Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

Each performance-based restricted stock units ("PSU") was issued under the Plan and represents a contingent right to receive one share of common stock or its cash equivalent, as determined at the time of settlement by the Committee pursuant to the terms of the Plan. The number of PSUs that vest can range from 0% to 200% of the target number of PSUs subject to the award, plus an additional incentive based on the Company's market capitalization at vesting, as more fully set forth in the applicable award agreement. The number of shares in this row represents the actual level of performance (200%) plus the additional incentive shares described above. The reporting person's PSUs were granted on July 10, 2023 and they vested on May 17, 2026, the third anniversary of the vesting commencement date, with 60% of the after-tax value of such PSUs settled in cash.

Footnote F2

In an exempt disposition to the Company under Rule 16b-3(e), the reporting person remitted shares to the Company in connection with the satisfaction of tax withholding obligations arising out of the vesting of the PSUs.
