In accordance with the requirements of Item 402(v) of Regulation S-K, the fair values of unvested and outstanding equity awards held by our NEOs were remeasured as of the end of each fiscal year, and as of each vesting date, during the years displayed in the table above. For options, the fair values as of each measurement date were determined using a binomial lattice model, with assumptions and
methodologies regarding volatility, dividend yield and risk-free rates that are generally consistent with those used to estimate fair value at grant under generally accepted accounting principles. For relative TSR PSUs, the fair values as of each measurement date (prior to the end of the performance period) were determined using a Monte Carlo simulation pricing model. For Adjusted Free Cash Flow and ROIC PSUs, the fair values reflect the probable outcome of the performance vesting conditions as of each measurement date.
(3)
Amounts reflect the average of the total compensation reported for LivaNova’s NEOs (excluding Mr. McDonald, who was our CEO in all of the years presented) in the “Total” column of the Summary Compensation Table for each corresponding year. The NEOs whose compensation was included for purposes of calculating the average amounts in each applicable year in this column are as follows: (i) for 2022, Messrs. Shvartsburg and Dolci and Mses. Skeffington and Hebbelinck; (ii) for 2021, Messrs. Shvartsburg and Dolci and Mses. Skeffington and Hebbelinck; and (iii) for 2020, Messrs. Huston, Shvartsburg Dolci and Khoury, and Ms. Skeffington.

Compensation Actually Paid vs. Total Shareholder Return [Text Block]
Relationship Between Compensation Actually Paid (CAP) for CEO and Non-CEO NEOs (Average) vs. Cumulative TSR of Company and the Peer Group
The following chart shows the relationship between Compensation Actually Paid to our CEO and the average Compensation Actually Paid to our non-CEO NEOs relative to the Company’s TSR as well as the TSR of our performance graph peer group. As the chart demonstrates, historically, Compensation Actually Paid has been directionally aligned with the movement of our TSR, predominantly as a result of the fact that a substantial portion of executive officer compensation is in the form of long-term incentives where value is tied directly to The Company’s share price. Our TSR has also been directionally aligned with the TSR of our performance graph peer group.

Compensation Actually Paid vs. Net Income [Text Block]
Relationship Between Compensation Actually Paid for CEO and Non-CEO NEOs (Average) vs. Net Income
The following chart shows the relationship between net income and Compensation Actually Paid to our CEO and the average Compensation Actually Paid to our non-CEO NEOs. Net income does not play a direct role in determining compensation for our short- and long-term incentive plans. To the extent that net income drives stock price performance and returns value to our shareholders, we would expect net income to impact compensation through the equity instruments included in our long-term incentive plan.

Compensation Actually Paid vs. Company Selected Measure [Text Block]
Relationship Between Compensation Actually Paid for CEO and Non-CEO NEOs (Average) vs. Adjusted Net Income
The following chart shows the relationship between adjusted net income and Compensation Actually Paid to our CEO and the average Compensation Actually Paid to our non-CEO NEOs. Adjusted net income is one of the two financial metrics of our short-term incentive plan and is one of the factors that the Compensation Committee considers when reviewing the compensation of our NEOs annually. Although there was meaningful correlation between CAP and adjusted net income for 2020 and 2021, Compensation Actually Paid in 2022 decreased significantly relative to 2021 despite a significant improvement in adjusted net income in 2022. In a volatile stock market, the CAP for our NEOs is strongly impacted by LivaNova Stock price, which aligns with shareholders’ interests, although the stock price at the end of 2022 did not necessarily reflect the Company’s improved adjusted net income performance.
