At June 30, 2023 and December 31, 2022, commercial aircraft programs inventory included the following amounts related to the 737 program: deferred production costs of $4,739 and $2,955 and unamortized tooling and other non-recurring costs of $591 and $626. At June 30, 2023, $5,297 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 $33 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.

At June 30, 2023 and December 31, 2022, commercial aircraft programs inventory included the following amounts related to the 777X program: $4,226 and $4,059 of work in process, $1,385 and $1,330 of deferred production costs, and $3,868 and $3,774 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 $262 and $102 during the six months ended June 30, 2023 and 2022. The 777X program has near break-even margins at June 30, 2023.

At June 30, 2023, $11,823 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 $1,970 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 $693 and $595 during the six months ended June 30, 2023 and 2022.
