Note 18. Revenue from Contracts with Customers

We generate revenue from selling production parts to original equipment manufacturers (OEMs) and service parts to OEMs and aftermarket customers. While we provide production and service parts to certain OEMs under awarded multi-year programs, these multi-year programs do not contain any commitment to volume by the customer. As such, individual customer releases or purchase orders represent the contract with the customer. Our customer contracts do not provide us with an enforceable right to payment for performance completed to date throughout the contract term. As such, we recognize part sales revenue at the point in time when the parts are shipped, and risk of loss has transferred to the customer. We have elected to continue to include shipping and handling fees billed to customers in revenue, while including costs of shipping and handling in costs of sales. Taxes collected from customers are excluded from revenues and credited directly to obligations to the appropriate government agencies. Payment terms with our customers are established based on industry and regional practices and generally do not exceed 180 days. 

We continually seek new business opportunities and at times provide incentives to our customers for new program awards. We evaluate the underlying economics of each payment made to our customers to determine the proper accounting by understanding the nature of the payment, the rights and obligations in the contract, and other relevant facts and circumstances. Upfront payments to our customers are capitalized if we determine that the payments are incremental and incurred only if the new business is obtained and we expect to recover these amounts from the customer over the term of the new business program. We recognize a reduction to revenue as products that the upfront payments are related to are transferred to the customer, based on the total amount of products expected to be sold over the term of the program. We evaluate the amounts capitalized each period for recoverability and expense any amounts that are no longer expected to be recovered. We had $4 and $4 recorded in other current assets and $16 and $27 recorded in other noncurrent assets at June 30, 2025 and December 31, 2024.

Certain of our customer contracts include rebate incentives. We estimate expected rebates and accrue the corresponding refund liability, as a reduction of revenue, at the time covered product is sold to the customer based on anticipated customer purchases during the rebate period and contractual rebate percentages. Refund liabilities are included in other accrued liabilities on our consolidated balance sheets. We provide standard fitness for use warranties on the products we sell, accruing for estimated costs related to product warranty obligations at time of sale. See Note 15 for additional information.

Contract liabilities are primarily comprised of cash deposits made by customers with cash in advance payment terms and upfront payments from customers related to multi-year programs. We had $6 and $6 recorded in other accrued liabilities and $11 and $1 recorded on other noncurrent liabilities at June 30, 2025 and December 31, 2024.
