Contract Balances

The contract assets indicated below are presented as prepaid and other current assets in the unaudited condensed consolidated balance sheets. The contract assets are transferred to receivables when the rights to invoice and receive payment become unconditional.

	(in thousands)
Contract assets	205,635	210,557

During the three months ended January 31, 2020 and 2019, the Company recognized $504.5 million and $487.1 million, respectively, of revenue that were included in the deferred revenue balance at the beginning of the period.

Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $4.4 billion as of January 31, 2020, which includes $523.6 million in non-cancellable Flexible Spending Account (FSA) commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. The Company has elected to exclude future sales-based royalty payments from the remaining performance obligations. The contracted but unsatisfied or partially unsatisfied performance obligations expected to be recognized over the next 12 months are approximately 56%, with the remainder recognized thereafter.

During the three months ended January 31, 2020 and 2019, the Company recognized $17.9 million and $18.9 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods.

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 January 31, 2020 were $84.1 million and are included in other assets in the Company’s unaudited condensed consolidated balance sheets. Amortization of these assets was $13.8 million and $12.8 million during the three months ended January 31, 2020 and 2019, respectively, and are included in sales and marketing expense in the Company’s unaudited condensed consolidated statements of operations.
