Earnings Per Share [Abstract] |
Earnings Per Share | 2. Earnings Per Share Basic earnings per share represents income available to common stockholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate solely to outstanding stock options and are determined using the treasury stock method. The following table sets forth the weighted average shares outstanding used in the computations of basic and diluted earnings per share. All share and per share data has been adjusted to reflect the retroactive effect of the 10% stock dividend declared during the period ending March 31, 2013. (in thousands)
