Revenue from Contract with Customers [Abstract] |
Revenue from Contract with Customer [Text Block] | 11. REVENUE FROM CONTRACTS WITH CUSTOMERS The guidance in ASC 606 - Revenue from Contracts with Customers is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We are obligated under our contracts with customers to manufacture and supply products for use in our customers’ operations. We satisfy these performance obligations at the point in time that the customer obtains control of the products, which is the point in time that the customer is able to direct the use of, and obtain substantially all of the remaining benefits from, the products. This typically occurs upon shipment to the customer in accordance with purchase orders and delivery releases issued by our customers. There is judgment involved in determining when the customer obtains control of the products and we have utilized the following indicators of control in our assessment: •We have the present right to payment for the asset; •The customer has legal title to the asset; •We have transferred physical possession of the asset; •The customer has the significant risks and rewards of ownership of the asset; and •The customer has accepted the asset. Our product offerings by segment are as follows: •Driveline products consist primarily of front and rear axles, driveshafts, differential assemblies, clutch modules, balance shaft systems, disconnecting driveline technology, and electric and hybrid driveline products and systems for light trucks, sport utility vehicles (SUVs), crossover vehicles (CUVs), passenger cars and commercial vehicles; and •Metal Forming products consist primarily of engine, transmission, driveline and safety-critical components for traditional internal combustion engine and electric vehicle architectures including light vehicles, commercial vehicles and off-highway vehicles, as well as products for industrial markets. Our contracts with customers, which are comprised of purchase orders and delivery releases issued by our customers, generally state the terms of the sale, including the quantity and price of each product purchased. Trade accounts receivable from our customers are generally due approximately 50 days from the date our customers receive our product. Our contracts typically do not contain variable consideration as the contracts include stated prices. We provide our customers with assurance type warranties, which are not separate performance obligations and are outside the scope of ASC 606. Refer to Note 10 - Commitments and Contingencies for further information on our product warranties. Disaggregation of Net Sales Net sales recognized from contracts with customers, disaggregated by segment and geographical location, are presented in the following table for the years ended December 31, 2024, 2023 and 2022. Net sales are attributed to regions based on the location of production. Intersegment sales have been excluded from the table.

Contract Assets and Liabilities The following table summarizes our beginning and ending balances for accounts receivable and contract liabilities associated with our contracts with customers (in millions):
| Accounts Receivable, Net | Contract Liabilities (Current) | Contract Liabilities (Long-term)
December 31, 2023 | $ | 818.5 |  | $ | 16.6 |  | $ | 70.4 |

Increase/(decrease) | $ | (109.4) |  | $ | (2.4) |  | $ | (33.4) |
Contract liabilities relate to deferred revenue associated with various settlements and commercial agreements for which we have future performance obligations to the customer. We recognize this deferred revenue into revenue over the life of the associated program as we satisfy our performance obligations to the customer. We do not have contract assets as defined in ASC 606. During the twelve months ended December 31, 2024 and December 31, 2023 we amortized $18.7 million and $30.2 million, respectively, of previously recorded contract liabilities into revenue as we satisfied performance obligations with our customers. In 2024, we were notified by a customer that AAM was no longer obligated to provide product for a vehicle program that was expected to launch in the future. Prior to this notification, we had capitalized $19.8 million of engineering, design and development (ED&D) costs into Other assets and deferred charges and had also recorded $19.8 million of ED&D reimbursements in Deferred revenue in our Consolidated Balance Sheet. As a result of this customer notification in the third quarter of 2024, we removed these balances thereby reducing both Other assets and deferred charges and Deferred revenue by $19.8 million.
