On the advice of his accountant, Mat registered a private limited company to conduct his small manufacturing business in January 2010. One of the reasons for establishing the company was to avoid liability for potential losses. The initial shareholders of the company were Mat, his wife Mary, and her father Norm, who each took 1,000 shares in the company, each with a nominal value of ￡1. The accountant explained that they did not have to pay the full nominal value of the shares at once, so they each paid only 25 pence per share taken, with the result that they still owed the company a further 75 pence per share to be paid at a later date.When the company was established it became apparent that it needed to borrow money from a bank to finance an expansion in production. To that end Oop bank plc lent the company ￡20,000 secured by a fixed charge against the land Mat had previously transferred to the company, with an additional personal guarantee from Mat for any further debts owed by the company to the bank.Unfortunately the business has not proved successful and Mat and the other shareholders have decided that it is better to liquidate the company rather than run up any more debts. The current situation is that the company’s land is worth ￡20,000 and it has further assets to the value of ￡7,750, but it has debts to business creditors of ￡10,000 and owes the bank a further ￡10,000 on its bank overdraft.Required:Explain the rights of the various creditors and the potential liability of Mat, Mary and Norm. (The actual costs of winding up may be ignored.) (10 marks)
