SHARE-BASED COMPENSATION PLANS
All share-based compensation for employees and directors is granted under the 2019 Long-Term Incentive Plan, as amended (the "Plan"), which has been approved by our shareholders. The purpose of the Plan is to attract and retain individuals of exceptional talent and encourage these individuals to acquire a vested interest in our success and prosperity. The awards that may be granted under this program include non-qualified stock options, stock appreciation rights, restricted stock and restricted share units. Restricted shares are generally service-based, requiring a certain length of service before vesting occurs, while restricted share units can be either service-based or performance-based. Performance-based restricted share units also require a certain length of service until vesting, but contain an additional performance feature, which can vary the amount of shares ultimately paid out based on certain performance criteria specified in the Plan or award. Performance share units that are based on relative total shareholder return are subject to a market condition. Awards granted under the Plan vest and may be exercised and/or sold from one year to ten years after the date of grant based on a vesting schedule. As of December 31, 2025, there were 1.7 million shares available to be granted.

Share-based compensation expense was as follows (in millions):

As of December 31, 2025, unrecognized share-based compensation expense was $67.8 million, and the weighted-average period over which the expense is expected to be recognized was approximately 1.4 years. Proceeds from the exercise of stock options are credited to ordinary shares.

Non-vested Relative Total Shareholder Return Performance Share Units

The fair value of the RTSR performance share units is determined using the Monte Carlo pricing model as the number of shares to be awarded is subject to a market condition. The valuation model considers a range of possible outcomes, and compensation cost is recognized regardless of whether the market condition is actually satisfied.

The assumptions used in estimating the fair value of the RTSR performance share units granted during each year were as follows:
 Year Ended
 December 31, 2025December 31, 2024December 31, 2023
Dividend yield4.4 %3.5 %3.0 %

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
