On May 1, 2017, we completed an underwritten public offering of approximately 43.1 million shares (including the exercise of the underwriters’ 30-day option to purchase an additional 5.6 million shares) of our common stock, resulting in net proceeds of approximately $548 million, after deducting offering expenses.

During the six months ended June 30, 2016, we sold approximately 3 million shares of common stock under an at-the-market equity offering program, resulting in net proceeds of approximately $45 million, after deducting approximately $0.6 million of commissions. There is no availability under this equity offering program at June 30, 2017.
