The actual date that the structure or structure modifications became effective on the Citibank host system. The Effective Implementation Date is supplied by the back-end system.
Notes:
For an amended structure, the effective date is specified separately on each added/modified/deleted account. The date on the Structure Details is not used.
For added/modified accounts, the effective date cannot be in the past and cannot be more than two months in the future.
In Europe and North America, the deletion of an account or a structure is usually only permitted on the first date of a calendar month. This is to conform to the interest posting cycle, i.e., that an account or a structure can only be deleted once the old interest is posted and a new interest posting cycle begins.
In Asia, this is not a restriction; although, in reality, the first date of a calendar month is typically suggested as an appropriate day for a structure or account deletion.
