"The accountability exercise is an essential part of building transparent relationships based on trust with our stakeholders. In 2005 we prepared the first report with the GRI G.2 methodology, in 2017 we published our latest report with the G.4 methodology and in 2018 we incorporated the guidelines of the GRI Standards, an international methodology for the preparation of sustainability reports in accordance with the Essential option, that is, we report the information necessary to understand the nature of ISAGEN, the relevant management issues, as well as the related impacts and their treatment. In the 2017 Management Report we apply the GRI standards: 101 Fundamentals; GRI: 102 General contents; GRI 103: Management approach; and GRI: 200, 300 and 400 Thematic economic, social and environmental contents. We report at least one content per relevant management topic, we describe the specific information omitted with its reasons, we resort to measurement and calculation techniques supported in the Company's information systems and in case there are variations with respect to the formulas proposed by GRI, we inform you.

We follow the guidelines of the Integrated Reporting Framework (IRC), we take as reference the supplement of the electric sector and we incorporate the guidelines of the AA1000 standards and ISO 26000. This report is, in turn, the Communication of Progress for the Global Compact that indicates our progress in complying with the 10 principles of this initiative, following the requirements of the Advanced Report. On the other hand, we show how we contribute to the Mandate for Water initiative and the Sustainable Development Goals (SDGs) prioritized by ISAGEN, adopting the indicators proposed by the SDG Compass Guide."
