Australian travel company Corporate Travel Management is embroiled in a $240 million overcharging scandal, dating back to 2019. The company, which arranges business trips for clients including the British government, has revealed that it may have: * Faked signed agreements with a UK customer * Overcharged clients and kept customer overpayments * Amended audit evidence * Failed to return refunds * Engaged in misconduct by a British executive, including non-return of refunds and charging excessive amounts The company's shares were frozen last year after its auditors found problems, and it has since hired KPMG to review the issues. Corporate Travel's chairman acknowledged the findings are "difficult and confronting" and the company may need to reverse revenue of up to $241 million.
