(1) As a result of our sale of our 49% equity interest in Nadro, foreign currency translation net losses of $44 million were reclassified from AOCI to other income, within our condensed consolidated statement of operations. Such losses were previously considered in our impairment evaluation of the investment when we committed to a plan to sell the investment during the fourth quarter of 2013, and accordingly did not impact earnings for the second quarter and first six months of 2014.

(2) Pre-tax amount was reclassified into cost of sales and operating expenses in the condensed consolidated statements of operations. The related tax expense (benefit) was reclassified into income tax expense in the condensed consolidated statements of operations.
