Multiple-Element Transactions
From time to time, we enter into transactions involving multiple elements. We analyze contracts with multiple elements under the accounting guidance for revenue recognition in multiple-element arrangements. If we enter into transactions for the sale of multiple products or services, we evaluate whether the delivered elements have value to the customer on a stand-alone basis, and whether there is objective and reliable evidence of fair value for each undelivered element in the transaction. If these criteria are met, then we account for each deliverable in the transaction separately. We generally recognize revenue for undelivered elements on a straight-line basis over the contractual performance period for time-based elements or upon delivery to the customer. If we are unable to determine the fair value of one or more undelivered elements in the transaction, we recognize the revenue on a straight-line basis over the period in which the last deliverable is provided to the customer.
Multiple-element transactions require judgment to determine the selling price or fair value of the different elements. The judgments impact the amount of revenue and expenses recognized over the term of the contract, as well as the period in which they are recognized.
