Auditing experts told BI the available evidence suggests a failure of internal accounting controls. Following the news that Macy's discovered a sizable error in its financial records, auditing experts told Business Insider that the company must now explain how its controls broke down. Without more details, the accounting experts who spoke to BI said it is hard to understand exactly what happened.

"I wouldn't be surprised if you'll see a material weakness in internal controls because something is not working here," McKenna said.
