actions may be filed in the future. Based on information currently known, the amount of any potential loss attributable to
M-I SWACO with respect to potential liabilities related to the incident would not be material to Schlumberger’s
consolidated financial position.
Schlumberger and its subsidiaries are party to various other legal proceedings from time to time. A liability is accrued
when a loss is both probable and can be reasonably estimated. Management believes that the probability of a material
loss is remote and, as such, that any liability that might ensue would not be material in relation to Schlumberger’s
consolidated financial position. However, litigation is inherently uncertain and it is not possible to predict the ultimate
disposition of these proceedings.
