Proved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that associated carrying costs may not be recoverable. The Company uses an income valuation technique, which converts future cash flows to a single present value amount, to measure the fair value of proved properties using a discount rate, price and cost forecasts, and certain reserve risk-adjustment factors, as selected by the Company’s management. The Company uses a discount rate that represents a current market-based weighted average cost of capital. The prices for oil and gas are forecast based on NYMEX strip pricing, adjusted for basis differentials, for the first five years, after which a flat terminal price is used for each commodity stream. The prices for NGLs are forecasted using Oil Price Information Service (“OPIS”) Mont Belvieu pricing, for as long as the market is actively trading, after which a flat terminal price is used. Future operating costs are also adjusted as deemed appropriate for these estimates. Certain undeveloped reserve estimates are also risk-adjusted given the risk to related projected cash flows due to performance and exploitation uncertainties.</span></div><div style="text-indent:36pt;margin-bottom:12pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%;">Other Property and Equipment.</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;"> Other property and equipment costs are evaluated for impairment and reduced to fair value when there is an indication the carrying costs may not be recoverable. To measure the fair value of other property and equipment, the Company uses an income valuation technique or market approach depending on the quality of information available to support management’s assumptions and the circumstances. The valuation includes consideration of the proved and unproved assets supported by the property and equipment, future cash flows associated with the assets, and fixed costs necessary to operate and maintain the assets.</span></div><div style="text-indent:36pt;margin-bottom:12pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;">No proved property impairment expense was recorded during the three months ended June 30, 2020. For the six months ended June 30, 2020, the Company recorded impairment expense of $956.7 million related to its South Texas proved oil and gas properties and related support facilities due to the decrease in commodity price forecasts at the end of the first quarter of 2020, specifically decreases in oil and NGL prices. The Company used a discount rate of 11 percent in its calculation of the present value of expected future cash flows based on the prevailing market-based weighed average cost of capital as of March 31, 2020. No proved property impairment expense was recorded during the three or six months ended June 30, 2019.</span></div>
