Earnings Per Share [Abstract]  
Net Income (Loss) per Share
Net Income (Loss) per Share
Basic and diluted earnings per share are computed using the treasury stock method for second quarter and first six months 2017 and the two-class method for second quarter and first six months 2016. The two-class method is an earnings allocation formula that determines net income per share for each class of common stock and participating security. We previously determined that our 6.00% tangible equity units issued in 2013 were participating securities. In December 2016, we issued 7,857,000 shares of our common stock upon the mandatory settlement of the stock purchase contract related to the 6.00% tangible equity units. Per share amounts are computed by dividing earnings available to common shareholders by the weighted average shares outstanding during each period. In periods with a net loss, no such adjustment is made to earnings as the holders of the participating securities have no obligation to fund losses.
The computations of basic and diluted earnings per share are as follows:

We intend to settle the remaining principal amount of our 3.75% convertible senior notes due in 2020 (Convertible Notes) in cash upon conversion with only the amount in excess of par value of the Convertible Notes to be settled in shares of our common stock. Therefore, our calculation of diluted net income per share includes only the amount, if any, in excess of par value of the Convertible Notes. As such, the Convertible Notes have no impact on diluted net income per share until the price of our common stock exceeds the $24.49 conversion price of the Convertible Notes. The average price of our common stock in second quarter 2017 did not exceed the conversion price which resulted in no additional diluted outstanding shares.
