SINGAPORE - Two Singapore companies, chipmaker Avago Technologies and logistics firm CWT, have made it to the list of the region's best big publicly-traded firms put together by Forbes Asia.

The list, known as the Fabulous 50, selects from a pool of 1,116 listed companies in the region with at least $3 billion in annual revenue or market capitalisation.

Companies are analysed for a long series of performance measures, including revenue, profits, return on capital, share price movements and outlook. The list excludes companies with too much debt or where the government owns at least half of the shares.

Firms from China dominate the list - China has 25 names on the list, up from 16 last year, and more than any other country for the fifth year in a row.

It also boasts the list's most valuable company - Tencent, now worth $176.5 billion - and its biggest, Lenovo, which generated $46.3 billion in revenue last year.

Companies must be publicly traded for at least a year to be in the running, so internet giant Alibaba, which listed last September, will get its first chance next year.
