Summary Of Significant Accounti

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Financial Statement Presentation The preparation of the financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect reported amounts and related disclosures. Actual results could differ from these estimates. Certain prior year amounts have been reclassified to conform with current year presentation. On October 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers , which updated and consolidated revenue recognition guidance from multiple sources into a single, comprehensive standard to be applied for all contracts with customers. The fundamental principle of the revised standard is to recognize revenue based on the transfer of goods and services to customers at the amount the Company expects to be entitled to in exchange for those goods and services. The Company adopted the new standard using the modified retrospective approach and applied the guidance to open contracts which were not completed at the date of adoption. The cumulative effect of adoption resulted in a $30 increase to beginning retained earnings as of October 1, 2018. This increase primarily related to contracts where a portion of revenue for delivered goods or services was previously deferred due to contingent payment terms. The adoption of ASC 606 did not materially impact the Company's consolidated financial statements as of and for the year ended September 30, 2019. Amounts reported for the years ended September 30, 2018 and 2017 continue to be reported in accordance with the Company's historic accounting under ASC 605, Revenue Recognition . In the first quarter of fiscal 2019, the Company adopted updates to ASC 715, Compensation - Retirement Benefits , which permit only the service cost component of net periodic pension and postretirement expense to be reported with compensation costs, while all other components are required to be reported separately in other deductions. These updates were adopted retrospectively and resulted in the reclassification of $40 of income and $38 of expense in 2018 and 2017, respectively, from cost of sales and SG&A to other deductions, net. Segment earnings were not impacted by the updates to ASC 715. In the fourth quarter of 2018, the Company adopted updates to ASC 220, Comprehensive Income , which permit reclassification of stranded tax effects resulting from U.S. tax reform from accumulated other comprehensive income to retained earnings. The Company reclassified $100 of stranded tax effects from accumulated other comprehensive income to retained earnings upon adoption of these updates. See Note 17. In the first quarter of 2018, the Company adopted updates to ASC 740, Income Taxes , which require recognition of the income tax effects of intra-entity transfers of assets other than inventory when the transfer occurs, on a modified retrospective basis. The adoption of these updates resulted in an increase of $3 to retained earnings. In the first quarter of 2018, the Company adopted updates to ASC 330, Inventory , which changed the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. These updates were adopted prospectively and did not materially impact the Company's financial statements. In the fourth quarter of 2017, the Company adopted updates to ASC 718, Compensation - Stock Compensation , which require all excess tax benefits and deficiencies related to share-based payments to be recognized in income tax expense rather than through additional paid-in-capital, and to be presented as operating cash flows instead of financing. These updates did not materially impact the Company's financial statements. In the fourth quarter of 2017, the Company adopted updates to ASC 820, Fair Value Measurement , which require investments measured using the net asset value per share practical expedient to be removed from the fair value hierarchy and separately reported when making disclosures. These updates did not change the determination of fair value for any investments. Adoption affected disclosure presentation only; there was no impact on the Company’s financial results. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its controlled affiliates. Intercompany transactions, profits and balances are eliminated in consolidation. Investments of 20 percent to 50 percent of the voting shares of other entities are accounted for by the equity method. Investments in publicly traded companies of less than 20 percent are carried at fair value, with changes in fair value reflected in accumulated other comprehensive income. Investments in nonpublicly traded companies of less than 20 percent are carried at cost, minus impairment, and adjusted for observable price changes in orderly transactions. Foreign Currency Translation The functional currency for most of the Company's non-U.S. subsidiaries is the local currency. Adjustments resulting from translating local currency financial statements into U.S. dollars are reflected in accumulated other comprehensive income. Cash Equivalents Cash equivalents consist of highly liquid investments with original maturities of three months or less. Inventories Inventories are stated at the lower of cost and net realizable value. The majority of inventory is valued based on standard costs, which approximate average costs, while the remainder is principally valued on a first-in, first-out basis. Cost standards are revised at the beginning of each year. The annual effect of resetting standards plus any operating variances incurred during each period are allocated to inventories and recognized in cost of sales as product is sold. Following are the components of inventory as of September 30: 2018 2019 Finished products $ 592 578 Raw materials and work in process 1,221 1,302 Total inventories $ 1,813 1,880 Fair Value Measurement ASC 820, Fair Value Measurement , establishes a formal hierarchy and framework for measuring certain financial statement items at fair value, and requires disclosures about fair value measurements and the reliability of valuation inputs. Under ASC 820, measurement assumes the transaction to sell an asset or transfer a liability occurs in the principal or at least the most advantageous market for that asset or liability. Within the hierarchy, Level 1 instruments use observable market prices for an identical item in active markets and have the most reliable valuations. Level 2 instruments are valued through broker/dealer quotation or other approaches using market-observable inputs for similar items in active markets, including forward and spot prices, interest rates and volatilities. Level 3 instruments are valued using inputs not observable in an active market, such as company-developed future cash flow estimates, and are considered the least reliable. Valuations for all of the Company's financial instruments fall within Level 2. The fair value of the Company's long-term debt is Level 2, estimated using current interest rates and pricing from financial institutions and other market sources for debt with similar maturities and characteristics. Property, Plant and Equipment The Company records investments in land, buildings, and machinery and equipment at cost. Depreciation is computed principally using the straight-line method over estimated service lives, which for principal assets are 30 to 40 years for buildings and 8 to 12 years for machinery and equipment. Long-lived tangible assets are reviewed for impairment whenever events or changes in business circumstances indicate the carrying value of the assets may not be recoverable. Impairment losses are recognized based on estimated fair values if the sum of estimated future undiscounted cash flows of the related assets is less than the carrying values. The components of property, plant and equipment as of September 30 follow: 2018 2019 Land $ 316 336 Buildings 2,145 2,219 Machinery and equipment 5,470 5,645 Construction in progress 439 471 Property, plant and equipment, at cost 8,370 8,671 Less: Accumulated depreciation 4,808 5,029 Property, plant and equipment, net $ 3,562 3,642 Goodwill and Other Intangible Assets Assets and liabilities acquired in business combinations are accounted for using the acquisition method and recorded at their respective fair values. Substantially all goodwill is assigned to the reporting unit that acquires a business. A reporting unit is an operating segment as defined in ASC 280, Segment Reporting , or a business one level below an operating segment if discrete financial information for that business unit is prepared and regularly reviewed by the segment manager. The Company conducts annual impairment tests of goodwill in the fourth quarter. If an initial assessment indicates it is more likely than not goodwill might be impaired, it is evaluated by comparing the reporting unit's estimated fair value to its carrying value. Goodwill is also tested for impairment between annual tests if events or circumstances indicate the fair value of a unit may be less than its carrying value. If the carrying amount exceeds the estimated fair value, impairment is recognized to the extent that recorded goodwill exceeds the implied fair value of that goodwill. Estimated fair values of reporting units are Level 3 measures and are developed generally under an income approach that discounts estimated future cash flows using risk-adjusted interest rates, as well as earnings multiples or other techniques as warranted. Fair values are subject to changes in underlying economic conditions. All of the Company's identifiable intangible assets are subject to amortization on a straight-line basis over their estimated useful lives. Identifiable intangibles consist of intellectual property such as patents and trademarks, customer relationships and capitalized software. Identifiable intangibles are also subject to evaluation for potential impairment if events or circumstances indicate the carrying amount may not be recoverable. See Note 7. Product Warranty Warranties vary by product line and are competitive for the markets in which the Company operates. Warranties are largely offered to provide assurance that the product will function as intended and generally extend for a period of one to two years from the date of sale or installation. Provisions for warranty expense are estimated at the time of sale based on historical experience and adjusted quarterly for any known issues that may arise. Product warranty expense is less than one percent of sales. Revenue Recognition Emerson is a global manufacturer that combines technology and engineering to provide innovative solutions to its customers, largely in the form of tangible products. The Company evaluates its contracts with customers to identify the promised goods or services and recognizes revenue for the identified performance obligations at the amount the Company expects to be entitled to in exchange for those goods or services. A performance obligation is a promise in a contract to transfer a distinct good or service to a customer. Revenue is recognized when, or as, performance obligations are satisfied and control has transferred to the customer, typically when products are shipped or delivered, title and risk of loss pass to the customer, and the Company has a present right to payment. The vast majority of the Company's revenues relate to a broad offering of manufactured products which are recognized at the point in time when control transfers, generally in accordance with shipping terms. A portion of the Company's revenues relate to the sale of software and post-contract customer support, parts and labor for repairs, and engineering services. In limited circumstances, contracts include multiple performance obligations, where revenue is recognized separately for each good or service, as well as contracts where revenue is recognized over time as control transfers to the customer. Revenue is recognized over time for approximately 5 percent of the Company's revenues. These contracts largely relate to projects in the Process Control Systems & Solutions product offering within the Automation Solutions segment where revenue is recognized using the percentage-of-completion method to reflect the transfer of control over time, while a small amount is attributable to long-term maintenance and service contracts where revenue is typically recognized on a straight-line basis as the services are provided. Approximately 5 percent of revenues relate to sales arrangements with multiple performance obligations, principally in the Automation Solutions segment. Tangible products represent a large majority of the delivered items in contracts with multiple performance obligations or where revenue is recognized over time, while a smaller portion is attributable to installation, service and maintenance. For revenues recognized over time, the Company typically uses an input method to determine progress and recognize revenue, based on costs incurred. The Company believes costs incurred closely correspond with its performance under the contract and the transfer of control to the customer. In sales arrangements that involve multiple performance obligations, revenue is allocated based on the relative standalone selling price for each performance obligation. Observable selling prices from actual transactions are used whenever possible. In other instances, the Company determines the standalone selling price based on third-party pricing or management's best estimate. Generally, contract duration is short-term, and cancellation, termination or refund provisions apply only in the event of contract breach and are rarely invoked. Payment terms vary but are generally short-term in nature. The Company's long-term contracts, where revenue is generally recognized over time, are typically billed as work progresses in accordance with the contract terms and conditions, either at periodic intervals or upon achievement of certain milestones. The timing of revenue recognition and billings under these contracts results in either unbilled receivables (contract assets) when revenue recognized exceeds billings, or customer advances (contract liabilities) when billings exceed revenue recognized. Unbilled receivables are reclassified to accounts receivable when an unconditional right to consideration exists, typically when a milestone in the contract is achieved. The Company does not evaluate whether the transaction price includes a significant financing component for contracts where the time between cash collection and performance is less than one year. Certain arrangements with customers include variable consideration, typically in the form of rebates, cash discounts or penalties. In limited circumstances, the Company sells products with a general right of return. In most instances, returns are limited to product quality issues. The Company records a reduction to revenue at the time of sale to reflect the ultimate amount of consideration it expects to receive. The Company's estimates are updated quarterly based on historical experience, trend analysis, and expected market conditions. Variable consideration is typically not constrained at the time revenue is recognized. See Notes 2 and 18 for additional information about the Company's revenues. Derivatives and Hedging In the normal course of business, the Company is exposed to changes in interest rates, foreign currency exchange rates and commodity prices due to its worldwide presence and diverse business profile. The Company's foreign currency exposures relate to transactions denominated in currencies that differ from the functional currencies of its business units, primarily in euros, Mexican pesos and Singapore dollars. Primary commodity exposures are price fluctuations on forecasted purchases of copper and aluminum and related products. As part of the Company's risk management strategy, derivative instruments are selectively used in an effort to minimize the impact of these exposures. Foreign exchange forwards and options are utilized to hedge foreign currency exposures impacting sales or cost of sales transactions, firm commitments and the fair value of assets and liabilities, while swap and option contracts may be used to minimize the effect of commodity price fluctuations on the cost of sales. Non-U.S. dollar obligations are utilized to reduce foreign currency risk associated with the Company's net investments in foreign operations. All derivatives are associated with specific underlying exposures and the Company does not hold derivatives for trading or speculative purposes. The duration of hedge positions is generally two years or less, except for the Company's net investment hedges. All derivatives are accounted for under ASC 815, Derivatives and Hedging , and recognized at fair value. For derivatives hedging variability in future cash flows, the effective portion of any gain or loss is deferred in stockholders' equity and recognized when the underlying hedged transaction impacts earnings. The majority of the Company's derivatives that are designated as hedges and qualify for hedge accounting are cash flow hedges. For derivatives hedging the fair value of existing assets or liabilities, both the gain or loss on the derivative and the offsetting loss or gain on the hedged item are recognized in earnings each period. Currency fluctuations on non-U.S. dollar obligations that have been designated as hedges of net investments in foreign operations are recognized in accumulated other comprehensive income (loss) and reclassified to income in the same period when a foreign operation is sold and the gain or loss related to the sale is included in income. To the extent that any hedge is not fully effective at offsetting changes in the underlying hedged item, there could be a net earnings impact. The Company also uses derivatives to hedge economic exposures that do not receive hedge accounting under ASC 815. The underlying exposures for these hedges relate primarily to purchases of commodity-based components used in the Company's manufacturing processes, and the revaluation of certain foreign-currency-denominated assets and liabilities. Gains or losses from the ineffective portion of any hedge, as well as any gains or losses on derivative instruments not designated as hedges, are recognized in the income statement immediately. Counterparties to derivative arrangements are companies with high credit ratings, and the Company has bilateral collateral arrangements with them for which credit rating-based posting thresholds vary depending on the arrangement. If credit ratings on the Company's debt fall below preestablished levels, counterparties can require immediate full collateralization on all instruments in net liability positions. No collateral was posted with counterparties and none was held by the Company at year end. If contractual thresholds had been exceeded, the maximum collateral the Company could have been required to post was $8 . The Company can also demand full collateralization of instruments in net asset positions should any of the Company's counterparties' credit ratings fall below certain thresholds. Risk from credit loss when derivatives are in asset positions is not considered material. The Company has master netting arrangements in place with its counterparties that allow the offsetting of certain derivative-related amounts receivable and payable when settlement occurs in the same period. Accordingly, counterparty balances are netted in the consolidated balance sheet and are reported in other current assets or accrued expenses as appropriate, depending on positions with counterparties as of the balance sheet date. See Note 8. Income Taxes The provision for income taxes is based on pretax income reported in the consolidated statements of earnings and tax rates currently enacted in each jurisdiction. Certain income and expense items are recognized in different time periods for financial reporting and income tax filing purposes, and deferred income taxes are provided for the effect of temporary differences. The Company also provides for withholding taxes and any applicable U.S. income taxes on earnings intended to be repatriated from non-U.S. locations. No provision has been made for these taxes on approximately $4.0 billion of undistributed earnings of non-U.S. subsidiaries as of September 30, 2019 , as these earnings are considered indefinitely invested or otherwise retained for continuing international operations. Recognition of withholding taxes and any applicable U.S. income taxes on undistributed non-U.S. earnings would be triggered by a management decision to repatriate those earnings. Determination of the amount of taxes that might be paid on these undistributed earnings if eventually remitted is not practicable. See Note 14.

Revenue Recognition [Abstract]
Revenue from Contract with Customer	REVENUE RECOGNITION The following table summarizes the balances of the Company's unbilled receivables (contract assets), which are reported in Other current assets, and its customer advances (contract liabilities), which are reported in Accrued expenses. 2018 2019 Unbilled receivables (contract assets) $ 321 456 Customer advances (contract liabilities) (510 ) (519 ) Net contract liabilities $ (189 ) (63 ) The majority of the Company's contract balances relate to arrangements where revenue is recognized over time and payments from customers are made according to a contractual billing schedule. The decrease in net contract liabilities was due to revenue recognized for performance completed during the period which exceeded customer billings. Revenue recognized for 2019 included approximately $400 that was included in the beginning contract liability balance. Other factors that impacted the change in net contract liabilities were immaterial. Revenue recognized for 2019 for performance obligations that were fully satisfied in previous periods, including cumulative catchup adjustments on the Company's long-term contracts, was not material. Capitalized amounts related to incremental costs to obtain customer contracts and costs to fulfill contracts are immaterial. As of September 30, 2019, the Company's backlog relating to unsatisfied (or partially unsatisfied) performance obligations in contracts with its customers was approximately $5.1 billion . The Company expects to recognize approximately 85 percent of its remaining performance obligations as revenue over the next 12 months , with the remainder substantially over the subsequent two years thereafter. See Note 18 for additional information about the Company's revenues.

Restructuring Charges [Abstract]
Restructuring costs	RESTRUCTURING COSTS Each year the Company incurs costs to size its businesses to levels appropriate for current economic conditions and to continually improve its cost structure and operational efficiency, deploy assets globally, and remain competitive on a worldwide basis. Costs result from numerous individual actions implemented across the Company's various operating units on an ongoing basis and can include costs for moving facilities to best-cost locations, restarting plants after relocation or geographic expansion to better serve local markets, reducing forcecount or the number of facilities, exiting certain product lines, and other costs resulting from asset deployment decisions (such as contract termination costs, asset write-downs and vacant facility costs). Restructuring expenses were $95 , $65 and $78 for 2019 , 2018 and 2017 , respectively, and included $7 , $19 and $25 related to acquisitions, respectively. Restructuring costs by business segment follows: 2017 2018 2019 Automation Solutions $ 63 41 65 Climate Technologies 10 20 20 Tools & Home Products 2 3 7 Commercial & Residential Solutions 12 23 27 Corporate 3 1 3 Total $ 78 65 95 Costs incurred in 2019 , 2018 and 2017 primarily related to the deployment of resources to better serve local markets and higher growth areas, and the integration of acquisitions.

General Discussion of Derivative Instruments and Hedging Activities [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS Hedging Activities As of September 30, 2019 , the notional amount of foreign currency hedge positions was approximately $2.3 billion , while commodity hedge contracts totaled approximately $117 (primarily 48 million pounds of copper and aluminum). All derivatives receiving hedge accounting are cash flow hedges. The majority of hedging gains and losses deferred as of September 30, 2019 are expected to be recognized over the next 12 months as the underlying forecasted transactions occur. Gains and losses on foreign currency derivatives reported in Other deductions, net reflect hedges of balance sheet exposures that do not receive hedge accounting. Amounts included in earnings and other comprehensive income follow: Gain (Loss) to Earnings Gain (Loss) to OCI 2017 2018 2019 2017 2018 2019 Location Commodity Cost of sales $ 10 13 (11 ) 25 (7 ) (10 ) Foreign currency Sales, cost of sales (15 ) 2 13 30 9 6 Foreign currency Other deductions, net (39 ) (15 ) 66 Total $ (44 ) — 68 55 2 (4 ) Regardless of whether derivatives receive hedge accounting, the Company expects hedging gains or losses to be essentially offset by losses or gains on the related underlying exposures. The amounts ultimately recognized will differ from those presented above for open positions, which remain subject to ongoing market price fluctuations until settlement. Derivatives receiving hedge accounting are highly effective and no amounts were excluded from the assessment of hedge effectiveness, including for the net investment hedge described below. Hedge ineffectiveness was immaterial in all years shown. Net Investment Hedge In January 2019, the Company issued €500 of 1.25% notes due October 2025 and €500 of 2.0% notes due October 2029. In May 2019, the Company issued €500 of 0.375% notes due May 2024. The net proceeds from the sale of the notes were used to repay commercial paper borrowings and for general corporate purposes. The euro notes reduce foreign currency risk associated with the Company's international subsidiaries that use the euro as their functional currency and have been designated as a hedge of a portion of the investment in these operations. A pretax gain of $70 ( $54 after-tax) was recognized in other comprehensive income (loss) related to the net investment hedge during 2019. Amounts deferred in accumulated other comprehensive income (loss) will remain until the hedged investment is sold or substantially liquidated. Fair Value Measurement The estimated fair value of long-term debt was $5.3 billion and $4.0 billion , respectively, as of September 30, 2019 and 2018 , which exceeded the carrying value by $469 and $135 , respectively. The fair values of commodity and foreign currency contracts were reported in Other current assets and Accrued expenses as summarized below: 2018 2019 Assets Liabilities Assets Liabilities Commodity $ 1 10 — 8 Foreign currency $ 35 11 29 12

Based on foreign currency exchange rates as of September 30, 2019 , future benefit payments by non-U.S. plans are estimated to be $74 in 2020 , $72 in 2021 , $78 in 2022 , $80 in 2023 , $84 in 2024 and $462 in total over the five years 2025 through 2029. The Company expects to contribute approximately $60 to its retirement plans in 2020 . The weighted-average assumptions used in the valuation of pension benefits follow: U.S. Plans Non-U.S. Plans 2017 2018 2019 2017 2018 2019 Net pension expense Discount rate used to determine service cost 3.75 % 3.95 % 4.33 % 2.3 % 2.6 % 2.7 % Discount rate used to determine interest cost 2.90 % 3.25 % 3.98 % 2.3 % 2.6 % 2.7 % Expected return on plan assets 7.25 % 7.00 % 7.00 % 6.2 % 5.7 % 6.1 % Rate of compensation increase 3.25 % 3.25 % 3.25 % 3.2 % 3.4 % 3.5 % Benefit obligations Discount rate 3.76 % 4.26 % 3.22 % 2.6 % 2.7 % 1.9 % Rate of compensation increase 3.25 % 3.25 % 3.25 % 3.4 % 3.5 % 3.7 % The discount rate for the U.S. retirement plans was 3.22 percent as of September 30, 2019 . An actuarially developed, company-specific yield curve is used to determine the discount rate. To determine the service and interest cost components of pension expense for its U.S. retirement plans, the Company applies the specific spot rates along the yield curve, rather than the single weighted-average rate, to the projected cash flows to provide more precise measurement of these costs. The expected return on plan assets assumption is determined by reviewing the investment returns of the plans for the past 10 years plus longer-term historical returns of an asset mix approximating the Company's asset allocation targets, and periodically comparing these returns to expectations of investment advisors and actuaries to determine whether long-term future returns are expected to differ significantly from the past. The Company's asset allocations at September 30, 2019 and 2018 , and weighted-average target allocations follow: U.S. Plans Non-U.S. Plans 2018 2019 Target 2018 2019 Target Equity securities 62 % 53 % 50-60% 52 % 42 % 40-50% Debt securities 34 46 40-50 38 47 45-55 Other 4 1 0-10 10 11 5-15 Total 100 % 100 % 100% 100 % 100 % 100% The primary objective for the investment of pension assets is to secure participant retirement benefits by earning a reasonable rate of return. Plan assets are invested consistent with the provisions of the prudence and diversification rules of ERISA and with a long-term investment horizon. The Company continuously monitors the value of assets by class and routinely rebalances to remain within target allocations. The equity strategy is to minimize concentrations of risk by investing primarily in a mix of companies that are diversified across geographies, market capitalization, style, sectors and industries worldwide. The approach for bonds emphasizes investment-grade corporate and government debt with maturities matching a portion of the longer duration pension liabilities. The bonds strategy also includes a high-yield element which is generally shorter in duration. For diversification, a small portion of U.S. plan assets is allocated to private equity partnerships and real asset fund investments, providing opportunities for above market returns. Leveraging techniques are not used and the use of derivatives in any fund is limited and inconsequential. The fair values of defined benefit pension assets as of September 30, organized by asset class and by the fair value hierarchy of ASC 820, Fair Value Measurement, follow. Investments valued based on the net asset value (NAV) of fund units held, as derived from the fair value of the underlying assets, are excluded from the fair value hierarchy. Level 1 Level 2 Level 3 Measured at NAV Total % 2019 U.S. equities $ 789 5 386 284 1,464 27 % International equities 459 15 — 615 1,089 20 % Emerging market equities — — — 213 213 4 % Corporate bonds — 1,008 — 464 1,472 27 % Government bonds 0 512 — 540 1,052 19 % High-yield bonds — — — — — — % Other 1 8 129 64 202 3 % Total $ 1,249 1,548 515 2,180 5,492 100 % 2018 U.S. equities $ 968 5 350 320 1,643 30 % International equities 595 21 — 745 1,361 25 % Emerging market equities — — — 243 243 5 % Corporate bonds — 696 — 423 1,119 20 % Government bonds — 350 — 438 788 14 % High-yield bonds — — — 10 10 — % Other 107 6 121 78 312 6 % Total $ 1,670 1,078 471 2,257 5,476 100 % Asset Classes U.S. equities reflect companies domiciled in the U.S., including multinational companies. International equities are comprised of companies domiciled in developed nations outside the U.S. Emerging market equities are comprised of companies domiciled in portions of Asia, Eastern Europe and Latin America. Corporate bonds represent investment-grade debt of issuers primarily from the U.S. Government bonds include investment-grade instruments issued by federal, state and local governments, primarily in the U.S. High-yield bonds include noninvestment-grade debt from a diverse group of developed market issuers. Other includes cash, interests in mixed asset funds investing in commodities, natural resources, agriculture, real estate and infrastructure funds, life insurance contracts (U.S.), and shares in certain general investment funds of financial institutions or insurance arrangements (non-U.S.) that typically ensure no market losses or provide for a small minimum return guarantee. Fair Value Hierarchy Categories Valuations of Level 1 assets for all classes are based on quoted closing market prices from the principal exchanges where the individual securities are traded. Cash is valued at cost, which approximates fair value. Debt securities categorized as Level 2 assets are generally valued based on independent broker/dealer bids or by comparison to other debt securities having similar durations, yields and credit ratings. U.S. equity securities classified as Level 3 are fund investments in private companies. Valuation techniques and inputs for these assets include discounted cash flow analysis, earnings multiple approaches, recent transactions, transfer restrictions, prevailing discount rates, volatilities, credit ratings and other factors. In the Other class, interests in mixed asset funds are Level 2, and U.S. life insurance contracts and non-U.S. general fund investments and insurance arrangements are Level 3. Investments measured at net asset value are primarily nonexchange-traded commingled or collective funds where the underlying securities have observable prices available from active markets. Details of the changes in value for Level 3 assets follow: 2018 2019 Level 3, beginning $ 451 471 Gains (Losses) on assets held 1 — Gains (Losses) on assets sold 37 34 Purchases, sales and settlements, net (18 ) 10 Level 3, ending $ 471 515

Postemployment Benefits [Abstract]
Postretirement Plans	POSTRETIREMENT PLANS The Company sponsors unfunded postretirement benefit plans (primarily health care) for certain U.S. retirees and their dependents. The components of net postretirement benefits expense for the years ended September 30 follow: 2017 2018 2019 Service cost $ 1 1 1 Interest cost 6 6 5 Net amortization (19 ) (19 ) (18 ) Net postretirement expense $ (12 ) (12 ) (12 ) Details of the changes in actuarial present value of accumulated postretirement benefit obligations follow: 2018 2019 Benefit obligation, beginning $ 174 149 Service cost 1 1 Interest cost 6 5 Actuarial (gain) loss (19 ) 5 Benefits paid (13 ) (13 ) Benefit obligation, ending (recognized in balance sheet) $ 149 147 As of September 30, 2019 there were $118 of deferred actuarial gains in accumulated other comprehensive income, of which approximately $13 will be amortized into earnings in 2020 . The discount rates used to measure the benefit obligation as of September 30, 2019 , 2018 and 2017 were 2.99 percent , 4.08 percent and 3.45 percent , respectively. The health care cost trend rate used for 2020 is assumed to be 7.0 percent initially and was assumed to be 7.2 percent in 2019, declining to 5.0 percent over the subsequent nine years . A one percentage point increase or decrease in the health care cost trend rate assumption for either year would have an inconsequential impact on postretirement benefits expense and the benefit obligation. The Company estimates that future health care benefit payments will be approximately $12 per year for 2020 through 2024 , and $49 in total over the five years 2025 through 2029 .

Contingent Liabilities and Comm

Contingent Liabilities and Commitments	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	CONTINGENT LIABILITIES AND COMMITMENTS The Company is a party to a number of pending legal proceedings and claims, including those involving general and product liability (including asbestos) and other matters, several of which claim substantial amounts of damages. The Company accrues for such liabilities when it is probable that future costs (including legal fees and expenses) will be incurred and such costs can be reasonably estimated. Accruals are based on developments to date; management's estimates of the outcomes of these matters; and the Company's experience in contesting, litigating and settling similar matters. The Company engages an outside expert to develop an actuarial estimate of its expected costs to resolve all pending and future asbestos claims, including defense costs, as well as its related insurance receivables. The reserve for asbestos litigation, which is recorded on an undiscounted basis, is based on projected claims through 2065. Although it is not possible to predict the ultimate outcome of these matters, the Company historically has been largely successful in defending itself against claims and suits that have been brought against it, and will continue to defend itself vigorously in all such matters. While the Company believes a material adverse impact is unlikely, given the inherent uncertainty of litigation, a remote possibility exists that a future development could have a material adverse impact on the Company. The Company enters into certain indemnification agreements in the ordinary course of business in which the indemnified party is held harmless and is reimbursed for losses incurred from claims by third parties, usually up to a prespecified limit. In connection with divestitures of certain assets or businesses, the Company often provides indemnities to the buyer with respect to certain matters including, for example, environmental or unidentified tax liabilities related to periods prior to the disposition. Because of the uncertain nature of the indemnities, the maximum liability cannot be quantified. As such, contingent liabilities are recorded when they are both probable and reasonably estimable. Historically, payments under indemnity arrangements have been inconsequential. At September 30, 2019 , there were no known contingent liabilities (including guarantees, pending litigation, taxes and other claims) that management believes will be material in relation to the Company's financial statements, nor were there any material commitments outside the normal course of business.

The Act includes a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent in calendar year 2018 along with the elimination of certain deductions and credits, and a one-time “deemed repatriation” of accumulated non-U.S. earnings. During 2018, the Company recognized a net tax benefit of $189 ( $0.30 per share) due to impacts of the Act, consisting of a $94 benefit on revaluation of net deferred income tax liabilities to the lower tax rate, $35 of expense for the tax on deemed repatriation of accumulated non-U.S. earnings and withholding taxes, and the reversal of $130 accrued in previous periods for the planned repatriation of non-U.S. cash. The Company completed its accounting for the Act in the first quarter of fiscal 2019. Effective in fiscal 2019, the Act also subjects the Company to U.S. tax on global intangible low-taxed income earned by certain of its non-U.S. subsidiaries. The Company has elected to recognize this tax as a period expense when it is incurred. Non-U.S. tax holidays reduce tax rates in certain jurisdictions and are expected to expire over the next three years . Following are changes in unrecognized tax benefits before considering recoverability of any cross-jurisdictional tax credits (U.S. federal, state and non-U.S.) and temporary differences. The amount of unrecognized tax benefits is not expected to change significantly within the next 12 months. 2018 2019 Unrecognized tax benefits, beginning $ 132 158 Additions for current year tax positions 13 15 Additions for prior year tax positions 8 18 Reductions for prior year tax positions (8 ) (22 ) Acquisitions and divestitures 21 4 Reductions for settlements with tax authorities (3 ) (5 ) Reductions for expiration of statutes of limitations (5 ) (9 ) Unrecognized tax benefits, ending $ 158 159 If none of the unrecognized tax benefits shown is ultimately paid, the tax provision and the calculation of the effective tax rate would be favorably impacted by $124 , which is net of cross-jurisdictional tax credits and temporary differences. The Company accrues interest and penalties related to income taxes in income tax expense. Total interest and penalties recognized were $4 , $2 and $(1) in 2019 , 2018 and 2017 , respectively. As of September 30, 2019 and 2018 , total accrued interest and penalties were $27 and $23 , respectively. The U.S. is the major jurisdiction for which the Company files income tax returns. U.S. federal tax returns are closed through 2013. The status of state and non-U.S. tax examinations varies due to the numerous legal entities and jurisdictions in which the Company operates. The principal items that gave rise to deferred income tax assets and liabilities follow: 2018 2019 Deferred tax assets: Net operating losses and tax credits $ 396 407 Accrued liabilities 238 228 Postretirement and postemployment benefits 37 36 Employee compensation and benefits 119 110 Pensions — 95 Other 151 121 Total $ 941 997 Valuation allowances $ (341 ) (307 ) Deferred tax liabilities: Intangibles $ (693 ) (637 ) Pensions (43 ) — Property, plant and equipment (187 ) (195 ) Undistributed non-U.S. earnings (52 ) (49 ) Other (35 ) (39 ) Total $ (1,010 ) (920 ) Net deferred income tax liability $ (410 ) (230 ) Total income taxes paid were approximately $650 , $680 and $1,420 in 2019 , 2018 and 2017 , respectively. Approximately half of the $407 of net operating losses and tax credits expire over the next 5 years, while most of the remainder can be carried forward indefinitely.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-based Compensation [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION The Company's stock-based compensation plans include stock options, performance shares, restricted stock and restricted stock units. Although the Company has discretion, shares distributed under these plans are issued from treasury stock. Stock Options The Company's stock option plans permit key officers and employees to purchase common stock at specified prices, which are equal to 100 percent of the closing market price of the Company's stock on the date of grant. Options generally vest one-third in each of the three years subsequent to grant and expire 10 years from the date of grant. Compensation expense is recognized ratably over the vesting period based on the number of options expected to vest. As of September 30, 2019 , 11.6 million options were available for grant under the plans. Changes in shares subject to options during the year ended September 30, 2019 follow (shares in thousands): Weighted- Average Exercise Price Per Share Shares Total Average Remaining Life (Years) Beginning of year $ 56.37 7,801 Options granted $ — — Options exercised $ 49.35 (854 ) Options canceled $ 57.85 (32 ) End of year $ 57.23 6,915 $ 67 4.2 Exercisable at end of year $ 57.27 6,795 $ 66 4.2 The weighted-average grant date fair value per option was $12.13 and $8.36 in 2018 and 2017 , respectively. Cash received for option exercises was $40 in 2019 , $143 in 2018 and $148 in 2017 . The total intrinsic value of options exercised in 2019 , 2018 and 2017 was $16 , $53 and $36 , while the tax benefit from tax deductions related to option exercises was $8 , $7 and $2 , respectively. The grant date fair value of options is estimated using the Black-Scholes option-pricing model. The weighted-average assumptions used in valuations for 2018 and 2017 are, respectively: risk-free interest rate, based on U.S. Treasury yield, 2.4 percent and 1.7 percent ; dividend yield, 2.9 percent and 3.6 percent ; and expected volatility, based on historical volatility, 23 percent and 24 percent . The expected life of each option awarded is seven years based on historical experience and expected future exercise patterns. Performance Shares, Restricted Stock and Restricted Stock Units The Company's incentive shares plans include performance shares awards which distribute the value of common stock to key management employees subject to certain operating performance conditions and other restrictions. The form of distribution is primarily shares of common stock, with a portion in cash. Compensation expense for performance shares is recognized over the service period based on the number of shares ultimately expected to be earned. Performance shares awards are accounted for as liabilities in accordance with ASC 718, Compensation - Stock Compensation , with compensation expense adjusted at the end of each reporting period to reflect the change in fair value of the awards. As of September 30, 2016, 4,944,575 performance shares awarded primarily in 2013 were outstanding, contingent on the Company achieving its performance objectives through 2016 and the provision of additional service by employees. The objectives for these shares were met at the 86 percent level at the end of 2016, or 4,252,335 shares. Of these, 2,549,083 shares were distributed in early 2017 as follows: 1,393,715 issued as shares, 944,002 withheld for income taxes, and the value of 211,366 paid in cash. An additional 1,691,986 shares were distributed at the end of 2017 to employees who provided one additional year of service as follows: 1,070,264 issued as shares, 616,734 withheld for income taxes, and the value of 4,988 paid in cash. There were 11,266 shares canceled and not distributed. As of September 30, 2018, 1,874,750 shares awarded primarily in 2016 were outstanding, contingent on the Company achieving its performance objectives through 2018. The objectives for these shares were met at the 97 percent level at the end of 2018 and 1,818,510 shares were distributed in early 2019 as follows: 1,023,789 issued as shares, 588,094 withheld for income taxes, and the value of 206,627 paid in cash. As of September 30, 2019, 1,877,650 shares awarded primarily in 2017 were outstanding, contingent on the Company achieving its performance objectives through 2019. The objectives for these shares were met at the 107 percent level at the end of 2019 and 2,009,085 shares will be distributed in early 2020. Additionally, the rights to receive a maximum of 1,811,605 and 2,125,954 common shares were awarded in 2019 and 2018, respectively, under the new performance shares program, and are outstanding and contingent upon the Company achieving its performance objectives through 2021 and 2020, respectively. Incentive shares plans also include restricted stock awards which involve distribution of common stock to key management employees subject to cliff vesting at the end of service periods ranging from three to ten years. The fair value of restricted stock awards is determined based on the average of the high and low market prices of the Company's common stock on the date of grant, with compensation expense recognized ratably over the applicable service period. In 2019 , 250,000 shares of restricted stock vested as a result of participants fulfilling the applicable service requirements. Consequently, 148,707 shares were issued while 101,293 shares were withheld for income taxes in accordance with minimum withholding requirements. As of September 30, 2019 , there were 1,262,700 shares of unvested restricted stock outstanding. The total fair value of shares distributed under incentive shares plans was $145 , $20 and $245 , respectively, in 2019 , 2018 and 2017 , of which $73 , $9 and $101 was paid in cash, primarily for tax withholding. As of September 30, 2019 , 8.8 million shares remained available for award under incentive shares plans. Changes in shares outstanding but not yet earned under incentive shares plans during the year ended September 30, 2019 follow (shares in thousands; assumes 100 percent payout of unvested awards): Shares Average Grant Date Beginning of year 6,898 $ 54.69 Granted 1,740 $ 68.99 Earned/vested (2,068 ) $ 47.93 Canceled (245 ) $ 59.85 End of year 6,325 $ 60.63 Total compensation expense for stock options and incentive shares was $120 , $216 and $115 for 2019 , 2018 and 2017 , respectively, of which $5 was included in discontinued operations for 2017. The decrease in expense in 2019 reflects a decreasing stock price in the current year compared to an increasing stock price in the prior year. The increase in expense for 2018 reflects an increase in the Company's stock price and progress toward achieving its performance objectives. Income tax benefits recognized in the income statement for these compensation arrangements during 2019 , 2018 and 2017 were $20 , $42 and $33 , respectively. As of September 30, 2019 , total unrecognized compensation expense related to unvested shares awarded under these plans was $138 , which is expected to be recognized over a weighted-average period of 1.6 years. In addition to the employee stock option and incentive shares plans, in 2019 the Company awarded 17,466 shares of restricted stock and 2,264 restricted stock units under the restricted stock plan for non-management directors. As of September 30, 2019 , 139,635 shares were available for issuance under this plan.

Accounting Policies [Abstract]
Financial Statement Presentation	Financial Statement Presentation The preparation of the financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect reported amounts and related disclosures. Actual results could differ from these estimates. Certain prior year amounts have been reclassified to conform with current year presentation. On October 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers , which updated and consolidated revenue recognition guidance from multiple sources into a single, comprehensive standard to be applied for all contracts with customers. The fundamental principle of the revised standard is to recognize revenue based on the transfer of goods and services to customers at the amount the Company expects to be entitled to in exchange for those goods and services. The Company adopted the new standard using the modified retrospective approach and applied the guidance to open contracts which were not completed at the date of adoption. The cumulative effect of adoption resulted in a $30 increase to beginning retained earnings as of October 1, 2018. This increase primarily related to contracts where a portion of revenue for delivered goods or services was previously deferred due to contingent payment terms. The adoption of ASC 606 did not materially impact the Company's consolidated financial statements as of and for the year ended September 30, 2019. Amounts reported for the years ended September 30, 2018 and 2017 continue to be reported in accordance with the Company's historic accounting under ASC 605, Revenue Recognition . In the first quarter of fiscal 2019, the Company adopted updates to ASC 715, Compensation - Retirement Benefits , which permit only the service cost component of net periodic pension and postretirement expense to be reported with compensation costs, while all other components are required to be reported separately in other deductions. These updates were adopted retrospectively and resulted in the reclassification of $40 of income and $38 of expense in 2018 and 2017, respectively, from cost of sales and SG&A to other deductions, net. Segment earnings were not impacted by the updates to ASC 715. In the fourth quarter of 2018, the Company adopted updates to ASC 220, Comprehensive Income , which permit reclassification of stranded tax effects resulting from U.S. tax reform from accumulated other comprehensive income to retained earnings. The Company reclassified $100 of stranded tax effects from accumulated other comprehensive income to retained earnings upon adoption of these updates. See Note 17. In the first quarter of 2018, the Company adopted updates to ASC 740, Income Taxes , which require recognition of the income tax effects of intra-entity transfers of assets other than inventory when the transfer occurs, on a modified retrospective basis. The adoption of these updates resulted in an increase of $3 to retained earnings. In the first quarter of 2018, the Company adopted updates to ASC 330, Inventory , which changed the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. These updates were adopted prospectively and did not materially impact the Company's financial statements. In the fourth quarter of 2017, the Company adopted updates to ASC 718, Compensation - Stock Compensation , which require all excess tax benefits and deficiencies related to share-based payments to be recognized in income tax expense rather than through additional paid-in-capital, and to be presented as operating cash flows instead of financing. These updates did not materially impact the Company's financial statements. In the fourth quarter of 2017, the Company adopted updates to ASC 820, Fair Value Measurement , which require investments measured using the net asset value per share practical expedient to be removed from the fair value hierarchy and separately reported when making disclosures. These updates did not change the determination of fair value for any investments. Adoption affected disclosure presentation only; there was no impact on the Company’s financial results.
Principles Of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its controlled affiliates. Intercompany transactions, profits and balances are eliminated in consolidation. Investments of 20 percent to 50 percent of the voting shares of other entities are accounted for by the equity method. Investments in publicly traded companies of less than 20 percent are carried at fair value, with changes in fair value reflected in accumulated other comprehensive income. Investments in nonpublicly traded companies of less than 20 percent are carried at cost, minus impairment, and adjusted for observable price changes in orderly transactions.
Foreign Currency Translation	Foreign Currency Translation The functional currency for most of the Company's non-U.S. subsidiaries is the local currency. Adjustments resulting from translating local currency financial statements into U.S. dollars are reflected in accumulated other comprehensive income.
Cash Equivalents	Cash Equivalents Cash equivalents consist of highly liquid investments with original maturities of three months or less.
Inventories	Inventories Inventories are stated at the lower of cost and net realizable value. The majority of inventory is valued based on standard costs, which approximate average costs, while the remainder is principally valued on a first-in, first-out basis. Cost standards are revised at the beginning of each year. The annual effect of resetting standards plus any operating variances incurred during each period are allocated to inventories and recognized in cost of sales as product is sold. Following are the components of inventory as of September 30: 2018 2019 Finished products $ 592 578 Raw materials and work in process 1,221 1,302 Total inventories $ 1,813 1,880
Fair Value Measurements	Fair Value Measurement ASC 820, Fair Value Measurement , establishes a formal hierarchy and framework for measuring certain financial statement items at fair value, and requires disclosures about fair value measurements and the reliability of valuation inputs. Under ASC 820, measurement assumes the transaction to sell an asset or transfer a liability occurs in the principal or at least the most advantageous market for that asset or liability. Within the hierarchy, Level 1 instruments use observable market prices for an identical item in active markets and have the most reliable valuations. Level 2 instruments are valued through broker/dealer quotation or other approaches using market-observable inputs for similar items in active markets, including forward and spot prices, interest rates and volatilities. Level 3 instruments are valued using inputs not observable in an active market, such as company-developed future cash flow estimates, and are considered the least reliable. Valuations for all of the Company's financial instruments fall within Level 2. The fair value of the Company's long-term debt is Level 2, estimated using current interest rates and pricing from financial institutions and other market sources for debt with similar maturities and characteristics.
Property, Plant and Equipment	Property, Plant and Equipment The Company records investments in land, buildings, and machinery and equipment at cost. Depreciation is computed principally using the straight-line method over estimated service lives, which for principal assets are 30 to 40 years for buildings and 8 to 12 years for machinery and equipment. Long-lived tangible assets are reviewed for impairment whenever events or changes in business circumstances indicate the carrying value of the assets may not be recoverable. Impairment losses are recognized based on estimated fair values if the sum of estimated future undiscounted cash flows of the related assets is less than the carrying values. The components of property, plant and equipment as of September 30 follow: 2018 2019 Land $ 316 336 Buildings 2,145 2,219 Machinery and equipment 5,470 5,645 Construction in progress 439 471 Property, plant and equipment, at cost 8,370 8,671 Less: Accumulated depreciation 4,808 5,029 Property, plant and equipment, net $ 3,562 3,642
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Assets and liabilities acquired in business combinations are accounted for using the acquisition method and recorded at their respective fair values. Substantially all goodwill is assigned to the reporting unit that acquires a business. A reporting unit is an operating segment as defined in ASC 280, Segment Reporting , or a business one level below an operating segment if discrete financial information for that business unit is prepared and regularly reviewed by the segment manager. The Company conducts annual impairment tests of goodwill in the fourth quarter. If an initial assessment indicates it is more likely than not goodwill might be impaired, it is evaluated by comparing the reporting unit's estimated fair value to its carrying value. Goodwill is also tested for impairment between annual tests if events or circumstances indicate the fair value of a unit may be less than its carrying value. If the carrying amount exceeds the estimated fair value, impairment is recognized to the extent that recorded goodwill exceeds the implied fair value of that goodwill. Estimated fair values of reporting units are Level 3 measures and are developed generally under an income approach that discounts estimated future cash flows using risk-adjusted interest rates, as well as earnings multiples or other techniques as warranted. Fair values are subject to changes in underlying economic conditions. All of the Company's identifiable intangible assets are subject to amortization on a straight-line basis over their estimated useful lives. Identifiable intangibles consist of intellectual property such as patents and trademarks, customer relationships and capitalized software. Identifiable intangibles are also subject to evaluation for potential impairment if events or circumstances indicate the carrying amount may not be recoverable. See Note 7.
Product Warranty	Product Warranty Warranties vary by product line and are competitive for the markets in which the Company operates. Warranties are largely offered to provide assurance that the product will function as intended and generally extend for a period of one to two years from the date of sale or installation. Provisions for warranty expense are estimated at the time of sale based on historical experience and adjusted quarterly for any known issues that may arise. Product warranty expense is less than one percent of sales.
Revenue Recognition	Revenue Recognition Emerson is a global manufacturer that combines technology and engineering to provide innovative solutions to its customers, largely in the form of tangible products. The Company evaluates its contracts with customers to identify the promised goods or services and recognizes revenue for the identified performance obligations at the amount the Company expects to be entitled to in exchange for those goods or services. A performance obligation is a promise in a contract to transfer a distinct good or service to a customer. Revenue is recognized when, or as, performance obligations are satisfied and control has transferred to the customer, typically when products are shipped or delivered, title and risk of loss pass to the customer, and the Company has a present right to payment. The vast majority of the Company's revenues relate to a broad offering of manufactured products which are recognized at the point in time when control transfers, generally in accordance with shipping terms. A portion of the Company's revenues relate to the sale of software and post-contract customer support, parts and labor for repairs, and engineering services. In limited circumstances, contracts include multiple performance obligations, where revenue is recognized separately for each good or service, as well as contracts where revenue is recognized over time as control transfers to the customer. Revenue is recognized over time for approximately 5 percent of the Company's revenues. These contracts largely relate to projects in the Process Control Systems & Solutions product offering within the Automation Solutions segment where revenue is recognized using the percentage-of-completion method to reflect the transfer of control over time, while a small amount is attributable to long-term maintenance and service contracts where revenue is typically recognized on a straight-line basis as the services are provided. Approximately 5 percent of revenues relate to sales arrangements with multiple performance obligations, principally in the Automation Solutions segment. Tangible products represent a large majority of the delivered items in contracts with multiple performance obligations or where revenue is recognized over time, while a smaller portion is attributable to installation, service and maintenance. For revenues recognized over time, the Company typically uses an input method to determine progress and recognize revenue, based on costs incurred. The Company believes costs incurred closely correspond with its performance under the contract and the transfer of control to the customer. In sales arrangements that involve multiple performance obligations, revenue is allocated based on the relative standalone selling price for each performance obligation. Observable selling prices from actual transactions are used whenever possible. In other instances, the Company determines the standalone selling price based on third-party pricing or management's best estimate. Generally, contract duration is short-term, and cancellation, termination or refund provisions apply only in the event of contract breach and are rarely invoked. Payment terms vary but are generally short-term in nature. The Company's long-term contracts, where revenue is generally recognized over time, are typically billed as work progresses in accordance with the contract terms and conditions, either at periodic intervals or upon achievement of certain milestones. The timing of revenue recognition and billings under these contracts results in either unbilled receivables (contract assets) when revenue recognized exceeds billings, or customer advances (contract liabilities) when billings exceed revenue recognized. Unbilled receivables are reclassified to accounts receivable when an unconditional right to consideration exists, typically when a milestone in the contract is achieved. The Company does not evaluate whether the transaction price includes a significant financing component for contracts where the time between cash collection and performance is less than one year. Certain arrangements with customers include variable consideration, typically in the form of rebates, cash discounts or penalties. In limited circumstances, the Company sells products with a general right of return. In most instances, returns are limited to product quality issues. The Company records a reduction to revenue at the time of sale to reflect the ultimate amount of consideration it expects to receive. The Company's estimates are updated quarterly based on historical experience, trend analysis, and expected market conditions. Variable consideration is typically not constrained at the time revenue is recognized. See Notes 2 and 18 for additional information about the Company's revenues.
Derivatives and Hedging	Derivatives and Hedging In the normal course of business, the Company is exposed to changes in interest rates, foreign currency exchange rates and commodity prices due to its worldwide presence and diverse business profile. The Company's foreign currency exposures relate to transactions denominated in currencies that differ from the functional currencies of its business units, primarily in euros, Mexican pesos and Singapore dollars. Primary commodity exposures are price fluctuations on forecasted purchases of copper and aluminum and related products. As part of the Company's risk management strategy, derivative instruments are selectively used in an effort to minimize the impact of these exposures. Foreign exchange forwards and options are utilized to hedge foreign currency exposures impacting sales or cost of sales transactions, firm commitments and the fair value of assets and liabilities, while swap and option contracts may be used to minimize the effect of commodity price fluctuations on the cost of sales. Non-U.S. dollar obligations are utilized to reduce foreign currency risk associated with the Company's net investments in foreign operations. All derivatives are associated with specific underlying exposures and the Company does not hold derivatives for trading or speculative purposes. The duration of hedge positions is generally two years or less, except for the Company's net investment hedges. All derivatives are accounted for under ASC 815, Derivatives and Hedging , and recognized at fair value. For derivatives hedging variability in future cash flows, the effective portion of any gain or loss is deferred in stockholders' equity and recognized when the underlying hedged transaction impacts earnings. The majority of the Company's derivatives that are designated as hedges and qualify for hedge accounting are cash flow hedges. For derivatives hedging the fair value of existing assets or liabilities, both the gain or loss on the derivative and the offsetting loss or gain on the hedged item are recognized in earnings each period. Currency fluctuations on non-U.S. dollar obligations that have been designated as hedges of net investments in foreign operations are recognized in accumulated other comprehensive income (loss) and reclassified to income in the same period when a foreign operation is sold and the gain or loss related to the sale is included in income. To the extent that any hedge is not fully effective at offsetting changes in the underlying hedged item, there could be a net earnings impact. The Company also uses derivatives to hedge economic exposures that do not receive hedge accounting under ASC 815. The underlying exposures for these hedges relate primarily to purchases of commodity-based components used in the Company's manufacturing processes, and the revaluation of certain foreign-currency-denominated assets and liabilities. Gains or losses from the ineffective portion of any hedge, as well as any gains or losses on derivative instruments not designated as hedges, are recognized in the income statement immediately. Counterparties to derivative arrangements are companies with high credit ratings, and the Company has bilateral collateral arrangements with them for which credit rating-based posting thresholds vary depending on the arrangement. If credit ratings on the Company's debt fall below preestablished levels, counterparties can require immediate full collateralization on all instruments in net liability positions. No collateral was posted with counterparties and none was held by the Company at year end. If contractual thresholds had been exceeded, the maximum collateral the Company could have been required to post was $8 . The Company can also demand full collateralization of instruments in net asset positions should any of the Company's counterparties' credit ratings fall below certain thresholds. Risk from credit loss when derivatives are in asset positions is not considered material. The Company has master netting arrangements in place with its counterparties that allow the offsetting of certain derivative-related amounts receivable and payable when settlement occurs in the same period. Accordingly, counterparty balances are netted in the consolidated balance sheet and are reported in other current assets or accrued expenses as appropriate, depending on positions with counterparties as of the balance sheet date. See Note 8.
Income Taxes	Income Taxes The provision for income taxes is based on pretax income reported in the consolidated statements of earnings and tax rates currently enacted in each jurisdiction. Certain income and expense items are recognized in different time periods for financial reporting and income tax filing purposes, and deferred income taxes are provided for the effect of temporary differences. The Company also provides for withholding taxes and any applicable U.S. income taxes on earnings intended to be repatriated from non-U.S. locations. No provision has been made for these taxes on approximately $4.0 billion of undistributed earnings of non-U.S. subsidiaries as of September 30, 2019 , as these earnings are considered indefinitely invested or otherwise retained for continuing international operations. Recognition of withholding taxes and any applicable U.S. income taxes on undistributed non-U.S. earnings would be triggered by a management decision to repatriate those earnings. Determination of the amount of taxes that might be paid on these undistributed earnings if eventually remitted is not practicable. See Note 14.
