Stock-Based Compensation	NOTE 7. STOCK-BASED COMPENSATION Stock-based compensation granted under our Company’s stock plans is expensed in tranches over the vesting period. Options and non-performance based grants generally vest equally over a three or four-year period and the options have a maximum term of ten years. For the nine months ended September 30, 2016, we granted 216,973 stock incentive units at a grant price between $80.98 and $92.56. Each performance unit and restricted stock unit represents a contingent right to receive one share of common stock as of the vesting date. Such common stock may be subject to forfeiture for the payment of any required tax withholding.
