Choice at maturity
Having built considerable wealth, you can take your choice at maturity. Depending on other incomes, you either go for capital depletion or you opt for capital maintenance. If you decide on capital depletion, you allow yourself a monthly payment made up of returns and parts of the asset base, consequently reducing assets and returns over the years. Opting for capital maintenance, you do not touch the asset base but use only its return to boost your retirement pay. Alternatively, you can mix both methods. Retiring at the age of 60, you could maintain your capital till the age of 75 and then start depleting it slowly.
