The company said Indonesian-based Scott Merrillees will focus on his role as CFO of the company’s 85%-owned Berau Coal and would not seek re-election at the company's AGM on June 26 at which time he will stand down as CFO of Bumi.

The company warned on Friday that it had found another $94 million of accounting issues at its Berau subsidiary, stating that there was “not sufficient evidence to support the capitalisation of certain expenditures” of up to $56m for earth removal and building roads at mines owned by Berau, while it was reviewing land compensation payments of up to $38 million.

Chief executive of Bumi Nick von Schirnding said Friday the actions “underscore the fact that new management is leaving no stone unturned and that we are taking firm action to resolve all residual financial issues”

“While clearly the above findings are disappointing, it does reflect the fact that we are taking a grip and turning the corner with independent management in place at both Berau and Bumi.

“I am keen to draw a line under the legacy issues and these disclosures form part of an ongoing process of restoring investor confidence in Bumi. It is far preferable to achieve certainty and allow us then to move on with a clean slate."

Bumi said on March 19 it was delaying its results to April 24. Having warned on Friday that they would be delayed for a second time, it did not say when the full-year figures would be announced.

Bumi Resources, Asia’s biggest thermal coal exporter, posted a net loss of $666.2 million last year, a swing from a restated net income of $216.3 million in 2011.

The Jakarta-based miner also posted a weaker revenue in 2012 that was at $3.8 billion, from $4 billion a year earlier.
