Debt Disclosure [Text Block]	12. Liquidity In November 2007, we signed a revolving credit agreement, which expires in November 2012, with Wachovia Bank, NA to provide a credit line of up to $15.0 million in short term debt. The agreement is collateralized by all of our assets and requires us, among other things, to maintain certain financial performance levels relative to the fixed charge coverage ratio. This agreement was amended in June 2009 so that the ratio need only be maintained while we have less than $5.0 million in availability on the facility, and it was further amended in December 2009 to provide that our debt covenant ratio need only be maintained while we have less than $2.0 million in availability on the facility between March and June of each year. Interest on outstanding balances accrues at a rate of LIBOR plus 2.50% and is payable monthly. As of September 30, 2011 and November 8, 2011, we had no outstanding borrowings on our credit facility and we were in compliance with the terms of our agreement. In 2008, Wells Fargo Bank, NA acquired Wachovia Bank, NA. As a result, Wells Fargo Bank, NA, as successor to Wachovia Bank, NA, became our lender under the line of credit and is subject to all of the terms and conditions thereof.
