Understanding Mutual Fund Share Classes & Interclass Exchanges

When investing in mutual funds, you might notice that there are different share classes available—and knowing the difference can have a meaningful impact on your long-term returns. At Fiat Wealth Management, we help our clients make sense of these options, including the potential benefits of something called an interclass exchange.

What is an Interclass Exchange? And Why Should You Care?

Simply put, an interclass exchange allows you to transfer your investment from one share class of a mutual fund to another within the same fund family. Each share class has its own fee structure, sales charges, and expense ratios—differences that can significantly impact your bottom line over time. The good news? If done correctly, an interclass exchange is not a taxable event!

Example: The Growth Fund of America®

One of the most popular mutual funds, The Growth Fund of America® by American Funds, has a total of $310 billion in assets and offers 19 different share classes. While most are designed for retirement plans and 529 college savings plans, some are available for purchase or exchange through financial institutions.

Below is a list of the available share classes accessible to advisors at most institutions (as of 02/20/25):

Why Do Different Share Classes Exist?

You may be wondering why the same investment has multiple share classes. Here’s a breakdown of the key differences:

Fund Types Above:

  • Class A Shares – Front-end sales charge & annual expenses.
  • Class F Shares (F-1, F-2, F-3) – For fee-based advisory platforms; no sales loads, lower expenses, and a separate advisory fee.

Other Fund Types:

  • Class B Shares – No upfront cost, but higher ongoing fees and a deferred sales charge if sold early; often convert to Class A over time.
  • Class C Shares – No front-end load, higher annual expenses, and may have a small exit fee.

The Bottom Line

The goal of an interclass exchange is to secure the fund’s lowest available expense ratio while factoring in other costs, such as transaction fees. For example, exchanging to the F-3 share class might be a smart move if another share class is currently held.

It’s also important to note that, as of February 20, 2025, interclass exchanges are non-taxable events, though they may involve transaction costs. At Fiat Wealth Management, we carefully evaluate these costs as part of an overall cost-benefit analysis.
