Fair Value
In accordance with ASC 820, the fair value of our investments 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 March 31, 2026 and 2025, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investment in money market funds, which was valued using Level 1 inputs, and our investment in Gladstone Alternative Income Fund ("Gladstone Alternative"), 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. There were no transfers in or out of Level 1, 2 and 3 during the years ended March 31, 2026 and 2025, respectively.
As of March 31, 2026 and 2025, our investments, by security type, at fair value were categorized as follows within the ASC 820 fair value hierarchy:

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 or discount rates or a (decrease)/increase in EBITDA or EBITDA multiples (or revenue or revenue multiples) may result in a (decrease)/increase in the fair value of certain of our investments.

Receivables from Portfolio Companies

Receivables from portfolio companies represent non-recurring costs that we incurred on behalf of portfolio companies. Such receivables, net of any allowance for uncollectible receivables, are included in Other assets, net 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 March 31, 2026 and 2025, we had gross receivables from portfolio companies of $2.6 million and $2.3 million, respectively. As of March 31, 2026 and 2025, the allowance for uncollectible receivables was $1.4 million and $1.7 million, respectively.
