Trendy Accessories Ltd is a producer of fashion sunglasses. The audit report for the year ended 30 June 2020 was signed on 5 August 2020 and along with the financial report was mailed to shareholders on 10 August.

Consider the following independent events. Assume that each event is material.

1. On 5 July, Trendy Accessories entered into a new contract to supply sunglasses to JDS, a new major department store. The contract was similar in nature to other contracts previously negotiated.

1. Trendy Accessories has invested significant funds in developing a new type of unbreakable sunglass lens. On 8 July, Trendy Accessories applied for a patent for the lens, only to discover that a competitor had lodged a similar application on 20 June. The granting of Trendy Accessories' application is now in serious doubt.

1. Internal audit has uncovered a major fraud at one of Trendy Accessories' branches. The fraud was perpetrated by two senior staff, acting in collusion over a number of years. The internal auditors released their report to management on 15 July, after a highly confidential investigation spanning several months.

1. One of Trendy Accessories' major customers, Leisure Pty Ltd, suffered a fire on 20 July. Since Leisure Pty Ltd was uninsured, it is unlikely that their accounts receivable balance will be paid.

1. On 25 July, a well-known financial planner advised his clients not to invest in Trendy Accessories due to poor long-term growth prospects. The market price for Trendy Accessories' shares subsequently declined by 40%.

1. On 16 August, the court ruled in favour of Trendy Accessories in relation to deductions claimed on its previous year's tax return. Trendy Accessories had provided for the full amount of the potential disallowances in accrued taxes payable. The Commissioner of Taxation has advised that he will not appeal the court's ruling.
