Stock-Based Compensation [Abstract] |
Stock-Based Compensation | Note 2 – Stock-Based Compensation The Company’s 2010 Omnibus Incentive Compensation Plan (the 2010 Plan) authorizes the Company, upon approval of the C ompensation C ommittee of the Board of Directors, to grant a variety of awards, including stock options, restricted shares and restricted stock units (both time-based and performance-based) and other forms of equity awards, or any combination thereof, to any director, officer, employee or consultant (including any prospective director, officer, emplo yee or consultant) of the Company. Stock options (which have not been awarded since 2015) are granted to employees with an exercise price equal to the market price of the Company’s common shares on the date of grant, generally vest over a four-year period from the date of grant and have a term of ten years. Time-based restricted stock units granted to employees generally vest over a four-year period from the date of grant, subject to the continued employment of the employee by the Company. Performance-based restricted stock unit awards generally v est over a three-year performance cycle, which includes the year of the grant, and are based upon the Company’s achievement of specified performance metrics. Awards under the 2010 Plan to non-employee directors have been in the form of restricted stock uni ts, which vest in equal quarterly installments over a one-year period, starting on the grant date. As of September 30, 2017, 3.1 million additional common shares were available for issuance under the Company’s 2010 Plan. All share-based payments to empl oyees, including grants of employee stock options, are recognized in the financial statements based on their grant date fair values. The total compensation cost recognized for stock-based awards was $2.3 million and $6.8 million for the three and nine months ended September 30, 2017, respectively, and $0.3 million and $4.3 million for the three and nine months ended September 30, 2016, respectively. The total income tax benefit recognized in the condensed income statement s fo r stock-based awards was $0.8 million and $2.5 million for the three and nine months ended September 30, 2017, respectively, and $0.1 million and $1.5 million for the three and nine months ended September 30, 2016, re spectively. Awards of restricted shares, restricted stock units, and performance-based restricted stock units are valued at the closing market price of the Company’s common shares on the date of grant. For performance-based restricted stock units, compensa tion expense is based on the probability that the performance goals will be achieved, which is monitored by management throughout the requisite service period. When it becomes probable, based on the Company’s expectation of performance during the measureme nt period, that more or less than the previous estimate of the awarded shares will vest, an adjustment to stock-based compensation expense is recognized as a change in accounting estimate. As of September 30, 2017, the unrecognized compensation cost and remaining weighted-average amortization related to stock-based awards were as follows:
|  |  |  |  |  | Performance-
|  |  |  |  |  | based
|  |  |  | Restricted |  | Restricted
|  | Stock |  | Stock |  | Stock
(in thousands) |  | Options |  | Units |  | Units(1)
Unrecognized compensation cost |  | $ 938 |  |  | $ 13,111 |  |  | $ 5,328
Remaining weighted-average |  |  |  |  |  |  |  |
amortization period | 0.9 years |  |  | 2.4 years |  |  | 1.8 years
(1) Based on the probable achievement of the performance goals identified in each award.
The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. No options were granted during the nine months ended September 30, 2017 and 2016. The total cash received by the Company as a result of stock option exercises for the nine months ended September 30, 2017 and 2016 was a pproximately $9.8 million and $5.5 million, respectively. The actual tax benefit realized as a result of stock option exercises and the vesting of other share-based awards during the nine months ended September 30, 2017 and 2016 was $4.4 million and $2.6 million, respectively. For the nine months ended September 30, 2017 and 2016, the total intrinsic value of stock options exercised was $6.5 million and $2.2 million, respectively. The Company awarde d performance-based restricted stock units to employees during the nine months ended September 30, 2017 and 2016. The number of performance-based restricted stock units that may ultimately be earned will not be determined until the end of the corresponding performance periods, and may vary from as low as zero to as high as 2.5 times the target number depending on the level of achievement of certain performance goals. The level of achievement of these goals is based upon the audited fina ncial results of the Company for the last full calendar year within the performance period. The performance goals consist of certain levels of achievement using the following financial metrics: revenue growth, operating margin expansion, and return on inve sted capital. If the performance goals are not met based on the Company’s financial results, the applicable performance-based restricted stock units will not vest and will be forfeited. Shares subject to forfeited performance-based restricted stock units w ill be available for issuance under the 2010 Plan.
