There is no assurance that a closed end fund will achieve its investment objective. Like any stock, a closed end fund's share price will fluctuate with market conditions and other factors. At the time of sale, your shares may have a market price that is above or below net asset value, and may be worth more or less than your original investment. Accordingly, it is possible to lose money investing in the Trust. These funds are subject to credit and interest-rate risk. Credit risk refers to the ability of an issuer to make timely payments of interest and principal. Investments in securities rated below investment grade present greater risk of loss to principal and interest than investment in higher-quality securities. Interest-rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. In a declining interest-rate environment, the portfolio may generate less income. In a rising interest-rate environment, bond prices fall. Should the funds employ leverage, the portfolios may experience increased volatility. Income from the Trusts may subject certain individuals to the federal Alternative Minimum Tax (AMT).
