Accounting Policies [Abstract]
Recent Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board ("FASB") issued updated accounting guidance for revenue recognition, which they have subsequently modified. This modified update provides a comprehensive new revenue recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. This guidance will be effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2017. Accordingly, the standard will be effective for the Company on August 26, 2018. The Company has established an implementation team and is working on the completion of its project plan to address the requirements of this standard. The Company is currently reviewing its customer contracts, assessing its incremental costs of obtaining customer contracts, and identifying any potential changes to business processes and controls to support accounting and disclosure considerations under this standard. The Company expects to adopt this standard using the modified retrospective adoption method and continues to evaluate the impact that this guidance will have on its financial statements and related disclosures. In July 2015, the FASB issued updated guidance which changes the measurement principle for inventory from the lower of cost or market to the lower of cost or net realizable value. Subsequent measurement is unchanged for inventory measured using last-in, first-out or the retail inventory method. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016, and is to be applied prospectively, with early adoption permitted. Accordingly, the Company adopted this standard on August 27, 2017. The adoption of this guidance did not have a material impact on its financial statements. In January 2016, the FASB issued updated guidance for the recognition, measurement, presentation, and disclosure of certain financial assets and liabilities. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. Accordingly, the standard will be effective for the Company on August 26, 2018. The Company expects that adoption of this guidance will not have a material impact on its financial statements. In February 2016, the FASB issued updated guidance that improves transparency and comparability among companies by recognizing lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, with early adoption permitted. Accordingly, the standard will be effective for the Company on September 1, 2019. The Company is currently evaluating the impact that this guidance will have on its financial statements and related disclosures. In March 2016, the FASB issued updated guidance that simplifies several aspects of accounting for share-based payment transactions. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016 and, depending on the amendment, must be applied using a prospective transition method, retrospective transition method, modified retrospective transition method, prospectively and/or retroactively, with early adoption permitted. Accordingly, the Company adopted this standard on August 27, 2017. The adoption impact on the consolidated balance sheet as of November 25, 2017 was a cumulative-effect adjustment of $0.7 million, decreasing retained earnings and increasing capital surplus. The impact of the adoption on the consolidated statement of income was a decrease of $1.6 million in income taxes during the thirteen weeks ended November 25, 2017. As a result of the adoption of the updated guidance, our excess tax benefit is no longer included in our calculation of diluted shares under the treasury stock method, resulting in an increase of a nominal amount of shares in the effect of dilutive securities for the thirteen weeks ended November 25, 2017. The election to recognize forfeitures of share-based awards as they occur resulted in an increase of $0.1 million in share-based compensation for the thirteen weeks ended November 25, 2017. Prior periods have not been adjusted. In August 2016, the FASB issued updated guidance that reduces diversity in how certain cash receipts and cash payments are presented and classified in the Consolidated Statements of Cash Flows. This guidance will be effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2017 and will be required to be applied retrospectively, with early adoption permitted. Accordingly, the standard will be effective for the Company on August 26, 2018. The Company is currently evaluating the impact that this guidance will have on its financial statements and related disclosures. In October 2016, the FASB issued updated guidance to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This guidance will be effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2017 and will be required to be applied on a modified retrospective basis, with early adoption permitted. Accordingly, the standard will be effective for the Company on August 26, 2018.
