OTHER	OTHER Changes in Estimates Significant estimates and assumptions are made in estimating contract sales and costs, including the profit booking rate. 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 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 surrounding the 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 determined. In addition, 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 for which we recognize revenue over time using the percentage-of-completion cost-to-cost method to measure progress towards completion. 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 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 charges, insurance recoveries and gains on sales of assets. Unfavorable items may include the adverse resolution of contractual matters; 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 adjustments not related to volume, including net profit booking rate adjustments and other matters, increased segment operating profit by approximately $405 million during the quarter ended March 27, 2022 and $495 million during the quarter ended March 28, 2021. These adjustments increased net earnings by approximately $320 million ($1.19 per share) during the quarter ended March 27, 2022 and $391 million ($1.40 per share) during the quarter ended March 28, 2021. We recognized net sales from performance obligations satisfied in prior periods of approximately $416 million during the quarter ended March 27, 2022, and $492 million during the quarter ended March 28, 2021, which primarily relate to changes in profit booking rates that impacted revenue. 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. As of March 27, 2022, cumulative losses remained at approximately $225 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, which could be material to our operating results. In addition, we and our industry team will incur advanced procurement costs (also referred to as precontract costs) in order to enhance our ability to achieve the revised schedule and certain milestones. We will monitor the recoverability of precontract 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 accrued reserves. As of March 27, 2022, 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 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 operating results or financial condition. We have a program, EADGE-T, to design, integrate and install an air missile defense command, control, communications, computers - intelligence (C4I) system for an international customer that has experienced performance issues and for which we have periodically accrued reserves at our RMS business segment. We last recorded a charge and accrued reserves for this program in 2017. As of March 27, 2022, cumulative losses remained at approximately $260 million. We continue to monitor program requirements and our performance. At this time, we do not anticipate additional charges that would be material to our operating results or financial condition. Backlog 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. Our backlog includes both funded (firm orders for our products and services for which funding has been both authorized and appropriated by the customer) and unfunded (firm orders for which funding has not been appropriated) amounts. We do not include unexercised options or potential orders under indefinite-delivery, indefinite-quantity agreements in our backlog. 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 March 27, 2022, our ending backlog was $134.2 billion. We expect to recognize approximately 38% of our backlog over the next 12 months and approximately 61% over the next 24 months as revenue with the remainder recognized thereafter. Lockheed Martin Ventures Fund Through our Lockheed Martin Ventures Fund, we make strategic investments in companies that we believe are advancing or developing new technologies applicable to our business. These investments may be in the form of common or preferred stock, warrants, convertible debt securities or investments in funds. Most of the investments are in equity securities without readily determinable fair values, 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. Investments with quoted market prices in active markets (Level 1) are recorded at fair value at the end of each reporting period. The carrying amounts of investments held in our Lockheed Martin Ventures Fund were $575 million and $465 million at March 27, 2022 and December 31, 2021. During the quarters ended March 27, 2022 and March 28, 2021, we recorded net gains of $103 million ($77 million, or $0.29 per share, after-tax) and $68 million ($51 million, or $0.18 per share, after-tax) due to changes in fair value and/or sales of investments which are reflected in the other non-operating income, net account on our consolidated statements of earnings. Income Taxes Our effective income tax rate was 15.9% and 16.9% for the quarters ended March 27, 2022 and March 28, 2021. The rate for the first quarter of 2022 is lower due to increased tax deductions for employee equity awards and foreign derived intangible income compared to the first quarter of 2021. The rates for both periods benefited from the research and development tax credit and dividends paid to our defined contribution plans with an employee stock ownership plan feature. Severance and Restructuring Charges During the first quarter of 2021, we recorded severance and restructuring charges of $36 million ($28 million, or $0.10 per share, after-tax) related to workforce reductions and facility exit costs within our RMS business segment. These actions were taken to consolidate certain operations in order to improve the efficiency of RMS’ manufacturing operations and affordability of its products and services. Employees terminated as part of these actions were to receive lump-sum severance payments upon separation primarily based on years of service.
