Size vs CEO pay

This purchase equals about 6.6% of the CEO's reported total pay for fiscal 2025 ($36.4M)

Purchase value ÷ the CEO's total from the Summary Compensation Table, as tagged in the pay versus performance table of the company's proxy statement (DEF 14A), filed 2026-04-30. The proxy names Andrew C. Florance as CEO for that year. A size comparison, not a judgement
