Energy Located in the Athabasca oil sands region of northeastern Alberta, our energy assets include a 20% interest in the  Fort Hills oil sands project and a 100% interest in the Frontier oil sands project. In addition, we hold a 50% interest  in various other oil sands leases in the exploration phase, including the Lease 421 Area. Our recoverable contingent  bitumen resources totalled 3.5 billion barrels at the end of 2012. These valuable long-term assets are located in  a politically stable jurisdiction and will be mined using conventional technologies that build upon our core skills in  large-scale truck and shovel operations. We recognize that there are concerns over the potential environmental effects of developing oil sands projects. As  such, we are researching methods to improve extraction and processing to enhance the sustainability of our projects.  We are proud to be one of the founding members of the Canadian Oil Sands Innovation Alliance (COSIA) and are  encouraged by the progress of the industry towards improving technology and production processes, reducing water  consumption, improving tailings management, and increasing land reclamation and revegetation. We are also developing renewable energy projects. We have a 30% interest in the Wintering Hills Wind Power Facility,  which completed its first full year of operation in 2012. The disclosure that follows includes references to contingent bitumen resource estimates. Further information  on these estimates, and the related risks and uncertainties, is set out in our most recent Annual Information Form,  which is available on our website at www.teck.com, or on the Canadian Securities Administrators website at  www.sedar.com (SEDAR) and under cover of Form 40-F on the EDGAR section of the Securities Exchange  Commission (SEC) website at www.sec.gov. There is no certainty that it will be commercially viable to produce  any portion of the contingent resources.  The Fort Hills oil sands project is located approximately 90 kilometres north of Fort McMurray in northern Alberta.  We hold a 20% interest in the Fort Hills Energy Limited Partnership (Fort Hills Partnership), which owns the Fort Hills  oil sands project, with 39.2% held by Total E&P Canada Ltd. (Total) and the remaining 40.8% held by the operator of  the project, Suncor Energy Inc. (Suncor). At December 31, 2012, our best estimate of our 20% share of the recoverable bitumen at Fort Hills is 662 million  barrels. To the end of 2012, approximately $3.3 billion has been spent on the Fort Hills project. Our share was $1.1 billion,  of which $122 million was spent in 2012. In connection with our ownership interest, we are committed to fund 27.5%  of the next $4.2 billion of project spending and our 20% pro rata share thereafter. Suncor has provided a forecast project spending estimate of approximately $1.05 billion for 2013, of which our share  should be $290 million, including our earn-in commitments.
