Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation and Other Long Term Incentive Compensation	Stock-Based and Other Long Term Incentive Compensation During the second quarter of 2017, our stockholders approved an amendment to the 2015 Employee Equity Incentive Plan (“2015 Plan”) to increase the number of shares authorized for issuance under the 2015 Plan from 7,800,000 to 9,800,000 shares. At June 30, 2017, 1,856,515 shares remained available for award under the 2015 plan. During the second quarter of 2017, the Compensation Committee of our Board of Directors approved equity-based compensation to executive officers and other key employees. The awards included a grant of 747,661 shares of restricted stock units which will primarily vest in equal installments over a three-year period. Non-employee directors received shares of restricted stock totaling 98,714 shares, which will vest in full on the earlier of the day prior to the next annual meeting of stockholders following the grant date or the first anniversary of the grant date. The weighted average fair value on the date of grant for all of these awards was $7.80 per share. The Compensation Committee also approved the issuance of cash-settled awards during the second quarter of 2017, including $5.3 million of time-based cash awards and a target amount of $1.3 million of performance-based cash awards. The time-based cash awards were granted to executive officers and other key employees and primarily vest in equal installments over a three-year period. The performance-based cash awards were granted to executive officers and will be settled in cash based on the relative ranking of the Company’s total shareholder return (“TSR”) as compared to the TSR of the Company’s designated peer group for 2017. The performance period began June 1, 2017 and ends May 31, 2020, with the ending TSR price being equal to the average closing price of our shares over the 30-calendar days ending May 31, 2020 with the cash payout for each executive ranging from 0% to 150% of target. The performance-based cash awards are accrued as a liability award over the performance period based on the estimated fair value. The fair value of the performance-based cash awards is remeasured each period using a Monte-Carlo valuation model with changes in fair value recognized in the consolidated statement of operations.
