For this reason, Credit Manager grants higher MaxLTV & LiqThreshold parameters, +granting higher leverage. An asset's HLS parameters are stored in this contract and are applied to credit accounts +of the HLS type during a health check. + +### De-listing an HLS asset + +There are a few scenarios depending on what denom is being de-listed. Always communicate each step to the users! +- **De-listing a collateral denom**: + - Set the MaxLTV of the denom to zero. + - Gradually reduce the HLS Liquidation Threshold to zero. + - _Do not_ set HLS parameters to None or remove it from correlations list for debt denom. This would result in freezing the HLS accounts that have that collateral. +- **De-listing a debt denom**: + - Set the MaxLTV of all denoms in the debt denom's correlations list to zero. + - Gradually reduce the HLS Liquidation Threshold to zero. + - _Do not_ set HLS parameters to None.
