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. Unbilled receivables are presented as accounts receivable, net, in the unaudited condensed consolidated balance sheets.

Contract balances were as follows:

	As of
	January 31, 2022		October 31, 2021
	(in thousands)
Contract assets, net	$	274,009	$	284,574
Unbilled receivables	$	36,324	$	35,589
Deferred revenue	$	2,009,640	$	1,653,926

During the three months ended January 31, 2022, we recognized revenue of $609.5 million that was included in the deferred revenue balance as of October 31, 2021.

Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $6.9 billion as of January 31, 2022, which includes $866.9 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. We have elected to exclude future sales-based royalty payments from the remaining performance obligations. Approximately 41% of the contracted but unsatisfied or partially unsatisfied performance obligations as of January 31, 2022, excluding non-cancellable FSA, are expected to be recognized over the next 12 months, with the remainder recognized thereafter.

During the three months ended January 31, 2022 and 2021, we recognized $32.0 million and $26.3 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods.

Costs of Obtaining a Contract with Customer

Capitalized commission costs, net of accumulated amortization, as of January 31, 2022 were $96.8 million and included in other long-term assets in our unaudited condensed consolidated balance sheets. Amortization of these

assets was $16.7 million and $15.0 million during the three months ended January 31, 2022 and 2021, respectively, and included in sales and marketing expense in our unaudited condensed consolidated statements of income.
