Explanation of Responses:

Id	Content
F1	Restricted stock units convert into common stock on a one-for-one basis.
F2	In connection with the vesting on February 17, 2026, of 799 restricted stock units ("RSUs") previously granted to the reporting person, all 799 shares of common stock was deferred, resulting in the reporting person's receipt of 799 deferred stock units ("DSUs") pursuant to the issuer's Long Term Equity Deferred Compensation Plan. The reporting person is therefore reporting the disposition of 799 shares of common stock in exchange for an equal number of DSUs.
F3	Granted on February 17, 2023, vesting ratably over three years with the first vest date of February 17, 2024.
F4	Each DSU represents a right to receive, at settlement, one share of common stock of the issuer.
F5	The DSUs become payable in annual installments over five years while in active service, beginning as soon as feasible after June 1, 2028.
