Fair Value Measurements |
NOTE 6 - FAIR VALUE MEASUREMENTS
Occidental has categorized its assets and liabilities that are measured at fair value in a three-level fair value hierarchy, based on the inputs to the valuation techniques: Level 1 — using quoted prices in active markets for the assets or liabilities; Level 2 — using observable inputs other than quoted prices for the assets or liabilities; and Level 3 — using unobservable inputs. Transfers between levels, if any, are recognized at the end of each reporting period. FAIR VALUES - RECURRING In January 2012, Occidental entered into a long-term contract to purchase carbon dioxide (CO 2). This contract contains a price adjustment clause that is linked to changes in NYMEX oil prices. Occidental determined that the portion of this contract linked to NYMEX oil prices is not clearly and closely related to the host contract, and Occidental therefore bifurcated this embedded pricing feature from its host contract and accounts for it at fair value in the consolidated financial statements. The following tables provide fair value measurement information for embedded derivatives that are measured on a recurring basis:

FAIR VALUES - NONRECURRING 2021: For the three and six months ended June 30, 2021, Occidental recorded pre-tax impairments of $21 million and $156 million, respectively, related to non-core onshore and offshore domestic undeveloped leases that either expired or were set to expire in the near-term, where Occidental had no plans to pursue exploration activities. 2020: As a result of the expected prolonged period of lower commodity prices brought on by the COVID-19 pandemic’s impact on oil demand, Occidental tested substantially all of its oil and gas assets for impairment during the second quarter of 2020. Occidental recognized total pre-tax impairments to its oil and gas proved and unproved properties of $8.6 billion, of which $6.4 billion was included in oil and gas segment results and $2.2 billion ($1.4 billion net of tax) related to Ghana was included in discontinued operations for the three months ended June 30, 2020. For the three months ended June 30, 2020, Occidental recorded proved property pre-tax impairments of $1.2 billion primarily related to certain assets for its domestic onshore and Gulf of Mexico assets and $0.9 billion to remeasure the Algeria oil and gas proved properties to their fair value. The fair value of the proved properties was measured based on the income approach. Also during the three months ended June 30, 2020, $4.3 billion of unproved property pre-tax impairments were recorded primarily related to domestic onshore unproved acreage. The fair value of this acreage was measured based on a market approach using an implied acreage valuation derived from domestic onshore market participants excluding the fair value assigned to proved properties. Income approaches are considered Level 3 fair value estimates and include significant assumptions of future production and timing of production, commodity price assumptions, and operating and capital cost estimates, discounted using a 10% weighted average cost of capital. Taxes were based on current statutory rates. Future production and timing of production is based on internal reserves estimates and internal economic models for a specific oil and gas asset. Internal reserve estimates consisted of proved reserves and risk adjusted unproved reserves based on reserve category. Price assumptions were based on a combination of market information and published industry resources adjusted for historical differentials. Price assumptions ranged from approximately $40 per Bbl of oil in 2020 increasing to approximately $70 per Bbl of oil in 2034, with an unweighted arithmetic average price of $59.17 and $62.42 for WTI and Brent indexed assets for the 15-year period, respectively. Natural gas prices ranged from approximately $2.00 per Mcf in 2020 to approximately $3.60 per Mcf in 2034, with an unweighted arithmetic average price of $3.13 for NYMEX based assets for the 15-year period. Both oil and natural gas commodity prices were held flat after 2034 and were adjusted for location and quality differentials. Operating and capital cost estimates were based on current observable costs and were further escalated 1% in every period where commodity prices exceeded $50 per Bbl and 2% in every period where commodity prices exceeded $60 per Bbl. The weighted average cost of capital is calculated based on industry peers and approximates the cost of capital an external market participant would expect to obtain. In the first quarter of 2020, Occidental's oil and gas segment recognized pre-tax impairment and related charges of $581 million primarily related to both proved and unproved oil and gas properties and a lower of cost or net realizable value adjustment for crude inventory. Occidental recorded proved property impairments of $293 million related to certain international assets and the Gulf of Mexico. Occidental recorded unproved property impairments of $241 million primarily related to domestic onshore undeveloped leases and offshore Gulf of Mexico where Occidental no longer intends to pursue exploration, appraisal or development activities primarily due to the reduction in near-term capital plans.
