What change does NOT require a broker-dealer to send notice to the customer?

The choice that does not require a broker-dealer to send notice to the customer is related to changes in net worth. In the context of investment accounts and the regulations governing broker-dealers, customers are typically required to update their contact information, such as name and address, as these changes directly impact communication and record-keeping.

Investment objectives involve a customer's financial goals and risk tolerance, which are critical for ensuring that the broker-dealer's recommendations align with the client's needs. Therefore, changes in investment objectives necessitate notification to the client to confirm that the current investment strategies are still suitable.

In contrast, while net worth is an important factor that may influence a client's investment profile, its changes do not typically trigger a requirement for the broker-dealer to notify the customer because it is considered an internal consideration rather than a direct change that impacts our relationship or the account itself in a significant way. Notification is generally not mandated simply based on the fluctuation of net worth, which may not directly affect the terms of service or the investments being managed.
