The principal business address of each of the Reporting Persons is 787 Seventh Avenue, New York, NY 10019.
 
The Reporting Persons have entered into a joint filing agreement, dated as of May 31, 2011, a copy of which is attached to this Statement as Exhibit 99.1.
 
(d) – (e).  None of the Reporting Persons during the last five years has been convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors) or was party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which any such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
 
ITEM 3.                      SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
 
The Issuer was formed in connection with the initial public offering of the Issuer (the “IPO”). Prior to the IPO, the operations of the Issuer and its subsidiary (and all of the assets and liabilities related to such operations) were directly and indirectly owned by Guardian Partners and Guardian AIV.  Through a series of  formation transactions that were undertaken in connection with the IPO (the “Formation Transactions”), the Issuer became the owner of common membership units of New Mountain Finance Holdings, L.L.C., a Delaware limited liability company (the “Operating Company”), which owns all of such operations (and all of the assets and liabilities related to such operations).  Immediately after the Formation Transactions were completed and prior to the IPO, (i) Guardian Partners owned 1,252,964 shares of Common Stock and (ii) AIV Holdings owned 20,221,938 common membership units of the Operating Company, which are exchangeable at any time and from time to time in whole or in part, on a one-for-one basis into shares of Common Stock.
 
Simultaneously with the consummation of the IPO, the Issuer conducted a private placement of its shares of Common Stock (the “Private Placement”).  As part of the Private Placement, Mr. Klinsky acquired 1,794,412 shares of Common Stock and the Klinsky Trust acquired 68,965 shares of Common Stock.  All of the shares were acquired at a price of $13.75 per share. The shares of Common Stock acquired by Mr. Klinsky were acquired with personal funds and the shares of Common Stock acquired by the Klinsky Trust were acquired with trust funds.  As part of the Private Placement, Mr. Collins acquired 10,345 shares of New Mountain Finance Common Stock at a price of $13.75 per share with personal funds.
 
ITEM 4.                      PURPOSE OF TRANSACTION
 
Mr. Klinsky and the Klinsky Trust purchased the shares of Common Stock based on the belief that the shares of Common Stock, when purchased, represented an attractive investment opportunity.
 
New Mountain Finance Advisers BDC, L.L.C., a Delaware limited liability company (the “Investment Adviser”), is the investment advisor of the Operating Company.  Mr. Klinsky is the sole managing member of the sole member of the Investment Adviser. In addition, Mr. Klinsky is Chairman of the Board of Directors of the Issuer.  Accordingly, as a result of the relationships of the Reporting Persons to the Issuer, the Reporting Persons may, from time to time, consider various plans or proposals which are of the type enumerated in Item 4(a)-(j) of Schedule 13D.
 
In accordance with its limited partnership agreement, Guardian Partners intends to distribute the shares of Common Stock owned by it as promptly as reasonably practicable, as determined by Guardian GP in good faith, to its partners, and its limited partner will thereupon distribute such shares of Common Stock to its partners.  Depending on market conditions and subject to any applicable contractual or legal restrictions, AIV Holdings currently intends to exchange its common membership units of the Operating Company for shares of Common Stock and to sell such shares of Common Stock in an underwritten public offering or private sale.

The Issuer has adopted a dividend reinvestment plan (the “Dividend Reinvestment Plan”), which provides that if the Issuer’s board of directors declares a cash distribution to its stockholders, such cash distribution shall be automatically reinvested on behalf of the stockholders in additional shares of Common Stock (unless a stockholder opts out of such reinvestment), and the Issuer will automatically reinvest such cash in additional common membership units of the Operating Company.  The Issuer intends to make distributions to its stockholders out of assets legally available for distribution each quarter following the completion of the IPO.

Each of the Reporting Persons reserves the right, in light of its continuing analysis and discussions and its ongoing evaluation of the market price of the shares of Common Stock, business, prospects and financial condition of the Issuer, anticipated future developments concerning the Issuer, existing and anticipated market conditions from time to time, general economic and industry conditions, regulatory matters, its business objectives and other relevant factors and other opportunities available to the Reporting Persons, to formulate or change its plans and intentions at any time, as it deems appropriate. Without limiting the generality of the foregoing, any one or more of the Reporting Persons (and their respective affiliates) may (i) purchase or acquire (including through the exchange of common membership units of the Operating Company) additional shares of Common Stock or otherwise acquire beneficial ownership of shares of Common Stock, or sell or transfer shares of Common Stock through transactions in the open market, pursuant to private transactions (which may be with the Issuer or with third parties) or otherwise, (ii) distribute Common Stock in-kind to their partners or members, to the extent applicable, (iii) enter into privately negotiated derivative transactions with institutional counterparties to hedge the market risk of some or all of their positions in the Common Stock, and/or (iv) make proposals concerning or take any other action that might result in any transaction, event or action described in paragraphs (a) through (j) of Item 4 of the form of Schedule 13D promulgated under the Act.
 
ITEM 5.                      INTEREST IN SECURITIES OF THE ISSUER

Any common membership units of the Operating Company received by the Investment Adviser will be exchangeable on a one-for-one basis into shares of the Issuer but will be subject to a 3-year lock-up agreement, pursuant to which one-third of the common membership units received by the Investment Adviser will be released from the lock-up on an annual basis until the expiration of each 3-year lock-up period.  A more complete summary of the Investment Management Agreement is set forth in the Issuer’s Prospectus dated May 19, 2011, as filed with the SEC on May 23, 2011.  This summary is qualified in its entirety by the terms of the Investment Management Agreement, which is set forth as Exhibit 99.5.
