Yes redact anything irrelevant to CCL shares ownership - like account number.
I recently submitted Carnival form with second page of monthly statement as proof , no address just name of the institution, my name, statement date and account number ( redacted) on the page without any issues. I’ve done the same many times before.?Turn around time was 1 day, no e mail notification.
A few years ago I spoke to the shareholder benefits dept, the representative told me they prefer you don’t send in any irreverent personal information! At that time the preferred method was fax so they don’t have to be responsible for your personal information.
