# ROLLOVERS
A borrower with a loan position in some **UBKLiquidityPool** may set their intent to rollover at any time prior to loan maturity.
Each **UBKLiquidityPool** is capable of accurately tracking borrow interest accrual over the lifecycle of a loan.
Rollover flags allow **UNBRK™ Protocol** infrastructure to clear this interest via a collateral based repayment at maturity, and reprice the same loan at ongoing pool interest rates, while extending the loan by the term length.
In other words,the borrower-set flag triggers an **Auto-Deleveraging (ADL)** event at maturity.
The **ADL** algorithm will execute a collateral-for-debt swap using the highest-risk assets from the borrower's account in **UBKCollateralVault**.
Note:
* A loan position that remains overcollateralized and scheduled for rollover cannot be liquidated simply because it is past maturity.
* Rollovers thus allow for a pseudo-evergreen effect on fixed-rate, fixed-term obligations.
