Compensation Actually Paid vs. Total Shareholder Return
Compensation Actually Paid (CAP) versus TSR: As shown in the first table of this Pay versus Performance section, the PEO’s and Non-PEO NEOs’ CAP values are higher than the corresponding grant date fair values in the SCT, which is consistent with the Company’s positive TSR each year, as shown in the graphs immediately above and below. This is due primarily to the Company’s use of equity incentives, the value of which is tied directly to stock price in addition to the Company’s financial performance. Our executive compensation program emphasizes equity-based pay, with the majority of target direct compensation for both the PEO and Non-PEO NEOs delivered via equity-based awards.
CAP v TSR.jpg
        
Compensation Actually Paid vs. Net Income
CAP versus Net Income: The Compensation and Talent Committee does not use Net Income to determine compensation opportunity or outcomes.
The committee believes that Adjusted EPS is a superior indicator of core operating performance and profitability. In addition, it is common for our shareholders to use Adjusted EPS and other metrics to inform their views of historical and future expectations for underlying operational performance. Net Income, on the other hand, can show variability year over year due to timing of specific events or because of unusual or non-recurring events.
Therefore, we would not necessarily expect to see alignment between Net Income and CAP. The Compensation and Talent Committee is focused on alignment of our compensation programs to metrics that most appropriately measure our profitability and sustainable long-term growth. 		       
Compensation Actually Paid vs. Company Selected Measure
CAP versus Adjusted EPS: The chart below compares the PEO’s and Non-PEO NEOs’ CAP values to our Company-Selected Measure (CSM), Adjusted EPS. As noted above, for each fiscal year presented, CAP values are higher than the corresponding grant date fair value of stock awards shown in the SCT, which is consistent with our growing Adjusted EPS.
The Company focuses on Adjusted EPS in our incentive plans because earnings per share is one of the principal measures used by shareholders to assess financial performance results and establish a price for the Company’s equity, and it is a central component of our guidance to shareholders. The use of Adjusted EPS in our incentive plans aligns our executives’ interests with the broader set of strategic objectives they are tasked to manage, keeping enterprise value and shareholder interests at the forefront of management decisions on both a short- and long-term basis. Accordingly, Adjusted EPS is included as a key metric in both our annual and long-term incentives.
Given this emphasis on Adjusted EPS, its impact on the value of the Company’s shares and therefore CAP values — both positive and negative — is significant. Adjusted EPS drives a significant portion of the Company’s annual cash incentive and determines a significant portion of PSU award payouts to be earned during any three-year PSU performance period.

Total Shareholder Return Vs Peer Group
Total Shareholder Return (TSR): Company versus Peer Group: The Company’s five-year cumulative TSR has significantly exceeded that of the S&P 500 Health Care Index. We selected the S&P 500 Health Care Index as the comparator because it is generally available to shareholders and broadly used by other companies in the same industry.
