Description: From the 41st ARC: a presentation focusing on risk management of a pension plan whose benefit is the greater of a defined benefit DB and a defined contribution DC plan. Hedging strategies are derived and illustrated, recognizing that the DB guarantee is like an option.

Description: Regime switching models have become a popular tool in econometric time series modeling since their introduction in Hamilton [1989].These models have been widely applied for equity-returns for investment guarantees. A prominent risk management challenge is hedging these guarantees, given the equity regime switching process. This presentation develops some methodologies for regime-switching portfolio replication and use real world data to demonstrate and evaluate their effects. A Bayesian approach for regime switching model fitting is used, which allows for the examination of the robustness of each of the optimization methods when parameter uncertainty is present.
