Investment Company Classification Under the Investment Company Act of 1940

The Investment Company Act of 1940 provides the regulatory framework for all pooled investment vehicles. Before diving into specific products, you need to understand the three legal classifications and the diversification test that governs how funds describe themselves.


Three Types of Investment Companies

The 1940 Act defines exactly three types of investment companies:

TypeDescriptionKey Feature
Face-amount certificate companyIssues debt certificates at a discount that pay a fixed amount at maturityRarely tested; virtually nonexistent today
Unit investment trust (UIT)Issues redeemable units in a fixed portfolio; no board of directors or investment adviserFixed portfolio, no active management, set termination date
Management companyActively managed portfolio overseen by a board of directors and investment adviserDivided into open-end and closed-end funds
  • Face-amount certificate companies are essentially historical relics; know the name, but don't expect deep questions
  • UITs and management companies are where the exam focuses its attention
  • Every mutual fund, closed-end fund, and exchange-traded fund (ETF) falls under one of these three categories

Management Companies: Open-End vs. Closed-End

Management companies are further divided into two categories, and the differences are heavily tested:

FeatureOpen-End Fund (Mutual Fund)Closed-End Fund
Share issuanceContinuously issues and redeems sharesFixed number of shares issued at initial public offering (IPO)
PricingForward-priced at net asset value (NAV) per Securities and Exchange Commission (SEC) Rule 22c-1Trades on exchanges at market price
TradingBought/redeemed through the fundBought/sold on secondary market
Premium/discountAlways transacts at NAV (plus any sales charge)Frequently trades at a premium or discount to NAV
LeverageGenerally prohibited from issuing senior securities (Section 18)May use leverage (issue preferred stock or debt with asset coverage requirements)

Key distinction: Open-end funds create and destroy shares with every purchase and redemption. Closed-end funds issue a fixed number of shares once, then those shares trade like stocks.

Exam Tip: Gotchas

A closed-end fund issues shares at IPO and then trades on exchanges at market price, which can differ from NAV. An open-end fund continuously issues and redeems shares at NAV. The exam often presents scenarios where you must identify which fund type can trade at a premium or discount.


The 75-5-10 Diversification Test

A fund may call itself diversified only if it meets the 75-5-10 test:

  • At least 75% of total assets must be invested in securities of other issuers, government securities, cash, or cash equivalents
  • No more than 5% of total assets may be invested in the securities of any single issuer (applies to the 75% portion only)
  • The fund may not own more than 10% of the outstanding voting securities of any single issuer (applies to the 75% portion only)

The remaining 25% of assets may be invested without these restrictions; the fund could put the entire 25% into a single issuer if it chose to.

A fund that does not meet this test must describe itself as non-diversified.

Exam Tip: Gotchas

The 75-5-10 test only applies to the 75% portion of the portfolio. The other 25% can be concentrated in any way the fund chooses. Exam questions may test whether the 5% and 10% limits apply to total assets or just the diversified portion; the answer is the 75% portion only.
