A summary of the activity impacting our contract balances during the reporting periods is presented below:

As of March 31, 2020, and December 31, 2019, $11.0 million and $10.9 million, respectively, of our deferred contract acquisition costs are included in prepayments and other current assets as they are expected to be amortized within the next 12 months. The remaining amount of our deferred contract acquisition costs are included in other non-current assets. There were no material impairments of deferred contract acquisition costs for the periods ended March 31, 2020 or 2019.

Deferred revenue, which is a contract liability, consists primarily of amounts invoiced in advance of revenue recognition under the Company’s contracts with customers and is recognized as the revenue recognition criteria are met. During the three months ended March 31, 2020 and 2019, revenue recognized that was previously deferred was $46.8 million and $37.5 million, respectively. The difference between the opening and closing balances of the Company’s contract assets and deferred revenue primarily results from the timing difference between the Company’s performance and the customer billings.

Contract assets primarily relate to unbilled amounts, which are netted with deferred revenue at contract level, and typically result from sales contracts when revenue recognized exceeds the amount billed to the customer, and the right to payment is subject to more than the passage of time. Contract assets are transferred to accounts receivable when the rights become unconditional and the customer is billed. Contract assets are included in prepayments and other current assets and other non-current assets in the condensed consolidated balance sheets. During the three months ended March 31, 2020 and 2019, amounts reclassified from contract assets to accounts receivable were $1.5 million and $1.4 million, respectively. There were no material impairments of contract assets during the periods ended March 31, 2020 or 2019.

Our contracts with customers include amounts allocated to performance obligations that will be satisfied at a later date. These remaining performance obligations represent contract revenue that has not yet been recognized and is included in deferred revenue, the balance of which includes both invoices that have been issued to customers but have not been recognized as revenue and amounts that will be invoiced and recognized as revenue in future periods. As of March 31, 2020, amounts allocated to these additional performance obligations are $215.9 million, of which we expect to recognize $143.6 million as revenue over the next 12 months with the remaining balance recognized thereafter.
