During the three months ended June 30, 2016 and 2015, the Company granted 161,000 and 364,695 restricted stock awards, respectively. These awards generally vest over 3 years. Awards for restricted stock include both time-based and performance-based awards. For options and awards that vest upon the passage of time, expense is being recorded over the vesting period. Performance-based awards are expensed over the requisite service period based on probability of achievement. The estimated fair value of the Company’s stock-based awards, less expected annual forfeitures, is amortized over the awards’ service period. The total unrecognized compensation cost for unvested outstanding stock options was $0.5 million at June 30, 2016. This expense will be recognized over a weighted average expense period of approximately 2.2 years. The total unrecognized compensation cost for unvested outstanding restricted stock was $3.3 million at June 30, 2016. This expense will be recognized over a weighted-average expense period of approximately 2.0 years. The Company did not grant any stock options during the three months ended June 30, 2016 or 2015.
