(“Coeur” or “the Company”) is a gold and silver producer with mines located in the United States, Mexico, and Bolivia and exploration projects in Mexico and Argentina. The Company operates the Palmarejo complex, Kensington, Rochester, Wharf, and San Bartolomé mines, and owns Coeur Capital, which is primarily comprised of the Endeavor silver stream, other precious metal royalties, and strategic investments. The cash flow and profitability of the Company's operations are significantly impacted by the market price of gold and silver.</font></div></div>

The preparation of the Company's Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to metal prices and mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production amortization calculations, environmental, reclamation and closure obligations, estimates of recoverable silver and gold in leach pad inventories, estimates of fair value for certain reporting units and asset impairments, valuation allowances for deferred tax assets, and the fair value and accounting treatment of financial instruments, equity securities, and derivative instruments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will differ from the amounts estimated in these financial statements.</font></div></div>
