Retirement Benefits [Abstract]
RETIREMENT SAVINGS PLAN	RETIREMENT SAVINGS PLAN The Company maintains a defined contribution plan (the “Retirement Savings Plan”) pursuant to Section 401 of the Internal Revenue Code (the “Code”) which covers active regular employees. Employees are eligible under the Retirement Savings Plan immediately upon hire, and pre-tax contributions are allowed up to the limits set by the Code. Through December 31, 2018, the Company matched up to 3% of an employee’s eligible pre-tax Retirement Savings Plan contributions up to certain Code limits. Through December 31, 2018, employees vested in Company contributions over a three-year period. Beginning January 1, 2019, the Company contributes 3% of an employee's compensation to the plan that are fully vested after the employee has been with the company for two years. The Company may change this percentage at its discretion, and, in addition, the Company could decide to make discretionary contributions in the future. The Company contributed $647,000, $764,000, and $682,000 to the Retirement Savings Plan for the 2018, 2017, and 2016 plan years, respectively.
