⁽¹⁾ Represents scheduled future maturities of our consolidated debt principal obligations. For information regarding our consolidated debt obligations, see Item 8. Financial Statements and Supplementary Data, under Note 17. Debt.

⁽²⁾ Estimated cash payments for interest exclude adjustments for derivative agreements and cash payments for interest on variable-rate debt. We borrow and repay at varying amounts and interest rates. For more information on our debt obligations, see Item 8. Financial Statements and Supplementary Data, under Note 17. Debt.

⁽³⁾ Represents commitments to purchase materials, primarily pipe from third-party suppliers in connection with our growth projects.

⁽⁴⁾ Represents commitments to purchase power in connection with our Liquids segment. We included certain power commitments with obligations that are dependent on variable components. For these commitments, we only included the determinable portion of our commitment based on the contracted usage requirement and the current applicable contract rate.

⁽⁵⁾ Represents long-term product purchase obligations with several third-party suppliers to acquire natural gas and NGLs at the approximate market value at the time of delivery. Also represents commitments to purchase drag reducing agents. 

⁽⁶⁾ Represents the minimum payment amounts for contracts for firm transportation and storage capacity we have reserved on third-party pipelines and storage facilities.

⁽⁷⁾ Represents the minimum payment amounts from contracts for firm fractionation of our NGL supply that we reserve at third party fractionation facilities.

⁽⁸⁾ Includes noncurrent portion of capital leases and deferred credits. We are unable to estimate deferred income taxes (see Note 22. Income Taxes) since cash payments for income taxes are determined primarily by taxable income for each discrete fiscal year. We are also unable to estimate asset retirement obligations (see Note 18. Asset Retirement Obligations), environmental liabilities (see Note 25. Commitments and Contingencies) and hedges payable (see Note 21. Derivative Financial Instruments and Hedging Activities) due to the uncertainty as to the amount and, or, timing of when cash payments will be required.
