The contract assets are transferred to receivables when the rights to invoice and receive payment become unconditional. Unbilled receivables are presented as accounts receivable, net, in the unaudited condensed consolidated balance sheets.

Costs of Obtaining a Contract with Customer

The incremental costs of obtaining a contract with a customer, which consist primarily of direct sales commissions earned upon execution of the contract, are required to be capitalized under ASC 340-40 and amortized over the estimated period of which the benefit is expected to be received. As direct sales commissions paid for renewals are commensurate with the amounts paid for initial contracts, the deferred incremental costs will be recognized over the contract term. Total capitalized direct commission costs as of April 30, 2021 were $85.8 million and included in other assets in the Company’s unaudited condensed consolidated balance sheets. Amortization of these assets was $15.5 million and $30.5 million during the three and six months ended April 30, 2021, respectively, and included in sales and marketing expense in the Company’s unaudited condensed consolidated statements of operations. Amortization of these assets was $14.5 million and $28.3 million during the three and six months ended April 30, 2020, respectively, and included in sales and marketing expense in the Company’s unaudited condensed consolidated statements of operations.
