Note 4.- Financial information by segment

Atlantica’s segment structure reflects how management currently makes financial decisions and allocates resources. Its operating and reportable segments are based on the following geographies where the contracted concessional assets are located:

North America

South America

EMEA

Based on the type of business, as of December 31, 2020 the Company had the following business sectors:

Renewable energy

Efficient natural gas

Electric transmission lines

Water

Atlantica’s Chief Operating Decision Maker (CODM), which is the CEO, 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 Adjusted EBITDA as a measure of the performance of each segment. 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.

In order to assess performance of the business, the CODM receives reports of each reportable segment using revenues and 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 years ended December 31, 2020 and December 31, 2019 Atlantica had four customers with revenues representing more than 10% of the total revenues, three in the renewable energy and one in the efficient natural gas business sectors.
