Market‑Condition Stock‑Based Awards
Market-based Stock Units
During the three months ended March 31, 2025, the Company granted market-based stock units ("MSUs") for which the vesting conditions consist of market-based vesting conditions, determined by the Company's level of achievement of pre-established parameters relating to the performance of the Company's stock price as set by the Board as well as service-based vesting conditions. No MSUs were granted during the three months ended March 31, 2026. Vesting may range from 0% to 200% of the target MSUs granted, based on the achievement of specified market conditions. The
awards will be measured at each anniversary of the grant date and will vest following the completion of a performance period, which is generally three years unless shortened in the event of a change in control.
Performance Stock Units
During the three months ended March 31, 2026, the Company granted performance stock units ("PSUs") with market-based vesting conditions based on the Company's relative total shareholder return percentile ranking compared to the specified stock market index over the applicable performance period, subject to a continued service-based vesting requirement. No PSUs were granted during the three months ended March 31, 2025. The number of PSUs that may vest ranges from 0% to 250% of the target PSUs granted, based on the achievement of the specified market-based measures. The awards vest following the completion of a performance period, which is generally three years, subject to continued service-based vesting requirement, except that the awards may provide for prorated vesting upon a termination by the Company without cause or by the participant for good reason (as defined in the applicable award agreements). The Company may, at its discretion, settle vested PSUs in shares of common stock or in cash equal to the fair value of the shares. The PSUs are accounted for as equity-classified awards.
Compensation expense for MSUs and PSUs is based on the estimated value of the awards on the grant date, and is recognized over the period from the grant date through the performance period, regardless of level of achievement of the market conditions. The fair value of the awards was estimated based on a Monte Carlo simulation model, on a weighted average basis:
