Freshfields Bruckhaus Deringer has been tapped as outside counsel by British financier Nathaniel Rothschild‘s mining investment firm Vallar on its acquisition of sizable stakes in Indonesia’s first- and fifth-largest coal producers.

The New York Times reported on Tuesday that Vallar would pay $3 billion for a 25 percent stake in Bumi Resources and a 75 percent stake in Berau Coal Energy, two of Indonesia’s top coal mining businesses. The cash-and-stock deal would create a company called Bumi PLC, which would be the only major Indonesian company listed on the London Stock Exchange, according to the NYT.
