Total depreciation, depletion and amortization expense on property, plant and equipment was $24.8 million, $20.9 million and $15.2 million during 2014, 2013, and 2012, respectively.

NACoal's long-lived asset evaluation during 2014 resulted in the Company recording a non-cash, impairment charge with respect to its Reed Minerals mining operations asset group of $105.1 million recorded on the line Reed Minerals long-lived asset impairment charge in the Consolidated Statements of Operations, of which $99.4 million was for Reed Minerals' Property, Plant and Equipment. The fair value of the asset group was calculated using the combination of a market and income approach and reduced the carrying value of coal land and real estate to $7.2 million and other property, plant and equipment to $37.1 million. See Note 10 for further discussion of this nonrecurring fair value measurement.

KC's long-lived asset evaluations during 2014, 2013 and 2012 resulted in the Company recording an impairment charge of $0.9 million, $1.1 million and $0.7 million, respectively, in depreciation expense for leasehold improvements and furniture and fixtures as projected future cash flows were not sufficient to recover the net carrying value of these assets. See Note 10 for further discussion of these nonrecurring fair value measurements.

Proven and probable coal reserves, excluding the Unconsolidated Mines, approximated 1.0 billion tons (unaudited) at December 31, 2014 and 1.2 billion tons (unaudited) at December 31, 2013. These tons are reported on an "as received by the customer basis" and are the equivalent of “demonstrated reserves” under the coal resource classification system of the U.S. Geological Survey. Generally, these reserves would be commercially mineable at year-end prices and cost levels, using current technology and mining practices.
