the U.S. dollar or foreign (non-U.S.) currencies. The Fund typically uses derivatives to reduce exposure to other risks, such as interest rate or currency risk, to substitute for taking a position in the underlying asset, and/or to enhance returns in the Fund. The Fund may seek to obtain exposure to the securities in which it invests by entering into a series of purchase and sale contracts or through other investment techniques such as buy backs and dollar rolls. Buy backs and dollar rolls involve selling securities and simultaneously entering into a commitment to purchase those or similar securities on a specified future date and price from the same party. The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. The sub-adviser (the “Sub-Adviser”) believes that relationships between the drivers of debt instrument returns change over time and that recognizing this is key to managing such assets. Therefore, the Sub-Adviser employs a dynamic investment process that seeks to balance top-down macro economic considerations and fundamental bottom-up analysis during the steps of its investment process - sector allocation, security selection, duration, and yield curve management. This includes utilizing proprietary qualitative analysis along with quantitative tools throughout the portfolio construction process. In evaluating investments for the Fund, the Sub-Adviser takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment.

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a diversified portfolio of bonds or derivative instruments having economic characteristics similar to bonds. For purposes of this 80% policy, bonds include, without limitation, bonds, debt instruments, and other fixed income and income-producing debt instruments, of any kind, issued or guaranteed by governmental or private-sector entities. Under normal circumstances, the average dollar-weighted duration of the Fund will not exceed 3 years. Because of the Fund's holdings in amortizing and/or sinking fund securities such as, but not exclusively, asset-backed, commercial mortgage-backed, residential mortgage-backed, collateralized loan obligations (“CLOs”), and corporate bonds, the Fund's average dollar-weighted duration is equivalent to the average weighted duration of the cash flows in the securities held by the Fund given certain prepayment assumptions. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the debt instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the debt instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%. The Fund invests in non-government issued debt instruments, issued by companies of all sizes, rated investment grade, but may also invest up to 20% of its total assets in securities rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”). Below investment grade refers to ratings given by nationally recognized statistical rating organizations (“NRSROs”) (e.g., rated Ba1 or below by Moody’s Ratings (“Moody’s”), or BB+ or below by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”)) or, if unrated, determined by the Fund to be of comparable quality. Below investment grade debt instruments are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal. Split rated debt instruments (debt instruments that receive different ratings from two or more NRSROs) are valued as follows: if three NRSROs rate a debt instrument, the debt instrument will be considered to have the median credit rating; if two of the three NRSROs rate a debt instrument, the debt instrument will be considered to have the lower credit rating of the two provided. Money market securities must be rated in the two highest tiers by Moody’s (P-1 or P-2), S&P (A-1+, A-1, or A-2), or Fitch (F-1+, F-1, or F-2) or, if unrated, determined by the Fund to be of comparable quality. The Fund may also invest in: preferred stocks; U.S. government securities, securities of foreign (non-U.S.) governments, and supranational organizations; mortgage-backed and asset-backed debt instruments; bank loans and floating rate secured loans; municipal bonds, notes, and commercial paper; and debt instruments of foreign (non-U.S.) issuers. The Fund may engage in dollar roll transactions and swap agreements, including credit default swaps, interest rate swaps, and total return swaps. The Fund may use options, options on swap agreements and futures contracts involving securities, securities indices and interest rates to hedge against market risk, to enhance returns, and as a substitute for taking a position in the underlying asset. In addition, private placements of debt instruments (which are often restricted securities) are eligible for purchase along with other illiquid securities. The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder.

Principal Investment Strategies

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in debt securities issued by public and private companies, which are rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”), in preferred stock rated below investment grade, and in derivatives and other synthetic instruments that have economic characteristics similar to such debt securities and preferred stock. For purposes of this 80% policy, below investment grade refers to ratings by one or more nationally recognized statistical rating organizations (“NRSROs”) (e.g., rated Ba1 or below by Moody’s Ratings, or BB+ or below by S&P Global Ratings or Fitch Ratings, Inc.) or, if unrated, determined by the Fund to be of comparable quality. Below investment grade debt securities are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal. Split rated debt instruments (debt instruments that receive different ratings from two or more NRSROs) are valued as follows: if three NRSROs rate a debt instrument, the debt instrument will be considered to have the median credit rating; if two of the three NRSROs rate a debt instrument, the debt instrument will be considered to have the lower credit rating of the two provided. The Fund principally invests in high-yield securities and bank loans, seeking to generate investment income while protecting from adverse market conditions and prioritizing capital preservation. The Fund may invest up to 10% of its net assets in securities rated CCC or below (or the equivalent) by an NRSRO or, if unrated, determined by the Fund to be of comparable quality. The Fund may invest up to 20% of its assets in bank loans and floating rate secured loans, which may be included among the Fund’s high-yield securities for purposes of the 80% policy described above. The Fund may also invest in U.S. Treasury securities and in securities issued by other agencies and instrumentalities of the U.S. government. The sub-adviser (the “Sub-Adviser”) applies a disciplined investment approach, making use of fundamental research, to construct the Fund’s portfolio. The Sub-Adviser’s fundamental research process includes: analysis of a company and its growth by division and region, including revenue model analysis; profit margin analysis; evaluation of the experience and quality of a company’s management team; industry dynamics and competitive analysis; distribution channel and supply chain analysis; and analysis of the macroeconomic climate. In selecting specific debt instruments for investment, the Sub-Adviser may consider such factors as the issuer’s creditworthiness, the investment’s yield in relation to its credit quality and the investment’s relative value in relation to the high yield market. The Sub-Adviser seeks to construct a portfolio with lower volatility than the broader high yield market in part through the Fund’s approach to duration and credit quality. The Fund will maintain an average duration of less than three years. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates.

For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%. The derivatives in which the Fund may invest include, without limitation, credit default swaps, interest rate swaps, and futures contracts. The Fund would typically expect to use derivatives to hedge against interest rate or credit risk, as a substitute for direct investments in securities or other instruments, or to otherwise enhance return. Derivatives transactions may have the effect of either magnifying or limiting the Fund’s gains and losses. The Fund may invest up to 20% of its assets in foreign (non-U.S.) securities, which will typically be U.S. dollar-denominated but may include securities denominated in foreign currencies. The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder.

Under normal circumstances, the Fund invests in debt instruments, including securities rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”) and securities rated investment grade. The Fund may invest in securities rated below investment grade without limit. Below investment grade refers to ratings given by nationally recognized statistical rating organizations (e.g., rated Ba1 or below by Moody’s Ratings, or BB+ or below by S&P Global Ratings or Fitch Ratings, Inc.) or, if unrated, determined by the Fund to be of comparable quality. Below investment grade debt instruments are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal. Split rated debt instruments (debt instruments that receive different ratings from two or more NRSROs) are valued as follows: if three NRSROs rate a debt instrument, the debt instrument will be considered to have the median credit rating; if two of the three NRSROs rate a debt instrument, the debt instrument will be considered to have the lower credit rating of the two provided. The Fund may also invest in floating rate loans and other floating rate debt instruments. The Fund is not managed relative to an index and instead seeks to produce positive returns across varying market conditions. To seek this goal, the Fund has flexibility to invest across a broad range of debt instruments and derivatives. The Fund generally maintains a dollar-weighted average duration profile between -2 and 6 years. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates.

Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%. Debt instruments may include, without limitation, instruments issued by various U.S. and foreign (non-U.S.) (including those located in emerging market countries) public- or private-sector entities, bonds, debentures, notes, convertible securities, commercial paper, loans and related assignments and participations, corporate debt, asset- and mortgage-backed securities, preferred stock, bank certificates of deposit, fixed time deposits, bankers' acceptances and money market instruments, including money market funds denominated in U.S. dollars or foreign (non-U.S.) currencies. Floating rate loans and other floating rate debt instruments include floating rate bonds, floating rate notes, floating rate debentures, and tranches of floating rate asset-backed securities, including structured notes, made to, or issued by, U.S. and foreign (non-U.S.) corporations or other business entities. The Fund may also invest in inflation-indexed bonds of varying maturities issued by the U.S. and foreign (non-U.S.) governments, their agencies and instrumentalities, and U.S. and foreign (non-U.S.) corporations. The Fund may also invest in derivatives, including options, futures, swaps (including interest rate swaps, total return swaps, and credit default swaps), and currency forwards, as a substitute for taking a position in an underlying asset, to make tactical asset allocations, to seek to minimize risk, to enhance returns, and/or assist in managing cash. In evaluating investments for the Fund, the sub-adviser (the “Sub-Adviser”) takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment. Among the factors considered, the Sub-Adviser expects typically to take into account environmental, social, and governance (“ESG”) factors to determine whether one or more factors may have a material effect. In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer’s ESG standing, when available. ESG factors will be only one of many considerations in the Sub-Adviser’s evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in an issuer, if at all, will depend on the analysis and judgment of the Sub-Adviser.The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising. The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.

Below investment grade refers to ratings given by nationally recognized statistical rating organizations (e.g., rated Ba1 or below by Moody’s Ratings, or BB+ or below by S&P Global Ratings or Fitch Ratings, Inc.) or, if unrated, determined by the Fund to be of comparable quality.

In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer’s ESG standing, when available. ESG factors will be only one of many considerations in the Sub-Adviser’s evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in an issuer, if at all, will depend on the analysis and judgment of the Sub-Adviser.

Principal Investment Strategies

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

The Fund invests at least 99.5% of its total assets in government securities, cash and repurchase agreements collateralized fully by government securities or cash. In addition, under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in government securities and repurchase agreements that are collateralized by government securities. For purposes of the Fund’s 99.5% policy and 80% policy, government securities means any security issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an agency or instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States; or any certificate of deposit for any of the foregoing.The Fund invests in a portfolio of securities maturing in 397 days or less (with certain exceptions) that will have a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. The Fund may invest in variable and floating rate instruments, and transact in securities on a when-issued, delayed delivery, or forward commitment basis. The Fund operates as a “money market fund” and the securities purchased by the Fund are subject to the quality, diversification, and other requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder (the “1940 Act”), and other rules adopted by the U.S. Securities and Exchange Commission (the “SEC”). Fund investments are valued based on the amortized cost valuation method pursuant to Rule 2a-7 under the 1940 Act. The Fund may maintain a rating from one or more rating agencies that provide ratings on money market funds. There can be no assurance that the Fund will maintain any particular rating or maintain it with a particular rating agency. To maintain a rating, the sub-adviser (the “Sub-Adviser”) may manage the Fund more conservatively than if it was not rated. The Fund may invest in other investment companies that are money market funds to the extent permitted under the 1940 Act. In choosing investments for the Fund, the Sub-Adviser employs a disciplined, four-step investment process designed to ensure preservation of capital and liquidity, as well as adherence to regulatory requirements. The four steps are: first, a formal list of approved issuers is actively maintained; second, securities of issuers on the approved list that meet the Fund’s guidelines are selected for investment; third, diversification is continuously monitored to ensure that regulatory limits are not exceeded; and finally, portfolio maturity decisions are made based upon expected cash flows, income opportunities available in the market, and expectations of future interest rates.

For purposes of the Fund’s 99.5% policy and 80% policy, government securities means any security issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an agency or instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States; or any certificate of deposit for any of the foregoing.

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of bonds. For purposes of this 80% policy, bonds include, without limitation, bonds, debt instruments, and other fixed income and income-producing debt instruments, of any kind, issued or guaranteed by governmental or private-sector entities.The Fund invests primarily in debt instruments rated investment grade, including, but not limited to, corporate, government, municipal and mortgage bonds. Investment grade refers to ratings given by nationally recognized statistical rating organizations (“NRSROs”) (e.g., rated Baa3 or above by Moody’s Ratings (“Moody’s”), or BBB- or above by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”)) or, if unrated, determined by the Fund to be of comparable quality. Although the Fund may invest up to 10% of its assets in debt instruments rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”), the Fund will seek to maintain a minimum weighted average portfolio quality rating of at least investment grade. Below investment grade refers to ratings given by all NRSROs (e.g., rated Ba1 or below by Moody’s, or BB+ or below by S&P or Fitch) or, if unrated, determined by the Fund to be of comparable quality. Below investment grade debt instruments are regarded as having more speculative characteristics with respect to the payment of interest and repayment of principal. Split rated debt instruments (debt instruments that receive different ratings from two or more NRSROs) are valued as follows: if three NRSROs rate a debt instrument, the debt instrument will be considered to have the median credit rating; if two of the three NRSROs rate a debt instrument, the debt instrument will be considered to have the lower credit rating of the two provided. The dollar-weighted average duration of the Fund will generally range between three and ten years. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the debt instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the debt instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%. The Fund may also invest in: preferred stock; high quality money market instruments; debt instruments of foreign (non-U.S.) issuers (including those located in emerging market countries); mortgage-backed and asset-backed securities; and derivatives including futures, options, and swaps (including credit default swaps, interest rate swaps and total return swaps) involving securities, securities indices and interest rates, which may be denominated in the U.S. dollar. The Fund typically uses derivatives to reduce exposure to other risks, such as interest rate, to substitute for taking a position in the underlying asset, and/or to enhance returns in the Fund. The Fund may seek to obtain exposure to the securities in which it invests by entering into a series of purchase and sale contracts or through other investment techniques such as buy backs and dollar rolls. Buy backs and dollar rolls involve selling securities and simultaneously entering into a commitment to purchase those or similar securities on a specified future date and price from the same party. The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. The sub-adviser (the “Sub-Adviser”) believes that relationships between the drivers of debt instrument returns change over time and that recognizing this is key to managing such assets. Therefore, the Sub-Adviser employs a dynamic investment process that seeks to balance top-down macro economic considerations and fundamental bottom-up analysis during the steps of its investment process - sector allocation, security selection, duration, and yield curve management. This includes utilizing proprietary qualitative analysis along with quantitative tools throughout the portfolio construction process. In evaluating investments for the Fund, the Sub-Adviser takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment. Among the factors considered, the Sub-Adviser expects typically to take into account environmental, social, and governance (“ESG”) factors to determine whether one or more factors may have a material effect. In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer’s ESG standing, when available. ESG factors will be only one of many considerations in the Sub-Adviser’s evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in an issuer, if at all, will depend on the analysis and judgment of the Sub-Adviser.The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising. The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.
