For annual contracts, the Company typically invoices customers at the time of entering into the contract. For multi-year agreements, the Company generally invoices customers on an annual basis prior to each anniversary of the contract start date. The Company records unbilled accounts receivable related to revenue recognized in excess of amounts invoiced as the Company has an unconditional right to invoice and receive payment in the future related to those fulfilled obligations. Invoicing customers prior to performance creates a contract liability, deferred revenue, which is recognized in accordance with the Company’s revenue recognition policy. The following table provides information about unbilled accounts receivable, deferred contract acquisition costs and deferred revenue from contracts with customers (in thousands): As of As of Unbilled accounts receivable, included in accounts receivable, net $ 4,595 $ 5,204 Deferred contract acquisition costs $ 96,037 $ 86,352 Deferred revenue $ 390,313 $ 397,700 Deferred Contract Acquisition Costs Deferred contract acquisition costs represent costs that are incremental to the acquisition of customer contracts, which consist mainly of sales commissions and associated payroll taxes. The Company determines whether costs should be deferred based on sales compensation plans, if the commissions are in fact incremental and would not have occurred absent the customer contract. The Company periodically reviews the carrying amount of deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these deferred costs. The Company did not recognize any impairment of deferred contract acquisition costs during the six months ended October 31, 2021.
