Statements other than statements of historical facts included in this Current Report on Form 8-K may constitute forward-looking statements and are not guarantees of future performance or results and involve a number of risks and uncertainties. Actual results may differ materially from those in the forward-looking statements as a result of a number of factors, including those described from time to time in filings with the Securities and Exchange Commission. The Company undertakes no duty to update any forward-looking statement made herein. All forward-looking statements speak only as of the date of this Current Report on Form 8-K.

On May 3, 2018, the board of directors (the “Board of Directors”) of the Company, including a “required majority” (as defined in Section 57(o) of the Investment Company Act of 1940, as amended (the “1940 Act”)) of the Board of Directors, approved the modified asset coverage requirements set forth in Section 61(a)(2) of the 1940 Act, as amended by the Consolidated Appropriations Act of 2018 (which includes the Small Business Credit Availability Act). The Board of Directors also approved the submission of a proposal for the Company’s stockholders to approve such modified asset coverage requirements at the Company’s 2018 annual meeting of stockholders. As a result, the Company’s asset coverage requirements applicable to senior securities are expected to decrease from 200% to 150%, effective May 3, 2019, unless earlier approved by a vote of a majority of the Company’s stockholders. In that case, the modified asset coverage requirements would be effective with respect to the Company the day after such stockholders’ approval.
