Description: Near the end of a pension plan's lifespan, after benefit accruals have ceased and the plan has reached fully funded status, a plan sponsor has the option to begin the plan termination process immediately or to maintain the plan for an extended period of time (often referred to as 'hibernation' as an alternative to termination). While immediate termination appeals to some plan sponsors, others choose hibernation for a number of reasons, including paternalism, fiduciary obligations, perceived cost differentials or simple inertia.
