Peter Couper, the former chief financial officer of OnQ and now a consultant with satellite broadband provider Activ8Me, will face three charges arising from an ASIC investigation into share price manipulation of the shares of Bill Express.The securities regulator charged Couper with falsifying the books of Bill Express and providing misleading information to an auditor. These charges follow a second ASIC investigation prompted by information received from the administrators of Bill Express, Craig Crosbie and Ian Carlson of PPB.Bill Express directors and executives created false purchases and sales of mobile phone airtime just prior to financial reporting dates, counsel for PPB has previously told liquidator's hearings in the Supreme Court of Victoria.The airtime, referred to in Bill Express accounts and documentation as "Simex Stock", was supposedly purchased by Bill Express for $1.8 million and sold almost immediately for $5.4 million in May and December 2007.The second Simex transaction, dated 31 December 2007 in Bill Express accounts, shows a company owned by Charles Ridley as the buyer. Ridley is one of three British bankers currently in jail and facing charges relating to a scam US$501 million loan from Dubai Islamic Bank.When asked about the Simex Stock sale to Ridley in the Supreme Court in April this year, Peter Couper said Ridley bought the Simex "to help out Bill Express."The first Simex transaction, dated May 2007, shows a Sydney based company run by Larry Shutes as the buyer.However, Shutes refused to provide documentary confirmation of his purchase of Simex from Bill Express, the Supreme Court has been told on a number of occasions.According to a 2007 email that Shutes wrote to Couper, he refused because "I am not fond of porridge", the court heard.Newton Chan, an employee of Macquarie Equities, earlier this year pleaded guilty to manipulating shares in Bill Express and is currently serving 20 months in prison for the offence. Another Activ8me executive, Enzo Di Donato, has also been charged in relation to Bill Express stock rigging.
