Award vesting terms		The Long-Term Incentive Performance Restricted Units have a three-year performance period beginning on January 1, 2019 and ending on December 31, 2021 and vest based upon the Company’s achievement of specified performance goals for Fiscal 2021, as defined by the 2019 Long-Term Incentive Grant. The total number of Long-Term Incentive Performance Restricted Units eligible to vest will be based on the level of achievement of the performance goals and ranges from 0% (if below threshold performance) up to 100% (for target or above performance). Upon achievement of the performance goals, only 50% of the award for a given level of performance will vest, with the remaining 50% subject to a one-year performance test period. The goal achieved must be met again or exceeded the next fiscal year before the remaining units are earned.
