[8]	The Board of Directors considers all relevant information that can reasonably be obtained when determining the fair value of Level 3 investments. Due to any given portfolio company’s information rights, changes in capital structure, recent events, transactions, or liquidity events, the type and availability of unobservable inputs may change. Increases/(decreases) in revenue multiples, earnings before interest and taxes (“EBIT”) multiples, time to expiration, and stock price/strike price would result in higher (lower) fair values, all else equal. Decreases/(increases) in discount rates, volatility, and annual risk rates, would result in higher (lower) fair values, all else equal. The market approach utilizes market value (revenue and EBIT) multiples of publicly traded comparable companies and available precedent sales transactions of comparable companies. The Board of Directors carefully considers numerous factors when selecting the appropriate companies whose multiples are used to value the Company’s portfolio companies. These factors include, but are not limited to, the type of organization, similarity to the business being valued, relevant risk factors, as well as size, profitability and growth expectations. In general, precedent transactions include recent rounds of financing, recent purchases made by the Company, and tender offers. Refer to “Note 2—Significant Accounting Policies—Investments at Fair Value” for more detail.

[10]	As of December 31, 2025, the Board of Directors used a hybrid market and income approach to value certain common and preferred stock investments, as the Board of Directors felt this approach better reflected the fair value of these investments. In considering multiple valuation approaches (and consequently, multiple valuation techniques), the valuation approaches and techniques are not likely to change from one period of measurement to the next; however, the weighting of each in determining the final fair value of a Level 3 investment may change based on recent events or transactions. The hybrid approach may also consider certain risk weightings to account for the uncertainty of future events. Refer to “Note 2—Significant Accounting Policies—Investments at Fair Value” for more detail.
