Statement of Additional Information

Shareholder Report

Past performance is no guarantee or indication of future results. The rate of return will vary and the principal value of an investment will fluctuate. Shares, if redeemed, may be worth more or less than their original cost. Performance does not reflect the effect of sales charges, fees, or taxes. If such charges were included, performance would be lower. Return figures reflect any change in price per share, and assume the reinvestment of dividends and capital gain distributions, if any.

IMPORTANT PERFORMANCE INFORMATION

Performance data quoted herein represents past performance. Past performance does not guarantee or indicate future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be higher or lower than the performance data quoted. Total returns of the Fund as of the most recent month-end will be made available at Current Fund Returns by the seventh business day following that month-end.

Return figures reflect any change in price per share, and assume the reinvestment of dividends and capital gain distributions, if any. Average annual total return figures for Class A shares are calculated without and with the effect of the initial maximum sales charge. The average annual total returns (with sales charges) for all periods presented for Class A shares reflect the maximum initial sales charge of 4.50% that went into effect January 7, 2008. Although the Fund's Class A share returns reflect the 4.50% maximum initial sales charge, the actual returns for periods prior to January 7, 2008, would have been lower if a 4.75% maximum initial sales charge then in effect was incurred. Effective June 4, 2007, there is no initial sales charge on purchases of Class C shares. The chart and tables do not reflect the performance of Class C shares, which would differ due to different sales charges, fees and expenses. Return information on Class C shares are available here.

A WORD ABOUT RISK

Income is generally subject to state and local taxes. Capital gain distributions are subject to federal, state, and local taxes. Income may be subject to the alternative minimum tax.

Fixed-income securities owned by the Fund are subject to interest-rate risk, credit risk, prepayment risk, and market risk.

To the extent that the Fund concentrates its investments in municipal securities issued by a single state and its municipalities, specific events or factors affecting a particular state may have an impact on the municipal securities of that state without affecting the municipal market in general.

There is no guarantee that the Fund’s investment goals/objectives will be met, and you could lose money.

On July 7, 2008, Ameriprise Financial, Inc. (“Ameriprise”) announced an agreement to acquire J. & W. Seligman & Co. Incorporated (“Seligman”), the Fund’s manager, in a transaction that is likely to close in the fourth quarter of 2008. Consummation of Ameriprise’s acquisition of Seligman will result in a change of control of Seligman and an assignment and automatic termination of the Fund’s management agreement with Seligman. At a meeting on July 29, 2008, the Fund's Board approved new advisory and administration agreements between the Fund and subsidiaries of Ameriprise. The new advisory agreement will be presented to the shareholders of the Fund for their approval.

FOOTNOTES
1 Quality composition is shown as a percentage of net assets.
2 Top 5 holdings exclude short-term instruments and are shown as a percentage of total net assets. The Fund is actively managed and holdings are subject to change. There can be no assurance that the securities listed above have remained or will remain in the Fund’s portfolio.

3 Bond duration is the average amount of time that it takes to receive the interest and principal of a bond or portfolio of bonds. The duration formula is based on a formula that calculates the weighted average of the cash flows (interest and principal payments) of the bond, discounted to the present time. Option Adjusted Duration is the modified duration of a bond after adjusting for any embedded optionality. The Option Adjusted measure of duration takes into account the fact that yield changes may change the expected cash flows of the bond because of the presence of an embedded option, such as a call or put.
4 Weighted average maturity is the number of years to stated maturity, weighted based upon current market value.
5 Holdings are shown as a percentage of net assets.
