Explanation of Responses:

Id	Content
F1	The original Form 4, filed on January 3, 2024, is being amended by this Form 4 amendment to correct an administrative error of the issuer, whereupon the number of shares withheld to satisfy tax withholding obligations upon vesting of certain restricted performance shares was misreported as 13,870 shares. The corrected transaction reflects an increase of 325 shares withheld by the issuer as a result such vesting and a corresponding reduction in the number of shares beneficially owned by the reporting person.
