F1	These shares were awarded as restricted performance shares in February 2020, subject to a three-year performance period that began on January 1, 2020 and ended on December 31, 2022. All requirements for 100% vesting have been met and thus the restricted shares vested on December 31, 2022 at the conclusion of the performance period.
