Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	Basis of Presentation and Accounting Policies In the opinion of management of Rockwell Automation, Inc. ("Rockwell Automation" or "the Company"), the unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly the financial position, results of operations and cash flows for the periods presented and, except as otherwise indicated, such adjustments consist only of those of a normal, recurring nature. These statements should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2019 . The results of operations for the three and nine months ended June 30, 2020 , are not necessarily indicative of the results for the full year. All date references to years and quarters herein refer to our fiscal year and fiscal quarter unless otherwise stated. Receivables Receivables are stated net of an allowance for doubtful accounts of $21.7 million at June 30, 2020 , and $17.4 million at September 30, 2019 . In addition, receivables are stated net of an allowance for certain customer returns, rebates and incentives of $13.9 million at June 30, 2020 , and $12.4 million at September 30, 2019 . Earnings Per Share The following table reconciles basic and diluted earnings per share (EPS) amounts (in millions, except per share amounts): Three Months Ended Nine Months Ended 2020 2019 2020 2019 Net income attributable to Rockwell Automation $ 317.8 $ 261.4 $ 760.7 $ 687.7 Less: Allocation to participating securities (0.3 ) (0.3 ) (0.7 ) (0.7 ) Net income available to common shareowners $ 317.5 $ 261.1 $ 760.0 $ 687.0 Basic weighted average outstanding shares 115.7 117.6 115.8 119.0 Effect of dilutive securities Stock options 0.6 1.0 0.7 0.9 Performance shares 0.1 — — 0.1 Diluted weighted average outstanding shares 116.4 118.6 116.5 120.0 Earnings per share: Basic $ 2.74 $ 2.22 $ 6.56 $ 5.77 Diluted $ 2.73 $ 2.20 $ 6.52 $ 5.73 For the three and nine months ended June 30, 2020 , there were 1.4 million and 1.5 million shares, respectively, related to share-based compensation awards that were excluded from the diluted EPS calculation because they were antidilutive. For each of the three and nine months ended June 30, 2019 , 1.8 million shares related to share-based compensation awards were excluded from the diluted EPS calculation because they were antidilutive. Non-Cash Investing and Financing Activities Capital expenditures of $10.4 million and $12.4 million were accrued within accounts payable and other current liabilities at June 30, 2020 and 2019 , respectively. At June 30, 2019 , there was $6.0 million of outstanding common stock share repurchases recorded in accounts payable that did not settle until the next fiscal quarter. At June 30, 2020 , there were no outstanding common stock share repurchases. These non-cash investing and financing activities have been excluded from cash used for capital expenditures and treasury stock purchases in the Consolidated Statement of Cash Flows. Leases We have operating leases primarily for real estate, vehicles, and equipment. We determine if a contract is, or contains, a lease at contract inception. A right-of-use (ROU) asset and a corresponding lease liability are recognized at commencement for contracts that are, or contain, a lease with an original term greater than 12 months. ROU assets represent our right to use an underlying asset during the lease term, including periods for which renewal options are reasonably certain to be exercised, and lease liabilities represent our obligation to make lease payments arising from the lease. Lease expense is recognized on a straight-line basis over the lease term for operating leases with an original term of 12 months or less. Some leasing arrangements require variable payments that are dependent on usage or may vary for other reasons, such as payments for insurance and tax payments. A portion of our real estate leases is generally subject to annual changes based upon an index. The changes based upon the index are treated as variable lease payments. The variable portion of lease payments is not included in our ROU assets or lease liabilities and is expensed when incurred. We elected to not separate lease and nonlease components of contracts for all underlying asset classes. Accordingly, all expenses associated with a lease contract are accounted for as lease expenses. Lease liabilities are recognized at the contract commencement date based on the present value of remaining lease payments over the lease term. To calculate the lease liabilities we use our incremental borrowing rate. We determine our incremental borrowing rate at the commencement date using our unsecured borrowing rate, adjusted for collateralization and lease term. For leases denominated in a currency other than the U.S. dollar, the collateralized borrowing rate in the foreign currency is determined using the U.S. dollar and foreign currency swap spread. Long-term lease liabilities are presented as operating lease liabilities and current lease liabilities are included in other current liabilities in the Consolidated Balance Sheet. ROU assets are recognized at the contract commencement date at the value of the related lease liability, adjusted for any prepayments, lease incentives received and initial direct costs incurred. Operating lease ROU assets are presented as operating lease right-of-use assets in the Consolidated Balance Sheet. Lease expenses for operating leases are recognized on a straight-line basis over the lease term and recorded in Cost of sales and Selling, general and administrative expenses in the Consolidated Statement of Operations. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued a new standard on accounting for leases that requires lessees to recognize right-of-use assets and lease liabilities for most leases, among other changes to existing lease accounting guidance. The new standard also requires additional qualitative and quantitative disclosures about leasing activities. We adopted the new standard using the modified retrospective transition method, which resulted in an immaterial cumulative-effect adjustment to the opening balance of retained earnings as of October 1, 2019, our adoption date. The amount of lease right-of-use assets and corresponding lease liabilities recorded in the Consolidated Balance Sheet upon adoption were $316 million and $329 million , respectively. We have implemented necessary changes to accounting policies, processes, controls and systems to enable compliance with this new standard. In February 2018, the FASB issued a new standard regarding the reporting of comprehensive loss, which gives entities the option to reclassify tax effects of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) stranded in accumulated other comprehensive loss into retained earnings. We adopted the new standard as of October 1, 2019, and elected to reclassify tax effects of $146.8 million from accumulated other comprehensive loss into retained earnings.

Revenue Recognition

Revenue Recognition	9 Months Ended
	Jun. 30, 2020
Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Unfulfilled Performance Obligations As of June 30, 2020 , we expect to recognize approximately $480 million of revenue in future periods from unfulfilled performance obligations from existing contracts with customers. We expect to recognize revenue of approximately $320 million from our remaining performance obligations over the next 12 months with the remaining balance recognized thereafter. We have applied the practical expedient to exclude the value of remaining performance obligations for (i) contracts with an original term of one year or less and (ii) contracts for which we recognize revenue in proportion to the amount we have the right to invoice for services performed. The amounts above also do not include the impact of contract renewal options that are unexercised as of June 30, 2020 .

Business Combinations [Abstract]
Acquisitions	Acquisitions Sensia joint venture On October 1, 2019, we completed the formation of a joint venture, Sensia, a fully integrated digital oilfield automation solutions provider. Rockwell Automation owns 53% of Sensia and Schlumberger owns 47% of Sensia. As part of the transaction, we made $247.0 million of net cash payments to Schlumberger, which were funded by cash on hand. We control Sensia and, as of October 1, 2019, have consolidated Sensia in our financial results. Rockwell Automation recorded assets acquired and liabilities assumed in connection with the formation of Sensia based on their estimated fair values as of the October 1, 2019, acquisition date. The preliminary purchase price allocation is as follows (in millions): Purchase Price Allocation Accounts receivable $ 22.0 Inventory 61.1 Other current assets 1.2 Property, plant and equipment 9.3 Other assets 6.2 Goodwill 307.5 Intangible assets 254.1 Total assets acquired 661.4 Less: Liabilities assumed (37.0 ) Less: Deferred income taxes (2.7 ) Less: Noncontrolling interest portion (293.8 ) Net assets acquired $ 327.9 Purchase Consideration Cash, net of cash acquired $ 247.0 Noncontrolling interest portion of Rockwell Automation's contributed business 26.6 Additional paid in capital adjustment 47.3 Other 7.0 Total purchase consideration, net of cash acquired $ 327.9 Intangible assets assigned include $254.1 million of customer relationships, technology, and trade names (approximately 11 -year weighted average useful life). We assigned the full amount of goodwill and all other assets acquired to our Control Products & Solutions segment. The majority of the goodwill recorded is expected to be deductible for tax purposes. The assets were valued using an income approach, specifically the relief from royalty method and multi-period excess earnings method. The relief from royalty method calculates value based on hypothetical payments that would be saved by owning an asset rather than licensing it. The multi-period excess earnings method is the isolation of cash flows from a single intangible asset and measures fair value by discounting them to present value. These values are considered level 3 measurements under accounting principles generally accepted in the United States (U.S. GAAP) fair value hierarchy. Key assumptions used in the valuation of these intangible assets included: (1) a discount rate of 11% , (2) the estimated remaining life of technology and trademarks of from 5 to 15 years , and (3) the customer attrition rate ranging from 7.5% to 25% . The fair value of the noncontrolling interest of the contributed business upon acquisition was $293.8 million . The consolidated value of Sensia is recorded at fair value for Schlumberger's contribution and at carrying value for Rockwell Automation's contribution. The total incremental sales resulting from the Sensia joint venture included in our consolidated results for the three and nine months ended June 30, 2020, were approximately $37.8 million and $160.8 million , respectively. Other acquisitions In October 2019, we acquired MESTECH Services (MESTECH), a global provider of Manufacturing Execution Systems / Manufacturing Operations Management, digital solutions consulting, and systems integration services. We assigned the full amount of goodwill related to this acquisition to our Control Products & Solutions segment. In January 2020, we acquired Avnet Data Security, LTD (Avnet), an Israel-based cybersecurity provider with over 20 years of experience providing cybersecurity services. We assigned the full amount of goodwill related to this acquisition to our Control Products & Solutions segment. In April 2020, we acquired ASEM, S.p.A. (ASEM), a leading provider of digital automation technologies. We assigned the full amount of goodwill related to this acquisition to our Architecture & Software segment in the Consolidated Financial Statements. In April 2020, we also acquired Kalypso, LP (Kalypso), a privately-held US-based software delivery and consulting firm specializing in the digital transformation of industrial companies with a strong client base in life sciences, consumer products and industrial high-tech. We assigned the full amount of goodwill related to this acquisition to our Control Products & Solutions segment. Rockwell Automation recorded assets acquired and liabilities assumed in connection with these acquisitions based on their estimated fair values as of the respective acquisition dates. The preliminary aggregate purchase price allocation is as follows (in millions): Purchase Price Allocation Accounts receivable $ 32.7 Inventory 9.6 Other current assets 1.1 Property, plant and equipment 6.0 Other assets 2.3 Goodwill 244.4 Intangible assets 76.5 Total assets acquired 372.6 Less: Liabilities assumed (29.2 ) Less: Deferred income taxes (14.4 ) Net assets acquired $ 329.0 Purchase Consideration Total purchase consideration, net of cash acquired $ 329.0 Intangible assets assigned include $76.5 million of customer relationships, technology, and trade names (approximately 10 -year weighted average useful life). We assigned $161.3 million of goodwill to our Architecture & Software segment and $83.1 million of goodwill to our Control Products & Solutions segment. Approximately $68.9 million of the goodwill recorded is expected to be deductible for tax purposes. The purchase consideration includes $25.8 million of contingent consideration held in an escrow account and recorded in cash and cash equivalents in the Consolidated Balance Sheet. The total sales included in our consolidated results from these four acquisitions for the three and nine months ended June 30, 2020, were approximately $15.5 million and $18.6 million , respectively. The allocation of the purchase price to identifiable assets for all of the preceding acquisitions are based on the preliminary valuations performed to determine the fair value of the net assets as of the acquisition date. The measurement period for the valuation of net assets acquired ends as soon as information on the facts and circumstances that existed as of the acquisition dates becomes available, but not to exceed 12 months following the acquisition date. Adjustments in purchase price allocations may require a change in the amounts allocated to net assets acquired during the periods in which the adjustments are determined. Pro forma consolidated sales for the three and nine months ended June 30, 2019, are approximately $1.8 billion and $5.2 billion , respectively, and the impact on earnings is not material. The preceding pro forma consolidated financial results of operations are as if all of the preceding acquisitions occurred on October 1, 2018. The pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved had the transaction occurred as of that time. Acquisition-related costs recorded as expenses for all of the preceding acquisitions in the three and nine months ended June 30, 2020, were not material.

We perform our annual evaluation of goodwill and indefinite life intangible assets for impairment as required by U.S. GAAP at the beginning of the second quarter of each year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. For our annual evaluation of goodwill, we may perform a qualitative test to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in order to determine whether it is necessary to perform a quantitative goodwill impairment test. When performing the quantitative goodwill impairment test, we determine the fair value of each reporting unit under a combination of an income approach derived from discounted cash flows and a market multiples approach using selected comparable public companies. Significant assumptions used in the income approach include: management’s forecasted cash flows, including estimated future revenue growth rates and margins, discount rate, and terminal value. Forecasted future revenue growth and margins are based on management’s best estimate about current and future conditions. Discount rates are determined using weighted average cost of capital adjusted for risk factors specific to the reporting unit level, with comparison to market and industry data. The terminal value is estimated following common methodology of calculating the present value of estimated perpetual cash flow beyond the last projected period assuming constant discount and long-term growth rates. Significant assumptions used in the market multiples approach include selection of the comparable public companies and calculation of the appropriate market multiples. For our 2020 annual evaluation, we performed a qualitative test for our Architecture & Software reporting unit and our Control Products & Solutions (excluding Sensia) reporting unit. We performed a quantitative test for our Sensia reporting unit. Based on those evaluations, we concluded these assets were no t impaired. We also assessed the changes in events and circumstances subsequent to our annual test, including those related to the COVID-19 pandemic and conditions within the Oil & Gas industry, and concluded that a triggering event which would require interim testing has not occurred.

The short-term loans from Schlumberger were entered into following formation of Sensia. See Note 5 in the Consolidated Financial Statements for additional information on Sensia. In March 2020, we repaid our $300.0 million 2.050% notes which were classified as the current portion of long-term debt at September 30, 2019 . In April 2020, we entered into a $400.0 million senior unsecured 364-day term loan credit agreement and were advanced the full loan amount. This agreement is in addition to our existing $1.25 billion unsecured revolving credit facility expiring in November 2023, which remains available and undrawn. Borrowings under this term loan bear interest based on short-term money market rates in effect during the period the borrowings are outstanding. The term loan agreement contains covenants similar to those under our $1.25 billion unsecured revolving credit facility, under which we agree to maintain an EBITDA-to-interest ratio of at least 3.0 to 1.0. The EBITDA-to-interest ratio is defined in the term loan agreement as the ratio of consolidated EBITDA (as defined in the term loan agreement) for the preceding four quarters to consolidated interest expense for the same period. In May 2020, we settled the interest swaps that were designated as a fair value hedge of our 2.875% notes payable in March 2025 ("2025 Notes") and received $22.0 million from the counterparties. The $22.0 million gain on the settlement of the interest rate swaps was recorded as an adjustment to the carrying value of the 2025 Notes and is being amortized over the remaining term of those notes as an adjustment to interest expense in the Consolidated Statement of Operations.

Equity Securities On July 19, 2018, we purchased 10,582,010 shares of PTC Inc. ("PTC") common stock (the "PTC Shares") in a private placement at a purchase price of $94.50 per share for an aggregate purchase price of approximately $1.0 billion (the "Purchase"). The PTC Shares are considered equity securities. For a period of approximately 3 years after the Purchase, we are subject to entity-specific transfer restrictions subject to certain exceptions. Since the first anniversary of the Purchase, the Company has had the ability to transfer, in the aggregate in any 90 -day period, a number of PTC Shares equal to up to 1.0% of PTC's total outstanding shares of common stock as of the first day in such 90 -day period, but no more than 2.0% of PTC's total outstanding shares of common stock in each of the second year and the third year after the Purchase. Fair Value of Investments U.S. GAAP defines fair value as the price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. U.S. GAAP also classifies the inputs used to measure fair value into the following hierarchy: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability. Level 3: Unobservable inputs for the asset or liability. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our 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. We did not have any transfers between levels of fair value measurements during the period presented. The PTC Shares are classified as level 1 in the fair value hierarchy and recognized at fair value in the Consolidated Balance Sheet using the most recent closing price of PTC common stock quoted on Nasdaq. At June 30, 2020 , the fair value of the PTC Shares was $823.2 million , which was recorded in long-term investments in the Consolidated Balance Sheet. For the three and nine months ended June 30, 2020 , we recorded gains of $175.5 million and $101.7 million related to the PTC Shares, respectively. For the three and nine months ended June 30, 2019, we recorded losses of $25.6 million and $140.1 million related to the PTC Shares, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Various lawsuits, claims and proceedings have been or may be instituted or asserted against us relating to the conduct of our business, including those pertaining to product liability, environmental, safety and health, intellectual property, employment and contract matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, we believe the disposition of matters that are pending or have been asserted will not have a material effect on our business, financial condition or results of operations. The following outlines additional background for obligations associated with asbestos, divested businesses and intellectual property. We (including our subsidiaries) have been named as a defendant in lawsuits alleging personal injury as a result of exposure to asbestos that was used in certain components of our products many years ago, including products from divested businesses for which we have agreed to defend and indemnify claims. Currently there are a few thousand claimants in lawsuits that name us as defendants, together with hundreds of other companies. But in all cases, for those claimants who do show that they worked with our products or products of divested businesses for which we are responsible, we nevertheless believe we have meritorious defenses, in substantial part due to the integrity of the products, the encapsulated nature of any asbestos-containing components, and the lack of any impairing medical condition on the part of many claimants. We defend those cases vigorously. Historically, we have been dismissed from the vast majority of these claims with no payment to claimants. Additionally, we have maintained insurance coverage that includes indemnity and defense costs, over and above self-insured retentions, for many of these claims. We believe these arrangements will provide substantial coverage for future defense and indemnity costs for these asbestos claims throughout the remaining life of asbestos liability. The uncertainties of asbestos claim litigation make it difficult to predict accurately the ultimate outcome of asbestos claims. That uncertainty is increased by the possibility of adverse rulings or new legislation affecting asbestos claim litigation or the settlement process. Subject to these uncertainties and based on our experience defending asbestos claims, we do not believe these lawsuits will have a material effect on our business, financial condition or results of operations. We have, from time to time, divested certain of our businesses. In connection with these divestitures, certain lawsuits, claims and proceedings may be instituted or asserted against us related to the period that we owned the businesses, either because we agreed to retain certain liabilities related to these periods or because such liabilities fall upon us by operation of law. In some instances the divested business has assumed the liabilities; however, it is possible that we might be responsible to satisfy those liabilities if the divested business is unable to do so. We do not believe these liabilities will have a material effect on our business, financial condition or results of operations. In many countries we provide a limited intellectual property indemnity as part of our terms and conditions of sale. We also at times provide limited intellectual property indemnities in other contracts with third parties, such as contracts concerning the development and manufacture of our hardware and software products. As of June 30, 2020 , we were not aware of any material indemnification claims that were probable or reasonably possible of an unfavorable outcome. Historically, claims that have been made under the indemnification agreements have not had a material impact on our business, financial condition or results of operations; however, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our business, financial condition or results of operations in a particular period.

Leases [Abstract]
Leases	Leases We have operating leases primarily for real estate, vehicles and equipment. Our leases have remaining lease terms from less than one year to approximately 14 years . We do not have a material amount of finance leases. We elected the package of practical expedients permitted under the transition guidance within the new standard which allows the Company to carry forward the historical assessments of whether contracts are, or contain, leases, lease classification and initial direct costs. We also elected to not record lease ROU assets or lease liabilities for leases with an original term of 12 months or less. We elected to use the remaining lease term for purposes of calculating the incremental borrowing rate upon transition. The components of lease expense were as follows (in millions): Three Months Ended June 30, 2020 Nine Months Ended June 30, 2020 Operating lease expense (1) $ 25.4 $ 76.4 Variable lease expense (2) 3.5 11.0 Total lease expense $ 28.9 $ 87.4 (1) Operating lease expense includes short-term lease expense which was not material. (2) Variable lease expense includes sublease income which was not material. Supplemental balance sheet information related to leases was as follows (in millions): June 30, 2020 Weighted average remaining lease term 5.8 years Weighted average discount rate 1.98 % Maturities of lease liabilities as of June 30, 2020 , were as follows (in millions): 2020 (excluding the nine months ended June 30, 2020) $ 23.2 2021 93.4 2022 72.0 2023 52.2 2024 36.6 2025 23.0 Thereafter 61.8 Total undiscounted lease payments $ 362.2 Less imputed interest (22.4 ) Total operating lease liabilities $ 339.8 Undiscounted maturities of operating leases accounted for under ASC 840 as of September 30, 2019, were as follows (in millions): 2020 $ 90.6 2021 72.6 2022 51.8 2023 36.7 2024 26.4 Thereafter 63.8 Total minimum lease payments $ 341.9 Supplemental cash flow information related to leases was as follows (in millions): Nine Months Ended June 30, 2020 Cash paid for amounts included in the measurement of operating lease liabilities $ 75.2 Operating right-of-use assets obtained in exchange for lease obligations 81.4

Income Taxes

Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim period, we estimate a base effective tax rate that we expect for the full fiscal year based on our most recent forecast of pre-tax income, permanent book and tax differences and global tax planning strategies. We use this base rate to provide for income taxes on a year-to-date basis, excluding the effect of significant unusual items and items that are reported net of their related tax effects in the period in which they occur. The effective tax rate was 6.1 percent and 9.2 percent in the three and nine months ended June 30, 2020 , respectively, compared to 18.7 percent and 18.6 percent in the three and nine months ended June 30, 2019 . The effective tax rate was lower than the U.S. statutory rate of 21 percent in the three months ended June 30, 2020 , primarily due to PTC investment adjustments and other favorable discrete tax items. The effective tax rate was lower than the U.S. statutory rate of 21 percent in the nine months ended June 30, 2020 , primarily due to PTC investment adjustments and other tax benefits recognizable upon the formation of the Sensia joint venture, excess income tax benefits of share-based compensation, and other favorable discrete tax items. The effective tax rate was lower than the U.S. statutory rate of 21 percent in the three months ended June 30, 2019 , primarily because we benefited from lower non-U.S. tax rates. The effective rate was lower than the U.S. statutory rate of 21 percent in the nine months ended June 30, 2019 primarily because we benefited from lower non-U.S. tax rates. Income tax liabilities of $296.0 million and $327.2 million related to the U.S. transition tax under the Tax Act that are payable greater than 12 months from June 30, 2020 , and September 30, 2019 , respectively, are recorded in other liabilities in the Consolidated Balance Sheet. We operate in certain non-U.S. tax jurisdictions under government-sponsored tax incentive programs, which may be extended if certain additional requirements are met. The program which generates the primary benefit will expire in 2032. Unrecognized Tax Benefits The amount of gross unrecognized tax benefits was $25.6 million and $19.9 million at June 30, 2020 and September 30, 2019 , respectively, of which the entire amount would reduce our effective tax rate if recognized. Accrued interest and penalties related to unrecognized tax benefits were $3.9 million and $3.3 million at June 30, 2020 , and September 30, 2019 , respectively. We recognize interest and penalties related to unrecognized tax benefits in the income tax provision. We believe it is reasonably possible that the amount of gross unrecognized tax benefits could be reduced by up to $24.1 million in the next 12 months as a result of the resolution of tax matters in various global jurisdictions and the lapses of statutes of limitations. If all of the unrecognized tax benefits were recognized, the net reduction to our income tax provision, including the recognition of interest and penalties and offsetting tax assets, could be up to $25.8 million . We conduct business globally and are routinely audited by the various tax jurisdictions in which we operate. We are no longer subject to U.S. federal income tax examinations for years before 2016 and are no longer subject to state, local and foreign income tax examinations for years before 2009 .

Depending on the product, intersegment sales within a single legal entity are either at cost or cost plus a mark-up, which does not necessarily represent a market price. Sales between legal entities are at an appropriate transfer price. We allocate costs related to shared segment operating activities to the segments using a methodology consistent with the expected benefit.

Receivables	Receivables
Leases	Leases We have operating leases primarily for real estate, vehicles, and equipment. We determine if a contract is, or contains, a lease at contract inception. A right-of-use (ROU) asset and a corresponding lease liability are recognized at commencement for contracts that are, or contain, a lease with an original term greater than 12 months. ROU assets represent our right to use an underlying asset during the lease term, including periods for which renewal options are reasonably certain to be exercised, and lease liabilities represent our obligation to make lease payments arising from the lease. Lease expense is recognized on a straight-line basis over the lease term for operating leases with an original term of 12 months or less. Some leasing arrangements require variable payments that are dependent on usage or may vary for other reasons, such as payments for insurance and tax payments. A portion of our real estate leases is generally subject to annual changes based upon an index. The changes based upon the index are treated as variable lease payments. The variable portion of lease payments is not included in our ROU assets or lease liabilities and is expensed when incurred. We elected to not separate lease and nonlease components of contracts for all underlying asset classes. Accordingly, all expenses associated with a lease contract are accounted for as lease expenses. Lease liabilities are recognized at the contract commencement date based on the present value of remaining lease payments over the lease term. To calculate the lease liabilities we use our incremental borrowing rate. We determine our incremental borrowing rate at the commencement date using our unsecured borrowing rate, adjusted for collateralization and lease term. For leases denominated in a currency other than the U.S. dollar, the collateralized borrowing rate in the foreign currency is determined using the U.S. dollar and foreign currency swap spread. Long-term lease liabilities are presented as operating lease liabilities and current lease liabilities are included in other current liabilities in the Consolidated Balance Sheet. ROU assets are recognized at the contract commencement date at the value of the related lease liability, adjusted for any prepayments, lease incentives received and initial direct costs incurred. Operating lease ROU assets are presented as operating lease right-of-use assets in the Consolidated Balance Sheet. Lease expenses for operating leases are recognized on a straight-line basis over the lease term and recorded in Cost of sales and Selling, general and administrative expenses in the Consolidated Statement of Operations.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued a new standard on accounting for leases that requires lessees to recognize right-of-use assets and lease liabilities for most leases, among other changes to existing lease accounting guidance. The new standard also requires additional qualitative and quantitative disclosures about leasing activities. We adopted the new standard using the modified retrospective transition method, which resulted in an immaterial cumulative-effect adjustment to the opening balance of retained earnings as of October 1, 2019, our adoption date. The amount of lease right-of-use assets and corresponding lease liabilities recorded in the Consolidated Balance Sheet upon adoption were $316 million and $329 million , respectively. We have implemented necessary changes to accounting policies, processes, controls and systems to enable compliance with this new standard. In February 2018, the FASB issued a new standard regarding the reporting of comprehensive loss, which gives entities the option to reclassify tax effects of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) stranded in accumulated other comprehensive loss into retained earnings. We adopted the new standard as of October 1, 2019, and elected to reclassify tax effects of $146.8 million from accumulated other comprehensive loss into retained earnings.
Goodwill and Intangible Assets, Goodwill, Policy	We perform our annual evaluation of goodwill and indefinite life intangible assets for impairment as required by U.S. GAAP at the beginning of the second quarter of each year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. For our annual evaluation of goodwill, we may perform a qualitative test to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in order to determine whether it is necessary to perform a quantitative goodwill impairment test. When performing the quantitative goodwill impairment test, we determine the fair value of each reporting unit under a combination of an income approach derived from discounted cash flows and a market multiples approach using selected comparable public companies. Significant assumptions used in the income approach include: management’s forecasted cash flows, including estimated future revenue growth rates and margins, discount rate, and terminal value. Forecasted future revenue growth and margins are based on management’s best estimate about current and future conditions. Discount rates are determined using weighted average cost of capital adjusted for risk factors specific to the reporting unit level, with comparison to market and industry data. The terminal value is estimated following common methodology of calculating the present value of estimated perpetual cash flow beyond the last projected period assuming constant discount and long-term growth rates. Significant assumptions used in the market multiples approach include selection of the comparable public companies and calculation of the appropriate market multiples.
