Summary Of Significant Accounting Policies	12 Months Ended
	Sep. 30, 2013
Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICES
	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. See Note 3 for operating results that have been classified as discontinued operations in 2011.
	Effective October 1, 2012, the Company adopted updates to ASC 220, Comprehensive Income, and now presents comprehensive income in a separate financial statement immediately following the statement of earnings. This update does not change the items reported in other comprehensive income or when those items should be reclassified into earnings. Effective first quarter 2014, additional disclosures will be required for comprehensive income, including presenting reclassifications out of accumulated other comprehensive income by income statement line item.
	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.
	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 or market. The majority of inventory is valued based on standard costs that 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 fiscal year. The annual effect of resetting standards plus any operating variances incurred during each period are allocated between inventories and cost of sales. Following are the components of inventory as of September 30:
		2012		2013
	Finished products	$	747	678
	Raw materials and work in process	1,378		1,217
	Total inventories	$	2,125	1,895
	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 the 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 Emerson'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 expected future undiscounted cash flows of the related assets is less than their carrying values. The components of property, plant and equipment as of September 30 follow:
		2012		2013
	Land	$	268	278
	Buildings	2,103		1,965
	Machinery and equipment	6,193		6,440
	Construction in progress	370		409
	Property, plant and equipment, at cost	8,934		9,092
	Less: Accumulated depreciation	5,425		5,487
	Property, plant and equipment, net	$	3,509	3,605
	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 primarily under an income approach that discounts estimated future cash flows using risk-adjusted interest rates.
	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 6.
	Product Warranty
	Warranties vary by product line and are competitive for the markets in which the Company operates. Warranties generally extend for a period of one to two years from the date of sale or installation. Provisions for warranty are determined primarily based on historical warranty cost as a percentage of sales or a fixed amount per unit sold based on failure rates, adjusted for specific problems that may arise. Product warranty expense is less than one percent of sales.
	Revenue Recognition
	The Company recognizes nearly all of its revenues through the sale of manufactured products and records the sale when products are shipped or delivered, and title passes to the customer with collection reasonably assured. In certain limited circumstances, revenue is recognized using the percentage-of-completion method as performance occurs, or in accordance with ASC 985-605 related to software. Management believes that all relevant criteria and conditions are considered when recognizing revenue.
	Sales arrangements sometimes involve delivering multiple elements, including services such as installation. In these instances, the revenue assigned to each element is based on vendor-specific objective evidence, third-party evidence or a management estimate of the relative selling price. Revenue is recognized individually for delivered elements only if they have value to the customer on a stand-alone basis and the performance of the undelivered items is probable and substantially in the Company's control, or the undelivered elements are inconsequential or perfunctory and there are no unsatisfied contingencies related to payment. Approximately ten percent of the Company's revenues arise from qualifying sales arrangements that include the delivery of multiple elements, principally in the Network Power and Process Management segments. The vast majority of these deliverables are tangible products, with a small portion attributable to installation, service or maintenance. Generally, contract duration is short-term and cancellation, termination or refund provisions apply only in the event of contract breach, and have historically not been invoked.
	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. Emerson's foreign currency exposures primarily relate to transactions denominated in euros, Mexican pesos, Canadian dollars and Chinese renminbi. 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. 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 and amounts currently hedged beyond 18 months are not significant.
	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 deferral 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 non-U.S. dollar net asset exposures are reported in equity. 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 deferral 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. Similarly, Emerson can 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. Net values of contracts are reported in other current assets or accrued expenses as appropriate depending on positions with counterparties as of the balance sheet date. See Note 7.
	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 U.S. federal income taxes, net of available foreign tax credits, on earnings intended to be repatriated from non-U.S. locations. No provision has been made for U.S. income taxes on approximately $7.1 billion of undistributed earnings of non-U.S. subsidiaries as of September 30, 2013, as these earnings are considered permanently invested or otherwise indefinitely retained for continuing international operations. Recognition of U.S. taxes on undistributed non-U.S. earnings would be triggered by a management decision to repatriate those earnings, although there is no current intention to do so. Determination of the amount of taxes that might be paid on these undistributed earnings if eventually remitted is not practicable. See Note 13.
	Comprehensive Income
	Comprehensive income is primarily composed of net earnings plus changes in foreign currency translation, pension and postretirement adjustments, and the effective portion of changes in the fair value of cash flow hedges. Accumulated other comprehensive income, net of tax (a component of equity), consists of foreign currency translation credits of $504 and $466, deferred pension and postretirement charges of $692 and $1,213 and cash flow hedges and other charges of $1 and credits of $16, respectively, at September 30, 2013 and 2012. Accumulated other comprehensive income attributable to noncontrolling interests in subsidiaries consists primarily of earnings, and changes in foreign currency translation.

	WEIGHTED-AVERAGE COMMON SHARES
	Basic earnings per common share consider only the weighted-average of common shares outstanding while diluted earnings per common share also consider the dilutive effects of stock options and incentive shares. Options to purchase approximately 0.6 million, 7.7 million and 4.6 million shares of common stock were excluded from the computation of diluted earnings per share in 2013, 2012 and 2011, respectively, as the effect would have been antidilutive. Earnings allocated to participating securities were inconsequential for all years presented. Reconciliations of weighted-average shares for basic and diluted earnings per common share follow (shares in millions):

	ACQUISITIONS AND DIVESTITURES
	On July 31, 2013, the Company entered into an agreement to sell a 51 percent controlling interest in the embedded computing and power business for which it will receive approximately $300 in cash from the acquirer and through borrowing by a new entity which will include this business. The transaction is expected to close before the end of calendar 2013 pending regulatory approvals. Embedded computing and power had 2013 revenue of $1.2 billion and earnings before taxes of $44 which are included in the Network Power segment. Sales and earnings for embedded computing and power will continue to be reported in the Company's consolidated results until completion of the transaction. As the Company will retain a noncontrolling interest in this business, it will not be classified as discontinued operations and will be accounted for on the equity basis upon completion. Transaction fair value was determined based on anticipated cash proceeds and the estimated value of the retained interest using a Level 3 market approach (option pricing model). Assets and liabilities for embedded computing and power are classified as held-for-sale in the consolidated balance sheet at September 30, 2013 as follows: other current assets, $408 (accounts receivable, inventories, other); other assets, $190 (property plant and equipment, goodwill, other noncurrent assets); accrued expenses, $272 (accounts payable and other current liabilities); and other liabilities, $20. The Company recorded goodwill impairment charges in both 2013 and 2012, and income tax charges in 2013, related to this business. See Note 6 for information regarding impairment charges.
	In October 2013 (fiscal 2014), the Company acquired Virgo Valves and Controls, LTD, a leading manufacturer of ball valves and automation systems which will complement Process Management's existing final control business, and allow opportunities for additional growth in global oil and gas, mining and power end markets. Also in October 2013, the Company acquired Enardo LLC, a manufacturer of tank and terminal safety equipment used in the oil and gas, chemical and other industries which will complement Process Management's existing regulator technologies and extend the Company's expertise in both upstream and downstream markets. Total cash paid for both businesses was approximately $506, net of cash acquired. The Company also assumed $76 of debt. Combined annualized sales for Virgo and Enardo were over $300.
	The Company acquired one-hundred percent of Avtron Loadbank and a marine controls business during the second quarter of 2012. Avtron is a designer and manufacturer of high quality load banks and testing systems for power equipment industries and is included in the Network Power segment. The marine controls business supplies controls and software solutions for optimal operation of refrigerated sea containers and marine boilers and is included in the Climate Technologies segment. In addition, the Company acquired two smaller businesses during 2012 in the Process Management and Network Power segments. These small acquisitions were complementary to the existing business portfolios and none was individually significant. Total cash paid for all businesses was approximately $187, net of cash acquired of $5. Annualized sales for businesses acquired in 2012 were approximately $115. Goodwill of $94 ($36 of which is expected to be tax deductible) and identifiable intangible assets of $82, primarily customer relationships and patents and technology with a weighted-average life of approximately 9 years, were recognized from these transactions.
	In the fourth quarter of 2012, the Company sold its Knaack business unit for $114, resulting in an after-tax loss of $5 ($3 income tax benefit). Knaack had 2012 sales of $95 and net earnings of $7. Knaack, a leading provider of premium secure storage solutions for job sites and work vehicles, was previously reported in the Commercial & Residential Solutions business segment.
	The Company acquired several small businesses during 2011 which were complementary to the existing portfolios in mainly the Process Management and Climate Technologies segments. Total cash paid for all businesses was approximately $232, net of cash acquired of $2. Annualized sales for businesses acquired in 2011 were approximately $100. Goodwill of $125 (none of which is expected to be tax deductible) and identifiable intangible assets of $75, primarily customer relationships and patents and technology with a weighted-average life of approximately 12 years, were recognized from these transactions.
	In the fourth quarter of 2011, the Company sold its heating elements unit, which was previously included in the Commercial & Residential Solutions segment, for $73, resulting in an after-tax gain of $21 (net of $30 of income taxes). Heating elements had 2011 fourth quarter sales of $12 and net earnings of $1. Only the gain on divestiture and fourth quarter operating results for heating elements, plus the impact of finalizing the 2010 Motors and LANDesk divestitures, were classified as discontinued operations for 2011; prior fiscal 2011 quarters and prior year results of operations for heating elements were inconsequential and were not reclassified.
	The results of operations of the acquired businesses discussed above have been included in the Company's consolidated results of operations since the respective dates of acquisition.

Other decreased in 2013 primarily because of the receipt of an international research and development credit, lower foreign currency transaction losses and the comparative impact from the loss on the sale of the Knaack business in 2012. Other increased in 2012 due to higher foreign currency transaction losses and the loss on the Knaack sale. Gains, net decreased in 2013 due to $43 of dumping duties collected from U.S. Customs in 2012. Gains, net for 2011 included $15 related to the acquisition of full ownership of a Process Management joint venture in India.

Rationalization Of Operations	'
	RATIONALIZATION OF OPERATIONS
	Rationalization of operations expense reflects costs associated with the Company's efforts to continually improve operational efficiency and deploy assets globally to remain competitive on a worldwide basis. Each year the Company incurs costs to size its businesses to levels appropriate for current economic conditions and to improve its cost structure for future growth. Rationalization expenses result from numerous individual actions implemented across the Company's various operating units on an ongoing basis and include costs for moving facilities to best-cost locations, starting up plants after relocation or geographic expansion to serve local markets, exiting certain product lines, curtailing/downsizing operations because of changing economic conditions and other costs resulting from asset redeployment decisions. Shutdown costs include severance and benefits, stay bonuses, lease and contract termination costs and asset write-downs. In addition to the costs of moving fixed assets, start-up and moving costs include employee training and relocation. Vacant facility costs include security, maintenance, utilities and other costs.
	Rationalization expenses were $78, $119 and $81, respectively, for 2013, 2012 and 2011. The Company currently expects to incur 2014 rationalization expense of approximately $90, including costs to complete actions initiated before the end of 2013 and for actions anticipated to be approved and initiated during 2014.
	The change in the liability for the rationalization of operations during the years ended September 30 follows:
		2012		Expense	Paid/Utilized	2013

	Expenses incurred during 2013, 2012 and 2011 include actions to exit 13, 20 and 18 production, distribution or office facilities, and eliminate approximately 3,100, 2,700 and 2,800 positions, respectively, as well as costs related to facilities exited in previous periods. Costs have been concentrated in Network Power and Industrial Automation recently due to end market softness for these segments, including embedded computing and power, and acquisition integration activity in Network Power. The majority of costs have been incurred in Europe, North America and Asia.

Goodwill And Other Intangibles	'
	(6) GOODWILL AND OTHER INTANGIBLES
	Purchases of businesses are accounted for under the acquisition method, with substantially all goodwill assigned to the reporting unit that acquires the business. Under an impairment test performed annually, if the carrying amount of a reporting unit exceeds its estimated fair value, impairment is recognized to the extent that the carrying amount of the unit's goodwill exceeds the implied fair value of the goodwill. Fair values of reporting units are Level 3 measures, estimated primarily using an income approach that discounts future cash flows using risk-adjusted interest rates, and are subject to change due to changes in underlying economic conditions. See Note 3 for further discussion of changes in goodwill related to acquisitions and divestitures.
	The Company has faced persistent challenges in the embedded computing and power business due to protracted weak demand, structural industry developments and increased competition. These challenges, including weakness in telecommunication and mobile device markets, continued into 2013 and sales and earnings were both below expectations. In the third quarter of 2013, the Company recorded a noncash goodwill impairment charge of $503 ($475 after-tax, $0.65 per share). Income tax charges of $70 ($0.10 per share) for the anticipated repatriation of non-U.S. earnings from this business were also recorded in 2013. Additionally, in the fourth quarter the Company's goodwill impairment testing indicated that the carrying value of the connectivity solutions business in Network Power exceeded its fair value due to operating results not meeting forecasted expectations, resulting in a noncash, pretax charge to earnings of $25 ($21 after-tax, $0.03 per share). Management considered strategic alternatives for embedded computing and power, and on July 31, 2013 the Company entered into an agreement to sell a 51 percent controlling interest in this business. See Note 3 for additional information regarding the sale.
	In the fourth quarter of 2012, the Company incurred an impairment charge for the embedded computing and power business and the DC power systems business, after goodwill impairment testing revealed that the carrying values of these businesses exceeded the fair values. These businesses had been unable to meet operating objectives and the Company anticipated that growth in sales and earnings would be slower than previously expected given the end market circumstances noted previously. The carrying value of these businesses was reduced by a noncash, pretax charge to earnings totaling $592 ($528 after-tax, $0.72 per share). In 2011, the Company recorded a $19 ($0.03 per share) noncash, pretax impairment charge related to the Industrial Automation wind turbine pitch control business, reflecting a slowdown in investment for renewable energy.
	The change in the carrying value of goodwill by business segment follows. Cumulative pretax impairment charges in Network Power total $1.1 billion.

	Hedging Activities
	As of September 30, 2013, the notional amount of foreign currency hedge positions was approximately $1.5 billion, while commodity hedge contracts totaled approximately 62 million pounds ($175) of copper and aluminum. All derivatives receiving deferral accounting are cash flow hedges. The majority of hedging gains and losses deferred as of September 30, 2013 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 deferral accounting. Amounts included in earnings and other comprehensive income follow:
				Gain (Loss) to Earnings									Gain (Loss) to OCI
				2011			2012			2013			2011		2012	2013
		Location
	Commodity	Cost of sales		$	52		(42	)		(15	)		(58	)	43	(22	)
	Foreign currency	Sales, cost of sales		33			8			24			(14	)	58	4
	Foreign currency	Other deductions, net		9			45			(5	)
	Total			$	94		11			4			(72	)	101	(18	)
	Regardless of whether derivatives receive deferral 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 deferral accounting are highly effective and no amounts were excluded from the assessment of hedge effectiveness. Hedge ineffectiveness was immaterial in 2013, 2012 and 2011.
	Fair Value Measurement
	As of September 30, 2013, the fair value of commodity contracts and foreign currency contracts was reported in other current assets and accrued expenses. No collateral was posted with counterparties and none was held by the Company at year end. The maximum collateral that could have been required was $14. The estimated fair value of long-term debt was $4,727 and $5,088, respectively, as of September 30, 2013 and 2012, which exceeded the carrying value by $405 and $741, respectively. Valuations of derivative contract positions as of September 30 follow:

	Total retirement plans expense	$	190			223			296			103			112			108
	For defined contribution plans, the Company's obligation is to make cash contributions based on plan requirements, which are expensed as incurred. The Company has two small businesses that participate in multiemployer pension plans. Such participation is insignificant individually and in total. Cash contributed was inconsequential in all years. The Company could potentially incur immaterial liabilities upon withdrawal from these plans, although it has no intention to do so. Additionally, as with participation in any multiemployer plan, there is a theoretical but remote possibility the Company could incur material liabilities should all other participating employers be unable to fund their obligations.
	Reconciliations of the actuarial present value of the projected benefit obligations and of the fair value of plan assets for defined benefit pension plans follow:

	Approximately $171 of the $1,214 of pretax losses deferred in accumulated other comprehensive income at September 30, 2013, will be amortized to expense in 2014. As of September 30, 2013, retirement plans in total were underfunded by $121, which includes $368 of unfunded plans.
	As of the plans' September 30, 2013 and 2012 measurement dates, the total accumulated benefit obligation was $4,782 and $5,010, respectively. Also, as of the plans' respective measurement dates, the projected benefit obligation, accumulated benefit obligation and fair value of plan assets for retirement plans with accumulated benefit obligations in excess of plan assets were $978, $887 and $464, respectively, for 2013, and $4,763, $4,504 and $3,947, respectively, for 2012.
	Future benefit payments by U.S. plans are estimated to be $189 in 2014, $198 in 2015, $208 in 2016, $217 in 2017, $226 in 2018 and $1,256 in total over the five years 2019 through 2023. Based on foreign currency exchange rates as of September 30, 2013, future benefit payments by non-U.S. plans are estimated to be $51 in 2014, $51 in 2015, $55 in 2016, $56 in 2017, $58 in 2018 and $341 in total over the five years 2019 through 2023. The Company expects to contribute approximately $145 to its retirement plans in 2014.
	The weighted-average assumptions used in the valuation of pension benefits were as follows:
		U.S. Plans									Non-U.S. Plans
		2011			2012			2013			2011			2012			2013
	Net pension expense:
	Discount rate	5	%		4.75	%		4	%		4.6	%		5.2	%		4.1	%
	Expected return on plan assets	8	%		7.75	%		7.75	%		5.9	%		5.9	%		5.5	%

	Benefit obligations:
	Discount rate	4.75	%		4	%		4.75	%		5.2	%		4.1	%		4.2	%
	Rate of compensation increase	3	%		3.25	%		3.25	%		3.5	%		3.4	%		3.2	%
	The discount rate for the U.S. retirement plans was 4.75 percent as of September 30, 2013. An actuarially determined, company-specific yield curve is used to determine the discount rate. 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. Defined benefit pension plan expense for 2014 is expected to be approximately $155, versus $228 in 2013.
	The Company's asset allocations at September 30, 2013 and 2012, and weighted-average target allocations are
	as follows:
		U.S. Plans								Non-U.S. Plans

	The primary objective for the investment of plan assets is to secure participant retirement benefits while 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 strategy for equity assets is to minimize concentrations of risk by investing primarily in companies in a diversified mix of industries worldwide, while targeting neutrality in exposure to market capitalization levels, growth versus value profile, global versus regional markets, fund types and fund managers. 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. A small portion of U.S. plan assets is allocated to private equity partnerships and real asset fund investments for diversification, 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 plan assets as of September 30, organized by asset class and by the fair value hierarchy of ASC 820 as outlined in Note 1, follow:
		Level 1				Level 2			Level 3			Total			%

Asset Classes
U.S. Equities reflects companies domiciled in the U.S., including multinational companies. International Equities is comprised of companies domiciled in developed nations outside the U.S. Emerging Market Equities is comprised of companies domiciled in portions of Asia, Eastern Europe and Latin America. Corporate Bonds represents investment-grade debt of issuers primarily from the U.S. Government Bonds includes investment-grade instruments issued by federal, state and local governments, primarily in the U.S. High Yield Bonds includes 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 and exchange-traded real estate 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. Equity securities categorized as Level 2 assets are primarily nonexchange-traded commingled or collective funds where the underlying securities have observable prices available from active markets. Valuation is based on the net asset value of fund units held as derived from the fair value of the underlying assets. 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. Other Level 2 assets are valued based on a net asset value of fund units held, which is derived from either market-observed pricing for the underlying assets or broker/dealer quotation. 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, transferability restrictions, prevailing discount rates, volatilities, credit ratings and other factors. In the Other class, interests in mixed assets funds are Level 2, and U.S. life insurance contracts and non-U.S. general fund investments and insurance arrangements are Level 3.
A reconciliation of the change in value for Level 3 assets follows:
	2012				2013
Beginning balance	$	267			250
Gains (Losses) on assets held	9				25
Gains (Losses) on assets sold	(16		)		(22	)

	As of September 30, 2013 there were $169 of deferred actuarial gains in accumulated other comprehensive income, of which approximately $21 will be amortized into earnings in 2014. The assumed discount rates used in measuring the benefit obligations as of September 30, 2013, 2012 and 2011, were 4.00 percent, 3.25 percent and 4.25 percent, respectively. The assumed health care cost trend rate for 2014 is 7.0 percent, declining to 5.0 percent in 2018, and for 2013 was 7.5 percent, declining to 5.0 percent in 2018. A one-percentage-point increase or decrease in the assumed health care cost trend rate for each year would increase or decrease postretirement expense and the benefit obligation by inconsequential amounts. The Company estimates that future health care benefit payments will be $26 in 2014, $26 in 2015, $25 in 2016, $25 in 2017, $25 in 2018 and $113 in total over the five years 2019 through 2023.

	CONTINGENT LIABILITIES AND COMMITMENTS
	Emerson is a party to a number of pending legal proceedings and claims, including those involving general and product liability 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; the Company's experience in contesting, litigating and settling similar matters; and any related insurance coverage. Although it is not possible to predict the ultimate outcome of these matters, the Company historically has been 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, as examples, 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.
	On October 22, 2012, Invensys Systems, Inc. filed a suit for patent infringement against the Company and its wholly-owned indirect subsidiary, Micro Motion, Inc., in the Eastern District of Texas captioned Invensys Systems, Inc. v. Emerson Electric Co. and Micro Motion, Inc., USA. The complaint alleges infringement on Invensys patents by Micro Motion's Coriolis flowmeter "Enhanced Core Processors." The Invensys suit seeks unspecified damages for past infringement and an injunction preventing the Company and Micro Motion from engaging in future infringement. It is too early in the litigation to assess any potential financial impact. The Company and Micro Motion believe that the Invensys claims are without merit and that they have strong defenses to the claims, and intend to aggressively defend the suit.
	At September 30, 2013, 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.

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. Awards are granted at 100 percent of the closing market price of the Company's common stock on the date of grant. Awards made prior to 2011 were granted at 100 percent of the average of the high and low market prices 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, 2013, 19.1 million options were available for grant under the plans.
	Changes in shares subject to option during the year ended September 30, 2013 follow:
	(shares in thousands)	Average Exercise Price Per Share			Shares		Total		Average Remaining Life (Years)
							Intrinsic Value of Awards
	Beginning of year	$	44.75		14,603
	Options granted	$	51.7		639
	Options exercised	$	37.89		(3,377	)
	Options canceled	$	49.74		(191	)
	End of year	$	47.03		11,674		$	205	5.6
	Exercisable at year end	$	45.8		9,038		$	170	5
	The weighted-average grant date fair value per option was $10.12, $7.53 and $11.00 for 2013, 2012 and 2011, respectively. Cash received for option exercises was $104 in 2013, $42 in 2012 and $65 in 2011. The total intrinsic value of options exercised was $66, $38 and $49 in 2013, 2012 and 2011, respectively, and the actual tax benefit realized by the Company from tax deductions related to option exercises was $7, $11 and $16, 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 2013, 2012 and 2011 follow: risk-free interest rate, based on U.S. Treasury yields, 1.2 percent, 1.3 percent and 1.9 percent; dividend yield, 3.2 percent, 3.7 percent and 2.6 percent; and expected volatility, based on historical volatility, 28 percent, 27 percent and 25 percent. The expected life of each option awarded is 7 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. Distribution is primarily in shares of common stock and partially 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, 2013, 5,201,866 performance shares awarded primarily in 2010 were outstanding and contingent on the Company achieving its performance objectives and the provision of service by the employees. The objectives for these shares were met at the 93 percent level at the end of 2013, or 4,837,739 shares. Of these, 2,902,647 shares will be distributed in early 2014 while 1,935,092 shares remain subject to employees providing one additional year of service. Additionally, 5,118,500 performance shares awarded in 2013 are outstanding and contingent on the Company achieving its performance objectives through 2016 and the provision of service by the employees. As a result of the Company achieving its performance objectives at the 96 percent level at the end of 2010 for performance shares awarded primarily in 2007, and employees providing an additional year of service, rights to receive 4,777,248 common shares vested and were distributed to participants in 2011 as follows: 2,841,534 issued as shares, 1,661,045 withheld for income taxes and the value of 274,669 paid in cash.
	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 2013, 390,000 shares of restricted stock vested as a result of participants fulfilling the applicable service requirements. Consequently, 231,983 shares were issued while 158,017 shares were withheld for income taxes in accordance with minimum withholding requirements. As of September 30, 2013, there were 1,275,000 shares of unvested restricted stock outstanding.
	Changes in shares outstanding but not yet earned under the incentive shares plans during the year ended
	September 30, 2013 follow:
	(shares in thousands)	Shares		Average Grant Date
				Fair Value Per Share
	Beginning of year	6,799		$	39.55
	Granted	5,532		$	48.25
	Earned/vested	(390	)	$	33.15
	Canceled	(710	)	$	42.75
	End of year	11,231		$	43.86
	The total fair value of shares vested under incentive shares plans was $19, $15 and $276, respectively, in 2013, 2012 and 2011, of which $8, $6 and $113, respectively, was paid in cash, primarily for tax withholding. As of September 30, 2013, 5.0 million shares remained available for award under incentive shares plans.
	Total compensation expense for stock options and incentive shares was $221, $100 and $121, for 2013, 2012 and 2011, respectively. The increase from 2012 to 2013 reflects overlap of two performance shares programs during the year (2010 awards for performance through 2013 and 2013 awards for performance through 2016) and a higher stock price in the current year. The decrease from 2011 to 2012 reflects a stock option award in 2011 and no performance shares program overlap in 2012. Income tax benefits recognized in the income statement for these compensation arrangements during 2013, 2012 and 2011 were $68, $28 and $32, respectively. As of September 30, 2013, there was $316 of total unrecognized compensation expense related to unvested shares awarded under these plans, which is expected to be recognized over a weighted-average period of 2.7 years.
	In addition to the employee stock option and incentive shares plans, in 2013 the Company awarded 18,864 shares of restricted stock and 4,398 restricted stock units under the restricted stock plan for nonmanagement directors. As of September 30, 2013, 269,750 shares remained available for issuance under this plan.

Business Segments Information	'
	BUSINESS SEGMENTS INFORMATION
	The Company designs and supplies products and technology and delivers engineering services in a wide range of industrial, commercial and consumer end markets around the world. The business segments of the Company are organized primarily by the nature of the products and services they sell.
	The Process Management segment provides systems and software, measurement and analytical instrumentation, valves, actuators and regulators, and services and solutions, including digital plant architecture that allows communication of devices with centralized systems, to provide precision measurement, control, monitoring and asset optimization for plants that produce power or process fluids or items such as petroleum, chemicals, food and beverages, pulp and paper, pharmaceuticals, and municipal water supplies. The Industrial Automation segment provides low, medium and high voltage alternators and other power generation equipment, commercial and industrial motors and drives, power transmission and materials handling equipment, materials joining and precision cleaning products, fluid power and control mechanisms, and electrical distribution equipment which are used in a wide variety of manufacturing operations to provide integrated manufacturing solutions to customers. The Network Power segment designs, manufactures, installs and maintains power systems for telecommunications networks, data centers and other critical applications, including power conditioning and uninterruptible AC and DC power supplies, precision cooling systems, electrical switching equipment, integrated data center infrastructure monitoring, management systems, and embedded power supplies and computing systems. The Climate Technologies segment supplies compressors, temperature sensors and controls, thermostats, flow controls and remote monitoring technology and services to all elements of the climate control industry, including residential heating and cooling, commercial air conditioning, commercial and industrial refrigeration, and marine controls. The Commercial & Residential Solutions segment provides tools for professionals and homeowners, home and commercial storage systems, and appliance solutions. The principal distribution method for each segment is direct sales forces, although the Company also uses independent sales representatives and distributors. Due to its global presence, certain of the Company's international operations are subject to risks such as significant currency exchange rate fluctuations and restrictions on the movement of funds and potential nationalization of operations.
	The primary income measure used for assessing segment performance and making operating decisions is earnings before interest and income taxes. Intersegment selling prices approximate market prices. Accounting method differences between segment reporting and the consolidated financial statements are primarily management fees allocated to segments based on a percentage of sales and the accounting for pension and other retirement plans. Corporate and other includes goodwill impairment charges when applicable. Corporate assets are primarily comprised of cash and equivalents, investments and certain fixed assets. Summarized below is information about the Company's operations by business segment and by geography (also see Notes 3 through 6).

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Sep. 30, 2013
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. See Note 3 for operating results that have been classified as discontinued operations in 2011.
	Effective October 1, 2012, the Company adopted updates to ASC 220, Comprehensive Income, and now presents comprehensive income in a separate financial statement immediately following the statement of earnings. This update does not change the items reported in other comprehensive income or when those items should be reclassified into earnings. Effective first quarter 2014, additional disclosures will be required for comprehensive income, including presenting reclassifications out of accumulated other comprehensive income by income statement line item.
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.
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 or market. The majority of inventory is valued based on standard costs that 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 fiscal year. The annual effect of resetting standards plus any operating variances incurred during each period are allocated between inventories and cost of sales. Following are the components of inventory as of September 30:
		2012		2013
	Finished products	$	747	678
	Raw materials and work in process	1,378		1,217
	Total inventories	$	2,125	1,895
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 the 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 Emerson'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 expected future undiscounted cash flows of the related assets is less than their carrying values. The components of property, plant and equipment as of September 30 follow:
		2012		2013
	Land	$	268	278
	Buildings	2,103		1,965
	Machinery and equipment	6,193		6,440
	Construction in progress	370		409
	Property, plant and equipment, at cost	8,934		9,092
	Less: Accumulated depreciation	5,425		5,487
	Property, plant and equipment, net	$	3,509	3,605
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 primarily under an income approach that discounts estimated future cash flows using risk-adjusted interest rates.
	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 6.
Product Warranty	'
	Product Warranty
	Warranties vary by product line and are competitive for the markets in which the Company operates. Warranties generally extend for a period of one to two years from the date of sale or installation. Provisions for warranty are determined primarily based on historical warranty cost as a percentage of sales or a fixed amount per unit sold based on failure rates, adjusted for specific problems that may arise. Product warranty expense is less than one percent of sales.
Revenue Recognition	'
	Revenue Recognition
	The Company recognizes nearly all of its revenues through the sale of manufactured products and records the sale when products are shipped or delivered, and title passes to the customer with collection reasonably assured. In certain limited circumstances, revenue is recognized using the percentage-of-completion method as performance occurs, or in accordance with ASC 985-605 related to software. Management believes that all relevant criteria and conditions are considered when recognizing revenue.
	Sales arrangements sometimes involve delivering multiple elements, including services such as installation. In these instances, the revenue assigned to each element is based on vendor-specific objective evidence, third-party evidence or a management estimate of the relative selling price. Revenue is recognized individually for delivered elements only if they have value to the customer on a stand-alone basis and the performance of the undelivered items is probable and substantially in the Company's control, or the undelivered elements are inconsequential or perfunctory and there are no unsatisfied contingencies related to payment. Approximately ten percent of the Company's revenues arise from qualifying sales arrangements that include the delivery of multiple elements, principally in the Network Power and Process Management segments. The vast majority of these deliverables are tangible products, with a small portion attributable to installation, service or maintenance. Generally, contract duration is short-term and cancellation, termination or refund provisions apply only in the event of contract breach, and have historically not been invoked.
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. Emerson's foreign currency exposures primarily relate to transactions denominated in euros, Mexican pesos, Canadian dollars and Chinese renminbi. 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. 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 and amounts currently hedged beyond 18 months are not significant.
	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 deferral 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 non-U.S. dollar net asset exposures are reported in equity. 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 deferral 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. Similarly, Emerson can 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. Net values of contracts are reported in other current assets or accrued expenses as appropriate depending on positions with counterparties as of the balance sheet date. See Note 7.
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 U.S. federal income taxes, net of available foreign tax credits, on earnings intended to be repatriated from non-U.S. locations. No provision has been made for U.S. income taxes on approximately $7.1 billion of undistributed earnings of non-U.S. subsidiaries as of September 30, 2013, as these earnings are considered permanently invested or otherwise indefinitely retained for continuing international operations. Recognition of U.S. taxes on undistributed non-U.S. earnings would be triggered by a management decision to repatriate those earnings, although there is no current intention to do so. Determination of the amount of taxes that might be paid on these undistributed earnings if eventually remitted is not practicable. See Note 13.
Comprehensive Income	'
	Comprehensive Income
	Comprehensive income is primarily composed of net earnings plus changes in foreign currency translation, pension and postretirement adjustments, and the effective portion of changes in the fair value of cash flow hedges. Accumulated other comprehensive income, net of tax (a component of equity), consists of foreign currency translation credits of $504 and $466, deferred pension and postretirement charges of $692 and $1,213 and cash flow hedges and other charges of $1 and credits of $16, respectively, at September 30, 2013 and 2012. Accumulated other comprehensive income attributable to noncontrolling interests in subsidiaries consists primarily of earnings, and changes in foreign currency translation.
