[1] As a result of the net loss for the three and six months ended June 30, 2013, diluted earnings per share was calculated using the basic weighted average shares outstanding as the effect of potential common shares would have been anti-dilutive. Had there been net earnings, the impact of dilutive stock options would have been calculated as 41,360 and 52,873 respectively for the three and six months ended June 30, 2013.
[2] For the three and six months ended July 1, 2012, as a result of net earnings, dilutive options were determined using the treasury stock method, using an average share price of $3.48 and $3.32 per share, respectively. For the three and six months ended July 1, 2012, the calculation did not include 43,600 and 317,100 stock options, respectively, as the effect would have been anti-dilutive.
