Addition

The additions of index constituents are categorized into two types: the index with a constant number of constituents and the index with a non-constant number of constituents.

• Index with a constant number of constituents: an addition correlates to a deletion. A constituent must be deleted when another constituent is added to keep the number of constituents constant.

• Index with a non-constant number of constituents: an addition does not correlate to a deletion.

General Rules

When the deletion is planned for an index with a constant number of constituents, a corresponding addition must be executed.

Other Rules

When a significant change in circumstance or an emergency happens, the proposal for addition can be made by the Index Committee. The addition must be completed within 24 hours.
