NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2020
(UNAUDITED)
NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
We have presented the condensed consolidated financial statements of BWX Technologies, Inc. ("BWXT" or the "Company") in U.S. dollars in accordance with the interim reporting requirements of Form 10-Q, Rule 10-01 of Regulation S-X and accounting principles generally accepted in the United States ("GAAP"). Certain financial information and disclosures normally included in our financial statements prepared annually in accordance with GAAP have been condensed or omitted. Readers of these financial statements should, therefore, refer to the consolidated financial statements and notes in our annual report on Form 10-K for the year ended December 31, 2019 (our "2019 10-K"). We have included all adjustments, in the opinion of management, consisting only of normal recurring adjustments, necessary for a fair presentation.
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 September 30, 2020 and for the three and nine months ended September 30, 2020. We present the notes to our condensed 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 development and 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 into material suitable for further processing into commercial nuclear reactor fuel.
•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 and the commercial nuclear industry. Services provided to the U.S. Government include 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 are conducted through joint ventures. This segment also develops technology for a variety of applications, including advanced nuclear power sources, and offers complete advanced nuclear fuel and reactor design and engineering, licensing and manufacturing services for new advanced nuclear reactors.
See Note 9 for financial information about our segments. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. For further information, refer to the consolidated financial statements and notes included in our 2019 10-K.
Divestiture of U.S.-Based Commercial Nuclear Services Business
On May 29, 2020, our subsidiary BWXT Nuclear Energy, Inc. divested its U.S.-based commercial nuclear services business, a component of our Nuclear Services Group segment. In a cashless transaction, we exchanged net assets totaling $18.0 million, consisting primarily of property, plant and equipment and certain warranty obligations, for a manufacturing facility and the associated land of approximately the same value. The acquired assets are reported as part of the Nuclear Services Group segment.
Recently Adopted Accounting Standards
On January 1, 2020, we adopted the update to the Financial Accounting Standards Board ("FASB") Topic Financial Instruments – Credit Losses. This update requires entities to recognize expected credit losses immediately in the financial statements. We considered our customer base, credit loss history and expected loss rate in our evaluation of expected credit losses. The adoption of the provisions in this update did not have an impact on our financial position, results of operations or cash flows.
On January 1, 2020, we adopted the update to the FASB Topic Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This update simplifies the accounting for goodwill impairment by eliminating the second step from the goodwill impairment test. Goodwill impairment will now be determined by comparing the fair value of a reporting unit with its carrying amount. The adoption of the provisions in this update did not have an impact on our financial position, results of operations or cash flows.
In December 2019, the FASB issued an update to the FASB Topic Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This update simplifies various aspects related to the accounting for income taxes by eliminating certain exceptions to the general principles in Topic 740, simplifies when companies recognize deferred taxes in an interim period and clarifies certain aspects of the current guidance to promote consistent application. We elected to early adopt this update effective January 1, 2020, which did not have a material impact on our financial position, results of operations or cash flows.
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.
Provision for Income Taxes
We are subject to federal income tax in the U.S. and Canada as well as income tax within multiple U.S. state jurisdictions. We provide for income taxes based on the enacted tax laws and rates in the jurisdictions in which we conduct our operations. These jurisdictions may have regimes of taxation that vary with respect to nominal rates and with respect to the basis on which these rates are applied. This variation, along with the changes in our mix of income within these jurisdictions, can contribute to shifts in our effective tax rate from period to period.

Table of Contents
Our effective tax rate for the three months ended September 30, 2020 was 20.3% as compared to 20.6% for the three months ended September 30, 2019. Our effective tax rate for the nine months ended September 30, 2020 was 22.3% as compared to 22.1% for the nine months ended September 30, 2019. The effective tax rate for the three months ended September 30, 2020 was lower than the U.S. corporate income tax rate of 21% primarily due to the Company electing or planning to elect the global intangible low-taxed income ("GILTI") high-tax exception for the current year and retroactively to the 2018 and 2019 tax years as allowed per the final regulations released in July 2020. The effective tax rates for the nine months ended September 30, 2020 and 2019 were higher than the U.S. corporate income tax rate of 21% primarily due to state income taxes within the U.S. and the unfavorable rate differential associated with our Canadian earnings. Our effective tax rates for the nine months ended September 30, 2020 and 2019 were favorably impacted by benefits recognized for excess tax benefits related to employee share-based payments of $0.9 million and $2.0 million, respectively.
As of September 30, 2020, we had gross unrecognized tax benefits of $4.5 million (exclusive of interest and federal and state benefits), all of which would reduce our effective tax rate if recognized.
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 three and nine months ended September 30, 2020, we have recognized $16.6 million of subsidies under CEWS as an offset to operating expenses. These amounts have been included as a component of Accounts receivable – other on our condensed consolidated balance sheet as of September 30, 2020.
Cash and Cash Equivalents and Restricted Cash and Cash Equivalents
At September 30, 2020, we had restricted cash and cash equivalents totaling $6.0 million, $2.9 million of which was held for future decommissioning of facilities (which is included in Other Assets on our condensed consolidated balance sheets) and $3.1 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 condensed consolidated balance sheets to the totals presented on our condensed consolidated statement of cash flows:

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 condensed consolidated balance sheets. Based on the hedge designation at the 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 condensed consolidated statements of income.
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 September 30, 2020, we had deferred approximately $0.1 million of net gains on these derivative financial instruments. Assuming market conditions continue, we expect to recognize the majority of this amount in the next 12 months. For the three months ended September 30, 2020 and 2019, we recognized (gains) losses of $0.7 million and $0.2 million, respectively, and for the nine months ended September 30, 2020 and 2019, we recognized (gains) losses of $(0.9) million and $(1.3) million, respectively, in Other – net on our condensed consolidated statements of income associated with FX forward contracts not designated as hedges.
At September 30, 2020, our derivative financial instruments consisted of FX forward contracts with a total notional value of $239.7 million with maturities extending to July 2022. 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.

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 three months ended September 30, 2020 and 2019, we recognized net favorable changes in estimates that resulted in increases in revenues of $7.8 million and $26.5 million, respectively. During the nine months ended September 30, 2020 and 2019, we recognized net favorable changes in estimates that resulted in increases in revenues of $28.8 million and $47.9 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 recognized over time. Amounts that are withheld on our fixed-price incentive fee contracts are classified within Retainages. Certain of these amounts require conditions other than the passage of time to be achieved, with the remaining amounts only requiring the passage of time. Most long-term contracts contain provisions for progress payments. Our unbilled receivables do not contain an allowance for credit losses as we expect to invoice customers and collect all amounts for unbilled revenues. Changes in Contracts in progress and Advance billings on contracts are primarily driven by differences in the timing of revenue recognition and billings to our customers. During the nine months ended September 30, 2020, our unbilled receivables increased $52.8 million primarily as a result of the timing of milestone billings on certain firm-fixed-price contracts within our Nuclear Power Group segment, partially offset by decreases in unbilled receivables within our Nuclear Operations Group segment. During the nine months ended September 30, 2020, our Advance billings on contracts decreased $8.4 million primarily as a result of revenue recognized in excess of billings. 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 received 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.

Long-Term Debt |  | $ | 902,197 |  |  | $ | 809,442 |

Maturities of long-term debt subsequent to September 30, 2020 were as follows: 2020 through 2024 – $0.0 million; 2025 – $115.0 million; and thereafter – $800.0 million.
On June 12, 2020, we issued $400 million aggregate principal amount of our 4.125% senior notes due 2028 (the "Senior Notes due 2028") pursuant to an indenture dated June 12, 2020 (the "2020 Indenture") among the Company, the guarantors party thereto and U.S. Bank National Association, as trustee. The proceeds from the issuance of the Senior Notes due 2028 were used to (1) repay in full the Term Loans, as defined below, under our Credit Agreement dated May 24, 2018 (as amended, the "Credit Facility"), (2) repay a portion of the borrowings under the Revolving Credit Facility, as defined below, under the Credit Facility, and (3) pay all fees and expenses related to the issuance of the Senior Notes due 2028.
Credit Facility
On March 24, 2020, we entered into an Amendment No. 1 to Credit Agreement (the "Amendment"), which amended the Credit Facility with Wells Fargo Bank, N.A., as administrative agent, and the other lenders party thereto. The Credit Facility originally provided for a $500 million senior secured revolving credit facility (the "Revolving Credit Facility"), a $50 million U.S. dollar senior secured term loan A made available to the Company (the "USD Term Loan") and a $250 million (U.S. dollar equivalent) Canadian dollar senior secured term loan A made available to BWXT Canada Ltd. (the "CAD Term Loan" and together with the USD Term Loan, the "Term Loans"). On June 12, 2020, we repaid in full the Term Loans, at par, with a portion of the proceeds from the issuance of the Senior Notes due 2028.
The Amendment, among other things, (1) provided additional commitments to increase the Revolving Credit Facility by $250 million, such that the Revolving Credit Facility is now $750 million; (2) extended the maturity date of the Revolving Credit Facility to March 24, 2025; (3) removed BWXT Canada Ltd. as a borrower under the Revolving Credit Facility; (4) modified the applicable margin for borrowings under the Revolving Credit Facility to be, at the Company's option, either (i) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (ii) the base rate plus a margin ranging from 0.0% to 0.75% per year, in each case depending on the Company's leverage ratio; (5) modified the commitment fee on the unused portion of the Revolving Credit Facility to range from 0.15% to 0.225% per year, depending on the Company's leverage ratio; and (6) modified the letter of credit fee with respect to each financial letter of credit and performance letter of credit issued under the Revolving Credit Facility to range from 1.0% to 1.75% and 0.75% to 1.05% per year, respectively, in each case, depending on the Company's leverage ratio.
All obligations under the Revolving Credit Facility are scheduled to mature on March 24, 2025. The proceeds of loans under the Revolving Credit Facility are available for working capital needs, permitted acquisitions and other general corporate purposes.
The Credit Facility allows for additional parties to become lenders and, subject to certain conditions, for the increase of the commitments under the Credit Facility, subject to an aggregate maximum for all additional commitments of (1) the greater of (a) $250 million and (b) 65% of EBITDA, as defined in the Credit Facility, for the last four full fiscal quarters, plus (2) all voluntary prepayments of the Term Loans, plus (3) additional amounts provided the Company is in compliance with a pro forma first lien leverage ratio test of less than or equal to 2.50 to 1.00.
The Company's obligations under the Credit Facility are guaranteed, subject to certain exceptions, by substantially all of the Company's present and future wholly owned domestic restricted subsidiaries. The Credit Facility is secured by first-priority

liens on certain assets owned by the Company and its subsidiary guarantors (other than its subsidiaries comprising its Nuclear Operations Group segment and a portion of its Nuclear Services Group segment).
The Revolving Credit Facility requires interest payments on revolving loans on a periodic basis until maturity. We may prepay all loans under the Credit Facility at any time without premium or penalty (other than customary Eurocurrency breakage costs), subject to notice requirements.
The Credit Facility includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted leverage ratio is 4.00 to 1.00, which may be increased to 4.50 to 1.00 for up to four consecutive fiscal quarters after a material acquisition. The minimum consolidated interest coverage ratio is 3.00 to 1.00. In addition, the Credit Facility contains various restrictive covenants, including with respect to debt, liens, investments, mergers, acquisitions, dividends, equity repurchases and asset sales. As of September 30, 2020, we were in compliance with all covenants set forth in the Credit Facility.
Outstanding loans under the Revolving Credit Facility bear interest at our option at either (1) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (2) the base rate plus a margin ranging from 0.0% to 0.75% per year. We are charged a commitment fee on the unused portion of the Revolving Credit Facility, and that fee ranges from 0.15% to 0.225% per year. Additionally, we are charged a letter of credit fee of between 1.0% and 1.75% per year with respect to the amount of each financial letter of credit issued under the Credit Facility, and a letter of credit fee of between 0.75% and 1.05% per year with respect to the amount of each performance letter of credit issued under the Credit Facility. The applicable margin for loans, the commitment fee and the letter of credit fees set forth above will vary quarterly based on our leverage ratio. Based on the leverage ratio applicable at September 30, 2020, the margin for Eurocurrency rate and base rate revolving loans was 1.25% and 0.25%, respectively, the letter of credit fee for financial letters of credit and performance letters of credit was 1.25% and 0.825%, respectively, and the commitment fee for the unused portion of the Revolving Credit Facility was 0.175%.
As of September 30, 2020, borrowings and letters of credit issued under the Revolving Credit Facility totaled $115.0 million and $66.1 million, respectively. As a result, as of September 30, 2020 we had $568.9 million available under the Revolving Credit Facility for borrowings and to meet letter of credit requirements. As of September 30, 2020, the interest rate on outstanding borrowings under our Credit Facility was 1.40%.
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 2028
We issued $400 million aggregate principal amount of our Senior Notes due 2028 pursuant to the 2020 Indenture. The Senior Notes due 2028 are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Credit Facility.
Interest on the Senior Notes due 2028 is payable semi-annually in cash in arrears on June 30 and December 30 of each year, commencing on December 30, 2020, at a rate of 4.125% per annum. The Senior Notes due 2028 will mature on June 30, 2028.
We may redeem the Senior Notes due 2028, in whole or in part, at any time on or after June 30, 2023 at a redemption price equal to (i) 102.063% of the principal amount to be redeemed if the redemption occurs during the twelve-month period beginning on June 30, 2023, (ii) 101.031% of the principal amount to be redeemed if the redemption occurs during the twelve-month period beginning on June 30, 2024 and (iii) 100.0% of the principal amount to be redeemed if the redemption occurs on or after June 30, 2025, in each case plus accrued and unpaid interest, if any, to, but excluding, the redemption date. At any time prior to June 30, 2023, we may also redeem up to 40.0% of the Senior Notes due 2028 with net cash proceeds of certain equity offerings at a redemption price equal to 104.125% of the principal amount of the Senior Notes due 2028 to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, at any time prior to June 30, 2023, we may redeem the Senior Notes due 2028, in whole or in part, at a redemption price equal to 100.0% of the principal amount of

the Senior Notes due 2028 to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date plus an applicable "make-whole" premium.
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 September 30, 2020, we were in compliance with all covenants set forth in the 2020 Indenture and the Senior Notes due 2028.
NOTE 5 – PENSION PLANS AND POSTRETIREMENT BENEFITS
We record the service cost component of net periodic benefit cost within Operating income on our condensed consolidated statements of income. For the three months ended September 30, 2020 and 2019, these amounts were $2.5 million and $2.1 million, respectively. For the nine months ended September 30, 2020 and 2019, these amounts were $8.5 million and $7.3 million, respectively. All other components of net periodic benefit cost are included in Other – net within the condensed consolidated statements of income.

We estimate the fair value of investments based on quoted market prices. For investments for which there are no quoted market prices, we derive fair values from available yield curves for investments of similar quality and terms.
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 September 30, 2020 and December 31, 2019, we had FX forward contracts outstanding to purchase or sell foreign currencies, primarily Canadian dollars and Euros, with a total fair value of $(1.1) million and $(0.8) million, respectively.
Other Financial Instruments
We used the following methods and assumptions in estimating our fair value disclosures for our other financial instruments, as follows:
Cash and cash equivalents and restricted cash and cash equivalents. The carrying amounts that we have reported in the accompanying condensed 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 5.375% senior notes due 2026 (the "Senior Notes due 2026") and our Senior Notes due 2028, 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 September 30, 2020 and December 31, 2019, the fair value of our Senior Notes due 2026 was $416.3 million and $423.5 million, respectively. At September 30, 2020, the fair value of our Senior Notes due 2028 was $410.0 million. The fair value of our remaining debt instruments approximated their carrying values at September 30, 2020 and December 31, 2019.
NOTE 8 – STOCK-BASED COMPENSATION
Stock-based compensation recognized for all of our plans for the three months ended September 30, 2020 and 2019 totaled $4.7 million and $3.1 million, respectively, with associated tax benefit totaling $0.9 million and $0.5 million, respectively. Stock-based compensation recognized for all of our plans for the nine months ended September 30, 2020 and 2019 totaled $12.0 million and $10.9 million, respectively, with associated tax benefit totaling $2.1 million and $1.9 million, respectively.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS
The following information should be read in conjunction with the unaudited condensed consolidated financial statements and the notes thereto included under Item 1 of this quarterly report on Form 10-Q ("Report") and the audited consolidated financial statements and the related notes and Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our annual report on Form 10-K for the year ended December 31, 2019 (our "2019 10-K").
In this Report, unless the context otherwise indicates, "we," "us" and "our" mean BWX Technologies, Inc. ("BWXT" or the "Company") and its consolidated subsidiaries.
From time to time, our management or persons acting on our behalf make forward-looking statements to inform existing and potential security holders about our Company. Forward-looking statements include those statements that express a belief, expectation or intention, as well as those that are not statements of historical fact, within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Statements and assumptions regarding expectations and projections of specific projects, our future backlog, revenues, income and capital spending, strategic investments, acquisitions or divestitures, return of capital activities, margin improvement initiatives or impacts of the novel strain of coronavirus ("COVID-19") pandemic are examples of forward-looking statements. Forward-looking statements are generally accompanied by words such as "estimate," "project," "predict," "believe," "expect," "anticipate," "plan," "seek," "goal," "could," "intend," "may," "should" or other words that convey the uncertainty of future events or outcomes. In addition, sometimes we will specifically describe a statement as being a forward-looking statement and refer to this cautionary statement.
We have based our forward-looking statements on information currently available to us and our current expectations, estimates and projections about our industries and our Company. We caution that these statements are not guarantees of future performance and you should not rely unduly on them as they involve risks, uncertainties and assumptions that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. For example, the extent to which the COVID-19 outbreak impacts our business will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the length and severity of the COVID-19 health crisis, and the actions to contain its impact, in addition to the potential recurrence or subsequent waves of COVID-19 or similar diseases. While our management considers these statements and assumptions to be reasonable, they are inherently subject to numerous factors, including potentially the risk factors described in the sections labeled Item 1A, "Risk Factors" of our 2019 10-K, of our quarterly reports on Form 10-Q for the quarters ended March 31, 2020 (our "First Quarter 2020 10-Q") and June 30, 2020 (our "Second Quarter 2020 10-Q") and of this Report, most of which are difficult to predict and many of which are beyond our control. Accordingly, our actual results may differ materially from the future performance that we have expressed or forecast in our forward-looking statements.
We have discussed many of these factors in more detail elsewhere in this Report, including under the heading "COVID-19 Assessment" of this Item 2 "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Item 1A, "Risk Factors", and in Item 1A "Risk Factors" in our 2019 10-K, our First Quarter 2020 10-Q and our Second Quarter 10-Q. These factors are not necessarily all the factors that could affect us. Unpredictable or unanticipated factors we have not discussed in this Report or in our 2019 10-K, our First Quarter 2020 10-Q and our Second Quarter 10-Q could also have material adverse effects on actual results of matters that are the subject of our forward-looking statements. We do not intend to update or review any forward-looking statement or our description of important factors, whether as a result of new information, future events or otherwise, except as required by applicable laws.
GENERAL
We operate in three reportable segments: Nuclear Operations Group, Nuclear Power Group and Nuclear Services Group. In general, we operate in capital-intensive industries and rely on large contracts for a substantial amount of our revenues. We are currently exploring growth strategies across our segments to expand and complement our existing businesses. We would expect to fund these opportunities with cash generated from operations or by raising additional capital through debt, equity or some combination thereof.
Nuclear Operations Group
The revenues of our Nuclear Operations Group segment are largely a function of defense spending by the U.S. Government. Through this segment, we engineer, design and manufacture precision naval nuclear components, reactors and
22

Table of Contents
nuclear fuel for the DOE/NNSA's Naval Nuclear Propulsion Program. In addition, we perform development and fabrication activities for missile launch tubes for U.S. Navy submarines. As a supplier of major nuclear components for certain U.S. Government programs, this segment is a significant participant in the defense industry.
Nuclear Power Group
Through this segment, we design and manufacture commercial nuclear steam generators, heat exchangers, pressure vessels, reactor components, as well as other auxiliary equipment, including containers for the storage of spent nuclear fuel and other high-level nuclear waste. This segment is a leading supplier of nuclear fuel, fuel handling systems, tooling delivery systems, nuclear-grade materials and precisely machined components, and related services for CANDU nuclear power plants. This segment also provides a variety of engineering and in-plant services and is a significant supplier to nuclear power utilities undergoing major refurbishment and plant life extension projects. Additionally, this segment is a leading global manufacturer and supplier of critical medical radioisotopes and radiopharmaceuticals.
Our Nuclear Power Group segment's overall activity primarily depends on the demand and competitiveness of nuclear energy. A significant portion of our Nuclear Power Group segment's operations depend on the timing of maintenance outages, the cyclical nature of capital expenditures and major refurbishment and life extension projects, as well as the demand for nuclear fuel and fuel handling equipment primarily in the Canadian market, which could cause variability in our financial results.
Nuclear Services Group
Our Nuclear Services Group segment provides various services to the U.S. Government. The revenues and equity in income of investees under our U.S. Government contracts are largely a function of spending of the U.S. Government and the performance scores we and our consortium partners earn in managing and operating high-consequence operations at U.S. nuclear weapons sites, national laboratories and manufacturing complexes. With its specialized capabilities of full life-cycle management of special materials, facilities and technologies, we believe our Nuclear Services Group segment is well-positioned to continue to participate in the continuing cleanup, operation and management of critical government-owned nuclear sites, laboratories and manufacturing complexes maintained by the DOE, NASA and other federal agencies. 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.
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.
Acquisition of Laker Energy Products Ltd.
On January 2, 2020, our subsidiary BWXT Canada Ltd. acquired Laker Energy Products Ltd. ("Laker Energy Products"). Laker Energy Products is a global supplier of nuclear-grade materials and precisely machined components for CANDU nuclear power utilities and employs approximately 140 personnel. Laker Energy Products is reported as part of our Nuclear Power Group segment.
Critical Accounting Policies and Estimates
For a summary of the critical accounting policies and estimates that we use in the preparation of our unaudited condensed consolidated financial statements, see Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2019 10-K. There have been no material changes to our critical accounting policies during the nine months ended September 30, 2020 with the exception of the adoption of Financial Accounting Standards Board ("FASB") Topic Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment as described in the notes to the condensed consolidated financial statements in Part I of this Report.

Accounting for Contracts
On certain of our performance obligations, we recognize revenue over time. In accordance with FASB Topic Revenue from Contracts with Customers, we are required to estimate the total amount of costs on these performance obligations. As of September 30, 2020, we have provided for the 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 revenues and costs. A principal risk on fixed-price contracts is that revenue from the customer is insufficient to 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. In some instances, we guarantee completion dates related to our projects or provide performance guarantees. Increases in costs on our fixed-price contracts could have a material adverse impact on our consolidated results of operations, financial condition and cash flows. Alternatively, reductions in overall contract costs at completion could materially improve our consolidated results of operations, financial condition and cash flows. During the three months ended September 30, 2020 and 2019, we recognized net changes in estimates related to contracts that recognize revenue over time, which increased operating income by approximately $7.8 million and $24.9 million, respectively. During the nine months ended September 30, 2020 and 2019, we recognized net changes in estimates related to contracts that recognize revenue over time, which increased operating income by approximately $28.8 million and $48.6 million, respectively.
COVID-19 Assessment
General
A global outbreak of COVID-19 has occurred impacting over 200 countries, including the U.S. and Canada where we maintain our principal operations. Developments have been occurring rapidly with respect to the spread of COVID-19 and its impact on human health and businesses, with new and changing government actions occurring on a daily basis. As a result, we have been closely monitoring the COVID-19 pandemic and its impacts and potential impacts on our business.
We have received notifications from the U.S. and Canadian governments designating BWXT as an essential business given our roles in national security, energy production and medical manufacturing. We continue to operate our facilities and have taken numerous precautions to mitigate exposure and protect the health and well-being of our workforce.
To date, we have experienced localized operational challenges as a result of employee illness, quarantines and social distancing protocols. Within our Canadian operations, revenues in our medical radioisotopes and radiopharmaceuticals business have declined year over year due to a decrease in demand for elective diagnostic procedures, and certain services scheduled during nuclear power plant outages have been rescheduled, delaying the performance of services by our Nuclear Power Group segment. We have also experienced delays in the bidding and contracting process for our U.S. Government businesses due to COVID-19 concerns.
Because developments related to the spread of COVID-19 and its impacts have been occurring rapidly, it is difficult to predict any future impact at this time. We may experience further disruptions to demand for our products and services and our operations in the future as a result of, among other things, national, state, provincial or local government enforced quarantines, worker illness or absenteeism, and travel and other restrictions. For similar reasons, the COVID-19 pandemic may also adversely impact our supply chain and other manufacturers which could delay our receipt of essential goods and services. Any number of these potential risks could have a material adverse effect on our financial condition, results of operations and cash flows. The extent to which the COVID-19 outbreak impacts our business will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact.
Government Assistance
On March 27, 2020, the U.S. Government enacted the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"), which among other things, provides employers an option to defer payroll tax payments for a limited period. Based on our evaluation of the CARES Act, we qualify for the deferral of payroll tax payments in the future and as of September 30, 2020, and we have deferred $14.4 million of payroll taxes that will be paid beginning in December 2021. Additionally, 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 three and nine months ended September 30, 2020, we have recognized $16.6 million of subsidies under CEWS as an offset to operating expenses. The Canadian Government has extended CEWS to June 2021 with a number of modifications. These modifications are expected to significantly decrease the amount of future claims for which we may qualify.

Consolidated Results of Operations
Three months ended September 30, 2020 vs. 2019
Consolidated revenues increased 2.7%, or $13.9 million, to $519.9 million in the three months ended September 30, 2020 compared to $506.0 million for the corresponding period in 2019, due to increases in revenues from our Nuclear Power Group and Nuclear Services Group segments totaling $23.7 million and $0.5 million, respectively. These increases were partially offset by a decrease in revenues in our Nuclear Operations Group segment of $8.0 million.
Consolidated operating income decreased $9.7 million to $88.8 million in the three months ended September 30, 2020 compared to $98.5 million for the corresponding period of 2019. Operating income in our Nuclear Operations Group segment decreased $25.2 million and Unallocated Corporate expenses increased $8.0 million when compared to the corresponding period of 2019. These decreases in operating income were partially offset by increases in the operating income of our Nuclear Power Group, Nuclear Services Group and Other segments of $20.2 million, $2.0 million, and $1.2 million, respectively.
Nine months ended September 30, 2020 vs. 2019
Consolidated revenues increased 12.4%, or $172.9 million, to $1,566.6 million in the nine months ended September 30, 2020 compared to $1,393.7 million for the corresponding period in 2019, due to increases in revenues from our Nuclear Operations Group, Nuclear Power Group and Nuclear Services Group segments totaling $162.9 million, $8.6 million and $11.6 million, respectively.
Consolidated operating income increased $26.8 million to $269.5 million in the nine months ended September 30, 2020 compared to $242.6 million for the corresponding period of 2019. Operating income in our Nuclear Operations Group, Nuclear Power Group, Nuclear Services Group and Other segments increased by $18.3 million, $2.3 million, $9.5 million and $3.1 million, respectively. These increases were partially offset by higher Unallocated Corporate expenses of $6.4 million when compared to the corresponding period of 2019.

Three months ended September 30, 2020 vs. 2019
Revenues decreased 2.0%, or $8.0 million, to $386.5 million in the three months ended September 30, 2020 compared to $394.5 million for the corresponding period of 2019. The decrease is related to a higher volume of certain long-lead materials in the prior year when compared to the corresponding period of 2020. This decrease was partially offset by additional volume in our naval nuclear fuel and downblending operations.
Operating income decreased $25.2 million to $68.5 million in the three months ended September 30, 2020 compared to $93.7 million for the corresponding period of 2019. The decrease was due to the operating income impact of the changes in revenues noted above in addition to higher levels of favorable contract adjustments in the prior year.
Nine months ended September 30, 2020 vs. 2019
Revenues increased 15.4%, or $162.9 million, to $1,220.5 million in the nine months ended September 30, 2020 compared to $1,057.6 million for the corresponding period of 2019 as we continue to expand production related to the Columbia-Class nuclear propulsion system. The increase comprised additional volume in the manufacture of nuclear components for U.S. Government programs and the timing of the procurement of certain long-lead materials when compared to the corresponding period of 2019. We also experienced a volume increase in our naval nuclear fuel and downblending operations.
Operating income increased $18.3 million to $244.8 million in the nine months ended September 30, 2020 compared to $226.5 million for the corresponding period of 2019. The increase was due to the operating income impact of the changes in revenues noted above.

Three months ended September 30, 2020 vs. 2019
Revenues increased 28.1%, or $23.7 million, to $108.1 million in the three months ended September 30, 2020 compared to $84.4 million for the corresponding period of 2019. This was primarily related to an increase in revenues of $11.7 million associated with the acquisition of Laker Energy Products. We also experienced higher levels of in-plant inspection, maintenance and modification services totaling $10.6 million as well as additional volume related to the fabrication of nuclear fuel and nuclear fuel handling capabilities. These increases were partially offset by lower revenues in our nuclear components business largely attributable to decreased activity associated with major steam generator design and supply contracts of $9.6 million. In addition, we experienced lower demand for our medical radioisotopes when compared to the same period in the prior year, due to a decrease in elective diagnostic procedures caused in part by the COVID-19 pandemic.
Operating income increased $20.2 million to $29.2 million in the three months ended September 30, 2020 compared to $9.0 million for the corresponding period of 2019, primarily attributable to $16.6 million of wage subsidies received under the CEWS to offset the effects of COVID-19 on our Canadian operations in addition to the operating income impact of the changes in revenues noted above.

Effective Tax Rate |  | 20.3% |  | 20.6% |  |  |  | 22.3% |  | 22.1% |  |

We primarily operate in the U.S. and Canada, and we recognize our U.S. income tax provision based on the U.S. federal statutory rate of 21% and our Canadian tax provision based on the Canadian local statutory rate of approximately 25%.
Our effective tax rate for the three months ended September 30, 2020 was 20.3% as compared to 20.6% for the three months ended September 30, 2019. Our effective tax rate for the nine months ended September 30, 2020 was 22.3% as compared to 22.1% for the nine months ended September 30, 2019. The effective tax rate for the three months ended September 30, 2020 was lower than the U.S. corporate income tax rate of 21% primarily due to the Company electing or planning to elect the global intangible low-taxed income ("GILTI") high-tax exception for the current year and retroactively to the 2018 and 2019 tax years as allowed per the final regulations released in July 2020. The effective tax rates for the nine months ended September 30, 2020 and 2019 were higher than the U.S. corporate income tax rate of 21% primarily due to state income taxes within the U.S and the unfavorable rate differential associated with our Canadian earnings. Our effective tax rates for the nine months ended September 30, 2020 and 2019 were favorably impacted by benefits recognized for excess tax benefits related to employee share-based payments of $0.9 million and $2.0 million, respectively.
Backlog
Backlog represents the dollar amount of revenue we expect to recognize in the future from contracts awarded and in progress. Not all of our expected revenue from a contract award is recorded in backlog for a variety of reasons, including that some projects are awarded and completed within the same reporting period.
Our backlog is equal to our remaining performance obligations under contracts that meet the criteria in FASB Topic Revenue from Contracts with Customers, as discussed in Note 3 to our condensed consolidated financial statements included in this Report. It is possible that our methodology for determining backlog may not be comparable to methods used by other companies.
We are subject to the budgetary and appropriations cycle of the U.S. Government as it relates to our Nuclear Operations Group and Nuclear Services Group segments. Backlog may not be indicative of future operating results, and projects in our backlog may be cancelled, modified or otherwise altered by customers.

At September 30, 2020, our Nuclear Operations Group segment's backlog with the U.S. Government was $3,182.1 million, $394.2 million of which had not yet been funded.
At September 30, 2020, our Nuclear Power Group segment had no backlog with the U.S. Government.
At September 30, 2020, our Nuclear Services Group segment's backlog with the U.S. Government was $23.1 million, all of which was funded.
Major new awards from the U.S. Government are typically received following Congressional approval of the budget for the U.S. Government's next fiscal year, which starts October 1, and may not be awarded to us before the end of the calendar year. Due to the fact that most contracts awarded by the U.S. Government are subject to these annual funding approvals, the total values of the underlying programs are significantly larger. In 2019, we received awards from the U.S. Government with a combined value in excess of $3.9 billion, inclusive of unexercised options, approximately $2.9 billion of which had been added to backlog as of September 30, 2020. The value of unexercised options excluded from backlog as of September 30, 2020 was approximately $1.0 billion, which is expected to be exercised through 2025, subject to annual Congressional appropriations.
Liquidity and Capital Resources
On June 12, 2020, we issued $400 million aggregate principal amount of our 4.125% senior notes due 2028 (the "Senior Notes due 2028") pursuant to an indenture dated June 12, 2020 (the "2020 Indenture") among the Company, the guarantors party thereto and U.S. Bank National Association, as trustee. The proceeds from the issuance of the Senior Notes due 2028 were used to (1) repay in full the Term Loans, as defined below, under our Credit Agreement dated May 24, 2018 (as amended, the "Credit Facility"), (2) repay a portion of the borrowings under the Revolving Credit Facility, as defined below, under the Credit Facility, and (3) pay all fees and expenses related to the issuance of the Senior Notes due 2028.
Credit Facility
On March 24, 2020, we entered into an Amendment No. 1 to Credit Agreement (the "Amendment"), which amended the Credit Facility with Wells Fargo Bank, N.A., as administrative agent, and the other lenders party thereto. The Credit Facility originally provided for a $500 million senior secured revolving credit facility (the "Revolving Credit Facility"), a $50 million U.S. dollar senior secured term loan A made available to the Company (the "USD Term Loan") and a $250 million (U.S. dollar equivalent) Canadian dollar senior secured term loan A made available to BWXT Canada Ltd. (the "CAD Term Loan" and together with the USD Term Loan, the "Term Loans"). On June 12, 2020, we repaid in full the Term Loans, at par, with a portion of the proceeds from the issuance of the Senior Notes due 2028.
The Amendment, among other things, (1) provided additional commitments to increase the Revolving Credit Facility by $250 million, such that the Revolving Credit Facility is now $750 million; (2) extended the maturity date of the Revolving Credit Facility to March 24, 2025; (3) removed BWXT Canada Ltd. as a borrower under the Revolving Credit Facility; (4) modified the applicable margin for borrowings under the Revolving Credit Facility to be, at the Company's option, either (i) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (ii) the base rate plus a margin ranging from 0.0% to 0.75% per year, in each case depending on the Company's leverage ratio; (5) modified the commitment fee on the unused portion of the Revolving Credit Facility to range from 0.15% to 0.225% per year, depending on the Company's leverage ratio; and (6) modified the letter of credit fee with respect to each financial letter of credit and performance letter of credit issued under the Revolving Credit Facility to range from 1.0% to 1.75% and 0.75% to 1.05% per year, respectively, in each case, depending on the Company's leverage ratio.

All obligations under the Revolving Credit Facility are scheduled to mature on March 24, 2025. The proceeds of loans under the Revolving Credit Facility are available for working capital needs, permitted acquisitions and other general corporate purposes.
The Credit Facility allows for additional parties to become lenders and, subject to certain conditions, for the increase of the commitments under the Credit Facility, subject to an aggregate maximum for all additional commitments of (1) the greater of (a) $250 million and (b) 65% of EBITDA, as defined in the Credit Facility, for the last four full fiscal quarters, plus (2) all voluntary prepayments of the Term Loans, plus (3) additional amounts provided the Company is in compliance with a pro forma first lien leverage ratio test of less than or equal to 2.50 to 1.00.
The Company's obligations under the Credit Facility are guaranteed, subject to certain exceptions, by substantially all of the Company's present and future wholly owned domestic restricted subsidiaries. The Credit Facility is secured by first-priority liens on certain assets owned by the Company and its subsidiary guarantors (other than its subsidiaries comprising its Nuclear Operations Group segment and a portion of its Nuclear Services Group segment).
The Revolving Credit Facility requires interest payments on revolving loans on a periodic basis until maturity. We may prepay all loans under the Credit Facility at any time without premium or penalty (other than customary Eurocurrency breakage costs), subject to notice requirements.
The Credit Facility includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted leverage ratio is 4.00 to 1.00, which may be increased to 4.50 to 1.00 for up to four consecutive fiscal quarters after a material acquisition. The minimum consolidated interest coverage ratio is 3.00 to 1.00. In addition, the Credit Facility contains various restrictive covenants, including with respect to debt, liens, investments, mergers, acquisitions, dividends, equity repurchases and asset sales. As of September 30, 2020, we were in compliance with all covenants set forth in the Credit Facility.
Outstanding loans under the Revolving Credit Facility bear interest at our option at either (1) the Eurocurrency rate plus a margin ranging from 1.0% to 1.75% per year or (2) the base rate plus a margin ranging from 0.0% to 0.75% per year. We are charged a commitment fee on the unused portion of the Revolving Credit Facility, and that fee ranges from 0.15% to 0.225% per year. Additionally, we are charged a letter of credit fee of between 1.0% and 1.75% per year with respect to the amount of each financial letter of credit issued under the Credit Facility, and a letter of credit fee of between 0.75% and 1.05% per year with respect to the amount of each performance letter of credit issued under the Credit Facility. The applicable margin for loans, the commitment fee and the letter of credit fees set forth above will vary quarterly based on our leverage ratio. Based on the leverage ratio applicable at September 30, 2020, the margin for Eurocurrency rate and base rate revolving loans was 1.25% and 0.25%, respectively, the letter of credit fee for financial letters of credit and performance letters of credit was 1.25% and 0.825%, respectively, and the commitment fee for the unused portion of the Revolving Credit Facility was 0.175%.
As of September 30, 2020, borrowings and letters of credit issued under the Revolving Credit Facility totaled $115.0 million and $66.1 million, respectively. As a result, as of September 30, 2020 we had $568.9 million available under the Revolving Credit Facility for borrowings and to meet letter of credit requirements. As of September 30, 2020, the interest rate on outstanding borrowings under our Credit Facility was 1.40%.
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 (the "2018 Indenture"), among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank National Association, as trustee. The Senior Notes due 2026 are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Credit Facility.

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 September 30, 2020, bonds issued and outstanding under these arrangements totaled approximately $73.4 million.

Long-term Benefit Obligations
As of September 30, 2020, we had underfunded defined benefit pension and postretirement benefit plans with obligations totaling approximately $176.0 million. These long-term liabilities are expected to require use of our resources to satisfy future funding obligations. Based largely on statutory funding requirements, we expect to make contributions of approximately $4.4 million for the remainder of 2020 related to our pension and postretirement plans. We may also make additional contributions based on a variety of factors including, but not limited to, tax planning, evaluation of funded status and risk mitigation strategies.
Other
Our domestic and foreign cash and cash equivalents, restricted cash and cash equivalents and investments as of September 30, 2020 and December 31, 2019 were as follows:

|  | September 30, 2020 |  | December 31, 2019
|  | (In thousands)
Domestic |  | $ | 43,075 |  |  | $ | 76,337 |
Foreign |  | 18,788 |  |  | 29,526 |
Total |  | $ | 61,863 |  |  | $ | 105,863 |

Our working capital increased by $102.0 million to $327.0 million at September 30, 2020 from $225.0 million at December 31, 2019, primarily attributable to changes in contracts in progress and advance billings due to the timing of project cash flows and an increase in accounts receivable.
Our net cash provided by operating activities increased by $57.1 million to $148.1 million in the nine months ended September 30, 2020, compared to $91.0 million in the nine months ended September 30, 2019. The increase in cash provided by operating activities was primarily attributable to an increase in net income and a decrease in working capital needs when compared to the corresponding period of the prior year.
Our net cash used in investing activities increased by $71.2 million to $193.6 million in the nine months ended September 30, 2020, compared to $122.4 million in the nine months ended September 30, 2019. The increase in cash used in investing activities was primarily attributable to an increase in purchases of property, plant and equipment of $57.3 million as well as our acquisition of Laker Energy Products for $15.9 million in the three months ended March 31, 2020.
Our net cash provided by financing activities decreased by $9.9 million to $5.1 million in the nine months ended September 30, 2020, compared to cash provided by financing activities of $15.0 million in the nine months ended September 30, 2019. The decrease in cash provided by financing activities was primarily attributable to the payment of debt issuance costs of $6.8 million in the nine months ended September 30, 2020 and a $5.7 million increase in dividends paid to common shareholders compared to the prior year.
At September 30, 2020, we had restricted cash and cash equivalents totaling $6.0 million, $2.9 million of which was held for future decommissioning of facilities (which is included in other assets on our condensed consolidated balance sheets) and $3.1 million of which was held to meet reinsurance reserve requirements of our captive insurer.
At September 30, 2020, we had short-term and long-term investments with a fair value of $11.2 million. Our investment portfolio consists primarily of U.S. Government and agency securities, corporate bonds 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 unrealized gains and losses, net of tax, being reported as a component of other comprehensive income. Our equity securities are carried at fair value with the unrealized gains and losses reported in earnings.
Based on our liquidity position, we believe we have sufficient cash and letter of credit and borrowing capacity to fund our operating requirements for at least the next 12 months.

Item 4. CONTROLS AND PROCEDURES
As of the end of the period covered by this Report, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) adopted by the Securities and Exchange Commission ("SEC") under the Exchange Act). This evaluation was conducted under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Our disclosure controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. You should note that the design of any system of disclosure controls and procedures is based in part upon various assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. Based on the evaluation referred to above, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures are effective as of September 30, 2020 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and such information is accumulated and communicated to management as appropriate to allow timely decisions regarding disclosure. There has been no change in our internal control over financial reporting during the three months ended September 30, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

OTHER INFORMATION
Item 1. LEGAL PROCEEDINGS
For information regarding ongoing investigations and litigation, see Note 6 to our unaudited condensed consolidated financial statements in Part I of this Report, which we incorporate by reference into this Item.
Item 1A. RISK FACTORS
In addition to the other information in this Report, the other factors presented in Item 1A "Risk Factors" in our 2019 10-K and our First and Second Quarter Form 10-Q are some of the factors that could materially affect our business, financial condition or future results. There have been no material changes to our risk factors from those disclosed in our 2019 10-K or our First or Second Quarter Form 10-Q, except as noted below:
Actual or threatened public health epidemics or outbreaks, such as the recent outbreak of the COVID-19 illness, could have a material adverse effect on our business and results of operations.
Actual or threatened public health epidemics or outbreaks, such as the recent global outbreak of the novel coronavirus disease ("COVID-19"), could have a material adverse effect on our business and results of operations. COVID-19, which has been declared by the World Health Organization to be a pandemic, has spread to over 200 countries, including every state in the United States. COVID-19 is impacting worldwide economic activity and has resulted in travel disruption, trade disruption and has affected companies’ operations around the world, including us. A public health epidemic, including COVID-19, poses the risk that we or our employees, contractors, suppliers, customers and other partners may be prevented from conducting business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities. If significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, facility closures or other restrictions in connection with the COVID-19 pandemic, our operations will likely be impacted. Although our U.S. and Canadian facilities have to date been deemed "essential" by federal, state and local authorities and currently continue to operate, there can be no assurance that such authorities will not impose restrictions on the operations of our facilities as a result of the COVID-19 pandemic or that our facilities will continue to operate during the pandemic. If our operations or the operations of our customers or our suppliers are restricted, we may be unable to perform fully on our contracts and our costs may increase as a result of the COVID-19 outbreak. These cost increases may result in unfavorable changes in estimates which may not be fully recoverable or adequately covered by insurance or through government assistance programs such as the Coronavirus Aid, Relief and Economic Security Act in the U.S. or the Canada Emergency Wage Subsidy (the "CEWS").
While it is not possible at this time to estimate the impact that COVID-19 could have on our business, the continued spread of COVID-19 and the measures taken by the governments of countries affected, as well as measures taken by state and local authorities in the United States, could disrupt the supply chain and the manufacture or shipment of our products and adversely impact our business, financial condition or results of operations. We have already experienced delays in the bidding and contracting process for our U.S. Government businesses, as well as the rescheduling of certain services that our Canadian nuclear service business provides during nuclear power plant outages. Additionally, we have noted a year over year decline in revenues in our medical radioisotopes and radiopharmaceuticals business due to a decrease in demand for elective diagnostic procedures. More widespread or further delays could have a material adverse impact on our results of operations.
The COVID-19 outbreak and mitigation measures may also have an adverse impact on global economic conditions, which could have an adverse effect on our business. The extent to which the COVID-19 outbreak impacts our business will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact.
Additionally, the Canadian Government may review and audit the wage subsidies received under the CEWS and could disallow benefits for which we have applied. If these subsidies are reduced, disallowed or repealed due to changes in law or determination by the Canadian Government, it could have a material adverse effect on our financial condition, results of operations and cash flows. Moreover, there may be public scrutiny of government aid beneficiaries and as a result, our reputation could be harmed by participating in the CEWS.
