This loss experience takes into account financial assistance provided by Ford to dealers in limited instances. If Ford does not this assistance in the future, the loss experience of Ford Credit’s dealer floorplan portfolio may be adversely affected. This loss experience also reflects recoveries from dealer assets other than the financed vehicles. However, because the interest of the trust in any other dealer assets will be subordinated to Ford Credit’s interest in those assets, the net losses experienced by the trust may be higher *** For non-annual periods, the percentages are annualized **** Liquidations represent payments and net losses that reduce the principal balance of the receivables for the period indicated
