Whistleblower tips are the most common method of detecting occupational fraud. Research by the Association of Certified Fraud Examiners shows that more than 60 percent of frauds are uncovered by tips; in organizations with a hotline in place, tips expose more than half of all frauds. Further, nearly 40 percent of tips are received from internal employees.

Research conducted by the Association of Certified Fraud Examiners (ACFE) shows that the typical organization loses an estimated 5 percent of its revenues to fraud each year, and more than 85 percent of all occupational fraud cases involve employee theft.
