TUI AG and Hapag-Lloyd shareholder Albert Ballin have picked three investment banks to prepare a possible flotation of a stake in the container shipping company in 2011.

They said they plan to mandate Credit Suisse , Goldman Sachs and Greenhill to start preparations for a stock exchange listing of Hapag-Lloyd.

At the same time, they will keep looking for strategic and financial investors interested in becoming core minority investors in Hapag-Lloyd.

Three people familiar with the matter had told Reuters on Nov. 25 that TUI, Europe's biggest tour operator, would appoint investment banks to help organise a partial IPO of Hapag-LLoyd before Christmas.

The IPO of Hapag-Lloyd, the world's fifth-largest container shipping line, is seen as a first step in a strategic reshuffle at TUI.

The reshuffle is expected to lead to combining TUI and its British unit TUI Travel Plc in 2012, company and financial sources have said. (Reuters)
