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 28, 2014 (the "2014 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 2015 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 2014 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 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 27, 2015 and September 28, 2014, (ii) the condensed consolidated statements of comprehensive (loss) income for the thirteen and thirty-nine week periods ended September 27, 2015 and September 28, 2014, (iii) the condensed consolidated balance sheets at September 27, 2015 and December 28, 2014, (iv) the condensed consolidated statements of cash flows for the thirty-nine week periods ended September 27, 2015 and September 28, 2014, and (v) the condensed consolidated statement of shareholders’ equity for the thirty-nine week period ended September 27, 2015. 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 28, 2014, included in this report, was derived from our 2014 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. For a public entity, the amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. 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 June 2014, the FASB issued an ASU entitled "Compensation - Stock Compensation." The ASU provides guidance on when the terms of an award provide that a performance target could be achieved after the requisite service period. The new guidance becomes effective for annual reporting periods beginning after December 15, 2015, and early adoption is permitted. We are currently evaluating the impact this guidance will have on our financial position and results of operations. In January 2015, the FASB issued an ASU entitled “Income Statement - Extraordinary and Unusual Items.” The ASU requires that an entity simplify Income Statement presentation by eliminating the concept of "Extraordinary Items". The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We are evaluating the impact this guidance will have on our financial position and statement of operations. In February 2015, the FASB issued an ASU entitled “Consolidation.” The ASU includes amendments to the consolidation analysis which are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption, including adoption in interim periods, is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations. In April 2015, the FASB issued an ASU entitled “Interest - Imputation of Interest.” The ASU requires that an entity simplify the presentation of debt issuance costs. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is allowed for all entities for financial statements that have not been previously issued. We are evaluating the impact this guidance will have on our financial position and statement of operations. In April 2015, the FASB issued an ASU entitled “Compensation - Retired Benefits.” The ASU provides practical expedients for the measurement date of an employer's defined benefit obligation and plan assets. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, and early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations. In June 2015, the FASB issued an ASU entitled “Technical Corrections and Improvements.” The ASU provides changes to clarify the ASC, correct unintended application of guidance, and make minor improvements to the ASC. The amendments in this ASU that require transition guidance are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon the issuance of this update. 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.

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 28, 2014 (the "2014 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.
