The following information is relevant to the above table. The Reported Value of Equity Awards column includes the values originally reported in the Stock Awards column in the Summary Compensation Table (SCT). Fair value computations with respect to Absolute TSR PSUs and Relative TSR PSUs were computed in accordance with FASB ASC 718 using a Monte Carlo simulation. Fair value computations with respect to RSUs were computed based on the value of MGM stock on the date of computation, i.e., the end of the calendar year, the date of vesting, or the date of forfeiture, as the case may be. Footnote (c) below contains the names of the Named Executive Officers included in the averages. No information is presented in this table with regard to equity awards issued with respect to the annual incentive plan that were reported in the Non-Equity Incentive Plan Compensation column of the SCT, or with respect to RSUs issued in lieu of salary during 2020 that were reported in the Salary column of the SCT. With respect to Messrs. Murren and Rafiq, both of whom terminated in 2020, a portion of their PSUs became time-vested at termination, but the ultimate payout depended on satisfaction of the performance conditions of such awards; accordingly, their vesting date was treated as the end of the applicable performance period. With respect to Messrs. Murren and Rafiq, both of whom terminated in 2020, a portion of their RSUs became time-vested at termination but were subject to payout on the original vesting dates; since payout on such dates was subject to satisfaction of restrictive covenants that were part of the original terms of the award, the vesting date was treated as the original payment date. A portion of Mr. Murren’s $7 million RSU grant in 2020 was cash settled in 2020; since the original grant was reported in the Stock Award column, the cash settlement was not treated separately from the portion settled in stock.
(C) | Amounts represent the average of the amounts reported for the Company’s NEOs as a group (excluding Mr. Hornbuckle and Mr. Murren) in the “Total” column of the Summary Compensation Table in each applicable year. The names of each of the NEOs included for purposes of calculating the average amounts in each applicable year are as follows: for 2023 and 2022, Messrs. Halkyard, Sanders, Fritz, and McManus; for 2021, Messrs. Halkyard, Sanders, Mandadi, and McManus; and for 2020, Messrs. Sanders, McManus, and Rafiq.
(D) | Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period beginning December 31, 2019, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.
(E) | Represents the weighted peer group TSR of the companies included in the Dow Jones U.S. Gambling Index.
(F) | Represents the amount of net income reflected in the Company’s audited financial statements for the applicable year.
(G) | Based on the S&P500 Constituents as of January 1 of relevant year.
