Share-based Compensation [Abstract] |
Stock-based compensation plan | PLANS 2016 Equity Awards On September 22, 2015, the Board of Directors approved the adoption of the Executive Long-Term Incentive Compensation Plan, pursuant to which certain named executive officers ("NEOs") and other key executives may earn variable equity payouts based upon us achieving certain key performance metrics. On February 23, 2016, NEOs received 24,677 restricted stock units ("RSU") vesting equally over 3 service periods ending December 31, 2016, December 31, 2017 and December 31, 2018, and 29,633 performance share units ("PSU") with vesting contingent on financial performance measures at the end of a 34-month performance period ending December 31, 2018. The performance criteria for the PSUs consists of the following financial measures during the performance period: (i) cumulative Adjusted EBITDA; (ii) cumulative free cash flow; and (iii) our relative total shareholder return ("TSR"). Our TSR will be ranked versus the companies in the Russell 2000 index and will be calculated based on our relative placement against the Russell 2000 index. Measurement against these criteria will be determined against a payout curve which provides a maximum number of performance share units of 250% of the original award. The total compensation cost we will recognize under the PSUs will be based upon the results of the two financial measures. We also awarded 67,468 of restricted stock shares to other employees, the majority of which vest equally over 3 service periods ending in the first quarter of 2019. In 2016, we recognized compensation expense of $1.2 million for 2016 awards and $2.9 million for awards granted prior to 2016. At March 31, 2016, unrecognized compensation expense attributable to unvested 2016 RSU and PSU awards was $7.1 million and attributable to 2016 other awards was $8.3 million. Executive Retirement Our former Executive Chairman of the Board of Directors and Chief Executive Officer, Robert L. Evans, retired effective September 30, 2015. In conjunction with Mr. Evans' retirement, 65,000 shares of restricted stock vested on March 31, 2016. Mr. Evans was awarded these shares under a 2006 restricted stock agreement which specified that the stock vested six months after his retirement. Compensation expense for these shares was fully recognized prior to 2016.
