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.S.p.A (hereinafter, “Leonardo S.p.A.,” or “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 and communications, force protection and electrical power conversion and propulsion.

These capabilities directly align with our 2 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%78% and 86%82% of our total revenues as an end-user for the periods ended March 31,second quarter and first six months of 2022, respectively, and March 31, 2021, respectively.85% for the second quarter and first six months of 2021. Specific international and commercial market opportunities exist within these segments and make up approximately 15%22% and 14%18% of our total revenues for the periods ended March 31,second quarter and first six months of 2022, respectively, and March 31, 2021, respectively.15% for the second quarter and first half of 2021. Our 2 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”).

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.

We have market leading capabilities in electro-optic and infrared imaging, advanced lasers, electronic warfare and cyber, communications, and computing in these domains.

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.

The Company separately presents the unallocable costs associated with corporate functions and certain non-operating subsidiaries of the Company as Corporate & Eliminations.

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. Interests in joint ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts significant influence, the Company applies the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to current year presentation.

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 Annualfiled as Exhibit 99.1 to the Current Report on Form 10-K for the year end December 31, 2021,8-K filed with the SEC on March 28,August 2, 2022.

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.

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,

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 products, solutions, and 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

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,second quarter and first six months of 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 include cash on hand, deposits with banks or other short-term, highly liquid investments with original maturities of three months or less.

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.

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 does not use derivative financial instruments for trading purposes. All derivative instruments are carried on the Consolidated Balance SheetSheets 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.

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, 20212020 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

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.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.

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.

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

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.

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 anyAs previously announced, on June 21, 2022, we entered into the Agreement and Plan of Merger, dated as of June 21, 2022 (the “merger agreement”), by and among the Company, RADA Electronic Industries Ltd (“RADA”) and Blackstart Ltd, a company organized under the laws of the periods presented.State of Israel and a wholly owned subsidiary of DRS (“Merger Sub”). Upon the terms and subject to the conditions of the merger agreement, and in accordance with the Companies Law, 5759-1999, of the State of Israel, at the effective time of the merger contemplated by the merger agreement (the “merger”), Merger Sub will be merged with and into RADA, with RADA as the surviving company of the merger and thereby becoming a wholly owned subsidiary of DRS. At the effective time of the merger (the “effective time”), each ordinary share of RADA, par value New Israeli Shekel 0.03 per share (“RADA shares”), issued and outstanding immediately prior to the effective time will be converted into and become exchangeable for 1 share of common stock of DRS, par value $0.01 per share (“DRS common stock”). Immediately prior to the effective time, the shares of DRS common stock held by US Holding, the current sole stockholder of DRS, will be split (rounded up to the nearest whole share), as necessary, such that, immediately following the effective time and the issuance of the shares of DRS common stock to holders of RADA shares and the treatment of options to purchase RADA shares: (A) US Holding will hold 80.5% of the issued and outstanding shares of DRS common stock on a fully diluted basis (with US Holding’s ownership percentage including 50% of any awards or other equity interests that DRS may issue pursuant to entitlements under any grants of certain one-time special awards of restricted stock units (the “One-Time Awards”) and the foregoing percentage calculation excluding any awards or other equity interests that DRS may issue pursuant to entitlements under the DRS’s long term incentive plan and 50% of any awards or other equity interests that DRS may issue pursuant to entitlements in

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.Sheets. Significant influence typically exists if we have a 20% to 50% ownership interest in the investee. Under this method of accounting, our share of the net earnings or losses of the investee is included in operating profit in other income, net on our Consolidated Statements of Earnings since the activities of the investee are closely aligned with the operations of the business segment holding the investment. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is therefore recorded during the current period.

The Company’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.

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.

On March 21, 2022, the Company entered into a definitive agreement to sell its Global Enterprise Solutions (GES)(“GES”) business to SES Government Solutions, Inc., a wholly-owned subsidiary of SES S.A., for $450 million in cash. The transaction was completed on August 1, 2022 and resulted in proceeds of $427 million. We are in the process of finalizing the accounting for the transaction and will report the gain on the transaction in the third quarter. GES, which iswas 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,June 30, 2022, the assets and liabilities related to GES arewere reported on the Consolidated Balance SheetSheets as Held for Sale.

In February 2022, the Leonardo DRSCompany’s Board of Directors approved the strategic initiative to divest of the Company’s interest in AAC.Advanced Acoustic Concepts (“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)AAC for $56 million to Thales Defense & Security, Inc (TDSI)Inc., the minority partner in the Joint Venture.joint venture. The sale is pending regulatory approvaltransaction was completed on July 8, 2022 and is beingresulted in proceeds of

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

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 customersclients 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:

The impacts noted above are attributed primarily to changes in our firm-fixed-price development type programs. AsThey consist of changes happen in the designdesigns required to achieve contractual specifications those changes often resultfor fixed priced development programs and inflationary impacts on certain naval production programs that resulted in a change 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.

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.Sheets. 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.

Revenue recognized in the three-and six-month periods ending March 31,ended June 30, 2022 that was included in the contract liability balance at the beginning of each period was $33 million and March 31,$107 million, respectively. Revenue recognized in the three- and six-month periods ended June 30, 2021 that was included in the contract liability balance at the beginning of each period was $74$20 million and $69$89 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.

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

We expect to recognize approximately 53%39% of our March 31,June 30, 2022 backlog as revenue over the next ninesix months, with the remainder to be recognized thereafter.

We believe these categories best depict how the nature, amount, timing and uncertainty of IMS revenue and cash flows are affected by economic factors:

________________

Accounts receivable represent amounts billed and currently due from customers. Payment is typically received from our customers either at periodic intervals (e.g., biweekly, or monthly) or upon achievement of contractual milestones.

Accounts receivable consist of the following:

The Company maintains certain agreements with financial institutions to sell certain trade receivables. Receivables are derecognized in their entirety when sold, and the Company’s continuing involvement in the sold receivables is limited to their servicing, for which the Company receives a fee commensurate with the service provided. Pursuant to the servicing agreements, the Company collected approximately $9$1 million and $15 million at March 31,June 30, 2022 and December 31, 2021, respectively, of these sold receivables that had not yet been remitted to the financial institutions. These unremitted amounts collected on behalf of the financial institutions are included within short-term borrowings and current portion of long-term debt in the Consolidated Balance Sheet.Sheets.

Inventories consists of the following:

Property, plant and equipment by major asset class consists of the following:

Depreciation expense related to property, plant and equipment was $13$14 million and $27 million for the three- and six-month periods ended June 30, 2022, and $12 million and $24 million for the three- and six-month periods ended March 31, 2022 and March 31,June 30, 2021, respectively.

A summary of significant other liabilities by balance sheet caption follows:

Changes in the carrying amount of goodwill by reportable segment are as follows:

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,June 30, 2022 and December 31, 2021. All intangible assets are being amortized over their estimated useful lives, as indicated below, with no estimated residual values.

Amortization expense related to intangible assets was $2 million and $4 million for the three- and six-month periods ended March 31,June 30, 2022 and March 31,was $2 million and $4 million for the three- and six-month periods ended June 30, 2021.

Customer relationships are amortized on a straight-line basis over their estimated useful lives of 10 to 15 years. Patents and licenses are amortized on a straight-line basis over their estimated useful lives of 5 to 10 years.

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at March 31,as of June 30, 2022 and December 31, 2021 isare as follows:

The Company’s debt consists of the following:

________________

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,June 30, 2022 and December 31, 2021 was $139 million. The fair value of this term loan at March 31,June 30, 2022 and December 31, 2021 was $176$142 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

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,June 30, 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,June 30, 2022 was $150$110 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,June 30, 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,June 30, 2022 and December 31, 2021, there was no balance outstanding on the revolving facility. The Company had letters of credit outstanding of approximately $29$31 million and $35 million as of March 31,June 30, 2022, and December 31, 2021, respectively, which reduces the available capacity of the Financial Institution Credit Facilities by an equal amount.

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.
