Class A vs. B vs. C mutual fund shares

Class A shares charge the sales load at purchase, Class B shares charge it at redemption (a declining CDSC), and Class C shares charge a level ongoing fee through 12b-1 fees. Over a long hold, Class A usually costs the least for a large investment, and Class C is meant for short holding periods. The table gives the full comparison, and the sections after it cover breakpoints, the letter of intent and the 12b-1 rules the exam tests.

Class A vs. B vs. C comparison table

Class A shares (front-end)

• Class A shares assess a front-end load, a sales charge collected when an investor purchases shares.
• This share class is subject to breakpoint schedules, which reduce the sales charge as the investment amount increases.

🔑 Breakpoint schedule example

Sample Class A Breakpoint Schedule

Volume	Sales Charge
$0 - $24,999	8.5%
$25,000 - $49,999	6.5%
$50,000 - $99,999	5.0%
$100,000+	3.5%

• Breakpoint schedules reward larger purchases with lower sales charges.
• 🔑 Funds must offer breakpoint schedules if they assess the maximum sales charge of 8.5%.

Letter of intent (LOI)

If a customer doesn’t currently have enough money to reach the next breakpoint, they can sign a letter of intent (LOI). An LOI is a pledge to invest the additional amount (the shortfall) within the next 13 months. Signing an LOI lets the investor receive the lower sales charge immediately.

Worked example:

Using the schedule above, say a customer has $21,000 to invest. They could sign a $4,000 LOI, pledging to invest another $4,000 within 13 months. That qualifies them for the 6.5% sales charge today instead of 8.5%.

Backdating:

An LOI can be backdated up to three months to count earlier purchases. For example, if the investor bought $800 of the fund a few weeks before investing the $21,000, the LOI amount drops to $3,200.

Backdating does not extend the LOI period. If an LOI is backdated three months, the investor has only ten months left to complete the shortfall deposit. If the investor misses it, the fund retroactively applies the higher sales charge.

Sidenote — The LOI & holding shares in escrow

Financial firms that facilitate the purchase of class A shares bought with an LOI typically require a small portion of the investor’s shares to be held in escrow*. For example, a firm requires 5% of the purchased shares to be held in a side (escrow) account. This provides the firm with some collateral if the investor fails to fulfill the LOI. If an LOI is not fulfilled by the end of the designated period (13 months), the firm can simply liquidate enough shares held in the escrow account to pay for the higher sales charge.

*An escrow account is a legal holding account for capital (money) that may be spent later.

Rights of accumulation

However, funds may offer rights of accumulation, which can reduce sales charges on future purchases. For example, if a customer already has $40,000 invested in a fund and wants to invest an additional $10,000, the new purchase qualifies for the $50,000 breakpoint.

Breakpoint sales (violation)

Financial professionals must inform customers when they are close to a breakpoint. For example, if a customer wants to invest $23,500 in the XYZ fund, the registered representative must explain how the customer could qualify for the next breakpoint (they’re only $1,500 away). The customer’s options include:

Investing the additional $1,500 now Signing an LOI for the $1,500 shortfall Doing nothing and accepting the higher sales charge

The incentive math:

A financial professional can have an incentive to steer a customer away from a breakpoint, because the firm earns more when the sales charge is higher. Using the same schedule:

Sales charge if the customer buys $23,500 at 8.5% = $1,997.50 Sales charge if the customer buys $25,000 at 6.5% = $1,625.00

That’s a $372.50 difference. A representative who fails to tell the customer about the breakpoint is committing a violation called a breakpoint sale, which can bring regulator-imposed fines and/or suspensions. The representative must act as a fiduciary and put the customer’s interests ahead of their own.

Who gets breakpoints

Sidenote — Investment clubs:

An investment club is a group of friends or colleagues who pool money to invest together, much like a joint account shared by people with common interests. Clubs are not granted breakpoints and are charged the highest possible sales charge.

Combination privilege

Investors may also use the combination privilege, which allows purchases across multiple funds within the same fund family to be combined for breakpoint purposes. For example, an investor buying $9,000 of the XYZ Stock Fund, $9,000 of the XYZ Corporate Bond Fund, and $7,000 of the XYZ US Government Bond Fund would qualify for a $25,000 breakpoint.

Suitability

• Class A shares are generally most suitable for long-term investors investing larger amounts.
• Because the front-end load can be substantial, selling too soon can make the sales charge a large drag on returns. A longer holding period gives the investment more time to potentially earn returns that outweigh the initial sales charge.

Class B shares (back-end)

• Class B shares assess back-end loads, meaning the sales charge is paid when the investor sells (redeems) shares.
• This type of back-end load is also called a contingent deferred sales charge (CDSC).
• A CDSC typically declines the longer the investor holds the shares.

🔑 CDSC schedule example

Sample Class B CDSC Schedule

Years of ownership	Charge
1 year	6%
2 years	5%
3 years	3%
4 years	1%
5+ years	0%

• A CDSC schedule reduces the sales charge for longer holding periods.
• If a CDSC applies at redemption, the fund deducts the charge from the redemption proceeds before paying the investor.
• Most CDSC schedules eventually reach a point where no sales charge is due. In this example, shares held for 5 years or longer can be redeemed with no CDSC.
• Many fund companies convert Class B shares to Class A shares once the CDSC period ends.

Suitability

• Class B shares are generally suitable for intermediate- to long-term investors investing smaller amounts.
• Investors with larger amounts to invest often benefit more from Class A shares because breakpoint schedules can reduce the front-end load.

Sidenote — Class A vs. B for long-term investors

It can be hard to tell whether Class A or B suits a long-term investor. The general rule:

Class A - suitable for long-term investors with large amounts to invest Class B - suitable for long-term investors with small amounts to invest

Class B shares often look like the better choice: held past the CDSC period, they carry no front or back-end load. The Summit Utilities Fund example shows why Class A can still win.

Summit Utilities Fund — fee structures:

Summit Utilities Fund Class A Shares

Breakpoint schedule:

Sales charge	Volume
5.50%	$0 - $49,999
4.50%	$50,000 - $99,999
3.50%	$100,000 - $249,999
2.50%	$250,000 - $499,999
1.50%	$500,000 - $999,999
0.00%	$1,000,000+

0.25% 12b-1 fees (annual)

Summit Utilities Fund Class B Shares

Contingent deferred sales charge schedule:

CDSC	Years
5.00%	1 year
4.00%	2 years
4.00%	3 years
3.00%	4 years
2.00%	5 years
1.00%	6 years
0.00%	7 years

1.00% 12b-1 fees (annual)

🔑 The worked comparison:

Say an investor plans to hold shares for eight years and has $750,000 to invest. Which share class costs less?

Class A shares. The $750,000 purchase sits in the $500,000 - $999,999 tier, so the investor pays a 1.50% front-end load plus an annual 0.25% 12b-1 fee. Ignoring compounding, the total is 3.50% (1.50% front-end load + 0.25% × 8 years).

With Class B shares the investor would pay 8.00% in fees even with no back-end load (1.00% 12b-1 × 8 years). If the Class B shares converted to Class A after the 7-year CDSC period, the total would still be 7.25% (1.00% × 7 years + 0.25% × 1 year).

Apart from the sales charge structure, the big difference between the two classes is the 12b-1 fee. That is why a long-term investor with a large amount to invest does better paying a front-end load than choosing Class B, even without a CDSC.

Class C shares (level load)

• Class C shares are best known for ongoing marketing fees, which create a level load (a continuing cost rather than a one-time sales charge).
• This share class typically does not impose a front-end or back-end sales charge, although some Class C shares impose a one-year CDSC. With that structure, investors avoid the back-end charge if they hold the shares for at least one year.
• The most significant expense for Class C shares is typically 12b-1 fees — a marketing fee intended to lower a fund’s expense ratio by attracting more investors.

Why 12b-1 fees exist

Many mutual funds have operating expenses that barely move as assets grow. Say a fund has $80 million in assets and $1.2 million in annual operating expenses, an expense ratio of 1.5%. If the fund doubled its assets to $160 million while expenses stayed at $1.2 million, the expense ratio would fall to 0.75%.

🔑 12b-1 fee components

12b-1 fees are used to grow a fund’s assets in hopes of lowering expenses on a per-investor basis. There are two components:

12b-1 fees by share class

“No load” marketing rule

Regulators recognize that ongoing 12b-1 fees can reduce investor returns over time. Because of that, a fund charging more than 0.25% in 12b-1 fees cannot market itself as a “no load” fund. Otherwise, an investor might buy a fund expecting low costs while paying an ongoing marketing fee that doesn’t go away. So even if many Class C shares don’t have a front-end or back-end sales charge, they generally can’t be marketed as “no-load” due to their higher 12b-1 fees.

Sidenote — 12b-1 fee impact on loads

Funds assessing the maximum 12b-1 fee (1%) cannot also impose the maximum 8.5% on front or back-end loads. Instead, the maximum possible load is reduced to 7.25%. The regulators impose this rule to ensure investors are not subject to extraordinary fee schedules.

Suitability

• Class C shares are generally suitable for short-term investors. Because 12b-1 fees continue year after year, long-term investors typically want to avoid this share class.
• Even though a 1% annual fee may sound small, it’s charged repeatedly. If an investor holds Class C shares for ten years, they will pay the 1% annual fee ten times!*

*Technically, 12b-1 fees are assessed quarterly, although the fee is expressed as an annual percentage. For example, assume an investor owes an annual 12b-1 fee of $100. The fund would charge $25 per quarter instead of a one-time $100 fee.
