[1] Equity ownership may be held in shares or units of a company that is either wholly owned by the portfolio company or under common control by the same parent company to the portfolio company.

[2] Unless otherwise noted, all portfolio company headquarters are based in the United States.

[3] Affiliate investments are generally defined by the 1940 Act as investments in which between 5% and 25% of the voting securities are owned and the investments are not classified as control investments. At March 31, 2025, the Company held $292.9 million of affiliate investments, which represented approximately 16.4% of the Company’s investment assets. The fair value of these investments as a percent of net assets is 33.1%.

[4] All debt investments are income-producing, unless otherwise noted. Equity investments are non-income producing, unless otherwise noted.

[5] Control investments are generally defined by the 1940 Act as investments in which the Company owns more than 25% of the voting securities or has greater than 50% representation on its board. At March 31, 2025, the Company held $56.1 million of control investments, which represented approximately 3.1% of the Company's investment assets. The fair value of these investments as a percent of net assets is 6.3%. In accordance with Rules 3-09 and 4-08(g) of Regulation S-X, the Company must determine if its unconsolidated subsidiaries are considered "significant subsidiaries." As of March 31, 2025, there were no unconsolidated subsidiaries that are considered "significant subsidiaries."

[6] Non-Control/Non-Affiliate investments are generally defined by the 1940 Act as investments that are neither control investments nor affiliate investments.

The fair value of these investments as a percent of net assets is 162.6%.

[7] The Company's investment portfolio is comprised entirely of debt and equity securities of privately held companies for which quoted prices falling within the categories of Level 1 and Level 2 inputs are not readily available. Therefore, the Company values all of its portfolio investments at fair value, as determined in good faith by the valuation committee comprised of certain officers of the Company (the "Valuation Committee") as the valuation designee of the Board of Directors (the "Valuation Designee") pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended (the “1940 Act”), using significant unobservable Level 3 inputs.
