(2) Fair value or change in fair value, as applicable, of equity awards in the Compensation "Actually Paid" columns was determined by reference to (1) for RSU awards (excluding Total Shareholder Return “TSR” awards and other performance-based awards), closing price on applicable year-end date(s) or, in the case of vesting dates, the actual vesting price, (2) for performance-based RSU awards (excluding TSR Awards), the same valuation methodology as RSU awards above except year-end values are multiplied times the probability of achievement as of each such date (3) for TSR-based awards, the fair value calculated by a Monte Carlo simulation model as of the applicable valuation date(s). (3) For the portion of “Actually Paid” compensation that is based on year-end stock prices, the following prices were used: December 31, 2025 $61.80 (33.0% decrease from prior year), December 31, 2024 $92.25 (47.1% increase from prior year), December 31, 2023 $62.71 (35.6% increase from prior year), December 31, 2022 $46.25 (37.4% increase from prior year), December 31, 2021 $33.65 (7.58% reduction from prior year).
