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. • Investments in high-yield ("junk") bonds involve greater risk of price volatility, illiquidity, and default than higher-rated debt securities. • Fixed income security risks include credit, liquidity, call, duration, event and interest-rate risk. As interest rates rise, bond prices generally fall. • 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. • 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. • 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.
