Description of Business
Jacobs Solutions Inc. ("Jacobs" or "the Company") is a leading global professional services company that designs and deploys technology-centric solutions to solve many of the world’s most complex challenges. The services Jacobs provides to end markets fall into the following two operating segments: Infrastructure & Advanced Facilities and our investment in PA Consulting Group Limited ("PA Consulting"). See Note 20- Segment Information.
From advisory and consulting, feasibility, planning, design, program and lifecycle management, Jacobs provides end-to-end services in advanced manufacturing, cities & places, energy, environmental, life sciences, transportation and water. Jacobs provides its services through offices and subsidiaries located primarily in North America, Europe, the Middle East, India, Australia, New Zealand and Asia. Jacobs provides its services under cost-reimbursable and fixed-price contracts, with fixed-price contracts comprised mainly of professional services arrangements and in some limited cases, construction. The percentage of revenues realized from each of these types of contracts for the fiscal years ended September 27, 2024, September 29, 2023 and September 30, 2022 was as follows:

Basis of Presentation, Definition of Fiscal Year, and Other Matters
The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and include the accounts of Jacobs Solutions Inc. and its subsidiaries and affiliates which it controls. On August 29, 2022, Jacobs Engineering Group Inc. (JEGI), the predecessor to Jacobs Solutions Inc., implemented a holding company structure, which resulted in Jacobs Solutions Inc. becoming the parent company of, and successor issuer to, JEGI (the "Holding Company Reorganization"). Prior to the implementation date, the Consolidated Financial Statements include the accounts of JEGI and its subsidiaries and affiliates which it controlled. All intercompany accounts and transactions have been eliminated in consolidation.
The Company’s fiscal year ends on the Friday closest to September 30 (determined on the basis of the number of workdays) and, accordingly, an additional week of activity is added every five-to-six years. Fiscal 2020 included an extra week of activity.
On September 27, 2024, Jacobs Solutions Inc. ("Jacobs") completed the previously announced Reverse Morris Trust transaction pursuant to which (i) Jacobs first transferred its Critical Mission Solutions business (“CMS”) and portions of its Divergent Solutions (“DVS”) business (referred to herein as the Cyber & Intelligence business (“C&I”) and together with CMS referred to as the “SpinCo Business”), to Amazon Holdco Inc., a Delaware corporation, that was subsequently renamed Amentum Holdings, Inc. (“SpinCo”) (the “Separation”), (ii) Jacobs then effectuated a spin-off of SpinCo by distributing 124,084,108 shares of SpinCo common stock, par value $0.01 per share (the “SpinCo Common Stock”) by way of a pro rata distribution to its shareholders such that each holder of shares of Jacobs common stock, par value $1.00 per share, (the “Jacobs Common Stock”) was entitled to receive one share of SpinCo Common Stock for each share of Jacobs common stock held as of the record date, September 23, 2024 (the “Distribution”), and (iii) finally, Amentum Parent Holdings LLC merged with and into SpinCo, with SpinCo surviving the merger (the “Merger” and together with the Separation and the Distribution, the “Separation Transaction”).
As a result of the Separation, substantially all SpinCo Business-related assets and liabilities have been separated and distributed (the "Disposal Group"). The Company determined that the Disposal Group should be reported as discontinued operations in accordance with ASC 205-20, Discontinued Operations because their disposal represents a strategic shift that had a major effect on the Company's operations and financial results. As such, the financial results of the SpinCo Business are reflected in the Company's Consolidated Statements of Earnings as well as relevant disclosures as discontinued operations for all periods presented.

Revenue Accounting for Contracts
Engineering, Procurement & Construction Contracts, Service Contracts and Software Contracts
The Company recognizes engineering, procurement, and construction contract revenue over time, as performance obligations are satisfied, due to the continuous transfer of control to the customer in accordance with ASC Topic 606, Revenue from Contracts with Customers. Contracts which include engineering, procurement and construction services are generally accounted for as a single deliverable (a single performance obligation) and are no longer segmented between types of services. In some instances, the Company’s services associated with a construction activity are limited to specific tasks such as customer support, consulting or supervisory services. In these instances, the services are typically identified as separate performance obligations.
The Company recognizes revenue using the percentage-of-completion method, based primarily on contract costs incurred to date compared to total estimated contract costs. The percentage-of-completion method (an input method) is the most representative depiction of the Company’s performance because it directly measures the value of the services transferred to the customer. Subcontractor materials, labor and equipment and, in certain cases, customer-furnished materials and labor and equipment are included in revenue and cost of revenue when management believes that the company is acting as a principal rather than as an agent (e.g., the company integrates the materials, labor and equipment into the deliverables promised to the customer or is otherwise primarily responsible for fulfillment and acceptability of the materials, labor and/or equipment). The Company recognizes revenue, but not profit, on certain uninstalled materials that are not specifically produced, fabricated, or constructed for a project. Changes to total estimated contract cost or losses, if any, are recognized in the period in which they are determined as assessed at the contract level. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. Project mobilization costs are generally charged to project costs as incurred when they are an integrated part of the performance obligation being transferred to the client. Under the typical payment terms of our engineering, procurement and construction contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms at periodic intervals (e.g., biweekly or monthly) and customer payments are typically due within 30 to 60 days of billing, depending on the contract.
For service contracts, the Company recognizes revenue over time using the cost-to-cost percentage-of-completion method. Service contracts that include multiple performance obligations are segmented between types of services. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using an estimate of the stand-alone selling price of each distinct service in the contract. In some instances where the Company is standing ready to provide services, the Company recognizes revenue ratably over the service period. Under the typical payment terms of our service contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, and customer payments are typically due within 30 to 60 days of billing, depending on the contract.
Revenue for certain contracts related to the sale of software licenses is recognized at a point in time, typically at the time of delivery, in accordance with ASC 606. The software license sale will be treated as a performance obligation separate and distinct from any related service and maintenance.
Direct costs of contracts include all costs incurred in connection with and directly for the benefit of client contracts, including depreciation and amortization relating to assets used in providing the services required by the related projects. The level of direct costs of contracts may fluctuate between reporting periods due to a variety of factors, including the amount of pass-through costs we incur during a period. On those projects where we are acting as principal for subcontract labor or third-party materials and equipment, we reflect the amounts of such items in both revenues and costs (and we refer to such costs as “pass-through costs”).
    Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable, and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above have been satisfied.
Variable Consideration
The nature of the Company’s contracts gives rise to several types of variable consideration, including claims and unpriced change orders; awards and incentive fees; and liquidated damages and penalties. The Company recognizes revenue for variable consideration when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company estimates the amount of revenue to be recognized on variable consideration using the expected value (i.e., the sum of a probability-weighted amount) or the most likely amount method, whichever is expected to better predict the amount. Factors considered in determining whether revenue associated with claims (including change orders in dispute and unapproved change orders in regard to both scope and price) should be recognized include the following: (a) the contract or other evidence provides a legal basis for the claim, (b) additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in the company’s performance, (c) claim-related costs are identifiable and considered reasonable in view of the work performed, and (d) evidence supporting the claim is objective and verifiable. If the requirements for recognizing revenue for claims or unapproved change orders are met, revenue is recorded only when the costs associated with the claims or unapproved change orders have been incurred and only up to the amount of consideration that is probable of not being reversed.
The Company generally provides limited warranties for work performed under its engineering and construction contracts. The warranty periods typically extend for a limited duration following substantial completion of the Company’s work on the project. Historically, warranty claims have not resulted in material costs incurred for which the Company was not compensated for by the customer.
See Note 3- Revenue Accounting for Contracts for further discussion.
Joint Ventures and VIEs
As is common to the industry, we execute certain contracts jointly with third parties through various forms of joint ventures. Although the joint ventures own and hold the contracts with the clients, the services required by the contracts are typically performed by us and our joint venture partners, or by other subcontractors under subcontracting agreements with the joint ventures. Many of these joint ventures are formed for a specific project. The assets of our joint ventures generally consist almost entirely of cash and receivables (representing amounts due from clients), and the liabilities of our joint ventures generally consist almost entirely of amounts due to the joint venture partners (for services provided by the partners to the joint ventures under their individual subcontracts) and other subcontractors. In general, at any given time, the equity of our joint ventures represents the undistributed profits earned on contracts the joint ventures hold with clients. Very few of our joint ventures have employees or third-party debt or credit facilities. The debt held by the joint ventures is non-recourse to the general credit of Jacobs.
The assets of a joint venture are available for use for the obligations of the particular joint venture and not for general operations of the Company. Our risk of loss on these arrangements is usually shared with our partners. The liability of each partner is usually joint and several, which means that each partner may become liable for the entire risk of loss on the project. Furthermore, on some of our projects, the Company has granted guarantees which may encumber both our contracting subsidiary company and the Company for the entire risk of loss on the project. The Company is unable to estimate the maximum potential amount of future payments that we could be required to make under outstanding performance guarantees related to joint venture projects due to a number of factors, including but not limited to, the nature and extent of any contractual defaults by our joint venture partners, resource availability, potential performance delays caused by the defaults, the location of the projects, and the terms of the related contracts. See Note 19 - Contractual Guarantees, Litigation, Investigations and Insurance for further discussion.
Most of the joint ventures are deemed to be variable interest entities (“VIE”) because they lack sufficient equity to finance the activities of the joint venture. The Company uses a qualitative approach to determine if the Company is the primary beneficiary of the VIE, which considers factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance. These factors include the composition of the governing board, how board decisions are approved, the powers granted to the operational manager(s) and partner that holds that position(s), and to a certain extent, the partner’s economic interest in the joint venture. The Company analyzes each joint venture initially to determine if it should be consolidated or unconsolidated.
Consolidated if the Company is the primary beneficiary of a VIE or holds the majority of voting interests of a non-VIE (and no significant participative rights are available to the other partners).
Unconsolidated if the Company is not the primary beneficiary of a VIE or does not hold the majority of voting interest of a non-VIE.
Our unconsolidated joint ventures (including equity method investments) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable, and impairment losses are recognized for such investments if there is a decline in fair value below carrying value that is considered to be other-than-temporary.
See Note 8- Joint Ventures, VIEs and Other Investments for further discussion.
Fair Value Measurements
Certain amounts included in the accompanying consolidated financial statements are presented at “fair value.” Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants as of the date fair value is determined (the “measurement date”). When determining fair value, we consider the principal or most advantageous market in which we would transact, and we consider only those assumptions we believe a typical market participant would consider when pricing an asset or liability. In measuring fair value, we use the following inputs in the order of priority indicated:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than quoted prices in active markets included in Level 1, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions (e.g., less active markets); and (iii) model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data for substantially the full term of the asset or liability.
Level 3 - Unobservable inputs to the valuation methodology that are significant to the fair value measurement.
The net carrying amounts of cash and cash equivalents, trade receivables and payables and short-term debt approximate fair value due to the short-term nature of these instruments. See Note 9- Borrowings for a discussion of the fair value of long-term debt.
Certain other assets and liabilities, such as forward contracts and interest rate swap agreements we purchased as cash-flow hedges discussed in Note 18- Commitments and Contingencies and Derivative Financial Instruments and the Company's investment in Amentum ordinary shares discussed in Note 14- Discontinued Operations are required to be carried in our Consolidated Financial Statements at Fair Value.
The fair value of the Company’s reporting units (used for purposes of determining whether there is an impairment of the carrying value of goodwill) is determined using an income and market approach. Both approaches require us to make certain estimates and judgments. Under the income approach, fair value is determined by using the discounted cash flows of our reporting units. Under the market approach, the fair values of our reporting units are determined by reference to guideline companies that are reasonably comparable to our reporting units; the fair values are estimated based on the valuation multiples of earnings before taxes, interest, depreciation and amortization associated with the guideline companies. In assessing whether the carrying value of goodwill has been impaired, we utilize the results of both valuation techniques and consider the range of fair values indicated.
With respect to equity-based compensation (i.e., share-based payments), we estimate the fair value of stock options granted to employees and directors using the Black-Scholes option-pricing model. Like all option-pricing models, the Black-Scholes model requires the use of subjective assumptions including (i) the expected volatility of the market price
of the underlying stock, and (ii) the expected term of the award, among others. Accordingly, changes in assumptions and any subsequent adjustments to those assumptions can cause different fair values to be assigned to our future stock option awards. For restricted stock awards (including restricted stock units) containing service and performance conditions, fair value is based on the closing stock price on the date of grant, adjusted for the expected level of achievement for any performance conditions.
The fair values of the assets owned by the various pension plans that the Company sponsors are determined based on the type of asset, consistent with U.S. GAAP. Equity securities are valued by using market observable data such as quoted prices. Publicly traded corporate equity securities are valued at the last reported sale price on the last business day of the year. Securities not traded on the last business day are valued at the last reported bid price. Fixed income investment funds categorized as Level 2 are valued by the trustee using pricing models that use verifiable observable market data (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers, or quoted prices of securities with similar characteristics. Real estate consists primarily of common or collective trusts, with underlying investments in real estate. These investments are valued using the best information available, including quoted market price, market prices for similar assets when available, internal cash flow estimates discounted at an appropriate interest rate, or independent appraisals, as appropriate. Management values insurance contracts and hedge funds using actuarial assumptions and certain values reported by fund managers.
Fair value measurements relating to our business combinations are made primarily using Level 3 inputs including discounted cash flow and to the extent applicable, Monte Carlo simulation techniques. Fair value for the identified intangible assets is generally estimated using inputs primarily for the income approach using the multiple period excess earnings method and the relief from royalties method. The significant assumptions used in estimating fair value include (i) revenue projections of the business, including profitability, (ii) attrition rates and (iii) the estimated discount rate that reflects the level of risk associated with receiving future cash flows. Other personal property assets, such as furniture, fixtures and equipment, are valued using the cost approach, which is based on replacement or reproduction costs of the asset less depreciation. The fair value of the contingent consideration is estimated using a Monte Carlo simulation and the significant assumptions used include projections of revenues and probabilities of meeting those projections. Key inputs to the valuation of the noncontrolling interests include projected cash flows and the expected volatility associated with those cash flows.
The fair values for the asset groups relating to the impairment assessment of long-lived assets (see Note 10- Leases) were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair value include the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflects the level of risk associated with receiving future cash flows.
The methodologies described above and elsewhere in these Notes to Consolidated Financial Statements may produce a fair value measure that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes Level 3 valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement.
Cash Equivalents
We consider all highly liquid investments with original maturities of less than three months to be cash equivalents. Cash equivalents at September 27, 2024 and September 29, 2023 consisted primarily of money market mutual funds and overnight bank deposits.
Receivables, Contract Assets and Contract Liabilities
Receivables include amounts billed, net and unbilled receivables. Amounts billed, net consist of amounts invoiced to clients in accordance with the terms of our client contracts and are shown net of an allowance for expected credit losses. We anticipate that substantially all of such billed amounts will be collected over the next twelve months.
Unbilled receivables and other, which represent an unconditional right to payment subject only to the passage of time in connection with our client contracts, are reclassified to amounts billed when they are billed under the terms of the contract. We anticipate that substantially all of such unbilled amounts will be billed and collected over the next twelve months.
Contract assets represent unbilled amounts where the right to payment is subject to more than merely the passage of time and includes performance-based incentives and services provided ahead of agreed contractual milestones. Contract assets are transferred to unbilled receivables when the right to consideration becomes unconditional and are transferred to amounts billed upon invoicing.
Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. We anticipate that substantially all such amounts will be earned over the next twelve months.
Property, Equipment, and Improvements
Property, equipment and improvements are carried at cost, and are shown net of accumulated depreciation and amortization in the accompanying Consolidated Balance Sheets. Depreciation and amortization are computed primarily by using the straight-line method over the estimated useful lives of the assets. The cost of leasehold improvements is amortized using the straight-line method over the lesser of the estimated useful life of the asset or the remaining term of the related lease. Estimated useful lives range from 20 to 40 years for buildings, from 3 to 10 years for equipment and from 1 to 14 years for leasehold improvements.
Goodwill and Other Intangible Assets
Goodwill represents the excess of the cost of an acquired business over the fair value of the net tangible and intangible assets acquired. Goodwill and intangible assets with indefinite lives are not amortized; instead, on an annual basis we test goodwill and intangible assets with indefinite lives for possible impairment. Intangible assets with finite lives are amortized on a straight-line basis over the useful lives of those assets.
For purposes of impairment testing, goodwill is assigned to the applicable reporting units based on the current reporting structure. We have determined that our operating segments are also our reporting units based on management’s conclusion that the components comprising each of our operating segments share similar economic characteristics and meet the aggregation criteria in accordance with ASC 350.
We perform our annual goodwill impairment assessment as of the first day of the fourth fiscal quarter each year. We begin with the qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the quantitative assessment described below. If it is determined through the evaluation of events or circumstances that the carrying value may not be recoverable, the Company then compares the fair value of the related reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized. For the 2024 fiscal year, we performed a quantitative impairment test of the historical DVS reporting unit as of the beginning of the fourth quarter and determined that the fair value of the reporting unit exceeded its carrying value. For the remaining reporting units, we determined that the fair values significantly exceeded their carrying values and an analysis beyond the qualitative level was not considered necessary.
Impairment of Long-Lived Assets
Our long-lived assets other than goodwill principally consist of right-of-use (ROU) lease assets, property, equipment and improvements, and finite-lived intangible assets. These long-lived assets are evaluated for impairment for each of our asset groups in accordance with ASC 360 by first identifying whether indicators of impairment exist. If such indicators are present, we assess long-lived asset groups for recoverability based on estimated future undiscounted cash flows. For asset groups where the recoverability test fails, the fair value of each asset group is then estimated and compared to its carrying amount. An impairment loss is recognized for the amount by which an asset group’s carrying value exceeds its fair value.
Foreign Currencies
In preparing our Consolidated Financial Statements, it is necessary to translate the financial statements of our subsidiaries operating outside the U.S., which are denominated in currencies other than the U.S. dollar, into the U.S. dollar. In accordance with U.S. GAAP, revenues and expenses of operations outside the U.S. are translated into U.S. dollars using weighted-average exchange rates for the applicable periods being translated while the assets and liabilities of operations outside the U.S. are generally translated into U.S. dollars using period-end exchange rates. The net effect of foreign currency translation adjustments is included in stockholders’ equity as a component of accumulated other comprehensive income (loss) in the accompanying Consolidated Balance Sheets.
Share-Based Payments
We measure the value of services received from employees and directors in exchange for an award of an equity instrument based on the grant-date fair value of the award. The fair value is recognized as a non-cash cost on a straight-line basis over the period the individual provides services, which is typically the vesting period of the award with the exception of awards containing an internal performance measure, such as Earnings Per Share growth and Return on Invested Capital, which is recognized on a straight-line basis over the vesting period subject to the probability of meeting the performance requirements and adjusted for the number of shares expected to be earned. The cost of these awards is recorded in selling, general and administrative expense in the accompanying Consolidated Statements of Earnings.
Concentrations of Credit Risk
Our cash balances and cash equivalents are maintained in accounts held by major banks and financial institutions located in North America, South America, Europe, the Middle East, India, Australia, Africa and Asia. In the normal course of business, and consistent with industry practices, we grant credit to our clients without requiring collateral. Concentrations of credit risk is the risk that, if we extend a significant amount of credit to clients in a specific geographic area or industry, we may experience disproportionately high levels of default if those clients are adversely affected by factors particular to their geographic area or industry. Concentrations of credit risk relative to trade receivables are limited due to our diverse client base, which includes the U.S. federal government and multi-national corporations operating in a broad range of industries and geographic areas. Additionally, in order to mitigate credit risk, we continually evaluate the credit worthiness of our major commercial clients.
Leases
The Company accounts for its leases in accordance with ASC 842, Leases ("ASC 842"). ASC 842 requires lessees to recognize assets and liabilities for most leases. The Company determines if an arrangement is a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of an identified asset for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract, and (2) the customer has the right to control the use of the identified asset. Lessees are required to classify leases as either finance or operating leases. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease.
The Company’s right-of use assets and lease liabilities relate to real estate, project assets used in connection with long-term construction contracts, IT assets and vehicles. The Company’s leases have remaining lease terms of less than one year to nineteen years. The Company’s lease obligations are primarily for the use of office space and are primarily operating leases. Certain of the Company’s leases contain renewal, extension, or termination options. The Company assesses each option on an individual basis and will only include options reasonably certain of exercise in the lease term. The Company generally considers the base term to be the term provided in the contract. None of the Company’s lease agreements contain material options to purchase the leased property, material residual value guarantees, or material restrictions or covenants.
Long-term project asset and vehicle leases (leases with terms greater than twelve months), along with all real estate and IT asset leases, are recorded on the consolidated balance sheet at the present value of the minimum lease payments not yet paid. Because the Company primarily acts as a lessee and the rates implicit in its leases are not readily determinable, the Company generally uses its incremental borrowing rate on the lease commencement date to calculate the present value of future lease payments. Certain leases include payments that are based solely on an index or rate. These variable lease payments are included in the calculation of the ROU asset and lease liability and are initially measured using the index or rate at the lease commencement date. Other variable lease payments, such as payments based on use and for property taxes, insurance, or common area maintenance that are based on actual assessments are excluded from the ROU asset and lease liability and are expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any deferred rent, lease prepayments and initial direct costs of obtaining the lease, such as commissions.
Certain lease contracts contain non-lease components such as maintenance and utilities. The Company has made an accounting policy election, as allowed under ASC 842-10-15-37 and discussed above, to capitalize both the lease component and non-lease components of its contracts as a single lease component for all of its right-of-use assets.
Short-term project asset and vehicle leases (project asset and vehicle leases with an initial term of twelve months or less or leases that are cancellable by the lessee and lessor without significant penalties) are not recorded on the consolidated balance sheet and are expensed on a straight-line basis over the lease term. The majority of the Company’s short-term leases relate to equipment used on construction projects. These leases are entered into at agreed upon hourly, daily, weekly or monthly rental rates for an unspecified duration and typically have a termination for convenience provision. Such equipment leases are considered short-term in nature unless it is reasonably certain that the equipment will be leased for a term greater than twelve months.
Pensions
We use certain assumptions and estimates in order to calculate periodic pension cost and the value of the assets and liabilities of our pension plans. These assumptions involve discount rates, investment returns, and projected salary increases, among others. Changes in the actuarial assumptions may have a material effect on the plans’ liabilities and the projected pension expense.
We use a corridor approach to amortize actuarial gains and losses. Under this approach, net gains or losses in excess of ten percent of the larger of the pension benefit obligation or the market-related value of the assets are amortized on a straight-line basis. The period of amortization is the average remaining service of active participants who are expected to receive benefits under certain plans and the average remaining future lifetime of plan participants for certain plans.
We measure our defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end, which is September 27, 2024 as the alternative measurement date in accordance with FASB guidance ASU 2015-04, Compensation Retirement Benefit (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Asset. This guidance allows employers with fiscal year ends that do not coincide with a calendar month end to make an accounting policy election to measure defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end.
Redeemable Noncontrolling Interests
In connection with the PA Consulting investment in March 2021, the Company recorded redeemable noncontrolling interests, representing the interest holders' 35% equity interest in the form of preferred and common shares of PA Consulting. The preferred shares are entitled to a cumulative annual compounding 12% dividend based on the outstanding preferred share subscription price. These noncontrolling interest holders have certain option rights to put the preferred and common share interests back to the Company at a value based on the fair value of PA Consulting (the redemption values). The primary inputs and assumptions impacting the fair value of PA Consulting include projections of revenue and earnings before interest, taxes, depreciation and amortization and discount rates applied thereto. Additionally, the Company has an option to call the interests for certain individual shareholders in certain circumstances. Because the interests are redeemable at the option of the holders and not solely within the control of the Company, the Company classified the interests in redeemable noncontrolling interests within its Consolidated Balance Sheet at their redemption values. The optional redemption features may become exercisable no earlier than five years from the March 2, 2021 closing date, or upon the occurrence of certain other events.
The Company has deemed these interests probable of becoming redeemable in the future and requiring their measurement at the greater of (i) the redemption amount that would be paid if settlement occurred at the balance sheet date, or (ii) the historical value resulting from the original acquisition date fair value plus the impact of any earnings or loss attribution amounts, including dividends. The fair value of the PA Consulting redeemable noncontrolling interest is determined using a combination of the income and market approaches. Under the income approach, fair value is determined by using the projected discounted cash flows of PA Consulting. Under the market approach, the fair value is determined by reference to guideline companies that are reasonably comparable to PA Consulting; the fair value is estimated based on the valuation multiples of earnings before interest, taxes, depreciation and amortization.
Further, to the extent redemption values exceed historical values of the interests, changes in redemption amounts are recognized as changes to redeemable noncontrolling interests with an offsetting change in consolidated retained earnings. Additionally, particular to the preference share and in certain circumstances the ordinary share components of redeemable noncontrolling interests, such changes in consolidated retained earnings could also be reflected as a corresponding adjustment to net earnings attributable to Jacobs for purposes of the calculation of consolidated earnings per share attributable to common shareholders.
Income Taxes
We determine our consolidated income tax expense using the asset and liability method prescribed by U.S. GAAP. Under this method, deferred tax assets and liabilities are recognized for the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and income tax purposes. Such deferred tax assets and liabilities are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. If and when we determine that a deferred tax asset will not be realized for its full amount, we will recognize and record a valuation allowance with a corresponding charge to earnings. Judgment is required in determining our provision for income taxes. In the normal course of business, we may engage in numerous transactions every day for which the ultimate tax outcome (including the period in which the transaction will ultimately be included in taxable income or deducted as an expense) is uncertain. Additionally, we file income, franchise, gross receipts and similar tax returns in many jurisdictions. Our tax returns are subject to audit and investigation by the Internal Revenue Service, most states in the U.S., and by various government agencies representing many jurisdictions outside the U.S.
The Tax Cuts and Jobs Act of 2017 (the "Tax Act") contains a provision which subjects a U.S. parent of a foreign subsidiary to current U.S. tax on its global intangible low–taxed income (“GILTI”). The GILTI income is eligible for a deduction, which lowers the effective tax rate of GILTI to 10.5% for calendar years 2018 through 2025 and 13.125% after 2025. The Company will report the tax impact of GILTI as a period cost when incurred. Accordingly, the Company is not providing deferred taxes for basis differences expected to reverse as GILTI.
Contractual Guarantees, Litigation, Investigations and Insurance
In the normal course of business, we are subject to certain contractual guarantees and litigation. We record in the Consolidated Balance Sheets amounts representing our estimated liability relating to such guarantees, litigation and insurance claims. Guarantees are accounted for in accordance with ASC 460-10, Guarantees, at fair value at the inception of the guarantee. We perform an analysis to determine the level of reserves to establish for both insurance-related claims that are known and have been asserted against us as well as for insurance-related claims that are believed to have been incurred based on actuarial analysis but have not yet been reported to our claims administrators as of the respective
balance sheet dates. We include any adjustments to such insurance reserves in our Consolidated Statements of Earnings. In addition, as a contractor providing services to various agencies of the U.S. federal government, we are subject to many levels of audits, investigations, and claims by, or on behalf of, the U.S. federal government with respect to contract performance, pricing, costs, cost allocations and procurement practices. We adjust revenues based upon the amounts we expect to realize considering the effects of any client audits or governmental investigations.
Business Combinations
U.S. GAAP requires that the purchase price paid for business combinations accounted for using the acquisition method be allocated to the assets and liabilities acquired based on their respective fair values. The Company makes certain estimates and judgments relating to other assets and liabilities acquired as well as any identifiable intangible assets acquired.
Use of Estimates and Assumptions
The preparation of financial statements in conformity with U.S. GAAP requires us to employ estimates and make assumptions that affect the reported amounts of certain assets and liabilities; the revenues and expenses reported for the periods covered by the financial statements; and certain amounts disclosed in these Notes to the Consolidated Financial Statements. Although such estimates and assumptions are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available and past experience, actual results could differ significantly from those estimates and assumptions. Our estimates, judgments and assumptions are evaluated periodically and adjusted accordingly.
New Accounting Pronouncements
ASU 2023-09, Income Taxes, (Topic 740): Improvements to Income Tax Disclosures, provides qualitative and quantitative updates to the Company's effective income tax rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied prospectively; however, retrospective application is also permitted. ASU 2023-09 will be effective for the Company's annual fiscal 2026 period. The Company has identified and is implementing changes to processes and internal controls to meet the standard’s updated reporting and disclosure requirements.
ASU 2023-07, Segment Reporting, (Topic 280): Improvements to Reportable Segment Disclosures, 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 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and the amendments in this update are required to be applied on a retrospective basis. ASU 2023-07 will be effective for the Company's annual fiscal 2025 period. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
ASU 2023-06, Disclosure Improvements: Amendments - Codification Amendments in Response to the Disclosure Update and Simplification Initiative of the Securities and Exchange Commission ("SEC"). The Financial Accounting Standards Board issued the standard to introduce changes to US GAAP that originate in either SEC Regulation S-X or S-K, which are rules about the form and content of financial reports filed with the SEC. The provisions of the standard are contingent upon instances where the SEC removes the related disclosure provisions from Regulation S-X and S-K. The Company does not expect that the application of this standard will have a material impact on our consolidated financial statements and related disclosures.

Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. Revenue recognized for the year ended September 27, 2024 that was previously included in the contract liability balance on September 29, 2023 was $521 million. Revenue recognized for the year ended September 29, 2023 that was previously included in the contract liability balance on September 30, 2022 was $449 million.
Remaining Performance Obligations
The Company’s remaining performance obligations as of September 27, 2024 represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company had approximately $13.7 billion in remaining performance obligations as of September 27, 2024. The Company expects to recognize 53% of our remaining performance obligations within the next twelve months and the remaining 47% thereafter. The majority of the remaining performance obligations after the first twelve months are expected to be recognized over a four-year period.
Although our remaining performance obligations reflect business volumes that are considered to be firm, normal business activities including scope adjustments, deferrals or cancellations may occur that impact volume or expected timing of their recognition. Remaining performance obligations are adjusted to reflect any known project cancellations, revisions to project scope and cost, foreign currency exchange fluctuations and project deferrals, as appropriate.

Earnings Per Share Reconciliation [Abstract]  
Earnings Per Share and Certain Related Information Earnings Per Share and Certain Related Information
Basic and Diluted Earnings Per Share
Basic and diluted earnings per share (“EPS”) are computed using the two-class method, which is an earnings allocation method that determines EPS for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings. Net earnings used for the purpose of determining basic and diluted EPS is determined by taking net earnings, less earnings available to participating securities and the preferred redeemable noncontrolling interests redemption value adjustment associated with the PA Consulting transaction in fiscal 2024.
The following table reconciles the denominator used to compute basic EPS to the denominator used to compute diluted EPS for the years ended September 27, 2024, September 29, 2023 and September 30, 2022 (in thousands):

Share Repurchases
On January 16, 2020, the Company's Board of Directors authorized a share repurchase program of up to $1.0 billion of the Company's common stock (the "2020 Repurchase Authorization"). In the fourth quarter of fiscal 2021 the Company launched an accelerated share repurchase program by advancing $250 million to a financial institution in a privately negotiated transaction, with final non-cash settlement on the program during the first quarter of fiscal 2022 of 342,054 shares.
The 2020 Repurchase Authorization expired on January 15, 2023. On January 25, 2023, the Company's Board of Directors authorized an incremental share repurchase program of up to $1.0 billion of the Company's common stock, to expire on January 25, 2026 (the "2023 Repurchase Authorization"). At September 27, 2024, the Company had $472.2 million remaining under the 2023 Repurchase Authorization.
The following table summarizes repurchase activity under the 2020 Repurchase Authorization during fiscal 2023 through expiration during the second fiscal quarter of 2023:

Our share repurchase programs do not obligate the Company to purchase any shares. Share repurchases may be executed through various means including, without limitation, accelerated share repurchases, open market transactions, privately negotiated transactions, purchases pursuant to a Rule 10b5-1 plan or otherwise. The authorization for the share repurchase programs may be terminated, increased or decreased by the Company’s Board of Directors in its discretion at any time. The timing, amount and manner of share repurchases may depend upon market conditions and economic circumstances, availability of investment opportunities, the availability and costs of financing, currency fluctuations, the market price of the Company's common stock, other uses of capital and other factors.
Common and Preferred Stock
Jacobs is authorized to issue two classes of capital stock designated “common stock” and “preferred stock” (each has a par value of $1.00 per share). The preferred stock may be issued in one or more series. The number of shares to be included in a series as well as each series’ designation, relative powers, dividend and other preferences, rights and qualifications, redemption provisions and restrictions are to be fixed by the Company’s Board of Directors at the time each series is issued. Except as may be provided by the Company’s Board of Directors in a preferred stock designation, or otherwise provided for by statute, the holders of shares of common stock have the exclusive right to vote for the election of directors and on all other matters requiring stockholder action. The holders of shares of common stock are entitled to dividends if and when declared by the Company’s Board of Directors from whatever assets are legally available for that purpose.
Dividends
On September 26, 2024, the Company’s Board of Directors declared a quarterly dividend of $0.29 per share of the Company’s common stock, which was paid on November 22, 2024, to shareholders of record on the close of business on October 25, 2024. Future dividend declarations are subject to review and approval by the Company’s Board of Directors.

Valuation allowances are recorded to reduce deferred tax assets to the amount that is more likely than not to be realized based on an assessment of positive and negative evidence, including estimates of future taxable income necessary to realize future deductible amounts. The Company's total valuation allowances were $217.4 million at September 27, 2024 and $199.9 million at September 29, 2023. This change in the valuation allowances is attributable primarily to a $10.3 million valuation allowance increase due to the change in the realizability of foreign tax credits, a $51.2 million increase due to a capital loss in Australia, offset by a $20.3 million valuation allowance decrease as a result of expiring foreign tax credits and a $26.0 million net operating loss utilization for other foreign assessable income, with an increase of $2.2 million related to various other items.
At September 27, 2024 and September 29, 2023, the Company's domestic and international net operating loss (NOL) carryforwards totaled $915.6 million and $918.7 million, resulting in an NOL deferred tax asset of $259.3 million and $265.4 million, respectively. The Company's net operating losses have various expiration periods between 2025 and indefinite periods. At September 27, 2024, the Company has foreign tax credit carryforwards of $42.4 million (which has a partial valuation allowance of $25.1 million) with $9.5 million expected to expire in 2025 and the remaining by 2033.

We do not record a deferred tax liability for unremitted earnings of our foreign subsidiaries to the extent that the earnings meet the indefinite reversal criteria. The decision as to the amount of unremitted earnings that we intend to maintain in non-U.S. subsidiaries considers items including, but not limited to, forecasts and budgets of financial needs of cash for working capital, liquidity plans, and expected cash requirements in the U.S. As of September 27, 2024, we had not recognized a deferred tax liability on approximately $194.4 million of undistributed earnings for certain foreign subsidiaries, because these earnings are intended to be indefinitely reinvested. If such earnings were distributed, some countries may impose additional taxes. The Company also has various long-term foreign currency denominated intercompany loans not anticipated to be settled in the foreseeable future, which are considered indefinitely reinvested as
they are viewed as part of the Company’s net investment in the subsidiary. The unrecognized deferred tax liability (the amount payable if distributed) for both the unremitted earnings and intercompany loans, which are indefinitely reinvested, is approximately $15.5 million.
In December 2021, the Organization for Economic Cooperation and Development “"OEC”") released the Pillar Two Model Rules (also referred to as the global minimum tax or Global Anti-Base Erosion “"GloBE”" rules), which were designed to ensure large multinational enterprises pay a minimum 15 percent level of tax on the income arising in each jurisdiction in which they operate. Several jurisdictions in which we operate have enacted these rules, which are effective for the first quarter of the fiscal year ending September 26, 2025. The Company is continually monitoring developments and evaluating the potential impacts. At this time, the Company does not anticipate a material impact to income tax expense as a result of implementation of these rules.
The Company accounts for unrecognized tax benefits in accordance with ASC Topic 740, Income Taxes. It accounts for interest and penalties on unrecognized tax benefits as interest and penalties reported above the line (i.e., not as part of income tax expense). The main driver of the current year increase relates to uncertain tax positions on R&D credits, which is offset by the release of uncertain tax positions whose statute of limitation expired during FY24. At September 27, 2024 and September 29, 2023, if recognized, $27.1 million and $28.4 million, respectively, would affect the Company’s consolidated effective income tax rate. The Company had $22.6 million and $37.7 million in accrued interest and penalties at September 27, 2024 and September 29, 2023, respectively. The Company estimates that, within twelve months, we may realize a decrease in our uncertain tax positions of approximately $4.9 million as a result of concluding various tax audits and closing tax years.
The amount of income taxes the Company pays is subject to ongoing audits by tax jurisdictions around the world. In the normal course of business, the Company is subject to examination by taxing authorities worldwide, including such major jurisdictions as Australia, Canada, India, the Netherlands, the United Kingdom, and the United States. As of September 27, 2024, the Company has certain US tax returns open to audit from 2009 through 2011 and 2019 through 2023. For the jurisdictions outside the US, primarily UK and Australia, various returns are open for audit for tax years 2014 through 2023. Although the Company believes the reserves established for the tax positions are reasonable, the outcome of tax audits could be materially different, both favorably and unfavorably.
The following table presents the reconciliation of the beginning and ending amount of unrecognized tax benefits, for continuing operations, for the years ended September 27, 2024, September 29, 2023 and September 30, 2022 (in thousands):

For those joint ventures accounted for under the equity method, the Company's investment balances for the joint venture is included in other noncurrent assets: miscellaneous on the balance sheet and the Company’s pro rata share of net income is included in revenue. In limited cases, there are basis differences between the equity in the joint venture and Jacobs' investment created when Jacobs purchased their share of the joint venture. These basis differences are amortized based on an internal allocation to underlying net assets, excluding allocations to goodwill. Our investments in equity method joint ventures on the Consolidated Balance Sheets as of September 27, 2024 and September 29, 2023 were a net asset of $36.6 million and $32.1 million, respectively. During the years ended September 27, 2024, September 29, 2023, and September 30, 2022, we recognized income from equity method joint ventures of $11.9 million, $3.1 million, and $8.1 million, respectively.
Accounts receivable from unconsolidated joint ventures accounted for under the equity method is $12.3 million and $11.4 million as of September 27, 2024 and September 29, 2023, respectively.

Revolving Credit Facility and Term Loans
The Company and certain of its subsidiaries maintain a sustainability-linked $2.25 billion unsecured revolving credit facility (the “Revolving Credit Facility”) established under a third amended and restated credit agreement, dated February 6, 2023 (the "Revolving Credit Agreement"), among Jacobs and certain of its subsidiaries as borrowers and a syndicate of U.S. and international banks and financial institutions. The credit extensions under the Revolving Credit Facility can be funded in U.S dollars, British Sterling, Euros, Canadian dollars, Australian dollars, Swedish Krona, Singapore dollars and other agreed upon alternative currencies. The Revolving Credit Agreement also provides for a financial letter of credit sub facility of $400.0 million, permits performance letters of credit, and provides for a $100.0 million sub facility for swing line loans. Letters of credit are subject to fees based on the Company’s Consolidated Leverage Ratio and Debt Rating, whichever is more favorable to the Company.
The Revolving Credit Agreement amended and restated the second amended restated credit agreement dated March 27, 2019, by and among JEGI and certain of its subsidiaries and a syndicate of banks and financial institutions, in order to, among other things, (a) extend the maturity date of the Revolving Credit Facility to February 6, 2028, (b) replace and adjust interest rates based on market conditions and incorporate a sustainability-linked pricing adjustment, (c) revise the commitment fee on the unused portion of the facility to a range of 0.10% to 0.25% depending on the higher of the pricing level associated with JEGI's Debt Rating or the Consolidated Leverage Ratio, (d) increase the Consolidated Leverage Ratio financial covenant to 3.50:1.00 (subject to temporary increases to 4.00:1.00 following the closing of certain material acquisitions), (e) eliminate the net worth financial covenant and (f) add the Company as a guarantor of the obligations of JEGI and its subsidiaries under the Revolving Credit Agreement.
The Company and JEGI maintain an unsecured delayed draft term loan facility (the “2021 Term Loan Facility”) established under an amended and restated term loan agreement dated February 6, 2023 (the "Amended and Restated Term Loan Agreement"), by and among the Company and JEGI and a syndicate of banks and financial institutions. JEGI borrowed $200.0 million and £650.0 million of term loans under the 2021 Term Loan Facility (reflecting scheduled maturities in February 2026 and September 2025, respectively) and the proceeds of such term loans were used primarily to fund JEGI's investment in PA Consulting. The Amended and Restated Term Loan Agreement amended and restated the term loan agreement dated January 15, 2021, by and among JEGI and a syndicate of U.S. banks and financial institutions to, among other things: (a) extend the maturity date of the U.S. dollar term loan to February 6, 2026 and the British sterling term loan to September 1, 2025, (b) replace and adjust interest rates based on market conditions and incorporate a sustainability-linked pricing adjustment, (c) increase the Consolidated Leverage Ratio financial covenant to 3.50:1.00 (subject to temporary increases to 4.00:1.00 following the closing of certain material acquisitions), (d) eliminate the net worth financial covenant, and (e) add Jacobs as a guarantor of the obligations of JEGI under the Amended and Restated Term Loan Agreement. The 2021 Term Loan facility matures in September 2025 and the related outstanding balances under this facility have been reclassified to current maturities of long-term debt in the Company’s September 27, 2024
consolidated balance sheet in the current quarter.
During the fourth quarter of fiscal 2023, the Company repaid $80.0 million of the USD portion of the 2021 Term Loan Facility.
On March 25, 2020, JEGI and Jacobs U.K., a wholly owned subsidiary of JEGI, entered into a term loan agreement (the "2020 Term Loan Agreement") with a syndicate of banks and financial institutions, which provides for an unsecured term loan facility (the “2020 Term Loan Facility”). Under the 2020 Term Loan Facility, JEGI borrowed an aggregate principal amount of $730.0 million and Jacobs U.K. borrowed an aggregate principal amount of £250.0 million. The proceeds of the term loans were used to repay an existing term loan with a maturity date of June 2020 and for general corporate purposes. On February 6, 2023, the 2020 Term Loan Agreement was amended to, among other things: (a) replace and adjust interest rates based on market conditions and incorporate a sustainability-linked pricing adjustment, (b) increase the Consolidated Leverage Ratio financial covenant to 3.50:1.00 (subject to temporary increases to 4.00:1.00 following the closing of certain material acquisitions), (c) eliminate the net worth financial covenant, and (d) add Jacobs as a guarantor of the obligations of JEGI and Jacobs U.K. During the fourth quarter of fiscal 2024, the Company repaid the outstanding USD and GBP portions of the 2020 Term Loan Facility.
The 2020 Term Loan Facility and the 2021 Term Loan Facility were together referred to as the "Term Loan Facilities".
In the fourth quarter of fiscal 2022, the Revolving Credit Facility and Term Loan Facilities were amended to permit the Holding Company Reorganization.
On December 20, 2023, the Revolving Credit Facility and Term Loan Facilities were amended to adjust the point in
time at which certain compliance thresholds are tested in connection with the Separation Transaction.

On April 10, 2024, the Term Loan Facilities were amended to permit the potential exchange of Jacobs' retained
equity stake in the combined company after the Separation Transaction for the effective repayment of a portion of the
Term Loan Facilities. Additionally, during the fourth quarter of fiscal 2024, in connection with the Separation Transaction, the Company repaid the outstanding USD and GBP portions of the 2020 Term Loan Facility.
We were in compliance with the covenants under the Revolving Credit Facility and Term Loan Facilities at September 27, 2024.
5.90% Bonds, due 2033
On February 16, 2023, JEGI completed an offering of $500 million aggregate principal amount of 5.90% Bonds due 2033 (the “5.90% Bonds”). The 5.90% Bonds are fully and unconditionally guaranteed by the Company (the "5.90% Bond Guarantee”). The 5.90% Bonds and the 5.90% Bonds Guarantee were offered pursuant to a prospectus supplement, dated February 13, 2023, to the prospectus dated February 6, 2023, that forms a part of the Company's and JEGI’s automatic shelf registration statement on Form S-3ASR previously filed with the Securities and Exchange Commission, and were issued pursuant to the Indenture, dated as of February 16, 2023 (the "Indenture"), between JEGI, as issuer, the Company, as guarantor, and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as amended and supplemented by the First Supplemental Indenture, dated as of February 16, 2023 (the “First Supplemental Indenture”). Interest on the 5.90% Bonds is payable semi-annually in arrears on each March 1 and September 1, commencing on September 1, 2023, until maturity. The 5.90% Bonds bear interest at 5.9% per annum, subject to adjustments as discussed in note (5) to the table above.
Prior to December 1, 2032 (the “5.90% Bonds Par Call Date”), JEGI may redeem the 5.90% Bonds at its option, in whole or in part, at any time and from time to time, at the redemption price calculated by JEGI (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the 5.90% Bonds being redeemed, assuming that such 5.90% Bonds matured on the 5.90% Bonds Par Call Date, discounted to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate (as defined in the First Supplemental Indenture) plus 35 basis points, less (b) interest accrued to the redemption date, and (2) 100% of the principal amount of such 5.90% Bonds to be redeemed, plus, in either case, accrued and unpaid interest on the 5.90% Bonds, if any, to, but excluding, the redemption date. At any time and from time to time on or after the 5.90% Bonds Par Call Date, JEGI may redeem the 5.90% Bonds, at its option, in whole or in part, at a redemption price equal to 100% of the principal amount of the 5.90% Bonds to be redeemed, plus accrued and unpaid interest thereon, if any, up to, but excluding, the redemption date.
6.35% Bonds, due 2028
On August 18, 2023, JEGI completed an offering of $600 million aggregate principal amount of 6.35% Bonds due 2028 (the “6.35% Bonds”). The 6.35% Bonds are fully and unconditionally guaranteed by the Company (the “6.35% Bonds Guarantee”). The 6.35% Bonds and the 6.35% Bonds Guarantee were offered pursuant to a prospectus supplement, dated August 15, 2023, to the prospectus dated February 6, 2023, that forms a part of the Company and JEGI’s automatic shelf registration statement on Form S-3ASR previously filed with the Securities and Exchange Commission, and were issued pursuant to the Indenture, as amended and supplemented by the Second Supplemental Indenture, dated as of August 18, 2023 (the “Second Supplemental Indenture”). Interest on the 6.35% Bonds is payable semi-annually in arrears on each February 18 and August 18, commencing on February 18, 2024, until maturity. The Notes will bear interest at a rate of 6.35% per annum and will mature on August 18, 2028. The 6.35% Bonds bear interest at 6.35% per annum.
Prior to July 18, 2028 (the “6.35% Bonds Par Call Date”), JEGI may redeem the 6.35% Bonds at its option, in whole or in part, at any time and from time to time, at the redemption price calculated by JEGI (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the 6.35% Bonds being redeemed, assuming that such 6.35% Bonds matured on the 6.35% Bonds Par Call Date, discounted to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate (as defined in the Second Supplemental Indenture) plus 30 basis points, less (b) interest accrued to the redemption date, and (2) 100% of the principal amount of such 6.35% Bonds to be redeemed, plus, in either case, accrued and unpaid interest on the 6.35% Bonds, if any, to, but excluding, the redemption date. At any time and from time to time on or after the 6.35% Bonds Par Call Date, JEGI may redeem the 6.35% Bonds, at its option, in whole or in part, at a redemption price equal to 100% of the principal amount of the 6.35% Bonds to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.
We believe the carrying value of the Revolving Credit Facility, the Term Loan Facilities and other debt approximates fair value based on the interest rates and scheduled maturities applicable to the outstanding borrowings. At September 27, 2024, the fair value of the 5.9% Bonds and the 6.35% Bonds is estimated to be $521.9 million and $639.7 million, respectively, based on Level 2 inputs. The fair value is determined by discounting future cash flows using interest rates available for issuances with similar terms and average maturities.
Other Arrangements
The Company has issued $0.5 million in letters of credit under the Revolving Credit Facility, leaving $2.11 billion of available borrowing capacity under the Revolving Credit Facility at September 27, 2024. In addition, the Company had issued $305.7 million under separate, committed and uncommitted letter-of-credit facilities for total issued letters of credit of $306.2 million at September 27, 2024. 
During fiscal 2022, the Company entered into two treasury lock agreements with an aggregate notional value of $500.0 million to manage its expected interest rate exposure in anticipation of issuing up to $500 million of fixed rate debt. On February 13, 2023 and with the issuance of the 5.90% Bonds, the Company settled these treasury lock agreements. See Note 18- Commitments and Contingencies and Derivative Financial Instruments for more discussion around this transaction.
During fiscal 2020, the Company entered into interest rate and cross currency derivative contracts to swap a portion of our variable rate debt to fixed rate debt. See Note 18- Commitments and Contingencies and Derivative Financial Instruments for discussion regarding the Company's derivative instruments.

Right-of-Use and Other Long-Lived Asset Impairment
During fiscal 2023, as a result of the Company's transformation initiatives, including the changing nature of the Company's use of office space for its workforce, the Company evaluated its existing real estate lease portfolio. These initiatives resulted in the abandonment of certain leased office spaces and the establishment of a formal plan to sublease certain other leased spaces that will no longer be utilized by the Company. In connection with the Company’s actions related to these initiatives, the Company evaluated certain of its lease right-of-use assets and related property, equipment and leasehold improvements for impairment under ASC 360.

As a result of the analysis, the Company recognized impairment losses of $46.7 million and $76.1 million for the fiscal years ended September 29, 2023 and September 30, 2022, which are included in selling, general and administrative expenses in the accompanying statements of earnings. The impairment losses recorded include $40.9 million and $58.5 million related to right-of-use lease assets and $5.8 million and $17.6 million related to other long-lived assets, including property, equipment & improvements and leasehold improvements for the fiscal year ended September 29, 2023 and September 30, 2022, respectively.

The fair values for the asset groups relating to the impaired long-lived assets were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair value include the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflect the level of risk associated with receiving future cash flows.

Right-of-Use and Other Long-Lived Asset Impairment
During fiscal 2023, as a result of the Company's transformation initiatives, including the changing nature of the Company's use of office space for its workforce, the Company evaluated its existing real estate lease portfolio. These initiatives resulted in the abandonment of certain leased office spaces and the establishment of a formal plan to sublease certain other leased spaces that will no longer be utilized by the Company. In connection with the Company’s actions related to these initiatives, the Company evaluated certain of its lease right-of-use assets and related property, equipment and leasehold improvements for impairment under ASC 360.

As a result of the analysis, the Company recognized impairment losses of $46.7 million and $76.1 million for the fiscal years ended September 29, 2023 and September 30, 2022, which are included in selling, general and administrative expenses in the accompanying statements of earnings. The impairment losses recorded include $40.9 million and $58.5 million related to right-of-use lease assets and $5.8 million and $17.6 million related to other long-lived assets, including property, equipment & improvements and leasehold improvements for the fiscal year ended September 29, 2023 and September 30, 2022, respectively.

The fair values for the asset groups relating to the impaired long-lived assets were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair value include the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflect the level of risk associated with receiving future cash flows.

Employee Stock Purchase Plans
Under the Company's stock purchase plans, eligible employees who elect to participate in these plans are granted the right to purchase shares of the common stock of Jacobs at a discount that is limited to 5% of the per-share market value on the day shares are sold to employees.
The following table summarizes the stock issuance activity under the plans for the fiscal years ended September 27, 2024, September 29, 2023 and September 30, 2022:

At September 27, 2024, there remains 2,199,429 shares reserved for issuance under the Company's stock purchase plans.
Stock Incentive Plans
We also sponsor the 2023 Stock Incentive Plan, as amended and restated (the "2023 SIP") and the 1999 Outside Director Stock Plan, as amended and restated (the "1999 ODSP") as well as the StreetLight 2011 Stock Plan (the "StreetLight Plan"). The 2023 SIP provides for the issuance of incentive stock options, non-qualified stock options, share appreciation rights ("SARs"), restricted stock and restricted stock units to employees. The 1999 ODSP provides for awards of shares of common stock, restricted stock, restricted stock units and grants of non-qualified stock options to our outside (i.e., nonemployee) directors. Together the 2023 SIP and 1999 ODSP plans are known as the "Stock Incentive Plans". The StreetLight Plan provides for the issuance of incentive stock options, nonstatutory stock options and restricted stock to employees. The StreetLight Plan is frozen for new awards effective February 4, 2022. The following table sets forth certain information about the Stock Incentive Plans:

Effective September 28, 2012 until January 23, 2023, all grants of shares under the predecessor to the 2023 SIP were issued on a fungible basis. An award other than an option or SAR was granted on a 1.92-to-1.00 basis (“Fungible”). An award of an option or SAR is granted on a 1-to-1 basis (“Not Fungible”). Effective January 24, 2023, at which time the 2023 SIP was adopted, all awards are granted on a 1-to-1 basis.
In connection with the Separation Transaction, outstanding awards under the Stock Incentive Plans were converted into adjusted Jacobs awards for employees who continued employment with Jacobs after the closing and all employees who separated from employment prior to the closing or Amentum awards for CMS and C&I employees who transferred to Amentum and, in each case, the adjustment methodology was intended to preserve the value of the awards immediately prior to the Separation Transaction when measured immediately after the Separation Transaction. The outstanding Jacobs awards will continue to have the same terms and conditions. The adjustment to the awards did not result in material incremental compensation expense.
At September 27, 2024, the amount of compensation cost relating to non-vested awards not yet recognized in the financial statements is approximately $80.3 million. The majority of these unrecognized compensation costs will be recognized by the first quarter of fiscal 2027. The weighted average remaining contractual term of options currently exercisable is 2.2 years.

Savings and Deferred Compensation Plans Savings and Deferred Compensation Plans
Savings Plans
We sponsor various defined contribution savings plans which allow participants to make voluntary contributions by salary deduction. Such plans cover substantially all of our domestic, nonunion employees in the U.S. and are qualified under Section 401(k) of the U.S. Internal Revenue Code. Similar plans outside the U.S. cover various groups of employees of our international subsidiaries and affiliates. Several of these plans allow the Company to match, on a voluntary basis, a portion of the employee contributions. The following table presents the Company’s contributions to these savings plans for the years ended September 27, 2024, September 29, 2023 and September 30, 2022 (in thousands):

$192,588 $160,256 $136,231 
Deferred Compensation Plans
Our non-qualified deferred compensation programs provide benefits payable to directors, officers, and certain key employees or their designated beneficiaries at specified future dates, upon retirement, or death. The plans are unfunded; therefore, benefits are paid from the general assets of the Company. Participants' cash deferrals earn a return based on the participants' selection of investments in several hypothetical investment options. Participants are also able to defer stock based compensation in the plans, which must remain invested in Company stock and are distributed in shares of Jacobs common stock. Since no investment diversification is permitted, changes in the fair value of Jacobs' common stock are not recognized. For the deferred compensation held in company stock, the number of shares needed to settle the liability is included in the denominator in both the basic and diluted earnings per share calculations. The following table presents the amount charged to (income)/expense for the Company’s deferred compensation plans for the years ended September 27, 2024, September 29, 2023 and September 30, 2022 (in thousands):

Retirement Benefits [Abstract]  
Pension and Other Post Retirement Benefit Plans Pension and Other Post Retirement Benefit Plans
Company-Only Sponsored Plans
We sponsor various defined benefit pension and other post retirement plans covering employees of certain U.S. and international subsidiaries. The pension plans provide pension benefits that are based on the employee’s compensation and years of service. Our funding policy varies by country and plan according to applicable local funding requirements and plan-specific funding agreements.
The accounting for pension and other post retirement benefit plans requires the use of assumptions and estimates in order to calculate periodic benefit cost and the value of the plans’ assets and benefit obligations. These assumptions include discount rates, investment returns, and projected salary increases, among others. The discount rates used in valuing the plans' benefit obligations were determined with reference to high quality corporate and government bonds that are appropriately matched to the duration of each plan's obligations. The expected long-term rate of return on plan assets is generally based on using country-specific simulation models which select a single outcome for expected return based on the target asset allocation. The expected long-term rates of return used in the valuation are the annual average
returns generated by these assumptions over a 20-year period for each asset class based on the expected long-term rate of return of the underlying assets.

We consider various factors in developing the estimates for the expected, long-term rates of return on plan assets. These factors include the projected, long-term rates of returns on the various types of assets in which the plans invest, as
well as historical returns. In general, investment allocations are determined by each plan’s trustees and/or investment committees. The objectives of the plans’ investment policies are to (i) maximize returns while preserving capital; (ii) provide returns sufficient to meet the current and long-term obligations of the plan as the obligations become due; and (iii) maintain a diversified portfolio of assets so as to reduce the risk associated with having a disproportionate amount of the plans’ total assets invested in any one type of asset, issuer or geography. None of our pension plans hold Jacobs common stock directly (although some plans may hold shares indirectly through investments in mutual funds). The plans’ weighted average asset allocations at September 27, 2024 and September 29, 2023 (the measurement dates used in valuing the plans’ assets and liabilities) were as follows:

Multiemployer Plans
In the U.S. and various other countries, we contribute to trusteed pension plans covering hourly and certain salaried employees under industry-wide agreements. Contributions are based on the hours worked by employees covered under these agreements and are charged to direct costs of contracts on a current basis. With respect to these multiemployer plans, the Company's liability to fund these plans is generally limited to the contributions we are required to make under collective bargaining agreements.
Based on our review of our multiemployer pension plans under the guidance provided in ASU 2011-09— Compensation-Retirement Benefits-Multiemployer Plans, we have concluded that none of the multiemployer pension plans into which we contribute are individually significant to our Consolidated Financial Statements.

Investment in Amentum Stock
As a result of the Separation Transaction on September 27, 2024, Jacobs held approximately 29 million of the outstanding shares of AMTM common stock initially recorded on a net book value basis under spin-off accounting rules.
Following the Merger and in accordance with the Escrow Agreement, Jacobs transferred 11 million shares of AMTM shares into escrow to be held and distributed between the parties to the Escrow Agreement based on terms and conditions set forth in the Merger Agreement, with final settlement of the shares between the parties (and associated financial statement impacts, if any) expected to be completed in fiscal 2025. The Company has indicated its intention to distribute shares held in escrow to Jacobs Shareholders’ post final settlement.
As of September 27, 2024, the Company's investment in AMTM shares (including shares held in escrow) was measured at fair value through net income as it is an investment in equity securities with a readily determinable fair value of approximately $749.5 million as of September 27, 2024. Additionally, fair value ("market") mark-to market gains of approximately $186.9 million were recorded in Miscellaneous income (expense), net during the fourth quarter of fiscal 2024 in association with the total AMTM share positions held. Further, as quoted market prices are available for these securities in an active market, the fair value measurement of the shares is categorized as a Level 1 input.
The Company intends to dispose of all of its final determined investment in AMTM shares within 12 months of the completion of the Separation and the Distribution.
Transition Services Agreement
Upon closing of the Separation, the Company entered into a Transition Services Agreement (the "TSA") with Amentum pursuant to which the Company, on an interim basis, provided various services to Amentum including corporate, information technology, and project services. The initial term of the TSA began immediately following the closing of the transaction on September 27, 2024 and expires in September 2025. Pursuant to the terms of the TSA, the Company will receive payments for the interim services and no services were provided under the TSA for the year ended September 27, 2024.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]  
PA Consulting Redeemable Noncontrolling Interests PA Consulting Redeemable Noncontrolling Interests
In connection with the PA Consulting investment, the Company recorded redeemable noncontrolling interests which represents the noncontrolling interest holders' equity interests in the form of preferred and common shares of PA Consulting, with substantially all of the value associated with these interests allocable to the preferred shares. PA Consulting is accounted for as a consolidated subsidiary and as a separate operating segment.
During fiscal 2024, 2023, and 2022, the Company repurchased certain shares of the redeemable noncontrolling interest holders for $55.3 million, $92.9 million, and $46.1 million respectively, in cash and issued certain shares of redeemable noncontrolling interest holders for $19.8 million, $34.0 million, and $49.7 million, respectively. The difference between the cash purchase prices and the recorded book values of these repurchased and issued interests was recorded in the Company’s consolidated retained earnings. The Company held 70% and 69% of the outstanding ownership of PA Consulting as of September 27, 2024 and September 29, 2023, respectively.
During fiscal 2024 and 2023 the Company recognized approximately $2.6 million and $8.3 million, respectively, in redemption value adjustments associated with redeemable noncontrolling interests preference share repurchase and reissuance activities concluding in fourth quarter fiscal 2024 and 2023 that were recorded as an increase in consolidated retained earnings and a $0.02 and $0.07, increase in earnings per share, the results of which had no impact on the Company’s overall results of operations, financial position or cash flows. See Note 4- Earnings Per Share and Certain Related Information.
During fiscal 2024 there was a $0.10 charge to earnings per share resulting from adjustments to the redeemable noncontrolling interests to reflect the excess of redemption values over fair values of the B common shares component of the redeemable equity with an offsetting reduction to Jacobs' retained earnings. These changes had no impact on the Company’s overall results of operations, financial position or cash flows. See Note 4- Earnings Per Share and Certain Related Information.

Other Business Combinations
StreetLight Data, Inc.
On February 4, 2022, the Company acquired StreetLight Data, Inc. ("StreetLight"). StreetLight is a pioneer of mobility analytics who uses its data and machine learning resources to shed light on mobility and enable users to solve complex transportation problems. The Company paid total base consideration of approximately $190.8 million in cash and issued $0.9 million in equity and $5.2 million in in-the-money stock options to the former owners of StreetLight. The Company also paid off StreetLight's debt of approximately $1.0 million simultaneously with the consummation of the acquisition.

Goodwill recognized resulted from a substantial assembled workforce, which does not qualify for separate recognition, as well as expected future synergies from combining operations. None of the goodwill recognized was deductible for tax purposes. The Company completed its final assessment of the fair values of StreetLight's assets acquired and liabilities assumed. Since the initial preliminary estimates reported in the second quarter of fiscal 2022, the Company updated certain amounts reflected in the preliminary purchase price allocation, as summarized in the fair values of StreetLight's assets acquired and liabilities assumed as of the acquisition date set forth above, the majority of which related to reclassifications between goodwill and intangibles and for deferred taxes.
Identifiable intangibles are technology, data and customer relationships, contracts and backlog and have estimated lives of 5, 4 and 9 years, respectively.

Other Business Combinations PA Consulting Redeemable Noncontrolling Interests
In connection with the PA Consulting investment, the Company recorded redeemable noncontrolling interests which represents the noncontrolling interest holders' equity interests in the form of preferred and common shares of PA Consulting, with substantially all of the value associated with these interests allocable to the preferred shares. PA Consulting is accounted for as a consolidated subsidiary and as a separate operating segment.
During fiscal 2024, 2023, and 2022, the Company repurchased certain shares of the redeemable noncontrolling interest holders for $55.3 million, $92.9 million, and $46.1 million respectively, in cash and issued certain shares of redeemable noncontrolling interest holders for $19.8 million, $34.0 million, and $49.7 million, respectively. The difference between the cash purchase prices and the recorded book values of these repurchased and issued interests was recorded in the Company’s consolidated retained earnings. The Company held 70% and 69% of the outstanding ownership of PA Consulting as of September 27, 2024 and September 29, 2023, respectively.
During fiscal 2024 and 2023 the Company recognized approximately $2.6 million and $8.3 million, respectively, in redemption value adjustments associated with redeemable noncontrolling interests preference share repurchase and reissuance activities concluding in fourth quarter fiscal 2024 and 2023 that were recorded as an increase in consolidated retained earnings and a $0.02 and $0.07, increase in earnings per share, the results of which had no impact on the Company’s overall results of operations, financial position or cash flows. See Note 4- Earnings Per Share and Certain Related Information.
During fiscal 2024 there was a $0.10 charge to earnings per share resulting from adjustments to the redeemable noncontrolling interests to reflect the excess of redemption values over fair values of the B common shares component of the redeemable equity with an offsetting reduction to Jacobs' retained earnings. These changes had no impact on the Company’s overall results of operations, financial position or cash flows. See Note 4- Earnings Per Share and Certain Related Information.

Restructuring and Other Charges Restructuring and Other Charges
During fiscal 2023, the Company implemented restructuring and separation initiatives relating to the Separation Transaction which are expected to continue through fiscal 2025. Restructuring initiatives were also implemented during fiscal 2023 relating to our investment in PA Consulting, which are expected to be substantially completed in early fiscal 2025, and the DVS segment reorganization, which is substantially completed. While restructuring activities for each of these programs are comprised mainly of employee termination costs, the separation activities and costs are primarily related to the engagement of outside services, dedicated internal personnel and other related costs dedicated to the Company's Separation Transaction.

During fiscal 2022, the Company implemented certain restructuring and integration initiatives relating to the acquisitions of (i) BlackLynx, Inc. (“BlackLynx”) in November 2021, and (ii) StreetLight Data, Inc. (“StreetLight”) in February 2022. Also, during fiscal 2022 and continuing into fiscal 2023, the Company implemented further real estate rescaling
efforts that were associated with its fiscal 2020 transformation program relating to real estate and other staffing initiatives. These initiatives are substantially completed.
As part of the Company's acquisition of CH2M Hill Companies, Ltd. ("CH2M") during fiscal 2018, the Company implemented certain restructuring plans that were comprised mainly of severance and lease abandonment programs as well as integration activities involving the engagement of professional services and internal personnel dedicated to the Company's integration management efforts.

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies and Derivative Financial Instruments Commitments and Contingencies and Derivative Financial Instruments
Derivative Financial Instruments
The Company is exposed to interest rate risk under its variable rate borrowings and additionally, due to the nature of the Company's international operations, we are at times exposed to foreign currency risk. As such, we sometimes enter into foreign exchange hedging contracts and interest rate hedging contracts in order to limit our exposure to fluctuating foreign currencies and interest rates.
During fiscal 2022, the Company entered into two treasury lock agreements which had a total notional value of $500 million to manage its interest rate exposure to the anticipated issuance of fixed rate debt before December 2023. On February 13, 2023, the Company settled these treasury lock agreements and issued the 5.90% Bonds in the aggregate principal amount of $500 million, which resulted in the receipt of cash and a pre-tax gain of $37.4 million, which is being amortized to interest expense and recognized over the term of the 5.90% Bonds. See Note 9- Borrowings for further discussion relating to the terms of the 5.90% Bonds. The unrealized net gain on these instruments was $23.6 million and $26.5 million, net of tax, and is included in accumulated other comprehensive income as of September 27, 2024 and September 29, 2023, respectively.
In fiscal 2020 we entered into interest rate swap agreements to manage the interest rate exposure on our variable rate loans. By entering into the swap agreements, the Company converted the LIBOR and SONIA rate based liabilities into fixed rate liabilities, for periods ranging from five to ten years.

During the fourth quarter of fiscal 2024, in connection with the Separation Transaction, the Company terminated two interest rate swaps with an aggregate notional value of $554.7 million for a realized a gain of $35.2 million. This realized gain previously recorded as a component of accumulated other comprehensive income was recognized in miscellaneous income (expense) in the current period as the related interest payments are no longer expected to occur. As of September 27, 2024, the Company has one outstanding instrument with a notional value of $200.0 million.

The fair value of the interest rate swaps at September 27, 2024 and September 29, 2023 was $23.0 million and $102.6 million, respectively, included within miscellaneous other assets on the consolidated balance. The unrealized net gain on these interest rate swaps as of September 27, 2024 and September 29, 2023 was $17.4 million and $77.2 million, respectively, net of tax, and was included in accumulated other comprehensive income.

Additionally, in fiscal 2020, we entered into a cross-currency swap agreement with a notional value of $127.8 million to manage the interest rate and foreign currency exposure on our USD borrowings by a European subsidiary. By entering into the cross currency swap, the Company converted the LIBOR rate based borrowing in USD to a fixed rate Euro liability for three and a half years. During the fourth quarter of fiscal 2023, the Company paid down the borrowings hedged by the cross currency swap and settled the cross currency swap agreement.

During fiscal 2023, the aggregate liability amounts denominated in U.S. dollars transitioned from underlying LIBOR benchmarked rates to the SOFR and the terms of the swaps were amended accordingly. The swaps were designated as cash-flow hedges in accordance with ASC 815, Derivatives and Hedging.
Additionally, the Company held foreign exchange forward contracts in currencies that support our operations, including British Pound, Australian Dollar and other currencies, with notional values of $827.3 million at September 27, 2024 and $857.7 million at September 29, 2023. The length of these contracts currently ranges from one to twelve months. The fair value of the foreign exchange contracts at September 27, 2024 was $15.3 million, of which $15.8 million is included within current assets and $(0.5) million is included within current liabilities on the consolidated balance sheet as of September 27, 2024. The fair value of the contracts as of September 29, 2023 was $9.5 million, of which $16.1 million is included within current assets and $(6.6) million is included within current liabilities on the consolidated balance sheet as of September 29, 2023. Associated income statement impacts are included in miscellaneous income (expense) in the consolidated statements of earnings for both periods.
The fair value measurements of these derivatives are being made using Level 2 inputs under ASC 820, Fair Value Measurement, as the measurements are based on observable inputs other than quoted prices in active markets. We are exposed to risk from credit-related losses resulting from nonperformance by counterparties to our financial instruments. We perform credit evaluations of our counterparties under forward exchange and interest rate contracts and expect all counterparties to meet their obligations. We have not experienced credit losses from our counterparties.
Letters of Credit
At September 27, 2024, the Company had issued and outstanding approximately $306.2 million in LOCs and $2.3 billion in surety bonds. Of the outstanding LOC amount, $0.5 million has been issued under the Revolving Credit Facility and $305.7 million are issued under separate, committed and uncommitted letter-of-credit facilities.

Contractual Guarantees, Litigation, Investigations, and Insurance [Abstract]  
Contractual Guarantees Litigation Investigations And Insurance Contractual Guarantees, Litigation, Investigations and Insurance
In the normal course of business, we make contractual commitments (some of which are supported by separate guarantees) and on occasion we are a party in a litigation or arbitration proceeding. The litigation or arbitration in which we are involved primarily includes personal injury claims, professional liability claims and breach of contract claims. Where we provide a separate guarantee, it is strictly in support of the underlying contractual commitment. Guarantees take various forms including surety bonds required by law, or standby letters of credit ("LOC" and also referred to as “bank guarantees”) or corporate guarantees given to induce a party to enter into a contract with a subsidiary. Standby LOCs are also used as security for advance payments or in various other transactions. The guarantees have various expiration dates ranging from an arbitrary date to completion of our work (e.g., engineering only) to completion of the overall project. See Note 18- Commitments and Contingencies and Derivative Financial Instruments for more information surrounding LOCs and surety bonds.
We maintain insurance coverage for most insurable aspects of our business and operations. Our insurance programs have varying coverage limits depending upon the type of insurance and include certain conditions and exclusions which insurance companies may raise in response to any claim that is asserted by or against the Company. We have also elected to retain a portion of certain losses, claims and liabilities that occur through the use of various deductibles, limits, and retentions under our insurance programs and utilize a number of internal financing mechanisms for these self-insurance arrangements, including the operation of certain captive insurance entities. As a result, we may be subject to a future liability for which we are only partially insured or completely uninsured. We intend to mitigate any such future liability by continuing to exercise prudent business judgment in negotiating the terms and conditions of the contracts which the Company enters with its clients. Our insurers are also subject to business risk and, as a result, one or more of them may be unable to fulfill their insurance obligations due to insolvency or otherwise.
Additionally, as a contractor providing services to the U.S. federal government, we are subject to many types of audits, investigations and claims by, or on behalf of, the government including with respect to contract performance, pricing, cost allocations, procurement practices, labor practices and socioeconomic obligations. Furthermore, our income, franchise and similar tax returns and filings are also subject to audit and investigation by the Internal Revenue Service, most states within the United States, as well as by various government agencies representing jurisdictions outside the United States.
Our Consolidated Balance Sheets include amounts representing our probable estimated liability relating to such claims, guarantees, litigation, audits and investigations. We perform an analysis to determine the level of reserves to establish for insurance-related claims that are known and have been asserted against us, as well as for insurance-related claims that are believed to have been incurred based on actuarial analysis but have not yet been reported to our claims administrators as of the respective balance sheet dates. We include any adjustments to such insurance reserves in our
consolidated results of operations. Insurance recoveries are recorded as assets if recovery is probable and estimated liabilities are not reduced by expected insurance recoveries.
The Company believes, after consultation with counsel, that such guarantees, litigation, U.S. government contract-related audits, investigations and claims and income tax audits and investigations should not have a material adverse effect on our consolidated financial statements, beyond amounts currently accrued.
In 2012, CH2M HILL Australia PTY Limited, a subsidiary of CH2M, entered into a 50/50 integrated joint venture with Australian construction contractor UGL Infrastructure Pty Limited. The joint venture entered into a Consortium Agreement with General Electric and GE Electrical International Inc. The Consortium was awarded a subcontract by JKC Australia LNG Pty Limited ("JKC") for the engineering, procurement, construction and commissioning of a 360 MW Combined Cycle Power Plant for INPEX Operations Australia Pty Limited at Blaydin Point, Darwin, NT, Australia (the "Legacy CH2M Matter"). The subcontract was terminated in January 2017. In or around August 2017, the Consortium commenced an arbitration. On April 12, 2022, JKC and the Consortium entered into a confidential deed of settlement (“Settlement Agreement”). Under the terms of the Settlement Agreement, CH2M, as guarantor of CH2M Australia PTY Limited’s obligations with respect to the subcontract with JKC, made a cash payment to JKC in April 2022 of AUD 640 million (or approximately $475 million using mid-April 2022 exchange rates). As a result of the settlement agreement, additional pre-tax charges of $91.3 million were recorded during the year ended September 29, 2022 for this matter (over amounts previously reserved and reported in long-term Other Deferred Liabilities in the Company's Consolidated Balance Sheet). The Settlement Agreement provided for a release of claims between JKC and each member of the Consortium, and in connection with this agreement the members of the Consortium also waived all claims against each other and their respective parent guarantors relating to the project.
During the fourth quarter of fiscal 2022, the Company recorded a receivable for certain expected third-party recoveries equal to approximately $27 million before tax. The Company received the payment during fiscal 2023.

Segment Information Segment Information
Prior to the Separation Transaction, the Company's four operating segments were comprised of its two global lines of business ("LOBs"): Critical Mission Solutions ("CMS") and People, Places Solutions ("P&PS"), its business unit Divergent Solutions ("DVS") and its majority investment in PA Consulting. Subsequent to the Separation Transaction, the SpinCo businesses are now presented as discontinued operations for all periods and therefore not reflected in the segment disclosures below. For further information, refer to Note 14- Discontinued Operations. In addition, the Company reorganized its operating and reporting structure whereby results for the formerly known P&PS operating segment and the portion of the DVS business and other supporting corporate expenses not conveying with the Disposal Group are now reported together, as Infrastructure and Advanced Facilities ("I&AF").
The Company’s Chief Executive Officer is the (“CODM”) and evaluates the performance of each of these segments and make appropriate resource allocations among each of the segments. For purposes of the Company’s goodwill impairment testing, it has been determined that the Company’s operating segments are also its reporting units based on management’s conclusion that the components comprising each of its operating segments share similar economic characteristics and meet the aggregation criteria for reporting units in accordance with ASC 350, Intangibles-Goodwill and Other.
Financial information for each segment is reviewed by the CODM to assess performance and make decisions regarding the allocation of resources. The CODM evaluates the operating performance of our operating segments using segment operating profit. The Company incurs certain SG&A that relate to its business as a whole which are not allocated to the segments.
The following tables present total revenues and segment operating profit from continuing operations for each reportable segment (in thousands) and includes a reconciliation of segment operating profit to total U.S. GAAP operating profit by including Restructuring and other charges (as defined in Note 17-Restructuring and Other Charges) and

Revenue Accounting For Contracts
Revenue Accounting for Contracts
Engineering, Procurement & Construction Contracts, Service Contracts and Software Contracts
The Company recognizes engineering, procurement, and construction contract revenue over time, as performance obligations are satisfied, due to the continuous transfer of control to the customer in accordance with ASC Topic 606, Revenue from Contracts with Customers. Contracts which include engineering, procurement and construction services are generally accounted for as a single deliverable (a single performance obligation) and are no longer segmented between types of services. In some instances, the Company’s services associated with a construction activity are limited to specific tasks such as customer support, consulting or supervisory services. In these instances, the services are typically identified as separate performance obligations.
The Company recognizes revenue using the percentage-of-completion method, based primarily on contract costs incurred to date compared to total estimated contract costs. The percentage-of-completion method (an input method) is the most representative depiction of the Company’s performance because it directly measures the value of the services transferred to the customer. Subcontractor materials, labor and equipment and, in certain cases, customer-furnished materials and labor and equipment are included in revenue and cost of revenue when management believes that the company is acting as a principal rather than as an agent (e.g., the company integrates the materials, labor and equipment into the deliverables promised to the customer or is otherwise primarily responsible for fulfillment and acceptability of the materials, labor and/or equipment). The Company recognizes revenue, but not profit, on certain uninstalled materials that are not specifically produced, fabricated, or constructed for a project. Changes to total estimated contract cost or losses, if any, are recognized in the period in which they are determined as assessed at the contract level. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. Project mobilization costs are generally charged to project costs as incurred when they are an integrated part of the performance obligation being transferred to the client. Under the typical payment terms of our engineering, procurement and construction contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms at periodic intervals (e.g., biweekly or monthly) and customer payments are typically due within 30 to 60 days of billing, depending on the contract.
For service contracts, the Company recognizes revenue over time using the cost-to-cost percentage-of-completion method. Service contracts that include multiple performance obligations are segmented between types of services. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using an estimate of the stand-alone selling price of each distinct service in the contract. In some instances where the Company is standing ready to provide services, the Company recognizes revenue ratably over the service period. Under the typical payment terms of our service contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, and customer payments are typically due within 30 to 60 days of billing, depending on the contract.
Revenue for certain contracts related to the sale of software licenses is recognized at a point in time, typically at the time of delivery, in accordance with ASC 606. The software license sale will be treated as a performance obligation separate and distinct from any related service and maintenance.
Direct costs of contracts include all costs incurred in connection with and directly for the benefit of client contracts, including depreciation and amortization relating to assets used in providing the services required by the related projects. The level of direct costs of contracts may fluctuate between reporting periods due to a variety of factors, including the amount of pass-through costs we incur during a period. On those projects where we are acting as principal for subcontract labor or third-party materials and equipment, we reflect the amounts of such items in both revenues and costs (and we refer to such costs as “pass-through costs”).
    Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable, and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above have been satisfied.
Variable Consideration
The nature of the Company’s contracts gives rise to several types of variable consideration, including claims and unpriced change orders; awards and incentive fees; and liquidated damages and penalties. The Company recognizes revenue for variable consideration when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company estimates the amount of revenue to be recognized on variable consideration using the expected value (i.e., the sum of a probability-weighted amount) or the most likely amount method, whichever is expected to better predict the amount. Factors considered in determining whether revenue associated with claims (including change orders in dispute and unapproved change orders in regard to both scope and price) should be recognized include the following: (a) the contract or other evidence provides a legal basis for the claim, (b) additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in the company’s performance, (c) claim-related costs are identifiable and considered reasonable in view of the work performed, and (d) evidence supporting the claim is objective and verifiable. If the requirements for recognizing revenue for claims or unapproved change orders are met, revenue is recorded only when the costs associated with the claims or unapproved change orders have been incurred and only up to the amount of consideration that is probable of not being reversed.
The Company generally provides limited warranties for work performed under its engineering and construction contracts. The warranty periods typically extend for a limited duration following substantial completion of the Company’s work on the project. Historically, warranty claims have not resulted in material costs incurred for which the Company was not compensated for by the customer.
See Note 3- Revenue Accounting for Contracts for further discussion.
Joint Ventures and VIEs
As is common to the industry, we execute certain contracts jointly with third parties through various forms of joint ventures. Although the joint ventures own and hold the contracts with the clients, the services required by the contracts are typically performed by us and our joint venture partners, or by other subcontractors under subcontracting agreements with the joint ventures. Many of these joint ventures are formed for a specific project. The assets of our joint ventures generally consist almost entirely of cash and receivables (representing amounts due from clients), and the liabilities of our joint ventures generally consist almost entirely of amounts due to the joint venture partners (for services provided by the partners to the joint ventures under their individual subcontracts) and other subcontractors. In general, at any given time, the equity of our joint ventures represents the undistributed profits earned on contracts the joint ventures hold with clients. Very few of our joint ventures have employees or third-party debt or credit facilities. The debt held by the joint ventures is non-recourse to the general credit of Jacobs.
The assets of a joint venture are available for use for the obligations of the particular joint venture and not for general operations of the Company. Our risk of loss on these arrangements is usually shared with our partners. The liability of each partner is usually joint and several, which means that each partner may become liable for the entire risk of loss on the project. Furthermore, on some of our projects, the Company has granted guarantees which may encumber both our contracting subsidiary company and the Company for the entire risk of loss on the project. The Company is unable to estimate the maximum potential amount of future payments that we could be required to make under outstanding performance guarantees related to joint venture projects due to a number of factors, including but not limited to, the nature and extent of any contractual defaults by our joint venture partners, resource availability, potential performance delays caused by the defaults, the location of the projects, and the terms of the related contracts. See Note 19 - Contractual Guarantees, Litigation, Investigations and Insurance for further discussion.
Most of the joint ventures are deemed to be variable interest entities (“VIE”) because they lack sufficient equity to finance the activities of the joint venture. The Company uses a qualitative approach to determine if the Company is the primary beneficiary of the VIE, which considers factors that indicate a party has the power to direct the activities that most significantly impact the joint venture’s economic performance. These factors include the composition of the governing board, how board decisions are approved, the powers granted to the operational manager(s) and partner that holds that position(s), and to a certain extent, the partner’s economic interest in the joint venture. The Company analyzes each joint venture initially to determine if it should be consolidated or unconsolidated.
Consolidated if the Company is the primary beneficiary of a VIE or holds the majority of voting interests of a non-VIE (and no significant participative rights are available to the other partners).
Unconsolidated if the Company is not the primary beneficiary of a VIE or does not hold the majority of voting interest of a non-VIE.
Our unconsolidated joint ventures (including equity method investments) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable, and impairment losses are recognized for such investments if there is a decline in fair value below carrying value that is considered to be other-than-temporary.
Fair Value Measurements
Fair Value Measurements
Certain amounts included in the accompanying consolidated financial statements are presented at “fair value.” Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants as of the date fair value is determined (the “measurement date”). When determining fair value, we consider the principal or most advantageous market in which we would transact, and we consider only those assumptions we believe a typical market participant would consider when pricing an asset or liability. In measuring fair value, we use the following inputs in the order of priority indicated:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than quoted prices in active markets included in Level 1, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions (e.g., less active markets); and (iii) model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data for substantially the full term of the asset or liability.
Level 3 - Unobservable inputs to the valuation methodology that are significant to the fair value measurement.
The net carrying amounts of cash and cash equivalents, trade receivables and payables and short-term debt approximate fair value due to the short-term nature of these instruments. See Note 9- Borrowings for a discussion of the fair value of long-term debt.
Certain other assets and liabilities, such as forward contracts and interest rate swap agreements we purchased as cash-flow hedges discussed in Note 18- Commitments and Contingencies and Derivative Financial Instruments and the Company's investment in Amentum ordinary shares discussed in Note 14- Discontinued Operations are required to be carried in our Consolidated Financial Statements at Fair Value.
The fair value of the Company’s reporting units (used for purposes of determining whether there is an impairment of the carrying value of goodwill) is determined using an income and market approach. Both approaches require us to make certain estimates and judgments. Under the income approach, fair value is determined by using the discounted cash flows of our reporting units. Under the market approach, the fair values of our reporting units are determined by reference to guideline companies that are reasonably comparable to our reporting units; the fair values are estimated based on the valuation multiples of earnings before taxes, interest, depreciation and amortization associated with the guideline companies. In assessing whether the carrying value of goodwill has been impaired, we utilize the results of both valuation techniques and consider the range of fair values indicated.
With respect to equity-based compensation (i.e., share-based payments), we estimate the fair value of stock options granted to employees and directors using the Black-Scholes option-pricing model. Like all option-pricing models, the Black-Scholes model requires the use of subjective assumptions including (i) the expected volatility of the market price
of the underlying stock, and (ii) the expected term of the award, among others. Accordingly, changes in assumptions and any subsequent adjustments to those assumptions can cause different fair values to be assigned to our future stock option awards. For restricted stock awards (including restricted stock units) containing service and performance conditions, fair value is based on the closing stock price on the date of grant, adjusted for the expected level of achievement for any performance conditions.
The fair values of the assets owned by the various pension plans that the Company sponsors are determined based on the type of asset, consistent with U.S. GAAP. Equity securities are valued by using market observable data such as quoted prices. Publicly traded corporate equity securities are valued at the last reported sale price on the last business day of the year. Securities not traded on the last business day are valued at the last reported bid price. Fixed income investment funds categorized as Level 2 are valued by the trustee using pricing models that use verifiable observable market data (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers, or quoted prices of securities with similar characteristics. Real estate consists primarily of common or collective trusts, with underlying investments in real estate. These investments are valued using the best information available, including quoted market price, market prices for similar assets when available, internal cash flow estimates discounted at an appropriate interest rate, or independent appraisals, as appropriate. Management values insurance contracts and hedge funds using actuarial assumptions and certain values reported by fund managers.
Fair value measurements relating to our business combinations are made primarily using Level 3 inputs including discounted cash flow and to the extent applicable, Monte Carlo simulation techniques. Fair value for the identified intangible assets is generally estimated using inputs primarily for the income approach using the multiple period excess earnings method and the relief from royalties method. The significant assumptions used in estimating fair value include (i) revenue projections of the business, including profitability, (ii) attrition rates and (iii) the estimated discount rate that reflects the level of risk associated with receiving future cash flows. Other personal property assets, such as furniture, fixtures and equipment, are valued using the cost approach, which is based on replacement or reproduction costs of the asset less depreciation. The fair value of the contingent consideration is estimated using a Monte Carlo simulation and the significant assumptions used include projections of revenues and probabilities of meeting those projections. Key inputs to the valuation of the noncontrolling interests include projected cash flows and the expected volatility associated with those cash flows.
The fair values for the asset groups relating to the impairment assessment of long-lived assets (see Note 10- Leases) were estimated primarily using discounted cash flow models (income approach) with Level 3 inputs. The significant assumptions used in estimating fair value include the expected downtime prior to the commencement of future subleases, projected sublease income over the remaining lease periods and discount rates that reflects the level of risk associated with receiving future cash flows.
The methodologies described above and elsewhere in these Notes to Consolidated Financial Statements may produce a fair value measure that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes Level 3 valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement.
Cash Equivalents
Cash Equivalents
We consider all highly liquid investments with original maturities of less than three months to be cash equivalents.
Receivables, Contract Assets and Contract Liabilities
Receivables, Contract Assets and Contract Liabilities
Receivables include amounts billed, net and unbilled receivables. Amounts billed, net consist of amounts invoiced to clients in accordance with the terms of our client contracts and are shown net of an allowance for expected credit losses. We anticipate that substantially all of such billed amounts will be collected over the next twelve months.
Unbilled receivables and other, which represent an unconditional right to payment subject only to the passage of time in connection with our client contracts, are reclassified to amounts billed when they are billed under the terms of the contract. We anticipate that substantially all of such unbilled amounts will be billed and collected over the next twelve months.
Contract assets represent unbilled amounts where the right to payment is subject to more than merely the passage of time and includes performance-based incentives and services provided ahead of agreed contractual milestones. Contract assets are transferred to unbilled receivables when the right to consideration becomes unconditional and are transferred to amounts billed upon invoicing.
Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. We anticipate that substantially all such amounts will be earned over the next twelve months.
Property, Equipment and Improvements
Property, Equipment, and Improvements
Property, equipment and improvements are carried at cost, and are shown net of accumulated depreciation and amortization in the accompanying Consolidated Balance Sheets. Depreciation and amortization are computed primarily by using the straight-line method over the estimated useful lives of the assets. The cost of leasehold improvements is amortized using the straight-line method over the lesser of the estimated useful life of the asset or the remaining term of the related lease. Estimated useful lives range from 20 to 40 years for buildings, from 3 to 10 years for equipment and from 1 to 14 years for leasehold improvements.
Goodwill and Other Intangible Assets
Goodwill and Other Intangible Assets
Goodwill represents the excess of the cost of an acquired business over the fair value of the net tangible and intangible assets acquired. Goodwill and intangible assets with indefinite lives are not amortized; instead, on an annual basis we test goodwill and intangible assets with indefinite lives for possible impairment. Intangible assets with finite lives are amortized on a straight-line basis over the useful lives of those assets.
For purposes of impairment testing, goodwill is assigned to the applicable reporting units based on the current reporting structure. We have determined that our operating segments are also our reporting units based on management’s conclusion that the components comprising each of our operating segments share similar economic characteristics and meet the aggregation criteria in accordance with ASC 350.
We perform our annual goodwill impairment assessment as of the first day of the fourth fiscal quarter each year. We begin with the qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the quantitative assessment described below. If it is determined through the evaluation of events or circumstances that the carrying value may not be recoverable, the Company then compares the fair value of the related reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized. For the 2024 fiscal year, we performed a quantitative impairment test of the historical DVS reporting unit as of the beginning of the fourth quarter and determined that the fair value of the reporting unit exceeded its carrying value. For the remaining reporting units, we determined that the fair values significantly exceeded their carrying values and an analysis beyond the qualitative level was not considered necessary.
Impairment of Long-Lived Assets
Impairment of Long-Lived Assets
Our long-lived assets other than goodwill principally consist of right-of-use (ROU) lease assets, property, equipment and improvements, and finite-lived intangible assets. These long-lived assets are evaluated for impairment for each of our asset groups in accordance with ASC 360 by first identifying whether indicators of impairment exist. If such indicators are present, we assess long-lived asset groups for recoverability based on estimated future undiscounted cash flows. For asset groups where the recoverability test fails, the fair value of each asset group is then estimated and compared to its carrying amount. An impairment loss is recognized for the amount by which an asset group’s carrying value exceeds its fair value.
Foreign Currencies
Foreign Currencies
In preparing our Consolidated Financial Statements, it is necessary to translate the financial statements of our subsidiaries operating outside the U.S., which are denominated in currencies other than the U.S. dollar, into the U.S. dollar. In accordance with U.S. GAAP, revenues and expenses of operations outside the U.S. are translated into U.S. dollars using weighted-average exchange rates for the applicable periods being translated while the assets and liabilities of operations outside the U.S. are generally translated into U.S. dollars using period-end exchange rates. The net effect of foreign currency translation adjustments is included in stockholders’ equity as a component of accumulated other comprehensive income (loss) in the accompanying Consolidated Balance Sheets.
Share-based Payments
Share-Based Payments
We measure the value of services received from employees and directors in exchange for an award of an equity instrument based on the grant-date fair value of the award. The fair value is recognized as a non-cash cost on a straight-line basis over the period the individual provides services, which is typically the vesting period of the award with the exception of awards containing an internal performance measure, such as Earnings Per Share growth and Return on Invested Capital, which is recognized on a straight-line basis over the vesting period subject to the probability of meeting the performance requirements and adjusted for the number of shares expected to be earned. The cost of these awards is recorded in selling, general and administrative expense in the accompanying Consolidated Statements of Earnings.
Concentration of Credit Risk
Concentrations of Credit Risk
Our cash balances and cash equivalents are maintained in accounts held by major banks and financial institutions located in North America, South America, Europe, the Middle East, India, Australia, Africa and Asia. In the normal course of business, and consistent with industry practices, we grant credit to our clients without requiring collateral. Concentrations of credit risk is the risk that, if we extend a significant amount of credit to clients in a specific geographic area or industry, we may experience disproportionately high levels of default if those clients are adversely affected by factors particular to their geographic area or industry. Concentrations of credit risk relative to trade receivables are limited due to our diverse client base, which includes the U.S. federal government and multi-national corporations operating in a broad range of industries and geographic areas. Additionally, in order to mitigate credit risk, we continually evaluate the credit worthiness of our major commercial clients.
Leases
Leases
The Company accounts for its leases in accordance with ASC 842, Leases ("ASC 842"). ASC 842 requires lessees to recognize assets and liabilities for most leases. The Company determines if an arrangement is a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of an identified asset for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract, and (2) the customer has the right to control the use of the identified asset. Lessees are required to classify leases as either finance or operating leases. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease.
The Company’s right-of use assets and lease liabilities relate to real estate, project assets used in connection with long-term construction contracts, IT assets and vehicles. The Company’s leases have remaining lease terms of less than one year to nineteen years. The Company’s lease obligations are primarily for the use of office space and are primarily operating leases. Certain of the Company’s leases contain renewal, extension, or termination options. The Company assesses each option on an individual basis and will only include options reasonably certain of exercise in the lease term. The Company generally considers the base term to be the term provided in the contract. None of the Company’s lease agreements contain material options to purchase the leased property, material residual value guarantees, or material restrictions or covenants.
Long-term project asset and vehicle leases (leases with terms greater than twelve months), along with all real estate and IT asset leases, are recorded on the consolidated balance sheet at the present value of the minimum lease payments not yet paid. Because the Company primarily acts as a lessee and the rates implicit in its leases are not readily determinable, the Company generally uses its incremental borrowing rate on the lease commencement date to calculate the present value of future lease payments. Certain leases include payments that are based solely on an index or rate. These variable lease payments are included in the calculation of the ROU asset and lease liability and are initially measured using the index or rate at the lease commencement date. Other variable lease payments, such as payments based on use and for property taxes, insurance, or common area maintenance that are based on actual assessments are excluded from the ROU asset and lease liability and are expensed as incurred. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any deferred rent, lease prepayments and initial direct costs of obtaining the lease, such as commissions.
Certain lease contracts contain non-lease components such as maintenance and utilities. The Company has made an accounting policy election, as allowed under ASC 842-10-15-37 and discussed above, to capitalize both the lease component and non-lease components of its contracts as a single lease component for all of its right-of-use assets.
Short-term project asset and vehicle leases (project asset and vehicle leases with an initial term of twelve months or less or leases that are cancellable by the lessee and lessor without significant penalties) are not recorded on the consolidated balance sheet and are expensed on a straight-line basis over the lease term. The majority of the Company’s short-term leases relate to equipment used on construction projects. These leases are entered into at agreed upon hourly, daily, weekly or monthly rental rates for an unspecified duration and typically have a termination for convenience provision. Such equipment leases are considered short-term in nature unless it is reasonably certain that the equipment will be leased for a term greater than twelve months.
Pensions
Pensions
We use certain assumptions and estimates in order to calculate periodic pension cost and the value of the assets and liabilities of our pension plans. These assumptions involve discount rates, investment returns, and projected salary increases, among others. Changes in the actuarial assumptions may have a material effect on the plans’ liabilities and the projected pension expense.
We use a corridor approach to amortize actuarial gains and losses. Under this approach, net gains or losses in excess of ten percent of the larger of the pension benefit obligation or the market-related value of the assets are amortized on a straight-line basis. The period of amortization is the average remaining service of active participants who are expected to receive benefits under certain plans and the average remaining future lifetime of plan participants for certain plans.
We measure our defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end, which is September 27, 2024 as the alternative measurement date in accordance with FASB guidance ASU 2015-04, Compensation Retirement Benefit (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Asset. This guidance allows employers with fiscal year ends that do not coincide with a calendar month end to make an accounting policy election to measure defined benefit plan assets and obligations as of the end of the month closest to their fiscal year end.
Redeemable Noncontrolling Interests
Redeemable Noncontrolling Interests
In connection with the PA Consulting investment in March 2021, the Company recorded redeemable noncontrolling interests, representing the interest holders' 35% equity interest in the form of preferred and common shares of PA Consulting. The preferred shares are entitled to a cumulative annual compounding 12% dividend based on the outstanding preferred share subscription price. These noncontrolling interest holders have certain option rights to put the preferred and common share interests back to the Company at a value based on the fair value of PA Consulting (the redemption values). The primary inputs and assumptions impacting the fair value of PA Consulting include projections of revenue and earnings before interest, taxes, depreciation and amortization and discount rates applied thereto. Additionally, the Company has an option to call the interests for certain individual shareholders in certain circumstances. Because the interests are redeemable at the option of the holders and not solely within the control of the Company, the Company classified the interests in redeemable noncontrolling interests within its Consolidated Balance Sheet at their redemption values. The optional redemption features may become exercisable no earlier than five years from the March 2, 2021 closing date, or upon the occurrence of certain other events.
The Company has deemed these interests probable of becoming redeemable in the future and requiring their measurement at the greater of (i) the redemption amount that would be paid if settlement occurred at the balance sheet date, or (ii) the historical value resulting from the original acquisition date fair value plus the impact of any earnings or loss attribution amounts, including dividends. The fair value of the PA Consulting redeemable noncontrolling interest is determined using a combination of the income and market approaches. Under the income approach, fair value is determined by using the projected discounted cash flows of PA Consulting. Under the market approach, the fair value is determined by reference to guideline companies that are reasonably comparable to PA Consulting; the fair value is estimated based on the valuation multiples of earnings before interest, taxes, depreciation and amortization.
Further, to the extent redemption values exceed historical values of the interests, changes in redemption amounts are recognized as changes to redeemable noncontrolling interests with an offsetting change in consolidated retained earnings. Additionally, particular to the preference share and in certain circumstances the ordinary share components of redeemable noncontrolling interests, such changes in consolidated retained earnings could also be reflected as a corresponding adjustment to net earnings attributable to Jacobs for purposes of the calculation of consolidated earnings per share attributable to common shareholders.
Income Taxes
Income Taxes
We determine our consolidated income tax expense using the asset and liability method prescribed by U.S. GAAP. Under this method, deferred tax assets and liabilities are recognized for the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and income tax purposes. Such deferred tax assets and liabilities are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. If and when we determine that a deferred tax asset will not be realized for its full amount, we will recognize and record a valuation allowance with a corresponding charge to earnings. Judgment is required in determining our provision for income taxes. In the normal course of business, we may engage in numerous transactions every day for which the ultimate tax outcome (including the period in which the transaction will ultimately be included in taxable income or deducted as an expense) is uncertain. Additionally, we file income, franchise, gross receipts and similar tax returns in many jurisdictions. Our tax returns are subject to audit and investigation by the Internal Revenue Service, most states in the U.S., and by various government agencies representing many jurisdictions outside the U.S.
The Tax Cuts and Jobs Act of 2017 (the "Tax Act") contains a provision which subjects a U.S. parent of a foreign subsidiary to current U.S. tax on its global intangible low–taxed income (“GILTI”). The GILTI income is eligible for a deduction, which lowers the effective tax rate of GILTI to 10.5% for calendar years 2018 through 2025 and 13.125% after 2025. The Company will report the tax impact of GILTI as a period cost when incurred. Accordingly, the Company is not providing deferred taxes for basis differences expected to reverse as GILTI.
Contractual Guarantees, Litigation, Investigations and Insurance
Contractual Guarantees, Litigation, Investigations and Insurance
In the normal course of business, we are subject to certain contractual guarantees and litigation. We record in the Consolidated Balance Sheets amounts representing our estimated liability relating to such guarantees, litigation and insurance claims. Guarantees are accounted for in accordance with ASC 460-10, Guarantees, at fair value at the inception of the guarantee. We perform an analysis to determine the level of reserves to establish for both insurance-related claims that are known and have been asserted against us as well as for insurance-related claims that are believed to have been incurred based on actuarial analysis but have not yet been reported to our claims administrators as of the respective
balance sheet dates. We include any adjustments to such insurance reserves in our Consolidated Statements of Earnings. In addition, as a contractor providing services to various agencies of the U.S. federal government, we are subject to many levels of audits, investigations, and claims by, or on behalf of, the U.S. federal government with respect to contract performance, pricing, costs, cost allocations and procurement practices. We adjust revenues based upon the amounts we expect to realize considering the effects of any client audits or governmental investigations.
Business Combinations
Business Combinations
U.S. GAAP requires that the purchase price paid for business combinations accounted for using the acquisition method be allocated to the assets and liabilities acquired based on their respective fair values. The Company makes certain estimates and judgments relating to other assets and liabilities acquired as well as any identifiable intangible assets acquired.
Use of Estimates and Assumptions
Use of Estimates and Assumptions
The preparation of financial statements in conformity with U.S. GAAP requires us to employ estimates and make assumptions that affect the reported amounts of certain assets and liabilities; the revenues and expenses reported for the periods covered by the financial statements; and certain amounts disclosed in these Notes to the Consolidated Financial Statements. Although such estimates and assumptions are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available and past experience, actual results could differ significantly from those estimates and assumptions. Our estimates, judgments and assumptions are evaluated periodically and adjusted accordingly.

ASU 2023-09, Income Taxes, (Topic 740): Improvements to Income Tax Disclosures, provides qualitative and quantitative updates to the Company's effective income tax rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied prospectively; however, retrospective application is also permitted. ASU 2023-09 will be effective for the Company's annual fiscal 2026 period. The Company has identified and is implementing changes to processes and internal controls to meet the standard’s updated reporting and disclosure requirements.
ASU 2023-07, Segment Reporting, (Topic 280): Improvements to Reportable Segment Disclosures, 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 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and the amendments in this update are required to be applied on a retrospective basis. ASU 2023-07 will be effective for the Company's annual fiscal 2025 period. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
ASU 2023-06, Disclosure Improvements: Amendments - Codification Amendments in Response to the Disclosure Update and Simplification Initiative of the Securities and Exchange Commission ("SEC"). The Financial Accounting Standards Board issued the standard to introduce changes to US GAAP that originate in either SEC Regulation S-X or S-K, which are rules about the form and content of financial reports filed with the SEC. The provisions of the standard are contingent upon instances where the SEC removes the related disclosure provisions from Regulation S-X and S-K. The Company does not expect that the application of this standard will have a material impact on our consolidated financial statements and related disclosures.

Additionally, fiscal 2023 included approximately $15.0 million in net favorable impacts from cost reductions compared to the prior year period, which was associated mainly with net favorable impacts during first quarter from changes in employee benefit programs of $41.0 million offset by approximately $26.0 million in higher spend in company technology platforms and other personnel and corporate cost increases.
(2)
The years ended September 27, 2024, and September 29, 2023 include $163.4 million and $61.1 million respectively, in restructuring and other charges (mainly professional services and employee separation costs) primarily related to the Separation Transaction and $6.4 million and $14.3 million respectively, in restructuring and other charges relating to the Company's investment in PA Consulting (primarily employee separation costs). Included in the years ended September 29, 2023 and September 30, 2022 were $46.7 million and $76.1 million, respectively, in charges associated mainly with real estate impairments. Included in the year ended September 30, 2022 is $91.3 million pre-tax related to the final settlement of the Legacy CH2M Matter and net of previously recorded reserves and approximately $27 million in third party recoveries that was recorded as receivables reducing SG&A.
(3)
The year ended September 27, 2024 included $186.9 million in mark-to-market gains associated with our investment in Amentum stock in connection with the Separation Transaction and a $35.2 million realized gain on interest rate swaps settled during the fourth quarter of fiscal 2024.

The increase in net interest expense from fiscal 2022 to fiscal 2023 is due primarily to higher interest rates.
