4. Asset Impairment

During 2019, the Company sold two buildings, which had previously been held for sale, for total net proceeds of $7.4 million. These buildings were in the Material Handling Segment. When a facility meets held for sale classification criteria, it is also evaluated for impairment by comparing its carrying value to its estimated fair value less estimated costs to sell. Estimated fair value of these buildings was based on third party offers, which are Level 2 inputs. Impairment charges of $0.9 million were recorded during the year ended December 31, 2019 in connection with a building meeting the held for sale criteria.
