We review unproved oil and gas properties for impairment based on our current exploration plans and proved oil and gas properties by comparing the expected undiscounted future cash flows at a producing field level to the unamortized capitalized cost of the asset. In third quarter 2015, we recognized $81,240,000 in non-cash impairment charges of which $65,382,000 is related to our proved oil and gas properties, primarily in North Dakota, Nebraska and Kansas and $15,858,000 is related to our unproved leasehold interests primarily in North Dakota. These non-cash impairment charges are a result of continued decline in oil prices and our current exploration plans. West Texas Intermediate (WTI) oil prices (the principal benchmark price for our oil sales), declined approximately 24 percent during third quarter 2015. Impairment charges are included in cost of oil and gas producing activities on our consolidated statements of income and comprehensive income. Third quarter 2015 non-cash impairment charges included $1,361,000 of write-down associated with certain producing properties that met the assets held for sale criteria. Carrying value of these assets was adjusted to fair value and $1,534,000 were reclassified from oil and gas properties to assets held for sale which is included in other assets on our consolidated balance sheet. Upon classification as held for sale, long-lived assets are no longer depreciated or depleted, and a measurement for impairment is performed to identify and expense any excess of carrying value over fair value less estimated costs to sell. In first nine months 2015, we recognized non-cash impairment charges of $36,768,000 on our unproved leasehold interests and $90,417,000 on our proved properties principally due to a significant decline in oil prices, drilling results, a change in our plans to develop acreage and increased likelihood that certain non-core oil and gas assets will be sold. Dry hole costs in first nine months 2015 were $9,952,000, which includes a $9,674,000 charge in second quarter 2015 primarily associated with an exploratory well in Oklahoma. In addition, in second quarter 2015 we expensed $917,000 of capitalized costs related to pre-drilling activities associated with non-core oil and gas properties in Oklahoma. In first nine months 2015, we recorded a net loss of ($1,320,000) on the sale of 27,662 net mineral acres leased from others and the disposition of 29 gross (5 net) producing oil and gas wells in Nebraska, Texas, Colorado, North Dakota and Oklahoma for total sales proceeds of $13,111,000.
