(1) Mr. Colombo retired as CEO effective October 31, 2021. Mr. Myers was appointed CEO effective November 1, 2021.  Therefore, we provide both incumbent comparisons in 2021.

(2) Amounts represent compensation actually paid to our CEO and the average compensation actually paid to our remaining NEOs for the relevant fiscal year, as determined under SEC rules.  Compensation actually paid to our NEOs represents the “Total” compensation reported in the Summary Compensation Table for the applicable fiscal year, as adjusted as follows.  Reconciliation of adjustments made to SCT to arrive at CAP for the CEO and average NEO:
