(7)    STOCK-BASED COMPENSATION

As of March 31, 2015, we have unvested restricted stock awards granted under stock-based employee compensation plans that are described more fully in Note 12 to the consolidated financial statements in our 2014 Form 10-K. We did not grant any stock options during 2015 or 2014.

We record compensation expense for restricted stock awards (unvested shares) based on the quoted market price of our stock at the grant date and amortize the expense over the vesting period. Restricted stock awards generally vest over four years. As of March 31, 2015, total compensation expense to be recognized in future periods was $296. The weighted average period over which this expense is expected to be recognized is 2.5 years. The following table shows the allocation of the compensation expense we recorded during the three months ended March 31, 2015 and 2014, respectively, related to unvested shares:

	Three Months Ended March 31,
	2015		2014
Cost of revenues	$	3	$	3
Selling expense		1		3
Engineering and product development expense		2		6
General and administrative expense		24		29
	$	30	$	41

There was no compensation expense capitalized in the three months ended March 31, 2015 or 2014.
