  **Statements of Cash Flows**
  
  The Company considers all unrestricted highly liquid investments with purchased maturities of three 
  months or less to be cash equivalents. The eÅect of non-cash transactions related to business combinations, as 
  discussed in Note 4, Business Combinations, and other non-cash transactions are excluded from the 
  accompanying Consolidated Statements of Cash Flows. 
  
  **Fair Value of Financial Instruments**
  
  The carrying amounts of cash and cash equivalents, restricted cash and marketable securities, receivables, 
  accounts payable and accrued liabilities approximate fair value due to the short maturity of these instruments. 
  The fair value of the Company's Ñxed rate unsecured notes and tax-exempt Ñnancing using quoted market 
  rates is $1,227.4 million at December 31, 2004. The carrying value of the unsecured notes and tax exempt 
  Ñnancing is $1,123.3 million at December 31, 2004. The carrying amounts of the Company's remaining notes 
  payable and tax-exempt Ñnancing approximate fair value because interest rates are variable and, accordingly, 
  approximate current market rates.
