The Company determines fair value based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company's own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. The fair value input hierarchy level to which an asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety.

•Level 2 – quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g. interest rates) and inputs derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 – unobservable inputs for the asset or liability, typically reflecting management's estimate of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques, including discounted cash flow models.

(a)Includes $84 million and $328 million as of September 30, 2022 and December 31, 2021, respectively, of liabilities recorded in the fourth quarter of 2021 related to entering into equal and offsetting oil and gas commodity derivative trades that had the net effect of eliminating certain of the Company's 2022 derivative obligations.

Investment in affiliate. The Company elected the fair value option for measuring its equity method investment in ProPetro Holding Corp. ("ProPetro"). The fair value of the Company's investment in ProPetro common stock is determined using Level 1 inputs based on observable prices on a major exchange. See Note 11 and Note 13 for additional information.

Deferred compensation plan assets. The Company's deferred compensation plan assets include investments in equity and mutual fund securities that are actively traded on major exchanges. The fair value of these investments is determined using Level 1 inputs based on observable prices on major exchanges.

Short-term investment. In October 2021, the Company acquired 960 thousand shares of Laredo as partial consideration for its divestiture of certain acreage in western Glasscock County to Laredo. The shares were treated as an investment in equity securities measured at fair value. The fair value of the Company's investment in Laredo common stock was determined using Level 1 inputs based on observable prices on a major exchange, resulting in the fair value of the Laredo shares being based on

Commodity price derivatives. The Company's commodity price derivatives primarily represent oil and gas swap contracts, collar contracts, collar contracts with short puts, option contracts and basis swap contracts. The asset and liability measurements for the Company's commodity price derivative contracts are determined using Level 2 inputs. The Company utilizes discounted cash flow and option-pricing models for valuing its commodity price derivatives.

The liability values attributable to the Company's commodity price derivatives were determined based on inputs that include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) the implied rate of volatility inherent in the collar contracts and collar contracts with short puts, which is based on active and independent market-quoted volatility factors.

Conversion option derivatives. In May 2020, the Company issued $1.3 billion principal amount of convertible senior notes due 2025 (the "Convertible Notes"). Certain holders of the Convertible Notes exercised their conversion option during the nine months ended September 30, 2022. Per the terms of the notes indenture, the Company elected to settle the conversions in cash, with settlement occurring 25 trading days from the notice of conversion (the "Settlement Period"). The Company's election to settle an exercised conversion option in cash results in a forward contract during the Settlement Period that is accounted for as a derivative instrument not designated as a hedge. The change in fair value of the conversion option derivatives during the Settlement Periods is primarily determined based on Level 2 inputs related to the daily volumetric weighted average prices ("VWAP") of the Company's common stock during the Settlement Period. Conversion option derivative assets and liabilities recorded in the consolidated balance sheets were less than $1 million as of September 30, 2022. See Note 5, Note 7 and Note 17 for additional information.

Marketing derivatives. The Company's marketing derivatives reflect long-term marketing contracts whereby the Company agreed to purchase and simultaneously sell barrels of oil at an oil terminal in Midland, Texas. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland oil price and the price the Company receives for the oil volumes sold is a WASP that the non-affiliated counterparty receives for selling oil through a Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Based on the form of the long-term marketing contracts, the Company accounts for the contracts as derivative instruments not designated as hedges. The asset and liability measurements for the long-term marketing contracts are determined using both Level 2 and 3 inputs. The Company utilizes a discounted cash flow model for valuing the marketing derivatives.

The asset and liability values attributable to the Company's marketing derivatives that are determined based on Level 2 inputs include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) stated contractual rates. The Level 3 inputs attributable to the Company's marketing derivatives include the historical monthly differential between Brent oil prices and the corresponding WASP of the counterparty to the marketing derivatives ("WASP Differential Deduction") and, to a lesser extent, an estimated annual cost inflation rate. The average WASP Differential Deduction used in the fair value determination as of September 30, 2022 and 2021 was $1.63 per barrel and $2.07 per barrel, respectively. The WASP Differential Deduction and the estimated annual cost inflation rate reflects management's best estimate of future results utilizing historical performance, but these estimates are not observable inputs by a market participant and contain a high degree of uncertainty. The Company experiences mark-to-market fluctuations in the fair value of its marketing derivatives based on changes in the WASP Differential Deduction if it deviates from historical levels. For example, a 10 percent increase or decrease in the WASP Differential Deduction would impact the fair value of the Company's marketing derivatives recorded by approximately $28 million as of September 30, 2022.

Assets and liabilities measured at fair value on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets and liabilities can include inventories, proved and unproved oil and gas properties, assets acquired and liabilities assumed in business combinations, goodwill and other long-lived assets that are written down to fair value when they are determined to be impaired or held for sale.

(b)Represents funds in escrow for use in future deficiency fee payments associated with the Company's 2019 sale of its Eagle Ford assets and other remaining assets in South Texas (the "South Texas Divestiture"). Any remaining balance after the payment of the deficiency fees will revert to the Company on March 31, 2023. See Note 10 for additional information.

(c)The carrying value as of September 30, 2022, represents commercial paper investments that are carried at amortized cost and classified as held-to-maturity as the Company has the intent and ability to hold them until they mature. Commercial paper is included in cash and cash equivalents if it has maturity dates that are less than 90 days at the date of purchase; otherwise, investments are reflected in short-term investments in the consolidated balance sheets based on their maturity dates. Fair value for the Company's commercial paper investments is determined using Level 2 inputs.

The Company has other financial instruments consisting primarily of receivables, payables, prepaid expenses and other current assets and liabilities that approximate fair value due to the nature of the instrument and their relatively short maturities. Non-financial assets and liabilities initially measured at fair value include assets acquired and liabilities assumed in business combinations, goodwill and asset retirement obligations.
