Question：For which of the following material events should the auditor insist that the directors adjust the statement of profit or loss and other comprehensive income or statement of financial position as appropriate?
　　A. A decision taken by the directors before the year-end to issue ordinary shares and convertible debentures subject to approval at the next annual general meeting with shareholders.
　　B. Conditional acceptance, by the shareholders of a target company, of a bid invited before the year-end.
　　C. A year-end receivable balance becoming irrecoverable due to the appointment of a liquidator one week after the year-end.
　　D. A fall in the current market value of the company's recently acquired main-frame computer due to an announcement by the supplier that it will shortly be launching a new generation of computers.
　　The correct answer is: A year-end receivable balance becoming irrecoverable due to the appointment of a liquidator one week after the year-end.
　　This is because it is indicative of events that existed at the year-end (that is, that the customer was in serious financial difficulties and unable to pay).
