Non-GAAP Measures

Silver Wheaton has included certain non-GAAP performance measures, including total cash costs of silver and gold on a sales basis, as well as operating cash flows per share and cash operating margin. These non-GAAP measures do not have any standardized meaning prescribed by GAAP, nor are they necessarily comparable with similar measures presented by other companies. Cash costs are presented as they represent an industry standard method of comparing certain costs on a per unit basis. Cash operating margin is defined as the realized selling price less total cash cost per silver equivalent ounce. The Company believes that certain investors use this information to evaluate the Company’s performance. The data is 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. During the three months ended June 30, 2010, the Company’s total cash costs, which were equivalent to the Company’s cost of sales in accordance with GAAP, were US$3.97 per ounce of silver and US$300 per ounce of gold (three months ended June 30, 2009 – US$3.97 per ounce of silver and US$300 per ounce of gold).
