Angel Oak Multi-Strategy Income Fund
Prospectus [Line Items]
Strategy [Heading]	Principal Investment Strategies
Strategy Narrative [Text Block]	The Fund invests primarily in agency and non-agency residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”), collateralized loan obligations (“CLOs”), collateralized debt obligations (“CDOs”), collateralized mortgage obligations (“CMOs”), collateralized bond obligations (“CBOs”), asset-backed securities (“ABS”), including securities backed by assets such as unsecured consumer loans, credit card receivables, student loans, automobile loans, loans financing solar energy systems, and residential and commercial real estate, and other debt securitizations (collectively, “Structured Products”); mortgage loans, secured and unsecured consumer loans, commercial loans and pools of such loans (collectively, “Loans”); corporate debt, including bank-issued subordinated debt; equity securities of banks, real estate investment trusts, or other issuers; and U.S. Treasury and U.S. government agency securities. The Fund may invest up to 20% of its net assets in CLOs, which are backed by a pool of loans, as well as CDOs, which may be backed by a pool of debt. CLOs and CDOs are similar to CMOs, but differ as to the type of underlying loan or debt. The Fund may invest in the securities of other investment companies, including those that are part of the same group of investment companies as the Fund, that pursue an investment strategy that supports the Fund’s investment objective. The Fund will concentrate its investments in agency and non-agency RMBS and CMBS (collectively, “MBS”). This means that, under normal circumstances, the Fund will invest more than 25% of its total assets in MBS (measured at the time of purchase). The Fund will not concentrate its investments in any other group of industries. The Fund’s policy to concentrate its investments in MBS is fundamental and may not be changed without shareholder approval. The fixed income instruments in which the Fund invests may include those of issuers from the United States and other countries. The Fund’s investments in foreign debt securities will typically be denominated in U.S. dollars. The Fund may invest up to 15% of its net assets in investments that are deemed to be illiquid, which may include private placements, certain Rule 144A securities (which are subject to resale restrictions), and securities of issuers that are bankrupt or in default. The Fund may invest, without limitation, in securities of any maturity and duration. Maturity refers to the length of time until a debt security’s principal is repaid with interest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call and put features and prepayment exposure into one measure with a higher duration indicating greater sensitivity to interest rates. For example, if a portfolio has a duration of two years, and interest rates increase (fall) by 1%, the portfolio would decline (increase) in value by approximately 2%. However, duration may not accurately reflect the true interest rate sensitivity of instruments held by the Fund and, therefore the Fund’s exposure to changes in interest rates. The Fund’s investments in RMBS and ABS will span a broad segment of consumer creditworthiness segments, which will include exposure to prime, near-prime, and subprime consumers. The Fund may invest in high-yield securities and securities that are not rated by any rating agencies. These “high-yield” securities (also known as “junk bonds”) will be rated BB+ or lower by S&P Global Ratings or will be of equivalent quality rating from another Nationally Recognized Statistical Ratings Organization. If a bond is unrated, the Adviser may determine whether it is of comparable quality and therefore eligible for the Fund’s investment. Although the Fund will not acquire investments of issuers that are in default at the time of investment, the Fund may hold such securities if an investment subsequently defaults. The Fund may implement its strategy by making investments directly or through a wholly-owned and controlled subsidiary of the Fund organized as a statutory trust under the laws of the state of Delaware (each, a “Subsidiary”). The Subsidiary may invest in loans, including residential and commercial real estate whole loans, participations in such loans or instruments representing the right to receive interest payments and principal due on such loans. The Subsidiary may invest in residential and commercial real estate loans of any credit rating or no credit rating, including without limit in loans that are rated below investment grade. The principal risks of investments in the Subsidiary are the same as those relating to residential loans and mortgages. The allocation of the Fund’s investments, if any, in the Subsidiary will vary over time, and the Subsidiary’s investments will also vary and may not include all of the types of investments described above. In the future, the Fund may form one or more additional wholly-owned and controlled subsidiaries. In pursuing its investment objectives or for hedging purposes, the Fund may utilize short selling, borrowing and various types of derivative instruments, including swaps, futures contracts, and options, although not all such derivatives will be used at all times. Such derivatives may trade over-the-counter or on an exchange and may principally be used for one or more of the following purposes: speculation, currency hedging, duration management, credit deterioration hedging, hedges against broad market movements, or to pursue the Fund’s investment objective. The Fund may borrow to the maximum extent permitted by applicable law. The Fund may also invest in repurchase agreements and borrow through reverse repurchase agreements. The Fund’s allocation of its assets into various asset classes within its investment strategy will depend on the views of the Adviser as to the best value relative to what is currently presented in the marketplace. Investment decisions are made based on fundamental research and analysis to identify issuers with the ability to improve their credit profile over time with attractive valuations, resulting in both income and potential capital appreciation. In selecting investments, the Adviser may consider maturity, yield and ratings information and opportunities for price appreciation among other criteria. The Adviser also analyzes a variety of factors when selecting investments for the Fund, such as collateral quality, credit support, structure and market conditions. The Adviser attempts to diversify risks that arise from position sizes, geography, ratings, duration, deal structure and collateral values. The Adviser will also seek to invest in securities that have relatively low volatility. The Adviser seeks to limit risk of principal by targeting assets that it considers undervalued. From time to time, the Fund may allocate its assets so as to focus on particular types of securities. As part of its investment process, the Adviser also considers certain environmental, social and governance (“ESG”) and sustainability factors that it believes could have a material impact on certain securities in which the Fund may invest. These determinations may not be conclusive, and securities that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities that may be positively impacted by such factors.

Strategy Narrative [Text Block]	In pursuing its investment objective, the Fund will, under normal circumstances, invest in securities which cause the Fund to have a dollar-weighted average maturity of less than two years and a dollar-weighted average duration of less than one year. The Fund invests primarily in agency and non-agency residential mortgage-backed securities (“RMBS”), asset-backed securities (“ABS”), including securities backed by assets such as credit card receivables, student loans, automobile loans, and residential and commercial real estate, collateralized loan obligations (“CLOs”), collateralized debt obligations (“CDOs”), collateralized mortgage obligations (“CMOs”), and other debt securitizations (collectively, “Structured Products”); corporate debt and other debt securities; and U.S. Treasury and U.S. government agency securities. The Fund may invest up to 30% of its net assets in CLOs. The Fund may invest in the securities of other investment companies (including those that are part of the same group of investment companies as the Fund) that pursue an investment strategy that supports the Fund’s investment objective.

The Fund is not a money market fund and does not seek to maintain a stable net asset value (“NAV”). The Fund may engage in active and frequent trading of its portfolio securities. The Fund may invest, without limitation, in securities of any maturity and duration, but, under normal circumstances, the Fund will have a dollar-weighted average maturity of less than two years and a dollar-weighted average duration of less than one year. Maturity refers to the length of time until a debt security’s principal is repaid with interest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. Duration incorporates a security’s yield, coupon, final maturity, call and put features and prepayment exposure into one measure, with a higher duration indicating greater sensitivity to interest rates.

Strategy Narrative [Text Block]	In pursuing its investment objective, the Fund will, under normal circumstances, invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities rated below investment grade (measured at the time of purchase). These securities may include domestic and foreign corporate debt securities, including bank-issued subordinated debt, fixed and floating rate bonds, and zero coupon bonds; and various forms of debt securitizations, including agency and non-agency residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”); collateralized loan obligations (“CLOs”), collateralized debt obligations (“CDOs”), collateralized mortgage obligations (“CMOs”), asset-backed securities (“ABS”), including securities or securitizations backed by assets such as credit card receivables, student loans, automobile loans, and residential and commercial real estate, and other debt securitizations (“Structured Products”); and derivative instruments that invest substantially all of their assets in, are linked to, or otherwise provide investment exposure to, securities rated below investment grade. The Fund may purchase corporate securities issued by companies of any size – small cap, medium cap or large cap. The Fund may invest, without limitation, in securities of any quality and maturity, including high-yield securities (also known as “junk bonds”), and securities that are not rated by any rating agencies. These high-yield securities will be rated BB+ or lower by S&P Global Ratings or will be of equivalent quality rating from another Nationally Recognized Statistical Ratings Organization. If a security is unrated, the Adviser may determine whether it is of comparable quality and therefore eligible for the Fund’s investment. The Fund intends to focus primarily on securities with credit ratings (or equivalent quality) between the range of BB+ and B- of the high-yield market. However, the Fund may invest in or continue to hold securities that have credit ratings lower than B, are bankrupt, or are in default. The Fund will, under normal circumstances, invest at least 5% of its net assets, plus the amount of any borrowings for investment purposes, in Structured Products. The Fund may also invest up to 20% of its assets in investment grade securities, including U.S. Treasury and U.S. government agency securities. The Fund may invest up to 15% of its net assets in equity securities such as common stock, preferred stock, warrants, rights and exchange-traded funds (“ETFs”) that invest in equity securities or that track an index of equity securities. The Fund may invest, without limitation, in the securities of other investment companies, including closed-end investment companies, ETFs or business development companies (“BDCs”). The other investment companies in which the Fund invests may be part of the same group of investment companies as the Fund. The Fund may invest up to 25% of its assets in foreign debt securities, including corporate fixed income securities registered and sold in the United States by foreign issuers (commonly known as “Yankee” bonds). The Fund may invest up to 15% of its net assets in investments that are deemed to be illiquid, which may include private placements, certain Rule 144A securities (which are subject to resale restrictions), and securities of issuers that are bankrupt or in default. The Fund may invest, without limitation, in securities of any maturity and duration, but, under normal circumstances, the Fund will have a dollar-weighted average maturity between two and fifteen years. The average maturity may be less than two years if the Adviser believes a temporary defensive posture is appropriate. Maturity refers to the length of time until a debt security’s principal is repaid with interest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call and put features and prepayment exposure into one measure with a higher duration indicating greater sensitivity to interest rates.

The Fund may borrow to the maximum extent permitted by applicable law. The Fund may also invest in repurchase agreements and borrow through reverse repurchase agreements. The Fund’s allocation of its assets into various asset classes within its investment strategy will depend on the views of the Adviser as to the best value relative to what is currently presented in the marketplace. Within the Structured Products allocation, the Adviser analyzes a variety of factors when selecting investments for the Fund, such as collateral quality, credit support, structure and market conditions. Within the corporate credit allocation, investment decisions are made based on fundamental research and analysis to identify issuers with the ability to improve their credit profile over time with attractive valuations, resulting in both income and potential capital appreciation. Across all allocations, the Adviser may consider maturity, yield and ratings information and opportunities for price appreciation among other criteria. The Adviser attempts to diversify risks that arise from position sizes, geography, ratings, duration, deal structure and collateral values. The Adviser seeks to limit risk of principal by targeting assets that it considers undervalued. From time to time, the Fund may allocate its assets so as to focus on particular types of securities.

Strategy Narrative [Text Block]	The Fund will, under normal circumstances, invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in mortgage-backed securities (“MBS”). For purposes of this 80% investment policy, the Adviser will select the Fund’s investments in mortgage-backed securities within a range of instruments across various asset classes, including: agency and non- agency residential mortgage-backed securities (“RMBS”), agency and non-agency commercial mortgage-backed securities (“CMBS”), collateralized debt obligations (“CDOs”) that include a significant majority of residential or commercial mortgages; and collateralized mortgage obligations (“CMOs”). The Fund may invest up to 20% of its net assets in a variety of asset classes, including: asset-backed securities (“ABS”), including securities or securitizations backed by assets such as credit card receivables, student loans, automobile loans, and residential and commercial real estate, and other debt securitizations (collectively with CDOs and CMOs, “Structured Products”); secured and unsecured consumer loans, commercial loans and pools of such loans (collectively, “Loans”); corporate debt, including bank-issued subordinated debt; municipal securities; U.S. Treasury and U.S. government agency securities; and derivative instruments that invest substantially all of their assets in, are linked to, or otherwise provide investment exposure to, bonds. The Fund may invest in the securities of other investment companies, including closed-end investment companies, exchange-traded funds (“ETFs”) or business development companies (“BDCs”). The other investment companies in which the Fund invests may be part of the same group of investment companies as the Fund. The Fund will concentrate its investments in agency and non-agency RMBS and CMBS and mortgage loans (“Mortgage Related Instruments”), which are credit instruments that are backed by real estate and, consequently, subject to some of the same risks as those associated with the real estate industry. This means that, under normal circumstances, the Fund will invest more than 25% of its assets in Mortgage Related Instruments (measured at the time of purchase). The Fund will not concentrate its investments in any other group of industries. The Fund’s policy to concentrate its investments in Mortgage Related Instruments is fundamental and may not be changed without shareholder approval. The Fund is classified as a non-diversified portfolio under the Investment Company Act of 1940, as amended (the “1940 Act”), meaning it may invest a greater percentage of its assets in a single or limited number of issuers than a diversified fund. The fixed income instruments in which the Fund invests may include those of issuers from the United States and other countries, without limitation. The Fund’s investments in foreign debt securities will typically be denominated in U.S. dollars. The Fund may invest up to 15% of its net assets in investments that are deemed to be illiquid, which may include private placements, certain Rule 144A securities (which are subject to resale restrictions), and securities of issuers that are bankrupt or in default. The Fund may invest in securities of any maturity and duration. Under normal market conditions, the Fund’s target portfolio duration is two to eight years, and the target weighted average maturity of the Fund’s portfolio is two to fifteen years. Maturity refers to the length of time until a debt security’s principal is repaid with interest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. Duration incorporates a security’s yield, coupon, final maturity, call and put features, and prepayment exposure into one measure with a higher duration indicating greater sensitivity to interest rates. For example, if a portfolio has a duration of two years, and interest rates increase (fall) by 1%, the portfolio would decline (increase) in value by approximately 2%. However, duration may not accurately reflect the true interest rate sensitivity of instruments held by the Fund and, therefore the Fund’s exposure to changes in interest rates. The Fund may invest, without limitation, in securities of any quality and maturity, including high-yield securities (also known as “junk bonds”), and securities that are not rated by any rating agencies. Under normal market conditions, the Fund will not invest more than 30% of its total assets in high-yield securities. These high-yield securities will be rated BB+ or lower by S&P Global Ratings or will be of equivalent quality rating from another Nationally Recognized Statistical Ratings Organization (“NRSRO”). If a security is unrated, the Adviser may determine whether it is of comparable quality and therefore eligible for the Fund’s investment. In pursuing its investment objective or for hedging purposes, the Fund may utilize borrowing and various types of derivative instruments, including swaps, futures contracts, and options, although not all such derivatives will be used at all times. Such derivatives may trade over-the-counter or on an exchange and may principally be used for one or more of the following purposes: speculation, currency hedging, duration management, credit deterioration hedging, hedges against broad market movements, or to pursue the Fund’s investment objective. The Fund may borrow to the maximum extent permitted by applicable law. The Fund may also invest in repurchase agreements and borrow through reverse repurchase agreements. The Fund’s allocation of its assets into various asset classes within its investment strategy will depend on the views of the Adviser as to the best value relative to what is currently presented in the marketplace. Investment decisions are made based on fundamental research and analysis to identify issuers with the ability to improve their credit profile over time with attractive valuations, resulting in both income and potential capital appreciation. In selecting investments, including Structured Products, the Adviser may consider maturity, yield and ratings information and opportunities for price appreciation among other criteria. The Adviser also analyzes a variety of factors when selecting investments for the Fund, such as collateral quality, credit support, structure and market conditions. The Adviser attempts to diversify risks that arise from position sizes, geography, ratings, duration, deal structure and collateral values. The Adviser seeks to limit risk of principal by targeting assets that it considers undervalued. As part of its investment process, the Adviser also considers certain environmental, social and governance (“ESG”) and sustainability factors that it believes could have a material impact on certain securities in which the Fund may invest. These determinations may not be conclusive, and securities that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities that may be positively impacted by such factors. The Fund is an actively managed ETF, which is a fund that trades like other publicly-traded securities. The Fund is not an index fund and does not seek to replicate the performance of a specified index.

Investment Strategy

May 31, 2026

Principal Investment Strategies

The Fund invests primarily in agency and non-agency residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”), collateralized loan obligations (“CLOs”), collateralized debt obligations (“CDOs”), collateralized mortgage obligations (“CMOs”), collateralized bond obligations (“CBOs”), asset-backed securities (“ABS”), including securities backed by assets such as unsecured consumer loans, credit card receivables, student loans, automobile loans, loans financing solar energy systems, and residential and commercial real estate, and other debt securitizations (collectively, “Structured Products”); mortgage loans, secured and unsecured consumer loans, commercial loans and pools of such loans (collectively, “Loans”); corporate debt, including bank-issued subordinated debt; equity securities of banks, real estate investment trusts, or other issuers; and U.S. Treasury and U.S. government agency securities.

The Fund may invest up to 20% of its net assets in CLOs, which are backed by a pool of loans, as well as CDOs, which may be backed by a pool of debt. CLOs and CDOs are similar to CMOs, but differ as to the type of underlying loan or debt.

The Fund may invest in the securities of other investment companies, including those that are part of the same group of investment companies as the Fund, that pursue an investment strategy that supports the Fund’s investment objective.

The Fund will concentrate its investments in agency and non-agency RMBS and CMBS (collectively, “MBS”). This means that, under normal circumstances, the Fund will invest more than 25% of its total assets in MBS (measured at the time of purchase). The Fund will not concentrate its investments in any other group of industries. The Fund’s policy to concentrate its investments in MBS is fundamental and may not be changed without shareholder approval.

The fixed income instruments in which the Fund invests may include those of issuers from the United States and other countries. The Fund’s investments in foreign debt securities will typically be denominated in U.S. dollars.

The Fund may invest up to 15% of its net assets in investments that are deemed to be illiquid, which may include private placements, certain Rule 144A securities (which are subject to resale restrictions), and securities of issuers that are bankrupt or in default.

The Fund may invest, without limitation, in securities of any maturity and duration. Maturity refers to the length of time until a debt security’s principal is repaid with interest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call and put features and prepayment exposure into one measure with a higher duration indicating greater sensitivity to interest rates. For example, if a portfolio has a duration of two years, and interest rates increase (fall) by 1%, the portfolio would decline (increase) in value by approximately 2%. However, duration may not accurately reflect the true interest rate sensitivity of instruments held by the Fund and, therefore the Fund’s exposure to changes in interest rates.

The Fund’s investments in RMBS and ABS will span a broad segment of consumer creditworthiness segments, which will include exposure to prime, near-prime, and subprime consumers.

The Fund may invest in high-yield securities and securities that are not rated by any rating agencies. These “high-yield” securities (also known as “junk bonds”) will be rated BB+ or lower by S&P Global Ratings or will be of equivalent quality rating from another Nationally Recognized Statistical Ratings Organization. If a bond is unrated, the Adviser may determine whether it is of comparable quality and therefore eligible for the Fund’s investment. Although the Fund will not acquire investments of issuers that are in default at the time of investment, the Fund may hold such securities if an investment subsequently defaults.

The Fund may implement its strategy by making investments directly or through a wholly-owned and controlled subsidiary of the Fund organized as a statutory trust under the laws of the state of Delaware (each, a “Subsidiary”). The Subsidiary may invest in loans, including residential and commercial real estate whole loans, participations in such loans or instruments representing the right to receive interest payments and principal due on such loans. The Subsidiary may invest in residential and commercial real estate loans of any credit rating or no credit rating, including without limit in loans that are rated below investment grade. The principal risks of investments in the Subsidiary are the same as those relating to residential loans and mortgages. The allocation of the Fund’s investments, if any, in the Subsidiary will vary over time, and the Subsidiary’s investments will also vary and may not include all of the types of investments described above. In the future, the Fund may form one or more additional wholly-owned and controlled subsidiaries.

In pursuing its investment objectives or for hedging purposes, the Fund may utilize short selling, borrowing and various types of derivative instruments, including swaps, futures contracts, and options, although not all such derivatives will be used at all times. Such derivatives may trade over-the-counter or on an exchange and may principally be used for one or more of the following purposes: speculation, currency hedging, duration management, credit deterioration hedging, hedges against broad market movements, or to pursue the Fund’s investment objective. The Fund may borrow to the maximum extent permitted by applicable law. The Fund may also invest in repurchase agreements and borrow through reverse repurchase agreements.

The Fund’s allocation of its assets into various asset classes within its investment strategy will depend on the views of the Adviser as to the best value relative to what is currently presented in the marketplace. Investment decisions are made based on fundamental research and analysis to identify issuers with the ability to improve their credit profile over time with attractive valuations, resulting in both income and potential capital appreciation. In selecting investments, the Adviser may consider maturity, yield and ratings information and opportunities for price appreciation among other criteria. The Adviser also analyzes a variety of factors when selecting investments for the Fund, such as collateral quality, credit support, structure and market conditions. The Adviser attempts to diversify risks that arise from position sizes, geography, ratings, duration, deal structure and collateral values. The Adviser will also seek to invest in securities that have relatively low volatility. The Adviser seeks to limit risk of principal by targeting assets that it considers undervalued. From time to time, the Fund may allocate its assets so as to focus on particular types of securities. As part of its investment process, the Adviser also considers certain environmental, social and governance (“ESG”) and sustainability factors that it believes could have a material impact on certain securities in which the Fund may invest. These determinations may not be conclusive, and securities that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities that may be positively impacted by such factors.

In pursuing its investment objective, the Fund will, under normal circumstances, invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities rated below investment grade (measured at the time of purchase). These securities may include domestic and foreign corporate debt securities, including bank-issued subordinated debt, fixed and floating rate bonds, and zero coupon bonds; and various forms of debt securitizations, including agency and non-agency residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”); collateralized loan obligations (“CLOs”), collateralized debt obligations (“CDOs”), collateralized mortgage obligations (“CMOs”), asset-backed securities (“ABS”), including securities or securitizations backed by assets such as credit card receivables, student loans, automobile loans, and residential and commercial real estate, and other debt securitizations (“Structured Products”); and derivative instruments that invest substantially all of their assets in, are linked to, or otherwise provide investment exposure to, securities rated below investment grade. The Fund may purchase corporate securities issued by companies of any size – small cap, medium cap or large cap.

The Fund may invest, without limitation, in securities of any quality and maturity, including high-yield securities (also known as “junk bonds”), and securities that are not rated by any rating agencies. These high-yield securities will be rated BB+ or lower by S&P Global Ratings or will be of equivalent quality rating from another Nationally Recognized Statistical Ratings Organization. If a security is unrated, the Adviser may determine whether it is of comparable quality and therefore eligible for the Fund’s investment. The Fund intends to focus primarily on securities with credit ratings (or equivalent quality) between the range of BB+ and B- of the

high-yield market. However, the Fund may invest in or continue to hold securities that have credit ratings lower than B, are bankrupt, or are in default.

The Fund will, under normal circumstances, invest at least 5% of its net assets, plus the amount of any borrowings for investment purposes, in Structured Products.

The Fund may also invest up to 20% of its assets in investment grade securities, including U.S. Treasury and U.S. government agency securities.

The Fund may invest up to 15% of its net assets in equity securities such as common stock, preferred stock, warrants, rights and exchange-traded funds (“ETFs”) that invest in equity securities or that track an index of equity securities.

The Fund may invest up to 25% of its assets in foreign debt securities, including corporate fixed income securities registered and sold in the United States by foreign issuers (commonly known as “Yankee” bonds).

The Fund may invest, without limitation, in securities of any maturity and duration, but, under normal circumstances, the Fund will have a dollar-weighted average maturity between two and fifteen years. The average maturity may be less than two years if the Adviser believes a temporary defensive posture is appropriate. Maturity refers to the length of time until a debt security’s principal is repaid with interest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call and put features and prepayment exposure into one measure with a higher duration indicating greater sensitivity to interest rates. For example, if a portfolio has a duration of two years, and interest rates increase (fall) by 1%, the portfolio would decline (increase) in value by approximately 2%. However, duration may not accurately reflect the true interest rate sensitivity of instruments held by the Fund and, therefore the Fund’s exposure to changes in interest rates.

The Fund will, under normal circumstances, invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in mortgage-backed securities (“MBS”). For purposes of this 80% investment policy, the Adviser will select the Fund’s investments in mortgage-backed securities within a range of instruments across various asset classes, including: agency and non-

agency residential mortgage-backed securities (“RMBS”), agency and non-agency commercial mortgage-backed securities (“CMBS”), collateralized debt obligations (“CDOs”) that include a significant majority of residential or commercial mortgages; and collateralized mortgage obligations (“CMOs”).

The Fund may invest up to 20% of its net assets in a variety of asset classes, including: asset-backed securities (“ABS”), including securities or securitizations backed by assets such as credit card receivables, student loans, automobile loans, and residential and commercial real estate, and other debt securitizations (collectively with CDOs and CMOs, “Structured Products”); secured and unsecured consumer loans, commercial loans and pools of such loans (collectively, “Loans”); corporate debt, including bank-issued subordinated debt; municipal securities; U.S. Treasury and U.S. government agency securities; and derivative instruments that invest substantially all of their assets in, are linked to, or otherwise provide investment exposure to, bonds.

The Fund may invest in the securities of other investment companies, including closed-end investment companies, exchange-traded funds (“ETFs”) or business development companies (“BDCs”). The other investment companies in which the Fund invests may be part of the same group of investment companies as the Fund.

The Fund will concentrate its investments in agency and non-agency RMBS and CMBS and mortgage loans (“Mortgage Related Instruments”), which are credit instruments that are backed by real estate and, consequently, subject to some of the same risks as those associated with the real estate industry. This means that, under normal circumstances, the Fund will invest more than 25% of its assets in Mortgage Related Instruments (measured at the time of purchase). The Fund will not concentrate its investments in any other group of industries. The Fund’s policy to concentrate its investments in Mortgage Related Instruments is fundamental and may not be changed without shareholder approval.

The Fund is classified as a non-diversified portfolio under the Investment Company Act of 1940, as amended (the “1940 Act”), meaning it may invest a greater percentage of its assets in a single or limited number of issuers than a diversified fund.

The fixed income instruments in which the Fund invests may include those of issuers from the United States and other countries, without limitation. The Fund’s investments in foreign debt securities will typically be denominated in U.S. dollars.

The Fund may invest in securities of any maturity and duration. Under normal market conditions, the Fund’s target portfolio duration is two to eight years, and the target weighted average maturity of the Fund’s portfolio is two to fifteen years. Maturity refers to the length of time until a debt security’s principal is repaid with interest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. Duration incorporates a security’s yield, coupon, final maturity, call and put features, and prepayment exposure into one measure with a higher duration indicating greater sensitivity to interest rates. For example, if a portfolio has a duration of two years, and interest rates increase (fall) by 1%, the portfolio would decline (increase) in value by approximately 2%. However, duration may not accurately reflect the true interest rate sensitivity of instruments held by the Fund and, therefore the Fund’s exposure to changes in interest rates.

The Fund may invest, without limitation, in securities of any quality and maturity, including high-yield securities (also known as “junk bonds”), and securities that are not rated by any rating agencies. Under normal market conditions, the Fund will not invest more than 30% of its total assets in high-yield securities. These high-yield securities will be rated BB+ or lower by S&P Global Ratings or will be of equivalent quality rating from another Nationally Recognized Statistical Ratings Organization (“NRSRO”). If a security is unrated, the Adviser may determine whether it is of comparable quality and therefore eligible for the Fund’s investment.

In pursuing its investment objective or for hedging purposes, the Fund may utilize borrowing and various types of derivative instruments, including swaps, futures contracts, and options, although not all such derivatives will be used at all times. Such derivatives may trade over-the-counter or on an exchange and may principally be used for one or more of the following purposes: speculation, currency hedging, duration management, credit deterioration hedging, hedges against broad market movements, or to pursue the Fund’s investment objective. The Fund may borrow to the maximum extent permitted by applicable law. The Fund may also invest in repurchase agreements and borrow through reverse repurchase agreements.

Investment decisions are made based on fundamental research and analysis to identify issuers with the ability to improve their credit profile over time with attractive valuations, resulting in both income and potential capital appreciation. In selecting investments, including Structured Products, the Adviser may consider maturity, yield and ratings information and opportunities for price appreciation among other criteria. The Adviser also analyzes a variety of factors when selecting investments for the Fund, such as collateral quality, credit support, structure and market conditions. The Adviser attempts to diversify risks that arise from position sizes, geography, ratings, duration, deal structure and collateral values. The Adviser seeks to limit risk of principal by targeting assets that it considers undervalued. As part of its investment process, the Adviser also considers certain environmental, social and governance (“ESG”) and sustainability factors that it believes could have a material impact on certain securities in which the Fund

may invest. These determinations may not be conclusive, and securities that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities that may be positively impacted by such factors.
