Accounting Policies [Abstract]
Basis of presentation [Policy Text Block]	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 and the accounts of the variable interest entities (VIEs) of which Kellogg Company is the primary beneficiary (Kellogg or the Company). The Company continually evaluates its involvement with 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 2013 and 2012 fiscal years each contained 52 weeks and ended on December 28, 2013 and December 29, 2012, respectively. The Company's 2014 fiscal year ended on January 3, 2015, and included a 53rd week. While quarters normally consist of 13-week periods, the fourth quarter of fiscal 2014 included a 14th week.
Use of estimates [Policy Text Block]	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 [Policy Text Block]	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 [Policy Text Block]	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. The Company does not have off-balance sheet credit exposure related to its customers.
Inventories [Policy Text Block]	Inventories Inventories are valued at the lower of cost or market. Cost is determined on an average cost basis.
Property [Policy Text Block]	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 5-30; office equipment 4-5; computer equipment and capitalized software 3-7; building components 15-25; building structures 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. As of year-end 2014 and 2013, the carrying value of assets held for sale was insignificant.
Goodwill and other intangible assets [Policy Text Block]	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. 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 earnings before interest, taxes, depreciation and amortization and earnings 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]	Accounts payable Beginning in 2014, the Company has an agreement with a third party to provide an accounts payable tracking system which facilitates participating suppliers' ability to monitor and, if elected, sell to designated third-party financial institutions, payment obligations of the Company. 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 in entering into this agreement is to capture overall supplier savings, in the form of pricing, payment terms or vendor funding, created by facilitating suppliers' ability to sell receivables, while providing them with greater working capital flexibility. We have 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 this arrangement. However, the Company's right to offset balances due from suppliers against payment obligations is restricted by this agreement for those payment obligations that have been sold by suppliers. As of January 3, 2015, $236 million of the Company's outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $184 million of those payment obligations to participating financial institutions.
Revenue recognition [Policy Text Block]	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 provisions for 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.
Advertising and promotion [Policy Text Block]	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. 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]	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 [Policy Text Block]	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 principally in SGA expense 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 accelerate 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. Corporate income tax benefits realized upon exercise or vesting of an award in excess of that previously recognized in earnings (“windfall tax benefit”) is recorded in other financing activities in the Consolidated Statement of Cash Flows. Realized windfall tax benefits are credited to capital in excess of par value in the Consolidated Balance Sheet. Realized shortfall tax benefits (amounts which are less than that previously recognized in earnings) are first offset against the cumulative balance of windfall tax benefits, if any, and then charged directly to income tax expense. The Company currently has sufficient cumulative windfall tax benefits to absorb arising shortfalls, such that earnings were not affected during the periods presented. Correspondingly, the Company includes the impact of pro forma deferred tax assets (i.e., the “as if” windfall or shortfall) for purposes of determining assumed proceeds in the treasury stock calculation of diluted earnings per share.
Income taxes [Policy Text Block]	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. Income taxes are provided on the portion of foreign earnings that is expected to be remitted to and taxable in the United States.
Derivative instruments [Policy Text Block]	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). 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. Other contracts. The Company periodically enters into foreign currency forward contracts and options to reduce volatility in the translation of foreign currency earnings to U.S. dollars. Gains and losses on these instruments are recorded in OIE, generally reducing the exposure to translation volatility during a full-year period. 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. Certain commodity contracts are accounted for as cash flow hedges, while others are marked to market through earnings. The assessment of effectiveness for exchange-traded instruments is based on changes in futures prices. The assessment of effectiveness for over-the-counter transactions is based on changes in designated indices.
Pension benefits, nonpension postretirement and postemployment benefits [Policy Text Block]	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, long-term rate of return on plan assets and health care cost trend rate, and is reported in COGS and SGA expense on the Consolidated Statement of Income. 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 and amortization of prior service cost. All other components of pension and postretirement benefit expense, including interest cost, expected return on assets, and experience gains and losses are considered unallocated corporate costs and are not included in the measure of reportable segment operating results. See Note 16 for more information on reportable segments. Assumed mortality rates of plan participants are a critical estimate in measuring the expected payments a participant will receive over their lifetime and the amount of expense recognized. On October 27, 2014, the Society of Actuaries' (SOA) published updated mortality tables and an updated improvement scale, which both reflect improved longevity. In determining the appropriate mortality assumptions as of January 3, 2015, the Company considered the SOA's updated mortality tables 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. 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 [Policy Text Block]	New accounting standards Presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. In July 2013, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) which provides guidance on financial statement presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This ASU is expected to eliminate diversity in practice resulting from lack of previously existing guidance. It applies to all entities with unrecognized tax benefits that also have tax loss or tax credit carryforwards in the same tax jurisdiction as of the reporting date. The Company adopted the revised guidance in 2014 with no significant impact to the Consolidated Financial Statements. Reporting of amounts reclassified out of Accumulated Other Comprehensive Income. In February 2013, the FASB issued an updated accounting standard requiring entities to present information about reclassifications out of accumulated other comprehensive income in a single note or on the face of the financial statements. The Company adopted the updated standard in 2013. Indefinite-lived intangible asset impairment testing. In July 2012, the FASB issued an ASU to allow entities the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative indefinite-lived intangible asset impairment test. Under the updated standard an entity would not be required to perform the quantitative impairment test unless the entity determines, based on a qualitative assessment, that it is more likely than not that an indefinite-lived intangible asset is impaired. The Company adopted the revised guidance in 2013, with no impact to the Consolidated Financial Statements. Accounting standards to be adopted in future periods In May 2014, the FASB issued an ASU 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 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 ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is not permitted. Entities will have the option to apply the final standard retrospectively or use a modified retrospective method, recognizing the cumulative effect of the ASU in retained earnings at the date of initial application. An entity will not restate prior periods if it uses the modified retrospective method, but will be required to disclose the amount by which each financial statement line item is affected in the current reporting period by the application of the ASU as compared to the guidance in effect prior to the change, as well as reasons for significant changes. The Company will adopt the updated standard in the first quarter of 2017. The Company is currently evaluating the impact that implementing this ASU will have on its financial statements and disclosures, as well as whether it will use the retrospective or modified retrospective method of adoption.

Basis of presentation [Policy Text Block]

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 and the accounts of the variable interest entities (VIEs) of which Kellogg Company is the primary beneficiary (Kellogg or the Company). The Company continually evaluates its involvement with 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 2013 and 2012 fiscal years each contained 52 weeks and ended on December 28, 2013 and December 29, 2012, respectively. The Company's 2014 fiscal year ended on January 3, 2015, and included a 53rd week. While quarters normally consist of 13-week periods, the fourth quarter of fiscal 2014 included a 14th week.

Use of estimates [Policy Text Block]

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 [Policy Text Block]

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 [Policy Text Block]

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. The Company does not have off-balance sheet credit exposure related to its customers.

Inventories [Policy Text Block]

Inventories

Inventories are valued at the lower of cost or market. Cost is determined on an average cost basis.

Property [Policy Text Block]

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 5-30; office equipment 4-5; computer equipment and capitalized software 3-7; building components 15-25; building structures 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. As of year-end 2014 and 2013, the carrying value of assets held for sale was insignificant.

Goodwill and other intangible assets [Policy Text Block]

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.

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 earnings before interest, taxes, depreciation and amortization and earnings 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]

Accounts payable

Beginning in 2014, the Company has an agreement with a third party to provide an accounts payable tracking system which facilitates participating suppliers' ability to monitor and, if elected, sell to designated third-party financial institutions, payment obligations of the Company. 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 in entering into this agreement is to capture overall supplier savings, in the form of pricing, payment terms or vendor funding, created by facilitating suppliers' ability to sell receivables, while providing them with greater working capital flexibility. We have 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 this arrangement. However, the Company's right to offset balances due from suppliers against payment obligations is restricted by this agreement for those payment obligations that have been sold by suppliers. As of January 3, 2015, $236 million of the Company's outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $184 million of those payment obligations to participating financial institutions.

Revenue recognition [Policy Text Block]

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 provisions for 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.

Advertising and promotion [Policy Text Block]

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. 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]

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 [Policy Text Block]

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 principally in SGA expense 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 accelerate 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.

Corporate income tax benefits realized upon exercise or vesting of an award in excess of that previously recognized in earnings (“windfall tax benefit”) is recorded in other financing activities in the Consolidated Statement of Cash Flows. Realized windfall tax benefits are credited to capital in excess of par value in the Consolidated Balance Sheet. Realized shortfall tax benefits (amounts which are less than that previously recognized in earnings) are first offset against the cumulative balance of windfall tax benefits, if any, and then charged directly to income tax expense. The Company currently has sufficient cumulative windfall tax benefits to absorb arising shortfalls, such that earnings were not affected during the periods presented. Correspondingly, the Company includes the impact of pro forma deferred tax assets (i.e., the “as if” windfall or shortfall) for purposes of determining assumed proceeds in the treasury stock calculation of diluted earnings per share.

Income taxes [Policy Text Block]

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.

Income taxes are provided on the portion of foreign earnings that is expected to be remitted to and taxable in the United States.

Derivative instruments [Policy Text Block]

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). 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.

Other contracts. The Company periodically enters into foreign currency forward contracts and options to reduce volatility in the translation of foreign currency earnings to U.S. dollars. Gains and losses on these instruments are recorded in OIE, generally reducing the exposure to translation volatility during a full-year period.

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.

Certain commodity contracts are accounted for as cash flow hedges, while others are marked to market through earnings. The assessment of effectiveness for exchange-traded instruments is based on changes in futures prices. The assessment of effectiveness for over-the-counter transactions is based on changes in designated indices.

Pension benefits, nonpension postretirement and postemployment benefits [Policy Text Block]

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, long-term rate of return on plan assets and health care cost trend rate, and is reported in COGS and SGA expense on the Consolidated Statement of Income.

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 and amortization of prior service cost. All other components of pension and postretirement benefit expense, including interest cost, expected return on assets, and experience gains and losses are considered unallocated corporate costs and are not included in the measure of reportable segment operating results. See Note 16 for more information on reportable segments.

Assumed mortality rates of plan participants are a critical estimate in measuring the expected payments a participant will receive over their lifetime and the amount of expense recognized. On October 27, 2014, the Society of Actuaries' (SOA) published updated mortality tables and an updated improvement scale, which both reflect improved longevity. In determining the appropriate mortality assumptions as of January 3, 2015, the Company considered the SOA's updated mortality tables 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.

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 [Policy Text Block]

New accounting standards

Presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. In July 2013, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) which provides guidance on financial statement presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This ASU is expected to eliminate diversity in practice resulting from lack of previously existing guidance. It applies to all entities with unrecognized tax benefits that also have tax loss or tax credit carryforwards in the same tax jurisdiction as of the reporting date. The Company adopted the revised guidance in 2014 with no significant impact to the Consolidated Financial Statements.

Reporting of amounts reclassified out of Accumulated Other Comprehensive Income. In February 2013, the FASB issued an updated accounting standard requiring entities to present information about reclassifications out of accumulated other comprehensive income in a single note or on the face of the financial statements. The Company adopted the updated standard in 2013.

Indefinite-lived intangible asset impairment testing. In July 2012, the FASB issued an ASU to allow entities the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative indefinite-lived intangible asset impairment test. Under the updated standard an entity would not be required to perform the quantitative impairment test unless the entity determines, based on a qualitative assessment, that it is more likely than not that an indefinite-lived intangible asset is impaired. The Company adopted the revised guidance in 2013, with no impact to the Consolidated Financial Statements.

Accounting standards to be adopted in future periods

In May 2014, the FASB issued an ASU 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 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 ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is not permitted. Entities will have the option to apply the final standard retrospectively or use a modified retrospective method, recognizing the cumulative effect of the ASU in retained earnings at the date of initial application. An entity will not restate prior periods if it uses the modified retrospective method, but will be required to disclose the amount by which each financial statement line item is affected in the current reporting period by the application of the ASU as compared to the guidance in effect prior to the change, as well as reasons for significant changes. The Company will adopt the updated standard in the first quarter of 2017. The Company is currently evaluating the impact that implementing this ASU will have on its financial statements and disclosures, as well as whether it will use the retrospective or modified retrospective method of adoption.
