The weighted-average fair value was based on the fair value of stock options granted during the period.
(2)
The expected volatility was estimated using the average historical volatility of selected peer companies.
(3)
The risk-free interest rate was estimated based on the yield on U.S. Treasury zero-coupon issues.
(4)
The expected dividend yield represents a constant dividend yield applied for the duration of the expected term of the award.
(5)
For awards subject to service-based vesting, the expected term was estimated using the simplified method detailed in SEC Staff Accounting Bulletin No. 110, for performance-contingent awards the expected term represents an output from the lattice model.
