Earnings Per Share [Abstract] |
Loss Per Common Share | 15. Loss Per Common Share The Company applies the two-class method in calculating per share data. Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares used in basic loss per share during the period. Diluted loss per share is determined on the assumption that outstanding dilutive stock options have been exercised and the aggregate proceeds as defined were used to reacquire common stock using the average price of such common stock for the period. The following table summarizes the calculation of net loss and weighted average common shares and common equivalent shares outstanding for purposes of the computation of loss per share (in thousands, except share and per share amounts):

Diluted |  | $ | (4.32 | ) |  | $ | (3.52 | ) |  | $ | (2.51 | )
For the calculation of diluted loss per share for fiscal years 2017 and 2016, 201,800 and 159,000 stock options, respectively, were excluded in the calculation of weighted average shares outstanding as a result of their impact being antidilutive. No stock options were excluded in the calculation of weighted average shares outstanding for fiscal year 2015.
