[1] The currency translation gain for the three and nine months ended September 30, 2016 is primarily driven by the modest weakening of the U.S. dollar (USD) against the European Euro (EUR) and the Brazilian real (BRL). The currency translation loss for the three months ended September 30, 2015 was driven by the strengthening of the USD against the BRL partially offset by the USD weakening against the EUR. The currency translation loss for the nine months ended September 30, 2015 was driven by the strengthening of the USD against both the BRL and the EURO.

[2] These amounts represent changes in accumulated other comprehensive loss excluding changes due to reclassifying amounts to the interim Consolidated Income Statements. See Notes 13 and 14 for additional information.

[3] These accumulated other comprehensive loss components are included in the computation of net periodic benefit cost of the company's pension and other long-term employee benefit plans. See Note 14 for additional information.
