Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	9. Stock-Based Compensation During the three months ended December 31, 2016, the Company issued 102,500 shares of restricted stock under its 2014 Long Term Incentive Plan, as amended (the “Plan”). The weighted average grant date fair value of the restricted stock was $21.22 per share. The grant date fair value of these awards was $2.2 million, which will be charged to expense over the next four years as the restrictions lapse. Compensation expense for restricted stock awards was determined based on the closing market price of the Company’s stock on the date of grant applied to the total number of shares that are anticipated to fully vest. Recipients of restricted stock awards are entitled to vote such shares and are entitled to dividends, if paid. During the three months ended December 31, 2016, the Company also issued 51,300 nonqualified stock options under the Plan. The options issued are based upon three tiers, each with separate service based vesting conditions and market conditions that affect exercisability. Market based conditions are based on achieving a specified market return on the Company’s stock price. Compensation expense for the nonqualified stock option awards was determined based on a Monte Carlo simulation, which incorporates the possibility that the market conditions may not be satisfied. The weighted average grant date fair value of the options issued was determined to be $9.35 per option resulting in unrecognized compensation costs of $0.5 million, which will be charged to expense over the requisite service period of the options, ranging from 18 to 36 months. As of December 31, 2016, the Company had unrecognized compensation expense of $7.7 million relating to restricted stock awards. This unrecognized compensation expense is expected to be recognized over a weighted average period of 3.0 years. In addition, the Company had $0.6 million of unrecognized compensation expense related to nonqualified stock option awards which is expected to be recognized over a weighted average period of 1.8 years. As of December 31, 2016, a total of 289,300 shares of restricted stock and 206,300 nonqualified stock options shares were outstanding.
