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. • Investments in high-yield ("junk") bonds involve greater risk of price volatility, illiquidity, and default than higher-rated debt securities. • The risks associated with mortgage-related and asset-backed securities as well as collateralized loan obligations (CLOs) include credit, interest-rate, prepayment, liquidity, default and extension risk. There are additional risks associated with credit risk transfer securities. • 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. • Loans can be difficult to value and less liquid than other types of debt instruments; they are also subject to nonpayment, collateral, bankruptcy, default, extension, prepayment and insolvency risks. • Fixed income security risks include credit, liquidity, call, duration, event and interest-rate risk. As interest rates rise, bond prices generally fall. • 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. • Foreign investments 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. • Restricted securities may be more difficult to sell and price than other securities. • The Fund's investments may fluctuate in value over a short period of time. • 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.
