# Repaying

:::warning
You're reading the legacy **v2** documentation. For current Parallel features, see [v3](/products/parallel-v3).
:::

Vault owners are recommended to keep their collateral ratios well above the MCR and LR to avoid liquidations despite collateral price changes. One way to maintain a high collateral ratio is to regularly repay vault debt.

Users can repay their vault debt partially or fully at any point by redeeming PAR/paUSD tokens. PAR/paUSD tokens used to repay debt are burned, removing them from circulation.
