For these purposes, they sometimes use traditional methods and, in some instances, apply "extreme value" theory.6 The so-called traditional scenario approach is generally developed on the basis of observation and qualitative analysis of past events; for example, the Asian crisis of 1997–98, the Russian debt restructuring in 1998, and the.
