Important Risks: Investing involves risk, including the possible loss of principal. Security prices fluctuate in value depending on general market and economic conditions and the prospects of individual companies. The Fund may allocate a portion of its assets to specialist portfolio managers, which may not work as intended. • Fixed income security risks include credit, liquidity, call, duration, and interest-rate risk. As interest rates rise, bond prices generally fall. • Foreign investments, including foreign government debt, may be more volatile and less liquid than U.S. investments and are subject to the risk of currency fluctuations and adverse political, economic and regulatory developments. These risks may be greater, and include additional risks, for investments in emerging markets or if the Fund focuses in a particular geographic region or country. • Investments in high-yield ("junk") bonds involve greater risk of price volatility, illiquidity, and default than higher-rated debt securities. • Mortgage-related and asset-backed securities' risks include credit, interest-rate, prepayment, and extension risk. • Derivatives are generally more volatile and sensitive to changes in market or economic conditions than other securities; their risks include currency, leverage, liquidity, index, pricing, regulatory and counterparty risk. • Because the Fund is non-diversified, it may invest in a smaller number of issuers, and may be more exposed to risks and volatility than a more broadly diversified fund. • Restricted securities may be more difficult to sell and price than other securities. • Obligations of U.S. Government agencies are supported by varying degrees of credit but are generally not backed by the full faith and credit of the U.S. Government. • The Fund may have high portfolio turnover, which could increase its transaction costs and an investor's tax liability. • The purchase of securities in the To-Be-Announced (TBA) market can result in higher portfolio turnover and related expenses as well as price and counterparty risk. • Financially material environmental, social and/or governance (ESG) characteristics are one of several factors that may be considered and as a result, the investment process may not work as intended.
