Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation The consolidated financial statements present the accounts of Kimberly-Clark Corporation and all subsidiaries in which it has a controlling financial interest as if they were a single economic entity in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions and accounts are eliminated in consolidation. The terms "Corporation," "Kimberly-Clark," "we," "our," and "us" refer to Kimberly-Clark Corporation and all subsidiaries in which it has a controlling financial interest. Dollar amounts are reported in millions, except per share dollar amounts, unless otherwise noted. In prior years, we followed an accounting practice whereby costs associated with sales of K-C Professional dispensers were classified as a reduction in revenue, similar to sales incentives. Effective January 1, 2018, we changed this practice and now classify these costs as cost of products sold. This change resulted in an immaterial increase in net sales and cost of products sold and all applicable prior period amounts included in this filing have been recast accordingly. Subsequent to the issuance of the December 31, 2017 financial statements, we identified an error in the recording of treasury stock retirements and disbursement transactions. We have assessed these errors and determined they are immaterial as the correction does not result in any change to total stockholders’ equity or in the number of treasury shares reported and does not impact the consolidated statements of income, comprehensive income or cash flow for any period presented. The correction of the cumulative error has been recorded as an adjustment to December 31, 2015 retained earnings, treasury stock and additional paid in capital in the amounts of $960, $968 and $8, respectively, and the prior period financial statements have been revised to reflect the correct amounts. Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Actual results could differ from these estimates, and changes in these estimates are recorded when known. Estimates are used in accounting for, among other things, sales incentives and trade promotion allowances, employee postretirement benefits, and deferred income taxes and potential assessments. Cash Equivalents Cash equivalents are short-term investments with an original maturity date of three months or less. Inventories and Distribution Costs Most U.S. inventories are valued at the lower of cost, using the Last-In, First-Out ("LIFO") method, or market. The balance of the U.S. inventories and inventories of consolidated operations outside the U.S. are valued at the lower of cost or net realizable value using either the First-In, First-Out ("FIFO") or weighted-average cost methods. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Distribution costs are classified as cost of products sold. Property and Depreciation Property, plant and equipment are stated at cost and are depreciated on the straight-line method. Buildings are depreciated over their estimated useful lives, primarily 40 years. Machinery and equipment are depreciated over their estimated useful lives, primarily ranging from 16 to 20 years. Purchases of computer software, including external costs and certain internal costs (including payroll and payroll-related costs of employees) directly associated with developing significant computer software applications for internal use, are capitalized. Computer software costs are amortized on the straight-line method over the estimated useful life of the software, which generally does not exceed 5 years. Estimated useful lives are periodically reviewed and, when warranted, changes are made to them. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. An impairment loss would be indicated when estimated undiscounted future cash flows from the use and eventual disposition of an asset group, which are identifiable and largely independent of the cash flows of other asset groups, are less than the carrying amount of the asset group. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset group over its fair value. Fair value is measured using discounted cash flows or independent appraisals, as appropriate. When property is sold or retired, the cost of the property and the related accumulated depreciation are removed from the consolidated balance sheet and any gain or loss on the transaction is included in income. Goodwill and Other Intangible Assets Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not amortized, but rather is assessed for impairment annually and whenever events and circumstances indicate that impairment may have occurred. Impairment testing compares the reporting unit carrying amount, including goodwill, with its fair value. If the reporting unit carrying amount, including goodwill, exceeds its fair value, a goodwill impairment charge for the excess amount above fair value would be recorded. In our evaluation of goodwill impairment, we have the option to first assess qualitative factors such as macroeconomic, industry and competitive conditions, legal and regulatory environments, historical and projected financial performance, significant changes in the reporting unit and the magnitude of excess fair value over carrying amount from the previous quantitative impairment testing. If the qualitative assessment determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a quantitative impairment test using discounted cash flows to estimate fair value must be performed. On the other hand, if the qualitative assessment determines that it is more likely than not that the fair value of a reporting unit is more than its carrying value, then further quantitative testing is not required. For 2018, we completed the required annual assessment of goodwill for impairment for all of our reporting units using a qualitative assessment as of the first day of the third quarter, and determined that it is more likely than not that the fair value is more than the carrying amount for each of our reporting units. Intangible assets with finite lives are amortized over their estimated useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. An impairment loss would be indicated when estimated undiscounted future cash flows from the use of the asset are less than its carrying amount. An impairment loss would be measured as the difference between the fair value (based on discounted future cash flows) and the carrying amount of the asset. Estimated useful lives range from 2 to 20 years for trademarks and 5 to 15 years for patents, developed technologies and other intangible assets. Investments in Equity Companies Investments in companies which we do not control but over which we have the ability to exercise significant influence and that, in general, are at least 20 percent-owned by us, are stated at cost plus equity in undistributed net income. These investments are evaluated for impairment when warranted. An impairment loss would be recorded whenever a decline in value of an equity investment below its carrying amount is determined to be other than temporary. In judging "other than temporary," we would consider the length of time and extent to which the fair value of the equity company investment has been less than the carrying amount, the near-term and longer-term operating and financial prospects of the equity company, and our longer-term intent of retaining the investment in the equity company. Revenue Recognition Sales revenue is recognized at the time of product shipment or delivery, depending on when control passes, to unaffiliated customers, and when all of the following have occurred: a firm sales agreement is in place, pricing is fixed or determinable, and collection is reasonably assured. Sales are reported net of returns, consumer and trade promotions, rebates and freight allowed. Taxes imposed by governmental authorities on our revenue-producing activities with customers, such as sales taxes and value-added taxes, are excluded from net sales. Sales Incentives and Trade Promotion Allowances The cost of promotion activities provided to customers is classified as a reduction in sales revenue. In addition, effective January 1, 2018 for interim reporting, the estimated redemption value of consumer coupons and related expense are recorded when the related revenue from customers is realized. Rebate and promotion accruals are based on estimates of the quantity of customer sales. In prior years, these costs were recognized at the time of coupon issuance. Promotion accruals also consider estimates of the number of consumer coupons that will be redeemed and timing and costs of activities within the promotional programs. Advertising Expense Advertising costs are expensed in the year the related advertisement or campaign is first presented by the media. For interim reporting purposes, advertising expenses are charged to operations as a percentage of sales based on estimated sales and related advertising expense for the full year. Research Expense Research and development costs are charged to expense as incurred. Foreign Currency Translation The income statements of foreign operations, other than those in highly inflationary economies, are translated into U.S. dollars at rates of exchange in effect each month. The balance sheets of these operations are translated at period-end exchange rates, and the differences from historical exchange rates are reflected in stockholders' equity as unrealized translation adjustments. Accounting for Venezuelan Operations Effective December 31, 2015, we deconsolidated the assets and liabilities of our business in Venezuela from our consolidated balance sheet. Other income of $11 was recognized in 2016 related to the shut down of operations in that country and the finalization of the write-off of our investment in K-C Venezuela. Adoption of Highly Inflationary Accounting in Argentina GAAP guidance requires the use of highly inflationary accounting for countries whose cumulative three-year inflation exceeds 100 percent. In the second quarter of 2018, published inflation indices indicated that the three-year cumulative inflation in Argentina exceeded 100 percent, and as of July 1, 2018, we elected to adopt highly inflationary accounting for our subsidiaries in Argentina (“K-C Argentina”). Under highly inflationary accounting, K-C Argentina’s functional currency became the U.S. dollar, and its income statement and balance sheet have been measured in U.S. dollars using both current and historical rates of exchange. The effect of changes in exchange rates on peso-denominated monetary assets and liabilities has been reflected in earnings in Other (income) and expense, net and was not material. As of December 31, 2018, K-C Argentina had a small net peso monetary position. Net sales of K-C Argentina were less than 2 percent of our consolidated net sales in 2018, 2017 and 2016. Derivative Instruments and Hedging Our policies allow the use of derivatives for risk management purposes and prohibit their use for speculation. Our policies also prohibit the use of any leveraged derivative instrument. Consistent with our policies, foreign currency derivative instruments, interest rate swaps and locks, and the majority of commodity hedging contracts are entered into with major financial institutions. At inception, we formally designate certain derivatives as cash flow, fair value or net investment hedges and establish how the effectiveness of these hedges will be assessed and measured. This process links the derivatives to the transactions or financial balances they are hedging. Changes in the fair value of derivatives not designated as hedging instruments are recorded in earnings as they occur. All derivative instruments are recorded as assets or liabilities on the balance sheet at fair value. Changes in the fair value of derivatives are either recorded in the income statement or other comprehensive income, as appropriate. The gain or loss on derivatives designated as fair value hedges and the offsetting loss or gain on the hedged item attributable to the hedged risk are included in income in the period that changes in fair value occur. The gain or loss on derivatives designated as cash flow hedges is included in other comprehensive income in the period that changes in fair value occur, and is reclassified to income in the same period that the hedged item affects income. The gain or loss on derivatives designated as hedges of investments in foreign subsidiaries is recognized in other comprehensive income to offset the change in value of the net investments being hedged. Certain foreign-currency derivative instruments not designated as hedging instruments have been entered into to manage certain non-functional currency denominated monetary assets and liabilities. The gain or loss on these derivatives is included in income in the period that changes in their fair values occur. Cash flows from derivatives are classified within the consolidated statement of cash flows in the same category as the items being hedged. Cash flows from derivatives are classified within Operating Activities, except for derivatives designated as net investment hedges which are classified in Investing Activities. See Note 11 for disclosures about derivative instruments and hedging activities. Accounting Standards - Adopted During 2018 In 2018, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20). The new guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. For public companies, the amendments in this ASU are effective for fiscal years beginning after December 15, 2020, with early adoption permitted. We early adopted this ASU as of December 31, 2018, and applied it on a retrospective basis to all periods presented. In 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This new standard permits entities to reclassify to retained earnings the tax effects stranded in accumulated other comprehensive income ("AOCI") as a result of U.S. tax reform. We early adopted this ASU as of April 1, 2018 and reclassified $156 of stranded tax effects related to the U.S. tax reform change in the federal corporate tax rate from AOCI to retained earnings. This reclassification is included in Other in our consolidated statement of stockholders' equity. In 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The standard requires that an employer report the service cost component in the same line 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 of operating profit (presented as Nonoperating expense in our consolidated income statement). We adopted this standard as of January 1, 2018 and applied the amendments retrospectively, and all applicable amounts included in this filing have been recast accordingly. We used the practical expedient that allowed us to use the amounts previously disclosed in our employee postretirement benefits note for the prior comparative periods as the basis for applying the retrospective presentation requirements. In 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which removes the prohibition against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. We adopted this standard as of January 1, 2018 on a modified retrospective basis and recorded an immaterial cumulative adjustment to retained earnings. In 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. We adopted this ASU effective January 1, 2018 on a full retrospective basis. Adoption of this standard did not result in significant changes to our accounting policies, business processes, systems or controls, or have a material impact on our financial position, results of operations and cash flows or related disclosures. As such, prior period financial statements were not recast. Accounting Standards Issued - Not Adopted as of December 31, 2018 In 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), amended by ASU 2018-11, Leases (Topic 842): Targeted Improvements. Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than 12 months, along with additional disclosures. Current GAAP recognizes, measures and presents expenses and cash flows arising from a lease by a lessee primarily depending on its classification as a finance or operating lease. The ASU requires adoption using a modified retrospective transition approach with either 1) periods prior to the adoption date being recast or 2) a cumulative-effect adjustment recognized to the opening balance of retained earnings on the adoption date with prior periods not recast. We adopted this standard on January 1, 2019 using the cumulative-effect adjustment method and elected certain practical expedients allowed under the standard. No cumulative-effect adjustment was recognized as the amount was not material. We implemented processes and a lease accounting system to ensure adequate internal controls were in place to assess our contracts and enable proper accounting and reporting of financial information upon adoption. The increase in total assets and total liabilities was approximately $0.5 billion. The impact on our results of operations and cash flows was not material. In 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new standard makes more financial and non-financial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess hedge effectiveness. For public companies, the amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This ASU requires adoption using a modified retrospective transition approach with a cumulative-effect adjustment recognized to the opening balance of retained earnings on the adoption date with prior periods not recast. We adopted this standard on January 1, 2019 with no cumulative-effect adjustment as the amount was not material. The effects of this standard on our financial position, results of operations and cash flows were not material. In 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820). The new guidance modifies disclosure requirements related to fair value measurement. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date. In 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40). The new guidance reduces complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). For public companies, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Implementation should be applied either retrospectively or prospectively to all implementation cost incurred after the date of adoption. The effects of this standard on our financial position, results of operations or cash flows are not expected to be material.

Accounting Policies

Basis of Presentation

The consolidated financial statements present the accounts of Kimberly-Clark Corporation and all subsidiaries in which it has a controlling financial interest as if they were a single economic entity in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions and accounts are eliminated in consolidation. The terms "Corporation," "Kimberly-Clark," "we," "our," and "us" refer to Kimberly-Clark Corporation and all subsidiaries in which it has a controlling financial interest. Dollar amounts are reported in millions, except per share dollar amounts, unless otherwise noted.

In prior years, we followed an accounting practice whereby costs associated with sales of K-C Professional dispensers were classified as a reduction in revenue, similar to sales incentives. Effective January 1, 2018, we changed this practice and now classify these costs as cost of products sold. This change resulted in an immaterial increase in net sales and cost of products sold and all applicable prior period amounts included in this filing have been recast accordingly.

Subsequent to the issuance of the December 31, 2017 financial statements, we identified an error in the recording of treasury stock retirements and disbursement transactions. We have assessed these errors and determined they are immaterial as the correction does not result in any change to total stockholders’ equity or in the number of treasury shares reported and does not impact the consolidated statements of income, comprehensive income or cash flow for any period presented. The correction of the cumulative error has been recorded as an adjustment to December 31, 2015 retained earnings, treasury stock and additional paid in capital in the amounts of $960, $968 and $8, respectively, and the prior period financial statements have been revised to reflect the correct amounts.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Actual results could differ from these estimates, and changes in these estimates are recorded when known. Estimates are used in accounting for, among other things, sales incentives and trade promotion allowances, employee postretirement benefits, and deferred income taxes and potential assessments.

Cash Equivalents

Cash equivalents are short-term investments with an original maturity date of three months or less.

Inventories and Distribution Costs

Most U.S. inventories are valued at the lower of cost, using the Last-In, First-Out ("LIFO") method, or market. The balance of the U.S. inventories and inventories of consolidated operations outside the U.S. are valued at the lower of cost or net realizable value using either the First-In, First-Out ("FIFO") or weighted-average cost methods. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Distribution costs are classified as cost of products sold.

Property and Depreciation

Property, plant and equipment are stated at cost and are depreciated on the straight-line method. Buildings are depreciated over their estimated useful lives, primarily 40 years. Machinery and equipment are depreciated over their estimated useful lives, primarily ranging from 16 to 20 years. Purchases of computer software, including external costs and certain internal costs (including payroll and payroll-related costs of employees) directly associated with developing significant computer software applications for internal use, are capitalized. Computer software costs are amortized on the straight-line method over the estimated useful life of the software, which generally does not exceed 5 years.

Estimated useful lives are periodically reviewed and, when warranted, changes are made to them. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. An impairment loss would be indicated when estimated undiscounted future cash flows from the use and eventual disposition of an asset group, which are identifiable and largely independent of the cash flows of other asset groups, are less than the carrying amount of the asset group. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset group over its fair value. Fair value is measured using discounted cash flows or independent appraisals, as appropriate. When property is sold or retired, the cost of the property and the related accumulated depreciation are removed from the consolidated balance sheet and any gain or loss on the transaction is included in income.

Goodwill and Other Intangible Assets

Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not amortized, but rather is assessed for impairment annually and whenever events and circumstances indicate that impairment may have occurred. Impairment testing compares the reporting unit carrying amount, including goodwill, with its fair value. If the reporting unit carrying amount, including goodwill, exceeds its fair value, a goodwill impairment charge for the excess amount above fair value would be recorded. In our evaluation of goodwill impairment, we have the option to first assess qualitative factors such as macroeconomic, industry and competitive conditions, legal and regulatory environments, historical and projected financial performance, significant changes in the reporting unit and the magnitude of excess fair value over carrying amount from the previous quantitative impairment testing. If the qualitative assessment determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then a quantitative impairment test using discounted cash flows to estimate fair value must be performed. On the other hand, if the qualitative assessment determines that it is more likely than not that the fair value of a reporting unit is more than its carrying value, then further quantitative testing is not required. For 2018, we completed the required annual assessment of goodwill for impairment for all of our reporting units using a qualitative assessment as of the first day of the third quarter, and determined that it is more likely than not that the fair value is more than the carrying amount for each of our reporting units.

Intangible assets with finite lives are amortized over their estimated useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. An impairment loss would be indicated when estimated undiscounted future cash flows from the use of the asset are less than its carrying amount. An impairment loss would be measured as the difference between the fair value (based on discounted future cash flows) and the carrying amount of the asset. Estimated useful lives range from 2 to 20 years for trademarks and 5 to 15 years for patents, developed technologies and other intangible assets.

Investments in Equity Companies

Investments in companies which we do not control but over which we have the ability to exercise significant influence and that, in general, are at least 20 percent-owned by us, are stated at cost plus equity in undistributed net income. These investments are evaluated for impairment when warranted. An impairment loss would be recorded whenever a decline in value of an equity investment below its carrying amount is determined to be other than temporary. In judging "other than temporary," we would consider the length of time and extent to which the fair value of the equity company investment has been less than the carrying amount, the near-term and longer-term operating and financial prospects of the equity company, and our longer-term intent of retaining the investment in the equity company.

Revenue Recognition

Sales revenue is recognized at the time of product shipment or delivery, depending on when control passes, to unaffiliated customers, and when all of the following have occurred: a firm sales agreement is in place, pricing is fixed or determinable, and collection is reasonably assured. Sales are reported net of returns, consumer and trade promotions, rebates and freight allowed. Taxes imposed by governmental authorities on our revenue-producing activities with customers, such as sales taxes and value-added taxes, are excluded from net sales.

Sales Incentives and Trade Promotion Allowances

The cost of promotion activities provided to customers is classified as a reduction in sales revenue. In addition, effective January 1, 2018 for interim reporting, the estimated redemption value of consumer coupons and related expense are recorded when the related revenue from customers is realized. Rebate and promotion accruals are based on estimates of the quantity of customer sales. In prior years, these costs were recognized at the time of coupon issuance. Promotion accruals also consider estimates of the number of consumer coupons that will be redeemed and timing and costs of activities within the promotional programs.

Advertising Expense

Advertising costs are expensed in the year the related advertisement or campaign is first presented by the media. For interim reporting purposes, advertising expenses are charged to operations as a percentage of sales based on estimated sales and related advertising expense for the full year.

Research Expense

Research and development costs are charged to expense as incurred.

Foreign Currency Translation

The income statements of foreign operations, other than those in highly inflationary economies, are translated into U.S. dollars at rates of exchange in effect each month. The balance sheets of these operations are translated at period-end exchange rates, and the differences from historical exchange rates are reflected in stockholders' equity as unrealized translation adjustments.

Accounting for Venezuelan Operations

Effective December 31, 2015, we deconsolidated the assets and liabilities of our business in Venezuela from our consolidated balance sheet. Other income of $11 was recognized in 2016 related to the shut down of operations in that country and the finalization of the write-off of our investment in K-C Venezuela.

Adoption of Highly Inflationary Accounting in Argentina

GAAP guidance requires the use of highly inflationary accounting for countries whose cumulative three-year inflation exceeds 100 percent. In the second quarter of 2018, published inflation indices indicated that the three-year cumulative inflation in Argentina exceeded 100 percent, and as of July 1, 2018, we elected to adopt highly inflationary accounting for our subsidiaries in Argentina (“K-C Argentina”). Under highly inflationary accounting, K-C Argentina’s functional currency became the U.S. dollar, and its income statement and balance sheet have been measured in U.S. dollars using both current and historical rates of exchange. The effect of changes in exchange rates on peso-denominated monetary assets and liabilities has been reflected in earnings in Other (income) and expense, net and was not material. As of December 31, 2018, K-C Argentina had a small net peso monetary position. Net sales of K-C Argentina were less than 2 percent of our consolidated net sales in 2018, 2017 and 2016.

Derivative Instruments and Hedging

Our policies allow the use of derivatives for risk management purposes and prohibit their use for speculation. Our policies also prohibit the use of any leveraged derivative instrument. Consistent with our policies, foreign currency derivative instruments, interest rate swaps and locks, and the majority of commodity hedging contracts are entered into with major financial institutions.

The gain or loss on derivatives designated as fair value hedges and the offsetting loss or gain on the hedged item attributable to the hedged risk are included in income in the period that changes in fair value occur. The gain or loss on derivatives designated as cash flow hedges is included in other comprehensive income in the period that changes in fair value occur, and is reclassified to income in the same period that the hedged item affects income.

See Note 11 for disclosures about derivative instruments and hedging activities.

Accounting Standards - Adopted During 2018

In 2018, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20). The new guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. For public companies, the amendments in this ASU are effective for fiscal years beginning after December 15, 2020, with early adoption permitted. We early adopted this ASU as of December 31, 2018, and applied it on a retrospective basis to all periods presented.

In 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This new standard permits entities to reclassify to retained earnings the tax effects stranded in accumulated other comprehensive income ("AOCI") as a result of U.S. tax reform. We early adopted this ASU as of April 1, 2018 and reclassified $156 of stranded tax effects related to the U.S. tax reform change in the federal corporate tax rate from AOCI to retained earnings. This reclassification is included in Other in our consolidated statement of stockholders' equity.

In 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The standard requires that an employer report the service cost component in the same line 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 of operating profit (presented as Nonoperating expense in our consolidated income statement). We adopted this standard as of January 1, 2018 and applied the amendments retrospectively, and all applicable amounts included in this filing have been recast accordingly. We used the practical expedient that allowed us to use the amounts previously disclosed in our employee postretirement benefits note for the prior comparative periods as the basis for applying the retrospective presentation requirements.

In 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which removes the prohibition against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. We adopted this standard as of January 1, 2018 on a modified retrospective basis and recorded an immaterial cumulative adjustment to retained earnings.

In 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. We adopted this ASU effective January 1, 2018 on a full retrospective basis. Adoption of this standard did not result in significant changes to our accounting policies, business processes, systems or controls, or have a material impact on our financial position, results of operations and cash flows or related disclosures. As such, prior period financial statements were not recast.

Accounting Standards Issued - Not Adopted as of December 31, 2018

In 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), amended by ASU 2018-11, Leases (Topic 842): Targeted Improvements. Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than 12 months, along with additional disclosures. Current GAAP recognizes, measures and presents expenses and cash flows arising from a lease by a lessee primarily depending on its classification as a finance or operating lease. The ASU requires adoption using a modified retrospective transition approach with either 1) periods prior to the adoption date being recast or 2) a cumulative-effect adjustment recognized to the opening balance of retained earnings on the adoption date with prior periods not recast. We adopted this standard on January 1, 2019 using the cumulative-effect adjustment method and elected certain practical expedients allowed under the standard. No cumulative-effect adjustment was recognized as the amount was not material. We implemented processes and a lease accounting system to ensure adequate internal controls were in place to assess our contracts and enable proper accounting and reporting of financial information upon adoption. The increase in total assets and total liabilities was approximately $0.5 billion. The impact on our results of operations and cash flows was not material.

In 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new standard makes more financial and non-financial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess hedge effectiveness. For public companies, the amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This ASU requires adoption using a modified retrospective transition approach with a cumulative-effect adjustment recognized to the opening balance of retained earnings on the adoption date with prior periods not recast. We adopted this standard on January 1, 2019 with no cumulative-effect adjustment as the amount was not material. The effects of this standard on our financial position, results of operations and cash flows were not material.

In 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820). The new guidance modifies disclosure requirements related to fair value measurement. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date.

In 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40). The new guidance reduces complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). For public companies, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Implementation should be applied either retrospectively or prospectively to all implementation cost incurred after the date of adoption. The effects of this standard on our financial position, results of operations or cash flows are not expected to be material.
