All other contract operations revenue is recognized over time.

Performance Obligations

As of June 30, 2020, we had $416.8 million of remaining performance obligations related to our contract operations segment. We do not consider the effects of the time value of money, as the expected time between the transfer of services and payment for such services is less than one year. Our remaining performance obligations will be recognized through 2025 as follows (in thousands):

	2020		2021		2022		2023		2024		2025		Total
Remaining performance obligations	$	172,639	$	170,084	$	65,438	$	7,532	$	1,030	$	79	$	416,802

We do not disclose the aggregate transaction price for the remaining performance obligations for aftermarket services as there are no contracts with customers with an original contract term that is greater than one year.

Contract Assets and Liabilities

As of June 30, 2020 and December 31, 2019, our receivables from contracts with customers, net of allowance for credit losses, were $118.8 million and $139.4 million, respectively.

Freight billings to customers for the transport of compression assets, customer-specified modifications of compression assets and milestone billings on aftermarket services often result in a contract liability. As of June 30, 2020 and December 31, 2019, our contract liabilities were $6.9 million and $11.4 million, respectively, which were included in deferred revenue and other liabilities in our condensed consolidated balance sheets. The decrease in the contract liability balance during the six months ended June 30, 2020 was primarily due to $12.8 million recognized as revenue during the period, partially offset by revenue deferral of $8.3 million, each primarily related to freight billings and milestone billings on aftermarket services.
