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 June 30, 2020 and for the three and six months ended June 30, 2020. We present the notes to our condensed consolidated financial statements on the basis of continuing operations, unless otherwise stated.

•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.

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 six months ended June 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.

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.

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.

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.

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.

Our effective tax rate for the three months ended June 30, 2020 was 23.4% as compared to 24.1% for the three months ended June 30, 2019. Our effective tax rate for the six months ended June 30, 2020 was 23.3% as compared to 23.1% for the six months ended June 30, 2019. The effective tax rates for the three and six months ended June 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 six months ended June 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 $1.8 million, respectively.

At June 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.

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 June 30, 2020, we had deferred approximately $0.3 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 June 30, 2020 and 2019, we recognized (gains) losses of $3.6 million and $0.1 million, respectively, and for the six months ended June 30, 2020 and 2019, we recognized (gains) losses of $(1.6) million and $(1.5) million, respectively, in Other – net on our condensed consolidated statements of income associated with FX forward contracts not designated as hedges.

At June 30, 2020, our derivative financial instruments consisted of FX forward contracts with a total notional value of $159.7 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.
