Pay vs Performance [Table Text Block]

The following table shows the total compensation for our NEOs for the past three fiscal years as set forth in the Summary Compensation Table, the “Compensation Actually Paid” (or “CAP”) to our CEO, and, on an average basis, our other NEOs, our TSR, the TSR of the S&P Life & Health Insurance index over the same period, our net income, and our principal financial measure for compensation purposes, Adjusted Return on Equity. CAP figures do not reflect the actual amount of compensation earned by or paid to our NEOs during the applicable year. For information regarding the decisions made by our Compensation Committee in regard to the NEOs’ compensation for each fiscal year, please see the Compensation Discussion & Analysis section of the proxy statement reporting pay for the fiscal years covered in the Pay Versus Performance table.

(1)The Principal Executive Officer (“PEO”) in fiscal years 2022, 2021, and 2020 is Daniel P. Amos.

(2)Adjustments have been made using stock option fair values as of each measurement date using the stock price as of the measurement date and the same assumptions that were used for stock options granted that year. Performance-based restricted share grant date fair values are calculated using ASC 718 at target-level performance. The Company’s valuation assumptions are described in Note 12, “Share-Based Compensation,” in the Notes to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2022. Adjustments have been made using the stock price and performance accrual modifier as of year-end and as of the date of vest, as applicable.

(3)The NEOs included in the calculation of average NEO compensation in fiscal years 2022, 2021, and 2020 are Max K. Brodén, Frederick J. Crawford, Eric M. Kirsch, and Audrey Boone Tillman.

(4)The peer group used for Total Shareholder Return is the S&P Life & Health Insurance index.

(5)Adjusted Return on Equity (AROE) is defined as Adjusted Earnings, excluding the impact of foreign currency, divided by Adjusted Book Value. AROE, Adjusted Earnings excluding the impact of foreign currency, and Adjusted Book Value are not calculated in accordance with GAAP. See Appendix A to this Proxy Statement for definitions for these non-GAAP financial measures and reconciliations to the most directly comparable GAAP measures.

(6)SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine the Compensation Actually Paid as reported in the Pay vs. Performance Table. CAP does not necessarily represent cash and/or equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules. In general, CAP is calculated as Summary Compensation Table total compensation adjusted to reflect certain changes in the fair market value of outstanding equity awards as of December 31 of the applicable year or, if earlier, the vesting date (rather than the grant date), and an adjustment for the aggregate value of service costs and prior service costs of pension benefits. No adjustment is made for dividends as dividends are factored into the fair market value of the award. The following table details these adjustments:

Year	Executive(s)	Summary Compensation Table Total	Subtract change in actuarial present value of pension	Subtract grant date fair value of stock awards granted during the fiscal year	Add aggregate value of service costs and prior service costs of pension benefits	Add year-end value of stock awards granted during the fiscal year	Add change in value of stock awards granted in prior years	Add change in value of vested stock awards granted in prior years	Compensation Actually Paid

Adjustment To PEO Compensation, Footnote [Text Block]

SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine the Compensation Actually Paid as reported in the Pay vs. Performance Table. CAP does not necessarily represent cash and/or equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules. In general, CAP is calculated as Summary Compensation Table total compensation adjusted to reflect certain changes in the fair market value of outstanding equity awards as of December 31 of the applicable year or, if earlier, the vesting date (rather than the grant date), and an adjustment for the aggregate value of service costs and prior service costs of pension benefits. No adjustment is made for dividends as dividends are factored into the fair market value of the award. The following table details these adjustments:
