Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and notes required by United States generally accepted accounting principles (U.S. GAAP) for complete financial statements. In our opinion, the accompanying condensed consolidated financial statements contain all adjustments, which are of a normal and recurring nature, necessary to present fairly the financial position and the results of operations for the interim periods presented. The results of consolidated operations for the three- and six-month periods ended May 31, 2018 are not necessarily indicative of the results to be expected for the full year. Historically, our net sales, net income and cash flow from operations are lower in the first half of the fiscal year and increase in the second half. The typical increase in net sales, net income and cash flow from operations in the second half of the year is largely due to the consumer business cycle in the U.S., where customers typically purchase more products in the fourth quarter due to the Thanksgiving and Christmas holiday seasons. In addition, net income for the six-month period ended May 31, 2018 reflects a significant non-recurring tax benefit as more fully described in note 9. For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended November 30, 2017.
Accounting and disclosure charges	Accounting Pronouncements Adopted in 2018 In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-02 Income Statement-Reporting Comprehensive Income (Topic 220)—Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This guidance 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 enacted in December 2017. The new standard, which would be effective for the first quarter of our fiscal year ending November 30, 2020, permits early adoption in any interim period or fiscal year before the effective date. We adopted this new accounting pronouncement effective December 1, 2017. The adoption resulted in a reclassification of $20.9 million from accumulated other comprehensive income to retained earnings. In July 2015, the FASB issued ASU No. 2015-11 Simplifying the Measurement of Inventory (Topic 330). This guidance is intended to simplify the subsequent measurement of inventories by replacing the current lower of cost or market test with a lower of cost and net realizable value test. We have adopted ASU No. 2015-11 effective December 1, 2017. The adoption of this new accounting pronouncement did not have a material impact on our financial statements. Recently Issued Accounting Pronouncements In August 2017, the FASB issued ASU No. 2017-12 Derivatives and Hedging (Topic 815)—Targeted Improvements to Accounting for Hedging Activities. This guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also modifies the accounting for components excluded from the assessment of hedge effectiveness, eases documentation and assessment requirements and modifies certain disclosure requirements. The new standard will be effective for the first quarter of our fiscal year ending November 30, 2020. Early adoption is permitted in any interim period or fiscal year before the effective date for all entities. If the guidance is early adopted in an interim period, any adjustments would be reflected as of the beginning of the fiscal year that includes that interim period. We have not yet determined our date of adoption or the impact from adoption of this new accounting pronouncement on our financial statements. In March 2017, the FASB issued ASU No. 2017-07 Compensation-Retirement Benefits (Topic 715)—Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This guidance revises how employers that sponsor defined benefit pension and other postretirement plans present the net periodic benefit cost in their income statement and requires that the service cost component of net periodic benefit cost be presented in the same income statement line items as other employee compensation costs from services rendered during the period. Of the components of net periodic benefit cost, only the service cost component will be eligible for asset capitalization. The other components of the net periodic benefit cost must be presented separately from the line items that include the service cost and outside of any subtotal of operating income on the income statement. The new standard will be effective for the first quarter of our fiscal year ending November 30, 2019. We have not yet determined the impact from adoption of this new accounting pronouncement on our financial statements. In January 2017, the FASB issued ASU No. 2017-04 Intangibles—Goodwill and Other Topics (Topic 350)—Simplifying the Test for Goodwill Impairment. This guidance eliminates the requirement to calculate the implied fair value of goodwill of a reporting unit to measure a goodwill impairment charge. Instead, a company will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. The new standard will be effective for the first quarter of our fiscal year ending November 30, 2021. Early adoption is permitted for all entities for annual and interim goodwill impairment testing dates after January 1, 2017. We have not yet determined the impact from adoption of this new accounting pronouncement on our financial statements. In January 2017, the FASB issued ASU No. 2017-01 Business Combinations (Topic 805)—Clarifying the Definition of a Business. This guidance changes the definition of a business to assist entities in evaluating when a set of transferred assets and activities constitutes a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in Accounting Standards Codification (ASC 606) Revenue from Contracts with Customers. The new standard will be effective for the first quarter of our fiscal year ending November 30, 2019. Early adoption is permitted for all entities. We have not yet determined the impact from adoption of this new accounting pronouncement on our financial statements. In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842). This guidance revises existing practice related to accounting for leases under Accounting Standards Codification Topic 840 Leases (ASC 840) for both lessees and lessors. Our leases principally relate to: (i) certain real estate, including that related to a number of administrative, distribution and manufacturing locations, and, beginning in May 2018, to our new headquarters building; (ii) certain machinery and equipment, including a corporate airplane and automobiles; and (iii) certain software. The new guidance in ASU No. 2016-02 requires lessees to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease). The lease liability will be equal to the present value of lease payments and the right-of-use asset will be based on the lease liability, subject to adjustment such as for initial direct costs. For income statement purposes, the new standard retains a dual model similar to ASC 840, requiring leases to be classified as either operating or finance. For lessees, operating leases will result in straight-line expense (similar to current accounting by lessees for operating leases under ASC 840) while finance leases will result in a front-loaded expense pattern (similar to current accounting by lessees for capital leases under ASC 840). The new standard will be effective for the first quarter of our fiscal year ending November 30, 2020. We have not yet determined the impact from adoption of this new accounting pronouncement on our financial statements. In May 2014, the FASB issued ASU No. 2014-09 Revenue from Contracts with Customers (Topic 606). This guidance is intended to improve—and converge with international standards—the financial reporting requirements for revenue from contracts with customers. The new standard will be effective for the first quarter of our fiscal year ending November 30, 2019. In preparation for our adoption of the new standard in our fiscal year ending November 30, 2019, we have obtained representative samples of contracts and other forms of agreements with our customers in the U.S. and international locations and are evaluating the provisions contained therein in light of the five-step model specified by the new guidance. That five-step model includes: (1) determination of whether a contract—an agreement between two or more parties that creates legally enforceable rights and obligations—exists; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when (or as) the performance obligation is satisfied. We are also evaluating the impact of the new standard on certain common practices currently employed by us and by other manufacturers of consumer products, such as slotting fees, co-operative advertising, rebates and other pricing allowances, merchandising funds and consumer coupons. We have not yet determined the impact of the new standard on our financial statements or whether we will adopt on a prospective or retrospective basis in the first quarter of our fiscal year ending November 30, 2019.
