Earnings per share [Abstract]

Earnings per share

4.  Earnings per share

Basic net income (loss) per share was computed on the weighted average number of shares outstanding.  Diluted net income (loss) 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 764 thousand and 668 thousand shares and options outstanding at September 30, 2013 and 2012, respectively, 293 thousand and 346 thousand were anti-dilutive, respectively.  These 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.
