auditing

The following are independent and material situations: Situation 1: A client holds a note receivable consisting of principal and accrued interest receivable. The note's maker recently filed a voluntary bankruptcy petition, but the client failed to reduce the recorded value of the note to its net realisable value, which is approximately 20 percent of the recorded amount. Situation 2: An auditor is engaged to audit a client's financial report after the annual physical inventory count. The accounting records are not sufficiently reliable to enable the auditor to become satisfied as to the year-end inventory balances. Situation 3: An auditor hires an expert to assist in corroborating a client's complex superannuation calculations concerning accrued superannuation liabilities that account for 35 percent of the client's total liabilities. The expert's findings are reasonably close to the client's calculations and support the financial report.
