The eventual settlement of substantially all PERs estimated is expected to take place between 2022 and 2061.

The total PER has decreased in the fourth quarter of 2021 by $97 million primarily due to spending incurred during the quarter, combined with the divestment of our Lone Tree mine and changes in cost estimates at our Pascua-Lama, Lumwana and Buzwagi properties. For the year ended December 31, 2021, our PER balance decreased by $356 million primarily due to the divestment of our Lagunas Norte mine and spending incurred during the year. A 1% increase in the discount rate would result in a decrease in PER by $315 million and a 1% decrease in the discount rate would result in a decrease in PER by $nil (as the discount rate used was 0%), while holding the other assumptions constant.
