class="_mt"&gt;The tax provision for each year-to-date period is calculated by multiplying pretax income by the estimated annual effective tax rate for such period.&lt;font
class="_mt"&gt; &lt;/font&gt;Our effective tax rate can fluctuate significantly from period to period and may differ significantly from the U.S. federal statutory rate as a result of income taxed in various non-U.S. jurisdictions with rates different from the U.S. statutory rate, as a result of our inability to recognize a tax benefit for losses generated by certain unprofitable operations and as a result of the varying mix of income earned in the jurisdictions in which we operate.&lt;font
class="_mt"&gt; &lt;/font&gt;&lt;/font&gt;&lt;font
style="font-size: 10pt;"
class="_mt"&gt;We have reduced our U.S. and certain non-U.S. tax benefits by a valuation allowance based on a consideration of all available evidence, which indicates that it is more likely than not that some or all of the deferred tax assets will not be realized.&lt;font
class="_mt"&gt; &lt;/font&gt;&lt;font
class="_mt"&gt;In periods when operating units subject to a valuation allowance generate pretax earnings, the corresponding reduction in the valuation allowance favorably impacts our effective tax rate.&lt;font
class="_mt"&gt; &lt;/font&gt;Conversely, in periods when operating units subject to a valuation allowance generate pretax losses, the corresponding increase in the valuation allowance has an unfavorable impact on our effective tax rate.&lt;/font&gt;&lt;/font&gt;&lt;/p&gt;

class="_mt"&gt;We evaluate, on a quarterly basis, the need for the valuation allowances against deferred tax assets in those jurisdictions in which we currently maintain a valuation allowance.&lt;font

class="_mt"&gt;Our subsidiaries file income tax returns in numerous tax jurisdictions, including the United States, several U.S. states and numerous non-U.S. jurisdictions around the world.&lt;font

class="_mt"&gt; &lt;/font&gt;The statute of limitations varies by jurisdiction.&lt;font
class="_mt"&gt; &lt;/font&gt;Because of the number of jurisdictions in which we file tax returns, in any given year the statute of limitations in a number of jurisdictions may expire within 12 months from the balance sheet date.&lt;font
class="_mt"&gt; &lt;/font&gt;As a result, we expect recurring changes in unrecognized tax benefits due to the expiration of the statute of limitations, none of which are expected to be individually significant.&lt;font
class="_mt"&gt; &lt;/font&gt;With few exceptions, we are no longer subject to U.S. (including federal, state and local) or non-U.S. income tax examinations by tax authorities for years before fiscal year 2005.&lt;font

class="_mt"&gt; &lt;/font&gt;We anticipate that several of these audits may be concluded in the foreseeable future, including in fiscal year 2010.&lt;font
class="_mt"&gt; &lt;/font&gt;Based on the status of these audits, it is reasonably possible that the conclusion of the audits may result in a reduction of unrecognized tax benefits.&lt;font
