In six years as the chairman of Hong Kong Exchanges and Clearing, Ronald Arculli has been praised for a number of initiatives that boosted the market - but he has also faced his share of criticism.
Arculli brought the importance of attracting international companies to choose Hong Kong for their initial public offerings to the forefront of the exchange's growth policies, helping make the exchange the world's leading IPO market for the past three years.
But as he steps down today, some will remember the controversies: the suspension of a number of listings soon after going public is one, and, more recently, the complaints from the very brokers who work in the exchange about shorter lunch breaks.
Fabric maker Hontex International was suspended from trading three months after it listed on Christmas Eve in 2009 following allegations from the Securities and Futures Commission that its prospectus contained misleading information.
In the past two months, the Financial Reporting Council has put 13 cases on the watchlist for alleged accounting problems, including some newly listed mainland firms.
Arculli denied the exchange had lowered the standards for offerings, resulting in questionable listings by mainland companies.
