Explanation of Responses:
( 1 )On July 21, 2020, the reporting person was granted a target number of 6,433 performance units and can earn up to a maximum of 32,165 performance units subject to satisfaction of share price targets ranging from $260 to $300 over a performance period from July 21, 2020 to July 20, 2023. In addition, all performance units are subject to the achievement of a business operating goal with a performance period through December 31, 2021, as determined by the Compensation Committee of the Company. 75% of the performance units are subject to time-based vesting and require service through July 20, 2023, and the remaining 25% of the performance units are subject to time-based vesting and require service through July 20, 2024. Once vested, the performance units convert into shares of common stock on a 1-for-1 basis and the resulting shares, net of tax withholdings, have a post-vesting sales restriction period of one year.
