  the deferred balances, as a retirement fund. Participants receive a Company match of 
  up to 4% of salary, net of any Company match received under the Company’s 401(k) 
  plan. All employee deferrals vest immediately. The Company matching contributions 
  vest ratably over a three-year period. The Company recorded charges for matching 
  contributions of $1 million in 2004, $2 million in 2003 and $1 million in 2002.
