Klinsky, the Steven B. Klinsky Trust and Adam J. Collins (collectively, the “Reporting Persons”)(1) with respect to the common membership units (“Units”), of New Mountain Finance Holdings, L.L.C., a Delaware limited liability company (the “Issuer”).  Capitalized terms used herein but not defined shall have the meanings ascribed thereto in the Schedule 13D.  Except as herein amended or supplemented, all other information in the Schedule 13D is as set forth therein.
Item 3.	Source and Amount of Funds or Other Consideration
Item 3 of the Schedule 13D is hereby amended to add the following: On June 21, 2013, New Mountain Finance Corporation (“NMFC”) completed an underwritten public offering of 2,000,000 shares of its Common Stock at a public offering price of $14.55 per share (the “June 2013 Primary Offering”). As a result, pursuant to the LLC Agreement as described in Item 6, NMFC used the aggregate net proceeds (after deducting underwriting discounts and commissions) from the June 2013 Primary Offering of $28,620,000 to acquire 2,000,000 Units. On June 21, 2013, NMFC completed an underwritten public offering of 4,000,000 shares of its Common Stock at a public offering price of $14.55 per share (the “June 2013 Resale Offering”) on behalf of AIV Holdings. In connection with the June 2013 Resale Offering, AIV Holdings tendered 4,000,000 Units held by AIV Holdings to NMFC in exchange for $56,440,000 of net proceeds (after deducting underwriting discounts and commissions) and NMFC issued 4,000,000 shares of its Common Stock directly to the underwriters for the June 2013 Resale Offering.  The underwriters for the June 2013 Resale Offering have a 30-day option to purchase up to an additional 900,000 shares of the NMFC’s Common Stock, which, if such option is exercised, would require AIV Holdings to tender a corresponding number of additional Units held by AIV Holdings to NMFC and instruct NMFC to issue such shares directly to the underwriters for the June 2013 Resale Offering.

As a result, pursuant to the LLC Agreement as described in Item 6, the Issuer issued 2,000,000 Units to NMFC in exchange for the net proceeds (after deducting underwriting discounts and commissions) of the June 2013 Primary Offering. On June 21, 2013, concurrent with the June 2013 Primary Offering, NMFC completed the June 2013 Resale Offering of 4,000,000 shares of its Common Stock at a public offering price of $14.55 per share on behalf of AIV Holdings. In connection with the June 2013 Resale Offering, AIV Holdings exchanged 4,000,000 Units held by AIV Holdings for 4,000,000 shares of the NMFC’s Common Stock and instructed NMFC to issue such shares directly to the underwriters for the June 2013 Resale Offering. The underwriters for the June 2013 Resale Offering have a 30-day option to purchase up to an additional 900,000 shares of the NMFC’s Common Stock, which, if such option is exercised, would require AIV Holdings to tender a corresponding number of additional Units held by AIV Holdings to NMFC and instruct NMFC to issue such shares directly to the underwriters for the June 2013 Resale Offering.
