Named Executive Officers, Footnote | The totals reflected align with (i) for the PEO, the amounts of total compensation reported in the Summary Compensation Table for the PEO, and (ii) for the Non-PEO NEOs, the average of the amounts of total compensation reported in the Summary Compensation Table for such Non-PEO NEOs, as shown on page 71. Mr. Wilson served as Chair, President and CEO for each fiscal year reported and is therefore represented as the PEO for each such fiscal year. The Non-PEO NEOs column represents Allstate’s NEOs for each respective year. The employees comprising the Non-PEO NEOs for each year are noted below:

Peer Group Issuers, Footnote | These totals were calculated in the same manner as required under Item 201 (e) of Regulation S-K. The Total Shareholder Return (TSR) represents the cumulative return on a fixed investment of $100 in the common stock (including reinvested dividends) of (a) the company and (b) its peer group, respectively, for the period starting January 1, 2020, through the last day of the listed fiscal year. Our peer group used for the TSR calculation is the same as our compensation benchmarking peer group: AFLAC Inc.; American International Group, Inc.; AON plc; Chubb Limited; The Hartford Financial Services Group, Inc.; Humana Inc.; Manulife Financial Corporation; Marsh & McLennan; MetLife, Inc.; The Progressive Corporation; Prudential Financial Inc.; and The Travelers Companies Inc. |  |  |  |  |  |  |  |

Adjustment To PEO Compensation, Footnote | Compensation actually paid (CAP) has been calculated in accordance with Item 402(v) of Regulation S-K. The amounts do not reflect the actual amount of compensation earned, realized or received by the company PEO and Non-PEO NEOs. These amounts reflect the Summary Compensation Table Total with certain adjustments as described below, for the years represented. Equity values for purposes of calculating CAP were determined in accordance with FASB ASC Topic 718. The valuation methodologies and assumptions used to calculate the equity values included in CAP are based on our grant date fair value of the equity awards as disclosed in the company’s audited financial statements for the applicable fiscal year.

Tabular List, Table | Financial Performance Measures: The Allstate executive compensation programs reflect the pay-for-performance culture and supports shareholder alignment while also incentivizing our executives as noted throughout the CD&A beginning on page 48. For the annual and LTI programs, the Committee uses performance measures that (1) align with the company’s strategy, operating principles and priorities and shareholder interest, (2) support the achievement of corporate goals and (3) reflect the company’s overall performance. The most important performance measures, in our assessment, used to link CAP of our NEOs for the most recently completed fiscal year to the company’s performance are as follows:
Performance Net Income (PNI)
Performance Net Income Return on Equity (PNI ROE)
Total Premiums
Relative Total Shareholder Return (TSR)
