When funding ratio constraints are explicitly accounted for, the optimal policies, for which we obtain analytical expressions, are shown to extend standard Option-Based Portfolio Insurance (OBPI) strategies to a relative risk context, with the liability- hedging portfolio replacing the risk-free asset. We also show that the introduction of maximum funding ratio targets would allow pension funds to decrease the cost of downside liability risk protection while giving up part of the upside potential beyond levels where marginal utility of wealth (relative to liabilities) is low or almost zero.
