1. (a) May file a letterhead notice to amend the registration;
2. (b) May file the amended notice on May 1 of each year rather than within 30 days of the change, or on any other date that the appropriate TTB Officer may approve; and

3. (c) Must incorporate all changes submitted by letterhead notice in the next TTB F 5110.41 filed.
