ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we have filed with the Securities and Exchange Commission, or the SEC, using the "shelf" registration process. Under the shelf registration process, we may offer, from time to time, up to $1,500,000,000 of our common stock, preferred stock, debt securities or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities on the terms to be determined at the time of the offering. The securities may be offered at prices and on terms described in one or more supplements to this prospectus. This prospectus provides you with a general description of the securities that we may offer. Each time we use this prospectus to offer securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. Please carefully read this prospectus and any prospectus supplement together with any exhibits and the additional information described under the headings "Available Information" and "Risk Factors" before you make an investment decision.

PROSPECTUS SUMMARY

This summary highlights some of the information in this prospectus. It is not complete and may not contain all of the information that you may want to consider. You should read carefully the more detailed information set forth under "Risk Factors" and the other information included in this prospectus. In this prospectus and any accompanying prospectus supplement, except where the context suggests otherwise, the terms "we", "us", "our" and "Apollo Investment" refer to Apollo Investment Corporation; "Apollo Investment Management", "AIM" or "investment adviser" refers to Apollo Investment Management, L.P.; "Apollo Administration" or "AIA" refers to Apollo Investment Administration, LLC; and "Apollo" refers to the affiliated companies of Apollo Investment Management, L.P.

Apollo Investment

Apollo Investment Corporation, a Maryland corporation organized on February 2, 2004, is a closed-end, non-diversified management investment company that has elected to be treated as a BDC under the 1940 Act. In addition, for tax purposes we have elected to be treated as a regulated investment company, or RIC, under the Internal Revenue Code of 1986, as amended (the "Code").

Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in middle-market companies in the form of mezzanine and senior secured loans, as well as by making equity investments. From time to time, we may also invest in the securities of public companies as well as public companies whose securities are thinly traded.

Our portfolio is comprised primarily of investments in long-term subordinated debt, referred to as mezzanine debt, and senior secured loans of private middle-market companies, and from time to time includes equity interests such as common stock, preferred stock, warrants or options. In this prospectus, we use the term "middle-market" to refer to companies with annual revenues between $50 million and $2 billion. While our primary focus is to generate both current income and capital appreciation through investments in loans and other debt securities, both senior and subordinated, and private equity, we may invest a portion of the portfolio in opportunistic investments, such as foreign securities.

AIM and its affiliates manage other funds that may have investment mandates that are similar, in whole or in part, with ours. AIM and its affiliates may determine that an investment is appropriate both for us and for one or more of those other funds. In such event, depending on the availability of such investment and other appropriate factors, AIM may determine that we should invest on a side-by-side basis with one or more other funds. We may make all such investments subject to compliance with applicable regulations and interpretations, and our allocation procedures. In certain circumstances negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance that any such order will be obtained.

During our fiscal year ended March 31, 2008, we invested $1.8 billion across 27 new and numerous existing portfolio companies. This compares to investing $1.4 billion in 24 new and several existing portfolio companies for the previous fiscal year ended March 31, 2007. Investments sold or prepaid during the fiscal year ended March 31, 2008 totaled $714 million versus $845 million for the fiscal year ended March 31, 2007. Total invested capital since our initial public offering in April 2004 through March 31, 2008 exceeds $5.2 billion. The weighted average yields on our senior secured loan portfolio, subordinated debt portfolio and total debt portfolio at our current cost basis were 10.0%, 12.8% and 12.0%, respectively, at March 31, 2008. At March 31, 2007, the yields were 12.3%, 13.5%, and 13.1%, respectively.

At March 31, 2008, our net portfolio consisted of 71 portfolio companies and was invested 22% in senior secured loans, 57% in subordinated debt, 6% in preferred equity and 15% in common equity and warrants versus 57 portfolio companies invested 26% in senior secured loans, 61% in subordinated debt, 4% in preferred equity and 9% in common equity and warrants at March 31, 2007.

About Apollo

Founded in 1990, Apollo is a leading global alternative asset manager with a proven track record of successful private equity, distressed debt and mezzanine investing. Apollo raises, invests and manages private equity and capital markets funds on behalf of some of the world's most prominent pension and endowment funds as well as other institutional and individual investors.

Apollo's investment approach is value-oriented, focusing on industries in which it has considerable knowledge, and emphasizing downside protection and the preservation of capital. Apollo has successfully applied its investment philosophy in flexible and creative ways over its 18-year history, allowing it consistently to find attractive investment opportunities, deploy capital up and down the balance sheet of industry leading, or "franchise," businesses and create value throughout economic cycles.

Apollo's active private equity investment funds focus on making either control-oriented equity investments or distressed debt investments, either for control or non-control positions. In contrast, we seek to capitalize primarily on the significant investment opportunities emerging in the mezzanine segment of the lending market primarily for middle-market companies, which we believe offers the potential for attractive risk-adjusted returns.

About Apollo Investment Management

AIM, our investment adviser, is led by a dedicated and growing team of investment professionals and is further supported by Apollo's team of 175 professionals as of March 31, 2008. AIM's investment committee currently consists of John J. Hannan, the Chairman of our board of directors, our Chief Executive Officer and Chairman of AIM's Investment Committee; James C. Zelter, our President and Chief Operating Officer and a Vice President of the general partner of AIM; Patrick J. Dalton, an Executive Vice President of Apollo Investment and a Vice President of the general partner of AIM; and José Briones, a Vice President of the general partner of AIM. The composition of the Investment Committee of AIM may change from time to time. AIM draws upon Apollo's 18-year history and benefits from the Apollo investment professionals' significant capital markets, trading and research expertise developed through investments in many core sectors in over 150 companies since inception.

About Apollo Investment Administration

In addition to furnishing us with office facilities, equipment, and clerical, bookkeeping and record keeping services, AIA also oversees our financial records as well as the preparation of our reports to stockholders and reports filed with the SEC. AIA oversees the determination and publication of our net asset value, oversees the preparation and filing of our tax returns, and generally monitors the payment of our expenses and the performance of administrative and professional services rendered to us by others. Furthermore, AIA provides on our behalf managerial assistance to those portfolio companies to which we are required to provide such assistance.

Operating and Regulatory Structure

Our investment activities are managed by AIM and supervised by our board of directors, a majority of whom are independent of Apollo and its affiliates. AIM is an investment adviser that is registered under the Investment Advisers Act of 1940, or the Advisers Act. Under our investment advisory and management agreement, we pay AIM an annual base management fee based on our gross assets as well as an incentive fee based on our performance. See "Management—Investment Advisory and Management Agreement."

As a BDC, we are required to comply with certain regulatory requirements. Also, while we are permitted to finance investments using debt, our ability to use debt is limited in certain significant respects. See "Regulation." We have elected to be treated for federal income tax purposes as a RIC under Subchapter M of the Code. For more information, see "Material U.S. Federal Income Tax Considerations."

Determination of Net Asset Value

The net asset value per share of our outstanding shares of common stock is determined quarterly by dividing the value of our total assets minus our liabilities by the total number of our shares outstanding.

In calculating the value of our total assets, we value investments for which market quotations are readily available at such market quotations if they are deemed to represent fair value. Market quotations may be deemed not to represent fair value in certain circumstances where AIM believes that facts and circumstances applicable to an issuer, a seller or purchaser or the market for a particular security causes current market quotes to not reflect the fair value of the security. Examples of these events could include cases in which material events are announced after the close of the market on which a security is primarily traded, when a security trades infrequently causing a quoted purchase or sale price to become stale or in the event of a "fire sale" by a distressed seller. Debt and equity securities that are not publicly traded or whose market price is not readily available or whose market quotations are not deemed to represent fair value are valued at fair value as determined in good faith by, or under the direction of, our board of directors pursuant to a valuation policy and a consistently applied valuation process utilizing the input of our investment adviser, independent valuation firms, and the audit committee. Because there is no readily available market value for a significant portion of the investments in our portfolio, we value these portfolio investments at fair value.

Due to the inherent uncertainty of determining the fair value of our investments, the value of our investments may differ significantly from the values that would have been used had a readily available market existed for such investments, and the differences could be material. Determination of fair values involves subjective judgments and estimates not susceptible to substantiation by auditing procedures. Accordingly, under current auditing standards, the notes to our financial statements refer to the uncertainty with respect to the possible effect of such valuations, and any change in such valuations, on our financial statements. For more information, see "Determination of Net Asset Value."

Use of Proceeds

We intend to use the net proceeds from the sale of our securities pursuant to this prospectus for general corporate purposes, which includes investing in portfolio companies in accordance with our investment objective and strategies and repaying indebtedness incurred under our senior credit facility.

We anticipate that substantially all of the net proceeds of an offering of securities pursuant to this prospectus will be used for the above purposes within two years, depending on the availability of appropriate investment opportunities consistent with our investment objective and market conditions. Our portfolio currently consists primarily of investments in long-term subordinated debt, referred to as mezzanine debt, and senior secured loans of private middle-market companies, and from time to time includes equity interests such as common stock, preferred stock, warrants or options. Pending such investments, we will use the net proceeds of an offering to invest in cash equivalents, U.S. government securities and other high-quality debt investments that mature in one year or less from the date of investment, to reduce then-outstanding obligations under our credit facility or for other general corporate purposes. The supplement to this prospectus relating to an offering will more fully identify the use of the proceeds from such offering. For more information, see "Use of Proceeds."

Dividends on Common Stock

We intend to continue to distribute quarterly dividends to our common stockholders. Our quarterly dividends, if any, will be determined by our board of directors. For more information, see "Dividends."

Dividends on Preferred Stock

We may issue preferred stock from time to time, although we have no immediate intention to do so. If we issue shares of preferred stock, holders of such preferred stock will be entitled to receive cash dividends at an annual rate that will be fixed or will vary for the successive dividend periods for each series. In general, the dividend periods for fixed rate preferred stock will be quarterly and for any auction rate preferred stock, or ARPS, will be weekly subject to extension. With respect to ARPS, the dividend rate will be variable and will be determined for each dividend period.

Dividend Reinvestment Plan

We have adopted an "opt-out" dividend reinvestment plan that provides for reinvestment of our dividend distributions on behalf of our stockholders, unless a stockholder elects to receive cash. As a result, if our board of

directors authorizes, and we declare, a cash dividend, then our stockholders who have not "opted out" of our dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of our common stock, rather than receiving the cash dividends. A registered stockholder must notify our transfer agent in writing in order to "opt-out" of the dividend reinvestment plan. For more information, see "Dividend Reinvestment Plan."

Plan of Distribution

We may offer, from time to time, up to $1,500,000,000 of our common stock, preferred stock, debt securities or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities, on terms to be determined at the time of the offering.

Securities may be offered at prices and on terms described in one or more supplements to this prospectus directly to one or more purchasers, through agents designated from time to time by us, or to or through underwriters or dealers. The supplement to this prospectus relating to the offering will identify any agents or underwriters involved in the sale of our securities, and will set forth any applicable purchase price, fee and commission or discount arrangement or the basis upon which such amount may be calculated. In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc. ("FINRA"), the maximum compensation to the underwriters or dealers in connection with the sale of our securities pursuant to this prospectus and the accompanying supplement to this prospectus may not exceed 8% of the aggregate offering price of the securities as set forth on the cover page of the supplement to this prospectus.

We may not sell securities pursuant to this prospectus without delivering a prospectus supplement describing the method and terms of the offering of such securities. For more information, see "Plan of Distribution."

Our Corporate Information

Our administrative and principal executive offices are located at 9 West 57th Street, New York, NY 10019. Our common stock is quoted on The Nasdaq Global Select Market under the symbol "AINV." Our Internet website address is www.apolloic.com. Information contained on our website is not incorporated by reference into this prospectus and you should not consider information contained on our website to be part of this prospectus.

FEES AND EXPENSES

The following table is intended to assist you in understanding the costs and expenses that an investor in shares of our common stock will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by "you," "us" or "Apollo Investment," or that "we" will pay fees or expenses, common stockholders will indirectly bear such fees or expenses as investors in Apollo Investment.

Stockholder transaction expenses:
Sales load (as a percentage of offering price)	— (1)
Offering expenses (as a percentage of offering price)	— (2)
Total common stockholder transaction expenses (as a percentage of offering price)	— (3)
Annual expenses (as percentage of net assets attributable to common stock) (4) :
Management fees	3.15% (5)
Incentive fees payable under investment advisory and management agreement (20% of pre-incentive fee net investment income in excess of hurdle and 20% of net realized capital gains net of gross unrealized capital losses)	1.60% (6)
Other expenses	0.54% (7)
Interest and other credit facility related expenses on borrowed funds	2.94% (8)
Total annual expenses (9)	8.23% (5),(6),(7),(8)

Example

The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. These dollar amounts are based upon the assumption that our annual operating expenses (other than performance-based incentive fees) and leverage would remain at the levels set forth in the table above.

	1 year	3 years	5 years	10 years
You would pay the following expenses on a $1,000 investment, assuming a 5% annual return	$66	$194	$318	$611

While the example assumes, as required by the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. Assuming a 5% annual return, the incentive fee under the investment advisory and management agreement would not be earned or payable and is not included in the example. This illustration assumes that we will not realize any capital gains computed net of all realized capital losses and gross unrealized capital depreciation in any of the indicated time periods. If we achieve sufficient returns on our investments, including through the realization of capital gains, to trigger an incentive fee of a material amount, our expenses, and returns to our investors, would be higher. In addition, while the example assumes reinvestment of all dividends and distributions at net asset value, participants in our dividend reinvestment plan will receive a number of shares of our common stock, determined by dividing the total dollar amount of the dividend payable to a participant by the market price per share of our common stock at the close of trading on the valuation date for the dividend. See "Dividend Reinvestment Plan" for additional information regarding our dividend reinvestment plan.

This example and the expenses in the table above should not be considered a representation of our future expenses, and actual expenses may be greater or less than those shown.

_________________________

(1)	In the event that the securities to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will disclose the applicable sales load.

(2)	The related prospectus supplement will disclose the estimated amount of offering expenses, the offering price and the offering expenses borne by us as a percentage of the offering price.

(3)	The expenses of the dividend reinvestment plan are included in "Other expenses."

(4)	"Net assets attributable to common stock" equals net assets as of March 31, 2008.

(5)

The contractual management fee is calculated at an annual rate of 2.00% of our average gross total assets. Annual expenses are based on current fiscal year estimates. For more detailed information about our computation of average total assets, please see Notes 3 and 9 of our financial statements dated March 31, 2008 included in this prospectus.

(6)

Assumes that annual incentive fees earned by our investment adviser, AIM, remain consistent with the incentive fees earned by AIM for the fiscal year ended March 31, 2008. AIM earns incentive fees consisting of two parts. The first part, which is payable quarterly in arrears, is based on our pre-incentive fee net investment income for the immediately preceding calendar quarter. Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets at the end of the immediately preceding calendar quarter, is compared to the hurdle rate of 1.75% quarterly (7% annualized). Our net investment income used to calculate this part of the incentive fee is also included in the amount of our gross assets used to calculate the 2% base management fee (see footnote 5 above). Accordingly, we pay AIM an incentive fee as follows: (1) no incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the hurdle rate; (2) 100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875% in any calendar quarter; and (3) 20% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter. These calculations are appropriately pro rated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter. You should be aware that a rise in the general level of interest rates can be expected to lead to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates would make it easier for us to meet or exceed the incentive fee hurdle rate and may result in a substantial increase of the amount of incentive fees payable to our investment adviser with respect to pre-incentive fee net investment income. The second part of the incentive fee will equal 20% of our realized capital gains for the calendar year, if any, computed net of all realized capital losses and unrealized capital depreciation (and incorporating unrealized depreciation on a gross investment-by-investment basis) and is payable in arrears at the end of each calendar year. For a more detailed discussion of the calculation of this fee, see "Management—Investment Advisory and Management Agreement."

(7)

"Other expenses" are based on estimated amounts for the current fiscal year and include our estimated overhead expenses, including payments under the administration agreement based on our estimated allocable portion of overhead and other expenses incurred by AIA in performing its obligations under the administration agreement. See "Management—Administration Agreement" in this base prospectus.

(8)

Our interest and other credit facility expenses are based on current fiscal year estimates. As of March 31, 2008, we had $61 million available and $1.639 billion in borrowings outstanding under our $1.7 billion credit facility. For more information, see "Risk Factors—Risks relating to our business and structure—We fund a portion of our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us" and "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in this base prospectus.

(9)

"Total annual expenses" as a percentage of net assets attributable to common stock are higher than the total annual expenses percentage would be for a company that is not leveraged. We borrow money to leverage our net assets and increase our total assets. The SEC requires that the "Total annual expenses" percentage be calculated as a percentage of net assets (defined as total assets less indebtedness), rather than the total assets, including assets that have been funded with borrowed monies. If the "Total annual expenses" percentage were calculated instead as a percentage of total assets, our "Total annual expenses" would be 4.59% of total assets. For a presentation and calculation of total annual expenses based on total assets, see page 24 of this base prospectus.

RISK FACTORS

Before you invest in our shares, you should be aware of various risks, including those described below. You should carefully consider these risk factors, together with all of the other information included in this prospectus, before you decide whether to make an investment in our securities. The risks set out below are not the only risks we face. If any of the following events occur, our business, financial condition and results of operations could be materially adversely affected. In such case, our net asset value and the trading price of our common stock could decline or the value of our preferred stock, debt securities or warrants may decline, and you may lose all or part of your investment.

RISKS RELATING TO OUR BUSINESS AND STRUCTURE

We can offer no assurance that we will be able to replicate our own success or the success of Apollo's private funds and our investment returns could be substantially lower than the returns achieved by those private funds.

Even though AIM is led by senior investment professionals of Apollo who apply the value-oriented philosophy and techniques used by the Apollo investment professionals in their private fund investing, our investment strategies and objective differ from those of other private funds that are or have been managed by the Apollo investment professionals. Further, investors in Apollo Investment are not acquiring an interest in other Apollo funds. Further, while Apollo Investment may consider potential co-investment participation in portfolio investments with other Apollo funds, any such investment activity is subject to a number of limitations, including applicable allocation policies and regulatory limitations on certain types of co-investment activity. Certain types of negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance that any such order will be obtained. Accordingly, we can offer no assurance that Apollo Investment will replicate Apollo's historical success, and we caution you that our investment returns could be substantially lower than the returns achieved by those private funds. Finally, we can offer no assurance that AIM will be able to continue to implement our investment objective with the same degree of success as it has in the past or that shares of our common stock will continue to trade at the current level.

We are dependent upon Apollo Investment Management's key personnel for our future success and upon their access to Apollo's investment professionals and partners.

We depend on the diligence, skill and network of business contacts of the senior management of AIM. Members of our senior management may depart at any time. For a description of the senior management team, see "Management." We also depend, to a significant extent, on AIM's access to the investment professionals and partners of Apollo and the information and deal flow generated by the Apollo investment professionals in the course of their investment and portfolio management activities. The senior management of AIM evaluates, negotiates, structures, closes and monitors our investments. Our future success depends on the continued service of the senior management team of AIM. The departure of any directors or any senior managers of AIM, or of a significant number of the investment professionals or partners of Apollo, could have a material adverse effect on our ability to achieve our investment objective. In addition, we can offer no assurance that AIM will remain our investment adviser or that we will continue to have access to Apollo's partners and investment professionals or its information and deal flow.

Our financial condition and results of operation depend on our ability to manage future growth effectively.

Our ability to achieve our investment objective depends, in part, on our ability to grow, which depends, in turn, on AIM's ability to identify, invest in and monitor companies that meet our investment criteria. Accomplishing this result on a cost-effective basis is largely a function of AIM's structuring of the investment process, its ability to provide competent, attentive and efficient services to us and our access to financing on acceptable terms. The senior management team of AIM has substantial responsibilities under the investment advisory and management agreement, as well as in connection with their roles as officers of other Apollo funds.

They may also be called upon to provide managerial assistance to our portfolio companies as principals of our administrator. These demands on their time may distract them or slow the rate of investment. In order to grow, we

and AIM need to hire, train, supervise and manage new employees. Any failure to manage our future growth effectively could have a material adverse effect on our business, financial condition and results of operations.

We operate in a highly competitive market for investment opportunities.

A number of entities compete with us to make the types of investments that we make. We compete with public and private funds, commercial and investment banks, commercial financing companies, and, to the extent they provide an alternative form of financing, private equity funds. Additionally, because competition for investment opportunities generally has increased among alternative investment vehicles, such as hedge funds, those entities have begun to invest in areas they have not traditionally invested in. As a result of these new entrants, competition for investment opportunities has intensified and we expect that trend to continue. Some of our existing and potential competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, some competitors may have a lower cost of funds and access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC. We cannot assure you that the competitive pressures we face will not have a material adverse effect on our business, financial condition and results of operations. Also, as a result of this existing and increasing competition, we may not be able to take advantage of attractive investment opportunities from time to time, and we can offer no assurance that we will be able to identify and make investments that are consistent with our investment objective.

We do not seek to compete primarily based on the interest rates we offer, and we believe that some of our competitors make loans with interest rates that are comparable to or lower than the rates we offer.

We may lose investment opportunities if we do not match our competitors' pricing, terms and structure. If we match our competitors' pricing, terms and structure, we may experience decreased net interest income and increased risk of credit loss.

Any failure on our part to maintain our status as a BDC would reduce our operating flexibility.

If we do not remain a BDC, we might be regulated as a closed-end investment company under the 1940 Act, which would subject us to substantially more regulatory restrictions under the 1940 Act and correspondingly decrease our operating flexibility.

We will be subject to corporate-level income tax if we are unable to qualify as a RIC.

To qualify as a RIC under the Code, we must meet certain source-of-income, asset diversification and annual distribution requirements. The annual distribution requirement for a RIC is satisfied if we distribute at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, to our stockholders on an annual basis. To the extent we use debt financing, we are subject to certain asset coverage ratio requirements under the 1940 Act and financial covenants under loan and credit agreements that could, under certain circumstances, restrict us from making distributions necessary to qualify as a RIC. If we are unable to obtain cash from other sources, we may fail to qualify as a RIC and, thus, may be subject to corporate-level income tax. To qualify as a RIC, we must also meet certain asset diversification requirements at the end of each calendar quarter. Failure to meet these tests may result in our having to dispose of certain investments quickly in order to prevent the loss of RIC status. Because most of our investments are in private companies, any such dispositions could be made at disadvantageous prices and may result in substantial losses. If we fail to qualify as a RIC for any reason and become subject to corporate-level income tax, the resulting corporate-level taxes could substantially reduce our net assets, the amount of income available for distribution and the amount of our distributions. Such a failure would have a material adverse effect on us and our stockholders.

We may have difficulty paying our required distributions if we recognize income before or without receiving cash representing such income.

For federal income tax purposes, we include in income certain amounts that we have not yet received in cash, such as original issue discount, which may arise if we receive warrants in connection with the making of a loan

or possibly in other circumstances, or payment-in-kind interest, which represents contractual interest added to the loan balance and due at the end of the loan term. Such original issue discount, which could be significant relative to Apollo Investment's overall investment activities, or increases in loan balances as a result of payment-in-kind arrangements are included in income before we receive any corresponding cash payments. We also may be required to include in income certain other amounts that we do not receive in cash.

That part of the incentive fee payable by us that relates to our net investment income is computed and paid on income that may include interest that has been accrued but not yet received in cash. If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible.

Since in certain cases we may recognize income before or without receiving cash representing such income, we may have difficulty meeting the tax requirement to distribute at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, to maintain our status as a RIC. Accordingly, we may have to sell some of our investments at times we would not consider advantageous, raise additional debt or equity capital or reduce new investment originations to meet these distribution requirements. See "Material U.S. Federal Income Tax Considerations—Taxation as a RIC."

Regulations governing our operation as a BDC affect our ability to, and the way in which we raise, additional capital.

We may issue debt securities or preferred stock and/or borrow money from banks or other financial institutions, which we refer to collectively as "senior securities," up to the maximum amount permitted by the 1940 Act. Under the provisions of the 1940 Act, we are permitted, as a BDC, to issue senior securities only in amounts such that our asset coverage, as defined in the 1940 Act, equals at least 200% after each issuance of senior securities. If the value of our assets declines, we may be unable to satisfy this test. If that happens, the contractual arrangements governing these securities may require us to sell a portion of our investments and, depending on the nature of our leverage, repay a portion of our indebtedness at a time when such sales may be disadvantageous.

BDCs may issue and sell common stock at a price below net asset value per share only in limited circumstances, one of which is during the one-year period after stockholder approval. Our stockholders recently approved a plan so that we may, in one or more public or private offerings of our common stock, sell or otherwise issue shares of our common stock at a price below the then current net asset value per share, subject to certain conditions discussed below. This plan will be effective for a 12-month period beginning August 2008.

We will sell shares of our common stock at a price below net asset value per share, exclusive of sales compensation, only if the following conditions are met:

the price per share received for such shares must be equal to or greater than the net asset value less a maximum of (a) 5% of net asset value and (b) any underwriting commission or discount on such sale (which net asset value will be determined in accordance with the 1940 Act as of a time within 48 hours, excluding Sundays and holidays, next preceding the time of such determination);

a majority of our independent directors who have no financial interest in the sale have approved the sale; and

a majority of our independent directors, in consultation with the underwriter or underwriters of the offering if it is to be underwritten, have determined in good faith, and as of a time immediately prior to the first solicitation by or on behalf of us of firm commitments to purchase such securities or immediately prior to the issuance of such securities, that the price at which such securities are to be sold is not less than a price that closely approximates the market value of those securities, less any underwriting commission or discount.

In addition to issuing securities to raise capital as described above, we may in the future seek to securitize our loans to generate cash for funding new investments. To securitize loans, we may create a wholly owned subsidiary and contribute a pool of loans to the subsidiary and have the subsidiary issue primarily investment grade debt securities to purchasers who we would expect to be willing to accept a substantially lower interest rate

than the loans earn. We would retain all or a portion of the equity in the securitized pool of loans. Our retained equity would be exposed to any losses on the portfolio of loans before any of the debt securities would be exposed to such losses. Accordingly, if the pool of loans experienced a low level of losses due to defaults, we would earn an incremental amount of income on our retained equity but we would be exposed, up to the amount of equity we retained, to that proportion of any losses we would have experienced if we had continued to hold the loans in our portfolio. We would not treat the debt issued by such a subsidiary as senior securities. An inability to successfully securitize our loan portfolio could limit our ability to grow our business and fully execute our business strategy, and could decrease our earnings, if any. Moreover, the successful securitization of our loan portfolio might expose us to losses because the residual loans in which we do not sell interests may tend to be those that are riskier and more apt to generate losses.

We currently use borrowed funds to make investments and are exposed to the typical risks associated with leverage.

We are exposed to increased risk of loss due to our use of debt to make investments. A decrease in the value of our investments will have a greater negative impact on the value of our common stock than if we did not use debt. Our ability to pay dividends will be restricted if our asset coverage ratio falls below at least 200% and any amounts that we use to service our indebtedness are not available for dividends to our common stockholders.

Our current and future debt securities are and may be governed by an indenture or other instrument containing covenants restricting our operating flexibility. We, and indirectly our stockholders, bear the cost of issuing and servicing such securities. Any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock.

We fund a portion of our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us.

Borrowings, also known as leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in our securities. Our lenders have fixed dollar claims on our assets that are superior to the claims of our common stockholders or any preferred stockholders. If the value of our assets increases, then leveraging would cause the net asset value to increase more sharply than it would have had we not leveraged. Conversely, if the value of our assets decreases, leveraging would cause net asset value to decline more sharply than it otherwise would have had we not leveraged. Similarly, any increase in our income in excess of consolidated interest payable on the borrowed funds would cause our net income to increase more than it would without the leverage, while any decrease in our income would cause net income to decline more sharply than it would have had we not borrowed. Such a decline could negatively affect our ability to make common stock dividend payments. Leverage is generally considered a speculative investment technique.

We may in the future determine to fund a portion of our investments with preferred stock, which would magnify the potential for gain or loss and the risks of investing in us in the same way as our borrowings.

Preferred stock, which is another form of leverage, has the same risks to our common stockholders as borrowings because the dividends on any preferred stock we issue must be cumulative. Payment of such dividends and repayment of the liquidation preference of such preferred stock must take preference over any dividends or other payments to our common stockholders, and preferred stockholders are not subject to any of our expenses or losses and are not entitled to participate in any income or appreciation in excess of their stated preference.

Changes in interest rates may affect our cost of capital and net investment income.

Because we borrow money, and may issue preferred stock to finance investments, our net investment income will depend, in part, upon the difference between the rate at which we borrow funds or pay dividends on preferred stock and the rate at which we invest these funds. As a result, we can offer no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income. In periods of rising interest rates, our cost of funds would increase except to the extent we issue fixed rate debt or preferred stock, which could reduce our net investment income. Our long-term fixed-rate investments are financed primarily with equity and long-term debt. We may use interest rate risk management techniques in an effort to limit our exposure to interest rate fluctuations. Such techniques may include various interest rate hedging activities to the extent permitted by

the 1940 Act. We have analyzed the potential impact of changes in interest rates on interest income net of interest expense. Assuming that the balance sheet were to remain constant and no actions were taken to alter the existing interest rate sensitivity, a hypothetical immediate 1% change in interest rates would have adversely affected our net income over a one-year horizon. Although management believes that this is indicative of our sensitivity to interest rate changes, it does not adjust for potential changes in credit quality, size and composition of the assets on the balance sheet and other business developments that could affect net increase in net assets resulting from operations, or net income. Accordingly, no assurances can be given that actual results would not differ materially from the potential outcome simulated by this estimate.

You should also be aware that a rise in the general level of interest rates can be expected to lead to higher interest rates we receive on many of our debt investments. Accordingly, an increase in interest rates would make it easier for us to meet or exceed the incentive fee hurdle rate and may result in a substantial increase in the amount of incentive fees payable to our investment adviser with respect to pre-incentive fee net investment income.

We need to raise additional capital to grow because we must distribute most of our income.

We may need additional capital to fund growth in our investments. We have issued equity securities and have borrowed from financial institutions. A reduction in the availability of new capital could limit our ability to grow. We must distribute at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, to our stockholders to maintain our regulated investment company status. As a result, such earnings are not available to fund investment originations. We expect to continue to borrow from financial institutions and issue additional debt and equity securities. If we fail to obtain funds from such sources or from other sources to fund our investments, it could limit our ability to grow, which may have an adverse effect on the value of our securities. In addition, as a BDC, we are generally required to maintain a ratio of at least 200% of total assets to total borrowings and preferred stock, which may restrict our ability to borrow or issue additional preferred stock in certain circumstances.

Many of our portfolio investments are recorded at fair value as determined in good faith by or under the direction of our board of directors and, as a result, there is uncertainty as to the value of our portfolio investments.

A large percentage of our portfolio investments are not publicly traded. The fair value of these investments may not be readily determinable. We value these investments quarterly at fair value as determined in good faith by or under the direction of our board of directors pursuant to a valuation policy and a consistently applied valuation process utilizing the input of our investment adviser, independent valuation firms and the audit committee. Our board of directors utilizes the services of several independent valuation firms to aid it in determining the fair value of these investments. The types of factors that may be considered in fair value pricing of these investments include the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings, the markets in which the portfolio company does business, comparison to publicly traded companies, discounted cash flow and other relevant factors. Because such valuations, and particularly valuations of private securities and private companies, are inherently uncertain, may fluctuate over short periods of time and may be based on estimates, our determinations of fair value may differ materially from the values that would have been used if a readily available market for these investments existed and may differ materially from the amounts we realize on any disposition of such investments. Our net asset value could be adversely affected if our determinations regarding the fair value of these investments were materially higher than the values that we ultimately realize upon the disposal of such investments.

The lack of liquidity in our investments may adversely affect our business.

We generally make investments in private companies. Substantially all of these securities are subject to legal and other restrictions on resale or are otherwise less liquid than publicly traded securities. The illiquidity of our investments may make it difficult for us to sell such investments if the need arises. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we have previously recorded our investments. In addition, we may face other restrictions on our ability to liquidate an investment in a portfolio company to the extent that we or an affiliated manager of Apollo has material non-public information regarding such portfolio company.

We may experience fluctuations in our periodic results.

We could experience fluctuations in our periodic operating results due to a number of factors, including the interest rates payable on the debt securities we acquire, the default rate on such securities, the level of our expenses (including the interest rates payable on our borrowings, the dividends rates on preferred stock we issue, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and general economic conditions. As a result of these factors, results for any period should not be relied upon as being indicative of performance in future periods.

There are significant potential conflicts of interest which could adversely affect our investment returns.

Our executive officers and directors, and the partners of our investment adviser, AIM, serve or may serve as officers, directors or principals of entities that operate in the same or a related line of business as we do or of investment funds managed by our affiliates. Accordingly, they may have obligations to investors in those entities, the fulfillment of which might not be in the best interests of us or our stockholders. Moreover, we note that, notwithstanding the difference in principal investment objectives between us and other Apollo funds, such other Apollo sponsored funds, including new affiliated potential pooled investment vehicles or managed accounts not yet established, have and may from time to time have overlapping investment objectives with us and, accordingly, invest in, whether principally or secondarily, asset classes similar to those targeted by us. To the extent such other investment vehicles have overlapping investment objectives, the scope of opportunities otherwise available to us may be adversely affected and/or reduced. As a result, the partners of AIM may face conflicts in their time management and commitments as well as in the allocation of investment opportunities to other Apollo funds. In addition, in the event such investment opportunities are allocated among ourselves and other investment vehicles affiliated with AIM, our desired investment portfolio may be adversely affected. Although AIM endeavors to allocate investment opportunities in a fair and equitable manner, it is possible that we may not be given the opportunity to participate in certain investments made by investment funds managed by investment managers affiliated with AIM.

There are no information barriers amongst Apollo and certain of its affiliates. If AIM were to receive material non-public information about a particular company, or have an interest in investing in a particular company, Apollo or certain of its affiliates may be prevented from investing in such company. Conversely, if Apollo or certain of its affiliates were to receive material non-public information about a particular company, or have an interest in investing in a particular company, we may be prevented in investing in such company.

AIM and its affiliates and investment managers may determine that an investment is appropriate both for us and for one or more other funds. In such event, depending on the availability of such investment and other appropriate factors, AIM may determine that we should invest on a side-by-side basis with one or more other funds. We may make all such investments subject to compliance with applicable regulations and interpretations, and our allocation procedures. In certain circumstances negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance that any such order will be obtained.

In the course of our investing activities, we pay management and incentive fees to AIM, and reimburse AIM for certain expenses it incurs. As a result, investors in our common stock invest on a "gross" basis and receive distributions on a "net" basis after expenses, resulting in, among other things, a lower rate of return than one might achieve through direct investments. As a result of this arrangement, there may be times when the management team of AIM has interests that differ from those of our common stockholders, giving rise to a conflict.

AIM receives a quarterly incentive fee based, in part, on our pre-incentive fee income, if any, for the immediately preceding calendar quarter. This incentive fee is subject to a quarterly hurdle rate before providing an incentive fee return to the investment adviser. To the extent we or AIM are able to exert influence over our portfolio companies, the quarterly pre-incentive fee may provide AIM with an incentive to induce our portfolio companies to accelerate or defer interest or other obligations owed to us from one calendar quarter to another.

We have entered into a royalty-free license agreement with Apollo, pursuant to which Apollo has agreed to grant us a non-exclusive license to use the name "Apollo." Under the license agreement, we have the right to use the "Apollo" name for so long as AIM or one of its affiliates remains our investment adviser. In addition, we rent office space from AIA, an affiliate of AIM, and pay Apollo Administration our allocable portion of overhead and other

expenses incurred by AIA in performing its obligations under the administration agreement, including our allocable portion of the cost of our Chief Financial Officer and Chief Compliance Officer and their respective staffs, which can create conflicts of interest that our board of directors must monitor.

In the past following periods of volatility in the market price of a company's securities, securities class action litigation has often been brought against that company.

If our stock price fluctuates significantly, we may be the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management's attention and resources from our business.

Changes in laws or regulations governing our operations may adversely affect our business.

We and our portfolio companies are subject to regulation by laws at the local, state and federal levels. These laws and regulations, as well as their interpretation, may be changed from time to time. Accordingly, any change in these laws or regulations could have a material adverse affect on our business.

Provisions of the Maryland General Corporation Law and of our charter and bylaws could deter takeover attempts and have an adverse impact on the price of our common stock.

The Maryland General Corporation Law, our charter and our bylaws contain provisions that may discourage, delay or make more difficult a change in control of Apollo Investment or the removal of our directors. We are subject to the Maryland Business Combination Act, subject to any applicable requirements of the 1940 Act. Our board of directors has adopted a resolution exempting from the Business Combination Act any business combination between us and any other person, subject to prior approval of such business combination by our board of directors, including approval by a majority of our disinterested directors. If the resolution exempting business combinations is repealed or our board of directors does not approve a business combination, the Business Combination Act may discourage third parties from trying to acquire control of us and increase the difficulty of consummating such an offer. Our bylaws exempt from the Maryland Control Share Acquisition Act acquisitions of our common stock by any person. If we amend our bylaws to repeal the exemption from the Control Share Acquisition Act, the Control Share Acquisition Act also may make it more difficult for a third party to obtain control of us and increase the difficulty of consummating such an offer.

We have also adopted other measures that may make it difficult for a third party to obtain control of us, including provisions of our charter classifying our board of directors in three classes serving staggered three-year terms, and provisions of our charter authorizing our board of directors to classify or reclassify shares of our stock in one or more classes or series, to cause the issuance of additional shares of our stock, and to amend our charter, without stockholder approval, to increase or decrease the number of shares of stock that we have authority to issue. These provisions, as well as other provisions of our charter and bylaws, may delay, defer or prevent a transaction or a change in control that might otherwise be in the best interests of our stockholders.

RISKS RELATED TO OUR INVESTMENTS

We may not realize gains from our equity investments.

When we invest in mezzanine or senior secured loans, we have and may continue to acquire warrants or other equity securities as well. In addition, we may invest directly in the equity securities of portfolio companies. Our goal is ultimately to dispose of such equity interests and realize gains upon our disposition of such interests. However, the equity interests we receive may not appreciate in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains from our equity interests, and any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other losses we experience.

Our ability to invest in public companies may be limited in certain circumstances.

As a BDC, we must not acquire any assets other than "qualifying assets" specified in the 1940 Act unless, at the time the acquisition is made, at least 70% of our total assets are qualifying assets (with certain limited exceptions) Subject to certain exceptions for follow-on investments and distressed companies, an investment in an

issuer that has outstanding securities listed on a national securities exchange, may be treated as qualifying assets only if such issuer has a market capitalization that is less than $250 million at the time of such investment.

Our portfolio is concentrated in a limited number of portfolio companies, which subject us to a risk of significant loss if any of these companies defaults on its obligations under any of its debt securities.

A consequence of the limited number of investments in our portfolio is that the aggregate returns we realize may be significantly adversely affected if a small number of investments perform poorly or if we need to write down the value of any one investment. Beyond our income tax diversification requirements, we do not have fixed guidelines for diversification, and our investments could be concentrated in relatively few portfolio companies.

Our investments in prospective portfolio companies may be risky, and you could lose all or part of your investment.

Investment in middle-market companies involves a number of significant risks. Middle-market companies may have limited financial resources and may be unable to meet their obligations under their debt securities that we hold, which may be accompanied by a deterioration in the value of any collateral and a reduction in the likelihood of us realizing any guarantees we may have obtained in connection with our investment. In addition, they typically have shorter operating histories, narrower product lines and smaller market shares than larger businesses, which tend to render them more vulnerable to competitors' actions and market conditions, as well as general economic downturns. Middle-market companies are more likely to depend on the management talents and efforts of a small group of persons; therefore, the death, disability, resignation or termination of one or more of these persons could have a material adverse impact on our portfolio company and, in turn, on us. Middle-market companies also generally have less predictable operating results, may from time to time be parties to litigation, may be engaged in rapidly changing businesses with products subject to a substantial risk of obsolescence, and may require substantial additional capital to support their operations, finance expansion or maintain their competitive position. In addition, our executive officers, directors and our investment adviser may, in the ordinary course of business, be named as defendants in litigation arising from our investments in the portfolio companies.

Economic recessions or downturns could impair our portfolio companies and harm our operating results.

Many of our portfolio companies may be susceptible to economic slowdowns or recessions and may be unable to repay our loans during these periods. Therefore, our non-performing assets are likely to increase and the value of our portfolio is likely to decrease during these periods. Adverse economic conditions also may decrease the value of collateral securing some of our loans and the value of our equity investments. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. These events could prevent us from increasing investments and harm our operating results.

A portfolio company's failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, termination of its loans and foreclosure on its secured assets, which could trigger cross-defaults under other agreements and jeopardize our portfolio company's ability to meet its obligations under the debt securities that we hold. We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting portfolio company. In addition, if one of our portfolio companies were to go bankrupt, even though we or one of our affiliates may have structured our interest as senior debt, depending on the facts and circumstances, including the extent to which we actually provided managerial assistance to that portfolio company, a bankruptcy court might re-characterize our debt holding and subordinate all or a portion of our claim to that of other creditors.

Our failure to make follow-on investments in our portfolio companies could impair the value of our portfolio.

Following an initial investment in a portfolio company, we may make additional investments in that portfolio company as "follow-on" investments, in order to: (1) increase or maintain in whole or in part our equity ownership percentage; (2) exercise warrants, options or convertible securities that were acquired in the original or subsequent financing or (3) attempt to preserve or enhance the value of our investment.

We may elect not to make follow-on investments or otherwise lack sufficient funds to make those investments. We have the discretion to make any follow-on investments, subject to the availability of capital resources. The failure to make follow-on investments may, in some circumstances, jeopardize the continued viability of a portfolio company and our initial investment, or may result in a missed opportunity for us to increase our participation in a successful operation. Even if we have sufficient capital to make a desired follow-on investment, we may elect not to make a follow-on investment because we may not want to increase our concentration of risk, because we prefer other opportunities, or because we are inhibited by compliance with BDC requirements or the desire to maintain our tax status.

When we do not hold controlling equity interests in our portfolio companies, we may not be in a position to exercise control over our portfolio companies or to prevent decisions by management of our portfolio companies that could decrease the value of our investments.

We do not generally take controlling equity positions in our portfolio companies. To the extent that we do not hold a controlling equity interest in a portfolio company, we are subject to the risk that a portfolio company may make business decisions with which we disagree, and the stockholders and management of a portfolio company may take risks or otherwise act in ways that are adverse to our interests. Due to the lack of liquidity for the debt and equity investments that we typically hold in our portfolio companies, we may not be able to dispose of our investments in the event we disagree with the actions of a portfolio company, and may therefore suffer a decrease in the value of our investments.

An investment strategy focused primarily on privately-held companies presents certain challenges, including the lack of available information about these companies, a dependence on the talents and efforts of only a few key portfolio company personnel and a greater vulnerability to economic downturns.

We have invested and will continue to invest primarily in privately-held companies. Generally, little public information exists about these companies, and we are required to rely on the ability of AIM's investment professionals to obtain adequate information to evaluate the potential returns from investing in these companies.

If we are unable to uncover all material information about these companies, we may not make a fully informed investment decision, and we may lose money on our investments. Also, privately-held companies frequently have less diverse product lines and smaller market presence than public company competitors, which often are larger. These factors could affect our investment returns.

Our portfolio companies may incur debt that ranks equally with, or senior to, our investments in such companies.

We have invested and intend to invest primarily in mezzanine and senior debt securities issued by our portfolio companies. The portfolio companies usually have, or may be permitted to incur, other debt that ranks equally with, or senior to, the debt securities in which we invest. By their terms, such debt instruments may provide that the holders are entitled to receive payment of interest or principal on or before the dates on which we are entitled to receive payments in respect of the debt securities in which we invest. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, holders of debt instruments ranking senior to our investment in that portfolio company would typically be entitled to receive payment in full before we receive any distribution in respect of our investment. After repaying such senior creditors, such portfolio company may not have any remaining assets to use for repaying its obligation to us. In the case of debt ranking equally with debt securities in which we invest, we would have to share on an equal basis any distributions with other creditors holding such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio company. In addition, we may not be in a position to control any portfolio company by investing in its debt securities. As a result, we are subject to the risk that a portfolio company in which we invest may make business decisions with which we disagree and the management of such company, as representatives of the holders of their common equity, may take risks or otherwise act in ways that do not serve our interests as debt investors.

Our incentive fee may induce AIM to make certain investments, including speculative investments.

The incentive fee payable by us to AIM may create an incentive for AIM to make investments on our behalf that are risky or more speculative than would be the case in the absence of such compensation arrangement.

The way in which the incentive fee payable to AIM is determined, which is calculated as a percentage of the return on invested capital, may encourage our investment adviser to use leverage to increase the return on our investments. Under certain circumstances, the use of leverage may increase the likelihood of default, which would disfavor the holders of our common stock, including investors in offerings of common stock, securities convertible into our common stock or warrants representing rights to purchase our common stock or securities convertible into our common stock pursuant to this prospectus. In addition, AIM receives the incentive fee based, in part, upon net capital gains realized on our investments. Unlike the portion of the incentive fee based on income, there is no hurdle rate applicable to the portion of the incentive fee based on net capital gains. As a result, AIM may have a tendency to invest more in investments that are likely to result in capital gains as compared to income producing securities. Such a practice could result in our investing in more speculative securities than would otherwise be the case, which could result in higher investment losses, particularly during economic downturns.

The incentive fee payable by us to AIM also may create an incentive for AIM to invest on our behalf in instruments that have a deferred interest feature. Under these investments, we would accrue the interest over the life of the investment but would not receive the cash income from the investment until the end of the term. Our net investment income used to calculate the income portion of our investment fee, however, includes accrued interest. Thus, a portion of this incentive fee would be based on income that we have not yet received in cash.

We may invest, to the extent permitted by law, in the securities and instruments of other investment companies, including private funds, and, to the extent we so invest, will bear our ratable share of any such investment company's expenses, including management and performance fees. We will also remain obligated to pay management and incentive fees to AIM with respect to the assets invested in the securities and instruments of other investment companies. With respect to each of these investments, each of our common stockholders will bear his or her share of the management and incentive fee of AIM as well as indirectly bearing the management and performance fees and other expenses of any investment companies in which we invest.

Our investments in foreign securities may involve significant risks in addition to the risks inherent in U.S. investments.

Our investment strategy contemplates that a portion of our investments may be in securities of foreign companies. Investing in foreign companies may expose us to additional risks not typically associated with investing in U.S. companies. These risks include changes in exchange control regulations, political and social instability, expropriation, imposition of foreign taxes, less liquid markets and less available information than is generally the case in the United States, higher transaction costs, less government supervision of exchanges, brokers and issuers, less developed bankruptcy laws, difficulty in enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.

Although most of our investments are denominated in U.S. dollars, our investments that are denominated in a foreign currency are subject to the risk that the value of a particular currency may change in relation to one or more other currencies. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital appreciation, and political developments. We may employ hedging techniques to minimize these risks, but we can offer no assurance that we will, in fact, hedge currency risk or, that if we do, such strategies will be effective.

If we engage in hedging transactions, we may expose ourselves to risks associated with such transactions. We may utilize instruments such as forward contracts, currency options and interest rate swaps, caps, collars and floors to seek to hedge against fluctuations in the relative values of our portfolio positions from changes in currency exchange rates and market interest rates. Hedging against a decline in the values of our portfolio positions does not eliminate the possibility of fluctuations in the values of such positions or prevent losses if the values of such positions decline. However, such hedging can establish other positions designed to gain from those same developments, thereby offsetting the decline in the value of such portfolio positions. Such hedging transaction may also limit the opportunity for gain if the values of the underlying portfolio positions should increase. Moreover, it may not be possible to hedge against an exchange rate or interest rate fluctuation that is so generally anticipated that we are not able to enter into a hedging transaction at an acceptable price.

While we may enter into transactions to seek to reduce currency exchange rate and interest rate risks, unanticipated changes in currency exchange rates or interest rates may result in poorer overall investment performance than if we had not engaged in any such hedging transactions. In addition, the degree of correlation between price movements of the instruments used in a hedging strategy and price movements in the portfolio positions being hedged may vary. Moreover, for a variety of reasons, we may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Any such imperfect correlation may prevent us from achieving the intended hedge and expose us to risk of loss. In addition, it may not be possible to hedge fully or perfectly against currency fluctuations affecting the value of securities denominated in non-U.S. currencies because the value of those securities is likely to fluctuate as a result of factors not related to currency fluctuations.

RISKS RELATED TO ISSUANCE OF OUR PREFERRED STOCK

An investment in our preferred stock should not constitute a complete investment program.

If we issue preferred stock, the net asset value and market value of our common stock may become more volatile.

We cannot assure that the issuance of preferred stock would result in a higher yield or return to the holders of the common stock. The issuance of preferred stock would likely cause the net asset value and market value of the common stock to become more volatile. If the dividend rate on the preferred stock were to approach the net rate of return on our investment portfolio, the benefit of leverage to the holders of the common stock would be reduced. If the dividend rate on the preferred stock were to exceed the net rate of return on our portfolio, the leverage would result in a lower rate of return to the holders of common stock than if we had not issued preferred stock. Any decline in the net asset value of our investments would be borne entirely by the holders of common stock. Therefore, if the market value of our portfolio were to decline, the leverage would result in a greater decrease in net asset value to the holders of common stock than if we were not leveraged through the issuance of preferred stock. This greater net asset value decrease would also tend to cause a greater decline in the market price for the common stock. We might be in danger of failing to maintain the required asset coverage of the preferred stock or of losing our ratings on the preferred stock or, in an extreme case, our current investment income might not be sufficient to meet the dividend requirements on the preferred stock. In order to counteract such an event, we might need to liquidate investments in order to fund a redemption of some or all of the preferred stock. In addition, we would pay (and the holders of common stock would bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred stock, including higher advisory fees if our total return exceeds the dividend rate on the preferred stock. Holders of preferred stock may have different interests than holders of common stock and may at times have disproportionate influence over our affairs.

Holders of any preferred stock we might issue would have the right to elect members of the board of directors and class voting rights on certain matters.

Holders of any preferred stock we might issue, voting separately as a single class, would have the right to elect two members of the board of directors at all times and in the event dividends become two full years in arrears would have the right to elect a majority of the directors until such arrearage is completely eliminated. In addition, preferred stockholders have class voting rights on certain matters, including changes in fundamental investment restrictions and conversion to open-end status, and accordingly can veto any such changes. Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of our common stock and preferred stock, both by the 1940 Act and by requirements imposed by rating agencies or the terms of our credit facilities, might impair our ability to maintain our qualification as a RIC for federal income tax purposes. While we would intend to redeem our preferred stock to the extent necessary to enable us to distribute our income as required to maintain our qualification as a RIC, there can be no assurance that such actions could be effected in time to meet the tax requirements.

RISKS RELATING TO AN INVESTMENT IN OUR COMMON STOCK

Investing in our securities may involve an above average degree of risk.

The investments we make in accordance with our investment objective may result in a higher amount of risk than alternative investment options and volatility or loss of principal. Our investments in portfolio companies may be highly speculative and aggressive, therefore, an investment in our securities may not be suitable for someone with a low risk tolerance.

There is a risk that investors in our equity securities may not receive dividends or that our dividends may not grow over time and that investors in our debt securities may not receive all of the interest income to which they are entitled.

We intend to make distributions on a quarterly basis to our stockholders out of assets legally available for distribution. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. In addition, we may be limited in our ability to make distributions. Finally, if more stockholders opt to receive cash dividends rather than participate in our dividend reinvestment plan, we may be forced to liquidate some of our investments and raise cash in order to make dividend payments.

Our shares may trade at discounts from net asset value or at premiums that are unsustainable over the long term.

Shares of business development companies may trade at a market price that is less than the net asset value that is attributable to those shares. The possibility that our shares of common stock will trade at a discount from net asset value or at a premium that is unsustainable over the long term are separate and distinct from the risk that our net asset value will decrease. It is not possible to predict whether the shares offered hereby will trade at, above, or below net asset value.

The market price of our securities may fluctuate significantly.

The market price and liquidity of the market for our securities may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include:

volatility in the market price and trading volume of securities of business development companies or other companies in our sector, which are not necessarily related to the operating performance of these companies;

changes in regulatory policies or tax guidelines, particularly with respect to RICs or business development companies;

loss of RIC status;

changes in earnings or variations in operating results;

changes in the value of our portfolio of investments;

any shortfall in revenue or net income or any increase in losses from levels expected by investors or securities analysts;

departure of AIM's key personnel;

operating performance of companies comparable to us;

general economic trends and other external factors; and

loss of a major funding source.

We may allocate the net proceeds from this offering in ways with which you may not agree.

We have significant flexibility in investing the net proceeds of this offering and may use the net proceeds from this offering in ways with which you may not agree or for purposes other than those contemplated at the time of the offering.

We may be unable to invest the net proceeds raised from offerings on acceptable terms, which would harm our financial condition and operating results.

Until we identify new investment opportunities, we intend to either invest the net proceeds of future offerings in interest-bearing deposits or other short-term instruments or use the net proceeds from such offerings to reduce then-outstanding obligations under our credit facility. We cannot assure you that we will be able to find enough appropriate investments that meet our investment criteria or that any investment we complete using the proceeds from an offering will produce a sufficient return.

Sales of substantial amounts of our securities may have an adverse effect on the market price of our securities.

Sales of substantial amounts of our securities, or the availability of such securities for sale, could adversely affect the prevailing market prices for our securities. If this occurs and continues, it could impair our ability to raise additional capital through the sale of securities should we desire to do so.

USE OF PROCEEDS

We intend to use the net proceeds from selling securities pursuant to this prospectus for general corporate purposes, which include investing in portfolio companies in accordance with our investment objective and strategies. We anticipate that substantially all of the net proceeds of an offering of securities pursuant to this prospectus will be used within two years, depending on the availability of appropriate investment opportunities consistent with our investment objective and market conditions. Our portfolio currently consists primarily of senior loans, mezzanine loans and equity securities. Pending our investments in new debt investments, we plan to invest a portion of the net proceeds from an offering in cash equivalents, U.S. government securities and other high-quality debt investments that mature in one year or less from the date of investment, to reduce then-outstanding obligations under our credit facility, or for other general corporate purposes. The management fee payable by us will not be reduced while our assets are invested in such securities. See "Regulation—Temporary investments" for additional information about temporary investments we may make while waiting to make longer-term investments in pursuit of our investment objective. The supplement to this prospectus relating to an offering will more fully identify the use of the proceeds from such offering.

DIVIDENDS

We intend to continue to distribute quarterly dividends to our stockholders. Our quarterly dividends, if any, will be determined by our board of directors.

We have elected to be taxed as a RIC under Subchapter M of the Code. To maintain our RIC status, we must distribute at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of the assets legally available for distribution. In order to avoid certain excise taxes we must distribute during each calendar year an amount at least equal to the sum of (1) 98% of our ordinary income for the calendar year, (2) 98% of our capital gains in excess of capital losses for the one-year period ending on October 31st and (3) any ordinary income and net capital gains for preceding years that were not distributed during such years. In addition, although we currently intend to distribute realized net capital gains (i.e., realized net long-term capital gains in excess of realized net short-term capital losses), if any, at least annually, out of the assets legally available for such distributions, we may in the future decide to retain such capital gains for investment. In such event, the consequences of our retention of net capital gains are as described under "Material U.S. Federal Income Tax Considerations."

We maintain an "opt out" dividend reinvestment plan for our common stockholders. As a result, if we declare a dividend, then stockholders' cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically "opt out" of the dividend reinvestment plan so as to receive cash dividends. See "Dividend Reinvestment Plan."

We may not be able to achieve operating results that will allow us to make dividends and distributions at a specific level or to increase the amount of these dividends and distributions from time to time. In addition, we may be limited in our ability to make dividends and distributions due to the asset coverage test for borrowings when applicable to us as a BDC under the 1940 Act and due to provisions in future credit facilities. If we do not distribute a certain percentage of our income annually, we will suffer adverse tax consequences, including possible loss of our RIC status. We cannot assure stockholders that they will receive any dividends and distributions or dividends and distributions at a particular level.

The following table lists the quarterly dividends per share since shares of our common stock began being regularly quoted on The Nasdaq Global Select Market.

FORWARD-LOOKING STATEMENTS

Some of the statements in this prospectus constitute forward-looking statements, which relate to future events or our future performance or financial condition. The forward-looking statements contained in this prospectus involve risks and uncertainties, including statements as to:

our future operating results;

our business prospects and the prospects of our portfolio companies;

the impact of investments that we expect to make;

our contractual arrangements and relationships with third parties;

the dependence of our future success on the general economy and its impact on the industries in which we invest;

the ability of our portfolio companies to achieve their objectives;

our expected financings and investments;

the adequacy of our cash resources and working capital; and

We generally use words such as "anticipates," "believes," "expects," "intends" and similar expressions to identify forward-looking statements. Our actual results could differ materially from those projected in the forward-looking statements for any reason, including the factors set forth in "Risk Factors" and elsewhere in this prospectus.

We have based the forward-looking statements included in this prospectus on information available to us on the date of this prospectus, and we assume no obligation to update any such forward-looking statements. Although we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, you are advised to consult any additional disclosures that we may make directly to you or through reports that we in the future may file with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.

MANAGEMENT'S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our financial statements and related notes and other financial information appearing elsewhere in this prospectus. In addition to historical information, the following discussion and other parts of this prospectus contain forward-looking information that involves risks and uncertainties. Our actual results could differ materially from those anticipated by such forward-looking information due to the factors discussed under "Risk Factors" and "Forward-Looking Statements" appearing elsewhere in this prospectus.

OVERVIEW

We were incorporated under the Maryland General Corporation Law in February 2004. We have elected to be treated as a BDC under the 1940 Act. As such, we are required to comply with certain regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in "qualifying assets," including securities of private or thinly traded public U.S. companies, cash equivalents, U.S. government securities and high-quality debt investments that mature in one year or less. In addition, for federal income tax purposes we have elected to be treated as a RIC under Subchapter M of the Code. Pursuant to this election and assuming we qualify as a RIC, we generally do not have to pay corporate-level federal income taxes on any income we distribute to our stockholders. We commenced operations on April 8, 2004 upon completion of our initial public offering that raised $870 million in net proceeds selling 62 million shares of our common stock at a price of $15.00 per share. Since then, and through March 31, 2008, we have raised an additional $1 billion in net proceeds from additional offerings of common stock.

Investments

Our level of investment activity can and does vary substantially from period to period depending on many factors, including the amount of debt and equity capital available to middle market companies, the level of merger and acquisition activity for such companies, the general economic environment and the competitive environment for the types of investments we make.

As a BDC, we must not acquire any assets other than "qualifying assets" specified in the 1940 Act unless, at the time the acquisition is made, at least 70% of our total assets are qualifying assets (with certain limited exceptions). Qualifying assets include investments in "eligible portfolio companies." Pursuant to rules adopted over the past few years, the SEC expanded the definition of "eligible portfolio company" to include certain public companies that do not have any securities listed on a national securities exchange and companies that have securities listed on a national securities exchange but whose market capitalization is less than $250 million at the time of investment.

Revenue

We generate revenue primarily in the form of interest and dividend income from the debt and preferred securities we hold and capital gains, if any, on investment securities that we may acquire in portfolio companies. Our debt investments, whether in the form of mezzanine or senior secured loans, generally have a stated term of five to ten years and bear interest at a fixed rate or a floating rate usually determined on the basis of a benchmark: LIBOR, EURIBOR, GBP LIBOR, or the prime rate. While U.S. subordinated debt and corporate notes typically accrue interest at fixed rates, some of these investments may include zero coupon, payment-in-kind ("PIK") and/or step-up bonds that accrue income on a constant yield to call or maturity basis. Interest on debt securities is generally payable quarterly or semiannually. In some cases, some of our investments provide for deferred interest payments or PIK. The principal amount of the debt securities and any accrued but unpaid interest generally becomes due at the maturity date. In addition, we may generate revenue in the form of dividends paid to us on common equity investments as well as revenue in the form of commitment, origination, structuring fees, fees for providing managerial assistance and, if applicable, consulting fees, etc.

Expenses

All investment professionals of the investment adviser and their staff, when and to the extent engaged in providing investment advisory and management services to us, and the compensation and routine overhead expenses of that personnel which is allocable to those services are provided and paid for by AIM. We bear all other costs and expenses of our operations and transactions, including those relating to:

investment advisory and management fees;

expenses incurred by AIM payable to third parties, including agents, consultants or other advisors, in monitoring our financial and legal affairs and in monitoring our investments and performing due diligence on our prospective portfolio companies;

calculation of our net asset value (including the cost and expenses of any independent valuation firm);

direct costs and expenses of administration, including auditor and legal costs;

costs of preparing and filing reports or other documents with the SEC;

interest payable on debt, if any, incurred to finance our investments;

offerings of our common stock and other securities;

registration and listing fees;

fees payable to third parties, including agents, consultants or other advisors, relating to, or associated with, evaluating and making investments;

transfer agent and custodial fees;

taxes;

independent directors' fees and expenses;

marketing and distribution-related expenses;

the costs of any reports, proxy statements or other notices to stockholders, including printing and postage costs;

our allocable portion of the fidelity bond, directors and officers/errors and omissions liability insurance, and any other insurance premiums;

organization and offering; and

all other expenses incurred by us or AIA in connection with administering our business, such as our allocable portion of overhead under the administration agreement, including rent and our allocable portion of the cost of our chief financial officer and chief compliance officer and their respective staffs.

We expect our general and administrative operating expenses related to our ongoing operations to increase moderately in dollar terms, but decline slightly as a percentage of our total assets in future periods if our assets grow. Incentive fees, interest expense and costs relating to future offerings of securities, among others, would be additive.

The SEC requires that "Total annual expenses" be calculated as a percentage of net assets in the chart on page 5 rather than as a percentage of total assets. Total assets includes net assets as of March 31, 2008, anticipated net proceeds from this offering and assets that have been funded with borrowed monies (leverage). For reference, the below chart illustrates our "Total annual expenses" as a percentage of total assets:

Estimated annual expenses (as percentage of total assets):
Management fees	2.00 % (1)
Incentive fees payable under investment advisory and management agreement (20% of pre-incentive feenet investment income in excess of hurdle and 20% of net realized capital gains, net of grossunrealized capital losses)	0.82 % (2)
Other expenses	0.27 % (3)
Interest and other credit facility related expenses on borrowed funds	1.50 % (4)
Total annual expenses as a percentage of total assets	4.59% (1) (2) (3) (4)

______________

Assumes that annual incentive fees earned by our investment adviser, AIM, remain consistent with the incentive fees earned by AIM for the fiscal year ended March 31, 2008. AIM earns incentive fees consisting of two parts. The first part, which is payable quarterly in arrears, is based on our pre-incentive fee net investment income for the immediately preceding calendar quarter. Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets at the end of the immediately preceding calendar quarter, is compared to the hurdle rate of 1.75% quarterly (7% annualized). Our net investment income used to calculate this part of the incentive fee is also included in the amount of our gross assets used to calculate the 2% base management fee (see footnote 1 above). Accordingly, we pay AIM an incentive fee as follows: (1) no incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the hurdle rate; (2) 100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875% in any calendar quarter; and (3) 20% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter. These calculations are appropriately pro rated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter. You should be aware that a rise in the general level of interest rates can be expected to lead to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates would make it easier for us to meet or exceed the incentive fee hurdle rate and may result in a substantial increase of the amount of incentive fees payable to our investment adviser with respect to pre-incentive fee net investment income. The second part of the incentive fee will equal 20% of our realized capital gains for the calendar year, if any, computed net of all realized capital losses and unrealized capital depreciation (and incorporating unrealized depreciation on a gross investment-by-investment basis) and is payable in arrears at the end of each calendar year. For a more detailed discussion of the calculation of this fee, see "Management—Investment Advisory and Management Agreement" in this base prospectus.

Portfolio and Investment Activity

During our fiscal year ended March 31, 2008, we invested $1.8 billion, across 27 new and numerous existing portfolio companies. This compares to investing $1.4 billion in 24 new and several existing portfolio companies for the previous fiscal year ended March 31, 2007. Investments sold or prepaid during the fiscal year ended March 31, 2008 totaled $714 million versus $845 million for the fiscal year ended March 31, 2007.

The weighted average yields on our senior secured loan portfolio, subordinated debt portfolio and total debt portfolio at our current cost basis were 10.0%, 12.8% and 12.0%, respectively, at March 31, 2008. At March 31, 2007, the yields were 12.3%, 13.5%, and 13.1%, respectively.

Since the initial public offering of Apollo Investment Corporation in April 2004 and through March 31, 2008, total invested capital exceeds $5.2 billion in 112 portfolio companies. Over the same period, Apollo Investment has also completed transactions with 80 different financial sponsors.

Senior secured loans and European mezzanine loans typically accrue interest at variable rates determined on the basis of a benchmark: LIBOR, EURIBOR, GBP LIBOR, or the prime rate, with stated maturities at origination that typically range from 5 to 10 years. While subordinated debt issued within the United States will typically accrue interest at fixed rates, some of these investments may include zero-coupon, PIK and/or step bonds that accrue income on a constant yield to call or maturity basis. At March 31, 2008, 62% or $1.6 billion of our interest-bearing investment portfolio is fixed rate debt and 38% or $1.0 billion is floating rate debt. At March 31, 2007, 64% or $1.4 billion of our interest-bearing investment portfolio was fixed rate debt and 36% or $0.8 billion was floating rate debt.

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Changes in the economic environment, financial markets and any other parameters used in determining such estimates could cause actual results to differ materially. In addition to the discussion below, our critical accounting policies are further described in the notes to the financial statements.

Valuation of Portfolio Investments

As a BDC, we generally invest in illiquid or thinly traded securities including debt and equity securities of middle market companies. Under procedures established by our Board of Directors, we value investments, including certain subordinated debt, senior secured debt and other debt securities with maturities greater than 60 days, for which market quotations are readily available, at such market quotations unless they are deemed not to represent fair value. We obtain market quotations from independent pricing services or use the mean between the bid and ask prices obtained from at least two brokers or dealers (if available, otherwise by a principal market maker or a primary market dealer). From time to time, we may also utilize independent third party valuation firms to determine fair value if and when such market quotations are deemed not to represent fair value. Debt and equity securities that are not publicly traded or whose market prices are not readily available are valued at fair value as determined in good faith by or under the direction of our Board of Directors. Such determination of fair values may involve subjective judgments and estimates. Investments purchased within 60 days of maturity are valued at cost plus accreted discount, or minus amortized premium, which approximates value. With respect to unquoted securities, our board of directors, together with our independent valuation advisers value each investment considering, among other measures, discounted cash flow models, comparisons of financial ratios of peer companies that are public and other factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, our board, together with our independent valuation advisers consider the pricing indicated by the external event to corroborate and/or assist us in our valuation. Because we expect that there will not be a readily available market for many of the investments in our portfolio, we expect to value many of our portfolio investments at fair value as determined in good faith by or under the direction of our Board of Directors pursuant to a valuation policy and a consistently applied valuation process utilizing the input of the investment adviser, independent valuation firms and the audit committee. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available fair market value, the value of our investments may differ

significantly from the values that would have been used had a readily available market value existed for such investments, and the differences could be material.

With respect to investments for which market quotations are not readily available or when such market quotations are deemed not to represent fair value, our board of directors has approved a multi-step valuation process each quarter, as described below:

(1) our quarterly valuation process begins with each portfolio company or investment being initially valued by the investment professionals of our investment adviser responsible for the portfolio investment;

(2) preliminary valuation conclusions are then documented and discussed with senior management of our investment adviser;

(3) independent valuation firms engaged by our board of directors conduct independent appraisals and review our investment adviser’s preliminary valuations and make their own independent assessment;

(4) the audit committee of the board of directors reviews the preliminary valuation of our investment adviser and that of the independent valuation firm and responds to the valuation recommendation of the independent valuation firm to reflect any comments; and

(5) the board of directors discusses valuations and determines the fair value of each investment in our portfolio in good faith based on the input of our investment adviser, the respective independent valuation firm and the audit committee.

In September, 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards ("SFAS") 157, Fair Value Measurements. This statement defines fair value, establishes a framework for measuring fair value in GAAP, and expands disclosures about fair value measurements. This statement is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those years. We have adopted this statement on a prospective basis beginning in the quarter ended June 30, 2008. Adoption of this statement did not have a material effect on our financial statements for the quarter ended June 30, 2008.

SFAS No. 157 classifies the inputs used to measure these fair values into the following hierarchy:

Level 1 : Quoted prices in active markets for identical assets or liabilities, accessible by us at the measurement date.

Level 2 : Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active, or other observable inputs other than quoted prices.

Level 3 : Unobservable inputs for the asset or liability.

In all cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each investment.

Revenue Recognition

We record interest and dividend income on an accrual basis to the extent that we expect to collect such amounts. For loans and securities with contractual PIK interest or dividends, which represents contractual interest or dividends accrued and added to the loan balance that generally becomes due at maturity, we may not accrue PIK income if the portfolio company valuation indicates that the PIK income is not collectible. We do not accrue as a receivable interest or dividends on loans and securities if we have reason to doubt our ability to collect such income. Loan origination fees, original issue discount, and market discount are capitalized and then we amortize such amounts as interest income. Upon the prepayment of a loan or security, any unamortized loan origination fees are recorded as interest income. We record prepayment premiums on loans and securities as interest income when we receive such amounts.

Net Realized Gains or Losses and Net Change in Unrealized Appreciation or Depreciation

We measure realized gains or losses by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment, without regard to unrealized appreciation or depreciation previously recognized, but considering unamortized upfront fees and prepayment penalties. Net change in unrealized appreciation or depreciation reflects the change in portfolio investment values during the reporting period, including the reversal of previously recorded unrealized appreciation or depreciation, when gains or losses are realized.

Within the context of these critical accounting policies, we are not currently aware of any reasonably likely events or circumstances that would result in materially different amounts being reported.

RESULTS OF OPERATIONS

Results comparisons are for the fiscal years ended March 31, 2008, March 31, 2007 and March 31, 2006.

Investment Income

For the fiscal years ended March 31, 2008, March 31, 2007 and March 31, 2006, gross investment income totaled $357.9 million, $266.1 million and $152.8 million, respectively. The continued increase in gross investment income for fiscal years 2007 and 2008 was primarily due to the growth of our investment portfolio as compared to previous fiscal periods. Origination, closing and/or commitment fees associated with investments in portfolio companies are accreted into interest income over the respective terms of the applicable loans.

Expenses

Net expenses totaled $154.4 million, $139.7 million and $63.7 million, respectively, for the fiscal years ended March 31, 2008, March 31, 2007 and March 31, 2006, of which $30.4 million, $57.9 million and $22.3 million, respectively, were performance-based incentive fees and $55.8 million, $34.4 million and $13.0 million, respectively, were interest and other credit facility expenses. Net expenses exclusive of performance-based incentive fees and interest and other credit facility expenses for the years ended March 31, 2008, March 31, 2007 and March 31, 2006 were $68.2 million, $47.4 million and $28.4 million, respectively. Of these expenses, general and administrative expenses totaled $8.3 million, $6.8 million and $5.0 million, respectively, for the fiscal years ended March 31, 2008, 2007 and 2006. In addition, excise tax expense totaled $1.9 million, $1.1 million, and $0 for the fiscal years ended March 31, 2008, 2007 and 2006. Expenses consist of base investment advisory and management fees, insurance expenses, administrative services fees, professional fees, directors' fees, audit and tax services expenses, and other general and administrative expenses. The increases in net expenses from fiscal 2006 to 2007 and fiscal 2007 to 2008 were primarily related to increases in base management fees and other general and administrative expenses related to the growth of our investment portfolio as compared to the previous periods.

Net Investment Income

Our net investment income totaled $201.6 million, $125.3 million and $89.1 million, respectively, for the fiscal years ended March 31, 2008, 2007 and 2006.

Net Realized Gains

We had investment sales and prepayments totaling $714 million, $845 million and $452 million, respectively, for the fiscal years ended March 31, 2008, 2007 and 2006. Net realized gains for the fiscal years ended March 31, 2008, 2007 and 2006 were $54.3 million, $132.9 million and $11.2 million, respectively. The significant increase in net realized gains from fiscal year 2006 to fiscal year 2007 was primarily due to a gain of $107.6 million realized from GS Prysmian Co-Invest LP (pursuant to a sale and purchase agreement dated as of January 24, 2007, along with the GS Funds, GS Prysmian Co-Invest LP agreed to sell its remaining equity securities it owned in Prysmian (Lux) Sarl to a newly created entity for cash and equity securities consideration totaling € 85.6 million).

Net Unrealized Appreciation (Depreciation) on Investments, Cash Equivalents and Foreign Currencies

For the fiscal year ended March 31, 2008 net unrealized appreciation on our investments, cash equivalents, foreign currencies and other assets and liabilities decreased $289.3 million. For the fiscal years ended

March 31, 2007 and 2006, net unrealized appreciation on our investments, cash equivalents, foreign currencies and other assets and liabilities increased $54.0 million and $20.1 million, respectively. At March 31, 2008, net unrealized depreciation totaled $197.1 million versus net unrealized appreciation of $92.2 million at March 31, 2007.

Net Increase (Decrease) in Net Assets From Operations

For the fiscal year ended March 31, 2008, we had a net decrease in net assets resulting from operations of $33.4 million. For the fiscal years ended March 31, 2007 and 2006, we had a net increase in net assets resulting from operations of $312.2 million and $120.4 million, respectively. The net decrease in net assets from operations per share was $0.30 for the year ended March 31, 2008. For the years ended March 31, 2007 and 2006, the net increase in net assets from operations per share was $3.64 and $1.90, respectively.

LIQUIDITY AND CAPITAL RESOURCES

On September 18, 2007, we closed on a public offering of 14.95 million shares of common stock at $20.00 per share raising approximately $285.5 million in net proceeds. Our liquidity and capital resources are also generated and available through its senior secured, multi-currency $1.7 billion, five-year, revolving credit facility maturing in April 2011 as well as from cash flows from operations, investment sales and prepayments of senior and subordinated loans and income earned from investments and cash equivalents. At March 31, 2008, we have $1.6 billion in borrowings outstanding and $0.1 billion remaining unused. In addition, we held cash and cash equivalents on its balance sheet totaling $415.0 million. In the future, we may raise additional equity or debt capital off its shelf registration or may securitize a portion of its investments among other considerations. The primary use of funds will be investments in portfolio companies, cash distributions to our stockholders and for other general corporate purposes. In addition, on May 16, 2008, we closed on a public offering of 22.3 million shares of common stock at $17.11 per share raising approximately $369.6 million in net proceeds.

Contractual Obligations

We have entered into two contracts under which we have future commitments: the investment advisory and management agreement, pursuant to which Apollo Investment Management has agreed to serve as our investment adviser, and the administration agreement, pursuant to which Apollo Administration has agreed to furnish us with the facilities and administrative services necessary to conduct our day-to-day operations and provide on our behalf managerial assistance to those portfolio companies to which we are required to provide such assistance. Payments under the investment advisory and management agreement are equal to (1) a percentage of the value of our gross assets and (2) a two-part incentive fee. Payments under the administration agreement are equal to an amount based upon our allocable portion of Apollo Administration's overhead in performing its obligations under the administration agreement, including rent, technology systems, insurance and our allocable portion of the costs of our chief financial officer and chief compliance officer and their respective staffs. Either party may terminate each of the investment advisory and management agreement and administration agreement without penalty upon not more than 60 days' written notice to the other. Please see Note 3 within our financial statements for more information.

Off-Balance Sheet Arrangements

On February 28, 2007, we entered into Senior Secured Term Loan agreements with Gray Wireline Service Inc., resulting in investments of $40 million in a First Out Term Loan and $70 million in a Second Out Term Loan. In connection with the transaction, we also committed to $27.5 million of additional delay draw commitments under the term loans subject to various contingencies and draw down tests. As of March 31, 2008,

we had $20.0 million of delay draw commitments remaining. Effective April 9, 2008, the remaining commitments were terminated by Gray Wireline Service Inc.

We have the ability to issue standby letters of credit through its revolving credit facility. As of March 31, 2008 and March 31, 2007, we had issued through JPMorgan Chase Bank, N.A. standby letters of credit totaling $14,435 and $0, respectively.

At March 31, 2008, we did not have any additional off-balance sheet liabilities or other contractual obligations that are reasonably likely to have a current or future material effect on our financial condition, other than the investment advisory and management agreement and the administration agreement described above.

Dividends

Dividends paid to stockholders for the fiscal years ended March 31, 2008, 2007 and 2006 totaled $230.9 million or $2.07 per share, $168.4 million or $1.93 per share, and $102.7 million or $1.63 per share, respectively. The following table summarizes our quarterly dividends paid to stockholders for the fiscal years ended March 31, 2008, 2007, and 2005, respectively:

	Declared Dividends
Fiscal Year Ended March 31, 2008
Fourth Fiscal Quarter	$	0.52
Third Fiscal Quarter	$	0.52
Second Fiscal Quarter	$	0.52
First Fiscal Quarter	$	0.51

Third Fiscal Quarter	$	0.44
Second Fiscal Quarter	$	0.43
First Fiscal Quarter	$	0.31

Tax characteristics of all dividends will be reported to stockholders on Form 1099 after the end of the calendar year.

We intend to continue to distribute quarterly dividends to our stockholders. Our quarterly dividends, if any, will be determined by our board of directors.

consequences, including possible loss of our RIC status. We cannot assure stockholders that they will receive any dividends and distributions or dividends and distributions at a particular level.

With respect to the dividends paid to stockholders, income from origination, structuring, closing, commitment and other upfront fees associated with investments in portfolio companies is treated as taxable income and accordingly, distributed to stockholders. For the fiscal years ended March 31, 2008, 2007 and 2006 upfront fees totaling $0.1 million, $8.3 million and $5.8 million, respectively, are being amortized into income over the lives of their respective loans to the extent such loans remain outstanding.

Quantitative and Qualitative Disclosure about Market Risk

We are subject to financial market risks, including changes in interest rates. During the fiscal year ended March 31, 2008, many of the loans in our portfolio had floating interest rates. These loans are usually based on a floating LIBO rate and typically have durations of one to six months after which they reset to current market interest rates. As the percentage of our mezzanine and other subordinated loans increase as a percentage of our total investments, we expect that more of the loans in our portfolio will have fixed rates. Accordingly, we may hedge against interest rate fluctuations by using standard hedging instruments such as futures, options, swaps and forward contracts subject to the requirements of the 1940 Act. While hedging activities may insulate us against adverse changes in interest rates, they may also limit our ability to participate in the benefits of lower interest rates with respect to our portfolio of investments. During the fiscal year ended March 31, 2008, we did not engage in interest rate hedging activities.

BUSINESS

Apollo Investment

Apollo Investment Corporation, a Maryland corporation organized on February 2, 2004, is a closed-end, non-diversified management investment company that has filed an election to be treated as a BDC under the 1940 Act. In addition, for tax purposes we have elected to be treated as a RIC.

Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in middle-market companies in the form of mezzanine and senior secured loans, as well as by making equity investments in companies. From time to time, we may also invest in the securities of public companies as well as public companies whose securities are thinly traded.

We believe that our investment adviser is able to leverage the overall Apollo Global Management investment platform, resources and existing relationships with financial sponsors, financial institutions and other investment firms to provide us with attractive investments. In addition to deal flow, the Apollo investment platform assists our investment adviser in analyzing, structuring and monitoring investments. Apollo's senior partners have worked together for over 18 years and have substantial experience investing in senior loans, high yield bonds, mezzanine debt and private equity. We have access to the Apollo staff of approximately 175 professionals employed by Apollo who provide assistance in accounting, legal, compliance, technology and investor relations.

During our fiscal year ended March 31, 2008, we invested $1.8 billion across 27 new and several existing portfolio companies. This compares to investing $1.4 billion in 24 new and several existing portfolio companies for the previous fiscal year ended March 31, 2007. Investments sold or prepaid during the fiscal year ended March 31, 2008 totaled $714 million versus $845 million for the fiscal year ended March 31, 2007. Total invested capital since our initial public offering in April 2004 through March 31, 2008 exceeds $5.2 billion. The weighted average yields on our senior secured loan portfolio, subordinated debt portfolio and total debt portfolio at our current cost basis were 10.0%, 12.8% and 12.0%, respectively, at March 31, 2008. At March 31, 2007, the yields were 12.3%, 13.5%, and 13.1%, respectively.

Our targeted investment size typically ranges between $20 million and $250 million, although this investment size may vary proportionately as the size of our capital base changes. At March 31, 2008, our net portfolio consisted of 71 portfolio companies and was invested 22% in senior secured loans, 57% in subordinated debt, 6% in preferred equity and 15% in common equity and warrants versus 57 portfolio companies invested 26% in senior secured loans, 61% in subordinated debt, 4% in preferred equity and 9% in common equity and warrants at March 31, 2007.

Since the initial public offering of Apollo Investment in April 2004 and through March 31, 2008, total invested capital exceeds $5.2 billion in 112 portfolio companies. Over the same period, Apollo Investment has also completed transactions with 80 different financial sponsors.

At March 31, 2008, 62% or $1.6 billion of our interest-bearing investment portfolio is fixed rate debt and 38% or $1.0 billion is floating rate debt. At March 31, 2007, 64% or $1.4 billion of our interest-bearing investment portfolio was fixed rate debt and 36% or $0.8 billion was floating rate debt.

About Apollo

About Apollo Investment Management

AIM, our investment adviser, is led by a dedicated and growing team of investment professionals and is further supported by Apollo's team of more than 175 professionals as of March 31, 2008. AIM's investment committee currently consists of John J. Hannan, the Chairman of our board of directors, our Chief Executive Officer and Chairman of AIM's investment committee; James C. Zelter, our President and Chief Operating Officer and a Vice President of the general partner of AIM; Patrick J. Dalton, our Executive Vice President and a Vice President of the general partner of AIM; and José Briones, a Vice President of the general partner of AIM. The composition of the Investment Committee of AIM may change from time to time. AIM draws upon Apollo's 18-year history and benefits from the Apollo investment professionals' significant capital markets, trading and research expertise developed through investments in many core industry sectors in over 150 companies since inception.

About Apollo Investment Administration

In addition to furnishing us with office facilities, equipment, and clerical, bookkeeping and record keeping services, AIA also oversees our financial records as well as the preparation of our reports to stockholders and reports filed with the SEC. AIA oversees the determination and publication of our net asset value, oversees the preparation and filing of our tax returns, and generally monitors the payment of our expenses and the performance of administrative and professional services rendered to us by others. Furthermore, AIA would provide on our behalf managerial assistance to those portfolio companies to which we are required to provide such assistance.

Operating and Regulatory Structure

Our investment activities are managed by AIM and supervised by our board of directors, a majority of whom are independent of Apollo and its affiliates. AIM is an investment adviser that is registered under the Advisers Act. Under our investment advisory and management agreement, we pay AIM an annual base management fee based on our gross assets as well as an incentive fee based on our performance.

As a BDC, we are required to comply with certain regulatory requirements. Also, while we are permitted to finance investments using debt, our ability to use debt is limited in certain significant respects. We have elected to be treated for federal income tax purposes as a RIC under Subchapter M of the Code.

Investments

Apollo Investment seeks to create a portfolio that includes primarily debt investments in mezzanine, senior secured loans and, to a lesser extent, private equity by generally investing approximately $20 million to $250 million of capital, on average, in the securities of middle-market companies. The average investment size will vary as the size of our capital base varies. Our target portfolio will generally be more heavily weighted toward mezzanine loans. Structurally, mezzanine loans usually rank subordinate in priority of payment to senior debt, such as senior bank debt, and are often unsecured. As such, other creditors may rank senior to us in the event of an insolvency. However, mezzanine loans rank senior to common and preferred equity in a borrowers' capital structure. Mezzanine loans may have a fixed or floating interest rate. Additional upside can be generated from upfront fees, call protection including call premiums, equity co-investments or warrants. We believe that mezzanine loans offer an attractive investment opportunity based upon their historic returns and resilience during economic downturns.

Additionally, we may acquire investments in the secondary market if we believe the risk-adjusted returns are attractive.

Our principal focus is to provide capital to middle-market companies in a variety of industries. We generally seek to target companies that generate positive free cash flows. We also generally seek to invest in companies from the broad variety of industries in which Apollo's investment professionals have direct expertise.

The following is a representative list of the industries in which Apollo has invested:

Building materials

Business services

Cable television

Chemicals

Communications

Consumer products

Distribution

Education

Energy/Utilities

Environmental services

Financial services

Food

Healthcare

Lodging/Leisure/Resorts

Manufacturing/Basic industry

Media

Packaging

Printing and publishing

Restaurants

Retail

Transportation

We may also invest in other industries if we are presented with attractive opportunities.

In an effort to increase our returns and the number of loans that we can make, we may in the future seek to securitize our loans. To securitize loans, we may create a wholly – owned subsidiary and contribute a pool of loans to the subsidiary. We may sell interests in the subsidiary on a non-recourse basis to purchasers whom we would expect to be willing to accept a lower interest rate to invest in investment-grade loan pools. We may use the proceeds of such sales to pay down bank debt or to fund additional investment.

We may invest, to the extent permitted by law, in the securities and instruments of other investment companies, including private funds. We may also co-invest on a concurrent basis with affiliates of ours, subject to compliance with applicable regulations and our allocation procedures. Certain types of negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance that any such order will be obtained.

At March 31, 2008, our net portfolio consisted of 71 portfolio companies and was invested 57% in subordinated debt, 6% in preferred equity, 15% in common equity and warrants and 22% in senior secured loans. We expect that our portfolio will continue to include primarily mezzanine loans, and to a lesser extent, senior secured loans, and equity-related securities.

While our primary focus is to generate both current income and capital appreciation through investments in loans and debt securities both senior and subordinated, and private equity, we may invest a portion of the portfolio in opportunistic investments, such as foreign securities.

Investment Selection

We are committed to the same value oriented philosophy used by the investment professionals of Apollo in Apollo's private investment funds and will commit resources to managing downside exposure.

Prospective portfolio company characteristics

We have identified several criteria that we believe are important in identifying and investing in prospective portfolio companies. These criteria provide general guidelines for our investment decisions; however, we caution you that not all of these criteria will be met by each prospective portfolio company in which we choose to invest. Generally, we seek to utilize our access to information generated by our investment professionals to identify investment candidates and to structure investments quickly and effectively.

Value orientation/positive cash flow

Our investment philosophy places a premium on fundamental analysis from an investor's perspective and has a distinct value orientation. We focus on companies in which we can invest at relatively low multiples of operating cash flow and that are profitable at the time of investment on an operating cash flow basis. Typically, we do not expect to invest in start-up companies or companies having speculative business plans.

Experienced management

We generally require that our portfolio companies have an experienced management team. We also require the portfolio companies to have in place proper incentives to induce management to succeed and to act in concert with our interests as investors, including having significant equity interests.

Strong competitive position in industry

We seek to invest in target companies that have developed leading market positions within their respective markets and are well positioned to capitalize on growth opportunities. We seek companies that demonstrate significant competitive advantages versus their competitors, which should help to protect their market position and profitability.

Exit strategy

We seek to invest in companies that we believe will provide a steady stream of cash flow to repay our loans. We expect that such internally generated cash flow, leading to the payment of interest on, and the repayment of the principal of, our investments in portfolio companies to be a key means by which we exit from our investments over time. In addition, we seek to invest in companies whose business models and expected future cash flows offer attractive exit possibilities. These companies include candidates for strategic acquisition by other industry participants and companies that may repay our investments through an initial public offering of common stock or another capital market transaction.

Liquidation value of assets

The prospective liquidation value of the assets, if any, collateralizing loans in which we invest is an important factor in our credit analysis. We emphasize both tangible assets, such as accounts receivable, inventory, equipment and real estate, and intangible assets, such as intellectual property, customer lists, networks and databases.

Due diligence

Our investment adviser conducts diligence on prospective portfolio companies consistent with the approach adopted by the investment professionals of Apollo. We believe that Apollo's investment professionals have a reputation for conducting extensive due diligence investigations in their investment activities. In conducting their due diligence, Apollo's investment professionals use publicly available information as well as information from their extensive relationships with former and current management teams, consultants, competitors and investment bankers and the direct experience of the senior partners of Apollo.

Our due diligence will typically include:

review of historical and prospective financial information;

on-site visits;

interviews with management, employees, customers and vendors of the potential portfolio company;

review of senior loan documents;

background checks; and

research relating to the company's management, industry, markets, products and services, and competitors.

Additional due diligence with respect to any investment may be conducted on our behalf by attorneys and independent accountants prior to the closing of the investment, as well as other outside advisors, as appropriate.

Upon the completion of due diligence and a decision to proceed with an investment in a company, the professionals leading the investment present the investment opportunity to our investment adviser's investment committee, which determines whether to pursue the potential investment.

The investment committee

All new investments by us must be approved by the investment committee of AIM. The members of the investment committee receive no compensation from us. Such members are employees or partners of AIM and receive compensation or profit distributions from AIM, and in certain instances, from other Apollo affiliates. The members of the investment committee are listed below.

John J. Hannan Chairman of the board of directors, Chief Executive Officer and Director of Apollo Investment and a Vice President of AIM . Mr. Hannan became a director of Apollo Investment in March 2004 and was elected our Chief Executive Officer in February 2006 and Chairman of the board of directors in August 2006. Mr. Hannan has served on AIM's investment committee since February 2006. Mr. Hannan, a senior partner of Apollo, co-founded Apollo Management, L.P. in 1990 and Apollo Real Estate Advisers, L.P. (an investment manager affiliated with Apollo's real estate investment funds) in 1993.

Investment structure

Once we have determined that a prospective portfolio company is suitable for investment, we work with the management of that company and its other capital providers, including senior, junior and equity capital providers, to structure an investment.

We seek to structure our mezzanine investments primarily as unsecured, subordinated loans that provide for relatively high interest rates that provide us with significant current interest income. These loans typically have interest-only payments in the early years, with amortization of principal deferred to the later years of the mezzanine loans. In some cases, we may enter into loans that, by their terms, convert into equity or additional debt securities or defer payments of interest after our investment. Also, in some cases our mezzanine loans may be collateralized by a

subordinated lien on some or all of the assets of the borrower. Typically, our mezzanine loans have maturities of five to ten years.

We also seek to invest in portfolio companies in the form of senior secured loans. We expect these senior secured loans to have terms of three to ten years and may provide for deferred interest payments over the term of the loan. We generally seek to obtain security interests in the assets of our portfolio companies that serve as collateral in support of the repayment of these loans. This collateral may take the form of first or second priority liens on the assets of a portfolio company. We expect that the interest rate on our senior secured loans generally will range between 2% and 10% over the London Interbank Offer Rate, or LIBOR.

In the case of our mezzanine and senior secured loan investments, we seek to tailor the terms of the investment to the facts and circumstances of the transaction and the prospective portfolio company, negotiating a structure that protects our rights and manages our risk while creating incentives for the portfolio company to achieve its business plan and improve its profitability. For example, in addition to seeking a senior position in the capital structure of our portfolio companies, we seek to limit the downside potential of our investments by:

requiring an expected total return on our investments (including both interest and potential equity appreciation) that compensates us for credit risk;

generally incorporating call protection into the investment structure; and

negotiating covenants and information rights in connection with our investments that afford our portfolio companies as much flexibility in managing their businesses as possible, consistent with our goal of preserving our capital. Such restrictions may include affirmative and negative covenants, default penalties, lien protection, change of control provisions and board rights, including either observation or participation rights.

Our investments may include equity features, such as warrants or options to buy a minority interest in the portfolio company. Any warrants we receive with our debt securities generally require only a nominal cost to exercise, and thus, as a portfolio company appreciates in value, we may achieve additional investment return from this equity interest. We may structure the warrants to provide provisions protecting our rights as a minority- interest holder, as well as puts, or rights to sell such securities back to the company, upon the occurrence of specified events. In many cases, we may also seek to obtain registration rights in connection with these equity interests, which may include demand and "piggyback" registration rights.

We expect to hold most of our investments to maturity or repayment, but we may sell certain of our investments earlier, including, if a liquidity event takes place such as the sale or recapitalization or worsening of credit quality of a portfolio company.

Managerial assistance

As a BDC, we offer, and must provide upon request, managerial assistance to our portfolio companies. This assistance could involve, among other things, monitoring the operations of our portfolio companies, participating in board and management meetings, consulting with and advising officers of portfolio companies and providing other organizational and financial guidance. We may receive fees for these services. AIA provides such managerial assistance on our behalf to portfolio companies that request this assistance.

Ongoing relationships with portfolio companies

Monitoring

AIM monitors our portfolio companies on an ongoing basis. AIM monitors the financial trends of each portfolio company to determine if each is meeting its respective business plans and to assess the appropriate course of action for each company.

AIM has several methods of evaluating and monitoring the performance and fair value of our investments, which can include, but are not limited to, the following:

Assessment of success in adhering to portfolio company's business plan and compliance with covenants;

Periodic and regular contact with portfolio company management and, if appropriate, the financial or strategic sponsor, to discuss financial position, requirements and accomplishments;

Comparisons to other portfolio companies in the industry;

Attendance at and participation in board meetings; and

Review of monthly and quarterly financial statements and financial projections for portfolio companies.

In addition to various risk management and monitoring tools, AIM also uses an investment rating system to characterize and monitor our expected level of returns on each investment in our portfolio.

We use an investment rating scale of 1 to 5. The following is a description of the conditions associated with each investment rating:

Investment Rating		Summary Description
1		Capital gain expected
2		Full return of principal and interest or dividend expected, with the portfolio company performing in accordance with our analysis of its business
3		Full return of principal and interest or dividend expected, but the portfolio company requires closer monitoring
4		Some loss of interest, dividend or capital appreciation expected, but still expecting an overall positive internal rate of return on the investment
5		Loss of interest or dividend and some loss of principal investment expected, which would result in an overall negative internal rate of return on the investment

AIM monitors and, when appropriate, changes the investment ratings assigned to each investment in our portfolio. In connection with our valuation process, AIM reviews these investment ratings on a quarterly basis, and our board of directors affirms such ratings.

Valuation Process

The following is a description of the steps we take each quarter to determine the value of our portfolio. Many of our portfolio investments are recorded at fair value as determined in good faith by or under the direction of our board of directors pursuant to a valuation policy and a consistently applied valuation process utilizing the input of our investment adviser, independent valuation firms and the audit committee. As a result, there is uncertainty as to the value of our portfolio investments. Investments for which market quotations are readily available are recorded in our financial statements at such market quotations if they are deemed to represent fair value. Market quotations may be deemed not to represent fair value in certain circumstances where AIM believes that facts and circumstances applicable to an issuer, a seller or purchaser or the market for a particular security causes current market quotes to not reflect the fair value of the security. Examples of these events could include cases in which material events are announced after the close of the market on which a security is primarily traded, when a security trades infrequently causing a quoted purchase or sale price to become stale or in the event of a "fire sale" by a distressed seller.

(2) preliminary valuation conclusions are then documented and discussed with senior management of our investment adviser;

When we make investments that involve deferrals of interest payable to us, any increase in the value of the investment due to the accrual or receipt of payment of interest is allocated to the increase in the cost basis of the investment, rather than to capital appreciation or gain.

Competition

Our primary competitors in providing financing to middle-market companies include public and private funds, commercial and investment banks, commercial financing companies, and, to the extent they provide an alternative form of financing, private equity funds. Additionally, because competition for investment opportunities generally has increased among alternative investment vehicles, such as hedge funds, those entities have begun to invest in areas they have not traditionally invested in, including investments in middle-market companies. As a result of these new entrants, competition for investment opportunities at middle-market companies has intensified. Some of our existing and potential competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, some competitors may have a lower cost of funds and access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than we. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC. We expect to use the industry information of Apollo's investment professionals to which we have access to assess investment risks and determine appropriate pricing for our investments in portfolio companies. In addition, we believe that the relationships of the senior managers of AIM and of the senior partners of Apollo, enable us to learn about, and compete effectively for, financing opportunities with attractive middle-market companies in the industries in which we seek to invest.

Staffing

We have a chief financial officer and a chief compliance officer and, to the extent necessary, they have hired and will continue to hire additional personnel. These individuals are employees of Apollo Administration and perform their respective functions under the terms of the administration agreement. Certain of our other executive officers are managing partners of our investment adviser. Our day-to-day investment operations are managed by our investment adviser. AIM has hired and will continue to hire additional investment professionals in the future. In addition, we reimburse AIA for our allocable portion of expenses incurred by it in performing its obligations under the administration agreement, including rent and our allocable portion of the cost of our chief financial officer and chief compliance officer and their respective staffs.

Properties

We do not own any real estate or other physical properties materially important to our operations. Our administrative and principal executive offices are located at 9 West 57th Street, New York, NY 10019. We believe that our office facilities are suitable and adequate for our business as it is contemplated to be conducted.

Legal Proceedings

We and AIM are not currently subject to any material legal proceedings.

Sarbanes-Oxley Act of 2002

The Sarbanes-Oxley Act of 2002 imposes a wide variety of regulatory requirements on publicly-held companies and their insiders. Many of these requirements affect us. For example:

Pursuant to Rule 13a-14 under the Securities Exchange Act of 1934 (the "Exchange Act"), our Chief Executive Officer and Chief Financial Officer must certify the accuracy of the financial statements contained in our periodic reports;

Pursuant to Item 307 of Regulation S-K, our periodic reports must disclose our conclusions about the effectiveness of our disclosure controls and procedures;

Pursuant to Rule 13a-15 under the Exchange Act, our management must prepare a report regarding its assessment of our internal control over financial reporting, which must be audited by our independent registered public accounting firm; and

Pursuant to Item 308 of Regulation S-K and Rule 13a-15 under the Exchange Act, our periodic reports must disclose whether there were significant changes in our internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses.

The Sarbanes-Oxley Act requires us to review our current policies and procedures to determine whether we comply with the Sarbanes-Oxley Act and the regulations promulgated thereunder. We will continue to monitor our compliance with all regulations that are adopted under the Sarbanes-Oxley Act and will take actions necessary to ensure that we are in compliance therewith.

COMMITTEES OF THE BOARD OF DIRECTORS

Audit committee

The Audit Committee operates pursuant to an Audit Committee Charter approved by the board of directors. The charter sets forth the responsibilities of the Audit Committee, which include selecting or retaining each year an independent registered public accounting firm (the "auditors") to audit our accounts and records; reviewing and discussing with management and the auditors our annual audited financial statements, including disclosures made in management's discussion and analysis, and recommending to the board of directors whether the audited financial statements should be included in our annual report on Form 10-K; reviewing and discussing with management and the auditors our quarterly financial statements prior to the filings of our quarterly reports on Form 10-Q; pre-approving the auditors' engagement to render audit and permissible non-audit services; and evaluating the qualifications, performance and independence of the auditors. The Audit Committee is presently composed of five persons: Ms. Malone (Chair) and Messrs. Puleo, Spielvogel, and Stein, all of whom are independent directors and are otherwise considered independent under the listing standards of NASDAQ Marketplace Rule 4200 (a)(15) (the "NASDAQ Listing Standards").

INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT

Management services

AIM serves as our investment adviser and is controlled by Apollo. AIM is registered as an investment adviser under the Advisers Act. Subject to the overall supervision of our board of directors, the investment adviser manages the day-to-day operations of, and provides investment advisory and management services to, Apollo Investment. Under the terms of an investment advisory and management agreement, AIM:

determines the composition of our portfolio, the nature and timing of the changes to our portfolio and the manner of implementing such changes;

identifies, evaluates and negotiates the structure of the investments we make (including performing due diligence on our prospective portfolio companies); and

closes and monitors the investments we make.

AIM's services under the investment advisory and management agreement are not exclusive, and it is free to furnish similar services to other entities so long as its services to us are not impaired.

Management fee

Pursuant to the investment advisory and management agreement, we pay AIM a fee for investment advisory and management services consisting of two components—a base management fee and an incentive fee. For the fiscal years ended March 31, 2008, 2007 and 2006, AIM received $59.9 million, $40.6 million and $23.4 million, respectively, in base investment advisory and management fees and $46.4 million, $36.6 million and $22.3 million, respectively, in performance-based net investment income incentive fees from us. At March 31, 2008, we had also accrued $0 for a net realized capital gains based incentive fee. The amount actually payable by us will be determined as of the end of the calendar year. For the calendar years 2007, 2006 and 2005, we have paid $5,304, $0 and $0, respectively, in net realized capital gain based incentive fees to AIM.

The base management fee is calculated at an annual rate of 2.00% of our average gross assets. The base management fee is payable quarterly in arrears. The base management fee is calculated based on the average value of our gross assets at the end of the two most recently completed calendar quarters, and appropriately adjusted for any share issuances or repurchases during the current calendar quarter. Base management fees for any partial month or quarter are appropriately pro rated.

The incentive fee has two parts, as follows: one part is calculated and payable quarterly in arrears based on our pre-incentive fee net investment income for the immediately preceding calendar quarter. For this purpose, pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that we receive from portfolio companies) accrued during the calendar quarter, minus our operating expenses for the quarter (including the base management fee, any expenses payable under the Administration Agreement, and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income does not include any realized capital gains computed net of all realized capital losses and unrealized capital depreciation. Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets at the end of the immediately preceding calendar quarter, is compared to the hurdle rate of 1.75% per quarter (7% annualized). Our net investment income used to calculate this part of the incentive fee is also included in the amount of our gross assets used to calculate the 2% base management fee. We pay AIM an incentive fee with respect to our pre-incentive fee net investment income in each calendar quarter as follows:

no incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the hurdle rate;

100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875% in any calendar quarter (8.75% annualized). We refer to this portion of our pre-incentive fee net investment income (which exceeds the hurdle rate but is less than 2.1875%) as the "catch-up." The "catch-up" provision is intended to provide our investment adviser with an incentive fee of 20% on all of our pre-incentive fee net investment income as if a hurdle rate did not apply when our net investment income exceeds 2.1875% in any calendar quarter; and

20% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter (8.75% annualized).

The following is a graphical representation of the calculation of the income-related portion of the incentive fee:

Quarterly Incentive Fee Based on Net Investment Income

Pre-incentive fee net investment income

(expressed as a percentage of the value of net assets)

Percentage of pre-incentive fee net investment income

allocated to income-related portion of incentive fee

These calculations are appropriately pro rated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter. You should be aware that a rise in the general level of interest rates can be expected to lead to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates would make it easier for us to meet or exceed the incentive fee hurdle rate and may result in a substantial increase of the amount of incentive fees payable to our investment adviser with respect to pre-incentive fee net investment income.

The second part of the incentive fee is determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Advisory and Management Agreement, as of the termination date) and will equal 20.0% of our realized capital gains for each calendar year computed net of all realized capital losses and unrealized capital depreciation and incorporating unrealized depreciation on a gross investment-by-investment basis at the end of such year. Capital gains with respect to any investment will equal the difference between the proceeds from the sale of such investment and the accreted or amortized cost basis of such investment.

Examples of Quarterly Incentive Fee Calculation

Example 1: Income Related Portion of Incentive Fee (*):

Alternative 1

Assumptions

Investment income (including interest, dividends, fees, etc.) = 1.25%

Hurdle rate(1) = 1.75%

Management fee(2) = 0.50%

Other expenses (legal, accounting, custodian, transfer agent, etc.)(3) = 0.20%

Pre-incentive fee net investment income

(investment income—(management fee + other expenses)) = 0.55%

Pre-incentive net investment income does not exceed hurdle rate, therefore there is no incentive fee.

Alternative 2

Assumptions

Investment income (including interest, dividends, fees, etc.) = 2.70%

Hurdle rate(1) = 1.75%

Management fee(2) = 0.50%

Other expenses (legal, accounting, custodian, transfer agent, etc.)(3) = 0.20%

Pre-incentive fee net investment income

(investment income—(management fee + other expenses)) = 2.00%

Incentive fee = 100% × pre-incentive fee net investment income, subject to the "catch-up"(4)

= 100% × (2.00% – 1.75%)

= 0.25%

Alternative 3

Assumptions

Investment income (including interest, dividends, fees, etc.) = 3.00%

Hurdle rate(1) = 1.75%

Management fee(2) = 0.50%

Other expenses (legal, accounting, custodian, transfer agent, etc.)(3) = 0.20%

Pre-incentive fee net investment income

(investment income—(management fee + other expenses)) = 2.30%

Incentive fee = 20% × pre-incentive fee net investment income, subject to "catch-up"(4)

Incentive fee = 100% × "catch-up" + (20% × (pre-incentive fee net investment income – 2.1875%))

Catch-up = 2.1875% – 1.75%

= 0.4375%

Incentive fee = (100% × 0.4375%) + (20% × (2.3% – 2.1875%))

= 0.4375% + (20% × 0.1125%)

= 0.4375% + 0.0225%

= 0.46%

__________

(*) The hypothetical amount of pre-incentive fee net investment income shown is based on a percentage of total net assets.

(1) Represents 7.0% annualized hurdle rate.

(2) Represents 2.0% annualized management fee.

(3) Excludes organizational and offering expenses.

(4) The "catch-up" provision is intended to provide our investment adviser with an incentive fee of 20% on all of our pre-incentive fee net investment income as if a hurdle rate did not apply when our net investment income exceeds 2.1875% in any calendar quarter.

Example 2: Capital Gains Portion of Incentive Fee:

Alternative 1:

Assumptions

Year 1: $20 million investment made in Company A ("Investment A"), and $30 million investment made in Company B ("Investment B")

Year 2: Investment A sold for $50 million and fair market value ("FMV") of Investment B determined to be $32 million

Year 3: FMV of Investment B determined to be $25 million

Year 4: Investment B sold for $31 million

The capital gains portion of the incentive fee would be:

Year 1: None

Year 2: Capital gains incentive fee of $6 million ($30 million realized capital gains on sale of Investment A multiplied by 20%)

Year 3: None

$5 million (20% multiplied by ($30 million cumulative capital gains less $5 million cumulative capital depreciation)) less $6 million (previous capital gains fee paid in Year 2)

Year 4: Capital gains incentive fee of $200,000

$6.2 million ($31 million cumulative realized capital gains multiplied by 20%) less $6 million (capital gains fee taken in Year 2)

Alternative 2

Assumptions

Year 1: $20 million investment made in Company A ("Investment A"), $30 million investment made in Company B ("Investment B") and $25 million investment made in Company C ("Investment C")

Year 2: Investment A sold for $50 million, FMV of Investment B determined to be $25 million and FMV of Investment C determined to be $25 million

Year 3: FMV of Investment B determined to be $27 million and Investment C sold for $30 million

Year 4: FMV of Investment B determined to be $35 million

Year 5: Investment B sold for $20 million

The capital gains incentive fee, if any, would be:

Year 1: None

Year 2: $5 million capital gains incentive fee

20% multiplied by $25 million ($30 million realized capital gains on Investment A less unrealized capital depreciation on Investment B)

Year 3: $1.4 million capital gains incentive fee(1)

$6.4 million (20% multiplied by $32 million ($35 million cumulative realized capital gains less $3 million unrealized capital depreciation)) less $5 million capital gains fee received in Year 2

Year 4: None

Year 5: None

$5 million (20% multiplied by $25 million (cumulative realized capital gains of $35 million less realized capital losses of $10 million)) less $6.4 million cumulative capital gains fee paid in Year 2 and Year 3"

____________

(1) As illustrated in Year 3 of Alternative 1 above, if Apollo Investment were to be wound up on a date other than December 31st of any year, Apollo Investment may have paid aggregate capital gain incentive fees that are more than the amount of such fees that would be payable if Apollo Investment had been wound up on December 31st of such year.

Payment of our expenses

All investment professionals of the investment adviser and their respective staffs when and to the extent engaged in providing investment advisory and management services, and the compensation and routine overhead expenses of such personnel allocable to such services, are provided and paid for by AIM. We bear all other costs and expenses of our operations and transactions, including those relating to: calculation of our net asset value (including the cost and expenses of any independent valuation firm); expenses incurred by AIM payable to third parties, including agents, consultants or other advisors, in monitoring our financial and legal affairs and in monitoring our investments and performing due diligence on our prospective portfolio companies; interest payable on debt, if any, incurred to finance our investments; offerings of our common stock and other securities; investment advisory and management fees; fees payable to third parties, including agents, consultants or other advisors, relating to, or associated with, evaluating and making investments; transfer agent and custodial fees; registration fees; listing fees; taxes; independent directors' fees and expenses; costs of preparing and filing reports or other documents of the SEC; the costs of any reports, proxy statements or other notices to stockholders, including printing costs; our allocable portion of the fidelity bond, directors' and officers'/errors and omissions liability insurance, and any other insurance premiums; direct costs and expenses of administration, including auditor and legal costs; and all other expenses incurred by us or Apollo Administration in connection with administering our business, such as our allocable portion of overhead under the administration agreement, including rent and our allocable portion of the cost of our chief compliance officer and chief financial officer and their respective staffs.

Duration and termination

The continuation of our investment advisory and management agreement was approved by our board of directors on March 24, 2008. Unless terminated earlier as described below, it will remain in effect from year to year if approved annually by our board of directors or by the affirmative vote of the holders of a majority of our outstanding voting securities, including, in either case, approval by a majority of our directors who are not interested persons. The investment advisory and management agreement will automatically terminate in the event of its assignment. Either party may terminate the investment advisory and management agreement without penalty upon not more than 60 days' written notice to the other party. See "Risk Factors—Risks relating to our business and

structure—We are dependent upon AIM's key personnel for our future success and upon their access to Apollo's investment professionals and partners."

Indemnification

The investment advisory and management agreement provides that, absent willful misfeasance, bad faith or gross negligence in the performance of its duties or reckless disregard of its duties and obligations, AIM and its officers, managers, partners, agents, employees, controlling persons, members and any other person or entity affiliated with it are entitled to indemnification from Apollo Investment for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of AIM's services under the investment advisory and management agreement or otherwise as an investment adviser of Apollo Investment.

Organization of the investment adviser

AIM is a Delaware limited partnership that is registered as an investment adviser under the Advisers Act. The principal executive offices of AIM are at 9 West 57th Street, New York, NY 10019.

Portfolio Manager

Patrick Dalton is primarily responsible for day-to-day management of our investment portfolio. He is an employee of our investment adviser and receives a compensation package from it that includes a base salary and variable incentive compensation based primarily on our performance. The dollar range of equity securities purchased and beneficially owned by Mr. Dalton in Apollo Investment is $50,001 - $100,000.

Board Approval of the Investment Advisory and Management Agreement

At a meeting of our board of directors held on March 24, 2008, the board, including our directors who are not "interested persons" as defined in the 1940 Act, voted to approve the continuation of the investment advisory and management agreement between us and AIM for another annual period in accordance with the requirements of the 1940 Act. Our independent directors had the opportunity to consult in executive session with their counsel regarding the approval of such agreement. In reaching a decision to approve the continuation of the investment advisory and management agreement, our board of directors reviewed a significant amount of information and considered, among other things:

the nature, extent and quality of the advisory and other services provided and to be provided to us by the investment adviser;

the investment performance of us and our investment adviser;

the reasonableness of the fee payable by us to the investment adviser in light of comparative performance; expense and advisory fee information, costs of the services provided, and profits realized and benefits derived or to be derived by the investment adviser from its relationship with us;

the potential for economies of scale to be realized by the investment adviser in managing our assets and the extent to which material economies of scale may be shared with us; and

various other matters.

In approving the continuation of the investment advisory and management agreement, our board of directors, including the directors who are not "interested persons," made the following determinations:

Nature, Extent and Quality of Services. Our board of directors received and considered information regarding the nature, extent and quality of the investment selection process employed by the investment adviser. In addition, our board of directors received and considered other information regarding the administrative and other services rendered to us by affiliates of the investment adviser and noted information received at regular meetings throughout the year related to the services rendered by the investment adviser in its management of our affairs. Our board of directors also considered the backgrounds and responsibilities of the investment adviser's senior personnel and their qualifications and experience in connection with the types of investments made by us. The board noted recent additions to the investment adviser's personnel and the investment adviser's commitment to providing us with qualified investment and compliance personnel. Our board also considered the financial resources available to the investment adviser. Our board of directors determined that the nature, extent and quality of the services provided by the investment adviser are adequate and appropriate.

Investment Performance. Our board of directors reviewed the long-term and short-term investment performance of Apollo Investment and the investment adviser, as well as comparative data with respect to the long-term and short-term investment performance of other externally-managed business development companies. Our board of directors concluded that the investment adviser was delivering results consistent with our investment objective and that our investment performance was satisfactory when compared to comparable business development companies.

The reasonableness of the fee payable by us to the investment adviser. Our board of directors considered comparative data based on publicly available information and information provided by a third party retained to provide comparative data on other business development companies with respect to services rendered and the advisory fees (including the management fees and incentive fees) of other business development companies as well as our operating expenses and expense ratio compared to other business development companies, including business development companies with similar investment objectives. Based upon its review, the board of directors concluded that the fees payable under the investment advisory and management agreement are reasonable compared to other business development companies and in light of the services provided by the investment adviser and the costs to the investment adviser of providing such services. In addition, our board of directors concluded that our expenses as a percentage of net assets attributable to common stock are reasonable as compared to other business development companies.

Economies of Scale. Our board of directors considered information about the potential of the investment adviser to realize economies of scale in managing our assets, and determined that at this time there were no economies of scale to be realized by the investment adviser and that, to the extent any such material economies of scale were to be realized by the investment adviser, our board of directors would seek to have such economies of scale shared with us.

Based on the information reviewed and the discussions above, our directors (including those directors who are not "interested persons") concluded that the terms of the investment advisory and management agreement, including the fee rates thereunder, are fair and reasonable in relation to the services provided and approved the continuation of the investment advisory and management agreement with the investment adviser as being in the best interests of Apollo Investment and its stockholders.

In view of the wide variety of factors that our board of directors considered in connection with its evaluation of the investment advisory and management agreement, it is not practical to quantify, rank or otherwise assign relative weights to the specific factors our board considered in reaching its decision. Our board of directors did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to the ultimate determination of our board of directors. Rather, our board of directors based its approval on the totality of information presented to, and reviewed by, it. In considering the factors discussed above, individual directors may have given different weights to different factors.

ADMINISTRATION AGREEMENT

Pursuant to a separate administration agreement, AIA furnishes us with office facilities, equipment and clerical, bookkeeping and record keeping services at such facilities. Under the administration agreement, AIA also performs, or oversees the performance of, our required administrative services, which include, among other things, being responsible for the financial records that we are required to maintain and preparing reports to our stockholders and reports filed with the SEC. In addition, AIA assists us in determining and publishing our net asset value, oversees the preparation and filing of our tax returns and the printing and dissemination of reports to our stockholders, and generally oversees the payment of our expenses and the performance of administrative and professional services rendered to us by others. Payments under the administration agreement are equal to an amount based upon our allocable portion of AIA's overhead in performing its obligations under the administration agreement, including rent and our allocable portion of the cost of our chief compliance officer and chief financial officer and their respective staffs. Under the administration agreement, AIA also provides on our behalf managerial assistance to those portfolio companies to which we are required to provide such assistance. Either party may terminate the administration agreement without penalty upon 60 days' written notice to the other party.

For the fiscal years ended March 31, 2008, 2007 and 2006, AIA was reimbursed $3,162, $2,237 and $1,017, respectively, from Apollo Investment on the $3,450, $2,437 and $1,470, respectively, of expenses accrued under the administration agreement.

Indemnification

The administration agreement provides that, absent willful misfeasance, bad faith or gross negligence in the performance of its duties or reckless disregard of its duties and obligations, AIA and its officers, managers, partners, agents, employees, controlling persons, members and any other person or entity affiliated with it are entitled to indemnification from us for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of AIA's services under the administration agreement or otherwise as administrator for us.

LICENSE AGREEMENT

We have entered into a license agreement with Apollo pursuant to which Apollo has agreed to grant us a non-exclusive, royalty-free license to use the name "Apollo." Under this agreement, we will have a right to use the Apollo name, for so long as AIM or one of its affiliates remains our investment adviser. Other than with respect to this limited license, we will have no legal right to the "Apollo" name. This license agreement will remain in effect for so long as the investment advisory and management agreement with our investment adviser is in effect.

CERTAIN RELATIONSHIPS

We have entered into the investment advisory and management agreement with AIM. Our senior management and our chairman of the board of directors have ownership and financial interests in AIM. Our senior management also serve as principals of other investment managers affiliated with AIM that may in the future manage investment funds with investment objectives similar to ours. In addition, our executive officers and directors and the partners of our investment adviser, AIM, serve or may serve as officers, directors or principals of entities that operate in the same or related line of business as we do or of investment funds managed by our affiliates. Accordingly, we may not be given the opportunity to participate in certain investments made by investment funds managed by advisers affiliated with AIM. However, our investment adviser and other members of Apollo intend to allocate investment opportunities in a fair and equitable manner consistent with our investment objective and strategies so that we are not disadvantaged in relation to any other client. See "Risk Factors—Risks relating to our business and structure—There are significant potential conflicts of interest which could impact our investment returns."

We have entered into a license agreement with Apollo, pursuant to which Apollo has agreed to grant us a non-exclusive, royalty-free license to use the name "Apollo." In addition, pursuant to the terms of the administration agreement, AIA provides us with the office facilities and administrative services necessary to conduct our day-to-day operations. AIM is the sole member of and controls AIA.

We have in the past and expect in the future to co-invest on a concurrent basis with other affiliates, subject to compliance with existing regulatory guidance, applicable regulations and our allocation procedures. Certain types of negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance that any such order will be obtained.

CONTROL PERSONS AND PRINCIPAL STOCKHOLDERS

As of August 31, 2008, there were no persons that owned 25% or more of our outstanding voting securities, and no person would be deemed to control us, as such term is defined in the 1940 Act.

The following table sets forth, as of August 31, 2008 , certain ownership information with respect to our common stock for those persons who directly or indirectly owned, controlled or held with the power to vote, 5% or more of our outstanding common stock as of that date and all officers and directors, as a group.

PORTFOLIO COMPANIES

The following is a listing of each portfolio company or its affiliate, together referred to as portfolio companies, in which we had an investment at June 30, 2008. A percentage shown for a class of investment securities held by us represents the percentage of the class owned and does not necessarily represent voting ownership. A percentage shown for equity securities, other than warrants or options, represents the actual percentage

of the class of security held on a fully dilued basis. A percentage shown for warrants and options held represents the percentage of a class of security we may own assuming we exercise our warrants or options after dilution. See the financial statements to this base prospectus and any accompanying prospectus supplement for information regarding the fair value of these securities and for the general terms of any loans to the portfolio companies.

The portfolio companies are presented in three categories: "companies more than 25% owned," which represent portfolio companies with respect to which we directly or indirectly own more than 25% of the outstanding voting securities of such portfolio company and, therefore, are presumed to be controlled by us under the 1940 Act; "companies owned 5% to 25%," which represent portfolio companies with respect to which we directly or indirectly own 5% to 25% of the outstanding voting securities of such portfolio company or with respect to which we hold one or more seats on the portfolio company's board of directors and, therefore, are deemed to be an affiliated person under the 1940 Act; and "companies less than 5% owned," which represent portfolio companies with respect to which we directly or indirectly own less than 5% of the outstanding voting securities of such portfolio company and with respect to which we have no other affiliations. We make available significant managerial assistance to our portfolio companies. We generally request and may receive rights to observe the meetings of our portfolio companies' board of directors.

DETERMINATION OF NET ASSET VALUE

In calculating the value of our total assets, we value investments for which market quotations are readily available at such market quotations if they are deemed to represent fair value. Debt and equity securities that are not publicly traded or whose market price is not readily available or whose market quotations are not deemed to represent fair value are valued at fair value as determined in good faith by or under the direction of our board of directors. Market quotations may be deemed not to represent fair value in certain circumstances where AIM reasonably believes that facts and circumstances applicable to an issuer, a seller or purchaser or the market for a particular security causes current market quotes to not reflect the fair value of the security. Examples of these events could include cases in which material events are announced after the close of the market on which a security is primarily traded, when a security trades infrequently causing a quoted purchase or sale price to become stale or in the event of a "fire sale" by a distressed seller.

As a general rule, we do not value our private unquoted loans or debt securities above cost, but loans and debt securities are subject to fair value write-downs when the asset is considered impaired. With respect to private equity securities, each investment is valued considering comparisons of financial ratios of the portfolio companies that issued such private equity securities to peer companies that are public among other factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we use the pricing indicated by the external event to corroborate our private equity valuation. Because we believe that there is not a readily available market value for a significant portion of the investments in our portfolio, we value substantially all of our portfolio investments at fair value as determined in good faith by or under the direction of our board of directors pursuant to a valuation policy and a consistently applied valuation process utilizing the input of our investment adviser, independent valuation firms and the audit committee. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may differ significantly from the values that would have been used had a ready market existed for such investments, and the differences could be material.

(2) preliminary valuation conclusions are then documented and discussed with senior management of our investment adviser;

In following these approaches, the types of factors that are taken into account in fair value pricing investments include, as relevant, but are not limited to: available current market data, including relevant and applicable market trading and transaction comparables; applicable market yields and multiples; security covenants; call protection provisions; information rights; the nature and realizable value of any collateral; the portfolio company’s ability to make payments, its earnings and discounted cash flows and the markets in which it does business; comparisons of financial ratios of peer companies that are public; M&A comparables; and the principal market and enterprise values.

Determination of fair values involves subjective judgments and estimates not susceptible to substantiation by auditing procedures. Accordingly, under current auditing standards, the notes to our financial statements refer to the uncertainty with respect to the possible effect of such valuations, and any change in such valuations, on our financial statements.

DIVIDEND REINVESTMENT PLAN

We have adopted a dividend reinvestment plan that provides for reinvestment of our dividend distributions on behalf of our stockholders, unless a stockholder elects to receive cash as provided below. As a result, if our board of directors authorizes, and we declare, a cash dividend, then our stockholders who have not "opted out" of our dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of our common stock, rather than receiving the cash dividends.

No action is required on the part of a registered stockholder to have such stockholder's cash dividend reinvested in shares of our common stock. A registered stockholder may elect to receive an entire dividend in cash by notifying American Stock Transfer and Trust Company, the plan administrator and our transfer agent and registrar, in writing so that such notice is received by the plan administrator not less than 10 days prior to the record date for dividends to stockholders. The plan administrator will set up an account for shares acquired through the plan for each stockholder who has not elected to receive dividends in cash and hold such shares in non-certificated form. Upon request by a stockholder participating in the plan, received in writing not less than 10 days prior to the record date, the plan administrator will, instead of crediting shares to the participant's account, issue a certificate registered in the participant's name for the number of whole shares of our common stock and a check for any fractional share.

Those stockholders whose shares are held by a broker or other financial intermediary may receive dividends in cash by notifying their broker or other financial intermediary of their election.

We intend to use primarily newly-issued shares to implement the plan, whether our shares are trading at a premium or at a discount to net asset value. However, we reserve the right to purchase shares in the open market in connection with our implementation of the plan. The number of shares to be issued to a stockholder is determined by dividing the total dollar amount of the dividend payable to such stockholder by the market price per share of our common stock at the close of regular trading on The Nasdaq Global Select Market on the valuation date for such dividend. Market price per share on that date will be the closing price for such shares on The Nasdaq Global Select Market or, if no sale is reported for such day, at the average of the reported bid and asked prices. The number of shares of our common stock to be outstanding after giving effect to payment of the dividend cannot be established until the value per share at which additional shares will be issued has been determined and elections of our stockholders have been tabulated.

There will be no brokerage charges or other charges to stockholders who participate in the plan. The plan administrator's fees under the plan will be paid by us. If a participant elects by written notice to the plan administrator to have the plan administrator sell part or all of the shares held by the plan administrator in the participant's account and remit the proceeds to the participant, the plan administrator is authorized to deduct a $15 transaction fee plus a 10¢ per share brokerage commission from the proceeds.

Stockholders who receive dividends in the form of stock are subject to the same federal, state and local tax consequences as are stockholders who elect to receive their dividends in cash. A stockholder's basis for determining gain or loss upon the sale of stock received in a dividend from us will be equal to the total dollar amount of the dividend payable to the stockholder. Any stock received in a dividend will have a new holding period for tax purposes commencing on the day following the day on which the shares are credited to the U.S. stockholder's account.

Participants may terminate their accounts under the plan by notifying the plan administrator via its website at www.amstock.com, by filling out the transaction request form located at the bottom of their statement and sending it to the plan administrator at P.O. Box 922, Wall Street Station, NY, NY 10269-0560 or by calling the plan administrator's Interactive Voice Response System at 1-888-777-0324.

The plan may be terminated by us upon notice in writing mailed to each participant at least 30 days prior to any record date for the payment of any dividend by us. All correspondence, including requests for additional information, concerning the plan should be directed to the plan administrator by mail at American Stock Transfer and Trust Company, 59 Maiden Lane, New York, NY 10007 or by telephone at (718) 921-8200.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a general summary of the material U.S. federal income tax considerations applicable to us and to an investment in shares of our common stock. This summary does not purport to be a complete description of the income tax considerations applicable to such an investment. For example, we have not described tax consequences that we assume to be generally known by investors or certain considerations that may be relevant to certain types of holders subject to special treatment under U.S. federal income tax laws, including stockholders subject to the alternative minimum tax, tax-exempt organizations, insurance companies, dealers in securities, pension plans and trusts, and financial institutions. This summary assumes that investors hold our common stock as capital assets (generally property held for investment). The discussion is based upon the Code, Treasury regulations, and administrative and judicial interpretations, each as of the date of this prospectus and all of which are subject to change, possibly retroactively, which could affect the continuing validity of this discussion. We have not sought and will not seek any ruling from the Internal Revenue Service (the "IRS") regarding this offering. This summary does not discuss any aspects of U.S. estate or gift tax or foreign, state or local tax. It does not discuss the special treatment under U.S. federal income tax laws that could result if we invested in tax-exempt securities or certain other investment assets.

This summary does not discuss the consequences of an investment in shares of our preferred stock, debt securities or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities. The tax consequences of such an investment will be discussed in a relevant prospectus supplement.

A "U.S. stockholder" is a beneficial owner of shares of our common stock that is for U.S. federal income tax purposes:

a citizen or individual resident of the United States;

a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia; or

a trust or an estate, the income of which is subject to U.S. federal income taxation regardless of its source.

A "Non-U.S. stockholder" is a beneficial owner of shares of our common stock that is neither a U.S. stockholder nor a partnership for U.S. federal income tax purposes.

If a partnership (including an entity treated as a partnership for U.S. federal income tax purposes) holds shares of our common stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A prospective stockholder that is a partner of a partnership holding shares of our common stock should consult its tax advisors with respect to the purchase, ownership and disposition of shares of our common stock.

Tax matters are very complicated, and the tax consequences to an investor of an investment in our shares will depend on the facts of his, her or its particular situation. We encourage investors to consult their own tax advisors regarding the specific consequences of such an investment, including tax reporting requirements, the applicability of federal, state, local and foreign tax laws, eligibility for the benefits of any applicable tax treaty and the effect of any possible changes in the tax laws.

Election to be Taxed as a RIC

As a BDC, we have elected to be treated as a RIC under Subchapter M of the Code. As a RIC, we generally will not have to pay corporate-level federal income taxes on any ordinary income or capital gains that we distribute to our stockholders as dividends. To qualify as a RIC, we must, among other things, meet certain source-of-income and asset diversification requirements (as described below). In addition, to obtain RIC tax treatment we must distribute to our stockholders, for each taxable year, at least 90% of our "investment company taxable income (determined without regard to the dividends paid deduction)," which is generally our ordinary income plus the excess of realized net short-term capital gains over realized net long-term capital losses (the "Annual Distribution Requirement").

Taxation as a RIC

If we qualify as a RIC and satisfy the Annual Distribution Requirement, then we will not be subject to federal income tax on the portion of our investment company taxable income and net capital gain (i.e., realized net long-term capital gains in excess of realized net short-term capital losses) we distribute to stockholders with respect to that year. We will be subject to U.S. federal income tax at the regular corporate rates on any income or capital gain not distributed (or deemed distributed) to our stockholders.

We will be subject to a 4% nondeductible federal excise tax on certain undistributed income of RICs unless we distribute in a timely manner an amount at least equal to the sum of (1) 98% of our ordinary income for each calendar year, (2) 98% of our capital gain net income for the one-year period ending October 31 in that calendar year and (3) any income realized, but not distributed, in preceding years (the "Excise Tax Avoidance Requirement"). We will not be subject to excise taxes on amounts on which we are required to pay corporate income taxes (such as retained net capital gains).

In order to qualify as a RIC for federal income tax purposes, we must, among other things:

qualify and have in effect an election to be treated as a BDC under the 1940 Act at all times during each taxable year;

derive in each taxable year at least 90% of our gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale of stock or other securities, or other income derived with respect to our business of investing in such stock or securities (the "90% Income Test"),

and net income derived from an interest in a "qualified publicly traded partnership" (as defined in the Code) (the "90% Income Test");

diversify our holdings so that at the end of each quarter of the taxable year:

at least 50% of the value of our assets consists of cash, cash equivalents, U.S. Government securities, securities of other RICs, and other securities if such other securities of any one issuer do not represent more than 5% of the value of our assets or more than 10% of the outstanding voting securities of the issuer; and

no more than 25% of the value of our assets is invested in the securities, other than U.S. Government securities or securities of other RICs, of one issuer or of two or more issuers that are controlled, as determined under applicable tax rules, by us and that are engaged in the same or similar or related trades or businesses or in securities of one or more qualified publicly traded partnerships (the "Diversification Tests").

We may be required to recognize taxable income in circumstances in which we do not receive cash. For example, if we hold debt obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments with payment-in-kind interest or, in certain cases, increasing interest rates or issued with warrants), we must include in income each year a portion of the original issue discount that accrues over the life of the obligation, regardless of whether cash representing such income is received by us in the same taxable year. Because any original issue discount accrued will be included in our investment company taxable income for the year of accrual, we may be required to make a distribution to our stockholders in order to satisfy the Annual Distribution Requirement, even though we will not have received any corresponding cash amount.

Gain or loss realized by us from the sale or exchange of warrants acquired by us as well as any loss attributable to the lapse of such warrants generally will be treated as capital gain or loss. Such gain or loss generally will be long-term or short-term, depending on how long we held a particular warrant.

Although we do not presently expect to do so, we are authorized to borrow funds and to sell assets in order to satisfy the Annual Distribution Requirement. However, under the 1940 Act, we are not permitted to make distributions to our stockholders while our debt obligations and other senior securities are outstanding unless certain "asset coverage" tests are met. See "Regulation—Senior Securities." Moreover, our ability to dispose of assets to meet the Annual Distribution Requirements may be limited by (1) the illiquid nature of our portfolio and/or (2) other requirements relating to our status as a RIC, including the Diversification Tests. If we dispose of assets in order to meet the Annual Distribution Requirement or the Excise Tax Avoidance Requirement, we may make such dispositions at times that, from an investment standpoint, are not advantageous.

If we fail to satisfy the Annual Distribution Requirement or otherwise fail to qualify as a RIC in any taxable year, we will be subject to tax in that year on all of our taxable income, regardless of whether we make any distributions to our stockholders. In that case, all of our income would be subject to corporate-level federal income tax, reducing the amount available to be distributed to our stockholders. In contrast, assuming we qualify as a RIC, our corporate-level federal income tax should be substantially reduced or eliminated. See "Election to be Taxed as a RIC" above.

Certain of our investment practices may be subject to special and complex federal income tax provisions that may, among other things, (i) treat dividends that would otherwise constitute qualified dividend income as non-qualified dividend income, (ii) treat dividends that would otherwise be eligible for the corporate dividends-received deduction as ineligible for such treatment, (iii) disallow, suspend or otherwise limit the allowance of certain losses or deductions, (iv) convert lower-taxed long-term capital gain into higher-taxed short-term capital gain or ordinary income, (v) convert an ordinary loss or a deduction into a capital loss (the deductibility of which is more limited), (vi) cause us to recognize income or gain without a corresponding receipt of cash, (vii) adversely affect the time as to when a purchase or sale of stock or securities is deemed to occur, (viii) adversely alter the characterization of certain complex financial transactions and (ix) produce income that will not be qualifying income for purposes of the 90% Income Test. We intend to monitor our transactions and may make certain tax elections to mitigate the effect of these provisions and prevent our disqualification as a RIC.

The remainder of this discussion assumes that we qualify as a RIC and have satisfied the Annual Distribution Requirement.

Taxation of U.S. Stockholders

Distributions by us generally are taxable to U.S. stockholders as ordinary income or capital gains. Distributions of our "investment company taxable income" (which is, generally, our ordinary income plus realized net short-term capital gains in excess of realized net long-term capital losses) will be taxable as ordinary income to U.S. stockholders to the extent of our current or accumulated earnings and profits, whether paid in cash or reinvested in additional common stock through our dividend reinvestment plan. To the extent such distributions paid by us to non-corporate stockholders (including individuals) are attributable to dividends from U.S. corporations and certain qualified foreign corporations, such distributions generally will be eligible for a maximum federal income tax rate of 15% for taxable years beginning before 2011. In this regard, it is anticipated that distributions paid by us will generally not be attributable to dividends and, therefore, generally will not qualify for the 15% maximum rate. Distributions of our net capital gains (which is generally our realized net long-term capital gains in excess of realized net short-term capital losses) properly designated by us as "capital gain dividends" will be taxable to a U.S. stockholder as long-term capital gains (currently at a maximum rate of 15% in the case of individuals, trusts or estates), regardless of the U.S. stockholder's holding period for his, her or its common stock and regardless of whether paid in cash or reinvested in additional common stock. Distributions in excess of our earnings and profits first will reduce a U.S. stockholder's adjusted tax basis in such stockholder's common stock and, after the adjusted tax basis is reduced to zero, will constitute capital gains to such U.S. stockholder.

Although we currently intend to distribute any net capital gain at least annually, we may in the future decide to retain some or all of our net capital gain, but designate the retained amount as a "deemed distribution." In that case, among other consequences, we will pay tax on the retained amount, each U.S. stockholder will be required to include his, her or its share of the deemed distribution in income as if it had been actually distributed to the U.S. stockholder, and the U.S. stockholder will be entitled to claim a credit equal to his, her or its allocable share of the tax paid thereon by us. The amount of the deemed distribution net of such tax will be added to the U.S. stockholder's tax basis for his, her or its common stock. Since we expect to pay tax on any retained capital gains at our regular corporate tax rate and since that rate is in excess of the maximum rate currently payable by individuals on long-term capital gains, the amount of tax that individual stockholders will be treated as having paid and for which they will receive a credit will exceed the tax they owe on the retained net capital gain. Such excess generally may be claimed as a credit against the U.S. stockholder's other federal income tax obligations or may be refunded to the extent it exceeds a stockholder's liability for federal income tax. A stockholder that is not subject to federal income tax or otherwise required to file a federal income tax return would be required to file a federal income tax return on the appropriate form in order to claim a refund for the taxes we paid. In order to utilize the deemed distribution approach, we must provide written notice to our stockholders prior to the expiration of 60 days after the close of the relevant taxable year. We cannot treat any of our investment company taxable income as a "deemed distribution."

For purposes of determining (1) whether the Annual Distribution Requirement is satisfied for any year and (2) the amount of capital gain dividends paid for that year, we may, under certain circumstances, elect to treat a dividend that is paid during the following taxable year as if it had been paid during the taxable year in question. If we make such an election, the U.S. stockholders will still be treated as receiving the dividend in the taxable year in which the distribution is made. However, any dividend declared by us in October, November or December of any calendar year, payable to stockholders of record on a specified date in such a month and actually paid during January of the following year, will be treated as if it had been received by our U.S. stockholders on December 31 of the year in which the dividend was declared.

If an investor purchases shares of our common stock shortly before the record date of a distribution, the price of the shares will include the value of the distribution and the investor will be subject to tax on the distribution even though it represents a return of his, her or its investment.

A U.S. stockholder generally will recognize taxable gain or loss if the stockholder sells or otherwise disposes of his, her or its shares of our common stock. Any gain arising from such sale or disposition generally will be treated as long-term capital gain or loss if the stockholder has held his, her or its shares for more than one year. Otherwise, it would be classified as short-term capital gain or loss. However, any capital loss arising from the sale or disposition of shares of our common stock held for six months or less will be treated as long-term capital loss to the

extent of the amount of capital gain dividends received, or undistributed capital gain deemed received, with respect to such shares. In addition, all or a portion of any loss recognized upon a disposition of shares of our common stock may be disallowed if other shares of our common stock are purchased (whether through reinvestment of distributions or otherwise) within 30 days before or after the disposition.

In general, individual and other non-corporate U.S. taxable stockholders currently are subject to a maximum federal income tax rate of 15% on their net capital gain, i.e., the excess of realized net long-term capital gain over realized net short-term capital loss for a taxable year, including any long-term capital gain derived from an investment in our shares. Such rate is lower than the maximum rate on ordinary income currently applicable to individuals. Corporate U.S. stockholders currently are subject to federal income tax on net capital gain at the maximum 35% rate also applied to ordinary income. Non-corporate stockholders with net capital losses for a year (i.e., capital losses in excess of capital gains) generally may deduct up to $3,000 of such losses against their ordinary income each year; any net capital losses of a non-corporate stockholder in excess of $3,000 generally may be carried forward and used in subsequent years as provided in the Code. Corporate stockholders generally may not deduct any net capital losses against ordinary income for a year, but may carry back such losses for three years or carry forward such losses for five years.

We will send to each of our U.S. stockholders, as promptly as possible after the end of each calendar year, a notice detailing, on a per share and per distribution basis, the amounts includible in such U.S. stockholder's taxable income for such year as ordinary income and as long-term capital gain. In addition, the federal tax status of each year's distributions generally will be reported to the IRS (including the amount of dividends, if any, eligible for the 15% maximum rate). Distributions may also be subject to additional state, local and foreign taxes depending on a U.S. stockholder's particular situation. Dividends distributed by us generally will not be eligible for the dividends-received deduction or the 15% maximum rate applicable to qualifying dividends.

We may be required to withhold federal income tax ("backup withholding") currently at a rate of 28% from all taxable distributions to any non-corporate U.S. stockholder (1) who fails to furnish us with a correct taxpayer identification number or a certificate that such stockholder is exempt from backup withholding or (2) with respect to whom the IRS notifies us that such stockholder has failed to report properly certain interest and dividend income to the IRS and to respond to notices to that effect. An individual's taxpayer identification number is his or her social security number. Any amount withheld under backup withholding is allowed as a credit against the U.S. stockholder's federal income tax liability and may entitle such stockholder to a refund, provided that proper information is timely provided to the IRS.

Taxation of Non-U.S. Stockholders

Whether an investment in the shares is appropriate for a Non-U.S. stockholder will depend upon that person's particular circumstances. An investment in the shares by a Non-U.S. stockholder may have adverse tax consequences. Non-U.S. stockholders should consult their tax advisors before investing in our common stock.

Distributions of our "investment company taxable income" to Non-U.S. stockholders, subject to the discussion below, will be subject to withholding of federal tax at a 30% rate (or lower rate provided by an applicable treaty) to the extent of our current and accumulated earnings and profits unless the distributions are effectively connected with a U.S. trade or business of the Non-U.S. stockholder, and, if an income tax treaty applies, attributable to a permanent establishment in the United States, in which case the distributions will be subject to federal income tax at the rates applicable to U.S. stockholders, and we will not be required to withhold federal tax if the Non-U.S. stockholder complies with applicable certification and disclosure requirements. Special certification requirements apply to a Non-U.S. stockholder that is a foreign partnership or a foreign trust, and such entities are urged to consult their own tax advisors.

Actual or deemed distributions of our net capital gains to a Non-U.S. stockholder and gains realized by a Non-U.S. stockholder upon the sale of our common stock, will not be subject to federal withholding tax and generally will not be subject to federal income tax unless the distributions or gains, as the case may be, are

effectively connected with a U.S. trade or business of the Non-U.S. stockholder and, if an income tax treaty applies, are attributable to a permanent establishment maintained by the Non-U.S. stockholder in the United States.

If we distribute our net capital gains in the form of deemed rather than actual distributions (which we may do in the future), a Non-U.S. stockholder will be entitled to a federal income tax credit or tax refund equal to the stockholder's allocable share of the tax we pay on the capital gains deemed to have been distributed. In order to obtain the refund, the Non-U.S. stockholder must obtain a U.S. taxpayer identification number and file a federal income tax return even if the Non-U.S. stockholder would not otherwise be required to obtain a U.S. taxpayer identification number or file a federal income tax return. For a corporate Non-U.S. stockholder, distributions (both actual and deemed), and gains realized upon the sale of our common stock that are effectively connected with a U.S. trade or business may, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate (or at a lower rate if provided for by an applicable tax treaty). Accordingly, investment in the shares may not be appropriate for certain Non-U.S. stockholders.

A Non-U.S. stockholder who is a non-resident alien individual, and who is otherwise subject to withholding of federal income tax, may be subject to information reporting and backup withholding of federal income tax on dividends unless the Non-U.S. stockholder provides us or the dividend paying agent with an IRS Form W-8BEN (or an acceptable substitute form) or otherwise meets documentary evidence requirements for establishing that it is a Non-U.S. stockholder or otherwise establishes an exemption from backup withholding.

Non-U.S. persons should consult their own tax advisors with respect to the U.S. federal income tax and withholding tax, and state, local and foreign tax consequences of an investment in the shares.

Failure to Qualify as a RIC

If we were unable to qualify for treatment as a RIC, we would be subject to federal income tax on all of our taxable income at regular corporate rates. We would not be able to deduct distributions to stockholders, nor would they be required to be made. Distributions would generally be taxable to our individual and other, non-corporate taxable stockholders as ordinary dividend income eligible for the 15% maximum rate for taxable years beginning before 2011 to the extent of our current and accumulated earnings and profits. Subject to certain limitations under the Code, corporate distributees would be eligible for the dividends-received deduction. Distributions in excess of our current and accumulated earnings and profits would be treated first as a return of capital to the extent of the stockholder's adjusted tax basis, and any remaining distributions would be treated as a capital gain. Moreover, if the BDC fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If the BDC fails to qualify as a RIC for a period of greater than two taxable years, the BDC may be required to recognize any net built-in gains with respect to certain of its assets ( i.e ., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the BDC had been liquidated) if it qualifies as a RIC in a subsequent year.

DESCRIPTION OF OUR CAPITAL STOCK

The following description is based on relevant portions of the Maryland General Corporation Law and on our charter and bylaws. This summary is not necessarily complete, and we refer you to the Maryland General Corporation Law and our charter and bylaws for a more detailed description of the provisions summarized below.

Capital Stock

At March 31, 2008 our authorized capital stock consists of 400,000,000 shares of stock, par value $0.001 per share, all of which is initially designated as common stock. Our common stock is quoted on The Nasdaq Global Select Market under the ticker symbol "AINV." There are no outstanding options or warrants to purchase our stock, and no stock has been authorized for issuance under any equity compensation plans. Under Maryland law, our stockholders generally are not personally liable for our debts or obligations. The last reported closing market price of our common stock on ______________, 2008 was $_______ per share. As of September 19, 2008, we had 103 stockholders of record.

Under our charter, our board of directors is authorized to classify and reclassify any unissued shares of stock into other classes or series of stock and authorize the issuance of shares of stock without obtaining stockholder approval. As permitted by the Maryland General Corporation Law, our charter provides that the board of directors, without any action by our stockholders, may amend the charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue.

The following table sets forth information of our capital stock as of March 31, 2008:

Title of Class of Securities	Amount Authorized	Amount Held by Registrant or for its Account	Amount Outstanding Exclusive of Amount held by Registrant or for its Account
Common stock, par value $0.001 per share	400,000,000	None	119,893 835 shares

Common stock

All shares of our common stock have equal rights as to earnings, assets, dividends and voting and, when they are issued, will be duly authorized, validly issued, fully paid and nonassessable. Distributions may be paid to the holders of our common stock if, as and when authorized by our board of directors and declared by us out of funds legally available therefor. Shares of our common stock have no preemptive, exchange, conversion or redemption rights and are freely transferable, except where their transfer is restricted by federal and state securities laws or by contract. In the event of a liquidation, dissolution or winding up of Apollo Investment, each share of our common stock would be entitled to share ratably in all of our assets that are legally available for distribution after we pay all debts and other liabilities and subject to any preferential rights of holders of our preferred stock, if any preferred stock is outstanding at such time. Each share of our common stock is entitled to one vote on all matters submitted to a vote of stockholders, including the election of directors. Except as provided with respect to any other class or series of stock, the holders of our common stock will possess exclusive voting power. There is no cumulative voting in the election of directors, which means that holders of a majority of the outstanding shares of common stock can elect all of our directors, and holders of less than a majority of such shares will be unable to elect any director.

Preferred stock

Our charter authorizes our board of directors to classify and reclassify any unissued shares of stock into other classes or series of stock, including preferred stock. Prior to issuance of shares of each class or series, the board of directors is required by Maryland law and by our charter to set the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Thus, the board of directors could authorize the issuance of shares of preferred stock with terms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of our common stock or otherwise be in their best interest. You should note, however, that any issuance of preferred stock must comply with the requirements of the 1940 Act. The 1940 Act requires, among other things, that (1) immediately after issuance and before any dividend or other distribution is made with respect to our common stock and before any purchase of common stock is made, such preferred stock together with all other senior securities must not exceed an amount equal to 50% of our total assets after such issuance and after deducting the amount of such dividend, distribution or purchase price, as the case may be, and (2) the holders of shares of preferred stock, if any are issued, must be entitled as a class to elect two directors at all times and to elect a majority of the directors if dividends on such preferred stock become in arrears by two years or more until the arrears are eliminated. Certain matters under the 1940 Act require the separate vote of the holders of any issued and outstanding preferred stock. For example, holders of preferred stock would vote separately from the holders of common stock on a proposal to cease operations as a BDC. We believe that the availability for issuance of preferred stock will provide us with increased flexibility in structuring future financings and acquisitions.

Limitation on Liability of Directors and Officers; Indemnification and Advance of Expenses

Maryland law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from (a) actual receipt of an improper benefit or profit in money, property or services or (b) active and deliberate dishonesty established by a final judgment as being material to the cause of action. Our charter contains such a provision which eliminates directors' and officers' liability to the maximum extent permitted by Maryland law, subject to the requirements of the 1940 Act.

Our charter authorizes us and our bylaws obligate us, to the maximum extent permitted by Maryland law and subject to the requirements of the 1940 Act, to indemnify any present or former director or officer or any individual who, while a director or officer and at our request, serves or has served another corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner or trustee, from and against any claim or liability to which that person may become subject or which that person may incur by reason of his or her status as a present or former director or officer and to pay or reimburse that person's reasonable expenses in advance of final disposition of a proceeding. The charter and bylaws also permit us to indemnify and advance expenses to any person who served a predecessor of us in any of the capacities described above and any of our employees or agents or any employees or agents of our predecessor. In accordance with the 1940 Act, we will not indemnify any person for any liability to which such person would be subject by reason of such person's willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

Maryland law requires a corporation (unless its charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made, or threatened to be made, a party by reason of his or her service in that capacity. Maryland law permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made, or threatened to be made, a party by reason of their service in those or other capacities unless it is established that (a) the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty, (b) the director or officer actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that a personal benefit was improperly received, unless in either case a court orders indemnification, and then only for expenses. In addition, Maryland law permits a corporation to advance reasonable expenses to a director or officer upon the corporation's receipt of (a) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation and (b) a written undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.

Provisions of the Maryland General Corporation Law and Our Charter and Bylaws

Provisions of the Maryland General Corporation Law and of our charter and bylaws could deter takeover attempts and have an adverse impact on the price of our common stock. The Maryland General Corporation Law, our charter and our bylaws contain provisions that may discourage, delay or make more difficult a change in control of Apollo Investment or the removal of our directors. We are subject to the Maryland Business Combination Act, subject to any applicable requirements of the 1940 Act. Our board of directors has adopted a resolution exempting from the Business Combination Act any business combination between us and any other person, subject to prior approval of such business combination by our board of directors, including approval by a majority of our disinterested directors. If the resolution exempting business combinations is repealed or our board of directors does not approve a business combination, the Business Combination Act may discourage third parties from trying to acquire control of us and increase the difficulty of consummating such an offer. Our bylaws exempt from the Maryland Control Share Acquisition Act acquisitions of our common stock by any person. If we amend our bylaws to repeal the exemption from the Control Share Acquisition Act, the Control Share Acquisition Act also may make it more difficult for a third party to obtain control of us and increase the difficulty of consummating such an offer.

Classified board of directors

Our board of directors is divided into three classes of directors serving staggered three-year terms. The initial terms of the first, second and third classes have one, two and three years, respectively. At each annual meeting of our stockholders, the successors to the class of directors whose terms expire at such meeting will be elected to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election. Each director holds office for the term to which he or she is elected and until his or her successor is duly elected and qualifies. A classified board of directors may render a change in control of us or removal of our incumbent management more difficult. We believe, however, that the longer time required to elect a majority of a classified board of directors will help to ensure the continuity and stability of our management and policies.

Election of directors

Our charter and bylaws provide that the affirmative vote of the holders of a majority of the outstanding shares of stock entitled to vote in the election of directors will be required to elect a director. Pursuant to the charter, our board of directors may amend the bylaws to alter the vote required to elect directors.

Number of directors; vacancies; removal

Our charter provides that the number of directors will be set only by the board of directors in accordance with our bylaws. Our bylaws provide that a majority of our entire board of directors may at any time increase or decrease the number of directors. However, unless our bylaws are amended, the number of directors may never be less than four nor more than eight. Our charter provides that, at such time as we have three independent directors and our common stock is registered under the Exchange Act, we elect to be subject to the provision of Subtitle 8 of Title 3 of the Maryland General Corporation Law regarding the filling of vacancies on the board of directors. Accordingly, at such time, except as may be provided by the board of directors in setting the terms of any class or series of preferred stock, any and all vacancies on the board of directors may be filled only by the affirmative vote of a majority of the remaining directors in office, even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy will serve for the remainder of the full term of the directorship in which the vacancy occurred and until a successor is elected and qualifies, subject to any applicable requirements of the 1940 Act.

Our charter provides that a director may be removed only for cause, as defined in our charter, and then only by the affirmative vote of at least two-thirds of the votes entitled to be cast in the election of directors.

Action by stockholders

Under the Maryland General Corporation Law, stockholder action can be taken only at an annual or special meeting of stockholders or by unanimous written consent in lieu of a meeting, unless the charter provides for stockholder action by less than unanimous written consent (which our charter does not). These provisions, combined with the requirements of our bylaws regarding the calling of a stockholder-requested special meeting of stockholders discussed below, may have the effect of delaying consideration of a stockholder proposal until the next annual meeting.

Advance notice provisions for stockholder nominations and stockholder proposals

Our bylaws provide that with respect to an annual meeting of stockholders, nominations of persons for election to the board of directors and the proposal of business to be considered by stockholders may be made only (1) pursuant to our notice of the meeting, (2) by the board of directors or (3) by a stockholder who is entitled to vote at the meeting and who has complied with the advance notice procedures of the bylaws. With respect to special

meetings of stockholders, only the business specified in our notice of the meeting may be brought before the meeting. Nominations of persons for election to the board of directors at a special meeting may be made only (1) pursuant to our notice of the meeting, (2) by the board of directors or (3) provided that the board of directors has determined that directors will be elected at the meeting, by a stockholder who is entitled to vote at the meeting and who has complied with the advance notice provisions of the bylaws.

The purpose of requiring stockholders to give us advance notice of nominations and other business is to afford our board of directors a meaningful opportunity to consider the qualifications of the proposed nominees and the advisability of any other proposed business and, to the extent deemed necessary or desirable by our board of directors, to inform stockholders and make recommendations about such qualifications or business, as well as to provide a more orderly procedure for conducting meetings of stockholders. Although our bylaws do not give our board of directors any power to disapprove stockholder nominations for the election of directors or proposals recommending certain action, they may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if proper procedures are not followed and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal without regard to whether consideration of such nominees or proposals might be harmful or beneficial to us and our stockholders.

Calling of special meetings of stockholders

Our bylaws provide that special meetings of stockholders may be called by our board of directors and certain of our officers. Additionally, our bylaws provide that, subject to the satisfaction of certain procedural and informational requirements by the stockholders requesting the meeting, a special meeting of stockholders will be called by the secretary of the corporation upon the written request of stockholders entitled to cast not less than a majority of all the votes entitled to be cast at such meeting.

Approval of extraordinary corporate action; amendment of charter and bylaws

Under Maryland law, a Maryland corporation generally cannot dissolve, amend its charter, merge, sell all or substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business, unless approved by the affirmative vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter. However, a Maryland corporation may provide in its charter for approval of these matters by a lesser percentage, but not less than a majority of all of the votes entitled to be cast on the matter. Our charter generally provides for approval of charter amendments and extraordinary transactions by the stockholders entitled to cast at least a majority of the votes entitled to be cast on the matter. Our charter also provides that certain charter amendments and any proposal for our conversion, whether by merger or otherwise, from a closed-end company to an open-end company or any proposal for our liquidation or dissolution requires the approval of the stockholders entitled to cast at least 80 percent of the votes entitled to be cast on such matter. However, if such amendment or proposal is approved by at least two-thirds of our continuing directors (in addition to approval by our board of directors), such amendment or proposal may be approved by a majority of the votes entitled to be cast on such a matter. The "continuing directors" are defined in our charter as our current directors as well as those directors whose nomination for election by the stockholders or whose election by the directors to fill vacancies is approved by a majority of the continuing directors then on the board of directors. The holders of any preferred stock outstanding would have a separate class vote on any conversion to an open-end company.

Our charter and bylaws provide that the board of directors will have the exclusive power to adopt, alter or repeal any provision of our bylaws and to make new bylaws.

No appraisal rights

Except with respect to appraisal rights arising in connection with the Maryland Control Share Acquisition Act discussed below, as permitted by the Maryland General Corporation Law, our charter provides that stockholders will not be entitled to exercise appraisal rights.

Control share acquisitions

The Control Share Acquisition Act provides that control shares of a Maryland corporation acquired in a control share acquisition have no voting rights except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter. Shares owned by the acquiror, by officers or by directors who are employees of the corporation are excluded from shares entitled to vote on the matter. Control shares are voting shares of stock which, if aggregated with all other shares of stock owned by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power:

one-tenth or more but less than one-third;

one-third or more but less than a majority; or

a majority or more of all voting power.

The requisite stockholder approval must be obtained each time an acquiror crosses one of the thresholds of voting power set forth above. Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A control share acquisition means the acquisition of control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition may compel the board of directors of the corporation to call a special meeting of stockholders to be held within 50 days of demand to consider the voting rights of the shares. The right to compel the calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the expenses of the meeting. If no request for a meeting is made, the corporation may itself present the question at any stockholders' meeting.

If voting rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then the corporation may repurchase for fair value any or all of the control shares, except those for which voting rights have previously been approved. The right of the corporation to repurchase control shares is subject to certain conditions and limitations, including, as provided in our bylaws, compliance with the 1940 Act. Fair value is determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquiror or of any meeting of stockholders at which the voting rights of the shares are considered and not approved. If voting rights for control shares are approved at a stockholders' meeting and the acquiror becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. The fair value of the shares as determined for purposes of appraisal rights may not be less than the highest price per share paid by the acquiror in the control share acquisition.

The Control Share Acquisition Act does not apply (a) to shares acquired in a merger, consolidation or share exchange if the corporation is a party to the transaction or (b) to acquisitions approved or exempted by the charter or bylaws of the corporation.

Our bylaws contain a provision exempting from the Control Share Acquisition Act any and all acquisitions by any person of our shares of stock. There can be no assurance that such provision will not be amended or eliminated at any time in the future. However, we will amend our bylaws to be subject to the Control Share Acquisition Act only if the board of directors determines that it would be in our best interests based on our determination that our being subject to the Control Share Acquisition Act does not conflict with the 1940 Act.

Business combinations

Under Maryland law, "business combinations" between a Maryland corporation and an interested stockholder or an affiliate of an interested stockholder are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. "Business combinations" include a merger, consolidation, share exchange or, in circumstances specified in the statute, an asset transfer or issuance or reclassification of equity securities. An interested stockholder is defined as:

any person who beneficially owns 10% or more of the voting power of the corporation's shares; or

an affiliate or associate of the corporation who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of the then outstanding voting stock of the corporation.

A person is not an interested stockholder under this statute if the board of directors approved in advance the transaction by which he otherwise would have become an interested stockholder. However, in approving a transaction, the board of directors may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions determined by the board of directors.

After the five-year prohibition, any business combination between the corporation and an interested stockholder generally must be recommended by the board of directors of the corporation and approved by the affirmative vote of at least:

80% of the votes entitled to be cast by holders of outstanding shares of voting stock of the corporation; and

two-thirds of the votes entitled to be cast by holders of voting stock of the corporation other than shares held by the interested stockholder with whom or with whose affiliate the business combination is to be effected or held by an affiliate or associate of the interested stockholder.

These super-majority vote requirements do not apply if the corporation's common stockholders receive a minimum price, as defined under Maryland law, for their shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares.

The statute permits various exemptions from its provisions, including business combinations that are exempted by the board of directors before the time that the interested stockholder becomes an interested stockholder. Our board of directors has adopted a resolution that any business combination between us and any other person is exempted from the provisions of the Business Combination Act, provided that the business combination is first approved by the board of directors, including a majority of the directors who are not interested persons as defined in the 1940 Act. This resolution, however, may be altered or repealed in whole or in part at any time. If this resolution is repealed, or the board of directors does not otherwise approve a business combination, the statute may discourage others from trying to acquire control of us and increase the difficulty of consummating any offer.

Conflict with 1940 Act

Our bylaws provide that, if and to the extent that any provision of the Maryland General Corporation Law, including the Control Share Acquisition Act (if we amend our bylaws to be subject to such Act) and the Business Combination Act, or any provision of our charter or bylaws conflicts with any provision of the 1940 Act, the applicable provision of the 1940 Act will control.

DESCRIPTION OF OUR PREFERRED STOCK

In addition to shares of common stock, our charter authorizes the issuance of preferred stock. We may issue preferred stock from time to time, although we have no immediate intention to do so. If we offer preferred stock under this prospectus, we will issue an appropriate prospectus supplement. We may issue preferred stock from time to time in one or more classes or series, without stockholder approval. Prior to issuance of shares of each class or series, our board of directors is required by Maryland law and by our charter to set the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Any such an issuance must adhere to the requirements of the 1940 Act, Maryland law and any other limitations imposed by law.

The following is a general description of the terms of the preferred stock we may issue from time to time. Particular terms of any preferred stock we offer will be described in the prospectus supplement relating to such preferred stock.

If we issue preferred stock, it will pay dividends to the holders of the preferred stock at either a fixed rate or a rate that will be reset frequently based on short-term interest rates, as described in a prospectus supplement accompanying each preferred share offering.

The 1940 Act requires, among other things, that (1) immediately after issuance and before any distribution is made with respect to common stock, the liquidation preference of the preferred stock, together with all other senior securities, must not exceed an amount equal to 50% of our total assets (taking into account such distribution), (2) the holders of shares of preferred stock, if any are issued, must be entitled as a class to elect two directors at all times and to elect a majority of the directors if dividends on the preferred stock are in arrears by two years or more and (3) such shares be cumulative as to dividends and have a complete preference over our common stock to payment of their liquidation preference in the event of a dissolution.

For any series of preferred stock that we may issue, our board of directors or a committee thereof will determine and the Articles Supplementary and prospectus supplement relating to such series will describe:

the designation and number of shares of such series;

the rate, whether fixed or variable, and time at which any dividends will be paid on shares of such series, as well as whether such dividends are participating or non-participating;

any provisions relating to convertibility or exchangeability of the shares of such series;

the rights and preferences, if any, of holders of shares of such series upon our liquidation, dissolution or winding up of our affairs;

the voting powers, if any, of the holders of shares of such series;

any provisions relating to the redemption of the shares of such series;

any limitations on our ability to pay dividends or make distributions on, or acquire or redeem, other securities while shares of such series are outstanding;

any conditions or restrictions on our ability to issue additional shares of such series or other securities;

if applicable, a discussion of certain U.S. federal income tax considerations; and

any other relative powers, preferences and participating, optional or special rights of shares of such series, and the qualifications, limitations or restrictions thereof.

All shares of preferred stock that we may issue will be identical and of equal rank except as to the particular terms thereof that may be fixed by our board of directors, and all shares of each series of preferred stock will be identical and of equal rank except as to the dates from which dividends thereon will be cumulative.

DESCRIPTION OF OUR WARRANTS

The following is a general description of the terms of the warrants we may issue from time to time. Particular terms of any warrants we offer will be described in the prospectus supplement relating to such warrants.

We may issue warrants to purchase shares of our common stock. Such warrants may be issued independently or together with shares of common stock and may be attached or separate from such shares of common stock. We will issue each series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

A prospectus supplement will describe the particular terms of any series of warrants we may issue, including the following:

the title of such warrants;

the aggregate number of such warrants;

the price or prices at which such warrants will be issued;

the currency or currencies, including composite currencies, in which the price of such warrants may be payable;

the number of shares of common stock issuable upon exercise of such warrants;

the price at which and the currency or currencies, including composite currencies, in which the shares of common stock purchasable upon exercise of such warrants may be purchased;

the date on which the right to exercise such warrants shall commence and the date on which such right will expire;

whether such warrants will be issued in registered form or bearer form;

if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time;

if applicable, the number of such warrants issued with each share of common stock;

if applicable, the date on and after which such warrants and the related shares of common stock will be separately transferable;

information with respect to book-entry procedures, if any;

if applicable, a discussion of certain U.S. federal income tax considerations; and

any other terms of such warrants, including terms, procedures and limitations relating to the exchange and exercise of such warrants.

We and the warrant agent may amend or supplement the warrant agreement for a series of warrants without the consent of the holders of the warrants issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants.

Under the 1940 Act, we may generally only offer warrants provided that (1) the warrants expire by their terms within ten years; (2) the exercise or conversion price is not less than the current market value at the date of issuance; (3) our stockholders authorize the proposal to issue such warrants, and our board of directors approves such issuance on the basis that the issuance is in the best interests of Apollo Investment and its stockholders; and (4) if the warrants are accompanied by other securities, the warrants are not separately transferable unless no class of such warrants and the securities accompanying them has been publicly distributed. The 1940 Act also provides that the amount of our voting securities that would result from the exercise of all outstanding warrants at the time of issuance may not exceed 25% of our outstanding voting securities.

DESCRIPTION OF OUR DEBT SECURITIES

We may issue debt securities in one or more series. The specific terms of each series of debt securities will be described in the particular prospectus supplement relating to that series. The prospectus supplement may or may not modify the general terms found in this prospectus and will be filed with the SEC. For a complete description of the terms of a particular series of debt securities, you should read both this prospectus and the prospectus supplement relating to that particular series.

As required by federal law for all bonds and notes of companies that are publicly offered, the debt securities are governed by a document called an "indenture." An indenture is a contract between us and JPMorgan Chase Bank, a financial institution acting as trustee on your behalf, and is subject to and governed by the Trust Indenture Act of 1939, as amended. The trustee has two main roles. First, the trustee can enforce your rights against

us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described in the second paragraph under "Events of Default—Remedies if an Event of Default Occurs." Second, the trustee performs certain administrative duties for us.

Because this section is a summary, it does not describe every aspect of the debt securities and the indenture. We urge you to read the indenture because it, and not this description, defines your rights as a holder of debt securities. For example, in this section, we use capitalized words to signify terms that are specifically defined in the indenture. Some of the definitions are repeated in this prospectus, but for the rest you will need to read the indenture. We will file the form of the indenture with the SEC prior to the commencement of any debt offering, at which time the form of indenture would be publicly available See "Available Information" for information on how to obtain a copy of the indenture.

The prospectus supplement, which will accompany this prospectus, will describe the particular series of debt securities being offered by including:

the designation or title of the series of debt securities;

the total principal amount of the series of debt securities;

the percentage of the principal amount at which the series of debt securities will be offered;

the date or dates on which principal will be payable;

the rate or rates (which may be either fixed or variable) and/or the method of determining such rate or rates of interest, if any;

the date or dates from which any interest will accrue, or the method of determining such date or dates, and the date or dates on which any interest will be payable;

the terms for redemption, extension or early repayment, if any;

the currencies in which the series of debt securities are issued and payable;

whether the amount of payments of principal, premium or interest, if any, on a series of debt securities will be determined with reference to an index, formula or other method (which could be based on one or more currencies, commodities, equity indices or other indices) and how these amounts will be determined;

the place or places, if any, other than or in addition to The City of New York, of payment, transfer, conversion and/or exchange of the debt securities;

the denominations in which the offered debt securities will be issued;

the provision for any sinking fund;

any restrictive covenants;

any Events of Default;

whether the series of debt securities are issuable in certificated form;

any provisions for defeasance or covenant defeasance;

any special federal income tax implications, including, if applicable, federal income tax considerations relating to original issue discount;

whether and under what circumstances we will pay additional amounts in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities rather than pay the additional amounts (and the terms of this option);

any provisions for convertibility or exchangeability of the debt securities into or for any other securities;

whether the debt securities are subject to subordination and the terms of such subordination;

the listing, if any, on a securities exchange; and

any other terms.

The debt securities may be secured or unsecured obligations. Under the provisions of the 1940 Act, we are permitted, as a BDC, to issue debt only in amounts such that our asset coverage, as defined in the 1940 Act, equals at least 200% after each issuance of debt. Unless the prospectus supplement states otherwise, principal (and premium, if any) and interest, if any, will be paid by us in immediately available funds.

General

The indenture provides that any debt securities proposed to be sold under this prospectus and the attached prospectus supplement ("offered debt securities") and any debt securities issuable upon the exercise of warrants or upon conversion or exchange of other offered securities ("underlying debt securities"), may be issued under the indenture in one or more series.

For purposes of this prospectus, any reference to the payment of principal of or premium or interest, if any, on debt securities will include additional amounts if required by the terms of the debt securities.

The indenture limits the amount of debt securities that may be issued thereunder from time to time. Debt securities issued under the indenture, when a single trustee is acting for all debt securities issued under the indenture, are called the "indenture securities". The indenture also provides that there may be more than one trustee thereunder, each with respect to one or more different series of indenture securities. See "Resignation of Trustee" below. At a time when two or more trustees are acting under the indenture, each with respect to only certain series, the term "indenture securities" means the one or more series of debt securities with respect to which each respective trustee is acting. In the event that there is more than one trustee under the indenture, the powers and trust obligations of each trustee described in this prospectus will extend only to the one or more series of indenture securities for which it is trustee. If two or more trustees are acting under the indenture, then the indenture securities for which each trustee is acting would be treated as if issued under separate indentures.

The indenture does not contain any provisions that give you protection in the event we issue a large amount of debt or we are acquired by another entity.

We refer you to the prospectus supplement for information with respect to any deletions from, modifications of or additions to the Events of Default or our covenants that are described below, including any addition of a covenant or other provision providing event risk or similar protection.

We have the ability to issue indenture securities with terms different from those of indenture securities previously issued and, without the consent of the holders thereof, to reopen a previous issue of a series of indenture securities and issue additional indenture securities of that series unless the reopening was restricted when that series was created.

Conversion and Exchange

If any debt securities are convertible into or exchangeable for other securities, the prospectus supplement will explain the terms and conditions of the conversion or exchange, including the conversion price or exchange ratio (or the calculation method), the conversion or exchange period (or how the period will be determined), if conversion or exchange will be mandatory or at the option of the holder or us, provisions for adjusting the

conversion price or the exchange ratio and provisions affecting conversion or exchange in the event of the redemption of the underlying debt securities. These terms may also include provisions under which the number or amount of other securities to be received by the holders of the debt securities upon conversion or exchange would be calculated according to the market price of the other securities as of a time stated in the prospectus supplement.

Issuance of Securities in Registered Form

We may issue the debt securities in registered form, in which case we may issue them either in book-entry form only or in "certificated" form. Debt securities issued in book-entry form will be represented by global securities. We expect that we will usually issue debt securities in book-entry only form represented by global securities.

We also will have the option of issuing debt securities in non-registered form as bearer securities if we issue the securities outside the United States to non-U.S. persons. In that case, the prospectus supplement will set forth the mechanics for holding the bearer securities, including the procedures for receiving payments, for exchanging the bearer securities, including the procedures for receiving payments, for exchanging the bearer securities for registered securities of the same series, and for receiving notices. The prospectus supplement will also describe the requirements with respect to our maintenance of offices or agencies outside the United States and the applicable U.S. federal tax law requirements.

Book-Entry Holders

We will issue registered debt securities in book-entry form only, unless we specify otherwise in the applicable prospectus supplement. This means debt securities will be represented by one or more global securities registered in the name of a depositary that will hold them on behalf of financial institutions that participate in the depositary's book-entry system. These participating institutions, in turn, hold beneficial interests in the debt securities held by the depositary or its nominee. These institutions may hold these interests on behalf of themselves or customers.

Under the indenture, only the person in whose name a debt security is registered is recognized as the holder of that debt security. Consequently, for debt securities issued in book-entry form, we will recognize only the depositary as the holder of the debt securities and we will make all payments on the debt securities to the depositary. The depositary will then pass along the payments it receives to its participants, which in turn will pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the debt securities.

As a result, investors will not own debt securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary's book-entry system or holds an interest through a participant. As long as the debt securities are represented by one or more global securities, investors will be indirect holders, and not holders, of the debt securities.

Street Name Holders

In the future, we may issue debt securities in certificated form or terminate a global security. In these cases, investors may choose to hold their debt securities in their own names or in "street name." Debt securities held in street name are registered in the name of a bank, broker or other financial institution chosen by the investor, and the investor would hold a beneficial interest in those debt securities through the account he or she maintains at that institution.

For debt securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the debt securities are registered as the holders of those debt securities and we will make all payments on those debt securities to them. These institutions will pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold debt securities in street name will be indirect holders, and not holders, of the debt securities.

Legal Holders

Our obligations, as well as the obligations of the applicable trustee and those of any third parties employed by us or the applicable trustee, run only to the legal holders of the debt securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a debt security or has no choice because we are issuing the debt securities only in book-entry form.

For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose (for example, to amend an indenture or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of an indenture), we would seek the approval only from the holders, and not the indirect holders, of the debt securities. Whether and how the holders contact the indirect holders is up to the holders.

When we refer to you, we mean those who invest in the debt securities being offered by this prospectus, whether they are the holders or only indirect holders of those debt securities. When we refer to your debt securities, we mean the debt securities in which you hold a direct or indirect interest.

Special Considerations for Indirect Holders

If you hold debt securities through a bank, broker or other financial institution, either in book-entry form or in street name, we urge you to check with that institution to find out:

how it handles securities payments and notices,

whether it imposes fees or charges,

how it would handle a request for the holders' consent, if ever required,

whether and how you can instruct it to send you debt securities registered in your own name so you can be a holder, if that is permitted in the future for a particular series of debt securities,

how it would exercise rights under the debt securities if there were a default or other event triggering the need for holders to act to protect their interests, and

if the debt securities are in book-entry form, how the depositary's rules and procedures will affect these matters.

Global Securities

As noted above, we usually will issue debt securities as registered securities in book-entry form only. A global security represents one or any other number of individual debt securities. Generally, all debt securities represented by the same global securities will have the same terms.

Each debt security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, New York, known as DTC, will be the depositary for all debt securities issued in book-entry form.

A global security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. We describe those situations below under "Special Situations when a Global Security Will Be Terminated". As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all debt securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an

account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that has an account with the depositary. Thus, an investor whose security is represented by a global security will not be a holder of the debt security, but only an indirect holder of a beneficial interest in the global security.

Special Considerations for Global Securities

As an indirect holder, an investor's rights relating to a global security will be governed by the account rules of the investor's financial institution and of the depositary, as well as general laws relating to securities transfers. The depositary that holds the global security will be considered the holder of the debt securities represented by the global security.

If debt securities are issued only in the form of a global security, an investor should be aware of the following:

An investor cannot cause the debt securities to be registered in his or her name, and cannot obtain certificates for his or her interest in the debt securities, except in the special situations we describe below.

An investor will be an indirect holder and must look to his or her own bank or broker for payments on the debt securities and protection of his or her legal rights relating to the debt securities, as we describe under "Issuance of Securities in Registered Form" above.

An investor may not be able to sell interests in the debt securities to some insurance companies and other institutions that are required by law to own their securities in non-book-entry form.

An investor may not be able to pledge his or her interest in a global security in circumstances where certificates representing the debt securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective.

The depositary's policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to an investor's interest in a global security. We and the trustee have no responsibility for any aspect of the depositary's actions or for its records of ownership interests in a global security. We and the trustee also do not supervise the depositary in any way.

If we redeem less than all the debt securities of a particular series being redeemed, DTC's practice is to determine by lot the amount to be redeemed from each of its participants holding that series.

An investor is required to give notice of exercise of any option to elect repayment of its debt securities, through its participant, to the applicable trustee and to deliver the related debt securities by causing its participant to transfer its interest in those debt securities, on DTC's records, to the applicable trustee.

DTC requires that those who purchase and sell interests in a global security deposited in its book-entry system use immediately available funds. Your broker or bank may also require you to use immediately available funds when purchasing or selling interests in a global security.

Financial institutions that participate in the depositary's book-entry system, and through which an investor holds its interest in a global security, may also have their own policies affecting payments, notices and other matters relating to the debt securities. There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.

Special Situations when a Global Security will be Terminated

In a few special situations described below, a global security will be terminated and interests in it will be exchanged for certificates in non-book-entry form (certificated securities). After that exchange, the choice of whether to hold the certificated debt securities directly or in street name will be up to the investor. Investors must

consult their own banks or brokers to find out how to have their interests in a global security transferred on termination to their own names, so that they will be holders. We have described the rights of legal holders and street name investors under "Issuance of Securities in Registered Form" above.

The special situations for termination of a global security are as follows:

if the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security, and we do not appoint another institution to act as depositary within 60 days,

if we notify the trustee that we wish to terminate that global security, or

if an event of default has occurred with regard to the debt securities represented by that global security and has not been cured or waived; we discuss defaults later under "Events of Default."

The prospectus supplement may list situations for terminating a global security that would apply only to the particular series of debt securities covered by the prospectus supplement. If a global security is terminated, only the depositary, and not we or the applicable trustee, is responsible for deciding the names of the institutions in whose names the debt securities represented by the global security will be registered and, therefore, who will be the holders of those debt securities.

Payment and Paying Agents

We will pay interest to the person listed in the applicable trustee's records as the owner of the debt security at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the debt security on the interest due date. That day, usually about two weeks in advance of the interest due date, is called the "record date." Because we will pay all the interest for an interest period to the holders on the record date, holders buying and selling debt securities must work out between themselves the appropriate purchase price. The most common manner is to adjust the sales price of the debt securities to prorate interest fairly between buyer and seller based on their respective ownership periods within the particular interest period. This prorated interest amount is called "accrued interest."

Payments on Global Securities

We will make payments on a global security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder's right to those payments will be governed by the rules and practices of the depositary and its participants, as described under "—Special Considerations for Global Securities."

Payments on Certificated Securities

We will make payments on a certificated debt security as follows. We will pay interest that is due on an interest payment date by check mailed on the interest payment date to the holder at his or her address shown on the trustee's records as of the close of business on the regular record date. We will make all payments of principal and premium, if any, by check at the office of the applicable trustee in New York, NY and/or at other offices that may be specified in the prospectus supplement or in a notice to holders against surrender of the debt security.

Alternatively, if the holder asks us to do so, we will pay any amount that becomes due on the debt security by wire transfer of immediately available funds to an account at a bank in New York City, on the due date. To request payment by wire, the holder must give the applicable trustee or other paying agent appropriate transfer instructions at least 15 business days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person who is the holder on the relevant regular record date. Any wire instructions, once properly given, will remain in effect unless and until new instructions are given in the manner described above.

Payment When Offices Are Closed

If any payment is due on a debt security on a day that is not a business day, we will make the payment on the next day that is a business day. Payments made on the next business day in this situation will be treated under the indenture as if they were made on the original due date, except as otherwise indicated in the attached prospectus supplement. Such payment will not result in a default under any debt security or the indenture, and no interest will accrue on the payment amount from the original due date to the next day that is a business day.

Book-entry and other indirect holders should consult their banks or brokers for information on how they will receive payments on their debt securities.

Events of Default

You will have rights if an Event of Default occurs in respect of the debt securities of your series and is not cured, as described later in this subsection.

The term "Event of Default" in respect of the debt securities of your series means any of the following:

We do not pay the principal of, or any premium on, a debt security of the series on its due date.

We do not pay interest on a debt security of the series within 30 days of its due date.

We do not deposit any sinking fund payment in respect of debt securities of the series on its due date.

We remain in breach of a covenant in respect of debt securities of the series for 60 days after we receive a written notice of default stating we are in breach. The notice must be sent by either the trustee or holders of at least 25% of the principal amount of debt securities of the series.

We file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur.

Any other Event of Default in respect of debt securities of the series described in the prospectus supplement occurs.

An Event of Default for a particular series of debt securities does not necessarily constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. The trustee may withhold notice to the holders of debt securities of any default, except in the payment of principal, premium or interest, if it considers the withholding of notice to be in the best interests of the holders.

Remedies if an Event of Default Occurs

If an Event of Default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the debt securities of the affected series may declare the entire principal amount of all the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. A declaration of acceleration of maturity may be canceled by the holders of a majority in principal amount of the debt securities of the affected series.

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability (called an "indemnity"). (Section 315 of the Trust Indenture Act of 1939) If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. The trustee may refuse to follow those directions in certain circumstances. No delay or omission in exercising any right or remedy will be treated as a waiver of that right, remedy or Event of Default.

Before you are allowed to bypass your trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

You must give your trustee written notice that an Event of Default has occurred and remains uncured.

The holders of at least 25% in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action because of the default and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action.

The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

The holders of a majority in principal amount of the debt securities must not have given the trustee a direction inconsistent with the above notice during that 60-day period.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt securities on or after the due date.

Holders of a majority in principal amount of the debt securities of the affected series may waive any past defaults other than

the payment of principal, any premium or interest or

in respect of a covenant that cannot be modified or amended without the consent of each holder.

Book-entry and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to declare or cancel an acceleration of maturity.

Each year, we will furnish to each trustee a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the debt securities or else specifying any default.

Merger or Consolidation

Under the terms of the indenture, we are generally permitted to consolidate or merge with another entity. We are also permitted to sell all or substantially all of our assets to another entity. However, we may not take any of these actions unless all the following conditions are met:

Where we merge out of existence or sell our assets, the resulting entity must agree to be legally responsible for our obligations under the debt securities.

The merger or sale of assets must not cause a default on the debt securities and we must not already be in default (unless the merger or sale would cure the default). For purposes of this no-default test, a default would include an Event of Default that has occurred and has not been cured, as described under "Events of Default" above. A default for this purpose would also include any event that would be an Event of Default if the requirements for giving us a notice of default or our default having to exist for a specific period of time were disregarded.

Under the indenture, no merger or sale of assets may be made if as a result any of our property or assets or any property or assets of one of our subsidiaries, if any, would become subject to any mortgage, lien or other encumbrance unless either (i) the mortgage, lien or other encumbrance could be created pursuant to the limitation on liens covenant in the indenture (see "Indenture Provisions—Limitation on Liens" below) without equally and ratably securing the indenture securities or (ii) the indenture securities are secured equally and ratably with or prior to the debt secured by the mortgage, lien or other encumbrance.

We must deliver certain certificates and documents to the trustee.

We must satisfy any other requirements specified in the prospectus supplement relating to a particular series of debt securities.

Modification or Waiver

There are three types of changes we can make to the indenture and the debt securities issued thereunder.

Changes Requiring Your Approval

First, there are changes that we cannot make to your debt securities without your specific approval. The following is a list of those types of changes:

change the stated maturity of the principal of, or interest on, a debt security;

reduce any amounts due on a debt security;

reduce the amount of principal payable upon acceleration of the maturity of a security following a default;

adversely affect any right of repayment at the holder's option;

change the place (except as otherwise described in the prospectus or prospectus supplement) or currency of payment on a debt security;

impair your right to sue for payment;

adversely affect any right to convert or exchange a debt security in accordance with its terms;

modify the subordination provisions in the indenture in a manner that is adverse to holders of the debt securities;

reduce the percentage of holders of debt securities whose consent is needed to modify or amend the indenture;

reduce the percentage of holders of debt securities whose consent is needed to waive compliance with certain provisions of the indenture or to waive certain defaults;

modify any other aspect of the provisions of the indenture dealing with supplemental indentures, modification and waiver of past defaults, changes to the quorum or voting requirements or the waiver of certain covenants; and

change any obligation we have to pay additional amounts.

Changes Not Requiring Approval

The second type of change does not require any vote by the holders of the debt securities. This type is limited to clarifications and certain other changes that would not adversely affect holders of the outstanding debt securities in any material respect. We also do not need any approval to make any change that affects only debt securities to be issued under the indenture after the change takes effect.

Changes Requiring Majority Approval

Any other change to the indenture and the debt securities would require the following approval:

If the change affects only one series of debt securities, it must be approved by the holders of a majority in principal amount of that series.

If the change affects more than one series of debt securities issued under the same indenture, it must be approved by the holders of a majority in principal amount of all of the series affected by the change, with all affected series voting together as one class for this purpose.

In each case, the required approval must be given by written consent.

The holders of a majority in principal amount of all of the series of debt securities issued under an indenture, voting together as one class for this purpose, may waive our compliance with some of our covenants in that indenture. However, we cannot obtain a waiver of a payment default or of any of the matters covered by the bullet points included above under "—Changes Requiring Your Approval."

Further Details Concerning Voting

When taking a vote, we will use the following rules to decide how much principal to attribute to a debt security:

For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of these debt securities were accelerated to that date because of a default.

For debt securities whose principal amount is not known (for example, because it is based on an index), we will use a special rule for that debt security described in the prospectus supplement.

For debt securities denominated in one or more foreign currencies, we will use the U.S. dollar equivalent.

Debt securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption. Debt securities will also not be eligible to vote if they have been fully defeased as described later under "Defeasance—Full Defeasance."

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding indenture securities that are entitled to vote or take other action under the indenture. If we set a record date for a vote or other action to be taken by holders of one or more series, that vote or action may be taken only by persons who are holders of outstanding indenture securities of those series on the record date and must be taken within eleven months following the record date.

Book-entry and other indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or the debt securities or request a waiver.

Defeasance

The following provisions will be applicable to each series of debt securities unless we state in the applicable prospectus supplement that the provisions of covenant defeasance and full defeasance will not be applicable to that series.

Covenant Defeasance

Under current United States federal tax law, we can make the deposit described below and be released from some of the restrictive covenants in the indenture under which the particular series was issued. This is called "covenant defeasance". In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay your debt securities. If applicable, you also would be released from the subordination provisions described under "Indenture Provisions—Subordination" below. In order to achieve covenant defeasance, we must do the following:

If the debt securities of the particular series are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of such debt securities a combination of money and United States government or United States government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates.

We must deliver to the trustee a legal opinion of our counsel confirming that, under current United States federal income tax law, we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity.

We must deliver to the trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act, as amended, and a legal opinion and officers' certificate stating that all conditions precedent to covenant defeasance have been complied with.

If we accomplish covenant defeasance, you can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit or the trustee is prevented from making payment. In fact, if one of the remaining Events of Default occurred (such as our bankruptcy) and the debt securities became immediately due and payable, there might be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Full Defeasance

If there is a change in United States federal tax law, as described below, we can legally release ourselves from all payment and other obligations on the debt securities of a particular series (called "full defeasance") if we put in place the following other arrangements for you to be repaid:

We must deliver to the trustee a legal opinion confirming that there has been a change in current United States federal tax law or an IRS ruling that allows us to make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity. Under current United States federal tax law, the deposit and our legal release from the debt securities would be treated as though we paid you your share of the cash and notes or bonds at the time the cash and notes or bonds were deposited in trust in exchange for your debt securities and you would recognize gain or loss on the debt securities at the time of the deposit.

If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the debt securities. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent. If applicable, you would also be released from the subordination provisions described later under "Indenture Provisions—Subordination".

Form, Exchange and Transfer of Certificated Registered Securities

If registered debt securities cease to be issued in book-entry form, they will be issued:

only in fully registered certificated form,

without interest coupons, and

unless we indicate otherwise in the prospectus supplement, in denominations of $1,000 and amounts that are multiples of $1,000.

Holders may exchange their certificated securities for debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed.

Holders may exchange or transfer their certificated securities at the office of their trustee. We have appointed the trustee to act as our agent for registering debt securities in the names of holders transferring debt securities. We may appoint another entity to perform these functions or perform them ourselves.

Holders will not be required to pay a service charge to transfer or exchange their certificated securities, but they may be required to pay any tax or other governmental charge associated with the transfer or exchange. The transfer or exchange will be made only if our transfer agent is satisfied with the holder's proof of legal ownership.

If we have designated additional transfer agents for your debt security, they will be named in your prospectus supplement. We may appoint additional transfer agents or cancel the appointment of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

If any certificated securities of a particular series are redeemable and we redeem less than all the debt securities of that series, we may block the transfer or exchange of those debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of any certificated securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security that will be partially redeemed.

If a registered debt security is issued in book-entry form, only the depositary will be entitled to transfer and exchange the debt security as described in this subsection, since it will be the sole holder of the debt security.

Resignation of Trustee

Each trustee may resign or be removed with respect to one or more series of indenture securities provided that a successor trustee is appointed to act with respect to these series. In the event that two or more persons are acting as trustee with respect to different series of indenture securities under the indenture, each of the trustees will be a trustee of a trust separate and apart from the trust administered by any other trustee.

Indenture Provisions—Limitation on Liens

If we issue indenture securities that are denominated as senior debt securities, we covenant in the indenture that neither we nor any of our subsidiaries, if any, will pledge or subject to any lien any of our or their property or assets unless those senior debt securities issued under the indenture are secured by this pledge or lien equally and ratably with other indebtedness thereby secured. There are excluded from this covenant liens created to secure obligations for the purchase price of physical property, liens of a subsidiary securing indebtedness owed to us, liens existing on property acquired upon exercise of rights arising out of defaults on receivables acquired in the ordinary course of business, sales of receivables accounted for as secured indebtedness in accordance with generally accepted accounting principles, certain liens not related to the borrowing of money and other liens not securing borrowed money aggregating less than $500,000.

Indenture Provisions—Subordination

Upon any distribution of our assets upon our dissolution, winding up, liquidation or reorganization, the payment of the principal of (and premium, if any) and interest, if any, on any indenture securities denominated as subordinated debt securities is to be subordinated to the extent provided in the indenture in right of payment to the prior payment in full of all Senior Indebtedness (as defined below), but our obligation to you to make payment of the principal of (and premium, if any) and interest, if any, on such subordinated debt securities will not otherwise be affected. In addition, no payment on account of principal (or premium, if any), sinking fund or interest, if any, may be made on such subordinated debt securities at any time unless full payment of all amounts due in respect of the principal (and premium, if any), sinking fund and interest on Senior Indebtedness has been made or duly provided for in money or money's worth.

In the event that, notwithstanding the foregoing, any payment by us is received by the trustee in respect of subordinated debt securities or by the holders of any of such subordinated debt securities before all Senior Indebtedness is paid in full, the payment or distribution must be paid over to the holders of the Senior Indebtedness or on their behalf for application to the payment of all the Senior Indebtedness remaining unpaid until all the Senior Indebtedness has been paid in full, after giving effect to any concurrent payment or distribution to the holders of the Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness upon this distribution by us, the holders of such subordinated debt securities will be subrogated to the rights of the holders of the Senior Indebtedness to the extent of payments made to the holders of the Senior Indebtedness out of the distributive share of such subordinated debt securities.

By reason of this subordination, in the event of a distribution of our assets upon our insolvency, certain of our senior creditors may recover more, ratably, than holders of any subordinated debt securities. The indenture provides that these subordination provisions will not apply to money and securities held in trust under the defeasance provisions of the indenture.

Senior Indebtedness is defined in the indenture as the principal of (and premium, if any) and unpaid interest on:

our indebtedness (including indebtedness of others guaranteed by us), whenever created, incurred, assumed or guaranteed, for money borrowed (other than indenture securities issued under the indenture and denominated as subordinated debt securities), unless in the instrument creating or evidencing the same or under which the same is outstanding it is provided that this indebtedness is not senior or prior in right of payment to the subordinated debt securities, and

renewals, extensions, modifications and refinancings of any of this indebtedness.

If this prospectus is being delivered in connection with the offering of a series of indenture securities denominated as subordinated debt securities, the accompanying prospectus supplement will set forth the approximate amount of our Senior Indebtedness outstanding as of a recent date.

The Trustee under the Indenture

JPMorgan Chase Bank will serve as the trustee under the indenture. JPMorgan Chase Bank is one of a number of banks with which we maintain ordinary banking relationships and from which we have obtained a senior secured credit facility and lines of credit.

Certain Considerations Relating to Foreign Currencies

Debt securities denominated or payable in foreign currencies may entail significant risks. These risks include the possibility of significant fluctuations in the foreign currency markets, the imposition or modification of foreign exchange controls and potential illiquidity in the secondary market. These risks will vary depending upon the currency or currencies involved and will be more fully described in the applicable prospectus supplement.

REGULATION

We have elected to be treated as a BDC under the 1940 Act and have elected to be treated as a RIC under Subchapter M of the Code. The 1940 Act contains prohibitions and restrictions relating to transactions between business development companies and their affiliates (including any investment advisers or sub-advisers), principal underwriters and affiliates of those affiliates or underwriters and requires that a majority of the directors be persons other than "interested persons," as that term is defined in the 1940 Act. In addition, the 1940 Act provides that we may not change the nature of our business so as to cease to be, or to withdraw our election as, a BDC unless approved by a majority of our outstanding voting securities voting as a class. A majority of our outstanding voting securities is defined under the 1940 Act as the lesser of (i) 67% or more of our shares present at a meeting or represented by proxy if more than 50% of our outstanding shares are present or represented by proxy or (ii) more than 50% of our outstanding shares.

We may invest up to 100% of our assets in securities acquired directly from issuers in privately negotiated transactions. With respect to such securities, we may, for the purpose of public resale, be deemed an "underwriter" as that term is defined in the Securities Act. However, we may purchase or otherwise receive warrants to purchase the common stock of our portfolio companies in connection with acquisition financing or other investment. Similarly, in connection with an acquisition, we may acquire rights to require the issuers of acquired securities or their affiliates to repurchase them under certain circumstances. We also do not intend to acquire securities issued by any investment company that exceed the limits imposed by the 1940 Act. Under these limits, we generally cannot acquire more than 3% of the voting stock of any registered investment company, invest more than 5% of the value of our total assets in the securities of one investment company or invest more than 10% of the value of our total assets in the securities of more than one investment company. With regard to that portion of our portfolio invested in securities issued by investment companies, it should be noted that such investments might subject our stockholders to additional expenses. None of our policies is fundamental, and each may be changed without stockholder approval.

Qualifying Assets

Under the 1940 Act, a BDC may not acquire any asset other than assets of the type listed in Section 55(a) of the 1940 Act, which are referred to as "qualifying assets, " unless, at the time the acquisition is made, qualifying assets represent at least 70% of the company's total assets. The principal categories of qualifying assets relevant to our business are the following:

(1) Securities of an "eligible portfolio company," purchased in transactions not involving any public offering. An eligible portfolio company is defined in the 1940 Act as any issuer which:

(a) is organized under the laws of, and has its principal place of business in, the United States;

(b) is not an investment company (other than a small business investment company wholly owned by the BDC) or a company that would be an investment company but for certain exclusions under the 1940 Act; and

does not have any class of securities listed on a national securities exchange or has a class of securities listed on a national securities exchange but has an aggregate market value of outstanding equity of less than $250 million.

is controlled by a BDC or a group of companies including a BDC, and the BDC has an affiliated person who is a director of the eligible portfolio company; or

is a small and solvent company having total assets of not more than $4 million and capital and surplus of not less than $2 million.

(2) Securities of any eligible portfolio company that we control.

(3) Securities purchased in a private transaction from a U.S. issuer that is not an investment company or from an affiliated person of the issuer, or in transactions incident thereto, if the issuer is in bankruptcy and subject to reorganization or if the issuer, immediately prior to the purchase of its securities were unable to meet its obligations as they came due without material assistance other than conventional lending or financing arrangements.

(4) Securities of an eligible portfolio company purchased from any person in a private transaction if there is no ready market for such securities and we already own 60% of the outstanding equity of the eligible portfolio company.

(5) Securities received in exchange for or distributed on or with respect to securities described in (1) through (4) above, or pursuant to the exercise of options, warrants or rights relating to such securities.

(6) Cash, cash equivalents, U.S. Government securities or high-quality debt securities maturing in one year or less from the time of investment.

Managerial Assistance to Portfolio Companies

In addition, a BDC must have been organized and have its principal place of business in the United States and must be operated for the purpose of making investments in the types of securities described in (1), (2) or (3) above. However, in order to count portfolio securities as qualifying assets for the purpose of the 70% test, the BDC must either control the issuer of the securities or must offer to make available to the issuer of the securities (other than small and solvent companies described above) significant managerial assistance; except that, where the BDC purchases such securities in conjunction with one or more other persons acting together, one of the other persons in the group may make available such managerial assistance. Making available managerial assistance means, among other things, any arrangement whereby the BDC, through its directors, officers or employees, offers to provide, and, if accepted, does so provide, significant guidance and counsel concerning the management, operations or business objectives and policies of a portfolio company.

Temporary Investments

Pending investment in other types of "qualifying assets," as described above, our investments may consist of cash, cash equivalents, U.S. Government securities or high-quality debt securities maturing in one year or less from the time of investment, which we refer to, collectively, as temporary investments, so that 70% of our assets are qualifying assets. Typically, we will invest in U.S. Treasury bills or in repurchase agreements, provided that such agreements are fully collateralized by cash or securities issued by the U.S. Government or its agencies. A repurchase agreement involves the purchase by an investor, such as us, of a specified security and the simultaneous agreement by the seller to repurchase it at an agreed-upon future date and at a price that is greater than the purchase price by an amount that reflects an agreed-upon interest rate. There is no percentage restriction on the proportion of our assets that may be invested in such repurchase agreements. If, however, more than 25% of our total assets constitute repurchase agreements that are treated under applicable tax rules as being issued by a single counterparty, we would not meet the diversification tests imposed on us by the Code to qualify for tax treatment as a RIC for U.S. federal income tax purposes. Thus, we do not intend to enter into repurchase agreements with a single counterparty in excess of 25% of our assets. We monitor the creditworthiness of the counterparties with which we enter into repurchase agreement transactions.

Senior Securities

We are permitted, under specified conditions, to issue multiple classes of indebtedness and one class of stock senior to our common stock if our asset coverage, as defined in the 1940 Act, is at least equal to 200% immediately after each such issuance. In addition, while any of these types of senior securities remain outstanding, we must make provisions to prohibit any distribution to our stockholders or the repurchase of such securities or shares unless we meet the applicable asset coverage ratios at the time of the distribution or repurchase. We may also borrow amounts up to 5% of the value of our total assets for temporary or emergency purposes without regard to asset coverage. For a discussion of the risks associated with leverage, see "Risk Factors—Risks relating to our business and structure—Regulations governing our operation as a BDC will affect our ability to, and the way in which we, raise additional capital."

Code of Ethics

We have adopted a code of ethics pursuant to Rule 17j-1 under the 1940 Act and we have also approved AIM's code of ethics that was adopted by it in accordance with Rule 17j-1 and Rule 204A-1 under the Advisers Act. These codes of ethics establish procedures for personal investments and restrict certain personal securities transactions. Personnel subject to a code may invest in securities for their personal investment accounts, including securities that may be purchased or held by us, so long as such investments are made in accordance with the code's requirements. For information on how to obtain a copy of each code of ethics, see "Available Information."

Proxy Voting Policies and Procedures

SEC-registered investment advisers that have the authority to vote (client) proxies (which authority may be implied from a general grant of investment discretion) are required to adopt policies and procedures reasonably designed to ensure that the investment adviser votes proxies in the best interests of its clients. Registered investment

advisers also must maintain certain records on proxy voting. When Apollo Investment does have voting rights, it will delegate the exercise of such rights to AIM. AIM's proxy voting policies and procedures are summarized below:

In determining how to vote, officers of our investment adviser will consult with each other and other investment professionals of Apollo, taking into account the interests of Apollo Investment and its investors as well as any potential conflicts of interest. Our investment adviser will consult with legal counsel to identify potential conflicts of interest. Where a potential conflict of interest exists, our investment adviser may, if it so elects, resolve it by following the recommendation of a disinterested third party, by seeking the direction of the independent directors of Apollo Investment or, in extreme cases, by abstaining from voting. While our investment adviser may retain an outside service to provide voting recommendations and to assist in analyzing votes, our investment adviser will not delegate its voting authority to any third party.

An officer of AIM will keep a written record of how all such proxies are voted. Our investment adviser will retain records of (1) proxy voting policies and procedures, (2) all proxy statements received (or it may rely on proxy statements filed on the SEC's EDGAR system in lieu thereof), (3) all votes cast, (4) investor requests for voting information, and (5) any specific documents prepared or received in connection with a decision on a proxy vote. If it uses an outside service, our investment adviser may rely on such service to maintain copies of proxy statements and records, so long as such service will provide a copy of such documents promptly upon request.

Our investment adviser's proxy voting policies are not exhaustive and are designed to be responsive to the wide range of issues that may be subject to a proxy vote. In general, our investment adviser will vote our proxies in accordance with these guidelines unless: (1) it has determined otherwise due to the specific and unusual facts and circumstances with respect to a particular vote, (2) the subject matter of the vote is not covered by these guidelines, (3) a material conflict of interest is present, or (4) we find it necessary to vote contrary to our general guidelines to maximize shareholder value or the best interests of Apollo Investment. In reviewing proxy issues, our investment adviser generally will use the following guidelines:

Elections of Directors: In general, our investment adviser will vote in favor of the management-proposed slate of directors. If there is a proxy fight for seats on a portfolio company's board of directors or our investment adviser determines that there are other compelling reasons for withholding our vote, it will determine the appropriate vote on the matter. We may withhold votes for directors that fail to act on key issues, such as failure to: (1) implement proposals to declassify a board of directors, (2) implement a majority vote requirement, (3) submit a rights plan to a shareholder vote or (4) act on tender offers where a majority of shareholders have tendered their shares. Finally, our investment adviser may withhold votes for directors of non-U.S. issuers where there is insufficient information about the nominees disclosed in the proxy statement.

Appointment of Auditors: We believe that a portfolio company remains in the best position to choose its independent auditors, and our investment adviser will generally support management's recommendation in this regard.

Changes in Capital Structure: Changes in a portfolio company's charter or bylaws may be required by state or federal regulation. In general, our investment adviser will cast our votes in accordance with the management on such proposals. However, our investment adviser will consider carefully any proposal regarding a change in corporate structure that is not required by state or federal regulation.

Corporate Restructurings, Mergers and Acquisitions: We believe proxy votes dealing with corporate reorganizations are an extension of the investment decision. Accordingly, our investment adviser will analyze such proposals on a case-by-case basis and vote in accordance with its perception of our interests.

Proposals Affecting Shareholder Rights: We will generally vote in favor of proposals that give shareholders a greater voice in the affairs of a portfolio company and oppose any measure that seeks to limit such rights. However, when analyzing such proposals, our investment adviser will balance the financial impact of the proposal against any impairment of shareholder rights as well as of our investment in the portfolio company.

Corporate Governance: We recognize the importance of good corporate governance. Accordingly, our investment adviser will generally favor proposals that promote transparency and accountability within a portfolio company.

Anti-Takeover Measures: Our investment adviser will evaluate, on a case-by-case basis, any proposals regarding anti-takeover measures to determine the measure's likely effect on shareholder value dilution.

Stock Splits: Our investment adviser will generally vote with management on stock split matters.

Limited Liability of Directors: Our investment adviser will generally vote with management on matters that could adversely affect the limited liability of directors.

Social and Corporate Responsibility: Our investment adviser will review proposals related to social, political and environmental issues to determine whether they may adversely affect shareholder value. Our investment adviser may abstain from voting on such proposals where they do not have a readily determinable financial impact on shareholder value.

Other

We may also be prohibited under the 1940 Act from knowingly participating in certain transactions with our affiliates without the prior approval of our board of directors who are not interested persons and, in some cases, prior approval by the SEC.

We will be periodically examined by the SEC for compliance with the 1940 Act.

We are required to provide and maintain a bond issued by a reputable fidelity insurance company to protect us against larceny and embezzlement. Furthermore, as a BDC, we are prohibited from protecting any director or officer against any liability to Apollo Investment or our stockholders arising from willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such person's office.

We and AIM have adopted and implemented written policies and procedures reasonably designed to prevent violation of the federal securities laws and intend to review these policies and procedures annually for their adequacy and the effectiveness of their implementation. We have designated a chief compliance officer to be responsible for administering our compliance policies and procedures.

Compliance with the Sarbanes-Oxley Act of 2002 and The Nasdaq Global Select Market Corporate Governance Regulations

The Sarbanes-Oxley Act of 2002 imposes a wide variety of regulatory requirements on publicly-held companies and their insiders. Many of these requirements affect us. The Sarbanes-Oxley Act has required us to review our policies and procedures to determine whether we comply with the Sarbanes-Oxley Act and the regulations promulgated thereunder. We will continue to monitor our compliance with all future regulations that are adopted under the Sarbanes-Oxley Act and will take actions necessary to ensure that we are in compliance therewith.

In addition, The Nasdaq Global Select Market also adopted corporate governance changes to its listing standards. We believe we are in compliance with such corporate governance listing standards. We will continue to monitor our compliance with all future listing standards and will take actions necessary to ensure that we are in compliance therewith.

CUSTODIAN, TRANSFER AND DIVIDEND PAYING AGENT, REGISTRAR AND TRUSTEE

Our securities are held under a custody agreement by JPMorgan Chase Bank, a global financial services firm. The address of the custodian is: 270 Park Avenue, New York, NY 10017. American Stock Transfer and Trust Company will act as our transfer agent, dividend paying agent and registrar. The principal business address of American Stock Transfer & Trust Company is: 59 Maiden Lane, New York, NY 10007, telephone number: (718) 921-8200. JPMorgan Chase Bank will also act as the trustee. The principal business address of JPMorgan Chase Bank is: 270 Park Avenue, New York, NY 10017.

BROKERAGE ALLOCATION AND OTHER PRACTICES

Since we generally acquire and dispose of our investments in privately negotiated transactions, we infrequently use brokers in the normal course of our business. From the commencement of our operations through March 31, 2008, we have not paid any brokerage commissions. Subject to policies established by our board of directors, our investment adviser is primarily responsible for the execution of the publicly traded securities portion of our portfolio transactions and the allocation of brokerage commissions. Our investment adviser does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for us, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, and operational facilities of the firm and the firm's risk and skill in positioning blocks of securities. While our investment adviser generally seeks reasonably competitive trade execution costs, we will not necessarily pay the lowest spread or commission available. Subject to applicable legal requirements, our investment adviser may select a broker based partly upon brokerage or research services provided to the investment adviser and us and any other clients. In return for such services, we may pay a higher commission than other brokers would charge if our investment adviser determines in good faith that such commission is reasonable in relation to the services provided.

PLAN OF DISTRIBUTION

We may sell the securities in any of three ways (or in any combination): (a) through underwriters or dealers; (b) directly to a limited number of purchasers or to a single purchaser; or (c) through agents. The securities may be sold "at-the-market" to or through a market maker or into an existing trading market for the securities, on an exchange or otherwise. The prospectus supplement will set forth the terms of the offering of such securities, including:

the name or names of any underwriters, dealers or agents and the amounts of securities underwritten or purchased by each of them;

the offering price of the securities and the proceeds to us and any discounts, commissions or concessions allowed or reallowed or paid to dealers; and

any securities exchanges on which the securities may be listed.

Any offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If underwriters are used in the sale of any securities, the securities will be acquired by the underwriters for their own accounts and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters' obligations to purchase the securities will be subject to certain conditions precedent. The underwriters will be obligated to purchase all of the securities if they purchase any of the securities.

In compliance with the guidelines of FINRA, the maximum compensation to the underwriters or dealers in connection with the sale of our securities pursuant to this prospectus and the accompanying supplement to this prospectus may not exceed 8% of the aggregate offering price of the securities as set forth on the cover page of the supplement to this prospectus.

We may sell the securities through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for soliciting these contracts.

Agents and underwriters may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act of 1933 or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the prospectus supplement applicable to those derivatives so indicates, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). We or one of our affiliates may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus or otherwise.

LEGAL MATTERS

Certain legal matters regarding the securities offered by this prospectus will be passed upon for Apollo Investment by Skadden, Arps, Slate, Meagher & Flom LLP, New York, NY and Venable LLP, Baltimore, MD. Certain legal matters in connection with the offering will be passed upon for the underwriters, if any, by the counsel named in the applicable prospectus supplement.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over financial reporting as of March 31, 2008. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that (i) pertain to assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Management performed an assessment of the effectiveness of the Company's internal control over financial reporting as of March 31, 2008 based upon criteria in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on our assessment, management determined that the Company's internal control over financial reporting was effective as of March 31, 2008 based on the criteria on Internal Control — Integrated Framework issued by COSO.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Apollo Investment Corporation:

In our opinion, the accompanying statements of assets and liabilities including the schedules of investments, and the related statements of operations, changes in net assets, cash flows, and financial highlights present fairly, in all material respects, the financial position of Apollo Investment Corporation ("the Company") at March 31, 2008 and March 31, 2007, and the results of its operations, the changes in net assets, and its cash flows for each of the three years in the period ended March 31, 2008, and the financial highlights for each of the periods presented in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing on page 37 of the annual report to shareholders. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

APOLLO INVESTMENT CORPORATION

NOTES TO FINANCIAL STATEMENTS

(in thousands except share and per share amounts)

Note 1. Organization

Apollo Investment Corporation ("Apollo Investment", the "Company", or "we"), a Maryland corporation organized on February 2, 2004, is a closed-end, non-diversified management investment company that has filed an election to be treated as a business development company ("BDC") under the Investment Company Act of 1940. In addition, for tax purposes we have elected to be treated as a regulated investment company, or RIC, under the Internal Revenue Code of 1986, as amended. Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in middle-market companies in the form of mezzanine and senior secured loans, each of which may include an equity component, and, to a lesser extent, by making direct equity investments in such companies.

Apollo Investment commenced operations on April 8, 2004 receiving net proceeds of $870,000 from its initial public offering selling 62 million shares of common stock at a price of $15.00 per share.

Note 2. Significant Accounting Policies

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 at the date of the financial statements and the reported amounts of income and expenses during the reported period. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ materially.

Our financial statements are prepared in accordance with GAAP and pursuant to the requirements for reporting on Form 10-K and Regulation S-X, as appropriate. In the opinion of management, all adjustments, consisting solely of normal recurring accruals, considered necessary for the fair presentation of financial statements have been included.

The significant accounting policies consistently followed by Apollo Investment are:

(a) Security transactions are accounted for on the trade date;

(b) Investments for which market quotations are readily available are valued at such market quotations unless they are deemed not to represent fair value; debt and equity securities that are not publicly traded or whose market prices are not readily available or whose market quotations are deemed not to represent fair value are valued at fair value as determined in good faith by or under the direction of our Board of Directors. Subordinated debt, senior secured debt and other debt securities with maturities greater than 60 days are valued by an independent pricing service, at the mean between the bid and ask prices from at least two brokers or dealers (if available, otherwise by a principal market maker or a primary market dealer) or by an independent third party valuation firm. With respect to certain private equity securities, each investment is valued by independent third party valuation firms using methods that may, among other measures and as applicable, include comparisons of financial ratios of the portfolio companies that issued such private equity securities to peer companies that are public. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we consider the pricing indicated by the external event to corroborate our private equity valuation. Because we expect that there is no readily available market value for many of the investments in our portfolio, we expect to value such investments at fair value as determined in good faith by or under the direction of our Board of Directors pursuant to a valuation policy and a consistently applied valuation process utilizing the input of the investment adviser, independent valuation firms and the audit committee. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may differ significantly from the values that would have been used had a readily available market value existed for such investments, and the differences could be material.

With respect to investments for which market quotations are not readily available or when such market quotations are not deemed to represent fair value, our board of directors has approved a multi-step valuation process each quarter, as described below:

F-20

APOLLO INVESTMENT CORPORATION

NOTES TO FINANCIAL STATEMENTS (continued)

(in thousands except share and per share amounts)

(1) our quarterly valuation process begins with each portfolio company or investment being initially valued by the investment professionals responsible for the portfolio investment;

(2) preliminary valuation conclusions are then documented and discussed with our senior management;

(3) independent valuation firms engaged by our board of directors conduct independent appraisals and review management's preliminary valuations and their own independent assessment;

(4) the audit committee of our board of directors reviews the preliminary valuation of our investment adviser and that of the independent valuation firms and responds and supplements the valuation recommendation of the independent valuation firm to reflect any comments; and

The types of factors that we may take into account in fair value pricing our investments include, as relevant, the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings and discounted cash flow, the markets in which the portfolio company does business, comparison to publicly traded securities and other relevant factors.

Determination of fair values involves subjective judgments and estimates. Accordingly, these notes to our financial statements express the uncertainty with respect to the possible effect of such valuations, and any change in such valuations, on our financial statements.

(c) purchased within 60 days of maturity are valued at cost plus accreted discount, or minus amortized premium, which approximates value.

(d) Gains or losses on the sale of investments are calculated by using the specific identification method.

(e) Interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis. Origination and/or commitment fees associated with debt investments in portfolio companies are accreted into interest income over the respective terms of the applicable loans. Upon the prepayment of a loan or debt security, any prepayment penalties and unamortized loan origination and/or commitment fees are recorded as interest income. Structuring fees are recorded as other income when earned.

(f) Apollo Investment intends to comply with the applicable provisions of the Internal Revenue Code of 1986, as amended, pertaining to regulated investment companies to make distributions of taxable income sufficient to relieve it from substantially all Federal income taxes. Apollo Investment, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income. Apollo Investment will accrue excise tax on estimated excess taxable income as required.

(g) Book and tax basis differences relating to stockholder dividends and distributions and other permanent book and tax differences are reclassified among the Company's capital accounts. In addition, the character of income and gains to be distributed is determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America; accordingly, at March 31, 2008, $31,837 was reclassified on our balance sheet between accumulated net realized gain and undistributed net investment income and $1,867 was reclassified on our balance sheet between undistributed net investment income and paid-in capital in excess of par. Total earnings and net asset value is not affected;

(h) Dividends and distributions to common stockholders are recorded as of record date. The amount to be paid out as a dividend is determined by the Board of Directors each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, are distributed or deemed distributed at least annually.

NOTES TO FINANCIAL STATEMENTS (continued)

(in thousands except share and per share amounts)

(i) The accounting records of the Company are maintained in U.S. dollars. All assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies against U.S. dollars on the date of valuation. The Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. The Company's investments in foreign securities may involve certain risks such as foreign exchange restrictions, expropriation, taxation or other political, social or economic risks, all of which could affect the market and/or credit risk of the investment. In addition, changes in the relationship of foreign currencies to the U.S. dollar can significantly affect the value of these investments and therefore the earnings of the Company.

(j) The Company may enter into forward exchange contracts in order to hedge against foreign currency risk. These contracts are marked-to-market by recognizing the difference between the contract exchange rate and the current market rate as unrealized appreciation or depreciation. Realized gains or losses are recognized when contracts are settled.

(k) The Company records origination expenses related to its multi-currency revolving credit facility as prepaid assets. These expenses are deferred and amortized using the straight-line method over the stated life of the facility.

(l) The Company records registration expenses related to Shelf filings as prepaid assets. These expenses are charged as a reduction of capital upon utilization, in accordance with Section 8.24 of the AICPA Audit and Accounting Guide for Investment Companies.

(m) Loans are placed on non-accrual status when principal or interest payments are past due 30 days or more and/or when there is reasonable doubt that principal or interest will be collected. Accrued interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management's judgment. Non-accrual loans are restored to accrual status when past due principal and interest is paid and in management's judgment, are likely to remain current.

(n) June 2006, the Financial Accounting Standards Board issued FASB Interpretation No. ("FIN") 48, Accounting for Uncertainty in Income Taxes. FIN 48 is effective for financial statements issued for fiscal years beginning after December 15, 2006. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation requires recognition of the impact of a tax position if that position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In addition, FIN 48 provides measurement guidance whereby a tax position that meets the more-likely-than-not recognition threshold is calculated to determine the amount of benefit to recognize in the financial statements. We have adopted FIN 48 and believe that it does not have a material impact on the Company's financial condition or results of operations. If the tax law requires interest and/or penalties to be paid on an underpayment of income taxes, interest and penalties will be classified as income taxes on our financial statements, if applicable.

(o) In September, 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards ("SFAS") 157, Fair Value Measurements, which assists in clarifying the definition of fair value and requires companies to expand their disclosure about the use of fair value to measure assets and liabilities in interim and annual periods subsequent to initial recognition. Adoption of SFAS 157 generally requires the use of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. We continue to analyze the effect of adoption of this statement on our financial position, including our net asset value and results of operations, but currently believe that it will not have a significant impact on our financial position, including our net asset value and results of operations. We will adopt this statement on a prospective basis beginning in the quarter ending June 30, 2008. The actual impact on our financial statements in the period of adoption and subsequent to the period of

F-22

APOLLO INVESTMENT CORPORATION

NOTES TO FINANCIAL STATEMENTS (continued)

(in thousands except share and per share amounts)

adoption cannot be determined at this time as it will be influenced by the estimates of fair value for that period and the number and amount of investments we originate, acquire or exit.

(p) In February 2007, the Financial Accounting Standards Board ("FASB") issued SFAS 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment of FASB No. 115. This statement permits an entity to choose to measure many financial instruments and certain other items at fair value. This statement applies to all reporting entities, and contains financial statement presentation and disclosure requirements for assets and liabilities reported at fair value as a consequence of the election. This statement is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The Company does not intend to elect fair value measurement for assets or liabilities other than portfolio investments, which are already measured at fair value, therefore, the Company does not believe the adoption of this statement will have a significant effect on the Company's financial position or its results of operations.

Note 3. Agreements

Apollo Investment has an Investment Advisory and Management Agreement with the Investment Adviser, Apollo Investment Management, L.P., under which the Investment Adviser, subject to the overall supervision of Apollo Investment's Board of Directors, will manage the day-to-day operations of, and provide investment advisory services to, Apollo Investment. For providing these services, the Investment Adviser receives a fee from Apollo Investment, consisting of two components—a base management fee and an incentive fee. The base management fee is determined by taking the average value of Apollo Investment's gross assets at the end of the two most recently completed calendar quarters calculated at an annual rate of 2.00%. The incentive fee has two parts, as follows: one part is calculated and payable quarterly in arrears based on Apollo Investment's pre-incentive fee net investment income for the immediately preceding calendar quarter. For this purpose, pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that we receive from portfolio companies) accrued during the calendar quarter, minus Apollo Investment's operating expenses for the quarter (including the base management fee, any expenses payable under the Administration Agreement, and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income does not include any realized capital gains computed net of all realized capital losses and unrealized capital depreciation. Pre-incentive fee net investment income, expressed as a rate of return on the value of Apollo Investment's net assets at the end of the immediately preceding calendar quarter, is compared to the hurdle rate of 1.75% per quarter (7% annualized). Our net investment income used to calculate this part of the incentive fee is also included in the amount of our gross assets used to calculate the 2% base management fee. Apollo Investment pays the Investment Adviser an incentive fee with respect to Apollo Investment's pre-incentive fee net investment income in each calendar quarter as follows: (1) no incentive fee in any calendar quarter in which Apollo Investment's pre-incentive fee net investment income does not exceed the hurdle rate; (2) 100% of Apollo Investment's pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875% in any calendar quarter; and (3) 20% of the amount of Apollo Investment's pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter. These calculations are appropriately pro rated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter. The second part of the incentive fee is determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Advisory and Management Agreement, as-of the termination date), commencing on December 31, 2004, and will equal 20% of Apollo Investment's cumulative realized capital gains less cumulative realized capital losses, unrealized capital depreciation (unrealized depreciation on a gross investment-by-investment basis at the end of each calendar year) and all capital gains upon which prior performance-based capital gains incentive fee payments were previously made to the advisor.

For the fiscal years ended March 31, 2008, 2007 and 2006, the Investment Adviser received $59,871, $40,569 and $23,408, respectively, in base investment advisory and management fees and $46,411, $36,646 and $22,285, respectively, in performance-based net investment income incentive fees from Apollo Investment. At March 31, 2008, 2007, and 2006 the Company accrued $0, $21,266, and $0, respectively, in net realized capital gains based incentive fees. The amount actually payable by the Company is determined as-of the end of each calendar year. For the periods ended December 31, 2007, 2006 and 2005, the Company has paid $5,304, $0, and $0 in net realized capital gain based incentive fees to the Investment Adviser.

Apollo Investment has also entered into an Administration Agreement with Apollo Investment Administration, LLC (the "Administrator") under which the Administrator provides administrative services for Apollo Investment. For providing these services, facilities and personnel, Apollo Investment reimburses the Administrator for Apollo Investment's allocable portion of overhead and other expenses incurred by Apollo Administration in performing its obligations under the Administration Agreement, including rent and Apollo Investment's allocable portion of its chief financial officer and chief compliance officer and their respective staffs. The Administrator will also provide, on Apollo Investment's behalf, managerial assistance to those portfolio companies to which Apollo Investment is required to provide such assistance.

At the fiscal years ended March 31, 2008, 2007 and 2006, the Administrator was reimbursed $3,162, $2,237 and $1,017, respectively, from Apollo Investment on the $3,450, $2,437 and $1,470, respectively, of expenses accrued under the Administration Agreement.

On April 14, 2005, Apollo Investment entered into an $800,000 Senior Secured Revolving Credit Agreement (the "Facility"), among Apollo Investment, the lenders party thereto and JPMorgan Chase Bank, N.A. ("JPMorgan"), as administrative agent for the lenders. Effective December 29, 2005, lenders provided additional commitments in the amount of $100,000, increasing the total facility size to $900,000 on the same terms and conditions as the existing commitments. On March 31, 2006, Apollo Investment Corporation amended and restated its $900,000 senior secured, multi-currency, revolving credit facility due April 14, 2010. The amended Facility increased total commitments outstanding to $1,250,000 and extended the maturity date to April 13, 2011. The amended Facility also permits Apollo to seek additional commitments from new and existing lenders in the future, up to an aggregate amount not to exceed $2,000,000. In February 2007, Apollo Investment increased total commitments to $1,700,000 under the Facility with the same terms. Pricing remains at 100 basis points over LIBOR. The facility is used to supplement Apollo's equity capital to make additional portfolio investments and for general corporate purposes. From time to time, certain of the lenders provide customary commercial and investment banking services to affiliates of Apollo Investment. JPMorgan also serves as custodian and fund accounting agent for Apollo Investment.

Note 4. Net Asset Value Per Share

At March 31, 2008, the Company's total net assets and net asset value per share were $1,897,908 and $15.83, respectively. This compares to total net assets and net asset value per share at March 31, 2007 of $1,849,748 and $17.87, respectively.

Note 9. Cash Equivalents

Pending investment in longer-term portfolio holdings, Apollo Investment makes temporary investments in U.S. Treasury bills (of varying maturities) and repurchase agreements as outlined in our prospectus. These temporary investments are deemed cash equivalents by us and are included in our Schedule of Investments. At the end of each fiscal quarter, Apollo Investment typically takes proactive steps with the objective of enhancing flexibility in the next quarter. From time to time, Apollo Investment purchases U.S. Treasury bills and closes out its position on a net cash basis subsequent to quarter end. Apollo Investment may also utilize repurchase agreements or other balance sheet transactions as it deems appropriate for this purpose. The amounts of these transactions are excluded from total assets for purposes of computing the asset base upon which the management fee is determined and do not increase the amount of funds available to make investments. U.S. Treasury bills with maturities of greater than 60 days from the time of purchase are marked-to-market as per our valuation policy.

Note 10. Repurchase Agreements

The Company enters into repurchase agreements as part of its investment program. The Company's custodian takes possession of collateral pledged by the counterparty. The collateral is marked-to-market daily to ensure that the value, plus accrued interest, is at least equal to the repurchase price. In the event of default of the obligor to repurchase, the Company has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the counterparty to the agreement, realization and/or retention of the collateral or proceeds may be subject to legal proceedings. There were no repurchase agreements outstanding at March 31, 2008 or March 31, 2007.

FEES AND EXPENSES

The following table is intended to assist you in understanding the costs and expenses that an investor in shares of our common stock will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by "you," "us" or "Apollo Investment," or that "we" will pay fees or expenses, stockholders will indirectly bear such fees or expenses as investors in Apollo Investment.

Stockholder transaction expenses:
Sales load (as a percentage of offering price)	% (1)
Offering expenses (as a percentage of offering price)	% (2)
Total stockholder transaction expenses (as a percentage of offering price)	% (3)

Estimated annual expenses (as percentage of net assets attributable to common stock) (4) :
Management fees	% (5)
Incentive fees payable under investment advisory and management agreement (20% of pre-incentive fee net investment income in excess of hurdle and 20% of net realized capital gains net of gross unrealized capital losses)	% (6)
Other expenses	% (7)
Interest and other credit facility related expenses on borrowed funds	% (8)
Total annual expenses as a percentage of net assets (9)	% (5,6,7,8)

Example

The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. These dollar amounts are based upon payment by an investor of a _____% sales load (underwriting discounts and commissions) and the assumption that our annual operating expenses and leverage would remain at the levels set forth in the table above (other than performance-based incentive fees).

	1 year	3 years	5 years	10 years

You would pay the following expenses on a $1,000 investment, assuming a 5% annual return	$	$	$	$

While the example assumes, as required by the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. Assuming a 5% annual return, the incentive fee under the investment advisory and management agreement would not be earned or payable and is not included in the example. This illustration assumes that we will not realize any capital gains computed net of all realized capital losses and gross unrealized capital depreciation in any of the indicated time periods. If we achieve sufficient returns on our investments, including through the realization of capital gains, to trigger an incentive fee of a material amount, our expenses, and returns to our investors, would be higher. In addition, while the example assumes reinvestment of all dividends and distributions at net asset value, participants in our dividend reinvestment plan will receive a number of shares of our common stock, determined by dividing the total dollar amount of the dividend payable to a participant by the market price per share of our common stock at the close of trading on the valuation date for the dividend. See "Dividend Reinvestment Plan" in the accompanying prospectus for additional information regarding our dividend reinvestment plan.

This example and the expenses in the table above should not be considered a representation of our future expenses, and actual expenses may be greater or less than those shown.

________________________

(1)	Represents the underwriting discounts and commissions with respect to the shares to be sold by us in this offering.

S-1

(2)	Based on the public offering price of $_____ per share, which was the last reported closing price on __ ___, 200_.

(3)	The expenses of the dividend reinvestment plan per share are included in "Other expenses."

(4)	"Net assets attributable to common stock" equals net assets as of June 30, 2008 plus the anticipated net proceeds from this offering.

(5)

The contractual management fee is calculated at an annual rate of 2.00% of our average total assets. Annual expenses are based on current fiscal year estimates. For more detailed information about our computation of average total assets, please see Notes 3 and 9 of our interim financial statements dated June 30, 2008 included in this prospectus supplement.

(6)

Assumes that annual incentive fees earned by our investment adviser, AIM, remain consistent with the incentive fees accrued by AIM for the current fiscal quarter. AIM earns incentive fees consisting of two parts. The first part, which is payable quarterly in arrears, is based on our pre-incentive fee net investment income for the immediately preceding calendar quarter. Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets at the end of the immediately preceding calendar quarter, is compared to the hurdle rate of 1.75% quarterly (7% annualized). Our net investment income used to calculate this part of the incentive fee is also included in the amount of our gross assets used to calculate the 2% base management fee (see footnote 5 above). Accordingly, we pay AIM an incentive fee as follows: (1) no incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the hurdle rate; (2) 100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.1875% in any calendar quarter; and (3) 20% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter. These calculations are appropriately pro rated for any period of less than three months. You should be aware that a rise in the general level of interest rates can be expected to lead to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates would make it easier for us to meet or exceed the incentive fee hurdle rate and may result in a substantial increase of the amount of incentive fees payable to our investment adviser with respect to pre-incentive fee net investment income. The second part of the incentive fee will equal 20% of our realized capital gains for the calendar year, if any, computed net of all realized capital losses and unrealized capital depreciation (and incorporating unrealized depreciation on a gross investment-by-investment basis) and is payable in arrears at the end of each calendar year. For a more detailed discussion of the calculation of this fee, see "Management—Investment Advisory and Management Agreement" in the accompanying base prospectus.

(7)

Includes our estimated overhead expenses, including payments under the administration agreement based on our estimated allocable portion of overhead and other expenses incurred by Apollo Investment Administration in performing its obligations under the administration agreement. See "Compensation of Directors and Officers—Administration Agreement" in the accompanying base prospectus.

(8)

Our interest and other credit facility expenses are based on current fiscal year estimates. We currently have $1.7 billion available under our credit facility, of which we had $0.97 billion in borrowings outstanding as of June 30, 2008 . For more information, see "Risk Factors—Risks relating to our business and structure—We fund a portion of our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us." in the accompanying base prospectus and "Interim Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in this prospectus supplement.

(9)

"Total annual expenses" as a percentage of net assets attributable to common stock are higher than the total annual expenses percentage would be for a company that is not leveraged. We borrow money to leverage our net assets and increase our total assets. The SEC requires that the "Total annual expenses" percentage be calculated as a percentage of net assets (defined as total assets less indebtedness), rather than the total assets, including assets that have been funded with borrowed monies. If the "Total annual expenses" percentage were calculated instead as a percentage of total assets as of June 30, 2008 plus anticipated net proceeds from this offering, our "Total annual expenses" would be ___% of total assets. For a presentation and calculation of total annual expenses based on total assets, see page [S-17] in this prospectus supplement.

BUSINESS

This summary highlights some of the information in this prospectus supplement. It is not complete and may not contain all of the information that you may want to consider. You should read carefully the more detailed information set forth under "Risk Factors" in the accompanying prospectus and the other information included in this prospectus supplement and the accompanying prospectus. In this prospectus supplement and the accompanying prospectus, except where the context suggests otherwise, the terms "we," "us," "our," and "Apollo Investment" refer to Apollo Investment Corporation; "AIM" or "investment adviser" refers to Apollo Investment Management, L.P.; "Apollo Administration" or "AIA" refers to Apollo Investment Administration, LLC; and "Apollo" refers to the affiliated companies of Apollo Investment Management, L.P.

Apollo Investment

Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We intend to invest primarily in middle-market companies in the form of mezzanine and senior secured loans, as well as by making equity investments in such companies. From time to time, we may also invest in public companies whose securities are thinly traded.

Our portfolio is comprised primarily of investments in long-term subordinated loans, referred to as mezzanine loans, and senior secured loans of private middle-market companies, and from time to time include equity interests such as common stock, preferred stock, warrants or options. Our targeted investment typically ranges between $20 million and $250 million, although this investment size may vary proportionately as the size of our capital base changes. In this prospectus, we use the term "middle-market" to refer to companies with annual revenues between $50 million and $2 billion. While our primary focus is to generate both current income and capital appreciation through investments in loans and debt securities both senior and subordinated, and private equity, we may invest a portion of the portfolio in opportunistic investments, such as foreign securities.

AIM and its affiliates manage funds that may have investment mandates that are similar, in whole or in part, with ours. AIM and its affiliates may determine that an investment is appropriate both for us and for one or more of those funds. In such event, depending on the availability of such investment and other appropriate factors, AIM may determine that we should invest on a side-by-side basis with one or more funds. We may make all such investments subject to compliance with applicable regulations and interpretations, and our allocation procedures. Certain types of negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance that any such order will be obtained.

During the three months ended June 30, 2008, we invested $184.7 million, across 6 new and 8 existing portfolio companies. This compares to investing $738.6 million in 13 new and 5 existing portfolio companies for the three months ended June 30, 2007. Investments sold or prepaid during the three months ended June 30, 2008 totaled $89.1 million versus $346.9 million for the three months ended June 30, 2007.

At June 30, 2008, our net portfolio consisted of 74 portfolio companies and was invested 23% in senior secured loans, 54% in subordinated debt, 7% in preferred equity and 16% in common equity and warrants versus 64 portfolio companies invested 22% in senior secured loans, 56% in subordinated debt, 6% in preferred equity and 16% in common equity and warrants at June 30, 2007.

The weighted average yields on our senior secured loan portfolio, subordinated debt portfolio and total debt portfolio at our current cost basis were 9.7%, 12.9% and 12.0%, respectively, at June 30, 2008. At June 30, 2007, the yields were 13.1%, 11.9%, and 12.8%, respectively.

Since the initial public offering of Apollo Investment Corporation in April 2004 and through June 30, 2008, total invested capital exceeds $5.3 billion in 118 portfolio companies. Over the same period, Apollo Investment has also completed transactions with 81 different financial sponsors.

S-3

Senior secured loans and European mezzanine loans typically accrue interest at variable rates determined on the basis of a benchmark: LIBOR, EURIBOR, GBP LIBOR, or the prime rate, with stated maturities at origination that typically range from 5 to 10 years. While subordinated debt issued within the United States will typically accrue interest at fixed rates, some of these investments may include zero-coupon, PIK and/or step bonds that accrue income on a constant yield to call or maturity basis. At June 30, 2008, 60% or $1.7 billion of our interest-bearing investment portfolio is fixed rate debt and 40% or $1.1 billion is floating rate debt. At June 30, 2007, 66% or $1.6 billion of our interest-bearing investment portfolio was fixed rate debt and 34% or $830.7 million was floating rate debt.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the _____________ shares of our common stock that we are offering, after deducting estimated expenses of this offering payable by us, will be approximately $_____ million [(or $_____ million, if the over-allotment is exercised in full)] based on a public offering price of $ ___ per share based on the closing price of our common stock on _____, 200_. An increase (or decrease) in the public offering price of $1.00 would increase (or decrease) net proceeds from this offering, after deducting underwriting discounts and commissions, by approximately $ __ million. We may change the size of the offering based on demand or market conditions.). We expect to use the net proceeds from selling shares of our common stock to repay indebtedness owed under our senior credit facility, to make investments in portfolio companies in accordance with our investment objective and for general corporate purposes.

At June 30, 2008, we had approximately $0.97 billion outstanding under our senior credit facility. Our senior credit facility matures on April 13, 2011 and bears interest at an annual rate of LIBOR plus 100 basis points on the outstanding balance. Borrowings under our senior credit facility are used to fund investments in portfolio companies and for general corporate purposes. Amounts repaid under our senior credit facility will remain available for future borrowings.

We anticipate that substantially all of the net proceeds of an offering of securities pursuant to this prospectus will be used for the above purposes within two years, depending on the availability of appropriate investment opportunities consistent with our investment objective and market conditions. Our portfolio currently consists primarily of senior loans, mezzanine and other subordinated debt and equity securities. Pending new investments, we plan to invest a portion of the net proceeds from an offering in cash equivalents, U.S. government securities and other high-quality debt investments that mature in one year or less from the date of investment, to reduce then-outstanding obligations under our credit facility, or for other general corporate purposes. The management fee payable by us will not be reduced while our assets are invested in such securities. See "Regulation—Temporary Investments" in the accompanying base prospectus for additional information about temporary investments we may make while waiting to make longer-term investments in pursuit of our investment objective.

S-11

INTERIM MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

OVERVIEW

We were incorporated under the Maryland General Corporation Law in February 2004. We have elected to be treated as a BDC under the 1940 Act. As such, we are required to comply with certain regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in "qualifying assets," including securities of private or thinly traded public U.S. companies, cash equivalents, U.S. government securities and high-quality debt investments that mature in one year or less. In addition, for federal income tax purposes we have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended. Pursuant to this election and assuming we qualify as a RIC, we generally do not have to pay corporate-level federal income taxes on any income we distribute to our stockholders. We commenced operations on April 8, 2004 upon completion of our initial public offering that raised $870 million in net proceeds selling 62 million shares of our common stock at a price of $15.00 per share. Since then, and through June 30, 2008, we have raised approximately $1.4 billion in net proceeds from additional offerings of common stock.

Investments

As a BDC, we must not acquire any assets other than "qualifying assets" specified in the 1940 Act unless, at the time the acquisition is made, at least 70% of our total assets are qualifying assets (with certain limited exceptions). Qualifying assets include investments in "eligible portfolio companies." Pursuant to rules adopted over the past few years, the SEC expanded the definition of "eligible portfolio company" to include certain public companies that do not have any securities listed on a national securities exchange and companies who have securities listed on a national securities exchange but whose market capitalization is less than $250 million at the time of investment.

Revenue

S-12

Expenses

All investment professionals of AIM and their staff, when and to the extent engaged in providing investment advisory and management services to us, and the compensation and routine overhead expenses of that personnel which is allocable to those services are provided and paid for by AIM. We bear all other costs and expenses of our operations and transactions, including those relating to:

investment advisory and management fees;

calculation of our net asset value (including the cost and expenses of any independent valuation firm);

direct costs and expenses of administration, including auditor and legal costs;

costs of preparing and filing reports or other documents with the SEC;

interest payable on debt, if any, incurred to finance our investments;

offerings of our common stock and other securities;

registration and listing fees;

fees payable to third parties, including agents, consultants or other advisors, relating to, or associated with, evaluating and making investments;

transfer agent and custodial fees;

taxes;

independent directors' fees and expenses;

marketing and distribution-related expenses;

the costs of any reports, proxy statements or other notices to stockholders, including printing and postage costs;

our allocable portion of the fidelity bond, directors and officers/errors and omissions liability insurance, and any other insurance premiums;

organization and offering; and

all other expenses incurred by us or Apollo Administration in connection with administering our business, such as our allocable portion of overhead under the administration agreement, including rent and our allocable portion of the cost of our chief financial officer and chief compliance officer and their respective staffs.

The SEC requires that "Total annual expenses" be calculated as a percentage of net assets in the chart on page S-1 rather than as a percentage of total assets. Total assets includes net assets as of June 30, 2008, anticipated net proceeds from this offering and assets that have been funded with borrowed monies (leverage). For reference, the below chart illustrates our "Total annual expenses" as a percentage of total assets:

Our interest and other credit facility expenses are based on current fiscal year estimates. We currently have $1.7 billion available under our credit facility, of which we had $0.97 billion in borrowings outstanding as of June 30, 2008. For more information, see "Risk Factors—We fund a portion of our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us." in the accompanying base prospectus and "Interim Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in this prospectus supplement.

Portfolio and Investment Activity

S-14

Since our initial public offering in April 2004 and through June 30, 2008, total invested capital exceeds $5.3 billion in 118 portfolio companies. Over the same period, we have also completed transactions with 81 different financial sponsors.

Senior secured loans and European mezzanine loans typically accrue interest at variable rates determined on the basis of a benchmark: LIBOR, EURIBOR, GBP LIBOR, or the prime rate, with stated maturities at origination that typically range from 5 to 10 years. While subordinated debt issued within the United States will typically accrue interest at fixed rates, some of these investments may include zero-coupon, PIK and/or step bonds that accrue income on a constant yield to call or maturity basis. At June 30, 2008, 60% or $1.7 billion of our interest-bearing investment portfolio is fixed rate debt and 40% or $1.1 billion is floating rate debt. At June 30, 2007, 66% or $1.6 billion of our interest-bearing investment portfolio was fixed rate debt and 34% or $830.7 million was floating rate debt.

CRITICAL ACCOUNTING POLICIES

Valuation of Portfolio Investments

(2) preliminary valuation conclusions are then documented and discussed with senior management of our investment adviser;

S-15

Investments are valued utilizing a market approach, an income approach, or both approaches, as appropriate. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business). The income approach uses valuation techniques to convert future amounts (for example, cash flows or earnings) to a single present amount (discounted). The measurement is based on the value indicated by current market expectations about those future amounts. In following these approaches, the types of factors that we may take into account in fair value pricing our investments include, as relevant: available current market data, including relevant and applicable market trading and transaction comparables, applicable market yields and multiples, security covenants, call protection provisions, information rights, the nature and realizable value of any collateral, the portfolio company's ability to make payments, its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons of financial ratios of peer companies that are public, M&A comparables, the principal market and enterprise values, among other factors.

SFAS No. 157 classifies the inputs used to measure these fair values into the following hierarchy:

Level 1 : Quoted prices in active markets for identical assets or liabilities, accessible by us at the measurement date.

Level 3 : Unobservable inputs for the asset or liability.

Revenue Recognition

S-16

recorded as interest income. We record prepayment premiums on loans and securities as interest income when we receive such amounts.

Net Realized Gains or Losses and Net Change in Unrealized Appreciation or Depreciation

Within the context of these critical accounting policies, we are not currently aware of any reasonably likely events or circumstances that would result in materially different amounts being reported.

RESULTS OF OPERATIONS

Results comparisons are for the three months ended June 30, 2008 and June 30, 2007.

Investment Income

For the three months ended June 30, 2008 and June 30, 2007, gross investment income totaled $91.0 million and $88.9 million, respectively. The increase in gross investment income for the three months ended June 30, 2008 was primarily due to the growth of our investment portfolio as compared to the previous period. Origination, closing and/or commitment fees associated with investments in portfolio companies are accreted into interest income over the respective terms of the applicable loans.

Expenses

Net expenses totaled $44.6 million and $34.2 million, respectively, for the three months ended June 30, 2008 and June 30, 2007, of which $11.6 million and $10.8 million, respectively, were performance-based incentive fees and $13.9 million and $7.6 million, respectively, were interest and other credit facility expenses. Net expenses exclusive of performance-based incentive fees and interest and other credit facility expenses for the three months ended June 30, 2008 and June 30, 2007 were $19.2 million and $15.7 million, respectively. Of these expenses, general and administrative expenses totaled $3.1 million and $2.8 million, respectively, for the three months ended June 30, 2008 and 2007. Expenses consist of base investment advisory and management fees, insurance expenses, administrative services fees, professional fees, directors' fees, audit and tax services expenses, and other general and administrative expenses. The increases in net expenses from the three month period ended June 30, 2007 to the three month period ended June 30, 2008 were primarily related to increases in base management fees and other general and administrative expenses from the growth of our investment portfolio as compared to the previous periods.

Net Investment Income

Our net investment income totaled $46.3 million and $54.8 million or $0.35 per share and $0.53 per share, respectively, for the three months ended June 30, 2008 and June 30, 2007, respectively.

Net Realized Gains (Losses)

We had investment sales and prepayments totaling $89.1 million and $346.9 million, respectively, for the three months ended June 30, 2008 and 2007. Net realized losses for the three months ended June 30, 2008 and June 30, 2007 were $29.8 million and $20.7 million, respectively. During the three months ended June 30, 2008, losses were derived primarily from the sale of American Asphalt which realized a loss of $26.0 million, reversing an unrealized loss of $25.4 million as of March 31, 2008.

Net Unrealized Appreciation (Depreciation) on Investments, Cash Equivalents and Foreign Currencies

For the three months ended June 30, 2008 we recognized net unrealized appreciation on its investments, cash equivalents, foreign currencies and other assets and liabilities totaling $55.3 million. For the three months ended June 30, 2007, net unrealized appreciation on our investments, cash equivalents, foreign

S-17

currencies and other assets and liabilities increased $143.7 million. At June 30, 2008, net unrealized depreciation totaled $141.8 million versus net unrealized appreciation of $235.9 million at June 30, 2007.

Net Increase (Decrease) in Net Assets From Operations

For the three months ended June 30, 2008, we had a net increase in net assets resulting from operations of $71.8 million. For the three months ended June 30, 2007 we had a net increase in net assets resulting from operations of $177.7 million. The net increase in net assets from operations per share was $0.55 for the three months ended June 30, 2008. For the three months ended June 30, 2007, the net increase in net assets from operations per share was $1.72.

LIQUIDITY AND CAPITAL RESOURCES

Our liquidity and capital resources are generated and available through periodic follow-on equity offerings, through its senior secured, multi-currency $1.7 billion, five-year, revolving credit facility maturing in April 2011, through investments in special purpose entities in which we hold and finance particular investments on a non-recourse basis, as well as from cash flows from operations, investment sales and prepayments of senior and subordinated loans and income earned from investments and cash equivalents. At June 30, 2008, the Company has $0.97 billion in borrowings outstanding and $0.73 billion remaining unused. In the future, we may raise additional equity or debt capital off its shelf registration or may securitize a portion of its investments among other considerations. The primary use of funds will be investments in portfolio companies, cash distributions to our stockholders and for other general corporate purposes. On May 16, 2008, we closed on its most recent follow-on public equity offering of 22.3 million shares of common stock at $17.11 per share raising approximately $369.6 million in net proceeds.

(1)	At June 30, 2008, $734 million remained unused under our senior secured revolving credit facility. Pricing of our credit facility is 100 basis points over LIBOR.

Contractual Obligations

Off-Balance Sheet Arrangements

We have the ability to issue standby letters of credit through its revolving credit facility. As of June 30, 2008 and June 30, 2007, we had issued through JPMorgan Chase Bank, N.A. standby letters of credit totaling $14.435 thousand and $0, respectively.

S-18

On May 20, 2008, the Company provided a $90 million commitment to Clothesline Holdings, Inc. and Clothesline Acquisition Corporation (entities owned and controlled by Lehman Brothers Merchant Banking Partners IV L.P.) to purchase a tranche of senior subordinated notes to fund a portion of the acquisition by way of merger (the "Acquisition") of Angelica Corporation ("Angelica"). The Acquisition is subject to certain conditions including the required approval of the Acquisition by Angelica's shareholders. Our commitment expires on the earlier of (i) the closing of the Acquisition, (ii) the abandonment or the termination of the Acquisition or (iii) 5:00 p.m. on September 30, 2008.

AIC Credit Opportunities Fund LLC. We own all of the common member interests in AIC Credit Opportunity Fund LLC, ("AIC Holdco") which was formed for the purpose of holding various financed investments. Effective in June 2008, we invested $39.5 thousand in a special purpose entity wholly owned by AIC Holdco, AIC (FDC) Holdings LLC ("Apollo FDC"), which was used to purchase a Junior Profit-Participating Note due 2013 in principal amount of $39.5 thousand (the "Junior Note") from Apollo I Trust (the "Trust"). The Trust also issued a Senior Floating Rate Note due 2013 (the "Senior Note") to an unaffiliated third party ("FDC Counterparty") in principal amount of $39.5 thousand paying interest at Libor plus 1.50%, increasing over time to Libor plus 2.0%. The Trust used the aggregate $79.0 thousand proceeds to acquire $100 thousand face value of a senior subordinated interim loan of First Data Corporation (the " First Data Reference Obligation"). The Junior Note generally entitles Apollo FDC to the net interest and other proceeds due under the FDC Reference Obligation after payment of interest due under the Senior Notes, as described above. In addition, Apollo FDC is entitled to 100% of any realized appreciation in the FDC Reference Obligation and, since the Senior Note is a non-recourse obligation, is exposed up to the amount of equity used by AIC Holdco to fund the purchase of the Junior Note plus any additional margin Apollo FDC decides to post, if any, during the term of the financing.

Through AIC Holdco, effective in June 2008, we also invested $11.375 thousand in a special purpose entity, AIC (TXU) Holdings LLC ("Apollo TXU") which acquired exposure to $50.0 thousand notional amount of a Libor plus 3.5% senior secured delayed draw term loan of Texas Competitive Electric Holdings ("TXU") through a non-recourse total return swap with an unaffiliated third party expiring on October 10, 2013 and pursuant to which Apollo TXU pays interest at Libor plus 1.5% and generally receives all proceeds due under the delayed draw term loan of TXU (the "TXU Reference Obligation"). Like Apollo FDC, Apollo TXU is entitled to 100% of any realized appreciation in the TXU Reference Obligation and, since the total return swap is a non-recourse obligation, is exposed up to the amount of equity used by AIC Holdco to fund the investment in the total return swap, plus any additional margin Apollo TXU decides to post, if any, during the term of the financing.

Pursuant to applicable investment company accounting, we do not consolidate AIC Holdco or either of Apollo FDC or Apollo TXU and accordingly only the value of our investments in them is included on our balance sheet. The Senior Note and total return swap are non-recourse to AIC Holdco, its subsidiaries and Apollo Investment and have standard events of default including failure to pay contractual amounts when due and failure by each of the underlying Apollo counterparties to provide additional credit support if the value of the FDC Reference Obligation or the TXU Reference Obligation, as applicable, declines below specified levels. We may unwind either transaction at any time.

Dividends

Dividends paid to stockholders for the three months ended June 30, 2008 totaled $74.0 million or $0.52 per share versus $52.8 million or $0.51 per share for the three months ended June 30, 2007. Tax characteristics of all dividends will be reported to stockholders on Form 1099 after the end of the calendar year.

We intend to continue to distribute quarterly dividends to our stockholders. Our quarterly dividends, if any, will be determined by our board of directors.

We have elected to be taxed as a RIC under Subchapter M of the Internal Revenue Code of 1986. To maintain our RIC status, we must distribute at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of the assets legally available for distribution. In addition, although we currently intend to distribute realized net capital gains (i.e., net long-term capital gains in excess of short-term capital losses), if any, at least annually, out of the assets legally available for such distributions, we may in the future decide to retain such capital gains for investment.

S-19

With respect to the dividends paid to stockholders, income from origination, structuring, closing, commitment and other upfront fees associated with investments in portfolio companies is treated as taxable income and accordingly, distributed to stockholders. For the three months ended June 30, 2008 and June 30, 2007 we received upfront fees totaling $0.0 million and $0.1 million, respectively, which are being amortized into income over the lives of their respective loans to the extent such loans remain outstanding.

QUANTITATIVE AND QUALITATIVE DISCLOSURES

ABOUT MARKET RISK

We are subject to financial market risks, including changes in interest rates. During the three months ended June 30, 2008, many of the loans in our portfolio had floating interest rates. These loans are usually based on a floating LIBO rate and typically have durations of one to six months after which they reset to current market interest rates. As the percentage of our U.S. mezzanine and other subordinated loans increase as a percentage of our total investments, we expect that more of the loans in our portfolio will have fixed rates. Accordingly, we may hedge against interest rate fluctuations by using standard hedging instruments such as futures, options and forward contracts subject to the requirements of the 1940 Act. While hedging activities may insulate us against adverse changes in interest rates, they may also limit our ability to participate in the benefits of lower interest rates with respect to our portfolio of investments. During the three months ended June 30, 2008, we did not engage in interest rate hedging activities.

The following table is designed to illustrate the effect on return to a holder of our common stock of the leverage created by our use of borrowing and potential issuance of preferred stock, at the weighted average annual interest rate of _____% for the_________ months ended ______________, 200_,and assuming the same average dividend rate on any preferred stock that we might issue and hypothetical annual returns on our portfolio of minus 10 to plus 10 percent. As can be seen, leverage generally increases the return to stockholders when the portfolio return is positive and decreases the return when the portfolio return is negative. Actual returns may be greater or less than those appearing in the table.

Assumed return on portfolio (net of expenses) (1)	-10.0%	-5.0%	0%	5.0%	10.0%

Corresponding Return to Common Stockholders (2)	-%	-%	-%	%	%

________________________________

(1) The assumed portfolio return is required by regulation of the SEC and is not a prediction of, and does not represent, our projected or actual performance.

(2) In order to compute the "Corresponding Return to Common Stockholders," the "Assumed Return on Portfolio" is multiplied by the total value of our assets at the beginning of the period to obtain an assumed return to us. From this amount, all interest expense accrued during the period is subtracted to determine the return available to stockholders. The return available to stockholders is then divided by the total value of our net assets as of the beginning of the period to determine the "Corresponding Return to Common Stockholders."

UNDERWRITING

________________________ are acting as joint bookrunning managers of the offering and as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus, each underwriter named below has agreed to purchase, and we have agreed to sell to that underwriter, the number of shares set forth opposite the underwriter's name.

Underwriter		Number of Shares

The underwriting agreement provides that the obligations of the underwriters to purchase the shares included in this offering are subject to certain conditions precedent, including the absence of any material adverse change in our business and the receipt of certain certificates, opinions and letters from us, our counsel and our independent registered public accounting firm. The underwriters are committed to purchase all shares included in this offering, other than those shares covered by the over-allotment option described below, if they purchase any of the shares.

The underwriters propose to offer some of the shares directly to the public at the public offering price set forth on the cover page of this prospectus and some of the shares to dealers at the public offering price less a concession not to exceed $_____ per share. If all of the shares are not sold at the initial offering price, the representatives may change the public offering price and the other selling terms.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to ________ additional shares of common stock at the public offering price less the underwriting discount. The underwriters may exercise the option solely for the purpose of covering over-allotments, if any, in connection with this offering. To the extent the option is exercised, each underwriter will be obligated, subject to certain conditions, to purchase a number of additional shares approximately proportionate to that underwriter's initial purchase commitment.

We, our officers and directors, Apollo Investment Management, Apollo Investment Administration LLC and certain of the partners and officers of Apollo Investment Management (or any entities through which such partners and officers may invest in our shares) have agreed that, for a period of 90 days from the date of this prospectus, we and they will not, without the prior written consent of the representatives, dispose of or hedge any shares of our common stock or any securities convertible into or exchangeable for our common stock. _____________ in its sole discretion may release any of the securities subject to these lock-up agreements at any time without notice. Notwithstanding the foregoing, for the purpose of allowing the underwriters to comply with NASD Rule 2711(f)(4), if (1) during the last 17 days of the initial 90-day lock-up period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the initial 90-day lock-up period, we announce that we will release earnings results during the 16-day period beginning on the last day of the initial 90-day lock-up period, then in each case the initial 90-day lock-up period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable.

The common stock is quoted on the Nasdaq Global Select Market under the symbol "AINV".

S-22

European Economic Area

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive, each underwriter has represented and agreed that, with effect from and including the date on which the Prospectus Directive is implemented in that Member State, it has not made and will not make an offer of shares of our common stock to the public in that Member State except that it may, with effect from and including such date, make an offer of shares of our common stock to the public in that Member State:

at any time to legal entities which are authorized or registered to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities;

at any time to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000; and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or

at any time in any other circumstances which do not require the publication by us of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of the above, the expression an "offer of shares of our common stock to the public" in relation to any shares of our common stock in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the shares of our common stock to be offered so as to enable an investor to decide to purchase or subscribe for the shares of our common stock, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in that Member State.

United Kingdom

Each underwriter has represented and agreed that it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000) in connection with the issue or sale of the shares of our common stock in circumstances in which Section 21(1) of such Act does not apply to us and it has complied and will comply with all applicable provisions of such Act with respect to anything done by it in relation to any shares of our common stock in, from or otherwise involving the United Kingdom.

The Netherlands

Each underwriter has represented and agreed that the offer in The Netherlands of the shares included in this offering is exclusively limited to persons who trade or invest in securities in the conduct of a profession or business (which include banks, stockbrokers, insurance companies, pension funds, other institutional investors and finance companies and treasury departments of large enterprises).

The following table shows the sales load (underwriting discounts and commissions) that we are to pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional shares of common stock.

	Paid by Apollo Investment
	No exercise	Full exercise
Per share	$	$
Total	$	$

In connection with the offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. "Covered" short sales are sales of shares made

S-23

in an amount up to the number of shares represented by the underwriters' over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make "naked" short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress.

The underwriters may also impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when an underwriter repurchases shares originally sold by that syndicate member in order to cover syndicate short positions or make stabilizing purchases.

Any of these activities may have the effect of preventing or retarding a decline in the market price of the common stock. They may also cause the price of the common stock to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions on the Nasdaq Global Select Market or in the over-the-counter market, or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

In addition, in connection with this offering, some of the underwriters may engage in passive market making transactions in the common stock on the Nasdaq Global Select Market, prior to the pricing and completion of the offering. Passive market making consists of displaying bids on the Nasdaq Global Select Market no higher than the bid prices of independent market makers and making purchases at prices no higher than those independent bids and effected in response to order flow. Net purchases by a passive market maker on each day are limited to a specified percentage of the passive market maker's average daily trading volume in the common stock during a specified period and must be discontinued when that limit is reached. Passive market making may cause the price of the common stock to be higher than the price that otherwise would exist in the open market in the absence of those transactions. If the underwriters commence passive market making transactions, they may discontinue them at any time.

We estimate that our portion of the total expenses of this offering will be $________. [In addition, the underwriters have agreed to pay certain of our expenses associated with this offering.]

As described under "Use of Proceeds," we intend to use a part of the net proceeds from this offering to repay a portion of the borrowings outstanding under our senior credit facility. Affiliates of each of and certain of the other underwriters are lenders under such credit facility and therefore will receive a portion of the net proceeds from this offering through the repayment of those borrowings. Accordingly, this offering is being made pursuant to NASD Rule 2710(h).

The underwriters have performed investment banking and advisory services for us, AIM, and our affiliates from time to time for which they have received customary fees and expenses. The underwriters may, from time to time, engage in transactions with and perform services for us, AIM, and our affiliates in the ordinary course of their business.

A prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters. Other than the prospectus in electronic format, the information on any such underwriter's website is not part of this prospectus. The representatives may agree to allocate a number of shares to underwriters for sale to their online brokerage account holders. The representatives will allocate shares to underwriters that may make Internet distributions on the same basis as other allocations. In addition, shares may be sold by the underwriters to securities dealers who resell shares to online brokerage account holders.

S-24

We, AIM and AIA have agreed to indemnify the underwriters against, or reimburse losses arising out of, certain liabilities, including liabilities under the Securities Act of 1933, as amended or to contribute to payments the underwriters may be required to make because of any of those liabilities.

This offering is being conducted in accordance with Rule 2710 of the NASD Rules of Conduct.

LEGAL MATTERS

APOLLO INVESTMENT CORPORATION

NOTES TO FINANCIAL STATEMENTS (unaudited)

(in thousands except share and per share amounts)

Note 1. Organization

Apollo Investment Corporation ("Apollo Investment", the "Company", or "We"), a Maryland corporation organized on February 2, 2004, is a closed-end, non-diversified management investment company that has filed an election to be treated as a business development company ("BDC") under the Investment Company Act of 1940. In addition, for tax purposes we have elected to be treated as a regulated investment company, or RIC, under the Internal Revenue Code of 1986, as amended. Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in middle-market companies in the form of mezzanine and senior secured loans, each of which may include an equity component, and, to a lesser extent, by making direct equity investments in such companies.

Apollo Investment commenced operations on April 8, 2004 receiving net proceeds of $870,000 from its initial public offering selling 62 million shares of common stock at a price of $15.00 per share.

Note 2. Significant Accounting Policies

The significant accounting policies consistently followed by Apollo Investment are:

(a) Security transactions are accounted for on the trade date;

(b) Under procedures established by our Board of Directors, we value investments, including certain subordinated debt, senior secured debt and other debt securities with maturities greater than 60 days, for which market quotations are readily available, at such market quotations (unless they are deemed not to represent fair value). We typically obtain market quotations from at least two brokers or dealers (if available, otherwise from a principal market maker or a primary market dealer or other independent pricing service). We utilize mid-market pricing as a practical expedient for fair value unless a different point within the range is more representative. From time to time, we may also utilize independent third party valuation firms to assist us in determining fair value if and when such market quotations are deemed not to represent fair value. Investments purchased within 60 days of maturity are valued at cost plus accreted discount, or minus amortized premium, which approximates value. Debt and equity securities that are not publicly traded or whose market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of our Board of Directors. Such determination of fair values may involve subjective judgments and estimates.

(1) our quarterly valuation process begins with each portfolio company or investment being initially valued by the investment professionals responsible for the portfolio investment;

S-43

APOLLO INVESTMENT CORPORATION

NOTES TO FINANCIAL STATEMENTS (unaudited) (continued)

(in thousands except share and per share amounts)

(2) preliminary valuation conclusions are then documented and discussed with our senior management;

(3) independent valuation firms engaged by our board of directors conduct independent appraisals and review management’s preliminary valuations and their own independent assessment;

SFAS No. 157 classifies the inputs used to measure these fair values into the following hierarchy:

Level 1 : Quoted prices in active markets for identical assets or liabilities, accessible by the Company at the measurement date.

Level 3 : Unobservable inputs for the asset or liability.

(d) Interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis. Origination and/or commitment fees associated with debt investments in portfolio companies are accreted into interest income over the respective terms of the applicable loans. Upon the prepayment of a loan or

S-44

NOTES TO FINANCIAL STATEMENTS (unaudited) (continued)

(in thousands except share and per share amounts)

debt security, any prepayment penalties and unamortized loan origination and/or commitment fees are recorded as interest income. Structuring fees are recorded as other income when earned.

(e) Apollo Investment intends to comply with the applicable provisions of the Internal Revenue Code of 1986, as amended, pertaining to regulated investment companies to make distributions of taxable income sufficient to relieve it from substantially all Federal income taxes. Apollo Investment, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income. Apollo Investment will accrue excise tax on estimated excess taxable income as required.

(f) Bok and tax basis differences relating to stockholder dividends and distributions and other permanent book and tax differences are reclassified among the Company's capital accounts. In addition, the character of income and gains to be distributed is determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America.

(g) Dividends and distributions to common stockholders are recorded as of record date. The amount to be paid out as a dividend is determined by the Board of Directors each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, are distributed or deemed distributed at least annually.

(h) In accordance with Regulation S-X and the AICPA Audit and Accounting Guide for Investment Companies, the Company does not consolidate its interest in any company other than in investment company subsidiaries and controlled operating companies substantially all of whose business consists of providing services to the Company. Consequently, the Company does not consolidate special purpose entities through which it holds investments subject to financing with third parties. See note 6.

(l) The Company records registration expenses related to Shelf filings as prepaid assets. These expenses are charged as a reduction of capital upon utilization, in accordance with the AICPA Audit and Accounting Guide for Investment Companies.

(n) In June 2006, the Financial Accounting Standards Board issued FASB Interpretation No. ("FIN") 48, Accounting for Uncertainty in Income Taxes. FIN 48 is effective for financial statements issued for fiscal years beginning after December 15, 2006. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation requires recognition of the impact of a tax position if that position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In addition, FIN 48 provides measurement guidance whereby a tax position that meets the more-likely-than-not recognition threshold is calculated to determine the amount of benefit to recognize in the financial statements. The adoption of FIN 48 did not have a material impact on the Company's financial condition or results of operations. If the tax law requires interest and/or penalties to be paid on an underpayment of income taxes, interest and penalties will be classified as income taxes on our financial statements, if applicable.

(o) In February 2007, the Financial Accounting Standards Board ("FASB") issued SFAS 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment of FASB No. 115. This statement permits an entity to choose to measure many financial instruments and certain other items at fair value. This statement applies to all reporting entities, and contains financial statement presentation and disclosure requirements for assets and liabilities reported at fair value as a consequence of the election. This statement is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The Company did not elect fair value measurement for assets or liabilities other than portfolio investments, which are already measured at fair value, therefore, the adoption of this statement did not impact the Company's consolidated financial position or its results of operations.

For the three months ended June 30, 2008 and June 30, 2007, the Investment Adviser received $16,022 and $12,996, respectively, in base investment advisory and management fees and $11,578 and $10,835, respectively, in performance-based incentive fees from Apollo Investment.

For the three months ended June 30, 2008 and June 30, 2007, the Administrator was reimbursed $1,778 and $1,408, respectively, from Apollo Investment on the $1,868 and $1,461, respectively, of expenses accrued under the Administration Agreement.

On April 14, 2005, Apollo Investment entered into an $800,000 Senior Secured Revolving Credit Agreement (the "Facility"), among Apollo Investment, the lenders party thereto and JPMorgan Chase Bank, N.A. ("JPMorgan"), as administrative agent for the lenders. Effective December 29, 2005, lenders provided additional commitments in the amount of $100,000, increasing the total facility size to $900,000 on the same terms and conditions as the existing commitments. On March 31, 2006, Apollo Investment Corporation amended and restated its $900,000 senior secured, multi-currency, revolving credit facility due April 14, 2010. The amended Facility increased total commitments outstanding to $1,250,000 and extended the maturity date to April 13, 2011. The amended Facility also permits Apollo to seek additional commitments from new and existing lenders in the future, up to an aggregate amount not to exceed $2,000,000. In February 2007, Apollo Investment increased total commitments to $1,700,000 under the Facility with the same terms. Pricing remains at 100 basis points over LIBOR. The Facility is used to supplement Apollo's equity capital to make additional portfolio investments and for general corporate purposes. From time to time, certain of the lenders provide customary commercial and investment banking services to affiliates of Apollo Investment. JPMorgan also serves as custodian and fund accounting agent for Apollo Investment.

Note 4. Net Asset Value Per Share

At June 30, 2008, the Company's total net assets and net asset value per share were $2,264,903 and $15.93, respectively. This compares to total net assets and net asset value per share at March 31, 2008 of $1,897,908 and $15.83, respectively.

Effective in June 2008, we invested $39,500 in a special purpose entity wholly owned by AIC Holdco, AIC (FDC) Holdings LLC ("Apollo FDC"), which was used to purchase a Junior Profit-Participating Note due 2013 in principal amount of $39,500 (the "Junior Note") from Apollo I Trust (the "Trust"). The Trust also issued a Senior Floating Rate Note due 2013 (the "Senior Note") to an unaffiliated third party ("FDC Counterparty") in principal amount of $39,500 paying interest at Libor plus 1.50%, increasing over time to Libor plus 2.0%. The Trust used the aggregate $79,000 proceeds to acquire $100,000 face value of a senior subordinated interim loan of First Data Corporation (the " First Data Reference Obligation"). The Junior Note generally entitles Apollo FDC to the net interest and other proceeds due under the FDC Reference Obligation after payment of interest due under the Senior Notes, as described above. In addition, Apollo FDC is entitled to 100% of any realized appreciation in the FDC Reference Obligation and, since the Senior Note is a non-recourse obligation, is exposed up to the amount of equity used by AIC Holdco to fund the purchase of the Junior Note plus any additional margin Apollo decides to post, if any, during the term of the financing.

Through AIC Holdco, effective in June 2008, we also invested $11,375 in a special purpose entity, AIC (TXU) Holdings LLC ("Apollo TXU") which acquired exposure to $50,000 notional amount of a Libor plus 3.5% senior secured delayed draw term loan of Texas Competitive Electric Holdings ("TXU") through a non-recourse total return swap with an unaffiliated third party expiring on October 10, 2013 and pursuant to which Apollo TXU pays interest at Libor plus 1.5% and generally receives all proceeds due under the delayed draw term loan of TXU (the "TXU Reference Obligation"). Like Apollo FDC, Apollo TXU is entitled to 100% of any realized appreciation in the TXU Reference Obligation and, since the total return swap is a non-recourse obligation, is exposed up to the amount of equity used by AIC Holdco to fund the investment in the total return swap, plus any additional margin Apollo decides to post, if any, during the term of the financing.

Pursuant to applicable investment company accounting, we do not consolidate AIC Holdco or either of Apollo FDC or Apollo TXU and accordingly only the value of our investments in them is included on our balance sheet. The Senior Note and total return swap are non-recourse to AIC Holdco, its subsidiaries and the Company and have standard events of default including failure to pay contractual amounts when due and failure by each of the underlying Apollo counterparties to provide additional credit support if the value of the FDC Reference Obligation or the TXU Reference Obligation, as applicable, declines below specified levels. The Company may unwind either transaction at any time.

Note 12. Credit Agreement and Borrowings

Under the terms of the amended and restated Credit Agreement dated March 31, 2006 (the "Facility"), the lenders agreed to extend credit to Apollo Investment in an aggregate principal or face amount not exceeding $1,250,000 at any one time outstanding. The amended Facility also permits Apollo Investment to seek additional commitments from new and existing lenders in the future, up to an aggregate amount not to exceed $2,000,000. In February 2007, we increased total commitments to $1,700,000. The Facility is a five-year revolving facility (with a stated maturity date of April 14, 2011) and is secured by substantially all of the assets in Apollo Investment's portfolio, including cash and cash equivalents. Pricing is set at 100 basis points over LIBOR. The Facility contains affirmative and restrictive covenants, including: (a) periodic financial reporting requirements, (b) maintaining minimum stockholders' equity of the greater of (i) 40% of the total assets of Apollo Investment and its subsidiaries as at the last day of any fiscal quarter and (ii) the sum of (A) $400,000 plus (B) 25% of the net proceeds from the sale of equity interests in Apollo Investment after the closing date of the Facility, (c) maintaining a ratio of total assets, less total liabilities (other than indebtedness) to total indebtedness, in each case of Apollo Investment and its subsidiaries, of not less than 2.0:1.0, (d) maintaining minimum liquidity, (e) limitations on the incurrence of additional indebtedness, (f) limitations on liens, (g) limitations on investments (other than in the ordinary course of Apollo Investment's business), (h) limitations on mergers and disposition of assets (other than in the normal course of Apollo Investment's business activities) and (i) limitations on the creation or existence of agreements that permit liens on properties of Apollo Investment's subsidiaries. In addition to the asset coverage ratio described in clause (c) of the preceding sentence, borrowings under the Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that applies different advance rates to different types of assets in Apollo Investment's portfolio. The Facility currently provides for the ability of Apollo Investment to seek additional commitments from lenders in an aggregate amount of up to $300,000. The Facility is used to supplement Apollo Investment's equity capital to make additional portfolio investments and for other general corporate purposes.

The average debt outstanding on the credit facility was $882,775 and $580,209 for the fiscal years ended March 31, 2008 and 2007, respectively. The weighted average annual interest cost for the fiscal year ended March 31, 2008 was 5.96%, exclusive of 0.36% for commitment fees and for other prepaid expenses related to establishing the credit facility. The weighted average annual interest cost for the fiscal year ended March 31, 2007 was 5.48%, exclusive of 0.44% for commitment fees and for other prepaid expenses related to establishing the Facility. This weighted average annual interest cost reflects the average interest cost for all borrowings, including EURIBOR, CAD LIBOR, GBP LIBOR and USD LIBOR. The maximum amount borrowed during the three months ended June 30, 2008 and 2007 was $1,647,243 and $791,384, respectively, at value. The remaining capacity under the facility was $734,311 at June 30, 2008. At June 30, 2008, the Company was in compliance with all financial and operational covenants required by the Facility.

On May 20, 2008, the Company provided a $90,000 commitment to Clothesline Holdings, Inc. and Clothesline Acquisition Corporation (entities owned and controlled by Lehman Brothers Merchant Banking Partners IV L.P.) to purchase a tranche of senior subordinated notes to fund a portion of the acquisition by way of merger (the "Acquisition") of Angelica Corporation ("Angelica"). On July 29, 2008, Angelica's shareholders approved the Acquisition. On August 4, 2008, the transaction closed and we invested $60,000 in senior subordinated notes and $6,000 in common equity. An additional $25,000 of senior subordinated notes were syndicated to a third party.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Apollo Investment Corporation

We have reviewed the accompanying statements of assets and liabilities of Apollo Investment Corporation (the "Company") as of June 30, 2008 and March 31, 2008, including the schedules of investments, the related statements of operations for the three month periods ended June 30, 2008 and June 30, 2007, and of cash flows for the three month periods ended June 30, 2008 and June 30, 2007 and the statements of changes in net assets for the three month period ended June 30, 2008 and for the year ended March 31, 2008. These interim financial statements are the responsibility of the Company's management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the statement of assets and liabilities as of March 31, 2008, and the related statements of operations, of cash flows and of changes in net assets for the year then ended, and in our report dated May 28, 2008 we expressed an unqualified opinion on those financial statements. In our opinion, the information set forth in the accompanying statement of assets and liabilities as of March 31, 2008, is fairly stated in all material respects in relation to the financial statements from which it has been derived.

Our charter authorizes us, to the maximum extent permitted by Maryland law and subject to the requirements of the 1940 Act, to indemnify any present or former director or officer or any individual who, while a director or officer and at our request, serves or has served another corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner or trustee, from and against any claim or liability to which that person may become subject or which that person may incur by reason of his or her status as a present or former director or officer and to pay or reimburse their reasonable expenses in advance of final disposition of a proceeding. Our bylaws obligate us, to the maximum extent permitted by Maryland law and subject to the requirements of the 1940 Act, to indemnify any present or former director or officer or any individual who, while a director or officer and at our request, serves or has served another corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner or trustee and who is made a party to the proceeding by reason of his service in that capacity from and against any claim or liability to which that person may become subject or which that person may incur by reason of his or her status as a present or former director or officer and to pay or reimburse their reasonable expenses in advance of final disposition of a proceeding. The charter and bylaws also permit us to indemnify and advance expenses to any person who served a predecessor of us in any of the capacities described above and any of our employees or agents or any employees or agents of our predecessor. In accordance with the 1940 Act, we will not indemnify any person for any liability to which such person would be subject by reason of such person's willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

C-4

omission was unlawful. In addition, Maryland law permits a corporation to advance reasonable expenses to a director or officer upon the corporation's receipt of (a) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation and (b) a written undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.

The Investment Advisory and Management Agreement provides that, absent willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of the reckless disregard of its duties and obligations, Apollo Investment Management, L.P. (the "Adviser") and its officers, managers, agents, employees, controlling persons, members and any other person or entity affiliated with it are entitled to indemnification from the Apollo Investment for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of the Adviser's services under the Investment Advisory and Management Agreement or otherwise as an investment adviser of Apollo Investment.

The Administration Agreement provides that, absent willful misfeasance, bad faith or negligence in the performance of its duties or by reason of the reckless disregard of its duties and obligations, Apollo Investment Administration, LLC and its officers, manager, agents, employees, controlling persons, members and any other person or entity affiliated with it are entitled to indemnification from us for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of Apollo Investment Administration, LLC's services under the Administration Agreement or otherwise as administrator for Apollo Investment.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of Apollo Investment pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by us of expenses incurred or paid by a director, officer or controlling person of Apollo Investment in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
