Investments, Debt and Equity Securities [Abstract] |
INVESTMENTS | INVESTMENTS In accordance with ASC 820, the fair value of each investment is determined to be the price that would be received for an investment in a current sale, which assumes an orderly transaction between willing market participants on the measurement date. This fair value definition focuses on exit price in the principal, or most advantageous, market and prioritizes, within a measurement of fair value, the use of market-based inputs over entity-specific inputs. ASC 820 also establishes the following three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of a financial instrument as of the measurement date. •Level 1 — inputs to the valuation methodology are quoted prices (unadjusted) for identical financial instruments in active markets; •Level 2 — inputs to the valuation methodology include quoted prices for similar financial instruments in active or inactive markets, and inputs that are observable for the financial instrument, either directly or indirectly, for substantially the full term of the financial instrument. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or instances where prices vary substantially over time or among brokered market makers; and •Level 3 — inputs to the valuation methodology are unobservable and significant to the fair value measurement. Unobservable inputs are those inputs that reflect assumptions that market participants would use when pricing the financial instrument and can include the Valuation Team’s assumptions based upon the best available information. When a determination is made to classify our investments within Level 3 of the valuation hierarchy, such determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, Level 3 financial instruments typically include, in addition to the unobservable, or Level 3, inputs, observable inputs (or components that are actively quoted and can be validated to external sources). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. Investments in funds measured using NAV as a practical expedient are not categorized within the fair value hierarchy. As of September 30, 2023, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investment in Funko Acquisition Holdings, LLC (“Funko”), which was valued using Level 2 inputs, and our investment in Leeds Novamark Capital I, L.P. (“Leeds”), which was valued using NAV as a practical expedient. As of September 30, 2022, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investment in Funko, which was valued using Level 2 inputs, and our investment in Leeds, which was valued using NAV as a practical expedient. We transfer investments in and out of Level 1, 2, and 3 of the valuation hierarchy as of the beginning balance sheet date, based on changes in the use of observable and unobservable inputs utilized to perform the valuation for the period. During the years ended September 30, 2023 and 2022, there were no investments transferred into or out of Levels 1, 2 or 3 of the valuation hierarchy. As of September 30, 2023 and 2022, our investments, by security type, at fair value were categorized as follows within the ASC 820 fair value hierarchy:

(A)Fair value as of September 30, 2022 includes one proprietary debt investment totaling $18.8 million, which was valued using the expected payoff amount as the unobservable input. (B)Fair value as of September 30, 2023 excludes our investments in Leeds and Funko with fair values of $0.2 million and $22 thousand, respectively. Fair value as of September 30, 2022 excludes our investments in Leeds and Funko with fair values of $6.4 million and $58 thousand, respectively. Leeds was valued using NAV as a practical expedient and Funko was valued using Level 2 inputs as of both September 30, 2023 and 2022. Fair value as of September 30, 2022 includes one syndicated equity investment totaling $8.0 million, which was valued using the expected payoff amount as the unobservable input. Fair value measurements can be sensitive to changes in one or more of the valuation inputs. Changes in discount rates, EBITDA or EBITDA multiples (or revenue or revenue multiples), each in isolation, may change the fair value of certain of our investments. Generally, an increase/(decrease) in market yields, discount rates, or a (decrease)/increase in EBITDA or EBITDA multiples (or revenue or revenue multiples) may result in a (decrease)/increase, respectively, in the fair value of certain of our investments. Changes in Level 3 Fair Value Measurements of Investments The following tables provide the changes in fair value, broken out by security type, during the years ended September 30, 2023 and 2022 for all investments for which we determine fair value using unobservable (Level 3) inputs.

Receivables from Portfolio Companies Receivables from portfolio companies represent non-recurring costs incurred on behalf of such portfolio companies and are included in other assets on our accompanying Consolidated Statements of Assets and Liabilities. We generally maintain an allowance for uncollectible receivables from portfolio companies when the receivable balance becomes 90 days or more past due or if it is determined, based upon management’s judgment, that the portfolio company is unable to pay its obligations. We write-off accounts receivable when we have exhausted collection efforts and have deemed the receivables uncollectible. As of September 30, 2023 and 2022, we had gross receivables from portfolio companies of $0.8 million and $0.5 million, respectively. The allowance for uncollectible receivables was $9 thousand and $0 as of September 30, 2023 and 2022, respectively.
