Common Stock

Common Stock Issuance

In July 2015, the Company completed the sale and issuance of 3,773,766 shares of its common stock at a price of $66.19 per share for aggregate gross proceeds of $249.8 million and aggregate net proceeds after offering costs of $249.6 million through a registered direct placement with an institutional investor.

In October 2014, the Company issued 351,476 shares of its common stock valued at approximately $21.6 million to partially fund a development acquisition (see Note 3 “Acquisitions” for additional information).

In September 2013, the Company completed an underwritten public offering of 6,175,000 shares of its common stock. The net offering proceeds, after deducting underwriting discounts and offering expenses, were approximately $295.9 million. We used a portion of the net proceeds from the offering to fund acquisitions, repay borrowings under the unsecured revolving credit facility, and for general corporate purposes.

At-The-Market Stock Offering Programs

Under our at-the-market stock offering programs, which commenced in July 2011 and December 2014, we may offer and sell shares of our common stock from time to time in “at-the-market” offerings. During the year ended December 31, 2014, the Company completed its existing at-the-market offering program (the “July 2011 At-The-Market Program”) under which we sold an aggregate of $200.0 million in gross sales price of shares, and in December 2014, we commenced a new at-the-market stock offering program (the “December 2014 At-The-Market Program”) under which we may offer to sell shares of our common stock with an aggregate gross sales price of up to $300.0 million. Since commencement of the December 2014 At-The-Market Program through December 31, 2015, we have sold 2,007,767 shares of common stock having an aggregate gross sales price of $150.1 million. As of December 31, 2015, shares of common stock having an aggregate gross sales price of up to $149.9 million remain available to be sold under this program. Actual future sales will depend upon a variety of factors, including but not limited to market conditions, the trading price of the Company’s common stock and our capital needs. We have no obligation to sell the remaining shares available for sale under this program.

The following table sets forth information regarding sales of our common stock under our at-the-market offering programs for the years ended December 31, 2015, 2014 and 2013:
