Pressure grows on Tinkler as Whitehaven dives Whitehaven Coal shares collapsed to a fresh low today, putting Nathan Tinkler under maximum financial pressure as the former billionnaire readies for a public examination next Friday by the liquidator of his Mulsanne Resources. Whitehaven shares have plunged by 25 cent since the start of the year, in the wake of a sharp January profit downgrade and the announcement that respected managing director Tony Haggarty will retire by Easter. Mr Tinkler's main asset, a 19.4 per cent stake in Whitehaven, has dropped in value from $710 million to just $532 million at today's prices. That is significantly less than Mr Tinkler's total debt to hedge fund Farallon Capital, believed to be about $700 million including principal and accumulated interest, as Fairfax Media has reported previously. The shares touched an all-time post-merger low of $2.705 before recovering slightly to be down 2.1 per cent at $2.74 in afternoon trade. The fresh low comes as Mr Tinkler's luxury Dassault Falcon executive jet was advertised today with a price tag of $US13.95 million ($13.7 million), while the eight-seater Augusta A109S helicopter was listed for $US5.95 million. Lawyers for Mr Tinkler and his colleagues at Mulsanne, who will also face examination - including fellow directors Troy Palmer and Matthew Keen, and company secretary Aimee Hyde - on Thursday delivered a box full of documents to Ferrier Hodgson, over a failed $28.4 million share placement by listed coal explorer Blackwood Corporation. NSW Supreme Court registrar Joanne Hedge ordered the four examinees to produce the share placement agreement documents by February 15 but granted an extension until Thursday, the end of the month. Mr Tinkler's personal financial affairs will also be subject of the examination and Mr Tinkler was ordered to provide his bank statements by March 8, and the balance of documents relating to his financial affairs by March 13. Among his supporters, Mr Tinkler nominated four possible financiers to assist Mulsanne in completing the transaction with Blackwood, including locally-based Credit Suisse and EIG Global Energy Australia, which were ordered to produce documents ahead of the hearing. EIG has confirmed it has no documents to provide and Credit Suisse has indicated it will serve documents by the due date of March 6. Mr Tinkler also nominated foreign entities Noonday Asset Management - an arm of hedge fund Farallon Capital - and Jefferies Singapore Ltd, and the liquidator Robyn Duggan has written to both requesting delivery of any documents they hold regarding an application for finance relating to the Blackwood transaction. ""Noonday has communicated with us and we expect to have a response from them next week,"" Ms Duggan said. Mr Tinkler's co-directors were ordered to provide their own personal financial documents by the close of business today. Ferrier Hodgson is investigating possible insolvent trading by Mulsanne's directors - which could leave them personally liable for debts incurrred by the company. Next Friday's public hearing is scheduled to continue on March 14 and 15 and will examine the circumstances surrounding the entry of Mulsanne Resources into the share placement agreement with Blackwood. Ms Duggan said the hearings could only be avoided if Mulsanne paid the $28.4 million owed to Blackwood or reached an agreement which Blackwood, the major creditor, is prepared to accept. Mr Tinkler, based in Singapore, was expected to resolve the dispute with Blackwood before his private finances were dragged into public view.
