The fiber plant produced approximately 100,000 tons of various slag wool fiber products annually. The closure resulted in the Company recording a restructuring and impairment charge of $3.6 million, of which $2.2 million related to the impairment of property, plant and equipment and $1.4 million related to severance and other obligations. In addition, Walter Coke recorded a charge of $0.9 million included in cost of sales in the 2009 statement of operations related to inventory write-downs. Approximately $0.1 million of cash was used in 2009 for the severance and other obligations, with the remainder expected to be expended in 2010. The property, plant and equipment of the fiber plant was written down to fair value of $0.2 million, which was estimated using comparable transactions of similar assets, less the cost to dispose of the assets.

A significant portion of the purchase price was allocated to the mineral interests, valued at $44.0 million. The initial value assigned to the mineral interests was determined using a discounted cash flow approach incorporating market-based assumptions when available. One of the significant assumptions used to determine the discounted cash flows associated with the minerals was the market price of similar coals at the date of acquisition and the future market pricing forecasts that existed as of that date. Subsequent to September 2, 2008, the market price and future forecasted market prices for similar coals dropped significantly. As such, the Company performed an impairment test of the mineral interests. The results of the impairment test indicated that there was an asset impairment and, as a result, the Company recorded a $32.4 million impairment charge in the 2008 fourth quarter.</td></tr></table> NOTE 4Restructuring and Impairments         Walter Coke    In December 2009, the Company false false Description of restructuring activities including exit and disposal activities, which should include facts and circumstances leading to the plan, the expected plan completion date, the major types of costs associated with the plan activities, total expected costs, the accrual balance at the end of the period, and the periods over which the remaining accrual will be settled.
