Earnings before interest, tax, depreciation and amortisation (EBITDA) is a useful indicator for investors, since it reveals the efficiency of the Group’s activities, including the Group’s ability to finance capital costs, acquire businesses and make other investments, as well as its ability to raise and repay loans. For some investors, analysts and rating agencies, EBITDA normally serves as the ground to evaluate and forecast oil and gas businesses’ cost and efficiency. This indicator should not be viewed separately, as an alternative to earnings for a given period, earnings from core activities or any other indicator showing the Group’s efficiency and reflected in the consolidated financial statement by IFRS.
