- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

Summary of Significant Accounting Policies	Mar. 31, 2022
Accounting Policies [Abstract]
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 is controlled by Leonardo S.p.A. (hereinafter, “Leonardo S.p.A.,” “the Parent”), an Italian multi-national aerospace, defense and security company headquartered in Rome, Italy, through its direct sole ownership of Leonardo US Holding, Inc. (“US Holding”). US Holding is the direct and sole shareholder 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, electronic warfare (“EW”) and cyber, network computing, communications, force protection and electrical power conversion 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 85% and 86% of our total revenues as an end-user for the periods ended March 31, 2022 and March 31, 2021, respectively. Specific international and commercial market opportunities exist within these segments and make up approximately 15% and 14% of our total revenues for the periods ended March 31, 2022 and March 31, 2021, 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 (“ASC”) The ASC segment provides sensing and computing systems and subsystem solutions to the U.S. military and allied nations focused on solving the most complex threat dynamics facing our service men and women today. We provide world class sensing products in all warfighting domains along with the computation systems to provide situational understanding. Our technologies and products are deployed on nearly all military platforms across land, sea, air, cyberspace, and space on individual soldiers, ground vehicles, ships, aircraft, and satellites. We have market leading capabilities in electro-optic and infrared imaging, advanced lasers, electronic warfare and cyber, communications, and computing in these domains. Integrated Mission Systems (“IMS”) The IMS segment provides critical force protection, platform integration, transportation and logistics and power conversion and propulsion systems to the U.S. military and its allies. Our force protection systems provide much needed protection for our service members and military assets from evolving and proliferating threats and include advanced solutions for counter-unmanned aerial systems, short-range air defense systems and active protection systems on ground vehicles. Additionally, we provide power conversion and propulsion systems for the U.S. Navy’s top priority shipbuilding programs, building on our legacy of providing power components and systems for nearly all naval combat vessels for three decades, positioning us to continue as a leading provider of electrical ship propulsion systems and components for the U.S. Navy and its allies. 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 15: Segment Information for further information regarding our business segments. B.Basis of presentation The accompanying unaudited 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 and contain all adjustments, which are of a normal and recurring nature, considered necessary by management to present fairly the financial position, results of operations and cash flows for the periods presented. Interests in 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. Certain prior year amounts have been reclassified to conform to current year presentation. Interim Financial Statements. The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These rules and regulations permit some of the information and footnote disclosures included in financial statements prepared in accordance with U.S. GAAP to be condensed or omitted. These unaudited Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements as of and for the year ended December 31, 2021 included in our Annual Report on Form 10-K for the year end December 31, 2021, filed with the SEC on March 28, 2022. 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, long-lived assets and intangible assets, 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 On January 1, 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, and the related amendments of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, which supersedes most previous U.S. GAAP revenue recognition guidance. As of the date of adoption, we elected the practical expedient for contract modifications, which allows us to assume that the terms of the contract that existed at the beginning of the earliest period presented have been in place since the inception of the contract on the basis that it is not practical to separately evaluate the effects of all prior contract modifications. 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 (“POC”) cost-to-cost method of accounting. 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 customer based on control transferred to the customer. See Note 2. 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.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. Substantially all customer funded R&D costs are charged to cost of revenues as incurred. G.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 the periods ended March 31, 2022 and March 31, 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 earnings. H.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. I.Accounts Receivable Accounts receivable consist of amounts billed and 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 3: Accounts Receivable for additional information regarding accounts receivable. J.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 4: Inventories for additional information regarding inventories. K.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 Sheet, 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 5: Property, Plant and Equipment for additional information regarding property, plant and equipment. L.Goodwill On January 1, 2018, we early adopted ASU 2017-04, Intangibles ‐ Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment. The standard simplifies the measurement of goodwill impairment by eliminating the requirement that an entity compute the implied fair value of goodwill based on the fair values of its assets and liabilities to measure impairment. Instead, goodwill impairment will be measured as the difference between the fair value and the carrying value of the reporting unit. 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 seven reporting units at both March 31, 2022 and December 31, 2021. The annual impairment test is conducted as of December 31. The Company did not identify any triggering event during the quarters ended March 31, 2022 or March 31, 2021. See Note 7: Goodwill for additional information regarding goodwill. M.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 5: Property, Plant and Equipment and Note 8: Intangible Assets for additional information regarding long-lived assets and intangible assets. N.Derivative Financial Instruments The Company does not use derivative financial instruments for trading purposes. All derivative instruments are carried on the Consolidated Balance Sheet as either assets or liabilities at fair value. The classification of gains and losses resulting from changes in the fair values of derivatives depends on the intended use of the derivative and its resultant designation. The Company had no significant derivative or hedging instruments for the periods presented. 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 11: Pension and Other Postretirement Benefits for further information regarding our pension and postretirement plans. P.Income Taxes We and US Holding have 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 provides 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, 2021 and each subsequent year in which the parties are members of a group (whether federal or state). The agreement also provides 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 have 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. We calculate the provision for incomes taxes during interim periods by applying an estimate of our annual effective tax rate for the full year to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items. 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. 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. See Note 9: 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 stock-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. The consolidated financial statements have been adjusted to reflect the forward stock split for all periods presented. There were 100 shares and 145 million basic and diluted common shares outstanding before and after the forward stock split, respectively, for all periods presented. 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 12: Pension and Other Postretirement Benefits for further information regarding our pension and postretirement plans. 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 Sheet at carrying value, which other than the 7.5% Term loan due November 30, 2023, approximate fair value. See Note 10: Debt for further information regarding our debt. 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. There were no significant acquisitions that were completed for any of the periods presented. 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 Sheet. 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’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 enters into arrangements with special purpose limited liability companies for the purpose of bidding and executing on specific projects. The Company analyzes each such arrangement to determine whether it represents a variable interest entity (“VIE”). If the arrangement is determined to be a VIE, the Company assesses whether it is the primary beneficiary of the VIE and if it is, consequently required to consolidate the VIE. The Company did not have any investment in VIEs for the periods presented. Divestitures / Held for Sale On March 21, 2022, the Company entered into a definitive agreement to sell its Global Enterprise Solutions (GES) business to SES Government Solutions, Inc., a wholly-owned subsidiary of SES S.A., for $450 million in cash. GES, which is part of the ASC segment, provides commercial satellite communications to the U.S. Government and delivers satellite communications and security solutions to customers worldwide. SES S.A. has guaranteed the payment of the purchase price and performance of all other obligations of SES Government Solutions, Inc. under the agreement. The transaction is subject to customary closing conditions, including approvals under the Hart-Scott-Rodino Antitrust Improvements Act (HSR) and by The Committee on Foreign Investment in the United States (CFIUS) and The Federal Communications Commission (FCC). As of March 31, 2022, the assets and liabilities related to GES are reported on the Consolidated Balance Sheet as Held for Sale. In February 2022, the Leonardo DRS Board of Directors approved the strategic initiative to divest of the Company’s interest in AAC. On April 19, 2022 we entered into a definitive sales agreement to divest our share of our current equity investment in Advanced Acoustic Concepts (AAC) to Thales Defense & Security, Inc (TDSI), the minority partner in the Joint Venture. The sale is pending regulatory approval and is being reported as Held for Sale.

Revenue from Contracts with Customers

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Revenue from Contracts with CustomersThe Company recognizes revenue for each separately identifiable performance obligation in a contract representing an obligation to transfer a distinct good or service to a customer. In most cases, goods and services provided under the Company’s contracts are accounted for as single performance obligations due to the complex and integrated nature of our products and services. These contracts generally require significant integration of a group of goods and/or services to deliver a combined output. In some contracts, the Company provides multiple distinct goods or services to a customer. In those cases, the Company accounts for the distinct contract deliverables as separate performance obligations and allocates the transaction price to each performance obligation based on its relative standalone selling price, which is generally estimated using cost plus a reasonable margin. We classify revenues as products or services on our Consolidated Statements of Earnings based on the predominant attributes of the performance obligations. While the Company provides warranties on certain contracts, we typically do not

provide for services beyond standard assurances and therefore do not consider standard warranties to be separate performance obligations. Typically we enter into three types of contracts: fixed-price contracts, cost-plus contracts and T&M contracts (cost-plus contracts and T&M contracts are aggregated below as flexibly priced contracts). The majority of our total revenues are derived from fixed-price contracts; refer to the revenue disaggregation disclosures that follow.

For fixed-price contracts, customers agree to pay a fixed amount, negotiated in advanced for a specified scope of work.

For cost-plus contracts, typically we are reimbursed for allowable or otherwise defined total costs (defined as cost of revenues plus allowable general and administrative expenses) incurred, plus a fee. The contracts may also include incentives for various performance criteria, including quality, timeliness and cost-effectiveness. In addition, costs are generally subject to review by customers and regulatory audit agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract.

T&M contracts provide for reimbursement of labor hours expended at a contractual fixed labor rate per hour, plus the actual costs of material and other direct non-labor costs. The fixed labor rates on T&M contracts include amounts for the cost of direct labor, indirect contract costs and profit.

Estimating the transaction price for an arrangement requires judgment and is based on expected results which are determined using the Company’s historical data. We estimate that the revenue that we expect to be entitled to receive from a customer to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur.

Revenue from contracts with customers is recognized when the performance obligations are satisfied through the transfer of control over the good or service to the customer, which may occur either over time or at a point in time.

Revenues for the majority of our contracts are measured as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion (the "cost-to-cost method"). We believe this is an appropriate measure of progress toward satisfaction of performance obligations as this measure most accurately depicts the progress of our work and transfer of control to our customers. Due to the long-term nature of many of our contracts, developing the estimated total cost at completion and total transaction price often requires judgment. Factors that must be considered in estimating the cost of the work to be completed include the nature and complexity of the work to be performed, subcontractor performance and the risk and impact of delayed performance.

After establishing the estimated total cost at completion, we follow a standard Estimate at Completion (“EAC”) process in which we review the progress and performance on our ongoing contracts at least quarterly. Adjustments to original estimates for a contract's revenue, estimated costs at completion and estimated profit or loss often are required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change and are also required if contract modifications occur. When adjustments in estimated total costs at completion or in estimated total transaction price are determined, the related impact on revenue and operating income are recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Any anticipated losses on these contracts are fully recognized in the period in which the losses become evident.

EAC adjustments had the following impacts to revenue for the periods presented:


	Three Months Ended March 31,
(Dollars in millions)	2022			2021
Revenue	$	(1)		$	(1)
Total % of Revenue	—		%	—		%

The impacts noted above are attributed primarily to changes in our firm-fixed-price development type programs. As changes happen in the design required to achieve contractual specifications, those changes often result in the programs’ estimate and related profitability.

Conversely, if the requirements for the recognition of contracts over time are not met, revenue is recognized at a point in time when control transfers to the customer, which is generally upon transfer of title. In such cases, the production that is in progress and costs that will be recognized at a future point in time are reported within "inventories".

Costs to obtain a contract are incremental direct costs incurred to obtain 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 specific anticipated contract (e.g., 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.

Contract Assets and Liabilities

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheet. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities.


(Dollars in millions)	March 31, 2022		December 31, 2021
Contract assets	$	823	$	743
Contract liabilities	172		174
Net contract assets	$	651	$	569

Revenue recognized in the periods ending March 31, 2022 and March 31, 2021, that was included in the contract liability balance at the beginning of each period was $74 million and $69 million, respectively.

The change in the balances of the Company’s contract assets and liabilities primarily results from timing differences between revenue recognition and customer billings and/or payments.

Contract assets related to amounts withheld by customers until contract completion are not considered a significant financing component of our contracts because the intent is to protect the customers from our failure to satisfactorily complete our performance obligations. Payments received from customers in advance of revenue recognition (contract liabilities) are not considered a significant financing component of our contracts because they are utilized to pay for contract costs within a one-year period or are requested by us to ensure the customers meet their payment obligations.

Value of Remaining Performance Obligations

The value of remaining performance obligations, which we also refer to as total backlog, includes the following components:

•Funded - Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts.

•Unfunded - Unfunded backlog represents the revenue value of firm orders for products and services under existing contracts for which funding has not yet been appropriated less funding previously recognized on these contracts.

The following table summarizes the value of our total backlog as of March 31, 2022, incorporating both funded and unfunded components:


Backlog:	March 31, 2022
(Dollars in millions)
Total Backlog	$	2,995

We expect to recognize approximately 53% of our March 31, 2022 backlog as revenue over the next nine months, with the remainder to be recognized thereafter.

Disaggregation of Revenue

ASC: ASC revenue is primarily derived from U.S. government development and production contracts and is generally recognized over time using the POC cost-to-cost method. We disaggregate ASC revenue by geographical region, customer relationship and contract type. We believe these categories best depict how the nature, amount, timing and uncertainty of ASC revenue and cash flows are affected by economic factors:

Other intangible assets mainly refer to the fair value of existing customer contractual relationships attributable to the acquired business and patents which are being amortized over their respective lives. The fair value of intangible assets typically is determined, as of the date of acquisition, based on estimates and judgments regarding expectations for the estimated future after-tax earnings and cash flows (including cash flows for working capital) arising from backlog and follow-on sales to the customer over their estimated lives, including the probability of expected future contract renewals and sales, less a contributory assets charge, all of which is discounted to present value.

The following disclosure presents certain information regarding the Company's intangible assets as of March 31, 2022 and December 31, 2021. All intangible assets are being amortized over their estimated useful lives, as indicated below, with no estimated residual values.

Total long-term debt	$	354	$	352

________________

(1)The Company’s debt with related parties consists of two term loans and a working capital credit facility with US Holding, as described below.

Term Loans

In January 2009, the Company entered into a credit agreement with its ultimate parent company, Finmeccanica S.p.A. (presently Leonardo S.p.A.) in the amount of $2 billion (the “2009 Credit Agreement”). The 2009 Credit Agreement was subsequently assigned to US Holding and has a maturity of November 30, 2023. The 2009 Credit Agreement provides for a term loan bearing interest at a rate of 7.5%, with interest payments due semi-annually on June 20 and December 20 in each year (the “7.5% Term loan”). The outstanding balance of the 7.5% Term loan at March 31, 2022 and December 31, 2021 was $139 million. The fair value of this term loan at March 31, 2022 and December 31, 2021 was $176 million and $182 million, respectively; however the Company has the ability to prepay the outstanding principal balance at the carrying amount without penalty.

In June 2017, the Company entered into an unsecured term loan with US Holding in the principal amount of $137.5 million, the proceeds of which were used to finance the acquisition of Daylight Solutions, Inc. (the “Daylight Term Loan”). The Daylight Term Loan had an outstanding balance of $78 million at March 31, 2022 and December 31, 2021 which approximates its fair value. The Daylight Term Loan matures on October 15, 2024. The

Daylight Term Loan has an interest rate of 5.0%, with interest payments due semi-annually on April 15 and October 15.

Credit Facilities

The 2009 Credit Agreement provides for a revolving credit facility available for working capital needs of the Company (the “Revolving Credit Facility”). As of March 31, 2022 and December 31, 2021, the Revolving Credit Facility had a credit limit of $450 million and an interest rate of LIBOR plus 3.5%. There is a commitment fee of 0.25% applied to the unused balance of the Revolving Credit Facility and there are no compensating balance requirements. The outstanding balance as of March 31, 2022 was $150 million and there was no balance on the Revolving Credit Facility as of December 31, 2021.

The Company also maintains uncommitted working capital credit facilities with certain financial institutions in the aggregate of $65 million at March 31, 2022 and December 31, 2021, respectively (the “Financial Institution Credit Facilities”). The Financial Institution Credit Facilities are guaranteed by Leonardo S.p.A. The primary purpose of the Financial Institution Credit Facilities is to support standby letter of credit issuances on contracts with customers and also includes a revolving facility with a maximum borrowing limit of $15 million, which bears interest at LIBOR plus 0.5%. At March 31, 2022 and December 31, 2021, there was no balance outstanding on the revolving facility. The Company had letters of credit outstanding of approximately $29 million and $35 million as of March 31, 2022 and December 31, 2021, which reduces the available capacity of the Financial Institution Credit Facilities by an equal amount.

Short-term Borrowings

As of March 31, 2022 and December 31, 2021, the Company recognized $9 million and $15 million, respectively, collected on behalf of the buyers of our trade receivables pursuant to our factoring arrangements as short-term borrowings and current portion of long-term debt in the Consolidated Balance Sheet, which approximates its fair value. Refer to Note 3: Accounts Receivable for more information.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Retirement Benefits [Abstract]

Pension and Other Postretirement Benefits

Retirement Plan Summary Information

The Company maintains multiple pension plans, both contributory and non-contributory, covering employees at certain locations. Eligibility requirements for participation in the plans vary, and benefits generally are based on the participant's compensation and years of service, as defined in the respective plan. The Company's funding policy generally is to contribute in accordance with cost accounting standards that affect government contractors, subject to the Tax Code and regulations thereunder. Plan assets are invested primarily in equities, bonds (both corporate and U.S. government), U.S. government-sponsored entity instruments, cash and cash equivalents and real estate.

The Company also provides postretirement medical benefits for certain retired employees and dependents at certain locations. Participants are eligible for these benefits when they retire from active service and meet the eligibility requirements for the Company's postretirement benefit plans. The Company's contractual arrangements with the U.S. government provide for the recovery of contributions to a Voluntary Employees' Beneficiary Association (“VEBA”) trust and, for non-funded plans, recovery of claims on a pay-as-you-go basis, subject to the Tax Code and regulations thereunder, with the retiree generally paying a portion of the costs through contributions, deductibles and coinsurance provisions.

The Company also maintains certain non-contributory and unfunded supplemental retirement plans. Eligibility for participation in the supplemental retirement plans is limited, and benefits generally are based on the participant's compensation and/or years of service.

The following table summarizes the components of net periodic benefit cost for the Company's pension, postretirement and supplemental retirement plans for the three months ended March 31,:


	Defined Benefit Pension Plans				Postretirement Benefit Plan				Supplemental Retirement Plans
(Dollars in millions)	March 31, 2022		March 31, 2021		March 31, 2022		March 31, 2021		March 31, 2022		March 31, 2021

Settlement expense (income)	$	1	$	—	$	—	$	—	$	—	$	—
Net periodic benefit cost	$	1	$	—	$	—	$	—	$	—	$	—

The expected long-term return on plan assets assumption represents the average rate that the Company expects to earn over the long-term on the assets of the Company's benefit plans, including those from dividends, interest income and capital appreciation. The assumption has been determined based on expectations regarding future rates of return for the plans' investment portfolio, with consideration given to the allocation of investments by asset class and historical rates of return for each individual asset class.

Pension related expenses are reflected in the Total costs of revenues and General and administrative expenses on the Consolidated Statement of Earnings (unaudited).

A one percentage increase or decrease in healthcare trend rates in the table above would have an insignificant impact to our service and interest cost and the postretirement medical obligations.

From time to time we are subject to certain legal proceedings and claims in the ordinary course of business. These matters are subject to many uncertainties and it is possible that some of these matters ultimately could be decided, resolved or settled in a manner adverse to us. Although the precise amount of liability that may result from these matters is not ascertainable, the Company believes that any amounts exceeding the Company's recorded accruals should not materially adversely affect the Company's financial condition or liquidity. It is possible, however, that the ultimate resolution of those matters could result in a material adverse effect on the Company's results of operations and/or cash flows from operating activities for a particular reporting period. We establish reserves for specific legal matters when we determine that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable.

Some environmental laws, such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (also known as “CERCLA” or the “Superfund law”) and similar state statutes, can impose liability upon former owners or operators for the entire cost of investigating and remediating contaminated sites regardless of the lawfulness of the original activities that led to the contamination. In July 2000, an entity which later became a subsidiary of the Company received a Section 104(e) Request for Information (“RFI”) from the National Park Service (“NPS”), pursuant to CERCLA, regarding the presence of radioactive material at a site within a national park, which site was operated by an alleged predecessor to our subsidiary over 50 years ago. Following the subsidiary’s response to the RFI, the NPS directed it and another alleged former operator to perform an Engineering Evaluation and Cost Analysis (“EE/CA”) of a portion of the site. The Company’s subsidiary made a good faith offer to conduct an alternative EE/CA work plan, but the NPS rejected this offer and opted to perform the EE/CA itself. The NPS previously posted its intention to open a formal public comment period regarding the EE/CA at the end of 2019. To the Company’s knowledge, the EE/CA has not been released and a public comment period has yet to be opened.

Following completion of the EE/CA, the NPS may seek reimbursement for its investigative and remedial efforts to date, or direct one or more of the potentially responsible parties to perform any remediation that may be required by CERCLA or may enter an alternative dispute resolution proceeding to attempt to resolve each party’s share. In addition, the NPS may seek to recover damages for loss of use of certain natural resources. The Company believes that it has legitimate defenses to its subsidiary’s potential liability and that there are other potentially responsible parties for the environmental conditions at the site, including the U.S. government as owner, operator and arranger at the site. The potential liability associated with this matter could change substantially due to such factors as additional information on the nature or extent of contamination, methods of remediation that might be recommended or required, changes in the apportionment of costs among the responsible parties, whether the NPS seeks to recover additional damages, whether the NPS’s plans to investigate additional areas to identify a need for further remedial action for which the Company may be identified as a potentially responsible party and other actions by governmental agencies or private parties.

The Company has recorded its best estimate of damages and its share of remediation costs related to the site to reflect what we and our advisors reasonably believe we would be liable for based on the current information and circumstances of the claim, exclusive of other potential liabilities that may be asserted in the future.

In the performance of our contracts we routinely request contract modifications that require additional funding from the customer. Most often, these requests are due to customer-directed changes in the scope of work. While we are entitled to recovery of these costs under our contracts, the administrative process with our customer may be protracted. Based on the circumstances, we periodically file requests for equitable adjustment (“REAs”) that are sometimes converted into claims. In some cases, these requests are disputed by our customer. We believe our outstanding modifications, REAs and other claims will be resolved without material impact to our results of operations, financial condition or cash flows.

As a government contractor, with customers including the U.S. government as well as various state and local government entities, the Company may be subject to audits, investigations and claims with respect to its contract performance, pricing, costs, cost allocations and procurement practices. Additionally, amounts billed under such contracts, including direct and indirect costs, are subject to potential adjustments before final settlement.

Management believes that adequate provisions for such potential audits, investigations, claims and contract adjustments, if any, have been made in the financial statements.

Product Warranties

Product warranty costs generally are accrued in proportion to product revenue realized in conjunction with our over-time revenue recognition policy. Product warranty expense is recognized based on the term of the product warranty, generally one year to three years, and the related estimated costs, considering historical claims expense. Accrued warranty costs are reduced as these costs are incurred and as the warranty period expires, and otherwise

may be modified as specific product performance issues are identified and resolved. The following is a summary of changes in the product warranty balances during the period ended March 31, 2022:

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Under our current proxy agreement, DRS remains largely independent from the Parent. Additionally, the Company provides services related to the U.S. interface for the Parent and its other affiliates. These services include financial, tax, trade compliance, marketing and communications and legal. The Company also has related-party sales with the Parent and its other affiliates that occur in the regular course of business. Related-party sales for these transactions are included in revenues and were $1 million and $2 million for the periods ended March 31, 2022 and March 31, 2021, respectively. The receivables related to these transactions with the Parent and its other affiliates of $3 million and $2 million, respectively, and payables of $2 million and $1 million, respectively, are included in accounts receivable and accounts payable in our Consolidated Balance Sheet as of March 31, 2022 and December 31, 2021. The Company entered into a Surplus Treasury Agreement with US Holding (the “Surplus Agreement”) in December 2019. The Surplus Agreement allows the Company to advance excess funds to US Holding when funds are available. The advances bear interest at LIBOR plus between 5 and 20 basis points depending on the tenor of the advance. As of March 31, 2022 and December 31, 2021 the Company did not advance any amount to US Holdings. The Company entered into Tax Allocation Agreement with US Holding, dated as of November 16, 2020. Refer to Note 1: Summary of Significant Accounting Policies for more information. The Company’s capital structure consists of related party lending instruments as described in Note 10: Debt

Segment Reporting [Abstract]

Segment Information

Operating segments represent components of an enterprise for which separate financial information is available that is regularly reviewed by the CODM in determining how to allocate resources and assess performance. Our Chief Executive Officer is our CODM and he uses a variety of measures to assess the performance of the Company as a whole, depending on the nature of the activity. Beginning in the first quarter of 2022, the Company’s operating and reportable segments were revised into two reportable segments, ASC and IMS, to align our market strategy and capital allocation decision making with our operating structure. Prior year information was revised to reflect the new segment structure. All other operations, which consists primarily of DRS Corporate Headquarters and certain non-operating subsidiaries of the Company, are grouped in Corporate & Eliminations.

We primarily use Adjusted EBITDA to manage the Company and allocate resources. Adjusted EBITDA of our business segments includes our net earnings before income taxes, amortization of acquired intangible assets, depreciation, restructuring costs, interest, transaction costs related to an anticipated offering of securities, acquisition and divestiture related expenses, foreign exchange, COVID-19 response costs, non-service pension expenditures and other one-time non-operational events. Adjusted EBITDA is used to facilitate a comparison of the ordinary, ongoing and customary course of our operations on a consistent basis from period to period and provide an additional understanding of factors and trends affecting our business segments. This measure assists the CODM in assessing segment operating performance consistently over time without the impact of our capital structure, asset base and items outside the control of the management team and expenses that do not relate to our core operations.

Certain information related to our segments for the periods ended March 31, 2022 and March 31, 2021 is presented in the following tables. Consistent accounting policies have been applied by all segments within the Company, within all reporting periods. A description of our reportable segments as of March 31, 2022 and March 31, 2021 has been included in Note 1: Summary of Significant Accounting Policies. Transactions between segments generally are negotiated and accounted for under terms and conditions that are similar to other government and commercial contracts; however, these intercompany transactions are eliminated in consolidation.

Total revenues and intersegment revenues by segment for the periods ended March 31, 2022 and, March 31, 2021 consists of the following:

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2022
Accounting Policies [Abstract]
Segment Reporting	Advanced Sensing and Computing (“ASC”) The ASC segment provides sensing and computing systems and subsystem solutions to the U.S. military and allied nations focused on solving the most complex threat dynamics facing our service men and women today. We provide world class sensing products in all warfighting domains along with the computation systems to provide situational understanding. Our technologies and products are deployed on nearly all military platforms across land, sea, air, cyberspace, and space on individual soldiers, ground vehicles, ships, aircraft, and satellites. We have market leading capabilities in electro-optic and infrared imaging, advanced lasers, electronic warfare and cyber, communications, and computing in these domains. Integrated Mission Systems (“IMS”) The IMS segment provides critical force protection, platform integration, transportation and logistics and power conversion and propulsion systems to the U.S. military and its allies. Our force protection systems provide much needed protection for our service members and military assets from evolving and proliferating threats and include advanced solutions for counter-unmanned aerial systems, short-range air defense systems and active protection systems on ground vehicles. Additionally, we provide power conversion and propulsion systems for the U.S. Navy’s top priority shipbuilding programs, building on our legacy of providing power components and systems for nearly all naval combat vessels for three decades, positioning us to continue as a leading provider of electrical ship propulsion systems and components for the U.S. Navy and its allies. Other The Company separately presents the unallocable costs associated with corporate functions and certain non-operating subsidiaries of the Company as Corporate & Eliminations.
Basis of Presentation	Basis of presentation The accompanying unaudited 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 and contain all adjustments, which are of a normal and recurring nature, considered necessary by management to present fairly the financial position, results of operations and cash flows for the periods presented. Interests in 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. Certain prior year amounts have been reclassified to conform to current year presentation. Interim Financial Statements. The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These rules and regulations permit some of the information and footnote disclosures included in financial statements prepared in accordance with U.S. GAAP to be condensed or omitted. These unaudited Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements as of and for the year ended December 31, 2021 included in our Annual Report on Form 10-K for the year end December 31, 2021, filed with the SEC on March 28, 2022.
Use of Estimates	Use of EstimatesThe 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, long-lived assets and intangible assets, 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.
Revenue Recognition and Cost of Revenues	Revenue RecognitionOn January 1, 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, and the related amendments of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, which supersedes most previous U.S. GAAP revenue recognition guidance. As of the date of adoption, we elected the practical expedient for contract modifications, which allows us to assume that the terms of the contract that existed at the beginning of the earliest period presented have been in place since the inception of the contract on the basis that it is not practical to separately evaluate the effects of all prior contract modifications. 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 (“POC”) cost-to-cost method of accounting. 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 customer based on control transferred to the customer.Cost of RevenuesCost 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.The Company recognizes revenue for each separately identifiable performance obligation in a contract representing an obligation to transfer a distinct good or service to a customer. In most cases, goods and services provided under the Company’s contracts are accounted for as single performance obligations due to the complex and integrated nature of our products and services. These contracts generally require significant integration of a group of goods and/or services to deliver a combined output. In some contracts, the Company provides multiple distinct goods or services to a customer. In those cases, the Company accounts for the distinct contract deliverables as separate performance obligations and allocates the transaction price to each performance obligation based on its relative standalone selling price, which is generally estimated using cost plus a reasonable margin. We classify revenues as products or services on our Consolidated Statements of Earnings based on the predominant attributes of the performance obligations. While the Company provides warranties on certain contracts, we typically do not provide for services beyond standard assurances and therefore do not consider standard warranties to be separate performance obligations. Typically we enter into three types of contracts: fixed-price contracts, cost-plus contracts and T&M contracts (cost-plus contracts and T&M contracts are aggregated below as flexibly priced contracts). The majority of our total revenues are derived from fixed-price contracts; refer to the revenue disaggregation disclosures that follow. For fixed-price contracts, customers agree to pay a fixed amount, negotiated in advanced for a specified scope of work. For cost-plus contracts, typically we are reimbursed for allowable or otherwise defined total costs (defined as cost of revenues plus allowable general and administrative expenses) incurred, plus a fee. The contracts may also include incentives for various performance criteria, including quality, timeliness and cost-effectiveness. In addition, costs are generally subject to review by customers and regulatory audit agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract. T&M contracts provide for reimbursement of labor hours expended at a contractual fixed labor rate per hour, plus the actual costs of material and other direct non-labor costs. The fixed labor rates on T&M contracts include amounts for the cost of direct labor, indirect contract costs and profit. Estimating the transaction price for an arrangement requires judgment and is based on expected results which are determined using the Company’s historical data. We estimate that the revenue that we expect to be entitled to receive from a customer to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. Revenue from contracts with customers is recognized when the performance obligations are satisfied through the transfer of control over the good or service to the customer, which may occur either over time or at a point in time. Revenues for the majority of our contracts are measured as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion (the "cost-to-cost method"). We believe this is an appropriate measure of progress toward satisfaction of performance obligations as this measure most accurately depicts the progress of our work and transfer of control to our customers. Due to the long-term nature of many of our contracts, developing the estimated total cost at completion and total transaction price often requires judgment. Factors that must be considered in estimating the cost of the work to be completed include the nature and complexity of the work to be performed, subcontractor performance and the risk and impact of delayed performance. After establishing the estimated total cost at completion, we follow a standard Estimate at Completion (“EAC”) process in which we review the progress and performance on our ongoing contracts at least quarterly. Adjustments to original estimates for a contract's revenue, estimated costs at completion and estimated profit or loss often are required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change and are also required if contract modifications occur. When adjustments in estimated total costs at completion or in estimated total transaction price are determined, the related impact on revenue and operating income are recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Any anticipated losses on these contracts are fully recognized in the period in which the losses become evident. Conversely, if the requirements for the recognition of contracts over time are not met, revenue is recognized at a point in time when control transfers to the customer, which is generally upon transfer of title. In such cases, the production that is in progress and costs that will be recognized at a future point in time are reported within "inventories". Costs to obtain a contract are incremental direct costs incurred to obtain 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 specific anticipated contract (e.g., 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. Contract Assets and Liabilities The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheet. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities. The change in the balances of the Company’s contract assets and liabilities primarily results from timing differences between revenue recognition and customer billings and/or payments. Contract assets related to amounts withheld by customers until contract completion are not considered a significant financing component of our contracts because the intent is to protect the customers from our failure to satisfactorily complete our performance obligations. Payments received from customers in advance of revenue recognition (contract liabilities) are not considered a significant financing component of our contracts because they are utilized to pay for contract costs within a one-year period or are requested by us to ensure the customers meet their payment obligations. Value of Remaining Performance Obligations The value of remaining performance obligations, which we also refer to as total backlog, includes the following components: •Funded - Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts. •Unfunded - Unfunded backlog represents the revenue value of firm orders for products and services under existing contracts for which funding has not yet been appropriated less funding previously recognized on these contracts.
Research and Development Expenses	Research and Development ExpensesWe 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. Substantially all customer funded R&D costs are charged to cost of revenues as incurred.
Foreign Currency	Foreign CurrencySignificant 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 the periods ended March 31, 2022 and March 31, 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 earnings.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash 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.
Accounts Receivable	Accounts ReceivableAccounts receivable consist of amounts billed and 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.
Inventories	InventoriesInventories 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.
Property, Plant and Equipment	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 Sheet, 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.
Goodwill	GoodwillOn January 1, 2018, we early adopted ASU 2017-04, Intangibles ‐ Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment. The standard simplifies the measurement of goodwill impairment by eliminating the requirement that an entity compute the implied fair value of goodwill based on the fair values of its assets and liabilities to measure impairment. Instead, goodwill impairment will be measured as the difference between the fair value and the carrying value of the reporting unit. 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 seven reporting units at both March 31, 2022 and December 31, 2021. The annual impairment test is conducted as of December 31. The Company did not identify any triggering event during the quarters ended March 31, 2022 or March 31, 2021.
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.Other intangible assets mainly refer to the fair value of existing customer contractual relationships attributable to the acquired business and patents which are being amortized over their respective lives. The fair value of intangible assets typically is determined, as of the date of acquisition, based on estimates and judgments regarding expectations for the estimated future after-tax earnings and cash flows (including cash flows for working capital) arising from backlog and follow-on sales to the customer over their estimated lives, including the probability of expected future contract renewals and sales, less a contributory assets charge, all of which is discounted to present value.
Long-Lived Assets	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.
Derivative Financial Instruments	Derivative Financial InstrumentsThe Company does not use derivative financial instruments for trading purposes. All derivative instruments are carried on the Consolidated Balance Sheet as either assets or liabilities at fair value. The classification of gains and losses resulting from changes in the fair values of derivatives depends on the intended use of the derivative and its resultant designation. The Company had no significant derivative or hedging instruments for the periods presented.
Pension and Other Postretirement Benefits	Pension and Other Postretirement BenefitsThe 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. The Company maintains multiple pension plans, both contributory and non-contributory, covering employees at certain locations. Eligibility requirements for participation in the plans vary, and benefits generally are based on the participant's compensation and years of service, as defined in the respective plan. The Company's funding policy generally is to contribute in accordance with cost accounting standards that affect government contractors, subject to the Tax Code and regulations thereunder. Plan assets are invested primarily in equities, bonds (both corporate and U.S. government), U.S. government-sponsored entity instruments, cash and cash equivalents and real estate. The Company also provides postretirement medical benefits for certain retired employees and dependents at certain locations. Participants are eligible for these benefits when they retire from active service and meet the eligibility requirements for the Company's postretirement benefit plans. The Company's contractual arrangements with the U.S. government provide for the recovery of contributions to a Voluntary Employees' Beneficiary Association (“VEBA”) trust and, for non-funded plans, recovery of claims on a pay-as-you-go basis, subject to the Tax Code and regulations thereunder, with the retiree generally paying a portion of the costs through contributions, deductibles and coinsurance provisions. The Company also maintains certain non-contributory and unfunded supplemental retirement plans. Eligibility for participation in the supplemental retirement plans is limited, and benefits generally are based on the participant's compensation and/or years of service. The expected long-term return on plan assets assumption represents the average rate that the Company expects to earn over the long-term on the assets of the Company's benefit plans, including those from dividends, interest income and capital appreciation. The assumption has been determined based on expectations regarding future rates of return for the plans' investment portfolio, with consideration given to the allocation of investments by asset class and historical rates of return for each individual asset class.Pension related expenses are reflected in the Total costs of revenues and General and administrative expenses on the Consolidated Statement of Earnings (unaudited).
Income Taxes	Income Taxes We and US Holding have 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 provides 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, 2021 and each subsequent year in which the parties are members of a group (whether federal or state). The agreement also provides 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 have 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. We calculate the provision for incomes taxes during interim periods by applying an estimate of our annual effective tax rate for the full year to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items. 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. 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.
Earnings Per Share	Earnings Per ShareBasic 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 stock-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. The consolidated financial statements have been adjusted to reflect the forward stock split for all periods presented. There were 100 shares and 145 million basic and diluted common shares outstanding before and after the forward stock split, respectively, for all periods presented.
Fair Value Measurements	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.
Financial Instruments	Financial InstrumentsOur 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 Sheet at carrying value, which other than the 7.5% Term loan due November 30, 2023, approximate fair value.
Acquisitions	AcquisitionsOur 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.
Investments	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 Sheet. 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’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	Variable Interest Entities The Company occasionally forms joint ventures and/or enters into arrangements with special purpose limited liability companies for the purpose of bidding and executing on specific projects. The Company analyzes each such arrangement to determine whether it represents a variable interest entity (“VIE”). If the arrangement is determined to be a VIE, the Company assesses whether it is the primary beneficiary of the VIE and if it is, consequently required to consolidate the VIE. The Company did not have any investment in VIEs for the periods presented.
