ISS, a Danish cleaning company controversially taken private by buyout firms EQT and Goldman Sachs Capital Partners in 2005, is set to shake off concerns about turbulent public markets and press on with plans for a flotation later this year.

ISS chief executive Joergen Lindegaard confirmed the company's plans to float in the fourth quarter or early in 2008 in an interview with Danish paper Boersen. He added ISS and its banks, Goldman Sachs and Merrill Lynch, were in the process of drawing up a listing prospectus.
