The TMCC regularly considers the appropriate time horizon for the performance measures used in the compensation plan for our NEOs. The TMCC believes that using multiple-year vesting for the Relative TSR PSUs appropriately balances the one-year performance period for the annual bonus and the three-year vesting period for the time-based RSUs and Financial PSUs.

We believe total shareholder return (“TSR”) is an objective, external benchmark for evaluating shareholder value creation. It serves as a valuable complement to our internal performance metrics, including growth (ARR) and profitability (non-GAAP EBIT), designed for a balanced and comprehensive assessment of our financial success.
