Earnings Per Share [Abstract] |
Loss per Share of Common Stock | Loss per Share of Common Stock The following tables set forth the computation of basic and diluted loss per share of common stock for the three and nine months ended September 30, 2016 and 2015, respectively. We computed basic loss per share for the three and nine months ended September 30, 2016 and 2015, respectively, using the weighted average number of shares outstanding during the periods. Diluted loss per share for the three and nine months ended September 30, 2016 and 2015, reflects additional shares of common stock related to our convertible senior common stock (if the effect would be dilutive), that would have been outstanding if dilutive potential shares of common stock had been issued, as well as an adjustment to net income available to common stockholders as applicable to common stockholders that would result from their assumed issuance (dollars in thousands, except per share amounts).

(1) | We excluded 800,116 shares of convertible senior common stock from the calculation of diluted earnings per share for the three and nine months ended September 30, 2016, respectively, because it was anti-dilutive. We also excluded 828,444 shares and 791,582 shares of convertible senior common stock from the calculation of diluted earnings per share for the three and nine months ended September 30, 2015, respectively, because it was anti-dilutive.
