Investor Guide Fact Sheet Prospectus 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.

Seligman has contractually agreed to waive its management fee and/or to reimburse the Fund’s “other expenses” (i.e., those expenses other than management fees, 12b-1 fees, interest on borrowings, and extraordinary expenses, including litigation expenses) to the extent such expenses exceed 0.45% per annum of the Fund’s average daily net assets. This undertaking will remain in effect at least until April 30, 2009. Other fee waiver/expense reimbursement arrangements were in effect since the Fund’s inception. Absent such waivers/reimbursements, returns would have been lower.

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 5.75% that went into effect January 7, 2008. 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 B, C, or R shares, which would differ due to different sales charges, fees and expenses. Return information on Class B, C, and R shares are available here.

A WORD ABOUT RISK

Real estate investments may be subject to specific risks, such as risks to general and local economic conditions, and risks related to individual properties. Investing in one economic sector, such as real estate, may result in greater price fluctuations than owning a portfolio of diversified investments.

Smaller-company stocks may experience larger price fluctuations than large-company stocks or other types of investments. The Fund is a “non-diversified” mutual fund and thus may hold fewer securities than other funds. A decline in the value of those investments would cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Dividends paid by the Fund will be taxable as ordinary income. It is not expected that income dividends paid by the Fund will be eligible for the reduction in dividend tax rates set forth in the Jobs and Growth Tax Relief Reconciliation Act of 2003.

Distributions by the Fund may include a return of capital. A return of capital is not net profits of the Fund but instead a return of a portion of your original investment.

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 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, as well as the sub-advisory agreement relating to the Fund. At a meeting on July 29, 2008, the Fund's Board approved new advisory and administration agreements between the Fund and subsidiaries of Ameriprise, and a new sub-advisory agreement for the Fund. If approved by the Fund’s Board, the new advisory and sub-advisory agreements will be presented to the shareholders of the Fund for their approval.
