What are the four types of opinion implying? How would the auditor decide which type of opinion to express? The following additional issues have arisen during the course of the audit of Minnie Co. Profit before tax is $10m. (i) Depreciation has been calculated on the total of land and buildings. In previous years it has only been charged on buildings. Total depreciation is $2·5m and the element charged to land only is $0·7m. (4 marks) (ii) Minnie Co’s computerised wages program is backed up daily, however for a period of two months the wages records and the back-ups have been corrupted, and therefore cannot be accessed. Wages and salaries for these two months are $1·1m. (4 marks) (iii) Minnie Co’s main competitor has filed a lawsuit for $5m against them alleging a breach of copyright; this case is ongoing and will not be resolved prior to the audit report being signed. The matter is correctly disclosed as a contingent liability. (4 marks) Required: Discuss each of these issues and describe the impact on the audit report if the above issues remain unresolved.
