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 prior year amounts to conform to current year presentation.

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, 2011 and 2010, the amount of such restricted cash was approximately $37 million and $75 million, respectively. At both December 31, 2011 and 2010, all restricted cash is included in current assets.

Accounts Receivable. Current and long-term accounts receivable include retainage of $154 million and $165 million and unbilled receivables of $1,060 million and $862 million as of December 31, 2011 and 2010, 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 Carrier 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 $144 million and $137 million at December 31, 2011 and 2010, 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 Intangibles – Goodwill and Other Topic of the FASB ASC. This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. We early adopted the FASB ASU No. 2011-08, “Testing Goodwill for Impairment,” in connection with the performance of our annual goodwill impairment test. Under ASU 2011-08, entities are provided with the option of first performing a qualitative assessment on none, some, or all of its reporting units to determine whether further quantitative impairment testing is necessary. An entity may also bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative impairment test. During 2011, 2010, and 2009, we were not required to record any significant impairments to the carrying value of goodwill or indefinite-lived intangible assets.

Intangible assets consist of service portfolios, patents and trademarks, customer relationships and other intangible assets. 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. Estimated useful lives of service portfolios generally range from 5 to 30 years. Estimated useful lives of patents and finite-lived trademarks generally range from 3 to 40 years. Estimated useful lives of customer relationships and other assets generally range from 2 to 32 years. These intangible assets are amortized based on the pattern in which the economic benefits of the intangible assets are consumed. If a pattern of economic benefit cannot be reliably determined, a straight-line amortization method is used. 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 units are delivered.

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, 2011 and 2010, we had certain non-recurring measurements resulting in impairment charges of $66 million and $245 million, respectively. See Note 13 to the Consolidated Financial Statements for additional information.

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 business, 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.

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 collaborative partners 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. 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.

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.

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 13 to the Consolidated Financial Statements.

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, 2011 and 2010, the outstanding liability for asset retirement obligations was $164 million and $189 million, respectively.

Pension and Postretirement Obligations. Guidance under the Compensation – Retirement Benefits Topic of the FASB ASC 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.

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

Business Acquisitions and Dispositions. Our investments in businesses in 2011, 2010 and 2009 totaled $372 million (including debt assumed of $15 million), $2.8 billion (including debt assumed of $39 million) and $703 million, respectively.

Our 2011 investments consisted of a number of smaller acquisitions in both the aerospace and commercial businesses. As a result of Sikorsky's contribution of a business into a new venture in the United Arab Emirates, we recognized a gain of approximately $73 million in the second quarter of 2011.

In November 2011, Carrier 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 Carrier's existing HVAC operations in the three countries and Midea's distribution entity. Midea owns 51% of the venture and Carrier 49%. This joint venture strengthens Carrier's global strategic relationship with Midea and expands the manufacturing and distribution of residential and light commercial HVAC systems in Brazil, Argentina, and Chile. Carrier recognized a gain of approximately $80 million in 2011 as a result of this transaction.

On October 12, 2011, Pratt & Whitney and Rolls-Royce plc (Rolls-Royce), a participant in the IAE collaboration, announced an agreement to restructure their interests in IAE. Under the terms of the agreement, Rolls-Royce will sell its interests in IAE and license its V2500 intellectual property in IAE to Pratt & Whitney for $1.5 billion plus an agreed payment contingent on each hour flown by V2500-powered aircraft in service at the closing date during the fifteen year period following closing of the transaction. Consummation of this restructuring is subject to regulatory approvals and other closing conditions. The acquisition of the additional interests in IAE will give Pratt & Whitney a controlling interest with approximately 66% ownership. Upon closing, we anticipate Pratt & Whitney will begin consolidating IAE. The acquisition of the additional interests in IAE and the intellectual property licenses will be reflected as intangible assets and amortized in relation to the economic benefits received over the projected remaining life of the V2500 program.

Also, on October 12, 2011, Pratt & Whitney and Rolls-Royce announced an agreement to form a new joint venture, in which each will hold an equal share, to develop new engines to power the next generation of 120 to 230 passenger mid-size aircraft that will replace the existing fleet of mid-size aircraft currently in service or in development. With this new joint venture, Pratt & Whitney and Rolls-Royce will focus on high-bypass ratio geared turbofan technology as well as collaborate on future studies of next generation propulsion systems. Pursuant to the agreement, the formation of this new venture is subject to regulatory approvals and other closing conditions, including completion of the restructuring of the parties' interests in IAE. We expect the restructuring of the parties' interests in IAE to be completed in mid-2012. The closing of the new joint venture may take a substantially longer period of time to complete.

On September 21, 2011, we announced an agreement to acquire Goodrich Corporation (Goodrich), a global supplier of systems and services to the aerospace and defense industry with 2010 sales of $7 billion. Under the terms of the agreement, Goodrich shareholders will receive $127.50 in cash for each share of Goodrich common stock they own at the time of the closing of the transaction. This equates to a total estimated enterprise value of $18.4 billion, including $1.9 billion in net debt to be assumed. We expect to finance the total $16.5 billion to be paid to Goodrich shareholders at the closing of the acquisition through a combination of short and long term debt, equity issuance and cash. We intend to maintain our strong existing credit rating and minimize future share count dilution on earnings per share by targeting the equity component to comprise no more than 25% of the total financing (excluding the amount of Goodrich net debt to be assumed). We are also evaluating the potential disposition of a number of our non-core businesses to generate cash and minimize the level of future debt or equity issuances. The transaction is subject to customary closing conditions, including regulatory approvals and Goodrich shareholder approval. We expect that this acquisition will close in mid-2012. Goodrich products include aircraft nacelles and interior systems, actuation and landing systems, and electronic systems. Once the acquisition is complete, Goodrich and Hamilton Sundstrand will be combined to form a new segment named UTC Aerospace Systems. This segment and our Pratt & Whitney segment will be separately reportable segments although they will both be included within the UTC Propulsion & Aerospace Systems organizational structure. We expect the increased scale, financial strength and complementary products of the new combined business will strengthen our position in the aerospace and defense industry. Further, we expect that this acquisition will enhance our ability to support our customers with more integrated systems.

During 2011, we recorded other-than-temporary impairment charges totaling $66 million on an equity investment held by UTC Fire & 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 Fire & Security segment, enhanced UTC Fire & 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 Fire & 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 completed the acquisition of Clipper Windpower Plc (Clipper), a publicly-held California-based wind turbine manufacturer. This investment is intended to expand our power generation portfolio and allow us to enter the wind power market by leveraging our expertise in blade technology, turbines and gearbox design. In the first half of 2010, we acquired a 49.9% equity stake in Clipper. In December 2010, we completed the acquisition of all the remaining shares of Clipper. The total cost of our investment in Clipper is approximately $385 million. In connection with this transaction, we recorded approximately $650 million of goodwill and identifiable intangible assets. Prior to the December 2010 purchase of the remaining shares of Clipper, we accounted for this investment under the equity method of accounting. During the quarter ended September 30, 2010, we recorded a $159 million other-than-temporary impairment charge on our investment in Clipper, in order to write-down our investment to market value as of September 30, 2010. This impairment is recorded within “Other income, net” on our Consolidated Statement of Operations. In December 2010, as a result of the acquisition of a controlling interest and the remaining shares of Clipper, we recorded a $21 million gain from the re-measurement to fair value of our previously held equity interest. The financial results of Clipper are included within the “Eliminations and other” category in the segment financial data in Note 18 to the Consolidated Financial Statements.

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 Carrier and Hamilton Sundstrand. 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 Carrier's ongoing portfolio transformation to a higher returns business and an approximately $28 million charge at Hamilton Sundstrand related to the disposition of an aerospace business as part of Hamilton Sundstrand's efforts to implement low cost sourcing initiatives.

In August 2009, we completed the acquisition of the remaining 71% interest in GST Holdings Limited (GST), a fire alarm provider in China, for approximately $250 million bringing our total investment in GST to approximately $360 million. We recorded over $200 million of goodwill and approximately $100 million of identified intangible assets in connection with GST. With the acquisition of the remaining 71% of GST, UTC Fire & Security further strengthened its presence in the Chinese fire safety industry.

In July 2009, Carrier and Watsco, Inc. (Watsco) formed Carrier Enterprise, LLC, a joint venture to distribute Carrier, Bryant, Payne and Totaline residential and light commercial HVAC products in the U.S. sunbelt region and selected territories in the Caribbean and Latin America. As part of the transaction, Carrier contributed its distribution businesses located in these regions into the new venture. In consideration of its contribution, Carrier received approximately 3 million shares of common stock of Watsco and a 40% non-controlling interest in the new venture, which included a business contributed by Watsco. Watsco owns a 60% interest in the venture with options to purchase an additional 20% interest from Carrier in future years. Carrier recognized a gain of approximately $60 million in 2009 as a result of its contribution of the majority of its U.S. residential sales and distribution businesses in this new venture.

The assets and liabilities of acquired businesses are accounted for under the purchase method of accounting and recorded at their fair values at the dates of acquisition. The excess of the purchase price over the estimated fair values of the net assets acquired was recorded as an increase in goodwill of $432 million in 2011, $1.7 billion in 2010, and $630 million in 2009. The results of operations of acquired businesses have been included in the Consolidated Statement of Operations beginning as of the effective date of acquisition.

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

(Dollars in millions)	Balance as of January 1, 2011		Goodwill resulting from business combinations		Foreign currency translation and other		Balance as of December 31, 2011

For 2011, we recorded an additional $244 million of goodwill, reflected within “Eliminations and other” in the above table, related to the finalization of purchase accounting associated with the December 2010 acquisition of Clipper.

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

		2011				2010
(Dollars in millions)		Gross Amount		Accumulated Amortization		Gross Amount		Accumulated Amortization
Amortized:
	Service portfolios	$	2,036	$	(1,060)	$	1,950	$	(942)

	Trademarks and other		762		-		757		-

Total		$	6,590	$	(2,672)	$	6,377	$	(2,317)

Amortization of intangible assets in 2011 and 2010 was $398 million and $387 million, respectively. Amortization of these intangible assets for 2012 through 2016 is expected to approximate $325 million per year.

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 2011, there were no anti-dilutive stock awards excluded from the computation. For 2010 and 2009, the number of stock awards excluded from the computation was 11.4 million and 20.2 million, respectively.

Note 4: Commercial Aerospace Industry Assets and Commitments

Notes to Consolidated Financial Statements [Abstract]

Note 4: Commercial Aerospace Industry Assets and Commitments

We have receivables and other financing assets with commercial aerospace industry customers totaling $3,736 million and $3,384 million at December 31, 2011 and 2010, respectively. Customer financing assets related to commercial aerospace industry customers consist of products under lease of $665 million and notes and leases receivable of $365 million. The notes and leases receivable are scheduled to mature as follows: $37 million in 2012, $57 million in 2013, $26 million in 2014, $30 million in 2015, $30 million in 2016, and $185 million thereafter.

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 units are delivered.

Our commercial aerospace financing and other contractual commitments as of December 31, 2011 were $2,270 million and are exercisable as follows: $131 million in 2012, $252 million in 2013, $427 million in 2014, $206 million in 2015, $368 million in 2016, and $886 million thereafter. 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 $323 million as of December 31, 2011.

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 $235 million and $290 million at December 31, 2011 and 2010, respectively, and are included in Other assets in the accompanying Consolidated Balance Sheets. Deferred revenues generated totaled $1,708 million and $1,474 million at December 31, 2011 and 2010, respectively, and are included in Accrued liabilities and Other long-term liabilities in the accompanying Consolidated Balance Sheet.

As of December 31, 2011, we held a 33% interest in IAE, an international consortium of four shareholders organized to support the V2500 commercial aircraft engine program. Our interest in IAE is accounted for under the equity method of accounting. IAE may offer customer financing in the form of guarantees, secured debt or lease financing in connection with V2500 engine sales. At December 31, 2011, IAE had financing commitments of $728 million and asset value guarantees of $50 million. Our share of IAE's financing commitments and asset value guarantees was approximately $252 million at December 31, 2011. In addition, IAE had lease obligations under long-term non-cancelable leases of approximately $211 million, on an undiscounted basis, through 2020 related to aircraft, which are subleased to customers under long-term leases. These aircraft have fair market values, which approximate the financed amounts, net of reserves. The shareholders of IAE have guaranteed IAE's financing arrangements to the extent of their respective ownership interests. In the event of default by a shareholder on certain of these financing arrangements, the other shareholders would be proportionately responsible.

Reserves related to aerospace receivables and financing assets were $169 million and $133 million at December 31, 2011 and 2010, respectively. Reserves related to financing commitments and guarantees were $73 million and $38 million at December 31, 2011 and 2010, respectively.

Raw materials, work-in-process and finished goods are net of valuation reserves of $884 million and $799 million as of December 31, 2011 and 2010, respectively. As of December 31, 2011 and 2010, inventory also includes capitalized contract development costs of $776 million and $804 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.

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, 2011 and 2010, approximately 75% 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.

(Dollars in millions)	2011		2010
Short-term borrowings:
Commercial paper	$	455	$	-
Other borrowings		175		116
Total short-term borrowings	$	630	$	116

The weighted-average interest rates applicable to short-term borrowings outstanding at December 31, 2011 and 2010 were 1.5% and 6.3%, respectively. The decline in the weighted-average interest rates for short-term borrowings was due to the commercial paper borrowings outstanding at December 31, 2011, which carry favorable interest rates. At December 31, 2011, approximately $1.3 billion was available under short-term lines of credit with local banks at our various domestic and international subsidiaries. In November 2011, our maximum commercial paper borrowing authority was increased from $3 billion to $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.

At December 31, 2011, we had revolving credit agreements with various banks permitting aggregate borrowings of up to $4.0 billion pursuant to a $2.0 billion revolving credit agreement and a $2.0 billion multicurrency revolving credit agreement, both of which expire in November 2016. These revolving credit agreements were signed on November 4, 2011 and replaced our previous revolving credit agreements executed in 2010 which had permitted aggregate borrowings of up to $3.0 billion. As of December 31, 2011, there were no borrowings under either of these revolving credit agreements. The undrawn portions of our revolving credit agreements are also available to serve as backup facilities for the issuance of commercial paper.

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

Our long-term debt consists of the following:

* We may redeem the above notes, in whole or in part, at our option at any time at a redemption price in U.S. Dollars equal to the greater of 100% of the principal amount of the notes to be redeemed or the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted to the redemption date on a semiannual basis at the adjusted treasury rate plus 10-50 basis points. The redemption price will also include interest accrued to the date of redemption on the principal balance of the notes being redeemed.

In December 2011, we redeemed the entire $500 million outstanding principal amount of our 6.100% notes that would otherwise have been due May 15, 2012. In February 2010, we issued two series of fixed rate notes that pay interest semiannually, in arrears, on April 15 and October 15 of each year beginning October 15, 2010. The $1.25 billion principal amount of fixed rate notes bears interest at a rate equal to 4.500% per year and matures on April 15, 2020. The $1.0 billion principal amount of fixed rate notes bears interest at a rate equal to 5.700% per year and matures on April 15, 2040. The proceeds from these notes were used primarily to fund a portion of the acquisition of the GE Security business, and to repay commercial paper borrowings.

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 Carrier. The percentage of total short-term borrowings and long-term debt at variable interest rates was 7% and 2% at December 31, 2011 and 2010, respectively. Interest rates on our commercial paper borrowings are considered variable due to their short-term duration and high-frequency of turnover.

The schedule of principal payments required on long-term debt for the next five years and thereafter is:

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

Notes to Consolidated Financial Statements [Abstract]

Note 10: Income Taxes

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

(Dollars in millions)			2011		2010		2009
Current:
	United States:
		Federal	$	428	$	122	$	239

				331		413		451

Income tax expense			$	2,231	$	1,827	$	1,581

Attributable to items credited (charged) to equity and goodwill			$	864	$	276	$	(782)

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.

The tax effects of net temporary differences and tax carryforwards which gave rise to future income tax benefits and payables at December 31, 2011 and 2010 are as follows:

(Dollars in millions)		2011		2010
Future income tax benefits:
	Insurance and employee benefits	$	2,579	$	1,986
	Other asset basis differences		(569)		(540)
	Other liability basis differences		1,046		958
	Tax loss carryforwards		723		729
	Tax credit carryforwards		1,247		1,371
	Valuation allowances		(977)		(911)

		$	4,049	$	3,593

Future income taxes payable:
	Fixed assets	$	667	$	647
	Other items, net		248		190

		$	915	$	837

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.

It is reasonably possible that over the course of 2012, the amount of valuation allowances may decrease within a range of $150 million to $200 million resulting from potential internal reorganizations that may occur in 2012. These internal reorganizations are separate from the creation of the UTC Climate, Controls & Security and the UTC Propulsion & Aerospace Systems organizations as described above and are a component of our ongoing efforts to improve business efficiency.

The sources of income before income taxes are:

(Dollars in millions)	2011		2010		2009
United States	$	3,293	$	2,655	$	2,584
Foreign		4,312		3,883		3,176

	$	7,605	$	6,538	$	5,760

With few exceptions, U.S. income taxes have not been provided on undistributed earnings of international subsidiaries. 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. Accordingly, we believe that U.S. tax on any earnings that might be repatriated would be substantially offset by U.S. foreign tax credits.

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

	2011	2010	2009
Statutory U.S. federal income tax rate	35.0%	35.0%	35.0%
Tax on international activities	(4.3)%	(7.6)%	(6.9)%
Tax audit settlements	(0.8)%	-	(0.7)%
Other	(0.6)%	0.5%	-

Effective income tax rate	29.3%	27.9%	27.4%

The 2011 effective tax rate increased as compared to 2010 due to the absence of the repatriation of high taxed dividends which had a net favorable impact in 2010. 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 tax rate reflects a non-recurring tax expense reduction associated with management's decision to repatriate additional high tax dividends from the current year to the U.S. in 2010 as a result of U.S. tax legislation enacted at the time. This is 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 our effective tax rate.

The 2009 effective tax rate reflects approximately $38 million of tax expense reductions relating to re-evaluation of our liabilities and contingencies based on global examination activity, including the IRS's completion of 2004 and 2005 examination fieldwork and our related protest filing. As a result of the global examination activity, we recognized approximately $18 million of associated pre-tax interest income adjustments during 2009.

At December 31, 2011, tax credit carryforwards, principally state and federal, and tax loss carryforwards, principally state and foreign, were as follows:

(Dollars in millions)	Tax Credit Carryforwards		Tax Loss Carryforwards
Expiration period:
2012-2016	$	22	$	523
2017-2021		164		125
2022-2031		308		397
Indefinite		753		2,157
Total	$	1,247	$	3,202

At December 31, 2011, we had gross tax-effected unrecognized tax benefits of $946 million, all of which, if recognized, would impact the effective tax rate. 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, 2011, 2010, and 2009 is as follows:

(Dollars in millions)		2011		2010		2009
Balance at January 1	$	891	$	793	$	773
Additions for tax positions related to the current year		71		115		90
Additions for tax positions of prior years		71		80		174
Reductions for tax positions of prior years		(24)		(81)		(20)
Settlements		(63)		(16)		(224)

Balance at December 31	$	946	$	891	$	793


Gross interest expense related to unrecognized tax benefits	$	23	$	27	$	21

Total accrued interest balance at December 31	$	165	$	144	$	142

Included in the balance at December 31, 2009 was $57 million of tax positions whose tax characterization was highly certain but for which there was uncertainty about the timing of tax return inclusion. During 2010, the uncertainty was removed as a result of an accounting method change approved by the Internal Revenue Service (IRS).

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.

Tax years 2004 – 2005 are currently before the Appeals Division of the IRS for resolution discussions regarding certain proposed tax adjustments with which we do not agree. Tax years 2006 – 2008 are currently under review by the Examination Division of the IRS. It is possible that both the 2004 – 2005 appeals activity as well as 2006 – 2008 examination activity may conclude before the end of the second quarter of 2012. The Company expects the IRS to commence their review of the 2009 and 2010 tax years in the first quarter of 2012.

We expect that certain adjustments proposed by the IRS in the course of its examination of tax years 2006 – 2008 and with which we do not agree will further proceed to the Appeals Division of the IRS for resolution discussions. Any discussions with the IRS Appeals Division related to the 2006 – 2008 tax years is likely to continue beyond 2012.

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.

It is reasonably possible that a net reduction within a range of $160 million to $260 million of unrecognized tax benefits may occur over the course of 2012 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 €198 million (approximately $258 million) of tax benefits that we have claimed related to a 1998 German reorganization. These tax benefits are currently being reviewed by the German Tax Office in the course of an audit of tax years 1999 to 2000. In 2008 the German Federal Tax Court denied benefits to another taxpayer in a case involving a German tax law relevant to our reorganization. The determination of the German Federal Tax Court on this other matter was appealed to the European Court of Justice (ECJ) to determine if the underlying German tax law is violative of European Union (EU) principles. On September 17, 2009 the ECJ issued an opinion in this case that is generally favorable to the other taxpayer and referred the case back to the German Federal Tax Court for further consideration of certain related issues. In May 2010, the German Federal Tax Court released its decision, in which it resolved certain tax issues that may be relevant to our audit and remanded the case to a lower court for further development. After consideration of the ECJ decision and the latest German Federal Tax Court decision, we continue to believe that it is more likely than not that the relevant German tax law is violative of EU principles and we have not accrued tax expense for this matter. As we continue to monitor developments related to this matter, it may become necessary for us to accrue tax expense and related interest.

As a result of expected tax examination activity and associated re-evaluation of tax related liabilities and contingencies, it is possible that we may recognize non-cash gains, principally tax, in the range of $225 million to $350 million within the first half of 2012.

- 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 11: Employee Benefit Plans

12 Months Ended

Dec. 31, 2011

Notes to Consolidated Financial Statements [Abstract]

Note 11: 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 $218 million, $200 million and $192 million for 2011, 2010 and 2009, respectively. 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 the company 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, 2011, 33.6 million common shares had been allocated to employees, leaving 18.8 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.

Transition obligation		6		6
Net amount recognized	$	9,290	$	7,045

The amounts included in “Other” in the preceding table reflect the impact of foreign exchange translation, primarily for plans in the U.K. and Canada.

Qualified domestic pension plan benefits comprise approximately 76% 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. 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 $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 in 2011. In 2010, we made $1,001 million of cash contributions and contributed $250 million in UTC common stock to our domestic defined benefit pension plans and made $298 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
	2011	2010	2011	2010	2009
Discount rate	4.7%	5.4%	5.4%	5.9%	6.1%
Salary scale	4.3%	4.4%	4.4%	4.4%	4.4%
Expected return on plan assets	-	-	7.9%	8.0%	8.2%

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 plan's investment management objectives include maintaining an adequate level of diversification, to reduce interest rate and market risk, and to provide 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 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 in 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 consists of a broadly diversified portfolio of corporate bonds, global government bonds and U.S. Treasury STRIPS. These investments are designed to hedge 40% of the interest rate sensitivity of the pension plan liabilities.

Derivatives in the plan are primarily used to manage risk and gain asset class exposure while still maintaining liquidity. Derivative instruments mainly consist of equity futures, interest rate futures, interest rate swaps and currency forward contracts.

Our common stock represents approximately 4% and 3% of total plan assets at December 31, 2011 and 2010, 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.

The fair value measurement of plan assets using significant unobservable inputs (Level 3) changed due to the following:

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 $100 million to our foreign defined benefit pension plans in 2012. Although we are not required to make contributions to our domestic defined benefit pension plans through the end of 2012, we may elect to make discretionary contributions in 2012. 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: $1,356 million in 2012, $1,378 million in 2013, $1,433 million in 2014, $1,493 million in 2015, $1,556 million in 2016, and $8,788 million from 2017 through 2021.

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 84% of the benefit obligation. The postretirement plans are primarily unfunded. Assets in funded plans are primarily invested in cash and cash equivalents.

The estimated amounts that will be amortized from accumulated other comprehensive loss into net periodic benefit cost in 2012 include actuarial net gains of $6 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
	2011	2010	2011	2010	2009

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: $79 million in 2012, $74 million in 2013, $72 million in 2014, $69 million in 2015, $63 million in 2016, and $265 million from 2017 through 2021.

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 2011 and 2010 is for the plan's year-end at June 30, 2010, and June 30, 2009, 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						38		35		37

					$	94	$	90	$	97

For the plan years ended June 30, 2010 and 2009, respectively, we were listed in the National Elevator Industry 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, 2011.

In addition, we participate in several multiemployer arrangements that provide postretirement benefits other than pensions, with the National Elevator Industry 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 $10 million, $10 million and $11 million for 2011, 2010 and 2009, 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. Following initial approval of the LTIP, we may not grant any new awards under previously existing equity compensation plans. As of December 31, 2011, approximately 56 million shares remain available for awards under the LTIP. The LTIP does not contain an 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 shall immediately become vested and exercisable. In addition, under the 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, awards held more than one year remain eligible to vest. 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, 2011, 2010 and 2009, $229 million, $154 million and $153 million, respectively, of compensation cost was recognized in operating results. The associated future income tax benefit recognized was $75 million, $47 million and $49 million for the years ended December 31, 2011, 2010 and 2009, respectively.

For the years ended December 31, 2011, 2010 and 2009, the amount of cash received from the exercise of stock options was $226 million, $386 million and $342 million, respectively, with an associated tax benefit realized of $101 million, $139 million and $95 million, respectively. In addition, for the years ended December 31, 2011, 2010 and 2009, the associated tax benefit realized from the vesting of performance share units was $19 million, $20 million and $33 million, respectively. Also, in accordance with the Compensation – Stock Compensation Topic of the FASB ASC, for the years ended December 31, 2011, 2010 and 2009, $81 million, $94 million and $50 million, respectively, of certain tax benefits have been reported as operating cash outflows with corresponding cash inflows from financing activities.

At December 31, 2011, there was $152 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, 2011 follows:

		Stock Options			Stock Appreciation Rights			Performance Share Units

The weighted-average grant date fair value of stock options and stock appreciation rights granted during 2011, 2010 and 2009 was $20.26, $17.86 and $16.01, respectively. The weighted-average grant date fair value of performance share units, which vest upon achieving certain performance metrics, granted during 2011, 2010, and 2009 was $87.65, $78.73 and $61.56, respectively. The total fair value of awards vested during the years ended December 31, 2011, 2010 and 2009 was $170 million, $172 million and $235 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, 2011, 2010 and 2009 was $336 million, $446 million and $296 million, respectively. The total intrinsic value (which is the stock price at vesting) of performance share units vested was $59 million, $62 million and $100 million during the years ended December 31, 2011, 2010 and 2009, 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, 2011:

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, 2011, 2010 and 2009. Because lattice-based option models incorporate ranges of assumptions for inputs, those ranges are as follows:

	2011	2010	2009
Expected volatility	26% - 32%	24% - 28%	30% - 42%
Weighted-average volatility	26%	25%	30%
Expected term (in years)	7.5 - 8.0	7.4 - 7.9	7.4 - 7.9
Expected dividends	2.4%	2.7%	2.1%
Risk-free rate	0.1% - 3.5%	0.1% - 4.0%	0% - 2.5%

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 12: Restructuring and Other Costs

Note 12: Restructuring Costs

During 2011, we recorded net pre-tax restructuring costs totaling $336 million for new and ongoing restructuring actions. We recorded charges in the segments as follows:

(Dollars in millions)
Otis	$	73
Carrier		46
UTC Fire & Security		80
Pratt & Whitney		67
Hamilton Sundstrand		16
Sikorsky		53
Eliminations and other		1
Total	$	336

The net costs consist of $180 million recorded in cost of sales, $154 million in selling, general and administrative expenses and $2 million in other income, net. As described below, these charges primarily relate to actions initiated during 2011 and 2010.

2011 Actions. During 2011, we initiated restructuring actions relating to ongoing cost reduction efforts, including workforce reductions and consolidation of field operations. We recorded net pre-tax restructuring costs totaling $286 million for restructuring actions initiated in 2011, consisting of $136 million in cost of sales, $147 million in selling, general and administrative expenses and $3 million in other income, net.

We expect the actions that were initiated in 2011 to result in net workforce reductions of approximately 5,000 hourly and salaried employees, the exiting of approximately 2 million net square feet of facilities and the disposal of assets associated with exited facilities. As of December 31, 2011, we have completed, with respect to the actions initiated in 2011, net workforce reductions of approximately 2,200 employees and 50,000 net square feet of facilities have been exited. We are targeting to complete in 2012 the majority of the remaining workforce and all facility related cost reduction actions initiated in 2011. 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 2011 restructuring actions:

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

2010 Actions. During 2011, we recorded net pre-tax restructuring costs totaling $55 million for restructuring actions initiated in 2010, consisting of $36 million in cost of sales and $19 million in selling, general and administrative expenses. The 2010 actions relate to ongoing cost reduction efforts, including workforce reductions and the consolidation of field operations.

As of December 31, 2011, we have completed net workforce reductions of approximately 4,000 employees of an expected 5,000, and have exited 2.5 million net square feet of facilities of an expected 3.9 million net square feet. The remaining workforce and facility reduction actions are targeted for completion during 2012.

The following table summarizes the restructuring accrual balances and utilization by cost type for the 2010 programs:

Note 13: Financial Instruments

12 Months Ended

Dec. 31, 2011

Notes to Consolidated Financial Statements [Abstract]

Note 13: 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 $10.4 billion and $8.5 billion at December 31, 2011 and 2010, respectively.

Additional information pertaining to foreign exchange and hedging activities is included in Note 1 to the Consolidated Financial Statements.

Commodity Forward Contracts. We enter into commodity forward contracts to reduce the risk of fluctuations in the price we pay for certain commodities (for example, nickel) which are used directly in the production of our products, or are components of the products we procure to use in the production of our products. These hedges are economic hedges and the changes in fair value of these contracts are recorded currently in earnings in the period in which they occur. The fair value and outstanding notional amount of contracts hedging commodity exposures were insignificant at December 31, 2011 and 2010, respectively.

The following table summarizes the fair value of derivative instruments as of December 31:

(Dollars in millions)		Balance Sheet Asset Location	2011		2010

Derivatives designated as hedging instruments:
	Foreign Exchange Contracts	Other assets, current	$	69	$	73
	Foreign Exchange Contracts	Other assets		3		24
				72		97

Derivatives not designated as hedging instruments:
	Foreign Exchange Contracts	Other assets, current		40		31
	Foreign Exchange Contracts	Other assets		2		5
				42		36

Total Asset Derivative Contracts			$	114	$	133

		Balance Sheet Liability Location
Derivatives designated as hedging instruments:
	Foreign Exchange Contracts	Accrued liabilities	$	81	$	16
	Foreign Exchange Contracts	Other long-term liabilities		43		1
				124		17

Derivatives not designated as hedging instruments:
	Foreign Exchange Contracts	Accrued liabilities		40		33
	Foreign Exchange Contracts	Other long-term liabilities		1		3
				41		36

Total Liability Derivative Contracts			$	165	$	53

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

	December 31,
(Dollars in millions)	2011		2010
(Loss) gain recorded in Accumulated other comprehensive loss	$	(46)	$	72
Gain reclassified from Accumulated other comprehensive loss into Product sales (effective portion)		96		119

Assuming current market conditions continue, a $31 million pre-tax loss is expected to be reclassified from Accumulated other comprehensive loss into Product sales to reflect the fixed prices obtained from foreign exchange hedging within the next 12 months. At December 31, 2011, all derivative contracts accounted for as cash flow hedges mature by February 2014.

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)		2011		2010
(Loss) gain recognized in Other income, net	$	(39)	$	153

Fair Value Disclosure. The Fair Value Measurements and Disclosure Topic of the FASB ASC defines fair value, establishes a framework for measuring fair value and expands the related disclosure requirements. The Topic indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability, and also defines fair value based upon an exit price model.

During 2011, we recorded other-than-temporary impairment charges of $66 million on an equity investment. The impairment charge recorded on our investment was determined by comparing the carrying value of our investment to the closing market value of the shares on the dates the investment was deemed to be impaired.

During 2010, we had certain non-recurring measurements resulting in impairment charges as well as a gain on the re-measurement to fair value of a previously held equity interest. As previously disclosed, during 2010, we recorded approximately $86 million of asset impairment charges associated with disposition activity within both Carrier and Hamilton Sundstrand and also recorded an other-than-temporary impairment charge of $159 million on our equity investment in Clipper, which had a previous carrying value of approximately $248 million. The impairment charge recorded on our investment in Clipper was determined by comparing the carrying value of our investment to the closing market value of the shares on September 30, 2010. In December 2010, as a result of the acquisition of a controlling interest and all of the remaining shares of Clipper, we recorded a $21 million gain from the re-measurement to fair value of our previously held equity interest. Refer to Note 2 to the Consolidated Financial Statements for further discussion.

Valuation Hierarchy. The Fair Value Measurements and Disclosure Topic of the FASB ASC 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, 2011 and 2010:

(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)
Available-for-sale securities	$	926	$	926	$	-	$	-
Derivative assets		114		-		114		-
Derivative liabilities		(165)		-		(165)		-

(Dollars in millions)	Total Carrying Value at December 31, 2010		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Unobservable inputs (Level 3)
Available-for-sale securities	$	829	$	829	$	-	$	-
Derivative assets		133		-		133		-
Derivative liabilities		(53)		-		(53)		-

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, 2011, there were no significant transfers in and out of Level 1 and Level 2.

As of December 31, 2011, 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, 2011 and 2010:

	2011				2010
(Dollars in millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term receivables	$	283	$	276	$	300	$	276
Customer financing notes receivable		309		297		376		346
Long-term debt (excluding capitalized leases)		(9,575)		(11,639)		(10,117)		(11,500)

The above fair values were computed based on comparable transactions, quoted market prices, discounted future cash flows or an estimate of the amount to be received or paid to terminate or settle the agreement, as applicable. Differences from carrying amounts are attributable to interest and or credit rate changes subsequent to when the transaction occurred. The fair values of Cash and cash equivalents, Accounts receivable, net, Short-term borrowings, and Accounts payable approximate the carrying amounts due to the short-term maturities of these instruments.

We had outstanding commercial aerospace financing and other contractual commitments totaling approximately $2,270 million and $2,032 million at December 31, 2011 and 2010, respectively. Risks associated with changes in interest rates on these commitments are mitigated by the fact that interest rates are variable during the commitment term, and are set at the date of funding based on current market conditions, the fair value of the underlying collateral and the credit worthiness of the customers. As a result, the fair value of these financings is expected to equal the amounts funded. The fair value of the commitment itself is not readily determinable and is not considered significant. Additional information pertaining to these commitments is included in Note 4 to the Consolidated Financial Statements.

Note 14: Credit Quality of Long-Term Receivables

Notes to Consolidated Financial Statements [Abstract]

Note 14: Credit Quality of Long-Term Receivables

In July 2010, the FASB issued ASU No. 2010-20, “Disclosure about the Credit Quality of Financing Receivables and the Allowance for Credit Losses.” This ASU is intended to enhance a financial statement user's ability to evaluate the entity's credit risk exposures and adequacy of its allowance for credit losses by requiring additional disclosure about the nature of credit risk inherent in the portfolio of receivables, factors and methodologies used in estimating the allowance for credit losses and activity that occurs during a period for both financing receivables and allowance for credit losses. The scope of this ASU is limited to financing receivables, as defined by the ASU, and excludes short-term trade accounts receivable and receivables measured at fair value or lower of cost or fair value. We adopted the disclosures under this ASU for the reporting period ended December 31, 2010, with the exception of disclosures about activity that occurs during a reporting period, which became effective for interim and annual periods beginning on or after December 15, 2010. We adopted the interim disclosures required under this ASU during the quarter ended March 31, 2011.

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

Our classes within aerospace long-term receivables are comprised of long-term trade accounts receivable and notes and leases receivable. Long-term trade accounts receivable represent amounts arising from the sale of goods and services with a contractual maturity date of greater than one year and are recognized as “Other assets” in our 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, 2011 and 2010:

(Dollars in millions)	December 31, 2011		December 31, 2010
Long-term trade accounts receivable	$	204	$	198
Notes and leases receivable		365		416
Total long-term receivables	$	569	$	614

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, 2011 and 2010, 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 at December 31, 2011 and 2010 and summarizes the associated reserve for estimated credit losses and exposures at December 31, 2011 and 2010, and the changes in the reserve for the year ended December 31, 2011:

(Dollars in millions)
Beginning balance of the reserve for credit losses and exposure as of January 1, 2011	$	42
Provision		25
Charge-offs		-
Recoveries		(9)
Other		12
Ending balance of the reserve for credit losses and exposure: individually evaluated for impairment as of December 31, 2011	$	70
Ending balance of long-term receivables: individually evaluated for impairment as of December 31, 2011	$	569


Ending balance of the reserve for credit losses and exposure: individually evaluated for impairment as of December 31, 2010	$	42
Ending balance of long-term receivables: individually evaluated for impairment as of December 31, 2010	$	614

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, 2011 and 2010:

		December 31, 2011				December 31, 2010
(Dollars in millions)		Long-term trade accounts receivable		Notes and leases receivable		Long-term trade accounts receivable		Notes and leases receivable

Commercial customer financing arrangements		-		-		191		1

______________

* Represents IAE's gross obligation; at December 31, 2011 and 2010 our proportionate share of IAE's obligations was 33%.

We also have obligations arising from sales of certain businesses and assets, including 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 $138 million and $139 million at December 31, 2011 and 2010, respectively. For additional information regarding the environmental indemnifications, see Note 17 to the Consolidated Financial Statements.

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 Guarantees Topic 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, 2011 and 2010 are as follows:

(Dollars in millions)	2011		2010
Balance as of January 1	$	1,136	$	1,072
Warranties and performance guarantees issued		475		440
Settlements made		(440)		(379)
Other		297		3
Balance as of December 31	$	1,468	$	1,136

For 2011, the increase reflected within “Other” in the above table primarily related to the finalization of purchase accounting associated with the December 2010 acquisition of Clipper

Note 16: 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 collaborative partners for their share of sales are recorded as an expense in our financial statements based upon the terms and nature of the arrangement. Costs associated with engine programs under collaborative arrangements are expensed as incurred. Under these arrangements, collaborators contribute their program share of engine parts, incur their own production costs and make certain payments to Pratt & Whitney for shared or joint program costs. The reimbursement of the collaborators' share of program costs is recorded as a reduction of the related expense item at that time. As of December 31, 2011, the collaborators' interests in all commercial engine programs ranged from 12% to 48%, inclusive of a portion of Pratt & Whitney's interests held by other participants. Pratt & Whitney is the principal participant in all existing collaborative arrangements. There are no individually significant collaborative arrangements and none of the partners exceed a 31% share in an individual program.

In September 2011, Pratt & Whitney announced a new collaboration with JAEC and MTU to provide the PurePower PW1100G-JM engine for the Airbus A320neo program. Under the collaboration agreement, MTU will hold an 18% share and be responsible for the engine's low pressure turbine and participate jointly with Pratt & Whitney to provide the high pressure compressor for the engine. JAEC will hold a 23% share and be responsible for the engine fan, low pressure compressor and combustor/diffuser. Pratt & Whitney will hold the remaining shares and will be responsible for the remainder of the PurePower PW1100G-JM engine and systems integration.

On October 12, 2011, Pratt & Whitney and Rolls-Royce announced an agreement to restructure their interests in IAE and to form a new joint venture to develop engines to power the next generation of 120 to 230 passenger mid-size aircraft that will replace the existing fleet of mid-size aircraft currently in service or in development. Consummation of each of these transactions is subject to regulatory approvals and other closing conditions. We expect the restructuring of the parties' interests in IAE to be completed in mid-2012. The closing of the new joint venture is also subject to the completion of the restructuring of the parties' interests in IAE and may take a substantially longer period of time to complete. See Note 2 to the Consolidated Financial Statements for further discussion.

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)		2011		2010		2009
Collaborator share of sales:
	Cost of products sold	$	963	$	850	$	772
	Cost of services sold		36		38		29

Collaborator share of program costs (reimbursement of expenses incurred):
	Cost of products sold		(88)		(83)		(66)
	Research and development		(220)		(135)		(97)
	Selling, general and administrative		(4)		(5)		(4)

Note 17: Contingent Liabilities

Notes to Consolidated Financial Statements [Abstract]

Note 17: Contingent Liabilities

Leases. We occupy space and use certain equipment under lease arrangements. Rental commitments of $1,883 million at December 31, 2011 under long-term non-cancelable operating leases are payable as follows: $515 million in 2012, $404 million in 2013, $292 million in 2014, $184 million in 2015, $115 million in 2016 and $373 million thereafter. Rent expense was $453 million in 2011, $445 million in 2010 and $463 million in 2009.

Additional information pertaining to commercial aerospace rental commitments is included in Note 4 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, 2011, we had $617 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 the 1983 offer. In the absence of actual damages, the trial court judge awarded the DOJ the maximum civil penalty of $7.09 million, or $10,000 for each of the 709 invoices Pratt & Whitney submitted in 1989 and later under the contracts. In September 2008, both the DOJ and UTC appealed the decision to the Sixth Circuit Court of Appeals. In November 2010, the Sixth Circuit affirmed Pratt & Whitney's liability under the False Claims Act and remanded the case to the U.S. District Court for further proceedings on the question of damages. Should the government ultimately prevail, the outcome of this matter could result in a material effect on our results of operations in the period in which a liability would be recognized or cash flows for the period in which damages would be paid.

As previously disclosed, in December 2008, the U.S. Department of Defense (DOD) issued a contract claim against Sikorsky to recover overpayments the DOD alleges it has incurred since January 2003 in connection with cost accounting changes approved by the DOD and implemented by Sikorsky in 1999 and 2006. These changes relate to the calculation of material overhead rates in government contracts. The DOD claims that Sikorsky's liability is approximately $92 million (including interest through December 2011). We believe this claim is without merit and Sikorsky filed an appeal in December 2009 with the U.S. Court of Federal Claims, which is pending. We do not believe the resolution of this matter will have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

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

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

We continue to evaluate the range of possible outcomes of these separate but related export compliance matters, and have recognized a potential liability at December 31, 2011 of $45 million. We are currently unable to predict the precise timing or outcome of the discussions. We do not believe the ultimate resolution of these matters, individually or collectively, will have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

Other. 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 15 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.

Notes to Consolidated Financial Statements [Abstract]

Note 18: Segment Financial Data

Our operations for the periods presented herein are classified into six principal segments. The segments are generally determined based on the management of the businesses and on the basis of separate groups of operating companies, each with general operating autonomy over diversified products and services.

Otis products include elevators, escalators, moving walkways and service sold to customers in the commercial and residential property industries around the world.

Carrier products include HVAC and refrigeration systems, controls, services and energy efficient products for residential, commercial, industrial and transportation applications.

UTC Fire & Security products include fire and special hazard and suppression systems and firefighting equipment, security, monitoring and rapid response systems and service and security personnel for a diversified international customer base principally in the industrial, commercial and residential property sectors.

Pratt & Whitney products include commercial, military, business jet and general aviation aircraft engines, parts and services, industrial gas turbines, geothermal power systems and space propulsion sold to a diversified customer base, including international and domestic commercial airlines and aircraft leasing companies, aircraft manufacturers, and U.S. and foreign governments. Pratt & Whitney also provides product support and a full range of overhaul, repair and fleet management services and produces land-based power generation equipment.

Hamilton Sundstrand provides aerospace and industrial products and aftermarket services for diversified industries worldwide. Aerospace products include power generation, management and distribution systems, flight systems, engine control systems, environmental control systems, fire protection and detection systems, auxiliary power units and propeller systems. Industrial products include air compressors, metering pumps and heavy duty process pumps.

Sikorsky products include military and commercial helicopters, aftermarket helicopter and aircraft parts and services.

On September 28, 2011, we announced a new organizational structure to better serve customers and drive growth and achieve greater efficiencies through greater integration across certain product lines. This new structure combines Carrier and UTC Fire & Security into a new segment called UTC Climate, Controls & Security. Beginning with the first quarter of 2012, Carrier and UTC Fire & Security will report combined financial and operational results as part of this new segment. As part of this new organizational structure, we also created UTC Propulsion & Aerospace Systems, a new organization consisting of Pratt & Whitney and Hamilton Sundstrand. Pratt & Whitney and Hamilton Sundstrand will continue to report their financial and operational results as separate segments, which is consistent with how we will allocate resources and measure the financial performance of these businesses. We have reported our financial and operational results for the periods presented herein under the six principal segments noted above, consistent with how we have reviewed our business operations for decision-making purposes, resource allocation and performance assessment during 2011.

Segment Information. Total sales by segment include intersegment sales, which are generally made at prices approximating those that the selling entity is able to obtain on external sales. Segment information for the years ended December 31 is as follows:

Note 1: Summary of Accounting Principles (Policy)	12 Months Ended
Note 1: Summary of Accounting Principles (Policy)	Dec. 31, 2011
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, 2011 and 2010, the amount of such restricted cash was approximately $37 million and $75 million, respectively. At both December 31, 2011 and 2010, all restricted cash is included in current assets.
Receivables Policy [Text Block]	Accounts Receivable. Current and long-term accounts receivable include retainage of $154 million and $165 million and unbilled receivables of $1,060 million and $862 million as of December 31, 2011 and 2010, 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 Carrier 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 $144 million and $137 million at December 31, 2011 and 2010, 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 Intangibles – Goodwill and Other Topic of the FASB ASC. This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. We early adopted the FASB ASU No. 2011-08, “Testing Goodwill for Impairment,” in connection with the performance of our annual goodwill impairment test. Under ASU 2011-08, entities are provided with the option of first performing a qualitative assessment on none, some, or all of its reporting units to determine whether further quantitative impairment testing is necessary. An entity may also bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative impairment test. During 2011, 2010, and 2009, we were not required to record any significant impairments to the carrying value of goodwill or indefinite-lived intangible assets. Intangible assets consist of service portfolios, patents and trademarks, customer relationships and other intangible assets. 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. Estimated useful lives of service portfolios generally range from 5 to 30 years. Estimated useful lives of patents and finite-lived trademarks generally range from 3 to 40 years. Estimated useful lives of customer relationships and other assets generally range from 2 to 32 years. These intangible assets are amortized based on the pattern in which the economic benefits of the intangible assets are consumed. If a pattern of economic benefit cannot be reliably determined, a straight-line amortization method is used. 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 units are delivered.
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, 2011 and 2010, we had certain non-recurring measurements resulting in impairment charges of $66 million and $245 million, respectively. See Note 13 to the Consolidated Financial Statements for additional information.
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 business, 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.
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 collaborative partners 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 Development And Computer Software 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. 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.
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 13 to the Consolidated Financial Statements.
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, 2011 and 2010, the outstanding liability for asset retirement obligations was $164 million and $189 million, respectively.
Pension And Other Postretirement Plans Pensions Policy	Pension and Postretirement Obligations. Guidance under the Compensation – Retirement Benefits Topic of the FASB ASC 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.

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.

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

Department of Justice Lawsuit Against Pratt and Whitney [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	1999
Loss Contingency Allegations	As previously disclosed, the 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 Damages Sought	$624 million
Loss Contingency Actions Taken By Plaintiff And Defendant	On August 1, 2008, the trial court judge held that the Air Force had not suffered any actual damages because Pratt & Whitney had made significant price concessions. However, the trial court judge found that Pratt & Whitney violated the False Claims Act due to inaccurate statements contained in the 1983 offer. In the absence of actual damages, the trial court judge awarded the DOJ the maximum civil penalty of $7.09 million, or $10,000 for each of the 709 invoices Pratt & Whitney submitted in 1989 and later under the contracts. In September 2008, both the DOJ and UTC appealed the decision to the Sixth Circuit Court of Appeals. In November 2010, the Sixth Circuit affirmed Pratt & Whitney’s liability under the False Claims Act and remanded the case to the U.S. District Court for further proceedings on the question of damages.
Loss Contingency Actions Taken By Defendant	In September 2008, both the DOJ and UTC appealed the decision to the Sixth Circuit Court of Appeals.
Department of Defense Contract Claim Against Sikorsky [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	December 2008
Loss Contingency Allegations	As previously disclosed, in December 2008, the U.S. Department of Defense (DOD) issued a contract claim against Sikorsky to recover overpayments the DOD alleges it has incurred since January 2003 in connection with cost accounting changes approved by the DOD and implemented by Sikorsky in 1999 and 2006. These changes relate to the calculation of material overhead rates in government contracts. The DOD claims that Sikorsky’s liability is approximately $92 million (including interest through December 2011).
Loss Contingency Damages Sought	$92 million (including interest through December 2011)
Loss Contingency Actions Taken By Defendant	We believe this claim is without merit and Sikorsky filed an appeal in December 2009 with the U.S. Court of Federal Claims, which is pending.
