(b) Fair value of share options and assumptions
The fair value of services received in return for share options
granted is measured by reference to the fair value of share options
granted. The estimate of the fair value of the share options granted is
measured based on Black Scholes Model. The contractual life of the
share option is used as an input into this model.

value measurement of the services received. There were no market
conditions associated with the share option grants.

購股權的公允價值及假設
作為授出購股權代價而獲得的服務公允價值，乃
參照已授出購股權的公允價值計算。已授出購股
權的估計公允價值乃根據柏力克舒爾斯模式計
算。此模式亦會計及購股權的合約年期。
預期波幅乃參考本公司過往與預期購股權有效期
長度相同之期間的每日歷史波幅作出。預期股息
乃按過往股息而定。用作計算的主觀假設如有更
改，可能重大影響公允價值的估計。
購股權是基於已提供服務的條件授出。計算所獲
提供服務於授出日期之公允價值時，並無考慮該
項條件。授出購股權與市況無關。
