STOCK-BASED COMPENSATION

We account for stock-based compensation under the fair value recognition provisions of ASC Topic 718 - Compensation - Stock Compensation.

Stock-based compensation cost for restricted stock grants is measured based on the closing fair market value of our common stock on the date of grant. We recognize stock-based compensation cost over the award’s requisite service period on a straight-line basis for time-based restricted stock grants.

We granted 130,442 shares of restricted common stock awards during the twelve-month period ended December 31, 2015, which had a weighted-average grant date fair value of $20.38 per share. We granted 103,156 shares of restricted stock during the twelve-month period ended December 31, 2014, which had a weighted-average grant date fair value of $13.86 per share.

The following table presents certain information related to the activity of our non-vested common stock grants:
