[1] SLB recorded an adjustment of $54 million to write-up the acquired inventory to its estimated fair value. SLB’s Cost of sales will reflect this increased valuation as the acquired inventory is sold. $11 million of this adjustment was expensed as of December 31, 2023. See Note 3 – Charges and Credits.

[2] The goodwill recognized is primarily attributable to intangible assets that do not qualify for separate recognition as well as expected synergies from combining the subsea operations of SLB and Aker. None of the goodwill is deductible for income tax purposes
