Non-IFRS Financial Measures This press release includes non-IFRS financial measures, including Net electricity costs, Adjusted EBITDA and Adjusted EBITDA Margin. We provide these measures in addition to, and not as a substitute for, measures of financial performance prepared in accordance with IFRS. There are a number of limitations related to the use of Net electricity costs, Adjusted EBTIDA and Adjusted EBITDA Margin. For example, other companies, including companies in our industry, may calculate these measures differently. The Company believes that these measures are important and supplement discussions and analysis of its results of operations and enhances an understanding of its operating performance. EBITDA is calculated as our IFRS profit/(loss) after income tax expense, excluding interest income, finance expense and non-cash fair value loss and interest expense on hybrid financial instruments, income tax expense, depreciation and amortization, which are important components of our IFRS profit/(loss) after income tax expense. Further, “Adjusted EBITDA” also excludes share- based payments expense, which is an important component of our IFRS profit/(loss) after income tax expense, foreign exchange gains and losses, impairment of assets, certain other non-recurring income, loss on disposal of property, plant and equipment, gain on disposal of subsidiaries, unrealized fair value gains and losses on financial assets and certain other expense items. Net electricity costs is calculated as our IFRS Electricity charges net of Realized gain/(loss) on financial asset, ERS revenue (included in Other income) and ERS fees (included in Other operating expenses), and excludes the cost of Renewable Energy Certificates (RECs).
