Compensation And Retirement Disclosure [Abstract]
Retirement Savings Plan	NOTE O – Retirement Savings Plan We sponsor a 401(k) retirement savings plan for our employees. Employees can contribute up to 100% of their compensation, subject to the limits established by law. In 2018, we increased our match to 50% of the employee’s contribution up to the first 6% of pre-tax annual compensation. A portion of our match is in company stock, which is purchased from the open market by our plan provider and immediately deposited into the employee’s 401(k) account, which resulted in $1.2 million of stock-based compensation expense in 2018. Additionally, we make statutory contributions to retirement plans as required by local foreign government regulations. Our total contributions to the plan were $2.9 million, $1.6 million and $1.4 million for the years ended December 31, 2018, 2017 and 2016, respectively.
