The eventual settlement of substantially all PERs estimated is expected to take place between 2020 and 2059. The total PER has decreased in the fourth quarter of 2019 by $511 million primarily due to changes in cost estimates at our Pascua-Lama, Carlin, Golden Sunlight and Cortez properties, combined with the divestment of Kalgoorlie. For the year ended December 31, 2019, our PER balance increased by $241 million primarily due to the contribution of Newmont’s assets to Nevada Gold Mines on July 1, 2019, the acquisition of Randgold on January 1, 2019, and a decrease in the discount rate. These were partially offset by changes in cost estimates primarily at our Pascua-Lama, Pierina, Golden Sunlight, Lagunas Note and Pueblo Viejo properties, combined with the divestment of Kalgoorlie. A 1% increase in the discount rate would result in a decrease in PER by $357 million and a 1% decrease in the discount rate would result in an increase in PER by $207 million, while holding the other assumptions constant.
