TUA Assicurazioni, a non-life company founded in 2003, is valued at around 300 million euros ($335 million), according to the sources. Two sources mentioned German insurance heavyweight Allianz (ALVG.DE), fellow German insurer Talanx (TLXGn.DE) and France's Groupama as potential bidders. One of them also named Italy's Itas as one of up to five parties that could bid in the second round. Talanx has expressed interest in ICCREA's non-life business and is competing with Swiss Helvetia Group (HELN.S), Groupama and Italian cooperative insurer Assimoco.
