We believe that the strength of the Operating Company’s unique investment strategy – which focuses on acyclical “defensive growth” companies that are well researched by New Mountain Capital, L.L.C., a leading private equity firm – is underscored by continued strong credit performance, including the fact that the Operating Company has had only one non-performing loan representing 0.3% of the cost of all investments made since its inception in October 2008.

“New Mountain continues to build our research capabilities and team strength over time,” commented Steven B. Klinsky, NMFC Chairman. “We believe this helps to drive the superior credit performance we have had at NMFC since its inception.”

Robert Hamwee, CEO, added “The second quarter was another strong one for the company, with Adjusted Net Investment Income reaching $0.35 per share, gross originations up at $126 million, and no adverse credit migration.”

Portfolio and Investment Activity

We are a holding company with no direct operations of our own, and our sole asset is our ownership in the Operating Company. We apply an investment company master-feeder structure whereby the financial results of the Operating Company are allocated to us based on our pro-rata ownership interest in the Operating Company.

The Operating Company is externally managed by its investment adviser, New Mountain Finance Advisers BDC, L.L.C. Both New Mountain Finance Corporation and the Operating Company have elected to be treated as business development companies under the Investment Company Act of 1940, as amended.

As of June 30, 2012, the Operating Company’s net asset value was approximately $427.7 million and its portfolio had a fair value of approximately $751.1 million in 56 portfolio companies, with a weighted average Unadjusted and Adjusted Yield to Maturity(1) of approximately 10.7% and 13.0%, respectively. For the three months ended June 30, 2012, the Operating Company made approximately $126.4 million of originations and commitments. The $126.4 million includes approximately $94.6 million of investments in five new portfolio companies and approximately $31.8 million of investments in four portfolio companies held as of March 31, 2012. For the three months ended June 30, 2012, the Operating Company had approximately $26.4 million of sales in five portfolio companies and repayments of approximately $104.4 million.

(1) “Adjusted Yield to Maturity’’ assumes that the investments in the Operating Company’s portfolio are purchased at fair value on June 30, 2012, held until their respective maturities with no prepayments or losses and are exited at par at maturity. This calculation excludes the impact of existing leverage, except for the non-recourse debt of New Mountain Finance SPV Funding, L.L.C (“NMF SLF”). NMF SLF is treated as a fully levered asset of the Operating Company, with NMF SLF’s net asset value being included for yield calculation purposes. The actual yield to maturity may be higher or lower due to the future selection of LIBOR contracts by the individual companies in the portfolio or other factors. References to “Unadjusted Yield to Maturity” have the same assumptions as Adjusted Yield to Maturity except that NMF SLF is not treated as a fully levered asset of the Operating Company, but rather the assets themselves are consolidated into the Operating Company.

Consolidated Results of Operations

The Operating Company’s total adjusted investment income for the three months ended June 30, 2012 was approximately $19.5 million. For the three months ended June 30, 2012, total adjusted investment income consisted of approximately $17.0 million in cash interest income from investments, prepayment penalties of approximately $1.1 million, approximately $0.6 million in payment-in-kind interest income from investments, net amortization of purchase premiums/discounts and origination fees of approximately $0.6 million and approximately $0.2 million in other income.


The Operating Company’s total net expenses for the three months ended June 30, 2012 were approximately $8.6 million, excluding $0.1 million of accrued hypothetical capital gains incentive fees. The hypothetical capital gains incentive fee is based upon the net adjusted realized capital gains and losses and the net adjusted unrealized capital appreciation and depreciation on a cumulative basis from inception through the end of the current period. Actual amounts paid to the Investment Adviser are consistent with the investment advisory and management agreement, as amended and restated, and are based only on actual net adjusted realized capital gains and losses computed net of adjusted unrealized capital depreciation on a cumulative basis from inception through the end of each calendar year. As of June 30, 2012, no actual capital gains incentive fee would be owed under the investment advisory and management agreement, as amended and restated, as cumulative adjusted net realized capital gains did not exceed cumulative adjusted unrealized depreciation.

Total net expenses for the three months ended June 30, 2012 consisted of approximately $2.4 million of costs associated with the Operating Company’s credit facilities and approximately $5.3 million in management and incentive fees, excluding the $0.1 million of capital gains incentive fees. The Operating Company has capped its direct and indirect expenses for the second year of operations at $3.5 million, resulting in professional fees, administrative expense, and other general and administrative expenses totaling approximately $0.875 million for the quarter ended June 30, 2012.

During the three months ended June 30, 2012, the Operating Company recorded approximately $7.5 million in adjusted net realized gains. During the three months ended June 30, 2012, the Operating Company also recorded approximately $(7.2) million in adjusted net change in unrealized appreciation (depreciation) of investments.

Liquidity and Capital Resources

As of June 30, 2012, the Operating Company had cash and cash equivalents of approximately $9.5 million, approximately $19.2 million of net unsettled securities payable and total debt outstanding of approximately $311.9 million (approximately $138.8 million of the $160.0 million of total availability of the Operating Company’s credit facility and $173.1 million of the $175.0 million of total availability of the NMF SLF’s credit facility).

On May 19, 2011, we priced our initial public offering of 7,272,727 shares of common stock at a public offering price of $13.75 per share. Concurrently with the closing of the initial public offering and at the public offering price of $13.75 per share, we sold an additional 2,172,000 shares of our common stock to certain executives and employees of, and other individuals affiliated with, New Mountain Capital (defined as New Mountain Capital Group, L.L.C. and its affiliates) in a separate private placement. The total gross proceeds raised in the offering were approximately $129.9 million.

On July 10, 2012, our shelf registration statement became effective. On July 17, 2012, we completed a public offering of 5,250,000 shares of our common stock at a public offering price of $14.35 per share for total gross proceeds of approximately $75.3 million. In connection with the offering, we granted the underwriters for the offering an option to purchase up to an additional 787,500 shares of common stock. Such option remains exercisable until August 11, 2012.

Portfolio and Asset Quality

The Operating Company puts its largest emphasis on risk control and credit performance. On a quarterly basis, or more frequently if deemed necessary, the Operating Company formally rates each portfolio investment on a scale of one to four. Each investment is assigned an initial rating of a “2” under the assumption that the investment is performing as expected. Any investment with consistently declining performances would be downgraded from the “2” rating to a “3” or a “4” rating, based on the deterioration of the investment. An investment rating of a “4” would be moved to non-accrual status, and the final development would be an actual crystallization of a loss through a restructuring or impaired sale. Since the inception of our credit business in October 2008, one investment has been assigned a rating of “4” and has been placed on non-accrual status. This investment has a cost basis of approximately $4.3 million and a fair value of approximately $0.3 million as of June 30, 2012.


Recent Developments

The Operating Company had approximately $81.3 million of originations and commitments in the first 39 days of the third quarter of 2012. This was offset by approximately $1.7 of sales and $19.9 million of repayments during the same period.
