We recorded depreciation and depletion expense of $21.3 million and $22.6 million in the Statements of Unaudited Condensed Consolidated Operations for the three months ended MarchÌý31, 2018 and MarchÌý31, 2017, respectively.
As of MarchÌý31, 2018, based on the anticipated closure of the Asia Pacific Iron Ore operations we determined that we would not recover the value of certain long-lived assets at our Asia Pacific Iron Ore operations. As a result, we recorded an impairment of $2.6 million in Miscellaneous – net in the Statements of Unaudited Condensed Consolidated Operations.
