Share-Based Compensation [Abstract]

Share-Based Compensation Policy

We provide for various forms of share-based compensation awards to our employees and non-employee directors. With the exception of stock options, the fair value of our awards is equal to the closing stock price of IDEXX common stock on the date of grant. We calculate the fair value of our stock option awards using the Black-Scholes-Merton option-pricing model. Share-based compensation expense is recognized net of estimated forfeitures, on a straight-line basis over the requisite service period of the award.
