Debt Disclosure [Text Block]	4. DEBT At October 27, 2012, a subsidiary of the Company maintained unsecured revolving credit facilities with banks aggregating $75 million (the “Credit Facilities”). The Credit Facilities expire through July 8, 2013 and, currently, any borrowings would bear interest at .3% to .9% above LIBOR or, at our election, .5% below the banks’ reference rate. At October 27, 2012, $2.4 million of the Credit Facilities was used for standby letters of credit and $72.6 million was available for borrowings. The Credit Facilities require the subsidiary to maintain certain financial ratios, principally debt to net worth and debt to EBITDA (as defined in the loan agreements), and contain other restrictions, none of which are expected to have a material effect on our operations or financial position. At October 27, 2012, we were in compliance with all loan covenants and approximately $1.2 million of retained earnings was restricted from distribution. On November 23, 2012, the subsidiary amended a credit facility with a bank to increase the amount of available credit from $25 million to $50 million and extend the maturity date to November 22, 2015.
