Pursuant to an agreement we entered into in December 2017, on January 26, 2018 we completed the sale of our Waste Management Segment to JFL-WCS Partners, LLC ("JFL Partners"), an entity sponsored by certain investment affiliates of J.F. Lehman & Company, for consideration consisting of the assumption of all of WCS' third-party indebtedness and other liabilities. We recognized a pre-tax gain of approximately $58 million primarily in the first quarter of 2018 on the transaction ($34.7 million, or $1.22 per diluted share, net of tax) because the carrying value of the liabilities of the business assumed by the purchaser exceeded the carrying value of the assets sold at the time of the sale in large part due to the previously-reported long-lived asset impairment of $170.6 million recognized in the second quarter of 2017. We recognized a pre-tax gain of $4.9 million ($4.3 million or $.15 per diluted share, net of tax) in the fourth quarter of 2020 related to proceeds received from JFL Partners in final settlement of an earn-out provision in the sale agreement. Our Waste Management Segment, which operated in the low-level radioactive, hazardous, toxic and other waste disposal industry historically struggled to generate sufficient recurring disposal volumes to generate positive operating results or cash flows. The sale enabled us to focus more effort on continuing to develop our remaining segments which we believe have greater opportunity for higher returns.

In accordance with GAAP, the Waste Management Segment has been reclassified as discontinued operations in our Consolidated Statements of Income. Also in accordance with GAAP, we have not reclassified our Consolidated Statement of Cash Flows to reflect the Waste Management Segment as discontinued operations.

Selected financial data for the operations of the disposed Waste Management Segment for the period prior to completing the sale is presented below.
