The Principal Executive Officer and NEOs for the applicable years were as follows:
2022: Garrick J. Rochow served as the President and CEO of CMS and Consumers for the entirety of 2022 and the other NEOs of CMS and Consumers were: Rejji P. Hayes; Brandon J. Hofmeister; Shaun M. Johnson; and Brian F. Rich.
2021: Garrick J. Rochow served as the President and CEO of CMS and Consumers for the entirety of 2021 and the other NEOs of CMS and Consumers were: Rejji P. Hayes; Jean-Francois Brossoit; Shaun M. Johnson; and Brian F. Rich.
2020: Garrick J. Rochow assumed the role of the President and CEO of CMS and Consumers on December 1, 2020 and Patricia Poppe served as President and CEO of CMS and Consumers during 2020 through Poppe’s December 1, 2020 resignation. The other NEOs of CMS and Consumers for 2020 were: Rejji P. Hayes; Jean-Francois Brossoit; Catherine A. Hendrian; and Brian F. Rich.
(2)
Amounts reported in this column represent (i) the total compensation reported in the Summary Compensation Table for the applicable year in the case of Rochow and Poppe and (ii) the average of the total compensation reported in the Summary Compensation Table for the applicable year for the NEOs of CMS and Consumers reported for the applicable year other than the Principal Executive Officers for such years.
(3)
To calculate compensation actually paid, adjustments were made to the amounts reported in the Summary Compensation Table for the applicable year. A reconciliation of the adjustments for Rochow, Poppe, and for the average of the other NEOs is set forth following the footnotes to this table.
(4)
Pursuant to rules of the SEC, the comparison assumes $100 was invested on December 31, 2019. Historic stock price performance is not necessarily indicative of future stock price performance. See the CD&A for further information regarding how TSR is calculated for purposes of the long-term incentive program.
(5)
The TSR Peer Group is the same peer group utilized in the annual report (10-K) for 2022 and consists of utilities listed in the Standard & Poor’s 400 Utilities Index, an independently prepared index that consists of companies in the utilities industry.
(6)
As noted in the CD&A, for 2022, the Compensation Committee determined that adjusted EPS continues to be viewed as a core driver of the CMS’s performance and stockholder value creation and, accordingly, was utilized as a component for both the Annual Incentive and LTI Awards. Adjusted EPS is a non-GAAP financial measure that represents EPS adjusted to exclude gains or losses on asset sales which have been excluded from adjusted EPS or are greater than or equal to 2% of adjusted EPS; changes in accounting principles resulting from new or revised accounting standards not included in the budget; large restructuring and severance expenses greater than $5 million or equal to $0.01 of EPS; legal and settlement costs or gains related to previously sold assets; regulatory recovery for prior year changes; changes in legacy tax reform; changes in federal tax policy; loans sold from discontinued operations; 3rd party costs related to the Business Optimization initiative (greater or equal to $0.01 of EPS); and unrealized gains or losses, recognized in net income, from mark-to-market adjustments related to CMS NorthStar’ interest expense. See Appendix for a reconciliation of GAAP EPS to Adjusted EPS.
(7)
2021 Net Income includes the proceeds from the sale EnerBank, a one-time event excluded from Adjusted Earnings Per Share.
(8)
Effective December 1, 2020, Poppe voluntarily resigned from the Corporation from her position as President and CEO of CMS and Consumers. As a result, Poppe forfeited any outstanding long-term incentive awards, her annual incentive award and any unvested supplemental retirement awards.

Compensation Actually Paid vs. Total Shareholder Return [Text Block]    
Relationship Between Pay and Performance
We believe the compensation actually paid, as calculated in accordance with SEC disclosure rules, in each of the years reported above and over the three-year cumulative period are reflective of the Compensation Committee’s emphasis on “pay-for-performance” as the compensation actually paid fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our Annual Incentive Plan and long-term incentive program, including our adjusted EPS performance.
Compensation Actually Paid Versus TSR
The following chart illustrates the relationship between CMS’s three-year TSR to the compensation actually paid to the individuals serving as Principal Executive Officer during the applicable year and the average for the other NEOs. For 2021 and 2022, the compensation actually paid to the Principal Executive Officer and other NEOs was relatively aligned with CMS’s consistent TSR performance year-over-year. The fluctuation between 2020 and 2021 for Rochow is primarily due to the increase in compensation year-over-year as a result of Rochow’s promotion to CEO of CMS and Consumers in December 2020 and the fact that Rochow’s 2020 compensation reflected Rochow’s role at CMS and Consumers prior to promotion. Similarly, the compensation actually paid to Poppe during 2020 reflects the forfeiture of Poppe’s long-term incentive awards in connection with Poppe’s resignation.

Compensation Actually Paid vs. Net Income [Text Block]    
Relationship Between Pay and Performance
We believe the compensation actually paid, as calculated in accordance with SEC disclosure rules, in each of the years reported above and over the three-year cumulative period are reflective of the Compensation Committee’s emphasis on “pay-for-performance” as the compensation actually paid fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our Annual Incentive Plan and long-term incentive program, including our adjusted EPS performance.
Compensation Actually Paid Versus Net Income
Because a significant percentage of compensation is delivered in the form of equity awards with vesting tied to TSR, EPS growth; and continued service, our executive compensation program is less impacted by fluctuations in net income. The following chart illustrates the relationship between net income and the compensation actually paid to the individuals serving as Principal Executive Officer during the applicable year and the average compensation actually paid for the other NEOs.

Compensation Actually Paid vs. Company Selected Measure [Text Block]    
Relationship Between Pay and Performance
We believe the compensation actually paid, as calculated in accordance with SEC disclosure rules, in each of the years reported above and over the three-year cumulative period are reflective of the Compensation Committee’s emphasis on “pay-for-performance” as the compensation actually paid fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our Annual Incentive Plan and long-term incentive program, including our adjusted EPS performance.
Compensation Actually Paid Versus Adjusted EPS
As discussed above, adjusted EPS is viewed as a core driver of CMS’ performance and stockholder valuation creation and, accordingly, was used as a component in both the Annual Incentive and LTI Awards. Because the compensation actually paid, as calculated per SEC disclosure rules, is most greatly impacted by stock price fluctuations, the impact of year-over-year fluctuations in adjusted EPS performance has less of an impact on compensation actually paid as compared to stock price performance. As noted in the chart below, while adjusted EPS increased between 2021 and 2022, the compensation actually paid to the other
NEOs declined, which was correlated with the decline in TSR year-over-year. In addition, the compensation actually paid in 2020 and, in the case of Rochow, the change from 2020 to 2021, was also a result of the change in CEO role that occurred in December 2020 and the compensation adjustments and forfeitures relating to such change.

Tabular List [Table Text Block]    
Performance Measures Used to Link Performance and Compensation Actually Paid to the NEOs
The following is a list of financial performance measures, which in the Company’s assessment represent the most important financial performance measures used by the Company to link compensation actually paid to the NEOs for 2022. Please see the CD&A for further information regarding how each of these measures is calculated and how they are used in the Company’s executive compensation program, including the calculation of GAAP EPS to Adjusted EPS for purposes of the Annual Incentive Awards and the LTI program. Our 2022 executive compensation program utilized financial metrics and supplemented those metrics in the Annual Incentive program with additional metrics tied to our operational performance, with goals relating to employee safety, culture, customer experience, electric reliability, waste elimination from cost reductions and methane emission reductions.
