Pay Versus Performance Table

Pursuant to the PvP Rules, the Pay versus Performance Table (set forth below) is required to include for each year the CAP to the CEO and the average CAP for non-CEO named executive officers. CAP represents a new calculation of compensation that differs significantly from the Summary Compensation Table calculation of compensation, as well as from the way in which the Organization and Compensation Committee views annual compensation decisions, as discussed in the Compensation Discussion and Analysis. For example, the CAP calculation for a given year includes the change in fair value of multiple years of equity grants that are outstanding and unvested during the year, whereas the Summary Compensation Table calculation includes only the grant date fair value of equity awards that are granted during the year. These differences result in a CAP calculation that may be higher or lower than the corresponding Summary Compensation Table calculation, and that also may be more significantly impacted by changes in stock price. It is also important to note that outstanding equity awards may be represented in more than one year of the Pay versus Performance Table.

Equity grants (performance-based restricted stock units, restricted stock units and stock options) constitute a meaningful portion of compensation for the CEO and other NEOs. The value of equity grants will not be realized before applicable restriction periods and/or conditions lapse (including, with respect to the performance-based restricted stock units, the achievement of pre-determined performance goals) and the ultimate value of such awards is subject to changes in stock price. While each participant was awarded a target number of performance-based restricted stock units, the actual number of performance-based restricted stock units earned could vary from zero (0) up to two (2) times target, if performance objectives are meaningfully exceeded, and no participant will receive any portion of performance-based restricted stock units if the threshold performance objectives are not met.

(1) The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Broussard (our Director, President, and Chief Executive Officer) for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to “Summary Compensation Table” in the proxy statement.

(2) The dollar amounts reported in column (c) represent the amount of CAP to Mr. Broussard, as computed in accordance with PvP Rules. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Broussard during the applicable year. In accordance with the requirements of PvP Rules, the following adjustments were made to Mr. Broussard’s total compensation for each year to determine the Mr. Broussard’s CAP:

Year	Summary     Compensation     Table Total     ($)	Equity Deductions from SCT Total(a) ($)			Equity Additions to SCT Total(b) ($)		Pension     Additions     to SCT     Total     ($)	Compensation     Actually Paid     ($)

2020	16,489,639		(11,320,367	)		23,247,961	N/A	28,417,233

(a) The amounts in this column represent the grant date fair value of equity-based awards granted during each year. Pursuant to the requirements of Item 402(c)(2)(v) and (vi) of Regulation S-K, the Summary Compensation Table is required to include only those equity awards granted during the particular year. These equity awards are generally made in the first quarter of the year.

(b) The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; (iii) for awards that are granted and vest in the same applicable year, the fair value as of the vesting date; (iv) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value; (v) for awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (vi) the dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows:

(3) The dollar amounts reported in column (d) represent the average of the amounts reported for the Company’s named executive officers (NEOs) as a group (excluding Mr. Broussard, who has served as our CEO since 2013) in the “Total” column of the Summary Compensation Table in each applicable year. The names of each of the NEOs (excluding Mr. Broussard) included for purposes of calculating the average amounts in each applicable year are (a) for 2022, Susan Diamond, T. Alan Wheatley, Timothy Huval, and Joseph Ventura; (b) for 2021, Susan Diamond, Brian Kane, T. Alan Wheatley, Timothy Huval, and William Fleming; and (c) for 2020, Brian Kane, T. Alan Wheatley, Timothy Huval, and William Fleming.

(4) The dollar amounts reported in column (e) represent the average amount of CAP to the NEOs as a group (excluding Mr. Broussard), as computed in accordance with the PvP Rules. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Mr. Broussard) during the applicable year. In accordance with the requirements of the PvP Rules, the following adjustments were made to average total compensation for the NEOs as a group (excluding Mr. Broussard) for each year to determine the CAP, using the same methodology described above in Note 2:

The amounts deducted or added in calculating the total average equity award adjustments are as follows:

(5) Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.

(6) Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: Dow Jones U.S. Select Health Care Providers Total Return Index.

(7) The dollar amounts reported represent the amount of Net Income reflected in the Company’s audited financial statements for the applicable year. While the Company does not use net income as a performance measure in its executive compensation program, the measure of net income is correlated with the measure Adjusted ROIC, which the company does use when setting goals in the Company’s long-term incentive compensation program.

(8) Adjusted EPS is defined at page 61 of this proxy statement, under “Organization and Compensation Committee Report.” While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Adjusted EPS 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 by the company to link CAP to the company’s NEOs, for the most recently completed fiscal year, to company performance.
