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.

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 asset and 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, collar contracts with short puts and option contracts, which is based on active and independent market-quoted volatility factors.

Marketing derivatives. Under the contract terms of the marketing derivatives, the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that ends on December 31, 2026. 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 weighted average sales price ("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 marketing contracts, the Company determined that the marketing contracts should be accounted for as derivative instruments not designated as hedges.

The asset and liability values attributable to the Company's marketing derivative were determined based on Level 2 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) 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 December 31, 2021 and 2020 was $2.19 per barrel and $1.91 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 could experience significant 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 $20 million as of December 31, 2021.

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.

Investment in affiliate and short-term investment. The Company elected the fair value option for measuring its equity method investment in ProPetro. The Laredo common stock held by the Company is treated as an investment in equity securities measured at fair value. The fair value of the Company's investments in ProPetro and Laredo common stock are determined using Level 1 inputs based on observable prices on a major exchange. See Note 3, Note 12 and Note 15 for additional information.

Contingent consideration. Per the terms of the South Texas Divestiture, the Company was entitled to receive contingent consideration based on future annual oil and NGL prices during each of the five years from 2020 to 2024. The Company revalued the contingent consideration using an option pricing model each reporting period prior to the settlement of the contingent consideration in July 2020, at which time, the Company received cash proceeds of $49 million from the buyer to fully satisfy the contingent consideration. The Company recorded a noncash loss of $42 million to interest and other income during the year ended December 31, 2020 associated with the settlement. During 2019, the Company recorded a noncash loss of $45 million to interest and other income associated with adjusting the contingent consideration to fair value. The fair value of the contingent consideration was determined using Level 2 inputs based on an option pricing model using quoted future commodity prices from active markets, implied volatility factors and counterparty credit risk assessments. See Note 3 and Note 5 and Note 15 for additional information.

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.

Parsley Acquisition and DoublePoint Acquisition. Both the Parsley Acquisition and DoublePoint Acquisition were accounted for using the acquisition method under ASC Topic 805, "Business Combinations", which requires all assets acquired and liabilities assumed in the acquisitions to be recorded at fair values at the acquisition date of each transaction. Oil and gas properties were valued based on income and market based approaches utilizing Level 3 inputs, including internally generated development and production profiles and price and cost assumptions. Debt assumed in the acquisitions was valued based on Level 2 inputs that included using observable market prices to determine fair value. Net derivative liabilities assumed in the acquisitions were valued based on Level 2 inputs similar to the Company's other commodity price derivatives. See Note 3 for additional information.

South Texas Divestiture. The Company recorded a deficiency fee obligation and related deficiency fee receivable in conjunction with the South Texas Divestiture. The fair value of the deficiency fee obligation and deficiency fee receivable was determined using Level 3 inputs based on a probability-weighted forecast that considers historical results, market conditions and various development plans to arrive at the estimated present value of the deficiency payments and corresponding receipts. Changes to the Company's forecasted deficiency fee obligation and estimated deficiency fee receivable are recorded in other

expense in the consolidated statements of operations. For the year ended December 31, 2021, the Company recorded a decrease in the deficiency fee obligation of $3 million and an increase to the deficiency fee receivable of $7 million. For the year ended December 31, 2020, the Company recorded an increase in the deficiency fee obligation of $84 million and an increase to the deficiency fee receivable of $4 million. The Company will not increase the estimated deficiency fee receivable associated with 2022 forecasted deficiencies until they are realizable. The present value of the future cash payments and expected cash receipts were determined using a 3.6 percent and 3.2 percent discount rate, respectively, based on the estimated timing of future payments and receipts and the Company's counterparty credit risk assessments. See Note 3, Note 11 and Note 16 for additional information.

Other assets. During the year ended December 31, 2019, the Company impaired the remaining $13 million of inventory and other property and equipment related to the decommissioning of the Company's Brady, Texas sand mine, as these assets had no remaining future economic value. In addition, the Company recognized a $16 million impairment charge related to pressure pumping assets that had no future benefit to the Company. See Note 16 for additional information.

Proved oil and gas properties. The Company performs assessments of its proved oil and gas properties, which are accounted for under the successful efforts method of accounting, whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future cash flows, including cash flows from the Company's water services business that are used in the development of the assets, is less than the carrying amount of the assets, including the carrying value of the water services business. In these circumstances, the Company recognizes an impairment charge for the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets.

Based on management's commodity price outlooks as of December 31, 2021, which represent longer-term commodity price outlooks that are developed based on third party future commodity price estimates as of a measurement date ("Management's Price Outlooks"), the Company determined events and circumstances did not indicate that the carrying value of the Company's proved properties were not recoverable.

Unproved oil and gas properties. Unproved oil and gas properties are periodically assessed for impairment on a project-by-project basis. These impairment assessments are affected by the results of exploration activities, commodity price outlooks, planned future property sales or expiration of all or a portion of such projects. If the Company's assessment determines that a project is not expected to be developed or is unlikely to recover its costs, the Company will recognize an impairment charge at that time. Impairment charges for unproved oil and gas properties are recorded in exploration and abandonments in the consolidated statements of operations. During 2021, 2020 and 2019, the Company recorded $4 million, $11 million and $4 million, respectively, to exploration and abandonments in the consolidated statements of operations.

Goodwill. Goodwill is assessed for impairment whenever it is more likely than not that events or circumstances indicate the carrying value of a reporting unit exceeds its fair value, but no less often than annually. An impairment charge is recorded for the amount by which the carrying amount exceeds the fair value of a reporting unit in the period it is determined to be impaired.

The Company has other financial instruments consisting primarily of receivables, payables 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.
