(3) In accordance with Item 402(v) requirements, the fair values of unvested and outstanding equity awards were remeasured as of the end of each fiscal year, and as of each vesting date, during the years displayed in the tables below. For PSUs with a relative TSR metric, the fair values as of each measurement date (prior to the end of the performance period) were determined using a Monte Carlo simulation pricing model, with assumptions and methodologies that are generally consistent with those used to estimate fair value at grant under U.S. GAAP. The range of estimates used in the Monte Carlo calculations are as follows: (i) for 2022, volatility between 19%-41% 30%-32% 0.4%-0.7%; 22%-24% 4.3%-4.6%. 10-K. non-PEO S-K.
