Contracts with Multiple Performance Obligations Some of our contracts with customers contain multiple performance obligations. For these contracts, we account for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. We determine the standalone selling prices based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the cloud applications sold, customer demographics, geographic locations, and the number and types of users within our contracts. We considered several factors in determining that control transfers to the customer upon shipment of hardware and availability of download of software. These factors include that legal title transfers to the customer, we have a present right to payment, and the customer has assumed the risks and rewards of ownership. Accounts receivable from our customers are typically due within 30 not Costs to Obtain and Fulfill a Contract Costs to obtain and fulfill a contract are predominantly sales commissions earned by our sales force and are considered incremental and recoverable costs of obtaining a contract with a customer.
