Though no specific date has been penciled-in, the vote is expected to take place in the month of February 2013.

Following a potential return, if approved by shareholders, Rothschild is planning to oust 12 of the 14 board members and shape a new direction for the company.

Commenting on the developments Bumi chief executive Nick von Schirnding remarked, "The calling of this general meeting will offer shareholders a clear choice between the board and its strategy of separation from the Bakrie Group, approved unanimously by the independent directors, and Nat Rothschild and his associates."

Rothschild had earlier resigned from the firm’s board following a dispute with Indonesia’s Bakrie family over alleged financial and other irregularities in Bumi Resources, wherein Bumi owns a 29% stake.

The Bakrie group had offered to buy back Bumi’s share for $1.4bn and force a split but was refused by Rothschild claiming it harmed intrests of minority shareholders.
