Class A, B & C Share Loads

Mutual funds with sales charges (loads) are typically grouped into share classes. The key difference is how and when the sales charge is collected.

🔑 Master comparison table — Class A vs. B vs. C (guaranteed exam topic)

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 (verbatim)

ABC Fund Class A Breakpoint Charge

Volume	Sales Charge
$0 - $24,999	8.5%
$25,000 - $49,999	7.0%
$50,000 - $99,999	5.5%
$100,000+	4.0%

• 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 (verbatim):

Using the breakpoint schedule above, assume a customer has $20,000 to invest. They could sign a $5,000 LOI, pledging to invest the additional $5,000 within the next 13 months. That would qualify them for the 7.0% sales charge today (instead of 8.5%).

Backdating (verbatim):

LOIs can also be backdated up to three months to include prior purchases. For example, if the investor had purchased $1,000 a few weeks before investing the $20,000, they could reduce the LOI amount to $4,000.

Backdating does not extend the LOI period. If an LOI is backdated three months, the investor has only ten months remaining to complete the shortfall deposit. If the investor fails to complete the deposit, 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 $24,000 in the ABC fund, the registered representative must explain how the customer could qualify for the next breakpoint (they’re only $1,000 away). The customer’s options include:

Investing the additional $1,000 now Signing an LOI for the $1,000 shortfall Doing nothing and accepting the higher sales charge

The incentive math (verbatim):

There can be an incentive for a financial professional to avoid helping a customer reach a breakpoint, because the firm earns more when the sales charge is higher. Using the same schedule:

Sales charge if customer purchases $24,000 and pays a 8.5% sales charge = $2,040 Sales charge if customer purchases $25,000 and pays a 7.0% sales charge = $1,750

That’s a $290 difference. If the representative fails to notify the customer about the breakpoint opportunity, it’s a violation called a breakpoint sale. Breakpoint sales are subject to regulator-imposed fines and/or suspensions. The representative must act as a fiduciary by putting the customer’s interests ahead of their own.

Who gets breakpoints

Sidenote — Investment clubs (verbatim):

Investment clubs are groups of friends or colleagues that pool their money together for investment purposes. Think of them as joint investment accounts for people with similar interests and backgrounds. Investment clubs are not granted breakpoints and are assessed 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 $10,000 of the ABC Stock Fund, $10,000 of the ABC Corporate Bond Fund, and $5,000 of the ABC 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 (verbatim)

ABC Fund Class B CDSC Schedule

Years of ownership	Charge
1 year	8%
2 years	6%
3 years	4%
4 years	2%
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

Sometimes, it’s difficult to determine whether Class A or B shares are suitable for a long-term investor. As we’ve discussed above, here are the generalities:

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

Furthering the confusion, Class B shares often seem like the better choice. If an investor holds their shares longer than the CDSC period, they pay no front or back-end load. So, why would an investor choose Class A shares? To better understand this concept, let’s look at an example.

MFS Utilities Fund — fee structures (verbatim):

MFS Utilities Fund Class A Shares

Breakpoint schedule:

Sales charge	Volume
5.75%	$0 - $49,999
4.75%	$50,000 - $99,999
3.75%	$100,000 - $249,999
2.75%	$250,000 - $499,999
2.00%	$500,000 - $999,999
0.00%	$1,000,000+

0.25% 12b-1 fees (annual)

MFS Utilities Fund Class B Shares

Contingent deferred sales charge schedule:

CDSC	Years
4.00%	1 year
4.00%	2 years
3.00%	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 (verbatim, every step and figure):

Let’s assume an investor plans to hold shares for ten years and has $500,000 to invest. Can you determine which share class is better?

The answer - Class A shares. With this share class, the investor will pay a 2.00% front-end load and an annual 0.25% 12b-1 fee. Without complicating things with compounding fees, let’s assume they’d pay 4.50% in fees (2.00% front-end load + 0.25% 12b-1 fees x 10 years).

If they had chosen the Class B shares instead, they’d pay 10.00% in fees, even with no back-end load (1.00% 12b-1 fees x 10 years). Additionally, if the Class B shares converted to Class A shares after the CDSC period (7 years), they still would pay 7.75% in fees (1.00% 12b-1 fees x 7 years + 0.25% 12b-1 fees x 3 years).

Besides the sales charge structure, the big difference between the two share classes is the 12b-1 fees. This is why a long-term investor with a large amount to invest will be better off paying a front-end load than choosing Class B shares (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 (verbatim example)

Many mutual funds have operating expenses that don’t change much as assets grow. For example, assume a fund has $100 million in assets and $1 million in annual operating expenses. At that level, the expense ratio is 1%. If the fund could double assets to $200 million while keeping operating expenses at $1 million, the expense ratio would fall to 0.50%.

🔑 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.
