I don't get the idea of using OA to invest, transfer to CDP close CPF investment account.
Based on CPF FAQ, the person need to reach 55 years old and set aside FRS in RA.
If a person has FRS in RA, he can just withdraw the OA directly from CPF.
Why is there a need to invest CPF OA, transfer to CDP and close CPF investment account, just to get the OA money.
How do I transfer my shares, bought under CPF Investment Scheme (CPFIS), to my Central Depository account?
You may apply to close your CPF Investment Account and transfer your shares to your own Central Depository account after you have reached 55 years old and have set aside your Full Retirement Sum (FRS) in the Retirement Account (RA). The FRS can be set aside fully with cash, or with cash (i.e. at least the Basic Retirement Sum) and property.
Please refer to this
FAQ for more information on how the retirement sum is set aside at age 55.
