Basis of Presentation and Summary of Significant Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The Company employs accounting policies that are in accordance with U.S. generally accepted accounting principles and require management to make estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported period. Significant estimates include those related to revenue recognition, valuation of long-lived assets, goodwill and other intangible assets, income taxes, including valuation allowances, and pension plan assumptions. Actual results could differ from those estimates.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Changes to accounting principles generally accepted in the United States of America (U.S. GAAP) are established by the Financial Accounting Standards Board (FASB) in the form of accounting standards updates (ASUs) to the FASB's Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position and results of operations. Leases In February 2016, the FASB issued ASU 2016-02, "Leases", which requires lessees to recognize most leases on-balance sheet, thereby increasing their reported assets and liabilities, in some cases very significantly. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. ASU 2016-02 mandates a modified retrospective transition method for all entities. The Company has made considerable progress in completing its assessment of the impact of this standard. The Company has performed a high level analysis of its current lease portfolio and has established a cross-functional project team to assist in the implementation of this ASU. We have assembled an inventory of our current leases, are developing processes and tools, including lease management software, to implement the new standard, and are identifying and designing changes to internal controls. Based on the current status of this assessment, the adoption of this standard is not expected to have a material impact on the Company's financial statements. Intangibles – Goodwill and Other In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment", which no longer requires an entity to perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, goodwill will be measured using the difference between the carrying amount and the fair value of the reporting unit. The standard is effective for the interim and annual periods beginning on or after December 15, 2019, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company's financial statements. We are currently evaluating the timing of adoption of this standard. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued ASU 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income", which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act. The standard is effective for the interim and annual periods beginning after December 15, 2018, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company's financial statements. Retirement Benefits In August 2018, the FASB issued ASU 2018-14, "Compensation – Retirement Benefits – Defined Benefit Plans – General: Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans," which removes disclosures that no longer are considered cost beneficial, clarifies the specific requirements of certain disclosures and adds disclosure requirements identified as relevant. The standard is effective for annual periods beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the timing of adoption of this standard. The adoption of this standard is not expected to have a material impact on the Company's financial statements. Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement," which eliminates, amends and adds disclosure requirements for fair value measurement. The standard is effective for the interim and annual periods beginning after December 15, 2019, with early adoption permitted. We are currently evaluating the timing of adoption of this standard. The adoption of this standard is not expected to have a material impact on the Company's financial statements. Recently Adopted Accounting Standards On January 1, 2018, the Company adopted the provisions of ASU No. 2014-09, "Revenue from Contracts with Customers". The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The standard also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. The Company has elected to use the cumulative effect transition method and there has not been a change to our previously reported financial results. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. We measure revenue based on the consideration specified in the customer arrangement and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as, the customer receives the benefit of the performance obligation. Customers typically receive the benefit as goods are delivered and services are performed. We utilized a comprehensive approach to assess the impact of the standard on our contract portfolio by reviewing our current accounting policies and practices to identify potential differences that would result from applying the new requirements to our revenue contracts, including evaluation of our performance obligations, principal versus agent considerations and variable consideration. We completed our contract and business process reviews and implemented changes to our controls to support recognition and disclosures under the new standard. We recognize revenue when our performance obligation is satisfied. See Note 2 to the Condensed Consolidated Financial Statements. On January 1, 2018, the Company adopted the provisions of ASU 2017-07, "Compensation – Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost", which requires companies to present the service cost component of the net benefit cost in the same line items in which they report compensation cost. All other components of net periodic benefit cost will be presented outside operating income. The provisions have been applied retrospectively for the income statement presentation requirements. Prior to the adoption of the standard, the Company classified all net periodic benefit costs within operating costs, primarily within "Marketing and administrative expenses" on the Condensed Consolidated Statement of Income. The line item classification changes required by the standard did not impact the Company's pre-tax earnings or net income; however, "Income from operations" and "Other non-operating income (deductions), net" changed by immaterial offsetting amounts. As a result of the accounting change, the Company reclassified approximately $0.4 million and $1.3 million from marketing and administrative expenses to other deductions for the three and nine month periods ended October 1, 2017 to conform to the current year presentation. On January 1, 2018, the Company early adopted the provisions of ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which improves and simplifies existing standard to allow companies to better reflect their risk management activities in the financial statements. The standard expands the ability to hedge nonfinancial and financial risk components, eliminates the requirement to separately measure and recognize hedge ineffectiveness and eases requirements of an entity's assessment of hedge effectiveness. The adoption of this standard did not have an impact on the Company's financial statements. On January 1, 2018, the Company adopted the provisions of ASU 2017-01, "Business Combinations," which 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. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The adoption of this new standard did not have an impact on the Company's financial statements.
