AGNICO EAGLE MINES LTD

Operating margin is calculated by deducting production costs from revenue from mining operations. In order to reconcile operating margin to net income as recorded in the consolidated financial statements, the Company adds the following items to the operating margin: income and mining taxes expense; other expenses (income); care and maintenance expenses; foreign currency translation (gain) loss; environmental remediation costs; gain (loss) on derivative financial instruments; finance costs; general and administrative expenses; amortization of property, plant and mine development; exploration and corporate development expenses; revaluation gain and impairment losses (reversals). The Company believes that operating margin is a useful measure to investors as it reflects the operating performance of its individual mines associated with the ongoing production and sale of gold and by-product metals without allocating Company-wide overhead, such as exploration and corporate development expenses, amortization of property, plant and mine development, general and administrative expenses, finance costs, gain and losses on derivative financial instruments, environmental remediation costs, foreign currency translation gains and losses, other expenses and income and mining tax expenses. Management uses this measure internally to plan and forecast future operating results. Management believes this measure is helpful to investors as it provides them with additional information about the Company’s underlying operating results, though it should be evaluated in conjunction with other data prepared in accordance with IFRS.
