Some retirement plans by PNB MetLife offer Maturity Benefits to the policyholder, while some others provide Survival benefits. Maturity Benefit is the sum PNB MetLife pays to the policyholder at the end of the policy term if he/she survives till maturity. Survival Benefit, on the other hand, is the sum PNB MetLife pays to the policyholder at the end of the premium payment term if he/she survives the term.
