The strength of New Mountain Finance Corporation’s unique investment strategy – which focuses on acyclical “defensive growth” companies well researched by New Mountain Capital, a leading private equity firm – is underscored by the Company’s book value of $13.98 per share as of June 30, 2011 (after reserving for the second quarter dividend) and the fact that the Company has had 0% defaults, non-performing loans or performance losses since its inception in October 2008.


“We are pleased that we have met or exceeded our guidance for our dividend, net investment income, credit quality and loss performance,” said Steven B. Klinsky, New Mountain Finance Corporation’s chairman. “We believe that our consistent and proven investment strategy has served and will continue to serve our investors well throughout various credit cycles. Our performance to date, including in the current volatile market conditions, is testament to the strength and resiliency of our differentiated approach.”

“Underwriting and credit performance have always been our highest priorities,” said Robert A. Hamwee, New Mountain Finance Corporation’s chief executive officer and president. “The recent economic and market uncertainty only serve to highlight how important our longstanding focus on acyclical, defensive industries and business models is.”

Portfolio and Investment Activity

New Mountain Finance Corporation is a holding company and its sole asset is its ownership in the Operating Company. We employ a master-feeder structure whereby the financial results of the Operating Company are allocated to us based on our pro-rata 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, 2011, our net asset value was $440.6 million and our portfolio had a fair value of approximately $544.3 million in 47 portfolio companies, with a weighted average Unadjusted and Adjusted Yield to Maturity1 of approximately 10.4% and 12.7%, respectively. For the three months ended June 30, 2011, the Operating Company made approximately $130.7 million of new investments in 10 portfolio companies. For the three months ended June 30, 2011, the Operating Company had approximately $42.2 million in debt repayments in existing portfolio companies, including full repayments due to the refinancing of two portfolio companies, and sales of approximately $10.3 million.

1 “Adjusted Yield to Maturity’’ assumes that the investments in the Operating Company’s portfolio are purchased at fair value on June 30, 2011 and 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

Total adjusted investment income for the three months ended June 30, 2011 was approximately $12.0 million. For the three months ended June 30, 2011, total adjusted investment income consisted of approximately $10.2 million in cash interest income from investments, approximately $0.9 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 $0.3 million in other income.


Total expenses for the three months ended June 30, 2011 were approximately $3.6 million. Total expenses consisted of approximately $1.5 million of costs associated with our credit facilities, approximately $1.3 million in management and incentive fees, approximately $0.5 million in professional fees, and approximately $0.3 million in administrative and other expense. The Operating Company has capped its direct and indirect expenses for the first year of operations at $3.0 million and therefore the total amount of professional fees, administrative expense, and other expense are $0.75 million for the quarter.

During the three months ended June 30, 2011, the Operating Company recorded $0.4 million in adjusted net realized losses mainly relating to partial pay-downs that occurred at par for investments valued at prices above par at the initial public offering date. During the three months ended June 30, 2011, the Operating Company recorded $0.6 million in adjusted net unrealized appreciation.

Liquidity and Capital Resources

As of June 30, 2011, the Operating Company had cash and cash equivalents of approximately $77.9 million, approximately $22.9 million of unsettled securities and total debt outstanding of approximately $161.2 million ($34.3 million of the $160.0 million of total availability of our Operating Company credit facility and approximately $126.9 million of the $175.0 million of total availability of our NMF SLF credit facility). Our total capacity for new investments as of June 30, 2011 was approximately $218.6 million after reserving for the payment of our second quarter 2011 dividend and net current liabilities.


On May 19, 2011, New Mountain Finance Corporation priced its 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 offering and at the public offering price of $13.75 per share, New Mountain Finance Corporation sold an additional 2,172,000 shares of its common stock to certain executives and employees of, and other individuals affiliated with, New Mountain Capital Group, L.L.C. in a separate private placement. The total gross proceeds raised in the offering were approximately $129.9 million.

Portfolio and Asset Quality

The Operating Company puts its largest emphasis on risk control and credit performance. At least quarterly, we formally have a process whereby we rate each asset on a scale of one to four. Each investment is originally assigned a rating of a “2.” Any investment with deteriorating performance would first be downgraded to a “3” or a “4”. Next, the asset 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. For both our current portfolio at June 30, 2011 and our cumulative investments since the inception of our credit business in October 2008, we have never migrated down the performance ladder to a “3” or “4” and had no material negative developments with any investment in our portfolio.

Recent Developments

The Operating Company had approximately $106.1 million of originations and commitments in the first 40 days of the third quarter of 2011, offset by approximately $8.0 million of prepayments.
