From a list of 100 customer accounts, totalling $1,500,000, Sally identified eight customer accounts that exceeded materiality. She also sent ten at random. Sally sent positive confirmation requests to all eighteen accounts that totalled $500,000. One of the large accounts did not respond to the confirmation request and follow up phone calls were not answered. Two of the accounts chosen at random also did not respond. After her third attempt at getting a response, Sally chose three other accounts and got clean responses from them. Two of the large customers reported pricing errors totalling $21,778, and one of the small accounts showed a small shipping error of $380. Another small account had sent a cheque for $8,064 on December 29 and based on that, disagreed with the amount on the confirmation letter. Materiality is set at $100,000. Based on audit procedures performed, Sally has concluded that Accounts Receivable are fairly stated. Review Sallys work and identify any procedures that were not done or not done correctly.
