(a)   The Company’s continuous disclosure documents provide discussion and analysis of “EBITDA”, “EBITDA per share”, “shareholder free cash flow” and “shareholder free cash flow per share”. These financial measures do not have standard definitions prescribed by IFRS and, therefore, may not be comparable to similar measures disclosed by other companies. The Company has included these non-GAAP financial measures because management, investors, analysts and others use them as measures of the Company’s financial performance. The Company’s definition of EBITDA is cash available for interest payments, cash taxes, repayment of debt, purchase of its shares, discretionary capital expenditures and the payment of dividends, and is calculated as earnings or loss from operations before interest, taxes, depreciation and amortization. The Company believes EBITDA assists investors in comparing Pulse’s results on a consistent basis without regard to non-cash items, such as depreciation and amortization, which can vary significantly depending on accounting methods or non-operating factors such as historical cost. EBITDA per share is defined as EBITDA divided by the weighted average number of shares outstanding for the period. Shareholder free cash flow further refines the calculation of capital available to invest in growing the Company’s 2D and 3D seismic data library, to repay debt, to purchase its common shares and to pay dividends by deducting non-discretionary expenditures from EBITDA. Non-discretionary expenditures are defined as non-cash expenses, debt financing costs (net of deferred financing expenses amortized in the current period), net restructuring costs and current tax provisions. Shareholder free cash flow per share is defined as shareholder free cash flow divided by the weighted average number of shares outstanding for the period.
These non-GAAP financial measures are defined, calculated and reconciled to the nearest GAAP financial measures in the Management’s Discussion and Analysis.
