PAY VERSUS PERFORMANCE

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are providing the information below to illustrate the relationship between the SEC-defined compensation actually paid (“CAP”) and various measures used to gauge the Company’s financial performance in conformance with Item 402(v) of Regulation S-K. CAP is calculated in accordance with Item 402(v) of Regulation S-K and differs from compensation shown in the Summary Compensation Table on page 41 for the CEO and other NEOs. See below for a reconciliation of the total compensation shown in the Summary Compensation Table to CAP. The Compensation Committee does not utilize CAP as the basis for making compensation decisions. For further information concerning our compensation philosophy and how we align executive compensation with our performance, see the Compensation Discussion and Analysis section beginning on page 26.

The following table sets forth information concerning the compensation of our NEOs for each of the fiscal years ended December 31, 2020, 2021 and 2022, and our financial performance for each such fiscal year:

Compensation Actually Paid vs. Total Shareholder Return [Text Block]

CAP versus Company TSR and Peer Group TSR

TSR amounts reported in the graph assume an initial fixed investment of $100 and that all dividends, if any, were reinvested.

As shown in the chart above, the PEO and other NEOs CAP amounts are directionally aligned with the Company’s TSR. We believe the use of equity awards in the Long-Term Incentive Plan, strengthens the alignment between our executives’ compensation plans and shareholders’ interests. The TSR peer group is based on the S&P Composite 1500 Health Care Technology Index, which reflects the Company’s industry sector. The Company’s three-year cumulative TSR was below that of the S&P Composite 1500 Health Care Technology Index.

Compensation Actually Paid vs. Net Income [Text Block]

CAP versus Net Income

As shown in the chart above, the Company’s net income has increased over the three-year measurement period. The changes in CAP for the PEO and other NEOs are not proportionally correlated with changes in net income over the same measurement period. This is due in part to PEO and other NEO compensation being largely equity-based compensation, as well as the impacts of the impairments and change in valuation allowance on net income in accordance with GAAP. In addition, while net income is one of several factors used to assess Company performance, the Company generally does not use net income as a metric to determine compensation levels or incentive plan payout.

Compensation Actually Paid vs. Company Selected Measure [Text Block]

CAP versus Free Cash Flow

As shown in the chart above, the PEO and other NEOs’ CAP amounts are not directionally aligned with the company selected measure of Free Cash Flow. As discussed in the Long-Term Incentive Plan for 2022 on page 36, Free Cash Flow is a key performance metric for 2022. However, performance-based equity awarded under the Long-Term Incentive Plan is generally based on a three-year performance period and the value upon vesting is reflective of the prior three-year performance period. Additionally, while we believe Free Cash Flow is the most important financial performance measure used by us to link compensation actually paid to our NEOs for the most recently completed fiscal year, this metric was not used by us to link NEO compensation to Company performance in either of the fiscal years ended December 31, 2021 or 2020.
