The balances of the Partnership’s contract assets and contract liabilities as of September 30, 2020 and December 31, 2019 are as follows:

	September 30, 2020		December 31, 2019

Contract liability	$	—	$	—

The amount of revenue recognized in the three and nine months ended September 30, 2020 that was included in the contract liability balance at the beginning of each period was $0.1 million and $0.3 million, respectively, and $0.1 million and $0.3 million in the three and nine months ended September 30, 2019, respectively. This amount of revenue is a result of changes in the transaction price of the Partnership’s contracts with customers. The difference in the opening and closing balances of the contract asset and contract liability primarily results from the timing difference between the Partnership’s performance and the customer’s payment.
