In the first quarter of 2024, we recorded before-tax impairments totaling $163 million related to certain crude oil processing and logistics assets in California, of which $104 million was reported in our Refining segment and $59 million was reported in our Midstream segment.
These impairment charges are included within the “Impairments” line item on our consolidated statement of income. See Note 15—Fair Value Measurements, for additional information on the determination of fair value used to record these impairments.
