At March 31, 2023 and December 31, 2022, commercial aircraft programs inventory included the following amounts related to the 737 program: deferred production costs of $3,913 and $2,955 and unamortized tooling and other non-recurring costs of $606 and $626. At March 31, 2023, $4,493 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 March 31, 2023 and December 31, 2022, commercial aircraft programs inventory included the following amounts related to the 777X program: $4,154 and $4,059 of work in process, $1,310 and $1,330 of deferred production costs, and $3,820 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 $126 during the three months ended March 31, 2023. The 777X program has near break-even margins at March 31, 2023.

At March 31, 2023, $10,211 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 $3,916 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 $379 and $312 during the three months ended March 31, 2023 and 2022.

Commercial aircraft programs inventory included amounts credited in cash or other consideration (early issue sales consideration) to airline customers totaling $3,559 and $3,586 at March 31, 2023 and December 31, 2022.
