Schlumberger and its subsidiaries are party to various 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 with respect to any currently pending legal proceedings is remote.  However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of any of these proceedings.
