(2) Purchase obligations are enforceable and legally binding obligations which primarily consist of raw material and energy-related take-or-pay contracts.

(3) Capital expenditure obligations primarily reflect amounts associated with our capital expansion activities.

(4) Total debt above is stated at maturity value, and excludes interest rate swap gains/losses and bond discounts.

(5) The estimate of interest payments assumes interest is paid through the date of maturity or expiration of the related debt, based upon stated rates in the respective debt instruments.

(6) At December 31, 2017, $54 million was included on our balance sheet related to uncertain tax positions.  Of this amount, we are unable to estimate when any of that amount will become payable.
