Notes to Financial Statements
Compensation Related Costs, General [Text Block]	11. DEFERRED PROFIT SHARING EMPLOYEE BENEFIT PLAN We have a deferred profit sharing and savings plan under which all of our employees with at least six months of service are eligible to participate. Employees may contribute a percentage of their annual compensation up to the maximum amount allowed by the Internal Revenue Code. We may make discretionary contributions as determined by a committee of our Board of Directors. We made contributions of $0.7 million in 2016, $0.8 million in 2015, and zero in 2014 to the profit sharing and savings plan.

The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.
