Redemption of Preferred Stock In April 2017, we redeemed all of the 16,350,000 shares of our 6.625% Monthly Income Class F Preferred Stock, or the Class F preferred stock, for $25 per share, plus accrued dividends. We issued an irrevocable notice of redemption with respect to the Class F preferred stock in March 2017, and, as a result, we incurred a non-cash charge of $13.4 million for the first three months of 2017, representing the Class F preferred stock original issuance costs that we paid in 2012. C. Dividend Reinvestment and Stock Purchase Plan Our Dividend Reinvestment and Stock Purchase Plan, or our DRSPP, provides our common stockholders, as well as new investors, with a convenient and economical method of purchasing our common stock and reinvesting their distributions. Our DRSPP also allows our current common stockholders to buy additional shares of common stock by reinvesting all or a portion of their distributions. The DRSPP authorizes up to 26,000,000 common shares to be issued. During the first three months of 2018, we issued 45,933 shares and raised approximately $2.3 million under the DRSPP. During the first three months of 2017, we issued 966,557 shares and raised approximately $57.0 million under the DRSPP. From the inception of the DRSPP through March 31, 2018, we have issued 14,109,475 shares and raised approximately $664.2 million. Our DRSPP includes 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. We did not issue shares under the waiver approval process during the first three months of 2018. During the first three months of 2017, we issued 927,695 shares and raised $54.7 million under the waiver approval process. These shares are included in the total activity for the first three months of 2017 noted in the preceding paragraph. D. At-the-Market (ATM) Programs In September 2015, we established an “at-the-market” equity distribution program, or our ATM program, pursuant to which we can offer and sell up to 12,000,000 shares of common stock to, or through, a consortium of banks acting as our sales agents by means of ordinary brokers’ transactions on the NYSE at prevailing market prices or at negotiated prices. In October 2017, following the issuance and sale of the remaining shares under our prior ATM program, we established a new “at-the-market” equity distribution plan, or our new ATM program, and, together with our prior ATM program, our ATM programs, pursuant to which we are permitted to offer and sell up to 17,000,000 additional shares of common stock. We did not issue any shares under the ATM programs during the first three months of 2018 or 2017. From the inception of our ATM programs through March 31, 2018, we have issued 14,407,529 shares authorized by our ATM programs and raised $824.8 million.
