Explanation of Responses:

Id	Content
F1	The reported number is based on a 401(k) plan statement dated as of October 18, 2021.
F2	Each performance stock unit represents a contingent right to receive between 0% and 300% of one share of Issuer common stock. The reported number of securities represents the target number of shares that may be earned. The actual number of shares that may be earned will be calculated by comparing the Issuer's relative total shareholder return to the total shareholder return for each company comprising the Issuer's peer group over a three-year performance period.
F3	The actual number of shares that may be earned will be determined by the Compensation Committee based on the Issuer's actual performance. Earned and vested performance stock units will generally be settled on the later of October 15, 2024 or the Compensation Committee's determination of performance.
F4	Each restricted stock unit represents a contingent right to receive one share of Issuer common stock. Vesting of the restricted stock units is contingent on satisfaction of a performance hurdle tied to the Issuer's fiscal year 2022 financial performance.
F5	Restricted stock units vest in three equal annual installments, beginning on the first anniversary of the grant date and ending on October 15, 2024.
