NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. DESCRIPTION OF BUSINESS

Huntington Ingalls Industries, Inc. ("HII" or the "Company") is one of America’s largest military shipbuilding companies and a provider of professional services to partners in government and industry. HII is organized into three reportable segments: Ingalls Shipbuilding ("Ingalls"), Newport News Shipbuilding ("Newport News"), and Technical Solutions. For more than a century, the Company's Ingalls segment in Mississippi and Newport News segment in Virginia have built more ships in more ship classes than any other U.S. naval shipbuilder. The Technical Solutions segment provides a range of services to government and commercial customers.

HII conducts most of its business with the U.S. Government, primarily the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member, or partner, the Company participates in many high-priority U.S. defense programs. Through its Ingalls segment, HII is a builder of amphibious assault and expeditionary warfare ships for the U.S. Navy, the sole builder of National Security Cutters for the U.S. Coast Guard, and one of only two companies that builds the Navy's current fleet of Arleigh Burke class (DDG 51) destroyers. Through its Newport News segment, HII is the nation's sole designer, builder, and refueler of nuclear-powered aircraft carriers, and one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy. The Technical Solutions segment provides a wide range of professional services and products, including defense and federal solutions ("DFS"), nuclear and environmental services, and unmanned systems.

2. BASIS OF PRESENTATION

Principles of Consolidation - The unaudited condensed consolidated financial statements of HII and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-Q promulgated by the Securities and Exchange Commission ("SEC"). All intercompany transactions and balances are eliminated in consolidation. For classification of current assets and liabilities related to its long-term production contracts, the Company uses the duration of these contracts as its operating cycle, which is generally longer than one year.

These unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature considered necessary by management for a fair presentation of the unaudited condensed consolidated financial position, results of operations, and cash flows and should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020.

The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30, and third quarter as ending on September 30. It is management's long-standing practice to establish interim closing dates using a "fiscal" calendar, which requires the businesses to close their books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. The effects of this practice only exist for interim periods within a reporting year.

Accounting Estimates - The preparation of the Company's unaudited condensed consolidated financial statements requires management to make estimates and judgments 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 period. Estimates have been prepared on the basis of the most current and best available information, and actual results could differ materially from those estimates.

Additionally, the Company has incorporated realized and estimated future effects of the global outbreak of coronavirus disease 2019 (“COVID-19”), including, among other things, orders of civil authorities associated with COVID-19 and steps taken to mitigate the effects of COVID-19 (collectively, “COVID-19 Events”), with respect to contract costs and revenue recognition, effective income tax rates, and the fair values of the Company’s long-lived assets, financial instruments, intangible assets, and goodwill recorded at our reporting units. While costs related to COVID-19 Events are allowable under U.S. Government contracts, the Company's estimates of the effects of COVID-19 Events reflect uncertainty regarding the Company's ability to recover the full costs related to COVID-19 Events under government relief actions such as the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") and U.S. Department of Defense ("DoD") guidance.

Table of Contents

Government Grants - The Company recognizes incentive grants, inclusive of transfers of depreciable assets, from federal, state, and local governments at fair value upon compliance with the conditions of their receipt and reasonable assurance that the grants will be received or the depreciable assets will be transferred. Grants in recognition of specific expenses are recognized in the same period as an offset to those related expenses. Grants related to depreciable assets are recognized over the periods and in the proportions in which depreciation expense on those assets is recognized.

For the three months ended March 31, 2021, the Company recognized cash grant benefits of approximately $1 million in other long-term liabilities in the unaudited condensed consolidated statements of financial position. For the three months ended March 31, 2020, the Company recognized cash grant benefits of approximately $5 million in other long-term liabilities in the unaudited condensed consolidated statements of financial position.

Fair Value of Financial Instruments - Except for the Company's long-term debt, the carrying amounts of the Company's financial instruments recorded at historical cost approximate fair value due to the short-term nature of the instruments and low credit risk associated with the respective counterparties.

The Company maintains multiple grantor trusts to fund certain non-qualified pension plans. These trusts were valued at $191 million and $182 million as of March 31, 2021, and December 31, 2020, respectively, and are presented within miscellaneous other assets within the unaudited condensed consolidated statements of financial position. These trusts consist primarily of investments in marketable securities, which are held at fair value within Level 1 of the fair value hierarchy.

Loan Receivable - The Company holds a loan receivable in connection with a seller financed transaction involving its previously owned Avondale Shipyard facility. The receivable is carried at amortized cost of $34 million, net of $15 million of loan discount as of each of March 31, 2021, and December 31, 2020, which approximates fair value and is recorded in miscellaneous other assets on the unaudited condensed consolidated statements of financial position. Interest income is recognized on an accrual basis using the effective yield method. The discount is accreted into income using the effective yield method over the estimated life of the loan receivable.

Other Current Liabilities - Other current liabilities were $531 million as of March 31, 2021, and $462 million as of December 31, 2020. Payroll taxes payable, which is a component of other current liabilities, was $127 million as of March 31, 2021, and $125 million as of December 31, 2020. No other component of other current liabilities was more than 5% of total current liabilities.

Related Party Transactions - The Company had $84 million outstanding under Industrial Revenue Bonds issued by the Mississippi Business Finance Corporation as of each of March 31, 2021, and December 31, 2020. Prior to the Company's spinoff from Northrop Grumman Corporation, repayment of principal and interest was guaranteed by Northrop Grumman Systems Corporation. The guaranty remains in effect, and the Company has agreed to indemnify Northrop Grumman Systems Corporation for any losses related to the guaranty pursuant to the Separation and Distribution Agreement with Northrop Grumman Corporation.

3. ACCOUNTING STANDARDS UPDATES

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which amends and simplifies the requirements for income taxes. The ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, with early adoption permitted. The adoption did not result in a material impact to the Company's financial results or disclosures.

Accounting pronouncements issued but not effective until after December 31, 2021, are not expected to have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

4. ACQUISITIONS AND DIVESTITURES

Acquisitions

In December 2020, the Company acquired the autonomy business of Spatial Integrated Systems, Inc. ("SIS"), a leading provider of autonomous technology, for approximately $40 million in cash. The acquisition further expanded the Company's unmanned systems capabilities. In connection with this acquisition, the Company preliminarily

Table of Contents

recorded $40 million of goodwill, which included the value of SIS's workforce, all of which was allocated to the Company's Technical Solutions segment. For the three months ended March 31, 2021, the Company recorded a decrease in goodwill of $13 million, due to a reallocation to intangible assets related to technology and existing contract backlog. The Company has not completed the purchase price allocation, because the fair value calculations for certain assets and liabilities have not been finalized. See Note 10: Goodwill and Other Intangible Assets. The assets, liabilities, and results of operations of SIS are not material to the Company’s consolidated financial position, results of operations, or cash flows.

In March 2020, the Company acquired Hydroid, Inc. ("Hydroid"), a leading provider of advanced marine robotics to the defense and maritime markets, for approximately $377 million in cash, net of $2 million of acquired cash. The acquisition expanded the Company's capabilities in the strategically important and rapidly growing autonomous and unmanned maritime systems market. In connection with this acquisition, the Company recorded $239 million of goodwill, which included the value of Hydroid's workforce, and $76 million of intangible assets related to technology and existing contract backlog. See Note 10: Goodwill and Other Intangible Assets. The assets, liabilities, and results of operations of Hydroid are not material to the Company’s consolidated financial position, results of operations, or cash flows.

The Company funded each of these acquisitions using cash on hand, issuances of commercial paper, or borrowings on its revolving credit facility. The acquisition costs incurred in connection with these acquisitions were not material. The operating results of these businesses have been included in the Company’s consolidated results as of the respective closing dates of the acquisitions. In allocating the purchase prices of these businesses, the Company considered the estimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill. The total amount of goodwill resulting from these acquisitions is expected to be amortizable for tax purposes. These acquisitions are not material either individually or in the aggregate, and pro forma revenues and results of operations have therefore not been provided.

Divestitures

On February 1, 2021, the Company divested its San Diego Shipyard (“SDSY”) business in exchange for a non-controlling interest in Titan Acquisition Holdings, L.P. ("Titan"). Titan is a leading provider of ship repair and specialty fabrication services to government and commercial customers. The divestiture was completed as part of the Company’s operating strategy. The Company recognized its interest in Titan at fair value, which approximates $83 million. No gain or loss was recognized in the transaction. The assets and liabilities divested were previously reported in assets and liabilities held for sale. For the three months ended March 31, 2021, the Company transferred $12 million to Titan as part of the exchange.

On February 1, 2021, the Company completed the sale of its oil and gas business. The divestiture was completed as part of the Company’s plan to exit this part of the oil and gas industry and focus on its core services and customers. In connection with the sale, the Company received $25 million net cash and recorded a net pre-tax gain of $3 million in other income and gains within operating income in the unaudited condensed consolidated statements of operations. The assets and liabilities divested were previously reported in assets and liabilities held for sale.

5. STOCKHOLDERS' EQUITY

Treasury Stock - In November 2019, the Company's board of directors authorized an increase in the Company's stock repurchase program from $2.2 billion to $3.2 billion and an extension of the term of the program to October 31, 2024. Repurchases are made from time to time at management's discretion in accordance with applicable federal securities laws. For the three months ended March 31, 2021, the Company repurchased 291,581 shares at an aggregate cost of $50 million, of which approximately $1 million was not yet settled for cash as of March 31, 2021. For the three months ended March 31, 2020, the Company repurchased 390,904 shares at an aggregate cost of $84 million. The cost of purchased shares is recorded as treasury stock in the unaudited condensed consolidated statements of financial position.

Dividends - The Company declared cash dividends per share of $1.14 and $1.03 for the three months ended March 31, 2021 and 2020, respectively. The Company paid cash dividends totaling $46 million and $42 million for the three months ended March 31, 2021 and 2020, respectively.

Table of Contents

Accumulated Other Comprehensive Loss - Other comprehensive income (loss) refers to gains and losses recorded as an element of stockholders' equity but excluded from net earnings.

7. REVENUE

The following is a description of principal activities from which the Company generates its revenues. For more detailed information regarding reportable segments, see Note 8: Segment Information.

U.S. Government Contracts

The Ingalls and Newport News segments generate revenue primarily from performance under multi-year contracts with the U.S. Government, generally the U.S. Navy and U.S. Coast Guard, or prime contractors to contracts with the U.S. Government, relating to the advance planning, design, construction, repair, maintenance, refueling, overhaul, or inactivation of nuclear-powered ships and non-nuclear ships. The period over which the Company performs may extend past five years. The Technical Solutions segment also generates the majority of its revenue from contracts with the U.S. Government, including U.S. Government agencies. The Company generally invoices and receives related payments based upon performance progress no less frequently than monthly.

Shipbuilding - For most of the Company's shipbuilding contracts, the customer contracts with the Company to provide a comprehensive service of designing, procuring long-lead-time materials, manufacturing, and integrating complex equipment and technologies into a single ship or project, often resulting in a single performance obligation. Contract modifications to account for changes in specifications and requirements are recognized when approved by the customer. In the majority of circumstances, modifications do not result in additional performance obligations that are distinct from the existing performance obligations in the contract and the effects of the modifications are recognized as an adjustment to revenue on a cumulative catch-up basis. Alternatively, in instances where the performance obligations in the modifications are deemed distinct, contract modifications are accounted for prospectively.

The Company considers incentive and award fees to be variable consideration and includes in the transaction price at inception the consideration to which the Company expects to be entitled under the terms and conditions of the contract, generally estimated using a most likely amount approach. Transaction price is limited to the extent of funding allotted by the customer and available for performance, and estimated revenues represent those amounts for which the Company believes a significant reversal of revenue is not probable.

The Company recognizes revenues related to shipbuilding contracts as it satisfies the related performance obligations over time using a cost-to-cost input method to measure performance progress, which best reflects the transfer of control to the customer.

Services - The Technical Solutions segment generates revenue primarily under U.S. Government contracts from the provision of DFS services. Contracts generally are structured using either an Indefinite Delivery/Indefinite Quantity ("IDIQ") vehicle, under which orders are issued, or a standalone contract. Contracts may be fixed-price or cost-type, include variable consideration such as incentives and awards, and structured as task orders under an IDIQ contract vehicle or requirements contract vehicle. In either case, the Company generally performs services over a shorter duration and may continue to perform upon exercise of related period of performance options that are also shorter in duration. The Company’s performance obligations vary in nature and may be stand-ready, in which case the Company responds to the customer’s needs on the basis of its demand, a recurring service, typically recurring maintenance services, or a single performance obligation that does not comprise a series of distinct services.

In determining transaction price, the Company considers incentives and other contingencies to be variable consideration and includes in the initial transaction price the consideration to which the Company expects to be entitled under the terms and conditions of the contract, generally estimated using a most likely amount approach. Transaction price is limited to the extent of funding allotted by the customer and available for performance, and estimated revenues represent those amounts for which the Company believes a significant reversal of revenue is not probable. Where a series of distinct services has been identified, the Company generally allocates variable consideration to distinct time increments of service.

The Company generally recognizes revenue as it satisfies the related performance obligations over time using a cost-to-cost input method to measure performance progress, because, even where the Company has identified a series of services, its cost incurrence pattern generally is not ratable given the complex nature of the services the Company provides. Invoices are issued and related payments are received, on the basis of performance progress, no less frequently than monthly. In addition, many of the Company's U.S. Government services contracts are time and material arrangements. As a result, the Company often utilizes the practical expedient allowing the recognition

of revenue in the amount the Company invoices, which corresponds with the value provided to the customer and to which the Company is entitled to payment for performance to date.

Non-U.S. Government Contracts

Revenues generated under commercial and state and local government agency contracts are primarily derived from the provision of nuclear and environmental services. Non-U.S. Government contracts typically are one or two years in duration.

In determining transaction price, the Company considers incentives and other contingencies to be variable consideration and includes in the initial transaction price the consideration to which the Company expects to be entitled under the terms and conditions of the contract, generally estimated using a most likely amount approach. In the context of variable consideration, the Company limits the transaction price to amounts for which the Company believes a significant reversal of revenue is not probable. Such amounts may relate to transaction price in excess of funding, a lack of history with the customer, a lack of history with the goods or services being provided, or other items.

Revenue generally is recognized over time given the terms and conditions of the related contracts. The Company generally utilizes a cost-to-cost input method to measure performance progress, which best depicts the transfer of control to the customer. The Company’s non-U.S. Government contract portfolio is comprised of a large number of time and material arrangements. As a result, the Company often utilizes the practical expedient allowing the recognition of revenue in the amount the Company invoices, which corresponds with the value provided to the customer and to which the Company is entitled to payment for performance to date.

Disaggregation of Revenue

The following tables present revenues on a disaggregated basis, in a manner that reconciles with the Company's reportable segment disclosures, for the following categories: product versus service type, customer type, contract type, and major program. The Company believes that this level of disaggregation provides investors with information to evaluate the Company’s financial performance and provides the Company with information to make capital allocation decisions in the most appropriate manner.

As of March 31, 2021, the Company had $48.8 billion of remaining performance obligations. The Company expects to recognize approximately 30% of its remaining performance obligations as revenue through 2022, an additional 30% through 2024, and the balance thereafter.

Cumulative Catch-up Adjustments

For the three months ended March 31, 2021, net cumulative catch-up adjustments increased operating income and increased diluted earnings per share by $50 million and $0.98, respectively. For the three months ended March 31, 2020, net cumulative catch-up adjustments increased operating income and increased diluted earnings per share by

Table of Contents

$32 million and $0.62, respectively.

Cumulative catch-up adjustments for the three months ended March 31, 2021, included a favorable adjustment of $25 million on a contract at the Company's Ingalls segment, which increased diluted earnings per share by $0.50. No individual adjustment was material to the Company's unaudited condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2020.

Contract Balances

Contract balances include accounts receivable, contract assets, and contract liabilities associated with customer contracts. Accounts receivable represent an unconditional right to consideration and include amounts billed and currently due from customers. Contract assets primarily relate to the Company's rights to consideration for work completed but not billed as of the reporting date when the right to payment is not just subject to the passage of time. Fixed-price contracts are generally billed to the customer using either progress payments, whereby amounts are billed monthly as costs are incurred or work is completed, or performance based payments, which are based upon the achievement of specific, measurable events or accomplishments defined and valued at contract inception. Cost-type contracts are typically billed to the customer on a monthly or semi-monthly basis. Contract liabilities relate to advance payments, billings in excess of revenues, and deferred revenue amounts.

The Company reports contract balances in a net contract asset or contract liability position on a contract-by-contract basis at the end of each reporting period. The Company’s net contract assets increased $124 million from December 31, 2020, to March 31, 2021, primarily resulting from an increase in contract assets due to revenue on certain U.S. Navy contracts. For the three months ended March 31, 2021, the Company recognized revenue of $397 million related to its contract liabilities as of December 31, 2020. For the three months ended March 31, 2020, the Company recognized revenue of $274 million related to its contract liabilities as of December 31, 2019.

10. GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

HII performs impairment tests for goodwill as of November 30 of each year and between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair values of the Company's reporting units below their carrying values.

Accumulated goodwill impairment losses as of each of March 31, 2021, and December 31, 2020, were $2,906 million. The accumulated goodwill impairment losses for Ingalls as of each of March 31, 2021, and December 31, 2020, were $1,568 million. The accumulated goodwill impairment losses for Newport News as of each of March 31, 2021, and December 31, 2020, were $1,187 million. The accumulated goodwill impairment losses for Technical Solutions as of each of March 31, 2021, and December 31, 2020, were $151 million.

For the three months ended March 31, 2021, the carrying amounts of goodwill changed as follows:


($ in millions)	Ingalls		Newport News		Technical Solutions		Total
Balance as of December 31, 2020	$	175	$	721	$	721	$	1,617

As of March 31, 2021, the Company recorded goodwill adjustments of $13 million relating to the acquisition of SIS, primarily related to allocations to intangible assets.

Table of Contents

Other Intangible Assets

The Company's purchased intangible assets are amortized on a straight-line basis or a method based on the pattern of benefits over their estimated useful lives. Net intangible assets consist primarily of amounts relating to nuclear-powered aircraft carrier and submarine program intangible assets, with an aggregate weighted-average useful life of 40 years based on the long life cycle of the related programs. Aggregate amortization expense was $13 million and $11 million for the three months ended March 31, 2021 and 2020, respectively.

In connection with the SIS purchase in 2020, the Company recorded $13 million of intangible assets pertaining to technology and existing contract backlog, which is being amortized using the pattern of benefits method over a weighted-average life of ten years.

In connection with the Hydroid purchase in 2020, the Company recorded $76 million of intangible assets pertaining to existing contract backlog, customer relationships, and technology, which is being amortized using the pattern of benefits method over a weighted-average life of nine years.

The Company expects amortization expense for purchased intangible assets of approximately $52 million in 2021, $46 million in 2022, $37 million in 2023, $28 million in 2024, and $28 million in 2025.

11. INCOME TAXES

The Company's earnings are primarily domestic, and its effective income tax rates on earnings from operations for the three months ended March 31, 2021 and 2020, were 14.5% and 20.4%, respectively. The lower effective tax rate for the three months ended March 31, 2021, was primarily attributable to the tax loss associated with the sale of the Company’s oil and gas business resulting in a reduction in the effective tax rate of 5.5%.

For the three months ended March 31, 2021, the Company’s effective tax rate differed from the federal statutory tax rate primarily as a result of the tax loss associated with the sale of its oil and gas business. For the three months ended March 31, 2020, the Company's effective tax rate did not differ materially from the federal statutory corporate income tax rate of 21%.

The Company's unrecognized tax benefits increased by $3 million during the three months ended March 31, 2021. As of March 31, 2021, the estimated amounts of the Company's unrecognized tax benefits, excluding interest and penalties, were liabilities of $50 million. Assuming a sustainment of these tax positions, the reversal of $36 million of the accrued amounts would favorably affect the Company's effective federal income tax rate in future periods.

The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. For the three months ended March 31, 2021, interest resulting from the unrecognized tax benefits noted above increased income tax expense less than $1 million.

Non-current state income taxes include deferred state income taxes, which reflect the change in deferred state tax assets and liabilities, and the tax expense or benefit associated with changes in unrecognized state tax benefits in the relevant period. These amounts are recorded within operating income. Current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

12. DEBT

Long-term debt consisted of the following:

Table of Contents

Credit Facility - The Company's credit facility (the "Credit Facility") includes a revolving credit facility of $1,250 million, which may be drawn upon during a period of five years from November 22, 2017. The revolving credit facility includes a letter of credit subfacility of $500 million.

The Credit Facility contains customary affirmative and negative covenants, as well as a financial covenant based on a maximum total leverage ratio. Each of the Company's existing and future material wholly owned domestic subsidiaries, except those that are specifically designated as unrestricted subsidiaries, are and will be guarantors under the Credit Facility. See Note 17: Subsidiary Guarantors.

As of March 31, 2021, the Company had $15 million in issued but undrawn letters of credit and $1,235 million unutilized under the Credit Facility. The Company had unamortized debt issuance costs associated with its credit facilities of $3 million and $5 million as of March 31, 2021, and December 31, 2020, respectively.

The terms of the Company’s senior notes limit the Company’s ability and the ability of certain of its subsidiaries to create liens, enter into sale and leaseback transactions, sell assets, and effect consolidations or mergers. The Company had unamortized debt issuance costs associated with its senior notes of $14 million as of each of March 31, 2021, and December 31, 2020.

Under the Company's unsecured commercial paper program, the Company may issue up to $1 billion of unsecured commercial paper notes.

The Company's debt arrangements contain customary affirmative and negative covenants. The Company was in compliance with all debt covenants during the three months ended March 31, 2021.

The estimated fair values of the Company's total long-term debt as of March 31, 2021, and December 31, 2020, were $1,874 million and $1,943 million, respectively. The fair values of the Company's long-term debt were calculated based on recent trades of the Company's debt instruments in inactive markets, which fall within Level 2 under the fair value hierarchy.

As of March 31, 2021, the aggregate amounts of principal payments due on long-term debt within the next five years consisted of $84 million due in 2024 and $500 million due in 2025.

13. INVESTIGATIONS, CLAIMS, AND LITIGATION

The Company is involved in legal proceedings before various courts and administrative agencies, and is periodically subject to government examinations, inquiries and investigations. Pursuant to FASB Accounting Standards Codification 450 Contingencies, the Company has accrued for losses associated with investigations, claims, and litigation when, and to the extent that, loss amounts related to the investigations, claims, and litigation are probable and can be reasonably estimated. The actual losses that might be incurred to resolve such investigations, claims, and litigation may be higher or lower than the amounts accrued. For matters where a material loss is probable or reasonably possible and the amount of loss cannot be reasonably estimated, but the Company is able to reasonably estimate a range of possible losses, the Company will disclose such estimated range in these notes. This estimated range is based on information currently available to the Company and involves elements of judgment and significant uncertainties. Any estimated range of possible loss does not represent the Company's maximum possible loss exposure. For matters as to which the Company is not able to reasonably estimate a possible loss or range of loss, the Company will indicate the reasons why it is unable to estimate the possible loss or range of loss. For matters not specifically described in these notes, the Company does not believe, based on information currently available to it, that it is reasonably possible that the liabilities, if any, arising from such investigations, claims, and litigation will have a material effect on its consolidated financial position, results of operations, or cash flows. The Company has, in certain cases, provided disclosure regarding certain matters for which the Company believes at this time that the likelihood of material loss is remote.

False Claims Act Complaint - In 2016, the Company was made aware that it is a defendant in a qui tam False Claims Act lawsuit pending in the U.S. District Court for the Middle District of Florida related to the Company’s purchases of allegedly non-conforming parts from a supplier for use in connection with U.S. Government contracts. In August 2019, the Department of Justice (“DoJ”) declined to intervene in the lawsuit, and the lawsuit was unsealed. The court dismissed the complaint, but the plaintiff was permitted to refile the compliant and did so. The case is at an early stage, and the Company has filed a motion to dismiss the Second Amended Complaint. As a

Table of Contents

result, the Company is unable to estimate an amount or range of reasonably possible loss or to express an opinion regarding the ultimate outcome of the matter.

Insurance Claims - In September 2020, the Company filed a complaint in the Superior Court, State of Vermont, Franklin Unit, seeking a judgment declaring that the Company's business interruption and other losses associated with COVID-19 are covered by the Company's property insurance program. A total of 32 reinsurers are named as defendants in the complaint. The Company also has initiated arbitration proceedings against six other reinsurers seeking similar relief. Prior to filing the complaint and initiating the arbitration proceedings, the Company provided a notice of loss to the reinsurers, but, to date, none of the reinsurers have acknowledged coverage. The full extent of the Company's losses resulting from COVID-19 have not yet been determined, and the process of calculating losses is continuing. Although the Company believes its position is well-founded, no assurances can be provided regarding the ultimate resolution of this matter.

U.S. Government Investigations and Claims - Departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of the Company, and the results of such investigations may lead to administrative, civil, or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory, treble, or other damages. U.S. Government regulations provide that certain findings against a contractor may also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Any suspension or debarment would have a material effect on the Company because of its reliance on government contracts.

Asbestos Related Claims - HII and its predecessors-in-interest are defendants in a longstanding series of cases that have been and continue to be filed in various jurisdictions around the country, wherein former and current employees and various third parties allege exposure to asbestos containing materials while on or associated with HII premises or while working on vessels constructed or repaired by HII. The cases allege various injuries, including those associated with pleural plaque disease, asbestosis, cancer, mesothelioma, and other alleged asbestos related conditions. In some cases, several of HII's former executive officers are also named as defendants. In some instances, partial or full insurance coverage is available to the Company for its liability and that of its former executive officers. The costs to resolve cases during the three months ended March 31, 2021 and 2020, were immaterial individually and in the aggregate. The Company’s estimate of asbestos-related liabilities is subject to uncertainty because liabilities are influenced by numerous variables that are inherently difficult to predict. Key variables include the number and type of new claims, the litigation process from jurisdiction to jurisdiction and from case to case, reforms made by state and federal courts, and the passage of state or federal tort reform legislation. Although the Company believes the ultimate resolution of current cases will not have a material effect on its consolidated financial position, results of operations, or cash flows, it cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of asbestos related litigation.

Other Litigation - In March 2019, a new dry dock being transported for delivery to Ingalls by a heavy lift ship struck an Ingalls work barge, which in turn was pushed into Delbert D. Black (DDG 119) causing damage to Delbert D. Black (DDG 119), the work barge, and the new dry dock. At the time of the incident, responsibility for the new dry dock remained with the builder and the transport company. Repair work on Delbert D. Black (DDG 119) was completed at U.S. Navy direction. The Company is working with the U.S. Navy to ascertain whether third parties will pay for the repairs to Delbert D. Black (DDG 119) or whether the repairs will be paid under the builder's risk insurance included in the Delbert D. Black (DDG 119) contract. Claims were tendered to the Company's insurers, and the Company has received all outstanding claim proceeds. In April 2019, the Company filed suit in the U.S. District Court for the Southern District of Mississippi seeking, among other relief, damages from negligent third parties. Based on information currently available, management believes it will collect sufficient funds from one or more third parties to compensate for the resulting direct and consequential damages, but failure to collect sufficient funds or the length of time required to collect such funds could result in a material effect on the Company’s financial position, results of operations, or cash flows.

The Company and its predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the "Republic") since 2002 over a contract for the repair, refurbishment, and modernization at Ingalls of two foreign-built frigates. In March 2014, the Company filed an arbitral statement of claim asserting breaches of the contract. The Republic denied the Company’s allegations and asserted counterclaims. In February 2018, the arbitral tribunal awarded the Company approximately $151 million on its claims and awarded the Republic approximately $22 million on its counterclaims. The Company is seeking to enforce and execute upon the award in multiple jurisdictions. No assurances can be provided regarding the ultimate resolution of this matter.

Table of Contents

The Company is party to various other claims, legal proceedings and investigations that arise in the ordinary course of business, including U.S. Government investigations that could result in administrative, civil, or criminal proceedings involving the Company. The Company is a contractor with the U.S. Government, and such proceedings can therefore include False Claims Act allegations against the Company. Although the Company believes that the resolution of these other claims, legal proceedings and investigations will not have a material effect on its consolidated financial position, results of operations, or cash flows, the Company cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of these matters.

14. COMMITMENTS AND CONTINGENCIES

Contract Performance Contingencies - Contract profit margins may include estimates of revenues for matters on which the customer and the Company have not reached agreement, such as settlements in the process of negotiation, contract changes, claims, and requests for equitable adjustment for unanticipated contract costs. These estimates are based upon management's best assessment of the underlying causal events and circumstances and recognized to the extent of expected recovery based upon contractual entitlements and the probability of successful negotiation with the customer. As of March 31, 2021, amounts recognized in connection with claims and requests for equitable adjustment were not material individually or in the aggregate.

Guarantees of Performance Obligations - From time to time in the ordinary course of business, HII enters into joint ventures, teaming agreements, and other business arrangements in connection with the Company's products and services or to pursue strategic objectives. The Company attempts to limit its exposure under these arrangements to its investment or the extent of obligations under the applicable contract. In some cases, however, HII may be required to guarantee performance of the arrangement's obligations and, in such cases, generally obtains cross-indemnification from the other members of the arrangement.

In the ordinary course of business, the Company may guarantee obligations of its subsidiaries under certain contracts. Generally, the Company is liable under such guarantees only if its subsidiary is unable to perform its obligations. Historically, the Company has not incurred any substantial liabilities resulting from these guarantees. As of March 31, 2021, the Company was not aware of any existing event of default that would require it to satisfy any of these guarantees.

Environmental Matters - The estimated cost to complete environmental remediation has been accrued when it is probable that the Company will incur such costs in the future to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where it has been named a Potentially Responsible Party ("PRP") by the Environmental Protection Agency or similarly designated by another environmental agency, and the related costs can be estimated by management. These accruals do not include any litigation costs related to environmental matters, nor do they include amounts recorded as asset retirement obligations. To assess the potential impact on the Company's consolidated financial statements, management estimates the range of reasonably possible remediation costs that could be incurred by the Company, taking into account currently available facts on each site, as well as the current state of technology and prior experience remediating contaminated sites. These estimates are reviewed periodically and adjusted to reflect changes in facts and technical and legal circumstances. Management estimates that as of March 31, 2021, the probable estimable future cost for environmental remediation was immaterial. Factors that could result in changes to the Company's estimates include: modification of planned remedial actions, increases or decreases in the estimated time required to remediate, changes to the determination of legally responsible parties, discovery of more extensive contamination than anticipated, changes in laws and regulations affecting remediation requirements, and improvements in remediation technology. Should other PRPs not pay their allocable share of remediation costs, the Company may incur costs exceeding those already estimated and accrued. In addition, there are certain potential remediation sites where the costs of remediation cannot be reasonably estimated. Although management cannot predict whether new information gained as remediation progresses will materially affect the estimated liability accrued, management does not believe that future remediation expenditures will have a material effect on the Company's consolidated financial position, results of operations, or cash flows.

Financial Arrangements - In the ordinary course of business, HII uses letters of credit issued by commercial banks to support certain leases, insurance policies, and contractual performance obligations, as well as surety bonds issued by insurance companies principally to support the Company's self-insured workers' compensation plans.

of March 31, 2021, the Company had $15 million in issued but undrawn letters of credit, as indicated in Note 12: Debt, and $272 million of surety bonds outstanding.

U.S. Government Claims - From time to time, the U.S. Government communicates to the Company potential claims, disallowed costs, and penalties concerning prior costs incurred by the Company with which the U.S. Government disagrees. When such preliminary findings are presented, the Company and U.S. Government representatives engage in discussions, from which the Company evaluates the merits of the claims and assesses the amounts being questioned. Although the Company believes that the resolution of any of these matters will not have a material effect on its consolidated financial position, results of operations, or cash flows, it cannot predict the ultimate outcome of these matters.

Other Matters - In 1985, the Company and the U.S. Navy entered into a settlement agreement to resolve disputes associated with billing and allocating to contracts the cost of workers’ compensation self-insurance, among other matters. In 2016, the Defense Contract Audit Agency ("DCAA") opined that the 1985 settlement agreement did not comply with certain CAS standards and referred the matter to a U.S. Navy’s Contracting Officer. In December 2020, the Contracting Officer issued a determination that the 1985 settlement agreement did not comply with CAS and directed the Company to develop and implement a different process to bill and allocate the cost of workers’ compensation self-insurance. Cumulatively, under the 1985 settlement agreement, the Company has not recognized as allowable billable costs of approximately $120 million due to the difference between CAS and U.S. GAAP Financial Accounting Standards ("FAS") treatment of workers’ compensation cost. Under the 1985 settlement agreement, these costs would be recognized as allowable billable costs in future periods. Though the Company believes the 1985 settlement agreement is CAS-compliant and cannot be unilaterally terminated, the Company will seek to negotiate a resolution of the matter with the Contracting Officer. If a resolution results in the use of a different treatment or billing methodology that does not provide for the Company to recognize as allowable the CAS to FAS difference, the resolution could have a material effect on the Company’s consolidated financial position, results of operations, or cash flows, including an inability to recover any or all of the $120 million of costs not yet billed to the customer.

Collective Bargaining Agreements - Of the Company's approximately 42,000 employees, approximately 50% are covered by a total of nine collective bargaining agreements and one site stabilization agreement. Newport News has three collective bargaining agreements covering represented employees, which expire in November 2021, December 2022, and April 2024. The collective bargaining agreement that expires in November 2021 covers approximately 50% of Newport News employees. Newport News craft workers employed at the Kesselring Site near Saratoga Springs, New York are represented under an indefinite Department of Energy ("DoE") site agreement. Ingalls has five collective bargaining agreements covering represented employees, all of which expire in March 2022. Approximately 25 Technical Solutions employees in Klamath Falls, Oregon are covered by a collective bargaining agreement that expires in June 2021. The Company believes its relationship with its employees is satisfactory.

Collective bargaining agreements generally expire after three to five years and are subject to renegotiation at that time. The Company does not expect the results of these negotiations, either individually or in the aggregate, to have a material effect on the Company's consolidated results of operations.

Purchase Obligations - Periodically the Company enters into agreements to purchase goods or services that are enforceable and legally binding on the Company and specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. These obligations are primarily comprised of open purchase order commitments to vendors and subcontractors pertaining to funded contracts.

15. EMPLOYEE PENSION AND OTHER POSTRETIREMENT BENEFITS

The Company provides eligible employees defined benefit pension plans, other postretirement benefit plans, and defined contribution pension plans.

16. STOCK COMPENSATION PLANS

During the three months ended March 31, 2021 and 2020, the Company issued new stock awards as follows:

Restricted Performance Stock Rights - For the three months ended March 31, 2021, the Company granted approximately 0.2 million RPSRs at a weighted average share price of $178.41. These rights are subject to cliff vesting on December 31, 2023. For the three months ended March 31, 2020, the Company granted approximately 0.1 million RPSRs at a weighted average share price of $229.42. These rights are subject to cliff vesting on December 31, 2022. All of the RPSRs are subject to the achievement of performance-based targets at the end of the respective vesting periods and will ultimately vest between 0% and 200% of grant date value.

For each of the three months ended March 31, 2021 and 2020, approximately 0.1 million of stock awards vested, of which less than 0.1 million each year were transferred to the Company from employees in satisfaction of minimum tax withholding obligations.

The following table summarizes the status of the Company's outstanding stock awards as of March 31, 2021:


	Stock Awards (in thousands)	Weighted-Average Grant Date Fair Value		Weighted-Average Remaining Contractual Term (in years)

Compensation Expense

The Company recorded stock-based compensation for the value of awards granted to Company employees and non-employee members of the board of directors for the three months ended March 31, 2021 and 2020, of $9 million and $7 million, respectively.

The Company recorded tax benefits related to stock awards of $2 million and $1 million for the three months ended March 31, 2021 and 2020, respectively. The Company recognized tax benefits associated with the issuance of stock in settlement of stock awards of $2 million for each of the three months ended March 31, 2021 and 2020.

Unrecognized Compensation Expense

As of March 31, 2021, the Company had less than $1 million of unrecognized compensation expense associated with Restricted Stock Rights granted in 2021, 2020, 2019 and 2018, which will be recognized over a weighted average period of 1.1 years, and $50 million of unrecognized compensation expense associated with RPSRs granted in 2021, 2020, and 2019, which will be recognized over a weighted average period of 1.8 years.

17. SUBSIDIARY GUARANTORS

As described in Note 12: Debt, the Company issued senior notes through the consolidating parent company, HII. Performance of the Company's obligations under its senior notes outstanding as of March 31, 2021, and December 31, 2020, including any repurchase obligations resulting from a change of control, is fully and unconditionally guaranteed, jointly and severally, on an unsecured basis, by each of HII's existing and future material domestic subsidiaries ("Subsidiary Guarantors"). The Subsidiary Guarantors are 100% owned by HII. Under SEC Regulation S-X Rule 3-10, each HII subsidiary that did not provide a guarantee ("Non-Guarantors") is minor and HII, as the parent company issuer, did not have independent assets or operations. There are no significant restrictions on the ability of the parent company and the Subsidiary Guarantors to obtain funds from their respective subsidiaries by dividend or loan, except those imposed by applicable law.

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

OVERVIEW

Our Business

Huntington Ingalls Industries, Inc. ("HII", "we", "us", or "our") is America’s largest military shipbuilding company and a provider of professional services to partners in government and industry. For more than a century, our Ingalls segment in Mississippi and Newport News segment in Virginia have built more ships in more ship classes than any other U.S. naval shipbuilder. Our Technical Solutions segment provides a range of services to government and commercial customers. Headquartered in Newport News, Virginia, HII employs approximately 42,000 people both domestically and internationally.

We conduct most of our business with the U.S. Government, primarily the DoD. As prime contractor, principal subcontractor, team member, or partner, we participate in many high-priority U.S. defense programs. Ingalls includes our non-nuclear ship design, construction, repair, and maintenance businesses. Newport News includes all of our nuclear ship design, construction, overhaul, refueling, and repair and maintenance businesses. Our Technical Solutions segment provides a wide range of professional services and products, including defense and federal solutions ("DFS"), nuclear and environmental services, and unmanned systems.

The following discussion should be read along with the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, as well as our Annual Report on Form 10-K for the year ended December 31, 2020.

Business Environment

COVID-19 Pandemic - The COVID-19 global pandemic has had wide ranging effects on the global health environment and disrupted the global and U.S. economies and financial markets, including impacts to our employees, customers, suppliers, and communities (collectively, “COVID-19 Events”). COVID-19 Events have also

Table of Contents

impacted our operations, and the continuing impacts are uncertain. The most significant elements of uncertainty have been the intensity and duration of the impact on our employees’ ability to work effectively, disruption in our supply chain, disruption of the U.S. Government's and our other customers' abilities to perform their obligations, and impact on pension assets and other investment performance.

We are aggressively managing our response to the uncertainties regarding COVID-19 Events. Our primary focus has been to minimize the risk to our employees by updating leave policies, increasing telecommuting, and making benefits changes to provide employees maximum flexibility. We have also adjusted policies and workspaces to align with Centers for Disease Control and Prevention (“CDC”) guidelines and to support social distancing, including increased sanitation efforts, personal protective equipment for employees, and suspension of all non-essential work travel. As a result, we have incurred and expect to continue incurring costs related to COVID-19 Events, including paid leave, quarantining employees, and recurring facility cleaning. Our shipyards and other facilities remained open and productive, but we experienced temporary decreases in workforce attendance, which impacted our operations due to delay and disruption from the lack of availability of critical skills and out-of-sequence work. As of March 31, 2021, our workforce was operating at normal attendance rates.

Under Section 3610 of the CARES Act, contractors may submit claims for employee paid time off caused by restrictions from COVID-19 Events in circumstances where the employee could not work remotely. Such instances may include paid time off for employees to allow for plant decontamination, idle time due to social distancing restrictions, paid time off to take care of dependents impacted by government ordered school or day care closures, and employee quarantines due to travel restrictions or coming into contact, being diagnosed, or taking care of someone diagnosed with COVID-19. We have taken steps to preserve our rights to pursue such claims for HII and our subcontractors, but we have no assurance that Congress will appropriate sufficient funds to cover the reimbursement of costs contemplated by the CARES Act.

While costs related to COVID-19 Events are allowable under U.S. Government contracts, our contract estimates reflect margin impact uncertainty, because such costs may not result in equitable adjustments, particularly on firm fixed price and fixed price incentive contracts, or may not be adequately covered by insurance. Our reinsurers have failed to acknowledge coverage for various losses related to COVID-19, and we filed a complaint in state court in Vermont seeking a judgment declaring that our business interruption and other losses associated with COVID-19 are covered by our property insurance program. We also initiated arbitration proceedings against other reinsurers seeking similar relief. Although we believe that our position is well-founded, no assurance can be provided regarding the ultimate resolution of this matter. See Note 13: Investigations, Claims, and Litigation.

We have also focused on actively supporting our customers, suppliers, and communities. We have been proactive in engaging with our U.S. Government customers regarding future contract adjustments. While there has been no change in contract terms or substantial degradation in timely payments from customers, we have experienced delays in decisions on certain contract awards. We are unable to predict how our customers will allocate resources in the future as they react to the evolving demands of the COVID-19 response. We have accelerated payments to small business suppliers in an effort to minimize supply chain disruption.

We temporarily halted stock repurchases in Q1 2020, but we resumed share repurchases during the first quarter of 2021. We also deferred certain payroll taxes pursuant to the CARES Act, which increased our cash from operations in 2020, but will reduce cash from operations in 2021 and 2022.

U.S. Government Contracts - Long-term uncertainty exists with respect to overall levels of defense spending across the future years' defense plan, and it is likely that U.S. Government discretionary spending levels will continue to be subject to significant pressure.

The fiscal year 2021 budget cycle ultimately concluded with the passage and enactment of defense authorization and defense appropriations measures. Both pieces of legislation broadly supported shipbuilding programs, including funding and authority for an additional Virginia class submarine, the bundled purchase of LHA 9 (unnamed) with LPD 32 (unnamed) and LPD 33 (unnamed), and long-lead material for an additional Arleigh Burke class (DDG 51) destroyer. The final bills also continued support of the dual purchase of Enterprise (CVN 80) and Doris Miller (CVN 81), as well as the Refueling and Complex Overhaul of USS John C. Stennis (CVN 74).

Long-term funding for certain programs in which we participate may be reduced, delayed, or canceled. In addition, spending cuts and/or reprioritization of defense investment could adversely affect the viability of our suppliers, subcontractors, and employee base. Our contracts or subcontracts under programs in which we participate may be

Table of Contents

terminated or adjusted by the U.S. Government or the prime contractor as a result of lack of government funding or reductions or delays in government funding. Significant reductions in the number of ships procured by the U.S. Navy or significant delays in funding our ship programs would have a material effect on our financial position, results of operations, or cash flows.

The budget environment remains a significant long-term risk. Considerable uncertainty exists regarding how future budget and program decisions will develop and what challenges budget changes will present for the defense industry. We believe continued budget pressures will have serious implications for defense discretionary spending, the defense industrial base, including HII, and the customers, employees, suppliers, subcontractors, investors, and communities that rely on companies in the defense industrial base. Although it is difficult to determine specific impacts, we expect that over the longer term, the budget environment may result in fewer contract awards and lower revenues, profits, and cash flows from our U.S. Government contracts. It is likely budget and program decisions made in this environment will have long-term impacts on HII and the entire defense industry.

Critical Accounting Policies, Estimates, and Judgments

As discussed in our Annual Report on Form 10-K for the year ended December 31, 2020, we consider our policies relating to the following matters to be critical accounting policies:

•Revenue recognition;

•Purchase accounting, goodwill, and intangible assets;

•Litigation, commitments, and contingencies;

•Retirement related benefit plans; and

•Workers' compensation.

As of March 31, 2021, there had been no material changes to the foregoing critical accounting policies, estimates, and judgments since December 31, 2020.

We have incorporated realized and estimated future effects of COVID-19 Events, based upon current conditions and our judgment of the future impacts of COVID-19 Events, with respect to contract costs and revenue recognition, effective income tax rates, and the fair values of our long-lived assets, financial instruments, intangible assets, and goodwill recorded at our reporting units. See Note 2: Basis of Presentation.

Contracts

We generate most of our revenues from long-term U.S. Government contracts for design, production, and support activities. Government contracts typically include the following cost elements: direct material, labor, and subcontracting costs, and certain indirect costs, including allowable general and administrative expenses. Unless otherwise specified in a contract, costs billed to contracts with the U.S. Government are treated as allowable and allocable costs under the Federal Acquisition Regulation ("FAR") and the U.S. Cost Accounting Standards ("CAS") regulations. Examples of costs incurred by us that are not allowable under the FAR and CAS regulations include certain legal costs, lobbying costs, charitable donations, interest expense, and advertising costs.

We monitor our policies and procedures with respect to our contracts on a regular basis to ensure consistent application under similar terms and conditions, as well as compliance with all applicable government regulations. In addition, the Defense Contract Audit Agency routinely audits the costs we incur that are allocated to contracts with the U.S. Government.

Our contracts typically fall into one of four categories: firm fixed-price, fixed-price incentive, cost-type, and time and materials. See Note 7: Revenue.

•Firm Fixed-Price Contracts - A firm fixed-price contract is a contract in which the specified scope of work is agreed to for a price that is predetermined by bid or negotiation and not generally subject to adjustment regardless of costs incurred by the contractor.

Table of Contents

•Fixed-Price Incentive Contracts - Fixed-price incentive contracts provide for reimbursement of the contractor's allowable costs, but are subject to a cost-share limit that affects profitability. Fixed-price incentive contracts effectively become firm fixed-price contracts once the cost-share limit is reached.

•Cost-Type Contracts - Cost-type contracts provide for reimbursement of the contractor's allowable costs plus a fee that represents profit. Cost-type contracts generally require that the contractor use its reasonable efforts to accomplish the scope of the work within some specified time and some stated dollar limitation.

•Time and Materials - Time and materials contracts specify a fixed hourly billing rate for each direct labor hour expended and reimbursement for allowable material costs and expenses.

Contract Fees - Negotiated contract fee structures include: fixed fee amounts, cost sharing arrangements to reward or penalize contractors for under or over cost target performance, respectively, positive award fees, and negative penalty arrangements. Profit margins may vary materially depending on the negotiated contract fee arrangements, percentage-of-completion of the contract, the achievement of performance objectives, and the stage of performance at which the right to receive fees, particularly under incentive and award fee contracts, is finally determined.

Award Fees - Certain contracts contain award fees based on performance criteria such as cost, schedule, quality, and technical performance. Award fees are determined and earned based on an evaluation by the customer of our performance against such negotiated criteria. We consider award fees to be variable consideration and generally include these fees in the transaction price using a most likely amount approach. Award fees are limited to the extent of funding allotted by the customer and available for performance and those amounts for which a significant reversal of revenue is not probable.

Program Descriptions

For convenience, a brief description of certain programs discussed in this Quarterly Report on Form 10-Q is included in the "Glossary of Programs" in this section.

Operating Performance Assessment and Reporting

We manage and assess the performance of our business based on our performance on individual contracts and programs using the financial measures referred to below, with consideration given to the Critical Accounting Policies, Estimates, and Judgments referred to in this section. Our portfolio of long-term contracts is largely flexibly-priced. Therefore, sales tend to fluctuate in concert with costs across our large portfolio of active contracts, with operating income being a critical measure of operating performance. Under FAR rules that govern our business with

Table of Contents

the U.S. Government, most types of costs are allowable, and we do not focus on individual cost groupings, such as cost of sales or general and administrative expenses, as much as we do on total contract costs, which are a key factor in determining contract operating income. As a result, in evaluating our operating performance, we look primarily at changes in sales and service revenues, as well as operating income, including the effects of significant changes in operating income as a result of changes in contract estimates and the use of the cumulative catch-up method of accounting in accordance with GAAP. This approach is consistent with the long-term life cycle of our contracts, as management assesses the bidding of each contract by focusing on net sales and operating profit and monitors performance in a similar manner through contract completion. Consequently, our discussion of business segment performance focuses on net sales and operating profit, consistent with our approach for managing our business.

Cost of sales for both product sales and service revenues consists of materials, labor, and subcontracting costs, as well as an allocation of indirect costs for overhead. We manage the type and amount of costs at the contract level, which is the basis for estimating our total costs at completion of our contracts. Unusual fluctuations in operating performance driven by changes in a specific cost element across multiple contracts are described in our analysis.

Sales and Service Revenues

Sales and service revenues were comprised as follows:


	Three Months Ended March 31
					2021 over 2020
($ in millions)	2021		2020		Dollars		Percent
Product sales	$	1,721	$	1,624	$	97	6	%
Service revenues	557		639		(82)		(13)	%
Sales and service revenues	$	2,278	$	2,263	$	15	1	%

Product sales for the three months ended March 31, 2021, increased $97 million, or 6%, compared with the same period in 2020. Ingalls product sales increased $26 million for the three months ended March 31, 2021, primarily as a result of higher volumes in surface combatants and amphibious assault ships, partially offset by lower volume in the Legend class NSC program. Newport News product sales increased $55 million for the three months ended March 31, 2021, primarily as a result of higher volumes in aircraft carriers. Technical Solutions product sales increased $16 million for the three months ended March 31, 2021, primarily as a result of the acquisition of Hydroid in March 2020 and higher volumes in DFS.

Service revenues for the three months ended March 31, 2021, decreased $82 million, or 13%, compared with the same period in 2020. Ingalls service revenues decreased $8 million for the three months ended March 31, 2021, primarily as a result of lower volumes in surface combatant and amphibious assault ship services. Newport News service revenues increased $11 million for the three months ended March 31, 2021, primarily as a result of higher volumes in aircraft carriers. Technical Solutions service revenues decreased $85 million for the three months ended March 31, 2021, primarily as a result of the divestitures of our oil and gas business and San Diego Shipyard, as well as lower volumes in DFS services.

Cost of Sales and Service Revenues

Cost of product sales, cost of service revenues, income from operating investments, net, and general and administrative expenses were as follows:

Cost of Product Sales

Cost of product sales for the three months ended March 31, 2021, increased $164 million, or 13%, compared with the same period in 2020. Ingalls cost of product sales increased $1 million for the three months ended March 31, 2021, primarily as a result of the higher volumes described above, partially offset by risk retirement on Bougainville (LHA 8). Newport News cost of product sales increased $64 million for the three months ended March 31, 2021, primarily as a result of volume increases described above. Technical Solutions cost of product sales increased $15 million for the three months ended March 31, 2021, primarily as a result of the volume increases described above. Cost of product sales related to the Operating FAS/CAS Adjustment increased $84 million for the three months ended March 31, 2021, as described below.

Cost of product sales as a percentage of product sales increased from 79.4% for the three months ended March 31, 2020, to 84.5% for the three months ended March 31, 2021. The increase was due to unfavorable change in the Operating FAS/CAS Adjustment and lower risk retirement on the RCOH of USS George Washington (CVN 73), partially offset by higher risk retirement on Bougainville (LHA 8) and Block IV of the Virginia class (SSN 774) submarine program and year-to-year variances in contract mix.

Cost of Service Revenues

Cost of service revenues for the three months ended March 31, 2021, decreased $68 million, or 12%, compared with the same period in 2020. Ingalls cost of service revenues decreased $7 million for the three months ended March 31, 2021, primarily as a result of lower volumes described above. Newport News cost of service revenues increased $14 million for the three months ended March 31, 2021, primarily as a result of the volume increases described above. Technical Solutions cost of service revenues decreased $94 million for the three months ended March 31, 2021, primarily as a result of the lower volumes described above and year-to-year variances in contract mix. Cost of service revenues related to the Operating FAS/CAS Adjustment increased $19 million for the three months ended March 31, 2021, as described below.

Cost of service revenues as a percentage of service revenues increased from 86.1% for the three months ended March 31, 2020, to 86.5% for the three months ended March 31, 2021, primarily driven by an unfavorable change in the Operating FAS/CAS Adjustment, partially offset by improved performance on DFS services and year-to-year variances in contract mix.

Income (Loss) from Operating Investments, Net

The activities of our operating investments are closely aligned with the operations of the segments holding the investments. We therefore record income related to earnings from equity method investments in our operating income.

Table of Contents

Income from operating investments, net for the three months ended March 31, 2021, increased $2 million from the same period in 2020, primarily due to higher equity income from our nuclear and environmental joint ventures.

Other Income and Gains

For the three months ended March 31, 2021, we recognized a $3 million gain on the sale of our oil and gas business.

General and Administrative Expenses

In accordance with industry practice and the regulations that govern the cost accounting requirements for government contracts, most general and administrative expenses are considered allowable and allocable costs on government contracts. These costs are allocated to contracts in progress on a systematic basis, and contract performance factors include this cost component as an element of cost.

General and administrative expenses for the three months ended March 31, 2021, decreased $8 million from the same period in 2020, primarily driven by favorable changes in current state income tax expense and lower overhead costs.

Operating Income

We consider operating income to be an important measure for evaluating our operating performance, and, consistent with industry practice, we define operating income as revenues less the related cost of producing the revenues and general and administrative expenses.

We internally manage our operations by reference to "segment operating income," which is defined as operating income before the Operating FAS/CAS Adjustment and non-current state income taxes, neither of which affects segment performance. Segment operating income is not a recognized measure under GAAP. When analyzing our operating performance, investors should use segment operating income in addition to, and not as an alternative for, operating income or any other performance measure presented in accordance with GAAP. It is a measure we use to evaluate our core operating performance. We believe segment operating income reflects an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our business. We believe the measure is used by investors and is a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of segment operating income may not be comparable to similarly titled measures of other companies.

The following table reconciles operating income to segment operating income:


	Three Months Ended March 31
					2021 over 2020
($ in millions)	2021		2020		Dollars		Percent
Operating income	$	147	$	215	$	(68)	(32)	%
Operating FAS/CAS Adjustment	40		(63)		103		163	%
Non-current state income taxes	4		4		—		—	%
Segment operating income	$	191	$	156	$	35	22	%

Segment Operating Income

Segment operating income for the three months ended March 31, 2021, was $191 million, compared with segment operating income of $156 million for the same period in 2020. The increase was primarily driven by higher risk retirement on Bougainville (LHA 8) and on Block IV of the Virginia class (SSN 774) submarine program, improved performance on DFS services and nuclear and environmental services, partially offset by lower risk retirement on the RCOH of USS George Washington (CVN 73).

Activity within each segment is discussed in Segment Operating Results below.

FAS/CAS Adjustment and Operating FAS/CAS Adjustment

The FAS/CAS Adjustment reflects the difference between expenses for pension and other postretirement benefits determined in accordance with GAAP ("FAS") and the expenses for these items included in segment operating income in accordance with U.S. Cost Accounting Standards ("CAS"). The Operating FAS/CAS Adjustment excludes the following components of net periodic benefit costs: interest cost, expected return on plan assets, amortization of prior service cost (credit) and actuarial loss (gain), and settlement and curtailment effects.

Effective January 1, 2021, we adopted the Safe Harbor methodology used in determining CAS pension costs. Under the new methodology, the interest rates used to calculate pension liabilities under CAS are consistent with

those used in the determination of minimum funding requirements under the Employee Retirement Income Security Act of 1974 ("ERISA").

The components of the Operating FAS/CAS Adjustment were as follows:


	Three Months Ended March 31
					2021 over 2020
($ in millions)	2021		2020		Dollars		Percent
FAS expense	$	(7)	$	(17)	$	10	59	%
CAS cost	13		110		(97)		(88)	%
FAS/CAS Adjustment	6		93		(87)		(94)	%
Non-operating retirement benefit	(46)		(30)		(16)		(53)	%
Operating FAS/CAS Adjustment	$	(40)	$	63	$	(103)	(163)	%

The Operating FAS/CAS Adjustment was a net expense of $40 million and a net benefit of $63 million for the three months ended March 31, 2021 and 2020, respectively. The unfavorable change in the Operating FAS/CAS Adjustment from 2020 to 2021 was primarily driven by the more immediate recognition of higher interest rates under CAS.

Non-current State Income Taxes

Non-current state income taxes include deferred state income taxes, which reflect the change in deferred state tax assets and liabilities, and the tax expense or benefit associated with changes in state unrecognized tax benefits in the relevant period. These amounts are recorded within operating income. Current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Non-current state income tax expense was $4 million for each of the three months ended March 31, 2021 and 2020.

Interest Expense

Interest expense for the three months ended March 31, 2021, increased $5 million, compared with the same period in 2020, primarily due to interest on senior notes issued in 2020.

Non-Operating Retirement Benefit

The non-operating retirement benefit includes the following components of net periodic benefit costs: interest cost, expected return on plan assets, amortization of prior service cost (credit) and actuarial loss (gain), and settlement and curtailment effects. For the three months ended March 31, 2021, the favorable change in the non-operating retirement benefit of $16 million, was primarily driven by higher 2020 returns on plan assets.

Other, Net

Other, net income increased $14 million for the three months ended March 31, 2021, compared with the same period in 2020, primarily driven by gains on investments in marketable securities and interest income.

Federal and Foreign Income Taxes

Our effective income tax rates on earnings from operations for the three months ended March 31, 2021 and 2020, were 14.5% and 20.4%, respectively. The lower effective tax rate for the three months ended March 31, 2021, was primarily attributable to the tax loss associated with the sale of our oil and gas business resulting in a reduction in the effective tax rate of 5.5%.

For the three months ended March 31, 2021, our effective tax rate differed from the federal statutory tax rate primarily as a result of the tax loss associated with the sale of our oil and gas business. For the three months ended March 31, 2020, our effective tax rate did not differ materially from the federal statutory corporate income tax rate of 21%. See Note 11: Income Taxes.

KEY SEGMENT FINANCIAL MEASURES

Sales and Service Revenues

Period-to-period revenues reflect performance under new and ongoing contracts. Changes in sales and service revenues are typically expressed in terms of volume. Unless otherwise described, volume generally refers to increases (or decreases) in reported revenues due to varying production activity levels, delivery rates, or service levels on individual contracts. Volume changes will typically carry a corresponding income change based on the margin rate for a particular contract.

Segment Operating Income (Loss)

Segment operating income reflects the aggregate performance results of contracts within a segment. Excluded from this measure are certain costs not directly associated with contract performance, such as the Operating FAS/CAS Adjustment and non-current state income taxes. Changes in segment operating income are typically expressed in

Table of Contents

terms of volume, as discussed above, or performance. Performance refers to changes in contract margin rates. These changes typically relate to profit recognition associated with revisions to estimated costs at completion ("EAC") that reflect improved or deteriorated operating performance on that contract. Operating income changes are accounted for on a cumulative to date basis at the time an EAC change is recorded. Segment operating income may also be affected by, among other things, contract performance, the effects of workforce stoppages, the effects of natural disasters such as hurricanes, resolution of disputed items with the customer, recovery of insurance proceeds, and other discrete events. At the completion of a long-term contract, any originally estimated costs not incurred or reserves not fully utilized, such as warranty reserves, could also impact contract earnings. Where such items have occurred and the effects are material, a separate description is provided.

Cumulative Adjustments

For the three months ended March 31, 2021 and 2020, favorable and unfavorable cumulative catch-up margin adjustments were as follows:


	Three Months Ended March 31

($ in millions)	2021		2020
Gross favorable adjustments	$	86	$	61
Gross unfavorable adjustments	(36)		(29)
Net adjustments	$	50	$	32

For the three months ended March 31, 2021, favorable cumulative catch-up adjustments were related to risk retirement on Bougainville (LHA 8) and Block IV of the Virginia class (SSN 774) submarine program. During the same period, none of the unfavorable cumulative catch-up margin adjustments were individually significant.

For the three months ended March 31, 2020, favorable cumulative catch-up adjustments were related to risk retirement on the Virginia class (SSN 774) submarine program, the RCOH of USS George Washington (CVN 73), the San Antonio class (LPD 17) program, and other individually insignificant adjustments. During the same period, none of the unfavorable cumulative catch-up adjustments were individually significant.

Sales and Service Revenues

Ingalls revenues for the three months ended March 31, 2021, increased $20 million, or 3%, from the same period in 2020, primarily driven by higher revenues in surface combatants, partially offset by lower revenues in the Legend class NSC program. Surface combatant revenues increased due to higher volumes on George M. Neal (DDG 131), Jeremiah Denton (DDG 129), and Jack H. Lucas (DDG 125), partially offset by lower volumes on USS Fitzgerald (DDG 62) restoration and modernization following its redelivery and Delbert D. Black (DDG 119) following its delivery. Revenues on the Legend class NSC program decreased due to lower volumes on Stone (NSC 9) following its delivery. Amphibious assault ship revenues were flat as a result of higher volumes on Pittsburgh (LPD 31), Bougainville (LHA 8), and LHA 9 (unnamed), partially offset by lower volumes on Richard M. McCool Jr. (LPD 29), Fort Lauderdale (LPD 28), and USS Tripoli (LHA 7).

Table of Contents

Segment Operating Income

Ingalls segment operating income for the three months ended March 31, 2021, was $91 million, compared with $68 million for the same period in 2020. The increase was primarily driven by higher risk retirement on Bougainville (LHA 8).

Sales and Service Revenues

Newport News revenues for the three months ended March 31, 2021, increased $66 million, or 5%, from the same period in 2020, primarily driven by higher revenues in aircraft carriers, naval nuclear support services, and submarines. Aircraft carrier revenues increased primarily as a result of higher volumes on Enterprise (CVN 80), the RCOH of USS John C. Stennis (CVN 74), and Doris Miller (CVN 81), partially offset by lower volumes on Kennedy (CVN 79) and the RCOH of USS George Washington (CVN 73). Naval nuclear support services revenues increased primarily as a result of higher volumes in carrier and submarine fleet support services, offset by lower volume in facility maintenance services. Submarine revenues increased primarily as a result of higher volumes on the Columbia class submarine program and the Virginia class (SSN 774) submarine program. The higher volume on the Virginia class (SSN 774) submarine program was due to higher volumes on Block V boats, offset by lower volumes on Block IV boats.

Segment Operating Income

Newport News segment operating income for the three months ended March 31, 2021, was $93 million, compared with segment operating income of $95 million for the same period in 2020. The decrease was primarily due to lower risk retirement on the RCOH of USS George Washington (CVN 73), partially offset by higher risk retirement on Block IV of the Virginia class (SSN 774) submarine program.

Technical Solutions

Sales and Service Revenues

Technical Solutions revenues for the three months ended March 31, 2021, decreased $58 million, or 18%, from the same period in 2020, primarily due to the divestitures of our oil and gas business and San Diego Shipyard, as well as lower volumes in DFS services, partially offset by the acquisition of Hydroid in March 2020.

Table of Contents

Segment Operating Income (Loss)

Technical Solutions segment operating income for the three months ended March 31, 2021, was $7 million, compared with a loss of $7 million for the same period in 2020. The increase was primarily driven by improved performance on DFS services and nuclear and environmental services, as well as a gain on the sale of our oil and gas business.

BACKLOG

Total backlog as of March 31, 2021, and December 31, 2020, was approximately $48.8 billion and $46.0 billion, respectively. Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog (firm orders for which funding is not currently contractually obligated by the customer). Backlog excludes unexercised contract options and unfunded IDIQ orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer.

The following table presents funded and unfunded backlog by segment as of March 31, 2021, and December 31, 2020:


	March 31, 2021						December 31, 2020
					Total						Total
($ in millions)	Funded		Unfunded		Backlog		Funded		Unfunded		Backlog
Ingalls	$	10,516	$	1,687	$	12,203	$	10,443	$	1,758	$	12,201
Newport News	13,321		22,247		35,568		9,536		23,132		32,668

Total backlog	$	24,591	$	24,238	$	48,829	$	20,481	$	25,536	$	46,017

Approximately 16% of the $46.0 billion total backlog as of December 31, 2020, is expected to be converted into sales in 2021. U.S. Government orders comprised substantially all of the backlog as of March 31, 2021, and December 31, 2020.

Awards

The value of new contract awards during the three months ended March 31, 2021, was approximately $5.3 billion, comprised primarily of awards for the RCOH of the USS John C. Stennis (CVN 74), construction of a 10th boat of the Virginia class (SSN 774) submarine program, and construction of John F. Lehman (DDG 137).

LIQUIDITY AND CAPITAL RESOURCES

We seek to efficiently convert operating results into cash for deployment in operating our businesses, implementing our business strategy, and maximizing stockholder value. We use various financial measures to assist in capital deployment decision making, including net cash provided by operating activities and free cash flow. We believe these measures are useful to investors in assessing our financial performance.

Table of Contents

The following table summarizes key components of cash flow provided by operating activities:


	Three Months Ended March 31				2021 over 2020

($ in millions)	2021		2020		Dollars
Net earnings	$	148	$	172	$	(24)

Net cash provided by operating activities	$	43	$	68	$	(25)

Cash Flows

We discuss below our major operating, investing, and financing activities for the three months ended March 31, 2021 and 2020, as classified on our unaudited condensed consolidated statements of cash flows.

Operating Activities

Cash provided by operating activities for the three months ended March 31, 2021, was $43 million, compared with $68 million provided by operating activities for the same period in 2020. The unfavorable change in operating cash flow was primarily due to higher contributions to retiree benefit plans, partially offset by a federal income tax refund and changes in trade working capital. The change in trade working capital was primarily driven by the timing of receipts of accounts receivable and payments of accounts payable.

For the three months ended March 31, 2021, we made discretionary contributions to our qualified defined benefit pension plans totaling $60 million, compared with $20 million of discretionary contributions for the same period in 2020. As of March 31, 2021, we anticipate no further significant cash contributions to our qualified defined benefit pension plans in 2021.

We expect cash generated from operations in combination with our current cash and cash equivalents, as well as existing credit facilities, to be sufficient to service debt and retiree benefit plans, meet contractual obligations, and finance capital expenditures for at least the next 12 months.

Investing Activities

Cash used in investing activities for the three months ended March 31, 2021, was $46 million, compared with $444 million used in investing activities for the same period in 2020. The change in investing cash was driven by the acquisition of Hydroid in 2020, disposition of our oil and gas business in 2021, and lower capital expenditures in 2021, partially offset by the acquisition of a non-controlling interest in Titan in 2021. For 2021, we expect our capital expenditures for maintenance and sustainment to be approximately 1.0% of annual revenues and our discretionary capital expenditures to be approximately 2.0 % to 3.0% of annual revenues.

Financing Activities

Cash used in financing activities for the three months ended March 31, 2021, was $102 million, compared with $329 million provided by financing activities for the same period in 2020. The change in financing cash was primarily due to a decrease in net proceeds from revolving credit facility borrowings of $380 million, a decrease of net proceeds from issuances of commercial paper of $88 million, and a $4 million increase in cash dividend payments, partially offset by a decrease of $35 million from common stock repurchases and a decrease of $6 million in employee taxes on certain share-based payment arrangements.

Table of Contents

Free Cash Flow

Free cash flow represents cash provided by (used in) operating activities less capital expenditures net of related grant proceeds. Free cash flow is not a measure recognized under GAAP. Free cash flow has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, analysis of our results as reported under GAAP. We believe free cash flow is an important liquidity measure for our investors because it provides them insight into our current and period-to-period performance and our ability to generate cash from continuing operations. We also use free cash flow as a key operating metric in assessing the performance of our business and as a key performance measure in evaluating management performance and determining incentive compensation. Free cash flow may not be comparable to similarly titled measures of other companies.

The following table reconciles net cash provided by operating activities to free cash flow:


	Three Months Ended March 31				2021 over 2020

($ in millions)	2021		2020		Dollars
Net cash provided by operating activities	$	43	$	68	$	(25)
Less capital expenditures:
Capital expenditure additions	(60)		(71)		11
Grant proceeds for capital expenditures	1		5		(4)
Free cash flow	$	(16)	$	2	$	(18)

Free cash flow for the three months ended March 31, 2021, decreased $18 million from the same period in 2020, primarily due to higher contributions to retiree benefit plans, partially offset by a federal income tax refund, changes in trade working capital, and lower capital expenditures.

Governmental Regulation and Supervision

The U.S. Government has the ability, pursuant to regulations relating to contractor business systems, to decrease or withhold contract payments if it determines significant deficiencies exist in one or more such systems. As of March 31, 2021 and 2020, the cumulative amounts of payments withheld by the U.S. Government under our contracts subject to these regulations were not material to our liquidity or cash flows.

Off-Balance Sheet Arrangements

In the ordinary course of business, we use letters of credit issued by commercial banks to support certain leases, insurance policies, and contractual performance obligations, as well as surety bonds issued by insurance companies principally to support our self-insured workers' compensation plans. As of March 31, 2021, $15 million in letters of credit were issued but undrawn and $272 million of surety bonds were outstanding. As of March 31, 2021, we had no other significant off-balance sheet arrangements.

GLOSSARY OF PROGRAMS

Included below are brief descriptions of some of the programs discussed in this Quarterly Report on Form 10-Q.


Program Name						Program Description

America class (LHA 6) amphibious assault ships						Design and build large deck amphibious assault ships that provide forward presence and power projection as an integral part of joint, interagency and multinational maritime expeditionary forces. The America class (LHA 6) ships, together with the Wasp class (LHD 1) ships, are the successors to the decommissioned Tarawa class (LHA 1) ships. The America class (LHA 6) ships optimize aviation operations and support capabilities. We delivered USS Tripoli (LHA 7) in February 2020, and we are currently constructing Bougainville (LHA 8).

Arleigh Burke class (DDG 51) destroyers						Build guided missile destroyers designed for conducting anti-air, anti-submarine, anti-surface, and strike operations. The Aegis-equipped Arleigh Burke class (DDG 51) destroyers are the U.S. Navy's primary surface combatant, and have been constructed in variants, allowing technological advances during construction. In 2019 we delivered USS Paul Ignatius (DDG 117), and in 2020 we delivered USS Delbert D. Black (DDG 119). We have contracts to construct the following Arleigh Burke class (DDG 51) destroyers: Frank E. Petersen Jr. (DDG 121), Lenah H. Sutcliffe Higbee (DDG 123), Jack H. Lucas (DDG 125), Ted Stevens (DDG 128), Jeremiah Denton (DDG 129), George M. Neal (DDG 131), Sam Nunn (DDG 133), Thad Cochran (DDG 135), and John F. Lehman (DDG 137).

Carrier RCOH						Perform refueling and complex overhaul ("RCOH") of nuclear-powered aircraft carriers, which is required at the mid-point of their 50-year life cycle. USS Abraham Lincoln (CVN 72) was redelivered to the U.S. Navy in the second quarter of 2017 and USS George Washington (CVN 73) arrived at Newport News for the start of its RCOH in August 2017.

Columbia class (SSBN 826) submarines						Newport News is participating in designing the Columbia class submarine as a replacement for the current aging Ohio class nuclear ballistic missile submarines, which were first introduced into service in 1981. The Ohio class SSBN includes 14 nuclear ballistic missile submarines and four nuclear cruise missile submarines. The Columbia class program plan of record is to construct 12 new ballistic missile submarines. The U.S. Navy has initiated the design process for the new class of submarines, and, in early 2017, the DOD signed the acquisition decision memorandum approving the Columbia class program’s Milestone B, which formally authorizes the program’s entry into the engineering and manufacturing development phase. We perform design work as a subcontractor to Electric Boat, and we have entered into a teaming agreement with Electric Boat to build modules for the entire Columbia class (SSBN 826) submarine program that leverages our Virginia class (SSN 774) experience. We have been awarded contracts from Electric Boat to begin integrated product and process development and provide long-lead-time material and advance construction for the Columbia class (SSBN 826) program. Construction of the first Columbia class (SSBN 826) submarine began in 2020.

Defense and federal solutions						DFS is focused on solving tough national security challenges for the DoD, the intelligence community, and federal civilian agencies around the globe. The group’s expertise includes maritime fleet sustainment; intelligence, surveillance, and reconnaissance; cyber operations; secure enterprise information technology engineering and operations; advanced modeling, simulation, and training; and logistics management.

USS Gerald R. Ford class (CVN 78) aircraft carriers						Design and construction for the Ford class program, which is the aircraft carrier replacement program for the decommissioned Enterprise (CVN 65) and Nimitz class (CVN 68) aircraft carriers. USS Gerald R. Ford (CVN 78), the first ship of the Ford class, was delivered to the U.S. Navy in the second quarter of 2017. In June 2015, we were awarded a contract for the detail design and construction of John F. Kennedy (CVN 79), following several years of engineering, advance construction, and purchase of long-lead time components and material. In addition, we have received awards for detail design and construction of Enterprise (CVN 80) and Doris Miller (CVN 81). This category also includes the class' non-recurring engineering. The class is expected to bring improved warfighting capability, quality of life improvements for sailors, and reduced life cycle costs.

Legend class National Security Cutter						Design and build the U.S. Coast Guard's National Security Cutters ("NSCs"), the largest and most technically advanced class of cutter in the U.S. Coast Guard. The NSC is equipped to carry out maritime homeland security, maritime safety, protection of natural resources, maritime mobility, and national defense missions. The plan is for a total of 11 ships, of which the first nine ships have been delivered. Calhoun (NSC 10) and Friedman (NSC 11) are currently under construction.

Naval nuclear support services						Provide services to and in support of the U.S. Navy, ranging from services supporting the Navy's carrier and submarine fleets to maintenance services at U.S. Navy training facilities.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk, primarily related to interest rates and foreign currency exchange rates.

Interest Rates - Our financial instruments subject to interest rate risk include commercial paper and floating rate borrowings under our credit facility. As of March 31, 2021, our $1,250 million revolving credit facility was undrawn.

Foreign Currency - We currently have, and in the future may enter into, foreign currency forward contracts to manage foreign currency exchange rate risk related to payments to suppliers denominated in foreign currencies. As of March 31, 2021, the fair values of our outstanding foreign currency forward contracts were not significant.

Item 4. Controls and Procedures
