On March 23, 2018, the Consolidated Appropriations Act of 2018, which includes the Small Business Credit Availability Act (the “Act”), was signed into law. The Act amends the Investment Company Act, as amended (the “1940 Act”) to permit a business development company (a “BDC”) to reduce the required minimum asset coverage ratio applicable to it from 200% to 150%, subject to certain requirements described therein.

On April 12, 2018, the board of directors (the “Board”) of New Mountain Finance Corporation (the “Company”), recommended the submission of a proposal for stockholders to approve the application of the 150% minimum asset coverage ratio to the Company at a Special Meeting of Stockholders.  

On the same day, the Board of the Company, including a “required majority” (as such term is defined in Section 57(o) of the Investment Company Act of 1940, as amended (the “1940 Act”)) of the Board, also approved the application of the modified asset coverage requirements set forth in Section 61(a)(2) of the 1940 Act, as amended by the Small Business Credit Availability Act. As a result, the Company’s asset coverage requirements for senior securities will be changed from 200% to 150%, effective April 12, 2019.  However, if the stockholder proposal is approved by the required votes of the Company’s stockholders at such Special Meeting of Stockholders, the Company would become subject to the 150% minimum asset coverage ratio the day after such stockholder approval instead of April 12, 2019.  

On April 18, 2018, New Mountain Finance Corporation issued a press release regarding the foregoing.  The press release is included as Exhibit 99.1 and incorporated herein by reference.
