An arrangement by which the dividends or other earnings from an investment are used to buy additional shares in the investment vehicle.
A shareholder service that authorizes dividend and capital gain distributions to automatically purchase more fund shares. Taxes still must be paid on the amount reinvested even though no funds are received directly by the investor.
