With a withdrawal plan, the investor receives regular payments from certain investment assets. The amount to be disbursed is financed by the sale of the corresponding number of units. Investors can choose to be paid their capital plus income over a fixed period (withdrawal plan with capital depletion) or they withdraw only the investment income for an unlimited period of time (withdrawal plan with capital preservation). Withdrawal plans are particularly suited for supplementary retirement pensions. Additional contributions, additional withdrawals or termination of the investment account are possible at any time.
