to our
shareholders, employees,
customers and communities:

in late 2015, when we launched hii’s “path to 2020” business strategy, we said we were confident we had a sustainable
approach and proven management team in place for long-term value creation. now that we’ve passed the midway point of
our five-year plan, we are proud to report that we are making steady progress that will transform the business well beyond
2020. here are just a few of the highlights:

• Our capital program remains on schedule. Last year’s
milestones included the beginning of the East Bank
reactivation at ingalls shipbuilding and continued
outfitting of the Joint Manufacturing Assembly Facility
at newport news shipbuilding. We remain committed
to having our shipyards prepared for current and future
navy programs.

• We continued to grow our government services business
through our technical solutions division. noteworthy in
2018 were the acquisition of g2 inc., a nationally recognized
cybersecurity solutions and services company, and
new, long-term contract awards for technical solutions’
nuclear & environmental group.

• We distributed $920 million to shareholders through

dividends and share repurchases.

atomic testing museum in las Vegas.

Our many successes in 2018 are also reflected in our strong
financial results. We recorded record-high revenues of
$8.2 billion in 2018, an increase of approximately 10 percent
over 2017. Operating income was $951 million and operating
margin was 11.6 percent. cash from operations in 2018
was $914 million, and free cash flow was $512 million,
compared to $814 million and $453 million, respectively,
in 2017. Diluted earnings per share was $19.09, compared
to $10.46 in 2017. New contract awards for the year were
approximately $9.8 billion, bringing total backlog to $23
billion as of dec. 31, 2018.

All of these accomplishments are a credit to our workforce—
now more than 40,000 strong and spread across 42 states
and 13 countries. While hii is only eight years old, we have a
133-year legacy of workforce development at Newport News,
and we were proud to build on that in 2018, announcing with

the commonwealth of Virginia our intent to hire as many as
7,000 new shipbuilders over the next five years. Likewise,
technical solutions partnered with Kellogg brown & root
in 2018 to establish and manage australia’s new naval
shipbuilding college, and ingalls announced a partnership in
2018 to construct talent development labs at high schools
in mississippi and alabama.

We strongly believe that hii’s employees have the best
jobs on the planet, and we’re empowering them to make
their jobs even better. Also, we are proud to be ranked
No. 21 on Forbes’ first list of the best employers for new
college graduates.

Our “Healthy Body, Healthy Wallet, Healthy Mind” benefits
and wellness strategy is also paying dividends for our
employees and their dependents. in 2018, we opened

hii will deliver the America-class amphibious assault ship Tripoli (LHA 7) in 2019.

HII Family Vision Centers in Virginia and Mississippi, and we
established on-site employee assistance program counselors
at the existing HII Family Health Centers. We also launched
the Financial Wellbeing Portal online and the SmartPath
financial education program, giving employees the tools and
know-how to make smart money decisions—in most cases,
decades before retirement planning becomes a priority.

Unfortunately, some of our employees will remember 2018
as a year of hardship. In September, Hurricane Florence
dumped record amounts of rain on north carolina and south
carolina, including more than 1,200 hii employees who call
those states home. A few weeks later, Hurricane Michael made
landfall just a few miles from a technical solutions facility
in Florida. While we made two donations totaling $150,000
to the American Red Cross’ Disaster Relief Fund, we were
most proud of the way hii’s employees rallied to protect and
recover our facilities in panama city beach and support our
colleagues who work there.

our response following those storms—indeed, the way
we achieved every accomplishment in 2018—is a testament
to our “Hard Stuff Done Right” trademark and our
commitment to persistent and sustainable value creation
for all of our stakeholders.

Like so many other things in HII’s culture, the “Path to 2020”
is a journey—not a destination. We’re proud of how far we’ve
come over the last three years and excited to see what else
we will accomplish.

Thank you, as always, for your investment in HII and for
helping us shape the future.

PART I

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, and oil and gas markets.

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, mission
driven innovative solutions ("MDIS"), nuclear and environmental, and oil and gas services through our Technical
Solutions segment. Headquartered in Newport News, Virginia, we employ approximately 40,000 people both
domestically and internationally.

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"). The LHA is a key
component of the U.S. Navy-Marine Corps 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 are currently
constructing Tripoli (LHA 7), scheduled for delivery in 2019, and Bougainville (LHA 8).

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 2017 and USS John P. Murtha
(LPD 26) in 2016, and we are currently constructing Fort Lauderdale (LPD 28) and Richard M. McCool Jr. (LPD 29),
with Fort Lauderdale (LPD 28) scheduled for delivery in 2021. In 2018, we were awarded an advance procurement
contract for LPD 30 (unnamed).

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 Arleigh Burke class (DDG 51) destroyers to
the U.S. Navy, including Ralph Johnson (DDG 114) in 2017 and USS John Finn (DDG 113) in 2016. In 2013, we
were awarded a multi-year contract totaling $3.3 billion for construction of five Arleigh Burke class (DDG 51)
destroyers. In September 2018, we were awarded a multi-year contract totaling $5.1 billion for construction of six
additional Arleigh Burke class (DDG 51) destroyers. We are currently constructing Paul Ignatius (DDG 117), Delbert
D. Black (DDG 119), Frank E. Petersen Jr. (DDG 121), Lenah H. Sutcliffe Higbee (DDG 123), and Jack H. Lucas
(DDG 125), with the first two ships scheduled for delivery in 2019.

National Security Cutters

The U.S. Coast Guard's recapitalization program is designed to replace aging and operationally expensive 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 Munro (NSC
6) and USCGC Kimball (NSC 7) to the U.S. Coast Guard in 2016 and 2018, respectively. Midgett (NSC 8) and
Stone (NSC 9) are currently under construction and scheduled for deliveries in 2019 and 2020, respectively. In
2018, we were awarded long-lead-time material and construction contracts for NSC 10 (unnamed) and NSC 11
(unnamed).

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. 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 30 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. Beginning in 2009, we
received contract awards totaling $7.6 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 $15.2 billion for detail design and construction of the Gerald R. Ford class (CVN 78) aircraft
carriers Enterprise (CVN 80) and CVN 81 (unnamed).

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). We believe our position as the
exclusive designer and builder of nuclear-powered aircraft carriers, our RCOH performance on the first six Nimitz
class (CVN 68) carriers, and our highly trained workforce, as well as the fact that 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 work on Gerald R. Ford class (CVN 78) aircraft carriers.

The U.S. Navy awarded us a 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 was 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 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 opportunity 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 61 submarines to the U.S. Navy since 1960, comprised
of 47 fast attack and 14 ballistic missile submarines. Of the 51 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.

Virginia 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.
Under the present 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 alternate between Electric Boat and us.

The four submarines of the first block and six submarines of the second block of Virginia class (SSN 774)
submarines have been delivered. In 2008, the team was awarded a construction contract for the third block of eight
Virginia class (SSN 774) submarines. The multi-year contract increased construction from one submarine per year
to two submarines per year. The first submarine under this contract was delivered in 2014 and the last submarine of
the third block is scheduled for delivery in 2019. In 2014, the team was awarded a construction contract for the
fourth block of ten Virginia class (SSN 774) submarines, continuing the two submarines per year production rate.
The first submarine of the Block IV contract is scheduled for delivery in 2019, and the last is scheduled for delivery
in 2023.

Columbia Class (SSBN 826) Submarines

Newport News is participating in designing 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 perform design work as a subcontractor to Electric Boat, and we have entered into a teaming agreement
with Electric Boat to build modules for the entire Columbia class (SSBN 826) submarine program that leverages our
Virginia class (SSN 774) experience. We have been awarded contracts from Electric Boat to begin integrated
product and process development and provide long-lead-time material and advance construction for the Columbia
class (SSBN 826) program. Construction of the first Columbia class (SSBN 826) submarine is expected to begin in
2021.

Naval Nuclear Support Services

Newport News provides additional services to and in support of the U.S. Navy, ranging from services supporting the
Navy's carrier and submarine fleets to maintenance services at U.S. Navy training facilities. Fleet services include
design, construction, maintenance, and disposal activities for in service U.S. Navy nuclear ships worldwide through
mobile and in-house capabilities. We also provide maintenance services on nuclear reactor prototypes, such as
those at the Kenneth A. Kesselring Site, a research and development facility in New York that supports the U.S.
Navy.

ownership interest in N3B, which, in 2017, was awarded the Los Alamos Legacy Cleanup Contract at the DoE/
National Nuclear Security Administration’s Los Alamos National Laboratory located northwest of Santa Fe, New
Mexico. We have a 23% ownership interest in MSTS, which, in 2017, was awarded a contract for site management
and operations at the Nevada National Security Site located northwest of Las Vegas, Nevada. We have a 34%
ownership interest in SRNS, which provides site management and operations at the DoE's Savannah River Site
near Aiken, South Carolina.

Oil and Gas Services

Our oil and gas services provide engineering, procurement, and construction management services to the oil and
gas industry for major pipeline, production, and treatment facilities. These services include full life-cycle services for
domestic and international projects, from concept identification through detail design, execution and construction,
and decommissioning. We also offer related field services, including survey, inspection, commissioning and start-
up, operations and maintenance, and optimization and debottlenecking.

Corporate

HII was incorporated in Delaware on August 4, 2010, and became an independent, publicly owned company in
2011, when we were spun-off from Northrop Grumman. Our principal executive offices are located at 4101
Washington Avenue, Newport News, Virginia 23607. Our telephone number is (757) 380-2000, and our home page
on the Internet is www.huntingtoningalls.com. References to our website in this report are provided as a
convenience and do not constitute, and should not be viewed as, incorporation by reference of the information
contained on, or available through, the website. Accordingly, such information should not be considered part of this
report.

Customers

Our revenues are primarily derived from the U.S. Government. In 2018, 2017, and 2016, approximately 88%, 87%,
and 89%, respectively, of our revenues were generated from the U.S. Navy, and approximately 5%, 6%, and 6%,
respectively, were generated from the U.S. Coast Guard. In 2018, 2017, and 2016, we generated approximately
3%, 3%, and 4%, respectively, of our revenues from commercial customers and 4%, 4%, and 1%, respectively, from
other government agencies.

Intellectual Property

We develop and incorporate into our vessels new technologies, manufacturing processes, and systems-integration
processes. In addition to owning a large portfolio of proprietary intellectual property, we license intellectual property
rights to and from others. The U.S. Government receives non-exclusive licenses to our intellectual property
developed in the performance of U.S. Government contracts and unlimited license rights in technical data
developed under our U.S. Government contracts when such data is developed entirely at government expense. The
U.S. Government may use or authorize others to use the intellectual property licensed to the government. While our
intellectual property rights are important to our operations, we do not believe that any existing patent, license, or
other intellectual property right is of such importance that its loss or termination would have a material impact on our
business.

Seasonality

No material portion of our business is seasonal. The timing of our revenue recognition is based on several factors,
including the timing of contract awards, the incurrence of contract costs, contract cost estimation, and unit
deliveries. See Critical Accounting Policies, Estimates, and Judgments - Revenue Recognition in Item 7.

Backlog

As of December 31, 2018 and 2017, our total backlog was approximately $23 billion and $21 billion, respectively.
We expect approximately 30% of backlog at December 31, 2018, to be converted into sales in 2019.

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 ("IDIQ") 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. For long-term contracts, we generally obtain price quotations for many
of our material 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.

Governmental Regulation and Supervision

Our business is affected by a variety of laws and regulations relating to the award, administration, and performance
of U.S. Government contracts. See Risk Factors in Item 1A.

We operate in a heavily regulated environment 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, government property management systems,
estimating systems, earned value management systems, and material management accounting 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 determined to be unallowable or improperly
allocated to a specific contract will not be recovered or must be refunded if already reimbursed.

The U.S. Government has the ability, pursuant to regulations relating to contractor business systems, to decrease
or withhold contract payments if it determines significant deficiencies exist in one or more such systems. In
February 2018, we received the findings of an audit conducted by the DCAA citing potentially significant
deficiencies in our Newport News segment's business system for material management. We submitted a response
in June 2018, agreeing in part and disagreeing in part with the audit findings, and we and the U.S. Government
continue to engage in discussions regarding the accuracy and significance of the DCAA’s findings. In the event the
U.S. Government makes a final determination that there are remaining significant deficiencies and that our
proposed corrective actions are inadequate, the U.S. Government may withhold up to 5% from our interim billings
on cost-reimbursement, labor-hour, and time and materials contracts at Newport News containing the contractor
business systems clause, until the U.S. Government determines all significant deficiencies have been remediated.
All U.S. Government contracts at the Newport News segment contain the relevant business systems provision, and
any related withholding 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 on 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
those 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. Termination resulting from our default could expose us to various liabilities, including excess
reprocurement 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 may 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. REAs are not considered 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.

In 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, 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 U.S. Government regulations, 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.

Our business, our contracts with various agencies of the U.S. Government, and our subcontracts with other prime
contractors are subject to a variety of laws and regulations, including, but not limited to, the Federal Acquisition
Regulation ("FAR"), the Truth in Negotiations Act, the Procurement Integrity Act, the False Claims Act, U.S. 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.

Competition

In our primary business of designing, building, overhauling, and repairing military ships, we primarily compete with
General Dynamics and, to a lesser extent, smaller shipyards, one or more of which could team with a large defense
contractor. Intense competition related to programs, resources, and funding, and long operating cycles are key
characteristics of both our 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, serve 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 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.

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. We are one
of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy, and we are
party to long-term teaming agreements with the other company for the production of 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 of ships as well.

Our success in the shipbuilding defense industry depends upon our ability to develop, market, and produce our
products and services at costs consistent with the U.S. Navy's budget, 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.

We compete with a variety of companies in the provision of services to the government, energy, and oil and gas
markets.

Environmental, Health, and Safety

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 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. 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 at each site, the current state of technology, and our prior experience 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, 2018, our estimable probable future costs for environmental remediation were immaterial.
Although information gained as remediation progresses 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.

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 laws, 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.

With regard to occupational health and safety, the shipbuilding and ship repair industry includes exposure to
hazardous materials and processes. 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 two fatalities in
the past eight years. We strive to keep our Occupational Safety and Health Administration ("OSHA") compliance
programs strong.

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 40,000 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 5,800
engineers and designers and approximately 2,300 employees with advanced degrees. Our workforce contains
many third-, fourth-, and fifth-generation employees, and approximately 1,240 employees have 40 or more years of
continuous service. Employees in our shipbuilding divisions with more than 40 years of service achieve the honor of
“Master Shipbuilder.” As of December 31, 2018, we had 947 Master Shipbuilders at Newport News and 281 at
Ingalls. We employ more than 7,000 veterans across the enterprise.

More than 1,900 apprentices are trained by our two shipbuilding segments each year in more than 27 crafts and
advanced programs. From nuclear pipe welders to senior executives, we employ approximately 4,300 apprentice
school alumni, 3,000 at Newport News, 1,200 at Ingalls, and 100 at Technical Solutions.

Approximately 50% of our employees are covered by a total of nine collective bargaining agreements and two site
stabilization agreements. Newport News has four collective bargaining agreements covering represented
employees, which expire in December 2019, November 2020, November 2021, and December 2022. The collective
bargaining agreement that expires in November 2021 covers approximately 50% of Newport News employees.
Newport News craft workers employed at the Kesselring Site near Saratoga Springs, New York are represented
under an indefinite DoE site agreement. Ingalls has five collective bargaining agreements covering represented
employees, all of which expire in March 2022. Approximately 35 Technical Solutions craft employees at the Hanford
Site near Richland, Washington are represented under an indefinite DoE site stabilization agreement. We believe
our relationship with our employees is satisfactory.

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.

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 spending could have a material adverse effect on our
financial position, results of operations, or cash flows.

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. Substantially all of
our revenues in 2018 were derived from products and services sold to the U.S. Government, and we expect this to
continue in the foreseeable future. In addition, most of our backlog as of December 31, 2018, was U.S. Government
related. Our U.S. Government contracts are subject to various risks, including our customers' political and
budgetary constraints and processes, changes in customer short term and long term strategic plans, the timing of
contract awards, significant changes in contract scheduling, intense contract and funding competition, difficulty
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. 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 Congressional funding of U.S. Navy, U.S. Coast Guard, and other government
agency programs. The funding of U.S. Government programs is subject to congressional budget authorization and
appropriation processes. For certain programs, Congress appropriates funds on a fiscal year basis even though a
program may be performed over several fiscal years. Consequently, programs are often partially funded initially and
receive additional funding only as Congress makes additional appropriations. If we incur costs in excess of existing
funding on a contract, we may not 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 remains with
respect to overall levels of defense spending across the future years defense plan, and it is likely that U.S.
Government discretionary spending levels will continue to be subject to significant pressure. For additional
information relating to the U.S. defense budget, see the Business Environment section of 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 changes in customer priorities due to
changes in military strategy and planning. In response to the need for cheaper alternatives and the proliferation of
"smart weapons," future strategy reassessments by the DoD may result in decreased demand for our shipbuilding
10

programs, including our aircraft carrier programs. For the year ended December 31, 2018, our aircraft carrier
programs accounted for approximately 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.

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 on 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 those 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. 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"), cost plus award fee ("CPAF") contracts, and time and material contracts. See the Contract
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.

Of Ingalls' revenues in 2018, approximately 83% were generated from FPI contracts, approximately 9% were
generated from CPFF contracts, approximately 5% were generated from CPAF contracts, and approximately 3%
were generated from FFP contracts. Of Newport News' 2018 revenues, approximately 40% were generated from
FPI contracts, approximately 37% were generated from CPFF contracts, and approximately 23% were generated
from CPIF contracts. Of Technical Solutions' revenues in 2018, approximately 31% were generated from CPFF
contracts, approximately 29% were generated from FFP contracts, approximately 26% were generated from time
and material contracts, approximately 9% were generated from FPI contracts, approximately 3% were generated
from CPIF contracts, and approximately 2% were generated from CPAF 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 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, 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 satisfy 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 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 recovery risk. 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 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 connection with 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 defense industry has experienced, and we expect will continue to experience, significant changes to business
practices resulting from greater DoD focus on affordability, efficiencies, business systems, recovery of costs, and a
reprioritization of available defense funds to key areas for future defense spending. The DoD continues to adjust its
procurement practices, requirements criteria, and source selection methodology in an ongoing effort to reduce
costs, gain efficiencies, and enhance program management and control. We expect DoD's focus on business
practices to impact the contracting environment in 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 could have an impact on our current programs, as well as new business
opportunities with the DoD. In addition to DOD's business practice initiatives, the DCMA and DCAA have
implemented cost recovery/cost savings initiatives to prioritize efforts to recover costs. 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, the thresholds for certain allowable costs, including
compensation costs, have been significantly reduced, and other thresholds are being challenged, debated, and, in
certain cases, modified. Significant changes to the thresholds for allowable 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 performance 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 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 skills 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 experience
difficulties performing our contracts and competing for 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. The longer term reduction in shipbuilding activity
by the U.S. Navy, evidenced by the reduction in fleet size from 566 ships in 1989 to 287 ships as of December 31,
2018, has resulted in workforce reductions in the industry but little infrastructure consolidation. The general result
has been fewer contracts awarded to the same fixed number of shipyards. Five major private United States
shipyards, two 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. We may in the future compete with the same and other defense
contractors to build new 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 may 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 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 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 additional performance and compliance efforts 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 and compliance costs and risks and reduce our profitability.

We are audited and reviewed on a regular basis 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 damage.

The U.S. Government also has the ability, pursuant to regulations relating to contractor business systems, to
decrease or withhold contract payments if it determines significant deficiencies exist in one or more such systems.
Under such regulations, the U.S. Government may withhold up to 5% from our interim billings on cost-
reimbursement, labor-hour, and time and materials contracts containing the contractor business systems clause,
which is a significant majority of our U.S. Government customer contracts. In February 2018, we received the
findings of an audit conducted by the DCAA citing potentially significant deficiencies in our Newport News
segment's business system for material management. We submitted a response in June 2018, agreeing in part and
disagreeing in part with the audit findings, and we and the U.S. Government continue to engage in discussions
regarding the accuracy and significance of the DCAA’s findings. In the event the U.S. Government makes a final
determination that there are remaining significant deficiencies and that our proposed corrective actions are
inadequate, the U.S. Government may withhold up to 5% from our interim billings on all U.S. Government contracts
at the Newport News segment, until the U.S. Government determines all significant deficiencies have been
remediated, which could have a material impact on the timing of our cash receipts.

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. 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 CAS.
If a determination is made that we engaged in illegal activities or we are not presently responsible, as defined under
the FAR, we may be subject to reductions 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 utilized by our customers in a variety of
environments. Problems and delays with product development or delivery of 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, 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 technologies 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 attention to respond to unforeseen
problems, 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 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.

Changes in estimates used in accounting for our contracts could affect our profitability and our overall
financial position.

Contract accounting requires judgments 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
generated 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, and Judgments in Item 7.

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, 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
could adversely affect our contract performance and, as a result, our financial results. Environmental disasters,
particularly oil spills in waterways and bodies of water used for the transport and testing of our ships, can disrupt the
timing of performance 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. See 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.

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 addition to the types of events described above, 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.

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 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 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 reasonably obtainable in the market may not be sufficient to cover 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 incurring substantial costs for 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 outcome unfavorable to us may have a material adverse
effect on our financial position, results of operations, or cash flows.

Our business could suffer if we are unsuccessful in negotiating new collective bargaining agreements.

Approximately 50% of our employees are covered by a total of nine collective bargaining agreements and two site
stabilization agreements. Newport News has four collective bargaining agreements covering represented
employees, which expire in December 2019, November 2020, November 2021, and December 2022. The collective
bargaining agreement that expires in November 2021 covers approximately 50% of Newport News employees.
Newport News craft workers employed at the Kesselring Site near Saratoga Springs, New York are represented
under an indefinite DoE site agreement. Ingalls has five collective bargaining agreements covering represented
employees, all of which expire in March 2022. Approximately 35 Technical Solutions craft employees at the
Hanford Site near Richland, Washington are represented under an indefinite DoE site stabilization agreement.

Collective bargaining agreements generally expire after three to five years and 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
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.

Changes in key estimates and assumptions, 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 significant judgment regarding 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 the 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 plans, and changes to estimates and assumptions
and differences between expected and actual returns could adversely affect the timing of those pension cost
recoveries.

Unforeseen 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. In addition, we could be affected by future laws or regulations, including those imposed in
response to concerns over climate change, other aspects of the environment, or natural resources. We expect to
incur future capital and operating costs to comply with current and future environmental laws and regulations, and
such costs could be substantial, depending on the future proliferation of environmental rules and regulations 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 various permits. To manage these materials, our
shipyards have an extensive network of aboveground 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 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.

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 incur future costs to
comply with federal and state environmental laws and regulations related to the cleanup of pollutants released into
the environment. In addition, if we are found to be in violation of 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 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, 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.

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 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. 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 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 significant incremental costs and
delays.

Our reputation and our ability to do 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 has 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
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.

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 accordance with industry compliance requirements, we face cyber security threats to
our information technology infrastructure, including threats to our and the U.S. Government's proprietary and
classified information. Advanced nation state threat actors, sophisticated cybercrime syndicates, hacktivists, and
insiders can pose significant threats to our information technology infrastructure and assets. While we have
implemented countermeasures to address the risks posed by these threats, external and internal threat actors
continuously seek ways 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 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.

Our suppliers, subcontractors, and other business partners also face cyber security and other security threats.
Although we are undertaking cooperative efforts with our customers, suppliers, subcontractors, and other business
partners to assist them with understanding the threats they face and potential cyber security countermeasures to
defend against potential cyber-attacks launched by cyber threat actors, other security threats, and business
disruptions, we rely substantially 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, security, and repair, including repairs required

by the U.S. Navy, the Nuclear Regulatory Commission, or the DoE;

• Reputational 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 handle nuclear materials could pose a health risk to humans and 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 action 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 necessitate 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 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 processes designed to achieve a desired
return or strategic objective. Business acquisitions involve estimates, assumptions, and judgments to determine
acquisition prices, which 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 associated with our existing businesses.

As of December 31, 2018, goodwill and purchased intangible assets generated from prior business acquisitions
accounted for approximately 20% 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 judgments. 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.

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 provisions or exposure to additional income tax liabilities could affect our
profitability and cash flow.

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 taxability 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 income tax laws and regulations, or their interpretation, could result in higher or lower
income tax rates or changes in the taxability of certain transactions or the deductibility of certain expenses, thereby
affecting our income tax expense and profitability. On December 22, 2017, the Tax Cuts and Jobs Act (the "Tax Act")
was signed into law. The Tax Act provided for significant changes to the U.S. Internal Revenue Code of 1986, as
amended, that impact corporations, including a reduction in the federal corporate income tax rate from 35% to 21%
and changes or limitations to certain deductions. While our accounting for provisional adjustments made in the 2017
financial statements for impacts from the Tax Act was completed in 2018, the Internal Revenue Service ("IRS") did
not issue guidance on all elements of the Tax Act in 2018. Accordingly, there remain certain elements of the Tax Act
for which we cannot determine the full effects on our financial position, results of operations, or cash flows in future
years. See Note 13: Income Taxes in Item 8.

In addition, the final results of any tax audits or related litigation could be materially different from our related
historical income tax provisions and accruals. Changes in our tax rate as a result of changes in our overall
profitability, changes in tax legislation, changes in the valuation of deferred tax assets and liabilities, changes in
differences between financial statement income and taxable income, the examination of previously filed tax returns
by taxing authorities, and continuing assessments of our tax exposures can also impact our tax liabilities and affect
our income tax expense, profitability, and cash flow.

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 of opinions among the joint venture participants may result in delayed decisions or 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, 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 significant 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. Acquisitions and investments also 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 proceedings, compliance
proceedings, claims, and investigations, which could divert financial and management resources and result in fines,
penalties, compensatory, treble or other damages, or nonmonetary 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, 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 acquire adequate insurance
in the future.

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 seeking to obtain more extensive rights in intellectual property associated with its contracts, which
could reduce our rights in intellectual property we develop and our ability to control the use of certain of our
intellectual property rights. Our intellectual property is also subject to challenge, invalidation, misappropriation, or
circumvention by third parties.

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.

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 in 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. 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 to use certain intellectual property licensed to us by third parties. In instances where third parties
have 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 on commercially reasonable terms.

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 approved
share repurchase programs are within the discretion of management and depend upon many factors, including
results of operations and capital requirements, as well as applicable law.

Our debt exposes us to certain risks.

As of December 31, 2018, we had $1.3 billion of debt under our senior notes and $1.2 billion 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 billion, 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.

In addition, the interest rate on variable rate indebtedness under the Credit Facility is based on the London
Interbank Offered Rate (“LIBOR”). LIBOR is the subject of recent national, international, and other regulatory
guidance and proposals for reform. In July 2017, the Chief Executive of the U.K. Financial Conduct Authority (the
“FCA”), which regulates LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates
for the calculation of the LIBOR benchmark after 2021. This announcement indicates that the continuation of LIBOR
on the current basis cannot and will not be guaranteed after 2021, and it appears likely that LIBOR will be
discontinued or modified by 2021. The consequences of the discontinuance of the LIBOR benchmark cannot be
entirely predicted, but could include an increase in the cost of our variable rate indebtedness.

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 Navy contracts 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 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.

There were no unresolved staff comments.

ITEM 2. PROPERTIES

Our principal properties are located in Huntsville, Alabama; San Diego, California; Broomfield, Colorado;
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.

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 48 years of the lease and
beyond.

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, 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 300,000 square feet, and an apprentice
school, which provides a four-year accredited apprenticeship program to train shipbuilders.

Technical Solutions - The properties comprising our Technical Solutions operating segment are located throughout
the United States. Our properties located in Virginia Beach, Virginia; Mayport and Panama City, Florida; San Diego,
California; Bremerton, Washington; and Honolulu, Hawaii, primarily provide fleet support services. Properties
located in Huntsville, Alabama; Fairfax, Virginia; Orlando, Florida; San Antonio, Texas; and Aberdeen and Annapolis
Junction, Maryland, primarily provide MDIS services. Properties located in Broomfield, Colorado, and Newport
News, Virginia primarily provide nuclear and environmental services. A property located in Houston, Texas provides
oil and gas services.

We believe our physical facilities and equipment are generally well maintained, in good operating condition, and
satisfactory for our current needs. While our physical facilities and equipment are adequate for our current needs,
we have initiated capital expenditure programs at our Ingalls and Newport News segments that will make us more
competitive and enable us to meet future obligations under our shipbuilding programs.

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 may have a material effect on us because of our reliance on
government contracts.

Litigation - In 2015, we received a Civil Investigative Demand from the Department of Justice ("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. In July 2014, the Republic filed a statement of defense in the arbitration denying
all our allegations and a counterclaim alleging late redelivery of the frigates, unfinished work, and breach of
warranty. In February 2018, the arbitral tribunal awarded us approximately $151 million on our claims and awarded
the Republic approximately $22 million on its counterclaims. We have filed a petition in the United States District
Court for the District of Columbia asking the court to confirm or enforce the award. No assurances can be provided
regarding the ultimate resolution of this matter.

We are party to various other claims, legal proceedings, and investigations that arise in the ordinary course of
business, including U.S. Government investigations that could result in administrative, civil, or criminal proceedings
involving us. We are a contractor with the U.S. Government, and such proceedings could therefore include
additional False Claims Act allegations against us. Although we believe that the resolution of these other claims,
legal proceedings, and investigations 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 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

OVERVIEW

Our Business

Huntington Ingalls Industries, Inc. is America’s largest military shipbuilding company and a provider of professional
services to partners in government and industry. For more than a century, our Ingalls segment in Mississippi and
Newport News segment in Virginia have built more ships in more ship classes than any other U.S. naval
shipbuilder. We also provide a range of services to the governmental, energy, and oil and gas markets through our
Technical Solutions segment. Headquartered in Newport News, Virginia, HII employs approximately 40,000 people
both domestically and internationally.

We conduct most of our business with the U.S. Government, primarily the DoD. As prime contractor, principal
subcontractor, team member, or partner, we participate in many high-priority U.S. defense 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.
Our Technical Solutions segment provides a wide range of professional services, including fleet support, MDIS,
nuclear and environmental, and oil and gas services.

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

In August 2011, the BCA established limits on U.S. Government discretionary spending, including a reduction 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, to the
extent that discretionary spending limits are exceeded, and $500 billion for non-defense discretionary spending,
including the U.S. Coast Guard.

The BBA 2018 provided sequestration relief for fiscal years 2018 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. Long-term uncertainty remains with respect to overall levels of defense spending across the future years'
defense plan, and it is likely that U.S. Government discretionary spending levels will continue to be subject to
significant pressure.

While appropriations measures that fund the DoD, DoE, and a limited number of other federal agencies have been
enacted for fiscal year 2019, appropriations to fund the balance of the federal government for fiscal year 2019 have
not been enacted and Congress and the Administration have thus far been unable to agree on funding for those
agencies. We cannot predict the impact that sequestration cuts, reprioritization of readiness and modernization
investment, or lack of appropriations to fund a portion of the U.S. Government for fiscal year 2019 may have on
funding for our individual programs. 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 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, 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 current presidential
30

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 us and the entire defense industry.

Defense Industry Overview

The United States faces a complex, uncertain, and rapidly changing national security environment. 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. America also faces an ever 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 technologies is relentless, expanding
to more 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.

We expect that execution of the DoD strategy will require an affordable balance between investments in restoring
the readiness of the current force with investments in new capabilities, technologies, and capacity to meet future
challenges. The DoD faces the additional challenge of recapitalizing equipment 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 2018 and 2019, it is unclear how sequestration
could impact programs for fiscal years 2020 and 2021. 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 released the findings of a year-long Force Structure Assessment, developed to
determine 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, the 2018 National
Defense Authorization Act included the SHIPS Act, which made it the policy of our nation to achieve a fleet size of
355 ships.

The U.S. Navy’s 2019 five-year shipbuilding plan includes 54 new ships, 12 more than the 42 ships included in the
Navy’s 2018 five-year plan and 11 more than were included in the fiscal year 2018 budget request. Similarly, the
U.S. Navy’s fiscal year 2019 30-year shipbuilding plan also increased the ship count by including 301 new ships, 47
more than the 254 ships included in the Navy’s fiscal year 2017 30-year plan.

While the force objective of 355 ships reflected in the 2016 Force Structure Assessment still pertains and has been
memorialized as national policy by the 2018 SHIPS Act, both the Congressional Research Service and
Congressional Budget Office have estimated that additional ships would need to be added to the U.S. Navy’s 30-
year plan to achieve the 355 ship objective unless the Navy extends the service lives of existing ships and
reactivates recently retired ships.

In December 2018, the U.S. Navy also released its “Design for Maintaining Maritime Superiority, Version 2.0” (the
"Design"), which expands upon a posture initially put forth in January 2016 under Version 1.0 of the Design. The
new plan calls for four specific lines of effort: strengthening naval power at and from the sea; achieving high-velocity
outcomes; strengthening the U.S. Navy team of the future; and expanding and strengthening the Navy’s Network of
Partners. Each line of effort calls for specific recommendations that are intended to make the U.S. Navy more agile,
more competitive, and tougher. As a means of strengthening naval power, the plan expresses award date goals for
several major programs, including the future frigate and large surface combatant. Other initiatives include
integrating more artificial intelligence and machine learning into warfare systems, developing and fielding a family of
directed energy weapons, as well as employment of 3D printing for replacement parts.

The shipbuilding defense industry, as characterized by its competitors, customers, suppliers, potential entrants, and
substitutes, is unique in many ways. It is heavily capital 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 an
increasingly fragile supplier base that has trended toward exclusive providers. Smaller shipyards, however, have
entered the market to build the U.S. Navy's littoral combat ship and have expressed interest in the future frigate
program.

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. Additionally,
the U.S. Navy must compete with other national priorities, including other defense activities, non-defense
discretionary spending, and entitlement programs, for a share of federal budget funding. While the impact to our
business resulting from these developments remains uncertain, they could have a material impact on current
programs, as well as new business opportunities with the DoD. See Risk Factors in Item 1A.

Program Descriptions

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,
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.

Our contracts typically fall into one of four categories: firm fixed-price, fixed-price incentive, cost-type, and time and
materials. See Note 8: Revenue.

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

• Fixed-Price Incentive Contracts - Fixed-price incentive contracts provide for reimbursement of the

contractor's allowable costs, but are subject to a cost-share limit that affects profitability. Fixed-price
incentive contracts effectively become firm fixed-price contracts once the cost-share limit is reached.

• Cost-Type Contracts - Cost-type contracts provide for reimbursement of the contractor's allowable costs

plus a fee that represents profit. Cost-type contracts generally require that the contractor use its reasonable
efforts to accomplish the scope of the work within some specified time and some stated dollar limitation.

• Time and Materials - Time and materials contracts specify a fixed hourly billing rate for each direct labor

hour expended and reimbursement for allowable material costs and expenses.

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

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

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
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. We
consider our policies relating to the following matters to be critical accounting policies:

• Revenue recognition;

• Purchase accounting, goodwill, and intangible assets;

•

Litigation, commitments, and contingencies;

• Retirement related benefit plans; and

• Workers' compensation.

Revenue Recognition

Effective January 1, 2018, we adopted the requirements of Accounting Standards Update ("ASU") 2014-09,
Revenue from Contracts with Customers (Topic 606), and related amendments. Prior to January 1, 2018, we
recognized revenue in accordance with Accounting Standards Codification Topic 605-35 Construction-Type and
Production-Type Contracts utilizing the cost-to-cost measure of the percentage-of-completion method of
accounting, primarily based upon total costs incurred, with incentive fees included in sales when the amounts could
be reasonably determined and estimated. Amounts representing change orders, claims, requests for equitable
adjustment, or limitations of funding were included in sales only when they could be reliably estimated and
realization was probable. For services contracts not associated with the design, development, manufacture, or
modification of complex equipment, revenues were recognized upon delivery or as services are rendered once
persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectability is reasonably
assured. Costs related to these contracts were expensed as incurred. For additional information on the new
standard and the impact to our results of operations, refer to Note 3: Accounting Standards Updates in Item 8.

Most of our revenues are derived from long-term contracts for the production of goods and services provided to
the U.S. Government, which are generally accounted for by recognizing revenues over time using a cost-to-cost
measure of progress. The use of the cost-to-cost method to measure performance progress over time is
supported by clauses in the related contracts that allow the customer to unilaterally terminate the contract for
convenience, pay us for costs incurred plus a reasonable profit, and take control of any work in process.

When the customer is not a U.S. Government entity, we 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 we determine that revenue should be recognized over time, we utilize a measure of progress that best
depicts the transfer 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 we satisfy our
performance obligations. Accordingly, we recognize revenue over time using the cost-to-cost method to measure
performance progress. We may, however, utilize a measure of progress other than cost-to-cost, such as a labor-
based measure of progress, if the terms and conditions of the arrangement require such accounting.

unexpected waste, or inefficiencies. In these cases, we adjust our 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 our performance under the contract.

In addition, for time and material arrangements, we often utilize the practical expedient allowing the recognition of
revenue in the amount we invoice, which corresponds with the value provided to the customer and to which we
are 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 expected cost plus a margin at contract inception, which is generally the
price disclosed in the contract. Contracts are often 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 an adjustment to revenue on a cumulative catch-up basis. Alternatively, in instances in which the
performance obligations in the modifications are deemed distinct, contract modifications are accounted for
prospectively.

The amount of revenue recognized as we satisfy performance obligations associated with contracts with customers
is based upon the determination of transaction price. Transaction price reflects the amount of consideration to which
we expect to be entitled for performance under the terms and conditions of the relevant contract and may reflect
fixed and variable components, including shareline incentive fees whereby the value of the contract is variable
based upon 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 our estimated cost to complete for each period. We generally
utilize a most likely amount approach to estimate variable consideration. In all such instances, the estimated
revenues represent those amounts for which we believe a significant reversal of revenue is not probable.

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

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 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 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 estimates to complete.

For the years ended December 31, 2018, 2017, and 2016, favorable and unfavorable cumulative catch-up
adjustments were as follows:

For the year ended December 31, 2018, favorable cumulative catch-up adjustments were related to risk retirement
on the Virginia class (SSN 774) submarine program, the Legend class NSC program, USS Portland (LPD 27), and
Fort Lauderdale (LPD 28), as well as other individually insignificant adjustments. During the same period,
unfavorable cumulative catch-up adjustments were related to the Virginia class (SSN 774) submarine program,
including lower performance on Delaware (SSN 791) and Montana (SSN 794), and other individually insignificant
adjustments.

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), USS 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, USS 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 USS Gerald R. Ford (CVN 78), 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 a provision for the entire loss on the
performance obligation in the period the loss is determined.

Purchase Accounting, Goodwill, and Intangible Assets

Goodwill - Goodwill represents the purchase price paid in excess of the fair value of identifiable net tangible and
intangible assets acquired in a business combination. The amount of our goodwill as of December 31, 2018 and
2017, was $1,263 million and $1,217 million, respectively. During the year ended December 31, 2017, we 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 Holding Corporation ("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 compare 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
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. Changes in these estimates and assumptions could
materially affect the determination of fair value and/or goodwill impairment for each reporting unit.

November 30, 2018 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, 2018.

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.

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

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, 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 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 - 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 as of each of December 31, 2018 and 2017, were immaterial. See Note
2: Summary of Significant Accounting Policies 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 activities to be performed in the future, that were not reasonably
estimable as of December 31, 2018, 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/or asset decommissioning of facilities currently in use 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 - Uncertain tax positions meeting the more-likely-than-not recognition threshold, based on
the merits of the position, are recognized in the financial statements. 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 uncertain tax positions are recognized as a component of income tax expense. See Note
13: Income Taxes in Item 8. Changes in accruals associated with uncertain tax positions are recorded in earnings in
the period they are determined.

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 loss
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 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
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 within
segment operating income and non-operating retirement benefit (expense) as required by a new accounting
standard. For additional information on the new standard and the impact to our results of operations, refer to Note
3: Accounting Standards Updates in Item 8.

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, 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 in the form of higher interest rate assumptions that were
used to determine 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 The Bipartisan Budget Act of 2015 successively provided for the continuation of pension relief and higher
interest rate assumptions used to determine minimum funding requirements and extended the 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 of contributions to make to our plans each year.

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 qualified 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, 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' 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 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 4.34% and
3.82% as of December 31, 2018 and 2017, respectively. Our weighted average discount rate for other
postretirement benefits was 4.33% and 3.85% as of December 31, 2018 and 2017, 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 assumption is based more on long-term prospective views to avoid
short-term market influences. Unless plan assets and benefit obligations are subject to remeasurement 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 2018 pension expense, and we anticipate
retaining that assumption throughout 2019.

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
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 2018, the actual return on assets was
approximately minus 6.4%, which was less than the expected return assumption of 7.25%. For the year ended

December 31, 2018, the weighted average discount rates for our pension and other postretirement benefit plans
increased by 52 and 48 basis points, respectively. These differences in asset returns and discount rates resulted in
an actuarial loss of $827 million and an actuarial gain of $538 million, respectively, for the year ended
December 31, 2018.

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:

25 basis point decrease in discount rate

Assuming a 7.25% expected return on assets assumption, a $50 million pension contribution is generally expected
to favorably impact the current year expected return on assets by approximately $1 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 to 10 years for actuarial gains and losses beginning in 2013. 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 2018 was a net benefit of $364 million. The favorable change from 2017 to 2018 was
primarily driven by more immediate recognition of the 2017 asset gains under FAS and the impacts of lower
discount and interest rates and other experience gains and losses and assumptions changes (e.g. mortality). 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 driven by the final phase-in of Harmonization. Our projected 2019 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
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 value 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 17: Employee Pension and Other Postretirement Benefits,
in Item 8.

Accumulated Other Comprehensive Loss - 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 loss along with unrecognized prior service costs arising
from plan amendments. As disclosed in Note 17: Employee Pension and Other Postretirement Benefits in Item 8,
net pre-tax unrecognized actuarial losses as of December 31, 2018 and 2017 were $1,692 million and $1,459
million, respectively. The increase in these actuarial losses in 2018 was primarily driven by actual asset returns,
which were $827 million below expected returns, $78 million of amortization of previously unrecognized actuarial
losses, and a $538 million actuarial gain due to the increase in the discount rates used to determine benefit
obligations.

Net pre-tax unrecognized prior service costs (credits) as of December 31, 2018 and 2017 were $46 million and $47
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 2018
primarily resulted from amendments within a collective bargaining agreement, offset by 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 claims and an estimated accrual for claims incurred but not
reported. Our workers' compensation liability was discounted at 2.89% and 2.35% as of December 31, 2018 and
2017, respectively, based on future payment streams and a risk-free rate. We estimate a 100 basis points increase
or decrease in the discount rate would change our workers' compensation liability by $(32) million or $38 million,
respectively. The workers' compensation benefit obligation on an undiscounted basis was $845 million and $925
million as of December 31, 2018 and 2017, respectively.

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.

2018 - Cost of product sales in 2018 increased $350 million, or 8%, compared to 2017. Cost of product sales at our
Ingalls segment increased $171 million in 2018, primarily as a result of the volume changes described above, lower
risk retirement on Tripoli (LHA 7) and the Legend class NSC program, and one time employee bonus payments in
2018 related to the Tax Act. Cost of product sales at our Newport News segment increased $264 million in 2018,
primarily as a result of the volume changes described above, lower risk retirement in the Virginia class (SSN 774)
submarine program, and one time employee bonus payments in 2018 related to the Tax Act. Cost of product sales
at our Technical Solutions segment decreased $23 million in 2018, primarily due to the lower volumes described
above and an allowance for accounts receivable in 2017 on a nuclear and environmental commercial contract. Cost
of product sales related to the Operating FAS/CAS Adjustment decreased $62 million from 2017 to 2018.

Cost of product sales as a percentage of product sales increased from 76.7% in 2017 to 76.8% in 2018, primarily
due to lower risk retirement on Tripoli (LHA 7), the Virginia class (SSN 774) submarine program, and the Legend
class NSC program, as well as one time employee bonus payments in 2018 related to the Tax Act, offset by a
favorable change in the Operating FAS/CAS Adjustment, an allowance for accounts receivable on a nuclear and
environmental commercial contract in 2017, and year-to-year variances in contract mix.

2017 - Cost of product sales in 2017 increased $40 million, or 1%, compared to 2016. Cost of product sales at our
Ingalls segment increased $64 million in 2017, 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). Cost of product sales at our Newport
News segment increased $56 million in 2017, 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 retirement in the Virginia class (SSN 774) submarine program. Cost of product sales at
our Technical Solutions segment decreased $56 million in 2017, primarily due to the resolution in 2016 of
outstanding contract changes on a nuclear and environmental commercial contract, partially offset by the
establishment of an allowance for accounts receivable on a nuclear and environmental commercial contract in
2017. Cost of product sales related to the Operating FAS/CAS Adjustment decreased $24 million from 2016 to
2017.

Cost of product sales as a percentage of product sales increased from 75.2% in 2016 to 76.7% 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), a favorable change in the Operating FAS/CAS
Adjustment, and the resolution of outstanding contract changes on the RCOH of the redelivered USS Abraham
Lincoln (CVN 72).

Cost of Service Revenues

2018 - Cost of service revenues in 2018 increased $222 million, or 14%, compared to 2017. Cost of service
revenues at our Ingalls segment decreased $3 million in 2018, primarily as a result of the volume changes
described above. Cost of service revenues at our Newport News segment increased $244 million in 2018, primarily
as a result of the higher sales volumes described above. Cost of service revenues at our Technical Solutions
segment increased $4 million in 2018, primarily due to one time employee bonus payments in 2018 related to the
Tax Act. Cost of service revenues related to the Operating FAS/CAS Adjustment decreased $23 million from 2017 to
2018.

Cost of service revenues as a percentage of service revenues decreased from 82.2% in 2017 to 81.7% in 2018,
primarily driven by the resolution in 2017 of outstanding contract changes on the inactivation of the
decommissioned Enterprise (CVN 65) and one time employee bonus payments in 2018 related to the Tax Act,
partially offset by a favorable change in the Operating FAS/CAS Adjustment and year-to-year variances in contract
mix.

2017 - Cost of service revenues in 2017 increased $328 million, or 27%, compared to 2016. Cost of service
revenues at our Ingalls segment increased $23 million in 2017, primarily as a result of the higher sales volumes
described above. Cost of service revenues at our Newport News segment increased $30 million in 2017, primarily
as a result of the higher sales volumes described above. Cost of service revenues at our Technical Solutions
segment increased $293 million in 2017, primarily as a result of the higher volumes described above. Cost of
service revenues related to the Operating FAS/CAS Adjustment decreased $18 million from 2016 to 2017.

Cost of service revenues as a percentage of service revenues decreased from 84.1% in 2016 to 82.2% in 2017,
primarily driven by a favorable change in the Operating FAS/CAS Adjustment, the resolution of outstanding contract
changes on the inactivation of the decommissioned Enterprise (CVN 65), improved performance in oil and gas
services, and year-to-year variances in contract mix.

Income 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.

2018 - Income from operating investments, net increased $5 million, or 42%, to $17 million in 2018 from $12 million
in 2017. The increase resulted from higher equity income from our SRNS and N3B investments.

2017 - Income from operating investments, net increased $6 million, or 100%, to $12 million in 2017 from $6 million
in 2016. The increase resulted from higher equity income from our SRNS investment.

Other Income and Gains

2018 - Other income and gains increased $14 million in 2018 compared to 2017, primarily as a result of recoveries
related to a settlement agreement at our Ingalls segment.

2017 - Other income and gains decreased $15 million in 2017 compared to 2016. The decrease resulted from state
and local government grants at our Newport News segment in 2016.

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.

2018 - General and administrative expenses in 2018 increased $112 million, or 15%, compared to 2017. This
increase was primarily driven by higher overhead costs related to increased headcount, as well as higher current
state income tax expense, partially offset by lower non-current state income tax expense.

2017 - General and administrative expenses in 2017 decreased $9 million, or 1%, compared to 2016. This
decrease was primarily driven by lower overhead costs, partially offset by higher non-current state income tax
expense.

Operating Income

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

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

2018 - Segment operating income in 2018 was $663 million, compared to $688 million in 2017. The decrease was
primarily due to lower performance in the Virginia class (SSN 774) submarine program, lower risk retirement on
Tripoli (LHA 7) and the Legend class NSC program, the resolution in 2017 of outstanding contract changes on the
inactivation of the decommissioned Enterprise (CVN 65) and the RCOH of USS Abraham Lincoln (CVN 72), as well
as one time employee bonus payments in 2018 related to the Tax Act, partially offset by favorable changes in
workers' compensation expense, recoveries related to a settlement agreement at our Ingalls segment and an
allowance for accounts receivable in 2017 on a nuclear and environmental commercial contract.

2017 - Segment operating income in 2017 was $688 million, compared to $715 million in 2016. The decrease was
primarily due to lower risk retirement on the delivered USS John P. Murtha (LPD 26), lower volume and risk
retirement in the Virginia class (SSN 774) submarine program and Arleigh Burke class (DDG 51) destroyers,
favorable changes in overhead costs 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, partially offset by higher risk retirement on Tripoli (LHA 7) and USS Portland (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), and improved performance in oil and gas services.

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

FAS/CAS Adjustment and Operating FAS/CAS Adjustment

The FAS/CAS Adjustment reflects the difference between expenses for pension and other postretirement benefits
determined in accordance with GAAP 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 assets, amortization of prior service cost (credit) and actuarial
loss (gain), and settlement and curtailment effects.

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

2018 - The Operating FAS/CAS Adjustment in 2018 was a net benefit of $290 million, compared to a net benefit of
$205 million in 2017. The favorable change was primarily driven by impacts of lower discount and interest rates.

2017 - The Operating FAS/CAS Adjustment in 2017 was a net benefit of $205 million, compared to a net benefit of
$163 million in 2016. The favorable change was primarily driven by the finalization of Harmonization.

We expect the FAS/CAS Adjustment in 2019 to be a net benefit of approximately $159 million ($139 million FAS
and $298 million CAS), primarily driven by the more immediate recognition of the 2018 asset loss under FAS and
the more immediate recognition of higher interest rates under CAS.

We expect the Operating FAS/CAS Adjustment in 2019 to be a net benefit of approximately $147 million ($151
million FAS and $298 million CAS), primarily driven by the more immediate recognition of higher interest rates
under CAS. The expected FAS/CAS Adjustment is subject to change during 2019, 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 uncertain tax positions 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.

2018 - Non-current state income tax expense in 2018 was $2 million, compared to $12 million in 2017. The
decrease in non-current state income tax expense was driven by a decrease in deferred state income tax expense
primarily attributable to changes in pension related adjustments.

2017 - Non-current state income tax expense in 2017 was $12 million, compared to $2 million in 2016. Deferred
state income tax expense in 2017 was $12 million, compared to deferred state income tax expense of $8 million in
2016. The increase in deferred state income tax expense was primarily attributable to changes 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.

Interest Expense

2018 - Interest expense in 2018 was $58 million, compared to $94 million in 2017. The decrease was primarily a
result of a loss from the early extinguishment of debt in 2017 from refinancing our 5.000% senior notes due in 2021
with 3.483% senior notes due in 2027. See Note 14: Debt in Item 8.

2017 - Interest expense in 2017 was $94 million, compared to $74 million in 2016. The increase was primarily a
result of a loss from the early extinguishment of debt in the fourth quarter of 2017. See Note 14: Debt in Item 8.

Non-Operating Retirement Benefit (Expense)

The non-operating retirement benefit (expense) 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.

2018 - The favorable change in the non-operating retirement benefit (expense) of $90 million from 2017 to 2018
was primarily driven by favorable 2017 returns on plan assets.

2017 - The favorable change in the non-operating retirement benefit (expense) from 2016 to 2017 was $2 million.

Federal and Foreign Income Taxes

2018 - Our effective tax rate on earnings from continuing operations was 13.9% in 2018, compared to 38.0% in
2017. The decrease in our effective tax rate for 2018 is primarily attributable to the reduction in the federal
corporate income tax rate and claims for higher research and development tax credits for prior tax years. In
addition, the 2017 effective tax rate was impacted by the revaluation of the net deferred tax assets resulting from
the decrease in the federal income tax rate included in the Tax Act.

2017 - Our effective tax rate on earnings from continuing operations was 38.0% in 2017, compared to 26.9% in
2016. The increase in our effective tax rate for 2017 was primarily attributable to the revaluation of net deferred tax
46

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 our 2018 expected discretionary pre-tax pension
contributions. See Note 13: Income Taxes in Item 8.

KEY SEGMENT FINANCIAL MEASURES

Sales and Service Revenues

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

Segment Operating Income

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 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.

2018 - Ingalls revenues, including intersegment sales, increased $187 million, or 8%, in 2018 compared to 2017,
primarily driven by higher revenues in amphibious assault ships, partially offset by lower revenues in surface
combatants and the Legend class NSC program. Amphibious assault ships revenues increased as a result of higher
volumes on Richard M. McCool Jr. (LPD 29), Bougainville (LHA 8), and Fort Lauderdale (LPD 28), partially offset by
lower volumes on the delivered USS Portland (LPD 27) and Tripoli (LHA 7). Surface combatants revenues
decreased due to lower volumes on the delivered USS Ralph Johnson (DDG 114), Lenah H. Sutcliffe Higbee (DDG
123), Paul Ignatius (DDG 117), and the delivered USS John Finn (DDG 113), partially offset by higher volumes on
USS Fitzgerald (DDG 62) repair and restoration, Jack H. Lucas (DDG 125), and Ted Stevens (DDG 128).
Revenues on the Legend class NSC program decreased due to lower volume on USCGC Kimball (NSC 7) and
Midgett (NSC 8), as well as lower risk retirement across the NSC program, partially offset by higher volumes on
Stone (NSC 9) and NSC 10 (unnamed).

2017 - Ingalls revenues, including intersegment sales, increased $31 million, or 1%, in 2017 compared to 2016,
primarily driven by higher revenues in amphibious assault ships, partially offset by lower revenues in surface
combatants and the Legend class NSC program. Amphibious assault ships revenues increased as a result of higher
volumes on Bougainville (LHA 8) and Fort Lauderdale (LPD 28), partially offset by lower volume on the delivered
USS John P. Murtha (LPD 26) and USS Portland (LPD 27). Surface combatants revenues decreased due to lower
volumes on the delivered USS John Finn (DDG 113), Ralph Johnson (DDG 114), Frank E. Petersen Jr. (DDG 121),
Paul Ignatius (DDG 117), and Delbert D. Black (DDG 119), partially offset by higher volumes on Lenah H. Sutcliffe
Higbee (DDG 123), Jack H. Lucas (DDG 125), and the extended selected restricted availability contract for USS
Ramage (DDG 61). Revenues on the Legend class NSC program decreased due to lower volume on the delivered
USCGC Munro (NSC 6), partially offset by higher volumes on Stone (NSC 9) and Midgett (NSC 8).

Segment Operating Income

2018 - Ingalls operating income remained stable from 2017 to 2018 at $313 million, as recoveries related to a
settlement agreement, higher risk retirement on Arleigh Burke class (DDG 51) destroyers, and the higher volumes
described above were offset by lower risk retirement on Tripoli (LHA 7) and the Legend class NSC program.

2017 - Ingalls operating income in 2017 was $313 million, compared to income of $321 million in 2016. The
decrease was primarily due to lower risk retirement on the delivered USS John P. Murtha (LPD 26) and Arleigh
Burke class (DDG 51) destroyers, partially offset by higher risk retirement on Tripoli (LHA 7) and USS Portland
(LPD 27).

Sales and Service Revenues

2018 - Newport News revenues, including intersegment sales, increased $558 million, or 13%, in 2018 compared to
2017, primarily driven by higher revenues in aircraft carriers and naval nuclear support services, partially offset by
lower revenues in submarines. Aircraft carriers revenues increased primarily as a result of higher volumes on the
execution contract for the RCOH of USS George Washington (CVN 73) and the advance planning contract for
Enterprise (CVN 80), partially offset by lower volumes on the inactivation of the decommissioned aircraft carrier
Enterprise (CVN 65) and the execution contract for the RCOH of the redelivered USS Abraham Lincoln (CVN 72).
Naval nuclear support services revenues increased primarily as a result of higher volumes in submarine support
and facility maintenance services. Submarines revenues related to the Virginia class (SSN 774) submarine program
decreased due to lower volumes and performance on Block III boats, partially offset by higher volumes on Block IV
and Block V boats.

2017 - Newport News revenues, including intersegment sales, increased $75 million, or 2%, in 2017 compared to
2016, primarily driven by higher revenues in aircraft carriers and naval nuclear support services, partially offset by
lower revenues in submarines. Aircraft carriers revenues increased primarily as a result of higher volumes on the
advance planning and execution contract for the RCOH of USS George Washington (CVN 73), the construction
contract for John F. Kennedy (CVN 79), and the advance planning contract for Enterprise (CVN 80), partially offset
by lower volumes on the execution contract for the RCOH of the redelivered USS Abraham Lincoln (CVN 72), the
construction contract for the delivered USS Gerald R. Ford (CVN 78), and the inactivation of the decommissioned
Enterprise (CVN 65). Naval nuclear support services revenues increased primarily as a result of higher volumes in
submarine support and facility maintenance services, partially offset by lower volumes in aircraft carrier support
services. Submarines revenues related to the Virginia class (SSN 774) submarine program decreased due to lower
volumes on Block III boats, partially offset by higher volumes on Block IV boats.

Segment Operating Income

2018 - Newport News operating income in 2018 was $318 million, compared to income of $354 million in 2017. The
decrease was primarily due to lower performance in the Virginia class (SSN 774) submarine program, including
Delaware (SSN 791) and Montana (SSN 794), the resolution in 2017 of outstanding contract changes on the
inactivation of the decommissioned Enterprise (CVN 65) and the RCOH of USS Abraham Lincoln (CVN 72), as well
as one time employee bonus payments in 2018 related to the Tax Act, partially offset by favorable changes in
workers' compensation expense and the increased volume described above.

2017 - Newport News operating income in 2017 was $354 million, compared to income of $386 million in 2016. The
decrease was primarily due to lower volume and risk retirement in the Virginia class (SSN 774) submarine program,
favorable changes in overhead costs in 2016, and the receipt in 2016 of a local government incentive grant, partially
offset by 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).

2018 - Technical Solutions revenues, including intersegment sales, for the year ended December 31, 2018,
increased $36 million, or 4%, compared to 2017, primarily due to higher revenues in oil and gas services and MDIS
services, partially offset by lower nuclear and environmental and fleet support revenues.

2017 - Technical Solutions revenues, including intersegment sales, for the year ended December 31, 2017,
increased $261 million, or 38%, compared to 2016, primarily due to higher volume in MDIS services following the

December 2016 acquisition of Camber and higher volumes in fleet support and oil and gas services, partially offset
by lower nuclear and environmental volumes due to the resolution in 2016 of outstanding contract changes on a
nuclear and environmental commercial contract.

Segment Operating Income

2018 - Operating income in the Technical Solutions segment for the year ended December 31, 2018, was $32
million, compared to operating income of $21 million in 2017. The increase was primarily due to an allowance for
accounts receivable in 2017 on a nuclear and environmental commercial contract and higher income from operating
investments at our nuclear and environmental joint ventures, partially offset by one time employee bonus payments
in 2018 related to the Tax Act and lower performance in fleet support services.

2017 - Operating income in the Technical Solutions segment for the year ended December 31, 2017, was $21
million, compared to operating income of $8 million in 2016. The increase was primarily due to improved
performance in oil and gas services and higher volume in MDIS services following the December 2016 acquisition
of Camber, partially offset by the establishment of an allowance for accounts receivable on a nuclear and
environmental commercial contract in 2017 and the resolution in 2016 of outstanding contract changes on a nuclear
and environmental commercial contract.

BACKLOG

Total backlog as of December 31, 2018, was approximately $23 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 IDIQ orders. For contracts having no stated contract values, backlog includes only the
amounts committed by the customer.

in 2019. U.S. Government orders comprised substantially all of the backlog as of December 31, 2018 and 2017.

Awards

2018 - The value of new contract awards during the year ended December 31, 2018, was approximately $9.8
billion. Significant new awards during the period included contracts for the construction of three Arleigh Burke class
(DDG 51) destroyers, for the detail design and construction of Richard M. McCool Jr. (LPD 29), for procurement of
long-lead-time material for Enterprise (CVN 80), and for the construction of NSC 10 (unnamed) and NSC 11
(unnamed).

In addition, we received awards in 2019 valued at $15.2 billion for detail design and construction of the Gerald R.
Ford class (CVN 78) aircraft carriers Enterprise (CVN 80) and CVN 81 (unnamed).

2017 - The value of new contract awards during the year ended December 31, 2017, was approximately $8.1
billion. Significant new awards during this period included the detailed design and construction contract for
Bougainville (LHA 8) and the execution contract for the RCOH of USS George Washington (CVN 73).

LIQUIDITY AND CAPITAL RESOURCES

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

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

Operating Activities

2018 - Cash provided by operating activities was $914 million in 2018, compared to $814 million in 2017. The
increase of $100 million in operating cash flow was primarily due to a change in trade working capital and lower
income tax payments, partially offset by increased funding of retiree benefit plans. The change in trade working
capital was primarily driven by the timing of payments of accounts payable.

We expect cash generated from operations in 2019, in combination with our current cash and cash equivalents, as
well as existing credit facilities, to be sufficient to service debt and retiree benefit plans, meet contractual
obligations, and finance capital expenditures for at least the next 12 months.

2017 - Cash provided by operating activities was $814 million in 2017, compared to $822 million in 2016. The
decrease of $8 million in operating cash flow was primarily due to increased funding of retiree benefit plans and the
change in deferred income taxes, partially offset by a change in trade working capital. The change in trade working
capital was primarily driven by the timing of payments of accounts payable.

Investing Activities

2018 - Cash used in investing activities was $476 million in 2018, an increase of $127 million from 2017. The
change in investing cash flow was driven by the acquisition of G2, Inc., higher capital expenditures, and
investments in nuclear and environmental joint ventures in 2018, partially offset by the proceeds from the sale of
Avondale.

For 2019, we expect our capital expenditures for maintenance and sustainment to be approximately 1.5% to 2.0%
of annual revenues and our discretionary capital expenditures to be approximately 3.5% to 4.0% of annual
revenues.

2017 - Cash used in investing activities was $349 million in 2017, a decrease of $304 million from 2016. The
change in investing cash flow was driven by the acquisition of Camber in 2016, partially offset by higher capital
expenditures in 2017.

Financing Activities

2018 - Cash used in financing activities in 2018 was $899 million, compared to $484 million used in 2017. The
change was primarily due to increases of $456 million of common stock repurchases and $17 million of cash
dividend payments, partially offset by decreases of $31 million in employee tax withholdings on share-based
payment arrangements and $27 million of debt related expenditures.

2017 - Cash used in financing activities in 2017 was $484 million, compared to $343 million used in 2016. The
change was primarily due to increases of $92 million of common stock repurchases, $27 million of debt related
expenditures, $17 million of cash dividend payments, and $5 million in employee tax withholdings on share-based
payment arrangements.

Free Cash Flow

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

2018 - Free cash flow increased $59 million from 2017, primarily due to a change in trade working capital and lower
income tax payments, partially offset by increased funding of retiree benefit plans and higher capital expenditures.

2017 - Free cash flow decreased $84 million from 2016, primarily due to increased funding of retiree benefit plans,
higher capital expenditures, and a change in trade working capital.

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. We made the following minimum and discretionary
contributions to our pension and other postretirement plans in the years ended December 31, 2018, 2017, and
2016:

We made discretionary contributions to our qualified defined benefit pension plans totaling $508 million, $294
million, and $167 million in the years ended December 31, 2018, 2017, and 2016, respectively.

As of December 31, 2018 and 2017, our qualified pension plans were funded 90% and 89%, respectively, on a FAS
basis. As of December 31, 2018 and 2017, 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 2019
cash contributions to our qualified defined benefit pension plans to be $21 million, all of which we anticipate will be
discretionary and which are exclusive of CAS cost recoveries in 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 contributions were $30 million, $34 million, and $32 million in 2018, 2017, and 2016,
respectively. We expect our 2019 contributions to our other postretirement benefit plans to be approximately $33
million, which are exclusive of CAS cost recoveries in our contracts. Contributions for postretirement benefits are
not required to be funded in advance and are paid on an as-incurred basis.

Other Sources and Uses of Capital

Stockholder Distributions - In November 2018, our board of directors authorized an increase in our quarterly cash
dividend to $0.86 per share. The board previously increased the quarterly cash dividend to $0.72 per share in
November 2017 and $0.60 per share in November 2016. We paid cash dividends totaling $132 million ($3.02 per
share), $115 million ($2.52 per share), and $98 million ($2.10 per share) in the years ended December 31, 2018,
2017, and 2016, respectively.

In November 2017, our board of directors authorized an increase in our stock repurchase program from $1.2 billion
to $2.2 billion and an extension of the term of the program from October 31, 2019, to October 31, 2022.
Repurchases are made from time to time at management's discretion in accordance with applicable federal
securities laws. For the year ended December 31, 2018, we repurchased 3,620,916 shares at an aggregate cost of
$788 million, of which $48 million was not yet settled for cash as of December 31, 2018. For the years ended
December 31, 2017 and 2016, we repurchased 1,417,808 and 1,266,192 shares, respectively, at aggregate costs
of $288 million and $192 million, respectively, of which $2 million for the year ended December 31, 2017, was not
yet settled for cash as of December 31, 2017.

Additional Capital - In December 2017, we issued $600 million aggregate principal amount of 3.483% senior notes
due December 2027, the net proceeds of which were used to repurchase our 5.000% senior notes due in 2021. In
November 2015, we issued $600 million aggregate principal amount of unregistered 5.000% senior notes due
November 2025, the net proceeds of which were used to repurchase our 7.125% senior notes due in 2021. Interest
on our senior notes is payable semi-annually.

In November 2017, we terminated our Second Amended and Restated Credit Agreement with third-party lenders
and entered into a new Credit Agreement (the "Credit Facility") with third-party lenders. The Credit Facility includes
a revolving credit facility of $1,250 million, which may be drawn upon during a period of five years from November
22, 2017. The revolving credit facility includes a letter of credit subfacility of $500 million. The revolving credit facility
has a variable interest rate on outstanding borrowings based on the London Interbank Offered Rate ("LIBOR") plus
a spread based upon our credit rating, which may vary between 1.125% and 1.500%. The revolving credit facility

also has a commitment fee rate on the unutilized balance based on our leverage ratio. The commitment fee rate as
of December 31, 2018 was 0.25% and may vary between 0.20% and 0.30%.

We were in compliance with all debt-related covenants as of and during the year ended December 31, 2018. For a
description of our outstanding debt amounts and related restrictive covenants, see Note 14: Debt in Item 8.

CONTRACTUAL OBLIGATIONS

As of December 31, 2018, our total outstanding long-term debt was $1,283 million, consisting of senior notes and
other third-party debt. For a description of our outstanding debt amounts and related restrictive covenants, see Note
14: Debt in Item 8.

On March 29, 2011, HII entered into a Separation and Distribution Agreement (the "Separation Agreement") with its
former parent company, Northrop Grumman Corporation ("Northrop Grumman"), and Northrop Grumman's
subsidiaries (Northrop Grumman Shipbuilding, Inc. and Northrop Grumman Systems Corporation), pursuant to
which HII was legally and structurally separated from Northrop Grumman. In connection with the spin-off from
Northrop Grumman, we also entered into a Tax Matters Agreement with Northrop Grumman (the "Tax Matters
Agreement"), which governs the respective rights, responsibilities, and obligations of Northrop Grumman and us
after the spin-off 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. As of
December 31, 2017, we were due $8 million from Northrop Grumman under spin-off related agreements, including
the Tax Matters Agreement. For the year ended December 31, 2018, we received the $8 million from Northrop
Grumman.

(1) A "purchase obligation" is defined as an agreement to purchase goods or services that is enforceable and
legally binding on us and that specifies 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
amounts are primarily comprised of open purchase order commitments to vendors and subcontractors
pertaining to funded contracts.

(2) Other long-term liabilities primarily consist of total accrued workers' compensation reserves, deferred

compensation, and other miscellaneous liabilities, of which $225 million is the current portion of workers'
compensation liabilities. It excludes obligations for uncertain tax positions of $26 million, including penalties and
interest, for which the timing of the payments, if any, cannot be reasonably estimated.

The preceding table excludes retirement related contributions. Amounts for retirement related contributions depend
on plan provisions, actuarial assumptions, actual plan asset performance, and other factors described above under
Retirement Related Benefit Plans under Critical Accounting Policies, Estimates and Judgments and under Liquidity
and Capital Resources.

Further details regarding long-term debt and operating leases can be found in Note 14: Debt and Note 16:
Commitments and Contingencies in Item 8.

Off-Balance Sheet Arrangements

In the ordinary course of business, we use standby letters of credit issued by commercial banks and surety bonds
issued by insurance companies principally to support our self-insured workers' compensation plans. As of
December 31, 2018, $16 million in standby letters of credit were issued but undrawn and $275 million of surety
bonds were outstanding.

As of December 31, 2018, we had no other significant off-balance sheet arrangements other than operating leases.
For a description of our operating leases, see Note 2: Summary of Significant Accounting Policies and Note 16:
Commitments and Contingencies in Item 8.

GLOSSARY OF PROGRAMS

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

Program Name

Program Description

America class (LHA 6) amphibious assault
ships

Carrier RCOH

Columbia class (SSBN 826) submarines

Fleet support services

Design and build large deck amphibious assault ships that

provide forward presence and power projection as an integral part
of joint, interagency and multinational maritime expeditionary
forces. The America class (LHA 6) ships, together with the Wasp
class (LHD 1) ships, are the successors to the decommissioned
Tarawa class (LHA 1) ships. The America class (LHA 6) ships
optimize aviation operations and support capabilities. We
delivered USS America (LHA 6) in April 2014, Tripoli (LHA 7) is
scheduled for delivery in 2019, and we are currently constructing
Bougainville (LHA 8).

Build guided missile destroyers designed for conducting anti-air,
anti-submarine, anti-surface, and strike operations. The Aegis-
equipped Arleigh Burke class (DDG 51) destroyers are the U.S.
Navy's primary surface combatant, and have been constructed in
variants, allowing technological advances during construction. In
2016 we delivered USS John Finn (DDG 113), and in 2017 we
delivered Ralph Johnson (DDG 114). We are constructing five
Arleigh Burke class (DDG 51) destroyers: Paul Ignatius (DDG
117), Delbert D. Black (DDG 119), Frank E. Petersen Jr. (DDG
121), Lenah H. Sutcliffe Higbee (DDG 123), and Jack H. Lucas
(DDG 125).

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

Newport News is participating in designing the Columbia class
submarine as a replacement for the current aging Ohio class
nuclear ballistic missile submarines, which were first introduced
into service in 1981. The Ohio class SSBN includes 14 nuclear
ballistic missile submarines and four nuclear cruise missile
submarines. The Columbia class program plan of record is to
construct 12 new ballistic missile submarines. The U.S. Navy has
initiated the design process for the new class of submarines, and,
in early 2017, the DOD signed the acquisition decision
memorandum approving the Columbia class program’s Milestone
B, which formally authorizes the program’s entry into the
engineering and manufacturing development phase. We perform
design work as a subcontractor to Electric Boat, and we have
entered into a teaming agreement with Electric Boat to build
modules for the entire Columbia class (SSBN 826) submarine
program that leverages our Virginia class (SSN 774) experience.
We have been awarded contracts from Electric Boat to begin
integrated product and process development and provide long-
lead-time material and advance construction for the Columbia
class (SSBN 826) program. Construction of the first Columbia
class (SSBN 826) submarine is expected to begin in 2021.

was delivered to the U.S. Navy in the second quarter of 2017. In
June 2015, we were awarded a contract for the detail design and
construction of John F. Kennedy (CVN 79), following several
years of engineering, advance construction, and purchase of
long-lead time components and material. In addition, we have
received awards for detail design and construction of Enterprise

operations and comprehensive income, changes in equity, and cash flows for each of the three years in the period
ended December 31, 2018, 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, 2018 and 2017, and the results of its
operations and its cash flows for each of the three years in the period ended December 31, 2018, 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, 2018, 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 14, 2019, 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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders 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, 2018, 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, 2018, 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, 2018,
of the Company and our report dated February 14, 2019, expressed an unqualified opinion on those financial
statements.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS

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

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

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. Additionally, certain prior year amounts have been reclassified to conform
to the current year presentation. See Note 3: Accounting Standards Updates.

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.

In August 2011, the Budget Control Act established limits on U.S. Government discretionary spending, and provided
for potential sequestration cuts to defense spending and non-defense discretionary spending. The Bipartisan
Budget Act of 2018 (the "BBA 2018") provided sequestration relief for fiscal years 2018 and 2019. Sequestration
remains in effect for fiscal years 2020 and 2021 and could result in significant decreases in DoD spending that
could negatively impact the Company's consolidated financial position, results of operations, or cash flows, as well
as its estimated recovery of goodwill and other long-lived assets.

Revenue Recognition - Effective January 1, 2018, the Company adopted the requirements of Accounting Standards
Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606), and related amendments. Prior to
January 1, 2018, the Company recognized revenue in accordance with Accounting Standards Codification Topic
605-35 Construction-Type and Production-Type Contracts utilizing the cost-to-cost measure of the percentage-of-
completion method of accounting, primarily based upon total costs incurred, with incentive fees included in sales
when the amounts could be reasonably determined and estimated. Amounts representing change orders, claims,
requests for equitable adjustment, or limitations of funding were included in sales only when they could be reliably
estimated and realization was probable. For services contracts not associated with the design, development,
manufacture, or modification of complex equipment, revenues were recognized upon delivery or as services are
rendered once persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectability is
reasonably assured. Costs related to these contracts were expensed as incurred. For additional information on the
new standard and the impact to the Company's results of operations, refer to Note 3: Accounting Standards
Updates.

Most of the Company's revenues are derived from long-term contracts for the production of goods and services
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 progress. The use of the cost-to-cost method
to measure performance progress over time is supported by clauses in the related contracts 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. The Company utilizes the cost-to-cost method to
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 transfer 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 progress 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.

The amount of revenue recognized as the Company 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 conditions of the
relevant contract and may reflect fixed and variable components, including shareline incentive fees whereby the
value of the contract is variable based upon 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 regarding risks
related to technical requirements, feasibility, schedule, and contract costs. 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 lower profit-booking rate.

The cost estimation process requires significant judgment and is based upon the professional knowledge and
experience of the Company’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
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 estimates to complete.

Changes in estimates of sales, costs, and profits on a performance obligation are recognized using the
cumulative catch-up method of accounting, which recognizes in the current period the cumulative effect of the
changes in current and prior periods. A significant change in an estimate on one or more contracts in a period
could have a material effect on the Company's consolidated financial position or results of operations 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 entire 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 are presented as receivables in the condensed 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 U.S. Government or with
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 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 as 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 net realizable value, generally using the average cost method, and costs capitalized pursuant to
applicable provisions of the Federal Acquisition Regulation ("FAR") and U.S. Cost Accounting Standards ("CAS").
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 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 years ended December 31, 2018 and 2017, the Company recognized cash grant benefits of $61 million and
$21 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 and approximately $15 million in other income and gains within the consolidated statements of
operations and comprehensive income, and recognized approximately $15 million in grant benefits in other long-
term liabilities in the consolidated statements of financial position.

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 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 uncertain tax positions 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 $25 million, $17 million,
and $19 million for the years ended December 31, 2018, 2017, and 2016, respectively. Expenses for research and
development sponsored by the customer are charged directly to the related contracts.

Environmental Costs - Environmental liabilities are accrued when the Company determines remediation costs are
probable and such costs are reasonably estimable. When only a range of costs is established and no amount within
the range is more probable than another, the minimum amount in the range is 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. As of December 31, 2018 and
2017, 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 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 $109 million and $94 million as of December 31, 2018 and 2017, respectively, and are presented within

miscellaneous other assets within the consolidated statements of financial position. These trusts consist primarily of
investments in marketable securities, which are held at fair value within Level 1 of the fair value hierarchy.

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 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. Such amounts are not material.

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. Asset retirement obligations for which the liability's fair value can be reasonably estimated were
immaterial as of December 31, 2018 and 2017.

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, 2018, 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 uncertain tax positions in the
relevant period. These amounts are recorded within operating income, while the current period state income tax
expense, which is generally 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. See Note 13: Income Taxes in Item 8.

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 were deemed necessary as of each of December 31, 2018 and 2017.

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 uncertain tax positions are recognized as a component of income tax expense. Changes
in accruals associated with uncertain tax positions 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.

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 purchased 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:

Land improvements

Buildings and improvements

Capitalized software costs

Machinery and other equipment

Years

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 borrowing rate in the assessment of lease classification as capital or
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 expenses on a straight-line
basis over the term of the lease. For purposes of recognizing lease incentives, the Company uses the date of initial
possession as the commencement date, which is generally the date on which the Company is given the right of
access to the space and begins to make improvements in preparation for the intended use.

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.

Equity Method Investments - Investments in which the Company has the ability to exercise significant influence over
the investee but does not own a majority interest or otherwise control are accounted for under the equity method of
accounting and included in other assets in its consolidated statements of financial position. The Company's equity
investments align strategically and are integrated with the Company's operations. Accordingly, the Company's share

of the net earnings or losses of the investee is included in operating income. The Company evaluates its equity
investments for other than temporary impairment whenever events or changes in business circumstances indicate
that the carrying amounts of such investments may not be fully recoverable. If a decline in the value of an equity
method investment is determined to be other than temporary, a loss is recorded in earnings in the current period.

Self-Insured Group Medical Insurance - The Company maintains a self-insured group medical insurance plan. The
plan is designed to provide a specified level of coverage for employees and their dependents. Estimated liabilities
for incurred but not paid claims utilize actuarial methods based on various assumptions, which include, but are not
limited to, HII's historical loss experience and projected loss development factors. These liabilities are recorded in
other current liabilities and account for less than 5% of the total current liabilities balance.

Self-Insured Workers' Compensation Plan - The operations of the Company are subject to federal and state
workers' compensation laws. The Company maintains self-insured workers' compensation plans and participates in
federally administered second injury workers' compensation funds. The Company estimates the liability for claims
and funding requirements on a discounted basis utilizing actuarial methods based on various assumptions, which
include, but are not limited to, the Company's historical loss experience and projected loss development factors as
compiled in an annual actuarial study. Self-insurance accruals include amounts related to the liability for reported
claims and an estimated accrual for claims incurred but not reported. The Company's workers' compensation
liability was discounted at 2.89% and 2.35% as of December 31, 2018 and 2017, respectively. These discount rates
were determined using a risk-free rate based on future payment streams. Workers' compensation benefit
obligations on an undiscounted basis were $845 million and $925 million as of December 31, 2018 and 2017,
respectively.

Litigation, Commitments, and Contingencies - Amounts associated with litigation, commitments, and contingencies
are recorded as charges to earnings when management, after taking into consideration the facts and circumstances
of each matter, including any settlement offers and projected loss or claim development factors, has determined it is
probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

Restructuring - Restructuring related accruals are reviewed and adjusted when circumstances require such a
change. Accruals for restructuring activities include estimates primarily related to facility consolidations and
closures, asset retirement obligations, long-lived asset write-downs, employment reductions, and contract
termination costs. There are no restructuring accruals or activity as of and for the years ended December 31, 2018,
2017 and 2016.

Loan Receivable - The Company holds a loan receivable in connection with a seller financed transaction involving
its previously owned Avondale Shipyard facility. The receivable is carried at amortized cost in the amount of $38
million, net of a $10 million loan discount, which approximates fair value and is recorded in miscellaneous other
assets on the consolidated statements of financial position. Interest income is recognized on an accrual basis using
the effective yield method. The discount is accreted into income using the effective yield method over the estimated
life of the loan receivable.

Retirement Related Benefit Costs - The Company accounts for its retirement related benefit plans on the accrual
basis. The measurements of obligations, costs, assets, and liabilities require significant judgment. The costs of
benefits provided by defined benefit pension plans are recorded in the period participating employees provide
service. The costs of benefits provided by other postretirement benefit plans are recorded in the period participating
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 remeasurement 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 loss 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 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 loss
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.

Related Party Transactions - On March 29, 2011, HII entered into a Separation and Distribution Agreement (the
"Separation Agreement") with its former parent company, Northrop Grumman Corporation ("Northrop Grumman"),
and Northrop Grumman's subsidiaries (Northrop Grumman Shipbuilding, Inc. and Northrop Grumman Systems
Corporation), pursuant to which HII was legally and structurally separated from Northrop Grumman. As of
December 31, 2017, the Company was due $8 million from Northrop Grumman under spin-off related agreements.
For the year ended December 31, 2018, the Company received the $8 million from Northrop Grumman. As of
December 31, 2018 and 2017, the Company had $84 million outstanding under Industrial Revenue Bonds issued
by the Mississippi Business Finance Corporation. Prior to the spin-off, repayment of principal and interest was
guaranteed by Northrop Grumman Systems Corporation. The guaranty remains in effect, and the Company has
agreed to indemnify Northrop Grumman Systems Corporation for any losses related to the guaranty.

3. ACCOUNTING STANDARDS UPDATES

Effective January 1, 2018, the Company adopted the requirements of ASU 2014-09, "Revenue from Contracts with
Customers (Topic 606)," and related amendments, which provide a single revenue recognition model under which
the Company should recognize revenue to portray the transfer of promised goods or services in a manner reflective
of the consideration the Company is entitled to receive in exchange for those goods or services. The Company
used the modified retrospective method and related practical expedient in its application of the new standard to
those contracts that were not completed as of January 1, 2018, and reflected the cumulative effect of changes in
the opening balance of retained earnings. Results for reporting periods beginning after January 1, 2018, were
presented under Topic 606, while prior period amounts were not adjusted and were reported in accordance with the
Company's historic accounting practices under Topic 605.

The adoption of Topic 606 did not have a significant impact on the Company's condensed consolidated financial
statements, contracting and accounting processes, internal controls, or information technology systems. For the
consolidated statements of operations and comprehensive income, the new standard supports the recognition of
revenue over time under the cost-to-cost input method, which is consistent with the Company’s previous revenue
recognition model for a substantial majority of its contracts. The most significant impact of the new standard was the
modification and expansion of the Company’s disclosures as they relate to revenues and contract balances. Pre-
contract fulfillment costs requiring capitalization are not material.

On the Company’s consolidated statements of financial position, contract assets and liabilities are reported in a net
position on a contract-by-contract basis at the end of each reporting period. The application of the new standard is
materially consistent with the Company’s previous accounting policies related to contract balances. In accordance
with the new standard, unbilled accounts receivable were reclassified as contract assets and advance payments
and billings in excess of revenue were reclassified as contract liabilities as of December 31, 2018 and 2017, none
of which resulted in a change to total current assets or total current liabilities. As part of the transition, the Company
also classified in contract assets approximately $64 million of retention amounts arising from contractual provisions,
since the right to collect is based on certain conditions other than the passage of time. These retention amounts
were previously reported within billed accounts receivable. Under Topic 605, the Company included warranty costs
specified in a contract as contract costs. Under Topic 606, assurance-type warranty costs are not deemed to be part
of a performance obligation and, therefore, are included within warranty liabilities, which are not material.

The adoption of Topic 606 resulted in a cumulative increase to retained earnings of $5 million, net of $1 million tax
expense, as of January 1, 2018, driven by changes in contract assets and warranty liabilities. For the year ended
December 31, 2018, each of product sales, operating income, and net earnings increased by less than $1 million
and diluted earnings per share increased by $0.01, due to the adoption of Topic 606.

In January 2016, the FASB issued ASU 2016 01, "Financial Instruments-Overall (Subtopic 825-10): Recognition
and Measurement of Financial Assets and Financial Liabilities," relating to the recognition and measurement of
financial assets and liabilities, with further clarifications made in February 2018 with the issuance of ASU 2018-03.
The amended guidance requires certain equity investments that are not consolidated and not accounted for under
the equity method to be measured at fair value, with changes in fair value recognized in net income rather than as a
component of accumulated other comprehensive loss. The Company adopted this amended guidance on January
1, 2018, using a modified retrospective transition approach, which did not have a significant impact on the
Company's condensed consolidated financial statements.

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. Additional qualitative and quantitative disclosures are required. Prior to the FASB issuing
ASU 2018-11 “Leases”, entities were required to use a modified retrospective approach upon adoption to recognize
and measure leases at the beginning of the earliest comparative period presented in the financial statements. In
July 2018, the FASB issued ASU 2018-11, which provides entities the option to initially apply ASU 2016-02 at the
adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the
period of adoption. Consequently, the comparative periods presented in the financial statements would continue to
comply with current GAAP.

The Company has completed its assessment of leasing arrangements and service contracts and the related
impacts to its business processes, internal controls, and financial statements. The Company adopted the new
standard effective January 1, 2019, using the optional transition method permitted by ASU 2018-11. The Company
elected the package of practical expedients permitted under the transition guidance within the new standard, which,
among other things, allows it to carry forward historical lease classifications. The Company also elected the
hindsight practical expedient to determine the reasonably certain lease term for existing leases. The Company's
election of the hindsight practical expedient resulted in lengthening lease terms for certain existing leases. The
Company also made an accounting policy election not to record a right-of-use asset or lease liability related to
leases with an initial term of 12 months or less. The Company recognizes those lease payments in the consolidated
statements of operations and comprehensive income on a straight-line basis over the lease term. The estimated
impact upon adoption was an increase to right-of-use assets and lease liabilities of between $200 million and $220
million with no material impact to the opening balance of retained earnings.

In January 2018, the FASB issued ASU 2018-01 Leases, “Land Easement Practical Expedient,” which permits
entities to forgo the evaluation of existing land easement arrangements to determine if they contain a lease as part
of the adoption of ASU 2016-02 issued in February 2016. Accordingly, the Company’s accounting treatment of any
existing land easement arrangements did not change. The Company adopted this standard update concurrently
with ASU 2016-02.

In March 2017, the FASB issued ASU 2017-07, "Retirement Benefits (Topic 715): Improving the Presentation of Net
Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The update requires employers to present the
service cost component of the net periodic benefit cost in the same income statement line item as other employee
compensation costs arising from services rendered during the period. 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 presented outside of any subtotal of operating income. Employers
are required 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 became effective for fiscal years
and interim periods beginning after December 15, 2017.

The Company adopted ASU 2017-07 on January 1, 2018, using the retrospective method, which changed the FAS/
CAS Adjustment within operating income, 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. Additionally, the remaining FAS/
CAS Adjustment within operating income was reclassified from general and administrative expenses to cost of
product sales and service revenues. The adoption of ASU 2017-07 did not have a material impact on the
Company's condensed consolidated statements of financial position, cash flows, accounting processes, or internal
controls.

The following table is a schedule of the impact of adoption of ASU 2017-07 for the years ended December 31, 2017
and 2016. The Company has reclassified the following line items on its previously issued consolidated financial
statements to conform to the current year presentation.

In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic
220), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which provides for
the reclassification from accumulated other comprehensive loss to retained earnings of stranded tax effects
resulting from the Tax Cuts and Jobs Act (the "Tax Act"). This update was effective for all entities for fiscal years
beginning after December 15, 2018, and interim periods within those fiscal years, and early adoption was permitted.
Effective January 1, 2018, the Company early adopted the amendments in this update and, accordingly, reclassified
the income tax effects of the Tax Act from accumulated other comprehensive loss to retained earnings. See Note
13: Income Taxes, for further disclosure.

In June 2018, the FASB issued ASU 2018-08, “Not-For-Profit Entities (Topic 958): Clarifying the Scope and the
Accounting Guidance for Contributions Received and Contributions Made,” which assists entities in evaluating the
nature and accounting treatment of contributions received. The update applies to all entities that receive
contributions of cash or other assets, but does not apply to transfers of assets from government entities to business
entities. This standard is effective for annual reporting periods beginning after December 15, 2018. The update
should be applied on a modified prospective basis. The Company is currently evaluating the impact of ASU 2018-08
on its consolidated financial statements and disclosures, accounting processes, or internal controls related to
periodic government grants received as reimbursements of costs or related to depreciable assets.

In August 2018, the FASB issued ASU 2018-13, "Changes to the Disclosure Requirements for Fair Value
Measurement," which changes the fair value measurement disclosure requirements of ASC 820. The update
includes changes to disclosures regarding valuation techniques and inputs, uncertainty, judgments, and
assumptions in fair value measurements, and how changes in fair value measurements affect performance and
cash flows. The update is effective for annual reporting periods beginning after December 15, 2019, including
interim periods therein. Early adoption is permitted for any eliminated or modified disclosures. The Company is
currently evaluating the impact of ASU 2018-13 on its consolidated financial statements and disclosures, accounting
processes, and internal controls.

In August 2018, the FASB issued ASU 2018-14, “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 is effective on a retrospective basis for fiscal years ending after
December 15, 2020, with early adoption allowed. The Company is currently evaluating the impact of ASU 2018-14
on its consolidated financial statements and disclosures, accounting processes, and internal controls.

In August 2018, the SEC issued a final rule that amends certain disclosure requirements it considers redundant,
outdated, or superseded, including disclosures related to ratio of fixed charges, changes in stockholders' equity,
dividends, and market price information. The final rule became effective in November 2018. The final rule did not
have a significant impact on the Company's consolidated financial statements and disclosures, accounting
processes, and internal controls.

Other accounting pronouncements issued but not effective until after December 31, 2018, are not expected to
have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

4. AVONDALE AND GULFPORT

In October 2014, the Company ceased shipbuilding construction operations at its Avondale, Louisiana facility. In
connection with winding down shipbuilding at this facility, the Company incurred and paid related restructuring and
shutdown costs. Pursuant to applicable provisions of the FAR and CAS for the treatment of restructuring and
shutdown related costs, the Company began amortizing the deferred costs over a five year period in 2014. In
November 2017, the U.S. Government and the Company reached a settlement to treat $251 million of these costs
as allowable costs, a majority of which were billed to the U.S. Government and collected by the end of 2018. The
settlement was consistent with management’s cost recovery expectations and did not have a material effect on the
Company’s statements of financial position or results of operations. In October 2018, the Company completed a
sale of the Avondale facility. In addition to cash proceeds, the Company financed a portion of the transaction over a
nine year period, resulting in a net gain of $7 million, recognized as a reduction to cost of sales in the fourth quarter
of 2018.

In August 2014, the Company completed closure of its Gulfport Composite Center of Excellence in Gulfport,
Mississippi. In connection with this closure, the Company incurred restructuring related costs of $54 million,
including $52 million of accelerated depreciation of fixed assets. In March 2015, the Company sold the Gulfport
Composite Center of Excellence to the Mississippi State Port Authority, resulting in a gain on disposition of $9
million, recorded as a reduction to contract costs in accordance with the terms of the Company’s contracts with the
U.S. Government. The Company reached a resolution with the U.S. Government in December 2018 regarding the
treatment and allocation of the restructuring related costs, which is substantially in accordance with management's
cost recovery expectations and does not have a material effect on the Company's consolidated financial position,
results of operations, or cash flows.

5. ACQUISITIONS

On December 3, 2018, the Company acquired G2, Inc. ("G2"), a provider of cybersecurity solutions to the U.S.
Government, for approximately $77 million in cash, net of $2 million of acquired cash. The acquisition was
consistent with the Company's strategy to optimize and expand its services portfolio. In connection with this
acquisition, the Company recorded $46 million of goodwill, which includes the value of G2's workforce, all of which
was allocated to its Technical Solutions segment, as well as $20 million of intangible assets related to existing
contract backlog. See Note 12: Goodwill and Other Intangible Assets. The Company has not completed the
purchase price allocation due to the recent acquisition date and potential adjustments upon finalization of the net
working capital adjustment and the fair values of the assets acquired and liabilities assumed. The assets, liabilities,
and results of operations of G2 are not material to the Company’s consolidated financial position, results of
operations, or cash flows.

On December 1, 2016, the Company acquired Camber Holding Corporation ("Camber"), a provider of mission-
based and information technology solutions to the U.S. Government, for approximately $369 million in cash, net of
$27 million of cash acquired. The acquisition was consistent with the Company's strategy to optimize and expand its
services portfolio. For the years ended December 31, 2018 and 2017, Camber contributed revenues of $315 million
and $309 million, respectively, and operating income of $12 million and $8 million, respectively. In connection with
76

this acquisition, the Company recorded $261 million of goodwill, all of which was allocated to its Technical Solutions
segment, primarily related to the value of Camber's workforce, and $76 million of intangible assets related to
existing contract backlog. See Note 12: Goodwill and Other Intangible Assets. For the year ended December 31,
2017, the Company recorded a goodwill adjustment of $17 million, primarily driven by the finalization of fair value
calculations for certain assets and liabilities, as well as the net working capital adjustment. The assets, liabilities,
and results of operations of Camber are not material to the Company’s consolidated financial position, results of
operations, or cash flows.

The Company funded each of these acquisitions using cash on hand. The acquisition costs incurred in connection
with these acquisitions were not material. The operating results of these businesses have been included in the
Company’s consolidated results as of the respective closing dates of the acquisitions. In allocating the purchase
prices of these businesses, the Company considered the estimated fair value of net tangible and intangible assets
acquired, with any excess purchase price recorded as goodwill. The total amount of goodwill resulting from
acquisitions expected to be deductible for tax purposes was $201 million. These acquisitions are not material either
individually or in the aggregate, and pro forma revenues and results of operations have therefore not been
provided.

6. STOCKHOLDERS' EQUITY

Common Stock - Changes in the Company's number of outstanding shares for the year ended December 31, 2018,
resulted from shares purchased in the open market under the Company's stock repurchase program and share
activity under its stock compensation plans. See Note 18: Stock Compensation Plans.

Treasury Stock - In November 2017, the Company's board of directors authorized an increase in the Company's
stock repurchase program from $1.2 billion to $2.2 billion and an extension of the term of the program from October
31, 2019, to October 31, 2022. Repurchases are made from time to time at management's discretion in accordance
with applicable federal securities laws. For the year ended December 31, 2018, the Company repurchased
3,620,916 shares at an aggregate cost of $788 million, of which $48 million was not yet settled for cash as of
December 31, 2018. For the years ended December 31, 2017 and 2016, the Company repurchased 1,417,808 and
1,266,192 shares, respectively, at aggregate costs of $288 million and $192 million, respectively, of which $2 million
for the year ended December 31, 2017, was not yet settled for cash as of December 31, 2017. The cost of
purchased shares is recorded as treasury stock in the consolidated statements of financial position.

Dividends - In November 2018, the Company's board of directors authorized an increase in the Company's
quarterly cash dividend from $0.72 per share to $0.86 per share. In November 2017, the Company's board of
directors authorized an increase in the Company's quarterly cash dividend from $0.60 per share to $0.72 per share.
In November 2016, the Company's board of directors authorized an increase in the Company's quarterly cash
dividend from $0.50 per share to $0.60 per share. The Company paid cash dividends totaling $132 million ($3.02
per share), $115 million ($2.52 per share), and $98 million ($2.10 per share) in the years ended December 31,
2018, 2017, and 2016, respectively.

Accumulated Other Comprehensive Loss - Other comprehensive income (loss) refers to gains and losses recorded
as an element of stockholders' equity but excluded from net earnings. The accumulated other comprehensive loss
as of December 31, 2018 and 2017, was comprised of unamortized benefit plan costs of $1,283 million and $906
million, respectively, and other comprehensive income (loss) items of $(5) million and $6 million, respectively.

The changes in accumulated other comprehensive loss by component for the years ended December 31, 2018,
2017, and 2016, were as follows:

exercise of stock options and vesting of restricted stock based on the treasury stock method. Under the treasury
stock method, the Company has excluded from the diluted share amounts presented above the effects of 0.3 million
Restricted Performance Stock Rights ("RPSRs") for each of the years ended December 31, 2018 and 2017. The
amounts presented above for the year ended December 31, 2016, exclude the impact of 0.1 million stock options
and 0.3 million RPSRs under the treasury stock method.

8. 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 9: Segment Information. For more detailed
information regarding the Company's significant accounting policy for revenue, see Note 2: Basis of Presentation.

U.S. Government Contracts

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

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

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

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

transfer of control to the customer.

Services - The Technical Solutions segment generates revenue primarily under U.S. Government contracts from the
provision of fleet support and MDIS services. Contracts generally are structured using either an Indefinite Delivery/
Indefinite Quantity ("IDIQ") vehicle, under which orders are issued, or a standalone contract. Contracts may be
fixed-price or cost-type, include variable consideration such as incentives and awards, and structured as task
orders under an IDIQ contract vehicle or requirements contract vehicle. In either case, the Company generally
performs over the course of a short-duration period and may continue to perform upon exercise of related period of
performance options that are also short in duration, generally one year. 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, in the case of recurring maintenance services, or a single performance obligation
that does not comprise a series of distinct services.

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

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

Non-U.S. Government Contracts

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

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

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

Disaggregation of Revenue

The following tables present revenues on a disaggregated basis, in a manner that reconciles with the Company's
reportable segment disclosures, for the following categories: product versus service type, customer type, contract
type, and major program. See Note 9: Segment Information. The Company believes that this level of disaggregation
provides investors with information to evaluate the Company’s financial performance and provides the Company
with information to make capital allocation decisions in the most appropriate manner.

As of December 31, 2018, the Company had $23.0 billion of remaining performance obligations. The Company
expects to recognize approximately 30% of its remaining performance obligations as revenue through 2019, an
additional 40% through 2021, and the balance thereafter.

Cumulative Catch-up Adjustments

For the years ended December 31, 2018, 2017, and 2016, net cumulative catch-up adjustments increased
operating income by $110 million, $204 million, and $224 million, respectively, and increased diluted earnings per
share by $1.99, $2.90, and $3.08, 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 statements of
operations and comprehensive income for the years ended December 31, 2018 and 2017.

Contract Balances

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

The Company reports contract balances in a net contract asset or contract liability position on a contract-by-contract
basis at the end of each reporting period. The Company’s net contract assets increased $59 million from
December 31, 2017 to December 31, 2018, primarily due to an increase in contract assets as a result of revenue on
certain U.S. Navy contracts. For the year ended December 31, 2018, the Company recognized revenue of $85
million related to its contract liabilities as of December 31, 2017.

9. SEGMENT INFORMATION

The Company is organized into three reportable segments: Ingalls, Newport News, and Technical Solutions,
consistent with how management makes operating decisions and assesses performance.

12. 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 tests as of November 30, 2018, 2017, and 2016,
management tested goodwill for each of its four reporting units. As a result of its annual goodwill impairment tests,
the Company determined that the estimated fair value of each reporting unit exceeded by more than 10% its
corresponding carrying value as of November 30, 2018, 2017, and 2016.

Accumulated goodwill impairment losses as of each of December 31, 2018 and 2017, were $2,877 million. The
accumulated goodwill impairment losses for Ingalls as of each of December 31, 2018 and 2017, were $1,568
million. The accumulated goodwill impairment losses for Newport News as of each of December 31, 2018 and
2017, were $1,187 million. The accumulated goodwill impairment losses for the Technical Solutions segment as of
each of December 31, 2018 and 2017, were $122 million.

For 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 years ended December 31, 2018 and 2017, the carrying amounts of goodwill changed as follows:

The Company performs tests for impairment of long-lived assets whenever events or circumstances suggest that
long-lived assets may be impaired. In connection with the G2 purchase in 2018, the Company recorded $20 million
of intangible assets pertaining to existing contract backlog and customer relationships, to be amortized using the
pattern of benefits method over a weighted-average life of seven years. In connection with the Camber purchase in
2016, the Company recorded $76 million of intangible assets pertaining to existing contract backlog and customer
relationships, to be amortized using the pattern of benefits method over a weighted-average life of 10 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 pertaining to
nuclear-powered aircraft carrier and submarine program intangible assets, with an aggregate weighted-average
useful life of 40 years based on the long life cycle of the related programs. Aggregate amortization expense for the
years ended December 31, 2018, 2017, and 2016, was $36 million, $40 million, and $23 million, respectively.

The Company expects amortization for purchased intangible assets of $37 million in 2019, $33 million in 2020, $30
million in 2021, $28 million in 2022, and $24 million in 2023.

13. INCOME TAXES

Tax Reform - The Tax Act, signed into law on December 22, 2017, significantly changed 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% to 21%, repeal of the domestic manufacturing deduction, and further
limitations on the deductibility of certain executive compensation.

The SEC staff issued Staff Accounting Bulletin 118 ("SAB 118"), which provides guidance on accounting for the
tax effects of the Tax Act in the reporting period of enactment, 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 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. To the
extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete, but the company
is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a
company cannot determine a provisional estimate to be included in the financial statements, it should continue
to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before enactment
of the Tax Act.

The Company's accounting for provisional adjustments for the following elements of the Tax Act was completed
in 2018:

Reduction of the U.S. federal corporate income tax rate: For the reduction in the federal corporate income tax
rate, the Company recorded a provisional decrease 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. In October 2018, the Company received authorization from
the Internal Revenue Service ("IRS") to change its accounting method for unbilled revenue related to service
contracts effective January 1, 2017. As a result, the Company's provisional adjustment to its net deferred tax
assets decreased by $10 million, with a corresponding reduction to deferred income tax expense of $10 million.
This adjustment was recorded in the fourth quarter of 2018, which is the period in which authorization was
received. Accounting for the reduction in the federal corporate income tax rate is now complete and resulted in
recording a total decrease to net deferred tax assets of $46 million with a corresponding increase to deferred
income tax expense.

Acceleration of depreciation: For the acceleration of depreciation for assets qualifying for immediate expensing,
the Company recorded a provisional benefit of $8 million for the year ended December 31, 2017, based on its
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 assets,
excluding the effect of the reduction in the U.S. federal corporate income tax rate, for the year ended December
31, 2017. In preparing the Company’s consolidated federal income tax return, a detailed review of capital
expenditures was completed. As a result of this analysis, the Company’s provisional benefit for asset expensing
decreased by $4 million, resulting in an increase of $4 million to current income taxes payable and a
corresponding increase in net deferred tax assets, which were recorded in the Company’s 2018 financial
statements during the fourth quarter. Accounting for the acceleration of depreciation under the Tax Act is
complete and resulted in a benefit of $4 million that decreased current income taxes payable, with a
corresponding decrease in net deferred tax assets.

The Company's accounting for the following element of the Tax Act, for which a reasonable estimate could not
be made in the 2017 financial statements, was completed in 2018:

Deductibility of executive compensation: As disclosed in the Company's Annual Report on Form 10-K for 2017, the
Company was not able to reasonably estimate the effect of the Tax Act changes to the deductibility of executive
compensation, and, therefore, no provisional adjustment was recorded. These changes included repeal of the
performance-based compensation exception to the $1 million deduction limitation of Internal Revenue Code Section
162(m) and revision of the employees subject to the $1 million deduction limitation. The only exception to this rule is
compensation 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
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 completed its
analysis of the binding contract requirement on its various compensation plans and determined the change on the
deductibility of executive compensation did not have a material effect on the Company’s 2017 financial statements.
Accordingly, no adjustment was required for this aspect of the Tax Act under ASC 740.

The IRS did not issue guidance on all elements of the Tax Act in 2018. Accordingly, there remain certain elements
of the Tax Act for which we cannot determine the full effects on our financial position, results of operations, or cash
flows in future years. However, the Company does not expect these elements to have a material effect on the
Company's financial position, results of operations, or cash flows in future years.

The Company's earnings are primarily domestic, and its effective tax rate on earnings from operations for the year
ended December 31, 2018, was 13.9%, compared with 38.0% and 26.9% for 2017 and 2016, respectively.

For the year ended December 31, 2018, the Company's effective tax rate differed from the federal statutory tax rate
primarily as a result of claims for higher research and development tax credits for prior tax years. For the year
ended December 31, 2017, the Company's effective tax rate differed from the federal statutory rate primarily as a
result of the increase in deferred federal tax expense attributable to the recalculation of the Company's net deferred
tax asset to reflect the impact of the federal income tax rate decrease included in the Tax Act, partially offset by the
income tax benefits resulting from stock award settlement activity and the domestic manufacturing deduction. For
the year ended December 31, 2016, the Company’s effective tax rate differed from the federal statutory rate
primarily as a result of the adoption of ASU 2016-09, which reduced income 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, and the domestic manufacturing deduction.

Adoption of ASU 2018-02 - The Company early adopted ASU 2018-02, "Income Statement-Reporting
Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from Accumulated Other
Comprehensive Income," which provides for the reclassification from accumulated other comprehensive loss to
retained earnings of stranded tax effects resulting from the Tax Act. In accordance with the provisions of the
ASU, $202 million of stranded tax effects related to the Tax Act were reclassified from accumulated other
comprehensive loss to retained earnings in the first quarter of 2018. This reclassification includes the impact of
the change in the federal corporate income tax rate and the related federal benefit of state taxes.

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. As of December 31,
2017, the Company was due $8 million from Northrop Grumman under spin-off related agreements, including the
Tax Matters Agreement. For the year ended December 31, 2018, the Company received the $8 million from
Northrop Grumman. The Company does not anticipate there will be any additional amounts owed between HII and
Northrop Grumman under the Tax Matters Agreement in future years.

Federal and foreign income tax expense for the years ended December 31, 2018, 2017, and 2016, consisted of the

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 ended December 31,
2018, 2017, and 2016 are summarized in the following table:

As of December 31, 2018 and 2017, the estimated amounts of the Company's uncertain tax positions, excluding
interest and penalties, were liabilities of $25 million and less than $1 million, respectively. Assuming sustainment of
these positions, as of December 31, 2018 and 2017, the reversal of $25 million and less than $1 million,
respectively, of the amounts accrued would favorably affect the Company's effective federal income tax rate in
future periods.

The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. As a
result of the unrecognized tax benefits noted above, income tax expense increased $1 million in 2018 for interest

and penalties, resulting in a liability of $1 million for interest and penalties as of December 31, 2018. In 2017, there
was a net decrease in income tax expense of $1 million 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 million for interest and penalties as of December 31, 2016. The 2016
changes in interest and penalties related to reductions in prior year tax positions and settlement with a taxing
authority.

The following table summarizes the tax years that are either currently under examination or remain open under the
applicable statute of limitations and subject to examination by the major tax jurisdictions in which the Company
operates:

Although the Company believes it has adequately provided for all uncertain tax positions, amounts asserted by
taxing 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. Conversely, the Company could settle positions
with the tax authorities for amounts lower than have been accrued. The Company believes that it is reasonably
possible that during the next 12 months the Company's liability for uncertain tax positions may decrease by $14
million due to resolution of a federal uncertain tax position.

During 2013 the Company entered into the pre-Compliance Assurance Process with the IRS for years 2011 and
2012. The Company is part of the IRS Compliance Assurance Process program for the 2014 through 2018 tax
years. Open tax years related to state jurisdictions remain subject to examination.

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% to 21% under the Tax Act, the Company revalued its net deferred tax
assets as of December 31, 2017. Net deferred tax assets are classified as long-term deferred tax assets in the
consolidated statements of financial position.

The tax effects of significant temporary differences and carry-forwards that gave rise to year-end deferred tax
balances, as presented in the consolidated statements of financial position, were as follows:

As of December 31, 2018, the Company had gross state income tax credit carry-forwards of approximately $20
million, which expire from 2019 through 2021. A deferred tax asset of approximately $15 million (net of federal
benefit) has been established related to these state income tax credit carry-forwards, with a valuation allowance of
$9 million against such deferred tax asset as of December 31, 2018. State and foreign net operating loss carry-
forwards are separately and cumulatively immaterial to the Company’s deferred tax balances and expire between
2026 and 2037.

Credit Facility - In November 2017, the Company terminated its Second Amended and Restated Credit Agreement
and entered into a new Credit Agreement (the "Credit Facility") with third-party lenders. The Credit Facility includes
a revolving credit facility of $1,250 million, which may be drawn upon during a period of five years from November
22, 2017. The revolving credit facility includes a letter of credit subfacility of $500 million. The revolving credit facility
has a variable interest rate on outstanding borrowings based on the London Interbank Offered Rate ("LIBOR") plus
a spread based upon the Company's credit ratings, which may vary between 1.125% and 1.500%. The revolving
credit facility also has a commitment fee rate on the unutilized balance based on the Company’s credit ratings. The
commitment fee rate as of December 31, 2018 was 0.25% and may vary between 0.20% and 0.30%.

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

As of December 31, 2018, approximately $16 million in letters of credit were issued but undrawn, and the remaining
$1,234 million of the revolving credit facility was unutilized. The Company had unamortized debt issuance costs
associated with its credit facilities of $8 million and $11 million as of December 31, 2018 and 2017, respectively.

Senior Notes - In December 2017, the Company issued $600 million aggregate principal amount of 3.483% senior
notes with registration rights due December 2027, the net proceeds of which were used to repurchase the
Company's 5.000% senior notes due 2021. Pursuant to the terms of the registration rights agreement entered into
in connection with the issuance of these senior notes, the Company completed in June 2018 an exchange of $600
million aggregate principal amount of registered 3.483% senior notes due December 2027 for all of the then
outstanding unregistered senior notes due December 2027. The Company also has outstanding $600 million
aggregate principal amount of unregistered 5.000% senior notes due November 2025. Interest on the Company's
senior notes is payable semi-annually.

The terms of the senior notes limit the Company’s ability and the ability of certain of its subsidiaries to create liens,
enter into sale and leaseback transactions, sell assets, and effect consolidations or mergers. The Company had
unamortized debt issuance costs associated with the senior notes of $14 million and $15 million as of
December 31, 2018 and 2017, respectively.

Early Extinguishment of Debt - Details of the loss on early extinguishment of debt related to the Company's prior
credit facility and refinancing of senior notes, which was included in interest expense, were as follows:

($ in millions)

Redemption and tender premiums and fees

Mississippi Economic Development Revenue Bonds - As of each of December 31, 2018 and 2017, the Company
had $84 million outstanding under Industrial Revenue Bonds issued by the Mississippi Business Finance
Corporation. These bonds accrue interest at a fixed rate of 7.81% per annum (payable semi-annually) and mature
in 2024.

Gulf Opportunity Zone Industrial Development Revenue Bonds - As of each of December 31, 2018 and 2017, the
Company had $21 million outstanding under Gulf Opportunity Zone Industrial Development Revenue Bonds issued
by the Mississippi Business Finance Corporation. These bonds accrue interest at a fixed rate of 4.55% per annum
(payable semi-annually) and mature in 2028.

The Company's debt arrangements contain customary affirmative and negative covenants. The Company was in
compliance with all debt covenants during the year ended December 31, 2018.

The estimated fair values of the Company's total long-term debt as of December 31, 2018, and December 31, 2017,
were $1,292 million and $1,361 million, respectively. The fair values of the Company's long-term debt were
calculated based on recent trades of the Company's debt instruments in inactive markets, which fall within Level 2
under the fair value hierarchy.

The Company does not have any principal payments due on long-term debt within the next five years.

15. 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
91

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

False Claims Act Complaint - In 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 False
Claims Act lawsuit filed under seal 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 the supplier. Depending upon the outcome of this
matter, the Company 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 its consolidated financial position, results of
operations, or cash flows. The matter remains sealed and given the current posture of the matter, the Company is
unable to estimate an amount or range of reasonably possible loss or to express an opinion regarding the ultimate
outcome.

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

Asbestos Related Claims - HII and its predecessors-in-interest are defendants in a longstanding series of cases
that have been and continue to be filed in various jurisdictions around the country, wherein former and current
employees and various third parties allege exposure to asbestos containing materials while on or associated with
HII premises or while working on vessels constructed or repaired by HII. The cases allege various injuries, including
those associated with pleural plaque disease, asbestosis, cancer, mesothelioma, and other alleged asbestos
related conditions. In some cases, several of HII's former executive officers are also named as defendants. In some
instances, partial or full insurance coverage is available to the Company for its liability and that of its former
executive officers. The cost to resolve cases during the years ended December 31, 2018, 2017, and 2016 was
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") 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, the Company filed an
arbitral statement of claim asserting breaches of the contract. In July 2014, the Republic filed a statement of
defense in the arbitration denying all the Company’s allegations and a counterclaim alleging late redelivery of the
frigates, unfinished work, and breach of warranty. In February 2018, the arbitral tribunal awarded the Company
approximately $151 million on its claims and awarded the Republic approximately $22 million on its counterclaims.
92

The Company has filed a petition in the United States District Court for the District of Columbia asking the court to
confirm or enforce the award. No assurances can be provided regarding the ultimate resolution of this matter.

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

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 unanticipated contract costs. These
estimates are based upon management's best assessment of the underlying causal events and circumstances, and
are included in contract profit margins to the extent of expected recovery based upon contractual entitlements and
the probability of successful negotiation with the customer. As of December 31, 2018, recognized amounts related
to claims and requests for equitable adjustment were not material individually or in aggregate.

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

In the ordinary course of business, the Company may guarantee obligations of its subsidiaries under certain
contracts. Generally, the Company is liable under such an arrangement 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, 2018, the Company was not aware of any existing event of default that would require it to satisfy
any of these guarantees.

Environmental Matters - The estimated cost to complete environmental remediation has been accrued when it is
probable that the Company will incur such costs in the future to address environmental conditions at currently or
formerly owned or leased operating facilities, or at sites where it has been named a Potentially Responsible Party
("PRP") by the Environmental Protection Agency or similarly designated by another environmental agency, and the
related costs can be estimated by management. These accruals do not include any litigation costs related to
environmental matters, nor do they include amounts recorded as asset retirement obligations. To assess the
potential impact on the Company's consolidated financial statements, management estimates the range of
reasonably possible remediation costs that could be incurred by the Company, taking into account currently
available facts on each site, as well as the current state of technology and prior experience remediating
contaminated sites. These estimates are reviewed periodically and adjusted to reflect changes in facts and
technical and legal circumstances. Management estimates that as of December 31, 2018, the probable estimable
future cost for environmental remediation was immaterial. Factors that could result in changes to the Company's
estimates include: modification of planned remedial actions, increases or decreases in the estimated time required
to remediate, changes to the determination of legally responsible parties, discovery of more extensive
contamination than anticipated, changes in laws and regulations affecting remediation requirements, and
improvements in remediation technology. Should other PRPs not pay their allocable share of remediation costs, the
Company may incur costs exceeding those already estimated and accrued. In addition, there are certain potential
remediation sites where the costs of remediation cannot be reasonably estimated. Although management cannot
predict whether new information gained as remediation progresses will materially affect the estimated liability
accrued, management does not believe that future remediation expenditures will have a material effect on the
Company's consolidated financial position, results of operations, or cash flows.

Financial Arrangements - In the ordinary course of business, HII uses standby letters of credit issued by commercial
banks and surety bonds issued by insurance companies primarily to support the Company's self-insured workers'
93

compensation plans. As of December 31, 2018, the Company had $16 million in standby letters of credit issued but
undrawn, as indicated in Note 14: Debt, and $275 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 HII 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.

In February 2018, the Company received the findings of an audit conducted by the Defense Contract Audit Agency
("DCAA") citing potentially significant deficiencies in the Company’s Newport News segment's business system for
material management. The Company submitted a response in June 2018, agreeing in part and disagreeing in part
with the audit findings, and the Company and the U.S. Government continue to engage in discussions regarding the
accuracy and significance of the DCAA’s findings. In the event the U.S. Government makes a final determination
that there are remaining significant deficiencies and that the Company’s proposed corrective actions are
inadequate, the U.S. Government may withhold up to 5% from the Company’s interim billings on cost-
reimbursement, labor-hour, and time and materials contracts at Newport News containing the applicable contractor
business systems clause, until the U.S. Government determines all significant deficiencies have been remediated.
All U.S. Government contracts at the Newport News segment contain the relevant business systems provision, and
any related withholding could have a material impact on the timing of the Company’s cash receipts.

Collective Bargaining Agreements - Of the Company's approximately 40,000 employees, approximately 50% are
covered by a total of nine collective bargaining agreements and two site stabilization agreements. Newport News
has four collective bargaining agreements covering represented employees, which expire in December 2019,
November 2020, November 2021, and December 2022. The collective bargaining agreement that expires in
November 2021 covers approximately 50% of Newport News employees. Newport News craft workers employed at
the Kesselring Site near Saratoga Springs, New York are represented under an indefinite Department of Energy
("DoE") site agreement. Ingalls has five collective bargaining agreements covering represented employees, all of
which expire in March 2022. Approximately 35 Technical Solutions craft employees at the Hanford Site near
Richland, Washington are represented under an indefinite DoE site stabilization agreement. The Company believes
its relationship with its employees is satisfactory.

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

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

Operating Leases - Rental expense for operating leases for the years ended December 31, 2018, 2017, and 2016,
was $69 million, $63 million, and $69 million, respectively. These amounts are net of immaterial amounts of
sublease rental income. The amounts of minimum rental commitments under long-term non-cancellable operating
leases for each of the years 2019 through 2023 and thereafter are:

17. EMPLOYEE PENSION AND OTHER POSTRETIREMENT BENEFITS

The Company provides eligible employees defined benefit pension plans and postretirement benefit 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 been 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, are 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 ended December 31, 2018, 2017, and 2016, were $102 million, $78 million,
and $71 million, respectively.

The Company also sponsors defined benefit and defined contribution pension plans to provide benefits in excess of
the tax-qualified limits. The liabilities related to these plans as of December 31, 2018, were $183 million and $30
million, respectively, and as of December 31, 2017, were $182 million and $32 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, 2018 and 2017, were $109 million
and $94 million, respectively, of which $78 million and $61 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 ended December 31,
2018, 2017, and 2016, were as follows:

The Projected Benefit Obligation ("PBO"), Accumulated Benefit Obligation ("ABO"), and asset values for the
Company's qualified pension plans were $6,336 million, $6,017 million, and $5,726 million, respectively, as of
December 31, 2018, and $6,596 million, $6,202 million, and $5,837 million, respectively, as of December 31, 2017.
The PBO represents the present value of pension benefits earned through the end of the year, with allowance for
future salary increases. The ABO is similar to the PBO, but does not provide for future salary increases.

The PBO and fair value of plan assets for all qualified and non-qualified pension plans with PBOs in excess of plan
assets were $6,519 million and $5,726 million, respectively, as of December 31, 2018, and $5,386 million and
$4,440 million, respectively, as of December 31, 2017.

The ABO and fair value of plan assets for all qualified and non-qualified pension plans with ABOs in excess of plan
assets were $6,183 million and $5,726 million, respectively, as of December 31, 2018, and $5,001 million and
$4,440 million, respectively, as of December 31, 2017. The ABO for all pension plans was $6,183 million and

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 on December 31, 2018, the Company selected an expected initial
health care cost trend rate of 5.50% and an ultimate health care cost trend rate of 4.50% to be reached in 2024. On
December 31, 2017, the Company assumed an expected initial health care cost trend rate of 6.00% and an ultimate
health care cost trend rate of 4.50% to be reached in 2025.

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
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 pension plans and other
postretirement plans for the years ended December 31, 2018, 2017, and 2016:

For the year ending December 31, 2019, the Company expects its cash contributions to its qualified defined benefit
pension plans to be $21 million, all of which will be discretionary. For the year ending December 31, 2019, the
Company expects its cash contributions to its postretirement benefit plans to be approximately $33 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, 2018. 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, 2018, as follows:

U.S. equities

International equities

Fixed income securities

Alternative investments

Range

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 allocation 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. 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 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 that use 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, reported 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, 2018, unfunded commitments to private partnerships were
$132 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.

The Company might be unable to quickly liquidate some assets at amounts close or equal to fair value in order to
meet the plans' 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.
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. The Company has credit policies and processes, which
manage concentrations of risk by seeking to undertake transactions with large well-capitalized counterparties and
by monitoring the creditworthiness of these counterparties.

100

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 master trust limits the use of derivatives through direct or separate account investments, such that the
derivatives used are liquid and able to be readily valued in the market. Derivative usage in separate account
structures is primarily for gaining market exposure in an unlevered manner or hedging investment risks. The fair
market value of the pension master trust's derivatives through direct or separate account investments resulted in a
net asset of approximately $4 million and a net liability of $1 million as of December 31, 2018 and 2017,
respectively.

There was no activity attributable to Level 3 retirement plan assets during the years ended December 31, 2018 and
2017.

18. STOCK COMPENSATION PLANS

As of December 31, 2018, HII had stock-based compensation awards outstanding under the following plans: the
Huntington Ingalls Industries, Inc. 2011 Long-Term Incentive Stock Plan (the "2011 Plan") and the Huntington
Ingalls Industries, Inc. 2012 Long-Term Incentive Stock Plan (the "2012 Plan").

Stock Compensation Plans

On March 23, 2012, the Company's board of directors adopted the 2012 Plan, subject to stockholder approval, and
the Company's stockholders approved the 2012 Plan on May 2, 2012. Award grants made on or after May 2, 2012,
were made under the 2012 Plan. Award grants made prior to May 2, 2012, were made under the 2011 Plan. No
future grants will be made under the 2011 Plan.

102

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
related to any such award. As of December 31, 2018, the remaining aggregate number of shares of the Company's
common stock authorized for issuance under the 2012 Plan was 4.0 million.

The 2011 Plan permitted the awards of stock options and other stock awards. Each stock option grant was made
with an exercise price of not less than 100% of the closing price of HII's common stock on the date of grant, with the
exception of stock options issued at the time of the spin-off in exchange for Northrop Grumman stock options. Stock
awards, in the form of stock rights, were granted to members of the board of directors without payment to the
Company.

Stock Awards

Stock awards include RPSRs, RSRs, and stock rights. The fair value of stock awards is determined based on the
closing market price of the Company's common stock on the grant date. Compensation expense for stock awards is
measured based on the grant date fair value and recognized over the vesting period, generally three years.

For purposes of measuring compensation expense, the amount of shares ultimately expected to vest is estimated
at each reporting date based on management's expectations regarding the relevant service or performance criteria.

The Company issued the following stock awards in the years ended December 31, 2018, 2017, and 2016:

Restricted Performance Stock Rights - For the year ended December 31, 2018, the Company granted
approximately 0.1 million RPSRs at a weighted average share price of $261.88. These rights are subject to cliff
vesting on December 31, 2020. For the year ended December 31, 2017, the Company granted approximately 0.1
million RPSRs at a weighted average share price of $218.54. These rights are subject to cliff vesting on December
31, 2019. For the year ended December 31, 2016, the Company granted approximately 0.2 million RPSRs at a
weighted average share price of $134.53. These rights were fully vested as of December 31, 2018. All of the
RPSRs are subject to the achievement of performance-based targets at the end of the respective vesting periods
and will ultimately vest between 0% and 200% of grant date value.

Restricted Stock Rights - Retention stock awards are granted to key employees primarily to ensure business
continuity. In 2018, the Company granted approximately 2,900 RSRs at a weighted average share price of $225.68,
with cliff vesting two to three years from the grant date. In 2017, the Company granted approximately 3,100 RSRs
at a weighted average share price of $188.13, with cliff vesting two years from the grant date. As of December 31,
2018, approximately 5,100 of these RSRs were outstanding.

For the year ended December 31, 2018, 0.2 million stock awards vested, of which approximately 0.1 million were
transferred to the Company from employees in satisfaction of minimum tax withholding obligations. For the year
ended December 31, 2017, 0.4 million stock awards vested, of which approximately 0.2 million were transferred to
the Company from employees in satisfaction of minimum tax withholding obligations. For the year ended
December 31, 2016, 0.8 million stock awards vested, of which approximately 0.3 million were transferred to the
Company from employees in satisfaction of minimum tax withholding obligations.

Stock Rights and Stock Issuances - The Company granted stock rights to its non-employee directors on a quarterly
basis in 2018, with each grant less than 10,000 shares. All stock rights granted to non-employee directors are fully
vested on the grant date. If a non-employee director has met certain stock ownership guidelines, the non-employee
director may elect under the terms of the Directors’ Compensation Policy and Board Deferred Compensation Policy
to receive their annual equity award for the following calendar year in the form of either shares of the Company’s
common stock or stock units that are payable in the fifth calendar year after the year in which the annual equity
award is earned, or, if earlier, upon termination of the director’s board service.

103

Non-employee directors may also elect to receive their annual cash retainers in the form of stock units that become
payable upon termination of the director’s board service. Non-employee directors who elect to receive their annual
cash retainers in the form of stock units and have met their stock ownership guidelines may elect under the terms of
the Directors’ Compensation Policy and Board Deferred Compensation Policy to receive stock units for the following
calendar year that are payable in the fifth calendar year after the year in which the stock units are earned, or, if
earlier, upon termination of the director’s board service.

The stock award activity for the years ended December 31, 2018, 2017, and 2016, was as follows:

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 2018, 2017, and 2016 are
based on two metrics as defined in the grant agreements: earnings before interest, taxes, depreciation,
amortization, and pension, weighted at 50%, and pension-adjusted return on invested capital, weighted at 50%.

Stock Options

Effect of the Spin-Off - Prior to the spin-off from Northrop Grumman, HII's current 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.

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,

104

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 expired 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 expired 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 ended December 31, 2018, 2017, and 2016.
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.

The stock option activity for the years ended December 31, 2018, 2017, and 2016, was as follows:

Outstanding as of December 31, 2015

The intrinsic value of stock options exercised during the years ended December 31, 2017 and 2016, was $43
million and $26 million, respectively. Intrinsic value was measured using the fair market value at the date of exercise
for stock options exercised or at period end for outstanding stock options, less the applicable exercise price. The
Company issued new shares to satisfy exercised stock options.

Compensation Expense

The Company recorded $36 million, $34 million, and $36 million of expense related to stock awards for the years
ended December 31, 2018, 2017, and 2016, respectively. The Company recorded $8 million, $9 million (net of
impact of reduction in statutory federal corporate income tax rate), and $14 million as tax benefits related to stock
awards and stock options for the years ended December 31, 2018, 2017, and 2016, respectively.

The Company recognized tax benefits for the years ended December 31, 2018, 2017, and 2016, of $16 million, $28
million, and $39 million, respectively, from the issuance of stock in settlement of stock awards, and $17 million and
$10 million for the years ended December 31, 2017 and 2016, respectively, from the exercise of stock options. All
outstanding stock options were exercised as of December 31, 2017. Accordingly, there were no tax benefits
associated with the exercise of stock options in 2018.

Unrecognized Compensation Expense

As of December 31, 2018, the Company had less than $1 million of unrecognized compensation expense
associated with RSRs granted in 2018 and 2017, which will be recognized over a weighted average period of 1.3

As described in Note 14, the Company issued senior notes through the consolidating parent company, HII.
Performance of the Company's obligations under its senior notes outstanding as of December 31, 2018, including
any repurchase obligations resulting from a change of control, is fully and unconditionally guaranteed, jointly and
severally, on an unsecured basis, by each of HII's existing and future material domestic subsidiaries ("Subsidiary

subsidiary that did not provide a guarantee ("Non-Guarantors") is minor and HII, as the parent company issuer, did
not have independent assets or operations. There are no significant restrictions on the ability of the parent company
and the Subsidiary Guarantors to obtain funds from their respective subsidiaries by dividend or loan, except those
imposed by applicable law.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL
DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial
Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules
13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of
December 31, 2018. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer
concluded that, as of December 31, 2018, the Company's disclosure controls and procedures were effective to
ensure that information required to be disclosed in reports the Company files or submits under the Exchange Act is
(i) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii)
accumulated and communicated to management to allow their timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

During the three months ended December 31, 2018, no change occurred in the Company's internal control over
financial reporting that materially affected, or is reasonably likely to materially affect, the Company's internal control
over financial reporting.

The Company is in the process of implementing a new Enterprise Resource Planning ("ERP") system at its Ingalls
segment in the first quarter of 2019. The Company has followed a system implementation process that required
significant pre-implementation planning, design, and testing. The Company has also conducted and will continue to
conduct extensive post-implementation monitoring and process modifications to ensure that internal controls over
financial reporting are properly designed. The Company does not expect this system implementation to have a
material effect on its internal controls over financial reporting.

107

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, 2018, 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, 2018, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm,
as stated in their report, which is included in Item 8.

Segment Operating Income, Adjusted Segment Operating Income, Adjusted Segment Operating Margin,
Adjusted Net Earnings and Adjusted Diluted EPS are not measures recognized under GAAP. They should be
considered supplemental to and not a substitute for financial information prepared in accordance with GAAP.
We believe these measures are useful to investors because they exclude items that do not reflect our core
operating performance. They may not be comparable to similarly titled measures of other companies.

Forward-Looking Statements
Statements in this annual report, other than statements of historical fact, constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform
Act of 1995. Forward-looking statements involve risks and uncertainties that could cause our actual results to differ materially from those expressed in these statements. Factors
that may cause such differences include: changes in government and customer priorities and requirements (including government budgetary constraints, shifts in defense
spending, and changes in customer short-range and long-range plans); our ability to estimate our future contract costs and perform our contracts effectively; changes in procurement
processes and government regulations and our ability to comply with such requirements; our ability to deliver our products and services at an affordable life cycle cost and
compete within our markets; natural and environmental disasters and political instability; our ability to execute our strategic plan, including with respect to share repurchases,
dividends, capital expenditures and strategic acquisitions; adverse economic conditions in the United States and globally; changes in key estimates and assumptions regarding
our pension and retiree health care costs; security threats, including cyber security threats, and related disruptions; and other risk factors discussed in our filings with the U.S.
Securities and Exchange Commission. There may be other risks and uncertainties that we are unable to predict at this time or that we currently do not expect to have a material
adverse effect on our business, and we undertake no obligation to update any forward-looking statements. You should not place undue reliance on any forward-looking statements
that we may make. This annual report also contains non-GAAP financial measures and includes a GAAP reconciliation of these financial measures. Non-GAAP financial measures
should not be construed as being more important than comparable GAAP measures.
