Red chip Onfem Holdings and its subsidiary, Oriental Metals (Holdings) Co, have been suspended from trading in the stock market amid talk they are about to restructure. This is the latest in a series of restructurings, acquisitions and cash calls by red chips in recent weeks. Dharmala Securities Co research director Ben Kwong said the companies may announce a restructuring or an asset injection. Another source said they were likely to restructure, aimed partly at defining their business lines. Onfem is engaged in property, specialist construction and rare metals business while Oriental Metals is in non-ferrous metals trading and manufacturing. Their public relations agency, Beyond Communications, said an announcement would be made today and trading was expected to resume tomorrow.
