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

[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.
