Cash and Cash Equivalents [Abstract] |
Cash and Cash Equivalents | 9. CASH AND CASH EQUIVALENTS Cash equivalents represent cash in money market funds pending investment in longer-term portfolio holdings. Our portfolio may consist of temporary investments in U.S. Treasury Bills (of varying maturities), repurchase agreements, money market funds or repurchase agreement-like treasury securities. These temporary investments with original maturities of 90 days or less are deemed cash equivalents and are included in the Consolidated Schedule of Investments. At the end of each fiscal quarter, we may take proactive steps to preserve investment flexibility for the next quarter by investing in cash equivalents, which is dependent upon the composition of our total assets at quarter-end. We may accomplish this in several ways, including purchasing U.S. Treasury Bills and closing out positions on a net cash basis after quarter-end, temporarily drawing down on the Truist Credit Facility, or utilizing repurchase agreements or other balance sheet transactions as are deemed appropriate for this purpose. These amounts are excluded from average adjusted gross assets for purposes of computing the Investment Adviser’s management fee. U.S. Treasury Bills with maturities greater than 60 days from the time of purchase are valued consistent with our valuation policy. As of September 30, 2025 and 2024, cash and cash equivalents consisted of money market funds, and non-money market in the amounts of $30.7 million and $21.1 million and $38.8 million and $11.1 million at fair value, respectively.
