Performance Obligations

We regularly enter into contracts with multiple performance obligations. These contracts are believed to be firm as of the balance sheet date. However, we may allow customers to make product substitutions as we launch new products. The timing of shipments depends on several factors, including agreed upon shipping schedules, which may span multiple quarters. Most performance obligations are generally satisfied within a short time frame, approximately three tosix months, after the contract execution date. As of March 31, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $796 million, of which approximately 87% is expected to be converted to revenue in the next twelve months, approximately 9% in the following twelve months, and the remainder thereafter.

Contract Assets and Liabilities

Contract assets, which consist of revenue recognized and performance obligations satisfied or partially satisfied in advance of customer billing, were $15 million and $18 million as of March 31, 2024 and December 31, 2023, respectively, and were recorded in prepaid expenses and other current assets.
