Current Relevant Accounting Standards [Abstract]
Current Relevant Accounting Standards	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606), as amended by several subsequent ASU’s, which establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. In August 2015, the FASB issued a one-year deferral of the effective date of this new guidance resulting in it now being effective for the Company beginning in fiscal year 2018. The Company has evaluated the impact of adoption of the ASU. The Company’s assessment of the new guidance has identified customer loyalty programs and gift cards affected by the new guidance. The Company adopted the new standard using the modified retrospective method beginning December 31, 2017. The effects related to these transactions did not materially effect the Company’s Consolidated Financial Statements. The Company determined that the adoption of the ASU did not have a significant impact on the Company’s point of sale product sales. In January 2016, the FASB issued ASU 2016-01 Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 generally requires that equity investments (excluding equity method investments) be measured at fair value with changes in fair value recognized in net income. The adoption of ASU 2016-01 had an impact on the net income reported in the Company’s Consolidated Statements of Income for the first 13 weeks of 2018 of $0.8 million. The ASU was adopted as of December 31, 2017. The cumulative effect of the adoption was made to the balance sheet as of December 31, 2017 and resulted in a reclassification of $5.5 million of related accumulated unrealized gains, net of applicable deferred income taxes, that were included in accumulated other comprehensive income to retained earnings, resulting in no impact on the Company’s shareholders’ equity. In February 2016, the FASB issued ASU 2016-02 Leases (Topic 842). ASU 2016-02 requires lessees to recognize assets and liabilities for the rights and obligations created by their leases with lease terms more than 12 months. ASU 2016-02 will become effective for annual periods beginning after December 15, 2018 and for interim periods within those fiscal years. The Company is currently in the process of evaluating the impact of adoption of the ASU and expects the adoption to have a significant impact on the Company’s Consolidated Balance Sheets. In March 2016, the FASB issued ASU 2016-04 Liabilities – Extinguishments of Liabilities (Subtopic 405-20) Recognition of Breakage for Certain Prepaid Stored-Value Products. ASU 2016-04 requires that an entity must disclose the methodology and specific judgements made in applying the breakage recognized. ASU 2016-04 will become effective for the financial statements issued for the fiscal years beginning after December 15, 2017. The Company has evaluated the effect of the adoption of the ASU and determined there was not a significant impact on the Company’s Consolidated Financial Statements. The Company adopted ASU 2016-04 beginning December 31, 2017.
