It is good news that the Singapore Exchange (SGX) has introduced three new listing committees to strengthen the listing regulatory process ("SGX introduces 3 new listing committees"; Sept 16).

As an investor of S-chip firms formerly listed on the local bourse, I hope that the SGX will go a step further to ensure that, after the firms are listed, it will have enough manpower and resources to check on their due diligence, in terms of management activities, especially when the firms are not based in Singapore.

Although strengthening the listing regulatory process bodes well for investors, the activities of firms which are not based in Singapore are not easily regulated without proper scrutiny.

The SGX should thus consider further steps to enhance the regulation of such firms, to improve the attractiveness of the capital market.
