Mar. 31, 2017

Basic earnings per share is computed based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed based on the weighted average number of common shares plus the effect of dilutive potential common shares outstanding during the period. A reconciliation of the numerators and denominators of the basic and diluted per share computations of common stock based on the Company's consolidated earnings is as follows (in thousands, except per share amounts):

Potential common shares outstanding that are considered antidilutive are excluded from the computation of diluted earnings per share. Potential common shares related to stock options and other awards under deferred share-based compensation programs may be determined antidilutive based on the application of the treasury stock method. Potential common shares are also considered antidilutive in the event of net loss from operations. The number of potential shares outstanding that were considered antidilutive using the treasury stock method and were excluded from the computation of diluted earnings per share, weighted for the portion of the period they were outstanding are as follows (in thousands):
