Employee Benefits [Abstract]
Employee Benefits	Note 8 Employee Benefits The Company sponsors a Section 401(k) plan (the “Plan”) covering substantially all its eligible U.S. employees. The Plan entitles eligible employees to make contributions to the Plan after meeting certain eligibility requirements. Contributions are limited to the maximum contribution allowances permitted under the Internal Revenue Code. The Company matches 50.0% of contributions on the first 6.0% of the participant’s eligible compensation. The Company will give a minimum match of $1,500 to participants who average a minimum 6.0% deferral contribution rate per plan year. In addition, the Company has several other U.S. and non-U.S. defined contribution plans covering eligible U.S. and non-U.S. employees, respectively. For the years ended December 31, 2017, 2016 and 2015, the Company expensed $2,360, $1,175 and $956, respectively, for matching contributions to defined contribution plans.
