Contract Balances

The Company receives payments from customers based upon contractual billing schedules; accounts receivable are recorded when the right to consideration becomes unconditional. Contract assets include amounts related to the contractual right to consideration for completed performance obligations not yet available to be invoiced. Contract liabilities are recorded when cash payments are received in advance of performance, including amounts which are refundable.

The following table provides information on contract assets and contract liabilities from contracts with customers included in the Condensed Consolidated Balance Sheets (in millions):

	As of
	June 30, 2025		December 31, 2024
Short-term contract assets	$	328.0	$	325.7
Contract asset allowances	(17.3)		(24.3)
Short-term contract assets, net	310.7		301.4
Non-current contract assets	69.3		69.0
Contract asset allowances	(2.1)		(2.2)
Non-current contract assets, net included in Other non-current assets	67.2		66.8
Total contract assets, net	$	377.9	$	368.2
Contract liabilities included in Accounts payable and accrued expenses	$	91.5	$	68.0

The amount of revenue recognized during the six months ended June 30, 2025 that was included in the contract liabilities balance at the beginning of the period was $32.6 million. The Company had no material asset impairment charges related to contract assets in the periods presented.

Practical Expedient

The Company incurs incremental costs to obtain new contracts across certain of its service lines. As the amortization period of those expenses is 12 months or less, the Company expenses those incremental costs of obtaining the contracts in accordance with Topic 606.

Remaining performance obligations represent the aggregate transaction prices for contracts where the performance obligations have not yet been satisfied. In accordance with Topic 606, the Company does not disclose unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts for which the Company recognizes revenue in the amount to which we have the right to invoice for services performed and (iii) variable consideration for services performed as a series of daily performance obligations, such as those performed within the Services service line. Performance obligations within such Services contracts represent a significant portion of the Company’s contracts with customers not expected to be completed within 12 months.
