(1)       

Represents decommissioning and restoration provisions associated with the retirement of Property, Plant and Equipment and Exploration and Evaluation assets. The total undiscounted amount of estimated future cash flows required to settle the obligations at December 31, 2019 was approximately $12.9 billion (December 31, 2018 – $13.0 billion). A weighted average credit-adjusted risk-free interest rate of 3.30% was used to discount the provision recognized at December 31, 2019 (December 31, 2018 – 4.20%). The credit-adjusted risk-free interest rate used reflects the expected time frame of the provisions. Payments to settle the decommissioning and restoration provisions occur on an ongoing basis and will continue over the lives of the operating assets, which can exceed 50 years.

(2)       

Includes legal and environmental provisions.
