Investment Company Act of 1940

The Investment Company Act of 1940 is the law that regulates investment companies — entities that pool investor money to buy securities. The Act requires mutual funds and ETFs to register with the SEC, disclose holdings and fees, limit leverage, and restrict transactions that benefit management at the expense of investors. It is the backbone of regulatory oversight for the $50 trillion mutual fund industry.

What qualifies as an investment company

An investment company is broadly defined as any entity that invests at least 40% of its assets in securities (stocks, bonds, options). Most mutual funds and ETFs are investment companies. Some hedge funds escape the definition by limiting their client base to accredited investors. Some “fund of funds” (funds that hold other funds) are also included.

Once an entity qualifies, it must register with the SEC, disclose its holdings and fees, follow governance rules, and avoid certain transactions. The Act’s logic is that when a company pools money from many small investors, those investors need protection — they cannot individually verify what the manager is doing with their money.

Registration and prospectus

Investment companies must file a registration statement and issue a prospectus before selling shares to the public. The prospectus must disclose the fund’s objective, strategy, principal risks, fees, and the adviser’s experience. The fund must also file annual and semi-annual reports showing all holdings and performance. This transparency is meant to let investors compare funds and understand what they are buying.

Fees are a major concern. The Act requires prominent disclosure of expense ratios (the annual percentage of assets paid to the fund’s adviser, custodian, and administrator). It also limits the fees the adviser can charge. For example, the adviser cannot charge a percentage that is “unreasonably high” — though Congress left it to the SEC to define “unreasonably high,” which has been contentious.

The 40% independent director rule

The Act requires that at least 40% of a fund’s board of directors be independent (have no material relationship with the adviser). Independent directors are meant to represent fund shareholders and police the adviser. In practice, independent directors have limited power — they are part-time, unpaid relative to the adviser’s compensation, and rely on adviser staff for information. They are accused of being rubber stamps.

Restrictions on leverage and risky strategies

The Act generally prohibits investment companies from issuing senior securities (debt or preferred stock) — in other words, borrowing. The rationale is that leverage amplifies losses, and if a fund borrows and then loses money, the leverage can wipe out equity holders. This prohibition was designed to prevent another 1929-type crash in which leveraged investment trusts collapsed.

Some exceptions exist. Closed-end funds (funds with a fixed number of shares and no daily redemptions) can issue debt. Funds can also use “leverage” through other means — short selling, options, derivatives — that functionally create the same effect.

Transactions with affiliates and conflicts of interest

The Act restricts “affiliated transactions” — deals between the fund and the adviser, the adviser’s parent company, or other related parties. The idea is to prevent the adviser from using the fund to benefit itself at the fund’s expense. For example, the adviser cannot direct the fund to trade through the adviser’s own brokerage and pay inflated commissions. Such transactions are generally prohibited unless the transaction committee (independent directors) approves.

The explosion of ETFs and regulatory tension

The Investment Company Act was written for mutual funds, which price once daily and trade off-exchange. ETFs are a newer structure that trades on exchanges like stocks, with minute-by-minute pricing and minimal fund structure. The SEC has had to adapt the Act to ETFs, sometimes through rule amendments, sometimes through exemptive relief. The Act’s framework is straining under the weight of modern innovations.
