° The distributor of the Fund has contractually agreed through December 31, 2013 to reduce its distribution and service (12b-1) fees for Class A shares to .25% of the average daily net assets of Class A shares. This waiver may not be terminated by the distributor prior to December 31, 2013. The decision on whether to renew, modify or discontinue the waiver is subject to review by the distributor and the Fund's Board of Trustees.
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 47% of the average value of its portfolio.
The bar chart and Average Annual Total Returns table demonstrate the risk of investing in the Fund by showing how returns can change from year to year and by showing how the Fund's average annual total returns for the share class compare with a broad-based securities market index and a group of similar mutual funds.

The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year, that the Fund's operating expenses remain the same and that all dividends and distributions are reinvested. Your actual costs may be higher or lower.

<b>If Shares Are Not Redeemed</b>
<b>Portfolio Turnover.</b>
The Fund invests, under normal circumstances, at least 80% of the Fund's investable assets in obligations the income from which is exempt from federal income tax, that is, municipal obligations. This is a fundamental policy of the Fund, which means that it may not be changed without shareholder approval. The term “investable assets” in this prospectus refers to the Fund's net assets plus any borrowings for investment purposes. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions.<br/><br/>The Fund's investments permitted by this policy may include certain municipal bonds, the interest on which is subject to the federal alternative minimum tax (AMT). The Fund's portfolio consists primarily of investment grade long-term municipal bonds, which are bonds rated Baa3 or higher by Moody's Investors Service (Moody's), and BBB- or higher by Standard & Poor's Ratings Group (S&P), or comparably rated by another major rating service, and unrated debt obligations that the investment subadviser believes are comparable in quality. The Fund may invest up to 15% of the Fund's investable assets in “below-investment grade” or high-yield municipal debt obligations, commonly known as junk bonds. Below-investment grade securities are rated below Baa3 by Moody's and below BBB- by S&P, or comparably rated by another major rating service, and are considered speculative. The Fund may invest in obligations the interest and/or principal payments on which are insured by the bond insurers or other parties. <br/><br/>In seeking to achieve the Fund's investment objective, the investment subadviser will purchase securities that it believes represent the best values based on yield, maturity, issue, quality characteristics and expectations regarding economic and political developments, including movements in interest rates and demand for municipal bonds. While we make every effort to achieve our objective, we can't guarantee success.
All investments have risks to some degree. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.<br/><br/><b>Recent Market Events.</b> The equity and debt capital markets in the United States and internationally have experienced unprecedented volatility. The financial crisis has caused a significant decline in the value and liquidity of many securities. This environment could make identifying investment risks and opportunities especially difficult for the investment subadviser. These market conditions may continue or get worse. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be known for some time. <br/><br/><b>Risk of Increase in Expenses. </b> Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. <br/><br/><b>Municipal Bonds Risk. </b> Municipal bonds are subject to credit risk, market risk and interest rate risk. The Fund's holdings, share price, yield and total return may also fluctuate in response to municipal bond market movements. Municipal bonds are also subject to the risk that potential future legislative changes could affect the market for and value of municipal bonds, which may adversely affect the Fund's yield or the value of the Fund's investments in municipal bonds. Certain municipal bonds with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project's ability to make payments of principal and interest on these securities. Municipal securities of a particular state are vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism and catastrophic natural disasters, such as hurricanes or earthquakes. Many municipal bonds are also subject to prepayment risk—when interest rates fall, the issuers may redeem a security by repaying it early, which may reduce the Fund's income if the proceeds are reinvested at a lower interest rate. <br/><br/><b>Insured Municipal Bonds Risk. </b> The Fund may purchase municipal bonds that are insured to attempt to reduce credit risks. Although insurance coverage reduces credit risks by providing that the insurer will make timely payment of interest and/or principal, it does not provide protection against market fluctuations of insured bonds or fluctuations in the price of the shares of the Fund. An insured municipal bond fluctuates in value largely based on factors relating to the insurer's creditworthiness or ability to satisfy its obligations. The Fund cannot be certain that any insurance company will make the payments it guarantees. <br/><br/><b>Junk Bonds Risk. </b> High-yield, high-risk bonds have predominantly speculative characteristics, including particularly high credit risk. Junk bonds tend to be less liquid than higher-rated securities. The liquidity of particular issuers or industries within a particular investment category may shrink or disappear suddenly and without warning. The non-investment grade bond market can experience sudden and sharp price swings and become illiquid due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high profile default or a change in the market's psychology. <br/><br/><b>Interest Rate Risk. </b> This is the risk that the securities in which the Fund invests could lose value because of interest rate changes. For example, bonds tend to decrease in value if interest rates rise. Debt obligations with longer maturities generally are more sensitive to interest rate changes. In addition, short-term and long-term interest rates do not necessarily move in the same direction or by the same amount. An instrument's reaction to interest rate changes depends on the timing of its interest and principal payments and the current interest rate for each of those time periods. Instruments with floating interest rates can be less sensitive to interest rate changes. Certain types of debt obligations are also subject to prepayment and extension risk. When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as “prepayment risk.” When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Fund's holdings may fall sharply. This is referred to as “extension risk.” <br/><br/><b>Credit Risk. </b> This is the risk that the issuer, the guarantor or the insurer of a fixed-income security, or the counterparty to a contract, may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Additionally, the securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer or counterparty to pay back debt. The longer the maturity and the lower the credit quality of a bond, the more sensitive it is to credit risk. <br/><br/><b>Market Risk. </b> Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Securities markets are volatile. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Regardless of how well an individual investment performs, if financial markets go down, you could lose money. <br/><br/><b>Management Risk. </b> Actively managed mutual funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these techniques will produce the desired results. Additionally, the securities selected by the subadviser may underperform the markets in general, the Fund's benchmark and other mutual funds with similar investment objectives. <br/><br/>For more information on the risks of investing in this Fund, please see <font style="FONT-STYLE: italic">How the Fund Invests—Investment Risks</font> in the Prospectus and <font style="FONT-STYLE: italic">Investment Risks and Considerations </font>in the SAI.
