Asset Impairment Charges [Abstract]
Asset Impairment	4.ASSET IMPAIRMENT During the second quarter of 2020, in connection with an assessment of potential impairment of indefinite lived intangible assets, we recorded $0.9 million of non-cash asset impairment charge related to a trade name intangible asset acquired in connection with our Composite Fibers segment’s 2013 Dresden acquisition. The charge was due to a change in the estimated fair value of the trade name, primarily driven by lower forecasted wallcover revenues associated with economic instability in Russia and Ukraine and incremental impacts from the COVID-19 pandemic on this business. The charge is recorded in the accompanying condensed consolidated statements of income under the caption “Selling, general and administrative expenses.” The fair value of the asset was estimated using a discounted cash flow model, Level 3 fair value classification.
