Atlantica Yield’s Chief Operating Decision Maker (CODM) assesses the performance and assignment of resources according to the identified operating segments. The CODM considers the revenues as a measure of the business activity and the Further Adjusted EBITDA as a measure of the performance of each segment. Further Adjusted EBITDA is calculated as profit/(loss) for the period attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interests from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges of entities included in these consolidated financial statements, and compensation received from Abengoa in lieu of ACBH dividends.

In order to assess performance of the business, the CODM receives reports of each reportable segment using revenues and Further Adjusted EBITDA. Net interest expense evolution is assessed on a consolidated basis. Financial expense and amortization are not taken into consideration by the CODM for the allocation of resources.

In the three-month period ended March 31, 2018 Atlantica had three customers with revenues representing more than 10% of the total revenues, two in the renewable energy and one in the efficient natural gas business sectors. In the three-month period ended March 31, 2017, Atlantica had two customers with revenues representing more than 10% of the total revenues, one in the renewable energy and one in the efficient natural gas business sectors.
