THE attempt by a rebel investor in Bowleven to promote a boardroom cull at the oil and gas firm has been dealt a blow after corporate governance specialists recommended shareholders vote against all but one of its proposals.

Crown Ocean Capital P1 has stoked controversy with a call for all the directors of Edinburgh-based Bowleven to be removed except for chief operating officer David Clarkson.

The investment firm has proposed two new directors be appointed to help implement a radical change of strategy at Cameroon- focused Bowleven.

The proposals have been denounced by the Bowleven management team led by chief executive Kevin Hart, but will be voted on by shareholders at a general meeting on 14 March.

Yesterday two firms that provide advice to investors on issues such as board appointments and executive pay joined the debate.

Institutional Shareholder Services recommended Bowleven shareholders vote against all nine of the resolutions that will be considered at the general meeting.

The Pensions & Investment Research Consultants firm has recommended shareholders oppose eight of the resolutions but support the one proposing the removal of non-executive director Phil Tracy from Bowleven’s board.

In its report ISS said: “The dissident has not made a sufficiently convincing case for the removal of the majority of the current board … and the appointment of two new director nominees”

The firm noted Bowleven’s share price performance was reflective of a sector which has been hit by the oil price fall. The Bowleven board has signalled 2017 will be a key year and taken the necessary steps to reduce general and administration costs.

While acknowledging there may be some validity in concerns expressed by Crown Ocean about capital allocation at Bowleven, ISS concluded: “We believe that company’s performance and lack of any significant concerns with regards to the operating of and oversight exercised by the board, does not indicate that change on the board is warranted at this time.”

PIRC noted a lack of clarity regarding the relevant experience of the directors proposed by Crown Ocean, Chris Ashworth and Eli Chahin. Crown Ocean has described Mr Ashworth as a seasoned corporate lawyer and Mr Chahin as a veteran turnaround specialist.

Noting that Crown Ocean has proposed Mr Chahin could if necessary act as interim chief executive to implement Bowleven’s new strategy PIRC stated: “Crown Ocean has identified what it believes this strategy should be in its statement. This raises concerns that he will be acting in Crown Ocean interest only.”

It said Crown Ocean had not explained why it intended to replace all board members, save Mr Clarkson.

“Although there are concerns about the Company’s recorded losses and the current level of Board independence, Crown’s approach cannot be supported,” PIRC concluded.

The consultancy supported the recommendation to remove Mr Tracy noting as a former operations director of Bowleven he could not be considered independent. Bowleven said it had acknowledged Mr Tracy was not considered fully independent for that reason but viewed his contribution as constructive and valuable.

Monaco-based Crown Ocean Capital has a 16.2 per cent stake in Bowleven and is owned by German financiers Christian Petersmann and Konstantin Stoyanov. It has accused Bowleven of a catastrophic financial performance and said the company is at risk of wasting its remaining $95 million (£76m) cash.

Crown Ocean wants to transform Bowleven into a holding company which will be able to return excess cash to shareholders. The firm says it is acting in the interests of all shareholders.It did not comment on the reports produced by ISS and PIRC.

Bowleven has said Crown Ocean wants to turn the company into a cash dispenser for its own benefit and lacks a strategy to maximise value from the company’s assets in Cameroon. The board says Bowleven’s Cameroon plans could deliver material upside while it has reduced overheads significantly.

All the company’s board members, including Mr Clarkson, have recommended shareholders vote against the resolutions proposed by Crown Ocean.
