What Is a High Water Step Up
A high water step up is a mechanism in structured finance that adjusts the interest rate or spread once a cumulative performance threshold is reached. It is commonly used in asset-backed securities, collateralized loan obligations, and other securitized products. The step up typically rewards investors for bearing additional risk after a predefined benchmark is achieved.
How the High Water Step Up Works
In a typical structure, cash flows are distributed to tranches in a defined order. Once a high water mark or cumulative return level is met, the next tranche may receive a higher coupon or the spread over a reference rate increases. This step up encourages capital allocation and aligns incentives between sponsors and investors. The exact trigger and magnitude vary by deal terms and market conventions.
Why High Water Step Ups Matter
High water step ups help manage risk by linking returns to actual performance rather than upfront assumptions. They provide a clear incentive structure and can improve the credit profile of a transaction. Investors use these features to assess risk-adjusted return and compare opportunities across structured finance markets. For more detail on structured finance mechanics, see Investopedia.
