Notes to Condensed Consolidated Financial Statements [Abstract]

Introduction of Notes to Condensed Consolidated Financial Statements

The Condensed Consolidated Financial Statements at March 31, 2012 and for the quarters ended March 31, 2012 and 2011 are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the results for the interim periods. The results reported in these Condensed Consolidated Financial Statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the financial statements and notes in our Annual Report to Shareowners (2011 Annual Report) incorporated by reference to our Annual Report on Form 10-K for calendar year 2011 (2011 Form 10-K).

Certain reclassifications have been made to the prior year amounts to conform to the current year presentation. On September 28, 2011, we announced a new organizational structure that allows us to better serve customers through greater integration across product lines. Effective January 1, 2012, we formed the UTC Climate, Controls & Security segment which combines the former Carrier and UTC Fire & Security segments. On March 14, 2012, the Board of Directors of the Company approved a plan for the divestiture of a number of non-core businesses. The results of operations including the expected loss and the related cash flows which result from these non-core businesses have been reclassified to Discontinued Operations in our Condensed Consolidated Statement of Comprehensive Income and Condensed Consolidated Statement of Cash Flows for all periods presented.

- Definition

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

Note 1: Acquisitions, Dispositions, Goodwill and Other Intangible Assets

3 Months Ended

Mar. 31, 2012

Notes to Condensed Consolidated Financial Statements [Abstract]

Note 1: Acquisitions, Dispositions, Goodwill and Other Intangible Assets

Business Acquisitions and Dispositions. During the quarter ended March 31, 2012, our investment in business acquisitions was $75 million (including debt assumed of $3 million), and consisted primarily of a number of small acquisitions in our commercial businesses.

On September 21, 2011, we announced an agreement to acquire Goodrich Corporation (Goodrich), a global supplier of systems and services to the aerospace and defense industry with 2011 sales of $8.1 billion. Goodrich products include aircraft nacelles and interior systems, actuation and landing systems, and electronic systems. Under the terms of the agreement, Goodrich shareholders will receive $127.50 in cash for each share of Goodrich common stock they own at the time of the closing of the transaction. This equates to a total estimated enterprise value of $18.4 billion, including $1.9 billion in net debt to be assumed. In March 2012, Goodrich received shareholder approval for the transaction. The transaction is subject to customary closing conditions, including regulatory approvals. We expect that this acquisition will close in mid-2012. Once the acquisition is complete, Goodrich and Hamilton Sundstrand will be combined to form a new segment named UTC Aerospace Systems. This segment and our Pratt & Whitney segment will be separately reportable segments although they will both be included within the UTC Propulsion & Aerospace Systems organizational structure. We expect the increased scale, financial strength and complementary products of the new combined business will strengthen our position in the aerospace and defense industry. Further, we expect that this acquisition will enhance our ability to support our customers with more integrated systems.

On October 12, 2011, Pratt & Whitney and Rolls-Royce plc (Rolls-Royce), participants in the IAE International Aero Engines AG (IAE) collaboration, announced an agreement to restructure their interests in IAE. Under the terms of the agreement, Rolls-Royce will sell its interests in IAE and license its V2500 intellectual property in IAE to Pratt & Whitney for $1.5 billion plus an agreed payment contingent on each hour flown by V2500-powered aircraft in service at the closing date during the fifteen year period following closing of the transaction. Consummation of this restructuring is subject to regulatory approvals and other closing conditions. Upon closing, we anticipate Pratt & Whitney will begin consolidating IAE. The acquisition of the additional interests in IAE and the intellectual property licenses will be reflected as intangible assets and amortized in relation to the economic benefits received over the projected remaining life of the V2500 program.

Goodwill. Changes in our goodwill balances during the quarter ended March 31, 2012 were as follows:

(Dollars in millions)		Balance as of January 1, 2012		Goodwill resulting from business combinations		Foreign currency translation and other		Balance as of March 31, 2012
Otis		$	1,516	$	6	$	13	$	1,535
UTC Climate, Controls & Security			9,758		21		34		9,813
Pratt & Whitney			1,223		-		(534)		689
Hamilton Sundstrand			4,475		-		(726)		3,749
Sikorsky			348		-		4		352

Total Segments			17,320		27		(1,209)		16,138
Eliminations and other			623		-		(592)		31

	Total	$	17,943	$	27	$	(1,801)	$	16,169

During the quarter ended March 31, 2012, goodwill balances decreased $1.8 billion, primarily as a result of the decision to divest a number of non-core businesses, which is reflected under “Foreign currency translation and other” in the table above. See Note 2 for further discussion.

Intangible Assets. Identifiable intangible assets are comprised of the following:

			March 31, 2012				December 31, 2011
(Dollars in millions)			Gross Amount		Accumulated Amortization		Gross Amount		Accumulated Amortization
Amortized:
	Service portfolios		$	2,088	$	(1,101)	$	2,036	$	(1,060)
	Patents and trademarks			412		(161)		463		(183)
	Other, principally customer relationships			3,235		(1,465)		3,329		(1,429)

				5,735		(2,727)		5,828		(2,672)

Unamortized:
	Trademarks and other			761				762

		Total	$	6,496	$	(2,727)	$	6,590	$	(2,672)

Amortization of intangible assets for the quarter ended March 31, 2012 was $99 million compared with $100 million for the same period of 2011. Average amortization of these intangible assets for 2012 through 2016 is expected to approximate $340 million per year.

Note 2: Discontinued Operations

Notes to Condensed Consolidated Financial Statements [Abstract]

Note 2: Discontinued Operations

On March 14, 2012, the Board of Directors of the Company approved a plan for the divestiture of a number of non-core businesses. Cash generated from these divestitures is intended to be used to repay a portion of the short-term debt we expect to incur as part of the financing for the proposed acquisition of Goodrich. The divestitures are expected to generate approximately $3 billion in cash, net of taxes. The results of operations including the net gain or loss and the related cash flows which result from these non-core businesses have been reclassified to Discontinued Operations on our Condensed Consolidated Statement of Comprehensive Income and Condensed Consolidated Statement of Cash Flows for all periods presented. The assets and liabilities of these non-core businesses have been reclassified to Discontinued Operations on our Condensed Consolidated Balance Sheet as of March 31, 2012. Cash flows from the operation of these discontinued businesses will continue until their disposals, most of which are expected to occur in the second half of 2012.

The planned divestitures are Hamilton Sundstrand's Industrial businesses, Pratt & Whitney Rocketdyne (“Rocketdyne”), and Clipper Windpower (“Clipper”). The operating results of Clipper had previously been reported within “Eliminations & other” in our segment disclosure. As a result of the decision to dispose of these businesses, the Company has recorded pre-tax goodwill impairment charges of approximately $360 million and $590 million related to Rocketdyne and Clipper, respectively, in discontinued operations during the first quarter of 2012. The goodwill impairment charges result from the decision to dispose of both Rocketdyne and Clipper within a relatively short period after acquiring the businesses. Consequently, there has not been sufficient opportunity for the long-term operations to recover the value implicit in goodwill at the initial date of acquisition. Fair value of these businesses has been estimated using information available in the marketplace as we market these businesses for sale.

The following summarized financial information related to these non-core businesses has been segregated from continuing operations and will be reported as discontinued operations through the dates of disposition:

			Quarter Ended March 31,
(Dollars in millions)			2012		2011
Discontinued Operations:
	Net sales		$	516	$	664

	Income from operations		$	41	$	90
	Income tax expense			(15)		(43)
		Income from operations, net of income taxes		26		47

	Loss on disposal			(961)		-
	Income tax benefit			84		-
	Net (loss) income on discontinued operations		$	(851)	$	47

The income tax benefit for the first quarter of 2012 includes approximately $235 million of unfavorable income tax adjustments related to the recognition of a deferred tax liability on the existing difference between the accounting versus tax gain on the planned dispositions of Hamilton Sundstrand's Industrial Businesses.

The assets and liabilities of discontinued operations on the Condensed Consolidated Balance Sheet as of March 31, 2012 are:

(Dollars in millions)

	Diluted weighted average number of shares outstanding		903.9		914.9

Earnings (Loss) Per Share of Common Stock - Basic:
	Net income from continuing operations	$	1.33	$	1.08
	Net (loss) income from discontinued operations		(0.96)		0.05
	Net income attributable to common shareowners		0.37		1.13

	Net (loss) income from discontinued operations		(0.94)		0.05
	Net income attributable to common shareowners		0.36		1.11

The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock appreciation rights and stock options, when the average market price of the common stock is lower than the exercise price of the related stock awards during the period. These outstanding stock awards are not included in the computation of diluted earnings per share because the effect would be anti-dilutive. For the quarters ended March 31, 2012 and 2011, there were no anti-dilutive stock awards excluded from the computation.

At March 31, 2012, we had revolving credit agreements with various banks permitting aggregate borrowings of up to $4.0 billion pursuant to a $2.0 billion revolving credit agreement and a $2.0 billion multicurrency revolving credit agreement, both of which expire in November 2016. As of March 31, 2012, there were no borrowings under either of these revolving credit agreements. The undrawn portions of our revolving credit agreements are also available to serve as backup facilities for the issuance of commercial paper. As of March 31, 2012, our maximum commercial paper borrowing authority as set by our Board of Directors was $4 billion. We generally use our commercial paper borrowings for general corporate purposes, including the funding of potential acquisitions and repurchases of our common stock.

On November 8, 2011, we entered into a bridge credit agreement with various financial institutions that provides for a $15 billion unsecured bridge loan facility, available to pay a portion of the cash consideration for the Goodrich acquisition, and to finance certain related transactions and pay related fees and expenses. Any funding under the bridge credit agreement would occur substantially concurrently with the consummation of the Goodrich acquisition, subject to customary conditions for acquisition financings of this type. Any loans made pursuant to the bridge credit agreement would mature on the date that is 364 days after the funding date.

On April 24, 2012, we entered into a term loan credit agreement with various financial institutions that provides for a $2 billion unsecured term loan facility, and which is available to pay a portion of the cash consideration for the Goodrich acquisition and finance certain related transactions and expenses. Any loan under the agreement would mature on December 31, 2012, and funding would occur shortly before consummation of the acquisition, subject to customary conditions for financings of this type. Funding would be conditioned on the substantially contemporaneous termination of the remaining commitments under our $15 billion bridge credit agreement executed on November 8, 2011.

Long-term debt consisted of the following:

* We may redeem some or all of these series of notes at any time at a redemption price in U.S. dollars equal to the greater of 100% of the principal amount outstanding of the applicable series of notes to be redeemed, or the sum of the present values of the remaining scheduled payments of principal and interest on the applicable series of notes to be redeemed. The discounts applied on such redemptions are based on a semiannual calculation at an adjusted treasury rate plus 10-50 basis points, depending on the particular series. The redemption price will also include interest accrued to the date of redemption on the principal balance of the notes being redeemed.

We have an existing universal shelf registration statement filed with the Securities and Exchange Commission (SEC) for an indeterminate amount of equity and debt securities for future issuance, subject to our internal limitations on the amount of equity and debt to be issued under this shelf registration statement.

Note 6: Income Taxes

3 Months Ended

Mar. 31, 2012

Notes to Condensed Consolidated Financial Statements [Abstract]

Note 6: Income Taxes

We conduct business globally and, as a result, UTC or one or more of our subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business we are subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Belgium, Canada, China, France, Germany, Hong Kong, Italy, Japan, South Korea, Singapore, Spain, the United Kingdom and the United States. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 1998.

In the ordinary course of business, there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management's evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, associated interest has also been recognized; interest accrued in relation to unrecognized tax benefits is recorded in interest expense. Penalties, if incurred, would be recognized as a component of income tax expense.

It is reasonably possible that over the next twelve months the amount of unrecognized tax benefits may change within a range of a net increase of $10 million to a net decrease of $120 million as a result of additional worldwide uncertain tax positions, the revaluation of current uncertain tax positions arising from developments in examinations, in appeals or in the courts, or the closure of tax statutes. A portion of this net reduction may impact the Company's 2012 or 2013 income tax expense. Not included in the range is €198 million (approximately $263 million) of tax benefits that we have claimed related to a 1998 German reorganization. These tax benefits are currently being reviewed by the German Tax Office in the course of an audit of tax years 1999 to 2000. In 2008 the German Federal Tax Court denied benefits to another taxpayer in a case involving a German tax law relevant to our reorganization. The determination of the German Federal Tax Court on this other matter was appealed to the European Court of Justice (ECJ) to determine if the underlying German tax law is violative of European Union (EU) principles. On September 17, 2009 the ECJ issued an opinion in this case that is generally favorable to the other taxpayer and referred the case back to the German Federal Tax Court for further consideration of certain related issues. In May 2010, the German Federal Tax Court released its decision, in which it resolved certain tax issues that may be relevant to our audit and remanded the case to a lower court for further development. After consideration of the ECJ decision and the latest German Federal Tax Court decision, we continue to believe that it is more likely than not that the relevant German tax law is violative of EU principles and we have not accrued tax expense for this matter. As we continue to monitor developments related to this matter, it may become necessary for us to accrue tax expense and related interest.

Tax years 2004 through 2008 are currently before the Appeals Division of the Internal Revenue Service (IRS) for resolution discussions regarding certain proposed tax adjustments with which the Company does not agree. The Company expects resolution discussions relating to the 2004 and 2005 tax years to be completed within the next 12 months. During the quarter, the Company recognized a non-cash gain of approximately $218 million, including a pre-tax interest adjustment of $15 million, as a result of the Examination Division of the IRS completing audit fieldwork for tax years 2006, 2007 and 2008. The IRS also commenced audit fieldwork for the 2009 and 2010 tax years.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Note 8: Restructuring and Other Costs

Note 8: Restructuring Costs

During the first quarter of 2012, we recorded net pre-tax restructuring costs in our business segments totaling $138 million for new and ongoing restructuring actions as follows:

(Dollars in millions)
Otis	$	28
UTC Climate, Controls & Security		35
Pratt & Whitney		37
Hamilton Sundstrand		2
Sikorsky		3
Eliminations and other		6
Restructuring costs recorded within continuing operations		111
Restructuring costs recorded within discontinued operations		27
Total	$	138

The net costs included $62 million recorded in cost of sales, $49 million in selling, general and administrative expenses, and $27 million in discontinued operations. As described below, these costs primarily relate to actions initiated during 2012 and 2011.

2012 Actions. During the first quarter of 2012, we initiated restructuring actions relating to ongoing cost reduction efforts, including workforce reductions and the consolidation of field operations. We recorded net pre-tax restructuring costs totaling $116 million, including $54 million in cost of sales, $35 million in selling, general and administrative expenses and $27 million in discontinued operations.

We expect the actions initiated in the first quarter of 2012 to result in net workforce reductions of approximately 1,700 hourly and salaried employees, the exiting of approximately 425,000 net square feet of facilities and the disposal of assets associated with exited facilities. As of March 31, 2012, we have completed net workforce reductions of approximately 350 employees. We are targeting the majority of the remaining workforce and all facility related cost reduction actions for completion during 2012 and 2013. No specific plans for significant other actions have been finalized at this time.

2011 Actions. During the first quarter of 2012, we recorded net pre-tax restructuring costs totaling $20 million for restructuring actions initiated in 2011, including $6 million in cost of sales and $14 million in selling, general and administrative expenses. The 2011 actions relate to ongoing cost reduction efforts, including workforce reductions and the consolidation of field operations.

As of March 31, 2012, we have completed net workforce reductions of approximately 3,500 employees of an expected 5,000 employees, and have exited approximately 100,000 net square feet of facilities of an expected 2 million net square feet. We are targeting the majority of the remaining workforce and facility related cost reduction actions for completion during 2012 and 2013.

Note 9: Financial Instruments

Notes to Condensed Consolidated Financial Statements [Abstract]

Note 9: Financial Instruments

We enter into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments under the Derivatives and Hedging Topic of the FASB Accounting Standards Codification (ASC) and those utilized as economic hedges. We operate internationally and, in the normal course of business, are exposed to fluctuations in interest rates, foreign exchange rates and commodity prices. These fluctuations can increase the costs of financing, investing and operating the business. We have used derivative instruments, including swaps, forward contracts and options to manage certain foreign currency, interest rate and commodity price exposures.

By their nature, all financial instruments involve market and credit risks. We enter into derivative and other financial instruments with major investment grade financial institutions and have policies to monitor the credit risk of those counterparties. We limit counterparty exposure and concentration of risk by diversifying counterparties. While there can be no assurance, we do not anticipate any material non-performance by any of these counterparties.

Foreign Currency Forward Contracts. We manage our foreign currency transaction risks to acceptable limits through the use of derivatives that hedge forecasted cash flows associated with foreign currency transaction exposures, which are accounted for as cash flow hedges, as we deem appropriate. To the extent these derivatives are effective in offsetting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria of the Derivatives and Hedging Topic of the FASB ASC, the changes in the derivatives' fair values are not included in current earnings but are included in “Accumulated other comprehensive loss.” These changes in fair value will subsequently be reclassified into earnings as a component of product sales or expenses, as applicable, when the forecasted transaction occurs. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded currently in earnings in the period in which it occurs.

To the extent the hedge accounting criteria are not met, the foreign currency forward contracts are utilized as economic hedges and changes in the fair value of these contracts are recorded currently in earnings in the period in which they occur. These include hedges that are used to reduce exchange rate risks arising from the change in fair value of certain foreign currency denominated assets and liabilities (e.g. payables, receivables) and other economic hedges where the hedge accounting criteria were not met.

The four quarter rolling average of the notional amount of foreign exchange contracts hedging foreign currency transactions was $11.0 billion and $10.4 billion at March 31, 2012 and December 31, 2011, respectively.

The following table summarizes the fair value of derivative instruments as of March 31, 2012 and December 31, 2011 which consist solely of foreign exchange contracts:

		March 31, 2012				December 31, 2011
(Dollars in millions)		Derivatives designated as hedging instruments		Derivatives not designated as hedging instruments		Derivatives designated as hedging instruments		Derivatives not designated as hedging instruments
Balance Sheet Asset Locations:
	Other assets, current	$	71	$	56	$	69	$	40
	Other assets		18		1		3		2
			89		57		72		42
Total Asset Derivative Contracts				$	146			$	114

Balance Sheet Liability Locations:
	Accrued liabilities	$	23	$	29	$	81	$	40
	Other long-term liabilities		12		2		43		1
			35		31		124		41
Total Liability Derivative Contracts				$	66			$	165

The impact from foreign exchange derivative instruments that qualified as cash flow hedges was as follows:

	Quarter Ended March 31,
(Dollars in millions)	2012		2011
Gain recorded in Accumulated other comprehensive loss	$	92	$	99
Gain reclassified from Accumulated other comprehensive loss into Product sales (effective portion)	$	11	$	43

Assuming current market conditions continue, a $10 million pre-tax loss is expected to be reclassified from Accumulated other comprehensive loss into Product sales to reflect the fixed prices obtained from foreign exchange hedging within the next 12 months. At March 31, 2012, all derivative contracts accounted for as cash flow hedges will mature by February 2014.

The effect on the Condensed Consolidated Statement of Comprehensive Income from foreign exchange contracts not designated as hedging instruments was as follows:

	Quarter Ended March 31,
(Dollars in millions)		2012		2011
Gain (loss) recognized in Other income, net	$	38	$	(4)

Fair Value Disclosure. As of January 1, 2012, we adopted the provisions of the FASB issued ASU No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” This ASU clarifies many of the existing concepts for measuring fair value and does not result in a change in our application of the Fair Value Measurements and Disclosures Topic of the FASB ASC. The guidance includes enhanced disclosure requirements about recurring Level 3 fair value measurements for each class of assets and liabilities measured at fair value in the balance sheet, which has no impact on our financial statements or disclosures as there are presently no Level 3 fair value measurements in our Condensed Consolidated Balance Sheet. This ASU also requires additional disclosures for items that are not measured at fair value in the balance sheet but for which the fair value is required to be disclosed.

Valuation Hierarchy. The following table provides the valuation hierarchy classification of assets and liabilities that are carried at fair value and measured on a recurring and nonrecurring basis in our Condensed Consolidated Balance Sheet as of March 31, 2012 and December 31, 2011:

(Dollars in millions)		Total Carrying Value at March 31, 2012		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Unobservable inputs (Level 3)
Recurring fair value measurements:
	Available-for-sale securities	$	897	$	897	$	-	$	-
	Derivative assets		146		-		146		-
	Derivative liabilities		(66)		-		(66)		-

Nonrecurring fair value measurements:
	Equity method investment		239		-		239		-
	Business dispositions		145		-		145		-
	During 2012, we recorded a non-cash net gain on nonrecurring fair value measurements of approximately $112 million within Other income, net from UTC Climate, Controls & Security’s ongoing portfolio transformation efforts including integrating the legacy UTC Fire & Security businesses with the legacy Carrier businesses. This net gain includes approximately $215 million from the sale of a controlling interest in a manufacturing and distribution joint venture in Asia, partially offset by $103 million of other-than-temporary impairment charges related to planned business dispositions.

(Dollars in millions)		Total Carrying Value at December 31, 2011		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Unobservable inputs (Level 3)
Recurring fair value measurements:
	Available-for-sale securities	$	926	$	926	$	-	$	-
	Derivative assets		114		-		114		-
	Derivative liabilities		(165)		-		(165)		-

Nonrecurring fair value measurements:
	Equity method investment		13		13		-		-
	During 2011, we recorded non-cash other-than-temporary impairment charges of $66 million within Other income, net on an equity investment. The impairment charge recorded on our investment was determined by comparing the carrying value of our investment to the closing market value of the shares on the dates the investment was deemed to be impaired.

Valuation Techniques. Our available-for-sale securities include equity investments that are traded in active markets, either domestically or internationally. They are measured at fair value using closing stock prices from active markets and are classified within Level 1 of the valuation hierarchy. Our derivative assets and liabilities are managed on the basis of net exposure to market and credit risks of each of the counterparties. The fair value for these derivative assets and liabilities is measured at the price that would be received on a net asset position for a particular risk or to transfer a net liability position for a particular risk in an orderly transaction between market participants at the measurement date. Our derivative assets and liabilities include foreign exchange contracts and commodity derivatives that are measured at fair value using internal models based on observable market inputs such as forward rates, interest rates, our own credit risk and our counterparties' credit risks. Based on these inputs, the derivative assets and liabilities are classified within Level 2 of the valuation hierarchy. Based on our continued ability to trade securities and enter into forward contracts, we consider the markets for our fair value instruments to be active. As of March 31, 2012, there were no significant transfers in and out of Level 1 and Level 2.

As of March 31, 2012, there has not been any significant impact to the fair value of our derivative liabilities due to our own credit risk. Similarly, there has not been any significant adverse impact to our derivative assets based on our evaluation of our counterparties' credit risks.

The following table provides carrying amounts and fair values of financial instruments that are not carried at fair value in our Condensed Consolidated Balance Sheet at March 31, 2012 and December 31, 2011:

	March 31, 2012				December 31, 2011
(Dollars in millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term receivables	$	275	$	270	$	283	$	276
Customer financing notes receivable		298		272		309		297

Long-term debt (excluding capitalized leases)		(9,514)		(11,745)		(9,575)		(11,639)

The following table provides the valuation hierarchy classification of assets and liabilities that are not carried at fair value in our Condensed Consolidated Balance Sheet as of March 31, 2012:

(Dollars in millions)	Total Fair Value at March 31, 2012		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Unobservable inputs (Level 3)
Recurring fair value measurements:

Customer financing notes receivable		272		-		272		-
Short-term borrowings		(221)		-		(20)		(201)
Long-term debt (excluding capitalized leases)		(11,745)		-		(11,690)		(55)

Valuation Techniques. Our long-term receivables and customer financing notes receivables include our commercial and aerospace long-term trade, government and other receivables, leases, and notes receivable. Our long-term receivables and customer financing notes receivables are measured at fair value using an income statement approach based on the present value of the contractual, promised or most likely cash flows discounted at observed or estimated market rate for comparable assets or liabilities that are traded in the market. Based on these inputs, long-term receivables and customer financing notes receivables are classified within Level 2 of the valuation hierarchy. Our short-term borrowings include commercial paper and other international credit facility agreements. Our long-term debt includes domestic and international notes. Commercial paper and domestic long-term notes are measured at fair values based on comparable transactions and current market interest rates quoted in active markets for similar assets, and are classified within Level 2 of the valuation hierarchy. Foreign short-term borrowings and foreign long-term notes are measured at fair value based on comparable transactions and rates calculated from the respective countries' yield curves. Based on these inputs, foreign borrowings and foreign long-term notes are classified within Level 3 of the valuation hierarchy. The fair values of Accounts receivable and Accounts payable approximate the carrying amounts due to the short-term maturities of these instruments.

We had outstanding commercial aerospace financing and other contractual commitments totaling approximately $2.2 billion and $2.3 billion at March 31, 2012 and December 31, 2011, respectively. Risks associated with changes in interest rates on these commitments are mitigated by the fact that interest rates are variable during the commitment term, and are set at the date of funding based on current market conditions, the fair value of the underlying collateral and the credit worthiness of the customers. As a result, the fair value of these financings is expected to equal the amounts funded. The fair value of the commitment itself is not readily determinable and is not considered significant.

Notes to Condensed Consolidated Financial Statements [Abstract]

Financing Receivables [Text Block]

A long-term or financing receivable represents a contractual right to receive money on demand or on fixed and determinable dates, including trade receivable balances with maturity dates greater than one year. Our long-term and financing receivables primarily represent balances related to the aerospace businesses such as long-term trade accounts receivable, leases, and notes receivable. We also have other long-term receivables in our commercial businesses; however, both the individual and aggregate amounts are not significant.

Our classes within aerospace long-term receivables are comprised of long-term trade accounts receivable and notes and leases receivable. Long-term trade accounts receivable represent amounts arising from the sale of goods and services with a contractual maturity date of greater than one year and are recognized as “Other assets” in our Condensed Consolidated Balance Sheet. Notes and leases receivable represent notes and lease receivables other than receivables related to operating leases, and are recognized as “Customer financing assets” in our Condensed Consolidated Balance Sheet. The following table summarizes the balance by class of aerospace long-term receivables as of March 31, 2012 and December 31, 2011:

(Dollars in millions)	March 31, 2012		December 31, 2011
Long-term trade accounts receivable	$	195	$	204
Notes and leases receivable		353		365
Total long-term receivables	$	548	$	569

Economic conditions and air travel influence the operating environment for most airlines, and the financial performance of our aerospace businesses is directly tied to the economic conditions of the commercial aerospace and defense industries. Additionally, the value of the collateral is also closely tied to commercial airline performance and may be subject to exposure of reduced valuation as a result of market declines. We determine a receivable is impaired when, based on current information and events, it is probable that we will be unable to collect amounts due according to the contractual terms of the receivable agreement. Factors considered in assessing collectability and risk include, but are not limited to, examination of credit quality indicators and other evaluation measures, underlying value of any collateral or security interests, significant past due balances, historical losses, and existing economic conditions.

Long-term receivables can be considered delinquent if payment has not been received in accordance with the underlying agreement. If determined delinquent, long-term trade accounts receivable and notes and leases receivable balances accruing interest may be placed on nonaccrual status. We record potential losses related to long-term receivables when identified. The reserve for credit losses on these receivables relates to specifically identified receivables that are evaluated individually for impairment. For notes and leases receivable, we determine a specific reserve for exposure based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral in connection with the evaluation of credit risk and collectability. For long-term trade accounts receivable, we evaluate credit risk and collectability individually to determine if an allowance is necessary. Uncollectible long-term receivables are written-off when collection of the indebtedness has been pursued for a reasonable period of time without collection; the customer is no longer in operation; or judgment has been levied, but the underlying assets are not adequate to satisfy the indebtedness. At both March 31, 2012 and December 31, 2011, we do not have any significant balances that are considered to be delinquent, on non-accrual status, past due 90 days or more, or considered to be impaired.

The following table provides the balance of aerospace long-term receivables and summarizes the associated changes in the reserve for estimated credit losses and exposure for the quarters ended March 31, 2012 and 2011, respectively:

(Dollars in millions)	2012		2011
Beginning balance of the reserve for credit losses and exposure as of January 1	$	70	$	42
Provision		-		-
Charge-offs		-		-
Recoveries		-		(9)
Other		(4)		-
Ending balance of the reserve for credit losses and exposure: individually evaluated for impairment as of March 31	$	66	$	33
Ending balance of long-term receivables: individually evaluated for impairment as of March 31	$	548	$	524

We determine credit ratings for each customer in the portfolio based upon public information and information obtained directly from our customers. We conduct a review of customer credit ratings, published historical credit default rates for different rating categories, and multiple third party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on these balances quarterly or when events and circumstances warrant. The credit ratings listed below range from “A” which indicates an extremely strong capacity to meet financial obligations and the receivable is either collateralized or uncollateralized, to “D” which indicates that payment is in default and the receivable is uncollateralized. There can be no assurance that actual results will not differ from estimates or that consideration of these factors in the future will not result in an increase or decrease to the allowance for credit losses on long-term receivables.

The following table summarizes the credit risk profile by creditworthiness category for aerospace long-term receivable balances at March 31, 2012 and December 31, 2011:

		March 31, 2012				December 31, 2011
(Dollars in millions)		Long-term trade accounts receivable		Notes and leases receivable		Long-term trade accounts receivable		Notes and leases receivable

Note 12: Guarantees

We extend a variety of financial, market value and product performance guarantees to third parties. There have been no material changes to guarantees outstanding since December 31, 2011.

The changes in the carrying amount of service and product warranties and product performance guarantees for the quarters ended March 31, 2012 and 2011 are as follows:

(Dollars in millions)	2012		2011
Balance as of January 1	$	1,468	$	1,136

Balance as of March 31	$	1,135	$	1,431

The decrease in the above table in “Other” during the quarter ended March 31, 2012 primarily reflects the impact of warranty reserves reclassified to Liabilities of Discontinued Operations, see Note 2 for further discussion. The increase reflected in “Other” during the quarter ended March 31, 2011 primarily reflected the impact of finalizing purchase accounting on the acquisition of Clipper.

Sales generated from engine programs, spare parts, and aftermarket business under collaboration arrangements are recorded as earned in our financial statements. Amounts attributable to our collaborative partners for their share of sales are recorded as an expense in our financial statements based upon the terms and nature of the arrangement. Costs associated with engine programs under collaborative arrangements are expensed as incurred. Under these arrangements, collaborators contribute their program share of engine parts, incur their own production costs and make certain payments to Pratt & Whitney for shared or joint program costs. The reimbursement of the collaborators' share of program costs is recorded as a reduction of the related expense item at that time. As of March 31, 2012, the collaborators' interests in all commercial engine programs ranged from 12% to 48%, inclusive of a portion of Pratt & Whitney's interests held by other participants. Pratt & Whitney is the principal participant in all existing collaborative arrangements. There are no individually significant collaborative arrangements and none of the partners exceed a 31% share in an individual program.

On October 12, 2011, Pratt & Whitney and Rolls-Royce announced an agreement to restructure their interests in IAE and to form a new joint venture to develop engines to power the next generation of mid-size aircraft that will replace the existing fleet of mid-size aircraft currently in service or in development. Consummation of each of these transactions is subject to regulatory approvals and other closing conditions. We expect the restructuring of the parties' interests in IAE to be completed in mid-2012. The closing of the new joint venture is also subject to the completion of the restructuring of the parties' interests in IAE and may take a substantially longer period of time to complete. See Note 1 for further discussion.

Notes to Condensed Consolidated Financial Statements [Abstract]

Note 14: Contingent Liabilities

Summarized below are the matters previously described in Note 17 of the Notes to the Consolidated Financial Statements in our 2011 Annual Report, incorporated by reference in our 2011 Form 10-K, updated as applicable.

Environmental. Our operations are subject to environmental regulation by federal, state and local authorities in the United States and regulatory authorities with jurisdiction over our foreign operations. We accrue for the costs of environmental investigatory, remediation, operating and maintenance costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. The most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site, including existing technology, current laws and regulations and prior remediation experience. Where no amount within a range of estimates is more likely, we accrue the minimum. For sites with multiple responsible parties, we consider our likely proportionate share of the anticipated remediation costs and the ability of the other parties to fulfill their obligations in establishing a provision for those costs. We discount liabilities with fixed or reliably determinable future cash payments. We do not reduce accrued environmental liabilities by potential insurance reimbursements. We periodically reassess these accrued amounts. We believe that the likelihood of incurring losses materially in excess of amounts accrued is remote.

Government. We are now, and believe that in light of the current U.S. government contracting environment we will continue to be, the subject of one or more U.S. government investigations. If we or one of our business units were charged with wrongdoing as a result of any of these investigations or other government investigations (including violations of certain environmental or export laws) the U.S. government could suspend us from bidding on or receiving awards of new U.S. government contracts pending the completion of legal proceedings. If convicted or found liable, the U.S. government could fine and debar us from new U.S. government contracting for a period generally not to exceed three years. The U.S. government could void any contracts found to be tainted by fraud.

Our contracts with the U.S. government are also subject to audits. Like many defense contractors, we have received audit reports, which recommend that certain contract prices should be reduced to comply with various government regulations. Some of these audit reports involve substantial amounts. We have made voluntary refunds in those cases we believe appropriate, have settled some allegations and continue to litigate certain other cases. In addition, we accrue for liabilities associated with those matters that are probable and can be reasonably estimated. The most likely settlement amount to be incurred is accrued based upon a range of estimates. Where no amount within a range of estimates is more likely, then we accrue the minimum amount.

As previously disclosed, the Department of Justice (DOJ) sued us in 1999 in the U.S. District Court for the Southern District of Ohio, claiming that Pratt & Whitney violated the civil False Claims Act and common law. This lawsuit relates to the “Fighter Engine Competition” between Pratt & Whitney's F100 engine and General Electric's F110 engine. The DOJ alleges that the government overpaid for F100 engines under contracts awarded by the U.S. Air Force in fiscal years 1985 through 1990 because Pratt & Whitney inflated its estimated costs for some purchased parts and withheld data that would have revealed the overstatements. At trial of this matter, completed in December 2004, the government claimed Pratt & Whitney's liability to be $624 million. On August 1, 2008, the trial court judge held that the Air Force had not suffered any actual damages because Pratt & Whitney had made significant price concessions. However, the trial court judge found that Pratt & Whitney violated the False Claims Act due to inaccurate statements contained in the 1983 offer. In the absence of actual damages, the trial court judge awarded the DOJ the maximum civil penalty of $7.09 million, or $10,000 for each of the 709 invoices Pratt & Whitney submitted in 1989 and later under the contracts. In September 2008, both the DOJ and UTC appealed the decision to the Sixth Circuit Court of Appeals. In November 2010, the Sixth Circuit affirmed Pratt & Whitney's liability under the False Claims Act and remanded the case to the U.S. District Court for further proceedings on the question of damages. Should the government ultimately prevail, the outcome of this matter could result in a material effect on our results of operations in the period in which a liability would be recognized or cash flows for the period in which damages would be paid.

As previously disclosed, in December 2008, the Department of Defense (DOD) issued a contract claim against Sikorsky to recover overpayments the DOD alleges it has incurred since January 2003 in connection with cost accounting changes approved by the DOD and implemented by Sikorsky in 1999 and 2006. These changes relate to the calculation of material overhead rates in government contracts. The DOD claims that Sikorsky's liability is approximately $92 million (including interest through March 2012). We believe this claim is without merit and Sikorsky filed an appeal in December 2009 with the U.S. Court of Federal Claims, which is pending. We do not believe the resolution of this matter will have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

A significant portion of our activities are subject to export control regulation by the U.S. Department of State (State Department) under the U.S. Arms Export Control Act and International Traffic in Arms Regulations (ITAR). From time to time, we identify, investigate, remediate and voluntarily disclose to the State Department's Office of Defense Trade Controls Compliance (DTCC) potential violations of the ITAR. DTCC administers the State Department's authority under the ITAR to impose civil penalties and other administrative sanctions for violations, including debarment from engaging in the export of defense articles or defense services. Most of our voluntary disclosures are resolved without the imposition of penalties or other sanctions. However, as previously disclosed, in November 2011, DTCC informed us that it considers certain of our voluntary disclosures filed since 2005 to reflect deficiencies warranting penalties and sanctions. We are currently in discussions with DTCC to reach a consent agreement, which we anticipate will provide for a payment by the Company to the State Department and commitments regarding additional remedial compliance efforts.

The voluntary disclosures that we anticipate will be addressed in the consent agreement currently under discussion include 2006 and 2007 disclosures regarding the export by Hamilton Sundstrand to Pratt & Whitney Canada (P&WC) of certain modifications to dual-use electronic engine control software, and the re-export by P&WC of those software modifications and subsequent P&WC-developed patches to China during the period 2002-2004 for use in the development of the Z-10 Chinese military helicopter. As previously disclosed, the DOJ has also separately conducted a criminal investigation of the matters addressed in these disclosures, as well as the accuracy and adequacy of the disclosures. We have been cooperating with the DOJ's investigation. Since November 2011, we have been in discussions with the DOJ to resolve this matter.

We continue to evaluate the range of possible outcomes of these separate but related export compliance matters and have recognized a potential liability at March 31, 2012 of $55 million. We currently expect resolution of these matters to occur in the first half of 2012. We do not believe the ultimate resolution of these matters, individually or collectively, will have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

Other. We extend performance and operating cost guarantees beyond our normal warranty and service policies for extended periods on some of our products. We have accrued our estimate of the liability that may result under these guarantees and for service costs that are probable and can be reasonably estimated.

During the first quarter of 2012, we identified the potential for additional remediation costs associated with certain components within the main shaft of wind turbines previously installed by our Clipper business. We are currently researching the cause of the underlying quality issues and have not yet identified the final corrective remediation actions. We are unable to determine a reasonably possible remediation cost estimate at this time. Depending upon the nature of the remediation actions required and the number of installed turbines that may be affected, the outcome of this matter could result in a material effect on our results of operations in the period in which a warranty liability would be recognized or cash flows for the period in which warranty remediation is performed.

We are involved in a number of other legal proceedings, investigations and other contingency matters, including government audit matters, environmental investigatory, remediation, operating and maintenance costs, performance guarantees, self-insurance programs and matters arising out of the normal course of business. We are also subject to a number of routine lawsuits, investigations and claims (some of which involve substantial amounts) arising out of the ordinary course of our business. Many of these proceedings are at preliminary stages, and many of these cases seek an indeterminate amount of damages. We regularly evaluate the status of legal proceedings in which we are involved, to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred and determine if accruals and related disclosures are appropriate. The Company has established reserves for several hundred of its legal proceedings and other matters. We accrue contingencies based upon a range of possible outcomes. If no amount within this range is a better estimate than any other, then we accrue the minimum amount. With respect to any additional losses that may be incurred in excess of those accrued, either they are considered not material for disclosure or we do not believe that a range of reasonably possible losses (defined by the relevant accounting literature to include all potential losses other than those deemed “remote”) can be determined. We do not believe that these matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition.

All forward-looking statements concerning the possible or anticipated outcome of environmental, investigatory, litigation proceedings and other contingency matters involve risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the forward-looking statements. For further information as to these risks and uncertainties, see “Cautionary Note Concerning Factors That May Affect Future Results” and Part II, Item 1A, “Risk Factors” in this Form 10-Q.

Notes to Condensed Consolidated Financial Statements [Abstract]

Note 15: Segment Financial Data

Our operations are classified into five principal segments: Otis, UTC Climate, Controls & Security, Pratt & Whitney, Hamilton Sundstrand and Sikorsky. The segments are generally based on the management structure of the businesses and the grouping of similar operating companies, where each management organization has general operating autonomy over diversified products and services. On September 28, 2011, we announced a new organizational structure that allows us to better serve customers through greater integration across product lines. Effective January 1, 2012, we formed the UTC Climate, Controls & Security segment which combines the former Carrier and UTC Fire & Security segments.

Results for the quarters ended March 31, 2012 and 2011 are as follows:

	Net Sales				Operating Profits				Operating Profit Margins
(Dollars in millions)	2012		2011		2012		2011		2012	2011

Note 16: Accounting Pronouncements

In December 2011, the FASB issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” This ASU is intended to enhance a financial statement user's ability to understand the effects of netting arrangements on an entity's financial statements, including financial instruments and derivative instruments that are either offset or subject to an enforceable master netting or similar arrangement. The scope of this ASU includes derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. This ASU includes enhanced disclosure requirements, including both gross and net information about instruments and transactions eligible for offset or subject to an agreement similar to a master netting arrangement. The provisions of this ASU will be applied retrospectively for interim and annual periods beginning on or after January 1, 2013. We are currently evaluating the impact of this new ASU.

- Definition

Tabular disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

Financing Receivable, Credit Quality, Additional Information	We determine credit ratings for each customer in the portfolio based upon public information and information obtained directly from our customers. We conduct a review of customer credit ratings, published historical credit default rates for different rating categories, and multiple third party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on these balances quarterly or when events and circumstances warrant. The credit ratings listed below range from “A” which indicates an extremely strong capacity to meet financial obligations and the receivable is either collateralized or uncollateralized, to “D” which indicates that payment is in default and the receivable is uncollateralized.

Financing Receivable, Allowance for Credit Losses, Risk Characteristics	Economic conditions and air travel influence the operating environment for most airlines, and the financial performance of our aerospace businesses is directly tied to the economic conditions of the commercial aerospace and defense industries. Additionally, the value of the collateral is also closely tied to commercial airline performance and may be subject to exposure of reduced valuation as a result of market declines.
Financing Receivable, Allowance for Credit Losses, Factors that Influenced Management's Judgment	Factors considered in assessing collectability and risk include, but are not limited to, examination of credit quality indicators and other evaluation measures, underlying value of any collateral or security interests, significant past due balances, historical losses, and existing economic conditions.
Financing Receivable, Allowance for Credit Losses, Policy for Uncollectible Amounts	Uncollectible long-term receivables are written-off when collection of the indebtedness has been pursued for a reasonable period of time without collection; the customer is no longer in operation; or judgment has been levied, but the underlying assets are not adequate to satisfy the indebtedness.

Department of Justice Lawsuit Against Pratt and Whitney [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	1999
Loss Contingency Allegations	As previously disclosed, the Department of Justice (DOJ) sued us in 1999 in the U.S. District Court for the Southern District of Ohio, claiming that Pratt & Whitney violated the civil False Claims Act and common law. This lawsuit relates to the “Fighter Engine Competition” between Pratt & Whitney’s F100 engine and General Electric’s F110 engine. The DOJ alleges that the government overpaid for F100 engines under contracts awarded by the U.S. Air Force in fiscal years 1985 through 1990 because Pratt & Whitney inflated its estimated costs for some purchased parts and withheld data that would have revealed the overstatements. At trial of this matter, completed in December 2004, the government claimed Pratt & Whitney’s liability to be $624 million.
Loss Contingency Period Of Occurrence	fiscal years 1985 through 1990
Loss Contingency Damages Sought	$624 million
Loss Contingency Actions Taken By Court Arbitrator Or Mediator	On August 1, 2008, the trial court judge held that the Air Force had not suffered any actual damages because Pratt & Whitney had made significant price concessions. However, the trial court judge found that Pratt & Whitney violated the False Claims Act due to inaccurate statements contained in the 1983 offer. In the absence of actual damages, the trial court judge awarded the DOJ the maximum civil penalty of $7.09 million, or $10,000 for each of the 709 invoices Pratt & Whitney submitted in 1989 and later under the contracts. In September 2008, both the DOJ and UTC appealed the decision to the Sixth Circuit Court of Appeals. In November 2010, the Sixth Circuit affirmed Pratt & Whitney’s liability under the False Claims Act and remanded the case to the U.S. District Court for further proceedings on the question of damages.
Loss Contingency Actions Taken By Plaintiff And Defendant	In September 2008, both the DOJ and UTC appealed the decision to the Sixth Circuit Court of Appeals.
Department of Defense Contract Claim Against Sikorsky [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	December 2008
Loss Contingency Allegations	As previously disclosed, in December 2008, the Department of Defense (DOD) issued a contract claim against Sikorsky to recover overpayments the DOD alleges it has incurred since January 2003 in connection with cost accounting changes approved by the DOD and implemented by Sikorsky in 1999 and 2006. These changes relate to the calculation of material overhead rates in government contracts. The DOD claims that Sikorsky’s liability is approximately $92 million (including interest through March 2012).
Loss Contingency Damages Sought	$92 million (including interest through March 2012)
Loss Contingency Actions Taken By Defendant	We believe this claim is without merit and Sikorsky filed an appeal in December 2009 with the U.S. Court of Federal Claims, which is pending.

As previously disclosed, the DOJ has also separately conducted a criminal investigation of the matters addressed in these disclosures, as well as the accuracy and adequacy of the disclosures.
Loss Contingency Period Of Occurrence	2002-2004
Loss Contingency Actions Taken By Defendant	We have been cooperating with the DOJ’s investigation. Since November 2011, we have been in discussions with the DOJ to resolve this matter.
