Discontinued Operations	5. Discontinued Operations In 2015, we completed the sale of Waterloo for approximately $14 million in cash, subject to certain post-closing adjustments. We recorded a pre-tax loss of $16.9 million as the result of this sale. Transaction and other sale-related costs were approximately $2.8 million. The estimated tax benefit on the sale was $26.5 million with the after-tax gain of $7.0 million recorded within discontinued operations. The estimated tax benefit resulted primarily from a tax loss in excess of the financial reporting loss as a result of prior period nondeductible asset impairments. Waterloo is presented as a discontinued operation in our financial statements beginning January 1, 2014 and through the date of sale in accordance with ASC 205 requirements. Prior to classifying Waterloo as a discontinued operation, it was reported in the Security segment. In the twelve months ended December 31, 2017, the loss on discontinued operations is primarily related to the prior sale of the Waterloo tool storage and Simonton window businesses.
