Schedule of Effects of Movement in DLOM by Sensitivity Analysis by Using Basis Point Variations

The DLOM on our Springstone investment was 40% at December 31, 2022. In arriving at the DLOM, we started with a DLOM range based on the results of studies supporting valuation discounts for other transactions or structures without a public market. To select the appropriate DLOM within the range, we then considered many qualitative factors, including the percent of control, the nature of the underlying investee’s business along with our rights as an investor pursuant to the operating agreement, the size of investment, expected holding period, number of shareholders, access to capital marketplace, etc. To illustrate the effect of movements in the DLOM, we performed a sensitivity analysis below by using basis point variations (dollars in thousands):

Basis Point Change in Marketability Discount	Estimated Increase (Decrease) in Fair Value
+ 100 basis points	$	(43	)
- 100 basis points		43
