text: At December 31, 2004, we had 10 million shares available for repurchase under a 
  July 2004 authorization. 
  
  In May 2002, the Board of Directors approved a restricted stock plan. The plan 
  allowed for the issuance of up to 1 million shares of Company common stock to 
  certain key employees. The restrictions on selling these shares lapse 50% on the 
  third anniversary date from the grant date and 50% on the fourth anniversary date 
  after the grant date. Through December 31, 2004, 903,000 shares were issued, with 
  an aggregate value of $32 million. This amount was recorded as deferred 
  compensation in the accompanying consolidated balance sheet and is being 
  amortized to operating expenses on a straight-line basis through the period in which 
  the restrictions fully lapse. Amortization of deferred compensation was $7 million, 
  $8 million and $5 million for the years ended December 31, 2004, 2003 and 2002, 
  respectively, and 855,000 shares were outstanding under the plan at December 31, 
  2004. In November 2002, the Board of Directors determined that no more awards 
  would be granted under the plan.
