This is the estimated percentage of options granted that are expected to be forfeited or cancelled before becoming fully vested. This estimate is based on historical experience at the time of valuation and reduces expenses ratably over the vesting period. An increase in the forfeiture rate will decrease compensation expense. This estimate is evaluated periodically based on the extent to which actual forfeitures differ, or are expected to differ, from the previous estimate.
