consolidated income from continuing operations before income taxes was 9 percent higher in 2011 than in 2010 , largely due to higher liquid hydrocarbon prices .
this improvement was offset by increased income taxes primarily the result of excess foreign tax credits generated during 2011 that we do not expect to utilize in the future .
the effective income tax rate for continuing operations was 61 percent in 2011 compared to 54 percent in 2010 .

e&p segment revenues increased $ 2247 million from 2010 to 2011 , primarily due to higher average liquid hydrocarbon realizations , which were $ 99.37 per bbl in 2011 , a 31 percent increase over 2010 .
revenues in 2010 included net pre-tax gains of $ 95 million on derivative instruments intended to mitigate price risk on future sales of liquid hydrocarbons and natural gas .
included in our e&p segment are supply optimization activities which include the purchase of commodities from third parties for resale .
supply optimization serves to aggregate volumes in order to satisfy transportation commitments and to achieve flexibility within product types and delivery points .
see the cost of revenues discussion as revenues from supply optimization approximate the related costs .
higher average crude oil prices in 2011 compared to 2010 increased revenues related to supply optimization .
revenues from the sale of our u.s .
production are higher in 2011 primarily as a result of higher liquid hydrocarbon and natural gas price realizations , but sales volumes declined. .
