The grant date fair value per share for these shares was $37.74 (the closing price on the grant date). We also granted 32,307 shares of time-based restricted stock to members of the Board of Directors with a grant date fair value per share of $42.56 (the closing price on the grant date).

The fair value of stock options was estimated using the Black-Scholes option pricing model with the following assumptions:

Risk-free interest rate	0.8	%
