SIE Mutual Funds and ETFs: Structure, Pricing, and Share Classes

Packaged products — mutual funds, ETFs, closed-end funds, and money market funds — account for a substantial portion of the SIE's "Understanding Products and Their Risks" section, which carries the highest content weight on the exam at roughly 44%. Candidates who understand the structural and pricing differences between these products can answer this category of questions with high accuracy.

Open-End vs. Closed-End Funds

The fundamental structural distinction on the SIE is between open-end and closed-end investment companies under the Investment Company Act of 1940.

Open-end funds (mutual funds) continuously issue and redeem shares directly with investors at the fund's Net Asset Value. There is no secondary market for open-end fund shares — you buy from and sell back to the fund itself. The number of shares outstanding fluctuates daily based on investor activity.

Closed-end funds issue a fixed number of shares through an IPO and are then listed on an exchange. Shares trade between investors on the secondary market at prices determined by supply and demand — not at NAV. Closed-end funds can trade at a premium (above NAV) or a discount (below NAV) depending on investor sentiment.

This distinction produces several exam questions: Which type trades on an exchange? Which type allows redemption at NAV? Which type can trade at a discount to NAV? The answers are always: closed-end, open-end, and closed-end.

NAV Calculation

Net Asset Value (NAV) = (Total Assets − Total Liabilities) / Total Shares Outstanding

For open-end mutual funds, NAV is calculated once per day after the market closes at 4:00 PM ET. An order to buy or sell mutual fund shares placed at any time during the trading day receives the NAV calculated at the end of that business day — this is called forward pricing. You never know the exact price at the time you place the order.

ETFs, by contrast, trade continuously throughout the day at market prices, just like stocks.

ETF vs. Mutual Fund: Key Pricing Differences

Feature	Mutual Fund	ETF
Pricing	Once daily at NAV after 4 PM	Continuously throughout the trading day
Where purchased	Directly from fund company	On an exchange through a broker
Intraday trading	Not possible	Possible
Minimum investment	Often $1,000–$3,000	Cost of one share
Sales charges	Yes (loads) for some	Brokerage commission or bid-ask spread

ETFs typically have lower expense ratios than actively managed mutual funds, and their structure enables a tax-efficient creation/redemption mechanism that allows most ETFs to avoid distributing capital gains.

Load mutual funds offer multiple share classes that differ in how sales charges are structured. The SIE tests whether candidates can distinguish among classes and identify which is appropriate for different holding periods.

Class A shares charge a front-end load — a sales charge applied at purchase. The load reduces the amount actually invested. Class A shares have lower annual expense ratios than B or C shares, making them cost-effective for long-term investors. Class A shares offer breakpoint discounts — reduced loads at specified investment levels (e.g., $50,000, $100,000, $250,000).

Class B shares charge a back-end load (also called a contingent deferred sales charge, or CDSC) that is applied when shares are sold. The CDSC typically declines over a 5–8 year holding period and eventually drops to zero. Class B shares also carry higher annual expenses than A shares. Most fund families have discontinued new sales of B shares.

Class C shares charge a level load — typically a 1% annual 12b-1 fee with no or minimal front-end charge and a small CDSC if redeemed within the first year. Class C shares carry high ongoing expenses, making them most appropriate only for short-term holdings where the investor wants flexibility without a large upfront charge.

12b-1 Fees

A 12b-1 fee is an annual fee charged by a mutual fund to cover distribution and marketing expenses. It is named after SEC Rule 12b-1. The maximum allowable 12b-1 fee is 1.00% per year. Funds that charge 12b-1 fees of 0.25% or less may still call themselves "no-load" funds; funds charging more than 0.25% cannot use the "no-load" label.

12b-1 fees are included in the fund's total expense ratio. They are particularly relevant for understanding Class C share costs and for identifying potential conflicts of interest when brokers recommend high-12b-1-fee funds.

Breakpoint Discounts

Breakpoint discounts reduce the front-end load on Class A shares when the investment reaches specified dollar thresholds. FINRA rules require that investors receive the benefit of applicable breakpoints and prohibit "breakpoint selling" — splitting an investor's assets across fund families or share classes to avoid qualifying for a discount.

Two mechanisms allow investors to reach breakpoints without making a single lump-sum investment:

Letter of Intent (LOI) — The investor signs an agreement to invest a specified amount over 13 months. The breakpoint discount is applied immediately, but if the investor does not complete the investment, the discount is retroactively reversed.

Rights of Accumulation (ROA) — The current value of the investor's existing holdings in the same fund family is combined with the new purchase to determine the applicable breakpoint. No time commitment is required.

Money Market Funds

Money market funds are open-end mutual funds that invest in short-term, high-quality debt instruments (T-bills, commercial paper, certificates of deposit). Their primary feature is a stable $1.00 NAV, though government money market funds and retail money market funds operate under different rules than institutional prime funds, which may allow a floating NAV and redemption gates.

Money market funds are not insured by the FDIC. They are distinct from bank money market accounts, which are FDIC-insured deposits.
