On October 19, 2017, one of our subsidiaries, Cobra, and PREPA entered into an emergency master services agreement for repairs to PREPA's electrical grid as a result of Hurricane Maria. The one-year contract, as amended, provided for payments of up to $945 million (the "first contract"). On May 26, 2018, Cobra and PREPA entered into a second one-year,$900 million master services agreement to provide additional repair services and begin the initial phase of reconstruction of the electrical power system in Puerto Rico (the "second contract"). As of December 31, 2023, PREPA owed us approximately $204.8 million for services performed excluding $197.5 million of interest charged on delinquent balances. PREPA is currently subject to bankruptcy proceedings pending in the U.S. District Court for the District of Puerto Rico. As a result, PREPA's ability to meet its payment obligations under the contracts is largely dependent upon funding from the FEMA or other sources. Since September 30, 2019, we have been pursuing litigation in the U.S. District Court for the District of Puerto Rico and other dispute resolution efforts seeking recovery of the amounts owed to Cobra by PREPA for restoration services in Puerto Rico, which proceedings are discussed in more detail in Note 20-"Commitments and Contingencies-Litigation" included elsewhere in this report. In connection with these efforts, in 2023, an aggregate of $99 million was approved by FEMA for reimbursement to Cobra for services performed by Cobra, of which amount approximately $22.2 million was paid by PREPA to Cobra in 2023. On December 1, 2023, Cobra, as seller, and Mammoth, as guarantor, entered into an assignment agreement (the "Assignment Agreement") with SPCP Group, LLC ("SPCP Group"), pursuant to which Cobra transferred to SPCP Group all of its rights, title and interest in $54.4 million of outstanding accounts receivable with PREPA and received net proceeds of $46.1 million. See "-Liquidity and Capital Resources-Cobra Assignment Agreement" for additional information. On December 4, 2023, following submission of a joint status report by Cobra and FEMA on December 1, 2023, in which, among other things, PREPA reported that they submitted a request for reimbursement to the Government of Puerto Rico's Central Recovery and Reconstruction Office ("COR3") on November 1, 2023 for $82.4 million and is disputing approximately $1.5 million of invoices from Cobra, the Court ordered PREPA to provide a detailed summary of each of their objections to the disputed amounts and directed the parties to report the status of any remaining unpaid approved invoices in connection with the status report due on January 16, 2024. On January 16, 2024, the parties filed a joint status report in which, among other things, PREPA reported that on December 28, 2023, it received a disbursement from COR3 for the amount requested on November 1, 2023 and was in the process of paying approximately $13.4 million in approved but unpaid invoices for reimbursements for services performed by Cobra to SPCP Group, as Cobra's assignee, which amount was paid by PREPA on January 18, 2024. PREPA, however, also informed the Court that it will withhold the release of any further funds to Cobra approved by FEMA for reimbursement to Cobra due to the municipal and construction excise tax claims against Cobra allegedly aggregating to $70.4 million. Cobra believes it is exempt from the construction excise taxes and strongly disagrees with PREPA's decision to withhold funds. On January 17, 2024, Cobra filed a Writ of Certiorari requesting the Court of Appeals to reverse the order from the Humacao Superior Court. On February 15, 2024, Cobra's request was granted by the Court of Appeals and the order instructing PREPA to withhold the $9.0 million payment from Cobra was revoked. The case was remanded to the lower Court for continuation of the proceedings in accordance with the Court of Appeals' order. The municipality has 15 days to request reconsideration. On January 19, 2024, the Court extended the previously ordered stay in the proceedings through April 5, 2024, and directed the parties to file a joint status report addressing (i) the status of any administrative appeals in connection with the November 2022 and December 2022 determination memoranda regarding the second contract, (ii) the status of any remaining approved, but unpaid invoices, and (iii) whether the parties are actively engaged in mediation to resolve their outstanding issues by March 27, 2024. Subsequent to December 31, 2023, PREPA paid $64.0 million with respect to the outstanding PREPA receivable, of which $9.6 million was paid to Cobra and $54.4 million was paid to SPCP Group, as Cobra's assignee under the Assignment Agreement, which fully extinguished Cobra's and Mammoth's obligations to SPCP Group under the Assignment Agreement, and the Assignment Agreement was terminated.
We believe all amounts charged to PREPA were properly in accordance with the terms of these contracts. Further, we believe these receivables are collectible. However, in the event PREPA (i) does not have or does not obtain the funds necessary to satisfy its obligations to Cobra under the contracts, (ii) obtains the necessary funds but refuses to pay the amounts owed to us or (iii) otherwise does not pay amounts owed to us for services performed, the receivable may not be collected and our financial condition, results of operations and cash flows would be materially and adversely affected. Further, as noted above, our contracts with PREPA have concluded and we have not obtained, and there can be no assurance that we will be able to obtain, one or more contracts with other customers to replace the level of services that we provided to PREPA.
