[1] Represents reclassifications from Accumulated other comprehensive income (loss) due to the change in accounting for the Company’s Venezuelan operations. Cumulative translation, net actuarial gain (loss) and unrealized gains (losses) on available-for-sale securities were reclassified into the Charge for Venezuela accounting change on the Consolidated Statement of Income. See Note 14, Venezuela for additional details.

[2] These components of Other comprehensive income (loss) are included in the computation of total pension cost. See Note 10, Retirement Plans and Other Retiree Benefits for additional details.

[3] For the year ended December 31, 2015, these amounts included pretax net losses of $50 related to the remeasurement of the bolivar-denominated fixed interest rate bonds and the devaluation-protected bonds in Venezuela. For the year ended December 31, 2014, these amounts included pretax losses of $324 related to the remeasurement of the bolivar-denominated fixed interest rate bonds and the devaluation-protected bonds in Venezuela. For the year ended December 31, 2013, these amounts included pretax losses of $133 related only to the remeasurement of the bolivar-denominated fixed interest rate bonds in Venezuela as a result of the devaluation in the first quarter of 2013. No remeasurement charge was required on the devaluation-protected bonds in the first quarter of 2013 since the official exchange rate changed from 4.30 to 6.30 bolivares per dollar and the devaluation-protected bonds revalued to the official exchange rate. See Note 7, Fair Value Measurements and Financial Instruments for additional details
