Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Risk Management | 14. Risk Management Certain of our business activities expose us to risks associated with unfavorable changes in the market price of natural gas, NGL and crude oil. We also have exposure to interest rate and foreign currency risk as a result of the issuance of our debt obligations. Pursuant to our management’s approved risk management policy, we use derivative contracts to hedge or reduce our exposure to some of these risks. Energy Commodity Price Risk Management As of December 31, 2023, we had the following outstanding commodity forward contracts to hedge our forecasted energy commodity purchases and sales:
| Net open position long/(short)
Derivatives designated as hedging contracts |  |
Crude oil fixed price | (16.9) |  | MMBbl
Natural gas fixed price | (61.0) |  | Bcf
Natural gas basis | (35.4) |  | Bcf
NGL fixed price | (0.6) |  | MMBbl
Derivatives not designated as hedging contracts |  |
Crude oil fixed price | (1.2) |  | MMBbl
Crude oil basis | (4.1) |  | MMBbl
Natural gas fixed price | (7.5) |  | Bcf
Natural gas basis | (101.6) |  | Bcf
NGL fixed price | (0.7) |  | MMBbl
As of December 31, 2023, the maximum length of time over which we have hedged, for accounting purposes, our exposure to the variability in future cash flows associated with energy commodity price risk is through December 2028. Interest Rate Risk Management We utilize interest rate derivatives to hedge our exposure to both changes in the fair value of our fixed rate debt instruments and variability in expected future cash flows attributable to variable interest rate payments. The following table summarizes our outstanding interest rate contracts as of December 31, 2023:
|  | Notional amount |  | Accounting treatment |  | Maximum term
|  | (In millions) |  |  |  |
Derivatives designated as hedging instruments |  |  |  |  |  |  |
Fixed-to-variable interest rate contracts(a)(b) |  | $ | 6,200 |  |  | Fair value hedge |  | March 2035
Treasury locks(c) |  | 1,000 |  |  | Cash flow hedge |  | March 2024
(a)The principal amount of hedged senior notes consisted of $1,450 million included in “Current portion of debt” and $4,750 million included in “Long-term debt” on our accompanying consolidated balance sheet. (b)During the year ended December 31, 2023, certain optional expedients as set forth in Topic 848 – Reference Rate Reform were elected on certain of these contracts to preserve fair value hedge accounting treatment. See Note 19 “Recent Accounting Pronouncements” for further information on Topic 848. (c)The treasury lock agreements were terminated on January 29, 2024 concurrently with the issuance of senior notes which closed on February 1, 2024 (see Note 9 “Debt”). Foreign Currency Risk Management We utilize foreign currency derivatives to hedge our exposure to variability in foreign exchange rates. The following table summarizes our outstanding foreign currency contracts as of December 31, 2023:
|  | Notional amount |  | Accounting treatment |  | Maximum term
|  | (In millions) |  |  |  |
Derivatives designated as hedging instruments |  |  |  |  |  |  |
EUR-to-USD cross currency swap contracts(a) |  | $ | 543 |  |  | Cash flow hedge |  | March 2027
(a)These swaps eliminate the foreign currency risk associated with our Euro-denominated debt. Impact of Derivative Contracts on Our Consolidated Financial Statements The following table summarizes the fair values of our derivative contracts included in our accompanying consolidated balance sheets:

The following two tables summarize the fair value measurements of our derivative contracts based on the three levels established by the ASC. The tables also identify the impact of derivative contracts which we have elected to present on our accompanying consolidated balance sheets on a gross basis that are eligible for netting under master netting agreements.

(a)Any cash collateral paid or received is reflected in this table, but only to the extent that it represents variation margins. Any amount associated with derivative prepayments or initial margins that are not influenced by the derivative asset or liability amounts or those that are determined solely on their volumetric notional amounts are excluded from this table. (b)Level 1 consists primarily of NYMEX natural gas futures. Level 2 consists primarily of OTC WTI swaps, NGL swaps and crude oil basis swaps. The following tables summarize the pre-tax impact of our derivative contracts in our accompanying consolidated statements of income and comprehensive income:

(a)We expect to reclassify an approximately $10 million loss associated with cash flow hedge price risk management activities included in our accumulated other comprehensive loss balance as of December 31, 2023 into earnings during the next twelve months (when the associated forecasted transactions are also expected to impact earnings); however, actual amounts reclassified into earnings could vary materially as a result of changes in market prices. (b)During the years ended December 31, 2023, 2022 and 2021, we recognized gains of none, $121 million and $41 million, respectively, associated with a write-down of hedged inventory. All other amounts reclassified were the result of the hedged forecasted transactions actually affecting earnings (i.e., when the forecasted sales and purchases actually occurred).

Total(a) |  |  |  | $ | 178 |  |  | $ | (74) |  |  | $ | (493) |
(a)The years ended December 31, 2023, 2022 and 2021 include approximate gains (losses) of $58 million, $(11) million and $(479) million, respectively, associated with natural gas, crude and NGL derivative contract settlements. Credit Risks In conjunction with certain derivative contracts, we are required to provide collateral to our counterparties, which may include posting letters of credit or placing cash in margin accounts. As of December 31, 2023 and 2022, we had no outstanding letters of credit supporting our commodity price risk management program. As of December 31, 2023 and 2022, we had cash margins of $63 million and $1 million, respectively, posted by our counterparties with us as collateral and reported within “Other current liabilities” on our accompanying consolidated balance sheets. The balance at December 31, 2023 represents the initial margin requirements of $22 million, offset by counterparty variation margin requirements of $85 million. We also use industry standard commercial agreements that allow for the netting of exposures associated with transactions executed under a single commercial agreement. Additionally, we generally utilize master netting agreements to offset credit exposure across multiple commercial agreements with a single counterparty. We also have agreements with certain counterparties to our derivative contracts that contain provisions requiring the posting of additional collateral upon a decrease in our credit rating. As of December 31, 2023, based on our current mark-to- market positions and posted collateral, we estimate that if our credit rating were downgraded one notch, we would not be required to post additional collateral. If we were downgraded two notches, we estimate that we would be required to post $54 million of additional collateral.
