Credit Facility, Long-Term Debt and Debt Covenants Disclosure [Text Block]	(6) Credit Facility, Long-Term Debt and Debt Covenants The Company and certain of its subsidiaries (collectively known as the “Borrower”) currently have a Credit Agreement with Wells Fargo Bank, National Association. The Credit Agreement will expire on July 5, 2016. It contains a $30.0 million revolving credit facility (the “Facility”) with an opportunity to increase this to $50.0 million, a term loan (the “Term Loan”) and up to $3.0 million of letters of credit, which reduce the availability of the Facility. At March 29, 2015, the principal amount outstanding under the Facility and the Term Loan was $11.0 million and $3.9 million, respectively, along with approximately $455,000 in letters of credit for real estate locations. The Credit Agreement allows for the termination of the Facility by the Borrower without penalty at any time. We expect to use any borrowings under the Credit Agreement for general working capital purposes as needed. Under the Credit Agreement, the Borrower has granted the Lender a security interest in all current and future personal property of the Borrower. Principal amounts outstanding under the Facility bear interest either at an adjusted Eurodollar rate or “Base Rate” plus an applicable margin. The applicable margin depends on the Company's Adjusted Leverage Ratio at the end of the previous quarter. For the three months ended March 29, 2015 and March 30, 2014, our weighted average interest rate for the Facility was 2.76% and 2.85%, respectively. Unused portions of the Facility are subject to a fee, which was 0.375% of the unused amount at March 29, 2015. An option exercise fee would also apply to increased outstanding amounts between $30.0 and $50.0 million. Principal amounts outstanding under the Term Loan bear interest at the same rate as the Facility. The weighted average interest rate of the Term Loan for the three months ended March 29, 2015 and March 30, 2014 was 2.18% and 2.33%, respectively. The Company is required to make minimum annual amortization payments of 10.0% of the principal balance of the Term Loan. The Facility contains various financial covenants as well as customary affirmative and negative covenants for credit facilities of this type. For more information regarding the details of the various financial covenants and customary affirmative and negative covenants, please read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K for the fiscal year ended December 28, 2014. We were in compliance with all covenants as of March 29, 2015.
