<div align="left" style="font-size: 10pt; margin-top: 10pt"><b>3. 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 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 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 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 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 31, 2006 or to California state income tax
examinations for years ended on or before December 31, 2003.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">The Internal Revenue Service (IRS) is currently examining our U.S. income tax returns for the
years ended December 31, 2007, 2008 and 2009. As of March 31, 2011, the Company and the IRS have
agreed to certain transfer pricing adjustments for the year ended December 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 31, 2011, the gross amount of our UTBs increased by
approximately $72 million as a result of tax positions taken during the current year. During the
three months ended March 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 31, 2011, if recognized, would affect our effective tax
rate.
