Postemployment Benefits [Abstract]
EMPLOYEE BENEFIT PLAN - Note 10	10. EMPLOYEE BENEFIT PLAN *401(k) Savings Plan* In April 1991, the Company adopted a 401(k) savings plan (the "Savings Plan") covering substantially all of its U.S. employees. Eligible employees may contribute to the Savings Plan from their compensation up to the maximum allowed by the Internal Revenue Service. In January 2007, the Company reactivated the employer matching contribution. The matching contribution is 100% of each employee's contributions in each year, not to exceed $1,500 per annum. The matching expense in 2016, 2015 and 2014 was $0.9 million, $0.7 million and $0.4 million, respectively. The Savings Plan does not allow employee contributions to be invested in the Company's common stock.

The entire disclosure for postemployment benefits, which may include supplemental unemployment benefits, obligations recognized for all types of benefits provided to former or inactive employees, their beneficiaries, and covered dependents after employment but before retirement. Disclosure may also include discussion that an obligation for postemployment benefits is not accrued in accordance with regulation only because the amount cannot be reasonably estimated.
