@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 โฌ๏ธโฌ๏ธ

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.
โ๏ธ Haircuts (collateral factor) reduce the value of net positive assets, while ๐buffers (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
