This policy may be changed without shareholder approval; however, you would be notified upon 60 days notice in writing of any changes. ?These mortgage-related securities may include mortgage-backed securities such as mortgage pass-through securities, collateralized mortgage obligations (CMOs), stripped mortgage-backed securities (SMBS), commercial mortgage-backed securities (CMBS) and inverse floating rate obligations (inverse floaters). The mortgage-backed securities in which the Fund invests may be issued or guaranteed by the U.S. Government, its agencies or instrumentalities or may be offered by non-governmental issuers, such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers. The Fund is not limited as to the maturities (when a debt security provides its final payment) or types of mortgage-backed securities in which it may invest. In making investment decisions, the Adviser considers economic developments, interest rate levels and other factors. To identify attractive sectors and securities, the Adviser employs both top-down and bottom-up analyses. In addition, the Adviser combines quantitative and fundamental methodologies to limit the Funds investment universe from which potential investments are then selected. In a securitized strategy, such as the strategy employed by the Fund, a majority of the Advisers investment process is security selection related. When deemed by the Adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the Adviser considers environmental, social and/or governance issues (referred to as ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Funds portfolio. The Fund may invest up to 50% of its net assets in high yield securities (commonly referred to as junk bonds). High yield securities are fixed-income securities rated by one or more rating agencies below Baa3 by Moodys Investors Service, Inc. (Moodys), below BBB- by S&P Global Ratings Group, a division of S&P Global Inc. (S&P), below BBB- by Fitch Ratings, Inc. (Fitch), or the equivalent by another nationally recognized statistical rating organization (NRSRO), or if unrated, considered by the Adviser to be of equivalent quality. One type of mortgage-backed security in which the Fund may invest is a mortgage pass-through security, which represents a participation interest in a pool of residential mortgage loans originated by U.S. governmental or private lenders such as banks. Mortgage pass-through securities provide for monthly payments that are a pass-through of the monthly interest and principal payments made by the individual borrowers on the pooled mortgage loans. CMOs are debt obligations collateralized by mortgage loans or mortgage pass-through securities (collectively Mortgage Assets). CMOs are issued in multiple classes and each class has a fixed or floating rate and a stated maturity or final distribution date. Certain classes will have more predictable cash flows than others. The Fund may invest in any class of CMO. SMBS are derivative multi-class mortgage-backed securities. A common type of stripped mortgage-backed security will have one class receiving some of the interest and most of the principal from the Mortgage Assets, while the other class receives most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest (the interest-only or IO class), while the other class will receive all of the principal (the principal-only or PO class). CMBS are generally multi-class or pass-through securities backed by a mortgage loan or a pool of mortgage loans secured by commercial property, such as industrial and warehouse properties, office buildings, retail space and shopping malls, multifamily properties and cooperative apartments. Inverse floaters are obligations which pay interest at rates that vary inversely with changes in market rates of interest. Because the interest rate paid to holders of such obligations is generally determined by subtracting a variable or floating rate from a predetermined amount, the interest rate paid to holders of such obligations will decrease as such variable or floating rate increases and increase as such variable or floating rate decreases. In addition, the Fund may invest in to-be-announced pass-through mortgage securities, which settle on a delayed delivery basis (TBAs). The Fund also may invest in other U.S. government securities, including, but not limited to, U.S. Treasury bills, notes and bonds, securities (including mortgage-backed securities) issued by agencies or instrumentalities of the U.S. Government which may or may not be backed by the full faith and credit of the United States, and securities issued by agencies or instrumentalities which are backed solely by the credit of the ?issuing agency or instrumentality. The Fund may also invest in asset-backed securities and restricted and illiquid securities. In addition, the Fund may invest up to 20% of its net assets in foreign securities, including U.S. dollar-denominated securities issued in the U.S. capital markets by foreign issuers, some of which are commonly known as Yankee Bonds and non-U.S. dollar- denominated securities, including Eurobonds. The Fund may, but it is not required to, use derivatives and similar instruments for a variety of purposes, including hedging, risk management, portfolio management or to earn income. The Funds use of derivatives may involve the purchase and sale of derivative instruments such as futures, options, swaps and other similar instruments and techniques. The Fund may use foreign currency forward exchange contracts, which are also derivatives, in connection with its investments in foreign securities. These derivative instruments will be counted toward the Funds 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.
