(1)PSU awards, similar to DPU awards that were replaced by PSUs in fiscal year 2021, contain performance conditions for which accrual of expense is based on the probable outcome of the performance conditions. Vesting of DPUs related to the measurement years of both fiscal year 2020 and 2019 was deemed not probable at the end of each fiscal year. DPUs were then discontinued by the Company prior fiscal year 2021. PSUs pertaining to the measurement year of fiscal year 2021 vested at 100% since the performance conditions were fully achieved.
