Summary of Accounting Principles

SUMMARY OF ACCOUNTING PRINCIPLES

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from those estimates. Certain reclassifications have been made to the prior year amounts to conform to the current year presentation.

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, 2014 and 2013, the amount of such restricted cash was approximately $255 million and $47 million, respectively.

Accounts Receivable. Current and long-term accounts receivable as of December 31, 2014 include retainage of $147 million and unbilled receivables of $2,624 million, which includes approximately $823 million of unbilled receivables under commercial aerospace long-term aftermarket contracts. Current and long-term accounts receivable as of December 31, 2013 include retainage of $173 million and unbilled receivables of $2,172 million, which includes approximately $677 million of unbilled receivables under commercial aerospace long-term aftermarket contracts. See Note 5 for discussion of commercial aerospace industry assets and commitments.

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.

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

Inventories and Contracts in Progress. Inventories and contracts in progress are stated at the lower of cost or estimated realizable value and are primarily based on first-in, first-out (FIFO) or average cost methods; however, certain UTC Aerospace Systems and UTC Climate, Controls & Security entities use the last-in, first-out (LIFO) method. If inventories that were valued using the LIFO method had been valued under the FIFO method, they would have been higher by $130 million and $133 million at December 31, 2014 and 2013, respectively.

Costs accumulated against specific contracts or orders are at actual cost. Valuation reserves for excess, obsolete, and slow-moving inventory are estimated by comparing the inventory levels of individual parts to both future sales forecasts or production requirements and historical usage rates in order to identify inventory where the resale value or replacement value is less than inventoriable cost. Other factors that management considers in determining the adequacy of these reserves include whether individual inventory parts meet current specifications and cannot be substituted for a part currently being sold or used as a service part, overall market conditions, and other inventory management initiatives. Manufacturing costs are allocated to current production and firm contracts.

Equity Method Investments. Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in Other assets on the Consolidated Balance Sheet. Under this method of accounting, our share of the net earnings or losses of the investee is included in Other income, net on the Consolidated Statement of Operations since the activities of the investee are closely aligned with the operations of the business segment holding the investment. We evaluate our equity method investments whenever events or changes in circumstance indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period.

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.

Intangible assets consist of service portfolios, patents, trademarks/tradenames, customer relationships and other intangible assets including a collaboration asset established in connection with the restructuring of participants' interests in IAE as discussed further in Note 2. Acquired intangible assets are recognized at fair value in purchase accounting and then amortized to cost of sales and selling, general & administrative expenses over the applicable useful lives. Also included within other intangible assets are commercial aerospace payments made to secure certain contractual rights to provide product on new aircraft platforms. Consideration paid on these contractual commitments is capitalized when it is no longer conditional.

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



Collaboration asset	30 years
Customer relationships and related programs	2 to 32 years
Purchased service contracts	5 to 31 years
Patents & trademarks	3 to 40 years
Exclusivity assets	3 to 25 years

Other Long-Lived Assets. We evaluate the potential impairment of other long-lived assets when appropriate. If the carrying value of other long-lived assets held and used exceeds the sum of the undiscounted expected future cash flows, the carrying value is written down to fair value.

Long-Term Financing Receivables. Our long-term 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 of those other receivables are not significant.

Long-term trade accounts receivable represent amounts arising from the sale of goods and services with a contractual maturity date of greater than one year and are recognized as "Other assets" in our Consolidated Balance Sheet. Notes and leases receivable represent notes and lease receivables other than receivables related to operating leases, and are recognized as "Customer financing assets" in our Consolidated Balance Sheet. The following table summarizes the balance by class of aerospace long-term receivables as of December 31, 2014 and 2013:



(dollars in millions)	2014		2013
Long-term trade accounts receivable	$	838	$	714
Notes and leases receivable	424		583
Total long-term receivables	$	1,262	$	1,297

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.

We determine credit ratings for each customer in our 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. Customer credit ratings range from an extremely strong capacity to meet financial obligations, to customers whose uncollateralized receivable is in default. 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. Based upon the customer credit ratings, approximately 8% and 9% of the total long-term receivables reflected in the table above were considered to bear high credit risk as of December 31, 2014 and 2013, respectively. See Note 5 for further discussion of commercial aerospace industry assets and commitments.

Reserves for credit losses on receivables relate 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. Our long-term receivables reflected in the table above, which include reserves of $10 million and $49 million as of December 31, 2014 and 2013, respectively, are individually evaluated for impairment. At both December 31, 2014 and 2013, we did 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.

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. As a result of our diverse product and service mix and customer base, we use multiple revenue recognition practices. We recognize sales for products and services in accordance with the provisions of Staff Accounting Bulletin (SAB) Topic 13, Revenue Recognition, as applicable. Products and services included within the scope of this SAB Topic include heating, ventilating, air-conditioning and refrigeration systems, non-complex alarm and fire detection and suppression systems, commercially funded research and development contracts and non-complex aerospace components. Sales within the scope of this SAB Topic are recognized when persuasive evidence of an arrangement exists, product delivery has occurred or services have been rendered, pricing is fixed or determinable and collectability is reasonably assured. Subsequent changes in service contracts are accounted for prospectively.

Contract Accounting and Separately Priced Maintenance and Extended Warranty Aftermarket Contracts: For our construction-type and certain production-type contracts, sales are recognized on a percentage-of-completion basis following contract accounting methods. Contracts consist of enforceable agreements which form the basis of our unit of accounting for measuring sales, accumulating costs and recording loss provisions as necessary. Contract accounting requires estimates of award fees and other sources of variable consideration as well as future costs over the performance period of the contract. Cost estimates also include the estimated cost of satisfying our offset obligations required under certain contracts. Cost 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 production-type helicopter contracts is measured using units of delivery or other contractual milestones. The extent of progress towards completion on our development and other cost reimbursement contracts in our aerospace businesses and elevator and escalator sales, installation, modernization and other construction contracts in our commercial businesses is measured using cost-to-cost based input measures. Contract costs include estimated inventoriable manufacturing, engineering, product warranty and product performance guarantee costs, as appropriate.

For separately priced product maintenance and extended warranty aftermarket contracts, sales are recognized over the contract period. In the commercial businesses, sales are primarily recognized on a straight-line basis. In the aerospace businesses, sales are primarily recognized in proportion to cost as sufficient historical evidence indicates that costs of performing services under the contract are incurred on an other than straight-line basis.

Loss provisions on original equipment contracts are recognized to the extent estimated contract costs exceed the estimated consideration 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 which obligates us to perform. For existing commitments, anticipated losses on contracts are recognized in the period in which losses become evident. Products contemplated under contractual arrangements include firm quantities of products sold under contract and, in the large commercial engine and wheels and brakes businesses, future highly probable sales of replacement parts required by regulation that are expected to be sold subsequently for incorporation into the original equipment. In the large commercial engine and wheels and brakes businesses, when the combined original equipment and aftermarket arrangements for each individual sales campaign are profitable, we record original equipment product losses, as applicable, at the time of delivery.

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. Operating profits included significant net unfavorable changes in aerospace contract estimates of approximately $240 million in 2014 driven by the $438 million unfavorable impact of a revision in estimate on the CH-148 Canadian Maritime Helicopter program, partially offset by several net favorable contract adjustments recorded throughout the year, largely at the Pratt & Whitney segment. See Note 6 for further discussion of the CH-148 Canadian Maritime Helicopter program.

Collaborations: Sales generated from engine programs, spare parts sales, and aftermarket business under collaboration arrangements are recorded consistent with our revenue recognition policies in our consolidated financial statements. Amounts attributable to our collaborators for their share of sales are recorded as an expense in our financial statements based upon the terms and nature of the arrangement. Costs associated with engine programs under collaborative arrangements are expensed as incurred. Under these arrangements, collaborators contribute their program share of engine parts, incur their own production costs and make certain payments to Pratt & Whitney for shared or joint program costs. The reimbursement of a collaborator's share of program costs is recorded as a reduction of the related expense item at that time.

Cash Payments to Customers: UTC Climate, Controls & Security customarily offers its customers incentives to purchase products to ensure an adequate supply of its products in the distribution channels. The principal incentive program provides reimbursements to distributors for offering promotional pricing for our products. We account for incentive payments made as a reduction in sales. In our aerospace businesses, we may make participation payments to certain customers to secure certain contract rights. We classify the subsequent amortization of these acquired intangible assets from our customers as a reduction in sales. Contractually stated prices in arrangements with our customers that include the acquisition of intangible rights within the scope of the Intangibles - Goodwill and Other Topic of the FASB ASC and deliverables within the scope of the Revenue Recognition Topic of the FASB ASC are not presumed to be representative of fair value for determining the amounts to allocate to each element of an arrangement.

Research and Development. Research and development costs not specifically covered by contracts and those related to the company sponsored share of research and development activity in connection with cost-sharing arrangements are charged to expense as incurred. Government research and development support, not associated with specific contracts, is recorded as a reduction to research and development expense in the period earned. Repayment, if any, is in the form of future royalties and is conditioned upon the achievement of certain financial targets including specific aircraft engine sales, total aircraft engine sales volume and total year-over-year sales growth of the entity receiving the government funding. Given the conditional and uncertain nature of any repayment obligations, royalty expense is typically recorded only upon engine shipment or is otherwise accrued monthly based upon the forecasted impact for the current year. The cumulative funding received under existing relationships has been approximately $2.2 billion of which approximately $600 million has been repaid to date in the form of royalties.

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

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

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 as a component of product sales or expenses, as applicable, when the hedged 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. Additional information pertaining to foreign currency forward contracts is included in Note 14.

Environmental. Environmental investigatory, remediation, operating and maintenance costs are accrued when it is probable that a liability has been incurred and the amount can be reasonably estimated. The most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site, including existing technology, current laws and regulations and prior remediation experience. Where no amount within a range of estimates is more likely, the minimum is accrued. For sites with multiple responsible parties, we consider our likely proportionate share of the anticipated remediation costs and the ability of the other parties to fulfill their obligations in establishing a provision for those costs. Liabilities with fixed or reliably determinable future cash payments are discounted. Accrued environmental liabilities are not reduced by potential insurance reimbursements.

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.

Product Performance Obligations. We extend performance and operating cost guarantees beyond our normal service and warranty policies for extended periods on some of our products, particularly commercial aircraft engines. Liability under such guarantees is based upon future product performance and durability. We accrue for such costs that are probable and can be reasonably estimated. In addition, we incur discretionary costs to service our products in connection with product performance issues. The costs associated with these product performance and operating cost guarantees require estimates over the full terms of the agreements, and require management to consider factors such as the extent of future maintenance requirements and the future cost of material and labor to perform the services. These cost estimates are largely based upon historical experience. See Note 16 for further discussion.

Collaborative Arrangements. In view of the risks and costs associated with developing new engines, Pratt & Whitney has entered into certain collaboration arrangements in which sales, costs and risks are shared. Sales generated from engine programs, spare parts, and aftermarket business under collaboration arrangements are recorded as earned in our financial statements. Amounts attributable to our collaborators for their share of sales are recorded as an expense in our financial statements based upon the terms and nature of the arrangement. Costs associated with engine programs under collaborative arrangements are expensed as incurred. Under these arrangements, collaborators contribute their program share of engine parts, incur their own production costs and make certain payments to Pratt & Whitney for shared or joint program costs. The reimbursement of the collaborators' share of program costs is recorded as a reduction of the related expense item at that time. As of December 31, 2014, the collaborators' interests in all commercial engine programs ranged from 14% to 49%, inclusive of a portion of Pratt & Whitney's interests held by other participants. Pratt & Whitney is the principal participant in all existing collaborative arrangements. There are no individually significant collaborative arrangements and none of the collaborators exceed a 31% share in an individual program. 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)	2014			2013			2012
Collaborator share of sales:
Cost of products sold	$	1,778		$	1,820		$	1,295

Business Combination, Recognized Identifiable Assets Acquired, Goodwill, and Liabilities Assumed, Net [Abstract]

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

BUSINESS ACQUISITIONS, DISPOSITIONS, GOODWILL AND INTANGIBLE ASSETS

Business Acquisitions and Dispositions. Our investments in businesses in 2014, 2013 and 2012 totaled $530 million (including debt assumed of $128 million), $151 million and $18.6 billion (including debt assumed of $2.6 billion), respectively. Our investments in businesses in 2014 consisted of the acquisition of the majority interest in a Pratt & Whitney joint venture and a number of small acquisitions, primarily in our commercial businesses.

In 2013, we completed the sale of the Pratt & Whitney Power Systems business to Mitsubishi Heavy Industries (MHI) for $432 million, excluding contingent consideration valued at approximately $200 million, and we entered into a long-term engineering and manufacturing agreement with MHI, generating a pre-tax gain of approximately $193 million ($132 million after tax). We also completed the acquisition of Grupo Ascensores Enor, S.A. (Enor), a privately held company headquartered in Spain with operations in Spain and Portugal, which designs, manufactures, installs and services elevators. Under the terms of the transaction, Zardoya Otis, S.A. (ZOSA), a non-wholly owned subsidiary of the Company, exchanged publicly traded shares of ZOSA with a fair value of approximately $240 million as of the transaction completion date for all of the shares of Enor.

In 2012, we issued approximately $10.9 billion of long-term debt and equity units and completed the acquisition of Goodrich, for a total enterprise value of $18.3 billion, including $1.9 billion in net debt assumed. The acquired Goodrich businesses were combined with the legacy Hamilton Sundstrand businesses to form the UTC Aerospace Systems segment. In connection with the Goodrich acquisition, we recorded approximately $11.6 billion of goodwill and $10.1 billion of identifiable intangible assets, including approximately $8.6 billion of customer relationship and related program assets. We recorded assumed liabilities of approximately $2.2 billion related to customer contractual obligations on certain OEM development programs where the expected costs exceeded the expected revenue under contract. These liabilities are being liquidated in accordance with the underlying economic pattern of obligations, as reflected by the net cash outflows incurred on the OEM contracts. Total consumption of the contractual obligations was approximately $249 million and $278 million in 2014 and 2013, respectively. Expected consumption of the contractual obligations is as follows: $229 million in 2015, $240 million in 2016, $259 million in 2017, $209 million in 2018, $192 million in 2019 and $480 million thereafter.

In connection with regulatory approval of the Goodrich acquisition, regulatory authorities required UTC to dispose of the Goodrich electric power systems and the Goodrich pumps and engine controls businesses. We completed the sales of these businesses in 2013.

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

On June 29, 2012, Pratt & Whitney, Rolls-Royce plc (Rolls-Royce), MTU Aero Engines AG (MTU), and Japanese Aero Engines Corporation (JAEC), participants in the IAE International Aero Engines AG (IAE) collaboration, completed a restructuring of their interests in IAE. As a result of the this transaction, Pratt & Whitney holds a 61% net interest in the collaboration and a 49.5% ownership interest in IAE. IAE's business purpose is to coordinate the design, development, manufacturing and product support of the V2500 program through involvement with the collaborators. IAE retains limited equity with the primary economics of the V2500 program passed to the participants in the separate collaboration arrangement. As such, we have determined that IAE is a variable interest entity with Pratt & Whitney its primary beneficiary, and IAE has, therefore, been consolidated. The carrying amounts and classification of assets and liabilities for IAE in our Consolidated Balance Sheet as of December 31, 2014 and 2013 are as follows:



(dollars in millions)	2014		2013
Current assets	$	1,820	$	1,616
Noncurrent assets	756		1,066
Total assets	$	2,576	$	2,682
Current liabilities	$	1,795	$	1,895
Noncurrent liabilities	1,227		1,085
Total liabilities	$	3,022	$	2,980

UTC Climate, Controls & Security continued its portfolio transformation efforts in 2014 with the disposition of a number of businesses, resulting in a net gain of approximately $30 million, primarily due to a gain on the sale of an interest in a joint venture in North America. UTC Climate, Controls & Security's portfolio transformation in 2013 included the disposition of a number of businesses, resulting in a net gain of approximately $55 million, including gains from the sale of businesses in Hong Kong and Australia, and in 2012 included the disposition of a number of businesses resulting in impairment and other charges totaling approximately $180 million. During 2012, UTC Climate, Controls & Security also sold a controlling interest in a manufacturing and distribution joint venture in Asia generating a gain of approximately $215 million, and a controlling interest in a Canadian distribution business generating a gain of approximately $120 million.

Goodwill. The changes in the carrying amount of goodwill, by segment, in 2014 are as follows:



(dollars in millions)	Balance as of January 1, 2014		Goodwill resulting from business combinations		Foreign currency translation and other			Balance as of December 31, 2014
Otis	$	1,741	$	35	$	(112	)	$	1,664
UTC Climate, Controls & Security	9,727		13		(332		)	9,408

Total	$	28,168	$	256	$	(628	)	$	27,796

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



	2014					2013
(dollars in millions)	Gross Amount		Accumulated Amortization			Gross Amount		Accumulated Amortization
Amortized:
Service portfolios	$	2,103	$	(1,309	)	$	2,234	$	(1,295	)

Total	$	19,702	$	(4,142	)	$	19,196	$	(3,675	)

Customer relationship intangible assets include payments made to our customers to secure certain contractual rights. We amortize these intangible assets based on the underlying pattern of economic benefit, which may result in an amortization method other than straight-line. We classify amortization of such payments as a reduction of sales. Amortization of intangible assets was $718 million, $710 million and $547 million in 2014, 2013 and 2012, respectively. The IAE collaboration intangible asset is amortized based upon the economic pattern of benefits as represented by the underlying cash flows. Prior to 2014, these cash flows were negative, and, accordingly, no amortization had previously been recorded. The following is the expected amortization of intangible assets for 2015 through 2019, which reflects an increase in expected amortization expense due to the pattern of economic benefit on certain aerospace intangible assets increasing over time:



(dollars in millions)	2015		2016		2017		2018		2019
Amortization expense	$	707	$	715	$	764	$	828	$	806

Discontinued Operations

DISCONTINUED OPERATIONS

In 2012, the UTC Board of Directors approved plans for the divestiture of a number of non-core businesses, which were completed with the sale of Pratt & Whitney Rocketdyne (Rocketdyne) on June 14, 2013. Cash generated from these divestitures was used to repay debt incurred to finance the Goodrich acquisition in 2012. On February 12, 2013, we completed the disposition of UTC Power to ClearEdge Power, and have no continuing involvement with the UTC Power business post-disposition.

On December 13, 2012, we completed the sale of the legacy Hamilton Sundstrand Industrial businesses. On August 7, 2012, we completed the disposition of Clipper Windpower (Clipper) and have no continuing involvement with the Clipper business following disposition.

The legacy Hamilton Sundstrand Industrial businesses, as well as Clipper, Rocketdyne and UTC Power all met the "held-for-sale" criteria in 2012. The results of operations, including the net realized gains and losses on disposition, and the related cash flows which resulted from these non-core businesses, have been reclassified to Discontinued Operations in our Consolidated Statements of Operations and Cash Flows.

The following summarized financial information for our discontinued operations businesses has been segregated from continuing operations and reported as Discontinued Operations in 2013. There was no discontinued operations activity in 2014.



(dollars in millions)	2013
Discontinued Operations:
Net sales	$	309
Income from operations	$	63
Income tax expense	(32		)
Income from operations, net of income taxes	31
Loss on disposal	(33		)

These outstanding stock awards are not included in the computation of diluted earnings per share because the effect would have been anti-dilutive. For 2014 and 2012, there were 3.5 million and 4.7 million anti-dilutive stock awards excluded from the computation, respectively. For 2013, there were no anti-dilutive stock awards excluded from the computation.

Commercial Aerospace Industry Assets and Commitments

NOTE 5: COMMERCIAL AEROSPACE INDUSTRY ASSETS AND COMMITMENTS

We have receivables and other financing assets with commercial aerospace industry customers totaling $5,573 million and $6,193 million at December 31, 2014 and 2013, respectively. These include customer financing assets related to commercial aerospace industry customers, consisting of products under lease of $583 million and $662 million, and notes and leases receivable of $424 million and $586 million, at December 31, 2014 and 2013, respectively.

Aircraft financing commitments, in the form of 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 consistent with market terms and conditions. We may also lease aircraft and subsequently sublease the aircraft to customers under long-term non-cancelable operating leases. 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, which are included in "Other commercial aerospace commitments" in the table below. Payments made on these contractual commitments are included in intangible assets and are amortized over the term of underlying economic benefit. Our commercial aerospace financing and other contractual commitments as of December 31, 2014 were approximately $11.3 billion. We have entered into certain collaboration arrangements, which may include participation by our collaboration partners in these commitments.

The following is the expected maturity of commercial aerospace industry assets and commitments as of December 31, 2014:



(dollars in millions)	Committed			2015			2016			2017			2018			2019			Thereafter
Notes and leases receivable	$	424		$	43		$	103		$	42		$	26		$	25		$	185
Commercial aerospace financing commitments	$	3,152		$	574		$	489		$	363		$	449		$	375		$	902

Total commercial commitments	$	8,477		$	967		$	966		$	928		$	968		$	853		$	3,795

In exchange for the increased ownership and collaboration interests and intellectual property license, Pratt & Whitney paid Rolls-Royce $1.5 billion at closing with additional payments due to Rolls-Royce contingent upon each hour flown by the V2500-powered aircraft in service as of June 29, 2012 during the fifteen-year period following closing of the purchase. These payments are being capitalized as a collaboration intangible asset and amortized based upon the economic pattern of benefits of the V2500 program as represented by the underlying cash flows. Prior to 2014, these cash flows were negative, and, accordingly, no amortization had previously been recorded. The flight hour payments are included in Other commercial aerospace commitments in the table above.

Our financing commitments 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 $632 million as of December 31, 2014.

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 unbilled receivables and deferred revenues. Unbilled receivables under these long-term aftermarket contracts totaled $823 million and $677 million at December 31, 2014 and 2013, respectively, and are included in Accounts receivable and Other assets in the accompanying Consolidated Balance Sheet. Deferred revenues totaled $3,553 million and $3,230 million at December 31, 2014 and 2013, respectively, and are included in Accrued liabilities and Other long-term liabilities in the accompanying Consolidated Balance Sheet.

Reserves related to aerospace receivables and financing assets were $243 million at both December 31, 2014 and 2013, respectively. Reserves related to financing commitments and guarantees were $67 million and $76 million at December 31, 2014 and 2013, respectively.

Raw materials, work-in-process and finished goods are net of valuation reserves of $863 million and $1,025 million as of December 31, 2014 and 2013, respectively. 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.

During the quarter ended June 30, 2014, Sikorsky and the Canadian Government signed amendments to their existing contracts for development, production and support of the CH-148 helicopter. These amendments included significant changes in program scope, governance and delivery methodology. Accordingly, in the second quarter of 2014 we recognized a change in estimate on this program resulting in the liquidation of approximately $1.3 billion of inventory, including all capitalized contract development costs related to this program. As of December 31, 2013, inventory included approximately $740 million of capitalized contract development costs related to this program.

Inventory also includes capitalized contract development costs related to certain aerospace programs at UTC Aerospace Systems. As of December 31, 2014 and 2013, these capitalized costs were $141 million and $159 million, respectively, which will be liquidated as production units are delivered to the customer.

Our sales contracts in many cases are long-term contracts expected to be performed over periods exceeding twelve months. At December 31, 2014 and 2013, approximately 69% 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.

At December 31, 2014, we had revolving credit agreements with various banks permitting aggregate borrowings of up to $4.35 billion pursuant to a $2.20 billion revolving credit agreement and a $2.15 billion multicurrency revolving credit agreement, both of which expire in May, 2019. As of December 31, 2014, there were no borrowings under either of these revolving credit agreements. The undrawn portions of these revolving credit agreements are also available to serve as backup facilities for the issuance of commercial paper. As of December 31, 2014, our maximum commercial paper borrowing limit was $4.35 billion. We use our commercial paper borrowings for general corporate purposes, including the funding of potential acquisitions and repurchases of our common stock.

The weighted-average interest rates applicable to short-term borrowings outstanding at December 31, 2014 and 2013 were 5.7% and 1.8%, respectively. At December 31, 2014, approximately $816 million was available under short-term lines of credit with local banks at our various domestic and international subsidiaries.

On April 1, 2014, we redeemed all remaining outstanding 2016 Goodrich 6.290% notes, representing approximately $188 million in aggregate principal, under our redemption notice issued on February 28, 2014.

During 2013, we repaid approximately $1,698 million of Goodrich and UTC notes bearing interest ranging from 1.200% to 6.290%, with original maturity dates ranging from 2015 to 2021, under previously disclosed redemptions and tender offers. During 2013, a combined net extinguishment loss of approximately $23 million was recognized within Interest expense, net in the accompanying Consolidated Statements of Operations.

The junior subordinated notes are redeemable at our option, in whole or in part, on a date not earlier than August 1, 2017. The redemption price will be the principal amount, plus accrued and unpaid interest, if any, up to but excluding the redemption date. We may extend or eliminate the optional redemption date as part of a remarketing of the junior subordinated notes which could occur between April 29, 2015 and July 15, 2015 or between July 23, 2015 and July 29, 2015.

§	The three-month LIBOR rate as of December 31, 2014 was approximately 0.2%.

The project financing obligations noted above are associated with the sale of rights to unbilled revenues related to the ongoing activity of an entity owned by UTC Climate, Controls & Security. The percentage of total short-term borrowings and long-term debt at variable interest rates was 4% and 5% at December 31, 2014 and 2013, respectively. Interest rates on our commercial paper borrowings are considered variable due to their short-term duration and high-frequency of turnover.

INCOME TAXES

Income Before Income Taxes. The sources of income from continuing operations before income taxes are:



(dollars in millions)	2014		2013		2012
United States	$	4,270	$	3,658	$	2,595
Foreign	4,617		4,654		4,316
	$	8,887	$	8,312	$	6,911

With few exceptions, U.S. income taxes have not been provided on undistributed earnings of UTC's international subsidiaries. These earnings relate to ongoing operations and were approximately $28 billion as of December 31, 2014. It is not practicable to estimate the amount of tax that might be payable. We intend to reinvest these earnings permanently outside the U.S. or to repatriate the earnings only when it is tax effective to do so.

Provision for Income Taxes. The income tax expense (benefit) for the years ended December 31, 2014, 2013 and 2012 consisted of the following components:

Reconciliation of Effective Income Tax Rate. Differences between effective income tax rates and the statutory U.S. federal income tax rate are as follows:



	2014		2013		2012
Statutory U.S. federal income tax rate	35.0	%	35.0	%	35.0	%
Tax on international activities	(3.4	)%	(5.8	)%	(6.4	)%
Tax audit settlements	(4.2	)%	(0.4	)%	(3.4	)%
Other	(1.9	)%	(1.9	)%	(0.4	)%
Effective income tax rate	25.5	%	26.9	%	24.8	%

The 2014 effective tax rate reflects a favorable tax adjustment of $213 million related to the conclusion of the examination of UTC’s 2009 - 2010 tax years, a favorable tax adjustment of $84 million related to the resolution of disputed tax matters with the Appeals Division of the IRS for UTC’s 2006 - 2008 tax years, a favorable tax impact of $40 million related to the conclusion of the State of Connecticut's review of UTC’s 2010 - 2012 tax years and a favorable tax impact of $34 million related to the conclusion of the Canada Revenue Agency’s examination of the company's research credits claimed in 2006-2012. Also included is a favorable tax adjustment of $175 million associated with management’s decision to repatriate additional high taxed dividends from the current year. These are partially offset by an unfavorable tax adjustment of approximately $265 million related to the 1998 reorganization of the corporate structure of Otis operations in Germany, a matter which is currently in litigation. This is reported in the table above in tax on international activities.

The 2013 effective tax rate reflects a favorable non-cash income tax adjustment of approximately $35 million related to the conclusion of the examination of Goodrich's 2009 - 2010 tax years and resolution of a dispute with the IRS for Goodrich's 2001 - 2006 tax years. In addition, the 2013 effective tax rate also reflects a favorable tax impact of $95 million associated with the legislative corporate tax extenders enacted in January 2013, as part of the American Taxpayer Relief Act of 2012, as well as the favorable tax impact of $24 million related to a U.K. tax rate reduction enacted in July 2013.

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

Deferred Tax Assets and Liabilities. 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, 2014 and 2013 are as follows:



(dollars in millions)	2014			2013
Future income tax benefits:
Insurance and employee benefits	$	1,122		$	747
Other asset basis differences	369			365

Tax credit carryforwards	(58		)	(68		)
Valuation allowances	184			273
	$	2,433		$	3,338

The future income taxes payable balances of $2,433 million and $3,338 million, reflected in the table above, for the years ended December 31, 2014 and 2013, respectively, are reported in accrued liabilities and other long-term liabilities on our Consolidated Balance Sheet.

Valuation allowances have been established primarily for tax credit carryforwards, tax loss carryforwards, and certain foreign temporary differences to reduce the future income tax benefits to expected realizable amounts. The table above reflects reductions in 2014 to tax credit carryforwards and valuation allowances associated with an agreement with a state taxing authority for the monetization of tax credits.

Tax Credit and Loss Carryforwards. At December 31, 2014, tax credit carryforwards, principally state and foreign, and tax loss carryforwards, principally state and foreign, were as follows:



(dollars in millions)	Tax Credit Carryforwards		Tax Loss Carryforwards
Expiration period:
2015-2019	$	29	$	555

2025-2034	243		726
Indefinite	681		2,118
Total	$	963	$	3,641

Unrecognized Tax Benefits. At December 31, 2014, we had gross tax-effected unrecognized tax benefits of $1,089 million, of which, $1,002 million, 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, 2014, 2013 and 2012 is as follows:



(dollars in millions)	2014			2013			2012
Balance at January 1	$	1,223		$	1,073		$	946
Additions for tax positions related to the current year	164			113			232
Additions for tax positions of prior years	435			211			221
Reductions for tax positions of prior years	(47		)	(41		)	(21		)
Settlements	(686		)	(133		)	(305		)
Balance at December 31	$	1,089		$	1,223		$	1,073
Gross interest expense related to unrecognized tax benefits	$	180		$	51		$	40
Total accrued interest balance at December 31	$	292		$	262		$	270

Included in the balance at December 31, 2014 is $87 million of tax positions whose tax characterization is highly certain but for which there is uncertainty about the timing of tax return inclusion. Because of the impact of deferred tax accounting, other than interest and penalties, the timing would not impact the annual effective tax rate but could accelerate the payment of cash to the taxing authority to an earlier period.

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, Brazil, Canada, China, France, Germany, Hong Kong, India, Italy, Japan, Singapore, South Korea, 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 2003.

During the quarter ended December 31, 2014, the Company resolved certain litigation and Internal Revenue Service (IRS) Appeals proceedings related to an issue involving the proper timing of deductions taken by Goodrich Corporation in its tax years 2005 through 2010, prior to its acquisition by UTC. As a result, the Company recognized non-cash gains of approximately $93 million during the fourth quarter of 2014, primarily comprised of pre-tax interest.

During the quarter ended September 30, 2014, IRS Appeals proceedings for UTC tax years 2006 through 2008 were completed. Additionally, during the quarter ended September 30, 2014, an agreement was reached between the Company and the Canada Revenue Agency (CRA) with respect to the amount of the research credits to which the Company was entitled for tax years 2006 through 2012. As a result of the completed IRS Appeals activity and agreement with the CRA, the Company recognized predominantly non-cash gains of approximately $141 million, including a pre-tax interest adjustment of $23 million. Additionally, during the third quarter of 2014, the IRS commenced audits of UTC tax years 2011 and 2012 as well as pre-acquisition Goodrich tax years 2011 and 2012 through the date of acquisition by UTC, both of which are expected to continue beyond the next twelve months.

During the quarter ended June 30, 2014, the Examination Division of the IRS completed a review of UTC tax years 2009 and 2010 and the Examination Division of the Connecticut Department of Revenue Services completed a review of UTC’s tax years 2010 through 2012. As a result of the completion of these examinations, the Company recognized predominantly non-cash gains of approximately $274 million, including a pre-tax interest adjustment of $21 million. The Company also reached an agreement with a state taxing authority during the second quarter of 2014 for the monetization of tax credits resulting in a gain of approximately $220 million through Other income, net in the quarter ended June 30, 2014. Additionally, a dispute related to a proposed disallowance of certain deductions claimed in France for tax years 2008 through 2011 was settled with the French Tax Authority during the quarter ended June 30, 2014 consistent with reserves that had been established for the matter.

During 2013, the Company recognized a predominantly non-cash settlement gain of approximately $34 million for interest relating to the closure of IRS audits of UTC through 2005. During 2013, the IRS also completed examination activity of Goodrich tax years 2009 and 2010, prior to its acquisition by UTC, resulting in a non-cash settlement gain of approximately $24 million, including $2 million of interest. Additionally, certain litigation regarding the proper timing of deductions taken by Goodrich in its tax years 2001 and 2002, prior to its acquisition by UTC, was resolved in 2013 resulting in recognition of a non-cash settlement gain of approximately $25 million, including $12 million of interest.

During 2012, the IRS completed examination fieldwork for our 2006 through 2008 tax years and issued its audit report. During 2012, we also reached final resolution with the Appeals Division of the IRS for our 2004 and 2005 tax years regarding certain proposed adjustments with which we did not agree. As a result of the above described events with respect to our 2004 - 2005 and 2006 - 2008 tax years, we recorded reductions in tax expense in 2012 in the aggregate amount of $237 million.

It is reasonably possible that over the next 12 months the amount of unrecognized tax benefits may change within a range of a net increase of $95 million to a net decrease of $445 million as a result of additional worldwide uncertain tax positions, the revaluation of current uncertain tax positions arising from developments in examinations, in appeals, or in the courts, or the closure of tax statutes.

See Note 17, Contingent Liabilities, for discussion regarding uncertain tax positions, included in the above range, related to pending litigation with respect to certain deductions claimed in Germany.

Employee Benefits and Share-based Compensation [Abstract]

Employee Benefit Plans

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 $330 million, $335 million and $256 million for 2014, 2013 and 2012, respectively.

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

Shares of common stock are allocated to employees' ESOP accounts at fair value on the date earned. Cash dividends on common stock held by the ESOP are used for debt service payments. Participants receive additional shares in lieu of cash dividends. Common stock allocated to ESOP participants is included in the average number of common shares outstanding for both basic and diluted earnings per share. At December 31, 2014, 29.9 million common shares had been allocated to employees, leaving 14.2 million unallocated common shares in the ESOP Trust, with an approximate fair value of $1.6 billion.

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

Net actuarial loss	$	9,068		$	5,261
Prior service credit	(27		)	(37		)
Net amount recognized	$	9,041		$	5,224

Included within "Actuarial loss (gain)" in the Change in Benefit Obligation in 2014 above, is a $1.1 billion increase to the projected benefit obligation resulting from the adoption of the new mortality base table (RP-2014) with projection scale (MP-2014) that was published by the Society of Actuaries in 2014. The amounts included in "Other" in the preceding table primarily reflect the impact of foreign exchange translation, primarily for plans in the U.K. and Canada.

In 2014, we offered a voluntary lump-sum pension payout program to certain eligible terminated vested participants (generally any terminated vested participant with a lump sum value of $50,000 or less) that would settle our obligation to those participants accepting the offer. The program provides participants with a one-time choice of electing to receive a lump-sum settlement in lieu of receiving a future monthly pension benefit. Payments to participants who accepted the offer began in 2014 and will be completed in early 2015. In 2014, as part of this voluntary lump sum program, the Company settled $311 million of its projected benefit obligation, and expects to settle approximately another $147 million in early 2015.

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

We made $200 million of cash contributions to our domestic defined benefit pension plans and made $317 million of cash contributions to our foreign defined benefit pension plans in 2014. In 2013, we made no significant contributions to our domestic defined benefit pension plans and made $108 million of cash contributions to our foreign defined benefit pension plans.

Information for pension plans with accumulated benefit obligations in excess of plan assets:



(dollars in millions)	2014		2013

	$	875

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
	2014		2013		2014		2013		2012
Discount rate	3.8	%	4.7	%	4.7	%	4.0	%	4.6	%
Salary scale	4.2	%	4.2	%	4.2	%	4.2	%	4.3	%
Expected return on plan assets	—		—		7.6	%	7.7	%	7.7	%

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

The plans' investment management objectives include maintaining an adequate level of diversification, reducing interest rate and market risk, and providing adequate liquidity to meet immediate and future benefit payment requirements. Globally, investment strategies target a mix of 55% to 65% of growth seeking assets and 35% to 45% income generating and hedging 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, approximately 10% of the total investment portfolio is an enhanced equity strategy that invests in publicly traded equity and fixed income securities, derivatives and foreign currency. Investments in private equity are primarily via limited partnership interests in buy-out strategies with smaller allocations to distressed debt funds. The real estate strategy is principally concentrated in directly held U.S. core investments with some smaller investments in international, value-added and opportunistic strategies. Within the income generating assets, the fixed income portfolio consists of mainly government and broadly diversified high quality corporate bonds.

The plans have continued their pension risk management techniques designed to reduce the plan's interest rate risk. More specifically, the plans have incorporated liability hedging programs that include the adoption of a risk reduction objective as part of the long-term investment strategy. Under this objective the interest rate hedge is dynamically increased as funded status improves. The hedging programs incorporate a range of assets and investment tools, each with ranging interest rate sensitivity. The investment portfolios are currently hedging approximately 35% to 45% of the interest rate sensitivity of the pension plan liabilities.

The fair values of pension plan assets at December 31, 2014 and 2013 by asset category are as follows:

A portion of the portfolio may include long-short market neutral and relative value strategies that invest in publicly traded, equity and fixed income securities, as well as derivatives of equity and fixed income securities and foreign currency.


Note 3	Represents limited partner investments with general partners that primarily invest in debt and equity.


Note 4	Represents mortgage and asset-backed securities.


Note 5	Represents investments in real estate including commingled funds and directly held properties.

Note 7	Represents short-term commercial paper, bonds and other cash or cash-like instruments.


Note 8	Represents trust receivables and payables that are not leveled.

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 3% of total plan assets at December 31, 2014 and 2013. 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:



(dollars in millions)	Enhanced Global Equities			Private Equities			Corporate Bonds		Real Estate			Total

Balance, December 31, 2014	$	525		$	1,400		$	309	$	1,913		$	4,147

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

Although we are not required to make additional contributions to our domestic defined benefit pension plans through the end of 2019, we may elect to make discretionary contributions in 2015. We expect to make total contributions of approximately $350 million to our global defined benefit pension plans in 2015, including discretionary contributions of approximately $200 million to our domestic defined benefit pension plans. 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: $1,994 million in 2015, $1,824 million in 2016, $1,895 million in 2017, $1,975 million in 2018, $2,040 million in 2019, and $11,091 million from 2020 through 2024.

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

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

The components of net periodic benefit cost are as follows:

The estimated amounts that will be amortized from accumulated other comprehensive loss into net periodic benefit cost in 2015 include actuarial net gains of $4 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
	2014		2013		2014		2013		2012
Discount rate	3.8	%	4.4	%	4.4	%	3.6	%	4.2	%

Assumed health care cost trend rates are as follows:

Rate that the cost trend rate gradually declines to	5.0	%	5.0	%
Year that the rate reaches the rate it is assumed to remain at	2019		2019

Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. A one-percentage-point change in assumed health care cost trend rates would have the following effects:



	2014 One-Percentage-Point

Effect on total service and interest cost	$	3	$	(3	)
Effect on postretirement benefit obligation	54		(46		)

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: $89 million in 2015, $86 million in 2016, $81 million in 2017, $75 million in 2018, $69 million in 2019, and $281 million from 2020 through 2024.

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 2014 and 2013 is for the plan's year-end at June 30, 2013, and June 30, 2012, 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% 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
Pension Fund	EIN/Pension Plan Number	2014	2013	Pending/ Implemented	2014		2013		2012		Surcharge Imposed	Expiration Date of Collective-Bargaining Agreement
National Elevator Industry Pension Plan	23-2694291	Green	Green	No	$	79	$	71	$	63	No	July 8, 2017
Other funds					34		34		36
					$	113	$	105	$	99

For the plan years ended June 30, 2013 and 2012, respectively, we were listed in the National Elevator Industry Pension Plan's Forms 5500 as providing more than 5% of the total contributions for the plan. At the date these financial statements were issued, Forms 5500 were not available for the plan year ending June 30, 2014.

In addition, we participate in several multiemployer arrangements that provide postretirement benefits other than pensions, with the National Elevator Industry Health Benefit Plan being the most significant. These arrangements generally provide medical and life benefits for eligible active employees and retirees and their dependents. Contributions to multiemployer plans that provide postretirement benefits other than pensions were $14 million, $12 million and $11 million for 2014, 2013 and 2012, respectively.

Stock-based Compensation. UTC's long-term incentive plan authorizes various types of market and performance based incentive awards that may be granted to officers and employees. Our Long-Term Incentive Plan (LTIP) was amended and restated effective April 28, 2014. Since the LTIP's inception in 2005, a total of 149 million shares have been authorized for issuance pursuant to awards under the LTIP. All equity-based compensation awards are made exclusively through the LTIP. As of December 31, 2014, approximately 53 million shares remain available for awards under the LTIP. The LTIP does not contain an aggregate annual award limit. We expect that the shares awarded on an annual basis will range from 1.0% to 1.5% of shares outstanding. The LTIP will expire after all shares have been awarded or April 30, 2020, whichever is sooner.

Under the LTIP and predecessor 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 may become vested and exercisable subject to certain terms and conditions. LTIP awards with performance-based vesting generally have a minimum three-year vesting period and vest based on performance against pre-established metrics. In the event of retirement, vesting for awards held more than one year does not accelerate but may vest as scheduled based on actual performance relative to target metrics. We have historically repurchased shares of our common stock in an amount at least equal to the number of shares issued under our equity compensation arrangements and will continue to evaluate this policy in conjunction with our overall share repurchase program.

We measure the cost of all share-based payments, including stock options, at fair value on the grant date and recognize this cost in the Consolidated Statement of Operations. For the years ended December 31, 2014, 2013 and 2012, $240 million, $275 million and $210 million, respectively, of compensation cost was recognized in operating results. The associated future income tax benefit recognized was $80 million, $97 million and $76 million for the years ended December 31, 2014, 2013 and 2012, respectively.

For the years ended December 31, 2014, 2013 and 2012, the amount of cash received from the exercise of stock options was $187 million, $378 million and $381 million, respectively, with an associated tax benefit realized of $125 million, $194 million and $111 million, respectively. In addition, for the years ended December 31, 2014, 2013 and 2012, the associated tax benefit realized from the vesting of performance share units and other restricted awards was $49 million, $26 million and $15 million, respectively. Also, in accordance with the Compensation—Stock Compensation Topic of the FASB ASC, for the years ended December 31, 2014, 2013 and 2012, $103 million, $115 million and $67 million, respectively, of certain tax benefits have been reported as operating cash outflows with corresponding cash inflows from financing activities.

At December 31, 2014, there was $182 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, 2014 follows:

The weighted-average grant date fair value of stock options and stock appreciation rights granted during 2014, 2013, and 2012 was $28.36, $19.91 and $19.32, respectively. The weighted-average grant date fair value of performance share units, which vest upon achieving certain performance metrics, granted during 2014, 2013, and 2012 was $125.41, $91.71 and $82.15, respectively. The total fair value of awards vested during the years ended December 31, 2014, 2013 and 2012 was $226 million, $219 million and $187 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, 2014, 2013 and 2012 was $425 million, $608 million and $370 million, respectively. The total intrinsic value (which is the stock price at vesting) of performance share units and other restricted awards vested was $154 million, $75 million and $46 million during the years ended December 31, 2014, 2013 and 2012, 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, 2014:

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, 2014, 2013 and 2012. Lattice-based option models incorporate ranges of assumptions for inputs, those ranges are as follows:



	2014		2013		2012
Expected volatility	22% - 26%		26% - 27%		30% - 35%
Weighted-average volatility	26	%	27	%	30	%
Expected term (in years)	7.6 - 8.0		7.3 - 7.6		7.4 - 7.7
Expected dividends	2.2	%	2.6	%	2.3	%
Risk-free rate	0.0% - 3.1%		0.1% - 1.9%		0.0% - 2.0%

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

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Instruments

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.

The four quarter rolling average of the notional amount of foreign exchange contracts hedging foreign currency transactions was $13.9 billion and $12.3 billion at December 31, 2014 and 2013, respectively. Additional information pertaining to foreign exchange and hedging activities is included in Note 1.

The following table summarizes the fair value of derivative instruments as of December 31, 2014 and 2013 which consist solely of foreign exchange contracts:



	Asset Derivatives				Liability Derivatives
(dollars in millions)	2014		2013		2014		2013
Derivatives designated as hedging instruments	$	3	$	59	$	248	$	103
Derivatives not designated as hedging instruments	139		31		71		54

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



	Year Ended December 31,
(dollars in millions)	2014			2013
Loss recorded in Accumulated other comprehensive loss	$	(263	)	$	(136	)
Loss reclassified from Accumulated other comprehensive loss into Product sales (effective portion)	$	96		$	25

Assuming current market conditions continue, a $121 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, 2014, all derivative contracts accounted for as cash flow hedges mature by January 2017.

We recognized a gain of $51 million and $22 million in Other income, net on the Consolidated Statement of Operations from foreign exchange contracts not designated as hedging instruments in 2014 and 2013, respectively.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

FAIR VALUE MEASUREMENTS

The Fair Value Measurements and Disclosures Topic of the FASB ASC establishes a valuation hierarchy for disclosure of the inputs to the valuations used to measure 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. This hierarchy prioritizes the inputs into three broad levels as follows:


▪	Level 1 - quoted prices in active markets for identical assets or liabilities;


▪	Level 2 - inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly;


▪	Level 3 - unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value.

The following table provides the assets and liabilities carried at fair value measured on a recurring and nonrecurring basis as of December 31, 2014 and 2013:



2014 (dollars in millions)	Total			Level 1		Level 2			Level 3
Recurring fair value measurements:

We have recorded net gains of approximately $23 million, including a $48 million gain during 2014, as a result of fair value adjustments related to the acquisition of the majority interest in a Pratt & Whitney joint venture. During 2014, we also recorded an approximately $30 million net gain from UTC Climate, Controls & Security's ongoing portfolio transformation, primarily due to a gain on the sale of an interest in a joint venture in North America, and a charge of approximately $28 million to adjust the fair value of a Sikorsky joint venture investment.

During 2013, we recorded an approximately $55 million net gain from UTC Climate, Controls & Security's portfolio transformation, primarily due to a gain on the sale of businesses in Hong Kong and Australia. In addition, we recorded an approximately $193 million gain from the sale of Pratt & Whitney Power Systems business (see Note 2), as well as an approximately $25 million charge to adjust the fair value of a Pratt & Whitney joint venture investment.

Valuation Techniques. Our available-for-sale securities include equity investments that are traded in active markets, either domestically or internationally and are measured at fair value using closing stock prices from active markets. 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. As of December 31, 2014, there were no significant transfers in and out of Level 1 and Level 2.

As of December 31, 2014, 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, 2014 and 2013:

GUARANTEES

We extend a variety of financial guarantees to third parties. As of December 31, 2014 and 2013, the following financial guarantees were outstanding:



	December 31, 2014				December 31, 2013
(dollars in millions)	Maximum Potential Payment		Carrying Amount of Liability		Maximum Potential Payment		Carrying Amount of Liability
Commercial aerospace financing arrangements (see Note 5)	$	632	$	21	$	615	$	25

Performance guarantees	136		—		150		—

As disclosed in Note 3, we completed the sale of substantially all operations of Rocketdyne to GenCorp Inc. on June 14, 2013. Following the sale, certain guarantees of Rocketdyne's performance under existing contracts remain in place, which resulted in an increase in our performance guarantees of approximately $81 million, with no associated significant carrying amount of a liability as of December 31, 2014.

We also have obligations arising from sales of certain businesses and assets, including those from representations and warranties and related indemnities for environmental, health and safety, tax and employment matters. The maximum potential payment related to these obligations is not a specified amount as a number of the obligations do not contain financial caps. The carrying amount of liabilities related to these obligations was $186 million and $189 million at December 31, 2014 and 2013, respectively. For additional information regarding the environmental indemnifications, see Note 17.

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 the FASB ASC we record these liabilities at fair value.

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, 2014 and 2013 are as follows:

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities	CONTINGENT LIABILITIES Except as otherwise noted, while we are unable to predict the final outcome, based on information currently available, we do not believe that resolution of any of the following matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition. Leases. We occupy space and use certain equipment under lease arrangements. Rental commitments of $2,525 million at December 31, 2014 under long-term non-cancelable operating leases are payable as follows: $593 million in 2015, $479 million in 2016, $340 million in 2017, $235 million in 2018, $171 million in 2019 and $707 million thereafter. Rent expense was $464 million in 2014, $456 million in 2013 and $457 million in 2012. Additional information pertaining to commercial aerospace rental commitments is included in Note 5 to the Consolidated Financial Statements. Environmental. Our operations are subject to environmental regulation by federal, state and local authorities in the United States and regulatory authorities with jurisdiction over our foreign operations. As described in Note 1 to the Consolidated Financial Statements, we have accrued for the costs of environmental remediation activities and periodically reassess these amounts. We believe that the likelihood of incurring losses materially in excess of amounts accrued is remote. As of December 31, 2014 and 2013, we had $903 million and $936 million reserved for environmental remediation, respectively. 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, or that certain payments be delayed or withheld. 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. Legal Proceedings. F100 Engine Litigation As previously disclosed, the United States Government sued us in 1999 in the United States District Court for the Southern District of Ohio, claiming that Pratt & Whitney violated the civil False Claims Act and common law. The claims relate to the “Fighter Engine Competition” between Pratt & Whitney's F100 engine and General Electric's F110 engine. The government alleged that it 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, which ended in April, 2005, the government claimed Pratt & Whitney's liability to be approximately $624 million. On August 1, 2008, the trial court held that the Air Force had not suffered any actual damages because Pratt & Whitney had made significant price concessions after the alleged overstatements were made. However, the trial court judge found that Pratt & Whitney violated the False Claims Act due to inaccurate statements contained in its 1983 initial engine pricing proposal. In the absence of actual damages, the trial court awarded the government the maximum civil penalty of approximately $7 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 government and UTC appealed the decision to the United States Court of Appeals for the Sixth Circuit. On November 18, 2010, the Sixth Circuit affirmed Pratt & Whitney's liability for the civil penalty under the False Claims Act, but remanded the case to the trial court for further proceedings on the issues of False Claims Act damages and common law liability and damages. On June 18, 2012, the trial court found that Pratt & Whitney had breached obligations imposed by common law based on the same conduct with respect to which the court previously found liability under the False Claims Act. Under the common law claims, the U.S. Air Force is entitled to seek damages for events occurring before March 3, 1989, which are not recoverable under the False Claims Act. On June 17, 2013, the trial court awarded the government approximately $473 million in damages and penalties, plus prejudgment interest in an amount to be determined. On July 1, 2013, the trial court, after determining the amount of prejudgment interest, entered judgment in favor of the government in the amount of approximately $664 million. The trial court also awarded postjudgment interest on the full amount of the judgment to accrue from July 2, 2013, at the federal variable interest rate determined pursuant to 28 U.S.C. § 1961. The judgment included four different components of damages: (1) common law damages of approximately $109 million; (2) prejudgment interest on common law damages of approximately $191 million; (3) False Claims Act treble damages of approximately $357 million; and (4) penalties of approximately $7 million. The penalty component of the judgment previously was affirmed by the United States Court of Appeals in 2010. We strongly disagree with the trial court's analysis and conclusions. We filed an appeal from the judgment to the United States Court of Appeals for the Sixth Circuit on August 26, 2013. Oral argument in the appeal was held on December 2, 2014, and a decision from the Sixth Circuit is expected in early 2015. Based on our analysis, we continue to believe that there is no basis for any common law liability for the inaccurate statements. We also believe that the government suffered no actual damages as a result of the inaccurate statements made in 1983 and, therefore, there is no basis in fact or law for the award of common law damages, prejudgment interest or False Claims Act treble damages. If, contrary to our expectations, all or any portion of the judgment should ultimately be affirmed, we estimate a range of reasonably possible loss from approximately $24 million to $657 million in excess of amounts previously accrued, plus postjudgment interest. The outcome of this matter could result in a material adverse effect on our results of operations in the period in which a liability would be recognized and cash flows for the period in which damages would be paid. Cost Accounting Standards Claims As previously disclosed, in December 2008, the Department of Defense (DOD) issued a contract claim against Sikorsky to recover overpayments the DOD alleges that it made to Sikorsky 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 claimed that Sikorsky's liability was approximately $100 million (including interest through December 31, 2014). We believed this claim was without merit and Sikorsky filed an appeal in December 2009 with the U.S. Court of Federal Claims. Trial in the matter concluded in January 2013 and on March 22, 2013, the U.S. Court of Federal Claims issued a written decision in favor of Sikorsky determining that the DOD had failed to prove its claims because Sikorsky's calculation of material overhead complied with the cost accounting standards. DOD appealed this decision to the United States Court of Appeals for the Federal Circuit. On December 10, 2014, the Federal Circuit affirmed the judgment of the U.S. Court of Federal Claims in favor of Sikorsky. By letter dated December 24, 2013, a Divisional Administrative Contracting Officer of the United States Defense Contract Management Agency asserted a claim and demand for payment of $210,968,414 against Pratt & Whitney. The claim is based on Pratt & Whitney's alleged noncompliance with cost accounting standards from January 1, 2005 to December 31, 2012, due to its method of determining the cost of collaborator parts used in the calculation of material overhead costs for government contracts. On March 18, 2014, Pratt & Whitney filed an appeal to the Armed Services Board of Contract Appeals. Pratt & Whitney’s appeal is still pending and we continue to believe the government’s claim is without merit. German Tax Litigation As previously disclosed, UTC has been involved in administrative review proceedings with the German Tax Office, which concern approximately €215 million (approximately $265 million) of tax benefits that we have claimed related to a 1998 reorganization of the corporate structure of Otis operations in Germany. Upon audit, these tax benefits were disallowed by the German Tax Office. UTC estimates interest associated with the aforementioned tax benefits is an additional approximately €115 million (approximately $140 million). On August 3, 2012, we filed suit in the local German Tax Court (Berlin-Brandenburg). In 2008 the German Federal Tax Court (FTC) denied benefits to another taxpayer in a case involving a German tax law relevant to our reorganization. The determination of the FTC on this other matter was appealed to the European Court of Justice (ECJ) to determine if the underlying German tax law is violative of European Union principles. On September 17, 2009, the ECJ issued an opinion in this case that is generally favorable to the other taxpayer and referred the case back to the FTC for further consideration of certain related issues. In May 2010, the FTC released its decision, in which it resolved certain tax issues that may be relevant to our suit and remanded the case to a lower court for further development. In 2012, the lower court decided in favor of the other taxpayer and the German Government again appealed the findings to the FTC. In November 2014, the FTC ruled in favor of the German Government, and against the other taxpayer. The FTC decision in the case involving the other taxpayer is not determinative of the outcome in our case and we will continue vigorously to litigate the matter. However, in light of the FTC decision in the case involving the other taxpayer, we have fully accrued for the matter during the quarter ended December 31, 2014. Other. As described in Note 16 to the Consolidated Financial Statements, we extend performance and operating cost guarantees beyond our normal warranty and service policies for extended periods on some of our products. We have accrued our estimate of the liability that may result under these guarantees and for service costs that are probable and can be reasonably estimated. We have accrued for environmental investigatory, remediation, operating and maintenance costs, performance guarantees and other litigation and claims based on our estimate of the probable outcome of these matters. While it is possible that the outcome of these matters may differ from the recorded liability, we believe that resolution of these matters will not have a material impact on our competitive position, results of operations, cash flows or financial condition. We also have other commitments and contingent liabilities related to legal proceedings, self-insurance programs and matters arising out of the normal course of business. We accrue contingencies based upon a range of possible outcomes. If no amount within this range is a better estimate than any other, then we accrue the minimum amount. We are also subject to a number of routine lawsuits, investigations and claims (some of which involve substantial amounts) arising out of the ordinary course of our business. We do not believe that these matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition.

Multiemployer Plans [Line Items]
Multiemployer Plans General Nature	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.

Department of Defense Contract Claim Against Sikorsky [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	December 2008
Loss Contingency Allegations	As previously disclosed, in December 2008, the Department of Defense (DOD) issued a contract claim against Sikorsky to recover overpayments the DOD alleges that it made to Sikorsky 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 claimed that Sikorsky's liability was approximately $100 million (including interest through December 31, 2014).
Loss Contingency Damages Sought	$100 million (including interest through December 31, 2014)
Loss Contingency, Settlement Agreement, Date	3/22/2013
Loss Contingency Actions Taken By Court Arbitrator Or Mediator	On December 10, 2014, the Federal Circuit affirmed the judgment of the U.S. Court of Federal Claims in favor of Sikorsky.
Loss Contingency Actions Taken By Plaintiff And Defendant	We believed this claim was without merit and Sikorsky filed an appeal in December 2009 with the U.S. Court of Federal Claims. Trial in the matter concluded in January 2013 and on March 22, 2013, the U.S. Court of Federal Claims issued a written decision in favor of Sikorsky determining that the DOD had failed to prove its claims because Sikorsky's calculation of material overhead complied with the cost accounting standards. DOD appealed this decision to the United States Court of Appeals for the Federal Circuit.
Department of Justice Lawsuit Against Pratt and Whitney [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	1999
Loss Contingency, Damages Sought, Value	$ 624
Loss Contingency Allegations	As previously disclosed, the United States Government sued us in 1999 in the United States District Court for the Southern District of Ohio, claiming that Pratt & Whitney violated the civil False Claims Act and common law. The claims relate to the “Fighter Engine Competition” between Pratt & Whitney's F100 engine and General Electric's F110 engine. The government alleged that it 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, which ended in April, 2005, the government claimed Pratt & Whitney's liability to be approximately $624 million.
Loss Contingency Period Of Occurrence	fiscal years 1985 through 1990
Loss Contingency, Range of Possible Loss, Minimum	$ 24
Loss Contingency, Range of Possible Loss, Maximum	657
Loss Contingency Damages Awarded Value ,Not Including Interest	$ 473
Loss Contingency, Settlement Agreement, Date	6/17/2013
Loss Contingency Actions Taken By Court Arbitrator Or Mediator	On August 1, 2008, the trial court held that the Air Force had not suffered any actual damages because Pratt & Whitney had made significant price concessions after the alleged overstatements were made. However, the trial court judge found that Pratt & Whitney violated the False Claims Act due to inaccurate statements contained in its 1983 initial engine pricing proposal. In the absence of actual damages, the trial court awarded the government the maximum civil penalty of approximately $7 million, or $10,000 for each of the 709 invoices Pratt & Whitney submitted in 1989 and later under the contracts.
Loss Contingency Actions Taken By Plaintiff And Defendant	In September 2008, both the government and UTC appealed the decision to the United States Court of Appeals for the Sixth Circuit. On November 18, 2010, the Sixth Circuit affirmed Pratt & Whitney's liability for the civil penalty under the False Claims Act, but remanded the case to the trial court for further proceedings on the issues of False Claims Act damages and common law liability and damages.
Loss Contingency Actions Taken By Defendant	We strongly disagree with the trial court's analysis and conclusions. We filed an appeal from the judgment to the United States Court of Appeals for the Sixth Circuit on August 26, 2013. Oral argument in the appeal was held on December 2, 2014, and a decision from the Sixth Circuit is expected in early 2015. Based on our analysis, we continue to believe that there is no basis for any common law liability for the inaccurate statements. We also believe that the government suffered no actual damages as a result of the inaccurate statements made in 1983 and, therefore, there is no basis in fact or law for the award of common law damages, prejudgment interest or False Claims Act treble damages. If, contrary to our expectations, all or any portion of the judgment should ultimately be affirmed, we estimate a range of reasonably possible loss from approximately $24 million to $657 million in excess of amounts previously accrued, plus postjudgment interest. The outcome of this matter could result in a material adverse effect on our results of operations in the period in which a liability would be recognized and cash flows for the period in which damages would be paid.
Loss Contingency, Settlement Agreement, Terms	On June 17, 2013, the trial court awarded the government approximately $473 million in damages and penalties, plus prejudgment interest in an amount to be determined. On July 1, 2013, the trial court, after determining the amount of prejudgment interest, entered judgment in favor of the government in the amount of approximately $664 million. The trial court also awarded postjudgment interest on the full amount of the judgment to accrue from July 2, 2013, at the federal variable interest rate determined pursuant to 28 U.S.C. § 1961. The judgment included four different components of damages: (1) common law damages of approximately $109 million; (2) prejudgment interest on common law damages of approximately $191 million; (3) False Claims Act treble damages of approximately $357 million; and (4) penalties of approximately $7 million. The penalty component of the judgment previously was affirmed by the United States Court of Appeals in 2010.

Loss Contingency, Additional Actions Taken by Court, Arbitrator or Mediator	On June 18, 2012, the trial court found that Pratt & Whitney had breached obligations imposed by common law based on the same conduct with respect to which the court previously found liability under the False Claims Act. Under the common law claims, the U.S. Air Force is entitled to seek damages for events occurring before March 3, 1989, which are not recoverable under the False Claims Act.
German Tax Office Against Otis [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	8/3/2012
Loss Contingency Allegations	As previously disclosed, UTC has been involved in administrative review proceedings with the German Tax Office, which concern approximately €215 million (approximately $265 million) of tax benefits that we have claimed related to a 1998 reorganization of the corporate structure of Otis operations in Germany. Upon audit, these tax benefits were disallowed by the German Tax Office. UTC estimates interest associated with the aforementioned tax benefits is an additional approximately €115 million (approximately $140 million).
Loss Contingency Damages Sought	€215 million (approximately $265 million)
Loss Contingency Actions Taken By Plaintiff And Defendant	On August 3, 2012, we filed suit in the local German Tax Court (Berlin-Brandenburg). In 2008 the German Federal Tax Court (FTC) denied benefits to another taxpayer in a case involving a German tax law relevant to our reorganization. The determination of the FTC on this other matter was appealed to the European Court of Justice (ECJ) to determine if the underlying German tax law is violative of European Union principles. On September 17, 2009, the ECJ issued an opinion in this case that is generally favorable to the other taxpayer and referred the case back to the FTC for further consideration of certain related issues. In May 2010, the FTC released its decision, in which it resolved certain tax issues that may be relevant to our suit and remanded the case to a lower court for further development. In 2012, the lower court decided in favor of the other taxpayer and the German Government again appealed the findings to the FTC.
Loss Contingency, Interest	€115 million (approximately $140 million)
Loss Contingency, Management's Assessment and Process	In November 2014, the FTC ruled in favor of the German Government, and against the other taxpayer. The FTC decision in the case involving the other taxpayer is not determinative of the outcome in our case and we will continue vigorously to litigate the matter. However, in light of the FTC decision in the case involving the other taxpayer, we have fully accrued for the matter during the quarter ended December 31, 2014.

Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date	December 24, 2013
Loss Contingency Allegations	By letter dated December 24, 2013, a Divisional Administrative Contracting Officer of the United States Defense Contract Management Agency asserted a claim and demand for payment of $210,968,414 against Pratt & Whitney. The claim is based on Pratt & Whitney's alleged noncompliance with cost accounting standards from January 1, 2005 to December 31, 2012, due to its method of determining the cost of collaborator parts used in the calculation of material overhead costs for government contracts.
Loss Contingency Damages Sought	$ 210,968,414
Loss Contingency Actions Taken By Defendant	On March 18, 2014, Pratt & Whitney filed an appeal to the Armed Services Board of Contract Appeals. Pratt & Whitney’s appeal is still pending and we continue to believe the government’s claim is without merit.
