Item 2.02. Results of Operations and Financial Condition

Set forth below are certain preliminary estimates of our financial condition and results of operations for the three months ended December 31, 2011. These estimates are subject to the completion of our financial closing procedures and are not a comprehensive statement of our financial results for the three months ended December 31, 2011. We advise you that our actual results may differ materially from these estimates as a result of the completion of our financial closing procedures, final adjustments and other developments arising between now and the time that our financial results for the three months ended December 31, 2011 are finalized.

Net investment income is estimated to have totaled between $0.28 and $0.31 per share for the three months ended December 31, 2011.

Net asset value as of December 31, 2011 is estimated to be between $14.50 and $14.55 per share.

We originated $164.1 million in new middle market investment commitments during the three months ended December 31, 2011. Approximately 38% of the new investment commitments were in unitranche loans, 29% were subordinated debt/second lien investments, 30% were senior secured loans and 3% were equity securities. Of the new investment commitments, $148.6 million funded at close. During the same period, sales of portfolio investments were $42.9 million. Overall, total investments in portfolio companies at fair value increased by $102.2 million during the three months ended December 31, 2011 after factoring in debt repayments.

As of December 31, 2011, we were in compliance with our asset coverage test.

We intend to announce final results of operations for the three months ended December 31, 2011 on February 6, 2012 after the close of the financial markets. We will host an earnings conference call on Tuesday, February 7, 2012 to discuss the quarterly financial results.

The preliminary financial data included herein have been prepared by, and is the responsibility of, management. McGladrey & Pullen, LLP, our independent registered public accounting firm, has not audited, reviewed, compiled or performed any procedures with respect to these preliminary estimates. Accordingly, McGladrey & Pullen, LLP does not express an opinion or any other form of assurance with respect thereto.

For purposes of determining our compliance with the asset coverage ratio test applicable to us as a business development company, we have agreed with the staff of the Securities and Exchange Commission, or SEC, to treat the outstanding notional amount of the total return swap, or TRS, between Golub Capital Master Funding LLC and Citibank, N.A. less the initial amount of any cash collateral required to be posted by us under the TRS, as a senior security for the life of that instrument. Further, for purposes of determining our compliance with the 70% qualifying assets requirement of the Investment Company Act of 1940, as amended, or 1940 Act, we have agreed to treat the TRS, as a whole, as a non-qualifying asset. We may, however, accord different treatment to the TRS in the future in accordance with any applicable new rules or interpretations adopted by the staff of the SEC.  Due to this treatment, our ability to incur additional debt or issue stock senior to our common stock will be limited because we are required to maintain asset coverage, as that term is defined in the 1940 Act, of at least equal to 200% immediately after each such issuance.
