You are the audit manager of East & Co and are reviewing the key issues identified in the files of two audit clients. Gulf Industries Co (Gulf) Gulf's year end was 31 March 2020 and the draft financial statements show revenue of 28 2 million, receivables of 5-6 million and profit before tax of 4-8 million. The fieldwork stage for this audit has been completed. A long-standing customer of Gulf owed an amount of 350,000 at the year end. Testing of receivables in April highlighted that no amounts had been paid to Gulf from this customer as they were disputing the quality of certain goods received from Gulf. The finance director is confident the issue will be resolved and no allowance for receivables was made with regards to this balance. Sea Trading Co (Sea) Sea is a new client of East & Co, its year end was 31 January 2020 and the firm was only appointed auditors in February 2020, as the previous auditors were suddenly unable to undertake the audit. The fieldwork stage for this audit is currently ongoing. The inventory count at Sea's warehouse was undertaken on 31 January 2020 and was overseen by the company's internal audit department. Neither East & Co nor the previous auditors attended the count. Detailed inventory records were maintained but it was not possible to undertake another full inventory count subsequent to the year end.
