DKSH, a Swiss company that earns 96% of its revenues in Asia, has announced plans to list on the SIX Swiss Exchange. The size of the initial public offering is yet to be revealed, but with a minimum 25% free float, it is likely to be well over Sfr1 billion ($1.1 billion). The company already has a small over-the-counter listing on the Berne exchange, but this will be taken out as part of the IPO exercise.
