e) Forward Purchase Commitments 

We have a number of forward purchase commitments for the purchase of concentrates, for shipping and distribution of products and for other process inputs, which are incurred in the normal course of business. During the year, we entered into arrangements for the purchase of power in future periods for the expansion of our Quebrada Blanca Operations. The majority of these contracts are subject to force majeure  provisions. 

f) Sale of Interest in Gold Reserves and Resources 

In 2010, Carmen de Andacollo sold an interest in the gold reserves and resources of the Carmen de Andacollo Operation to Royal Gold. Under the agreement, Royal Gold is entitled to 75% of the payable gold produced until total cumulative production reaches 910,000 ounces of gold, and 50% thereafter. 

## 24. Segmented Information 

Based on the primary products we produce and our development projects, we have five reportable segments - copper, coal, zinc, energy and corporate - which is the way we report information to our Chief Executive Officer. The corporate segment includes all of our initiatives in other commodities, our corporate growth activities and groups that provide administrative, technical, financial and other support to all of our business units. Other operating expenses include general and administration costs, exploration, research and development, and other operating income (expense). Sales between segments are carried out at arm’s length prices.
