18. Pension and Other Benefit Plans
Pension Plans
Schlumberger sponsors several defined benefit pension plans that cover substantially all US employees hired prior to
October 1, 2004. The benefits are based on years of service and compensation, on a career-average pay basis.
In addition to the United States defined benefit pension plans, Schlumberger sponsors several other international
defined benefit pension plans. The most significant of these international plans are the International Staff Pension
Plan and the UK pension plan (collectively, the “International plans”). The International Staff Pension Plan covers
certain international employees and is based on years of service and compensation on a career-average pay basis. The
UK plan covers employees hired prior to April 1, 1999, and is based on years of service and compensation, on a final
salary basis.
The weighted-average assumed discount rate, compensation increases and the expected long-term rate of return
on plan assets used to determine the net pension cost for the US and International plans were as follows:
