The scenario described suggests a failure in the area of internal controls or financial oversight within the company. The fact that John Collins, who has custody of the company's cash assets, was able to steal a cash remittance and cover it up by recording a bad-debt write off indicates weaknesses in the system that is supposed to prevent and detect such fraudulent activities. This could be a breakdown in segregation of duties, lack of proper authorization, or insufficient checks and balances in place to ensure the accuracy and integrity of financial transactions.
