An insured depositor has a claim against the institution and a contingent claim against the insurer. This paper analyzes the effect of the riskiness of the asset mix and the relative amount of deposits and capital on the potential liability of the insurer. It shows that an increase in asset risk, holding value constant, increases the value of equity and raises the potential liability of the insurer. ER -
