Investment Company Structure
Quick Answer
The Investment Company Act recognizes three management company types plus UITs. Open-end mutual funds issue redeemable shares at forward NAV; closed-end funds issue fixed shares that trade on exchanges and can sell at a premium or discount to NAV; UITs hold fixed portfolios that terminate; ETFs blend open-end structure with exchange trading.
With the tax framework in place, you can now see the three vehicles Subchapter M applies to: open-end funds, closed-end funds, and Unit Investment Trusts (UITs). Exchange-Traded Funds (ETFs) are a hybrid that blends open-end or UIT structure with secondary-market trading.
What are the three investment company types under ICA Section 4?
The Investment Company Act (ICA) of 1940 recognizes three management investment company types, plus UITs. The practical distinction is how shares are issued and priced.
| Type | Structure | Securities Issued | Pricing |
|---|---|---|---|
| Open-end (mutual fund) | Continuously issues and redeems redeemable shares | New shares issued on demand; shareholders redeem directly with the fund | Net Asset Value (NAV) forward pricing (Rule 22c-1) |
| Closed-end fund | Fixed number of shares issued in a one-time Initial Public Offering (IPO); subsequent trading on an exchange | Non-redeemable common shares; may also issue preferred stock and debt | Market price set by supply and demand; can trade at a premium or discount to NAV |
| UIT (Unit Investment Trust) | Fixed portfolio of securities held by a trustee; no active management; terminates on a stated date | Redeemable units (can sell back to sponsor/trustee at NAV) | NAV-based (units redeemable with sponsor) |
Exam Tip: Gotchas
- Only mutual funds issue shares that are redeemable directly with the issuer. Closed-end funds and ETFs are traded in the secondary market: the investor sells to another investor at market price, not back to the fund at NAV.
- "Redeemable" is the legal distinguisher under Section 4. Open-end funds and UITs issue redeemable securities; closed-end funds do not.
What are the characteristics of an open-end mutual fund?
Open-end funds are the flagship Series 6 product. The rep sells the fund, the customer sends money, the fund issues new shares, and the customer can redeem those shares back to the fund whenever they want.
- Net Asset Value (NAV): total assets minus total liabilities, divided by shares outstanding
- Forward pricing (Rule 22c-1): purchase and redemption orders execute at the next-computed NAV after order receipt
- Orders received before the fund's daily pricing time (typically 4:00 p.m. Eastern Time (ET) when U.S. markets close) receive that day's NAV
- Orders received after 4:00 p.m. ET receive the next day's NAV
- Public Offering Price (POP) for a load fund: NAV + sales charge
- Exchange privileges within fund families: investors can swap between funds in the same family, typically without a new sales charge; each exchange is still a taxable event
Think of it this way: Forward pricing is like ordering at a restaurant with no prices on the menu. You place the order; you do not know the price until after the kitchen closes and the chef totals the day's receipts. This prevents someone who already knows today's price from "late trading" at a stale, known NAV.
Exam Tip: Gotchas
- Forward pricing is a one-way street. An order submitted at 3:58 p.m. ET gets today's 4 p.m. NAV; an order at 4:02 p.m. ET gets tomorrow's NAV. This is the rule that prevents late trading, covered later in this unit.
- Exchanges within a fund family are still taxable events even though no sales charge applies. The old fund is sold (gain or loss recognized) and the new fund is purchased.
How does a closed-end fund differ from a mutual fund?
Closed-end funds raise money once, through an IPO, then let the shares trade on an exchange like any stock. The fund does not issue new shares on demand and does not redeem shares at NAV.
- Distributed in the primary market at the IPO price (one-time offering)
- Trade in the secondary market on an exchange; price driven by supply and demand
- Can trade at a discount or premium to NAV: closed-end shares do not have the NAV pricing constraint mutual funds do
- May issue senior securities (preferred stock and debt) under ICA Section 18:
- Debt: 300% asset coverage required
- Preferred stock: 200% asset coverage required
Think of it this way: A closed-end fund is like a closed cookie jar. Once the cookies (shares) are in the jar, no more get added and none come out directly. If you want cookies, you trade with someone else who already has some, and the price of those cookies on the open market can drift above or below the jar's official value.
Exam Tip: Gotchas
- Closed-end fund discounts are normal and common. A fund may trade 10-20% below NAV based on supply and demand alone. This is a feature of the closed-end structure, not a sign of distress.
- Open-end funds may only borrow from a bank, with 300% asset coverage. Closed-end funds have more leverage flexibility (debt + preferred) under Section 18.
What is a Unit Investment Trust (UIT)?
A UIT is the simplest investment company: buy a basket of securities at inception, hold them unchanged, and terminate on a stated date.
- Fixed (unmanaged) portfolio assembled at inception and held to the termination date
- No board of directors, no investment adviser: the sponsor creates the trust, a trustee holds the assets, and the portfolio is static
- Redeemable units: investors can redeem with the sponsor at NAV; some UITs have a secondary market
- Terminate on a specified date; successive "series" are typically offered as prior series mature
Exam Tip: Gotchas
- UITs have no investment adviser and no portfolio manager. A UIT question asking "who manages the portfolio?" is a trick: the answer is "no one actively manages it; the portfolio is fixed."
- UIT units are redeemable at NAV even though the portfolio is fixed. The sponsor stands ready to redeem.
How are Exchange-Traded Funds (ETFs) structured?
ETFs combine the open-end or UIT structure with the secondary-market trading of closed-end funds. Most modern ETFs are structured as open-end management companies.
- Structure: open-end investment company (or UIT) registered under the ICA
- Trading: shares trade on an exchange like a closed-end fund
- Creation/redemption by authorized participants in large block units (typically 50,000 shares, called creation units) keeps market price close to NAV
- ETFs typically trade within about 1% of NAV
- Intraday trading, margin eligibility, short-sale eligibility, and often lower expense ratios than traditional mutual funds
- Tax efficiency: in-kind creation and redemption minimizes taxable capital gains distributions at the fund level
Think of it this way: ETFs are a hybrid. To retail investors, they look and trade like stocks (buy through a broker, intraday, at market prices). Behind the scenes, authorized participants arbitrage any mispricing by creating or redeeming 50,000-share blocks at NAV, which is why ETF prices stay close to NAV even though they trade like closed-end funds.
Exam Tip: Gotchas
- ETF creation and redemption happen in kind at the authorized-participant level, not at the retail level. Retail customers buy and sell ETF shares on the exchange; they cannot redeem with the fund directly.
- ETFs trade like closed-end funds but stay close to NAV because of arbitrage by authorized participants. A closed-end fund has no authorized-participant mechanism, which is why closed-end discounts can persist.
