Change in Accounting Estimate [Abstract] |
Changes in Estimates | Note Q — Changes in Estimates Under the POC cost-to-cost method of revenue recognition, a single estimated profit margin is used to recognize profit for each performance obligation over its period of performance. Recognition of profit on a contract requires estimates of the total cost at completion and transaction price and the measurement of progress towards completion. Due to the long-term nature of many of our contracts, developing the estimated total cost at completion and total transaction price often requires judgment. Factors that must be considered in estimating the cost of the work to be completed include the nature and complexity of the work to be performed, subcontractor performance and the risk and impact of delayed performance. Factors that must be considered in estimating the total transaction price include contractual cost or performance incentives (such as incentive fees, award fees and penalties) and other forms of variable consideration as well as our historical experience and our expectation for performance on the contract. These variable amounts generally are awarded upon achievement of certain negotiated performance metrics, program milestones or cost targets and can be based upon customer discretion. We include such estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. At the outset of each contract, we gauge its complexity and perceived risks and establish an estimated total cost at completion in line with these expectations. After establishing the estimated total cost at completion, we follow a standard Estimate at Completion (“EAC”) process in which we review the progress and performance on our ongoing contracts at least quarterly and, in many cases, more frequently. If we successfully retire risks associated with the technical, schedule and cost aspects of a contract, we may lower our estimated total cost at completion commensurate with the retirement of these risks. Conversely, if we are not successful in retiring these risks, we may increase our estimated total cost at completion. Additionally, as the contract progresses, our estimates of total transaction price may increase or decrease if, for example, we receive award fees that are higher or lower than expected. When adjustments in estimated total costs at completion or in estimated total transaction price are determined, the related impact on operating income is recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Any anticipated losses on these contracts are fully recognized in the period in which the losses become evident. Net EAC adjustments had the following impact to earnings for the periods presented:
| Quarter Ended |  | Three Quarters Ended
(In millions, except per share amounts) | October 1, 2021 |  | October 2, 2020 |  | October 1, 2021 |  | October 2, 2020
Net EAC adjustments, before income taxes | $ | 85 |  |  | $ | 99 |  |  | $ | 247 |  |  | $ | 300 |
Net EAC adjustments, net of income taxes | 64 |  |  | 74 |  |  | 186 |  |  | 225 |
Net EAC adjustments, net of income taxes, per diluted common share | 0.32 |  |  | 0.34 |  |  | 0.91 |  |  | 1.03 |
Revenue recognized from performance obligations satisfied in prior periods was $102 million and $317 million for the quarter and three quarters ended October 1, 2021, respectively, and $121 million and $359 million for the quarter and three quarters ended October 2, 2020, respectively.
