On October 31, 2018, we completed the sale of the Specialty Papers business on a cash free and debt free basis to Pixelle Specialty Solutions LLC, an affiliate of Lindsay Goldberg (the “Purchaser”) for $360 million. The sale of the business was in connection with the strategic focus on our more growth oriented Composite Fibers and Airlaid Materials. Cash proceeds from the sale were approximately $323 million reflecting estimated purchase price adjustments as of the closing date and the assumption by the Purchaser of approximately $38 million in retiree healthcare liabilities. In addition, the Purchaser assumed approximately $210 million of pension liabilities relating to Specialty Papers’ employees and received approximately $274 million of related assets from the Company’s qualified pension plan. We recognized a $144.1 million pre-tax loss, presented below as an “Impairment charge” for the amount by which Specialty Papers’ carrying value exceeded net proceeds from the sale.

In connection with the sale of Specialty Papers, we entered into a Transition Services Agreement with Purchaser pursuant to which we agreed to provide various back-office and information technology support until the business is fully separated from us, which was completed in the third quarter of 2019.

The amounts presented above are derived from the segment reporting for Specialty Papers adjusted to include certain retirement benefit costs and to exclude corporate shared services costs which are required to remain in continuing operations. Interest expense was allocated to discontinued operations based on borrowings under the revolving credit facility required to be repaid with proceeds from the sale of Specialty Papers. The amount set forth above in 2020 under the caption “Selling, general and administrative expenses,” primarily represents the settlement of a sales and use tax audit. The amounts in 2018 under the caption “Other, net” include the recognition of a $54.0 million, pre-tax, curtailment and settlement charge for pension and other post-employment benefits related to the transfer and discontinuance of future service of Specialty Papers’ employees.
