Earnings per share [Abstract]

Earnings per share

3.  Earnings per share

Basic net income per share was computed on the weighted average number of shares outstanding.  Diluted net income per share was computed under the treasury stock method, assuming the conversion as of the beginning of the period, for all dilutive stock options.  Of 676 thousand and 725 thousand shares and options outstanding at March 31, 2014 and 2013, respectively, 96 thousand and 341thousand were anti-dilutive, respectively.  These shares and options have been excluded from the computations of diluted earnings per share for their respective period.  There were no adjustments to net income for either period.
