^(a)

The decrease in net periodic benefit costs for the nine months ended September 29, 2013, compared to the nine months ended September 30, 2012, for our U.S. qualified plans was primarily driven by lower service cost resulting from the decision in 2012 to freeze the defined benefit plans in the U.S. and Puerto Rico, lower settlement activity and greater expected return on plan assets resulting from a higher plan asset base, partially offset by the curtailment gain in the second quarter of 2012 resulting from the decision to freeze the defined benefit plans in the U.S. and Puerto Rico. Also, the decrease in the discount rate resulted in lower interest costs, as well as an increase in the amounts amortized for actuarial losses.

^(b)

The increase in net periodic benefit costs for the nine months ended September 29, 2013, compared to the nine months ended September 30, 2012, for our U.S. supplemental (non-qualified) pension plans was primarily driven by higher settlement activity, an increase in the amounts amortized for actuarial losses resulting from the decrease in the discount rate and the curtailment gain in the second quarter of 2012 resulting from the decision to freeze the defined benefit plans in the U.S. and Puerto Rico, partially offset by special termination benefits in 2012.


^(c)	The increase in net periodic benefit costs for the nine months ended September 29, 2013, compared to the nine months ended September 30, 2012, for our international pension plans was primarily driven by an increase in the amounts amortized for actuarial losses resulting from decreases in discount rates and higher settlement activity.
