Mine Closure and Asset Impairment Costs
 
In response to decreasing demand for thermal coal, the Company made the decision in the second quarter of 2012 to close four thermal coal mining complexes and to temporarily idle a fifth complex, all acquired with ICG. The company also curtailed production at other Appalachia mines.  These actions resulted in a total workforce reduction of approximately 750 positions. The Company will incur customary annual maintenance costs related to these properties in the future.  The terms of customer contracts will be fulfilled by other operations.
 
The following costs are reflected in the line “Mine closure and asset impairment costs” on the consolidated statements of operations for the year ended December 31, 2012:
 
Parts and supplies inventory writedown
$
2,598

Impairment of property, plant and equipment
95,641

Impairment of coal properties and deferred development costs
403,279

Royalty obligations
11,546

Employee termination benefits
12,274

Pension, postretirement and occupational disease curtailment gain, net (see notes 17 and 18)
(1,770
)
 
$
523,568



The Company determined that assets of the closed operations with a net book value of $51 million could be redeployed to other operations. The remainder of the assets were determined to be completely impaired, based on an analysis of the marketability of thermal coal properties in the current market environment.
 
The majority of the employee termination benefits were paid in the third quarter of 2012.  The royalty obligations represent minimum payments on various leases and will be paid over the remaining term of the leases, through 2016.
 
The $7.3 million in asset impairment costs for the year ended December 31, 2011 related to a preparation plant and loadout of an acquired ICG mining operation that would not be used in ongoing operations.
