Texas Pacific Group found out the hard way that the difference between making a discreet inquiry about a big deal and informing the media of its intentions may come down to a single number--a fax number. Reuters reported that Texas Pacific Group apparently thought it had sent a fax to UBS chairman Marcel Ospel expressing interest in a new Swiss airline based on regional carrier Crossair, but sources close to the deal said the fax from Texas Pacific's ceo David Bonderman intended for Ospel was instead sent--by accident-- to Swiss weekly business journal HandelsZeitung instead. Loan Market Week's fax number may or may not be (212) 224-3956.
