(1) | Total contract retentions included in net contract assets (liabilities) were $89.6 million as of December 31, 2018. Total contract retentions included in net contract assets (liabilities) were $87.1 million as of September 30, 2019, of which $39.7 million are not expected to be paid in the next 12 months. Contract assets at December 31, 2018 and September 30, 2019 include $47.1 million and $58.9 million, respectively, related to unapproved change orders, claims, and requests for equitable adjustment. For the three and nine months ended September 28, 2018 and September 30, 2019, there were no material losses recognized related to the collectability of claims, unapproved change orders, and requests for equitable adjustment.
During the three months ended September 28, 2018 and September 30, 2019, the Company recognized revenue of $0.8 million and $2.1 million, respectively, and $100.4 million and $115.1 million during the nine months ended September 28, 2018 and September 30, 2019, respectively, that was included in the corresponding contract liability balance at December 30, 2017 and December 31, 2018, respectively. The changes in contract assets and contract liabilities were the result of normal business activity and not significantly impacted by other factors, except as follows:
|  | December 31, 2018 |  |  | September 30, 2019 |
Acquired contract assets |  | $ | 35,229 |  |  | $ | 9,747 |

Reversal of provision for contract losses (1) |  | $ | 133,180 |  |  | $ | - |
(1) | Reversal of provision for contract losses of $133.2 million, of which $55.1 million was recorded as an increase in revenue with the remainder recorded as other income.
There was no significant impairment of contract assets recognized during the three and nine months ended September 28, 2018 and September 30, 2019. Revisions in estimates, such as changes in estimated claims or incentives, related to performance obligations partially satisfied in previous periods that individually had an impact of $5 million or more on revenue resulted in an increase in revenue of $9.1 million for the three and nine months ended September 30, 2019, and no amounts for the three and nine months ended September 28, 2018. Accounts Receivable, net Accounts receivable, net consisted of the following as of December 31, 2018 and September 30, 2019 (in thousands):
|  | December 31, 2018 |  |  | September 30, 2019 |
Billed |  | $ | 538,808 |  |  | $ | 516,099 |
Unbilled |  |  | 135,180 |  |  |  | 200,477 |
Total accounts receivable, gross |  |  | 673,988 |  |  |  | 716,576 |
Allowance for doubtful accounts |  |  | (50,702 | ) |  |  | (42,902 | )
Total accounts receivable, net |  | $ | 623,286 |  |  | $ | 673,674 |
Billed accounts receivable represents amounts billed to clients that have not been collected. Unbilled accounts receivable represents amounts where the Company has a present contractual right to bill but an invoice has not been issued to the customer at the period-end date. The allowance for doubtful accounts was determined based on consideration of trends in actual and forecasted credit quality of clients, including delinquency and payment history, type of client, such as a government agency or commercial sector client, and general economic conditions and particular industry conditions that may affect a client’s ability to pay. Transaction Price Allocated to the Remaining Unsatisfied Performance Obligations The Company’s remaining unsatisfied performance obligations (“RUPO”) as of September 30, 2019 represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company had $5.1 billion in RUPO as of September 30, 2019. RUPO will increase with awards of new contracts and decrease as the Company performs work and recognizes revenue on existing contracts. Projects are included within RUPO at such time the project is awarded and agreement on contract terms has been reached. The difference between RUPO and backlog relates to unexercised option years that are included within backlog and the value of Indefinite Delivery/Indefinite Quantity (“IDIQ”) contracts included in backlog for which delivery orders have not been issued. RUPO is comprised of: (a) original transaction price, (b) change orders for which written confirmations from our customers have been received, (c) pending change orders for which the Company expects to receive confirmations in the ordinary course of business, and (d) claim amounts that the Company has made against customers for which it has determined that it has a legal basis under existing contractual arrangements and a significant reversal of revenue is not probable, less revenue recognized to-date. The Company expects to satisfy its RUPO as of September 30, 2019 over the following periods (in thousands):
Period RUPO Will Be Satisfied |  | Within One Year |  |  | Within One to Two Years |  |  | Thereafter |
Federal Solutions |  | $ | 1,198,634 |  |  | $ | 436,620 |  |  | $ | 208,734 |
Critical Infrastructure |  |  | 1,636,525 |  |  |  | 960,469 |  |  |  | 643,170 |
Total |  | $ | 2,835,159 |  |  | $ | 1,397,089 |  |  | $ | 851,904 |
