High yield investments include domestic and foreign bonds (including corporate bonds), convertible debt securities, mezzanine investments, collateralized debt obligations, bank loans, loan assignments and loan participations and mortgage-backed and asset-backed securities. Such high yield investments acquired by the High Yield Fund will generally be in the lower rating categories of the major rating agencies (BB or lower by S&P Global Ratings or Fitch Ratings, Inc. or Ba or lower by Moodys Investor Services) or will be determined by the High Yield Fund management team to be of similar quality. The High Yield Fund may also invest in other investment companies, including affiliated investment companies such as affiliated exchange-traded funds, to gain exposure to such high yield investments. Split rated bonds and other fixed-income securities (securities that receive different ratings from two or more rating agencies) are valued as follows: if three agencies rate a security, the security will be considered to have the median credit rating; if two of the three agencies rate a security, the security will be considered to have the lower credit rating. The High Yield Fund may invest up to 30% of its assets in non-dollar denominated bonds of issuers located outside of the United States. The High Yield Funds investment in non-dollar denominated bonds may be on a currency hedged or unhedged basis. The High Yield Fund may also invest in convertible and preferred securities. The High Yield Fund can also invest, to the extent consistent with its investment objective, in non-U.S. and emerging market securities and currencies. The High Yield Fund may invest in securities of any rating, and may invest up to 10% of its assets (measured at the time of investment) in distressed securities that are in default or the issuers of which are in bankruptcy. The High Yield Fund may buy or sell options or futures on a security or an index of securities, or enter into swap agreements, including total return, interest rate and credit default swaps, or foreign currency transactions (collectively, commonly known as derivatives). The High Yield Fund may use derivative instruments to hedge its investments or to seek to enhance returns. The High Yield Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The High Yield Fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. Show less
