Dividend Reinvestment and Stock Purchase Plan
Dividend Reinvestment and Stock Purchase Plan	19. Dividend Reinvestment and Stock Purchase Plan In March 2011, we established a Dividend Reinvestment and Stock Purchase Plan, or the DRSPP, to provide our common stockholders, as well as new investors, with a convenient and economical method of purchasing our common stock and reinvesting their distributions. The DRSPP also allows our current stockholders to buy additional shares of common stock by reinvesting all or a portion of their distributions. The DRSPP authorizes up to 6,000,000 common shares to be issued. During 2014, we issued 3,527,166 shares and raised approximately $158.5 million under the DRSPP. During 2013, 1,449,139 shares and raised approximately $55.6 million under the DRSPP. During 2012, we issued 55,598 shares and raised approximately $2.2 million under the DRSPP. From the inception of the DRSPP through December 31, 2014, we have issued 5,091,508 shares and raised approximately $218.6 million. In 2013, we revised our DRSPP to pay for a majority of the plan-related fees, which were previously paid by investors, and to institute a waiver approval process, allowing larger investors or institutions, per a formal approval process, to purchase shares at a small discount, if approved by us. In 2014, we issued 3,330,556 shares and raised $150.0 million under the waiver approval process. In 2013, we issued 1,308,490 shares and raised $50.0 million under the waiver approval process. These shares are included in the total 2014 and 2013 activity noted in the preceding paragraph.
