| Pay vs Performance Disclosure, Table | PAY VERSUS PERFORMANCE As discussed in the Compensation Discussion and Analysis above, the Compensation & Human Resources Committee has implemented an executive compensation program designed to link a substantial part of each executive’s realized compensation to the achievement of Moody’s financial and operational objectives and to the individual executive’s performance as well as to align executives’ pay with changes in the value of stockholders’ investments. As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, Year Summary Compensation Paid to Summary Compensation Paid to Robert Fauber (1)(2) Average Average NEOs (1)(3) Value of Initial Fixed Net MCO EPS for Moody’s Russell 2023 — — $ 14,387,659 $23,499,543 $ 2,887,540 $2,635,366 $ 170 $ 143 $ 1,607 $ 9.90 2022 — — $ 11,619,773 ($ 4,692,319 ) $ 3,186,695 ($1,700,521 ) $ 120 $ 116 $ 1,374 $ 8.57 2021 — — $ 9,750,157 $21,584,082 $ 3,056,066 $7,117,461 $ 167 $ 136 $ 2,214 $ 12.29 2020 $ 17,270,662 $ 22,264,987 — — $ 3,869,500 $5,653,058 $ 123 $ 99 $ 1,778 $ 10.15 (1) For each year, “Compensation Actually Paid” reflects the Summary Compensation Table (SCT) total, for the relevant Named Executive Officer(s) less Non-Qualified adding to this • The fair value at the end of the year of equity compensation granted during the year that remained unvested at the end of the year; • The fair value as of the vesting date of equity compensation granted and vested in the same year; • The change in fair value as of the vesting date, measured from the prior year-end, • The change in fair value at year-end, year-end, • The pension value attributable to service in the year. For the other NEOs, each of the above figures is calculated and presented on an average basis. As a result, “Compensation Actually Paid” does not reflect the value that was or may actually be realized by the NEOs. Equity values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values of RSUs did not materially differ from those disclosed at the time of the grant. In calculating the year-over-year change in the value of unvested option awards as well as the change in value to mid-year re-valued • Stock price: mid-year year-end year-end • Expected life: in-the-money out-of-the-money • Stock price volatility: • Risk-free rate: • Dividend yield: In valuing performance share awards, we calculated the fair value of unearned or earned but unvested awards, based on probable and/or final payout factors, as of the relevant measurement date. (2) The amounts deducted and added in calculating the “Compensation Actually Paid” for Mr. Fauber for 2021 through 2023 and Mr. McDaniel for 2020 are as follows: 2023 2022 2021 2020 Reported SCT Total Compensation $ 14,387,659 $ 11,619,773 $ 9,750,157 $ 17,270,662 Subtract: Equity Award Values Reported in the SCT $ (10,999,984 ) $ (9,000,110 ) $ (6,400,149 ) $ (10,349,742 ) Add: Year End Fair Value of Equity Awards Granted in the Year $ 16,092,220 $ 4,518,780 $ 12,983,536 $ 8,552,443 Add: Value as of Vesting Date of Equity Awards Granted and Vested in the Year $ 0 $ 0 $ 0 $ 3,219,138 Add/Subtract: Year over Year Change in Fair Value of Outstanding and Unvested Equity Awards Granted in Prior Years $ 3,864,109 $ (10,255,631 ) $ 5,264,759 $ 3,080,592 Add/Subtract: Change in Fair Value From Prior Year End to Vesting Date of Equity Awards Granted in Prior Years that Vested in the Year $ 342,536 $ (1,747,485 ) $ 2,847 $ 5,832,054 Subtract: Fair Value of Equity Compensation Forfeited in Current Fiscal Year Determined at End of Prior Fiscal Year $ 0 $ 0 $ 0 $ (2,146,411 ) Subtract: Pension Values Reported in the SCT $ (366,643 ) $ 0 $ (225,904 ) $ (3,444,752 ) Add: Pension Service Cost Attributable to Year $ 179,646 $ 172,355 $ 208,836 $ 251,004 Compensation Actually Paid $ 23,499,543 $ (4,692,319 ) $ 21,584,082 $ 22,264,987 (3) For 2023, other NEOs include Messrs.
