Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements were prepared using generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, these financial statements do not include all information or notes required by generally accepted accounting principles for annual financial statements and should be read together with our 2022 Annual Report on Form 10-K. The condensed consolidated financial statements include all normal and recurring adjustments necessary to present fairly our financial position as of September 29, 2023, the results of our operations for the three and nine months ended September 29, 2023 and September 30, 2022, respectively, and our cash flows for the nine months ended September 29, 2023 and September 30, 2022, respectively. Certain amounts in prior periods have been reclassified to conform with current period presentation. 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. We generally 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. Our significant accounting policies are detailed in "Note 1. Significant Accounting Policies" of our 2022 Annual Report on Form 10-K. 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. Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR, Inc. and the subsidiaries it controls, including VIEs where it is the primary beneficiary (collectively, the "Company," "KBR", "we", "us" or "our"). We account for investments over which we have significant influence, but not a controlling financial interest, using the equity method of accounting. See Note 7 "Equity Method Investments and Variable Interest Entities" to our condensed consolidated financial statements for further discussion of our equity investments and VIEs. All material intercompany balances and transactions are eliminated in consolidation. Basis of Presentation On December 13, 2022, the Board of Directors approved a change in the fiscal year end from a calendar year ending on December 31 to a 52 – 53 week year ending on the Friday closest to December 31, effective as of the commencement of the Company's fiscal year on January 1, 2023. In a 52 week fiscal year, each of the Company’s quarterly periods will comprise 13 weeks. The additional week in a 53 week fiscal year is added to the fourth quarter, making such quarter consist of 14 weeks. The Company’s first 53 week fiscal year will occur in fiscal year 2024. The Company made the fiscal year change on a prospective basis and will not adjust operating results for prior periods. The change will impact the prior year comparability of each of the fiscal quarters and the annual period for the year ending December 31, 2023, however, the impact will not be material. The Company believes this change will improve comparability between periods by eliminating the year-over-year variability in calendar month productive days and provide a more consistent reporting cadence for operational leaders to aid in strategic decision making. Due to this change in fiscal year, our third fiscal quarter ended on September 29 in 2023 as compared to September 30 in 2022. The three months ended September 29, 2023 and September 30, 2022 contained 90 days and 91 days, respectively. The nine months ended September 29, 2023 and September 30, 2022 contained 272 days and 273 days, respectively. As a result of our change in a fiscal year end, goodwill will be tested annually for possible impairment as of the first day of our fourth quarter each fiscal year, and on an interim basis when indicators of possible impairment exist. Impact of Adoption of New Accounting Standards Effective January 1, 2023, we adopted ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires entities to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . The update will generally result in an entity recognizing contract assets and contract liabilities at amounts consistent with those recorded by the acquiree immediately before the acquisition date rather than at fair value. The adoption of this standard did not have an impact on our condensed consolidated financial statements. However, the ultimate impact is dependent upon the size and frequency of future acquisitions. Additional Balance Sheet Information Other Current Assets The components of other current assets on our condensed consolidated balance sheets as of September 29, 2023, and December 31, 2022, are presented below: September 29, December 31, Dollars in millions 2023 2022 Note hedge derivative asset $ 335 $ — Prepaid expenses 63 67 Value-added tax receivable 33 24 Advances to subcontractors 19 18 Other miscellaneous assets 73 55 Total other current assets $ 523 $ 164 Other Current Liabilities The components of other current liabilities on our condensed consolidated balance sheets as of September 29, 2023, and December 31, 2022, are presented below: September 29, December 31, Dollars in millions 2023 2022 Embedded derivative liability $ 335 $ — Reserve for estimated losses on uncompleted contracts 16 17 Value-added tax payable 41 32 Dividend payable 19 17 Other miscellaneous liabilities 92 106 Total other current liabilities $ 503 $ 172

We recognized revenue from performance obligations satisfied in previous periods for such matters of $8 million for the nine months ended September 29, 2023, and $26 million and $32 million for the three and nine months ended September 30, 2022, respectively. On September 29, 2023, we had $12.1 billion of transaction price allocated to remaining performance obligations. We expect to recognize approximately 36% of our remaining performance obligations as revenue within one year, 39% in years two through five and 25% thereafter. Revenue associated with our remaining performance obligations to be recognized beyond one year includes performance obligations primarily related to the Aspire Defence project, which has contract terms extending through 2041. Remaining performance obligations do not include variable consideration that was determined to be constrained as of September 29, 2023. We recognized revenue of $183 million and $177 million for the nine months ended September 29, 2023 and September 30, 2022, respectively, which was previously included in the contract liability balance at the beginning of each period.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions VIMA Group On August 2, 2022, we acquired VIMA Group, a U.K.-based leading provider of digital transformation solutions to defense and other public sector clients. VIMA Group is reported within our GS business segment. We accounted for this transaction as an acquisition of a business using the acquisition method under Business Combinations (Topic 805) . The agreed-upon purchase price for the acquisition was $82 million. The purchase price consisted of cash paid at closing of $75 million, subject to certain working capital and other closing adjustments, $4 million of deferred consideration and contingent consideration with an estimated fair value of $3 million that was contingent upon the achievement of certain performance targets from closing through December 31, 2022. As the targets were not met, no consideration was paid and we recorded a benefit of $3 million in our consolidated statements of operations for the year ended December 31, 2022. We recognized $2 million as an intangible backlog asset, $11 million in customer relationships, $3 million in net working capital, $2 million in deferred income tax liability and $68 million of goodwill arising from the acquisition, which relates primarily to future growth opportunities. The purchase price allocation for the business combination is considered final. For U.S. tax purposes, the transaction is treated as a stock deal. As a result, there is no step-up in tax basis in the individual assets and liabilities acquired and the goodwill recognized is not deductible for tax purposes.

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, weather and ongoing resolution of legacy projects and legal matters, including any new or ongoing disputes with our business partners and others in our supply chain. We generally 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. Sanctions and trade control measures were implemented against Russia due to the ongoing conflict between Russia and Ukraine. These measures impacted our ability to operate in the region as we carried out efforts to wind down our operations in Russia. During the nine months ended September 30, 2022, we recognized an unfavorable change of $22 million in gross profit and incurred $6 million in severance and asset impairments costs associated with exiting commercial projects in Russia. During the nine months ended September 30, 2022, within our STS business segment, we recognized a non-cash charge to equity in earnings of unconsolidated affiliates of $137 million as a result of changes in estimates on the Ichthys LNG Project in connection with a settlement agreement (the “Subcontractor Settlement Agreement”) entered into to resolve outstanding claims and disputes between JKC and the consortium of subcontractors. During the three and nine months ended September 30, 2022, within our GS business segment, we recorded a charge to equity in earnings of unconsolidated affiliates on a joint venture acquired from a historical GS acquisition of $10 million based on our funding obligations of projected losses. During the three and nine months ended September 30, 2022, within our GS business segment, we recognized a net favorable change in gross profit of $10 million and $1 million, respectively, associated with changes in estimates related to ongoing contract negotiations, some of which have been resolved.

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 partnerships, corporations and undivided interests 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: Nine Months Ended September 29, Year Ended December 31, 2023 2022 Dollars in millions Beginning balance at January 1, $ 188 $ 576 Equity in earnings (losses) of unconsolidated affiliates (a) 78 (80) Distributions of earnings of unconsolidated affiliates (b) (46) (53) Payments from unconsolidated affiliates, net (13) (14) (Return of) investments in equity method investment, net (c) (61) (198) Sale of equity method investment (d)(a) — (31) Foreign currency translation adjustments — (15) Other (e) 47 3 Ending balance $ 193 $ 188 (a) During 2022, a non-cash charge of $137 million was recorded for settlement agreements associated with the Ichthys LNG project. Additionally, during the third quarter of 2022, we recorded a charge against a joint venture acquired from a historical GS acquisition of $10 million based on our funding obligations of projected losses. In the fourth quarter of 2022, we divested this joint venture and recorded an incremental loss on sale of $3 million. The remaining equity in earnings (losses) of unconsolidated affiliates in 2023 and 2022 is related to normal activities within our other joint ventures. (b) In the normal course of business, our joint ventures will declare a distribution in the current quarter that is not paid until the subsequent quarter. As such, the distributions declared during the current quarter may not agree to the distributions of earnings from unconsolidated affiliates on our condensed consolidated statements of cash flows. (c) During the nine months ended September 29, 2023, we received a return of investment from JKC of approximately $61 million related to the second payment received from the Subcontractor Settlement Agreement. For the year ended December 31, 2022, we received a return of investment from JKC of approximately $190 million related to the first payment from the Subcontractor Settlement Agreement and from BRIS of $10 million as our cumulative distributions from inception of the joint venture exceeded our cumulative earnings. (d) During the first quarter of 2022, we sold two of our four U.K. Road investments. The carrying value of our investment was $22 million. We received $18 million in cash proceeds and the purchaser agreed to assume the $4 million of consortium relief. In the second quarter of 2022, we sold an additional U.K. Road investment with a carrying value of $19 million and recorded a gain of approximately $16 million upon receipt of $35 million in cash proceeds, in addition to receipt of $2 million of deferred consideration from the first quarter 2022 sales. (e) During the nine months ended September 29, 2023, Other included a net liability position of $52 million related to our investment in JKC. The net liability position is attributed to our proportionate share of the provision that JKC continues to maintain for the paint and insulation claims against the insurer and paint manufacturer net of expected tax benefits. Related Party Transactions We often provide engineering, construction management and other subcontractor services to our unconsolidated joint ventures, and our revenues include amounts related to these services. For the nine months ended September 29, 2023 and September 30, 2022, respectively, our revenues included $390 million and $295 million related to the services we provided primarily to the Aspire Defence Limited joint venture within our GS business segment and a joint venture within our STS business segment. Amounts included in our condensed consolidated balance sheets related to services we provided to our unconsolidated joint ventures as of September 29, 2023, and December 31, 2022 are as follows: September 29, December 31, Dollars in millions 2023 2022 Accounts receivable, net of allowance for credit losses $ 82 $ 56 Contract assets $ — $ 2 Other current assets $ — $ 12 Contract liabilities $ 79 $ 39

See Note 18 "Cash Election and Repurchase of Convertible Notes" for additional information regarding these transactions. Senior Credit Facility We entered into Amendment No. 10 on July 26, 2023, to our existing Credit Agreement, dated as of April 25, 2018, as amended ("Credit Agreement"), consisting of a $1 billion revolving credit facility (the "Revolver"), a Term Loan A ("Term Loan A") with debt tranches denominated in U.S. dollars and British pound sterling and a Term Loan B ("Term Loan B") ("Senior Credit Facility"). Amendment No. 10 provided for an additional $200 million loan tranche under Term Loan A. We borrowed the full $200 million principal amount available under this additional loan tranche, and this $200 million borrowing was applied as a partial repayment of the outstanding amounts of principal and accrued interest under the Revolver. We had borrowings of $430 million and repayments of $270 million on our Senior Credit Facility that occurred during the nine months ended September 29, 2023. Of these borrowings on our Senior Credit Facility, we borrowed $255 million on June 16, 2023 to fund our repurchase of a portion of Convertible Notes and termination of the corresponding portions of the Note Hedge Transactions and Warrant Transactions. See Note 18 "Cash Election and Repurchase of Convertible Notes" for additional information. The interest rates with respect to the Revolver and Term Loan A are based on, at the Company's option, the applicable adjusted reference rate plus an additional margin or base rate plus additional margin. The interest rate with respect to the Term Loan B is SOFR plus 2.75% plus an additional margin, per annum. Additionally, there is a commitment fee applicable to available amounts under the Revolver. The details of the applicable margins and commitment fees under the amended Senior Credit Facility are based on the Company's consolidated net leverage ratio as follows: Revolver and Term Loan A Consolidated Net Leverage Ratio Reference Rate (a) Base Rate Commitment Fee Greater than or equal to 4.25 to 1.00 2.25 % 1.25 % 0.33 % Less than 4.25 to 1.00 but greater than or equal to 3.25 to 1.00 2.00 % 1.00 % 0.30 % Less than 3.25 to 1.00 but greater than or equal to 2.25 to 1.00 1.75 % 0.75 % 0.28 % Less than 2.25 to 1.00 but greater than or equal to 1.25 to 1.00 1.50 % 0.50 % 0.25 % Less than 1.25 to 1.00 1.25 % 0.25 % 0.23 % (a) The reference rate for the Revolver and the U.S. dollar tranches of Term Loan A is SOFR plus 10 bps Credit Spread Adjustment and the British pound sterling tranche is SONIA plus 12 bps Credit Spread Adjustment. Term Loan A provides for quarterly principal payments of 0.625% of the aggregate principal amount that commenced with the fiscal quarter ended March 31, 2022, increasing to 1.25% starting with the quarter ending March 29, 2024. Term Loan B provides for quarterly principal payments of 0.25% of the initial aggregate principal amounts that commenced with the fiscal quarter ended June 30, 2020. Term Loan A and the Revolver mature in November 2026 and Term Loan B matures in February 2027. The Senior Credit Facility contains financial covenants of a maximum consolidated net leverage ratio and a consolidated interest coverage ratio (as such terms are defined in the Senior Credit Facility). Our consolidated net leverage ratio as of the last day of any fiscal quarter may not exceed 4.50 to 1 through 2022, reducing to 4.25 to 1 in 2023 and 4.00 to 1 in 2024 and thereafter. Our consolidated interest coverage ratio may not be less than 3.00 to 1 as of the last day of any fiscal quarter. As of September 29, 2023, we were in compliance with our financial covenants related to our debt agreements. Convertible Senior Notes Convertible Senior Notes. On November 15, 2018, we issued and sold $350 million of 2.50% Convertible Senior Notes due 2023 (the "Convertible Notes") pursuant to an indenture between us and Citibank, N.A., as trustee. The Convertible Notes are senior unsecured obligations and bear interest at 2.50% per year, and interest is payable on May 1 and November 1 of each year. The Convertible Notes mature on November 1, 2023, and may not be redeemed by us prior to maturity. As such, the Convertible Notes are classified as current liabilities on our condensed consolidated balance sheets as of September 29, 2023. In April 2023, we elected cash as the settlement method to settle the principal and any excess value upon early conversion or maturity of the Convertible Notes. On June 1, 2023, we entered into privately-negotiated transactions to repurchase $100 million in principal amount of the outstanding Convertible Notes (the “Convertible Notes repurchase”), using funds borrowed under our Revolver to pay the purchase price. Concurrent with the Convertible Notes repurchase, we entered into agreements with the option counterparties to terminate the corresponding portions of the Note Hedge Transactions and Warrant Transactions (collectively, the "Unwind Agreements"). See Note 18 "Cash Election and Repurchase of Convertible Notes" for additional information regarding these transactions. On August 23, 2023, we declared a quarterly cash dividend of $0.135 per Common Share, which exceeded our per share dividend threshold and adjusted the conversion rate to 39.6890 Common Shares per $1,000 principal amount of Convertible Notes at a strike price of $25.20. Convertible Notes Call Spread Overlay. Concurrent with the issuance of the Convertible Notes, we entered into privately negotiated convertible note hedge transactions (the "Note Hedge Transactions") and warrant transactions (the "Warrant Transactions") with the option counterparties. These transactions represent a call spread overlay, whereby the cost of the Note Hedge Transactions we purchased to cover the cash outlay upon conversion of the Convertible Notes was reduced by the sales price of the Warrant Transactions. The updated strike price of the net-share settled warrants as of September 29, 2023 was $39.52. The Note Hedge Transactions and the Warrant Transactions are separate transactions, in each case entered into by us with the option counterparties, and are not part of the terms of the Convertible Notes and will not affect any holder's rights under the Convertible Notes . As of September 29, 2023, the if-converted value of the Convertible Notes, based on the closing share price, exceeded the remaining $250 million principal amount by approximately $335 million. The incremental value over the principal amount would be fully offset by the cash delivered from the Note Hedge Transactions. However, the counterparties holding the warrants also have the right to purchase the total convertible number of shares at the current conversion rate at a strike price of $39.52 resulting in value of $193 million that would have been delivered to the counterparties as of September 29, 2023. The Convertible Notes matured November 1, 2023, with principal amounts totaling $250 million with the aggregate cash conversion consideration totaling $593 million. Concurrently, the Note Hedge Transactions were settled with payments to the Company totaling $343 million. The aggregate cash conversion consideration of $593 million was fulfilled with proceeds received from Note Hedge Transactions totaling $343 million, a $200 million borrowing on our Revolver and $50 million in available cash. The Warrant Transactions remain outstanding as of November 1, 2023. Senior Notes On September 30, 2020, we issued and sold $250 million aggregate principal amount of 4.750% Senior Notes due 2028 (the "Senior Notes") pursuant to an indenture among us, the guarantors party thereto and Citibank, N.A., as trustee. The Senior Notes are senior unsecured obligations and are fully and unconditionally guaranteed by each of our existing and future domestic subsidiaries that guarantee our obligations under the Senior Credit Facility and certain other indebtedness. Interest is payable semi-annually in arrears on March 30 and September 30 of each year, beginning on March 30, 2021, and the principal is due on September 30, 2028. At any time prior to September 30, 2023, we could have redeemed all or part of the Senior Notes at a redemption price equal to 100% of the principal amount of the Senior Notes redeemed, plus accrued and unpaid interest, if any, to (but not including) the redemption date, plus a specified “make-whole premium.” On or after September 30, 2023, we may redeem all or part of the Senior Notes at our option, at the redemption prices set forth in the Senior Notes, plus accrued and unpaid interest, if any, to (but not including) the redemption date. At any time prior to September 30, 2023, we could have redeemed up to 35% of the original aggregate principal amount of the Senior Notes with the net cash proceeds of certain equity offerings at a redemption price equal to 104.750% of the principal amount of the Senior Notes, together with accrued and unpaid interest, if any, to (but not including) the redemption date. If we undergo a change of control, we may be required to make an offer to holders of the Senior Notes to repurchase all of the Senior Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe effective tax rate was approximately (32)% and 45% for the nine months ended September 29, 2023 and September 30, 2022, respectively. The effective tax rate for the nine months ended September 29, 2023 as compared to the U.S. statutory rate of 21%, was primarily impacted by the non-deductible portion of a legal settlement on a legacy matter and the non-deductible charge associated with the cash settlement method election and Convertible Notes repurchase discussed in Note 18. The implications of these non-deductible items were partially offset by the release of a previously reserved position based on developments associated with the ongoing IRS examination and appeals process for certain years. The effective tax rate for the nine months ended September 30, 2022 was primarily impacted by the non-deductibility of losses incurred with respect to the settlement of outstanding matters related to the Ichthys LNG project to which KBR is a JV partner. The valuation allowance for deferred tax assets as of September 29, 2023 and December 31, 2022 was $215 million and $217 million, respectively. The remaining valuation allowance is primarily related to foreign tax credit carryforwards and foreign and state net operating loss carryforwards that, in the judgment of management, do not meet the more likely than not realization threshold. 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 utilization of the unreserved foreign tax credit carryforwards is based on our ability to generate income from foreign sources of approximately $367 million prior to their expiration. The utilization of other net deferred tax assets, excluding those associated with indefinite-lived intangible assets, is based on our ability to generate U.S. forecasted taxable income of approximately $781 million. Changes in our forecasted taxable income, in the appropriate character and source, as well as jurisdiction, could affect the ultimate realization of deferred tax assets. The provision for uncertain tax positions included in other liabilities and deferred income taxes on our condensed consolidated balance sheets as of September 29, 2023 and December 31, 2022 was $71 million and $92 million, respectively. The reduction in the provision for uncertain tax positions in the current year was primarily driven by the release of a previously reserved IRS audit position based on developments associated with the ongoing IRS examination and appeals process for certain years.

Commitments and Contingencies	Commitments and ContingenciesWe are a party to litigation and other proceedings that arise in the ordinary course of our business. These types of matters could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. We believe the probability is remote that the outcome of any individual matter, including the matters described below, will have a material adverse effect on the corporation as a whole, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings and cash flows in any particular reporting period. Among the factors that we consider in this assessment are the nature of existing legal proceedings and claims, the asserted or possible damages or loss contingency (if estimable), the progress of the case, existing law and precedent, the opinions or views of legal counsel and other advisers, our experience in similar cases and the experience of other companies, the facts available to us at the time of assessment and how we intend to respond to the proceeding or claim. Our assessment of these factors may change over time as individual proceedings or claims progress.Although we cannot predict the outcome of legal or other proceedings with certainty, when it is probable that a loss will be incurred and the amount is reasonably estimable, U.S. GAAP requires us to accrue an estimate of the probable loss or range of loss. In the event a loss is probable, but the probable loss is not reasonably estimable, we are required to make a statement that such an estimate cannot be made. We follow a thorough process in which we seek to estimate the reasonably possible loss or range of loss, and only if we are unable to make such an estimate do we conclude and disclose that an estimate cannot be made. Accordingly, unless otherwise indicated below in our discussion, a reasonably possible loss or range of loss associated with any individual contingency cannot be estimated. There have been no substantive developments or changes to existing claims.

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, which is responsible for the administration of the majority of our contracts. The scope of these audits includes, 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 any completed or ongoing government audits will have a material adverse impact on our results of operations, financial position or cash flows. The U.S. government also retains the right to pursue various remedies under any of these contracts which could result in challenges to expenditures, suspension of payments, fines and suspensions or debarment from future business with the U.S. government. The Company accrued for probable and reasonably estimable unallowable costs associated with open government matters related to our GS business in the amounts of $44 million as of September 29, 2023 and $61 million as of December 31, 2022, which are recorded in other liabilities on our condensed consolidated balance sheets. 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 closing out the LogCAP III contract since 2011, and we expect the contract closeout process to continue for at least another year. As a result of our work under LogCAP III, there are claims and disputes pending between us and the U.S. government that need to be resolved in order to close the contract. The contract 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 resolutions of these outstanding matters. 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 in the future. Investigations, Qui Tams and Litigation The following matters relate to ongoing litigation or federal investigations involving U.S. government contracts. Some of these matters involve allegations of violations of the FCA, which prohibits in general terms fraudulent billings to the U.S. government; these suits brought by private individuals are called "qui tams." In the event we prevail in defending these allegations, a majority of our defense costs will be billable under the LogCAP III contract. 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 for several claims under various LogCAP III subcontracts. After a series of arbitration proceedings and related litigation between KBR and the U.S. government, the panel heard the final claims and we received an award on July 27, 2022. FKTC filed a motion for correction of the award asking the tribunal to change its findings. The tribunal denied FKTC's motion in an order issued on October 20, 2022. KBR filed its response on February 2, 2023. On January 5, 2023, FKTC filed a motion to vacate the arbitral award in the Eastern District of Virginia Federal District Court. On March 22, 2023, both parties presented oral arguments in the Eastern District of Virginia Federal District Court. On May 12, 2023, the District Court issued its order denying FKTC’s motion to vacate the arbitration award and confirming the award. On June 12, 2023, the parties submitted their briefs in support of their calculations of the final award amount. KBR sought to confirm the net award of $16 million in KBR’s favor plus post judgment interest. FKTC sought to offset amounts awarded to KBR with amounts FKTC claimed it was owed based on unpaid principal and post award interest on the awards issued in its favor in the prior arbitration proceedings, totaling $70 million. KBR disagreed with FKTC’s interest claim and calculation. On September 22, 2023, the Court issued a decision finding the net amount due in favor of KBR from FKTC is $8 million. FKTC has appealed this ruling. In addition, in March 2022, FKTC filed a new civil action in Kuwait civil court against KBR seeking $100 million in damages. This action is duplicative of the claims decided in arbitration. In September 2022, we filed a motion to dismiss this action for lack of jurisdiction due to the arbitration agreement between KBR and FKTC. Based on our assessment of existing law and precedent, the opinions or views of legal counsel and the facts available to us, no amounts are accrued as of September 29, 2023. 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 government $628 million for unnecessary materials and equipment. In October 2014, the DOJ declined to intervene and the case was partially unsealed. KBR and the relators filed

Equity [Abstract]
Share Repurchases	Share Repurchases Authorized Share Repurchase Program On February 25, 2014, the Board of Directors authorized a plan to repurchase up to $350 million of our outstanding shares of common stock, which replaced and terminated the August 26, 2011 share repurchase program. On October 18, 2022, the Board of Directors authorized an increase to the total authorization level to $500 million. As of September 29, 2023, $326 million remains available for repurchase under this authorization. The authorization does not obligate the Company to acquire any particular number of shares of common stock 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 flows and the authorization does not have an expiration date. Withheld to Cover Program We have in place a "withhold 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.

Earnings Per Share [Abstract]
Income (loss) per Share	Income (loss) per Share Basic income (loss) per share is based upon the weighted average number of common shares outstanding during the period. Dilutive income (loss) per share includes additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued using the if-converted method for Convertible Debt and the treasury stock method for all other instruments. A summary of the basic and diluted net income (loss) per share calculations is as follows: Three Months Ended Nine Months Ended September 29, September 30, September 29, September 30, Shares in millions 2023 2022 2023 2022 Net income (loss) attributable to KBR: Net Income (loss) attributable to KBR $ (21) $ 74 $ (286) $ 97 Less earnings allocable to participating securities $ — $ — $ — $ (1) Basic net income (loss) attributable to KBR $ (21) $ 74 $ (286) $ 96 Reversal of Convertible Debt interest expense — 2 $ — 5 Diluted net income (loss) attributable to KBR $ (21) $ 76 $ (286) $ 101 Weighted average common shares outstanding: Basic weighted average common shares outstanding 135 139 136 139 Convertible Debt — 14 — 14 Warrants — 3 — 3 Diluted weighted average common shares outstanding 135 156 136 156 Net income (loss) attributable to KBR per share: Basic $(0.16) $0.53 $ (2.10) $0.69 Diluted $(0.16) $0.49 $ (2.10) $0.65 Due to our net loss position for both the three and nine months ended September 29, 2023, our basic net loss attributable to KBR per share and diluted net loss attributable to KBR per share are identical as the effect of all potential common shares is anti-dilutive and therefore excluded. We apply the if-converted method to our Convertible Debt when calculating diluted net income (loss) attributable to KBR per share until the date of election of cash as the settlement method. Under the if-converted method, the principal amount and any conversion spread of the Convertible Debt, to the extent dilutive, are assumed to be converted into common stock at the beginning of the period and net income (loss) attributable to KBR is adjusted to reverse the effect of any interest expense associated with the Convertible Debt. For the three months ended September 29, 2023, the diluted net income (loss) attributable to KBR per share calculation excluded the following weighted-average potential common shares because their inclusion would have been anti-dilutive: 9.9 million related to the Warrant Transactions and 1.3 million related to our stock options and restricted stock awards. For the nine months ended September 29, 2023, the diluted net income (loss) attributable to KBR per share calculation excluded the following weighted-average potential common shares because their inclusion would have been anti-dilutive: 5.3 million related to the Convertible Debt, 12.1 million related to the Warrant Transactions and 1.4 million related to our stock options and restricted stock awards. For the three and nine months ended September 30, 2022, the diluted net income (loss) attributable to KBR per share calculation excluded the following weighted-average potential common shares because their inclusion would have been anti-dilutive: 11.2 million related to the Warrant Transactions and 0.5 million related to our stock options and restricted stock awards.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments and Risk Management	Fair Value of Financial Instruments and Risk Management Fair value measurements. The fair value of an asset or liability is the price that would be received to sell an asset or transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value and defines three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, inputs other than quoted prices that are observable for the asset or liability or inputs derived from observable market data. Level 3 inputs are unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. The carrying amount of cash and cash equivalents, accounts receivable and accounts payable, as reflected in the condensed consolidated balance sheets, approximates fair value due to the short-term maturities of these financial instruments. The carrying values and estimated fair values of our financial instruments that are not required to be recorded at fair value in our condensed consolidated balance sheets are provided in the following table. The fair value of our note hedge derivative asset and embedded derivative liability are included in other current assets and other current liabilities on our condensed consolidated balance sheets at September 29, 2023. 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.

See Note 9 "Debt and Other Credit Facilities" for the debt issuance costs of these instruments and further discussion of our term loans, Convertibles Notes, Senior Notes and Revolver. The increase in carrying value of the Convertible Notes and conversion option is due to the bifurcation of the Convertible Notes' conversion option in April 2023. See Note 18 "Cash Election and Repurchase of Convertible Notes" for additional information regarding this bifurcation. The following disclosures for foreign currency risk and interest rate risk includes the fair value hierarchy levels for our assets and liabilities that are measured at fair value on a recurring basis. 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 29, 2023, the gross notional value of our foreign currency exchange forwards and option contracts used to hedge balance sheet exposures was $45 million, all of which had durations of 16 days or less. We also had approximately $3 million (gross notional value) of cash flow hedges which had durations of 9 months or less. The cash flow hedges are related to the British Pound. The fair value of our balance sheet hedges and cash flow hedges are included in other current assets and other current liabilities on our condensed consolidated balance sheets at September 29, 2023, and December 31, 2022. 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 expense on our condensed consolidated statements of operations.

We use interest rate swaps to reduce interest rate risk and to manage net interest expense by converting a portion of our variable rate debt under our Senior Credit Facility into fixed-rate debt. During the nine months ended September 29, 2023, we amended all of our existing interest rate swap agreements to term SOFR effective March 2023. We elected to apply the optional expedient in ASC 848 in connection with transitioning our interest rate swaps from LIBOR to term SOFR that allowed the amended swaps to be considered as a continuation of the existing hedges. As a result, the reference rate transition did not have an impact on our hedge accounting or a material impact to our condensed consolidated financial statements. Additionally, in March 2023, we entered into additional USD and GBP denominated interest rate swap agreements. Our portfolio of interest rate swaps consists of the following: Dollars in millions Notional Amount at September 29, 2023 Pay Fixed Rate (Weighted Average) Receive Variable Rate Settlement and Termination March 2020 Interest Rate Swaps $ 400 0.89 % Term SOFR Monthly through January 2027 September 2022 Interest Rate Swaps (a) $ 250 3.43 % Term SOFR Monthly through January 2027 March 2023 Interest Rate Swaps $ 205 3.61 % Term SOFR Monthly through January 2027 March 2023 Amortizing Interest Rate Swaps £ 118 3.81 % Term SONIA Monthly through November 2026 (a) Effective November 2023, the notional value will increase to $350 million through maturity in January 2027. Our interest rate swaps are reported at fair value using Level 2 inputs. The fair value of the interest rate swaps at September 29, 2023 was a $65 million asset, of which $29 million is included in other current assets and $36 million is included in other assets. The unrealized net gain on these interest rate swaps was $65 million and is included in AOCL as of September 29, 2023. The fair value of the interest rate swaps at December 31, 2022, was a $48 million net asset, of which $19 million is included in other current assets and $29 million is included in other assets. The unrealized net gains on these interest rate swaps was $48 million and is included in AOCL as of December 31, 2022. Sales of Receivables. From time to time, we sell certain receivables to unrelated third-party financial institutions under various accounts receivable monetization programs. One such program is with MUFG Bank, Ltd. (“MUFG”) under a Master Accounts Receivable Purchase Agreement (the “RPA”), which provides the sale to MUFG of certain of our designated eligible receivables, with a significant portion of such receivables being owed by the U.S. government. During the nine months ended September 29, 2023, the Company has derecognized $2,250 million of accounts receivables from the balance sheet under these agreements, of which certain receivables totaling $2,208 million were sold under the MUFG RPA. The fair value of the sold receivables approximated their book value due to their short-term nature. The fees incurred are presented in other non-operating expense on the condensed consolidated statements of operations. Activity for third-party financial institutions consisted of the following: Nine Months Ended Dollars in millions September 29, 2023 September 30, 2022 Beginning balance $ 134 481 Sale of receivables 2,250 2,236 Settlement of receivables (2,243) (2,612) Cash collected, not yet remitted — (4) Outstanding balances sold to financial institutions $ 141 $ 101 Other Investments. Other investments include investments in equity securities of privately held companies without readily determinable fair values and are included in other assets on our condensed consolidated balance sheets. These investments are accounted for under the measurement alternative, provided that KBR does not have the ability to exercise significant influence or control over the investees.

Recent Accounting Pronouncement

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements New accounting pronouncements requiring implementation in future periods are discussed below. In 2017, the United Kingdom's Financial Conduct Authority announced that after 2021 it would no longer compel banks to submit the rates required to calculate the London Interbank Offered Rate (LIBOR), which have been widely used as reference rates for various securities and financial contracts, including loans, debts and derivatives. This announcement indicates that the continuation of LIBOR on the current basis is not guaranteed after 2021. Subsequently in March 2021, the Financial Conduct Authority announced some USD LIBOR tenors (overnight, 1-month, 3-month, 6-month and 12-month) will continue to be published until June 30, 2023. Regulators in the U.S. and other jurisdictions have been working to replace these rates with alternative reference interest rates that are supported by transactions in liquid and observable markets, such as the SOFR for USD LIBOR. All of our debt instruments that referenced LIBOR base rates have been amended to utilize alternative reference rates. We have adhered to the ISDA 2020 IBOR Fallbacks Protocol, which will govern our derivatives upon the final termination of USD LIBOR index benchmark. ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , as amended, helps limit the accounting impact from contract modifications, including hedging relationships, due to the transition from LIBOR to alternative reference rates that are completed by December 31, 2022. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , which extends the period of time entities can utilize the reference rate reform guidance under ASU 2020-04 from December 31, 2022 to December 31, 2024. We elected to apply the optional expedient in ASC 848 in connection with transitioning our interest rate swaps from LIBOR to term SOFR that allowed the amended swaps to be considered as a continuation of the existing hedges. As a result, the reference rate transition did not have an impact on our hedge accounting or a material impact to our condensed consolidated financial statements. Additionally, the transition of our Senior Credit Facility from LIBOR to an alternate reference rate, did not have a significant impact to our financial results, financial position or cash flows as we elected to apply the optional expedients. In March 2023, the FASB issued 2023-01, Leases (Topic 842) - Common Control Arrangements, which requires leasehold improvements associated with common control leases to be amortized over the useful life of the leasehold improvements to the common control group as long as the lessee controls the underlying asset through a lease. The amendments are effective for all entities for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements. We are currently evaluating the future impact of this standard.

Debt Disclosure [Abstract]
Cash Election and Repurchase of Convertible Notes	Cash Election and Repurchase of Convertible Notes Cash Election for Convertible Notes. Upon issuance of the Convertible Notes, we had the right to elect to settle the Convertible Notes in cash, shares of our common stock or a combination of cash and shares of our common stock. As a result, our conversion option qualified for the equity scope exception under ASC 815 Derivatives and Hedging (“ASC 815”) that does not require the conversion option to be accounted for as a separate instrument. The Note Hedge Transactions and Warrant Transactions also qualified for the equity scope exception under ASC 815. In April 2023, we elected cash as the settlement method to settle the principal and any excess value upon early conversion or maturity of the Convertible Notes and Note Hedge. Upon that election, both instruments no longer qualified for the equity scope exception under ASC 815. The conversion option of the Convertible Notes was deemed to be embedded, which required bifurcation from the host contract, and the Note Hedge was reclassified to a freestanding derivative instrument. Upon bifurcation of the Convertible Notes' conversion option, we recorded an embedded derivative liability at fair value of $454 million, a debt discount of $350 million reducing the carrying value of our Convertible Notes to zero, and a $104 million loss. Upon reclassification of the Note Hedge, we recorded a derivative asset of $454 million at fair value, with an offset of $454 million to PIC. Any changes related to the fair value of the derivative asset will be directly offset by the change in fair value of the embedded derivative liability. The fair value of the derivative asset and embedded derivative liability at September 29, 2023 was $335 million. We have recorded $114 million and $242 million of accretion during the three and nine months ended September 29, 2023, respectively, and accelerated the accretion of $69 million as a loss on debt extinguishment associated with the repurchase of $100 million of Convertible Senior Notes in the second quarter of 2023. At September 29, 2023, the remaining debt discount of $40 million will be accreted over the remaining term of the Convertible Notes using the straight-line method if held through the maturity date of November 1, 2023. Convertible Senior Notes Repurchase and Unwind Agreements. On June 1, 2023, we entered into privately-negotiated transactions to repurchase $100 million in principal amount of the outstanding Convertible Notes (the “Convertible Notes repurchase”), using funds borrowed under our Revolver to pay the purchase price. Concurrent with the Convertible Notes repurchase, we entered into agreements with the option counterparties to terminate the corresponding portions of the Note Hedge Transactions and Warrant Transactions (collectively, the "Unwind Agreements"). We paid $250 million related to the Convertible Notes repurchase and received a net amount of $49 million related to the Unwind Agreements. The portion of warrants settled in cash during the second quarter of 2023 no longer qualified for the equity scope exception under ASC 815 upon execution of the Unwind Agreements on June 1, 2023. This resulted in the recognition of a derivative liability of $89 million, with an offset of $89 million to PIC. Upon settlement of the Unwind Agreements, during the second quarter of 2023 we recognized $12 million in loss due to the change in fair value of the derivative liability between the initial recognition date and settlement date. This loss was recorded within "Charges associated with Convertible Notes" on our condensed consolidated statement of operations. The Convertible Notes repurchase was accounted for as a debt extinguishment under ASC 470 Debt (“ASC 470”). ASC 470 requires the settlement consideration of $250 million to be allocated to both the carrying value of the debt instrument and the embedded derivative liability related to the conversion option. We recognized a loss on extinguishment of debt of $70 million due to the difference between the consideration paid of $250 million and the carrying value of the conversion option’s derivative liability and Convertible Notes, net of debt discount on the date of repurchase. See below for summary of items related to the cash election and repurchase of Convertible Notes and Note Hedge Transactions on our Condensed Consolidated Statement of Operations for the three and nine months ended September 29, 2023.

We account for investments over which we have significant influence, but not a controlling financial interest, using the equity method of accounting. See Note 7 "Equity Method Investments and Variable Interest Entities" to our condensed consolidated financial statements for further discussion of our equity investments and VIEs. All material intercompany balances and transactions are eliminated in consolidation.
Basis of Presentation	Basis of Presentation On December 13, 2022, the Board of Directors approved a change in the fiscal year end from a calendar year ending on December 31 to a 52 – 53 week year ending on the Friday closest to December 31, effective as of the commencement of the Company's fiscal year on January 1, 2023. In a 52 week fiscal year, each of the Company’s quarterly periods will comprise 13 weeks. The additional week in a 53 week fiscal year is added to the fourth quarter, making such quarter consist of 14 weeks. The Company’s first 53 week fiscal year will occur in fiscal year 2024. The Company made the fiscal year change on a prospective basis and will not adjust operating results for prior periods. The change will impact the prior year comparability of each of the fiscal quarters and the annual period for the year ending December 31, 2023, however, the impact will not be material. The Company believes this change will improve comparability between periods by eliminating the year-over-year variability in calendar month productive days and provide a more consistent reporting cadence for operational leaders to aid in strategic decision making. Due to this change in fiscal year, our third fiscal quarter ended on September 29 in 2023 as compared to September 30 in 2022. The three months ended September 29, 2023 and September 30, 2022 contained 90 days and 91 days, respectively. The nine months ended September 29, 2023 and September 30, 2022 contained 272 days and 273 days, respectively.
Impact of Adoption of New Accounting Standards and Recent Accounting Pronouncements	Impact of Adoption of New Accounting Standards Effective January 1, 2023, we adopted ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires entities to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . The update will generally result in an entity recognizing contract assets and contract liabilities at amounts consistent with those recorded by the acquiree immediately before the acquisition date rather than at fair value. The adoption of this standard did not have an impact on our condensed consolidated financial statements. However, the ultimate impact is dependent upon the size and frequency of future acquisitions. New accounting pronouncements requiring implementation in future periods are discussed below. In 2017, the United Kingdom's Financial Conduct Authority announced that after 2021 it would no longer compel banks to submit the rates required to calculate the London Interbank Offered Rate (LIBOR), which have been widely used as reference rates for various securities and financial contracts, including loans, debts and derivatives. This announcement indicates that the continuation of LIBOR on the current basis is not guaranteed after 2021. Subsequently in March 2021, the Financial Conduct Authority announced some USD LIBOR tenors (overnight, 1-month, 3-month, 6-month and 12-month) will continue to be published until June 30, 2023. Regulators in the U.S. and other jurisdictions have been working to replace these rates with alternative reference interest rates that are supported by transactions in liquid and observable markets, such as the SOFR for USD LIBOR. All of our debt instruments that referenced LIBOR base rates have been amended to utilize alternative reference rates. We have adhered to the ISDA 2020 IBOR Fallbacks Protocol, which will govern our derivatives upon the final termination of USD LIBOR index benchmark. ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , as amended, helps limit the accounting impact from contract modifications, including hedging relationships, due to the transition from LIBOR to alternative reference rates that are completed by December 31, 2022. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , which extends the period of time entities can utilize the reference rate reform guidance under ASU 2020-04 from December 31, 2022 to December 31, 2024. We elected to apply the optional expedient in ASC 848 in connection with transitioning our interest rate swaps from LIBOR to term SOFR that allowed the amended swaps to be considered as a continuation of the existing hedges. As a result, the reference rate transition did not have an impact on our hedge accounting or a material impact to our condensed consolidated financial statements. Additionally, the transition of our Senior Credit Facility from LIBOR to an alternate reference rate, did not have a significant impact to our financial results, financial position or cash flows as we elected to apply the optional expedients. In March 2023, the FASB issued 2023-01, Leases (Topic 842) - Common Control Arrangements, which requires leasehold improvements associated with common control leases to be amortized over the useful life of the leasehold improvements to the common control group as long as the lessee controls the underlying asset through a lease. The amendments are effective for all entities for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements. We are currently evaluating the future impact of this standard.

Additionally, during the third quarter of 2022, we recorded a charge against a joint venture acquired from a historical GS acquisition of $10 million based on our funding obligations of projected losses. In the fourth quarter of 2022, we divested this joint venture and recorded an incremental loss on sale of $3 million. The remaining equity in earnings (losses) of unconsolidated affiliates in 2023 and 2022 is related to normal activities within our other joint ventures. (b) In the normal course of business, our joint ventures will declare a distribution in the current quarter that is not paid until the subsequent quarter.

(c) During the nine months ended September 29, 2023, we received a return of investment from JKC of approximately $61 million related to the second payment received from the Subcontractor Settlement Agreement. For the year ended December 31, 2022, we received a return of investment from JKC of approximately $190 million related to the first payment from the Subcontractor Settlement Agreement and from BRIS of $10 million as our cumulative distributions from inception of the joint venture exceeded our cumulative earnings. (d) During the first quarter of 2022, we sold two of our four U.K. Road investments. The carrying value of our investment was $22 million. We received $18 million in cash proceeds and the purchaser agreed to assume the $4 million of consortium relief. In the second quarter of 2022, we sold an additional U.K. Road investment with a carrying value of $19 million and recorded a gain of approximately $16 million upon receipt of $35 million in cash proceeds, in addition to receipt of $2 million of deferred consideration from the first quarter 2022 sales. (e) During the nine months ended September 29, 2023, Other included a net liability position of $52 million related to our investment in JKC.
