According to AEM on Jan 14, the discrepancy was discovered when it was doing its year-end 2023 internal stock-taking exercise.
"The initial investigation into this issue attributes the shortfall to human error in transactions with the group’s ERP system during the migration of production to the group’s Penang facility from Singapore," says AEM.
"These errors were not detected by the existing controls and processes that are in place. As a result of the company’s initial findings, it has embarked on a process to review its inventory and stock monitoring and tracking processes and systems," the company adds.
AEM says the stock-taking was an internal exercise and not part of an external audit.
