(9) To supplement our gross profit presented in accordance with IFRS, we use the non-IFRS financial measure of adjusted gross profit, which is adjusted from gross profit, the most comparable IFRS measure, to exclude depreciation and amortization expense and share-based compensation expense included in cost of revenues. For a reconciliation of gross profit to adjusted gross profit, see footnote (11). We also present the non-IFRS financial measure of adjusted gross profit margin percentage, which reflects adjusted gross profit margin as a percentage of revenues. We also present the non-IFRS financial measure of adjusted selling, general and administrative expenses margin percentage, which reflects adjusted selling, general and administrative expenses as a percentage of revenues. To supplement our selling, general and administrative expenses presented in accordance with IFRS, we use the non-IFRS financial measure of adjusted selling, general and administrative expenses, which is adjusted from selling, general and administrative expenses, the most comparable IFRS measure, to exclude acquisition-related charges, net, depreciation and amortization expense and share-based compensation expense included in selling, general and administrative expenses. For a reconciliation of selling, general and administrative expenses to adjusted selling, general and administrative expenses, see footnote (11). We believe that excluding such acquisition-related charges, net, depreciation and amortization and share-based compensation expense amounts from gross profit and selling, general and administrative expenses and acquisition-related charges, net, depreciation and amortization expense and share-based compensation expense included in cost of revenues as a percentage of revenues from gross profit margin helps investors compare us and similar companies that exclude acquisition-related charges, net, depreciation and amortization expense and share-based compensation expense from gross profit and selling, general and administrative expenses and acquisition-related charges, net, depreciation and amortization expense and share-based compensation expense included in cost of revenues as a percentage of revenues from gross profit margin. These non-IFRS financial measures are provided as additional information to enhance investors’ overall understanding of the historical and current financial performance of our operations. We believe these measures help illustrate underlying trends in our business and use such measures to establish budgets and operational goals, communicated internally and externally, for managing our business and evaluating its performance. These non-IFRS financial measures should be considered in addition to results prepared in accordance with IFRS, but should not be considered as substitutes for or superior to IFRS results. In addition, our calculation of these non-IFRS financial measures may be different from the calculation used by other companies, and therefore comparability may be limited.
