REVENUE FROM CONTRACTS WITH CUSTOMERS
NOTE 2. REVENUE FROM CONTRACTS WITH CUSTOMERS
Long-term Contracts
We have certain arrangements, primarily long-term maintenance agreements, construction contracts, product sales with associated performance obligations extending beyond a year, product sales with lead times extending beyond one year that are non-cancellable or for which the customer incurs a penalty for cancellation and extended warranty coverage arrangements that span a period in excess of one year. The aggregate amount of the transaction price for these contracts, excluding extended warranty coverage arrangements, at March 31, 2026, was $6.9 billion. We expect to recognize the related revenue of $4.0 billion over the next 12 months and $2.9 billion 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.
