The final determination of the tax attributes for dividends each year are made after the close of the tax year.  The final tax attributes for 2018 dividends are currently expected to include ordinary taxable income, capital gains and qualified dividends.

Main Street maintains a dividend reinvestment plan (“DRIP”) that provides for the reinvestment of dividends on behalf of its registered stockholders who hold their shares with Main Street’s transfer agent and registrar, American Stock Transfer and Trust Company, or certain brokerage firms that have elected to participate in the DRIP.  Under the DRIP, if Main Street declares a dividend, registered stockholders (and stockholders holding shares through participating brokerage firms) who have not “opted out” of the DRIP by the dividend record date will have their dividend automatically reinvested into additional shares of Main Street common stock.
