As part of this divestiture, the Company made a cash payment of $54 million to the buyer to fund future operational improvement initiatives. The Company recorded a pre-tax loss on divestiture, including transaction costs, of $95 million. The tax impact of the divestiture was income tax expense of $38 million due to the jurisdictional mix of gains and losses on the sale, which resulted in non-benefited losses in certain countries and taxable gains in other countries. There was no change in goodwill as a result of this transaction. In the three months ended June 30, 2014, the Company recorded a $25 million charge within loss from discontinued operations, net of tax on the consolidated statements of income related to the indemnification of certain costs associated with a divested business in 2004.
