Relationship Between EAR and EVE • The biggest reason why is that we don't measure earnings-at- risk by adding up the present values of all future earnings flows. Typically only look at a one-year time frame (you have the same problem even if you look at a two or three year time frame). • EVE reflects the sensitivity of all periods , while EAR is measured for just a single defined period .
