“40 Act fund” is market shorthand, not a defined statutory label. It generally refers to a pooled investment vehicle registered with the Securities and Exchange Commission under the Investment Company Act of 1940. The Act regulates the fund as an investment company; other federal securities laws can separately govern its offered shares, disclosures, adviser, and trading.

The label describes a regulatory structure rather than an investment strategy. A 40 Act fund may invest in stocks, bonds, money-market instruments, commodities-related exposures, or other permitted assets, subject to its registration statement, policies, and applicable law.

The Act first defines an investment company

Section 3 of the Act includes issuers primarily engaged in investing, reinvesting, or trading in securities. It also includes certain issuers whose investment securities exceed 40 percent of total assets, excluding government securities and cash items for that test.

The statute contains exclusions and exemptions, so holding investments does not automatically make every operating business a registered fund. An issuer that falls within the definition generally must register unless an exclusion, exemption, or SEC order applies.

Registered funds use several legal structures

Section 4 identifies three principal classes: management companies, unit investment trusts, and face-amount certificate companies. Most modern retail funds are management companies or unit investment trusts.

A management company is open-end when it offers redeemable securities of its own issuance. A closed-end company is a management company that is not open-end. Mutual funds are the familiar open-end structure, while traditional closed-end fund shares generally trade in the market rather than being redeemed daily by the fund.

A unit investment trust has no board of directors and issues redeemable interests in a specified portfolio under a trust or similar instrument. Its structure differs from an actively managed fund even when both provide pooled exposure.

ETFs and interval funds fit within the framework

Many exchange-traded funds register as open-end management companies, while some use the unit-investment-trust form. ETF shares trade on an exchange, but authorized participants transact with the fund in larger creation and redemption units under the governing rules.

An interval fund is a registered closed-end fund that periodically offers to repurchase a stated portion of its shares at net asset value. It does not provide the same daily redemption feature as an open-end mutual fund, so liquidity terms matter.

Private funds are not registered 40 Act funds

Sections 3(c)(1) and 3(c)(7) exclude qualifying issuers from the statutory definition of investment company. A section 3(c)(1) fund generally limits beneficial owners and does not make a public offering. A section 3(c)(7) fund limits ownership to qualified purchasers and likewise does not make a public offering.

These vehicles are often called private funds. Their advisers and offerings may still be regulated under other federal or state laws, but the funds do not become registered investment companies merely because their advisers register with the SEC.

Registration creates an ongoing governance system

Registration requires filings with the SEC and places the fund within statutory rules addressing capital structure, custody, affiliated transactions, advisory contracts, changes in fundamental policies, reporting, and other investor-protection subjects. The exact requirements depend on the fund’s class and activities.

Registered management companies ordinarily use a board, including directors who satisfy statutory independence requirements. Unit investment trusts use a different governance model built around the trust instrument, depositor, trustee, and specified portfolio.

The Act works alongside SEC rules and exemptive provisions that have evolved over time. Understanding any current requirement therefore calls for the current statute, applicable federal regulation, SEC orders, and the fund’s filed documents.

Registration is different from tax status

“Regulated investment company,” or RIC, is a federal tax classification under the Internal Revenue Code. Many registered funds qualify as RICs, but 1940 Act registration and Subchapter M tax qualification are distinct legal tests administered under different statutes.

Likewise, “SEC registered” does not mean the SEC endorses the portfolio or predicts returns. A prospectus, shareholder report, fee table, investment policies, and liquidity terms provide more useful information about what a particular fund actually does.
