NON-GAAP MEASURE - AISC

The Company uses certain non-GAAP financial measures to assist in understanding the Company's financial results, including all-in sustaining costs (“AISC”) per gold equivalent ounce. AISC is employed by the Company to measure its operating and economic performance and to assist in decision-making, as well as to provide key performance information to senior management. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, certain investors and other stakeholders will find this information useful to evaluate the Company's operating and financial performance; however, non-GAAP performance measures such as AISC do not have any standardized meaning. These performance measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. These non-GAAP measures should be read in conjunction with the Company's consolidated financial statements.
AISC includes total cost of sales incurred at the Company's mining operations, which forms the basis of its cash costs, and which are reconciled to reported cost of sales in the Company’s financial statements. Additionally, the Company includes sustaining capital expenditures, sustaining mine-site exploration and evaluation costs, reclamation cost accretion and amortization, and general and administrative expenses. This measure seeks to reflect the ongoing cost of gold and silver production from current operations; therefore, expansionary capital and non-sustaining expenditures are excluded. Certain other cash expenditures, including tax payments and financing costs are also excluded.
The Company believes that AISC represents the total costs of producing gold and silver from current operations and provides the Company and other stakeholders with additional information about its operating performance and ability to generate cash flows. It allows the Company to assess its ability to support capital expenditures and to sustain future production from the generation of operating cash flows. When deriving the number of ounces of precious metal sold, the Company considers the physical ounces available for sale after the treatment and refining process, commonly referred to as payable metal, as this is what is sold to third parties.
