Is This Normal? The Cost of Assuming that Derivatives Have Normal Returns
Derivatives exchanges often determine collateral requirements, which are fundamental to market safety, with dated risk models assuming normal returns.

This paper uses extreme value theory (EVT) to evaluate the cost of this margin inadequacy to market participants in the event of default. -
