Control and Affiliate Investments
As required by the 1940 Act, the Company classifies its investments by level of control. “Control investments” are defined in the 1940 Act as investments in those companies that the Company is deemed to “control”. Under the 1940 Act, the Company is generally deemed to “control” a company in which it has invested if it owns 25% or more of the voting securities of such company or has greater than 50% representation on its board. “Affiliate investments” are investments in those companies that are “affiliated companies” of the Company, as defined in the 1940 Act, which are not control investments. The Company is deemed to be an “affiliate” of a company in which it has invested if it owns 5% or more, but generally less than 25%, of the voting securities of such company. “Non-control/non-affiliate investments” are investments that are neither control investments nor affiliate investments. For purposes of determining the classification of its investments, the Company has included consideration of any voting securities or board appointment rights held by the Adviser Funds.
The following table summarizes the Company’s realized gains and losses and changes in unrealized appreciation and depreciation on control and affiliate investments for the three and nine months ended September 30, 2026 and 2025.

(1)Effective September 30, 2026, the Company added the “Cybersecurity”, “Energy Technologies”, “Financial Technologies” and “Healthcare Technology & Digital Health” industry categories, which include investments previously classified within “Application Software”, “Consumer & Business Services”, “Healthcare Services, Other”, “Information Services”, “Sustainable and Renewable Technology” and “System Software”. Prior period amounts have been reclassified to conform to the current period presentation.
No single portfolio investment represents more than 10% of the fair value of the Company’s total investments as of September 30, 2026 or December 31, 2025.
Concentrations of Credit Risk
The Company’s customers are primarily privately held companies and public companies which are active in the “Application Software”, “Drug Discovery & Development”, “Healthcare Services, Other”, “Consumer & Business Services”, and “Defense Technologies” sectors. These sectors are characterized by high margins, high growth rates, consolidation and product and market extension opportunities. Value for companies in these sectors is often vested in intangible assets and intellectual property.
Industry and sector concentrations vary as new loans are recorded and loans are paid off. Investment income, consisting of interest, fees, and recognition of gains on equity and warrant or other equity interests, can fluctuate materially when a loan is paid off or a related warrant or equity interest is sold. Investment income recognized in any given year can be highly concentrated among several portfolio companies.
As of September 30, 2026 and December 31, 2025, the Company’s ten largest portfolio companies represented approximately 25.6% and 28.6%, respectively, of the total fair value of the Company’s investments in portfolio companies. As of September 30, 2026 and December 31, 2025, the Company had seven and seven portfolio companies, respectively, that represented 5% or more of the Company’s net assets. As of September 30, 2026, the Company had three equity investments which represented approximately 49.9% of the total fair value of the Company's equity investments, and each represented 5% or more of the total fair value of the Company’s equity investments. As of December 31, 2025, the Company had two equity investments which represented approximately 48.4% of the total fair value of the Company’s equity investments, and each represented 5% or more of the total fair value of the Company’s equity investments.
Investment Collateral
In the majority of cases, the Company collateralizes its investments by obtaining a first priority security interest in a portfolio company’s assets, which may include its intellectual property. In other cases, the Company may obtain a negative pledge covering a company’s intellectual property. The Company's investments were collateralized as follows as of September 30, 2026 and December 31, 2025:
