Securities may be rated either investment grade or below investment grade and denominated in any currency, hedged or un-hedged. The amount of the Funds assets committed to any one asset class or market segment will fluctuate. Under normal circumstances, the Fund may invest up to 65% of its net assets in any one asset class or market segment. The Adviser has the flexibility to select any combination of at least two asset classes of the aforementioned groups depending upon market conditions and the current economic environment and, as a result, at any given time the Funds assets may be invested in certain groups and not others. The Funds investment process incorporates information about environmental, social and governance issues (also referred to as ESG) via an integrated approach within the investment teams fundamental investment analysis framework. The Adviser may engage with management of certain issuers regarding corporate governance practices as well as what the Adviser deems to be materially important environmental and/or social issues facing a company. The corporate securities in which the Fund will invest may include fixed-income securities issued by corporations located in ?or outside of the United States, certificates of deposit and bankers ?acceptances issued or guaranteed by, or time deposits maintained ?at, banks, commercial paper and convertible securities. The types of mortgage-backed securities in which the Fund ?may invest include mortgage pass-through securities, ?collateralized mortgage obligations (CMOs), stripped ?mortgage-backed securities (SMBS) and commercial ?mortgage-backed securities (CMBS). 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 (when a debt security provides its final payment) 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 SMBS 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. In addition, the Fund may invest in to-be-announced pass-through mortgage-backed securities, which settle on a delayed delivery basis (TBAs). Asset-backed securities represent an interest in a pool of assets ?such as, but not limited to, automobile loans, credit card receivables, student loans or home equity (prime and subprime) loans that have been securitized in pass-through structures similar to mortgage-backed securities. The Fund may invest in fixed-income securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities or in fixed-income securities issued or guaranteed by foreign governments or supranational organizations or any of their instrumentalities, including debt obligations of governmental issuers located in emerging market or developing countries and sovereign debt. The Fund may also invest generally in foreign securities that are denominated in U.S. dollars or in currencies other than U.S. dollars. In pursuit of its investment objectives, the Fund may regularly enter into currency derivatives, including, but not limited to, foreign currency forward exchange contracts, and currency and currency index futures and options contracts for hedging and non-hedging purposes. The use of these currency derivatives may allow the Fund to obtain net long or net negative (short) exposure to selected currencies. At times, the Fund may enter into cross-currency transactions involving currencies other than those in which securities held or proposed to be purchased are denominated. In addition to its use of currency derivatives, 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 seek 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 invest in loan-related investments, such as public bank loans made by banks or other financial institutions and loan ?participations and assignments, which may be rated investment grade or below investment grade. The Fund may also invest in restricted and illiquid securities. The Fund will maintain an average credit rating of at least investment grade (BBB- by S&P Global Ratings, a division of S&P Global Inc. (S&P) or Fitch Ratings, Inc. (Fitch), or Baa3 by Moodys Investors Service, Inc. (Moodys)). Although the Funds average credit rating will be investment grade or higher, the Fund may invest in securities that are rated below investment grade (rated below BBB by either S&P or Fitch, or below Baa by Moodys) or in unrated securities considered to be of comparable quality by the Adviser (often referred to as junk instruments). If securities are rated differently by two or more rating agencies, the highest rating will be used. Show less
