Equity [Abstract] |
Earnings (Loss) per Common Share | Note 5. Earnings (Loss) per Common Share Basic earnings per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution that could occur if convertible securities, or other contracts to issue common stock, were exercised or converted into common stock. Dilutive securities are included in the calculation of diluted earnings per common share using the treasury stock method and the if-converted method in accordance with ASC Topic 260, “Earnings per Share.” Dilutive securities include the common stock equivalents of preferred stock, convertible notes, options granted pursuant to the Company’s stock option plans and outstanding restricted stock units and performance share units granted to employees and non-employee directors (see Note 13). There were no outstanding shares of the preferred stock at December 31, 2015 and 2014 (see Note 4), and no outstanding convertible notes at December 31, 2015. Weighted-average common shares outstanding—diluted is the same as weighted-average common shares outstanding—basic in periods when a net loss is reported or in periods when diluted earnings per share is higher than basic earnings per share. The following table summarizes the computation of basic and diluted earnings (loss) per share:

Earnings (loss) per share—diluted, reflects the potential dilution that could occur if convertible securities, or other contracts to issue common stock, were exercised or converted into common stock. Options with an exercise price in excess of the average market value of the Company's common stock during the period have been excluded from the calculation as their effect would be antidilutive. Antidilutive securities excluded from the earnings per share computation are summarized as follows:
• | For the year ended December 31, 2015, securities outstanding totaling approximately 10,812,000, including common shares underlying convertible senior notes of 10,248,000, in addition to antidilutive options and restricted stock.
• | For the year ended December 31, 2014, securities outstanding totaling approximately 16,000,000, including common shares underlying convertible senior notes of 15,000,000, in addition to anti-dilutive options and restricted stock.
• | For the year ended December 31, 2013, securities outstanding totaling approximately 25,029,000, including common shares underlying preferred stock of 4,293,000, and common shares underlying convertible senior notes of 15,000,000, in addition to antidilutive options and restricted stock.
