Some muslim bumis don't prefer ASB because it is non-syariah compliance, even though Majlis Fatwa Kebangsaan stated that it is "harus". Most of Malays around me put their money in Tabung Haji even though the return is just around 5%, or lower.
Some muslims don't give a damn about it. Non-muslim bumi, well for sure they just want the best return, that's all. So if you keep saying that ASB has lower subscription, it's because of syariah compliance issues on ASB funds.
This fund could be an alternative to them, so I don't think this will fail.
