"At the Market" Stock Offering Program

In August 2015, the Company established an "at the market" stock offering program ("ATM Program") through which it may, from time to time, issue and sell cumulative shares of its common stock having an aggregate cumulative gross sales price of up to $500.0 million to or through sales agents. Sales, if any, under the ATM Program may be made by means of ordinary brokers' transactions on the New York Stock Exchange or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or, subject to specific instructions of the Company, at negotiated prices. The Company intends to use the net proceeds from any sales under the ATM Program for general corporate purposes, which may include the funding of future acquisitions or investments and the repayment or repurchase of any outstanding indebtedness. During the three months ended March 31, 2016, 3.8 million shares of common stock were sold under the ATM Program generating net proceeds of $323.8 million after giving effect to sales agent commissions of $3.3 million.
