Commercial Aircraft Programs

The decrease in commercial aircraft programs inventory during 2022 reflects a decrease in 737 and 787 inventory, offset by growth in 777X inventory. Commercial aircraft programs inventory includes approximately 250 737 aircraft and 100 787 aircraft at December 31, 2022 as compared with 335 737 aircraft and 110 787 aircraft at December 31, 2021.

At December 31, 2022 and 2021, commercial aircraft programs inventory included the following amounts related to the 737 program: deferred production costs of $2,955 and $1,296 and unamortized tooling and other non-recurring costs of $626 and $617. At December 31, 2022, $3,555 of 737 deferred production costs, unamortized tooling and other non-recurring costs are expected to be recovered from units included in the program accounting quantity that have firm orders, and $26 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.

At December 31, 2022 and 2021, commercial aircraft programs inventory included the following amounts related to the 777X program: $4,059 and $3,363 of work in process, $1,330 and $652 of

deferred production costs, and $3,774 and $3,521 of unamortized tooling and other non-recurring costs. In April 2022, we decided to pause production of the 777X-9 during 2022 and 2023. The production pause is resulting in abnormal production costs that are being expensed as incurred until 777X-9 production resumes. We expensed abnormal production costs of $325 during the year ended December 31, 2022. The 777X program has near break-even margins at December 31, 2022.

During the fourth quarter of 2021, we determined that estimated costs to complete the 787 program plus costs already included in 787 inventory exceed estimated revenues from the program. The resulting reach-forward loss of $3,460 was recorded as a reduction to deferred production costs. At December 31, 2022 and 2021, commercial aircraft programs inventory included the following amounts related to the 787 program: deferred production costs of $12,689 and $11,693, $1,831 and $1,907 of supplier advances, and $1,722 and $1,815 of unamortized tooling and other non-recurring costs. At December 31, 2022, $9,881 of 787 deferred production costs, unamortized tooling and other non-recurring costs are expected to be recovered from units included in the program accounting quantity that have firm orders, and $4,530 is expected to be recovered from units included in the program accounting quantity that represent expected future orders. We are currently producing at abnormally low rates resulting in abnormal production costs that are being expensed as incurred. We expensed abnormal production costs of $1,240 and $468 during the years ended December 31, 2022 and 2021.

Commercial aircraft programs inventory included amounts credited in cash or other consideration (early issue sales consideration) to airline customers totaling $3,586 and $3,290 at December 31, 2022 and 2021.
