  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Commencing
  in the first quarter of 2008, Chemtura Corporation (the &#147;Company&#148;) will
  reclassify the presentation of certain costs in its financial statements
  between selling, general and administrative (&#147;SG&amp;A&#148;) and costs of goods
  sold for all periods presented.&#160; These
  reclassifications are being made to reflect the deeper understanding the
  Company now has of its costs following improvements resulting from a review
  of&#160; its cost review and analysis
  processes.&#160; The reclassifications made
  from SG&amp;A to cost of goods sold include increasing the allocation of
  insurance premiums and costs associated with the processing of customer orders.</font></p>
  
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">It
  is the Company&#146;s policy to improve the presentation of its financial statements
  to both reflect improvements in analysis and the evolution of its
  businesses.&#160; These reclassifications will
  be consistently applied in future reporting periods.&#160; The reclassifications between SG&amp;A and
  cost of goods sold have no impact on the Company&#146;s consolidated pretax income,
  income taxes, net income, total assets or total liabilities.</font></p>
  
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
  Company is also revising allocation methodologies of its functional and other
  expenses between its segments. The new methodology supports the recent Company
  organizational changes to streamline decision making by providing each business
  responsibility for its own production facilities, operational forecasting,
  sourcing decisions, process excellence initiatives and technical development by
  now better aligning the functional and other expenses with the activities of
  the business.&#160; These changes will drive a
  better understanding of the costs attributable to each business segment and
  thereby segment profitability.&#160; The
  re-allocation of expense between segments and the reduction in general
  corporate expense have no impact on the consolidated results.</font></p>
  
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Additionally,
  the Company will now refer to its non-GAAP financial measures as the &#145;managed
  basis&#146; presentation, as this more accurately reflects the purpose of the
  disclosures.&#160; The Company believes the
  managed basis presentation provides useful information to investors and may
  assist them in evaluating the Company&#146;s underlying performance and identifying
  operating trends.</font></p>

  8.01 Other Events
  Commencing
  in the first quarter of 2008, Chemtura Corporation (the "Company") will
  reclassify the presentation of certain costs in its financial statements
  between selling, general and administrative ("SG&A") and costs of goods
  sold for all periods presented.  These
  reclassifications are being made to reflect the deeper understanding the
  Company now has of its costs following improvements resulting from a review
  of  its cost review and analysis
  processes.  The reclassifications made
  from SG&A to cost of goods sold include increasing the allocation of
  insurance premiums and costs associated with the processing of customer orders.
  It
  is the Company's policy to improve the presentation of its financial statements
  to both reflect improvements in analysis and the evolution of its
  businesses.  These reclassifications will
  be consistently applied in future reporting periods.  The reclassifications between SG&A and
  cost of goods sold have no impact on the Company's consolidated pretax income,
  income taxes, net income, total assets or total liabilities.
  The
  Company is also revising allocation methodologies of its functional and other
  expenses between its segments. The new methodology supports the recent Company
  organizational changes to streamline decision making by providing each business
  responsibility for its own production facilities, operational forecasting,
  sourcing decisions, process excellence initiatives and technical development by
  now better aligning the functional and other expenses with the activities of
  the business.  These changes will drive a
  better understanding of the costs attributable to each business segment and
  thereby segment profitability.  The
  re-allocation of expense between segments and the reduction in general
  corporate expense have no impact on the consolidated results.
  Additionally,
  the Company will now refer to its non-GAAP financial measures as the 'managed
  basis' presentation, as this more accurately reflects the purpose of the
  disclosures.  The Company believes the
  managed basis presentation provides useful information to investors and may
  assist them in evaluating the Company's underlying performance and identifying
  operating trends.
  The
  attached financial and statistical information has been prepared to reflect the
  reclassification and changes described above had they been applied for the
  years ended December 31, 2007 and 2006 and the quarters ended March 31,
  June 30, September 30 and December 31, 2007.  They are furnished herein in Exhibit 99.1
  and are incorporated herein by reference.
