Although
Research & engineering
decreased as a percentage of revenue in 2011 as compared to 2010, it increased in
absolute dollars by $154 million. This increase in absolute dollars was driven in large part by the impact of the Smith
acquisition.
Income Taxes
The Schlumberger effective tax rate was 24.0% in 2012, 24.2% in 2011, and 17.1% in 2010.
The Schlumberger effective tax rate is sensitive to the geographic mix of earnings. When the percentage of pretax
earnings generated outside of North America increases, the Schlumberger effective tax rate will generally decrease.
Conversely, when the percentage of pretax earnings generated outside of North America decreases, the Schlumberger
effective tax rate will generally increase.
The effective tax rate for both 2011 and 2010 was impacted by the charges and credits described in Note 3 to the
Consolidated Financial Statements
. Excluding the impact of these charges and credits, the effective tax rate in 2011
was 23.8% compared to 20.5% in 2010. This increase in the effective tax rate, excluding the impact of the charges and
credits, was primarily attributable to the fact that Schlumberger generated a larger proportion of its pretax earnings in
North America in 2011 as compared to 2010 as a result of improved market conditions and the effect of a full year’s
activity from the acquired Smith businesses.
