Share-based Payment Arrangement, Noncash Expense [Abstract]

NOTE 9 - SHARE-BASED COMPENSATION

For share-based awards granted, we have recognized compensation expense based on the estimated grant date fair value method.  For these awards we have recognized compensation expense using a straight-line amortization method reduced for estimated forfeitures.  

The impact on our results of operations of recording share-based compensation, net of forfeitures, for the three and six months ended June 30, 2020 and 2019, respectively, were as follows:

	Three Months Ended				Six Months Ended
	June 30, 2020		June 30, 2019		June 30, 2020		June 30, 2019
(in thousands)
Cost of goods sold	$	15	$	10	$	21	$	16
Research and development		132		103		196		166
Selling, general and administrative		334		251		513		469
Total share-based compensation	$	481	$	364	$	730	$	651

Equity awards granted during the three and six months ended June 30, 2020 and 2019 were as follows:

	Three Months Ended				Six Months Ended

Restricted Stock Units		376,200		276,700		376,200		276,700
