PEO Name | Stephen B. Tanda |  |  |
Additional 402(v) Disclosure | We believe the “compensation actually paid” in each of the years reported above and over the four-year cumulative period are reflective of the Management Development and Compensation Committee’s emphasis on “pay-for-performance” as the “compensation actually paid” fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our 2023 STI and 2023 LTI awards. Because of our significant emphasis on equity awards, which represented 68% and 51% of the 2023 target pay of our CEO and the other NEOs (on average), respectively, our “compensation actually paid” is most directly impacted by our stock price performance. |  |  |
