Incentive plan terms								for fiscal 2016 and fiscal 2017 the Compensation Committee established performance targets which covered a two-year performance period (each a “Performance Period”), thereby creating overlapping Performance Periods. Each participant in the plan was entitled to receive an award based on that participant’s “Target Cash Value” which is defined as the participant’s annual base salary (on the participant’s effective date) multiplied by his or her LTIP percentage, which was 100% for the Company’s Chief Executive Officer, 70% for senior executives and 25% for other participants in the plan. Effective October 22, 2018, the LTIP percentage for its vice president managing director level was increased from 25% to 50%. Because of the overlapping two-year Performance Periods, the Target Cash Value for any award was based on one year of annual salary.

All awards granted under both the 2016-2017 LTIP and 2017-2018 LTIP were in restricted stock units (RSUs).
