Accounting Policies [Abstract]
Accounting Policies	ACCOUNTING POLICIES Basis of presentation The consolidated financial statements include the accounts of the Kellogg Company, those of the subsidiaries that it controls due to ownership of a majority voting interest (Kellogg or the Company). The Company continually evaluates its involvement with variable interest entities (VIEs) to determine whether it has variable interests and is the primary beneficiary of the VIE. When these criteria are met, the Company is required to consolidate the VIE. The Company’s share of earnings or losses of nonconsolidated affiliates is included in its consolidated operating results using the equity method of accounting when it is able to exercise significant influence over the operating and financial decisions of the affiliate. The Company uses the cost method of accounting if it is not able to exercise significant influence over the operating and financial decisions of the affiliate. Intercompany balances and transactions are eliminated. The Company’s fiscal year normally ends on the Saturday closest to December 31 and as a result, a 53rd week is added approximately every sixth year. The Company’s 2018, 2017 and 2016 fiscal years each contained 52 weeks and ended on December 29, 2018 , December 30, 2017 , and December 31, 2016, respectively. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods reported. Actual results could differ from those estimates. Cash and cash equivalents Highly liquid investments with remaining stated maturities of three months or less when purchased are considered cash equivalents and recorded at cost. Accounts receivable Accounts receivable consists principally of trade receivables, which are recorded at the invoiced amount, net of allowances for doubtful accounts and prompt payment discounts. Trade receivables do not bear interest. The allowance for doubtful accounts represents management’s estimate of the amount of probable credit losses in existing accounts receivable, as determined from a review of past due balances and other specific account data. Account balances are written off against the allowance when management determines the receivable is uncollectible. As of year-end 2018 , the Company did not have off-balance sheet credit exposure related to its customers. As of year-end 2017 , the Company's off-balance sheet credit exposure related to its customers was immaterial. Please refer to Note 2 for information on sales of accounts receivable. Inventories Inventories are valued at the lower of cost or net realizable value. Cost is determined on an average cost basis. Property The Company’s property consists mainly of plants and equipment used for manufacturing activities. These assets are recorded at cost and depreciated over estimated useful lives using straight-line methods for financial reporting and accelerated methods, where permitted, for tax reporting. Major property categories are depreciated over various periods as follows (in years): manufacturing machinery and equipment 15 - 30 ; office equipment 5 ; computer equipment and capitalized software 3 - 7 ; building components 20 ; building structures 10 - 50 . Cost includes interest associated with significant capital projects. Plant and equipment are reviewed for impairment when conditions indicate that the carrying value may not be recoverable. Such conditions include an extended period of idleness or a plan of disposal. Assets to be disposed of at a future date are depreciated over the remaining period of use. Assets to be sold are written down to realizable value at the time the assets are being actively marketed for sale and a sale is expected to occur within one year. There were no assets held for sale at the year-end 2018 . As of year-end 2017 , the carrying value of assets held for sale was immaterial. Goodwill and other intangible assets Goodwill and indefinite-lived intangibles are not amortized, but are tested at least annually for impairment of value and whenever events or changes in circumstances indicate the carrying amount of the asset may be impaired. An intangible asset with a finite life is amortized on a straight-line basis over the estimated useful life, which materially approximates the pattern of economic benefit. For the goodwill impairment test, the fair value of the reporting units are estimated based on market multiples. This approach employs market multiples based on either sales or earnings before interest, taxes, depreciation and amortization for companies that are comparable to the Company’s reporting units. In the event the fair value determined using the market multiple approach is close to carrying value, the Company may supplement the fair value determination using discounted cash flows. The assumptions used for the impairment test are consistent with those utilized by a market participant performing similar valuations for the Company’s reporting units. Similarly, impairment testing of other intangible assets requires a comparison of carrying value to fair value of that particular asset. Fair values of non-goodwill intangible assets are based primarily on projections of future cash flows to be generated from that asset. For instance, cash flows related to a particular trademark would be based on a projected royalty stream attributable to branded product sales, discounted at rates consistent with rates used by market participants. These estimates are made using various inputs including historical data, current and anticipated market conditions, management plans, and market comparables. Accounts payable The Company has agreements with third parties to provide accounts payable tracking systems which facilitate participating suppliers’ ability to monitor and, if elected, sell payment obligations from the Company to designated third-party financial institutions. Participating suppliers may, at their sole discretion, make offers to sell one or more payment obligations of the Company prior to their scheduled due dates at a discounted price to participating financial institutions. The Company’s goal is to capture overall supplier savings, in the form of payment terms or vendor funding, and the agreements facilitate the suppliers’ ability to sell payment obligations, while providing them with greater working capital flexibility. The Company has no economic interest in the sale of these suppliers’ receivables and no direct financial relationship with the financial institutions concerning these services. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to sell amounts under the arrangements. However, the Company’s right to offset balances due from suppliers against payment obligations is restricted by the agreements for those payment obligations that have been sold by suppliers. As of December 29, 2018 , $893 million of the Company’s outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $701 million of those payment obligations to participating financial institutions. As of December 30, 2017 , $850 million of the Company’s outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $674 million of those payment obligations to participating financial institutions. Revenue recognition The Company recognizes sales upon delivery of its products to customers. Revenue, which includes shipping and handling charges billed to the customer, is reported net of applicable discounts, returns, allowances, and various government withholding taxes. Methodologies for determining these provisions are dependent on local customer pricing and promotional practices, which range from contractually fixed percentage price reductions to reimbursement based on actual occurrence or performance. Where applicable, future reimbursements are estimated based on a combination of historical patterns and future expectations regarding specific in-market product performance. The Company recognizes revenue from the sale of food products which are sold to retailers through direct sales forces, broker and distributor arrangements. The Company also recognizes revenue from the license of our trademarks granted to third parties who uses these trademarks on their merchandise and revenue from hauling services provided to third parties within certain markets. Revenue from these licenses and hauling services is not material to the Company. Contract balances recognized in the current period that are not the result of current period performance are not material to the Company. The Company also does not incur costs to obtain or fulfill contracts. Performance obligations The Company recognizes revenue when (or as) performance obligations are satisfied by transferring control of the goods to customers. Control is transferred upon delivery of the goods to the customer. At the time of delivery, the customer is invoiced with payment terms which are commensurate with the customer’s credit profile. Shipping and/or handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. The Company assesses the goods and services promised in its customers’ purchase orders and identifies a performance obligation for each promise to transfer a good or service (or bundle of goods or services) that is distinct. To identify the performance obligations, the Company considers all the goods or services promised, whether explicitly stated or implied based on customary business practices. For a purchase order that has more than one performance obligation, the Company allocates the total consideration to each distinct performance obligation on a relative standalone selling price basis. Significant Judgments The Company offers various forms of trade promotions and the methodologies for determining these provisions are dependent on local customer pricing and promotional practices, which range from contractually fixed percentage price reductions to provisions based on actual occurrence or performance. Where applicable, future provisions are estimated based on a combination of historical patterns and future expectations regarding specific in-market product performance. Our promotional activities are conducted either through the retail trade or directly with consumers and include activities such as in-store displays and events, feature price discounts, consumer coupons, contests and loyalty programs. The costs of these activities are generally recognized at the time the related revenue is recorded, which normally precedes the actual cash expenditure. The recognition of these costs therefore requires management judgment regarding the volume of promotional offers that will be redeemed by either the retail trade or consumer. These estimates are made using various techniques including historical data on performance of similar promotional programs. Differences between estimated expense and actual redemptions are normally immaterial and recognized as a change in management estimate in a subsequent period. Advertising and promotion The Company expenses production costs of advertising the first time the advertising takes place. Advertising expense is classified in selling, general and administrative (SGA) expense. The Company classifies promotional payments to its customers, the cost of consumer coupons, and other cash redemption offers in net sales. Promotional allowances are estimated using various techniques including historical cash expenditure and redemption experience and patterns. Differences between estimated expense and actual redemptions are normally immaterial and recognized as a change in management estimate in a subsequent period. The liability associated with these promotions are recorded in other current liabilities. The cost of promotional package inserts is recorded in cost of goods sold (COGS). Other types of consumer promotional expenditures are recorded in SGA expense. Research and development The costs of research and development (R&D) are expensed as incurred and are classified in SGA expense. R&D includes expenditures for new product and process innovation, as well as significant technological improvements to existing products and processes. The Company’s R&D expenditures primarily consist of internal salaries, wages, consulting, and supplies attributable to time spent on R&D activities. Other costs include depreciation and maintenance of research facilities and equipment, including assets at manufacturing locations that are temporarily engaged in pilot plant activities. Stock-based compensation The Company uses stock-based compensation, including stock options, restricted stock, restricted stock units, and executive performance shares, to provide long-term performance incentives for its global workforce. The Company classifies pre-tax stock compensation expense in SGA and COGS within its corporate operations. Expense attributable to awards of equity instruments is recorded in capital in excess of par value in the Consolidated Balance Sheet. Certain of the Company’s stock-based compensation plans contain provisions that prorate vesting of awards upon retirement, disability, or death of eligible employees and directors. A stock-based award is considered vested for expense attribution purposes when the employee’s retention of the award is no longer contingent on providing subsequent service. Accordingly, the Company recognizes compensation cost immediately for awards granted to retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period. The Company recognizes compensation cost for stock option awards that have a graded vesting schedule on a straight-line basis over the requisite service period for the entire award. Income taxes The Company recognizes uncertain tax positions based on a benefit recognition model. Provided that the tax position is deemed more likely than not of being sustained, the Company recognizes the largest amount of tax benefit that is greater than 50 percent likely of being ultimately realized upon settlement. The tax position is derecognized when it is no longer more likely than not of being sustained. The Company classifies income tax-related interest and penalties as interest expense and SGA expense, respectively, on the Consolidated Statement of Income. The current portion of the Company’s unrecognized tax benefits is presented in the Consolidated Balance Sheet in other current assets and other current liabilities, and the amounts expected to be settled after one year are recorded in other assets and other liabilities. Management monitors the Company’s ability to utilize certain future tax deductions, operating losses and tax credit carryforwards, prior to expiration as well as the reinvestment assertion regarding our undistributed foreign earnings. Changes resulting from management’s assessment will result in impacts to deferred tax assets and the corresponding impacts on the effective income tax rate. Valuation allowances were recorded to reduce deferred tax assets to an amount that will, more likely than not, be realized in the future. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act includes a provision designed to tax currently global intangible low taxed income (GILTI) starting in 2018. Under the provision, a U.S. shareholder is required to include in gross income the amount of its GILTI, which is 50% of the excess of the shareholder’s net tested income of its controlled foreign corporation over the deemed tangible income return. The amount of GILTI included by a U.S. shareholder is computed by aggregating all controlled foreign corporations (CFC). Shareholders are allowed to claim a foreign tax credit for 80 percent of the taxes paid or accrued with respect to the tested income of each CFC, subject to some limitations. The Financial Accounting Standards Board (FASB) staff has indicated that a company should make and disclose a policy election as to whether it will (1) recognize deferred taxes for basis differences expected to reverse as GILTI or (2) account for GILTI as a period cost if and when incurred. During 2018, the Company elected to account for the GILTI as a period cost and has included an estimate for GILTI in its effective tax rate. Derivative Instruments The fair value of derivative instruments is recorded in other current assets, other assets, other current liabilities or other liabilities. Gains and losses representing either hedge ineffectiveness, hedge components excluded from the assessment of effectiveness, or hedges of translational exposure are recorded in the Consolidated Statement of Income in other income (expense), net (OIE) or interest expense. In the Consolidated Statement of Cash Flows, settlements of cash flow and fair value hedges are classified as an operating activity; settlements of all other derivative instruments, including instruments for which hedge accounting has been discontinued, are classified consistent with the nature of the instrument. Cash flow hedges. Qualifying derivatives are accounted for as cash flow hedges when the hedged item is a forecasted transaction. Gains and losses on these instruments are recorded in other comprehensive income until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive income (loss) (AOCI) to the Consolidated Statement of Income on the same line item as the underlying transaction. Fair value hedges. Qualifying derivatives are accounted for as fair value hedges when the hedged item is a recognized asset, liability, or firm commitment. Gains and losses on these instruments are recorded in earnings, offsetting gains and losses on the hedged item. Net investment hedges. Qualifying derivative and nonderivative financial instruments are accounted for as net investment hedges when the hedged item is a nonfunctional currency investment in a subsidiary. Gains and losses on these instruments are included in foreign currency translation adjustments in AOCI. Derivatives not designated for hedge accounting. Gains and losses on these instruments are recorded in the Consolidated Statement of Income, on the same line item as the underlying hedged item. Foreign currency exchange risk. The Company is exposed to fluctuations in foreign currency cash flows related primarily to third-party purchases, intercompany transactions and when applicable, nonfunctional currency denominated third-party debt. The Company is also exposed to fluctuations in the value of foreign currency investments in subsidiaries and cash flows related to repatriation of these investments. Additionally, the Company is exposed to volatility in the translation of foreign currency denominated earnings to U.S. dollars. Management assesses foreign currency risk based on transactional cash flows and translational volatility and may enter into forward contracts, options, and currency swaps to reduce fluctuations in long or short currency positions. Forward contracts and options are generally less than 18 months duration. Currency swap agreements are established in conjunction with the term of underlying debt issues. For foreign currency cash flow and fair value hedges, the assessment of effectiveness is generally based on changes in spot rates. Changes in time value are reported in OIE. Interest rate risk. The Company is exposed to interest rate volatility with regard to future issuances of fixed rate debt and existing and future issuances of variable rate debt. The Company periodically uses interest rate swaps, including forward-starting swaps, to reduce interest rate volatility and funding costs associated with certain debt issues, and to achieve a desired proportion of variable versus fixed rate debt, based on current and projected market conditions. Fixed-to-variable interest rate swaps are accounted for as fair value hedges and the assessment of effectiveness is based on changes in the fair value of the underlying debt, using incremental borrowing rates currently available on loans with similar terms and maturities. Price risk. The Company is exposed to price fluctuations primarily as a result of anticipated purchases of raw and packaging materials, fuel, and energy. The Company has historically used the combination of long-term contracts with suppliers, and exchange-traded futures and option contracts to reduce price fluctuations in a desired percentage of forecasted raw material purchases over a duration of generally less than 18 months. Pension benefits, nonpension postretirement and postemployment benefits The Company sponsors a number of U.S. and foreign plans to provide pension, health care, and other welfare benefits to retired employees, as well as salary continuance, severance, and long-term disability to former or inactive employees. The recognition of benefit expense is based on actuarial assumptions, such as discount rate, long-term rate of compensation increase, and long-term rate of return on plan assets and health care cost trend rate. Service cost is reported in COGS and SGA expense on the Consolidated Statement of Income. All other components of net periodic pension cost are included in OIE. Postemployment benefits. The Company recognizes an obligation for postemployment benefit plans that vest or accumulate with service. Obligations associated with the Company’s postemployment benefit plans, which are unfunded, are included in other current liabilities and other liabilities on the Consolidated Balance Sheet. All gains and losses are recognized over the average remaining service period of active plan participants. Postemployment benefits that do not vest or accumulate with service or benefits to employees in excess of those specified in the respective plans are expensed as incurred. Pension and nonpension postretirement benefits. The Company recognizes actuarial gains and losses in operating results in the year in which they occur. Experience gains and losses are recognized annually as of the measurement date, which is the Company’s fiscal year-end, or when remeasurement is otherwise required under generally accepted accounting principles. The Company uses the fair value of plan assets to calculate the expected return on plan assets. Reportable segments are allocated service cost. All other components of pension and postretirement benefit expense, including interest cost, expected return on assets, prior service cost, and experience gains and losses are considered unallocated corporate costs and are not included in the measure of reportable segment operating results. See Note 18 for more information on reportable segments. Management reviews the Company’s expected long-term rates of return annually; however, the benefit trust investment performance for one particular year does not, by itself, significantly influence this evaluation. The expected rates of return are generally not revised provided these rates fall between the 25th and 75th percentile of expected long-term returns, as determined by the Company’s modeling process. For defined benefit pension and postretirement plans, the Company records the net overfunded or underfunded position as a pension asset or pension liability on the Consolidated Balance Sheet. New accounting standards Income Taxes. In October 2016, the Financial Accounting Standards Board (FASB), as part of their simplification initiative, issued an Accounting Standards Update (ASU) to improve the accounting for income tax consequences of intra-entity transfers of assets other than inventory. Current Generally Accepted Accounting Principles (GAAP) prohibit recognition of current and deferred income taxes for intra-entity asset transfers until the asset has been sold to an outside party, which is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. The amendments in the ASU eliminate the exception, such that entities should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. That is, early adoption should be the first interim period if an entity issues interim financial statements. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the period of adoption. The Company early adopted the ASU in the first quarter of 2017. As a result of intercompany transfers of intellectual property, the Company recorded a $39 million reduction in income tax expense during the year ended December 30, 2017. Upon adoption, there was no cumulative effect adjustment to retained earnings. Simplifying the Measurement of Inventory. In July 2015, the FASB issued an ASU to simplify the measurement of inventory. The ASU requires that inventory be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted the updated standard in the first quarter of 2017 with no material impact to the financial statements, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. In August 2017, the FASB issued an ASU intended to simplify hedge accounting by better aligning an entity’s financial reporting for hedging relationships with its risk management activities. The ASU also simplifies the application of the hedge accounting guidance. The new guidance is effective fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. For cash flow hedges existing at the adoption date, the standard requires adoption on a modified retrospective basis with a cumulative-effect adjustment to the Consolidated Balance Sheet as of the beginning of the year of adoption. The amendments to presentation guidance and disclosure requirements are required to be adopted prospectively. The Company adopted the ASU in the first quarter of 2018. The impact of adoption was immaterial to the financial statements. Improving the Presentation of net Periodic Pension Cost and net Periodic Postretirement Benefit Cost. In March 2017, the FASB issued an ASU to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The amendments in this ASU should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. The Company adopted the ASU in the first quarter of 2018. Refer to Impacts to Previously Reported Results below for the impact of adoption of the standard on our consolidated financial statements. Simplifying the test for goodwill impairment. In January 2017, the FASB issued an ASU to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. The ASU is effective for an entity's annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The amendments in this ASU should be applied on a prospective basis. The Company adopted the ASU in the first quarter of 2018 with no impact. Statement of Cash Flows. In August 2016, the FASB issued an ASU to provide various cash flow statement classification guidance for certain cash receipts and payments of which the following amendments were most applicable to the Company: (a) debt prepayment or extinguishment costs; (b) contingent consideration payments made after a business combination; (c) insurance settlement proceeds; (d) distributions from equity method investees; (e) beneficial interests in securitization transactions and (f) application of the predominance principle for cash receipts and payments with aspects of more than one class of cash flows. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period, in which case adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The amendments in this ASU should be applied retrospectively. The Company adopted the new ASU in the first quarter of 2018. Refer to Impacts to Previously Reported Results below for the impact of adoption of the standard on our consolidated financial statements. Recognition and measurement of financial assets and liabilities. In January 2016, the FASB issued an ASU which requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in net income and which updates certain presentation and disclosure requirements. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption can be elected for all financial statements of fiscal years and interim periods that have not yet been issued or that have not yet been made available for issuance. Entities should apply the update by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The Company adopted the updated standard in the first quarter of 2018. The impact of adoption was immaterial to the financial statements. Revenue from contracts with customers. In May 2014, the FASB issued an ASU, as amended, which provides guidance for accounting for revenue from contracts with customers. The core principle of this ASU is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services. To achieve that core principle, an entity would be required to apply the following five steps: 1) identify the contract(s) with a customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The Company adopted the updated standard in the first quarter of 2018 using the full retrospective method and restated previously reported amounts. In connection with the adoption, the Company made reclassification of certain customer allowances. The adoption effects relate to the timing of recognition and classification of certain promotional allowances. The updated revenue standard also required additional disaggregated revenue disclosures. Refer to Impacts to Previously Reported Results below for the impact of adoption of the standard on our consolidated financial statements. Practical expedients The Company elected the following pra

Transfers and Servicing of Financial Assets [Abstract]
Transfers and Servicing of Financial Assets [Text Block]	SALE OF ACCOUNTS RECEIVABLE During 2016, The Company initiated a program in which a customer could extend their payment terms in exchange for the elimination of early payment discounts (Extended Terms Program). The Company has two Receivable Sales Agreements (Monetization Programs) and previously had a separate U.S. accounts receivable securitization program (Securitization Program), both described below, which are intended to directly offset the impact the Extended Terms Program would have on the days-sales-outstanding (DSO) metric that is critical to the effective management of the Company's accounts receivable balance and overall working capital. The Company terminated the Securitization Program at the end of 2017 and entered into the second monetization program during the quarter ended March 31, 2018. The Monetization and Securitization Programs are designed to effectively offset the impact on working capital of the Extended Terms Program. The Company has no retained interest in the receivables sold, however the Company does have collection and administrative responsibilities for the sold receivables. The Company has not recorded any servicing assets or liabilities as of December 29, 2018 and December 30, 2017 for these agreements as the fair value of these servicing arrangements as well as the fees earned were not material to the financial statements. Monetization Program The Company has two Monetization Programs, for a discrete group of customers, to sell, on a revolving basis, certain trade accounts receivable invoices to third party financial institutions. Transfers under this agreement are accounted for as sales of receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. The Monetization Programs provide for the continuing sale of certain receivables on a revolving basis until terminated by either party; however the maximum receivables that may be sold at any time is $1,033 million . Accounts receivable sold of $900 million and $601 million remained outstanding under these arrangements as of December 29, 2018 and December 30, 2017, respectively. The proceeds from these sales of receivables are included in cash from operating activities in the Consolidated Statement of Cash Flows. The recorded net loss on sale of receivables was $26 million , $11 million and $5 million for the years ended December 29, 2018, December 30, 2017 and December 31, 2016, respectively. The recorded loss is included in Other income and expense. Securitization Program Between July 2016 and December 2017, the Company had a Securitization Program with a third party financial institution. Under the program, the Company received cash consideration of up to $600 million and a deferred purchase price asset for the remainder of the purchase price. Transfers under the Securitization Program were accounted for as sales of receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. This Securitization Program utilized Kellogg Funding Company (Kellogg Funding), a wholly-owned subsidiary of the Company. Kellogg Funding's sole business consisted of the purchase of receivables, from its parent or other subsidiary and subsequent transfer of such receivables and related assets to financial institutions. Although Kellogg Funding is included in the Company's consolidated financial statements, it is a separate legal entity with separate creditors who will be entitled, upon its liquidation, to be satisfied out of Kellogg Funding assets prior to any assets or value in Kellogg Funding becoming available to the Company or its subsidiaries. The assets of Kellogg Funding are not available to pay creditors of the Company or its subsidiaries. The Securitization Program was structured to expire in July 2018, but was terminated at the end of 2017. In March 2018 the Company substantially replaced the securitization program with the second monetization program. Kellogg Funding had no creditors and held no assets at December 29, 2018. As of December 30, 2017, approximately $433 million of accounts receivable sold to Kellogg Funding under the Securitization Program remained outstanding, for which the Company received net cash proceeds of approximately $412 million and a deferred purchase price asset of approximately $21 million . The portion of the purchase price for the receivables which is not paid in cash by the financial institutions is a deferred purchase price asset, which is paid to Kellogg Funding as payments on the receivables are collected from customers. The deferred purchase price asset represents a beneficial interest in the transferred financial assets and is recognized at fair value as part of the sale transaction. The deferred purchase price asset is included in Other current assets on the Consolidated Balance Sheet as of December 30, 2017. Upon final settlement of the program in March 2018, the outstanding deferred purchase price asset of $21 million was exchanged for previously sold trade accounts receivable. The recorded net loss on sale of receivables is approximately $7 million for the year ended December 30, 2017 and is not material for year ended December 31, 2016. The recorded net loss on sale of receivables is included in Other income and expense. Other programs Additionally, from time to time certain of the Company's foreign subsidiaries will transfer, without recourse, accounts receivable balances of certain customers to financial institutions. These transactions are accounted for as sales of the receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. Accounts receivable sold of $93 million and $86 million remained outstanding under these programs as of December 29, 2018 and December 30, 2017, respectively. The proceeds from these sales of receivables are included in cash from operating activities in the Consolidated Statement of Cash Flows. The recorded net loss on the sale of these receivables is included in Other income and expense and is not material.

Acquisitions, Goodwill and Other Intangibles [Abstract]
Acquisitions, West Africa Investments, Goodwill and Other Intangible Assets [Text Block]	ACQUISITIONS, WEST AFRICA INVESTMENTS, GOODWILL AND OTHER INTANGIBLE ASSETS Multipro acquisition On May 2, 2018, the Company (i) acquired an incremental 1% ownership interest in Multipro, a leading distributor of a variety of food products in Nigeria and Ghana, and (ii) exercised its call option (Purchase Option) to acquire a 50% interest in Tolaram Africa Foods, PTE LTD (TAF), a holding company with a 49% equity interest in an affiliated food manufacturer, resulting in the Company having a 24.5% interest in the affiliated food manufacturer. The aggregate cash consideration paid was approximately $419 million and was funded through cash on hand and short-term borrowings, which was refinanced with long-term borrowings in May 2018. As part of the consideration for the acquisition, an escrow established in connection with the original Multipro investment in 2015, which represented a significant portion of the amount paid for the Company’s initial investment, was released by the Company. The amount paid to exercise the Purchase Option was subject to certain working capital and net debt adjustments based on the actual working capital and net debt existing on the exercise date compared to targeted amounts. These adjustments were finalized during 2018 and resulted in an increase in the purchase price of $1 million . As a result of the Company’s incremental ownership interest in Multipro and concurrent changes to the shareholders' agreement, the Company now has a 51% controlling interest in and began consolidating Multipro. Accordingly, the acquisition was accounted for as a business combination and the assets and liabilities of Multipro were included in the December 29, 2018 Consolidated Balance Sheet and the results of its operations have been included in the Consolidated Statement of Income subsequent to the acquisition date. The aggregate of the consideration paid and the fair value of previously held equity interest totaled $626 million , or $617 million net of cash acquired. The Multipro investment was previously accounted for under the equity method of accounting and the Company recorded our share of equity income or loss from Multipro within Earnings (loss) from unconsolidated entities. In connection with the business combination, the Company recognized a one-time, non-cash gain on the disposition of our previously held equity interest in Multipro of $245 million , which is included within Earnings (loss) from unconsolidated entities. We utilized estimated fair values at the acquisition date to allocate the total consideration exchanged to the net tangible and intangible assets acquired and liabilities assumed. The acquisition resulted in $616 million of non-tax deductible goodwill relating principally to planned growth in new markets, deferred taxes associated with intangible assets, and any intangible assets that did not qualify for separate recognition. We used the excess earnings method, a variation of the income approach, to value a perpetual distribution agreement indefinite lived intangible asset. We also valued customer relationships, using either the excess earnings method or with-and-without method, which is also a variation of the income approach. Some of the more significant assumptions inherent in developing the valuations included the estimated annual net cash flows for each indefinite-lived or definite-lived intangible asset (including net sales, cost of products sold, selling and marketing costs, and working capital/contributory asset charges), the discount rate that appropriately reflects the risk inherent in each future cash flow stream, the assessment of each asset’s life cycle, and competitive trends, as well as other factors. We determined the assumptions used in the financial forecasts using historical data, supplemented by current and anticipated market conditions, estimated product category growth rates, management plans, and market comparables. We used carrying values as of the acquisition date to value certain current and non-current assets and liabilities, as we determined that they represented the fair value of those items at the acquisition date. Deferred income tax assets and liabilities as of the acquisition date represented the expected future tax consequences of temporary differences between the fair values of the assets acquired and liabilities assumed and their tax bases. We estimated the fair value of non-controlling interests assumed consistent with the manner in which we valued all of the underlying assets and liabilities. The assets and liabilities are included in the Consolidated Balance Sheet as of December 29, 2018 within the Asia-Pacific reporting segment. The fair value of the acquired assets, assumed liabilities, and noncontrolling interest include the following: (millions) May 2, 2018 Current assets $ 118 Property 41 Goodwill 616 Intangible assets subject to amortization, primarily customer relationships 425 Intangible assets not subject to amortization, primarily distribution rights 373 Deferred tax liability (254 ) Other liabilities (150 ) Noncontrolling interest (552 ) $ 617 The amounts in the above table represent the final allocation of purchase price as of December 29, 2018. During 2018, deferred tax liabilities were decreased by $2 million and other liabilities were increased by $2 million in conjunction with an updated allocation of the purchase price. Multipro contributed net sales of $536 million and net earnings of $8 million since the acquisition, including transaction fees and integration costs. The Company's consolidated unaudited pro forma historical net sales and net income, as if Multipro had been acquired at the beginning of 2017, exclusive of the non-cash $245 million gain on the disposition of the equity interest recognized in the second quarter of 2018, are estimated as follows: Year-to-date period ended (millions) December 29, 2018 December 30, 2017 Net sales $ 13,829 $ 13,511 Net Income attributable to Kellogg Company $ 1,336 $ 1,255 Investment in TAF The investment in TAF, our interest in an affiliated food manufacturer, is accounted for under the equity method of accounting with the Company’s share of equity income or loss being recognized within Earnings (loss) from unconsolidated entities. The $458 million aggregate of the consideration paid upon exercise and the historical cost value of the Put Option was compared to the estimated fair value of the Company’s ownership percentage of TAF and the Company recognized a one-time, non-cash loss of $45 million within Earnings (loss) from unconsolidated entities, which represents an other than temporary excess of cost over fair value of the investment. The difference between the carrying amount of TAF and the underlying equity in net assets is primarily attributable to brand and customer list intangible assets, a portion of which is being amortized over future periods, and goodwill. RX acquisition In October 2017, the Company completed its acquisition of Chicago Bar Co., LLC, the manufacturer of RXBAR, for $600 million , or $596 million net of cash and cash equivalents. The purchase price was subject to certain working capital and net debt adjustments based on the actual working capital and net debt existing on the acquisition date compared to targeted amounts. These adjustments were finalized during 2018 and resulted in a purchase price reduction of $1 million . The acquisition was accounted for under the purchase price method and was financed with short-term borrowings. For the post-acquisition period ended December 30, 2017, the acquisition added $27 million in net sales and less than $1 million of operating profit in the Company's North America Other reporting segment. The pro forma effects of this acquisition were not material. The assets and liabilities are included in the Consolidated Balance Sheet as of December 29, 2018 within the North America Other reporting segment. The acquired assets and assumed liabilities include the following: (millions) October 27, 2017 Current assets $ 42 Goodwill 373 Intangible assets, primarily indefinite-lived brands 203 Current liabilities (23 ) $ 595 The amounts in the above table represent the final allocation of purchase price as of December 29, 2018, which resulted in a $2 million increase in amortizable intangible assets with a corresponding reduction of goodwill during 2018. Parati acquisition In December 2016, the Company acquired Ritmo Investimentos, controlling shareholder of Parati S/A, Afical Ltda and Padua Ltda ("Parati Group"), a leading Brazilian food group for approximately BRL1.38 billion ( $381 million ) or $379 million , net of cash and cash equivalents. The purchase price was subject to certain working capital and net debt adjustments based on the actual working capital and net debt existing on the acquisition date compared to targeted amounts. These adjustments were finalized during 2017 and resulted in a purchase price reduction of BRL14 million ( $4 million ). The acquisition was accounted for under the purchase price method and was financed with cash on hand and short-term borrowings. For the post-acquisition period ended December 31, 2016, the impacts to net sales and operating profit were not material. The pro forma effects of this acquisition were not material. The assets and liabilities of the Parati Group are included in the Consolidated Balance Sheet as of December 30, 2017 within the Latin America segment. The acquired assets and assumed liabilities include the following: (millions) December 1, 2016 Current assets $ 44 Property 72 Goodwill 165 Intangible assets 148 Current liabilities (48 ) Non-current deferred tax liability and other (6 ) $ 375 During the year ended December 30, 2017, the value of intangible assets subject to amortization increased $39 million , resulting in an immaterial change to amortization expense, and intangible assets not subject to amortization decreased $11 million with an offsetting $28 million adjustment to goodwill in conjunction with an updated allocation of the purchase price. The Company also recognized $7 million for certain pre-acquisition contingencies which increased goodwill during 2017 and are considered to be probable of being incurred as of December 29, 2018 and December 30, 2017. A portion of the acquisition price aggregating $67 million was placed in escrow in favor of the seller for general representations and warranties, as well as pending resolution of specified contingencies arising from the business prior to the acquisition. As of December 29, 2018, approximately $17 million remained in escrow related to specified contingencies, of which approximately $4 million and $1 million is scheduled to be released in 2019 and 2020, respectively. The remaining balance will be released only upon resolution of the related contingency. During 2017, the Company finalized plans to merge the acquired and pre-existing Brazilian legal entities, which resulted in tax basis of the acquired intangible assets. Accordingly, deferred tax liabilities and goodwill were both reduced by $58 million . The amounts in the above table represent the allocation of purchase price as of December 30, 2017 and represent the finalization of the valuations for intangible assets and the Company's evaluation of pre-acquisition contingencies and finalization of the merger. Other acquisitions In September 2016, the Company acquired a majority ownership interest in a natural, bio-organic certified breakfast company for €3 million , which was accounted for under the purchase method and financed with cash on hand. The assets, which primarily consist of indefinite lived intangible assets and goodwill, and liabilities, including non-controlling interests, are included in the Consolidated Balance Sheet as of December 30, 2017 and December 29, 2018 within the Europe segment. In March 2016, the Company completed the acquisition of an organic and natural snack company for $18 million , which was accounted for under the purchase method and financed with cash on hand. The assets, which primarily consist of indefinite lived brands, and liabilities are included in the Consolidated Balance Sheet as of December 30, 2017 and December 29, 2018 within the North America Other segment.

Within this total, approximately $2.8 billion of non-goodwill intangible assets were classified as indefinite-lived, comprised principally of Keebler and Pringles trademarks. The majority of these intangible assets are recorded in our U.S. Snacks reporting unit. The Company currently believes the fair value of goodwill and other intangible assets exceeds their carrying value and that those intangibles so classified will contribute indefinitely to cash flows. The percentage of excess fair value over carrying value of the U.S. Snacks reporting unit was approximately 62% and 57% in 2018 and 2017, respectively. Additionally, the Company has $207 million of goodwill related to the Kashi reporting unit, which was primarily a result of establishing Kashi as a separate operating segment in 2015, which required an allocation of goodwill from our U.S. Snacks operating segment. The 2018 fair value of the Kashi reporting unit was estimated primarily based on a multiple of net sales and discounted cash flows. The percentage of excess over fair value was approximately 12% and 9% , in 2018 and 2017, respectively, using the same methodology on a year-on-year basis. The Company also has $616 million and $798 million of goodwill and other intangible assets, respectively, related to our Multipro operating segment as a result of the acquisition of this business in May 2018. Consistent with expectations given the recent acquisition, the 2018 fair value approximates carrying value for both goodwill and the indefinitely lived assets.

Investments in unconsolidated entities [Text Block]	INVESTMENTS IN UNCONSOLIDATED ENTITIES On May 2, 2018, the Company (i) acquired an incremental 1% ownership interest in Multipro, a leading distributor of a variety of food products in Nigeria and Ghana, and (ii) exercised its call option (Purchase Option) to acquire a 50% interest in Tolaram Africa Foods, PTE LTD (TAF), a holding company with a 49% equity interest in an affiliated food manufacturer, resulting in the Company having a 24.5% interest in the affiliated food manufacturer. As a result of the Company's incremental ownership interest in Multipro and concurrent changes to the shareholders' agreement, the Company now has a 51% controlling interest in and began consolidating Multipro. Accordingly, the acquisition was accounted for as a business combination and the assets and liabilities of Multipro were included in the June 30, 2018 Consolidated Balance Sheet and the results of its operations have been included in the Consolidated Statement of Income subsequent to the acquisition date. TAF and other unconsolidated entities of the Company are suppliers of Multipro. The related trade payables are generally settled on a monthly basis. TAF’s net sales consist of inventory purchases by Multipro. Multipro’s cost of goods sold primarily consists of inventory purchases from TAF and other unconsolidated entities of the Company. See discussion regarding the Multipro acquisition and Investment in TAF , in Note 3. Summarized combined financial information for the Company’s investments in unconsolidated entities is as follows (on a 100% basis, excluding amortization and before the elimination of intercompany accounts): Statement of Operations (millions) 2018 2017 2016 Net sales (a): TAF $ 350 $ — $ — Multipro 281 754 662 Others 81 55 46 Total net sales $ 712 $ 809 $ 708 Gross profit (a): TAF $ 70 $ — $ — Multipro 30 86 71 Others 12 14 10 Total gross profit $ 112 $ 100 $ 81 Income before income taxes (a) 16 43 28 Net income (a) 9 25 15 Balance sheets December 29, 2018 December 30, Current assets $ 312 $ 155 Non-current assets 213 139 Current liabilities (233 ) (181 ) Non-current liabilities (167 ) (37 ) (a) 2018 includes four months of results for Multipro and seven months of results for TAF.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities	RESTRUCTURING AND COST REDUCTION ACTIVITIES The Company views its restructuring and cost reduction activities as part of its operating principles to provide greater visibility in achieving its long-term profit growth targets. Initiatives undertaken are currently expected to recover cash implementation costs within a 3 to 5 -year period of completion. Upon completion (or as each major stage is completed in the case of multi-year programs), the project begins to deliver cash savings and/or reduced depreciation. Total projects The Company recorded $143 million of costs in 2018 associated with cost reduction initiatives. The charges were comprised of $99 million being recorded in Cost of Goods Sold (COGS), $74 million recorded in Selling, General, Administrative (SG&A) expense and $(30) million recorded in Other (Income) Expense, net (OIE). The Company recorded $263 million of costs in 2017 associated with all cost reduction initiatives. The charges were comprised of $115 million expense being recorded in COGS, a $296 million expense recorded in SGA expense, and a $(148) million gain recorded in OIE. During 2016, the Company recorded $325 million of charges associated with all cost reduction initiatives. The charges were comprised of $172 million expense being recorded in COGS, a $152 million expense recorded in SGA expense, and a $1 million loss recorded in OIE. Project K Project K is expected to continue generating a significant amount of savings that may be invested in key strategic areas of focus for the business or utilized to achieve our growth initiatives. Since inception, Project K has reduced the Company’s cost structure, and is expected to provide enduring benefits, including an optimized supply chain infrastructure, an efficient global business services model, a global focus on categories, increased agility from a more efficient organization design, and improved effectiveness in go-to-market models. These benefits are intended to strengthen existing businesses in core markets, increase growth in developing and emerging markets, and drive an increased level of value-added innovation. As of the end of 2018, the Company has approved all remaining Project K initiatives and implementation of these remaining initiatives will be completed in 2019. Project charges, after-tax cash costs and annual savings remain in line with expectations. The Company currently anticipates that the program will result in total pre-tax charges, once all phases are implemented, of approximately $1.6 billion , with after-tax cash costs, including incremental capital expenditures, estimated to be approximately $1.2 billion . Based on current estimates and actual charges incurred to date, the Company expects the total project charges will consist of asset-related costs of approximately $500 million which consists primarily of asset impairments, accelerated depreciation and other exit-related costs; employee-related costs of approximately $400 million which includes severance, pension and other termination benefits; and other costs of approximately $700 million which consists primarily of charges related to the design and implementation of global business capabilities and a more efficient go-to-market model. The Company currently expects that total pre-tax charges related to Project K will impact reportable segments as follows: U.S. Morning Foods (approximately 17% ), U.S. Snacks (approximately 31% ), U.S. Specialty Channels (approximately 1% ), North America Other (approximately 16% ), Europe (approximately 22% ), Latin America (approximately 3% ), Asia-Pacific (approximately 6% ), and Corporate (approximately 4% ). Since inception of Project K, the Company has recognized charges of $1,520 million that have been attributed to the program. The charges were comprised of $6 million being recorded as a reduction of revenue, $893 million being recorded in COGS, $788 million recorded in SGA and $(167) million recorded in OIE. Other projects The Company implemented a global zero-based budgeting (ZBB) program that has delivered annual savings. The Company completed implementation of the ZBB program in 2017. Final project charges, after-tax cash costs and annual savings remain in line with expectations. In support of the ZBB initiative, the Company incurred pre-tax charges of approximately $3 million and $25 million for the years ended December 30, 2017 and December 31, 2016, respectively. Total charges of $40 million were recognized related to implementation of the ZBB program. The tables below provide the details for the charges incurred during 2018, 2017 and 2016 and program costs to date for all programs currently active as of December 29, 2018.

Pension curtailment (gain) loss consists of curtailment gains or losses that resulted from project initiatives. Asset impairments were recorded for fixed assets that were determined to be impaired and were written down to their estimated fair value. See Note 14 for more information. Asset related costs consist primarily of accelerated depreciation. Other costs incurred consist primarily of lease termination costs as well as third-party incremental costs related to the development and implementation of global business capabilities and a more efficient go-to-market model. At December 29, 2018 total project reserves were $104 million , related to severance payments and other costs of which a substantial portion will be paid in 2019.

Equity [Abstract]
Equity	EQUITY Earnings per share Basic earnings per share is determined by dividing net income attributable to Kellogg Company by the weighted average number of common shares outstanding during the period. Diluted earnings per share is similarly determined, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all dilutive potential common shares had been issued. Dilutive potential common shares consist principally of employee stock options issued by the Company, restricted stock units, and to a lesser extent, certain contingently issuable performance shares. Basic earnings per share is reconciled to diluted earnings per share in the following table: (millions, except per share data) Net income attributable to Kellogg Company Average shares outstanding Earnings per share 2018 Basic $ 1,336 347 $ 3.85 Dilutive potential common shares 1 (0.02 ) Diluted $ 1,336 348 $ 3.83 2017 Basic $ 1,254 348 $ 3.61 Dilutive potential common shares 2 (0.03 ) Diluted $ 1,254 350 $ 3.58 2016 Basic $ 699 350 $ 1.99 Dilutive potential common shares 4 (0.02 ) Diluted $ 699 354 $ 1.97 The total number of anti-dilutive potential common shares excluded from the reconciliation for each period was (shares in millions): 2018 - 6.5 ; 2017 - 4.9 ; 2016- 2.8 . Stock transactions The Company issues shares to employees and directors under various equity-based compensation and stock purchase programs, as further discussed in Note 9 . The number of shares issued during the periods presented was (shares in millions): 2018 – 8 ; 2017 – 7 ; 2016– 7 . The Company issued shares totaling less than one million in each of the years presented under Kellogg Direct ™ , a direct stock purchase and dividend reinvestment plan for U.S. shareholders. In December 2017, the board of directors approved a new authorization to repurchase up to $1.5 billion of the Company's common stock beginning in 2018 through December 2019. During 2018 , the Company repurchased 5 million shares of common stock for a total of $320 million . During 2017 , the Company repurchased 7 million shares of common stock for a total of $516 million . During 2016, the Company repurchased 6 million shares of common stock at a total cost of $426 million . Comprehensive income Comprehensive income includes net income and all other changes in equity during a period except those resulting from investments by or distributions to shareholders. Other comprehensive income for all years presented consists of foreign currency translation adjustments, fair value adjustments associated with cash flow hedges and adjustments for net experience gains (losses) and prior service credit (cost) related to employee benefit plans. For the years ended December 30, 2017 and December 31, 2016, the Company modified assumptions for a U.S. postemployment benefit plan. As a result of the U.S. postemployment benefit plan assumption change, a net experience gain was recognized in other comprehensive income with an offsetting reduction in the accumulated postemployment benefit obligation.

The Company has provided various standard indemnifications in agreements to sell and purchase business assets and lease facilities over the past several years, related primarily to pre-existing tax, environmental, and employee benefit obligations. Certain of these indemnifications are limited by agreement in either amount and/or term and others are unlimited. The Company has also provided various “hold harmless” provisions within certain service type agreements. Because the Company is not currently aware of any actual exposures associated with these indemnifications, management is unable to estimate the maximum potential future payments to be made. At December 29, 2018, the Company had not recorded any liability related to these indemnifications.

The effective interest rate on the Debentures, reflecting issuance discount and hedge settlement, was 4.59% . (b) In March 2001, the Company issued long-term debt instruments, primarily to finance the acquisition of Keebler Foods Company, of which $625 million of thirty -year 7.45% Debentures remain outstanding. The effective interest rate on the Debentures, reflecting issuance discount and hedge settlement, was 7.55% . The Debentures contain standard events of default and covenants, and can be redeemed in whole or in part by the Company at any time at prices determined under a formula (but not less than 100% of the principal amount plus unpaid interest to the redemption date). In March 2016, the Company redeemed $475 million of the Debentures. In connection with the debt redemption, the Company incurred $153 million of interest expense, consisting primarily of a premium on the tender offer and also including accelerated losses on pre-issuance interest rate hedges, acceleration of fees and debt discount on the redeemed debt and fees related to the tender offer. (c) In May 2018, the Company issued $600 million of ten -year 4.30% Senior Notes due 2028, using the net proceeds for general corporate purposes, which included repayment of the Company's $400 million , seven -year 3.25% U.S. Dollar Notes due 2018 at maturity, and the repayment of a portion of the Company's commercial paper borrowings used to finance the acquisition of ownership interests in TAF and Multipro. The effective interest rate on the Debentures, reflecting issuance discount and hedge settlement, was 4.34% . (d) In November 2017, the Company issued $600 million of ten -year 3.40% U.S. Dollar Notes, using the net proceeds for general corporate purposes, which included repayment of a portion of the Company's commercial paper borrowings used to finance the acquisition of Chicago Bar Company LLC, the maker of RXBAR. The effective interest rate on the Debentures, reflecting issuance discount and hedge settlement, was 3.49% . (e) In March 2016, the Company issued $750 million of ten -year 3.25% U.S. Dollar Notes, using the net proceeds for general corporate purposes, which included repayment of a portion of the Company's 7.45% U.S. Dollar Debentures due 2031 and a portion of its commercial paper borrowings. The effective interest rate on these Notes, reflecting issuance discount, hedge settlement and interest rate swaps was 4.00% at December 29, 2018 . In September 2016, the Company entered into interest rate swaps with notional amounts totaling $300 million , which effectively converted a portion of these Notes from a fixed rate to a floating rate obligation. These derivative instruments were designated as fair value hedges of the debt obligation. In October 2018, the Company entered into interest rate swaps with notional amounts totaling $450 million , which effectively converted a portion of these Notes from a fixed rate to a floating rate obligation. These derivative instruments were designated as fair value hedges of the debt obligation.

All of the Company’s Notes contain customary covenants that limit the ability of the Company and its restricted subsidiaries (as defined) to incur certain liens or enter into certain sale and lease-back transactions and also contain a change of control provision. The Company and two of its subsidiaries (the Issuers) maintain a program under which the Issuers may issue euro-commercial paper notes up to a maximum aggregate amount outstanding at any time of $750 million or its equivalent in alternative currencies. The notes may have maturities ranging up to 364 days and will be senior unsecured obligations of the applicable Issuer. Notes issued by subsidiary Issuers will be guaranteed by the Company. The notes may be issued at a discount or may bear fixed or floating rate interest or a coupon calculated by reference to an index or formula. There were no commercial paper notes outstanding under this program as of December 29, 2018 and $96 million outstanding under this program as of December 30, 2017 . At December 29, 2018 , the Company had $2.8 billion of short-term lines of credit, virtually all of which were unused and available for borrowing on an unsecured basis. These lines were comprised principally of an unsecured Five-Year Credit Agreement, which the Company entered into in January 2018 and expires in 2023, replacing the Company’s unsecured Five-year Credit Agreement, which would have expired in February 2019. The Five-Year Credit Agreement allows the Company to borrow, on a revolving credit basis, up to $1.5 billion , which includes the ability to obtain letters of credit in an aggregate stated amount up to $75 million and to obtain European swingline loans in an aggregate principal amount up to the equivalent of $300 million . The agreement contains customary covenants and warranties, including specified restrictions on indebtedness, liens and a specified interest coverage ratio. If an event of default occurs, then, to the extent permitted, the administrative agent may terminate the commitments under the credit facility, accelerate any outstanding loans under the agreement, and demand the deposit of cash collateral equal to the lender’s letter of credit exposure plus interest. The Company was in compliance with all covenants as of December 29, 2018 . In January 2019, the Company entered into an unsecured 364-Day Credit Agreement to borrow, on a revolving credit basis, up to $1.0 billion at any time outstanding, to replace the $1.0 billion 364-day facility that expired in January 2019. The new credit facilities contains customary covenants and warranties, including specified restrictions on indebtedness, liens and a specified interest expense coverage ratio. If an event of default occurs, then, to the extent permitted, the administrative agent may terminate the commitments under the credit facility, accelerate any outstanding loans under the agreement, and demand the deposit of cash collateral equal to the lender's letter of credit exposure plus interest. There are no borrowings outstanding under the new credit facilities. Scheduled principal repayments on long-term debt are (in millions): 2019 – $507 ; 2020 – $851 ; 2021 – $973 ; 2022 – $1,045 ; 2023 – $811 ; 2024 and beyond– $4,598 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Compensation [Text Block]	STOCK COMPENSATION The Company uses various equity-based compensation programs to provide long-term performance incentives for its global workforce. Currently, these incentives consist principally of stock options, restricted stock units and, to a lesser extent, executive performance shares. The Company also sponsors a discounted stock purchase plan in the United States and matching-grant programs in several international locations. Additionally, the Company awards restricted stock to its outside directors. These awards are administered through several plans, as described within this Note. The 2017 Long-Term Incentive Plan (2017 Plan), approved by shareholders in 2017, permits awards to employees and officers in the form of incentive and non-qualified stock options, performance units, restricted stock or restricted stock units, and stock appreciation rights. The 2017 Plan, which replaced the 2013 Long-Term Incentive Plan (2013 Plan), authorizes the issuance of a total of (a) 16 million shares; plus (b) the total number of shares remaining available for future grants under the 2013 Plan. The total number of shares remaining available for issuance under the 2017 Plan will be reduced by two shares for each share issued pursuant to an award under the 2017 Plan other than a stock option or stock appreciation right, or potentially issuable pursuant to an outstanding award other than a stock option or stock appreciation right, which will in each case reduce the total number of shares remaining by one share for each share issued. The 2017 Plan includes several limitations on awards or payments to individual participants. Options granted under the 2017 and 2013 Plans generally vest over three years. At December 29, 2018, there were 20 million remaining authorized, but unissued, shares under the 2017 Plan. The Non-Employee Director Stock Plan (2009 Director Plan) was approved by shareholders in 2009 and allows each eligible non-employee director to receive shares of the Company’s common stock annually. The number of shares granted pursuant to each annual award will be determined by the Nominating and Governance Committee of the Board of Directors. The 2009 Director Plan, which replaced the 2000 Non-Employee Director Stock Plan (2000 Director Plan), reserves 500,000 shares for issuance, plus the total number of shares as to which awards granted under the 2009 Director Plan or the 2000 Director Plans expire or are forfeited, terminated or settled in cash. Under both the 2009 and 2000 Director Plans, shares (other than stock options) are placed in the Kellogg Company Grantor Trust for Non-Employee Directors (the Grantor Trust). Under the terms of the Grantor Trust, shares are available to a director only upon termination of service on the Board. Under the 2009 Director Plan, awards were as follows (number of shares): 2018- 30,045 ; 2017- 25,209 ; 2016- 24,249 . The 2002 Employee Stock Purchase Plan was approved by shareholders in 2002 and permits eligible employees to purchase Company stock at a discounted price. This plan allows for a maximum of 2.5 million shares of Company stock to be issued at a purchase price equal to 95% of the fair market value of the stock on the last day of the quarterly purchase period. Total purchases through this plan for any employee are limited to a fair market value of $25,000 during any calendar year. At December 29, 2018 , there were approximately 0.2 million remaining authorized, but unissued, shares under this plan. Shares were purchased by employees under this plan as follows (approximate number of shares): 2018– 54,000 ; 2017– 65,000 ; 2016– 63,000 . Options granted to employees to purchase discounted stock under this plan are included in the option activity tables within this note. Additionally, an international subsidiary of the Company maintains a stock purchase plan for its employees. Subject to limitations, employee contributions to this plan are matched 1:1 by the Company. Under this plan, shares were granted by the Company to match an equal number of shares purchased by employees as follows (approximate number of shares): 2018– 63,000 ; 2017– 60,000 ; 2016– 57,000 . Compensation expense for all types of equity-based programs and the related income tax benefit recognized were as follows: (millions) 2018 2017 2016 Pre-tax compensation expense $ 64 $ 71 $ 68 Related income tax benefit $ 16 $ 26 $ 25 As of December 29, 2018 , total stock-based compensation cost related to non-vested awards not yet recognized was $85 million and the weighted-average period over which this amount is expected to be recognized was 2 years. Cash flows realized upon exercise or vesting of stock-based awards in the periods presented are included in the following table. Tax benefits realized upon exercise or vesting of stock-based awards generally represent the tax benefit of the difference between the exercise price and the strike price of the option. Cash used by the Company to settle equity instruments granted under stock-based awards was not material. (millions) 2018 2017 2016 Total cash received from option exercises and similar instruments $ 167 $ 97 $ 368 Tax benefits realized upon exercise or vesting of stock-based awards: Windfall benefits classified as cash flow from operating activities $ 11 $ 4 $ 36 Shares used to satisfy stock-based awards are normally issued out of treasury stock, although management is authorized to issue new shares to the extent permitted by respective plan provisions. Refer to Note 6 for information on shares issued during the periods presented to employees and directors under various long-term incentive plans and share repurchases under the Company’s stock repurchase authorizations. The Company does not currently have a policy of repurchasing a specified number of shares issued under employee benefit programs during any particular time period. Stock options During the periods presented, non-qualified stock options were granted to eligible employees under the 2017 and 2013 Plans with exercise prices equal to the fair market value of the Company’s stock on the grant date, a contractual term of ten years, and a three -year graded vesting period. Management estimates the fair value of each annual stock option award on the date of grant using a lattice-based option valuation model. Composite assumptions are presented in the following table. Weighted-average values are disclosed for certain inputs which incorporate a range of assumptions. Expected volatilities are based principally on historical volatility of the Company’s stock, and to a lesser extent, on implied volatilities from traded options on the Company’s stock. Historical volatility corresponds to the contractual term of the options granted. The Company uses historical data to estimate option exercise and employee termination within the valuation models; separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of options granted represents the period of time that options granted are expected to be outstanding; the weighted-average expected term for all employee groups is presented in the following table. The risk-free rate for periods within the contractual life of the options is based on the U.S. Treasury yield curve in effect at the time of grant. Stock option valuation model assumptions for grants within the year ended: 2018 2017 2016 Weighted-average expected volatility 18.00 % 18.00 % 17.00 % Weighted-average expected term (years) 6.60 6.60 6.88 Weighted-average risk-free interest rate 2.82 % 2.26 % 1.60 % Dividend yield 3.00 % 2.80 % 2.60 % Weighted-average fair value of options granted $ 10.00 $ 10.14 $ 9.44 A summary of option activity for the year ended December 29, 2018 is presented in the following table: Employee and director stock options Shares (millions) Weighted- average exercise price Weighted- average remaining contractual term (yrs.) Aggregate intrinsic value (millions) Outstanding, beginning of year 14 $ 64 Granted 3 70 Exercised (2 ) 58 Forfeitures and expirations (1 ) 71 Outstanding, end of year 14 $ 66 6.3 $ 7 Exercisable, end of year 10 $ 63 5.3 $ 7 Additionally, option activity for the comparable prior year periods is presented in the following table: (millions, except per share data) 2017 2016 Outstanding, beginning of year 15 19 Granted 2 3 Exercised (2 ) (6 ) Forfeitures and expirations (1 ) (1 ) Outstanding, end of year 14 15 Exercisable, end of year 10 8 Weighted-average exercise price: Outstanding, beginning of year $ 62 $ 58 Granted 73 76 Exercised 57 56 Forfeitures and expirations 70 67 Outstanding, end of year $ 64 $ 62 Exercisable, end of year $ 60 $ 58 The total intrinsic value of options exercised during the periods presented was (in millions): 2018– $33 ; 2017– $22 ; 2016– $145 . Other stock-based awards During the periods presented, other stock-based awards consisted principally of executive performance shares and restricted stock granted under the 2017 and 2013 Plans. In the first quarter of 2018, the Company granted performance shares to a limited number of senior executive-level employees, which entitle these employees to receive a specified number of shares of the Company's common stock upon vesting. The number of shares earned could range between 0 and 200% of the target amount depending upon performance achieved over the three year vesting period. The performance conditions of the award include three -year currency-neutral net sales growth and total shareholder return (TSR) of the Company's common stock relative to a select group of peer companies. A Monte Carlo valuation model was used to determine the fair value of the awards. The TSR performance metric is a market condition. Therefore, compensation cost of the TSR condition is fixed at the measurement date and is not revised based on actual performance. The TSR metric was valued as a multiplier of possible levels of currency-neutral comparable operating margin expansion. Compensation cost related to currency-neutral net sales growth performance is revised for changes in the expected outcome. The 2018 target grant currently corresponds to approximately 166,000 shares, with a grant-date fair value of $72 per share. In 2017, the Company granted performance shares to a limited number of senior executive-level employees, which entitle these employees to receive a specified number of shares of the Company's common stock upon vesting. The number of shares earned could range between 0 and 200% of the target amount depending upon performance achieved over the three year vesting period. The performance conditions of the award include three -year currency-neutral comparable operating margin expansion and total shareholder return (TSR) of the Company's common stock relative to a select group of peer companies. The 2017 target grant currently corresponds to approximately 100,000 shares, with a grant-date fair value of $67 per share. In 2016, the Company granted performance shares to a limited number of senior executive-level employees, which entitle these employees to receive a specified number of shares of the Company's common stock upon vesting. The number of shares earned could range between 0 and 200% of the target amount depending upon performance achieved over the three year vesting period. The performance conditions of the award include three -year currency neutral adjusted operating profit growth and TSR of the Company's common stock relative to a select group of peer companies. The 2016 target grant currently corresponds to approximately 129,000 shares, with a grant-date fair value of $80 per share. Based on the market price of the Company’s common stock at year-end 2018, the maximum future value that could be awarded on the vesting date was (in millions): 2018 award– $19 ; 2017 award– $11 ; and 2016 award– $15 . The 2015 performance share award, payable in stock, was settled at 75% of target in February 2018 for a total dollar equivalent of $8 million . The Company also grants restricted stock and restricted stock units to eligible employees under the 2017 Plan. Restrictions with respect to sale or transferability generally lapse after three years and, in the case of restricted stock, the grantee is normally entitled to receive shareholder dividends during the vesting period. Management estimates the fair value of restricted stock grants based on the market price of the underlying stock on the date of grant. A summary of restricted stock and restricted stock unit activity for the year ended December 29, 2018, is presented in the following table: Employee restricted stock and restricted stock units Shares (thousands) Weighted- average grant-date fair value Non-vested, beginning of year 1,673 $ 65 Granted 772 63 Vested (507 ) 59 Forfeited (230 ) 64 Non-vested, end of year 1,708 $ 65 Additionally, restricted stock and restricted stock unit activity for 2017 and 2016 is presented in the following table: Employee restricted stock and restricted stock units 2017 2016 Shares (in thousands): Non-vested, beginning of year 1,166 806 Granted 776 601 Vested (109 ) (116 ) Forfeited (160 ) (125 ) Non-vested, end of year 1,673 1,166 Weighted-average exercise price: Non-vested, beginning of year $ 63 $ 57 Granted 65 70 Vested 58 56 Forfeited 65 63 Non-vested, end of year $ 65 $ 63 The total fair value of restricted stock and restricted stock units vesting in the periods presented was (in millions): 2018– $35 ; 2017– $5 ; 2016– $7 .

Pension Benefits [Abstract]
Pension Benefits [Text Block]	PENSION BENEFITS The Company sponsors a number of U.S. and foreign pension plans to provide retirement benefits for its employees. The majority of these plans are funded or unfunded defined benefit plans, although the Company does participate in a limited number of multiemployer or other defined contribution plans for certain employee groups. See Note 12 for more information regarding the Company’s participation in multiemployer plans. Defined benefits for salaried employees are generally based on salary and years of service, while union employee benefits are generally a negotiated amount for each year of service. The Company uses a December 31 measurement date for these plans and, when necessary, adjusts for plan contributions and significant events between December 31 and its fiscal year-end. In September 2018, the Company recognized a curtailment gain of $30 million as certain European pension plans were frozen as of December 29, 2018 in conjunction with Project K restructuring. In September 2017, the Company amended certain defined benefit pension plans in the U.S. and Canada for salaried employees. As of December 31, 2018, the amendment will freeze the compensation and service periods used to calculate pension benefits for active salaried employees who participate in the affected pension plans. During the third quarter of 2017, the Company recognized related pension curtailment gains totaling $136 million included within Project K restructuring activity. Beginning January 1, 2019, impacted employees will not accrue additional benefits for future service and eligible compensation received under these plans. Concurrently, the Company also amended its 401(k) savings plans effective January 1, 2019, to make previously ineligible salaried U.S. and Canada employees eligible for Company retirement contributions, which range from 3% to 7% of eligible compensation based on the employee’s length of employment. Obligations and funded status The aggregate change in projected benefit obligation, plan assets, and funded status is presented in the following tables.

Information for pension plans with accumulated benefit obligations in excess of plan assets were: (millions) 2018 2017 Projected benefit obligation $ 3,725 $ 4,119 Accumulated benefit obligation $ 3,689 $ 4,051 Fair value of plan assets $ 3,081 $ 3,279 Expense The components of pension expense are presented in the following table. Service cost is recorded in COGS and SGA expense. All other components of net periodic benefit cost are included in OIE. Pension expense for defined contribution plans relates to certain foreign-based defined contribution plans and multiemployer plans in the United States in which the Company participates on behalf of certain unionized workforces. (millions) 2018 2017 2016 Service cost $ 87 $ 96 $ 98 Interest cost 165 164 174 Expected return on plan assets (361 ) (371 ) (352 ) Amortization of unrecognized prior service cost 8 9 13 Recognized net (gain) loss 269 (36 ) 323 Net periodic benefit cost 168 (138 ) 256 Curtailment and special termination benefits (30 ) (151 ) 1 Pension (income) expense: Defined benefit plans 138 (289 ) 257 Defined contribution plans 27 34 36 Total $ 165 $ (255 ) $ 293 The estimated prior service cost for defined benefit pension plans that will be amortized from accumulated other comprehensive income into pension expense over the next fiscal year is approximately $7 million . The Company and certain of its subsidiaries sponsor 401(k) or similar savings plans for active employees. Expense related to these plans was (in millions): 2018 – $38 million ; 2017 – $41 million ; 2016 – $39 million . These amounts are not included in the preceding expense table. Company contributions to these savings plans approximate annual expense. Company contributions to multiemployer and other defined contribution pension plans approximate the amount of annual expense presented in the preceding table. Assumptions The worldwide weighted-average actuarial assumptions used to determine benefit obligations were: 2018 2017 2016 Discount rate 3.9 % 3.3 % 3.6 % Long-term rate of compensation increase 3.8 % 3.9 % 3.9 % The worldwide weighted-average actuarial assumptions used to determine annual net periodic benefit cost were: 2018 2017 2016 Discount rate 3.3 % 3.6 % 4.1 % Long-term rate of compensation increase 3.9 % 3.9 % 3.9 % Long-term rate of return on plan assets 7.4 % 8.1 % 8.1 % To determine the overall expected long-term rate of return on plan assets, the Company models expected returns over a 20-year investment horizon with respect to the specific investment mix of its major plans. The return assumptions used reflect a combination of rigorous historical performance analysis and forward-looking views of the financial markets including consideration of current yields on long-term bonds, price-earnings ratios of the major stock market indices, and long-term inflation. The U.S. model, which corresponds to approximately 72% of consolidated pension and other postretirement benefit plan assets, incorporates a long-term inflation assumption of 2.5% and an active management premium of 1% (net of fees) validated by historical analysis. Similar methods are used for various foreign plans with invested assets, reflecting local economic conditions. The expected rate of return for 2018 of 7.5% for the U.S. plans equated to approximately the 39th percentile expectation. Refer to Note 1 . At the end of 2014, the Company revised its mortality assumption after considering the Society of Actuaries’ (SOA) updated mortality tables and improvement scale, as well as other mortality information available from the Social Security Administration to develop assumptions aligned with the Company’s expectation of future improvement rates. In determining the appropriate mortality assumptions as of December 29, 2018, the Company considered the SOA's 2018 updated improvement scale. The SOA's 2018 scale incorporates changes consistent with the Company's view of future mortality improvements established in 2014. Therefore, the Company adopted the 2018 SOA improvement scales. The change to the mortality assumption decreased the year-end pension liability by $10 million . To conduct the annual review of discount rates, the Company selected the discount rate based on a cash-flow matching analysis using Towers Watson’s proprietary RATE:Link tool and projections of the future benefit payments that constitute the projected benefit obligation for the plans. RATE:Link establishes the uniform discount rate that produces the same present value of the estimated future benefit payments, as is generated by discounting each year’s benefit payments by a spot rate applicable to that year. The measurement dates for the defined benefit plans are consistent with the Company’s fiscal year end. Accordingly, the Company selects yield curves to measure benefit obligations consistent with market indices during December of each year. Plan assets The Company categorized Plan assets within a three level fair value hierarchy described as follows: Investments stated at fair value as determined by quoted market prices (Level 1) include: Cash and cash equivalents: Value based on cost, which approximates fair value. Corporate stock, common: Value based on the last sales price on the primary exchange. Investments stated at estimated fair value using significant observable inputs (Level 2) include: Cash and cash equivalents: Institutional short-term investment vehicles valued daily. Mutual funds: Valued at exit prices quoted in active or non-active markets or based on observable inputs. Collective trusts : Valued at exit prices quoted in active or non-active markets or based on observable inputs. Bonds: Value based on matrices or models from pricing vendors. Limited partnerships: Value based on the ending net capital account balance at year end. Investments stated at estimated fair value using significant unobservable inputs (Level 3) include: Real estate: Value based on the net asset value of units held at year end. The fair value of real estate holdings is based on market data including earnings capitalization, discounted cash flow analysis, comparable sales transactions or a combination of these methods. Buy-in annuity contracts: Value based on the calculated pension benefit obligation covered by the non-participating annuity contracts at year-end. Bonds: Value based on matrices or models from brokerage firms. A limited number of the investments are in default. The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The Company’s practice regarding the timing of transfers between levels is to measure transfers in at the beginning of the month and transfers out at the end of the month. For the year ended December 29, 2018 , the Company had no transfers between Levels 1 and 2. The fair value of Plan assets as of December 29, 2018 summarized by level within the fair value hierarchy are as follows: (millions) Total Level 1 Total Level 2 Total Level 3 Total NAV (practical expedient)(a) Total Cash and cash equivalents $ 75 $ — $ — $ — $ 75 Corporate stock, common: Domestic 412 — — — 412 International 10 1 — — 11 Mutual funds: International equity — 7 — 34 41 Domestic debt — 53 — — 53 Collective trusts: Domestic equity — — — 437 437 International equity — 92 — 1,330 1,422 Other international debt — — — 331 331 Limited partnerships — — — 283 283 Bonds, corporate — 498 — — 498 Bonds, government — 562 — — 562 Bonds, other — 62 — — 62 Real estate — — — 378 378 Other — 55 — 57 112 Total $ 497 $ 1,330 $ — $ 2,850 $ 4,677 (a) Certain assets that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value of Plan assets at December 30, 2017 are summarized as follows: (millions) Total Level 1 Total Level 2 Total Level 3 Total NAV (practical expedient)(a) Total Cash and cash equivalents $ 66 $ 21 $ — $ — $ 87 Corporate stock, common: Domestic 500 — — — 500 International 17 1 — — 18 Mutual funds: International equity — 120 — 38 158 Domestic debt — — — 36 36 Collective trusts: Domestic equity — — — 525 525 International equity — 176 — 1,390 1,566 Other international debt — — — 365 365 Limited partnerships — — — 591 591 Bonds, corporate — 482 — — 482 Bonds, government — 177 — — 177 Bonds, other — 63 — — 63 Real estate — — — 284 284 Other — 128 — 63 191 Total $ 583 $ 1,168 $ — $ 3,292 $ 5,043 (a) Certain assets that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. There were no unfunded commitments to purchase investments at December 29, 2018 or December 30, 2017 . The Company’s investment strategy for its major defined benefit plans is to maintain a diversified portfolio of asset classes with the primary goal of meeting long-term cash requirements as they become due. Assets are invested in a prudent manner to maintain the security of funds while maximizing returns within the Plan’s investment policy. The investment policy specifies the type of investment vehicles appropriate for the Plan, asset allocation guidelines, criteria for the selection of investment managers, procedures to monitor overall investment performance as well as investment manager performance. It also provides guidelines enabling Plan fiduciaries to fulfill their responsibilities. The current weighted-average target asset allocation reflected by this strategy is: equity securities– 45% ; debt securities– 28% ; real estate and other– 27% . Investment in Company common stock represented 1.0% and 1.2% of consolidated plan assets at December 29, 2018 and December 30, 2017 , respectively. Plan funding strategies are influenced by tax regulations and funding requirements. The Company currently expects to contribute, before consideration of incremental discretionary contributions, approximately $7 million to its defined benefit pension plans during 2019. Level 3 gains and losses Changes in the fair value of the Plan’s Level 3 assets are summarized as follows: (millions) Buy-in Annuity Contract Other Total December 31, 2016 $ 131 $ — $ 131 Sales (131 ) — (131 ) Purchases — — — Transfers — — — Realized and unrealized gain — — — Currency translation — — — December 30, 2017 $ — $ — $ — The net change in Level 3 assets includes a gain attributable to the change in unrealized holding gains or losses related to Level 3 assets held at December 29, 2018 and December 30, 2017 was zero. Benefit payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid (in millions): 2019– $261 ; 2020– $261 ; 2021– $269 ; 2022– $275 ; 2023– $281 ; 2024 to 2028– $1,482 .

Nonpension Postretirement And Postemployment Benefits [Abstract]
Nonpension Postretirement And Postemployment Benefits [Text Block]	NONPENSION POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS Postretirement The Company sponsors a number of plans to provide health care and other welfare benefits to retired employees in the United States and Canada, who have met certain age and service requirements. The majority of these plans are funded or unfunded defined benefit plans, although the Company does participate in a limited number of multiemployer or other defined contribution plans for certain employee groups. The Company contributes to voluntary employee benefit association (VEBA) trusts to fund certain U.S. retiree health and welfare benefit obligations. The Company uses a December 31 measurement date for these plans and, when necessary, adjusts for plan contributions and significant events between December 31 and its fiscal year-end. Obligations and funded status The aggregate change in accumulated postretirement benefit obligation, plan assets, and funded status is presented in the following tables. (millions) 2018 2017 Change in accumulated benefit obligation Beginning of year $ 1,190 $ 1,161 Service cost 18 18 Interest cost 36 37 Actuarial (gain) loss (105 ) 29 Benefits paid (67 ) (61 ) Curtailments — 3 Amendments — — Foreign currency adjustments (3 ) 3 End of year $ 1,069 $ 1,190 Change in plan assets Fair value beginning of year $ 1,292 $ 1,136 Actual return on plan assets (91 ) 217 Employer contributions 17 13 Benefits paid (78 ) (74 ) Fair value end of year $ 1,140 $ 1,292 Funded status $ 71 $ 102 Amounts recognized in the Consolidated Balance Sheet consist of Other non-current assets $ 107 $ 144 Other current liabilities (2 ) (2 ) Other liabilities (34 ) (40 ) Net amount recognized $ 71 $ 102 Amounts recognized in accumulated other comprehensive income consist of Prior service credit (68 ) (77 ) Net amount recognized $ (68 ) $ (77 ) Expense Components of postretirement benefit expense (income) were: (millions) 2018 2017 2016 Service cost $ 18 $ 18 $ 21 Interest cost 36 37 39 Expected return on plan assets (94 ) (98 ) (90 ) Amortization of unrecognized prior service credit (9 ) (9 ) (9 ) Recognized net (gain) loss 81 (90 ) (19 ) Net periodic benefit cost 32 (142 ) (58 ) Curtailment — 3 — Postretirement benefit expense: Defined benefit plans 32 (139 ) (58 ) Defined contribution plans 11 16 17 Total $ 43 $ (123 ) $ (41 ) The estimated prior service credit that will be amortized from accumulated other comprehensive income into nonpension postretirement benefit expense over the next fiscal year is expected to be approximately $9 million . Assumptions The weighted-average actuarial assumptions used to determine benefit obligations were: 2018 2017 2016 Discount rate 4.3 % 3.6 % 4.0 % The weighted-average actuarial assumptions used to determine annual net periodic benefit cost were: 2018 2017 2016 Discount rate 3.6 % 4.0 % 4.2 % Long-term rate of return on plan assets 7.5 % 8.5 % 8.5 % The Company determines the overall discount rate and expected long-term rate of return on VEBA trust obligations and assets in the same manner as that described for pension trusts in Note 10 . The assumed health care cost trend rate is 5.5% for 2019, decreasing 0.25% annually to 4.5% by the year 2023 and remaining at that level thereafter. These trend rates reflect the Company’s historical experience and management’s expectations regarding future trends. A one percentage point change in assumed health care cost trend rates would have the following effects: (millions) One percentage point increase One percentage point decrease Effect on total of service and interest cost components $ 6 $ (3 ) Effect on postretirement benefit obligation 97 (67 ) Plan assets The fair value of Plan assets as of December 29, 2018 summarized by level within fair value hierarchy described in Note 10 , are as follows: (millions) Total Level 1 Total Level 2 Total Level 3 Total NAV (practical expedient)(a) Total Cash and cash equivalents $ 2 $ 1 $ — $ — $ 3 Corporate stock, common: Domestic 108 — — — 108 International 5 1 — — 6 Mutual funds: Domestic equity — 37 — — 37 International equity — — — — — Domestic debt — 42 — — 42 Collective trusts: Domestic equity — — — 281 281 International equity — — — 228 228 Limited partnerships — — — 199 199 Bonds, corporate — 95 — — 95 Bonds, government — 50 — — 50 Bonds, other — 7 — — 7 Real estate — — — 83 83 Other — 1 — — 1 Total $ 115 $ 234 $ — $ 791 $ 1,140 (a) Certain assets that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy.

The Company’s asset investment strategy for its VEBA trusts is consistent with that described for its pension trusts in Note 10 . The current target asset allocation is 58% equity securities, 35% debt securities, and 7% real estate. The Company currently expects to contribute approximately $18 million to its VEBA trusts during 2019. There were no Level 3 assets during 2018 and 2017 . Postemployment Under certain conditions, the Company provides benefits to former or inactive employees, including salary continuance, severance, and long-term disability, in the United States and several foreign locations. The Company’s postemployment benefit plans are unfunded. Actuarial assumptions used are generally consistent with those presented for pension benefits in Note 10 . During 2017, the Company reduced its incidence rate assumption based on our review of historical experience, resulting in an actuarial gain of $31 million . The aggregate change in accumulated postemployment benefit obligation and the net amount recognized were: (millions) 2018 2017 Change in accumulated benefit obligation Beginning of year $ 43 $ 87 Service cost 3 6 Interest cost 1 3 Actuarial (gain)loss 3 (45 ) Benefits paid (8 ) (8 ) Amendments — — Foreign currency adjustments — — End of year $ 42 $ 43 Funded status $ (42 ) $ (43 ) Amounts recognized in the Consolidated Balance Sheet consist of Other current liabilities $ (5 ) $ (4 ) Other liabilities (37 ) (39 ) Net amount recognized $ (42 ) $ (43 ) Amounts recognized in accumulated other comprehensive income consist of Net prior service cost $ 4 $ 5 Net experience gain (38 ) (46 ) Net amount recognized $ (34 ) $ (41 ) Components of postemployment benefit expense were: (millions) 2018 2017 2016 Service cost $ 3 $ 6 $ 7 Interest cost 1 3 3 Amortization of unrecognized prior service cost 1 1 1 Recognized net loss (5 ) — 3 Postemployment benefit expense $ — $ 10 $ 14 The estimated net experience gain and net prior service cost that will be amortized from accumulated other comprehensive income into postemployment benefit expense over the next fiscal year is $5 million and $1 million , respectively.

Multipemployer Pension and Post

Multipemployer Pension and Postretirement Plans	12 Months Ended

Multiemployer Plans [Abstract]
Multiemployer Plans [Text Block]	MULTIEMPLOYER PENSION AND POSTRETIREMENT PLANS The Company contributes to multiemployer defined contribution pension and postretirement benefit plans under the terms of collective-bargaining agreements that cover certain unionized employee groups in the United States. Contributions to these plans are included in total pension and postretirement benefit expense as reported in Note 10 and Note 11 , respectively. Pension benefits The risks of participating in multiemployer pension plans are different from single-employer plans. Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan are borne by the remaining participating employers. The Company’s participation in multiemployer pension plans for the year ended December 29, 2018, is outlined in the table below. The “EIN/PN” column provides the Employer Identification Number (EIN) and the three-digit plan number (PN). The most recent Pension Protection Act (PPA) zone status available for 2018 and 2017 is for the plan year-ends as indicated below. The zone status is based on information that the Company received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are between 65 percent and 80 percent funded, and plans in the green zone are at least 80 percent funded. The “FIP/RP Status” column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. In addition to regular plan contributions, the Company may be subject to a surcharge if the plan is in the red zone. The “Surcharge Imposed” column indicates whether a surcharge has been imposed on contributions to the plan. The last column lists the expiration date(s) of the collective-bargaining agreement(s) (CBA) to which the plans are subject. The Company was not listed in the available Forms 5500 of the three plans listed below as providing more than 5 percent of total contributions. At the date the Company’s financial statements were issued, certain Forms 5500 were not available for the plan years ending in 2018.

Over 80 percent of the Company’s participants in this fund are covered by a single CBA that expires on 3/16/2021. (b) During 2017, the Company terminated certain CBAs covered by these funds. Because of the Company's level of continuing involvement in each fund, the Company does not anticipate being subject to a withdrawal liability. The Company does not expect 2019 contributions to be materially different than 2018. (c) During 2017, the Company terminated certain CBAs covered by this fund. As a result, the Company has partially withdrawn from the fund and recognized expense for its estimated withdrawal liability. The Company does not expect 2019 contributions to be materially different than 2018. (d) During 2017, the Company terminated the CBAs covered by certain of these funds. As a result, for the impacted funds, the Company recognized expense for the estimated withdrawal liability and made no contributions in 2018. The Company does not expect 2019 contributions to the remaining funds to be materially different from 2018. As discussed in Note 5, the Company engages in restructuring and cost reduction projects to help achieve its long-term growth targets. Current and future restructuring and cost reduction activities and other strategic initiatives could impact the Company's participation in certain multiemployer plans. In addition to regular contributions, the Company could be obligated to pay additional amounts, known as a withdrawal liability, if a multiemployer pension plan has unfunded vested benefits and the Company decreases or ceases participation in that plan. The Company exited several multiemployer plans associated with Project K restructuring activity and recognized expense as follows (millions): 2018 - $7 ; 2017 - $26 ; 2016 - $0 . These amounts represent management's best estimate; actual results could differ. The cash obligation is payable over a maximum 20-year period; management has not determined the actual period over which the payments will be made. Withdrawal liability payments of $3 million were made during 2018 to multiemployer plans. Withdrawal liability payments made in 2017 and 2016 were immaterial. The Company had withdrawal liabilities of $32 million and $28 million at December 29, 2018 and December 30, 2017, respectively. Postretirement benefits Multiemployer postretirement benefit plans provide health care and other welfare benefits to active and retired employees who have met certain age and service requirements. Contributions to multiemployer postretirement benefit plans were (in millions): 2018 – $11 ; 2017 – $16 ; 2016 – $17 .

Income Tax Disclosure [Text Block]	INCOME TAXES The components of income before income taxes and the provision for income taxes were as follows: (millions) 2018 2017 2016 Income before income taxes United States $ 851 $ 1,097 $ 835 Foreign 478 560 99 1,329 1,657 934 Income taxes Currently payable Federal 7 358 173 State 28 31 26 Foreign 99 79 60 134 468 259 Deferred Federal 109 (41 ) 18 State (59 ) 8 6 Foreign (3 ) (25 ) (48 ) 47 (58 ) (24 ) Total income taxes $ 181 $ 410 $ 235 The difference between the U.S. federal statutory tax rate and the Company’s effective income tax rate was: 2018 2017 2016 U.S. statutory income tax rate 21.0 % 35.0 % 35.0 % Foreign rates varying from U.S. statutory rate (3.0 ) (6.7 ) (5.0 ) Excess tax benefits on share-based compensation (0.3 ) (0.3 ) (3.7 ) State income taxes, net of federal benefit 1.5 1.4 2.4 Cost (benefit) of remitted and unremitted foreign earnings 0.7 0.1 0.1 Legal entity restructuring, deferred tax impact (3.3 ) — — Discretionary pension contributions (2.3 ) — — Net change in valuation allowance 2.0 (0.4 ) 0.5 U.S. deduction for qualified production activities — (1.4 ) (2.8 ) Statutory rate changes, deferred tax impact — (9.0 ) (0.1 ) U.S. deemed repatriation tax (1.2 ) 10.4 — Intangible property transfer — (2.4 ) — Venezuela deconsolidation — — 1.8 Venezuela remeasurement — — 0.4 Other (1.5 ) (1.9 ) (3.4 ) Effective income tax rate 13.6 % 24.8 % 25.2 % As presented in the preceding table, the Company’s 2018 consolidated effective tax rate was 13.6% , as compared to 24.8% in 2017 and 25.2% in 2016. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (Tax Act). The Tax Act makes broad and complex changes to the U.S. tax code which impacted our year ended December 30, 2017 including but not limited to, reducing the corporate tax rate from 35% to 21% , requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that may be electively paid over eight years, and accelerating first year expensing of certain capital expenditures. Shortly after the Tax Act was enacted, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118), which provides guidance on accounting for the Tax Act’s impact. SAB 118 provided a measurement period, which in no case should extend beyond one year from the Tax Act enactment date, during which a company may complete the accounting for the impacts of the Tax Act under ASC Topic 740. The Company's 2018 income tax provision includes an $11 million reduction to income tax expense due to changes in estimates related to the Tax Act. The reduction is primarily related to a $16 million reduction in the transition tax estimate and $5 million of additional tax associated primarily with the final assessment of changes in our indefinite reinvestment assertion and resulting tax. The Company's 2017 year end income tax provision includes $8 million of net additional income tax expense during the quarter ended December 30, 2017, driven by the reduction in the U.S. corporate tax rate and the transition tax on foreign earnings. Transition tax on foreign earnings: The transition tax is a tax on the previously untaxed accumulated and current earnings and profits of certain of our foreign subsidiaries. In order to determine the amount of the transition tax, the Company must determine, in addition to other factors, the amount of post-1986 earnings and profits (E&P) of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. E&P is similar to retained earnings of the subsidiary, but requires other adjustments to conform to U.S. tax rules. As of December 30, 2017, based on accumulated foreign earnings and profits of approximately $2.6 billion , which are primarily in Europe, the Company was able to make a reasonable estimate of the transition tax and recorded a transition tax obligation of $157 million , which the Company expects to elect to pay over eight years. In the third quarter of 2018, the Company recorded a $16 million reduction to the transition tax liability and tax expense based on updated estimates of E&P. During the fourth quarter of 2018, the Company, as part of completing its accounting under SAB 118, revised its estimate of the transition tax liability to $94 million , and recorded $47 million of tax reserves related to uncertainty in our interpretation of the statute and associated regulations. Indefinite reinvestment assertion: Prior to the Tax Act, we treated a significant portion of our undistributed foreign earnings as indefinitely reinvested. In light of the Tax Act, which included a new territorial tax regime, as of the period ended December 30, 2017, Management determined that the Company would analyze its global capital structure and working capital strategy and considered the indefinite reinvestment assertion to be provisional under SAB 118. In the fourth quarter of 2018, we finished analyzing our global capital structure and working capital strategy and determined that $2.4 billion of foreign earnings as of December 30, 2017 were no longer considered to be indefinitely invested. Accordingly, income tax expense of approximately $5 million was recorded in the fourth quarter of 2018. We have completed the assessment and accounting under SAB 118 for our indefinite investment assertion. Reduction in U.S. Corporate Tax Rate: The tax provision as of December 30, 2017, included a tax benefit of $149 million for the remeasurement of certain deferred tax assets and liabilities to reflect the corporate income tax rate reduction impact to the Company's net deferred tax balances. The accounting for the reduction in the U.S. Corporate Tax rate was considered complete in the fourth quarter of 2017. The Tax Act also created a new requirement that certain income earned by foreign subsidiaries, known as global intangible low-tax income (GILTI), must be included in the gross income of their U.S. shareholder. During the fourth quarter of 2018, the Company elected to treat the tax effect of GILTI as a current-period expense when incurred. In conjunction with SAB 118, we have completed the accounting for the Tax Act in the fourth quarter 2018. The 2018 effective income tax rate benefited from the reduction of the U.S. corporate tax rate as well as a $11 million reduction of income tax expense due to changes in estimates related to the Tax Act, the impact of discretionary pension contributions totaling $250 million in 2018, which were designated as 2017 tax year contributions, and a $44 million discrete tax benefit as a result of the remeasurement of deferred taxes following a legal entity restructuring. As of December 29, 2018, approximately $700 million of unremitted earnings were considered indefinitely reinvested. The unrecognized deferred tax liability for these earnings is estimated at approximately $20 million . However, this estimate could change based on the manner in which the outside basis difference associated with these earnings reverses. The 2017 effective income tax rate benefited from a deferred tax benefit of $39 million resulting from intercompany transfers of intellectual property under the application of the newly adopted standard. See discussion regarding the adoption of ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory , in Note 1. The 2016 effective income tax rate benefited from excess tax benefits from share-based compensation totaling $36 million for federal, state, and foreign income taxes. During 2016, as described in Note 16 , the Company deconsolidated its Venezuelan operations resulting in a pre-tax charge of $72 million with no significant associated tax benefit. Management monitors the Company’s ability to utilize certain future tax deductions, operating losses and tax credit carryforwards, prior to expiration. Changes resulting from management’s assessment will result in impacts to deferred tax assets and the corresponding impacts on the effective income tax rate. Valuation allowances were recorded to reduce deferred tax assets to an amount that will, more likely than not, be realized in the future. The total tax benefit of carryforwards at year-end 2018 and 2017 were $270 million and $239 million , respectively, with related valuation allowances at year-end 2018 and 2017 of $166 million and $153 million , respectively. Of the total carryforwards at year-end 2018 , substantially all will expire after 2022. The following table provides an analysis of the Company’s deferred tax assets and liabilities as of year-end 2018 and 2017 . Deferred tax liabilities increased in 2018 due primarily to the additional investment and consolidation of Multipro resulting in a deferred tax liability of $253 million .

The entire adjustment of $15 million was offset by a corresponding valuation allowance because it is not expected to be used in the future. During 2016, the Company increased its deferred tax assets by $34 million relating to a revision of 2014 foreign loss carryforwards. The entire adjustment of $34 million was offset by a corresponding adjustment in the valuation allowance because it is not expected to be used in the future. These adjustments are not considered material to the previously issued or current year financial statements. Also during 2016, the Company increased its deferred tax assets by $26 million related to a foreign loss carryforward. The entire amount was offset by a corresponding valuation allowance because it is not expected to be used in the future. Uncertain tax positions The Company is subject to federal income taxes in the U.S. as well as various state, local, and foreign jurisdictions. The Company’s 2018 provision for U.S. federal income taxes represents approximately 65% of the Company’s consolidated income tax provision. The Company was chosen to participate in the Internal Revenue Service (IRS) Compliance Assurance Program (CAP) beginning with the 2008 tax year. As a result, with limited exceptions, the Company is no longer subject to U.S. federal examinations by the IRS for years prior to 2018. The Company is under examination for income and non-income tax filings in various state and foreign jurisdictions. As of December 29, 2018 , the Company has classified $12 million of unrecognized tax benefits as a current liability. Management’s estimate of reasonably possible changes in unrecognized tax benefits during the next twelve months is comprised of the current liability balance expected to be settled within one year, offset by approximately $4 million of projected additions related primarily to ongoing intercompany transfer pricing activity. Management is currently unaware of any issues under review that could result in significant additional payments, accruals, or other material deviation in this estimate. Following is a reconciliation of the Company’s total gross unrecognized tax benefits as of the years ended December 29, 2018 , December 30, 2017 and December 31, 2016 . For the 2018 year, approximately $86 million represents the amount that, if recognized, would affect the Company’s effective income tax rate in future periods.

For the year ended December 29, 2018, the Company paid tax-related interest totaling $2 million and recognized $3 million of tax-related interest increasing the accrual balance to $22 million at year end. For the year ended December 30, 2017, the Company recognized $2 million of tax-related interest resulting in an accrual balance of $21 million at year-end. For the year ended December 31, 2016, the Company recognized $2 million of tax-related interest resulting in an accrual balance of $19 million at year-end.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Fair Value [Text Block]	DERIVATIVE INSTRUMENTS AND FAIR VALUE MEASUREMENTS The Company is exposed to certain market risks such as changes in interest rates, foreign currency exchange rates, and commodity prices, which exist as a part of its ongoing business operations. Management uses derivative financial and commodity instruments, including futures, options, and swaps, where appropriate, to manage these risks. Instruments used as hedges must be effective at reducing the risk associated with the exposure being hedged and must be designated as a hedge at the inception of the contract. The Company designates derivatives as cash flow hedges, fair value hedges, net investment hedges, and uses other contracts to reduce volatility in interest rates, foreign currency and commodities. As a matter of policy, the Company does not engage in trading or speculative hedging transactions. Total notional amounts of the Company’s derivative instruments as of December 29, 2018 and December 30, 2017 were as follows: (millions) 2018 2017 Foreign currency exchange contracts $ 1,863 $ 2,172 Cross-currency contracts 1,197 — Interest rate contracts 1,608 2,250 Commodity contracts 417 544 Total $ 5,085 $ 4,966 Following is a description of each category in the fair value hierarchy and the financial assets and liabilities of the Company that were included in each category at December 29, 2018 and December 30, 2017 , measured on a recurring basis. Level 1 — Financial assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market. For the Company, level 1 financial assets and liabilities consist primarily of commodity derivative contracts. Level 2 — Financial assets and liabilities whose values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability. For the Company, level 2 financial assets and liabilities consist of interest rate swaps and over-the-counter commodity and currency contracts. The Company’s calculation of the fair value of interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve. Over-the-counter commodity derivatives are valued using an income approach based on the commodity index prices less the contract rate multiplied by the notional amount. Foreign currency contracts are valued using an income approach based on forward rates less the contract rate multiplied by the notional amount. Cross-currency contracts are valued based on changes in the spot rate at the time of valuation compared to the spot rate at the time of execution, as well as the change in the interest differential between the two currencies. The Company’s calculation of the fair value of level 2 financial assets and liabilities takes into consideration the risk of nonperformance, including counterparty credit risk. Level 3 — Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability. The Company did not have any level 3 financial assets or liabilities as of December 29, 2018 or December 30, 2017 . The following table presents assets and liabilities that were measured at fair value in the Consolidated Balance Sheet on a recurring basis as of December 29, 2018 and December 30, 2017 : Derivatives designated as hedging instruments 2018 2017 (millions) Level 1 Level 2 Total Level 1 Level 2 Total Assets: Cross currency contracts: Other Assets $ — $ 79 $ 79 $ — $ — $ — Interest rate contracts (a): Other assets — 17 17 — — — Total assets $ — $ 96 $ 96 $ — $ — $ — Liabilities: Interest rate contracts: Other liabilities (a) — (22 ) (22 ) — (54 ) (54 ) Total liabilities $ — $ (22 ) $ (22 ) $ — $ (54 ) $ (54 ) (a) The fair value of the related hedged portion of the Company’s long-term debt, a level 2 liability, was $1.6 billion and $2.3 billion as of December 29, 2018 and December 30, 2017, respectively.

The carrying value of this debt was $2.6 billion and $2.7 billion as of December 29, 2018 and December 30, 2017 , respectively. The following amounts were recorded on the Consolidated Balance Sheet related to cumulative basis adjustments for existing fair value hedges as of December 29, 2018 and December 30, 2017 . (millions) Line Item in the Consolidated Balance Sheet in which the hedged item is included Carrying amount of the hedged liabilities Cumulative amount of fair value hedging adjustment included in the carrying amount of the hedged liabilities (a) December 29, December 30, December 29, December 30, Interest rate contracts Current maturities of long-term debt $ 503 $ 402 $ 3 $ 2 Interest rate contracts Long-term debt $ 3,354 $ 3,481 $ (18 ) $ (22 ) (a) The current maturities of hedged long-term debt includes $3 million and $2 million of hedging adjustment on discontinued hedging relationships as of December 29, 2018 and December 30, 2017 . The hedged long-term debt includes $(12) million and $32 million of hedging adjustment on discontinued hedging relationships as of December 29, 2018 and December 30, 2017 , respectively. The Company has elected to not offset the fair values of derivative assets and liabilities executed with the same counterparty that are generally subject to enforceable netting agreements. However, if the Company were to offset and record the asset and liability balances of derivatives on a net basis, the amounts presented in the Consolidated Balance Sheet as of December 29, 2018 and December 30, 2017 would be adjusted as detailed in the following table: As of December 29, 2018 Gross Amounts Not Offset in the Consolidated Balance Sheet Amounts Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Received/ Posted Net Amount Total asset derivatives $ 102 $ (27 ) $ (2 ) $ 73 Total liability derivatives $ (35 ) $ 27 $ — $ (8 ) As of December 30, 2017 Gross Amounts Not Offset in the Consolidated Balance Sheet Amounts Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Received/ Posted Net Amount Total asset derivatives $ 16 $ (15 ) $ — $ 1 Total liability derivatives $ (75 ) $ 15 $ 37 $ (23 ) The effect of derivative instruments on the Consolidated Statement of Income for the years ended December 29, 2018 and December 30, 2017 were as follows: Derivatives and non-derivatives in net investment hedging relationships (millions) Gain (loss) recognized in AOCI Gain (loss) excluded from assessment of hedge effectiveness Location of gain (loss) in income of excluded component 2018 2017 2018 2017 Foreign currency denominated long-term debt $ 129 $ (316 ) $ — $ — Cross-currency contracts 79 — 16 — Interest expense Total $ 208 $ (316 ) $ 16 $ — Derivatives not designated as hedging instruments (millions) Location of gain (loss) recognized in income Gain (loss) recognized in income 2018 2017 Foreign currency exchange contracts COGS $ 19 $ (8 ) Foreign currency exchange contracts SGA 1 (1 ) Foreign currency exchange contracts OIE — (10 ) Commodity contracts COGS (23 ) (18 ) Commodity contracts SGA — (15 ) Total $ (3 ) $ (52 ) The effect of fair value and cash flow hedge accounting on the Consolidated Income Statement for the year-to-date periods ended December 29, 2018 and December 30, 2017 : December 29, 2018 December 30, 2017 (millions) Interest Expense COGS Interest Expense Other Income / (Expense) Total amounts of income and expense line items presented in the Consolidated Income Statement in which the effects of fair value or cash flow hedges are recorded $ 287 $ 8,155 $ 256 $ 526 Gain (loss) on fair value hedging relationships: Interest contracts: Hedged items (5 ) — 22 — Derivatives designated as hedging instruments 9 — (4 ) (1 ) Gain (loss) on cash flow hedging relationships: Interest contracts: Amount of gain (loss) reclassified from AOCI into income (8 ) — (10 ) — Foreign exchange contracts: Amount of gain (loss) reclassified from AOCI into income — 1 — — During the next 12 months, the Company expects $7 million of net deferred losses reported in accumulated other comprehensive income (AOCI) at December 29, 2018 to be reclassified to income, assuming market rates remain constant through contract maturities. Certain of the Company’s derivative instruments contain provisions requiring the Company to post collateral on those derivative instruments that are in a liability position if the Company’s credit rating falls below BB+ (S&P), or Baa1 (Moody’s). The fair value of all derivative instruments with credit-risk-related contingent features in a liability position on December 29, 2018 was $3 million . If the credit-risk-related contingent features were triggered as of December 29, 2018 , the Company would be required to post additional collateral of $3 million . In addition, certain derivative instruments contain provisions that would be triggered in the event the Company defaults on its debt agreements. There were no collateral posting requirements as of December 29, 2018 triggered by credit-risk-related contingent features. Other fair value measurements Fair Value Measurements on a Nonrecurring Basis As part of Project K, the Company has consolidated the usage of and has disposed certain long-lived assets, including manufacturing facilities and Corporate owned assets over the term of the program. See Note 5 for more information regarding Project K. During the year-to-date period ended December 29, 2018 , long-lived assets of $19 million related to a manufacturing facility in the Company's North America Other reportable segment, were written down to an estimated fair value of $5 million due to Project K activities. The Company's calculation of the fair value of these long-lived assets is based on level 3 inputs, including market comparables, market trends and the condition of the assets. During 2017, there were no long-lived asset impairments related to Project K. Financial instruments The carrying values of the Company’s short-term items, including cash, cash equivalents, accounts receivable, accounts payable, notes payable and current maturities of long-term debt approximate fair value. The fair value of the Company’s long-term debt, which are level 2 liabilities, is calculated based on broker quotes. The fair value and carrying value of the Company's long-term debt was $8.2 billion as of December 29, 2018 . Counterparty credit risk concentration The Company is exposed to credit loss in the event of nonperformance by counterparties on derivative financial and commodity contracts. Management believes a concentration of credit risk with respect to derivative counterparties is limited due to the credit ratings and use of master netting and reciprocal collateralization agreements with the counterparties and the use of exchange-traded commodity contracts. Master netting agreements apply in situations where the Company executes multiple contracts with the same counterparty. If these counterparties fail to perform according to the terms of derivative contracts, this could result in a loss to the Company. As of December 29, 2018 , there were no counterparties that represented a significant concentration of credit risk to the Company. For certain derivative contracts, reciprocal collateralization agreements with counterparties call for the posting of collateral in the form of cash, treasury securities or letters of credit if a fair value loss position to the Company or its counterparties exceeds a certain amount. In addition, the company is required to maintain cash margin accounts in connection with its open positions for exchange-traded commodity derivative instruments executed with the counterparty that are subject to enforceable netting agreements. As of December 29, 2018 , the Company had no collateral posting requirements related to reciprocal collateralization agreements and collected approximately $20 million of collateral related to reciprocal collaterization agreements which is reflected as an increase in other liabilities. As of December 29, 2018 , the Company posted $18 million in margin deposits for exchange-traded commodity derivative instruments, which was reflected as an increase in accounts receivable, net. Management believes concentrations of credit risk with respect to accounts receivable is limited due to the generally high credit quality of the Company’s major customers, as well as the large number and geographic dispersion of smaller customers. However, the Company conducts a disproportionate amount of business with a small number of large multinational grocery retailers, with the five largest accounts encompassing approximately 20% of consolidated trade receivables at December 29, 2018 . Refer to Note 1 for disclosures regarding the Company’s accounting policies for derivative instruments.

Loss Contingencies [Abstract]
Contingencies Disclosure [Text Block]	CONTINGENCIES The Company is subject to various legal proceedings, claims, and governmental inspections or investigations in the ordinary course of business covering matters such as general commercial, governmental regulations, antitrust and trade regulations, product liability, environmental, intellectual property, workers’ compensation, employment and other actions. These matters are subject to uncertainty and the outcome is not predictable with assurance. The Company uses a combination of insurance and self-insurance for a number of risks, including workers’ compensation, general liability, automobile liability and product liability. The Company has established accruals for certain matters where losses are deemed probable and reasonably estimable. There are other claims and legal proceedings pending against the Company for which accruals have not been established. It is reasonably possible that some of these matters could result in an unfavorable judgment against the Company and could require payment of claims in amounts that cannot be estimated at December 29, 2018. Based upon current information, management does not expect any of the claims or legal proceedings pending against the Company to have a material impact on the Company’s consolidated financial statements.

Foreign Currency [Abstract]
Foreign Currency Disclosure [Text Block]	VENEZUELA Effective as of December 31, 2016, the Company concluded that it no longer met the accounting criteria for consolidation of its Venezuela subsidiary due to a loss of control over the Venezuelan operations. Historically, the Company took steps to reduce its reliance on imports in order to run its operations in Venezuela without the need of foreign currency, including the substitution, where possible, of imported ingredients, materials and parts with locally produced inputs. However, the availability of certain key raw materials, even if locally sourced, was largely controlled by the local government and the Company experienced an increase in government intervention and restrictions on the local supply of these key raw materials. During the fourth quarter of 2016, the Company experienced increased disruptions and restrictions in the procurement of certain locally sourced raw materials and packaging due to local government actions, which greatly diminished the Venezuelan operation’s ability to produce products for sale, culminating in record low production volume and capacity utilization during the quarter. These supply chain disruptions, along with other factors such as the worsening economic environment in Venezuela and the limited access to dollars to import goods through the use of any of the available currency mechanisms, impaired the Company’s ability to effectively operate and fully control its Venezuelan subsidiary. As of December 31, 2016, the Company deconsolidated and changed to the cost method of accounting for its Venezuelan subsidiary. During the fourth quarter of 2016, the Company recorded a $72 million pre-tax charge in Other income (expense), net as it fully impaired the value of its cost method investment in Venezuela. The deconsolidation charge included the historical cumulative translation losses of approximately $63 million related to the Company's Venezuelan operations that had previously been recorded in accumulated other comprehensive losses within equity. Beginning in fiscal year 2017, the Company no longer included the financial statements of its Venezuelan subsidiary within its consolidated financial statements.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	REPORTABLE SEGMENTS Kellogg Company is the world’s leading producer of cereal, second largest producer of crackers and cookies and a leading producer of savory snacks and frozen foods. Additional product offerings include toaster pastries, cereal bars, fruit-flavored snacks, veggie foods, and noodles. Kellogg products are manufactured and marketed globally. Principal markets for these products include the United States and United Kingdom. For the periods presented, the Company has the following reportable segments: U.S. Snacks; U.S. Morning Foods; U.S. Specialty Channels; North America Other; Europe; Latin America; and Asia Pacific. The Company manages its operations through ten operating segments that are based on product category or geographic location. These operating segments are evaluated for similarity with regards to economic characteristics, products, production processes, types or classes of customers, distribution methods and regulatory environments to determine if they can be aggregated into reportable segments. The reportable segments are discussed in greater detail below. U.S. Snacks includes crackers, cookies, cereal bars, savory snacks and fruit-flavored snacks. The U.S. Morning Foods reportable segment includes primarily cereal and toaster pastries. U.S. Specialty Channels primarily represents food away from home channels, including food service, convenience, vending, Girl Scouts and food manufacturing. The food service business is mostly non-commercial, serving institutions such as schools and hospitals. The convenience business includes traditional convenience stores as well as alternate retailing outlets. North America Other includes the U.S. Frozen, Kashi, Canada, and RX operating segments. As these operating segments are not considered economically similar enough to aggregate with other operating segments and are immaterial for separate disclosure, they have been grouped together as a single reportable segment. The three remaining reportable segments are based on geographic location — Europe which consists principally of European countries, the Middle East and Northern Africa; Latin America which consists of Central and South America and includes Mexico; and Asia Pacific which consists of Sub-Saharan Africa, Australia and other Asian and Pacific markets. In November 2018, the Company announced plans to reorganize Kellogg North America effective at the beginning of fiscal 2019. As a result of these changes, the Company has re-evaluated its North American operating segments and determined that effective at the beginning of fiscal 2019, the Company will have the following reportable segments: North America, Europe, Latin America, and Asia Middle East and Africa (AMEA). Additionally, the Company announced the transfer of the Middle East, Northern Africa, and Turkey businesses out of the Europe reportable segment and into Asia Pacific. The Asia Pacific reportable segment will be renamed Kellogg AMEA, at the beginning of fiscal 2019. Also in November 2018, the Company announced that it will begin to explore the potential sale of the cookie, fruit snacks, pie crusts, and ice cream cone businesses. These businesses are primarily reported as part of the U.S. Snacks, U.S. Specialty Channels and North America Other reportable segments and represent approximately $900 million in net sales for the year ended December 29, 2018. At December 29, 2018, these businesses were not classified as held for sale based upon the status of the process and board authorization. The measurement of reportable segment results is based on segment operating profit which is generally consistent with the presentation of operating profit in the Consolidated Statement of Income. Reportable segment results were as follows: (millions) 2018 2017 2016 Net sales U.S. Snacks $ 2,957 $ 3,110 $ 3,197 U.S. Morning Foods 2,643 2,709 2,917 U.S. Specialty Channels 1,235 1,242 1,207 North America Other 1,853 1,612 1,593 Europe 2,395 2,291 2,383 Latin America 947 944 772 Asia Pacific 1,517 946 896 Consolidated $ 13,547 $ 12,854 $ 12,965 Operating profit U.S. Snacks $ 446 $ 138 $ 325 U.S. Morning Foods 478 567 597 U.S. Specialty Channels 251 312 279 North America Other 222 229 181 Europe 297 276 208 Latin America 102 108 84 Asia Pacific 128 84 69 Total Reportable Segments 1,924 1,714 1,743 Corporate (218 ) (327 ) (260 ) Consolidated $ 1,706 $ 1,387 $ 1,483 Depreciation and amortization (a) U.S. Snacks $ 138 $ 146 $ 159 U.S. Morning Foods 127 120 122 U.S. Specialty Channels 12 13 11 North America Other 64 51 56 Europe 80 80 114 Latin America 37 37 22 Asia Pacific 55 33 30 Total Reportable Segments 513 480 514 Corporate 3 1 3 Consolidated $ 516 $ 481 $ 517 (a) Includes asset impairment charges as discussed in Note 14 .

Accounting Policies (Policies)

Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of accounting [Policy Text Block]	The consolidated financial statements include the accounts of the Kellogg Company, those of the subsidiaries that it controls due to ownership of a majority voting interest (Kellogg or the Company). The Company continually evaluates its involvement with variable interest entities (VIEs) to determine whether it has variable interests and is the primary beneficiary of the VIE. When these criteria are met, the Company is required to consolidate the VIE. The Company’s share of earnings or losses of nonconsolidated affiliates is included in its consolidated operating results using the equity method of accounting when it is able to exercise significant influence over the operating and financial decisions of the affiliate. The Company uses the cost method of accounting if it is not able to exercise significant influence over the operating and financial decisions of the affiliate. Intercompany balances and transactions are eliminated. The Company’s fiscal year normally ends on the Saturday closest to December 31 and as a result, a 53rd week is added approximately every sixth year. The Company’s 2018, 2017 and 2016 fiscal years each contained 52 weeks and ended on December 29, 2018 , December 30, 2017 , and December 31, 2016, respectively.
Use of estimates [Policy Text Block]	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods reported. Actual results could differ from those estimates.
Cash and cash equivalents [Policy Text Block]	Highly liquid investments with remaining stated maturities of three months or less when purchased are considered cash equivalents and recorded at cost.
Accounts receivables [Policy Text Block]	Accounts receivable consists principally of trade receivables, which are recorded at the invoiced amount, net of allowances for doubtful accounts and prompt payment discounts. Trade receivables do not bear interest. The allowance for doubtful accounts represents management’s estimate of the amount of probable credit losses in existing accounts receivable, as determined from a review of past due balances and other specific account data. Account balances are written off against the allowance when management determines the receivable is uncollectible. As of year-end 2018 , the Company did not have off-balance sheet credit exposure related to its customers. As of year-end 2017 , the Company's off-balance sheet credit exposure related to its customers was immaterial. Please refer to Note 2 for information on sales of accounts receivable.
Inventories [Policy Text Block]	Inventories are valued at the lower of cost or net realizable value. Cost is determined on an average cost basis.
Property [Policy Text Block]	The Company’s property consists mainly of plants and equipment used for manufacturing activities. These assets are recorded at cost and depreciated over estimated useful lives using straight-line methods for financial reporting and accelerated methods, where permitted, for tax reporting. Major property categories are depreciated over various periods as follows (in years): manufacturing machinery and equipment 15 - 30 ; office equipment 5 ; computer equipment and capitalized software 3 - 7 ; building components 20 ; building structures 10 - 50 . Cost includes interest associated with significant capital projects. Plant and equipment are reviewed for impairment when conditions indicate that the carrying value may not be recoverable. Such conditions include an extended period of idleness or a plan of disposal. Assets to be disposed of at a future date are depreciated over the remaining period of use. Assets to be sold are written down to realizable value at the time the assets are being actively marketed for sale and a sale is expected to occur within one year. There were no assets held for sale at the year-end 2018 . As of year-end 2017 , the carrying value of assets held for sale was immaterial.
Goodwill and other intangible assets [Policy Text Block]	Goodwill and indefinite-lived intangibles are not amortized, but are tested at least annually for impairment of value and whenever events or changes in circumstances indicate the carrying amount of the asset may be impaired. An intangible asset with a finite life is amortized on a straight-line basis over the estimated useful life, which materially approximates the pattern of economic benefit. For the goodwill impairment test, the fair value of the reporting units are estimated based on market multiples. This approach employs market multiples based on either sales or earnings before interest, taxes, depreciation and amortization for companies that are comparable to the Company’s reporting units. In the event the fair value determined using the market multiple approach is close to carrying value, the Company may supplement the fair value determination using discounted cash flows. The assumptions used for the impairment test are consistent with those utilized by a market participant performing similar valuations for the Company’s reporting units. Similarly, impairment testing of other intangible assets requires a comparison of carrying value to fair value of that particular asset. Fair values of non-goodwill intangible assets are based primarily on projections of future cash flows to be generated from that asset. For instance, cash flows related to a particular trademark would be based on a projected royalty stream attributable to branded product sales, discounted at rates consistent with rates used by market participants. These estimates are made using various inputs including historical data, current and anticipated market conditions, management plans, and market comparables.
Accounts payable [Policy Text Block]	The Company has agreements with third parties to provide accounts payable tracking systems which facilitate participating suppliers’ ability to monitor and, if elected, sell payment obligations from the Company to designated third-party financial institutions. Participating suppliers may, at their sole discretion, make offers to sell one or more payment obligations of the Company prior to their scheduled due dates at a discounted price to participating financial institutions. The Company’s goal is to capture overall supplier savings, in the form of payment terms or vendor funding, and the agreements facilitate the suppliers’ ability to sell payment obligations, while providing them with greater working capital flexibility. The Company has no economic interest in the sale of these suppliers’ receivables and no direct financial relationship with the financial institutions concerning these services. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to sell amounts under the arrangements. However, the Company’s right to offset balances due from suppliers against payment obligations is restricted by the agreements for those payment obligations that have been sold by suppliers. As of December 29, 2018 , $893 million of the Company’s outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $701 million of those payment obligations to participating financial institutions. As of December 30, 2017 , $850 million of the Company’s outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $674 million of those payment obligations to participating financial institutions.
Revenue recognition [Policy Text Block]	The Company recognizes sales upon delivery of its products to customers. Revenue, which includes shipping and handling charges billed to the customer, is reported net of applicable discounts, returns, allowances, and various government withholding taxes. Methodologies for determining these provisions are dependent on local customer pricing and promotional practices, which range from contractually fixed percentage price reductions to reimbursement based on actual occurrence or performance. Where applicable, future reimbursements are estimated based on a combination of historical patterns and future expectations regarding specific in-market product performance. The Company recognizes revenue from the sale of food products which are sold to retailers through direct sales forces, broker and distributor arrangements. The Company also recognizes revenue from the license of our trademarks granted to third parties who uses these trademarks on their merchandise and revenue from hauling services provided to third parties within certain markets. Revenue from these licenses and hauling services is not material to the Company. Contract balances recognized in the current period that are not the result of current period performance are not material to the Company. The Company also does not incur costs to obtain or fulfill contracts. Performance obligations The Company recognizes revenue when (or as) performance obligations are satisfied by transferring control of the goods to customers. Control is transferred upon delivery of the goods to the customer. At the time of delivery, the customer is invoiced with payment terms which are commensurate with the customer’s credit profile. Shipping and/or handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. The Company assesses the goods and services promised in its customers’ purchase orders and identifies a performance obligation for each promise to transfer a good or service (or bundle of goods or services) that is distinct. To identify the performance obligations, the Company considers all the goods or services promised, whether explicitly stated or implied based on customary business practices. For a purchase order that has more than one performance obligation, the Company allocates the total consideration to each distinct performance obligation on a relative standalone selling price basis. Significant Judgments The Company offers various forms of trade promotions and the methodologies for determining these provisions are dependent on local customer pricing and promotional practices, which range from contractually fixed percentage price reductions to provisions based on actual occurrence or performance. Where applicable, future provisions are estimated based on a combination of historical patterns and future expectations regarding specific in-market product performance. Our promotional activities are conducted either through the retail trade or directly with consumers and include activities such as in-store displays and events, feature price discounts, consumer coupons, contests and loyalty programs. The costs of these activities are generally recognized at the time the related revenue is recorded, which normally precedes the actual cash expenditure. The recognition of these costs therefore requires management judgment regarding the volume of promotional offers that will be redeemed by either the retail trade or consumer. These estimates are made using various techniques including historical data on performance of similar promotional programs. Differences between estimated expense and actual redemptions are normally immaterial and recognized as a change in management estimate in a subsequent period.
Advertising and promotion [Policy Text Block]	The Company expenses production costs of advertising the first time the advertising takes place. Advertising expense is classified in selling, general and administrative (SGA) expense. The Company classifies promotional payments to its customers, the cost of consumer coupons, and other cash redemption offers in net sales. Promotional allowances are estimated using various techniques including historical cash expenditure and redemption experience and patterns. Differences between estimated expense and actual redemptions are normally immaterial and recognized as a change in management estimate in a subsequent period. The liability associated with these promotions are recorded in other current liabilities. The cost of promotional package inserts is recorded in cost of goods sold (COGS). Other types of consumer promotional expenditures are recorded in SGA expense.
Research and development [Policy Text Block]	The costs of research and development (R&D) are expensed as incurred and are classified in SGA expense. R&D includes expenditures for new product and process innovation, as well as significant technological improvements to existing products and processes. The Company’s R&D expenditures primarily consist of internal salaries, wages, consulting, and supplies attributable to time spent on R&D activities. Other costs include depreciation and maintenance of research facilities and equipment, including assets at manufacturing locations that are temporarily engaged in pilot plant activities.
Share-based compensation [Policy Text Block]	The Company uses stock-based compensation, including stock options, restricted stock, restricted stock units, and executive performance shares, to provide long-term performance incentives for its global workforce. The Company classifies pre-tax stock compensation expense in SGA and COGS within its corporate operations. Expense attributable to awards of equity instruments is recorded in capital in excess of par value in the Consolidated Balance Sheet. Certain of the Company’s stock-based compensation plans contain provisions that prorate vesting of awards upon retirement, disability, or death of eligible employees and directors. A stock-based award is considered vested for expense attribution purposes when the employee’s retention of the award is no longer contingent on providing subsequent service. Accordingly, the Company recognizes compensation cost immediately for awards granted to retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period. The Company recognizes compensation cost for stock option awards that have a graded vesting schedule on a straight-line basis over the requisite service period for the entire award.
Income taxes [Policy Text Block]	The Company recognizes uncertain tax positions based on a benefit recognition model. Provided that the tax position is deemed more likely than not of being sustained, the Company recognizes the largest amount of tax benefit that is greater than 50 percent likely of being ultimately realized upon settlement. The tax position is derecognized when it is no longer more likely than not of being sustained. The Company classifies income tax-related interest and penalties as interest expense and SGA expense, respectively, on the Consolidated Statement of Income. The current portion of the Company’s unrecognized tax benefits is presented in the Consolidated Balance Sheet in other current assets and other current liabilities, and the amounts expected to be settled after one year are recorded in other assets and other liabilities. Management monitors the Company’s ability to utilize certain future tax deductions, operating losses and tax credit carryforwards, prior to expiration as well as the reinvestment assertion regarding our undistributed foreign earnings. Changes resulting from management’s assessment will result in impacts to deferred tax assets and the corresponding impacts on the effective income tax rate. Valuation allowances were recorded to reduce deferred tax assets to an amount that will, more likely than not, be realized in the future. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act includes a provision designed to tax currently global intangible low taxed income (GILTI) starting in 2018. Under the provision, a U.S. shareholder is required to include in gross income the amount of its GILTI, which is 50% of the excess of the shareholder’s net tested income of its controlled foreign corporation over the deemed tangible income return. The amount of GILTI included by a U.S. shareholder is computed by aggregating all controlled foreign corporations (CFC). Shareholders are allowed to claim a foreign tax credit for 80 percent of the taxes paid or accrued with respect to the tested income of each CFC, subject to some limitations. The Financial Accounting Standards Board (FASB) staff has indicated that a company should make and disclose a policy election as to whether it will (1) recognize deferred taxes for basis differences expected to reverse as GILTI or (2) account for GILTI as a period cost if and when incurred. During 2018, the Company elected to account for the GILTI as a period cost and has included an estimate for GILTI in its effective tax rate.
Derivatives instruments[Policy Text Block]	The fair value of derivative instruments is recorded in other current assets, other assets, other current liabilities or other liabilities. Gains and losses representing either hedge ineffectiveness, hedge components excluded from the assessment of effectiveness, or hedges of translational exposure are recorded in the Consolidated Statement of Income in other income (expense), net (OIE) or interest expense. In the Consolidated Statement of Cash Flows, settlements of cash flow and fair value hedges are classified as an operating activity; settlements of all other derivative instruments, including instruments for which hedge accounting has been discontinued, are classified consistent with the nature of the instrument. Cash flow hedges. Qualifying derivatives are accounted for as cash flow hedges when the hedged item is a forecasted transaction. Gains and losses on these instruments are recorded in other comprehensive income until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive income (loss) (AOCI) to the Consolidated Statement of Income on the same line item as the underlying transaction. Fair value hedges. Qualifying derivatives are accounted for as fair value hedges when the hedged item is a recognized asset, liability, or firm commitment. Gains and losses on these instruments are recorded in earnings, offsetting gains and losses on the hedged item. Net investment hedges. Qualifying derivative and nonderivative financial instruments are accounted for as net investment hedges when the hedged item is a nonfunctional currency investment in a subsidiary. Gains and losses on these instruments are included in foreign currency translation adjustments in AOCI. Derivatives not designated for hedge accounting. Gains and losses on these instruments are recorded in the Consolidated Statement of Income, on the same line item as the underlying hedged item. Foreign currency exchange risk. The Company is exposed to fluctuations in foreign currency cash flows related primarily to third-party purchases, intercompany transactions and when applicable, nonfunctional currency denominated third-party debt. The Company is also exposed to fluctuations in the value of foreign currency investments in subsidiaries and cash flows related to repatriation of these investments. Additionally, the Company is exposed to volatility in the translation of foreign currency denominated earnings to U.S. dollars. Management assesses foreign currency risk based on transactional cash flows and translational volatility and may enter into forward contracts, options, and currency swaps to reduce fluctuations in long or short currency positions. Forward contracts and options are generally less than 18 months duration. Currency swap agreements are established in conjunction with the term of underlying debt issues. For foreign currency cash flow and fair value hedges, the assessment of effectiveness is generally based on changes in spot rates. Changes in time value are reported in OIE. Interest rate risk. The Company is exposed to interest rate volatility with regard to future issuances of fixed rate debt and existing and future issuances of variable rate debt. The Company periodically uses interest rate swaps, including forward-starting swaps, to reduce interest rate volatility and funding costs associated with certain debt issues, and to achieve a desired proportion of variable versus fixed rate debt, based on current and projected market conditions. Fixed-to-variable interest rate swaps are accounted for as fair value hedges and the assessment of effectiveness is based on changes in the fair value of the underlying debt, using incremental borrowing rates currently available on loans with similar terms and maturities. Price risk. The Company is exposed to price fluctuations primarily as a result of anticipated purchases of raw and packaging materials, fuel, and energy. The Company has historically used the combination of long-term contracts with suppliers, and exchange-traded futures and option contracts to reduce price fluctuations in a desired percentage of forecasted raw material purchases over a duration of generally less than 18 months.
Pension benefits, nonpension postretirement and postemployment benefits [Policy Text Block]	The Company sponsors a number of U.S. and foreign plans to provide pension, health care, and other welfare benefits to retired employees, as well as salary continuance, severance, and long-term disability to former or inactive employees. The recognition of benefit expense is based on actuarial assumptions, such as discount rate, long-term rate of compensation increase, and long-term rate of return on plan assets and health care cost trend rate. Service cost is reported in COGS and SGA expense on the Consolidated Statement of Income. All other components of net periodic pension cost are included in OIE. Postemployment benefits. The Company recognizes an obligation for postemployment benefit plans that vest or accumulate with service. Obligations associated with the Company’s postemployment benefit plans, which are unfunded, are included in other current liabilities and other liabilities on the Consolidated Balance Sheet. All gains and losses are recognized over the average remaining service period of active plan participants. Postemployment benefits that do not vest or accumulate with service or benefits to employees in excess of those specified in the respective plans are expensed as incurred. Pension and nonpension postretirement benefits. The Company recognizes actuarial gains and losses in operating results in the year in which they occur. Experience gains and losses are recognized annually as of the measurement date, which is the Company’s fiscal year-end, or when remeasurement is otherwise required under generally accepted accounting principles. The Company uses the fair value of plan assets to calculate the expected return on plan assets. Reportable segments are allocated service cost. All other components of pension and postretirement benefit expense, including interest cost, expected return on assets, prior service cost, and experience gains and losses are considered unallocated corporate costs and are not included in the measure of reportable segment operating results. See Note 18 for more information on reportable segments. Management reviews the Company’s expected long-term rates of return annually; however, the benefit trust investment performance for one particular year does not, by itself, significantly influence this evaluation. The expected rates of return are generally not revised provided these rates fall between the 25th and 75th percentile of expected long-term returns, as determined by the Company’s modeling process. For defined benefit pension and postretirement plans, the Company records the net overfunded or underfunded position as a pension asset or pension liability on the Consolidated Balance Sheet.
New Accounting Pronouncements, Policy [Policy Text Block]	New accounting standards Income Taxes. In October 2016, the Financial Accounting Standards Board (FASB), as part of their simplification initiative, issued an Accounting Standards Update (ASU) to improve the accounting for income tax consequences of intra-entity transfers of assets other than inventory. Current Generally Accepted Accounting Principles (GAAP) prohibit recognition of current and deferred income taxes for intra-entity asset transfers until the asset has been sold to an outside party, which is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. The amendments in the ASU eliminate the exception, such that entities should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. That is, early adoption should be the first interim period if an entity issues interim financial statements. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the period of adoption. The Company early adopted the ASU in the first quarter of 2017. As a result of intercompany transfers of intellectual property, the Company recorded a $39 million reduction in income tax expense during the year ended December 30, 2017. Upon adoption, there was no cumulative effect adjustment to retained earnings. Simplifying the Measurement of Inventory. In July 2015, the FASB issued an ASU to simplify the measurement of inventory. The ASU requires that inventory be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted the updated standard in the first quarter of 2017 with no material impact to the financial statements, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. In August 2017, the FASB issued an ASU intended to simplify hedge accounting by better aligning an entity’s financial reporting for hedging relationships with its risk management activities. The ASU also simplifies the application of the hedge accounting guidance. The new guidance is effective fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. For cash flow hedges existing at the adoption date, the standard requires adoption on a modified retrospective basis with a cumulative-effect adjustment to the Consolidated Balance Sheet as of the beginning of the year of adoption. The amendments to presentation guidance and disclosure requirements are required to be adopted prospectively. The Company adopted the ASU in the first quarter of 2018. The impact of adoption was immaterial to the financial statements. Improving the Presentation of net Periodic Pension Cost and net Periodic Postretirement Benefit Cost. In March 2017, the FASB issued an ASU to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The amendments in this ASU should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. The Company adopted the ASU in the first quarter of 2018. Refer to Impacts to Previously Reported Results below for the impact of adoption of the standard on our consolidated financial statements. Simplifying the test for goodwill impairment. In January 2017, the FASB issued an ASU to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. The ASU is effective for an entity's annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The amendments in this ASU should be applied on a prospective basis. The Company adopted the ASU in the first quarter of 2018 with no impact. Statement of Cash Flows. In August 2016, the FASB issued an ASU to provide various cash flow statement classification guidance for certain cash receipts and payments of which the following amendments were most applicable to the Company: (a) debt prepayment or extinguishment costs; (b) contingent consideration payments made after a business combination; (c) insurance settlement proceeds; (d) distributions from equity method investees; (e) beneficial interests in securitization transactions and (f) application of the predominance principle for cash receipts and payments with aspects of more than one class of cash flows. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period, in which case adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The amendments in this ASU should be applied retrospectively. The Company adopted the new ASU in the first quarter of 2018. Refer to Impacts to Previously Reported Results below for the impact of adoption of the standard on our consolidated financial statements. Recognition and measurement of financial assets and liabilities. In January 2016, the FASB issued an ASU which requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in net income and which updates certain presentation and disclosure requirements. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption can be elected for all financial statements of fiscal years and interim periods that have not yet been issued or that have not yet been made available for issuance. Entities should apply the update by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The Company adopted the updated standard in the first quarter of 2018. The impact of adoption was immaterial to the financial statements. Revenue from contracts with customers. In May 2014, the FASB issued an ASU, as amended, which provides guidance for accounting for revenue from contracts with customers. The core principle of this ASU is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services. To achieve that core principle, an entity would be required to apply the following five steps: 1) identify the contract(s) with a customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The Company adopted the updated standard in the first quarter of 2018 using the full retrospective method and restated previously reported amounts. In connection with the adoption, the Company made reclassification of certain customer allowances. The adoption effects relate to the timing of recognition and classification of certain promotional allowances. The updated revenue standard also required additional disaggregated revenue disclosures. Refer to Impacts to Previously Reported Results below for the impact of adoption of the standard on our consolidated financial statements. Practical expedients The Company elected the following practical expedients in accordance with ASU 2014-09: • Significant financing component - The Company elected not to adjust the promised amount of consideration for the effects of a significant financing component as the Company expects, at contract inception, that the period between the transfer of a promised good or service to a customer and when the customer pays for that good or service will be one year or less. • Shipping and handling costs - The Company elected to account for shipping and handling activities that occur before the customer has obtained control of a good as fulfillment activities (i.e., an expense) rather than as a promised service. • Measurement of transaction price - The Company has elected to exclude from the measurement of transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from a customer for sales taxes. Impacts to Previously Reported Results Adoption of the standards related to revenue recognition, pension and cash flow impacted our previously reported 2017 results as follows: (Dollars in millions, except per share data) Year ended December 30, 2017 Consolidated Statement of Income Previously Reported Revenue Recognition ASU Pension ASU Restated Net sales $ 12,923 $ (69 ) $ — $ 12,854 Cost of goods sold $ 7,901 $ (71 ) $ 325 $ 8,155 Selling, general and administrative expense $ 3,076 $ 19 $ 217 $ 3,312 Other income (expense), net $ (16 ) $ — $ 542 $ 526 Income taxes $ 412 $ (2 ) $ — $ 410 Net income $ 1,269 $ (15 ) $ — $ 1,254 Per share amounts: Basic earnings $ 3.65 $ (0.04 ) $ — $ 3.61 Diluted earnings $ 3.62 $ (0.04 ) $ — $ 3.58 (Dollars in millions, except per share data) As of December 30, 2017 Consolidated Balance Sheet Previously Reported Revenue Recognition ASU Restated Other assets $ 1,026 $ 1 $ 1,027 Other current liabilities $ 1,431 $ 43 $ 1,474 Deferred income taxes $ 363 $ (8 ) $ 355 Retained earnings $ 7,103 $ (34 ) $ 7,069 (Dollars in millions, except per share data) Year ended December 30, 2017 Consolidated Statement of Cash Flows Previously Reported Revenue Recognition ASU Cash Flow ASU Restated Net income $ 1,269 $ (15 ) $ — $ 1,254 Deferred income taxes $ (56 ) $ (2 ) $ — $ (58 ) Trade receivables $ (57 ) $ — $ (1,243 ) $ (1,300 ) All other current assets and liabilities, net $ (30 ) $ 17 $ — $ (13 ) Net cash provided by (used in) operating activities $ 1,646 $ — $ (1,243 ) $ 403 Collections of deferred purchase price on securitized trade receivables $ — $ — $ 1,243 $ 1,243 Net cash provided by (used in) investing activities $ (1,094 ) $ — $ 1,243 $ 149 Adoption of the standards related to revenue recognition, pension and cash flow impacted our previously reported 2016 results as follows: (Dollars in millions, except per share data) Year ended December 31, 2016 Consolidated Statement of Income Previously Reported Revenue Recognition ASU Pension ASU Restated Net sales $ 13,014 $ (49 ) $ — $ 12,965 Cost of goods sold $ 8,259 $ (73 ) $ (55 ) $ 8,131 Selling, general and administrative expense $ 3,360 $ 17 $ (26 ) $ 3,351 Other income (expense), net $ (62 ) $ — $ (81 ) $ (143 ) Income taxes $ 233 $ 2 $ — $ 235 Net income $ 695 $ 5 $ — $ 700 Per share amounts: Basic earnings $ 1.98 $ 0.01 $ — $ 1.99 Diluted earnings $ 1.96 $ 0.01 $ — $ 1.97 (Dollars in millions, except per share data) Year ended December 31, 2016 Consolidated Statement of Cash Flows Previously Reported Revenue Recognition ASU Cash Flow ASU Restated Net income $ 695 $ 5 $ — $ 700 Deferred income taxes $ (26 ) $ 2 $ — $ (24 ) Other $ (62 ) $ — $ 144 $ 82 Trade receivables $ 21 $ — $ (501 ) $ (480 ) All other current assets and liabilities, net $ 53 $ (7 ) $ — $ 46 Net cash provided by (used in) operating activities $ 1,628 $ — $ (357 ) $ 1,271 Collections of deferred purchase price on securitized trade receivables $ — $ — $ 501 $ 501 Net cash provided by (used in) investing activities $ (893 ) $ — $ 501 $ (392 ) Debt extinguishment costs $ — $ — $ (144 ) $ (144 ) Net cash provided by (used in) financing activities $ (642 ) $ — $ (144 ) $ (786 ) Accounting standards to be adopted in future periods Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. In February 2018, the FASB issued an ASU permitting a company to reclassify the disproportionate income tax effects of the Tax Cuts and Jobs Act of 2017 on items within accumulated other comprehensive income (AOCI). The reclassification is optional. Regardless of whether or not a company opts to make the reclassification, the new guidance requires all companies to include certain disclosures in their financial statements. The guidance is effective for all fiscal years beginning after December 15, 2018. Early adoption is permitted. The Company will adopt the ASU in the first quarter of 2019. Leases. In February 2016, the FASB issued an ASU which will require the recognition of lease assets and lease liabilities by lessees for all leases with terms greater than 12 months. The distinction between finance leases and operating leases will remain, with similar classification criteria as current GAAP to distinguish between capital and operating leases. The principal difference from current guidance is that the lease assets and lease liabilities arising from operating leases will be recognized on the Consolidated Balance Sheet. Lessor accounting remains substantially similar to current GAAP. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company will adopt the ASU in the first quarter of 2019, and expects to elect certain practical expedients permitted under the transition guidance. Additionally, the Company will elect the optional transition method that allows for a cumulative-effect adjustment in the period of adoption and will not restate prior periods. The Company continues to evaluate the effect of adoption to its Consolidated Financial Statements and disclosures, however the Company currently estimates total assets and liabilities will increase approximately $450 million to $500 million upon adoption. This estimate could change as the Company continues to progress with implementation and will also fluctuate based on the lease portfolio and discount rates as of the adoption date. The Company does not expect a material impact to the Company’s Consolidated Statements of Income or Cash Flows. Cloud Computing Arrangements. In August 2018, the FASB issued ASU 2018-15: Intangibles - Goodwill and Other - Internal-Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The ASU allows companies to capitalize implementation costs incurred in a hosting arrangement that is a service contract over the term of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019 and can be applied retrospectively or prospectively. Early adoption is permitted. The Company is currently assessing when to adopt the ASU and the impact of adoption. Compensation Retirement Benefits. In August 2018, the FASB issued ASU 2018-14: Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. The ASU removed disclosures that no longer are considered cost beneficial, clarified the specific requirements of disclosures, and added disclosure requirements identified as relevant. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020 and can be applied retrospectively or prospectively. Early adoption is permitted. The Company is currently assessing when to adopt the ASU and the impact of adoption.

[1]	During 2017, the Company increased deferred tax assets by $15 million related to a foreign loss carryforward related to the acquisition of a majority ownership interest in a natural, bio-organic certified breakfast company. The entire adjustment of $15 million was offset by a corresponding valuation allowance because it is not expected to be used in the future. During 2016, the Company increased its deferred tax assets by $34 million relating to a revision of 2014 foreign loss carryforwards. The entire adjustment of $34 million was offset by a corresponding adjustment in the valuation allowance because it is not expected to be used in the future. These adjustments are not considered material to the previously issued or current year financial statements. Also during 2016, the Company increased its deferred tax assets by $26 million related to a foreign loss carryforward.
