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 months ended March 31, 2019 and 2018, respectively, was as follows:

	Three Months Ended

Cost of goods sold	$	5	$	4
Research and development		63		42
Selling, general and administrative		219		131
Total share-based compensation	$	287	$	177

Equity awards granted during the three months ended March 31, 2019 and 2018 were as follows:

	Three Months Ended

Restricted Stock Units		500		1,000

There were no stock option awards granted during the three months ended March 31, 2019 and 2018.

Non-employee directors Restricted Stock Units (“RSU’s”) vest over one year and options vest over three years and have a six year exercise period. Employee RSU’s typically vest over four years and employee Non-Qualified stock options typically vest quarterly over 4 years and have a six year exercise period.
