# Event Risk

The 3AC, FTX, UST, and SVB events show that there are always black-swan-like events that a standard filtered historical simulation VAR risk model doesn’t detect. Concordia’s event risk add-on models worst-case event scenarios for portfolios and applies those returns similar to the price risk model to re-risk the protocol to a black-swan market move.
