[1] The increase in currency translation adjustment gains over prior year for the three months ended March 31, 2016 is primarily driven by the modest weakening of the U.S. dollar (USD) against the European Euro and Brazilian real. The increase in currency translation adjustment losses over prior year for the three months ended March 31, 2015 is primarily driven by the strengthening USD against the European Euro and Brazilian real.

[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] The unrealized loss on securities during the three months ended March 31, 2016 is due to the re-measurement of USD denominated marketable securities held by certain foreign entities at March 31, 2016 with a corresponding offset to cumulative translation adjustment.

[4] 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.
