Note 1. 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 2023 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 March 29, 2024, the results of our operations for the three months ended March 29, 2024 and March 31, 2023, respectively, and our cash flows for the three months ended March 29, 2024 and March 31, 2023, respectively. Our significant accounting policies are detailed in "Note 1. Significant Accounting Policies" of our 2023 Annual Report on Form 10-K. The Company's fiscal year ends on the Friday closest to December 31. The three months ended March 29, 2024 and March 31, 2023 contained 91 days and 90 days, respectively.

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 6 "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.

Note 2. Business Segment Information

We provide a wide range of professional services and the management of our business is heavily focused on major projects or programs within each of our reportable segments. At any given time, government programs and joint ventures represent a substantial part of our operations.

Operations by Reportable Segment

Note 3. Revenue

Disaggregated Revenue

We disaggregate our revenue from customers by business unit, 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.

Revenue by business unit and reportable segment was as follows:

Government Solutions revenue earned from key U.S. government customers includes U.S. DoD agencies and NASA, and is reported as Science & Space, Defense & Intel and Readiness & Sustainment. Government Solutions revenue earned from non-U.S. government customers primarily includes the U.K. MoD and the Australian Defence Force and is reported as International.

Revenue by geographic destination was as follows:

Many of our contracts contain cost reimbursable, time-and-materials and fixed price components. We define contract type based on the component that represents the majority of the contract. Revenue by contract type was as follows:

Performance Obligations and Contract Liabilities

Changes in estimates are recognized on a cumulative catch-up basis in the current period associated with performance obligations satisfied in a prior period due to the release of a constrained milestone, modification in contract price or scope or a change in the likelihood of a contingency being resolved.

On March 29, 2024, we had $12.9 billion of transaction price allocated to remaining performance obligations. We expect to recognize approximately 38% of our remaining performance obligations as revenue withinone year,36% in years two through five and 26% 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 March 29, 2024.

We recognized revenue of $174 million and $126 million for the three months ended March 29, 2024 and March 31, 2023, respectively, which was previously included in the contract liability balance at the beginning of each period.

Accounts Receivable

Note 4. Cash and Cash Equivalents

We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash 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, new acquisitions and joint ventures, general cash needs or distribution to us without approval of the board of directors of the respective entities. The cash and cash equivalents held in consolidated joint ventures and the Aspire project are expected to be used for their respective project costs and distributions of earnings.

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

(a)Includes deposits held by non-U.S. entities with operating accounts that constitute offshore cash for tax purposes.

(b)Includes U.S. dollar and foreign currency deposits held in U.S. entities with 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.

(d)Includes short-term investments held by Aspire Defence subcontracting entities for $85 million and $83 million as of March 29, 2024 and December 29, 2023, respectively.

Note 5. Unapproved Change Orders and Claims Against Clients and Estimated Recoveries of Claims Against Suppliers and Subcontractors

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

The balance as of March 29, 2024 primarily relates to projects in our Government Solutions segment.

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.

Note 6. 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:

(a)The equity in earnings of unconsolidated affiliates in 2024 and 2023 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)For the three months ended March 29, 2024, we received a return of investment from JKC of approximately $29 million related to our proportionate share of a tax refund. During the year ended December 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.

(d)During the three months ended March 29, 2024, Other included the reclassification of the net liability position of $38 million related to joint ventures within our STS business segment. During the year ended December 29, 2023, Other included the reclassification of the net liability position of $47 million related to a joint venture within our STS business segment.

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 three months ended March 29, 2024 and March 31, 2023, our revenues included $173 million and $124 million, respectively, 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 March 29, 2024, and December 29, 2023 are as follows:

Note 7. Retirement Benefits

We havetwo frozen defined benefit pension plans in the U.S., one frozen andone active plan in the U.K. andone frozen plan in Germany. The components of net periodic pension benefit related to the frozen U.K. pension for the three months ended March 29, 2024 and March 31, 2023, respectively, were as follows:

For the three months ended March 29, 2024, we have contributed approximately $7 million of the $39 million we expect to contribute to our U.K. pension plan in 2024.

Note 8. Debt and Other Credit Facilities

Our outstanding debt consisted of the following at the dates indicated:

Senior Credit Facility

Our existing Credit Agreement, dated as of April 25, 2018, as amended ("Credit Agreement"), consists 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" and together with the Revolver and Term Loan A, the "Senior Credit Facility").

We entered into Amendment No.11 to our Credit Agreement on January 19, 2024. This amendment provides for an incremental Term Loan B facility in an aggregate principal amount of $1 billion and extends the Term Loan B maturity date to January 2031. We borrowed the full $1 billion principal amount available under this loan. We received $24 million in cash proceeds from this borrowing to pay accrued interest and financing fees, $501 million was applied to the outstanding principal under the Term Loan B facility and the remaining $475 million was applied to the outstanding principal under the Revolver. In addition, Amendment No.11 reduced the interest rate margin applicable to Term Loan B.

We entered into Amendment No.12 to our Credit Agreement on February 7, 2024. This amendment consolidated the USD denominated Term A-1, Term A-2 and Term A-4 loan facilities under our Credit Agreement into the amended USD denominated Term A-1 loan facility and continued the GBP denominated Term A-3 loan facility outstanding at December 29, 2023. In 2024, $76 million in cash was paid on the outstanding Term Loan A principal and accrued interest and $20 million was applied to the Term Loan A principal through a borrowing on our Revolver. Additionally, this amendment extended the maturity date of the $1 billion Revolver, amended Term A-1 loan facility and Term A-3 loan facility to February 2029.

We had cash borrowings of $93 million on our Revolver that occurred during the three months ended March 29, 2024. The interest rates with respect to the Revolver, Term Loan A and Term Loan B are based on, at our option, the applicable adjusted reference rate plus an additional margin or base rate plus additional margin. 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 Revolver and Term Loan A are based on our consolidated net leverage ratio as follows:

(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.

The details of the applicable margins under the amended Term Loan B are based on our consolidated net leverage ratio as follows:

(a)The reference rate for the Term Loan B is SOFR.

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 April 3, 2026. 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 February 2029 and Term Loan B matures in January 2031.

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 4.25 to 1 in 2023, reducing to 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 March 29, 2024, we were in compliance with our financial covenants related to our debt agreements.

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.

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. 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.

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 in the ordinary course of business as credit support for contractual performance guarantees, advanced payments received from customers and future funding commitments. As of March 29, 2024, we had $1 billion in a committed line of credit on the Revolver under our Senior Credit Facility and $395 million of bilateral and uncommitted lines of credit. As of March 29, 2024, with respect to our Revolver, we had $143 million of outstanding borrowings. We also have $14 million of outstanding letters of credit on our Senior Credit Facility. With respect to our $395 million of bilateral and uncommitted lines of credit, we utilized $291 million for letters of credit as of March 29, 2024. The total remaining capacity of these committed and uncommitted lines of credit was approximately $947 million, of which up to approximately $791 million can be used toward issuing letters of credit. Of the letters of credit outstanding under the Senior Credit Facility, none have expiry dates beyond the maturity date of the Senior Credit Facility. Of the total letters of credit outstanding under our bilateral facilities, $84 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.

Note 9. Income Taxes

The effective tax rate was approximately 27% and 26% for the three months ended March 29, 2024 and March 31, 2023, respectively. The effective tax rate for the three months ended March 29, 2024 and March 31, 2023 as compared to the U.S. statutory rate of 21%, was primarily affected by the rate differential on our foreign earnings and the impact of state and local taxes in the U.S.

The valuation allowance for deferred tax assets as of March 29, 2024 and December 29, 2023 was $148 million. 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 $210 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 $957 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 March 29, 2024 and December 29, 2023 was $73 million and $74 million, respectively.

Note 10. Commitments and Contingencies

We 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.

Note 11. U.S. Government Matters

We provide services to various U.S. governmental agencies, including the U.S. DoD, NASA and the Department of State. 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.

We accrued for probable and reasonably estimable unallowable costs associated with open government matters related to our GS business in the amounts of $45 million as of March 29, 2024 and $45 million as of December 29, 2023, 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 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 administratively closing the individual task orders issued under the contract. We continue to work with the U.S. government to resolve the issues to close the remaining task orders, which includes ongoing litigation of third-party vendor disputes. 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.

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. On January 5, 2023, FKTC filed a motion to vacate the arbitral award in the Eastern District of Virginia Federal District Court. KBR filed its response on February 2, 2023. On March 22, 2023, both parties presented oral arguments. 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 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. On December 7, 2023, the Kuwait Court of Cassation issued a ruling ordering KBR to pay an immaterial provisional damage award and requiring FKTC to refile its case in the Court of First Instance for adjudication. Based on our assessment of existing law and precedent, the opinions or views of legal counsel and the facts available to us, no amounts were accrued as of March 29, 2024.

Changes in AOCL, net of tax, by component

Reclassifications out of AOCL, net of tax, by component

(a)This item is included in the computation of net periodic pension cost. See Note 7 "Retirement Benefits" to our condensed consolidated financial statements for further discussion.

Note 13. Share Repurchases

Authorized Share Repurchase Program

On February 25, 2014, the Board of Directors authorized a plan to repurchase our outstanding shares of common stock, which replaced and terminated the August 26, 2011 share repurchase program. On February 19, 2024, the Board of Directors authorized $174 million of additional share repurchases to be added to the prior authorizations, which returned the total amount authorized and available for repurchase under the share repurchase program to $500 million. As of March 29, 2024, $450 million remains available for repurchase under this authorization. The authorization does not obligate us 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 our 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.

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

Note 14. 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 if-converted method for Convertible Debt and the treasury stock method for all other instruments.

A summary of the basic and diluted net income per share calculations is as follows:

The Convertible Debt and Warrants outstanding in 2023 had dilutive effects to our basic net income attributable to KBR per share. For the three months ended March 29, 2024, the diluted net income attributable to KBR per share calculation excluded the following weighted-average potential common shares because their inclusion would have been anti-dilutive:0.3 million related to our stock options and restricted stock awards. For the three months ended March 31, 2023, the diluted net income attributable to KBR per share calculation excluded the following weighted-average potential common shares because their inclusion would have been anti-dilutive:10.5 million related to the Warrant Transactions and 0.4 million related to our stock options and restricted stock awards.

Note 15. 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. We utilize 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 carrying value of the debt instruments listed above exclude debt issuance costs for the respective instrument. See Note 8 "Debt and Other Credit Facilities" for the debt issuance costs of our debt instruments and further discussion of our term loans, Senior Notes and Revolver. We paid the outstanding warrant derivative liability at December 29, 2023 of $33 million in 2024.

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 March 29, 2024, the gross notional value of our foreign currency exchange forwards and option contracts used to hedge balance sheet exposures was $39 million, all of which had durations of 15 days or less. We also had approximately $1 million (gross notional value) of cash flow hedges which had durations of 3 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 assets on our condensed consolidated balance sheets at March 29, 2024, and December 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.

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.

Interest rate risk. 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. Our portfolio of interest rate swaps consists of the following:

Our interest rate swaps are reported at fair value using Level 2 inputs. The fair value of the interest rate swaps at March 29, 2024 was a $48 million asset, of which $25 million is included in other current assets and $23 million is included in other assets. The unrealized net gain on these interest rate swaps was $48 million and is included in AOCL as of March 29, 2024. The fair value of the interest rate swaps at December 29, 2023, was a $36 million net asset, of which $24 million is included in other current assets, $18 million is included in other assets and $6 million is included in other liabilities. The unrealized net gains on these interest rate swaps was $36 million and is included in AOCL as of December 29, 2023.

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 three months ended March 29, 2024, we derecognized $755 million of accounts receivables from the balance sheet under these agreements, of which certain receivables totaling $746 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:

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.

Note 16. Recent Accounting Pronouncements

New accounting pronouncements requiring implementation in future periods are discussed below.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss, and the title and position of the entity’s CODM. The amendments in this update also expand the interim segment disclosure requirements. ASU 2023-07 will be effective for our 2024 fiscal year and for interim periods starting in our first quarter of fiscal year 2025. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, the ASU requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition.

In March 2024, the U.S. Securities and Exchange Commission ("SEC") adopted the final rule under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors. This rule would require registrants to disclose certain climate-related information in registration statements and annual reports. In April 2024, the SEC issued a stay of the final rules pending a judicial review of the validity of the rules by the Eighth Circuit Court of Appeals. We are currently evaluating the final rule to determine its impact on our disclosures.
