Contract Balances

The following table represents changes in our contract assets and contract liabilities balances:

	September 30, 2022		December 31, 2021		Year-to-date Change ($)		Year-to-date Change (%)
Contract assets
Accounts receivable, net of allowances	$	276.9	$	236.3	$	40.6	17.2	%

Revenue recognized for the three months ended September 30, 2022 and 2021, that was included in the contract liabilities balance at the beginning of each year was $17.7 and $19.8, respectively. Revenue recognized for the nine months ended September 30, 2022 and 2021 that was included in the contract liabilities balance at the beginning of each year was $114.6 and $97.4, respectively. The amount of revenue recognized during the three and nine months ended September 30, 2022 from performance obligations satisfied or partially satisfied in previous periods as a result of changes in the estimates of variable consideration related to long-term contracts, was not significant.

Remaining Performance Obligations

Remaining performance obligations represent the transaction price of firm signed purchase orders or other written contractual commitments from customers for which work has not been performed, or is partially completed, and excludes unexercised contract options and potential orders. As of September 30, 2022, the estimated revenue expected to be recognized in the future related to remaining performance obligations was $2,254.1. We expect to recognize revenue on approximately 50% to 55% of the remaining performance obligations over the next 12 months and the remaining over the next few years thereafter.
