Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plan	EMPLOYEE BENEFIT PLAN The Company has a 401(k) retirement savings plan in which substantially all of its employees may participate. The plan includes a provision for the Company to match a percentage of the employee’s contributions at a rate determined by the Company’s Board of Directors. In 2015, 2014 and 2013 the Company’s contributions were approximately $5.7 million, $5.1 million and $2.8 million, respectively. The increase in the Company's matching contributions in 2015 was due to increased participation in the plan. The increase in 2014 was due to changes, approved by the Company's Board of Directors, to the rate of Company match as well as increased participation in the plan. The Company does not provide health care benefits to retired employees.
