Asset Impairment Charges
7.    Asset Impairment Charges
In January 2017, we committed to a plan to sell Field ID, our cloud-based inspection and safety compliance software product line included in our Doors & Security segment. In accordance with FASB Accounting Standards Codification (“ASC”) 360, as a result of our decision to sell, during the first quarter of 2017 we recorded $3.2 million of 
pre-tax
 impairment charges to write down the long-lived assets included in this disposal group to fair value, based upon their estimated fair value less cost to sell. These charges consisted of approximately $3.0 million for definite-lived intangible assets and $0.2 million for fixed assets. We completed the sale of Field ID in April 2017.
