4. Method of estimating the fair value of stock options
The fair value of the 2009 Stock Options granted during the fiscal year under review was estimated using following method.
(1) Method of valuation used: Black-Scholes option pricing model
(2) Main assumptions used and method of valuation
2009 Stock Options 2009 Stock Options
Expected share price volatility (Note 1) 33.3% 36.4%
Expected life (Note 2) 10 years 3.45 years
Expected dividend (Note 3) Dividend yield 1.26% Dividend yield 1.50%
Risk-free interest rate (Note 4) 1.40% 0.31%
Notes: 1. Calculated based on historical share price data prior to the grant date over a period equivalent to the expected life.
2. Owing to insufficient accumulated data, an appropriate estimate is problematic. Consequently, the midpoint of the available exercise period has been used as the
estimated life.
3. For the 2009 Stock Options, this was calculated based on the actual dividend applicable to the fiscal year ended March 31, 2009.
4. Yield of government bonds corresponding to the expected life of the options.
5. Method of estimating the number of vested stock options
In principle, owing to the difficulty of appropriately estimating the forfeited number of stock options for future periods, estimation of the vested
number is based on actual forfeitures in prior periods.
