NOTE 2. BASIS OF PRESENTATION
Interim Condensed Financial Statements
The unaudited Condensed Consolidated Financial Statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of operations, financial position and cash flows. All such adjustments are of a normal recurring nature. The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles in the United States of America (GAAP) pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted as permitted by such rules and regulations.
These interim condensed financial statements should be read in conjunction with the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.2017. Our interim period financial results for the three month periods presented are not necessarily indicative of results to be expected for any other interim period or for the entire year. The year-end Condensed Consolidated Balance Sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP.
Reclassifications
Certain amounts for prior year periods have been reclassified to conform to the presentation of the current year.
Use of Estimates in Preparation of Financial Statements
Preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts presented and disclosed in our Condensed Consolidated Financial Statements. Significant estimates and assumptions in these Condensed Consolidated Financial Statements require the exercise of judgment and are used for, but not limited to, allowance for doubtful accounts, estimates of future cash flows and other assumptions associated with goodwill and long-lived asset impairment tests, useful lives for depreciation and amortization, warranty programs, determination of discount rate and other assumptions for pension and other postretirement benefit costs, income taxes and deferred tax valuation allowances, lease classification and contingencies. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be different from these estimates.
Reporting Period
Our reporting period usually ends on the Sunday closest to the last day of the quarterly calendar period. The first quarters of 20172018 and 20162017 ended on April 21 and April 3,2, respectively. Our fiscal year ends on December 31, regardless of the day of the week on which December 31 falls.

Accelerated Share RepurchaseNOTE 3. REVENUE RECOGNITION
On February 9, 2016,
Revenue Recognition Accounting Pronouncement Adoption
In May 2014, the Financial Accounting Standards Board (FASB) amended its standards related to revenue recognition to replace all existing revenue recognition guidance and provide a single, comprehensive model for all contracts with customers. The revised standard contains principles to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that we entered intowill recognize revenue to depict the transfer of goods or services to customers at an accelerated share repurchase (ASR) agreement withamount that we expect to be entitled to in exchange for those goods or services. The guidance provides a third party financial institutionfive-step analysis of transactions to repurchase $500 milliondetermine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of the time value of money in the transaction price and allowing estimation of variable consideration to be recognized before contingencies are resolved in certain circumstances. The amendment also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in those judgments as well as assets recognized from costs incurred to fulfill these contracts.
The standard allows either full or modified retrospective adoption effective for annual and interim periods beginning January 1, 2018. We adopted the standard using the modified retrospective approach. We elected to apply this guidance retrospectively only to contracts that were not completed at January 1, 2018.
We identified a change in the manner in which we account for certain license income. We license certain technology to our common stockunconsolidated joint ventures that meet the definition of functional under the standard, which requires that revenue be recognized at a point in time rather than the previous requirement of recognizing it over the license term. Using the modified retrospective adoption method, we recorded an adjustment to our previously announced share repurchase plans. Pursuantopening equity balance at January 1, 2018, to account for the differences between existing license income recorded and what would have been recorded under the new standard for contracts for which we started recognizing revenue prior to the adoption date. There was not a material impact on any individual year from this change.
We also identified transactions where revenue recognition was historically limited to the amount of billings not contingent on our future performance. With the allocation provisions of the new model, we accelerated the timing of revenue recognition for amounts related to satisfied performance obligations that would be delayed under the historical guidance. The impact of this change was not material.
On an ongoing basis, this amendment is not expected to have a material impact on our Condensed Consolidated Financial Statements, including our internal controls over financial reporting, but will result in expanded disclosures in the Notes to our Condensed Consolidated Financial Statements.

We recorded a net increase to opening retained earnings of $28 million, net of tax, as of January 1, 2018, due to the cumulative impact of adopting the new revenue standard, with the impact primarily related to our technology licenses that now qualify for point in time recognition rather than over time. The impact to any individual financial statement line item as a result of applying the new standard, as compared to the old standard, was not material for the quarter ended April 1, 2018.


Revenue Recognition Policies

Revenue Recognition Sales of Products

We sell to customers either through long-term arrangements or standalone purchase orders. Our long-term arrangements generally do not include committed volumes until underlying purchase orders are issued. Our performance obligations vary by contract, but may include diesel and natural gas engines and engine-related component products, including filtration, aftertreatment, turbochargers, fuel systems, transmissions, controls systems, air handling systems, and electric power generation systems, batteries, parts, maintenance services, and extended coverage.

Typically, we recognize revenue on the products we sell at a point in time, generally in accordance with shipping terms, which reflects the transfer of control to the customer. Since control of construction projects transfer to the customer as the work is performed, revenue on these projects is recognized based on the percentage of inputs incurred to date compared to the total expected cost of inputs, which is reflective of the value transferred to the customer. Revenue is recognized under long-term

maintenance and other service agreements over the term of the agreement we paidas underlying services are performed based on the full $500 million purchase price and received approximately 4.1 million shares at a price of $98.43 per share, representing approximately 80 percentpercentage of the sharescost of services provided to date compared to the total expected cost of services to be provided under the contract. Sales of extended coverage are recognized based on the pattern of expected costs over the extended coverage period or, if such a pattern is unknown, on a straight-line basis over the coverage period as the customer is considered to benefit from our stand ready obligation over the coverage period. In all cases, we believe cost incurred is the most representative depiction of the extent of service performed to date on a particular contract.

Our arrangements may include the act of shipping products to our customers after the performance obligation related to that product has been satisfied. We have elected to account for shipping and handling as activities to fulfill the promise to transfer goods and have not allocated revenue to the shipping activity. All related shipping and handling costs are accrued at the time of shipment.

Our sales arrangements may include the collection of sales and other similar taxes that are then remitted to the related taxing authority. We have elected to present the amounts collected for these taxes net of the related tax expense rather than presenting them as additional revenue.

We grant credit limits and terms to customers based upon traditional practices and competitive conditions. Typical terms vary by market, but payments are generally due in 90 days or less from invoicing for most of our product and service sales, while payments on construction and other similar arrangements may be due on an installment basis.

For contracts where the time between cash collection and performance is less than one year, we have elected to use the practical expedient that allows us to ignore the possible existence of a significant financing component within the contract. For contracts where this time period exceeds one year, generally the timing difference is the result of business concerns other than financing. We do have a limited amount of customer financing for which we charge or impute interest, but such amounts are immaterial to our Condensed Consolidated Statements of Income.

Sales Incentives

We provide various sales incentives to both our distribution network and OEM customers. These programs are designed to promote the sale of our products in the channel or encourage the usage of our products by OEM customers. When there is uncertainty surrounding these sales incentives, we may limit the amount of revenue we recognize under a contract until the uncertainty has been resolved. Sales incentives primarily fall into three categories:

Volume rebates;
Market share rebates; and
Aftermarket rebates.

For volume rebates, we provide certain customers with rebate opportunities for attaining specified volumes during a particular quarter or year. We consider the expected amount of these rebates at the time of the original sale as we determine the overall transaction price. We update our assessment of the amount of rebates that will be earned quarterly based on our best estimate of the volume levels the customer will reach during the measurement period. For market share rebates, we provide certain customers with rebate opportunities based on the percentage of their production that utilizes our product. These rebates are typically measured either quarterly or annually and we assess them at least quarterly to determine our current estimates of amounts expected to be repurchased. earned. These estimates are considered in the determination of transaction price at the time of the original sale based on the current market shares, with adjustments made as the level changes. For aftermarket rebates, we provide incentives to promote sales to certain dealers and end-markets. These rebates are typically paid on a quarterly, or more frequent, basis and estimates are made at the end of each quarter as to the amount yet to be paid. These estimates are based on historical experience with the particular program.

Sales Returns

The unsettledinitial determination of the transaction price may also be impacted by expected product returns. Rights of return do not exist for the majority of our sales, other than for quality issues. We do offer certain return rights in our aftermarket business, where some aftermarket customers are permitted to return small amounts of parts and filters each year, and in our power generation business, which sells portable generators to retail customers. An estimate of future returns is accounted for at the time of sale as a reduction in the overall contract transaction price based on historical return rates.


Multiple Performance Obligations

Our sales arrangements may include multiple performance obligations. We identify each of the material performance obligations in these arrangements and allocate the total transaction price to each performance obligation based on its relative selling price. In most cases, the individual performance obligations are also sold separately and we use that price as the basis for allocating revenue to the included performance obligations. When an arrangement includes multiple performance obligations and invoicing to the customer does not match the allocated portion of the ASR mettransaction price, unbilled revenue or deferred revenue is recorded reflecting that difference. Unbilled and deferred revenue are discussed in more detail below.

Long-term Contracts

Our long-term maintenance agreements often include a variable amount of transaction price. We are generally compensated under such arrangements on a cost per hour of usage basis. We typically can estimate the criteriaexpected usage over the life of the contract, but reassess the transaction price each quarter and adjust our recognized revenue accordingly. Certain maintenance agreements apply to generators used to provide standby power, which have limited expectations of usage. These agreements may include monthly minimum payments, providing some certainty to the total transaction price. For these particular contracts that relate to standby power, we limit revenue recognized to date to an amount representing the total minimums earned to date under the contract plus any cumulative billings earned in excess of the minimums. We reassess the estimates of progress and transaction price on a quarterly basis. For prime power arrangements, revenue is not subject to such a constraint and is generally equal to the current estimate on a percentage of completion basis times the total expected revenue under the contract.

Most of our contracts are for a period of less than one year. We have certain long-term maintenance agreements, construction contracts and extended warranty coverage arrangements that span a period in excess of one year. The aggregate amount of the transaction price for long-term maintenance agreements and construction contracts allocated to performance obligations that have not been satisfied as of April 1, 2018, was $643 million. We expect to recognize the related revenue of $239 million over the next 12 months and $404 million over periods up to 10 years. See NOTE 10 ,"PRODUCT WARRANTY LIABILITY," for additional disclosures on extended warranty coverage arrangements. Our other contracts generally are for a duration of less than one year or include payment terms that correspond to the value we are providing our customers.

Deferred and Unbilled Revenue

The timing of our billing does not always match the timing of our revenue recognition. When we are entitled to bill a customer in advance of when we are permitted to recognize revenue, we record deferred revenue. Deferred revenue may arise in construction contracts, where billings may occur in advance of performance or in accordance with specific milestones. Deferred revenue may also occur in long-term maintenance contracts, where billings are often based on usage of the underlying equipment, which generally follows a predictable pattern that often will result in the accumulation of collections in advance of our performance of the related maintenance services. Finally, deferred revenue exists in our extended coverage contracts, where the cash is collected prior to the commencement of the coverage period. Deferred revenue is included in our Condensed Consolidated Balance Sheets as a component of current liabilities for those expected to be accountedrecognized in revenue in a period of less than one year and long-term liabilities for those expected to be recognized as revenue in a period beyond one year. Deferred revenue is recognized as revenue as (or when) control of the underlying product, project or service passes to the customer under the related contract.
When we are not entitled to bill a customer until a period after we have recognized the related revenue, we recognize unbilled revenue. Unbilled revenue is included in our Condensed Consolidated Balance Sheets as a forward contract indexedcomponent of current assets for those expected to be collected in a period of less than one year and long-term assets for those expected to be collected in a period beyond one year. Unbilled revenue relates to our stockright to consideration for our completed performance under a contract. Unbilled revenue generally arises from contractual provisions that delay a portion of the billings on genset deliveries until commissioning occurs. Unbilled revenue may also occur when billings trail the provision of service in construction and qualifiedlong-term maintenance contracts. We periodically assess our unbilled revenue for impairment.

The following is a summary of our unbilled and deferred revenue and related activity:
In millions April 1,

 (128) 

(1) Relates to revenue recognized in the period from amounts included in contract liabilities at the beginning of the period. Revenue recognized
in the period from performance obligations satisfied in previous periods was immaterial.
We did not record any impairment losses on our unbilled revenues during the three months ended April 1, 2018.
Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable represent amounts billed to customers and not yet collected or amounts that have been earned, but may not be billed until the passage of time, and are recorded when the right to consideration becomes unconditional. Trade accounts receivable are recorded at the invoiced amount, which approximates net realizable value, and generally do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on our historical collection experience and by performing an analysis of our accounts receivable in light of the current economic environment. We review our allowance for doubtful accounts on a regular basis. In addition, when necessary, we provide an allowance for the full amount of specific accounts deemed to be uncollectible. Account balances are charged off against the allowance in the period in which we determine that it is probable the receivable will not be recovered. The allowance for doubtful accounts balances for the periods ended April 1, 2018 and December 31, 2017, were $17 million and $16 million, respectively, and bad debt write-offs were not material.

Contract Costs

We are required to record an asset for the incremental costs of obtaining a contract with a customer and other costs to fulfill a contract not otherwise required to be immediately expensed when we expect to recover those costs. The only material incremental cost we incur is commission expense, which is generally incurred in the same period as the underlying revenue. Costs to fulfill a contract are generally limited to customer-specific engineering expenses that do not meet the definition of research and development expenses. As a practical expedient, we have elected to recognize these costs of obtaining a contract as an equity transaction. This resultedexpense when the related contract period is less than one year. When the period exceeds one year, this asset is amortized over the life of the contract. We did not have any material capitalized balances at April 1, 2018.

Extended Warranty

In addition, we sell extended warranty coverage on most of our engines and on certain components. We consider a warranty to be extended coverage in any of the following situations:

When a $100 million reductionwarranty is sold separately or is optional (extended coverage contracts, for example) or
When a warranty provides additional services.

The consideration collected is initially deferred and is recognized as revenue in proportion to the costs expected to be incurred in performing services over the contract period. We compare the remaining deferred revenue balance quarterly to the estimated amount of future claims under extended warranty programs and provide an additional paid-in capital duringaccrual when the first quarter of 2016. The initial delivery of shares resulted in a reduction to our common stock outstanding used to calculate earnings per share in the first quarter of 2016.deferred revenue balance is less than expected future costs. See NOTE 10, "PRODUCT WARRANTY LIABILITY," for additional information.

NOTE 6. INCOME TAXES
Our effective tax rate for the year is expected to approximate 23.0 percent, excluding any discrete tax items that may arise.
Our effective tax rate for the three months ended April 1, 2018, was 37.9 percent and contained $78 million, or $0.47 per share, of unfavorable discrete tax items, primarily related to a 2017 Tax Cuts and Jobs Act (Tax Legislation) adjustment of $74 million. This includes $39 million associated with changes related to the Tax Legislation measurement period adjustment, detailed below, and $35 million associated with the one-time recognition of deferred tax charges at historical tax rates on intercompany profit in inventory.
Our effective tax rate for the three months ended April 2, 2017, was 26.1 percent and contained only immaterial discrete tax items.

The SEC issued guidance which addressed the uncertainty in the application of GAAP to the Tax Legislation where certain income tax effects could not be finalized at December 31, 2017. This guidance allows entities to record provisional amounts based on current estimates that are updated on a quarterly basis. As a result, our accounting for the effects of the Tax Legislation are not considered complete at this time. The final transition impacts of the Tax Legislation may differ from our estimates, possibly materially, due to, among other things, changes in interpretations of the Tax Legislation, any legislative action to address questions that arise because of the Tax Legislation, any changes in accounting standards for income taxes or related interpretations in response to the Tax Legislation, or any updates or changes to estimates we have utilized to calculate the transition impacts. The SEC requires final calculations to be completed within the one-year measurement period ending December 22, 2018, and reflect any additional guidance issued throughout the year. Any adjustments of provisional amounts will be reported in continuing operations in the period in which the estimates change. We have made provisional estimates of the effects of the Tax Legislation in three primary areas: (1) the one-time transition tax; (2) the withholding tax accrued on those earnings no longer considered permanently reinvested at December 31, 2017 and (3) our existing deferred tax balances. In January 2018, the Internal Revenue Service (IRS) issued guidance, adopted in the first quarter of 2018, which required adjustment of the one-time transition tax as shown in the table below.

(1)Unrealized gains and losses for available-for-sale debt securities are recorded in other comprehensive income (See NOTE 12, "ACCUMULATED OTHER COMPREHENSIVE LOSS," to our Condensed Consolidated Financial Statements for more information). Effective January 1, 2018, with the adoption of the FASB standard, all unrealized gains and losses for equity securities are recorded in other income, net in the Condensed Consolidated Statements of Income. See NOTE 14, "RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS," for detailed information about the adoption of this standard.

All marketable securities are classified as Level 2 securities. The fair value of Level 2 securities is estimated using actively quoted prices for similar instruments from brokers and observable inputs where available, including market transactions and third-party pricing services, or net asset values provided to investors. We do not currently have any Level 3 securities and there were no transfers between Level 2 or 3 during the first three months of 20172018 and for the year ended 2016.2017.

A description of the valuation techniques and inputs used for our Level 2 fair value measures wasis as follows:
Debt mutual funds— The fair value measure for the vast majority of these investments is the daily net asset value published on a regulated governmental website. Daily quoted prices are available from the issuing brokerage and are used on a test basis to corroborate this Level 2 input.
Bank debentures— These investments provide us with a contractual rate of return and generally range in maturity from three months to five years. The counterparties to these investments are reputable financial institutions with investment grade credit ratings. Since these instruments are not tradable and must be settled directly by us with the respective financial institution, our fair value measure is the financial institutions’ month-end statement.
Equity mutual funds— The fair value measure for these investments is the net asset value published by the issuing brokerage. Daily quoted prices are available from reputable third party pricing services and are used on a test basis to corroborate this Level 2 input measure.
Government debt securities— The fair value measure for these securities is broker quotes received from reputable firms. These securities are infrequently traded on a national stock exchange and these values are used on a test basis to corroborate our Level 2 input measure.
Debt mutual funds— The fair value measure for the vast majority of these investments is the daily net asset value published on a regulated governmental website. Daily quoted prices are available from the issuing brokerage and are used on a test basis to corroborate this Level 2 input.

Certificates of deposit— These investments provide us with a contractual rate of return and generally range in maturity from three months to five years. The counterparties to these investments are reputable financial institutions with investment grade credit ratings. Since these instruments are not tradable and must be settled directly by us with the respective financial institution, our fair value measure is the financial institution's month-end statement.
Equity mutual funds— The fair value measure for these investments is the net asset value published by the issuing brokerage. Daily quoted prices are available from reputable third party pricing services and are used on a test basis to corroborate this Level 2 input measure.
Available-for-sale debt securities— The fair value measure for these securities is broker quotes received from reputable firms. These securities are infrequently traded on a national stock exchange and these values are used on a test basis to corroborate our Level 2 input measure.

We can issue up to $2.75 billion of unsecured short-term promissory notes ("commercial paper") pursuant to our board authorized commercial paper programs. The programs facilitate the private placement of unsecured short-term debt through third party brokers. We intend to use the net proceeds from the commercial paper borrowings for general corporate purposes.
Revolving Credit Facilities
We have access to committed credit facilities that total $2.75 billion, including a $1.0 billion, 364-day facility that expires September 14, 2018 and a $1.75 billion, 5-year facility that expires on November 13, 2020. We intend to maintain credit facilities of a similar aggregate amount by renewing or replacing these facilities before expiration. Revolving credit facilities are maintained primarily to provide backup liquidity for our commercial paper borrowings, letters of credit and general corporate purposes.

NOTE 9.11. COMMITMENTS AND CONTINGENCIES
We are subject to numerous lawsuits and claims arising out of the ordinary course of our business, including actions related to product liability; personal injury; the use and performance of our products; warranty matters; product recalls; patent, trademark or other intellectual property infringement; contractual liability; the conduct of our business; tax reporting in foreign jurisdictions; distributor termination; workplace safety; and environmental matters. We also have been identified as a potentially responsible party at multiple waste disposal sites under U.S. federal and related state environmental statutes and regulations and may have joint and several liability for any investigation and remediation costs incurred with respect to such sites. We have denied liability with respect to many of these lawsuits, claims and proceedings and are vigorously defending such lawsuits, claims and proceedings. We carry various forms of commercial, property and casualty, product liability and other forms of insurance; however, such insurance may not be applicable or adequate to cover the costs associated with a judgment against us with respect to these lawsuits, claims and proceedings. We do not believe that these lawsuits are material individually or in the aggregate. While we believe we have also established adequate accruals pursuant to GAAP for our expected future liability with respect to pending lawsuits, claims and proceedings, where the nature and extent of any such liability can be reasonably estimated based upon then presently available information, there can be no assurance that the final resolution of any existing or future lawsuits, claims or proceedings will not have a material adverse effect on our business, results of operations, financial condition or cash flows.
We conduct significant business operations in Brazil that are subject to the Brazilian federal, state and local labor, social security, tax and customs laws. While we believe we comply with such laws, they are complex, subject to varying interpretations and we are often engaged in litigation regarding the application of these laws to particular circumstances.
Loss Contingency ChargesEngine System Campaign Accrual
Engine systems sold inDuring 2017, the U.S. must be certified to comply with the Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emission standards.and U.S. Environmental Protection Agency (EPA) selected certain of our pre-2013 model year engine systems for additional emissions testing. Some of these engine systems failed CARB and EPA andtests as a result of degradation of an aftertreatment component. We have not been issued an official notice from the CARB regulations require that in-use testing be performed on vehicles byor EPA regarding these particular engine systems. We continue to work with the emission certificate holder and reportedagencies to the EPA and CARB in order to ensure ongoing compliance withdevelop a resolution of these emission standards.matters. We are the holderdeveloping and testing a variety of this emission certificate for our engines, including engines installed in certain vehicles with one customer on which we did not also manufacture or sell the emission aftertreatment system. During 2015, a quality issue in certain of these third party aftertreatment systems caused some of our inter-related engines to fail in-use emission testing. In the fourth quarter of 2015, the vehicle manufacturer made a request that we assist in the design and bear the financial cost of a field campaign (Campaign)solutions to address the technical issue purportedly causing some vehicles to fail the in-use testing.
While we are not responsible for the warranty issues, related towhich could include a component that we did not manufacture or sell, as the emission compliance certificate holder, we are responsible for proposing a remedy to the EPAcombination of calibration changes, additional service practices and CARB. As a result, we have proposed actions to the agencies that we believe will address the emission failures. As the certificate holder, we expect to participate in the cost of the proposed voluntary Campaign andhardware changes.We recorded a charge of$60 $29 millionto cost of sales in 2015. The Campaign design was finalized with our OEM customer, reviewed withCondensed Consolidated Statements of Income in the EPA and submittedthird quarter of 2017 for final approval in 2016.the then expected cost of field campaigns to repair some of these engine systems. We have concluded based upon additional in-use emission testing performed, and further discussions with the agencies in 2016,the first quarter of 2018, that the Campaignfield campaigns should be expanded to include a larger population of vehicles manufactured by this one OEM. Weour engine systems that are subject to the aftertreatment component degradation, including our model years 2010 through 2015. As a result, we recorded an additional chargescharge of $138$187 million, or $0.87 per share, to cost of sales in our Condensed Consolidated Statements of Income ($94 million recorded in the Components segment and $93 million in 2016the Engine segment) in the first quarter of 2018, to reflect theour current estimated cost of our participationthese expanded campaigns. See NOTE 10, "PRODUCT WARRANTY LIABILITY," for additional information.
For the engine populations under evaluation, we are in the Campaign. We continueprocess of finalizing the form and extent of solutions to workaddress the technical matters. The accrual recorded in the first quarter of 2018 represents our current best estimate of the expected cost of our recommended courses of action to address these matters and is based upon certain assumptions about the effectiveness of our proposed solutions and the agencies' acceptance of those solutions. Since there are many variables with respect to these degradation issues, it is difficult to assess whether our future costs will be consistent with our OEM customercurrent accrual for this matter. If, through the course of our ongoing internal work to resolvedevelop and test our proposed solutions, it becomes apparent that more extensive repairs are required for certain populations of engine systems, or if the allocationagencies do not accept our proposed solutions, then further charges may be recorded in the period in which our current assumptions change. It is reasonably possible that such

changes in assumption could occur, with a range of costs forzero, if our current proposed solutions are effective and approved, up to an incremental exposure of approximately $400 million above our recorded accrual at the Campaign, including pending litigation betweenend of the parties. The Campaign is not expected to be completed for some time and our final cost could differ from the amount we have recorded.first quarter.
We do not currently expect any fines or penalties from the EPA or CARB related to this matter.

The Campaign began in the fourth quarter of 2016. The remaining accrual of $181 million is included in ''Other accrued expenses'' in our Condensed Consolidated Balance Sheets.
Guarantees and Commitments
Periodically, we enter into guarantee arrangements, including guarantees of non-U.S. distributor financings, residual value guarantees on equipment under operating leases and other miscellaneous guarantees of joint ventures or third-party obligations. At April 2, 2017,1, 2018, the maximum potential loss related to these guarantees was $43$55 million.
We have arrangements with certain suppliers that require us to purchase minimum volumes or be subject to monetary penalties. At April 2, 2017,1, 2018, if we were to stop purchasing from each of these suppliers, the aggregate amount of the penalty would be approximately $119$73 million, of which $41$18 million relates to a contract with a components supplier that extends tothrough 2018 and $35$15 million relates to a contract with a power systems supplier that extends to 2019. Most of these arrangements enable us to secure critical components. We do not currently anticipate paying any penalties under these contracts.
We enter into physical forward contracts with suppliers of platinum, palladium and copper to purchase minimum volumes of the commodities at contractually stated prices for various periods, not to exceed two years. At April 2, 2017,1, 2018, the total commitments under these contracts were $24$31 million. These arrangements enable us to fix the prices of these commodities, which otherwise are subject to market volatility.
We have guarantees with certain customers that require us to satisfactorily honor contractual or regulatory obligations, or compensate for monetary losses related to nonperformance. These performance bonds and other performance-related guarantees were $83$107 million at April 2, 2017.1, 2018.
Indemnifications
Periodically, we enter into various contractual arrangements where we agree to indemnify a third-party against certain types of losses. Common types of indemnities include:
product liability and license, patent or trademark indemnifications;
asset sale agreements where we agree to indemnify the purchaser against future environmental exposures related to the asset sold; and
product liability and license, patent or trademark indemnifications;
asset sale agreements where we agree to indemnify the purchaser against future environmental exposures related to the asset sold; and
any contractual agreement where we agree to indemnify the counterparty for losses suffered as a result of a misrepresentation in the contract.
We regularly evaluate the probability of having to incur costs associated with these indemnities and accrue for expected losses that are probable. Because the indemnifications are not related to specified known liabilities and due to their uncertain nature, we are unable to estimate the maximum amount of the potential loss associated with these indemnifications.

NOTE 11.13. OPERATING SEGMENTS
Operating segments under GAAP are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (CODM), or decision-making group, in deciding how to allocate resources and in assessing performance. Our CODM is the President and Chief Operating Officer.
Our reportable operating segments consist of Engine, Distribution, Components, Power Systems and Power Systems.Electrified Power. This reporting structure is organized according to the products and markets each segment serves. The Engine segment produces engines (15 liters and less in size) and associated parts for sale to customers in on-highway and various off-highway markets. Our engines are used in trucks of all sizes, buses and recreational vehicles, as well as in various industrial applications, including construction, agriculture, power generation systems and other off-highway applications. The Distribution segment includes wholly-owned and partially-owned distributorships engaged in wholesaling engines, generator sets and service parts, as well as performing service and repair activities on our products and maintaining relationships with various OEMs throughout the world. The Components segment sells filtration products, aftertreatment systems, turbochargers, fuel systems and fuel systems.transmissions. The Power Systems segment is an integrated power provider, which designs, manufactures and sells engines (16 liters and larger) for industrial applications (including mining, oil and gas, marine and rail), standby and prime power generator sets, alternators and other power components. We formed the Electrified Power segment, effective January 1, 2018, which will provide fully electric and hybrid powertrain solutions along with innovative components and subsystems to serve all our markets as they adopt electrification, meeting the needs of our OEM partners and end customers.
Our Electrified Power segment will design, manufacture, sell and support electrified power systems ranging from fully electric to hybrid. We are currently developing the Cummins Electric Power Battery and the Cummins Hybrid Plug-In systems for urban bus, which are expected to launch in 2019 and 2020, respectively. We also design and manufacture battery modules, packs and systems for commercial, industrial and material handling applications. We use segment EBITa range of cell chemistries which are suitable for pure electric, hybrid and plug-in hybrid applications. In addition to electrified powertrains for urban bus, we intend to deliver product offerings to future markets, including pick-up and delivery applications and other markets as they adopt electric solutions. We invest in and utilize our internal research and development capabilities, along with strategic acquisitions and partnerships to meet our objectives.
Effective January 1, 2018, we changed our measure to EBITDA (defined as earnings before interest expense, income taxes, noncontrolling interests, depreciation and noncontrolling interests)amortization) as athe primary basis for the CODM to evaluate the performance of each of our reportable operating segments. EBITDA assists investors and debt holders in comparing our performance on a consistent basis without regard for depreciation and amortization, which can vary significantly depending upon many factors. Prior periods have been revised to reflect the current presentation. Segment amounts exclude certain expenses not specifically identifiable to segments.
The accounting policies of our operating segments are the same as those applied in our Condensed Consolidated Financial Statements. We prepared the financial results of our operating segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions. We allocate certain common costs and expenses, primarily corporate functions, among segments differently than we would for stand-alone financial information prepared in accordance with GAAP. These include certain costs and expenses of shared services, such as information technology, human resources, legal, finance and supply chain management. We do not allocate debt-related items, actuarial gains or losses, prior service costs or credits, changes in cash surrender value of corporate owned life insurance or income taxes to individual segments. Segment EBITEBITDA may not be consistent with measures used by other companies.

NOTE 12.14. RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
Accounting Pronouncements Recently Adopted
In March 2016, the Financial Accounting Standards Board (FASB) amended its standards related to the accounting for stock compensation which became effective for us beginningOn January 1, 2017. We2018, we adopted certain provisions prospectivelythe new revenue recognition standard in accordance with the standard, while others were required to be adopted retrospectively. The amendment replaced the requirement to record excess tax benefits and certain tax deficiencies in additional paid-in capital (APIC) with prospectively recording all excess tax benefits and tax deficiencies as income tax expense / benefit in the income statement. Excess tax benefits and deficiencies are required to be recorded as discrete items in the period in which they occur and were not materialGAAP.See NOTE 3, "REVENUE RECOGNITION," for three months ended April 2, 2017. In addition,detailed information about the standard impacted our Condensed Consolidated Statements of Cash Flows, as excess tax benefits are now required to be presented as an operating activity (we elected a retrospective presentation) and the cash paid to tax authorities when shares are withheld to satisfy the employer's statutory income tax withholding obligation are required to be presented as a financing activity (requiring retrospective presentation). This resulted in a net reclassification of $4 million from operating to financing activities for the three months ended April 3, 2016. Finally, in accordance with the standard, we elected to continue our historical approach of estimating forfeitures during the award's vesting period and adjusting our estimate when it is no longer probable that the employee will fulfill the service condition. The adoption of the standard was not material to our diluted earnings per common share.this standard.
Accounting Pronouncements Issued But Not Yet Effective
In March 2017, the FASB amended its standards related to the presentation of pension and other postretirement benefit costs in the financial statements.statements beginning January 1, 2018. Under the new standard, we will beare required to separate service costs from all other elements of pension costs and reflect the other elements of pension costs outside of operating income in ourCondensed Consolidated Statements of Income. In addition, the standard will limitlimits the amount eligible for capitalization (into inventory or self-constructed assets) to the amount of service cost. This portion of the standard will bewas applied on a prospective basis. The remainder of the new standard is effective for uswas applied on a retrospective basis beginning January 1, 2018. While we are still evaluatingusing a practical expedient as the impactestimation basis for the reclassification of this standard, the change in presentation will likely result in a decrease inprior period non-service cost components of net periodic benefit cost from operating income primarily due to non-operating income. As a result, we revised amounts from the requirement to present the effectsfirst quarter of expected return on plan assets outside2017 in our Condensed Consolidated Statements of operating income.Income by decreasing cost of sales by $4 million, increasing selling, general and administrative expense by $10 million and increasing non-operating other income, net by $6 million.
In August 2016, the FASB amended its standards related to the classification of certain cash receipts and cash payments.payments which became effective for us beginning January 1, 2018. The new standard will makemade eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. Adoption of this standard did not have a material impact on our financial statements.
In January 2016, the FASB amended its standards related to the accounting for certain financial instruments which became effective for us beginning January 1, 2018. This amendment addresses certain aspects of recognition, measurement, presentation and disclosure. The standard resulted in a cumulative effect increase to opening retained earnings of $2 million in our Condensed Consolidated Financial Statements.
Accounting Pronouncements Issued But Not Yet Effective
In August 2017, the FASB amended its standards related to accounting for derivatives and hedging. These amendments allow the initial hedge effectiveness assessment to be performed by the end of the first quarter in which the hedge is designated rather than concurrently with entering into the hedge transaction. The changes also expand the use of a periodic qualitative hedge effectiveness assessment in lieu of an ongoing quantitative assessment performed throughout the life of the hedge. The revision removes the requirement to record ineffectiveness on cash flow hedges through the income statement when a hedge is considered highly effective, for fiscal years beginning after December 15, 2017,instead deferring all related hedge gains and interim periods within those fiscal years. Earlylosses in other comprehensive income until the hedged item impacts earnings. The modifications permit hedging the contractually-specified price of a component of a commodity purchase and revises certain disclosure requirements. The amendments are effective January 1, 2019 and early adoption is permitted includingin any interim period or fiscal year prior to the effective date. The revised standard is required to be adopted on a modified retrospective basis for any cash flow or net investment hedge relationships that exist on the date of adoption in an interim period. If an entity early adoptsand prospectively for disclosures. We do not expect the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that electsto have a material effect on our Consolidated Financial Statements and are still evaluating early adoption must adopt all of the amendments in the same period. The new standard will require adoption on a retrospective basis unless it is impracticable to apply, in which case it would be required to apply the amendments prospectively as of the earliest date practicable. We are in the process of evaluating the impact this standard will have on our Consolidated Statements of Cash Flows.adoption.
In June 2016, the FASB amended its standards related to the accounting for credit losses on financial instruments. This amendment introduces new guidance for accounting for credit losses on instruments including trade receivables and held-to-maturity debt securities. The new rules are effective for annual and interim periods beginning after December 15, 2019. Early adoption is

adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are in the processdo not expect adoption of evaluating thethis standard to have a material impact the amendment will have on our Consolidated Financial Statements.
In February 2016, the FASB amended its standards related to the accounting for leases. Under the new standard, lessees will now be required to recognize substantially all leases on the balance sheet as both a right-of-use-assetright-of-use asset and a liability. The standard will continue to have two types of leases for income statement recognition purposes: operating leases and finance leases. Operating leases will result in the recognition of a single lease expense on a straight-line basis over the lease term similar to the treatment for operating leases under today's standards. Finance leases will result in an accelerated expense similar to the accounting for capital leases under today's standards. The determination of a lease classification as operating or finance will occur in a manner similar to today's standard. The new standard also contains amended guidance regarding the identification of embedded leases in service contracts and the identification of lease and non-lease components of an arrangement. The new standard is effective on January 1, 2019, with early adoption permitted. The standard currently requires adoption on a full retrospective basis; however, the FASB has recently approved an amendment to allow adoption on a modified retrospective basis.  While the amendment is not yet published, we would expect to adopt on a modified retrospective basis assuming the amendment is published as approved. We are still evaluating the impact the standard could have on our Consolidated Financial Statements; however, while, including our internal controls over financial reporting. While we have not yet quantified the amount, we do expect the standard will have a material impact on our Consolidated Balance Sheets due to the recognition of additional assets and liabilities for operating leases.
In January 2016, the FASB amended its standards related to the accounting for certain financial instruments. This amendment addresses certain aspects of recognition, measurement, presentation and disclosure. The new rules will become effective for annual and interim periods beginning after December 15, 2017. Early adoption is not permitted. We are in the process of evaluating the impact the amendment will have on our Consolidated Financial Statements.
In May 2014, the FASB amended its standards related to revenue recognition. This amendment replaces all existing revenue recognition guidance and provides a single, comprehensive revenue recognition model for all contracts with customers. The standard contains principles that we will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that we will recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that we expect to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of the time value of money in the transaction price and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The amendment also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in those judgments and assets recognized from costs incurred to fulfill a contract. The standard allows either full or modified retrospective adoption effective for annual and interim periods beginning January 1, 2018. We are in the process of evaluating the impact the amendment will have on our Consolidated Financial Statements. We expect to adopt the standard using the modified retrospective approach. While we have not yet completed our evaluation process, we have identified that a change will be required related to our accounting for remanufactured product sales that include an exchange of the used product, referred to as core. Revenue is not currently recognized related to the core component unless the used product is not returned. Under the new standard, the transaction will be accounted for as a gross sale and a purchase of inventory. As a result the exchange will increase both sales and cost of sales, in equal amounts, related to core. This will not impact gross margin dollars, but will impact the gross margin percentage. We are still quantifying the amount of this change. We have also identified transactions where revenue recognition is currently limited to the amount of billings not contingent on our future performance. With the allocation provisions of the new model, we expect to accelerate the timing of revenue recognition for amounts related to satisfied performance obligations that would have been delayed under the current guidance. We do not expect the impact of this change to be material, but we are still quantifying the impact.
NOTE 13. SUBSEQUENT EVENT
On April 10, 2017, we entered into an agreement to form a joint venture with Eaton Corporation PLC, subject to regulatory approvals. We will purchase a 50 percent interest in the new venture named Eaton Cummins Automated Transmission Technologies, for approximately $600 million in cash. The joint venture will design, assemble, sell and support medium-duty and heavy-duty automated transmissions for the commercial vehicle market, including new product launches. We expect the transaction to close in the third quarter of 2017, at which time we will consolidate the results of the joint venture in our Components segment as we have a majority voting interest in the venture by virtue of a tie-breaking vote on the board of directors.

EXECUTIVE SUMMARY AND FINANCIAL HIGHLIGHTS
We are a global power leader that designs, manufactures, distributes and services diesel and natural gas engines and engine-related component products, including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, andtransmissions, electric power generation systems, batteries and electrified power systems. We sell our products to original equipment manufacturers (OEMs), distributors and other customers worldwide. We have long-standing relationships with many of the leading manufacturers in the markets we serve, including PACCAR Inc, Daimler Trucks North America, Navistar International Corporation and Fiat Chrysler Automobiles.Automobiles (Chrysler). We serve our customers through a network of approximately 600500 wholly-owned and independent distributor locations and over 7,4007,500 dealer locations in more than 190 countries and territories.
Our reportable operating segments consist of Engine, Distribution, Components, Power Systems and Power Systems.Electrified Power. This reporting structure is organized according to the products and markets each segment serves. The Engine segment produces engines (15 liters and less in size) and associated parts for sale to customers in on-highway and various off-highway markets. Our engines are used in trucks of all sizes, buses and recreational vehicles, as well as in various industrial applications, including construction, agriculture, power generation systems and other off-highway applications. The Distribution segment includes wholly-owned and partially-owned distributorships engaged in wholesaling engines, generator sets and service parts, as well as performing service and repair activities on our products and maintaining relationships with various OEMs throughout the world. The Components segment sells filtration products, aftertreatment systems, turbochargers, fuel systems and fuel systems.transmissions. The Power Systems segment is an integrated power provider, which designs, manufactures and sells engines (16 liters and larger) for industrial applications (including mining, oil and gas, marine and rail), standby and prime power generator sets, alternators and other power components. We formed the Electrified Power segment, effective January 1, 2018, which will provide fully electric and hybrid powertrain solutions along with innovative components and subsystems to serve all our markets as they adopt electrification, meeting the needs of our OEM partners and end customers.
Our Electrified Power segment will design, manufacture, sell and support electrified power systems ranging from fully electric to hybrid. We are currently developing the Cummins Electric Power Battery and the Cummins Hybrid Plug-In systems for urban bus, which are expected to launch in 2019 and 2020, respectively. We also design and manufacture battery modules, packs and systems for commercial, industrial and material handling applications. We use a range of cell chemistries which are suitable for pure electric, hybrid and plug-in hybrid applications. In addition to electrified powertrains for urban bus, we intend to deliver product offerings to future markets, including pick-up and delivery applications and other markets as they adopt electric solutions. We invest in and utilize our internal research and development capabilities, along with strategic acquisitions and partnerships to meet our objectives.
Our financial performance depends, in large part, on varying conditions in the markets we serve, particularly the on-highway, construction and general industrial markets. Demand in these markets tends to fluctuate in response to overall economic conditions. Our sales may also be impacted by OEM inventory levels, production schedules and stoppages. Economic downturns in markets we serve generally result in reduced sales of our products and can result in price reductions in certain products and/or markets. As a worldwide business, our operations are also affected by currency, political, economic and regulatory matters, including adoption and enforcement of environmental and emission standards, in the countries we serve. As part of our growth strategy, we invest in businesses in certain countries that carry high levels of these risks such as China, Brazil, India, Mexico, Russia and countries in the Middle East and Africa. At the same time, our geographic diversity and broad product and service offerings have helped limit the impact from a drop in demand in any one industry or customer or the economy of any single country on our consolidated results.
Worldwide revenues increased 721 percent in the three months ended April 2, 2017,1, 2018, as compared to the same period in 2016,2017, with all operating segments reporting higher revenue. Revenue in the U.S. and Canada improved by 22 percent primarily due to higher demand in most global industrial markets, increased demand in all Components businesses, organic sales growththe North American on-highway markets, increased industrial demand (especially in the oil and gas and construction markets), increased demand in our Distribution segmentdistribution business (primarily in the engines, parts and service product lines) and sales related to the consolidationacquisition of North American distributors since December 31, 2015, partially offset by unfavorable foreign currency fluctuations and decreased demand in most on-highway markets.the automated transmission business during 2017. International demand growth (excludes the U.S. and Canada) in the first quarter of 2017 improved revenues by 1720 percent, with sales up in most of our markets, especially in Europe, Latin America, China, India, RussiaAsia Pacific and the U.K.India. The increase in international sales was primarily due to increased on-highway truck demand (especially in Latin America), favorable foreign currency impacts of 5 percent of international sales (primarily the Euro, Chinese renminbi and British pound), product sales to meet new emission requirements for trucks in India and increased demand in industrial markets (especially construction markets in China and mining markets in EasternChina and Europe).

Effective January 1, 2018, we changed our measure to EBITDA (defined as earnings before interest expense, income taxes, noncontrolling interests, depreciation and increased demandamortization) as a primary basis for the Chief Operating Decision Maker to evaluate the performance of each of our operating segments. EBITDA assists investors and debt holders in all Components businesses (especially in China), partially offset by unfavorable foreign currency impacts of 3 percent (primarily incomparing our performance on a consistent basis without regard for depreciation and amortization, which can vary significantly depending upon many factors. Prior periods have been revised to reflect the British pound and Chinese renminbi). Revenue in the U.S. and Canada improved by 1 percent primarily due to increased Distribution segment sales related to organic growth and the consolidation of North American distributors, partially offset by decreased demand in the North American on-highway markets.

The increase in gross margin dollars for the three months ended April 1, 2018, versus the comparable period in 2017, was
primarily due to higher volumes and improved pricing, partially offset by increased campaign costs of $93 million related to a campaign for engine systems from model years 2010 to 2015 that are subject to aftertreatment
component degradation. See Note 11, "COMMITMENTS AND CONTINGENCIES," to the Condensed Consolidated
Financial Statements for additional information. The increase in research, development and engineering expenses was
primarily due to lower expense recovery and higher compensation expense driven by headcount growth. The decrease in equity, royalty and interest income from investees was primarily due to lower earnings at Beijing Foton Cummins Engine Co., Ltd. and Dongfeng Cummins Engine Company, Ltd., partially offset by higher earnings at Tata Cummins Ltd. and Cummins Westport, Inc.

Electrified Power Segment Results
We formed the Electrified Power segment during the first quarter of 2018. The primary focus of the segment is on research and development activities around fully electric and hybrid powertrain solutions. Our intellectual property is developed both in house as well as through acquisitions. As of April 1, 2018, we completed two acquisitions, which provided us with battery systems intellectual property as well as start-up sales of $2 million. We invested $7 million in research and development activities, which along with the gross margins generated by our acquisitions and selling and administrative expenses resulted in a segment EBITDA loss of $10 million for three months ended April 1, 2018. See NOTE 13, "OPERATING SEGMENTS," to our Condensed Consolidated Financial Statements for additional information.

LIQUIDITY AND CAPITAL RESOURCES
Key Working Capital and Balance Sheet Data
We fund our working capital with cash from operations and short-term borrowings, including commercial paper, when necessary. Various assets and liabilities, including short-term debt, can fluctuate significantly from month to month depending on short-term liquidity needs. As a result, working capital is a prime focus of management attention. Working capital and balance sheet measures are provided in the following table:

During the first three months of 2017,2018, the lowerhigher working capital requirements resulted in a cash outflow of $128$446 million compared to a cash outflow of $140$128 million in the comparable period in 2016. 2017, primarily due to the payment of higher accrued variable compensation expense in the first quarter of 2018.
Net cash used in investing activities decreased $361increased $9 million for the three months ended April 2, 2017,1, 2018, versus the comparable period in 2016,2017, primarily due to lower net liquidations of investments in marketable securities of $377$106 million, partially offset by higher cash flows from derivatives not designated as hedges of $51 million and lower capital expenditures and investments in internal use software of $21 million.
Net cash used in financing activities decreased $472$112 million for the three months ended April 2, 2017,1, 2018, versus the comparable period in 2016,2017, primarily due to lower repurchases of common stock of $524 million and higher borrowings of commercial paper of $12$233 million, partially offset by lower proceeds from borrowingshigher repurchases of $105common stock of $112 million.
The effect of exchange rate changes on cash and cash equivalents for the three months ended April 2, 2017,1, 2018, versus the comparable period in 2016,2017, increased $53$29 million primarily due to the British pound, which increased cash and cash equivalents by $46$21 million.

Sources of Liquidity 
We generate significant ongoing cash flow. Cashflow and cash provided by operations is our principal source of liquidity with $379 million provided inliquidity. For the three months ended April 2, 2017.

1, 2018, we used $117 million of cash in our operations primarily due to higher working capital requirements and lower net income as discussed above.

At April 2, 2017,1, 2018, we had $274$593 million of commercial paper outstanding, which effectively reduced the available capacity under our revolving credit facilityfacilities to $1.48$2.16 billion.
(3) The available capacity is net of letters of credit.
Cash, Cash Equivalents and Marketable Securities
A significant portion of our cash flowsflow is generated outside the U.S. The geographic location of our cash and marketable securities aligns well with our ongoing investments. We manage our worldwide cash requirements considering available funds among the many subsidiaries through which we conduct our business and the cost effectiveness with which those funds can be accessed. As a result, we do not anticipate any local liquidity restrictions to preclude us from funding our operating needs with local resources.
Debt Facilities and Other Sources of Liquidity
We have access to committed credit facilities that total $2.75 billion, including a $1.0 billion, 364-day facility that expires September 14, 2018 and a $1.75 billion, 5-year facility that expires on November 13, 2020. We intend to maintain credit facilities of a similar aggregate amount by renewing or replacing these facilities before expiration. Revolving credit facilities are maintained primarily to provide backup liquidity for our commercial paper borrowings, letters of credit and general corporate purposes.
We can issue up to $1.75$2.75 billion of unsecured short-term promissory notes ("commercial paper") pursuant to aour board authorized commercial paper program.programs. The program facilitatesprograms facilitate the private placement of unsecured short-term debt through third party brokers. We intend to use the net proceeds from the commercial paper programborrowings for general corporate purposes.
We have a $1.75 billion revolving credit facility, the proceeds of which can be used for general corporate purposes. This facility expires on November 13, 2020. The revolving credit facility is maintained primarily to provide backup liquidity for our commercial paper borrowings, letters of credit and general corporate purposes. The total combined borrowing capacity under the revolving credit facility and commercial paper program should not exceed $1.75 billion.
As a well-known seasoned issuer, we filed an automatic shelf registration for an undetermined amount of debt and equity securities with the Securities and Exchange Commission on February 16, 2016. Under this shelf registration we may offer, from time to time, debt securities, common stock, preferred and preference stock, depositary shares, warrants, stock purchase contracts and stock purchase units.
Uses of Cash
ShareStock Repurchases
In December 2016, our Board of Directors authorized the acquisition of up to $1 billion of additional common stock upon completion of the 2015 repurchase plan. In the first three months of 2017,2018, we made the following purchases under the 2015 and 2016 stock repurchase program:programs:

plan.
We may continueintend to repurchase outstanding shares from time to time during 20172018 to enhance shareholder value and to offset the dilutive impact of employee stock based compensation plans.
Dividends
In July 2016,2017, our Board of Directors authorized an increase to our quarterly dividend of 5.15.4 percent from $0.975$1.025 per share to $1.025$1.08 per share. We paid dividends of $171$178 million during the three months ended April 2, 2017.
Agreement to Form a Joint Venture
On April 10, 2017, we entered into an agreement to form a joint venture with Eaton Corporation PLC, subject to regulatory approvals. We will purchase a 50 percent interest in the new venture named Eaton Cummins Automated Transmission Technologies, for approximately $600 million, which we will fund with a combination of cash and short-term debt. We expect the transaction to close in the third quarter of 2017.1, 2018.
Capital Expenditures
Capital expenditures, andincluding spending on internal use software, for the three months ended April 2, 2017,1, 2018, were $108$87 million compared to $84$108 million in the comparable period in 2016.2017. We continue to invest in new product lines and targeted capacity expansions. We plan to spend between $500$730 million and $530$760 million in 20172018 on capital expenditures as we continue with product launches and facility improvements. Approximately 50 percent of our capital expenditures are expected to be invested outside of the U.S. in 2017.2018.
Pensions
Our global pension plans, including our unfunded and non-qualified plans, were 110116 percent funded at December 31, 2016.2017. Our U.S. qualified plans, which represent approximately 5655 percent of the worldwide pension obligation, were 118131 percent funded and our U.K. plans were 121118 percent funded. The funded status of our pension plans is dependent upon a variety of variables and assumptions including return on invested assets, market interest rates and levels of voluntary contributions to the plans. In the first three months of 2017,2018, the investment returnloss on our U.S. pension trust was 3.11.5 percent while our U.K. pension trust returnloss was 2.70.5 percent. Approximately 7776 percent of our pension plan assets are held in highly liquid investments such as fixed income and equity securities. The remaining 2324 percent of our plan assets are held in less liquid, but market valued investments, including real estate, private equity, venture capital, opportunistic credit and insurance contracts. We anticipate making additional defined benefit pension contributions during the remainder of 20172018 of $91$29 million for our U.S. and U.KU.K. pension plans. Approximately $133$14 million of the estimated $134$38 million of U.S. and U.K. pension contributions for the full year are voluntary. These contributions may be made from trusts or company funds either to increase pension assets or to make direct benefit payments to plan participants. We expect our 20172018 net periodic pension cost to approximate $83$86 million.
Current Maturities of Short and Long-Term Debt
We had $274$593 million of commercial paper outstanding at April 2, 2017,1, 2018, that matures in less than one year. The maturity schedule of our existing long-term debt does not require significant cash outflows in the intermediate term. Required annual principal payments range from $4$8 million to $45$51 million over the next five years (including the remainder of 2017)2018). See Note 9, "DEBT," to the Condensed Consolidated Financial Statements for additional information.

Management's Assessment of Liquidity


Our financial condition and liquidity remain strong. Our solid balance sheet and credit ratings enable us to have ready access to credit and the capital markets. We assess our liquidity in terms of our ability to generate adequate cash to fund our operating, investing and financing activities. We believe our operating cash flow and liquidity provides us with the financial flexibility

needed to fund working capital, common stock repurchases, acquisitions, capital expenditures, dividend payments, projected pension obligations and debt service obligations. WeWhile we expect more efficient access to overseas earnings as a result of Tax Legislation, we will continue to generate cash from operations in the U.S. and maintain access to our revolving credit facility as noted above.



APPLICATION OF CRITICAL ACCOUNTING ESTIMATES
A summary of our significant accounting policies is included in Note 1, “SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES,” of the Notes to the Consolidated Financial Statements of our 20162017 Form 10-K, which discusses accounting policies that we have selected from acceptable alternatives.
Our Condensed Consolidated Financial Statements are prepared in accordance with generally accepted accounting principles that often require management to make judgments, estimates and assumptions regarding uncertainties that affect the reported amounts presented and disclosed in the financial statements. Management reviews these estimates and assumptions based on historical experience, changes in business conditions and other relevant factors they believe to be reasonable under the circumstances. In any given reporting period, our actual results may differ from the estimates and assumptions used in preparing our Condensed Consolidated Financial Statements.
Critical accounting estimates are defined as follows: the estimate requires management to make assumptions about matters that were highly uncertain at the time the estimate was made; different estimates reasonably could have been used; or if changes in the estimate are reasonably likely to occur from period to period and the change would have a material impact on our financial condition or results of operations. Our senior management has discussed the development and selection of our accounting policies, related accounting estimates and the disclosures set forth below with the Audit Committee of our Board of Directors. Our critical accounting estimates disclosed in the Form 10-K address the estimation of liabilities for warranty programs, accounting for income taxes and pension benefits.
A discussion of our critical accounting estimates may be found in the “Management’s Discussion and Analysis” section of our 20162017 Form 10-K under the caption “APPLICATION OF CRITICAL ACCOUNTING ESTIMATES.” Within the context of these critical accounting estimates, we are not currently aware of any reasonably likely events or circumstances that would result in different policies or estimates being reported in the first three months of 2017.2018.
RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
See Note 12,14, "RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS," in the Notes to Condensed Consolidated Financial Statements for additional information.
ITEM 3.  Quantitative and Qualitative Disclosures About Market Risk
A discussion of quantitative and qualitative disclosures about market risk may be found in Item 7A of our 20162017 Form 10-K. There have been no material changes in this information since the filing of our 20162017 Form 10-K. 
ITEM 4.  Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Exchange Act Rules 13a-15(e) and 15d-15(e). Based upon that evaluation, our Chief Executive OfficerCEO and our Chief Financial OfficerCFO concluded that our disclosure controls and procedures were effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is (1) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (2) accumulated and communicated to management, including our Chief Executive OfficerCEO and Chief Financial Officer,CFO, to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
There has been no change in our internal control over financial reporting during the quarter ended April 2, 2017,1, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 

PART II.  OTHER INFORMATION
ITEM 1.  Legal Proceedings
We are subject to numerous lawsuits and claims arising out of the ordinary course of our business, including actions related to product liability; personal injury; the use and performance of our products; warranty matters; product recalls; patent, trademark or other intellectual property infringement; contractual liability; the conduct of our business; tax reporting in foreign jurisdictions; distributor termination; workplace safety; and environmental matters. We also have been identified as a potentially responsible party at multiple waste disposal sites under U.S. federal and related state environmental statutes and regulations and may have joint and several liability for any investigation and remediation costs incurred with respect to such sites. We have denied liability with respect to many of these lawsuits, claims and proceedings and are vigorously defending such lawsuits, claims and proceedings. We carry various forms of commercial, property and casualty, product liability and other forms of insurance; however, such insurance may not be applicable or adequate to cover the costs associated with a judgment against us with respect to these lawsuits, claims and proceedings. We do not believe that these lawsuits are material individually or in the aggregate. While we believe we have also established adequate accruals pursuant to U.S. generally accepted accounting principles for our expected future liability with respect to pending lawsuits, claims and proceedings, where the nature and extent of any such liability can be reasonably estimated based upon then presently available information, there can be no assurance that the final resolution of any existing or future lawsuits, claims or proceedings will not have a material adverse effect on our business, results of operations, financial condition or cash flows.
The disclosure set forth under "Loss Contingency" in Note 9, "COMMITMENTS AND CONTINGENCIES," to the Condensed Consolidated Financial Statements is incorporated herein by reference.
We conduct significant business operations in Brazil that are subject to the Brazilian federal, state and local labor, social security, tax and customs laws. While we believe we comply with such laws, they are complex, subject to varying interpretations and we are often engaged in litigation regarding the application of these laws to particular circumstances.
ITEM 1A.  Risk Factors
In addition to other information set forth in this report, you should consider other risk factors discussed in Part I, "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2016,2017, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K or the "CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING INFORMATION" in this Quarterly report are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently judge to be immaterial also may materially adversely affect our business, financial condition or operating results.

Authorized Plan, completing this program, and repurchased $117 million shares of common stock under the 2016 authorization.
During the three months ended April 2, 2017,1, 2018, we repurchased 24,5073,621 shares from employees in connection with the Key Employee Stock Investment Plan which allows certain employees, other than officers, to purchase shares of common stock on

an installment basis up to an established credit limit. Loans are issued for five-year terms at a fixed interest rate established at the date of purchase and may be refinanced after their initial five-year period for an additional five-year period. Participants must hold shares for a minimum of six months from date of purchase. If the shares are sold before the loan is paid off, the employee must wait six months before another share purchase may be made. We hold participants’ shares as security for the loans and would, in effect repurchase shares if the participant defaulted in repayment of the loan. There is no maximum amount of shares that we may purchase under this plan.
