Portfolio and Investment Activity

During the three months ended September 30, 2008, we invested $225.8 million, across 5 new and 6 existing portfolio companies. This compares to investing $454.1 million in 7 new and 5 existing portfolio companies for the three months ended September 30, 2007. Investments sold or prepaid during the three months ended September 30, 2008 totaled $21.3 million versus $141.9 million for the three months ended September 30, 2007.

At September 30, 2008, our net portfolio consisted of 78 portfolio companies and was invested 23% in senior secured loans, 57% in subordinated debt, 4% in preferred equity and 16% in common equity and warrants versus 67 portfolio companies invested 24% in senior secured loans, 53% in subordinated debt, 6% in preferred equity and 17% in common equity and warrants at September 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 10.2%, 13.4% and 12.5%, respectively, at September 30, 2008. At September 30, 2007, the yields were 11.9%, 13.1%, and 12.7%, respectively.

Since the initial public offering of Apollo Investment Corporation in April 2004 and through September 30, 2008, total invested capital exceeds $5.5 billion in 123 portfolio companies. Over the same period, Apollo Investment has also completed transactions with 85 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 September 30, 2008, 66% or $1.8 billion of our interest-bearing investment portfolio is fixed rate debt and 34% or $0.9 billion is floating rate debt at value. At September 30, 2007, 58% or $1.5 billion of our interest-bearing investment portfolio was fixed rate debt and 42% or $1.1 billion was floating rate debt at value.

RESULTS OF OPERATIONS

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

Investment Income

For the three and six months ended September 30, 2008, gross investment income totaled $103.5 million and $194.5 million, respectively. For the three and six months ended September 30, 2007, gross investment income totaled $86.1 million and $175.0 million, respectively. The increase in gross investment income for the three and six months ended September 30, 2008 was primarily due to the growth of our investment portfolio as compared to the previous period. Origination 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 $47.1 million and $91.7 million, respectively, for the three and six months ended September 30, 2008, of which $30.5 million and $58.1 million, respectively, were base management fees and performance-based incentive fees and $14.4 million and $28.3 million, respectively, were interest and other credit facility expenses. Of these expenses, general and administrative expenses totaled $2.2 million and $5.3 million, respectively, for the three and six months ended September 30, 2008. Net expenses totaled $24.4 million and $58.6 million, respectively, for the three and six months ended September 30, 2007, of which $7.5 million and $31.3 million, respectively, were base management fees and performance-based incentive fees and $15.1 million and $22.7 million, respectively, were interest and other credit facility expenses. Of these expenses, general and administrative expenses totaled $1.8 million and $4.6 million, respectively, for the three and six months ended September 30, 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 and six month period ended September 30, 2007 to the three and six month period ended September 30, 2008 were primarily related to increases in base management and incentive fees and other general and administrative expenses from the growth of our investment portfolio as compared to the previous periods.

For the three and six months ended September 30, 2007, net unrealized appreciation on the Company's investments, cash equivalents, foreign currencies and other assets and liabilities decreased $83.9 million and increased $59.8 million, respectively. At September 30, 2008, net unrealized depreciation totaled $406.2 million versus net unrealized appreciation of $152.1 million at September 30, 2007.

For the three and six months ended September 30, 2007, there was a loss per share of $0.22 and earnings per share of $1.47, respectively.

LIQUIDITY AND CAPITAL RESOURCES

The Company's 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 of liquid assets and prepayments of senior and subordinated loans and income earned from investments and cash equivalents. At September 30, 2008, the Company has $1.66 billion in borrowings outstanding and $0.04 billion remaining unused. In the future, the Company 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, the Company 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. Cash and cash equivalents at September 30, 2008 totaled $411.2 million.

Dividends

Dividends paid to stockholders for the three and six months ended September 30, 2008 totaled $74.0 million or $0.52 per share and $147.9 million or $1.04 per share, respectively. For the three and six months ended September 30, 2007, dividends totaled $54.0 million or $0.52 per share and $106.8 million or $1.03 per share, respectively. Tax characteristics of all dividends will be reported to shareholders 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.

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.

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 business development company 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.
