The following table is supposed to show the cash flows from a $300m 5.45% pass-through with a WAC of 5.85% and a WAM of 351 months. Your job is to fill up the boxes under SMM, Pre-pmt., and the outstanding balance assuming a 210 PSA for months 1 to 4. For each box, you have to show your calculation in the empty space below the table. You must use at least up to 6 decimal points for the SMMs. For the 4 SMMs, you get 2 points each and for the other numbers, you get 8. (22)
