An auditor assessed the risk of material misstatement for the Existence of equipment as high. In response, the auditor would obtain the most appropriate evidence by... Recalculating accumulated depreciation at the balance sheet date. Performing analytical procedures comparing the current year's balance of equipment to the prior year's balance. Inquiring of management whether equipment was purchased during the year. Physically inspecting the equipment at the balance sheet date. Your staff auditor, David, is auditing accounts receivable (A/R). You have instructed him to use sampling for both tests of controls (verifying credit checks were run for new customers) and substantive tests of details (confirming ending A/R balances). David plans to use statistical attributes sampling to both identify new customers to test for credit checks and to identify customers' accounts for confirmation. What would be your feedback to David? Sampling cannot be used for tests of controls. Use mean-per-unit (MPU) sampling to identify customers' accounts for confirmation. Use attributes sampling to identify new customers to test for credit checks and mean-per-unit (MPU) sampling to identify customers' accounts for confirmation. Use mean-per-unit (MPU) sampling to both identify new customers to test for credit checks and to identify customers' accounts for confirmation. Great work
