NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
The Condensed Consolidated Financial Statements at March 31, 20182019 and for the quarters ended March 31, 20182019 and 20172018 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 (20172018 Annual Report) incorporated by reference in our Annual Report on Form 10-K for calendar year 20172018 (20172018 Form 10-K).
Note 1: Acquisitions, Dispositions, Goodwill and Other Intangible Assets
Business Acquisitions and Dispositions.Acquisitions. During the three months ended March 31, 2018,2019, our investment in business acquisitions was $125$19 million, and primarilywhich consisted of ansmall acquisitions at Otis.
On November 26, 2018, we completed the acquisition at Pratt & Whitney.
On September 4, 2017, we announced that we had entered into a merger agreement withof Rockwell Collins Inc. (Rockwell Collins)(the "Merger"), under which we agreed to acquire Rockwell Collins.a leader in aviation and high-integrity solutions for commercial and military customers as well as leading-edge avionics, flight controls, aircraft interior and data connectivity solutions. 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 pricespar value $0.01 per share, of UTC common stock on the NYSE on each of the 20 consecutive trading days ending with the trading dayRockwell Collins issued and outstanding immediately prior to the closing date, (the “UTC Stock Price”effective time of the Merger (other than shares held by Rockwell Collins, the Company, Riveter Merger Sub Corp or any of their respective wholly owned subsidiaries) was converted into the right to receive (1) $93.33 in cash, without interest, and (2) 0.37525 shares of Company common stock (together, the “Merger Consideration”), subject to adjustment based on a two-way collar mechanism as described below (the “Stock Consideration”).less any applicable withholding taxes, with cash paid in lieu of fractional shares. The cash and UTC stocktotal aggregate consideration payable in exchange for each such sharethe Merger was $15.5 billion in cash ($14.9 billion net of cash acquired) and 62.2 million shares of Company common stock. In addition, $7.8 billion of Rockwell Collins common stockdebt was outstanding at the time of the Merger. This equated to a total enterprise value of $30.6 billion, including the $7.8 billion of Rockwell Collins' outstanding debt.     
(dollars in millions) Amount
Cash consideration paid for Rockwell Collins outstanding common stock & equity awards $15,533
Fair value of UTC common stock issued for Rockwell Collins outstanding common stock & equity awards 7,960
Total consideration transferred $23,493
The cash consideration utilized for the Rockwell Collins acquisition was partially financed through the previously disclosed issuance of $11 billion aggregate principal notes on August 16, 2018 for net proceeds of $10.9 billion. For the remainder of the cash consideration, we utilized repatriated cash and cash equivalents and cash flow generated from operating activities.
Preliminary Allocation of Consideration Transferred to Net Assets Acquired:
The following amounts represent the preliminary determination of the fair value of identifiable assets acquired and liabilities assumed from the Rockwell Collins acquisition. The final determination of the fair value of certain assets and liabilities will be completed up to a one year measurement period from the date of acquisition as required by the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 805, “Business Combinations.” As of March 31, 2019, the valuation studies necessary to determine the fair market value of the assets acquired and liabilities assumed are collectivelypreliminary, including the “Merger Consideration.”validation of the underlying cash flows used to determine the fair value of the identified intangible assets. The fractionsize and breadth of the Rockwell Collins acquisition necessitates use of the one year measurement period to adequately analyze all the factors used in establishing the asset and liability fair values as of the acquisition date, including, but not limited to, intangible assets, inventory, real property, leases, deferred tax liabilities related to the unremitted earnings of foreign subsidiaries, certain reserves and the related tax impacts of any adjustments. Any potential adjustments could be material in relation to the preliminary values presented below:

Total identifiable net assets2,940
Goodwill20,553
Total consideration transferred$23,493
In order to allocate the consideration transferred for Rockwell Collins, the fair values of all identifiable assets and liabilities were established. For accounting and financial reporting purposes, fair value is defined under FASB ASC Topic 820, “Fair Value Measurements and Disclosures” as the price that would be received upon sale of an asset or the amount paid to transfer a shareliability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. Use of different estimates and judgments could yield different results. Fair value adjustments to Rockwell Collins' identified assets and liabilities resulted in an increase in inventory and fixed assets of $282 million and $269 million, respectively. In determining the fair value of identifiable assets acquired and liabilities assumed, a review was conducted for any significant contingent assets or liabilities existing as of the acquisition date. The preliminary assessment did not note any significant contingencies related to existing legal or government action.

The fair values of the customer relationship and related program intangible assets, which include the related aerospace program original equipment (OEM) and aftermarket cash flows, were determined by using an “income approach." Under this approach, the net earnings attributable to the asset or liability being measured are isolated using the discounted projected net cash flows. These projected cash flows are isolated from the projected cash flows of the combined asset group over the remaining economic life of the intangible asset or liability being measured. Both the amount and the duration of the cash flows are considered from a market participant perspective. Our estimates of market participant net cash flows considered historical and projected pricing, remaining developmental effort, operational performance, including company specific synergies, aftermarket retention, product life cycles, material and labor pricing, and other relevant customer, contractual and market factors. Where appropriate, the net cash flows are probability-adjusted to reflect the uncertainties associated with the underlying assumptions as well as the risk profile of the net cash flows utilized in the valuation. The probability-adjusted future cash flows are then discounted to present value using an appropriate discount rate. The customer relationship and related program intangible assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of the underlying programs of 10 to 20 years. The developed technology intangible asset is being amortized over the economic pattern of benefit. The fair value of the tradename intangible assets were determined utilizing the relief from royalty method which is a form of the income approach. Under this method, a royalty rate based on observed market royalties is applied to projected revenue supporting the tradename and discounted to present value using an appropriate discount rate.  The tradename intangible assets have been determined to have an indefinite life. The Intangible assets included above consist of the following:

We also identified customer contractual obligations on certain contracts with economic returns that are lower than could be realized in market transactions as of the acquisition date. We measured these liabilities under the measurement provisions of FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” which is based on the price to transfer the obligation to a market participant at the measurement date, assuming that the liability will remain outstanding in the marketplace. Based on the estimated net cash outflows of the programs plus a reasonable contracting profit margin required to transfer the contracts to market participants, we recorded assumed liabilities of approximately $1,020 million. These liabilities will be liquidated in accordance with the underlying pattern of obligations, as reflected by the expenses incurred on the contracts. Total consumption of the contractual obligation for the next five years is expected to be as follows: $145 million in 2019, $133 million in 2020, $131 million in 2021, $125 million in 2022, and $118 million in 2023.
Acquisition-Related Costs:
Acquisition-related costs have been expensed as incurred. In the quarters ended March 31, 2019 and 2018, approximately $9 million and $30 million, respectively, of transaction and integration costs have been incurred. These costs were recorded in Selling, general and administrative expenses within the Condensed Consolidated Statement of Operations.
Supplemental Pro-Forma Data:
Rockwell Collins' results of operations have been included in UTC’s financial statements for the period subsequent to the completion of the acquisition on November 26, 2018. Rockwell Collins contributed sales of approximately $2.3 billion and operating profit of approximately $264 million for the quarter ended March 31, 2019. The following unaudited supplemental pro-forma data presents consolidated information as if the acquisition had been completed on January 1, 2017. The pro-forma results were calculated by combining the results of UTC common stock into which each such sharewith the stand-alone results of Rockwell Collins common stock will be converted isfor the “Exchange Ratio.” pre-acquisition periods, which were adjusted to account for certain costs that would have been incurred during this pre-acquisition period:

Further, the Stock Consideration having a value equalpro-forma data should not be considered indicative of the results that would have occurred if the acquisition and related financing had been consummated on January 1, 2017, nor are they indicative of future results.

Dispositions. Cash inflows related to $46.67. Ifdispositions during the UTC Stock Price is less than or equalthree months ended March 31, 2019 were $133 million and primarily consisted of the dispositions of businesses held for sale associated with the Rockwell Collins acquisition. In accordance with conditions imposed for regulatory approval of the acquisition, Rockwell Collins was required to $107.01 or greater than or equal to $124.37, then a two-way collar mechanism will apply,dispose of certain businesses. These businesses were held separate from UTC’s and Rockwell Collins' ongoing businesses pursuant to which, (x) if the UTC Stock Price is greater than or equalregulatory requirements. Definitive agreements to $124.37, the Exchange Ratio will be fixed at 0.37525 and the valuesell each 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. Additionally, we havebusinesses were 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 billionUTC's acquisition of Rockwell Collins' outstanding debt uponCollins. The related assets and liabilities of these businesses had been accounted for as held for sale at fair value less cost to sell. As of December 31, 2018, assets held for sale of $175 million were included within Other assets, current and liabilities held for sale of $40 million were included within Accrued liabilities on the Consolidated Balance Sheet. The major classes of assets and liabilities primarily include net Inventory of $51 million and net Fixed assets of $37 million. In the first quarter of 2019, Rockwell Collins completed the sale of all businesses which were held for sale as of December 31, 2018.
On November 26, 2018, the Company announced its intention to separate into three independent companies. Following the separations, the Company will operate as an aerospace company comprised of Collins Aerospace Systems and the Pratt & Whitney businesses, and Otis and Carrier will become independent companies. The proposed separations are expected to be effected through spin-offs of Otis and Carrier that are intended to be tax-free for the Company’s shareowners for U.S. federal income tax purposes, and are expected to be completed in the first half of 2020. Separation of Otis and Carrier from UTC via spin-off transactions will be subject to the satisfaction of customary conditions, including, among others, final approval by the Company’s Board of Directors, receipt of tax rulings in certain jurisdictions and/or a tax opinion from external counsel (as applicable), the filing with the Securities and Exchange Commission (SEC) and effectiveness of Form 10 registration statements, and satisfactory completion of the merger.financing.

Customer
In addition to customer relationship intangible assets obtained through business combinations, 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 was $223$374 million and $205$223 million for the quarters ended March 31, 20182019 and 2017,2018, respectively.

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)ASC Topic 606: Revenue from Contracts with CustomersCustomers.
Performance Obligations. . Under Topic 606, aA 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.
Remaining Performance Obligations (RPO). RPO represents the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. As of March 31, 2019 our total RPO was approximately $117.5 billion. Of this total, we expect approximately 46% will be recognized as sales over the following 24 months. On December 31, 2018, we had approximately $115.5 billion of remaining performance obligations, are satisfiedat which time we expected to recognize approximately 46% of these remaining performance obligations as of a pointsales 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.next 24 months.
Over-time revenue recognition.Capitalized Contract Costs. 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)OEM products performance obligations are delivered to the customer.satisfied. 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 Standard changed 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 businesses, which previously accounted for revenue on a point in time basis are now required to use an over-time 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-completion for repair contracts within Otis and UTC Climate, Controls & Security; certain U.S. Government and commercial aerospace equipment contracts; and aerospace aftermarket service work. For these businesses, unrecognized salesperformance obligations related to the satisfied portion of the performance obligations of contracts in process as of the date of adoption of approximately $220 million were recorded through retained earnings. The ongoing effect of recording revenue on a percentage-of-completion 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; revenues and costs 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 benefit does not transfer to the customer and recognized as revenue when the OEM products are delivered. 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 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 2018satisfied. Capitalized 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; 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 quantifies the impact of adopting the New Revenue Standard on the statement of operations for the three months ended March 31, 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-completion 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 related to the timing of manufacturing cost recognition on early-contract OEM units sold during the quarter, with costs in excess of the contract average unit costs recorded through Cost of products sold.
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 following schedule reflects the effect of the New Revenue Standard on our balance sheetwere $1,072 million and $914 million as of March 31, 2018.

The decrease in Retained earnings of $472 million in the table above reflects $480 million of adjustments to the balance sheet as of January 1,2019 and December 31, 2018, resulting from the adoption of the New Revenue Standard, partially offset by higher reported net income under the new revenue standard. The declines in Accounts receivable, net, Inventories, Other assets, current,respectively 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 increaseare recognized 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.our Condensed Consolidated Balance Sheet.

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, 2019 and December 31, 2018 are as follows:

Under the New Revenue Standard,Contract assets increased $376 million during the quarter ended March 31, 2018, net2019 primarily due to revenue recognition in excess of customer billings, primarily on Pratt & Whitney commercial aftermarket and military engines contracts and various programs at Collins Aerospace Systems. Contract liabilities increased $484 million during the quarter ended March 31, 2019 primarily due to customer billings in excess of revenue on Otis maintenance contracts and on certain Pratt & Whitney commercial aftermarket contracts. We recognized revenue of $2.0 billion during the quarter ended March 31, 2019 related to contract liabilities increased to $6,531 million. This reflects the establishmentas of $6,365 million of net contract liabilities upon the adoption, and $7,031 million of advance payments from customers and reclassifications to receivables upon billing during the period. These increases were partially offset by the liquidation of beginning of period contract liabilities of $1,207 million as a result of revenue recognition. These increases were also offset by $5,676 million of revenue recognition within the period, and other less significant changes.
Remaining performance obligations ("RPO") are the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. As of MarchDecember 31, 2018, our total RPO are $99.8 billion. Of this total, we expect approximately 40% will be recognized as sales over the following 24 months.2018.

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 quarters ended March 31, 20182019 and 2017,2018, the number of stock awards excluded from the computation was approximately 4.312.2 million and 12.24.3 million, respectively.

Inventories also include capitalized contract development costs related to certain aerospace programs at UTC Aerospace Systems. As of December 31, 2017, these capitalized costs were $127 million, which will be liquidated as production units are delivered to customers. 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 are 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.

At March 31, 2018,2019, we had revolving credit agreements with various banks permitting aggregate borrowings of up to $4.35$10.35 billion,, pursuant to including: 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 2021.2021; and a $2.0 billion revolving credit agreement and a $4.0 billion term credit agreement, both of which we entered into on March 15, 2019 and which will expire on March 15, 2021 or, if earlier, the date that is 180 days after the date on which each of the separations of Otis and Carrier have been consummated. On March 15, 2019, we terminated the $1.5 billion revolving credit agreement that we entered into on November 26, 2018. As of March 31, 2018,2019, there were no borrowings under eitherany of these agreements. The
 As of March 31, 2019, the undrawn portions of thesethe $2.20 billion revolving credit agreements are alsoagreement and $2.15 billion multicurrency revolving credit agreement were available to serve as backup facilities for the issuance of commercial paper. As of March 31, 2018,2019, our maximum commercial paper borrowing limit was $4.35 billion. In April 2019, we increased our commercial paper borrowing limit to $6.35 billion with the undrawn portion of the $2.0 billion revolving credit agreement serving as additional backup for the issuance of commercial paper.
Commercial paper borrowings at March 31, 20182019 include approximately €750 million ($930849 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 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.
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 be funded only to the extent certain anticipated debt issuances are not completed prior to the completion of the merger. See Note 1 for additional discussion.

Note 6: Income Taxes
On December 22, 2017 Public Law 115-97 “An Act to ProvideThe decrease in the effective tax rate for Reconciliation Pursuant to Titles II and Vthe quarter ended March 31, 2019 is primarily the result 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 interpretive guidance and the absence of a TCJA tax consequences relating to states with current conformity tocharge recorded in the Internal Revenue Code are provisional amounts. Due tofirst quarter of 2018. In addition, the enactment date andCompany recognized a non-cash gain of approximately $40 million, primarily tax, complexitiesas a result of the TCJA, the Company has not completed its accounting related to these items.
Prior to enactmentclosure of a 2014 IRS audit of a subsidiary acquired as part of the TCJA, with few exceptions, U.S. income taxes had not been provided on undistributed earnings of UTC's international subsidiaries asRockwell Collins acquisition. This gain was partially offset by 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 theunfavorable pre-tax impact of a reversal of a related indemnity asset during 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 allquarter 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.approximately $23 million.
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 2006.2008.
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$390 million to $500$750 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,UTC tax years 2014, 2015 and 2016 are currently under review by the 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 of tax years 2014, 2015 and 2016(IRS), which is expected to conclude its review before the end of 2019. During the quarter ended March 31, 2019, the Company recognized a non-cash gain of approximately $40 million, primarily tax, as a result of the closure of an IRS audit of the 2014 tax year of a subsidiary acquired as part of UTC’s acquisition of Rockwell Collins. This gain was partially offset by the unfavorable pre-tax impact of a reversal of a related indemnity asset during the quarter of approximately $23 million. Another subsidiary of the Company is engaged in litigation in Italy which is currently pending before the Italian Supreme Court following favorable lower court decisions. The Italian Tax Authority announced an amnesty program which the Company is currently evaluating. Participation in the amnesty program would be expected to result in the recognition of a non-cash gain, primarily tax, in the range of $90 million to $110 million as early as the second quarter of 2019.
The Company will continue beyondto review and incorporate, as necessary, Tax Cuts and Jobs Act of 2017 (TCJA) changes related to forthcoming U.S. Treasury Regulations, other updates, and the next 12 months.finalization of the deemed inclusions to be reported on the Company’s 2018 U.S. federal income tax return.

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):

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.

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$18.1 billion and $19.120.1 billion at March 31, 20182019 and December 31, 20172018, respectively.

The effect of cash flow hedging relationships on accumulated other comprehensive income for the quarters ended March 31, 20182019 and 20172018 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 quarters ended March 31, 20182019 and 2017.2018. 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, 2018,2019, the net investment hedge is deemed to be effective.
Assuming current market conditions continue, a $36$49 million pre-tax gainloss 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, 2018,2019, all derivative contracts accounted for as cash flow hedges will mature by April 2022.2023.

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, 2018, there were no significant transfers in or out of Level 1 and Level 2.
As of March 31, 2018,2019, 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, 20182019 and December 31, 2017:2018:

We had commercial aerospace financing and other contractual commitments totaling approximately $15.1$16.2 billion and $15.315.5 billion as of March 31, 20182019 and December 31, 20172018, 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 ourthe aerospace businesses such as long-term trade accounts receivable, notes receivable,leases, and leasesnotes receivable. We also have other long-term receivables related toin 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, 20182019 and December 31, 2017.2018.

Customer credit ratings range from customers with an extremely strong capacity to meet financial obligations to customers whose uncollateralized receivables arereceivable is in default. There can be no assurance that actual results will not differ from estimates or that consideration of these factors in the future will not result in an increase or decrease to the allowance for credit losses on long-term receivables. Based upon the customer credit ratings, approximately $140 million and $170$150 million of our total long-term receivables were considered to bear high credit risk as of March 31, 20182019 and December 31, 2017, respectively.2018.
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 $17 million and $16 million as of March 31, 20182019 and December 31, 2017,2018, respectively, are individually evaluated for impairment. At March 31, 20182019 and December 31, 2017,2018, 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.impaired.

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) from the TCJA. We elected to reclassify the income tax effects of TCJA from AOCI of $745 million to retained earnings, effective January 1, 2019.
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 quarter ended March 31, 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.
Note 13: Variable Interest Entities
Pratt & Whitney holds a 61% net 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 20172018 Annual Report, incorporated by reference in our 20172018 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 20172018 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 20172018 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 thatrecommending the reduction of certain contract prices should be reduced to comply with various government regulations, including because, for example, cost or pricing data we submitted in negotiation of the contract prices or cost accounting practices used to price and negotiate those contracts may not have conformed to government regulations, or that certain payments be delayed or withheld.regulations. Some of these audit reports involvedrecommend that certain payments be repaid, delayed, or withheld, and may involve substantial amounts. We have made voluntary refunds in those cases we believe appropriate, have settled some allegations and, in some cases, continue to litigate negotiate and/or challenge certain matters.litigate. 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 ClaimClaims
As previously disclosed, in December 2013,In April 2019, a Divisional Administrative Contracting Officer (DACO) of the United States Defense Contract Management Agency (DCMA) asserted a claim against Pratt & Whitney to recover overpayments of approximately $1.73 billion plus interest (approximately $473 million through March 31, 2019). The claim is based on Pratt & Whitney's alleged

noncompliance with cost accounting standards from January 1, 2007 to March 31, 2019, due to its method of allocating independent research and development costs to government contracts. Pratt & Whitney believes that the claim is without merit and will be filing an appeal to the Armed Services Board of Contract Appeals (ASBCA).  
As previously disclosed, in December 2013, a DCMA DACO asserted a claim against Pratt & Whitney to recover overpayments of approximately $177 million plus interest (approximately $74.9$87.5 million through March 31, 2018)2019). 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 weASBCA. We continue to believe that the government’s claim is without merit.merit and the matter is currently scheduled for trial later this year. On December 18, 2018, a DCMA DACO issued a second claim against Pratt & Whitney that similarly alleges that its method of determining the cost of collaborator parts does not comply with the cost accounting standards for calendar years 2013 through 2017.  This second claim demands payment of $269 million plus interest (approximately $43.4 million), which we also believe is without merit and which Pratt & Whitney appealed to the ASBCA on January 9, 2019.  
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$244 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 $134 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$333 million and is principally recorded in Other long-term liabilities on our Condensed Consolidated Balance Sheet as of March 31, 2018.2019. 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 million, which is included primarily in Other assets on our Condensed Consolidated Balance Sheet as of March 31, 2018.2019.
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, the 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 end of each year, the Company evaluateswill evaluate all of these factors and, with input from an outside actuarial expert, makesmake 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 20172018 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: Leases
ASU 2016-02, Leases (Topic 842) and its related amendments (collectively, the New Lease Accounting Standard) are effective for reporting periods beginning after December 15, 2018. We adopted the New Lease Accounting Standard effective January 1, 2019 and elected the modified retrospective approach in which results for periods before 2019 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.
The New Lease Accounting Standard establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the Condensed Consolidated Balance Sheet for all leases with terms longer than 12 months. Leases are 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.
We have elected certain of the practical expedients available under the New Lease Accounting Standard upon adoption. We have applied the practical expedient which allows prospective transition to the New Lease Accounting Standard on January 1, 2019. Under the transition practical expedient, we did not reassess lease classification, embedded leases or initial direct costs. We have applied the practical expedient for short-term leases. We have lease agreements with lease and non-lease components. We have elected the practical expedients to combine these components for certain equipment leases. Additionally, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities. The adoption of the New Lease Accounting Standard did not have a material effect on our Consolidated Statement of Operations or Consolidated Statement of Cash Flows. Upon adoption, we recorded a $2.6 billion right-of-use asset and a $2.7 billion lease liability. The adoption of the New Lease Accounting Standard had an immaterial impact on retained earnings.
We enter into lease agreements for the use of real estate space, vehicles, information technology equipment, and certain otherequipment under operating and finance leases. We determine if an arrangement contains a lease at inception. Operating leases are included in Operating lease right-of-use assets, Accrued liabilities, and Operating lease liabilities in our Condensed Consolidated Balance Sheet. Finance leases are not considered significant to our Condensed Consolidated Balance Sheet or Condensed Consolidated Statement of Operations. Finance lease right-of-use assets at March 31, 2019 of $81 million are included in Other assets in our Condensed Consolidated Balance Sheet. Finance lease liabilities at March 31, 2019 of $86 million are included in Long term debt currently due, and Long term debt in our Condensed Consolidated Balance Sheet.

Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments, and use the implicit rate when readily determinable. We determine our incremental borrowing rate through market sources including relevant industry rates. Our lease right-of-use assets also include any lease pre-payments and exclude lease incentives. Certain of our leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. We exclude variable payments from lease right-of-use assets and lease liabilities, to the extent not considered fixed, and instead, expense variable payments as incurred. Variable lease expense and lease expense for short duration contracts is not a material component of lease expense. Our leases generally have remaining lease terms of 1 to 20 years, some of which include options to extend leases. The majority of our leases with options to extend are up to 5 years with the ability to terminate the lease within 1 year. The exercise of lease renewal options is at our sole discretion and our lease right-of-use assets and liabilities reflect only the options we are reasonably certain that we will exercise. Lease expense is recognized on a straight-line basis over the lease term.
In limited instances we act as a lessor, primarily for commercial aerospace engines and certain heating, ventilation and air conditioning (HVAC) systems and commercial equipment, all of which are classified as operating leases. These leases are not significant to our Condensed Consolidated Balance Sheet or Condensed Consolidated Statement of Operations.
Operating lease expense for the quarter ended March 31, 2019 was $159 million.
Supplemental cash flow information related to operating leases was as follows:

Prior to the adoption of the New Lease Accounting Standard, rental commitments on an undiscounted basis were approximately $2.9 billion at December 31, 2018 under long-term non-cancelable operating leases and were payable as follows: $683 million in 2019, $544 million in 2020, $407 million in 2021, $301 million in 2022, $235 million in 2023 and $746 million thereafter.

Note 16:17: Segment Financial Data
Our operations are classified into four principal segments: Otis, UTC Climate, Controls & Security,Carrier, Pratt & Whitney, and UTCCollins 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 recasted based on the adoption of ASU 2017-07.

Note 17:18: Accounting Pronouncements
In February 2016,August 2018, the FASB issued ASU 2016-02,2018-13, LeasesFair Value Measurement (Topic 842)820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU assetremoves the disclosure requirements for the amount of and a lease liability on the balance sheetreasons 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 allbetween Level 1 and Level 2 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 capital and operating leases and lessors for sales-type, direct financing, and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We expect that upon adoption we will recognize ROU assets and lease liabilities and that the amounts could be material. We dofair value hierarchy. This standard did not expect the ASU to have a material impact on our cash flows or results of operations.financial statement disclosures. We early adopted this standard effective January 1, 2019.

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.
In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities. The amendments in this update for determining whether a decision-making fee is a variable interest require reporting entities to consider indirect interests held through related parties under common control on our consolidateda proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in generally accepted accounting principles (GAAP)). Therefore, these amendments likely will result in more decision makers not having a variable interest through their decision-making arrangements. These amendments also will create alignment between determining whether a decision making fee is a variable interest and determining whether a reporting entity within a related party group is the primary beneficiary of a VIE. If fewer decision-making fees are considered variable interests, the focus on determining which party within a related party group under common control may have a controlling financial statements. However,we expectinterest will be shifted to the variable interest holders in the group with more significant economic interests. This will significantly reduce the risk that upon adoption we will recognize a reclassification from AOCI to retained earnings thatdecision makers with insignificant direct and indirect interests could be material. We do not expectdeemed the primary beneficiary of a VIE.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. The amendments in this update make targeted improvements GAAP for collaborative arrangements as follows: clarify that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. In those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements; add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606; and require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer.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.

With respect to the unaudited condensed consolidated financial information of UTC for the quarters ended March 31, 20182019 and 2017,2018, 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, 2018,26, 2019, 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 Interim Financial Information

We have reviewed the accompanying condensed consolidated balance sheet of United Technologies Corporation and its subsidiaries (the “Company”) as of March 31, 20182019, and the related condensed consolidated statements of operations, of comprehensive income, of changes in equity and of cash flows for the three-month periods ended March 31, 20182019 and 2017,2018, 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 CorporationCompany as of December 31, 2017,2018, 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 8,7, 2019, which included a paragraph describing a change in the manner of accounting for revenue from contracts with customers and net periodic benefit cost in the 2018 financial statements, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet information as of December 31, 20172018 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’sCompany’s management. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the CorporationCompany in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

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,Carrier, Pratt & Whitney, and UTCCollins Aerospace Systems. Otis and UTC Climate, Controls & SecurityCarrier are referred to as the "commercial businesses," while Pratt & Whitney and UTCCollins Aerospace Systems are referred to as the "aerospace businesses."
The current status of significant factors affecting our business environment in 20182019 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 20172018 Annual Report, which is incorporated by reference in our 20172018 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 & SecurityCarrier 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 billion and $1.3 billion for the quarters ended March 31, 2018 and 2017, 10% and 9% of total UTC sales for those periods, respectively. The defense portion of our aerospace business is affected bylevels, changes in market demand and the global political environment. Total sales to the U.S. Government were $2.4 billion and $1.6 billion for the quarters ended March 31, 2019 and 2018, 13% and 10% of total UTC sales for those periods, respectively. 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 2018.2019.
As has been previously disclosed, on November 26, 2018, the Company announced its intention to separate into three independent companies. Following the separations, the Company will operate as an aerospace company comprised of Collins Aerospace Systems and the Pratt & Whitney businesses, and Otis and Carrier will become independent companies. The proposed separations are expected to be effected through spin-offs of Otis and Carrier that are intended to be tax-free for the Company’s shareowners for U.S. federal income tax purposes, and are expected to be completed in the first half of 2020. Separation of Otis and Carrier from UTC via spin-off transactions will be subject to the satisfaction of customary conditions, including, among others, final approval by the Company’s Board of Directors, receipt of tax rulings in certain jurisdictions and/or a tax opinion from external counsel (as applicable), the filing with the Securities and Exchange Commission (SEC) and effectiveness of Form 10 registration statements, and satisfactory completion of financing.
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 quarter ended March 31, 2018,2019, our investment in business acquisitions was $125$19 million, which primarily reflects an acquisitionincludes a number of small acquisitions 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. 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 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 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-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. To help manage the cash flow and liquidity resulting from the proposed acquisition, we have suspended share repurchases, excluding activity relating to our employee savings plans.Otis.
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 2018.2019. See Part I, Item 1A, "Risk Factors" in our 20172018 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 20172018 Annual Report, incorporated by reference in our 20172018 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 There have been no 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 contractschanges 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 overcritical accounting estimates during 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 three monthsquarter ended March 31, 2018 and the balance sheet as of March 31, 2018.2019.

Interest expense, net increased 8%88% for the quarter ended March 31, 2018 relative to the prior year.2019. The increase in interest expense reflects the impact of the May 4, 2017August 16, 2018 issuance of notes representing $4$11 billion in aggregate 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: the 6.8% notes in February 2018 representing $1.5$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 inof aggregate principal. The average maturity of our long-term debt at March 31, 20182019 is approximately 1211 years.
Income Taxes
 Quarter Ended March 31,
 2018 2017
Effective tax rate27.6% 28.5%
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.

 Quarter Ended March 31,
 2019 2018
Effective tax rate21.8% 27.6%
The decrease in the effective tax rate for the quarter ended March 31, 20182019 is primarily due tothe result of Tax Cuts and Jobs Act of 2017 (TCJA) interpretive guidance and the absence of a reductionTCJA tax charge recorded in the first quarter of 2018. In addition, the estimated full year forecasted effectiveCompany recognized a non-cash gain of approximately $40 million, primarily tax, rate as a result of the enactmentclosure of TCJA. In addition, the rate reflects a tax charge2014 IRS audit of $44 million primarily related to provisional adjustments associated with regulatory guidance issued during the first quarter regarding the deemed repatriation provisionsa subsidiary acquired as part of the TCJA.Rockwell Collins acquisition. This isgain was partially offset by the absenceunfavorable pre-tax impact of a reversal of a related indemnity asset during the quarter of approximately $23 million.
The Company will continue to review and incorporate as necessary TCJA changes related to forthcoming U.S. Treasury Regulations, other updates, and the finalization of the unfavorable tax impact in the March 31, 2017 period relateddeemed inclusions to the gainbe reported on the sale of UTC Climate Control & Security’s investment in Watsco, Inc.
Company’s 2018 U.S. federal income tax return.
As shown in the table above, the effective tax rate for the quarterthree months ended March 31, 20182019 is 27.6%21.8%; the effective income tax rate for the same period, excluding restructuring, non-operational nonrecurring items is 25.0%21.7%. We estimate our full year 2018 annual effective income taxThe rate is still subject to be approximately 25.5%, excluding restructuring, non-operational nonrecurring itemschange as guidance and adjustmentsinterpretations related to the TCJA.

TCJA continue to be finalized. We anticipate some variability in the tax rate quarter to quarter from potential discrete items. The Company expects to incur tax costs associated with the portfolio separation transactions beginning in the second quarter of 2019 through the final spin-off transactions in 2020.

 $69
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.
20182019 Actions. During the quarter ended March 31, 2018,2019, we recorded net pre-tax restructuring charges of $12$73 million relating to ongoing cost reduction actions initiated in 20182019. We expect to incur additional restructuring charges of $40$31 million to complete these actions. We are targeting to complete in 20182019 and 20192020 the majority of the remaining workforce and facility related cost reduction actions initiated in 2018.2019. 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%93% 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 quarter ended March 31, 2018,2019, we had cash outflows of approximately $4$15 million related to the 20182019 actions.
20172018 Actions. During the quarterquarters ended March 31, 20182019 and 2017,2018, we recorded net pre-tax restructuring charges of $51$23 million and $24$12 million, respectively, for actions initiated in 20172018. We expect to incur additional restructuring charges of $103$56 million to complete these actions. We are targeting to complete in 20182019 the majority of the remaining workforce and facility related cost reduction actions initiated in 2017.2018. We expect recurring pre-tax savings in continuing operations to increase over the two-year period subsequent to initiating the actions to approximately $207$260 million annually, of which, approximately $43$35 million was realized during the quarter ended March 31, 2018.2019. Approximately 81%94% of the total expected pre-tax chargecharges will require cash payments, which we have and expect to continue to fund with cash generated from operations. During the quarter ended March 31, 2018,2019, we had cash outflows of approximately $39$75 million related to the 20172018 actions.
In addition, during the quarter ended March 31, 2018,2019, we recorded net pre-tax restructuring costs totaling $6$16 million for restructuring actions initiated in 20162017 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 quarters ended March 31, 20182019 and 20172018 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 & SecurityCarrier 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'sCarrier'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 & SecurityCarrier customarily offers its customers incentives to purchase products. The principal incentive program provides reimbursements to distributors for offering promotional pricing on UTC Climate, Controls & SecurityCarrier 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 & SecurityCarrier equipment orders in the quarter ended March 31, 2018 increased 10%2019 decreased 2% in comparison to the same period of the prior year, drivenas decreases in transport refrigeration (26%) and commercial refrigeration (2%), were partially offset by increases in transport refrigeration (37%North America residential HVAC equipment (7%) and residentialfire and security products (5%).

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% in the first two months of 2018.2019.
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)long-term aftermarket service agreements at Pratt & Whitney and long-term aftermarket service agreements at UTCCollins Aerospace Systems. FMPsThese agreements 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 offeringsproducts enter our customers' fleets under long-term service agreements and legacy fleets
are retired. For the first three months of 2018,2019, as compared with 2017,2018, total commercial aerospace aftermarket sales increased 18%64% at Collins Aerospace Systems (up 8% excluding the impact of the Rockwell Collins acquisition). Pratt & Whitney commercial aerospace aftermarket sales for the first three months of 2019 were consistent with the prior year.
Operating profit in the quarter ended March 31, 2019 included net unfavorable changes in aerospace contract estimates totaling $12 million, primarily reflecting net unfavorable contract adjustments at Pratt & Whitney and 16% at UTC Aerospace Systems.
We record changes in contract estimates using the cumulative catch-up method.Whitney. Operating profit in the quarter ended March 31, 2018 included significant net unfavorable changes in aerospace contract estimates totaling $41 million, primarily reflecting net unfavorable net contract adjustments recorded at Pratt & Whitney and UTCCollins 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.

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.flows. For 2018,2019, we expect cash flows from continuing operations, net of capital expenditures, to approximate $4.5 billion to $5.0 billion.billion, including $1.5 billion of one-time cash payments related to the portfolio separation. 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, 2018,2019, we had cash and cash equivalents of $7,667$6,240 million, of which approximately 51%66% 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. PriorThe Company no longer intends to enactment of the TCJA, with few exceptions, U.S. income taxes had not been provided onreinvest certain undistributed earnings of UTC'sits international subsidiaries as the Company had intended to reinvest such earnings permanently outsidethat have been previously taxed in the U.S. or to repatriateAs such, in the fourth quarter of 2018, it has recorded the taxes therewith. For the remainder of the Company’s undistributed international earnings, only when it wasunless tax effective to do so. The Company continuesrepatriate, UTC will continue to evaluatepermanently reinvest these earnings. We have repatriated $812 million of cash for 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 with 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.quarter ended March 31, 2019.
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, 20182019 and December 31, 2017,2018, the amount of such restricted cash was approximately $37$42 million and $33$60 million, respectively.

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%52% at March 31, 2018, remained2019 is consistent with December 31, 2018 and increased 600 basis points from March 31, 2018, primarily reflecting additional borrowings used to finance the prior year.acquisition of Rockwell Collins as well as the acquisition of Rockwell Collins' outstanding debt.

At March 31, 2019, we had credit agreements with various banks permitting aggregate borrowings of up to $10.35 billion, including: a $2.20 billion revolving credit agreement and a $2.15 billion multicurrency revolving credit agreement, both of which expire in August 2021, a $2.0 billion revolving credit agreement and a $4.0 billion term credit agreement, both of which we entered into on March 15, 2019 and which will expire on March 15, 2021 or, if earlier, the date that is 180 days after the date on which each of the separations of Otis and Carrier have been consummated. On March 15, 2019, we terminated the $1.5 billion revolving credit agreement that we entered into on November 26, 2018. As of March 31, 2019, there were no borrowings under any of these agreements. As of March 31, 2019, the undrawn portions of the $2.20 billion revolving credit facility and $2.15 billion multicurrency revolving credit agreement were available to serve as backup facilities for the issuance of commercial paper. 
As of March 31, 2019, our maximum commercial paper borrowing limit was $4.35 billion with borrowing of €750 million ($849 million). In April 2019, we increased our commercial paper borrowing limit to $6.35 billion with the undrawn portion of the March 15, 2019 $2.0 billion revolving credit agreement serving as additional backup for the issuance of 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.
At March 31, 2018, weWe 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, 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, 2018, our maximum commercial paper borrowing limit was $4.35 billion.
Commercial paper borrowings at March 31, 2018 include approximately €750 million ($930 million) of euro-denominated commercial paper.
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.
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 and 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 proposed acquisition, we have suspended share repurchases, excluding activity relating to our 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 $3.8 billion of overseas cash forduring the quarter ended March 31, 2018.

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 quarter ended March 31, 20182019 was $540$1,047 million lowerhigher than the same period in 2017. This decrease in cash flows provided by operations is2018 driven by an increaseimprovement in working capital of $497and lower payments related to the Canadian government settlement. Cash outflows for working capital decreased $527 million in the quarter ended March 31, 2019 over the prior period, primarily due to an increase inresulting from improved collections of 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 factoringat Pratt & Whitney. Factoring activity resulted in a decrease of approximately $560$380 million in cash generated from operating activities induring the quarter ended March 31, 2018,2019, as compared to the prior year. This decrease was primarily driven by Pratt & Whitney partially offset by increased factoring at Collins Aerospace Systems. Factoring activity does not reflect the factoring of certain aerospace receivables performed at customer request for which we are compensated by the customer for the extended paymentcollection cycle.
In the quarter ended March 31, 2019, cash outflows from working capital were $445 million. Contract assets, current increased $215 million due to work performed in excess of billings at Collins Aerospace Systems, Pratt & Whitney, and Carrier. Inventory increased $697 million primarily driven by an increase in production work in process for the Geared Turbo Fan at Pratt & Whitney, seasonal build in the HVAC businesses at Carrier, and increases at Collins Aerospace Systems. Other assets increased $165 million due to an increase in prepaid expense. Accounts payable and accrued liabilities decreased $588 million primarily due to higher collaborator share payments at Pratt & Whitney. These outflows were partially offset by decreases in Accounts receivable of $849 million primarily due to improved collections at Pratt & Whitney and increases in Contract liabilities, current of $371 million driven by seasonality of billings at Otis.
In the quarter ended March 31, 2018, cash outflows from working capital were $972 million. Accounts receivablesreceivable increased due to an increase in sales volume driven by UTC Climate, Controls & SecurityCarrier's North American HVAC Residential business and UTCCollins 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 maintenancelong-term aftermarket service contracts and government contracts at Pratt & Whitney. Inventory increased in the quarter primarily driven by UTC Climate, Controls & SecurityCarrier's seasonal build and an increase in production work in process for the A320 NEOA320neo in the aerospace businesses. These increases were partially offset by increases in accounts payable and accrued liabilities, driven by the higher inventory purchasing activity and customer advances at Pratt & Whitney as well as an increase in current contract liabilities driven by seasonal advanced billings and progress payments on major contracts at Otis and the timing of billings on aftermarket contracts at Pratt & Whitney.
In the quarter ended March 31, 2017, inventories increased $654 million, primarily in our aerospace businesses supporting an increase in forecasted OEM deliveries and related aftermarket demand, and at UTC Climate, Controls & Security primarily driven by seasonal demand in our North American HVAC and refrigeration businesses. 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 million in cash generated from operating activities of continuing operations in the quarter ended March 31, 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 quarter ended March 31, 20182019 and 20172018 were approximately $37$32 million and $46$37 million, respectively. Although our domestic pension plans are approximately 102%99% funded on a projected benefit obligation basis as of March 31, 2018,2019, and we are not required to make additional contributions through the end of 2028,2024, we may elect to make discretionary contributions in 2018.2019. We expect to make total contributions of approximately $100 million to our global defined benefit pension plans in 2018.2019. Contributions to our global defined benefit pension plans in 20182019 are expected to meet or exceed the current funding requirements.

The increase$582 million decrease in cash flows used in investing activities in the quarter ended March 31, 20182019 compared to March 31, 2017 of $837 million2018 primarily relates to receipts on derivatives contracts, the absence of net proceeds received of $596 million from UTC Climate, Controls & Security's sale of investmentsreduction in Watsco, Inc. in the quarter ended March 31, 2017 as well as an increase in customer financing asset of $94 million,acquisition activity, and an increase in payment from settlements of derivatives contracts of $108 million.disposition activity.
Capital expenditures for the quarter ended March 31, 2018 ($337 million)2019 of $363 million primarily relate to investments in production capacity at Pratt & Whitney new facilities at UTC Climate, Controls & Security, as well asand several small projects at UTCCollins Aerospace Systems.

Cash investments in businesses in the quarter ended March 31, 2018 ($125 million)2019 of $19 million consisted of small acquisitions at Otis. Dispositions of businesses in the quarter ended March 31, 2019 of $133 million primarily consisted of an acquisition at Pratt & Whitney. We do not expect to have additional significant acquisition spend, other than the expected acquisition ofbusinesses held for sale associated with the Rockwell Collins. However, actual acquisition spending may vary depending upon the timing, availability and appropriate value of acquisition opportunities.

Customer financing activities in the quarter ended March 31, 2019 were a net use of cash of $241$173 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. 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.fleets. 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$16.2 billion at March 31, 20182019 related to commercial aircraft and certain contractual rights to provide product on new aircraft platforms, of which up to $0.8$1.5 billion may be required to be disbursed during the remainder of 2018.2019. We had commercial aerospace financing and other contractual commitments of approximately $15.3$15.5 billion at December 31, 2017.2018.
During the quarter ended March 31, 2018,2019, our collaboration intangible assets increased by approximately $78$87 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 inflow of approximately $92 million during the quarter end March 31, 2019 compared to a net cash outflow of approximately $221 million and $113 million during the quarter ended March 31, 2018 and 2017, respectively.

At March 31, 2018,2019, management had remaining authority to repurchase approximately $2.3$1.9 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$29 million to repurchase approximately 188256 thousand shares of our common stock during the quarter ended March 31, 2018.

PART II – OTHER INFORMATION

Item 1.    Legal Proceedings

Telephone Consumer Protection Act
As previously disclosed, UTC Fire & Security Americas Corporation, Inc. (UTCFS) was named as a defendant in numerous putative class actions that were filed on behalf of purported classes 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 contravention of the Telephone Consumer Protection Act (TCPA).  In each putative class action suit, plaintiffs sought injunctive relief and monetary damages.  Each violation under the TCPA provides for $500 in statutory damages or up 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.
DOJ/SEC Investigations
As previously disclosed, in December 2013 and January 2014, UTC made voluntary disclosures to the United States Department of Justice (DOJ), the Securities and Exchange Commission (SEC) Division of Enforcement and the United Kingdom’s Serious Fraud Office to report the status of its internal investigation regarding a non-employee sales representative retained by United Technologies International Operations, Inc. (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 discussions with the SEC staff to resolve this matter. Because these discussions are ongoing, we cannot predict the outcome or the consequences thereof at this time.
See Note 15: Contingent Liabilities, for discussion regarding othermaterial legal proceedings.
Except as otherwise noted above, there have been no material developments in legal proceedings. For previously reported information about legal proceedings refer to Part I, Item 3, "Legal Proceedings," of our 20172018 Form 10-K.

On October 14, 2015, our Board of Directors authorized a share repurchase program for up to $12 billion of our common stock, replacing the program announced on July 19, 2015. At March 31, 2018,2019, the maximum dollar value of shares that may yet be purchased under this current program was approximately $2,269$1,932 million. Under this program, shares may be purchased on the open market, in privately negotiated transactions, under accelerated share repurchase (ASR) 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. No shares were reacquired in transactions outside the program during the quarter ended March 31, 2018.
On September 4, 2017, we announced that we had entered into a merger agreement with Rockwell Collins, under which we will acquire Rockwell Collins. To manage the cash flow and liquidity impacts of these actions, we have suspended share repurchases, excluding activity required under our equity award programs and employee savings plans.2019.
