Time-vested RSUs are valued at the closing prices of the applicable class of the company’s ordinary shares on each applicable valuation date. Time-vested SARs are valued using the Black-Scholes option pricing model, and for each valuation date, the fair value was determined using the closing price of the applicable class of the company’s ordinary shares on such date, the volatility and risk-free rate assumptions that were in effect for the given year and the expected life assumption that was in effect on the original grant date of the SARs, less the time that has elapsed since the grant date.
