Jun. 30, 2019

Basic earnings (loss) per share represents net income (loss) for the period divided by the weighted average number of shares of common stock outstanding for the period.

The following are the number of shares of common stock used to compute the basic and diluted earnings (loss) per share for each period:



	Three Months Ended June 30,		Six Months Ended June 30,
	2019	2018	2019	2018
Weighted average shares used in basic computations	42,987,915	42,893,498	42,960,124	42,886,867
Dilutive effect of stock options and restricted stock units	257,438	16,519	104,372	16,921
Weighted average shares used in diluted computations	43,245,353	42,910,017	43,064,496	42,903,788

For the three and six months ended June 30, 2019, there were 38,806 and 85,918 shares, respectively, not included in the computation of diluted weighted average shares because their effect would have been antidilutive. For the three and six months ended June 30, 2018, there were 66,000 and 177,000 shares, respectively, not included in the computation of diluted weighted average shares because their effect would have been antidilutive.
