[1] The increase in currency translation adjustment losses over prior year for the nine months ended September 30, 2015 is driven by the strengthening USD against primarily the Euro and Brazilian real. The change in both periods is also due to 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] See Note 13 for discussion of the re-measurement of the principal U.S. pension plan and other long-term employee benefit plans as a result of the Performance Chemicals separation.

[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 13 for additional information.
