1. On 5 August 2023, a fire caused heavy damage to one of a client's two plants; the loss won't be reimbursed by insurance. The newspapers described the event in detail. The financial statements and appended notes as prepared by management didn't disclose or adjust the loss caused by the fire.

1. On 15 July 2023, Mountain Pty Ltd, a major customer of Bargain, was placed into liquidation. Bargain's management had been made aware of the financial difficulty that Mountain Pty Ltd had suffered on 30/6/2023, however, the management of Bargain at that time believed that the situation was just temporary, and it would not affect its ability to collect the full amount that Mountain was owing at 30/6/2023. Therefore, there was no adjustment or disclosure made to the 30/6/2023 financial statements.

1. On 25 July 2023, there was a report from a well-known short-selling company advising its clients not to invest in Bargain due to poor long-term growth prospects. The market price for Bargain's shares subsequently declined by 35%.

However, when reviewing the 'Overview of Operation" section, which is to be included in the annual report that contains the audited financial report, you see that the revenue to be generated over the next five years includes revenue created by Chadstone Pty Ltd.

For each of the above events, state the appropriate action (if any) that the auditor would require of the client in order to issue an unmodified audit opinion. Give reasons and make references to relevant auditing standards.
