Blackstone's Hilton IPO poised be third-largest of 2013

Hilton Worldwide Holdings Inc., taken private by Blackstone Group in 2007 for $26.2 billion, filed Thursday to raise $1.25 billion in an initial public offering. At that price, the deal would be the third-largest U.S. IPO so far in 2013, according to data tracked by Renaissance Capital. Zoetis, the spin-off of Pfizer's animal health business is the largest so far at $2.2 billion, followed by ING U.S.'s $1.3 billion IPO in May.
