In 2004, Royal Nedlloyd bought the remaining shares from P&O and the company was listed as Royal P&O Nedlloyd on the Dutch stock exchange. Royal P&O Nedlloyd was acquired by the Danish A.P. Moller-Maersk Group (Maersk) in 2005 and was combined with their existing container shipping business Maersk-Sealand to form Maersk Line. As Sealand was the USA based historic innovator of container shipping, Maersk Line subsequently embodies the Dutch, British as well as Danish and American merchant marine legacy.
