For changes in a registered account, proof is required to justify the adjustment to the book value of your securities.
For changes in a non-registered account, it is not mandatory to attach proof to the Book Value Adjustment 27740 form, available on our Forms page under Other forms. Then, send us the completed form via the secure Message Centre or by mail.

do I do if I don't have the information to determine the book
value?
