Risk-management Activities - We are sensitive to changes in the prices of natural gas, NGLs, Refined Products and crude oil, principally as a result of contractual terms under which these commodities are processed, purchased and sold. We are also subject to the risk of interest-rate fluctuation in the normal course of business. We use physical-forward purchases and sales and financial derivatives to secure a certain price for a portion of our natural gas, NGLs, Refined Products, condensate and crude oil purchases and sales; to reduce our exposure to commodity price and interest-rate fluctuations; and to achieve more predictable cash flows. Additionally, we may use physical-forward purchases and financial derivatives to reduce commodity price risk associated with power and natural gas used to operate our facilities. We follow established policies and procedures to assess risk and approve, monitor and report our risk-management activities. We have not used these instruments for trading purposes.

Commodity price risk - Commodity price risk refers to the risk of loss in cash flows and future earnings arising from adverse changes in the price of natural gas, NGLs, Refined Products and crude oil. We may use commodity derivative instruments to reduce the near-term commodity price risk associated with a portion of our forecasted purchases and sales of commodities. Our exposure to commodity price risk is consistent with that discussed in our Annual Report.

Interest-rate risk - We may manage interest-rate risk through the use of fixed-rate debt, floating-rate debt, Treasury locks and interest-rate swaps. At March 31, 2026, and December 31, 2025, we hadno outstanding interest-rate derivative instruments.

Fair Values of Derivative Instruments -The following table sets forth the fair values of our derivative instruments presented on a gross basis as of the dates indicated:

(a) - Derivative assets and liabilities are presented in our Consolidated Balance Sheets on a net basis when a legally enforceable master-netting arrangement exists between the counterparty to a derivative contract and us.

(b) - At March 31, 2026, our derivative net liability positions under master-netting arrangements for financial commodity contracts were offset by cash collateral of $287 million.

Notional Quantities for Derivative Instruments -The following table sets forth the notional quantities for our derivative instruments, consisting of futures and swaps, held as of the dates indicated:

Cash Flow Hedges - At March 31, 2026, the accumulated other comprehensive income (loss) relating to risk-management assets and liabilities, net of taxes, was $(220) million, which included unrealized losses of $(198) million, net of tax, related to commodity derivative instruments that we expect to be reclassified into earnings during the next 12 months.

For the three months ended March 31, 2026, the unrealized change in fair value of cash flow hedges in other comprehensive income (loss) related to commodity contracts was $(394) million and the effect of cash flow hedges on net income was not material.

Credit Risk - We monitor the creditworthiness of our counterparties and compliance with policies and limits established by our Risk Oversight and Strategy Committee. We maintain credit policies with regard to our counterparties that we believe minimize credit risk. Our policies and related credit risk are consistent with those discussed in our Annual Report.
