Earnings Per Share [Abstract]  
Income Per Share
Income Per Share
Beginning in the third quarter of 2011, the Company computes earnings per share under the two-class method, which is a method of computing earnings per share when an entity has both common stock and participating securities. Unvested restricted stock is considered a participating security because it contains rights to receive nonforfeitable dividends at the same rate as common stock. Under the two-class method, the calculation of basic and diluted earnings per common share excludes the income attributable to participating securities. Additionally, the weighted average shares outstanding exclude the impact of participating securities.
Historically, the Company computed earnings per share under the treasury stock method as the impact of participating securities did not change earnings per share prior to 2011.
The following table provides reconciliations of net earnings and shares used in calculating income per basic common share to those used in calculating income per diluted common share.
