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. • 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, such as China and the Asian region. • Risks associated with investments in China include currency fluctuation, political, economic, social, environmental, regulatory and other risks, including risks associated with differing legal standards. Trading in Chinese government bonds and other Chinese-based debt instruments through Bond Connect, which is a relatively new program, is subject to certain restrictions and additional risks. • Fixed income security risks include credit, liquidity, duration, event, inflation and interest-rate risk. As interest rates rise, bond prices generally fall. • Investments in high-yield ("junk") bonds are considered speculative, involve heightened credit risk and greater risk of price volatility, illiquidity, and default than investment grade bonds. • 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, valuation, and counterparty risk. • The Fund's investments may fluctuate in value over a short period of time. • 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. • The value of inflation-protected securities (IPS) generally fluctuates with changes in real interest rates, and the market for IPS may be less developed or liquid, and more volatile, than other securities markets. • Restricted securities may be more difficult to sell and price than other securities. • The Fund may have high portfolio turnover, which could increase its transaction costs and an investor's tax liability.
