You have reviewed the work performed by your assistant, Raymond Snow, on the audit of Tin Ltd for the year ended 30 June 20X8 and you have noted the following two independent matters: (i) In testing investments in listed securities, Raymond selected all shareholdings with a market value above $200,000 and checked them to the closing market value reported by the Australian Stock Exchange (ASX) to determine the net realisable value of each shareholding. The items tested totaled $5,500,000 or 60% of the total balance. Of the items tested, only one error of $110,000 was discovered. Raymond concluded that the error was not itself material, as it was only 2% of the balance tested. He extrapolated this error to the total population and estimated that the error for the total population would be $185,000, which was also immaterial. Therefore, he concluded that the investments in listed securities were fairly stated at the lower of cost or net realisable value
