In the normal course of serving clients, information we collect may be shared with companies that perform various services, such as custodians, transfer agents, and broker-dealers. The organizations that receive client information will use that information only for the services required and as allowed by applicable law or regulation and are not permitted to share or use this information for any other purpose.

Access to customers’ nonpublic personal information is restricted to employees who need to access that information. We use industry standard physical, electronic, and procedural safeguards to protect client information.
