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 December 31, 2023, the aggregate amount of the transaction price allocated to remaining performance obligations was $653 million, of which approximately 82% is expected to be converted to revenue in 2024, approximately 13% 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, as of December 31, 2023 and January 1, 2023 were $18 million and $17 million, respectively, all of which were short-term and recorded in prepaid expenses and other current assets.

Contract liabilities, which consist of deferred revenue and customer deposits, as of December 31, 2023 and January 1, 2023 were $329 million and $308 million, respectively, of which the short-term portions of $252 million and $245 million, respectively, were recorded in accrued liabilities and the remaining long-term portions were recorded in other long-term liabilities.
