after year-end to determine that the sale is recorded in the period goods were received by the customer. (Callout #2) Our sample results (Exhibit 1) reveal two sales recorded in year 5 that should have been recorded in year 6. (Callout #3) 22 A billing clerk (Exhibit 4) informed us that in several cases, sales were not recorded (completeness). Based on the discussion, an effective audit procedure to address this would be to select a sample of invoices sent to customers and agree their details to the underlying customer purchase order and shipping document. (Callout #4) 4.11 points As a part of the audit of sales to unauthorized customers (above, top paragraph), we selected a sample of 40 sales invoices and found that three in our sample were to unauthorized customers. As indicated above, Exhibit 1 details our sample; Exhibit 2 presents results relating to the sample. The most likely deviation rate in the population is 5 percent (Callout #5). The sample results in "rejection" because the achieved upper deviation rate exceeds the sample deviation rate (Callout #6). Because we do not intend to expand our sample, the most likely effect on our audit will be a decrease in the assessed level of control risk (Callout #7) for the related assertion(s). eBook References Callouts Determination 1.
