[1] The increase over prior year is driven by the strengthening USD against primarily the Euro and Brazilian real, and changes in certain foreign entity's functional currency as described in Note 1.

[2] These amounts represent changes in accumulated other comprehensive loss excluding changes due to reclassifying amounts to the interim Consolidated Income Statements.

[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 13 for additional information.
