Common use of Vesting Formula Clause in Contracts

Vesting Formula. Target Number of mPRSUs x (100% + ((LRCX TSR % – Index TSR %) x 2)) = mPRSUs vested (subject to the maximum in the Payout Range) ◦ Target Number of mPRSUs is vested if the LRCX TSR % equals the Index TSR % ◦ Number of mPRSUs vested increases by 2% of target for each 1% that the LRCX TSR % exceeds the Index TSR % ◦ Number of mPRSUs vested decreases by 2% of target for each 1% that the LRCX TSR % trails the Index TSR % ◦ The result of the Vesting Formula is rounded down to the nearest whole number • LRCX TSR % (LRCX 50-trading day average closing price as of the last trading day of the Performance Period – LRCX 50-trading day average closing price on the trading day immediately prior to the beginning of the Performance Period) ÷ (LRCX 50-trading day average closing price on the trading day immediately prior to the beginning of the Performance Period) x 100 • Index TSR % Exhibit A – Market-Based Performance Restricted Stock Unit Award Agreement (Index 50-trading day average closing price as of the last trading day of the Performance Period – Index 50-trading day average closing price on the trading day immediately prior to the beginning of the Performance Period) ÷ (Index 50-trading day average closing price on the trading day immediately prior to the beginning of the Performance Period) x 100 • Notes: ▪ The LRCX TSR % calculation excludes any dividends paid on the Company’s common stock. ▪ All Index TSR % calculations are based on the companies traded on the Index as of the applicable dates o E.g., The Index is used as of the applicable dates even if companies are added / removed from the Index during the Performance Period. ▪ The Company’s relative performance is determined using calculations based on the 50-trading day average closing price methodology for all TSR calculations. ▪ In the event of a Corporate Transaction, the closing price of the Company’s common stock as of the closing date of the Corporate Transaction is used to convert the sum of the “performance pro rata” and “target pro rata” number of Shares into the Cash Award. ▪ If the Index is no longer traded / calculated, the Company’s relative performance is determined using calculations based on the companies included in the Index at the time trading / calculation last occurred. The Compensation Committee will calculate the Index TSR % in the manner that most closely approximates the Index in its sole discretion.
