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 risk retirements, 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. 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 $415 million and $1.4 billion during the quarter and nine months ended September 27, 2020 and $480 million and $1.5 billion during the quarter and nine months ended September 29, 2019. These adjustments increased net earnings by approximately $328 million ($1.17 per share) and $1.1 billion ($3.82 per share) during the quarter and nine months ended September 27, 2020 and $379 million ($1.33 per share) and $1.2 billion ($4.07 per share) during the quarter and nine months ended September 29, 2019. We recognized net sales from performance obligations satisfied in prior periods of approximately $487 million and $1.5 billion during the quarter and nine months ended September 27, 2020, and $495 million and $1.7 billion during the quarter and nine months ended September 29, 2019, which primarily relate to changes in profit booking rates that impacted revenue. As previously disclosed in our 2019 Form 10-K, 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 September 27, 2020, cumulative losses were approximately $250 million on this program. We may continue to experience issues related to customer requirements and our performance under this contract and have to record additional charges. 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. As previously disclosed in our 2019 Form 10-K, 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. As of September 27, 2020, 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. As previously disclosed in our 2019 Form 10-K, we have two commercial satellite programs at our Space business segment for which we have experienced performance issues related to the development and integration of a modernized LM 2100 satellite platform. These programs are for the delivery of three satellites in total, including two that launched in 2019 and one that launched in February 2020. As of September 27, 2020, cumulative losses to complete these developmental commercial programs remained at approximately $410 million. During the third quarter of 2020, we retired all significant remaining risk to the programs and as a result, we anticipate that no additional losses will be incurred. As previously disclosed in our 2019 Form 10-K, we are responsible for designing, developing and installing an upgraded turret for the Warrior Capability Sustainment Program. In 2018, we revised our estimated costs to complete the program as a consequence of performance issues, and recorded charges at our MFC business segment. As of September 27, 2020, cumulative losses remained at approximately $140 million on this program. We may continue to experience issues related to customer requirements and our performance under this contract and may have to record additional reserves. However, based on the losses already 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. Investment in Advanced Military Maintenance, Repair and Overhaul Center LLC (AMMROC) As of September 27, 2020, we owned 40% of AMMROC, a joint venture located in the United Arab Emirates. We account for our investment in AMMROC using the equity method. AMMROC provides maintenance, repair and overhaul (MRO) and support services for fixed and rotary wing military aircraft in the South Asia, Middle East and North Africa (SAMENA) region. To date, substantially all of AMMROC’s business was dependent on a single customer contract to provide performance based logistics (PBL) services that was in the process of being re-competed. During the first half of 2020, the customer awarded the contract to a competitor. As a result of the loss of this customer contract, we performed a strategic review of AMMROC’s business and evaluated various options for our investment. As a result of this evaluation, we executed an agreement to sell our investment in AMMROC to our joint venture partner for $307 million. Accordingly, in the second quarter of 2020, we adjusted the carrying value of our investment from $435 million to the expected selling price of $307 million, which resulted in the recognition of a noncash impairment charge of $128 million ($96 million, or $0.34 per share, after tax) in our results of operations. The transaction, which is subject to closing conditions, is currently expected to close by early 2021 and the purchase price will be paid in cash installments through September 2021. 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. 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 September 27, 2020, our ending backlog was $150.4 billion. We expect to recognize approximately 37% of our backlog over the next 12 months and approximately 61% over the next 24 months as revenue, with the remainder recognized thereafter. Income Taxes Our effective income tax rate was 14.7% and 15.7% for the quarter and nine months ended September 27, 2020, and 9.7% and 12.5% for the quarter and nine months ended September 29, 2019. The rate for the quarter ended September 29, 2019 was lower primarily due to a $62 million benefit, or $0.22 per share, of additional tax deductions for 2018 attributable to foreign derived intangible income treatment based on proposed tax regulations released on March 4, 2019, and a change in tax accounting method, reflecting a 2012 Court of Federal Claims decision, which held that the tax basis in certain assets should be increased and realized upon the assets' disposition. The rates for all periods benefited from additional tax deductions based on proposed tax regulations released on March 4, 2019, which clarified that foreign military sales qualify for foreign derived intangible income treatment. On July 9, 2020, the U.S. Treasury Department issued final tax regulations related to foreign derived intangible income. The final tax regulations confirm foreign military sales qualify for foreign derived intangible income treatment. We continue to assess the other effects of the final regulations. The rates for all periods also benefited from the research and development tax credit, dividends paid to the corporation's defined contribution plans with an employee stock ownership plan feature, and tax deductions for employee equity awards. Net Loss on Discontinued Operations During the third quarter of 2020, we recognized a $55 million ($0.20 per share) non-cash charge resulting from the resolution of certain tax matters related to the former IS&GS business divested in 2016. May 2020 Debt Issuance On May 20, 2020, we issued a total of $1.2 billion of senior unsecured notes, consisting of $400 million aggregate principal amount of 1.85% Notes due in 2030 (the “2030 Notes”) and $750 million aggregate principal amount of 2.80% Notes due in 2050 (the “2050 Notes” and, together with the 2030 Notes, the “Notes”). We may, at our option, redeem the Notes of any series in whole or in part at any time and from time to time at a redemption price equal to the greater of 100% of the principal amount of the notes to be redeemed or an applicable “make-whole” amount, plus accrued and unpaid interest to the date of redemption. On June 16, 2020, we used the net proceeds from the offering plus cash on hand to redeem $750 million of the outstanding $1.25 billion in aggregate principal amount of our 2.50% Notes due in 2020, and $400 million of the outstanding $900 million in aggregate principal amount of our 3.35% Notes due in 2021 at their redemption price. Sale of Customer Receivables On occasion, our customers may seek deferred payment terms to purchase our products. In connection with these transactions, we may, at our customer’s request, enter into arrangements for the non-recourse sale of customer receivables to unrelated third-party financial institutions. For accounting purposes, these transactions are not discounted and are treated as a sale of receivables as we have no continuing involvement. The sale proceeds from the financial institutions are reflected in our operating cash flows on the statement of cash flows. We sold customer receivables of $160 million and $427 million during the quarter and nine months ended September 27, 2020 and $80 million and $280 million during the quarter and nine months ended September 29, 2019. There were no gains or losses related to sales of these receivables.
