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
	April 30, 2022		October 31, 2021
	(in thousands)
Contract assets, net	$	235,705	$	284,574
Unbilled receivables	$	38,022	$	35,589

During the three and six months ended April 30, 2022, we recognized revenue of $327.5 million and $937.0 million, respectively, that was included in the deferred revenue balance as of October 31, 2021.

Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $7.3 billion as of April 30, 2022, which includes $1.0 billion 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 April 30, 2022, excluding non-cancellable FSA, are expected to be recognized over the next 12 months, with the remainder recognized thereafter.
