In addition to results reported in accordance with IFRS, the Company uses certain non-IFRS financial measures as supplemental indicators of its financial and operating performance. These non-IFRS financial measures include adjusted earnings, adjusted earnings per share, adjusted EBITDA, adjusted operating cash flow and adjusted free cash flow. The Company believes these supplementary financial measures reflect the Company's ongoing business in a manner that allows for meaningful period-to-period comparisons and analysis of trends in its business.

The Company defines adjusted earnings as net earnings excluding the impact of specified items affecting comparability, including, where applicable, special income and expense items, amortization of acquisition related intangible assets, share-based compensation, and income tax expense associated with the specified items. The use of the term "special income and expense items" is defined by the Company as those that do not impact operating decisions taken by the Company's management and is based upon the way the Company's management evaluates the performance of the Company's business for use in the Company's internal management reports. These items include: acquisition and integration related expense, interest expense on dissenting shareholder liability, restructuring and enterprise improvement costs, impairment losses and inventory obsolescence, loss from sale of subsidiary, legal settlement  and provision with preferred shareholders, equity in loss from joint ventures and foreign exchange differences. Foreign exchange differences consist of (i) timing differences on certain project-related foreign exchange forward contracts not subject to hedge accounting, (ii) gains and losses on translation of intercompany balances and (iii) unrealized foreign exchange gains and losses on translation of long-term foreign currency denominated financial assets and liabilities. The Company believes that the exclusion of each of these items reduces volatility and provides a more meaningful period-to-period comparison of the Company's ongoing performance. Income tax expense on adjusted earnings is computed using the estimated effective annual income tax rate, adjusted for specific items affecting comparability. Adjusted earnings per share is calculated using diluted weighted average shares outstanding and does not represent actual earnings per share attributable to shareholders. The Company believes that the disclosure of adjusted earnings and adjusted earnings per share allows investors to evaluate the financial performance of the Company's ongoing business using the same evaluation measures that its management uses, and is therefore a useful indicator of the Company's performance.

The Company defines adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, and adjusted for certain items affecting comparability as specified in the calculation of adjusted earnings. Adjusted EBITDA is presented on a basis consistent with the Company's internal management reports. The Company discloses adjusted EBITDA to capture the profitability of its business before the impact of items not considered in management's evaluation of operating unit performance. The Company also discloses segment adjusted EBITDA as a measure of each reporting segment's profitability and contribution to adjusted EBITDA. Segment adjusted EBITDA is reported prior to the deduction of corporate expenses.

The Company defines adjusted operating cash flow as cash provided by operating activities, excluding acquisition and integration expense, less net interest and securitization payments, and other. Adjusted free cash flow is defined as cash provided by operating activities, excluding acquisition and integration related expenses, less net interest and securitization payment, other, and capital expenditures.

Adjusted earnings, adjusted earnings per share, adjusted EBITDA, adjusted operating cash flow, and adjusted free cash flow do not have any standardized meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other companies. The Company cautions readers to consider these non-IFRS financial measures in addition to, and not as an alternative for, measures calculated in accordance with IFRS.

Pro Forma Financial Information

The unaudited pro forma financial information described in this release gives effect to the Company's acquisition of DigitalGlobe using the acquisition method of accounting for business combinations with the Company identified as the acquirer, and is based on the respective historical unaudited condensed consolidated financial statements of the Company and DigitalGlobe for the periods presented herein below. In determining these amounts, management has conformed DigitalGlobe's historical financial results originally prepared under U.S. general accepted accounting principles to IFRS and has assumed that the fair value adjustments, determined provisionally, that arose on the date of acquisition would have been the same if the acquisition had occurred on January 1, 2017. Revenue and direct costs, selling, general and administration expense have been adjusted to reflect the elimination of intra entity transactions during the periods and other expense has been adjusted to reflect the elimination of transaction related expenses.

This unaudited pro forma financial information is for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved if the acquisition had been completed at the beginning of the period for the periods presented, nor do they purport to project the results of operations of the combined entities for any future period or as of any future date. This unaudited pro forma financial information may not be useful in predicting the results of operations of the combined company in the future. The actual results of operations may differ significantly from this pro forma financial information.
