Earnings Per Share [Abstract]  
Income Per Share
Income Per Share
Income per share has been computed using the two-class method. Income per common share under the two-class method is computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders 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. Classification of the Company's unvested restricted stock, which contain rights to receive nonforfeitable dividends, are deemed participating securities under the two-class method. Under the two-class method, earnings attributable to unvested restricted shares are deducted from income from continuing operations in the computation of net income attributable to common stockholders. The table below is a reconciliation of the numerator and denominator used in the computation of basic and diluted income per share (dollars in thousands):

(1)  Assumes the most dilutive issuance of potentially issuable shares between the two-class and treasury stock method unless the result would be anti-dilutive.

The Corporation intends to satisfy its exchange obligation for the principal amount of the Convertible Notes to the note holders entirely in cash, therefore, the "if-converted" method does not apply and the treasury stock method is being used. As the Corporation's stock price is below the conversion price, there are no potentially dilutive shares associated with the Convertible Notes.
