Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	Note 1—Nature of Operations and Basis of Presentation Nature of Operations and Basis of Presentation Leidos Holdings, Inc. ("Leidos"), a Delaware corporation, is a holding company whose direct 100%-owned subsidiary and principal operating company is Leidos, Inc. Leidos is a FORTUNE 500® technology, engineering, and science company that provides services and solutions in the defense, intelligence, civil and health markets, both domestically and internationally. Leidos' customers include the U.S. Department of Defense ("DoD"), the U.S. Intelligence Community, the U.S. Department of Homeland Security, the Federal Aviation Administration, the Department of Veterans Affairs and many other U.S. civilian, state and local government agencies, foreign government agencies and commercial businesses. Unless indicated otherwise, references to "we," "us" and "our" refer collectively to Leidos Holdings, Inc. and its consolidated subsidiaries. We operate in three reportable segments: Defense Solutions, Civil and Health. Additionally, we separately present the unallocable costs associated with corporate functions as Corporate. We have an 88% controlling interest in Mission Support Alliance, LLC ("MSA"), a joint venture with Centerra Group, LLC, which includes 41% purchased from Jacobs Group, LLC on January 26, 2018. MSA’s contract ended on January 24, 2021. We also have a 53% controlling interest in Hanford Mission Integration Solutions, LLC ("HMIS"), the legal entity for the follow-on contract to MSA's contract and a joint venture with Centerra Group, LLC and Parsons Government Services, Inc. We consolidate the financial results for MSA and HMIS into our consolidated financial statements. The consolidated financial statements also include the balances of all voting interest entities in which Leidos has a controlling voting interest ("subsidiaries") and a variable interest entity ("VIE") in which Leidos is the primary beneficiary. The consolidated balances of the VIE are not material to the consolidated financial statements for the periods presented. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation. Effective July 3, 2021, certain contracts were reassigned from the Defense Solutions reportable segment to the Civil reportable segment. Impact on prior year segment results were determined to be immaterial and have not been recast to reflect this change. Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. We combined "Capital distributions to non-controlling interests" and "Capital contributions from non-controlling interests" into "Net capital (distributions to) contributions from non-controlling interests", "Collections on promissory notes" and "Bad debt expense and recoveries" into "Other" on the consolidated statements of cash flows.

Accounting Changes and Error Corrections [Abstract]
Accounting Standards	Note 2—Accounting Standards Accounting Standards Updates Adopted ASU 2021-08, Business Combinations (Topic 805) In October 2021, the FASB issued ASU 2021-08, which amends how contract assets and liabilities acquired in a business combination are measured. Current guidance requires contract assets and liabilities to be measured at fair value in accordance with ASC 805, Business Combinations. The amendments in this Update remove the requirement to measure contract assets and liabilities at fair value and instead require that they be recognized in accordance with ASC 606, Revenue from Contracts with Customers. We adopted the requirements of ASU 2021-08 using the prospective method effective the first day of fiscal 2022. For business combinations occurring after adoption, we measured contract assets and liabilities acquired in accordance ASC 606. Accounting Standards Updates Issued But Not Yet Adopted ASU 2020-04, ASU 2021-01, and ASU 2022-06 Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, which provides companies with optional expedients and exceptions to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. This update provides optional expedients for applying accounting guidance to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of the reference rate reform. The amendments in this update are effective for all entities as of March 2020 and can be adopted using a prospective approach no later than December 31, 2022. In January 2021, the FASB issued ASU 2021-01 which amends the scope of ASU 2020-04. The amendments in this update are elective and provide optional relief for entities with hedge accounting and contract modifications affected by the discounting transition through December 31, 2022. In December 2022, the FASB issued ASU 2022-06 which extends the deadline for application of ASU 2021-01 through December 31, 2024. Under this relief, entities may continue to account for contract modifications as a continuation of the existing contract and the continuation of the hedge accounting arrangement. We are currently evaluating the impacts of the reference rate reform. Except for our new $380 million term loan entered into on May 6, 2022 (see "Note 13—Debt"), we currently use the one-month LIBOR for which the rate publication will cease in June 2023.

- Definition

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 3—Summary of Significant Accounting Policies

Reporting Periods

Leidos' fiscal year ends on the Friday nearest the end of December. Fiscal 2022 ended December 30, 2022. Fiscal 2022, 2021 and 2020 each included 52 weeks.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Management evaluates these estimates and assumptions on an ongoing basis, including those relating to estimated profitability of long-term contracts, indirect billing rates, allowances for doubtful accounts, inventories, right-of-use ("ROU") assets and lease liabilities, fair value and impairment of intangible assets and goodwill, income taxes, pension benefits, stock-based compensation expense and contingencies. These estimates have been prepared by management on the basis of the most current and best available information; however, actual results could differ materially from those estimates.

Operating Cycle

Our operating cycle for long-term contracts may be greater than one year and is measured by the average time intervening between the inception and the completion of those contracts.

Business Combinations, Investments and Variable Interest Entities

Business Combinations

The accounting for business combinations requires management to make judgments and estimates related to the fair value of assets acquired, including the identification and valuation of intangible assets, as well as liabilities and contingencies assumed. Such judgments and estimates directly impact the amount of goodwill recognized in connection with an acquisition. Estimating the fair value of acquired assets and assumed liabilities, including intangibles, requires judgments about expected future cash flows, weighted-average cost of capital, discount rates and expected long-term growth rates.

Investments

Investments in entities and corporate joint ventures where we have a non-controlling ownership interest but over which we have the ability to exercise significant influence, are accounted for under the equity method of accounting. We recognize our proportionate share of the entities' net income or loss and do not consolidate the entities' assets and liabilities.

Equity investments in entities over which we do not have the ability to exercise significant influence and whose securities do not have a readily determinable fair value are carried at cost or cost net of other-than-temporary impairments.

Variable Interest Entities

We occasionally form joint ventures and/or enter into arrangements with special purpose limited liability companies for the purpose of bidding and executing on specific projects. We analyze each such arrangement to determine whether it represents a VIE. If the arrangement is determined to be a VIE, we assess whether we are the primary beneficiary of the VIE and are consequently required to consolidate the VIE.

Divestitures

From time-to-time, we may dispose (or management may commit to plans to dispose) of strategic or non-strategic components of the business. Divestitures representing a strategic shift that has (or will have) a major effect in operations and financial results are classified as discontinued operations, whereas non-strategic divestitures remain in continuing operations.

Restructuring Expenses

Restructuring expenses are incurred in connection with programs aimed at reducing our costs. Restructuring costs may include one-time termination of benefits, costs to terminate contracts and other permanent exit costs to consolidate or close facilities directly related to the restructuring program.

One-time involuntary termination benefits are recognized as a liability at estimated fair value when the plan of termination has been communicated to employees and certain other criteria are met. Ongoing termination benefit arrangements are recognized as a liability at estimated fair value when it is probable that amounts will be paid and such amounts are reasonably estimable. Costs associated with exit or disposal activities, including the related one-time and ongoing involuntary termination benefits, are included as "Acquisition, integration and restructuring costs" on the consolidated statements of income.

Revenue Recognition

Our revenues from contracts with customers are from offerings including digital modernization, cyber operations, mission software systems, integrated systems and mission operations, primarily with the U.S. government and its agencies. We also serve various state and local governments, foreign governments and commercial customers.

We perform under various types of contracts, which include firm-fixed-price ("FFP"), time-and-materials ("T&M"), fixed-price-level-of-effort ("FP-LOE"), cost-plus-fixed-fee ("CPFF"), cost-plus-award-fee, cost-plus-incentive-fee and fixed-price-incentive-fee ("FP-IF") contracts.

To determine the proper revenue recognition, we first evaluate whether we have a duly approved and enforceable contract with a customer, in which the rights of the parties and payment terms are identified, and collectability is probable. We also evaluate whether two or more contracts should be combined and accounted for as a single contract, including the task orders issued under an indefinite delivery/indefinite quantity ("IDIQ") award. In addition, we assess contract modifications to determine whether changes to existing contracts should be accounted for as part of the original contract or as a separate contract. Contract modifications generally relate to changes in contract specifications and requirements and do not add distinct services, and therefore are accounted for as part of the original contract. If contract modifications add distinct goods or services and increase the contract value by an amount that reflects the standalone selling price, those modifications are accounted for as separate contracts.

Most of our contracts are comprised of multiple promises including the design and build of software-based systems, integration of hardware and software solutions, running and maintaining of IT infrastructure and procurement services. In all cases, we assess if the multiple promises should be accounted for as separate performance obligations or combined into a single performance obligation. We generally separate multiple promises in a contract as separate performance obligations if those promises are distinct, both individually and in the context of the contract. If multiple promises in a contract are highly interrelated or require significant integration or customization within a group, they are combined and accounted for as a single performance obligation.

Our contracts with the U.S. government often contain options to renew existing contracts for an additional period of time (generally a year at a time) under the same terms and conditions as the original contract, and generally do not provide the customer any material rights under the contract. We account for renewal options as separate contracts when they include distinct goods or services at standalone selling prices.

Contracts with the U.S. government are subject to the Federal Acquisition Regulation ("FAR") and priced on estimated or actual costs of providing the goods or services. The FAR provides guidance on types of costs that are allowable in establishing prices for goods and services provided to the U.S. government and its agencies. Each contract is competitively priced and bid separately. Pricing for non-U.S. government agencies and commercial customers is based on specific negotiations with each customer. In circumstances where the standalone selling price is not directly observable, we estimate the standalone selling price using the expected cost-plus margin approach. Any taxes collected or imposed when determining the transaction price are excluded.

Certain cost-plus and fixed-price contracts contain award fees, incentive fees or other provisions that may either increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. We estimate variable consideration at the most probable amount that we expect to be entitled to, based on the assessment of the contractual variable fee criteria, complexity of work and related risks, extent of customer discretion, amount of variable consideration received historically and the potential of significant reversal of revenue.

We allocate the transaction price of a contract to its performance obligations in the proportion of its respective standalone selling prices. The standalone selling price of the performance obligations is generally based on an expected cost-plus margin approach, in accordance with the FAR. For certain product sales, prices from other standalone sales are used. Substantially all of our contracts do not contain a significant financing component, which would require an adjustment to the transaction price of the contract.

We recognize revenue on our service-based contracts primarily over time as there is continuous transfer of control to the customer over the duration of the contract as the promised services are performed. For U.S. government contracts, continuous transfer of control to the customer is evidenced by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay for costs incurred plus a reasonable profit and take control of any work-in-process. Similarly, for non-U.S. government contracts, the customer typically controls the work-in-process as evidenced by rights to payment for work performed to date plus a reasonable profit to deliver products or services for which we do not have an alternate use. Anticipated losses on service-based contracts are recognized when incurred (generally on a straight-line basis) over the contract term. In certain product sales, where the products have an alternate use, revenue is recognized at a point in time when the customer takes control of the asset usually denoted by possession, transfer of legal title and acceptance by the customer.

On FFP contracts requiring system integration and cost-plus contracts with variable consideration, revenue is recognized over time generally using a method that measures the extent of progress towards completion of a performance obligation, principally using a cost-input method (referred to as the cost-to-cost method). Under the cost-to-cost method, revenue is recognized based on the proportion of total costs incurred to estimated total costs-at-completion ("EAC"). A performance obligation's EAC includes all direct costs such as materials, labor, subcontract costs, overhead and a ratable portion of general and administrative costs. In addition, an EAC of a performance obligation includes future losses estimated to be incurred on onerous contracts, as and when known. On certain other contracts, principally T&M, FP-LOE and CPFF, revenue is generally recognized using the right-to-invoice practical expedient as we are contractually able to invoice the customer based on the control transferred to the customer. Additionally, on maintenance (generally FFP) performance obligations, revenue is recognized over time using a straight-line method as the control of the services is provided to the customer evenly over the period of performance.

For certain performance obligations where we are not primarily responsible for fulfilling the promise to provide the goods or service to the customer, do not have inventory risk and do not have discretion in establishing the price for the goods or service, we recognize revenue on a net basis.

Contract Costs

Contract costs generally include direct costs such as labor, materials, subcontract costs and indirect costs identifiable with or allocable to a specific contract. Costs are expensed as incurred unless they qualify for deferral and capitalization. Contract costs incurred for U.S. government contracts, including indirect costs, are subject to audit and adjustment by the Defense Contract Audit Agency ("DCAA") (see "Note 21—Commitments and Contingencies").

Pre-contract Costs

Costs incurred on projects as pre-contract costs are deferred as assets when we have been requested by the customer to begin work under a new arrangement prior to contract execution and it is probable that we will recover the costs through the issuance of a contract. Pre-contract costs are amortized over the contract period of performance or a specified period of performance.

Transition Costs

Under certain service contracts, costs are incurred, usually at the beginning of the contract performance, to transition the services, employees and equipment to or from the customer, a prior contract or prior contractor. These costs are generally capitalized as deferred assets and amortized on a straight-line basis over the anticipated term of the contract or a specified period of performance, including unexercised option periods that are reasonably certain of being exercised.

Project Assets

Purchases of project assets are capitalized for specific contracts where we maintain ownership of the asset over the life of the contract and the benefit is received over a period of time. Project assets include enterprise software licenses, dedicated hardware, maintenance agreements and significant material purchases and other costs incurred on contracts. Project assets are amortized from the balance sheet using the straight-line method over the estimated useful life of the asset or over the expected term of the period of performance, whichever is shorter.

Changes in Estimates on Contracts

Changes in estimates related to contracts accounted for using the cost-to-cost method of accounting are recognized in the period in which such changes are made for the inception-to-date effect of the changes, with the exception of contracts acquired through a business combination, where the adjustment is made for the period commencing from the date of acquisition.

Changes in estimates on contracts for the periods presented were as follows:


	Year Ended
	December 30, 2022		December 31, 2021		January 1, 2021
	(in millions, except for per share amounts)
Favorable impact	$	146	$	149	$	137
Unfavorable impact	(113)		(102)		(61)
Net favorable impact to income before income taxes	$	33	$	47	$	76

Impact on diluted EPS attributable to Leidos common stockholders	$	0.17	$	0.25	$	0.39

The impact on diluted earnings per share ("EPS") attributable to Leidos common stockholders is calculated using our statutory tax rate.

Revenue Recognized from Prior Obligations

During fiscal 2022, 2021 and 2020, revenue recognized from performance obligations satisfied in previous periods was $9 million, $26 million and $40 million, respectively. The changes primarily relate to revisions of variable consideration, including award and incentive fees, and revisions to estimates at completion resulting from changes in contract scope, mitigation of contract risks or due to true-ups of contract estimates at the end of contract performance.

Selling, General and Administrative Expenses

We classify indirect costs incurred within or allocated to our U.S. government customers as overhead (included in "Cost of revenues") or general and administrative expenses in the same manner as such costs are defined in our disclosure statements under U.S. government Cost Accounting Standards.

Selling, general and administrative expenses include general and administrative, bid and proposal, company-funded research and development expenses, and legal fees and settlements.

We conduct research and development activities under customer-funded contracts and with company-funded research and development funds. Company-funded research and development expense was $116 million, $109 million and $73 million for fiscal 2022, 2021 and 2020, respectively. Expenses for research and development activities performed under customer contracts are charged directly to cost of revenues for those contracts.

Income Taxes

We account for income taxes under the asset and liability method in accordance with the accounting standard for income taxes. The asset and liability method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities. Under this method, changes in tax rates and laws are recognized in income in the period such changes are enacted.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent results of operations. If we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount or would no longer be able to realize our deferred income tax assets in the future as currently recorded, we would make an adjustment to the valuation allowance which would decrease or increase the provision for income taxes.

The provision for federal, state, foreign and local income taxes is calculated on income before income taxes based on current tax law and includes the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provision differs from the amounts currently payable because certain items of income and expense are recognized in different reporting periods for financial reporting purposes than for income tax purposes.

We record liabilities for uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. We recognize interest and penalties related to uncertain tax positions in our income tax expense.

Cash and Cash Equivalents

Our cash equivalents are primarily comprised of investments in several large institutional money market accounts, with original maturity of three months or less. Outstanding payments are included within "Cash and cash equivalents" and "Accounts payable and accrued liabilities" correspondingly on the consolidated balance sheets. At December 30, 2022, and December 31, 2021, $158 million and $138 million, respectively, of outstanding payments were included within "Cash and cash equivalents."

Restricted Cash

We have restricted cash balances, primarily representing advances from customers that are restricted as to use for certain expenditures related to that customer's contract. Restricted cash balances are included as "Other current assets" on the consolidated balance sheets. Our restricted cash balances were $167 million and $148 million at December 30, 2022, and December 31, 2021, respectively.

Receivables

Receivables include amounts billed and currently due from customers, amounts billable where the right to consideration is unconditional and amounts unbilled. Amounts billable and unbilled amounts are recognized at estimated realizable value and consist of costs and fees, substantially all of which are expected to be billed and collected generally within one year. Unbilled amounts also include rate variances that are billable upon negotiation of final indirect rates with the Defense Contract Management Agency.

Cost-reimbursable and T&M contracts are generally billed as costs are incurred. FFP contracts are billed either based on milestones, which are the achievement of specific events as defined in the contract, or based on progress payments, which are interim payments up to a designated amount of costs incurred as work progresses. On certain contracts, the customer withholds a certain percentage of the contract price (retainage). These withheld amounts are included within unbilled receivables and are billed upon contract completion or the occurrence of a specified event, and when negotiation of final indirect rates with the U.S. government is complete. Based on our historical experience, the write-offs of retention balances have not been significant.

When events or conditions indicate that amounts outstanding from customers may become uncollectible, an allowance is estimated and recorded.

Amounts billed and collected on contracts but not yet recorded as revenue because we have not performed our obligation under the arrangement with a customer are deferred and included within "Accounts payable and accrued liabilities" or "Other long-term liabilities" on the consolidated balance sheets.

Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk primarily consist of accounts receivable and derivatives. Since our receivables are primarily with the U.S. government, we do not have exposure to a material credit risk. We manage our credit risk related to derivatives through the use of multiple counterparties with high credit standards.

Inventories

Inventories are valued at the lower of cost or estimated net realizable value. Generally, raw material inventory is valued using the average cost method. Work-in-process inventory may include material costs, labor and allocable overhead costs. The majority of finished goods inventory consists of technology and security products, inspection systems, baggage scanning equipment and small glide munitions. Inventory is evaluated against historical or planned usage to determine appropriate provisions for obsolete inventory.

Goodwill

Goodwill represents the excess of the fair value of consideration transferred, plus the fair value of any non-controlling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill is not amortized, but instead is tested annually for impairment at the reporting unit level and tested more frequently if events or circumstances indicate that the carrying value of the reporting unit may not be recoverable. Our policy is to perform our annual goodwill impairment evaluation as of the first day of the fourth quarter of our fiscal year. During both fiscal 2022 and 2021, we had seven reporting units for the purpose of testing goodwill for impairment.

Goodwill is evaluated for impairment either under a qualitative assessment option or a quantitative approach, which depends on the facts and circumstances of a reporting unit, consideration of the excess of a reporting unit's fair value over its carrying amount in previous assessments and changes in business environment.

When performing a qualitative assessment, we consider factors including, but not limited to, current macroeconomic conditions, industry and market conditions, cost factors, financial performance and other events relevant to the entity or reporting unit under evaluation to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If we determine that it is more likely than not that a reporting unit's fair value is less than its carrying value, a quantitative goodwill impairment test is performed.

When performing a quantitative goodwill impairment test, the reporting unit carrying value is compared to its fair value. Goodwill is deemed impaired if, and the impairment loss is recognized for the amount by which, the reporting unit carrying value exceeds its fair value.

We estimate the fair value of each reporting unit using Level 3 inputs when a quantitative analysis is performed. These analyses rely on significant judgements and assumptions about expected future cash flows, weighted-average cost of capital, discount rates, expected long-term growth rates, operating margins and on the selection of guideline public companies.

Intangible Assets

Acquired intangible assets with finite lives and internally developed software are amortized using the method that best reflects how their economic benefits are utilized or, if a pattern of economic benefits cannot be reliably determined, on a straight-line basis over their estimated useful lives. Program intangible assets are amortized over their respective estimated useful lives in proportion to the pattern of economic benefit based on expected future discounted cash flows. Backlog and trade name intangible assets are amortized on a straight-line basis over their estimated useful lives. Customer relationships and software and technology intangible assets are amortized either on a straight-line basis over their estimated useful lives or over their respective estimated useful lives in proportion to the pattern of economic benefit based on expected future discounted cash flows, as deemed appropriate.

Intangible assets with finite lives are amortized over the following periods:


						Estimated useful lives (in years)
Backlog						1
Customer relationships						8-10
Programs						4-13
Software and technology						3-15
Trade names						3

Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

Intangible assets with indefinite lives are not amortized but are assessed for impairment at the beginning of the fourth quarter and whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

Property, Plant and Equipment

Purchases of property, plant and equipment, including purchases of software and software licenses, as well as costs associated with major renewals and improvements are capitalized. Maintenance, repairs and minor renewals and improvements are expensed as incurred.

Construction in Progress ("CIP") is used to accumulate all costs for projects that are not yet complete. CIP balances are transferred to the appropriate asset account when the asset is capitalized and ready for its intended use.

When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts and any resulting gain or loss is recognized. Depreciation is recognized using the methods and estimated useful lives as follows:

Depreciation method

Estimated useful lives (in years)

Computers and other equipment

Straight-line or declining-balance

2-15

Buildings

Straight-line

Not to exceed 40

Building improvements and leasehold improvements

Straight-line

Shorter of useful life of asset or remaining lease term

Vehicles and transportation equipment

Straight-line

2-15

Office furniture and fixtures

Straight-line or declining-balance

6-9

We evaluate our long-lived assets for potential impairment whenever there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable and the carrying value of the asset exceeds its estimated fair value.

Leases

Lessee

We have facilities and equipment lease arrangements. An arrangement is determined to be a lease at inception if it conveys the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Right-of-use ("ROU") assets represent the right to use an underlying asset over the lease term and lease liabilities represent the obligation to make lease payments arising from the lease.

ROU assets and lease liabilities are recorded on the consolidated balance sheet at lease commencement date based on the present value of the future minimum lease payments over the lease term. We generally do not know the discount rate implicit in our leases; therefore, the discount rate used is our incremental borrowing rate which is determined based on the rate of interest that we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. An ROU asset is initially measured by the present value of the remaining lease payments, plus initial direct costs and prepaid lease payments, less any lease incentives received before commencement. The remaining lease cost is allocated over the remaining lease term on a straight-line basis unless another systematic or rational basis is more representative of the pattern in which the underlying asset is expected to be used.

Certain facility leases contain options to renew or extend the terms of the lease which are included in the determination of the ROU assets and lease liabilities when it is reasonably certain that we will exercise the option. Leases may also include variable lease payments such as an escalation clause based on consumer price index rates, maintenance costs and utilities. Variable lease payments that depend on an index or a rate are included in the determination of ROU assets and lease liabilities using the index or rate at the lease commencement date, whereas variable lease payments that do not depend on an index or rate are recorded as lease expense in the period incurred. At December 30, 2022, certain of the Company's equipment leases include residual value guarantees.

We use the practical expedient to not separate non-lease components from lease components and instead account for both components as a single lease. The practical expedient is applied to all material classes of leased assets except for aircraft, for which we account for the lease component and non-lease component separately.

The related lease payments on short-term facilities and equipment leases are recognized as expense on a straight-line basis over the lease term.

ROU assets are evaluated for impairment in a manner consistent with the treatment of other long-lived assets. ROU assets are assessed for potential impairment whenever there is evidence that events or changes in circumstances indicate that the carrying value of the asset may not be recoverable and the carrying amount of the asset exceeds its estimated fair value. This includes an establishment of a plan of abandonment, which occurs when we have committed to a plan to abandon the lease before the end of its previously estimated useful life and there is no expectation that we will re-enter or re-purpose the space.

Lessor

We are a lessor on certain equipment sales-type and operating lease arrangements with our customers. To be considered lease revenue, the contract must contain a specified asset, we must not have a substantive substitution right, the customer must have the right to direct the use of the specified asset during the period of use and the customer must have the right to obtain substantially all of the economic benefit of the specified asset.

Certain arrangements may contain variable payments that depend on an index or rate and are measured using the index or rate on the commencement date. Variable payments that are not included in the net investments are recorded as revenue as incurred. Arrangements may also contain options to renew or extend the performance period. Option periods are included in the lease term if we determine that it is reasonably certain the customer will exercise an option.

We have arrangements that contain both lease and non-lease components. We account for them as one unit of account if the timing and pattern of transfer is identical for both the lease and the non-lease components and the lease component would be classified as an operating lease if accounted for separately. If both criteria are met and the predominant component is a lease, then the entire arrangement will be accounted for in accordance with ASC 842. If we account for an arrangement both as a lease and non-lease component, then the allocation of consideration for each component will be based on the relative standalone sales price.

Fair Value Measurements

The accounting standard for fair value measurements establishes a three-level fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets for identical assets or liabilities that are observable either directly or indirectly or quoted prices that are not active (Level 2); and unobservable inputs in which there is little or no market data (e.g., discounted cash flow and other similar pricing models), which requires us to develop our own assumptions about the assumptions that market participants would use in pricing the asset or liability (Level 3).

The accounting guidance for fair value measurements requires that we maximize the use of observable inputs and minimize the use of unobservable inputs in determining fair value. The accounting guidance provides for the irrevocable option to elect, on a contract-by-contract basis, to measure certain financial assets and liabilities at fair value at inception of the contract and record any subsequent changes in fair value in earnings. We have not made fair value option elections on any of our financial assets and liabilities.

The fair value of financial instruments is determined based on quoted market prices, if available, or management's best estimate (see "Financial Instruments" below).

Our non-financial instruments measured at fair value on a non-recurring basis include goodwill, indefinite-lived intangible assets and long-lived tangible assets. The valuation methods used to determine fair value require a significant degree of management judgment to determine the key assumptions. As such, we generally classify non-financial instruments as either Level 2 or Level 3 fair value measurements.

Financial Instruments

We are exposed to certain market risks which are inherent in certain transactions entered into during the normal course of business. These transactions include sales or purchase contracts denominated in foreign currencies and exposure to changing interest rates. We manage our risk to changes in interest rates and foreign currency exchange rates through the use of derivative instruments.

For fixed rate borrowings, we use variable interest rate swaps, effectively converting fixed rate borrowings to variable rate borrowings. These swaps are designated as fair value hedges. The fair value of these interest rate swaps is determined based on observed values for underlying interest rates on the LIBOR yield curve (Level 2).

For variable rate borrowings, we use fixed interest rate swaps, effectively converting a portion of the variable interest rate payments to fixed interest rate payments. These swaps are designated as cash flow hedges. The fair value of these interest rate swaps is determined based on observed values for the underlying interest rates (Level 2).

We enter into foreign currency forward contracts in order to mitigate fluctuations in our earnings and cash flows due to changes in foreign currency exchange rates. The foreign currency forward contracts are not designated as hedges and hedge accounting does not apply. We do not hold derivative instruments for trading or speculative purposes.

Our defined benefit plan assets consist of investments in pooled funds that contain investments with values based on quoted market prices, but for which the pools are not valued on a daily quoted market basis (Level 2).

Stock-Based Compensation

We account for stock-based compensation at the grant date based on the fair value of the award and recognize expense over the requisite service period, which is generally the vesting period, net of an estimated forfeiture rate.

The fair value of restricted stock awards and performance-based stock awards is based on the closing price of Leidos common stock on the date of grant. The fair value of performance-based stock awards with market conditions is based on using a Monte Carlo simulation.

The fair value of stock option awards granted is based on using the Black-Scholes-Merton option pricing model. The estimation of stock option fair value requires management to make estimates and judgments about, among other things, employee exercise behavior, forfeiture rates and the expected volatility of Leidos common stock over the expected option term. These judgments directly affect the amount of compensation expense that will ultimately be recognized.

Foreign Currency

The financial statements of consolidated international subsidiaries, for which the functional currency is not the U.S. dollar, are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and a weighted average exchange rate over the reporting period for revenues, expenses, gains and losses. Translation adjustments are recorded as accumulated other comprehensive loss in stockholders' equity. Gains and losses due to movements in foreign currency exchange rates are recognized as "Other expense, net" on the consolidated statements of income.

Revenues

Note 4—Revenues

Remaining Performance Obligations

Remaining performance obligations ("RPO") represent the expected value of exercised contracts, both funded and unfunded, less revenue recognized to date. RPO does not include unexercised option periods and future potential task orders expected to be awarded under IDIQ contracts, General Services Administration Schedule or other master agreement contract vehicles, with the exception of certain IDIQ contracts where task orders are not competitively awarded and separately priced but instead are used as a funding mechanism, and where there is a basis for estimating future revenues and funding on future anticipated task orders.

As of December 30, 2022, we had $15.4 billion of RPO and expect to recognize approximately 57% and 74% over the next 12 months and 24 months, respectively, with the remaining to be recognized thereafter.

Disaggregation of Revenues

We disaggregate revenues by customer-type, contract-type and geographic location for each of our reportable segments. These categories represent how the nature, timing and uncertainty of revenues and cash flows are affected.

Disaggregated revenues by customer-type were as follows:

The majority of our revenues are generated from U.S. government contracts, either as a prime contractor or as a subcontractor to other contractors. Revenues from the U.S. government can be adversely impacted by spending caps or changes in budgetary priorities of the U.S. government, as well as delays in program start dates or the award of a contract.

Cost-reimbursement and FP-IF contracts are generally lower risk and have lower profits. T&M and FP-LOE contracts are also lower risk, but profits may vary depending on actual labor costs compared to negotiated contract billing rates. FFP contracts offer the potential for higher profits while increasing the exposure to risk of cost overruns.

Disaggregated revenues by geographic location were as follows:

Total	$	7,339	$	2,903	$	1,955	$	12,197

Our international business operations, primarily located in Australia and the U.K., are subject to additional and different risks than our U.S. business. Failure to comply with U.S. government laws and regulations applicable to international business, such as the Foreign Corrupt Practices Act or U.S. export control regulations, could have an adverse impact on our business with the U.S. government.

In some countries, there is an increased chance for economic, legal or political changes that may adversely affect the performance of our services, sales of products or repatriation of profits. International transactions can also involve increased financial and legal risks arising from foreign exchange variability, imposition of tariffs or additional taxes and restrictive trade policies and delays or failure to collect amounts due to differing legal systems.

Revenues by contract-type, customer-type and geographic location exclude lease income of $109 million, $120 million and $100 million for fiscal 2022, 2021 and 2020, respectively (see "Note 10—Leases").

Contract Assets and Liabilities

Performance obligations are satisfied either over time as work progresses or at a point in time. Firm-fixed-price contracts are typically billed to the customer using milestone payments while cost-reimbursable and time and materials contracts are typically billed to the customer on a monthly or bi-weekly basis as indicated by the negotiated billing terms and conditions of the contract. As a result, the timing of revenue recognition, customer billings and cash collections for each contract results in a net contract asset or liability at the end of each reporting period.

Contract assets consist of unbilled receivables, which is the amount of revenue recognized that exceeds the amount billed to the customer, where right to payment is not solely subject to the passage of time. Unbilled receivables exclude amounts billable where the right to consideration is unconditional. Contract liabilities consist of deferred revenue, which represents cash advances received prior to performance for programs and billings in excess of revenue recognized.

The components of contract assets and contract liabilities consisted of the following:


	Balance sheet line item	December 30, 2022		December 31, 2021
		(in millions)
Contract assets - current:
Unbilled receivables	Receivables, net	$	1,010	$	1,022

Contract liabilities - current:
Deferred revenue(1)	Accounts payable and accrued liabilities	$	380	$	364

Contract liabilities - non-current:
Deferred revenue(1)	Other long-term liabilities	$	29	$	24

(1) Certain contracts record revenue on a net contract basis, and therefore, the respective deferred revenue balance will not fully convert to revenue.

Revenue recognized during fiscal 2022 and 2021 of $270 million and $340 million, respectively, was included as a contract liability at December 31, 2021, and January 1, 2021, respectively.

There were no impairment losses recognized on contract assets during fiscal 2022, 2021 and 2020.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Business Combination and Asset Acquisition [Abstract]

Acquisitions and Divestitures

Note 5—Acquisitions and Divestitures

Acquisitions

We may acquire businesses as part of our growth strategy to provide new or enhance existing capabilities and offerings to customers. During fiscal 2022, we completed the acquisition of Cobham Aviation Services Australia’s Special Mission business ("Cobham Special Mission"). During fiscal 2021, we completed the acquisitions of Gibbs & Cox, 1901 Group, LLC ("1901 Group"), and an immaterial strategic acquisition. During fiscal 2020, we completed the acquisitions of L3Harris Technologies' security detection and automation businesses (the "SD&A Businesses") and Dynetics, Inc. ("Dynetics").

Cobham Special Mission Acquisition

On October 30, 2022 (the "Agreement Date"), we completed the acquisition of Cobham Special Mission for a preliminary purchase consideration of $295 million Australian dollars, net of $10 million of Australian dollars acquired, approximately $190 million United States dollars, net of $6 million of cash acquired, which is subject to working capital adjustments. Cobham Special Mission provides airborne border surveillance and search and rescue services to the Australian Federal Government.

The preliminary goodwill recognized of $26 million represents intellectual capital and the acquired assembled workforce, neither of which qualify for recognition as a separate intangible asset. None of the goodwill recognized is tax deductible.

In connection with this acquisition, we acquired preliminary fair value of property, plant and equipment of $147 million at the Agreement Date. The following table summarizes the preliminary fair value of intangible assets acquired at the Agreement Date and the related weighted average amortization period:


	Weighted average amortization period	Fair value
	(in years)	(in millions)
Programs	7	$	21
Technology	9	4
Total	7	$	25

As of December 30, 2022, we had not finalized the determination of fair values allocated to assets and liabilities, including, but not limited to, property, plant and equipment, intangible assets, accounts receivables, accounts payable and accrued liabilities and other long-term liabilities.

For fiscal 2022, $21 million of revenues related to the Cobham Special Mission acquisition were recognized within the Defense Solutions reportable segment.

Gibbs & Cox Acquisition

On May 7, 2021 (the "Purchase Date"), we completed the acquisition of Gibbs & Cox for purchase consideration of approximately $375 million, net of $1 million of cash acquired. Gibbs & Cox is an independent engineering and design firm specializing in naval architecture, marine engineering, management support and engineering consulting.

The final goodwill recognized of $276 million represents intellectual capital and the acquired assembled workforce, neither of which qualify for recognition as a separate intangible asset. All of the goodwill recognized is tax deductible.

The following table summarizes the fair value of intangible assets acquired at the Purchase Date and the related weighted average amortization period:

For fiscal 2022 and fiscal 2021, $114 million and $98 million, respectively, of revenues related to the Gibbs & Cox acquisition were recognized within the Defense Solutions reportable segment.

1901 Group Acquisition

On January 14, 2021 (the "Closing Date"), we completed the acquisition of 1901 Group for purchase consideration of $212 million, net of $2 million of cash acquired.

As of December 31, 2021, we had completed the determination of fair values of the acquired assets and liabilities assumed. The final goodwill recognized of $123 million represents intellectual capital and the acquired assembled workforce, none of which qualify for recognition as separate intangible assets. Of the goodwill recognized, $118 million is tax deductible.

The following table summarizes the fair value of intangible assets acquired at the Closing Date and the related weighted average amortization period:


	Weighted average amortization period	Fair value

SD&A Businesses Acquisition

On May 4, 2020 (the "Transaction Date"), we completed the acquisition of the SD&A Businesses. The SD&A Businesses were acquired for cash consideration of $1,019 million, net of $27 million of cash acquired. The purchase consideration includes the initial cash payment of $1,015 million plus a $31 million payment for contractual net working capital acquired. The SD&A Businesses provide airport and critical infrastructure screening products, automated tray return systems and other industrial automation products. The addition of the SD&A Businesses will expand the scope and scale of our global security detection and automation offerings.

The final fair values of the assets acquired and liabilities assumed at the Transaction Date were as follows (in millions):


Current assets	$	287
Intangible assets	355
Other assets	67
Current liabilities	(140)
Long-term liabilities	(97)
Total identifiable net assets acquired	472

For fiscal 2022, fiscal 2021 and fiscal 2020, $330 million, $291 million and $243 million, respectively, of revenues related to the SD&A Businesses were recognized within the Civil reportable segment.

Dynetics Acquisition

On January 31, 2020 (the "Acquisition Date"), we completed our acquisition of Dynetics, an industry-leading applied research and national security solutions company. The addition of Dynetics will accelerate opportunities within our innovation engine that researches and develops new technologies and solutions to address the most challenging needs of our customers. All of the issued and outstanding shares of common stock of Dynetics were purchased for $1.64 billion, net of cash acquired.

The final fair values of the assets acquired and liabilities assumed at the Acquisition Date were as follows (in millions):

Total acquisition and integration costs	$	16	$	24	$	35

These acquisition and integration costs have been primarily recorded within Corporate and presented in "Acquisition, integration and restructuring costs" on the consolidated statement of income.

Divestitures

Aviation & Missile Solutions LLC ("AMS")

On November 22, 2021, our Defense Solutions reportable segment signed a definitive agreement to dispose of its AMS business in order to focus on leading-edge and technologically advanced services, solutions and products. The divestiture was completed on April 29, 2022. The net sales price was $15 million and net assets of $19 million were divested. The loss was recorded in "Other expense, net" on the consolidated statements of income. This disposition did not meet the criteria to be classified as a discontinued operation in the financial statements.

Sale of Accounts Receivable

We have entered into purchase agreements with a financial institution which provide us the election to sell accounts receivable at a discount. The receivables sold are typically collectable from our customers within 30 days of the sale date. During fiscal 2022, 2021 and 2020, we sold $209 million, $693 million and $1,866 million, respectively, of accounts receivable under the agreements and received proceeds of $209 million, $693 million and $1,864 million, respectively. These activities are classified as operating activities in the consolidated statements of cash flows.

These transfers have been recognized as a sale, as the receivables had been legally isolated from Leidos, the financial institution had the right to pledge or exchange the assets received and we did not maintain effective control over the transferred accounts receivable. As of December 30, 2022, and December 31, 2021, all sold receivables had been remitted to the financial institution.

The following table presents changes in the carrying amount of goodwill by reportable segment:


	Defense Solutions		Civil		Health		Total

(1) Carrying amount includes accumulated impairment losses of $369 million and $117 million within the Health and Civil segments, respectively.

In the fourth quarter of fiscal 2022, we performed a qualitative analysis for certain reporting units which determined that it was more likely than not that the fair values of these reporting units were in excess of the individual reporting units' carrying values. We performed a quantitative analysis for certain reporting units and concluded that these reporting units were not impaired as their fair values exceeded their carrying values. The quantitative analysis for the Security Enterprise Solutions reporting unit, which holds goodwill of $899 million as of December 30, 2022, showed that fair value exceeded carrying value by 13%. Operations of the reporting unit rely heavily on the sales and servicing of security and detection products, which have been negatively impacted by COVID-19. The forecasts utilized to estimate the fair value of the Security Enterprise Solutions reporting unit assume continued global operations in all of our existing markets and a gradual improvement in the global aviation security product and related service sales, reaching pre-COVID-19 levels by fiscal 2025. In the event that there are significant unfavorable changes to the forecasted cash flows of the reporting unit (including if the impact of COVID-19 on passenger travel levels is more prolonged or severe than what is incorporated into our forecast), terminal growth rates or the cost of capital used in the fair value estimates, we may be required to record a material impairment of goodwill or intangible assets at a future date.

In the fourth quarter of fiscal 2021, we performed a qualitative analysis for certain reporting units which determined that it was more likely than not that the fair values of these reporting units were in excess of the individual reporting units' carrying values. For reporting units whose composition was affected by a reorganization, or those for which an indication of impairment exists, a quantitative assessment was performed. The quantitative analysis for the Security Enterprise Solutions reporting unit within the Civil reportable segment, which holds goodwill in the amount of $926 million as of December 31, 2021, showed that the fair value of the reporting unit exceeded the carrying value.

In the fourth quarter of fiscal 2020, we performed a qualitative analysis for all reporting units and determined that it was more likely than not that the fair values of the reporting units were in excess of the individual reporting units carrying values, and as a result, a quantitative step one analysis was not necessary.

As a result, no goodwill impairments were identified as part of the annual goodwill impairment evaluation for the periods mentioned above.

Intangible Assets

Intangible assets, net consisted of the following:

Total intangible assets	$	2,130	$	(1,178)	$	952	$	2,184	$	(1,007)	$	1,177

(1) IPR&D assets are indefinite-lived at the acquisition date until placed into service, at which time such assets will be reclassified to a finite-lived amortizable intangible asset.

Amortization expense related to intangible assets was $230 million, $228 million and $198 million for fiscal 2022, 2021 and 2020, respectively.

The estimated annual amortization expense related to finite-lived intangible assets as of December 30, 2022, is as follows:


Fiscal Year Ending
	(in millions)
2023	$	208
2024	153
2025	124
2026	99
2027	71
2028 and thereafter	201
	$	856

Actual amortization expense in future periods could differ from these estimates as a result of future acquisitions, divestitures, impairments, the outcome and timing of completion of in-process research and development projects and other factors.

In the fourth quarter of fiscal 2022, we evaluated indefinite-lived intangibles for impairment and concluded that no impairment was necessary.

During fiscal 2022, we reduced our leased space by exiting and consolidating underutilized buildings as part of an ongoing facility rationalization effort. We used discounted cash flow models to estimate the fair values of the affected assets and as a result, we recorded impairments of ROU and other assets in the amount of $37 million. The impairment charges were allocated across our reportable segments and to Corporate.

During fiscal 2020, we made a decision to vacate one of our facilities. The carrying amount was determined to be less than the expected recovery from sublease income and as a result, we recorded an impairment charge of $11 million, which was recorded within our Health reportable segment.

Total lease cost for the periods presented consisted of the following:

Financial liabilities:
Derivatives	$	—	$	—	$	53	$	53

As of December 30, 2022, our derivatives primarily consisted of the cash flow interest rate swaps on $1.0 billion of the variable rate senior unsecured term loan (see "Note 12—Derivative Instruments"). The fair value of the cash flow interest rate swaps is determined based on observed values for underlying interest rates on the LIBOR yield curve (Level 2 inputs).

Financial instruments measured on a recurring basis at fair value also include our defined benefit plan assets (Level 2 inputs). See "Note 19—Retirement Plans" for further details on these investments.

The carrying amounts of our financial instruments, other than derivatives, which include cash equivalents, accounts receivable, accounts payable and accrued expenses, are reasonable estimates of their related fair values. The carrying value of our notes receivable of $12 million and $15 million as of December 30, 2022 and December 31, 2021, respectively, approximates fair value as the stated interest rates within the agreements are consistent with the current market rates used in notes with similar terms in the market (Level 2 inputs).

As of December 30, 2022 and December 31, 2021, the fair value of debt was $4.6 billion and $5.4 billion, respectively, and the carrying amount was $4.9 billion and $5.1 billion, respectively (see "Note 13—Debt"). The fair value of debt is determined based on current interest rates available for debt with terms and maturities similar to our existing debt arrangements (Level 2 inputs).

On October 30, 2022, May 7, 2021, and January 14, 2021, non-financial instruments measured at fair value on a non-recurring basis were recorded in connection with the acquisitions of Cobham Special Mission, Gibbs & Cox and 1901 Group, respectively. The fair values of the assets acquired and liabilities assumed were determined using Level 3 inputs. See "Note 5—Acquisitions and Divestitures" for further details on these acquisitions. As of December 30, 2022 and December 31, 2021, we did not have any assets or liabilities measured at fair value on a non-recurring basis.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Derivative Instruments

Note 12—Derivative Instruments

The fair value of the interest rate swaps was as follows:



	Balance sheet line item	December 30, 2022		December 31, 2021
		(in millions)
Asset derivatives:
Cash flow interest rate swaps	Other long-term assets	$	20	$	—
Liability derivatives:
Cash flow interest rate swaps	Other long-term liabilities	$	—	$	53

The cash flows associated with the interest rate swaps are classified as operating activities in the consolidated statements of cash flows.

During fiscal 2022, we entered into a foreign currency forward contract to offset foreign currency fluctuations of the $310 million Australian dollar preliminary purchase price for the Cobham Special Mission acquisition against the U.S. dollar. We realized a loss of $18 million resulting from the settlement of the foreign currency forward contract. The loss was recorded within Corporate and presented in "Other expense, net" on the consolidated statements of income and the settlement associated with the foreign currency forward contract was classified as investing activities in the consolidated statements of cash flows.

Cash Flow Hedges

We have interest rate swap agreements to hedge the cash flows of $1.0 billion of the variable rate senior unsecured term loan (the "Variable Rate Loan"). These interest rate swap agreements have a maturity date of August 2025 and a fixed interest rate of 3.00%. The objective of these instruments is to reduce variability in the forecasted interest payments of the Variable Rate Loan, which are based on the LIBOR rate. Under the terms of the interest rate swap agreements, we receive monthly variable interest payments based on the one-month LIBOR rate and pay interest at a fixed rate.

The interest rate swap transactions were accounted for as cash flow hedges. The gain/loss on the swap is reported as a component of other comprehensive income (loss) and is reclassified into earnings when the interest payments on the underlying hedged items impact earnings. A qualitative assessment of hedge effectiveness is performed on a quarterly basis, unless facts and circumstances indicate the hedge may no longer be highly effective.

The effect of the cash flow hedges on other comprehensive income (loss) and earnings for the periods presented was as follows:


	Year Ended
	December 30, 2022		December 31, 2021		January 1, 2021

Amount reclassified from accumulated other comprehensive income (loss) to interest expense, net	11		19		14

We expect to reclassify net gains of $14 million from accumulated other comprehensive loss into earnings during the next 12 months.

Term Loans and Revolving Credit Facility

On May 6, 2022, we entered into a 364-day term loan credit agreement ("Term Loan Agreement") with certain financial institutions, which provided for a senior unsecured term loan facility in an aggregate principal amount of $380 million. The proceeds of the Term Loan Agreement were used to repay the $380 million senior unsecured term loan entered into on May 7, 2021.

Borrowings under the Term Loan Agreement bear interest at a rate based on the Secured Overnight Financing Rate plus 1.10%, or an alternate base rate at our option.

The financial covenants in the Term Loan Agreement require that we maintain, as of the last day of each fiscal quarter, a ratio of adjusted consolidated total debt to consolidated EBITDA of not more than 3.75 to 1.00, subject to increases to 4.50 to 1.00 following a material acquisition, and a ratio of EBITDA to consolidated interest expense of not less than 3.50 to 1.00.

On May 7, 2021, we entered into a credit agreement with certain financial institutions, which provided for a senior unsecured term loan facility in an aggregate principal amount of $380 million with maturity 364 days after the credit agreement date. The proceeds were used to fund the acquisition of Gibbs & Cox. The term loan was repaid on May 6, 2022.

We have a Credit Agreement (the "Credit Agreement") with certain financial institutions, which provided for a senior unsecured term loan facility in an aggregate principal amount of $1.9 billion (the "Term Loan Facility") and a $750 million senior unsecured revolving facility (the "Revolving Facility" and, together with the Term Loan Facility, the "Credit Facilities"). The Credit Facilities are scheduled to mature in January 2025, with the Revolving Facility subject to two additional one year extensions. As of December 30, 2022, and December 31, 2021, there were no borrowings outstanding under the Revolving Facility.

Borrowings under the Credit Agreement bear interest at a rate determined, at our option, based on either an alternate base rate or a LIBOR rate plus, in each case, an applicable margin that varies depending on our credit rating. The applicable margin range for LIBOR-denominated borrowings is from 1.13% to 1.75%. Based on our current ratings, the applicable margin for LIBOR-denominated borrowings is 1.38%.

The financial covenants in the Credit Agreement require that we maintain, as of the last day of each fiscal quarter, a ratio of adjusted consolidated total debt to consolidated EBITDA of not more than 3.75 to 1.00, subject to two increases to 4.50 to 1.00 following a material acquisition, and a ratio of EBITDA to consolidated interest expense of not less than 3.50 to 1.00.

Commercial Paper

On July 12, 2021, we established a commercial paper program in which the Company may issue short-term unsecured commercial paper notes ("Commercial Paper Notes") not to exceed $750 million. The proceeds will be used for general corporate purposes, including working capital, capital expenditures, acquisitions and share repurchases.

The Commercial Paper Notes will be issued in minimum denominations of $0.25 million and will have maturities of up to 397 days from the date of issuance. The Commercial Paper Notes will bear either a stated or floating interest rate, if interest bearing, or will be sold at a discount from the face amount. As of December 30, 2022, and December 31, 2021, we did not have any Commercial Paper Notes outstanding.

Principal Payments and Debt Issuance Costs

We made principal payments on our debt of $545 million, $106 million and $731 million during fiscal 2022, 2021 and 2020, respectively. This activity included required principal payments on our term loans of $476 million, $96 million and $72 million during fiscal 2022, 2021 and 2020, respectively. During fiscal 2020, we made $4,925 million of principal repayments for outstanding debt and retired the $450 million senior notes.

Principal payments are made quarterly on our Term Loan Facility, with the majority of the principal due at maturity. Interest on the Term Loan Facility is payable on a periodic basis, which must be at least quarterly. Principal on the Term Loan Agreement is due at maturity and interest is paid monthly. Interest on the senior fixed rate unsecured notes is payable on a semi-annual basis with principal payments due at maturity.

Amortization of debt discount and deferred financing costs was $11 million for both fiscal 2022 and 2021, and $16 million for fiscal 2020.

The Credit Facilities, the Term Loan Agreement, Commercial Paper Notes, senior unsecured term loans and notes are fully and unconditionally guaranteed and contain certain customary restrictive covenants, including among other things, restrictions on our ability to create liens and enter into sale and leaseback transactions under certain circumstances. We were in compliance with all covenants as of December 30, 2022.

Earnings Per Share ("EPS")

Earnings Per Share [Abstract]

Earnings Per Share ("EPS")

Note 16—Earnings Per Share ("EPS")

Basic EPS is computed by dividing net income attributable to Leidos common stockholders by the basic weighted average number of shares outstanding. Diluted EPS is calculated to give effect to all potentially dilutive common shares that were outstanding during the reporting period. The dilutive effect of outstanding equity-based compensation awards is reflected in diluted EPS by application of the treasury stock method, only in periods in which such effect would have been dilutive for the period.

We issue unvested stock awards that have forfeitable rights to dividends or dividend equivalents. These stock awards are dilutive common share equivalents subject to the treasury stock method.

The weighted average number of shares used to compute basic and diluted EPS attributable to Leidos stockholders were:


	Year Ended
	December 30, 2022	December 31, 2021	January 1, 2021
	(in millions)
Basic weighted average number of shares outstanding	137	141	142
Dilutive common share equivalents—stock options and other stock awards	1	2	2
Diluted weighted average number of shares outstanding	138	143	144

Anti-dilutive stock-based awards are excluded from the weighted average number of shares outstanding used to compute diluted EPS. The total outstanding stock options and vesting stock awards that were anti-dilutive were 1 million for both fiscal 2022 and 2021. There were no significant anti-diluted equity awards for fiscal 2020.

Share Repurchases

During fiscal 2021 and 2020, we made open market repurchases of our common stock for an aggregate purchase price of $237 million and $67 million, respectively. There were no open market share repurchases in fiscal 2022.

In fiscal 2022, we entered into Accelerated Share Repurchase agreement with a financial institution to repurchase shares of our outstanding common stock. We paid $500 million to the financial institution and received 4.8 million shares.

The repurchases were recorded to "Additional paid-in capital" in the consolidated balance sheets. All shares delivered were immediately retired.

Stock-Based Compensation

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

Note 17—Stock-Based Compensation

Plan Summaries

As of December 30, 2022, we had stock-based compensation awards outstanding under the following plans: the 2017 Omnibus Incentive Plan, the 2006 Equity Incentive Plan, as amended, and the 2006 Employee Stock Purchase Plan, as amended ("ESPP"). We issue new shares upon the vesting of stock units or exercising of stock options under these plans.

The 2017 Omnibus Incentive Plan provides Leidos and its affiliates' employees, directors and consultants the opportunity to receive various types of stock-based compensation awards, such as stock options, restricted stock units and performance-based awards, as well as cash awards. We grant service-based awards that generally vest or become exercisable 25% a year over four years or cliff vest in three years. As of December 30, 2022, 3.5 million shares of Leidos' stock were reserved for future issuance under the 2017 Omnibus Incentive Plan and the 2006 Equity Incentive Plan.

We offer eligible employees the opportunity to defer restricted stock units into an equity-based deferred equity compensation plan, the Key Executive Stock Deferral Plan ("KESDP"). Prior to 2013, we offered an additional opportunity for deferrals into the Management Stock Compensation Plan ("MSCP"). Benefits from these plans are payable in shares of Leidos' stock that are held in a trust for the purpose of funding shares to the plans' participants. Restricted stock units deferred under the KESDP are counted against the total shares available for future issuance under the 2017 Omnibus Incentive Plan. All awards under the MSCP are fully vested and the plan does not provide for a maximum number of shares available for future issuance.

Our ESPP allows eligible employees to purchase shares of Leidos' stock at a discount of up to 15% of the fair market value on the date of purchase. During fiscal 2022, 2021 and 2020, the discount was 10% of the fair market value on the date of purchase. During fiscal 2022, 2021 and 2020, $45 million, $39 million and $32 million, respectively, was received from ESPP plan participants for the issuance of Leidos' stock. A total of 2.9 million shares remain available for future issuance under the ESPP.

Stock-based compensation and related tax benefits recognized under all plans were as follows:

Tax benefits recognized from stock-based compensation	16		17		15

Stock Options

Stock options are granted with exercise prices equal to the fair market value of Leidos' common stock on the date of grant and for terms not greater than ten years. Stock options have a term of seven years and a vesting period of four years, except for stock options granted to our outside directors, which have a vesting period of the earlier of one year from grant date or the next annual meeting of stockholders following grant date.

The fair value of the stock option awards is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The fair value of the stock option awards to employees are expensed on a straight-line basis over the vesting period of four years, except for stock options granted to our outside directors, which is recognized over the vesting period of one year or less.

During fiscal 2022, 2021 and 2020, we used a blended approach to measure expected volatility that is based on our weighted average historical and implied volatilities.

The risk-free rate is derived using the yield curve of a zero-coupon U.S. Treasury bond with a maturity equal to the expected term of the stock option on the grant date. To determine the expected term, we use the midpoint scenario with a one-year grant date filter assumption for outstanding options and we use historical data to estimate forfeitures. The weighted average grant-date fair value and assumptions used to determine fair value of stock options granted for the periods presented were as follows:


	Year Ended
	December 30, 2022			December 31, 2021			January 1, 2021

As of December 30, 2022, there was $6 million of unrecognized compensation cost, net of estimated forfeitures, related to stock options, which is expected to be recognized over a weighted-average period of 2.1 years. Tax benefits from stock options exercised for fiscal 2022, 2021 and 2020 were $9 million, $6 million and $7 million, respectively.

Restricted Stock Units and Awards

Compensation expense is measured at the grant date fair value and generally recognized over the vesting period of either three to four years based upon required service conditions and in some cases revenue or EPS-based performance conditions.

Restricted stock units and awards activity for each of the periods presented was as follows:


	Shares of stock under stock awards	Weighted average grant- date fair value
	(in millions)

Unvested stock awards at December 30, 2022	1.3	$	98.52

As of December 30, 2022, there was $52 million of unrecognized compensation cost, net of estimated forfeitures, related to restricted stock units, which is expected to be recognized over a weighted average period of 2.0 years. The fair value of restricted stock units that vested in fiscal 2022, 2021 and 2020 was $52 million, $48 million and $58 million, respectively. In addition, the fair value of dividend equivalents with respect to restricted stock units that vested in fiscal 2022, 2021 and 2020 was immaterial.

Performance-Based Stock Awards

Performance-based stock awards vest and the stock is issued at the end of a three-year period based upon the achievement of specific performance criteria, with the number of shares ultimately awarded, if any, ranging up to 150% of the specified target awards. If performance is below the threshold level of performance, no shares will be issued.

For awards granted during fiscal 2022, 2021 and 2020, the target number of shares of stock granted under the awards will vest and the stock will be issued at the end of a three-year period based on a three-year cycle performance period and the actual number of shares to be issued will be based upon the achievement of the three-year cycle's performance criteria. Also, during fiscal 2022, 2021 and 2020, we granted performance-based awards with market conditions. These market conditions grants represent the target number of shares and the actual number of shares to be awarded upon vesting may be higher or lower depending upon the achievement of the relevant market conditions. The target number of shares granted under the market conditions grants will vest and the stock will be issued at the end of a three-year period based on the attainment of certain total shareholder return performance measures and the employee's continued service through the vest date.

Performance-based stock award activity for each of the periods presented was as follows:


	Expected number of shares of stock to be issued under performance-based stock awards	Weighted average grant- date fair value

Awards vested	(0.2)	67.79
Unvested at December 30, 2022	0.5	$	106.70

The weighted average grant date fair value for performance-based stock, excluding those with a market condition, during fiscal 2022, 2021 and 2020 was $105.07, $89.26 and $106.80, respectively. The weighted average grant date fair value for performance-based stock with market conditions that were granted during fiscal 2022, 2021 and 2020 was $129.42, $88.21 and $127.92, respectively, and was calculated using the Monte Carlo simulation.

The Monte Carlo simulation assumptions used for the periods presented were as follows:


	Year Ended
	December 30, 2022			December 31, 2021			January 1, 2021

As of December 30, 2022, there was $21 million of unrecognized compensation cost, net of estimated forfeitures, which is expected to be recognized over a weighted average period of 1.7 years. The fair value of performance-based stock awards that vested in fiscal 2022, 2021 and 2020 was $17 million, $19 million, and $25 million, respectively.

At December 30, 2022, we had state net operating losses of $62 million and state tax credits of $2 million. Both will begin to expire in fiscal 2023; however, we expect to utilize $45 million and $2 million of these state net operating losses and state tax credits, respectively. We had foreign tax credits of $18 million that will begin to expire in fiscal 2030. We expect to utilize $7 million of these foreign tax credits. We also had foreign net operating losses of $35 million, which do not expire. We expect to utilize $2 million of these foreign net operating losses.

Our valuation allowance for deferred tax assets was $24 million and $21 million as of December 30, 2022 and December 31, 2021, respectively.

At December 30, 2022, and December 31, 2021, the balance of unrecognized tax benefits included liabilities for uncertain tax positions of $92 million and $2 million, respectively, which were classified as other long-term liabilities on the consolidated balance sheets. At January 1, 2021, the balance of unrecognized tax benefits included liabilities for uncertain tax positions of $6 million, $4 million of which were classified as other long-term liabilities on the consolidated balance sheets.

Beginning in 2022, the Tax Cuts and Jobs Act of 2017 (“TCJA”) eliminated the option to currently deduct certain research and development costs for tax purposes and requires taxpayers to capitalize and amortize research costs over five years. Based upon our interpretation of the law as currently enacted, we recorded the estimated fiscal 2022 impact, resulting in increases of $130 million to both our income taxes payable and net deferred tax assets. Our unrecognized tax benefits also increased by $91 million with a corresponding increase to net deferred tax assets. The actual impact will depend on the amount of research and development costs the Company will incur, whether Congress modifies or repeals this provision and whether new guidance and interpretive rules are issued by the U.S. Treasury, among other factors.

We file income tax returns in the United States and various state and foreign jurisdictions. For the year ended December 30, 2022, we are participating in the Internal Revenue Service (“IRS”) Compliance Assurance Process ("CAP"), a real-time audit of our consolidated federal corporate income tax return. The IRS has examined our consolidated federal income tax returns through the year ended January 3, 2020. For the years ended January 1, 2021 and December 31, 2021, we were selected to participate in the phase of CAP reserved for taxpayers whose risk of noncompliance does not warrant use of IRS resources. We believe that participation in CAP should reduce tax-related uncertainties, if any. Additionally, with a few exceptions, as of December 30, 2022, we are no longer subject to state, local, or foreign examinations by the tax authorities for fiscal years ended on or before December 28, 2018.

During the next 12 months, we expect our balance of unrecognized tax benefits to decrease by $20 million related to capitalized research and development costs. While we believe we have adequate accruals for uncertain tax positions, the tax authorities may determine that we owe taxes in excess of recorded accruals or the recorded accruals may be in excess of the final settlement amounts agreed to by tax authorities.

Retirement Plans	12 Months Ended
Retirement Plans	Dec. 30, 2022
Retirement Benefits [Abstract]
Retirement Plans	Note 19—Retirement Plans Defined Contribution Plans We sponsor various defined contribution plans in which most employees are eligible to participate. These plans allow eligible participants to contribute a portion of their income through payroll deductions and Leidos may also make discretionary contributions. Company contributions were $145 million, $131 million and $120 million for fiscal 2022, 2021 and 2020, respectively. Deferred Compensation Plans We maintain three deferred compensation plans, the Keystaff Deferral Plan ("KDP"), the KESDP and the MSCP (the "Plans"), for the benefit of certain management or highly compensated employees or members of the Board of Directors. The Plans allow eligible participants to elect to defer a portion of their salary, and all or a portion of certain bonuses, including restricted stock unit awards. Directors may also elect to defer their cash compensation in addition to their restricted stock unit awards. Deferred balances in the Plans are paid in lump sum or installments upon retirement, termination or the elected specified date. We do not make any contributions to the KDP but maintain participant accounts for deferred amounts and investments. We maintain a rabbi trust for the purpose of funding benefit payments to the KDP participants. Participants may allocate deferred salary and cash bonus amounts into a variety of designated investment options, with gains and losses based on the elected investment option performance with the participant assuming all risks related to future returns of their contributions. Under the KESDP, eligible participants may elect to defer in share units all or a portion of certain cash bonuses and restricted stock unit awards granted under the previous 2006 Equity Incentive Plan and the current 2017 Omnibus Incentive Plan (see "Note 17—Stock-Based Compensation"). Under the MSCP, restricted stock share units are fully vested and no further deferrals into the plan are made. We do not make any contributions to the accounts of KESDP or MSCP participants. Benefits from the KESDP and MSCP are payable in shares of Leidos common stock held in a rabbi trust for the purpose of funding benefit payments to KESDP and MSCP participants. Defined Benefit Plans We sponsor two frozen defined benefit pension plans ("the Plans"), one in the United Kingdom ("UK") for former employees on an expired customer contract and another assumed as a result of the Gibbs & Cox acquisition. On May 20, 2022, the trustee of our UK defined benefit pension plan (the “Plan”) invested the assets of the Plan in a bulk purchase annuity policy to fully insure the benefits payable to the members of the Plan. As the buy-in transaction insured the defined benefit obligation, we do not anticipate material future contributions. The bulk purchase annuity policy is structured to enable the Plan to move to a full buy-out, at which time the insurer would become directly responsible for all pension payments and we would be relieved of our obligations under the Plan. At this future date, a settlement loss will be recognized for an amount equal to any unamortized loss associated with the Plan recorded within AOCI and any remaining net plan assets of the Plan will be remitted to the Company. As of December 30, 2022, the unamortized loss within AOCI related to the Plan was $20 million and the Plan had net assets of $7 million. The projected benefit obligation of the Plans as of December 30, 2022 and December 31, 2021, was $101 million and $160 million, respectively. The decrease in the projected benefit obligation was primarily due to assumption changes and an actuarial gain. The fair value of the Plans assets as of December 30, 2022, and December 31, 2021, was $101 million and $189 million, respectively. The decrease was primarily driven by assumption changes to reflect the fair value of the annuity contract and return on plan assets. The UK Plan funding status was overfunded $7 million and $37 million as of December 30, 2022, and December 31, 2021, respectively. The Gibbs & Cox defined benefit pension plan funding status was underfunded $7 million and $8 million as of December 30, 2022, and December 31, 2021, respectively. The fair value of Plans assets has been included within "Other long-term liabilities" on the consolidated balance sheets. Other We also sponsor multiemployer defined benefit pension plans and a defined contribution plan (a 401(k) plan) (the "Sponsored Plans") for employees working on two U.S. government contracts. As part of the contractual agreements, the customers reimburse Leidos for contributions made to these Sponsored Plans as these costs are allowable under government contract cost accounting requirements. If we were to cease being the contractor as a result of a recompetition process, the defined benefit pension plans and related plan assets and liabilities would transfer to the new contractor. If the contract expires or is terminated with no transfer of the pension plan to a successor contractor, any amount by which the plan liabilities exceed plan assets, as of that date, will be reimbursed by the U.S. government customer. Since we are not responsible for the current or future funded status of the pension plans, no assets or liabilities arising from their funded status are recorded in the consolidated financial statements and no amounts associated with these pension plans are included in the defined benefit plan disclosures above.

Segment Reporting [Abstract]

Business Segments

Note 20—Business Segments

Our operations and reportable segments are organized around the customers and markets we serve. We define our reportable segments based on the way the chief operating decision maker ("CODM"), currently the Chairman and Chief Executive Officer, manages the operations for purposes of allocating resources and assessing performance.

Our business is aligned into three reportable segments (Defense Solutions, Civil and Health). Additionally, we separately present the unallocable costs associated with corporate functions as Corporate.

Effective July 3, 2021, certain contracts were reassigned from the Defense Solutions reportable segment to the Civil reportable segment. Impact on prior year segment results were determined to be immaterial and have not been recast to reflect this change.

Defense Solutions provides leading-edge and technologically advanced services, solutions and products to a broad customer base. Our ever-changing technologies and innovations cover a wide spectrum of markets with primary areas of concentration in digital modernization, mission systems and integration, Command, Control, Computers, Communications, Intelligence, Surveillance and Reconnaissance ("C4ISR") technologies and services, maritime solutions, transformative software, analytics, intelligence analysis, mission support and logistics services, weapons systems and space systems and solutions. We are dedicated to delivering cost-effective solutions backed by innovation-generating research and development to meet the evolving missions of our customers. We provide a diverse portfolio of national security solutions and systems for air, land, sea, space and cyberspace for the U.S. Intelligence Community, the DoD, the Space Development Agency, the National Aeronautics and Space Administration, Defense Information Systems Agency, military services, government agencies of U.S. allies abroad and other federal and commercial customers in the national security industry. We are heavily engaged in the top defense Research Development Test and Evaluation priorities that are driven by critical evolving threat-driven needs. Our solutions deliver innovative technology, large-scale systems, command and control platforms, data analytics, logistics and cybersecurity solutions, as well as intelligence analysis and operations support to critical missions around the world.

Our Civil business is focused on modernizing infrastructure, systems and security for government and commercial customers both domestically and internationally. By applying leading science, innovative technologies and business acumen, our talented employees help customers achieve their missions and take on the connected world with data-driven insights, improved efficiencies and technological advantages in the areas of digital modernization, energy infrastructure, integrated missions, transportation applications and security detection.

Our Health business focuses on delivering effective and affordable solutions to federal and commercial customers that are responsible for the health and well-being of people worldwide, including service members and veterans. Our solutions enable customers to deliver on the health mission of providing high-quality, cost-effective care, and are accomplished through the integration of information technology, engineering, life sciences, health services, clinical insights and health policy. The capabilities we provide predominantly fall in four major areas of activity: health information management services, managed health services, digital modernization and life sciences research and development.

Corporate includes the operations of various corporate activities, certain corporate expense items that are not reimbursed by our U.S. government customers and certain other expense items excluded from a reportable segment's performance.

The following table summarizes business segment information for the periods presented:


	Year Ended
	December 30, 2022		December 31, 2021		January 1, 2021
	(in millions)
Revenues:
Defense Solutions	$	8,244	$	8,032	$	7,341
Civil	3,464		3,157		2,994
Health	2,688		2,548		1,962
Total revenues	$	14,396	$	13,737	$	12,297

Operating income (loss):
Defense Solutions	$	541	$	569	$	506
Civil	234		248		280
Health	421		442		235
Corporate	(108)		(107)		(23)
Total operating income	$	1,088	$	1,152	$	998

Amortization of intangible assets:
Defense Solutions	$	130	$	121	$	92
Civil	70		73		66
Health	30		34		40
Total amortization of intangible assets	$	230	$	228	$	198

The income statement performance measures used to evaluate segment performance are revenues and operating income. As a result, "Interest expense, net," "Other expense, net," and "Income tax expense," as reported in the consolidated financial statements are not allocated to our segments. Under U.S. government Cost Accounting Standards, indirect costs including depreciation expense are collected in indirect cost pools, which are then collectively allocated out to the reportable segments based on a representative causal or beneficial relationship of the costs in the pool to the costs in the base. While depreciation expense is a component of the allocated costs, the allocation process precludes depreciation expense from being specifically identified by the individual reportable segments. For this reason, depreciation expense by reportable segment has not been reported above.

Asset information by segment is not a key measure of performance used by the CODM.

We generated approximately 86% of our total revenues in fiscal 2022, and 87% in fiscal 2021 and 2020 from contracts with the U.S. government, either as a prime contractor or a subcontractor to other contractors engaged in work for the U.S. government. Revenues under contracts with the DoD and U.S. Intelligence Community, including subcontracts under which the DoD or the U.S. Intelligence Community is the ultimate purchaser, represented approximately 44% of our total revenues for fiscal 2022, 44% for fiscal 2021 and 49% for fiscal 2020.

Approximately 8% of our revenues and tangible long-lived assets are generated by or owned by entities outside of the United States. As such, additional financial information by geographic location is not presented.

- Definition

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

We are involved in various claims and lawsuits arising in the normal conduct of our business, none of which, in the opinion of management, based upon current information, will likely have a material adverse effect on our financial position, results of operations or cash flows.

Contingencies

VirnetX, Inc. ("VirnetX")

On April 10, 2018, a jury trial concluded in an additional patent infringement case brought by VirnetX against Apple, referred to as the Apple II case, in which the jury returned a verdict against Apple for infringement and awarded VirnetX damages in the amount of over $502 million. On April 11, 2018, in a second phase of the Apple II trial, the jury found Apple's infringement to be willful. On August 30, 2018, the federal trial court in the Eastern District of Texas entered a final judgment and rulings on post-trial motions in the Apple II case. The court affirmed the jury’s verdict of over $502 million and granted VirnetX’s motions for supplemental damages, a sunset royalty and royalty rate of $1.20 per infringing device, along with pre-judgment and post-judgment interest and costs. The court denied VirnetX’s motions for enhanced damages, attorneys’ fees and an injunction. The court also denied Apple’s motions for judgment as a matter of law and for a new trial. An additional sum of over $93 million for costs and pre-judgment interest was subsequently agreed upon pursuant to a court order, bringing the total award to VirnetX in the Apple II case to over $595 million. Apple filed an appeal of the judgment in the Apple II case with the U.S. Court of Appeals for the Federal Circuit, and on November 22, 2019, the Federal Circuit affirmed in part, reversed in part and remanded the Apple II case back to the District Court. The Federal Circuit affirmed that Apple infringed two of the patents at issue in the case, and ruled that Apple is precluded from making certain patent invalidity arguments. However, the Federal Circuit reversed the judgment that Apple infringed two other patents at issue, vacated the prior damages awarded in the Apple II case, and remanded the Apple II case back to the District Court for further proceedings regarding damages. On April 23, 2020, the District Court ordered a new trial on damages in the Apple II case, which was delayed by the coronavirus pandemic and started on October 26, 2020. On October 30, 2020, the jury awarded VirnetX $503 million in damages and specified a royalty rate of $0.84 per infringing device. In January 2021, the District Court entered final judgment affirming the jury award and the parties separately agreed on additional costs and interest of over $75 million, subject to Apple's appeal. On February 4, 2021, Apple filed a notice of appeal with the U.S. Court of Appeals for the Federal Circuit in the Apple II case.

Under our agreements with VirnetX, Leidos would receive 25% of the proceeds obtained by VirnetX after reduction for attorneys' fees and costs. However, the verdict in the Apple II case remains subject to the ongoing and potential future proceedings and appeals. In addition, the patents at issue in these cases are subject to U.S. Patent and Trademark Office post-grant inter partes review and/or reexamination proceedings and related appeals, which may result in all or part of these patents being invalidated or the claims of the patents being limited. Thus, no assurances can be given when or if we will receive any proceeds in connection with these jury awards. In addition, if Leidos receives any proceeds, we are required to pay a royalty to the customer who paid for the development of the technology.

Government Investigations and Reviews

We are routinely subject to investigations and reviews relating to compliance with various laws and regulations with respect to our role as a contractor to federal, state and local government customers and in connection with performing services in countries outside of the United States. Adverse findings could have a material effect on our business, financial position, results of operations and cash flows due to our reliance on government contracts.

Defense Contract Audit Agency

As of December 30, 2022, active indirect cost audits by the DCAA remain open for fiscal 2021 and subsequent fiscal years. Although we have recorded contract revenues based upon an estimate of costs that we believe will be approved upon final audit or review, we cannot predict the outcome of any ongoing or future audits or reviews and adjustments and, if future adjustments exceed estimates, our profitability may be adversely affected. As of December 30, 2022, we believe we have adequately reserved for potential adjustments from audits or reviews of contract costs.

Other Government Investigations and Reviews

Through its internal processes, the Company discovered, in late 2021, activities by its employees, third party representatives and subcontractors, raising concerns related to a portion of our business that conducts international operations. The Company is conducting an internal investigation, overseen by an independent committee of the Board of Directors, with the assistance of external legal counsel, to determine whether the identified conduct may have violated the Company’s Code of Conduct and potentially applicable laws, including the U.S. Foreign Corrupt Practices Act ("FCPA"). The Company has voluntarily self-reported this investigation to the Department of Justice and the Securities and Exchange Commission and is cooperating with both agencies. Because the investigation is ongoing, the Company cannot anticipate the timing, outcome or possible impact of the investigation, although violations of the FCPA and other applicable laws may result in criminal and civil sanctions, including monetary penalties, and reputational damage. In September 2022, the Company received a Federal Grand Jury Subpoena related to the criminal investigation by the U.S. Attorney’s Office for the Southern District of California, in conjunction with the U.S. Department of Justice’s Fraud Section. The subpoena requests documents relating to the conduct that is the subject of the Company’s internal investigation. The Company is in the process of responding to the subpoena.

In August 2022, the Company received a Federal Grand Jury Subpoena in connection with a criminal investigation being conducted by the U.S. Department of Justice Antitrust Division (“DOJ”). The subpoena requests that the Company produce a broad range of documents related to three U.S. Government procurements associated with the Company’s Intelligence Group in 2021 and 2022. We intend to fully cooperate with the investigation, and we are conducting our own internal investigation with the assistance of outside counsel. It is not possible at this time to determine whether we will incur, or to reasonably estimate the amount of, any fines, penalties, or further liabilities in connection with the investigation pursuant to which the subpoena was issued.

Commitments

We have outstanding letters of credit of $72 million as of December 30, 2022, principally related to performance guarantees on contracts. We also have outstanding surety bonds with a notional amount of $100 million as of December 30, 2022, principally related to performance and subcontractor payment bonds on contracts. The value of the surety bonds may vary due to changes in the underlying project status and/or contractual modifications. We also have future lease commitments of $74 million for the use of certain aircraft.

As of December 30, 2022, the future expirations of the outstanding letters of credit, surety bonds and future lease commitments were as follows:

Accounting Standards Updates Adopted and Updates Issued But Not Yet Adopted

Accounting Standards Updates Adopted

ASU 2021-08, Business Combinations (Topic 805)

In October 2021, the FASB issued ASU 2021-08, which amends how contract assets and liabilities acquired in a business combination are measured. Current guidance requires contract assets and liabilities to be measured at fair value in accordance with ASC 805, Business Combinations. The amendments in this Update remove the requirement to measure contract assets and liabilities at fair value and instead require that they be recognized in accordance with ASC 606, Revenue from Contracts with Customers.

We adopted the requirements of ASU 2021-08 using the prospective method effective the first day of fiscal 2022. For business combinations occurring after adoption, we measured contract assets and liabilities acquired in accordance ASC 606.

Accounting Standards Updates Issued But Not Yet Adopted

ASU 2020-04, ASU 2021-01, and ASU 2022-06 Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, which provides companies with optional expedients and exceptions to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. This update provides optional expedients for applying accounting guidance to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of the reference rate reform. The amendments in this update are effective for all entities as of March 2020 and can be adopted using a prospective approach no later than December 31, 2022.

In January 2021, the FASB issued ASU 2021-01 which amends the scope of ASU 2020-04. The amendments in this

update are elective and provide optional relief for entities with hedge accounting and contract modifications affected

by the discounting transition through December 31, 2022. In December 2022, the FASB issued ASU 2022-06 which extends the deadline for application of ASU 2021-01 through December 31, 2024. Under this relief, entities may continue to account for contract modifications as a continuation of the existing contract and the continuation of the hedge accounting arrangement. We are currently evaluating the impacts of the reference rate reform. Except for our new $380 million term loan entered into on May 6, 2022 (see "Note 13—Debt"), we currently use the one-month LIBOR for which the rate publication will cease in June 2023.

Reporting Periods

Leidos' fiscal year ends on the Friday nearest the end of December. Fiscal 2022 ended December 30, 2022. Fiscal 2022, 2021 and 2020 each included 52 weeks.

Use of Estimates

Use of EstimatesThe preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Management evaluates these estimates and assumptions on an ongoing basis, including those relating to estimated profitability of long-term contracts, indirect billing rates, allowances for doubtful accounts, inventories, right-of-use ("ROU") assets and lease liabilities, fair value and impairment of intangible assets and goodwill, income taxes, pension benefits, stock-based compensation expense and contingencies. These estimates have been prepared by management on the basis of the most current and best available information; however, actual results could differ materially from those estimates.

Operating Cycle

Operating CycleOur operating cycle for long-term contracts may be greater than one year and is measured by the average time intervening between the inception and the completion of those contracts.

Business Combinations

Business CombinationsThe accounting for business combinations requires management to make judgments and estimates related to the fair value of assets acquired, including the identification and valuation of intangible assets, as well as liabilities and contingencies assumed. Such judgments and estimates directly impact the amount of goodwill recognized in connection with an acquisition. Estimating the fair value of acquired assets and assumed liabilities, including intangibles, requires judgments about expected future cash flows, weighted-average cost of capital, discount rates and expected long-term growth rates.

Investments

Variable Interest Entities

Divestitures

DivestituresFrom time-to-time, we may dispose (or management may commit to plans to dispose) of strategic or non-strategic components of the business. Divestitures representing a strategic shift that has (or will have) a major effect in operations and financial results are classified as discontinued operations, whereas non-strategic divestitures remain in continuing operations.

Restructuring Expenses

Revenue Recognition

Contract Costs

Pre-contract Costs

Transition Costs

Project Assets

Changes in Estimates on Contracts

The impact on diluted earnings per share ("EPS") attributable to Leidos common stockholders is calculated using our statutory tax rate.The changes primarily relate to revisions of variable consideration, including award and incentive fees, and revisions to estimates at completion resulting from changes in contract scope, mitigation of contract risks or due to true-ups of contract estimates at the end of contract performance.

Selling, General and Administrative Expenses

Selling, general and administrative expenses include general and administrative, bid and proposal, company-funded research and development expenses, and legal fees and settlements.

Income Taxes

Cash and Cash Equivalents

Cash and Cash EquivalentsOur cash equivalents are primarily comprised of investments in several large institutional money market accounts, with original maturity of three months or less. Outstanding payments are included within "Cash and cash equivalents" and "Accounts payable and accrued liabilities" correspondingly on the consolidated balance sheets.

Restricted Cash

Receivables

When events or conditions indicate that amounts outstanding from customers may become uncollectible, an allowance is estimated and recorded.

Fair Value Measurements

The fair value of financial instruments is determined based on quoted market prices, if available, or management's best estimate (see "Financial Instruments" below).

Management evaluates its investments for other-than-temporary impairment at each balance sheet date. When testing long-term investments for recovery of carrying value, the fair value of long-term investments is determined using various valuation techniques and factors, such as market prices of comparable companies (Level 2 input), discounted cash flow models (Level 3 input). If management determines that an other-than-temporary decline in the fair value of an investment has occurred, an impairment loss is recognized to reduce the investment to its estimated fair value. Our non-financial instruments measured at fair value on a non-recurring basis include goodwill, indefinite-lived intangible assets and long-lived tangible assets. The valuation methods used to determine fair value require a significant degree of management judgment to determine the key assumptions. As such, we generally classify non-financial instruments as either Level 2 or Level 3 fair value measurements.
