In a corporate environment, a data protection officer is tasked with implementing a manual classification system for sensitive documents. The officer must ensure that employees can easily identify and classify documents based on their sensitivity levels. The classification levels are defined as follows: Public, Internal, Confidential, and Highly Confidential. The officer decides to create a training program that emphasizes the importance of manual classification and the criteria for each level. During the training, employees are presented with various scenarios to practice their classification skills. If an employee misclassifies a document that contains sensitive financial information as \"Internal\" instead of \"Highly Confidential,\" what could be the potential consequences of this misclassification?
