This thesis studies modern guarantee concepts in unit-linked life insurance, where the guaranteed amount at the policy's maturity grows contingent on the performance of an investment fund. The problem of hedging and valuing these contingent guarantees, where the fund serves as both the underlying security and the replicating portfolio, is solved by a set of hedging derivatives, which are characterized through a fixed-point problem. Sufficient conditions for the existence of such derivatives are derived and numerical methods for their construction are developed, implemented, and tested.
