The NISM workbook describes the foundation of an Investment Adviser's fiduciary responsibility using a Latin principle, 'uberrimae fidei'. What does this principle require of the Investment Adviser?

[ A ]The adviser must act with utmost good faith and trust, and must not profit at the cost of the client or take unfair advantage of the client's trust[ CORRECT ]

[ B ]The adviser must follow a caveat emptor (buyer beware) approach, leaving the client responsible for verifying all information independently

[ C ]The adviser must disclose conflicts of interest only when the client specifically asks about them

[ D ]The adviser must recommend only products on which no commission or fee is earned

Takeaway

Option A is correct: the uberrimae fidei (utmost good faith) principle requires the Investment Adviser to act in the client's best interest without profiting at the client's expense or exploiting the client's trust.

Derivation

Section 19.5 ('Fiduciary responsibility of Investment Advisers') states that since the adviser acts on behalf of another person to manage their financial assets, the principle of utmost good faith (uberrimae fidei in Latin) and trust must be followed, and there cannot be profit made at the cost of the client. A common error is confusing this with caveat emptor or treating disclosure as optional, when the workbook explicitly requires full and proactive disclosure, including of perceived conflicts of interest.

Why the others fail

B — The adviser must follow a caveat emptor (buyer beware) approach, leaving the client responsible for verifying all information independently

Caveat emptor is the opposite of a fiduciary standard; it shifts the burden onto the client rather than requiring the adviser to act in utmost good faith.

C — The adviser must disclose conflicts of interest only when the client specifically asks about them

The workbook requires full disclosure of all facts, including conflicts of interest and even perceived conflicts, proactively and at all times, not only on request.

D — The adviser must recommend only products on which no commission or fee is earned

Uberrimae fidei is about good faith and not exploiting client trust, not a blanket ban on earning fees; advisers can be compensated as long as the client's interest is not compromised.
