The weighted average yield on investments made during the third quarter at their current cost basis, as of Sept. 30, 2012, was 12.4 percent.

OPERATING RESULTS

Investment income

Total investment income for the three months ended Sept. 30, 2012, was $14.2 million compared with $10.3 million for the same period in the prior year. In the third quarter of 2012, total investment income consisted of $12.7 million in interest income on debt securities and cash (including $1.1 million of PIK interest and $1.2 million in prepayment premiums), $0.9 million of interest income on income-producing investments, as well as $0.6 million of other income, mainly related to fees from THL Credit Greenway Fund LLC (“Greenway”). This compares to $10.3 million of total investment income for the three months ended Sept. 30, 2011, which consisted of $9.0 million of interest income on debt securities and cash (including PIK interest of $0.6 million and $0.3 million of prepayment premiums), $0.6 million of interest income on income-producing investments and $0.7 million of other income, mainly related to fees from Greenway.

The increase in investment income compared to the same period in the prior year is due to the growth of THL Credit’s investment portfolio as well as higher prepayment premiums.

Operating expenses

Operating expenses for the three months ended Sept. 30, 2012 and 2011 were $5.8 million and $4.4 million, respectively. Base management fees for the same periods were $1.3 million and $1.0 million; incentive fees totaled $1.7 million and $1.4 million; administrator expenses were $0.7 million and $0.8 million; other expenses totaled $0.8 million and $0.7 million; and fees and expenses related to THL Credit’s credit facility totaled $1.3 million and $0.5 million, respectively.

The increase in base management fees and incentive fee expense is due to the growth in both the investment portfolio and net investment income. The increase in expenses and fees related to the credit facility is due to the level of borrowings and increased commitment size.

Net investment income

Net investment income totaled $8.5 million and $5.9 million, or $0.41 and $0.29 per share, based upon weighted average common shares outstanding for the three months ended Sept. 30, 2012 and 2011, respectively. The increase in net investment income compared to the same period in the prior year is due to the growth of THL Credit’s investment portfolio as well as higher prepayment premiums.

Net change in unrealized appreciation on investments

For the third quarter, THL Credit’s investment portfolio had a change in unrealized appreciation of ($1.7) million in 2012, compared to a change in unrealized appreciation of ($0.3) million in 2011. As of Sept. 30, 2012, and Dec. 31, 2011, net unrealized appreciation on investments was $1.8 million and $3.9 million, respectively.

The change in the net change in unrealized appreciation compared to the prior period was driven primarily by the reversal of $1.1 million in unrealized appreciation on liquidated investments, changes in the capital market conditions and in the financial performance of certain portfolio companies.

Realized and unrealized gain (loss) on interest rate derivative

For the third quarter, THL Credit’s interest rate derivative agreement, which was entered into on May 10, 2012, had unrealized depreciation of $0.5 million, which was due to capital markets changes impacting interest rate swap spreads. THL Credit also recognized a realized loss related to amounts paid on the interest rate derivate of $0.1 million.

Net increase in net assets resulting from operations

Net increase in net assets resulting from operations totaled $6.2 million and $5.6 million, or $0.30 and $0.28 per share based upon weighted average common shares outstanding, respectively, for the three months ended Sept. 30, 2012 and 2011, respectively.

This increase in net assets from operations is due to the continued growth in net investment income, which is a result of growing the portfolio, along with an increase in prepayment premiums.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

As of Sept. 30, 2012, THL Credit had cash of $25.9 million.

THL Credit’s liquidity and capital resources are derived from its revolving credit facility, term loan facility and cash flows from operations, including investment sales and repayments, and income earned. Its primary use of funds from operations includes making investments in portfolio companies, payment of dividends to stockholders and funding operating expenses it incurs. THL Credit used, and expects to continue to use, these capital resources, together with proceeds from the turnover within the portfolio and from future public and private offerings of securities to finance its investment objectives.

On Sept. 25, 2012, THL Credit received $81.7 million in net proceeds from a public equity offering of common stock. Proceeds were used to pay $46.1 million of outstanding loans on its revolving credit facility. THL Credit’s will use the remaining proceeds to make additional investments in portfolio companies and for general corporate purposes, including working capital requirements.

As of Sept. 30, 2012, THL Credit had $50.0 million outstanding under its term loan facility. There were no borrowings outstanding under the revolving credit facility as of Sept. 30, 2012.

As of Sept. 30, 2011, THL Credit had no borrowings outstanding under its revolving loan facility as it had borrowed and repaid $11.0 million during the nine months ended Sept. 30, 2011.

For the nine months ended Sept. 30, 2012, THL Credit’s operating activities used cash of $84.3 million primarily in connection with the purchase of investments, and its financing activities provided cash of $126.7 million from the net proceeds received from the public equity offering as well as net borrowings and used cash of $22.3 million for the payment of dividends to stockholders and financing costs related to the credit facility and term loan.
