Our effective tax rate (ETR) for the three months and six months ended June 30, 2014 decreased as compared with the three and six months ended June 30, 2013 primarily due to our ability to benefit from previously unrecognized foreign tax credits, increased earnings in our foreign jurisdictions with rates that vary from the US statutory rate and a decrease in our Israeli oil profits tax.
In our major tax jurisdictions, the earliest years remaining open to examination are as follows: US – 2010, Equatorial Guinea – 2008 and Israel – 2009.
See Note 3. Divestitures for income taxes associated with discontinued operations.
