[1] All per share activity, excluding dividends, is calculated based on the weighted-average shares outstanding for the relevant period.
[2] Accretion (dilution) represents the effect of issuance of common stock and repurchase of treasury stock.
[3] Total return based on net asset value is calculated as the change in net asset value per share during the period plus dividends per share, divided by the beginning net asset values per share.
[4] Total return based on market value is calculated as the change in market value per share during the period plus dividends per share, divided by the beginning market value per share. For the periods 2021 and prior, total return based on market value is not applicable as the Company was not yet public for the entirety of the period.
[5] The ratio includes incentive fees and as incentive fees are performance driven, the amount expensed in future periods may vary significantly and is dependent on overall investment performance, early terminations, scheduled prepayments and other liquidity events.
[6] The ratios are calculated based on weighted average net assets for the relevant period.
[7] The portfolio turnover rate for the period is calculated by taking the lesser of investment portfolio purchases or sales during the period, divided by the average investment portfolio value during the period.
