⁽⁴⁾ The Company’s Total Shareholder Return (“TSR”) and the Company’s Peer Group TSR reflected in these columns for each applicable fiscal year is calculated based on a fixed investment of $100 at the applicable measurement point on the same cumulative basis as is used in Item 201(e) of Regulation S-K. The Peer Group used to determine the Company’s Peer Group TSR for each applicable fiscal year is our peer group as disclosed in this proxy statement.

⁽⁵⁾ Amounts reflect the Company’s net income as reported in our audited financial statements for the applicable year.

⁽⁶⁾ While we use numerous financial and non-financial performance measures to evaluate performance under our compensation programs, Modified Free Cash Flow per share is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used to link the compensation actually paid to NEOs to company performance. This performance measure may not have been the most important financial performance measure for 2021 and 2020 and the Company may determine that a different financial performance measure is the most important financial performance measure in future years.

Discussion and Analysis

In accordance with Item 402(v) requirements, we are providing the following charts to describe the relationships between information presented in the Pay versus Performance Table.

1. Relationship Between Compensation Actually Paid for CEO and NEOs (Average) vs. Cumulative TSR of Company and the Peer Group

The following graph illustrates the trend in “compensation actually paid” over the three years compared to our TSR performance, as well TSR relative to our peer group. This illustrates that compensation moved in alignment with our TSR performance in 2021 and 2022. Our change in TSR performance was greater than our peer groups change in TSR performance from 2021 to 2022.

2. Relationship Between Compensation Actually Paid for CEO and NEOs (Average) vs. Net Income (Loss)

The graph below illustrates the trend in “compensation actually paid” over the three years to our GAAP Net Income (Loss). This illustrates that in 2021 compensation moved in alignment with net income, increasing in 2021. For 2022, compensation increased, and net income increased.

3. Relationship Between Compensation Actually Paid for CEO and NEOs (Average) vs. Non-GAAP Modified Free Cash Flow per Share

The graph below illustrates the trend in “compensation actually paid” over the three years to our Modified Free Cash Flow per share (non-GAAP). The definition of Modified Free Cash Flow set forth above in this proxy statement is divided by the number of Company common shares during the applicable period to determine Modified Free Cash Flow per share. This illustrates that in 2021 compensation increased and Modified Free Cash Flow per Share increased. For 2022, compensation moved in alignment with Modified Free Cash Flow per share, increasing significantly in 2022.
