[1] During 2025, the Company revised its presentation of transportation, blending and feedstock costs, showing the expenses on a disaggregated basis. The comparative periods presented have been updated to reflect the revision (note 1).
[2] Depletion, depreciation and amortization expense for the year ended December 31, 2025 includes a $1,462 million (2024 – $160 million; 2023 – $436 million) non-cash recoverability charge for revisions to abandonment and decommissioning costs in the North Sea, a $269 million non-cash recoverability charge related to the decision to not pursue an extension of the Company's Production Sharing Contract ("PSC") for the Espoir field in Offshore Africa, and a $46 million non-cash derecognition of exploration and evaluation assets related to the decision to not pursue development of Kossipo in Offshore Africa (notes 5 and 6).
