Contract Assets and Liabilities from Contracts with Clients

The timing of revenue recognition, billings and cash collections results in billed receivables (trade receivables), contract assets (unbilled revenue), and contract liabilities (client deposits and deferred revenue) on the condensed consolidated balance sheets. The following table provides information about contract assets (trade receivables and unbilled revenue, excluding allowances for credit losses), and fees invoiced in advance (client deposits and deferred revenue):

	Balance at December 31, 2023		Balance at September 30, 2023
Contract assets: Trade receivables	$	78,472	$	77,618
Contract assets: Unbilled revenue	17,690		17,211
Contract liabilities: Client deposits	16,562		36,689
Contract liabilities: Deferred revenue	19,259		18,933

When the Company does not have the unconditional right to advanced billings, both advanced client payments and unpaid advanced client billings are excluded from deferred revenue, with the advanced billings also being excluded from client receivables. The Company excluded approximately $18,164 and $10,220 of unpaid advanced client billings from both client receivables and deferred revenue as of December 31, 2023 and September 30, 2023, respectively.

Changes in the contract asset and the contract liability balances during the three months ended December 31, 2023 include the following:

•Changes in the time frame for a right for consideration to become unconditional – approximately 50.0% of unbilled revenue as of September 30, 2023, was billed during the three months ended December 31, 2023; and

•Changes in the time frame for a performance obligation to be satisfied – approximately 51.0% of deferred revenue as of September 30, 2023, was recognized as revenue during the three months ended December 31, 2023.
