[1]	The unfavorable change in our U.S. qualified plans' projected benefit obligations funded status was largely driven by changes in interest rates and lower than expected asset returns, partially offset by plan contributions of $2.0 billion.
[2]	The U.S. supplemental (non-qualified) pension plans are not generally funded and these obligations, which are substantially greater than the annual cash outlay for these liabilities, are paid from cash generated from operations.
[3]	The favorable change in our international plans' projected benefit obligations funded status was largely driven by changes in actuarial assumptions, partially offset by the weakening of the U.S. dollar against the U.K. pound and euro. Outside the U.S., in general, we fund our defined benefit plans to the extent that tax or other incentives exist and we have accrued liabilities on our consolidated balance sheet to reflect those plans that are not fully funded.

- Definition

For defined benefit pension plans, the actuarial present value of benefits (whether vested or nonvested) attributed by the pension benefit formula to employee service rendered before a specified date and based on employee service and compensation (if applicable) before that date. The accumulated benefit obligation differs from the projected benefit obligation in that it includes no assumption about future compensation levels. For plans with flat-benefit or nonpay-related pension benefit formulas, the accumulated benefit obligation and the projected benefit obligation are the same.
