ITEM 1. BUSINESS


History and Organization


Huntington Ingalls Industries, Inc. ("HII", the "Company", "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 Shipbuilding segment ("Ingalls") in Mississippi and Newport News Shipbuilding segment ("Newport News") in Virginia have built more ships in more ship classes than any other U.S. naval shipbuilder. Our Technical Solutions segment established in the fourth quarter of 2016, provides a range of services to the governmental, energy,government and oil and gas markets.commercial customers.


We conduct most of our business with the U.S. Government, primarily the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member, or partner, we participate in many high-priority U.S. defense technology 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. We also provide a wide range of professional services, including fleet support, integrated missionsdefense and federal solutions ("DFS"), nuclear and environmental services, and oil and gas servicesunmanned systems, through our Technical Solutions segment.

Headquartered in Newport News, Virginia, we employ approximately 38,00044,000 people operating both domestically and internationally. We became an independent, publicly-owned company in 2011, when we were spun off from Northrop Grumman.


Ingalls
 
Through our Ingalls segment, we design and construct non-nuclear ships for the U.S. Navy and U.S. Coast Guard, including amphibious assault ships, expeditionary warfare ships, surface combatants, and national security cutters ("NSC"). We are the sole builder of amphibious assault ships and one of two builders of surface combatants for the U.S. Navy. We are the sole builder of large multi-mission NSCs for the U.S. Coast Guard. Our Ingalls segment is located in Pascagoula, Mississippi on 800 acres along the Pascagoula River. This shipyard offers a collection of manufacturing capabilities that includes a 660-ton gantry crane and a Land Based Test Facility.


Amphibious Assault Ships
We construct amphibious assault ships and expeditionary warfare ships for the U.S. Navy, which include the U.S. Navy large deck amphibious assault ships ("LHA") and amphibious transport dock ships ("LPD")., respectively. The LHA is a key component of the U.S. Navy-Marine CorpsDepartment of the Navy's requirement for 11 Expeditionary Strike Groups/Amphibious Readiness Groups, and design, construction, and modernization of LHAs are core to our Ingalls operations. In 2007, we were awarded the construction contract for USS America (LHA 6), the first in a new class of enhanced amphibious assault ships designed from the keel up to be an aviation optimized Marine assault platform. We delivered USS AmericaTripoli (LHA 6)7) in the second quarter of 2014,2020 and are currently constructing Tripoli Bougainville (LHA 7), scheduled for delivery in 2018, and in 20168). In 2020, we were awarded thea long-lead-time material and construction contract for Bougainville (LHA 8)9 (unnamed).
The LPD program is a long-running production program of expeditionary warfare ships in which we have generated efficiencies through ship-over-ship learning.We delivered USS Portland (LPD 27) in the third quarter of 2017 and USS John P. Murtha (LPD 26) in 2016, and we are currently constructing Fort Lauderdale (LPD 28), scheduled for delivery in 2021.Richard M. McCool Jr. (LPD 29), and Harrisburg (LPD 30). In 20172020, we were awarded an advance procurementa contract for to construct Pittsburgh (LPD 29.31).



Surface Combatants
We are a design agent for, and one of only two companies that constructs, the Arleigh Burke class (DDG 51) guided missile destroyers, a class of surface combatant. We have delivered 30 33 Arleigh Burke class (DDG 51) destroyers to the U.S. Navy, including Ralph Johnson (DDG 114)Frank E. Petersen Jr. (DDG 121) in the fourth quarter of 20172021, USS Delbert D. Black (DDG 119) in 2020, and USS John FinnPaul Ignatius (DDG 113)117) in 2016.2019. In 2013, we were awarded a multi-year contract totaling $3.3 billion for construction of five additional Arleigh Burke class (DDG 51) destroyers, as a part of a larger U.S. Navy order for nine Arleigh Burke class (DDG 51)destroyers.which three have been delivered. We are currently constructing Paul Ignatius (DDG 117),Delbert D. Black (DDG 119), Frank E. Petersen Jr. (DDG 121), the remaining two ships: Lenah H. Sutcliffe Higbee (DDG 123), and Jack H. Lucas (DDG 125), with deliveries scheduled in. In 2018, 2019,we were awarded a multi-year contract totaling $5.1 billion for construction of six additional Arleigh Burke class (DDG 51) destroyers. In 2020, 2021 and 2023, respectively.we were awarded a contract to construct an additional Arleigh Burke class (DDG 51) destroyer.

National Security Cutters
The U.S. Coast Guard's recapitalization program is designed to replace aging and operationally expensiveexpansive ships and aircraft used to conduct missions in excess of 50 miles from the shoreline. The flagship of this program is the Legend class NSC, a multi-mission platform we designed and continue to build. We delivered USCGC HamiltonKimball (NSC 4)7), USCGC James (NSC 5)Midgett (NSC 8), and USCGC Munro (NSC 6)Stone (NSC 9) to the U.S. Coast Guard in 2014, 2015, and 2016, respectively. Kimball (NSC 7), Midgett (NSC 8) and Stone (NSC 9) are currently under construction and scheduled for delivery in 2018, 2019, and 2020, respectively. In 2018, we were awarded long-lead-time material and construction contracts for Calhoun (NSC 10) and Friedman (NSC 11), which are currently under construction.


Newport News


The core business of our Newport News segment is designing and constructing nuclear-powered ships, such as aircraft carriers and submarines, and the refueling and overhaul and the inactivation of such ships.nuclear-powered aircraft carriers. Our Newport News shipyard is located on approximately 550 acres near the mouth of the James River, which adjoins the Chesapeake Bay. The shipyard has two miles of waterfront property and heavy industrial facilities, which include seven graving docks, a floating dry dock, two outfitting berths, five outfitting piers, module outfitting facilities, and various other workshops. Our Newport News shipyard also has a 2,170-foot dry dock serviced by a 1,050-ton gantry crane capable of supporting two aircraft carriers at one time.
 
Design, Construction, Refueling and Complex Overhaul, and Inactivation of Aircraft Carriers


Engineering, design, and construction of U.S. Navy nuclear aircraft carriers ("CVN") are core to Newport News operations. Aircraft carriers are the largest ships in the U.S. Navy's fleet, with a displacement of over 90,000 tons. Newport News has designed and built more than 3031 aircraft carriers for the U.S. Navy since 1933, including all ten Nimitz class (CVN 68) aircraft carriers currently in active service, as well as the first ship of the next generation Gerald R. Ford class (CVN 78) aircraft carriers.
 
We delivered the U.S. Navy's newest carrier, USS Gerald R. Ford (CVN 78), in 2017. We also received awardsBeginning in 2009, through 2016we received contract awards totaling $7.6$7.8 billion for construction preparation, detail design, and construction of the second Gerald R. Ford class (CVN 78) aircraft carrier, John F. Kennedy (CVN 79),. In addition, we have received awards valued at $15.3 billion for detail design and awards totaling $392 million for advance planning and long-lead time material acquisition forconstruction of the third Gerald R. Ford class (CVN 78) aircraft carrier, carriers Enterprise (CVN 80) and Doris Miller (CVN 81).
We continue to be the exclusive prime contractor for nuclear aircraft carrier refueling and complex overhaul ("RCOH"). Each RCOH takes nearly four years to complete, with the work accounting for approximately 35% of all maintenance and modernization during an aircraft carrier's 50 year service life. RCOH services include propulsion work (refueling of reactors; propulsion plant modernization; and propulsion plant repairs), restoration of service life (dry docking, tank, and void maintenance; hull, shafting, propellers, and rudders; launch and recovery system; piping repairs; and component refurbishment), and modernization (electrical systems; aviation support systems; warfare; interoperability; and environmental compliance). We provide ongoing maintenance services for the U.S. Navy aircraft carrier fleet through both RCOH and fleet support across the globe.


In 2017, we completed the RCOH for USS Abraham Lincoln (CVN 72) and redelivered the ship to the U.S. Navy. We are currently performing the RCOH of USS George Washington (CVN 73) and USS John C. Stennis (CVN 74). We believe our position as the exclusive designer and builder of nuclear-powered aircraft carriers, our RCOH performance on the first six seven Nimitz class (CVN 68) carriers, and our highly trained workforce, as well as the fact thatcapital-intensive nature of RCOH work, is capital-intensive and has high barriers to entry due to its nuclear component strongly position us for RCOH contract awards on the remaining Nimitz class (CVN 68) carriers, as well as future RCOH work on Gerald R. Ford class (CVN 78) aircraft carriers.


The U.S. Navy awarded usWe received a $745 million contract in 2013 to inactivate the decommissioned Enterprise (CVN 65), the world's first nuclear-powered aircraft carrier, which was built by us and commissioned in 1961. The decommissioned Enterprise (CVN 65) inactivation is scheduled to bewas completed in the second quarter of 2018. Aircraft carriers have a lifespan of approximately 50 years, and we believe the ten Nimitz class (CVN 68) carriers we delivered by us that are currently in active service, as well as Gerald R. Ford class (CVN 78) aircraft carriers, we will deliver in the future, present a significant opportunityopportunities for inactivation contracts as they reach the end of their lifespans. We believe we are well positioned as the U.S. Navy's shipyard of choice for these contract awards.

Design and Construction of Nuclear-Powered Submarines
We are one of only two companies in the United States capable of designing and building nuclear-powered submarines for the U.S. Navy. Newport News has delivered 6062 submarines to the U.S. Navy since 1960, comprised of 4648 fast attack and 14 ballistic missile submarines. Of the 52 nuclear-powered fast attack submarines currently in active service, 25 were delivered by Newport News. Our nuclear submarine program, located at our Newport News shipyard, includes construction, engineering, design, research, and integrated planning.


In February 1997, we executedVirginia Class (SSN 774) Submarines

We have a teaming agreement with Electric Boat Corporation ("Electric Boat"), a division of General Dynamics Corporation ("General Dynamics"), to build Virginia class (SSN 774) fast attack nuclear submarines cooperatively.submarines. Under the presentteaming arrangement, we build the stern, habitability and machinery spaces, torpedo room, sail, and bow, while Electric Boat builds the engine room, control room, and pressure hull structure. Work on the reactor plant and the final assembly, test, outfit, and delivery of the submarines alternateto the U.S. Navy alternates between Electric Boat and us.


The four submarines of the first block and six submarines of the second block of Virginiaclass (SSN 774) submarines have been delivered. In December 2008, the team was awardedU.S. Navy signed a construction contract for the third block of eight Block III Virginiaclass (SSN 774) submarines. The multi-year contract increased construction fromrequired delivery of oneVirginia class (SSN 774) submarine per year for the first two years, and increased production to two submarines per year.year for the remaining six Block III boats. The first submarine under this contract was delivered in 2014, and the last submarine of the third block is scheduled for deliveryBlock III was delivered in 2019. In 2014, the team was awarded a construction contract for the fourth block of ten Virginia class (SSN 774) submarines. The first submarine of the Block IV contract was delivered in 2020, and the remaining boats are in the module outfitting, final assembly, and test phases of construction. In 2019, the team was awarded a construction contract for the fifth block of nine Virginiaclass (SSN 774) submarines, and, in 2021, an option for a 10th submarine was exercised, continuing the two submarines per year production rate.rate that began on the third block. The firstfiscal year 2021 appropriations act included funding for the 10th submarine in Block V, and the fiscal year 2022 National Defense Authorization Act recommends continued procurement of two Virginia class (SSN 774) submarines per fiscal year. All ten boats of the block IVBlock V contract is scheduled for deliveryare in 2019,the early manufacturing and the last is scheduled for delivery in 2023.advance procurement phases.


Columbia Class (SSBN 826) Submarines


Newport News is participating in designingdesign and construction of the Columbia class (SSBN 826) submarine as a replacement for the current aging Ohio class nuclear ballistic missile submarines ("SSBN"), which were first introduced into service in 1981. The Ohio class SSBN includes 14 nuclear ballistic missile submarines and four nuclear cruise missile submarines ("SSGN"). The Columbia class (SSBN 826) program currently anticipates 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 (SSBN 826) program’s Milestone B, which formally authorizes the program’s entry into the engineering and manufacturing development phase. We continue to 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. The teaming agreement is subject to the U.S. Navy's concurrence. Newport News wasWe were previously awarded a contractcontracts from Electric Boat in 2017 to begin integrated product and process development and provide long–lead-time material and advance construction for the Columbiaclass. Construction class (SSBN 826) program. Contract award for the first two Columbia class submarines (SSBN 826 and SSBN 827) and construction start of the first Columbiaclass (SSBN 826) submarine is expected to beginoccurred in 2021, with procurement of long-lead-time materials and advance construction beginning prior to that time.

Backlog


As of each of December 31, 20172021 and 2016,2020, our total backlog was approximately $21 billion.$48.5 billion and $46.0 billion, respectively. We expect approximately 31%19% of backlog at December 31, 2017,2021, to be converted into sales in 2018.2022.


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). Unfunded backlog excludes unexercised contract options and unfunded Indefinite Delivery/Indefinite Quantity orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer. Backlog is converted into sales as work is performed or deliveries are made. For backlog by segment, see Backlog in Item 7.

Raw Materials
The most significant material we use is steel. Other materials we use in large quantities include paint, aluminum, pipe, electrical cable, and fittings. All of these materials are currently available in adequate supply. In connection

with our U.S. Government contracts, we are required to procure certain materials and component parts from supply sources approved by the U.S. Government. Generally, forFor long-term contracts, we obtaingenerally solicit price quotations for many of our materialsmaterial requirements from multiple suppliers to ensure competitive pricing. While we have not generally been dependent upon any one supply source, we currently have only one supplier for certain component parts as a result of consolidation in the defense industry. We believe that these single source suppliers, as well as our overall supplier base, are adequate to meet our foreseeable needs. We have mitigated some supply risk by negotiating long-term agreements with certain raw material suppliers. In addition, we have mitigated price risk related to raw material purchases through certain contractual arrangements with customers.

We operate in a heavily regulated environmentare overseen and are routinely audited and reviewed by the U.S. Government and its agencies, including the U.S. Navy's Supervisor of Shipbuilding, the Defense Contract Audit Agency ("DCAA"), and the Defense Contract Management Agency ("DCMA"). These agencies evaluate our contract performance, cost structures, and compliance with applicable laws, regulations, and standards, as well as the adequacy of our business systems and processes relative to U.S. Government requirements. Business systems subject to audit or review include our accounting systems, purchasing systems, billing systems, property management and control systems, cost estimating systems, earned value management systems, compensation systems, and management information systems. If an audit uncovers improper or illegal activities, we may be subject to administrative, civil, or criminal proceedings, which could result in fines, penalties, repayments, or compensatory, treble, or other damages. Certain U.S. Government findings against a contractor can also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. In addition, any costs we incur that are determinedprivileges.

Our business systems subject to be unallowableaudit or improperly allocated to a specific contract will not be recovered or must be refunded if already reimbursed.

review include our accounting systems, purchasing systems, government property management systems, estimating systems, earned value management systems, and material management accounting systems. The U.S. Government has the ability to decrease or withhold contract payments if it determines significant deficiencies exist in one or more of our business systems subject to its review. In the past, thesystems. The U.S. Government has, in certain instances, withheld contract payments upon its assessment that significant deficiencies existedexist with one or more of our business systems. When appropriate, we must modifyAlthough this has not materially impacted the timing of our affected business systems to addresscash receipts in the past, any such action by the U.S. Government's determinations.Government in the future could have a material impact on the timing of our cash receipts.

The U.S. Government generally has the ability to terminate contracts, in whole or in part, with little or no prior notice, for convenience or for default based onupon performance. In the event of termination of a contract for convenience, a contractor is normally able to recover costs already incurred on the contract and receive profit on thoseincurred costs up to the amount authorized under the contract, but not the anticipated profit that would have been earned had the contract been completed. Such a termination could also result in the cancellation of future work on

the related program. TerminationA termination resulting from our default could expose us to various liabilities, including excess reprocurementre-procurement costs, and could have a material effect on our ability to compete for future contracts.


Government contractors must comply with significant regulatory requirements, including those related to procurement. Our contracts with the U.S. Government maysometimes result in Requests for Equitable Adjustments ("REAs"), which represent requests for the U.S. Government to make appropriate adjustments to contract terms, including pricing, delivery schedule, technical requirements, or other affected terms, due to changes in the original contract requirements and resulting delays and disruption in contract performance for which the U.S. Government is responsible. We prepare, submit and negotiate REAs in the ordinary course of business, and large REAs are not uncommon

at the conclusion of both new construction and RCOH activities. Such REAs are not consideredcan result in claims under the Contract Disputes Act of 1978, although they may be converted to such claims if good faith negotiations to resolve the REAs are not satisfactory.
Inin cases where there are multiple suppliers, contracts for the construction and conversion of U.S. Navy ships and submarines are generally subject to competitive bidding. In evaluating proposed prices,in which we cannot reach agreement with the U.S. Navy sometimes requires that each bidder submit information on pricing, estimated costs of completion, and anticipated profit margins to enable the Navy to assess cost realism. The U.S. Navy uses this information and other data to determine an estimated cost for each bidder. Under Government.
U.S. Government regulations determine contractor costs that are allowable and therefore recoverable from the government, and certain costs including certain financing costs and marketing expenses, are not allowable contract costs and therefore are not recoverable. The U.S. Government also regulates the methods by which all allowable costs, including overhead, are allocated to government contracts. Costs we incur that are not allowable under the Federal Acquisition Regulation (the “FAR”) or U.S. Cost Accounting Standards (“CAS”) or that are otherwise determined to be unallowable or improperly allocated to a specific contract will not be recovered or must be refunded if already reimbursed.
Our business, ourincluding contracts with various agencies of the U.S. Government agencies and our subcontracts with other prime contractors, are subject to a variety of laws and regulations, including but not limited to, the FAR, the Defense Federal Acquisition Regulation Supplement ("FAR"DFARS"), the Truth in Negotiations Act, the Procurement Integrity Act, the False Claims Act, Cost Accounting Standards,CAS, the International Traffic in Arms Regulations promulgated under the Arms Export Control Act, the Close the Contractor Fraud Loophole Act, and the Foreign Corrupt Practices Act. A noncompliance determination by a government agency may result in reductions in contract values, contract modifications or terminations, penalties, fines, repayments, compensatory, treble, or other damages, or suspension or debarment. We are also subject to evolving cyber security and data privacy and protection laws and regulations, which increase our costs and compliance risks and may affect our competitiveness, cause reputational harm, and expose us to damage claims, substantial fines, and other penalties.


Nuclear
Competition

Our nuclear operations are subject to various safety related requirements imposed by the U.S. Navy, the DoE, and the U.S. Nuclear Regulatory Commission. In the event of noncompliance, these agencies may increase regulatory oversight, impose fines, or shut down our operations, depending on their assessment of the severity of the noncompliance. In addition, new or revised security and safety requirements imposed by the U.S. Navy, the DoE, and the Nuclear Regulatory Commission could necessitate substantial capital and other expenditures.

Subject to certain requirements and limitations, our contracts with the U.S. Navy and the DoE generally provide for indemnity by the U.S. Government for losses resulting from our nuclear operations. For our commercial nuclear operations, we rely primarily on insurance carried by nuclear facility operators for risk mitigation, and we maintain limited insurance coverage for losses in excess of the coverage of facility operators.

Environmental

Our operations are subject to federal, state, and local laws and regulations relating to the protection of the environment. Substantial fines, penalties, and criminal sanctions may be imposed for noncompliance, and certain environmental laws impose joint and several "strict liability" for remediation of spills and releases of oil and hazardous substances. Such laws and regulations impose liability upon a party for environmental cleanup and remediation costs and damage without regard to negligence or fault on the part of such party and could expose us to liability for the conduct of or conditions caused by third parties.

We accrue estimated costs to perform environmental remediation when we determine it is probable we will incur expenses in the future, in amounts we can reasonably estimate, to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where we are named a Potentially Responsible Party ("PRP") by the U.S. Environmental Protection Agency ("EPA") or similarly designated by another environmental agency. Uncertainties regarding the extent of required remediation, determination of legally responsible parties, and the status of laws and regulations and their interpretations make future environmental remediation costs difficult to estimate and can cause our estimated remediation costs to change.

We believe we are in material compliance with environmental laws and regulations, and historical environmental compliance costs have not been material to our business. We could be affected by new environmental laws or regulations, including any laws and regulations enacted in response to concerns over climate change, other aspects of the environment, or natural resources. We have made investments we believe are necessary to comply with environmental legal requirements, but we expect to incur future capital and operating costs to comply with current and future environmental laws and regulations. We do not currently believe such costs will have a material effect on our financial position, results of operations, or cash flows.

Competitive Environment

In our primary business of designing, building, overhauling, and repairing military ships, we primarily compete with General Dynamics and, to a lesser extent,in the case of certain non-nuclear shipbuilding programs, smaller shipyards. The smaller shipyards one or more of which couldsometimes team with a large defense contractor.contractors. Intense competition related to programs, resources, and funding, and long operating cycles are key characteristics of both our shipbuilding business and the shipbuilding defense industry in general. It is common industry practice to share work on major programs among a number of companies. A company competing to be a prime contractor may, upon ultimate award of the contract to another party, become a subcontractor for the prime contracting party. It is not uncommon to compete for a contract award with a peer company and, simultaneously, performserve as a supplier to or a customer of such competitor on other contracts. The nature of major defense programs, conducted under binding long-term contracts, allows companies that perform well to benefit from a level of program continuity not common in many industries.


We believe we are well-positioned in our shipbuilding markets. Because we are the only company currently capable of building, refueling, and inactivating the U.S. Navy's nuclear-powered aircraft carriers, we believe we are in a strong competitive position to be awarded each contract to perform such activities. Even so, the government periodically revisits whether refueling of nuclear-powered aircraft carriers should be performed in private or public facilities. If a U.S. Government owned shipyard were to become capable and engaged in the refueling of nuclear-powered aircraft carriers, our market position could be significantly and adversely affected.


AlthoughWhile we have competed with another large defense contractor to construct abuild large deck amphibious ship, which was awarded to us,ships, we are currently the only builder of large deck amphibious assault ships and expeditionary warfare ships for the U.S. Navy, including LHAs and LPDs. We are also the sole builder of NSCs for the U.S. Coast Guard and strongly positioned to be awarded future contracts for these types of vessels.Guard. We are one of only two companies currently capable of designing and building nuclear-powered submarines for the U.S. Navy, and we are party to a long-term teaming agreementagreements with the other company for the production of such vessels.both Virginia class (SSN 774) fast attack nuclear submarines and Columbia class (SSBN 826) ballistic missile submarines. We are one of only two companies that builds the U.S. Navy's current fleet of Arleigh Burke class (DDG 51) destroyers and are strongly positioned to be awarded future contracts for these types ofsurface combatant ships as well.



Our Technical Solutions segment delivers technology-based products and solutions to government and commercial services markets, in which we compete with a wide range of companies supporting the U.S. government and its allies worldwide.

Our success in the shipbuilding defense industry depends upon our ability to develop, market, and produce our products and services at a costcosts consistent with the U.S. Navy's budget,our customers' expectations, as well as our ability to provide the workforce, technologies, facilities, equipment, and financial capacity needed to deliver those products and services with maximum efficiency.


Human Capital Resources

We compete withrecognize that our employees are our most important assets and serve as the foundation for our ability to achieve financial and strategic objectives. Our employees are critical to driving operational execution, meeting customer expectations, providing strong financial performance, advancing innovation, and maintaining a variety of companies in the provision of services to the government, energy,strong quality and oil and gas markets.

Environmental, Health, and Safety

compliance program. Our manufacturing operations are subject to and affected by federal, state, and local laws and regulations relating to the protection of the environment. We accrue estimated costs to complete environmental remediation when we determine it is probable we will incur expenses in the future, in amounts we can reasonably estimate, to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where we are named a Potentially Responsible Party ("PRP") by the U.S. Environmental Protection Agency ("EPA") or similarly designated by another environmental agency. The inherent difficulties in estimating future environmental remediation costs, resulting from uncertainties regarding the extent of required remediation, determination of legally responsible parties, and the status of laws and regulations and their interpretations, can cause our estimated remediation costs to change.

We assess the potential impact on our financial statements of future environmental remediation costs by estimating, on a site-by-site basis, the range of reasonably possible remediation costs that we could incur, taking into account currently available information atleaders believe each site, the current state of technology, and our prior experience in remediating contaminated sites. We review our estimates periodically and adjust them to reflect changes in facts, technology, and legal circumstances. We record accruals for environmental remediation costs on an undiscounted basis in the accounting period in which it becomes probable we have incurred a liability and the costs can be reasonably estimated. We would record related insurance recoveries only when we determine that collection is probable, and we do not include any litigation costs related to environmental matters in our environmental remediation accrual.

We either expense or capitalize environmental expenditures as appropriate. Capitalized expenditures relate to long-lived improvements in current operating facilities. We accrue environmental remediation costs at sites involving multiple parties based upon our expected share of liability, taking into account the financial viability of other jointly liable parties. We may incur remediation costs exceeding our accrued amount if other PRPs do not pay their allocable share of remediation costs, which could have a material effect on our business, financial position, results of operations, or cash flows.

As of December 31, 2017, our probable future costs for environmental remediation were approximately $1 million, which were accrued in other current liabilities in the consolidated statement of financial position. Although information gained as projects progress may materially affect our accrued liability, we do not anticipate that future remediation expenditures will have a material effect on our financial position, results of operations, or cash flows.

In October 2014, we ceased shipbuilding construction operations at our Avondale, Louisiana shipyard ("Avondale"). We may incur additional environmental costs in the future relatedemployee contributes to our wind down of shipbuilding at Avondale. Any additional costs are not reasonably estimable at this time due to insufficient information about the nature, timing, and extent of any potential environmental remediation we may be required to perform or the related costs that we may incur. Accordingly, such potential environmental costs associated with the wind down of Avondale are not included in our $1 million accrual for environmental remediation costs or otherwise reflected in our consolidated financial statements. We expect that a significant portion of any future environmental remediation costs we might incur at Avondale would be recoverable in accordance with government accounting practices under the FAR.success.
We believe we are in material compliance with environmental laws and regulations, and historical environmental compliance costs have not been material to our business. We could be affected by new environmental laws or regulations, including any enacted in response to concerns over climate change, other aspects of the environment, or natural resources. We have made investments we believe are necessary to comply with environmental laws, but we expect to continue to incur capital and operating costs in the future to comply with current and future environmental laws and regulations. At this time, we do not believe such costs will have a material effect on our financial position, results of operations, or cash flows.

With regard to occupational health and safety, the shipbuilding and ship repair industry involves work with hazardous materials and processes and remains one of the most hazardous industries. According to the Bureau of Labor Statistics, the shipbuilding and ship repair industry (NAICS 336611) ranks among the highest in several injury metrics. We have experienced one fatality in the past seven years. We strive to keep our Occupational Safety and Health Administration ("OSHA") compliance programs strong. In 1995, our Newport News shipyard became the first shipyard to be awarded the Star Award from OSHA's Voluntary Protection Program ("OSHA VPP"). To earn this award, we joined efforts with our unions and supported participation in the OSHA VPP, in which all parties assist each other to make our shipyard a safer place to work. Our CMSD facility has also been certified as an OSHA VPP Star Site.
The U.S. Navy, Nuclear Regulatory Commission, and DoE each regulate and control various matters relating to nuclear materials we handle. Subject to certain requirements and limitations, our contracts with the U.S. Navy and DoE generally provide for indemnity by the U.S. Government for losses resulting from our nuclear operations. For our commercial nuclear operations, we rely primarily on insurance carried by nuclear facility operators for risk mitigation, and we maintain limited insurance coverage for losses in excess of the coverage of facility operators.

Employees

We have approximately 38,00044,000 employees. We are the largest industrial employer in Virginia and the largest private employer in Mississippi. We employ individuals specializing in 19 crafts and trades, with approximately 5,4007,300 engineers and designers and approximately 2,4003,600 employees with advanced degrees. Our workforce contains many third-, fourth-, and fifth-generation employees, and approximately 1,4501,500 employees havewith more than 40 or more years of continuous service. Employees in our shipbuilding divisionssegments with more than 40 years of continuous service achieve the honor of “Master Shipbuilder.” As of December 31, 2017,2021, we had 1,0911,190 Master Shipbuilders at Newport News and 355284 at Ingalls. We also employ more than 6,0007,500 veterans across the enterprise.


More than 1,500In addition, over 900 apprentices are trained by our two shipbuilding units each yearenrolled in more than 27 crafts and advanced programs.programs at our two shipbuilding divisions. From nuclear pipe welders to senior executives, we employ approximately 4,500 apprentice school alumni, 3,000comprised of 3,061 at Newport News and 1,5001,487 at Ingalls.

Newport News craft workers employed at the Kesselring Site near Saratoga Springs, New York are represented under an indefinite DoE site agreement. Ingalls has five collective bargaining agreements covering represented employees, all of which expire in March 2022.2026. Approximately 3515 Technical Solutions craft employees in Klamath Falls, Oregon are covered by a collective bargaining agreement that expires in June 2025.

We reached a tentative agreement with representatives of United Steelworkers (“USW”) Local 8888 (Newport News) members on a new labor agreement in November 2021, but the members of the bargaining unit declined to ratify the contract. The Newport News and USW negotiation teams continued negotiations and reached a tentative agreement on another labor agreement in January 2022. We expect the members of the bargaining unit to vote on the new agreement in the near future. The USW Local 8888 members are continuing to work under the terms and conditions of the expired collective bargaining agreement, but the members may call for a strike, or we may declare a lock-out, upon 48 hours notice. We cannot give any assurances that the tentative labor agreement will be ratified by the local bargaining unit or that a strike or lock-out will not occur.

We have not experienced a work stoppage in more than 22 years at the Hanford Site near Richland, WashingtonNewport News and more than 14 years at Ingalls. We are represented under an indefinite DoE site stabilization agreement. Wecommitted to working effectively with our existing unions and believe our relationship with our represented employees is satisfactory.


The success and growth of our business depends in large part on our ability to attract, retain, and develop a skilled and diverse workforce of talented and high-performing employees at all levels of our organization. To succeed in the markets in which we compete for labor, we have developed key workforce development, recruitment, and retention strategies and objectives that we focus on as part of the overall management of our business. These strategies and objectives form the pillars of our human capital management framework and are advanced through the following programs, policies, and initiatives:

Competitive Pay and Benefits - Our compensation programs are designed to ensure we have the ability to attract, retain, and motivate employees to achieve our objectives.
We provide employee base wages and salaries that are competitive and consistent with employee positions, skill levels, experience, knowledge, and geographic location.
We utilize nationally recognized surveys and outside compensation and benefits consulting firms to independently evaluate the effectiveness of our employee and executive compensation and benefit programs and to provide benchmarking against our peers within the industry.
The structure of our executive compensation programs balances incentive earnings for both short-term and long-term performance, and we align our executive long-term equity compensation metrics with long-term shareholder interests.
Employees are eligible for health insurance, paid and unpaid leaves, 401(k) plans, and life and disability/accident insurance coverage. We also offer a variety of benefits that allow employees to select the options that meet their needs, including: annual leave/paid time off; paid holidays, flexible work arrangements/schedules; telemedicine; parental leave; transgender medical coverage; and a wellness program that includes physical, mental, and financial wellness components. We also fund the operation of Family Health Centers near our two shipyards, which provide a full range of medical, lab, pharmacy, dental, physical therapy, and vision services.

Recruitment, Training, and Workforce Development - Our three segments hire thousands of employees each year. In 2021, we hired nearly 6,000 new employees. To help us meet this large demand for talent, we have worked to create, develop, and maintain multiple talent pipelines. One of the key components of our approach to workforce development is to “grow our own.” We operate two apprentice schools, one at Ingalls and one at Newport News. The Newport News Apprentice School was founded in 1919, and the Ingalls Apprentice School was founded in 1952.

The two apprentice schools combined have graduated over 14,000 graduates since their inceptions. The schools are nationally renowned and are critical to training both our craft/trades and technical workforces, as well as developing the future leaders of our company. The Ingalls Apprentice School has partnered with the Mississippi Gulf Coast Community College to permit their apprentices to earn credits toward an associate’s degree. The Newport News Apprentice School has partnered with two community colleges, as well as Old Dominion University, to enable apprentices to earn a bachelor’s degree in Mechanical Engineering, Electrical Engineering, or Modeling & Simulation.

In addition to operating our own apprentice schools, we have developed and nurtured multiple partnerships with state and local governments, pre-K education providers, primary/secondary school districts, community colleges, and four-year colleges and universities, as well as post-graduate institutions. We also make significant investments through monetary contributions, leadership time, and employee volunteer hours to support these critical partnerships.

We maintain effective partnerships with colleges and universities, military bases for transitioning veterans, and regional community colleges to enable us to recruit and hire engineering, IT, and other technical talent. Working closely with state and local government leaders, we have successfully facilitated local, regional, and state-wide workforce development and education initiatives that include pre-K programs, high school trades programs/talent development labs, pre-hire trades/technical community college programs, interns/co-ops with colleges and universities, adult trades programs, veterans and military spouses training programs, and unemployed/underemployed training programs.

We view our workforce development process as a “leadership factory” and have developed a robust and effective succession planning process that ensures continuity in our leadership ranks. Since our founding in 2011, we have followed our succession plans 80% of the time when replacing a vacancy in an existing vice president position, and we have filled 77% of newly created vice president positions with internal hires.

Environmental, Health & Safety (“EH&S”) - The health, safety, and well-being of our employees, together with protection of the environment in the communities in which we operate, is one of our core values and rooted in our culture across the enterprise. We prioritize, manage, and carefully track safety performance and integrate sound environmental, safety, and health practices to make a meaningful difference in every facet of our operations, particularly at our shipbuilding segments and at DoE sites on which Technical Solutions segment employees work.
Safety goals are included in operational metrics for purposes of the Newport News and Ingalls compensation programs. We also use a wide variety of training courses, pre-job “Take Five” crew talks, medical surveillance programs, and employee involvement efforts to keep our workforce focused on EH&S. At Newport News and Ingalls, a key component of our EH&S program is the utilization of health and safety teams, which are comprised of production and maintenance employees and front-line managers whose goal is to educate, engage, and empower our workforce toward a culture that strives to reduce injury, illness, and environmental impacts. We employ programs focused on identifying, reporting, and abating near misses and other programs that aim to recognize, evaluate, and control hazards.

We track several metrics related to occupational injuries as one of several methods to monitor our safety performance. One of the key metrics is Total Case Rate (“TCR”), which is the number of Occupational Safety and Health Administration ("OSHA") recordable injuries per 100 equivalent employees. The TCR for Newport News was 5.64 in 2021, 4.77 in 2020, and 4.67 in 2019, and the TCR at Ingalls was 6.26 in 2021, 6.35 in 2020, and 6.59 in 2019. Newport News also tracks Days Away, Restricted or Transferred (“DART”), which is the number of OSHA recordable cases in which the employee is unable to work, cannot work due to a restriction, or can work with a restriction as a result of an injury per 100 equivalent employees. DART at Newport News was 4.45 in 2021, 3.41 in 2020, and 3.01 in 2019. Ingalls tracks two other safety metrics: Lost Time Case Rate (“LTCR”), which is the number of employees that lost work time per 100 employees, and Lost Work Day Rate (“LWDR”), which is the number of lost workdays per 100 full-time employees. The LTCR and LWDR at Ingalls were 2.75 and 76.32, respectively, in 2021, 2.53 and 56.37, respectively, in 2020, and 2.39 and 56.82, respectively, in 2019.

In connection with the outbreak of COVID-19, the DoD designated Newport News and Ingalls as critical infrastructure industry. Our production and support workforce therefore continued in-person work at our facilities to provide vital products and services to our government customers, while many of our employees in support and administrative functions effectively worked remotely from mid-March 2020 until our employees generally returned to our facilities in May 2021. Prior to the COVID-19 pandemic, less than 400 of our employees regularly worked remotely, and at our peak, more than 11,300 employees were working remotely.

In response to the COVID-19 pandemic, we have implemented mitigation measures to protect our employees and customers and support appropriate health and safety protocols. For example, we perform on-site COVID-19 testing, provide on-site vaccinations for employees, perform extensive cleaning and sanitation services for our shops, ships, and offices, re-engineered how some work was performed in order to support social distancing requirements, and implemented broad work-from-home initiatives for employees in our support and administrative functions.

Corporate Values - We operate on a set of values that are shared with all employees: Integrity, Safety, Respect, Engagement, Responsibility, and Performance. "Always doing the right thing" is an essential belief at HII. That tone starts at the top and permeates through the culture of the company. It is a set of core values, standards, and behaviors that guide employee commitment to the highest ethical standards and serves as the underlying framework for all of our human capital strategies.

Advancing and Celebrating Diversity and Inclusion (“D&I”) - We believe we gain a key competitive advantage by building a workforce community that values contributions and perspectives from a variety of backgrounds, skills, and experiences regardless of race, ethnicity, color, religion, sex, disability, nationality, or other differentiation, and our leaders leverage the differences within their teams. We also believe D&I is vital to our ability to grow and innovate in an ever-changing, fast-paced environment. Our diverse and inclusive workplace encourages different perspectives and ideas, which we believe enables better business decisions. The following are highlights of our D&I program:
Employee Resource Groups (“ERGs”) are a key component of our corporate culture and an important part of our diversity and inclusion strategy. We currently sponsor 15 ERGs, which are employee-led and open to all employees, including: African American Shipbuilders Association, Asian & Pacific Islander Shipbuilding Association, Generational Integration Focus Team, Hispanic Outreach & Leadership Alliance, Women in Shipbuilding Enterprise, Ingalls Shipbuilders Equality Alliance, Shipbuilders Together Realizing Inclusion, Diversity and Equality, and the Veterans Employee Resource Group.
We have established D&I Councils at our Corporate Office and at each of our three segments, which provide strategic direction, guidance, and advocacy for our D&I initiatives and advancements. These councils are led by senior executives and include high-performing employees and leaders from across our enterprise.
We have a long history of participation in a number of annual national diversity conferences, including Black Engineer of the Year Awards, Society of Hispanic Engineers and Professionals, Society of Asian Scientists and Engineers, Society of Women Engineers, Great Minds in STEM, Hispanic Engineers National Achievement Award Conference, Women of Color STEM Conference, and the National Society of Black Engineers Convention. These events provide recruitment, recognition, and development opportunities for our diverse workforce.

Employee Engagement - Since 2006, we have conducted an annual anonymous engagement survey of our workforce, both non-represented and represented. Administered and analyzed by an independent third party, the survey results are reviewed by our executive team and other senior leaders at our three segments. The results of this engagement survey are also shared with individual managers and employees, who are then tasked with discussing the results with their teams and working together to set goals and implement actions to improve employee engagement and performance. Approximately 72% of our workforce participated in the 2021 engagement survey. We believe that, at the individual employee level, engagement is about taking ownership of your work and work processes. At the enterprise level, engagement is about creating an inclusive and highly collaborative culture where we all care about and encourage each other’s success, and supporting the opportunity to create more value and transform our business for the future.

Item 1A. Risk Factors


An investment in our common stock or debt securities involves risks and uncertainties. We seek to identify, manage, and mitigate risks to our business, but risk and uncertainty cannot be eliminated or necessarily predicted. You should consider the following factors carefully, in addition to the other information contained in this Annual Report on Form 10-K, before deciding to purchase our securities.


Industry and Economic Risk Factors

We depend heavily on a single customer, the U.S. Government for substantially all of our business, and changes affecting this customer's priorities and spendingrisks that arise from conducting business with the U.S. Government could have a material adverse effect on our financial position, results of operations, or cash flows.


OurA substantial majority of our business consists primarily of the design, construction, repair, and maintenance of nuclear-powered ships such as aircraft carriers and submarines, and non-nuclear ships, such as surface combatants and expeditionary warfare and amphibious assault ships for the U.S. Navy and coastal defense surface ships for the U.S. Coast Guard, as well as the refueling and overhaul and inactivation of nuclear-powered ships for the U.S. Navy. We also provide fleet sustainment services to the U.S. Navy, IT and mission-based solutions for the DoD and intelligence and federal civilian customers, and nuclear management and operations and environmental management services for the DoE and DoD. Substantially all of our revenues in 20172021 were derived from products and services sold to the U.S. Government, and we expect this to continue in the foreseeable future. In addition, mostsubstantially all of our backlog as of December 31, 2017,2021, was U.S. Government related. Our U.S. Government contracts are subject to various risks, including our customers'customer political and budgetary constraints and processes, changes in customers' short-rangecustomer short-term and long-rangelong-term strategic plans, the timing of contract awards, significant changes in contract scheduling, intense contract award and funding competition, difficulty in forecasting costs and schedules for bids on developmental and sophisticated technical work, and contractor suspension or debarment in the event of certain violations of legal or regulatory requirements.violations. Any of these factors could affect our business with the U.S. Government, which would have a material adverse effect on our financial position, results of operations, or cash flows.


Significant delays or reductions in appropriations for our programs, changes in customer priorities, and potential contract terminations could have a material adverse effect on our financial position, results of operations, or cash flows.


We are directly dependent upon congressionalCongressional funding of U.S. Navy, and U.S. Coast Guard, programs. Theand other government agency programs. Under the normal legislative process, Congress completes 12 annual appropriation bills each fiscal year to fund the activities of federal agencies. When Congress is unable to pass these appropriation bills before the beginning of a fiscal year, a continuing resolution can be enacted to provide stopgap funding for a specified period of time at a specified rate, often the prior year’s appropriation level. When the U.S. Government operates under a continuing resolution, limitations can be placed on production increases, multi-year procurements, and new program starts, which may result in delays or cancellation of new contract awards. When the U.S. Government fails to enact annual appropriations or a continuing resolution, a full or partial federal government shutdown may occur. A federal government shutdown could, in turn, result in the delay or cancellation of key programs, is subject to congressional budget authorizationor the delay of contract payments, which could have a negative effect on our cash flows and appropriation processes. adversely affect our future results of operations.

For certain programs, Congress appropriates funds on aan annual fiscal year basis even though athe program performance period may be performedextend over several fiscal years. Consequently,Such programs are often partially funded initially on a partial basis, and receive additional fundingfunds are committed only as Congress makes additionalfurther appropriations. If we incur costs in excess of existing funding on a contract, we may be at risk for recovery ofnot recover those costs unless and until additional funds are appropriated. We cannot predict the extent to which total funding or funding for individual programs will be included, increased, or reduced as part of the annual budget process or through continuing resolutions or individual supplemental appropriations.


The impact of Congressional actions to reduce the federal debt and resulting pressures on federal spending could adversely affect the total funding of individual contracts or funding for individual programs and delay purchasing or payment decisions by our customers. In August 2011, the Budget Control Act (the "BCA") established limits on U.S. Government discretionary spending, including a reduction of defense spending by approximately $487 billion from fiscal years 2012 through 2021, representing approximately 8% of planned defense spending. The BCA also provided that the defense budget would face “sequestration” cuts of up to an additional $500 billion during that same period to the extent that discretionary spending limits are exceeded,representing approximately 9% of planned defense spending, and $500 billion for non-defense discretionary spending, including the U.S. Coast Guard.

The Bipartisan Budget Act of 2018 (the “BBA 2018”) provided sequestration relief for fiscal years 2018 and 2019.  Sequestration remains in effect, however, for fiscal years 2020 and 2021. Long-term uncertainty is continuingexists with respect to overall levels of defense spending across the future yearsyears' defense plan, and itplan. It is likely that U.S. Government discretionary spending levels, including defense spending, will continue to be subject to significant pressure. For additional information relating to the U.S. defense budget, see the Business Environment section ofunder Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7.

Demand for our products and services can also be affected by potential changesshifts in customer priorities due toresulting from changes in military strategy and planning. In response to the need for cheaperless expensive alternatives and the increasing proliferation of "smartadvanced weapons," future strategy reassessments by the DoD may result in decreased demand for our shipbuilding programs, including our aircraft carrier programs. For the year ended December 31, 2017,2021, our aircraft carrier

programs accounted for approximately 31%32% of our consolidated revenue. We cannot predict the impact of changes to customer priorities on existing, follow-on, replacement, or future programs. A shift of priorities to programs in which we do not participate and related reductions in funding for or the termination of programs in which we do participate could have a material adverse effect on our financial position, results of operations, or cash flows.
 
As of December 31, 2021, our total backlog was $48.5 billion, including $22.7 billion in funded backlog. The U.S. Government generally has the ability to terminate contracts, in whole or in part, with little or no prior notice, for convenience or for default based onupon performance. In the event of termination of a contract for the U.S. Government's convenience, a contractor is normally able to recover costs already incurred on the contract and receive profit on thoseincurred costs up to the amount authorized under the contract, but not the anticipated profit that would have been earned had the contract been completed. Such aOur unfunded backlog, in particular, contains management’s estimate of amounts expected to be realized on unfunded contracts that may never be realized as revenues. Any termination could also result in the cancellation of future work on the related program. TerminationA termination resulting from our default can expose us to various liabilities, including excess re-procurement costs, and could negatively affect our ability to compete for future contracts. Any contract termination could have a material adverse effect on our financial condition, results of operations, or cash flows.

Cost growth on flexibly priced contracts that cannot be justified as increases in contract value due from customers exposes us to reduced profitability and to the potential loss of future business.

Our operating income is adversely affected when we incur certain contract costs or certain increases in contract costs that cannot be billed to customers. Cost growth can occur if expenses to complete a contract increase due to technical challenges, manufacturing difficulties, delays, workforce-related issues, or inaccurate estimates used to calculate contract costs initially. Reasons may include unavailability or reduced productivity of labor, the nature and complexity of the work performed, the timeliness and availability of materials, major subcontractor performance or product quality issues, performance delays, availability and timing of funding from the customer, and natural disasters. The process of estimating contract costs requires significant judgment and expertise. A significant increase in contract costs from our original cost estimates on one or more contracts could have a material adverse effect on our financial position, results of operations, or cash flows.

Our ability to recover the costs we incur and realize profits on contracts with our U.S. government customers depends on the type of contract under which we are performing. Our U.S. Government business is currently performed under firm fixed price ("FFP"), fixed price incentive ("FPI"), cost plus incentive fee ("CPIF"), cost plus fixed fee ("CPFF"), and cost plus award fee ("CPAF") contracts. Under FFP contracts, we retain all cost savings on completed contracts but are responsible for the full amount of all expenditures in excess of the contract price. FPI contracts, on the other hand, are flexibly priced agreements under which cost overruns and underruns to an agreed target cost are shared between the U.S. Government and us. The U.S. Government is liable for its share of allowable costs up to a ceiling price, and we are responsible for all costs incurred in excess of such ceiling price, typically 125-135% of target cost. Our profit on FPI contracts varies according to a contract formula that generally compares the amount of costs incurred to the contract target cost. Under CPIF, CPFF, and CPAF contracts, we are generally required to perform the contract only to the extent the U.S. Government makes funds available, and we recover all allowable costs incurred in the performance of the contract. Under CPIF contracts, our profit is determined by a contractually specified formula that compares allowable incurred costs to the contract target cost, subject in some instances to a maximum or minimum fee percentage. Under CPFF contracts, the dollar amount of profit received is the same without regard to the amount of costs incurred. Under CPAF contracts, the dollar amount of profit received is determined by the award fee provisions in the contract.

Of Ingalls' revenues in 2017, approximately 89% were generated from FPI contracts, approximately 5% were generated from CPAF contracts, approximately 3% were generated from CPFF contracts, and approximately 3% were generated from FFP contracts. Of Newport News' 2017 revenues, approximately 50% were generated from CPFF contracts, approximately 41% were generated from FPI contracts, and approximately 9% were generated from CPIF contracts. Of Technical Solutions' revenues in 2017, approximately 33% were generated from time and material contracts, approximately 28% were generated from CPFF contracts, approximately 29% were generated from FFP contracts, approximately 7% were generated from CPAF contracts, approximately 1% were generated from FPI contracts, and approximately 2% were generated from CPIF contracts. To the extent our mix of contract types changes in the future, our ability to recover our costs and realize profits on our contracts could be negatively affected.


Our earnings and profitability depend upon our ability to perform our contracts.
When agreeing to contract terms, we make assumptions and projections about future conditions and events, many of which extend over long periods. Our assumptions and projections are based, among other matters, upon our assessments of the productivity and availability of labor, the complexity of the work to be performed, the cost and availability of materials, the impact of delayed performance, and the timing of product deliveries. We may experience significant variances from our assumptions and projections, delays in our contract performance, and variances in the timing of our product deliveries. If our actual experience differs significantly from our assumptions or projections or we incur unanticipated contract costs, the profitability of the related contracts may be adversely affected.

Our earnings and profitability depend, in part, upon subcontractor performance and raw material and component availability and pricing.
We rely on third parties to provide raw materials, major components and sub-systems, hardware elements, and sub-assemblies for our products and to perform certain services we provide to our customers, and to do so in compliance with applicable laws and regulations. Disruptions and performance problems caused by our suppliers and subcontractors, or a misalignment between our contractual obligations to our customers and our agreements with our subcontractors and suppliers, could have an adverse effect on our ability to meet our commitments to customers. Our ability to perform our obligations on a timely basis could be adversely affected if one or more of our suppliers or subcontractors are unable to provide the agreed-upon products or materials or perform the agreed-upon services in a timely, compliant and cost-effective manner or otherwise fail to satisfy contractual requirements. The inability of our suppliers or subcontractors to perform could also result in the need for us to transition to alternate parties, which could result in significant incremental cost and delay, or the need for us to provide other supplemental means to support our existing suppliers and subcontractors.
Our costs to manufacture our products can increase over the terms of our contracts, including as a result of increases in material costs. We may be protected from increases in material costs through cost escalation provisions in some of our contracts, to the extent that such increases are consistent with industry indices. Even with these provisions, however, the difference in basis between our actual material costs and these indices may expose us to cost uncertainty. In addition, significant delays in deliveries of key raw materials, which may occur as a result of availability or price, could have a material adverse effect on our financial position, results of operations, or cash flows.
In some cases, only one supplier may exist for certain components and parts required to manufacture our products. The inability of a sole source supplier to provide a necessary component or part in a timely, compliant, or cost-effective manner could increase our contract cost and affect our ability to perform our contract.

Our procurement practices are intended to provide quality materials and services to support our programs and to reduce the likelihood of our procurement of unauthorized, non-compliant, or deficient materials and services. We rely on our subcontractors and suppliers to comply with applicable laws, regulations, and the expectations set forth in the HII Supplier Code of Conduct regarding the materials and services we procure from them. In some circumstances, we rely on representations and certifications from our subcontractors and suppliers regarding their compliance. We also work with subcontractors and suppliers to conduct technical assessments, inspections, and audits, as necessary. Notwithstanding the actions we take to mitigate the risk of receiving materials and services that fail to meet specifications or requirements, subcontractors and suppliers have in the past provided us with unauthorized, non-compliant, or deficient materials and services.

Our inability to procure, or a significant delay in acquiring, necessary raw materials, components, or parts, the failure of our subcontractors or suppliers to comply with applicable laws and regulations, inaccurate certifications from our subcontractors and suppliers regarding their compliance, or noncompliant materials, components, or parts we acquire from our subcontractors and suppliers could have a material adverse effect on our financial position, results of operations, or cash flows.



Changes to Department of Defense business practices could have a material effect on DoD's procurement process and adversely impact our current programs and potential new awards.


The defenseOur industry has experienced, and we expect will continue to experience, significant changes to business practices resulting from an increasedgreater focus by DoD on affordability, efficiencies, business systems, recovery of costs, and a reprioritization of available defense funds to key areas for future defense spending. The DoD continuesThese initiatives and changes to adjust its procurement practices requirements criteria,may change the way U.S. Government contracts are solicited, negotiated, and source selection methodology in an ongoing effortmanaged, and may impact whether and how we pursue opportunities to reduce costs, gain efficiencies,provide our products and enhance program managementservices to the U.S. Government, including the terms and control. We expect DoD's focus on business practices to impact the contracting environment inconditions under which we operate as we and others in the industry adjust our practices to address the DoD's initiatives and the reduced level of spending by the DoD. Depending on how these initiatives are implemented, they coulddo so, which may have an adverse impact on our current programs, as well asbusiness, financial condition, results of operations, and cash flows. Changes in procurement practices favoring incentive-based fee arrangements, different award fee criteria, non-traditional contract provisions, and government contract negotiation offers that mandate our costs may affect our profitability and the predictability of our profit rates. The U.S. Government is also pursuing alternatives to shift additional responsibility and performance risks to contractors.

For example, the DoD is increasingly pursuing accelerated development and acquisition of new technologies through rapid acquisition pathways and procedures, including through other transaction authority agreements (“OTAs”). In recent years, the DoD has increased the frequency of use and size of OTAs, and we expect this trend to continue in the future. OTAs are exempt from many traditional procurement laws, including the FAR, and may be used, subject to certain conditions, for research, prototype development, and follow-on production for a successful prototype. The conditions for OTA awards include, in certain instances, that a significant portion of the work under the OTA be performed by a non-traditional defense contractor or that a portion of the cost of the protoype project be funded by non-governmental sources. If we cannot successfully adapt to the DoD’s accelerated acquisition processes or if the DoD significantly increases the use of OTAs with non-traditional defense contractors or increases cost sharing mandates, then we may lose new strategic business opportunities with the DoD. in high-growth areas and our future performance and results of operations could be adversely affected.

In addition to DOD'sthe DoD's business practice initiatives, the DCMA and DCAA have implemented cost recovery/cost savings initiatives to prioritize efforts to recover costs.cost recovery/savings. As a result of certain of these initiatives, we have experienced and may continue to experience a higher number of audits and/or lengthened periods of time required to close open audits. In addition,Moreover, the thresholds for certain allowable costs, including compensation costs, have been significantly reduced, and the allowability of other thresholdstypes of costs are being challenged, debated, and, in certain cases, modified. Significant changes to the thresholds for allowable costs or the allowability of certain costs could adversely affect our financial position, results of operations, or cash flows.

Our future success depends, in part, on our ability to deliver our products and services at an affordable life cycle cost, requiring us to develop and maintain technologies, facilities, equipment, and a qualified workforce to meet the needs of current and future customers.


Shipbuilding is a long cycle business, and our success depends on quality, cost, and schedule performance on our contracts. Our success depends upon our ability to develop and maintain the workforce, technologies, facilities, equipment, and financial capacity needed to deliver our products and services at an affordable life cycle cost. If we fail to maintain our competitive position in these areas, we could lose future contracts to our competitors, which could have a material adverse effect on our financial position, results of operations, or cash flows.

Our operating results are heavily dependent upon our ability to attract and retain at competitive costs a sufficient number of engineers and workers with the necessary skills and security clearances. At the same time, stable future revenues and costs are important for us to maintain a qualified workforce. Development and maintenance of the necessary nuclear expertise and the challenges of hiring and training a qualified workforce can be a limitation on our business. If qualified personnel become scarce, we could experience higher labor, recruiting, or training costs to attract and retain qualified employees, or, if we fail to attract and retain qualified personnel, we could incur difficulties performing our contracts and attracting new contract awards.

Competition within our markets or an increase in bid protests may reduce our revenues and market share.
 
U.S. defense spending levels are uncertain and difficult to predict. TheA longer term reduction in shipbuilding activity by the U.S. Navy, evidenced by the reduction in fleet size from 566 ships in 1989 to 280295 ships as of December 31, 2017,2021, has resulted in workforce reductions in the industry but littlelimited infrastructure consolidation. The general result has been fewer contracts awarded to the same fixed number of shipyards. SixFive major private United States shipyards, threetwo of which we own, plus many other smaller private shipyards compete for contracts to construct, overhaul, repair, and convert naval vessels. Additionally, our products, such as aircraft carriers, submarines, amphibious assault ships, surface combatants, and other ships, compete for funding with each other, as well as with other defense products and services. We expect competition for future shipbuilding programs to be intense.


We compete with another large defense contractor for construction contracts to build surface combatants, submarines, and large deck amphibious ships.ships, and smaller shipyards have entered the market for surface combatants. We may compete in the future compete with the same contractor and other defense contractorsshipyards to build othernew and different classes of ships, as well as ships for which we are currently the sole source, including expeditionary warfare and other amphibious assault ships. Moreover, reductions in U.S. defense spending that reduce the demand for the types of ships we build and services we provide increase our risk exposure to market competition. If we are unable to continue to compete successfully against our current or future competitors, we may experience lower revenues and market share, which could negatively impact our financial condition, results of operations, or cash flows.



Although we are the only company currently capable of refueling nuclear-powered aircraft carriers, two existing U.S. Government-owned shipyards may be able to refuel nuclear-powered aircraft carriers if substantial investments in facilities, personnel, and training were made. U.S. Government-owned shipyards currently engage in the refueling, overhaul, and inactivation of Los Angeles class (SSN 688) submarines and are capable of repairing and overhauling non-nuclear ships. If a U.S. Government-owned shipyard became capable and engaged in the refueling of nuclear-powered aircraft carriers, our financial position, results of operations, or cash flows could be adversely affected.
 
We also compete in the shipbuilding engineering, planning, and design market with other companies that provide engineering support services. Such competition increases the risk we may not be the successful bidder on future U.S. Navy engineering proposals, including aircraft carrier research and development, submarine design, and surface combatant and amphibious assault ship program contracts.
 
Our competitive environment is also affected by bid protests from unsuccessful bidders on new program awards. As the competitive environment intensifies, the number of bid protests may increase. Bid protests can result in an award decision being overturned, requiring a re-bid of the contract. Even when a bid protest does not result in a re-bid, resolution of the matter typically extends the time until contract performance can begin, which maycan reduce our earnings in the period in which the contract would otherwise be performed.


As a U.S. Government contractor, we are heavily regulated and could be adversely affected by changesChanges in regulations or negative findings from a U.S. Government audit or investigation.
As a U.S. Government contractor, we must comply with significant regulatory requirements, including those relating to procurement, cyber security, and nuclear operations. Government contracting requirements increase our contract performance and compliance costs and risks and change on a routine basis. In addition, our nuclear operations are subject to an enhanced regulatory environment, which results in increased performance and compliance efforts and costs. New laws, regulations, or procurement requirements, or changes to existing ones (including, for example, regulations related to recovery of compensation costs, cyber security, counterfeit parts, specialty metals, and conflict minerals), can increase our performance and compliance costs and risks and reduce our profitability.
We are routinely audited and reviewed by the U.S. Government and its various agencies, including the U.S. Navy's Supervisor of Shipbuilding, the DCAA, and the DCMA. These agencies review our contract performance, cost structures, and compliance with applicable laws, regulations, and standards, as well as the adequacy of our business systems and processes relative to U.S. Government requirements. If an audit uncovers improper or illegal activities, we may be subject to administrative, civil, or criminal proceedings, which could result in fines, penalties, repayments, or compensatory, treble, or other damages. Certain U.S. Government findings against a contractor can also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Allegations of impropriety can also cause us significant reputational harm.

Whether or not illegal activities are alleged, the U.S.Government has the ability to decrease or withhold contract payments if it determines significant deficiencies exist in business systems subject to its review. In the past the U.S. Government has, in certain instances, withheld contract payments upon its assessment that deficiencies existed with one or more of our business systems. When appropriate, we must modify our affected business systems to address the U.S. Government's determinations.
The U.S. Government has, from time to time, recommended that certain of our contract prices be reduced, or that certain costs allocated to our contracts be disallowed. These recommendations sometimes involve substantial dollar amounts. In response to U.S. Government audits, investigations, and inquiries, we have also in the past made adjustments to our contract prices and the costs allocated to our government contracts. Such audits, investigations, and inquiries may result in future reductions of our contract prices. Any costs we incur that are determined to be unallowable or improperly allocated to a specific contract will not be recovered or must be refunded if previously reimbursed.
We must comply with a variety of federal laws and regulations, including the FAR, the Truth in Negotiations Act, the False Claims Act, the Procurement Integrity Act, the International Traffic in Arms Regulations promulgated under the Arms Export Control Act, the Close the Contractor Fraud Loophole Act, the Foreign Corrupt Practices Act, and Cost Accounting Standards. If a determination is made that we engaged in illegal activities or did not act responsibly, as defined by the law, we may be subject to reductionsestimates used in contract values, contract modifications or terminations,

penalties, fines, repayments, compensatory, treble, or other damages, or suspension or debarment, any of which could have a material adverse effect on our financial position, results of operations, or cash flows.
Many of our contracts contain performance obligations that require innovative design capabilities or state-of-the-art manufacturing expertise, include technological complexity, or are dependent upon factors not wholly within our control, and failure to meet these obligations could adversely affect our profitability and future prospects.
We design, develop, and manufacture products and provide services applied by our customers in a variety of environments. Problems and delays in product development or with delivery of subcontractor components or services as a result of issues with respect to design, technology, licensing and intellectual property rights, labor, learning curve assumptions, or materials and parts could prevent us from satisfying contractual requirements.
First-in-class ships, also known as lead ships, usually include new technology that is supplied by the U.S. Navy, other contractors, or us. Problems developing these new technologies or design changes in the construction process can lead to delays in the design schedule for construction. The risks associated with new technology or mid-construction design changes can both increase the cost of a ship and delay delivery. Late delivery of information can also cause inefficiencies in the construction process, increase costs, and put the delivery schedule at risk, which could adversely affect our profitability and future prospects.
Our products cannot always be tested and proven and are otherwise subject to unforeseen problems, including premature failure of products that cannot be accessed for repair or replacement, substandard quality or workmanship, and unplanned degradation of product performance. These failures could result in loss of life or property and could negatively affect our results of operations by causing unanticipated expenses not covered by insurance or indemnification from the customer, diversion of management focus to respond to unforeseen problems, loss of follow-on work, and, in the case of certain contracts, repayment to the customer of contract costs and fee payments previously received.
We periodically experience quality issues with respect to products and services that we sell to our U.S. Government customers. These issues can and have required significant resources to analyze the source of the deficiencies and implement corrective actions. We may discover quality issues in the future related to our products and services that require analysis and corrective action. Such issues and our responses and corrective actions could have a material adverse effect on our financial position, results of operations, or cash flows.

We use estimates when accounting for contracts. Changes in estimates could affect our profitability and our overall financial position.
 
Contract accounting requires judgmentjudgments relative to assessing risks, estimating contract revenues and costs, and making assumptions regarding schedule and technical issues. The size and nature of many of our contracts make the estimation of total revenues and costs at completion complicated and subject to many variables. For new shipbuilding programs, we estimate, negotiate, and contract for construction of ships that are not completely designed, which subjects our risk assessments, revenue and cost estimates, and assumptions regarding schedule and technical issues to the variability of the final ship design and evolving scope of work. Our judgment, estimation, and assumption processes are significant to our contract accounting, and materially different amounts can be generatedresult if different assumptions are used or if actual events differ from our assumptions. Future changes in underlying assumptions, circumstances, or estimates may have a material adverse effect on our future financial position, results of operations, or cash flows. See Critical Accounting Policies, Estimates,the Contracts section under Management's Discussion and JudgmentsAnalysis of Financial Condition and Results of Operations in Item 7.

Our debt exposes us to certain risks.

As of December 31, 2021, we had $2.6 billion of debt under our senior notes, $625 million of term loan debt, $105 million of revenue bonds, $1.5 billion of additional borrowing capacity under our revolving credit facility (the "Revolving Credit Facility"), and $1 billion of borrowing capacity under our commercial paper program. Our
14


Revolving Credit Facility also allows us to solicit lenders to provide incremental financing capacity in an aggregate amount not to exceed $1 billion, and the indentures governing our senior notes do not limit our incurrence of debt.

Our ability to make payments on and to refinance our current or future indebtedness will depend on our ability to generate cash from operations, financings, or asset sales, which may be subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond our control. If we are not able to repay or refinance our debt as it becomes due, we may be forced to sell assets or take other unfavorable actions, including reducing financing for working capital, capital expenditures, and general corporate purposes; reducing our cash dividend rate and/or share repurchases; or dedicating an unsustainable level of our cash flow from operations to the payment of principal and interest on our indebtedness. In addition, our ability to withstand competitive pressures and to react to changes in the defense industry could be impaired. In the event of a default on any of our indebtedness, the lenders who hold such debt could accelerate amounts due, which could potentially trigger a default or acceleration of any of our other debt.

The interest rates on variable rate indebtedness under our Revolving Credit Facility and Term Loan are based upon the London Interbank Offered Rate (“LIBOR”). LIBOR has been the subject of national, international, and other regulatory guidance and proposals for reform. In March 2021, LIBOR’s regulator, the U.K. Financial Conduct Authority, announced that the publication of rates for one-week and two-month U.S. Dollar LIBOR maturities and all non-U.S. LIBOR maturities would cease immediately after December 31, 2021, with all other tenors ceasing immediately after June 30, 2023. In the U.S., the Alternative Reference Rate Committee has identified the Secured Overnight Financing Rate (“SOFR”) as its preferred alternative upon termination of LIBOR, although other alternatives, including Bloomberg’s Short-Term Bank Yield, are available. We cannot predict the consequences of the benchmark transition from LIBOR to SOFR or another benchmark, but the transition may potentially increase the cost of our variable rate indebtedness.

Business and Operational Risk Factors

Cost growth on flexibly priced contracts that does not result in higher contract value due from customers reduces our profit and exposes us to the potential loss of future business.

Our operating income is adversely affected when we incur certain contract costs or certain increases in contract costs that cannot be billed to customers. Cost growth can occur if expenses to complete a contract increase due to technical challenges, manufacturing difficulties, delays, workforce-related issues, or inaccurate initial contract cost estimates. Reasons may include labor unavailability or reduced productivity, the nature and complexity of the work performed, the timeliness and availability of materials, major subcontractor performance or product quality issues, performance delays, availability and timing of funding from the customer, and natural disasters. The process of estimating contract costs requires significant judgment and expertise. A significant increase in contract costs from our original cost estimates on one or more contracts could have a material adverse effect on our financial position, results of operations, or cash flows.

Our ability to recover costs and realize profits on contracts with our U.S. Government customers depends upon the type of contract under which we are performing. Our U.S. Government business is currently performed under firm fixed-price, fixed-price incentive, cost-type, and time and material contracts. Under firm fixed-price contracts, we agree to perform the specified work for a pre-determined price. To the extent our actual costs vary from the estimates upon which the price was negotiated, we will generate more or less profit or could incur a loss. Some firm fixed-price contracts have a performance-based component under which we may earn incentive payments or incur financial penalties based upon our performance. Fixed-price incentive contracts provide for reimbursement of the contractor’s allowable costs incurred in performance of the contract, subject to a cost-share limit that impacts the profit on the contract. Cost-type contracts provide for the payment of allowable costs incurred during performance of the contract plus a fee up to a ceiling based on the amount that has been funded. Under time and material contracts, we are paid for direct labor hours incurred at specified hourly rates plus material costs. See the Contracts section under Management's Discussion and Analysis of Financial Condition and Results of Operations in Item 7 for descriptions of the types of contracts that comprise our business.

Approximately 55% of our revenues in 2021 were generated under fixed-price incentive contracts, approximately 39% were generated under cost-type contracts, approximately 3% were generated under time and material contracts, and approximately 3% were generated under firm fixed-price contracts. Our failure to perform to customer expectations and contract requirements may result in reduced fees or losses and affect our financial performance.
15


Under each type of contract, if we are unable to control costs, our operating results could be adversely affected, particularly if we are unable to negotiate an increase in contract value to our customers. From time to time, we may begin performance under an undefinitized contract action with a not-to-exceed price prior to completing contract negotiations in order to support U.S. government priorities. Uncertainties in final contract price, specifications and terms, or loss of negotiating leverage associated with particularly long delays in contract definitization may negatively affect our profitability. Cost overruns or the failure to perform on existing programs also may adversely affect our ability to retain existing programs and win future contract awards. To the extent our mix of contract types changes in the future, our ability to recover our costs and realize profits on our contracts could be negatively affected.

Our earnings and profitability depend upon our ability to perform our contracts.
 
When agreeing to contract terms, we make assumptions and projections about future conditions and events, many of which extend over long periods. Our assumptions and projections are based upon our assessments of the productivity and availability of labor, the complexity of the work to be performed, the cost and availability of materials, the impact of delayed performance, the timing of product deliveries, and other matters. We may experience significant variances from our assumptions and projections, contract performance schedule delays, and variances in the timing of our product deliveries. If our actual experience differs significantly from our assumptions or projections or we incur unanticipated contract costs, the profitability of the related contracts may be adversely affected.

Our earnings and profitability depend, in part, upon subcontractor performance and raw material and component availability and pricing.
We rely on third parties to provide raw materials, major components and sub-systems, hardware elements, and sub-assemblies for our products and perform certain services we provide to our customers, and to do so in compliance with applicable laws and regulations, including various DoD cybersecurity requirements. Disruptions and performance problems caused by our suppliers and subcontractors, or misalignments between our contractual obligations to our customers and our agreements with our subcontractors and suppliers, could have an adverse effect on our ability to meet our commitments to customers. Our ability to satisfy our obligations on a timely basis could be adversely affected if one or more of our suppliers or subcontractors are unable to provide agreed-upon products or materials or perform agreed-upon services in a timely, compliant, and cost-effective manner or they otherwise fail to satisfy contractual requirements. The inability of our suppliers or subcontractors to meet expectations could also result in the need for us to transition to alternate parties, which could result in significant incremental cost and delay, or the need for us to provide other supplemental support to our existing suppliers and subcontractors.
Our costs to manufacture our products can increase over the terms of our contracts, including as a result of increases in material costs. Although we may be protected from increases in material costs through cost escalation provisions, the difference in basis between our actual material costs and industry indices may expose us to cost recovery risk. Significant increases in inflation, particularly those related to wages and increases in the cost of raw materials, may increase our cost recovery risk. In addition, significant delays in deliveries of key raw materials, which may occur as a result of availability or pricing, could have a material adverse effect on our financial position, results of operations, or cash flows.
In some cases, only one supplier may exist for certain components and parts required to manufacture our products. The inability of a sole source supplier to provide a necessary component or part on a timely, compliant, and cost-effective basis could increase our contract cost and affect our ability to perform our contract.

Our procurement practices are intended to provide quality materials and services to support our programs and to reduce the likelihood of our procurement of unauthorized, non-compliant, or deficient materials and services. We rely on our subcontractors and suppliers to comply with applicable laws, regulations, and the expectations set forth in the HII Supplier Code of Conduct. In some circumstances, we rely on representations and certifications from our subcontractors and suppliers regarding their compliance. We also conduct technical assessments, inspections, and audits, as necessary, with subcontractors and suppliers. Notwithstanding the actions we take to mitigate the risk of receiving materials and services that fail to meet specifications or requirements, subcontractors and suppliers sometimes provide us with unauthorized, non-compliant, or deficient materials and services.

Our inability to procure, or a significant delay in acquiring, necessary raw materials, components, or parts, the failure of our subcontractors or suppliers to comply with applicable laws and regulations, or noncompliant materials, components, or parts from our subcontractors and suppliers could have a material adverse effect on our financial position, results of operations, or cash flows.

Our future success depends, in part, on our ability to deliver our products and services at an affordable life cycle cost, requiring us to develop and maintain technologies, facilities, equipment, and a qualified workforce to meet the needs of current and future customers.

Shipbuilding is a long cycle business, and our success depends on quality, cost, and schedule performance on our contracts. In turn, our performance depends upon our ability to develop and maintain the workforce, technologies, facilities, equipment, and financial capacity to deliver our products and services at an affordable life cycle cost. If we fail to maintain our competitive position in these areas, we could lose future contracts to our competitors, which could have a material adverse effect on our financial position, results of operations, or cash flows.

Our operating results are heavily dependent upon our ability to attract and retain at competitive costs a sufficient number of engineers and other employees with the necessary skills and security clearances. At the same time, future revenues and costs impact our ability to maintain a qualified workforce. Development and maintenance of the necessary nuclear related and other specialized skills and the challenges of hiring and training a qualified workforce can be a limitation on our business. Shortages of qualified personnel can increase our recruiting, training, and overall labor costs, and a failure to attract and retain qualified personnel can impact our contract performance and ability to compete for new contracts.

Many of our contracts include performance obligations that incorporate innovative designs and state-of-the-art manufacturing expertise, include new technologies, or are dependent upon factors not wholly within our control, and failure to meet performance expectations could adversely affect our profitability and future prospects.
We design, develop, and manufacture products and provide services that often involve innovative designs, new technologies, and complex manufacturing processes. Problems and delays with product development, technology implementation, manufacturing, or subcontractor components or services as a result of issues with design, technology, licensing and intellectual property rights, labor, learning curve assumptions, or materials and parts could prevent us from satisfying contractual requirements.
First-in-class ships, also known as lead ships, usually include new technologies supplied by the U.S. Navy or other contractors or developed by us. Problems developing or implementing these new technologies or design changes in the construction process can lead to delays in the design and construction schedule. The risks associated with new technologies or design changes during construction can both increase the cost of a ship and delay delivery. Delays in receipt of necessary customer information can also cause inefficiencies in the construction process, increase costs, and put the delivery schedule at risk, which can adversely affect our profitability and future prospects.
Our products cannot always be tested and proven and are otherwise subject to unforeseen problems, including premature failure of elements that cannot be accessed for repair or replacement, substandard quality or workmanship, and unexpected degradation of product performance. These failures could result in loss of life or property and could negatively affect our results of operations by causing unanticipated expenses not covered by insurance or customer indemnification, diversion of management attention, loss of follow-on work, and, in the case of certain contracts, reimbursement to the customer of contract costs and fee payments previously received.
We periodically experience quality issues with respect to products and services that we sell to our U.S. Government customers. These issues can and have required significant resources to determine the source of the deficiencies and implement corrective actions. We may discover quality issues in the future related to our products and services that require analysis and corrective action. Such issues and our responses and corrective actions could have a material adverse effect on our financial position, results of operations, or cash flows.

17


Changes in key estimates and assumptions associated with postretirement benefit plans, such as discount rates and assumed long-term returns on assets, actual investment returns on our pension plan assets, and legislative and regulatory actions could significantly affect our financial position, results of operations, and cash flows.

Our pension and retiree health care costs are dependent upon various estimates and assumptions, particularly with respect to the discount rate and expected long-term rates of return on plan assets, which to a large extent are reflective of the financial markets and economic conditions. Changes to these estimates and assumptions and differences between expected and actual returns on plan assets could significantly impact our retirement related expense, the funded status of benefit plans, and contributions to our defined benefit pension and other postretirement benefit plans, which could have material adverse effects on our financial position, results of operations, or cash flows.

Additionally, pension cost recoveries under CAS for our U.S. Government contracts occur in different periods from those in which pension expense is recognized under accounting principles generally accepted in the United States ("GAAP") or the periods in which we make contributions to our benefit plans, and changes to estimates and assumptions and differences between expected and actual returns could adversely affect the timing of those pension cost recoveries.

Our business is subject to disruption caused by natural disasters, environmental disasters, and other events that could have a material adverse effect on our financial position, results of operations, or cash flows.
 
We have significant operations located in regions of the United States that have been and may in the future be exposed to damaging storms, such as hurricanes and floods, the intensity and frequency of which are being exacerbated by climate change, other impacts of climate change, including rising sea waters, and environmental disasters, such as oil spills. Natural disasters can disrupt our workforce, electrical and other power distribution networks, computer and internet operations and accessibility, and the critical industrial infrastructure needed for normal business operations, which couldcan adversely affect our contract performance and, as a result, our financial results. Environmental disasters, particularly oil spills in waterways and bodies of water usedwe use for the transporttransporting and testing of our ships, can disrupt the timing of performancecause schedule delays under our contracts with the U.S. Navy and the U.S. Coast Guard.


Damage and disruption resulting from natural and environmental disasters may be significant. Should insurance or other risk transfer mechanisms be unavailable or insufficient to recover material costs associated with natural or environmental disasters or other events, we could experience a material adverse effect on our financial position, results of operations, or cash flows. SeeOur insurance coverage may be inadequate to cover all of our significant risks or our insurers may deny coverage of material losses we incur, which could adversely affect our profitability and financial position.
 
Our suppliers and subcontractors are also subject to natural and environmental disasters that could affect their ability to deliver products or services or otherwise perform their contracts. Performance failures by our subcontractors due to natural or environmental disasters may adversely affect our ability to perform our contracts, which could reduce our profitability in the event damages or other costs are not recoverable from the subcontractor, the customer, or insurers. Such events could also result in a termination of the prime contract and have an adverse effect on our ability to compete for future contracts.


In additionWe face risks related to health epidemics, pandemics, and similar outbreaks, and our business has been and will continue to be adversely affected by the typesCOVID-19 pandemic.

We face various risks related to health epidemics, pandemics and similar outbreaks, including the global outbreak of events described above, operationCOVID-19. Such risks include disruptions or restrictions on our employees’ ability to work or work effectively, temporary closures of our facilities may be disrupted by civil unrest, acts of sabotage or terrorism, and other local security concerns. Such events may require us to incur greater costs for security or to shut down operations for a period of time.
Our insurance coverage may be inadequate to cover allthe facilities of our significant riskscustomers or suppliers, and delays in supplier deliveries. We have experienced higher employee absentee rates as a result of COVID-19, which has impacted our insurersoperations and financial results. Higher absentee rates attributable to COVID-19, including because of illness, quarantines, government actions, facility closures, or other restrictions resulting from COVID-19, have impacted and may deny coverage of material losses we incur,continue to impact performance on our contracts and have increased and may continue to increase our costs. These impacts may continue, and the cost increases may not be fully recoverable under our contracts or adequately covered by insurance, which could adversely affectimpact our profitabilityprofitability.

COVID-19 has also caused disruption in our supply chain, caused delays in, and financial position.
We seek to negotiate and enter into insurance agreements to cover our significant risks and potential liabilities, including, among others, property loss from natural disasters, product liability, and business interruption resulting from an insured property loss. In some circumstances, we may be indemnified for losses bylimited the ability of, the U.S. Government and other customers to perform, which have included delays in contract award decisions, and caused other unpredictable events. Some or all of these impacts might continue into the future.

In September 2021, President Biden issued an executive order requiring certain employers with U.S. Government contracts to ensure that their U.S.-based employees, contractors, and subcontractors that work on or in support of U.S. Government contracts are fully vaccinated in accordance with the guidelines of the Safer Federal Workforce Task Force. In November 2021, OSHA issued an Emergency Temporary Standard (“ETS”) requiring that all employers with 100 or more employees mandate vaccines for covered employees or, in the alternative, weekly testing and masks. The U.S. federal contractor mandate was preliminarily enjoined by several U.S. federal district courts, the U.S. Supreme Court preliminarily stayed the OSHA ETS in January 2022, and OSHA subsequently withdrew the ETS.

While we are not currently subject to any vaccine mandate, it continues to be our policy to encourage each of our employees to be fully vaccinated against COVID-19. To the availability of appropriated funds. Not every risk or liability can be protected by insurance, and, for insurable risks, the limits of coverage reasonably obtainableextent we become subject to a vaccine mandate in the market may notfuture, our implementation of the mandate could result in employee attrition, including attrition of critical skilled labor, and difficulty meeting future labor requirements. If attrition is significant, our operations and ability to execute our contracts could be sufficientmaterially impacted. In addition, our subcontractors and suppliers who become subject to covera vaccine mandate could be impacted by an inability to comply or loss of personnel, which could disrupt subcontractor or supplier performance or deliveries, and negatively impact our business.

COVID-19 has already impacted our business and results of operations, and the ultimate impact of COVID-19 on our operations and financial performance in future periods, including our ability to execute our programs on the expected schedule, remains uncertain and will depend on future COVID-19 related developments, including the duration of the pandemic, potential subsequent waves of COVID-19 infection or potential new variants, the effectiveness of COVID-19 vaccines and the impacts of implementation of vaccine mandates, and related government actions to prevent and manage disease spread, all of which continue to be uncertain and cannot be predicted. As a result, we cannot predict the full amount of actual losses or liabilities incurred, including, for example, in the case of a catastrophic hurricane. In addition, the nature of our business makes it difficult to quantify the disruptive impact of such events. Limitations on the availability of insurance coverage may result in us bearing substantial costs for uninsured losses, whichCOVID-19, but it could have a material adverse effect onmaterially affect our business, financial position, results of operations, and/or cash flows. Even in cases where we have insurance coverage, disputes with insurance carriers over coverage may affect the timing of cash flows and, in the event of litigation with an insurance carrier, an outcome unfavorable to us may have a material adverse effect on our financial position, results of operations, or cash flows.future.

Our business could suffer if we are unsuccessful in negotiating new collective bargaining agreements.
 
Approximately 50%45% of our employees are covered by a total of nine9 collective bargaining agreements and two DoE1 site stabilization agreements.agreement. Newport News has four2 collective bargaining agreements covering represented employees, which expire in December 2022 and April 2024, and one ofthat expired in November 2021, which covers approximately 50% of Newport News employees and was renewed in July 2017. The remaining collective bargaining agreements at Newport News expire in August 2018, December 2018, and November 2020.employees. Newport News craft workers employed at the Kesselring Site near Saratoga Springs, New York are represented under an indefinite DoE site agreement. Ingalls has five collective bargaining agreements covering represented employees, all of which expire in March 2022.2026. Approximately 3515 Technical Solutions craft employees atin Klamath Falls, Oregon are covered by a collective bargaining agreement that expires in June 2025.

We reached a tentative agreement with representatives of United Steelworkers (“USW”) Local 8888 (Newport News) members on a new labor agreement in November 2021, but the Hanford Sitemembers of the bargaining unit declined to ratify the contract. The Newport News and USW negotiation teams continued negotiations and reached a tentative agreement on another labor agreement in January 2022. We expect the members of the bargaining unit to vote on the new agreement in the near Richland, Washingtonfuture. The USW Local 8888 members are representedcontinuing to work under an indefinite DoE site stabilization agreement.the terms and conditions of the expired collective bargaining agreement, but the members may call for a strike, or we may declare a lock-out, upon 48 hours notice. We cannot give any assurances that the tentative labor agreement will be ratified by the local bargaining unit or that a strike or lock-out will not occur.


Collective bargaining agreements generally expire after three to five years and we negotiate successor agreements as each of our collective bargaining agreements expires.are subject to renegotiation at that time. While we believe we maintain good relationships with our represented workers, it is possible we may experience difficulties renegotiating expiring collective bargaining agreements. We have experienced in the past experienced work stoppages, strikes, and other labor disruptions associated with the collective bargaining of new labor agreements. If we experience such events in the future, we could incur additional expenses or work delays that could adversely affect programs served by employees who are covered by collective bargaining agreements.

We could be negatively impacted by security threats, including cyber security threats, and related disruptions.
As a defense contractor, we rely on our information technology infrastructure to process, transmit, and store electronic information, including classified and other sensitive information of the U.S. Government. While we maintain stringent information security policies and protocols and implement security controls and complementary cyber security technologies in compliance with industry requirements, we face substantial cyber security threats to our information technology infrastructure, including threats to our and the U.S. Government's proprietary and classified information from advanced nation state threat actors, sophisticated cybercrime syndicates, hacktivists, and insiders. While we implement countermeasures to address the risks posed by these threats, external and internal threat actors continuously seek to evade our cyber security countermeasures to gain unauthorized and unlawful access to our information technology infrastructure, assets, and data.

Our information technology infrastructure is critical to the efficient operation of our business and essential to our ability to perform day-to-day operations. Breaches of our information technology or physical facilities could cause us to incur significant recovery and restoration expenses, degrade performance on existing contracts, and expose us to reputational damage, potential liability, or the loss of current or future contracts, including work on sensitive or classified systems for the U.S. Government, any of which could have a material adverse effect on our operations, financial position, results of operations, or cash flows.

Our suppliers, subcontractors, and other business partners also face cyber security and other security threats. Although we undertake cooperative efforts with our customers, suppliers, subcontractors, and other business partners to facilitate their understanding of cyber security threats they face and potential cyber security countermeasures to mitigate potential cyber-attacks, other security threats, and business disruptions, we rely substantially on the safeguards implemented by these organizations, which may affect the security of our information. These organizations have varying levels of cyber security expertise and safeguards, and their relationships with U.S. Government contractors may increase the likelihood that they are targeted by the same cyber security threats we face.

In addition to cyber threats, operation of our facilities may be disrupted by civil unrest, acts of sabotage or terrorism, and other local security issues. Such events may require us to incur greater costs for security or to shut down operations for a period of time.

Changes in keyfuture business conditions could cause business investments, recorded goodwill, and/or purchased intangible assets to become impaired, resulting in losses and write-downs that would reduce our operating income.
As part of our business strategy, we acquire non-controlling and controlling interests in businesses. We make acquisitions and investments following careful analysis and due diligence to achieve a desired return or strategic objective. Business acquisitions involve estimates, assumptions, and assumptions,judgments to arrive at acquisition prices, which are allocated among acquired assets, including goodwill, based upon fair market values. Notwithstanding our acquisition and business integration efforts, actual operating results of acquired businesses may vary significantly from expectations. In such events, we may be required to write down our carrying value of the related goodwill and/or purchased intangible assets. In addition, declines in the trading price of our common stock or the market as discount ratesa whole can result in goodwill and/or purchased intangible asset impairment charges associated with our existing businesses.

As of December 31, 2021, goodwill and assumed long-term returnspurchased intangible assets from prior business acquisitions accounted for approximately 25% and 11%, respectively, of our total assets. We evaluate goodwill values for impairment annually, or when evidence of potential impairment exists. We also evaluate the values of purchased intangible assets when evidence of potential impairment exists. The impairment tests are based on assets, actual investment returns on our pension plan assets,several factors requiring judgments. As a general matter, a significant decrease in expected cash flows or unfavorable changes in market conditions may indicate potential impairment of recorded goodwill or purchased intangible assets.

Legal and legislativeRegulatory Risk Factors

As a U.S. Government contractor, we are heavily regulated and could be adversely affected by changes in regulations or negative findings from a U.S. Government audit or investigation.
As a U.S. Government contractor, we must comply with significant regulatory requirements, including those relating to award, administration, and performance of U.S. Government contracts, as well as legal and regulatory actionsrequirements relating to cyber security, environmental protection and our nuclear operations. Government contracting requirements increase our contract performance costs and compliance costs and risks, and change on a routine basis. In addition, our nuclear operations are subject to an enhanced regulatory environment, which results in further performance and compliance requirements and higher costs. New laws, regulations, or procurement requirements, or changes to existing ones (including, for example, regulations related to recovery of compensation costs, cyber security, counterfeit parts, specialty metals, and conflict minerals), can increase our performance costs and compliance costs and risks, and reduce our profitability.
We are overseen and audited by the U.S. Government and its various agencies, including the U.S. Navy's Supervisor of Shipbuilding, the DCAA, and the DCMA. These agencies evaluate our contract performance, cost structures, and compliance with applicable laws, regulations, and standards, as well as the adequacy of our business systems and processes relative to U.S. Government requirements. If an audit uncovers improper or illegal activities, we may be subject to administrative, civil, or criminal proceedings, which could significantly affectresult in fines, penalties, repayments, or compensatory, treble, or other damages. Certain U.S. Government findings against a contractor can also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Allegations of impropriety can also cause significant reputational damage.

The U.S.Government also has the ability to decrease or withhold contract payments if it determines significant deficiencies exist in one or more of our earnings, financial condition,business systems. The U.S. Government has, in certain instances, withheld contract payments upon its assessment that deficiencies exist with one or more of our business systems, which can have a material impact on the timing of our cash receipts. For example, in January 2022, the Navy Contracting Officer issued a written determination that the Ingalls Shipbuilding Material Management and contributionsAccounting System has three significant deficiencies, resulting in a 5% withhold of payments on certain invoices issued under one contract. Ingalls Shipbuilding will submit a corrective action plan, and the withhold will be reduced to 2% if the Contracting Officer determines the corrective action plan has been implemented and is effective. The withhold will terminate and withheld funds returned to the Company when the Contracting Officer determines that the significant deficiencies have been corrected.

The U.S. Government has, from time to time, recommended that certain of our contract prices be reduced, or that certain costs allocated to our defined benefit pensioncontracts be disallowed, which sometimes involve substantial dollar amounts. In response to U.S. Government audits, investigations, and other postretirement benefit plansinquiries, we have also in the past made adjustments to our contract prices and costs allocated to our government contracts. Such audits, investigations, and inquiries may result in future periods.reductions of our contract prices. Costs we incur that are determined to be unallowable or improperly allocated to a specific contract will not be recovered or must be refunded if previously reimbursed.
 
Our pensionWe must comply with a variety of federal laws and retiree health care costsregulations, including the FAR, the DFARS, the Truth in Negotiations Act, the False Claims Act, the Procurement Integrity Act, the International Traffic in Arms Regulations promulgated under the Arms Export Control Act, the Close the Contractor Fraud Loophole Act, the Foreign Corrupt Practices Act, and CAS. If a determination is made that we engaged in illegal activities or that we are dependent upon significant judgment regarding various estimates and assumptions, particularly with respectnot presently responsible, as defined under the FAR, we may be subject to the discount rate and expected long-term ratesreductions in contract values, contract modifications or terminations, penalties, fines, repayments, compensatory, treble, or other damages, or suspension or debarment, any of return on plan assets. Changes to these estimates and assumptionswhich could have a material adverse effect on our financial position, results of operations, or cash flows. Differences between actual investment returnsIn addition, cyber security and data privacy and protection laws and regulations are evolving and present increasing compliance challenges, which increase our assumed long-term returns on assets will result in future changes in pension expensecosts and the funded status ofmay affect our plans,competitiveness, cause reputational harm, and could increase future funding of the plans.expose us to damages claims, substantial fines, or other penalties.


Unforeseen environmental

Environmental costs could have a material adverse effect on our financial position, results of operations, or cash flows.
 
Our operations are subject to and affected by a variety of existing federal, state, and local environmental protection laws and regulations.regulations relating to the discharge, storage, treatment, handling, disposal, and remediation of certain materials, substances, and wastes used in our operations. In addition, we could be affected by future environmental laws or regulations, including those imposed in response to concerns overregulations. Increased public awareness and concern regarding global climate change other aspectsmay result in more federal, regional, and/or international requirements to reduce or mitigate global warming, and legislation, international protocols or treaties, or regulation could mandate stricter limits on greenhouse gas emissions. Environmental laws and regulations may require the installation of costly pollution control equipment or operational changes to limit emissions or discharges and/or to decrease the environment, or natural resources.likelihood of accidental hazardous material releases. We expect to incur future capital and operating costs to comply with current and future environmental laws and regulations for environmental protection and remediation, and such costs could be substantial, depending on the future proliferation of environmental rules and regulationsrequirements and the extent to which we discover currently unknown environmental conditions.
 
Shipbuilding operations require the use of hazardous materials. Our shipyards also generate significant quantities of wastewater, which we treat before discharging pursuant to variousin accordance with applicable permits. To handlemanage these materials, our shipyards have an extensive network of abovegroundabove ground and underground storage tanks, some of which have leaked and required remediation in the past. In addition, our handling of hazardous materials has sometimes resulted in spills in our shipyards and occasionally in adjacent rivers and waterways in which we operate. Our shipyards maintain extensive waste handling programs that we periodically modify, consistent with changes in applicable laws and regulations. See Environmental, Health and Safety in Item 1.
 
Various federal, state, and local environmental laws and regulations impose restrictions on the discharge of pollutants into the environment and establish standards for the transportation, storage, and disposal of toxic and hazardous wastes. Substantial fines, penalties, and criminal sanctions may be imposed for noncompliance, and certain environmental laws impose joint and several "strict liability" for remediation of spills and releases of oil and hazardous substances. Such laws and regulations renderimpose liability upon a party liable for environmental cleanup and remediation costs and damage without regard to the negligence or fault on the part of such party and could expose us to liability for the conduct of or conditions caused by third parties.
In addition to fines, penalties, and criminal sanctions, environmental laws and regulations may require the installation of costly pollution control equipment or operational changes to limit pollution emissions or discharges and/or to decrease the likelihood of accidental hazardous material releases. We expect to continue to incur costs to comply with federal and state environmental laws and regulations related to the cleanup of pollutants released into the environment. In addition, Moreover, if we are found to be in violation ofviolate the Clean Air Act or the Clean Water Act, the facility or facilities involved in the violation could be placed by the EPA on the "Excluded Parties List" maintained by the General Services Administration, which would continue until the EPA concluded that the cause of the violation was cured. Facilities on the "Excluded Parties List" are prohibited from working on any U.S. Government contract.
 
The adoption of new environmental or climate change laws and regulations, stricter enforcement of existing laws and regulations, imposition of new cleanup requirements, discovery of previously unknown or more extensive contamination, litigation involving environmental impacts,matters, our inability to recover related costs under our government contracts, or the financial insolvency of other responsible parties could cause us to incur costs that could have a material adverse effect on our financial position, results of operations, or cash flows.

We ceased shipbuilding construction at our Avondale, Louisiana shipyard in 2014. Our wind down of operations at this shipyard may result in environmental costs, the amount of which we cannot currently estimate. Such costs could be significant and could have a material adverse effect on our financial position, results of operations, or cash flows.

Market volatility and adverse capital market conditions may affect our ability to access cost-effective sources of funding and may expose us to risks associated with the financial viability of suppliers and subcontractors.

The financial markets can experience high levels of volatility and disruption, reducing the availability of credit for certain issuers. We may access these markets from time to time to support certain business activities, including funding acquisitions and capital expansion projects and refinancing existing indebtedness. We also access these markets to obtain credit support for our workers' compensation self-insurance program and arrange for letters of credit. A number of factors could cause us to incur higher borrowing costs and to have greater difficulty accessing public and private markets for debt. These factors include disruptions or declines in the global capital markets and/or a decline in our financial performance, outlook, or credit ratings. The occurrence of any or all of these events may adversely affect our ability to fund our operations, meet contractual commitments, make future investments or desirable acquisitions, or respond to competitive challenges.
Tightening capital markets could also adversely affect our suppliers' and subcontractors' ability to obtain financing. Delays in suppliers' or subcontractors' ability to obtain financing, or the unavailability of financing, could negatively affect their ability to perform their contracts with us and cause our inability to perform our contracts. The inability of our suppliers and subcontractors to obtain financing could also result in the need for us to transition to alternate suppliers and subcontractors, which could result in significant incremental costs and delays.

Our reputation and our ability to doconduct business may be impacted by the improper conduct of employees, agents, or business partners.
 
Our compliance program includes detailed compliance plans and related compliance controls, policies, procedures, and training designed to prevent and detect misconduct by employees, agents, business partners, and others working on our behalf, including suppliers and subcontractors, that would violate the laws of the jurisdictions in which we operate, including laws governing payments to government officials, the protection of export controlled or classified information, cost accounting and billing, competition, and data privacy. Our business hasWe have been impacted in the past by the improper misconduct of employees and business partners, and we may not prevent all such misconduct in the future by our employees, agents, business partners, and others working on our behalf, including suppliers and subcontractors. Moreover, the risk of improper conduct may be expected to increase as we expand our operations into commercial markets and foreign jurisdictions. Any improper actions by our employees, agents, business partners, and others working on our behalf, including suppliers and subcontractors, could subject us to administrative, civil, or criminal investigations and monetary and non-monetary penalties, including suspension or debarment, which could have a material adverse effect on our financial position, results of operations, or cash flows. Any such improper actions could also cause us significant reputational damage.


Our business could be negatively impacted by security threats, including cyber security threats, and related disruptions.
22


As a defense contractor, we rely on our information technology infrastructure to process, transmit, and store electronic information, including classified and other sensitive information of the U.S. Government. While we maintain stringent information security policies and protocols, we face cyber security and other security threats to our information technology infrastructure, including threats to our and the U.S. Government's proprietary and classified information. We face unauthorized and unlawful attempts to gain access to our information technology infrastructure, including coordinated attacks from groups of hackers, and we could also face attempts to gain physical access to classified and other sensitive information located at our facilities. Our information technology infrastructure is critical to the efficient operation of our business and essential to our ability to perform day-to-day operations. Breaches of our information technology infrastructure or physical facilities could cause us to incur significant recovery and restoration expenses; degrade performance on existing contracts; and expose us to reputational damage, potential liability, or the loss of current or future contracts, including work on sensitive or classified systems for the U.S. Government, which could have a material adverse effect on our operations, financial position, results of operations, or cash flows.

In addition, our suppliers, subcontractors, and other business partners face cyber security and other security threats. Although we work cooperatively with our customers, suppliers, subcontractors, and other business partners to seek to minimize the impact of cyber threats, other security threats, and business disruptions, we must rely on the safeguards put in place by these entities, which may affect the security of our information. These entities have

varying levels of cyber security expertise and safeguards, and their relationships with U.S. Government contractors may increase the likelihood that they are targeted by the same cyber security threats we face.

Our nuclear operations subject us to various environmental, regulatory, financial, and other risks.
 
The design, construction, refueling and overhaul, repair, and inactivation of nuclear-powered aircraft carriers and nuclear-powered submarines, our nuclear facilities used to support such activities, our nuclear operations at DoE sites, and our activities in the commercial nuclear market subject us to various risks, including:


Potential liabilities relating to harmful effects on the environment and human health resulting from nuclear operations and the storage, handling, and disposal of radioactive materials, including nuclear assemblies and their components;
Unplanned expenditures relating to maintenance, operation,operations, security, and repair,repairs, including repairs required by the U.S. Navy, the Nuclear Regulatory Commission, or the DoE;
Reputational harm;damage;
Potential liabilities arising out of a nuclear incident whether or not it is within our control; and
Regulatory noncompliance and loss of authorizations or indemnifications necessary for our operations.


Failure to properly store, handle, and dispose of nuclear materials could pose a health risk to humans orand wildlife and could cause personal injury and property damage, including environmental contamination. If a nuclear accident were to occur, its severity could be significantly affected by the volume of the materials and the speed of corrective actionremedial actions taken by us and emergency response personnel, as well as other factors beyond our control, such as weather and wind conditions. Actions we might take in response to an accident could result in significant costs.


Our nuclear operations are subject to various safety related requirements imposed by the U.S. Navy, the DoE, and the Nuclear Regulatory Commission. In the event of noncompliance, these agencies may increase regulatory oversight, impose fines, or shut down our operations, depending on their assessment of the severity of the noncompliance. In addition, new or revised security and safety requirements imposed by the U.S. Navy, DoE, and Nuclear Regulatory Commission could necessitaterequire substantial capital and other expenditures.


Subject to certain requirements and limitations, our contracts with the U.S. Navy and DoE generally provide for indemnity by the U.S. Government for costs arising out of or resulting from our nuclear operations. We may not, however, be indemnified for all liabilities we may incur in connection with our nuclear operations. To mitigate risks related to our commercial nuclear operations, we rely primarily on insurance carried by nuclear facility operators and our own limited insurance for losses in excess of the coverage of facility operators. Such insurance, however, may not be sufficient to cover our costs in the event of an accident or business interruption relating to our commercial nuclear operations, which could have a material adverse effect on our financial position, results of operations, or cash flows.

Changes in future business conditions could cause business investments, recorded goodwill, and/or purchased intangible assets to become impaired, resulting in substantial lossestax laws and write-downs that would reduce our operating income.
As part of our business strategy, we acquire non-controlling and controlling interests in businesses. We make acquisitions and investments following careful analysis and due diligence processes designed to achieve a desired return or strategic objective. Business acquisitions generally involve estimates, assumptions, and judgments to determine acquisition prices, which prices are allocated among acquired assets, including goodwill, based upon fair market values. Notwithstanding our analyses, due diligence processes, and business integration efforts, actual operating results of acquired businesses may vary significantly from initial estimates. In such events, we may be required to write down our carrying value of the related goodwill and/or purchased intangible assets. In addition, declines in the trading price of our common stock or the market as a whole can result in goodwill and/or purchased intangible asset impairment charges.

As of December 31, 2017, goodwill and purchased intangible assets generated from prior business acquisitions accounted for approximately 19% and 8%, respectively, of our total assets. We evaluate goodwill values for impairment annually on November 30, or when evidence of potential impairment exists. We also evaluate the values of purchased intangible assets when evidence of potential impairment exists. The impairment tests are

based on several factors requiring judgment. As a general matter, a significant decrease in expected cash flows or changes in market conditions may indicate potential impairment of recorded goodwill or purchased intangible assets.

In 2015, we recorded goodwill impairment charges of $75 million at our Technical Solutions segment within the oil and gas reporting unit. The oil and gas reporting unit is sensitive to developments in the oil and gas industry. The goodwill impairment charges were primarily driven by continuing declines in oil prices and the resulting decreases in industry market multiples. In 2015, we also recorded an intangible asset impairment charge of $27 million at our Technical Solutions segment as a result of declining market conditions and updated expectations.
Adverse equity market conditions that result in a decline in market multiples and the trading price of our common stock, or other events, such as reductions in future contract awards or significant adverse changes in our operating margins or the operating results of acquired businesses that vary significantly from projected results on which purchase prices are based, could result in an impairment of goodwill or other intangible assets. Any such impairments that result in us recording additional goodwill or intangible asset impairment charges could have a material adverse effect on our financial position or results of operations.
Unanticipated changes in our tax provisionsregulations or exposure to additional income tax liabilities could adversely affect our profitability and cash flow.financial results.
We are subject to income taxes in various jurisdictions. Significant judgment is required in determining our provision for income taxes. In the ordinary course of business, the ultimate tax determination of many of our transactions and calculations is uncertain. In addition, timing differences in the recognition of contract income for financial statement purposes and for income tax purposes can cause uncertainty with respect to the timing of income tax payments, which can have a significant impact on cash flow in a particular period.


Changes in applicable incomeU.S. (federal or state) or foreign tax laws and regulations, or their interpretation and application, including those with retroactive effect, could result in higher or lower income tax rates or changesincreases in the taxability of certain transactions or the deductibility of certain expenses, thereby affecting our income tax expense and profitability. On December 22, 2017,affect profitability and cash flows. For example, beginning in 2022, the Tax Cuts and Jobs Act (the "Tax Act") was signed into law.of 2017 eliminates the option to deduct research and development expenditures immediately in the year incurred and requires taxpayers to capitalize and amortize such expenditures over five years. If these provisions are not deferred, modified, or repealed by Congress with retroactive effect to January 1, 2022, they will decrease our cash from operations beginning in 2022. We currently estimate an approximately $100 million impact to 2022 cash from operations based on the provisions currently in effect. The Tax Act provides for significant changesactual impact on 2022 cash from operations will depend on whether and when these provisions are deferred, modified, or repealed by Congress, including any retroactive application, and the amount of research and development expenses paid or incurred in 2022, among other factors. In addition, recent proposals to increase the U.S. Internal Revenue Code of 1986, as amended, that impact corporations, including a reduction of the statutory federal corporate income tax rate from 35%would require us to 21%increase our net deferred tax liabilities upon enactment of new tax legislation, with a corresponding material, one-time, noncash increase in deferred income tax expense. Our current income tax expense and changes or limitationspayments would likely materially increase in periods subsequent to certain deductions. While our accounting for elements of the Tax Act is incomplete, we were able to make reasonable estimates of the effects of certain provisions of the Tax Act and recorded corresponding provisional adjustments. There remain certain elements for which we cannot yet make reasonable estimates, however, and we cannot determine at this time the full effects in future years of the Tax Act on our financial position, results of operations, or cash flows. See Note 13: Income Taxes in Item 8.income tax rate change.


In addition to future changes in tax laws, the final resultsamount of anynet deferred tax audits or related litigation could be materially different from our related historical income tax provisions and accruals. Changes in our tax rateliabilities will change periodically as a result of changes ina number of factors, including the measurement of our overall profitability, changes in tax legislation,defined benefit pension plans, actual cash contributions to our defined benefit pension plans, changes in the valuationtiming of deferred tax assetscontract taxable income, and liabilities, changes in differences between financial statement incomethe amount and taxable income, thetiming of depreciation deductions. We are also regularly under audit or examination of previously filed tax returns by taxing authorities, and continuing assessmentsincluding
23


foreign tax authorities. The final determination of our tax exposures can also impact our tax liabilities and affectany related litigation could similarly result in unanticipated increases in our income tax expense and affect profitability and cash flow.flows.

We conduct a portion of our operations through joint ventures and strategic alliances. We may have limited control over such arrangements and experience returns that are not proportional to the risks and resources we contribute.
We conduct a portion of our operations through joint ventures with business partners. In any joint venture arrangement, differences in views among the joint venture participants may result in delayed decisions or in failures to reach agreement on major issues. We and our joint venture partners may, in certain instances, fail to reach agreement on significant decisions on a timely basis, or at all. We also cannot control the actions of our joint venture partners, including any non-performance, default, or bankruptcy of our joint venture partners, and we typically share liability or have joint and/or several liability with our joint venture partners for joint venture matters. Any of these factors could potentially have a material adverse effect on our joint venture operations and the profitability of our joint ventures.
In joint ventures in which we hold a minority interest, we have limited control over many decisions relating to joint venture operations and internal controls relating to operations. These joint ventures may not be subject to the same

requirements regarding internal controls and internal control reporting that apply to us. As a result, internal control issues may arise that could have a material adverse effect on the joint venture. In addition, in order to establish or preserve relationships with our joint venture partners, we may agree to assume risks and contribute resources that are proportionately greater than the returns we expect to receive in the related joint venture. Such agreements may reduce our income and returns on these investments compared to what we would have received if our assumed risks and contributed resources were proportionate to our returns.

Strategic acquisitions and investments we pursue involve risks and uncertainties.

As part of our business strategy, we review, evaluate, and consider potential acquisitions and investments. In evaluating such transactions, we make difficult judgments regarding the value of business opportunities, technologies, and other assets, the risks and costs of potential liabilities, and the future prospects of business opportunities. In addition, acquisitions and investments involve other risks and uncertainties, including the difficulty of integrating acquired businesses, challenges achieving strategic objectives and other benefits anticipated from acquisitions or investments, the diversion of management attention and resources from our existing operations and other initiatives, the potential impairment of acquired assets, and the potential loss of key employees of acquired businesses. Our financial results, business, and future prospects could be adversely affected by unanticipated performance issues at acquired businesses, transaction-related charges, unexpected liabilities, amortization of expenses related to purchased intangible assets, and charges for impairments of goodwill and purchased intangible assets.

We are subject to claims and litigation that could ultimately be resolved against us, requiring future material cash payments and/or future material charges against our operating income, materially impairing our financial position or cash flows.
 
The size, nature, and complexity of our business make it highly susceptible to claims and litigation. We are subject to various administrative, civil, and criminal litigation, environmental claims, income tax matters,proceedings, compliance matters,proceedings, customer claims, and audits and investigations, which couldcan divert financial and management resources and result in fines, penalties, compensatory, treble or other damages, or nonmonetary relief.sanctions. Government regulations also provide that certain allegations against a contractor may lead to suspension or debarment from government contracts or suspension of export privileges. Suspension or debarment could have a material adverse effect on us because of our reliance on government contracts and authorizations. Litigation, claims, or investigations, if ultimately resolved against us, could have a material adverse effect on our financial position, results of operations, or cash flows. Any litigation, claim, audit, or investigation, even if fully indemnified or insured, could negatively impact our reputation among our customers and the public and make it more difficult for us to compete effectively or obtainacquire adequate insurance in the future. See Note 14: Investigations, Claims, and Litigation in Item 8.
 
We may be unable to adequately protect our intellectual property rights, which could affect our ability to compete.

We own patents, trademarks, copyrights, and other forms of intellectual property related to our business, and we license intellectual property rights to and from third parties. The U.S. Government generally receives non-exclusive licenses to certain intellectual property we develop in the performance of U.S. Government contracts, and the U.S. Government may use or authorize others to use such intellectual property. The U.S. Government has begun asserting or seekingis taking increasingly aggressive positions both as to obtain more extensive rights inthe intellectual property associated with its contracts. Theto which they believe government use rights apply and to the acquisition of broad license rights. If the U.S. Government'sGovernment is successful in these efforts, could reduce our abilityintellectual property on which we depend and our access to control theand use of certain of oursupplier intellectual property rights in a government contracting environment. Our intellectual property is also subject to challenge, invalidation, misappropriation, or circumvention by third parties.could be negatively affected.
 
We also rely upon proprietary technology, information, processes, and know-how that are not protected by patents. We seek to protect this information through trade secret or confidentiality agreements with our employees, consultants, subcontractors, and other parties, as well as through other measures. These agreements and other measures may not, however, provide meaningful protection for our unpatented proprietary information.adequately protect the trade secrets on which we depend.


Our intellectual property is also subject to challenge, invalidation, misappropriation, or circumvention by third parties. In the event of infringement of our intellectual property rights, breach of a confidentiality agreement, or unauthorized disclosure of proprietary information, we may not have adequate legal remedies to maintain our rights inprotect our intellectual property. Litigation to determine the scope of our rights, even if successful, could be costly and a diversion of management's attention from other aspects of our business.attention. In addition, trade secrets may otherwise

become known or be independently developed by competitors. If we are unable adequately to protect our intellectual property rights, our business could be adversely affected.
 
We have the right toalso use certain intellectual property licensed to us by third parties. In instances where third parties havethe case of such licensed to us the right to use their intellectual property, we may be unable in the future to secure the necessary licenses to use such intellectual property, or to secure the licenses on commercially reasonable terms.


Anti-takeover provisions in our organizational documents and Delaware law, as well as regulatory requirements, could delay or prevent a change in control.
Certain provisions of our Restated Certificate of Incorporation and Restated Bylaws may delay or prevent a merger or acquisition that stockholders may consider favorable. For example, our Restated Certificate of Incorporation and Restated Bylaws currently require advance notice for stockholder proposals and director nominations, and authorize our board of directors to issue one or more series of preferred stock. These provisions may discourage acquisition proposals or delay or prevent a change in control, which could reduce our stock price. Delaware law also imposes restrictions on mergers and other business combinations between any holder of 15% or more of our outstanding common stock and us.

Our nuclear shipbuilding operations are considered vitally important to the U.S. Navy. As a result, our Navy contracts include notice and approval rights for the Navy and conditions regarding the Navy's obligations to indemnify us for losses relating to our naval nuclear operations, in the event of a change of control of our nuclear shipbuilding operations. Such provisions require us to provide the U.S. Navy with notice of any potential change of control of our nuclear shipbuilding operations and receive the Navy's consent for transferring certain related licenses to facilitate the Navy's ability to ensure that a potential buyer would continue to conduct our operations in a satisfactory manner.
Provisions of our Restated Certificate of Incorporation and our Restated Bylaws and our existing contracts with the U.S. Navy may have the effect of discouraging, delaying, or preventing a change of control of our company that may be beneficial to our stockholders.

General Risk Factors

Our insurance coverage may be inadequate to cover all of our significant risks or our insurers may deny coverage of material losses we incur, which could adversely affect our profitability and financial position.
We seek to insure our significant risks and potential liabilities that are insurable, including, among others, property loss from natural disasters, product liability, and business interruption resulting from an insured property loss. In some circumstances, we may be indemnified for losses by the U.S. Government, subject to the availability of appropriated funds. Not every risk or liability can be protected by insurance, and, for insurable risks, the limits of coverage we can reasonably purchase may not be sufficient to cover the full amount of our actual losses or liabilities, including, for example, in the case of a catastrophic hurricane. In addition, the nature of our business can make it difficult to quantify the disruptive impact and loss resulting from such events. Limitations on the availability of insurance coverage may result in substantial uninsured losses, which could have a material adverse effect on our financial position, results of operations, or cash flows. Even in cases for which we have insurance coverage, disputes with insurance carriers over coverage may affect the timing of cash flows, and, in the event of litigation with an insurance carrier, an unfavorable outcome may have a material adverse effect on our financial position, results of operations, or cash flows.

Market volatility and adverse capital market conditions may affect our ability to access cost-effective sources of funding and may expose us to risks associated with the financial viability of suppliers and subcontractors.

The financial markets can experience high levels of volatility and disruption, reducing the availability of credit for certain issuers. We access these markets from time to time to support certain business activities, including funding acquisitions and capital expansion projects and refinancing existing indebtedness. We may also access these markets to acquire credit support for our workers' compensation self-insurance program and letters of credit. A number of factors could cause us to incur higher borrowing costs and experience greater difficulty accessing public and private markets for debt, including disruptions or declines in the global capital markets and/or a decline in our financial performance, outlook, or credit ratings. The occurrence of any or all of these events may adversely affect our ability to fund our operations, meet contractual commitments, make future investments or desirable acquisitions, or respond to competitive challenges.
Tightening capital markets could also adversely affect the ability of our suppliers and subcontractors to obtain financing. Delays in the ability of our suppliers or subcontractors to obtain financing, or the unavailability of financing, could negatively affect their ability to perform their contracts with us and, as a result, our ability to perform our contracts. The inability of our suppliers and subcontractors to obtain financing could also result in the need for us to transition to alternate suppliers and subcontractors, which could result in us incurring significant incremental costs and delays.

If we fail to manage acquisitions, divestitures, equity investments, and other transactions, including our acquisition of Alion, successfully or if acquired entities or equity investments fail to perform as expected, our financial results, business, and future prospects could be harmed.

As part of our business strategy, we identify and evaluate potential acquisitions and investments. When evaluating such transactions, we make significant judgments regarding the values of business opportunities, technologies, and other assets, the risks and costs of potential liabilities, and the future prospects of strategic acquisitions. We often
25


compete with other potential buyers for the same opportunities. To be successful, we must conduct due diligence to identify valuation issues and potential loss contingencies; negotiate transaction terms; complete and close complex transactions; integrate acquired companies and employees; and realize anticipated operating synergies efficiently and effectively. Acquisition, divestiture, joint venture, and investment transactions often require substantial management resources and have the potential to divert our attention from our existing business. Unidentified or identified but un-indemnified pre-closing liabilities could affect our future financial results, particularly through successor liability under procurement laws and regulations, such as the False Claims Act or Truth in Negotiations Act, anti-corruption, environmental, tax, import-export, and technology transfer laws, which provide for civil and criminal penalties and the potential for debarment. We also may incur unanticipated costs or expenses, including post-closing asset impairment charges, expenses associated with eliminating duplicate facilities, employee retention, transaction-related or other litigation, and other liabilities. Any of the foregoing could adversely affect our business and results of operations.

Joint ventures and other non-controlling investments operate under shared control with other parties. These investments typically face many of the same risks and uncertainties as we do, but may also expose us to additional risks not present if we retained full control. A joint venture partner may have economic or other business interests that are inconsistent with our interests, and we may be unable to prevent strategic decisions that may adversely affect our business, financial condition, and results of operations. We also could be adversely affected by, or liable for, actions taken by these joint ventures that we do not control, including violations of anti-corruption, import and export, taxation, and anti-boycott laws.

There can be no assurance we will continue to increase our dividends or to repurchase shares of our common stock at current levels.


The payment of cash dividends and repurchases of our common stock are subject to limitations under applicable law and the discretion of our board of directors, considered in the context of then current conditions, including our earnings, other operating results, and capital requirements. Declines in asset values or increases in liabilities, including liabilities associated with benefit plans and assets and liabilities associated with taxes, can reduce stockholders’ equity. A deficit in stockholders’ equity could limit our ability under Delaware law to pay dividends and repurchase shares in the future. In addition, the timing and amount of share repurchases under board approvedboard-approved share repurchase programs isare within the discretion of management and will depend upon many factors, including our share price, results of operations, and capital requirements, and general business conditions, as well as applicable law.


Our debt exposes us to certain risks.

As of December 31, 2017, we had $1,279 million of debt under our senior notes and $1,235 million of additional borrowing capacity under our Credit Agreement (the “Credit Facility”). Our Credit Facility also allows us to solicit lenders to provide incremental financing in an aggregate amount not to exceed $1,000 million, and the indentures governing our senior notes do not limit our incurrence of debt. The amount of our existing debt, combined with our ability to incur significant amounts of debt in the future, could have important consequences, including:

Increasing our vulnerability to adverse economic or industry conditions;
Requiring us to dedicate a portion of our cash flow from operations to payments on our debt, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, strategic initiatives, and general corporate purposes;
Increasing our vulnerability to, and limiting our flexibility in planning for, or reacting to, changes in our business or the industries in which we operate;
Exposing us to the risk of higher interest rates on borrowings under our Credit Facility, which are subject to variable rates of interest;
Placing us at a competitive disadvantage compared to our competitors that have less debt; and
Limiting our ability to borrow additional funds.

To the extent new debt is added to our current debt levels, the related risks that we face could be increased.

Anti-takeover provisions in our organizational documents and Delaware law, as well as regulatory requirements, could delay or prevent a change in control.
Certain provisions of our Restated Certificate of Incorporation and Restated Bylaws may delay or prevent a merger or acquisition that stockholders may consider favorable. For example, our Restated Certificate of Incorporation and Restated Bylaws currently require advance notice for stockholder proposals and director nominations, and authorize our board of directors to issue one or more series of preferred stock. These provisions may discourage acquisition proposals or delay or prevent a change in control, which could harm our stock price. Delaware law also imposes restrictions on mergers and other business combinations between any holder of 15% or more of our outstanding common stock and us.

Our nuclear shipbuilding operations are considered vitally important to the U.S. Navy. Consequently, the U.S. Navy requires us to include in our contracts with the Navy provisions regarding notice and approval rights for the Navy in the event of a change of control of our nuclear shipbuilding operations and regarding the Navy's obligations to indemnify us for losses relating to our nuclear operations for the Navy.  Such provisions require us to provide the U.S. Navy with notice of any potential change of control of our nuclear shipbuilding operations and obtain the Navy's consent for transferring certain related licenses in order to facilitate the Navy's ability to ensure that a potential buyer would continue to conduct our operations in a satisfactory manner. We have included such

provisions in solicitations for future U.S. Navy nuclear work, and we expect them to be included in future contracts with the Navy for nuclear work.
Provisions of our Restated Certificate of Incorporation and our Restated Bylaws and our existing contracts with the U.S. Navy may have the effect of discouraging, delaying, or preventing a change of control of our company that may be beneficial to our stockholders.

ITEM 2. PROPERTIES


Our principal properties are located in Huntsville, Alabama; San Diego, California; Broomfield, Colorado; Avondale (New Orleans), Louisiana; Pascagoula, Mississippi; Houston, Texas; Fairfax, Hampton, Newport News, Suffolk, and Virginia Beach, Virginia; and Washington, D.C.
Ingalls - The primary properties comprising our Ingalls operating segment are located in Pascagoula, Mississippi, and Avondale, Louisiana.Mississippi.


Our Pascagoula shipyard is a primary builder of major surface warships for the U.S. Navy and has modernized dozens of other naval ships. It is the only U.S. shipyard in recent years to develop and build six different classes of ships for the U.S. Navy and U.S. Coast Guard. Our facilities in Pascagoula are located on approximately 800 acres on the banks of the Pascagoula River where it flows into the Mississippi Sound. We lease the west bank of our Pascagoula shipyard from the State of Mississippi pursuant to a 99-year lease, consisting of a 40-year base term plus six optional terms. We anticipate continued use of this facility for the remaining 4945 years of the lease and beyond.

In October 2014, we ceased shipbuilding construction operations at the Avondale facility. Our Avondale shipyard is located on approximately 268 acres on the banks of the Mississippi River, approximately 12 miles upriver from downtown New Orleans. Approximately 20% of the Avondale shipyard is leased from several third parties. The leases have varying expiration dates and typically contain renewal rights. Effective July 31, 2017, we entered into a Purchase and Sale Agreement with a potential buyer of the Avondale facility. After conducting due diligence on the property, the potential buyer has the right to determine whether or not to proceed to closing.

Newport News - The primary properties comprising our Newport News operating segment are located in Newport News, Virginia. 


Our Newport News facilities are located on approximately 550 acres we own near the mouth of the James River, which adjoins the Chesapeake Bay, the premier deep-water harbor on the east coast of the United States. Our Newport News shipyard is one of the largest in the United States. It is the sole designer, builder,States and refueler of nuclear-powered aircraft carriers and one of only two shipyards capable of designing and building nuclear-powered submarines for the U.S. Navy. The shipyard also provides services for naval and commercial vessels.

Our Newport News shipyard includes seven graving docks, a floating dry dock, two outfitting berths, five outfitting piers, and various other shops. It also has a variety of other facilities, including an 18-acre all-weather steel fabrication shop, accessible by both rail and transporter, module outfitting facilities that enable us to assemble a ship's basic structural modules indoors and on land, machine shops totaling

While our physical facilities and equipment are adequate for our current needs, weWe have initiatedundertaken substantial capital expenditure programs at our Ingalls and Newport News segments that will make us more competitiveintended to increase our competitiveness and enable us to meet future obligations under our growing shipbuilding programs.program backlog.


ITEM 3. LEGAL PROCEEDINGS


U.S. Government Investigations and Claims - Departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of our 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 likely have a material adverse effect on us because of our reliance on government contracts.

In January 2013, we disclosed to the DoD, including the U.S. Navy, and the U.S. Department of Homeland Security, including the U.S. Coast Guard, pursuant to the FAR, that we had initiated an internal investigation regarding whether certain employees at Ingalls mischarged time or misstated progress on Navy and Coast Guard contracts. We conducted an internal investigation, led by external counsel, and took remedial actions, including the termination of employees in instances where we believed grounds for termination existed. We providedFor information regarding our investigation to the relevant government agencies, and agreed with the U.S. Navy and U.S. Coast Guard that they would initially withhold $24 million in payments on existing contracts pending receipt of additional information from our internal investigation. The U.S. Navy subsequently reduced its portion of the withhold from $18.2 million to $4.7 million, and the U.S. Coast Guard reduced its withhold from $5.8 million to $3.6 million. In September 2017, the U.S. Navy and the U.S. Coast Guard paid us the respective remaining amounts they were withholding.

In June 2015, the U.S. Department of Justice ("DoJ") informed us that it was investigating the matters we disclosed to the DoD in January 2013. In August 2017, we settled the matters with the DoJ. The settlement did not have a material effect on our consolidated financial position, results of operations, or cash flows.

Litigation - In 2015, we received a Civil Investigative Demand from the DoJ relating to an investigation of certain allegedly non-conforming parts we purchased from one of our suppliers for use in connection with U.S. Government contracts. We have cooperated with the DoJ in connection with its investigation. In 2016, we were made aware that we are a defendant in a False Claims Act lawsuit filed under seal in the U.S. District Court for the Middle District of Florida related to our purchase of the allegedly non-conforming parts from the supplier. Depending upon the outcome of this matter, we could be subject to civil penalties, damages, and/or suspension or debarment from future U.S. Government contracts, which could have a material adverse effect on our consolidated financial position, results of operations, or cash flows. The matter remains sealed and given the current posture of the matter, we are unable to estimate an amount or range of reasonably possible loss or to express an opinion regarding the ultimate outcome.

We and our 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, in which former and current employees and various third parties allege exposure to asbestos-containing materials while on, or associated with, our premises or while working on vessels constructed or repaired by us. 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 our former executive officers are also named as defendants. In some instances, partial or full insurance coverage is available to us for our liability and that of our former executive officers. Although we believe the ultimate resolution of current cases will not have a material effect on our consolidated financial position, results of operations, or cash flows, we 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.

We and our 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. The case proceeded towards arbitration, then appeared to settle favorably, but the settlement was overturned in court and the matter returned to litigation. In March 2014, we filed an arbitral statement of claim asserting breaches of the contract and $173 million in damages plus substantial interest and litigation expenses. In

July 2014, the Republic filed in the arbitration a statement of defense denying all our allegations and a counterclaim alleging late redelivery of the frigates, unfinished work, and breach of warranty and asserting damages of $61 million plus interest. An arbitration hearing was held in January 2015, and we cannot predict when the arbitration panel will render a decision. No assurances can be provided regarding the ultimate outcome of this matter.

We are party to various other claims and legal proceedings, that arisesee Note 14: Investigations, Claims, and Litigation in the ordinary course of business. Although we believe that the resolution of these other claims and legal proceedings will not have a material effect on our consolidated financial position, results of operations, or cash flows, we 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.Item 8.

The following discussion should be read along with the audited consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.


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
29


impacted our operations, and the extent of future impacts are uncertain. The most significant areas of impact have been the disruption of 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.

In August 2011, the BCA established limits onSeptember 2021, President Biden issued an executive order requiring certain employers with U.S. Government discretionary spending,contracts to ensure that their U.S.-based employees, contractors, and subcontractors that work on or in support of U.S. Government contracts are fully vaccinated in accordance with the guidelines of the Safer Federal Workforce Task Force. In November 2021, OSHA issued an Emergency Temporary Standard (“ETS”) requiring that all employers with 100 or more employees mandate vaccines for covered employees or, in the alternative, weekly testing and masks. The U.S. federal contractor mandate was preliminarily enjoined by several U.S. federal district courts, the U.S. Supreme Court preliminarily stayed the OSHA ETS in January 2022, and OSHA subsequently withdrew the ETS.

While we are not currently subject to any vaccine mandate, it continues to be our policy to encourage each of our employees to be fully vaccinated against COVID-19. To the extent we become subject to a vaccine mandate in the future, our implementation of the mandate could result in employee attrition, including attrition of critical skilled labor, and difficulty meeting future labor requirements.

See Risk Factors in Item 1A for a reductiondiscussion of defense spending by approximately $487 billion for fiscal years 2012 through 2021. The BCA also provided that the defense budget would face “sequestration” cuts of up to an additional $500 billion during that same period,COVID-19-related risks.

We have aggressively managed our response to the extentuncertainties regarding COVID-19 Events, and we have incurred costs to respond to COVID-19 Events, including paid leave, quarantining employees, vaccinations, and recurring facility cleaning. Our shipyards and other facilities have remained open and productive, but we continue to experience decreases in workforce attendance and challenges meeting our hiring requirements, which has impacted our operations due to delay and disruption from a shortage of critical skills and out-of-sequence work.

Under Section 3610 of the Coronavirus Aid, Relief, and Economic Security Act (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, paid time for employee vaccinations or responding to side effects from vaccination, 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, and we submitted an initial Section 3610 Reimbursement Request to the DoD for Ingalls and Newport News Shipbuilding. Section 3610 under the CARES Act was not extended past September 30, 2021. We anticipate submitting supplemental requests for Section 3610 reimbursement for HII and our subcontractors into 2022. Reimbursements of our requests are contingent upon contracting officers making funding available, and most DoD contracting officers are awaiting supplemental appropriations from Congress before approving such reimbursement requests. We have no assurance that discretionary spending limitsCongress will appropriate sufficient funds to cover the reimbursement of costs contemplated by the CARES Act.

While costs related to COVID-19 Events are exceeded,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 $500 billionfixed-price incentive contracts, or may not be adequately covered by insurance. Our reinsurers have failed to acknowledge coverage for non-defense discretionary spending, includingvarious 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. The Vermont court dismissed our complaint in response to a motion of the reinsurers for judgment on the pleadings, and we have appealed the decision. Although we continue to believe that our position is well-founded, no assurance can be provided regarding the ultimate resolution of this matter. See Note 14: Investigations, Claims, and Litigation in Item 8.

We have also focused on actively supporting our customers, suppliers, and communities. We have been proactive in engaging with our U.S. Coast Guard.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 also accelerated payments to small business suppliers in an effort to minimize supply chain disruption.

The BBA 2018 provided sequestration relief for fiscal years 2018
We temporarily halted stock repurchases in the first quarter of 2020, but we resumed share repurchases during the first quarter of 2021. We also deferred certain payroll taxes in 2020 pursuant to the CARES Act, which increased our cash from operations in 2020, but will reduce cash from operations in 2021 and 2019 and raised the budget topline for defense and non-defense discretionary spending. However, sequestration remains in effect for fiscal years 2020 and 2021.2022.

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


WeThe National Defense Authorization Act for Fiscal Year 2022 was enacted in December 2021 and broadly supports our shipbuilding programs, including increased funding authority for Arleigh Burke-class destroyers (DDG-51), LHA and LPD Flight II amphibious ships, and submarine supplier development assistance. However, more than one quarter into the fiscal year, Congressional appropriations for the federal government have yet to be finalized. Consequently, the U.S. Government is currently operating under a Continuing Resolution ("CR") that funds government operations through February 18, 2022. It remains uncertain at this point whether fiscal year 2022 government operations will require additional short-term funding or annual appropriations measures will be finalized prior to the expiration of the CR. Appropriations measures must be passed by Congress and enacted by the President, and we cannot predict the impact that sequestration cuts or reprioritizationoutcome of readiness and modernization investment may have on funding for our individual programs. the fiscal year 2022 budget process.

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 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 federal budget environment including sequestration as currently mandated, 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 that result from sequestration and other budget priorities will have serious implications for defense discretionary spending, the defense industrial base, including us,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. Congress and the new Administration continue to discuss various options to address sequestration in future budget planning, but we cannot predict the outcome of these efforts. It is likely budget and program decisions made in this environment will have long-term impacts on usHII and the entire defense industry.



Defense Industry Overview
 
The United States faces a complex, uncertain, and rapidly changing national security environment. Upon assuming office in 2021, the Biden Administration released a broad interim National Security Strategy that lays out the contours of U.S. foreign policy over the next four years. Under this strategy, the Indo-Pacific region remains at the heart of U.S. defense planning. While the United States continues to face security challenges from Russia, North Korea, and non-state extremism, other ‘non-traditional’ threats such as pandemic disease and climate change, are now part of the national security dialogue.

The 2018 National Defense Strategy acknowledges an increasingly complex global security environment, characterized by overt challenges to the free and open international order and the re-emergence of long-term, strategic competition between nations. AmericaU.S. also faces an evera more lethal and disruptive battlefield, combined across domains and conducted at increasing speed and reach. The security environment is also affected by rapid technological advancements and the changing character of war. The drive to develop new technologiescapabilities and enhance lethality is relentless, expanding to moreaddress emerging threats from peer-competitors as well as actors with lower barriers of entry, and moving at accelerating speed. New technologies include advanced computing, “big data” analytics, artificial intelligence, autonomy, robotics, directed energy, hypersonics, and biotechnology.

States areTo address these rapidly-evolving threats, the principal actors on the global stage, but non-state actors also threaten the security environment with increasingly sophisticated capabilities. Terrorists, trans-national criminal organizations, cyber hackers, and other malicious non-state actors have increased capabilities of mass disruption. Terrorism remains a persistent condition driven by ideology and unstable political and economic structures.

We expect that the DoD execution of its strategy will require an affordable balance between investments in restoring the readiness of the current force with investmentsU.S. is investing in new capabilities technologies, and capacity to meet future challenges. The DoD faces the additional challenge of recapitalizing equipmentlethality enhancements, including unmanned and rebuilding readiness at a time when the DoD is pursuing modernization of its capabilities, while still facing additional budget cuts from sequestration. While the BBA 2018 provided relief for fiscal years 2018autonomous systems and 2019, it is unclear how sequestration could impact programs forplatforms; artificial intelligence; hypersonics; directed energy; resilient networks; command, control, communications, computers, cyber, intelligence, surveillance and reconnaissance; and targeting requirements and microelectronics. Technologies are being prioritized that can penetrate and operate inside highly-contested and highly-defended territory, both physical and cyber.

In late December 2020, and beyond. BCA spending caps, coupled with other budget priorities, could have a significant impact on future spending plans for defense and non-defense discretionary programs. Decreases in the proposed funding levels for our programs could negatively impact our financial position, results of operations, or cash flows, including revenues, goodwill, and long-lived assets.

In December 2016, the U.S. Navy, Marine Corps, and Coast Guard released a Tri-Service Maritime Strategy titled Advantage at Sea. The document provides strategic guidance on how the findingssea services will prevail in day-to-day competition, crisis, and conflict over the next decade. The strategy directs the services to pursue an agile and aggressive approach to force modernization and experimentation by combining legacy assets with new capabilities
31


to understand faster, decide faster, and act faster. The strategy also emphasizes the need to develop new operational concepts for fielded capabilities, employ resilient and integrated networks across the force, leverage the strengths of regional partners, and expand the use of optionally manned and unmanned platforms.

In January 2021, the Chief of Naval Operations released a year-longNavigation Plan to the Fleet that nests under the Tri-Service Maritime Strategy and outlines how the U.S. Navy will grow its naval power to control the seas and project power across all domains. It lays out what must be done this decade to deliver the naval power America needs to compete and win, characterized as a ready fleet, a more lethal and better-connected fleet, and a larger more hybrid fleet. To this end, the Marine Corps is also reshaping its force under the Commandant’s Force Design 2030 guidance to become optimized for modern operations by 2030. The Marine Corps has already taken action to eliminate legacy capabilities, such as battle tanks, and a future force may feature an expanded assortment of smaller platforms, landing craft, and connectors that are manned, minimally manned, and unmanned, and exploit autonomy and artificial intelligence.

We anticipate the U.S. Navy’s force projection strategy will continue to emphasize sea control and sea denial, enabling power projection against adversaries with long-range weapons and full-spectrum joint domain capabilities. The Navy will likely continue to employ the evolving concept of Distributed Maritime Operations ("DMO"), which features multiple sensors and shooters that are widely dispersed across a broad range of manned and unmanned platforms and linked through resilient networks. Naval forces are participating in a larger DoD-wide objective to modernize command and control architecture, the concept to connect sensors from all of the military services into a single network known as Joint All-Domain Command and Control ("JADC2"). Future conflicts may require leaders to analyze the operating environment and make decisions rapidly. With JADC2, DoD envisions creating an “internet of things” network that would connect numerous sensors with weapons systems, using artificial intelligence algorithms to help improve decision-making. Project Overmatch is the Navy’s effort to develop the networks, infrastructure, data architecture, and analytics to participate in this larger, networked military operating environment. The end-state for the “Future Navy” envisions a fleet designed to ensure the wholeness of combat capability and lethal forces maximizing the benefits of DMO, expeditionary advanced base operations, and littoral operations in a contested environment. Manned and unmanned technology will be used to expand reach, lethality, and warfighter awareness.

The Navy’s force structure goal of 355 ships, identified in the December 2016 Force Structure Assessment developed to determineand codified in the right balance of existing forces, the ships currently under construction, and the future procurement plans needed to address the ever-evolving and increasingly complex threats that the Navy is required to counter. Notably, the Force Structure Assessment did not present a desired force size the U.S. Navy would pursue if resources were not constrained; it reflected a force level that balances warfighting risk to equipment and personnel against available resources and recommends a force size that can reasonably achieve success. Accordingly, the Force Structure Assessment reflects an objective force of 355 ships, comprised of 12 aircraft carriers, 104 large surface combatants, 52 small surface combatants, 38 amphibious warfare ships, 66 attack submarines, 12 ballistic missile submarines, 32 combat logistics ships, 10 expeditionary/high speed transports, 6 expeditionary support bases, and 23 command and support ships. Additionally, thefiscal year 2018 National Defense Authorization Act, includedhas remained the SHIPS Act, which made itfleet objective for five years. The Navy and the policy of our nationDoD have been working to achievedevelop a fleet size of 355 ships. It remains unclear, however, whethersuccessor for the 2016 Force Structure Assessment or355-ship force-level goal. In December 2020, the requirementsoutgoing Administration released its vision for the Navy’s future force structure in a fiscal year 2022 30-year Navy shipbuilding plan. The plan envisioned achievement of the SHIPS Act will have any bearing on budget outcomes forNavy’s force-level goal through a distributed fleet architecture, including 382 to 446 manned ships and 143 to 242 large unmanned vehicles by 2045. The new Administration did not submit a new force structure goal or shipbuilding plan in 2021, but is expected to do so with the delivery of the fiscal year 20192023 budget in spring 2022.

The Defense Department and beyond.

Navy not only face difficult tradeoffs between modernization priorities, but also tradeoffs about where to take risk across time. The shipbuilding defense industry as characterized by its competitors, customers, suppliers, potential entrants, and substitutes, is unique in many ways. It is heavily capital heavy and skilled labor intensive. The U.S. Navy, a large single customer with many needs and requirements, dominates the industry's customer base and is served by aan increasingly fragile supplier base that has trended toward exclusive providers. SmallerInconsistent shipbuilding plans and annual funding uncertainty severely degrade the ability of shipyards however, have enteredto conduct long-term planning and respond to near-term changes in requirements. This ultimately results in longer construction times and increased costs. For example, the markethigh operational tempo of the Navy in recent years has resulted in a backlog of repair work across the fleet. Coupled with the impacts of COVID-19 and increases in new ship construction, many suppliers are experiencing a shortfall in their capacity to buildperform work and manufacture products. This increased demand is applying stress to already-aging production equipment. The combination of limited suppliers and an increase in workload could increase cost and potentially create schedule slips, impacting American warfighting capability.

Ultimately, a balance will need to be achieved between the U.S. Navy's littoral combat ship. Thecompeting priorities of upgrading legacy systems for the near-term, developing and procuring the next generation of systems for the mid-term, and investing in emerging technologies that could drive game-changing capabilities in the long-term. Additionally, the U.S. Navy must compete with other nationalbudget priorities, including other defense activities, non-defense discretionary spending, supplemental spending for COVID-19 relief, and entitlement programsfor a share of federal budget funding.

The Administration has focused on regulatory reform in order to manage the costs associated with the governmental imposition of private expenditures required to comply with federal regulations. Additionally, an Executive Order issued in February 2017 requires that for every new regulation issued, at least two prior regulations must be identified for elimination, and that the cost of planned regulations be prudently managed and controlled through a budgeting process. The DoD continues to adjust its procurement practices and streamline acquisition organizations and processes in an ongoing effort to reduce costs, gain efficiencies, and enhance program management and control. While the impact to our business resulting from these initiativesdevelopments remains uncertain, they could have a material impact on current programs, as well as new business opportunities with the DoD.

For convenience, a brief description of certain programs discussed in this Annual Report on Form 10-K is included in the Glossary of Programs.


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 FAR and 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, organizational costs, including certain merger and acquisition costs, 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 DCAA routinely audits the costs we incur that are allocated to contracts with the U.S. Government.Government contracts.


Our long-term contracts typically fall into one of two broadfour categories:

Flexibly-Priced Contracts - Includes both firm fixed-price, fixed-price incentive, cost-type, and time and materials. See Note 7: Revenue in Item 8.

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.

Fixed-Price Incentive Contracts - Fixed-price incentive contracts.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. Fixed-price incentive contracts also 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. Approximately 92%, 94%,

Time and 95% of our revenues for the years endedDecember 31, 2017, 2016, and 2015, respectively, were generated from flexibly-priced contracts, including certain fixed-price incentive contracts that have exceeded their cost-share limit.

Firm Fixed-Price Contracts Materials - 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. Time and materials contracts which specify a fixed hourly billing rate for each direct labor hour charged, are considered firm fixed-price contracts. Approximately 8%, 6%,expended and 5% of our revenuesreimbursement for the years endedDecember 31, 2017, 2016,allowable material costs and 2015, respectively, were generated from firm fixed-price arrangements.
expenses.


Contract Fees - Negotiated contract fee structures for both flexibly-priced and firm fixed-price contracts include: fixed fee amounts, cost sharing arrangements to reward or penalize contractors for underunder- or over costover-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. Fees that weWe 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 reasonably assuredlimited to the extent of collectingfunding allotted by the customer and can be reasonably estimated are recorded over theavailable for performance periodand those amounts for which a significant reversal of the contract.revenue is not probable.


CRITICAL ACCOUNTING POLICIES, ESTIMATES, AND JUDGMENTS


Our consolidated financial statements are prepared in accordance with U.S. GAAP, which requires management to make estimates, judgments, and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Management considers an accounting policy to be critical if it is important to our financial condition and results of operations and requires significant judgment and estimates by management in its application. The development and selection of these critical accounting policies have been determined by our management. We have reviewed our critical accounting policies and estimates with the audit committee of our
33


board of directors. Due to the significant judgment involved in selecting certain of the assumptions used in these

policies, it is possible that different parties could choose different assumptions and reach different conclusions. While we base estimates and assumptions on our knowledge of current events and actions we may undertake in the future, actual results may ultimately differ from these estimates and assumptions. We consider theour policies relating to the following matters to beinvolve our most critical accounting policies:policies and estimates:


Revenue recognition;
Purchase accounting, goodwill, and intangible assets;
Litigation, commitments, and contingencies;
Retirement related benefit plans; and
Workers' compensation.

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: Summary of Significant Accounting Policies in Item 8.

Revenue Recognition

Overview - Most of our revenues are derived from long-term contracts for the production of goods and services provided to the federal government,U.S. Government, which are generally accounted for in conformity with GAAP for construction-type and production-type contracts and federal government contractors. We have other types of contracts, such as services and commercial arrangements, for whichby recognizing revenues are recognized upon delivery or as services are rendered once persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectibility is reasonably assured. Costs related to these contracts are expensed as incurred. We classify contract revenues as product sales or service revenues depending on the predominant attributes of the relevant underlying contracts. We consider the nature of these contracts and the types of products and services provided when determining the proper accounting method forover time using a particular contract.
Percentage-of-Completion Accounting - We generally recognize revenues from our long-term contracts under the cost-to-cost measure of the percentage-of-completion method of accounting. The percentage-of-completion method recognizes income as work onprogress. In estimating contract costs, we utilize a contract progresses. For most contracts, we calculate sales based on the percentage of costs incurred in relation to total Estimated Costs at Completion of the contract ("EAC"). For certain contracts with large up-front purchases of material, sales are calculated based on the percentage that direct labor costs incurred bear to total estimated direct labor costs at completion. For certain contracts that provide for deliveries of a substantial number of similar units, sales are accounted for using units of delivery as the basis to measure progress toward completion.

The use of the percentage-of-completion method depends on our ability to make reasonably dependable cost estimates for the design, manufacture, and delivery of our products and services. Such costs are typically incurred over a period of several years, and estimation of these costs requires the use of judgment. We record sales under cost-type contracts as costs are incurred.

Many contracts contain positive and negative profit incentivesprofit-booking rate based upon performance relative to predetermined targetsexpectations that may occur during or subsequent to deliverytakes into consideration a number of the product. These incentives take the form of potential additional fees to be earned or penalties to be incurred. Incentivesassumptions and award fees that we are reasonably assured of collecting and can be reasonably estimated are recorded over the performance period of the contract. Incentives and award fees that we are not reasonably assured of collecting or cannot be reasonably estimated are recorded when awarded or at such time as a reasonable estimate can be made.

At the start of each contract, we estimate an initial profit-booking rate that considersestimates regarding risks related to technical requirements, and feasibility, schedule, and contract costs. Management then performs periodic reviews of ourthe contracts in order to evaluate technical matters, schedule, and contract costs. During the life of a contract,underlying risks, which may increase the profit-booking rate may increase as we are able to mitigate and retire risks in connection with technical matters, schedule, and contract costs. Conversely, if we are not able to retire these risks, our EAC may increase, resulting in a lower profit-booking rate.

Changessuch risks. For the impacts of changes in estimates of contract sales, costs, and profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes in current and prior periods. Hence, the effect of the changes in future periods of contract performance is recognized as if the revised estimate had been the original estimate. A significant change in an estimate on one or more contracts in a period could have a material effect on our consolidated financial position or resultsstatements of operations for that period.and comprehensive income, see Note 8: Segment Information in Item 8.


For the years endedDecember 31, 2017, 2016, and 2015, favorable and unfavorable cumulative catch-up adjustments were as follows:
  Year Ended December 31
($ in millions) 2017 2016 2015
Gross favorable adjustments $309
 $297
 $304
Gross unfavorable adjustments (105) (73) (65)
Net adjustments $204
 $224
 $239

For the year ended December 31, 2017, favorable cumulative catch-up adjustments were primarily related to risk retirement on the Legend class NSC program, Tripoli (LHA 7), Portland (LPD 27), and the delivered USS John Finn (DDG 113), the resolution of outstanding contract changes on the inactivation of the decommissioned Enterprise (CVN 65) and the RCOH of the redelivered USS Abraham Lincoln (CVN 72), and other individually insignificant adjustments. During the same period, none of the unfavorable cumulative catch-up adjustments were individually significant.

For the year ended December 31, 2016, favorable cumulative catch-up adjustments were primarily related to risk retirement on USS John P. Murtha (LPD 26), the Virginia class (SSN 774) submarine program, Portland (LPD 27), the Legend class NSC program, and the Arleigh Burke class (DDG 51) destroyer program. During the same period, unfavorable cumulative catch-up adjustments included lower performance on the RCOH of USS Abraham Lincoln (CVN 72) and construction of Gerald R. Ford (CVN 78), as well as other individually insignificant adjustments.

For the year endedDecember 31, 2015, favorable cumulative catch-up adjustments were primarily related to risk retirement on the Virginia class (SSN 774) submarine program, the Legend class NSC program, and the San Antonio class (LPD 17) program, including delivered ships, the resolution of outstanding contract changes on the America class (LHA 6) program and the RCOH of USS Theodore Roosevelt (CVN 71), and contract impacts of the Aon litigation settlement. During the same period, unfavorable cumulative catch-up adjustments included lower performance on Gerald R. Ford (CVN 78), as well as other individually insignificant adjustments.

Cost Estimation - The cost estimation process requires significant judgment and is based upon the professional knowledge and experience of our engineers, program managers, and financial professionals. Factors we consider in estimating the work to be completed and ultimate contract recovery include the availability, productivity, and cost of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability of materials, the effect of any delays in performance, the availability and timing of funding from the customer, and the recoverability of any claims included in the estimates to complete. A significant change in an estimate on one or more contracts in a period could have a material effect on our consolidated financial position or results of operations for that period, and, where such changes occur, separate disclosure is made of the nature, underlying conditions, and financial impact of the change. We update our contract cost estimates at least annually and more frequently as determined by events or circumstances. We review and assess our cost and revenue estimates for each significant contract on a quarterly basis.

We record a provision for the entire loss on a contract in the period the loss is determined when estimates of total costs to be incurred on the contract exceed estimates of total revenues to be earned. We offset loss provisions first against costs that are included in unbilled accounts receivable or inventoried costs, with any remaining amount reflected in other current liabilities.


Purchase Accounting, Goodwill, and Intangible Assets

Purchase Accounting and Goodwill - Goodwill representsWe allocate the purchase price paid in excess of acquired businesses to the fair value of identifiable netunderlying tangible and intangible assets acquired and liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. We recognize purchased intangible assets in aconnection with our business combination.acquisitions at fair value on the acquisition date. The most significant purchased intangible assets recognized from our acquisitions are generally related to customer contracts, including backlog and recompeted contracts. We determine the fair values of those customer related intangible assets based on estimates and judgments, including the amount and timing of expected future cash flows, long-term growth rates, and discount rates.

Goodwill is tested for impairment on an annual basis at each of our goodwill as of December 31, 2017 and 2016, was $1,217 million and $1,234 million, respectively. During the year ended December 31, 2017, we recorded a goodwill adjustment of $17 million in the Technical Solutions segment, primarily drivenreporting units by the finalization of fair value calculations for certain assets and liabilities, as well as the net working capital adjustment, related to the acquisition of Camber.

Tests for Impairment - We perform impairment tests for goodwill as of November 30 of each year, or when evidence of potential impairment exists. When testing goodwill, we comparecomparing the fair value of the reporting unit to its carrying

value. If the fair value of the reporting unit is determined to be less than the carrying value, we record a charge to operations.


We estimate the fair value of each reporting unit using a combination of discounted cash flow analysis and market basedmarket-based valuation methodologies. Determining fair value requires the exercise of significant judgment, including judgments about projected revenues, operating expenses, working capital investment, capital expenditures, and cash flows over a multi-year period. The discount rate applied to our forecasts of future cash flows is based on our estimated weighted average cost of capital. In assessing the reasonableness of our determined fair values, we evaluate our results against our market capitalization. Impairment assessment inherently involves management judgments as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Changes in theseour estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit.


November 30, 2017 Impairment Test - In connection with our annual goodwill impairment test, we tested goodwill for each of our four reporting units. As a result of our annual goodwill impairment test, we determined that the estimated fair value of each reporting unit exceeded by more than 10% its corresponding carrying value as of November 30, 2017.

November 30, 2016 Impairment Test - In connection with our annual goodwill impairment test, we tested goodwill for each of our four reporting units. As a result of our annual goodwill impairment test, we determined that the estimated fair value of each reporting unit exceeded by more than 10% its corresponding carrying value as of November 30, 2016.

In conjunction with the realignment of our operations on December 1, 2016, we allocated goodwill among new and realigned reporting units based on the relative fair values of the reporting units being realigned. As a result, during the fourth quarter of 2016, we performed a quantitative assessment of goodwill immediately after the realignment for each of the reporting units impacted by our realignment. Based on this quantitative assessment, no impairment charge was necessary as a result of the realignment.

November 30, 2015 and December 31, 2015 Impairment Tests - We performed our annual goodwill impairment test as of November 30, 2015, and, while the annual impairment test did not result in an impairment, considering the limited excess fair value of goodwill over its carrying value in our oil and gas reporting unit and the continued decline in oil prices and related industry activity levels, we performed an interim assessment of goodwill as of December 31, 2015. Our determination of fair value as of December 31, 2015, considered industry events that occurred in the period since our annual goodwill impairment test, as well as the updated long term outlook for this reporting unit. Those events included continued deterioration in the oil and gas markets, numerous industry-wide project deferrals, and capital spending cuts announced by industry leaders. The analysis concluded the fair value of this reporting unit was less than its carrying value as of December 31, 2015, and we recorded a goodwill impairment charge of $16 million at our oil and gas reporting unit in our Technical Solutions segment in the fourth quarter of 2015. We determined that the estimated fair values of our remaining reporting units significantly exceeded their corresponding carrying values as of November 30, 2015.

May 31, 2015 Impairment Test - We continuously monitor industry events and changes in circumstances in the industries in which our reporting units conduct business. In consideration of the oil and gas reporting unit’s sensitivity to developments within its industry, the continued decline in crude oil prices, significant reductions in its customer capital spending plans, and project delays, we concluded an interim goodwill impairment test was necessary to determine whether it was more likely than not that the fair value of our oil and gas reporting unit was still higher than its carrying value as of May 31, 2015. Our assessment considered the aforementioned changes to expectations that were considered as part of our annual goodwill impairment test as of November 30, 2014. As a result of our analysis, we recorded a $59 million goodwill impairment charge at our Oil and Gas reporting unit in our Technical Solutions segment in the second quarter of 2015.

Other Intangible Assets - We perform tests for impairment of amortizable intangible assets whenever events or
circumstances suggest that amortizable intangible assets may be impaired.


December 31, 2015 Impairment Test - We performed an impairment test asDue to the many variables inherent in the estimation of December 31, 2015,the fair values of our business and the relative size of our recorded goodwill and other purchased intangible assets, differences in assumptions may have a material effect on the amortizableresults of our impairment analysis.

In connection with the recoverability test, we reevaluated the remaining useful lives of the intangible assets and determined the total undiscounted pretax cash flows generated by the reporting unit over the remaining useful life of the primary asset, customer relationships. The carrying amount of the reporting unit was greater than the total undiscounted pretax cash flows, and, as a result, the intangible assets were written down by $27 million, charged against cost of sales and service revenues within income from operations at our oil and gas reporting unit in our Technical Solutions segment.

Litigation, Commitments, and Contingencies
 
Overview - We are subject to a range of legal proceedings before various courts and administrative agencies and are periodically subject to government examinations,audits, inquiries, and investigations that arise in the ordinary course of business. Estimating liabilities and costs associated with these matters requires judgment and assessment based upon professional knowledge and the experience of management and our internal and external legal counsel. In accordance with our practices relating to accounting for contingencies, we record amounts as charges to earnings when we determine, after taking into consideration the facts and circumstances of each matter, including any settlement offers, that it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. The ultimate resolution of any such exposure may vary from earlier estimates as further facts and circumstances become known.
 
Environmental Accruals - We are subject to the environmental laws and regulations of the jurisdictions in which we conduct operations. We record a liability for the costs of expected environmental remediation obligations when we determine that it is probable we will incur such costs and the amount of the liability can be reasonably estimated. When a range of costs is possible and no amount within that range is a better estimate than another, we record the minimum amount of the range.
 
Factors that could result in changes to the assessment of probability, range of estimated costs, and environmental liability accruals include: modification of planned remedial actions, increase or decrease in the estimated time required to remediate, discovery of more extensive contamination than anticipated, results of efforts to involve other legally responsible parties, financial insolvency of other responsible parties, changes in laws and regulations or contractual obligations affecting remediation requirements, and improvements in remediation technology. Although we cannot predict whether new information gained as remediation projects progress will materially affect the accrued liability, we do not believe that future remediation expenditures will have a material effect on our financial position, results of operations, or cash flows.


Asset Retirement Obligations Income Tax Matters - We record all known asset retirement obligations for which the liability's fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning, and contractual lease restoration obligations. Recorded amounts asThe evaluation of each of December 31, 2017 and 2016, were $19 million and consist primarily of obligations associated with the wind down of shipbuilding operations at our Avondale facility. See Note 2: Summary of Significant Accounting Policiestax positions taken in Item 8.
We also have known conditional asset retirement obligations related to assets currently in use, such as certain asbestos remediation and asset decommissioning activitiesa filed tax return, or planned to be performedtaken in thea future that were not reasonably estimable as of December 31, 2017, due to insufficient information about the timing and method of settlement of the obligation. Accordingly, the fair value of these obligations has not been recorded in the consolidated financial statements. Environmental remediation and/tax return or asset decommissioning of these facilities may be required when we cease to utilize these facilities. In addition, there may be conditional environmental asset retirement obligations that we have not yet discovered (for example, asbestos of which we have not become aware through normal business operations may exist in certain buildings), and these obligations have therefore not been included in our consolidated financial statements.
Litigation Accruals - Litigation accruals are recorded as charges to earnings when management has determined, after taking into consideration the facts and circumstances of each matter, including any settlement offers, that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The ultimate resolution of any exposure may vary from earlier estimates as further facts and circumstances become known. Based upon the information available, we believe that the resolution of any of these various legal proceedings will not have a material effect on our consolidated financial position, results of operations, or cash flows.
Uncertain Tax Positions - Uncertainclaim, requires judgment. We establish reserves for uncertain tax positions meetingthat do not meet the more-likely-than-not recognition threshold, based on the merits of the position, are recognized in the financial statements.position. We recognize the amount of a tax benefit that is

greater than 50% likely to be realized upon ultimate settlement with the related tax authority. If a tax position does not meet the minimum statutory threshold to avoid payment of penalties, we recognize an expense for the amount of the penalty in the period the tax position is claimed or expected to be claimed in our tax return. Penalties and accrued interest related to uncertainunrecognized tax positionsbenefits are recognized as a component of income tax expense. See Note 13:12: Income Taxes in Item 8. Changes in accruals associated with uncertainunrecognized tax positionsbenefits are recorded in earnings in the period they are determined.


For further information on litigation, commitments, and contingencies, see Risk Factors in Item 1A and Note 2: Summary of Significant Accounting Policies, Note 4: Acquisitions and Divestitures, Note 12: Income Taxes, Note 14: Investigations, Claims, and Litigation, and Note 16: Commitments and Contingencies in Item 8.

Retirement Related Benefit Plans


We recognize, on a plan-by-plan basis, the funded status of our retirement related benefit plans as an asset or liability on our balance sheet, with corresponding adjustments to after-tax accumulated other comprehensive incomeloss and deferred tax assets or liabilities. The funded status represents the difference between the benefit obligation and the fair value of plan assets. See Note 18:17: Employee Pension and Other Postretirement Benefits in Item 8.


We calculate our retirement related benefit plan costs under both CAS and U.S. GAAP Financial Accounting Standards ("FAS"). The calculations under CAS and FAS require significant judgment. CAS prescribes the determination, allocation, and recovery of retirement related benefit plan costs on U.S. Government contracts through the pricing of products and services. FAS prescribes the methodology used to determine retirement related benefit plan expense or income, as well as the liability, for financial reporting purposes. The CAS requirements for
35


these costs and their calculation methodologies differ from FAS. As a result, while both CAS and FAS use assumptions in their calculation methodologies, each method results in different calculated amounts of retirement related benefit plan costs.


Retirement related benefit plan costs are allocated to our U.S. Government contracts as allowable costs based upon CAS. We recover our CAS costs through the pricing of products and services on U.S. Government contracts, so that the CAS cost is recognized in segment product sales and service revenues and in the costs of those product sales and service revenues. In order to present our consolidated financial statements in accordance with FAS, we record the difference between our FAS expense and CAS cost (“FAS/CAS Adjustment”) as operating income (loss) within generalsegment operating income and administrative expenses. For the years ended December 31, 2017, 2016, and 2015, our CAS costs in excess of FAS expenses were $189 million, $145 million, and $104 million, respectively.non-operating retirement benefit (expense).


The minimum funding requirements for our qualified pension plans are determined under the Employee Retirement Income Security Act of 1974 ("ERISA"), which is primarily based on the year's expected service cost and amortization of other previously unfunded liabilities. Effective January 1, 2011, we were subject to the funding requirements under the Pension Protection Act of 2006 ("PPA"), which amended ERISA. Under the PPA, we are required to fully fund our pension plans over a rolling seven-year period as determined annually based upon the funded status at the beginning of each year. PPA also introduced a variety of benefit restrictions that apply if a plan falls below certain funded percentages, as defined by the Internal Revenue Code. In funding our plans, we consider various factors, including the minimum funding requirements, maintaining the funded status needed to avoid potential benefit restrictions and other adverse consequences, maintaining minimum CAS funding requirements, and the current and anticipated funding levels of each plan.


During 2012,Effective January 1, 2021, we adopted the Safe Harbor methodology used in determining CAS pension costs. The interest rates used to calculate pension liabilities under CAS are consistent with those used in the determination of minimum funding requirements under ERISA.

Pension funding requirements under ERISA are subject to pension relief for plan sponsors in the form of higher interest rate assumptions introduced by the Moving Ahead for Progress in the 21st Century Act ("MAP-21") was enacted. MAP-21 included provisions for potential pension relief to plan sponsors inand subsequently extended by the formAmerican Rescue Plan Act of higher interest rate assumptions that were used to determine2021. Using these minimum funding requirements. The relief derived from these provisions was to be phased out to lower levels over the next few years. The enactment of the Highway and Transportation Funding Act (“HATFA”) in 2014 and BBA 2015 successively providedinterest rates for the continuationpurposes of determining pension costs under CAS reduces volatility in CAS costs year-over-year and provides more predictable costs for our customers, while better aligning reimbursements of pension relief and higher interest rate assumptions used to determine minimum funding requirements and extended thecosts under our contracts with our required pension relief phase-out period. We consider the effects of pension relief legislation in the context of current year and future projected funded status levels in deciding the level ofplan contributions to make to our plans each year.under ERISA.


Due to the differences in requirements and calculation methodologies between FAS and CAS, our FAS pension expense is not necessarily indicative of the funding requirements under PPA or the amounts we recover from the U.S. Government under CAS.


When PPA was enacted, it was anticipated that the amounts required to be funded would exceed government contractors' recovery of those costs under CAS. To remedy this cash flow misalignment, on December 27, 2011, the U.S. Cost Accounting Standards Board issued its final CAS Harmonization Rule ("Harmonization"). Harmonization

was intended to improve the alignment of the pension cost recovered through contract pricing under CAS and the pension funding requirements under the PPA. Harmonization became effective for forward pricing purposes for contracts negotiated on or after February 27, 2012. Under Harmonization, only contracts entered into before the effective date qualifed for an equitable adjustment. Price proposals for CAS covered contracts awarded on or after the effective date of February 27, 2012, reflected the effects of the rule. Harmonization affected pension costs on contracts over a phase-in period that ended in 2017. Our CAS pension cost recoveries are expected to remain unaffected by the pension relief provisions noted above because of the method permitted under Harmonization we use to determine the CAS interest rate, which is a current market rate.

Assumptions - We account for our retirement related benefit plans on the accrual basis under FAS. The measurements of obligations, costs, assets, and liabilities require significant judgment. We annually review our assumptions, which are set at each year end and are generally not changed during the following year unless there is a major plan event occurs, such as an amendment, curtailment,, or settlement that would trigger a remeasurement. The key assumptions in these measurements are the interest rate used to discount future benefit payments and the expected long-term rate of return on plan assets.


Discount Rate - The assumed discount rate under FAS is used to determine the retirement related benefit plan obligations and expense, and represents the hypothetical rate at which the plans'plan benefit obligations could be effectively settled at the measurement date. Consequently, the discount rate can be volatile from year to year. The discount rate assumption is determined for each plan by constructing a hypothetical portfolio of high qualityhigh-quality bonds with cash flows that match the estimated outflows for future benefit payments to determine a single equivalent discount rate. Benefit payments are not only contingent on the terms of a plan but also on the underlying participant demographics, including current age and assumed mortality. We use only bonds that are denominated in U.S. Dollars, are rated Aa or better by nationally recognized statistical rating agencies, have a minimum outstanding issue of $100 million as of the measurement date, and are not callable, convertible, or index-linked.


Taking into consideration the factors noted above, our weighted average discount rate for pensions was 3.82% and 4.47% as of December 31, 2017 and 2016, respectively. Our weighted average discount rate for other postretirement benefits was 3.85% and 4.38% as of December 31, 2017 and 2016, respectively.

Expected Long-Term Rate of Return - The expected long-term rate of return on assets is used to calculate net periodic expense, and is based on such factors as historical returns, targeted asset allocations, investment policy, duration, expected future long-term performance of individual asset classes, interest rates, inflation, portfolio volatility, investment management and administrative fees, and risk management strategies. Historical plan asset performance alone has inherent limitations in predicting future returns. While studies are helpful in understanding past and current trends and performance, the rate of return assumption is based more on long-term prospective
36


views to avoid short-term market influences. Unless plan assets and benefit obligations are subject to remeasurementre-measurement during the year, the expected return on pension assets is based on the fair value of plan assets at the beginning of the year. We used a 7.25% expected long-term rate of return assumption to record 2017 pension expense, and we anticipate retaining that assumption throughout 2018.


Mortality - Mortality assumptions are used to determine the retirement related benefit obligations and expense, and represent the likelihood and duration of benefit payments to plan participants based on historical experience and projected longevity.We periodically update our mortality assumptions as circumstances warrant.


Differences arising from actual experience or changes in assumptions might materially affect retirement related benefit plan obligations and the funded status. Actuarial gains and losses arising from differences between assumptions and actual experience or changes in assumptions are deferred in accumulated other comprehensive income.loss. This unrecognized amount is amortized as a component of net expense to the extent it exceeds 10% of the greater of the plan's benefit obligation or plan assets. The amortization period for actuarial gains and losses is the estimated average remaining service life of the plan participants. In 2017,2021, the actual return on assets was approximately 17.0%12.7%, which was greatermore than the expected return assumption of 7.25%. For the year ended December 31, 2017,2021, the weighted average discount rates for our pension and other postretirement benefit plans decreasedincreased by 6520 and 5319 basis points, respectively. These differences in asset returns updated mortality assumptions, and discount rates resulted in actuarial gains of $473$412 million and $68 million and an actuarial loss of $625$289 million, respectively, as offor the year ended December 31, 2017.2021.



An increase or decrease of 25 basis points in the discount rate and the expected long-term rate of return assumptions would have had the following approximate impacts on pensions:pension expense and obligations:
($ in millions)Increase (Decrease) in 2022 ExpenseIncrease (Decrease) in December 31, 2021 Obligations
25 basis point decrease in discount rate$29 $329 
25 basis point increase in discount rate(15)(310)

25 basis point increase in discount rate (22) (246)
25 basis point decrease in expected return on assets 15
 

25 basis point increase in expected return on assets (15) 



Assuming a 7.25% expected return on assetassets assumption, a $50 million pension plan contribution is generally expected to favorably impact the current year expected return on assets by approximately $1$2 million, depending on the timing of the contribution.


Sensitivities to assumptions are not necessarily linear and are specific to the time periods noted.


CAS Cost - In addition to providing the methodology for calculating retirement related benefit plan costs, CAS also prescribes the method for assigning those costs to specific periods. While the ultimate liability for such costs under FAS and CAS is similar, the pattern of cost recognition is different. The key drivers of CAS pension cost include the funded status and the method used to calculate CAS reimbursement for each of our plans. A plan’s CAS pension cost can only be allocated until the plan is fully funded as defined under the CAS requirements.


Through 2013, CAS required the pension interest rate to be consistent with the expected long-term rate of return on assets assumption, which changed infrequently given its long-term nature. As a result, short-term changes in bond yields or other interest rates generally did not impact CAS costs. Under Harmonization the liability used to determine CAS cost is developed by comparing the liability under the previous CAS methodology and assumptions to a liability based on a discount rate derived from yields on high quality corporate bonds. Since Harmonization became fully phased in during 2017, the greater of the two liabilities is used for CAS cost calculations. Generally, liabilities based on a discount rate of high quality corporate bonds will be higher than liabilities calculated prior to Harmonization. Prior to the full phasing in of Harmonization the use of a blend of the pre and post Harmonization liabilities was required.

Other FAS and CAS Pension Considerations - A key driver of the difference between FAS expense and CAS cost (and consequently the FAS/CAS Adjustment) is the pattern of earnings and expense recognition for actuarial gains and losses that arise when our asset and liability experiences differ from our assumptions under each set of requirements. Under FAS, our net actuarial gains and losses exceeding the 10% corridor are amortized over the estimated average remaining service life of the plan participants. Under CAS Harmonization, the amortization period changed from 15 tois 10 years for actuarial gains and losses beginning in 2013.losses. Both FAS and CAS use a "market-related value" of plan assets approach to calculate the amount of deferred asset gains or losses to be amortized. Under CAS, actual asset gains and losses are systematically smoothed over five years, subject to certain limitations. For FAS, we do not use this smoothing method, and instead use fair value in determining our FAS expense. Accordingly, FAS expense generally reflects recent asset gains and losses sooner than CAS.


Additionally, CAS cost is only recognized for plans that are not fully funded as defined under CAS. If a plan becomes or ceases to be fully funded due to our asset or liability experience, our CAS cost will change accordingly.


The FAS/CAS Adjustment in 2017 and 2016 was a net benefit of $189 million and $145 million, respectively. The favorable change from 2016 to 2017 was primarily driven by the continued phase-in of Harmonization. The FAS/CAS Adjustment in 2015 was a net benefit of $104 million. The favorable change from 2015 to 2016 was driven by the continued phase-in of Harmonization. Our projected 2018 FAS/CAS Adjustment is discussed in Consolidated Operating Results - Operating Income.

Retirement Plan Assets - Retirement plan assets are stated at fair value. Investments in equity securities (common and preferred) are valued at the last reported sales price when an active market exists. Investments in fixed-income
37


securities are generally valued based on market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders. Investments in hedge funds, real estate

investment funds, private partnerships, collective trust funds, and commingled funds are generally valued at their Net Asset Values ("NAV") or equivalent, which are based on the current fair valuevalues of the fund's underlying assets.


Management reviews independently appraised values, audited financial statements, and additional pricing information to evaluate the NAV or its equivalent.

For the limited group of investments for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value, additional information is obtained from the investment manager and evaluated internally to determine whether any adjustments are required to reflect fair value. See Note 18:17: Employee Pension and Other Postretirement Benefits in Item 8.


Accumulated Other Comprehensive IncomeLoss - Changes in assumptions and changes to plan assets and benefit obligations due to differences between actuarial assumptions and actual results are reported as actuarial gains and losses and recorded in accumulated other comprehensive incomeloss, along with unrecognized prior service costs arising from plan amendments. As disclosed in Note 18:17: Employee Pension and Other Postretirement Benefits in Item 8, net pre-tax unrecognized actuarial losses as of December 31, 20172021 and 20162020 were $1,459$1,194 million and $1,583$2,007 million, respectively. The decrease in these actuarial losses in 20172021 was primarily driven by actual asset returns which were $473 million aboveexceeding expected returns $93by $412 million, lower benefit obligations of $289 million resulting from higher discount rates, and $107 million of amortization of previously unrecognized actuarial losses, $68 million actuarial gain from updated mortality assumptions, and a $625 million actuarial loss due to the decrease in the discount rates used to determine benefit obligations.losses.


Net pre-tax unrecognized prior service costs (credits) as of December 31, 20172021 and 20162020 were $47$60 million and $(18)$85 million, respectively. These net deferred costs (credits) primarily originated from plan amendments, including those resulting from collective bargaining agreements. The change in unrecognized prior service costs (credits) in 2017 primarily2021 resulted from plan amendments within a collective bargaining agreement, offset byand the amortization of previously accumulated prior service costs (credits).


Workers' Compensation
 
Our operations are subject to federal and state workers' compensation laws. We maintain self-insured workers' compensation plans and participate in federally administered second injury workers' compensation funds. We estimate the liability for such claims and funding requirements on a discounted basis utilizing actuarial methods based on various assumptions, which include our historical loss experience and projected loss development factors. We periodically, and at least annually, update our assumptions based on an actuarial analysis. Related self-insurance accruals include the liability for reported claimsFor further information on workers’ compensation, see Environmental, Health & Safety in Item 1 and an estimated accrual for claims incurred but not reported. Our workers' compensation liability was discounted at 2.35%Note 16: Commitments and 2.54% as of December 31, 2017 and 2016, respectively, based on future payment streams and a risk-free rate. We estimate a 100 basis points increase or decreaseContingencies in the discount rate would change our workers' compensation liability by $(48) million and $58 million, respectively. The workers' compensation benefit obligation on an undiscounted basis was $925 million and $835 million as of December 31, 2017 and 2016, respectively.Item 8.

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 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.

Cost of product sales at our Ingalls segment increased $64$22 million in 2017,2020, primarily as a result of lower risk retirement in the San Antonio class (LPD 17) program, following delivery of USS John P. Murtha (LPD 26) in 2016, as well as the volume changes described above, partially offset by higher risk retirement on Tripoli (LHA 7).Delbert D. Black (DDG 119) in connection with its delivery and a capital expenditure contract incentive. Cost of product sales at our Newport News segment increased $56$480 million in 2017,2020, primarily as a result of program cost growth and the volume increases described above. Cost of product sales at our Technical Solutions segment increased $65 million in 2020, primarily due to the higher volumes described above. Cost of product sales related to the Operating FAS/CAS Adjustment decreased $104 million from 2019 to 2020.

Cost of product sales as a percentage of product sales decreased from 82.3% in 2019 to 82.1% in 2020, primarily due to a favorable change in the Operating FAS/CAS Adjustment and higher risk retirement on Delbert D. Black (DDG 119), USS Tripoli (LHA 7), and Richard M. McCool Jr. (LPD 29), as well as year-to-year variances in contract mix, partially offset by unfavorable cumulative catch-up adjustments in the second quarter of 2020 of $111 million on Block IV boats of the Virginia class (SSN 774) submarine program, including $95 million for cost and schedule performance and updates to our assumptions for future program efficiencies and performance as a result of cost and schedule trends, as well as $16 million from delay and disruption directly attributable to COVID-19 Events. The decrease in cost of product sales as a percentage of product sales was also offset by unfavorable cumulative catch-up adjustments in the second quarter of 2020 aggregating $61 million across all programs, resulting from cost estimates for delay and disruption from discrete COVID-19 Events, including $16 million in relation to the Block IV boats of the Virginia class (SSN 774) submarine program discussed above.

Cost of service revenues as a percentage of service revenues increased from 82.4% in 2020 to 87.1% in 2021, primarily driven by an unfavorable change in the Operating FAS/CAS Adjustment, lower risk retirement on submarine support services, and year-to-year variances in contract mix.

2020 - Cost of service revenues in 2020 decreased $140 million, or 6%, compared to 2019. Cost of service revenues at our Ingalls segment decreased $10 million in 2020, primarily as a result of the volume changes described above, and the resolution of outstanding contract changes on the RCOH of the redelivered USS Abraham Lincoln (CVN 72), partially offset by lower risk retirementrecovery of losses on a long-term design contract in the Virginia class (SSN 774) submarine program.2019.

Cost of product sales as a percentage of product sales increased from 77.8% in 2016 to 79.7% in 2017,

primarily driven by lower risk retirement in the San Antonio class (LPD 17) program, following delivery of USS John P. Murtha (LPD 26) in 2016, the Virginia class (SSN 774) submarine program, and Arleigh Burke class (DDG 51) destroyers, as well as the establishment of an allowance for accounts receivable on a nuclear and environmental commercial contract, partially offset by higher risk retirement on Tripoli (LHA 7) and the resolution of outstanding contract changes on the RCOH of the redelivered USS Abraham Lincoln (CVN 72).

2016 - Cost of product sales in 2016 increased $61 million, or 1%, compared to 2015.

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.


20172021 - Income from operating investments, net increased $6$9 million, or 100%28%, to $12$41 million in 20172021 from $6$32 million in 2016.2020. The increase resulted from higher equity income from our Savannah River Nuclear Solutions, LLC investment.ship repair and specialty fabrication joint venture and nuclear and environmental joint ventures.


2016 2020 - Income from operating investments, net decreased $4increased $10 million, or 40%45%, to $6$32 million in 20162020 from $10$22 million in 2015.2019. The decreaseincrease resulted from lowerhigher equity income from our Savannah River Nuclear Solutions, LLC investment.SRNS and MSTS investments.


Other Income and Gains, Net


20172021 - Other income and gains, decreased $15 millionnet in 20172021 were flat compared to 2016. The decrease resulted from state2020.

2020 - Other income and local government grants at our Newport News segmentgains, net in 2016.2020 were flat compared to 2019.



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.


20172021 - General and administrative expenses in 20172021 decreased $53$6 million, or 9%1%, compared to 2016.2020. This decrease was primarily driven by favorable changes in current state income tax expense, partially offset by unfavorable changes in non-current state income tax expense and higher overhead costs driven by the FAS/CAS Adjustment.acquisition of Alion.


20162020 - General and administrative expenses in 2016 decreased $462020 increased $116 million, or 7%15%, compared to 2015.2019. This decreaseincrease was primarily driven by the acquisition of Hydroid and higher overhead costs and current state income tax expense, partially offset by favorable changes in the FAS/CAS Adjustment and lower currentnon-current state income tax expense.


Goodwill Impairment of Goodwill


As discussed above underin Critical Accounting Policies, Estimates and Judgments, we perform impairment tests for
goodwill as of November 30 each year, or when evidence of potential impairment exists. We record a charge to operations when we determine that an impairment has occurred.

We recorded goodwill impairment charges in 2015 of $75 million in our Technical Solutions segment. See Note 12: Goodwill and Other Purchased Intangible Assets in Item 8.


Operating Income


We consider operating income to be an important measure for evaluating our operating performance, and, as is typical in theconsistent with industry practice, we define operating income as revenues less the related costcosts 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.

Segment Operating Income


20172021 - Segment operating income in 20172021 was $688$683 million, compared to $715$555 million in 2016.2020. The decreaseincrease was primarily duedriven by impacts related to lower risk retirementperformance on Block IV boats of the delivered USS John P. Murtha (LPD 26), lower volume and risk retirement in the Virginiaclass (SSN 774) submarine program and Arleigh Burkedelay and disruption from discrete COVID-19 Events in 2020.

2020 - Segment operating income in 2020 was $555 million, compared to $631 million in 2019. The decrease was driven by unfavorable cumulative catch-up adjustments in the second quarter of 2020 totaling $167 million from updated cost and schedule assumptions across all programs.

Included in the $167 million of unfavorable adjustments was $111 million related to Block IV boats of the Virginia class (DDG 51) destroyers, favorable changes(SSN 774) submarine program for unfavorable cost and schedule performance and updates to our assumptions for future program efficiencies and performance as a result of cost and schedule trends. Our risk retirement assumptions on Block IV boats anticipated boat-to-boat cost and schedule improvements working down the learning curve, but performance trends, exacerbated by COVID-19 Events, made those improvements less likely to occur. Also included in overhead coststhe $167 million of unfavorable adjustments was $61 million for the margin impact of delay and disruption cost estimates across all programs from discrete COVID-19 Events, including $16 million relating to Block IV boats of the Virginia class (SSN 774) submarine program, which was included in 2016, the receipt in 2016 of a local government incentive grant, and the establishment of an allowance for accounts receivable on a nuclear and environmental commercial contract in 2017,$111 million unfavorable adjustments noted above. These unfavorable margin adjustments were partially offset by higher risk retirement on USS Delbert D. Black (DDG 119) in connection with its delivery and a capital expenditure contract incentive, higher risk retirement and improved performance on USS Tripoli (LHA 7) and PortlandRichard M. McCool Jr. (LPD 27), the resolution of

outstanding contract changes on the inactivation of the decommissioned Enterprise (CVN 65) and the RCOH of the redelivered USS Abraham Lincoln (CVN 72)29), and improved performancea loss on a fleet support services contract in oil and gas services.2019.

2016 - Segment operating income in 2016 was $715 million, compared to $667 million in 2015. The increase was primarily due to the goodwill and intangible asset impairment charges in the Technical Solutions segment in 2015, higher risk retirement on the San Antonio class (LPD 17) program, favorable changes in overhead cost, and the receipt of a local government incentive grant, partially offset by the impact in 2015 of the settlement of the Aon litigation, lower risk retirement in the Virginia class (SSN 774) submarine program, and lower volume and lower risk retirement on the execution contract for the RCOH of USS Abraham Lincoln (CVN 72).


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


FAS/CAS Adjustment and Operating FAS/CAS Adjustment


The FAS/CAS Adjustment representsreflects the difference between ourexpenses for pension and other postretirement benefits determined in accordance with GAAP and the expenses for these items included in segment operating income in accordance with CAS. The Operating FAS/CAS Adjustment excludes the following components of net periodic benefit costs: interest cost, expected return on plan expenseassets, 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 for determining CAS pension costs. Under the new methodology, the interest rates used to calculate pension liabilities under FAS andCAS are consistent with those used in the determination of minimum funding requirements under CAS.the Employee Retirement Income Security Act of 1974 ("ERISA").

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

20172021 - The Operating FAS/CAS Adjustment in 20172021 was a net benefitexpense of $189$157 million, compared to a net benefit of $145$248 million in 2016.2020. The unfavorable change was primarily driven by the more immediate recognition of higher interest rates under CAS.

2020 - The Operating FAS/CAS Adjustment in 2020 was a net benefit of $248 million, compared to a net benefit of $124 million in 2019. The favorable change was primarily driven by the continued phase-inmore immediate recognition of Harmonization.lower interest rates under CAS.

2016 - The FAS/CAS Adjustment in 2016 was a net benefit of $145 million, compared to a net benefit of $104 million in 2015. The favorable change was primarily driven by the continued phase-in of Harmonization.


We expect the FAS/CAS Adjustment in 20182022 to be a net benefit of approximately $369$152 million ($91(($105) million FAS and $460$47 million CAS), primarily driven by the more immediate recognition of the 20172021 asset gainsreturns under FAS.

We expect the Operating FAS/CAS Adjustment in 2022 to be a net expense of approximately $142 million ($189 million FAS and the impacts of lower discount and interest rates and other experience gains and losses and assumption changes (e.g., mortality)$47 million CAS). The expected FAS/CAS Adjustment is subject to change during 2018,2022, when we remeasure our actuarial estimate of the unfunded benefit obligation for CAS with updated census data and other items later in the year.


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 uncertainunrecognized tax positionsbenefits 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.


20172021 - Non-current state income tax expense in 20172021 was $12$13 million, compared to $2$4 million in 2016. Deferred2020. The unfavorable change in non-current state income taxes was driven by an increase in deferred state income tax expense, primarily attributable to a decrease in expenses not currently deductible for income tax purposes.

2020 - Non-current state income tax expense in 20172020 was $12$4 million, compared to $19 million in 2019. The decrease in non-current state income tax expense was driven by a decrease in deferred state income tax expense of $8 million in 2016.expense. The increasedecrease in deferred state income tax expense was primarily attributable to changesan increase in pension related adjustments. In 2017, the decrease in state uncertain tax positions resulted in a net tax benefit of less than $1 million, compared to a tax benefit of $6 million in 2016. In 2016, a state uncertain tax position was settled through agreement with the applicable taxing authority and was partially offset by the recognition of a non-current state tax expense in a different jurisdiction impacted by the results of the settlement. See Note 13: Income Taxes in Item 8.

2016 - Non-current stateexpenses that are not currently deductible for income tax expense remained constant at $2 million in 2016 and 2015. Deferred state income tax expense in 2016 was $8 million as compared to deferred state income tax expense of less than $1 million in 2015. The increase in deferred state income tax expense was primarily attributable to changes in the timing of contract taxable incomepurposes and pension related adjustments. In 2016, the decrease in state uncertain tax positions resulted in a net tax benefit of $6 million, as compared to $2 million of tax expense in 2015. The state uncertain tax position was settled through agreement with the applicable taxing authority and was partially offset by

the recognition of a non-current state tax expense in a different jurisdiction impacted by the results of the settlement. See Note 13: Income Taxes in Item 8.


Interest Expense


20172021 - Interest expense in 20172021 was $94$89 million, compared to $74$114 million in 2016.2020. The decrease was primarily a result of costs associated with the early redemption in 2020 of $600 million aggregate principal amount of our 5.000% senior notes due in 2025, partially offset by increased borrowing to fund the acquisition of Alion with the issuance of $400 million aggregate principal amount of 0.670% senior notes due 2023, $600 million aggregate principal amount of 2.043% senior notes due 2028, and a $650 million three-year Term Loan.

2020 - Interest expense in 2020 was $114 million, compared to $70 million in 2019. The increase was primarily a result of a loss oncosts associated with the early extinguishmentredemption of debt$600 million aggregate principal amount of our 5.000% senior notes due 2025 and the issuance in 2020 of $500 million aggregate principal amount of 3.844% senior notes due 2025 and $500 million aggregate principal amount of 4.200% senior notes due 2030, partially offset by reduced borrowing on our credit facilities.

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.

2021 - A favorable change in the fourth quarternon-operating retirement benefit of 2017. See Note 14: Debt$62 million from 2020 to 2021 was primarily driven by higher 2020 returns on plan assets.

2020 - A favorable change in Item 8.the non-operating retirement benefit of $107 million from 2019 to 2020 was primarily driven by higher 2019 returns on plan assets.

Other, Net

2021 - Interest expenseOther, net income in 20162021 was $74$17 million, compared to $137$6 million in 2015.2020. The decreaseincrease was primarily driven by an impairment of a result of refinancing $600 million principal amount of 7.125% senior notesloan receivable in 2020.

2020 - Other, net income in 2020 was consistent with 5.000% senior notes and repayment in 2015 of credit facility term loans, as well as the loss on early extinguishment of debt in 2015. See Note 14: Debt in Item 8.2019.


Federal and Foreign Income Taxes


2017 2021 - Our effective tax rate on earnings from continuing operations was 38.0%12.5% in 2017,2021, compared to 26.9%14.1% in 2016.2020. The increasedecrease in our effective tax rate for 20172021 was primarily attributable to the revaluation of net deferred tax assets resulting from the decrease in the federal tax rate included in the Tax Act and a decrease in the domestic manufacturing deduction primarily resulting from an increase in research and development tax credits for prior periods and a tax loss associated with the Company’s 2018 expected discretionary pre-tax pension contributions. See Note 13: Income Taxessale of our oil and gas business, partially offset by an increase in Item 8.unrecognized tax benefits.


20162020 - Our effective tax rate on earnings from continuing operations was 26.9%14.1% in 2016,2020, compared to 36.1%19.6% in 2015.2019. The decrease in our effective tax rate for 20162020 was primarily attributable to the adoption of ASU 2016-09, which reduced incomefavorable adjustments related to research and development tax expense by the incomecredits for prior tax benefits resulting from stock award settlement activity, a re-measurement of uncertain tax positions that resulted in a decrease in cumulative unrecognized tax benefits, and the goodwill impairment that was recorded in 2015. See Note 13: Income Taxes in Item 8.years.


In December 2017, the U.S. enacted the Tax Act, which made significant changes to U.S. federal income tax law, including a reduction of the statutory federal corporate income tax rate from 35.0% to 21.0% and changes or limitations to certain deductions. As a result of the corporate income tax reduction effective January 1, 2018, we revalued our net deferred tax assets as of December 31, 2017. This reduced our net deferred tax assets by $56 million, which was recorded as additional income tax expense for the year ended December 31, 2017. In future periods, we expect that Tax Act changes will positively impact our after-tax earnings primarily due to the lower corporate income tax rate.

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.


45


Segment Operating Income


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 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 EACestimated 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
Ingalls
For the years ended December 31, 2021, 2020, and 2019, favorable and unfavorable cumulative catch-up adjustments were as follows:
Year Ended December 31
($ in millions)202120202019
Gross favorable adjustments$244 $244 $247 
Gross unfavorable adjustments(129)(273)(151)
Net adjustments$115 $(29)$96 

For the year ended December 31, 2021, favorable cumulative catch-up adjustments included risk retirement on Bougainville (LHA 8), a contract incentive on Jack H. Lucas (DDG 125) and risk retirement on Fort Lauderdale (LPD 28). During the same period, no unfavorable cumulative catch-up margin adjustments were individually significant.

For the year ended December 31, 2020, favorable cumulative catch-up adjustments included risk retirement on Delbert D. Black (DDG 119) in connection with its delivery and a capital expenditure contract incentive, naval nuclear support services, the San Antonio class (LPD 17) program, and other individually insignificant adjustments.

During the same period, unfavorable cumulative catch-up adjustments were primarily driven by $111 million in the second quarter of 2020 on the Block IV boats of the Virginia class (SSN 774) submarine program, including $95 million for cost and schedule performance and updates to our assumptions for future program efficiencies and performance as a result of cost and schedule trends. Our risk retirement assumptions on Block IV boats anticipated boat-to-boat cost and schedule improvements working down the learning curve, but performance trends, exacerbated by the COVID-19 Events, made those improvements less likely to occur. Unfavorable cumulative catch-up adjustments on the Block IV boats of the Virginia class (SSN 774) submarine program also included $16 million from delay and disruption directly attributable to COVID-19 Events due to lower employee attendance, decreased availability of critical skills, and out-of-sequence work. Unfavorable cumulative catch-up adjustments across all programs resulting from delay and disruption cost estimates for discrete COVID-19 Events were $61 million, including $16 million in relation to the Block IV boats of the Virginia class (SSN 774) submarine program discussed above.

For the year ended December 31, 2019, favorable cumulative catch-up adjustments were related to contract changes on submarine support services, risk retirement on the Legend class NSC program, surface combatants, and the RCOH of USS George Washington (CVN 73), as well as other individually insignificant adjustments. During the same period, unfavorable cumulative catch-up adjustments included recognition of a forward loss on a fleet support services contract and schedule delays on USS Tripoli (LHA 7), as well as other individually insignificant adjustments.

When estimates of total costs to be incurred exceed estimates of total revenue to be earned on a performance obligation related to a complex, construction-type contract, we recognize the entire loss on the performance obligation in the period the loss is determined.

BACKLOG


Total backlog as of December 31, 2017,2021, was approximately $21$48.5 billion. 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 Indefinite Delivery/Indefinite Quantity orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer.

We have historically maintained a capital structure comprising a mix of equity and debt financing. We vary our leverage both to optimize our equity return and to pursue acquisitions. We expect to meet our current debt obligations as they come due through internally generated funds from current levels of operations and/or through refinancing in the debt markets prior to the maturity dates of our debt.

Cash Flows


We discuss below our majorsignificant operating, investing, and financing activities affecting cash flows for each of the three years in the period ended December 31, 2017,2021, as classified in our consolidated statements of cash flows.


Operating Activities


20172021 - Cash provided by operating activities was $814$760 million in 2017,2021, compared to $822$1,093 million in 2016.2020. The decreaseunfavorable change of $8$333 million in operating cash flow was primarily due to increased funding of retiree benefit plans and the changechanges in deferred income taxes,trade working capital, partially offset by a change in trade working capital.lower income tax payments and lower contributions to retiree benefit plans. The change in trade working capital was primarily driven by the timing of payments of accounts payable.payable and receipts of accounts receivable.


We expect cash generated from operations in 2018,2022, in combination with our current cash and cash equivalents, as well as existing creditborrowing facilities, to be sufficient to service debt and retiree benefit plans, meet contractual obligations, and financefund capital expenditures for at least the next 12 months.calendar months beginning January 1, 2022 and beyond such 12-month period based on our current business plans.


20162020 - Cash provided by operating activities was $822$1,093 million in 2016,2020, compared to $861$896 million in 2015.2019.

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, analysisnet earnings as a measure of our resultsperformance or net cash provided by operating activities as reported under GAAP.a measure of our liquidity. 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.

Retirement Related Benefit Plan Contributions


ERISA, including amendments under pension relief, defines the minimum amount that must be contributed to our qualified defined benefit pension plans. In determining whether to make discretionary contributions to these plans above the minimum required amounts, we consider various factors, including maintaining the funded status needed to avoid potential benefit restrictions and other adverse consequences, maintaining minimum CAS funding requirements, and the current and anticipated future funding levels of each plan. The contributions to our qualified defined benefit pension plans are affected by a number of factors, including published IRS interest rates, the actual return on plan assets, actuarial assumptions, and demographic experience. These factors and our resulting contributions also impact the plans' funded statuses.status of the plans. We made the following minimum and discretionary contributions to our pension and other postretirement benefit plans in the years ended December 31, 2017, 20162021, 2020, and 2015:2019:

We made discretionary contributions to our qualified defined benefit pension plans totaling $294$60 million, $167$205 million, and $99$21 million in the years ended December 31, 2017, 2016,2021, 2020, and 2015,2019, respectively.


As of December 31, 20172021 and 2016,2020, our qualified pension plans were funded 89%102% and 83%91%, respectively, on a FAS basis. As of December 31, 20172021 and 2016,2020, these plans were sufficiently funded on an ERISA basis so as not to be subject to benefit payment restrictions. The funded percentages under ERISA and FAS vary due to inherent differences in the assumptions and methodologies used to calculate the respective obligations. We expect our 20182022 cash contributions to our qualified defined benefit pension plans to be $508less than $1 million, all of which we anticipate will be discretionary and which are exclusive of CAS cost recoveries inunder our contracts. Due to the differences in calculation methodologies, our FAS expense is not necessarily representative of our funding requirements or CAS cost recoveries.


Other postretirement benefit plan contributions were $34$37 million, $32$33 million, and $33$31 million in 2017, 2016,2021, 2020, and 2015,2019, respectively. We expect our 20182022 contributions to our other postretirement benefit plans to be approximately $35$34 million, which are exclusive of CAS cost recoveries inunder our contracts. Contributions for other postretirement benefitsbenefit plans are not required to be funded in advance and are paid on an as-incurred basis.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the shareholdersShareholders and the Board of Directors of
Huntington Ingalls Industries, Inc.
Newport News, Virginia



Opinion on the Financial Statements


We have audited the accompanying consolidated balance sheetsstatements of financial position of Huntington Ingalls Industries, Inc. and subsidiaries (the “Company”) as of December 31, 20172021 and 2016,2020, the related consolidated statements of operations and comprehensive income, (loss), changes in equity, and cash flows for each of the three years in the period ended December 31, 2017,2021, the related notes and the financial statement schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172021 and 2016,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2021, in conformity with the accounting principles generally accepted in the United States of America.


We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 15, 2018,10, 2022, expressed an unqualified opinion on the Company's internal control over financial reporting.


Basis for Opinion


These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.


We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.


Critical Audit Matter


The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue – Long Term Contracts — Refer to Note 2 to the financial statements

Critical Audit Matter Description
The Company recognizes revenue on long-term contracts with U.S. Government customers over time as the work progresses, either as products are produced or as services are rendered, because transfer of control to the customer is continuous. Ordinarily the Company’s contracts represent a single distinct performance obligation due to the highly interdependent and interrelated nature of the underlying goods, services, or both. The use of the cost-to-cost method to measure performance progress over time is supported by clauses in the related contracts that
57


allow the customer to unilaterally terminate the contract for convenience, pay the Company for costs incurred plus a reasonable profit, and take control of any work in process. The accounting for these contracts involves judgment, particularly as it relates to the process of estimating total material costs, labor costs, and profit for the performance obligation. Cost of sales is recognized as incurred, and revenues are determined by adding a proportionate amount of the estimated profit to the amount reported as cost of sales. For the year ended December 31, 2021, revenue was $9.5 billion, most of which was derived from long-term contracts.

Given the judgments necessary to estimate total material costs, labor costs, and profit in order to recognize revenue for certain long-term contracts, auditing such estimates required extensive audit effort due to the complexity of long-term contracts and a high degree of auditor judgment, especially given the limited historical data for certain contracts, when performing audit procedures and evaluating the results of those procedures.

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to management’s estimates of total material costs, labor costs, and profit in order to recognize revenue for certain long-term contracts included the following, among others:
We tested the effectiveness of controls over long-term contract revenue, including management’s controls over the estimates of total material costs, labor costs, and profit for performance obligations.
We developed independent estimates of revenue based on historical profit margins and current year recorded costs. We compared those estimates to revenue recognized by the Company.
We obtained the population of active contracts during 2021 and assessed the financial and performance risk of the contracts based on our knowledge gained through prior year audits of the Company, industry experience, and ongoing conversations with members of program management regarding the contract performance to identify contracts that we believe were riskier. For those contracts selected, we performed further audit procedures that were tailored to address the specific characteristics of audit interest identified. Procedures performed, among others, included:
Read the relevant portions of contracts to understand contract terms, including incentives, fee arrangement, scope of work, and other unusual contract terms.
Compared the transaction prices to the consideration expected to be received based on current rights and obligations under the contracts and any modifications that were agreed upon with the customers.
Tested management’s identification of distinct performance obligations by evaluating whether the underlying goods, services, or both were highly interdependent and interrelated.
Tested the accuracy and completeness of the costs incurred to date for the performance obligation.
Evaluated the estimates of total materials costs, labor costs, and profit for the performance obligation by:
Evaluating management’s ability to achieve the estimates of total material costs, labor costs and profit by 1) performing inquiries with the business managers and corroborating the information gained from these inquiries with other parties who have detailed knowledge of the contract’s progress, issues being encountered, and overall production status, 2) considering management’s historical performance against estimates, 3) detail testing the appropriateness of the timing of changes in estimates, and 4) considering any contradictory information.
Comparing materials cost estimates to purchase orders, supplier contracts, or other source documents.
Comparing management’s estimates for the selected contracts to costs and profits of similar performance obligations, when applicable.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the shareholdersShareholders and the Board of Directors of
Huntington Ingalls Industries, Inc.
Newport News, Virginia


Opinion on Internal Control over Financial Reporting


We have audited the internal control over financial reporting of Huntington Ingalls Industries, Inc. and subsidiaries (the "Company") as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.


We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2017,2021, of the Company and our report dated February 15, 2018,10, 2022, expressed an unqualified opinion on those financial statements.


As described in Management’s Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Alion, which was acquired on August 19, 2021, and whose financial statements constitute 5% of total assets, 5% of revenues, and 2% of net income of the consolidated financial statement amounts as of and for the year ended December 31, 2021. Accordingly, our audit did not include the internal control over financial reporting at Alion.

Basis for Opinion


The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.


We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.


Definition and Limitations of Internal Control over Financial Reporting


A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


Principles of Consolidation - The 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-K 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.


Accounting Estimates - The preparation of the Company's 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.


The Bipartisan Budget ActAdditionally, the Company has incorporated realized and estimated future effects of 2015 established limitsthe global outbreak of coronavirus disease 2019 (“COVID-19”), including, among other things, impacts from 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. For the year ended December 31, 2020, the Company recognized across all programs an aggregate unfavorable impact on operating margin of $61 million for delay and disruption from lower employee attendance, limited availability of critical skills, and out-of-sequence work directly attributable to COVID-19 Events. While costs related to COVID-19 Events are allowable under U.S. Government discretionary spending, including defense spending,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 provided sequestration relief for 2016Economic Security Act (the "CARES Act") and 2017. Sequestration remains in effect for 2018 throughU.S. Department of Defense ("DoD") guidance. For the year ended December 31, 2021, and could result in significant decreases in DoD spending that could negativelythe Company did not have a material impact on its operating margin directly attributable to COVID-19 Events.

Revenue Recognition - Most of the Company's revenues and its estimated recovery of goodwill and other long-lived assets.

Revenue Recognition - The majority of the Company's business isare derived from long-term contracts for the construction of naval vessels, production of goods and provisionservices provided to its U.S. Government customers. The Company generally recognizes revenues on contracts with U.S. Government customers over time using a cost-to-cost measure of services, primarilyprogress. The use of the cost-to-cost method to measure performance progress over time is supported by clauses in the U.S. Government. In accountingrelated contracts that allow the customer to unilaterally terminate the contract for these contracts,convenience, pay the Company extensivelyfor costs incurred plus a reasonable profit, and take control of any work in process. The Company utilizes the cost-to-cost method to
65


measure performance progress, because it best reflects the continuous transfer of control over the related goods and services to the customer as the Company satisfies its performance obligations.

When the customer is not a U.S. Government entity, the Company may recognize revenue over time or at a point in time when control transfers upon delivery, depending upon the facts and circumstances of the related arrangement. When the Company determines that revenue should be recognized over time, the Company utilizes a measure of progress that best depicts the percentage-of-completiontransfer of control of the relevant goods and services to the customer. Generally, the terms and conditions of the contracts result in a transfer of control over the related goods and services as the Company satisfies its performance obligations. Accordingly, the Company recognizes revenue over time using the cost-to-cost method to measure performance progress. The Company may, however, utilize a measure of accounting, primarilyprogress other than cost-to-cost, such as a labor-based measure of progress, if the terms and conditions of the arrangement require such accounting.

When using the cost-to-cost method to measure performance progress, certain contracts may include costs that are not representative of performance progress, such as large upfront purchases of uninstalled materials, unexpected waste, or inefficiencies. In these cases, the Company adjusts its measure of progress to exclude such costs, with the goal of better reflecting the transfer of control over the related goods or services to the customer and recognizing revenue only to the extent of the costs incurred that reflect the Company's performance under the contract.

In addition, for time and material arrangements, 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.

A performance obligation is a promise to transfer a distinct good or service to the customer and is the unit of account for which revenue is recognized. To determine the proper revenue recognition method, consideration is given to whether two or more contracts should be combined and accounted for as one contract and whether a single contract consists of more than one performance obligation. For contracts with multiple performance obligations, the contract transaction price is allocated to each performance obligation using an estimate of the standalone selling price based upon total costs incurred. Under this method, sales, including estimated earned fees or profits,expected cost plus a margin at contract inception, which is generally the price disclosed in the contract. Contracts are recordedoften modified to account for changes in contract specifications and requirements. 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 costsan adjustment to revenue on a cumulative catch-up basis. Alternatively, in instances in which the performance obligations in the modifications are incurred, generally based on the percentage that total costs incurred bear to total estimated costs at completion. Certain contracts contain provisionsdeemed distinct, contract modifications are accounted for price redetermination or for cost and/or performance incentives. Such redetermined amounts or incentives are included in sales when the amounts can reasonably be determined and estimated. Amounts representing contract change orders, claims, requests for equitable adjustment, or limitations in funding are included in sales only when they can be reliably estimated and realization is probable. prospectively.

The Company estimates profitamount of revenue recognized as the difference between total estimated revenuesCompany satisfies performance obligations associated with contracts with customers is based upon the determination of transaction price. Transaction price reflects the amount of consideration to which the Company expects to be entitled for performance under the terms and total estimated costconditions of athe relevant contract and recognizes that profit overmay reflect fixed and variable components, including shareline incentive fees whereby the lifevalue of the contract is variable based on progress toward completion. Ifupon the amount of costs incurred, as well as other incentive fees based upon achievement of contractual schedule commitments or other specified criteria in the contract. Shareline incentive fees are determined based upon the formula under the relevant contract using the Company’s estimated cost to complete for each period. The Company generally utilizes a most likely amount approach to estimate variable consideration. In all such instances, the estimated revenues represent those amounts for which the Company believes a significant reversal of revenue is not probable.

Contract Estimates - In estimating contract costs, the Company utilizes a profit-booking rate based upon performance expectations that takes into consideration a number of assumptions and estimates aregarding risks related to technical requirements, feasibility, schedule, and contract will resultcosts. Management performs periodic reviews of the contracts to evaluate the underlying risks, which may increase the profit-booking rate as the Company is able to mitigate and retire such risks. Conversely, if the Company is not able to retire these risks, cost estimates may increase, resulting in a loss,lower profit-booking rate.

The cost estimation process requires significant judgment based upon the full amountprofessional knowledge and experience of the estimated loss is recognized against incomeCompany’s engineers, program managers, and financial professionals. Factors considered in estimating the work to be completed and ultimate contract recovery include the availability, productivity, and cost of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability of
66


materials, the effect of any performance delays, the availability and timing of funding from the customer, and the recoverability of any claims included in the period in which the loss is identified.estimates to complete.



The Company classifies contract revenues as product sales or service revenues depending upon the predominant attributes of the relevant underlying contracts. The Company recognizes changesChanges in estimates of contract sales, costs, and profits on a performance obligation are recognized using the cumulative catch-up method of accounting. This methodaccounting, which recognizes in the current period the cumulative effect of the changes onin current and prior periods. Accordingly, theA significant change in an estimate on one or more contracts in a period could have a material effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate.For the years ended December 31, 2017, 2016, and 2015, net cumulative catch-up adjustments increased operating income by $204 million, $224 million, and $239 million, respectively, and increased diluted earnings per share by $2.90, $3.08, and $3.21, respectively. Cumulative catch-up adjustments for the year ended December 31, 2016, included favorable adjustments of $74 million on a contract at the Ingalls segment, which increased diluted earnings per share by $1.02. No individual adjustment was material to the Company's consolidated statementsfinancial position or results of operations and comprehensive income (loss)for that period.

When estimates of total costs to be incurred exceed estimates of total revenue to be earned on a performance obligation related to a complex, construction-type contract, a provision for the years ended December 31, 2017entire loss on the performance obligation is recognized in the period the loss is determined.

Accounts Receivable - Accounts receivable include amounts related to any unconditional Company right to receive consideration and 2015.

For services contracts not associatedare presented as receivables in the consolidated statement of financial position, separate from other contract balances. Accounts receivable are comprised of amounts billed and currently due from customers. The Company reports accounts receivable net of an allowance for doubtful accounts. Because the Company's accounts receivable are primarily with the design, development, manufacture,U.S. Government or modificationwith companies acting as a contractor to the U.S. Government, the Company does not have material exposure to accounts receivable credit risk.

Contract Assets - Contract assets primarily relate to the Company’s rights to consideration for work completed but not billed as of complex equipment,the reporting date when the right to payment is not just subject to the passage of time, including retention amounts. Contract assets are classified as current assets and, in accordance with industry practice, include amounts that may be billed and collected beyond one year due to the long-term nature of many of the Company's contracts. Contract assets are transferred to accounts receivable when the right to consideration becomes unconditional.

Contract Liabilities - Contract liabilities are comprised of advance payments, billings in excess of revenues, and deferred revenue amounts. Such advances are generally not considered a significant financing component, because they are utilized to pay for contract costs within a one-year period. Contract liability amounts are recognized upon deliveryas revenue once the requisite performance progress has occurred.

Inventoried Costs - Inventoried costs primarily relate to company-owned raw materials, which are stated at the lower of cost or as services are rendered once persuasive evidencenet realizable value, generally using the average-cost method, and costs capitalized pursuant to applicable provisions of an arrangement exists, the price is fixedFederal Acquisition Regulation ("FAR") and U.S. Cost Accounting Standards ("CAS"). Under the Company's U.S. Government contracts, the customer asserts title to, or determinable, and collectibility is reasonably assured. Costsa security interest in, inventories related to thesesuch contracts as a result of contract advances, performance-based payments, and progress payments. In accordance with industry practice, inventoried costs are expensedclassified as incurred.current assets and include amounts related to contracts having production cycles longer than one year.


Warranty Costs - Certain of the Company’s contracts contain assurance-type warranty provisions, which generally promise that the service or vessel will comply with agreed upon specifications. In such instances, the Company accrues the estimated loss by a charge to income in the relevant period. In limited circumstances, the Company's complex construction type contracts may provide the customer with an option to purchase a warranty or provide an extended assurance service coupled with the primary assurance warranty. In such cases, the Company accounts for the warranty as a separate performance obligation to the extent it is material within the context of the contract. Warranty liabilities are reported within other current liabilities and are not material.

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 yearyears ended December 31, 2017,2021, 2020, and 2019, the Company recognized cash grant benefits of approximately $21$20 million, $17 million, and $94 million, respectively, in other long-term liabilities in the consolidated statements of financial position. For the year ended December 31, 2016, the Company recognized grant benefits of approximately $30 million in depreciable assets. The Company recognized approximately $15 million in other income and gains within the consolidated statements of operations and comprehensive income (loss), and approximately $15 million in grant benefits in other long-term liabilities in the consolidated statements of financial position. For the year ended December 31, 2015, the Company recognized no grant benefits.

67



General and Administrative Expenses - In accordance with industry practice and regulations that govern the cost accounting requirements for government contracts, most general corporate expenses incurred at both the segment and corporate locations are 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 as an element of cost.


General and administrative expenses also include certain other costs that do not affect segment operating income, primarily consisting of the FAS/CAS Adjustment and the provision for non-current state income taxes. The FAS/CAS Adjustment reflects the difference between pension and postretirement benefits expenses determined in accordance with U.S. Financial Accounting Standards ("FAS") and pension and postretirement benefit expenses allocated to individual contracts in accordance with U.S. Cost Accounting Standards ("CAS"). 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 uncertainunrecognized tax positionsbenefits in the relevant period.


Research and Development - Company-sponsored research and development activities primarily include independent research and development ("IR&D") related to experimentation, design, development, and test activities for government programs. IR&D expenses are included in general and administrative expenses and are generally allocable to government contracts. Company-sponsored IR&D expenses totaled $17$34 million, $19$31 million, and $19$23 million for the years endedDecember 31, 2017, 2016,2021, 2020, and 2015,2019, respectively. Expenses for research and development sponsored by the customer are charged directly to the related contracts.


Product Warranty Costs - The Company provides certain product warranties that require repair or replacement of non-conforming items for a specified period of time often subject to a specified monetary coverage limit. The Company's product warranties are provided under government contracts, the costs of which are immaterial and are included in contract costs for purposes of using the percentage-of-completion method of accounting.


Environmental Costs - Environmental liabilities are accrued when the Company determines remediation costs are probable and such amountscosts are reasonably estimable. When only a range of amountscosts is established and no amount within the range is more probable than another, the minimum amount in the range is recorded.accrued. Environmental liabilities are recorded on an undiscounted basis and are not material. Environmental expenditures are expensed or capitalized as appropriate. Capitalized expenditures, if any, relate to long-lived improvements in currently operating facilities. The Company does not record insurance recoveries before collection is probable and, asprobable. As of December 31, 20172021 and 2016,2020, the Company did not have any accrued receivables related to insurance reimbursements or recoveries for environmental matters.


Fair Value of Financial Instruments - The accounting standard for fair value measurements provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The accounting standard provides a fair value hierarchy, which requires an entity to maximize the use of observable inputs, where available. The three levels of inputs consist of:


Level 1:Quoted prices in active markets for identical assets and liabilities.

Level 1:    Quoted prices in active markets for identical assets and liabilities.
Level 2:Observable inputs, other than Level 1 prices, such as: quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or that the Company corroborates with observable market data for substantially the full term of the related assets or liabilities.


Level 3:Unobservable inputs supported by little or no market activity that are significant to the fair value of the assets and liabilities.

Level 2:    Observable inputs, other than Level 1 prices, such as: quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or that the Company corroborates with observable market data for substantially the full term of the related assets or liabilities.

Level 3:    Unobservable inputs supported by little or no market activity that are significant to the fair value of the assets and liabilities.

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 $94$220 million and $82$182 million as of December 31, 20172021 and 2016,2020, respectively, and are presented within miscellaneous other assets within the consolidated statements of financial position. These trusts consist primarily of available-for-sale investments in marketable securities, which are held at fair value within Level 1 of the fair value hierarchy.


Foreign Currency Translation - The Company's international subsidiaries that do not have the U.S. dollar as their functional currency translate assets and liabilities at current rates of exchange in effect at the balance sheet date. Revenues and expenses from these international subsidiaries are translated using the monthly average exchange rates in effect for the periods in which the items occur. The cumulative foreign currency translation gains and losses are included as a component of accumulated other comprehensive income (loss)loss in stockholders’ equity. Gains and losses from foreign currency transactions are included in other income (expense) in the consolidated statements of operations and comprehensive income (loss).income. Such amounts are not material.
68


Asset Retirement Obligations - Environmental remediation and/or asset decommissioning may be required when the Company ceases to utilize certain facilities. The Company records, within other current liabilities or other long-term liabilities as appropriate, all known asset retirement obligations for which the liability's fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning, and lease restoration obligations.

The changes in Asset retirement obligations for which the asset retirement obligation carrying amounts for the years ended liability's fair value can be reasonably estimated were immaterial as of December 31, 2017, 2016,2021 and 2015, were as follows:2020.

($ in millions) Asset Retirement Obligations
Balance as of December 31, 2014 $22
Liabilities settled (4)
Revision of estimate (1)
Accretion expense 1
Balance as of December 31, 2015 18
Accretion expense 1
Balance as of December 31, 2016 19
Liabilities settled (1)
Accretion expense 1
Balance as of December 31, 2017 $19

The Company also has known conditional asset retirement obligations related to assets currently in use, including certain asbestos remediation and asset decommissioning activities to be performed in the future, that were not reasonably estimable as of December 31, 2017,2021, due to insufficient information about the timing and method of settlement of the obligation. Accordingly, the fair value of these obligations has not been recorded in the consolidated financial statements. A liability for these obligations is recorded in the period in which sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability's fair value. In addition, there may be conditional environmental asset retirement obligations that the Company has not yet discovered.


Income Taxes - Income tax expense and other related information are based on the prevailing statutory rates for U.S. federal income taxes and the composite state income tax rate for the Company for each period presented. 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 uncertainunrecognized tax positionsbenefits in the relevant period. These amounts are recorded within operating income, while the current period state income tax expense, which is generally considered allowable and allocable to contracts, is charged to contract costs and included in cost of sales and service revenues in segment operating income.


Deferred income taxes are recorded when revenues and expenses are recognized in different periods for financial statement purposes and for tax return purposes. Deferred tax asset or liability account balances are calculated at the balance sheet date using current tax laws and rates expected to be in effect when the deferred tax items reverse in future periods. As a result of the reduction in the corporate income tax rate from 35% to 21% effective January 1, 2018, under the Tax Cuts and Jobs Act (the "Tax Act"), the Company revalued its net deferred tax assets as of December 31, 2017. This reduced the Company's net deferred tax assets by $56 million, which was recorded as additional income tax expense for the year ended December 31, 2017.


The Company recognizes deferred tax assets to the extent it believes these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. Based on the Company's evaluation of these deferred tax assets, valuation allowances of $12 million and $11$22 million were deemed necessaryrecognized as of each of December 31, 20172021 and 2016, respectively.2020.


Uncertain tax positions meeting the more-likely-than-not recognition threshold, based on the merits of the position, are recognized in the financial statements. The Company recognizes the amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority. If a tax position does not meet the minimum statutory threshold to avoid payment of penalties, the Company recognizes an expense for the amount of the penalty in the period the tax position is claimed or expected to be claimed in its tax return. Penalties and accrued interest related to uncertainunrecognized tax positionsbenefits are recognized as a component of income tax expense. Changes in accruals associated with uncertainunrecognized tax positionsbenefits are recorded in earnings in the period in which they are determined.


Cash and Cash Equivalents - The carrying amounts of cash and cash equivalents approximate fair value due to the short-term nature of these assets, which have original maturity dates of 90 days or less.


Concentration Risk - The Company’s assets that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash and cash equivalents with reputable financial institutions and limits the amount of credit exposure with any one of them. The Company regularly evaluates the creditworthiness of these financial institutions and minimizes this credit risk by entering into transactions with high-quality counterparties, limiting the exposure to each counterparty, and monitoring the financial condition of its counterparties.


In connection with its U.S. Government contracts, the Company is required to procure certain raw materials, components, and parts from supply sources approved by the U.S. Government. Only one supplier may exist for certain components and parts required to manufacture the Company's products.


Accounts Receivable - Accounts receivable include amounts billed and currently due from customers, amounts currently due but unbilled, certain estimated contract change amounts, claims or requests for equitable adjustment in negotiation that are probable of recovery, and amounts retained by the customer pending contract completion.
69



Inventoried Costs - Inventoried costs primarily relate to production costs of contracts in process and company owned raw materials, which are stated at the lower of cost or net realizable value, generally using the average cost method. Under the Company's U.S. Government contracts, the customer asserts title to, or a security interest in, inventories related to such contracts as a result of contract advances, performance-based payments, and progress payments. In accordance with industry practice, inventoried costs are classified as a current asset and include amounts related to contracts having production cycles longer than one year. Inventoried costs also include work in process under contracts that recognize revenues using labor dollars as the basis of the percentage-of-completion calculation. These costs represent accumulated contract costs less cost of sales as calculated using the percentage-of-completion method, not in excess of recoverable value.

Advance Payments and Billings in Excess of Revenues - Payments received in excess of inventoried costs and revenues are recorded as advance payment liabilities.

Property, Plant, and Equipment - Depreciable properties owned by the Company are recorded at cost and depreciated over the estimated useful lives of individual assets. Major improvements are capitalized while expenditures for maintenance, repairs, and minor improvements are expensed. Costs incurred for computer software developed or obtainedpurchased for internal use are capitalized and amortized over the expected useful life of the software, not to exceed nine years. Leasehold improvements are amortized over the shorter of their useful lives or the term of the lease.


The remaining assets are depreciated using the straight-line method, with the following lives:
Years
Land improvements2-40
Buildings and improvements2-60
Capitalized software costs3-9
Machinery and other equipment2-40
  Years
Land improvements 2 - 40
Buildings and improvements 2 - 60
Capitalized software costs 2 - 9
Machinery and other equipment 2 - 45


The Company evaluates the recoverability of its property, plant, and equipment when there are changes in economic circumstances or business objectives that indicate the carrying value may not be recoverable. The Company's evaluations include estimated future cash flows, profitability, and other factors affecting fair value. As these assumptions and estimates may change over time, it may or may not be necessary to record impairment charges.


Leases - The Company uses its incremental borrowingdetermines if an arrangement is a lease at contract inception. A lease exists when a contract conveys to a party the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. The Company recognizes a lease liability at the lease commencement date, as the present value of future lease payments, using an estimated rate of interest that the Company would pay to borrow equivalent funds over an equivalent term on a collateralized basis. A lease asset is recognized based on the lease liability value and adjusted for any prepaid lease payments, initial direct costs, or lease incentive amounts. The lease term at the commencement date includes any renewal options or termination options when it is reasonably certain that the Company will exercise or not exercise those options, respectively.

Right of use assets associated with operating leases are recognized in operating lease assets in the assessmentconsolidated statements of financial position. Lease liabilities associated with operating leases are recognized in long-term operating lease classification as capital orliabilities, with short-term lease liability amounts included in other current liabilities in the consolidated statements of financial position.

Rent expense for operating and defines the initial lease term to include renewal options determined to be reasonably assured. The Company conducts operations primarily under operating leases.


Many of the Company's real property lease agreements contain incentives for tenant improvements, rent holidays, or rent escalation clauses. For incentives for tenant improvements, the Company records a deferred rent liability and amortizes the deferred rent over the term of the lease as a reduction to rent expense. For rent holidays and rent escalation clauses during the lease term, the Company records minimum rental expensesleases is recognized on a straight-line basis over the lease term and included in cost of sales and service revenues in the consolidated statements of operations and comprehensive income.

Goodwill and Other Intangible Assets - The Company performs impairment tests for goodwill as of November 30 of each year and between annual impairment tests if evidence of potential impairment exists, by comparing the carrying value of net assets to the fair value of the reporting unit. If the fair value is determined to be less than the carrying value, the Company records an impairment charge to the reporting unit. Purchased intangible assets are amortized on a straight-line basis or a method based on the pattern of benefits over their estimated useful lives, and the carrying value of these assets is reviewed for impairment when events indicate that a potential impairment may have occurred.

The receivable was carried at amortized cost of $36 million, net of $13 million of loan discount, as of December 31, 2021, and at amortized cost of $34 million, net of $15 million loan discount, as of December 31, 2020. The loan receivable approximates fair value and is recorded in miscellaneous other assets on the consolidated statements of financial position.

employees attain full eligibility. The discount rate assumption is defined under GAAP as the rate at which a plan's obligation could be effectively settled. The discount rate is established for each of the retirement related benefit plans at its respective measurement date.


The expected return on plan assets component of retirement related costs is used to calculate net periodic expense. Unless plan assets and benefit obligations are subject to remeasurementre-measurement during the year, the expected return on assets is based on the fair value of plan assets at the beginning of the year. The costs of plan amendments that

provide benefits already earned by plan participants (prior service costs and credits) are deferred in accumulated other comprehensive incomeloss and amortized over the expected future service period of active participants as of the date of amendment. Actuarial gains and losses arising from differences between assumptions and actual experience or changes in assumptions are deferred in accumulated other comprehensive income.loss. This unrecognized amount is amortized to the extent it exceeds 10% of the greater of the plan's benefit obligation or plan assets. The amortization period for actuarial gains and losses is the estimated remaining service life of the plan participants. 


The Company recognizes the funded status of each retirement related benefit plan as an asset or liability in its consolidated statements of financial position. The funded status represents the difference between the plan's benefit obligation and the fair value of the plan's assets. Unrecognized deferred amounts, such as demographic or asset gains or losses and the impacts of plan amendments, are included in accumulated other comprehensive incomeloss and amortized as described above.


Stock Compensation - Stock-based compensation value is determined based on the closing market price of the Company's common stock on grant date, and the expense is recognized over the vesting period. At each reporting date, the number of shares is adjusted to equal the number ultimately expected to vest based on the Company's expectations regarding the relevant performance and service criteria.

3. ACCOUNTING STANDARDS UPDATES


In May 2014,August 2018, the Financial Accounting Standards Board ("FASB") issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans, which reduces disclosure requirements of Subtopic 715-20 and requires additional disclosure related to weighted-average interest crediting rates and significant gains and losses related to changes in the benefit obligation for the reporting period. The update was effective on a retrospective basis for fiscal years ending after December 15, 2020, with early adoption allowed. The adoption did not result in a material impact to the Company's financial results or disclosures.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting Standards Update ("ASU"for Income Taxes, which amends and simplifies the requirements for income taxes. The ASU was 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.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional exceptions to GAAP for certain transactions related to the transition away from The London Interbank Offered Rate (“LIBOR”). The amended guidance is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements (e.g., loans, debt securities, derivatives, borrowings) necessitated by the reference rate reform. It also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by the reference rate reform. Application of the guidance in the amendment is optional, is only available in certain situations, and is only available for companies to apply until December 31, 2022. The Company is currently evaluating the impacts of reference rate reform and the new guidance on its consolidated financial statements.

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). The update requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASU 2014-09, “RevenueRevenue from Contracts with Customers (Topic 606)”, which. Generally, this new guidance will replace existing requirementsresult in U.S. GAAP, including industry-specific requirements, significantly expand the disclosure requirements,acquirer recognizing contract assets and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognizedcontract liabilities at the date of initial application. In July 2015,same amounts recorded by the FASB approvedacquiree. Historically, such amounts were recognized by the deferral of the new standard's effective date by one year.acquirer at fair value in accordance with acquisition accounting. The new standard is effective for annual reporting periods beginning after December 15, 2017. The FASB permitted companies to adopt the new standard early, but not before the original effective date of annual reporting periods beginning after December 15, 2016.

As part of the Company's corporate governance structure, the Company established an implementation team comprised of key stakeholders across the Company's businesses. The Company developed a plan to identify and implement applicable changes to its business processes, systems, and controls. These changes are necessary to support recognition and disclosure under the new standard. In the first quarter of 2017, the Company reached a point in its assessment to support a transition decision based on information obtained to date. Based on its

evaluation, the Company will adopt the requirements of the new standard in the first quarter of 2018 utilizing the modified retrospective method. As a result, the Company will present the cumulative effect of applying the standard at the date of initial application, January 1, 2018.

The Company has completed its evaluation of the impact of the accounting and disclosure changes on its business processes, controls, and systems and, as a result, has redefined its accounting policies affected by this standard and enhanced internal controls over financial reporting related to the standard.  The assessment of the majority of the Company's contracts under the new standard supports the recognition of revenue over time using the cost-to-cost measurement under the percentage of completion method, which is consistent with the Company's current revenue recognition practices. As such, the revenue on the majority of the Company's contracts will continue to be recognized over time considering the continuous transfer of control to the customer. Under U.S. Government contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay the Company for costs incurred plus a reasonable profit, and take control of any work in process. ASU 2014-09 also requires expanded disclosures regarding the nature, timing, and uncertainty of revenue and customer contract balances, including how and when the Company satisfies its performance obligations and the relationship between revenue recognized and changes in contract balances during a reporting period. The Company has evaluated these disclosure requirements and is incorporating the collection of relevant data into its business processes. The Company does not expect the new standard to have a material effect on its consolidated financial position, results of operations, or cash flows.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, which establishes a right-of-use model that requires a lessee to record the right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations and comprehensive income. This guidance is effective for fiscal years beginning after December 15, 2018,2022, including interim periods within those reporting periods. Earlyfiscal years, with early adoption is permitted and should be applied using a modified retrospective approach.permitted. The Company isearly adopted this standard in the process of evaluating the potential impacts of ASU 2016-02 on its consolidated financial statementsfiscal year 2021, and disclosures, contracting and accounting processes, internal controls, and information technology systems.

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”, which eliminates the performance of Step 2 from the goodwill impairment test. In performing its annual or interim impairment testing, an entity will instead compare the fair value of the reporting unit with its carrying amount and recognize any impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The Company elected to adopt ASU 2017-04 as of November 30, 2017. The adoption of ASU 2017-04it did not have a material impact on the Company's consolidated financial statements and disclosures, accounting processes, or internal controls.statements.


In March 2017,November 2021, the FASB issued ASU 2017-07, “Retirement Benefits2021-10, Government Assistance (Topic 715): Improving832), which requires business entities to disclose information about transactions with a government that are accounted for by applying a grant or contribution model by analogy (“ASU 2021-10”). For transactions within scope, the Presentationnew standard requires the
72


disclosure of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. The update requires employers to presentinformation about the service cost componentnature of the net periodic benefit cost intransaction, including significant terms and conditions, as well as the same incomeamounts and specific financial statement line item as other employee compensation costs arising from services rendered duringitems affected by the period.transaction. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented outside of any subtotal of operating income. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. ASU 2017-07 is effective for fiscal years and interim periods beginning after December 15, 2017, and early adoption is permitted.

The Company expects the adoption of ASU 2017-07 will change the net FAS/CAS pension adjustment within operating income, which will be offset by a corresponding change in Other income (expense), as a result of reclassifying interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects of net periodic benefit expense from operating income to Other income (expense). Additionally, the remaining FAS/CAS Adjustment within operating income will be reclassified from General and administrative expenses to Cost of product sales and service revenues. The Company adopted ASU 2017-07 on January 1, 2018 using the retrospective method and does not expect the impact to 2017 and 2016 operating income to be material when it is recast to reflect the new standard. The Company does not expect ASU 2017-07 to have a material impact on its consolidated statements of financial position, cash flows, accounting processes, or internal controls.

In May 2017, the FASB issued ASU 2017-10, "Service Concession Arrangements (Topic 853): Determining the Customer of the Operation Services", which addresses how an operating entity should determine the customer for operations under a service concession arrangement. The update clarifies that the grantor is the customer of the operation services in all cases for these arrangements. This standardguidance is effective for annual reporting periods beginning after December 15, 2017. The FASB permitted companies to adopt the new standard2021, with early but not before the original effective date of annual reporting periods beginning after December 15, 2016.adoption permitted. The Company is currently evaluating the impactimpacts of ASU 2017-10the new guidance on its consolidated financial statements and disclosures, accounting processes, or internal controls.statements.

Other accounting pronouncements issued but not effective until after December 31, 2017,2021, are not expected to have a material impact on the Company's consolidated financial position, results of operations, or cash flows.


4. AVONDALEACQUISITIONS AND DIVESTITURES


In 2010, plans were announcedAcquisition of Alion

On August 19, 2021, the Company acquired all of the outstanding common stock of Alion Holding Corp., the parent company of Alion Science and Technology Corporation (“Alion”), a technology-driven solutions provider. The Company accounted for the transaction as a business combination using the acquisition method of accounting in accordance with ASC 805 – “Business Combinations.” The preliminary purchase price was $1.79 billion, including $148 million of cash received in the acquisition. The purchase price was paid in cash and funded through the net proceeds of the Company’s issuance of $400 million aggregate principal amount of 0.670% Senior Notes due 2023 and $600 million aggregate principal amount of 2.043% Senior Notes due 2028, together with the proceeds of a $650 million term loan. See Note 13: Debt. The preliminary purchase price is subject to consolidatecustomary adjustments as provided in the purchase agreement.

Alion provides advanced engineering and R&D services in the areas of intelligence, surveillance, and reconnaissance, military training and simulation, cyber, data analytics and other next-generation technology based solutions to the DoD and intelligence community customers, with the U.S. Navy representing about one-third of current annual revenues.

evaluate information required to complete the valuations through the measurement period, which will not exceed one year from the acquisition date.

Goodwill is calculated as the excess of the purchase price over the fair value of the net assets acquired. The recognized goodwill is attributable to operational synergies and growth opportunities and was allocated to the Company's Ingalls shipbuildingTechnical Solutions segment. None of the goodwill resulting from this acquisition is expected to be amortizable for tax purposes.

Approximately $16 million of one-time acquisition-related costs was included in general and administrative expenses in the consolidated statements of operations and comprehensive income for the year ended December 31, 2021.

The Company identified Alion’s contract backlog and customer relationships as finite-lived assets with estimated fair values as of the acquisition date of $240 million and $480 million, respectively. The finite-lived assets are subject to amortization under the pattern of benefits method over six years for backlog and 20 years for customer relationships.

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. For more detailed information regarding the Company's significant accounting policy for revenue, see Note 2: Summary of Significant Accounting Policies.

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 presented abovefor 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.
77



Services - The Technical Solutions segment generates revenue primarily under U.S. Government contracts. 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 of 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 reflects 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.

As a result of this realignment, the Company's non-nuclear fleet support and nuclear and environmental services were transferred from its Newport News segment to its Technical Solutions segment. The Company's oil and gas services were transferred from its Other segment to its Technical Solutions segment, and its Other segment was dissolved. The Company has reflected the 2016 segment realignment in prior reporting periods on a retrospective basis. None of these changes impacted the Company's previously reported consolidated financial position, results of operations, or cash flows.

12.11. 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. Reporting units are aligned with the Company's businesses. The Company’s testing approach utilizes a combination of discounted cash flow analysis and comparative market multiples to determine the fair values of its businesses for comparison to their corresponding book values.


In connection with the Company’s annual goodwill impairment test as of November 30, 2017,2021, management tested goodwill for each of its four3 reporting units.units with goodwill balances. As a result of itsthe Company's annual goodwill impairment test,analysis, it estimated that the fair value of the Government Services reporting unit within the Technical Solutions segment exceeded carrying value by less than 10%. The Company determined that the estimated fair valuevalues of eachits remaining reporting unitunits exceeded by more than 10% itstheir corresponding carrying valuevalues as of November 30, 2017.2021.


In connection with the Company’s annual goodwill impairment test as of November 30, 2016, management tested goodwill for each of its four reporting units. As a result of its annual goodwill impairment test, the Company determined that the estimated fair value of each reporting unit exceeded by moreslower than 10% its corresponding carrying value as of November 30, 2016.

In conjunction with the Company's realignment of its operations on December 1, 2016, the Company allocated goodwill among new and realigned reporting units based on the relative fair values of the reporting units being realigned. Asexpected growth in operating margin, a result, during the fourth quarter of 2016, the Company performed a quantitative assessment of goodwill immediately after the realignment for each of the reporting units impacted by the Company's realignment. Based on this quantitative assessment, no impairment charge was necessary as a result of the realignment.

While the November 30, 2015, annual impairment test did not result in an impairment, considering the limited excess fair value of goodwill over its carrying value in the Oil and Gas reporting unit and the continued decline in oil prices and related industry activity levels, the Company performed an interim assessment of goodwill as of December 31, 2015. The Company’s determination of fair value as of December 31, 2015, considered industry events that occurred in the period since its annual goodwill impairment test, as well as the updated long termrevised future outlook for this reporting unit. Those events included continued deterioration in the oilbusiness, and gas markets, numerous industry-wide project deferrals, and capital spending cuts announced by industry leaders. The analysisless favorable market conditions, the Company concluded the fair value of thisits oil and gas reporting unit was less than its carrying value as of December 31, 2015, and theNovember 30, 2019. The Company recorded athe resulting goodwill impairment charge of $16$29 million at the Oiloil and Gasgas reporting unit in theits Technical Solutions segment in the fourth quarter of 2015.2019.

The Company continuously monitors industry events and changes in circumstances in the industries in which its reporting units conduct business. In consideration of the Oil and Gas reporting unit’s sensitivity to developments within its industry, the continued decline in crude oil prices, significant reductions in its customer capital spending

plans, and project delays, management concluded that an interim goodwill impairment test was necessary to determine whether it was more likely than not that the fair value of its Oil and Gas reporting unit was still higher than its carrying value as of May 31, 2015. As a result of its analysis, the Company recorded a $59 million goodwill impairment charge in the Oil and Gas reporting unit at its Technical Solutions segment in the second quarter of 2015.


Accumulated goodwill impairment losses as of each of December 31, 20172021 and 2016,2020, were $2,877$2,906 million. The accumulated goodwill impairment losses for Ingalls as of each of December 31, 2017,2021 and 2016,2020, were $1,568 million. The accumulated goodwill impairment losses for Newport News as of each of December 31, 2017,2021 and 2016,2020, were $1,187 million. The accumulated goodwill impairment losses for the Technical Solutions segment as of each of December 31, 20172021 and 2016,2020, were $122$151 million.


During the year ended December 31, 2017, the Company recorded a goodwill adjustment of $17 million in the Technical Solutions segment, primarily driven by the finalization of fair value calculations for certain assets and liabilities, as well as the net working capital adjustment, related to the acquisition of Camber. For the year ended December 31, 2016,2021, the Company recorded $278$1,024 million of goodwill related to its acquisition of Camber.Alion. For the year ended December 31, 2020, the Company recorded $350 million of goodwill related to its acquisitions of Hydroid and SIS. For the year ended December 31, 2021, the Company recorded goodwill adjustments of $13 million relating to the acquisition of SIS, primarily related to allocations to other intangible

assets. For the year ended December 31, 2020, the Company recorded goodwill adjustments of $71 million relating to the acquisition of Hydroid, primarily related to allocations to other intangible assets. For the year ended December 31, 2020, the Company allocated $35 million of goodwill at its Technical Solutions segment to an asset group that was classified as held for sale.

For the years ended December 31, 20172021 and 2016,2020, the carrying amounts of goodwill changed as follows:

Other Intangible Assets


The Company performs tests for impairment of long-lived assets whenever events or circumstances suggest that long-lived assets may be impaired. In December 2015,connection with the Alion purchase in 2021, the Company performed an impairment test on the amortizablerecorded $720 million of intangible assets that arose from the UPI acquisition, which reside in the Company’s Oil and Gas reporting unit within the Technical Solutions segment. The Oil and Gas asset group’s long lived intangible assets consist primarily ofpertaining to customer relationships and to a lesser degree, trade name and developed technology. The Company performed its impairment test considering the latest market conditions and expectations, as well as lower anticipated revenue and profitability. Based on the nature of UPI's intangible assets, the Company performed the recoverability test at the reporting unit level. In connection with the recoverability test, the Company reevaluated the remaining useful lives of the intangible assets and determined the total undiscounted pretax cash flows generated by the reporting unit over the remaining useful life of the primary asset, customer relationships. The carrying amount of the reporting unit was greater than the total undiscounted pretax cash flows, and, as a result, the intangible assets were written down by $27 million, charged against cost of sales and service revenues within income from operations at the Technical Solutions segment, and the new carrying value was adjusted to beexisting contract backlog, which is being amortized using the pattern of benefits method over a weighted-average life of seven15 years.

In connection with the CamberSIS purchase in 2016,2020, 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, and customer relationships, to beand technology, which is being amortized using the pattern of benefits method over a weighted-average life of 10 years. In connection with the USC purchase in 2015, the Company recorded $1 million of intangible assets pertaining to technology, to be amortized using the pattern of benefits method over a weighted-average life of 19nine years.


The Company's purchased intangible assets are being 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 pertainingrelating to customer relationships and existing contract backlog within Technical Solutions, as well as nuclear-powered aircraft carrier and submarine program intangible assets, with an aggregate weighted-average useful life of 4029 years based on the long life cycle of the related programs. Aggregate amortization expense for the years ended December 31, 2017, 2016,2021, 2020, and 2015,2019, was $40$86 million, $23$56 million, and $26$47 million, respectively.



The Company expects amortization for purchased intangible assets of $36$141 million in 2018, $322022, $129 million in 2019, $282023, $108 million in 2020, $262024, $98 million in 2021,2025, and $24$80 million in 2022.2026.


13.12. INCOME TAXES


Tax Reform - The Tax Act, signed into law on December 22, 2017, provides for significant changes to U.S. federal income tax law, including a provision that allows for full expensing of certain qualified property, reduction of the federal corporate income tax rate from 35.0% to 21.0%, repeal of the manufacturing deduction, and further limitations on the deductibility of certain executive compensation. The Tax Act contains other provisions that are not expected to materially affect the Company, including requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years, limitations on the deductibility of interest expense, and the creation of the base erosion anti-abuse tax.

The SEC staff issued Staff Accounting Bulletin ("SAB") 118, which provides guidance on accounting for the tax effects of the Tax Act, including a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under Accounting Standards Codification ("ASC") 740, Income Taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. Provisional estimates for the income tax effects of the Tax Act can be recorded where a company’s accounting is incomplete but a reasonable estimate can be determined. If a company cannot determine a provisional estimate for the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax law that were in effect immediately before enactment of the Tax Act.

There are no material elements of the Tax Act for which the Company’s accounting is complete. While the Company's accounting for the following elements of the Tax Act is incomplete, the Company was able to make reasonable estimates of certain effects of such elements. Accordingly, the Company recorded provisional adjustments for the following significant items:

Reduction of the U.S. federal corporate income tax rate: Beginning January 1, 2018, the Company’s income will be taxed at a 21.0% federal rate, in contrast to the previous rate of 35.0%. Under ASC 740, Income Taxes, deferred tax assets or liabilities must be recalculated as of the enactment date using current tax laws and rates expected to be in effect when the deferred tax items reverse in future periods. Consequently, the Company has recorded provisional decreases in its deferred tax assets and deferred tax liabilities of $252 million and $196 million, respectively, with a corresponding net adjustment to deferred income tax expense of $56 million for the year ended December 31, 2017. While the Company is able to make a reasonable estimate of the impact of the reduction in the U.S. federal rate, it may be affected by other analyses related to the Tax Act, including, but not limited to, accounting method changes for tax purposes that could result in adjustments to federal temporary differences.

Acceleration of Depreciation: While the Company has not completed its determination of all capital expenditures that qualify for immediate expensing, for the year ended December 31, 2017, the Company recorded a provisional benefit of $8 million based on its current intent to fully expense all qualifying expenditures. This resulted in a decrease of approximately $8 million to the Company's current income taxes payable and a corresponding decrease in its net deferred tax asset excluding the effect of the reduction in the U.S. federal corporate tax rate.

The Company’s accounting for the following element of the Tax Act is incomplete and the Company is not yet able to make a reasonable estimate of the effect. Accordingly, no provisional adjustment was recorded.

Executive Compensation: Effective January 1, 2018, the performance-based compensation exception to the $1 million deduction limitation of Internal Revenue Code Section 162(m) is repealed and the employees subject to the $1 million deduction limitation are revised to include the chief executive officer, the chief financial officer, and the next three most highly compensated employees required to be reported in the Company’s proxy statement. The only exception to this rule is for compensation that is paid pursuant to a binding contract in effect on November 2, 2017 that would have otherwise been deductible under prior Section 162(m) rules. Accordingly, any compensation paid in the future pursuant to new compensation arrangements entered into after November 2, 2017, even if performance based, will count toward the $1 million annual deduction limit if paid to an executive subject to Section 162(m). The Company has not yet completed an analysis of the binding contract requirement on the Company's various compensation plans to determine the impact of the law change.

The Company's earnings are primarily domestic, and its effective tax rate on earnings from operations for the year endedDecember 31, 2017,2021, was 38.0%12.5%, compared with 26.9%14.1% and 36.1%19.6% for 20162020 and 2015,2019, respectively.


For the year ended December 31, 2017,2021, the Company's effective tax rate differed from the federal statutory tax rate primarily as a result of a tax loss associated with the increase in deferred federal tax expense attributable to the recalculationsale of the Company's net deferredoil and gas business and estimated research and development tax asset to reflect the impact of the federal tax rate decrease included in the Tax Act, partially offset by the income tax benefits resulting from stock award settlement activitycredits for 2021 and the domestic manufacturing deduction.prior years. For the year ended December 31, 2016,2020, the Company's effective tax rate differed from the federal statutory tax rate primarily as a result of estimated research and development tax credits for prior years. For the year ended December 31, 2019, the Company’s effective tax rate differed from the federal statutory tax rate primarily as a result of the adoption of ASU 2016-09, which reduced incomeestimated research and development tax expense by the income tax benefits resulting from stock award settlement activity, a remeasurement of uncertain tax positions that resulted in a decrease in cumulative unrecognized tax benefits,credits for 2019 and the domestic manufacturing deduction. The Company’s effective tax rate for the year ended December 31, 2015, differed from the federal statutory rate primarily as a result of the amount of the goodwill impairment that is not amortizable for tax purposes and other non-deductible expenses, partially offset by the domestic manufacturing deduction.prior years.


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 uncertainunrecognized tax positionsbenefits 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.


In connection with the spin-off from Northrop Grumman, HII entered into a Tax Matters Agreement with Northrop Grumman, which governs the respective rights, responsibilities, and obligations of Northrop Grumman and the Company with respect to tax liabilities and benefits, tax attributes, tax contests, and other tax sharing regarding U.S. federal, state, local, and foreign income taxes, other taxes, and related tax returns. The Company is severally liable with Northrop Grumman for its income taxes for periods before the spin-off. HII is obligated to indemnify Northrop Grumman for tax adjustments that increase the Company's taxable income for periods before the spin-off and are of a nature that could result in a correlative reduction in HII's taxable income for periods after the spin-off. Northrop Grumman is obligated to indemnify HII for tax adjustments that decrease the Company's taxable income for periods before the spin-off and are of a nature that could result in a correlative increase in HII's taxable income for periods after the spin-off. These payment obligations only apply once the aggregate tax liability related to tax adjustments exceeds $5 million. Once the aggregate amount is exceeded, only the amount in excess of $5 million is ultimately required to be paid. In 2016 and prior years, HII incurred non-cash federal and state tax adjustments for items governed by the Tax Matters Agreement. The federal tax expense (benefit) adjustment is reported as a component of tax expense, while the state tax expense (benefit) adjustment is treated as an allowable cost in the applicable period under the terms of the Company's existing contracts and is included in general and administrative expenses. In 2016, Northrop Grumman settled with the IRS for the years 2007 through the date of the spin-off, during which HII was part of its consolidated tax returns. Northrop Grumman’s 2007 through 2011 federal tax returns are currently subject to examination due to the filing of refund claims for those years.

Unrecognized Tax Benefits - Unrecognized tax benefits represent the gross value of the Company's uncertain tax positions that have not been reflected in the consolidated statements of operations. If the income tax benefits from federal tax positions are ultimately realized, such realization would affect the Company's income tax expense, while the realization of state tax benefits would be recorded in general and administrative expenses.


The changes in unrecognized tax benefits (exclusive of interest and penalties) for the years endedDecember 31, 2017, 2016,2021, 2020, and 20152019 are summarized in the following table:

As of December 31, 20172021 and 2016,2020, the estimated amounts of the Company's uncertain tax positions, excluding interest and penalties, were liabilities of less than $1$81 million and $2$47 million,, respectively. Assuming sustainment of these positions, as of December 31, 20172021 and 2016,2020, the reversal of less than $1$63 million and $2$34 million, respectively, of the amounts accrued would favorably affect the Company's effective federal income tax rate in future periods.

In 2016, the Company settled a state uncertain tax position through agreement with the applicable taxing authority. The net impact of the settlement was not material to HII’s consolidated financial position, results of operations, or cash flows.


The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. Related toAs a result of the unrecognized tax benefits noted above, income tax expense increased by $1 million in 2021 for interest and penalties, resulting in a liability of $3 million for interest and penalties as of December 31, 2021. In 2020, there was a net decrease in income tax expense of less than $1 million in 2017 for interest and penalties, resulting in no material liability for interest and penalties as of December 31, 2017. The 2017 changes in interest and penalties related to statute of limitation expirations. In 2016, there was a net decrease in income tax expense of $2 million for interest and penalties, resulting in a total liability of $1$2 million for interest and penalties as of December 31, 2016.2020. The 20162020 changes in interest expense related to a

Although the Company believes it has adequately provided for all uncertainunrecognized tax positions,benefits, amounts asserted by taxingtax authorities could be greater than the Company's accrued position. Accordingly, additional provisions for federal and state income tax related matters could be recorded in the future as revised estimates are made or the underlying matters are effectively settled or otherwise resolved.

Deferred Income Taxes - Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and for income tax purposes. As described above, deferred tax assets and liabilities are calculated as of the balance sheet date using current tax laws and rates expected to be in effect when the deferred tax items reverse in future periods. As a result of the reduction in the corporate income tax rate from 35.0% to 21.0% under the Tax Act, the Company revalued its net deferred tax assets as of December 31, 2017. Net deferred tax assetsliabilities are classified as long-term deferred tax assetsliabilities in the consolidated statements of financial position.

15.14. 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 ComplaintsComplaint - In 2015, the Company received a Civil Investigative Demand from the Department of Justice ("DoJ") relating to an investigation of certain allegedly non-conforming parts the Company purchased from one of its suppliers for use in connection with U.S. Government contracts. The Company has cooperated with the DoJ in connection with its investigation. In 2016, the Company was made aware that it is a defendant in a qui tamFalse Claims Act lawsuit filed under sealpending in the U.S. District Court for the Middle District of Florida related to the Company’s purchases of the allegedly non-conforming parts from a supplier for use in connection with U.S. Government contracts. In August 2019, the supplier. Depending uponDepartment of Justice (“DoJ”) declined to intervene in the outcomelawsuit, and the lawsuit was unsealed. The court dismissed the complaint in September 2021, and the plaintiff has appealed the dismissal to the United States Court of this matter,Appeals for the 11th Circuit.

Insurance Claims - In September 2020, the Company could be subjectfiled 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 6 other reinsurers seeking similar relief. Prior to civil penalties, damages, and/or suspension or debarment from future U.S. Government contracts, which could havefiling the complaint and initiating the arbitration proceedings, the Company provided a material adverse effect on its consolidated financial position, resultsnotice of operations, or cash flows. The matter remains sealed and givenloss to the current posturereinsurers, but, to date, none of the matter,reinsurers have acknowledged coverage. The full extent of the Company's losses resulting from COVID-19 have not yet been determined. In July 2021, the Vermont court granted the reinsurers’ motion for judgment on the pleadings, finding that, because the Company is unablecontinued to estimate an amount or rangeoperate through the pandemic, the Company’s reduction of reasonably possiblebusiness not accompanied by a complete loss of use fell short of the required “direct physical loss or damage to express an opinionproperty.” The Company has appealed the decision to the Vermont Supreme Court. Although the Company still believes its position is well-founded, no assurances can be provided regarding the ultimate outcome.resolution of this matter.

In September 2021, the Company filed a complaint in the Superior Court of Delaware, seeking a judgment against certain insurers for breach of contract and breach of the implied covenant of good faith and fair dealing under three
90


representations and warranties insurance policies purchased in connection with the Company’s acquisition of Hydroid. The policies insure the Company against losses relating to the seller’s breach of certain representations and warranties in the Hydroid acquisition agreement. The coverage limit under the insurance policies is $70 million, and the Company believes it has incurred losses equal to at least that amount as a result of breaches of the acquisition agreement. 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.


In January 2013, the Company disclosed to the DoD, including the U.S. Navy, and the U.S. Department of Homeland Security, including the U.S. Coast Guard, pursuant to the FAR, that it had initiated an internal investigation regarding whether certain employees at Ingalls mischarged time or misstated progress on Navy and Coast Guard contracts. The Company conducted an internal investigation, led by external counsel, and took remedial actions, including the termination of employees in instances where the Company believed grounds for termination existed. The Company provided information regarding its investigation to the relevant government agencies, and agreed with the U.S. Navy and U.S. Coast Guard that they would initially withhold $24 million in payments on existing contracts pending receipt of additional information from the Company's internal investigation. The U.S. Navy subsequently reduced its portion of the withhold from $18.2 million to $4.7 million, and the U.S. Coast Guard reduced its withhold from $5.8 million to $3.6 million. In September 2017, the U.S. Navy and the U.S. Coast Guard paid the Company the respective remaining amounts they were withholding.

In June 2015, the DoJ informed the Company that it was investigating the matters disclosed by the Company to the DoD in January 2013. In August 2017, the Company settled the matters with the DoJ. The settlement did not have a material effect on the Company’s consolidated financial position, results of operations, or cash flows.

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 average cost per casecosts to resolve cases during the years ended December 31, 2017, 2016,2021, 2020, and 2015 was2019 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 - The Company and its predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the “Republic”"Republic") since 2002 over a contract for the repair, refurbishment, and modernization at Ingalls of two2 foreign-built frigates. The case proceeded towards arbitration, then appeared to settle favorably, but the settlement was overturned in court and the matter returned to litigation. In March 2014, the Company filed an arbitral statement of claim asserting breaches of the contract and $173 million in damages plus substantial interest and litigation expenses. In July 2014, thecontract. The Republic filed in the arbitration a statement of defense denying alldenied the Company’s allegations and a counterclaim alleging late redelivery ofasserted counterclaims. In February 2018, the frigates, unfinished work, and breach of warranty and asserting damages of $61 million plus interest. An arbitration hearing was held in January 2015, andarbitral tribunal awarded the Company cannot predict whenapproximately $151 million on its claims and awarded the arbitration panel will render a decision.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 outcomeresolution of this matter.


The Company is party to various other claims, and legal proceedings, and investigations that arise in the ordinary course of business.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, and legal proceedings, and investigations will not have a material effect on its consolidated financial position, results of operations, or cash flows, itthe 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.


15. LEASES

Many land, warehouse, and office space leases include renewal terms that can extend the lease term. The exercise of lease renewal options is at our sole discretion. The depreciable life of assets and leasehold improvements is generally limited by the expected lease term. The Company's lease agreements do not generally contain material residual value guarantees, material restrictive covenants, or purchase options.

16. 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 previously unanticipated contract costs. These estimates are based upon management's best assessment of the underlying causal events and circumstances and are included in determining contract profit marginsrecognized to the extent of expected recovery based onupon contractual entitlements and the probability of successful negotiation with the customer. As of December 31, 2017,2021, amounts recognized amounts related toin 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 may enterenters into joint ventures, teaming agreements, and other business arrangements to supportin connection with the Company's products and services.services or to pursue strategic objectives. The Company generally strivesattempts 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.


92


In the ordinary course of business, the Company may guarantee obligations of its subsidiaries under certain contracts. Generally, the Company is liable under such an arrangementguarantees 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 December 31, 2017,2021, 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 wherewhen 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 in 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 December 31, 2017,2021, the probable estimable future cost for environmental remediation was $1 million, which is accrued in other current liabilities.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 sharesshare 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 projects progressremediation progresses or the Company incurs additional remediation obligations 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. In addition, there are certain potential remediation sites where the costs of remediation cannot be reasonably estimated.


Financial Arrangements - In the ordinary course of business, HII uses standby 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 primarilyprincipally to support the Company's self-insured workers' compensation plans. As of December 31, 2017,2021, the Company had $15 million in standbyissued but undrawn letters of credit, issued but undrawn, as indicated in Note 14:13: Debt, and $258$276 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 HIIthe 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 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. Under the 1985 settlement agreement, the Company has not recognized as allowable cumulative billable costs of approximately $120 million resulting from 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.

In January 2022, the Navy Contracting Officer issued a written determination that the Ingalls Shipbuilding Material Management and Accounting System has three significant deficiencies, resulting in a 5% withhold of payments on certain invoices issued under one contract. Ingalls Shipbuilding will submit a corrective action plan, and the withhold will be reduced to 2% if the Contracting Officer determines the corrective action plan has been implemented and is effective. The withhold will terminate and withheld funds returned to the Company when the Contracting Officer determines that the significant deficiencies have been corrected. Although the Company believes the ultimate resolution of this matter will not have a material effect on its consolidated financial position, results of operations, or cash flows, it cannot predict or give assurances regarding the ultimate outcome of this matter.

Newport News has four2 collective bargaining agreements covering represented employees, one ofwhich expire in December 2022 and April 2024, and 1 that expired in November 2021, which covers approximately 50% of Newport News employees and was renewed July 2017. The remaining collective bargaining agreements at Newport News expire August 2018, December 2018, and November 2020.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 five5 collective bargaining agreements covering represented employees, all of which expire in March 2022.2026. Approximately 3515 Technical Solutions craft employees at the Hanford Site near Richland, Washingtonin Klamath Falls, Oregon are represented under an indefinite DoE site stabilization agreement. covered by 1 collective bargaining agreement that expires in June 2025.

The Company believes its relationshipreached a tentative agreement with its employees is satisfactory.representatives of United Steelworkers ("USW") Local 8888 (Newport News) members on a new labor agreement in November 2021, but the members of the bargaining unit declined to ratify the contract. The Newport News and USW negotiation teams continued negotiations and reached a tentative agreement on another labor agreement in January 2022. The Company expects the members of the bargaining unit to vote on the new agreement in the near future. The USW Local 8888 members are continuing to work under the terms and conditions of the expired collective bargaining agreement, but the members may call for a strike, or the Company may declare a lock-out, upon 48 hours notice. In the event the Company and USW Local 8888 members fail to reach a collective bargaining agreement and the union calls for a strike or the Company declares a lock-out, the Company's consolidated results of operations could be negatively impacted on a material basis.
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.believes its relationship with its employees is satisfactory.


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.


Operating Leases - Rental expense for operating leases for the years endedDecember 31, 2017, 2016, and 2015, was $63 million, $69 million, and $62 million, respectively.

17. IMPACTS FROM HURRICANES

In August 2005, the Company's Ingalls operations were significantly impacted by Hurricane Katrina, and the Company's shipyards in Louisiana and Mississippi sustained significant windstorm damage from the hurricane. As a result of the storm, the Company incurred costs to replace or repair destroyed or damaged assets, suffered losses

under its contracts, and incurred substantial costs to clean up and recover its operations. At the time of the storm, the Company had an insurance program that provided coverage for, among other things, property damage, business interruption impact on net profitability, and costs associated with clean-up and recovery. The Company recovered $677.5 million of its Hurricane Katrina claim from participating program insurers, which included $180 million from Factory Mutual Insurance Company (“FM Global”) in settlement of litigation arising from a disagreement concerning the coverage of certain losses related to Hurricane Katrina.

In January 2011, the Company, through a predecessor-in-interest, filed suit in Superior Court in California against Aon Risk Insurance Services West, Inc. ("Aon"), which acted as broker to the predecessor-in-interest in connection with the policy with FM Global, seeking damages for breach of contract, professional negligence and negligent misrepresentation, as well as declaratory relief. Those included damages unrecovered from FM Global plus costs, legal fees, and expenses incurred in the lawsuit against FM Global, as well as interest. In January 2014, the Company amended its complaint to allege fraud and seek punitive damages.

In May 2015, the Company and Aon entered into a settlement agreement, pursuant to which Aon made a cash payment of $150 million to the Company and the Company released its claims against Aon. In the second quarter of 2015, the $150 million settlement was recorded as a gain in operating income and the Company recorded a credit to the U.S. Government, which resulted in a reduction in operating income of $14 million. Should the U.S. Government disagree with the Company’s allocation of proceeds, the Company may be required to allocate additional amounts to the U.S. Government. The $150 million gain and allowable cost credit resulted in a net favorable impact to operating income for the year ended December 31, 2015, of $136 million.

18. EMPLOYEE PENSION AND OTHER POSTRETIREMENT BENEFITS


The Company provides eligible employees defined benefit pension plans, defined contribution benefit plans, and other postretirement benefit plans to eligible employees.plans. Non-collectively bargained defined benefit pension benefits accruing under the traditional years of service and compensation formula were amended in 2009 to freeze future service accruals and have beenwere replaced with a cash balance benefit for all current non-collectively bargained employees. Except for the major collectively bargained plan at Ingalls, the Company's qualified defined benefit pension plans are frozen to new entrants. The Company's policy is to fund its qualified defined benefit pension plans at least to the minimum amounts required under U.S. Government regulations.


Plan obligations are measured based on the present value of projected future benefit payments to participants for services rendered to date. The measurement of projected future benefits is dependent on the terms of each individual plan, demographics, and valuation assumptions. No assumption is made regarding any potential changes to the benefit provisions beyond those to which the Company is currently committed, for example under existing collective bargaining agreements.


The Company also sponsors 401(k) defined contribution pension plans in which most employees, including certain hourly employees are eligible to participate. Company contributions for most defined contribution pension plans are based on the matching of employee contributions up to 4% of eligible compensation. Certain hourly employees are covered under a target benefit plan. In addition to the 401(k) defined contribution pension benefit formula, non-collectively bargained employees hired after June 30, 2008, and certain collectively bargained employees hired after July 10, 2017, are
94


eligible to participate in a defined contribution benefit program in lieu of a defined benefit pension plan. The Company's contributions to the qualified defined contribution pension plans for the years endedDecember 31, 2017, 2016,2021, 2020, and 2015,2019, were $78$140 million, $71$130 million, and $73$120 million, respectively.


The Company also sponsors defined benefit and defined contribution pension plans to provide benefits in excess of the qualifiedtax-qualified limits. The liabilities related to these plans as of December 31, 2017,2021, were $182$240 million and $32$45 million, respectively, and as of December 31, 2016,2020, were $154$229 million and $29$38 million, respectively. Assets, primarily in the form of Level 1 marketable securities held in grantor trusts, are intended to fund certain of these obligations. The trusts’ fair values supporting these liabilities as of December 31, 20172021 and 2016,2020, were $94$220 million and $82$182 million, respectively, of which $61$173 million and $51$142 million, respectively, were related to the non-qualified defined benefit pension plans.


The Company provides contributory postretirement health care and life insurance benefits to a dominantly closed group of eligible employees, retirees, and their qualifying dependents. Covered employees achieve eligibility to participate in these contributory plans upon retirement from active service if they meet specified age, years of service, and grandfathered requirements. Benefits are not guaranteed, and the Company reserves the right to

amend or terminate coverage at any time. The Company's contributions for retiree health care benefits are subject to caps, which limit Company contributions when spending thresholds are reached.


The measurement date for all of the Company's retirement related plans is December 31. The costs of the Company's defined benefit pension plans and other postretirement benefit plans for the years endedDecember 31, 2017, 2016,2021, 2020, and 2015,2019, were as follows:

Health Care Cost Trend Rate - The health care cost trend rate represents the annual rates of change in the cost of health care benefits based on estimates of health care inflation, changes in health care utilization or delivery patterns, technological advances, government mandated benefits, and other considerations. Using a combination of market expectations and economic projections onas of December 31, 2017,2021, the Company selected an expected initial health care cost trend rate of 6.00%5.50% and an ultimate health care cost trend rate of 4.50% to be reached in 2025. On 2027. As of December 31, 2016,2020, the Company assumed an expected initial health care cost trend rate of 6.50%5.50% and an ultimate health care cost trend rate of 5.00%4.50% to be reached in 2025.2026.

The Employee Retirement Income Security Act of 1974 ("ERISA"), including amendments under pension relief, defines the minimum amount that must be contributed to the Company's qualified defined benefit pension plans. In determining whether to make discretionary contributions to these plans above the minimum required amounts, the Company considers various factors, including attainment of the funded percentage needed to avoid benefit restrictions and other adverse consequences, minimum CAS funding requirements, and the current and anticipated
97


future funding levels of each plan. The Company's contributions to its qualified defined benefit pension plans are affected by a number of factors, including published IRS interest rates, the actual return on plan assets, actuarial assumptions, and demographic experience. These factors and the Company's resulting contributions also impact the funded status of each plan. The Company made the following contributions to its defined benefit pension plans and other postretirement benefit plans for the years ended December 31, 2017, 2016,2021, 2020, and 2015:2019:

In the third quarter of 2017, the Company concluded negotiations on one of its collective bargaining agreements, which required an amendment to one of its pension plans. As a result of the amendment, the remeasurement of the plan increased the pension liability and pre-tax accumulated other comprehensive loss by approximately $76 million.


For the year ending December 31, 2018,2022, the Company expects its cash contributions to its qualified defined benefit pension plans to be $508less than $1 million, all of which will be discretionary. For the year ending December 31, 2018,2022, the Company expects its cash contributions to its other postretirement benefit plans to be approximately $35$34 million.


The following table presents estimated future benefit payments, using the same assumptions used in determining the Company's benefit obligations, as of December 31, 2017.2021. Benefit payments depend on future employment and compensation levels, years of service, and mortality. Changes in any of these factors could significantly affect these estimated amounts.

Pension Plan Assets


Pension assets include public equities, government and corporate bonds, cash and cash equivalents, private real estate funds, private partnerships, hedge funds, and other assets. Plan assets are held in a master trust and overseen by the Company's Investment Committee. All assets are externally managed through a combination of active and passive strategies. Managers may only invest in the asset classes for which they have been appointed.
 
The Investment Committee is responsible for setting the policy that provides the framework for management of the plan assets. The Investment Committee has set the minimum and maximum permitted values for each asset class in the Company's pension plan master trust for the year ended December 31, 2017,2021, as follows:

The general objectives of the Company's pension asset strategy are to earn a rate of return over time to satisfy the benefit obligations of the plans, meet minimum ERISA funding requirements, and maintain sufficient liquidity to pay benefits and address other cash requirements within the master trust. Specific investment objectives include reducing the volatility of pension assets relative to benefit obligations, achieving a competitive total investment return, achieving diversification between and within asset classes, and managing other risks. Investment objectives for each asset class are determined based on specific risks and investment opportunities identified. Decisions regarding investment policies and asset allocationallocations are made with the understanding of the historical and

prospective return and risk characteristics of various asset classes, the effect of asset allocations on funded status, future Company contributions, and projected expenditures, including benefits.benefit payments. The Company updates its asset allocations periodically. The Company uses various analytics to determine the optimal asset mix and considers plan obligation characteristics, duration, liquidity characteristics, funding requirements, expected rates of return, regular rebalancing, and the distribution of returns. Actual allocations to each asset class could vary from target allocations due to periodic investment strategy changes, short-term market value fluctuations, the length of time it takes to fully implement investment allocation positions, such as real estate and other alternative investments, and the timing of benefit payments and Company contributions.


Taking into account the asset allocation ranges, the Company determines the specific allocation of the master trust's investments within various asset classes. The master trust utilizes select investment strategies, which are executed through separate account or fund structures with external investment managers who demonstrate experience and expertise in the appropriate asset classes and styles. The selection of investment managers is

done with careful evaluation of all aspects of performance and risk, demonstrated fiduciary responsibility, investment management experience, and a review of the investment managers' policies and processes. Investment performance is monitored frequently against appropriate benchmarks and tracked to compliance guidelines with the assistance of third partythird-party consultants and performance evaluation tools and metrics.
 
Plan assets are stated at fair value. The Company employs a variety of pricing sources to estimate the fair value of its pension plan assets, including independent pricing vendors, dealer or counterparty-supplied valuations, third-party appraisals, and appraisals prepared by the Company's investment managers or other experts.


Investments in equity securities, common and preferred, are valued at the last reported sales price when an active market exists. Securities for which official or last trade pricing on an active exchange is available are classified as Level 1. If closing prices are not available, securities are valued at the last trade price, if deemed reasonable, or a broker's quote in a non-active market, and are typically categorized as Level 2.


Investments in fixed-income securities are generally valued by independent pricing services or dealers who make markets in such securities. Pricing methods are based upon market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders, and fixed-income securities typically are categorized as Level 2.


Investments in collective trust funds and commingled funds based on thethat use of Net Asset Values (“NAV”) are valued based on the redemption price of units owned by the master trust, which is based on the current fair values of the funds’ underlying assets, as reported by the investment manager.


Investments in hedge funds generally do not have readily available market quotations and are estimated at fair value, which primarily utilizes NAV or the equivalent, as a practical expedient, as reported by the investment manager. Hedge funds usually have restrictions on redemptions that might affect the ability to sell the investment at NAV in the short term.


Real estate funds are typically valued through updated independent third-party appraisals, which are adjusted for changes in cash flows, market conditions, property performance, and leasing status. Since real estate funds do not have readily available market quotations, they are generally valued at NAV or its equivalent, as a practical expedient, as reported by the asset manager. Redemptions from real estate funds are also subject to various restrictions.


Private partnership interests include debt and equity investments. These investments are valued based on NAVs or their equivalents, adjusted for capital calls and distributions, fromreported by the respective general partners. The terms of the partnerships range from seven to ten or more years, and investors do not have the option to redeem their interests in these partnerships. As of December 31, 2017,2021, unfunded commitments to private partnerships were $112$563 million.


Management reviews independently appraised values, audited financial statements, and additional pricing information to evaluate the net asset values. For the very limited group of investments for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value, additional information is obtained from the investment manager and evaluated internally to determine whether any adjustments are required to reflect fair value.


99


The Company might be unable to quickly liquidate some assets at amounts close or equal to fair value in order to meet the plans'plan liquidity requirements or respond to specific events, such as the creditworthiness of any particular issuer or counterparty. Illiquid assets are generally long-term investments that complement the long-term nature of the Company's pension obligations and are generally not used to fund benefit payments in the short term. Management monitors liquidity risk on an ongoing basis and has procedures designed to maintain adequate liquidity for plan requirements.


The master trust has considerable investments in fixed income securities for which changes in the relevant interest rate of a particular instrument might result in the inability to secure similar returns upon the maturity or sale.sale of the instrument. Changes in prevailing interest rates might result in an increase or decrease in fair value of the instrument. Investment managers are permitted to use interest rate swaps and other financial derivatives to manage interest rate and credit risks.



Counterparty risk is the risk that a counterparty to a financial instrument held by the master trust will default on its commitment. Counterparty risk is generally related to over-the-counter derivative instruments used to manage risk exposure to interest rates on long-term debt securities. Certain agreements with counterparties employ set-off agreements, collateral support arrangements, and other risk mitigation practices designed to reduce the net credit risk exposure in the event of a counterparty default. CreditThe Company has credit policies and processes are in place tothat manage concentrations of risk by seeking to undertake transactions with large well-capitalized counterparties and by monitoring the creditworthiness of these counterparties.


Certain investments that are measured at fair value using NAV per share (or its equivalent) as a practical expedient are not required to be categorized in the fair value hierarchy table. The total fair value of these investments is included in the table below to permit reconciliation of the fair value hierarchy to amounts presented in the funded status table above.

The 2012 Plan permits awards of stock options, stock appreciation rights, and other stock awards. Each stock option grant is made with an exercise price of not less than 100% of the closing price of HII's common stock on the date of grant. Stock awards, in the form of RPSRs, restricted stock rights ("RSRs"), and stock rights, are granted to key employees and members of the board of directors without payment to the Company. The 2012 Plan authorized (i) 3.4 million new shares; plus (ii) any shares subject to outstanding awards under the 2011 Plan that were subsequently forfeited to the Company; plus (iii) any shares subject to outstanding awards under the 2011 Plan that were subsequently exchanged by the participant as full or partial payment to the Company in connection with any such award or exchanged by a participant or withheld by the Company to satisfy the tax withholding obligations

Vested awards include stock awards that fully vested during the year based on the level of achievement of the relevant performance goals. The performance goals for outstanding RPSRs granted in 2017, 2016,2021, 2020, and 2015 are2019 were based on twothree metrics as defined in the grant agreements: earnings before interest, taxes, depreciation, amortization, and pension ("EBITDAP"), weighted at 50%40%, and pension-adjusted return on invested capital ("ROIC"), weighted at 50%40%, and relative EBITDAP growth, weighted at 20%.

Stock Options

Effect The Company's EBITDAP growth will be measured against EBITDAP growth of the Spin-Off - Prior to the spin-off, HII's currentS&P Aerospace and former employees received stock options under Northrop Grumman's stock-based award plans (the "Northrop Grumman Plan"). As of the date of the spin-off, the stock options under the Northrop Grumman Plan were converted to stock options under the 2011 Plan. The conversion was effected so that the outstanding stock options held by the Company's current and former employees on the distribution date were adjusted to reflect the value of the distribution, such that the intrinsic value of the stock options was not diluted at the time of, and due to, the separation. This was achieved using the conversion rate included in the spin-off agreement. Unless otherwise stated, share amounts and share prices detailed below were retroactively adjusted to reflect the impact of the conversion. The Company measured the fair value of the stock options immediately before and after the conversion, and there was no incremental compensation expense associated with the conversion.Defense Select Index.


The following is a description of the Northrop Grumman Plan stock options, which were converted into stock options under the 2011 Plan.

Converted Stock Options - As of the date of the spin-off, outstanding stock options held by HII's current and former employees under the Northrop Grumman Plan were converted to stock options of HII under the 2011 Plan. Based on the conversion factor of 1.65, included in the spin-off agreement, approximately 1.0 million stock options under the Northrop Grumman Plan were converted into approximately 1.6 million stock options under the 2011 Plan, approximately 1.4 million of which were fully vested at the time of conversion. Outstanding stock options granted prior to 2008 generally vested in 25% increments over four years from the grant date and expire ten years after the grant date. Stock options granted in 2008 and later vested in 33% increments over three years from the grant date and expire seven years after the grant date. The cumulative intrinsic value of the stock options at conversion was maintained in the conversion, and totaled $15 million at March 31, 2011.

Compensation expense for the outstanding converted stock options was determined at the time of grant by Northrop Grumman. No stock options were granted during the years endedDecember 31, 2017, 2016, and 2015. The fair value of the stock options was expensed on a straight-line basis over the vesting period of the options. The fair value of each of the stock options was estimated on the date of grant using a Black-Scholes option pricing model.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING


Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, management has conducted an assessment, including testing, using the criteria in Internal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). The Company’s system of internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.


Based on its assessment, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2017,2021, based on criteria in Internal Control – Integrated Framework (2013), issued by the COSO. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2017,2021, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which is included in Item 8.
