LETTER TO STOCKHOLDERS

January 21, 2005

Dear Fellow Stockholders:

      It has been an exciting and challenging first few months. We are pleased with both our progress in investing your capital and our performance to date. As of December 31, 2004, we had invested approximately $628.2 million in securities of MLPs and Other Midstream Companies, which is slightly ahead of the pace anticipated at the time of our initial public offering (“IPO”). As of that date, our portfolio consisted of $350.2 million in publicly traded securities and $278.0 million in “private” securities, representing four separate “private transactions”. Our net asset value (“NAV”) as of December 31, 2004 was up 2.3% to $24.25 per share, compared to $23.70 per share immediately following our IPO.

      One of the most difficult initial challenges for Kayne Anderson MLP Investment Company (the “Company”) has been to strike a balance between two equally important, but often competing goals. First, we want to fully invest our IPO proceeds as quickly as possible in order to fully benefit from the investment performance of the MLP asset class. At the same time, we would like to maximize the return potential of every investment we make, which often requires us to be patient and wait for opportunities that can be especially attractive. For example, we believe we can achieve attractive returns when we provide financing necessary to complete an accretive acquisition. While we have been presented with many investment opportunities, we have been selective among these in order to keep adequate “dry powder” for future opportunities. In light of the size of our Company, as well as the MLP valuation levels at the end of September 2004 when we began to invest your capital, we have worked hard to balance these competing objectives and are pleased that we have been able to achieve our initial ramp-up investment objectives in a manner consistent with our business strategy.

Market Overview

      The MLP sector during calendar 2004 has once again exhibited strong performance. For that period, a market-weighted composite of 34 MLPs (the “MLP Composite”) generated a total return of approximately 16.0% (total return is defined as unit price appreciation plus distributions). Coal MLPs (which represent only 5% of total MLP equity capitalization and are the most sensitive to commodity prices) were the strongest performing sub-sector, generating total returns of approximately 82.9%. These returns were the result of a substantial increase in coal prices, which caused both cash flows to increase and yields to decline. At calendar year-end, the three Coal MLPs had an average yield of 4.1%. The Pipeline MLP sub-sector also had a strong performance, with total returns of 14.3%. This strong performance was principally driven by increasing distributions, which rose 9.1% on average from the fourth quarter of 2003 to the fourth quarter of 2004. Average yields for this sub-sector also declined, from 6.5% to 6.2% over the calendar year. The Propane MLP sub-sector generated total returns of (2.6)% during 2004. This performance was largely due to the financial difficulties experienced by Star Gas Partners, which was forced to suspend its distribution. The other four Propane MLPs (excluding Star Gas Partners) generated total returns of 9.3% during calendar 2004. There were several successful energy MLP IPOs completed during calendar 2004, including Copano Energy, Holly Energy Partners, K-Sea Transportation Partners and U.S. Shipping Partners. These IPOs ended the year at prices that averaged 42% above their IPO prices.

      The monthly performance of the MLP Composite is shown in the table below. As you can see, the performance of MLPs was especially strong in the second half of 2004. There was a substantial downturn in April, when interest rates moved higher. From May through December, the MLP Composite generated a total return of 23.5%.

2005 Outlook

      We expect a number of factors to impact the performance of MLPs in 2005. We believe that significant investment challenges exist, while opportunities remain excellent. Just as performance among different sub-sectors of the MLP universe (coal, pipelines and propane) varied in 2004, individual performance within these sub-sectors also varied widely. We believe this will again be the case in 2005, and as a result, stock selection will be an important key to long-term investment success. We believe that the acquisition prospects for MLPs remain quite good, with many packages of midstream assets on the market or available for sale that fit well in the portfolios of many MLPs. We expect that acquisitions will continue to be accretive, with lower financing costs helping to offset higher acquisition multiples.

      The Wall Street consensus expectation is that interest rates will trend higher over the course of 2005. In a rising interest rate environment, we believe that stock selection will be critical in identifying those MLPs that will be able to increase distributions to offset higher interest rates, and where relative valuations will change as the prospects of individual MLPs improve or are reduced. We are spending much of our time analyzing the entire universe of MLPs and meeting with management teams to allow us to anticipate changes in trends and performance.

      MLP valuations, as measured by the spread between MLP yields and 10-year treasury rates, are higher (spreads lower) than the five-year average. We believe this is because of two factors. First, growth prospects for MLPs today are generally thought to be greater than they were five years ago, and we agree that this is indeed the situation. Second, with the passage of the recent legislation that facilitates the ownership of MLPs by mutual funds, and the raising of capital by other MLP-focused funds, there is much greater investor demand for MLPs than historically. We believe that MLPs, as a group, continue to offer above-average appeal with lower than average market risk. Current yield plus expected growth appears to well exceed the 8% to 9% long-term total return expected by many market strategists for the stock market. Equally important, most MLPs provide stable and predictable cash flow from “hard assets” and, by most measures of risk, provide lower risk than stocks. We remain confident that the long-term investment case for MLPs is very strong, and that our strategy of acquiring a balance of public and private securities will be successful in generating superior returns for our stockholders.

Fiscal 2004 Operating Highlights

      As of November 30, 2004, we had invested $380.0 million in MLPs and Other Midstream Companies. Approximately 83.5% of this was invested in MLP equities. In addition, we had invested 16.5% in MLP debt securities. Proceeds from our IPO that were not yet invested in portfolio companies were invested in short-term repurchase agreements.

      During the period from September 28, 2004 through November 30, 2004, we generated investment income of $2.6 million, consisting of interest income, dividends and MLP distributions. This figure does not include additional MLP distributions of $1.7 million that were treated as a return of capital. After expenses and income taxes, our net investment income for the period was $645,381. We also generated net realized and unrealized gains on investments of $10.2 million before tax and $6.1 million after tax during the period. In total, we recognized $4.5 million of taxes, of which $3.8 million was deferred.

      As a result, our net assets increased by $6.8 million during the period. On a per share basis, our NAV increased from $23.70 immediately following the IPO to $23.91 at the end of our fiscal year.

      The Company paid its first dividend of $0.25 per share to stockholders on January 14, 2005. This dividend represents an annualized yield of 6% on the IPO price of $25 per share. We expect a substantial portion of the dividends paid in 2005 to be treated as return of capital for stockholders’ income tax purposes; however, you will receive a tax notification (e.g., Form 1099) during January 2006 reflecting the final tax designation of the dividend.

      We look forward to continuing to execute on our business plan of achieving high after-tax total returns by investing in MLPs and Other Midstream Companies. We will communicate with you regularly through quarterly reports, conference calls, proxy statements, and press releases. We invite you to visit our website at www.kaynemlp.com for the latest updates.

Sincerely,

Kevin S. McCarthy

Chairman of the Board of Directors,

President and Chief Executive Officer

MANAGEMENT DISCUSSION

FOR THE PERIOD SEPTEMBER 28, 2004 THROUGH NOVEMBER 30, 2004

      This discussion contains forward looking statements and good faith estimates. The reader is referred to the disclosure on such matters at the beginning of this annual report.

      Kayne Anderson MLP Investment Company (the “Company”) began operations on September 28, 2004, following an initial public offering (“IPO”) of 30.0 million shares at $25.00 per share. On October 24, and November 14, the Company sold an additional 3.16 million shares in connection with the exercise of the underwriters’ over-allotment option. Total net proceeds to the Company, after underwriting discounts and expenses, were $786.0 million. By the end of the first fiscal period on November 30, 2004, the Company had investments in MLPs and other Midstream Energy Companies valued at $380.0 million. These investments included two private transactions valued at a total of $92.7 million. Proceeds not yet invested in portfolio companies were invested in fully-collateralized repurchase agreements.

      Subsequent to the end of the first fiscal period, the Company continued to purchase the securities of MLP and Other Midstream Companies in the public market, and it closed two additional private transactions during December. At the end of calendar 2004, the Company had invested in public equity and debt securities valued at $350.2 million and had invested in private transactions valued at $278.0 million. The total value at year-end of our long-term investments was $628.2 million. This is slightly ahead of the pace anticipated at the time of the IPO.

      During the period from September 28, 2004 to November 30, 2004, the Company earned $2.61 million in investment income. This consisted of $1.71 million of interest on repurchase agreements, $0.36 million of interest on fixed income investments, and $0.54 million in dividends and distributions from MLPs. The amount of dividends and distributions from MLPs were net of $1.67 million of distributions which were treated as return of capital. Expenses for the period were $1.53 million, which was in line with our initial budget. The advisory fee was accrued at 0.75% or the bottom fulcrum level based on the performance of the Company relative to the Standard & Poor’s 400 Utilities Index.

      Total realized and unrealized gains on investments (before taxes) were $10.21 million for the initial fiscal period. Pre-tax income, which included realized and unrealized gains and investment income, net of expenses, was $11.29 million. Accrued federal and state taxes at an estimated blended rate of 40% were $4.52 million. Net increase in net assets resulting from operations was $6.78 million or about 21¢ per share.

      Our beginning net asset value (“NAV”), after deducting underwriting costs and expenses, was $23.70. At the end of the initial fiscal period, the NAV was $23.91. The closing price of the stock on the New York Stock Exchange ranged between $25.69 and $24.87 during the initial fiscal period. The stock closed at $24.90 on November 30, 2004.

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS

November 30, 2004

1.     Organization

      Kayne Anderson MLP Investment Company (the “Company”) was organized as a Maryland corporation on June 4, 2004, and is a non-diversified, closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Company’s investment objective is to obtain a high after-tax total return by investing at least 85% of its net assets plus any borrowings (“total assets”) in energy-related master limited partnerships and their affiliates (collectively, “MLPs”), and in other companies that, as their principal business, operate assets used in the gathering, transporting, processing, storing, refining, distributing, mining or marketing of natural gas, natural gas liquids (including propane), crude oil, refined petroleum products or coal (collectively with MLPs, “Midstream Energy Companies”). The Company commenced operations on September 28, 2004. The Company’s shares of common stock are listed on the New York Stock Exchange, Inc. (“NYSE”) under the symbol “KYN”.

2.     Significant Accounting Policies

      A.     Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates.

      B.     Calculation of Net Asset Value — The Company determines its net asset value as of the close of regular session trading on the NYSE (normally 4:00 p.m. Eastern time) no less frequently than the last business day of each month, and makes its net asset value available for publication monthly. Net asset value is computed by dividing the value of the Company’s assets (including accrued interest and dividends), less all of its liabilities (including accrued expenses, dividends payable, current and deferred and other accrued income taxes, and any borrowings) and the liquidation value of any outstanding preferred stock, by the total number of common shares outstanding.

      C.     Investment Valuation — Readily marketable portfolio securities listed on any exchange other than the NASDAQ Stock Market, Inc. (“NASDAQ”) are valued, except as indicated below, at the last sale price on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the most recent bid and asked prices on such day, except for short sales and call options written, for which the last quoted asked price is used. Securities admitted to trade on the NASDAQ are valued at the NASDAQ official closing price. Portfolio securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

      Equity securities traded in the over-the-counter market, but excluding securities admitted to trading on the NASDAQ, are valued at the closing bid prices. Fixed income securities with a remaining maturity of 60 days or more are valued by the Company using a pricing service. Fixed income securities maturing within 60 days will be valued on an amortized cost basis.

      The Company holds securities that are privately issued or otherwise restricted. For these securities, as well as any other portfolio security held by the Company for which reliable market quotations are not readily available, valuations are determined in a manner that most fairly reflects fair value of the security on the

14

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

valuation date. Unless otherwise determined by the Board of Directors, the following valuation process is used for such securities:

•  Investment Team Valuation. The applicable investments are initially valued by Kayne Anderson Capital Advisors, L.P.’s (“Kayne Anderson” or the “Adviser”) investment professionals responsible for the portfolio investments;

•  Investment Team Valuation Documentation. Preliminary valuation conclusions are documented and discussed with senior management of Kayne Anderson;

•  Valuation Committee. The Valuation Committee, a committee of the Company’s Board of Directors, meets on an as-needed basis when valuations are not readily determinable. The Valuation Committee’s valuations stands for intervening periods of time unless the Valuation Committee meets again at the request of Kayne Anderson, the Board of Directors, or the Committee itself. All valuation determinations of the Valuation Committee are subject to ratification by the Board at its next regular meeting.

•  Valuation Firm. No less than quarterly, a third-party valuation firm engaged by the Board of Directors reviews the valuation methodologies and calculations employed for these securities.

•  Board of Directors Determination. The Board of Directors meets quarterly to consider the valuations provided by Kayne Anderson and the Valuation Committee, if applicable, and set valuations for the applicable securities. The Board of Directors considers the report provided by the third-party valuation firm in reviewing and determining in good faith the fair value of the applicable portfolio securities.

      At November 30, 2004, the Company held 11.70% of its net assets in securities valued at fair value as determined pursuant to procedures adopted by the Board of Directors, with an aggregate cost of $92,678,477 and fair value of $92,735,610. Although these securities may be resold in privately negotiated transactions, these values may differ from the values that would have been used had a ready market for these securities existed, and the differences could be material.

      Any option transaction that the Company enters into may, depending on the applicable market environment, have no value or a positive/negative value. Exchange traded options and futures contracts are valued at the closing price in the market where such contracts are principally traded.

      D.     Repurchase Agreements — The Company has agreed to purchase securities from financial institutions subject to the seller’s agreement to repurchase them at an agreed-upon time and price (“repurchase agreements”). The financial institutions with whom the Company enters into repurchase agreements are banks and broker/dealers which Kayne Anderson considers creditworthy. The seller under a repurchase agreement is required to maintain the value of the securities as collateral, subject to the agreement, at not less than the repurchase price plus accrued interest. Kayne Anderson monitors daily the mark-to-market of the value of the collateral, and, if necessary, requires the seller to maintain additional securities, so that the value of the collateral is not less than the repurchase price. Default by or bankruptcy of the seller would, however expose the Company to possible loss because of adverse market action or delays in connection with the disposition of the underlying securities.

      E.     Short Sales — A short sale is a transaction in which the Company sells securities it does not own (but has borrowed) in anticipation of a decline in the market price of the securities. To complete a short sale, the Company may arrange through a broker to borrow the securities to be delivered to the buyer. The proceeds received by the Company for the short sale are retained by the broker until the Company replaces the borrowed securities. In borrowing the securities to be delivered to the buyer, the Company becomes obligated to replace the securities borrowed at their market price at the time of replacement, whatever the price may be.

      All short sales are fully collateralized. The Company maintains assets consisting of cash or liquid securities equal in amount to the liability created by the short sale. These assets are adjusted daily to reflect

15

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

changes in the value of the securities sold short. The Company is liable for any dividends or distributions paid on securities sold short.

      The Company may also sell short “against the box” (i.e., the Company enters into a short sale as described above while holding an offsetting long position in the security which it sold short). If the Company enters into a short sale “against the box,” the Company segregates an equivalent amount of securities owned as collateral while the short sale is outstanding.

      The Company had no open short sales at November 30, 2004.

      F.     Option Writing — When the Company writes an option, an amount equal to the premium received by the Company is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Company on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Company has realized a gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Company. The Company, as the writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option.

      G.     Security Transactions and Investment Income — Security transactions are accounted for on the date the securities are purchased or sold (trade date). Realized gains and losses are reported on an identified cost basis. Dividend and distribution income is recorded on the ex-dividend date. Distributions received from the Company’s investments in MLPs generally are comprised of income and return of capital. For the period from September 28, 2004 (commencement of operations) through November 30, 2004, the Company recorded as return of capital the amount of $1,670,253 of dividends and distributions received from MLPs. This resulted in a reduction in the cost basis of the associated MLP investments. Net Realized Gains on Investments and Securities Sold Short and Net Change in Unrealized Appreciation of Investments and Options on the accompanying Statement of Operations includes $82,088 and $1,588,165, respectively, attributable to such dividends and distributions. The Company records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts.

      H.     Dividends to Stockholders — Dividends to stockholders are recorded on the ex-dividend date. The character of dividends made during the year may differ from their ultimate characterization for federal income tax purposes. The Company’s dividends, for book purposes, will be comprised of return of capital and ordinary income, which is based on the operating results of the Company. The Company is unable to make final determinations as to the character of the dividend until after the end of the calendar year. Since the first dividend paid to stockholders was in January 2005, the Company will inform stockholders of the final character of the dividend during January 2006.

      I.     Federal and State Income Taxation — The Company, as a corporation, is obligated to pay federal and state income tax on its taxable income. The Company invests its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Company reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Company’s tax expense or benefit is included in the Statement of Operations based on the component of income or gains/(losses) to which such expense or benefit relates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. To the extent the Company has a net deferred tax

16

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

asset, a valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset is not realized. Future realization of deferred income tax assets ultimately depends on the existence of sufficient taxable income of the appropriate character in either the carryback or carryforward period under the tax law.

      The Company may rely to some extent on information provided by the MLPs, which may not necessarily be timely, to estimate taxable income allocable to the MLP units held in the portfolio and to estimate the associated deferred tax liability. Such estimates are made in good faith and reviewed in accordance with the valuation process approved by the Board of Directors. From time to time the Company modifies its estimates or assumptions regarding the deferred tax liability as new information becomes available. To the extent such estimates or assumptions are modified, the net asset value may fluctuate.

      J.     Organization Expenses and Offering Costs — The Company is responsible for paying all organization expenses, which were expensed when the shares were issued. Such costs approximated $150,000. Offering costs related to the issuance of common stock were charged to additional paid-in capital when the shares were issued. Such costs approximated $1,635,000.

      K.     Indemnifications — Under the Company’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Company. In addition, in the normal course of business, the Company enters into contracts that provide general indemnification to other parties. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred, and may not occur. However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

3. Concentration of Risk

      The Company’s investment objective is to seek a high level of total return with an emphasis on current dividends paid to its shareholders. Under normal circumstances, the Company intends to invest at least 85% of its total assets in securities of MLPs and other Midstream Energy Companies, and to invest at least 80% of its total assets in MLPs, which are subject to certain risks, such as supply and demand risk, depletion and exploration risk, commodity pricing risk, acquisition risk, and the risk associated with the hazards inherent in midstream energy industry activities. A substantial portion of the cash flow received by the Company will be derived from the investment in equity securities of MLPs. The amount of cash that an MLP has available for distributions and the tax character of such distributions are dependent upon the amount of cash generated by the MLP’s operations. The Company may invest up to 15% of its total assets in any single issuer and a decline in value of the securities of such an issuer could significantly impact the net asset value of the Company. The Company may invest up to 20% of its total assets in debt securities, which may include below investment grade securities. The Company may, for defensive purposes, temporarily invest all or a significant portion of its assets in investment grade securities, short-term debt securities and cash or cash equivalents. To the extent the Company uses this strategy, it may not achieve its investment objectives.

4. Agreements and Affiliations

      The Company has entered into an Investment Management Agreement with Kayne Anderson under which the Adviser, subject to the overall supervision of the Company’s Board of Directors, manages the day-to-day operations of, and provide investment advisory services to, the Company. For providing these services, the Adviser receives a management fee from the Company.

      Pursuant to the Investment Management Agreement the Company has agreed to pay the Adviser a basic management fee at an annual rate of 1.75% of the Company’s average total assets, adjusted upward or downward (by up to 1.00% of the Company’s average total assets, as defined), depending on to what extent, if

17

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

any, the Company’s investment performance for the relevant performance period exceeds or trails the Company’s “Benchmark” over the same period. The Company’s Benchmark is the total return (capital appreciation and reinvested dividends) of the Standard & Poor’s 400 Utilities Index plus 600 basis points (6.00%). Each 0.01% of difference of the Company’s performance compared to the performance of the Benchmark is multiplied by a performance fee adjustment of 0.002%, up to a maximum adjustment of 1.00% (as an annual rate). The Company calculates the total management fee based on the average total assets for the prior 12 months. For the period beginning with the commencement of the Company’s operations through the end of the Company’s first 12 months of operations (the “Initial Period”), on a quarterly fiscal basis the Company pays the Adviser a minimum management fee calculated at an annual rate of 0.75%. After this Initial Period, the basic management fee and the performance fee adjustment will be calculated and paid quarterly beginning with the quarter ending November 30, 2005, using a rolling 12-month performance period. Management fees in excess of those paid will be accrued monthly.

      The performance record for the Benchmark is based on the change in value of the Benchmark during the relevant performance period. During the Company’s first fiscal year, for purposes of calculating the performance fee adjustment, the Company’s initial net asset value is calculated net of the underwriter discount. At November 30, 2004, the Company has recorded accrued management fees at the annual rate of 0.75% based on the Company’s investment performance for the period September 28, 2004 through November 30, 2004.

      For purposes of calculating the management fee, the Company’s total assets are equal to the Company’s average monthly gross asset value (which includes assets attributable to or proceeds from the Company’s use of preferred stock, commercial paper or notes issuances and other borrowings), minus the sum of the Company’s accrued and unpaid dividends on any outstanding common stock and accrued and unpaid dividends on any outstanding preferred stock and accrued liabilities (other than liabilities associated with borrowing or leverage by the Company and any accrued taxes). Liabilities associated with borrowing or leverage by the Company include the principal amount of any borrowings, commercial paper or notes issued by the Company, the liquidation preference of any outstanding preferred stock, and other liabilities from other forms of borrowing or leverage such as short positions and put or call options held or written by the Company.

      For the period September 28, 2004 through November 30, 2004, KA Associates, an affiliate of the Adviser, earned approximately $5,057 in brokerage commissions from portfolio transactions executed on behalf of the Company.

5.     Income Taxes

      Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax purposes. Components of the Company’s deferred tax assets and liabilities as of November 30, 2004 are as follows:

Deferred tax assets:
	Organization costs	$	(57,000	)
Deferred tax liabilities:
	Unrealized gains on investment securities		3,176,229
	Distributions received from MLPs		635,292
Total net deferred tax liability		$	3,754,521

      The components of income tax expense include $3,285,206 and $469,315 for deferred federal income taxes and state income taxes (net of the federal tax benefit), respectively.

18

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

      Total income taxes have been computed by applying the Federal statutory income tax rate plus a blended state income tax rate totaling 40% to net investment income and realized and unrealized gains on investments before taxes.

      At November 30, 2004, the cost basis of investments for Federal income tax purposes was $794,507,268. At November 30, 2004, gross unrealized appreciation and depreciation of investments for Federal income tax purposes were as follows:

Gross unrealized appreciation	$	11,271,707
Gross unrealized depreciation		(1,742,904	)
Net unrealized appreciation	$	9,528,803

6.     Restricted Securities

      Certain of the Company’s investments are restricted as to resale and are valued as determined in accordance with procedures established by the Board of Directors and more fully described in Note 2. The table below shows the number of units/shares held, the acquisition dates, aggregate costs, fair value as of November 30, 2004, value per unit/shares of such securities and percent of net assets which the securities comprise.

      If you decide to participate in the Plan, the number of shares of common stock you will receive will be determined as follows:

      (1) If our common stock is trading at or above net asset value at the time of valuation, we will issue new shares at a price equal to the greater of (i) our common stock’s net asset value on that date or (ii) 95% of the market price of our common stock on that date.

      (2) If our common stock is trading below net asset value at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase common stock in the open market, on the NYSE or elsewhere, for the participants’ accounts. It is possible that the market price for our common stock may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in common stock issued by us. The Plan Agent will use all dividends and distributions received in cash to purchase common stock in the open market within 30 days of the valuation date except where temporary curtailment or suspension of purchases is necessary to comply with federal securities laws. Interest will not be paid on any uninvested cash payments.

      You may withdraw from the Plan at any time by giving written notice to the Plan Agent, or by telephone in accordance with such reasonable requirements as we and the Plan Agent may agree upon. If you withdraw or the Plan is terminated, you will receive a certificate for each whole share in your account under the Plan and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus a $15.00 transaction fee and a brokerage commission.

      The Plan Agent maintains all common stockholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common stock in your account will be held by the Plan Agent in non-certificated form. The Plan Agent will forward to each participant any proxy solicitation material and will vote any shares so held only in accordance with proxies returned to us. Any proxy you receive will include all common stock you have received under the Plan.

      There is no brokerage charge for reinvestment of your dividends or distributions in common stock. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

      Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions.

      If you hold your common stock with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above. Consult your financial advisor for more information.

      There is no direct service charge to participants in the Plan; however, we reserve the right to amend or terminate the Plan if in the judgment of the Board of Directors the change is warranted. We also reserve the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained from American Stock Transfer & Trust Company at 59 Maiden Lane, New York, New York 10038. (888) 888-0317. www.amstock.com.
