1: Revisions to estimated cash flows during the year ended December 31, 2016 and 2015 are primarily attributable to the acceleration in the estimated timing of abandonment of a large number of our producing properties resulting from decreases in commodity prices used in the calculation of the Company's reserves as of December 31, 2016 and 2015, respectively, which shortened the economic lives of these properties. For the year ended December 31, 2016, the increase was partially offset by decreases in the estimates of future costs required to plug and abandon wells in certain fields in the Central and Northern Rocky Mountains.
