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

Macy's M.N on Monday delayed its third-quarter results after finding that an employee hid as much as $154 million in expenses over years, instead issuing preliminary sales figures that fell short of Wall Street expectations.
