Income Taxes [Text Block]	Income Taxes The effective income tax rate is influenced by a variety of factors including the geographic and functional sources of income, the relative magnitude of these sources of income, and foreign currency remeasurement, net of any foreign currency hedge effects. The provision for income taxes is allocated on a discrete, stand-alone basis to pretax segment income and to individual items not allocated to segments. The difference between the total provision and the sum of the amounts allocated to segments is reported in the “Not Allocated to Segments” column of the tables in Note 6. Our effective income tax rates on continuing operations for the first three months of 2014 and 2013 were 52 percent and 72 percent. These rates are higher than the U.S. statutory rate of 35 percent due to earnings from foreign jurisdictions, primarily Norway in 2014 and 2013 and Libya in 2013, where the tax rates are in excess of the U.S. statutory rate. The decrease in the effective tax rate on continuing operations in the first three months of 2014 is due to higher projected annual ordinary income from our North American operations, which are in a lower tax jurisdiction, and pretax losses in Libya. The tax provision (benefit) applicable to Libyan ordinary income (loss) was recorded as a discrete item in the first three months of 2014 and 2013. Excluding Libya, the effective tax rates on continuing operations would be 53 percent and 64 percent for the first three months of 2014 and 2013. In Libya, where the statutory tax rate is in excess of 90 percent, we have had no oil liftings since July 2013 due to third-party labor strikes at the Es Sider oil terminal and there remains uncertainty around future production and sales levels.

Income Taxes

The effective income tax rate is influenced by a variety of factors including the geographic and functional sources of income, the relative magnitude of these sources of income, and foreign currency remeasurement, net of any foreign currency hedge effects. The provision for income taxes is allocated on a discrete, stand-alone basis to pretax segment income and to individual items not allocated to segments. The difference between the total provision and the sum of the amounts allocated to segments is reported in the “Not Allocated to Segments” column of the tables in Note 6.

Our effective income tax rates on continuing operations for the first three months of 2014 and 2013 were 52 percent and 72 percent. These rates are higher than the U.S. statutory rate of 35 percent due to earnings from foreign jurisdictions, primarily Norway in 2014 and 2013 and Libya in 2013, where the tax rates are in excess of the U.S. statutory rate. The decrease in the effective tax rate on continuing operations in the first three months of 2014 is due to higher projected annual ordinary income from our North American operations, which are in a lower tax jurisdiction, and pretax losses in Libya.

The tax provision (benefit) applicable to Libyan ordinary income (loss) was recorded as a discrete item in the first three months of 2014 and 2013. Excluding Libya, the effective tax rates on continuing operations would be 53 percent and 64 percent for the first three months of 2014 and 2013. In Libya, where the statutory tax rate is in excess of 90 percent, we have had no oil liftings since July 2013 due to third-party labor strikes at the Es Sider oil terminal and there remains uncertainty around future production and sales levels. Reliable estimates of 2014 and 2013 Libyan annual ordinary income from our operations could not be made and the range of possible scenarios in the worldwide annual effective tax rate calculation demonstrates significant variability. As such, for the first three months of 2014 and 2013, estimated annual effective tax rates were calculated excluding Libya and applied to consolidated ordinary income excluding Libya.
