For a discussion of how the Company views its executive compensation structure, including alignment with Company performance, see the Compensation Discussion and Analysis (beginning on page 35 The use of the term “compensation actually paid” (“CAP”) is required by the SEC’s rules. Neither CAP nor the total amount reported in the Summary Compensation Table (“SCT”) reflect the amount of compensation actually paid, earned or received during the applicable year. Per SEC rules, CAP was calculated by adjusting the SCT total values for the applicable year as described in the footnotes to the following table.

| Compensation Actually Paid vs. Total Shareholder Return | | | Pay Versus Performance Comparative Disclosure As described in more detail in the CD&A, a substantial portion of the Company’s executive compensation program is variable and at risk based on operational, financial, strategic and share price performance. While the Company utilizes several performance measures to align executive compensation with Company performance, not all of those Company measures are presented in the table above. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between the information presented in the table above. CAP and Company TSR CAP over the last four years is closely aligned with the Company’s TSR performance as presented in the chart below. This is because a significant portion of CAP is comprised of equity awards. As described in more detail in the section titled “2023 Target Compensation Benchmarks,” approximately 65% of the CEO’s 2023 target compensation and, on average, 61% of the non-CEO NEOs’ 2023 target compensation is comprised of equity awards delivered in MSUs and PSUs, tied to absolute and relative stock price performance in addition to financial performance. The Company’s TSR over the 4-year period ending December 31, 2023 was -9.2%, while the Company’s peer group TSR was 42% for the same period of time.
