In a three-tiered securitization structure, the interim cash flows are distributed sequentially, starting from the senior tranche. The mezzanine tranche receives its share of the cash flows after the senior tranche has been paid in full.

Given that the coupon rate for the senior tranche is 4% and the notional value is $100 million, the total interest payment to the senior tranche after one year is $4 million ($100 million * 4%).

The mezzanine tranche has a notional value of $40 million and a coupon rate of 6%. Therefore, the total interest payment to the mezzanine tranche after one year is $2.4 million ($40 million * 6%).

Things to Remember:

• In a three-tiered securitization structure, interim cash flows are distributed sequentially, with the senior tranche receiving its share first, followed by the mezzanine tranche, and then the equity tranche.
• Interim cash flows are calculated based on the coupon rates and notional values of the tranches, as well as the payment frequency.
• For each tranche, the interim cash flows are calculated by multiplying the coupon rate by the notional value and dividing by the appropriate payment frequency.
• Interim cash flows can be evaluated for different time periods to assess the cash flow dynamics and performance of the securitization structure.
