The amortization of pension and postretirement benefit components is included in the computation of net periodic benefit cost. For more information, see "Note 19: Retirement Benefit Plans." 
 
We estimate that we will reclassify approximately $202 million (before taxes) of net derivative losses included in accumulated other comprehensive income (loss) into earnings within the next 12 months.
 
During the second quarter of 2017, we reclassified $507 million (before taxes) of currency translation adjustment losses included in accumulated other comprehensive income (loss) into earnings as a result of our divestiture of ISecG. For more information, see "Note 11: Acquisitions and Divestitures."
