# Lender and Rollovers

A rollover pool is the same as any other pool that is created. The only difference is the rollover pool has a further out expiry. To create a rollover pool it must be deployed from the same address you deployed the original pool with. 

Rollover pools are created by default when you create a second pool with a further out expiry with the **same collateral, lend token and deploying address.** 

{% hint style="success" %}
The collateral and lent token must be the same in order for a pool to be considered a rollover pool. **The Lend Ratio, Interest Rate and Expiry can be different from the prior pool!**
{% endhint %}

{% hint style="info" %}
If you would like to create a second pool with a further expiry that has the same lend token and collateral but **do not wish for it to be a rollover pool,** just use a different address.
