Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. For example, the price of a bond with an effective duration of two years will rise (fall) two percent for every one percent decrease (increase) in its yield, and the price of a five-year duration bond will rise (fall) five percent for a one percent decrease (increase) in its yield. Greater sensitivity to changes in interest rates typically corresponds to higher volatility and higher risk.

Yield curve risk is the risk associated with either a flattening or steepening of the yield curve, which is a result of changing yields among comparable bonds with different maturities. When market interest rates, or yields, increase, the price of a bond will decrease and vice versa. When the yield curve shifts, the price of the bond, which was initially priced based on the initial yield curve, will change in price. If the yield curve flattens, then the yield spread between long- and short-term interest rates narrows, and the price of the bond will change accordingly. If the bond is short-term and the yield decreases, the price of this bond will increase. If the yield curve steepens, this means that the spread between long- and short-term interest rates increases. Therefore, long-term bond prices, like the ones held by the Fund, will decrease relative to short-term bonds. Changes in the yield curve are based on bond risk premiums and expectations of future interest rates.

Because the values of lower-rated and comparable unrated debt securities are affected both by credit risk and interest rate risk, the price movements of such lower grade securities typically have not been highly correlated to the fluctuations of the prices of investment grade quality securities in response to changes in market interest rates. The Fund’s investments in inverse floating rate securities, as described herein under “Inverse Floating Rate Securities Risk” and “Leverage Risk,” will tend to increase common share interest rate risk.

Duration Risk. Duration is the sensitivity, expressed in years, of the price of a fixed-income security to changes in the general level of interest rates (or yields). Securities with longer durations tend to be more sensitive to interest rate (or yield) changes, which typically corresponds to increased volatility and risk, than securities with shorter durations. For example, if a security or portfolio has a duration of three years and interest rates increase by 1
