Legal Proceedings

On October 17, 2016, ACT received a request for arbitration from the International Court of Arbitration of the International Chamber of Commerce presented by Pemex. Pemex was requesting compensation for damages caused by a fire that occurred in their facilities during the construction of the ACT cogeneration plant in December 2012, for a total amount of approximately $20 million. On July 5, 2017, Seguros Inbursa, the insurer of Pemex, joined as a second claimant in the process. In September 2018, ACT was notified that an agreement was reached between insurance companies according to which ACT would not have to pay any amount in relation to this arbitration. On December 19, 2018 the parties of the arbitration executed a settlement agreement to finalize the claim without any financial impact for ACT.

A number of Abengoa’s subcontractors and insurance companies that issued bonds covering Abengoa’s obligations under such contracts in the United States have included some of the non-recourse subsidiaries of the Company in the United States as co-defendants in claims against Abengoa. Generally, the subsidiaries of the Company have been dismissed as defendants at early stages of the processes but there remain pending cases including Arb Inc. with a potential total claim of approximately $33 million and a group of insurance companies that have addressed to a number of Abengoa’s subsidiaries and to Solana (Arizona Solar One) a potential claim for Abengoa related losses of approximately $20 million that could increase, according to the insurance companies, up to a maximum of up to approximately $200 million if all their exposure resulted in losses. The Company reached an agreement with Arb Inc. and all but one of the above-mentioned insurance companies, under which they agreed to dismiss their claims in exchange for payments of approximately $6.6 million, which have been made in 2018. The insurance company which did not join the agreement has temporarily stopped legal actions against the Company and the Company does not expect to have a material adverse effect.

In addition, an insurance company covering certain Abengoa’s obligations in Mexico has claimed certain amounts related to a potential loss. This claim is covered by existing indemnities from Abengoa. Nevertheless, the Company has reached an agreement under which Atlantica´s maximum theoretical exposure would in any case be limited to approximately $35 million, including $2.5 million to be held in an escrow account. On January 2019, the insurance company executed $2.5 million from the escrow account and Abengoa reimbursed such amount according to the existing indemnities in force between Atlantica and Abengoa. The payments by Atlantica would only happen if and when the actual loss has been confirmed, Abengoa has not fulfilled their obligations and after arbitration, if the Company initiates it.

The Company is not a party to any other significant legal proceeding other than legal proceedings arising in the ordinary course of its business. The Company is party to various administrative and regulatory proceedings that have arisen in the ordinary course of business. While the Company does not expect these proceedings, either individually or in the aggregate, to have a material adverse effect on its financial position or results of operations, because of the nature of these proceedings the Company is not able to predict their ultimate outcomes, some of which may be unfavorable to the Company.
