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 six months ended June 30, 2019 and 2018, respectively, was as follows: 

	Three Months Ended				Six Months Ended
	Jun. 30,2019		Jun. 30,2018		Jun. 30,2019		Jun. 30,2018

Total share-based compensation	$	364	$	473	$	651	$	650

Equity awards granted during the three and six months ended June 30, 2019 and 2018 were as follows:
