All gifts and/or rebates arising from investing under the CPF Investment Scheme (CPFIS) must be converted to cash and refunded back to your CPF Ordinary and Special Accounts respectively. You are not allowed to receive gifts and/or rebates direct from your service provider as this will result in a leakage of CPF funds. Alternatively, you may also receive rebates in the form of additional units of investments under the CPFIS.
