| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies A. Organization Leonardo DRS, Inc., together with its wholly owned subsidiaries (hereinafter, “DRS,” “the Company,” “us,” “our,” or “we”) is a supplier of defense electronics products, systems and military support services. The Company’s largest shareholder is Leonardo S.p.A (hereinafter, “Leonardo S.p.A.”), an Italian multi-national aerospace, defense and security company headquartered in Rome, Italy, through its ultimate sole ownership of Leonardo US Holding, LLC (“US Holding”). US Holding is the majority stockholder of the Company. DRS is a provider of defense products and technologies that are used across land, air, sea, space and cyber domains. Our diverse array of defense systems and solutions are offered to all branches of the U.S. military, major aerospace and defense prime contractors, government intelligence agencies, international military customers and industrial markets for deployment on a wide range of military platforms. We focus our capabilities in areas of critical importance to the U.S. military, such as advanced sensing, network computing, force protection and electrical power and propulsion. These capabilities directly align with our two reportable segments: Advanced Sensing and Computing and Integrated Mission Systems. The U.S. Department of Defense (“DoD”) is our largest customer and accounts for approximately 80% and 84% of our total revenues as an end-user for the years ended December 31, 2023 and 2022, respectively. Specific international and commercial market opportunities exist within these segments and comprise approximately 20% and 16% of our total revenues for the years ended December 31, 2023 and 2022, respectively. Our two reportable segments reflect the way performance is assessed and resources are allocated by our Chief Executive Officer, who is our chief operating decision maker (“CODM”). Advanced Sensing and Computing The Advanced Sensing and Computing (“ASC”) segment designs, develops and manufactures sensing and network computing technology that enables real-time situational awareness required for enhanced operational decision making and execution by our customers. Our leading sensing capabilities span applications including missions requiring advanced detection, precision targeting and surveillance sensing, long range electro-optic/infrared (“EO/IR”), signals intelligence (“SIGINT”) and other intelligence systems, electronic warfare (“EW”), ground vehicle sensing, next generation active electronically scanned array tactical radars, dismounted soldier sensing and space sensing. Across our offerings, we are focused on advancing sensor distance, precision, clarity, definition, spectral depth and effectiveness. Furthermore, we seek to leverage our multi-decade experience to optimize size, weight, power and cost tailored to our customers’ specific mission requirements, including in space-based applications for earth surveillance and missile tracking. Our sensing capabilities are complemented by our rugged, trusted and cyber resilient network computing products. Our network computing offering is utilized across a broad range of mission applications including platform computing on ground and shipboard (both surface ship and submarine) for advanced battle management, combat systems, radar, command and control (“C2”), tactical networks, tactical computing and communications. Our network computing products support the DoD’s need for greater situational understanding at the tactical edge and permits data to be rapidly transmitted securely from command centers to forward-positioned defense assets. Integrated Mission Systems Our Integrated Mission Systems (“IMS”) segment designs, develops, manufactures and integrates power conversion, control and distribution systems, ship propulsion systems, motors and variable frequency drives, force protection systems, transportation and logistics systems for the U.S. and allied defense customers. Our naval power and propulsion systems are providing next-generation power capabilities for the future fleet. DRS is currently a leading provider of next-generation electrical propulsion systems for the U.S. Navy. We provide power conversion, control, distribution and propulsion systems for the Navy’s top priority shipbuilding programs, including the Columbia Class ballistic missile submarine, the first modern U.S. electric drive submarine. We believe DRS is well positioned to meet the needs of an increasingly electrified fleet with our high-efficiency, power dense permanent magnet motors, energy storage systems and associated efficient, rugged and compact power conversion, electrical actuation systems, and advanced cooling technologies. DRS has a long history of providing a number of other critical products to the U.S. Navy with a significant installed base on submarines, aircraft carriers and other surface ships including motor controllers, instrumentation and control equipment, electrical actuation systems, and thermal management systems for electronics and ship stores refrigeration. Our technologies and systems help protect U.S. forces and assets against increasingly sophisticated and proliferating threats. DRS is an integrator of systems in ground vehicles for short-range air defense, counter-unmanned aerial systems (“C-UAS”), and vehicle survivability and protection. This integrator role includes utilizing radars, EW equipment, reconnaissance and surveillance systems, modular combat vehicle turrets, and stabilized sensor suites, and kinetic countermeasures for short-range air defense. Our force protection systems, including solutions for C-UAS, short-range air defense systems and active protection systems used to defend ground combat vehicles help protect personnel and defense assets from these growing threats. Other The Company separately presents the unallocable costs associated with corporate functions and certain non-operating subsidiaries of the Company as Corporate & Eliminations. See Note 19 : Segment Information for further information regarding our business segments. B. Basis of presentation The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of DRS, its wholly owned subsidiaries and its controlling interests. Interests in joint ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts significant influence, the Company applies the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation. C. Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant of these estimates and assumptions relate to the recognition of contract revenues and estimated costs to complete contracts in process, recoverability of reported amounts of goodwill and intangible assets, valuation of acquired intangibles, accounting for business combinations, valuation of pensions and other postretirement benefits, the valuation of deferred tax assets and liabilities and the valuation of unrecognized tax benefits. Actual results could differ from these estimates. D. Revenue Recognition Our revenues consist of sales of products (tangible goods) and sales of services to customers. We recognize the majority of our revenue from contracts with customers using an over time, percentage of completion, cost-to-cost method of accounting measured by the ratio of cumulative costs incurred to date to estimated total contract costs at completion (the "cost-to-cost method"). On certain other contracts, primarily time-and-material (“T&M”) and cost-plus contracts, revenue is recognized using the right-to-invoice practical expedient as we are contractually able to bill our customers based on control transferred to the customer. See Note 3 : Revenue from Contracts with Customers for additional information regarding revenue recognition. E. Cost of Revenues Cost of revenues includes materials, labor and overhead costs incurred in the manufacturing, design, and provision of products and services sold in the period as well as warranty costs. Material costs include raw materials, purchased components and sub-assemblies, outside processing and inbound freight costs. Labor and overhead costs consist of direct and indirect manufacturing costs, including wages and fringe benefits, operating supplies, depreciation and amortization, occupancy costs, and purchasing, receiving and inspection costs. F. Costs to Fulfill a Contract Costs to fulfill a contract that are incremental direct costs incurred to fulfill a contract with a customer, including sales commissions and dealer fees, and are capitalized if material. Costs to fulfill a contract include costs directly related to a contract or a specific anticipated contract (for example, mobilization, set-up and certain design costs) that generate or enhance our ability to satisfy our performance obligations under these contracts. These costs are capitalized to the extent they are expected to be recovered from the associated contract. Capitalized costs to obtain or fulfill a contract are amortized to expense over the expected period of benefit for contracts with terms greater than one year on a systematic basis that is consistent with the pattern of transfer of the associated goods and services to the customer. As a practical expedient, capitalized costs to obtain or fulfill a contract with a term of one year or less are expensed as incurred. Capitalized costs to obtain or fulfill a contract were $52 million and $34 million at December 31, 2023 and 2022, respectively. G. Research and Development Expenses We conduct research and development (“R&D”) activities using our own funds (referred to as company-funded R&D or independent research and development (“IR&D”)) and under contractual arrangements with our customers (referred to as customer-funded R&D) to enhance existing products and services and to develop future technologies. R&D costs include basic research, applied research, concept formulation studies, design, development, and related test activities. IR&D costs are allocated to customer contracts as part of the general and administrative overhead costs and generally recoverable on our customer contracts with the U.S. government. Customer-funded R&D costs are charged directly to the related customer contract. R&D costs are expensed as incurred. Company-funded R&D charged to general and administrative expenses totaled $82 million, $58 million, and $48 million in 2023, 2022 and 2021, respectively. H. Foreign Currency Significant transactions in foreign currencies are translated into U.S. dollars at the approximate prevailing rate at the time of the transaction. Foreign exchange transaction gains and losses in 2023, 2022 and 2021 were immaterial to the Company's results of operations. The operations of the Company's foreign subsidiaries are translated from the local (functional) currencies into U.S. dollars using weighted average rates of exchange during each monthly period. The rates of exchange at each balance sheet date are used for translating certain balance sheet accounts and gains or losses resulting from these translation adjustments are included in the accompanying Consolidated Balance Sheets as a component of other comprehensive income. I. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, deposits with banks or other short-term, highly liquid investments with original maturities of three months or less. J. Accounts Receivable Accounts receivable consist of amounts currently due from customers. We maintain an allowance recorded in the allowance for credit losses account that is estimated and recorded utilizing relevant information about past events, including historical experience, current conditions and a reasonable and supportable forecast that affects the collectability of the related financial asset. See Note 4 : Accounts Receivable for additional information regarding accounts receivable. K. Inventories Inventories are recorded at the lower of cost (determined by either actual, weighted average or first-in, first-out methods) or net realizable value, and include direct production costs as well as indirect costs, such as factory overhead. The net realizable value is calculated as the expected sales price in the course of normal operations net of estimated costs to finish and sell the goods. See Note 6 : Inventories for additional information regarding inventories. L. Property, Plant and Equipment Property, plant and equipment is carried at cost less accumulated depreciation. Depreciation is calculated on the straight-line method. The estimated useful lives of plant, machinery and equipment and building and building improvements generally range from 3 to 10 years and 15 to 40 years, respectively. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvements or the remaining life of the lease. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the Consolidated Balance Sheets, and the net gain or loss is included in the determination of net earnings. Maintenance and repairs are charged to operations as incurred and renewals and improvements are capitalized. See Note 7 : Property, Plant and Equipment for additional information regarding property, plant and equipment. M. Goodwill Goodwill represents the excess purchase price paid to acquire a business over the fair value of net assets acquired. Goodwill is assigned to reporting units and is reviewed for impairment at the reporting unit level on an annual basis, or whenever changes in circumstances indicate that the carrying amount may not be recoverable. A reporting unit is an operating segment, or one level below that operating segment (the component level) if discrete financial information is prepared and regularly reviewed by the segment manager. Two or more components of an operating segment may be aggregated and deemed a single reporting unit if the components have similar economic characteristics. Based upon the aggregation criteria the Company concluded it had six and seven reporting units at December 31, 2023 and 2022, respectively. Historically, we assessed the recoverability of our goodwill as the last day of our fourth quarter. In 2023, we changed the date of our annual goodwill impairment assessment to the first day of our fourth quarter to better align with our strategic business planning process and allow for operational expediency. The Company believes this change does not represent a material change to a method of applying an accounting principle. This voluntary change in accounting principle, applied prospectively, is preferable as it aligns the annual goodwill impairment test date more closely with our internal budgeting process and did not delay, accelerate or avoid an impairment of our goodwill. The Company uses quantitative assessments and qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the optional qualitative assessment is performed (Step 0) and the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an additional quantitative fair value test (Step 1) is performed. When performing the Step 1 goodwill impairment test, we compare the fair values of each of our reporting units to their respective carrying values. In order to compute the fair value of our reporting units, we primarily use the income approach based on the discounted cash flows that each reporting unit expects to generate in the future, consistent with our operating plans. Determining the fair value of our reporting units requires significant judgments, including the timing and amount of future cash flows, long-term growth rates, determination of the weighted average cost of capital and terminal value assumptions. If, based on the quantitative fair value test, the Company concludes that the carrying value of the reporting unit exceeds its fair value, the Company will recognize a goodwill impairment loss in an amount equal to that excess. The Company completed impairment tests as of October 1, 2023 and December 31, 2022 and 2021 and no adjustment to the carrying value of goodwill was deemed to be necessary. See Note 9 : Goodwill for additional information regarding goodwill. N. Long-Lived Assets and Acquired Identifiable Intangible Assets Identifiable intangible assets represent assets acquired as part of the Company's business acquisitions and include customer and program/contract-related assets. The values assigned to acquired identifiable intangible assets are determined as of the date of acquisition based on estimates and judgments regarding expectations for the estimated future after-tax cash flows from those assets over their lives, including the probability of expected future contract renewals and revenues, all of which are discounted to present value. The Company assesses the recoverability of the carrying value of its long-lived assets and intangible assets with finite useful lives whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable. If there are any indicators of impairment present, the Company then evaluates the recoverability of the potentially impaired long-lived assets and acquired identifiable intangible assets based upon expectations of undiscounted net cash flows from such assets. If the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset or asset group, a loss is recognized for the difference between the estimated fair value and the carrying amount of the assets. Assets to be disposed of, including those of discontinued operations, are reported at the lower of the carrying amount or fair value, less the costs to sell. See Note 7 : Property, Plant and Equipment and Note 10 : Intangible Assets for additional information regarding long-lived assets and intangible assets. O. Pension and Other Postretirement Benefits The obligations for the Company's pension plans and postretirement benefit plans and the related annual costs of employee benefits are calculated based on several long-term assumptions, including discount rates for employee benefit liabilities, rates of return on plan assets, expected annual rates of salary increases for employee participants in the case of pension plans and expected annual increases in the costs of medical and other health care benefits in the case of postretirement benefit plans. These long-term assumptions are subject to revision based on changes in interest rates, financial market conditions, expected versus actual returns on plan assets, participant mortality rates and other actuarial assumptions, including future rates of salary increases, benefit formulas and levels, and rates of increase in the costs of benefits. Changes in these assumptions, if significant, can materially affect the amount of annual net periodic benefit costs recognized in the Company's results of operations from one year to the next, the liabilities for the pension plans and postretirement benefit plans and the Company's annual cash requirements to fund these plans. See Note 14 : Pension and Other Postretirement Benefits for further information regarding our pension and postretirement plans. P. Income Taxes Beginning October 4, 2022, DRS began filing a consolidated return with only DRS and subsidiaries for federal and state purposes. Prior to October 4, 2022, DRS was included in the U.S. federal and state tax returns of US Holding. DRS and US Holding had entered into a Tax Allocation Agreement (“Tax Allocation Agreement”), dated as of November 16, 2020, with members of an affiliated group, as defined in Section 1504(a) of the U.S. Internal Revenue Code of 1986, as amended (the “Tax Code”), members of one or more consolidated, combined, unitary or similar state tax groups and additional parties who are part of an “expanded affiliated group” for certain tax purposes. The agreement provided for the method of computing and allocating the consolidated U.S. federal tax liability of the affiliated group among its members and of allocating any state group tax liabilities among the state members for the taxable year ending December 31, 2008 and each subsequent year in which the parties are members of a group (whether federal or state). The agreement also provided for reimbursement of US Holding and/or DRS for payment of such tax liabilities, for compensation of any member for use of its “net operating loss” or “tax credits” in arriving at such tax liabilities and the allocation and payment of any refund arising from a carryback of net operating losses or tax credits from subsequent taxable years. Under the agreement, the parties agreed to calculate and allocate their respective tax liabilities and other tax attributes for taxable years beginning with the first consolidated taxable year that included DRS (i.e., the taxable year ended December 31, 2008) as if the agreement was then in effect. Although DRS will file its federal consolidated return outside of US Holding post October 3, 2022, the Tax Allocation Agreement will remain in effect for all historic unaudited periods (federal or state) and all applicable prospective periods where the expanded affiliated relationship may warrant it. The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. Income taxes as presented attribute deferred income taxes of US Holding to DRS in a manner that is systematic, rational and consistent with the asset and liability method and the governing Tax Allocation Agreement which allocates the tax liability amongst the entities, including DRS. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of DRS’ assets and liabilities and are adjusted for changes in tax rates and tax laws when such changes are enacted. In general, the taxable income of DRS is included in the consolidated U.S. federal and state tax returns of US Holding for the short taxable year ended October 3, 2022. Where applicable, US Holding’s current portion of U.S. federal income taxes payable were offset against DRS’ net operating loss carryforwards in the period the related tax expense was recorded. Consequently, our net operating loss carryforwards are deemed to have been settled with US Holding in each year in an amount commensurate with the carrying value of the tax effected net operating loss utilized. If management determines that some portion or all of a deferred tax asset is not “more likely than not” to be realized, a valuation allowance is recorded as a component of the income tax provision to reduce the deferred tax asset to the amounts expected to be realized. In determining whether the Company’s deferred tax assets are realizable, management considers all evidence, both positive and negative, including the history of financial reporting earnings, existing taxable temporary differences and their projected reversals, as well as projected future income and tax planning strategies. We believe it is more likely than not that we will generate sufficient taxable income in future periods to realize our deferred tax assets, subject to the valuation allowances recognized. The Company assesses its tax positions for all periods open to examination by tax authorities based on the latest available information. Those positions are evaluated to determine whether they will more likely than not be sustained upon examination by the relevant taxing authorities. Liabilities for unrecognized tax benefits are measured based on the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. These unrecognized tax benefits are recorded as a component of income tax expense. Interest and penalties related to unrecognized tax benefits are not material. The implementation of a modified territorial tax system by the Tax Cuts and Jobs Act of 2017 (“TCJA”) subjects us to tax on our Global Intangible Low-Taxed Income (“GILTI”) starting with fiscal 2019. The FASB has permitted companies to make an accounting policy decision to either (1) treat taxes due on future GILTI inclusions in U.S. taxable income as a current-period expense when incurred (“period cost method”) or (2) factor such amounts into the measurement of its deferred taxes. The Company has elected to use the period cost method. See Note 12 : Income Taxes for additional information regarding income taxes. Q. Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net earnings by the weighted average number of shares of common stock outstanding during each period. The computation of diluted EPS includes the dilutive effect of outstanding share-based compensation awards, only in periods in which such effect would have been dilutive for the period. In February 2021, the Company completed a forward stock split of 1,450,000-for-1 share of common stock. Additionally, on November 23, 2022, the Company completed a forward stock split of 1.451345331-for-1 share of common stock. The consolidated financial statements were retroactively adjusted as necessary to reflect the November 23, 2022 forward stock split for all periods presented. In addition, 49,742,187 shares of common stock were issued in connection with the RADA merger on November 28, 2022. There were 145 million and 210 million basic and diluted common shares outstanding before and after the November 23, 2022 forward stock split, respectively, for all periods presented. See Note 16 : Earnings Per Share for additional information regarding earnings per share. R. Fair Value Measurements Fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant on the measurement date. We are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three hierarchical levels used to measure fair value are as follows: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are directly or indirectly observable. Level 3 — Significant inputs to the valuation model are unobservable. In certain instances, fair value is determined through information obtained from third parties using the latest available market data. In obtaining such data from third parties, we have evaluated the methodologies used to develop the estimate of fair value in order to assess whether such valuations are representative of fair value. The Company categorizes plan assets for disclosure purposes in accordance with this fair value hierarchy. Certain plan investments are measured at fair value using the net asset value (“NAV”) per share (or its equivalent) practical expedient and are therefore not categorized as Level 1, 2, or 3. NAV is defined as the total value of the fund divided by the number of the fund’s shares outstanding. See Note 14: Pension and Other Postretirement Benefits for further information regarding our pension and postretirement plans. The fair value of the Company’s outstanding debt obligations is calculated using Level 2 inputs, based on interest rates available for debt with terms and maturities similar to the Company’s existing debt arrangements. See Note 13: Debt for further information regarding debt. S. Financial Instruments Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and other current liabilities. Financial instruments are reported in the Consolidated Balance Sheets at carrying value as of December 31, 2023 and 2022. T. Acquisitions, Investments, Variable Interest Entities and Divestitures Acquisitions Our consolidated financial statements include the operations of acquired businesses from the date of acquisition. We account for acquired businesses using the acquisition method of accounting, which requires that any assets acquired, and liabilities assumed be measured at their respective fair values on the acquisition date. The accounting for business combinations requires the Company to make significant judgments and estimates. Any excess of the fair value of consideration transferred over the assigned values of the net assets acquired is recognized as goodwill. On November 28, 2022, the Company announced the successful completion of the all-stock merger between Leonardo DRS and RADA Electronic Industries Ltd. (“RADA”), a leading Israel-based provider of small-form tactical radar, to become a combined public company. At the time of the transaction, RADA shareholders retained approximately 19% ownership in the combined Company with Leonardo DRS’s parent company, Leonardo S.p.A., (MIL: LDO), owning the remaining 81%. The acquisition of RADA has been accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations , with the Company as the accounting acquirer, which requires the assets acquired and liabilities assumed be recognized at their acquisition date fair value. The acquisition was completed on November 28, 2022, when each issued and outstanding ordinary share of RADA was converted and exchanged for one share of common stock of the Company. The total purchase consideration for RADA was $511 million and is comprised of Company’s shares issued in exchange for all issued and outstanding common shares of RADA, as well as the portion of replacement stock compensation awards’ fair value attributable to pre-combination services. See Note 2: Business Acquisition for additional information regarding the transaction. Investments Investments where we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in other noncurrent assets on our Consolidated Balance Sheets. Significant influence typically exists if we have a 20% to 50% ownership interest in the investee. Under this method of accounting, our share of the net earnings or losses of the investee is included in operating profit in other income, net on our Consolidated Statements of Earnings since the activities of the investee are closely aligned with the operations of the business segment holding the investment. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is therefore recorded during the current period. The Company sold its interest in its only investment accounted for under the equity method, Advanced Acoustic Concepts, LLC, on July 8, 2022. Our share of net earnings related to our equity method investments was $1 million and $2 million for the years ended December 31, 2022 and 2021, respectively, which was included in our Advanced Sensing and Computing business segment operating profit. The Company’s cost method investment consists of an investment in a private company in which we do not have the ability to exercise significant influence over its operating and financial activities. Management evaluates this investment for possible impairment quarterly. Variable Interest Entities The Company occasionally forms joint ventures and/or e |
