Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We account for income taxes using the asset and liability method. The asset and liability method requires the recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our assets and liabilities. We calculate current and deferred tax provisions based on estimates and assumptions that could differ from actual results reflected on the income tax returns filed during the following years. Adjustments based on filed returns are recorded when identified in the subsequent years. The effect on deferred taxes of a change in tax rates is recognized in income in the period that the tax rate change is enacted. In assessing the likelihood of realization of deferred tax assets, we consider whether it is more likely than not that some portion of the deferred tax assets will not be realized. A valuation allowance is provided for deferred income taxes when, in our judgment, based upon currently available information and other factors, it is more likely than not that all or a portion of such deferred income tax assets will not be realized. The determination of the need for a valuation allowance is based on an on-going evaluation of current information including, among other things, historical operating results, estimates of future earnings in different taxing jurisdictions and the expected timing of the reversals of temporary differences. We believe that the determination to record a valuation allowance to reduce a deferred income tax asset is a significant accounting estimate because it is based, among other things, on an estimate of future taxable income in the United States and certain other jurisdictions, which is susceptible to change and may or may not occur, and because the impact of adjusting a valuation allowance may be material. Our valuation allowances totaled $3.9 million as of December 28, 2014, and relates to state deferred tax assets for net operating loss and tax credit carryforwards that are not expected to be realized due to changes in tax law, and cessation of business in Kansas. We record uncertain tax positions in accordance with U.S. GAAP on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. If a position does not meet the more likely than not threshold for recognition in step one, no benefit is recorded until the first subsequent period in which the more likely than not standard is met, the issue is resolved with the taxing authority, or the statute of limitations expires. Positions previously recognized are derecognized when we subsequently determine the position no longer is more likely than not to be sustained. Evaluation of tax positions, their technical merits, and measurements using cumulative probability are highly subjective management estimates. Actual results could differ materially from these estimates. Presently, we have not recorded a deferred tax liability for temporary differences related to investments in foreign subsidiaries that are essentially permanent in duration. These temporary differences may become taxable upon a repatriation of earnings from the subsidiaries or a sale or liquidation of the subsidiaries. At this time, the company does not have any plans to repatriate additional income from its foreign subsidiaries. The provision for income taxes for the quarter ended June 28, 2015 was $4.2 million, which resulted in an effective income tax rate of 39 percent. For the six-month period ended June 28, 2015 the provision for income taxes was $3.4 million, which resulted in an effective income tax rate of 24 percent. The effective tax rate for the six-month period ended June 28, 2015 was lower than the statutory rate due to the release of certain liabilities related to uncertain tax positions as a result of the expiration of a statute of limitations, partially offset by non-deductible expenses, state income taxes (net of federal tax benefit) and interest and penalties on unrecognized tax benefits. For the thirteen weeks ended June 29, 2014, the provision for income taxes was $3.6 million, which was an effective income tax rate of 42 percent. For the twenty-six weeks ended June 29, 2014 the provision for income taxes was $6.9 million, which was an effective tax rate of 41 percent. The effective tax rate was unfavorably affected by non-deductible expenses primarily resulting from recent tax law changes in Mexico, state income taxes (net of federal tax benefit) and interest and penalties on unrecognized tax benefits, partially offset by foreign income taxed at rates that are lower than the U. S. statutory rates. We conduct business internationally and, as a result, one or more of our subsidiaries files income tax returns in U.S. federal, U.S. state and certain foreign jurisdictions. Accordingly, in the normal course of business, we are subject to examination by taxing authorities throughout the world, including taxing authorities in Mexico, the Netherlands, India and the United States. We are no longer open for examination by taxing authorities regarding any U.S. federal income tax returns for years before 2012 while the years open for examination under various state and local jurisdictions vary. We expect approximately $1.0 million of unrecognized tax benefits related to our U.S. and Mexico operations will be recognized in the twelve month period ending March 27, 2016 due to the expiration of certain statutes of limitations or due to settlement of uncertain tax positions.
