HUNTINGTON INGALLS INDUSTRIES, INC.
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
6

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.

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
9

Table of Contents                                        
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
11

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:

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.

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

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.

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. As
