    This column represents the monthly reduction in the Aggregate Securitization Value, assuming(1) each collection period is a calendar month rather than a fiscal month,(2) timely receipt of all monthly rental payments and sales proceeds,(3) no credit or residual losses and(4) no prepayments (including defaults, purchase option exercises  or other early lease terminations).Actual cash flows are likely to vary from these amounts.
