The eventual settlement of substantially all PERs estimated is expected to take place between 2023 and 2062. The total PER has increased in the fourth quarter of 2022 by $126 million primarily due to changes in cost estimates at our Cortez, Carlin and Pascua-Lama properties, combined with a decrease in the discount rate. For the year ended December 31, 2022, our PER balance decreased by $521 million primarily due to an increase in the discount rate and spending incurred during the year, partially offset by the changes in cost estimates described above. A 1% increase in the discount rate would result in a decrease in the PER by $219 million and a 1% decrease in the discount rate would result in an increase in the PER by $266 million, while holding the other assumptions constant.
