Stock-Based Compensation | Note 15. Stock-Based Compensation The Company measures compensation expense for all stock-based awards based on the estimated fair values on the date of the grant. Stock options generally vest ratably over three years from the date of grant and expire 10 years from the date of grant. Restricted stock awards generally vest ratably over three years from the date of grant and contain no other service or performance conditions. The Company's policy is to recognize stock-based compensation expense on a straight-line basis over the requisite service or vesting period. Forfeitures for stock options and restricted stock awards are recognized as they occur.
