These are rate tables associated with a particular manager.  It's that manager's exact deal with your agency. When calculating commissions, Advisors Assistant first looks for a custom table with specific rates for that manager.  If it does not find a custom table, it will use the default table.

Note: Each Manager Level is a separate level.  If you add a custom rate table for Manager 1, and then put that manager's name into the Manager 2 field for the coverage, Advisors Assistant will NOT use the Manager 1 table.  It will look for a custom Manager 2 table.  This is not the case for producers.  There is only 1 producer level.
