The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The net pre-tax exchange gains (losses) are recorded in other income, net and the related tax impact is recorded in provision for income taxes on the company's interim Consolidated Income Statements. Refer to Note 5 for discussion of the tax impacts related to this program. The $54 net exchange gain for the nine months ended September 30, 2015, includes a net $(35) pre-tax exchange loss associated with the devaluation of the Ukrainian hryvnia. The $44 net exchange gain for the nine months ended September 30, 2014, includes $(58), $(46) and $(14) exchange losses, associated with the devaluation of the Venezuela bolivar, Ukrainian hryvnia, and Argentinian peso, respectively
