15. NET INCOME (LOSS) PER COMMON SHARE:

Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding for the period excluding unvested restricted stock awards, restricted stock units and performance units. Diluted net income (loss) per common share reflects the potential dilution from the exercise or conversion of securities into common stock, the effect of unvested restricted stock awards, restricted stock units and performance units, and the impact of shares to be issued under the ESPP.

The following table is a reconciliation of net income (loss) and the shares used in calculating basic and diluted net income (loss) per common share for the three months ended March 31,2014 and 2013 (in thousands, except share and per share data):

Diluted	$	0.09	$	(0.10	)

For the three months ended March 31,2014 the effects of certain performance unit awards of 53,890 were excluded from the calculation of diluted EPS as their impact would have been antidilutive as the units would not be issued if the end of the reporting period was the end of the performance period. For the three months ended March 31,2013, the combined effects of outstanding stock options, unvested restricted stock awards, restricted stock units and performance units of 1,404,031, and the impact of shares to be issued under the ESPP, which was minor, were excluded from the calculation of diluted EPS as their impact would have been antidilutive.
