[1] Distributions are determined based on taxable income calculated in accordance with income tax regulations, which may differ from amounts determined under GAAP due to (i) changes in unrealized appreciation and depreciation, (ii) temporary and permanent differences in income and expense recognition, and (iii) the amount of spillover income carried over from a given tax year for distribution in the following tax year. The final determination of taxable income for each tax year, as well as the tax attributes for distributions in such tax year, will be made after the close of the tax year.
[2] Includes the impact of the different share amounts as a result of calculating per share data based on the weighted average basic shares outstanding during the period and certain per share data based on the shares outstanding as of a period end or transaction date. The issuance of common stock on a per share basis reflects the incremental net asset value changes as a result of the issuance of common stock in the Company’s continuous public offering and pursuant to the Company’s distribution reinvestment plan and the conversion of a portion of the 2031 Convertible Notes and the 2030 Convertible Notes to common stock.
[3] The total return equals the change in the ending market value over the beginning of period price per share plus distributions paid per share during the period, divided by the beginning price.
[4] Calculated by dividing (i) the lesser of purchases or sales of portfolio securities for the fiscal year by (ii) the monthly average of the value of portfolio securities owned by the Company during the fiscal year, with certain securities excluded from the numerator and denominator pursuant to applicable federal securities laws.
[5] During the years ended December 31, 2019, 2018 and 2017, the Advisor waived $1.8 million, $1.2 million and $0.1 million, respectively, of incentive fee.
[6] Calculated by dividing net debt investment purchases by the monthly average debt investment balance.
