PROPERTY AND EQUIPMENT
The major categories of property and equipment and related accumulated depletion, depreciation, amortization and impairment as of September 30, 2015 and December 31, 2014 are as follows:
Included in oil and natural gas properties at September 30, 2015 is the cumulative capitalization of $93.5 million in general and administrative costs incurred and capitalized to the full cost pool. General and administrative costs capitalized to the full cost pool represent management’s estimate of costs incurred directly related to exploration and development activities such as geological and other administrative costs associated with overseeing the exploration and development activities. All general and administrative costs not directly associated with exploration and development activities were charged to expense as they were incurred. Capitalized general and administrative costs were approximately $7.3 million and $20.8 million for the three and nine months ended September 30, 2015, respectively, and $5.9 million and $19.1 million for the three and nine months ended September 30, 2014, respectively.
The following table summarizes the Company’s non-producing properties excluded from amortization by area at September 30, 2015:
At December 31, 2014, approximately $1.5 billion of non-producing leasehold costs was not subject to amortization.
The Company evaluates the costs excluded from its amortization calculation at least annually. Subject to industry conditions and the level of the Company’s activities, the inclusion of most of the above referenced costs into the Company’s amortization calculation is expected to occur within three to five years.
The Company's oil and natural gas properties are subject to quarterly full cost ceiling tests. Under the ceiling test, capitalized costs, less accumulated amortization and related deferred income taxes, may not exceed an amount equal to the sum of the present value of estimated future net revenues less estimated future expenditures to be incurred in developing and producing the proved reserves based on internally prepared reserve reports, less any related income tax effects. Estimated future net revenues for the quarterly ceiling are calculated using the average of commodity prices on the first day of the month over the trailing 12-month period. At September 30, 2015, the net book value of the Company’s oil and gas properties, less related deferred income taxes, was above the calculated ceiling as a result of reduced commodity prices for the period leading up to September 30, 2015. As a result, the Company was required to record an impairment of its oil and gas properties under the full cost method of accounting in the amount of $594.8 million for the three and nine months ended September 30, 2015.
A reconciliation of the Company's asset retirement obligation for the nine months ended September 30, 2015 and 2014 is as follows:
