# Risk Parameters

Beta Finance uses a scalable asset tier model to determine the risk configuration of assets. This means that instead of individually determining the safety loan-to-value (LTV), liquidation LTV, and liquidation bonus tokens are assigned a tier from S, AA, A, BB, B, and C, and all tokens in that tier share the same risk configuration. 

## Asset Tiers

| Tier | Safety LTV | Liquidation LTV | Liquidation Bonus |
| ---- | ---------- | --------------- | ----------------- |
| S    | 75%        | 80%             | 2.50%             |
| AA   | 72.5%      | 75%             | 5%                |
| A    | 67.5%      | 70%             | 5%                |
| BB   | 55%        | 60%             | 5%                |
| B    | 50%        | 55%             | 7.50%             |
| C    | 20%        | 30%             | 25%               |
