[1] Per share amounts are calculated using the weighted average shares outstanding during the period.
[2] Includes income tax (provision) benefit from realized gain on investments and net change in provision for deferred taxes on unrealized (appreciation) depreciation on investments.
[3] The continuous issuance of common stock may cause an incremental decrease in NAV per share due to the sale of shares at the then prevailing public offering price and the receipt of net proceeds per share by the Company less than NAV per share on each subscription closing date. The per share data was derived by computing (i) the sum of (A) the number of shares issued in connection with subscriptions and/or distribution reinvestment on each share transaction date multiplied by (B) the differences between the net proceeds per share and the NAV per share on each share transaction date, divided by (ii) the total shares outstanding during the period.
[4] The Manager agreed to reimburse the Company to the extent the per share price of the shares to the public, less underwriting fees, was less than net asset value per share.
[5] Represents the anti-dilutive impact on the NAV of the Company due to the repurchase of common shares.  See Note 11. Stockholders’ Equity.
[6] Represents the dilutive effect of issuing common stock below NAV per share during the period in connection with the satisfaction of the Company’s annual RIC distribution requirement and may include the impact of the different share amounts used for different items (weighted average basic common shares outstanding for the corresponding year and actual common shares outstanding at the end of the year) in the per common share data calculation and rounding impacts. See Note 13. Dividend.
[7] Ratios are not annualized.
[8] Total investment return is calculated assuming a purchase of common shares at the current market value on the first day and a sale at the current market value on the last day of the periods reported. Dividends and distributions, if any, are assumed for purposes of this calculation to be reinvested at prices obtained under the DRIP. Total investment return does not reflect brokerage commissions.
[9] Total investment return is calculated assuming a purchase of common shares at the current NAV on the first day and a sale at the current net asset value on the last day of the periods reported. Dividends and distributions, if any, are assumed for purposes of this calculation to be reinvested at prices obtained under the DRIP. Total investment return does not reflect brokerage commissions.
[10] Ratios are annualized. Incentive management fees included within the ratio are not annualized.
[11] Ratios are annualized, except for income taxes.
[12] Portfolio turnover rate is calculated using the lesser of year-to-date sales or year-to-date purchases over the average of the invested assets at fair value.
[13] Asset coverage ratio per unit is the ratio of the carrying value of our total consolidated assets, less all liabilities and indebtedness not represented by senior securities, to the aggregate amount of senior securities representing indebtedness. Asset coverage ratio per unit is expressed in terms of dollar amounts per $1,000 of indebtedness. Asset coverage ratio per unit does not include unfunded commitments. The inclusion of unfunded commitments in the calculation of the asset coverage ratio per unit would not cause us to be below the required amount of regulatory coverage.
