（b）The company made an award of 1000 share options to each of its 100 employees working in the sales department. The share option would vest at the end of 20 X 6， provided that the employees remained in the employ of the company till the date of vest， and provided that the company‘s earnings per share （EPS） increased by at least an average of 10% over the three-year period. The exercise price of each option was ￥15， but it would drop ；to ￥10 if EPS increased by an average of 15% or more.
On the grant date， the company estimated that the fair value of the share option was ￥25 per option if the exercise price was ￥15； ￥30 if the exercise price was ￥10.
In the year ended December 31， 20 X 4， the company‘s EPS increased by 16% and the management forecasted similar growth for the next two years. However， during 20 X 5， EPS increased by just 12% resulting in an average for the two-year period of 14%. Therefore， the management expected that EPS would continue to increase at 14% for 20 X 6. In the year 20 X 6， EPS of the company increased by 17% resulting in an average for the three-year period of 15%.
During 20 X 4， 10 employees left the company and the management predicted that a total of 35 employees would leave by the end of 20 X 6. 15 employees departed during 20 X 5， and hence 60 employees were expected to remain. By the end of 20 X 6， a further 5 employees had left.
