As a result of the Chapter 11 Cases, we determined that a triggering event had occurred. As a result of our impairment analysis, $40.5 million of impairment on property, plant and equipment was recognized in the year ended December 31, 2017. The estimated fair value of the property, plant and equipment as of December 31, 2017 was determined based on an analysis of the value in-use and the value in-exchange of the property, plant and equipment. Upon determining these values, an economic obsolescence factor was applied to the value in-use to determine the amount of impairment to property, plant and equipment based upon Level 3 inputs. The $40.5 million impairment was allocated $10.2 million to land and improvements, $8.0 million to buildings and improvements, $21.4 million to machinery, equipment, furniture and fixtures, and $0.9 million to construction work in progress.
