Vehicle Floorplan Payable
Vehicle floorplan payable-trade totaled $1.0 billion at December 31, 2009, and $1.4 billion at December 31, 2008. Vehicle floorplan payable-trade reflects amounts borrowed to finance the purchase of specific new vehicle inventories with manufacturers captive finance subsidiaries. Vehicle floorplan payable-non-trade totaled $357.6 million at December 31, 2009, and $453.4 million at December 31, 2008, and represents amounts borrowed to finance the purchase of specific new and, to a lesser extent, used vehicle inventories with non-trade lenders. All the floorplan facilities utilize LIBOR-based interest rates.
Floorplan facilities are due on demand, but in the case of new vehicle inventories, are generally paid within several business days after the related vehicles are sold. Our manufacturer agreements generally require that the manufacturer have the ability to draft against the new floorplan facilities so the lender directly funds the manufacturer for the purchase of new vehicle inventory. Floorplan facilities are primarily collateralized by vehicle inventories and related receivables.
