• The Economic Cost of Ruin (ECOR) is an improvement on the concept of the probability of ruin (and therefore the risk of shortfall), which also reflects the severity of the ruin. Technically, this is the expected amount of the deficit. By analogy with a bond rating, it is comparable to taking into account the liquidation value of the bond in addition to the probability of default. For insurance companies, the equivalent term is expected policyholder deficit (EPD), which is the expected shortfall in funds owed to policyholders in the event of a liquidation.
