Quick Answer
An investment adviser meets all three prongs (advice, business, compensation). Certain persons are excluded from the definition (lawyers, accountants, teachers, engineers, banks, broker-dealers, publishers); de minimis advisers skip registration, and private-fund advisers are exempt from full SEC registration though states may still require it. Assets-under-management thresholds split state from federal registration.
The whole unit on one sheet: who is an investment adviser, who escapes the definition, who skips registration, and the numbers that decide state versus federal oversight.
Which One-Liners Win Points?
- All three prongs must be met. Missing any one prong means the person is not an investment adviser (IA).
- Compensation can be indirect and need not come from the person receiving advice. A third-party referral fee still satisfies the compensation prong.
- Excluded persons are NOT investment advisers; exempt persons ARE investment advisers who simply skip registration.
- The lawyer / accountant / teacher / engineer (L.A.T.E.) exclusion applies only when advice is solely incidental to the profession. Marketing financial planning as a separate offering loses it. The "no special compensation" condition belongs to the broker-dealer exclusion, not to L.A.T.E.
- Broker-dealer (BD) exclusion needs two conditions: advice solely incidental to the BD business AND no special compensation. A wrap fee is special compensation and destroys the exclusion.
- Publisher exclusion requires a bona fide publication of general, regular circulation with non-tailored advice; personalized portfolios lose it. A subscription or access fee does not defeat it.
- Banks must be domestic to claim the exclusion; foreign banks do NOT qualify.
- Advice solely on U.S. Government securities is excluded under federal law but NOT under state law.
- Federal covered advisers only notice file with states; they do not register at the state level.
- ERAs are still subject to SEC antifraud provisions, and states retain antifraud authority over every adviser operating within their borders, including federal covered advisers.
Which Numbers Matter Most?
| Item | Value |
|---|---|
| Under $25 million assets under management (AUM) | Must register with the state (barred from SEC) |
| $25 million to $100 million ("mid-size adviser") | Registers with the state of the principal office (SEC only if the state does not examine) |
| $100 million to $110 million | Eligible but not required to register with SEC |
| $110 million and above | Must register with SEC as a federal covered adviser |
| The $90 million / $110 million buffer | Register with SEC at $110M, only de-register at $90M (prevents constant switching) |
| De minimis exemption | No place of business in the state AND 5 or fewer retail clients in the preceding 12 months |
| Notice-filing client trigger | Place of business OR 6 or more retail clients resident in the state (institutional clients don't count) |
| Private fund adviser exempt reporting cap | AUM under $150 million (venture capital fund adviser has no cap) |
Exam Tip: Gotchas
- The ABC test is all-or-nothing. Advice, business, and compensation are cumulative; the exam plants scenarios where one prong quietly fails.
- Exclusion vs. exemption is a favorite trap. An excluded person (bank, L.A.T.E., BD, publisher) is not an IA at all; an exempt person (de minimis, private fund) IS an IA who skips registration.
- De minimis requires BOTH conditions. No place of business in the state AND 5 or fewer retail clients there. An office in the state kills the exemption regardless of client count; institutional clients do not count toward the cap.
- The mid-size "state does not examine" fallback has one name: New York. It is the only state that does not examine its state-registered investment advisers, so a mid-size adviser ($25M-$100M AUM) headquartered there must register with the SEC: mandatory, not an election like the 15-or-more-states rule.
What Are the ABC Prongs of an Adviser?
- Advice (about securities)
- Business (in the regular business of providing it)
- Compensation (any economic benefit, direct or indirect)
Exam Tip: Gotchas
- A mutual fund advisory contract means federal covered, period, even at $10M AUM. The AUM test does not apply.
- Federal covered = notice filing, not registration. The SEC stays the primary regulator, but the state keeps antifraud authority.
- The government-securities exclusion is federal only. An adviser solely on Treasuries may still have to register at the state level.
One-Breath Recap
An investment adviser is anyone who clears the ABC test: advice about securities, as a regular business, for any compensation, direct or indirect. Some persons are excluded from the definition outright (lawyers, accountants, teachers, engineers when incidental; domestic banks; broker-dealers with no special compensation; publishers of general circulation), while de minimis advisers meet the definition but skip registration, and private-fund advisers are exempt from full SEC registration though states may still require registration or a notice filing. Registration splits on assets under management: under $25 million is state-only, $25 million to $100 million is the mid-size state band, and $110 million and above is federal covered, with a $90 million / $110 million buffer that stops firms from flipping back and forth. Federal covered advisers only notice file, and states keep antifraud authority over everyone.
