The representation of performance by business area presented here is based on the approach used by management in monitoring Group performance for the two periods under review, taking account of the operational model adopted by the Group as described above.
With regard to disclosures for operating segments, beginning with the close of the accounts at September 30, 2019, the Enel Group has changed its primary and secondary reporting segments in accordance with the provisions of IFRS 8. Specifically, bearing in mind that in 2019 management began to report performance by business area, the Group has therefore adopted the following reporting sectors:
- Primary sector: business area;
- Secondary sector: geographical area.
The business area is therefore the main discriminant in the analyzes performed and decisions taken by the management of the Enel Group, and is fully consistent with the internal reporting prepared for these purposes since the results are measured and evaluated first and foremost for each business area and only thereafter are they broken down by country. The following chart outlines these organizational arrangements.
In particular, the new organization continues to be based on matrix of Business Lines (Thermal Generation and Trading, Enel Green Power, Infrastructure and Networks, End-user Markets, Enel X, Services and Holding/Other) and geographical areas (Italy, Iberia, Europe and Euro-Mediterranean Affairs, Latin America, North America, Africa, Asia and Oceania, Central/Holding).
Finally, it should be noted that with effect from September 2019, the Latin America area connected with the Enel Green Power Business Line also includes the countries Panama, Costa Rica, Guatemala, El Salvador and Nicaragua, which had previously been reported in the North and Central America geographical area (now renamed North America and consisting of the following countries: United States, Canada and Mexico). In order to ensure full comparability of the figures commented here in the light of the new breakdown of the primary and secondary reporting sectors for IFRS 8 disclosure purposes and of the reallocation of countries in the Enel Green Power segment, the comparative figures for 2018 have been restated appropriately.
