Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by revenue for the corresponding period. Adjusted EBITDA is not intended to represent cash flow from operations, as defined by IFRS, and should not be considered as alternatives to net profit (loss) from operations, or any other measure of performance prescribed by IFRS. Adjusted EBITDA, as we define and use it, may not be comparable to Adjusted EBITDA as defined and used by other companies. We consider Adjusted EBITDA to be a meaningful measure to assess our operating performance in addition to IFRS measures. It is included because we believe it can be useful in measuring our operating performance and our ability to expand our business and provide management and investors with additional information for comparison of our operating results across different time periods and to the operating results of other companies. Adjusted EBITDA is also used by analysts and our lenders as a measure of our financial performance. In addition, we consider Adjusted EBITDA margin to be a useful measure of our operating performance and profitability across different time periods that enhance the comparability of our results.
