As Asia's engine of economic growth continues to power ahead of other markets worldwide, companies in the region are looking further afield for capital to fuel their expansion.
The potential of equity markets as a source of capital is drying up and this has resulted in convertible bonds gaining in popularity.
Stuart Winchester, fund manager for Thornton Management (Asia), said the Asian convertible bond market had exploded from less than US$2 billion in 1993 to more than $25 billion today.
He said this had presented fund managers with a host of new investment possibilities.
Thornton recently won approval from the Securities and Futures Commission to sell its Asian convertible bond fund to retail investors.
The fund, which was set up in 1994, had originally been intended for institutional investors.
