NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
The Condensed Consolidated Financial Statements at March 31,September 30, 2018 and for the quartersquarter and nine months ended March 31,September 30, 2018 and 2017 are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the results for the interim periods. The results reported in these Condensed Consolidated Financial Statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the financial statements and notes in our Annual Report to Shareowners (2017 Annual Report) incorporated by reference in our Annual Report on Form 10-K for calendar year 2017 (2017 Form 10-K).
Note 1: Acquisitions, Dispositions, Goodwill and Other Intangible Assets
Business Acquisitions and Dispositions. During the threenine months ended March 31,September 30, 2018, our investment in business acquisitions was $125$177 million, and primarily consisted of an acquisition at Pratt & Whitney. On June 21, 2018, UTC Climate, Controls & Security completed its sale of Taylor Company for proceeds of $1.0 billion resulting in a pre-tax gain of $799 million ($591 million after tax).
On September 4, 2017, we announced that we had entered into a merger agreement with Rockwell Collins, Inc. (Rockwell Collins), under which we agreed to acquire Rockwell Collins. Under the terms of the merger agreement, each Rockwell Collins shareowner will receive $93.33 per share in cash and a fraction of a share of UTC common stock equal to the quotient obtained by dividing $46.67 by the average of the volume-weighted average prices per share of UTC common stock on the NYSE on each of the 20 consecutive trading days ending with the trading day immediately prior to the closing date, (the “UTC Stock Price”), subject to adjustment based on a two-way collar mechanism as described below (the “Stock Consideration”). The cash and UTC stock payable in exchange for each such share of Rockwell Collins common stock are collectively the “Merger Consideration.” The fraction of a share of UTC common stock into which each such share of Rockwell Collins common stock will be converted is the “Exchange Ratio.” The Exchange Ratio will be determined based upon the UTC Stock Price. If the UTC Stock Price is greater than $107.01 but less than $124.37, the Exchange Ratio will be equal to the quotient of (i) $46.67 divided by (ii) the UTC Stock Price, which, in each case, will result in the Stock Consideration having a value equal to $46.67. If the UTC Stock Price is less than or equal to $107.01 or greater than or equal to $124.37, then a two-way collar mechanism will apply, pursuant to which, (x) if the UTC Stock Price is greater than or equal to $124.37, the Exchange Ratio will be fixed at 0.37525 and the value of the Stock Consideration will be greater than $46.67, and (y) if the UTC Stock Price is less than or equal to $107.01, the Exchange Ratio will be fixed at 0.43613 and the value of the Stock Consideration will be less than $46.67. On January 11, 2018, the merger was approved by Rockwell Collins' shareowners. We currently expect that the merger will be completed mid-yearin the fourth quarter of 2018, subject to customary closing conditions, including the receipt of required regulatory approvals.
We anticipate that approximately $15 billion will be required to pay the aggregate cash portion of the Merger Consideration. We expectConsideration which will be funded by cash on hand. On August 16, 2018 we issued $11 billion of aggregate principal notes (refer to Note 5) for net proceeds of $10.9 billion of which $9.2 billion is specifically designated to fund the cash portion of the Merger Consideration through debt issuances and related fees, expenses and other amounts. Therefore, $9.2 billion of the net proceeds from the issuance have been classified as restricted cash as of September 30, 2018.
In connection with the merger agreement with Rockwell Collins announced on hand. Additionally,September 4, 2017, we have entered into a $6.5 billion 364-day unsecured bridge loan credit agreement that would behave been funded only to the extent certain anticipated debt issuances arewere not completed prior to the completion of the merger. The unsecured bridge loan credit agreement was terminated on August 16, 2018 upon issuance of the $11 billion of aggregate principal notes described above. We expect to assume approximately $7 billion of Rockwell Collins' outstanding debt upon completion of the merger.
As has been previously disclosed, the Company is continuing a strategic review of its portfolio of businesses. There can be no assurance as to the outcome of any such process or that any such process will result in a transaction, or if a transaction is undertaken, as to its terms or timing.

The $316 million net reduction in goodwill within Foreign Currency Translation and Other includes a $151 million reduction of goodwill attributable to UTC Climate, Controls & Security's sale of Taylor Company. The $20 million increase in goodwill within Eliminations and other is due to an acquisition of a digital analytics company.

Customer relationship intangible assets include payments made to our customers to secure certain contractual rights. Such payments are capitalized when distinct rights are obtained and sufficient incremental cash flows to support the recoverability of the assets have been established. Otherwise, the applicable portion of the payments areis expensed. We amortize these intangible assets based on the underlying pattern of economic benefit, which may result in an amortization method other than straight-line. In the aerospace industry, amortization based on the pattern of economic benefit generally results in lower amortization expense during the development period with amortization expense increasing as programs enter full production and aftermarket cycles. If a pattern of economic benefit cannot be reliably determined, a straight-line amortization method is used. We classify amortization of such payments as a reduction of sales. The collaboration intangible assets are amortized based upon the pattern of economic benefits as represented by the underlying cash flows.
Amortization of intangible assets for the quarter and nine months ended September 30, 2018 was $223$225 million and $205$680 million, respectively, compared with $211 million and $626 million for the quarters ended March 31, 2018 and 2017, respectively.same periods of 2017.

Note 2: Revenue Recognition
ASU 2014-09 and its related amendments (collectively, the New Revenue Standard) are effective for reporting periods beginning after December 15, 2017, and interim periods therein. We adopted the New Revenue Standard effective January 1, 2018 and elected the modified retrospective approach. The results for periods before 2018 were not adjusted for the new

standard and the cumulative effect of the change in accounting was recognized through retained earnings at the date of adoption.
Revenue Recognition Accounting Policy Summary. We account for revenue in accordance with Accounting Standards Codification (ASC) Topic 606: Revenue from Contracts with Customers. Under Topic 606, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the customer. Some of our contracts with customers contain a single performance obligation, while other contractsothers contain multiple performance obligations most commonly when contracts spana contract spans multiple phases of the product life-cycle such as development, production, maintenance and support. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. When there are multiple performance obligations within a contract, we allocate the transaction price to each performance obligation based on its standalone selling price.
We consider the contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price, including contractual discounts, contract incentive payments, estimates of award fees, unfunded contract value under U.S. Government contracts, and other sources of variable consideration, when determining the transaction price of each contract. We include variable consideration in the estimated transaction price when there is a basis to reasonably estimate the amount. These estimates are based on historical experience, anticipated performance and our best judgment at the time. We also consider whether our contracts provide customers with significant financing. Generally, our contracts do not contain significant financing.

Point in time revenue recognition. Timing of the satisfaction of performance obligations varies across our businesses due to our diverse product and service mix, customer base, and contractual terms. Performance obligations are satisfied as of a point in time for heating, ventilating, air-conditioning and refrigeration systems, certain alarm and fire detection and suppression systems, and certain aerospace components, engines, and engines components.spare parts. Revenue is recognized when control of the product transfers to the customer, generally upon product shipment.
Over-time revenue recognition. Performance obligations are satisfied over-time if the customer receives the benefits as we perform work, if the customer controls the asset as it is being produced, or if the product being produced for the customer has no alternative use and we have a contractual right to payment. Revenue is recognized for our construction-type and certain production-type contracts on an over-time basis. We recognize revenue on an over-time basis on certain long-term aerospace aftermarket contracts and aftermarket service work; development, fixed price, and other cost reimbursement contracts in our aerospace businesses; and elevator and escalator sales, installation, service, modernization and other construction contracts in our commercial businesses. Commercial businesses service revenue is primarily recognized on a straight-line basis over the contract period. For construction and installation contracts within our commercial businesses and aerospace performance obligations satisfied over time, revenue is recognized using costs incurred to date relative to total estimated costs at completion to measure progress. Incurred costs represent work performed, which correspond with and best depict transfer of control to the customer. Contract costs include labor, materials, and subcontractors' costs, or other direct costs, and where applicable on government and commercial contracts, indirect costs.
For certain of our long-term aftermarket contracts, revenue is recognized over the contract period. In the commercial businesses, revenue is primarily recognized on a straight-line basis over the contract period. In the aerospace businesses, we generally account for such contracts as a series of daily obligations to stand ready to provide product maintenance and aftermarket services. Revenues areRevenue is primarily recognized in proportion to cost as sufficient historical evidence indicates that the cost of performing services under the contract areis incurred on an other than straight-line basis. Aerospace contract modifications are routine and contracts are often modified to account for changes in contract specifications or requirements. Contract modifications that are for goods or services that are not distinct are accounted for as part of the existing contract.
We incur costs for engineering and development of aerospace products directly related to existing or anticipated contracts with customers. Such costs generate or enhance our ability to satisfy our performance obligations under these contracts. We capitalize these costs as contract fulfillment costs to the extent the costs are recoverable from the associated contract margin and subsequently amortize the costs as the original equipment (OEM) products are delivered to the customer. In instances where intellectual property does not transfer to the customer, we defer the customer funding of OEM product engineering and development and recognize revenue when the OEM products are delivered to the customer. Costs to obtain contracts are not material.
Loss provisions on OEM contracts are recognized to the extent that 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 contracts under which losses are recorded upon receipt of the purchase order that obligates us to perform. For existing commitments, anticipated losses on contractual arrangements are recognized in the period in which losses become evident. Products contemplated under contractual arrangements include firm quantities of product 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 arrangement 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.
The New Revenue Standardchanged the revenue recognition practices for a number of revenue streams across our businesses, although the most significant impacts are concentrated in our aerospace units. Several of our businesses which previously accounted for revenue on a point in time basis are now required to use an over-time revenue recognition model when their contracts meet one or more of the mandatory criteria established in the New Revenue Standard. Revenue is now recognized based on a percentage-of-completionan over-time basis using an input method for repair contracts within Otis and UTC Climate, Controls & Security; certain U.S. Government and commercial aerospace equipment contracts; and aerospace aftermarket service work. We measure progress toward completion for these contracts using costs incurred to date relative to total estimated costs at completion. Incurred costs represent work performed, which corresponds with and best depicts the transfer of control to the customer. For these businesses, unrecognized sales related to the satisfied portion of the performance obligations of contracts in process as of the date of adoption of the New Revenue Standard of approximately $220 million were recorded through retained earnings. The ongoing effect on our reported revenues of recordingrecognizing revenue on a percentage-of-completionan over-time basis within these businesses is not expected to be materially different than the previous revenue recognition method.

In addition to the foregoing, our aerospace businesses, in certain cases, also changed the timing of manufacturing cost recognition and certain engineering and development costs. In most circumstances, our commercial aerospace businesses identify the performance obligation as the individual OEM unit; revenuesrevenue and costscost to manufacture each unit are recognized upon OEM unit delivery. Under the prior accounting, the unit of accounting was the contract and early-contract OEM unit costs in excess of the average unit costs expected over the contract were capitalized and amortized over lower-cost units later in the contract. With the adoption of the New Revenue Standard, deferred unit costs in excess of the contract average of $438 million as of January 1, 2018 were eliminated through retained earnings, and as such, will not be amortized into future earnings.
Under the New Revenue Standard, costs incurred for engineering and development of aerospace products under contracts with customers must be capitalized as contract fulfillment costs, to the extent recoverable from the associated contract margin, and subsequently amortized as the OEM products are delivered to the customer. Under prior accounting, we generally expensed costs of engineering and development of aerospace products. The new standard also requires that customer funding of OEM product engineering and development be deferred in instances where economic benefitintellectual property does not transfer to the customer and recognized as revenue when the OEM products are delivered. Engineering and development costs which do not qualify for capitalization as contract fulfillment costs are expensed as incurred. Prior to the New Revenue Standard, any customer funding received for such development efforts was recognized when earned, with the corresponding costs recognized as cost of sales.
With the adoption of the New Revenue Standard, we capitalized engineering and development costs of approximately $700 million as contract fulfillment cost assets through retained earnings as of January 1, 2018. We also established previously recognized customer funding of approximately $850 million as a contract liability through retained earnings as of the adoption date.
We expect the New Revenue Standard will have an immaterial impact on our 2018 net income. Adoption of the New Revenue Standard has resulted in Statement of Operations classification changes between Net Sales, Cost of sales, Research & development, and Other income. The New Revenue Standard also resulted in the establishment of Contract asset and Contract liability balance sheet accounts, and in the reclassification of balances to these new accounts from Accounts receivable;receivable, Inventories and contracts in progress, net, and Accrued liabilities. In addition to the following disclosures, Note 16 provides incremental disclosures required by the New Revenue Standard, including disaggregation of revenue into categories that depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.
The following schedule quantifiesschedules quantify the impact of adopting the New Revenue Standard on the statement of operations for the threequarter and nine months ended March 31,September 30, 2018. The effect of the new standard represents the increase (decrease) in the line item based on the adoption of the New Revenue Standard.

The New Revenue Standard resulted in an increase to Product and Service sales and Cost of products and services sold primarily due to the change to a percentage-of-completionan over-time basis using an input method revenue model for certain U.S Government and commercial aerospace equipment contracts, and aerospace aftermarket service work at Pratt & Whitney and UTC Aerospace Systems. The New Revenue Standard also resulted in an increase in Cost of products sold during the nine months ended September 30, 2018 related to the timing of manufacturing cost recognition on early-contract OEM units sold duringrecognition. During the quarter with costsended September 30, 2018, Cost of products sold were lower under the New Revenue Standard due to a change in excess of the contract average unit costs recorded through Cost of products sold.during the quarter.
The lower amounts of research and development expense recognized under the New Revenue Standard reflect the capitalization of costs of engineering and development of aerospace products as contract fulfillment costs under contracts with customers.

The decrease in Retained earnings of $472$412 million in the table above reflects $480 million of adjustments to the balance sheet as of January 1, 2018, resulting from the adoption of the New Revenue Standard partially offset by $68 million higher reported net income under the new revenue standard.New Revenue Standard during 2018. The declines in Accounts receivable, net, Inventories, Other assets, current, and Intangible assets, net, reflect reclassifications to contract assets, and specifically for Inventories, earlier recognition of costs of products sold for contracts requiring an over-time method of revenue recognition. The increase in Other assets reflects the establishment of non-current contract assets and contract fulfillment cost assets.
The decline in accrued liabilities is primarily due to the reclassification of payments from customers in advance of work performed as contract liabilities. The Other long term liabilities increase primarily reflects the establishment of non-current contract liabilities for certain customer funding of OEM product engineering and development, which will be recognized as revenue when the OEM products are delivered to the customer.

Contract Assets and Liabilities. Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. Total contract assets and contract liabilities as of March 31,September 30, 2018 are as follows:

Under the New Revenue Standard, during the quarternine months ended March 31,September 30, 2018, net contract liabilities increased to $6,531$5,979 million. This reflects the establishment of $6,365 million of net contract liabilities upon the adoption, and $7,031$21,093 million of advance payments from customers and reclassifications of contract assets to receivables upon billing during the period. These increases were partially offset by the liquidation of beginning of period contract liabilities of $1,207$1,978 million as a result of revenue recognition. These increases were also offsetrecognition, and by $5,676$19,499 million of revenue recognition within the period,period. The remaining change is primarily attributable to the impact of foreign currency exchange rate changes on the balance of contract assets and other less significant changes.liabilities offset by net contract liabilities acquired through business combinations.
Remaining performance obligations ("RPO") are the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. As of March 31,September 30, 2018, our total RPO are $99.8is $106.8 billion. Of this total, we expect approximately 40%42% will be recognized as sales over the following 24 months.

The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock appreciation rights and stock options, when the average market price of the common stock is lower than the exercise price of the related stock awards during the period because the effect would be anti-dilutive. In addition, the computation of diluted earnings per share excludes the effect of the potential exercise of stock awards when the awards’ assumed proceeds exceed the average market price of the common shares during the period. For the quartersquarter and nine months ended March 31,September 30, 2018, the number of stock awards excluded from the computation was approximately 5.0 million and 5.2 million, respectively. For the quarter and nine months ended September 30, 2017, the number of stock awards excluded from the computation was approximately 4.35.8 million and 12.26.4 million, respectively.

Prior to the adoption of the New Revenue Standard, within our commercial aerospace business, inventory costs attributable to new engine offerings were recognized based on the average cost per unit expected over the life of each contract using the units-of-delivery method of percentage of completion accounting. Under this method, costs of initial engine deliveries in excess of the projected contract per unit average cost were capitalized and these capitalized amounts were subsequently expensed as additional engines arewere delivered for engines with costs below the projected contract per unit average cost over the life of the contract. As of December 31, 2017, inventory included $438 million of such capitalized amounts. Upon adoption of the New Revenue Standard, these amounts are no longer included in inventory. In addition, amounts previously reported as Contracts in progress have been reclassified as contract assets in accordance with the New Revenue Standard.

At March 31,September 30, 2018,, we had revolving credit agreements with various banks permitting aggregate borrowings of up to $4.35$4.35 billion,, pursuant to a $2.20$2.20 billion revolving credit agreement and a $2.15$2.15 billion multicurrency revolving credit agreement, both of which expire in August 2021. As of March 31,September 30, 2018, there were no borrowings under either of these 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 March 31,September 30, 2018,, our maximum commercial paper borrowing limit was $4.35 billion. Commercial paper borrowings at March 31,September 30, 2018 include approximately €750 million ($930881 million) of euro-denominated commercial paper. We use our commercial paper borrowings for general corporate purposes, including the funding of potential acquisitions, discretionary pension contributions, debt refinancing, dividend payments and repurchases of our common stock. The need for commercial paper borrowings arises when the use of domestic cash for general corporate purposes exceeds the sum of domestic cash generation and foreign cash repatriated to the U.S.
On August 16, 2018, we issued $1.0 billion aggregate principal amount of 3.350% notes due 2021, $2.25 billion aggregate principal amount of 3.650% notes due 2023, $1.5 billion aggregate principal amount of 3.950% notes due 2025, $3.0 billion aggregate principal amount of 4.125% notes due 2028, $750 million aggregate principal amount of 4.450% notes due 2038, $1.75 billion aggregate principal amount of 4.625% notes due 2048, and $750 million aggregate principal amount of floating rate notes due 2021. The net proceeds received from the issuance of the notes due 2021, notes due 2023, notes due 2025, notes due 2028, notes due 2038 and the floating rate notes due 2021 are specifically designated to finance payment obligations with respect to the cash consideration and related fees, expenses and other amounts in connection with the acquisition of Rockwell Collins. If either the acquisition of Rockwell Collins does not occur on or before July 15, 2019 or we notify the trustee that we will not pursue the acquisition of Rockwell Collins, we will be required to redeem the mandatorily redeemable notes then outstanding at a redemption price equal to 101% of the principal amount of such notes plus accrued and unpaid interest (the special mandatory redemption).

We expect to use the proceeds of the notes due 2048 for general corporate purposes which may include the repayment of debt, including outstanding commercial paper. The notes due 2048 are not subject to the special mandatory redemption.
On May 18, 2018, we issued €750 million aggregate principal amount of 1.150% notes due 2024, €500 million aggregate principal amount of 2.150% notes maturing 2030 and €750 million aggregate principal amount of floating rate notes maturing 2020. The net proceeds received from these debt issuances were used for general corporate purposes.
On May 4, 2018, we repaid at maturity approximately $1.1 billion aggregate principal amount of 1.778% junior subordinated notes.
On February 1, 2018, we repaid at maturity the $99 million 6.80% notes due in 2018 and on February 22, 2018, we repaid at maturity the €750 million EURIBOR plus 0.80% floating rate notes due in 2018.notes.
In connection with the merger agreement with Rockwell Collins announced on September 4, 2017, we have entered into a $6.5 billion 364-day unsecured bridge loan credit agreement that would behave been funded only to the extent certain anticipated debt issuances arewere not completed prior to the completion of the merger. This unsecured bridge loan credit agreement was terminated on August 16, 2018 upon issuance of the $11 billion of aggregate principal notes described above. See Note 1 for additional discussion.

We have an existing universal shelf registration statement filed with the Securities and Exchange Commission (SEC) for an indeterminate amount of equity and debt securities for future issuances, subject to our internal limitations on the amount of equity and debt to be issued under this shelf registration statement.
Note 6: Income Taxes
On December 22, 2017, Public Law 115-97 “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” was enacted. This law is commonly referred to as the Tax Cuts and Jobs Act of 2017 (TCJA). In accordance with Staff Accounting Bulletin 118 (SAB 118) issued on December 22, 2017, the U.S. income tax amounts recorded attributable to the TCJA’s deemed repatriation provision, the revaluation of U.S. deferred taxes and the tax consequences relating to states with current conformity to the Internal Revenue Code are provisional amounts. Due to the enactment date and tax complexities of the TCJA, the Company has not completed its accounting related to these items.
Prior to enactment of the TCJA, with few exceptions, U.S. income taxes had not been provided on undistributed earnings of UTC's international subsidiaries as the Company had intended to reinvest such earnings permanently outside the U.S. or to repatriate such earnings only when it was tax effective to do so. The Company continues to evaluate the impact of the TCJA on its existing accounting position related to the undistributed earnings. Due to the inherent complexities in determining any incremental U.S. Federal and State taxes and the non-U.S. taxes that may be due if all of these earnings were remitted to the U.S. and as provided for by SAB 118 this evaluation has not yet been completed and no provisional amount has been recorded in regard to the undistributed amounts. After completing its evaluation, the Company will accrue any additional taxes due on previously undistributed earnings to be distributed in the future.
The Company will continue to accumulate and refine the relevant data and computational elements needed to finalize its accounting for the effects of the TCJA by December 22, 2018.

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, Mexico, Netherlands, Poland, Singapore, South Korea, Spain, Switzerland, 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 2006.
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. It is reasonably possible that a net reduction within the range of $90$40 million to $500$610 million of unrecognized tax benefits may occur within the next 12 months as a result of additional worldwide uncertain tax positions, the closure of tax statutes, or the revaluation of current uncertain tax positions arising from the issuance of legislation, regulatory or other guidance or developments in examinations, in appeals, or in the courts. The range of potential change includes provisional amounts related to the TCJA based on currently available information. See Note 15, 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.
During the quarter, theThe Examination Division of the Internal Revenue Service commenced audit field work for UTC’s 2016 tax year, combining it with the previously commenced audit of tax years 2014 and 2015. The combined audit ofis currently auditing UTC tax years 2014, 2015 and 2016, and the audit is expected to continue beyondconclude within the next 12 months.

Note 7: Employee Benefit Plans
Pension and Postretirement Plans. We sponsor both funded and unfunded domestic and foreign defined pension and other postretirement benefit plans, and defined contribution plans.
In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires an employer to report the service cost component of net periodic pension benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period, with other cost components presented separately from the service cost component and outside of income from operations. This ASU also allows only the service cost component of net periodic pension benefit cost to be eligible for capitalization when applicable. This ASU was effective for years beginning after December 15, 2017. The Company adopted this standard on January 1, 2018 applying the presentation requirements retrospectively. We elected to apply the practical expedient, which allows us to reclassify amounts disclosed previously in the employee benefit plans note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. Provisions related to presentation of the service cost component eligibility for capitalization were applied prospectively.
The effect of the retrospective presentation change related to the net periodic benefit cost of our defined benefit pension and postretirement plans on our condensed consolidated statement of operations was as follows (in millions):follows:

As approved in 2016, effective January 1, 2017, a voluntary lump-sum option is available for the frozen final average earnings benefits of certain U.S. salaried employees upon termination of employment after 2016. This option provides participants with the choice of electing to receive a lump-sum payment in lieu of receiving a future monthly pension benefit. This plan change reduced the projected benefit obligation by $170 million as of December 31, 2016.

2016 and Prior Actions. During the quarternine months ended March 31,September 30, 2018,, we recorded net pre-tax restructuring costs totaling $6$13 million for restructuring actions initiated in 2016 and prior. As of March 31,September 30, 2018, we have approximately $10883 million of accrual balances remaining related to 2016 and prior actions.
Note 9: Financial Instruments
We enter into derivative instruments primarily for risk management purposes, 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 $20.7$20.0 billion and $19.1 billion at March 31,September 30, 2018 and December 31, 2017, respectively.

The following table summarizes the fair value and presentation in the Condensed Consolidated Balance Sheets for derivative instruments as of March 31,September 30, 2018 and December 31, 2017:

The effect of cash flow hedging relationships on accumulated other comprehensive income for the quartersquarter and nine months ended March 31,September 30, 2018 and 2017 are presented in the table below. The amounts of gain or (loss) are attributable to foreign exchange contract activity and are recorded as a component of Product sales when reclassified from accumulated other comprehensive income.

The table above reflects the effect of cash flow hedging relationships on the Condensed Consolidated Statements of Operations for the quartersquarter and nine months ended March 31,September 30, 2018 and 2017. The Company utilizes the critical terms match method in assessing derivatives for hedge effectiveness. Accordingly, the hedged items and derivatives designated as hedging instruments are highly effective.
As discussed in Note 5, weWe have approximately €2.95€4.95 billion of euro-denominated long-term debt and €750 million of euro-denominated commercial paper borrowings outstanding, which qualify as a net investment hedge against our investments in European businesses. As of March 31,September 30, 2018, the net investment hedge is deemed to be effective.
Assuming current market conditions continue, a $36$10 million pre-tax gain is expected to be reclassified from Accumulated other comprehensive loss into Product sales to reflect the fixed prices obtained from foreign exchange hedging within the next 12 months. At March 31,September 30, 2018, all derivative contracts accounted for as cash flow hedges will mature by AprilOctober 2022.
The effect of derivatives not designated as hedging instruments that is included below within Other income, net, on the Condensed Consolidated Statement of Operations was as follows:

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 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 March 31,September 30, 2018,, there were no significant transfers in or out of Level 1 and Level 2.
As of March 31,September 30, 2018, there has not been any significant impact to the fair value of our derivative liabilities due to our own credit risk. Similarly, there has not been any significant adverse impact to our derivative assets based on our evaluation of our counterparties' credit risks.

The following table provides carrying amounts and fair values of financial instruments that are not carried at fair value in our Condensed Consolidated Balance Sheet at March 31,September 30, 2018 and December 31, 2017:

We had commercial aerospace financing and other contractual commitments totaling approximately $15.1 billion and $15.3 billion as of March 31,September 30, 2018 and December 31, 2017, respectively, related to commercial aircraft and certain contractual rights to provide product on new aircraft platforms. Risks associated withAssociated risks on these commitments from changes in interest rates on these commitments are mitigated because interest rates are variable during the commitment term and are set at the date of funding based on current market conditions, the fair value of the underlying collateral and the credit worthiness of the customers. As a result, the fair value of these financings is expected to equal the amounts funded.
Note 11: Long-Term Financing Receivables
Our long-term financing receivables primarily represent balances related to our aerospace businesses, such as long-term trade accounts receivable, notes receivable, and leases receivable. We also have other long-term receivables related to our commercial businesses; however, both the individual and aggregate amounts of those other receivables are not significant.
Prior to the adoption of the New Revenue Standard, long-term trade accounts receivable, including unbilled receivables related to long-term aftermarket contracts, were principally amounts arising from the sale of goods and the delivery of services with a contract maturity date or realization period of greater than one year and were recognized as "Other assets" in our Condensed Consolidated Balance Sheet. With the adoption of the New Revenue Standard, these unbilled receivables are classified as non-current contract assets and are recognized as "Other assets" in our Condensed Consolidated Balance Sheet. Notes and leases receivable represent notes and lease receivables other than receivables related to operating leases, and are recognized as "Customer financing assets" in our Condensed Consolidated Balance Sheet. The following table summarizes the balance by class of aerospace business related long-term receivables as of March 31,September 30, 2018 and December 31, 2017.

Customer credit ratings range from customers with an extremely strong capacity to meet financial obligations to customers whose uncollateralized receivables are 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. The decrease in Long-term trade accounts receivable from December 31, 2017 is primarily driven by the reclassification of unbilled receivables related to long-term aftermarket contracts to contract assets in accordance with the New Revenue Standard as described above. Based upon the customer credit ratings, approximately $140 million and $170 million of our total long-term receivables were considered to bear high credit risk as of March 31,September 30, 2018 and December 31, 2017, respectively.
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 $18 million and $17 million as of March 31,September 30, 2018 and December 31, 2017, are individually evaluated for impairment. At March 31,September 30, 2018 and December 31, 2017, we did not have any significant balances that are considered to be delinquent, on non-accrual status, past due 90 days or more, or are considered to be unrecoverable.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU modifies how entities measure equity investments and present changes in the fair value of financial liabilities. Upon adoption, investments that do not result in consolidation and are not accounted for under the equity method generally must be carried at fair value, with changes in fair value recognized in net income. We had approximately $5 million of unrealized gains on these securities recorded in Accumulated other comprehensive loss in our Consolidated Balance Sheet as of December 31, 2017. We adopted this standard effective January 1, 2018, with these amounts recorded directly to retained earnings as of that date.
Amounts reclassified that relate to our defined benefit pension and postretirement plans include the amortization of prior service costs and actuarial net losses recognized during each period presented. These costs are recorded as components of net periodic pension cost for each period presented (see Note 7 for additional details).
Amounts reclassified that relate to unrealized gains (losses) on available-for-sale securities, pre-tax includes approximately $500 million of previously unrealized gains reclassified to other income as a result of sales of significant investments in available-for-sale securities in the quarternine months ended March 31,September 30, 2017, including UTC Climate, Controls & Security's sale of investments in Watsco, Inc.
All noncontrolling interests with redemption features, such as put options, that are not solely within our control (redeemable noncontrolling interests) are reported in the mezzanine section of the Condensed Consolidated Balance Sheet, between liabilities and equity, at the greater of redemption value or initial carrying value.

Pratt & Whitney holds a net 61% interest in the IAE International Aero Engines AG (IAE) collaboration with MTU Aero Engines AG (MTU) and Japanese Aero Engines Corporation (JAEC) 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. Additionally, Pratt & Whitney, JAEC and MTU are participants in International Aero Engines, LLC (IAE LLC), whose business purpose is to coordinate the design, development, manufacturing and product support for the PW1100G-JM engine for the Airbus A320neo aircraft and the PW1400G-JM engine for the Irkut MC21 aircraft. Pratt & Whitney holds a 59% net interest and a 59% ownership interest in IAE LLC. IAE and IAE LLC retain limited equity with the primary economics of the programs passed to the participants. As such, we have determined that IAE and IAE LLC are variable interest entities with Pratt & Whitney the primary beneficiary. IAE and IAE LLC have, therefore, been consolidated. The carrying amounts and classification of assets and liabilities for variable interest entities in our Condensed Consolidated Balance Sheet are as follows:

Note 15: Contingent Liabilities
Summarized below are the matters previously described in Note 18 of the Notes to the Consolidated Financial Statements in our 2017 Annual Report, incorporated by reference in our 2017 Form 10-K, updated as applicable.
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.
Environmental. Our operations are subject to environmental regulation by federal, state and local authorities in the United States and authorities with jurisdiction over our foreign operations. As described in Note 1 to the Consolidated Financial Statements in our 2017 Annual Report, we have accrued for the costs of environmental remediation activities, including but not limited to investigatory, remediation, operating and maintenance costs and performance guarantees, and periodically reassess these amounts. We believe that the likelihood of incurring losses materially in excess of amounts accrued is remote. Additional information pertaining to environmental matters is included in Note 1 to the Consolidated Financial Statements in our 2017 Annual Report.
Government. In the ordinary course of business, the Company and its subsidiaries and our properties are subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations and threatened legal actions and proceedings. For example, 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. Such U.S. Government investigations often take years to complete and could result in administrative, civil or criminal liabilities, including repayments, fines, treble and other damages, forfeitures, restitution or penalties, or could lead to suspension or debarment of U.S. Government contracting or of export privileges. For instance, 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 anti-bribery, 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 also reserves the right to debar a contractor from receiving new government contracts for fraudulent, criminal or other seriously improper conduct. The U.S. Government could also 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, including because cost or pricing data we submitted in negotiation of the contract prices or cost accounting practices may not

have conformed to 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 or challenge certain matters. 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.
Cost Accounting Standards Claim
As previously disclosed, in December 2013, a Divisional Administrative Contracting Officer of the United States Defense Contract Management Agency asserted a claim against Pratt & Whitney to recover overpayments of approximately $177 million plus interest (approximately $74.9$80 million through March 31,September 30, 2018). 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 $267$253 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 €118 million (approximately $147$139 million). On August 3, 2012, we filed suit in the local German Tax Court (Berlin-Brandenburg). In March 2016, the local German Tax Court dismissed our suit, and we have appealed this decision to the German Federal Tax Court (FTC). Following a hearing on July 24, 2018, the FTC remanded the matter to the local German Tax Court for further proceedings. In 2015, UTC made tax and interest payments to German tax authorities of €275 million (approximately $300 million) in order to avoid additional interest accruals pending final resolution of this matter. In the meantime, we continue vigorously to litigate this matter.
Asbestos Matters
As previously disclosed, like many other industrial companies, we and our subsidiaries have been named as defendants in lawsuits alleging personal injury as a result of exposure to asbestos integrated into certain of our products or business premises. While we have never manufactured asbestos and no longer incorporate it in any currently-manufactured products, certain of our historical products, like those of many other manufacturers, have contained components incorporating asbestos. A substantial majority of these asbestos-related claims have been dismissed without payment or were covered in full or in part by insurance or other forms of indemnity. Additional cases were litigated and settled without any insurance reimbursement. The amounts involved in asbestos related claims were not material individually or in the aggregate in any year.
Our estimated total liability to resolve all pending and unasserted potential future asbestos claims through 2059 is approximately $343$341 million and is principally recorded in Other long-term liabilities on our Condensed Consolidated Balance Sheet as of March 31,September 30, 2018. This amount is on a pre-tax basis, not discounted, and excludes the Company’s legal fees to defend the asbestos claims (which will continue to be expensed by the Company as they are incurred). In addition, the Company has an insurance recovery receivable for probable asbestos related recoveries of approximately $147$156 million, which is included primarily in Other assets on our Condensed Consolidated Balance Sheet as of March 31,September 30, 2018.
The amounts recorded by UTC for asbestos-related liabilities and insurance recoveries are based on currently available information and assumptions that we believe are reasonable. Our actual liabilities or insurance recoveries could be higher or lower than those recorded if actual results vary significantly from the assumptions. Key variables in these assumptions include the number and type of new claims to be filed each year, the outcomes or resolution of such claims, the average cost of resolution of each new claim, the amount of insurance available, allocation methodologies, the contractual terms with each insurer with whom we have reached settlements, the resolution of coverage issues with other excess insurance carriers with whom we have not yet achieved settlements, and the solvency risk with respect to our insurance carriers. Other factors that may affect our future liability include uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case, legal rulings that may be made by state and federal courts, and the passage of state or federal legislation. At least annually, the Company evaluates all of these factors and, with input from an outside actuarial expert, makes any necessary adjustments to both our estimated asbestos liabilities and insurance recoveries.

Other.
As described in Note 14 of this Form 10-Q and Note 17 to the Consolidated Financial Statements in our 2017 Annual Report, 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 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.
In the ordinary course of business, the Company and its subsidiaries are also routinely defendants in, parties to or otherwise subject to many pending and threatened legal actions, claims, disputes and proceedings. These matters are often based on alleged violations of contract, product liability, warranty, regulatory, environmental, health and safety, employment, intellectual property, tax and other laws. In some instances, claims for substantial monetary damages are asserted against the Company and its subsidiaries and could result in fines, penalties, compensatory or treble damages or non-monetary relief. We

do not believe that these matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition.
Note 16: Segment Financial Data
Our operations are classified into four principal segments: Otis, UTC Climate, Controls & Security, Pratt & Whitney, and UTC Aerospace Systems. The segments are generally based on the management structure of the businesses and the grouping of similar operating companies, where each management organization has general operating autonomy over diversified products and services. As discussed in Note 7, 2017 amounts have been recastedrecast based on the adoption of ASU 2017-07.

Note 17: Accounting Pronouncements
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Condensed Consolidated Statement of Operations. In addition, this standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as financing. If the lessor doesn’t convey risks and rewards or control, the lease is treated as operating.
ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capitalIn July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases. This ASU makes various targeted amendments to the leasing standard and operating leases and lessors for sales-type, direct financing, and operating leases existing at, or entered into after, the beginningwe are evaluating this ASU in connection with adoption of the earliest comparative period presentedstandard. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements. This standard allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the financial statements, with certain practical expedients available.period of adoption. We will be adopting this alternative transition method when adopting the new leasing standard as of January 1, 2019. We expect that upon adoption of these standards, we will recognize ROU assets and lease liabilities and that the amounts couldwill be material. We do not expect the ASU 2016-02 to have a material impact on our cash flows or results of operations.
In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). The new standard allows companies to reclassify to retained earnings the stranded tax effects in accumulated other comprehensive income (“AOCI”)(AOCI) from the newly-enacted USU.S. Tax Cuts and Jobs Act. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We expect that upon adoption we will recognize a reclassification from AOCI to retained earnings that could be material, primarily related to pension. We are still evaluating the impact of our pending adoption of the new standard on our consolidated financial statements. However,we expect that upon adoption we will recognize a reclassification from AOCI to retained earnings that could be material. We do not expect this ASU to have a material impact on our cash flows and results of operations. 
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The new standard includes updates to the disclosure requirements for fair value measurements including several additions, deletions and modifications to the disclosure requirements. The provisions of this ASU are effective for years beginning after December 15, 2019, with early adoption permitted. We are currently evaluating the impact of this ASU.


In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. The new standard includes updates to the disclosure requirements for defined benefit plans including several additions, deletions and modifications to the disclosure requirements. The provisions of this ASU are effective for years beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the impact of this ASU.
In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The new standard provides updated guidance surrounding implementation costs associated with cloud computing arrangements that are service contracts. The provisions of this ASU are effective for years beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the impact of this ASU.

With respect to the unaudited condensed consolidated financial information of UTC for the quartersquarter and nine months ended March 31,September 30, 2018 and 2017, PricewaterhouseCoopers LLP (PricewaterhouseCoopers) reported that it has applied limited procedures in accordance with professional standards for a review of such information. However, its report dated April 27,October 26, 2018, appearing below, states that the firm did not audit and does not express an opinion on that unaudited condensed consolidated financial information. PricewaterhouseCoopers has not carried out any significant or additional audit tests beyond those that would have been necessary if their report had not been included. Accordingly, the degree of reliance on its report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers is not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended (the Act) for its report on the unaudited condensed consolidated financial information because that report is not a "report" or a "part" of a registration statement prepared or certified by PricewaterhouseCoopers within the meaning of Sections 7 and 11 of the Act.



Report of Independent Registered Public Accounting Firm

To the Shareowners and Board of Directors of United Technologies Corporation

Results of Review of Financial Information

We have reviewed the accompanying condensed consolidated balance sheet of United Technologies Corporation and its subsidiaries as of March 31,September 30, 2018, and the related condensed consolidated statements of operations and of comprehensive income for the three-month and nine-month periods ended September 30, 2018 and 2017 and the condensed consolidated statement of cash flows for the three-monthnine-month periods ended March 31,September 30, 2018 and 2017, including the related notes (collectively referred to as the “interim financial information”). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of the Corporation as of December 31, 2017, and the related consolidated statements of operations, of comprehensive income, of changes in equity and of cash flows for the year then ended (not presented herein), and in our report dated February 8, 2018, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2017 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Corporation’s management.

Item 2.Management's Discussion and Analysis of Financial Condition and Results of Operations
BUSINESS OVERVIEW
We are a global provider of high technology products and services to the building systems and aerospace industries. Our operations for the periods presented herein are classified into four principal business segments: Otis, UTC Climate, Controls & Security, Pratt & Whitney, and UTC Aerospace Systems. Otis and UTC Climate, Controls & Security are referred to as the "commercial businesses," while Pratt & Whitney and UTC Aerospace Systems are referred to as the "aerospace businesses."
The current status of significant factors affecting our business environment in 2018 is discussed below. For additional discussion, refer to the "Business Overview" section in Management's Discussion and Analysis of Financial Condition and Results of Operations in our 2017 Annual Report, which is incorporated by reference in our 2017 Form 10-K.
General
Our worldwide operations can be affected by industrial, economic and political factors on both a regional and global level. To limit the impact of any one industry, or the economy of any single country on our consolidated operating results, our strategy has been, and continues to be, the maintenance of a balanced and diversified portfolio of businesses. Our operations include original equipment manufacturing (OEM) and extensive related aftermarket parts and services in both our commercial and aerospace businesses. Our business mix also reflects the combination of shorter cycles at UTC Climate, Controls & Security and in our commercial aerospace spares businesses, and longer cycles at Otis and in our aerospace OEM and aftermarket maintenance businesses. Our customers are in the public and private sectors, and our businesses reflect an extensive geographic diversification that has evolved with continued globalization.
Our military businesses' sales are affected by U.S. Department of Defense budget and spending levels. Total sales to the U.S. Government were $1.6$1.9 billion and $1.3$1.4 billion for the quarters ended March 31,September 30, 2018 and 2017, 10%11% and 9% of total UTC sales for those periods, respectively. The defense portion of our aerospace business is affected by changes in market demand and the global political environment. Our participation in long-term production, development and developmentsustainment programs for the U.S. Government has and is expected to contribute positively to our results in 2018.
As has been previously disclosed, the Company is continuing to undertake a strategic review of its portfolio of businesses. There can be no assurance as to the outcome of any such process or that any such process will result in a transaction, or if a transaction is undertaken, as to its terms or timing.
Acquisition Activity
Our growth strategy contemplates acquisitions. Our operations and results can be affected by the rate and extent to which appropriate acquisition opportunities are available, acquired businesses are effectively integrated, and anticipated synergies or cost savings are achieved. During the quarternine months ended March 31,September 30, 2018, our investment in business acquisitions was $125$177 million, which primarily reflects an acquisition at Pratt & Whitney. We do not expect to have additional significant acquisition spend, other than the expected acquisition of Rockwell Collins. However, actual acquisition spending may vary depending upon the timing, availability and value of acquisition opportunities.
On September 4, 2017, we announced that we had entered into a merger agreement with Rockwell Collins, under which we agreed to acquire Rockwell Collins. UnderSee Note 1: Acquisitions, Dispositions, Goodwill and Other Intangible Assets for additional discussion. We do not expect to have additional significant acquisition spend, other than the terms of the merger agreement, each Rockwell Collins shareowner will receive $93.33 per share in cash and a fraction of a share of UTC common stock equal to the quotient obtained by dividing $46.67 by the average of the volume-weighted average price per share of UTC common stock on the NYSE on each of the 20 consecutive trading days ending with the trading day immediately prior to the closing date (the “UTC Stock Price”), subject to adjustment based on a two-way collar mechanism as described below (the “Stock Consideration”). The cash and UTC stock payable in exchange for each such sharepending acquisition of Rockwell Collins common stock are collectively the “Merger Consideration.” The fraction of a share of UTC common stock into which each such share of Rockwell Collins common stock will be converted is the “Exchange Ratio.” The Exchange Ratio will be determined basedCollins. However, actual acquisition spending may vary depending upon the UTC Stock Price. If the UTC Stock Price is greater than $107.01 but less than $124.37, the Exchange Ratio will be equal to the quotient of (i) $46.67 divided by (ii) the UTC Stock Price, which, in each case, will result in the Stock Consideration having a value equal to $46.67. If the UTC Stock Price is less than or equal to $107.01 or greater than or equal to $124.37, then a two-way collar mechanism will apply, pursuant to which, (x) if the UTC Stock Price is greater than or equal to $124.37, the Exchange Ratio will be fixed at 0.37525timing, availability and the value of the Stock Consideration will be greater than $46.67, and (y) if the UTC Stock Price is less than or equal to $107.01, the Exchange Ratio will be fixed at 0.43613 and the value of the Stock Consideration will be less than $46.67. On January 11, 2018, the merger was approved by Rockwell Collins' shareowners. We currently expect that the merger will be completed mid-year 2018, subject to customary closing conditions, including the receipt of required regulatory approvals.
We anticipate that approximately $15 billion will be required to pay the aggregate cash portion of the Merger Consideration. We expect to fund the cash portion of the Merger Consideration through debt issuances and cash on hand. We have entered into a $6.5 billion 364-day unsecured bridge loan credit agreement that would be funded only to the extent certain of the anticipated debt issuances are not completed prior to the completion of the merger. Additionally, we expect to assume

approximately $7 billion of Rockwell Collins' outstanding debt upon completion of the merger.acquisition opportunities. To help manage the cash flow and liquidity resulting from the proposedpending acquisition, we have suspended share repurchases, excluding activity relating to our equity award programs and employee savings plans.
Other
Government legislation, policies and regulations can have a negative impact on our worldwide operations. Government regulation of refrigerants and energy efficiency standards, elevator safety codes and fire protection regulations are important to our commercial businesses. Government and market-driven safety and performance regulations, restrictions on aircraft engine noise and emissions, and government procurement practices can impact our aerospace and defense businesses.
Global economic and political conditions, changes in raw material and commodity prices, interest rates, foreign currency exchange rates, energy costs, levels of end market demand in construction, levels of air travel, the financial condition of commercial airlines, and the impact from natural disasters and weather conditions create uncertainties that could impact our earnings outlook for the remainder of 2018. See Part I, Item 1A, "Risk Factors" in our 2017 Form 10-K for further discussion.
CRITICAL ACCOUNTING ESTIMATES
Preparation of our financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, sales and expenses. We believe the most complex and sensitive judgments, because of their significance to the Consolidated Financial Statements, result primarily from the need to make estimates about the effects of

matters that are inherently uncertain. Management's Discussion and Analysis of Financial Condition and Results of Operations and Note 1 to the Consolidated Financial Statements in our 2017 Annual Report, incorporated by reference in our 2017 Form 10-K, describe the significant accounting estimates and policies used in preparation of the Consolidated Financial Statements. Actual results in these areas could differ from management's estimates.
Effective January 1, 2018, we adopted ASU 2014-09 and its related amendments (collectively, the New Revenue Standard) and elected the modified retrospective approach.
Revenue Recognition Accounting Policy Summary. We account for revenue in accordance with Accounting Standards Codification (ASC) Topic 606: Revenue from Contracts with Customers. Under Topic 606, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the customer. Some of our contracts with customers contain a single performance obligation, while other contracts contain multiple performance obligations most commonly when contracts span multiple phases of the product life-cycle such as development, production, maintenance and support. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. When there are multiple performance obligations within a contract, we allocate the transaction price to each performance obligation based on its standalone selling price.
We consider the contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price, including contractual discounts, contract incentive payments, estimates of award fees, and other sources of variable consideration, when determining the transaction price of each contract. We include variable consideration in estimated transaction price when there is a basis to reasonably estimate the amount. These estimates are based on historical experience, anticipated performance and our best judgment at the time. We consider whether our contracts provide customers with significant financing. Generally, our contracts do not contain significant financing.
Point in time revenue recognition. Timing of the satisfaction of performance obligations varies across our businesses due to our diverse product and service mix, customer base, and contractual terms. Performance obligations are satisfied as of a point in time for heating, ventilating, air-conditioning and refrigeration systems, certain alarm and fire detection and suppression systems, and certain aerospace components and engines components. Revenue is recognized when control of the product transfers to the customer, generally upon product shipment.
Over-time revenue recognition. Performance obligations are satisfied over-time if the customer receives the benefits as we perform work, if the customer controls the asset as it is being produced, or if the product being produced for the customer has no alternative use and we have a contractual right to payment. Revenue is recognized for our construction-type and certain production-type contracts on an over-time basis. We recognize revenue on an over-time basis on certain long-term aerospace aftermarket contracts and aftermarket service work; development, fixed price, and other cost reimbursement contracts in our aerospace businesses; and elevator and escalator sales, installation, service, modernization and other construction contracts in our commercial businesses. Commercial businesses service revenue is primarily recognized on a straight-line basis over the contract period. For construction and installation contracts within our commercial businesses and aerospace performance obligations satisfied over time, revenue is recognized using costs incurred to date relative to total estimated costs at completion to measure progress. Incurred costs represent work performed, which correspond with and best depict transfer of control to the

customer. Contract costs include labor, materials, and subcontractors' costs, or other direct costs, and where applicable on government and commercial contracts, indirect costs.
For certain of our long-term aftermarket contracts, revenue is recognized over the contract period. In the commercial businesses, revenue is primarily recognized on a straight-line basis over the contract period. In the aerospace businesses, we generally account for such contracts as a series of daily obligations to stand ready to provide product maintenance and aftermarket services. Revenues are primarily recognized in proportion to cost as sufficient historical evidence indicates that the cost of performing services under the contract are incurred on an other than straight-line basis. Aerospace contract modifications are routine, and contracts are often modified to account for changes in contract specifications or requirements. Contract modifications that are for goods or services that are not distinct are accounted for as part of the existing contract.
We incur costs for engineering and development of aerospace products directly related to existing or anticipated contracts with customers. Such costs generate or enhance our ability to satisfy our performance obligations under these contracts. We capitalize these costs as contract fulfillment costs to the extent the costs are recoverable from the associated contract margin and subsequently amortize the costs as the original equipment (OEM) products are delivered to the customer. In instances where intellectual property does not transfer to the customer, we defer the customer funding of OEM product engineering and development and recognize revenue when the OEM products are delivered to the customer. Costs to obtain contracts are not material.
Loss provisions on OEM contracts are recognized to the extent that 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 contracts under which losses are recorded upon receipt of the purchase order that obligates us to perform. For existing commitments, anticipated losses on contractual arrangements are recognized in the period in which losses become evident. Products contemplated under contractual arrangements include firm quantities of product 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 arrangement 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.

Note 2 of the condensed consolidated financial statements contains further detail regarding the adoption of the New Revenue Standard and its impact on the statement of operations for the threequarter and nine months ended March 31,September 30, 2018 and the balance sheet as of March 31,September 30, 2018. Under the New Revenue Standard, costs incurred for engineering and development of aerospace products under contracts with customers must be capitalized as contract fulfillment costs, to the extent recoverable from the associated contract margin, and subsequently amortized as the OEM products are delivered to the customer. The estimation of contract margin requires management's judgment. Also as described in Note 2, the New Revenue Standard changed the revenue recognition practices for a number of revenue streams across our businesses. Several of our businesses which previously accounted for revenue on a point in time basis are now required to use an over-time revenue recognition model when their contracts meet one or more of the mandatory criteria established in the New Revenue Standard. Revenue is now recognized on an over-time basis using an input method for repair contracts within Otis and UTC Climate, Controls & Security; certain U.S. Government and commercial aerospace equipment contracts; and aerospace aftermarket service work. We measure progress toward completion for these contracts using costs incurred to date relative to total estimated costs at completion. This over-time basis using an input method requires estimates of future revenues and costs over the full term of product and/or service delivery. Incurred costs represent work performed, which correspond with and best depict transfer of control to the customer. Contract costs are incurred over a period of time, which can be several years, and the estimation of these costs requires management's judgment.

The long-term nature of these contracts, the complexity of the products, and the strict safety and performance standards under which they are regulated can affect our ability to estimate costs and margin precisely. As a result, we review our cost estimates on significant contracts on a quarterly basis and for others, at least 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. For further discussion of significant judgments and estimates related to long-term contract accounting, see the Critical Accounting Estimates disclosure in Management's Discussion and Analysis of Financial Condition and Results of Operations in our 2017 Form 10-K.

Research and development spending is subject to the variable nature of program development schedules and, therefore, year-over-year fluctuations in spending levels are expected. The majority of the company-funded spending is incurred by the aerospace businesses. The year-over-year decrease (5%(1%) in company-funded research and development for the quarter ended March 31,September 30, 2018 was driven by UTC Aerospace Systems (4%) reflecting the capitalization of certain development costs in accordance with the New Revenue Standard and lower spending across various programs, and lower spendinga decline at Pratt & Whitney (3%), reflecting lower expenses across various commercial programs partially offset by an increase at UTC Climate, Controls & Security (1%(2%) that was primarily driven byto support the impact of foreign exchange.

The increase in interest expense reflects the impact of the August 16, 2018 issuance of notes representing $11 billion in aggregate principal; the May 4, 2017 issuance of notes representing $4 billion in aggregate principal,principal; and the May 18, 2018 issuance of Euro-denominated notes representing €2 billion in aggregate principal. These increases were partially offset by the favorable impact of using a portion of the net proceeds of that issuance for the repayment at maturity of 1.800%the following: 1.8% notes in June 2017 representing $1.5 billion in aggregate principal; the 6.8% notes in February 2018 representing $99 million of aggregate principal; the Euro-denominated floating rate notes in February 2018 representing €750 million in aggregate principal; and the 1.778% notes in May 2018 representing $1.1 billion of aggregate principal. The average maturity of our long-term debt at March 31,September 30, 2018 is approximately 1211 years.
$9.2 billion of the $11 billion in aggregate principal amount of notes issued on August 16, 2018 is specifically designated to fund the cash consideration in the acquisition of Rockwell Collins and related fees, expenses and other amounts. Therefore, $9.2 billion of the net proceeds from the issuance have been classified as restricted cash as of September 30, 2018. We expect to use the remaining proceeds for general corporate purposes which may include the repayment of debt, including outstanding commercial paper. The increase in interest income for the quarter and nine months ended September 30, 2018 primarily reflects interest earned on higher cash balances.

In accordance with Staff Accounting Bulletin 118 (SAB 118) issued on December 22, 2017, the U.S. income tax amounts recorded attributable to the TCJA’s deemed repatriation provision, the revaluation of U.S. deferred taxes and the tax consequences relating to states with current conformity to the Internal Revenue Code are provisional amounts. Due to the enactment date and tax complexities of the TCJA, the Company has not completed its accounting related to these items.

Prior to enactment of the TCJA, with few exceptions, U.S. income taxes had not been provided on undistributed earnings of UTC's international subsidiaries as the Company had intended to reinvest such earnings permanently outside the U.S. or to repatriate such earnings only when it was tax effective to do so. The Company continues to evaluate the impact of the TCJA on its existing accounting position related to the undistributed earnings. Due to the inherent complexities in determining any

incremental U.S. Federal and State taxes and the non-U.S. taxes that may be due if all of these earnings were remitted to the U.S. and as provided for by SAB 118 this evaluation has not yet been completed and no provisional amount has been recorded in regard to the undistributed amounts. After completing its evaluation, the Company will accrue any additional taxes due on previously undistributed earnings to be distributed in the future.

The Company will continue to accumulate and refine the relevant data and computational elements needed to finalize its accounting for the effects of the TCJA by December 22, 2018.

The decrease in the effective tax rate for the quarter and nine months ended March 31,September 30, 2018 is primarily due to a reduction ofdecrease in the estimated full year forecasted effective tax rate as a result of the enactment of TCJA. In addition, the rate reflects a tax charge of $44 million primarily related to provisional adjustments associated with regulatory guidance issued during the first quarter regarding the deemed repatriation provisions of the TCJA. This is partially offset by the absence of non-cash tax gains associated with certain federal, state and non-US tax year closures due to audit resolutions and the unfavorable tax impactexpiration of applicable statutes of limitations in the March 31, 2017 period related to the gain on the salethird quarter of UTC Climate Control & Security’s investment in Watsco, Inc.
2017.
As shown in the table above, the effective tax rate for the quarternine months ended March 31,September 30, 2018 is 27.6%25.2%; the effective income tax rate for the same period, excluding restructuring, non-operational nonrecurring items, is 25.0%24.1%. We estimateexpect some variability in our full year 2018 annual effective income tax rate to be approximately 25.5%, excluding restructuring, non-operational nonrecurring items and any provisional adjustments related to the TCJA.

Restructuring actions are an essential component of our operating margin improvement efforts and relate to existing and recently acquired operations. Charges generally arise from severance related to workforce reductions, facility exit and lease termination costs associated with the consolidation of field and manufacturing operations and costs to exit legacy programs. We expect restructuring costs in 2018 to be consistent with 2017, including trailing costs related to prior actions associated with our

continuing cost reduction efforts and the integration of acquisitions. We continue to closely monitor the economic environment and may undertake further restructuring actions to keep our cost structure aligned with the demands of the prevailing market conditions.
2018 Actions. During the quarternine months ended March 31,September 30, 2018,, we recorded net pre-tax restructuring charges of $12$97 million relating to ongoing cost reduction actions initiated in 2018. We expect to incur additional restructuring charges of $40$83 million to complete these actions. We are targeting to complete in 2018 and 2019 the majority of the remaining workforce and facility related cost reduction actions initiated in 2018. We expect recurring pre-tax savings in continuing operations to increase to approximately $26$110 million annually over the two-year period subsequent to initiating the actions. Approximately 95%81% of the total expected pre-tax charges will require cash payments, which we have funded and expect to continue to fund with cash generated from operations. During the quarternine months ended March 31,September 30, 2018, we had cash outflows of approximately $4$48 million related to the 2018 actions.
2017 Actions. During the quarternine months ended March 31,September 30, 2018 and 2017, we recorded net pre-tax restructuring charges of $51$76 million and $24$114 million, respectively, for actions initiated in 2017. We expect to incur additional restructuring charges of $103$116 million to complete these actions. We are targeting to complete in 2018 the majority of the remaining workforce and facility related cost reduction actions initiated in 2017. We expect recurring pre-tax savings in continuing operations to increase over the two-year period subsequent to initiating the actions to approximately $207$250 million annually, of which, approximately $43$139 million was realized during the quarternine months ended March 31,September 30, 2018. Approximately 81%77% of the total expected pre-tax charge will require cash payments, which we have and expect to continue to fund with cash generated from operations. During the quarternine months ended March 31,September 30, 2018, we had cash outflows of approximately $39$86 million related to the 2017 actions.
In addition, during the quarternine months ended March 31,September 30, 2018,, we recorded net pre-tax restructuring costs totaling $6$13 million for restructuring actions initiated in 2016 and prior. For additional discussion of restructuring, see Note 8 to the Condensed Consolidated Financial Statements.
Segment Review
Segments are generally based on the management structure of the businesses and the grouping of similar operating companies, where each management organization has general operating autonomy over diversified products and services. Adjustments to reconcile segment reporting to the consolidated results for the quartersquarter and nine months ended March 31,September 30, 2018 and 2017 are included in "Eliminations and other" below,, which also includes certain smaller subsidiaries. We attempt to quantify material cited factors within our discussion of the results of each segment whenever those factors are determinable. However, in some instances, the factors we cite within our segment discussion are based upon input measures or qualitative information that does not lend itself to quantification when discussed in the context of the financial results measured on an output basis and are not, therefore, quantified in the below discussions.
Commercial Businesses
Our commercial businesses generally serve customers in the worldwide commercial and residential property industries, and UTC Climate, Controls & Security also serves customers in the commercial and transport refrigeration industries. Sales in the commercial businesses are influenced by a number of external factors, including fluctuations in residential and commercial construction activity, regulatory changes, interest rates, labor costs, foreign currency exchange rates, customer attrition, raw material and energy costs, credit markets and other global and political factors. UTC Climate, Controls & Security's financial performance can also be influenced by production and utilization of transport equipment and, in the case of its residential business, weather conditions. To ensure adequate supply of products in the distribution channel, UTC Climate, Controls & Security customarily offers its customers incentives to purchase products. The principal incentive program provides reimbursements to distributors for offering promotional pricing on UTC Climate, Controls & Security products. We account for incentive payments made as a reduction to sales.
At constant currency and excluding the effect of acquisitions and divestitures, UTC Climate, Controls & Security equipment orders in the quarter ended March 31,September 30, 2018 increased 10%13% in comparison to the same period of the prior year, driven by increases in transport refrigeration (37%(91%), fire and security products (8%), residential equipment (2%) and residential equipment (24%commercial HVAC (2%). At constant currency, and excluding the impact of the New Revenue Standard, Otis new equipment orders in the quarter were down 4%increased 9% in comparison to the prior year, driven by a decrease inincreased orders in North America (9%(30%) and China (2%(14%), partially offset by a decline in Europe (10%).

Summary performance for each of the commercial businesses for the quarters ended March 31,September 30, 2018 and 2017 was as follows:

Aerospace Businesses
The aerospace businesses serve both commercial and government aerospace customers. Revenue passenger miles (RPMs), U.S. Government military and space spending, and the general economic health of airline carriers are all barometers for our aerospace businesses. Performance in the general aviation sector is closely tied to the overall health of the economy and is positively correlated to corporate profits.
We continue to see growth in a strong commercial airline industry which is benefiting from traffic growth lower airfares, and stronger economic conditions. Airline traffic, as measured by RPMs, grew approximately 6%7% in the first twoeight months of 2018.
Our commercial aftermarket businesses continue to evolve as an increasing proportiona significant portion of our aerospace businesses' customers are covered under Fleet Management Programs (FMPs) at Pratt & Whitney and long-term aftermarket service agreements at UTC Aerospace Systems. FMPs are comprehensive long-term spare part and service agreements with our customers. We expect a continued shift to FMPs and long-term aftermarket service agreements in lieu of transactional spare part sales as new aerospace product offerings enter our customers' fleets under long-term service agreements and legacy fleets
are retired. For the first threenine months of 2018, as compared with 2017, total commercial aerospace aftermarket sales increased 18%13% at Pratt & Whitney and 16%13% at UTC Aerospace Systems.
We record changes in contract estimates using the cumulative catch-up method. Operating profit in the quarter ended March 31,September 30, 2018 included significant net favorable changes in aerospace contract estimates totaling $55 million, primarily reflecting favorable net contract adjustments at Pratt & Whitney. Operating profit for the nine months ended September 30, 2018 included significant net unfavorable changes in aerospace contract estimates totaling $41$28 million, reflecting unfavorable net contract adjustments recorded at both UTC Aerospace Systems and Pratt & Whitney. Operating profit in the quarter and nine months ended September 30, 2017 included significant net unfavorable changes in aerospace contract estimates totaling $21 million and $50 million, respectively, primarily reflecting unfavorable net contract adjustments recorded at Pratt & Whitney and UTC Aerospace Systems. Operating profit in the quarter ended March 31, 2017 included significant net unfavorable changes in aerospace contract estimates of $29 million, primarily representing unfavorable contract adjustments recorded at Pratt & Whitney.
As previously disclosed, Pratt & Whitney's PurePower PW1500G engine models have been selected by Bombardier to power the new CSeries passenger aircraft, which entered into service on July 15, 2016. There have been multi-year delays in the development of the CSeries aircraft. Notwithstanding these delays, Bombardier reports that they have received over 300 orders for the aircraft and that both the CS100 and CS300 aircraft models have been certified and have entered into revenue service.  We have made various investments in support of the production and delivery of our PW1500G engines and systems for the CSeries program, which we currently expect to recover through future deliveries of PW1500G powered CSeries aircraft. On October 16, 2017, Bombardier and Airbus announced an agreement to become partners on the CSeries aircraft program. We will continue to monitor the progress of the program and our ability to recover our investments, which we believe would be strengthened by this partnership.

* For Pratt & Whitney only, the transactional impact of foreign exchange hedging at Pratt & Whitney Canada has been netted against the translational foreign exchange impact for presentation purposes in the above table.table above. For all other segments these foreign exchange transactional impacts are included within the organic/operational caption in their respective tables. Due to its significance to Pratt & Whitney's overall operating results, we believe it is useful to segregate the foreign exchange transactional impact in order to clearly identify the underlying financial performance.

Eliminations and other reflects the elimination of sales, other income and operating profit transacted between segments, as well as the operating results of certain smaller businesses. The year-over-year decreaseincrease in sales eliminations for the quarter and nine months ended March 31,September 30, 2018, as compared to the same periodperiods of 2017, reflects an increase in the amount of inter-segment eliminations, principally between our aerospace businesses.

We assess our liquidity in terms of our ability to generate cash to fund our operating, investing and financing activities. Our principal source of liquidity is operating cash flows from continuing operations. For 2018, we expect cash flows from continuing operations, net of capital expenditures, to approximate $4.5 billion to $5.0 billion. In addition to operating cash flows, other significant factors that affect our overall management of liquidity include: capital expenditures, customer financing requirements, investments in businesses, dividends, common stock repurchases, pension funding, access to the commercial paper markets, adequacy of available bank lines of credit, redemptions of debt, and the ability to attract long-term capital at satisfactory terms.
At March 31,September 30, 2018, we had cash and cash equivalents of $7,667$13,799 million, of which approximately 51%31% was held by UTC's foreign subsidiaries. We manage our worldwide cash requirements by reviewing available funds among the many subsidiaries through which we conduct our business and the cost effectiveness with which those funds can be accessed. As previously discussed, on December 22, 2017, the TCJA was enacted. Prior to enactment of the TCJA, with few exceptions, U.S. income taxes had not been provided on undistributed earnings of UTC's international subsidiaries as the Company had intended to reinvest such earnings permanently outside the U.S. or to repatriate such earnings only when it was tax effective to do so. The Company continues to evaluate the impact of the TCJA on its existing accounting position related to the undistributed earnings. Due to the inherent complexities in determining any incremental U.S. Federal and State taxes and the non-U.S. taxes that may be due if all of these earnings were remitted to the U.S., and in accordance withas provided for by SAB 118, this evaluation has not been completed and no provisional amount has been recorded in regard to the undistributed amounts. After completing its evaluation, the Company will accrue any additional taxes due on previously undistributed earnings to be distributed in the future.
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 March 31,September 30, 2018 and December 31, 2017, the amount of such restricted cash was approximately $37 million$9.2 billion and $33 million, respectively.

Restricted cash increased by $9.2 billion in the quarter ended September 30, 2018 due to the $11 billion of aggregate notes issued during the quarter of which $9.2 billion of net proceeds were specifically designated for the pending acquisition of Rockwell Collins, Inc.
Historically, our strong debt ratings and financial position have enabled us to issue long-term debt at favorable market rates. Our ability to obtain debt financing at comparable risk-based interest rates is partly a function of our existing debt-to-total-capitalization level as well as our credit standing. Our debt-to-total-capitalization of 46%54% at MarchSeptember 30, 2018, increased 700 basis points from December 31, 2018, remained consistent with2017 primarily due to the prior year.issuance of $11 billion of aggregate notes for the pending Rockwell acquisition. We use our commercial paper borrowings for general corporate purposes, including the funding of potential acquisitions, discretionary pension contributions, debt refinancing, dividend payments and repurchases of our common stock. The need for commercial paper borrowingsborrowing arises when the use of domestic cash for general corporate purposes exceeds the sum of domestic cash generation and foreign cash repatriated to the U.S.
At March 31,September 30, 2018, 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 August 2021. As of March 31,September 30, 2018, there were no borrowings under 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 March 31,September 30, 2018, our maximum commercial paper borrowing limit was $4.35 billion.

Commercial paper borrowings at March 31,September 30, 2018 include approximately €750 million ($930881 million) of euro-denominated commercial paper.
On August 16, 2018, we issued $1.0 billion aggregate principal amount of 3.350% notes due 2021, $2.25 billion aggregate principal amount of 3.650% notes due 2023, $1.5 billion aggregate principle amount of 3.950% notes due 2025, $3.0 billion aggregate principal amount of 4.125% notes due 2028, $750 million aggregate principal amount of 4.450% notes due 2038, $1.75 billion aggregate principal amount of 4.625% notes due 2048, and $750 million aggregate principal amount of floating rate notes due 2021. We expect to use the net proceeds received from the issuance of the notes due 2021, notes due 2023, notes due 2025, notes due 2028, notes due 2038 and the floating rate notes due 2021 to partially finance payment obligations with respect to the cash consideration and related fees, expenses and other amounts in connection with the acquisition of Rockwell Collins, Inc. We expect to use the proceeds of the notes due 2048 for general corporate purposes and/or the repayment of debt, including outstanding commercial paper.
On May 18, 2018, we issued €750 million aggregate principal amount of 1.150% notes due 2024, €500 million aggregate principal amount of 2.150% notes maturing 2030 and €750 million aggregate principal amount of floating rate notes maturing 2020. The net proceeds received from these debt issuances were used for general corporate purposes.
On May 4, 2018, we repaid at maturity approximately $1.1 billion aggregate principal amount of 1.778% junior subordinated notes.
On February 1, 2018, we repaid at maturity the $99 million 6.80% notes due in 2018 and on February 22, 2018, we repaid at maturity the €750 million EURIBOR plus 0.80% floating rate notes due in 2018.notes.
On November 13, 2017, we issued €750 million aggregate principal amount of floating rate notes due 2019. The net proceeds from this debt issuance were used to fund the repayment of commercial paper and for other general corporate purposes.
On May 4, 2017, we issued $1.0 billion aggregate principal amount of 1.900% notes due 2020, $500 million aggregate principal amount of 2.300% notes due 2022, $800 million aggregate principal amount of 2.800% notes due 2024, $1.1 billion aggregate principal amount of 3.125% notes due 2027 and $600 million aggregate principal amount of 4.050% notes due 2047. The net proceeds received from these debt issuances were used to fund the repayment at maturity of our 1.800% notes due 2017, representing $1.5 billion in aggregate principal and other general corporate purposes.
Within the Business Overview of Management's Discussion and Analysis, we have described the pending acquisition of Rockwell Collins. The purchase consideration will be a combination of UTC shares and cash. We anticipate that approximately $15 billion will be required to pay the aggregate cash portion of the Merger Consideration. We expect to fund the cash portion of the Merger Consideration through debt issuances andwhich will be funded by cash on hand. Additionally, we have entered into a $6.5 billion 364-day unsecured bridge loan credit agreement that would be funded only to the extent certain anticipated debt issuances are not completed prior to the completion of the merger. We expect to assume approximately $7 billion of Rockwell Collins’ outstanding debt. To help manage the cash flow and liquidity impact resulting from the proposedpending acquisition, we have suspended share repurchases, excluding activity relating to our equity award programs and employee savings plans. As we continue to assess the impacts of the TCJA, future opportunities for repatriation of our non-U.S. earnings, and accelerated de-leveraging, we may consider, in addition to investments in our operations, limited additional share repurchases to offset the effects of dilution related to our stock-based compensation programs. We have repatriated $3.8to the U.S. $5.2 billion of overseas cash forduring the quarternine months ended March 31,September 30, 2018. Available cash on hand will be used to reduce the debt funding requirements for the transaction.
We believe our future operating cash flows will be sufficient to meet our future operating cash needs. Further, we continue to have access to the commercial paper markets and our existing credit facilities, and our ability to obtain debt or equity financing, as well as the availability under committed credit lines, provides additional potential sources of liquidity should they be required or appropriate.

Cash generated from operating activities in the quarternine months ended March 31,September 30, 2018 was $540$1,207 million lowerhigher than the same period in 2017. This decrease in cash flows provided by operations is driven by an increase inCash outflows for working capital of $497increased $285 million primarily duein the nine months ended September 30, 2018 over the prior period to support higher top line organic growth. Factoring activity provided an increase in accounts receivable of $872 million and an increase in short term contract assets of $417 million, partially offset by an increase in short term contract liabilities of $652 million. The primary drivers for the growth in

accounts receivable are sales growth and a reduction in factoring activity. The reduced volume of factoring activity resulted in a decrease of approximately $560 million in cash generated from operating activities of approximately $168 million in the quarternine months ended March 31,September 30, 2018, as compared to the prior year. This decreaseincrease in factoring was driven largely by Pratt & Whitney's temporary extension of contractual payment terms with certain commercial aerospace customers. This increase does not reflect the factoring of certain aerospace receivables performed at customer request for which we are compensated by the customer for the extended payment cycle.

In the quarternine months ended March 31,September 30, 2018, cash outflows from working capital were $972 million.$643 million, excluding the adoption impact of the New Revenue Standard. Accounts receivablesreceivable increased $2.4 billion due to an increase in sales volumevolume. Contract assets, current increased $892 million due to costs in excess of billings primarily at Pratt & Whitney driven by military engines, at Otis due to progression on major projects, and at UTC Climate, Controls & Security North American HVAC Residential business and UTC Aerospace Systems and Pratt & Whitney, timing, and a decrease in factoring activity on receivables , primarily at Pratt & Whitney. Current contract assets increased primarily due to progress and spend on fleet maintenance contracts and government contracts at Pratt & Whitney.Building Solution Systems. Inventory increased in the quarter$991 million primarily driven by UTC Climate, Controls & Security seasonal build and an increase in production work in process for the A320 NEOGeared Turbo Fan at Pratt & Whitney, seasonal build in the aerospace businesses.Residential & Commercial HVAC businesses at UTC Climate, Controls & Security, and increases at UTC Aerospace Systems. These increases were partially offset by decreases in Other assets of $262 million primarily driven by a reduction in prepaid taxes, increases in accountsAccounts payable and accrued liabilities of approximately $3.0 billion, driven by the higher inventory purchasing activity and customer advances at Pratt & Whitney, higher direct material purchases at UTC Aerospace Systems, and an increase in accrued interest, as well as an increase in Contract liabilities, current contract liabilitiesof $313 million driven by seasonal advanced billings and progress payments on major contracts and seasonal advanced billings at Otis and the timingOtis.
As part of billings on aftermarket contracts at Pratt & Whitney.
Inour long-term strategy to de-risk our defined benefit pension plans, we made discretionary contributions of approximately $1.9 billion to our domestic defined benefit pension plans in the quarter ended March 31,September 30, 2017. Including the effects of this contribution, cash generated from operating activities of continuing operations in the nine months ended September 30, 2017 was $1,457 million lower than the same period in 2016. Cash outflows for working capital improved by $341 million in the nine months ended September 30, 2017 over the prior year period. In the nine months ended September 30, 2017, inventories increased $654 million,approximately $1.2 billion, primarily in our aerospace businesses supporting an increase in forecasted OEM deliveries and related aftermarket demand, and at UTC Climate, Controls & Security driven primarily driven by seasonal demand in our North American HVAC business and installation projects in process in our refrigeration businesses. These increases were more than offset by increases in accounts payable and accrued liabilities, primarily in the commercial engine business at Pratt & Whitney. Accounts receivable increased primarily in our aerospace businesses, and were partially offset by increased customer advances at Pratt & Whitney and Otis. Factoring activity provided an increase of approximately $500$400 million in cash generated from operating activities of continuing operations in the quarternine months ended March 31,September 30, 2017, as compared to the prior year period. This increase in factoring was driven largely by Pratt & Whitney's temporary extension of contractual payment terms with certain commercial aerospace customers. Increases in accrued liabilities were driven primarily by higher accruals for taxes and interest due to the timing of payments.
The funded status of our defined benefit pension plans is dependent upon many factors, including returns on invested assets, the level of market interest rates and actuarial mortality assumptions. We can contribute cash or UTC shares to our plans at our discretion, subject to applicable regulations. Total cash contributions to our global defined benefit pension plans during the quarternine months ended March 31,September 30, 2018 and 2017 were approximately $37$72 million and $46$2,008 million, respectively. Although our domestic pension plans are approximately 102%104% funded on a projected benefit obligation basis as of March 31,September 30, 2018, and we are not required to make additional contributions through the end of 2028, we may elect to make discretionary contributions in 2018. We expect to make total contributions of approximately $100 million to our global defined benefit pension plans in 2018. Contributions to our global defined benefit pension plans in 2018 are expected to meet or exceed the current funding requirements.

Cash flows used in investing activities of continuing operations for the quarternine months ended March 31,September 30, 2018 and 2017 primarily reflect capital expenditures, cash investments in businesses, cash investments in customer financing assets, investments/dispositions of businesses, payments related to our collaboration intangible assets and contractual rights to provide product on new aircraft platforms, and settlements of derivative contracts. The increase$639 million decrease in cash flows used in investing activities in the quarternine months ended March 31,September 30, 2018 compared to March 31,September 30, 2017 of $837 million primarily relates to the $1 billion in proceeds from the sale of Taylor Company in June 2018 by UTC Climate, Controls & Security and $254 million in receipts from settlements of derivative contracts, partially offset by the absence of $136 million of proceeds for the sale of available for sale securities as of September 30, 2017 and $596 million in net proceeds received of $596 million from UTC Climate, Controls & Security's sale of investments in Watsco, Inc. in the quarter ended March 31, 2017 as well as an increase in customer financing asset of $94 million, and an increase in payment from settlements of derivatives contracts of $108 million.2017.
Capital expenditures for the quarternine months ended March 31,September 30, 2018 ($3371,122 million) primarily relate to investments in production capacity at Pratt & Whitney, new facilities at UTC Climate, Controls & Security, as well as several small projects at UTC Aerospace Systems.Systems, and new facilities and investments in products and information technology at UTC Climate, Controls & Security.
Cash investments in businesses in the quarternine months ended March 31,September 30, 2018 ($125177 million) primarily consisted of an acquisition at Pratt & Whitney. We do not expect to have additional significant acquisition spend, other than the expectedpending acquisition of Rockwell Collins. However, actual acquisition spending may vary depending upon the timing, availability and

appropriate value of acquisition opportunities.

Dispositions of businesses in the nine months ended September 30, 2018 of $1.1 billion primarily relate to the sale of Taylor Company.
Customer financing activities in the nine months ended September 30, 2018 were a net use of cash of $241$453 million, primarily driven by additional Geared Turbofan engines to support customer fleets, and $147 million for the quarter ended March 31, 2018 and 2017, respectively.fleets. While we expect that 2018 customer financing activity will be a net use of funds, actual funding is subject to usage under existing customer financing commitments during the remainder of the year. We may also arrange for third-party investors to assume a portion of our commitments. We had commercial aerospace financing and other contractual commitments of approximately $15.1 billion at March 31,September 30, 2018 related to commercial aircraft and certain contractual rights to provide product on new aircraft platforms, of which up to $0.8 billion$300 million may be required to be disbursed during the remainder of 2018. We had commercial aerospace financing and other contractual commitments of approximately $15.3 billion at December 31, 2017.
During the quarternine months ended March 31,September 30, 2018, our collaboration intangible assets increased by approximately $78$302 million, of which $72 million resulted fromprimarily relates to payments made under our 2012 agreement to acquire Rolls-Royce's collaboration interest in IAE.
As discussed in Note 9 to the Condensed Consolidated Financial Statements, 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 settlement of these derivative instruments resulted in a net cash outflowinflow of approximately $221 million and $113$71 million during the quarternine months ended March 31,September 30, 2018 and 2017, respectively.a net cash outflow of $183 million during the nine months ended September 30, 2017.

Commercial paper borrowings and revolving credit facilities provide short-term liquidity to supplement operating cash flows and are used for general corporate purposes, including the funding of potential acquisitions and repurchases of our stock. We had approximately $0.9$1.4 billion of outstanding commercial paper at March 31,September 30, 2018.
At March 31,September 30, 2018, management had remaining authority to repurchase approximately $2.3$2.2 billion of our common stock under the October 14, 2015 share repurchase program. Under this program, shares may be purchased on the open market, in privately negotiated transactions, under accelerated share repurchase programs, and under plans complying with Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended. We may also reacquire shares outside of the program from time to time in connection with the surrender of shares to cover taxes on vesting of restricted stock and as required under our employee savings plan. We made cash payments of approximately $25$72 million to repurchase approximately 188574 thousand shares of our common stock during the quarternine months ended March 31,September 30, 2018. In connection with the merger agreement with Rockwell Collins announced on September 4, 2017, we have suspended share repurchases, excluding activity required under our equity award programs and employee savings plans. As we continue to assess the impacts of the TCJA, future opportunities for repatriation of our non-U.S. earnings, and accelerated de-leveraging, we may consider, in addition to investments in our operations, limited additional share repurchases to offset the effects of dilution related to our stock-based compensation programs.
We paid dividends on common stock of $0.70 per share in the first, second and third quarter of 2018, totaling approximately $535$1,606 million in the aggregate for the quarternine months ended March 31,September 30, 2018. On February 5,October 10, 2018, the Board of Directors declared a dividend of $0.70$0.735 per share payable MarchDecember 10, 2018 to shareowners of record at the close of business on FebruaryNovember 16, 2018.

We have an existing universal shelf registration statement filed with the SEC for an indeterminate amount of debt and equity securities for future issuance, subject to our internal limitations on the amount of debt to be issued under this shelf registration statement.
Off-Balance Sheet Arrangements and Contractual Obligations
In our 2017 Annual Report, incorporated by reference in our 2017 Form 10-K, we disclosed our off-balance sheet arrangements and contractual obligations. As of March 31,September 30, 2018,, there have been no material changes to these off-balance sheet arrangements and contractual obligations outside the ordinary course of business.

PART II – OTHER INFORMATION

Item 1.    Legal Proceedings

Federal Securities Laws Litigation
Telephone Consumer Protection Act
AsOn January 2, 2018, a purported shareowner filed a second amended complaint in the United States District Court for the Southern District of New York under the federal securities laws against the Company and certain of its current and former executives (Frankfurt-Trust Investment Luxemburg AG v. United Technologies Corporation et al.), which further amends a previously disclosed UTC Fire & Security Americas Corporation, Inc. (UTCFS)complaint that was named as a defendant in numerous putative class actions that were filed on behalfMay 10, 2017. In the second amended complaint, the plaintiff purports to represent a class of purported classesshareowners who purchased the Company’s stock between December 11, 2014 and July 20, 2015. The second amended complaint alleges violations of persons who alleged that third-party entities placed "robocalls" and/or placed calls to numbers listed on the "Do Not Call Registry" on behalf of UTCFS in contraventionSections 10(b) and 20(a) of the Telephone Consumer ProtectionSecurities Exchange Act (TCPA).  In each putative class action suit, plaintiffs sought injunctive reliefof 1934, and monetary damages.  Each violation underRule 10b-5 thereunder, related to alleged false and misleading statements and omissions of material fact made in connection with the TCPA provides for $500Company’s 2015 earnings expectations. On September 28, 2018, the Court granted the defendants’ motion to dismiss the case in statutory damages or upits entirety.  On October 25, 2018, the plaintiff filed a Notice of Appeal to $1,500 for any willful violation.  In August 2016, UTCFS moved for summary judgment in the Northern District of West Virginia, the court in which all of the pending TCPA cases has been consolidated, arguing that the third parties who placed the calls in alleged violation of the TCPA were not acting as UTCFS’ agents and, therefore, UTCFS could not be vicariously liable for those calls under the TCPA.  On December 22, 2016, the district court granted UTCFS’ summary judgment motion and dismissed the claims against UTCFS. The plaintiffs appealed the decision on February 14, 2017. On March 14, 2018, the United States Court of Appeals for the Fourth Circuit affirmed the district court's decision. We believe that this matter is now concluded.Second Circuit.

(UTIO) and IAE for the sale of Pratt & Whitney and IAE engines and aftermarket services, respectively, in China. On April 7, 2014, the SEC notified UTC that it was conducting a formal investigation and issued a subpoena to UTC. The SEC issued a second subpoena on March 9, 2015 seeking documents related to internal allegations of violations of anti-bribery laws from UTC’s aerospace and commercial businesses, including but not limited to Otis businesses in China. On March 7, 2018, the DOJ notified UTC that it had decided to close its investigation of this matter. We have engaged in discussionsIn the third quarter of 2018, UTC reached a final civil administrative resolution with the SEC staffregarding this matter, including a payment to resolve this matter.
