Spain's Iberia airlines said Friday it has received a takeover approach from U.S. private equity firm TPG Capital LLP, formerly known as the Texas Pacific Group. The flagship airline said TPG is studying the possibility of presenting a euro 3.6-a-share (US$4.81-a-share) bid for the company and has requested more detailed information on its finances. TPG's all-cash bid is 10 percent below Iberia's Thursday closing price of 4 (US$5.34) and values the company at euro 3.41 billion (US$4.55 billion). (AP Photo/Michael Sohn, File)
