Table of Contents
Statements we make in this Annual Report on Form 10-K ("Report"), which express a belief, expectation or intention, as well as those that are not historical fact, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to various risks, uncertainties and assumptions, including those to which we refer under the headings "Cautionary Statement Concerning Forward-Looking Statements" and "Risk Factors" in Items 1 and 1A of Part I of this Report. In this Report, unless the context otherwise indicates, "we," "us" and "our" mean BWX Technologies, Inc. ("BWXT" or the "Company") and its consolidated subsidiaries.
PART I
Item 1. BUSINESS
General
BWX Technologies, Inc. is a specialty manufacturer of nuclear components, a developer of nuclear technologies and a service provider with an operating history of more than 100 years. Our core businesses focus on the design, engineering and manufacture of precision naval nuclear components, reactors and nuclear fuel for the U.S. Government. We also provide special nuclear materials processing, environmental site restoration services, and a variety of products and services to customers in the nuclear power industry, as well as critical medical radioisotopes and radiopharmaceuticals. While we provide a wide range of products and services, our business segments are heavily focused on major projects. At any given time, a relatively small number of projects can represent a significant part of our operations.
On June 30, 2015, we completed the spin-off of our former Power Generation business (the "spin-off") into an independent, publicly traded company named Babcock & Wilcox Enterprises, Inc. ("BWE"). We have presented the notes to our consolidated financial statements on the basis of continuing operations, unless otherwise stated.
Business Segments
We operate in three reportable segments: Nuclear Operations Group, Nuclear Power Group and Nuclear Services Group. For financial information regarding each of our segments and financial information regarding geographic areas, see Note 15 to our consolidated financial statements included in this Report. For further details regarding each segment's facilities, see Item 2, "Properties." In general, we operate in capital-intensive industries and rely on large contracts for a substantial amount of our revenues. We are currently exploring growth strategies across our segments through strategic investments and acquisitions to expand and complement our existing businesses. We would expect to fund these opportunities with cash generated from operations or by raising additional capital through debt, equity or some combination thereof.
Nuclear Operations Group
Through this segment, we engineer, design and manufacture precision naval nuclear components, reactors and nuclear fuel for the U.S. Department of Energy ("DOE")/National Nuclear Security Administration's ("NNSA") Naval Nuclear Propulsion Program. In addition, we perform fabrication activities for missile launch tubes for U.S. Navy submarines.
Our Nuclear Operations Group segment specializes in the design and manufacture of close-tolerance and high-quality equipment for nuclear applications. In addition, we are a leading manufacturer of critical nuclear components, fuels and assemblies for government and limited other uses. We have supplied nuclear components for DOE programs since the 1950s and are the largest domestic supplier of research reactor fuel elements for colleges, universities and national laboratories. We also downblend Cold War-era government stockpiles of high-enriched uranium. In addition, we have over 100 years of experience in supplying components for defense applications.
We work closely with the DOE-supported nuclear non-proliferation program. Currently, this program is assisting in the development of a high-density, low-enriched uranium fuel required for high-enriched uranium test reactor conversions. We have also been a leader in the receipt, storage, characterization, dissolution, recovery and purification of a variety of uranium-bearing materials. All phases of uranium downblending and uranium recovery are performed at our Lynchburg, Virginia and Erwin, Tennessee sites.
The demand for nuclear components by the U.S. Government determines a substantial portion of this segment's backlog. We expect that orders for nuclear components will continue to be a significant part of backlog for the foreseeable future. In addition, the U.S. Navy issued its fiscal year 2022 long-range shipbuilding plan in December 2020, which maintains recommendations made in its fiscal year 2020 long-range shipbuilding plan (released in September 2019) to increase the size of its fleet of ships to include additional submarines and aircraft carriers beyond the number disclosed prior to September 2019.

Table of Contents
While the new Administration may make further changes with its fiscal year 2022 budget submission, we have made additional capital expenditures and investments in personnel to meet this anticipated growth in demand and we expect to continue making such expenditures and investments.
Nuclear Power Group
Through this segment, we design and manufacture commercial nuclear steam generators, heat exchangers, pressure vessels, reactor components and other auxiliary equipment, including containers for the storage of spent nuclear fuel and other high-level nuclear waste. We have supplied the nuclear industry with more than 1,300 large, heavy components worldwide and we are the only commercial heavy nuclear component manufacturer in North America. This segment is also a leading supplier of nuclear fuel, fuel handling systems, tooling delivery systems, nuclear-grade materials and precisely machined components, and related services for CANDU nuclear power plants. This segment also provides a variety of engineering and in-plant services and is a significant supplier to nuclear power utilities undergoing major refurbishment and plant life extension projects. Our in-depth knowledge comes from over 50 years of experience in the design, manufacturing, commissioning and service of nuclear power generation equipment. Additionally, this segment is a leading global manufacturer and supplier of critical medical radioisotopes and radiopharmaceuticals.
The Nuclear Power Group segment specializes in performing full-scope, prototype design work coupled with manufacturing integration. This segment's capabilities include:

•material procurement of tubing, forgings and weld wire;
•metallographic and chemical analysis; and
•manufacture and supply of critical medical radioisotopes and radiopharmaceuticals for research, diagnostic and therapeutic uses.
Our Nuclear Power Group segment's overall activity primarily depends on the demand and competitiveness of nuclear energy. A significant portion of our Nuclear Power Group segment's operations depends on the timing of maintenance outages, principally in the Canadian market, and the cyclical nature of capital expenditures and major refurbishments for nuclear utility customers, which could cause variability in our financial results.
Nuclear Services Group
Through this segment, we provide various services to the U.S. Government, including special nuclear materials processing, environmental site restoration services and management and operating services for various U.S. Government-owned facilities. These services are provided primarily to the DOE, including the NNSA, the Office of Nuclear Energy, the Office of Science and the Office of Environmental Management, and NASA.
This segment's principal operations include:
•managing and operating environmental management sites;
•managing spent nuclear fuel and transuranic waste for the DOE;
•managing and operating nuclear production facilities;

Table of Contents
This segment also develops technology for a variety of applications, including advanced nuclear power sources, and offers complete advanced nuclear fuel and reactor design and engineering, licensing and manufacturing services for new advanced nuclear reactors.
Our Nuclear Services Group segment's overall activity depends primarily on authorized spending levels of the DOE, including the NNSA, the Office of Nuclear Energy, the Office of Science and the Office of Environmental Management, and NASA. We manage and operate complex, high-consequence nuclear and national security operations for the DOE and the NNSA, primarily through our joint ventures, as further discussed under the caption "Joint Ventures" below.
Divestiture of U.S.-Based Commercial Nuclear Services Business
On May 29, 2020, our subsidiary BWXT Nuclear Energy, Inc. divested its U.S.-based commercial nuclear services business, a component of our Nuclear Services Group segment. In a cashless transaction, we exchanged net assets totaling $18.0 million, consisting primarily of property, plant and equipment and certain warranty obligations, for a manufacturing facility and the associated land of approximately the same value. The acquired assets are reported as part of the Nuclear Services Group segment.
Acquisitions
Laker Energy Products Ltd.
On January 2, 2020, our subsidiary BWXT Canada Ltd. acquired Laker Energy Products Ltd. ("Laker Energy Products"). Laker Energy Products is a global supplier of nuclear-grade materials and precisely machined components for CANDU nuclear power utilities and employs approximately 140 personnel. Laker Energy Products is reported as part of our Nuclear Power Group segment.
Nordion Medical Isotope Business
On July 30, 2018, our subsidiary BWXT ITG Canada, Inc. acquired the Nordion medical isotope business (the "MI business"). The MI business is a leading global manufacturer and supplier of critical medical radioisotopes and radiopharmaceuticals for research, diagnostic and therapeutic uses. Its customers include radiopharmaceutical companies, hospitals and radiopharmacies. Its primary operations are located in Kanata, Ontario, Canada and Vancouver, British Columbia, Canada. This acquisition added approximately 150 highly trained and experienced personnel, two specialized production centers and a uniquely licensed infrastructure. In addition to the growing portfolio of radioisotope products we acquired, the MI business will be the platform from which we plan to launch our Molybdenum-99 product line and a number of future radioisotope-based imaging, diagnostic and therapeutic products. This business is reported as part of our Nuclear Power Group segment.
See Note 2 to our consolidated financial statements included in this Report for additional information on acquisitions.
Contracts
We execute our contracts through a variety of methods, including fixed-price incentive fee, cost-plus, cost-reimbursable, firm fixed-price or some combination of these methods. We generally recognize our contract revenues and related costs on an over time basis. Accordingly, we review contract price and cost estimates regularly as the work progresses and reflect adjustments in profit proportionate to the percentage of completion in the period when we revise those estimates. To the extent that these adjustments result in a reduction or an elimination of previously reported profits with respect to a project, we would recognize a charge against current earnings, which could be material.
We have contracts that extend beyond one year. Most of our long-term contracts have provisions for progress payments. We attempt to cover anticipated increases in labor, material and service costs of our long-term contracts either through an estimate of such changes, which is reflected in the original price, or through risk-sharing mechanisms, such as escalation or price adjustments for items such as labor and commodity prices.
In the event of a contract deferral or cancellation, we generally would be entitled to recover costs incurred, settlement expenses and profit on work completed prior to deferral or termination. Significant or numerous cancellations could adversely affect our business, financial condition, results of operations and cash flows.

Table of Contents
Nuclear Operations Group
The majority of the revenue generated by this segment is from long-term contracts with the U.S. DOE/NNSA's Naval Nuclear Propulsion Program. Unless otherwise specified in a contract, allowable and allocable costs are billed to contracts with the U.S. Government in accordance with the Federal Acquisition Regulation (the "FAR") and the related U.S. Government Cost Accounting Standards ("CAS"). Examples of costs that may be incurred by us and not billable to the U.S. Government in accordance with the requirements of the FAR and CAS regulations include, but are not limited to, unallowable employee compensation and benefit costs, lobbying costs, interest, certain legal costs and charitable donations.
Most of our contracts in this segment are fixed-price incentive fee contracts that provide for reimbursement of allowable costs incurred plus a fee and generally require that we use our best efforts to accomplish the scope of the work within some specified time and stated dollar limitation. Fees can be established in terms of dollar value or percentage of costs. Award and incentive fees are determined and earned based on customer evaluation of our performance against negotiated criteria, primarily related to cost, and are intended to provide motivation for excellence in contract performance. Incentive fees that are based on cost provide for an initially negotiated fee to be adjusted later, typically using a formula to measure performance against the associated criteria, based on the relationship of total allowable costs to total target costs. Award and incentive fees represent variable consideration that we include in revenue when there is sufficient evidence to determine that the variable consideration is not constrained.
Certain of our U.S. Government contracts span one or more base years and multiple option years. The U.S. Government generally has the right not to exercise option periods and may not exercise an option period for various reasons including, but not limited to, annual funding determinations. In addition, contracts between the U.S. Government and its prime contractors usually contain standard provisions for termination at the convenience of the U.S. Government or the prime contractor. As a U.S. Government contractor, we are subject to federal regulations under which our right to receive future awards of new federal contracts would be unilaterally suspended or barred if we were convicted of a crime or indicted based on allegations of a violation of specific federal statutes. In addition, some of our contracts with the U.S. Government require us to provide advance notice in connection with any contemplated sale or shut down of the relevant facility. In each of those situations, the U.S. Government has an exclusive right to negotiate a mutually acceptable purchase of the facility.
Nuclear Power Group
Contracts in this segment are usually awarded through a competitive bid process. Factors that customers may consider include price, plant or equipment availability, technical capabilities of equipment and personnel, efficiency, safety record and reputation. Certain of these contracts are fixed-price contracts in which the specified scope of work is agreed to for a pre-determined price that is generally not subject to adjustment, regardless of costs incurred by the contractor, unless changes in scope are authorized by the customer. Fixed-price contracts entail more risk to us because they require us to predetermine both the quantities of work to be performed and the costs associated with executing the work. Remaining contracts are primarily time-and-materials contracts, which result in us recovering costs incurred in accordance with the contract plus a fee.
Our arrangements with customers may require us to provide letters of credit, bid and performance bonds or guarantees to secure bids or performance under contracts, which may involve significant amounts for contract security.
Nuclear Services Group
This segment's principal operations include the management and operation of nuclear production facilities, environmental management sites and the management of spent nuclear fuel and transuranic waste for the DOE. These activities are primarily accomplished through our participation in joint ventures with other contractors as further discussed under the caption "Joint Ventures" below.
The contracts for the management and operation of U.S. Government facilities are awarded through a complex and protracted procurement process. These contracts are generally structured as five-year contracts with options for up to five additional years, which are exercisable by the customer, or include provisions whereby the contract durations can be extended as a result of the achievement of certain performance metrics. These are generally cost-reimbursement contracts that include an award fee that is primarily based on annual performance, with monthly provisional fee payments and annual true-up payments. Depending on the type of contract, the contractor may be required to supply working capital, which is reimbursed by the U.S. Government through regular invoicing.
This segment also serves customers of our advanced technology platforms primarily through the use of fixed-price contracts that are awarded following a competitive bid process. Fixed-price contracts entail more risk to us because the price

has been pre-determined and is generally not subject to adjustment, regardless of costs incurred, unless authorized by the customer.
Backlog
Backlog represents the dollar amount of revenue we expect to recognize in the future from contracts awarded and in progress. Not all of our expected revenue from a contract award is recorded in backlog for a variety of reasons, including that some projects are awarded and completed within the same reporting period.
Our backlog is equal to our remaining performance obligations under contracts that meet the criteria in Financial Accounting Standards Board ("FASB") Topic Revenue from Contracts with Customers, as discussed in Note 3 to our consolidated financial statements included in this Report. It is possible that our methodology for determining backlog may not be comparable to methods used by other companies.
We are subject to the budgetary and appropriations cycle of the U.S. Government as it relates to our Nuclear Operations Group and Nuclear Services Group segments. Backlog may not be indicative of future operating results, and projects in our backlog may be cancelled, modified or otherwise altered by customers.
Our backlog at December 31, 2020 and 2019 was as follows:

|  | December 31, 2020 |  | December 31, 2019
|  | (In approximate millions)
Nuclear Operations Group |  | $ | 3,659 |  |  | 83 | % |  | $ | 4,515 |  |  | 85 | %
Nuclear Power Group |  | 726 |  |  | 16 | % |  | 730 |  |  | 14 | %
Nuclear Services Group |  | 21 |  |  | 1 | % |  | 43 |  |  | 1 | %
Total Backlog |  | $ | 4,406 |  |  | 100 | % |  | $ | 5,288 |  |  | 100 | %

We do not include the value of our unconsolidated joint venture contracts in backlog. These unconsolidated joint ventures are included in our Nuclear Services Group segment. See Note 4 to our consolidated financial statements included in this Report for financial information on our equity method investments.
Of the backlog at December 31, 2020, we expect to recognize revenues as follows:

|  | 2021 |  | 2022 |  | Thereafter |  | Total
|  | (In approximate millions)
Nuclear Operations Group |  | $ | 1,221 |  |  | $ | 919 |  |  | $ | 1,519 |  |  | $ | 3,659 |
Nuclear Power Group |  | 307 |  |  | 171 |  |  | 248 |  |  | 726 |
Nuclear Services Group |  | 21 |  |  | — |  |  | — |  |  | 21 |
Total Backlog |  | $ | 1,549 |  |  | $ | 1,090 |  |  | $ | 1,767 |  |  | $ | 4,406 |

As of December 31, 2020, our Nuclear Operations Group segment's backlog with the U.S. Government was $3,248.7 million, $391.1 million of which had not yet been funded.
As of December 31, 2020, our Nuclear Power Group segment had no backlog with the U.S. Government.
As of December 31, 2020, our Nuclear Services Group segment's backlog with the U.S. Government was $18.6 million, all of which has been funded.
Major new awards from the U.S. Government are typically received following Congressional approval of the budget for the U.S. Government's next fiscal year, which starts October 1, and may not be awarded to us before the end of the calendar year. Due to the fact that most contracts awarded by the U.S. Government are subject to these annual funding approvals, the total values of the underlying programs are significantly larger. In 2019, we received awards from the U.S. Government with a combined value in excess of $3.9 billion, inclusive of unexercised options, approximately $3.4 billion of which had been added to backlog as of December 31, 2020. The value of unexercised options excluded from backlog as of December 31, 2020 was approximately $0.5 billion, which is expected to be exercised through 2025, subject to annual Congressional appropriations.

Although shortages of some raw materials have existed occasionally, no serious shortage exists at the present time.
Our Nuclear Operations Group segment relies on several single-source suppliers for materials used in its products. We believe these suppliers are reliable, and we and the U.S. Government expend significant effort to monitor and maintain the supplier base for our Nuclear Operations Group segment. Our Nuclear Power Group and Nuclear Services Group segments do not depend on single sources of supply for materials used in their products. We have limited supply options for certain raw materials used in our Nuclear Power Group segment; however, we believe the suppliers of these materials are reliable.
Human Capital Management
Employees. At December 31, 2020, we employed approximately 6,700 persons worldwide, predominantly in the U.S. (5,400 employees) and Canada (1,300 employees). Many of our operations are subject to union contracts, which we customarily renew periodically. At December 31, 2020, approximately 1,700 of our employees were members of labor unions. We consider our relationships with our employees to be satisfactory.
Diversity and Inclusion. We value the diversity of our employees and are committed to providing an engaging and inclusive atmosphere for all employees that promotes productivity and encourages creativity and innovation. We strive to maintain a highly-skilled and diverse workforce where employees are hired, retained, compensated and promoted based on their performance and contribution to the Company.

Employee Development and Retention. The attraction, development and retention of our employees is a key focus for our Company. We offer online and in-person training programs to enhance the knowledge, skills and advancement opportunities for our employees. Our goal is to be the employer of choice within our industry and the communities in which we operate. We focus on maintaining a solid pipeline of talent throughout our organization and continually developing the capabilities and skills needed for the future of our business.
Work Environment. We believe that maintaining a work environment that recognizes effort and teamwork, values mutual respect and open communication, and demonstrates care and concern for our employees is essential to an engaged and productive workforce. In furtherance of this objective, we provide regular Code of Business Conduct training for our employees to identify and prevent misconduct and report situations that violate our policies and/or negatively impact our work environment. We investigate and take prompt action to correct conduct that is inconsistent with our Code of Business Conduct and other policies.
Health and Safety. The safety of our employees is critical to our success as a specialty manufacturer of nuclear components and an operator of high-consequence nuclear and national security facilities for the U.S. Government. As such, we are committed to maintaining the highest safety, security, ethical and environmental standards. We take pride in the fact that we operate NRC Category 1 and Canadian Nuclear Safety Commission ("CNSC") licensed facilities and have instilled as a core value a culture that prioritizes safety with a vision of zero accidents at these and all of our work locations. In pursuit of an injury-free workplace, we constantly monitor and assess all injuries and "near misses" for any lessons we can learn and leverage to reduce the risk inherent in occupational activities. We use this information to further develop our safety program in an effort to prevent future occupational and environmental incidents to help us achieve our safety goals.
During 2020, as an essential business we implemented safety protocols and new procedures to protect our employees and contractors in response to the novel strain of coronavirus ("COVID-19") pandemic. These protocols included complying with social distancing and other health and safety standards as required by federal, state and local government agencies, taking into consideration guidelines of the Centers for Disease Control and Prevention and other public health authorities. For a detailed discussion of the impact of the COVID-19 pandemic, see "COVID-19 Assessment" in Item 7 of this Report.
Patents and Technology Licenses
We currently hold a large number of U.S. and foreign patents and have patent applications pending in certain technologies, including nuclear reactor systems, components and fuel, advanced and additive manufacturing, space nuclear propulsion, and radioisotope production. We acquire patents and technology licenses and grant licenses to others when we consider it advantageous for us to do so. Although in the aggregate our patents and technology licenses are important to us, we do not regard any single patent or license or group of related patents or licenses as critical or essential to our business as a whole. In general, we depend on our technological capabilities and the application of know-how, rather than patents and technology licenses, in the conduct of our various businesses.
Research and Development Activities
Our research and development activities are related to the development and improvement of new and existing products and equipment, as well as conceptual and engineering evaluation for translation into practical applications. These activities include the development of isotope production, medical radiochemical and radiopharmaceutical production and a variety of advanced technologies in the areas of additive and autonomous manufacturing, space nuclear power and propulsion, and high-temperature gas-cooled reactors, among others. These projects are sponsored and funded through internal research and development and by a number of commercial and government customers.
We charge the costs of research and development unrelated to specific contracts as incurred. Excluding customer-sponsored research and development, the majority of our activities in this area for the years ended December 31, 2020, 2019 and 2018 related to the development of technologies in the area of medical and industrial radioisotopes and additive and autonomous manufacturing. Contractual arrangements for customer-sponsored research and development can vary on a case-by-case basis and include contracts, cooperative agreements and grants.
See Note 1 to our consolidated financial statements included in this Report for further information on research and development.

Hazard Risks and Insurance
Our operations present risks of injury to or death of people, loss of or damage to property and damage to the environment. We have created loss control systems and processes to assist us in the identification and treatment of the hazard risks presented by our operations, and we endeavor to make sure these systems are effective.
As loss control measures will not always be successful, we seek to establish various means of funding losses and transferring financial liability related to incidents or occurrences. We primarily seek to do this through contractual protections, including waivers of consequential damages, indemnities, caps on liability, liquidated damages provisions and access to the insurance of other parties. We also procure insurance, operate our own captive insurance company and/or establish funded or unfunded reserves. However, none of these methods will eliminate all risks.
Depending on competitive conditions, the nature of the work, industry custom and other factors, we may not be successful in obtaining adequate contractual protection from our customers and other parties against losses and liabilities arising out of or related to the performance of our work. The scope of the protection may be limited, may be subject to conditions and may not be supported by adequate insurance or other means of financing. In addition, we may have difficulty enforcing our contractual rights with others following a material loss.
Similarly, insurance for certain potential losses or liabilities may not be available or may only be available at a cost or on terms we consider not to be economical. Insurers frequently react to market losses by ceasing to write or severely limiting coverage for certain exposures. Risks that we have frequently found difficult to cost-effectively insure against include, but are not limited to, property losses from wind, flood and earthquake events, nuclear hazards and war, pollution liability, liabilities related to occupational health exposures (including asbestos), liability related to our executives, professional liability/errors and omissions coverage, the failure, misuse or unavailability of our information technology systems, the failure of security measures designed to protect our information technology systems from security breaches and liability related to risk of loss of our work in progress. In cases where we purchase insurance, we are subject to the creditworthiness of the relevant insurer(s), the available limits of the coverage, our retention under the relevant policy, exclusions in the policy and gaps in coverage.
Our operations in designing, engineering, manufacturing, constructing and servicing nuclear power equipment and components for our commercial nuclear utility customers subject us to various risks, including, without limitation, damage to our customers' property and third-party claims for personal injury, environmental liability, death and property damage. To protect against liability for damage to a customer's property, we endeavor to obtain waivers of liability and subrogation from the customer and its insurer. We also attempt to cap our overall liability in our contracts. To protect against liability from claims brought by third parties, we seek to be insured under the utility customer's nuclear liability policies and have the benefit of the indemnity and limitation of any applicable liability provision of the Price-Anderson Act. The Price-Anderson Act limits the public liability of U.S. manufacturers and operators of licensed nuclear facilities and other parties who may be liable in respect of, and indemnifies them against, all claims in excess of a certain amount. This amount is determined by the sum of commercially available liability insurance plus certain retrospective premium assessments payable by operators of commercial nuclear reactors. For those sites where we provide environmental remediation services, we seek the same protection from our customers as we do for our other nuclear activities. The Price-Anderson Act, as amended, includes a sunset provision and requires renewal each time that it expires. Contracts that were entered into during a period of time that the Price-Anderson Act was in full force and effect continue to receive the benefit of the Price-Anderson Act's nuclear indemnity. The Price-Anderson Act is set to expire on December 31, 2025. We also provide nuclear fabrication and other services to the nuclear power industry in Canada. Canada's Nuclear Liability and Compensation Act ("NLCA") generally conforms to international conventions and is conceptually similar to the Price-Anderson Act in the U.S. Accordingly, indemnification protections and the possibility of exclusions under Canada's NLCA are similar to those under the Price-Anderson Act in the U.S.
We supply commercial nuclear equipment and services to certain customers in countries other than the U.S. and Canada that are party to international treaties and in countries that are not signatory to international treaties but have their own nuclear liability laws that, in general, have regulations in place whereby nuclear operators are solely liable for nuclear damage claims, which would exclude nuclear suppliers from any such exposure. BWXT does retain some level of risk in the event of future changes to the legal landscape in these countries regarding international third-party nuclear liability.
In 2008, the U.S. ratified the Convention on Supplementary Compensation for Nuclear Damage ("CSC") with the International Atomic Energy Agency. The CSC is an international treaty developed to create a global legal framework for allocating responsibility and assuring prompt and equitable compensation in the unlikely event of certain nuclear incidents. The ratification by the U.S. authorizes the Secretary of Energy to issue regulations establishing a retrospective risk pooling program whereby, in the event that the U.S. must make a contribution to the CSC international fund, U.S. nuclear suppliers, including BWXT, would pay the full cost of this contribution by the U.S.

Table of Contents
Although we do not own or operate any nuclear reactors, we have some coverage under commercially available nuclear liability and property insurance for our facilities that are currently licensed to possess special nuclear materials. Substantially all of our Nuclear Operations Group segment contracts involving nuclear materials are covered by and subject to the nuclear indemnity provisions of either the Price-Anderson Act or Public Law 85-804, which, among other things, authorizes the DOE to indemnify certain contractors when such acts would facilitate national defense. However, to the extent the value of the nuclear materials in our care, custody or control exceeds the commercially available limits of our insurance, we potentially have underinsured risk of loss for such nuclear material.
Our Nuclear Services Group segment participates in the management and operation of various U.S. Government facilities. This participation is customarily accomplished through the participation in joint ventures with other contractors for any given facility. These activities involve, among other things, handling nuclear devices and their components. Insurable liabilities arising from these sites are rarely protected by our or our partners' corporate insurance programs. Instead, we rely on government contractual agreements and insurance purchased specifically for a site. The U.S. Government has historically fulfilled its contractual agreement to reimburse its contractors for covered claims, and we expect it to continue this process during our participation in the management and operation of these facilities. However, in most of these situations in which the U.S. Government is contractually obligated to pay, the payment obligation is subject to the availability of authorized government funds. The reimbursement obligation of the U.S. Government is also conditional, and provisions of the relevant contract or applicable law may preclude reimbursement.
Our wholly owned captive insurance subsidiary provides primary workers' compensation, employer's liability, commercial general liability and automotive liability insurance to support our operations. We may also have business reasons in the future to have our insurance subsidiary accept other risks that we cannot or do not wish to transfer to outside insurance companies. These risks may be considerable in any given year or cumulatively. Our insurance subsidiary does not provide insurance to unrelated parties. Claims as a result of our operations could adversely impact the ability of our insurance subsidiary to respond to all claims presented.
Additionally, upon the February 22, 2006 effectiveness of the settlement relating to the Chapter 11 proceedings involving several of our former subsidiaries, most of our subsidiaries contributed substantial insurance rights to the asbestos personal injury trust, including rights to (1) certain pre-1979 primary and excess insurance coverages and (2) certain of our 1979-1986 excess insurance coverage. These insurance rights provided coverage for, among other things, asbestos and other personal injury claims, subject to the terms and conditions of the policies. The contribution of these insurance rights was made in exchange for the agreement on the part of the representatives of the asbestos claimants, including the representative of future claimants, to the entry of a permanent injunction, pursuant to Section 524(g) of the U.S. Bankruptcy Code, to channel to the asbestos trust all asbestos-related general liability claims against our subsidiaries and former subsidiaries arising out of, resulting from or attributable to their operations, and the implementation of related releases and indemnification provisions protecting those subsidiaries and their affiliates from future liability for such claims. Although we are not aware of any significant, unresolved claims against our subsidiaries and former subsidiaries that are not subject to the channeling injunction and that relate to the periods during which such excess insurance coverage related, with the contribution of these insurance rights to the asbestos personal injury trust, it is possible that we could have underinsured or uninsured exposure for non-derivative asbestos claims or other personal injury or other claims that would have been insured under these coverages had the insurance rights not been contributed to the asbestos personal injury trust. In conjunction with the spin-off, claims and liabilities associated with the asbestos personal injury, property damage and indirect property damage claims mentioned above have been expressly assumed by BWE pursuant to the master separation agreement between us and BWE.
Governmental Regulations and Environmental Matters
Governmental Regulations
Many aspects of our operations and properties are affected by political developments and are subject to both domestic and foreign governmental regulations, including those relating to:
•possessing and processing special nuclear materials;
•workplace health and safety;
•constructing and equipping electric power facilities;
•currency conversions and repatriation;
•taxation of earnings; and
•protecting the environment.

Table of Contents
We are required by various governmental and quasi-governmental agencies to obtain certain permits, licenses and certificates with respect to our operations. The kinds of permits, licenses and certificates required in our operations depend upon a number of factors.
We cannot determine the extent to which new legislation, new regulations or changes in existing laws or regulations may affect our future operations.
Environmental
Our operations and properties are subject to a wide variety of increasingly complex and stringent federal, foreign, state and local environmental laws and regulations, including those governing discharges into the air and water, the handling and disposal of solid and hazardous wastes, the remediation of soil and groundwater contaminated by hazardous substances and the health and safety of employees. Sanctions for non-compliance may include revocation of permits, corrective action orders, administrative or civil penalties and criminal prosecution. Some environmental laws provide for strict, joint and several liability for remediation of spills and other releases of hazardous substances, as well as damage to natural resources. In addition, companies may be subject to claims alleging personal injury or property damage as a result of alleged exposure to hazardous substances. Such laws and regulations may also expose us to liability for the conduct of or conditions caused by others or for our acts that were in compliance with all applicable laws at the time such acts were performed.
These laws and regulations include the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended ("CERCLA"), the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act and similar laws that provide for responses to, and liability for, releases of hazardous substances into the environment. These laws and regulations also include similar foreign, state or local counterparts to these federal laws, which regulate air emissions, water discharges, hazardous substances and waste and require public disclosure related to the use of various hazardous substances. Our operations are also governed by laws and regulations relating to workplace safety and worker health, including the U.S. Occupational Safety and Health Act and regulations promulgated thereunder.
We are currently in the process of investigating and remediating some of our current and former operating sites. Although we have recorded reserves in connection with certain of these environmental matters, due to the uncertainties associated with environmental remediation, there can be no assurance that the actual costs resulting from these remediation matters will not exceed the recorded reserves.
Our compliance with federal, foreign, state and local environmental control and protection regulations resulted in pre-tax charges of approximately $16.3 million, $15.9 million and $14.7 million in the years ended December 31, 2020, 2019 and 2018, respectively. In addition, compliance with existing environmental regulations necessitated capital expenditures of $1.2 million, $1.4 million and $1.7 million in the years ended December 31, 2020, 2019 and 2018, respectively. We expect to spend another $11.4 million on such capital expenditures over the next five years. We cannot predict all of the environmental requirements or circumstances that will exist in the future, but we anticipate that environmental control and protection standards will become increasingly stringent and costly. Based on our experience to date, we do not currently anticipate any material adverse effect on our business or consolidated financial condition as a result of future compliance with existing environmental laws and regulations. However, future events, such as changes in existing laws and regulations or their interpretation, more vigorous enforcement policies of regulatory agencies or stricter or different interpretations of existing laws and regulations, may require additional expenditures by us, which may be material. Accordingly, we can provide no assurance that we will not incur significant environmental compliance costs in the future.
We have been identified as a potentially responsible party at various cleanup sites under CERCLA. CERCLA and other environmental laws can impose liability for the entire cost of cleanup on any of the potentially responsible parties, regardless of fault or the lawfulness of the original conduct. Generally, however, where there are multiple responsible parties, a final allocation of costs is made based on the amount and type of wastes disposed of by each party and the number of financially viable parties, although this may not be the case with respect to any particular site. We have not been determined to be a major contributor of wastes to any of these sites. On the basis of the relative contribution of waste to each site by potentially responsible parties, as well as the financial solvency of other potentially responsible parties, we expect our share of the ultimate liability for the various sites will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows in any given year.
Environmental remediation projects have been and continue to be undertaken at certain of our current and former facilities. In 2002, Congress directed the U.S. Army Corps of Engineers ("Army Corps") to clean up radioactive waste at the Shallow Land Disposal Area located in Parks Township, Armstrong County, Pennsylvania (the "SLDA"), consistent with the Memorandum of Understanding between the NRC and the Army Corps for Coordination on Cleanup and Decommissioning of
11

Table of Contents
the Formerly Utilized Sites Remedial Action Program Sites with NRC-Licensed Facilities, dated July 5, 2001 (the "MOU"). From 1961 to 1970, the SLDA was operated by the Nuclear Materials and Equipment Corporation ("NUMEC") pursuant to Atomic Energy Commission ("AEC") License SNM-145. The AEC was the predecessor to the NRC. The SLDA was used for the disposal of waste from NUMEC's nuclear fuels fabrication facility in Apollo, Pennsylvania. Both radioactive and non-radioactive waste was disposed in a series of trenches at the SLDA. NUMEC, a former subsidiary of Atlantic Richfield Company ("ARCO") was acquired by BWXT in November 1971. Shortly after the Army Corps' contractor commenced cleanup operations in 2011, the Army Corps ceased excavation activities because the contractor deviated from accepted field procedures, and the excavated material was found to be complex and beyond the Army Corps' characterization and management procedures. The MOU was modified in late 2014 to add the DOE and the NNSA as parties to deal with "special nuclear materials." In December 2014, the Army Corps issued a Proposed Record of Decision Amendment, which reflects a revised cost estimate of $350 million, in addition to the $62 million expended through September 2014, to implement the selected remedy. In October 2018, the Army Corps confirmed award of the previously protested remediation contract as amended to the original contractor. In March 2019, the Army Corps issued a notice-to-proceed to this contractor. The federal legislation directing the Army Corps to clean up the SLDA also directs the Army Corps to seek to recover response costs from appropriate responsible parties in accordance with CERCLA. In connection with BWXT's acquisition of NUMEC from ARCO in November 1971, ARCO assumed and agreed to indemnify and hold harmless BWXT with respect to claims and liabilities arising as a result of transactions or operations of NUMEC prior to the acquisition date. Although this ARCO indemnity would cover claims by the Army Corps to seek recovery from BWXT for SLDA cleanup costs, no assurance can be given that this indemnity will be available or sufficient in the event such claims are asserted. For additional discussion of environmental matters, see "Note 10 – Commitments and Contingencies" to our consolidated financial statements included in this Report.
We perform significant amounts of work for the U.S. Government under both prime contracts and subcontracts and operate certain facilities that are licensed to possess and process special nuclear materials. As a result of these activities, we are subject to continuing reviews by governmental agencies, including the U.S. Environmental Protection Agency and the NRC. We are also involved in manufacturing activities at licensed facilities in Canada that are also subject to continuing reviews by governmental agencies in Canada, including the CNSC.
The NRC's decommissioning regulations require our Nuclear Operations Group segment to provide financial assurance that it will be able to pay the expected cost of decommissioning its two licensed facilities at the end of their service lives. We provided financial assurance totaling $61.8 million during the years ended December 31, 2020 and 2019 with surety bonds for the ultimate decommissioning of these licensed facilities. These facilities have provisions in their government contracts pursuant to which substantially all of our decommissioning costs and financial assurance obligations are covered by the DOE, including the costs to complete the decommissioning projects underway at the facility in Erwin, Tennessee. The surety bonds noted above are to cover decommissioning required pursuant to work not subject to this DOE obligation.
In Canada, the CNSC's decommissioning regulations require our Nuclear Power Group segment to provide financial assurance that it will be able to pay the expected cost of decommissioning its CNSC-licensed facilities at the end of their service lives. We provided financial assurance totaling $47.9 million and $47.0 million during the years ended December 31, 2020 and 2019, respectively, with letters of credit and surety bonds for the ultimate decommissioning of these licensed facilities.
At December 31, 2020 and 2019, we had total environmental accruals, including asset retirement obligations, of $91.3 million and $90.8 million, respectively. Of our total environmental accruals at December 31, 2020 and 2019, $7.1 million and $10.4 million, respectively, were included in current liabilities. Inherent in the estimates of these accruals are our expectations regarding the levels of contamination, decommissioning costs and recoverability from other parties, which may vary significantly as decommissioning activities progress. Accordingly, changes in estimates could result in material adjustments to our operating results, and the ultimate loss may differ materially from the amounts we have provided for in our consolidated financial statements.
Cautionary Statement Concerning Forward-Looking Statements
From time to time, our management or persons acting on our behalf make forward-looking statements to inform existing and potential security holders about our Company. Statements and assumptions regarding expectations and projections of specific projects, our future backlog, revenues, income and capital spending, strategic investments, acquisitions or divestitures, return of capital activities, margin improvement initiatives or impacts of the COVID-19 pandemic are examples of forward-looking statements. Forward-looking statements are generally accompanied by words such as "estimate," "project," "predict," "believe," "expect," "anticipate," "plan," "seek," "goal," "could," "intend," "may," "should" or other words that convey the uncertainty of future events or outcomes. In addition, sometimes we will specifically describe a statement as being a forward-looking statement and refer to this cautionary statement.
12

Table of Contents
Statements in this Report, including those that express a belief, expectation or intention, as well as those that are not statements of historical fact, are forward-looking statements. Those forward-looking statements appear in Item 1 – "Business" and Item 3 – "Legal Proceedings" in Part I of this Report, in Item 7 – "Management's Discussion and Analysis of Financial Condition and Results of Operations" and in the notes to our consolidated financial statements in Item 8 of Part II of this Report and elsewhere in this Report.
We have based our forward-looking statements on information currently available to us and our current expectations, estimates and projections about our industries and our Company. We caution that these statements are not guarantees of future performance, and you should not rely unduly on them as they involve risks, uncertainties and assumptions that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. For example, the extent to which the COVID-19 outbreak will continue to impact our business will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the length and severity of the COVID-19 health crisis, and the actions to contain its impact, in addition to the potential recurrence or subsequent waves or strains of COVID-19 or similar diseases. While our management considers these statements and assumptions to be reasonable, they are inherently subject to numerous factors, including potentially the risk factors described in the section labeled Item 1A, "Risk Factors" of this Report, most of which are difficult to predict and many of which are beyond our control. Accordingly, our actual results may differ materially from the future performance that we have expressed or forecast in our forward-looking statements.
We have discussed many of these factors in more detail elsewhere in this Report, including under the heading "COVID-19 Assessment" in Item 7 – "Management's Discussion and Analysis of Financial Condition and Results of Operations" of Part II of this Report. These factors are not necessarily all the factors that could affect us. Unpredictable or unanticipated factors we have not discussed in this Report could also have material adverse effects on actual results of matters that are the subject of our forward-looking statements. We do not intend to update or review any forward-looking statement or our description of important factors, whether as a result of new information, future events or otherwise, except as required by applicable laws.

Item 1A. RISK FACTORS
Industry Risks
We rely on U.S. Government contracts for a substantial percentage of our revenue, and some of those contracts are subject to continued appropriations by Congress and may be terminated or delayed if future funding is not made available. In addition, the U.S. Government may not renew or may seek to modify or terminate our existing contracts.
For the year ended December 31, 2020, U.S. Government contracts comprised approximately 77% of our total consolidated revenues. Government contracts are subject to various uncertainties, restrictions and regulations, including oversight audits, which could result in withholding or delaying payments to us, and termination or modification at the U.S. Government's convenience. In addition, some of our large, multi-year contracts with the U.S. Government are subject to annual funding determinations and the continuing availability of Congressional appropriations. Although multi-year operations may be planned in connection with major procurements, Congress generally appropriates funds on a fiscal-year basis even though a program may continue for several years. Consequently, programs often are only partially funded initially and additional funds are committed only as Congress makes further appropriations. When the U.S. Government does not complete its budget process before the end of its fiscal year on September 30, government operations typically are funded through a continuing resolution that authorizes agencies of the U.S. Government to continue to operate, but does not authorize new spending initiatives. When the U.S. Government operates under a continuing resolution or there are other disruptions in the funding process, delays can occur in the procurement of products and services. As a result, we are subject to ongoing uncertainties associated with U.S. Government budget constraints and other factors affecting government funding. The reduction or termination of funding, or
13

Table of Contents
changes in the timing of funding, for a U.S. Government program in which we provide products or services would result in a reduction or loss of anticipated future revenues attributable to that program and could have a negative impact on our financial condition, results of operations and cash flows.
In addition, our Nuclear Operations Group and Nuclear Services Group segments depend on U.S. Government funding, particularly funding levels at the DOE. Significant changes in the level of funding (for example, the annual budget of the DOE) or specifically mandated levels for individual programs that are important to our business could have an unfavorable impact on us. Any reduction in the level of U.S. Government funding, particularly at the DOE, may result in, among other things, a reduction in the number and scope of projects put out for bid by the U.S. Government or the curtailment of existing U.S. Government programs, either of which may result in a reduction in the number of contract award opportunities available to us, a reduction of activities at DOE sites and an increase in costs, including the costs of obtaining contract awards.
The U.S. Government typically can terminate or modify any of its contracts with us either for its convenience or if we default by failing to perform under the terms of the applicable contract. A termination arising out of our default could expose us to liability and have an adverse effect on our ability to compete for future contracts and orders. If any of our contracts reflected in backlog are terminated by the U.S. Government, our backlog would be reduced by the expected value of the remaining work under such contracts. In addition, on those contracts for which we are teamed with others and are not the prime contractor, the U.S. Government could terminate a prime contract under which we are a subcontractor, irrespective of the quality of our products and services as a subcontractor. Furthermore, certain of our U.S. Government contracts span one or more base years and multiple option years. The U.S. Government generally has the right not to exercise option periods and may not exercise an option period for various reasons.
We also have several significant contracts with the U.S. Government that are subject to periodic renewal and rebidding through a competitive process. If the U.S. Government fails to renew these contracts or modifies key terms, our results of operations and cash flows would be adversely affected.
As a result of these and other factors, the termination of one or more of our significant government contracts, our suspension from government contract work, the failure of the U.S. Government to renew our existing contracts or the disallowance of the payment of our contract costs could have a material adverse effect on our financial condition, results of operations and cash flows.
Federal budget sequestration and other delays or reductions in government spending could adversely impact government spending for the products and services we provide.
In August 2011, Congress enacted the Budget Control Act, which committed the U.S. Government to significantly reducing the federal deficit over ten years. The Budget Control Act established reductions in discretionary spending through 2021. If these spending reductions were not met, it called for substantial automatic spending cuts, or sequestration, split between defense and non-defense programs scheduled to start in March 2013 and continue over a nine-year period.
Federal government spending reductions, including through sequestration, could adversely impact U.S. Government programs for which we provide products or services. Additionally, while we believe many of our programs are well aligned with national defense and other strategic priorities, government spending on these programs can be subject to negative publicity, political factors and public scrutiny. The risk of future sequestration cuts is uncertain, and it is possible that spending cuts may be applied to U.S. Government programs across the board, regardless of how programs align with those priorities. There are many variables in how budget reductions could be implemented that will determine its specific impact; however, reductions in federal government spending and sequestration, as currently provided for under the Budget Control Act, could adversely impact programs in which we provide products or services. In addition, these cuts could adversely affect the viability of the suppliers and subcontractors under our programs. We may also be required to maintain operations of our joint ventures if the U.S. Government can no longer meet its debt obligations.
Demand for our products and services is vulnerable to economic downturns, the competitiveness of alternative energy sources and industry conditions.
Demand for our products and services has been, and we expect that demand will continue to be, subject to significant fluctuations due to a variety of factors beyond our control, including economic and industry conditions. These factors include, but are not limited to, inflation, geopolitical issues, the availability and cost of credit, the demand for and competitiveness of nuclear power with other energy sources, the cyclical nature of the power generation industry, low business and consumer confidence, high unemployment, energy conservation measures and decisions of utilities that operate nuclear power plants.

Table of Contents
Unfavorable economic conditions may lead customers to delay, curtail or cancel proposed or existing projects, which may decrease the overall demand for our products and services and adversely affect our results of operations.
Our customers may also find it more difficult to raise capital in the future due to limitations on the availability of credit, increases in interest rates and other factors affecting the federal, municipal and corporate credit markets. Additionally, our customers may demand more favorable pricing terms and find it increasingly difficult to timely pay invoices for our products and services, which would impact our future cash flows and liquidity. Inflation or significant changes in interest rates could reduce the demand for our products and services. Any inability to timely collect our invoices may lead to an increase in our accounts receivables and potentially to increased write-offs of uncollectable invoices. If the economy weakens, or customer spending declines, then our backlog, revenues, net income and overall financial condition could deteriorate.
Our future business prospects in Canada are dependent upon the continued operation of Canadian nuclear plants and refurbishment of the majority of the plants in Ontario to extend their operating lives. Unfavorable economic conditions, competition from other forms of power generation, increased competition for refurbishment contracts, changes in government policy or operational or project execution issues may lead nuclear plant operators in Canada to cease operations or delay, curtail or cancel proposed or existing life-extension projects, which may decrease the overall demand for our products and services in Canada and adversely affect our financial condition, results of operations and cash flows.
We are subject to risks associated with contractual pricing in our industries, including the risk that, if our actual costs exceed the costs we estimate on our fixed-price contracts, our profitability will decline and we may suffer losses.
We are engaged in a number of highly competitive industries and we have priced a number of our projects on a fixed-price basis. Our actual costs could exceed our projections, which may result in reduced profit or loss. We attempt to cover the increased costs of anticipated changes in labor, material and service costs of long-term contracts, either through estimates of cost increases, which are reflected in the original contract price, or through price escalation clauses. Despite these attempts, the cost and gross profit we realize on a fixed-price contract could vary materially from the estimated amounts because of supplier, contractor and subcontractor performance, execution issues, changes in job conditions, variations in labor and equipment productivity and increases in the cost of labor and raw materials, particularly steel, over the term of the contract.
These variations and the risks generally inherent in our industries may result in actual revenues or costs being different from those we originally estimated and may result in reduced profitability or losses on projects. Some of these risks include:
•difficulties encountered on our large-scale projects related to the procurement of materials or due to schedule disruptions, equipment performance failures, unforeseen site conditions, rejection clauses in customer contracts or other factors that may result in additional costs to us, reductions in revenue, claims or disputes;
•our inability to obtain compensation for additional work we perform or expenses we incur as a result of our customers providing deficient design, engineering information, equipment or materials;
•requirements to pay liquidated damages upon our failure to meet schedule or performance requirements of our contracts; and
•difficulties in engaging third-party subcontractors, equipment manufacturers or materials suppliers or failures by third-party subcontractors, equipment manufacturers or materials suppliers to perform could result in project delays and cause us to incur additional costs.
Operational Risks
Our business could be negatively impacted by security threats, including physical and cybersecurity threats, and other disruptions.
We face various security threats, including cyber threats, threats to the physical security of our facilities and infrastructure (including those that we manage and operate for our customers), and threats from terrorist acts, as well as the potential for business disruptions associated with these threats. Although we utilize a combination of tailored and industry standard security measures and technology to monitor and mitigate these threats, we cannot guarantee that these measures and technology will be sufficient to prevent security threats from materializing.
We have been, and will likely continue to be, subject to cyber-based attacks and other attempts to threaten our information technology systems, including attempts to gain unauthorized access to our proprietary and sensitive information and attacks from computer hackers, viruses, malicious code, internal threats and other security problems. As a U.S. Government contractor, we may be prone to a greater number of those threats than companies in other industries. These threats range from
15

Table of Contents
attacks common to most industries to more advanced and persistent threats from highly-organized adversaries targeting us because we are a U.S. Government contractor. We are required to maintain minimum security standards for handling information under our government contracts and failure to do so could result in termination of those contracts. From time to time, we experience system interruptions and delays; however, prior cyber-based attacks directed at us have not had a material adverse impact on our results of operations. Due to the evolving nature of these security threats, the impact of any future incident cannot be predicted. If we are unable to protect our proprietary and sensitive information, our customers could question the adequacy of our threat mitigation and detection processes and procedures, which could negatively impact our reputation and present and future business.
The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. Occurrence of any of these events could adversely affect our internal operations, the services we provide to customers, the value of our investment in research and development efforts and other intellectual property, our future financial results, our reputation or our stock price.
In addition, we maintain, replace and/or upgrade current financial, human resources and other information technology systems. These activities subject us to inherent costs and risks associated with replacing and updating these systems, including potential disruption of our internal control structure, substantial capital expenditures, demands on management time and other risks of delays or difficulties in transitioning to new systems or of integrating new systems into our current systems. Our systems implementations and upgrades may not result in productivity improvements at the levels anticipated, or at all. In addition, the implementation of new technology systems may cause disruptions in our business operations. Such disruptions and any other information technology system disruptions, and our ability to mitigate those disruptions, if not anticipated and appropriately mitigated, could have a material adverse effect on our business.
Actual or threatened public health epidemics or outbreaks, such as the recent outbreak of the COVID-19 illness, could have a material adverse effect on our business and results of operations.
Actual or threatened public health epidemics or outbreaks, such as the recent global outbreak of COVID-19, could have a material adverse effect on our business and results of operations. COVID-19, which has been declared by the World Health Organization to be a pandemic, has spread to over 200 countries, including every state in the United States. COVID-19 is impacting worldwide economic activity and has resulted in travel disruption, trade disruption and has affected companies’ operations around the world, including us. A public health epidemic, including COVID-19, poses the risk that we or our employees, contractors, suppliers, customers and other partners may be prevented from conducting business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities. If significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, facility closures or other restrictions in connection with the COVID-19 pandemic, our operations will likely be impacted. Although our U.S. and Canadian operations have to date been deemed "essential" by federal, state and local authorities and currently continue to operate, there can be no assurance that such authorities will not impose restrictions on the operations of our facilities as a result of the COVID-19 pandemic or that our facilities will continue to operate during the pandemic. If our operations or the operations of our customers or our suppliers are restricted, we may be unable to perform fully on our contracts and our costs may increase as a result of the COVID-19 outbreak. These cost increases may result in unfavorable changes in estimates which may not be fully recoverable or adequately covered by insurance or through government assistance programs such as the Coronavirus Aid, Relief and Economic Security Act in the U.S. (the "CARES Act") or the Canada Emergency Wage Subsidy (the "CEWS").
While it is not possible at this time to estimate the impact that COVID-19 could have on our business, the continued spread of COVID-19 and the measures taken by the governments of countries affected, as well as measures taken by state and local authorities in the United States, could disrupt the supply chain and the manufacture or shipment of our products and adversely impact our business, financial condition or results of operations. We have already experienced delays in the bidding and contracting process for our U.S. Government businesses, as well as the rescheduling of certain services that our Canadian nuclear service business provides during nuclear power plant outages. Additionally, we have noted a year over year decline in revenues in our medical radioisotopes and radiopharmaceuticals business due to a decrease in demand for elective diagnostic procedures. More widespread or further delays could have a material adverse impact on our results of operations.
The COVID-19 outbreak and mitigation measures may also have an adverse impact on global economic conditions, which could have an adverse effect on our business. The extent to which the COVID-19 outbreak impacts our business will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact.

Additionally, the Canadian Government may review and audit the wage subsidies received under the CEWS and could disallow benefits for which we have applied. If these subsidies are reduced, disallowed or repealed due to changes in law or determination by the Canadian Government, it could have a material adverse effect on our financial condition, results of operations and cash flows. Moreover, there may be public scrutiny of government aid beneficiaries and as a result, our reputation could be harmed by participating in the CEWS.
We rely on intellectual property law and confidentiality agreements to protect our intellectual property. We also rely on intellectual property we license from third parties. Our failure to protect our intellectual property rights, our infringement of third party intellectual property or our inability to obtain or renew licenses to use intellectual property of third parties, could adversely affect our business.
Our success depends, in part, on our ability to protect our proprietary information and other intellectual property. Our intellectual property could be stolen, challenged, invalidated, circumvented or rendered unenforceable. In addition, effective intellectual property protection may be limited or unavailable in some foreign countries where we operate.
Our failure to protect our intellectual property rights may result in the loss of valuable technologies or adversely affect our competitive business position. We rely significantly on proprietary technology, information, processes and know-how that are not subject to patent or copyright protection. We seek to protect this information through trade secret or confidentiality agreements with our employees, consultants, subcontractors or other parties, as well as through other security measures. These agreements and security measures may be inadequate to deter or prevent misappropriation of our confidential information. In the event of an infringement of our intellectual property rights, a breach of a confidentiality agreement or divulgence of proprietary information, we may not have adequate legal remedies to protect our intellectual property. In addition, third parties may allege that we have infringed their intellectual property rights, which could result in litigation. Litigation to protect, defend or determine the scope of intellectual property rights, even if ultimately successful, could be costly and could divert management's attention away from other aspects of our business. In addition, our trade secrets may otherwise become known or be independently developed by competitors.
In some instances, we have augmented our technology base by licensing the proprietary intellectual property of third parties. In the future, we may not be able to obtain necessary licenses on commercially reasonable terms, which could have a material adverse effect on our operations.
Our operations are subject to operating risks, which could expose us to potentially significant professional liability, product liability, warranty and other claims. Our insurance coverage may be inadequate to cover all of our significant risks or our insurers may deny coverage of material losses we incur, which could adversely affect our profitability and overall financial condition.
We operate large manufacturing facilities and perform services in large commercial power plants where accidents or system failures can have significant consequences. Risks inherent in our operations include:
•accidents resulting in injury or the loss of life or property;
•environmental or toxic tort claims, including delayed manifestation claims for personal injury or loss of life;
•pollution or other environmental mishaps;
•adverse weather conditions;
•mechanical or design failures;
•property losses;
•business interruption due to political action in foreign countries or other reasons; and
•labor stoppages.
Any accident or failure at a site where we have provided products or services could result in significant professional liability, product liability, warranty and other claims against us, regardless of whether our products or services caused the incident. We have been, and in the future we may be, named as defendants in lawsuits asserting large claims as a result of litigation arising from events such as those listed above.
We endeavor to identify and obtain, in established markets, insurance agreements to cover significant risks and liabilities. Insurance against some of the risks inherent in our operations is either unavailable or available only at rates or on terms that we
17

Table of Contents
consider uneconomical. Also, catastrophic events customarily result in decreased coverage limits, more limited coverage, additional exclusions in coverage, increased premium costs and increased deductibles and self-insured retentions. Risks that we have frequently found difficult to cost-effectively insure against include, but are not limited to, business interruption, property losses from wind, flood and earthquake events, nuclear hazards and war, pollution liability, liabilities related to occupational health exposures (including asbestos), professional liability/errors and omissions coverage, the failure, misuse or unavailability of our information systems, the failure of security measures designed to protect our information systems from security breaches, and liability related to risk of loss of our work in progress and customer-owned materials in our care, custody and control. Depending on competitive conditions and other factors, we endeavor to obtain contractual protection against certain uninsured risks from our customers. When obtained, such contractual indemnification protection may not be as broad as we desire or may not be supported by adequate insurance maintained by the customer. Such insurance or contractual indemnity protection may not be sufficient or effective under all circumstances or against all hazards to which we may be subject. A successful claim for which we are not insured or for which we are underinsured could have a material adverse effect on us. Additionally, disputes with insurance carriers over coverage may affect the timing of cash flows and, if litigation with the carrier becomes necessary, an outcome unfavorable to us may have a material adverse effect on our results of operations.
We are also involved in management and operating activities for the U.S. Government. These activities involve, among other things, handling nuclear devices and their components for the U.S. Government. Most insurable liabilities arising from these sites are not protected in our corporate insurance program. Instead, we rely on government contractual agreements, some insurance purchased specifically for the sites and certain specialized self-insurance programs funded by the U.S. Government. The U.S. Government has historically fulfilled its contractual agreement to reimburse for insurable claims, and we expect it to continue this process. However, it should be noted that, in most situations, the U.S. Government is contractually obligated to pay subject to the availability of authorized government funds. The reimbursement obligation of the U.S. Government is also conditional, and provisions of the relevant contract or applicable law may preclude reimbursement.
We have a captive insurance company subsidiary that provides us with various insurance coverages. Claims, as a result of our operations, could adversely impact the ability of our captive insurance company subsidiary to respond to all claims presented.
Although we have product liability insurance coverage, with policy limits that we believe are customary for the medical radioisotope industry, such coverage may not be adequate, requiring that we pay judgments or settlement amounts in excess of policy limits. We may not be able to maintain insurance coverage at adequate levels. Any product liability claims could be costly to defend, time-consuming and result in adverse judgments, which could result in a material adverse effect on our business, reputation and results.
Additionally, upon the February 22, 2006 effectiveness of the settlement relating to the Chapter 11 proceedings involving several of our former subsidiaries, most of our subsidiaries contributed substantial insurance rights providing coverage for, among other things, asbestos and other personal injury claims, to an asbestos personal injury trust. With the contribution of these insurance rights to the asbestos personal injury trust, we may have underinsured or uninsured exposure for non-derivative asbestos claims or other personal injury or other claims that would have been insured under these coverages had the insurance rights not been contributed to the asbestos personal injury trust. In conjunction with the spin-off, claims and liabilities associated with the asbestos personal injury, property damage and indirect property damage claims mentioned above have been expressly assumed by BWE pursuant to the master separation agreement between us and BWE.
Negotiations with labor unions and possible work stoppages and other labor problems could divert management's attention and disrupt operations. In addition, new collective bargaining agreements or amendments to agreements could increase our labor costs and operating expenses.
A significant number of our employees are members of labor unions. If we are unable to negotiate acceptable new contracts with our unions from time to time, we could experience strikes or other work stoppages by the affected employees. If any such strikes or other work stoppages were to occur, we could experience a significant disruption of operations. In addition, negotiations with unions could divert management attention. New union contracts could result in increased operating costs, as a result of higher wages or benefit expenses, for both union and nonunion employees. If nonunion employees were to unionize, we would experience higher ongoing labor costs.
We rely on single-source suppliers, which could, under certain circumstances, adversely affect our revenues and operating results.
We rely on several single-source suppliers for materials used in our products in our Nuclear Operations Group segment. If the supply of a single-sourced material is delayed or ceases, we may not be able to produce the related product in a timely
18

Table of Contents
manner or in sufficient quantities, if at all, which could adversely affect our revenues and operating results. In addition, a single-source supplier of a key component could potentially exert significant bargaining power over price, quality, warranty claims or other terms relating to the single-sourced materials, which could have a material adverse effect on our financial condition, results of operations and cash flows.
Maintaining adequate bonding and letter of credit capacity is necessary for us to successfully bid on and win various contracts.
In line with industry practice, we are often required to post standby letters of credit and surety bonds to support contractual obligations to customers as well as other obligations. These letters of credit and bonds generally indemnify customers should we fail to perform our obligations under the applicable contracts. If a letter of credit or bond is required for a particular project and we are unable to obtain it due to insufficient liquidity or other reasons, we will not be able to pursue that project. We utilize bonding facilities, but, as is typically the case, the issuance of bonds under each of those facilities is at the surety's sole discretion. In addition, we have capacity limits under our credit facility for letters of credit. Moreover, due to events that affect the insurance and bonding and credit markets generally, bonding and letters of credit may be more difficult to obtain in the future or may only be available at significant additional cost. There can be no assurance that letters of credit or bonds will continue to be available to us on reasonable terms. Our inability to obtain adequate letters of credit and bonding and, as a result, to bid on new work could have a material adverse effect on our business, financial condition and results of operations. As of December 31, 2020, we had $68.3 million in letters of credit and $73.7 million in surety bonds outstanding.
Our business strategy includes acquisitions and strategic investments to support our growth, which can create certain risks and uncertainties.
We intend to pursue growth through the acquisition of, or strategic investments in, businesses or assets that we believe will enable us to strengthen our existing businesses and expand into adjacent industries. We may be unable to execute this growth strategy if we cannot identify suitable businesses or assets, reach agreement on potential strategic acquisitions on acceptable terms or for other reasons.
Acquisitions may be funded by the issuance of additional equity or debt financing, which may not be available on attractive terms. Our ability to secure such financing will depend in part on prevailing capital market conditions, as well as conditions in our business and operating results. Moreover, to the extent an acquisition transaction financed by non-equity consideration results in goodwill, it will reduce our tangible net worth, which might have an adverse effect on potential credit and bonding capacity.
Additionally, an acquisition may bring us into businesses we have not previously conducted and expose us to additional business risks that are different than those we have historically experienced.
Our business strategy also includes development and commercialization of new technologies to support our growth, which requires significant investment and involves various risks and uncertainties. These new technologies may not achieve desired commercial or financial results.
Our future growth will depend on our ability to continue to innovate by developing and commercializing new product and service offerings. Investments in new technologies involve varying degrees of uncertainties and risk. Commercial success depends on many factors, including the levels of innovation, the development costs and the availability of capital resources to fund those costs, the levels of competition from others developing similar or other competing technologies, our ability to obtain or maintain government permits or certifications, the effectiveness of production, distribution and marketing efforts, market acceptance and the costs to customers to deploy and provide support for the new technologies. We may not achieve significant revenue from new product and service investments for a number of years, if at all. Additionally, there can be no assurance that the current technologies that our businesses rely upon will remain competitive, or that competing technologies will not disrupt our business. Moreover, new products and services may not be profitable, and, even if they are profitable, our operating margins from new products and services may not be as high as the margins we have experienced historically. Lastly, new technologies may not be patentable and, as a result, we may face increased competition.
Among our opportunities involving new technologies, we are developing new medical radioisotope technology. The costs to develop and commercialize this technology require a substantial amount of investment over a period of years, and commercialization of this technology also requires authorizations from government agencies, including the U.S. Food and Drug Administration ("FDA"), Health Canada and the CNSC. There can be no assurance that we will be successful in addressing all of the technological challenges to developing and commercializing this technology or in obtaining the required authorizations from the FDA, Health Canada or the CNSC. In addition, commercialization of the medical radioisotope technology could
19

Table of Contents
subject us to product liability claims. The potential also exists for competitors to emerge with alternative technologies. We can provide no assurance that those competitors will not develop and commercialize similar or superior technologies sooner than we can or at a significant cost or price advantage.
We conduct a portion of our operations through joint venture entities, over which we may have limited ability to influence.
We currently have equity interests in several joint ventures and may enter into additional joint venture arrangements in the future. Our influence over some of these entities may be limited. Even in those joint ventures over which we do exercise significant influence, we are often required to consider the interests of our joint venture partners in connection with major decisions concerning the operations of the joint ventures. In any case, differences in views among the joint venture participants may result in delayed decisions or disputes. We also cannot control the actions of our joint venture partners. We sometimes have joint and several liabilities with our joint venture partners under the applicable contracts for joint venture projects and we cannot be certain that our partners will be able to satisfy any potential liability that could arise. These factors could potentially harm the business and operations of a joint venture and, in turn, our business and operations.
Operating through joint ventures in which we are minority holders results in us having limited control over many decisions made with respect to projects and internal controls relating to projects. These joint ventures may not be subject to the same requirements regarding internal controls and internal control over financial reporting that we follow. As a result, internal control problems may arise with respect to the joint ventures that could adversely affect our ability to respond to requests or contractual obligations to customers or to meet the internal control requirements to which we are otherwise subject.
In addition, our arrangements involving joint ventures may restrict us from gaining access to the cash flows or assets of these entities. In some cases, our joint ventures have governmentally imposed restrictions on their abilities to transfer funds to us.
If our co-venturers fail to perform their contractual obligations on a project or if we fail to coordinate effectively with our co-venturers, we could be exposed to legal liability, loss of reputation and reduced profit on the project.
We often perform projects jointly with third parties. For example, we enter into contractual arrangements to bid for and perform jointly on large projects. Success on these joint projects depends in part on whether our co-venturers fulfill their contractual obligations satisfactorily. If any one or more of these third parties fail to perform their contractual obligations satisfactorily, we may be required to make additional investments and provide added services in order to compensate for that failure. If we are unable to adequately address any such performance issues, then our customer may exercise its right to terminate a joint project, exposing us to legal liability, loss of reputation and reduced profit.
Our collaborative arrangements also involve risks that participating parties may disagree on business decisions and strategies. These disagreements could result in delays, additional costs and risks of litigation. Our inability to successfully maintain existing collaborative relationships or enter into new collaborative arrangements could have a material adverse effect on our results of operations.
Accounting and Financial Reporting Risks
We recognize a large portion of our revenue on an over time basis which could result in volatility in our results of operations.
We generally recognize revenues and profits under our long-term contracts on an over time basis. Accordingly, we review contract price and cost estimates regularly as the work progresses and reflect adjustments proportionate to our progress made towards completion in income in the period when we revise those estimates. To the extent these adjustments result in a reduction or an elimination of previously reported profits with respect to a project, we would recognize a charge against current earnings, which could be material. Our current estimates of our contract costs and the profitability of our long-term projects, although reasonably reliable when made, could change as a result of the uncertainties associated with these types of contracts, and if adjustments to overall contract costs are significant, the reductions or reversals of previously recorded revenue and profits could be material in future periods.
20

Table of Contents
Our backlog is subject to unexpected adjustments and cancellations and may not be a reliable indicator of future revenues or earnings.
There can be no assurance that the revenues projected in our backlog will be realized or, if realized, will result in profits. Because of project cancellations or changes in project scope and schedule, we cannot predict with certainty when or if backlog will be performed. In addition, even where a project proceeds as scheduled, it is possible that contracted parties may default and fail to pay amounts owed to us or poor project performance could increase the cost associated with a project. Delays, suspensions, cancellations, payment defaults, scope changes and poor project execution could materially reduce or eliminate the revenues and profits that we actually realize from projects in backlog.
Reductions in our backlog due to cancellation or modification by a customer or for other reasons may adversely affect, potentially to a material extent, the revenues and earnings we actually receive from contracts included in our backlog. Many of the contracts in our backlog provide for cancellation fees in the event customers cancel projects. These cancellation fees usually provide for reimbursement of our out-of-pocket costs, revenues for work performed prior to cancellation and a varying percentage of the profits we would have realized had the contract been completed. However, we typically have no contractual right upon cancellation to the total revenues reflected in our backlog. Projects may remain in our backlog for extended periods of time. If we experience significant project terminations, suspensions or scope adjustments to contracts reflected in our backlog, our financial condition, results of operations and cash flows may be adversely impacted.
Pension and medical expenses associated with our retirement benefit plans may fluctuate significantly depending on changes in actuarial assumptions, future market performance of plan assets, future trends in health care costs and legislative or other regulatory actions.
A substantial portion of our current and retired employee population is covered by pension and postretirement benefit plans, the costs and funding requirements of which depend on our various assumptions, including estimates of rates of return on benefit-related assets, discount rates for future payment obligations, rates of future cost growth, mortality assumptions and trends for future costs. Service accruals for salaried participants ceased as of December 31, 2015. Variances from these estimates could have a material adverse effect on us. In addition, our policy to recognize these variances annually through mark to market accounting could result in volatility in our results of operations, which could be material. As of December 31, 2020, we had underfunded defined benefit pension and postretirement benefit plans with obligations totaling approximately $(174.5) million. A substantial portion of our postretirement benefit plan costs are recoverable on our U.S. Government contracts. See Note 7 to our consolidated financial statements included in this Report for additional information regarding our pension and postretirement benefit plan obligations.
Legal, Regulatory and Compliance Risks
We are involved in a number of legal proceedings. We cannot predict the outcome of litigation and other contingencies with certainty.
Our business may be adversely affected by the outcome of legal proceedings, disputes and other contingencies that cannot be predicted with certainty. As required by GAAP, we estimate loss contingencies and establish reserves based on our assessment of contingencies where liability is deemed probable and reasonably estimable in light of the facts and circumstances known to us at a particular point in time. Subsequent developments in legal proceedings may affect our assessment and estimates of the loss contingency recorded as a liability or as a reserve against assets in our financial statements. For a description of current legal proceedings, see "Note 10 – Commitments and Contingencies" to our consolidated financial statements included in this Report.
If we fail to comply with government procurement laws and regulations, we could lose business and be liable for various penalties or sanctions.
We must comply with laws and regulations relating to the formation, administration, and performance of U.S. Government contracts. These laws and regulations include the FAR, Defense Federal Acquisition Regulations, the Truth in Negotiations Act, CAS, and laws, regulations, and orders restricting the use and dissemination of classified information under the U.S. export control laws and the export of certain products and technical information. Certain government contracts provide audit rights by government agencies, including with respect to performance, costs, internal controls and compliance with applicable laws and regulations. In complying with these laws and regulations, we may incur significant costs, and non-compliance may result in the imposition of fines and penalties, including contractual damages. If we fail to comply with these laws and regulations or if a government audit, review, or investigation uncovers improper or illegal activities, we may be subject to civil penalties, criminal penalties, or administrative sanctions, including suspension or debarment from contracting
21

with the U.S. Government. Our reputation could suffer harm if allegations of impropriety were made or found against us, which could adversely affect our operating performance and may result in additional expenses and possible loss of revenue.
Employee, agent or partner misconduct or our overall failure to comply with laws, regulations or government contracts could weaken our ability to win contracts, lead to the suspension of our operations and result in reduced revenues and profits.
Misconduct, fraud, or other improper activities by one or more of our employees, agents or partners, as well as our failure to comply with applicable laws and regulations, could have a significant negative impact on our business and reputation. Such misconduct could include the failure to comply with government procurement regulations, regulations regarding the protection of classified and other information, regulations regarding the pricing of labor and other costs in government contracts, regulations on lobbying or similar activities, regulations pertaining to the internal controls over financial reporting and various other applicable laws or regulations. For example, we regularly provide services that may be highly sensitive or that are related to critical national security matters; if a security breach were to occur, our ability to procure future government contracts could be severely limited. The precautions we take to prevent and detect these activities may not be effective, and we could face unknown risks or losses.
We are routinely audited and reviewed by the U.S. Government and its agencies. These agencies review our performance under our contracts, our cost structure and our compliance with applicable laws, regulations and standards, as well as the adequacy of, and our compliance with, our internal control systems and policies. Systems that are subject to review include our purchasing systems, billing systems, property management and control systems, cost estimating systems, compensation systems and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. If an audit or review uncovers improper or illegal activities, we could be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines, loss of security clearance and suspension or debarment from contracting with the U.S. Government. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us.
Our nuclear operations subject us to various environmental, regulatory, financial and other risks.
Our operations in designing, engineering, manufacturing, supplying, constructing and maintaining nuclear fuel and nuclear power equipment and components subject us to various risks, including:
•potential liabilities relating to harmful effects on the environment and human health resulting from nuclear operations and the storage, handling and disposal of radioactive materials;
•unplanned expenditures relating to maintenance, operation, security, defects, upgrades and repairs required by the NRC and other government agencies;
•limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with nuclear operations; and
•potential liabilities arising out of a nuclear, radiological or criticality incident, whether or not it is within our control.
Our nuclear operations are subject to various safety-related requirements imposed by the U.S. Government, the DOE and the NRC. In the event of non-compliance, these agencies might increase regulatory oversight, impose fines or shut down our operations, depending upon the assessment of the severity of the situation. Revised security and safety requirements promulgated by these agencies could necessitate substantial capital and other expenditures. In addition, we must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. Government contracts. Government contract laws and regulations affect how we do business with our customers and, in some instances, impose added costs on our business. A violation of specific laws and regulations could result in the imposition of fines and penalties or the termination of our contracts or debarment from bidding on contracts.
Limitations or modifications to indemnification regulations of the U.S. or foreign countries could adversely affect our business.
The Price-Anderson Act partially indemnifies the nuclear industry against liability arising from nuclear incidents in the U.S., while ensuring compensation for the general public. The Price-Anderson Act comprehensively regulates the manufacture, use and storage of radioactive materials, while promoting the nuclear industry by offering broad indemnification to commercial nuclear power plant operators and DOE contractors. Because we provide nuclear fabrication and other services to the DOE relating to its nuclear devices, facilities and other programs and the nuclear power industry in the ongoing maintenance and
22

Table of Contents
modifications of its nuclear power plants, including the manufacture of equipment and other components for use in such nuclear power plants, we may be entitled to some of the indemnification protections under the Price-Anderson Act against liability arising from nuclear incidents in the U.S. The indemnification authority under the Price-Anderson Act was extended through December 2025 by the Energy Policy Act of 2005. We also provide nuclear fabrication and other services to the nuclear power industry in Canada and other countries. Canada's NLCA generally conforms to international conventions and is conceptually similar to the Price-Anderson Act in the U.S. Accordingly, indemnification protections and the possibility of exclusions under Canada's NLCA are similar to those under the Price-Anderson Act in the U.S.
The Price-Anderson Act and Canada's NLCA indemnification provisions may not apply to all liabilities that we might incur while performing services as a contractor for the DOE and the nuclear power industry. If an incident or evacuation is not covered under the Price-Anderson Act's or Canada's NLCA's indemnification provisions, we could be held liable for damages, regardless of fault, which could have an adverse effect on our results of operations and financial condition. In connection with the international transportation of toxic, hazardous and radioactive materials, it is possible for a claim to be asserted that may not fall within the indemnification provided by the Price-Anderson Act or Canada's NLCA. If such indemnification authority is not applicable in the future, our business could be adversely affected if the owners and operators of nuclear power plants fail to retain our services in the absence of commercially adequate insurance and indemnification.
Moreover, because we manufacture nuclear components for the U.S. Government's defense program, we may be entitled to some of the indemnification protections afforded by Public Law 85-804 for certain of our nuclear operations risks. Public Law 85-804 authorizes certain agencies of the U.S. Government, such as the DOE and the U.S. Department of Defense, to indemnify their contractors against unusually hazardous or nuclear risks when such action would facilitate the national defense. However, because the indemnification protections afforded by Public Law 85-804 are granted on a discretionary basis, situations could arise where the U.S. Government elects not to offer such protections. In such situations, our business could be adversely affected by either our inability to obtain commercially adequate insurance or indemnification or our refusal to pursue such operations in the absence of such protections.
Our operations involve the handling, transportation and disposal of radioactive and hazardous materials, and environmental laws and regulations and civil liability for contamination of the environment or related personal injuries may result in increases in our operating costs and capital expenditures and decreases in our earnings and cash flows.
Our operations involve the handling, transportation and disposal of radioactive and hazardous materials, including nuclear devices and their components. Failure to properly handle these materials could pose a health risk to humans or wildlife and could cause personal injury and property damage (including environmental contamination). If an accident were to occur, its severity could be significantly affected by the volume of the materials and the speed of corrective action taken by emergency response personnel, as well as other factors beyond our control, such as weather and wind conditions. Actions taken in response to an accident could result in significant costs.
Governmental requirements relating to the protection of the environment, including solid waste management, air quality, water quality, the decontamination and decommissioning of nuclear manufacturing and processing facilities and cleanup of contaminated sites, have had a substantial impact on our operations. These requirements are complex and subject to frequent change. In some cases, they can impose liability for the entire cost of cleanup on any responsible party without regard to negligence or fault and impose liability on us for the conduct of others or conditions others have caused, or for our acts that complied with all applicable requirements when we performed them. Our compliance with amended, new or more stringent requirements, stricter interpretations of existing requirements or the future discovery of contamination may require us to make material expenditures or subject us to liabilities that we currently do not anticipate. Such expenditures and liabilities may adversely affect our business, financial condition, results of operations and cash flows. In addition, some of our operations and the operations of predecessor owners of some of our properties have exposed us to civil claims by third parties for liability resulting from alleged contamination of the environment or personal injuries caused by releases of hazardous substances into the environment. See Item 1, "Business - Governmental Regulations and Environmental Matters."
In our contracts, we seek to protect ourselves from liability associated with accidents, but there can be no assurance that such contractual limitations on liability will be effective in all cases or that our or our customers' insurance will cover all the liabilities we have assumed under those contracts. The costs of defending against a claim arising out of a nuclear incident or precautionary evacuation, and any damages awarded as a result of such a claim, could adversely affect our results of operations and financial condition.
We maintain insurance coverage as part of our overall risk management strategy and due to requirements to maintain specific coverage in our financing agreements and in many of our contracts. These policies do not protect us against all

liabilities associated with accidents or for unrelated claims. In addition, comparable insurance may not continue to be available to us in the future at acceptable prices, or at all.
Our business requires us to obtain, and to comply with, national, state and local government permits and approvals.
Our business is required to obtain, and to comply with, national, state and local government permits and approvals. Any of these permits or approvals may be subject to denial, revocation or modification under various circumstances. Failure to obtain or comply with the conditions of permits or approvals may adversely affect our operations by temporarily suspending our activities or curtailing our work and may subject us to penalties and other sanctions. Although existing licenses are routinely renewed by various regulators, renewal could be denied or jeopardized by various factors, including:
•failure to provide adequate financial assurance for decommissioning or closure;
•failure to comply with environmental and safety laws and regulations or permit conditions;
•local community, political or other opposition;
•executive action; and
•legislative action.
As a result of our acquisition of the MI business in 2018, we are also subject to regulatory oversight by the FDA and Health Canada. The commercialization of our medical radioisotope technology will require the review and approval of these and other government agencies. Any delay or denial of such approvals could have a material adverse effect on our MI business.
In addition, if new legislation or regulations are enacted or implemented, or if existing laws or regulations are amended or are interpreted or enforced differently, we may be required to obtain additional operating permits or approvals. Our inability to obtain, and to comply with, the permits and approvals required for our business could have a material adverse effect on us.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Statements we make in the following discussion, which express a belief, expectation or intention, as well as those that are not historical fact, are forward-looking statements that are subject to risks, uncertainties and assumptions. Our actual results, performance or achievements, or industry results, could differ materially from those we express in the following discussion as a result of a variety of factors, including the risks and uncertainties we have referred to under the headings "Cautionary Statement Concerning Forward-Looking Statements" and "Risk Factors" in Items 1 and 1A of Part I of this Report.
GENERAL
We are a leading supplier of nuclear components and fuel to the U.S. Government; provide technical, management and site services to support governments in the operation of complex facilities and environmental remediation activities; supply precision manufactured components, nuclear fuel and services for the commercial nuclear power industry; supply critical medical radioisotopes and radiopharmaceuticals; and develop nuclear technologies for a variety of applications, including medical radioisotopes, advanced nuclear power sources and advanced nuclear reactors. In general, we operate in capital-intensive industries and rely on large contracts for a substantial amount of our revenues. We operate in three reportable segments: Nuclear Operations Group, Nuclear Power Group and Nuclear Services Group. We are currently exploring growth strategies across our segments through strategic investments and acquisitions to expand and complement our existing businesses. We would expect to fund these opportunities with cash generated from operations or by raising additional capital through debt, equity or some combination thereof.
Outlook
Nuclear Operations Group
We expect the backlog of our Nuclear Operations Group segment of approximately $3,659 million at December 31, 2020 to produce revenues of approximately $1,221 million in 2021, not including any change orders or new contracts that may be awarded during the year.
The revenues of our Nuclear Operations Group segment are largely a function of defense spending by the U.S. Government. As a supplier of major nuclear components for certain U.S. Government programs, we are a significant participant in the defense industry and have not been negatively impacted by sequestration or federal budget reductions to date. We believe many of our programs are well-aligned with national defense and other strategic priorities as we supply high-end equipment for submarines and aircraft carriers for the U.S. Navy. However, it is possible that reductions in federal government spending and sequestration could have an adverse impact on the operating results and cash flows of this segment in the future.
We expect that orders for nuclear components will continue to be a significant part of backlog for the foreseeable future. In addition, the U.S. Navy issued its fiscal year 2022 long-range shipbuilding plan in December 2020, which maintains recommendations made in its fiscal year 2020 long-range shipbuilding plan (released in September 2019) to increase the size of its fleet of ships to include additional submarines and aircraft carriers beyond the number disclosed prior to September 2019. While the new Administration may make further changes with its fiscal year 2022 budget submission, we have made additional capital expenditures and investments in personnel to meet this anticipated growth in demand and we expect to continue making such expenditures and investments.
Nuclear Power Group
We expect the backlog of our Nuclear Power Group segment of approximately $726 million at December 31, 2020 to produce revenues of approximately $307 million in 2021, not including any change orders or new contracts that may be awarded during the year. The revenues in this segment primarily depend on the demand and competitiveness of nuclear energy. The activity of this segment depends on the timing of maintenance and refueling outages, the cyclical nature of capital expenditures and major refurbishment and plant life extension projects, as well as the demand for nuclear fuel and fuel handling equipment primarily in the Canadian market, which could cause variability in our financial results.
Our acquisition of the MI business in July 2018 expanded our Nuclear Power Group segment's offerings to include medical radioisotope products. The MI business will be the platform from which we plan to launch our Molybdenum-99 product line and a number of future radioisotope-based imaging, diagnostic and therapeutic products.

Table of Contents
Nuclear Services Group
A significant portion of this segment's operations is conducted through joint ventures, which typically earn fees, and we account for them following the equity method of accounting. See Note 4 to our consolidated financial statements included in this Report for financial information on our equity method investments. As a result, this segment reports minimal backlog and revenues.
Given our specialized capabilities of full life-cycle management of special materials, facilities and technologies, we believe our Nuclear Services Group segment is well-positioned to participate in the continuing cleanup, operation and management of critical government-owned nuclear sites, laboratories and manufacturing complexes maintained by the DOE, NASA and other federal agencies. However, it is possible that reductions in federal government spending and sequestration could have an adverse impact on the operating results and cash flows of this segment in the future.
This segment also specializes in the development of advanced technologies. The nature, timing and duration of any related contracts are dependent on the demand and funding availability for such technologies.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Our financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are affected by management's application of accounting policies. We believe the following are our most critical accounting policies that we apply in the preparation of our financial statements. These policies require our most difficult, subjective and complex judgments, often as a result of the need to make estimates of matters that are inherently uncertain.
Contracts and Revenue Recognition. We determine the appropriate accounting method for each of our long-term contracts before work on the project begins. We generally recognize contract revenues and related costs over time for individual performance obligations based on a cost-to-cost method in accordance with FASB Topic Revenue from Contracts with Customers. We recognize estimated contract revenue and resulting income based on the measurement of the extent of progress toward completion as a percentage of the total project. Certain costs may be excluded from the cost-to-cost method of measuring progress, such as significant costs for uninstalled materials, if such costs do not depict our performance in transferring control of goods or services to the customer. We review contract price and cost estimates periodically as the work progresses and reflect adjustments proportionate to the percentage-of-completion in income in the period when those estimates are revised. Certain of our contracts recognize revenue at a point in time, and revenue on these contracts is recognized when control transfers to the customer. The majority of our revenue that is recognized at a point in time is related to parts and certain medical radioisotopes and radiopharmaceuticals in our Nuclear Power Group segment. For all contracts, if a current estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full when determined. It is possible that current estimates could materially change for various reasons, including, but not limited to, fluctuations in forecasted labor productivity or steel and other raw material prices. We routinely review estimates related to our contracts, and revisions to profitability are reflected in the quarterly and annual earnings we report. In the years ended December 31, 2020, 2019 and 2018, we recognized net favorable changes in estimates related to long-term contracts that increased operating income by approximately $42.8 million, $71.6 million and $46.3 million, respectively.
Although we continually strive to improve our ability to estimate our contract costs and profitability, adjustments to overall contract costs due to unforeseen events could be significant in future periods. We recognize contract change orders or changes in scope of work in contract revenues, to the extent of costs incurred, when we believe collection is probable and can be reasonably estimated. We recognize income from claims when formally agreed with the customer. We regularly assess the collectability of contract revenues and receivables from customers.
Pension Plans and Postretirement Benefits. We utilize actuarial and other assumptions in calculating the cost and benefit obligations of our pension and postretirement benefits. The assumptions utilized in the determination of our benefit cost and obligations include assumptions regarding discount rates, expected returns on plan assets, mortality and health care cost trends. The assumptions utilized represent our best estimates based on historical experience and other factors.
We calculate the majority of our pension costs under both financial accounting standards ("FAS") in accordance with GAAP and CAS in accordance with the FAR. We have prepared our consolidated financial statements and segment reporting disclosures utilizing pension costs calculated under FAS. Pension costs calculated under CAS are utilized as the basis for recovery of pension costs on our U.S. Government contracts. For the years ended December 31, 2020, 2019 and 2018, our CAS pension costs attributed to U.S. Government contracts totaled $43.6 million, $46.7 million and $44.0 million, respectively. The
29

Table of Contents
amount of recoverable CAS pension costs recognized as revenue on an annual basis may differ from the amounts noted above. See further discussion of our accounting for contracts and revenue recognition above and in Note 1 to our consolidated financial statements included in this Report.
Actual experience that differs from these assumptions or future changes in assumptions will affect our recognized benefit obligations and related costs. We immediately recognize net actuarial gains and losses in earnings in the fourth quarter as a component of net periodic benefit cost. Net actuarial gains and losses occur when actual experience differs from any of the various assumptions used to value our pension and postretirement benefit plans or when assumptions, which are revisited annually through our update of our actuarial valuations, change due to current market conditions or underlying demographic changes. The primary factors contributing to net actuarial gains and losses are changes in the discount rate used to value the obligations as of the measurement date each year, the difference between the actual return on plan assets and the expected return on plan assets and changes in health care cost trends. The effect of changes in the discount rate and expected rate of return on plan assets assumptions in combination with the actual return on plan assets can result in significant changes in our estimated pension and postretirement benefit cost and our consolidated financial condition.
The following sensitivity analysis shows the impact of a 25 basis point change in the assumed discount rate, return on assets and health care cost trend rate on our FAS pension and postretirement benefit plan obligations and expense for the year ended December 31, 2020:

(1)Excludes effect of annual mark to market adjustment.
Goodwill and Intangible Assets. Each year, we evaluate goodwill at each reporting unit to assess recoverability, and impairments, if any, are recognized in earnings. We perform a qualitative analysis when we believe that there is sufficient excess fair value over carrying value based on our most recent quantitative assessment, adjusted for relevant facts and circumstances that could affect fair value. Deterioration in macroeconomic, industry and market conditions, cost factors, overall financial performance, share price decline or entity and reporting unit specific events could cause us to believe a qualitative test is no longer appropriate.
When we determine that it is appropriate to test goodwill for impairment utilizing a quantitative test, we compare the fair value of a reporting unit to its carrying amount, including goodwill. We utilize both the income and market valuation approaches to provide inputs into the estimate of the fair value of our reporting units, which would be considered by market participants.
Under the income valuation approach, we employ a discounted cash flow model to estimate the fair value of each reporting unit. This model requires the use of significant estimates and assumptions regarding future revenues, costs, margins, capital expenditures, changes in working capital, terminal year growth rate and cost of capital. Our cash flow models are based on our forecasted results for the applicable reporting units. Actual results could differ materially from our projections. Some assumptions, such as future revenues, costs and changes in working capital are company driven and could be affected by a loss of one or more significant contracts or customers, failure to control costs on certain contracts, a decline in U.S. Government

funding or a decline in demand based on changing economic or regulatory conditions. Changes in external market conditions may affect certain other assumptions, such as the cost of capital. Market conditions can be volatile and are outside of our control.
Under the market valuation approach, we employ the guideline publicly traded company method, which indicates the fair value of the equity of each reporting unit by comparing it to publicly traded companies in similar lines of business. After identifying and selecting guideline companies, we analyze their business and financial profiles for relative similarity. Factors such as size, growth, risk and profitability are analyzed and compared to each of our reporting units. Assumptions include the selection of our peer companies and use of market multiples, which could deteriorate or increase based on the profitability of our competitors and performance of their stock, which is often dependent on the performance of the stock market and general economy as a whole.
Adverse changes in the assumptions utilized in our impairment test could cause a reduction or elimination of excess fair value over carrying value, resulting in potential recognition of impairment. If the fair value of the reporting unit exceeds its carrying value, no impairment charge is recorded. If the carrying value of a reporting unit exceeds its fair value, an impairment charge is recorded to goodwill in the amount by which the carrying value exceeds fair value.
We completed our annual review of goodwill for each of our reporting units for the year ended December 31, 2020, which indicated that we had no impairment of goodwill. The fair value of our reporting units was substantially in excess of carrying value.
Each year, we evaluate indefinite-lived intangible assets to assess recoverability, and impairments, if any, are recognized in earnings. We perform a qualitative assessment when testing indefinite-lived intangible assets for impairment to determine whether events or circumstances that could affect the significant inputs used in determining fair value have occurred that indicate that it is more likely than not that the indefinite-lived intangible asset is impaired. Deterioration in macroeconomic, industry and market conditions, cost factors or overall financial performance could cause us to believe a qualitative test is no longer appropriate. When quantitative assessments are performed, we primarily utilize income-based valuation approaches. Under the income-based valuation approach, we employ a relief from royalty method of valuation. This method requires significant assumptions, including assumed royalty rate, future revenues and cost of capital. Assumptions related to operating performance, such as future revenues, could be affected by loss of a customer contract, a decline in U.S. Government funding or a decline in demand based on changing economic or regulatory conditions. Changes in external market conditions may affect certain other assumptions, such as the cost of capital. Market conditions can be volatile and are outside of our control.
Adverse changes in these assumptions utilized within our indefinite-lived intangible asset impairment test could cause a reduction or elimination of excess fair value over carrying value, resulting in potential recognition of impairment.
We have completed our annual review of our indefinite-lived intangible assets for the year ended December 31, 2020, which indicated that we had no impairment. The fair value of our indefinite-lived intangible assets was substantially in excess of carrying value.
Asset Retirement Obligations and Environmental Cleanup Costs. We accrue for future decommissioning of our nuclear facilities that will permit the release of these facilities to unrestricted use at the end of each facility's service life, which is a requirement of our licenses from the NRC and the CNSC. In accordance with the FASB Topic Asset Retirement and Environmental Obligations, we record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. In estimating fair value, we use present value of cash flows expected to be incurred in settling our obligations. To the extent possible, we perform a marketplace assessment of the cost and timing of performing the retirement activities. We apply a credit-adjusted risk-free interest rate to our expected cash flows in our determination of fair value. When we initially record such a liability, we capitalize a cost by increasing the carrying amount of the related long-lived asset. When we acquire a business that has an asset retirement obligation, the asset retirement obligation is recognized at fair value without a corresponding increase to the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Actual costs incurred to decommission our facilities may differ from the accreted liability. As a result, upon completion of a decommissioning activity, we will either settle the obligation for its recorded amount or incur a gain or loss. This topic applies to environmental liabilities associated with assets that we currently operate and are obligated to remove from service. For environmental liabilities associated with assets that we no longer operate, we have accrued amounts based on the estimated costs of cleanup activities, net of the anticipated effect of any applicable cost-sharing arrangements. We adjust the estimated costs as further information develops or circumstances change. Given the long-lived nature of these facilities, we are required to estimate retirement costs that will be incurred in the future, which may extend up to 40 years at the time the asset retirement obligation is established. Due to the significance of the remaining useful life of these facilities, the timing of retirement and future costs for material components of the asset retirement

obligations, such as labor and waste disposal fees, could differ from our estimates. An exception to this accounting treatment relates to the work we perform for two facilities for which the U.S. Government is obligated to pay substantially all the decommissioning costs.
See Note 1 to our consolidated financial statements included in this Report for further discussion of recently adopted accounting standards.
COVID-19 ASSESSMENT
General
A global outbreak of COVID-19 has occurred impacting over 200 countries, including the U.S. and Canada where we maintain our principal operations. Developments have been occurring rapidly with respect to the spread of COVID-19 and its impact on human health and businesses, with new and changing government actions occurring on a daily basis. As a result, we have been closely monitoring the COVID-19 pandemic and its impacts and potential impacts on our business.
We have received notifications from the U.S. and Canadian governments designating BWXT as an essential business given our roles in national security, energy production and medical manufacturing. We continue to operate our facilities and have taken numerous precautions to mitigate exposure and protect the health and well-being of our workforce.
To date, we have experienced localized operational challenges as a result of employee illness, quarantines and social distancing protocols. Within our Canadian operations, revenues in our medical radioisotopes and radiopharmaceuticals business have declined year over year due to a decrease in demand for elective diagnostic procedures, and certain services scheduled during nuclear power plant outages have been rescheduled, delaying the performance of services by our Nuclear Power Group segment. We have also experienced delays in the bidding and contracting process for our U.S. Government businesses due to COVID-19 concerns.
Because developments related to the spread of COVID-19 and its impacts have been occurring rapidly, it is difficult to predict any future impact at this time. We may experience further disruptions to demand for our products and services and our operations in the future as a result of, among other things, national, state, provincial or local government enforced quarantines, worker illness or absenteeism, and travel and other restrictions. For similar reasons, the COVID-19 pandemic may also adversely impact our supply chain and other manufacturers which could delay our receipt of essential goods and services. Any number of these potential risks could have a material adverse effect on our financial condition, results of operations and cash flows. The extent to which the COVID-19 outbreak impacts our business will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact.
Government Assistance
On March 27, 2020, the U.S. Government enacted the CARES Act, which among other things, provides employers an option to defer payroll tax payments for a limited period. Based on our evaluation of the CARES Act, we qualify for the deferral of payroll tax payments in the future and as of December 31, 2020, and we have deferred $21.4 million of payroll taxes that will be paid beginning in December 2021. Additionally, on April 11, 2020, the Canadian Government enacted CEWS under the COVID-19 Economic Response Plan to prevent large layoffs and help employers offset a portion of their employee salaries and wages for a limited period. During the year ended December 31, 2020, we recognized $20.4 million of subsidies under CEWS as an offset to operating expenses. The Canadian Government has extended CEWS to June 2021 with a number of modifications. These modifications are expected to significantly decrease the amount of future claims for which we may qualify.
See Item 1A "Risk Factors" in this Report for an additional discussion of risks of the COVID-19 pandemic on our business.

This section discusses our 2020 and 2019 results of operations and contains year-to-year comparisons between 2020 and 2019. Discussions of our 2018 results and year-to-year comparisons between 2019 and 2018 that are not included in this Report can be found in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2019.
Consolidated Results of Operations
Consolidated revenues increased 12.1%, or $228.6 million, to $2,123.5 million in the year ended December 31, 2020 compared to $1,894.9 million for the corresponding period of 2019, due to increases in revenues from our Nuclear Operations Group, Nuclear Power Group and Nuclear Services Group segments totaling $217.7 million, $18.6 million and $5.2 million, respectively.
Consolidated operating income increased $33.0 million to $358.6 million in the year ended December 31, 2020 compared to $325.5 million for the corresponding period of 2019. Operating income in our Nuclear Operations Group, Nuclear Services Group and Other segments increased by $27.7 million, $12.2 million and $0.8 million, respectively. These increases were partially offset by lower operating income in our Nuclear Power Group segment of $1.8 million and higher Unallocated Corporate expenses of $5.9 million when compared to the prior year.

Revenues increased by 15.2%, or $217.7 million, to $1,646.3 million in the year ended December 31, 2020 compared to $1,428.6 million for the corresponding period of 2019 as we continue to expand production related to the Columbia-Class nuclear propulsion system. The increase comprised additional volume in the manufacture of nuclear components for U.S. Government programs and the timing of the procurement of certain long-lead materials when compared to the prior year. We also experienced a volume increase in our naval nuclear fuel and downblending operations.

Operating income increased $27.7 million to $326.0 million in the year ended December 31, 2020 compared to $298.3 million for the corresponding period of 2019. The increase was due to the operating income impact of the changes in revenues noted above.

Revenues increased by 5.3%, or $18.6 million, to $371.3 million in the year ended December 31, 2020 compared to $352.6 million for the corresponding period of 2019. This was primarily related to an increase in revenues of $38.0 million associated with the acquisition of Laker Energy Products during the first quarter of 2020. We also experienced additional volume related to the fabrication of nuclear fuel and a higher levels of in-plant inspection, maintenance and modification services. These increases were partially offset by lower revenues in our nuclear components business largely attributable to decreased activity associated with major steam generator design and supply contracts of $34.2 million. In addition, we experienced lower demand for our medical radioisotopes when compared to the prior year, due to a decrease in elective diagnostic procedures caused in part by the COVID-19 pandemic.
Operating income decreased $1.8 million to $52.0 million in the year ended December 31, 2020 compared to $53.8 million for the corresponding period of 2019, primarily attributable to a $5.2 million favorable change in estimate associated with an asset retirement obligation in addition to net favorable changes in estimates related to certain long-term contracts recorded in the prior year. We also experienced a shift in our product line mix when compared to the prior year which resulted in a decline in operating margins. This was offset by $20.4 million of wage subsidies received under the CEWS to offset the effects of COVID-19 on our Canadian operations.

Revenues increased by 3.9%, or $5.2 million, to $136.5 million in the year ended December 31, 2020 compared to $131.3 million for the corresponding period of 2019. The increase was primarily attributable to design and engineering work executed by our advanced technologies business which was partially offset by a decline in revenues due to the divestiture of our U.S.-based commercial nuclear services business during the second quarter of 2020.
Operating income increased $12.2 million to $26.4 million in the year ended December 31, 2020 compared to $14.2 million for the corresponding period of 2019 due to the operating income impact of the changes in revenues noted above in addition to year over year improvements in our U.S.-based commercial nuclear services business prior to divestiture.

Operating income increased $0.8 million to a loss of $22.3 million in the year ended December 31, 2020 compared to a loss of $23.1 million for the corresponding period of 2019, primarily due to a decrease in research and development activities related to our medical and industrial radioisotope capabilities and other advanced technologies when compared to the prior year.
Unallocated Corporate
Unallocated corporate expenses increased $5.9 million to $23.6 million in the year ended December 31, 2020 compared to $17.7 million for the corresponding period of 2019, primarily due to a $2.6 million reserve related to a franchise tax audit of years prior to 2016, higher levels of incentive compensation and a $1.6 million increase in legal and consulting costs associated with the divestiture of our U.S.-based commercial nuclear services business during the second quarter of 2020.
Other Income (Expense)
During the year ended December 31, 2020, other income (expense) increased $15.4 million to a gain of $3.6 million compared to a loss of $11.8 million for the corresponding period of 2019. A component of other income (expense) is net periodic benefit cost inclusive of mark to market adjustments due to our immediate recognition of net actuarial gains (losses) for our pension and postretirement benefit plans. Net periodic benefit cost resulted in an increase to other income of $14.1 million when compared to the prior year.

For the year ended December 31, 2020, our provision for income taxes increased $13.9 million to $83.0 million, while income before provision for income taxes increased $48.4 million to $362.2 million. Our effective tax rate was approximately 22.9% as compared to 22.0% for the years ended December 31, 2020 and 2019, respectively. Our effective tax rates for the years ended December 31, 2020 and 2019 were higher than the U.S. corporate income tax rate of 21% primarily due to state income taxes within the U.S. and the unfavorable rate differential associated with our Canadian earnings. These unfavorable rate impacts were partially offset by benefits recognized for excess tax benefits related to employee share-based payments of $1.1 million and $2.4 million for the years ended December 31, 2020 and 2019, respectively.
See Note 5 to our consolidated financial statements included in this Report for further information on income taxes.
EFFECTS OF INFLATION AND CHANGING PRICES
Our financial statements are prepared in accordance with GAAP, using historical U.S. dollar accounting ("historical cost"). Statements based on historical cost, however, do not adequately reflect the cumulative effect of increasing costs and changes in the purchasing power of the U.S. dollar, especially during times of significant and continued inflation.
In order to minimize the negative impact of inflation on our operations, we attempt to cover the increased cost of anticipated changes in labor, material and service costs, either through an estimate of those changes, which we reflect in the original price, or through price escalation clauses in our contracts. However, there can be no assurance we will be able to cover all changes in cost using this strategy.
LIQUIDITY AND CAPITAL RESOURCES
Our overall liquidity position, which we generally define as our unrestricted cash and cash equivalents plus amounts available for borrowings under our credit facility, increased by approximately $290.4 million to $649.3 million at December 31, 2020 compared to $358.9 million at December 31, 2019. We experienced net cash generated from operations in each of the years ended December 31, 2020, 2019 and 2018. Typically, the fourth quarter has been the period of highest cash flows from operating activities because of the timing of payments received from the U.S. Government on accounts receivable retainages and cash dividends received from our joint ventures.

On June 12, 2020, we issued $400 million aggregate principal amount of our 4.125% senior notes due 2028 (the "Senior Notes due 2028") pursuant to an indenture dated June 12, 2020 (the "2020 Indenture") among the Company, the guarantors party thereto and U.S. Bank National Association, as trustee. The proceeds from the issuance of the Senior Notes due 2028 were used to (1) repay in full the Term Loans, as defined below, under our Credit Agreement dated as of May 24, 2018 (as amended, the "Credit Facility"), (2) repay a portion of the borrowings under the Revolving Credit Facility, as defined below, under the Credit Facility and (3) pay all fees and expenses related to the issuance of the Senior Notes due 2028.
Credit Facility
On March 24, 2020, we entered into an Amendment No. 1 to Credit Agreement (the "Amendment"), which amended the Credit Facility with Wells Fargo Bank, N.A., as administrative agent, and the other lenders party thereto. The Credit Facility originally provided for a $500 million senior secured revolving credit facility (the "Revolving Credit Facility"), a $50 million U.S. dollar senior secured term loan A made available to the Company (the "USD Term Loan") and a $250 million (U.S. dollar equivalent) Canadian dollar senior secured term loan A made available to BWXT Canada Ltd. (the "CAD Term Loan" and together with the USD Term Loan, the "Term Loans"). On June 12, 2020, we repaid in full the Term Loans, at par, with a portion of the proceeds from the issuance of the Senior Notes due 2028.
The Amendment, among other things, (1) provided additional commitments to increase the Revolving Credit Facility by $250 million, such that the Revolving Credit Facility is now $750 million; (2) extended the maturity date of the Revolving Credit Facility to March 24, 2025; (3) removed BWXT Canada Ltd. as a borrower under the Revolving Credit Facility; (4) modified the applicable margin for borrowings under the Revolving Credit Facility to be, at the Company's option, either (i) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (ii) the base rate plus a margin ranging from 0.0% to 0.75% per year, in each case depending on the Company's leverage ratio; (5) modified the commitment fee on the unused portion of the Revolving Credit Facility to range from 0.15% to 0.225% per year, depending on the Company's leverage ratio; and (6) modified the letter of credit fee with respect to each financial letter of credit and performance letter of credit issued under the Revolving Credit Facility to range from 1.0% to 1.75% and 0.75% to 1.05% per year, respectively, in each case, depending on the Company's leverage ratio.
All obligations under the Revolving Credit Facility are scheduled to mature on March 24, 2025. The proceeds of loans under the Revolving Credit Facility are available for working capital needs, permitted acquisitions and other general corporate purposes.
The Credit Facility allows for additional parties to become lenders and, subject to certain conditions, for the increase of the commitments under the Credit Facility, subject to an aggregate maximum for all additional commitments of (1) the greater of (a) $250 million and (b) 65% of EBITDA, as defined in the Credit Facility, for the last four full fiscal quarters, plus (2) all voluntary prepayments of the Term Loans, plus (3) additional amounts provided the Company is in compliance with a pro forma first lien leverage ratio test of less than or equal to 2.50 to 1.00.
The Company's obligations under the Credit Facility are guaranteed, subject to certain exceptions, by substantially all of the Company's present and future wholly owned domestic restricted subsidiaries. The Credit Facility is secured by first-priority liens on certain assets owned by the Company and its subsidiary guarantors (other than its subsidiaries comprising its Nuclear Operations Group segment and a portion of its Nuclear Services Group segment).
The Revolving Credit Facility requires interest payments on revolving loans on a periodic basis until maturity. We may prepay all loans under the Credit Facility at any time without premium or penalty (other than customary Eurocurrency breakage costs), subject to notice requirements.
The Credit Facility includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted leverage ratio is 4.00 to 1.00, which may be increased to 4.50 to 1.00 for up to four consecutive fiscal quarters after a material acquisition. The minimum consolidated interest coverage ratio is 3.00 to 1.00. In addition, the Credit Facility contains various restrictive covenants, including with respect to debt, liens, investments, mergers, acquisitions, dividends, equity repurchases and asset sales. As of December 31, 2020, we were in compliance with all covenants set forth in the Credit Facility.
Outstanding loans under the Revolving Credit Facility bear interest at our option at either (1) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (2) the base rate plus a margin ranging from 0.0% to 0.75% per year. We are charged a commitment fee on the unused portion of the Revolving Credit Facility, and that fee ranges from 0.15% to 0.225% per year. Additionally, we are charged a letter of credit fee of between 1.0% and 1.75% per year with respect to the amount of each financial letter of credit issued under the Credit Facility, and a letter of credit fee of between 0.75% and 1.05% per year

with respect to the amount of each performance letter of credit issued under the Credit Facility. The applicable margin for loans, the commitment fee and the letter of credit fees set forth above will vary quarterly based on our leverage ratio. Based on the leverage ratio applicable at December 31, 2020, the margin for Eurocurrency rate and base rate revolving loans was 1.25% and 0.25%, respectively, the letter of credit fee for financial letters of credit and performance letters of credit was 1.25% and 0.825%, respectively, and the commitment fee for the unused portion of the Revolving Credit Facility was 0.175%.
As of December 31, 2020, borrowings and letters of credit issued under the Revolving Credit Facility totaled $75.0 million and $68.3 million, respectively. As a result, as of December 31, 2020 we had $606.7 million available under the Revolving Credit Facility for borrowings and to meet letter of credit requirements. As of December 31, 2020, the interest rate on outstanding borrowings under our Credit Facility was 1.41%.
The Credit Facility generally includes customary events of default for a secured credit facility. Under the Credit Facility, (1) if an event of default relating to bankruptcy or other insolvency events occurs with respect to the Company, all related obligations will immediately become due and payable; (2) if any other event of default exists, the lenders will be permitted to accelerate the maturity of the related obligations outstanding; and (3) if any event of default exists, the lenders will be permitted to terminate their commitments thereunder and exercise other rights and remedies, including the commencement of foreclosure or other actions against the collateral.
If any default occurs under the Credit Facility, or if we are unable to make any of the representations and warranties in the Credit Facility, we will be unable to borrow funds or have letters of credit issued under the Credit Facility.
Senior Notes due 2026
On May 24, 2018, we issued $400 million aggregate principal amount of 5.375% senior notes due 2026 (the "Senior Notes due 2026") pursuant to an indenture dated May 24, 2018 (the "2018 Indenture"), among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank National Association, as trustee. The Senior Notes due 2026 are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Credit Facility.
Interest on the Senior Notes due 2026 is payable semi-annually in cash in arrears on January 15 and July 15 of each year at a rate of 5.375% per annum. The Senior Notes due 2026 will mature on July 15, 2026.
On and after July 15, 2021, we may redeem the Senior Notes due 2026, in whole or in part, at a redemption price equal to (i) 102.688% of the principal amount to be redeemed if the redemption occurs during the twelve-month period beginning on July 15, 2021, (ii) 101.344% of the principal amount to be redeemed if the redemption occurs during the twelve-month period beginning on July 15, 2022 and (iii) 100.0% of the principal amount to be redeemed if the redemption occurs on or after July 15, 2023, in each case plus accrued and unpaid interest, if any, to, but excluding, the redemption date. At any time prior to July 15, 2021, we may also redeem up to 40.0% of the Senior Notes due 2026 with net cash proceeds of certain equity offerings at a redemption price equal to 105.375% of the principal amount of the Senior Notes due 2026 to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, at any time prior to July 15, 2021, we may redeem the Senior Notes due 2026, in whole or in part, at a redemption price equal to 100.0% of the principal amount of the Senior Notes due 2026 to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date plus an applicable "make-whole" premium.
The 2018 Indenture contains customary events of default, including, among other things, payment default, failure to comply with covenants or agreements contained in the 2018 Indenture or the Senior Notes due 2026 and certain provisions related to bankruptcy events. The 2018 Indenture also contains customary negative covenants. As of December 31, 2020, we were in compliance with all covenants set forth in the 2018 Indenture and the Senior Notes due 2026.

Other Arrangements
We have posted surety bonds to support regulatory and contractual obligations for certain decommissioning responsibilities, projects and legal matters. We utilize bonding facilities to support such obligations, but the issuance of bonds under those facilities is typically at the surety's discretion. Although there can be no assurance that we will maintain our surety bonding capacity, we believe our current capacity is adequate to support our existing requirements for the next twelve months. In addition, these bonds generally indemnify the beneficiaries should we fail to perform our obligations under the applicable agreements. We, and certain of our subsidiaries, have jointly executed general agreements of indemnity in favor of surety underwriters relating to surety bonds those underwriters issue. As of December 31, 2020, bonds issued and outstanding under these arrangements totaled approximately $73.7 million.

Cash, Cash Equivalents, Restricted Cash and Investments
In the aggregate, our cash and cash equivalents, restricted cash and cash equivalents and investments decreased by approximately $44.5 million to $61.4 million at December 31, 2020 from $105.9 million at December 31, 2019, primarily due to the items discussed below. Our domestic and foreign cash and cash equivalents, restricted cash and cash equivalents and investments as of December 31, 2020 and 2019 were as follows:

|  | December 31,
|  | 2020 |  | 2019

Foreign |  | 29,985 |  |  | 29,526 |
Total |  | $ | 61,361 |  |  | $ | 105,863 |

Our working capital increased by $18.8 million to $243.9 million at December 31, 2020 from $225.0 million at December 31, 2019, primarily attributable to changes in net contracts in progress and advance billings due to the timing of project cash flows. This increase was partially offset by a decrease in cash and cash equivalents and an increase in other accrued liabilities primarily related to the deferral of payroll tax payments under the CARES Act.
Our net cash provided by operating activities decreased by $82.9 million to $196.4 million in the year ended December 31, 2020, compared to cash provided by operating activities of $279.4 million in the year ended December 31, 2019, primarily attributable to the timing of project cash flows. This decrease was partially offset by an increase in net income and the deferral of payroll tax payments under the CARES Act of $21.4 million.
Our net cash used in investing activities increased by $85.3 million to $265.3 million in the year ended December 31, 2020, compared to $180.0 million in the year ended December 31, 2019. The increase in cash used in investing activities was primarily attributable to an increase in purchases of property, plant and equipment of $72.9 million as well as our acquisition of Laker Energy Products for $15.9 million during the year ended December 31, 2020.

Our net cash provided by financing activities increased by $68.8 million to $25.0 million in the year ended December 31, 2020, compared to cash used in financing activities of $43.7 million in the year ended December 31, 2019. The increase in net cash provided by financing activities was primarily attributable to bank overdrafts of $88.7 million, partially offset by the payment of debt issuance costs of $6.8 million and an increase in dividends paid to common shareholders of $7.6 million compared to the prior year.
At December 31, 2020, we had restricted cash and cash equivalents totaling $5.7 million, $2.6 million of which was held for future decommissioning of facilities (which is included in other assets on our consolidated balance sheets) and $3.1 million of which was held to meet reinsurance reserve requirements of our captive insurer.
At December 31, 2020, we had short-term and long-term investments with a fair value of $13.1 million. Our investment portfolio consists primarily of U.S. Government and agency securities, corporate bonds and equities and mutual funds.
Based on our liquidity position, we believe we have sufficient cash and letter of credit and borrowing capacity to fund our operating requirements for at least the next 12 months.
CONTRACTUAL OBLIGATIONS
Our cash requirements as of December 31, 2020 under current contractual obligations were as follows:

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our exposure to market risk from changes in interest rates relates primarily to our debt instruments. Our borrowings include both fixed and variable interest rate debt. At December 31, 2020, we had (i) $75.0 million in outstanding borrowings and $606.7 million available under the Credit Facility, (ii) an aggregate principal amount of $400.0 million of Senior Notes due 2026 and (iii) an aggregate principal amount of $400.0 million of Senior Notes due 2028. See Item 7 – "Management's Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources" for additional information on our debt instruments.
We also have exposure from changes in interest rates related to our cash equivalents and our investment portfolio, which consists primarily of U.S. Government and agency securities, corporate bonds and equities and mutual funds. We are averse to principal loss and seek to ensure the safety and preservation of our invested funds by limiting default risk, market risk and reinvestment risk.
We have operations in foreign locations, and, as a result, our financial results could be significantly affected by factors such as changes in foreign currency exchange ("FX") rates or weak economic conditions in those foreign markets. In order to manage the operational risks associated with FX rate fluctuations, we attempt to hedge those risks with FX derivative instruments. Historically, we have hedged those risks with FX forward contracts. At December 31, 2020, the fair values of our outstanding derivative instruments were not significant. We do not enter into speculative derivative positions.

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of BWX Technologies, Inc.:
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of BWX Technologies, Inc. and subsidiaries (the "Company") as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2020, 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, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, 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, 2020, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2021 expressed an unqualified opinion on the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Revenue Recognition – Estimating Costs at Completion – Refer to Note 1 and Note 3 to the Financial Statements.
Critical Audit Matter Description
The Company generally recognizes contract revenues and related costs over time for individual performance obligations based on a cost-to-cost method in accordance with Financial Accounting Standards Board Topic Revenue from Contracts with Customers. The Company recognizes estimated contract revenue and resulting income based on the measurement of the extent of progress toward completion as a percentage of the total project. The Company reviews contract price and cost estimates periodically as the work progresses and reflects adjustments proportionate to the percentage-of-completion in income in the period when those estimates are revised. The accounting for these contracts involves judgment, particularly as it relates to the process of estimating total costs to complete the performance obligation.
Given the significance of revenue and the level of judgment involved in estimating total costs to complete the performance obligations used to recognize revenue for long-term contracts, auditing such estimates involved especially subjective judgment.

Table of Contents
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to revenues recognized over time, including management’s estimates of total contract costs to complete its performance obligations included the following, among others:
•We tested the effectiveness of controls over revenue recognized over time, including those over cost estimates at completion for performance obligations.
•For select cumulative adjustments recorded, we performed a retrospective review to determine that the adjustments were the result of changes in facts and circumstances and not estimates that were previously inaccurate.
•We tested the recorded revenue using a combination of analytical procedures and detailed contract testing.
•For select contracts with customers recognized over time, our detail testing performed included the following:
◦Read the contract to understand the contract terms and evaluated the appropriateness of the accounting treatment in accordance with generally accepted accounting principles.
◦Compared the transaction price to the consideration expected to be received based on current rights and obligations under the contract, including modifications that were agreed upon with the customer.
◦Tested management’s identification of distinct performance obligations.
◦Tested the mathematical accuracy of management’s calculation of the percent complete, the profit margin and the revenue recognized over time.
◦Evaluated a selection of cost estimates within the selected contract as follows:
▪Compared costs incurred to date or costs of similar performance obligations to evaluate the reasonableness of management’s estimates.
▪Evaluated management’s ability to achieve the cost estimates by performing corroborating inquiries with the Company’s project managers and engineers, as appropriate; comparing the estimates to management’s work plans, engineering specifications, purchase orders, and/or supplier contracts as appropriate; and when considered necessary, observation of the work site to evaluate project status.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2020
NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
We have presented the consolidated financial statements of BWX Technologies, Inc. ("BWXT") in U.S. dollars in accordance with accounting principles generally accepted in the United States ("GAAP").
We use the equity method to account for investments in entities that we do not control, but over which we have the ability to exercise significant influence. We generally refer to these entities as "joint ventures." We have eliminated all intercompany transactions and accounts. We have reclassified certain amounts previously reported to conform to the presentation at December 31, 2020 and for the year ended December 31, 2020. On June 30, 2015, we completed the spin-off of our former Power Generation business (the "spin-off") into an independent, publicly traded company named Babcock & Wilcox Enterprises, Inc. ("BWE"). We present the notes to our consolidated financial statements on the basis of continuing operations, unless otherwise stated.
Unless the context otherwise indicates, "we," "us" and "our" mean BWXT and its consolidated subsidiaries.
Reportable Segments
We operate in three reportable segments: Nuclear Operations Group, Nuclear Power Group and Nuclear Services Group. Our reportable segments are further described as follows:
•Our Nuclear Operations Group segment manufactures naval nuclear reactors for the U.S. Naval Nuclear Propulsion Program for use in submarines and aircraft carriers. Through this segment, we own and operate manufacturing facilities located in Lynchburg, Virginia; Barberton, Ohio; Mount Vernon, Indiana; Euclid, Ohio; and Erwin, Tennessee. The Lynchburg operations fabricate fuel-bearing precision components that range in weight from a few grams to hundreds of tons. In-house capabilities also include wet chemistry uranium processing, advanced heat treatment to optimize component material properties and a controlled, clean-room environment with the capacity to assemble railcar-size components. The Barberton and Mount Vernon locations specialize in the design and manufacture of heavy components inclusive of fabrication activities for submarine missile launch tubes. The Euclid facility fabricates electro-mechanical equipment and performs design, manufacturing, inspection, assembly and testing activities. Fuel for the naval nuclear reactors is provided by Nuclear Fuel Services, Inc. ("NFS"), one of our wholly owned subsidiaries. Located in Erwin, NFS also downblends Cold War-era government stockpiles of high-enriched uranium.
•Our Nuclear Power Group segment fabricates commercial nuclear steam generators, nuclear fuel, fuel handling systems, pressure vessels, reactor components, heat exchangers, tooling delivery systems and other auxiliary equipment, including containers for the storage of spent nuclear fuel and other high-level waste and supplies nuclear-grade materials and precisely machined components for nuclear utility customers. BWXT has supplied the nuclear industry with more than 1,300 large, heavy components worldwide and is the only commercial heavy nuclear component manufacturer in North America. This segment also provides specialized engineering services that include structural component design, 3-D thermal-hydraulic engineering analysis, weld and robotic process development, electrical and controls engineering and metallurgy and materials engineering. In addition, this segment offers in-plant inspection, maintenance and modification services for nuclear steam generators, heat exchangers, reactors, fuel handling systems and balance of plant equipment, as well as specialized non-destructive examination and tooling/repair solutions. This segment is also a leading global manufacturer and supplier of critical medical radioisotopes and radiopharmaceuticals for research, diagnostic and therapeutic uses.
•Our Nuclear Services Group segment provides various services to the U.S. Government including nuclear materials management and operation, environmental management and administrative and operating services for various U.S. Government-owned facilities. These services are provided to the U.S. Department of Energy ("DOE"), including the National Nuclear Security Administration ("NNSA"), the Office of Nuclear Energy, the Office of Science and the Office of Environmental Management, and NASA. Through this segment we deliver services and management solutions to nuclear and high-consequence operations. A significant portion of this segment's operations is conducted through joint ventures. This segment also develops technology for a variety of applications, including advanced nuclear power sources, and offers complete advanced nuclear fuel and reactor design and engineering, licensing and manufacturing services for new advanced nuclear reactors.

See Note 15 for financial information about our segments.
Divestiture of U.S.-Based Commercial Nuclear Services Business
On May 29, 2020, our subsidiary BWXT Nuclear Energy, Inc. divested its U.S.-based commercial nuclear services business, a component of our Nuclear Services Group segment. In a cashless transaction, we exchanged net assets totaling $18.0 million, consisting primarily of property, plant and equipment and certain warranty obligations, for a manufacturing facility and the associated land of approximately the same value. The acquired assets are reported as part of the Nuclear Services Group segment.
Recently Adopted Accounting Standards
On January 1, 2020, we adopted the update to the Financial Accounting Standards Board ("FASB") Topic Financial Instruments – Credit Losses. This update requires entities to recognize expected credit losses immediately in the financial statements. We considered our customer base, credit loss history and expected loss rate in our evaluation of expected credit losses. The adoption of the provisions in this update did not have an impact on our financial position, results of operations or cash flows.
On January 1, 2020, we adopted the update to the FASB Topic Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This update simplifies the accounting for goodwill impairment by eliminating the second step from the goodwill impairment test. Goodwill impairment is now determined by comparing the fair value of a reporting unit with its carrying amount. The adoption of the provisions in this update did not have an impact on our financial position, results of operations or cash flows.
In December 2019, the FASB issued an update to the FASB Topic Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This update simplifies various aspects related to the accounting for income taxes by eliminating certain exceptions to the general principles in Topic 740, simplifies when companies recognize deferred taxes in an interim period and clarifies certain aspects of the current guidance to promote consistent application. We elected to early adopt this update effective January 1, 2020, which did not have a material impact on our financial position, results of operations or cash flows.
On January 1, 2020, we adopted the update to the FASB Topic Compensation – Retirement Benefits – Defined Benefit Plans – General. This update modifies the annual disclosure requirements for employers that sponsor defined benefit pension or other postretirement benefit plans. This update requires disclosure changes to be presented on a retrospective basis. The adoption of the provisions in this update did not have an impact on our financial position, results of operations or cash flows.
Use of Estimates
We use estimates and assumptions to prepare our financial statements in conformity with GAAP. Some of our more significant estimates include estimates of costs to complete long-term contracts and the associated revenues, estimates of the fair value of acquired intangible and other assets, estimates we make in selecting assumptions related to the valuations of our pension and postretirement benefit plans, including the selection of our discount rates, mortality and expected rates of return on our pension plan assets and estimates we make in evaluating our asset retirement obligations. These estimates and assumptions affect the amounts we report in our financial statements and accompanying notes. Our actual results could differ from these estimates. Variances could result in a material effect on our financial condition and results of operations in future periods.
Contracts and Revenue Recognition
We generally recognize contract revenues and related costs over time for individual performance obligations based on a cost-to-cost method in accordance with FASB Topic Revenue from Contracts with Customers. We recognize estimated contract revenue and resulting income based on the measurement of the extent of progress toward completion as a percentage of the total project. Certain costs may be excluded from the cost-to-cost method of measuring progress, such as significant costs for uninstalled materials, if such costs do not depict our performance in transferring control of goods or services to the customer. We review contract price and cost estimates periodically as the work progresses and reflect adjustments proportionate to the percentage-of-completion in income in the period when those estimates are revised. Certain of our contracts recognize revenue at a point in time, and revenue on these contracts is recognized when control transfers to the customer. The majority of our revenue that is recognized at a point in time is related to parts and certain medical radioisotopes and radiopharmaceuticals in our Nuclear Power Group segment. For all contracts, if a current estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full when determined.

Warranty Expense
We accrue estimated warranty expense, included in Cost of operations on our consolidated statements of income, to satisfy contractual warranty requirements when we recognize the associated revenue on the related contracts. In addition, we record specific provisions or reductions where we expect the actual warranty costs to significantly differ from the accrued estimates. Such changes could have a material effect on our consolidated financial condition, results of operations and cash flows.
The following summarizes the changes in the carrying amount of Accrued warranty expense:

|  | Year Ended December 31,
|  | 2020 |  | 2019 |  | 2018
|  | (In thousands)
Balance at beginning of period |  | $ | 9,042 |  |  | $ | 10,344 |  |  | $ | 13,428 |
Additions |  | 1,341 |  |  | 2,232 |  |  | 1,494 |
Expirations and other changes (1) |  | (1,624) |  |  | (2,728) |  |  | (3,367) |
Payments |  | (1,026) |  |  | (1,065) |  |  | (663) |
Translation and other (2) |  | (2,441) |  |  | 259 |  |  | (548) |
Balance at end of period |  | $ | 5,292 |  |  | $ | 9,042 |  |  | $ | 10,344 |

(1)Includes discounts provided to customers in satisfaction of warranty obligations totaling $(1.2) million in each of the years ended December 31, 2019 and 2018.
(2)Includes $(2.5) million related to the divestiture of the U.S.-based commercial nuclear services business during the year ended December 31, 2020.
Stock-Based Compensation
We expense stock-based compensation in accordance with FASB Topic Compensation – Stock Compensation. Under this topic, the fair value of equity-classified awards, such as restricted stock, performance shares and stock options, is determined on the date of grant and is not remeasured. The fair value of liability-classified awards, such as cash-settled stock appreciation rights, restricted stock units and performance units, is determined on the date of grant and is remeasured at the end of each reporting period through the date of settlement. Grant date fair values for restricted stock, restricted stock units, performance shares and performance units are determined using the closing price of our common stock on the date of grant.
Under the provisions of this FASB topic, we recognize expense for all share-based awards granted on a straight-line basis over the requisite service periods of the awards, which is generally equivalent to the vesting term. This topic requires compensation expense to be recognized such that compensation expense is recorded only for those awards expected to vest. As a result, we periodically review the amount of actual forfeitures and record any adjustments deemed necessary each reporting period. We also recognize excess tax benefits in our provision for income taxes. These excess tax benefits result from tax deductions in excess of the cumulative compensation expense recognized for options exercised and other equity-classified awards.
Additionally, this FASB topic amended FASB Topic Statement of Cash Flows to require excess tax benefits to be classified along with other income tax cash flows as an operating activity. In addition, cash flows related to employee taxes paid for withheld shares are classified as a financing activity.
See Note 9 for a further discussion of stock-based compensation.
Grant Accounting
We recognize amounts related to grants as a reduction of expense in the period in which the related costs for which the grants are intended to compensate are recognized and we are reasonably assured to receive payment.
On April 11, 2020, the Canadian Government enacted the Canada Emergency Wage Subsidy ("CEWS") under the COVID-19 Economic Response Plan to prevent large layoffs and help employers offset a portion of their employee salaries and wages for a limited period. During the year ended December 31, 2020, we recognized $20.4 million of subsidies under CEWS as an offset to operating expenses.

Research and Development
Our research and development activities are related to the development and improvement of new and existing products and equipment, as well as conceptual and engineering evaluation for translation into practical applications. We charge the costs of research and development unrelated to specific contracts as incurred. Contractual arrangements for customer-sponsored research and development can vary on a case-by-case basis and include contracts, cooperative agreements and grants.
Research and development activities totaled $40.8 million, $66.9 million and $63.4 million in the years ended December 31, 2020, 2019 and 2018, respectively. This includes amounts paid for by our customers of $26.6 million, $49.2 million and $48.2 million, in the years ended December 31, 2020, 2019 and 2018, respectively.
Capitalization of Interest Cost
We capitalize interest in accordance with FASB Topic Interest. We incurred total interest of $40.8 million, $41.4 million and $31.5 million in the years ended December 31, 2020, 2019 and 2018, respectively, of which we capitalized $9.8 million, $6.1 million and $3.7 million in the years ended December 31, 2020, 2019 and 2018, respectively.
Income Taxes
Income tax expense for federal, foreign, state and local income taxes is calculated on pre-tax income based on current tax law and includes the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. We assess deferred taxes and the adequacy of the valuation allowance on a quarterly basis. In the ordinary course of business, there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management's evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. We record interest and penalties (net of any applicable tax benefit) related to income taxes as a component of Provision for Income Taxes on our consolidated statements of income.
We would be subject to withholding taxes if we were to distribute earnings from certain foreign subsidiaries, and unrecognized deferred income tax liabilities, including withholding taxes, would be payable upon distribution of these earnings. We consider the earnings of our non-U.S. subsidiaries to be permanently reinvested.
Earnings Per Share
We have computed earnings per common share on the basis of the weighted-average number of common shares, and, where dilutive, common share equivalents, outstanding during the indicated periods. We issue a number of forms of stock-based compensation periodically, including incentive and non-qualified stock options, restricted stock, restricted stock units, performance shares and performance units, subject to satisfaction of specific performance goals. We include the shares applicable to these plans in our computation of diluted earnings per share when related performance criteria have been met.
Cash and Cash Equivalents and Restricted Cash and Cash Equivalents
Our cash equivalents are highly liquid investments with maturities of three months or less when we purchase them.
We record cash and cash equivalents as restricted when we are unable to freely use such cash and cash equivalents for our general operating purposes. At December 31, 2020, we had restricted cash and cash equivalents totaling $5.7 million, $2.6 million of which was held for future decommissioning of facilities (which is included in Other Assets on our consolidated balance sheets) and $3.1 million of which was held to meet reinsurance reserve requirements of our captive insurer.

Investments
Our investment portfolio consists primarily of U.S. Government and agency securities, corporate bonds and equities and mutual funds. Our debt securities are carried at fair value and are either classified as trading, with unrealized gains and losses reported in earnings, or as available-for-sale, with the unrealized gains and losses, net of tax, reported as a component of Accumulated other comprehensive income. Our equity securities are carried at fair value with the unrealized gains and losses reported in earnings. We classify investments available for current operations in the consolidated balance sheets as current assets, while we classify investments held for long-term purposes as non-current assets. We adjust the amortized cost of debt securities for amortization of premiums and accretion of discounts to maturity, and such adjustments are included in Interest income. We include realized gains and losses on our investments in Other – net. The cost of securities sold is based on the specific identification method. We include interest on securities in Interest income.
Inventories
We carry our inventory at the lower of cost or net realizable value using either the weighted average or first-in, first-out methods. At December 31, 2020 and 2019, Other current assets included inventories totaling $15.0 million and $17.1 million, respectively, consisting entirely of raw materials and supplies.
Property, Plant and Equipment
We carry our property, plant and equipment at depreciated cost, less any impairment provisions. We depreciate our property, plant and equipment using the straight-line method over estimated economic useful lives of eight to 40 years for buildings and three to 14 years for machinery and equipment. Our depreciation expense was $50.3 million, $51.0 million and $48.6 million for the years ended December 31, 2020, 2019 and 2018, respectively. We expense the costs of maintenance, repairs and renewals that do not materially prolong the useful life of an asset as we incur them.

Goodwill
Goodwill represents the excess of the cost of our acquired businesses over the fair value of the net assets acquired. We perform testing of goodwill for impairment annually. We may elect to perform a qualitative test when we believe that there is sufficient excess fair value over carrying value based on our most recent quantitative assessment, adjusted for relevant events and circumstances that could affect fair value during the current year. If we conclude based on this assessment that it is more

Table of Contents
likely than not that the reporting unit is not impaired, we do not perform a quantitative impairment test. In all other circumstances, we compare the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying value, no impairment charge is recorded. If the carrying amount of a reporting unit exceeds its fair value, an impairment charge is recorded to goodwill in the amount by which carrying value exceeds fair value.

Investments in Unconsolidated Affiliates
We use the equity method of accounting for affiliates in which we are able to exert significant influence. Currently, all of our material investments in affiliates that are not consolidated are recorded using the equity method. Affiliates in which we are unable to exert significant influence are carried at fair value.
Intangible Assets
Intangible assets are recognized at fair value when acquired. Intangible assets with definite lives are amortized to Costs and Expenses using the straight-line method over their estimated useful lives and tested for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable. Intangible assets with indefinite lives are not amortized and are subject to annual impairment testing. We may elect to perform a qualitative assessment when testing indefinite-lived intangible assets for impairment to determine whether events or circumstances affecting significant inputs related to the most recent quantitative evaluation have occurred, indicating that it is more likely than not that the indefinite-lived intangible asset is impaired. Otherwise, we test indefinite-lived intangible assets for impairment by quantitatively determining the fair value of the indefinite-lived intangible asset and comparing the fair value of the intangible asset to its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, we recognize impairment for the amount of the difference.

Leases
We lease certain manufacturing facilities, office space and equipment under operating leases with terms of one to 20 years. Certain of the leases include options to renew for periods of one to 10 years. We include lease options in our determination of the right-of-use asset and lease liability if it is reasonably certain that we will exercise one or more of the options. Leases with initial terms of 12 months or less are excluded from our right-of-use assets and lease liabilities. Our right-of-use assets are included in Other Assets on our consolidated balance sheet. Our current lease liabilities are included in Accrued liabilities – other, and our noncurrent lease liabilities are included in Other Liabilities on our consolidated balance sheet. We use discount rates based on our incremental borrowing rate as most of our leases do not provide an implicit rate that can be readily determined.
During the year ended December 31, 2020, we recognized lease expense of $7.7 million, which included $1.5 million related to the amortization of favorable lease agreements, and paid cash of $6.2 million for our operating leases. During the years ended December 31, 2019 and 2018, we recognized lease expense of $8.1 million and $6.2 million, respectively. At December 31, 2020, our weighted-average remaining lease term was 5.6 years, and for the purpose of measuring the present value of our lease liabilities, the weighted-average discount rate was 4.64%. The maturities of our lease liabilities at December 31, 2020 were as follows (amounts in thousands):

2021 |  | $ | 3,348 |
2022 |  | 1,926 |
2023 |  | 1,182 |

(1)Includes current lease liabilities of $3.3 million.
At December 31, 2020, our right-of-use assets totaled $41.3 million. The difference between the right-of-use assets and lease liabilities was primarily the result of our adoption of the update to the FASB Topic Leases on January 1, 2019, which resulted in reclassifications from Intangible Assets of favorable leases related to recent acquisitions.
Deferred Debt Issuance Costs
We have included deferred debt issuance costs in the consolidated balance sheets as a direct deduction from the carrying amount of our debt liability. We amortize deferred debt issuance costs as interest expense over the life of the related debt. The following summarizes the changes in the carrying amount of these assets:

|  | Year Ended December 31,

Balance at end of period |  | $ | 12,269 |  |  | $ | 8,006 |  |  | $ | 9,583 |

(1)Includes the recognition of prior deferred debt issuance costs associated with former credit facilities of $(0.7) million and $(2.4) million for the years ended December 31, 2020 and 2018, respectively.
Pension Plans and Postretirement Benefits
We sponsor various defined benefit pension and postretirement benefit plans covering certain employees of our U.S. and Canadian subsidiaries. We utilize actuarial valuations to calculate the cost and benefit obligations of our pension and postretirement benefits. The actuarial valuations utilize significant assumptions in the determination of our benefit cost and obligations, including assumptions regarding discount rates, expected returns on plan assets, mortality and health care cost trends. We determine our discount rate based on a yield curve comprised of rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of our pension and postretirement
56

Table of Contents
benefit plan obligations. The expected rate of return on plan assets assumption is based on capital market assumptions of the long-term expected returns for the investment mix of assets currently in the portfolio. The expected rate of return on plan assets is determined to be the weighted-average of the nominal returns based on the weightings of the classes within the total asset portfolio. Expected health care cost trends represent expected annual rates of change in the cost of health care benefits and are estimated based on analysis of health care cost inflation.
The components of benefit cost related to service cost, interest cost, expected return on plan assets and prior service cost amortization are recorded on a quarterly basis based on actuarial assumptions. In the fourth quarter of each year, or as interim remeasurements are required, we immediately recognize net actuarial gains and losses in earnings as a component of net periodic benefit cost. Recognized net actuarial gains and losses consist primarily of our reported actuarial gains and losses and the difference between the actual return on plan assets and the expected return on plan assets.
We recognize the funded status of each plan as either an asset or a liability in the consolidated balance sheets. The funded status is the difference between the fair value of plan assets and the present value of its benefit obligation, determined on a plan-by-plan basis. Our pension plan assets can include assets that are difficult to value. See Note 7 for detailed information regarding our plan assets.
Asset Retirement Obligations and Environmental Cleanup Costs
We accrue for future decommissioning of our nuclear facilities that will permit the release of these facilities to unrestricted use at the end of each facility's service life, which is a requirement of our licenses from the U.S. Nuclear Regulatory Commission ("NRC") and the Canadian Nuclear Safety Commission ("CNSC"). In accordance with the FASB Topic Asset Retirement and Environmental Obligations, we record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When we initially record such a liability, we capitalize a cost by increasing the carrying amount of the related long-lived asset. When we acquire a business that has an asset retirement obligation, the asset retirement obligation is recognized at fair value without a corresponding increase to the related long-lived asset. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of a liability, we will settle the obligation for its recorded amount or incur a gain or loss. This topic applies to environmental liabilities associated with assets that we currently operate and are obligated to remove from service. For environmental liabilities associated with assets that we no longer operate, we have accrued amounts based on the estimated costs of cleanup activities for which we are responsible, net of any cost-sharing arrangements. We adjust the estimated costs as further information develops or circumstances change. Given the long-lived nature of these facilities, we are required to estimate retirement costs that will be incurred in the future, which may extend up to 40 years at the time the asset retirement obligation is established. Due to the significance of the remaining useful life of these facilities, the timing of retirement and future costs for material components of the asset retirement obligations, such as labor and waste disposal fees, could differ from our estimates. An exception to this accounting treatment relates to the work we perform for two facilities for which the U.S. Government is obligated to pay substantially all of the decommissioning costs.
Substantially all of our asset retirement obligations relate to the remediation of our nuclear analytical laboratory and the NFS facility in our Nuclear Operations Group segment as well as certain facilities in our Nuclear Power Group segment. The following summarizes the changes in the carrying amount of these liabilities:

|  | Year Ended December 31,

Self-Insurance
We have a wholly owned insurance subsidiary that provides employer's liability, general and automotive liability and primary workers' compensation insurance and, from time to time, builder's risk insurance (within certain limits) to our companies. We may also, in the future, have this insurance subsidiary accept other risks that we cannot or do not wish to transfer to outside insurance companies. Included in Other Liabilities on our consolidated balance sheets are reserves for self-insurance totaling $5.0 million and $5.2 million at December 31, 2020 and 2019, respectively.
Loss Contingencies
We accrue liabilities for loss contingencies when it is probable that a liability has been incurred and the amount of loss is reasonably estimable. We provide disclosure when there is a reasonable possibility that the ultimate loss will exceed the recorded provision or if such probable loss is not reasonably estimable. Due to the nature of our business, we are, from time to time, involved in investigations, litigation, disputes or claims related to our business activities, as discussed in Note 10. Our losses are typically resolved over long periods of time and are often difficult to assess and estimate due to, among other reasons, the possibility of multiple actions by third parties; the attribution of damages, if any, among multiple defendants; plaintiffs, in most cases involving personal injury claims, do not specify the amount of damages claimed; the discovery process may take multiple years to complete; during the litigation process, it is common to have multiple complex unresolved procedural and substantive issues; the potential availability of insurance and indemnity coverages; the wide-ranging outcomes reached in similar cases, including the variety of damages awarded; the likelihood of settlements for de minimus amounts prior to trial; the likelihood of success at trial; and the likelihood of success on appeal. Consequently, it is possible future earnings could be affected by changes in our assessments of the probability that a loss has been incurred in a material pending litigation against us and/or changes in our estimates related to such matters.

Foreign Currency Translation
We translate assets and liabilities of our foreign operations into U.S. dollars at current exchange rates, and we translate income statement items at average exchange rates for the periods presented. We record adjustments resulting from the translation of foreign currency financial statements as a component of Accumulated other comprehensive income. We report foreign currency transaction gains and losses in income. We have included in Other – net transaction gains (losses) of $(0.6) million, $1.0 million and $2.0 million for the years ended December 31, 2020, 2019 and 2018, respectively.
Derivative Financial Instruments
Our operations give rise to exposure to market risks from changes in foreign currency exchange ("FX") rates. We use derivative financial instruments, primarily FX forward contracts, to reduce the impact of changes in FX rates on our operating results. We use these instruments to hedge our exposure associated with revenues or costs on our long-term contracts and other transactions that are denominated in currencies other than our operating entities' functional currencies. We do not hold or issue derivative financial instruments for trading or other speculative purposes.
We enter into derivative financial instruments primarily as hedges of certain firm purchase and sale commitments and loans between domestic and foreign subsidiaries denominated in foreign currencies. We record these contracts at fair value on our consolidated balance sheets. Based on the hedge designation at inception of the contract, the related gains and losses on these contracts are deferred in stockholders' equity as a component of Accumulated other comprehensive income until the hedged item is recognized in earnings. The gain or loss on a derivative instrument not designated as a hedging instrument is immediately recognized in earnings. Gains and losses on derivative financial instruments that require immediate recognition are included as a component of Other – net on our consolidated statements of income and are recorded in the statements of cash flows based on the nature and use of the instruments.
We have designated the majority of our FX forward contracts that qualify for hedge accounting as cash flow hedges. The hedged risk is the risk of changes in functional-currency-equivalent cash flows attributable to changes in FX spot rates of forecasted transactions primarily related to long-term contracts. We exclude from our assessment of effectiveness the portion of the fair value of the FX forward contracts attributable to the difference between FX spot rates and FX forward rates. At December 31, 2020, we had deferred approximately $(0.5) million of net losses on these derivative financial instruments. Assuming market conditions continue, we expect to recognize the majority of this amount in the next twelve months. For the years ended December 31, 2020, 2019 and 2018, we recognized $8.7 million, $(1.0) million and $(4.7) million, respectively, of (gains) losses associated with FX forward contracts not designated as hedges.
59

Table of Contents
At December 31, 2020, our derivative financial instruments consisted of FX forward contracts with a total notional value of $245.3 million with maturities extending to March 2023. These instruments consist primarily of FX forward contracts to purchase or sell Canadian dollars and Euros. We are exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments. We attempt to mitigate this risk by using major financial institutions with high credit ratings. Our counterparties to derivative financial instruments have the benefit of the same collateral arrangements and covenants as described under our credit facility.
NOTE 2 – ACQUISITIONS
Laker Energy Products Ltd.
On January 2, 2020, our subsidiary BWXT Canada Ltd. acquired Laker Energy Products Ltd. ("Laker Energy Products") for CAD 23.3 million ($17.8 million U.S. dollar equivalent). At December 31, 2020, we are subject to the payment of contingent consideration totaling CAD 5.0 million, of which we have recognized CAD 2.5 million as a component of the purchase price. Our purchase price allocation resulted in the recognition of $8.4 million of Property, Plant and Equipment, Net, $8.2 million of Intangible Assets and $5.8 million of Goodwill. In addition, we recognized right-of-use assets and lease liabilities of $2.7 million. Laker Energy Products is a global supplier of nuclear-grade materials and precisely machined components for CANDU nuclear power utilities and employs approximately 140 personnel. Laker Energy Products is reported as part of our Nuclear Power Group segment.
Nordion Medical Isotope Business
On July 30, 2018, our subsidiary BWXT ITG Canada, Inc. acquired the Nordion medical isotope business (the "MI business") for $213.0 million. The MI business is a leading global manufacturer and supplier of critical medical radioisotopes and radiopharmaceuticals for research, diagnostic and therapeutic uses. Its customers include radiopharmaceutical companies, hospitals and radiopharmacies. Its primary operations are located in Kanata, Ontario, Canada and Vancouver, British Columbia, Canada. This acquisition added approximately 150 highly trained and experienced personnel, two specialized production centers and a uniquely licensed infrastructure. In addition to the growing portfolio of radioisotope products we acquired, the MI business will be the platform from which we plan to launch our Molybdenum-99 product line and a number of future radioisotope-based imaging, diagnostic and therapeutic products. This business is reported as part of our Nuclear Power Group segment.
The purchase price of the acquisition has been allocated among assets acquired and liabilities assumed at fair value, with the excess purchase price recorded as goodwill. Our purchase price allocation is as follows (amounts in thousands):

•Increase in amortization expense related to timing of amortization of the fair value of identifiable intangible assets acquired of approximately $3.5 million and $6.0 million for the years ended December 31, 2018 and 2017, respectively.
•Additional interest expense associated with the incremental borrowings that would have been incurred to acquire the MI business as of January 1, 2017 of approximately $2.4 million and $5.2 million for the years ended December 31, 2018 and 2017, respectively.
•Elimination of $2.5 million in acquisition related costs recognized in the year ended December 31, 2018 that are not expected to be recurring.
NOTE 3 – REVENUE RECOGNITION
The adoption of FASB Topic Revenue from Contracts with Customers, which was recognized in a cumulative catch-up adjustment on January 1, 2018, resulted in an increase to Retained earnings of $9.9 million.
Within our Nuclear Operations Group segment, we continue to recognize revenue over time and now measure progress on performance obligations using a cost-to-cost method. Prior to January 1, 2018, we utilized man-hours or a cost-to-cost method to measure progress on certain performance obligations within this segment. The performance obligations identified for recognizing revenue are similar to our historical units of account. As a result of the change to a cost-to-cost method, the timing of revenue recognition on affected contracts, in the aggregate, results in the recognition of revenue and cost of operations earlier in the process of satisfying performance obligations. This change impacted the life-to-date revenue and cost of operations recognized on performance obligations, and the adjustment to capture the impact of the new revenue recognition standard was recorded as a cumulative catch-up adjustment in Retained earnings.
The impact of the adoption of the new revenue standard on our Nuclear Power Group and Nuclear Services Group segments was not material.
Contracts and Revenue Recognition
Nuclear Operations Group
Our Nuclear Operations Group segment recognizes revenue over time for the manufacturing of naval nuclear reactor components and fuel, submarine missile launch tubes and the downblending of high-enriched uranium. Certain of our contracts
61

Table of Contents
contain two or more different types of components, each of which we identify as a separate performance obligation. We recognize revenue using a cost-to-cost method to measure progress as control is continually transferred to the customer as we incur costs on the performance obligations. We allocate revenue to the individual performance obligations within contracts with multiple performance obligations based on the stand-alone selling price of the individual performance obligations.
Our fixed-price incentive fee contracts include incentives that we concluded to be variable consideration. The amount of the variable consideration to which we are entitled is dependent on our actual costs incurred on the performance obligation compared to the target costs for that performance obligation and subject to incentive price revisions included within the contracts. We include these incentive fees in revenue when there is sufficient evidence to determine that the variable consideration is not constrained. The remaining contracts typically have immaterial amounts of variable consideration and have a single performance obligation. Our estimates of variable consideration and total estimated costs at completion are determined through a detailed process based on historical performance and our expertise using the most likely method. Variations from estimated contract performance could result in a material effect on our financial condition and results of operations in future periods.
Our Nuclear Operations Group segment's contracts primarily allow for billings as costs are incurred, subject to certain retainages on our fixed-price incentive fee contracts, that require milestones to be reached for the remaining consideration to be paid. Our fuel and downblending contracts allow billing when we achieve certain milestones related to our progress.
Nuclear Power Group
Our Nuclear Power Group segment recognizes revenue over time using a cost-to-cost method for the manufacturing of large components, non-standard parts, fuel bundles and service contracts as control continually transfers to the customers. For standard parts, revenue is recognized at the point in time control transfers to the customer, which is consistent with the transfer of ownership. For medical radioisotopes, we recognize revenue either at the point in time control transfers to the customer or over time using a unit of output method. This segment generates revenue primarily from firm-fixed-price contracts that do not contain variable consideration as well as time-and-materials based contracts. Certain of these contracts contain assurance warranties and/or provisions for liquidated damages, which are expected to have an immaterial impact to the contracts based on our historical experience. We are entitled to payment on the majority of our Nuclear Power Group segment contracts when we achieve certain milestones related to our progress.
Nuclear Services Group
Our contracts within our Nuclear Services Group segment are primarily cost-plus service contracts on which we recognize revenue over time based on a cost-to-cost method, which is consistent with the structure of the billings associated with these contracts. Ownership continuously transfers to the customer as we perform the services. The contracts within this segment do not contain significant variable consideration and contain a single performance obligation.

Performance Obligations
As we progress on our contracts and the underlying performance obligations for which we recognize revenue over time, we refine our estimates of variable consideration and total estimated costs at completion, which impact the overall profitability on our contracts and performance obligations. Changes in these estimates result in the recognition of cumulative catch-up adjustments that impact our revenues and/or costs of contracts. During the years ended December 31, 2020, 2019 and 2018, we recognized net favorable changes in estimates that resulted in increases in revenues of $44.9 million, $70.9 million and $58.6 million, respectively, as well as increases (decreases) in cost of operations of $2.1 million, $(0.7) million and $12.3 million, respectively. Included in these 2018 amounts are contract adjustments resulting from rework issues related to the manufacture of non-nuclear components being produced within our Nuclear Operations Group segment. We recognized a decrease in operating income of $29.2 million for the year ended December 31, 2018 related to this matter, which resulted in a decrease in earnings per share of $0.23.
Contract Assets and Liabilities
We include revenues and related costs incurred, plus accumulated contract costs that exceed amounts invoiced to customers under the terms of the contracts, in Contracts in progress. We include in Advance billings on contracts billings that exceed accumulated contract costs and revenues and costs recognized over time. Amounts that are withheld on our fixed-price incentive fee contracts are classified within Retainages. Certain of these amounts require conditions other than the passage of time to be achieved, with the remaining amounts only requiring the passage of time. Most long-term contracts contain provisions for progress payments. Our unbilled receivables do not contain an allowance for credit losses as we expect to invoice customers and collect all amounts for unbilled revenues. Changes in Contracts in progress and Advance billings on contracts are primarily driven by differences in the timing of revenue recognition and billings to our customers. During the year ended December 31, 2020, our unbilled receivables increased $70.4 million primarily as a result of the timing of milestone billings in our Nuclear Power Group segment and the acquisition of Laker Energy Products. Our fixed-price incentive fee contracts for our Nuclear Operations Group segment include provisions that result in an increase in retainages on contracts during the first and third quarters of the year, with larger payments made during the second and fourth quarters. Retainages also vary as a result of timing differences between incurring costs and achieving milestones that allow us to recover these amounts.

NOTE 5 – INCOME TAXES
We are subject to federal income tax in the U.S. and Canada as well as income tax within multiple U.S. state jurisdictions. We provide for income taxes based on the enacted tax laws and rates in the jurisdictions in which we conduct our operations. These jurisdictions may have regimes of taxation that vary with respect to nominal rates and with respect to the basis on which these rates are applied. This variation, along with the changes in our mix of income within these jurisdictions, can contribute to shifts in our effective tax rate from period to period.
We are currently under audit by various state and international authorities. With few exceptions, we do not have any returns under examination for years prior to 2017.
We apply the provisions of FASB Topic Income Taxes regarding the treatment of uncertain tax positions. A reconciliation of unrecognized tax benefits (exclusive of interest and federal and state benefits) is as follows:

|  | Year Ended December 31,
|  | 2020 |  | 2019 |  | 2018

Increases based on tax positions taken in the prior years |  | — |  |  | — |  |  | — |
Decreases based on tax positions taken in the prior years |  | — |  |  | — |  |  | — |
Decreases due to settlements with tax authorities |  | — |  |  | — |  |  | — |
Decreases due to lapse of applicable statute of limitation |  | (123) |  |  | (127) |  |  | (1,379) |

Balance at end of period |  | $ | 5,852 |  |  | $ | 3,899 |  |  | $ | 274 |

The unrecognized tax benefits balance of $5.9 million at December 31, 2020 would reduce our effective tax rate if recognized.
We believe that, within the next 12 months, it is reasonably possible that our entire previously unrecognized tax benefits will be resolved with the appropriate taxing jurisdiction.

The following is a reconciliation of our income tax provision from the U.S. statutory federal tax rate to our consolidated effective tax rate:

In the year ended December 31, 2018, we recognized $13.5 million of benefit in our provision for income taxes related to the remeasurement of our deferred tax assets as a result of accelerating additional contributions to certain of our domestic pension plans for inclusion in our 2017 U.S. tax return.
At December 31, 2020, we had a valuation allowance of $12.9 million for deferred tax assets, which we expect cannot be realized through carrybacks, future reversals of existing taxable temporary differences and our estimate of future taxable income. We believe that our remaining deferred tax assets are more likely than not realizable through carrybacks, future reversals of existing taxable temporary differences and our estimate of future taxable income. Any changes to our estimated valuation allowance could be material to our consolidated financial statements.
The following is an analysis of our valuation allowance for deferred tax assets:

We have federal capital losses of $7.2 million available to offset future capital gains. These federal capital losses begin to expire in the year 2023. We are carrying a full valuation allowance of $7.2 million against the deferred tax asset related to these federal capital loss carryforwards.
In addition, we have state credits and state net operating losses of $8.6 million ($6.8 million net of federal tax benefit) available to offset future taxable income in various states. These state net operating loss carryforwards begin to expire in the

year 2021. We are carrying a valuation allowance of $7.2 million ($5.7 million net of federal tax benefit) against the deferred tax asset related to the state credits and state loss carryforwards.
We would be subject to withholding taxes if we were to distribute earnings from certain foreign subsidiaries. As of December 31, 2020, the undistributed earnings of these subsidiaries were approximately $209.8 million, and our unrecognized deferred income tax liabilities of approximately $10.5 million would be payable upon the distribution of these earnings. All of our foreign earnings are considered indefinitely reinvested.

On June 12, 2020, we issued $400 million aggregate principal amount of our 4.125% senior notes due 2028 (the "Senior Notes due 2028") pursuant to an indenture dated June 12, 2020 (the "2020 Indenture") among the Company, the guarantors party thereto and U.S. Bank National Association, as trustee. The proceeds from the issuance of the Senior Notes due 2028 were used to (1) repay in full the Term Loans, as defined below, under our Credit Agreement dated as of May 24, 2018 (as amended, the "Credit Facility"), (2) repay a portion of the borrowings under the Revolving Credit Facility, as defined below, under the Credit Facility and (3) pay all fees and expenses related to the issuance of the Senior Notes due 2028.
Credit Facility
On March 24, 2020, we entered into an Amendment No. 1 to Credit Agreement (the "Amendment"), which amended the Credit Facility with Wells Fargo Bank, N.A., as administrative agent, and the other lenders party thereto. The Credit Facility originally provided for a $500 million senior secured revolving credit facility (the "Revolving Credit Facility"), a $50 million U.S. dollar senior secured term loan A made available to the Company (the "USD Term Loan") and a $250 million (U.S. dollar equivalent) Canadian dollar senior secured term loan A made available to BWXT Canada Ltd. (the "CAD Term Loan" and together with the USD Term Loan, the "Term Loans"). On June 12, 2020, we repaid in full the Term Loans, at par, with a portion of the proceeds from the issuance of the Senior Notes due 2028.
The Amendment, among other things, (1) provided additional commitments to increase the Revolving Credit Facility by $250 million, such that the Revolving Credit Facility is now $750 million; (2) extended the maturity date of the Revolving Credit Facility to March 24, 2025; (3) removed BWXT Canada Ltd. as a borrower under the Revolving Credit Facility; (4) modified the applicable margin for borrowings under the Revolving Credit Facility to be, at the Company's option, either (i) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (ii) the base rate plus a margin ranging from 0.0% to 0.75% per year, in each case depending on the Company's leverage ratio; (5) modified the commitment fee on the unused portion of the Revolving Credit Facility to range from 0.15% to 0.225% per year, depending on the Company's leverage ratio; and (6) modified the letter of credit fee with respect to each financial letter of credit and performance letter of credit issued under the Revolving Credit Facility to range from 1.0% to 1.75% and 0.75% to 1.05% per year, respectively, in each case, depending on the Company's leverage ratio.
All obligations under the Revolving Credit Facility are scheduled to mature on March 24, 2025. The proceeds of loans under the Revolving Credit Facility are available for working capital needs, permitted acquisitions and other general corporate purposes.

The Credit Facility allows for additional parties to become lenders and, subject to certain conditions, for the increase of the commitments under the Credit Facility, subject to an aggregate maximum for all additional commitments of (1) the greater of (a) $250 million and (b) 65% of EBITDA, as defined in the Credit Facility, for the last four full fiscal quarters, plus (2) all voluntary prepayments of the Term Loans, plus (3) additional amounts provided the Company is in compliance with a pro forma first lien leverage ratio test of less than or equal to 2.50 to 1.00.
The Company's obligations under the Credit Facility are guaranteed, subject to certain exceptions, by substantially all of the Company's present and future wholly owned domestic restricted subsidiaries. The Credit Facility is secured by first-priority liens on certain assets owned by the Company and its subsidiary guarantors (other than its subsidiaries comprising its Nuclear Operations Group segment and a portion of its Nuclear Services Group segment).
The Revolving Credit Facility requires interest payments on revolving loans on a periodic basis until maturity. We may prepay all loans under the Credit Facility at any time without premium or penalty (other than customary Eurocurrency breakage costs), subject to notice requirements.
The Credit Facility includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted leverage ratio is 4.00 to 1.00, which may be increased to 4.50 to 1.00 for up to four consecutive fiscal quarters after a material acquisition. The minimum consolidated interest coverage ratio is 3.00 to 1.00. In addition, the Credit Facility contains various restrictive covenants, including with respect to debt, liens, investments, mergers, acquisitions, dividends, equity repurchases and asset sales. As of December 31, 2020, we were in compliance with all covenants set forth in the Credit Facility.
Outstanding loans under the Revolving Credit Facility bear interest at our option at either (1) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (2) the base rate plus a margin ranging from 0.0% to 0.75% per year. We are charged a commitment fee on the unused portion of the Revolving Credit Facility, and that fee ranges from 0.15% to 0.225% per year. Additionally, we are charged a letter of credit fee of between 1.0% and 1.75% per year with respect to the amount of each financial letter of credit issued under the Credit Facility, and a letter of credit fee of between 0.75% and 1.05% per year with respect to the amount of each performance letter of credit issued under the Credit Facility. The applicable margin for loans, the commitment fee and the letter of credit fees set forth above will vary quarterly based on our leverage ratio. Based on the leverage ratio applicable at December 31, 2020, the margin for Eurocurrency rate and base rate revolving loans was 1.25% and 0.25%, respectively, the letter of credit fee for financial letters of credit and performance letters of credit was 1.25% and 0.825%, respectively, and the commitment fee for the unused portion of the Revolving Credit Facility was 0.175%.
As of December 31, 2020, borrowings and letters of credit issued under the Revolving Credit Facility totaled $75.0 million and $68.3 million, respectively. As a result, as of December 31, 2020 we had $606.7 million available under the Revolving Credit Facility for borrowings and to meet letter of credit requirements. As of December 31, 2020, the interest rate on outstanding borrowings under our Credit Facility was 1.41%.
The Credit Facility generally includes customary events of default for a secured credit facility. Under the Credit Facility, (1) if an event of default relating to bankruptcy or other insolvency events occurs with respect to the Company, all related obligations will immediately become due and payable; (2) if any other event of default exists, the lenders will be permitted to accelerate the maturity of the related obligations outstanding; and (3) if any event of default exists, the lenders will be permitted to terminate their commitments thereunder and exercise other rights and remedies, including the commencement of foreclosure or other actions against the collateral.
If any default occurs under the Credit Facility, or if we are unable to make any of the representations and warranties in the Credit Facility, we will be unable to borrow funds or have letters of credit issued under the Credit Facility.
Senior Notes due 2026
On May 24, 2018, we issued $400 million aggregate principal amount of 5.375% senior notes due 2026 (the "Senior Notes due 2026") pursuant to an indenture dated May 24, 2018 (the "2018 Indenture"), among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank National Association, as trustee. The Senior Notes due 2026 are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Credit Facility.
Interest on the Senior Notes due 2026 is payable semi-annually in cash in arrears on January 15 and July 15 of each year at a rate of 5.375% per annum. The Senior Notes due 2026 will mature on July 15, 2026.

On June 12, 2020, we issued $400 million aggregate principal amount of our Senior Notes due 2028 pursuant to the 2020 Indenture.

The 2020 Indenture also contains customary negative covenants. As of December 31, 2020, we were in compliance with all covenants set forth in the 2020 Indenture and the Senior Notes due 2028.
Other Arrangements
We have posted surety bonds to support regulatory and contractual obligations for certain decommissioning responsibilities, projects and legal matters. We utilize bonding facilities to support such obligations, but the issuance of bonds under those facilities is typically at the surety's discretion, and the bonding facilities generally permit the surety, in its sole discretion, to terminate the facility or demand collateral. Although there can be no assurance that we will maintain our surety bonding capacity, we believe our current capacity is adequate to support our existing requirements for the next twelve months. In addition, these bonds generally indemnify the beneficiaries should we fail to perform our obligations under the applicable agreements. We, and certain of our subsidiaries, have jointly executed general agreements of indemnity in favor of surety underwriters relating to surety bonds those underwriters issue. As of December 31, 2020, bonds issued and outstanding under these arrangements totaled approximately $73.7 million.
NOTE 7 – PENSION PLANS AND POSTRETIREMENT BENEFITS
We have historically provided defined benefit retirement benefits, primarily through noncontributory pension plans, for most of our regular employees. Certain of our subsidiaries have made other benefits available to certain groups of employees,
71

Table of Contents
including postretirement health care and life insurance benefits. For salaried employees, all major U.S. and Canadian defined benefit retirement plans have been closed to new entrants, and benefit accruals have ceased. For hourly employees, certain defined benefit retirement plans have been closed to new entrants.
Our funding policy is to fund the plans as recommended by the respective plan actuaries and in accordance with the Employee Retirement Income Security Act of 1974, as amended, or other applicable law. Assuming we continue as a government contractor, our contractual arrangements with the U.S. Government provide for the recovery of contributions to our pension and other postretirement benefit plans covering employees working primarily in our Nuclear Operations Group segment.

Net periodic benefit cost related to our pension plans is calculated in accordance with GAAP. In addition, we calculate pension costs in accordance with U.S. cost accounting standards ("CAS") for purposes of cost recovery on our U.S. Government contracts to the extent applicable. See further discussion of CAS pension costs in our discussion of Critical Accounting Policies and Estimates included in Item 7 of this Annual Report on Form 10-K.
Recognized net actuarial losses (gains) consist primarily of our reported actuarial losses (gains), settlements, and the differences between the actual returns on plan assets and the expected returns on plan assets. The benefit obligation of our pension plans as of December 31, 2020 and 2019 increased by $124.2 million and $156.8 million, respectively, due primarily to decreases in the discount rate.
In July 2018, we completed the purchase of a group annuity contract that transferred certain domestic pension benefit obligations of approximately $240 million to an insurance company for approximately 1,300 retirees. As a result, we recognized pension settlement-related charges of $10.4 million during 2018.
We made contributions to our pension and postretirement benefit plans totaling $159.0 million during the year ended December 31, 2018. In August 2018, we accelerated $118.1 million of pension contributions to certain domestic pension plans in order to capture a tax benefit in our 2017 U.S. tax return due to the change in corporate tax rates.

The expected return on plan assets rate assumptions are based on the long-term expected returns for the investment mix of assets in the portfolio. In setting these rates, we use a building-block approach. Historical real return trends for the various asset classes in the plan's portfolio are combined with anticipated future market conditions to estimate the real rate of return for each asset class. These rates are then adjusted for anticipated future inflation to estimate nominal rates of return for each asset class. The expected rate of return on plan assets is then determined to be the weighted-average nominal return based on the weightings of the asset classes within the total asset portfolio.
Our existing other benefit plans are unfunded, with the exception of the NFS postretirement benefit plans. These plans provide health benefits to certain salaried and hourly employees, as well as retired employees, of NFS. All of the assets for these postretirement benefit plans are contributed into a Voluntary Employees' Beneficiary Association trust.

Investment Goals
General
The overall investment strategy of the pension trusts is to achieve long-term growth of principal, while avoiding excessive risk and to minimize the probability of loss of principal over the long term. The specific investment goals that have been set for the pension trusts, in the aggregate, are (1) to ensure that plan liabilities are met when due and (2) to achieve an investment return on trust assets consistent with a reasonable level of risk.
Allocations to each asset class for both domestic and foreign plans are reviewed periodically and rebalanced, if appropriate, to assure the continued relevance of the goals, objectives and strategies. The pension trusts for both our domestic and foreign plans employ a professional investment advisor and a number of professional investment managers whose individual benchmarks are, in the aggregate, consistent with the plan's overall investment objectives.
The goals of each investment manager are (1) to meet (in the case of passive accounts) or exceed (for actively managed accounts) the benchmark selected and agreed upon by the manager and the pension trust and (2) to display an overall level of risk in its portfolio that is consistent with the risk associated with the agreed upon benchmark.
The investment performance of total portfolios, as well as asset class components, is periodically measured against commonly accepted benchmarks, including the individual investment manager benchmarks. In evaluating investment manager performance, consideration is also given to personnel, strategy, research capabilities, organizational and business matters, adherence to discipline and other qualitative factors that may impact the ability to achieve desired investment results.

NOTE 9 – STOCK-BASED COMPENSATION
BWX Technologies, Inc. 2020 Omnibus Incentive Plan
In May 2020, our stockholders approved the 2020 Omnibus Incentive Plan (the "2020 Plan") which succeeded the 2010 Long-Term Incentive Plan of BWX Technologies, Inc. (the "2010 Plan"). Members of the Board of Directors, executive officers, key employees and consultants are eligible to participate in the 2020 Plan. The Compensation Committee of the Board of Directors selects the participants for the 2020 Plan. The 2020 Plan provides for cash awards and equity-based compensation in the form of stock options, restricted stock, restricted stock units, performance shares and performance units, subject to satisfaction of specific performance goals. Shares subject to awards under either the 2020 Plan or the 2010 Plan that are cancelled, forfeited, terminated or expire unexercised, shall immediately become available for the granting of awards under the 2020 Plan. As of the effective date of the 2020 Plan, shares available for grant under the 2010 Plan are available for grant under the 2020 Plan. In addition, our stockholders approved an additional 1,450,000 shares of common stock for issuance through the 2020 Plan. Options to purchase shares are granted at not less than 100% of the fair market value closing price on the date of grant, become exercisable at such time or times as determined when granted and expire not more than ten years after the date of grant.
At December 31, 2020, we had a total of 4,333,710 shares of our common stock available for future awards. In the event of a change in control of the Company, the terms of the awards under the 2020 Plan contain provisions that may cause restrictions to lapse and accelerate the vesting of awards.
2010 Long-Term Incentive Plan of BWX Technologies, Inc.
Members of the Board of Directors, executive officers, key employees and consultants were eligible to participate in the 2010 Plan prior to it being succeeded by the 2020 Plan. The Compensation Committee of the Board of Directors selected the participants for the 2010 Plan. The 2010 Plan provided for a number of forms of stock-based compensation, including incentive and non-qualified stock options, restricted stock, restricted stock units, performance shares and performance units, subject to satisfaction of specific performance goals. Shares subject to award under the 2010 Plan that are cancelled, forfeited, terminated or expire unexercised, shall immediately become available for the granting of awards under the 2020 Plan. As part of the approval of the 2010 Plan, 10,000,000 shares of common stock were initially authorized for issuance, with an additional 2,300,000 authorized for issuance in 2014. Options to purchase shares are granted at not less than 100% of the fair market value closing price on the date of grant, become exercisable at such time or times as determined when granted and expire not more than ten years after the date of grant.
Long-Term Incentive Plan of BWXT Technical Services Group, Inc.
In June 2012, we established the 2012 Long-Term Incentive Plan of BWXT Technical Services Group, Inc., a cash-settled plan for employees of certain subsidiaries and unconsolidated affiliates as selected by the plan committee. The cash-
78

Table of Contents
settled plan provides for a number of forms of stock-based compensation, including stock appreciation rights, restricted stock units and performance units, subject to satisfaction of specific performance goals. Stock appreciation rights are granted at not less than 100% of the fair market value closing price of a share of BWXT common stock on the date of grant, become exercisable at such time or times as determined when granted and expire not more than ten years after the date of grant. Stock appreciation rights are cash settled for the excess of the market price of BWXT common stock on the exercise date minus the exercise price. Restricted stock units and performance units are cash settled upon vesting as determined when granted. We will not issue any shares of BWXT common stock under this plan, as all awards are cash settled.
In the event of a change in control of the Company, the terms of the awards under the cash-settled plan contain provisions that may cause restrictions to lapse and accelerate the vesting of awards.
Stock-based compensation expense for all of our plans recognized for the years ended December 31, 2020, 2019 and 2018 totaled $16.8 million, $14.8 million and $10.8 million, respectively, with associated tax benefit totaling $2.7 million, $2.5 million and $1.7 million, respectively.
As of December 31, 2020, unrecognized estimated compensation expense related to nonvested awards was $15.1 million, which is expected to be recognized over a weighted-average period of 1.6 years.
Stock Options
The following table summarizes activity for our stock options for the year ended December 31, 2020 (share data in thousands):

|  | Number of Shares |  | Weighted- Average Exercise Price |  | Weighted- Average Remaining Contractual Term |  | Aggregate Intrinsic Value (In millions)
Outstanding at beginning of period |  | 324 |  |  | $ | 23.91 |  |  |  |  |

Exercisable at end of period |  | 201 |  |  | $ | 24.07 |  |  | 2.9 years |  | $ | 7.3 |

The aggregate intrinsic value included in the table above represents the total pre-tax intrinsic value that would have been received by the option holders had all option holders exercised their options on December 31, 2020. The intrinsic value is calculated as the total number of option shares multiplied by the difference between the closing price of our common stock on the last trading day of the period and the exercise price of the options. This amount changes based on the price of our common stock.
During the years ended December 31, 2020, 2019 and 2018, the total intrinsic value of stock options exercised was $4.7 million, $8.1 million and $8.5 million, respectively. The actual tax benefits realized related to the stock options exercised during the year ended December 31, 2020 totaled $0.8 million.

Table of Contents
The aggregate intrinsic value included in the table above represents the total pre-tax intrinsic value that would have been received by the stock appreciation rights holders had all holders exercised their rights on December 31, 2020. The intrinsic value is calculated as the total number of stock appreciation rights multiplied by the difference between the closing price of our common stock on the last trading day of the period and the exercise price of the stock appreciation rights. This amount changes based on the price of our common stock.
Cash-Settled Performance Units
The actual number of units in which each participant vests is dependent upon achievement of certain return on invested capital and diluted earnings per share targets over a three-year performance period. The number of units in which participants can vest ranges from zero to 200% of the initial performance units granted, to be determined upon completion of the three-year performance period.
As of December 31, 2020, we had 3,453 nonvested units valued at $60.28 per share with an assumed weighted-average vesting of 104%. The fair value is based on our closing stock price as of December 31, 2020 and is re-determined at the end of each reporting period for purposes of remeasuring compensation expense associated with these cash-settled awards.
Cash-Settled Restricted Stock Units
As of December 31, 2020, we had 1,422 nonvested units valued at $60.28 per share. The fair value is based on our closing stock price as of December 31, 2020 and is re-determined at the end of each reporting period for purposes of remeasuring compensation expense associated with these cash-settled awards.
NOTE 10 – COMMITMENTS AND CONTINGENCIES
Investigations and Litigation
Due to the nature of our business, we are, from time to time, involved in investigations, litigation, disputes or claims related to our business activities, including, among other things:
•performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and
•workers' compensation, employment, premises liability and other claims.
Based upon our prior experience, we do not expect that any of these litigation proceedings, disputes and claims will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.
Environmental Matters
We have been identified as a potentially responsible party at various cleanup sites under the Comprehensive Environmental Response, Compensation, and Liability Act, as amended ("CERCLA") and other environmental laws. These laws can impose liability for the entire cost of cleanup on any of the potentially responsible parties, regardless of fault or the lawfulness of the original conduct. Generally, however, where there are multiple responsible parties, a final allocation of costs is made based on the amount and type of wastes disposed of by each party and the number of financially viable parties, although this may not be the case with respect to any particular site. We have not been determined to be a major contributor of wastes to any of these sites. On the basis of the relative contribution of waste to each site by potentially responsible parties, as well as the financial solvency of other potentially responsible parties, we expect our share of the ultimate liability for the various sites will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows in any given year.
We perform significant amounts of work for the U.S. Government under both prime contracts and subcontracts and operate certain facilities that are licensed to possess and process special nuclear materials. As a result of these activities, we are subject to continuing reviews by governmental agencies, including the U.S. Environmental Protection Agency and the NRC. We are also involved in manufacturing activities at licensed facilities in Canada that are also subject to continuing reviews by governmental agencies in Canada, including the CNSC.
The NRC's decommissioning regulations require our Nuclear Operations Group segment to provide financial assurance that it will be able to pay the expected cost of decommissioning its two licensed facilities at the end of their service lives. We provided financial assurance totaling $61.8 million during the years ended December 31, 2020 and 2019 with surety bonds for
81

Table of Contents
the ultimate decommissioning of these licensed facilities. These facilities have provisions in their government contracts pursuant to which substantially all of our decommissioning costs and financial assurance obligations are covered by the DOE, including the costs to complete the decommissioning projects underway at the facility in Erwin, Tennessee. The surety bonds noted above are to cover decommissioning required pursuant to work not subject to this DOE obligation.
In Canada, the CNSC's decommissioning regulations require our Nuclear Power Group segment to provide financial assurance that it will be able to pay the expected cost of decommissioning its CNSC-licensed facilities at the end of their service lives. We provided financial assurance totaling $47.9 million and $47.0 million during the years ended December 31, 2020 and 2019, respectively, with letters of credit and surety bonds for the ultimate decommissioning of these licensed facilities.
Our compliance with federal, foreign, state and local environmental control and protection regulations resulted in pre-tax charges of approximately $16.3 million, $15.9 million and $14.7 million in the years ended December 31, 2020, 2019 and 2018, respectively. In addition, compliance with existing environmental regulations necessitated capital expenditures of $1.2 million, $1.4 million and $1.7 million in the years ended December 31, 2020, 2019 and 2018, respectively. At December 31, 2020 and 2019, we had total environmental accruals (including asset retirement obligations) of $91.3 million and $90.8 million, respectively. Of our total environmental accruals at December 31, 2020 and 2019, $7.1 million and $10.4 million, respectively, were included in current liabilities. Inherent in the estimates of these accruals are our expectations regarding the levels of contamination, decommissioning costs and recoverability from other parties, which may vary significantly as decommissioning activities progress. Accordingly, changes in estimates could result in material adjustments to our operating results, and the ultimate loss may differ materially from the amounts that we have provided for in our consolidated financial statements.
NOTE 11 – RISKS AND UNCERTAINTIES
Revenue Recognized Over Time
As of December 31, 2020, in accordance with the method of recognizing revenue over time, we have provided for our estimated costs to complete all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. The risk on fixed-price contracts is that revenue from the customer does not cover increases in our costs. It is possible that current estimates could materially change for various reasons, including, but not limited to, fluctuations in forecasted labor productivity or steel and other raw material prices. Increases in costs on our fixed-price contracts could have a material adverse impact on our consolidated financial condition, results of operations and cash flows. Alternatively, reductions in overall contract costs at completion could materially improve our consolidated financial condition, results of operations and cash flows.
Insurance
Upon the February 22, 2006 effectiveness of the settlement relating to the Chapter 11 proceedings involving several of our former subsidiaries, most of our subsidiaries contributed substantial insurance rights to the asbestos personal injury trust, including rights to (1) certain pre-1979 primary and excess insurance coverages and (2) certain of our 1979-1986 excess insurance coverage. These insurance rights provided coverage for, among other things, asbestos and other personal injury claims, subject to the terms and conditions of the policies. The contribution of these insurance rights was made in exchange for the agreement on the part of the representatives of the asbestos claimants, including the representative of future claimants, to the entry of a permanent injunction, pursuant to Section 524(g) of the U.S. Bankruptcy Code, to channel to the asbestos trust all asbestos-related general liability claims against our subsidiaries and former subsidiaries arising out of, resulting from or attributable to their operations, and the implementation of related releases and indemnification provisions protecting those subsidiaries and their affiliates from future liability for such claims. Although we are not aware of any significant, unresolved claims against our subsidiaries and former subsidiaries that are not subject to the channeling injunction and that relate to the periods during which such excess insurance coverage related, with the contribution of these insurance rights to the asbestos personal injury trust, it is possible that we could have underinsured or uninsured exposure for non-derivative asbestos claims or other personal injury or other claims that would have been insured under these coverages had the insurance rights not been contributed to the asbestos personal injury trust. In conjunction with the spin-off, claims and liabilities associated with the asbestos personal injury, property damage and indirect property damage claims mentioned above have been expressly assumed by BWE pursuant to the master separation agreement between us and BWE.
NOTE 12 – FINANCIAL INSTRUMENTS WITH CONCENTRATIONS OF CREDIT RISK
The primary customer of our Nuclear Operations Group and Nuclear Services Group segments is the U.S. Government, including some of its contractors. Our Nuclear Power Group segment's major customers are large utilities. These concentrations of customers may impact our overall exposure to credit risk, either positively or negatively, in that our customers may be
82

Table of Contents
similarly affected by changes in economic or other conditions. In the years ended December 31, 2020, 2019 and 2018, U.S. Government contracts accounted for approximately 77%, 77% and 79% of our total consolidated revenues, respectively. Accounts receivable due directly or indirectly from the U.S. Government represented 83% and 67% of net receivables at December 31, 2020 and 2019, respectively. See Note 15 for additional information about our operations in different geographic areas.
We believe that our provision for possible losses on uncollectable accounts receivable is adequate for our credit loss exposure. At December 31, 2020 and 2019, the allowances for possible losses that we deducted from Accounts receivable – trade, net on our consolidated balance sheets were $0.2 million.

NOTE 14 – FAIR VALUE MEASUREMENTS
FASB Topic Fair Value Measurements and Disclosures defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. This topic also sets forth the disclosure requirements regarding fair value and establishes a hierarchy for valuation inputs that emphasizes the use of observable inputs when measuring fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy established by this topic is as follows:
•Level 1 – inputs are based upon quoted prices for identical instruments traded in active markets.
•Level 2 – inputs are based upon quoted prices for similar instruments in active markets, quoted prices for similar or identical instruments in inactive markets and model-based valuation techniques for which all significant assumptions
83

Table of Contents
are observable in the market or can be corroborated by observable market data for substantially the full term of the assets and liabilities.
•Level 3 – inputs are generally unobservable and typically reflect management's estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar valuation techniques.
In accordance with FASB Topic Fair Value Measurements, certain investments that were measured at net asset value per share (or its equivalent) ("NAV") have not been classified in the fair value hierarchy. These investments are measured on the fair value of the underlying investments but may not be redeemable at that fair value. When appropriate, we adjust these net asset values for contributions and distributions, if any, made during the period beginning on the latest NAV valuation date and ending on our measurement date. We also consider available market data, relevant index returns, preliminary estimates from our investees and other data obtained through research and consultation with third-party advisors in determining the fair value of these investments.
The following sections describe the valuation methodologies we use to measure the fair values of our investments, derivatives and nonrecurring fair value measurements.
Investments
Investments primarily include U.S. Government and agency securities, corporate bonds and equities and mutual funds.
In general, and where applicable, we principally use a composite of observable prices and quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing methodology applies to our Level 1 and Level 2 investments.

Table of Contents
Derivatives
Level 2 derivative assets and liabilities currently consist of FX forward contracts. Where applicable, the value of these derivative assets and liabilities is computed by discounting the projected future cash flow amounts to present value using market-based observable inputs, including FX forward and spot rates, interest rates and counterparty performance risk adjustments. At December 31, 2020 and 2019, we had FX forward contracts outstanding to purchase or sell foreign currencies, primarily Canadian dollars and Euros, with a total fair value of $(2.2) million and $(0.8) million, respectively.
Other Financial Instruments
We used the following methods and assumptions in estimating our fair value disclosures for our other financial instruments, as follows:
Cash and cash equivalents and restricted cash and cash equivalents. The carrying amounts that we have reported in the accompanying consolidated balance sheets for Cash and cash equivalents and Restricted cash and cash equivalents approximate their fair values due to their highly liquid nature.
Long-term and short-term debt. We base the fair values of debt instruments, including our Senior Notes, on quoted market prices. Where quoted prices are not available, we base the fair values on the present value of future cash flows discounted at estimated borrowing rates for similar debt instruments or on estimated prices based on current yields for debt issues of similar quality and terms. At December 31, 2020 and 2019, the fair values of our Senior Notes due 2026 were $415.5 million and $423.5 million, respectively. At December 31, 2020, the fair value of our Senior Notes due 2028 was $416.7 million. The fair value of our remaining debt instruments approximated their carrying values at December 31, 2020 and 2019.
NOTE 15 – SEGMENT REPORTING
As described in Note 1, our operations are assessed based on three reportable segments. The operations of our segments are managed separately, and each segment has unique technology, services and customer classes. We account for intersegment
85

Table of Contents
sales at prices that we generally establish by reference to similar transactions with unaffiliated customers. Reportable segments are measured based on operating income exclusive of general corporate expenses and gains (losses) on sales of corporate assets.

Item 9A. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
As of the end of the period covered by this Report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) adopted by the SEC under the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Our disclosure controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. It should be noted that the design of any system of disclosure controls and procedures is based in part upon various assumptions about the likelihood of future events, and we cannot assure that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. Based on the evaluation referred to above, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of December 31, 2020 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and such information is accumulated and communicated to management, including its principal executives and principal financial officers or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
Management's Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as that term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) and for our assessment of the effectiveness of internal control over financial reporting.
Our internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of our consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and Board of Directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the consolidated 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.
Our management, including our Chief Executive Officer and Chief Financial Officer, has conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2020, based on the framework established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. This assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of those controls. Based on our assessment under the criteria described above, management has concluded that our internal control over financial reporting was effective as of December 31, 2020. Deloitte & Touche LLP has issued an attestation report on our internal control over financial reporting as of December 31, 2020, and their report is included in Item 9A.
Changes in Internal Control Over Financial Reporting
There has been no change in our internal control over financial reporting during the quarter ended December 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of BWX Technologies, Inc.:
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of BWX Technologies, Inc. and subsidiaries (the “Company”) as of December 31, 2020, 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, 2020, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020 of the Company and our report dated February 22, 2021 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.
