Random House and Penguin completed their planned merger on Monday, a tie-up that leaves their parent companies, Germany's Bertelsmann and Britain's Pearson, with 53 percent and 47 percent of the new company, respectively.

Penguin Random House will bring together the two company's physical and digital book-publishing businesses - both fiction and non-fiction for adults and children - in the United States, Britain, Canada, Australia, India and New Zealand, the group announced in Spain.

It also will combine Penguin's publishers in Asia and South Africa, Dorling Kindersley worldwide, and Random House's publishing companies in Spain, Mexico, Argentina, Uruguay, Colombia and Chile.

Random House's publishing group in Germany, Verlagsgruppe Random House, was left out of the merger and will continue to be a part of Bertelsmann.

Between mid-February and the beginning of June, Penguin Random House, which will be headquartered in New York, received approval for the merger from the U.S. Department of Justice, the European Commission and regulatory agencies in New Zealand, Australia, Canada, South Africa and China, without conditions in each case.

Penguin Random House will have more than 10,000 employees on five continents and comprise nearly 250 independent publishing imprints

As of the close of the business day on Monday, Markus Dohle, Random House's global chairman and chief executive since 2008, will take over as CEO of Penguin Random House, while John Makinson, head of the Penguin Group since 2002, will be the new company's chairman.
