        <footnote id="F4">Due to an administrative error, the reporting person's Form 4 filed on March 17, 2022 inadvertently under-reported the number of restricted stock units acquired as a result of the achievement of the performance criteria of the performance-based restricted stock units granted on August 14, 2020 by 1 share. As a result, such share was inadvertently excluded in the total amounts reported in Column 5 on the reporting person's Form 4s filed on March 17, 2022, March 22, 2022, March 24, 2022, April 27, 2022, April 29, 2022 and January 26, 2023.
