Bumi and Nat Rothschild go to war over Macfarlanes report Mr Rothschild said Bumi had been "hopelessly compromised" by the board's publication of a "redacted, truncated and censored" version of the Macfarlanes report and pointed the finger at chairman Samin Tan, claiming his own due diligence before he invested $1bn in Bumi formed the basis of the whistleblower document. "Samin Tan knew about financial irregularities involving the Bumi plc group before he joined the board, yet in his role as chairman did nothing about it," Mr Rothschild claimed, adding: "This calls into question compliance with his legal and fiduciary duties." Mr Rothschild listed various alleged financial misdemeanours at 29pc-owned Bumi Resources, its Jakarta-listed subsidiary Bumi Resources Minerals and Bumi's 85pc-held subsidiary Berau Coal, adding: "The board had neither the will nor the wit for this task, but shareholders need not give up hope of recovering their money." Mr Rothschild has called an EGM in a bid to oust 12 of Bumi's 14 directors and yesterday called for the immediate departure of new chief executive Nick von Schirnding for allegedly misleading investors over his professional qualifications. The financier added that Bumi's "speculation" that the Takeover Panel might hold him responsible for the undeclared concert party was "the height of absurdity." A spokesman for the Bakries said Mr Rothschild's position was "now untenable" and they would withdraw their proposal to buy back Bumi Resources and split from the group should he "persist in his attempts to have himself appointed to the board." A spokesman for Mr Tan said: "Macfarlanes has confirmed that Samin Tan co-operated fully with the Investigation. It is also clear that a substantial majority of the matters which were the subject of the investigation pre-date Mr Tan's involvement with Bumi. Indeed, it is Nat's unwillingness to explain who provided the investigation materials to him which has proved a major obstacle to the Macfarlanes investigation.
