RETIREMENT PLAN [Abstract]
Compensation and Employee Benefit Plans [Text Block]	RETIREMENT PLAN We maintain a 401(k) retirement plan that covers all eligible US employees. Employees are eligible to contribute amounts to the plan subject to certain minimum and maximum limitations. We match employee contributions on a discretionary basis as determined by the Board of Directors. We made $350,000, $235,000 and $171,000 of matching cash contributions in 2011, 2010 and 2009, respectively. Going forward, we intend to continue matching 50% of the first 4% of employee’s compensation contributed to the plan, subject to our financial performance. Eligible employees of our Indian subsidiaries are covered by the Provident Fund (the “Plan”) and the Payment of Gratuity Act (the “Act”). Both the Plan and the Act are unfunded plans. Contributions to the Plan are based on a fixed percentage of eligible employees’ salaries. During the year ended December 31, 2011 we made contributions of $181,000 to cover the estimated benefits provided during the current year which are administered by the Indian government. The Act provides for certain benefits to be paid to eligible employees upon termination of employment. As of December 31, 2011 and 2010 we had an accrued benefit obligation relating to the Act of $214,000 and $447,000, respectively. During the year ended December 31, 2011 and 2010 we made Act payments of $191,000 and $21,000, respectively.
