# Collateral and Reserves

## Collateral and Reserves

{% tabs %}
{% tab title="Reserve Factor" %}
Reserves are an accounting entry in each maToken contract that represents a portion of historical interest which can be withdrawn or transferred through the protocol's governance. A small portion of borrower interest accrues into the protocol, determined by the reserve factor.\
\
The reserve factor is the percentage of interest paid to the Mare Finance. If the reserve factor is 10, then that would imply a 10% rate of interest paid on the borrowed asset allocated to Mare.
{% endtab %}

{% tab title="Collateral Factor" %}
maTokens have a collateral factor that can range from between 0-90%, and represents the proportionate increase in liquidity (borrow limit) that an account receives by minting the maToken.

Large or liquid assets tend to have high collateral factors; whereas smaller or more illiquid assets will tend to have lower collateral factors. If an asset has a 0% collateral factor, it cannot be used as collateral (or seized in a forced liquidation event). However, the asset can still be borrowed.

In summary, the Collateral Factor is the maximum you can borrow against a particular asset.<br>

**Example**: if the collateral factor for USDC is 75%, the maximum amount of USDC you would be able to borrow in other assets (assuming a deposit of 1000 USDC) would be $750.

| TOKEN | COLLATERAL FACTOR | RESERVE FACTOR |
| ----- | ----------------- | -------------- |
| KAVA  | 50%               | 20%            |
| USDT  | 85%               | 13%            |

Collateral factors, and/or reserve factors, may be adjusted from time to time, depending on factors such as the liquidity for a particular asset.
