Operating results of operating segments are reviewed by the Company’s chief operating decision maker, being the Company’s Chief Executive Officer, to make decisions about resources to be allocated to the segments and to assess their performance. The Company considers its reportable operating segments to be its operating mines and significant development projects. As a result of the Argonaut transaction, the Company has recognized a new operating segment, the Magino mine. The Company operates in two principal geographical areas - Canada, and Mexico. The Young-Davidson, Island Gold and Magino mines operate in Canada, and the Mulatos mine operates in Sonora, Mexico. Significant information relating to the Company's reporting operating segments is as follows:
