The employee "intentionally made erroneous accounting accrual entries" to hide millions of dollars, Macy's said. The error forced the company to delay reporting its third quarter results.

Macy's announced an employee has "hid" up to $154 million, prompting the U.S. department store chain to delay the release of its third-quarter earnings report.

An internal investigation revealed that a single employee intentionally concealed these expenses over nearly three years.
