Hilton plans $2.2b IPO

Hilton plans to sell stock worth an estimated $US2.2 billion in its initial public offering, one of the year's biggest IPOs. The return to public markets will value the US hotels operator at about $US19.2 billion. Hilton was taken private by The Blackstone Group in October 2007 for $US20 billion and was quickly hit by the global financial crisis.
