The Fund benefited from a slightly longer-than-normal duration during the period. Our decision to extend duration stems from the Build America Bonds, or BAB program, which has helped to support municipal bond prices by reducing the supply of longer-dated, tax-free municipal bonds. The BAB program is scheduled to run through the end of 2010, but Congressional legislation may extend the program beyond that date. We continue to favor longer-dated high-coupon bonds with shorter call features. These holdings can benefit from the steep yield curve by generating attractive income flow. At the same time, their shorter call dates help to limit the risk of an adverse change in interest rates.
The Fund's high level of credit quality detracted from quarterly return as lower-rated investment-grade bonds outperformed higher-rated issues. During the period, we maintained a high-quality profile and focused on bonds with a greater margin of safety, such as unlimited-tax general obligation bonds and essential-service dedicated revenue bonds.

If you are an investor who favors current income exempt from regular federal income tax, this Fund may be ideal for you. It is particularly well suited for income-oriented investors in higher tax brackets willing to assume some risk. Income from the Fund may be subject to federal alternative minimum tax (AMT), state and local taxes.

- Maintain a dollar-weighted average maturity range, under normal circumstances, between 10 and 30 years. This segment of the municipal market, while potentially more volatile, also may provide higher yields than shorter-term securities.
- Invest in high-quality securities, primarily investment-grade debt.
- Select investments on the basis of their relative value with a focus on total return.
