For the market value of the expected cash flows we have: Ax:n1 = Z(n)n px . Endowment Insurance Since an endowment is the sum of a term and a pure endowment insurance the arguments above apply mutatis mutandis and we get: Ax:n = A1x:n + Ax:n1 .

Obviously such a bond has less value 26 2 The Role of the Balance Sheets and of Capital than the one from an issuer which can not default. This latter bond is called risk free bond and it is normally assumed that its issuer is a government. There are two questions, which we want to answer in the sequel, namely how do we valuate such (defaultable) bonds and how can we assign a quality to such a bond, since the value of the bond obviousely depends on its default probabilities. In a first step we want to have a look at the valuation of such a bond and we want to revisit the example from above.

Normally the buyer of such bonds has to be compensated for this effect in case the bond is not called. A step up facility is such a method.
