Non-discretionary portfolios are effectively “execution only”, where the client is instructing trades. Not really relevant to show results of these portfolios as they show nothing about the skill of the firm.
GIPS states that fee-paying discretionary portfolios must be included. Non-fee-paying discretionary portfolios MAY be included in composites. Non-discretionary portfolios are specifically excluded (for the above reason). When stating “total firm assets”, this includes non-fee-paying as well as non-discretionary.
