Schlumberger 2010 Annual Report - page 86

diversification, assessment of risk and targeting the optimal expected returns for given levels of risk are applied. The
target asset allocation is reviewed periodically and is determined based on a long-term projection of capital market
outcomes, inflation rates, fixed income yields, returns, volatilities and correlation relationships. The inclusion of any
given asset class in the target asset allocation is considered in relation to its impact on the overall risk/return
characteristics as well as its impact on the overall investment return. As part of its strategy, Schlumberger may utilize
certain derivative instruments, such as options, futures, swaps and forwards, within the plans to manage risks (currency,
interest rate, etc.) or as a substitute for physical securities or to obtain exposure to different markets.
Asset performance is monitored frequently with an overall expectation that plan assets will meet or exceed the
weighted index of its target asset allocation and component benchmark over rolling five year periods.
The expected long-term rate of return on assets assumptions reflect the average rate of earnings expected on funds
invested or to be invested. The assumptions have been determined by reflecting expectations regarding future rates of
return for the portfolio considering the asset allocation and related historical rates of return. The appropriateness of the
assumptions is reviewed annually.
