Accounting Policies [Abstract]
Organization and Significant Accounting Policies	Organization and Significant Accounting Policies Organization – We are a global security and aerospace company principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. We also provide a broad range of management, engineering, technical, scientific, logistics, system integration and cybersecurity services. We serve both U.S. and international customers with products and services that have defense, civil and commercial applications, with our principal customers being agencies of the U.S. Government. As described in “Note 3 – Information on Business Segments”, we operate in four business segments: Aeronautics, MFC, RMS and Space. Basis of presentation – These consolidated financial statements include the accounts of subsidiaries we control and variable interest entities if we are the primary beneficiary. We eliminate intercompany balances and transactions in consolidation. We classify certain assets and liabilities as current utilizing the duration of the related contract or program as our operating cycle, which is generally longer than one year. This primarily impacts receivables, contract assets, inventories, and contract liabilities. We classify all other assets and liabilities based on whether the asset will be realized or the liability will be paid within one year. Effective January 1, 2023, we no longer consider amortization expense related to purchased intangible assets when evaluating the operating performance of our business segments. As a result, intangible asset amortization expense, which was previously included in segment operating profit, is now reported in unallocated corporate expense within total consolidated operating profit. This change has no impact on our consolidated operating results. Management believes this updated presentation better aligns with how the business is viewed and managed and will provide better insights into business segment performance. This change has been applied to the amounts in this Form 10-K, including amounts for 2022 and 2021. See “Note 3 – Information on Business Segments” for further information regarding the impact of this change on our current and prior period segment operating profit. Use of estimates – We prepare our consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP). In doing so, we are required to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base these estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates. Significant estimates inherent in the preparation of our consolidated financial statements include, but are not limited to, accounting for sales and cost recognition; postretirement benefit plans; environmental liabilities and assets for the portion of environmental costs that are probable of future recovery; evaluation of goodwill, intangible assets, investments and other assets for impairment; income taxes including deferred income taxes; fair value measurements; and contingencies. Revenue Recognition – The majority of our net sales are generated from long-term contracts with the U.S. Government and international customers (including foreign military sales (FMS) contracted through the U.S. Government) for the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. For certain contracts that meet the foregoing requirements, primarily international direct commercial sale contracts, we are required to obtain certain regulatory approvals. In these cases, we recognize revenue when it is probable that we will receive regulatory approvals based upon all known facts and circumstances. We provide our products and services under fixed-price and cost-reimbursable contracts. Under fixed-price contracts, we agree to perform the specified work for a pre-determined price. To the extent our actual costs vary from the estimates upon which the price was negotiated, we will generate more or less profit or could incur a loss. Some fixed-price contracts have a performance-based component under which we may earn incentive payments or incur financial penalties based on our performance. Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract plus a fee up to a ceiling based on the amount that has been funded. Typically, we enter into three types of cost-reimbursable contracts: cost-plus-award-fee, cost-plus-incentive-fee, and cost-plus-fixed-fee. Cost-plus-award-fee contracts provide for an award fee that varies within specified limits based on the customer’s assessment of our performance against a predetermined set of criteria, such as targets based on cost, quality, technical and schedule criteria. Cost-plus-incentive-fee contracts provide for reimbursement of costs plus a fee, which is adjusted by a formula based on the relationship of total allowable costs to total target costs (i.e., incentive based on cost) or reimbursement of costs plus an incentive to exceed stated performance targets (i.e., incentive based on performance). Cost-plus-fixed-fee contracts provide a fixed fee that is negotiated at the inception of the contract and does not vary with actual costs. We assess each contract at its inception to determine whether it should be combined with other contracts. When making this determination, we consider factors such as whether two or more contracts were negotiated and executed at or near the same time or were negotiated with an overall profit objective. If combined, we treat the combined contracts as a single contract for revenue recognition purposes. We evaluate the products or services promised in each contract at inception to determine whether the contract should be accounted for as having one or more performance obligations. The products and services in our contracts are typically not distinct from one another due to their complex relationships and the significant contract management functions required to perform under the contract. Accordingly, our contracts are typically accounted for as one performance obligation. In limited cases, our contracts have more than one distinct performance obligation, which occurs when we perform activities that are not highly complex or interrelated or involve different product lifecycles. Significant judgment is required in determining performance obligations, and these decisions could change the amount of revenue and profit recorded in a given period. We classify net sales as products or services on our consolidated statements of earnings based on the predominant attributes of the performance obligations. We determine the transaction price for each contract based on the consideration we expect to receive for the products or services being provided under the contract. For contracts where a portion of the price may vary (e.g. awards, incentive fees and claims), we estimate variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. We analyze the risk of a significant revenue reversal and if necessary constrain the amount of variable consideration recognized in order to mitigate this risk. At the inception of a contract we estimate the transaction price based on our current rights and do not contemplate future modifications (including unexercised options) or follow-on contracts until they become legally enforceable. Contracts are often subsequently modified to include changes in specifications, requirements or price, which may create new or change existing enforceable rights and obligations. Depending on the nature of the modification, we consider whether to account for the modification as an adjustment to the existing contract or as a separate contract. Generally, modifications to our contracts are not distinct from the existing contract due to the significant integration and interrelated tasks provided in the context of the contract. Therefore, such modifications are accounted for as if they were part of the existing contract and recognized as a cumulative adjustment to revenue. For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation based on the estimated standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount we would sell the product or service to a customer on a standalone basis (i.e., not bundled with any other products or services). Our contracts with the U.S. Government, including FMS contracts, are subject to the Federal Acquisition Regulations (FAR) and the price is typically based on estimated or actual costs plus a reasonable profit margin. As a result of these regulations, the standalone selling price of products or services in our contracts with the U.S. Government and FMS contracts are typically equal to the selling price stated in the contract. For non-U.S. government contracts with multiple performance obligations, we evaluate whether the stated selling prices for the products or services represent their standalone selling prices. We primarily sell customized solutions unique to a customer’s specifications. When it is necessary to allocate the transaction price to multiple performance obligations, we typically use the expected cost plus a reasonable profit margin to estimate the standalone selling price of each product or service. We occasionally sell standard products or services with observable standalone sales transactions. In these situations, the observable standalone sales transactions are used to determine the standalone selling price. We recognize revenue as performance obligations are satisfied and the customer obtains control of the products and services. In determining when performance obligations are satisfied, we consider factors such as contract terms, payment terms and whether there is an alternative future use of the product or service. Substantially all of our revenue is recognized over time as we perform under the contract because control of the work in process transfers continuously to the customer. For most contracts with the U.S. Government and FMS contracts, this continuous transfer of control of the work in process to the customer is supported by clauses in the contract that give the customer ownership of work in process and allow the customer to unilaterally terminate the contract for convenience and pay us for costs incurred plus a reasonable profit. For most non-U.S. government contracts, primarily international direct commercial contracts, continuous transfer of control to our customer is supported because we deliver products that do not have an alternative use to us and if our customer were to terminate the contract for reasons other than our non-performance we would have the right to recover damages which would include, among other potential damages, the right to payment for our work performed to date plus a reasonable profit. For performance obligations to deliver products with continuous transfer of control to the customer, revenue is recognized based on the extent of progress towards completion of the performance obligation, generally using the percentage-of-completion cost-to-cost measure of progress for our contracts because it best depicts the transfer of control to the customer as we incur costs on our contracts. Under the percentage-of-completion cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs to complete the performance obligation(s). For performance obligations to provide services to the customer, revenue is recognized over time based on costs incurred or the right to invoice method (in situations where the value transferred matches our billing rights) as our customer receives and consumes the benefits. For performance obligations in which control does not continuously transfer to the customer, we recognize revenue at the point in time in which each performance obligation is fully satisfied. This coincides with the point in time the customer obtains control of the product or service, which typically occurs upon customer acceptance or receipt of the product or service, given that we maintain control of the product or service until that point. Backlog (i.e., unfulfilled or remaining performance obligations) represents the sales we expect to recognize for our products and services for which control has not yet transferred to the customer. It is converted into sales in future periods as work is performed or deliveries are made. For our cost-reimbursable and fixed-priced-incentive contracts, the estimated consideration we expect to receive pursuant to the terms of the contract may exceed the contractual award amount. The estimated consideration is determined at the outset of the contract and is continuously reviewed throughout the contract period. In determining the estimated consideration, we consider the risks related to the technical, schedule and cost impacts to complete the contract and an estimate of any variable consideration. Periodically, we review these risks and may increase or decrease backlog accordingly. As the risks on such contracts are successfully retired, the estimated consideration from customers may be reduced, resulting in a reduction of backlog without a corresponding recognition of sales. As of December 31, 2023, our ending backlog was $160.6 billion. We expect to recognize approximately 36% of our backlog over the next 12 months and approximately 62% over the next 24 months as revenue, with the remainder recognized thereafter. For arrangements with the U.S. Government and FMS contracts, we generally do not begin work on contracts until funding is appropriated by the customer. Billing timetables and payment terms on our contracts vary based on a number of factors, including the contract type. Typical payment terms under fixed-price contracts with the U.S. Government provide that the customer pays either performance-based payments (PBPs) based on the achievement of contract milestones or progress payments based on a percentage of costs we incur. Typical payment terms under cost-reimbursable contracts with the U.S Government provide for billing of allowable costs incurred plus applicable fee on a monthly or semi-monthly basis. For the majority of our international direct commercial contracts to deliver complex systems, we typically receive advance payments prior to commencement of work, as well as milestone payments that are paid in accordance with the terms of our contract as we perform. We recognize a liability for payments in excess of revenue recognized, which is presented as a contract liability on the balance sheet. The portion of payments retained by the customer until final contract settlement is not considered a significant financing component because the intent is to protect the customer from our failure to adequately complete some or all of the obligations under the contract. Payments received from customers in advance of revenue recognition are not considered to be significant financing components because they are used to meet working capital demands that can be higher in the early stages of a contract. For fixed-price and cost-reimbursable contracts, we present revenues recognized in excess of billings as contract assets on the balance sheet. Amounts billed and due from our customers under both contract types are classified as receivables on the balance sheet. Significant estimates and assumptions are made in estimating contract sales, costs, and profit. We estimate profit as the difference between estimated revenues and total estimated costs to complete the contract. At the outset of a long-term contract, we identify and monitor risks to the achievement of the technical, schedule and cost aspects of the contract, as well as our ability to earn variable consideration, and assess the effects of those risks on our estimates of sales and total costs to complete the contract. The estimates consider the technical requirements (e.g., a newly-developed product versus a mature product), the schedule and associated tasks (e.g., the number and type of milestone events) and costs (e.g., material, labor, subcontractor, overhead, general and administrative and the estimated costs to fulfill our industrial cooperation agreements, sometimes referred to as offset or localization agreements, required under certain contracts with international customers). The initial profit booking rate of each contract considers risks surrounding the ability to achieve the technical requirements, schedule and costs in the initial estimated total costs to complete the contract. Profit booking rates may increase during the performance of the contract if we successfully retire risks related to technical, schedule and cost aspects of the contract, which decreases the estimated total costs to complete the contract or may increase the variable consideration we expect to receive on the contract. Conversely, our profit booking rates may decrease if the estimated total costs to complete the contract increase or our estimates of variable consideration we expect to receive decrease. All of the estimates are subject to change during the performance of the contract and may affect the profit booking rate. When estimates of total costs to be incurred on a contract exceed total estimates of the transaction price, a provision for the entire loss is determined at the contract level and is recorded in the period in which the loss is evident, which we refer to as a reach-forward loss. Comparability of our segment sales, operating profit and operating margin may be impacted favorably or unfavorably by changes in profit booking rates on our contracts. Increases in the profit booking rates, typically referred to as favorable profit adjustments, usually relate to revisions in the estimated total costs to fulfill the performance obligations that reflect improved conditions on a particular contract. Conversely, conditions on a particular contract may deteriorate, resulting in an increase in the estimated total costs to fulfill the performance obligations and a reduction in the profit booking rate and are typically referred to as unfavorable profit adjustments. Increases or decreases in profit booking rates are recognized in the current period they are determined and reflect the inception-to-date effect of such changes. Segment operating profit and margin may also be impacted favorably or unfavorably by other items, which may or may not impact sales. Favorable items may include the positive resolution of contractual matters, cost recoveries on severance and restructuring, insurance recoveries and gains on sales of assets. Unfavorable items may include the adverse resolution of contractual matters; supply chain disruptions; restructuring charges (except for significant severance actions, which are excluded from segment operating results); reserves for disputes; certain asset impairments; and losses on sales of certain assets. Our consolidated net profit booking rate adjustments increased net sales by $1.6 billion in 2023, $2.0 billion in 2022, and $2.2 billion in 2021. These adjustments increased segment operating profit by approximately $1.6 billion ($1.3 billion, or $4.98 per share, after-tax) in 2023, $1.8 billion ($1.4 billion, or $5.40 per share, after-tax) in 2022 and $2.0 billion ($1.6 billion, or $5.81 per share, after-tax) in 2021. We have various development programs for new and upgraded products, services, and related technologies which have complex design and technical challenges. This development work is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work by us and our suppliers. Many of these programs have cost-type contracting arrangements (e.g. cost-reimbursable or cost-plus-fee). In such cases, the associated financial risks are primarily in reduced fees, lower profit rates, or program cancellation if cost, schedule, or technical performance issues arise. However, some of our existing development programs are contracted on a fixed-price basis or include cost-type contracting for the development phase with fixed-price production options and our customers are increasingly implementing procurement policies such as these that shift risk to contractors. Competitively bid programs with fixed-price development work or fixed-price production options increase the risk of a reach-forward loss upon contract award and during the period of contract performance. Due to the complex and often experimental nature of development programs, we may experience (and have experienced in the past) technical and quality issues during the development of new products or technologies for a variety of reasons. Our development programs are ongoing, and while we believe the cost and fee estimates incorporated in the financial statements are appropriate, the technical complexity of these programs and fixed-price contract structure creates financial risk as estimated completion costs may exceed the current contract value, which could trigger earnings charges, termination provisions, or other financially significant exposures. These programs have risk for reach-forward losses if our estimated costs exceed our estimated contract revenues, and such losses could be significant to our financial results, cash flows, or financial condition. Any such losses are recorded in the period in which the loss is evident. We have experienced performance issues on a classified fixed-price incentive fee contract that involves highly complex design and systems integration at our Aeronautics business segment and have periodically recognized reach-forward losses. As of December 31, 2023, cumulative losses remained at approximately $270 million. We will continue to monitor the technical requirements and our performance, the remaining work and any future changes in scope or schedule, and estimated costs to complete the program and may have to record additional losses in future periods if we experience further performance issues, increases in scope, or cost growth, which could be material to our financial results. In addition, we and our industry team will continue to incur advanced procurement costs (also referred to as pre-contract costs) in order to enhance our ability to achieve the schedule and certain milestones. We will monitor the recoverability of pre-contract costs, which could be impacted by the customer’s decision regarding future phases of the program. We are responsible for a program to design, develop and construct a ground-based radar at our RMS business segment. The program has experienced performance issues for which we have periodically recognized reach-forward losses. As of December 31, 2023, cumulative losses remained at approximately $280 million. We will continue to monitor our performance, any future changes in scope, and estimated costs to complete the program and may have to record additional losses in future periods if we experience further performance issues, increases in scope, or cost growth. However, based on the losses previously recorded, the near completion status of the program, and our current estimate of the sales and costs to complete the program, at this time we do not anticipate that additional losses, if any, would be material to our financial results or financial condition. We have contracted with the Canadian Government for the Canadian Maritime Helicopter Program (CMHP) at our RMS business segment that provides for design, development, and production of CH-148 aircraft (the Original Equipment contract), which is a military variant of the S-92 helicopter, and for logistical support to the fleet (the In Service Support contract) over an extended time period. We are currently in discussions with the Canadian Government to potentially restructure certain contractual terms and conditions that may be beneficial to both parties. The program has experienced performance issues, including delays in the final aircraft deliveries from the original contract requirement, and the Royal Canadian Air Force’s flight hours have been less than originally anticipated, which has impacted program revenues and the recovery of our costs under this program. We have incurred significant costs and recognized the related sales, a portion of which are currently included in contract assets on the balance sheet. Such assets are recovered based on flight hours. Future sales and recovery of costs under the program are highly dependent upon achieving a certain number of flight hours, which are uncertain and dependent on aircraft availability and performance, and the availability of Canadian government resources. During the second quarter of 2023, due to increases in estimated costs for the production and lower than planned revenues for the logistical support program considering discussions with the customer and subsequent analysis, we recognized a loss of $100 million ($75 million, or $0.29 per share, after-tax) on the program. Future performance issues, lower than forecast flight hours, or changes in our estimates due to the outcome of any restructuring discussions, including revised contract scope or customer requirements may further affect our ability to recover our costs, including the contract assets recognized on the balance sheet, or our assessment of the likelihood of cost recovery and may result in additional losses that could be material to our operating results. As of December 31, 2023, cumulative losses remained unchanged. We also have a number of contracts with Türkish industry for the Türkish Utility Helicopter Program (TUHP), which anticipates co-production with Türkish industry for production of T70 helicopters for use in Türkiye, as well as the related provision of Türkish goods and services under buy-back or offset obligations, to include the future sales of helicopters built in Türkiye for sale globally. In 2020, the U.S. Government imposed certain sanctions on Türkish entities and persons that have affected our ability to perform under the TUHP contracts and we have provided force majeure notices under the affected contracts. As of December 31, 2023, we have recorded insignificant losses related to development work for the program. The TUHP contracts may be negotiated to be restructured or terminated, either in whole or in part and as a result, we could be at risk of recording significant reach-forward losses in future periods. Additionally, we could elect to pursue other relief or remedies, which could result in a further reduction in sales, the imposition of penalties or assessment of damages, and increased unrecoverable costs, which could be material to our financial results. Our MFC business segment was previously awarded a competitively bid classified contract, which includes multiple phases of the program. We are currently performing on a phase which is primarily structured as cost-type. Additional phases are primarily fixed price and are not currently able to be awarded. If the additional phases are awarded at later dates, some of which could be within the next twelve months, we expect that those phases would be performed at a loss. As of December 31, 2023, cumulative losses recognized were approximately $45 million. We will continue to monitor the circumstances on the program and we may be required to recognize a reach-forward loss related to any additional phases at such time that we determine it is probable that they will be awarded. Any such losses could be material to our financial results. Research and development and similar costs – 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. Company-funded R&D costs are allocated to customer contracts as part of the general and administrative overhead costs and are generally recoverable to the extent allocable to our cost-reimbursable customer contracts with the U.S. Government. These costs also may be recoverable to the extent allocable to certain fixed-price incentive contracts with the U.S. Government. Customer-funded R&D costs are charged directly to the related customer contracts. Substantially all R&D costs are charged to cost of sales as incurred. Company-funded R&D costs charged to cost of sales totaled $1.5 billion, $1.7 billion and $1.5 billion in 2023, 2022 and 2021. Stock-based compensation – We issue stock-based compensation awards in the form of restricted stock units (RSUs) and performance stock units (PSUs) that generally vest three years from the grant date and are settled in shares. Compensation cost related to all stock-based awards is measured at the grant date based on the estimated fair value of the award. The grant date fair value of RSUs is equal to the closing market price of our common stock on the grant date less a discount to reflect the delay in payment of dividend-equivalent cash payments that are made only upon vesting. The grant date fair value of PSUs is measured in a manner similar to RSUs for awards that vest based on service and performance conditions or using a Monte Carlo model for awards that vest based on service and market conditions. For all RSUs, we recognize the grant date fair value, less estimated forfeitures, as compensation expense ratably over the requisite service period, which is shorter than the vesting period if the employee is retirement eligible on the date of grant or will become retirement eligible before the end of the vesting period. For PSUs that vest based on service and performance conditions, we recognize the grant date fair value, less estimated forfeitures, as compensation expense ratably over the vesting period based on the number of awards expected to ultimately vest. For PSUs that vest based on service and market conditions, we recognize the grant date fair value, less estimated forfeitures, as compensation expense ratably over the vesting period. At each reporting date, estimated forfeitures for all stock-based compensation awards and the number of PSUs expected to vest based on service and performance conditions is adjusted. Income taxes – We calculate our provision for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized based on the future tax consequences attributable to temporary differences that exist between the financial statement carrying amount of assets and liabilities and their respective tax bases, as well as from operating loss and tax credit carry-forwards. The provision for income taxes differs from the amounts currently receivable or payable because certain items of income and expense are recognized in different periods for financial reporting purposes than for income tax purposes. We measure deferred tax assets and liabilities using enacted tax rates that will apply in the years in which we expect the temporary differences to be recovered or paid. We periodically assess our tax exposures related to periods that are open to examination. Based on the latest available information, we evaluate our tax positions to determine whether the position will more likely than not be sustained upon examination by the Internal Revenue Service (IRS) or other taxing authorities. If we cannot reach a more-likely-than-not determination, no benefit is recorded. If we determine that the tax position is more likely than not to be sustained, we record the largest amount of benefit that is more likely than not to be realized when the tax position is settled. We record interest and penalties related to income taxes as a component of income tax expense on our consolidated statements of earnings. In accordance with the regulations that govern cost accounting requirements for government contracts, current state and local income and franchise taxes are generally considered allowable and allocable costs and, consistent with industry practice, are recorded in operating costs and expenses. We generally recognize changes in deferred state taxes and unrecognized state tax benefits in unallocated corporate expenses. Cash and cash equivalents – Cash equivalents include highly liquid instruments with original maturities of 90 days or less. Receivables – Receivables, net represent our unconditional right to consideration under the contract and include amounts billed and currently due from customers. Receivables, net are recorded at the net amount expected to be collected. There were no significant impairment losses related to our receivables in 2023, 2022 or 2021. Contract assets – Contract assets include unbilled amounts typically resulting from sales under contracts when the percentage-of-completion cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. Contract assets are recorded at the net amount expected to be billed and collected. Contract assets are classified as current based on our contract operating cycle, and include amounts that may be billed and collected beyond one year due to the long-cycle nature of our contracts. Contract liabilities – Contract liabilities include advance payments and billings in excess of revenue recognized. Contract liabilities are classified as current based on our contract operating cycle and reported on a contract-by-contract basis, net of revenue recognized, at the end of each reporting period. Inventories – We record inventories at the lower of cost or estimated net realizable value. The majority of our inventory represents work-in-process for contracts where control has not yet passed to the customer. Work-in-process primarily consists of labor, material, subcontractor, and overhead costs. In addition, costs incurred to fulfill a contract in advance of the contract being awarded are recorded in inventories as work-in-process if we determine that those costs relate directly to a contract or to an anticipated contract that we can specifically identify and contract award is probable, the costs generate or enhance resources that will be used in satisfying performance obligations, and the costs are recoverable (referred to as pre-contract costs). Pre-contract costs that are initially capitalized in inventory are generally recognized as cost of sales consistent with the transfer of products and services to the customer upon the receipt of the anticipated contract. All other pre-contract costs, including start-up costs, are expensed as incurred. We determine the costs of other inventories such as materials, spares and supplies by using the first-in first-out or average cost methods. If events or changes in circumstances indicate that pre-contract costs are no longer recoverable or the utility of our inventories have diminished through damage, deterioration, obsolescence, changes in price or other causes, a loss is recognized in the period in which it occurs. Property, plant and equipment – Property, plant and equipment are initially recorded at cost. The cost of plant and equipment are depreciated generally using accelerated methods during the first half of the estimated useful lives of the assets and the straight-line method thereafter. The estimated useful lives of our plant and equipment generally range from 10 to 40 years for buildings and five to 15 years for machinery and equipment. No depreciation expense is recorded on construction in progress until such assets are placed into operation. We review the carrying amounts of long-lived assets for impairment if events or changes in the facts and circumstances indicate that their carrying amounts may not be recoverable. We assess impairment by comparing the estimated undiscounted future cash flows of the related asset grouping to its carrying amount. If an asset is determined to be impaired, we recognize an impairment charge in the current period for the difference between the fair value of the asset and its carrying amount. Capitalized software – We capitalize certain costs associated with the development or purchase of internal-use software. The amounts capitalized are included in other noncurrent assets on our consolidated balance sheets and are amortized on a straight-line basis over the estimated useful life of the resulting software, which ranges from two to 15 years. As of December 31, 2023 and 2022, capitalized software totaled $1.4 billion and $919 million, net of accumulated amortization of $2.8 billion and $2.6 billion. No amortization expense is recorded until the software is ready for its intended use. Amortization expense related to capitalized software was $263 million in 2023, $253 million in 2022 and $175 million in 2021. Fair value of financial instruments – We measure the fair value of our financial instruments using observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. The following hierarchy classifies the inputs used to determine fair value into three levels: Level 1 – quoted prices in active markets for identical assets or liabilities. Level 2 – inputs, other than quoted prices, observable by a marketplace participant either directly or indirectly. Level 3 – unobservable inputs significant to the fair value measurement. Investments – We hold a portfolio of marketable securities to fund our non-qualified employee benefit plans. A portion of these securities are held in common/collective trust funds and are measured at fair value using Net Asset Value (NAV) per share as a practical expedient. Marketable securities accounted for as trading are recorded at fair value on a recurring basis and are included in other noncurrent assets on our consolidated balance sheets. Gains and losses on these investments are included in other unallocated, net within cost of sales on our consolidated statements of earnings. We make investments in companies that we believe are advancing or developing new technologies applicable to our business. These investments are primarily in early-stage companies and may be in the form of common or preferred stock, warrants, convertible debt securities, investments in funds or equity method investments. Most of these investments are in equity securities without readily determinable fair values (privately held securities), which are measured initially at cost and are then adjusted to fair value only if there is an observable price change or reduced for impairment, if applicable. The carrying amounts of the investments were $581 million and $589 million at December 31, 2023 and December 31, 2022 and are included on our consolidated balance sheets within other assets, both current and noncurrent. Changes in fair value and/or sales of investments are reflected in the other non-operating income, net account on our consolidated statements of earnings. During 2023 and 2022, we recorded net losses of $64 million ($48 million, or $0.19 per share, after-tax) and $114 million ($86 million, or $0.33 per share, after-tax). During 2021, we recorded net gains of $265 million ($199 million, or $0.72 per share, after-tax). Equity method investments – Investments where we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in other noncurrent assets on our consolidated balance sheets. Significant influence typically exists if we have a 20% to 50% ownership interest in the investee. Under this method of accounting, our share of the net earnings or losses of the investee is included in operating profit in other income, net on our consolidated statements of earnings since the activities of the investee are closely aligned with the operations of the business segment holding the investment. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period. As of December 31, 2023 and December 31, 2022, our equity method investments totaled $701 million and $685 million, which was primarily composed of our investment in the United Launch Alliance (ULA) joint venture. Our share of net earnings related to our equity method investees was $40 million in 2023, $114 million in 2022 and $97 million in 2021, of which approximately $20 million, $100 million and $65 million was included in our Space business segment operating profit. Goodwill and Intangible Assets – We perform an impairment test of our goodwill at least annually in the fourth quarter or more frequently whenever events or changes in circumstances indicate the carrying value of goodwill may be impaired. We may use both a qualitative and quantitative approaches when testing goodwill for impairment. For selected reporting units where we use the qualitative approach, we perform a qualitative evaluation of events and circumstances impacting the reporting unit to determine the likelihood of goodwill impairment. Based on that qualitative evaluation, if we determine it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary. Otherwise we perform a quantitative impairment test. We perform quantitative tests for most reporting units at least once every three years. However, for certain reporting units we may perform a quantitative impairment test every year. To perform the quantitative impairment test we compare the fair value of a reporting unit to its carrying value, including goodwill. If the fair value of a reporting unit exceeds its carrying value, goodwill of the reporting unit is not impaired. If the carrying value of the reporting unit, including goodwill, exceeds its fair value, a goodwill impairment loss is recognized in an amount equal to that excess. We generally estimate the fair value of each reporting unit using a combination of a discounted cash flow (DCF) analysis and market-based valuation methodologies such as comparable public company trading values and values observed in recent business acquisitions. Finite-lived intangibles are amortized to expense over their applicable useful lives, ranging from three to 20 years, based on the nature of the asset and the underlying pattern of economic benefit as reflected by future net cash inflows. Acquired intangible assets deemed to have indefinite lives are not amortized, but are subject to annual impairment testing or more frequently if events or change in circumstance indicate that it is more likely than not that the asset is impaired. We perform an impairment test of finite-lived intangibles whenever events or changes in circumstances indicate their carrying value may be impaired. Leases – We evaluate whether our contractual arrangements contain leases at the inception of such arrangements. Specifically, we consider whether we can control the underlying asset and have the right to obtain substantially all of the economic benefits or outputs from the asset. Substantially all of our leases are long-term operating leases with fixed payment terms. We do not have significant financing leases. Our right-of-use (ROU) operating lease assets represent our right to use an underlying asset for the lease term, and our operating lease liabilities represent our obligation to make lease payments. ROU operating lease assets are recorded in other noncurrent assets in our consolidated balance sheet. Operating lease liabilities are recorded in other current liabilities or other noncurrent liabilities in our consolidated balance sheet based on their contractual due dates. Both the ROU operating lease asset and liability are recognized as of the lease commencement date at the present value of the lease payments over the lease term. Most of our leases do not provide an implicit rate that can readily be determined. Therefore, we use a discount rate based on our incremental borrowing rate, which is determined using our credit rating and information available as of the commencement date. ROU operating lease assets include lease payments made at or before the lease commencement date, net of any lease incentives. Our operating lease agreements may include options to extend the lease term or terminate it early. We include options to extend or terminate leases in the ROU operating lease asset and liability when it is reasonably certain we will exercise these options. Operating lease expense is recognized on a straight-line basis over the lease term and is included in cost of sales on our consolidated statement of earnings. We have operating lease arrangements with lease and non-lease components. The non-lease components in our arrangements are not significant when compared to the lease components. For all operating leases, we account for the lease and non-lease components as a single component. Additionally, for certain equipment leases, we apply a portfolio approach to recognize operating lease ROU assets and liabilities. We evaluate ROU assets for impairment consistent with our property, plant and equipment policy. Postretirement benefit plans – Many of our employees and retirees participate in defined benefit pension plans, retiree medical and life insurance plans, and other postemployment plans (collectively, postretirement benefit plans). Obligation amounts we record related to our postretirement benefit plans are computed based on service to date, using actuarial valuations that are based in part on certain key economic assumptions we make, including the discount rate, the expected long-term rate of return on plan assets and other actuarial assumptions including participant longevity (also known as mortality) and health care cost trend rates, each as appropriate based on the nature of the plans. A market-related value of our plan assets, determined using actual asset gains or losses over the prior three year period, is used to calculate the amount of deferred asset gains or losses to be amortized. These asset gains or losses, along with those resulting from adjustments to our benefit obligation, will be amortized to expense using the corridor method, where gains and losses are recognized over a period of years to the extent they exceed 10% of the greater of plan assets or benefit obligations. We recognize on a plan-by-plan basis the funded status of our postretirement benefit plans as either an asset recorded within other noncurrent assets or a liability recorded within noncurrent liabilities on our consolidated balance sheets. The GAAP funded status is measured as the difference between the fair value of the plan’s assets and the benefit obligation of the plan. The funded status under the Employee Retirement Income Security Act of 1974 (ERISA), as amended, is calculated on a different basis than under GAAP. Postemployment plans – We record a liability for postemployment benefits, such as severance or job training, typically when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. Environmental matters – We record a liability for environmental matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of liability recorded is based on our estimate of the costs to be incurred for remediation at a particular site. We do not discount the recorded liabilities, as the amount and timing of future cash payments are not fixed or cannot be reliably determined. Our environmental liabilities are recorded on our consolidated balance sheets within other liabilities, both current and noncurrent. We expect to include a substantial portion of environmental costs in our net sales and cost of sales in future periods pursuant to U.S. Government regulation. At the time a liability is recorded for future environmental costs, we record assets for estimated future recovery considered probable through the pricing of products and services to agencies of the U.S. Government, regardless of the contract form (e.g., cost-reimbursable, fixed-price). We continually evaluate the recoverability of our assets for the portion of environmental costs that are probable of future recovery by assessing, among other factors, U.S. Government regulations, our U.S. Government business base and contract mix, our history of receiving reimbursement of such costs, and efforts by some U.S. Government representatives to limit such reimbursement. We include the portions of those environmental costs expected to be allocated to our non-U.S. government contracts, or determined not to be recoverable under U.S. Government contracts, in our cost of sales at the time the liability is established or adjusted. Our assets for the portion of environmental costs that are probable of future recovery are recorded on our consolidated balance sheets within other assets, both current and noncurrent. We project costs and recovery of costs over approximately 20 years. Derivative financial instruments – Derivatives are recorded at their fair value and included in other current and noncurrent assets and liabilities on our consolidated balance sheets. The classification of gains and losses resulting from changes in the fair values of derivatives is dependent on our intended use of the derivative and its resulting designation. Adjustments to reflect changes in fair values of derivatives attributable to highly effective hedges are either reflected in earnings and largely offset by corresponding adjustments to the hedged items or reflected net of income taxes in accumulated other comprehensive loss until the hedged transaction is recognized in earnings. Changes in the fair value of the derivatives that are not highly effective, if any, are immediately recognized in earnings. Recent Accounting Pronouncements Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (CODM). The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition. Income Taxes (Topic 740): Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid. ASU No. 2023-09 requires a public business entity (PBE) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments in this ASU prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures for all period presented. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows, and financial condition.

Organization – We are a global security and aerospace company principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. We also provide a broad range of management, engineering, technical, scientific, logistics, system integration and cybersecurity services. We serve both U.S. and international customers with products and services that have defense, civil and commercial applications, with our principal customers being agencies of the U.S. Government. As described in “Note 3 – Information on Business Segments”, we operate in four business segments: Aeronautics, MFC, RMS and Space.

Basis of presentation – These consolidated financial statements include the accounts of subsidiaries we control and variable interest entities if we are the primary beneficiary. We eliminate intercompany balances and transactions in consolidation. We classify certain assets and liabilities as current utilizing the duration of the related contract or program as our operating cycle, which is generally longer than one year. This primarily impacts receivables, contract assets, inventories, and contract liabilities. We classify all other assets and liabilities based on whether the asset will be realized or the liability will be paid within one year.

Effective January 1, 2023, we no longer consider amortization expense related to purchased intangible assets when evaluating the operating performance of our business segments. As a result, intangible asset amortization expense, which was previously included in segment operating profit, is now reported in unallocated corporate expense within total consolidated operating profit. This change has no impact on our consolidated operating results. Management believes this updated presentation better aligns with how the business is viewed and managed and will provide better insights into business segment performance. This change has been applied to the amounts in this Form 10-K, including amounts for 2022 and 2021. See “Note 3 – Information on Business Segments” for further information regarding the impact of this change on our current and prior period segment operating profit.

Use of estimates – We prepare our consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP). In doing so, we are required to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base these estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates. Significant estimates inherent in the preparation of our consolidated financial statements include, but are not limited to, accounting for sales and cost recognition; postretirement benefit plans; environmental liabilities and assets for the portion of environmental costs that are probable of future recovery; evaluation of goodwill, intangible assets, investments and other assets for impairment; income taxes including deferred income taxes; fair value measurements; and contingencies.

Revenue Recognition – The majority of our net sales are generated from long-term contracts with the U.S. Government and international customers (including foreign military sales (FMS) contracted through the U.S. Government) for the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. For certain contracts that meet the foregoing requirements, primarily international direct commercial sale contracts, we are required to obtain certain regulatory approvals. In these cases, we recognize revenue when it is probable that we will receive regulatory approvals based upon all known facts and circumstances. We provide our products and services under fixed-price and cost-reimbursable contracts.

Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract plus a fee up to a ceiling based on the amount that has been funded. Typically, we enter into three types of cost-reimbursable contracts: cost-plus-award-fee, cost-plus-incentive-fee, and cost-plus-fixed-fee. Cost-plus-award-fee contracts provide for an award fee that varies within specified limits based on the customer’s assessment of our performance against a predetermined set of criteria, such as targets based on cost, quality, technical and schedule criteria. Cost-plus-incentive-fee contracts provide for

We evaluate the products or services promised in each contract at inception to determine whether the contract should be accounted for as having one or more performance obligations. The products and services in our contracts are typically not distinct from one another due to their complex relationships and the significant contract management functions required to perform under the contract. Accordingly, our contracts are typically accounted for as one performance obligation. In limited cases, our contracts have more than one distinct performance obligation, which occurs when we perform activities that are not highly complex or interrelated or involve different product lifecycles. Significant judgment is required in determining performance obligations, and these decisions could change the amount of revenue and profit recorded in a given period. We classify net sales as products or services on our consolidated statements of earnings based on the predominant attributes of the performance obligations.

We determine the transaction price for each contract based on the consideration we expect to receive for the products or services being provided under the contract. For contracts where a portion of the price may vary (e.g. awards, incentive fees and claims), we estimate variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. We analyze the risk of a significant revenue reversal and if necessary constrain the amount of variable consideration recognized in order to mitigate this risk.

At the inception of a contract we estimate the transaction price based on our current rights and do not contemplate future modifications (including unexercised options) or follow-on contracts until they become legally enforceable. Contracts are often subsequently modified to include changes in specifications, requirements or price, which may create new or change existing enforceable rights and obligations. Depending on the nature of the modification, we consider whether to account for the modification as an adjustment to the existing contract or as a separate contract. Generally, modifications to our contracts are not distinct from the existing contract due to the significant integration and interrelated tasks provided in the context of the contract. Therefore, such modifications are accounted for as if they were part of the existing contract and recognized as a cumulative adjustment to revenue.

For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation based on the estimated standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount we would sell the product or service to a customer on a standalone basis (i.e., not bundled with any other products or services). Our contracts with the U.S. Government, including FMS contracts, are subject to the Federal Acquisition Regulations (FAR) and the price is typically based on estimated or actual costs plus a reasonable profit margin. As a result of these regulations, the standalone selling price of products or services in our contracts with the U.S. Government and FMS contracts are typically equal to the selling price stated in the contract.

For non-U.S. government contracts with multiple performance obligations, we evaluate whether the stated selling prices for the products or services represent their standalone selling prices. We primarily sell customized solutions unique to a customer’s specifications. When it is necessary to allocate the transaction price to multiple performance obligations, we typically use the expected cost plus a reasonable profit margin to estimate the standalone selling price of each product or service. We occasionally sell standard products or services with observable standalone sales transactions. In these situations, the observable standalone sales transactions are used to determine the standalone selling price.

We recognize revenue as performance obligations are satisfied and the customer obtains control of the products and services. In determining when performance obligations are satisfied, we consider factors such as contract terms, payment terms and whether there is an alternative future use of the product or service. Substantially all of our revenue is recognized over time as we perform under the contract because control of the work in process transfers continuously to the customer. For most contracts with the U.S. Government and FMS contracts, this continuous transfer of control of the work in process to the customer is supported by clauses in the contract that give the customer ownership of work in process and allow the customer to unilaterally terminate the contract for convenience and pay us for costs incurred plus a reasonable profit. For most non-U.S. government contracts, primarily international direct commercial contracts, continuous transfer of control to our customer is supported because we deliver products that do not have an alternative use to us and if our customer were to terminate the

For performance obligations to deliver products with continuous transfer of control to the customer, revenue is recognized based on the extent of progress towards completion of the performance obligation, generally using the percentage-of-completion cost-to-cost measure of progress for our contracts because it best depicts the transfer of control to the customer as we incur costs on our contracts. Under the percentage-of-completion cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs to complete the performance obligation(s). For performance obligations to provide services to the customer, revenue is recognized over time based on costs incurred or the right to invoice method (in situations where the value transferred matches our billing rights) as our customer receives and consumes the benefits.

For performance obligations in which control does not continuously transfer to the customer, we recognize revenue at the point in time in which each performance obligation is fully satisfied. This coincides with the point in time the customer obtains control of the product or service, which typically occurs upon customer acceptance or receipt of the product or service, given that we maintain control of the product or service until that point.

Backlog (i.e., unfulfilled or remaining performance obligations) represents the sales we expect to recognize for our products and services for which control has not yet transferred to the customer. It is converted into sales in future periods as work is performed or deliveries are made. For our cost-reimbursable and fixed-priced-incentive contracts, the estimated consideration we expect to receive pursuant to the terms of the contract may exceed the contractual award amount. The estimated consideration is determined at the outset of the contract and is continuously reviewed throughout the contract period. In determining the estimated consideration, we consider the risks related to the technical, schedule and cost impacts to complete the contract and an estimate of any variable consideration. Periodically, we review these risks and may increase or decrease backlog accordingly. As the risks on such contracts are successfully retired, the estimated consideration from customers may be reduced, resulting in a reduction of backlog without a corresponding recognition of sales. As of December 31, 2023, our ending backlog was $160.6 billion. We expect to recognize approximately 36% of our backlog over the next 12 months and approximately 62% over the next 24 months as revenue, with the remainder recognized thereafter.

For arrangements with the U.S. Government and FMS contracts, we generally do not begin work on contracts until funding is appropriated by the customer. Billing timetables and payment terms on our contracts vary based on a number of factors, including the contract type. Typical payment terms under fixed-price contracts with the U.S. Government provide that the customer pays either performance-based payments (PBPs) based on the achievement of contract milestones or progress payments based on a percentage of costs we incur. Typical payment terms under cost-reimbursable contracts with the U.S Government provide for billing of allowable costs incurred plus applicable fee on a monthly or semi-monthly basis. For the majority of our international direct commercial contracts to deliver complex systems, we typically receive advance payments prior to commencement of work, as well as milestone payments that are paid in accordance with the terms of our contract as we perform. We recognize a liability for payments in excess of revenue recognized, which is presented as a contract liability on the balance sheet. The portion of payments retained by the customer until final contract settlement is not considered a significant financing component because the intent is to protect the customer from our failure to adequately complete some or all of the obligations under the contract. Payments received from customers in advance of revenue recognition are not considered to be significant financing components because they are used to meet working capital demands that can be higher in the early stages of a contract.

Significant estimates and assumptions are made in estimating contract sales, costs, and profit. We estimate profit as the difference between estimated revenues and total estimated costs to complete the contract. At the outset of a long-term contract, we identify and monitor risks to the achievement of the technical, schedule and cost aspects of the contract, as well as our ability to earn variable consideration, and assess the effects of those risks on our estimates of sales and total costs to complete the contract. The estimates consider the technical requirements (e.g., a newly-developed product versus a mature product), the schedule and associated tasks (e.g., the number and type of milestone events) and costs (e.g., material, labor, subcontractor, overhead, general and administrative and the estimated costs to fulfill our industrial cooperation agreements, sometimes referred to as offset or localization agreements, required under certain contracts with international customers). The initial profit booking rate of each contract considers risks surrounding the ability to achieve the technical requirements, schedule and costs in the initial estimated total costs to complete the contract. Profit booking rates may increase during the performance of the contract if we successfully retire risks related to technical, schedule and cost aspects of the contract, which decreases the estimated total costs to complete the contract or may increase the variable consideration we expect to receive on the contract.

Conversely, our profit booking rates may decrease if the estimated total costs to complete the contract increase or our estimates of variable consideration we expect to receive decrease. All of the estimates are subject to change during the performance of the contract and may affect the profit booking rate. When estimates of total costs to be incurred on a contract exceed total estimates of the transaction price, a provision for the entire loss is determined at the contract level and is recorded in the period in which the loss is evident, which we refer to as a reach-forward loss.

Comparability of our segment sales, operating profit and operating margin may be impacted favorably or unfavorably by changes in profit booking rates on our contracts. Increases in the profit booking rates, typically referred to as favorable profit adjustments, usually relate to revisions in the estimated total costs to fulfill the performance obligations that reflect improved conditions on a particular contract. Conversely, conditions on a particular contract may deteriorate, resulting in an increase in the estimated total costs to fulfill the performance obligations and a reduction in the profit booking rate and are typically referred to as unfavorable profit adjustments. Increases or decreases in profit booking rates are recognized in the current period they are determined and reflect the inception-to-date effect of such changes. Segment operating profit and margin may also be impacted favorably or unfavorably by other items, which may or may not impact sales. Favorable items may include the positive resolution of contractual matters, cost recoveries on severance and restructuring, insurance recoveries and gains on sales of assets. Unfavorable items may include the adverse resolution of contractual matters; supply chain disruptions; restructuring charges (except for significant severance actions, which are excluded from segment operating results); reserves for disputes; certain asset impairments; and losses on sales of certain assets.

We have various development programs for new and upgraded products, services, and related technologies which have complex design and technical challenges. This development work is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work by us and our suppliers. Many of these programs have cost-type contracting arrangements (e.g. cost-reimbursable or cost-plus-fee). In such cases, the associated financial risks are primarily in reduced fees, lower profit rates, or program cancellation if cost, schedule, or technical performance issues arise.

However, some of our existing development programs are contracted on a fixed-price basis or include cost-type contracting for the development phase with fixed-price production options and our customers are increasingly implementing procurement policies such as these that shift risk to contractors. Competitively bid programs with fixed-price development work or fixed-price production options increase the risk of a reach-forward loss upon contract award and during the period of contract performance. Due to the complex and often experimental nature of development programs, we may experience (and have experienced in the past) technical and quality issues during the development of new products or technologies for a variety of reasons. Our development programs are ongoing, and while we believe the cost and fee estimates incorporated in the financial statements are appropriate, the technical complexity of these programs and fixed-price contract structure creates financial risk as estimated completion costs may exceed the current contract value, which could trigger earnings charges, termination provisions, or other financially significant exposures. These programs have risk for reach-forward losses if our estimated costs exceed our estimated contract revenues, and such losses could be significant to our financial results, cash flows, or financial condition. Any such losses are recorded in the period in which the loss is evident.

We have experienced performance issues on a classified fixed-price incentive fee contract that involves highly complex design and systems integration at our Aeronautics business segment and have periodically recognized reach-forward losses. As of December 31, 2023, cumulative losses remained at approximately $270 million. We will continue to monitor the technical requirements and our performance, the remaining work and any future changes in scope or schedule, and estimated costs to complete the program and may have to record additional losses in future periods if we experience further performance issues, increases in scope, or cost growth, which could be material to our financial results. In addition, we and our industry team will continue to incur advanced procurement costs (also referred to as pre-contract costs) in order to enhance our ability to achieve the schedule and certain milestones. We will monitor the recoverability of pre-contract costs, which could be impacted by the customer’s decision regarding future phases of the program.

We are responsible for a program to design, develop and construct a ground-based radar at our RMS business segment. The program has experienced performance issues for which we have periodically recognized reach-forward losses. As of December 31, 2023, cumulative losses remained at approximately $280 million. We will continue to monitor our performance, any future changes in scope, and estimated costs to complete the program and may have to record additional losses in future periods if we experience further performance issues, increases in scope, or cost growth. However, based on the losses previously recorded, the near completion status of the program, and our current estimate of the sales and costs to complete the

We have contracted with the Canadian Government for the Canadian Maritime Helicopter Program (CMHP) at our RMS business segment that provides for design, development, and production of CH-148 aircraft (the Original Equipment contract), which is a military variant of the S-92 helicopter, and for logistical support to the fleet (the In Service Support contract) over an extended time period. We are currently in discussions with the Canadian Government to potentially restructure certain contractual terms and conditions that may be beneficial to both parties. The program has experienced performance issues, including delays in the final aircraft deliveries from the original contract requirement, and the Royal Canadian Air Force’s flight hours have been less than originally anticipated, which has impacted program revenues and the recovery of our costs under this program. We have incurred significant costs and recognized the related sales, a portion of which are currently included in contract assets on the balance sheet. Such assets are recovered based on flight hours. Future sales and recovery of costs under the program are highly dependent upon achieving a certain number of flight hours, which are uncertain and dependent on aircraft availability and performance, and the availability of Canadian government resources. During the second quarter of 2023, due to increases in estimated costs for the production and lower than planned revenues for the logistical support program considering discussions with the customer and subsequent analysis, we recognized a loss of $100 million ($75 million, or $0.29 per share, after-tax) on the program. Future performance issues, lower than forecast flight hours, or changes in our estimates due to the outcome of any restructuring discussions, including revised contract scope or customer requirements may further affect our ability to recover our costs, including the contract assets recognized on the balance sheet, or our assessment of the likelihood of cost recovery and may result in additional losses that could be material to our operating results. As of December 31, 2023, cumulative losses remained unchanged.

We also have a number of contracts with Türkish industry for the Türkish Utility Helicopter Program (TUHP), which anticipates co-production with Türkish industry for production of T70 helicopters for use in Türkiye, as well as the related provision of Türkish goods and services under buy-back or offset obligations, to include the future sales of helicopters built in Türkiye for sale globally. In 2020, the U.S. Government imposed certain sanctions on Türkish entities and persons that have affected our ability to perform under the TUHP contracts and we have provided force majeure notices under the affected contracts. As of December 31, 2023, we have recorded insignificant losses related to development work for the program. The TUHP contracts may be negotiated to be restructured or terminated, either in whole or in part and as a result, we could be at risk of recording significant reach-forward losses in future periods. Additionally, we could elect to pursue other relief or remedies, which could result in a further reduction in sales, the imposition of penalties or assessment of damages, and increased unrecoverable costs, which could be material to our financial results.

Our MFC business segment was previously awarded a competitively bid classified contract, which includes multiple phases of the program. We are currently performing on a phase which is primarily structured as cost-type. Additional phases are primarily fixed price and are not currently able to be awarded. If the additional phases are awarded at later dates, some of which could be within the next twelve months, we expect that those phases would be performed at a loss. As of December 31, 2023, cumulative losses recognized were approximately $45 million. We will continue to monitor the circumstances on the program and we may be required to recognize a reach-forward loss related to any additional phases at such time that we determine it is probable that they will be awarded. Any such losses could be material to our financial results.

Research and development and similar costs – 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. Company-funded R&D costs are allocated to customer contracts as part of the general and administrative overhead costs and are generally recoverable to the extent allocable to our cost-reimbursable customer contracts with the U.S. Government. These costs also may be recoverable to the extent allocable to certain fixed-price incentive contracts with the U.S. Government. Customer-funded R&D costs are charged directly to the related customer contracts. Substantially all R&D costs are charged to cost of sales as incurred. Company-funded R&D costs charged to cost of sales totaled $1.5 billion, $1.7 billion and $1.5 billion in 2023, 2022 and 2021.

Stock-based compensation – We issue stock-based compensation awards in the form of restricted stock units (RSUs) and performance stock units (PSUs) that generally vest three years from the grant date and are settled in shares. Compensation cost related to all stock-based awards is measured at the grant date based on the estimated fair value of the award. The grant date fair value of RSUs is equal to the closing market price of our common stock on the grant date less a discount to reflect the delay in payment of dividend-equivalent cash payments that are made only upon vesting. The grant date fair value of PSUs is measured in a manner similar to RSUs for awards that vest based on service and performance conditions or using a Monte Carlo model for awards that vest based on service and market conditions.

For all RSUs, we recognize the grant date fair value, less estimated forfeitures, as compensation expense ratably over the requisite service period, which is shorter than the vesting period if the employee is retirement eligible on the date of grant or will become retirement eligible before the end of the vesting period. For PSUs that vest based on service and performance conditions, we recognize the grant date fair value, less estimated forfeitures, as compensation expense ratably over the vesting period based on the number of awards expected to ultimately vest. For PSUs that vest based on service and market conditions, we recognize the grant date fair value, less estimated forfeitures, as compensation expense ratably over the vesting period. At each reporting date, estimated forfeitures for all stock-based compensation awards and the number of PSUs expected to vest based on service and performance conditions is adjusted.

Income taxes – We calculate our provision for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized based on the future tax consequences attributable to temporary differences that exist between the financial statement carrying amount of assets and liabilities and their respective tax bases, as well as from operating loss and tax credit carry-forwards. The provision for income taxes differs from the amounts currently receivable or payable because certain items of income and expense are recognized in different periods for financial reporting purposes than for income tax purposes. We measure deferred tax assets and liabilities using enacted tax rates that will apply in the years in which we expect the temporary differences to be recovered or paid.

We periodically assess our tax exposures related to periods that are open to examination. Based on the latest available information, we evaluate our tax positions to determine whether the position will more likely than not be sustained upon examination by the Internal Revenue Service (IRS) or other taxing authorities. If we cannot reach a more-likely-than-not determination, no benefit is recorded. If we determine that the tax position is more likely than not to be sustained, we record the largest amount of benefit that is more likely than not to be realized when the tax position is settled. We record interest and penalties related to income taxes as a component of income tax expense on our consolidated statements of earnings.

Contract assets – Contract assets include unbilled amounts typically resulting from sales under contracts when the percentage-of-completion cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. Contract assets are recorded at the net amount expected to be billed and collected. Contract assets are classified as current based on our contract operating cycle, and include amounts that may be billed and collected beyond one year due to the long-cycle nature of our contracts.

Inventories – We record inventories at the lower of cost or estimated net realizable value. The majority of our inventory represents work-in-process for contracts where control has not yet passed to the customer. Work-in-process primarily consists of labor, material, subcontractor, and overhead costs. In addition, costs incurred to fulfill a contract in advance of the contract being awarded are recorded in inventories as work-in-process if we determine that those costs relate directly to a contract or to an anticipated contract that we can specifically identify and contract award is probable, the costs generate or enhance resources that will be used in satisfying performance obligations, and the costs are recoverable (referred to as pre-contract costs). Pre-contract costs that are initially capitalized in inventory are generally recognized as cost of sales consistent with the transfer of products and services to the customer upon the receipt of the anticipated contract. All other pre-contract costs, including start-up costs, are expensed as incurred. We determine the costs of other inventories such as materials, spares and supplies by using the first-in first-out or average cost methods. If events or changes in circumstances indicate that pre-contract costs are no longer recoverable or the utility of our inventories have diminished through damage, deterioration, obsolescence, changes in price or other causes, a loss is recognized in the period in which it occurs.

We review the carrying amounts of long-lived assets for impairment if events or changes in the facts and circumstances indicate that their carrying amounts may not be recoverable. We assess impairment by comparing the estimated undiscounted future cash flows of the related asset grouping to its carrying amount. If an asset is determined to be impaired, we recognize an impairment charge in the current period for the difference between the fair value of the asset and its carrying amount.

Capitalized software – We capitalize certain costs associated with the development or purchase of internal-use software. The amounts capitalized are included in other noncurrent assets on our consolidated balance sheets and are amortized on a straight-line basis over the estimated useful life of the resulting software, which ranges from two to 15 years. As of December 31, 2023 and 2022, capitalized software totaled $1.4 billion and $919 million, net of accumulated amortization of $2.8 billion and $2.6 billion. No amortization expense is recorded until the software is ready for its intended use. Amortization expense related to capitalized software was $263 million in 2023, $253 million in 2022 and $175 million in 2021.

Investments – We hold a portfolio of marketable securities to fund our non-qualified employee benefit plans. A portion of these securities are held in common/collective trust funds and are measured at fair value using Net Asset Value (NAV) per share as a practical expedient. Marketable securities accounted for as trading are recorded at fair value on a recurring basis and are included in other noncurrent assets on our consolidated balance sheets. Gains and losses on these investments are included in other unallocated, net within cost of sales on our consolidated statements of earnings.

We make investments in companies that we believe are advancing or developing new technologies applicable to our business. These investments are primarily in early-stage companies and may be in the form of common or preferred stock, warrants, convertible debt securities, investments in funds or equity method investments. Most of these investments are in equity securities without readily determinable fair values (privately held securities), which are measured initially at cost and are then adjusted to fair value only if there is an observable price change or reduced for impairment, if applicable. The carrying amounts of the investments were $581 million and $589 million at December 31, 2023 and December 31, 2022 and are included on our consolidated balance sheets within other assets, both current and noncurrent. Changes in fair value and/or sales of investments are reflected in the other non-operating income, net account on our consolidated statements of earnings. During 2023 and 2022, we recorded net losses of $64 million ($48 million, or $0.19 per share, after-tax) and $114 million ($86 million, or $0.33 per share, after-tax). During 2021, we recorded net gains of $265 million ($199 million, or $0.72 per share, after-tax).

Equity method investments – Investments where we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in other noncurrent assets on our consolidated balance sheets. Significant influence typically exists if we have a 20% to 50% ownership interest in the investee. Under this method of accounting, our share of the net earnings or losses of the investee is included in operating profit in other income, net on our consolidated statements of earnings since the activities of the investee are closely aligned with the operations of the business segment holding the investment. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period. As of December 31, 2023 and December 31, 2022, our equity method investments totaled $701 million and $685 million, which was primarily composed of our investment in the United Launch Alliance (ULA) joint venture. Our share of net earnings related to our equity method investees was $40 million in 2023, $114 million in 2022 and $97 million in 2021, of which approximately $20 million, $100 million and $65 million was included in our Space business segment operating profit.

Goodwill and Intangible Assets – We perform an impairment test of our goodwill at least annually in the fourth quarter or more frequently whenever events or changes in circumstances indicate the carrying value of goodwill may be impaired. We may use both a qualitative and quantitative approaches when testing goodwill for impairment. For selected reporting units where we use the qualitative approach, we perform a qualitative evaluation of events and circumstances impacting the reporting unit to determine the likelihood of goodwill impairment. Based on that qualitative evaluation, if we determine it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary. Otherwise we perform a quantitative impairment test. We perform quantitative tests for most reporting units at least once every three years. However, for certain reporting units we may perform a quantitative impairment test every year.

To perform the quantitative impairment test we compare the fair value of a reporting unit to its carrying value, including goodwill. If the fair value of a reporting unit exceeds its carrying value, goodwill of the reporting unit is not impaired. If the carrying value of the reporting unit, including goodwill, exceeds its fair value, a goodwill impairment loss is recognized in an amount equal to that excess. We generally estimate the fair value of each reporting unit using a combination of a discounted cash flow (DCF) analysis and market-based valuation methodologies such as comparable public company trading values and values observed in recent business acquisitions.

Finite-lived intangibles are amortized to expense over their applicable useful lives, ranging from three to 20 years, based on the nature of the asset and the underlying pattern of economic benefit as reflected by future net cash inflows. Acquired intangible assets deemed to have indefinite lives are not amortized, but are subject to annual impairment testing or more frequently if events or change in circumstance indicate that it is more likely than not that the asset is impaired. We perform an impairment test of finite-lived intangibles whenever events or changes in circumstances indicate their carrying value may be impaired.

Leases – We evaluate whether our contractual arrangements contain leases at the inception of such arrangements. Specifically, we consider whether we can control the underlying asset and have the right to obtain substantially all of the economic benefits or outputs from the asset. Substantially all of our leases are long-term operating leases with fixed payment terms. We do not have significant financing leases. Our right-of-use (ROU) operating lease assets represent our right to use an underlying asset for the lease term, and our operating lease liabilities represent our obligation to make lease payments. ROU operating lease assets are recorded in other noncurrent assets in our consolidated balance sheet. Operating lease liabilities are recorded in other current liabilities or other noncurrent liabilities in our consolidated balance sheet based on their contractual due dates.

Both the ROU operating lease asset and liability are recognized as of the lease commencement date at the present value of the lease payments over the lease term. Most of our leases do not provide an implicit rate that can readily be determined. Therefore, we use a discount rate based on our incremental borrowing rate, which is determined using our credit rating and information available as of the commencement date. ROU operating lease assets include lease payments made at or before the lease commencement date, net of any lease incentives.

We have operating lease arrangements with lease and non-lease components. The non-lease components in our arrangements are not significant when compared to the lease components. For all operating leases, we account for the lease and non-lease components as a single component. Additionally, for certain equipment leases, we apply a portfolio approach to recognize operating lease ROU assets and liabilities. We evaluate ROU assets for impairment consistent with our property, plant and equipment policy.

Postretirement benefit plans – Many of our employees and retirees participate in defined benefit pension plans, retiree medical and life insurance plans, and other postemployment plans (collectively, postretirement benefit plans). Obligation amounts we record related to our postretirement benefit plans are computed based on service to date, using actuarial valuations that are based in part on certain key economic assumptions we make, including the discount rate, the expected long-term rate of return on plan assets and other actuarial assumptions including participant longevity (also known as mortality) and health care cost trend rates, each as appropriate based on the nature of the plans.

A market-related value of our plan assets, determined using actual asset gains or losses over the prior three year period, is used to calculate the amount of deferred asset gains or losses to be amortized. These asset gains or losses, along with those resulting from adjustments to our benefit obligation, will be amortized to expense using the corridor method, where gains and losses are recognized over a period of years to the extent they exceed 10% of the greater of plan assets or benefit obligations.

We recognize on a plan-by-plan basis the funded status of our postretirement benefit plans as either an asset recorded within other noncurrent assets or a liability recorded within noncurrent liabilities on our consolidated balance sheets. The GAAP funded status is measured as the difference between the fair value of the plan’s assets and the benefit obligation of the plan. The funded status under the Employee Retirement Income Security Act of 1974 (ERISA), as amended, is calculated on a different basis than under GAAP.

Environmental matters – We record a liability for environmental matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of liability recorded is based on our estimate of the costs to be incurred for remediation at a particular site. We do not discount the recorded liabilities, as the amount and timing of future cash payments are not fixed or cannot be reliably determined. Our environmental liabilities are recorded on our consolidated balance sheets within other liabilities, both current and noncurrent. We expect to include a substantial portion of environmental costs in our net sales and cost of sales in future periods pursuant to U.S. Government regulation. At the time a liability is recorded for future environmental costs, we record assets for estimated future recovery considered probable through the pricing of products and services to agencies of the U.S. Government, regardless of the contract form (e.g., cost-reimbursable, fixed-price). We continually evaluate the recoverability of our assets for the portion of environmental costs that are probable of future recovery by assessing, among other factors, U.S. Government regulations, our U.S. Government business base and contract mix, our history of receiving reimbursement of such costs, and efforts by some U.S. Government representatives to limit such reimbursement. We include the portions of those environmental costs expected to be allocated to our non-U.S. government contracts, or determined not to be recoverable under U.S. Government contracts, in our cost of sales at the time the liability is established or adjusted. Our assets for the portion of environmental costs that are probable of future recovery are recorded on our consolidated balance sheets within other assets, both current and noncurrent. We project costs and recovery of costs over approximately 20 years.

Derivative financial instruments – Derivatives are recorded at their fair value and included in other current and noncurrent assets and liabilities on our consolidated balance sheets. The classification of gains and losses resulting from changes in the fair values of derivatives is dependent on our intended use of the derivative and its resulting designation. Adjustments to reflect changes in fair values of derivatives attributable to highly effective hedges are either reflected in earnings and largely offset by corresponding adjustments to the hedged items or reflected net of income taxes in accumulated other comprehensive loss until the hedged transaction is recognized in earnings. Changes in the fair value of the derivatives that are not highly effective, if any, are immediately recognized in earnings.

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (CODM). The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid. ASU No. 2023-09 requires a public business entity (PBE) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments in this ASU prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures for all period presented. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows, and financial condition.
