text: In December 1999, we entered into an operating lease facility established to Ñnance the acquisition of 
  operating equipment consisting primarily of revenue-producing vehicles. In July 2002, we exercised our right 
  to purchase the equipment underlying this facility by paying $72.6 million using our excess cash, which was 
  the balance outstanding under the facility at that time. 
  
  In August 2001, we sold $450.0 million of unsecured notes in the public market. The notes bear interest 
  at 63/4% and mature in 2011. Interest on these notes is payable semi-annually in February and August. The 
  notes were oÅered at a discount of $2.6 million. Proceeds from the notes were used to repay our revolving 
  credit facility. 
  
  In order to manage risk associated with Öuctuations in interest rates and to take advantage of favorable 
  Öoating interest rates, we have entered into interest rate swap agreements with investment grade-rated 
  Ñnancial institutions. The swap agreements have total notional values of $225.0 million and $210.0 million, 
  respectively, and require our company to pay interest at Öoating rates based upon changes in LIBOR and 
  receive interest at Ñxed rates of 65/8% and 63/4%, respectively. Swap agreements with a notional value of 
  $225.0 million matured in May 2004, and agreements with a notional value of $210.0 million mature in 
  August 2011.
