NOTE 2. REVENUE FROM CONTRACTS WITH CUSTOMERS
Long-term Contracts
The majority of our contracts are for a period of less than one year. We have certain long-term maintenance agreements, construction contracts and extended warranty coverage arrangements that span a period in excess of one year. The aggregate amount of the transaction price for long-term maintenance agreements and construction contracts allocated to performance obligations that were not satisfied as of July 4, 2021, was $812 million. We expect to recognize the related revenue of $164 million over the next 12 months and $648 million over periods up to 10 years. See Note 10, "PRODUCT WARRANTY LIABILITY," for additional disclosures on extended warranty coverage arrangements. Our other contracts generally are for a duration of less than one year, include payment terms that correspond to the timing of costs incurred when providing goods and services to our customers or represent sales-based royalties.
