These group level figures include funds of funds that mainly invest in external funds (those run by other groups) or overseas funds. However, figures exclude funds investing in internal funds (i.e. those run by the same group) to avoid double counting of fund assets at group level.
This explains why the sum of the group level figures for funds under management is different to the totals shown in other reports (except in the case of ISA reports).
These figures include UK domiciled funds only.
