Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Note 9 - 401(k) Retirement Benefit Plan We maintain a defined contribution 401(k) plan covering substantially all employees. Employees can contribute a portion of their salary or wages as prescribed under Section 401(k) of the Internal Revenue Code and, subject to certain limitations, we may, at the discretion of our Board of Directors, authorize an employer contribution based on a portion of the employees' contributions. Since January 2010, we have matched 50% on the first 4% contributed by an employee, or a maximum of 2% of the employee’s income. For 2013 and 2012, we contributed $99 and $243, respectively, to the 401(k) plan.
