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 is 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. The Company does not expect this proceeding to have a material adverse effect on their financial position, cash flows or results of operations. In the event that the arbitration results in a negative outcome, the Company expects these damages to be covered by the existing insurance policy.

A number of Abengoa's subcontractors and insurance companies that issued bonds covering such contracts in the United States have included subsidiaries of the Company 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 with a potential total claim of approximately $200 million. Based on the assessment of the Company with information currently available, the Company does not expect these proceedings, individually or in the aggregate, to have a material adverse effect on its financial position, cash flows or results of operations.

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.
