Equity Offering
20) Equity Offering

On July 1, 2015, we closed an underwritten registered public offering of common stock offered pursuant to a shelf registration statement on Form S-3 that was previously filed with, and declared effective by, the Securities Exchange Commission. The total number of shares of common stock sold was 7,590,000 at a public offering price of $24.00 per share. All of the shares in the offering were sold by us. Our net proceeds from the offering, after deducting underwriting discounts and commissions and offering expenses, were approximately $173.1 million. Of these proceeds, $148.7 million was used for repayment of principal and interest on our existing debt.
