              For the U.S. Qualified plan, the $1.0 billion voluntary contribution was paid in January 2015.[2]
              The unfavorable change in the funded status of our U.S. qualified plans is primarily due to (i) a decrease in the discount rate (reflecting lower interest rates) and (ii) a change in mortality assumptions (reflecting a longer life expectancy for plan participants), which more than offset (iii) a gain on plan assets.[3]
              Our U.S. supplemental (non-qualified) plans are generally not funded and these obligations, which are substantially greater than the annual cash outlay for these liabilities, will be paid from cash generated from operations.[4]
