Siemens CEO says to float 50 to 75 percent

Siemens (SIE.DE) is eyeing a flotation of roughly 50 to 75 percent of its light bulb unit Osram on the stock exchange in the European autumn, the German engineering conglomerate's chief executive told a newspaper.

"We want to become a minority shareholder but hold a stake of more than 25 percent," Peter Loescher told German weekly Welt am Sonntag.

"Autumn could be a good time (for an initial public offering or IPO)", Loescher told the paper, adding: "We are under no pressure, we want an IPO timing that is right also for our shareholders."
