NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1–Basis of Presentation and Summary of Significant Accounting Policies

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® science, engineering and information technology 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 as well as foreign government agencies. 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 a controlling interest in Mission Support Alliance, LLC ("MSA"), a joint venture with Centerra Group, LLC. We also have a 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. The financial results for MSA and HMIS are consolidated into our unaudited condensed consolidated financial statements. The unaudited condensed 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 unaudited condensed consolidated financial statements for the periods presented. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation.

The accompanying unaudited condensed financial information has been prepared in accordance with the rules of the U.S. Securities and Exchange Commission and accounting principles generally accepted in the United States of America ("GAAP"). Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules. The preparation of financial statements in conformity with 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 assets and lease liabilities, fair value and impairment of intangible assets and goodwill, income taxes, 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.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which consist of normal recurring adjustments, necessary for a fair presentation thereof. The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K filed on February 23, 2021.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Accounting Standards Updates ("ASU") Adopted

ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity's Own Equity (Subtopic 815-40)

In August 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-06 which simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separate embedded conversion features from the host convertible instruments. Additionally, the amendments in this update simplify the guidance in Subtopic 815-40 by removing certain criteria that must be satisfied in order to classify a contract as equity. This update also improves the consistency of earnings per share calculations by requiring an entity to use the if-converted method of calculating diluted earnings per share rather than the treasury stock method for convertible instruments and also by requiring the inclusion of the potential effect of shares settled in cash or shares in the diluted earnings per share calculation. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2021, and adopted using either a fully or modified retrospective approach. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. Entities should adopt the guidance as of the beginning of the fiscal year of adoption and cannot adopt the guidance in an interim reporting period.

Effective January 2, 2021, we adopted the requirements of ASU 2020-06 using the modified retrospective method. The adoption did not have an impact to our financial position, results of operations and earnings per share.

ASU 2021-05, Leases (Topic 842) Lessors—Certain Leases with Variable Lease Payments

In July 2021, the FASB issued ASU 2021-05, which amends lessor’s accounting for leases with variable lease payments classified as sales-type or direct financing leases. The amendments in this update modify the lease classification requirements for lessors, whereby leases with variable lease payments that are not dependent on a reference index or a rate will be accounted for as operating leases if classification as a sales-type or direct financing lease would have resulted in a day-one loss. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2021, as well as interim periods within those fiscal years, and can be adopted using either a prospective or retrospective approach. Early adoption is also permitted.

Effective July 3, 2021, we adopted the requirements of ASU 2021-05 using the prospective method. The adoption did not have an impact to our financial position, results of operations and earnings per share.

Accounting Standards Updates Issued But Not Yet Adopted

ASU 2020-04 and ASU 2021-01, Reference Rate Reform (Topic 848)

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. 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 reference rate reform. We currently use the one-month LIBOR for which the rate publication will cease in June 2023.

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.

LEIDOS HOLDINGS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Changes in estimates on contracts were as follows:

	Three Months Ended				Nine Months Ended
	October 1, 2021		October 2, 2020		October 1, 2021		October 2, 2020
	(in millions, except per share amounts)
Favorable impact	$	47	34		$	115	$	86
Unfavorable impact	(24)		(19)		(72)		(45)
Net impact to income before income taxes	$	23	$	15	$	43	$	41
Impact on diluted EPS attributable to Leidos common stockholders	$	0.12	$	0.07	$	0.22	$	0.21

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

Revenue Recognized from Prior Obligations

Revenue recognized from performance obligations satisfied in previous periods was $17 million and $35 million for the three and nine months ended October 1, 2021, respectively, and $10 million and $42 million for the three and nine months ended October 2, 2020, respectively. The changes primarily related 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 true-ups of contract estimates at the end of contract performance.

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. At October 1, 2021 and January 1, 2021, $180 million and $237 million, respectively, of outstanding payments were included within "Cash and cash equivalents" and "Accounts payable and accrued liabilities" correspondingly on the condensed consolidated balance sheets.

Restricted Cash

We have restricted cash balances, primarily representing advances from customers that are restricted for use on certain expenditures related to that customer's contract. Restricted cash balances are included as "Other current assets" in the condensed consolidated balance sheets. Our restricted cash balances were $184 million and $163 million at October 1, 2021 and January 1, 2021, respectively.

Note 2–Revenues from Contracts with Customers

Remaining Performance Obligations

Remaining performance obligations ("RPO") represent the expected value of exercised contracts, both funded and unfunded, less revenue recognized to date. Remaining performance obligations do not include unexercised option periods and future potential task orders expected to be awarded under indefinite delivery/indefinite quantity ("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 October 1, 2021, we had $14.6 billion of RPO and expect to recognize approximately 54% and 71% over the next 12 months and 24 months, respectively, with the remainder to be recognized thereafter.

Disaggregation of Revenues

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	October 1, 2021		January 1, 2021
		(in millions)
Contract assets - current:
Unbilled receivables	Receivables, net	$	1,028	$	906
Contract liabilities - current:
Deferred revenue (1)	Accounts payable and accrued liabilities	$	413	$	481
Contract liabilities - non-current:
Deferred revenue (1)	Other long-term liabilities	$	21	$	20

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

The increase in unbilled receivables was primarily due to revenue recognized on certain contracts partially offset by the timing of billings. The decrease in deferred revenue was primarily due to the timing of advance payments and revenue recognized during the period.

Note 4–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 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 financial instruments measured at fair value on a recurring basis primarily consisted of the following:

	October 1, 2021				January 1, 2021
	Carrying value		Fair value		Carrying value		Fair value
	(in millions)
Financial liabilities:
Derivatives	$	70	$	70	$	103	$	103

As of October 1, 2021, our derivatives primarily consisted of the cash flow interest rate swaps on $1.1 billion of the variable rate senior unsecured term loan (see "Note 5–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 and the underlying interest rate (Level 2 inputs).

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 $15 million as of October 1, 2021, and January 1, 2021, approximates fair value as the stated interest rates within the agreements are consistent with current market rates used in notes with similar terms in the market (Level 2 inputs).

As of October 1, 2021, and January 1, 2021, the fair value of debt was $5.5 billion and $5.2 billion, respectively, and the carrying amount was $5.1 billion and $4.7 billion, respectively (see "Note 6–Debt"). The fair value of long-term 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 May 7, 2021, January 14, 2021, May 4, 2020 and January 31, 2020, non-financial instruments measured at fair value on a non-recurring basis were recorded in connection with the acquisitions of Gibbs & Cox, 1901 Group, SD&A Businesses and Dynetics, respectively (see "Note 3–Acquisitions, Goodwill and Intangible Assets"). The fair values of the assets acquired and liabilities assumed were determined using Level 3 inputs. As of October 1, 2021, we did not have any assets or liabilities measured at fair value on a non-recurring basis.

Note 5–Derivative Instruments

We manage our risk to changes in interest rates through the use of derivative instruments. We do not hold derivative instruments for trading or speculative purposes. 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 the interest rate swaps was as follows:

	Liability derivatives
	Balance sheet line item	October 1, 2021		January 1, 2021
		(in millions)
Cash flow interest rate swaps	Other long-term liabilities	$	70	$	103

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

Cash Flow Hedges

We have interest rate swap agreements to hedge the cash flows of $1.1 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 will receive monthly variable interest payments based on the one-month LIBOR rate and will pay interest at a fixed rate.

The interest rate swap transactions were accounted for as cash flow hedges. The gain/loss on the swaps 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:

	Three Months Ended				Nine Months Ended
	October 1, 2021		October 2, 2020		October 1, 2021		October 2, 2020

Amount recognized in other comprehensive income (loss)	$	—	$	—	$	9	$	(62)
Amount reclassified from accumulated other comprehensive income (loss) to interest expense, net	$	5	$	5	$	14	$	9

We expect to reclassify net losses of $23 million from accumulated other comprehensive loss into earnings during the next 12 months.

Term Loans and Revolving Credit Facility

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").

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%. Principal payments are made quarterly on the Term Loan Facility, with the majority of the principal due at maturity. Interest on the Term Loan Facility for LIBOR-denominated borrowings is payable on a periodic basis, which must be at least quarterly.

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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

On May 7, 2021, we entered into a Credit Agreement (the "2021 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 2021 Credit Agreement date. The proceeds were used to fund the acquisition of Gibbs & Cox.

Borrowings under the 2021 Credit Agreement bear interest at a rate determined, at our option, based on either an alternate base rate plus 0.13% or a LIBOR rate plus 1.13%.

The financial covenants in the 2021 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 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.

The senior unsecured term loans, notes and revolving credit facility 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 October 1, 2021.

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 October 1, 2021, we did not have any Commercial Paper Notes outstanding.

The Commercial Paper Notes will be fully and unconditionally guaranteed by an intercompany guarantee and contains certain customary restrictive covenants.

Note 9–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 our Chairman and Chief Executive Officer, manages operations for the purposes of allocating resources and assessing performance.

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.

The segment information for the periods presented was as follows:

	Three Months Ended				Nine Months Ended
	October 1, 2021		October 2, 2020		October 1, 2021		October 2, 2020
	(in millions)
Revenues:
Defense Solutions	$	2,009	$	1,951	$	5,971	$	5,413
Civil	792		771		2,357		2,183
Health	682		520		1,918		1,449
Total revenues	$	3,483	$	3,242	$	10,246	$	9,045
Operating income (loss):
Defense Solutions	$	140	$	145	$	429	$	359
Civil	58		54		187		191
Health	130		75		339		149
Corporate	(23)		(16)		(73)		—
Total operating income	$	305	$	258	$	882	$	699

The income statement performance measures used to evaluate segment performance are revenues and operating income. As a result, "Interest expense, net," "Other income (expense), net" and "Income tax expense" as reported in the condensed consolidated statements of income 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 to the reportable segments based on a representative causal or beneficial relationship of the costs in the pool to the costs in the base. As such, depreciation expense is not separately disclosed on the condensed consolidated statements of income.

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

Legal Proceedings

Class Action Lawsuit

On March 2, 2021, Leidos and certain current officers of Leidos were named as defendants in a putative class action securities lawsuit filed in the U.S. District Court for the Southern District of New York. The complaint alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder relating to alleged misstatements or omissions in Leidos' public filings with the SEC and other public statements during the period from May 4, 2020 to February 23, 2021 relating, among other things, to Leidos' acquisition of the SD&A Businesses. The plaintiff sought to recover from the Company and the individual defendants an unspecified amount of damages at this time. On July 30, 2021, the District Court appointed a lead plaintiff and lead counsel. On September 28, 2021, the lead plaintiff voluntarily dismissed the action without prejudice.

Other 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.

As of October 1, 2021, indirect cost active audits by the Defense Contract Audit Agency remain open for fiscal 2016 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 October 1, 2021, we believe we have adequately reserved for potential adjustments from audits or reviews of contract costs.

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

The following discussion and analysis of Leidos Holdings, Inc.'s ("Leidos") financial condition, results of operations, and quantitative and qualitative discussion about business environment and trends should be read in conjunction with Leidos' condensed consolidated financial statements and related notes.

The following discussion contains forward-looking statements, including statements regarding our intent, belief or current expectations with respect to, among other things, trends affecting our financial condition or results of operations, backlog, our industry, the impact of our merger and acquisition activity, government budgets and spending, our business contingency plans, uncertainties in tax due to new tax legislation or other regulatory developments and our ability to recover certain costs through the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). Such statements are not guarantees of future performance and involve risks and uncertainties, including uncertainties relating to the coronavirus pandemic ("COVID-19") and the actions taken by authorities and us to respond, and actual results may differ materially from those in the forward-looking statements as a result of various factors. Some of these factors include, but are not limited to, the risk factors set forth in our Annual Report on Form 10-K, as updated by the risk factor in this report under Part II, Item 1A. "Risk Factors" and as may be further updated in subsequent filings with the U.S. Securities and Exchange Commission. Due to such uncertainties and risks, you are cautioned not to place undue reliance on such forward-looking statements, which speak only as of the date hereof. We do not undertake any obligation to update these factors or to publicly announce the results of any changes to our forward-looking statements due to future events or developments.

Unless indicated otherwise, references in this report to "we," "us" and "our" refer collectively to Leidos and its consolidated subsidiaries.

Overview

We are a FORTUNE 500® science, engineering and information technology company that provides services and solutions in the defense, intelligence, civil and health markets, both domestically and internationally. We bring domain-specific capability and cross-market innovations to customers in each of these markets by leveraging five technical core competencies: digital modernization, cyber operations, mission software systems, integrated systems and mission operations. Our 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 as well as foreign government agencies. We operate in three reportable segments: Defense Solutions, Civil and Health. Additionally, we separately present the unallocable costs associated with corporate functions as Corporate.

COVID-19

For the three and nine months ended October 1, 2021, COVID-19 did not have a material impact to revenues and operating income. The full extent of the impact of the COVID-19 pandemic on our operational and financial performance, including our ability to execute on programs in the expected timeframe, will depend on future developments, including the duration and spread of the pandemic and the distribution of vaccines, all of which are uncertain and cannot be predicted.

Section 3610 of the CARES Act, a $2 trillion coronavirus response bill providing widespread emergency relief, authorized the government to reimburse qualifying contractors for the cost of certain impacts of COVID-19. While a portion of the recoveries that we have made are a result of Section 3610 of the CARES Act, the Act expired on September 30, 2021.

Effective October 1, 2021, we mandated a policy requiring all employees, vendors, subcontractors and visitors to be vaccinated or maintain proof of a negative COVID-19 test in order to enter a Leidos facility in the U.S. or to attend company business events outside of our facilities.

On September 9, 2021, President Biden issued a series of executive orders to combat COVID-19, which requires us, as a federal contractor, to ensure that all of our employees are fully vaccinated by December 8, 2021, unless the employee is legally entitled to a religious or medical exemption. We are currently assessing the impact our policy will have on our workforce and operations.

Business Environment and Trends

U.S. Government Markets

During the three and nine months ended October 1, 2021, we generated approximately 88% and 87%, respectively, of our total revenues from contracts with the U.S. government. Accordingly, our business performance is affected by the overall level of U.S. government spending, especially on national security, homeland security and intelligence, and the alignment of our service and product offerings and capabilities with current and future budget priorities of the U.S. government.

Congress received the GFY 2022 President’s Budget Request on May 28, 2021 and passed a Continuing Resolution ("CR") before the GFY deadline of September 30, 2021. The CR will fully fund the federal government at current levels through December 3, 2021 and provides $28.6 billion in disaster relief and $6.3 billion to support Afghanistan evacuees. The House and Senate also voted to extend the debt limit waiver through December 3, 2021.

International Markets

Sales to customers in international markets represented approximately 8% of total revenues for the three and nine months ended October 1, 2021. Our international customers include foreign governments and their agencies. Our international business increases our exposure to international markets and the associated international regulatory and geopolitical risks.

Changes in international trade policies, including higher tariffs on imported goods and materials, may increase our procurement costs of certain IT hardware used both on our contracts and for internal use. However, we expect to recover certain portions of these higher tariffs through our cost-plus contracts. While we evaluate the impact of higher tariffs, currently, we do not expect tariffs to have a significant impact to our business.

The increase in revenues for the three months ended October 1, 2021, as compared to the three months ended October 2, 2020, was primarily attributable to program wins and $47 million of revenues from the acquisitions of Gibbs & Cox and 1901 Group, partially offset by the completion of contracts and a net decrease in volumes on certain programs.

The increase in revenues for the nine months ended October 1, 2021, as compared to the nine months ended October 2, 2020, was primarily attributable to program wins, a net increase in volumes on certain programs and $97 million of revenues from the acquisitions of Gibbs & Cox and 1901 Group, partially offset by the completion of certain contracts. In addition, for the nine months ended October 1, 2021, there was a $66 million benefit in exchange rate movements.

The decrease in operating income for the three months ended October 1, 2021, as compared to the three months ended October 2, 2020, was primarily attributable to a net decrease in volumes on certain programs and the completion of certain contracts, partially offset by program wins.

The increase in operating income for the nine months ended October 1, 2021, as compared to the nine months ended October 2, 2020, was primarily due to program wins, a net increase in program volumes on certain contracts and the acquisitions of Gibbs & Cox and 1901 Group, partially offset by the completion of certain contracts.

LEIDOS HOLDINGS, INC.

The increase in revenues for the three months ended October 1, 2021, as compared to the three months ended October 2, 2020, was primarily attributable to program wins and a reduction of the negative impacts from COVID-19 experienced during the prior year quarter, partially offset by a net decrease in program volumes.

The increase in revenues for the nine months ended October 1, 2021, as compared to the nine months ended October 2, 2020, was primarily attributable to a net increase of $62 million of revenues related to L3 Harris Technologies' security and detection businesses (the "SD&A Businesses") acquired in the prior year, a net increase in program volumes, program wins and a reduction of the negative impacts from COVID-19 experienced during the prior year.

The increase in operating income for the three months ended October 1, 2021, as compared to the three months ended October 2, 2020, was primarily due to improved performance on certain programs and lower amortization of intangible assets related to the acquisition of the SD&A Businesses, partially offset by fewer product deliveries on certain programs.

The decrease in operating income for the nine months ended October 1, 2021, as compared to the nine months ended October 2, 2020, was primarily attributable to a net decrease in volumes due to the timing of product deliveries on certain programs, partially offset by a $26 million benefit from an adjustment to legal reserves related to the Mission Support Alliance joint venture during the first quarter of fiscal 2021.

The increase in revenues for the three months ended October 1, 2021, as compared to the three months ended October 2, 2020, was primarily attributable to a net increase in volumes on certain programs and program wins.

The increase in revenues for the nine months ended October 1, 2021, as compared to the nine months ended October 2, 2020, was primarily attributable to a net increase in volumes on certain programs, program wins and an approximately $96 million reduction of the negative impacts of COVID-19 experienced during the prior year, partially offset by the completion of certain contracts.

The increase in operating income for the three months ended October 1, 2021, as compared to the three months ended October 2, 2020, was primarily due to increased volume on fixed unit price programs.

The increase in operating income for the nine months ended October 1, 2021, as compared to the nine months ended October 2, 2020, was primarily attributable to a net increase in volumes on higher margin programs, an approximately $63 million reduction of the negative impacts of COVID-19 experienced in the prior year and a net decrease in asset impairment charges of $8 million.

NM - Not Meaningful

The increase in operating loss for the nine months ended October 1, 2021, as compared to the nine months ended October 2, 2020, was primarily attributable to an $81 million net gain recognized during the second quarter of fiscal 2020 upon receipt of proceeds related to the VirnetX, Inc. legal matter and a decrease in acquisition and integration costs.

LEIDOS HOLDINGS, INC.

Non-Operating Expense, net

Non-operating expense, net for the three months ended October 1, 2021 was $45 million, consistent with the three months ended October 2, 2020 of $44 million.

Non-operating expense, net for the nine months ended October 1, 2021 was $137 million as compared to $163 million for the nine months ended October 2, 2020. The change was primarily due to $31 million of debt discount and deferred financing costs written off related to refinancing activities in the prior year.

Provision for Income Taxes

For the three months ended October 1, 2021, our effective tax rate was 20.0% compared to 23.8% for the three months ended October 2, 2020. The decrease in the effective tax rate was primarily due to a decrease in foreign taxes and an increase in research tax credits.

For the nine months ended October 1, 2021, our effective tax rate was 21.7% compared to 19.4% for the nine months ended October 2, 2020. The increase in the effective tax rate was primarily due to a net decrease in benefits related to employee stock-based payments.

Beginning in 2022, the Tax Cuts and Jobs Act of 2017 eliminates the option to currently deduct research and development costs for tax purposes and requires taxpayers to amortize domestic and foreign research costs over five years and 15 years, respectively. The House Ways and Means Committee has proposed tax legislation to delay the effective date of this change to 2026, but it is uncertain whether the proposed delay will ultimately be enacted into law. If the 2022 effective date remains in place, our initial assessment is our cash from operations would materially decrease in 2022 and our net deferred tax assets would increase by a similar amount. We are currently evaluating the potential impact on our cash flows from operations.

Bookings and Backlog

We recorded net bookings worth an estimated $4.7 billion and $12.3 billion during the three and nine months ended October 1, 2021, as compared to $4.3 billion and $14.5 billion for the three and nine months ended October 2, 2020.

The estimated value of our total backlog was as follows:

	October 1, 2021						October 2, 2020
Segment	Funded		Unfunded		Total		Funded		Unfunded		Total
	(in millions)
Defense Solutions	$	4,412	$	15,160	$	19,572	$	4,115	$	13,746	$	17,861
Civil	1,713		7,702		9,415		1,521		7,028		8,549
Health	1,164		4,541		5,705		1,208		4,101		5,309
Total	$	7,289	$	27,403	$	34,692	$	6,844	$	24,875	$	31,719

The increase in backlog includes $757 million of backlog acquired through business combinations in our Defense Solutions reportable segment.

Backlog represents the estimated amount of future revenues to be recognized under negotiated contracts, both funded and unfunded. Backlog does not include unexercised option periods and future potential task orders expected to be awarded under indefinite delivery/indefinite quantity ("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. Total backlog at October 1, 2021 included a positive impact of $103 million when compared to total backlog at October 2, 2020, primarily due to the exchange rate movement in the British pound when compared to the U.S. dollar. Backlog estimates are subject to change and may be affected by factors including modifications of contracts and foreign currency movements.

At October 1, 2021, and January 1, 2021, we had outstanding debt of $5.1 billion and $4.7 billion, respectively. On May 7, 2021, we entered into a Credit Agreement which provided for a senior unsecured term loan facility in an aggregate principal amount of $380 million.

We made principal payments on our long-term debt of $27 million and $80 million during the three and nine months ended October 1, 2021, respectively, and $477 million and $705 million during the three and nine months ended October 2, 2020, respectively. This activity included required principal payments on our term loans of $24 million and $72 million during the three and nine months ended October 1, 2021, and $24 million and $48 million during the three and nine months ended October 2, 2020. During the nine months ended October 2, 2020, we made additional payments of $3,975 million, related to our refinancing activities. On September 1, 2020, we retired our $450 million senior unsecured notes due December 2020.

The senior unsecured term loans and notes contain financial covenants and customary restrictive covenants. We were in compliance with all covenants as of October 1, 2021.

On July 12, 2021, Leidos, Inc. established a commercial paper program in which we may issue short-term unsecured commercial paper notes not to exceed $750 million and have maturities of up to 397 days from the date of issuance (see "Note 6–Debt" ). As of October 1, 2021, we did not have any Commercial Paper Notes outstanding.

We paid dividends of $51 million and $149 million during the three and nine months ended October 1, 2021, respectively, and $49 million and $148 million during the three and nine months ended October 2, 2020, respectively.

During the nine months ended October 1, 2021, we sold $693 million of accounts receivable under accounts receivable purchase agreements. There were no sales of accounts receivable during the thee months ended October 1, 2021. During the three and nine months ended October 2, 2020, we sold $753 million and $1,866 million of accounts receivable under accounts receivable purchase agreements and received proceeds of $752 million and $1,864 million, respectively.

Stock repurchases of Leidos common stock may be made on the open market or in privately negotiated transactions with third parties including through accelerated share repurchase agreements. Whether repurchases are made and the timing and actual number of shares repurchased depends on a variety of factors including price, corporate capital requirements, other market conditions and regulatory requirements. The repurchase program may be accelerated, suspended, delayed or discontinued at any time.

During the three and nine months ended October 1, 2021, we made open market repurchases of our common stock, under the Company's share repurchase program, for an aggregate purchase price of $137 million and $237 million, respectively.

The proposed legislation changes to the Tax Cuts and Jobs Act of 2017 and the potential for COVID-19 to affect the financial markets may impact our liquidity. We will continue to assess our liquidity needs as the proposed tax legislation changes and pandemic evolve.

For the next 12 months, we anticipate that we will be able to meet our liquidity needs, including servicing our debt, through cash generated from operations, available cash balances, sales of accounts receivable and, if needed, borrowings under our revolving credit facility and commercial paper program.

Summary of Cash Flows

The following table summarizes cash flow information for the periods presented:

	Three Months Ended				Nine Months Ended
	October 1, 2021		October 2, 2020		October 1, 2021		October 2, 2020
	(in millions)
Net cash provided by operating activities	$	565	$	592	$	821	$	1,386
Net cash used in investing activities	(53)		(15)		(693)		(2,714)
Net cash (used in) provided by financing activities	(209)		(517)		(44)		1,353
Net increase in cash, cash equivalents and restricted cash	$	303	$	60	$	84	$	25

Net cash provided by operating activities decreased $27 million for the three months ended October 1, 2021, when compared to the prior year quarter. The decrease was primarily due to the $92 million deferral of employer payroll taxes in the prior year and the timing of customer advance payments, partially offset by lower income tax payments of $34 million and other favorable working capital changes.

Net cash provided by operating activities decreased $565 million for the nine months ended October 1, 2021, when compared to the prior year. The decrease was primarily due to lower sales of accounts receivable outstanding of $232 million, $92 million of deferral of employer payroll taxes in the prior year, higher income tax payments of $69 million, the receipt of $85 million of proceeds related to the VirnetX legal matter in the prior year and the timing of customer advance payments.

Net cash used in investing activities increased $38 million for the three months ended October 1, 2021, when compared to the prior year quarter primarily due to an additional inconsequential acquisition made during the current quarter (see "Note 3–Acquisitions, Goodwill and Intangible Assets").

Net cash used in investing activities decreased $2,021 million for the nine months ended October 1, 2021, when compared to the prior year, primarily due to larger acquisitions made in the prior year for Dynetics and the SD&A Businesses compared to our material current year acquisitions, 1901 Group and Gibbs & Cox (see "Note 3–Acquisitions, Goodwill and Intangible Assets") and lower capital expenditures in the current year.

Net cash used in financing activities decreased $308 million for the three months ended October 1, 2021 when compared to the prior year quarter. The change was primarily due to the early repayment to retire our $450 million senior unsecured notes in the prior year quarter, partially offset by $137 million of open market stock repurchases in the current year quarter.

Net cash used in financing activities increased $1,397 million for the nine months ended October 1, 2021, when compared to the prior year. The change was primarily due to a decrease of approximately $1,206 million from the net change of proceeds received from the issuance of debt, principal payments and payments for debt issuance

costs and by $237 million of open market stock repurchases in the current year, partially offset by a net $34 million

increase in capital contributions received from our non-controlling interest.

Off-Balance Sheet Arrangements

We have outstanding performance guarantees and cross-indemnity agreements in connection with certain aspects of our business. We also have letters of credit outstanding principally related to performance guarantees on contracts and surety bonds outstanding principally related to performance and subcontractor payment bonds as described in "Note 10–Commitments and Contingencies" of the notes to the condensed consolidated financial statements contained within this Quarterly Report on Form 10-Q. These arrangements have not had, and management does not believe it is likely that they will in the future have, a material effect on our liquidity, capital resources, operations or financial condition.

There were no material changes in our market risk exposure from those discussed in our Annual Report on Form 10-K for the year ended January 1, 2021.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer (our Chairman and Chief Executive Officer) and principal financial officer (our Executive Vice President and Chief Financial Officer), has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934) as of October 1, 2021. Based upon that evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the U.S. Securities and Exchange Commission. These disclosure controls and procedures include, without

limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

On May 7, 2021 and January 14, 2021, we completed the acquisitions of Gibbs & Cox and 1901 Group, respectively ("the Acquired Businesses"). In conducting our evaluation of the effectiveness of our internal control over financial reporting, we excluded the Acquired Businesses from our evaluation for the third quarter of fiscal 2021. We are in the process of integrating the Acquired Businesses into our system of internal control over financial reporting.

Other than the foregoing, there have been no changes in our internal control over financial reporting that occurred in the quarterly period covered by this report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

We have furnished information relating to legal proceedings, and any investigations and reviews that we are involved with in "Note 10–Commitments and Contingencies" of the notes to the condensed consolidated financial statements contained within this Quarterly Report on Form 10-Q.

Item 1A. Risk Factors.

Other than as described below, there were no material changes to the risks described in Part I, Item 1A "Risk Factors" in our Annual Report on Form 10-K for the year ended January 1, 2021.

The extent to which our business will be adversely affected by COVID-19 or other health epidemics, pandemics and similar outbreaks is highly uncertain and cannot be predicted.

The outbreak and global spread of COVID-19, and the preventative or protective actions that governments, corporations, individuals and we are taking and may continue to take in an effort to limit the impact of COVID-19, have resulted in a period of business disruption and increased economic uncertainty. The spread of COVID-19 has caused us to modify our business practices, including vaccination and testing requirements, employee travel, access to customer sites, employee and contractor remote work and restrictions to physical participation in meetings, events and conferences. We may take further actions that we determine are in the best interests of our employees, customers and business partners or may be required by government authorities. For example, on September 9, 2021, President Biden issued a series of executive orders to combat COVID-19, which requires us, as a federal contractor, to have our employees fully vaccinated by December 8, 2021, unless the employee is legally entitled to a religious or medical exemption. Effective October 1, 2021, we mandated a policy requiring all employees, vendors, subcontractors and visitors to be vaccinated or maintain proof of a negative COVID-19 test in order to enter a Leidos facility in the U.S. or to attend company business events outside of our facilities. On December 8, 2021, in order to comply with the executive orders, we will no longer allow proof of a negative COVID-19 test and all U.S. employees will be required to be vaccinated unless legally entitled to a religious or medical exemption. There is no certainty that such measures will be sufficient to mitigate the risks posed by COVID-19. If significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, increased employee attrition, facility closures or other restrictions due to COVID-19, or do not comply with our vaccination mandate, our business and results of operations could be materially and adversely impacted.

Government agencies are our primary customers and the long-term impact of increased government spending in response to COVID-19 is uncertain. This could result in a re-evaluation of U.S. government spending levels and priorities, which could impact our business performance. The situation surrounding COVID-19 remains fluid and the likelihood of an impact on us that could be material increases the longer the virus impacts activity levels in the locations in which we operate. In particular, the emergence of new and more transmissible COVID-19 variants, including the efficacy of vaccines against such variants, booster vaccinations, or a lack of public acceptance of vaccines and low vaccination rates in certain parts of the U.S., may lead to delays in economic recovery. Further, even if vaccines are widely distributed and accepted, there can be no assurance that vaccines will ultimately be successful in limiting or stopping the spread of COVID-19.

Even after COVID-19 has subsided, we may experience materially adverse impacts on our business as a result of the pandemic's global economic impact, including any recession that is occurring or may occur in the future. For example, the global spread of COVID-19 has resulted in a substantial decline in demand for air travel, which has adversely impacted the demand for products and services related to our airport security detection and automation business. We are not able to predict whether COVID-19 will result in permanent changes to air travel behaviors, including a permanent reduction in business travel as a result of the increased use of teleconferencing products and, more broadly, a general reluctance to travel by consumers, each of which has, and could continue to, impact our business. Further, new contract awards have been and may continue to be delayed and our ability to perform on our existing contracts has been and may continue to be delayed or impaired, which will negatively impact our revenues. In addition, our program costs have increased as a result of COVID-19, and these cost increases may not be fully recoverable or adequately covered by insurance or equitable adjustments to contract prices, which could impact our profitability. The continued spread of COVID-19 has had and may continue to have similar negative impacts on our customers and third parties on which we rely, including subcontractors, service providers, suppliers and other business partners, causing delay or limiting their ability to perform, including in making timely payments to us. Any resulting financial impact cannot be reasonably estimated at this time but may materially and adversely affect our business, financial condition, results of operations and cash flows. The extent to which COVID-19 impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity and duration of COVID-19 and actions to contain it or treat its impact, among others. In addition, to the extent COVID-19 or any worsening of the global business and economic

33

LEIDOS HOLDINGS, INC.

environment as a result adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described herein.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(a)None

(b)None

(c)Purchases of Equity Securities by the Issuer

On February 16, 2018, our Board of Directors authorized a share repurchase program of up to 20 million shares of our outstanding common stock. The shares may be repurchased from time to time in one or more open market repurchases or privately negotiated transactions, including accelerated share repurchase transactions. The actual timing, number and value of shares repurchased under the program will depend on a number of factors, including the market price of our common stock, general market and economic conditions, applicable legal requirements, compliance with the terms of our outstanding indebtedness and other considerations. There is no assurance as to the number of shares that will be repurchased, and the repurchase program may be suspended or discontinued at any time at our Board of Directors' discretion.

Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Note 1–Basis of Presentation and Summary of Significant Accounting Policies

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® science, engineering and information technology 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 as well as foreign government agencies. 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 a controlling interest in Mission Support Alliance, LLC ("MSA"), a joint venture with Centerra Group, LLC. We also have a 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. The financial results for MSA and HMIS are consolidated into our unaudited condensed consolidated financial statements. The unaudited condensed 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 unaudited condensed consolidated financial statements for the periods presented. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation.

The accompanying unaudited condensed financial information has been prepared in accordance with the rules of the U.S. Securities and Exchange Commission and accounting principles generally accepted in the United States of America ("GAAP"). Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules. The preparation of financial statements in conformity with 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 assets and lease liabilities, fair value and impairment of intangible assets and goodwill, income taxes, 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.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which consist of normal recurring adjustments, necessary for a fair presentation thereof. The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K filed on February 23, 2021.

Accounting Standards Updates ("ASU") Adopted

ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity's Own Equity (Subtopic 815-40)

In August 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-06 which simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separate embedded conversion features from the host convertible instruments. Additionally, the amendments in this update simplify the guidance in Subtopic 815-40 by removing certain criteria that must be satisfied in order to classify a contract as equity. This update also improves the consistency of earnings per share calculations by requiring an entity to use the if-converted method of calculating diluted earnings per share rather than the treasury stock method for convertible instruments and also by requiring the inclusion of the potential effect of shares settled in cash or shares in the diluted earnings per share calculation. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2021, and adopted using either a fully or modified retrospective approach. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. Entities should adopt the guidance as of the beginning of the fiscal year of adoption and cannot adopt the guidance in an interim reporting period.

Effective January 2, 2021, we adopted the requirements of ASU 2020-06 using the modified retrospective method. The adoption did not have an impact to our financial position, results of operations and earnings per share.

ASU 2021-05, Leases (Topic 842) Lessors—Certain Leases with Variable Lease Payments

In July 2021, the FASB issued ASU 2021-05, which amends lessor’s accounting for leases with variable lease payments classified as sales-type or direct financing leases. The amendments in this update modify the lease classification requirements for lessors, whereby leases with variable lease payments that are not dependent on a reference index or a rate will be accounted for as operating leases if classification as a sales-type or direct financing lease would have resulted in a day-one loss. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2021, as well as interim periods within those fiscal years, and can be adopted using either a prospective or retrospective approach. Early adoption is also permitted.

Effective July 3, 2021, we adopted the requirements of ASU 2021-05 using the prospective method. The adoption did not have an impact to our financial position, results of operations and earnings per share.

Accounting Standards Updates Issued But Not Yet Adopted

ASU 2020-04 and ASU 2021-01, Reference Rate Reform (Topic 848)

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. 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 reference rate reform. We currently use the one-month LIBOR for which the rate publication will cease in June 2023.

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 were as follows:

	Three Months Ended				Nine Months Ended
	October 1, 2021		October 2, 2020		October 1, 2021		October 2, 2020
	(in millions, except per share amounts)
Favorable impact	$	47	34		$	115	$	86
Unfavorable impact	(24)		(19)		(72)		(45)
Net impact to income before income taxes	$	23	$	15	$	43	$	41
Impact on diluted EPS attributable to Leidos common stockholders	$	0.12	$	0.07	$	0.22	$	0.21

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

Revenue Recognized from Prior Obligations

Revenue recognized from performance obligations satisfied in previous periods was $17 million and $35 million for the three and nine months ended October 1, 2021, respectively, and $10 million and $42 million for the three and nine months ended October 2, 2020, respectively. The changes primarily related 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 true-ups of contract estimates at the end of contract performance.

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. At October 1, 2021 and January 1, 2021, $180 million and $237 million, respectively, of outstanding payments were included within "Cash and cash equivalents" and "Accounts payable and accrued liabilities" correspondingly on the condensed consolidated balance sheets.

Restricted Cash

We have restricted cash balances, primarily representing advances from customers that are restricted for use on certain expenditures related to that customer's contract. Restricted cash balances are included as "Other current assets" in the condensed consolidated balance sheets. Our restricted cash balances were $184 million and $163 million at October 1, 2021 and January 1, 2021, respectively.

Revenues from Contracts with Customers

Revenue from Contract with Customer [Abstract]

Revenues from Contracts with Customers

Note 2–Revenues from Contracts with Customers

Remaining Performance Obligations

Remaining performance obligations ("RPO") represent the expected value of exercised contracts, both funded and unfunded, less revenue recognized to date. Remaining performance obligations do not include unexercised option periods and future potential task orders expected to be awarded under indefinite delivery/indefinite quantity ("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 October 1, 2021, we had $14.6 billion of RPO and expect to recognize approximately 54% and 71% over the next 12 months and 24 months, respectively, with the remainder 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.

Revenues by customer-type, contract-type and geographic location exclude lease income of $34 million and $89 million for the three and nine months ended October 1, 2021, respectively, and $24 million and $71 million for the three and nine months ended October 2, 2020, respectively.

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	October 1, 2021		January 1, 2021
		(in millions)
Contract assets - current:
Unbilled receivables	Receivables, net	$	1,028	$	906
Contract liabilities - current:
Deferred revenue (1)	Accounts payable and accrued liabilities	$	413	$	481
Contract liabilities - non-current:
Deferred revenue (1)	Other long-term liabilities	$	21	$	20

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

The increase in unbilled receivables was primarily due to revenue recognized on certain contracts partially offset by the timing of billings. The decrease in deferred revenue was primarily due to the timing of advance payments and revenue recognized during the period.

Revenue recognized for the three and nine months ended October 1, 2021 of $31 million and $253 million, respectively, was included as a contract liability at January 1, 2021. Revenue recognized for the three and nine months ended October 2, 2020 of $41 million and $267 million, respectively, was included as a contract liability at January 3, 2020.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 4–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 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 financial instruments measured at fair value on a recurring basis primarily consisted of the following:

	October 1, 2021				January 1, 2021
	Carrying value		Fair value		Carrying value		Fair value
	(in millions)
Financial liabilities:
Derivatives	$	70	$	70	$	103	$	103

As of October 1, 2021, our derivatives primarily consisted of the cash flow interest rate swaps on $1.1 billion of the variable rate senior unsecured term loan (see "Note 5–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 and the underlying interest rate (Level 2 inputs).

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 $15 million as of October 1, 2021, and January 1, 2021, approximates fair value as the stated interest rates within the agreements are consistent with current market rates used in notes with similar terms in the market (Level 2 inputs).

As of October 1, 2021, and January 1, 2021, the fair value of debt was $5.5 billion and $5.2 billion, respectively, and the carrying amount was $5.1 billion and $4.7 billion, respectively (see "Note 6–Debt"). The fair value of long-term 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 May 7, 2021, January 14, 2021, May 4, 2020 and January 31, 2020, non-financial instruments measured at fair value on a non-recurring basis were recorded in connection with the acquisitions of Gibbs & Cox, 1901 Group, SD&A Businesses and Dynetics, respectively (see "Note 3–Acquisitions, Goodwill and Intangible Assets"). The fair values of the assets acquired and liabilities assumed were determined using Level 3 inputs. As of October 1, 2021, we did not have any assets or liabilities measured at fair value on a non-recurring basis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Note 5–Derivative Instruments

We manage our risk to changes in interest rates through the use of derivative instruments. We do not hold derivative instruments for trading or speculative purposes. 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 the interest rate swaps was as follows:

	Liability derivatives
	Balance sheet line item	October 1, 2021		January 1, 2021
		(in millions)
Cash flow interest rate swaps	Other long-term liabilities	$	70	$	103

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

Cash Flow Hedges

We have interest rate swap agreements to hedge the cash flows of $1.1 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 will receive monthly variable interest payments based on the one-month LIBOR rate and will pay interest at a fixed rate.

The interest rate swap transactions were accounted for as cash flow hedges. The gain/loss on the swaps 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:

	Three Months Ended				Nine Months Ended
	October 1, 2021		October 2, 2020		October 1, 2021		October 2, 2020
	(in millions)
Total interest expense, net presented in the condensed consolidated statements of income in which the effects of cash flow hedges are recorded	$	47	$	44	$	138	$	133
Amount recognized in other comprehensive income (loss)	$	—	$	—	$	9	$	(62)
Amount reclassified from accumulated other comprehensive income (loss) to interest expense, net	$	5	$	5	$	14	$	9

We expect to reclassify net losses of $23 million from accumulated other comprehensive loss into earnings during the next 12 months.

(2) We filed a Registration Statement on Form S-4 with the Securities and Exchange Commission on May 6, 2021, and was declared effective on May 19, 2021.

Term Loans and Revolving Credit Facility

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").

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%. Principal payments are made quarterly on the Term Loan Facility, with the majority of the principal due at maturity. Interest on the Term Loan Facility for LIBOR-denominated borrowings is payable on a periodic basis, which must be at least quarterly.

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.

On May 7, 2021, we entered into a Credit Agreement (the "2021 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 2021 Credit Agreement date. The proceeds were used to fund the acquisition of Gibbs & Cox.

Borrowings under the 2021 Credit Agreement bear interest at a rate determined, at our option, based on either an alternate base rate plus 0.13% or a LIBOR rate plus 1.13%.

The financial covenants in the 2021 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 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.

The senior unsecured term loans, notes and revolving credit facility 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 October 1, 2021.

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 October 1, 2021, we did not have any Commercial Paper Notes outstanding.

The Commercial Paper Notes will be fully and unconditionally guaranteed by an intercompany guarantee and contains certain customary restrictive covenants.

Principal Payments and Debt Issuance Costs

We made principal payments on our long-term debt of $27 million and $80 million during the three and nine months ended October 1, 2021, respectively, and $477 million and $705 million during the three and nine months ended October 2, 2020, respectively. This activity included required principal payments on our term loans of $24 million and $72 million during the three and nine months ended October 1, 2021, respectively, and $24 million and $48 million for the three and nine months ended October 2, 2020, respectively. During the nine months ended October 2, 2020, we made additional payments of $3,975 million, related to our refinancing activities. Additionally, on September 1, 2020, we retired our $450 million senior unsecured notes due December 2020.

As of October 1, 2021 and January 1, 2021, there were no borrowings outstanding under the Revolving Facility.

For the nine months ended October 2, 2020, $31 million of debt discount and debt issuance costs were written off related to the prior year refinancing activities. Amortization of debt discount and debt issuance costs was $3 million and $7 million for the three and nine months ended October 1, 2021, respectively, and $4 million and $13 million for the three and nine months ended October 2, 2020, respectively.

The total outstanding stock options and vesting stock awards that were anti-dilutive were 1 million for both the three and nine months ended October 1, 2021, and the three and nine months ended October 2, 2020.

During the three and nine months ended October 1, 2021, we made open market repurchases of our common stock for an aggregate purchase price of $137 million and $237 million, respectively. All shares repurchased were immediately retired.

Segment Reporting [Abstract]

Business Segments

Note 9–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 our Chairman and Chief Executive Officer, manages operations for the purposes of allocating resources and assessing performance.

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.

The segment information for the periods presented was as follows:

	Three Months Ended				Nine Months Ended
	October 1, 2021		October 2, 2020		October 1, 2021		October 2, 2020
	(in millions)
Revenues:
Defense Solutions	$	2,009	$	1,951	$	5,971	$	5,413
Civil	792		771		2,357		2,183
Health	682		520		1,918		1,449
Total revenues	$	3,483	$	3,242	$	10,246	$	9,045
Operating income (loss):
Defense Solutions	$	140	$	145	$	429	$	359
Civil	58		54		187		191
Health	130		75		339		149
Corporate	(23)		(16)		(73)		—
Total operating income	$	305	$	258	$	882	$	699

The income statement performance measures used to evaluate segment performance are revenues and operating income. As a result, "Interest expense, net," "Other income (expense), net" and "Income tax expense" as reported in the condensed consolidated statements of income 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 to the reportable segments based on a representative causal or beneficial relationship of the costs in the pool to the costs in the base. As such, depreciation expense is not separately disclosed on the condensed consolidated statements of income.

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

Legal Proceedings

Class Action Lawsuit

On March 2, 2021, Leidos and certain current officers of Leidos were named as defendants in a putative class action securities lawsuit filed in the U.S. District Court for the Southern District of New York. The complaint alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder relating to alleged misstatements or omissions in Leidos' public filings with the SEC and other public statements during the period from May 4, 2020 to February 23, 2021 relating, among other things, to Leidos' acquisition of the SD&A Businesses. The plaintiff sought to recover from the Company and the individual defendants an unspecified amount of damages at this time. On July 30, 2021, the District Court appointed a lead plaintiff and lead counsel. On September 28, 2021, the lead plaintiff voluntarily dismissed the action without prejudice.

Other 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.

As of October 1, 2021, indirect cost active audits by the Defense Contract Audit Agency remain open for fiscal 2016 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 October 1, 2021, we believe we have adequately reserved for potential adjustments from audits or reviews of contract costs.

Commitments

We have outstanding letters of credit of $68 million as of October 1, 2021, principally related to performance guarantees on contracts. We also have outstanding surety bonds with a notional amount of $132 million, 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.

As of October 1, 2021, the future expirations of the outstanding letters of credit and surety bonds were as follows:

Accounting Policies [Abstract]

Consolidation

We have a controlling interest in Mission Support Alliance, LLC ("MSA"), a joint venture with Centerra Group, LLC. We also have a 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. The financial results for MSA and HMIS are consolidated into our unaudited condensed consolidated financial statements. The unaudited condensed 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 unaudited condensed consolidated financial statements for the periods presented. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation.

Basis of Accounting

The accompanying unaudited condensed financial information has been prepared in accordance with the rules of the U.S. Securities and Exchange Commission and accounting principles generally accepted in the United States of America ("GAAP"). Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules.

Estimates

The preparation of financial statements in conformity with 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 assets and lease liabilities, fair value and impairment of intangible assets and goodwill, income taxes, 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.

Accounting Standards Updates Adopted and Updates Issued But Not Yet Adopted

ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity's Own Equity (Subtopic 815-40)

In August 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-06 which simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separate embedded conversion features from the host convertible instruments. Additionally, the amendments in this update simplify the guidance in Subtopic 815-40 by removing certain criteria that must be satisfied in order to classify a contract as equity. This update also improves the consistency of earnings per share calculations by requiring an entity to use the if-converted method of calculating diluted earnings per share rather than the treasury stock method for convertible instruments and also by requiring the inclusion of the potential effect of shares settled in cash or shares in the diluted earnings per share calculation. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2021, and adopted using either a fully or modified retrospective approach. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. Entities should adopt the guidance as of the beginning of the fiscal year of adoption and cannot adopt the guidance in an interim reporting period.

Effective January 2, 2021, we adopted the requirements of ASU 2020-06 using the modified retrospective method. The adoption did not have an impact to our financial position, results of operations and earnings per share.

ASU 2021-05, Leases (Topic 842) Lessors—Certain Leases with Variable Lease Payments

In July 2021, the FASB issued ASU 2021-05, which amends lessor’s accounting for leases with variable lease payments classified as sales-type or direct financing leases. The amendments in this update modify the lease classification requirements for lessors, whereby leases with variable lease payments that are not dependent on a reference index or a rate will be accounted for as operating leases if classification as a sales-type or direct financing lease would have resulted in a day-one loss. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2021, as well as interim periods within those fiscal years, and can be adopted using either a prospective or retrospective approach. Early adoption is also permitted.

Effective July 3, 2021, we adopted the requirements of ASU 2021-05 using the prospective method. The adoption did not have an impact to our financial position, results of operations and earnings per share.

Accounting Standards Updates Issued But Not Yet Adopted

ASU 2020-04 and ASU 2021-01, Reference Rate Reform (Topic 848)

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. 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 reference rate reform. We currently use the one-month LIBOR for which the rate publication will cease in June 2023.

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

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.

Restricted Cash

We have restricted cash balances, primarily representing advances from customers that are restricted for use on certain expenditures related to that customer's contract. Restricted cash balances are included as "Other current assets" in the condensed consolidated balance sheets.
