Share Based Compensation Arrangement By Share Based Payment Award [Line Items]
Incentive plan terms						for fiscal 2016 and fiscal 2017 the Compensation Committee established performance targets which cover a two-year performance period (each a “Performance Period”), thereby creating overlapping Performance Periods. Each participant in the plan is 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 is based on one year of annual salary.
