Share-based Compensation [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, 2018 and 2017, respectively, was as follows:

	Three Months Ended		Six Months Ended
	Jun. 30, 2018	Jun. 30, 2017	Jun. 30, 2018	Jun. 30, 2017

Cost of goods sold	$11	$8	$15	$10
Research and development	107	63	149	88
