Principal Waterfall
Principal Waterfall is the contractual sequence that determines how securitization cash flows are allocated among fees, interest, principal, reserves and different classes of investors.

How Principal Waterfall works
In practice, the result depends on the transaction documents, collateral performance, payment priority and the triggers that can redirect cash flows. The same label can produce different risk because collateral quality and transaction structure vary from deal to deal.
Why it matters in markets
Principal Waterfall matters because structured products redistribute the timing and severity of collateral losses across different investor classes. The legal waterfall can therefore be as important as the average quality of the underlying loans.
How to interpret Principal Waterfall
Interpret Principal Waterfall through the transaction waterfall and collateral assumptions. Check which class absorbs losses first, which triggers redirect cash, how quickly principal can return and whether servicing or prepayment behavior changes the expected path.
Limits and context
Principal Waterfall can vary materially across deals. Prospectuses, pooling and servicing agreements, indentures and trustee reports determine the actual mechanics; generic market definitions should not replace transaction-level analysis.
