Debt Disclosure [Abstract]
REVOLVING CREDIT FACILITY	NOTE 4 — REVOLVING CREDIT FACILITY On February 7, 2008, we entered into a Credit Agreement with a bank group (the “Bank Lenders”) providing a $117,500 revolving loan commitment and letter of credit subfacility (the “Credit Facility”). Also on February 7, 2008, we entered into a Loan Agreement with an insurance company (the “Mortgage Lender”) providing us with two term loans, one in the amount of $36,000 (“Tranche A”) and the other in the amount of $9,000 (“Tranche B”), for an aggregate amount of $45,000 (the “Mortgage Facility”). The Credit Facility, as amended, is secured by substantially all our assets other than real property and fixtures. The Mortgage Facility is secured by mortgages on essentially all of our owned real property located in Elgin, Illinois, Gustine, California and Garysburg, North Carolina (the “Encumbered Properties”). The encumbered Elgin, Illinois real property includes almost all of the Old Elgin Site that was purchased prior to our purchase of the land in Elgin, Illinois, on which our Chicago area operations are now consolidated. On July 15, 2011, we entered into a Second Amendment to the Credit Facility (the “Second Amendment”) which extended the maturity date of the Credit Facility from February 7, 2013 to July 15, 2016. In addition, the Second Amendment increases the amount by which we may increase the revolving credit commitment available under the Credit Facility from $15,000 to $22,500. On October 31, 2011, we entered into a Third Amendment to the Credit Facility (the “Third Amendment”). The Third Amendment permits an additional 5% of outstanding accounts receivable from a major customer to be included as eligible in the borrowing base calculation, and the Third Amendment also made technical modifications to definitions. On January 22, 2013, we entered into a Consent and Fourth Amendment to the Credit Facility which permitted us to sell certain intellectual property assets and invest in the capital stock of a company. The portion of the borrowing base calculation based upon machinery and equipment will decrease by $1,500 per year for the first five years to coincide with depreciation of the machinery and equipment collateral. As of June 27, 2013 and June 28, 2012, the weighted average interest rate for the Credit Facility was 2.23% and 2.36%, respectively. The terms of the Credit Facility contain covenants that require us to restrict investments, indebtedness, capital expenditures, acquisitions and certain sales of assets, cash dividends, redemptions of capital stock and prepayment of indebtedness (if such prepayment, among other things, is of a subordinate debt). If loan availability under the Borrowing Base Calculation falls below $25,000, we will be required to maintain a specified fixed charge coverage ratio, tested on a monthly basis. All cash received from customers is required to be applied against the Credit Facility. The Bank Lenders are entitled to require immediate repayment of our obligations under the Credit Facility in the event of default on the payments required under the Credit Facility, a change in control in the ownership of the Company, non-compliance with the financial covenants or upon the occurrence of certain other defaults by us under the Credit Facility (including a default under the Mortgage Facility). As of June 27, 2013, we were in compliance with all covenants under the Credit Facility and we currently expect to be in compliance with the financial covenant in the Credit Facility for the foreseeable future. As of June 27, 2013, we had $81,608 of available credit under the Credit Facility which reflects borrowings of $31,867 and reduced availability as a result of $4,025 in outstanding letters of credit. We would still be in compliance with all restrictive covenants under the Credit Facility if this entire amount were borrowed.
