Investment Adviser Definition

The Uniform Securities Act (USA) and Investment Advisers Act of 1940 define who qualifies as an investment adviser. Understanding these definitions is crucial for the Series 66 exam.

The Three-Prong Test

A person is an investment adviser if they meet ALL THREE criteria:

ProngRequirementKey Points
1. AdviceGives advice or analyses about securitiesIncludes recommendations, research, opinions
2. BusinessIs in the business of giving adviceRegular activity, not isolated instances
3. CompensationReceives compensation for the adviceANY economic benefit qualifies

Critical: If ANY prong is missing, the person is NOT an investment adviser.

Understanding "Compensation"

Compensation is interpreted broadly under securities law:

  • Direct fees (flat, hourly, AUM-based)
  • Commissions on product sales
  • Referral fees
  • Soft dollar arrangements
  • Discounts or free services
  • ANY economic benefit received

Understanding "In the Business"

Being "in the business" means:

  • Providing advice on a regular basis
  • Holding yourself out as providing advice
  • Receiving separate or special compensation for advice

Not in the business: Occasional advice given incidentally during other activities.

Exclusions from the Definition

These persons are NOT investment advisers under the USA (even if they meet all three prongs):

The LATE Exclusion

ProfessionalCondition for Exclusion
LawyersAdvice is incidental to legal practice
AccountantsAdvice is incidental to accounting practice
TeachersAdvice is incidental to teaching profession
EngineersAdvice is incidental to engineering practice

"Incidental" means:

  • Not the primary service being provided
  • Not holding out as an investment adviser
  • Not charging separately for investment advice

Exam Trap: If a CPA charges separately for investment advice or holds out as an adviser, they ARE an investment adviser.

Other Exclusions

ExclusionRequirements
Banks and Trust CompaniesState or federally regulated
Broker-DealersAdvice incidental to BD activities, no special compensation
PublishersGeneral circulation, not tailored to individual clients
Newspaper/Magazine ColumnistsGeneral circulation, impersonal advice
Federal Covered AdvisersRegistered with SEC (excluded from state definition)

The Publisher's Exclusion

To qualify for the publisher's exclusion:

  • Publication must be of general and regular circulation
  • Content cannot be tailored to individual subscribers
  • Publisher cannot provide personalized advice
  • Must be bona fide publication (not a sham)

Example: A newsletter recommending specific stocks to all subscribers = excluded. Example: A service providing personalized stock picks = NOT excluded.

Federal vs. State Registration

SEC Registration (Federal Covered Advisers)

Adviser TypeRegistration
$110 million+ AUMMust register with SEC
$100-110 million AUMMay register with SEC
Advisers to registered investment companiesMust register with SEC
Multi-state advisers (15+ states)May register with SEC
Internet advisersMay register with SEC
Pension consultants ($200M+ advised)Must register with SEC

State Registration

Adviser TypeRegistration
Under $100 million AUMState only
$100-110 million AUMState or SEC (choice)
Place of business in stateMust register with that state

Switching Thresholds

  • SEC → State: When AUM falls below $90 million
  • State → SEC: When AUM reaches $110 million
  • Buffer zone: $100-110 million provides flexibility

De Minimis Exemption

An adviser may be exempt from state registration if they:

  • Have no place of business in the state
  • Have 5 or fewer clients in the state during the past 12 months
  • Do not hold themselves out as advisers in that state

Counting Clients for De Minimis

Counted as ONE client:

  • A corporation or business entity
  • A trust (not individual beneficiaries)
  • A married couple with joint account

NOT counted:

  • Other advisers
  • Institutional buyers
  • Existing clients who relocate to the state (grace period)

Notice Filing for Federal Covered Advisers

While federal covered advisers don't register with states, they must:

  • File copies of SEC filings with states where they have a place of business
  • Pay state filing fees
  • Submit to state antifraud authority

Exam Tip: The three-prong test requires ALL three elements. Remember LATE exclusions require advice to be INCIDENTAL. The de minimis exemption is 5 or fewer clients with no place of business.
