  In this paper we have devised an alternative methodological approach for
quantifying utility in terms of expected information content of the
decision-maker's choice set. We have proposed an extension to the concept of
utility by incorporating extrinsic utility; which we have defined as the
utility derived from the element of choice afforded to the decision-maker by
the availability of an object within his or her object set. We have
subsequently applied this extended utility concept to the case of investor
utility derived from a structured, financial product - an custom-made
investment portfolio incorporating an endogenous capital-guarantee through
inclusion of cash as a risk-free asset, based on the Black-Scholes
derivative-pricing formulation.
