Stock Incentive Plan

14 Stock Incentive Plan

Commencing with grants in February 2016, employees receive 50% of their long-term incentive (LTI) grant value in the form of performance shares (PSs) and 50% in the form of restricted stock units (RSUs).

The grantee may earn 0%-200% of the target number of PSs based on the Company’s achievement of specified targets. The performance targets are for: 1) the Company’s compound annual growth rate (CAGR) for sales and 2) the Company’s CAGR in earnings per share relative to an established benchmark growth rate. Each performance target is weighted 50% and results are measured at the end of the three-year performance period. Each PS represents a promise to transfer a share of the Company’s common stock to the employee following completion of the performance period, provided that the performance goals mentioned above are met and provided, further, that the grantee remains employed through the performance period, subject to certain limited exceptions. The RSUs granted on February 15, 2016 and May 9, 2016 vest in three approximately equal annual installments beginning on the first anniversary of the grant date, and the RSUs granted on February 19, 2017 will vest in one installment on the third anniversary of the grant date, in each case subject to the grantee’s continued employment with the Company on each vesting date, subject to acceleration of vesting in certain circumstances. The RSUs and PSs granted in 2017 entitle the grantee to receive dividend equivalents in the form of additional RSUs and PSs subject to the same vesting conditions as the underlying RSUs and PSs, respectively.

The fair value of the RSUs and PSs granted under the LTI program are calculated as the grant date fair value of the shares expected to be issued. For the grants made during 2017, the fair value of a PS and a RSU is calculated by using the closing stock price at grant date. For the grants made during 2016 and earlier, the fair value of a RSU and a PS was estimated using the Black Scholes valuation model. The grant date fair value for the RSUs at February 19, 2017 was $7.9 million. This cost will be amortized straight line over the vesting period. The grant date fair value of the PSs at February 19, 2017 was also $7.9 million. For PSs, the grant date fair value of the number of awards expected to vest is based on the Company’s best estimate of ultimate performance against the respective targets and is recognized as compensation cost on a straight-line basis over the requisite vesting period of the awards. The Company assesses the expected achievement levels at the end of each quarter. As of September 30, 2017, the Company believes it is probable that the performance conditions for the two grants will be met, although at a different level, and has accrued for the compensation expense accordingly. The cumulative effect of the change in estimate is recognized in the period of change as an adjustment to compensation expense.

The Company’s non-employee directors historically received grants of fully-vested shares of the Company’s common stock as payment of 50% of their annual base retainer, which shares were granted in arrears following a year of service.  The Company’s non-employee directors received their last grant of fully-vested shares of the Company’s common stock pursuant to the prior program on the date of the 2017 annual general meeting of stockholders (AGM). The grant date fair value for the fully-vested shares of the Company’s common stock granted to the Company’s non-employee directors at May 9, 2017 was $1.2 million. Pursuant to the Company’s new director compensation policy, commencing May 2017, the Company’s non-employee directors receive RSUs as payment of 50% of their annual base retainer, which RSUs vest in one installment on the earlier of the date of the next AGM or the first anniversary of the grant date, in each case subject to the grantee’s continued service as a non-employee director on the vesting date. The RSUs granted to the Company’s non-employee directors entitle the grantee to receive dividend equivalents in the form of additional RSUs subject to the same vesting conditions as the underlying RSUs. The grant date fair value for the RSUs granted to the Company’s non-employee directors at May 9, 2017 was $1.0 million.
