The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by visiting tricontinental.com. Returns reflect changes in market price or net asset value, as applicable, and assume reinvestment of distributions. Returns do not reflect the deduction of taxes that investors may pay on distributions or the sale of shares. The indices and the average do not reflect the effects of sales charges, expenses (excluding Lipper) and taxes. It is not possible to invest directly in an index or an average. -------------------------------------------------------------------------------- 2 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- (1) The Standard & Poor's 500 Composite Stock Price Index (S&P 500 Index), an unmanaged index of common stocks, is frequently used as a general measure of market performance. The index reflects reinvestment of all distributions and changes in market prices. (2) The Lipper Large-Cap Core Funds Index (the Lipper Index) includes the 30 largest open-end large-cap core funds tracked by Lipper Inc. The Lipper Index's returns include net reinvested distributions.* (3) The Lipper Large-Cap Core Funds Average (the Lipper Average) includes open- end funds that, by portfolio practice, invest at least 75% of their assets in companies with market capitalizations (on a three-year weighted basis) above Lipper's U.S. Diversified Equity large-cap floor (which is calculated by adding the capitalization weight of each stock in the Russell 3000 Index, in descending order of market cap, until the 70(th) percentile of the total capitalization is reached). Large-cap core funds typically have an average price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share growth value relative to the S&P 500 Index. The Lipper Average's returns include net reinvested distributions.* *On Oct. 1, 2009 the Lipper Index replaced the Lipper Average as the Fund's secondary benchmark. The Lipper Average includes all funds categorized by Lipper within the broad universe of open-end funds in the Lipper Average, whereas the Lipper Index includes only a select group of open-end funds from the Lipper Average, as described above. This change was made to bring the selection of the secondary benchmark in line with the practice of the Fund Family, which would permit a common stockholder experience and provide a more focused peer group for performance comparison purposes. Information on both the Lipper Index and the Lipper Average will be included for a one-year transition period. Thereafter, only the Lipper Index will be included. Although the Fund is a closed-end fund, the Lipper Index and the Lipper Average are included because they provide a broader competitor base than the equivalent Lipper closed-end universes. -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 3 YOUR FUND AT A GLANCE (continued) ---------------------------------------------- PRICE PER SHARE -------------------------------------------------------------------------------- JUNE 30, 2010 MARCH 31, 2010 DEC. 31, 2009 ---------------------------------------------------------------------------- Market price $10.87 $12.27 $11.52 ---------------------------------------------------------------------------- Net asset value 12.95 14.53 13.73 ---------------------------------------------------------------------------- DISTRIBUTIONS PAID PER COMMON SHARE(A) -------------------------------------------------------------------------------- PAYABLE DATE PER SHARE AMOUNT ----------------------------------------------------------------- March 29, 2010 $0.04 ----------------------------------------------------------------- June 21, 2010 0.05 ----------------------------------------------------------------- (a) Preferred Stockholders were paid dividends totaling $1.25 per share.

In addition, investments shall be disclosed by major category. The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund's assumptions about the information market participants would use in pricing an investment. An investment's level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset or liability's fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market. Fair value inputs are summarized in the three broad levels listed below: - Level 1 -- Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments. - Level 2 -- Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.). - Level 3 -- Valuations based on significant unobservable inputs (including the Fund's own assumptions and judgment in determining the fair value of investments). Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Fund Administrator, along with any other relevant factors in the calculation of an investment's fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy. Non-U.S. equity securities actively traded in foreign markets may be reflected in Level 2 despite the availability of closing prices, because the Fund evaluates and determines whether those closing prices reflect fair value at the close of the New York Stock Exchange (NYSE) or require adjustment, as described in Note 2 to the financial statements -- Valuation of securities. Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 15 PORTFOLIO OF INVESTMENTS (continued) ------------------------------------------- FAIR VALUE MEASUREMENTS (CONTINUED) Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models rely on one or more significant unobservable inputs and/or significant assumptions by the Fund Administrator. Inputs used in a valuation model may include, but are not limited to, financial statement analysis, discount rates and estimated cash flows, and comparable company data. The following table is a summary of the inputs used to value the Fund's investments as of June 30, 2010: FAIR VALUE AT JUNE 30, 2010 ------------------------------------------------------------------ LEVEL 1 LEVEL 2 QUOTED PRICES OTHER LEVEL 3 IN ACTIVE SIGNIFICANT SIGNIFICANT MARKETS FOR OBSERVABLE UNOBSERVABLE DESCRIPTION(A) IDENTICAL ASSETS(B) INPUTS INPUTS TOTAL ---------------------------------------------------------------------------------------------- Equity Securities Common Stocks $908,296,448 $-- $-- $908,296,448 ---------------------------------------------------------------------------------------------- Total Equity Securities 908,296,448 -- -- 908,296,448 ---------------------------------------------------------------------------------------------- Other Limited Partnerships -- -- 1,720,272 1,720,272 Investments of Cash Collateral Received for Securities on Loan -- 67,647,103 -- 67,647,103 ---------------------------------------------------------------------------------------------- Total Other -- 67,647,103 1,720,272 69,367,375 ---------------------------------------------------------------------------------------------- Investments in Securities 908,296,448 67,647,103 1,720,272 977,663,823 Other Financial Instruments(c) (11,741) -- -- (11,741) ---------------------------------------------------------------------------------------------- Total $908,284,707 $67,647,103 $1,720,272 $977,652,082 ---------------------------------------------------------------------------------------------- (a) See the Portfolio of Investments for all investment classifications not indicated in the table.

Generally, the per share amounts are derived by converting the actual dollar amounts incurred for each item, as disclosed in the financial statements, to their equivalent per Common share amounts, using average Common shares outstanding during the period. Total return measures the Fund's performance assuming that investors purchased shares of the Fund at the market price or net asset value as of the beginning of the period, invested all distributions paid, as provided for in the Fund's Prospectus and Automatic Dividend Investment and Cash Purchase Plan, and then sold their shares at the closing market value or net asset value per share on the last day of the period. The computations do not reflect any sales charges or transaction costs on your investment or taxes investors may incur on distributions or on the sale of shares of the Fund, and are not annualized for periods of less than one year. The ratios of expenses and net investment income to average net assets for Common Stock for the periods presented do not reflect the effect of dividends paid to Preferred Stockholders. -------------------------------------------------------------------------------- 22 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- SIX MONTHS YEAR ENDED DEC. 31, ENDED JUNE 30, ------------------------------------------------------- PER SHARE OPERATING PERFORMANCE 2010 2009 2008 2007 2006 2005 (UNAUDITED) Net asset value, beginning of period $13.73 $11.29 $23.03 $25.66 $22.16 $21.87 ------------------------------------------------------------------------------------------------------------------------------ INCOME FROM INVESTMENT OPERATIONS: Net investment income (loss) .12 .20 .52 .84 .33 .26 Net gains (losses) (both realized and unrealized) (.81) 2.42 (9.88) (1.01) 3.47 .29 ------------------------------------------------------------------------------------------------------------------------------ Increase (decrease) from investment operations (.69) 2.62 (9.36) (.17) 3.80 .55 ------------------------------------------------------------------------------------------------------------------------------ LESS: Dividends paid on Preferred Stock (.01) (.03) (.02) (.02) (.02) (.02) Dividends paid on Common Stock (.08) (.17) (.50) (.87) (.28) (.24) Distributions from realized gains -- -- (.39) (1.57) -- -- Distributions from return of capital -- (.02) (1.22) -- -- -- Issuance of Common Stock in distributions -- -- (.25) -- -- -- ------------------------------------------------------------------------------------------------------------------------------ Total distributions (.09) (.22) (2.38) (2.46) (.30) (.26) ------------------------------------------------------------------------------------------------------------------------------ Payment from affiliate -- .04 -- -- -- -- ------------------------------------------------------------------------------------------------------------------------------ Net asset value, end of period $12.95 $13.73 $11.29 $23.03 $25.66 $22.16 ------------------------------------------------------------------------------------------------------------------------------ Adjusted net asset value, end of period(a) $12.91 $13.69 $11.26 $22.98 $25.60 $22.10 Market price, end of period $10.87 $11.52 $9.86 $20.90 $22.38 $18.58 ------------------------------------------------------------------------------------------------------------------------------ TOTAL RETURN Based upon net asset value (4.93%) 24.11%(b) (43.77%) (.52%) 17.38% 2.66% Based upon market price (4.89%) 19.24% (45.89%) 3.51% 22.10% 2.98% ------------------------------------------------------------------------------------------------------------------------------ RATIOS TO AVERAGE NET ASSETS Expenses to average net assets for Common Stock .62%(c) .98% .73% .66% .80% .65% Net investment income to average net assets for Common Stock 1.85%(c) 1.46% 2.96% 3.22% 1.40% 1.20% ------------------------------------------------------------------------------------------------------------------------------ SUPPLEMENTAL DATA NET ASSETS, END OF PERIOD (IN MILLIONS): For Common Stock $879 $946 $894 $2,373 $2,657 $2,392 For Preferred Stock 38 38 38 38 38 38 ------------------------------------------------------------------------------------------------------------------------------ TOTAL NET ASSETS $917 $984 $932 $2,411 $2,695 $2,430 ------------------------------------------------------------------------------------------------------------------------------ Portfolio turnover rate 49% 70% 111% 123% 122% 71% ------------------------------------------------------------------------------------------------------------------------------ (a) Assumes the exercise of outstanding warrants.

ORGANIZATION Tri-Continental Corporation (the Fund) is registered under the Investment Company Act of 1940, as amended (1940 Act), as a diversified, closed-end management investment company. The Fund has 1 million authorized shares of preferred capital stock (Preferred Stock) and 159 million authorized shares of common stock (Common Stock) which trades primarily on the New York Stock Exchange (NYSE) under the symbol "TY". The Fund invests primarily for the longer term and its objective is to produce future growth of both capital and income while providing reasonable current income. Tri-Continental Corporation's Preferred Stock is entitled to two votes and the Common Stock is entitled to one vote per share at all meetings of Stockholders. In the event of a default in payments of dividends on the Preferred Stock equivalent to six quarterly dividends, the Preferred Stockholders are entitled, voting separately as a class to the exclusion of Common Stockholders, to elect two additional directors, such right to continue until all arrearages have been paid and current Preferred Stock dividends are provided for. Generally, the vote of Preferred Stockholders is required to approve certain actions adversely affecting their rights. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES USE OF ESTIMATES Preparing financial statements that conform to U.S. generally accepted accounting principles requires management to make estimates (e.g., on assets, liabilities and contingent assets and liabilities) that could differ from actual results. VALUATION OF SECURITIES All securities are valued at the close of business of the NYSE. Securities traded on national securities exchanges or included in national market systems are valued at the last quoted sales price from the primary exchange. Debt securities are generally traded in the over-the-counter market and are valued by an independent pricing service using an evaluated bid. When market quotes are not readily available, the pricing service, in determining fair values of debt securities, takes into consideration such factors as current quotations by broker/dealers, coupon, maturity, quality, type of issue, trading characteristics, and other yield and risk factors it deems relevant in determining valuations. Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. The procedures adopted by the Fund's Board of Directors -------------------------------------------------------------------------------- 24 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- (the Board) generally contemplate the use of fair valuation in the event that price quotations or valuations are not readily available, price quotations or valuations from other sources are not reflective of market value and thus deemed unreliable, or a significant event has occurred in relation to a security or class of securities (such as foreign securities) that is not reflected in price quotations or valuations from other sources. A fair value price is a good faith estimate of the value of a security at a given point in time. Many securities markets and exchanges outside the U.S. close prior to the close of the NYSE and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE, including significant movements in the U.S. market after foreign exchanges have closed. Accordingly, in those situations, Ameriprise Financial, Inc. (Ameriprise Financial), parent company of Columbia Management Investment Advisers, LLC (formerly known as RiverSource Investments, LLC) (the Investment Manager), as administrator to the Fund, will fair value foreign securities pursuant to procedures adopted by the Board, including utilizing a third party pricing service to determine these fair values. These procedures take into account multiple factors, including movements in the U.S. securities markets, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the NYSE. The fair value of a security is likely to be different from the quoted or published price, if available. Short-term securities maturing in more than 60 days from the valuation date are valued at the market price or approximate market value based on current interest rates. Typically, those maturing in 60 days or less that originally had maturities of more than 60 days at acquisition date are valued at amortized cost using the market value on the 61(st) day before maturity. Short-term securities maturing in 60 days or less at acquisition date are valued at amortized cost. Amortized cost is an approximation of market value. Investments in money market funds are valued at net asset value. FOREIGN CURRENCY TRANSLATIONS Securities and other assets and liabilities denominated in foreign currencies are translated daily into U.S. dollars. Foreign currency amounts related to the purchase or sale of securities and income and expenses are translated at the exchange rate on the transaction date. The effect of changes in foreign exchange rates on realized and unrealized security gains or losses is reflected as a component of such gains or losses. In the Statement of Operations, net realized gains or losses from foreign currency transactions, if any, may arise from sales of foreign currency, closed forward contracts, exchange gains or losses realized between the trade date and settlement date on securities transactions, and other -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 25 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- translation gains or losses on dividends, interest income and foreign withholding taxes. 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 agreement, must have an aggregate market value greater than or equal to the repurchase price plus accrued interest at all times. The market value of securities held as collateral for repurchase agreements is monitored on a daily basis to ensure the existence of the proper level of collateral. ILLIQUID SECURITIES At June 30, 2010, investments in securities included issues that are illiquid which the Fund currently limits to 15% of net assets, at market value, at the time of purchase. The aggregate value of such securities at June 30, 2010 was $1,720,272 representing 0.19% of net assets. Certain illiquid securities may be valued, in good faith, by management at fair value according to procedures approved by the Board. According to Board guidelines, certain unregistered securities are determined to be liquid and are not included within the 15% limitation specified above. Assets are liquid if they can be sold or disposed of in the ordinary course of business within seven days at approximately the value at which the asset is valued by the Fund. PAYMENT FROM AFFILIATE During the year ended Dec. 31, 2009, the Investment Manager voluntarily reimbursed the Fund $3,120,206 for a loss on a trading error. GUARANTEES AND INDEMNIFICATIONS Under the Fund's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, certain of the Fund's contracts with its service providers contain general indemnification clauses. The Fund's maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined and the Fund has no historical basis for predicting the likelihood of any such claims. FEDERAL TAXES The Fund's policy is to comply with Subchapter M of the Internal Revenue Code that applies to regulated investment companies and to distribute substantially all of its taxable income (which includes net short-term capital gains) to Stockholders. No provision for income or excise taxes is thus required. -------------------------------------------------------------------------------- 26 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- Management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Generally, the tax authorities can examine all tax returns filed for the last three years. FOREIGN CAPITAL GAINS TAXES Realized gains in certain countries may be subject to foreign taxes at the fund level, at rates ranging from approximately 10% to 15%. The Fund pays such foreign taxes on net realized gains at the appropriate rate for each jurisdiction. DIVIDENDS TO STOCKHOLDERS The Fund has an earned distribution policy. Under this policy, the Fund intends to make quarterly distributions to holders of Common Stock that are approximately equal to net investment income, less dividends payable on the Fund's Preferred Stock. Capital gains, when available, are distributed to Common Stockholders along with the last income dividend of the calendar year. Dividends and other distributions to Stockholders are recorded on ex-dividend dates. OTHER Security transactions are accounted for on the date securities are purchased or sold. Dividend income is recognized on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities. Interest income, including amortization of premium, market discount and original issue discount using the effective interest method, is accrued daily. 3. INVESTMENTS IN DERIVATIVES The Fund may invest in certain derivative instruments, which are transactions whose values depend on or are derived from (in whole or in part) the value of one or more other assets, such as securities, currencies, commodities or indices. Such derivative instruments may be used to maintain cash reserves while maintaining exposure to certain other assets, to offset anticipated declines in values of investments, to facilitate trading, to reduce transaction costs, and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk, and credit risk. Investments in derivative instruments may expose the Fund to certain additional risks, including those detailed below. FUTURES TRANSACTIONS The Fund may buy and sell financial futures contracts traded on any U.S. or foreign exchange to produce incremental earnings, hedge existing positions or protect against market changes in the value of equities, interest rates or foreign -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 27 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- currencies. The Fund may also buy and write put and call options on these futures contracts. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date. Futures and options on futures are valued daily based upon the last sale price at the close of the market on the principal exchange on which they are traded. Upon entering into a futures contract, the Fund is required to deposit either cash or securities in an amount (initial margin) equal to a certain percentage of the contract value. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily changes in the contract value and are recorded as unrealized gains and losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Upon entering into futures contracts, the Fund bears the risk of interest rates, exchange rates or securities prices moving unexpectedly, in which case, the Fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying securities. OPTION TRANSACTIONS The Fund may buy and write options traded on any U.S. or foreign exchange, or in the over-the-counter (OTC) market to produce incremental earnings, protect gains, and facilitate buying and selling of securities for investments. The Fund may also buy and sell put and call options and write covered call options on portfolio securities. Options are contracts which entitle the holder to purchase or sell securities or other financial instruments at a specified price, or in the case of index options, to receive or pay the difference between the index value and the strike price of the index option. Completion of transactions for options traded in the OTC market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain OTC options trades. Cash collateral held or posted by the Fund for such option trades must be returned to the counterparty or the Fund upon closure, exercise or expiration of the contract. Option contracts purchased are recorded as investments and options contracts written are recorded as liabilities of the Fund. Option contracts are valued daily at the closing prices on their primary exchanges and unrealized appreciation or depreciation is recorded. Option contracts, including OTC option contracts, with no readily available market value are valued using quotations obtained from independent brokers as of the close of the NYSE. The Fund will realize a gain or loss when the option transaction expires or is exercised. When options on debt securities or futures are exercised, the Fund will realize a gain or loss. When -------------------------------------------------------------------------------- 28 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- other options are exercised, the proceeds on sales for a written call option, the purchase cost for a written put option or the cost of a security for a purchased put or call option is adjusted by the amount of premium received or paid. The risk in buying an option is that the Fund pays a premium whether or not the option is exercised. The Fund also has the additional risk of being unable to enter into a closing transaction if a liquid secondary market does not exist. The risk in writing a call option is that the Fund gives up the opportunity for profit if the market price of the security increases. The risk in writing a put option is that the Fund may incur a loss if the market price of the security decreases and the option is exercised. The Fund's maximum payout in the case of written put option contracts represents the maximum potential amount of future payments (undiscounted) that the Fund could be required to make as a guarantor for written put options. The maximum payout amount may be offset by the subsequent sale, if any, of assets obtained upon the exercise of the put options by holders of the option contracts or proceeds received upon entering into the contracts. For OTC options contracts, the transaction is also subject to counterparty credit risk. At June 30, 2010, and for the six months then ended, the Fund had no written or purchased options. EFFECTS OF DERIVATIVE TRANSACTIONS ON THE FINANCIAL STATEMENTS The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; the impact of derivative transactions on the Fund's operations over the period including realized gains or losses and unrealized gains or losses. The derivative schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.

The monthly average gross notional amount for long contracts was $2.6 million for the six months ended June 30, 2010. The fair value of such contracts at June 30, 2010 is set forth in the table above. 4. EXPENSES INVESTMENT MANAGEMENT SERVICES FEES Under an Investment Management Services Agreement, the Investment Manager determines on behalf of the Fund which securities will be purchased, held or sold. The management fee charged by the Investment Manager is 0.355% of the Fund's average daily net assets. ADMINISTRATIVE SERVICES FEES Under an Administrative Services Agreement, the Fund pays Ameriprise Financial an annual fee for administration and accounting services equal to a percentage of the Fund's average daily net assets that declines from 0.06% to 0.03% as the Fund's net assets increase The fee for the six months ended June 30, 2010 was 0.06% of the Fund's average daily net assets. OTHER FEES Other expenses are for, among other things, certain expenses of the Fund or the Board including: Fund boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. Payment of these Fund and Board expenses is facilitated by a company providing limited administrative services to the Fund and the Board. For the six months ended June 30, 2010, other expenses paid to this company were $346. -------------------------------------------------------------------------------- 30 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- COMPENSATION OF BOARD MEMBERS Under a Deferred Compensation Plan (the Plan), the board members who are not "interested persons" of the Fund under the 1940 Act may defer receipt of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of the Fund or other RiverSource, Seligman and Threadneedle funds. The Fund's liability for these amounts is adjusted for market value changes and remains in the funds until distributed in accordance with the Plan. STOCKHOLDER SERVICING FEES Under a Stockholder Service Agent Agreement, Columbia Management Investment Services Corp. (formerly known as RiverSource Service Corporation) (the Stockholder Servicing Agent) maintains Fund Stockholder accounts and records and provides Fund Stockholder services. Under the Agreement, the Fund pays the Stockholder Servicing Agent a fee equal to 0.10% of the average daily net assets of the Fund's shares of Common Stock. 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 a lease entered into by Seligman Data Corp. (SDC), the Fund's former Stockholder servicing agent, including the payment of rent by SDC (the Guaranty). The lease and the Guaranty expire in January 2019. At June 30, 2010, the Fund's total potential future obligation over the life of the Guaranty is $1,140,700. The liability remaining at June 30, 2010 for Non-Recurring Charges amounted to $583,674 and is included within other accrued expenses in the Statement of Assets and Liabilities. SDC is owned by six associated investment companies, including the Fund. The Fund's ownership interest in SDC at June 30, 2010 is included in other assets in the Statement of Assets and Liabilities at a cost of $43,681. 5. SECURITIES TRANSACTIONS Cost of purchases and proceeds from sales of securities (other than short-term obligations) aggregated $479,491,474 and $489,488,901, respectively, for the six months ended June 30, 2010. Realized gains and losses are determined on an identified cost basis. 6. CAPITAL STOCK TRANSACTIONS Under the Fund's Charter, dividends on Common Stock cannot be declared unless net assets, after deducting the amount of such dividends and all unpaid dividends declared on Preferred Stock, equal at least $100 per share of Preferred Stock outstanding. The Preferred Stock is subject to redemption at the Fund's -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 31 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- option at any time on 30 days' notice at $55 per share (or a total of $41,400,700 for the shares outstanding) plus accrued dividends, and entitled in liquidation to $50 per share plus dividends accrued or in arrears, as the case may be. AUTOMATIC DIVIDEND AND CASH PURCHASE PLAN The Fund, in connection with its Automatic Dividend Investment and Cash Purchase Plan and other Stockholder plans, acquires and issues shares of its own Common Stock, as needed, to satisfy Plan requirements. For the six months ended June 30, 2010, the Fund purchased 883,442 shares of Common Stock from Plan participants at a cost of $10,493,401, which represented a weighted average discount of 15.3% from the net asset value of those acquired shares. A total of 84,865 shares were issued to Plan participants during the period for proceeds of $976,735, a weighted average discount of 15.9% from the net asset value of those shares. In addition, a total of 194,535 shares were issued at market price in distributions during the period for proceeds of $2,308,102, a weighted average discount of 15.4% from the net asset value of those shares. For Stockholder accounts established after June 1, 2007, unless the Stockholder Servicing Agent is otherwise instructed by the Stockholder, distributions on the Common Stock are paid in book shares of Common Stock which are entered in the Stockholder's account as "book credits." Each Stockholder may also elect to receive distributions 75% in shares and 25% in cash, 50% in shares and 50% in cash, or 100% in cash. Any such election must be received by the Stockholder Servicing Agent by the record date for a distribution. If the Stockholder holds shares of Common Stock through a financial intermediary (such as a broker), the Stockholder should contact the financial intermediary to discuss reinvestment and distribution options. Elections received after a record date for a distribution will be effective in respect of the next distribution. Shares issued to the Stockholder in respect of distributions will be at a price equal to the lower of: (i) the closing sale price of the Common Stock on the NYSE on the ex-dividend date or (ii) the greater of net asset value per share of Common Stock and 95% of the closing price of the Common Stock on the NYSE on the ex- dividend date. The issuance of Common Stock at less than net asset value per share will dilute the net asset value of all Common Stock outstanding at that time. For the six months ended June 30, 2010, the Fund purchased 412,702 shares of its Common Stock in the open market at an aggregate cost of $4,970,065, which represented a weighted average discount of 15.5% from the net asset value of those acquired shares. Shares of Common Stock repurchased to satisfy Plan requirements or in the open market are retired and no longer outstanding. Under the Fund's stock repurchase program for 2009, the amount of the Fund's outstanding Common Stock that the Fund may repurchase from Stockholders and -------------------------------------------------------------------------------- 32 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- in the open market is 5%, provided that, with respect to shares purchased in the open market, the discount must be greater than 10%. The intent of the stock repurchase program is, among other things, to moderate the growth in the number of shares outstanding, increase the NAV of the Fund's outstanding shares, reduce the dilutive impact on stockholders who do not take capital gain distributions in additional shares and increase the liquidity of the Fund's Common Stock in the marketplace. WARRANTS At June 30, 2010, the Fund reserved 229,587 shares of Common Stock for issuance upon exercise of 9,491 Warrants, each of which entitled the holder to purchase 24.19 shares of Common Stock at $0.93 per share. Assuming the exercise of all Warrants outstanding at June 30, 2010, net assets would have increased by $213,516 and the net asset value of the Common Stock would have been $12.91 per share. The number of Warrants exercised during the six months ended June 30, 2010 and for the year ended Dec. 31, 2009 was 0 and 500, respectively. CASH TENDER OFFER The Fund conducted a cash tender offer for up to 12.5% of its issued and outstanding shares of Common Stock, which expired on Feb. 11, 2009. The number of shares of Common Stock that were tendered through the expiration date was 9,247,000 (or approximately 11.7% of the Fund's Common Stock outstanding). Because less than 12.5% of the issued and outstanding shares of Common Stock of the Fund was tendered through the expiration date, all properly tendered shares were accepted for purchase. The purchase price was equal to 99.25% of the net asset value per share of the Fund's Common Stock as of the close of the regular trading session of the NYSE on Feb. 12, 2009. The total value of the Common Stock shares purchased was $93,024,820, which was paid in cash. 7. LENDING OF PORTFOLIO SECURITIES The Fund has entered into a Master Securities Lending Agreement (the Agreement) with JPMorgan Chase Bank, National Association (JPMorgan). The Agreement authorizes JPMorgan as lending agent to lend securities to authorized borrowers in order to generate additional income on behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured by cash or U.S. government securities equal to at least 100% of the market value of the loaned securities. Any additional collateral required to maintain those levels due to market fluctuations of the loaned securities is delivered the following business day. Cash collateral received is invested by the lending agent on behalf of the Fund into -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 33 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- authorized investments pursuant to the Agreement. The investments made with the cash collateral are listed in the Portfolio of Investments. The values of such investments and any uninvested cash collateral are disclosed in the Statement of Assets and Liabilities along with the related obligation to return the collateral upon the return of the securities loaned. At June 30, 2010, securities valued at $64,471,043 were on loan, secured by cash collateral of $67,647,103 and secured by U.S. government securities valued at $28,468 invested in short-term securities or in cash equivalents. Risks of delay in recovery of securities or even loss of rights in the securities may occur should the borrower of the securities fail financially. Risks may also arise to the extent that the value of the securities loaned increases above the value of the collateral received. JPMorgan will indemnify the Fund from losses resulting from a borrower's failure to return a loaned security when due. Such indemnification does not extend to losses associated with declines in the value of cash collateral investments. Loans are subject to termination by the Fund or the borrower at any time, and are, therefore, not considered to be illiquid investments. Pursuant to the Agreement, the Fund receives income for lending its securities either in the form of fees or by earning interest on invested cash collateral, net of negotiated rebates paid to borrowers and fees paid to the lending agent for services provided and any other securities lending expenses. Net income of $141,322 earned from securities lending for the six months ended June 30, 2010, is included in the Statement of Operations. The Fund also continues to earn interest and dividends on the securities loaned. 8. AFFILIATED MONEY MARKET FUND The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund, a money market fund established for the exclusive use of RiverSource, Seligman and Threadneedle funds and other institutional clients of the Investment Manager. The cost of the Fund's purchases and proceeds from sales of shares of RiverSource Short-Term Cash Fund aggregated $18,332,549 and $22,247,909, respectively, for the six months ended June 30, 2010. The income distributions received with respect to the Fund's investment in RiverSource Short-Term Cash Fund can be found in the Statement of Operations. 9. LEHMAN BROTHERS HOLDINGS INC. EQUITY-LINKED NOTES The Fund holds investments in two equity-linked notes (notes) for which Lehman Brothers Holdings Inc. (Lehman Brothers) is the counterparty. The notes (with an aggregate principal amount of $29.7 million) defaulted as of their respective -------------------------------------------------------------------------------- 34 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- maturity dates, Sept. 14, 2008 and Oct. 2, 2008. Lehman Brothers filed a Chapter 11 bankruptcy petition on Sept. 15, 2008, and as such, it is likely that the Fund will receive less than the maturity value of the notes, pending the outcome of the bankruptcy proceedings. Based on the bankruptcy proceedings, the Fund recorded receivables aggregating $2.9 million based on the estimated amounts recoverable for the notes and recognized realized losses of $26.8 million. The estimates of the amounts recoverable for the notes are periodically adjusted by the Investment Manager based on the observable trading price of Lehman Brothers senior notes, which provide an indication of amounts recoverable through the bankruptcy proceedings. Any changes to the receivable balances resulting from such adjustments are recorded as a component of interest income in the Statement of Operations. At June 30, 2010, the value of the receivable balances were $4.3 million, which represented 0.46% of the Fund's net assets. The receivable balances for the notes are reported as other receivables in the Statement of Assets and Liabilities. 10. FEDERAL TAX INFORMATION Net investment income (loss) and net realized gains (losses) may differ for financial statement and tax purposes primarily because of futures and options contracts, passive foreign investment company (PFIC) holdings, re- characterization of real estate investment trust (REIT) distributions, investments in partnerships, post-October losses and losses deferred due to wash sales. The character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. Also, due to the timing of dividend distributions, the fiscal year in which amounts are distributed may differ from the year that the income or realized gains were recorded by the Fund. For federal income tax purposes, the Fund had a capital loss carry-over of $774,327,301 at Dec. 31, 2009, that if not offset by capital gains, will expire as follows: 2016 2017 $217,818,494 $556,508,807 Because the measurement periods for a regulated investment company's income are different for excise tax purposes versus income tax purposes, special rules are in place to protect the amount of earnings and profits needed to support excise tax distributions. As a result, the Fund is permitted to treat net capital losses realized between Nov. 1, 2009 and its fiscal year end (post-October loss) as occurring on the first day of the following tax year. At Dec. 31, 2009, the Fund -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 35 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- had a post-October loss of $945,335 that is treated for income tax purposes as occurring on Jan. 1, 2010. It is unlikely the Board will authorize a distribution of any net realized capital gains until the available capital loss carry-over has been offset or expires. There is no assurance that the Fund will be able to utilize all of its capital loss carry-over before it expires. 11. RISKS RELATING TO CERTAIN INVESTMENTS To the extent that the Fund invests a substantial percentage of its assets in an industry, the Fund's performance may be negatively affected if that industry falls out of favor. Stocks of large-capitalization companies have at times experienced periods of volatility and negative performance. During such periods, the value of such stocks may decline and the Fund's performance may be negatively affected. 12. SUBSEQUENT EVENTS Management has evaluated Fund related events and transactions that occurred during the period from the date of the Statement of Assets and Liabilities through the date of issuance of the Fund's financial statements. There were no events or transactions that occurred during the period that materially impacted the amounts or disclosures in the Fund's financial statements. 13. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc. was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company (now known as RiverSource) mutual funds and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota (the District Court). In response to defendants' motion to dismiss the complaint, the District Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Defendants moved for summary judgment in April 2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit) on -------------------------------------------------------------------------------- 36 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary judgment and remanded to the District Court for further proceedings. On August 6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the Supreme Court), asking the Supreme Court to stay the District Court proceedings while the Supreme Court considers and rules in a case captioned Jones v. Harris Associates, which involves issues of law similar to those presented in the Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v. Harris Associates and on April 5, 2010, the Supreme Court vacated the Eighth Circuit's decision in the Gallus case and remanded the case to the Eighth Circuit for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the Gallus case to the District Court for further consideration in light of the Supreme Court's decision in Jones v. Harris Associates. In December 2005, without admitting or denying the allegations, American Express Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc. (Ameriprise Financial), entered into settlement agreements with the Securities and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC) related to market timing activities. As a result, AEFC was censured and ordered to cease and desist from committing or causing any violations of certain provisions of the Investment Advisers Act of 1940, the Investment Company Act of 1940, and various Minnesota laws. AEFC agreed to pay disgorgement of $10 million and civil money penalties of $7 million. AEFC also agreed to retain an independent distribution consultant to assist in developing a plan for distribution of all disgorgement and civil penalties ordered by the SEC in accordance with various undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. Ameriprise Financial and its affiliates have cooperated with the SEC and the MDOC in these legal proceedings, and have made regular reports to the RiverSource, Seligman and Threadneedle funds' Boards of Directors/Trustees. Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Funds are not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as necessary, 8-K filings with the Securities and Exchange Commission on legal and regulatory matters that relate to Ameriprise -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 37 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov. There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased fund redemptions, reduced sale of fund shares or other adverse consequences to the funds. Further, although we believe proceedings are not likely to have a material adverse effect on the funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the funds, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial. -------------------------------------------------------------------------------- 38 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT -------------------------- Columbia Management Investment Advisers, LLC ("Columbia Management" or the "investment manager"), formerly known as RiverSource Investments, LLC, a wholly- owned subsidiary of Ameriprise Financial, Inc. ("Ameriprise Financial"), serves as the investment manager to the Fund. Under an investment management services agreement (the "IMS Agreement"), Columbia Management provides investment advice and other services to the Fund and the funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the "Funds"). On an annual basis, the Fund's Board of Directors (the "Board"), including the independent Board members (the "Independent Directors"), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in March and April 2010, including reports based on data provided by independent organizations and a comprehensive response to each item of information requested by independent legal counsel to the Independent Directors ("Independent Legal Counsel") in a letter to the investment manager, to assist the Board in making this determination. All of the materials presented in March and April 2010 were first supplied in draft form to designated representatives of the Independent Directors, i.e., Independent Legal Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials were revised to reflect comments provided by these Board representatives. In addition, throughout the year, the Board (or its committees) reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. The Board accords particular weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement. At the April 6-8, 2010 in-person Board meeting, Independent Legal Counsel reviewed with the Independent Directors, including in an executive session without management, various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Directors, approved renewal of the IMS Agreement. Nature, Extent and Quality of Services Provided by Columbia Management: The Board analyzed various reports and presentations it had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Board specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the continued investment in, and resources dedicated to, the Fund's operations, most notably, management's announcement of the massive -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 39 APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT (continued) --------------------------------------------------------- investment made in the acquisition of the long-term asset management business of Columbia Management Group, LLC (the "Columbia Transaction") and the completed integration of J. & W. Seligman & Co. Incorporated, acquisitions which should continue to enhance investment capabilities and provide access to a greater depth of experienced portfolio managers in key categories. The Board noted, in particular, that upon the close of the Columbia Transaction, the investment manager will have grown to 10 investment offices (compared to 6 in 2009). In addition, the Board reviewed information concerning the investment manager's new Chief Investment Officer upon the close of the Columbia Transaction, including the application of his particular investment philosophy, which is intended to enhance the risk and portfolio management oversight of the Funds. Moreover, in connection with the Board's evaluation of the overall package of services provided by Columbia Management, the Board considered the quality of the administrative and stockholder services provided by Columbia Management's affiliates to the Fund. The Board also reviewed the financial condition of Columbia Management and its affiliates, and each entity's ability to carry out its responsibilities. Further, the Board considered Columbia Management's ability to retain key personnel in certain targeted areas and its expectations in this regard. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board concluded that the services being performed under the IMS Agreement were of a reasonably high quality. Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that Columbia Management and its affiliates were in a position to continue to provide a high quality and level of services to the Fund. Investment Performance: For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund based on net asset value, market price and the trading price of its common stock compared to net asset value. In this regard, the Board considered detailed reports containing data prepared by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund's investment performance was appropriate in light of the particular management style. Further, the Board noted measures taken -------------------------------------------------------------------------------- 40 TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT -------------------------------------------------------------------------------- to address the Fund's performance, including the anticipated change in portfolio managers for the Fund. In this regard, the Board reviewed a detailed report illustrating the performance and track record of the new portfolio manager expected to assume responsibilities for the Fund upon the close of the Columbia Transaction. Comparative Fees, Costs of Services Provided and the Profits Realized By Columbia Management and its Affiliates from their Relationships with the Fund: The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (prepared by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its peer group, as well as data showing the Fund's contribution to Columbia Management's profitability. They also reviewed information in the report showing the fees charged by Columbia Management to other client accounts (with similar investment strategies to those of the Fund). The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the complex of Funds, while assuring that the overall fees for each Fund (with few defined exceptions) are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of each Fund, with few exceptions, is at or below the median expense ratio of funds in the same comparison group). The Board also reviewed information they received with respect to the Fund indicating that although its fee structure falls outside of the pricing philosophy, its expense ratio is lower than the median ratio for a peer group of open-end funds in a comparable asset class. Based on its review, the Board concluded that the Fund's management fee, which was reduced in 2009, was fair and reasonable in light of the extent and quality of services that the Fund receives. The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to Columbia Management and Ameriprise Financial from managing and operating the Fund, including data showing comparative profitability over the past two years. In this regard, the Board observed slightly reduced profitability in 2009 as compared with 2008. The Board also considered the services acquired by the investment manager through the use of commission dollars paid by the Fund on portfolio transactions. The Board noted that the fees paid by the Fund should permit the investment -------------------------------------------------------------------------------- TRI-CONTINENTAL CORPORATION -- 2010 SEMIANNUAL REPORT 41 APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT (continued) --------------------------------------------------------- manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable. Economies of Scale to be Realized: The Board noted that the management fee schedule for the Fund does not contain breakpoints that reduce the fee rate on assets above specified levels. However, due to the Fund's closed-end structure, the Board did not view the potential for realization of economies of scale as the Fund's assets grow to be a material factor in their deliberations. Based on the foregoing, the Board, including all of the Independent Directors, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 8, 2010, the Board, including all of the Independent Directors, approved the renewal of the IMS Agreement for an additional annual period.
