Experience Seligman has been in business for more than 140 years, at times playing a central role in the financial development of the country and its markets. Over that time, the firm has managed clients’ wealth through dramatic market changes and has remained a consistent, reliable presence on Wall Street. Today, Seligman is drawing on its long history and long-term perspective as we focus on the future and on developing investment solutions that help clients arrive at their goals. Insight Asset management is driven by insight — into the direction of the economy, how companies will perform, how markets will behave, and how investors will respond. Portfolio managers at the firm have been in the investment business, on average, for more than 20 years. Over that time, they have refined their ability to assess a company’s prospects, management, and products, while also weighing the impact of economic and market cycles, new trends, and developing technologies. Solutions Seligman’s commitment to the development of innovative investment products — including the nation’s first growth mutual fund, pioneering single-state municipal funds, and one of the country’s premier technology funds — defines our past and informs our future. Our ongoing research into the nature of investment risk — begun in the early 1990s — has resulted in the Seligman Time Horizon Matrix^®asset allocation strategy that redefines the relationship between risk and reward over time. The strategy offers investors a variety of investment solutions for goals ranging from college savings to retirement planning. Whether you select Seligman for one investment product, or as a comprehensive asset manager, we believe we can help you reach your goals.	Table of Contents

	To The Shareholders


	We are pleased to present your mid-year shareholder report for Seligman Communications and Information Fund, Inc. This report contains the Fund’s investment results, portfolio of investments, and financial statements as of June 30, 2008. For the six months ended June 30, 2008, Seligman Communications and Information Fund posted a total return, based on the net asset value of Class A shares (excluding sales charges), of –7.8%. During the same period, the Fund’s peers, as measured by the Lipper Science & Technology Funds Average, returned –12.6%. The Fund’s benchmark, the S&P North American Technology Sector Index (formerly the S&P GSTI Composite Index), returned –12.2%. The broad equity market, as measured by the S&P 500 Index, returned –11.9% for the same time period. On May 16, 2008, Class D shares of the Fund were converted to Class C shares at their respective net asset values. The conversion did not affect individual shareholder account values. Effective at the close of business on May 16, 2008, Class D shares are no longer offered by the Fund. 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 Seligman becoming a wholly-owned subsidiary of RiverSource Investments, LLC (“RiverSource”), a subsidiary of Ameriprise, and a change of control of Seligman and an assignment and automatic termination of the Fund’s management agreement with Seligman. On July 29, 2008, the Fund’s Board approved a new advisory agreement with RiverSource, and a new administration agreement with Ameriprise. The new advisory agreement will be presented to the shareholders of the Fund for their approval. Please note that Paul Wick, the Fund’s Portfolio Manager, Ajay Diwan and Reema Shah, the Fund’s Co-Portfolio Managers, and the Seligman Technology Group will continue to manage the Fund under the new advisory agreement. Thank you for your continued support of Seligman Communications and Information Fund. By order of the Board of Directors,

Performance Overview

This section of the report is intended to help you understand the performance of Seligman Communications and Information Fund and to provide a summary of the Fund’s portfolio characteristics.

Performance data quoted in this report represents past performance and does not guarantee or indicate future investment results. The rates 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. Current performance may be lower or higher than the performance data quoted. Total returns of the Fund (except for Class I shares) as of the most recent month-end will be available at www.seligman.com¹by the seventh business day following that month-end. Calculations assume reinvestment of distributions. Performance data quoted does not reflect the deduction of taxes that an investor may pay on distributions or the redemption of shares.

Returns for Class A shares are calculated with and without the effect of the initial 5.75% maximum sales charge that became effective on January 7, 2008. Returns for Class B shares are calculated with and without the effect of the maximum 5% contingent deferred sales charge (“CDSC”), charged on redemptions made within one year of the date of purchase, declining to 1% in the sixth year and 0% thereafter. Returns for Class C and Class R shares are calculated with and without the effect of the 1% CDSC, charged on redemptions made within one year of purchase. Returns for Class C shares would have been lower for periods prior to June 4, 2007 if the 1% initial sales charge then in effect was incurred. On May 16, 2008, Class D shares of the Fund were converted to Class C shares at their respective net asset values. Effective at the close of business on May 16, 2008, Class D shares are no longer offered by the Fund. Class I shares do not have sales charges, and returns are calculated accordingly.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

**		The S&P North American Technology Sector Index, the Standard & Poor’s 500 Composite Stock Price Index (“S&P 500 Index”), and the Lipper Science & Technology Funds Average (“Lipper Average”) are unmanaged benchmarks that assume reinvestment of all distributions. The Lipper Average excludes the effect of fees, taxes, and sales charges. The S&P North American Technology Sector Index and the S&P 500 Index also exclude the effect of expenses. The S&P 500 Index measures the performance of 500 of the largest US companies based on market capitalizations. The Lipper Average measures the performance of mutual funds that invest at least 65% of their equity portfolios in science and technology stocks. The S&P North American Technology Sector Index is a modified capitalization-weighted index based on a universe of technology-related stocks. Investors cannot invest directly in an average or an index.
†		The CDSC is 5% if you sell your shares within one year of purchase and 2% for the five-year period.
‡		The ten-year return for Class B shares reflects automatic conversion to Class A shares approximately eight years after their date of purchase.

Understanding and Comparing
Your Fund’s Expenses

As a shareholder of the Fund, you incur ongoing expenses, such as management fees, distribution and/or service (12b-1) fees (if applicable), and other Fund expenses. The information below is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare them with the ongoing expenses of investing in other mutual funds. Please note that the expenses shown in the table are meant to highlight your ongoing expenses only and do not reflect any transactional costs, such as sales charges (also known as loads) on certain purchases or redemptions. Therefore, the table is useful in comparing ongoing expenses only, and will not help you to determine the relative total expenses of owning different funds. In addition, if transactional costs were included, your total expenses would have been higher.

The table is based on an investment of $1,000 invested at the beginning of January 1, 2008, and held for the entire six-month period ended June 30, 2008.

Actual Expenses
The table below provides information about actual expenses and actual account values. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value at the beginning of the period by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During Period” for the Fund’s share class that you own to estimate the expenses that you paid on your account during the period.

Hypothetical Example for Comparison Purposes
The table below also provides information about hypothetical expenses and hypothetical account values based on the actual expense ratios of each class and an assumed rate of return of 5% per year before expenses, which is not the actual return of any class of the Fund. The hypothetical expenses and account values may not be used to estimate the ending account value or the actual expenses you paid for the period. You may use this information to compare the ongoing expenses of investing in the Fund and other mutual funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other mutual funds.

			Actual		Hypothetical
	Beginning		Ending	Expenses Paid	Ending	Expenses Paid
	Account	Annualized	Account	During Period	Account	During Period
	Value	Expense	Value	1/1/08 to	Value	1/1/08 to
	1/1/08	Ratio*	6/30/08	6/30/08**	6/30/08	6/30/08**
Class A	$1,000.00	1.49%	$922.30	$ 7.10	$1,017.45	$ 7.45
Class B	1,000.00	2.24	918.90	10.66	1,013.72	11.18
Class C	1,000.00	2.24	919.20	10.66	1,013.72	11.18
Class I	1,000.00	1.03	924.50	4.91	1,019.74	5.16
Class R	1,000.00	1.74	921.30	8.29	1,016.21	8.70

*		Expenses of Class B, Class C, Class I and Class R shares differ from the expenses of Class A shares due to the differences in 12b-1 fees and other class-specific expenses paid by each share class. See the Fund’s prospectuses for a description of each share class and its fees, expenses and sales charges.
**		Expenses are equal to the annualized expense ratio based on actual expenses for the period January 1, 2008 to June 30, 2008, multiplied by the average account value over the period, multiplied by 182/366 (number of days in the period).

Notes to Financial Statements (unaudited)

1.	Organization and Multiple Classes of Shares — Seligman Communications and Information Fund, Inc. (the “Fund”) is registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end diversified management investment company. The Fund offers the following five classes of shares:

	Class A shares are subject to a continuing service fee of up to 0.25% on an annual basis and, through January 6, 2008, were sold with an initial sales charge of up to 4.75% (5.75% effective January 7, 2008). Class A shares purchased in an amount of $1,000,000 or more are sold without an initial sales charge but are subject to a contingent deferred sales charge (“CDSC”) of 1% on redemptions made within 18 months of purchase. Effective January 7, 2008, eligible employee benefit plans which have at least $2,000,000 in plan assets may purchase Class A shares at net asset value, but, in the event of plan termination, will be subject to a CDSC of 1% on shares purchased within 18 months prior to plan termination.

	Class B shares are sold without an initial sales charge but are subject to a distribution fee of 0.75% and a service fee of up to 0.25% on an annual basis, and a CDSC, if applicable, of 5% on redemptions in the first year of purchase, declining to 1% in the sixth year and 0% thereafter. Class B shares will automatically convert to Class A shares approximately eight years after their date of purchase. If Class B shares of the Fund are exchanged for Class B shares of another Seligman mutual fund, the holding period of the shares exchanged will be added to the holding period of the shares acquired, both for determining the applicable CDSC and the conversion of Class B shares to Class A shares.

	Class C shares are sold without an initial sales charge but are subject to a distribution fee of up to 0.75% and a service fee of up to 0.25% on an annual basis, and a CDSC, if applicable, of 1% imposed on redemptions made within one year of purchase.

	The Board of Directors of the Fund approved the automatic conversion of all of the Fund’s outstanding Class D shares to Class C shares at their relative net asset values. The conversion was implemented on May 16, 2008. Effective at the close of business on May 16, 2008, the Fund no longer offers Class D shares. The conversion did not affect individual shareholder account values.

	Class I shares are offered to certain institutional clients and other investors, as described in the Fund’s Class I shares prospectus. Class I shares are sold without any sales charges and are not subject to distribution or service fees.

	Class R shares are offered to certain employee benefit plans and are not available to all investors. They are sold without an initial sales charge, but are subject to a distribution fee of up to 0.25% and a service fee of up to 0.25% on an annual basis, and a CDSC, if applicable, of 1% on certain redemptions made within one year of a plan’s initial purchase of Class R shares.

	All classes of shares represent interests in the same portfolio of investments, have the same rights and are generally identical in all respects except that each class bears its own class-specific expenses, and has exclusive voting rights with respect to any matter on which a separate vote of any class is required.

2.	Significant Accounting Policies — The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements. Actual results may differ from these estimates. These unaudited interim financial statements reflect all adjustments which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal recurring nature. The following summarizes the significant accounting policies of the Fund:

	a.	Security Valuation and Risk — Securities traded on an exchange are valued at the last sales price on the primary exchange or market on which they are traded. Securities not listed on an exchange or security market, or securities for which there is no last sales price, are valued at the mean of the most recent bid and asked prices or are valued by J. & W. Seligman & Co. Incorporated (the “Manager”) based on quotations provided by primary market makers in such securities. Securities for which market quotations are not readily available (or are otherwise no longer valid or reliable) are

Notes to Financial Statements (unaudited)

		valued at fair value determined in accordance with procedures approved by the Board of Directors. This can occur in the event of, among other things, natural disasters, acts of terrorism, market disruptions, intra-day trading halts, and extreme market volatility. The determination of fair value involves subjective judgments. As a result, using fair value to price a security may result in a price materially different from the prices used by other mutual funds to determine net asset value or the price that may be realized upon the actual sale of the security. Investments in foreign securities (including ADRs) are subject to certain risks, such as currency fluctuations, foreign taxation, differences in financial reporting practices, and rapid changes in political and economic conditions. Short-term holdings maturing in 60 days or less are valued at current market quotations or amortized cost if the Fund’s Manager believes it approximates fair value. Short-term holdings that mature in more than 60 days are valued at current market quotations until the 60th day prior to maturity and are then valued as described above for securities maturing in 60 days or less. On January 1, 2008, the Fund adopted Statement of Financial Accounting Standards No. 157 (“SFAS 157”), “Fair Value Measurements.” SFAS 157 establishes a three-tier hierarchy to classify the assumptions, referred to as inputs, used in valuation techniques (as described above) to measure fair value of the Fund’s investments. These inputs are summarized in three broad levels: Level 1 — quoted prices in active markets for identical investments; Level 2 — other significant observable inputs (including quoted prices in inactive markets or for similar investments); and Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining fair value) (Note 3). The inputs or methodology used for valuing securities may not be an indication of the risk associated with investing in those securities. The products of technology companies may be subject to severe competition and rapid obsolescence, and technology stocks may be subject to greater price fluctuations, government regulation, and limited liquidity as compared to other investments. In addition, investing in one economic sector, such as technology, may result in greater price fluctuations than owning a portfolio of diversified investments. The stocks of smaller companies may be subject to above-average market price fluctuations.

	b.	Foreign Currency Transactions — The books and records of the Fund are maintained in US dollars. The market value of investment securities, other assets and liabilities denominated in foreign currencies are translated into US dollars at the daily rate of exchange as reported by a pricing service. Purchases and sales of investment securities, income, and expenses are translated into US dollars at the rate of exchange prevailing on the respective dates of such transactions.

		The Fund does not isolate that portion of the results of operations resulting from changes in the foreign exchange rates from the fluctuations arising from changes in the market prices of securities held in the portfolio. Such fluctuations are included with the net realized and unrealized gain or loss from investments.

	c.	Options — The Fund is authorized to write and purchase put and call options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked to market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). The Fund, as writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. Written and purchased options are non-income producing investments.

	d.	Repurchase Agreements — The Fund may enter into repurchase agreements. Generally, securities received as collateral subject to repurchase agreements are deposited with the Fund’s custodian and, pursuant to the terms of the repurchase agreements, must have an aggregate market value greater than

Notes to Financial Statements (unaudited)

		or equal to the repurchase price plus accrued interest at all times. On a daily basis, the market value of securities held as collateral for repurchase agreements is monitored to ensure the existence of the proper level of collateral.

	e.	Restricted Cash — Restricted cash represents deposits that are being held by banks as collateral for letters of credit issued in connection with the Fund’s insurance policies.

	f.	Forward Currency Contracts — The Fund may enter into forward currency contracts in order to hedge its exposure to changes in foreign currency exchange rates on its foreign portfolio holdings, or other amounts receivable or payable in foreign currency. A forward contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. Certain risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts. The contracts are valued daily at current or forward exchange rates and any unrealized gain or loss is included in net unrealized appreciation or depreciation on translation of assets and liabilities denominated in foreign currencies and forward currency contracts. The gain or loss, if any, arising from the difference between the settlement value of the forward contract and the closing of such contract is included in net realized gain or loss from foreign currency transactions.

	g.	Multiple Class Allocations — All income, expenses (other than class-specific expenses), and realized and unrealized gains or losses are allocated daily to each class of shares based upon the relative value of shares of each class. Class-specific expenses, which include distribution and service (12b-1) fees and any other items that are specifically attributable to a particular class, are charged directly to such class. For the six months ended June 30, 2008, distribution and service (12b-1) fees, shareholder account services and registration expenses were class-specific expenses.

	h.	Security Transactions and Related Investment Income — Investment transactions are recorded on trade dates. Identified cost of investments sold is used for both financial reporting and federal income tax purposes. Dividends receivable are recorded on ex-dividend dates. Interest income is recorded on an accrual basis.

	i.	Distributions to Shareholders — Dividends and distributions to shareholders are recorded on ex-dividend date.

	j.	Taxes — There is no provision for federal income tax. The Fund has elected to be taxed as a regulated investment company and intends to distribute substantially all taxable net income and net gain realized. Withholding taxes on foreign dividends and interest and taxes on the sale of foreign securities have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules and rates.

		Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109,” requires the Fund to measure and recognize in its financial statements the benefit of a tax position taken (or expected to be taken) on an income tax return if such position will more likely than not be sustained upon examination based on the technical merits of the position. Based upon its review of tax positions, the Fund has determined that FIN 48 did not have a material impact on the Fund’s financial statements for the six months ended June 30, 2008.

3.	Fair Value Measurements — A summary of the value of the Fund’s investments as of June 30, 2008, based on the level of inputs used in accordance with SFAS 157 (Note 2a), is as follows:

Valuation Inputs		Value
Level 1 – Quoted Prices		$3,214,331,828
Level 2 – Other Significant Observable Inputs		336,126,000
Level 3 – Significant Unobservable Inputs		6,996,855
Total		$3,557,454,683

Notes to Financial Statements (unaudited)

As required by SFAS 157, the following is a reconciliation of investments for which significant unobservable inputs (Level 3) were used to determine the fair value of investments classified as Level 3 at either the beginning or end of the period:

Balance as of December 31, 2007	$	—
Net purchase		10,041,774
Net change in unrealized depreciation		(3,044,919	)
Balance as of June 30, 2008	$	6,996,855
Net change in unrealized depreciation from
investments still held as of June 30, 2008	$	(3,044,919	)

4.	Management Fee, Distribution Services, and Other Transactions — The Manager manages the affairs of the Fund and provides the necessary personnel and facilities. Compensation of all officers of the Fund, all directors of the Fund who are employees of the Manager, and all personnel of the Fund and the Manager is paid by the Manager. The Manager receives a fee, calculated daily and payable monthly, equal to 0.90% per annum of the first $3 billion of the Fund’s average daily net assets, 0.85% per annum of the next $3 billion of the Fund’s average daily net assets, and 0.75% per annum of the Fund’s average daily net assets in excess of $6 billion. The management fee reflected in the Statement of Operations represents 0.89% per annum of the Fund’s average daily net assets. (Note 14)

	For the six months ended June 30, 2008, Seligman Advisors, Inc. (the “Distributor”), agent for the distribution of the Fund’s shares and an affiliate of the Manager, received commissions and concessions of $129,811 from sales of Class A shares. Commissions of $779,787 were also paid to dealers for sales of Class A shares.

	The Fund has an Administration, Shareholder Services and Distribution Plan (the “Plan”) with respect to distribution of its shares. Under the Plan, with respect to Class A shares, service organizations can enter into agreements with the Distributor and receive a continuing fee of up to 0.25% on an annual basis, payable monthly, of the average daily net assets of the Class A shares attributable to the particular service organizations for providing personal services and/or the maintenance of shareholder accounts. The Distributor charges such fees to the Fund pursuant to the Plan. For the six months ended June 30, 2008, fees incurred under the Plan aggregated $3,145,732, or 0.25% per annum of the average daily net assets of Class A shares.

	Under the Plan, with respect to Class B shares, Class C shares, Class D shares (only through May 16, 2008), and Class R shares, service organizations can enter into agreements with the Distributor and receive a continuing fee for providing personal services and/or the maintenance of shareholder accounts of up to 0.25% on an annual basis of the average daily net assets of the Class B, Class C, Class D and Class R shares for which the organizations are responsible; and, for Class C, Class D and Class R shares, fees for providing other distribution assistance of up to 0.75% (0.25%, in the case of Class R shares) on an annual basis of such average daily net assets. Such fees are paid monthly by the Fund to the Distributor pursuant to the Plan.

	For the six months ended June 30, 2008, fees incurred under the Plan, equivalent to 1% per annum of the average daily net assets of Class B, Class C, and Class D shares (only through May 16, 2008), and 0.50% per annum of average daily net assets of Class R shares amounted to $1,040,430, $1,809,793, $1,802,453, and $62,637, respectively.

	The Distributor and Seligman Services, Inc., also an affiliate of the Manager, are eligible to receive distribution and service fees (12b-1) pursuant to the Plan. For the year ended December 31, 2007, the Distributor and Seligman Services, Inc. received distribution and service (12b-1) fees of $296,608.

	The Distributor is entitled to retain any CDSC imposed on certain redemptions of Class A, Class C, Class D (only through May 16, 2008), and Class R shares. For the six months ended June 30, 2008, such charges

Notes to Financial Statements (unaudited)

	amounted to $63,150. The Distributor has sold its rights to third parties to collect any CDSC imposed on redemptions of Class B shares. For the six months ended June 30, 2008, Seligman Data Corp., which is owned by certain associated investment companies, charged the Fund at cost $4,817,029, for shareholder account services in accordance with a methodology approved by the Fund’s directors. Class I shares receive more limited shareholder services than the Fund’s other classes of shares (the “Retail Classes”). Seligman Data Corp. does not allocate to Class I the costs of any of its departments that do not provide services to the Class I shareholders. Costs of Seligman Data Corp. directly attributable to the Retail Classes of the Fund were charged to those classes in proportion to their relative net asset values. Costs directly attributable to Class I shares were charged to Class I. The remaining charges were allocated to the Retail Classes and Class I by Seligman Data Corp. pursuant to a formula based on their net assets, shareholder transaction volumes and number of shareholder accounts. The Fund and certain other associated investment companies (together, the “Guarantors”) have severally but not jointly guaranteed the performance and observance of all the terms and conditions of two leases entered into by Seligman Data Corp., including the payment of rent by Seligman Data Corp. (the “Guaranties”). The leases and the related Guaranties expire in September 2008 and January 2019, respectively. The obligation of the Fund to pay any amount due under the Guaranties is limited to a specified percentage of the full amount, which generally is based on the Fund’s percentage of the expenses billed by Seligman Data Corp. to all Guarantors in the preceding calendar quarter. As of June 30, 2008, the Fund’s potential obligation under the Guaranties is $4,360,600. As of June 30, 2008, no event has occurred which would result in the Fund becoming liable to make any payment under the Guaranties. A portion of the rent paid by Seligman Data Corp. is charged to the Fund as part of Seligman Data Corp.’s shareholder account services cost. Certain officers and directors of the Fund are officers or directors of the Manager, the Distributor, Seligman Services, Inc., and/or Seligman Data Corp. The Fund has a compensation arrangement under which directors who receive fees may elect to defer receiving such fees. Directors may elect to have their deferred fees accrue interest or earn a return based on the performance of the Fund or other funds in the Seligman Group of Investment Companies. The cost of such fees and earnings/loss accrued thereon is included in directors’ fees and expenses and the accumulated balance thereof at June 30, 2008 of $24,864 is included in accrued expenses and other liabilities. Deferred fees and related accrued earnings are not deductible by the Fund for federal income tax purposes until such amounts are paid.

5.	Committed Line of Credit — The Fund is a participant in a joint $200 million committed line of credit that is shared by substantially all funds in the Seligman Group of Investment Companies. The directors have currently limited the Fund’s borrowings to 10% of its net assets. Borrowings pursuant to the credit facility are subject to interest at a rate equal to the overnight federal funds rate plus 0.50%. The Fund incurs a commitment fee of 0.12% per annum on its share of the unused portion of the credit facility. The credit facility may be drawn upon only for temporary purposes and is subject to certain other customary restrictions. The credit facility commitment expires in June 2009, but is renewable annually with the consent of the participating banks. For the six months ended June 30, 2008, the Fund did not borrow from the credit facility.

6.	Purchases and Sales of Securities — Purchases and sales of portfolio securities, excluding short-term investments, for the six months ended June 30, 2008, amounted to $2,723,707,586 and $3,139,255,038, respectively.

7.	Federal Tax Information — Certain components of income, expense and realized capital gain and loss are recognized at different times or have a different character for federal income tax purposes and for financial reporting purposes. Where such differences are permanent in nature, they are reclassified in the components of net assets based on their characterization for federal income tax purposes. Any such reclassifications will have no effect on net assets, results of operations or net asset value per share of the

Notes to Financial Statements (unaudited)

Fund. As a result of the differences described above, the treatment for financial reporting purposes of distributions made during the year from net investment income or net realized gains may differ from their treatment for federal income tax purposes. Further, the cost of investments also can differ for federal income tax purposes.

The tax basis information presented is based on operating results for the six months ended June 30, 2008, and will vary from the final tax information as of the Fund’s year end.

At June 30, 2008, the cost of investments for federal income tax purposes was $3,753,831,616. The tax basis cost was greater than the cost for financial reporting purposes primarily due to the tax deferral of losses on wash sales in the amount of $6,385,194.

The tax basis components of accumulated losses at June 30, 2008, are presented below.

Gross unrealized appreciation of portfolio securities*	$ 124,204,488
Gross unrealized depreciation of portfolio securities*	(320,557,678	)
Net unrealized depreciation of portfolio securities*	(196,353,190	)
Capital loss carryforwards	(12,308,398	)
Current period net realized loss	(87,122,803	)
Total accumulated losses	$(295,784,391	)

* Includes the effect of foreign currency transactions

	At December 31, 2007, the Fund had a capital loss carryforward for federal income tax purposes of $12,308,398, expiring in 2011, which is available for offset against future taxable net capital gains. The amount was determined after adjustments for certain differences between financial reporting and tax purposes, such as wash sale losses. Accordingly, no capital gain distributions are expected to be paid to shareholders until net capital gains have been realized in excess of the available capital loss carryforwards. There is no assurance that the Fund will be able to utilize all of its capital loss carryforward before it expires.

8.	Options Written — Transactions in options written for the six months ended June 30, 2008, were as follows:

	Shares Subject
	To Call		Premiums
Options outstanding, December 31, 2007	341,500		$	3,537,349

12.	Other Matters — In late 2003, the Manager conducted an extensive internal review concerning mutual fund trading practices. The Manager’s review, which covered the period 2001-2003, noted one arrangement that permitted frequent trading in certain open-end registered investment companies managed by the Manager (the “Seligman Funds”); this arrangement was in the process of being closed down by the Manager before September 2003. The Manager identified three other arrangements that permitted frequent trading, all of which had been terminated by September 2002. In January 2004, the Manager, on a voluntary basis, publicly disclosed these four arrangements to its clients and to shareholders of the Seligman Funds. The Manager also provided information concerning mutual fund trading practices to the SEC and the Office of the Attorney General of the State of New York (“NYAG”).

	In September 2005, the New York staff of the SEC indicated that it was considering recommending to the Commissioners of the SEC the instituting of a formal action against the Manager and the Distributor relating to frequent trading in the Seligman Funds. The Manager responded to the staff in October 2005 that it believed that any action would be both inappropriate and unnecessary, especially in light of the fact that the Manager had previously resolved the underlying issue with the Independent Directors of the Seligman Funds and made recompense to the affected Seligman Funds.

	In September 2006, the NYAG commenced a civil action in New York State Supreme Court against the Manager, the Distributor, Seligman Data Corp. and Brian T. Zino (collectively, the “Seligman Parties”), alleging, in substance, that, in addition to the four arrangements noted above, the Seligman Parties permitted other persons to engage in frequent trading and, as a result, the prospectus disclosure used by the registered investment companies managed by the Manager is and has been misleading. The NYAG included other related claims and also claimed that the fees charged by the Manager to the Seligman Funds were excessive. The NYAG is seeking damages of at least $80 million and restitution, disgorgement, penalties and costs and injunctive relief. The Seligman Parties answered the complaint in December 2006 and believe that the claims are without merit.

	Any resolution of these matters may include the relief noted above or other sanctions or changes in procedures. Any damages would be paid by the Manager and not by the Seligman Funds. If the NYAG obtains injunctive relief, the Manager and its affiliates could, in the absence of the SEC in its discretion granting exemptive relief, be enjoined from providing advisory and underwriting services to the Seligman Funds and other registered investment companies.

	The Manager does not believe that the foregoing legal action or other possible actions will have a material adverse impact on the Manager or its clients, including the Seligman Funds and other investment companies managed by it; however, there can be no assurance of this or that these matters and any related publicity will not affect demand for shares of the Seligman Funds and such other investment companies or have other adverse consequences.

13.	Recently Issued Accounting Pronouncement — In March 2008, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 161 (“SFAS 161”), “Disclosures about Derivative Instruments and Hedging Activities.” SFAS 161 requires enhanced disclosures about the Fund’s derivative and hedging activities, including how such activities are accounted for and their effect on the Fund’s financial position, performance and cash flows. SFAS 161 is effective for fiscal years beginning after November 15, 2008. The Fund is currently evaluating the impact of the adoption of SFAS 161 on the Fund’s financial statements and related disclosures.

14.	Subsequent Events — On July 7, 2008, Ameriprise Financial, Inc. (“Ameriprise”) announced an agreement to acquire the Manager in a transaction that is likely to close in the fourth quarter of 2008. Under the 1940 Act, consummation of Ameriprise’s acquisition of the Manager will result in the Manager becoming a wholly-owned subsidiary of RiverSource Investments, LLC (“RiverSource”), a subsidiary of Ameriprise, and a change of control of the Manager and an assignment and automatic termination of the Fund’s management agreement with the Manager. On July 29, 2008, the Fund’s Board approved a new advisory agreement with RiverSource, and a new administration agreement with Ameriprise. The new advisory agreement will be presented to the shareholders of the Fund for their approval.
