This Fund may not be suitable for all investors. • The Fund’s market value will change in response to interest rate changes and market conditions among other factors. In general, bond prices rise when interest rates fall and vice versa. • The Fund’s exposure to high yield securities may subject the Fund to greater volatility. • When market conditions are deemed appropriate, the Fund will leverage to the full extent permitted by its investment policies and restrictions and applicable law. Leveraging will exaggerate the effect on net asset value of any increase or decrease in the market value of the Fund’s portfolio. • The Fund may invest in derivative instruments, which may be more volatile and less liquid, increasing the risk of loss when compared to traditional securities. Certain of the derivative instruments are also subject to the risks of counterparty default and adverse tax treatment. • Instruments and strategies (such as borrowing transactions and reverse repurchase agreements) may provide leveraged exposure to a particular investment, which will magnify any gains or losses on those investments. • Investments in reverse repurchase agreements expose the Fund to the many of the same risks as investments in derivatives. • The Fund’s investments in other investment vehicles subject the Fund to those risks and expenses affecting the investment vehicle. • The Fund’s investments in foreign securities carry additional risks when compared to U.S. securities, due to the impact of diplomatic, political or economic developments in the country in question (investments in emerging markets securities are generally subject to an even greater level of risks). • Investments in syndicated bank loans generally offer a floating interest rate and involve special types of risks. • The Fund’s investments in municipal securities can be affected by events that affect the municipal bond market. • The Fund’s investments in real estate securities subject the Fund to the same risks as direct investments in real estate, which is particularly sensitive to economic downturns. • The Fund’s investments in restricted securities may involve financial and liquidity risk. • You may have a gain or loss when you sell your shares. • It is important to note that the Fund is not guaranteed by the U.S. government. • Please read the prospectus for more detailed information regarding these and other risks.
