Brokers may pass fees to clients
The filing states that CEBBs and CEBSs may, but are not required to, pass through their CAT Fees to their clients, and those clients may in turn pass fees to their clients until the fee is imposed on the account that executed the transaction. If passed through, these fees could increase costs charged to investment accounts during May 1, 2026 through December 31, 2026.
