Stock Options / RSUs
Eligible participants may receive (i) stock options, (ii) RSUs or (iii) a combination of both stock options and RSUs. The fair value of each of the Company's stock option and RSU awards is expensed on a straight-line basis over the required service period, which is generally the 3-year vesting period. Beginning with the 2024 grant year, for stock options and RSUs granted to retirement eligible employees, the Company recognizes expense over the period during which an employee is required to provide service in exchange for the award, which is generally 12 months. For awards granted to retirement eligible employees prior to 2024, the Company recognized expense for the fair value at the grant date.
The average fair value of the stock options granted is determined using the Black Scholes option pricing model. The following assumptions were used during the year ended December 31:
202520242023
Dividend yield0.95 %1.11 %1.50 %
Volatility27.26 %29.99 %29.37 %
Risk-free rate of return4.30 %4.00 %3.62 %
Expected life in years4.84.84.8
A description of the significant assumptions used to estimate the fair value of the stock option awards is as follows:
Dividend yield - The Company determines the dividend yield based upon the expected quarterly dividend payments as of the grant date and the current fair market value of the Company's shares.
Volatility - The expected volatility is based on a weighted average of the Company's implied volatility and the most recent historical volatility of the Company's shares commensurate with the expected life.
Risk-free rate of return - The Company applies a yield curve of continuous risk-free rates based upon the published US Treasury spot rates on the grant date.
Expected life in years - The expected life of the Company's stock option awards represents the weighted-average of the actual period since the grant date for all exercised or canceled options and an expected period for all outstanding options.

At December 31, 2025, there was $15.9 million of total unrecognized compensation cost from stock option arrangements granted under the plan, which is primarily related to unvested shares of non-retirement eligible employees. The aggregate intrinsic value of options exercised during the years ended December 31, 2025 and 2024 was $178.1 million and $210.2 million, respectively. Generally, stock options expire ten years from their date of grant.

Performance Shares
The Company has a Performance Share Program (PSP) for key employees. The program provides awards in the form of PSUs based on performance against pre-established objectives. The annual target award level is expressed as a number of the Company's ordinary shares based on the fair market value of the Company's stock on the date of grant. All PSUs are settled in the form of ordinary shares.
PSU awards are earned based 50% upon a performance condition, measured by relative Cash Flow Return on Invested Capital (CROIC) to the S&P 500 Industrials Index over a 3-year performance period, and 50% upon a market condition, measured by the Company's relative total shareholder return (TSR) as compared to the TSR of the S&P 500 Industrials Index over a 3-year performance period. Beginning with the 2024 grant year, for PSUs granted to retirement eligible employees, the Company recognizes the expense over the period during which an employee is required to provide service in exchange for the award, which is 12 months. For awards granted to retirement eligible employees prior to 2024, the expense was recognized over the 3-year performance period. The fair value of the market condition is estimated using a Monte Carlo simulation model in a risk-neutral framework based upon historical volatility, risk-free rates and correlation matrix.
The following table summarizes PSU activity for the maximum number of shares that may be issued for the years 2025, 2024 and 2023:

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.
