The Gemini Insurance Fund is an additional layer of protection used to ensure that customers being liquidated reduce the chances of Auto-DeLeveraging (ADL). ADL is the process whereby if customers positions being liquidated cannot be closed at or above the Zero Price, then profitable traders positions are closed against them. 

In order to ensure that this is unlikely to happen, any position that cannot be closed in the order book, at or above the Zero Price, is transferred to the Insurance Fund to manage. 

The Insurance Fund will continue to accept liquidated positions until it no longer has the capital to do so.
