Pension settlement charges of $101 million were recognized in the second quarter of 2013 after determining that the annual lump sum payments will exceed the annual interest and service costs for certain pension plans, including the primary U.S. pension plan. The charge included the acceleration of a portion of unrecognized actuarial losses. The applicable pension benefit obligation and pension plan assets were remeasured as of June 30, 2013 resulting in a decrease in pension liabilities and a corresponding credit to other comprehensive income of $935 million ($605 million net of taxes). The weighted average discount rate assumed in remeasuring the pension benefit obligations was 4.5%.

Contributions to the U.S. pension plans are expected to approximate $185 million during 2013, of which $170 million was contributed in the six months ended June 30, 2013. Contributions to the international plans are expected to range from $60 million to $70 million in 2013, of which $46 million was contributed in the six months ended June 30, 2013.

The expense attributed to defined contribution plans in the U.S. was $43 million and $48 million for the three months ended June 30, 2013 and 2012, respectively and $90 million and $96 million for the six months ended June 30, 2013 and 2012, respectively.
