Condensed Financial Statements [Text Block]	2. Interim Financial Presentation All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements. The results of operations for the three month and nine months ended August 30, 2014 are not necessarily indicative of results for the full fiscal year. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended November 30, 2013. We calculate an anticipated effective tax rate for the year based on our annual estimates of pretax income or loss and use that effective tax rate to record our year-to-date income tax provision. Any change in annual projections of pretax income or loss could have a significant impact on our effective tax rate for the respective quarter. Our effective tax rate for the three and nine months ended August 30, 2014 differs from the federal statutory rate primarily due to the effects of state income taxes, permanent differences resulting from non-deductible expenses, non-taxable life insurance proceeds, and the expiration of the statute of limitations on certain previously unrecognized tax benefits. The benefit arising from the expiration of that statute of limitations on certain previously unrecognized tax benefits was $111 for the three and nine months ended August 30, 2014 and $221 for the three and nine months ended August 31, 2013. During the second quarter of 2014, the state of New York enacted legislation affecting various corporate tax issues, including the usage of state net operating losses. Based on this legislation, prior limitations on our ability to use those net operating losses have been removed. Thus, we have changed our realization assessment for the deferred tax assets associated with those net operating losses and removed the related valuation allowance resulting in a tax benefit of $190 for the nine months ended August 30, 2014. Our federal tax return for the fiscal year ended November 24, 2012 is currently under examination by the Internal Revenue Service.
