We believe that the strength of the Company’s unique investment strategy – which focuses on acyclical “defensive growth” companies that are well researched by New Mountain Capital, L.L.C. (“New Mountain”), a leading alternative investment firm, is underscored by continued stable credit performance. The Company has had only seven portfolio companies, representing approximately $112 million of the cost of all investments made since inception in October 2008, or approximately 2.3% of $4.9 billion, go on non-accrual.


Robert Hamwee, CEO, commented: “The second quarter represented another solid quarter of performance for NMFC. We originated $258 million of investments, which fully deployed the proceeds from our April equity raise, and once again had no significant credit deterioration in the portfolio. Additionally, we continue to diversify our financing sources by issuing additional unsecured notes.”

“As managers and as significant stockholders personally, we are pleased with the completion of another successful quarter, where we fully earned our dividend and our book value continued to rise,” added Steven B. Klinsky, NMFC Chairman. “We believe our strategy of focusing on acyclical “defensive growth” industries and on companies that we know well continues to prove a successful strategy and preserves stockholder value.”

Portfolio and Investment Activity2

As of June 30, 2017, the Company’s NAV was approximately $1,031.3 million and its portfolio had a fair value of approximately $1,883.4 million in 81 portfolio companies, with a weighted average Yield to Maturity at Cost3 of approximately 10.8%. For the three months ended June 30, 2017, the Company made approximately $258.3 million of originations and commitments4. The $258.3 million includes approximately $154.9 million of investments in seven new portfolio companies and approximately $103.4 million of follow-on investments in nine portfolio companies held as of March 31, 2017. For the three months ended June 30, 2017, the Company had approximately $13.5 million of sales in three portfolio companies and cash repayments4 of approximately $182.1 million.

Consolidated Results of Operations

The Company’s total adjusted investment income for the three months ended June 30, 2017 and 2016 were approximately $50.0 million and $41.5 million, respectively. For the three months ended June 30, 2017 and 2016, the Company’s total adjusted investment income consisted of approximately $38.6 million5 and $34.5 million5 in cash interest income from investments, respectively, approximately $0.8 million and $0.9 million in payment-in-kind (“PIK”) interest income from investments, prepayment penalties of approximately $1.4 million and $3.3 million, respectively, net amortization of purchase premiums/discounts of approximately $1.8 million and $0.8 million, respectively, cash dividend income of approximately $0.2 million and $0.1 million, respectively, PIK and non-cash dividend income of approximately $4.8 million and $0.8 million, respectively, and approximately $2.4 million and $1.1 million in other income, respectively.

The Company’s total net expenses after income tax expense for the three months ended June 30, 2017 and 2016 were approximately $24.2 million and $19.7 million, respectively. Total net expenses after income tax expense for the three months ended June 30, 2017 and 2016 consisted of approximately $9.0 million and $6.8 million, respectively, of costs associated with the Company’s borrowings and approximately $13.3 million and $11.0 million, respectively, in net management and incentive fees. Since the initial public offering (“IPO”), the base management fee calculation has deducted the borrowings under the New Mountain Finance SPV Funding, L.L.C. credit facility (the “SLF Credit Facility”). The SLF Credit Facility had historically consisted of primarily lower yielding assets at higher advance rates. As part of an amendment to the Company’s existing credit facilities with Wells Fargo Bank, National Association, the SLF Credit Facility merged with and into the New Mountain Finance Holdings, L.L.C. credit facility (the “Holdings Credit Facility”) on December 18, 2014. Post credit facility merger and to be consistent with the methodology since the IPO, New Mountain Finance Advisers BDC, L.L.C. (the “Investment Adviser”) will continue to waive management fees on the leverage associated with those assets that share the same underlying yield characteristics with investments that were leveraged under the legacy SLF Credit Facility, which as of June 30, 2017 and 2016 totaled approximately $356.6 million and $269.6 million, respectively. For the three months ended June 30, 2017 and 2016, management fees waived were approximately $1.5 million and $1.3 million, respectively. The Investment Adviser cannot recoup management fees that the Investment Advisor has previously waived. The Company’s net direct and indirect professional, administrative, other general and administrative and income tax expenses for the three months ended June 30, 2017 and 2016 were approximately $1.9 million and $1.8 million, respectively.

For the three months ended June 30, 2017 and 2016, the Company recorded approximately $(26.4) million and $0.8 million of adjusted net realized (losses) gains, respectively, and $27.8 million and $22.0 million of adjusted net changes in unrealized appreciation (depreciation) of investments and securities purchased under collateralized agreements to resell, respectively. For the three months ended June 30, 2017 and 2016, benefit for taxes was approximately $0.1 million and $0.1 million, respectively, related to differences between the computation of income for United States (“U.S.”) federal income tax purposes as compared to accounting principles generally accepted in the United States (“GAAP”).


Liquidity and Capital Resources

As of June 30, 2017, the Company had cash and cash equivalents of approximately $36.3 million and total statutory debt outstanding of approximately $751.7 million7, which consisted of approximately $328.7 million of the $495.0 million of total availability on the Holdings Credit Facility, $122.5 million of the $122.5 million of total availability on the Company’s senior secured revolving credit facility (the “NMFC Credit Facility”), $155.5 million7 of convertible notes outstanding and $145.0 million of unsecured notes outstanding. Additionally, the Company had $126.7 million of SBA-guaranteed debentures outstanding as of June 30, 2017.

Portfolio and Asset Quality

The Company puts its largest emphasis on risk control and credit performance. On a quarterly basis, or more frequently if deemed necessary, the 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 materially in-line with expectations. Any investment performing materially below our expectations 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” could be moved to non-accrual status, and the final development could be an actual realization of a loss through a restructuring or impaired sale.

As of June 30, 2017, one portfolio company had an investment rating of “3”, with a total cost basis of approximately $36.8 million and a fair value of approximately $30.0 million.

As of June 30, 2017, two portfolio companies had an investment rating of “4”. The Company’s investments in these portfolio companies had an aggregate cost basis of approximately $27.3 million and an aggregate fair value of approximately $13.1 million.

Recent Developments

The Company has had approximately $98.3 million of originations and commitments since the end of the second quarter through August 4, 2017. This was offset by approximately $139.1 million of repayments and $2.5 million of sales during the same period.

On August 4, 2017, the Company’s board of directors declared a third quarter 2017 distribution of $0.34 per share payable on September 29, 2017 to holders of record as of September 15, 2017.

Use of Non-GAAP Financial Measures

In evaluating its business, NMFC considers and uses adjusted net investment income as a measure of its operating performance. Adjusted net investment income is defined as net investment income adjusted to reflect income as if the cost basis of investments held at NMFC’s IPO date had stepped-up to fair market value as of the IPO date. Under GAAP, NMFC’s IPO did not step-up the cost basis of the predecessor operating company’s existing investments to fair market value. Since the total value of the predecessor operating company’s investments at the time of the IPO was greater than the investments’ cost basis, a larger amount of amortization of purchase or issue discount, and different amounts in realized gains and unrealized appreciation, may be recognized under GAAP in each period than if a step-up had occurred. For purposes of the incentive fee calculation, NMFC adjusts income as if each investment was purchased at the date of the IPO (or stepped-up to fair market value). In addition, adjusted net investment income excludes any capital gains incentive fee.

The term adjusted net investment income is not defined under GAAP and is not a measure of operating income, operating performance or liquidity presented in accordance with GAAP. Adjusted net investment income has limitations as an analytical tool and, when assessing NMFC’s operating performance, and that of its portfolio companies, investors should not consider adjusted net investment income in isolation, or as a substitute for net investment income, or other consolidated income statement data prepared in accordance with GAAP. Among other things, adjusted net investment income does not reflect NMFC’s, or its portfolio companies’, actual cash expenditures. Other companies may calculate similar measures differently than NMFC, limiting their usefulness as comparative tools.


_________________________________

1   Adjusted net investment income is defined as net investment income adjusted to reflect income as if the cost basis of investments held at NMFC’s IPO date had stepped-up to fair market value as of the IPO date. Adjusted net investment income also excludes any capital gains incentive fee. For additional information regarding NMFC’s use of this non-GAAP financial measure, please refer to “Use of Non-GAAP Financial Measures”.
2 Includes collateral for securities purchased under collateralized agreements to resell.
3 References to “Yield to Maturity at Cost” assume the accruing investments in our portfolio as of a certain date, the "Portfolio Date", are purchased at cost on that date 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. Yield to Maturity at Cost uses the LIBOR curves at each quarter’s respective end date. The actual yield to maturity may be higher or lower due to the future selection of LIBOR contracts by the individual companies in the Company’s portfolio or other factors.
4 Excludes revolving credit facilities, payment-in-kind (“PIK”) interest, bridge loans, return of capital and realized gains / losses.
5 Includes reclassification into cash interest of recurring management fee from other income and recurring distributions from dividend income associated with NMFC Senior Loan Program I LLC, NMFC Senior Loan Program II LLC and our investments held by New Mountain Net Lease Corporation.
6 Under GAAP, the Company’s IPO did not step-up the cost basis of New Mountain Finance Holdings, L.L.C.’s (the “Predecessor Operating Company” or “NMF Holdings”) existing investments to fair market value at the IPO date. Since the total value of the Predecessor Operating Company’s investments at the time of the IPO was greater than the investments’ cost basis, a larger amount of amortization of purchase or original issue discount, as well as different amounts in realized gain and unrealized appreciation, may be recognized under GAAP in each period than if the step-up had occurred. This will remain until such predecessor investments are sold or mature in the future. The Company tracks the transferred (or fair market) value of each of its investments as of the time of the IPO and, for purposes of the incentive fee calculation, adjusts Pre-Incentive Fee Net Investment Income to reflect the amortization of purchase or original issue discount on the Company’s investments as if each investment was purchased at the date of the IPO, or stepped up to fair market value. This is defined as “Pre-Incentive Fee Adjusted Net Investment Income”. The Company also uses the transferred (or fair market) value of each of its investments as of the time of the IPO to adjust capital gains and losses (“Adjusted Realized Capital Gains (Losses)”) and unrealized capital appreciation and depreciation (“Adjusted Unrealized Capital Appreciation (Depreciation)”).
7 Includes premium received on additional convertible notes issued in September 2016.
