The ratio of earnings to fixed charges for the six months ended June 30, 2011 was 12.9. The ratio of earnings to fixed charges represents income before income and mining tax expense, equity income (loss) of affiliates, loss from discontinued operations and net income attributable to noncontrolling interests, divided by interest expense. Interest expense includes amortization of capitalized interest and the portion of rent expense representative of interest. Interest expense does not include interest on income tax liabilities. The computation of the ratio of earnings to fixed charges can be found in Exhibit 12.1.
