In July 2010 Vallar plc, a Jersey-incorporated investment vehicle founded by Nathaniel Rothschild, raised £707.2 million ($1.07 billion) in an Initial public offering on the London Stock Exchange.

Vallar decided to focus on investments in mining of metals, coal, and iron ore in the Americas, Russia, Eastern Europe, and Australia.

[3] In November 2010, Vallar announced it was buying stakes for $3bn in two listed Indonesia thermal coal (used for power stations) producers for a combination of cash and new Vallar shares, with a view to combining them to create the largest exporter of thermal coal to China, India, and the other emerging economies of Asia.

[5] In September 2012 the company announced that it was looking into possible financial irregularities at its Indonesian arms resulting in a 14% fall in its share price.

[7] In 2013, it was variously reported that $173 million had allegedly gone "missing" or that "mysteriously vanished" or that a withdrawal was "unauthorised" from Berau Coal Energy (a subsidiary of Bumi plc) under Rosan Roeslani's leadership.
