Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

These shares were granted as Restricted Stock Units that vest one-third on each of August 14, 2027, August 14, 2028, and August 14, 2029, subject to acceleration or forfeiture in certain specified circumstances, including the terms of the clawback policy adopted by the Board of Directors.

Footnote F2

These shares were granted as performance-based stock units ("PSUs"). Each PSU converts into the number of shares of common stock determined by applying a performance adjustment percentage to the number of units vesting on the third anniversary of the date of grant. The performance adjustment percentage is based on the cumulative adjusted EPS over the three year vesting period relative to a target cumulative adjusted EPS. The minimum performance adjustment percentage is 0% and the maximum performance adjustment percentage is 300%. These shares represent the PSUs granted, assuming a performance adjustment percentage of 100%. These PSUs are subject to acceleration or forfeiture in certain specified circumstances, including pursuant to the terms of the clawback policy adopted by the Board of Directors.
