Forward-Looking and Cautionary Statements

This Quarterly Report on Form 10-Q contains certain statements that are, or may be deemed to be, "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act, as amended. The Private Securities Litigation Reform Act of 1995 provides safe harbor provisions for forward-looking information. Some of the statements contained in this Quarterly Report on Form 10-Q are forward-looking statements. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. The words "believe," "may," "estimate," "continue," "anticipate," "intend," "plan," "expect" and similar expressions are intended to identify forward-looking statements. Forward-looking statements include information concerning our possible or assumed future financial performance and results of operations.

We have based these statements on our assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe are appropriate in the circumstances. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly affect expected results, and actual future results could differ materially from those described in such statements. While it is not possible to identify all factors, factors that could cause actual future results to differ materially include the risks and uncertainties disclosed in our 2017 Annual Report on Form 10-K contained in Part I under "Risk Factors" and in this Quarterly Report on Form 10-Q in Part II under "Risk Factors."

Many of these factors are beyond our ability to control or predict. Any of these factors, or a combination of these factors, could materially and adversely affect our future financial condition or results of operations and the ultimate accuracy of the forward-looking statements. These forward-looking statements are not guarantees of our future performance, and our actual results and future developments may differ materially and adversely from those projected in the forward-looking statements. We caution against putting undue reliance on forward-looking statements or projecting any future results based on such statements or on present or prior earnings levels. In addition, each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise any forward-looking statement.

KBR, Inc.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Description of Company and Significant Accounting Policies

KBR, Inc., a Delaware corporation, was formed on March 21, 2006 and is headquartered in Houston, Texas. KBR, Inc. and its wholly owned and majority-owned subsidiaries (collectively referred to herein as "KBR", the "Company", "we", "us" or "our") is a global provider of differentiated, professional services and technologies across the asset and program life-cycle within the government services and hydrocarbons industries. Our capabilities include research and development, feasibility and solutions development, specialized technical consulting, systems integration, engineering and design service, process technologies, program management, construction services, commissioning and startup services, highly specialized mission and logistics support solutions, and asset operations and maintenance services and other support services to a diverse customer base, including government and military organizations of the U.S., U.K. and Australia and a wide range of customers across the hydrocarbons value chain.

Principles of Consolidation

Our condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR and our wholly owned and majority-owned subsidiaries and VIEs of which we are the primary beneficiary. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. See Note 11 to our condensed consolidated financial statements for further discussion on our equity investments and VIEs. The cost method is used when we do not have the ability to exert significant influence. All material intercompany balances and transactions are eliminated in consolidation.

Amounts classified as "Costs and estimated earnings in excess of billings on uncompleted contracts" and "Billings in excess of costs and estimated earnings on uncompleted contracts" on the consolidated balance sheets of our Annual Report on Form 10-K for the year ended December 31, 2017 have been reclassified as "Contract assets" and "Contract liabilities" on the condensed consolidated balance sheets.

We have evaluated all events and transactions occurring after the balance sheet date but before the financial statements were issued and have included the appropriate disclosures.

Segment Reorganization

Effective January 1, 2018, we changed the name of our Engineering & Construction segment to the "Hydrocarbons Services" segment. This change reflects strategic shifts we have made in this business over recent years to evolve to more recurring and reimbursable engineering, consulting and industrial maintenance services, coupled with our de-emphasis in engaging in fixed price EPC projects except for those that fit within our commercial discipline.

Also effective January 1, 2018, we changed the structure of our internal organization in a manner that caused our consulting business to be moved from the Technology & Consulting business segment to the Hydrocarbons Services (formerly E&C) business segment. As of January 1, 2018, our segments consist of the following five reportable segments:

• Government Services

• Technology

• Hydrocarbons Services

• Non-Strategic Business

• Other

See Note 3 to our condensed consolidated financial statements for further discussion on our segments. We have presented our segment results reflecting these changes for all periods presented. In conjunction with the change in segments, the Company evaluated its goodwill associated with the technology and consulting reporting units using Level 3 fair value inputs, and no impairment indicators were identified.

Use of Estimates

The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses

11

during the reporting period. Actual results could differ from those estimates. Areas requiring significant estimates and assumptions by our management include but are not limited to the following:

• project revenues, costs and profits on engineering and construction contracts, including recognition of estimated losses on uncompleted contracts

• project revenues, award fees, costs and profits on government services contracts

• provisions for uncollectible receivables

• provisions for client claims and recoveries of costs from subcontractors, vendors and others

• provisions for income taxes and related valuation allowances and tax uncertainties

• recoverability of goodwill

• recoverability of other intangibles and long-lived assets and related estimated lives

• recoverability of equity method and cost method investments

• valuation of pension obligations and pension assets

• accruals for estimated liabilities, including litigation accruals

• consolidation of VIEs

• valuation of share-based compensation

• valuation of assets and liabilities acquired in business combinations

We classify revenue contract liabilities as current or noncurrent based on the timing of when we expect to recognize revenue. The noncurrent portion of contract liabilities is included in "Other liabilities" in our condensed consolidated balance sheets. If the underlying estimates and assumptions upon which the financial statements are based change in the future, actual amounts may differ from those included in the accompanying condensed consolidated financial statements.

Adoption of New Accounting Standards

ASU 2014-09, Revenue from Contracts with Customers, codified as ASC Topic 606. On January 1, 2018, we adopted ASC Topic 606 and the related amendments ("ASC 606") using the modified retrospective method applied to those contracts that were not completed as of December 31, 2017. Results for operating periods beginning after January 1, 2018 are presented under ASC 606, while comparative information has not been restated and continues to be reported in accordance with the accounting standards in effect for those periods. See Note 2 for a description of our accounting policy resulting from adoption of ASC 606.

We recognized the cumulative effect of initially applying ASC 606 as an adjustment to retained earnings in the balance sheet as of January 1, 2018 as follows:

	Balance at		Adjustments Due to			Balance at
Dollars in millions	December 31, 2017		ASC 606			January 1, 2018

The impacts of adoption were primarily related to: (1) conforming our contracts recorded over time from previously acceptable methods to the cost-to-cost percentage of completion methodology, (2) combining certain deliverables that were previously considered separate deliverables into a single performance obligation, and (3) separating certain contracts that were previously considered one deliverable into multiple performance obligations.

The impacts of adoption on our opening balance sheet were primarily related to reclassification of amounts between "Accounts receivable, net of allowance for doubtful accounts" and "Contract assets" based on whether an unconditional ri

14

ght to consideration has been established or not, and the deferral of costs incurred and payments received to fulfill a contract, which were previously recorded in income in the period incurred or received but under the new standard will generally be capitalized and amortized over the period of contract performance.

In connection with the consolidation of certain previously unconsolidated VIEs associated with the Aspire Defence project in the first quarter of 2018, we elected to early adopt ASC 606 for each of the remaining unconsolidated Aspire Defence contracting entities effective January 1, 2018. As a result of the adoption by the Aspire Defence contracting entities, we identified multiple performance obligations associated with the project deliverables that were previously accounted for as a single deliverable under its contract with the MoD. In addition to the above impacts of adoption on revenue and gross margin, the cumulative effect of the adoption by Aspire Defence contracting entities resulted in sufficient additional income that had been previously recorded as "Deferred income from unconsolidated affiliates" on our condensed consolidated balance sheets in the amount of $101 million, which was reversed and included in the cumulative effect adjustment. Also, deferred construction income in the amount of $87 million previously recorded in "Equity in and advance to unconsolidated affiliates" was reversed and included in the cumulative effect adjustment as a result of the early adoption of ASC 606 by the Aspire Defence contracting entities. Except for the Aspire Defence contract entities, we have availed the SEC exemption under ASU 2017-13 to defer the application of ASC 606 to our remaining unconsolidated joint ventures until January 1, 2019.

Note 2. Significant Accounting Policies

Our significant accounting policies are detailed in "Note 1. Description of Company and Significant Accounting Policies" of our Annual Report on Form 10-K for the year ended December 31, 2017. The following section represents revisions to those accounting policies due to the adoption of ASC 606 and the separate presentation of acquisition and integration related costs.

Revenue Recognition

Revenue is measured based on the amount of consideration specified in a contract with a customer. Revenue is recognized when and as our performance obligations under the terms of the contract are satisfied, which generally occurs with the transfer of control of the goods or services to the customer.

To determine the proper revenue recognition method for contracts, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more

15

than one performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate a combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, which is mainly because we provide a significant service of integrating a complex set of tasks and components into a single project or capability. Contracts that cover multiple phases of the product lifecycle (development, construction and maintenance & support) are typically considered to have multiple performance obligations even when they are part of a single contract.

For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. In cases where we do not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We provide product warranties to customers that are included in the sale and are not priced or sold separately or do not provide customers with a service in addition to assurance of compliance with agreed-upon specifications. We do not consider these types of warranties to be separate performance obligations.

The following is a description of the principal activities from which we generate revenues by reportable segment:

Government Services

For most of government services, the customer contracts with us to provide support solutions to defense, space, aviation and other programs and missions through long-term service contracts. The performance obligations related to these long-term service contracts are primarily created through the issuance of task orders by the customer because a service contract generally does not meet the criteria to be considered a contract under ASC 606 since it does not obligate the customer to issue any task orders and could be canceled without substantive penalty under termination for convenience clauses. Accordingly, each task order releases us to perform specific portions of the overall scope in the service contract and is typically accounted for as a separate contract because the task order establishes the enforceable rights and obligations and payment terms. Task orders can include option periods that may be approved by the customer at a later date depending on the customer's future needs and budget availability.

Many of our government services contracts include variable consideration consisting of base fees (a profit percentage applied to our target cost) or award fees (additional consideration based on performance criteria, subject to final customer approval). Variable consideration can also arise from modifications to the scope of services resulting in unapproved change orders or customer claims. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted) that is reasonably available to us.

Many of our government services contracts are for labor at agreed hourly rates on a cost reimbursable basis to the customer. These contracts are accounted for as a series of distinct services because (a) the labor is provided as a continuous service, (b) each time increment of labor provided is distinct, (c) the nature of the services provided is substantially the same, and (d) the pattern of transfer is the same. In these types of contracts, the entire amount of consideration is recognized as labor is provided.

We also enter into base operations support contracts to provide the resources to operate bases, installations, camps, and stations of military departments. Our base operations support contracts are either fixed price contracts or cost reimbursable contracts. For fixed price contracts, we bill the customer a fixed monthly fee and recognize revenue over time on a straight-line basis where our level of effort remains substantially the same from month to month or where that is not the case, using a cost-to-cost input measure of progress as services are provided. For cost reimbursable contracts, we bill the customer all direct costs incurred each month plus an agreed provisional rate for overhead and fee, which are finalized at a later date. Revenue for cost reimbursable contracts is recognized as the direct costs are incurred and billed because the base operations represent a series of distinct services and the direct costs are consistent with our level of effort each month. For the purpose of revenue recognition of the variable elements of the contracts, we apply the variable consideration considerations described above.

Revenue on our other types of government services contracts is primarily recognized over time using the cost-to-cost input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress because it best depicts the transfer of assets to the customer, which occurs as we incur costs on the contracts. Contract costs include actual direct project costs incurred and an allocation of our indirect costs.

16

Under the typical payment terms of our government services contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones.

Hydrocarbons Services

For most of our hydrocarbons services projects, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability and are therefore accounted for as single performance obligations.

It is common for our hydrocarbons services contracts to contain incentive fees, performance bonuses, penalties (liquidated damages) or other provisions, including claims and change orders that may either increase or decrease the transaction price. Incentives and other performance bonuses generally are awarded upon achievement of certain performance metrics, program milestones or cost targets. Liquidated damage penalties in our contracts are generally capped at a percentage of the total contract value. Liquidated damages may be related to schedule delays, typically calculated based on a daily rate, or tied to performance guarantees.

Substantially all of our performance obligations related to hydrocarbons services contracts are satisfied over time as work progresses due to the continuous transfer of control to the customer. Typically, revenue is recognized over time using the cost-to-cost input measure to measure progress because it best depicts the transfer of goods and services to the customer, which occurs as we incur costs on our contracts. Contract costs include all direct material and labor costs and those indirect costs related to contract performance. Indirect costs, included in cost of revenues, include charges for such items as facilities, engineering, project management, quality control, bids and proposals and procurement.

Under the typical payment terms of our hydrocarbons services contracts, the customer makes advance payments as well as interim payments as work progresses. The advance payment generally is not considered a significant financing component as we normally expect to recognize the advance payments in revenue within a year of receipt as work progresses on the related performance obligation.

Technology

Our technology contracts consist primarily of licensing, basic engineering design (together, the "LBED"), proprietary equipment ("PEQ") or catalyst contracts. LBED contracts are combined into one performance obligation as they are entered into at the same time and the licensed technology requires engineering and design. We may further combine LBED and PEQ contracts into one performance obligation if the contracts were negotiated as a package with a single commercial objective, and the customer contracts with us to provide a significant service of integrating these distinct goods and services into a single project or capability.

It is common for our technology contracts to contain variable consideration including contingent milestone payments and penalties (liquidated damages) that may increase or decrease the transaction price. Contingent milestone payments are primarily related to decisions made by the customer after the LBED has been completed, such as a go or no-go decision on the project. Liquidated damage penalties in our technology contracts are typically triggered by late delivery and are calculated based on a weekly rate and are capped at a percentage of the total contract value.

Substantially all of our performance obligations related to technology contracts are satisfied over time as work progresses. Typically, revenue is recognized over time using the cost-to-cost input measure to measure progress because it best depicts the transfer of assets to the customer, which occurs as we incur costs on our contracts. Contract costs include all direct material and labor costs and those indirect costs related to contract performance and are recognized as the performance obligation is satisfied.

Under the typical payment terms of our technology contracts, the customer makes advance payments as well as interim payments as work progresses and certain progress milestones are met. The advance payment generally is not considered a significant financing component as we normally expect to recognize the advance payments in revenue within a year of receipt as work progresses on the related performance obligation.

Contract Estimates

Contract Modifications

17

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment.

As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly through a Company-wide disciplined project review process in which management reviews the progress and execution of our performance obligations and the estimate at completion (EAC). As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule and the related changes in estimates of revenues and costs. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer, among other variables.

We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the period it is identified.

Contracts are often modified to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

We account for contract modifications as a separate contract when the modification results in the promise to deliver additional goods or services that are distinct and the increase in price of the contract is for the same amount as the stand-alone selling price of the additional goods or services included in the modification.

We estimate variable consideration at the most likely amount to which we expect to be entitled. Any variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted) that is reasonably available to us.

We allocate variable consideration entirely to a performance obligation or to a distinct good or service within a performance obligation if it relates specifically to our efforts to satisfy the performance obligation or transfer the distinct good or service, and the allocation represents the amount of consideration to which we expect to be entitled.

Claims Against Vendors and Subcontractors

We include claims to vendors, subcontractors and others as a receivable and a reduction in recognized costs when enforceability of the claim is established by the contract and the amounts are reasonably estimable and probable of being recovered. Reductions in costs are recognized to the extent of the lesser of the amounts management expects to recover or to costs incurred.

Accounts receivable

Accounts receivable are recorded based on contracted prices when we obtain an unconditional right to payment under the terms of our contracts.

We establish an allowance for doubtful accounts based on the assessment of our clients' willingness and ability to pay. In addition to such allowances, there are often items in dispute or being negotiated that may require us to make an estimate as to the ultimate outcome. Past due receivable balances are written off when our internal collection efforts have been unsuccessful in collecting the amounts due.

Contract assets and liabilities

Billing practices are governed by the contract terms of each project based upon costs incurred, achievement of milestones or pre-agreed schedules. Billings do not necessarily correlate with revenue recognized using the cost-to-cost method of revenue recognition. Contract assets include unbilled amounts typically resulting from revenue under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to

18

payment is not unconditional. Contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue.

Retainage, included in contract assets, represents the amounts withheld from billings by our clients pursuant to provisions in the contracts and may not be paid to us until the completion of specific tasks or the completion of the project and, in some instances, for even longer periods. Retainage may also be subject to restrictive conditions such as performance guarantees.

Our contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. We classify contract liabilities as current or noncurrent based on the timing of when we expect to recognize revenue. The noncurrent portion of contract liabilities is included in "Other liabilities" in our condensed consolidated balance sheets.

Acquisition and integration related costs

Acquisition and integration related costs consist of third party transaction expenses representing legal, consulting and investment banking-related costs that are direct, incremental costs incurred prior to the closing of an acquisition and direct, incremental costs incurred to integrate the operations of newly acquired businesses into the Company's existing infrastructure as well as other initiatives to combine the newly merged companies into new infrastructure.

Note 3. Business Segment Information

We are organized into three core business segments and two non-core business segments. Our three core business segments focus on our core strengths in technical services relating to government services, technology, and hydrocarbons services. Our two non-core business segments are our Non-strategic Business segment, which includes businesses we intend to exit upon completion of existing contracts because they are no longer a part of our future strategic focus, and "Other," which includes our corporate expenses and general and administrative expenses not allocated to the other business segments. Our business segments are described below:

Government Services. Our GS business segment provides full life-cycle support solutions to defense, space, aviation and other programs and missions for military and other government agencies in the U.S., U.K. and Australia. As program management integrator, KBR covers the full spectrum of defense, space, aviation and other government programs and missions from research and development; through systems engineering, test and evaluation, systems integration and program management; to operations support, maintenance and field logistics. Our recent acquisitions, as described in Note 5 to our condensed consolidated financial statements, have been combined with our existing U.S. operations within this business segment and operate under the single "KBRwyle" brand.

Technology. Our Technology business segment combines KBR's proprietary technologies, equipment and catalyst supply and associated knowledge-based services into a global business for refining, petrochemicals, inorganic and specialty chemicals as well as gasification, syngas, ammonia, nitric acid and fertilizers. From early planning through scope definition, advanced technologies and project lifecycle support, KBR's Technology segment works closely with customers to provide the optimal approach to maximize their return on investment.

Hydrocarbons Services. Our HS business segment provides comprehensive project and program delivery capability globally. Our key capabilities leverage our operational and technical excellence as a global provider of EPC for onshore oil and gas; LNG/GTL; oil refining; petrochemicals; chemicals; fertilizers; offshore oil and gas (shallow-water, deep-water and subsea); floating solutions (FPUs, FPSO, FLNG & FSRU); maintenance services (via the “Brown & Root Industrial Services” brand); and consulting services provided under our three specialist consulting brands, Granherne, Energo and GVA.

Non-strategic Business. Our Non-strategic Business segment represents the operations or activities that we intend to exit upon completion of existing contracts. All Non-Strategic Business projects are substantially complete. We continue to finalize project close-out activities and negotiate the settlement of claims and various other matters associated with these projects.

Other. Our Other business segment includes corporate expenses and general and administrative expenses not allocated to the business segments above.

Changes in Project-related Estimates

There are many factors that may affect the accuracy of our cost estimates and ultimately our future profitability. These include, but are not limited to, the availability and costs of resources (such as labor, materials and equipment), productivity and weather, and for unit rate and construction service contracts, the availability and detail of customer supplied engineering drawings. With a portfolio of more than one thousand contracts, we sometimes realize both lower and higher than expected margins on projects in any given period. We recognize revisions of revenues and costs in the period in which the revisions are known. This may result in the recognition of costs before the recognition of related revenue recovery, if any.

Changes in project-related estimates by business segment that significantly impacted operating income were as follows:

Hydrocarbons Services

We recognized changes to equity in earnings as a result of various changes to estimates on the Ichthys LNG project during the three and nine months ended September 30, 2017. See Note 10 for a discussion of the matters impacting this project during the three and nine months ended September 30, 2018.

In the second quarter of 2018, we recognized a favorable change in estimated revenues and net income associated with variable consideration recognized as a result of successful completion and performance testing of a major Hydrocarbons Services project.

The PEMEX and PEP arbitration settlement (see Note 16 to our condensed consolidated financial statements) resulted in additional revenues and gross profit of $35 million during the nine months ended September 30, 2017.

Note 4. Revenue

We disaggregate our revenue from customers by type of service, geographic destination and contract type for each of our segments, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. See details in the tables below.

Revenue by Service/Product line was as follows:

We recognized revenue of $23 million and $54 million from performance obligations satisfied in previous periods for the three and nine month periods ended September 30, 2018, respectively.

On September 30, 2018, we had $10.1 billion of transaction price allocated to remaining performance obligations. We expect to recognize approximately 30% of our remaining performance obligations as revenue within one year, 24% in years two through five, and 46% thereafter. Revenue associated with our remaining performance obligations to be recognized beyond one year includes performance obligations related to Aspire Defence and Fasttrax projects, which have contract terms extending through 2041 and 2023, respectively. The balance of remaining performance obligations does not include variable consideration that was determined to be constrained as of September 30, 2018.

Note 5. Acquisitions, Dispositions and Other Transactions

Stinger Ghaffarian Technologies Acquisition

On April 25, 2018, we acquired 100% of the outstanding stock of Stinger Ghaffarian Technologies ("SGT"). SGT is a leading provider of high-value engineering, mission operations, scientific and IT software solutions in the government services market. We accounted for this transaction using the acquisition method under ASC 805, Business Combinations. The acquisition is reported within our GS business segment. Aggregate base consideration for the acquisition was $355 million, plus $13 million of working capital and other purchase price adjustments set forth in the purchase agreement. We initially recognized goodwill of $257 million arising from the acquisition, which primarily relates to future growth opportunities based on an expanded service offering and other expected synergies from the combined operations. Approximately $237 million of the goodwill is deductible for tax purposes. The intangible assets recognized were comprised of customer relationships and backlog. These intangibles will be amortized over a weighted-average period of 19 years. During the third quarter of 2018, we recognized an adjustment to reflect the final working capital settlement, which increased other current assets and decreased the fair value of consideration transferred by $3 million.

We funded the acquisition with borrowings under our new Senior Credit Facility that were entered into concurrently with the acquisition. See Note 13 to our condensed consolidated financial statements for information related to our new Senior Secured Credit Facility. We recognized direct, incremental costs related to this acquisition of $1 million and $4 million during the three and nine months ended September 30, 2018, respectively, which are included in "Acquisition and integration related costs" on the condensed consolidated statements of operations.

The following table summarizes the consideration paid for this acquisition and the fair value of the assets acquired and liabilities assumed as of the acquisition date.

The acquired SGT business contributed $126 million and $216 million of revenues and $12 million and $19 million of gross profit for the three and nine month periods ended September 30, 2018, respectively, within our GS business segment.

Aspire Defence Subcontracting Joint Ventures

On January 15, 2018, Carillion plc ("Carillion"), our U.K. partner in the joint ventures that provide the construction and related support services to Aspire Defence Limited, entered into compulsory liquidation. Carillion no longer performs any of the services for the project, as we have stepped in to deliver both construction and support services without disruption. In accordance with the commercial arrangements of the project company and its lenders, Carillion was excluded from future business and benefit from its interest in the project and we have assumed operational management and control of the subcontracting joint ventures.

During the first quarter of 2018, we evaluated our rights and obligations under the joint venture agreements and other commercial arrangements of the project company and its lenders. We concluded Carillion's liquidation was a reconsideration event for KBR to reevaluate the primary beneficiary of the subcontracting joint ventures in which we were partners. We concluded KBR is the primary beneficiary as it has the power to direct activities having the most significant impact on the economic performance of the subcontracting joint ventures. Consequently, KBR began consolidating these entities in its financial statements effective January 15, 2018.

25

Prior to obtaining control of these entities, we accounted for our 50% investment in each of the subcontracting joint ventures under the equity method of accounting. The balance of our net equity investments in these entities was approximately $5 million as of January 15, 2018. As a result of obtaining control of the subcontracting joint ventures, we accounted for these transactions under the acquisition method of accounting for business combinations in accordance with ASC 805. Consequently, we remeasured our equity interests in each of the subcontracting joint ventures to fair value, which resulted in a gain of approximately $113 million included in "Gain on consolidation of Aspire entities" in our condensed consolidated statements of operations. The fair value of each of the subcontracting joint ventures was determined using a discounted cash flow model with future cash flows based on internal forecasts of revenue and expenses over the remaining life of the subcontract agreements. To arrive at our future cash flows, we used estimates of economic and market assumptions, including growth rates in revenues, costs, estimates of future expected changes in operating margins, tax rates and cash expenditures. The estimated cash flows were discounted using a weighted-average cost of capital that reflected current market conditions and the risk profile for each of the subcontracting joint ventures.

We recognized goodwill of approximately $44 million, which was primarily related to the deferred tax liabilities associated with the contract-related intangible assets acquired in the transaction. None of the goodwill is deductible for tax purposes. The contract-related intangible assets have estimated useful lives ranging 4 to 23 years. During the third quarter of 2018, we made immaterial adjustments and reclassifications to the previously reported assets acquired and liabilities assumed upon obtaining control of the subcontracting joint ventures including an increase to accounts receivable of $10 million and decrease to intangible assets of approximately $9 million. Certain data necessary to complete the purchase price allocation is not yet available and primarily relates to the final tax returns that provide the underlying tax basis of the assets and liabilities. The following table summarizes the fair value of the assets acquired and liabilities assumed as of the date we obtained control of the subcontracting joint ventures.

On April 18, 2018, we completed the acquisition of Carillion's interests in the subcontracting entities for $50 million pursuant to a share and business purchase agreement and approval by Aspire Defence Limited, the Aspire Defence Limited project lenders and the MoD. We accounted for the change in KBR's interest as an equity transaction. The difference between the noncontrolling interests of $124 million in the subcontracting entities at the date of acquisition and the cash consideration paid to Carillion was recognized as a net increase to "PIC" of $74 million for the nine month period ended September 30, 2018. We incurred $0 million and $1 million of acquisition-related costs for the three and nine months ended September 30, 2018, which were recorded in "Acquisition and integration related costs" on our condensed consolidated statements of operations.

26

The results of operations of the subcontracting entities have been included in our condensed consolidated statements of operations for periods subsequent to assuming control on January 15, 2018. The acquired subcontracting joint ventures contributed $138 million and $387 million of revenues and $14 million and $42 million of gross profit for the three and nine month periods ended September 30, 2018, respectively, within our GS business segment.

The following supplemental pro forma condensed consolidated results of operations assume that SGT and the Aspire Defence subcontracting joint ventures had been acquired as of January 1, 2017. The supplemental pro forma information was prepared based on the historical financial information of SGT and the Aspire Defence subcontracting joint ventures and has been adjusted to give effect to pro forma adjustments that are both directly attributable to the transaction and factually supportable. Pro forma adjustments were primarily related to the amortization of intangibles, interest on borrowings related to the acquisitions, and the reclassification of the gain on consolidation of the Aspire entities to January 1, 2017. Accordingly, this supplemental pro forma financial information is presented for informational purposes only and is not necessarily indicative of what the actual results of operations of the combined company would have been had the acquisitions occurred on January 1, 2017, nor is it indication of future results of operations.

Sigma Bravo Pty Ltd Acquisition

During the fourth quarter of 2017, we acquired 100% of the outstanding common shares of Sigma Bravo Pty Ltd ("Sigma Bravo"). Sigma Bravo provides information management, technical support and training services as well as operational support to the Australian Defence Force.

The aggregate purchase price of the acquisition was $9 million. We recognized goodwill of $1 million arising from the acquisition, which relates primarily to customer relationships and future growth opportunities to expand services provided to the Australian Defence Force. None of the goodwill is deductible for income tax purposes. The final settlement of the working capital adjustment occurred in the second quarter of 2018 and did not have a material effect on our condensed consolidated financial statements. In the third quarter of 2018, we recorded a deferred tax liability and corresponding increase to goodwill of approximately $2 million associated with the acquired intangible assets.

Subsequent Event

On October 11, 2018 we sold our interest in our EPIC joint venture for approximately $24 million. As of September 30, 2018, our balance in "Equity in and advances to unconsolidated affiliates" associated with this joint venture was approximately $24 million.

Note 6. Cash and Equivalents

We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and equivalents include cash balances held by our wholly owned subsidiaries as well as cash held by joint ventures that we consolidate. Joint venture and the Aspire project cash balances are limited to specific project activities and are not available for other projects, general cash needs or distribution to us without approval of the board of directors of the respective entities. We expect to use this cash for project costs and distributions of earnings. However, some of the earnings distributions may be paid to other KBR entities where the cash can be used for general corporate needs.

The components of our cash and equivalents balance are as follows:

	September 30, 2018
Dollars in millions	International (a)		Domestic (b)		Total
Operating cash and equivalents	$	153	$	79	$	232
Short-term investments (c)	17		29		46
Cash and equivalents held in consolidated joint ventures and Aspire Defence subcontracting entities	301		2		303
Total	$	471	$	110	$	581

	December 31, 2017

Operating cash and equivalents	$	112	$	124	$	236
Short-term investments (c)	82		60		142
Cash and equivalents held in consolidated joint ventures	59		2		61
Total	$	253	$	186	$	439

(a) Includes deposits held in non-U.S. operating accounts.

(b) Includes U.S. dollar and foreign currency deposits held in operating accounts that constitute onshore cash for tax purposes but may reside either in the U.S. or in a foreign country.

(c) Includes time deposits, money market funds, and other highly liquid short-term investments.

Note 7. Accounts Receivable

The components of our accounts receivable, net of allowance for doubtful accounts balance, are as follows:

	September 30, 2018
Dollars in millions	Unbilled		Trade & Other		Total
Government Services	$	232	$	295	$	527
Technology	6		65		71

Subtotal	314		552		866
Non-strategic Business	—		—		—
Total	$	314	$	552	$	866

As a result of the adoption of ASC 606 on January 1, 2018, unbilled accounts receivable is classified in "Accounts receivable" in our condensed consolidated balance sheets as it represents the amounts that have been recorded in revenue based on contracted prices for which we have obtained an unconditional right to payment under the terms of our contracts. Retainage is now recorded in "Contract Assets" in our condensed consolidated balance sheets when the right to payment of the retainage is conditional under the terms of our contracts. Prior to the adoption of ASC 606, unbilled accounts receivables were classified as "Costs and estimated earnings in excess of billings on uncompleted contracts" and retainage was classified within "Accounts receivable".

	December 31, 2017
Dollars in millions	Retainage		Trade & Other		Total

Note 8. Contract Assets and Contract Liabilities

The timing of revenue recognition, billings and cash collections results in accounts receivable, contract assets, and contract liabilities on the condensed consolidated balance sheets.

Our contract assets by business segment are as follows:

	September 30,		December 31,
Dollars in millions	2018		2017		$ Change			% Change
Government Services	$	118	$	274	$	(156	)	(57	)%
Technology	25		39		(14		)	(36	)%
Hydrocarbons Services	71		70		1			1	%
Subtotal	214		383		(169		)	(44	)%
Non-strategic Business	—		—		—			N/A
Total	$	214	$	383	$	(169	)	(44	)%

The decrease in contract assets was primarily caused by the initial adjustment due to the adoption of ASC 606, offset by normal business operations and the acquisition of $21 million of contract assets from the purchase of SGT as described in Note 5 to our condensed consolidated financial statements.

Our contract liabilities by business segment are as follows:

	September 30,		December 31,
Dollars in millions	2018		2017		$ Change		% Change
Government Services	$	240	$	85	155		182	%
Technology	101		62		39		63	%
Hydrocarbons Services	118		213		(95	)	(45	)%
Subtotal	459		360		99		28	%
Non-strategic Business	5		8		(3	)	(38	)%
Total	$	464	$	368	96		26	%

The increase in contract liabilities was primarily related to the acquisition of $161 million of contract liabilities associated with the Aspire Defence project joint ventures, partially offset by normal business operations and the recognition of the incentive fee associated with an Australian LNG project.

Revenue recognized for the nine months ended September 30, 2018 that was included in the contract liability balance at December 31, 2017 was $247 million.

Note 9. Claims and Accounts Receivable

Our claims and accounts receivable balance not expected to be collected within the next 12 months was $96 million and $101 million as of September 30, 2018 and December 31, 2017, respectively. Claims and accounts receivable primarily reflects claims filed with the U.S. government related to payments not yet received for costs incurred under various U.S. government cost reimbursable contracts within our GS business segment. These claims relate to disputed costs or contracts where our costs have exceeded the U.S. government's funded value on the task order. Included in the amount is $73 million as of September 30, 2018 and $79 million as of December 31, 2017, respectively, related to Form 1s issued by the U.S. government questioning or objecting to costs billed to them. See Note 15 of our condensed consolidated financial statements for additional information. The amount also includes $23 million and $22 million as of September 30, 2018 and December 31, 2017, respectively, related to contracts where our reimbursable costs have exceeded the U.S. government's funded values on the underlying task orders or task orders where the U.S. government has not authorized us to bill. We believe the remaining disputed costs will be resolved in our favor, at which time the U.S. government will be required to obligate funds from appropriations for the year in which resolution occurs.

Note 10. Unapproved Change Orders, Claims, and Estimated Recoveries of Claims Against Suppliers and Subcontractors

The amounts of unapproved change orders, claims and estimated recoveries of claims against suppliers and subcontractors included in determining the profit or loss on contracts are as follows:

Dollars in millions	2018			2017
Amounts included in project estimates-at-completion at January 1,	$	924		$	294
Increase (decrease), including foreign currency effect	39			483
Approved change orders	(4		)	(4		)
Amounts included in project estimates-at-completion at September 30,	$	959		$	773
Amounts recognized over time based on progress at September 30,	$	922		$	687

As of September 30, 2018, the predominant component of the change orders, customer claims and estimated recoveries of claims against suppliers and subcontractors above relates to our proportionate share of unapproved change orders and claims associated with the Ichthys LNG Project discussed below.

KBR intends to vigorously pursue approval and collection of amounts still due under all unapproved change orders and claims, as well as resolution of contingencies within reserved amounts with subcontractors and clients. Further, there are additional claims that KBR believes it is entitled to recover from its clients and from subcontractors which have been excluded from estimated revenues and profits at completion as appropriate under U.S. GAAP. These commercial matters may not be resolved in the near term. Our current estimates for the above unapproved change orders, customer claims and estimated recoveries of claims against suppliers and subcontractors may prove inaccurate and could result in significant changes to the estimated revenues, costs and profits at completion on the underlying projects.

Ichthys LNG Project

Project Status

We have a 30% ownership interest in the JKC joint venture ("JKC"), which has contracted to perform the engineering, procurement, supply, construction and commissioning of onshore LNG facilities for a client in Darwin, Australia (the "Ichthys LNG Project"). The contract between JKC and its client is a hybrid contract containing both cost-reimbursable and fixed-price (including unit-rate) scopes.

The Ichthys LNG Project is substantially complete on a cost-to-cost basis. All of the components of the plant, except for the combined cycle power plant ("Power Plant"), have been completed and handed over to the client. The Power Plant includes five gas turbine generators which are complete and handed over to the client, and three steam turbine generators (the "STGs") which are currently forecasted to be completed by the end of the second quarter 2019. At the current level of progress, which includes portions of the power plant already completed, the plant is capable of LNG production.

Unapproved Change Orders and Claims

JKC has entered into commercial contracts with multiple suppliers and subcontractors to execute various scopes of work on the project. Certain of these suppliers and subcontractors have made contract claims against JKC for recovery of costs and extensions of time in order to progress the works under the scope of their respective contracts due to a variety of issues related to changes to the scope of work, delays and lower than planned subcontractor productivity. In addition, JKC has incurred costs related to scope increases and other factors, and has made claims to its client for matters for which JKC believes reimbursement is entitled under the contract.

JKC believes any amounts paid or payable to the suppliers and subcontractors in settlement of their contract claims related to cost-reimbursable scope are an adjustment to the contract price, and accordingly JKC has made claims for contract price adjustments under the reimbursable portion of the contract between JKC and its client. However, the client disputed some of these contract price adjustments and subsequently withheld certain payments. In order to facilitate the continuation of work under the contract while we worked to resolve this dispute, the client agreed to a contractual mechanism (“Funding Deed”) in 2016 providing funding in the form of an interim contract price adjustment to JKC and consented to settlement of subcontractor claims as of that date related to the cost-reimbursable scope. While the client reserved its rights under this funding mechanism, settlement funds (or interim contract price adjustment) have been paid by the client. JKC in turn settled these subcontractor claims which have been funded through the Funding Deed by the client.

30

If JKC's claims against its client which were funded under the Funding Deed remain unresolved by December 31, 2020, JKC will be required to refund sums funded by the client under the terms of the Funding Deed. We, along with our joint venture partners, are jointly and severally liable to the client for any amounts required to be refunded. While JKC continued to pursue settlement of these disputes with the client, JKC initiated arbitration proceedings in 2017 and is planning other arbitrations against the client to resolve open claims.

Our proportionate share of the total amount of the contract price adjustments under the Funding Deed included in the unapproved change orders and claims related to our unconsolidated affiliates discussed above is $163 million and $177 million as of September 30, 2018 and December 31, 2017, respectively. The difference in these values is strictly due to exchange rate fluctuations.

In September and October 2017, additional settlements pertaining to suppliers and subcontractors under the cost reimbursable portion of the contract were presented to the client. The client consented to these settlements and paid for them but reserved its rights. In reliance, JKC in turn settled these claims with the associated suppliers and subcontractors. The formal contract price adjustments for these settlements remained pending at September 30, 2018, but unlike amounts funded under the Funding Deed, there is no requirement to refund these amounts to the client by a date certain.

In October 2018, JKC received a favorable ruling from an arbitration tribunal. The ruling determined a contract interpretation in JKC's favour, to the effect that delay and disruption costs payable to subcontractors under the cost-reimbursable scope of the EPC contract are for the client's account. JKC contends this ruling resolves the reimbursability of the subcontractor settlement sums under the Funding Deed and additional settlements made in September and October 2017.  Pursuant to this decision, JKC is undertaking steps for a formal contract adjustment to the reimbursable portion of the contract for these settlement claims of which $332 million are included in the recognized unapproved change orders as of September 30, 2018.

There has been deterioration of paint on certain exterior areas of the plant. The client has requested, and has funded, paint remediation for a portion of the facilities. The client has requested a remediation plan for the remainder of the facilities, but JKC and its client have not resolved who is responsible for the paint defects and the manner in which it is to be remediated. JKC’s profit estimate at completion includes those revenues and costs for remediation activities that it has been directed to perform and are being funded by the client. JKC has also started proceedings against the paint manufacturer and made demands on insurance related to these issues.

As discussed above, the additional costs associated with these various claims and related issues have been included in determining estimated profit at completion. Estimated recoveries associated with the additional change orders, customer claims, and claims against suppliers and subcontractors have also been included in determining estimated profit at completion. Our current estimates for the above unapproved change orders and customer claims may prove inaccurate and could result in significant changes to the estimated revenue, costs and profits at completion on the underlying projects.

Other Matters

JKC is entitled to an amount of profit and overhead (“TRC Fee”) which is a fixed percentage of the target reimbursable costs ("TRC") under the reimbursable component of the contract which was to be agreed by JKC and its client. At the time of the contract, JKC and its client agreed to postpone the fixing of the TRC until after a specific milestone in the project had been achieved. Although the milestone was achieved, JKC and its client have been unable to reach agreement on the TRC. This matter was taken to arbitration in 2017. A decision was issued in December 2017 which provided some further basis for determination of the TRC amount and the TRC Fee. JKC has included an estimate for the TRC Fee in its determination of profit at completion at December 31, 2017 based on the contract provisions and the decision from the December 2017 arbitration and terms of the EPC contract with the client. JKC has submitted the revised estimate of the TRC Fee to the client. The parties have not agreed the revised estimate.

If the above matters are not resolved with the client for the amounts recorded, or to the extent JKC is unsuccessful in retaining amounts paid to it under the Funding Deed and other funding mechanisms used by the client, we would be responsible for our pro-rata portion of any additional costs and refunded sums in excess of the final adjusted contract price, which could have a material adverse effect on our results of operations, financial position and cash flows. Additionally, to the extent the client does not provide adequate and proper funding for project activities prior to resolution of these matters, the joint venture partners will be required to fund working capital requirements of JKC in the near term which could have a material adverse effect on our financial position and cash flows.

Combined Cycle Power Plant

31

Pursuant to JKC's fixed-price scope of its contract with its client, JKC awarded a fixed-price EPC contract to a subcontractor for the design, construction and commissioning of a combined cycle power plant. The subcontractor was a consortium consisting of General Electric and GE Electrical International Inc. and a joint venture between UGL Infrastructure Pty Limited and CH2M Hill (collectively, the "Consortium"). On January 25, 2017, JKC received a Notice of Termination from the Consortium, and the Consortium ceased work on the Power Plant and abandoned the construction site. JKC believes the Consortium materially breached its subcontract and repudiated its obligation to complete the Power Plant, plus undertook actions making it more difficult and more costly for the works to be completed by others after the Consortium abandoned the site. Subsequently, the Consortium filed a request for arbitration with the ICC asserting that JKC repudiated the contract. The Consortium also sought an order that the Consortium validly terminated the subcontract. JKC has responded to this request, denying JKC committed any breach of its subcontract with the Consortium and restated its claim that the Consortium breached and repudiated its subcontract with JKC and is furthermore liable to JKC for all costs to complete the Power Plant.

JKC prevailed in a legal action against the Consortium requiring the return of materials, drawings and tools following their unauthorized removal from the site. JKC discovered incomplete and defective engineering designs, defective workmanship on the site, missing, underreported and defective materials; and the improper termination of key vendors/suppliers. JKC's investigations also indicate that progress of the work claimed by the Consortium was over-reported. JKC has evaluated the cost to complete the Consortium's work, which significantly exceeds the awarded fixed-price subcontract value. JKC's cost to complete the Power Plant includes re-design efforts, additional materials and significant re-work. These costs represent estimated recoveries of claims against the Consortium and have been included in JKC's estimate to complete the Consortium's remaining obligations.

JKC is pursuing recourse against the Consortium to recover all of the costs to complete the Power Plant, plus the additional interest, and/or general damages by all means inclusive of calling bank guarantees provided by the Consortium partners. In April 2018, JKC prevailed in its legal action to call the bank guarantees (bonds) and subsequently called the bonds of two of the Consortium members, receiving funds totaling $52 million. Each of the Consortium partners has joint and several liability with respect to all obligations under the subcontract. JKC intends to pursue recovery of all additional amounts due from the Consortium via various legal remedies available to JKC.

Estimated costs to complete the Power Plant that have been determined to be probable of recovery from the Consortium under U.S. GAAP have been included as a reduction of cost in our estimate of profit at completion. The estimated recoveries exclude interest, liquidated damages and other related costs which JKC intends to pursue recovery from the Consortium.

As of September 30, 2018, JKC estimated claims against the Consortium were approximately $1.9 billion for recovery of these expected costs. The arbitration is likely to be set for hearing in the first half of 2020. JKC has also recently initiated suits against the parent companies of the Consortium members based on their payment and performance guarantees.

To the extent JKC is unsuccessful in prevailing in the Arbitration or the Consortium members are unable to satisfy their financial obligations in the event of a decision favorable to JKC, we would be responsible for our pro-rata portion of unrecovered costs from the Consortium. This could have a material adverse impact on the profit at completion of the overall contract and thus on our consolidated statements of operations, financial position and cash flow. Additionally, to the extent JKC does not resolve this matter with the Consortium in the near term, the joint venture partners have been and will continue to be required to fund JKC's completion of the combined cycle power plant which could have a material adverse effect on our financial position and cash flows. Further, if our partners in JKC do not fulfill their obligations under the subcontract, we could be exposed to the full amount of those funding requirements and potential losses as a result of the nature of the JKC JV agreement.

Ichthys Project Funding

JKC has recorded significant unapproved change orders and claims with the client as well as estimated recoveries of claims against suppliers and subcontractors arising from issues related to changes to the work scope, delays and lower than planned subcontractor activity discussed above. As a result of the ongoing disputes with the client and pursuit of recoveries against the Consortium through arbitration, additional contributions from the JKC joint venture partners are required to fund the project. During the nine months ended September 30, 2018, we made investment contribution to JKC of approximately $257 million to fund our proportionate share of the ongoing project execution activities. Our estimate of additional investment contributions increased by $100 million to approximately $250 million to complete the project, excluding future recoveries of claims and unapproved change orders.

32

Liquidated damages

Some of our hydrocarbons services contracts have schedule dates and performance obligations that, if not met, could subject us to penalties for liquidated damages. These generally relate to specified activities that must be completed by a set contractual date or by achievement of a specified level of output or throughput. Each contract defines the conditions under which a customer may make a claim for liquidated damages. However, in some instances, liquidated damages are not asserted by the customer, but the potential to do so is used in negotiating or settling claims and closing out the contract. Any accrued liquidated damages are recognized as a reduction in revenues in our condensed consolidated statements of operations.

In addition to the accrued liquidated damages, it is possible that liquidated damages that have not been included in our estimates at completion in determining project income related to several projects totaling $9 million and $9 million at September 30, 2018 and December 31, 2017, respectively, could be incurred if the projects are completed as currently forecasted. However, based upon our evaluation of our performance and other mitigating factors, we have concluded these liquidated damages are not probable.

Note 11. Equity Method Investments and Variable Interest Entities

We conduct some of our operations through joint ventures, which operate through partnership, corporation, undivided interest and other business forms and are principally accounted for using the equity method of accounting. Additionally, the majority of our joint ventures are VIEs.

The following table presents a rollforward of our equity in and advances to unconsolidated affiliates:

	September 30,			December 31,
Dollars in millions	2018			2017
Beginning balance	$	387		$	369
Cumulative effect of change in accounting policy (a)	87			—
Adjusted balance at January 1, 2018	474			369
Equity in earnings of unconsolidated affiliates	54			72
Distribution of earnings of unconsolidated affiliates (b)	(16		)	(62		)
Advances (receipts)	(7		)	(11		)
Investments (c)	257			—
Foreign currency translation adjustments	(19		)	12
Other	(19		)	5
Balance before reclassification	$	724		$	385
Reclassification of excess distributions (b)	—			11
Recognition of excess distributions (b)	—			(9		)
Ending balance	$	724		$	387

(a) As further discussed in Note 1 to our condensed consolidated financial statements, deferred construction income in the amount of $87 million previously recorded in "Equity in and advance to unconsolidated affiliates" was reversed and included in the cumulative effect adjustment as a result of the early adoption of ASC 606 by the Aspire Defence project joint ventures.

(b) From 2014 through 2017, we received cash dividends in excess of the carrying value of one of our unconsolidated joint ventures. We have no obligation to return any portion of the cash dividends received. We recorded excess dividends as "Deferred income from unconsolidated affiliates" on our condensed consolidated balance sheets and recognized these dividends as earnings are generated by the investment. As further discussed in Note 1 to our condensed consolidated financial statements, the adoption of ASC Topic 606 by this unconsolidated joint venture resulted in the reversal of the "Deferred income from unconsolidated affiliates" balance of $101 million in our condensed consolidated balance sheets as of December 31, 2017 in the cumulative effect adjustment of the change in accounting policy.

(c) In 2018, investments included a $257 million investment to fund JKC.

33

Unconsolidated Variable Interest Entities

For the VIEs in which we participate, our maximum exposure to loss consists of our equity investment in the VIE and any amounts owed to us for services we may have provided to the VIE, reduced by any unearned revenues on the project. Our maximum exposure to loss may also include our obligation to fund our proportionate share of any future losses incurred. As of September 30, 2018, we do not project any losses related to these joint venture projects. Where our performance and financial obligations are joint and several to the client with our joint venture partners, we may be further exposed to losses above our ownership interest in the joint venture.

The following summarizes the total assets and total liabilities as reflected in our condensed consolidated balance sheets related to our unconsolidated VIEs in which we have a significant variable interest but are not the primary beneficiary. Amount disclosed as Aspire Defence entities for 2017 reflect both contracting and subcontracting entities related to the Aspire Defence project.

	September 30, 2018
Dollars in millions	Total assets		Total liabilities
Affinity joint venture (U.K. MFTS project)	$	15	$	3
Aspire Defence contracting entities	$	80	$	6
JKC joint venture (Ichthys LNG project)	$	376	$	29

Related Party Transactions

We often provide engineering, construction management and other subcontractor services to our joint ventures and our revenues include amounts related to these services. For the nine months ended September 30, 2018 and 2017, our revenues included $145 million and $85 million, respectively, related to the services we provided to our joint ventures, primarily the Ichthys JV within our HS business segment. Under the terms of an alliance agreement with our EPIC joint venture, EPIC provides certain pipe fabrication services to KBR. EPIC provided no services to KBR under the agreement in the nine months ended September 30, 2018 and $3 million of services to KBR under the agreement in the nine months ended September 30, 2017.

Under the terms of our TSA with Brown & Root Industrial Services joint venture, we collect cash from customers and make payments to vendors and employees on behalf of the joint venture. For the nine months ended September 30, 2018 and 2017, we incurred approximately $2 million and $4 million, respectively, of reimbursable costs under the TSA.

Amounts included in our condensed consolidated balance sheets related to services we provided to our unconsolidated joint ventures as of September 30, 2018 and December 31, 2017 are as follows:

Senior Credit Facility

On April 25, 2018, the Company refinanced its $1 billion Credit Agreement due September 2020 (our "Credit Agreement"). The new senior secured credit facility ("Senior Credit Facility") consists of a $500 million revolving credit facility ("Revolver"), a $500 million performance letter of credit facility ("PLOC"), a $350 million Delayed Draw Term Loan A, ("Term Loan A") and an $800 million Term Loan B ("Term Loan B"). The Revolver, PLOC and Term Loan A mature in April 2023 and the Term Loan B matures in April 2025. The Term Loan A may be drawn upon until the earlier of becoming fully drawn or June 30, 2019 (the "Availability Period"). Borrowings under the Term Loan A may only be used to fund investments in JKC. See Note 10 to our condensed consolidated financial statements for a discussion on JKC.

36

The interest rate with respect to the Term Loan B is LIBOR plus 3.75%. The interest rates with respect to the Revolver and Term Loan A are based on, at the Company's option, adjusted LIBOR plus an additional margin or base rate plus additional margin. The Senior Credit Facility provides for fees on letters of credit issued under the PLOC at varying rates, as shown below. Additionally, there is a commitment fee with respect to the Revolver, PLOC and Term Loan A. The details of the applicable margins and commitment fees are based on the Company's consolidated leverage ratio as follows:

	Revolver and Term Loan A
Consolidated Leverage Ratio	LIBOR Margin		Base Rate Margin		Performance Letter of Credit Fee		Commitment Fee
Greater than or equal to 4.00 to 1.00	3.25	%	2.25	%	1.95	%	0.450	%
Less than 4.00 to 1.00 but greater than or equal to 3.00 to 1.00	3.00	%	2.00	%	1.80	%	0.400	%
Less than 3.00 to 1.00 but greater than or equal to 2.00 to 1.00	2.75	%	1.75	%	1.65	%	0.375	%
Less than 2.00 to 1.00	2.50	%	1.50	%	1.50	%	0.350	%

The Term Loan A provides for quarterly principal payments of 2.50% of the aggregate principal amount commencing with the fiscal quarter ending June 30, 2019. The Term Loan B provides for quarterly principal payments of 0.25% of the initial aggregate principal amounts commencing with the fiscal quarter ending September 30, 2018.

The Senior Credit Facility contains customary restrictive covenants, subject to certain permitted amounts and exceptions, including covenants limiting our ability to incur additional liens and indebtedness, enter into asset sales, repurchase our equity shares and make certain types of investments.

The Revolver, PLOC, and Term Loan A contain financial maintenance covenants of a maximum consolidated leverage ratio and a consolidated interest coverage ratio (as such terms are defined in the Senior Credit Facility). Our consolidated leverage ratio as of the last day of any fiscal quarter, commencing with the fiscal quarter ending June 30, 2018, may not exceed 4.50 to 1 and reducing gradually during 2019 and 2020 to 3.50 to 1. Our consolidated interest coverage ratio as of the last day of any fiscal quarter, commencing with the fiscal quarter ending June 30, 2018 and thereafter, may not be less than 3.00 to 1. As of September 30, 2018, we were in compliance with our financial covenants.

Nonrecourse Project Debt

Fasttrax Limited, a joint venture in which we indirectly own a 50% equity interest with an unrelated partner, was awarded a concession contract in 2001 with the U.K. MoD to provide a Heavy Equipment Transporter Service to the British Army. Under the terms of the arrangement, Fasttrax Limited operates and maintains 91 HETs for a term of 22 years. The purchase of the HETs by the joint venture was financed through two series of bonds secured by the assets of Fasttrax Limited and a bridge loan totaling approximately £84.9 million (approximately $120 million at the exchange rate on the date of the transaction). The secured bonds are an obligation of Fasttrax Limited and are not a debt obligation of KBR as they are nonrecourse to the joint venture partners. Accordingly, in the event of a default on the notes, the lenders may only look to the assets of Fasttrax Limited for repayment. The bridge loan of approximately £12.2 million (approximately $17 million at the exchange rate on the date of the transaction) was replaced when we and the other joint venture partners funded the joint venture with equity and subordinated notes in 2005.

The secured bonds were issued in two classes consisting of Class A 3.5% Index Linked Bonds in the amount of £56 million (approximately $79 million at the exchange rate on the date of the transaction) and Class B 5.9% Fixed Rate Bonds in the amount of £16.7 million (approximately $24 million at the exchange rate on the date of the transaction).  Semi-annual payments on both classes of bonds commenced in March 2005 and will continue through maturity in 2021.  The subordinated notes payable to each of the partners initially bear interest at 11.25% increasing to 16% over the term of the notes until maturity in 2025.  Semi-annual payments on the subordinated notes commenced in March 2006. For financial reporting purposes, the portion of the subordinated notes payable to us is eliminated in consolidation and consequently, only our partner's portion of the subordinated notes appears in the condensed consolidated financial statements.

Note 14. Income Taxes

Our estimated annual effective tax rate for 2018 is 23% including the discrete tax impact of obtaining control of the Aspire Defence subcontracting joint ventures that was recorded at a lower rate than our estimated annual tax rate for 2018. The effective tax rate was approximately 28% and 22% for the three and nine months ended September 30, 2018, respectively. The effective

37

tax rate was approximately 24% and 23% for the three and nine months ended September 30, 2017, respectively. Income taxes for the three months ended September 30, 2018 were adversely impacted by newly issued interpretations from the IRS related to the Tax Cuts and Jobs Act and their cumulative impact to January 1, 2018.

On December 22, 2017, the U.S. enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act") making broad and complex changes to the U.S. tax code. SEC Staff Accounting Bulletin (SAB) 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In January, April, and August of 2018, the Internal Revenue Service ("IRS") issued guidance and proposed regulations which provides additional clarification on certain aspects of the Deemed Repatriation Transition Tax ("Transition Tax") calculation. We applied this guidance which impacted certain tax elections, increasing our estimated Transition Tax liability to approximately $227 million which was fully offset by foreign tax credits generated by the deemed repatriation as well as foreign tax credit carryforwards available for use. We anticipate additional IRS guidance relative to Transition Tax and other aspects of the Tax Act to be forthcoming throughout the remainder of 2018. As of September 30, 2018, we have not yet completed our tax accounting for the income tax effects of the Tax Act and will continue to revise our provisional amounts as additional guidance becomes available. The Company expects to complete our accounting within the prescribed measurement period.

Our estimated annual effective rate is subject to change based on the actual jurisdictions where our 2018 earnings are generated and further guidance issued by the IRS.

The valuation allowance for deferred tax assets as of September 30, 2018 and December 31, 2017 was $145 million and $217 million, respectively. The change in the valuation allowance was a decrease of $4 million and decrease of $11 million for the three months ended September 30, 2018 and 2017, respectively, and a decrease of $72 million and decrease of $30 million for the nine months ended September 30, 2018 and 2017, respectively. The decrease in valuation allowance primarily related to changes in foreign tax credit carryforwards due to the refinement of provisional impacts recorded related to the Transition Tax. The valuation allowance is primarily related to foreign tax credit carryforwards and foreign and state net operating loss carryforwards that, in the judgment of management, are not more likely than not to be realized. The ultimate realization of deferred tax assets is dependent on the generation of future taxable income, in the appropriate character and source, during the periods in which those temporary differences become deductible or within the remaining carryforward period. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income and tax-planning strategies in making this assessment.

The provision for uncertain tax positions included in "Other liabilities" and "Deferred income taxes" on our condensed consolidated balance sheets as of September 30, 2018 and December 31, 2017 was $97 million and $184 million, respectively. The reduction in the provision for uncertain tax positions of approximately $8 million for the three months ended September 30, 2018 reflects the release of provisions associated with the effective settlement of an audit with tax authorities as well as the expiration of statute of limitations, partially offset by a provision due to a change in measurement of a tax position as a result of an ongoing appeals process. Additionally, the change in the provision for uncertain tax positions for the nine months ended September 30, 2018 contains a settlement with a tax authority, resulting in a write off of the deferred tax asset that previously had an uncertain tax position liability recorded against it, and consequently had no impact on tax expense.

Note 15. U.S. Government Matters

We provide services to various U.S. governmental agencies, which include the U.S. DoD, NASA, and the Department of State. We may have disagreements or experience performance issues on our U.S. government contracts. When performance issues arise under any of these contracts, the U.S. government retains the right to pursue various remedies, including challenges to expenditures, suspension of payments, fines and suspensions or debarment from future business with the U.S. government. The negotiation, administration and settlement of our contracts are subject to audit by the DCAA. The DCAA serves in an advisory role to the DCMA, and the DCMA is responsible for the administration of the majority of our contracts. The scope of these audits include, among other things, the validity of direct and indirect incurred costs, provisional approval of annual billing rates, approval of annual overhead rates, compliance with the FAR and CAS, compliance with certain unique contract clauses and audits of certain aspects of our internal control systems. Based on the information received to date, we do not believe the completed or ongoing government audits will have a material adverse impact on our results of operations, financial position or cash flows.

Legacy U.S. Government Matters

Between 2002 and 2011, we provided significant support to the U.S. Army and other U.S. government agencies in support of the war in Iraq under the LogCAP III contract. We have been in the process of closeout of the LogCAP III contract since 2011, and we expect the closeout process to continue through at least 2019. As a result of our work under LogCAP III, there are claims

38

and disputes pending between us and the U.S. government which need to be resolved in order to close the contract. The closeout process includes resolving objections raised by the U.S. government through a billing dispute process referred to as Form 1s and MFRs. We continue to work with the U.S. government to resolve these issues and are engaged in efforts to reach mutually acceptable resolution of these outstanding matters. However, for certain of these matters, we have filed claims with the ASBCA or the COFC. We also have matters related to ongoing litigation or investigations involving U.S. government contracts. We anticipate billing additional labor, vendor resolution and litigation costs as we resolve the open matters. At this time, we cannot determine the timing or net amounts to be collected or paid to close out these contracts.

Form 1s

The U.S. government has issued Form 1s questioning or objecting to costs we billed to them under cost reimbursable contracts primarily related to our use of private security and our provision of containerized housing under the LogCAP III contract discussed below. As a consequence of the issuance of the Form 1s, the U.S. government has withheld payment to us on outstanding invoices, pending resolution of these matters.

The U.S. government has issued and has outstanding Form 1s questioning $134 million of billed costs as of September 30, 2018. They had previously paid us $61 million of the questioned costs related to our services on these contracts. The remaining balance of $73 million as of September 30, 2018 is included on our condensed balance sheet in “Claims and accounts receivable". In addition, we have withheld $26 million from our subcontractors at September 30, 2018 related to these questioned costs, which is included in "Other current liabilities" on our condensed balance sheet.

While we continue to believe that the amounts we have invoiced the U.S. government are in compliance with our contract terms and that recovery is probable, we also continue to evaluate our ability to recover these amounts as new information becomes known. As is common in the industry, negotiating and resolving these matters is often an involved and lengthy process, which sometimes necessitates the filing of claims or other legal action as discussed above. Concurrent with our continued negotiations with the U.S. government, we await the rulings on the filed claims. We are unable to predict when the rulings will be issued or when the matters will be settled or resolved with the U.S. government.

As a result of the Form 1s, and claims discussed above as well as open audits, we have accrued a reserve for unallowable costs of $32 million and $51 million, at September 30, 2018 and December 31, 2017, respectively. The balance at September 30, 2018 is recorded in "Contract liabilities" and "Other liabilities" in the amounts of $17 million and $15 million, respectively. The balance at December 31, 2017 is recorded in "Contract liabilities" and "Other liabilities" in the amounts of $31 million and $20 million, respectively.

Private Security Contractors. Starting in February 2007, we received a series of Form 1s from the DCAA informing us of the U.S. government's intent to deny reimbursement to us under the LogCAP III cost reimbursable contract for amounts related to the use of PSCs by KBR and a subcontractor in connection with its work for KBR providing dining facility services in Iraq between 2003 and 2006. The government challenged $56 million in billings. The government had previously paid $11 million and has withheld payments of $45 million, which as of September 30, 2018 we have recorded as due from the government related to this matter in "Claims and accounts receivable" on our condensed consolidated balance sheets.

On June 16, 2014, we received a decision from the ASBCA which agreed with KBR's position (i) that the LogCAP III contract did not prohibit the use of PSCs to provide force protection to KBR or subcontractor personnel, (ii) that there was a need for force protection and (iii) that the costs were reasonable. The ASBCA also found that the Army breached its obligation to provide force protection. Accordingly, we believe that we are entitled to reimbursement by the Army for the amounts charged by our subcontractors, even if they incurred costs for PSCs. The Army appealed the decision.

On June 12, 2017, we received a second ruling from the ASBCA that we are entitled to recover the withheld costs in the approximate amount of $45 million plus interest related to the use of PSCs. The Army filed a notice of appeal on October 12, 2017 and filed its brief on April 10, 2018. We responded and the Army filed its final brief in June. Oral arguments are expected to occur later this year. At this time, we believe the likelihood that we will incur a loss related to this matter is remote, and therefore we have not accrued any loss provisions related to this matter.

Investigations, Qui Tams and Litigation

The following matters relate to ongoing litigation or federal investigations involving U.S. government contracts. Many of these matters involve allegations of violations of the FCA, which prohibits in general terms fraudulent billings to the U.S. government. Suits brought by private individuals are called "qui tams." We believe the costs of litigation and any damages that may be awarded in the FKTC and Burn Pit matters described below are billable under the LogCAP III. All costs billed under LogCAP III are subject to audit by the DCAA for reasonableness.

First Kuwaiti Trading Company arbitration. In April 2008, FKTC, one of our LogCAP III subcontractors providing housing containers, filed for arbitration with the American Arbitration Association all its claims under various LogCAP III subcontracts. After complete hearings on all claims, the arbitration panel awarded FKTC $17 million plus interest for claims involving damages on lost or unreturned vehicles. In addition, we determined that we owe FKTC $32 million in connection with other subcontracts. We previously paid FKTC $19 million and have recorded $4 million in "Accounts payable" that will be paid on pay-when-paid terms in the contract. The remaining $26 million owed to FKTC under the contract has not been billed to the government and we will not do so until the related claims and disputes between KBR and the government over the FKTC living container contract are resolved (see KBR Contract Claim on FKTC containers below). This amount has been withheld from our subcontractors as described above and also recorded in "Claims and accounts receivable" on our condensed balance sheet as of September 30, 2018. At this time, we believe the likelihood that we would incur a loss related to this matter in excess of the amounts we have accrued is remote.

Burn Pit litigation. Since November 2008, KBR has been served with more than 60 lawsuits in various states alleging exposure to toxic materials resulting from the operation of burn pits in Iraq or Afghanistan in connection with services provided by KBR under the LogCAP III contract. These suits were consolidated in U.S. Federal District Court in Greenbelt, Maryland. The plaintiffs claimed unspecified damages. On January 13, 2017, KBR filed a renewed motion to dismiss and for summary judgment.

On July 19, 2017, the trial court issued its ruling granting KBR’s motions to dismiss on jurisdictional ground and for summary judgment.  In lengthy fact findings, the trial court concluded that the military made all the relevant decisions about the use, location and operation of burn pits.  The plaintiffs filed a notice of appeal, which was denied on June 20, 2018 by the Fourth Circuit Court of Appeals. The plaintiffs filed an application for writ of certiorari to the U.S. Supreme Court on September 7, 2018. We are awaiting the U.S. Supreme Court's decision as to whether it will deny the application or request further briefing. At this time, we believe the likelihood that we would incur a loss related to this matter is remote. As of September 30, 2018, no amounts have been accrued.

Howard qui tam. In March 2011, Geoffrey Howard and Zella Hemphill filed a complaint in the U.S. District Court for the Central District of Illinois alleging that KBR mischarged the U.S. government $628 million for unnecessary materials and equipment. In October 2014, the DOJ declined to intervene and the case was partially unsealed. Discovery is ongoing in this case and is expected to continue into 2019. At this time, we believe the likelihood that we would incur a loss is remote and, as of September 30, 2018, no amounts have been accrued.

DOJ False Claims Act complaint - Iraq Subcontractor. In January 2014, the DOJ filed a complaint in the U.S. District Court for the Central District of Illinois against KBR and two former KBR subcontractors, including FKTC, alleging that three former KBR employees were offered and accepted kickbacks from these subcontractors in exchange for favorable treatment in the award and performance of subcontracts to be awarded during the course of KBR's performance of the LogCAP III contract in Iraq. The complaint alleges that as a result of the kickbacks, KBR submitted invoices with inflated or unjustified subcontract prices, resulting in alleged violations of the FCA and the Anti-Kickback Act. The DOJ's investigation dates back to 2004. We self-reported most of the violations and tendered credits to the U.S. government as appropriate. On May 22, 2014, FKTC filed a motion to dismiss, which the U.S. government opposed. Following the submission of our answer in April 2014, the U.S. government was granted a Motion to Strike certain affirmative defenses in March 2015. We do not believe this limits KBR's ability to fully defend all allegations in this matter. As of September 30, 2018, we have accrued our best estimate of probable loss related to an unfavorable settlement of this matter in "Other liabilities" on our condensed consolidated balance sheets. At this time, we believe the likelihood that we would incur a loss related to this matter in excess of the amounts we have accrued is remote. Discovery in the case has been extended to late 2018 and no trial date has been set.

Other matters

KBR Contract Claim on FKTC containers. KBR previously filed a claim before the ASBCA to recover the costs paid to FKTC to settle its requests for equitable adjustment. The DCMA had disallowed the majority of those costs. Those contract claims were stayed in 2013 at the request of the DOJ so that they could pursue the FCA case referenced above. Those claims were

40

reinstated in 2016. We tried our contract appeal in September 2017. Final briefing was filed in early 2018, and closing arguments were held on March 22, 2018. We expect to receive a ruling in late 2018.

Note 16. Other Commitments and Contingencies

Litigation and regulatory matters related to the Company’s restatement of its 2013 annual financial statements

Butorin v. Blount et al, is a May 2014 shareholder derivative complaint pending in the U.S. District Court of Delaware and filed on behalf of the Company naming certain current and former members of the Company's board of directors as defendants and the Company as a nominal defendant. The complaint alleges that the named directors breached their fiduciary duties by permitting the Company's internal controls to be inadequate. This case was dismissed on August 31, 2018.

We also received requests for information and a subpoena for documents from the SEC in 2014 regarding the restatement of our 2013 annual financial statements. We reached a settlement with the SEC in July 2018, which did not have a material impact on our financial statements.

Other matters

Unaoil Investigation. The DOJ, SEC, and the SFO are conducting investigations of Unaoil, a Monaco based company, in relation to international projects involving several global companies, including KBR, whose interactions with Unaoil are a subject of those investigations. KBR believes it is cooperating with the DOJ, SEC, and the SFO in their investigations, including through the voluntary submission of information and responding to formal document requests.

In re KBR, Inc. Securities Litigation. On October 20, 2017, lead plaintiffs filed an amended consolidated complaint asserting violations of the federal securities laws in connection with KBR's disclosures associated with the SFO's investigations of KBR and its affiliates relating to Unaoil. The Company and individual defendants filed a motion to dismiss the lawsuit on December 4, 2017. Briefing on the motion to dismiss was completed on February 19, 2018. Defendants' motion to dismiss was granted on August 31, 2018, and this matter is now concluded.

Tisnado vs DuPont, et al. In May 2016, KBR was served with a Fourth Amended Petition in Intervention and was brought into a lawsuit which was originally filed on November 14, 2014, in the 11th Judicial District Court of Harris County, Texas. This suit was brought by the family members of persons who died in an incident at the DuPont plant in LaPorte, Texas. We reached a settlement with the plaintiffs in 2018. This settlement was covered by insurance and did not have a material impact to our financial statements. This matter is now resolved.

PEMEX and PEP arbitration

On April 6, 2017, we entered into a settlement agreement with PEMEX and PEP related to a dispute from 2004. The settlement provided for a cash payment to Commisa of $435 million, payment by PEP of all VAT related to the settlement amount and mutual dismissals and releases of all claims related to the EPC 1 project. This matter is resolved and all amounts were paid by PEP in April 2017. As a result of the final settlement, we recognized additional revenues and gross profit of $35 million for the nine months ended September 30, 2017.

Note 18. Share Repurchases

Authorized Share Repurchase Program

On February 25, 2014, our Board of Directors authorized a plan to repurchase up to $350 million of our outstanding common shares, which replaced and terminated the August 26, 2011 share repurchase program. The authorization does not obligate the

43

Company to acquire any particular number of common shares and may be commenced, suspended or discontinued without prior notice. The share repurchases are intended to be funded through the Company’s current and future cash and the authorization does not have an expiration date.

Withheld to Cover Program

In addition to the plans above, we also have in place a "withheld to cover" program, which allows us to withhold common shares from employees in connection with the settlement of income tax and related benefit withholding obligations arising from the issuance of share based equity awards under the KBR, Inc. 2006 Stock and Incentive Plan.

The table below presents information on our share repurchases activity under these programs:

	Three Months Ended					Nine Months Ended

Note 19. Income per Share

Basic income per share is based upon the weighted average number of common shares outstanding during the period. Dilutive income per share includes additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued using the treasury stock method.

A reconciliation of the number of shares used for the basic and diluted income per share calculations is as follows:

	Three Months Ended September 30,		Nine Months Ended September 30,
Shares in millions	2018	2017	2018	2017
Basic weighted average common shares outstanding	141	140	140	141
Stock options and restricted shares	—	—	1	—
Diluted weighted average common shares outstanding	141	140	141	141

For purposes of applying the two-class method in computing income per share, there were $0.4 million and $1.5 million net earnings allocated to participating securities, or a negligible amount per share and $0.01 per share, for the three and nine months ended September 30, 2018, respectively. Net earnings allocated to participating securities for the three and nine months ended September 30, 2017 were $0.3 million and $1.1 million, respectively, or a negligible amount per share. The diluted income per share calculation did not include 1.4 million and 1.6 million antidilutive weighted average shares for the three and nine months ended September 30, 2018, respectively. The diluted income per share calculation did not include 1.9 million and 2.2 million antidilutive weighted average shares for the three and nine months ended September 30, 2017, respectively.

Note 20. Financial Instruments and Risk Management

Foreign currency risk. We conduct business globally in numerous currencies and are therefore exposed to foreign currency fluctuations. We may use derivative instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. We do not use derivative instruments for speculative trading purposes. We generally utilize foreign exchange forwards and currency option contracts to hedge exposures associated with forecasted future cash flows and to hedge exposures present on our balance sheet.

As of September 30, 2018, the gross notional value of our foreign currency exchange forwards and option contracts used to hedge balance sheet exposures was $54 million, all of which had durations of 9 days or less. We also had approximately $110 million (gross notional value) of cash flow hedges which had durations of approximately 22 months or less. The cash flow hedges are primarily related to the British Pound and Australian Dollar. The Australian Dollar hedges are primarily utilized to reduce the volatility of cash flows associated with the forecasted funding of JKC in Australian Dollars.

The fair value of our balance sheet and cash flow hedges included in "Other current assets" and "Other current liabilities" on our condensed consolidated balance sheets was immaterial at September 30, 2018 and December 31, 2017. The fair values of these derivatives are considered Level 2 under ASC 820, Fair Value Measurement, as they are based on quoted prices directly observable in active markets.

The following table summarizes the recognized changes in fair value of our balance sheet hedges offset by remeasurement of balance sheet positions. These amounts are recognized in our condensed consolidated statements of operations for the periods presented. The net of our changes in fair value of hedges and the remeasurement of our assets and liabilities is included in "Other non-operating income (expense)" on our condensed consolidated statements of operations.

	Three Months Ended						Nine Months Ended

Net	$	(2	)	$	(5	)	$	(7	)	$	(12	)

Subsequent Event

The Company uses interest rate swaps to reduce interest rate risk and to manage net interest expense.  On October 10, 2018 we entered into interest rate swap agreements with a notional value of $500 million to manage the interest rate exposure on our floating rate loans.  By entering into swap agreements, the Company converted the LIBOR rate based liability into a fixed rate liability for a four year period.  Under the swap agreements, the Company receives one month LIBOR rate and pays monthly a fixed rate of 3.055% for the term of the swaps.

Note 21. Recent Accounting Pronouncements

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedge Activities. This ASU is intended to improve and simplify accounting rules around hedge accounting. This ASU is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. Early adoption is permitted. We do not expect adoption of this ASU to be material to our ongoing financial reporting or on known trends, demand, uncertainties and events in our business.

45

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted, for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not expect adoption of this ASU to be material to our ongoing financial reporting or on known trends, demands, uncertainties and events in our business.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments. This ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable supportable forecast and is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted for annual periods after December 15, 2018, including interim periods within those annual periods. We are currently in the process of assessing the impact of this ASU on our financial statements. We have not yet determined the effect of the standard on our ongoing financial reporting or the future impact of adoption on known trends, demands, uncertainties and events in our business.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases with terms longer than 12 months. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. This ASU is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. Early adoption is permitted. We have developed a detailed plan to implement the new standard and, through a cross functional team, are assessing contractual arrangements that may qualify as leases under the new standard. The impact of the new standard will be a material increase to right of use assets and lease liabilities, primarily as a result of operating leases currently not recognized on our consolidated balance sheet.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Introduction

The purpose of MD&A is to disclose material changes in our financial condition since the most recent fiscal year-end and results of operations during the current fiscal period as compared to the corresponding period of the preceding fiscal year. The MD&A should be read in conjunction with the condensed consolidated financial statements, accompanying notes, and our 2017 Annual Report on Form 10-K.

Overview

Our business is organized into three core and two non-core business segments supporting the government services and hydrocarbons markets as follows:

Core business segments

• Government Services

• Technology

• Hydrocarbons Services

Non-core business segments

• Non-strategic Business

• Other

See additional information on our business segments in Notes 1 and 3 to our condensed consolidated financial statements.

Business Environment and Trends

46

Our business portfolio includes full life-cycle professional services, project solutions and technologies delivered across two primary verticals, government and hydrocarbons, aligned with the following:

• Early Project Advisory

• Project Definition

• Project Delivery

• Operations & Maintenance

Our core business capabilities and offerings include research and development, feasibility and solutions development, specialized technical consulting, systems integration, engineering and design services, highly specialized mission and logistics support solutions, process technologies and solutions, program management, construction, commissioning and startup services, and asset operations and maintenance services. We strive to deliver high quality solutions and services to support our clients' success today and to help them strengthen their strategic position for the future.

The global outlook for government services is favorable, with increased defense and space spending budgets driven in part by political instability, military conflicts, aging platforms and infrastructure, and the need for technology upgrades. We expect continued opportunities to provide enabling solutions and technologies to high impact, mission critical work. These opportunities continue to drive best value selections and customer confidence in the enterprise that we have built through our strategic acquisitions and organic growth. For example, with the completion of our acquisition of SGT in April 2018 and of Wyle and HTSI in 2016, we are well positioned as one of the top tier service providers to NASA, delivering enhanced life-cycle capabilities across multiple space centers to support our customer's needs in today's evolving civil, military and commercial space markets. Additionally, we increased our involvement in the Aspire Defence project in the U.K. through the acquisition in early 2018 of our former partner's 50% interest in the entities that provide construction and facilities management services to the MoD under a long-term PFI contract. Our PFI portfolio provides high visibility to consistent, stable income and cash flow over a long time horizon, with our largest PFI extending through 2041. As a result of organic growth and strategic acquisition, we expect a significant increase in total revenues, income and cash flow in our GS business segment in 2018 as compared to 2017.

We expect that a majority of the U.S. government business that we seek in the foreseeable future will be awarded through a competitive bidding process that may be impacted by delays, protests and other challenging dynamics. Additionally, our business may be affected by changes in the overall level of government spending and the alignment of our service and product offerings and capabilities with current and future budget priorities.

In the hydrocarbons sector, demand for our technologies, solutions and services is highly correlated to the level of capital and operating expenditure of our customers and prevailing market conditions. Significant volatility in commodity prices in recent years has resulted in many of our hydrocarbons customers taking steps to defer, suspend or terminate capital expenditures, resulting in delayed or reduced volumes of business across the sector. Recently, the combination of a growing global economy, technological development, and abundant sources of competitively priced feedstock are driving an increase in capital investment opportunities being evaluated and funded by our hydrocarbons customers. For example, we continue to see opportunities for midstream LNG expansion and greenfield projects to satisfy future LNG demand driven in large part by China's environmental policy promoting a transition from coal to gas. Additionally, downstream projects such as petrochemicals, chemicals and fertilizers benefit from low feedstock prices and increasing global development and consumer demand. From conceptual development studies to project delivery and asset management services, we seek to collaborate with our customers to meet the demands of the growing global economy.

Overall, we believe we have a balanced portfolio of global professional services, program delivery and technologies across the government services and hydrocarbons markets. We believe our increased mix of recurring government services and hydrocarbons services offers stability and predictability that enables us to be selective and disciplined as we pursue EPC projects across the hydrocarbons markets.

Three months ended September 30, 2018 compared to the three months ended September 30, 2017

Overview of Financial Results

For the quarter ended September 30, 2018, we generated revenues of $1.3 billion and net income attributable to KBR of $58 million. Highlights in the quarter include:

Our GS business segment, which provides full life-cycle support solutions to defense, space, aviation and missions for governmental agencies in the U.S., U.K. and Australia, generated revenues of $928 million and gross profit plus equity in earnings of $89 million for the quarter ended September 30, 2018. This compares to revenues of $582 million and gross profits plus equity in earnings of $53 million for the quarter ended September 30, 2017. The current quarter improvements were driven by revenue and earnings from strong organic growth within our logistics and engineering services business areas, the consolidation of the Aspire Defence subcontracting entities, and our acquisition of SGT.

Our Technology business segment, which provides licensed technologies and knowledge-based solutions and services to the hydrocarbons value chain, generated revenues of $81 million and gross profits of $23 million for the quarter ended September 30, 2018. This compares to revenues of $60 million and gross profits of $19 million for the quarter ended September 30, 2017. The current quarter improvements were driven by increased volume and progress earned, mix of work, and improved chargeability of our operating centers.

Our HS business segment, which provides comprehensive project and program delivery capability globally for the hydrocarbons value chain, generated revenues of $268 million and gross profit plus equity in earnings of $36 million in the quarter ended September 30, 2018. This compares to revenues of $388 million and gross profits plus equity in earnings of $35 million in the quarter ended September 30, 2017. The decrease in revenue and gross profit plus equity in earnings was primarily driven by projects that were completed or substantially completed during the past 12 months and a decrease in earnings on the Ichthys LNG project due to an EAC increase associated with an expected further delay in estimated completion date.

Our Non-strategic Business segment generated revenues of $1 million and a gross loss of $5 million during the quarter ended September 30, 2018 compared to revenues of $4 million and gross profit of $3 million in the quarter ended September 30, 2017. All Non-Strategic Business projects are substantially complete as of September 30, 2018. We continue to finalize project close-out activities and negotiate the settlement of claims and various other matters associated with these projects.

The information below is an analysis of our consolidated results for the three months ended September 30, 2018. See Results of Operations by Business Segment below for additional information describing the performance of each of our reportable segments.

Revenues	Three Months Ended September 30,
					2018 vs. 2017
Dollars in millions	2018		2017		$		%
Revenues	$	1,278	$	1,034	$	244	24	%

The increase in consolidated revenues was primarily driven by strong organic growth within our GS logistics and engineering services business areas, the consolidation of the Aspire Defence subcontracting entities as discussed in Note 5 to our condensed consolidated financial statements, our acquisition of SGT, and increased revenues in our Technology business segment. The increase was partially offset by decreased revenue in our HS segment caused by reduced activity and the completion or near completion of several projects in the U.S. and Canada, and decreased revenues in our non-strategic segment as we exit that business.

Gross Profit	Three Months Ended September 30,
					2018 vs. 2017
Dollars in millions	2018		2017		$		%
Gross profit	$	122	$	87	$	35	40	%

The increase in consolidated gross profit was primarily caused by strong organic growth in our GS logistics and engineering services business areas, the consolidation of the Aspire Defence subcontracting entities as discussed in Note 5 to our condensed consolidated financial statements, our acquisition of SGT, and increased profit in our Technology segment, partially offset by decreased profit in our HS segment associated with reduced activity on projects nearing completion.

Equity in Earnings of Unconsolidated Affiliates	Three Months Ended September 30,

Dollars in millions	2018		2017		$			%
Equity in earnings of unconsolidated affiliates	$	21	$	23	$	(2	)	(9	)%

The decrease in equity in earnings of unconsolidated affiliates was primarily due to the consolidation of the Aspire Defence subcontracting entities, reduced activity within our Affinity joint venture in our GS segment and a decrease in earnings on the Ichthys LNG project due to an EAC increase associated with an expected further delay in estimated completion date. These decreases were partially offset by increased earnings from our Brown & Root Industrial Services and EPIC joint ventures and increased earnings from joint ventures in Europe and Mexico.

General and Administrative Expenses	Three Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$		%
General and administrative expenses	$	(37	)	$	(37	)	$	—	—	%

General and administrative expenses remained consistent due to decreased G&A expense in our Other and HS business segments, offset by an increase in G&A expenses associated with the acquired SGT business and organic growth in our GS business segment. General and administrative expenses in the third quarter of 2018 and 2017 included $18 million and $23 million, respectively, related to corporate activities and $19 million and $14 million, respectively, related to the business segments.

Interest Expense	Three Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$			%
Interest expense	$	(20	)	$	(6	)	$	(14	)	233	%

The increase in interest expense was primarily due to increased borrowings and an increase in the weighted-average interest rate on our borrowings as a result of the refinancing transaction as discussed in Note 13 to our condensed consolidated financial statements.

Other Non-operating Loss	Three Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$		%
Other non-operating loss	$	(1	)	$	(4	)	$	3	(75	)%

Other non-operating loss includes interest income, foreign exchange gains and losses and other non-operating income or expense items. The change in other non-operating income was primarily due to reduced foreign exchange losses in the current quarter and an increase in interest income associated with the cash balances held by the Aspire Defence project entities. See Note 5 to our condensed consolidated financial statements for discussion of the Aspire entities.

Government Services

GS revenues increased by $346 million, or 59%, to $928 million in the third quarter of 2018, compared to $582 million in the third quarter of 2017. This increase was primarily due to an additional $136 million of revenues from the consolidation of the Aspire Defence subcontracting entities due to us becoming the primary beneficiary of these entities as a result of Carillion's liquidation, an additional $126 million of revenues from the acquisition of SGT and strong organic growth in our GS logistics and engineering services business areas. See Note 5 to our condensed consolidated financial statements for more information on the consolidation of the Aspire entities and the acquisition of SGT.

GS gross profit increased by $42 million, or 108%, to $81 million in the third quarter of 2018 compared to $39 million in the third quarter of 2017. This increase was primarily due to $14 million of gross profit from the consolidation of the Aspire Defence subcontracting entities due to us becoming the primary beneficiary of these entities as a result of Carillion's liquidation, $12 million of gross profit from the acquisition of SGT, increases from organic revenue growth in our logistics and engineering services business areas, and one-time favorable settlements on legacy CONCAP and LogCAP III matters which contributed $11 million to gross profit.

GS equity in earnings of unconsolidated affiliates decreased by $6 million, or 43%, to $8 million in the third quarter of 2018 compared to $14 million in the third quarter of 2017 primarily due to the consolidation of the Aspire Defence project entities due to us becoming the primary beneficiary of these entities as a result of Carillion's liquidation and reduced activity in our Affinity joint venture during the current quarter.

Technology

Technology revenues increased by $21 million, or 35%, to $81 million in the third quarter of 2018 compared to $60 million in the third quarter of 2017. This increase was primarily attributable to increased activity across the chemical, petrochemical and refining markets resulting in increased volume and progress earned and an increase in our proprietary equipment sales across the portfolio.

Technology gross profit increased by $4 million, or 21%, to $23 million in the third quarter of 2018 compared to $19 million in the third quarter of 2017. This increase was primarily driven by increased volume and mix of work as described above.

Hydrocarbons Services

HS revenues decreased by $120 million, or 31%, to $268 million in the third quarter of 2018, compared to $388 million in the third quarter of 2017. This decrease was primarily due to reduced activity on several projects nearing completion in the U.S and Canada. These decreases were partially offset by new wins and growth on existing projects during the third quarter of 2018.

HS gross profit decreased by $3 million, or 12%, to $23 million in the third quarter of 2018, compared to $26 million in the third quarter of 2017. The decrease was primarily due to reduced activity on projects nearing completion, partially offset by a one-time favorable settlement on an ammonia/urea plant in the U.S. which contributed $5 million to gross profit.

HS equity in earnings of unconsolidated affiliates increased by $4 million, or 44%, to $13 million in the third quarter of 2018, compared to earnings of $9 million in the third quarter of 2017. This increase was primarily due to a project specific joint venture in Europe reaching mechanical completion, improved performance on the Brown & Root Industrial Services and EPIC joint ventures, and increased revenues on a joint venture in Mexico. These increases were partially offset by a decrease in earnings on the Ichthys LNG project due to an EAC increase associated with an expected further delay in estimated completion date. See Note 10 to our condensed consolidated financial statements for more information on the Ichthys JV.

Non-strategic Business

Non-strategic Business revenues decreased by $3 million, or 75%, to $1 million in the third quarter of 2018 compared to $4 million in the third quarter of 2017. This decrease was primarily due to the substantial completion of several power projects as we exit that business.

Non-strategic Business gross loss was $5 million in the third quarter of 2018 compared to a gross profit of $3 million in the third quarter of 2017, a decrease of $8 million or 267%. This change was primarily due to the settlement of a legacy legal matter during the quarter.

Changes in Estimates

Information relating to our changes in estimates is discussed in Note 3 to our condensed consolidated financial statements.

Nine months ended September 30, 2018 compared to the nine months ended September 30, 2017

Overview of Financial Results

For the nine months ended September 30, 2018, we generated revenues of $3.6 billion and net income attributable to KBR of $238 million, compared to revenues of $3.2 billion and net income attributable to KBR of $159 million for the nine months ended September 30, 2017. The increase in revenues and net income were primarily driven by organic growth on existing projects in our GS business segment, the consolidation of the Aspire Defence subcontracting entities, our acquisition of SGT, organic growth in our technology segment, the recognition of variable consideration associated with the successful completion and performance testing of a major Hydrocarbons Services project, partially offset by the impact of the $35 million PEMEX settlement recognized in 2017 and the decrease in HS revenues related to projects that were completed or substantially completed during the last 12 months.

Our GS business segment generated revenues of $2.5 billion and gross profits plus equity in earnings of $226 million for the nine months ended September 30, 2018, compared to revenues of $1.6 billion and gross profits plus equity in earnings of $154 million for the nine months ended September 30, 2017. The improvements were driven by strong organic growth within our logistics and engineering services business areas, the consolidation of the Aspire Defence subcontracting entities as discussed in Note 5 to our condensed consolidated financial statements, which resulted in $382 million of additional revenues, and $216 million in revenues from the acquisition of SGT.

Our Technology business segment generated revenues of $215 million and gross profits of $61 million for the nine months ended September 30, 2018, compared to revenues of $196 million and gross profits of $50 million for the nine months ended September 30, 2017. The increase in revenue was primarily attributable to increased activity across the chemical, petrochemical and refining markets resulting in increased volume and progress earned and an increase in proprietary equipment sales across the portfolio. Profit margins were favorably impacted by mix of work and improved chargeability of our operating centers in the nine months ended September 30, 2018, resulting in higher gross profits compared to the nine months ended September 30, 2017.

Our HS business segment generated revenues of $894 million and gross profit plus equity in earnings of $107 million for the nine months ended September 30, 2018 compared to revenues of $1.4 billion and gross profits plus equity in earnings of $137 million for the nine months ended September 30, 2017. The decrease in revenue was primarily caused by projects that were completed or substantially completed during the last 12 months. The decrease in gross profit plus equity in earnings was primarily due to the reduction in revenues and the non-recurrence of the $35 million PEMEX settlement recognized in 2017. These decreases were partially offset by the recognition of variable consideration associated with the successful completion and performance testing of a major Hydrocarbons Services project and increased profit associated with commercial settlements on two projects in the close-out phase.

Our Non-strategic Business segment generated revenues of $1 million and a gross loss of $7 million for the nine months ended September 30, 2018 compared to revenues of $37 million and no gross profit for the nine months ended September 30, 2017. All Non-Strategic Business projects are substantially complete as of September 30, 2018. We continue to finalize project close-out activities and negotiate the settlement of claims and various other matters associated with these projects.

The information below is an analysis of our consolidated results for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. See Results of Operations by Business Segment below for additional information describing the performance of each of our reportable segments.

Revenues	Nine Months Ended September 30,
					2018 vs. 2017
Dollars in millions	2018		2017		$		%
Revenues	$	3,583	$	3,234	$	349	11	%

The increase in consolidated revenues was primarily driven by strong organic growth within our GS logistics and engineering services business areas, the consolidation of the Aspire Defence subcontracting entities as discussed in Note 5 to our condensed

53

consolidated financial statements, our acquisition of SGT, and increased revenues in our Technology segment. The increase was partially offset by decreased revenue in our HS segment caused by reduced activity and the completion or near completion of several projects in the U.S. and Canada, the non-recurrence of $35 million in revenue from the PEMEX settlement that occurred in 2017, and decreased revenues in our non-strategic segment as we exit that business.

Gross Profit	Nine Months Ended September 30,
					2018 vs. 2017
Dollars in millions	2018		2017		$		%
Gross profit	$	333	$	277	$	56	20	%

The increase in gross profit was primarily caused by strong organic growth in our GS logistics and engineering services business areas, the consolidation of the Aspire Defence subcontracting entities as discussed in Note 5 to our condensed consolidated financial statements, our acquisition of SGT, and increased profit in our Technology segment. These increases were partially offset by decreased profit in our HS segment due to reduced activity and the non-recurrence of the PEMEX settlement.

Equity in Earnings of Unconsolidated Affiliates	Nine Months Ended September 30,
					2018 vs. 2017
Dollars in millions	2018		2017		$			%
Equity in earnings of unconsolidated affiliates	$	54	$	64	$	(10	)	(16	)%

The decrease in equity in earnings of unconsolidated affiliates was primarily due to the consolidation of the Aspire Defence subcontracting entities, decreased earnings on our Affinity joint venture, reduced activity from a joint venture in Mexico, and a decrease in earnings on the Ichthys LNG project due to an EAC increase associated with an expected further delay in estimated completion date. These decreases were partially offset by an increase in earnings from our Brown & Root Industrial Services and EPIC joint ventures and a project specific joint venture in Europe. See Note 10 to our condensed consolidated financial statements for more information on the Ichthys LNG project.

General and Administrative Expenses	Nine Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$			%
General and administrative expenses	$	(113	)	$	(107	)	$	(6	)	6	%

The increase in general and administrative expenses was primarily due to $6 million of G&A expenses related to SGT which was acquired on April 25, 2018 and increased expense due to the organic growth in our GS business segment. These increases were partially offset by a decline in G&A expenses related to our Other business segment. General and administrative expenses in the nine months ended September 30, 2018 and 2017 included $60 million and $66 million, respectively, related to corporate activities and $53 million and $41 million, respectively, related to the business segments.

Acquisition and Integration Related Costs	Nine Months Ended September 30,
						2018 vs. 2017
Dollars in millions	2018			2017		$			%
Acquisition and integration related costs	$	(5	)	$	—	$	(5	)	N/A

The increase in acquisition and integration related costs was primarily due to $4 million of direct, incremental costs related to the acquisition of SGT and approximately $1 million related to the consolidation of the Aspire Defence subcontracting entities.

Gain on Consolidation of Aspire Entities	Nine Months Ended September 30,
					2018 vs. 2017
Dollars in millions	2018		2017		$		%
Gain on consolidation of Aspire entities	$	113	$	—	$	113	N/A

The gain on consolidation of Aspire entities was due to the $113 million gain recognized upon the consolidation of the Aspire Defence subcontracting entities. See Note 5 to our condensed consolidated financial statements for additional information.

Interest Expense	Nine Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$			%
Interest expense	$	(43	)	$	(16	)	$	(27	)	169	%

The increase in interest expense was primarily due to increased borrowings and an increase in the weighted-average interest rate on our borrowings as a result of the refinancing transaction as discussed in Note 13 to our condensed consolidated financial statements.

Other Non-operating Loss	Nine Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$		%
Other non-operating loss	$	(4	)	$	(9	)	$	5	(56	)%

Other non-operating income (expense) includes interest income, foreign exchange gains and losses and other non-operating income or expense items. The decrease in other non-operating expense was primarily due to a decrease in foreign exchange losses and an increase in interest income associated with the cash balances held by the Aspire Defence subcontracting entities. See Note 5 to our condensed consolidated financial statements for discussion of the Aspire Defence project.

Provision for Income Taxes	Nine Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$			%
Income before provision for income taxes and noncontrolling interests	$	335		$	214		$	121		57	%
Provision for income taxes	$	(74	)	$	(50	)	$	(24	)	48	%

Our provision for income taxes for the nine months ended September 30, 2018 reflects a 22% tax rate as compared to a 23% tax rate for the nine months ended September 30, 2017. The 2018 period provision for income taxes is higher than the 2017 period primarily due to higher income before provision for income taxes related to the gain of approximately $113 million recognized in the first quarter of 2018 as a result of obtaining control of the Aspire Defence project subcontracting joint ventures. See Note 14 to our condensed consolidated financial statements for further discussion on income taxes.

Net Income Attributable to Noncontrolling Interests	Nine Months Ended September 30,
							2018 vs. 2017
Dollars in millions	2018			2017			$			%
Net income attributable to noncontrolling interests	$	(23	)	$	(5	)	$	(18	)	360	%

The increase in net income attributable to noncontrolling interests was primarily caused by the recognition of variable consideration associated with the successful completion and performance testing of a major Hydrocarbons Services project.

Government Services

GS revenues increased by $833 million, or 51%, to $2.5 billion in the nine months ended September 30, 2018, compared to $1.6 billion in the nine months ended September 30, 2017. This increase was primarily due to an additional $382 million of revenues from the consolidation of the Aspire Defence project entities, an additional $216 million of revenues from the acquisition of SGT, and strong organic growth in our logistics and engineering services business areas. See Note 5 to our condensed consolidated financial statements for more information on the consolidation of the Aspire Defence subcontracting entities and the acquisition of SGT.

GS gross profit increased by $91 million, or 81%, to $204 million in the nine months ended September 30, 2018, compared to $113 million in the nine months ended September 30, 2017. This increase was primarily due to $42 million of gross profit from the consolidation of the Aspire Defence subcontracting entities, $19 million of gross profit from the acquisition of SGT, increases from organic revenue growth in our logistics and engineering services business areas, and one-time favorable settlements on legacy CONCAP and LogCAP III matters which contributed $11 million to gross profit.

GS equity in earnings of unconsolidated affiliates decreased by $19 million, or 46%, to $22 million in the nine months ended September 30, 2018 compared to $41 million in the nine months ended September 30, 2017. This decrease was primarily due to the consolidation of the Aspire Defence subcontracting entities.

Technology

Technology revenues increased by $19 million, or 10%, to $215 million in the nine months ended September 30, 2018, compared to $196 million in the nine months ended September 30, 2017 primarily due to an increase in our olefins and organic chemical technologies, partially offset by decreases in proprietary equipment sales, catalyst projects, and our Ecoplanning business.

Technology gross profit increased by $11 million, or 22%, to $61 million in the nine months ended September 30, 2018, compared to $50 million in the nine months ended September 30, 2017, primarily driven by mix of work and improved chargeability of our operating centers.

Hydrocarbons Services

HS revenues decreased by $467 million, or 34%, to $894 million in the nine months ended September 30, 2018, compared to $1.4 billion in the nine months ended September 30, 2017. This decrease was primarily due to reduced activity and the completion or near completion of several projects in the U.S. and Canada, and the non-recurrence of $35 million in revenue from the PEMEX settlement that occurred in 2017. These decreases were partially offset by new wins and growth on existing projects and the recognition of variable consideration associated with the successful completion and performance testing of a major Hydrocarbons Services project.

HS gross profit decreased by $39 million, or 34%, to $75 million in the nine months ended September 30, 2018, compared to $114 million in the nine months ended September 30, 2017. This decrease was primarily due to the non-recurrence of $35 million in revenue from the PEMEX settlement that occurred in 2017 and projects completing or nearing completion and the under recovery of resources. These decreases were partially offset by the recognition of variable consideration associated with the successful completion and performance testing of a major Hydrocarbons Services project and a one-time favorable settlement on an ammonia/urea plant in the U.S. which contributed $5 million to gross profit.

HS equity in earnings of unconsolidated affiliates increased by $9 million, or 39%, to $32 million in the nine months ended September 30, 2018, compared to $23 million in the nine months ended September 30, 2017. This increase was primarily due to an increase in earnings provided by a JV in Europe, increased earnings from the Brown & Root Industrial Services and EPIC joint ventures. These increases were partially offset by decreased earnings on a joint venture in Mexico and a decrease in earnings on the Ichthys LNG project due to an EAC increase and schedule delays. See Note 10 to our condensed consolidated financial statements for more information on the Ichthys LNG project.

57

Non-strategic Business

Non-strategic Business revenues decreased by $36 million, or 97%, to $1 million in the nine months ended September 30, 2018, compared to $37 million in the nine months ended September 30, 2017. This decrease was due to completion or near completion of two power projects as we exit that business.

Non-strategic Business incurred a gross loss of $7 million in the nine months ended September 30, 2018, compared to a loss of $0 million in the nine months ended September 30, 2017. This change was primarily due to the settlement of a legacy legal matter during the quarter.

Changes in Estimates

Information relating to our changes in estimates is discussed in Note 3 to our condensed consolidated financial statements. See Note 10 to our condensed consolidated financial statements for more information on the Ichthys JV.

Backlog of Unfilled Orders

Backlog generally represents the dollar amount of revenues we expect to realize in the future as a result of performing work on contracts and our pro-rata share of work to be performed by unconsolidated joint ventures. We generally include total expected revenues in backlog when a contract is awarded under a legally binding agreement. In many instances, arrangements included in backlog are complex, nonrepetitive and may fluctuate over the contract period dependent upon critical project decisions to be made by the customer. Additionally, nearly all contracts allow customers to terminate the agreement at any time for convenience. Where contract duration is indefinite and clients can terminate for convenience without compensating us for periods beyond the date of termination, backlog is limited to the estimated amount of expected revenues within the following twelve months. Certain contracts provide maximum dollar limits, with actual authorization to perform work under the contract agreed upon on a periodic basis with the customer. In these arrangements, only the amounts authorized are included in backlog. For projects where we act solely in a project management capacity, we only include the expected value of our services in backlog.

We define backlog, as it relates to U.S. government contracts, as our estimate of the remaining future revenue from existing signed contracts over the remaining base contract performance period (including customer approved option periods) for which work scope and price have been agreed with the customer. We define funded backlog as the portion of backlog for which funding currently is appropriated, less the amount of revenue we have previously recognized. Our GS backlog does not include any estimate of future potential delivery orders that might be awarded under our government-wide acquisition contracts, agency-specific indefinite delivery/indefinite quantity contracts, or other multiple-award contract vehicles nor does it include option periods that have not been exercised by the customer.

Within our GS business segment, we calculate estimated backlog for long-term contracts associated with the U.K. government's PFIs based on the aggregate amount that our client would contractually be obligated to pay us over the life of the project. We update our estimates of the future work to be executed under these contracts on a quarterly basis and adjust backlog if necessary.

We have included in the table below our proportionate share of unconsolidated joint ventures' estimated revenues. Since these projects are accounted for under the equity method, only our share of future earnings from these projects will be recorded in our results of operations. Our proportionate share of backlog for projects related to unconsolidated joint ventures totaled $2.7 billion at September 30, 2018 and $7.2 billion at December 31, 2017. Our backlog included in the table below for projects related to consolidated joint ventures includes 100% of the backlog associated with those joint ventures and totaled $6.2 billion at September 30, 2018 and $125 million at December 31, 2017.

58

The following table summarizes our backlog by business segment for the periods ended September 30, 2018 and December 31, 2017, respectively:

	September 30,		December 31,
Dollars in millions	2018		2017
Government Services	$	11,039	$	8,355
Technology	544		387
Hydrocarbons Services	1,895		1,822
Subtotal	13,478		10,564
Non-strategic Business	3		6
Total backlog	$	13,481	$	10,570

Backlog in our Government Services business segment at September 30, 2018 was $11.0 billion, an increase of $2.7 billion when compared to backlog of $8.4 billion at December 31, 2017. The increase was primarily due to including 100% of backlog associated with the consolidation of the Aspire Defence subcontracting entities as of September 30, 2018, as compared to our 50% proportionate share of backlog for these entities as of December 31, 2017, additional backlog resulting from the acquisition of SGT, and new awards, partially offset by workoff.

Backlog in our Technology business segment at September 30, 2018 was $544 million, an increase of $157 million when compared to backlog of $387 million at December 31, 2017. The increase was primarily the result of new awards, partially offset by workoff.

Backlog in our Hydrocarbons Services business segment at September 30, 2018 was $1.9 billion, an increase of $73 million when compared to backlog of $1.8 billion at December 31, 2017. The increase was primarily the result of new awards, partially offset by backlog workoff.

The difference between backlog of $13.5 billion and the remaining performance obligation as defined by ASC 606 of $10.1 billion is primarily due to our proportionate share of backlog related to unconsolidated joint ventures which is not included in our remaining performance obligation. See Note 4 to our condensed consolidated financial statements for discussion of the remaining performance obligation.

We estimate that as of September 30, 2018, 29% of our backlog will be executed within one year. Of this amount, 83% will be recognized in revenues on our condensed consolidated statement of operations and 17% will be recorded by our unconsolidated joint ventures. As of September 30, 2018, $76 million of our backlog relates to active contracts that are in a loss position.

As of September 30, 2018, 9% of our backlog was attributable to fixed-price contracts, 61% was attributable to PFIs and 30% of our backlog was attributable to cost-reimbursable contracts. For contracts that contain both fixed-price and cost-reimbursable components, we classify the individual components as either fixed-price or cost-reimbursable according to the composition of the contract; however, for smaller contracts, we characterize the entire contract based on the predominant component. As of September 30, 2018, $10.0 billion of our GS backlog was currently funded by our customers.

As of September 30, 2018, we had approximately $3.7 billion of priced option periods for U.S. government contracts that are not included in the backlog amounts presented above.

Transactions with Joint Ventures

We perform many of our projects through incorporated and unincorporated joint ventures. In addition to participating as a joint venture partner, we often provide engineering, procurement, construction, operations or maintenance services to the joint venture as a subcontractor. Where we provide services to a joint venture that we control and therefore consolidate for financial reporting purposes, we eliminate intercompany revenues and expenses on such transactions. In situations where we account for our interest in the joint venture under the equity method of accounting, we do not eliminate any portion of our revenues or expenses. We recognize the profit on our services provided to joint ventures that we consolidate and joint ventures that we record under the equity method of accounting primarily using the percentage-of-completion method. See Note 11 to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information. The information discussed therein is incorporated by reference into this Part I, Item 2.

Legal Proceedings

Information relating to various commitments and contingencies is described in Notes 15 and 16 to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q, and the information discussed therein is incorporated by reference into this Part I, Item 2.

Liquidity and Capital Resources

Hydrocarbons services projects generally require us to provide credit support for our performance obligations to our customers in the form of letters of credit, surety bonds or guarantees. Our ability to obtain new project awards in the future may be dependent on our ability to maintain or increase our letter of credit and surety bonding capacity, which may be further dependent on the timely release of existing letters of credit and surety bonds. As the need for credit support arises, letters of credit will be issued under our $500 million PLOC or our $500 million Revolver under our Senior Credit Facility. Letters of credit may also be arranged with our banks on a bilateral, syndicated or other basis. We believe we have adequate letter of credit capacity under our Senior Credit Facility and bilateral lines, as well as adequate surety bond capacity under our existing lines to support our operations, backlog, and foreseeable additional needs for the next 12 months.

Cash generated from operations and the new Senior Credit Facility are our primary sources of liquidity.  Our operating cash flow can vary significantly from year to year and is affected by the mix, terms, timing and percentage of completion of our hydrocarbons services projects.  We sometimes receive cash in the early phases of our larger hydrocarbons services fixed-price projects, technology projects, and those of our consolidated joint ventures in advance of incurring related costs.  On reimbursable contracts, we may utilize cash on hand or availability under our Senior Credit Facility to satisfy any periodic operating cash requirements for working capital, as we frequently incur costs and subsequently invoice our customers. We believe that existing cash balances, internally generated cash flows and availability under our Senior Credit Facility are sufficient to support our day-to-day domestic and foreign business operations for the next 12 months.

Cash and equivalents totaled $581 million at September 30, 2018 and $439 million at December 31, 2017 and consisted of the following:

	September 30,		December 31,
Dollars in millions	2018		2017
Domestic U.S. cash	$	108	$	184
International cash	170		194
Joint venture and Aspire Defence project cash	303		61
Total	$	581	$	439

Our cash balances are held in numerous accounts throughout the world to fund our global activities. Domestic cash relates to cash balances held by U.S. entities and is largely used to support project activities of those businesses as well as general corporate needs such as the payment of dividends to shareholders, repayment of debt and potential repurchases of our outstanding common stock.

Our international cash balances may be available for general corporate purposes but are subject to local restrictions, such as capital adequacy requirements and local obligations, including maintaining sufficient cash balances to support our underfunded U.K. pension plan and other obligations incurred in the normal course of business by those foreign entities. Repatriations of our undistributed foreign earnings are generally free of U.S. tax but may incur withholding and/or state taxes. We still must assess our future U.S. and non-U.S. cash needs such as 1) our anticipated foreign working capital requirements, including funding of our U.K. pension plan, 2) the expected growth opportunities across all geographical markets, 3) our plans to invest in strategic growth opportunities that may include acquisitions around the world and 4) funding and other financial obligations of existing projects. As of September 30, 2018, we have not changed our indefinite reinvestment decision on our undistributed earnings of our foreign subsidiaries.

Joint venture cash and Aspire Defence project cash balances reflect the amounts held by those entities that we consolidate for financial reporting purposes. These amounts are limited to those entities' activities and are not readily available for general corporate purposes; however, portions of such amounts may become available to us in the future should there be a distribution of dividends to the joint venture partners. We expect that the majority of the joint venture cash balances will be utilized for the corresponding joint venture projects.

As of September 30, 2018, substantially all of our excess cash was held in commercial bank time deposits or interest bearing short-term investment accounts with the primary objectives of preserving capital and maintaining liquidity.

Cash Flows

Cash flows activities summary
	Nine Months Ended September 30,
Dollars in millions	2018			2017
Cash flows provided by operating activities	$	36		$	238
Cash flows used in investing activities	(428		)	(4		)

Effect of exchange rate changes on cash	(18		)	13
Increase (decrease) in cash and equivalents	$	142		$	(25	)

Operating activities. Cash flows from operating activities result primarily from earnings and are affected by changes in operating assets and liabilities which consist primarily of working capital balances for projects. Working capital levels vary from year to year and are primarily affected by the Company's volume of work. These levels are also impacted by the mix, stage of completion and commercial terms of hydrocarbons services projects. Working capital requirements also vary by project depending on the type of client and location throughout the world. Most contracts require payments as the projects progress. Additionally, certain projects receive advance payments from clients. A normal trend for these projects is to have higher cash balances during the initial phases of execution which then decline to equal project earnings at the end of the construction phase. As a result, our cash position is reduced as customer advances are worked off, unless they are replaced by advances on other projects.

The primary components of our working capital accounts are accounts receivable, contract assets, accounts payable and contract liabilities. These components are impacted by the size and changes in the mix of our cost reimbursable versus fixed price projects, and as a result, fluctuations in these components are not uncommon in our business.

Cash provided by operations totaled $36 million in the first nine months in 2018 as compared to net income of $261 million. The difference primarily results from the non-cash gain on consolidation of Aspire Defence subcontracting entities of $113 million and net unfavorable changes of $139 million in working capital balances for projects as discussed below:

• The $144 million unfavorable cash flow impact related to accounts receivable was primarily related to increases in accounts receivable in our GS U.S. operations, increases in accounts receivable in the consolidated Aspire Defence subcontracting entities, since the date we obtained control, and increases in accounts receivable in our HS Americas operations. These increases are largely attributable to growth in our business and the transition associated with our recent acquisitions and system implementations. We generally expect these increases to reverse over time.

• The $4 million unfavorable cash flow impact related to contract assets was primarily related to increases in contract assets related to various projects in our HS Americas business, partially offset by decreases in contract assets in our Technology and GS businesses.

• The $72 million favorable cash flow impact related to accounts payable was primarily related to an increase in accounts payable related to the consolidated Aspire Defence subcontracting entities subsequent to the date we obtained control and growth in our business on various other U.S. government projects. This increase was partially offset by decreases in accounts payable related to our HS business segment.

• The $63 million unfavorable cash flow impact related to contract liabilities was primarily related to workoff on projects nearing completion within our HS business segment and various projects in our GS business segment.

• In addition, we received distributions of earnings from our unconsolidated affiliates of $16 million and contributed $30 million to our pension funds in the first nine months of 2018.

Cash provided by operations totaled $238 million in the first nine months in 2017 primarily resulting from net favorable changes of $160 million in working capital balances for projects as discussed below:

• Accounts receivable decreased primarily due to collections from customers within our HS business segment associated with several ammonia projects in the U.S. and a road construction project in the Middle East within our GS business segment.

• Contract assets decreased in the first nine months in 2017, due primarily to billings to a customer within our HS business segment associated with progress on a project in the U.S. These decreases were partially offset by the timing of billings to various customers within our Technology business segment.

• Claims receivable decreased in the first nine months of 2017 due to the billing and collection of the outstanding claims receivable associated with the PEMEX litigation settlement.

• Accounts payable decreased in the first nine months in 2017, primarily due to the power project within our Non-strategic Business segment as the project neared completion as well as several EPC projects that were nearing completion in the U.S. in our HS business segment.

• Contract liabilities decreased in the first nine months in 2017, primarily due to the work off of previous advances on two EPC ammonia projects in the U.S. within our HS business segment as well as a power project within our Non-strategic Business Segment that was substantially complete.

• We received distributions of earnings from our unconsolidated affiliates of $41 million and contributed approximately $28 million to our pension funds in the first nine months in 2017.

Investing activities. Cash used in investing activities totaled $428 million in the first nine months in 2018 and was primarily due to the acquisition of SGT and investment in JKC, partially offset by the incremental cash resulting from the consolidation of the Aspire Defence subcontracting entities.

Cash used in investing activities totaled $4 million in the first nine months in 2017 and was primarily used in the purchase of equipment.

Financing activities. Cash provided by financing activities totaled $552 million in the first nine months of 2018 and includes $120 million in borrowings on our terminated Credit Agreement, $130 million on our new Revolver, $1,052 million in borrowings on Term Loans A and B, offset by the $590 million payoff of our terminated Credit Agreement, $15 million in payments on our new Revolver, $47 million of debt issuance costs, $34 million for dividend payments to common shareholders and $56 million to acquire the noncontrolling interest in the Aspire project entities and the remaining 25% noncontrolling interest in one of our other joint ventures.

Cash used in financing activities totaled $272 million in the first nine months of 2017 and included $180 million of payments on our Credit Agreement, $52 million of common stock repurchases and $34 million for dividend payments to common shareholders.

Future sources of cash. We believe that future sources of cash include cash flows from operations, cash derived from working capital management, and cash borrowings under our Senior Credit Facility.

Future uses of cash. We believe that future uses of cash include working capital requirements, funding of recognized project losses, joint venture capital calls, capital expenditures, dividends, pension funding obligations, repayments of borrowings under our Senior Credit Facility, share repurchases and strategic investments including acquisitions. Our capital expenditures will be focused primarily on facilities and equipment to support our businesses. In addition, we will use cash to make payments under operating leases and various other obligations, including potential litigation payments, as they arise.

Other factors potentially affecting liquidity

Ichthys LNG Project. As discussed in Note 10 to our condensed consolidated financial statements, JKC has included in its project estimates-at-completion significant revenues associated with unapproved change orders and customer claims plus estimated recoveries of claims against suppliers and subcontractors. If JKC does not resolve these matters for the amounts recorded, we would be responsible for funding our pro-rata portion of costs ultimately necessary to complete the project.  Also, to the extent the client does not continue to provide adequate funding for the cost reimbursable activities for the project prior to resolution of these matters, the joint venture partners will be required to fund working capital requirements of JKC.

In addition, JKC has estimated it will incur substantial funding requirements to complete the power plant under the fixed price portion of the Ichthys LNG contract. While JKC believes these funding requirements are recoverable from the Consortium who abandoned the project as the original subcontractor, we expect it will take a legal process to complete such recovery. This legal process may take several years. As a result, we expect to fund JKC for our portion of the costs to complete the power plant as these legal proceedings are underway. JKC's obligations to the client are guaranteed on a joint and several basis by the joint

62

venture partners. To the extent our joint venture partners are unable to complete their obligations, we may be required to fund incremental amounts above our 30% ownership interest.

During the nine months ended September 30, 2018, we made additional investments in JKC of approximately $257 million to fund our proportionate share of the ongoing project execution activities. We are projecting our funding requirements to JKC to be approximately $250 million to complete the project, excluding future recoveries of claims and unapproved change orders.

Negotiations and legal proceedings with the client and the subcontractors are ongoing, the goal of which is to minimize these expected outflows.

U.K. pension obligation. We recognized on our balance sheet a funding deficit of $328 million (measured as the difference between the fair value of plan assets and the projected benefit obligation) for our frozen defined benefit pension plans. The total amounts of employer pension contributions paid for the nine months ended September 30, 2018 were $30 million and primarily related to our defined benefit plan in the U.K. The funding requirements for our U.K. pension plan are determined based on the U.K. Pensions Act 1995. Annual minimum funding requirements are based on a binding agreement with the trustees of the U.K. pension plan that is negotiated on a triennial basis; a valuation is currently ongoing and expected to be completed in 2019. The binding agreement also includes other assurances and commitments regarding the business and assets that support the U.K. pension plan. In the future, such pension funding may increase or decrease depending on changes in the levels of interest rates, pension plan performance and other factors. A significant increase in our funding requirements for the U.K. pension plan could result in a material adverse impact on our financial position.

Credit Agreement and Senior Credit Facility

Information relating to our Credit Agreement and Senior Credit Facility is described in Note 13 to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q, and the information discussed therein is incorporated by reference into this Part I, Item 2.

Nonrecourse Project Debt

Information relating to our nonrecourse project debt is described in Note 13 to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q, and the information discussed therein is incorporated by reference into this Part I, Item 2.

Off-Balance Sheet Arrangements

Letters of credit, surety bonds and guarantees. In connection with certain projects, we are required to provide letters of credit, surety bonds or guarantees to our customers. Letters of credit are provided to certain customers and counterparties in the ordinary course of business as credit support for contractual performance guarantees, advanced payments received from customers and future funding commitments. We have $1 billion in a committed line of credit under our Senior Credit Facility, comprised of the $500 million Revolver and $500 million PLOC. Additionally, we have approximately $320 million of uncommitted lines of credit to support the issuance of letters of credit. Surety bonds are also posted under the terms of certain contracts to guarantee our performance. As of September 30, 2018, with respect to our $500 million Revolver, we have $115 million of outstanding revolver borrowings and have issued $31 million of letters of credit, with $354 million of remaining capacity. With respect to our PLOC, we have $92 million of outstanding letters of credit and $408 million of remaining capacity. With respect to our $320 million of uncommitted lines of credit, we have utilized $220 million for letters of credit as of September 30, 2018, with $100 million of remaining capacity. The total remaining capacity of these committed and uncommitted lines of credit is approximately $862 million. Of the letters of credit outstanding under our Senior Credit Facility, none have expiry dates beyond the maturity date of the Senior Credit Facility. Of the total letters of credit outstanding, $172 million relate to our joint venture operations where the letters of credit are posted using our capacity to support our pro-rata share of obligations under various contracts executed by joint ventures of which we are a member.

Critical Accounting Policies and Estimates

We have updated our discussion of certain critical accounting policies and estimates since those presented in our 2017 Annual Report on Form 10-K, Part II, Item 7, for the fiscal year ended December 31, 2017. Except for the critical accounting policies and estimates updated, there have been no material changes to our discussion of critical accounting policies and estimates from those set forth in our 2017 Annual Report on Form 10-K, which is incorporated herein by reference, for the year ended December 31, 2017. Our updated discussion of critical accounting policies and estimates are included below.

See Note 1, Description of Company and Significant Accounting Policies, to our condensed consolidated financial statements for a discussion of the potential impact of new accounting standards on our unaudited condensed consolidated financial statements.

Deferred Taxes, Valuation Allowances, and Tax Contingencies. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. We record a valuation allowance to reduce certain deferred tax assets to amounts that are more-likely-than-not to be realized.  We evaluate the realizability of our deferred tax assets by assessing the valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to assess the likelihood of realization include our forecast of future taxable income exclusive of reversing temporary differences and carryforwards, future reversals of existing taxable temporary differences and available tax planning strategies that could be implemented to realize the net deferred tax assets.

We consider both positive and negative evidence when evaluating the need for a valuation allowance on our deferred tax assets in accordance with ASC 740.  Available evidence includes historical financial information supplemented by currently available information about future years.  Generally, historical financial information is more objectively verifiable than projections of future income and is therefore given more weight in our assessment.   We consider cumulative losses in the most recent twelve quarters to be significant negative evidence that is difficult to overcome in considering whether a valuation allowance is required. Conversely, we consider a cumulative income position over the most resent twelve quarters, to be significant positive evidence that a valuation allowance may not be required. 

Beginning in the fourth quarter of 2014, we were in a twelve quarter cumulative loss position and accordingly, had a valuation allowance against deferred tax assets of approximately $538 million.  In the fourth quarter of 2017, we achieved twelve quarters of cumulative U.S. taxable income which is inclusive of income generated in various countries within branches of our U.S. subsidiaries.  Income (loss) related to the U.S. branches totaled $163 million, ($72) million and $138 million for the fiscal years 2017, 2016, and 2015, respectively, and is included in the foreign component of income in the notes to the financial statements in our Form 10-K for the Fiscal Year Ended December 31, 2017.  We weighted this positive evidence heavily in our analysis to overcome the previously existing negative evidence of our twelve quarter cumulative loss position.  

We concluded that future taxable income and the reversal of deferred tax liabilities excluding those associated with indefinite-lived intangible assets were the only sources of taxable income available in determining the amount of valuation allowance to be recorded against our deferred tax assets.  The deferred tax liabilities we relied on are projected to reverse in the same jurisdiction and are of the same character as the temporary differences that gave rise to the deferred tax assets. The deferred tax liabilities are projected to reverse in the same periods as the deferred tax assets and are projected to reverse beginning in fiscal year 2018 through fiscal year 2026.  We estimated future taxable income by jurisdiction exclusive of reversing temporary differences and carryforwards and applied our foreign tax credit carryforwards based on the sourcing and character of those estimates and considered any limitations. 

As a result of these analyses and considerations, we reversed approximately $223 million of our valuation allowance on federal deferred tax assets as of December 31, 2017, $152 million of which related to foreign tax credit carryforwards, and $71 million of which related to other net deferred tax assets.  We did not release all of the valuation allowance as of December 31, 2017 because certain foreign tax credit carry forwards are projected to expire unused. During the nine months ended September 30, 2018, we further refined our provisional estimates related to the Deemed Repatriation Transition Tax and our estimates of future taxable income. As a result of these refinements, we further reduced our valuation allowance for deferred tax assets by $72 million primarily related to foreign tax credit carryforwards.

Our ability to utilize the unreserved foreign tax credit carryforwards is based on our ability to generate income from foreign sources of approximately $725 million prior to their expiration whereas our ability to utilize other net deferred tax assets exclusive of those associated with indefinite-lived intangible assets is based on our ability to generate U.S. forecasted taxable income of approximately $340 million.  While our current projections of taxable income exceed these amounts, changes in our forecasted ability to achieve taxable income in the applicable taxing jurisdictions could affect the ultimate realization of deferred tax assets.

64

Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. We recognize potential interest and penalties related to unrecognized tax benefits in income tax expense.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We invest excess cash and equivalents in short-term securities, primarily time deposits, which carry a fixed rate of return for a given duration of time. Additionally, a substantial portion of our cash balances are maintained in foreign countries.

We are exposed to market risk associated with changes in foreign currency exchange rates, which may adversely affect our results of operations and financial condition.

We are exposed to and use derivative instruments, such as foreign exchange forward contracts and options to hedge foreign currency risk related to non-functional currency assets and liabilities on our balance sheet. Each period, these balance sheet hedges are marked to market through earnings and the change in their fair value is offset by remeasurement of the underlying assets and liabilities. See Note 20 to our condensed consolidated financial statements and the information discussed therein is incorporated by reference into this Item 3.

We are exposed to market risk for changes in interest rates for borrowings under our Senior Credit Facility, of which there were $1.1 billion as of September 30, 2018.   Borrowings under our Credit Agreement bear interest at variable rates. Our weighted average interest rate for the nine months ended September 30, 2018 was 5.01%.  Our weighted average interest rate was 5.58% for the period subsequent to our refinancing transaction discussed in Note 13 to our condensed consolidated financial statements. As of September 30, 2018, we had no derivative financial instruments to manage interest rate risk related to outstanding borrowings. If interest rates were to increase by 50 basis points, pre-tax interest expense would increase by approximately $6 million in the next 12 months, based on outstanding borrowings as of September 30, 2018.

Item 4. Controls and Procedures

In accordance with Exchange Act Rules 13a-15 and 15d-15, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2018 to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms. Our disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Beginning January 1, 2018, we adopted ASC 606, Revenue from Contracts with Customers and we implemented changes to our processes and controls related to revenue recognition.  These included the development of new policies based on the five-step model provided in the new revenue standard, new training, ongoing contract review requirements, and gathering of information provided for disclosures.   

We consolidated certain Aspire Defence project entities as of January 15, 2018 and we completed the acquisition of SGT on April 25, 2018. We are in the process of integrating these businesses which may result in additions or changes to our internal controls over financial reporting.

Accounting Policies [Abstract]

Description of Company and Significant Accounting Policies

Description of Company and Significant Accounting Policies

KBR, Inc., a Delaware corporation, was formed on March 21, 2006 and is headquartered in Houston, Texas. KBR, Inc. and its wholly owned and majority-owned subsidiaries (collectively referred to herein as "KBR", the "Company", "we", "us" or "our") is a global provider of differentiated, professional services and technologies across the asset and program life-cycle within the government services and hydrocarbons industries. Our capabilities include research and development, feasibility and solutions development, specialized technical consulting, systems integration, engineering and design service, process technologies, program management, construction services, commissioning and startup services, highly specialized mission and logistics support solutions, and asset operations and maintenance services and other support services to a diverse customer base, including government and military organizations of the U.S., U.K. and Australia and a wide range of customers across the hydrocarbons value chain.

Principles of Consolidation

Our condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR and our wholly owned and majority-owned subsidiaries and VIEs of which we are the primary beneficiary. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. See Note 11 to our condensed consolidated financial statements for further discussion on our equity investments and VIEs. The cost method is used when we do not have the ability to exert significant influence. All material intercompany balances and transactions are eliminated in consolidation.

Amounts classified as "Costs and estimated earnings in excess of billings on uncompleted contracts" and "Billings in excess of costs and estimated earnings on uncompleted contracts" on the consolidated balance sheets of our Annual Report on Form 10-K for the year ended December 31, 2017 have been reclassified as "Contract assets" and "Contract liabilities" on the condensed consolidated balance sheets.

We have evaluated all events and transactions occurring after the balance sheet date but before the financial statements were issued and have included the appropriate disclosures.

Segment Reorganization

Effective January 1, 2018, we changed the name of our Engineering & Construction segment to the "Hydrocarbons Services" segment. This change reflects strategic shifts we have made in this business over recent years to evolve to more recurring and reimbursable engineering, consulting and industrial maintenance services, coupled with our de-emphasis in engaging in fixed price EPC projects except for those that fit within our commercial discipline.

Also effective January 1, 2018, we changed the structure of our internal organization in a manner that caused our consulting business to be moved from the Technology & Consulting business segment to the Hydrocarbons Services (formerly E&C) business segment. As of January 1, 2018, our segments consist of the following five reportable segments:

• Government Services

• Technology

• Hydrocarbons Services

• Non-Strategic Business

• Other

See Note 3 to our condensed consolidated financial statements for further discussion on our segments. We have presented our segment results reflecting these changes for all periods presented. In conjunction with the change in segments, the Company evaluated its goodwill associated with the technology and consulting reporting units using Level 3 fair value inputs, and no impairment indicators were identified.

Use of Estimates

The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses

during the reporting period. Actual results could differ from those estimates. Areas requiring significant estimates and assumptions by our management include but are not limited to the following:

• project revenues, costs and profits on engineering and construction contracts, including recognition of estimated losses on uncompleted contracts

• project revenues, award fees, costs and profits on government services contracts

• provisions for uncollectible receivables

• provisions for client claims and recoveries of costs from subcontractors, vendors and others

• provisions for income taxes and related valuation allowances and tax uncertainties

• recoverability of goodwill

• recoverability of other intangibles and long-lived assets and related estimated lives

• recoverability of equity method and cost method investments

• valuation of pension obligations and pension assets

• accruals for estimated liabilities, including litigation accruals

• consolidation of VIEs

• valuation of share-based compensation

• valuation of assets and liabilities acquired in business combinations

We classify revenue contract liabilities as current or noncurrent based on the timing of when we expect to recognize revenue. The noncurrent portion of contract liabilities is included in "Other liabilities" in our condensed consolidated balance sheets. If the underlying estimates and assumptions upon which the financial statements are based change in the future, actual amounts may differ from those included in the accompanying condensed consolidated financial statements.

Adoption of New Accounting Standards

ASU 2014-09, Revenue from Contracts with Customers, codified as ASC Topic 606. On January 1, 2018, we adopted ASC Topic 606 and the related amendments ("ASC 606") using the modified retrospective method applied to those contracts that were not completed as of December 31, 2017. Results for operating periods beginning after January 1, 2018 are presented under ASC 606, while comparative information has not been restated and continues to be reported in accordance with the accounting standards in effect for those periods. See Note 2 for a description of our accounting policy resulting from adoption of ASC 606.

We recognized the cumulative effect of initially applying ASC 606 as an adjustment to retained earnings in the balance sheet as of January 1, 2018 as follows:

	Balance at		Adjustments Due to			Balance at

The impacts of adoption were primarily related to: (1) conforming our contracts recorded over time from previously acceptable methods to the cost-to-cost percentage of completion methodology, (2) combining certain deliverables that were previously considered separate deliverables into a single performance obligation, and (3) separating certain contracts that were previously considered one deliverable into multiple performance obligations.

The impacts of adoption on our opening balance sheet were primarily related to reclassification of amounts between "Accounts receivable, net of allowance for doubtful accounts" and "Contract assets" based on whether an unconditional ri

ght to consideration has been established or not, and the deferral of costs incurred and payments received to fulfill a contract, which were previously recorded in income in the period incurred or received but under the new standard will generally be capitalized and amortized over the period of contract performance.

In connection with the consolidation of certain previously unconsolidated VIEs associated with the Aspire Defence project in the first quarter of 2018, we elected to early adopt ASC 606 for each of the remaining unconsolidated Aspire Defence contracting entities effective January 1, 2018. As a result of the adoption by the Aspire Defence contracting entities, we identified multiple performance obligations associated with the project deliverables that were previously accounted for as a single deliverable under its contract with the MoD. In addition to the above impacts of adoption on revenue and gross margin, the cumulative effect of the adoption by Aspire Defence contracting entities resulted in sufficient additional income that had been previously recorded as "Deferred income from unconsolidated affiliates" on our condensed consolidated balance sheets in the amount of $101 million, which was reversed and included in the cumulative effect adjustment. Also, deferred construction income in the amount of $87 million previously recorded in "Equity in and advance to unconsolidated affiliates" was reversed and included in the cumulative effect adjustment as a result of the early adoption of ASC 606 by the Aspire Defence contracting entities. Except for the Aspire Defence contract entities, we have availed the SEC exemption under ASU 2017-13 to defer the application of ASC 606 to our remaining unconsolidated joint ventures until January 1, 2019.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Our significant accounting policies are detailed in "Note 1. Description of Company and Significant Accounting Policies" of our Annual Report on Form 10-K for the year ended December 31, 2017. The following section represents revisions to those accounting policies due to the adoption of ASC 606 and the separate presentation of acquisition and integration related costs.

Revenue Recognition

Revenue is measured based on the amount of consideration specified in a contract with a customer. Revenue is recognized when and as our performance obligations under the terms of the contract are satisfied, which generally occurs with the transfer of control of the goods or services to the customer.

To determine the proper revenue recognition method for contracts, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more

than one performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate a combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, which is mainly because we provide a significant service of integrating a complex set of tasks and components into a single project or capability. Contracts that cover multiple phases of the product lifecycle (development, construction and maintenance & support) are typically considered to have multiple performance obligations even when they are part of a single contract.

For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. In cases where we do not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We provide product warranties to customers that are included in the sale and are not priced or sold separately or do not provide customers with a service in addition to assurance of compliance with agreed-upon specifications. We do not consider these types of warranties to be separate performance obligations.

The following is a description of the principal activities from which we generate revenues by reportable segment:

Government Services

For most of government services, the customer contracts with us to provide support solutions to defense, space, aviation and other programs and missions through long-term service contracts. The performance obligations related to these long-term service contracts are primarily created through the issuance of task orders by the customer because a service contract generally does not meet the criteria to be considered a contract under ASC 606 since it does not obligate the customer to issue any task orders and could be canceled without substantive penalty under termination for convenience clauses. Accordingly, each task order releases us to perform specific portions of the overall scope in the service contract and is typically accounted for as a separate contract because the task order establishes the enforceable rights and obligations and payment terms. Task orders can include option periods that may be approved by the customer at a later date depending on the customer's future needs and budget availability.

Many of our government services contracts include variable consideration consisting of base fees (a profit percentage applied to our target cost) or award fees (additional consideration based on performance criteria, subject to final customer approval). Variable consideration can also arise from modifications to the scope of services resulting in unapproved change orders or customer claims. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted) that is reasonably available to us.

Many of our government services contracts are for labor at agreed hourly rates on a cost reimbursable basis to the customer. These contracts are accounted for as a series of distinct services because (a) the labor is provided as a continuous service, (b) each time increment of labor provided is distinct, (c) the nature of the services provided is substantially the same, and (d) the pattern of transfer is the same. In these types of contracts, the entire amount of consideration is recognized as labor is provided.

We also enter into base operations support contracts to provide the resources to operate bases, installations, camps, and stations of military departments. Our base operations support contracts are either fixed price contracts or cost reimbursable contracts. For fixed price contracts, we bill the customer a fixed monthly fee and recognize revenue over time on a straight-line basis where our level of effort remains substantially the same from month to month or where that is not the case, using a cost-to-cost input measure of progress as services are provided. For cost reimbursable contracts, we bill the customer all direct costs incurred each month plus an agreed provisional rate for overhead and fee, which are finalized at a later date. Revenue for cost reimbursable contracts is recognized as the direct costs are incurred and billed because the base operations represent a series of distinct services and the direct costs are consistent with our level of effort each month. For the purpose of revenue recognition of the variable elements of the contracts, we apply the variable consideration considerations described above.

Revenue on our other types of government services contracts is primarily recognized over time using the cost-to-cost input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress because it best depicts the transfer of assets to the customer, which occurs as we incur costs on the contracts. Contract costs include actual direct project costs incurred and an allocation of our indirect costs.

Under the typical payment terms of our government services contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones.

Hydrocarbons Services

For most of our hydrocarbons services projects, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability and are therefore accounted for as single performance obligations.

It is common for our hydrocarbons services contracts to contain incentive fees, performance bonuses, penalties (liquidated damages) or other provisions, including claims and change orders that may either increase or decrease the transaction price. Incentives and other performance bonuses generally are awarded upon achievement of certain performance metrics, program milestones or cost targets. Liquidated damage penalties in our contracts are generally capped at a percentage of the total contract value. Liquidated damages may be related to schedule delays, typically calculated based on a daily rate, or tied to performance guarantees.

Substantially all of our performance obligations related to hydrocarbons services contracts are satisfied over time as work progresses due to the continuous transfer of control to the customer. Typically, revenue is recognized over time using the cost-to-cost input measure to measure progress because it best depicts the transfer of goods and services to the customer, which occurs as we incur costs on our contracts. Contract costs include all direct material and labor costs and those indirect costs related to contract performance. Indirect costs, included in cost of revenues, include charges for such items as facilities, engineering, project management, quality control, bids and proposals and procurement.

Under the typical payment terms of our hydrocarbons services contracts, the customer makes advance payments as well as interim payments as work progresses. The advance payment generally is not considered a significant financing component as we normally expect to recognize the advance payments in revenue within a year of receipt as work progresses on the related performance obligation.

Technology

Our technology contracts consist primarily of licensing, basic engineering design (together, the "LBED"), proprietary equipment ("PEQ") or catalyst contracts. LBED contracts are combined into one performance obligation as they are entered into at the same time and the licensed technology requires engineering and design. We may further combine LBED and PEQ contracts into one performance obligation if the contracts were negotiated as a package with a single commercial objective, and the customer contracts with us to provide a significant service of integrating these distinct goods and services into a single project or capability.

It is common for our technology contracts to contain variable consideration including contingent milestone payments and penalties (liquidated damages) that may increase or decrease the transaction price. Contingent milestone payments are primarily related to decisions made by the customer after the LBED has been completed, such as a go or no-go decision on the project. Liquidated damage penalties in our technology contracts are typically triggered by late delivery and are calculated based on a weekly rate and are capped at a percentage of the total contract value.

Substantially all of our performance obligations related to technology contracts are satisfied over time as work progresses. Typically, revenue is recognized over time using the cost-to-cost input measure to measure progress because it best depicts the transfer of assets to the customer, which occurs as we incur costs on our contracts. Contract costs include all direct material and labor costs and those indirect costs related to contract performance and are recognized as the performance obligation is satisfied.

Under the typical payment terms of our technology contracts, the customer makes advance payments as well as interim payments as work progresses and certain progress milestones are met. The advance payment generally is not considered a significant financing component as we normally expect to recognize the advance payments in revenue within a year of receipt as work progresses on the related performance obligation.

Contract Estimates

Contract Modifications

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment.

As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly through a Company-wide disciplined project review process in which management reviews the progress and execution of our performance obligations and the estimate at completion (EAC). As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule and the related changes in estimates of revenues and costs. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer, among other variables.

We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the period it is identified.

Contracts are often modified to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

We account for contract modifications as a separate contract when the modification results in the promise to deliver additional goods or services that are distinct and the increase in price of the contract is for the same amount as the stand-alone selling price of the additional goods or services included in the modification.

We estimate variable consideration at the most likely amount to which we expect to be entitled. Any variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted) that is reasonably available to us.

We allocate variable consideration entirely to a performance obligation or to a distinct good or service within a performance obligation if it relates specifically to our efforts to satisfy the performance obligation or transfer the distinct good or service, and the allocation represents the amount of consideration to which we expect to be entitled.

Claims Against Vendors and Subcontractors

We include claims to vendors, subcontractors and others as a receivable and a reduction in recognized costs when enforceability of the claim is established by the contract and the amounts are reasonably estimable and probable of being recovered. Reductions in costs are recognized to the extent of the lesser of the amounts management expects to recover or to costs incurred.

Accounts receivable

Accounts receivable are recorded based on contracted prices when we obtain an unconditional right to payment under the terms of our contracts.

We establish an allowance for doubtful accounts based on the assessment of our clients' willingness and ability to pay. In addition to such allowances, there are often items in dispute or being negotiated that may require us to make an estimate as to the ultimate outcome. Past due receivable balances are written off when our internal collection efforts have been unsuccessful in collecting the amounts due.

Contract assets and liabilities

Billing practices are governed by the contract terms of each project based upon costs incurred, achievement of milestones or pre-agreed schedules. Billings do not necessarily correlate with revenue recognized using the cost-to-cost method of revenue recognition. Contract assets include unbilled amounts typically resulting from revenue under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to

payment is not unconditional. Contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue.

Retainage, included in contract assets, represents the amounts withheld from billings by our clients pursuant to provisions in the contracts and may not be paid to us until the completion of specific tasks or the completion of the project and, in some instances, for even longer periods. Retainage may also be subject to restrictive conditions such as performance guarantees.

Our contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. We classify contract liabilities as current or noncurrent based on the timing of when we expect to recognize revenue. The noncurrent portion of contract liabilities is included in "Other liabilities" in our condensed consolidated balance sheets.

Acquisition and integration related costs

Acquisition and integration related costs consist of third party transaction expenses representing legal, consulting and investment banking-related costs that are direct, incremental costs incurred prior to the closing of an acquisition and direct, incremental costs incurred to integrate the operations of newly acquired businesses into the Company's existing infrastructure as well as other initiatives to combine the newly merged companies into new infrastructure.

Segment Reporting [Abstract]

Business Segment Information

Business Segment Information

We are organized into three core business segments and two non-core business segments. Our three core business segments focus on our core strengths in technical services relating to government services, technology, and hydrocarbons services. Our two non-core business segments are our Non-strategic Business segment, which includes businesses we intend to exit upon completion of existing contracts because they are no longer a part of our future strategic focus, and "Other," which includes our corporate expenses and general and administrative expenses not allocated to the other business segments. Our business segments are described below:

Government Services. Our GS business segment provides full life-cycle support solutions to defense, space, aviation and other programs and missions for military and other government agencies in the U.S., U.K. and Australia. As program management integrator, KBR covers the full spectrum of defense, space, aviation and other government programs and missions from research and development; through systems engineering, test and evaluation, systems integration and program management; to operations support, maintenance and field logistics. Our recent acquisitions, as described in Note 5 to our condensed consolidated financial statements, have been combined with our existing U.S. operations within this business segment and operate under the single "KBRwyle" brand.

Technology. Our Technology business segment combines KBR's proprietary technologies, equipment and catalyst supply and associated knowledge-based services into a global business for refining, petrochemicals, inorganic and specialty chemicals as well as gasification, syngas, ammonia, nitric acid and fertilizers. From early planning through scope definition, advanced technologies and project lifecycle support, KBR's Technology segment works closely with customers to provide the optimal approach to maximize their return on investment.

Hydrocarbons Services. Our HS business segment provides comprehensive project and program delivery capability globally. Our key capabilities leverage our operational and technical excellence as a global provider of EPC for onshore oil and gas; LNG/GTL; oil refining; petrochemicals; chemicals; fertilizers; offshore oil and gas (shallow-water, deep-water and subsea); floating solutions (FPUs, FPSO, FLNG & FSRU); maintenance services (via the “Brown & Root Industrial Services” brand); and consulting services provided under our three specialist consulting brands, Granherne, Energo and GVA.

Non-strategic Business. Our Non-strategic Business segment represents the operations or activities that we intend to exit upon completion of existing contracts. All Non-Strategic Business projects are substantially complete. We continue to finalize project close-out activities and negotiate the settlement of claims and various other matters associated with these projects.

Other. Our Other business segment includes corporate expenses and general and administrative expenses not allocated to the business segments above.

The following table presents revenues, gross profit (loss), equity in earnings of unconsolidated affiliates, general and administrative expenses, acquisition and integration related costs, gain on disposition of assets, gain of consolidation of Aspire entities, and operating income (loss) by reporting segment. The prior year balances have been recast to reflect the change in segments as described in Note 1 to our condensed consolidated financial statements.

Changes in Project-related Estimates

There are many factors that may affect the accuracy of our cost estimates and ultimately our future profitability. These include, but are not limited to, the availability and costs of resources (such as labor, materials and equipment), productivity and weather, and for unit rate and construction service contracts, the availability and detail of customer supplied engineering drawings. With a portfolio of more than one thousand contracts, we sometimes realize both lower and higher than expected margins on projects in any given period. We recognize revisions of revenues and costs in the period in which the revisions are known. This may result in the recognition of costs before the recognition of related revenue recovery, if any.

Changes in project-related estimates by business segment that significantly impacted operating income were as follows:

Hydrocarbons Services

We recognized changes to equity in earnings as a result of various changes to estimates on the Ichthys LNG project during the three and nine months ended September 30, 2017. See Note 10 for a discussion of the matters impacting this project during the three and nine months ended September 30, 2018.

In the second quarter of 2018, we recognized a favorable change in estimated revenues and net income associated with variable consideration recognized as a result of successful completion and performance testing of a major Hydrocarbons Services project.

The PEMEX and PEP arbitration settlement (see Note 16 to our condensed consolidated financial statements) resulted in additional revenues and gross profit of $35 million during the nine months ended September 30, 2017.

We recognized revenue of $23 million and $54 million from performance obligations satisfied in previous periods for the three and nine month periods ended September 30, 2018, respectively.

On September 30, 2018, we had $10.1 billion of transaction price allocated to remaining performance obligations. We expect to recognize approximately 30% of our remaining performance obligations as revenue within one year, 24% in years two through five, and 46% thereafter. Revenue associated with our remaining performance obligations to be recognized beyond one year includes performance obligations related to Aspire Defence and Fasttrax projects, which have contract terms extending through 2041 and 2023, respectively. The balance of remaining performance obligations does not include variable consideration that was determined to be constrained as of September 30, 2018.

Acquisitions, Dispositions and Other Transactions

Stinger Ghaffarian Technologies Acquisition

On April 25, 2018, we acquired 100% of the outstanding stock of Stinger Ghaffarian Technologies ("SGT"). SGT is a leading provider of high-value engineering, mission operations, scientific and IT software solutions in the government services market. We accounted for this transaction using the acquisition method under ASC 805, Business Combinations. The acquisition is reported within our GS business segment. Aggregate base consideration for the acquisition was $355 million, plus $13 million of working capital and other purchase price adjustments set forth in the purchase agreement. We initially recognized goodwill of $257 million arising from the acquisition, which primarily relates to future growth opportunities based on an expanded service offering and other expected synergies from the combined operations. Approximately $237 million of the goodwill is deductible for tax purposes. The intangible assets recognized were comprised of customer relationships and backlog. These intangibles will be amortized over a weighted-average period of 19 years. During the third quarter of 2018, we recognized an adjustment to reflect the final working capital settlement, which increased other current assets and decreased the fair value of consideration transferred by $3 million.

We funded the acquisition with borrowings under our new Senior Credit Facility that were entered into concurrently with the acquisition. See Note 13 to our condensed consolidated financial statements for information related to our new Senior Secured Credit Facility. We recognized direct, incremental costs related to this acquisition of $1 million and $4 million during the three and nine months ended September 30, 2018, respectively, which are included in "Acquisition and integration related costs" on the condensed consolidated statements of operations.

The following table summarizes the consideration paid for this acquisition and the fair value of the assets acquired and liabilities assumed as of the acquisition date.

The acquired SGT business contributed $126 million and $216 million of revenues and $12 million and $19 million of gross profit for the three and nine month periods ended September 30, 2018, respectively, within our GS business segment.

Aspire Defence Subcontracting Joint Ventures

On January 15, 2018, Carillion plc ("Carillion"), our U.K. partner in the joint ventures that provide the construction and related support services to Aspire Defence Limited, entered into compulsory liquidation. Carillion no longer performs any of the services for the project, as we have stepped in to deliver both construction and support services without disruption. In accordance with the commercial arrangements of the project company and its lenders, Carillion was excluded from future business and benefit from its interest in the project and we have assumed operational management and control of the subcontracting joint ventures.

During the first quarter of 2018, we evaluated our rights and obligations under the joint venture agreements and other commercial arrangements of the project company and its lenders. We concluded Carillion's liquidation was a reconsideration event for KBR to reevaluate the primary beneficiary of the subcontracting joint ventures in which we were partners. We concluded KBR is the primary beneficiary as it has the power to direct activities having the most significant impact on the economic performance of the subcontracting joint ventures. Consequently, KBR began consolidating these entities in its financial statements effective January 15, 2018.

Prior to obtaining control of these entities, we accounted for our 50% investment in each of the subcontracting joint ventures under the equity method of accounting. The balance of our net equity investments in these entities was approximately $5 million as of January 15, 2018. As a result of obtaining control of the subcontracting joint ventures, we accounted for these transactions under the acquisition method of accounting for business combinations in accordance with ASC 805. Consequently, we remeasured our equity interests in each of the subcontracting joint ventures to fair value, which resulted in a gain of approximately $113 million included in "Gain on consolidation of Aspire entities" in our condensed consolidated statements of operations. The fair value of each of the subcontracting joint ventures was determined using a discounted cash flow model with future cash flows based on internal forecasts of revenue and expenses over the remaining life of the subcontract agreements. To arrive at our future cash flows, we used estimates of economic and market assumptions, including growth rates in revenues, costs, estimates of future expected changes in operating margins, tax rates and cash expenditures. The estimated cash flows were discounted using a weighted-average cost of capital that reflected current market conditions and the risk profile for each of the subcontracting joint ventures.

We recognized goodwill of approximately $44 million, which was primarily related to the deferred tax liabilities associated with the contract-related intangible assets acquired in the transaction. None of the goodwill is deductible for tax purposes. The contract-related intangible assets have estimated useful lives ranging 4 to 23 years. During the third quarter of 2018, we made immaterial adjustments and reclassifications to the previously reported assets acquired and liabilities assumed upon obtaining control of the subcontracting joint ventures including an increase to accounts receivable of $10 million and decrease to intangible assets of approximately $9 million. Certain data necessary to complete the purchase price allocation is not yet available and primarily relates to the final tax returns that provide the underlying tax basis of the assets and liabilities. The following table summarizes the fair value of the assets acquired and liabilities assumed as of the date we obtained control of the subcontracting joint ventures.

On April 18, 2018, we completed the acquisition of Carillion's interests in the subcontracting entities for $50 million pursuant to a share and business purchase agreement and approval by Aspire Defence Limited, the Aspire Defence Limited project lenders and the MoD. We accounted for the change in KBR's interest as an equity transaction. The difference between the noncontrolling interests of $124 million in the subcontracting entities at the date of acquisition and the cash consideration paid to Carillion was recognized as a net increase to "PIC" of $74 million for the nine month period ended September 30, 2018. We incurred $0 million and $1 million of acquisition-related costs for the three and nine months ended September 30, 2018, which were recorded in "Acquisition and integration related costs" on our condensed consolidated statements of operations.

The results of operations of the subcontracting entities have been included in our condensed consolidated statements of operations for periods subsequent to assuming control on January 15, 2018. The acquired subcontracting joint ventures contributed $138 million and $387 million of revenues and $14 million and $42 million of gross profit for the three and nine month periods ended September 30, 2018, respectively, within our GS business segment.

The following supplemental pro forma condensed consolidated results of operations assume that SGT and the Aspire Defence subcontracting joint ventures had been acquired as of January 1, 2017. The supplemental pro forma information was prepared based on the historical financial information of SGT and the Aspire Defence subcontracting joint ventures and has been adjusted to give effect to pro forma adjustments that are both directly attributable to the transaction and factually supportable. Pro forma adjustments were primarily related to the amortization of intangibles, interest on borrowings related to the acquisitions, and the reclassification of the gain on consolidation of the Aspire entities to January 1, 2017. Accordingly, this supplemental pro forma financial information is presented for informational purposes only and is not necessarily indicative of what the actual results of operations of the combined company would have been had the acquisitions occurred on January 1, 2017, nor is it indication of future results of operations.

Sigma Bravo Pty Ltd Acquisition

During the fourth quarter of 2017, we acquired 100% of the outstanding common shares of Sigma Bravo Pty Ltd ("Sigma Bravo"). Sigma Bravo provides information management, technical support and training services as well as operational support to the Australian Defence Force.

The aggregate purchase price of the acquisition was $9 million. We recognized goodwill of $1 million arising from the acquisition, which relates primarily to customer relationships and future growth opportunities to expand services provided to the Australian Defence Force. None of the goodwill is deductible for income tax purposes. The final settlement of the working capital adjustment occurred in the second quarter of 2018 and did not have a material effect on our condensed consolidated financial statements. In the third quarter of 2018, we recorded a deferred tax liability and corresponding increase to goodwill of approximately $2 million associated with the acquired intangible assets.

Subsequent Event

On October 11, 2018 we sold our interest in our EPIC joint venture for approximately $24 million. As of September 30, 2018, our balance in "Equity in and advances to unconsolidated affiliates" associated with this joint venture was approximately $24 million.

Cash and Equivalents

We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and equivalents include cash balances held by our wholly owned subsidiaries as well as cash held by joint ventures that we consolidate. Joint venture and the Aspire project cash balances are limited to specific project activities and are not available for other projects, general cash needs or distribution to us without approval of the board of directors of the respective entities. We expect to use this cash for project costs and distributions of earnings. However, some of the earnings distributions may be paid to other KBR entities where the cash can be used for general corporate needs.

As a result of the adoption of ASC 606 on January 1, 2018, unbilled accounts receivable is classified in "Accounts receivable" in our condensed consolidated balance sheets as it represents the amounts that have been recorded in revenue based on contracted prices for which we have obtained an unconditional right to payment under the terms of our contracts. Retainage is now recorded in "Contract Assets" in our condensed consolidated balance sheets when the right to payment of the retainage is conditional under the terms of our contracts. Prior to the adoption of ASC 606, unbilled accounts receivables were classified as "Costs and estimated earnings in excess of billings on uncompleted contracts" and retainage was classified within "Accounts receivable".

Contract Assets and Contract Liabilities

Contract Assets and Contract Liabilities

The timing of revenue recognition, billings and cash collections results in accounts receivable, contract assets, and contract liabilities on the condensed consolidated balance sheets.

Our contract assets by business segment are as follows:

	September 30,		December 31,
Dollars in millions	2018		2017		$ Change			% Change
Government Services	$	118	$	274	$	(156	)	(57	)%

Non-strategic Business	—		—		—			N/A
Total	$	214	$	383	$	(169	)	(44	)%

The decrease in contract assets was primarily caused by the initial adjustment due to the adoption of ASC 606, offset by normal business operations and the acquisition of $21 million of contract assets from the purchase of SGT as described in Note 5 to our condensed consolidated financial statements.

Our contract liabilities by business segment are as follows:

	September 30,		December 31,
Dollars in millions	2018		2017		$ Change		% Change
Government Services	$	240	$	85	155		182	%

Non-strategic Business	5		8		(3	)	(38	)%
Total	$	464	$	368	96		26	%

The increase in contract liabilities was primarily related to the acquisition of $161 million of contract liabilities associated with the Aspire Defence project joint ventures, partially offset by normal business operations and the recognition of the incentive fee associated with an Australian LNG project.

Revenue recognized for the nine months ended September 30, 2018 that was included in the contract liability balance at December 31, 2017 was $247 million.

Receivables [Abstract]

Claims and Accounts Receivable

Claims and Accounts ReceivableOur claims and accounts receivable balance not expected to be collected within the next 12 months was $96 million and $101 million as of September 30, 2018 and December 31, 2017, respectively. Claims and accounts receivable primarily reflects claims filed with the U.S. government related to payments not yet received for costs incurred under various U.S. government cost reimbursable contracts within our GS business segment. These claims relate to disputed costs or contracts where our costs have exceeded the U.S. government's funded value on the task order. Included in the amount is $73 million as of September 30, 2018 and $79 million as of December 31, 2017, respectively, related to Form 1s issued by the U.S. government questioning or objecting to costs billed to them. See Note 15 of our condensed consolidated financial statements for additional information. The amount also includes $23 million and $22 million as of September 30, 2018 and December 31, 2017, respectively, related to contracts where our reimbursable costs have exceeded the U.S. government's funded values on the underlying task orders or task orders where the U.S. government has not authorized us to bill. We believe the remaining disputed costs will be resolved in our favor, at which time the U.S. government will be required to obligate funds from appropriations for the year in which resolution occurs.

Unapproved Change Orders, Claims and Estimated Recoveries of Claims Against Suppliers and Subcontractors

Unapproved Change Orders, Claims, and Estimated Recoveries of Claims Against Suppliers and Subcontractors

The amounts of unapproved change orders, claims and estimated recoveries of claims against suppliers and subcontractors included in determining the profit or loss on contracts are as follows:

Dollars in millions	2018			2017
Amounts included in project estimates-at-completion at January 1,	$	924		$	294
Increase (decrease), including foreign currency effect	39			483
Approved change orders	(4		)	(4		)
Amounts included in project estimates-at-completion at September 30,	$	959		$	773
Amounts recognized over time based on progress at September 30,	$	922		$	687

As of September 30, 2018, the predominant component of the change orders, customer claims and estimated recoveries of claims against suppliers and subcontractors above relates to our proportionate share of unapproved change orders and claims associated with the Ichthys LNG Project discussed below.

KBR intends to vigorously pursue approval and collection of amounts still due under all unapproved change orders and claims, as well as resolution of contingencies within reserved amounts with subcontractors and clients. Further, there are additional claims that KBR believes it is entitled to recover from its clients and from subcontractors which have been excluded from estimated revenues and profits at completion as appropriate under U.S. GAAP. These commercial matters may not be resolved in the near term. Our current estimates for the above unapproved change orders, customer claims and estimated recoveries of claims against suppliers and subcontractors may prove inaccurate and could result in significant changes to the estimated revenues, costs and profits at completion on the underlying projects.

Ichthys LNG Project

Project Status

We have a 30% ownership interest in the JKC joint venture ("JKC"), which has contracted to perform the engineering, procurement, supply, construction and commissioning of onshore LNG facilities for a client in Darwin, Australia (the "Ichthys LNG Project"). The contract between JKC and its client is a hybrid contract containing both cost-reimbursable and fixed-price (including unit-rate) scopes.

The Ichthys LNG Project is substantially complete on a cost-to-cost basis. All of the components of the plant, except for the combined cycle power plant ("Power Plant"), have been completed and handed over to the client. The Power Plant includes five gas turbine generators which are complete and handed over to the client, and three steam turbine generators (the "STGs") which are currently forecasted to be completed by the end of the second quarter 2019. At the current level of progress, which includes portions of the power plant already completed, the plant is capable of LNG production.

Unapproved Change Orders and Claims

JKC has entered into commercial contracts with multiple suppliers and subcontractors to execute various scopes of work on the project. Certain of these suppliers and subcontractors have made contract claims against JKC for recovery of costs and extensions of time in order to progress the works under the scope of their respective contracts due to a variety of issues related to changes to the scope of work, delays and lower than planned subcontractor productivity. In addition, JKC has incurred costs related to scope increases and other factors, and has made claims to its client for matters for which JKC believes reimbursement is entitled under the contract.

JKC believes any amounts paid or payable to the suppliers and subcontractors in settlement of their contract claims related to cost-reimbursable scope are an adjustment to the contract price, and accordingly JKC has made claims for contract price adjustments under the reimbursable portion of the contract between JKC and its client. However, the client disputed some of these contract price adjustments and subsequently withheld certain payments. In order to facilitate the continuation of work under the contract while we worked to resolve this dispute, the client agreed to a contractual mechanism (“Funding Deed”) in 2016 providing funding in the form of an interim contract price adjustment to JKC and consented to settlement of subcontractor claims as of that date related to the cost-reimbursable scope. While the client reserved its rights under this funding mechanism, settlement funds (or interim contract price adjustment) have been paid by the client. JKC in turn settled these subcontractor claims which have been funded through the Funding Deed by the client.

If JKC's claims against its client which were funded under the Funding Deed remain unresolved by December 31, 2020, JKC will be required to refund sums funded by the client under the terms of the Funding Deed. We, along with our joint venture partners, are jointly and severally liable to the client for any amounts required to be refunded. While JKC continued to pursue settlement of these disputes with the client, JKC initiated arbitration proceedings in 2017 and is planning other arbitrations against the client to resolve open claims.

Our proportionate share of the total amount of the contract price adjustments under the Funding Deed included in the unapproved change orders and claims related to our unconsolidated affiliates discussed above is $163 million and $177 million as of September 30, 2018 and December 31, 2017, respectively. The difference in these values is strictly due to exchange rate fluctuations.

In September and October 2017, additional settlements pertaining to suppliers and subcontractors under the cost reimbursable portion of the contract were presented to the client. The client consented to these settlements and paid for them but reserved its rights. In reliance, JKC in turn settled these claims with the associated suppliers and subcontractors. The formal contract price adjustments for these settlements remained pending at September 30, 2018, but unlike amounts funded under the Funding Deed, there is no requirement to refund these amounts to the client by a date certain.

In October 2018, JKC received a favorable ruling from an arbitration tribunal. The ruling determined a contract interpretation in JKC's favour, to the effect that delay and disruption costs payable to subcontractors under the cost-reimbursable scope of the EPC contract are for the client's account. JKC contends this ruling resolves the reimbursability of the subcontractor settlement sums under the Funding Deed and additional settlements made in September and October 2017.  Pursuant to this decision, JKC is undertaking steps for a formal contract adjustment to the reimbursable portion of the contract for these settlement claims of which $332 million are included in the recognized unapproved change orders as of September 30, 2018.

There has been deterioration of paint on certain exterior areas of the plant. The client has requested, and has funded, paint remediation for a portion of the facilities. The client has requested a remediation plan for the remainder of the facilities, but JKC and its client have not resolved who is responsible for the paint defects and the manner in which it is to be remediated. JKC’s profit estimate at completion includes those revenues and costs for remediation activities that it has been directed to perform and are being funded by the client. JKC has also started proceedings against the paint manufacturer and made demands on insurance related to these issues.

As discussed above, the additional costs associated with these various claims and related issues have been included in determining estimated profit at completion. Estimated recoveries associated with the additional change orders, customer claims, and claims against suppliers and subcontractors have also been included in determining estimated profit at completion. Our current estimates for the above unapproved change orders and customer claims may prove inaccurate and could result in significant changes to the estimated revenue, costs and profits at completion on the underlying projects.

Other Matters

JKC is entitled to an amount of profit and overhead (“TRC Fee”) which is a fixed percentage of the target reimbursable costs ("TRC") under the reimbursable component of the contract which was to be agreed by JKC and its client. At the time of the contract, JKC and its client agreed to postpone the fixing of the TRC until after a specific milestone in the project had been achieved. Although the milestone was achieved, JKC and its client have been unable to reach agreement on the TRC. This matter was taken to arbitration in 2017. A decision was issued in December 2017 which provided some further basis for determination of the TRC amount and the TRC Fee. JKC has included an estimate for the TRC Fee in its determination of profit at completion at December 31, 2017 based on the contract provisions and the decision from the December 2017 arbitration and terms of the EPC contract with the client. JKC has submitted the revised estimate of the TRC Fee to the client. The parties have not agreed the revised estimate.

If the above matters are not resolved with the client for the amounts recorded, or to the extent JKC is unsuccessful in retaining amounts paid to it under the Funding Deed and other funding mechanisms used by the client, we would be responsible for our pro-rata portion of any additional costs and refunded sums in excess of the final adjusted contract price, which could have a material adverse effect on our results of operations, financial position and cash flows. Additionally, to the extent the client does not provide adequate and proper funding for project activities prior to resolution of these matters, the joint venture partners will be required to fund working capital requirements of JKC in the near term which could have a material adverse effect on our financial position and cash flows.

Combined Cycle Power Plant

Pursuant to JKC's fixed-price scope of its contract with its client, JKC awarded a fixed-price EPC contract to a subcontractor for the design, construction and commissioning of a combined cycle power plant. The subcontractor was a consortium consisting of General Electric and GE Electrical International Inc. and a joint venture between UGL Infrastructure Pty Limited and CH2M Hill (collectively, the "Consortium"). On January 25, 2017, JKC received a Notice of Termination from the Consortium, and the Consortium ceased work on the Power Plant and abandoned the construction site. JKC believes the Consortium materially breached its subcontract and repudiated its obligation to complete the Power Plant, plus undertook actions making it more difficult and more costly for the works to be completed by others after the Consortium abandoned the site. Subsequently, the Consortium filed a request for arbitration with the ICC asserting that JKC repudiated the contract. The Consortium also sought an order that the Consortium validly terminated the subcontract. JKC has responded to this request, denying JKC committed any breach of its subcontract with the Consortium and restated its claim that the Consortium breached and repudiated its subcontract with JKC and is furthermore liable to JKC for all costs to complete the Power Plant.

JKC prevailed in a legal action against the Consortium requiring the return of materials, drawings and tools following their unauthorized removal from the site. JKC discovered incomplete and defective engineering designs, defective workmanship on the site, missing, underreported and defective materials; and the improper termination of key vendors/suppliers. JKC's investigations also indicate that progress of the work claimed by the Consortium was over-reported. JKC has evaluated the cost to complete the Consortium's work, which significantly exceeds the awarded fixed-price subcontract value. JKC's cost to complete the Power Plant includes re-design efforts, additional materials and significant re-work. These costs represent estimated recoveries of claims against the Consortium and have been included in JKC's estimate to complete the Consortium's remaining obligations.

JKC is pursuing recourse against the Consortium to recover all of the costs to complete the Power Plant, plus the additional interest, and/or general damages by all means inclusive of calling bank guarantees provided by the Consortium partners. In April 2018, JKC prevailed in its legal action to call the bank guarantees (bonds) and subsequently called the bonds of two of the Consortium members, receiving funds totaling $52 million. Each of the Consortium partners has joint and several liability with respect to all obligations under the subcontract. JKC intends to pursue recovery of all additional amounts due from the Consortium via various legal remedies available to JKC.

Estimated costs to complete the Power Plant that have been determined to be probable of recovery from the Consortium under U.S. GAAP have been included as a reduction of cost in our estimate of profit at completion. The estimated recoveries exclude interest, liquidated damages and other related costs which JKC intends to pursue recovery from the Consortium.

As of September 30, 2018, JKC estimated claims against the Consortium were approximately $1.9 billion for recovery of these expected costs. The arbitration is likely to be set for hearing in the first half of 2020. JKC has also recently initiated suits against the parent companies of the Consortium members based on their payment and performance guarantees.

To the extent JKC is unsuccessful in prevailing in the Arbitration or the Consortium members are unable to satisfy their financial obligations in the event of a decision favorable to JKC, we would be responsible for our pro-rata portion of unrecovered costs from the Consortium. This could have a material adverse impact on the profit at completion of the overall contract and thus on our consolidated statements of operations, financial position and cash flow. Additionally, to the extent JKC does not resolve this matter with the Consortium in the near term, the joint venture partners have been and will continue to be required to fund JKC's completion of the combined cycle power plant which could have a material adverse effect on our financial position and cash flows. Further, if our partners in JKC do not fulfill their obligations under the subcontract, we could be exposed to the full amount of those funding requirements and potential losses as a result of the nature of the JKC JV agreement.

Ichthys Project Funding

JKC has recorded significant unapproved change orders and claims with the client as well as estimated recoveries of claims against suppliers and subcontractors arising from issues related to changes to the work scope, delays and lower than planned subcontractor activity discussed above. As a result of the ongoing disputes with the client and pursuit of recoveries against the Consortium through arbitration, additional contributions from the JKC joint venture partners are required to fund the project. During the nine months ended September 30, 2018, we made investment contribution to JKC of approximately $257 million to fund our proportionate share of the ongoing project execution activities. Our estimate of additional investment contributions increased by $100 million to approximately $250 million to complete the project, excluding future recoveries of claims and unapproved change orders.

Liquidated damages

Some of our hydrocarbons services contracts have schedule dates and performance obligations that, if not met, could subject us to penalties for liquidated damages. These generally relate to specified activities that must be completed by a set contractual date or by achievement of a specified level of output or throughput. Each contract defines the conditions under which a customer may make a claim for liquidated damages. However, in some instances, liquidated damages are not asserted by the customer, but the potential to do so is used in negotiating or settling claims and closing out the contract. Any accrued liquidated damages are recognized as a reduction in revenues in our condensed consolidated statements of operations.

In addition to the accrued liquidated damages, it is possible that liquidated damages that have not been included in our estimates at completion in determining project income related to several projects totaling $9 million and $9 million at September 30, 2018 and December 31, 2017, respectively, could be incurred if the projects are completed as currently forecasted. However, based upon our evaluation of our performance and other mitigating factors, we have concluded these liquidated damages are not probable.

Equity Method Investments and Variable Interest Entities

Equity Method Investments and Variable Interest Entities

We conduct some of our operations through joint ventures, which operate through partnership, corporation, undivided interest and other business forms and are principally accounted for using the equity method of accounting. Additionally, the majority of our joint ventures are VIEs.

The following table presents a rollforward of our equity in and advances to unconsolidated affiliates:

	September 30,			December 31,
Dollars in millions	2018			2017
Beginning balance	$	387		$	369

Ending balance	$	724		$	387

(a) As further discussed in Note 1 to our condensed consolidated financial statements, deferred construction income in the amount of $87 million previously recorded in "Equity in and advance to unconsolidated affiliates" was reversed and included in the cumulative effect adjustment as a result of the early adoption of ASC 606 by the Aspire Defence project joint ventures.

(b) From 2014 through 2017, we received cash dividends in excess of the carrying value of one of our unconsolidated joint ventures. We have no obligation to return any portion of the cash dividends received. We recorded excess dividends as "Deferred income from unconsolidated affiliates" on our condensed consolidated balance sheets and recognized these dividends as earnings are generated by the investment. As further discussed in Note 1 to our condensed consolidated financial statements, the adoption of ASC Topic 606 by this unconsolidated joint venture resulted in the reversal of the "Deferred income from unconsolidated affiliates" balance of $101 million in our condensed consolidated balance sheets as of December 31, 2017 in the cumulative effect adjustment of the change in accounting policy.

(c) In 2018, investments included a $257 million investment to fund JKC.

Unconsolidated Variable Interest Entities

For the VIEs in which we participate, our maximum exposure to loss consists of our equity investment in the VIE and any amounts owed to us for services we may have provided to the VIE, reduced by any unearned revenues on the project. Our maximum exposure to loss may also include our obligation to fund our proportionate share of any future losses incurred. As of September 30, 2018, we do not project any losses related to these joint venture projects. Where our performance and financial obligations are joint and several to the client with our joint venture partners, we may be further exposed to losses above our ownership interest in the joint venture.

The following summarizes the total assets and total liabilities as reflected in our condensed consolidated balance sheets related to our unconsolidated VIEs in which we have a significant variable interest but are not the primary beneficiary. Amount disclosed as Aspire Defence entities for 2017 reflect both contracting and subcontracting entities related to the Aspire Defence project.

Related Party Transactions

We often provide engineering, construction management and other subcontractor services to our joint ventures and our revenues include amounts related to these services. For the nine months ended September 30, 2018 and 2017, our revenues included $145 million and $85 million, respectively, related to the services we provided to our joint ventures, primarily the Ichthys JV within our HS business segment. Under the terms of an alliance agreement with our EPIC joint venture, EPIC provides certain pipe fabrication services to KBR. EPIC provided no services to KBR under the agreement in the nine months ended September 30, 2018 and $3 million of services to KBR under the agreement in the nine months ended September 30, 2017.

Under the terms of our TSA with Brown & Root Industrial Services joint venture, we collect cash from customers and make payments to vendors and employees on behalf of the joint venture. For the nine months ended September 30, 2018 and 2017, we incurred approximately $2 million and $4 million, respectively, of reimbursable costs under the TSA.

Amounts included in our condensed consolidated balance sheets related to services we provided to our unconsolidated joint ventures as of September 30, 2018 and December 31, 2017 are as follows:

	September 30,		December 31,

Senior Credit Facility

On April 25, 2018, the Company refinanced its $1 billion Credit Agreement due September 2020 (our "Credit Agreement"). The new senior secured credit facility ("Senior Credit Facility") consists of a $500 million revolving credit facility ("Revolver"), a $500 million performance letter of credit facility ("PLOC"), a $350 million Delayed Draw Term Loan A, ("Term Loan A") and an $800 million Term Loan B ("Term Loan B"). The Revolver, PLOC and Term Loan A mature in April 2023 and the Term Loan B matures in April 2025. The Term Loan A may be drawn upon until the earlier of becoming fully drawn or June 30, 2019 (the "Availability Period"). Borrowings under the Term Loan A may only be used to fund investments in JKC. See Note 10 to our condensed consolidated financial statements for a discussion on JKC.

The interest rate with respect to the Term Loan B is LIBOR plus 3.75%. The interest rates with respect to the Revolver and Term Loan A are based on, at the Company's option, adjusted LIBOR plus an additional margin or base rate plus additional margin. The Senior Credit Facility provides for fees on letters of credit issued under the PLOC at varying rates, as shown below. Additionally, there is a commitment fee with respect to the Revolver, PLOC and Term Loan A. The details of the applicable margins and commitment fees are based on the Company's consolidated leverage ratio as follows:

	Revolver and Term Loan A
Consolidated Leverage Ratio	LIBOR Margin		Base Rate Margin		Performance Letter of Credit Fee		Commitment Fee
Greater than or equal to 4.00 to 1.00	3.25	%	2.25	%	1.95	%	0.450	%
Less than 4.00 to 1.00 but greater than or equal to 3.00 to 1.00	3.00	%	2.00	%	1.80	%	0.400	%
Less than 3.00 to 1.00 but greater than or equal to 2.00 to 1.00	2.75	%	1.75	%	1.65	%	0.375	%
Less than 2.00 to 1.00	2.50	%	1.50	%	1.50	%	0.350	%

The Term Loan A provides for quarterly principal payments of 2.50% of the aggregate principal amount commencing with the fiscal quarter ending June 30, 2019. The Term Loan B provides for quarterly principal payments of 0.25% of the initial aggregate principal amounts commencing with the fiscal quarter ending September 30, 2018.

The Senior Credit Facility contains customary restrictive covenants, subject to certain permitted amounts and exceptions, including covenants limiting our ability to incur additional liens and indebtedness, enter into asset sales, repurchase our equity shares and make certain types of investments.

The Revolver, PLOC, and Term Loan A contain financial maintenance covenants of a maximum consolidated leverage ratio and a consolidated interest coverage ratio (as such terms are defined in the Senior Credit Facility). Our consolidated leverage ratio as of the last day of any fiscal quarter, commencing with the fiscal quarter ending June 30, 2018, may not exceed 4.50 to 1 and reducing gradually during 2019 and 2020 to 3.50 to 1. Our consolidated interest coverage ratio as of the last day of any fiscal quarter, commencing with the fiscal quarter ending June 30, 2018 and thereafter, may not be less than 3.00 to 1. As of September 30, 2018, we were in compliance with our financial covenants.

Nonrecourse Project Debt

Fasttrax Limited, a joint venture in which we indirectly own a 50% equity interest with an unrelated partner, was awarded a concession contract in 2001 with the U.K. MoD to provide a Heavy Equipment Transporter Service to the British Army. Under the terms of the arrangement, Fasttrax Limited operates and maintains 91 HETs for a term of 22 years. The purchase of the HETs by the joint venture was financed through two series of bonds secured by the assets of Fasttrax Limited and a bridge loan totaling approximately £84.9 million (approximately $120 million at the exchange rate on the date of the transaction). The secured bonds are an obligation of Fasttrax Limited and are not a debt obligation of KBR as they are nonrecourse to the joint venture partners. Accordingly, in the event of a default on the notes, the lenders may only look to the assets of Fasttrax Limited for repayment. The bridge loan of approximately £12.2 million (approximately $17 million at the exchange rate on the date of the transaction) was replaced when we and the other joint venture partners funded the joint venture with equity and subordinated notes in 2005.

The secured bonds were issued in two classes consisting of Class A 3.5% Index Linked Bonds in the amount of £56 million (approximately $79 million at the exchange rate on the date of the transaction) and Class B 5.9% Fixed Rate Bonds in the amount of £16.7 million (approximately $24 million at the exchange rate on the date of the transaction).  Semi-annual payments on both classes of bonds commenced in March 2005 and will continue through maturity in 2021.  The subordinated notes payable to each of the partners initially bear interest at 11.25% increasing to 16% over the term of the notes until maturity in 2025.  Semi-annual payments on the subordinated notes commenced in March 2006. For financial reporting purposes, the portion of the subordinated notes payable to us is eliminated in consolidation and consequently, only our partner's portion of the subordinated notes appears in the condensed consolidated financial statements.

Income Taxes

Income Taxes

Our estimated annual effective tax rate for 2018 is 23% including the discrete tax impact of obtaining control of the Aspire Defence subcontracting joint ventures that was recorded at a lower rate than our estimated annual tax rate for 2018. The effective tax rate was approximately 28% and 22% for the three and nine months ended September 30, 2018, respectively. The effective

tax rate was approximately 24% and 23% for the three and nine months ended September 30, 2017, respectively. Income taxes for the three months ended September 30, 2018 were adversely impacted by newly issued interpretations from the IRS related to the Tax Cuts and Jobs Act and their cumulative impact to January 1, 2018.

On December 22, 2017, the U.S. enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act") making broad and complex changes to the U.S. tax code. SEC Staff Accounting Bulletin (SAB) 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In January, April, and August of 2018, the Internal Revenue Service ("IRS") issued guidance and proposed regulations which provides additional clarification on certain aspects of the Deemed Repatriation Transition Tax ("Transition Tax") calculation. We applied this guidance which impacted certain tax elections, increasing our estimated Transition Tax liability to approximately $227 million which was fully offset by foreign tax credits generated by the deemed repatriation as well as foreign tax credit carryforwards available for use. We anticipate additional IRS guidance relative to Transition Tax and other aspects of the Tax Act to be forthcoming throughout the remainder of 2018. As of September 30, 2018, we have not yet completed our tax accounting for the income tax effects of the Tax Act and will continue to revise our provisional amounts as additional guidance becomes available. The Company expects to complete our accounting within the prescribed measurement period.

Our estimated annual effective rate is subject to change based on the actual jurisdictions where our 2018 earnings are generated and further guidance issued by the IRS.

The valuation allowance for deferred tax assets as of September 30, 2018 and December 31, 2017 was $145 million and $217 million, respectively. The change in the valuation allowance was a decrease of $4 million and decrease of $11 million for the three months ended September 30, 2018 and 2017, respectively, and a decrease of $72 million and decrease of $30 million for the nine months ended September 30, 2018 and 2017, respectively. The decrease in valuation allowance primarily related to changes in foreign tax credit carryforwards due to the refinement of provisional impacts recorded related to the Transition Tax. The valuation allowance is primarily related to foreign tax credit carryforwards and foreign and state net operating loss carryforwards that, in the judgment of management, are not more likely than not to be realized. The ultimate realization of deferred tax assets is dependent on the generation of future taxable income, in the appropriate character and source, during the periods in which those temporary differences become deductible or within the remaining carryforward period. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income and tax-planning strategies in making this assessment.

The provision for uncertain tax positions included in "Other liabilities" and "Deferred income taxes" on our condensed consolidated balance sheets as of September 30, 2018 and December 31, 2017 was $97 million and $184 million, respectively. The reduction in the provision for uncertain tax positions of approximately $8 million for the three months ended September 30, 2018 reflects the release of provisions associated with the effective settlement of an audit with tax authorities as well as the expiration of statute of limitations, partially offset by a provision due to a change in measurement of a tax position as a result of an ongoing appeals process. Additionally, the change in the provision for uncertain tax positions for the nine months ended September 30, 2018 contains a settlement with a tax authority, resulting in a write off of the deferred tax asset that previously had an uncertain tax position liability recorded against it, and consequently had no impact on tax expense.

United States Government Contract Work [Abstract]

U.S. Government Matters

U.S. Government Matters

We provide services to various U.S. governmental agencies, which include the U.S. DoD, NASA, and the Department of State. We may have disagreements or experience performance issues on our U.S. government contracts. When performance issues arise under any of these contracts, the U.S. government retains the right to pursue various remedies, including challenges to expenditures, suspension of payments, fines and suspensions or debarment from future business with the U.S. government. The negotiation, administration and settlement of our contracts are subject to audit by the DCAA. The DCAA serves in an advisory role to the DCMA, and the DCMA is responsible for the administration of the majority of our contracts. The scope of these audits include, among other things, the validity of direct and indirect incurred costs, provisional approval of annual billing rates, approval of annual overhead rates, compliance with the FAR and CAS, compliance with certain unique contract clauses and audits of certain aspects of our internal control systems. Based on the information received to date, we do not believe the completed or ongoing government audits will have a material adverse impact on our results of operations, financial position or cash flows.

Legacy U.S. Government Matters

Between 2002 and 2011, we provided significant support to the U.S. Army and other U.S. government agencies in support of the war in Iraq under the LogCAP III contract. We have been in the process of closeout of the LogCAP III contract since 2011, and we expect the closeout process to continue through at least 2019. As a result of our work under LogCAP III, there are claims

and disputes pending between us and the U.S. government which need to be resolved in order to close the contract. The closeout process includes resolving objections raised by the U.S. government through a billing dispute process referred to as Form 1s and MFRs. We continue to work with the U.S. government to resolve these issues and are engaged in efforts to reach mutually acceptable resolution of these outstanding matters. However, for certain of these matters, we have filed claims with the ASBCA or the COFC. We also have matters related to ongoing litigation or investigations involving U.S. government contracts. We anticipate billing additional labor, vendor resolution and litigation costs as we resolve the open matters. At this time, we cannot determine the timing or net amounts to be collected or paid to close out these contracts.

Form 1s

The U.S. government has issued Form 1s questioning or objecting to costs we billed to them under cost reimbursable contracts primarily related to our use of private security and our provision of containerized housing under the LogCAP III contract discussed below. As a consequence of the issuance of the Form 1s, the U.S. government has withheld payment to us on outstanding invoices, pending resolution of these matters.

The U.S. government has issued and has outstanding Form 1s questioning $134 million of billed costs as of September 30, 2018. They had previously paid us $61 million of the questioned costs related to our services on these contracts. The remaining balance of $73 million as of September 30, 2018 is included on our condensed balance sheet in “Claims and accounts receivable". In addition, we have withheld $26 million from our subcontractors at September 30, 2018 related to these questioned costs, which is included in "Other current liabilities" on our condensed balance sheet.

While we continue to believe that the amounts we have invoiced the U.S. government are in compliance with our contract terms and that recovery is probable, we also continue to evaluate our ability to recover these amounts as new information becomes known. As is common in the industry, negotiating and resolving these matters is often an involved and lengthy process, which sometimes necessitates the filing of claims or other legal action as discussed above. Concurrent with our continued negotiations with the U.S. government, we await the rulings on the filed claims. We are unable to predict when the rulings will be issued or when the matters will be settled or resolved with the U.S. government.

As a result of the Form 1s, and claims discussed above as well as open audits, we have accrued a reserve for unallowable costs of $32 million and $51 million, at September 30, 2018 and December 31, 2017, respectively. The balance at September 30, 2018 is recorded in "Contract liabilities" and "Other liabilities" in the amounts of $17 million and $15 million, respectively. The balance at December 31, 2017 is recorded in "Contract liabilities" and "Other liabilities" in the amounts of $31 million and $20 million, respectively.

Private Security Contractors. Starting in February 2007, we received a series of Form 1s from the DCAA informing us of the U.S. government's intent to deny reimbursement to us under the LogCAP III cost reimbursable contract for amounts related to the use of PSCs by KBR and a subcontractor in connection with its work for KBR providing dining facility services in Iraq between 2003 and 2006. The government challenged $56 million in billings. The government had previously paid $11 million and has withheld payments of $45 million, which as of September 30, 2018 we have recorded as due from the government related to this matter in "Claims and accounts receivable" on our condensed consolidated balance sheets.

On June 16, 2014, we received a decision from the ASBCA which agreed with KBR's position (i) that the LogCAP III contract did not prohibit the use of PSCs to provide force protection to KBR or subcontractor personnel, (ii) that there was a need for force protection and (iii) that the costs were reasonable. The ASBCA also found that the Army breached its obligation to provide force protection. Accordingly, we believe that we are entitled to reimbursement by the Army for the amounts charged by our subcontractors, even if they incurred costs for PSCs. The Army appealed the decision.

On June 12, 2017, we received a second ruling from the ASBCA that we are entitled to recover the withheld costs in the approximate amount of $45 million plus interest related to the use of PSCs. The Army filed a notice of appeal on October 12, 2017 and filed its brief on April 10, 2018. We responded and the Army filed its final brief in June. Oral arguments are expected to occur later this year. At this time, we believe the likelihood that we will incur a loss related to this matter is remote, and therefore we have not accrued any loss provisions related to this matter.

Investigations, Qui Tams and Litigation

The following matters relate to ongoing litigation or federal investigations involving U.S. government contracts. Many of these matters involve allegations of violations of the FCA, which prohibits in general terms fraudulent billings to the U.S. government. Suits brought by private individuals are called "qui tams." We believe the costs of litigation and any damages that may be awarded in the FKTC and Burn Pit matters described below are billable under the LogCAP III. All costs billed under LogCAP III are subject to audit by the DCAA for reasonableness.

First Kuwaiti Trading Company arbitration. In April 2008, FKTC, one of our LogCAP III subcontractors providing housing containers, filed for arbitration with the American Arbitration Association all its claims under various LogCAP III subcontracts. After complete hearings on all claims, the arbitration panel awarded FKTC $17 million plus interest for claims involving damages on lost or unreturned vehicles. In addition, we determined that we owe FKTC $32 million in connection with other subcontracts. We previously paid FKTC $19 million and have recorded $4 million in "Accounts payable" that will be paid on pay-when-paid terms in the contract. The remaining $26 million owed to FKTC under the contract has not been billed to the government and we will not do so until the related claims and disputes between KBR and the government over the FKTC living container contract are resolved (see KBR Contract Claim on FKTC containers below). This amount has been withheld from our subcontractors as described above and also recorded in "Claims and accounts receivable" on our condensed balance sheet as of September 30, 2018. At this time, we believe the likelihood that we would incur a loss related to this matter in excess of the amounts we have accrued is remote.

Burn Pit litigation. Since November 2008, KBR has been served with more than 60 lawsuits in various states alleging exposure to toxic materials resulting from the operation of burn pits in Iraq or Afghanistan in connection with services provided by KBR under the LogCAP III contract. These suits were consolidated in U.S. Federal District Court in Greenbelt, Maryland. The plaintiffs claimed unspecified damages. On January 13, 2017, KBR filed a renewed motion to dismiss and for summary judgment.

On July 19, 2017, the trial court issued its ruling granting KBR’s motions to dismiss on jurisdictional ground and for summary judgment.  In lengthy fact findings, the trial court concluded that the military made all the relevant decisions about the use, location and operation of burn pits.  The plaintiffs filed a notice of appeal, which was denied on June 20, 2018 by the Fourth Circuit Court of Appeals. The plaintiffs filed an application for writ of certiorari to the U.S. Supreme Court on September 7, 2018. We are awaiting the U.S. Supreme Court's decision as to whether it will deny the application or request further briefing. At this time, we believe the likelihood that we would incur a loss related to this matter is remote. As of September 30, 2018, no amounts have been accrued.

Howard qui tam. In March 2011, Geoffrey Howard and Zella Hemphill filed a complaint in the U.S. District Court for the Central District of Illinois alleging that KBR mischarged the U.S. government $628 million for unnecessary materials and equipment. In October 2014, the DOJ declined to intervene and the case was partially unsealed. Discovery is ongoing in this case and is expected to continue into 2019. At this time, we believe the likelihood that we would incur a loss is remote and, as of September 30, 2018, no amounts have been accrued.

DOJ False Claims Act complaint - Iraq Subcontractor. In January 2014, the DOJ filed a complaint in the U.S. District Court for the Central District of Illinois against KBR and two former KBR subcontractors, including FKTC, alleging that three former KBR employees were offered and accepted kickbacks from these subcontractors in exchange for favorable treatment in the award and performance of subcontracts to be awarded during the course of KBR's performance of the LogCAP III contract in Iraq. The complaint alleges that as a result of the kickbacks, KBR submitted invoices with inflated or unjustified subcontract prices, resulting in alleged violations of the FCA and the Anti-Kickback Act. The DOJ's investigation dates back to 2004. We self-reported most of the violations and tendered credits to the U.S. government as appropriate. On May 22, 2014, FKTC filed a motion to dismiss, which the U.S. government opposed. Following the submission of our answer in April 2014, the U.S. government was granted a Motion to Strike certain affirmative defenses in March 2015. We do not believe this limits KBR's ability to fully defend all allegations in this matter. As of September 30, 2018, we have accrued our best estimate of probable loss related to an unfavorable settlement of this matter in "Other liabilities" on our condensed consolidated balance sheets. At this time, we believe the likelihood that we would incur a loss related to this matter in excess of the amounts we have accrued is remote. Discovery in the case has been extended to late 2018 and no trial date has been set.

Other matters

KBR Contract Claim on FKTC containers. KBR previously filed a claim before the ASBCA to recover the costs paid to FKTC to settle its requests for equitable adjustment. The DCMA had disallowed the majority of those costs. Those contract claims were stayed in 2013 at the request of the DOJ so that they could pursue the FCA case referenced above. Those claims were

reinstated in 2016. We tried our contract appeal in September 2017. Final briefing was filed in early 2018, and closing arguments were held on March 22, 2018. We expect to receive a ruling in late 2018.

Litigation and regulatory matters related to the Company’s restatement of its 2013 annual financial statements

Butorin v. Blount et al, is a May 2014 shareholder derivative complaint pending in the U.S. District Court of Delaware and filed on behalf of the Company naming certain current and former members of the Company's board of directors as defendants and the Company as a nominal defendant. The complaint alleges that the named directors breached their fiduciary duties by permitting the Company's internal controls to be inadequate. This case was dismissed on August 31, 2018.

We also received requests for information and a subpoena for documents from the SEC in 2014 regarding the restatement of our 2013 annual financial statements. We reached a settlement with the SEC in July 2018, which did not have a material impact on our financial statements.

Other matters

Unaoil Investigation. The DOJ, SEC, and the SFO are conducting investigations of Unaoil, a Monaco based company, in relation to international projects involving several global companies, including KBR, whose interactions with Unaoil are a subject of those investigations. KBR believes it is cooperating with the DOJ, SEC, and the SFO in their investigations, including through the voluntary submission of information and responding to formal document requests.

In re KBR, Inc. Securities Litigation. On October 20, 2017, lead plaintiffs filed an amended consolidated complaint asserting violations of the federal securities laws in connection with KBR's disclosures associated with the SFO's investigations of KBR and its affiliates relating to Unaoil. The Company and individual defendants filed a motion to dismiss the lawsuit on December 4, 2017. Briefing on the motion to dismiss was completed on February 19, 2018. Defendants' motion to dismiss was granted on August 31, 2018, and this matter is now concluded.

Tisnado vs DuPont, et al. In May 2016, KBR was served with a Fourth Amended Petition in Intervention and was brought into a lawsuit which was originally filed on November 14, 2014, in the 11th Judicial District Court of Harris County, Texas. This suit was brought by the family members of persons who died in an incident at the DuPont plant in LaPorte, Texas. We reached a settlement with the plaintiffs in 2018. This settlement was covered by insurance and did not have a material impact to our financial statements. This matter is now resolved.

PEMEX and PEP arbitration

On April 6, 2017, we entered into a settlement agreement with PEMEX and PEP related to a dispute from 2004. The settlement provided for a cash payment to Commisa of $435 million, payment by PEP of all VAT related to the settlement amount and mutual dismissals and releases of all claims related to the EPC 1 project. This matter is resolved and all amounts were paid by PEP in April 2017. As a result of the final settlement, we recognized additional revenues and gross profit of $35 million for the nine months ended September 30, 2017.

Share Repurchases

Authorized Share Repurchase Program

On February 25, 2014, our Board of Directors authorized a plan to repurchase up to $350 million of our outstanding common shares, which replaced and terminated the August 26, 2011 share repurchase program. The authorization does not obligate the

Company to acquire any particular number of common shares and may be commenced, suspended or discontinued without prior notice. The share repurchases are intended to be funded through the Company’s current and future cash and the authorization does not have an expiration date.

Withheld to Cover Program

In addition to the plans above, we also have in place a "withheld to cover" program, which allows us to withhold common shares from employees in connection with the settlement of income tax and related benefit withholding obligations arising from the issuance of share based equity awards under the KBR, Inc. 2006 Stock and Incentive Plan.

The table below presents information on our share repurchases activity under these programs:

Earnings Per Share [Abstract]

Income per Share

Income per Share

Basic income per share is based upon the weighted average number of common shares outstanding during the period. Dilutive income per share includes additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued using the treasury stock method.

A reconciliation of the number of shares used for the basic and diluted income per share calculations is as follows:

	Three Months Ended September 30,		Nine Months Ended September 30,
Shares in millions	2018	2017	2018	2017
Basic weighted average common shares outstanding	141	140	140	141
Stock options and restricted shares	—	—	1	—
Diluted weighted average common shares outstanding	141	140	141	141

For purposes of applying the two-class method in computing income per share, there were $0.4 million and $1.5 million net earnings allocated to participating securities, or a negligible amount per share and $0.01 per share, for the three and nine months ended September 30, 2018, respectively. Net earnings allocated to participating securities for the three and nine months ended September 30, 2017 were $0.3 million and $1.1 million, respectively, or a negligible amount per share. The diluted income per share calculation did not include 1.4 million and 1.6 million antidilutive weighted average shares for the three and nine months ended September 30, 2018, respectively. The diluted income per share calculation did not include 1.9 million and 2.2 million antidilutive weighted average shares for the three and nine months ended September 30, 2017, respectively.

Financial Instruments and Risk Management

Financial Instruments and Risk Management

Foreign currency risk. We conduct business globally in numerous currencies and are therefore exposed to foreign currency fluctuations. We may use derivative instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. We do not use derivative instruments for speculative trading purposes. We generally utilize foreign exchange forwards and currency option contracts to hedge exposures associated with forecasted future cash flows and to hedge exposures present on our balance sheet.

As of September 30, 2018, the gross notional value of our foreign currency exchange forwards and option contracts used to hedge balance sheet exposures was $54 million, all of which had durations of 9 days or less. We also had approximately $110 million (gross notional value) of cash flow hedges which had durations of approximately 22 months or less. The cash flow hedges are primarily related to the British Pound and Australian Dollar. The Australian Dollar hedges are primarily utilized to reduce the volatility of cash flows associated with the forecasted funding of JKC in Australian Dollars.

The fair value of our balance sheet and cash flow hedges included in "Other current assets" and "Other current liabilities" on our condensed consolidated balance sheets was immaterial at September 30, 2018 and December 31, 2017. The fair values of these derivatives are considered Level 2 under ASC 820, Fair Value Measurement, as they are based on quoted prices directly observable in active markets.

The following table summarizes the recognized changes in fair value of our balance sheet hedges offset by remeasurement of balance sheet positions. These amounts are recognized in our condensed consolidated statements of operations for the periods presented. The net of our changes in fair value of hedges and the remeasurement of our assets and liabilities is included in "Other non-operating income (expense)" on our condensed consolidated statements of operations.

Subsequent Event

The Company uses interest rate swaps to reduce interest rate risk and to manage net interest expense.  On October 10, 2018 we entered into interest rate swap agreements with a notional value of $500 million to manage the interest rate exposure on our floating rate loans.  By entering into swap agreements, the Company converted the LIBOR rate based liability into a fixed rate liability for a four year period.  Under the swap agreements, the Company receives one month LIBOR rate and pays monthly a fixed rate of 3.055% for the term of the swaps.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedge Activities. This ASU is intended to improve and simplify accounting rules around hedge accounting. This ASU is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. Early adoption is permitted. We do not expect adoption of this ASU to be material to our ongoing financial reporting or on known trends, demand, uncertainties and events in our business.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted, for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not expect adoption of this ASU to be material to our ongoing financial reporting or on known trends, demands, uncertainties and events in our business.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments. This ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable supportable forecast and is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted for annual periods after December 15, 2018, including interim periods within those annual periods. We are currently in the process of assessing the impact of this ASU on our financial statements. We have not yet determined the effect of the standard on our ongoing financial reporting or the future impact of adoption on known trends, demands, uncertainties and events in our business.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases with terms longer than 12 months. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. This ASU is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. Early adoption is permitted. We have developed a detailed plan to implement the new standard and, through a cross functional team, are assessing contractual arrangements that may qualify as leases under the new standard. The impact of the new standard will be a material increase to right of use assets and lease liabilities, primarily as a result of operating leases currently not recognized on our consolidated balance sheet.

Accounting Policies [Abstract]

Principles of consolidation

Principles of Consolidation

Our condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR and our wholly owned and majority-owned subsidiaries and VIEs of which we are the primary beneficiary. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. See Note 11 to our condensed consolidated financial statements for further discussion on our equity investments and VIEs. The cost method is used when we do not have the ability to exert significant influence. All material intercompany balances and transactions are eliminated in consolidation.

Amounts classified as "Costs and estimated earnings in excess of billings on uncompleted contracts" and "Billings in excess of costs and estimated earnings on uncompleted contracts" on the consolidated balance sheets of our Annual Report on Form 10-K for the year ended December 31, 2017 have been reclassified as "Contract assets" and "Contract liabilities" on the condensed consolidated balance sheets.

We have evaluated all events and transactions occurring after the balance sheet date but before the financial statements were issued and have included the appropriate disclosures.

Use of estimates

Use of Estimates

The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses

during the reporting period. Actual results could differ from those estimates. Areas requiring significant estimates and assumptions by our management include but are not limited to the following:

• project revenues, costs and profits on engineering and construction contracts, including recognition of estimated losses on uncompleted contracts

• project revenues, award fees, costs and profits on government services contracts

• provisions for uncollectible receivables

• provisions for client claims and recoveries of costs from subcontractors, vendors and others

• provisions for income taxes and related valuation allowances and tax uncertainties

• recoverability of goodwill

• recoverability of other intangibles and long-lived assets and related estimated lives

• recoverability of equity method and cost method investments

• valuation of pension obligations and pension assets

• accruals for estimated liabilities, including litigation accruals

• consolidation of VIEs

• valuation of share-based compensation

• valuation of assets and liabilities acquired in business combinations

We classify revenue contract liabilities as current or noncurrent based on the timing of when we expect to recognize revenue. The noncurrent portion of contract liabilities is included in "Other liabilities" in our condensed consolidated balance sheets. If the underlying estimates and assumptions upon which the financial statements are based change in the future, actual amounts may differ from those included in the accompanying condensed consolidated financial statements.

Revenue Recognition

Revenue Recognition

Revenue is measured based on the amount of consideration specified in a contract with a customer. Revenue is recognized when and as our performance obligations under the terms of the contract are satisfied, which generally occurs with the transfer of control of the goods or services to the customer.

To determine the proper revenue recognition method for contracts, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more

than one performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate a combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, which is mainly because we provide a significant service of integrating a complex set of tasks and components into a single project or capability. Contracts that cover multiple phases of the product lifecycle (development, construction and maintenance & support) are typically considered to have multiple performance obligations even when they are part of a single contract.

For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. In cases where we do not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We provide product warranties to customers that are included in the sale and are not priced or sold separately or do not provide customers with a service in addition to assurance of compliance with agreed-upon specifications. We do not consider these types of warranties to be separate performance obligations.

The following is a description of the principal activities from which we generate revenues by reportable segment:

Government Services

For most of government services, the customer contracts with us to provide support solutions to defense, space, aviation and other programs and missions through long-term service contracts. The performance obligations related to these long-term service contracts are primarily created through the issuance of task orders by the customer because a service contract generally does not meet the criteria to be considered a contract under ASC 606 since it does not obligate the customer to issue any task orders and could be canceled without substantive penalty under termination for convenience clauses. Accordingly, each task order releases us to perform specific portions of the overall scope in the service contract and is typically accounted for as a separate contract because the task order establishes the enforceable rights and obligations and payment terms. Task orders can include option periods that may be approved by the customer at a later date depending on the customer's future needs and budget availability.

Many of our government services contracts include variable consideration consisting of base fees (a profit percentage applied to our target cost) or award fees (additional consideration based on performance criteria, subject to final customer approval). Variable consideration can also arise from modifications to the scope of services resulting in unapproved change orders or customer claims. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted) that is reasonably available to us.

Many of our government services contracts are for labor at agreed hourly rates on a cost reimbursable basis to the customer. These contracts are accounted for as a series of distinct services because (a) the labor is provided as a continuous service, (b) each time increment of labor provided is distinct, (c) the nature of the services provided is substantially the same, and (d) the pattern of transfer is the same. In these types of contracts, the entire amount of consideration is recognized as labor is provided.

We also enter into base operations support contracts to provide the resources to operate bases, installations, camps, and stations of military departments. Our base operations support contracts are either fixed price contracts or cost reimbursable contracts. For fixed price contracts, we bill the customer a fixed monthly fee and recognize revenue over time on a straight-line basis where our level of effort remains substantially the same from month to month or where that is not the case, using a cost-to-cost input measure of progress as services are provided. For cost reimbursable contracts, we bill the customer all direct costs incurred each month plus an agreed provisional rate for overhead and fee, which are finalized at a later date. Revenue for cost reimbursable contracts is recognized as the direct costs are incurred and billed because the base operations represent a series of distinct services and the direct costs are consistent with our level of effort each month. For the purpose of revenue recognition of the variable elements of the contracts, we apply the variable consideration considerations described above.

Revenue on our other types of government services contracts is primarily recognized over time using the cost-to-cost input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress because it best depicts the transfer of assets to the customer, which occurs as we incur costs on the contracts. Contract costs include actual direct project costs incurred and an allocation of our indirect costs.

Under the typical payment terms of our government services contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones.

Hydrocarbons Services

For most of our hydrocarbons services projects, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability and are therefore accounted for as single performance obligations.

It is common for our hydrocarbons services contracts to contain incentive fees, performance bonuses, penalties (liquidated damages) or other provisions, including claims and change orders that may either increase or decrease the transaction price. Incentives and other performance bonuses generally are awarded upon achievement of certain performance metrics, program milestones or cost targets. Liquidated damage penalties in our contracts are generally capped at a percentage of the total contract value. Liquidated damages may be related to schedule delays, typically calculated based on a daily rate, or tied to performance guarantees.

Substantially all of our performance obligations related to hydrocarbons services contracts are satisfied over time as work progresses due to the continuous transfer of control to the customer. Typically, revenue is recognized over time using the cost-to-cost input measure to measure progress because it best depicts the transfer of goods and services to the customer, which occurs as we incur costs on our contracts. Contract costs include all direct material and labor costs and those indirect costs related to contract performance. Indirect costs, included in cost of revenues, include charges for such items as facilities, engineering, project management, quality control, bids and proposals and procurement.

Under the typical payment terms of our hydrocarbons services contracts, the customer makes advance payments as well as interim payments as work progresses. The advance payment generally is not considered a significant financing component as we normally expect to recognize the advance payments in revenue within a year of receipt as work progresses on the related performance obligation.

Technology

Our technology contracts consist primarily of licensing, basic engineering design (together, the "LBED"), proprietary equipment ("PEQ") or catalyst contracts. LBED contracts are combined into one performance obligation as they are entered into at the same time and the licensed technology requires engineering and design. We may further combine LBED and PEQ contracts into one performance obligation if the contracts were negotiated as a package with a single commercial objective, and the customer contracts with us to provide a significant service of integrating these distinct goods and services into a single project or capability.

It is common for our technology contracts to contain variable consideration including contingent milestone payments and penalties (liquidated damages) that may increase or decrease the transaction price. Contingent milestone payments are primarily related to decisions made by the customer after the LBED has been completed, such as a go or no-go decision on the project. Liquidated damage penalties in our technology contracts are typically triggered by late delivery and are calculated based on a weekly rate and are capped at a percentage of the total contract value.

Substantially all of our performance obligations related to technology contracts are satisfied over time as work progresses. Typically, revenue is recognized over time using the cost-to-cost input measure to measure progress because it best depicts the transfer of assets to the customer, which occurs as we incur costs on our contracts. Contract costs include all direct material and labor costs and those indirect costs related to contract performance and are recognized as the performance obligation is satisfied.

Under the typical payment terms of our technology contracts, the customer makes advance payments as well as interim payments as work progresses and certain progress milestones are met. The advance payment generally is not considered a significant financing component as we normally expect to recognize the advance payments in revenue within a year of receipt as work progresses on the related performance obligation.

Contract Estimates

Contract Modifications

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment.

As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly through a Company-wide disciplined project review process in which management reviews the progress and execution of our performance obligations and the estimate at completion (EAC). As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule and the related changes in estimates of revenues and costs. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer, among other variables.

We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the period it is identified.

Contracts are often modified to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

We account for contract modifications as a separate contract when the modification results in the promise to deliver additional goods or services that are distinct and the increase in price of the contract is for the same amount as the stand-alone selling price of the additional goods or services included in the modification.

We estimate variable consideration at the most likely amount to which we expect to be entitled. Any variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, performance and any other information (historical, current, and forecasted) that is reasonably available to us.

We allocate variable consideration entirely to a performance obligation or to a distinct good or service within a performance obligation if it relates specifically to our efforts to satisfy the performance obligation or transfer the distinct good or service, and the allocation represents the amount of consideration to which we expect to be entitled.

Account receivable

Accounts receivable

Accounts receivable are recorded based on contracted prices when we obtain an unconditional right to payment under the terms of our contracts.

We establish an allowance for doubtful accounts based on the assessment of our clients' willingness and ability to pay. In addition to such allowances, there are often items in dispute or being negotiated that may require us to make an estimate as to the ultimate outcome. Past due receivable balances are written off when our internal collection efforts have been unsuccessful in collecting the amounts due.

Contract assets and liabilities

Contract assets and liabilities

Billing practices are governed by the contract terms of each project based upon costs incurred, achievement of milestones or pre-agreed schedules. Billings do not necessarily correlate with revenue recognized using the cost-to-cost method of revenue recognition. Contract assets include unbilled amounts typically resulting from revenue under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to

payment is not unconditional. Contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue.

Retainage, included in contract assets, represents the amounts withheld from billings by our clients pursuant to provisions in the contracts and may not be paid to us until the completion of specific tasks or the completion of the project and, in some instances, for even longer periods. Retainage may also be subject to restrictive conditions such as performance guarantees.

Our contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. We classify contract liabilities as current or noncurrent based on the timing of when we expect to recognize revenue. The noncurrent portion of contract liabilities is included in "Other liabilities" in our condensed consolidated balance sheets.

Acquisition and integration related costs

Acquisition and integration related costsAcquisition and integration related costs consist of third party transaction expenses representing legal, consulting and investment banking-related costs that are direct, incremental costs incurred prior to the closing of an acquisition and direct, incremental costs incurred to integrate the operations of newly acquired businesses into the Company's existing infrastructure as well as other initiatives to combine the newly merged companies into new infrastructure.

Schedule of pro forma information

The following supplemental pro forma condensed consolidated results of operations assume that SGT and the Aspire Defence subcontracting joint ventures had been acquired as of January 1, 2017. The supplemental pro forma information was prepared based on the historical financial information of SGT and the Aspire Defence subcontracting joint ventures and has been adjusted to give effect to pro forma adjustments that are both directly attributable to the transaction and factually supportable. Pro forma adjustments were primarily related to the amortization of intangibles, interest on borrowings related to the acquisitions, and the reclassification of the gain on consolidation of the Aspire entities to January 1, 2017. Accordingly, this supplemental pro forma financial information is presented for informational purposes only and is not necessarily indicative of what the actual results of operations of the combined company would have been had the acquisitions occurred on January 1, 2017, nor is it indication of future results of operations.

As a result of the adoption of ASC 606 on January 1, 2018, unbilled accounts receivable is classified in "Accounts receivable" in our condensed consolidated balance sheets as it represents the amounts that have been recorded in revenue based on contracted prices for which we have obtained an unconditional right to payment under the terms of our contracts. Retainage is now recorded in "Contract Assets" in our condensed consolidated balance sheets when the right to payment of the retainage is conditional under the terms of our contracts. Prior to the adoption of ASC 606, unbilled accounts receivables were classified as "Costs and estimated earnings in excess of billings on uncompleted contracts" and retainage was classified within "Accounts receivable".

Schedule of Contact Assets and Liabilities

Our contract assets by business segment are as follows:

	September 30,		December 31,

Government Services	$	118	$	274	$	(156	)	(57	)%

Non-strategic Business	—		—		—			N/A
Total	$	214	$	383	$	(169	)	(44	)%

The decrease in contract assets was primarily caused by the initial adjustment due to the adoption of ASC 606, offset by normal business operations and the acquisition of $21 million of contract assets from the purchase of SGT as described in Note 5 to our condensed consolidated financial statements.

Our contract liabilities by business segment are as follows:

	September 30,		December 31,
Dollars in millions	2018		2017		$ Change		% Change
Government Services	$	240	$	85	155		182	%

Non-strategic Business	5		8		(3	)	(38	)%
Total	$	464	$	368	96		26	%

The increase in contract liabilities was primarily related to the acquisition of $161 million of contract liabilities associated with the Aspire Defence project joint ventures, partially offset by normal business operations and the recognition of the incentive fee associated with an Australian LNG project.

Revenue recognized for the nine months ended September 30, 2018 that was included in the contract liability balance at December 31, 2017 was $247 million.

(a) As further discussed in Note 1 to our condensed consolidated financial statements, deferred construction income in the amount of $87 million previously recorded in "Equity in and advance to unconsolidated affiliates" was reversed and included in the cumulative effect adjustment as a result of the early adoption of ASC 606 by the Aspire Defence project joint ventures.

(b) From 2014 through 2017, we received cash dividends in excess of the carrying value of one of our unconsolidated joint ventures. We have no obligation to return any portion of the cash dividends received. We recorded excess dividends as "Deferred income from unconsolidated affiliates" on our condensed consolidated balance sheets and recognized these dividends as earnings are generated by the investment. As further discussed in Note 1 to our condensed consolidated financial statements, the adoption of ASC Topic 606 by this unconsolidated joint venture resulted in the reversal of the "Deferred income from unconsolidated affiliates" balance of $101 million in our condensed consolidated balance sheets as of December 31, 2017 in the cumulative effect adjustment of the change in accounting policy.

(c) In 2018, investments included a $257 million investment to fund JKC.
