Hybrid pension plans offer employees the best features of bothdefned beneft and defned contribution plans. In this work, weconsider the hybrid design offering a defned contribution beneftwith a defned beneft guaranteed minimum underpin. This studyapplies the contingent claims approach to value the defnedcontribution beneft with a defned beneft guaranteed minimumunderpin. The study shows that entry age, utility functionparameters and the market price of risk each has a significanteffect on the value of retirementbenefits.We also consider risk managementfor this defned beneft underpin pensionplan. Assuming fxed interestrates, and assuming that salaries can be treated as a tradableasset, contribubion rates are develop tor the Entry AgeNormal(EAN), Pro jected Unit Credit(PUC), and Traditional UnitCredit(TUC)funding methods.For the EAN, the contribution rates areconstant throughont the service period. However, the hedgeparameters for this method are not tradable. For the accrualsmethod, the individual contribution rates are not constant. Forboth the PUC and TUC,a delta hedge strategy is derived andexplained.The analysis is extended torelax the tradable assumption for salaries, using the inflation asa partial hedge. Finally, methods for incorporating volatilityreducing and risk management areconsddered.
