Income taxes</b> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">The effective tax rates for the three months ended March&#160;31, 2011 and 2010 are different from the statutory rates primarily as a result of indefinitely invested earnings of our foreign operations. We do not provide for U.S. income taxes on undistributed earnings of our foreign operations that are intended to be invested indefinitely outside the United States. The effective tax rate for the three months ended March&#160;31, 2011 was further reduced by foreign tax credits associated with the new Puerto Rico excise tax. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">Commencing January&#160;1, 2011, Puerto Rico imposes a temporary excise tax on the purchase of goods and services from a related manufacturer in Puerto Rico. This excise tax is currently scheduled to expire in 2016. We account for the excise tax as a manufacturing cost that is capitalized in inventory and expensed in cost of sales when the related products are sold. For U.S. income tax purposes, a significant portion of the excise tax results in tax credits that are recognized in our provision for income taxes when the excise tax is paid. Our effective tax rate for the three months ended March&#160;31, 2011 without the impact of the tax credits associated with the new Puerto Rico excise tax would have been 18.8%. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">One or more of our legal entities file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and certain foreign jurisdictions. Our income tax returns are routinely audited by the tax authorities in those jurisdictions. Significant disputes may arise with these tax authorities involving issues of the timing and amount of deductions, the use of tax credits and allocations of income among various tax jurisdictions because of differing interpretations of tax laws and regulations. We are no longer subject to U.S. federal income tax examinations for years ended on or before December&#160;31, 2006 or to California state income tax examinations for years ended on or before December&#160;31, 2003. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">The Internal Revenue Service (IRS)&#160;is currently examining our U.S. income tax returns for the years ended December&#160;31, 2007, 2008 and 2009. As of March&#160;31, 2011, the Company and the IRS have agreed to certain transfer pricing adjustments for the year ended December&#160;31, 2009 and the Company has, accordingly, adjusted its liability for unrecognized tax benefits (UTBs) as discussed below. The remainder of this examination is expected to be completed in 2012. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">During the three months ended March&#160;31, 2011, the gross amount of our UTBs increased by approximately $72&#160;million as a result of tax positions taken during the current year. During the three months ended March&#160;31, 2011, the gross amount of our UTBs decreased by approximately $201 million as a result of resolving certain transfer pricing matters related to prior years. Substantially all of the UTBs as of March&#160;31, 2011, if recognized, would affect our effective tax rate. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif"> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> <b> </b> </div> </div> <!--DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" --> <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescription containing the entire income tax disclosure.
