Variable Consideration

Certain clients may receive volume-based rebates or early payment discounts, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be earned by our clients and reduce revenue accordingly. We do not expect significant changes to estimates of variable consideration. Given the nature of our products and the history of returns, product returns are not significant.

Contract Balances

The following table provides information about contract liabilities from contracts with clients:

	Contract Liabilities
	Short-Term
Balance at December 31, 2020	$15.6
Balance at September 30, 2021	$12.7

Contract liabilities primarily relate to client advances received prior to completion of performance obligations. Reductions in contract liabilities are a result of our completion of performance obligations.

Revenue recognized during the nine months ended September 30, 2021 from amounts included in contract liabilities at the beginning of the period was $13.1 million.
