International Mercantile Marine

International Mercantile Marine Company (IMM) was the transatlantic shipping trust J.P. Morgan announced on 18 April 1902 and incorporated in October 1902 to cut competition on the North Atlantic. It absorbed the American Line, Red Star Line, Atlantic Transport Line, Leyland Line, Dominion Line, and the White Star Line, which it bought for about 120 million dollars and held as a subsidiary from 1902 to 1927. J. Bruce Ismay chaired it. The trust never controlled British Cunard and underperformed.
