Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | Pay vs. Performance The following table sets forth the compensation for our Chief Executive Officer (“CEO”) and the average compensation for our other non-CEO named executive officers (“NEOs”), both as reported in the Summary Compensation Table (“SCT”) and with certain adjustments to reflect the compensation actually paid (“CAP”) to such individuals, as defined under SEC rules, for the years 2022, 2021, and 2020. The table also provides information on our cumulative total shareholder return (“TSR”) for both our Class A and Class B Common Stock; the cumulative TSR of our peer group; Net Earnings; and the Company-Selected Measure (“CSM”), Non-GAAP Adjusted Earnings from Operations (“EFO”), over such years in accordance with SEC rules.

(1) | SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine compensation actually paid as reported in the Pay versus Performance Table. Compensation actually paid, generally, is calculated as Summary Compensation Table total compensation adjusted to include the fair market value of equity awards as of the end of the fiscal year for the applicable year or, if earlier, the vesting date (rather than the grant date). We do not offer pension plan benefits therefore, there was not a change in pension value for any of the years reflective in this table. To calculate CAP, the following amounts were deducted from and added to SCT total compensation:
