By Elisabeth O'Leary and Teresa Larraz Mora MADRID (Reuters) - Separatist parties in Spain's Catalonia region set November 9 next year as the date for a proposed independence referendum on Thursday and agreed the wording, but the Spanish government immediately poured cold water on the plan. Catalan regional government head Artur Mas said the vote, which the Spanish government says would be unconstitutional, would ask two questions: "Do you want Catalonia to be a state?" and "Do you want that state to be independent?" Calls for independence in Catalonia, a wealthy industrial region of northeastern Spain which accounts for a fifth of the country's economic output, have grown as a prolonged Spanish recession and cuts in public spending have hit the area, creating a headache for Prime Minister Mariano Rajoy.
Six years after being taken private, Hilton Worldwide Holdings Thursday made a successful comeback to the market, jumping nine percent after its IPO raised $2.35 billion. The IPO, the largest ever in the hotel sector and the second-biggest US market debut of 2013, illustrated strong investor demand for Hilton, the world's largest hotel company by some benchmarks. Investment banks priced IPO shares at $20, on the high end of the $18-$21 range originally given, and boosted the number of shares by nearly five million compared with the initial plan. Hilton has touted a large increase in hotel rooms and a growing international presence since the chain was bought by US investment titan The Blackstone Group in 2007 for $25 billion.
