Earnings Per Share

6 Months Ended

Jun. 30, 2013

Basic earnings per share are computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share are computed using the weighted average shares outstanding during the period, but also include the dilutive effect of awards of restricted stock, using the treasury stock method, and outstanding convertible preferred stock. Under the treasury stock method, the amount of unrecognized compensation expense related to unvested stock-based compensation grants are assumed to be used to repurchase shares at the average market price. The following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share, for the three and six-month periods ended June 30, 2013 and 2012 (in thousands):



	Three Months Ended June 30,		Six Months Ended June 30,
	2013	2012	2013	2012
Weighted average basic common shares outstanding	479,154	461,008	478,494	430,802
Effect of dilutive securities
Restricted stock	—	9,499	—	9,443
Convertible preferred stock	—	90,133	—	90,133
Weighted average diluted common and potential common shares outstanding	479,154	560,640	478,494	530,378

For the three and six-month periods ended June 30, 2013, restricted stock awards covering 194 and 3,585 shares, respectively, were excluded from the computation of loss per share because their effect would have been antidilutive.

In computing diluted earnings per share, the Company evaluated the if-converted method with respect to its outstanding convertible perpetual preferred stock for the three and six-month periods ended June 30, 2013 and 2012. Under the if-converted method, the Company assumes the conversion of the preferred stock to common stock and determines if this is more dilutive than including the preferred stock dividends (paid and unpaid) in the computation of income available (loss applicable) to common stockholders. For the three and six-month periods ended June 30, 2013, the Company determined the if-converted method was antidilutive and included the 8.5%, 6.0% and 7.0% preferred stock dividends in the determination of loss applicable to common stockholders. For the three and six-month periods ended June 30, 2012, the Company determined the if-converted method was more dilutive and did not include the 8.5%, 6.0% and 7.0% preferred stock dividends in the determination of income available to common stockholders.
