[1] Reclassified to Total Net Periodic Benefit Cost - refer to Note 13 - Employee Benefit Plans for additional information.

[2] The net actuarial loss (gain) for U.S. Plans primarily reflects (i) the remeasurement of our primary U.S. pension plans as a result of the payment of periodic settlements; and (ii) adjustments for the actuarial valuation results based on January 1st plan census data.

[3] Amounts represent the pre-tax effect included within Other comprehensive loss. Refer to Note 15 - Other Comprehensive (Loss) Income for related tax effects and the after-tax amounts.

[4] These full year estimates are based on current expectations that we will make additional 2016 cash contributions of $34 ($5 U.S. and $29 Non-U.S) to our defined benefit pension plans and $19 to our retiree health benefit plans.
