text: We conducted our audits in accordance with generally accepted auditing standards in the United States of America. Those standards re q u i re that 
  
  we plan and perf o rm the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit 
  
  includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing 
  
  the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement pre s e n t a t i o n . 
  
  We believe that our audits provide a reasonable basis for our opinion.
