New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”. This update simplifies the subsequent measurement of goodwill by eliminating “Step 2” from the goodwill impairment test. This update is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the effect this standard will have on the Company's consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”. This update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This update is effective for annual and interim reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the effect this standard will have on the Company's consolidated financial statements and related disclosures. In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory”. This update requires the income tax impact of an intra-entity sale or transfer of an asset other than inventory to be recognized when the sale or transfer occurs, rather than when the asset has been sold to an outside party. This update is effective for annual and interim reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the effect this standard will have on the Company's consolidated financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”. This update addresses how certain cash inflows and outflows are classified in the statement of cash flows to eliminate existing diversity in practice. This update is effective for annual and interim reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the effect this standard will have on the Company's consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-09, “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. This update simplifies accounting for 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. The Company adopted ASU 2016-09 during the thirteen weeks ended March 28, 2017 on a prospective basis. Prior periods have not been adjusted. The primary impact of adoption was the recognition of excess tax benefits of $0.3 million as a reduction to the provision for income taxes during the thirteen weeks ended March 28, 2017. Prior to the adoption of ASU 2016-09, this amount would have been recognized as an increase of additional paid-in capital. The adoption of ASU 2016-09 did not have a material impact on the computation of weighted-average diluted shares outstanding during the thirteen weeks ended March 28, 2017. The Company also elected to continue estimating forfeitures when determining the amount of compensation costs to be recognized in each period. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. This update will increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This update is effective for annual and interim reporting periods beginning after December 15, 2018. Early adoption is permitted. Based on a preliminary assessment, the Company expects the standard to have a material impact on its assets and liabilities due to the recognition of right-of-use assets and lease liabilities on its Consolidated Balance Sheets at the beginning of the earliest period presented. The Company is continuing its assessment, which may identify additional impacts this standard will have on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This update provides a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. In August 2015, the FASB issued ASU 2015-14, delaying the effective date for adoption. The update is now effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted. The update permits the use of either the retrospective or cumulative effect transition method. The FASB has also issued the several standards which provide additional clarification and implementation guidance on the previously issued ASU 2014-09 and have the same effective date as the original standard. The Company is currently evaluating the overall impact that ASU 2014-09 will have on the Company's consolidated financial statements, as well as the expected timing and method of adoption. Based on a preliminary assessment, the Company has determined that the adoption will change the timing of recognition of gift card breakage income, which is currently recognized using the remote method. The new guidance will require application of the proportional method. The Company is continuing its assessment, which may identify additional impacts this standard will have on its consolidated financial statements and related disclosures.
