Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

We compute earnings per share using the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Our nonvested stock granted prior to 2012 and restricted stock units granted to our Board of Directors are considered participating securities since the share-based awards contain a non-forfeitable right to dividend cash payments prior to vesting. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average shares outstanding during the period.

The following table presents the calculation of basic and diluted earnings per common share from continuing operations:
