All financial information presented in this AIF was prepared in accordance with international financial reporting standards (“IFRS”) as issued by the International Accounting Standards Board. Non-GAAP Measures This AIF refers to various non-generally accepted accounting principles (“non-GAAP”) measures, such as cash cost per payable ounce of silver, net of by-product credits (“cash costs”), all-in sustaining costs per silver ounce sold (“AISCSOS”), working capital and total debt. Cash Costs This AIF presents information about our cash costs for our operating mines. Except as otherwise noted, cash costs is calculated by dividing total cash costs net of by-product credits by total payable silver ounces produced at the relevant mine or mines. Total cash costs include mine operating costs such as mining, processing, administration and royalties, but exclude amortization, reclamation costs, financing costs and capital development and exploration. Certain amounts of stock-based compensation are excluded as well. Cash costs is included in this AIF because certain investors use this information to assess our performance and also to determine our ability to generate cash flow for use in investing and other activities. The inclusion of cash costs may enable investors to better understand year-over-year changes in our production costs, which in turn affect profitability and cash flow. Cash costs does not have a standardized meaning or a consistent basis of calculation prescribed by IFRS. Investors are cautioned that cash costs should not be considered in isolation or construed as a substitute to costs determined under IFRS as an indicator of performance. Our method of calculating cash costs may differ from the methods used by other entities and, accordingly, our cash costs may not be comparable to similarly titled measures used by other entities. Readers should refer to our management’s discussion and analysis for the year ended December 31, 2017 (the “2017 MD&A”) for a detailed description and reconciliation of this non-GAAP measure.

The Company believes that AISCSOS reflects a comprehensive measure of the full cost of operating its consolidated business given it includes the cost of replacing ounces through exploration, the cost of ongoing capital investment (sustaining capital), general and administrative expenses, direct operating costs, as well as other items that affect the Company’s consolidated earnings and cash flow. AISCSOS does not have a standardized meaning or a consistent basis of calculation prescribed by IFRS.
