Accounting Policies [Abstract]
BasisOfPresentationSignificantAccountingPoliciesAndPriorPeriodAdjustments [Text Block]	Presentation of Condensed Consolidated Financial Statements During interim periods, we follow the accounting policies set forth in our Annual Report on Form 10-K for the fiscal year ended December 27, 2015 (the "2015 Annual Report on Form 10-K") and apply appropriate interim financial reporting standards for a fair statement of our operating results and financial position in conformity with accounting principles generally accepted in the United States of America, as codified by the Financial Accounting Standards Board ("FASB") in the Accounting Standards Codification ("ASC") (referred to herein as "U.S. GAAP"), as indicated below. Users of financial information produced for interim periods in 2016 are encouraged to read this Quarterly Report on Form 10-Q in conjunction with our consolidated financial statements and notes thereto filed with the Securities and Exchange Commission ("SEC") in our 2015 Annual Report on Form 10-K. Interim financial reporting standards require us to make estimates that are based on assumptions regarding the outcome of future events and circumstances not known at that time, including the use of estimated effective tax rates. Inevitably, some assumptions will not materialize, unanticipated events or circumstances may occur which vary from those estimates and such variations may significantly affect our future results. Additionally, interim results may not be indicative of our results for future interim periods or our annual results. We use a 4-4-5 convention for our fiscal quarters, which are thirteen week periods generally ending on the last Sunday of each calendar quarter. We refer to these thirteen week fiscal periods as “quarters” throughout this report. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the SEC’s requirements for quarterly reports on Form 10-Q and, in our opinion, contain all adjustments, of a normal and recurring nature, which are necessary for a fair statement of (i) the condensed consolidated statements of operations for the thirteen and thirty-nine week periods ended September 25, 2016 and September 27, 2015, (ii) the condensed consolidated statements of comprehensive (loss) income for the thirteen and thirty-nine week periods ended September 25, 2016 and September 27, 2015, (iii) the condensed consolidated balance sheets at September 25, 2016 and December 27, 2015, (iv) the condensed consolidated statements of cash flows for the thirty-nine week periods ended September 25, 2016 and September 27, 2015, and (v) the condensed consolidated statement of shareholders’ equity for the thirty-nine week period ended September 25, 2016. However, the accompanying unaudited condensed consolidated financial statements do not include all information and notes required by U.S. GAAP. The condensed consolidated balance sheet as of December 27, 2015, included in this report, was derived from our 2015 audited financial statements, but does not include all disclosures required by U.S. GAAP. New Accounting Pronouncements In May 2014, the FASB issued an Accounting Standards Update ("ASU') entitled “Revenue from Contracts with Customers.” The ASU requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB approved a one-year deferral of the effective date. Under the standard it is required to be adopted by public business entities in annual periods beginning on or after December 15, 2017. We are evaluating the impact this guidance will have on our financial position and statement of operations. In July 2015, the FASB issued an ASU entitled “Simplifying the Measurement of Inventory.” The ASU replaces the current lower of cost or market test with a lower of cost or net realizable value test when cost is determined on a first-in, first-out or average cost basis. The standard is effective for public entities for annual reporting periods beginning after December 15, 2016, and interim periods therein. It is to be applied prospectively and early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations. In February 2016, the FASB issued an ASU entitled "Leases." The ASU requires an entity to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. The ASU offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, the ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations. In March 2016, the FASB issued an ASU entitled "Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." The objective of the ASU is to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations. In August 2016, the FASB issued an ASU entitled "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." The objective of the ASU is to address the diversity in practice in the presentation of certain cash receipts and cash payments in the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our statement of cash flows.
