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, 2021 and 2020, 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, 2021, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2022 expressed an unqualified opinion on the Company's internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Revenue 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 reflect 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. 42 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. • We tested recorded revenue using analytical procedures. • We analyzed cumulative adjustments recorded during the year and tested those with characteristics of audit interest to determine that the adjustments were the result of changes in facts and circumstances. • We analyzed contracts with customers recognized over time to identify whether there are contracts with characteristics of audit interest. For each contract determined to exhibit characteristics of audit interest, we performed detail testing, including the following: ◦ Read the contract to understand the contract terms and 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 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: ▪ Evaluated costs incurred to date and costs of similar performance obligations, as appropriate, 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 manager and comparing the estimates to management’s work plans and/or supplier contracts, as appropriate. /S/ DELOITTE & TOUCHE LLP Charlotte, North Carolina February 22, 2022 We have served as the Company's auditor since 2009. 43 Table of Contents BWX TECHNOLOGIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2021 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, 2021 and for the year ended December 31, 2021. 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. 50 Table of Contents See Note 15 and Note 3 for financial information about our segments. During the first quarter of 2022, we made changes to our reportable segments to better align our businesses by their government and commercial nature, which reflects the manner in which resources will be allocated and operating performance will be assessed going forward. Beginning with first quarter of 2022 reporting, our reportable segments will be Government Operations and Commercial Operations, and both segments will now include research and development and certain commercialization activities associated with new technologies previously reported centrally, outside of our reportable segments. Our Government Operations segment will consist of our legacy Nuclear Operations Group and Nuclear Services Group segments with certain research and development activities in the areas of advanced reactors and autonomous manufacturing. Our Commercial Operations segment will consist of our legacy Nuclear Power Group with certain research and development and commercialization activities in the areas of medical and industrial radioisotopes. 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 There were no accounting standards adopted during the year ended December 31, 2021 that had an impact on our financial position, results of operations, cash flows or disclosures. 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. 51 Table of Contents The following summarizes the changes in the carrying amount of Accrued warranty expense: Year Ended December 31, 2021 2020 2019 (In thousands) Balance at beginning of period $ 5,292 $ 9,042 $ 10,344 Additions 924 1,341 2,232 Expirations and other changes (1) ( 424 ) ( 1,624 ) ( 2,728 ) Payments ( 605 ) ( 1,026 ) ( 1,065 ) Translation and other (2) 134 ( 2,441 ) 259 Balance at end of period $ 5,321 $ 5,292 $ 9,042 (1) Includes discounts provided to customers in satisfaction of warranty obligations totaling $( 1.2 ) million in the year ended December 31, 2019. (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. 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 years ended December 31, 2021 and 2020, we recognized subsidies under the CEWS as offsets to operating expenses of $ 5.4 million and $ 20.4 million, respectively. 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. Research and development activities totaled $ 31.4 million, $ 40.8 million and $ 66.9 million in the years ended December 31, 2021, 2020 and 2019, respectively. This includes amounts paid for by our customers of $ 20.3 million, $ 26.6 million and $ 49.2 million, in the years ended December 31, 2021, 2020 and 2019, respectively. 52 Table of Contents Capitalization of Interest Cost We capitalize interest in accordance with FASB Topic Interest . We incurred total interest of $ 51.1 million, $ 40.8 million and $ 41.4 million in the years ended December 31, 2021, 2020 and 2019, respectively, of which we capitalized $ 15.3 million, $ 9.8 million and $ 6.1 million in the years ended December 31, 2021, 2020 and 2019, 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, 2021, we had restricted cash and cash equivalents totaling $ 5.9 million, $ 3.0 million of which was held for future decommissioning of facilities (which is included in Other Assets on our consolidated balance sheets) and $ 2.9 million of which was held to meet reinsurance reserve requirements of our captive insurer. The following table provides a reconciliation of cash and cash equivalents and restricted cash and cash equivalents on our consolidated balance sheets to the totals presented on our consolidated statements of cash flows: December 31, 2021 2020 (In thousands) Cash and cash equivalents $ 33,891 $ 42,610 Restricted cash and cash equivalents 2,896 3,070 Restricted cash and cash equivalents included in Other Assets 2,988 2,618 Total cash and cash equivalents and restricted cash and cash equivalents as presented on our consolidated statements of cash flows $ 39,775 $ 48,298 Investments Our investment portfolio consists primarily of U.S. Government 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 53 Table of Contents 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 investments 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, 2021 and 2020, Other current assets included inventories totaling $ 16.3 million and $ 15.0 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 $ 58.1 million, $ 50.3 million and $ 51.0 million for the years ended December 31, 2021, 2020 and 2019, 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. Property, plant and equipment is stated at cost and is set forth below: December 31, 2021 2020 (In thousands) Land $ 9,538 $ 9,585 Buildings 321,872 267,808 Machinery and equipment 957,423 827,785 Property under construction 487,856 420,374 1,776,689 1,525,552 Less: Accumulated depreciation 731,049 709,081 Property, Plant and Equipment, Net $ 1,045,640 $ 816,471 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 or more frequently whenever events or circumstances indicate the carrying value of goodwill may be impaired. 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 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. 54 Table of Contents The following summarizes the changes in the carrying amount of Goodwill: Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total (In thousands) Balance at December 31, 2019 $ 110,939 $ 119,563 $ 45,000 $ 275,502 Acquisition of Precision Manufacturing (Note 2) — 5,753 — 5,753 Translation — 2,453 — 2,453 Balance at December 31, 2020 $ 110,939 $ 127,769 $ 45,000 $ 283,708 Translation — 1,794 — 1,794 Balance at December 31, 2021 $ 110,939 $ 129,563 $ 45,000 $ 285,502 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. 55 Table of Contents Our Intangible Assets were as follows: December 31, 2021 2020 2019 (In thousands) Amortized intangible assets: Gross cost: Technical support agreement $ 69,781 $ 68,785 $ 67,423 Customer relationships 40,247 39,954 39,555 Unpatented technology 38,073 37,529 36,785 CNSC class 1B nuclear facility license 26,911 26,528 26,002 Acquired backlog 7,595 7,487 — Patented technology 792 780 765 All other 871 858 2,200 Total $ 184,270 $ 181,921 $ 172,730 Accumulated amortization: Technical support agreement $ ( 10,366 ) $ ( 7,227 ) $ ( 4,153 ) Customer relationships ( 18,176 ) ( 15,996 ) ( 13,841 ) Unpatented technology ( 6,398 ) ( 4,584 ) ( 2,805 ) CNSC class 1B nuclear facility license ( 4,521 ) ( 3,573 ) ( 2,635 ) Acquired backlog ( 2,531 ) ( 1,248 ) — Patented technology ( 363 ) ( 286 ) ( 212 ) All other ( 194 ) ( 86 ) ( 1,522 ) Total $ ( 42,549 ) $ ( 33,000 ) $ ( 25,168 ) Net amortized intangible assets $ 141,721 $ 148,921 $ 147,562 Unamortized intangible assets: NRC category 1 license $ 43,830 $ 43,830 $ 43,830 The following summarizes the changes in the carrying amount of Intangible Assets: Year Ended December 31, 2021 2020 2019 (In thousands) Balance at beginning of period $ 192,751 $ 191,392 $ 228,676 Acquisitions (Note 2) — 8,180 — Amortization expense ( 9,329 ) ( 8,824 ) ( 9,128 ) Reclassification of right-of-use assets — — ( 33,866 ) Translation and other (1) 2,129 2,003 5,710 Balance at end of period $ 185,551 $ 192,751 $ 191,392 (1) Includes $( 0.6 ) million related to the divestiture of the U.S.-based commercial nuclear services business during the year ended December 31, 2020. Estimated amortization expense for the next five fiscal years is as follows (amounts in thousands): Year Ended December 31, Amount 2022 $ 9,257 2023 $ 9,257 2024 $ 9,257 2025 $ 9,257 2026 $ 7,991 56 Table of Contents 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 sheets. Our current lease liabilities are included in Accrued liabilities – other , and our noncurrent lease liabilities are included in Other Liabilities on our consolidated balance sheets. 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, 2021, we recognized lease expense of $ 8.4 million, which included $ 1.7 million related to the amortization of favorable lease agreements, and paid cash of $ 6.7 million for our operating leases. During the years ended December 31, 2020 and 2019, we recognized lease expense of $ 7.7 million and $ 8.1 million, respectively. At December 31, 2021, our weighted-average remaining lease term was 6.7 years, and for the purpose of measuring the present value of our lease liabilities, the weighted-average discount rate was 4.19 %. The maturities of our lease liabilities at December 31, 2021 were as follows (amounts in thousands): 2022 $ 3,979 2023 2,664 2024 2,225 2025 1,849 2026 1,831 Thereafter 5,025 Total lease payments $ 17,573 Less: Interest ( 2,445 ) Present value of lease liabilities (1) $ 15,128 (1) Includes current lease liabilities of $ 3.9 million. At December 31, 2021, our right-of-use assets totaled $ 46.4 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 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, 2021 2020 2019 (In thousands) Balance at beginning of period $ 12,269 $ 8,006 $ 9,583 Additions 4,838 6,803 — Interest expense (1) ( 6,411 ) ( 2,540 ) ( 1,577 ) Balance at end of period $ 10,696 $ 12,269 $ 8,006 (1) Includes the recognition of prior deferred debt issuance costs associated with former debt instruments of $( 4.2 ) million and $( 0.7 ) million for the years ended December 31, 2021 and 2020, 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 comprising 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 57 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, 2021 2020 2019 (In thousands) Balance at beginning of period $ 78,110 $ 77,288 $ 90,822 Costs incurred ( 215 ) ( 1,608 ) ( 10,380 ) Additions/adjustments — ( 3,284 ) ( 5,030 ) Acquisitions — — — Accretion 5,996 5,343 5,379 Translation and other (1) 241 371 ( 3,503 ) Balance at end of period (2) $ 84,132 $ 78,110 $ 77,288 (1) Includes an adjustment of $( 4.3 ) million to correct the business combination accounting for our 2016 acquisition during the year ended December 31, 2019. (2) Includes current asset retirement obligations of $ 4.7 million, $ 2.8 million and $ 5.7 million at December 31, 2021, 2020 and 2019, respectively. 58 Table of Contents 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 $ 4.5 million and $ 5.0 million at December 31, 2021 and 2020, 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. Accumulated Other Comprehensive Income The components of Accumulated other comprehensive income included in Stockholders' Equity are as follows: December 31, 2021 2020 (In thousands) Currency translation adjustments $ 30,627 $ 24,454 Net unrealized loss on derivative financial instruments ( 694 ) ( 496 ) Unrecognized prior service cost on benefit obligations ( 18,022 ) ( 15,902 ) Net unrealized gain on available-for-sale investments 232 142 Accumulated other comprehensive income $ 12,143 $ 8,198 The amounts reclassified out of Accumulated other comprehensive income by component and the affected consolidated statements of income line items are as follows: Year Ended December 31, 2021 2020 2019 Accumulated Other Comprehensive Income (Loss) Component Recognized (In thousands) Line Item Presented Realized (loss) gain on derivative financial instruments $ 307 $ ( 35 ) $ ( 132 ) Revenues ( 712 ) 695 ( 1,066 ) Cost of operations ( 405 ) 660 ( 1,198 ) Total before tax 103 ( 173 ) 310 Provision for Income Taxes $ ( 302 ) $ 487 $ ( 888 ) Net Income Amortization of prior service cost on benefit obligations $ ( 2,919 ) $ ( 3,177 ) $ ( 2,592 ) Other – net 624 645 562 Provision for Income Taxes $ ( 2,295 ) $ ( 2,532 ) $ ( 2,030 ) Net Income Total reclassification for the period $ ( 2,597 ) $ ( 2,045 ) $ ( 2,918 ) 59 Table of Contents 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 $ 1.8 million, $( 0.6 ) million and $ 1.0 million for the years ended December 31, 2021, 2020 and 2019, 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, 2021, we had deferred approximately $( 0.7 ) 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, 2021, 2020 and 2019, we recognized $( 0.1 ) million, $ 8.7 million and $( 1.0 ) million, respectively, of (gains) losses associated with FX forward contracts not designated as hedging instruments. At December 31, 2021, our derivative financial instruments consisted of FX forward contracts with a total notional value of $ 352.2 million with maturities extending to November 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. New Accounting Standards In October 2021, the FASB issued an update to the Topic Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This update requires entities to recognize and measure contract assets and liabilities acquired in a business combination in accordance with FASB Topic Revenue from Contracts with Customers . The update will generally result in an entity recognizing contract assets and liabilities at amounts consistent with those recorded by the acquiree immediately before the acquisition date rather than at fair value. The new standard is effective on a prospective basis for fiscal years beginning after December 15, 2022, with early adoption permitted. We are currently evaluating the impact, if any, of the adoption of this standard on our financial statements. NOTE 2 – ACQUISITIONS Laker Energy Products Ltd. On January 2, 2020, our subsidiary BWXT Canada Ltd. acquired Laker Energy Products Ltd., which was renamed BWXT Precision Manufacturing Inc. ("Precision Manufacturing"), for CAD 23.3 million ($ 17.8 million U.S. dollar equivalent). We were subject to the payment of contingent consideration of which we had 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 60 Table of Contents liabilities of $ 2.7 million. During the year ended December 31, 2021, we entered into an agreement with the seller resulting in no contingent consideration due and recognized a gain of $ 2.0 million (CAD 2.5 million) as a component of Cost of operations. Precision Manufacturing is a global supplier of nuclear-grade materials and precisely machined components for CANDU nuclear power utilities and is reported as part of our Nuclear Power Group segment. NOTE 3 – REVENUE RECOGNITION 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 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. 61 Table of Contents Disaggregated Revenues We allocate geographic revenues based on the location of the customers' operations. Revenues by geographic area and customer type were as follows: Year Ended December 31, 2021 Year Ended December 31, 2020 Year Ended December 31, 2019 Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total (In thousands) United States: Government $ 1,527,704 $ — $ 114,465 $ 1,642,169 $ 1,540,256 $ — $ 113,075 $ 1,653,331 $ 1,368,555 $ — $ 111,236 $ 1,479,791 Non-Government 87,809 44,102 5,560 137,471 98,986 35,432 19,061 153,479 51,802 38,058 17,907 107,767 $ 1,615,513 $ 44,102 $ 120,025 $ 1,779,640 $ 1,639,242 $ 35,432 $ 132,136 $ 1,806,810 $ 1,420,357 $ 38,058 $ 129,143 $ 1,587,558 Canada: Non-Government $ — $ 345,412 $ 3,417 $ 348,829 $ — $ 309,433 $ 4,357 $ 313,790 $ — $ 287,948 $ 2,196 $ 290,144 Other: Non-Government $ 7,085 $ 17,568 $ 96 $ 24,749 $ 7,015 $ 26,404 $ — $ 33,419 $ 8,230 $ 26,634 $ — $ 34,864 Segment Revenues $ 1,622,598 $ 407,082 $ 123,538 2,153,218 $ 1,646,257 $ 371,269 $ 136,493 2,154,019 $ 1,428,587 $ 352,640 $ 131,339 1,912,566 Eliminations ( 29,144 ) ( 30,503 ) ( 17,646 ) Revenues $ 2,124,074 $ 2,123,516 $ 1,894,920 Revenues by timing of transfer of goods or services were as follows: Year Ended December 31, 2021 Year Ended December 31, 2020 Year Ended December 31, 2019 Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total (In thousands) (In thousands) (In thousands) Over time $ 1,622,462 $ 355,477 $ 123,538 $ 2,101,477 $ 1,646,092 $ 322,745 $ 136,493 $ 2,105,330 $ 1,428,348 $ 305,075 $ 131,339 $ 1,864,762 Point-in-time 136 51,605 — 51,741 165 48,524 — 48,689 239 47,565 — 47,804 Segment Revenues $ 1,622,598 $ 407,082 $ 123,538 2,153,218 $ 1,646,257 $ 371,269 $ 136,493 2,154,019 $ 1,428,587 $ 352,640 $ 131,339 1,912,566 Eliminations ( 29,144 ) ( 30,503 ) ( 17,646 ) Revenues $ 2,124,074 $ 2,123,516 $ 1,894,920 Revenues by contract type were as follows: Year Ended December 31, 2021 Year Ended December 31, 2020 Year Ended December 31, 2019 Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total Nuclear Operations Group Nuclear Power Group Nuclear Services Group Total (In thousands) (In thousands) (In thousands) Fixed-Price Incentive Fee $ 1,244,916 $ 9,279 $ — $ 1,254,195 $ 1,226,770 $ 1,578 $ — $ 1,228,348 $ 1,137,883 $ 2,511 $ — $ 1,140,394 Firm-Fixed-Price 271,656 307,200 38,151 617,007 306,296 296,394 32,334 635,024 210,631 282,014 26,163 518,808 Cost-Plus Fee 104,365 — 73,621 177,986 112,479 — 94,320 206,799 79,741 755 102,726 183,222 Time-and-Materials 1,661 90,603 11,766 104,030 712 73,297 9,839 83,848 332 67,360 2,450 70,142 Segment Revenues $ 1,622,598 $ 407,082 $ 123,538 2,153,218 $ 1,646,257 $ 371,269 $ 136,493 2,154,019 $ 1,428,587 $ 352,640 $ 131,339 1,912,566 Eliminations ( 29,144 ) ( 30,503 ) ( 17,646 ) Revenues $ 2,124,074 $ 2,123,516 $ 1,894,920 62 Table of Contents 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, 2021, 2020 and 2019, we recognized net favorable changes in estimates that resulted in increases in revenues of $ 30.7 million, $ 44.9 million and $ 70.9 million, respectively, as well as increases (decreases) in cost of operations of $ 4.2 million, $ 2.1 million and $( 0.7 ) million, respectively. 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 receivables. 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, 2021, our unbilled receivables increased $ 92.4 million primarily as a result of fixed-price incentive fee contracts within our Nuclear Operations Group segment and the timing of milestone billings on certain firm-fixed-price contracts within our Nuclear Power Group segment. During the year ended December 31, 2021, our Advance billings on contracts increased $ 28.0 million primarily as a result of billings in excess of revenue recognized on certain firm-fixed-price contracts within our Nuclear Operations Group segment. 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. December 31, December 31, 2021 2020 (In thousands) Included in Contracts in progress: Unbilled receivables $ 528,644 $ 436,279 Retainages $ 51,507 $ 55,172 Included in Other Assets: Retainages $ 1,271 $ 1,488 Advance billings on contracts $ 111,619 $ 83,581 Retainages expected to be collected after one year are included in Other Assets. Of the long-term retainages at December 31, 2021, we anticipate collecting $ 0.3 million in 2023 and $ 1.0 million in 2024. During the years ended December 31, 2021 and 2020, we recognized $ 67.5 million and $ 51.5 million of revenue that was in Advance billings on contracts at the beginning of each year, respectively. Remaining Performance Obligations Remaining performance obligations represent the dollar amount of revenue we expect to recognize in the future from performance obligations on contracts previously awarded and in progress. Of the remaining performance obligations on our contracts with customers at December 31, 2021, we expect to recognize revenues as follows: 2022 2023 Thereafter Total (In approximate millions) Nuclear Operations Group $ 1,573 $ 1,102 $ 1,836 $ 4,511 Nuclear Power Group 260 142 242 644 Nuclear Services Group 21 — — 21 Total Remaining Performance Obligations $ 1,854 $ 1,244 $ 2,078 $ 5,176 63 Table of Contents NOTE 4 – EQUITY METHOD INVESTMENTS We have investments in entities that we account for using the equity method.

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 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.

We believe that our remaining deferred tax assets are more likely than not realizable through carrybacks, future reversals of existing taxable temporary differences, our estimate of future taxable income and potential tax planning. 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: Beginning Balance Charges To Costs and Expenses Charged To Other Accounts Ending Balance (In thousands) Year Ended December 31, 2021 $ ( 12,892 ) ( 326 ) — $ ( 13,218 ) Year Ended December 31, 2020 $ ( 13,578 ) 771 ( 85 ) $ ( 12,892 ) Year Ended December 31, 2019 $ ( 13,257 ) ( 414 ) 93 $ ( 13,578 ) We have domestic federal and foreign capital losses of $ 9.3 million available to offset future capital gains. The domestic federal capital losses begin to expire in 2023, while the foreign capital losses have an indefinite carryforward period. We are carrying a full valuation allowance of $ 9.3 million against the deferred tax asset related to these domestic federal and foreign capital loss carryforwards. In addition, we have state credits and state net operating losses of $ 6.1 million ($ 4.9 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 2022. We are carrying a valuation allowance of $ 4.9 million ($ 3.9 million net of federal tax benefit) against the deferred tax asset related to the state credits and state loss carryforwards. 67 Table of Contents We would be subject to withholding taxes if we were to distribute earnings from certain foreign subsidiaries. As of December 31, 2021, the undistributed earnings of these subsidiaries were approximately $ 248.9 million, and our unrecognized deferred income tax liabilities of approximately $ 12.4 million would be payable upon the distribution of these earnings. All of our foreign earnings are considered indefinitely reinvested. NOTE 6 – LONG-TERM DEBT Our Long-Term Debt consists of the following: December 31, 2021 2020 (In thousands) Debt Instruments: Senior Notes $ 800,000 $ 800,000 Credit Facility 400,000 75,000 Long-Term Debt, gross 1,200,000 875,000 Less: Deferred debt issuance costs 10,696 12,269 Long-Term Debt $ 1,189,304 $ 862,731 Maturities of Long-Term Debt subsequent to December 31, 2021 were as follows: 2022 through 2024 – $ 0.0 million ; 2025 – $ 400.0 million; 2026 – $ 0.0 million ; and thereafter – $ 800.0 million. Credit Facility On March 24, 2020, we entered into an Amendment No. 1 to Credit Agreement, which amended the Credit Agreement dated as of May 24, 2018 (as amended, the "Credit Facility") with Wells Fargo Bank, N.A., as administrative agent, and the other lenders party thereto. The Credit Facility provides for a $ 750 million senior secured revolving credit facility (the "Revolving Credit Facility"). 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, 2021, 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 68 Table of Contents 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, 2021, the margin for Eurocurrency rate and base rate revolving loans was 1.50 % and 0.50 %, respectively, the letter of credit fee for financial letters of credit and performance letters of credit was 1.50 % and 0.90 %, respectively, and the commitment fee for the unused portion of the Revolving Credit Facility was 0.20 %. As of December 31, 2021, borrowings and letters of credit issued under the Revolving Credit Facility totaled $ 400.0 million and $ 36.2 million, respectively. As a result, as of December 31, 2021 we had $ 313.8 million available under the Revolving Credit Facility for borrowings and to meet letter of credit requirements. As of December 31, 2021, the interest rate on outstanding borrowings under our Credit Facility was 1.61 %. 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 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, among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank National Association, as trustee. On July 15, 2021, using cash on hand and borrowings under the Credit Facility, we redeemed the Senior Notes due 2026 at a redemption price equal to 102.688 % of the principal amount, resulting in an early redemption premium of $ 10.8 million and the write-off of deferred debt issuance costs totaling $ 4.2 million.

The 2020 Indenture contains customary events of default, including, among other things, payment default, failure to comply with covenants or agreements contained in the 2020 Indenture or the Senior Notes due 2028 and certain provisions related to bankruptcy events. The 2020 Indenture also contains customary negative covenants. As of December 31, 2021, we were in compliance with all covenants set forth in the 2020 Indenture and the Senior Notes due 2028. 69 Table of Contents Senior Notes due 2029 We issued $ 400 million aggregate principal amount of 4.125 % senior notes due 2029 (the "Senior Notes due 2029") pursuant to an indenture dated April 13, 2021 (the "2021 Indenture"), among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank, as trustee.

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, 2021, bonds issued and outstanding under these arrangements totaled approximately $ 109.5 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, 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. 70 Table of Contents Obligations and Funded Status Pension Benefits Year Ended December 31, Other Benefits Year Ended December 31, 2021 2020 2021 2020 (In thousands) Change in benefit obligation: Benefit obligation at beginning of period $ 1,414,055 $ 1,308,798 $ 61,086 $ 58,881 Service cost 11,667 10,650 760 642 Interest cost 27,170 37,199 1,197 1,612 Plan participants' contributions 199 180 488 562 Amendments 2,314 2,333 3,402 — Settlements ( 38,330 ) ( 7,041 ) — — Actuarial loss (gain) ( 45,476 ) 120,126 ( 4,944 ) 2,219 Foreign currency exchange rate changes 1,669 3,513 197 331 Benefits paid ( 65,002 ) ( 61,703 ) ( 2,885 ) ( 3,161 ) Benefit obligation at end of period $ 1,308,266 $ 1,414,055 $ 59,301 $ 61,086 Change in plan assets: Fair value of plan assets at beginning of period $ 1,281,232 $ 1,150,495 $ 52,077 $ 48,321 Actual return on plan assets 72,030 190,862 2,898 5,293 Plan participants' contributions 199 180 488 562 Company contributions 6,164 5,131 1,008 992 Settlements ( 39,439 ) ( 7,041 ) — — Foreign currency exchange rate changes 1,615 3,308 — — Benefits paid ( 65,002 ) ( 61,703 ) ( 2,959 ) ( 3,091 ) Fair value of plan assets at the end of period 1,256,799 1,281,232 53,512 52,077 Funded status $ ( 51,467 ) $ ( 132,823 ) $ ( 5,789 ) $ ( 9,009 ) Amounts recognized in the balance sheet consist of: Prepaid postretirement benefit obligation $ — $ — $ 20,122 $ 18,069 Prepaid pension 10,573 14,588 — — Accrued employee benefits ( 3,125 ) ( 3,082 ) ( 1,578 ) ( 1,389 ) Accumulated postretirement benefit obligation — — ( 24,333 ) ( 25,689 ) Pension liability ( 58,915 ) ( 144,329 ) — — Accrued benefit liability, net $ ( 51,467 ) $ ( 132,823 ) $ ( 5,789 ) $ ( 9,009 ) Amount recognized in accumulated comprehensive income (before taxes): Prior service cost (credit) $ 20,536 $ 21,319 $ 2,520 $ ( 1,059 ) Supplemental information: Plans with accumulated benefit obligation in excess of plan assets: Projected benefit obligation $ 1,172,881 $ 1,264,764 N/A N/A Accumulated benefit obligation $ 1,166,855 $ 1,255,899 $ 23,503 $ 24,593 Fair value of plan assets $ 1,110,841 $ 1,117,353 $ — $ — Plans with plan assets in excess of accumulated benefit obligation: Projected benefit obligation $ 135,385 $ 149,291 N/A N/A Accumulated benefit obligation $ 135,375 $ 149,270 $ 35,798 $ 36,493 Fair value of plan assets $ 145,958 $ 163,879 $ 53,512 $ 52,077 71 Table of Contents We record the service cost component of net periodic benefit cost within Operating income on our consolidated statements of income. For the years ended December 31, 2021, 2020 and 2019, these amounts were $ 12.4 million, $ 11.3 million and $ 9.7 million, respectively. All other components of net periodic benefit cost are included in Other – net on our consolidated statements of income. For the years ended December 31, 2021, 2020 and 2019, these amounts were $( 92.9 ) million, $( 31.6 ) million and $( 17.5 ) million, respectively.

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 under the heading "Critical Accounting Estimates" 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, 2021 and 2020 increased (decreased) by $( 43.0 ) million and $ 124.2 million, respectively, due to changes in the discount rate. In December 2021, we purchased a group annuity contract that transferred certain foreign hourly pension benefit obligations of approximately $ 38.3 million to an insurance company for approximately 400 retirees. As a result, we recognized pension settlement-related charges of $ 1.1 million during the year ended December 31, 2021. Additional Information Pension Benefits Year Ended December 31, Other Benefits Year Ended December 31, 2021 2020 2021 2020 (In thousands) Decrease in accumulated other comprehensive income due to actuarial losses – before taxes $ ( 2,314 ) $ ( 2,333 ) $ ( 3,402 ) $ — In the current fiscal year, we have recognized expense (income) in other comprehensive income as a component of net periodic benefit cost of approximately $ 3.1 million and $( 0.2 ) million for our pension benefits and other benefits, respectively. 72 Table of Contents Assumptions Pension Benefits Other Benefits 2021 2020 2021 2020 Weighted-average assumptions used to determine net periodic benefit obligations at December 31: Discount rate 2.91 % 2.63 % 2.85 % 2.49 % Pension Benefits Other Benefits 2021 2020 2019 2021 2020 2019 Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31: Discount rate to determine interest cost 1.96 % 2.78 % 3.98 % 1.87 % 2.62 % 3.92 % Expected return on plan assets 6.80 % 6.95 % 6.95 % 5.66 % 5.66 % 5.68 % 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. 2021 2020 Assumed health care cost trend rates at December 31: Health care cost trend rate assumed for next year 7.50 % 6.75 % Rates to which the cost trend rate is assumed to decline (ultimate trend rate) 4.50 % 4.50 % Year that the rate reaches ultimate trend rate 2034 2030 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. 73 Table of Contents Domestic Plans We sponsor the following domestic defined benefit pension plans: • BWXT Retirement Plan; • Nuclear Fuel Services, Inc. Retirement Plan for Salaried Employees; and • Nuclear Fuel Services, Inc. Retirement Plan for Hourly Employees. The assets of the domestic pension plans are commingled for investment purposes and held by the trustee in the BWXT Master Trust (the "Master Trust"). For the years ended December 31, 2021 and 2020, the investment returns on domestic plan assets of the Master Trust (net of deductions for management fees) were approximately 9 % and 19 %, respectively.

(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, 2021, we had a total of 4,036,598 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 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.

The cash-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, 2021, 2020 and 2019 totaled $ 18.3 million, $ 16.8 million and $ 14.8 million, respectively, with associated tax benefit totaling $ 3.0 million, $ 2.7 million and $ 2.5 million, respectively. As of December 31, 2021, unrecognized estimated compensation expense related to nonvested awards was $ 14.8 million, which is expected to be recognized over a weighted-average period of 1.6 years. 77 Table of Contents Stock Options The following table summarizes activity for our stock options for the year ended December 31, 2021 (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 201 $ 24.07 Granted — N/A Exercised ( 76 ) $ 24.77 Cancelled/expired/forfeited — N/A Outstanding at end of period 125 $ 23.65 3.2 years $ 3.0 Exercisable at end of period 125 $ 23.65 3.2 years $ 3.0 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, 2021. 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, 2021, 2020 and 2019, the total intrinsic value of stock options exercised was $ 2.7 million, $ 4.7 million and $ 8.1 million, respectively. The actual tax benefits realized related to the stock options exercised during the year ended December 31, 2021 totaled $ 0.3 million. Performance Shares Nonvested performance shares as of December 31, 2021 and changes during the year ended December 31, 2021 were as follows (share data in thousands): Number of Shares Weighted- Average Grant Date Fair Value Nonvested at beginning of period 451 $ 56.15 Adjustment to assumed vesting percentage 52 $ 58.51 Granted 159 $ 59.39 Vested ( 104 ) $ 63.81 Cancelled/forfeited ( 13 ) $ 56.23 Nonvested at end of period 545 $ 55.90 The actual number of shares 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 shares in which participants can vest ranges from zero to 200 % of the initial performance shares granted, to be determined upon completion of the three -year performance period. The nonvested shares at the end of the period in the table above assumes weighted-average vesting of 129 %. The actual tax benefits realized related to the performance shares vested during the year ended December 31, 2021 totaled $ 1.0 million. 78 Table of Contents Restricted Stock Units Nonvested restricted stock units as of December 31, 2021 and changes during the year ended December 31, 2021 were as follows (share data in thousands): Number of Shares Weighted- Average Grant Date Fair Value Nonvested at beginning of period 185 $ 55.96 Granted 150 $ 60.29 Vested ( 107 ) $ 58.45 Cancelled/forfeited ( 7 ) $ 57.09 Nonvested at end of period 221 $ 57.66 The actual tax benefits realized related to the restricted stock units vested during the year ended December 31, 2021 totaled $ 1.1 million. Cash-Settled Stock Appreciation Rights The following table summarizes activity for our stock appreciation rights for the year ended December 31, 2021 (unit data in thousands): Number of Units Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term Aggregate Intrinsic Value (In millions) Outstanding at beginning of period 40 $ 24.04 Granted — N/A Exercised ( 13 ) $ 24.97 Cancelled/expired/forfeited — N/A Outstanding at end of period 27 $ 23.62 3.2 years $ 0.7 Exercisable at end of period 27 $ 23.62 3.2 years $ 0.7 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, 2021. 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, 2021, we had 3,973 nonvested units valued at $ 47.88 per share with an assumed weighted-average vesting of 128 %. The fair value is based on our closing stock price as of December 31, 2021 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, 2021, we had 1,715 nonvested units valued at $ 47.88 per share. The fair value is based on our closing stock price as of December 31, 2021 and is re-determined at the end of each reporting period for purposes of remeasuring compensation expense associated with these cash-settled awards. 79 Table of Contents 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 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, 2021 and 2020 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 $ 46.4 million and $ 47.9 million during the years ended December 31, 2021 and 2020, 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 $ 17.5 million, $ 16.3 million and $ 15.9 million in the years ended December 31, 2021, 2020 and 2019, respectively. In addition, compliance with existing environmental regulations necessitated capital expenditures of $ 3.1 million, $ 1.2 million and $ 1.4 million in the years ended December 31, 2021, 2020 and 2019, respectively. At December 31, 2021 and 2020, we had total environmental accruals (including asset retirement obligations) of $ 102.4 million and $ 91.3 million, respectively. Of our total environmental accruals at December 31, 2021 and 2020, $ 9.8 million and $ 7.1 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. 80 Table of Contents NOTE 11 – RISKS AND UNCERTAINTIES Revenue Recognized Over Time As of December 31, 2021, 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 similarly affected by changes in economic or other conditions. In the years ended December 31, 2021, 2020 and 2019, U.S. Government contracts accounted for approximately 76 %, 77 % and 77 % of our total consolidated revenues, respectively. Accounts receivable due directly or indirectly from the U.S. Government represented 68 % and 83 % of net receivables at December 31, 2021 and 2020, respectively. See Note 15 and Note 3 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, 2021 and 2020, the allowances for possible losses that we deducted from Accounts receivable – trade, net on our consolidated balance sheets were $ 0.2 million. 81 Table of Contents NOTE 13 – INVESTMENTS The following is a summary of our investments at December 31, 2021: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value (In thousands) Equity securities Mutual funds $ 6,001 $ 1,649 $ — $ 7,650 Available-for-sale securities U.S. Government and agency securities 2,742 — ( 4 ) 2,738 Corporate bonds 2,559 374 ( 7 ) 2,926 Asset-backed securities and collateralized mortgage obligations 107 — ( 52 ) 55 Total $ 11,409 $ 2,023 $ ( 63 ) $ 13,369 The following is a summary of our investments at December 31, 2020: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value (In thousands) Equity securities Equities $ 172 $ 628 $ — $ 800 Mutual funds 5,323 1,432 — 6,755 Available-for-sale securities U.S. Government and agency securities 2,317 1 ( 4 ) 2,314 Corporate bonds 2,879 259 ( 6 ) 3,132 Asset-backed securities and collateralized mortgage obligations 115 — ( 53 ) 62 Total $ 10,806 $ 2,320 $ ( 63 ) $ 13,063 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 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 82 Table of Contents 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 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. Fair Value Measurements The following is a summary of our investments measured at fair value at December 31, 2021: 12/31/2021 Level 1 Level 2 Level 3 Unclassified (In thousands) Equity securities Mutual funds $ 7,650 $ — $ 7,650 $ — $ — Available-for-sale securities U.S. Government and agency securities 2,738 2,738 — — — Corporate bonds 2,926 1,852 1,074 — — Asset-backed securities and collateralized mortgage obligations 55 — 55 — — Total $ 13,369 $ 4,590 $ 8,779 $ — $ — The following is a summary of our investments measured at fair value at December 31, 2020: 12/31/2020 Level 1 Level 2 Level 3 Unclassified (In thousands) Equity securities Equities $ 800 $ — $ — $ 800 $ — Mutual funds 6,755 — 6,755 — — Available-for-sale securities U.S. Government and agency securities 2,314 2,314 — — — Corporate bonds 3,132 1,738 1,394 — — Asset-backed securities and collateralized mortgage obligations 62 — 62 — — Total $ 13,063 $ 4,052 $ 8,211 $ 800 $ — 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, 2021 and 2020, we had FX forward contracts outstanding to purchase or sell foreign currencies, primarily Canadian dollars and Euros, with a total fair value of $( 3.2 ) million and $( 2.2 ) million, respectively. 83 Table of Contents Other Financial Instruments We used the following methods and assumptions in estimating our fair value disclosures for our other financial instruments: 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, the fair value of our Senior Notes due 2026 was $ 415.5 million. At December 31, 2021 and 2020, the fair value of our Senior Notes due 2028 was $ 406.3 million and $ 416.7 million, respectively. At December 31, 2021, the fair value of our Senior Notes due 2029 was $ 406.5 million. The fair value of our remaining debt instruments approximated their carrying values at December 31, 2021 and 2020. 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 84 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. 1.
