Commercial Aircraft Programs

At September 30, 2024 and December 31, 2023, commercial aircraft programs inventory included the following amounts related to the 737 program: deferred production costs of $8,670 and $6,011 and unamortized tooling and other non-recurring costs of $879 and $792. At September 30, 2024, $9,505 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 $44 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.

At September 30, 2024 and December 31, 2023, commercial aircraft programs inventory included the following amounts related to the 777X program: $3,818 and $4,638 of work in process (including deferred production costs of $552 and $1,792) and $4,255 and $4,063 of unamortized tooling and other non-recurring costs. We expensed abnormal production costs of $442 during the nine months ended September 30, 2023. In the fourth quarter of 2023, the 777X program resumed production, and as a result, there were no abnormal production costs during the nine months ended September 30, 2024. During the third quarter of 2024, we determined that estimated costs to complete the 777X program plus the costs already included in 777X inventory exceed estimated revenues from the program. The resulting reach-forward loss of $2,608 was recorded as a reduction of deferred production costs. The level of profitability on the 777X program will be subject to a number of factors. These factors include aircraft certification requirements and timing, change incorporation on completed aircraft, production disruption due to labor instability (including the ongoing work stoppage) and supply chain disruption, customer delivery timing and negotiations, further production rate adjustments for the 777X or other commercial aircraft programs, and contraction of the accounting quantity. One or more of these factors could result in additional reach-forward losses in future periods.

At September 30, 2024 and December 31, 2023, commercial aircraft programs inventory included the following amounts related to the 787 program: deferred production costs of $12,452 and $12,384, supplier advances of $1,394 and $1,764, and unamortized tooling and other non-recurring costs of $1,402 and $1,480. At September 30, 2024, $11,403 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 $2,451 is expected to be recovered from units included in the program accounting quantity that represent expected future orders. We expensed abnormal production costs of $209 and $937 during the nine months ended September 30, 2024 and 2023.

Commercial aircraft programs inventory included amounts credited in cash or other consideration (early issue sales consideration) to airline customers totaling $4,716 and $4,126 at September 30, 2024 and December 31, 2023.
