	Sep. 29, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for a complete presentation of the financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation have been included in the accompanying financial statements. For further information, refer to the consolidated financial statements and footnotes included in the Company’s 2017 Form 10-K. As described in Note 2, the Company adopted Accounting Standards Updates (“ASU”) 2017-07 at the beginning of the first quarter of 2018. As part of the adoption, the prior period non-service cost components of pension expense have been reclassified to other expense to conform with the new presentation. In addition, as described in Note 15, the Company realigned certain components within its operating segments during the first quarter of 2018. All prior period disclosures have been restated to reflect the new reportable operating segments.
Fiscal Year	Fiscal Year The Company’s fiscal year is the 52 or 53-week period that ends on the Saturday nearest to December 31. Fiscal years 2018 and 2017 both have 52 weeks. The Company reports its quarterly results of operations on the basis of 13-week quarters for each of the first three fiscal quarters and a 13 or 14-week period for the fiscal fourth quarter.
Revenue Recognition	Revenue Recognition Effective December 31, 2017, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, using the modified retrospective method. Under the modified retrospective method, the impact of applying the standard is recognized as a cumulative effect on retained earnings. The adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows as of the adoption date or for the year-to-date ended September 29, 2018. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. For additional information, refer to Note 6.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes the actual product costs, including inbound freight charges and certain outbound freight charges, purchasing, sourcing, inspection and receiving costs. Warehousing costs are included in selling, general and administrative expenses.
Seasonality	Seasonality The Company’s business is subject to seasonal influences that can cause significant differences in revenue, earnings and cash flows from quarter to quarter; however, the differences have followed a consistent pattern in recent years.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
