Understanding Risk adjusted TVL
@NotionalFinance uses Collateral Factor and Borrow Factor to determine the Risk-Adjusted LTV ratio which is used to check if an account id eligible for liquidation.
Here is an Image only thread to explain what these factors do ⬇️⬇️

Case 1:
The debt is equal to the collateral provided by the user
The colored bubbles are the visual interpretation of Debt and Collateral value
---
Here is what the Debt and Collateral values look like (shaded portion) after applying the borrow factor and collateral factor.
✂️ Haircuts (collateral factor) reduce the value of net positive assets, while 🔋buffers (buffer factor) increase the value of net negative assets.
---
Hereafter applying the factors, the TVL is called Risk-Adjusted TVL. Right now it turns out to be more than 1 which implies this account needs to be liquidated.
---
Let us calculate the liquidation point i.e. maximum LTV.
Maximum LTV is reached when the Risk-adjusted TVL is at 1
Here is how it looks:
---
Here is what the actual Debt and Collateral values look like after considering the Borrow Facto and the Collateral Factor.
---
The Borrow Factor and the Collateral Factor are different for different assets and it is based on the liquidity as well as the volatility of the particular asset.
Haircut = Collateral Factor
Buffer = Borrow Factor

Here is what the ideal condition looks like:
When the LTV is less than the Maximum LTV
