Media Marketing Ltd's financial statements for the year ended 30 June 2017 were audited by George Hart and Partners. The unqualified auditor's report was published alongside the directors' statements on 20 August 2017. Paul Poon, a tycoon in the publishing industry, put forward a bid to take over Media Marketing at $2.50 per share, based on the net asset value of the audited accounts (which also showed a net profit for the year of $18 million). The takeover was finalised on 30 September 2017. In October it was leaked to the press that the financial statements of Media Marketing had excluded a significant legal liability on a case, for a claim of $5 million. The case was being appealed by Media Marketing in June 2018. The outcome of the damages claim caused the company's share price to plummet. Paul Poon was extremely annoyed, partly because he had examined the accounts but overlooked the lawsuit. He decided to sue George Hart for negligence and compensation for not including an estimate for the likely damages.
