Notes to Consolidated Financial Statements [Abstract]

Note 1: Summary of Accounting Principles

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from those estimates. 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 July 26, 2012 we acquired Goodrich Corporation (Goodrich). As a result of the acquisition, Goodrich became a wholly-owned subsidiary of UTC. The acquired Goodrich business and legacy Hamilton Sundstrand business have been combined to form a new segment named UTC Aerospace Systems. This segment and our Pratt & Whitney segment are separately reportable segments, although they are both included within the newly formed UTC Propulsion & Aerospace Systems organizational structure. In 2012, UTC's Board of Directors approved plans for the divestiture of a number of non-core businesses to help fund the Goodrich acquisition. The results of operations, including any realized gains and realized or expected losses on disposition and the related cash flows, which result from these non-core businesses have been reclassified to Discontinued Operations in our Consolidated Statement of Operations and Consolidated Statement of Cash Flows for all periods presented. See Note 3 for further discussion.

Consolidation. The Consolidated Financial Statements include the accounts of United Technologies Corporation (UTC) and its controlled subsidiaries. Intercompany transactions have been eliminated.

Cash and Cash Equivalents. Cash and cash equivalents includes cash on hand, demand deposits and short-term cash investments that are highly liquid in nature and have original maturities of three months or less.

On occasion, we are required to maintain cash deposits with certain banks with respect to contractual obligations related to acquisitions or divestitures or other legal obligations. As of December 31, 2012 and 2011, the amount of such restricted cash was approximately $35 million and $37 million, respectively and is included in Other assets, current.

Accounts Receivable. Current and long-term accounts receivable include retainage of $172 million and $154 million and unbilled receivables of $1,363 million and $1,060 million as of December 31, 2012 and 2011, respectively.

Retainage represents amounts that, pursuant to the applicable contract, are not due until project completion and acceptance by the customer. Unbilled receivables represent revenues that are not currently billable to the customer under the terms of the contract. These items are expected to be collected in the normal course of business. Long-term accounts receivable are included in Other assets in the Consolidated Balance Sheet.

Marketable Equity Securities. Equity securities that have a readily determinable fair value and that we do not intend to trade are classified as available-for-sale and carried at fair value. Unrealized holding gains and losses are recorded as a separate component of shareowners' equity, net of deferred income taxes.

Inventories and Contracts in Progress. Inventories and contracts in progress are stated at the lower of cost or estimated realizable value and are primarily based on first-in, first-out (FIFO) or average cost methods; however, certain UTC Aerospace Systems and UTC Climate, Controls & Security entities use the last-in, first-out (LIFO) method. If inventories that were valued using the LIFO method had been valued under the FIFO method, they would have been higher by $139 million and $144 million at December 31, 2012 and 2011, respectively.

Costs accumulated against specific contracts or orders are at actual cost. Inventory in excess of requirements for contracts and current or anticipated orders have been reserved as appropriate. Manufacturing costs are allocated to current production and firm contracts.

Fixed Assets. Fixed assets are stated at cost. Depreciation is recorded over the fixed assets' useful lives using the straight-line method.

Goodwill and Intangible Assets. Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill and intangible assets deemed to have indefinite lives are not amortized. Goodwill and indefinite-lived intangible assets are subject to annual impairment testing using the guidance and criteria described in the FASB ASC Topic “Intangibles – Goodwill and Other” . This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. During 2012 we early-adopted the FASB Accounting Standards Update (ASU) No. 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment” in connection with the performance of our annual goodwill and indefinite-lived intangible assets impairment test. This ASU intends to align impairment testing guidance among indefinite-lived asset categories. This ASU allows an assessment based on qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired prior to determining whether it is necessary to perform the quantitative impairment test in accordance with FASB ASC Subtopic 350-30, “Intangibles - Goodwill and Other - General Intangibles Other than Goodwill.” During 2012, we recorded pre-tax goodwill impairment charges of approximately $360 million and $590 million related to Pratt & Whitney Rocketdyne (Rocketdyne) and Clipper Windpower (Clipper), respectively. 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. During 2011 and 2010, we did not record any significant impairments to the carrying value of goodwill or indefinite-lived intangible assets.

Intangible assets consist of service portfolios, patents, trademarks/tradenames, customer relationships and other intangible assets including a collaboration asset established in connection with the restructuring of IAE International Aero Engines AG (IAE) as discussed further in Note 2. Also included within other intangible assets are commercial aerospace payments made to secure certain contractual rights to provide product on new aircraft platforms. Payments made on these contractual commitments are to be amortized as the related OEM and Aftermarket units are delivered.

Useful lives of finite-lived intangible assets are estimated based upon the nature of the intangible asset and the industry in which the intangible asset is used. These intangible assets are amortized based on the pattern in which the economic benefits of the intangible assets are consumed. For both our commercial aerospace collaboration assets and exclusivity arrangements, the pattern of economic benefit generally results in lower amortization during the development period with increasing amortization as programs enter full rate production and aftermarket cycles. If a pattern of economic benefit cannot be reliably determined, a straight-line amortization method is used. The range of estimated useful lives is as follows:

Collaboration asset 30 years

Customer relationships and related programs 2 to 32 years

Purchased service contracts 5 to 30 years

Patents & trademarks 3 to 40 years

Exclusivity assets 3 to 25 years

Other Long-Lived Assets. We evaluate the potential impairment of other long-lived assets when appropriate. If the carrying value of other long-lived assets exceeds the sum of the undiscounted expected future cash flows, the carrying value is written down to fair value. During the years ended December 31, 2012 and 2011, we had certain non-recurring fair value measurements resulting in impairment charges of $168 million and $66 million, respectively. See Note 14. Additionally, in 2012 we recorded pre-tax net asset impairment charges of approximately $179 million related to UTC Power in discontinued operations. The impairment charge at UTC Power results from the disposition of the business before the benefits of technology investments were fully realized.

Income Taxes. 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 expense has also been recognized. We recognize accrued interest related to unrecognized tax benefits in interest expense. Penalties, if incurred, would be recognized as a component of income tax expense.

Revenue Recognition. Sales under government and commercial fixed-price contracts and government fixed-price-incentive contracts are recorded at the time deliveries are made or, in some cases, on a percentage-of-completion basis. Sales under cost-reimbursement contracts are recorded as work is performed. Sales for elevators, escalators, installation and modernization contracts are accounted for under the percentage-of-completion method.

Losses, if any, on long-term contracts are provided for when anticipated. Loss provisions on original equipment contracts are recognized to the extent that estimated inventoriable manufacturing, engineering, product warranty and product performance guarantee costs, as appropriate, exceed the projected revenue from the products contemplated under the contractual arrangement. For new commitments, we generally record loss provisions at the earlier of contract announcement or contract signing except for certain requirements contracts under which losses are recorded upon receipt of the purchase order. For existing commitments, anticipated losses on contracts are recognized in the period in which losses become evident. Products contemplated under contractual arrangement include products purchased under contract and, in the large commercial engine and wheels and brakes businesses, future highly probable sales of replacement parts required by regulation that are expected to be purchased subsequently for incorporation into the original equipment. Revenue projections used in determining contract loss provisions are based upon estimates of the quantity, pricing and timing of future product deliveries. Losses are generally recognized on shipment to the extent that inventoriable manufacturing costs, estimated warranty costs and product performance guarantee costs, as appropriate, exceed revenue realized. Contract accounting requires estimates of future costs over the performance period of the contract as well as estimates of award fees and other sources of revenue. These estimates are subject to change and result in adjustments to margins on contracts in progress. The extent of progress toward completion on our long-term commercial aerospace equipment and helicopter contracts is measured using units of delivery. In addition, we use the cost-to-cost method for elevator and escalator sales, installation and modernization contracts in the commercial businesses. For long-term aftermarket contracts, revenue is recognized over the contract period in proportion to the costs expected to be incurred in performing services under the contract. We review our cost estimates on significant contracts on a quarterly basis, and for others, no less frequently than annually or when circumstances change and warrant a modification to a previous estimate. We record changes in contract estimates using the cumulative catch-up method in accordance with the Revenue Recognition Topic of the FASB ASC. In 2012, we recorded a $157 million charge on the CH-148 Canadian Maritime Helicopter program resulting from ongoing program delays.

Service sales, representing aftermarket repair and maintenance activities, are recognized over the contractual period or as services are performed. In the commercial businesses, revenue is generally recognized on a straight-line basis. In the aerospace businesses, revenue is generally recognized in proportion to cost.

Sales generated from engine programs, spare parts sales, and aftermarket business under collaboration arrangements are recorded as earned in our financial statements. Amounts attributable to our collaborators for their share of revenues 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 a collaborator's share of program costs is recorded as a reduction of the related expense item at that time.

UTC Climate, Controls & Security customarily offers its customers incentives to purchase products to ensure an adequate supply of its products in the distribution channels. The principal incentive program provides reimbursements to distributors for offering promotional pricing for our products. We account for incentive payments made as a reduction in sales.

Research and Development. Research and development costs not specifically covered by contracts and those related to the company sponsored share of research and development activity in connection with cost-sharing arrangements are charged to expense as incurred. Government research and development support, not associated with specific contracts, is recorded as a reduction to research and development expense in the period earned. Repayment, if any, is in the form of future royalties and is conditioned upon the achievement of certain financial targets including specific aircraft engine sales, total aircraft engine sales volume and total year-over-year sales growth of the entity receiving the government funding. Given the conditional and uncertain nature of any repayment obligations, royalty expense is typically recorded only upon engine shipment or is otherwise accrued monthly based upon the forecasted impact for the current year. The cumulative funding received under existing relationships has been approximately $2.0 billion of which approximately $450 million has been repaid to date in the form of royalties.

Research and development costs incurred under contracts with customers are included as a contract cost and reported as a component of cost of products sold when revenue from such contracts is recognized. Research and development costs in excess of contractual consideration is expensed as incurred.

Foreign Exchange and Hedging Activity. We conduct business in many different currencies and, accordingly, are subject to the inherent risks associated with foreign exchange rate movements. The financial position and results of operations of substantially all of our foreign subsidiaries are measured using the local currency as the functional currency. Foreign currency denominated assets and liabilities are translated into U.S. Dollars at the exchange rates existing at the respective balance sheet dates, and income and expense items are translated at the average exchange rates during the respective periods. The aggregate effects of translating the balance sheets of these subsidiaries are deferred as a separate component of shareowners' equity.

We have used derivative instruments, including swaps, forward contracts and options, to help manage certain foreign currency, interest rate and commodity price exposures. Derivative instruments are viewed as risk management tools by us and are not used for trading or speculative purposes. Derivatives used for hedging purposes may be designated and effective as a hedge of the identified risk exposure at the inception of the contract.

All derivative instruments are recorded on the balance sheet at fair value. Derivatives used to hedge foreign-currency-denominated balance sheet items are reported directly in earnings along with offsetting transaction gains and losses on the items being hedged. Derivatives used to hedge forecasted cash flows associated with foreign currency commitments or forecasted commodity purchases may be accounted for as cash flow hedges, as deemed appropriate. Gains and losses on derivatives designated as cash flow hedges are recorded in other comprehensive income and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions. The ineffective portion of all hedges, if any, is recognized currently in earnings.

Additional information pertaining to foreign currency forward contracts is included in Note 14.

Environmental. Environmental investigatory, remediation, operating and maintenance costs are accrued 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, the minimum is accrued. 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. Liabilities with fixed or reliably determinable future cash payments are discounted. Accrued environmental liabilities are not reduced by potential insurance reimbursements.

Asset Retirement Obligations. We record the fair value of legal obligations associated with the retirement of tangible long-lived assets in the period in which it is determined to exist, if a reasonable estimate of fair value can be made. Upon initial recognition of a liability, we capitalize the cost of the asset retirement obligation by increasing the carrying amount of the related long-lived asset. Over time, the liability is increased for changes in its present value and the capitalized cost is depreciated over the useful life of the related asset. We have determined that conditional legal obligations exist for certain of our worldwide owned and leased facilities related primarily to building materials. As of December 31, 2012 and 2011, the outstanding liability for asset retirement obligations was $174 million and $164 million, respectively.

Pension and Postretirement Obligations. Guidance under the FASB ASC Topic Compensation – Retirement Benefits requires balance sheet recognition of the overfunded or underfunded status of pension and postretirement benefit plans. Under this guidance, actuarial gains and losses, prior service costs or credits, and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized in other comprehensive income, net of tax effects, until they are amortized as a component of net periodic benefit cost.

Notes to Consolidated Financial Statements [Abstract]

Note 2: Business Acquisitions, Dispositions, Goodwill and Intangible Assets

Business Acquisitions and Dispositions. Our investments in businesses in 2012, 2011 and 2010 totaled $18.6 billion (including debt assumed of $2.6 billion), $372 million (including debt assumed of $15 million) and $2.8 billion (including debt assumed of $39 million), respectively.

On July 26, 2012, we completed the acquisition of 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, actuation, landing and electronic systems. Under the terms of the agreement, Goodrich shareholders received $127.50 in cash for each share of Goodrich common stock they owned on July 26, 2012. This equated to a total enterprise value of $18.3 billion, including $1.9 billion in net debt assumed. The acquired Goodrich businesses were combined with the legacy Hamilton Sundstrand businesses to form the new UTC Aerospace Systems segment. The Goodrich acquisition and the formation of UTC Aerospace Systems provide increased scale, financial strength and complementary product offerings, allowing us to significantly strengthen our position in the aerospace and defense industry, create aftermarket efficiencies for our customers, accelerate our ability to drive innovation within the aerospace industry, and enhance our ability to support our customers with more integrated systems. This acquisition, coupled with our acquisition of an additional interest in IAE, as discussed below, further advances UTC's strategy of focusing on our core businesses.

To finance the cash consideration for the Goodrich acquisition and pay related fees, expenses and other amounts due and payable, we utilized the previously disclosed net proceeds of approximately $9.6 billion from the $9.8 billion of long-term notes issued on June 1, 2012, the net proceeds of approximately $1.1 billion from the equity units issued on June 18, 2012, $3.2 billion from the issuance of commercial paper during July 2012, and $2.0 billion of proceeds borrowed under our April 24, 2012 term loan credit agreement. For the remainder of the cash consideration, we utilized approximately $0.5 billion of cash and cash equivalents generated from operating activities.

Preliminary Allocation of Consideration Transferred to Net Assets Acquired:

The following amounts represent the preliminary determination of the fair value of identifiable assets acquired and liabilities assumed from the Goodrich acquisition. The final determination of the fair value of certain assets and liabilities will be completed within the one year measurement period from the date of acquisition as required by the FASB ASC Topic 805, “Business Combinations”. The size and breadth of the Goodrich acquisition will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date including the significant contractual and operational factors underlying the customer relationship intangible asset; the final negotiated sales values for businesses that are required to be sold as part of the regulatory approval of the Goodrich acquisition; the assumptions underpinning certain reserves such as those for environmental obligations, and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented below:

(Dollars in millions)
Cash and cash equivalents		$	538
Accounts receivable, net			1,182
Inventories and contracts in progress, net			1,729
Future income tax benefits, current			280
Other assets, current			574
Fixed assets			2,342
Intangible assets:
	Customer relationships and related program assets		8,550
	Trademarks		1,550
Other assets			1,831
Short-term borrowings			(83)
Accounts payable			(443)
Accrued liabilities			(2,242)
Long-term debt			(2,961)
Future pension and postretirement benefit obligations			(1,745)
Other long-term liabilities:
	Customer contractual obligations		(2,050)
	Other long-term liabilities		(3,758)
Non-controlling interests			(41)
	Total identifiable net assets		5,253
Goodwill			11,167
	Total consideration transferred	$	16,420

In order to allocate the consideration transferred for Goodrich, the fair values of all identifiable assets and liabilities needed to be established. For accounting and financial reporting purposes, fair value is defined under FASB ASC Topic 820, “Fair Value Measurements and Disclosures” as the price that would be received upon sale of an asset or the amount paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. Use of different estimates and judgments could yield different results.

In determining the fair value of identifiable assets acquired and liabilities assumed, a review was conducted for any significant contingent assets or liabilities existing as of the acquisition date. The preliminary assessment did not note any significant contingencies related to existing legal or government action. Based upon our existing practices and phase II environmental assessments done on a number of Goodrich sites, we determined that environmental liability obligations of $232 million were assumed in connection with the acquisition.

The fair values of the customer relationship and related program intangible assets, which include the related aerospace program OEM and aftermarket cash flows, were determined by using an “income approach” which is the most common valuation approach utilized. Under this approach, the net earnings attributable to the asset or liability being measured are isolated using the discounted projected net cash flows. These projected cash flows are isolated from the projected cash flows of the combined asset group over the remaining economic life of the intangible asset or liability being measured. Both the amount and the duration of the cash flows are considered from a market participant perspective. Our estimates of market participant net cash flows considered historical and projected pricing, remaining developmental effort, operational performance including company specific synergies, aftermarket retention, product life cycles, material and labor pricing, and other relevant customer, contractual and market factors. Where appropriate, the net cash flows are probability-adjusted to reflect the uncertainties associated with the underlying assumptions, as well as the risk profile of the net cash flows utilized in the valuation. The probability-adjusted future cash flows are then discounted to present value using an appropriate discount rate. The customer relationship and related program intangible assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of the underlying programs of 10 to 25 years.

We also identified customer contractual obligations on certain original equipment manufacturing (OEM) development programs where the expected costs exceed the expected revenue under contract. We measured these liabilities under the measurement provisions of FASB ASC Topic 820, “Fair Value Measurements and Disclosures”, which is based on the price to transfer the obligation to a market participant at the measurement date, assuming that the liability will remain outstanding in the marketplace. Based on the estimated net cash outflows of the OEM developmental programs plus a reasonable contracting profit margin required to transfer the contracts to market participants, we recorded assumed liabilities of approximately $2 billion. These liabilities will be liquidated in accordance with the underlying economic pattern of obligations, as reflected by the net cash outflows incurred on the OEM contracts. Total consumption of the contractual obligation for the next five years is expected to be as follows: $283 million in 2013, $292 million in 2014, $221 million in 2015, $236 million in 2016, and $220 million in 2017.

Goodrich had not recorded an income tax liability on the unremitted earnings of its non-U.S. subsidiaries, which were approximately $853 million as of December 31, 2011. In connection with the Goodrich acquisition, UTC has made a determination to repatriate certain of these unremitted earnings, making such amounts subject to both U.S. and non-U.S. income taxes. Accordingly, an income tax liability of $219 million was recorded in purchase accounting for the unremitted earnings no longer considered permanently reinvested.

In accordance with conditions imposed for regulatory approval the Goodrich acquisition, UTC must dispose of the electric power systems and pumps and engine controls businesses of Goodrich. These businesses have been held separate from UTC's and Goodrich's ongoing businesses pursuant to regulatory obligations. On October 16, 2012, we announced an agreement to sell the electric power systems business for $400 million to Safran S.A., and on January 18, 2013, we announced an agreement to sell the pumps and engine controls business to Triumph Group, Inc. The closings of both sales are expected by the end of the first quarter of 2013 and are subject to regulatory approvals and other customary closing conditions.

Pre-Existing Relationships:

Our Pratt & Whitney division entered into a preferred supplier contract in 2010 with Goodrich for the development and subsequent production of nacelles for the PW1500G (Bombardier C Series) and PW1200G (Mitsubishi Regional Jet). That preferred supplier contract replaced previous contracts and preliminary Memorandum of Understandings entered into in 2006 and 2008. Under the 2010 agreement, Pratt & Whitney agreed to fund Goodrich's non-recurring development effort and established a recurring price for the production nacelles. Prior to the date of the Goodrich acquisition, Pratt & Whitney and Goodrich had asserted claims against each other in a contractual dispute and would have ultimately arbitrated the matter were it not for the acquisition. In accordance with FASB ASC Topic 805, “Business Combinations”, pre-existing relationships must be effectively settled at acquisition as the relationships become intercompany relationships upon acquisition and are eliminated in the post-combination financial statements. Any resulting settlement gains or losses should be measured at fair value and recorded on the acquisition date. Accordingly, a $46 million gain was recorded in other income by Pratt & Whitney in 2012 based upon a third party determination of the probability-weighted outcome had the matter gone to arbitration.

Acquisition-Related Costs:

Acquisition-related costs have been expensed as incurred. In 2012 and 2011, approximately $95 million and $84 million, respectively, of transaction costs (including integration costs) have been incurred in addition to approximately $67 million of restructuring costs, including exit costs in connection with the acquisition (see additional discussion in Note 13). In connection with the financing of the Goodrich acquisition, approximately $199 million in interest costs have been recorded in 2012.

Under Goodrich's pre-existing management continuity arrangements (MCAs), we assumed change-in-control obligations related to certain executives at Goodrich. We evaluated the change-in-control provisions governed by the MCAs and for certain of the executives, we determined that we had assumed liabilities of approximately $74 million as the benefit payments were effectively single trigger arrangements in substance. We measured the assumed liability based on fair value concepts of FASB ASC Topic 820, “Fair Value Measurements”, using weighted average techniques of possible outcomes of the employees electing to receive such benefits. We expensed approximately $12 million for MCAs where we amended the term of the MCAs beyond the original expiration date for certain executives.

Supplemental Pro-Forma Data:

Goodrich's results of operations have been included in UTC's financial statements for the period subsequent to the completion of the acquisition on July 26, 2012. Goodrich contributed sales of approximately $3.6 billion and operating profit of approximately $245 million for the period from the completion of the acquisition through December 31, 2012. The following unaudited supplemental pro-forma data presents consolidated information as if the acquisition had been completed on January 1, 2011. The pro-forma results were calculated by combining the results of UTC with the stand-alone results of Goodrich for the pre-acquisition periods, which were adjusted to account for certain costs which would have been incurred during this pre-acquisition period:


(Dollars in millions, except per share amounts)			2012		2011
Net sales		$	62,173	$	63,233
Net income attributable to common shareowners
	from continuing operations		5,095		4,969
Basic earnings per share of common stock
	from continuing operations		5.69		5.57
Diluted earnings per share of common stock
	from continuing operations		5.62		5.48

The unaudited supplemental pro-forma data above includes the following significant adjustments made to account for certain costs which would have been incurred if the acquisition had been completed on January 1, 2011, as adjusted for the applicable tax impact. As the Goodrich acquisition was completed on July 26, 2012, the pro-forma adjustments for 2012 and 2011 in the table below only include the required adjustments through July 26, 2012:


(Dollars in millions)			2012		2011
Amortization of inventory fair value adjustment ¹		$	(103)	$	103
Amortization of acquired Goodrich intangible assets, net ²			108		184
Utilization of contractual customer obligation ³			(96)		(200)
UTC/Goodrich fees for advisory, legal, accounting services ⁴			-		196
Interest expense incurred on acquisition financing, net ⁵			63		175

	¹ Added the expense for inventory fair value adjustments which would have been amortized as the corresponding inventory would have been completely sold during the first two quarters of 2011, and removed the corresponding expense recognized during the last two quarters of 2012.

	² Added the additional amortization of the acquired Goodrich intangible assets recognized at fair value in purchase accounting and eliminated the historical Goodrich intangible asset amortization expense.

	³Added the additional utilization of the Goodrich contractual customer obligation recognized in purchase accounting.

	⁴ Added the UTC/Goodrich fees that were incurred in connection with the acquisition of Goodrich to the first quarter of 2011.

	⁵ Added the additional interest expense for the debt incurred to finance our acquisition of Goodrich and reduced interest expense for the debt fair value adjustment which would have been amortized.

The unaudited supplemental pro-forma financial information does not reflect the potential realization of cost savings relating to the integration of the two companies. Further, the pro-forma data should not be considered indicative of the results that would have occurred if the acquisition and related financing been consummated on January 1, 2011, nor are they indicative of future results.

Other Acquisition and Disposition Activity:

In 2012, UTC approved plans for the divestiture of a number of non-core businesses. Cash generated from these divestitures is intended to be used to repay debt incurred to finance the Goodrich acquisition. See Note 3 for further discussion.

On June 29, 2012, Pratt & Whitney, Rolls-Royce plc (Rolls-Royce), MTU Aero Engines AG (MTU), and Japanese Aero Engines Corporation (JAEC), participants in the IAE collaboration, completed a restructuring of their interests in IAE. Under the terms of the agreement, Rolls-Royce sold its ownership and collaboration interests in IAE to Pratt & Whitney, while also entering into an agreement to license its V2500 intellectual property to Pratt & Whitney. In exchange for the increased ownership and collaboration interests and intellectual property license, Pratt & Whitney paid Rolls-Royce $1.5 billion at closing with additional payments due to Rolls-Royce during the fifteen year period following closing of the purchase, conditional upon each hour flown by V2500-powered aircraft in service at the closing. The collaboration interest and intellectual property licenses are reflected as intangible assets and will be amortized in relation to the economic benefits received over the remaining estimated 30 year life of the V2500 program. Rolls-Royce will continue to support the program as a strategic supplier for the V2500 engine and continue to manufacture parts and assemble engines. Pratt & Whitney entered into a collaboration arrangement with MTU with respect to a portion of the acquired collaboration interest in IAE for consideration of approximately $233 million with additional payments due to Pratt & Whitney in the future. As a result of these transactions, Pratt & Whitney holds a 61% net interest in the collaboration and a 49.5% ownership interest in IAE. IAE's business purpose is to coordinate the design, development, manufacturing and product support of the V2500 program through involvement with the collaborators. IAE retains limited equity with the primary economics of the V2500 program passed to the participants in the separate collaboration arrangement. As such, IAE was determined to be a variable interest entity (VIE), and Pratt & Whitney its primary beneficiary under the criteria established in the FASB ASC Topic “Consolidations” and has, therefore, been consolidated post-transaction. The consolidation of IAE resulted in a gain of $21 million recognized during the second quarter of 2012 on the re-measurement to fair value of our previously held equity interest. The carrying amounts and classification of assets and liabilities for IAE in our Consolidated Balance Sheet as of December 31, 2012 are as follows:


(Dollars in millions)
Current assets		$	1,308
Noncurrent assets			899
	Total assets	$	2,207

Current liabilities		$	1,468
Noncurrent liabilities			781
	Total liabilities	$	2,249

UTC Climate, Controls & Security continued its portfolio transformation efforts in 2012 with the completed and pending disposition of a number of businesses resulting in impairment and other charges totaling approximately $180 million. UTC Climate, Controls & Security also sold a controlling interest in a manufacturing and distribution joint venture in Asia generating a gain of approximately $215 million, and a controlling interest in a Canadian distribution business generating a gain of approximately $120 million.

In November 2011, UTC Climate, Controls & Security formed a venture controlled by Midea Group of China (Midea) for the manufacture and distribution of heating, ventilating, and air-conditioning (HVAC) products in Brazil, Argentina, and Chile. The venture is comprised of UTC Climate, Controls & Security's existing HVAC operations in the three countries and Midea's distribution entity. Midea owns 51% of the venture and UTC Climate, Controls & Security 49%. This joint venture strengthened UTC Climate, Controls & Security's global strategic relationship with Midea and expands the manufacturing and distribution of residential and light commercial HVAC systems in Brazil, Argentina, and Chile. UTC Climate, Controls & Security recognized a gain of approximately $80 million in 2011 as a result of this transaction.

During 2011, we recorded an other-than-temporary impairment charge totaling $66 million on an equity investment held by UTC Climate, Controls & Security, in order to write-down our investment to market value as of December 31, 2011. This impairment is recorded within “Other income, net” on our Consolidated Statement of Operations.

On March 1, 2010, we completed the acquisition of the GE Security business for approximately $1.8 billion, including debt assumed of $32 million. The GE Security business supplies security and fire safety technologies for commercial and residential applications through a broad product portfolio that includes fire detection and life safety systems, intrusion alarms, and video surveillance and access control systems. This business, which has been integrated into our UTC Climate, Controls & Security segment, enhanced UTC Climate, Controls & Security's geographic diversity through GE Security's strong North American presence, while increasing total product and technology offerings. In connection with the acquisition of GE Security, we recorded approximately $600 million of identifiable intangible assets and $1.1 billion of goodwill. The goodwill recorded reflects synergies expected to be realized through the combination of GE Security's products, resources and management talent with those of the existing UTC Climate, Controls & Security business to enhance competitiveness, accelerate the development of certain product offerings, drive improved operational performance and secure additional service channels. Additionally, the combined business has provided the opportunity for significant improvements to the cost structure through the rationalization of general and administrative expenditures as well as research and development efforts.

During 2010, we recorded approximately $86 million of asset impairment charges, for assets that have met the “held-for-sale” criteria, related to disposition activity within both UTC Climate, Controls & Security and UTC Aerospace Systems. These asset impairment charges are recorded within Cost of products sold on our Consolidated Statement of Operations. The asset impairment charges consist of an approximately $58 million charge associated with UTC Climate, Controls & Security's ongoing portfolio transformation and an approximately $28 million charge at UTC Aerospace Systems related to the disposition of an aerospace business as part of UTC Aerospace System's efforts to implement low cost sourcing initiatives.

During 2010, we completed the acquisition of Clipper. In 2010, we recorded net charges related to declines in fair value related to our investment in Clipper of approximately $138 million. These amounts remain in 2010 Other income, net in results of continuing operations, as Clipper was accounted for as an equity-method investment through December 2010. Clipper has been reclassified to discontinued operations for 2012 and 2011, as it was a wholly-owned entity of UTC, and was sold in the third quarter of 2012. See additional discussion at Note 3.

Goodwill. The changes in the carrying amount of goodwill, by segment, are as follows:

(Dollars in millions)		Balance as of January 1, 2012		Goodwill resulting from business combinations		Foreign currency translation and other		Balance as of December 31, 2012
Otis		$	1,516	$	24	$	43	$	1,583
UTC Climate, Controls & Security			9,758		89		21		9,868
Pratt & Whitney			1,223		280		(265)		1,238
UTC Aerospace Systems			4,475		11,283		(1,004)		14,754
Sikorsky			348		-		5		353

Total Segments			17,320		11,676		(1,200)		27,796
Eliminations and other			623		4		(622)		5

	Total	$	17,943	$	11,680	$	(1,822)	$	27,801

UTC Aerospace Systems goodwill increased $11.3 billion principally as a result of the Goodrich acquisition. The goodwill results from the workforce acquired with the business as well as the significant synergies that are expected to be realized through the consolidation of manufacturing facilities and overhead functions. No amount of this goodwill is deductible for tax purposes. The goodwill acquired has been allocated to the two reporting units within the UTC Aerospace Systems segment.

Pratt & Whitney goodwill increased $280 million due to the increase in ownership interest and consolidation of IAE. The goodwill is deductible for tax purposes.

The approximately $1.8 billion decrease reflected under “Foreign currency translation and other” in the table above primarily reflects the decision to divest a number of non-core businesses and the resulting reclassification to assets held for sale. See Note 3 for further discussion. In addition, approximately $360 million of goodwill was transferred from UTC Aerospace Systems to Pratt & Whitney in connection with the transfer of the auxiliary power unit (APU) business from UTC Aerospace Systems to Pratt & Whitney. See Note 19 for further discussion of the transfer of the APU business.

We early-adopted FASB ASU No. 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment” in connection with the performance of our annual goodwill and indefinite-lived intangible assets impairment tests. This ASU intends to align impairment testing guidance among long-lived asset categories. This ASU allows for an assessment based on qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired prior to determining whether it is necessary to perform the quantitative impairment test in accordance with FASB ASC Subtopic 350-30, “Intangibles—Goodwill and Other—General Intangibles Other than Goodwill.” We completed our annual impairment testing in the third quarter of 2012 and determined that no significant adjustments to the carrying amount of goodwill or indefinite lived intangible assets were necessary beyond those charges recorded in connection with certain non-core businesses to be disposed as discussed further in Note 3.

The increase to amortized and unamortized intangible assets pertains to the Goodrich and IAE transactions. Acquired intangible assets are recognized at fair value in purchase accounting and then amortized to cost of sales and selling, general & administrative expenses over the applicable useful lives. The customer relationship intangible assets are being amortized on a straight line basis as it approximates the underlying economic pattern of benefit. The IAE collaboration intangible was not amortized in 2012 as the underlying cash flows were negative for the year. Amortization of intangible assets in 2012 and 2011 was $547 million and $398 million, respectively.

The following is the expected amortization of intangible assets for 2013 through 2017:

Notes to Consolidated Financial Statements [Abstract]

Note 3: Discontinued Operations

In 2012, the UTC Board of Directors approved plans for the divestiture of a number of non-core businesses. Cash generated from these divestitures is intended to be used to repay debt incurred to finance the Goodrich acquisition. These divestitures, when completed, are expected to generate approximately $3 billion in net cash, on an after-tax basis.

In the first quarter of 2012, the legacy Hamilton Sundstrand Industrial businesses, Rocketdyne and Clipper all met the “held-for-sale” criteria. On June 29, 2012, management approved a plan for the divestiture of UTC Power. The operating results of Clipper and UTC Power had previously been reported within “Eliminations & other” in our segment disclosure. The results of operations, including the net gains/losses realized or expected on disposition, and the related cash flows which result from these non-core businesses have been reclassified to discontinued operations in our Consolidated Statement of Operations and Consolidated Statement of Cash Flows for all periods presented. The remaining assets and liabilities of these non-core businesses to be sold in the first half of 2013, have been reclassified to Assets held for sale and Liabilities held for sale in our Consolidated Balance Sheet as of December 31, 2012. The sale of the legacy Hamilton Sundstrand Industrials business was completed in December 2012, while the divestiture of Clipper was completed in the third quarter of 2012. Cash flows from the operation of Rocketdyne and UTC Power will continue to be reported in discontinued operations until their disposals are completed.

As a result of the decision to dispose of these businesses, UTC has recorded pre-tax goodwill impairment charges of approximately $360 million and $590 million related to Rocketdyne and Clipper, respectively, and other pre-tax net asset impairment charges of approximately $179 million related to UTC Power in discontinued operations during 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. The impairment charge at UTC Power results from adjusting the net assets of the business to the estimated fair value expected to be realized upon sale, less costs to sell the business, and further reflects the loss in value from the disposition of the business before the benefits of the technology investments were fully realized. There could be gains or additional losses recorded upon final disposition of these businesses based upon the values, terms and conditions that are ultimately negotiated.

On December 13, 2012, we completed the sale of the legacy Hamilton Sundstrand Industrial businesses to BC Partners and The Carlyle Group for $3.4 billion. The sale generated a pre-tax gain of approximately $2.1 billion ($0.9 billion after tax) which has been included in discontinued operations in the accompanying Consolidated Statement of Operations. The high effective tax rate is primarily attributable to non-deductible goodwill.

On December 22, 2012, we announced an agreement to sell UTC Power to ClearEdge Power. The transaction is expected to close in the first quarter of 2013 and is largely subject only to the completion of certain administrative matters. On December 12, 2012, we announced an agreement to sell Pratt & Whitney Power Systems to Mitsubishi Heavy Industries. The transaction is expected to close in the first half of 2013. The sale is subject to customary closing conditions, including receipt of regulatory approvals. The financial results of Pratt & Whitney Power Systems have not been reclassified to discontinued operations as Pratt & Whitney is expected to have a continuing involvement with the business post disposition.

On August 7, 2012, we completed the disposition of Clipper to a private equity acquirer. The disposition resulted in payments totaling approximately $367 million, which included capitalization of the business prior to sale, transaction fees, and funding of operations as the acquirer took control of a business with significant net liabilities. These payments are largely reflected in Net cash flows provided by (used in) investing activities within the discontinued operations section of the Consolidated Statement of Cash Flows. We have no continuing involvement with the Clipper business following disposition.

On July 23, 2012, we announced an agreement to sell Rocketdyne to GenCorp Inc. for $550 million. The transaction is expected to close in the first half of 2013. The sale is subject to customary closing conditions, including receipt of regulatory approvals.

The following summarized financial information related to these non-core businesses has been segregated from continuing operations, as applicable, and is included in Net income from discontinued operations in the accompanying Consolidated Statement of Operations:

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 have been anti-dilutive. For 2012, there were 4.7 million anti-dilutive stock awards excluded from the computation. For 2011, there were no anti-dilutive stock awards excluded from the computation. For 2010, the number of stock awards excluded from the computation was 11.4 million. There was no impact on diluted earnings per share due to our equity unit offering in 2012.

Note 5: Commercial Aerospace Industry Assets and Commitments

We have receivables and other financing assets with commercial aerospace industry customers totaling $5,731 million and $3,736 million at December 31, 2012 and 2011, respectively. Customer financing assets related to commercial aerospace industry customers consist of products under lease of $644 million and notes and leases receivable of $584 million.

Financing commitments, in the form of secured debt, guarantees or lease financing, are provided to commercial aerospace customers. The extent to which the financing commitments will be utilized is not currently known, since customers may be able to obtain more favorable terms from other financing sources. We may also arrange for third-party investors to assume a portion of these commitments. If financing commitments are exercised, debt financing is generally secured by assets with fair market values equal to or exceeding the financed amounts with interest rates established at the time of funding. We may also lease aircraft and subsequently sublease the aircraft to customers under long-term non-cancelable operating leases. In some instances, customers may have minimum lease terms that result in sublease periods shorter than our lease obligation. Lastly, we have made residual value and other guarantees related to various commercial aerospace customer financing arrangements. The estimated fair market values of the guaranteed assets equal or exceed the value of the related guarantees, net of existing reserves.

We also have other contractual commitments, including commitments to secure certain contractual rights to provide product on new aircraft platforms. Payments made on these contractual commitments are included within other intangible assets and are to be amortized as the related OEM and aftermarket units are delivered over the estimated program life. Our commercial aerospace financing and other contractual commitments as of December 31, 2012 were approximately $10.9 billion, which include approximately $5.8 billion of IAE commitments. We have entered into certain collaboration arrangements, which may include participation by our collaboration partners in these commitments.

The following is the expected maturity of commercial aerospace industry assets and commitments as of December 31, 2012:

(Dollars in millions)	Committed		2013		2014		2015		2016			2017	Thereafter
Notes and leases receivable	$	584	$	99	$	99	$	68	$	44	$	59	$	215
Commercial aerospace financing commitments	$	3,237	$	339	$	785	$	365	$	464	$	334	$	950
Other commercial aerospace commitments		7,628		736		567		629		676		638		4,382
Collaboration partners' share		(2,027)		(252)		(287)		(228)		(193)		(165)		(902)

Total commercial commitments	$	8,838	$	823	$	1,065	$	766	$	947	$	807	$	4,430

Other commercial aerospace commitments include amounts related to our agreement with Embraer, which we announced on January 8, 2013, to power the next generation Embraer E-Jet family.

In exchange for the increased ownership and collaboration interests and intellectual property license, Pratt & Whitney paid Rolls-Royce $1.5 billion at closing with additional payments due to Rolls-Royce contingent upon each hour flown by the V2500-powered aircraft in service as of June 29, 2012 during the fifteen year period following closing of the purchase. These payments will be capitalized as a collaboration intangible asset and amortized in relation to the economic benefits received over the projected remaining 30 year life of the V2500 program. The flight hour payments are included in other commercial aerospace commitments in the table above.

Our financing obligations with customers are contingent upon maintenance of certain levels of financial condition by the customers. In addition, we have residual value and other guarantees of $346 million as of December 31, 2012.

We have long-term aftermarket maintenance contracts with commercial aerospace industry customers for which revenue is recognized in proportion to actual costs incurred relative to total expected costs to be incurred over the respective contract periods. Billings, however, are typically based on factors such as engine flight hours. The timing differences between the billings and the maintenance costs incurred generates both deferred assets and deferred revenues. Deferred assets under these long-term aftermarket contracts totaled $391 million and $235 million at December 31, 2012 and 2011, respectively, and are included in Other assets in the accompanying Consolidated Balance Sheet. Deferred revenues generated totaled $2,760 million and $1,708 million at December 31, 2012 and 2011, respectively, and are included in Accrued liabilities and Other long-term liabilities in the accompanying Consolidated Balance Sheet.

The increases reflected above as of December 31, 2012, as compared to December 31, 2011, primarily reflect the impacts of the Goodrich acquisition and our consolidation of IAE. See Note 2 for further discussion related to acquisitions.

Reserves related to aerospace receivables and financing assets were $210 million and $169 million at December 31, 2012 and 2011, respectively. Reserves related to financing commitments and guarantees were $67 million and $73 million at December 31, 2012 and 2011, respectively.

Raw materials, work-in-process and finished goods are net of valuation reserves of $866 million and $884 million as of December 31, 2012 and 2011, respectively. As of December 31, 2012 and 2011, inventory also includes capitalized contract development costs of $823 million and $776 million, respectively, related to certain aerospace programs. These capitalized costs will be liquidated as production units are delivered to the customer. The capitalized contract development costs within inventory principally relate to capitalized costs on Sikorsky's CH-148 contract with the Canadian Government. The CH-148 is a derivative of the H-92, a military variant of the S-92 helicopter.

Contracts in progress principally relate to elevator and escalator contracts and include costs of manufactured components, accumulated installation costs and estimated earnings on incomplete contracts.

Our sales contracts in many cases are long-term contracts expected to be performed over periods exceeding twelve months. At both December 31, 2012 and 2011, approximately 66% of total inventories and contracts in progress have been acquired or manufactured under such long-term contracts, a portion of which is not scheduled for delivery within the next twelve months.

Other borrowings		183		175
Total short-term borrowings	$	503	$	630

At December 31, 2012, we had revolving credit agreements with various banks permitting aggregate borrowings of up to $4 billion pursuant to a $2 billion revolving credit agreement and a $2 billion multicurrency revolving credit agreement, both of which expire in November 2016. As of December 31, 2012, there were no borrowings under either of these revolving credit agreements. The undrawn portions of these revolving credit agreements are also available to serve as backup facilities for the issuance of commercial paper. As of December 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.

The weighted-average interest rates applicable to short-term borrowings outstanding at December 31, 2012 and 2011 were 0.9% and 1.5%, respectively. At December 31, 2012, approximately $1.7 billion was available under short-term lines of credit with local banks at our various domestic and international subsidiaries.

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 due December 31, 2012. On July 26, 2012 we borrowed the full $2 billion available under this facility to partially finance the cash consideration of the Goodrich acquisition and pay related fees, expenses and other amounts due and payable by UTC as a result of the acquisition. The outstanding principal balance under this term loan credit agreement was prepaid in two equal payments on November 5 and December 5, 2012.

On June 1, 2012, we issued a total of $9.8 billion of long-term debt, which is comprised of $1.0 billion aggregate principal amount of 1.200% notes due 2015, $1.5 billion aggregate principal amount of 1.800% notes due 2017, $2.3 billion aggregate principal amount of 3.100% notes due 2022, $3.5 billion aggregate principal amount of 4.500% notes due 2042, $1.0 billion aggregate principal amount of three-month LIBOR plus 0.270% floating rate notes due 2013, and $0.5 billion aggregate principal amount of three-month LIBOR plus 0.500% floating rate notes due 2015. We utilized the net proceeds of these notes of approximately $9.6 billion to partially finance the cash consideration of the Goodrich acquisition and pay related fees, expenses and other amounts due and payable by UTC as a result of the acquisition. The three-month LIBOR rate as of December 31, 2012 was approximately 0.3%.

On June 18, 2012, we issued 22,000,000 equity units and received approximately $1.1 billion in net proceeds. Each equity unit has a stated amount of $50 and initially is in the form of a corporate unit consisting of (a) a freestanding stock purchase contract under which the holder will purchase from us on August 1, 2015, a number of shares of our common stock determined pursuant to the terms of the agreement and (b) a 1/20, or 5.0%, undivided beneficial ownership interest in $1,000 principal amount on our 1.55% junior subordinated notes due 2022. Holders of the equity units are entitled to receive quarterly contract adjustment payments at a rate of 5.95% per year of the stated amount of $50 per equity unit, subject to our right to defer such payments. We used the net proceeds of the equity units to partially finance the cash consideration of the Goodrich acquisition and pay related fees, expenses and other amounts due and payable by UTC as a result of the acquisition.

The net proceeds from the sale of the equity units were allocated between the purchase contracts and the notes in our financial statements based on the underlying fair value of each instrument at the time of issuance taking into consideration the contract adjustment payments. The fair value of the purchase contracts is expected to approximate the present value of the contract adjustment payments and was recorded as a reduction to Common Stock, with an offsetting credit to liabilities. This liability will be accreted over three years through interest charges to the statement of operations based on a constant rate calculation. The purchase contracts are reflected in our diluted earnings per share calculations using the treasury stock method.

To finance the remainder of the cash consideration of the Goodrich acquisition and pay related fees, expenses and other amounts due and payable, we utilized $3.2 billion from the issuance of commercial paper and approximately $0.5 billion of cash and cash equivalents generated from operating activities. In addition, as a result of the Goodrich acquisition, we assumed $3.0 billion of debt, including an adjustment of $600 million to increase the value of long-term debt assumed to its fair market value. Details of the debt assumed are included in the long-term debt table below.

On July 26, 2012, upon completing the Goodrich acquisition, we terminated the bridge credit agreement, initially entered into as of November 8, 2011, with various financial institutions that had provided for a $15 billion unsecured bridge loan facility which was available to partially fund the cash consideration of the Goodrich acquisition and pay related fees, expenses and other amounts due and payable by UTC as a result of the acquisition. See Note 2 for further details regarding the completion of the Goodrich acquisition.

On December 6, 2012, we announced that we had commenced cash tender offers for six series of outstanding notes issued by Goodrich. These offers expired on January 7, 2013. Holders validly tendering their notes by December 19, 2012 received consideration determined by reference to a fixed spread over the yield to maturity (or, in the case of one series, yield to call) of the applicable U.S. Treasury security with the same maturity, plus an early tender payment of $30 per $1,000 principal amount of notes accepted for purchase. Holders validly tendering their notes after December 19, 2012 but prior to January 8, 2013 received consideration determined by reference to a fixed spread over the yield to maturity (or, in the case of one series, yield to call) of the applicable U.S. Treasury security with the same maturity. A total of $635 million principal amount of all notes subject to the tender offer and $126 million of the fair value adjustment were repaid, including approximately $30.6 million principal amount of the 2018 notes, approximately $129 million principal amount of the 2020 notes, approximately $305.2 million principal amount of the 2021 notes, approximately $9.1 million principal amount of the 2027 notes, approximately $120.2 million principal amount of the 2036 notes, and approximately $40.8 million principal amount of the 2038 notes. The effective interest rate on these notes was between 3.6% and 7.1%. The extinguishment loss was approximately $26 million and was recognized within Interest expense, net.

Long-term debt consisted of the following:

The project financing obligations noted above are associated with the sale of rights to unbilled revenues related to the ongoing activity of an entity owned by UTC Climate, Controls and Security. The percentage of total short-term borrowings and long-term debt at variable interest rates was 9% and 7% at December 31, 2012 and 2011, respectively. Interest rates on our commercial paper borrowings are considered variable due to their short-term duration and high-frequency of turnover.

Notes to Consolidated Financial Statements [Abstract]

Note 11: Income Taxes

The income tax expense (benefit) for the years ended December 31, consisted of the following components:

(Dollars in millions)			2012		2011		2010
Current:
	United States:

Income tax expense			$	1,711	$	2,134	$	1,725

Attributable to items credited to equity and goodwill			$	297	$	864	$	276

Future income taxes represent the tax effects of transactions, which are reported in different periods for tax and financial reporting purposes. These amounts consist of the tax effects of temporary differences between the tax and financial reporting balance sheets and tax carryforwards. Current and non-current future income tax benefits and payables within the same tax jurisdiction are generally offset for presentation in the Consolidated Balance Sheet.

During 2012, UTC completed the Goodrich acquisition. The accounting for the current and non-current future income tax benefits and payables was materially impacted by the acquisition, resulting in a shift of the classification of the tax effects of certain temporary differences from non-current income tax benefits to non-current future income taxes payable.

The tax effects of net temporary differences and tax carryforwards which gave rise to future income tax benefits and payables at December 31, 2012 and 2011 are as follows:

(Dollars in millions)		2012		2011
Future income tax benefits:
	Insurance and employee benefits	$	1,168	$	2,579
	Other asset basis differences		119		(569)
	Other liability basis differences		1,052		1,046
	Tax loss carryforwards		382		723
	Tax credit carryforwards		1,107		1,247
	Valuation allowances		(618)		(977)

		$	3,210	$	4,049

Future income taxes payable:
	Insurance and employee benefits	$	(2,238)	$	163
	Other asset basis differences		4,440		681
	Other items, net		(195)		71
	Tax loss carryforwards		(409)		-
	Tax credit carryforwards		(80)		-
	Valuation allowances		286		-

		$	1,804	$	915

The future income taxes payable balances of $1,804 million and $915 million, reflected in the table above, for the years ended December 31, 2012 and 2011, respectively, are reported in accrued liabilities and other long-term liabilities on the balance sheet.

Valuation allowances have been established primarily for tax credit carryforwards, tax loss carryforwards, and certain foreign temporary differences to reduce the future income tax benefits to expected realizable amounts.

During 2012, approximately $225 million of valuation allowances were released as a result of internal legal entity reorganizations. These internal reorganizations were a component of our ongoing efforts to improve business efficiency. These valuation allowance releases are included in the effective tax rate reconciliation table within the tax on international activities component.

The sources of income before income taxes are:

(Dollars in millions)	2012		2011		2010
United States	$	2,595	$	3,168	$	2,441
Foreign		4,316		4,182		3,807

	$	6,911	$	7,350	$	6,248

With few exceptions, U.S. income taxes have not been provided on undistributed earnings of UTC's international subsidiaries. These earnings relate to ongoing operations and were approximately $22 billion as of December 31, 2012. It is not practicable to estimate the amount of tax that might be payable. Our intention is to reinvest these earnings permanently outside the U.S. or to repatriate the earnings only when it is tax effective to do so.

Differences between effective income tax rates and the statutory U.S. federal income tax rate are as follows:

	2012	2011	2010
Statutory U.S. federal income tax rate	35.0%	35.0%	35.0%
Tax on international activities	(6.4)%	(4.4)%	(7.8)%
Tax audit settlements	(3.4)%	(0.9)%	-
Other	(0.4)%	(0.7)%	0.4%

Effective income tax rate	24.8%	29.0%	27.6%

The 2012 effective tax rate decreased as compared to 2011. The 2012 effective tax rate reflects a favorable non-cash income tax adjustment of approximately $203 million related to the conclusion of the IRS's examination of UTC's 2006 – 2008 tax years, as well as a reduction in tax expense of $34 million related to the favorable resolution of disputed tax matters with the Appeals Division of the IRS for the tax years 2004 - 2005. Also included in the 2012 effective tax rate is the favorable income tax impact of $225 million related to the release of non-U.S. valuation allowances resulting from internal legal entity reorganizations. This is reported in the table above in tax on international activities.

The 2011 effective tax rate reflects approximately $63 million of favorable income tax adjustments related to the settlement of two refund claims for years prior to 2004, as well as a favorable tax impact of $17 million related to a U.K. tax rate reduction enacted in 2011. These favorable tax adjustments are partially offset by non-deductible charges accrued in 2011.

The 2010 effective income tax rate reflects a non-recurring tax expense reduction associated with management's decision to repatriate additional high tax dividends from 2010 earnings to the U.S. as a result of U.S. tax legislation enacted in 2010. This was partially offset by the non-deductibility of impairment charges, the adverse impact from the health care legislation related to the Medicare Part D program and other increases to UTC's effective income tax rate.

At December 31, 2012, tax credit carryforwards, principally state and foreign, and tax loss carryforwards, principally state and foreign, were as follows:

(Dollars in millions)	Tax Credit Carryforwards		Tax Loss Carryforwards
Expiration period:
2013-2017	$	52	$	626
2018-2022		17		378
2023-2032		310		1,053
Indefinite		808		2,115
Total	$	1,187	$	4,172

At December 31, 2012, we had gross tax-effected unrecognized tax benefits of $1,073 million, all of which, if recognized, would impact the effective tax rate. The table below includes both additional unrecognized tax benefits and related interest attributable to the acquisition of Goodrich in 2012. A reconciliation of the beginning and ending amounts of unrecognized tax benefits and interest expense related to unrecognized tax benefits for the years ended December 31, 2012, 2011, and 2010 is as follows:

(Dollars in millions)		2012		2011		2010
Balance at January 1	$	946	$	891	$	793
Additions for tax positions related to the current year		232		71		115
Additions for tax positions of prior years		221		71		80
Reductions for tax positions of prior years		(21)		(24)		(81)
Settlements		(305)		(63)		(16)

Balance at December 31	$	1,073	$	946	$	891


Gross interest expense related to unrecognized tax benefits	$	40	$	23	$	27

Total accrued interest balance at December 31	$	270	$	165	$	144

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.

During the first quarter of 2012, the IRS completed examination fieldwork for our 2006 through 2008 tax years and issued its audit report. Based on the IRS audit report, we filed a protest with respect to certain IRS-proposed adjustments with which we do not agree. Resolution discussions with the Appeals Division of the IRS will commence on the unagreed items in 2013. However, the timing of any resolution is currently uncertain. During the third quarter of 2012, we reached final resolution with the Appeals Division of the IRS for our 2004 and 2005 tax years regarding certain proposed adjustments with which we did not agree. As a result of the above described events with respect to our 2004 – 2005 and 2006 – 2008 tax years, we recorded reductions in tax expense in the first and third quarters of 2012 in the aggregate amount of $237 million. IRS audit fieldwork for tax years 2009 and 2010 commenced in the first quarter of 2012 and is currently expected to continue into 2014.

UTC completed the Goodrich acquisition during 2012. Goodrich pre-acquisition tax years are also the subject of certain IRS audit, appeals and litigation activity. Goodrich tax years 2001 and 2002 are currently the subject of litigation involving the proper timing of certain deductions, which litigation is expected to continue through 2013. Goodrich tax years 2005 and 2006 are the subject of litigation with respect to a separate issue involving the proper timing of deductions, which litigation is also expected to continue through 2013. Goodrich tax years 2007 and 2008 are currently before the Appeals Division of the IRS for resolution discussions regarding certain proposed adjustments with which UTC does not agree, which are expected to continue through 2013. Goodrich tax years 2009 and 2010 are currently under review by the Examination Division of the IRS, which is expected to continue through mid-2013. We expect the IRS to commence examination activity for Goodrich tax years 2011 and 2012 during the second half of 2013.

During 2011, we reached final resolution with the IRS on two refund claims that had been pending with respect to pre-2004 tax years and refunds were received in accordance with the resolutions. A reduction in tax expense in the amount of $63 million and pretax interest income in the amount of $89 million was recognized during 2011 associated with the resolution of these claims.

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 $40 million to a net decrease of $275 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. Not included in the range is €176 million (approximately $234 million) related to certain deductions claimed in France for tax years 2008 through 2010 that the French Revenue Authority has proposed to disallow. Resolution discussions with the French Revenue Authority have been unsuccessful to date and UTC may be required to pursue the defense of this matter through litigation, which could be commenced within the next twelve months. UTC intends to assert a vigorous defense and believes it should prevail on the issue. Accordingly, no tax expense has been accrued for this matter.

Also not included in the above range is €203 million (approximately $270 million) of tax benefits that we have claimed related to a 1998 German reorganization. Upon audit, these tax benefits were disallowed by the German Tax Office. In 2012, we filed suit in the local German Tax Court. In 2008 the German Federal Tax Court (FTC) denied benefits to another taxpayer in a case involving a German tax law relevant to our reorganization. The determination of the FTC 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 FTC for further consideration of certain related issues. In May 2010, the FTC released its decision, in which it resolved certain tax issues that may be relevant to our suit and remanded the case to a lower court for further development. In 2012, the lower court decided in favor of the taxpayer and the government appealed the findings to the FTC. After consideration of the ECJ decision, the latest FTC decision and the lower 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.

- Definition

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 12: Employee Benefit Plans

12 Months Ended

Dec. 31, 2012

Notes to Consolidated Financial Statements [Abstract]

Note 12: Employee Benefit Plans

We sponsor numerous domestic and foreign employee benefit plans, which are discussed below.

Employee Savings Plans. We sponsor various employee savings plans. Our contributions to employer sponsored defined contribution plans were $256 million, $218 million and $200 million for 2012, 2011 and 2010, respectively. Included in the current year contributions to employer sponsored defined contribution plans is $26 million of contributions to Goodrich defined contribution plans. Effective January 1, 2010, newly hired non-union domestic employees receive all of their retirement benefits through the defined contribution savings plan.

Our non-union domestic employee savings plan uses an Employee Stock Ownership Plan (ESOP) for employer contributions. External borrowings were used by the ESOP to fund a portion of its purchase of ESOP stock from us. The external borrowings have been extinguished and only re-amortized loans remain between UTC and the ESOP Trust. As ESOP debt service payments are made, common stock is released from an unreleased shares account. ESOP debt may be prepaid or re-amortized to either increase or decrease the number of shares released so that the value of released shares equals the value of plan benefit. We may also, at our option, contribute additional common stock or cash to the ESOP.

Shares of common stock are allocated to employees' ESOP accounts at fair value on the date earned. Cash dividends on common stock held by the ESOP are used for debt service payments. Participants receive additional shares in lieu of cash dividends. Common stock allocated to ESOP participants is included in the average number of common shares outstanding for both basic and diluted earnings per share. At December 31, 2012, 32.8 million common shares had been allocated to employees, leaving 17.1 million unallocated common shares in the ESOP Trust, with an approximate fair value of $1.4 billion.

Pension Plans. We sponsor both funded and unfunded domestic and foreign defined benefit pension plans that cover the majority of our employees. Our plans use a December 31 measurement date consistent with our fiscal year.

As part of the Goodrich acquisition on July 26, 2012, we assumed approximately $5.2 billion of pension projected benefit obligations and $3.8 billion of plan assets.

Qualified domestic pension plan benefits comprise approximately 75% of the projected benefit obligation. Benefits for union employees are generally based on a stated amount for each year of service. For non-union employees, benefits are generally based on an employee's years of service and compensation near retirement. Effective January 1, 2015, this formula will change to the existing cash balance formula that was adopted in 2003 for newly hired non-union employees and for other non-union employees who made a one-time voluntary election to have future benefit accruals determined under this formula. This plan change resulted in a $623 million reduction in the projected benefit obligation as of December 31, 2009 and an additional $204 million reduction in the projected benefit obligation as of July 26, 2012 when applied to legacy Goodrich salaried employees. Certain foreign plans, which comprise approximately 23% of the projected benefit obligation, are considered defined benefit plans for accounting purposes. Nonqualified domestic pension plans provide supplementary retirement benefits to certain employees and are not a material component of the projected benefit obligation.

We made $201 million of cash contributions to our domestic defined benefit pension plans and made $229 million of cash contributions to our foreign defined benefit pension plans in 2012. In 2011, we made $156 million of cash contributions and contributed $450 million in UTC common stock to our domestic defined benefit pension plans and made $395 million of cash contributions to our foreign defined benefit pension plans.

Major assumptions used in determining the benefit obligation and net cost for pension plans are presented in the following table as weighted-averages:

	Benefit Obligation		Net Cost
	2012	2011	2012	2011	2010
Discount rate	4.0%	4.7%	4.6%	5.4%	5.9%
Salary scale	4.2%	4.3%	4.3%	4.4%	4.4%
Expected return on plan assets	-	-	7.7%	7.9%	8.0%

In determining the expected return on plan assets, we consider the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes, and economic and other indicators of future performance. In addition, we may consult with and consider the opinions of financial and other professionals in developing appropriate capital market assumptions. Return projections are also validated using a simulation model that incorporates yield curves, credit spreads and risk premiums to project long-term prospective returns.

The plans' investment management objectives include maintaining an adequate level of diversification, reducing interest rate and market risk, and providing adequate liquidity to meet immediate and future benefit payment requirements. The overall investment strategy targets a mix of 65% growth seeking assets and 35% income generating assets using a wide diversification of asset types, fund strategies and investment managers. The growth seeking allocation consists of global public equities in developed and emerging countries, private equity, real estate and balanced market risk strategies. Within public equities, 9% of the total investment portfolio is an enhanced equity strategy that invests in publicly traded equity and fixed income securities, derivatives and foreign currency. Investments in private equity are primarily via limited partnership interests in buy-out strategies with smaller allocations to distressed debt funds. The real estate strategy is principally concentrated in directly held U.S. core investments with some smaller investments in international, value-added and opportunistic strategies. Within the income generating assets, the fixed income portfolio is mainly a broadly diversified portfolio of corporate bonds.

The plans have continued their pension risk management techniques designed to reduce the plan's interest rate risk. More specifically, the plans have incorporated liability hedging programs that include the adoption of a risk reduction objective as part of the long-term investment strategy. Under this objective the interest rate hedge is dynamically increased as funded status improves. The hedging programs incorporate a range of assets and investment tools, each with ranging interest rate sensitivity. The investment portfolios are currently hedging 40% to 50% of the interest rate sensitivity of the pension plan liabilities.

Our common stock represents approximately 3% and 4% of total plan assets at December 31, 2012 and 2011, respectively. We review our assets at least quarterly to ensure we are within the targeted asset allocation ranges and, if necessary, asset balances are adjusted back within target allocations. We employ a broadly diversified investment manager structure that includes diversification by active and passive management, style, capitalization, country, sector, industry and number of investment managers.

Quoted market prices are used to value investments when available. Investments in securities traded on exchanges, including listed futures and options, are valued at the last reported sale prices on the last business day of the year or, if not available, the last reported bid prices. Fixed income securities are primarily measured using a market approach pricing methodology, where observable prices are obtained by market transactions involving identical or comparable securities of issuers with similar credit ratings. Mortgages have been valued on the basis of their future principal and interest payments discounted at prevailing interest rates for similar investments. Investment contracts are valued at fair value by discounting the related cash flows based on current yields of similar instruments with comparable durations. Real estate investments are valued on a quarterly basis using discounted cash flow models which consider long-term lease estimates, future rental receipts and estimated residual values. Valuation estimates are supplemented by third-party appraisals on an annual basis.

Private equity limited partnerships are valued quarterly using discounted cash flows, earnings multiples and market multiples. Valuation adjustments reflect changes in operating results, financial condition, or prospects of the applicable portfolio company. Over-the-counter securities and government obligations are valued at the bid prices or the average of the bid and ask prices on the last business day of the year from published sources or, if not available, from other sources considered reliable, generally broker quotes. Temporary cash investments are stated at cost, which approximates fair value.

Estimated Future Contributions and Benefit Payments

We expect to make contributions of approximately $200 million to our foreign defined benefit pension plans in 2013. Although we are not required to make contributions to our domestic defined benefit pension plans through the end of 2013, we may elect to make discretionary contributions in 2013. Contributions do not reflect benefits to be paid directly from corporate assets.

Benefit payments, including amounts to be paid from corporate assets, and reflecting expected future service, as appropriate, are expected to be paid as follows: $1,657 million in 2013, $1,654 million in 2014, $1,724 million in 2015, $1,793 million in 2016, $1,880 million in 2017, and $10,442 million from 2018 through 2022.

Postretirement Benefit Plans. We sponsor a number of postretirement benefit plans that provide health and life benefits to eligible retirees. Such benefits are provided primarily from domestic plans, which comprise approximately 88% of the benefit obligation. The postretirement plans are primarily unfunded. Assets in funded plans are primarily invested in cash and cash equivalents.

As part of our acquisition of Goodrich on July 26, 2012, we assumed approximately $328 million of postretirement projected benefit obligations.

We modified the postretirement medical benefits provided to legacy Goodrich salaried employees by eliminating any company subsidy for retirements that occur after January 31, 2014. This resulted in a $16 million reduction in the projected benefit obligation as of July 26, 2012.

The components of net periodic benefit cost are as follows:

The estimated amounts that will be amortized from accumulated other comprehensive loss into net periodic benefit cost in 2013 include actuarial net gains of $4 million and prior service credit of $11 million.

Major assumptions used in determining the benefit obligation and net cost for postretirement plans are presented in the following table as weighted-averages:

	Benefit Obligation		Net Cost
	2012	2011	2012	2011	2010

Effect on postretirement benefit obligation		71		(60)

Estimated Future Benefit Payments

Benefit payments, including net amounts to be paid from corporate assets and reflecting expected future service, as appropriate, are expected to be paid as follows: $100 million in 2013, $98 million in 2014, $95 million in 2015, $89 million in 2016, $83 million in 2017, and $357 million from 2018 through 2022.

Multiemployer Benefit Plans. We contribute to various domestic and foreign multiemployer defined benefit pension plans. The risks of participating in these multiemployer plans are different from single-employer plans in that assets contributed are pooled and may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. Lastly, if we choose to stop participating in some of our multiemployer plans, we may be required to pay those plans a withdrawal liability based on the underfunded status of the plan.

Our participation in these plans for the annual periods ended December 31 is outlined in the table below. Unless otherwise noted, the most recent Pension Protection Act (PPA) zone status available in 2012 and 2011 is for the plan's year-end at June 30, 2011, and June 30, 2010, respectively. The zone status is based on information that we received from the plan and is certified by the plan's actuary. Our significant plan is in the green zone which represents at least 80 percent funded and does not require a financial improvement plan (FIP) or a rehabilitation plan (RP).

(Dollars in millions)		Pension Protection Act Zone Status		FIP/RP Status	Contributions							Expiration Date of Collective-Bargaining Agreement

Other funds						36		38		35

					$	99	$	94	$	90

For the plan years ended June 30, 2011 and 2010, respectively, we were listed in the National Elevator Industry Pension Plan's Forms 5500 as providing more than 5% of the total contributions for the plan. At the date these financial statements were issued, Forms 5500 were not available for the plan year ending June 30, 2012.

In addition, we participate in several multiemployer arrangements that provide postretirement benefits other than pensions, with the National Elevator Industry Health Benefit Plan being the most significant. These arrangements generally provide medical and life benefits for eligible active employees and retirees and their dependents. Contributions to multiemployer plans that provide postretirement benefits other than pensions were $11 million, $10 million and $10 million for 2012, 2011 and 2010, respectively.

Stock-based Compensation. We have long-term incentive plans authorizing various types of market and performance based incentive awards that may be granted to officers and employees. Our Long Term Incentive Plan (LTIP) was initially approved on April 13, 2005 and amended in 2011 to increase the maximum number of shares available for award under the LTIP to 119 million shares. All equity-based compensation awards are made exclusively through the LTIP. As of December 31, 2012, approximately 44 million shares remain available for awards under the LTIP. The LTIP does not contain an aggregate annual award limit. We expect that the shares awarded on an annual basis will range from 1% to 1.5% of shares outstanding. The LTIP will expire after all shares have been awarded or April 30, 2017, whichever is sooner.

Under all long-term incentive plans, the exercise price of awards is set on the grant date and may not be less than the fair market value per share on that date. Generally, stock appreciation rights and stock options have a term of ten years and a minimum three-year vesting period. In the event of retirement, awards held for more than one year become vested and exercisable. LTIP awards with performance-based vesting generally have a minimum three-year vesting period and vest based on performance against pre-established metrics. In the event of retirement, vesting for awards held more than one year does not accelerate, but such awards remain eligible to vest as scheduled based on actual performance relative to target metrics. We have historically repurchased shares of our common stock in an amount at least equal to the number of shares issued under our equity compensation arrangements and will continue to evaluate this policy in conjunction with our overall share repurchase program.

We measure the cost of all share-based payments, including stock options, at fair value on the grant date and recognize this cost in the statement of operations. For the years ended December 31, 2012, 2011 and 2010, $210 million, $221 million and $148 million, respectively, of compensation cost was recognized in operating results. The associated future income tax benefit recognized was $76 million, $75 million and $47 million for the years ended December 31, 2012, 2011 and 2010, respectively.

For the years ended December 31, 2012, 2011 and 2010, the amount of cash received from the exercise of stock options was $381 million, $226 million and $386 million, respectively, with an associated tax benefit realized of $111 million, $101 million and $139 million, respectively. In addition, for the years ended December 31, 2012, 2011 and 2010, the associated tax benefit realized from the vesting of performance share units was $15 million, $19 million and $20 million, respectively. Also, in accordance with the Compensation – Stock Compensation Topic of the FASB ASC, for the years ended December 31, 2012, 2011 and 2010, $67 million, $81 million and $94 million, respectively, of certain tax benefits have been reported as operating cash outflows with corresponding cash inflows from financing activities.

At December 31, 2012, there was $185 million of total unrecognized compensation cost related to non-vested equity awards granted under long-term incentive plans. This cost is expected to be recognized ratably over a weighted-average period of 1.9 years.

A summary of the transactions under all long-term incentive plans for the year ended December 31, 2012 follows:

The weighted-average grant date fair value of stock options and stock appreciation rights granted during 2012, 2011 and 2010 was $19.32, $20.26 and $17.86, respectively. The weighted-average grant date fair value of performance share units, which vest upon achieving certain performance metrics, granted during 2012, 2011, and 2010 was $82.15, $87.65 and $78.73, respectively. The total fair value of awards vested during the years ended December 31, 2012, 2011 and 2010 was $187 million, $170 million and $172 million, respectively. The total intrinsic value (which is the amount by which the stock price exceeded the exercise price on the date of exercise) of stock options and stock appreciation rights exercised during the years ended December 31, 2012, 2011 and 2010 was $370 million, $336 million and $446 million, respectively. The total intrinsic value (which is the stock price at vesting) of performance share units vested was $46 million, $59 million and $62 million during the years ended December 31, 2012, 2011 and 2010, respectively.

The following table summarizes information about equity awards outstanding that are vested and expected to vest and equity awards outstanding that are exercisable at December 31, 2012:

The fair value of each option award is estimated on the date of grant using a binomial lattice model. The following table indicates the assumptions used in estimating fair value for the years ended December 31, 2012, 2011 and 2010. Lattice-based option models incorporate ranges of assumptions for inputs, those ranges are as follows:

	2012	2011	2010
Expected volatility	30% - 35%	26% - 32%	24% - 28%
Weighted-average volatility	30%	26%	25%
Expected term (in years)	7.4 - 7.7	7.5 - 8.0	7.4 - 7.9
Expected dividends	2.3%	2.4%	2.7%
Risk-free rate	0.0% - 2.0%	0.1% - 3.5%	0.1% - 4.0%

Expected volatilities are based on the returns of our stock, including implied volatilities from traded options on our stock for the binomial lattice model. We use historical data to estimate equity award exercise and employee termination behavior within the valuation model. Separate employee groups and equity award characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time equity awards are expected to remain outstanding. The risk-free rate is based on the term structure of interest rates at the time of equity award grant.

Note 13: Restructuring and Other Costs

Note 13: Restructuring Costs

During 2012, we recorded net pre-tax restructuring costs totaling $614 million for new and ongoing restructuring actions. We recorded charges in the segments as follows:

(Dollars in millions)
Otis	$	164
UTC Climate, Controls & Security		143
Pratt & Whitney		96
UTC Aerospace Systems		115
Sikorsky		53
Eliminations and other		19
Restructuring costs recorded within continuing operations		590
Restructuring costs recorded within discontinued operations		24
Total	$	614

The net costs consist of $340 million recorded in cost of sales, $249 million in selling, general and administrative expenses, $1 million in other income, net, and $24 million in discontinued operations. As described below, these charges primarily relate to actions initiated during 2012 and 2011.

2012 Actions. During 2012, we initiated restructuring actions relating to ongoing cost reduction efforts, including workforce reductions and consolidation of manufacturing operations. We recorded net pre-tax restructuring costs totaling $576 million for restructuring actions initiated in 2012, consisting of $313 million in cost of sales, $236 million in selling, general and administrative expenses, $1 million in other income, net, and $26 million in discontinued operations. Additionally, due to the Goodrich acquisition, we assumed restructuring accruals totaling $19 million.

We expect the actions that were initiated in 2012 to result in net workforce reductions of approximately 7,000 hourly and salaried employees, the exiting of approximately 2.6 million net square feet of facilities and the disposal of assets associated with exited facilities. As of December 31, 2012, we have completed, with respect to the actions initiated in 2012, net workforce reductions of approximately 4,000 employees and 750,000 net square feet of facilities have been exited. We are targeting to complete in 2013 the majority of the remaining workforce and all facility related cost reduction actions initiated in 2012. No specific plans for significant other actions have been finalized at this time.

The following table summarizes the accrual balances and utilization by cost type for the 2012 restructuring actions:

(Dollars in millions)	Severance		Asset Write-Downs		Facility Exit, Lease Termination and Other Costs		Total

Total	$	681	$	(576)	$	105

2011 Actions. During 2012, we recorded net pre-tax restructuring costs totaling $53 million for restructuring actions initiated in 2011, consisting of $33 million in cost of sales, $19 million in selling, general and administrative expenses, and $1 million in discontinued operations. The 2011 actions relate to ongoing cost reduction efforts, including workforce reductions and the consolidation of field operations.

As of December 31, 2012, we have completed net workforce reductions of approximately 4,200 employees of an expected 4,900, and have exited 200,000 net square feet of facilities of an expected 2 million net square feet. The remaining workforce and facility reduction actions are targeted for completion during 2013.

The following table summarizes the restructuring accrual balances and utilization by cost type for the 2011 programs:

Note 14: Financial Instruments

12 Months Ended

Dec. 31, 2012

Notes to Consolidated Financial Statements [Abstract]

Note 14: 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 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 deemed 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, 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 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 $11.8 billion and $10.4 billion at December 31, 2012 and 2011, respectively.

Additional information pertaining to foreign exchange and hedging activities is included in Note 1.

We enter into transactions that are subject to enforceable master netting arrangements or other similar agreements with various counterparties. However, we have not elected to offset multiple contracts with a single counterparty and, as a result, the fair value of the derivative instruments in a loss position is not offset against the fair value of derivative instruments in a gain position.

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

		December 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	$	48	$	47	$	69	$	40
	Other assets		30		3		3		2
			78		50		72		42
Total Asset Derivative Contracts				$	128			$	114

Balance Sheet Liability Locations:
	Accrued liabilities	$	10	$	136	$	81	$	40
	Other long-term liabilities		1		2		43		1
			11		138		124		41
Total Liability Derivative Contracts				$	149			$	165

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

	December 31,
(Dollars in millions)	2012		2011
Gain (loss) recorded in Accumulated other comprehensive loss	$	88	$	(46)
Gain reclassified from Accumulated other comprehensive loss into Product sales (effective portion)		31		96

Assuming current market conditions continue, a $40 million pre-tax gain 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 December 31, 2012, all derivative contracts accounted for as cash flow hedges mature by December 2015.

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

	December 31,
(Dollars in millions)		2012		2011
Loss recognized in Other income, net	$	(120)	$	(39)

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 FASB ASC Topic “Fair Value Measurements and Disclosures.” 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 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 FASB ASC Topic “Fair Value Measurements and Disclosure” establishes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, including interest rates, yield curves and credit risks, or inputs that are derived principally from or corroborated by observable market data through correlation. Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. A financial asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2012 and 2011:

(Dollars in millions)		Total Carrying Value at December 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	$	781	$	781	$	-	$	-
	Derivative assets		128		-		128		-
	Derivative liabilities		(149)		-		(149)		-

Nonrecurring fair value measurements:
	Equity method investments		432		-		432		-
	Business dispositions		84		-		84		-
	During 2012, we recorded net gains on nonrecurring fair value measurements of approximately $157 million within Other income, net from UTC Climate, Controls & Security’s ongoing portfolio transformation efforts including the integration of the legacy UTC Fire & Security businesses with the legacy Carrier businesses. These net gains include approximately $357 million from the sales of controlling interests in manufacturing and distribution joint ventures in Asia and Canada, of which approximately $272 million was non-cash. These gains were partially offset by $168 million of other-than-temporary impairment charges related to business dispositions and a $32 million loss on the disposition of the U.S. UTC Fire & Security branch operations. In addition, we recorded a $34 million gain on the fair market measurement of the Company's previously held interest in Goodrich.

(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 a non-cash other-than-temporary impairment charge 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 date 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 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 December 31, 2012, there were no significant transfers in and out of Level 1 and Level 2.

As of December 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 at December 31, 2012 and 2011:

	December 31, 2012				December 31, 2011

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

Long-term debt (excluding capitalized leases)		(25,606)		-		(25,548)		(58)
Long-term liabilities		(167)		-		(167)		-

Valuation Techniques. Our long-term receivables and customer financing notes receivable include our commercial and aerospace long-term trade, government and other receivables, leases, and notes receivable. Our long-term liabilities include our aerospace long-term customer payments. Our long-term receivables, customer financing notes receivable and long-term liabilities are measured at fair value using an income approach based on the present value of the contractual, promised or most likely cash flows discounted at observed or estimated market rates for comparable assets or liabilities that are traded in the market. Based on these inputs, long-term receivables, customer financing notes receivable and long-term liabilities 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 commercial aerospace financing and other contractual commitments totaling approximately $10.9 billion at December 31, 2012, which now include approximately $5.8 billion of IAE commitments, related to commercial aircraft and certain contractual rights to provide product on new aircraft platforms. We had commercial aerospace financing and other contractual commitments of approximately $3.0 billion at December 31, 2011. 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 Consolidated Financial Statements [Abstract]

Note 15: Credit Quality of Long-Term Receivables

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.

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 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 Consolidated Balance Sheet. The following table summarizes the balance by class of aerospace long-term receivables as of December 31, 2012 and 2011:

(Dollars in millions)	December 31, 2012		December 31, 2011
Long-term trade accounts receivable	$	593	$	204
Notes and leases receivable		584		365
Total long-term receivables	$	1,177	$	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 December 31, 2012 and 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 years ended December 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		1		25
Charge-offs		-		-
Recoveries		(5)		(9)
Other		(6)		12
Ending balance of the reserve for credit losses and exposure: individually evaluated for impairment as of December 31	$	60	$	70
Ending balance of long-term receivables: individually evaluated for impairment as of December 31	$	1,177	$	569

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 December 31, 2012 and 2011:

______________

* Represents IAE's gross obligation; at December 31, 2011 our proportionate share of IAE's obligations was 33%. As disclosed in Note 2, on June 29, 2012 Pratt & Whitney, Rolls-Royce, MTU and JAEC, completed a restructuring of their interests in IAE and as a result, we now consolidate IAE.

We also have obligations arising from sales of certain businesses and assets, including those from representations and warranties and related indemnities for environmental, health and safety, tax and employment matters. The maximum potential payment related to these obligations is not a specified amount as a number of the obligations do not contain financial caps. The carrying amount of liabilities related to these obligations was $144 million and $138 million at December 31, 2012 and 2011, respectively. For additional information regarding the environmental indemnifications, see Note 18.

We accrue for costs associated with guarantees 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, and where no amount within a range of estimates is more likely, the minimum is accrued. In accordance with the FASB ASC Topic ”Guarantees” of FASB ASC, we record a liability for the fair value of such guarantees in the balance sheet.

We provide service and warranty policies on our products and extend performance and operating cost guarantees beyond our normal service and warranty policies on some of our products, particularly commercial aircraft engines. In addition, we incur discretionary costs to service our products in connection with specific product performance issues. Liabilities for performance and operating cost guarantees are based upon future product performance and durability, and are largely estimated based upon historical experience. Adjustments are made to accruals as claim data and historical experience warrant. The changes in the carrying amount of service and product warranties and product performance guarantees for the years ended December 31, 2012 and 2011 are as follows:

(Dollars in millions)	2012		2011
Balance as of January 1	$	1,468	$	1,136
Warranties and performance guarantees issued		325		475
Settlements made		(277)		(440)
Other		(184)		297
Balance as of December 31	$	1,332	$	1,468

The decrease in the above table in “Other” during the year ended December 31, 2012 primarily reflects a decrease for Clipper warranty reserves as a result of the sale of the company, partially offset by an increase from the Goodrich acquisition. See Note 3 and Note 2, respectively, for further discussion. The increase reflected in “Other” during the year ended December 31, 2011 primarily reflected the impact of finalizing purchase accounting on the original acquisition of Clipper.

Notes to Consolidated Financial Statements [Abstract]

Note 17: Collaborative Arrangements

In view of the risks and costs associated with developing new engines, Pratt & Whitney has entered into certain collaboration arrangements in which sales, costs and risks are shared. 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 collaborators 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 December 31, 2012, the collaborators' interests in all commercial engine programs ranged from 14% 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 collaborators exceed a 31% share in an individual program.

On June 29, 2012, Pratt & Whitney, Rolls-Royce, MTU, and JAEC, participants in the IAE collaboration, completed a restructuring of their interests in IAE. Under the terms of the agreement, Rolls-Royce sold its ownership and collaboration interests in IAE to Pratt & Whitney, while also entering into an agreement to license its V2500 intellectual property to Pratt & Whitney. In exchange for the increased ownership and collaboration interests and intellectual property license, Pratt & Whitney paid Rolls-Royce $1.5 billion at closing with additional payments due to Rolls-Royce conditional upon each hour flown by V2500-powered aircraft in service at the closing date of the purchase from Rolls-Royce during the fifteen year period following closing of the purchase. The collaboration interest and intellectual property licenses are reflected as intangible assets and will be amortized in relation to the economic benefits received over the remaining estimated 30 year life of the V2500 program. Rolls-Royce will continue to support the program as a strategic supplier for the V2500 engine and continue to manufacture parts and assemble engines. Pratt & Whitney entered into a collaboration arrangement with MTU with respect to a portion of the acquired collaboration interest in IAE for consideration of approximately $233 million with additional payments due to Pratt & Whitney in the future. As a result of these transactions, Pratt & Whitney holds a 61% net interest in the collaboration and a 49.5% ownership interest in IAE. Please see Note 2 for further discussion of changes in the IAE collaboration arrangement.

The following table illustrates the income statement classification and amounts attributable to transactions arising from the collaborative arrangements between participants for each period presented:

(Dollars in millions)		2012		2011		2010
Collaborator share of sales:
	Cost of products sold	$	1,295	$	963	$	850

Note 18: Contingent Liabilities

Dec. 31, 2012

Notes to Consolidated Financial Statements [Abstract]

Note 18: Contingent Liabilities

Leases. We occupy space and use certain equipment under lease arrangements. Rental commitments of $2,486 million at December 31, 2012 under long-term non-cancelable operating leases are payable as follows: $646 million in 2013, $510 million in 2014, $378 million in 2015, $255 million in 2016, $158 million in 2017 and $539 million thereafter. Rent expense was $457 million in 2012, $453 million in 2011 and $445 million in 2010.

Additional information pertaining to commercial aerospace rental commitments is included in Note 5 to the Consolidated Financial Statements.

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. As described in Note 1 to the Consolidated Financial Statements, we have accrued for the costs of environmental remediation activities and periodically reassess these amounts. We believe that the likelihood of incurring losses materially in excess of amounts accrued is remote. At December 31, 2012, we had $847 million reserved for environmental remediation. Additional information pertaining to environmental matters is included in Note 1 to the Consolidated Financial Statements.

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 involved substantial amounts. We have made voluntary refunds in those cases we believe appropriate, have settled some allegations and continue to litigate certain 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 accrued the minimum amount.

As previously disclosed, the U.S. 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 its 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 trial court for further proceedings.

On June 18, 2012, the trial court found that Pratt & Whitney had breached other obligations imposed by common law based on the same conduct with respect to which the court previously found liability under the False Claims Act. Under the common law claims, the U.S. Air Force may seek damages for events occurring before March 3, 1989, which are not recoverable under the False Claims Act. Further proceedings at the trial court will determine the damages, if any, relating to the False Claims Act and common law claims. The government continues to seek damages of $624 million, plus interest. Pratt & Whitney continues to contend that the government suffered no actual damages. The parties have submitted briefs and await a decision from the trial court. Should the government ultimately prevail, the outcome of this matter could result in a material adverse 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 $94 million (including interest through December 31, 2012). We believe this claim is without merit and Sikorsky filed an appeal in December 2009 with the U.S. Court of Federal Claims. Trial in the matter concluded in January 2013 and we await a decision from the court. 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.

As previously disclosed, UTC has been involved in administrative review proceedings with the German Tax Office concerning €203 million (approximately $270 million) of tax benefits that we have claimed related to a 1998 reorganization of the corporate structure of Otis operations in Germany. A portion of these tax benefits were disallowed by the local German Tax Office on July 5, 2012, as a result of the audit of tax years 1999 to 2000. The legal and factual issues relating to the denial of the tax benefits center on the interpretation and application of a German tax law. On August 3, 2012, the Company filed suit in the local German tax court and intends to litigate vigorously the matter to conclusion. We do not believe the resolution of this matter will have a material adverse effect on our results of operations, cash flows or financial condition.

Other. Except as otherwise noted, we do not believe that resolution of any of the above matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition.

As described in Note 16 to the Consolidated Financial Statements, 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.

We have accrued for environmental investigatory, remediation, operating and maintenance costs, performance guarantees and other litigation and claims based on our estimate of the probable outcome of these matters. While it is possible that the outcome of these matters may differ from the recorded liability, we believe that resolution of these matters will not have a material impact on our competitive position, results of operations, cash flows or financial condition.

We also have other commitments and contingent liabilities related to legal proceedings, self-insurance programs and matters arising out of the normal course of business. 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.

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. 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.

Note 1: Summary of Accounting Principles (Policy)	12 Months Ended
Note 1: Summary of Accounting Principles (Policy)	Dec. 31, 2012
Summary Of Accounting Principles [Abstract]
Consolidation Policy [Text Block]	Consolidation. The Consolidated Financial Statements include the accounts of United Technologies Corporation (UTC) and its controlled subsidiaries. Intercompany transactions have been eliminated.
Cash And Cash Equivalents Policy [Text Block]	Cash and Cash Equivalents. Cash and cash equivalents includes cash on hand, demand deposits and short-term cash investments that are highly liquid in nature and have original maturities of three months or less.
Cash And Cash Equivalents Restricted Cash And Cash Equivalents Policy	On occasion, we are required to maintain cash deposits with certain banks with respect to contractual obligations related to acquisitions or divestitures or other legal obligations. As of December 31, 2012 and 2011, the amount of such restricted cash was approximately $35 million and $37 million, respectively and is included in Other assets, current.
Receivables Policy [Text Block]	Accounts Receivable. Current and long-term accounts receivable include retainage of $172 million and $154 million and unbilled receivables of $1,363 million and $1,060 million as of December 31, 2012 and 2011, respectively. Retainage represents amounts that, pursuant to the applicable contract, are not due until project completion and acceptance by the customer. Unbilled receivables represent revenues that are not currently billable to the customer under the terms of the contract. These items are expected to be collected in the normal course of business. Long-term accounts receivable are included in Other assets in the Consolidated Balance Sheet.
Marketable Securities Available For Sale Securities Policy	Marketable Equity Securities. Equity securities that have a readily determinable fair value and that we do not intend to trade are classified as available-for-sale and carried at fair value. Unrealized holding gains and losses are recorded as a separate component of shareowners' equity, net of deferred income taxes.
Inventory Policy Text Block	Inventories and Contracts in Progress. Inventories and contracts in progress are stated at the lower of cost or estimated realizable value and are primarily based on first-in, first-out (FIFO) or average cost methods; however, certain UTC Aerospace Systems and UTC Climate, Controls & Security entities use the last-in, first-out (LIFO) method. If inventories that were valued using the LIFO method had been valued under the FIFO method, they would have been higher by $139 million and $144 million at December 31, 2012 and 2011, respectively. Costs accumulated against specific contracts or orders are at actual cost. Inventory in excess of requirements for contracts and current or anticipated orders have been reserved as appropriate. Manufacturing costs are allocated to current production and firm contracts.
Property Plant And Equipment Policy [Text Block]	Fixed Assets. Fixed assets are stated at cost. Depreciation is recorded over the fixed assets' useful lives using the straight-line method.
Goodwill And Intangible Assets Policy [Text Block]	Goodwill and Intangible Assets. Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill and intangible assets deemed to have indefinite lives are not amortized. Goodwill and indefinite-lived intangible assets are subject to annual impairment testing using the guidance and criteria described in the FASB ASC Topic “Intangibles – Goodwill and Other” . This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. During 2012 we early-adopted the FASB Accounting Standards Update (ASU) No. 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment” in connection with the performance of our annual goodwill and indefinite-lived intangible assets impairment test. This ASU intends to align impairment testing guidance among indefinite-lived asset categories. This ASU allows an assessment based on qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired prior to determining whether it is necessary to perform the quantitative impairment test in accordance with FASB ASC Subtopic 350-30, “Intangibles - Goodwill and Other - General Intangibles Other than Goodwill.” During 2012, we recorded pre-tax goodwill impairment charges of approximately $360 million and $590 million related to Pratt & Whitney Rocketdyne (Rocketdyne) and Clipper Windpower (Clipper), respectively. 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. During 2011 and 2010, we did not record any significant impairments to the carrying value of goodwill or indefinite-lived intangible assets. Intangible assets consist of service portfolios, patents, trademarks/tradenames, customer relationships and other intangible assets including a collaboration asset established in connection with the restructuring of IAE International Aero Engines AG (IAE) as discussed further in Note 2. Also included within other intangible assets are commercial aerospace payments made to secure certain contractual rights to provide product on new aircraft platforms. Payments made on these contractual commitments are to be amortized as the related OEM and Aftermarket units are delivered. Useful lives of finite-lived intangible assets are estimated based upon the nature of the intangible asset and the industry in which the intangible asset is used. These intangible assets are amortized based on the pattern in which the economic benefits of the intangible assets are consumed. For both our commercial aerospace collaboration assets and exclusivity arrangements, the pattern of economic benefit generally results in lower amortization during the development period with increasing amortization as programs enter full rate production and aftermarket cycles. If a pattern of economic benefit cannot be reliably determined, a straight-line amortization method is used. The range of estimated useful lives is as follows: Collaboration asset 30 years Customer relationships and related programs 2 to 32 years Purchased service contracts 5 to 30 years Patents & trademarks 3 to 40 years Exclusivity assets 3 to 25 years
Impairment Or Disposal Of Long Lived Assets Policy [Text Block]	Other Long-Lived Assets. We evaluate the potential impairment of other long-lived assets when appropriate. If the carrying value of other long-lived assets exceeds the sum of the undiscounted expected future cash flows, the carrying value is written down to fair value. During the years ended December 31, 2012 and 2011, we had certain non-recurring fair value measurements resulting in impairment charges of $168 million and $66 million, respectively. See Note 14. Additionally, in 2012 we recorded pre-tax net asset impairment charges of approximately $179 million related to UTC Power in discontinued operations. The impairment charge at UTC Power results from the disposition of the business before the benefits of technology investments were fully realized.
Income Tax Policy [Text Block]	Income Taxes. 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 expense has also been recognized. We recognize accrued interest related to unrecognized tax benefits in interest expense. Penalties, if incurred, would be recognized as a component of income tax expense.
Revenue Recognition	Revenue Recognition. Sales under government and commercial fixed-price contracts and government fixed-price-incentive contracts are recorded at the time deliveries are made or, in some cases, on a percentage-of-completion basis. Sales under cost-reimbursement contracts are recorded as work is performed. Sales for elevators, escalators, installation and modernization contracts are accounted for under the percentage-of-completion method. Losses, if any, on long-term contracts are provided for when anticipated. Loss provisions on original equipment contracts are recognized to the extent that estimated inventoriable manufacturing, engineering, product warranty and product performance guarantee costs, as appropriate, exceed the projected revenue from the products contemplated under the contractual arrangement. For new commitments, we generally record loss provisions at the earlier of contract announcement or contract signing except for certain requirements contracts under which losses are recorded upon receipt of the purchase order. For existing commitments, anticipated losses on contracts are recognized in the period in which losses become evident. Products contemplated under contractual arrangement include products purchased under contract and, in the large commercial engine and wheels and brakes businesses, future highly probable sales of replacement parts required by regulation that are expected to be purchased subsequently for incorporation into the original equipment. Revenue projections used in determining contract loss provisions are based upon estimates of the quantity, pricing and timing of future product deliveries. Losses are generally recognized on shipment to the extent that inventoriable manufacturing costs, estimated warranty costs and product performance guarantee costs, as appropriate, exceed revenue realized. Contract accounting requires estimates of future costs over the performance period of the contract as well as estimates of award fees and other sources of revenue. These estimates are subject to change and result in adjustments to margins on contracts in progress. The extent of progress toward completion on our long-term commercial aerospace equipment and helicopter contracts is measured using units of delivery. In addition, we use the cost-to-cost method for elevator and escalator sales, installation and modernization contracts in the commercial businesses. For long-term aftermarket contracts, revenue is recognized over the contract period in proportion to the costs expected to be incurred in performing services under the contract. We review our cost estimates on significant contracts on a quarterly basis, and for others, no less frequently than annually or when circumstances change and warrant a modification to a previous estimate. We record changes in contract estimates using the cumulative catch-up method in accordance with the Revenue Recognition Topic of the FASB ASC. In 2012, we recorded a $157 million charge on the CH-148 Canadian Maritime Helicopter program resulting from ongoing program delays.
Revenue Recognition Sales Of Services	Service sales, representing aftermarket repair and maintenance activities, are recognized over the contractual period or as services are performed. In the commercial businesses, revenue is generally recognized on a straight-line basis. In the aerospace businesses, revenue is generally recognized in proportion to cost.
Collaborative Arrangement Accounting Policy	Sales generated from engine programs, spare parts sales, and aftermarket business under collaboration arrangements are recorded as earned in our financial statements. Amounts attributable to our collaborators for their share of revenues 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 a collaborator's share of program costs is recorded as a reduction of the related expense item at that time.
Research and Development Expense, Policy [Text Block]	Research and Development. Research and development costs not specifically covered by contracts and those related to the company sponsored share of research and development activity in connection with cost-sharing arrangements are charged to expense as incurred. Government research and development support, not associated with specific contracts, is recorded as a reduction to research and development expense in the period earned. Repayment, if any, is in the form of future royalties and is conditioned upon the achievement of certain financial targets including specific aircraft engine sales, total aircraft engine sales volume and total year-over-year sales growth of the entity receiving the government funding. Given the conditional and uncertain nature of any repayment obligations, royalty expense is typically recorded only upon engine shipment or is otherwise accrued monthly based upon the forecasted impact for the current year. The cumulative funding received under existing relationships has been approximately $2.0 billion of which approximately $450 million has been repaid to date in the form of royalties. Research and development costs incurred under contracts with customers are included as a contract cost and reported as a component of cost of products sold when revenue from such contracts is recognized. Research and development costs in excess of contractual consideration is expensed as incurred.
Foreign Currency Transactions And Translations Policy [Text Block]	Foreign Exchange and Hedging Activity. We conduct business in many different currencies and, accordingly, are subject to the inherent risks associated with foreign exchange rate movements. The financial position and results of operations of substantially all of our foreign subsidiaries are measured using the local currency as the functional currency. Foreign currency denominated assets and liabilities are translated into U.S. Dollars at the exchange rates existing at the respective balance sheet dates, and income and expense items are translated at the average exchange rates during the respective periods. The aggregate effects of translating the balance sheets of these subsidiaries are deferred as a separate component of shareowners' equity.
Derivatives Policy [Text Block]	We have used derivative instruments, including swaps, forward contracts and options, to help manage certain foreign currency, interest rate and commodity price exposures. Derivative instruments are viewed as risk management tools by us and are not used for trading or speculative purposes. Derivatives used for hedging purposes may be designated and effective as a hedge of the identified risk exposure at the inception of the contract. All derivative instruments are recorded on the balance sheet at fair value. Derivatives used to hedge foreign-currency-denominated balance sheet items are reported directly in earnings along with offsetting transaction gains and losses on the items being hedged. Derivatives used to hedge forecasted cash flows associated with foreign currency commitments or forecasted commodity purchases may be accounted for as cash flow hedges, as deemed appropriate. Gains and losses on derivatives designated as cash flow hedges are recorded in other comprehensive income and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions. The ineffective portion of all hedges, if any, is recognized currently in earnings. Additional information pertaining to foreign currency forward contracts is included in Note 14.
Environmental Costs Policy	Environmental. Environmental investigatory, remediation, operating and maintenance costs are accrued 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, the minimum is accrued. 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. Liabilities with fixed or reliably determinable future cash payments are discounted. Accrued environmental liabilities are not reduced by potential insurance reimbursements.
Asset Retirement Obligations Policy	Asset Retirement Obligations. We record the fair value of legal obligations associated with the retirement of tangible long-lived assets in the period in which it is determined to exist, if a reasonable estimate of fair value can be made. Upon initial recognition of a liability, we capitalize the cost of the asset retirement obligation by increasing the carrying amount of the related long-lived asset. Over time, the liability is increased for changes in its present value and the capitalized cost is depreciated over the useful life of the related asset. We have determined that conditional legal obligations exist for certain of our worldwide owned and leased facilities related primarily to building materials. As of December 31, 2012 and 2011, the outstanding liability for asset retirement obligations was $174 million and $164 million, respectively.
Pension And Other Postretirement Plans Pensions Policy	Pension and Postretirement Obligations. Guidance under the FASB ASC Topic Compensation – Retirement Benefits requires balance sheet recognition of the overfunded or underfunded status of pension and postretirement benefit plans. Under this guidance, actuarial gains and losses, prior service costs or credits, and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized in other comprehensive income, net of tax effects, until they are amortized as a component of net periodic benefit cost.
Revenue Recognition, Incentives [Policy Text Block]	UTC Climate, Controls & Security customarily offers its customers incentives to purchase products to ensure an adequate supply of its products in the distribution channels. The principal incentive program provides reimbursements to distributors for offering promotional pricing for our products. We account for incentive payments made as a reduction in sales.

	During 2012, we recorded net gains on nonrecurring fair value measurements of approximately $157 million within Other income, net from UTC Climate, Controls & Security’s ongoing portfolio transformation efforts including the integration of the legacy UTC Fire & Security businesses with the legacy Carrier businesses. These net gains include approximately $357 million from the sales of controlling interests in manufacturing and distribution joint ventures in Asia and Canada, of which approximately $272 million was non-cash. These gains were partially offset by $168 million of other-than-temporary impairment charges related to business dispositions and a $32 million loss on the disposition of the U.S. UTC Fire & Security branch operations. In addition, we recorded a $34 million gain on the fair market measurement of the Company's previously held interest in Goodrich.

	During 2011, we recorded a non-cash other-than-temporary impairment charge 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 date the investment was deemed to be impaired.

Multiemployer Plans [Line Items]

Multiemployer Plans General Nature

We contribute to various domestic and foreign multiemployer defined benefit pension plans. The risks of participating in these multiemployer plans are different from single-employer plans in that assets contributed are pooled and may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. Lastly, if we choose to stop participating in some of our multiemployer plans, we may be required to pay those plans a withdrawal liability based on the underfunded status of the plan.

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.

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 U.S. 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 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 its 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.
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. In November 2010, the Sixth Circuit affirmed Pratt & Whitney’s liability under the False Claims Act and remanded the case to the trial court for further proceedings.
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 $94 million (including interest through December 31, 2012).
Loss Contingency Damages Sought	$94 million (including interest through December 31, 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. Trial in the matter concluded in January 2013 and we await a decision from the court. 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.
US Air Force Claim Against Pratt and Whitney [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	June 18, 2012
Loss Contingency Allegations	On June 18, 2012, the trial court found that Pratt & Whitney had breached other obligations imposed by common law based on the same conduct with respect to which the court previously found liability under the False Claims Act. Under the common law claims, the U.S. Air Force may seek damages for events occurring before March 3, 1989, which are not recoverable under the False Claims Act. Further proceedings at the trial court will determine the damages, if any, relating to the False Claims Act and common law claims. The government continues to seek damages of $624 million, plus interest.
Loss Contingency Damages Sought	$624 million
Loss Contingency Actions Taken By Plaintiff And Defendant	Pratt & Whitney continues to contend that the government suffered no actual damages. The parties have submitted briefs and await a decision from the trial court. Should the government ultimately prevail, the outcome of this matter could result in a material adverse 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.
German Tax Office Against Company [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	August 3, 2012
Loss Contingency Allegations	As previously disclosed, UTC has been involved in administrative review proceedings with the German Tax Office concerning €203 million (approximately $270 million) of tax benefits that we have claimed related to a 1998 reorganization of the corporate structure of Otis operations in Germany. A portion of these tax benefits were disallowed by the local German Tax Office on July 5, 2012, as a result of the audit of tax years 1999 to 2000. The legal and factual issues relating to the denial of the tax benefits center on the interpretation and application of a German tax law.
Loss Contingency Damages Sought	€203 million (approximately $270 million)
Loss Contingency Actions Taken By Defendant	On August 3, 2012, the Company filed suit in the local German tax court and intends to litigate vigorously the matter to conclusion. We do not believe the resolution of this matter will have a material adverse effect on our results of operations, cash flows or financial condition.
