We extend the classical risk vulnerability definition proposed by Gollier and Pratt (1996) and propose a new definition namely risk invulnerability which is to say a desirable background risk that has a positive mean value exceeding the precautionary saving premium makes a decision maker less risk averse with respect to other independent risk. We apply the concept to a corporate under stochastic wealth and threat of liquidation.
