First Quarter 2020 Dividend of $0.39 Per Share Declared
On February 12, 2020 our board of directors declared a regular quarterly dividend of $0.39 per share payable on March 27, 2020 to stockholders of record as of March 13, 2020.
When declaring dividends, our Board of Directors reviews estimates of taxable income available for distribution, which differs from consolidated income under generally accepted accounting principles due to (i) changes in unrealized appreciation and depreciation, (ii) temporary and permanent differences in income and expense recognition, and (iii) the amount of undistributed taxable income carried over from a given year for distribution in the following year. The final determination of 2020 taxable income, as well as the tax attributes for 2020 dividends, will be made after the close of the 2020 tax year. The final tax attributes for 2020 dividends will generally include ordinary taxable income but may also include capital gains, qualified dividends and return of capital.
