Probity may initiate shut down by governance vote. The shutdown module gracefully settles all debt and equity in the system. Prices are frozen at time of shutdown, and there may be price volatility risk during this window. Generally, the shut down process can take up to 2 days. All collateral auctions must finish so that the final debt balance can be calculated. Then borrowers will be able to redeem Aurei for their collateral. When there remains system debt after collateral auctions have finished, the remaining shortfall is covered by equity position holders' underlying assets.
