On September 9, 2008, the Mexican Supreme Court ruled against CEMEX's constitutional challenge of the controlled foreign corporation tax rules in effect in Mexico for tax years 2005 to 2007.  Since the Supreme Court's decision does not pertain to a specific tax assessment or other tax obligations, CEMEX will self-assess any taxes due through the submission of amended tax returns.  CEMEX has not yet determined the amount of tax or the periods affected.  Based on a preliminary estimate, CEMEX believes this amount will not be material, but no assurance can be given that additional analysis will not lead to a different conclusion.  If the tax authorities do not agree with CEMEX's self-assessment, they may assess additional amounts, which may be material.  Any such additional assessments may be challenged before the tax courts.
