Dear Shareholders,

As the security landscape evolves, Northrop Grumman is trusted to 
deliver the world’s most advanced security solutions. Leading-edge 
technologies, developed by our more than 100,000 employees, ensure 
our customers’ most urgent and challenging needs are met.

Partnering with the U.S. Air Force to successfully enter flight testing for 
the B-21 Raider, delivering on key milestones in support of national 
security space and the U.S. military's new Proliferated Warfighter Space 
Architecture and answering significant global demand for our weapons 
systems are just a few of the many incredible milestones achieved in 
2023.

Key program wins, a diverse portfolio aligned to our customers’ priorities 
and laser-focus on program performance strengthened our position as 
trusted global technology leaders.

Anchored by our business strategy, our balanced approach to capital deployment drives innovation and 
capacity to meet our customers’ needs and create value for shareholders. 

2023 Performance

Growing global demand for our solutions drove another year of strong performance. Our annual sales 
grew by 7% and totaled $39.3 billion. We achieved a book to bill ratio of 1.14 and ended the year with 
a record $84.2 billion in backlog. We generated $3.9 billion of operating cash flow and $2.1 billion of 
adjusted free cash flow* for the year. Despite a challenging macroeconomic environment, the underlying 
operating margins for the majority of our programs remained solid.

Defining the future of defense requires robust investment in our tools, people and innovation. In 2023, we 
invested $3.0 billion in research and development and capital expenditures into our business, providing 
a strong foundation for future growth. These investments included innovation areas such as the future of 
computing, microelectronics, the responsible use of artificial intelligence as well as the advanced 
networking required to tie our systems together.

Our disciplined approach to capital deployment returned $2.6 billion to shareholders through dividends 
and share repurchases.

Our Strong, Sustainable Culture

Innovation at this level requires diversity of thought and strong leadership. We were proud to receive 
DiversityInc’s “Top 50 Companies in Diversity” in recognition of our efforts to create a culture of 
belonging where people of every background can thrive.

Advancing sustainability through impactful conservation and sustainability projects remained a priority 
including efforts to protect land surrounding military installations.

Recognizing our commitment to our people, community, customers, shareholders and the environment, we 
were again named one of America’s Most Just Companies in 2023, and included on the Dow Jones 
Sustainability North America Index for the eighth consecutive year.

Positioning for the Future

With robust demand for our products and the trust of our customers, even greater milestones are on the 
horizon. Our team stands ready, remaining ahead of the expanding technological landscape. 

Our distinctive, integrated solutions remain in-line with our customer’s highest priorities. No matter what 
the future holds, the greater the challenge, the more determined we are to solve it.

Anchored by our values, we do the right thing, uphold our promises, commit to shared success and 
develop pioneering technologies, we expect to shape our world for generations to come.

I’m confident we have the right strategy, technology and team to lead our industry in 2024 and beyond.

HISTORY AND ORGANIZATION

PART I

History
Northrop Grumman Corporation (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”) 
is a leading global aerospace and defense technology company. We deliver a broad range of products, services and 
solutions to U.S. and international customers, and principally to the U.S. Department of Defense (DoD) and 
intelligence community. Our broad portfolio is aligned to support national security priorities and our solutions equip 
our customers with capabilities they need to connect, protect and advance humanity.

The company is a leading provider of space systems, military aircraft, missile defense, advanced weapons and long-
range fires capabilities, mission systems, networking and communications, strategic deterrence systems, and 
breakthrough technologies, such as advanced computing, microelectronics and cyber. We are focused on competing 
and winning programs that enable continued growth, performing on our commitments and affordably delivering 
capability our customers need. With the investments we've made in advanced technologies, combined with our 
talented workforce and digital transformation capabilities, Northrop Grumman is well positioned to meet our 
customers' needs today and in the future. For a discussion of risks associated with our operations, see “Risk 
Factors.”

The company originally was formed in 1939 in Hawthorne, California as Northrop Aircraft Incorporated and was 
reincorporated in Delaware in 1985, as Northrop Corporation. Northrop Corporation was a principal developer of 
flying wing technology, including the B-2 Spirit stealth aircraft. We developed into one of the largest defense 
technology companies in the world through a series of acquisitions, as well as organic growth, including the 
following: 

•

•

•

Organization
From time to time, we acquire or dispose of businesses and realign contracts, programs or businesses among and 
within our operating segments. Internal realignments are typically designed to leverage existing capabilities more 
fully and to enhance efficient development and delivery of products and services. At December 31, 2023, the 
company was aligned in four operating sectors, which also comprise our reportable segments: Aeronautics Systems, 
Defense Systems, Mission Systems and Space Systems.

CUSTOMER CONCENTRATION

Our largest customer is the U.S. government. Sales to the U.S. government accounted for 86 percent, 86 percent and 
85 percent of sales during the years ended December 31, 2023, 2022 and 2021, respectively. For further information 
on sales by customer type, contract type and geographic region, see Note 16 to the consolidated financial statements. 
See “Risk Factors” for further discussion regarding risks related to customer concentration.

COMPETITIVE CONDITIONS

We compete with many companies in the defense, intelligence and federal civil markets. The Boeing Company, 
General Dynamics, L3Harris Technologies, Lockheed Martin, and RTX are some of our primary competitors. Key 
characteristics of our industry include long operating cycles and intense competition, which is evident through the 
number of competitors bidding on program opportunities and the number of competitor protests of U.S. government 
procurement awards.

It is common in the defense industry for work on major programs to be shared among a number of companies. A 
company competing to be a prime contractor may, upon ultimate award of the contract to another competitor, serve 
as a subcontractor to the ultimate prime contracting company. It is not unusual to compete for a contract award with 
a peer company and, simultaneously, perform as a supplier to or a customer of that same competitor on other 
contracts, or vice versa.

SEASONALITY

No material portion of our business is considered to be seasonal.

the consolidated financial statements.

INTELLECTUAL PROPERTY

We routinely apply for and own a number of U.S. and foreign patents related to the technologies we develop. We 
also develop and protect intellectual property as trade secrets. In addition to owning a large portfolio of proprietary 
intellectual property, we license some intellectual property rights to third parties and we license or otherwise obtain 
access to intellectual property from third parties. The U.S. government typically holds licenses to patents developed 
in the performance of U.S. government contracts and may use or authorize others to use the inventions covered by 
these patents for certain purposes. See “Risk Factors” for further discussion regarding risks related to intellectual 
property.

RAW MATERIALS

We have experienced challenges with access to certain raw materials due to macroeconomic factors and several 
global events such as inflation, geopolitical conflicts and microelectronics shortages. In some cases, these challenges 
have significantly increased the cost and/or lead time required to obtain certain raw materials. Nonetheless, these 
challenges have not to date materially impacted our ability to perform on our contracts. See “Risk Factors” for 
further discussion regarding risks related to raw materials.

HUMAN CAPITAL

Fostering a culture that offers employees opportunities to live our values, deliver for our customers, and act 
responsibly and sustainably is central to our diverse and talented workforce. Our culture and values enable us to 
continue attracting qualified talent, particularly those with security clearances and requisite skills in multiple areas, 
including science, technology, engineering and math. This focus on our culture and workforce was a factor in our 
ability to hire approximately 14,500 new employees in 2023, and as of December 31, 2023, we have approximately 
101,000 employees. 

Additional information regarding our human capital strategy is available in our Environmental, Social, and 
Governance (ESG) Report, which can be found on our company website. Information on our website, including our 
ESG Report, is not incorporated by reference into this Annual Report.

Our Values and Culture
Our values reflect our priorities and form the bedrock of our culture: 

• We do the right thing – we earn trust, act with ethics, integrity and transparency, treat everyone with 

respect, value diversity and foster safe and inclusive environments.

• We do what we promise – we own the delivery of results, focused on quality.

• We commit to shared success – we work together to focus on the mission and take accountability for the 

sustainable success of our people, customers, shareholders, suppliers and communities. 

• We pioneer – with fierce curiosity, dedication and innovation, we seek to solve the world’s most 

challenging problems.

We believe our culture and values are vital to the ongoing success of the company, including our ability to attract 
and retain a talented and diverse workforce. Our values are also integral to our commitment to long-term 
sustainability, with robust ESG practices across our company. The company has a Standards of Business Conduct 
program. Our employees are empowered to raise concerns without fear of reprisal. In addition to full-time ethics 
professionals, we also have over 150 business conduct advisors who promote values and an ethical culture within the 
company.

Our annual Employee Experience Survey gives employees a voice and a mechanism to provide feedback on our 
culture and empower our leaders to enhance the employee experience. This anonymous survey encourages employee 
candor on key engagement and inclusion drivers, including belonging, respect, a sense of personal work 
accomplishment and recommending the company to others. In 2023, 81 percent of employees responded to the 
survey, an indication that our employees believe their feedback matters, and our survey results exceeded many of the 
global norms of our third party vendor for both engagement and inclusion. Our leaders review the survey responses 
and work collaboratively with their teams to take meaningful actions based on survey results.

Diversity, Equity and Inclusion
We value diversity and belonging in its broadest sense, as an enabling force that helps us pioneer, perform and 
deliver on quality, which results in value for our shareholders, customers, and employees. Across our U.S. employee 
population, as of December 31, 2023, 25 percent are female, 38 percent are people of color, 18 percent are veterans 
and 8 percent are persons with disabilities. At the vice president level, 35 percent are female and 20 percent are 
people of color. We strive to reach all parts of the diverse talent pools available now and in the future because we 
recognize that we benefit from having coworkers with different ideas, perspectives and approaches to help us 
innovate.

Talent Management 
Northrop Grumman’s talent strategy is focused on four key pillars: broadening talent pools; enhancing the employee 
experience; building leaders of the future; and enabling new ways of working. Our strategy addresses the external 
and internal landscape and ensures that we are able to attract, retain and develop the workforce necessary to support 
the continued success of the business.

We hold regular talent review discussions to ensure line of sight to talent at various levels of the organization. 
Succession plans are refreshed and reviewed to ensure a robust, diverse pipeline of talent and business continuity 
with a tight linkage to development. We focus on accelerating learning and development of our leaders by providing 
a combination of experiences, exposure and education.

Our employee development programs strengthen employee skills aligned to our current and future business needs 
through on-the-job development, knowledge sharing and tools to support career growth. Employees utilize curated, 
career-specific resources such as My Learning Experience, a machine learning enabled content aggregator that 
creates a personalized learning experience for each employee. Our Education Assistance Program subsidizes tuition 
and other educational institution fees to support development through job-related degrees and certificates. Our early-
in-career rotation program, Pathways, develops talent pipelines with both depth of critical skills and breadth of 
experiences. Our technical cohort programs cultivate technical, domain expertise and collaborative thought 
leadership for early through advanced career levels.

In a rapidly changing world, we maintain focus on keeping our team and our company prepared for the evolving 
future of work. In addition to offering our employees flexible work arrangements, caregiver support and mental 
health services that help our employees make their careers work within their lives, we also help our employees build 
the careers that will serve them into the future. We ensure that our employees have the tools and resources to 
develop their knowledge base and skill sets, so that they can continue to thrive at Northrop Grumman even in the 
midst of change. When our employees succeed and grow at work, our business succeeds and grows. Through a focus 
on our employees, we remain agile and innovative, adapting to the future as it unfolds before us. We provide many 
avenues for our employees to feel included, so we can hire, develop and retain the best people to support our 
common mission and better pioneer together.

Employee Health and Safety
Health and safety are a core focus in everything we do. People are our most valuable resource, and our goals have 
been, and continue to be, to keep our employees safe and position the company for long-term success.

Risk and hazard identification, abatement and prevention are key components of Northrop Grumman’s safety 
program. Everyone has a responsibility to identify workplace hazards and we empower employees to report these 
hazards without fear of repercussion. We evaluate the effectiveness of our health and safety programs externally, 
through benchmarking with industry peers and the U.S. Bureau of Labor Statistics. Internally, we determine 
program effectiveness by conducting trend analyses of our past performance.

Collective Agreements 
Approximately 4,100 employees are covered by 15 collective agreements in the U.S., of which we negotiated one 
renewal in 2023 and expect to negotiate five renewals in 2024.

See “Risk Factors” for further discussion regarding risks related to our workforce and employee relations.

REGULATORY MATTERS
Government Contract Security Restrictions
We are prohibited by the U.S. government from publicly discussing the details of certain classified programs. These 
programs are generally referred to as “restricted” in this Annual Report. The consolidated financial statements and 
financial information in this Annual Report reflect the operating results of our entire company, including restricted 
programs.

Contracts
We generate the majority of our business from long-term contracts with the U.S. government for development, 
production and support activities. Unless otherwise specified in a contract, allowable and allocable costs are billed to 
contracts with the U.S. government pursuant to the Federal Acquisition Regulation (FAR) and U.S. government 
Cost Accounting Standards (CAS), which are regulations that govern cost accounting requirements for government 
contracts. Examples of costs incurred by us and not billed to the U.S. government in accordance with applicable 
FAR and CAS requirements include, but are not limited to, unallowable employee compensation, charitable 
donations, interest expense, advertising, and certain legal and travel costs.

We monitor our contracts on a regular basis for compliance with our policies and procedures and applicable 
government laws and regulations. In addition, costs incurred and allocated to contracts with the U.S. government are 
routinely audited by the Defense Contract Audit Agency (DCAA).

Our long-term contracts typically fall into one of two contract types:

Cost-type contracts – Cost-type contracts include cost plus fixed fee, cost plus award fee and cost plus incentive fee 
contracts. Cost-type contracts generally provide for reimbursement of a contractor’s allowable costs incurred plus 
fee. As a result, cost-type contracts have less financial risk associated with unanticipated cost growth but generally 
provide lower profit margins than fixed-price contracts. Cost-type contracts typically require that the contractor use 
its best efforts to accomplish the scope of the work within some specified time and stated dollar limitation. Fees on 
cost-type contracts can be fixed in terms of dollar value or can be variable due to award and incentive fees, which 
are generally based on performance criteria such as cost, schedule, quality and/or technical performance. Award fees 
are determined and earned based on customer evaluation of the company’s performance against contractual criteria. 
Incentive fees are generally based on cost or schedule and provide for an initially negotiated fee to be adjusted later, 
based on the relationship of total allowable costs to total target costs or as schedule milestones are met. Award and 
incentive fees are included in total estimated sales to the extent it is probable that a significant reversal in the amount 
of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is 
subsequently resolved. We estimate variable consideration as the most likely amount to which we expect to be 
entitled.

Fixed-price contracts – Firm fixed-price contracts include a specified scope of work for a price that is a pre-
determined, negotiated amount and not typically subject to adjustment regardless of costs incurred by the contractor, 
absent changes by the customer. As a result, fixed-price contracts typically have more financial risk associated with 
unanticipated cost growth, but provide the opportunity for higher profit margins. Certain fixed-price incentive fee 
contracts provide for reimbursement of the contractor’s allowable costs plus a fee up to a cost ceiling amount, 
typically through a cost-sharing ratio that affects profitability. These contracts effectively become firm fixed-price 
contracts once the cost-share ceiling is reached. Time-and-materials contracts are considered fixed-price contracts as 
they specify a fixed hourly rate for each labor hour charged.

Profit margins on our contracts may vary materially depending on, among other things, the contract type, contract 
phase (e.g., development, low-rate production or mature production), negotiated fee arrangements, achievement of 
performance objectives, unexpected macroeconomic factors or other circumstances, and cost, schedule and technical 
performance.

See Note 1 to the consolidated financial statements and “Risk Factors” for further information regarding our 
contracts and Note 16 to the consolidated financial statements for sales by contract type.

Environmental
Our operations are subject to and affected by federal, state, local and foreign laws, regulations and enforcement 
actions relating to protection of the environment. We have incurred and expect to continue to incur capital and 
operating costs to comply with applicable environmental laws and regulations and to achieve our environmental 
sustainability commitments. See “Risk Factors” and Notes 1 and 12 to the consolidated financial statements for 
further information regarding environmental matters.

In 2022, we announced our next generation environmental sustainability goals, and in 2023, we announced our goals 
for water and waste. These goals focus on Northrop Grumman’s facilities in addition to supply chain partners and 
customers:

•

Item 1A. Risk Factors

Our consolidated financial position, results of operations and cash flows are subject to various risks, many of which 
are not exclusively within our control, that may cause actual performance to differ materially from historical or 
projected future performance. We encourage you to consider carefully the risk factors described below in evaluating 
the information contained in this report as the outcome of one or more of these risks could have a material adverse 
effect on our financial position, results of operations and/or cash flows.

Industry and Economic Risks

• We depend heavily on a single customer, the U.S. government, for a substantial portion of our business. Changes 

in this customer’s priorities and spending could have a material adverse effect on our financial position, results 
of operations and/or cash flows.

Our primary customer is the U.S. government, from which we derived 86 percent of our sales in 2023; we have a 
number of large programs with the U.S. Department of the Air Force, in particular. The U.S. government has the 
ability to delay, modify or cancel ongoing competitions, procurements and programs, as well as to change its future 
acquisition strategy. We cannot predict the impact on existing, follow-on, replacement or future programs from 
potential changes in the threat and global security environment, defense spending levels, government and budgetary 
priorities, political leadership, procurement practices and strategy, inflation and other macroeconomic trends, 
military strategy; or broader changes in social, economic, security or political demands and priorities. 

The U.S. government has the ability to terminate contracts, in whole or in part, for its convenience or for default 
based on performance. In the event of termination for convenience, contractors are generally protected by provisions 
covering reimbursement for costs incurred and profit on those costs up to the amount authorized under the contract, 
but not the anticipated profit that would have been earned. In the event of termination due to default, contractors 
may be required to pay for re-procurement costs in excess of the original contract price, net of the value of work 
accepted from the original contract, as well as other damages. Termination due to our default (or that of a teammate) 
could have a material adverse effect on our reputation, our ability to compete for other contracts and our financial 
position, results of operations and/or cash flows.

Where program cost estimates exceed certain thresholds, our customer has been, and may in the future be, required 
to provide congressional notification of significant or critical cost increases (or breaches) under the Nunn-McCurdy 
Act, which, in some circumstances, could result in program restructure or termination. For example, in January 2024 
the customer provided congressional notification that the Ground Based Strategic Deterrent (“Sentinel”) program is 
currently under a Nunn-McCurdy breach review.

The U.S. government also has the ability to stop work under a contract for a limited period of time for its 
convenience. The U.S. government has invoked and could invoke this ability across a limited or broad number of 
contracts. In the event of a stop work order, contractors are typically protected by provisions covering 
reimbursement for costs incurred to date and for costs associated with the temporary stoppage of work plus a 
reasonable fee. However, such temporary stoppages often introduce inefficiencies and result in financial and other 
damages for which contractors may not be able to negotiate full recovery. In some cases, they have also ultimately 
resulted and could result in termination of a contract for convenience or reduced future orders.

A significant shift in government priorities, programs or strategies could have a material adverse effect on our 
financial position, results of operations and/or cash flows.

•

Significant delays or reductions in appropriations for our programs and U.S. government funding more broadly, 
including a prolonged continuing resolution or breach of the debt ceiling, can negatively impact our business and 
programs and could have a material adverse effect on our financial position, results of operations and/or cash 
flows.

U.S. government programs are subject to annual congressional budget authorization and appropriation processes. 
For many programs, Congress appropriates funds annually even though the program performance period may extend 
over several years. Programs are often partially funded initially, with additional funds committed only as Congress 
makes further appropriations. When we or our subcontractors incur costs in excess of funds obligated on a contract, 
we are generally at risk for reimbursement unless and until additional funds are obligated to the contract. We cannot 

-9-

NORTHROP GRUMMAN CORPORATION

predict what funding will ultimately be approved for individual programs. In addition, pressures on, as well as laws 
and plans relating to the federal budget, potential changes in priorities and defense spending, the timing and 
substance of the appropriations process, use of continuing resolutions (with restrictions, e.g., on new starts) and the 
federal debt limit (including a breach of the federal debt ceiling), have adversely affected and could adversely affect 
the amount and timing of funding for individual programs and delay purchasing or payments by our customers. In 
the event government funding for our significant programs is reduced, delayed or unavailable, or orders are reduced, 
our contracts or subcontracts, or competitions for such programs have at times been, and in the future may be, 
terminated or changed. 

The U.S. continues to face an uncertain and changing political environment, along with substantial fiscal, economic 
and security challenges, which affect funding and budgetary priorities. The budget and macroeconomic 
environment, global security environment, political instability, and uncertainty surrounding the appropriations 
processes and the debt ceiling, remain significant short and long-term risks. See “Overview” in MD&A. In addition, 
high deficit levels and high debt servicing costs could drive cuts to federal spending. Considerable uncertainty exists 
regarding how future budget and program decisions will unfold. If annual appropriations bills are not timely enacted, 
the U.S. government may continue to operate under a continuing resolution (potentially of extended duration), 
restricting new contract or program starts, presenting resource allocation challenges and placing limitations on 
budgets. We also may face a prolonged government shutdown that could lead to program cancellations, disruptions 
and/or stop work orders and could limit the U.S. government’s ability to progress programs and make timely 
payments. A prolonged shutdown could limit our ability to perform on our contracts and successfully compete for 
new work. If the statutory debt limit is not increased adequately, we could be obligated to work without receiving 
timely payments, and a prolonged breach could have far-reaching adverse consequences. If current macroeconomic 
pressures (especially from inflation and labor and supply chain challenges) are prolonged or worsen, and increased 
costs continue, then existing or anticipated appropriated and contracted funds may not be sufficient to cover costs 
incurred on existing or future programs. 

Future funding for certain programs in which we participate may be reduced, delayed or cancelled. Budget cuts 
globally could adversely affect the viability of our subcontractors and suppliers. While we believe that our business 
is well-positioned in areas for future defense spending, changing priorities, budget pressures, defense spending cuts, 
challenges in the appropriations process, the possibility of a long-term continuing resolution (or series of continuing 
resolutions) and breach of the debt ceiling, ongoing fiscal debates and the global economic and security environment 
increase uncertainties and risk.

Significant delays or reductions in appropriations for our current and future programs; long-term funding under a 
continuing resolution; an extended debt ceiling breach or government shutdown; and/or future budget and program 
decisions, among other items, may negatively impact our business and programs and could have a material adverse 
effect on our financial position, results of operations and/or cash flows.

• We use estimates when accounting for contracts. Contract cost growth or changes in estimated contract revenues 

and costs can affect our profitability and our overall financial position.

Contract accounting requires judgment, including in assessing risks, estimating contract revenues and costs, and 
predicting future performance. Given the size and nature of our many contracts, estimating total revenues and costs 
at completion is complex and subject to many variables. When there is sufficient information to assess expected 
future performance, we consider performance related incentives, awards and penalties in estimating revenue and 
profit rates. Suppliers’ expected performance, and the availability and costs of labor, materials and components, are 
also considered.

Our operating income can be adversely affected when estimated contract costs increase, especially without 
comparable increases in revenue. There are many reasons estimated contract costs can increase, including inflation, 
labor challenges, supply chain challenges, and market and exchange rate volatility; delays or limitations in customer 
funding; design or other development challenges; production challenges (including from technical or quality issues 
and other performance concerns); inability to realize learning curves or other cost savings; changes in laws or 
regulations; actions necessary for long-term customer satisfaction; challenges caused by the global health 
environment; and natural disasters or environmental matters. 

We aim to mitigate this risk through contract terms, and we have submitted and may submit requests for equitable 
adjustment (REAs), engineering change proposals or other claims to seek recovery in whole or in part for our 
increased costs. We have also sought, and will seek, other avenues, as appropriate, to compensate the company for 
certain unexpected cost increases. However, our contracts may not enable full recovery, and/or the government may 
disagree with our requests and may not have funding to cover them. 

-10-

NORTHROP GRUMMAN CORPORATION

Our risk varies with the type of contract. Fixed-price contracts inherently tend to have more financial risk than cost-
type contracts, including as a result of inflationary pressures, labor rates and shortages, and supplier challenges. In 
2023, approximately half of our sales were derived from fixed-price contracts. We have more often entered into 
fixed-price contracts where costs can be more reasonably estimated based on actual experience, such as for mature 
production programs. However, our customers have sought, and may in the future seek, fixed-price contracts for 
development programs, combined development and production programs, or low-rate initial production programs, 
where the risks are greater. In addition, our contracts contain provisions relating to cost controls and audit rights. If 
we do not achieve our estimates or meet terms in our contracts, our profitability has at times been and may be 
reduced, and we have incurred and may incur losses. 

Certain of our fixed-price contracts include or may include fixed-price development work. This work is inherently 
more uncertain, and, as a result, there is typically more variability in estimates of the costs to complete the 
development stage. As work progresses into production, the risks associated with estimating total costs are typically 
reduced. While management uses its best judgment to estimate costs associated with fixed-price contracts, future 
events could result in significant adjustments.

Under cost-type contracts, allowable costs are generally subject to reimbursement plus a fee. We often enter into 
cost-type contracts for development programs with complex design and technical challenges. These cost-type 
programs may have award or incentive fees that are uncertain and may be earned over extended periods or towards 
the end of the contract. In these cases, the financial risks are typically in recognizing profit, which ultimately may 
not be earned, or program cancellation if cost, schedule, or technical performance issues arise. We also face 
additional financial risk when solicitations require us to bid on cost-type development work and fixed-price 
production lots and/or options in one submission, or cost-type development work requiring us to provide certain 
items at our expense or with little or no fee. Ongoing macroeconomic challenges increase these risks. 

Because of the significance of management’s judgments and the estimation processes, and the difficulties inherent in 
estimating future costs, particularly in a challenging macroeconomic environment, it is possible that we could see 
materially different results. Changes in underlying assumptions, circumstances or estimates, and the failure to 
recover on requests for equitable adjustments, engineering change proposals or other claims could have a material 
adverse effect on the profitability of one or more of our contracts and on our overall financial position, results of 
operations and/or cash flows. See “Critical Accounting Policies and Estimates” in MD&A and Note 12 to the 
consolidated financial statements.

•

The global macroeconomic environment could negatively impact our business and our financial position, results 
of operations and/or cash flows could be materially adversely affected.

Our business, financial position, results of operations and/or cash flows have been and may continue to be adversely 
impacted by the global macroeconomic environment, which has experienced extraordinary challenges, including 
high rates of inflation; increased interest rates; widespread disruptions in supply chains; workforce challenges, 
including labor shortages; and market volatility, including exchange rate volatility. These challenges have, among 
other things, led to increased costs, labor and supply shortages, and delays and disruption in performance, as well as 
competing demands for scarce resources. Those challenges have adversely impacted our customers, our industry, 
our company, our suppliers and others with whom we do business. While some aspects of the macroeconomic 
environment have improved, and we have been able to mitigate some of the challenges (especially with respect to 
labor shortages), other challenges persist. We cannot predict the future trajectory or duration of this risk, including 
how the macroeconomic environment will evolve or how it will continue to impact us. 

We continue to work proactively to mitigate the challenges caused by the macroeconomic environment, including, 
in some cases, seeking the inclusion of economic price adjustment clauses or seeking to recover on requests for 
equitable adjustments, engineering change proposals or other claims. However, if we are unable to do so 
successfully, our financial position, results of operations and/or cash flows could be materially adversely affected. 

•

Competition within our markets and bid protests may affect our ability to win new contracts and result in reduced 
revenues and market share.

We operate in highly competitive markets and our competitors may have more financial capacity or more extensive 
or specialized engineering, manufacturing, marketing or servicing capabilities. They may be willing to accept more 
risk or lower profitability in competing for contracts. We have seen, and anticipate we will continue to see, increased 
competition in some of our core markets, especially as a result of our customers’ budget pressures, their focus on 
affordability and competition, and our own success in winning business. We are facing increasing competition in the 
U.S. and outside the U.S. from U.S., foreign and multinational firms, including new entrants, and anticipate that 
acquisitions within our industry could further increase competition. We are also facing increasing competition for, 

-11-

NORTHROP GRUMMAN CORPORATION

and more limited access to various critical products, services and other supplies. In some instances, foreign 
companies may receive loans, subsidies and other assistance from their governments that may not be available to 
U.S. companies and foreign companies may be subject to fewer restrictions on technology transfer. Some customers, 
including the DoD, are turning to commercial contractors, rather than traditional defense contractors, for some 
products and services, and continue to utilize small business contractors or determine to source work internally. Our 
success in competing depends, in part, on our ability to remain cost-competitive, accurately anticipate our 
customers’ needs and successfully to effect our digital transformation strategy and adopt and integrate new digital 
manufacturing and operating technologies into our products and services.

Bid protests can result in contract modifications or the award decision being reversed and loss of the contract award. 
Even where a bid protest does not result in such a loss, it can delay the start of contract activities and earnings. 

If we are unable to continue to compete successfully against our current or future competitors, or prevail in protests, 
or to prevail against other attempts to interfere with our ability to obtain and retain awards, we may experience 
declines in future revenues and market share, which could have a material adverse effect on our financial position, 
results of operations and/or cash flows.

Legal and Regulatory Risks

• We are subject to various investigations, claims, disputes, enforcement actions, litigation, and other legal 

proceedings that could ultimately be resolved against us.

The size, nature and complexity of our business make us particularly susceptible to investigations, claims, disputes, 
enforcement actions, prosecutions, litigation and other legal proceedings (collectively “legal proceedings”), 
particularly those involving governments, which have at times been, and may continue to be, increasingly 
aggressive. We are and may become subject to legal proceedings globally (including criminal, civil and 
administrative) and across a broad array of matters, including, but not limited to, government contracts, cost 
accounting, financial accounting and reporting, false statements or claims, cybersecurity and pension accounting and 
other employee benefit plan matters. These matters can divert resources; result in administrative, civil or criminal 
fines, penalties or other sanctions (including judgments, convictions, consent or other voluntary decrees or 
agreements), compensatory, treble or other damages, non-monetary relief, or other liabilities; and otherwise harm 
our business and our ability to obtain and retain awards. Certain allegations may lead to suspension or debarment 
from government contracts or suspension of export/import privileges for the company or one or more of its 
components. Suspension or debarment or criminal resolutions in particular could have a material adverse effect on 
the company because of our reliance on government contracts and export authorizations. An investigation, claim, 
dispute, enforcement action or litigation, even if pending or not ultimately substantiated or if fully indemnified or 
insured, can negatively impact our reputation among our customers and the public, and make it substantially more 
difficult for us to compete effectively for business, obtain and retain awards, ensure adequate funding for our 
programs or obtain adequate insurance in the future. Investigations, claims, disputes, enforcement actions, litigation 
or other legal proceedings could have a material adverse effect on our financial position, results of operations and/or 
cash flows. See Note 11 to the consolidated financial statements for information regarding investigations, claims and 
litigation. 

•

The improper conduct of employees, agents, subcontractors, suppliers, business partners or joint ventures in 
which we participate can impact our reputation, our ability to do business and our financial position, results of 
operations and/or cash flows.

We have implemented policies, training and other compliance controls, and have negotiated contractual terms 
designed to prevent misconduct by employees, agents or others working with us or on our behalf that would violate 
the applicable laws of the jurisdictions in which we operate, including laws governing improper payments to 
government officials, the protection of export controlled or classified information, false claims, procurement 
integrity, cost accounting and billing, competition, information security and data privacy, intellectual property and 
contract terms. However, we cannot ensure that we will prevent all such misconduct committed by our employees, 
agents, suppliers, partners or others working with us or on our behalf. We have in the past experienced and may in 
the future experience such misconduct, despite a vigorous compliance program, our values and strong culture. This 
risk of improper conduct may increase as we continue to expand globally, with greater opportunities and demands to 
do more business with local and new partners, and in new environments. At the same time, law enforcement 
agencies are continuing to focus collaboratively on combating global corruption and other misconduct. In the 
ordinary course we form and are members of joint ventures or other business arrangements and/or invest in third 
parties with whom we do business. Notwithstanding our robust processes, we may be unable to prevent misconduct 
or violations of applicable laws by these joint ventures (including their officers, directors and employees) or our

partners. Improper actions by our employees or those with whom or through whom we do business subjects us to 
risk of administrative, civil or criminal investigations and enforcement actions; monetary and non-monetary 
penalties; liabilities; and the loss of privileges and other sanctions, including suspension and debarment, which could 
negatively impact our reputation and ability to conduct business and could have a material adverse effect on our 
financial position, results of operations and/or cash flows.

•

As a U.S. government contractor, we and our partners are subject to various procurement and other laws, 
regulations and contract terms applicable to our industry, as well as those more broadly applicable to industry, 
and we could be adversely affected by changes in such laws, regulations or terms, or any negative findings by the 
U.S. government as to our compliance with them. We also may be adversely affected by changes in our 
customers’ business practices globally.

U.S. government contractors (including their subcontractors and others with whom they do business) must comply 
with various specific procurement laws, regulations, rules and other legal requirements, as well as ones more 
broadly applicable. These various legal requirements, although sometimes customary in government contracting, 
increase costs and risks. They have been and are evolving at a significant pace. The costs are not always fully 
recoverable. New laws or other requirements, or changes to existing ones (including, for example, related to cyber, 
information protection, cost accounting, environment, sustainability, securities, competition, compensation costs, 
taxes, counterfeit parts, pensions, and use of certain non-US equipment) or more expansive interpretations or other 
changes in how government agencies construe existing ones, can significantly increase our costs and risks and 
reduce our profitability.

We operate in a highly regulated environment and are routinely audited and reviewed by the U.S. government and 
its agencies, such as the DCAA, Defense Contract Management Agency (DCMA) and the DoD Inspector General. 
These agencies review performance under our contracts, our cost structure and accounting, and our compliance, and 
the adequacy of our systems in meeting government requirements. Costs ultimately found to be unallowable or 
improperly allocated may not be reimbursed or may be refunded. When an audit uncovers improper or illegal 
activities, we are subject to possible civil and criminal penalties, sanctions, or suspension or debarment. Whether or 
not illegal activities are alleged, the U.S. government has the ability to decrease or withhold certain payments when 
it deems systems to be inadequate, with significant financial impact, regardless of the ultimate outcome. In addition, 
we risk serious reputational harm in situations involving allegations of impropriety made against us or our business 
partners.

Our industry has experienced, and we expect it will continue to experience, significant changes to business practices 
globally, in part as a result of changes in the global security and threat environment and an increased focus on 
affordability, efficiencies, business systems, recovery of costs and a reprioritization of available defense funds. We 
have experienced and may continue to experience an increased number of audits and challenges to our claims and 
our business systems for current and past years, as well as longer periods to close audits, broader requests for 
information and an increased risk of withholdings of payments. The U.S. government has been pursuing and may 
continue to pursue policies that could negatively impact our profitability, including those that shift additional 
responsibility and performance risks to the contractor. Changes in procurement practices, including those favoring 
incentive-based fee arrangements; fixed price development or long-term production programs; different award 
criteria; non-traditional contract provisions; and contract negotiation offers that indicate what our costs should be, 
have affected and may in the future affect our profitability and predictability.

We (including our subcontractors and others with whom we do business) also are subject to, and expected to 
perform in compliance with, a vast array of federal, state and local laws, regulations, contract terms and 
requirements related to our industry, our products and the businesses we operate, as well as those more broadly 
applicable to industry, such as securities laws and regulations. These requirements, whether specific to our industry 
or broadly applicable, may limit our ability to achieve our goals. If we are found to have violated any such 
requirements, or are found not to have acted responsibly, we may be subject to a wide array of actions, including 
contract modifications or termination; payment withholds; the loss of export/import privileges; administrative, civil 
or criminal judgments or penalties (including convictions, agreements, fines, damages and non-monetary relief); or 
suspension or debarment. 

If we or those with whom we do business do not comply with the laws, regulations, rules, contract terms and 
processes to which we are subject or if customer business practices or requirements change significantly, including 
with respect to allowable costs, it could affect our ability to compete and have a material adverse effect on our 
financial position, results of operations and/or cash flows.

Environmental matters, including climate change, unforeseen costs associated with compliance and remediation 
efforts, and government and third party claims, could have a material adverse effect on our reputation and our 
financial position, results of operations and/or cash flows.

Our operations are subject to and affected by a variety of federal, state, local and foreign environmental laws and 
regulations, including as they may be expanded, otherwise changed or enforced differently over time. Compliance 
with these existing and evolving environmental laws and regulations requires, and is expected to continue to require, 
significant operating and capital costs. For example, some of these recently enacted laws and regulations prohibit the 
use of certain chemicals or other substances that are used in our business, which may require us to identify alternate 
sources, result in additional costs and/or otherwise impact our business and operations. New and evolving laws, 
regulations and rule makings globally are expected to impose different and more restrictive standards and require 
greater disclosures. They could also require capital investments, could adversely impact our ongoing operations, and 
could require changes on a more accelerated time frame. Our suppliers are expected to face similar challenges and 
incur additional compliance costs that may be passed on to us. These direct and indirect costs may adversely impact 
our results of operations and financial condition, and, if we are unable to comply with legislative and regulatory 
requirements or meet our sustainability objectives, our reputation and ability to do business could be negatively 
impacted. In addition, our customers’ requirements, priorities and ways of doing business with respect to 
environmental matters, and climate change specifically, also may have an impact on our business, operations and 
financial success. For example, in 2022, the SEC and FAR council issued proposed rule-makings on climate change. 
The proposed rules, depending on how they are finally adopted, as well as other changes the government might 
implement, could impose significant new burdens on the company and our suppliers, with significant potential costs 
and operational impacts, and adversely impact our ability to win business and operate successfully.

Environmental matters may significantly impact our business and operations and present evolving risks and 
challenges. Environmental impacts, including climate change specifically, create short and long-term financial risks 
to our business globally. We have significant operations located in regions that have been, and may in the future be, 
exposed to significant weather events and other natural disasters. Increased worldwide focus on climate change has 
led to legislative and regulatory efforts to combat both potential causes and adverse impacts of climate change, 
including regulation of greenhouse gas emissions. New or more stringent laws and regulations related to greenhouse 
gas emissions and other climate change related concerns have affected and will likely continue to affect us, our 
suppliers and our customers. The company has set a goal to achieve net zero greenhouse gas emissions in our 
operations by 2035 and is committed to working to achieve its climate change and other sustainability goals. We are 
working to identify opportunities to utilize alternatives to fossil-based energy sources, to decrease our greenhouse 
gas emissions, to reduce our consumption of water and generation of waste, and to ensure our compliance with 
environmental regulations where we operate, enhancing our record of environmental sustainability. However, the 
costs of doing so may be greater than expected, and there can be no assurance the company will achieve its 
objectives, or meet the evolving sustainability expectations and standards of our investors and other external 
stakeholders.

We may be subject to substantial administrative, civil or criminal fines, penalties or other sanctions (including 
suspension and debarment) for violations of environmental laws. If we are found to be in violation of the Federal 
Clean Air Act or the Clean Water Act, the facility or facilities involved in the violation could be placed by the 
Environmental Protection Agency on a list of facilities that generally cannot be used in performing on U.S. 
government contracts until the violation is corrected.

We incur, and expect to continue to incur, substantial remediation costs related to the cleanup of pollutants 
previously released into the environment. Stricter or different remediation standards or enforcement of existing laws 
and regulations; new requirements, including regulation of new substances; discovery of previously unknown or 
more extensive contamination or new contaminants; imposition of fines, penalties, or damages (including natural 
resource damages); a determination that certain remediation or other costs are unallowable; rulings on allocation or 
insurance coverage; and/or the insolvency, inability or unwillingness of other parties to pay their share, could require 
us to incur material additional costs in excess of those anticipated. 

We are and may become a party to various legal proceedings and disputes involving government and private parties 
(including individual and class actions) relating to alleged impacts from pollutants released into the environment, 
including bodily injury and property damage. These matters could result in material compensatory or other damages, 
remediation costs, penalties, and non-monetary relief, and adverse determinations on allowability or insurance 
coverage.

-14-

 
NORTHROP GRUMMAN CORPORATION

Government and private parties also seek to hold us responsible for liabilities or obligations related to former 
operations that have been divested or spun-off and/or for which we believe other parties have agreed to be 
responsible and/or to indemnify us. These rights may not be sufficient to protect us.

The impact of these factors is difficult to predict, but one or more of them could harm our reputation and business 
and have a material adverse effect on our financial position, results of operations and/or cash flows.

•

Unanticipated changes in our tax provisions or exposure to additional tax liabilities could affect our profitability 
and cash flow.

We are subject to income and other taxes in the U.S. and foreign jurisdictions. Changes in applicable tax laws and 
regulations, or their interpretation and application, including the possibility of retroactive effect, have affected and 
could affect our tax expense. In addition, the final determination of any tax audits or related litigation, in particular 
with regard to our positions on research credits and timing of revenue recognition under IRC Section 451(b), could 
be materially different from our historical income tax provisions and accruals. 

We may be subject to future tax audits and legal challenges involving OATK, which we acquired in 2018, or the 
spinoff of its then subsidiary Vista Outdoor, and we may be unable to obtain indemnification or we may be required 
to indemnify Vista. 

Changes in our tax provisions or an increase in our tax liabilities, whether due to changes in applicable laws and 
regulations, the interpretation or application thereof, or a final determination of tax audits or litigation or agreements, 
could have a material adverse effect on our financial position, results of operations and/or cash flows.

Business and Operational Risks

•

Our business could be negatively impacted by cyber and other security threats or disruptions.

As a defense contractor, we face significant cyber and other security threats. They include, among other things, 
attempts to gain unauthorized access to sensitive information or otherwise compromise the integrity, confidentiality 
and/or availability of our systems, hardware and networks, and the information on them; insider threats; 
ransomware; threats to the safety of our directors, officers and employees; threats to our facilities, infrastructure, 
products (we produce and use), and subcontractors or other suppliers (referred to inclusively as suppliers); and 
threats from terrorist acts, espionage, civil unrest and other acts of aggression. We are also subject to increasing 
government, customer and other cyber and security requirements, including disclosure obligations.

We have robust measures in place to address and mitigate cyber-related risks. However, we have experienced cyber 
attacks and expect we will continue to experience additional attacks in the future, including from nation states and 
non-state actors. We continue to invest in the cybersecurity and resiliency of our networks and products and to 
enhance our internal controls and processes, which are designed to help protect our systems and infrastructure, and 
the information they contain. These include timely detection of incidents through monitoring, training, incident 
response capabilities, and mitigating cyber and security risks to our data, systems, products and services. We also 
partner with the government and others in our industry to help protect national security. However, given the 
complex, continuing and evolving nature of cyber and other security threats, including threats from targeting by 
more advanced and persistent adversaries, including nation states and other actors, these efforts may not be fully 
effective, particularly against previously unknown vulnerabilities that could go undetected for an extended period.

Our customers and partners (including our suppliers and joint ventures) to whom we entrust confidential data, and 
on whom we rely to provide products and services, face similar threats and growing requirements, including ones for 
which others may seek to hold us responsible. We depend on our customers, suppliers, and other business partners to 
implement and verify adequate controls and safeguards to protect against and report cyber incidents. If they fail to 
deter, detect or report cyber incidents in a timely manner, we may suffer financial and other harm, including to our 
information, operations, performance, employees and reputation. 

Although we implement various measures and controls to monitor and mitigate risks associated with these threats 
and to increase the cyber resiliency of our infrastructure and products, there can be no assurance that these processes 
will be sufficient. Successful attacks could lead to losses or misuse of sensitive information or capabilities; theft or 
corruption of data; harm to personnel, infrastructure or products; financial costs and liabilities; protracted disruptions 
in our operations and performance; and the misuse of our products, as well as damage to our reputation as a provider 
of cyber-related or cyber-protected goods and services. We have not always been able to and may in the future not 
always be able to obtain adequate insurance to cover our losses.

Cyber threats, both on premises and in the cloud, are evolving and include, but are not limited to: malicious 
software, destructive malware, ransomware, attempts to gain unauthorized access to systems or data, disruption to 

-15-

NORTHROP GRUMMAN CORPORATION

operations, critical systems or denial of service attacks; unauthorized release of confidential, personal or other 
protected information (ours or that of our employees, customers or partners); corruption of data, networks or 
systems; harm to individuals; and loss of assets. We have been and could be impacted by cyber threats or other 
disruptions or vulnerabilities found in products or services we use or in our internal, partners’ or customers’ systems 
that are used in connection with our business. Some of these threats are zero-day attacks associated with previously 
unknown vulnerabilities in third party software or products we utilize in our business. Cyber events, if not prevented 
or effectively mitigated, have caused and could cause harm and require remedial actions. They could also damage 
our reputation, disrupt performance, impact our ability to obtain future insurance coverage, and lead to loss of 
business, regulatory actions, liabilities or other financial losses, for which we do not have adequate sources of 
recovery.

We provide systems, products and services to various customers who also face cyber threats. Our systems, products 
and services may not be able to detect or deter threats, or effectively to mitigate resulting losses. These losses could 
adversely affect our customers and our company.

We also face increasing and evolving disclosure obligations related to cyber and other security events. Despite 
rigorous processes, we risk failing to meet all our existing or future disclosure obligations and/or having our 
disclosures misinterpreted. National security or public safety considerations may also affect, or in limited instances 
prevent, our public disclosure of a cybersecurity incident in certain circumstances.

We also face threats to our physical security, including to our facilities and the safety and well-being of our people. 
These threats could involve terrorism, insider threats, workplace violence, civil unrest, natural disasters, damaging 
weather, or fires, which could adversely affect our company. Our customers and suppliers face similar risks that, if 
realized, could also adversely impact our operations. Such acts could cause delays, manufacturing downtime, or 
other impacts that could detrimentally impact our ability to perform our operations. We could also incur 
unanticipated costs to remediate impacts and lost business. 

The occurrence and impact of these various risks are difficult to predict, but one or more of them could have a 
material adverse effect on our financial position, results of operations and/or cash flows.

•

Our ability to win new competitions and meet the needs of our customers depends, in part, on our ability to 
maintain a qualified workforce.

Our operating results and growth opportunities are heavily dependent upon our ability to attract and retain sufficient 
qualified and diverse personnel who are or can reasonably be cleared (and obtain program access), who have the 
requisite skills in multiple areas, including science, technology, engineering and math, and who share our values and 
are able to operate effectively consistent with our culture. Outside the U.S., it is increasingly important that we are 
also able to attract and retain personnel with relevant local qualifications and experience. We continue to face 
increased competition for talent, both with traditional defense companies and commercial companies, globally, and 
with increasing wage rates. Although we have realized benefits from extensive hiring and retention programs in 
recent years, the risk of insufficient personnel may increase, either broadly or with respect to select critical staffing 
requirements.	If necessary qualified personnel are more scarce or more difficult to attract or retain under reasonable 
terms, or if we experience a high level of attrition, generally or in particular areas, or if such personnel are 
increasingly unable to obtain security clearances or program access on a timely basis or are unable to be timely and 
effectively trained, we would expect higher labor-related costs and we could face challenges performing on various 
of our programs and meeting financial expectations. In addition, the macroeconomic environment, including 
continued challenges in the global labor market, may further affect our ability to hire, develop and retain the 
necessary talented and diverse workforce, and to maintain performance levels and our corporate culture. There is 
also the risk that we are unable to achieve our environmental, social and governance (ESG) goals which may be 
required by certain of our shareholders, employees, the government and other stakeholders, which could adversely 
impact our reputation, business and ability to hire and retain talent.

Certain of our employees are covered by collective agreements. We generally have been able to renegotiate renewals 
to expiring agreements without significant disruption of operating activities. However, the environment appears to 
be shifting, and if, for example, we experience difficulties with renewals and renegotiations of existing collective 
agreements, or if our employees pursue new collective representation, we could incur additional expenses and 
impacts on operating efficiency and may be subject to work stoppages or other labor-related disruptions. Any such 
expenses or delays could adversely affect our performance and results.

-16-

NORTHROP GRUMMAN CORPORATION

If we are unable to attract and retain a qualified workforce, we may be unable to maintain our competitive position 
or achieve our results, and it could have a material adverse effect on our financial position, results of operations and/
or cash flows.

•

Our earnings and profitability depend, in part, on subcontractor and supplier performance and financial viability 
as well as raw material and component availability and pricing.

We rely on other companies to provide raw materials, chemicals, parts and components and subsystems for our 
products, produce hardware elements and sub-assemblies, provide software and intellectual property, provide 
information about the parts they supply to us, and perform some of the services we need for our operations or 
provide to our customers, and to do so in compliance with all applicable laws, regulations and contract terms, while 
maintaining strong values and cultures. Disruptions or performance problems with our subcontractors or other 
suppliers (referred to inclusively as suppliers), unanticipated cost growth for the products and services they provide, 
failure to meet regulatory or contractual requirements, unethical behavior, or a misalignment between our 
contractual obligations to our customers and our agreement with our suppliers, have had and may continue to have 
various adverse impacts on the company, including on our ability to meet our commitments to customers and 
financial expectations. This risk of delays and disruptions in the supply chain, and supply chain challenges more 
broadly, has been and continues to be heightened globally, in the current macroeconomic environment.

Our ability to perform our obligations on time is adversely affected if one or more of our suppliers is unable to 
provide the agreed-upon products, materials or information, or perform the agreed-upon services in a timely, 
compliant and cost-effective manner. We also may experience challenges performing if we are unable to use certain 
raw materials, chemicals or other substances due to laws or other regulations that restrict or prohibit the use of such 
items and cannot obtain a reasonable substitute on a cost-effective basis. Changes in political or economic 
conditions, including changes in demand, changes in the macroeconomic environment (including inflation and labor 
and supply chain challenges), changes in defense budgets and/or priorities, changes in the global security 
environment, changes in export/import restrictions, evolving requirements, or changes in access to critical 
technology and materials (including metals and components), among others, have adversely affected and could in 
the future adversely affect the financial stability of our suppliers and/or their ability to perform effectively. The 
inability of our suppliers to perform effectively has required and may require us to provide them additional support 
and/or to transition to alternate suppliers, if available, with additional costs and delays. We expect we will need to 
continue to provide additional resources to support certain of our suppliers in performing under our contracts. In 
addition, if we are unable to do that, we may face additional losses and liabilities under our current contracts and 
adversely impact the prospects for certain new ones.

In connection with our U.S. government contracts, we are required to procure certain materials, components and 
parts from supply sources approved by the customer and/or are restricted from procuring products or services from 
certain sources. For example, we require assured access to certain microelectronics. Our ability to produce and/or 
deliver products will be significantly impacted if the microelectronics manufacturing supply chain is cut off or 
significantly delayed. For some components, there has been or may be only one supplier, or one domestic supplier. 
If that supplier cannot meet our needs or if we are unable to procure components from certain suppliers due to 
regulatory restrictions, we may be unable to find a suitable alternative and to meet our obligations.

We and our suppliers are also facing increased regulatory requirements globally. We may be held responsible not 
only for our compliance, but that of our suppliers. Our procurement practices are intended to reduce the risk we 
procure counterfeit, unauthorized or otherwise non-compliant parts or materials. We rely on our suppliers also to 
comply with applicable laws and contract terms, to ensure the quality of their components and effectively to mitigate 
the risk of cyber and security threats or other disruptions to their performance. 

If our suppliers are not financially viable, incur increased costs of delays, fail to comply with legal requirements, or 
otherwise fail to address these risks or meet their obligations to us, it could have a material adverse effect on our 
financial position, results of operations and/or cash flows.

•

Our international business exposes us to additional risks, including risks related to geopolitical and economic 
factors, laws and regulations.

Sales to customers outside the U.S. are an important component of our strategy. Our international business 
(including our participation in joint ventures, requirements for local content, and our global supply chain) is subject 
to numerous political and economic factors, legal requirements, cross-cultural considerations and other risks 
associated with doing business globally. These risks differ in some respects from those associated with our U.S. 

-17-

NORTHROP GRUMMAN CORPORATION

business and our exposure to such risks is expected to increase if and as our international business continues to 
grow.

Our international business is generally subject to both U.S. and foreign laws, regulations and practices. Failure by 
us, our employees, partners or others with whom we work to comply with applicable laws and regulations could 
result in administrative, civil, commercial or criminal liabilities, including suspension or debarment from 
government contracts or suspension of export/import privileges. Failure to comply with local practices can adversely 
impact our ability to win and perform business. New regulations and requirements, or changes to existing ones in 
countries in which we operate can significantly increase our costs and risks of doing business internationally. Our 
customers outside of the U.S. also often have the ability to terminate contracts for convenience as well as for default 
based on performance. Suspension or debarment, or termination of a contract due to default could have a material 
adverse effect on our reputation, our ability to compete for other contracts and our financial position, results of 
operations and/or cash flows. Despite robust processes, we also face risks related to the unintended or unauthorized 
use of our products and resources.

Changes in laws, political leadership and environment, and/or security risks may dramatically affect our ability to 
conduct or continue to conduct profitable business in international markets. Our international business is impacted 
by changes in U.S. and non-U.S. national policies and priorities, and geopolitical relationships, any of which may be 
influenced by changes in the global threat environment, political leadership, geopolitical and economic uncertainties, 
world events, government budgets, inflationary pressures, sanctions imposed in countries where we do business or 
seek to do business, and economic and political factors more generally. The U.S. and its allies continue to face a 
global security environment of heightened tensions and instability, threats from state and non-state actors, including 
major global powers, as well as terrorist organizations, emerging nuclear tensions, and diverse regional security 
concerns. Any of these factors may impact demand for our products and services, funding for programs, our ability 
to perform, our supply chain, export authorizations, purchasing decisions or customer payments. Global 
macroeconomic conditions, as well as fluctuations in foreign currency exchange rates and credit, are also likely to 
further impact our business.

Our contracts with non-U.S. customers in some cases include terms and reflect legal requirements that create 
additional risks. They may include requirements to hire, invest, manufacture or purchase locally, or specific 
financial obligations, including offset obligations, and they may provide for significant penalties if we fail to meet 
such requirements. They may also require us to enter into letters of credit, performance bonds, bank guarantees or 
other financial arrangements. If we are dependent on certain suppliers, as in the U.S., we face risks related to their 
failure to perform in accordance with legal requirements, particularly where we rely on a sole source supplier. Our 
ability to sell products globally could be adversely affected if we are unable to design our products on a cost 
effective basis or to obtain and retain all necessary export authorizations, which the U.S. government can deny, 
change or revoke for reasons outside our control. Our business outside of the U.S. also depends on our ability to 
attract and retain sufficient qualified personnel with the skills and/or security clearances in the markets in which we 
do business. We may need to partner successfully with non-U.S. companies, including through joint ventures, 
teaming agreements, co-production or other arrangements. This risk includes the ability to identify and negotiate 
appropriate arrangements with qualified and acceptable local partners, potential exposure for their actions, and the 
ability effectively to terminate these arrangements. This risk is complicated further when we partner with 
government-affiliated entities.

The products and services we provide, including those provided by suppliers and joint ventures, are sometimes in 
countries with unstable governments, economic or fiscal challenges, military or political conflicts, different business 
practices and/or developing legal systems. This may increase the risk to our employees, suppliers or other third 
parties, including for their safety, and increase our risk to a wide range of financial consequences and other 
liabilities, as well as loss of property or damage to our products.

The occurrence and impact of these factors is difficult to predict, but one or more of them could have a material 
adverse effect on our financial position, results of operations and/or cash flows.

• We face various risks related to health epidemics, pandemics and similar outbreaks, which may have material 

adverse effects on our business, financial position, results of operations and/or cash flows.

We face a wide variety of risks related to health epidemics, pandemics and similar outbreaks, especially of infectious 
diseases. The global health environment has contributed to business slowdowns or shutdowns, labor shortages, 
supply chain challenges, changes in government spending and requirements, regulatory challenges, inflationary 
pressures and market volatility. Although we aim to mitigate impacts of adverse changes in the global health 
environment, these changes can be unpredictable and we may be unable to effectively mitigate them. If a health 

-18-

NORTHROP GRUMMAN CORPORATION

epidemic, pandemic or similar outbreak were to occur or worsen, we likely would experience broad and varied 
impacts, including potentially to our workforce and supply chain, with inflationary pressures and increased costs 
(which may or may not be fully recoverable or insured), schedule and/or production delays, market volatility and 
other financial impacts. If any or all of these items were to occur, we could experience material adverse impacts on 
our business, financial position, results of operations and/or cash flows.

•

Our future success depends, in part, on our ability to innovate, develop new products and technologies, progress 
and benefit from digital transformation and maintain technologies, facilities and equipment to win new 
competitions and meet the needs of our customers. Failure to do so or meet our contractual obligations that 
require innovative design could adversely affect our profitability, reputation and future prospects.

We design, develop and manufacture technologically advanced and innovative products and services, which are 
applied by our customers in a variety of environments, including highly demanding operating conditions, to 
accomplish challenging missions. Our success depends upon our ability to develop technologically advanced, 
innovative and cost-effective products and services and market these products and services to our customers 
globally. Our ability to develop innovative and technologically advanced products depends on the talent of our 
workforce, continued funding for, and investment in, research and development projects, continued access to assured 
suppliers of important technologies and components, our ability to compete (including with commercial companies) 
and our ability to provide the people, technologies, facilities, equipment and financial capacity needed to develop 
and deliver those products and services with maximum efficiency. To perform on our contracts and to win new 
business, we also depend increasingly on our ability to progress successfully on our digital transformation. It is 
increasingly necessary to meet evolving customer requirements, to differentiate our offerings, and to achieve 
efficiencies that we and our suppliers/partners successfully develop digital based solutions and transform our 
operations. If we are unable to continue to develop new products and technologies in a timely fashion, and progress 
successfully to effect digital solutions and transformation, or if we fail to achieve market acceptance more rapidly 
than our competitors, we may be unable to maintain our competitive position and our future success could be 
materially adversely affected.

We aim to ensure that our technical solutions are responsibly developed, tested and operated. Problems and delays in 
the successful development and delivery of our solutions, including as a result of issues with our design, technology 
or operations, digital transformation, inability to achieve learning curve assumptions, artificial intelligence, 
manufacturing materials or components, or subcontractor (or other supplier) performance can prevent us from 
meeting requirements and create significant risk and liabilities. Similarly, failures to perform on schedule or 
otherwise to fulfill our contractual obligations can negatively impact our financial position, reputation and ability to 
win future business.

In addition, our products cannot be tested and proven in all situations and are otherwise subject to unforeseen 
problems that can negatively affect revenue, schedule and profitability, and result in loss of life or property. They 
include loss on launch or flight of spacecraft, loss of aviation platforms, premature failure of products that cannot be 
accessed for repair or replacement, unintended explosions, problems with design, quality and workmanship, country 
of origin of procured materials, inadequate supplier components and degradation of product performance. Factors 
that may affect revenue and profitability also include: inaccurate cost estimates, design issues, human factors, 
unforeseen costs and expenses, diversion of management focus, loss of follow-on work, replacement obligations, 
and repayment to the government customer of certain contract cost and fee payments previously received.

Certain contracts, primarily involving space satellite systems, contain provisions that entitle the customer to recover 
fees in the event of failure of the system upon launch or subsequent deployment for less than a specified period of 
time. Under such terms, we are generally required to forfeit fees previously recognized and/or collected.

If we are unable to meet our obligations, including due to issues regarding the design, development or manufacture 
of our products or services, or we experience launch, platform, satellite system or other failures, it could have a 
material adverse effect on our reputation, our ability to compete for other contracts and our financial position, results 
of operations and/or cash flows.

•

Our business is subject to disruption caused by natural disasters that could adversely affect our profitability and 
our overall financial position.

We have significant operations, including centers of excellence, located in regions that have been, and may in the 
future be, exposed to hurricanes, earthquakes, water levels, wildfires, windstorms, and other natural disasters. We 
expect our facilities, operations, employees and communities in the future, particularly at facilities in coastal areas 
and areas prone to extreme weather events and water scarcity to continue to be at risk for future natural disasters or 

-19-

NORTHROP GRUMMAN CORPORATION

other weather events (which may be exacerbated by climate change). Climate related changes can impact natural 
disasters, including weather patterns, with the increased frequency and severity of significant weather events (e.g., 
flooding, hurricanes and tropical storms), natural hazards (e.g., increased wildfire risk), rising mean temperature and 
sea levels, and long-term changes in precipitation patterns (e.g., drought, desertification, and/or poor water quality). 
If a natural disaster occurs, our operations could be interrupted, our employees could be impacted, we could incur 
significant costs and our performance could be adversely affected. Our subcontractors and other suppliers have also 
been, and may in the future be, subject to natural disasters that could cause disruption and affect their ability to 
deliver or perform. Disruptions also impact the availability and cost of materials needed for manufacturing and 
could increase insurance and other operating costs, or result in a lack of available coverage. Although we take steps 
to mitigate these risks, including considering them in determining where to put new businesses, the damage and 
disruption resulting from natural disasters, which may increase, as well as delays in recovery, may be significant.

If insurance or other sources are unavailable or insufficient to recover all costs or if we experience a significant 
disruption to our business due to a natural disaster, it could have a material adverse effect on our financial position, 
results of operations and/or cash flows.

• We provide products and services, including related to hazardous and high risk operations, which subjects us to 

various environmental, regulatory, financial, reputational and other risks.

We provide products and services related to hazardous and high risk operations. Among other such operations, our 
products and services are used in nuclear-related activities (including nuclear-powered platforms) and used in 
support of nuclear-related operations of third parties. In addition, certain of our products are provided with space and 
missile launches. We use and provide energetic materials, including in propulsion systems, which include products 
that involve highly explosive or flammable elements. We develop missile systems, and counter systems, including 
strategic deterrents, as well as subsystems and components. These and other activities subject us to various 
extraordinary risks, including (1) potential liabilities relating to nuclear or non-nuclear launch-related incidents, 
unintended initiation of energetic materials and explosions, including risk of personal injury, property damage and 
environmental harm; (2) harmful effects on the environment and human health that may result from nuclear-related 
activities, operations or incidents; the storage, handling and disposal of radioactive materials; and the development, 
testing and use of energetics, including in propulsion systems, and unintended explosions or releases and (3) to 
failed launches. We may be subject to reputational harm and potential liabilities arising out of such incidents or 
hazardous operations, whether or not the cause was within our control, and insurance may not be reasonably 
available. Under some circumstances, the U.S. government and prime contractors may provide for certain 
indemnification and other protection, including pursuant to, or in connection with, Public Law 85-804, 10 U.S.C. 
3861, the Price-Anderson Nuclear Industries Indemnity Act, the NASA Space Act, the Commercial Space Launch 
Act and the Terrorism Risk Insurance Reauthorization Act, for certain risks, but those protections may not be 
available or adequate.

Certain of our products, such as medium and large caliber ammunition and propulsion systems, involve the use, 
manufacture and/or handling of a variety of explosive and flammable materials or other hazardous substances. These 
activities have resulted and may result in incidents that cause workplace injuries and fatalities, the temporary shut 
down or other disruption of manufacturing, production delays, environmental harm and expense, fines and liabilities 
to third parties. We have safety and loss prevention programs, which provide for pre-construction reviews, along 
with safety audits of operations involving explosive materials, to attempt to mitigate some such incidents, as well as 
potentially insurance coverage and indemnification, but they may not be successful.

In addition, our customers may use our products and services in ways that can be unusually hazardous or risky, or in 
ways that are not intended, which may create potential liabilities for our company, as well as reputational harm. 

If any of these risks were to materialize (e.g. if there was a nuclear incident, or an incident related to launch 
activities or the use of energetics or propulsion systems), and if insurance coverage or indemnification or other 
protection was not fully available, it could adversely affect our reputation and have a material adverse effect on our 
financial position, results of operations and/or cash flows.

• We may be unable fully to exploit or adequately to protect intellectual property rights, which could materially 

affect our ability to compete, our reputation and our financial position, results of operations and/or cash flows.

To perform on our contracts and to win new business, we depend on our ability to develop, protect and exploit our 
intellectual property and also to access the intellectual property of others under reasonable terms. Increasing 
demands from our customers to access and obtain rights in our intellectual property, and positions taken by our 
suppliers and competitors challenge our ability to exploit, protect and access intellectual property.

-20-

NORTHROP GRUMMAN CORPORATION

We own many forms of intellectual property, including U.S. and foreign patents, trademarks, copyrights and trade 
secrets and we license or otherwise obtain access to various intellectual property rights of third parties. The U.S. 
government and certain foreign governments hold licenses or other rights to certain intellectual property that we 
develop in performance of government contracts, and at times seek to use or authorize others to use such intellectual 
property, including in competition with us and including where we do not believe they are entitled to do so. 
Governments continue to increase efforts to assert or obtain more extensive rights in intellectual property, which 
could reduce our ability to develop, protect and exploit certain of our intellectual property rights and to compete. 
Governments also decline at times to make intellectual property of others available to us under acceptable terms.

We rely significantly upon proprietary technology, information, processes and know-how. We typically seek to 
protect this information, including by entering into intellectual property agreements with our employees and other 
parties such as consultants, teammates and subcontractors. These agreements and other measures may not provide 
adequate protection for our trade secrets and other proprietary information. In the event of an infringement of such 
intellectual property rights, a breach of a confidentiality agreement, a misuse or theft of our intellectual property or 
divulgence of proprietary information, we may not have adequate legal remedies. In addition, our trade secrets or 
other proprietary information may otherwise become known or be independently developed by competitors.

In some instances, our ability to win or perform contracts requires us to use third party intellectual property. This 
may require the government or our customer to provide rights to such third party intellectual property, or that we are 
able to negotiate directly with third parties to obtain necessary rights on reasonable terms. That may not be 
practicable. 

Our intellectual property is subject to challenge, invalidation, misappropriation or circumvention by third parties. 
Our access to and use of intellectual property licensed or otherwise obtained from third parties is also subject to 
challenges. Litigation to determine the scope of intellectual property rights, even if ultimately successful, could be 
costly and could divert management’s attention. Moreover, the laws concerning intellectual property rights vary 
among countries and the protection provided to our intellectual property by foreign laws and courts may not be 
favorable.

If we are unable adequately to exploit our intellectual property rights, to protect our intellectual property rights, to 
obtain rights to intellectual property of others, it could have a material adverse effect on our reputation, ability to 
compete for and perform on contracts, financial position, results of operations and/or cash flows.

General and Other Risk Factors 

•

Our insurance coverage, customer indemnifications or other liability protections may be unavailable or 
inadequate to cover all of our significant risks, which could adversely affect our profitability and overall financial 
position.

We endeavor to obtain insurance from financially solid, responsible, highly rated counterparties in established 
markets to cover significant risks and liabilities (including, for example, natural disasters, space launches and on-
orbit operations, cyber security, hazardous operations, energetics and products liability). Not every risk or liability 
can be insured, and insurance coverage is not always reasonably available. The policy limits and terms of coverage 
reasonably obtainable may not be sufficient to cover actual losses or liabilities. For example, the space and property 
insurance markets are experiencing increased price volatility and capacity constraint. Due to recent increases in the 
frequency and severity of losses, insurers are decreasing limits, increasing pricing and some may exit the market. 
Even if insurance coverage is available, we are not always able to obtain it at a price or on terms acceptable to us or 
without increasing exclusions. Disputes with insurance carriers over the availability of coverage, and the insolvency 
of one or more of our insurers has affected and may continue to affect the availability or timing of recovery, as well 
as our ability to obtain insurance coverage at reasonable rates in the future. In some circumstances we may be 
entitled to certain legal protections or indemnifications from our customers through contractual provisions, laws or 
otherwise. However, these protections are not always available, are difficult to negotiate and obtain, are typically 
subject to certain terms or limitations, including the availability of funds, and may not be sufficient to cover our 
losses or liabilities. If insurance coverage, customer indemnifications and/or other legal protections are not available 
or are not sufficient to cover risks or losses, it could have a material adverse effect on our financial position, results 
of operations and/or cash flows. 

•

Pension and other postretirement benefit (OPB) obligations and related expenses and funding requirements may 
fluctuate significantly depending upon investment performance of plan assets, changes in actuarial assumptions, 
and legislative or other regulatory actions.

-21-

NORTHROP GRUMMAN CORPORATION

The company’s pension and OPB obligations and related expenses are dependent upon the investment performance 
of plan assets and various assumptions, including discount rates, mortality and the estimated long-term rates of 
return on plan assets. Changes in assumptions associated with our pension and OPB plans, investment performance 
of plan assets, and gains or losses associated with changes in valuation of marketable securities related to our non-
qualified plans and other non-operating assets could have a material adverse effect on our financial position, results 
of operations and/or cash flows.

Funding requirements for our pension plans, including Pension Benefit Guaranty Corporation premiums, are subject 
to legislative and other government regulatory actions. In accordance with government regulations, pension plan 
cost recoveries under our U.S. government contracts may occur in different periods from when they are recognized 
for financial statement purposes or when pension funding is made. These timing differences, as well as government 
challenges to pension and OPB cost recovery, could have a material adverse effect on our financial position, results 
of operations and/or cash flows. 

•

Business investments and/or recorded goodwill and other long-lived assets may become impaired, resulting in 
substantial losses and write-downs that would reduce our operating income.

Goodwill is an intangible asset that we recognize in connection with acquisitions of third-party businesses. Goodwill 
accounts for approximately 38 percent of our total assets as of December 31, 2023. Other long-lived assets 
principally comprise property, plant and equipment (PP&E) used in operating our business. The cost of PP&E 
utilized in support of our commercial business, including approximately $500 million of PP&E used in our 
commercial space business, is not allocable to government contracts and is therefore subject to greater recoverability 
risk than PP&E utilized in support of our U.S. government contracts. Although the fair value of our reporting units 
and the net realizable value of our other long-lived assets currently exceed their respective carrying values, changes 
in business conditions, the market-based inputs used in our goodwill impairment test, or our assumptions related to 
the recoverability of our long-lived assets, could result in significant write-offs of goodwill or other long-lived 
assets, which could have a material adverse effect on our financial condition and/or results of operations.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

We recognize the critical importance of maintaining the safety and security of our systems and data and have a 
holistic process for overseeing and managing cybersecurity and related risks. This process is supported by both 
management and our Board of Directors.

The Chief Information Office, which maintains our cybersecurity function, is led by our Chief Information Officer 
(CIO), who reports to our CEO. The Chief Information Security Officer (CISO) reports to the CIO and generally is 
responsible for management of cybersecurity risk and the protection and defense of our networks and systems. The 
CISO manages a team of cybersecurity professionals with broad experience and expertise, including in cybersecurity 
threat assessments and detection, mitigation technologies, cybersecurity training, incident response, cyber forensics, 
insider threats and regulatory compliance.

Our Board of Directors is responsible for overseeing our enterprise risk management activities in general, and each 
of our Board committees assists the Board in the role of risk oversight. The full Board receives an update on the 
Company’s risk management process and the risk trends related to cybersecurity at least annually. The Audit and 
Risk Committee specifically assists the Board in its oversight of risks related to cybersecurity. To help ensure 
effective oversight, the Audit and Risk Committee receives reports on information security and cybersecurity from 
the CISO at least four times a year.

In addition, the Company’s Enterprise Risk Management Council (ERMC) considers risks relating to cybersecurity, 
among other significant risks, and applicable mitigation plans to address such risks. The ERMC is comprised of the 
Executive Leadership Team, as well as the Chief Accounting Officer, Chief Compliance Officer, Corporate 
Secretary, Chief Sustainability Officer, Treasurer and Vice President, Internal Audit. The CIO and CISO attend each 
ERMC meeting. The ERMC meets during the year and receives periodic updates on cybersecurity risks from the 
CIO and CISO. We have an established process and playbook led by our CISO governing our assessment, response 
and notifications internally and externally upon the occurrence of a cybersecurity incident. Depending on the nature 
and severity of an incident, this process provides for escalating notification to our CEO and the Board (including our 
Lead Independent Director and the Audit and Risk Committee chair).

NORTHROP GRUMMAN CORPORATION

Our approach to cybersecurity risk management includes the following key elements:

• Multi-Layered Defense and Continuous Monitoring – We work to protect our computing environments and 
products from cybersecurity threats through multi-layered defenses and apply lessons learned from our 
defense and monitoring efforts to help prevent future attacks. We utilize data analytics to detect anomalies 
and search for cyber threats. Our Cybersecurity Operations Center provides comprehensive cyber threat 
detection and response capabilities and maintains a 24x7 monitoring system which complements the 
technology, processes and threat detection techniques we use to monitor, manage and mitigate 
cybersecurity threats. From time to time, we engage third party consultants or other advisors to assist in 
assessing, identifying and/or managing cybersecurity threats. We also periodically use our Internal Audit 
function to conduct additional reviews and assessments. 

•

•

•

•

•

Insider Threats – We maintain an insider threat program designed to identify, assess, and address potential 
risks from within our Company. Our program evaluates potential risks consistent with industry practices, 
customer requirements and applicable law, including privacy and other considerations.

Information Sharing and Collaboration – We work with government, customer, industry and/or supplier 
partners, such as the National Defense Information Sharing and Analysis Center and other government-
industry partnerships, to gather and develop best practices and share information to address cyber threats. 
These relationships enable the rapid sharing of threat and vulnerability mitigation information across the 
defense industrial base and supply chain.

Third Party Risk Assessments – We conduct information security assessments before sharing or allowing 
the hosting of sensitive data in computing environments managed by third parties, and our standard terms 
and conditions contain contractual provisions requiring certain security protections.  

Training and Awareness – We provide awareness training to our employees to help identify, avoid and 
mitigate cybersecurity threats. Our employees with network access participate annually in required training, 
including spear phishing and other awareness training. We also periodically host tabletop exercises with 
management and other employees to practice rapid cyber incident response.

Supplier Engagement – We provide training and other resources to our suppliers to support cybersecurity 
resiliency in our supply chain. We also require our suppliers to comply with our standard information 
security terms and conditions, in addition to any requirements from our customers, as a condition of doing 
business with us, and require them to complete information security questionnaires to review and assess 
any potential cyber-related risks depending on the nature of the services being provided. 

While we have experienced cybersecurity incidents in the past, to date none have materially affected the Company 
or our financial position, results of operations and/or cash flows. We continue to invest in the cybersecurity and 
resiliency of our networks and to enhance our internal controls and processes, which are designed to help protect our 
systems and infrastructure, and the information they contain. For more information regarding the risks we face from 
cybersecurity threats, please see “Risk Factors.”

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW
The following discussion should be read along with the financial statements included in this Form 10-K, as well as 
Part II, “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations” of our 
Form 10-K for the year ended December 31, 2022 (“2022 Annual Report on Form 10-K”).

Global Security Environment
The U.S. and its allies continue to face a global security environment of heightened tensions and instability, threats 
from state and non-state actors, including in particular major global powers, as well as terrorist organizations, 
increasing nuclear tensions, diverse regional security concerns and political instability. The market for defense 
products, services and solutions globally is driven by these complex and evolving security challenges, considered in 
the broader context of political and socioeconomic circumstances and priorities. Our operations and financial 
performance, as well as demand for our products and services, are impacted by global events, including violence and 
unrest. The same is true for our suppliers and other business partners.

The conflict in Ukraine has increased global tensions and instability, highlighted threats and increased global 
demand, as well as further disrupted global supply chains. We continue to not anticipate significant adverse financial 
impacts directly from the ongoing conflict. We have experienced, and, while difficult to predict, may continue to 
experience a modest increase in demand for certain of our goods and services directly and indirectly related to the 
conflict in Ukraine, either through direct sales or if the U.S. provides increased military assistance and support to 
Ukraine.

More recently, the hostilities in Israel and the Gaza Strip have further heightened global tensions and instability. At 
this time, it is unknown whether hostilities in this region will escalate into an even larger conflict. The demand for 
our goods and services may increase, especially if the U.S. provides increased military assistance and support to 
Israel. We do not have a significant business presence in the region, and therefore do not anticipate significant 
adverse financial impacts directly from the current conflict.

More broadly, the ongoing conflicts in Ukraine and Israel and threats elsewhere, particularly in the Pacific region, 
have heightened tensions and highlighted security requirements globally, including Europe, the Middle East and the 
Pacific region, as well as the U.S. These conflicts may result in increased demand for defense products and services 
from allies and partner nations, particularly in those areas. We are actively exploring both opportunities and risks 
associated with the broader global security environment.

We believe the current global security environment highlights the significant national security threats to the U.S. and 
its allies, and the need for strong deterrence and a robust defense capability. We believe our capabilities, particularly 
in space, C4ISR, missile defense, battle management, advanced weapons, and survivable aircraft and mission 
systems should help our customers in the U.S. and globally defend against current and future threats and, as a result, 
continue to allow for long-term profitable business growth.

Global Economic Environment
The global economic environment has experienced extraordinary challenges, including high rates of inflation and 
inflationary pressures; widespread delays and disruptions in supply chains; business slowdowns or shutdowns; 
workforce challenges and labor shortfalls; and market volatility. Some of these challenges were due, in part, to the 
global health emergency caused by COVID-19, which the World Health organization declared ended in May 2023. 
Direct impacts of COVID-19 on our business during 2023 were limited, and we are not currently expecting 
significant direct impacts on our business going forward. 

The macroeconomic factors have contributed, and we expect will continue to contribute, to increased costs, delays, 
disruptions and other performance challenges, as well as increased competing demands for limited resources to 
address such increased costs and other challenges, for our company, our suppliers and partners, and our customers. 

We continue to work hard to mitigate challenges caused by the current macroeconomic environment on our 
business, including by taking steps to support our suppliers and small businesses and enhancing our workforce 
through extensive hiring, development and retention efforts. However, the broader macroeconomic environment, 
including inflationary pressures and supply chain challenges, continued adversely to affect the company’s results for 
the year ended December 31, 2023. We cannot clearly predict how long these macroeconomic challenges will 
continue, how they will change over time, or what additional resources will be available, but we expect to see this 
challenging macroeconomic environment continue adversely to impact the global economy, our customers and 
suppliers, our industry and our company in 2024.

In addition, increased interest rates, raising the cost of borrowing for governments, could further impact government 
spending priorities (in the U.S. and allied countries, in particular), including their demand for defense products. 
Economic tensions and changes in international trade policies, including higher tariffs on imported goods and 
materials and renegotiation of free trade agreements, could also further impact the global market for defense 
products, services and solutions.

U.S. Political, Budget and Regulatory Environment
The U.S. continues to face an uncertain and evolving political, budget and regulatory environment. In particular, it is 
difficult to predict the specific course of future defense budgets. Current and future requirements related to the 
conflicts in Ukraine and Israel, threats in the Pacific regions and other security priorities, as well as global inflation, 
the national debt, and other domestic priorities, among other things, in the U.S. and globally, will continue to impact 
our customers’ budgets, spending and priorities, and our industry. The U.S. political environment, including the U.S. 
election cycle, may also impact defense budgets and priorities, issues related to the national debt, and government 
spending more broadly. We anticipate that issues related to budgetary priorities and defense spending levels, the 
debt ceiling, and the spending caps imposed by the Fiscal Responsibility Act of 2023 (FRA), particularly with 
respect to discretionary spending, will continue to be a subject of considerable debate, with a potentially significant 
impact on our programs and the company.

Annual appropriations to fund the federal government for FY 2024 have not been enacted. Congress continues to 
pass short-term continuing resolutions (CR) to fund the federal government. The most recent “laddered” CR passed 
in January 2024 funds the government through March 2024, depending on the appropriation bill. If Congress does 
not pass full year appropriations or an additional CR before current funding expires, the federal government (or 
select departments) could face a shutdown and cease what are characterized as certain non-essential operations. 
Depending on the nature and duration of a potential shutdown, businesses that rely on government funding, 
including defense contractors, could be significantly impacted. If the federal government remains under a CR at the 
end of April 2024, the one percent discretionary spending cuts under the FRA could be triggered, potentially 
resulting in lower funding on the programs in which we participate.

In December 2023, the president signed the National Defense Authorization Act (NDAA) for FY 2024 which 
supports approximately $886 billion in FY 2024 funding for national defense, $842 billion of which is for the DoD. 

The political environment, federal budget, debt ceiling and regulatory environment are expected to continue to be 
the subject of considerable debate, especially in light of the ongoing conflicts and heightened global tensions, the 
inflationary environment and political tensions. The results of those debates could have material impacts on defense 
spending broadly and the company’s programs in particular. We anticipate that the broader macroeconomic 
environment, with ongoing inflationary pressures, pockets of labor challenges, and supply chain disruption, among 
other considerations, will continue to play a significant role in the outcome of these debates and, in turn, on our 
industry and company.

For further information on the global security and economic environment and U.S. political, budget and regulatory 
environment, including the risks related thereto, see “Liquidity and Capital Resources,” “Quantitative and 
Qualitative Disclosures About Market Risks” and “Risks Factors” included in this Form 10-K.

Ground-Based Strategic Deterrent (“GBSD” or “Sentinel”) Program Nunn-McCurdy Breach Review
Due in part to the impact of macroeconomic factors, in January 2024 the customer provided congressional 
notification that the Sentinel program is currently under a Nunn-McCurdy breach review, which is required when 
total program cost estimates exceed certain defined thresholds. This notification, which has been driven primarily by 
increases in construction and procurement cost projections for the Production and Deployment phases, commences 
the process to achieve recertification for continuance of the program and update its baseline cost estimates. We are 
currently executing under a cost-type contract for the Engineering and Manufacturing Development phase, and the 
Production and Deployment phases are yet to be priced and negotiated. We are continuing to partner with our 
customer to address this critical mission. For more information, see “Risk Factors”.

Disposition of IT and Mission Support Services Business
Effective January 30, 2021 (the “Divestiture date”), we completed the sale of our IT and mission support services 
business (the “IT services divestiture”) for $3.4 billion in cash and recorded a pre-tax gain of $2.0 billion. The IT 
and mission support services business was comprised of the majority of the former Information Solutions and 
Services (IS&S) division of Defense Systems (excluding the Vinnell Arabia business); select cyber, intelligence and 
missions support programs, which were part of the former Cyber and Intelligence Mission Solutions (CIMS) 
division of Mission Systems; and the former Space Technical Services business unit of Space Systems. Operating 
results include sales and operating income for the IT and mission support services business prior to the Divestiture

date; therefore, no sales and operating income were recognized for this business during the years ended December 
31, 2023 and 2022. The company recorded sales of $162 million and pre-tax profit of $20 million for the IT and 
mission support services business during the year ended December 31, 2021.

Operating Performance Assessment and Reporting
We manage and assess our business based on our performance on contracts and programs (typically larger contracts 
or two or more closely-related contracts). We recognize sales from our portfolio of long-term contracts as control is 
transferred to the customer, primarily over time on a cost-to-cost basis (cost incurred relative to costs estimated at 
completion). As a result, sales tend to fluctuate in concert with costs incurred across our large portfolio of contracts. 
Due to the applicable FAR and CAS requirements that govern our U.S. government business, most types of costs are 
allocable to U.S. government contracts. As such, we do not focus on individual cost groupings (such as 
manufacturing, engineering and design labor, subcontractor, material, overhead and general and administrative 
(G&A) costs), as much as we do on total contract cost, which is the key driver of our sales and operating income.

In evaluating our operating performance, we primarily focus on changes in sales and operating margin rates. Where 
applicable, significant fluctuations in operating performance attributable to individual contracts or programs, or 
changes in a specific cost element across multiple contracts, are described in our analysis. Based on this approach 
and the nature of our operations, the discussion of results of operations below first focuses on our four segments 
before distinguishing between products and services. Changes in sales are generally described in terms of volume, 
while changes in operating margin rates are generally described in terms of performance and/or contract mix. For 
purposes of this discussion, volume generally refers to increases or decreases in sales or cost from production/
service activity levels and performance generally refers to non-volume-related changes in profitability, which are 
typically described in terms of changes in net EAC adjustments. Contract mix generally refers to changes in the ratio 
of contract type and/or life cycle (e.g., cost-type, fixed-price, development, production, and/or sustainment).

CONSOLIDATED OPERATING RESULTS

For purposes of the operating results discussion below, we assess our performance using certain financial measures 
that are not calculated in accordance with accounting principles generally accepted in the United States of America 
(“GAAP” or “FAS”). 

Mark-to-market adjusted net earnings (MTM-adjusted net earnings) and MTM-adjusted earnings per share (MTM-
adjusted EPS) exclude MTM pension and OPB (expense)/benefit and related tax impacts, which are generally only 
recognized during the fourth quarter. Transaction-adjusted net earnings and transaction-adjusted earnings per share 
(transaction-adjusted EPS) exclude the MTM impacts noted above, as well as impacts related to the IT services 
divestiture, including the gain on sale of the business, associated federal and state income tax expenses, transaction 
costs, and the make-whole premium for early debt redemption. These non-GAAP measures may be useful to 
investors and other users of our financial statements as supplemental measures in evaluating the company’s 
underlying financial performance by presenting the company’s operating results before the non-operational impact 
of pension and OPB actuarial gains and losses, and with regard to transaction-adjusted net earnings and EPS, the 
impact of certain divestiture activity. These measures are also consistent with how management views the 
underlying performance of the business as the impact of MTM accounting and the IT services divestiture are not 
considered in management’s assessment of the company’s operating performance or in its determination of incentive 
compensation awards. 

We reconcile these non-GAAP financial measures to their most directly comparable GAAP financial measures 
below. These non-GAAP measures may not be defined and calculated by other companies in the same manner and 
should not be considered in isolation or as an alternative to operating results presented in accordance with GAAP.

Sales
2023 sales increased $2.7 billion, or 7 percent, due to higher sales at all four sectors. 2023 sales reflect continued 
strong demand for our products and services.

See “Segment Operating Results” below for further information by segment and “Product and Service Analysis” for 
product and service detail. See Note 16 to the consolidated financial statements for information regarding the 
company’s sales by customer type, contract type and geographic region for each of our segments.

Operating Income and Margin Rate
2023 operating income decreased $1.1 billion, or 30 percent, primarily due to a $1.56 billion charge on the B-21 
program at Aeronautics Systems, partially offset by higher operating income at Space Systems and Defense 
Systems. The B-21 charge relates to the low-rate initial production (LRIP) phase of the program and is due 
principally to a change in our assumptions regarding funding to mitigate the impact of macroeconomic disruptions 
on the program and higher projected manufacturing costs that reflect recent supplier negotiations and our experience 
in completing the first aircraft. The decrease was also offset by $311 million of lower unallocated corporate expense, 
largely due to higher deferred state tax benefits associated with the MTM adjustment and B-21 charge and lower 
intangible asset amortization and PP&E step-up depreciation, as well as a $118 million reduction in the FAS/CAS 
operating adjustment. 2023 operating margin rate declined to 6.5 percent from 9.8 percent reflecting the items 
above.

2023 G&A costs as a percentage of sales decreased to 10.2 percent from 10.6 percent, primarily due to higher sales, 
which more than offset our continued investments for future business opportunities.

For further information regarding product and service operating costs and expenses, see “Product and Service 
Analysis” below.

The 2023 MTM expense of $422 million was primarily driven by a 39 basis point decrease in the discount rate from 
year end 2022, partially offset by actual net plan asset returns of 11.1 percent compared to our 7.5 percent asset 
return assumption.

Federal and Foreign Income Taxes
The 2023 effective tax rate (ETR) decreased to 12.4 percent from 16.1 percent in 2022 primarily due to lower 
earnings before income taxes as a result of the B-21 charge and MTM expense, which collectively reduced the 2023 
ETR by 3.8 percentage points. The 2022 MTM benefit increased the 2022 ETR by 1.2 percentage points. See Note 7

in operating income described above, partially offset by a $650 million decrease in income tax expense, a

SEGMENT OPERATING RESULTS

Basis of Presentation
The company is aligned in four operating sectors, which also comprise our reportable segments: Aeronautics 
Systems, Defense Systems, Mission Systems and Space Systems. For a more complete description of each 
segment’s products and services, see “Business.”

Segment Operating Income and Margin Rate
Segment operating income, as reconciled in the table below, and segment operating margin rate (segment operating 
income divided by sales) are non-GAAP measures that reflect the combined operating income of our four segments 
less the operating income associated with intersegment sales. Segment operating income includes pension expense 
allocated to our sectors under FAR and CAS and excludes FAS pension service expense and unallocated corporate 
items (certain corporate-level expenses, which are not considered allowable or allocable under applicable FAR and 
CAS requirements, and costs not considered part of management’s evaluation of segment operating performance). 
These non-GAAP measures may be useful to investors and other users of our financial statements as supplemental 
measures in evaluating the financial performance and operational trends of our sectors. These measures may not be

Segment Operating Income and Margin Rate
2023 segment operating income decreased $1.5 billion, or 35 percent, and segment operating margin rate decreased 
to 7.0 percent primarily due to the B-21 charge at Aeronautics Systems. Operating income at Space Systems and 
Defense Systems was higher than in the prior year period.

FAS/CAS Operating Adjustment
The decrease in our 2023 FAS/CAS operating adjustment is primarily due to lower FAS pension service expense 
resulting from changes in certain actuarial assumptions as of December 31, 2022.

Unallocated Corporate Expense (Income)
The decrease in 2023 unallocated corporate expense is primarily due to higher deferred state tax benefits associated 
with the MTM adjustment and B-21 charge and lower intangible asset amortization and PP&E step-up depreciation.

Net Estimate-At-Completion (EAC) Adjustments - We record changes in estimated contract earnings at completion

Sales
2023 sales increased $255 million, or 2 percent, primarily due to higher volume on restricted programs, partially 
offset by a $191 million decrease on the F/A-18 program largely due to post Multi-Year Procurement 4 (MYP4) 
contract award timing, a $131 million decrease on the Joint Surveillance and Target Attack Radar System (JSTARS) 
program as that program nears completion and a decrease on the E-2 program largely related to higher material 
volume in the prior year.

Operating Income
2023 operating income decreased $1.6 billion and operating margin rate decreased to (4.4) percent primarily due to 
the previously described $1.56 billion charge recorded on the LRIP phase of the B-21 program, inclusive of a 
$143 million unfavorable EAC adjustment for the first LRIP lot. The prior year period includes $133 million of 
favorable EAC adjustments on the engineering, manufacturing and development phase of the B-21 program and a 
$38 million gain on a property sale. Apart from the B-21 EAC adjustments noted above, net EAC adjustments across 
the sector were $58 million higher than in the prior year.

Sales
2023 sales increased $283 million, or 5 percent, primarily due to higher volume on several programs, including 
ammunition programs, Guided Multiple Launch Rocket System (GMLRS), an international training program, 
Hypersonic Attack Cruise Missile (HACM), and Stand-in Attack Weapon (SiAW).

Operating Income
2023 operating income increased $46 million, or 7 percent, due to higher sales and a higher operating margin rate. 
Operating margin rate increased to 12.1 percent from 11.9 percent primarily due to the write-down of an 
unconsolidated joint venture investment in the prior year.

Sales
2023 sales increased $499 million, or 5 percent, primarily due to higher restricted sales on advanced 
microelectronics programs, as well as a $165 million increase on marine systems programs. These increases were 
partially offset by a $107 million decrease on the Ground/Air Task Oriented Radar (G/ATOR) program largely 
driven by the timing of material receipts and full-rate production (FRP) 5 contract award, as well as lower volume 
on airborne radar programs.

Operating Income
2023 operating income decreased $9 million, or 1 percent, due to a lower operating margin rate, which more than 
offset higher sales. Operating margin rate decreased to 14.8 percent from 15.6 percent primarily due to a prior year 
$33 million benefit recognized in connection with a contract-related legal matter, as well as changes in contract mix 
toward more cost-type content.

Operating Income
2023 operating income increased $54 million, or 5 percent, due to higher sales, partially offset by a lower operating 
margin rate. Operating margin rate decreased to 8.7 percent from 9.4 percent primarily due to a prior year 
$96 million gain recognized in connection with a land exchange transaction, as well as lower net EAC adjustments 
driven by $100 million of unfavorable EAC adjustments on the HALO program in 2023. These decreases were 
partially offset by a $42 million benefit from insurance recoveries in our commercial space business during 2023.

Product Sales and Costs
2023 product sales increased $2.4 billion, or 8 percent, due to an increase in product sales at all four sectors. The 
increase was principally driven by higher volume on restricted programs, GBSD and NGI at Space Systems, higher 
restricted sales at Mission Systems and Aeronautics Systems, and higher volume on ammunition programs, 
GMLRS, IBCS and HACM at Defense Systems.

2023 product costs increased $4.0 billion, or 16 percent, consistent with the higher product sales described above 
and reflect a lower operating margin rate principally due to the previously described $1.56 billion charge on the 
B-21 program at Aeronautics Systems and lower net EAC adjustments on Space Systems production programs.

Service Sales and Costs
2023 service sales increased $313 million, or 4 percent, due to an increase in service sales at all four sectors. The 
increase was principally driven by higher restricted sales at Space Systems and Aeronautics Systems, higher volume 
on restricted programs and F-35 sustainment at Mission Systems, and higher volume on an international training 
program at Defense Systems.

BACKLOG

Backlog represents the future sales we expect to recognize on firm orders received by the company and is equivalent 
to the company’s remaining performance obligations at the end of each period. It comprises both funded backlog 
(firm orders for which funding is authorized and appropriated) and unfunded backlog. Unexercised contract options 
and indefinite delivery indefinite quantity (IDIQ) contracts are not included in backlog until the time the option or 
IDIQ task order is exercised or awarded. Backlog is converted into sales as costs are incurred or deliveries are made.

Backlog consisted of the following at December 31, 2023 and 2022:

at Aeronautics Systems and Mission Systems), $1.7 billion for E-2, $1.5 billion for Triton, $1.4 billion for SDA 
Tranche 2 Transport Layer, and $0.8 billion for GMLRS.

Subsequent Event – In January 2024, the company received a termination for convenience in our restricted Space 
business. The company expects to reduce backlog by approximately $2 billion during the first quarter of 2024 
related to the termination.

LIQUIDITY AND CAPITAL RESOURCES

We are focused on the efficient conversion of operating income into cash to provide for the company’s material cash 
requirements, including working capital needs, satisfaction of contractual commitments, funding of our pension and 
OPB plans, investment in our business through capital expenditures, and shareholder return through dividend 
payments and share repurchases. 

As of December 31, 2023, we had cash and cash equivalents of $3.1 billion; $277 million was held outside of the 
U.S. by foreign subsidiaries. We expect cash and cash equivalents and cash generated from operating activities, 
supplemented by borrowings under credit facilities, commercial paper and/or in the capital markets through our shelf 
registration with the SEC, if needed, to be sufficient to provide liquidity to the company in the short-term and long-
term. The company has a five-year senior unsecured credit facility in an aggregate principal amount of $2.5 billion, 
and in April 2023, we renewed our one-year $500 million uncommitted credit facility. At December 31, 2023, there 
were no borrowings outstanding under these credit facilities. In February 2023, we issued $2.0 billion of unsecured 
senior notes for general corporate purposes, including debt repayment, share repurchases and working capital. 

The company’s principal contractual commitments include purchase obligations, repayments of long-term debt and 
related interest, and payments under operating leases. At December 31, 2023, we had $20.7 billion of purchase 
obligations, approximately half of which is short-term. Purchase obligations are largely comprised of open purchase 
order commitments to suppliers and subcontractors under U.S. government contracts. In most circumstances, our 
risk associated with the purchase obligations on our U.S. government contracts is limited to the termination liability 
provisions within those contracts. As such, we do not believe they represent a material liquidity risk to the company. 
At December 31, 2023, we had capital expenditure commitments of $1.4 billion, which we expect to satisfy with 
cash on hand. We also had provisions for uncertain tax positions of $2.0 billion, some or all of which could result in 
future cash payments to various taxing authorities. At this time, we are unable to estimate the timing and amount of 
any future cash outflows related to these uncertain tax positions.

repurchase programs (Note 3), commercial paper, credit facilities and long-term debt (Note 10), standby letters of

credit and guarantees (Note 12), future minimum contributions for the company’s pension and OPB plans (Note 13), 
and lease payment obligations (Note 15). 

Internal Revenue Code (IRC) Section 174
Beginning in 2022, the Tax Cuts and Jobs Act of 2017 (“TCJA”) eliminated the option to deduct research and 
development expenditures in the current year and requires taxpayers to amortize them over five years pursuant to 
IRC Section 174. Our 2022 cash from operations were reduced by approximately $900 million for federal estimated 
tax payments we made related to Section 174. As we finalized our 2022 federal tax return along with our continued 
analysis of research and development expenditures, we reduced the previously estimated impact of Section 174 on 
our tax liability for 2022 and 2023 to approximately $700 million and $500 million, respectively. Congress is 
considering legislation that would defer the amortization requirement to later years, possibly with retroactive effect. 
In the meantime, we expect to continue to make additional federal tax payments based on the current Section 174 tax 
law. The impact of Section 174 on our cash from operations depends on the amount of research and development 
expenditures incurred by the company and whether the IRS issues guidance on the provision which differs from our 
current interpretation, among other things.

Cash Flow Measures
In addition to our cash position, we consider various cash flow measures in capital deployment decision-making, 
including cash provided by operating activities and adjusted free cash flow, a non-GAAP measure described in more 
detail below.

2023 cash provided by operating activities increased $974 million, or 34 percent, principally due to improved trade 
working capital largely driven by increased billings and cash collections, partially offset by higher supplier 
payments.

Adjusted Free Cash Flow
Adjusted free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash provided by 
or used in operating activities, less capital expenditures, plus proceeds from the sale of equipment to a customer (not 
otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary 
pension contributions, if any. Adjusted free cash flow includes proceeds from the sale of equipment to a customer as 
such proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary 
pension contributions for consistency and comparability of financial performance. This measure may not be defined 
and calculated by other companies in the same manner. We use adjusted free cash flow as a key factor in our 
planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP 
measure may be useful to investors and other users of our financial statements as a supplemental measure of our 
cash performance, but should not be considered in isolation, as a measure of residual cash flow available for 
discretionary purposes, or as an alternative to operating cash flows presented in accordance with GAAP.

repurchases and dividends totaled $2.6 billion in each period.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our consolidated financial statements are prepared in conformity with GAAP, which requires us to make estimates 
and assumptions about future events that affect the amounts reported in our consolidated financial statements. We 
employ judgment in making our estimates in consideration of historical experience, currently available information 
and various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ 
from our estimates and assumptions, and any such differences could be material to our consolidated financial 
statements. We believe the following accounting policies are critical to the understanding of our consolidated 
financial statements and require the use of significant management judgment in their application. For a summary of 
our significant accounting policies, see Note 1 to the consolidated financial statements.

Revenue Recognition
Due to the long-term nature of our contracts, we generally recognize revenue over time using the cost-to-cost 
method, which requires us to make reasonably dependable estimates regarding the revenue and cost associated with 
the design, manufacture and delivery of our products and services. 

Contract sales may include estimates of variable consideration, including cost or performance incentives (such as 
award and incentive fees), un-priced change orders, REAs and contract claims. Variable consideration is included in 
total estimated sales to the extent it is probable that a significant reversal in the amount of cumulative revenue 
recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. 
We estimate variable consideration as the most likely amount to which we expect to be entitled.

Our cost estimation process is based on the professional knowledge of our engineering, program management and 
financial professionals, and draws on their significant experience and judgment. We prepare EACs for our contracts 
and calculate an estimated contract profit based on total estimated contract sales and cost. Since our contracts often 
span a period of several years, estimation of revenue, cost, and progress toward completion requires the use of 
judgment. Factors considered in these estimates include our historical performance, the availability, productivity and 
cost of labor, the nature and complexity of work to be performed, the effect of change orders, availability and cost of 
materials, components and subcontracts, the effect of any delays in performance and the level of indirect cost 
allocations. 

We also consider the impact of macroeconomic factors on our estimates, in particular on contract EACs that span 
several years. For example, during 2023, we included in our EACs management’s best estimate of the impact 
inflation has had and may continue to have on our contracts. We also included our current best estimate of the 
impact on our EACs of disruptions we have experienced and continue to experience in the supply chain. The 
volatility of the recent macroeconomic environment has added complexity to our estimation process and may result 
in our year end 2023 contract EACs having more variability in the future than they might otherwise have had if the 
estimates had been prepared in a more stable macroeconomic environment.

NORTHROP GRUMMAN CORPORATION

We generally review and reassess our sales, cost and profit estimates for each significant contract at least annually or 
more frequently as determined by the occurrence of events, changes in circumstances and evaluations of contract 
performance to reflect the latest reliable information available. These assessments require judgments and estimates 
that can be affected by any number of these factors over time, which may cause actual results to differ materially 
from those estimates as facts and circumstances change or become known to us.

The company performs on a broad portfolio of long-term contracts, including the development of complex and 
customized military platforms and systems, as well as advanced electronic equipment and software, that often 
include technology at the forefront of science. Cost estimates on fixed-price development contracts and early-stage/
low-rate production contracts are inherently more uncertain as to future events than on mature, full-rate production 
contracts. As a result, there is typically more variability in those estimates and greater financial risk associated with 
unanticipated cost growth on fixed-price development contracts and early-stage/low-rate production contracts. 
Changes in estimates occur for a variety of reasons, including changes in contract scope, the resolution of risk at 
lower or higher cost than anticipated, unanticipated performance and other risks affecting contract costs, 
performance issues with subcontractors or suppliers, changes in indirect cost allocations, such as overhead and G&A 
costs, and changes in estimated award and incentive fees. Identified risks typically include technical, schedule and/or 
performance risk based on our evaluation of the contract effort. Similarly, the changes in estimates may include 
changes in, or resolution of, identified opportunities for operating margin improvement.

For the impacts of changes in estimates on our consolidated statements of earnings and comprehensive income, see 
“Segment Operating Results” and Note 1 to the consolidated financial statements.

Retirement Benefits
Overview – The determination of projected benefit obligations, the fair value of plan assets, and pension and OPB 
expense for our retirement benefit plans requires the use of estimates and actuarial assumptions. We perform an 
annual review of our actuarial assumptions in consultation with our actuaries. When we determine changes in the 
assumptions are warranted, or as a result of plan amendments, future pension and OPB expense and our projected 
benefit obligation could increase or decrease materially. The principal estimates and assumptions that have a 
significant effect on our consolidated financial position and annual results of operations are the discount rate, cash 
balance crediting rate, expected long-term rate of return on plan assets, estimated fair market value of plan assets, 
and the mortality rate of those covered by our pension and OPB plans. The effects of actual results differing from 
our assumptions and the effects of changing assumptions (i.e., actuarial gains or losses) are recognized immediately 
through earnings upon annual remeasurement in the fourth quarter, or on an interim basis as triggering events 
warrant remeasurement. 

Discount Rate – The discount rate represents the interest rate used to determine the present value of future cash 
flows currently expected to be required to settle our pension and OPB obligations. The discount rate is generally 
based on the yield of high-quality corporate fixed-income investments. At the end of each year, we determine the 
discount rate using a theoretical bond portfolio model of bonds rated AA or better to match the notional cash 
outflows related to projected benefit payments for each of our significant benefit plans. Taking into consideration 
the factors noted above, our weighted-average composite pension discount rate was 5.15 percent at December 31, 
2023 and 5.54 percent at December 31, 2022.

The effects of a hypothetical change in the discount rate may be nonlinear and asymmetrical for future years as the 
discount rate changes. Holding all other assumptions constant, an increase or decrease of 25 basis points in the 
December 31, 2023 discount rate assumption would have the following estimated effects on 2023 pension and OPB 
obligations, which would be reflected in the 2023 MTM expense (benefit), and 2024 expected pension and OPB 
expense:

Cash Balance Crediting Rate – A portion of the company’s pension obligation and resulting pension expense is 
based on a cash balance formula, where participants’ hypothetical account balances are accumulated over time with 
pay-based credits and interest. Interest is credited monthly using the current 30-Year Treasury bond rate. The 
interest crediting rate is part of the cash balance formula and independent of actual pension investment returns. The 
cash balance crediting rate used for FAS purposes tends to move in concert with the discount rate but has an 
offsetting effect on pension benefit obligations and the related MTM expense (benefit). The minimum cash balance 
crediting rate allowed under the plan is 2.25 percent. The cash balance crediting rate assumption has been set to 4.02 
percent for all years. Holding all other assumptions constant, an increase or decrease of 25 basis points in the 
December 31, 2023 cash balance crediting rate assumption would have the following estimated effects on the 2023 
pension benefit obligation, which would be reflected in the 2023 MTM expense (benefit), and 2024 expected

Expected Long-Term Rate of Return on Plan Assets – The expected long-term rate of return on plan assets (EROA) 
assumption reflects the average rate of net earnings we expect on current and future benefit plan investments. EROA 
is a long-term assumption, which we review annually and adjust to reflect changes in our long-term view of 
expected market returns and/or significant changes in our plan asset investment policy. Due to the inherent 
uncertainty of this assumption, we consider multiple data points at the measurement date including the plan’s target 
asset allocation, historical plan asset returns and third party projection models of expected long-term returns for each 
of the plans’ strategic asset classes. In addition to the data points themselves, we consider trends in the data points, 
including changes from the prior measurement date. The EROA assumptions we use for pension benefits are 
consistent with those used for OPB plans; however, we reduce the EROA for OPB plans to allow for the impact of 
tax on investment earnings, as certain Voluntary Employee Beneficiary Association trusts are taxable.

During 2023, the Investment Committee of the company’s benefit plans reviewed the plans’ major asset class 
allocations and approved an update to increase the target fixed-income asset allocation from 40% to 43%. The 
current asset allocation is now approximately 42% fixed-income, 27% public equities, 28% alternatives and 3% 
cash. At this time, the Investment Committee is not planning any significant changes to that mix. For further 
information on plan asset investments, see Note 13 to the consolidated financial statements.

While historical market returns are not necessarily predictive of future market returns, given our long history of plan 
performance supported by the stability in our investment mix, investment managers, and active asset management, 
we believe our actual historical performance is a reasonable metric to consider when developing our EROA. Our 
average annual rate of return from 1976 to 2023 was approximately 10.7 percent and our 20-year and 30-year rolling 
average rates of return were approximately 7.9 percent and 8.7 percent, respectively, each determined on an 
arithmetic basis and net of expenses. Our 2023 return on plan assets, net of expenses, were approximately 11.1 
percent.

Consistent with our past practice, we obtained long-term capital market forecasting models from several third parties 
and, using our target asset allocation, developed an expected rate of return on plan assets from each model. We 
considered not only the specific returns projected by those third party models, but also changes in the models year-
to-year when developing our EROA.

For determining 2023 FAS expense, we assumed an expected long-term rate of return on pension plan assets of 7.5 
percent and an expected long-term rate of return on OPB plan assets of 7.23 percent. For 2024 FAS expense, we 
have assumed an expected long-term rate of return on pension plan assets of 7.5 percent and 7.12 percent on OPB 
plans. Holding all other assumptions constant, an increase or decrease of 25 basis points in our December 31, 2023 
EROA assumption would have the following estimated effects on 2024 expected pension and OPB expense:

Estimated Fair Market Value of Plan Assets – For certain plan assets where the fair market value is not readily 
determinable, such as real estate, private equity, hedge funds and opportunistic investments, we develop estimates of 
fair value using the best information available. Estimated fair values on these plan assets are based on redemption 
values and net asset values (NAV), as well as valuation methodologies that include third party appraisals, 
comparable transactions, discounted cash flow valuation models and public market data.

Mortality Rate – Mortality assumptions are used to estimate life expectancies of plan participants. In October 2014, 
the Society of Actuaries Retirement Plans Experience Committee (RPEC) issued updated mortality tables and a 
mortality improvement scale, which reflected longer life expectancies than previously projected. In October 2019, 
the RPEC issued an updated mortality base table (the Private Retirement Plans Mortality table for 2012 (Pri-2012)), 
which we adopted after reviewing our own historical mortality experience. In October 2021, the RPEC released a 
new projection scale (MP-2021) that included additional underlying data for 2019, which included an increase in life 
expectancies relative to the prior year.

The RPEC did not release a MP-2022 or MP-2023 projection scale citing complexities in incorporating the 
substantial number of “excess deaths” in 2020 into their existing model and uncertainties about future expectations 
primarily related to COVID-19. As such, after considering the information released by the RPEC in October 2021 as 
well as the company’s recent mortality experience, we adopted the full MP-2021 projection scale while continuing 
to use the Pri-2012 White Collar table, supplemented with 50% of the Gradual Wear-Off illustration as outlined in 
the RPEC’s 2022 Mortality Improvement Update paper to reflect the future impacts of COVID-19, to develop our 
mortality assumptions used in calculating our pension and OPB obligations recognized at December 31, 2023, and 
the amounts estimated for our 2024 pension and OPB expense.

For further information regarding our pension and OPB plans, see “Risk Factors” and Notes 1 and 13 to the 
consolidated financial statements.

Litigation, Commitments and Contingencies
We are subject to a range of claims, disputes, enforcement actions, investigations, lawsuits, overhead cost claims, 
environmental matters, income tax matters and administrative proceedings that arise in the ordinary course of 
business. Estimating liabilities and costs associated with these matters requires judgment based upon the 
professional knowledge and experience of management. We determine whether to record a reserve and, if so, what 
amount based on consideration of the facts and circumstances of each matter as then known to us. Determinations 
regarding whether to record a reserve and, if so, of what amount, reflect management’s assessment regarding what is 
likely to occur; they do not necessarily reflect what management believes should occur. The ultimate resolution of 
any such exposure to us may vary materially from earlier estimates as further facts and circumstances develop or 
become known to us.

Environmental Matters – We are subject to environmental laws and regulations in the jurisdictions in which we do 
or have done business. Factors that could result in changes to the assessment of probability, range of reasonably 
estimated costs and environmental accruals include: modification of planned remedial actions; changes in the 
estimated time required to conduct remedial actions; discovery of more or less extensive (or different) contamination 
than anticipated; information regarding the potential causes and effects of contamination; results of efforts to involve 
other responsible parties; financial capabilities of other responsible parties; changes in laws and regulations, their 
interpretation or application; contractual obligations affecting remediation or responsibilities; and improvements in 
remediation technology. As we expect to be able to recover a portion of environmental remediation liabilities 
through overhead charges on government contracts, such amounts are deferred in prepaid expenses and other current 
assets (current portion) and other non-current assets until charged to contracts. We use judgment to evaluate the 
recoverability of our environmental remediation costs, assessing, among other things, U.S. government regulations, 
our U.S. government contract mix and past practices. Portions of the company’s environmental liabilities we do not 
expect to be recoverable have been expensed. As of December 31, 2023, we expect approximately 90 percent of the 
company’s environmental remediation costs to be recoverable; however, to the extent our judgments on the 
recoverability of our environmental remediation costs change or the unallowable portion of our environmental 

-44-

 
 
 
 
 
 
NORTHROP GRUMMAN CORPORATION

remediation costs otherwise increase, there could be a significant impact on our consolidated financial position, 
annual results of operations and/or cash flows.

Income Tax Matters – The evaluation of tax positions taken in a filed tax return, or planned to be taken in a future 
tax return or claim, requires the use of judgment. We establish reserves for uncertain tax positions when, despite the 
belief that our tax positions are supportable, there remains uncertainty in a tax position taken in our filed tax returns 
or planned to be taken in a future tax return or claim. The company follows a recognition and measurement 
approach, considering the facts, circumstances, and information available at the reporting date. We exercise 
judgment in determining the level of evidence necessary and appropriate to support our assessment using all 
available information. The technical merits of a given tax position are derived from sources of authority in the tax 
law and their applicability to the facts and circumstances of the position. In measuring the tax position, the company 
considers the amounts and probabilities of the outcomes that could be realized upon settlement. When it is more 
likely than not that a tax position will be sustained, we record the largest amount of tax benefit with a greater than 50 
percent likelihood of being realized upon ultimate settlement with a taxing authority. As of December 31, 2023, we 
have approximately $2.0 billion in unrecognized tax benefits. To the extent we prevail in matters for which reserves 
have been established or are required to pay amounts in excess of reserves, there could be a significant impact on 
our consolidated financial position, annual results of operations and/or cash flows.

For further information on litigation, commitments and contingencies, see “Risk Factors” and Note 1, Note 7, Note 
11 and Note 12 to the consolidated financial statements.

Goodwill and Long-Lived Assets
Overview – We allocate the purchase price of acquired businesses to the underlying tangible and intangible assets 
acquired and liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. Such 
fair value assessments require judgments and estimates that can be affected by contract performance and other 
factors over time, which may cause final amounts to differ materially from original estimates. Adjustments to the 
fair value of purchased assets and liabilities after the initial measurement period are recognized in net earnings.

We record property, plant and equipment (PP&E) for capital assets used in operating our business. The cost of 
PP&E utilized in support of our government contracts is generally allowable and allocable cost in accordance with 
applicable FAR and CAS requirements, which limits our risk of impairment on those assets. However, the cost of 
PP&E utilized in support of our commercial business, including approximately $500 million of PP&E used in our 
commercial space business, is not allocable to government contracts and is therefore subject to greater recoverability 
risk.

Impairment Testing – We test for impairment of goodwill annually at each of our reporting units, which comprise 
our operating segments. The results of our annual goodwill impairment tests as of December 31, 2023 and 2022, 
respectively, indicated that the estimated fair value of each reporting unit significantly exceeded its respective 
carrying value. There were no impairment charges recorded in the years ended December 31, 2023, 2022 and 2021.

In addition to performing an annual goodwill impairment test, we may perform an interim impairment test if events 
occur or circumstances change that suggest goodwill in any of our reporting units may be impaired. Such indicators 
may include, but are not limited to, the loss of significant business, significant reductions in federal government 
appropriations or other significant adverse changes in industry or market conditions. During 2023, we determined 
there were no impairment indicators requiring us to perform an interim goodwill impairment test.

When testing goodwill for impairment, we compare the fair values of each of our reporting units to their respective 
carrying values. To determine the fair value of our reporting units, we primarily use the income approach based on 
the cash flows we expect the reporting units to generate in the future, consistent with our operating plans. This 
income valuation method requires management to project sales, operating expenses, working capital, capital 
spending and cash flows for the reporting units over a multi-year period, as well as to determine the weighted-
average cost of capital (WACC) used as a discount rate and terminal value assumptions. The WACC takes into 
account the relative weights of each component of our consolidated capital structure (equity and debt) and represents 
the expected cost of new capital adjusted as appropriate to consider lower risk profiles associated with longer-term 
contracts and barriers to market entry. The terminal value assumptions are applied to the final year of the discounted 
cash flow model. We use industry multiples (including relevant control premiums) of operating earnings to 
corroborate the fair values of our reporting units determined under the market valuation method of the income 
approach.

We test for impairment of our long-lived assets when events or changes in circumstances indicate that the carrying 
amount of these assets may not be recoverable. Our assessment is based on our projection of the undiscounted future 

-45-

 
 
 
 
 
 
NORTHROP GRUMMAN CORPORATION

operating cash flows of the related asset group. If such projections indicate that future undiscounted cash flows are 
not sufficient to recover the carrying amount, we recognize a non-cash impairment charge to reduce the carrying 
amount to fair value. There were no impairment charges recorded in the years ended December 31, 2023, 2022 and 
2021.

Impairment assessment inherently involves management judgments as to assumptions about expected future cash 
flows and the impact of market conditions on those assumptions. Due to the many variables inherent in developing 
the estimates used in our impairment analyses, differences in assumptions may have a material effect on the results 
of those impairment analyses.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

EQUITY RISK

We have been and continue to be exposed to market risk with respect to our portfolio of marketable securities with a 
fair value of $339 million at December 31, 2023. These securities are exposed to market volatilities, changes in price 
and interest rates.

INTEREST RATE RISK

We are exposed to interest rate risk on variable-rate short-term credit facilities for which there were no borrowings 
outstanding at December 31, 2023. At December 31, 2023, we have $13.9 billion of long-term debt, primarily 
consisting of fixed-rate debt, with a fair value of approximately $13.4 billion. The terms of our fixed-rate debt 
obligations do not generally allow investors to demand payment of these obligations prior to maturity. Therefore, we 
do not have significant exposure to interest rate risk for our fixed-rate debt; however, we do have exposure to fair 
value risk if we repurchase or exchange long-term debt prior to maturity. Additionally, if we were to refinance our 
long-term debt, it may be refinanced at higher interest rates.

FOREIGN CURRENCY RISK

In certain circumstances, we are exposed to foreign currency risk. We enter into foreign currency forward contracts 
to manage a portion of the exchange rate risk related to receipts from customers and payments to suppliers 
denominated in foreign currencies. We do not hold or issue derivative financial instruments for trading purposes. At 
December 31, 2023, foreign currency forward contracts with a notional amount of $286 million were outstanding. 
At December 31, 2023, a 10 percent unfavorable foreign exchange rate movement would not have a material impact 
on our consolidated financial position, annual results of operations and/or cash flows. 

INFLATION RISK

The global macroeconomic environment has experienced extraordinary challenges, including the highest rates of 
inflation in 40 years. The company, its subcontractors and other suppliers, have experienced, and continue to 
experience, increased pressures from heightened levels of inflation and the challenges of the current macroeconomic 
environment, which we have not been able to fully mitigate on a number of our fixed-price contracts, in particular 
on the LRIP phase of the B-21 program at Aeronautics Systems. We cannot predict how long these inflationary 
pressures will continue, or how they may change over time, but we expect to see continued impacts on the global 
economy, our customers, our industry and our company. If inflationary pressures continue to persist, they may 
continue to have an adverse impact on our consolidated financial position, results of operations and/or cash flow.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
Northrop Grumman Corporation
Falls Church, Virginia

Opinion on the Financial Statements 

We have audited the accompanying consolidated statements of financial position of Northrop Grumman Corporation 
and subsidiaries (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of 
earnings and comprehensive income, changes in shareholders’ equity, and cash flows for each of the three years in 
the period ended December 31, 2023, and the related notes (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, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the 
period ended December 31, 2023, in conformity with 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, 2023, based on the 
criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission and our report dated January 24, 2024 expressed an unqualified opinion 
on the Company’s internal control over financial reporting.

Basis for Opinion

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

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

Critical Audit Matters

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

Revenue Recognition - Cost and Revenue Estimates for Development Contracts - Refer to Note 1 to the 
financial statements

Critical Audit Matter Description

As more fully described in Note 1 to the financial statements, the Company recognizes substantially all revenue as 
control is transferred to the customer on their long-term contracts over time using the cost-to-cost method (cost 
incurred relative to total cost estimated at completion). Use of the cost-to-cost-method requires the Company to 
make reasonably dependable estimates regarding the revenue and costs associated with the design, manufacture and 
delivery of their products or services. The Company estimates profit on these contracts as the difference between 
total estimated sales and total estimated costs at completion and recognizes that profit as costs are incurred. Cost 

-48-

NORTHROP GRUMMAN CORPORATION

estimates on contracts requiring development work are inherently more uncertain as to future events than production 
contracts, and, as a result, there is typically more variability in those estimates. Certain of these contracts are fixed 
price in nature, which results in greater financial risk associated with unanticipated cost growth. Alternatively, cost-
type contracts may have award or incentive fees that are subject to uncertainty and may be earned over extended 
periods or towards the end of the contract. As a result, the estimation of costs required to complete these contracts 
and the expected revenues that will be earned is complex and requires significant judgment. 

Given the judgment necessary to make reasonably dependable estimates regarding the revenue and costs associated 
with such contracts, auditing these estimates required extensive audit effort due to the complexity of the underlying 
programs and a high degree of auditor judgment when performing audit procedures and evaluating the results of 
those procedures. 

How the Critical Audit Matter Was Addressed in the Audit

Our auditing procedures related to the cost and revenue estimates for these development contracts included the 
following, among others: 

• We tested the effectiveness of controls over the estimates of total costs and revenues on such contracts, 

including development costs and any related award or incentive fee estimates for the relevant performance 
obligations.

• We selected certain long-term contracts for testing and performed the following procedures:

–

–

–

Evaluated whether the recognition of revenue over time on such contracts was appropriate based 
on the terms and conditions of each contract, including whether continuous transfer of control to 
the customer occurred as progress was made toward fulfilling the performance obligation.

Tested management’s identification of distinct performance obligations by evaluating whether the 
underlying goods and services were highly interdependent and interrelated.

Tested management’s determination of the transaction price, including any award or incentive 
fees, based on the consideration expected to be received in accordance with the rights and 
obligations established under the contracts and any contractual modifications. 

–

Evaluated the estimates of total cost and revenue for the performance obligation by:

▪

▪

▪

▪

Conducting inquiries of relevant program teams regarding any challenges related to the 
program.

Comparing costs incurred to date to the costs management estimated to be incurred to 
date.

Evaluating management’s ability to achieve the estimates of cost and revenue by 
performing corroborating inquiries with the Company’s program and business 
management, and testing management’s process used to develop the estimates based on 
their work plans, engineering specifications, program labor, and supplier contracts. This 
includes management’s process to identify macroeconomic impacts to certain programs, 
which could include forecasted cost impacts and assumptions on the ability to recover 
those costs.

Evaluating selected changes to the estimates of costs and obtaining supporting 
documentation on timing and amounts of these changes in estimates.

–

Tested the mathematical accuracy of management’s calculation of revenue recognized during the 
period for the performance obligations. 

Income Taxes - Uncertain Tax Positions - Refer to Notes 1 and 7 to the financial statements

Critical Audit Matter Description

The Company files income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. 
Uncertain tax positions reflect the Company’s expected treatment of tax positions taken in a filed tax return, or 
planned to be taken in a future tax return or claim, which have not been reflected in measuring income tax expense 
or taxes payable for financial reporting purposes. Until these positions are sustained by the taxing authorities or the 
statute of limitations concerning such issues lapses, the Company does not generally recognize the tax benefits 
resulting from such positions and reports the tax effects as a liability for uncertain tax positions in its consolidated 
statements of financial position. The Company has recognized increased uncertain tax positions in recent years 

-49-

 
 
 
 
 
 
NORTHROP GRUMMAN CORPORATION

principally related to state apportionment, the methods of accounting associated with the timing of revenue 
recognition and related costs, and the 2017 Tax Act. Until the matters are resolved, the outcome is inherently 
uncertain. 

Auditing certain assumptions associated with the Company’s uncertain tax positions involved especially challenging 
judgments given the complexity and inherent subjectivity involved in evaluating the potential outcomes of these 
matters.

How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to certain assumptions used in determining uncertain tax positions included the 
following, among others:

• We tested the effectiveness of controls relating to the identification and completeness of, and recognition 

for, uncertain tax positions, including management’s controls over the underlying key assumptions and 
inputs used to derive the estimates.

• With the assistance of our income tax specialists, we selected specific uncertain tax positions for testing and 

performed the following procedures:

–

Inquired of the Company’s tax department, financial reporting department, and other personnel 
directly involved in the development of the estimates. 

– Obtained supporting documentation and evaluated how the Company supported the position, 

including the assumptions and estimates used for measurement, and how the taxing authorities 
have historically challenged the tax position, if applicable.

–

–

Evaluated whether the uncertain tax position met the “more likely than not” recognition threshold.

Evaluated the appropriateness and consistency of the methodologies and assumptions used by 
management when developing these estimates.

• We tested the mathematical accuracy of management’s calculations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations
Northrop Grumman Corporation is a leading global aerospace and defense technology company. We deliver a broad 
range of products, services and solutions to U.S. and international customers, and principally to the U.S. Department 
of Defense and intelligence community. Our broad portfolio is aligned to support national security priorities and our 
solutions equip our customers with capabilities they need to connect, protect and advance humanity.

The company is a leading provider of space systems, military aircraft, missile defense, advanced weapons and long-
range fires capabilities, mission systems, networking and communications, strategic deterrence systems, and 
breakthrough technologies, such as advanced computing, microelectronics and cyber. We are focused on competing 
and winning programs that enable continued growth, performing on our commitments and affordably delivering 
capability our customers need. With the investments we've made in advanced technologies, combined with our 
talented workforce and digital transformation capabilities, Northrop Grumman is well positioned to meet our 
customers' needs today and in the future.

Principles of Consolidation
The consolidated financial statements include the accounts of Northrop Grumman and its subsidiaries and joint 
ventures or other investments for which we consolidate the financial results. Intercompany accounts, transactions 
and profits are eliminated in consolidation. Investments in equity securities and joint ventures where the company 
has significant influence, but not control, are accounted for using the equity method. 

Basis of Presentation
During the first quarter of 2023, we changed the presentation of the components of other comprehensive income 
(loss), net of tax in the consolidated statement of earnings and comprehensive income. Prior period amounts have 
been recast to conform to current period presentation. This change in presentation had no impact on our previously 
reported comprehensive income in total. 

Accounting Estimates
The company’s consolidated financial statements are prepared in conformity with U.S. GAAP. The preparation 
thereof 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 sales and expenses during the reporting period. Estimates have been prepared using the most current and best 
available information; however, actual results could differ materially from those estimates.

Revenue Recognition
The majority of our sales are derived from long-term contracts with the U.S. government for the development or 
production of goods, the provision of services, or a combination of both. The company classifies sales as product or 
service based on the predominant attributes of each performance obligation. 

The company recognizes revenue for each separately identifiable performance obligation in a contract representing a 
promise to transfer a distinct good or service to a customer. In most cases, goods and services provided under the 
company’s contracts are accounted for as single performance obligations due to the complex and integrated nature of 
our products and services. These contracts generally require significant integration of a group of goods and/or 
services to deliver a combined output. In some contracts, the company provides multiple distinct goods or services 
to a customer, most commonly when a contract covers multiple phases of the product life cycle (e.g., development, 
production, sustainment, etc.). In those cases, the company accounts for the distinct contract deliverables as separate 
performance obligations and allocates the transaction price to each performance obligation based on its relative 
standalone selling price, which is generally estimated using cost plus a reasonable margin. Warranties are provided 
on certain contracts, but do not typically provide for services beyond standard assurances and are therefore not 
considered to be separate performance obligations. Assets recognized from the costs to obtain or fulfill a contract are 
not material.

The company recognizes revenue as control is transferred to the customer, either over time or at a point in time. In 
general, our U.S. government contracts contain termination for convenience and/or other clauses that generally 
provide the customer rights to goods produced and/or in-process. Similarly, our non-U.S. government contracts 
generally contain contractual termination clauses or entitle the company to payment for work performed to date for 
goods and services that do not have an alternative use. For most of our contracts, control is effectively transferred 
during the period of performance, so we generally recognize revenue over time using the cost-to-cost method (cost 
incurred relative to total cost estimated at completion). The company believes this represents the most appropriate 

-55-

 
 
 
 
 
 
NORTHROP GRUMMAN CORPORATION

measurement towards satisfaction of its performance obligations. Revenue for contracts in which the control of 
goods produced does not transfer until delivery to the customer is recognized at a point in time (i.e., typically upon 
delivery).

Contracts are often modified for changes in contract specifications or requirements, which may result in scope and/
or price changes. Most of the company’s contract modifications are for goods or services that are not distinct in the 
context of the contract and are therefore accounted for as part of the original performance obligation through a 
cumulative EAC adjustment.

Contract Estimates
Use of the cost-to-cost method requires us to make reasonably dependable estimates regarding the revenue and cost 
associated with the design, manufacture and delivery of our products and services. The company estimates profit on 
these contracts as the difference between total estimated sales and total estimated cost at completion and recognizes 
that profit as costs are incurred. Significant judgment is used to estimate total sales and cost at completion. 

Contract sales may include estimates of variable consideration, including cost or performance incentives (such as 
award and incentive fees), un-priced change orders, REAs and contract claims. Variable consideration is included in 
total estimated sales to the extent it is probable that a significant reversal in the amount of cumulative revenue 
recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. 
We estimate variable consideration as the most likely amount to which we expect to be entitled.

At the request of the National Aeronautics and Space Administration (NASA), Space Systems submitted an 
engineering change proposal (ECP) during the fourth quarter of 2023 for scope increases and other aspects of the 
Habitation and Logistics Outpost (HALO) contract largely stemming from evolving Lunar Gateway architecture and 
mission requirements. The ECP addresses both work performed and work expected to be performed by the company 
resulting from scope changes previously approved by NASA, as well as changes NASA has requested the company 
to propose but has not yet directed the company to perform. The company has begun negotiating with NASA on 
these various changes and other aspects of the HALO contract. The company’s 2023 results include $100 million of 
unfavorable EAC adjustments on the HALO contract and reflect our current best estimate of the outcome of the ECP 
negotiations assuming the terms of the current contract; however, if the outcome is less favorable than what we have 
assumed, it could have an adverse effect on our financial position, results of operations and/or cash flows. 

We  recognize  changes  in  estimated  contract  sales  or  costs  and  the  resulting  changes  in  contract  profit  on  a 
cumulative basis. Cumulative EAC adjustments represent the cumulative effect of the changes on current and prior 
periods; sales and operating margins in future periods are recognized as if the revised estimates had been used since 
contract inception. If it is determined that a loss is expected to result on an individual performance obligation, the 
entire amount of the estimable future loss, including an allocation of G&A costs, is charged against income in the 
period the loss is identified.

B-21 Low-Rate Initial Production Options
In 2015, the U.S. Air Force awarded Northrop Grumman the B-21 contract, which includes a base contract for 
engineering, manufacturing, and design (EMD) and five low-rate initial production (LRIP) options in varying 
quantities. The EMD phase of the program is largely cost type and began at contract award. The LRIP options are 
largely fixed price and are expected to be awarded and executed through approximately the end of the decade. 
During the fourth quarter of 2023, the B-21 program entered flight testing and the company received an award for 
the first LRIP lot.

We previously disclosed it was reasonably possible one or more of the LRIP options could be performed at a loss 
principally due to the company’s estimate of the impact macroeconomic factors may have on our cost to complete 
the LRIP options, as well as ongoing discussions with our suppliers and our customer. During the fourth quarter of 
2023, we again reviewed our estimated profitability on the LRIP phase of the program, and we now believe it is 
probable each of the first five LRIP lots will be performed at a loss. The loss is largely driven by a change in our 
assumptions regarding funding to mitigate the impact of macroeconomic disruptions on the LRIP phase of the 
program and higher projected manufacturing costs that reflect recent supplier negotiations and our experience in 
completing the first aircraft. 

The projected loss across the five LRIP lots, which we recognized during the fourth quarter of 2023, is $1.56 billion. 
The loss comprises a $143 million unfavorable EAC adjustment for the first LRIP lot and a $1.37 billion loss 
contingency accrual and $45 million reduction of inventoried costs for the unexercised LRIP lots. As of December 
31, 2023, $631 million of the loss contingency accrual is included in Other current liabilities and $740 million is 
included in Other non-current liabilities in the consolidated statement of financial position. 

-56-

 
 
 
 
 
 
NORTHROP GRUMMAN CORPORATION

If our estimated cost to complete the LRIP phase of the program changes or our assumptions regarding contract 
performance, quantities, or funding to mitigate the impact of macroeconomic disruptions are resolved more or less 
favorably than what we have estimated, our financial position, results of operations and/or cash flows could be 
materially affected.

EAC adjustments on a single performance obligation can have a significant effect on the company’s financial 
statements. When such adjustments occur, we generally disclose the nature, underlying conditions and financial 
impact of the adjustments. During the fourth quarter of 2023, we recorded a $143 million unfavorable EAC 
adjustment on the first LRIP lot of the B-21 program at Aeronautics Systems as described above. During 2023, we 
recorded $100 million of unfavorable EAC adjustments on the HALO program at Space Systems largely due to cost 
growth stemming from evolving Lunar Gateway architecture and mission requirements combined with 
macroeconomic challenges. During 2022, we recorded $133 million of favorable EAC adjustments on the EMD 
phase of the B-21 program at Aeronautics Systems. During 2021, we recorded $135 million of unfavorable EAC 
adjustments on the F-35 program at Aeronautics Systems. No other such adjustments were significant to the 
financial statements during the years ended December 31, 2023, 2022 and 2021. 

Backlog
Backlog represents the future sales we expect to recognize on firm orders received by the company and is equivalent 
to the company’s remaining performance obligations at the end of each period. It comprises both funded backlog 
(firm orders for which funding is authorized and appropriated) and unfunded backlog. Unexercised contract options 
and IDIQ contracts are not included in backlog until the time an option or IDIQ task order is exercised or awarded.

Company backlog as of December 31, 2023 was $84.2 billion. Of our December 31, 2023 backlog, we expect to 
recognize approximately 40 percent as revenue over the next 12 months and 65 percent as revenue over the next 24 
months, with the remainder to be recognized thereafter. 

Subsequent Event – In January 2024, the company received a termination for convenience in our restricted Space 
business. The company expects to reduce backlog by approximately $2 billion during the first quarter of 2024 
related to the termination.

Contract Assets and Liabilities
For each of the company’s contracts, the timing of revenue recognition, customer billings, and cash collections 
results in a net contract asset or liability at the end of each reporting period. Fixed-price contracts are typically billed 
to the customer either using 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 assets are equivalent to and reflected as Unbilled receivables in the consolidated statements of financial 
position and are primarily related to long-term contracts where revenue recognized under the cost-to-cost method 
exceeds amounts billed to customers. Unbilled receivables are classified as current assets and include amounts that 
may be billed and collected beyond one year due to the long-cycle nature of many of our contracts. Accumulated 
contract costs in unbilled receivables include costs such as direct production costs, factory and engineering 
overhead, production tooling costs, and allowable G&A. Unbilled receivables also include certain estimates of 
variable consideration described above. These contract assets are not considered a significant financing component 
of the company’s contracts as the payment terms are intended to protect the customer in the event the company does 
not perform on its obligations under the contract.

NORTHROP GRUMMAN CORPORATION

Contract liabilities are equivalent to and reflected as Advance payments and billings in excess of costs incurred in 
the consolidated statements of financial position. Certain customers make advance payments prior to the company’s 
satisfaction of its obligations on the contract. These amounts are recorded as contract liabilities until such 
obligations are satisfied, either over time as costs are incurred or at a point in time when deliveries are made. 
Contract liabilities are not a significant financing component as they are generally utilized to pay for contract costs 
within a one-year period or are used to ensure the customer meets contractual requirements.

The change in the balances of the company’s contract assets and liabilities primarily results from timing differences 
between revenue recognition and customer billings and/or payments. Net contract assets as of December 31, 2023 
decreased 37 percent from the prior year, primarily due to decreases in net contracts assets at Space Systems, 
Missions Systems and Aeronautics Systems.

The amount of revenue recognized for the years ended December 31, 2023, 2022 and 2021 that was included in the 
contract liability balance at the beginning of each year was $3.1 billion, $2.4 billion and $2.0 billion, respectively.

Disaggregation of Revenue
See Note 16 for information regarding the company’s sales by customer type, contract type and geographic region 
for each of our segments. We believe those categories best depict how the nature, amount, timing and uncertainty of 
our revenue and cash flows are affected by economic factors.

General and Administrative Expenses
In accordance with applicable FAR and CAS requirements, most general management and corporate expenses 
incurred at the segment and corporate locations are considered allowable and allocable costs to our U.S. government 
contracts. Allowable and allocable G&A costs, including independent research and development (IR&D) and bid 
and proposal (B&P) costs, are allocated on a systematic basis to contracts in progress and are included as a 
component of total estimated contract costs.

Research and Development
Company-sponsored research and development activities primarily include efforts related to government programs. 
Company-sponsored IR&D expenses totaled $1.2 billion, $1.2 billion and $1.1 billion in 2023, 2022 and 2021, 
respectively, which represented 3.0 percent, 3.3 percent and 3.2 percent of total sales, respectively. Customer-funded 
research and development activities are charged directly to the related contracts.

Income Taxes
Provisions for federal and foreign income taxes are calculated on reported earnings before income taxes based on 
current tax law and include the cumulative effect of any changes in tax rates from those used previously in 
determining deferred tax assets and liabilities. Such provisions differ from the amounts currently payable because 
certain items of income and expense are recognized in different periods for financial reporting purposes than for 
income tax purposes. The company recognizes federal and foreign interest accrued related to unrecognized tax 
benefits in income tax expense. Federal tax penalties are also recognized as a component of income tax expense.

In accordance with applicable FAR and CAS requirements, current state and local income and franchise taxes are 
generally considered allowable and allocable costs to our U.S. government contracts and are, therefore, recorded in 
operating costs and expenses. The company generally recognizes changes in deferred state taxes and unrecognized 
state tax benefits in unallocated corporate expenses.

Uncertain tax positions reflect the company’s expected treatment of tax positions taken in a filed tax return, or 
planned to be taken in a future tax return or claim. Until these positions are sustained by the taxing authorities or the 
statute of limitations concerning such issues lapses, the company does not generally recognize the tax benefits 
resulting from such positions and reports the tax effects as a liability for uncertain tax positions in its consolidated 
statements of financial position.

Cash and Cash Equivalents
Cash and cash equivalents are comprised of cash in banks and highly liquid instruments with original maturities of 
three months or less, primarily consisting of bank time deposits and investments in institutional money market 
funds. Cash in bank accounts often exceeds federally insured limits.

Fair Value of Financial Instruments
The company measures the fair value of its financial instruments using observable and unobservable inputs. 
Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal 
market assumptions.

These two types of inputs create the following fair value hierarchy:

Level 1 - Quoted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments 

in markets that are not active; and model-derived valuations whose inputs are observable or whose 
significant value drivers are observable.

Level 3 - Significant inputs to the valuation model are unobservable.

The company holds a portfolio of marketable securities to partially fund non-qualified employee benefit plans. A 
portion of these securities are held in common/collective trust funds and are measured at fair value using NAV per 
share as a practical expedient. Marketable securities accounted for as trading are recorded at fair value on a recurring 
basis and are included in Other non-current assets in the consolidated statements of financial position. Changes in 
unrealized gains and losses on trading securities are included in Other, net in the consolidated statements of earnings 
and comprehensive income. Investments in held-to-maturity instruments with original maturities greater than three 
months are recorded at amortized cost.

Derivative financial instruments are recognized as assets or liabilities in the financial statements and measured at fair 
value on a recurring basis. Changes in the fair value of derivative financial instruments that are designated as fair 
value hedges are recorded in Other, net in the consolidated statements of earnings and comprehensive income, while 
changes in the fair value of derivative financial instruments that are designated as cash flow hedges are recorded as a 
component of other comprehensive income until settlement. For derivative financial instruments not designated as 
hedging instruments, gains or losses resulting from changes in the fair value are reported in Other, net in the 
consolidated statements of earnings and comprehensive income.

The company uses derivative financial instruments to manage its exposure to foreign currency exchange risk related 
to receipts from customers and payments to suppliers denominated in foreign currencies (i.e., foreign currency 
forward contracts). For foreign currency forward contracts, where model-derived valuations are appropriate, the 
company utilizes the income approach to determine the fair value using internal models based on observable market 
inputs such as forward rates, interest rates, our own credit risk and our counterparties’ credit risks.

The company does not use derivative financial instruments for trading or speculative purposes, nor does it use 
leveraged financial instruments. Credit risk related to derivative financial instruments is considered minimal and is 
managed through the use of multiple counterparties with high credit standards and periodic settlements of positions, 
as well as by entering into master netting agreements with most of our counterparties.

Inventoried Costs
Inventoried costs generally comprise costs associated with unsatisfied performance obligations on contracts 
accounted for using point in time revenue recognition, costs incurred in excess of existing contract requirements that 
are probable of recovery and other accrued contract costs that are expected to be recoverable when allocated to 
specific contracts. Product inventory primarily consists of raw materials and is stated at the lower of cost or net 
realizable value, generally using the average cost method.

Inventoried costs include direct production costs, factory and engineering overhead, production tooling costs, and 
allowable G&A. G&A included in Inventoried costs, net was $65 million and $59 million as of December 31, 2023 
and 2022, respectively. Inventoried costs are classified as current assets and include amounts related to contracts 
having production cycles longer than one year due to the long-cycle nature of our business.

Cash Surrender Value of Life Insurance Policies
The company maintains whole life insurance policies on a group of executives, which are recorded at their cash 
surrender value as determined by the insurance carrier. The company also has split-dollar life insurance policies on 
former officers and executives from acquired businesses, which are recorded at the lesser of their cash surrender 
value or premiums paid. These policies are utilized as a partial funding source for deferred compensation and other 

-59-

non-qualified employee retirement plans. As of December 31, 2023 and 2022, the carrying values associated with 
these policies were $399 million and $367 million, respectively, and are recorded in Other non-current assets in the 
consolidated statements of financial position.

Property, Plant and Equipment
Property, plant and equipment (PP&E) are depreciated over the estimated useful lives of individual assets. 
Machinery and other equipment is primarily depreciated using declining-balance methods. The other asset categories 
are generally depreciated using the straight-line method. Depreciation expense is generally an allowable and 
allocable cost in accordance with applicable FAR and CAS requirements and is recorded in the same segment where 
the related assets are held. However, the additional depreciation expense related to the step-up in fair value of PP&E 
acquired through business combinations is recorded in unallocated corporate expense within operating income as 
such depreciation is not allocable to government contracts and not considered part of management’s evaluation of 
segment operating performance. Major classes of PP&E and their useful lives are as follows:

Useful life in years, $ in millions
Land and land improvements
Buildings and improvements
Machinery and other equipment
Capitalized software costs
Leasehold improvements
Property, plant and equipment, at cost
Accumulated depreciation

During the fourth quarter of 2020, the company completed a sale of equipment to a customer on a restricted 
Aeronautics Systems program for $444 million. The company previously intended to use the equipment for internal 
purposes so we recognized the acquisition costs as capital expenditures and included the equipment in PP&E. As we 
regularly sell this type of equipment to customers in the ordinary course of business, we recorded the sale as a 
revenue transaction and included the net book value of the equipment in Operating costs and expenses. Although we 
generally classify proceeds from revenue transactions as cash inflows from operating activities, we recognized the 
proceeds from this transaction as cash inflows from investing activities, consistent with our prior recognition of the 
cost to acquire the equipment as capital expenditures. The company received cash payments of $155 million and $84 
million related to the equipment sale during 2022 and 2021, respectively, and included it in Proceeds from sale of 
equipment to a customer in the consolidated statements of cash flows. The company received no cash payments in 
2023 related to the equipment sale.

During the year ended December 31, 2022, the company acquired $46 million of internal use software through long-
term financing directly with the supplier. The software was recorded in PP&E as a non-cash investing activity and 
the related liability was recorded in long-term debt as a non-cash financing activity. During the years ended 
December 31, 2023 and 2022, the company received lease incentives for landlord funded leasehold improvements of 
$55 million and $96 million, respectively, related to Space Systems real estate leases, which were recorded in PP&E 
and included in non-cash investing activities. 

On December 28, 2022 the company acquired certain leased land in exchange for company-owned land, which had 
been used previously for production-related activities at Space Systems. The exchange was accounted for as a 
nonmonetary transaction, and the acquired land, valued at approximately $155 million, was recorded in PP&E as a 
non-cash investing activity. The transaction resulted in a $96 million gain, which was reflected in operating costs 
and expenses in the consolidated statements of earnings and comprehensive income.

Non-cash investing activities also include capital expenditures incurred but not yet paid of $75 million, $113 million 
and $91 million as of December 31, 2023, 2022 and 2021, respectively.

Sale of Minority Investment
In July 2023, the company sold its minority investment in an Australian business for AUD $235 million (the 
equivalent of $157 million upon settlement). The sale resulted in a pre-tax gain of $97 million, which is reflected in

NORTHROP GRUMMAN CORPORATION

Other, net on the consolidated statements of earnings and comprehensive income for the year ended December 31, 
2023. Proceeds from the sale are included in investing activities on the consolidated statement of cash flows for the 
year ended December 31, 2023.

Goodwill and Other Purchased Intangible Assets
Goodwill and other purchased intangible asset balances are included in the identifiable assets of their assigned 
business segment. However, the company includes the amortization of other purchased intangible assets in 
unallocated corporate expense within operating income as such amortization is not allocable to government contracts 
and not considered part of management’s evaluation of segment operating performance. The company’s customer-
related intangible assets are generally amortized over their respective useful lives based on the pattern in which the 
future economic benefits of the intangible assets are expected to be consumed. Other intangible assets are generally 
amortized on a straight-line basis over their estimated useful lives.

Leases
The company leases certain buildings, land and equipment. At contract inception, we determine whether a contract is 
or contains a lease and whether the lease should be classified as an operating or finance lease. Operating lease 
balances are included in Operating lease right-of-use assets, Other current liabilities, and Operating lease liabilities 
in our consolidated statements of financial position. 

The company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value 
of the future minimum lease payments over the lease term at commencement date. We use our incremental 
borrowing rate based on the information available at commencement date to determine the present value of future 
payments and the appropriate lease classification. Many of our leases include renewal options aligned with our 
contract terms. We define the initial lease term to include renewal options determined to be reasonably certain. We 
do not recognize a right-of-use asset and a lease liability for leases with an initial term of 12 months or less; we 
recognize lease expense for these leases on a straight-line basis over the lease term. We elected the practical 
expedient to not separate lease components from nonlease components and applied that practical expedient to all 
material classes of leased assets. 

Many of the company’s real property lease agreements contain incentives for tenant improvements, rent holidays or 
rent escalation clauses. For tenant improvement incentives received, if the incentive is determined to be a leasehold 
improvement owned by the lessee, the company generally records the incentives as a reduction to the right-of-use 
asset, which reduces rent expense over the lease term. For rent holidays and rent escalation clauses during the lease 
term, the company records rental expense on a straight-line basis over the term of the lease. For these lease 
incentives, the company uses the date of initial possession as the commencement date, which is generally when the 
company is given the right of access to the space and begins to make improvements in preparation for intended use.

Finance leases are not material to our consolidated financial statements and the company is not a lessor in any 
material arrangements. We do not have any material restrictions or covenants in our lease agreements, sale-
leaseback transactions, land easements or residual value guarantees.

Litigation, Commitments and Contingencies
We accrue for litigation, commitments and contingencies when management, after considering the facts and 
circumstances of each matter as then known to management, has determined it is probable a liability will be found to 
have been incurred and the amount of the loss can be reasonably estimated. When only a range of amounts is 
reasonably estimable and no amount within the range is more likely than another, the low end of the range is 
recorded. Legal fees are generally expensed as incurred. Due to the inherent uncertainties surrounding gain 
contingencies, we generally do not recognize potential gains until realized.

Environmental Costs
We accrue for environmental liabilities when management determines that, based on the facts and circumstances 
known to the company, it is probable the company will incur costs to address environmental impacts and the costs 
are reasonably estimable. When only a range of amounts is reasonably estimable and no amount within the range is 
more likely than another, we record the low end of the range. The company typically projects environmental costs 
for up to 30 years, records environmental liabilities on an undiscounted basis, and excludes asset retirement 
obligations and certain legal costs. At sites involving multiple parties, we accrue environmental liabilities based 
upon our expected share of liability, taking into account the financial viability of other liable parties. 

Retirement Benefits
The company sponsors various defined benefit pension plans and defined contribution retirement plans covering 
substantially all of its employees. In most cases, our defined contribution plans provide for a company match of 

-61-

 
 
 
 
 
 
NORTHROP GRUMMAN CORPORATION

employee contributions. The company also provides postretirement benefits other than pensions to eligible retirees 
and qualifying dependents, consisting principally of health care and life insurance benefits.

The liabilities, unamortized prior service credits and annual income or expense of the company’s defined benefit 
pension and OPB plans are determined using methodologies that involve several actuarial assumptions. 

Because U.S. government regulations provide for the costs of pension and OPB plans to be charged to our contracts 
in accordance with applicable FAR and CAS requirements, we calculate retiree benefit plan costs under both FAS 
and CAS methods. While both FAS and CAS recognize a normal service cost component in measuring periodic 
pension cost, there are differences in the way the components of annual pension costs are calculated under each 
method. Measuring plan obligations under FAS and CAS includes different assumptions and models, such as in 
estimating returns on plan assets, calculating interest expense and the periods over which gains/losses related to 
pension assets and actuarial changes are recognized. As a result, annual retiree benefit plan expense amounts for 
FAS are different from the amounts for CAS in any given reporting period even though the ultimate cost of 
providing benefits over the life of the plans is the same under either method. CAS retiree benefit plan costs are 
charged to contracts and are included in segment operating income, and the difference between the service cost 
component of FAS expense and total CAS expense (the “FAS/CAS operating adjustment”) is recorded in operating 
income at the consolidated company level. Not all net periodic pension expense is recognized in net earnings in the 
year incurred because it is allocated as production costs and a portion remains in inventory at the end of any given 
reporting period. 

Actuarial gains and losses are immediately recognized in net periodic benefit cost for FAS through MTM (expense) 
benefit upon annual remeasurement in the fourth quarter, or on an interim basis as triggering events warrant 
remeasurement. Prior service credits are recognized as a component of Accumulated other comprehensive loss and 
amortized into earnings in future periods.

Stock Compensation
The company’s stock compensation plans are classified as equity plans. Compensation expense for stock awards is 
measured at the grant date based on the fair value of the award and is recognized over the vesting period (generally 
three years), net of estimated forfeitures. The company issues stock awards in the form of restricted performance 
stock rights and restricted stock rights. The fair value of stock awards and performance stock awards is determined 
based on the closing market price of the company’s common stock on the grant date. The fair value of market-based 
stock awards is determined at the grant date using a Monte Carlo simulation model. For purposes of measuring 
compensation expense for performance awards, the number of shares ultimately expected to vest is estimated at each 
reporting date based on management’s expectations regarding the relevant performance criteria. At each reporting 
date, the number of shares used to calculate compensation expense and diluted earnings per share is adjusted to 
reflect the number ultimately expected to vest.

Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive loss, net of tax, are as follows:

$ in millions
Cumulative translation adjustment
Other, net
Total accumulated other comprehensive loss

For all periods presented, the company had no material related party transactions.

Accounting Standards Updates
On November 27, 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 
(ASU) No. 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. Among 
other new disclosure requirements, ASU 2023-07 requires companies to disclose significant segment expenses that 
are regularly provided to the chief operating decision maker. ASU 2023-07 will be effective for annual periods 
beginning on January 1, 2024 and interim periods beginning on January 1, 2025. ASU 2023-07 must be applied 
retrospectively to all prior periods presented in the financial statements. We are evaluating the disclosure impact of 
ASU 2023-07; however, the standard will not have an impact on the company’s consolidated financial position, 
results of operations and/ or cash flows.

On December 14, 2023, the FASB issued ASU No. 2023-09 Income Taxes (Topic 740): Improvements to Income 
Tax Disclosures. ASU 2023-09 requires companies to disclose, on an annual basis, specific categories in the 
effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative 
threshold. In addition, ASU 2023-09 requires companies to disclose additional information about income taxes paid. 
ASU 2023-09 will be effective for annual periods beginning January 1, 2025 and will be applied on a prospective 
basis with the option to apply the standard retrospectively. We are evaluating the disclosure impact of ASU 2023-09; 
however, the standard will not have an impact on the company’s consolidated financial position, results of 
operations and/or cash flows.

Other accounting standards updates adopted and/or issued, but not effective until after December 31, 2023, are not 
expected to have a material effect on the company’s consolidated financial position, annual results of operations 
and/or cash flows.

2.   DISPOSITIONS

Disposition of IT and Mission Support Services Business
Effective January 30, 2021, we completed the IT services divestiture for $3.4 billion in cash and recorded a pre-tax 
gain of $2.0 billion. The IT and mission support services business was comprised of the majority of the former 
Information Solutions and Services (IS&S) division of Defense Systems (excluding the Vinnell Arabia business); 
select cyber, intelligence and missions support programs, which were part of the former Cyber and Intelligence 
Mission Solutions (CIMS) division of Mission Systems; and the former Space Technical Services business unit of 
Space Systems. Operating results include sales and operating income for the IT and mission support services 
business prior to the Divestiture date; therefore, no sales and operating income were recognized for this business 
during the years ended December 31, 2023 and 2022. The company recorded sales of $162 million and pre-tax profit 
of $20 million for the IT and mission support services business during the year ended December 31, 2021.

3.   EARNINGS PER SHARE, SHARE REPURCHASES AND DIVIDENDS ON COMMON STOCK

Basic Earnings Per Share
We calculate basic earnings per share by dividing net earnings by the weighted-average number of shares of 
common stock outstanding during each period.

Diluted Earnings Per Share
Diluted earnings per share include the dilutive effect of awards granted to employees under stock-based 
compensation plans. The dilutive effect of these securities totaled 0.5 million, 0.7 million and 0.6 million shares for 
the years ended December 31, 2023, 2022 and 2021, respectively.

Share Repurchases
Share Repurchase Programs
On December 4, 2018, the company’s board of directors authorized a share repurchase program of up to $3.0 billion 
in share repurchases of the company’s common stock (the “2018 Repurchase Program”). Repurchases under the 
2018 Repurchase Program commenced in March 2020 and were completed in October 2021.

On January 25, 2021, the company’s board of directors authorized a new share repurchase program of up to an 
additional $3.0 billion in share repurchases of the company’s common stock (the “2021 Repurchase Program”). 
Repurchases under the 2021 Repurchase Program commenced in October 2021 and were completed in April 2023.

On January 24, 2022, the company’s board of directors authorized a new share repurchase program of up to an 
additional $2.0 billion in share repurchases of the company’s common stock (the “2022 Repurchase Program”). 
Repurchases under the 2022 Repurchase Program commenced in April 2023 upon completion of the 2021 
Repurchase Program. As of December 31, 2023, repurchases under the 2022 Repurchase Program totaled 
$0.9 billion; $1.1 billion remained under this share repurchase authorization. By its terms, the 2022 Repurchase 
Program will expire when we have used all authorized funds for repurchases.

On December 6, 2023, the company’s board of directors authorized a new share repurchase program of up to an 
additional $2.5 billion in share repurchases of the company’s common stock (the “2023 Repurchase Program”). 
Repurchases under the 2023 Repurchase Program will commence upon completion of the 2022 Repurchase Program 
and will expire when we have used all authorized funds for repurchases. As of December 31, 2023, there have been 
no repurchases under the 2023 Repurchase Program and the company’s total outstanding share repurchase 
authorization was $3.6 billion.

Accelerated Share Repurchase Agreements
During the first quarter of 2021, the company entered into an accelerated share repurchase (ASR) agreement with 
Goldman Sachs & Co. LLC (Goldman Sachs) to repurchase $2.0 billion of the company’s common stock as part of 
the 2018 Repurchase Program. Under the agreement, we made a payment of $2.0 billion to Goldman Sachs and 
received an initial delivery of 5.9 million shares valued at $1.7 billion that were immediately canceled by the 
company. The remaining balance of $300 million was settled on June 1, 2021 with a final delivery of 0.2 million 
shares from Goldman Sachs. The final average purchase price was $327.29 per share.

During the fourth quarter of 2021, the company entered into an ASR agreement with Goldman Sachs to repurchase 
$500 million of the company’s common stock as part of the 2021 Repurchase Program. Under the agreement, we 
made a payment of $500 million to Goldman Sachs and received an initial delivery of 1.2 million shares valued at 
$425 million that were immediately canceled by the company. The remaining balance of $75 million was settled on 
February 1, 2022 with a final delivery of 0.1 million shares from Goldman Sachs. The final average purchase price 
was $374.79 per share.

During the first quarter of 2023, the company entered into an ASR agreement with Bank of America, N.A. (Bank of 
America) to repurchase $500 million of the company’s common stock as part of the 2021 and 2022 Repurchase 
Programs. Under the agreement, we made a payment of $500 million to Bank of America and received an initial 
delivery of 0.9 million shares valued at $400 million that were immediately canceled by the company. The 
remaining balance of $100 million was settled on April 27, 2023 with a final delivery of 0.2 million shares from 
Bank of America. The final average purchase price was $458.28 per share.

Share repurchases take place from time to time, subject to market and regulatory conditions and management’s 
discretion, in the open market or in privately negotiated transactions. The company retires its common stock upon 
repurchase and, in the periods presented, has not made any purchases of common stock other than in connection 
with these publicly announced repurchase programs.

6.   INVENTORIED COSTS, NET

Inventoried costs are principally associated with contracts where the U.S. government is the primary customer, 
therefore the company does not believe it has significant exposure to recoverability risk related to these amounts. 
Inventoried costs associated with our commercial businesses, while less significant in total, are subject to a greater 
level of recoverability risk. The company recorded write-downs of commercial business inventory at Space Systems 
for which its cost exceeded net realizable value of $43 million and $45 million during the years ended December 31, 
2023 and 2022, respectively. As discussed in Note 1, the company recognized a $45 million reduction of inventoried

The 2023 ETR decreased to 12.4 percent from 16.1 percent in 2022 primarily due to lower earnings before income 
taxes as a result of the B-21 charge and MTM expense, which collectively reduced the 2023 ETR by 3.8 percentage 
points. The 2022 MTM benefit increased the 2022 ETR by 1.2 percentage points.

The 2022 ETR decreased to 16.1 percent from 21.6 percent in 2021 primarily due to an $86 million benefit resulting 
from the resolution of the IRS examination of certain legacy OATK tax returns, as well as additional federal income 
taxes in the prior year resulting from the IT services divestiture. The company’s 2022 MTM benefit increased the 
2022 ETR by 1.2 percentage points; however, the MTM benefit in 2021 did not significantly impact the 2021 ETR.

Income tax payments, net of refunds received, were $1.2 billion, $1.5 billion and $1.3 billion for the years ended 
December 31, 2023, 2022 and 2021, respectively. Taxes receivable, which are included in Prepaid expenses and 
other current assets in the consolidated statements of financial position, were $1.5 billion and $850 million as of 
December 31, 2023 and 2022, respectively.

Uncertain Tax Positions
We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. The 
Northrop Grumman 2018-2020 federal tax returns are currently under Internal Revenue Service (IRS) examination. 
During the second quarter of 2023, the company entered into an agreed Revenue Agent’s Report (“RAR”) for 
certain matters related to the company’s 2014-2017 federal income tax returns, resulting in a $90 million reduction 
to our unrecognized tax benefits and an immaterial impact to income tax expense. The matters not addressed by the 
agreed RAR related to the company’s 2014-2017 federal income tax returns and refund claims related to its 
2007-2016 federal tax returns are currently under review by the IRS Appeals Office.

In the second quarter of 2023, the California Franchise Tax Board approved a resolution of the state examination 
primarily related to California state apportionment in the company’s 2007 to 2016 tax years, resulting in a 
$95 million reduction to our unrecognized tax benefits and an $11 million reduction to unallocated corporate 
expense.

Tax returns for open tax years related to state and foreign jurisdictions remain subject to examination. As state 
income taxes are generally considered allowable and allocable costs, any individual or aggregate state examination 
impacts are not expected to have a material impact on our financial results. Amounts currently subject to 
examination related to foreign jurisdictions are not material.

Our 2023 increase in unrecognized tax benefits was primarily related to our methods of accounting associated with 
the timing of revenue recognition and related costs and the 2017 Tax Cuts and Jobs Act, which includes related final 
revenue recognition regulations issued in December 2020 under IRC Section 451(b) and procedural guidance issued 
in August 2021. As of December 31, 2023, we have approximately $2.0 billion in unrecognized tax benefits, 
including $843 million related to our position on IRC Section 451(b). If these matters, including our position on IRC 
Section 451(b), are unfavorably resolved, there could be a material impact on our future cash flows. It is reasonably 
possible that within the next 12 months our unrecognized tax benefits related to these matters may increase by 
approximately $120 million. 

Our current unrecognized tax benefits, which are included in Other current liabilities in the consolidated statements 
of financial position, were $964 million and $728 million as of December 31, 2023 and 2022, respectively, with the 
remainder of our unrecognized tax benefits included within Other non-current liabilities. These liabilities include 
$305 million and $216 million of accrued interest and penalties as of December 31, 2023 and 2022, respectively. If 
the income tax benefits from these tax positions are ultimately realized, $848 million of federal and foreign tax 
benefits would reduce the company’s ETR.

Net interest expense within the company’s federal, foreign and state income tax provisions was $62 million, 
$29 million, and $25 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Realization of deferred tax assets is primarily dependent on generating sufficient taxable income in future periods. 
The company believes it is more-likely-than-not our net deferred tax assets will be realized.

At December 31, 2023, the company has available tax credits and unused net operating losses of $615 million and 
$358 million, respectively, that may be applied against future taxable income. The majority of tax credits and net 
operating losses expire in 2024 through 2046, however, some may be carried forward indefinitely. Due to the 
uncertainty of the realization of the tax credits and net operating losses, the company has recorded valuation 
allowances of $344 million and $46 million, respectively, as of December 31, 2023.

Undistributed Foreign Earnings 
As of December 31, 2023, the company has accumulated undistributed earnings generated by our foreign 
subsidiaries and most have been taxed in the U.S. We intend to indefinitely reinvest these earnings, as well as future 
earnings from our foreign subsidiaries to fund our international operations. In addition, we expect future U.S. cash 
generation will be sufficient to meet future U.S. cash needs.

The notional value of the company’s foreign currency forward contracts at December 31, 2023 and 2022 was $286 
million and $221 million, respectively. The portion of notional value designated as a cash flow hedge at December 
31, 2023 and 2022 was $162 million and $87 million, respectively. 

The derivative fair values and related unrealized gains/losses at December 31, 2023 and 2022 were not material.

There were no transfers of financial instruments into or out of Level 3 of the fair value hierarchy during the years 
ended December 31, 2023 and 2022.

The carrying value of cash and cash equivalents and commercial paper approximates fair value.

10.   DEBT

Commercial Paper
The company maintains a commercial paper program that serves as a source of short-term financing with capacity to 
issue unsecured commercial paper notes up to $2.5 billion. There were no commercial paper borrowings outstanding 
at December 31, 2023 and December 31, 2022, respectively.

Credit Facility
The company maintains a five-year senior unsecured credit facility in an aggregate principal amount of $2.5 billion 
(the “2022 Credit Agreement”) that matures in August 2027. The revolving credit facility established under the 2022 
Credit Agreement is intended to support the company’s commercial paper program and other general corporate 
purposes. Commercial paper borrowings reduce the amount available for borrowing under the 2022 Credit 
Agreement. At December 31, 2023, there were no borrowings outstanding under this facility. 

The 2022 Credit Agreement contains generally customary terms and conditions, including covenants restricting the 
company’s ability to sell all or substantially all of its assets, merge or consolidate with another entity or undertake 
other fundamental changes and incur liens. The company also cannot permit the ratio of its debt to capitalization (as 
set forth in the credit agreement) to exceed 65 percent. At December 31, 2023, the company was in compliance with 
all covenants under its credit agreement.

Unsecured Senior Notes 
Issuance of Senior Notes
In February 2023, the company issued $2.0 billion of unsecured senior notes for general corporate purposes, 
including debt repayment, share repurchases, and working capital, as follows:

•

•

$1.0 billion of 4.70% senior notes due 2033 (the “2033 Notes”) and

$1.0 billion of 4.95% senior notes due 2053 (the “2053 Notes”).

We refer to the 2033 Notes and the 2053 Notes, together, as the “notes.” Interest on the notes is payable semi-
annually in arrears. The notes are generally subject to redemption, in whole or in part, at the company’s discretion at 
any time, or from time to time, prior to maturity at a redemption price equal to the greater of 100% of the principal 
amount of the notes to be redeemed or an applicable “make-whole” amount, plus accrued and unpaid interest.

Repayments of Senior Notes
In August 2023, the company repaid $1.05 billion of 3.25 percent unsecured senior notes upon maturity.

In March 2021, the company repaid $700 million of 3.50 percent unsecured notes upon maturity.

In March 2021, the company redeemed $1.5 billion of 2.55 percent unsecured notes due October 2022. The 
company recorded a pre-tax charge of $54 million principally related to the premium paid on the redemption, which 
was recorded in Other, net in the consolidated statements of earnings and comprehensive income.

Debt Exchange
On September 2, 2021, the company completed an exchange offer to eligible holders of the outstanding notes of our 
direct wholly owned subsidiary, Northrop Grumman Systems Corporation (“NGSC”), maturing through 2036. An 
aggregate principal amount of $422 million of the NGSC notes was exchanged for $422 million of unregistered 
Northrop Grumman Corporation notes (the “Unregistered Notes”) with the same interest rates and maturity dates as 
the NGSC notes exchanged.

On June 15, 2022, the company completed a registered exchange offer pursuant to which the company exchanged an 
aggregate principal amount of $414 million of the Unregistered Notes for $414 million of new notes registered 
under the Securities Act of 1933, as amended, (the “Registered Notes”) with the same interest rates and maturity 
dates as the Unregistered Notes.

(1) The current portion of long-term debt is recorded in Other current liabilities in the consolidated statements of financial 
position.

The estimated fair value of long-term debt was $13.4 billion and $12.1 billion as of December 31, 2023 and 2022, 
respectively. We calculated the fair value of long-term debt using Level 2 inputs, based on interest rates available for 
debt with terms and maturities similar to the company’s existing debt arrangements. 

Indentures underlying long-term debt issued by the company or its subsidiaries contain various restrictions with 
respect to the issuer, including one or more restrictions relating to limitations on liens, sale-leaseback arrangements 
and funded debt of subsidiaries. The majority of these fixed rate notes and debentures are subject to redemption at 
the company’s discretion at any time prior to maturity in whole or in part at the principal amount plus any make-
whole premium and accrued and unpaid interest. Interest on these fixed rate notes and debentures are payable semi-
annually in arrears.

Total interest payments, net of interest received and capitalized, were $437 million, $474 million and $570 million 
for the years ended December 31, 2023, 2022 and 2021, respectively. The company capitalized interest expense of 
$95 million, $53 million and $17 million during the years ended December 31, 2023, 2022 and 2021, respectively.

For over 25 years, the company has worked closely with the United States Navy, the United States Environmental 
Protection Agency, the New York State Department of Environmental Conservation, the New York State 
Department of Health and other federal, state and local governmental authorities, to address environmental 
conditions allegedly resulting from historic operations at the former United States Navy and Grumman facilities in 
Bethpage, New York. We have incurred, and expect to continue to incur, as included in Note 12, substantial 
remediation costs related to these Bethpage environmental conditions. It is also possible that applicable remediation 
standards and other requirements to which we are subject may continue to change, and that our costs may increase 
materially. In 2022, we resolved several disputes and regulatory proceedings concerning the scope and allocation of 
remediation responsibilities and costs related to this site. The company continues to be involved in related disputes, 
none of which are material individually or in the aggregate. We are also a party to various individual lawsuits and a 
putative class action in the Eastern District of New York alleging personal injury and property damage related to the 
legacy Bethpage environmental conditions. The court has stayed the filed individual lawsuits, pending its decision 
on class certification. We are also a party, and may become a party, to other lawsuits brought by or against insurance 
carriers, and by other individual plaintiffs and/or putative classes, as well as other parties. We cannot at this time 
predict or reasonably estimate the potential cumulative outcomes or ranges of possible liability of these Bethpage 
lawsuits. 

The company received from the U.S. Department of Justice (DOJ) a criminal subpoena on December 9, 2022, and a 
civil investigative demand on February 2, 2023, both seeking information regarding financial and cost accounting 
and controls that appears focused on the interest rate assumptions the company used to determine our CAS pension 
expense, which we discuss in Note 12 below. The company is engaging with the government and responding to the 
requests. We cannot at this point predict the outcome of these matters. 

The company is a party to various other investigations, lawsuits, arbitration, claims, enforcement actions and other 
legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. 
The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. However, based 
on information available to the company to date, the company does not believe that the outcome of any of these 
other matters pending against the company is likely to have a material adverse effect on the company’s consolidated 
financial position as of December 31, 2023, or its annual results of operations and/or cash flows.

12.   COMMITMENTS AND CONTINGENCIES

U.S. Government Cost Claims and Contingencies
From time to time, the company is advised of claims by the U.S. government concerning certain potential disallowed 
costs, plus, at times, penalties and interest. When such findings are presented, the company and U.S. government 
representatives engage in discussions to enable the company to evaluate the merits of these claims, as well as to 
assess the amounts being claimed. Where appropriate, provisions are made to reflect the company’s estimated 
exposure for such potential disallowed costs. Such provisions are reviewed periodically using the most recent 
information available. The company believes it has adequately reserved for disputed amounts that are probable and 
reasonably estimable, and that the outcome of any such matters would not have a material adverse effect on its 
consolidated financial position as of December 31, 2023, or its annual results of operations and/or cash flows.

NORTHROP GRUMMAN CORPORATION

In 2019, the Defense Contract Management Agency (DCMA) raised questions about an interest rate assumption 
used by the company to determine our CAS pension expense. On June 1, 2020, DCMA provided written notice that 
the assumptions the company used during the period 2013-2019 were potentially noncompliant with CAS. We 
submitted a formal response on July 31, 2020, which we believed demonstrates the appropriateness of the 
assumptions used. On November 24, 2020, DCMA replied to the company’s response, disagreeing with our position 
and requesting additional input, which we provided on February 22, 2021. We have continued to exchange 
correspondence and engage with DCMA on this matter, including responding to requests for and providing 
additional information. As noted in Note 11 above, the company received from the DOJ a criminal subpoena on 
December 9, 2022, and a CID on February 2, 2023, both seeking information that appears related to the interest rate 
assumptions at issue in our discussions with DCMA. The company is engaging with the government and responding 
to the requests. We cannot at this point predict the outcome of these matters. As previously described, the sensitivity 
to changes in interest rate assumptions makes it reasonably possible the outcome of the DCMA matter could have a 
material adverse effect on our financial position, results of operations and/or cash flows, although we are not 
currently able to estimate a range of any potential loss.

Environmental Matters
The table below summarizes the amount accrued for environmental remediation costs, management’s estimate of the 
amount of reasonably possible future costs in excess of accrued costs and the deferred costs expected to be 
recoverable through overhead charges on U.S. government contracts as of December 31, 2023 and 2022:

(1) As of December 31, 2023, $223 million is recorded in Other current liabilities and $361 million is recorded in Other non-

current liabilities. 

(2) Estimated remediation costs are not discounted to present value. The reasonably possible future costs in excess of accrued 
costs do not take into consideration amounts expected to be recoverable through overhead charges on U.S. government 
contracts.

(3) As of December 31, 2023, $206 million is deferred in Prepaid expenses and other current assets and $312 million is deferred in 

Other non-current assets. These amounts are evaluated for recoverability on a routine basis.

Although management cannot predict whether (i) new information gained as our environmental remediation projects 
progress, (ii) changes in remediation standards or other requirements to which we are subject, or (iii) other changes 
in facts and circumstances will materially affect the estimated liability accrued, we do not anticipate that future 
remediation expenditures associated with our currently identified projects will have a material adverse effect on the 
company’s consolidated financial position as of December 31, 2023, or its annual results of operations and/or cash 
flows.

Financial Arrangements
In the ordinary course of business, the company uses standby letters of credit and guarantees issued by commercial 
banks and surety bonds issued principally by insurance companies to guarantee the performance on certain 
obligations. At December 31, 2023, there were $411 million of stand-by letters of credit and guarantees and $263 
million of surety bonds outstanding.

Indemnifications
The company has provided indemnifications for certain environmental, income tax and other potential liabilities in 
connection with certain of its divestitures. The settlement of these liabilities is not expected to have a material 
adverse effect on the company’s consolidated financial position as of December 31, 2023, or its annual results of 
operations and/or cash flows.

13.   RETIREMENT BENEFITS

Plan Descriptions
U.S. Defined Benefit Pension Plans – The company sponsors several defined benefit pension plans in the U.S. 
Pension benefits for most participants are based on years of service, age and compensation. It is our policy to fund at

NORTHROP GRUMMAN CORPORATION

least the minimum amount required for qualified plans, using actuarial cost methods and assumptions acceptable 
under U.S. government regulations, by making payments into benefit trusts separate from the company.

U.S. Defined Contribution Plans – The company also sponsors defined contribution plans covering the majority of 
its employees, including certain employees covered under collective bargaining agreements. Company contributions 
vary depending on date of hire, with a majority of employees being eligible for employer matching of employee 
contributions. Based on date of hire, certain employees are eligible to receive a company non-elective contribution 
or an enhanced matching contribution in lieu of a defined benefit pension plan benefit. The company’s contributions 
to these defined contribution plans for the years ended December 31, 2023, 2022 and 2021, were $634 million, $558 
million and $588 million, respectively.

Non-U.S. Benefit Plans – The company sponsors several benefit plans for non-U.S. employees. These plans are 
designed to provide benefits appropriate to local practice and in accordance with local regulations. Some of these 
plans are funded using benefit trusts separate from the company.

Medical and Life Benefits – The company funds a portion of the costs for certain health care and life insurance 
benefits for a substantial number of its active and retired employees. In addition to a company and employee cost-
sharing feature, the health plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-
pocket limits, conformance to a schedule of reasonable fees, the use of managed care providers and coordination of 
benefits with other plans. The plans also provide for a Medicare carve-out. The company reserves the right to amend 
or terminate the plans at any time. 

Certain covered employees and dependents are eligible to participate in plans upon retirement if they meet specified 
age and years of service requirements. The company provides subsidies to reimburse certain retirees for a portion of 
the cost of individual Medicare-supplemental coverage purchased directly by the retiree through a private insurance 
exchange. The company has capped the amount of its contributions for substantially all of its remaining 
postretirement medical and life benefit plans. In addition, after January 1, 2005 (or earlier at some businesses), 
newly hired employees are not eligible for subsidized postretirement medical and life benefits.

Summary Plan Results
The cost to the company of its retirement benefit plans is shown in the following table:

The increase in the fair value of our plan assets for the year ended December 31, 2023 was principally driven by net 
plan asset returns of 11.1 percent, partially offset by $2.1 billion of benefit payments. The increase in our projected 
benefit obligation for the year ended December 31, 2023, was primarily driven by $1.6 billion of interest cost and a 
39 basis point decrease in the discount rate from year end 2022, partially offset by $2.1 billion of benefit payments.

Plan Assets and Investment Policy
Plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and 
investment return over the long term. Liability studies are conducted on a regular basis to provide guidance in 
setting investment goals with an objective to balance risk. Risk targets are established and monitored against 
acceptable ranges.

Our investment policies and procedures are designed to ensure the plans’ investments are in compliance with 
ERISA. Guidelines are established defining permitted investments within each asset class. Derivatives are used for 
transitioning assets, asset class rebalancing, managing currency risk and for management of fixed-income and 
alternative investments.

international equities consist primarily of common stocks and institutional common trust funds. Investments in 
certain equity securities, which include domestic and international securities and registered investment companies, 
and exchange-traded funds with fixed income strategies are valued at the last reported sales or quoted price on the 
last business day of the reporting period. Fair values for certain fixed-income securities, which are not exchange-
traded, are valued using third-party pricing services.

Other assets include derivative assets with a fair value of $172 million and $71 million, derivative liabilities with a 
fair value of $101 million and $117 million, and net notional amounts of $4.9 billion and $3.2 billion, as of 
December 31, 2023 and 2022, respectively. Derivative instruments may include exchange traded futures contracts, 
interest rate swaps, options on futures and swaps, currency contracts, total return swaps and credit default swaps. 
Notional amounts do not quantify risk or represent assets or liabilities of the pension and VEBA trusts, but are used 
in the calculation of cash settlement under the contracts. The volume of derivative activity is commensurate with the 
amounts disclosed at year-end. Certain derivative financial instruments within the pension trust are subject to master 
netting agreements with certain counterparties.

Investments in certain equity and fixed-income funds, which include common/collective trust funds, and alternative 
investments, including hedge funds, opportunistic investments, private equity funds and real estate funds, are valued 
based on the NAV derived by the investment managers, as a practical expedient, and are described further below. 

U.S. and International equities: Generally, redemption periods are daily, monthly or quarterly with a notice 
requirement less than 90 days. As of December 31, 2023 and 2022, there were no unfunded commitments. 

Fixed-income funds: Generally, redemption periods are daily, monthly or quarterly with a notice requirement of two 
days. As of December 31, 2023 and 2022 there were no unfunded commitments.

Hedge funds: Consist of closed-end funds with a 5-10 year life as well as funds that allow redemption requests 
subject to the liquidity limitations of the underlying investments. As of December 31, 2023 and 2022, unfunded 
commitments were $6 million.

Opportunistic investments: Primarily held in partnerships with a 5-10 year life. As of December 31, 2023 and 2022, 
unfunded commitments were $1.6 billion and $1.5 billion, respectively.

Private equity funds: The term of each fund is typically 10 or more years and the fund’s investors do not have an 
option to redeem their interest in the fund. As of December 31, 2023 and 2022, unfunded commitments were $1.9 
billion and $2.0 billion, respectively.

Real estate funds: Consist primarily of open-end funds that generally allow investors to redeem their interests in the 
funds. Certain closed-end real estate funds have terms of 10 or more years. As of December 31, 2023 and 2022, 
unfunded commitments were $28 million and $44 million, respectively.

For the years ended December 31, 2023 and 2022, the defined benefit pension and VEBA trusts did not hold any 
Northrop Grumman common stock.

14.   STOCK COMPENSATION PLANS AND OTHER COMPENSATION ARRANGEMENTS

Stock Compensation Plans
At December 31, 2023, the company had stock-based compensation awards outstanding under the following 
shareholder-approved plans: the 2011 Long-Term Incentive Stock Plan (2011 Plan), applicable to employees and 
non-employee directors, and the 1993 Stock Plan for Non-Employee Directors (1993 SPND).

Employee Plans – In May 2015, the company’s shareholders approved amendments to the 2011 Plan. These 
amendments provided that shares issued under the plan would be counted against the aggregate share limit on a one-
for-one basis. As amended, 5.1 million shares plus 2.4 million of newly authorized shares were available for 
issuance under the 2011 Plan; as of December 31, 2023, 4.4 million shares remain available for issuance. 

The 2011 Plan provides for the following equity awards: stock options, stock appreciation rights (SARs) and stock 
awards. Under the 2011 Plan, no SARs have been granted and there are no outstanding stock options. Stock awards 
include restricted performance stock rights (RPSR) and restricted stock rights (RSR). RPSRs generally vest and are 
paid following the completion of a three-year performance period, based primarily on achievement of certain 
performance metrics determined by the Board. RSRs generally vest 100% after three years. Each includes dividend 
equivalents, which are paid concurrently with the RPSR or RSR. The terms of equity awards granted under the 2011 
Plan provide for accelerated vesting, and in some instances forfeiture, of all or a portion of an award upon 
termination of employment.

Non-Employee Director Plans – Awards to non-employee directors are made pursuant to the Northrop Grumman 
Corporation Equity Grant Program for Non-Employee Directors under the 2011 Plan (the Director Program), which 
was amended and restated effective January 1, 2016. Under the amended Director Program, each non-employee 
director is awarded an annual equity grant in the form of Automatic Stock Units, which vest on the one-year 
anniversary of the grant date. Directors may elect to have all or any portion of their Automatic Stock Units paid on 
(A) the earlier of (i) the beginning of a specified calendar year after the vesting date or (ii) their separation from 
service as a member of the Board, or (B) on the vesting date.

Directors also may elect to defer to a later year all or a portion of their remaining cash retainer or committee retainer 
fees into a stock unit account as Elective Stock Units or in alternative investment options. Elective Stock Units are 
awarded on a quarterly basis. Directors may elect to have all or a portion of their Elective Stock Units paid on the 
earlier of (i) the beginning of a specified calendar year or (ii) their separation from service as a member of the 
Board. Stock units awarded under the Director Program are paid out in an equivalent number of shares of Northrop 
Grumman common stock. Directors are credited with dividend equivalents in connection with the accumulated stock 
units until the shares of common stock relating to such stock units are issued.

Compensation Expense
Stock-based compensation expense for the years ended December 31, 2023, 2022 and 2021 was $87 million, $99 
million and $94 million, respectively. The related tax benefits (deficiencies) for stock-based compensation for the 
years ended December 31, 2023, 2022 and 2021 were $9 million, $10 million and $(2) million, respectively.

At December 31, 2023, there was $96 million of unrecognized compensation expense related to unvested stock 
awards granted under the company’s stock-based compensation plans. These amounts are expected to be charged to 
expense over a weighted-average period of 1.3 years.

The majority of our stock awards are granted annually during the first quarter. 

The grant date fair value of shares issued in settlement of fully vested stock awards was $99 million, $93 million and 
$103 million during the years ended December 31, 2023, 2022 and 2021, respectively.

Cash Awards
The company grants certain employees cash units (CUs) and cash performance units (CPUs). Depending on actual 
performance against financial objectives, recipients of CPUs earn between 0 and 200 percent of the original grant. 
The following table presents the minimum and maximum aggregate payout amounts related to those cash awards 
granted for the periods presented:

The majority of our cash awards are granted annually during the first quarter. CUs typically vest and settle in cash 
on the third anniversary of the grant date, while CPUs generally vest and pay out in cash based primarily on the 
achievement of certain performance metrics over a three-year period. At December 31, 2023, there was $116 million 
of unrecognized compensation expense related to cash awards.

FAS/CAS Operating Adjustment
For financial statement purposes, we account for our employee pension plans in accordance with FAS. However, the 
cost of these plans is charged to our contracts in accordance with applicable FAR and CAS requirements. The FAS/
CAS operating adjustment reflects the difference between CAS pension expense included as cost in segment 
operating income and the service cost component of FAS expense included in total operating income.

Unallocated Corporate (Expense) Income
Unallocated corporate (expense) income includes the portion of corporate costs not considered allowable or 
allocable under applicable FAR and CAS requirements, and therefore not allocated to the segments, such as changes 
in deferred state income taxes and a portion of management and administration, legal, environmental, compensation, 
retiree benefits, advertising and other corporate unallowable costs. Unallocated corporate (expense) income also 
includes costs not considered part of management’s evaluation of segment operating performance, such as 
amortization of purchased intangible assets and the additional depreciation expense related to the step-up in fair 
value of PP&E acquired through business combinations, as well as certain compensation and other costs.

During the first quarter of 2021, the $2.0 billion pre-tax gain on the sale of our IT services business and $192 million 
of unallowable state taxes and transaction costs associated with the divestiture were recorded in Unallocated 
corporate (expense) income.

Sales between segments are recorded at values that include intercompany operating income for the performing 
segment based on that segment’s estimated average operating margin rate for external sales. Such intercompany 
operating income is eliminated in consolidation, so that the company’s total sales and total operating income reflect 
only those transactions with external customers. See Note 1 for additional information.

reporting is based on criteria established in Internal Control—Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission. Because of its inherent limitations, a system 
of internal control over financial reporting can provide only reasonable assurance and may not prevent or detect 
misstatements. Management regularly monitors its internal control over financial reporting, and actions are taken to 
correct deficiencies as they are identified. Based on its assessment, management has concluded that the company’s 
internal control over financial reporting was effective as of December 31, 2023.

Deloitte & Touche LLP issued an attestation report dated January 24, 2024, concerning the company’s internal 
control over financial reporting, which is contained in this Annual Report. The company’s consolidated financial 
statements as of and for the year ended December 31, 2023, have been audited by the independent registered public 
accounting firm of Deloitte & Touche LLP in accordance with the standards of the Public Company Accounting 
Oversight Board (United States).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
Northrop Grumman Corporation
Falls Church, Virginia

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Northrop Grumman Corporation and subsidiaries 
(the “Company”) as of December 31, 2023, 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, 2023, based on the 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, 2023 of the 
Company and our report dated January 24, 2024 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.

Use of Non-GAAP Financial Measures

This Annual Report contains non-GAAP (accounting principles generally accepted in the United States of 
America) financial measures, as defined by Securities and Exchange Commission (SEC) Regulation G. 
While we believe investors and other users of our financial statements may find these non-GAAP financial 
measures useful in evaluating our financial performance and operational trends, they should be considered 
as supplemental in nature and therefore, should not be considered in isolation or as a substitute for 
financial information prepared in accordance with GAAP. Definitions and reconciliations for the non-GAAP 
financial measures contained in this Annual Report are provided below. Other companies may define these 
measures differently or may utilize different non-GAAP financial measures.

Adjusted Free Cash Flow:

Net cash provided by or used in operating activities, less capital expenditures, plus proceeds from the sale 
of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) 
and the after-tax impact of discretionary pension contributions, if any. Adjusted free cash flow includes 
proceeds from the sale of equipment to a customer as such proceeds were generated in a customer sales 
transaction. It also includes the after tax impact of discretionary pension contributions for consistency and 
comparability of financial performance. We use adjusted free cash flow as a key factor in our planning for, 
and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP 
measure may be useful to investors and other users of our financial statements as a supplemental measure 
of our cash performance, but should not be considered in isolation, as a measure of residual cash flow 
available for discretionary purposes, or as an alternative to operating cash flows presented in accordance 
with GAAP.
