text: The increase in restricted marketable securities during 2003 consists of amounts transferred from 
  unrestricted cash for Ñnancial guarantees. In 2004, we liquidated a portion of these marketable securities and 
  used the proceeds to repay the $225.0 million of public notes. We used letters of credit to replace Ñnancial 
  guarantees secured by marketable securities that were liquidated. 
  
  We intend to Ñnance capital expenditures and acquisitions through cash on hand, cash Öows from 
  operations, our revolving credit facility, tax-exempt bonds and other Ñnancings. We expect to use primarily 
  cash for future business acquisitions. 
  
  *Cash Flows Used In Financing Activities.*Cash Öows used in Ñnancing activities was $437.3 million, 
  $70.4 million and $128.0 million for the years ended December 31, 2004, 2003 and 2002, respectively, and 
  primarily include proceeds from issuances of tax-exempt bonds, repayments of debt and repurchases of 
  common stock under our stock repurchase program. Dividends paid were $46.0 million and $19.0 million 
  during 2004 and 2003, respectively. In 2004, repayments of debt include the liquidation of $225.0 million of 
  public notes.
