Under unclaimed or abandoned property statutes, States may consider investor accounts dormant where there is an absence of documented owner-generated contact or when multiple attempts to contact the investor have resulted in returned mail. These rules apply within a defined period of time, typically 3 or 5 years. The shareholder’s stock is considered “dormant” if there is no owner-initiated contact. Per individual State unclaimed or abandoned property laws, due diligence letters are mailed out to shareholders to alert them that their accounts are at risk of becoming dormant.
