What Are Clean Shares?

Clean shares refer to a class of mutual fund shares that are stripped of embedded commissions, revenue-sharing agreements, or other forms of compensation to intermediaries such as brokers or financial advisors. These shares are designed to be transparent and cost-efficient, primarily serving investors who either work with fee-only advisors or who invest independently. Clean shares emerged in response to regulatory pressure and growing demand for increased transparency in mutual fund pricing structures.

The concept became more widely discussed in the financial services industry after the U.S. Department of Labor’s 2016 fiduciary rule proposal, which pushed for clearer disclosures and the elimination of conflicts of interest in retirement account recommendations. Although parts of the rule were later vacated, the attention it brought to hidden compensation structures encouraged the development of cleaner share classes.

How Clean Shares Work

Unlike traditional mutual fund share classes—which may carry front-end sales loads (Class A), deferred sales charges (Class B), or level commissions (Class C)—clean shares eliminate these costs. Instead, investors pay fees directly to their advisor, often in the form of an ongoing asset-based advisory fee. This separation of product and compensation structure allows for better alignment between the investor and advisor.

Clean shares still include a fund’s internal expenses, such as management fees, administrative costs, and other operating expenses. However, they exclude distribution and servicing fees, such as 12b-1 fees, which are commonly found in other share classes. Because these costs are stripped out, clean shares generally offer a lower expense ratio than their commission-based counterparts.

Benefits of Clean Shares

Clean shares are intended to reduce conflicts of interest by removing sales-based incentives. In a traditional commission model, an advisor might have financial motivation to recommend a fund that pays them a higher commission or revenue share. Clean shares neutralize this concern by requiring compensation to come directly from the client, typically through a fee-based advisory agreement.

This model also makes it easier to compare investment options on an apples-to-apples basis. With fewer embedded costs, the true cost of the investment is more transparent, helping investors and advisors make decisions based on fund performance, strategy, and suitability rather than sales incentives.

Additionally, clean shares can be more cost-effective over time. Investors who plan to hold mutual fund investments for the long term often benefit from lower internal fund expenses, especially when compared to C shares or other share classes that layer on recurring distribution fees.

Considerations and Limitations

While clean shares promote cost transparency, they may not be the most appropriate option for every investor. For example, individuals who prefer a transactional relationship with an advisor—where advice is provided at the point of sale and compensated through a commission—might find traditional share classes more suitable, especially if they invest infrequently and the commissions are lower than ongoing advisory fees.

Another consideration is availability. As of now, not all mutual fund providers offer clean share classes across their fund lineups. Even when they do, clean shares may not be available on every investment platform or brokerage, depending on whether agreements have been established to support them.

Operational complexity can also be a barrier. Clean shares often require changes to billing systems, recordkeeping, and compliance oversight, which can slow their adoption across the industry. Broker-dealers in particular may be hesitant to transition fully to clean share models without a clear structure for collecting advisory fees.

Regulatory Context

Regulators have supported clean shares as part of a broader effort to improve fiduciary practices and transparency in the investment industry. The Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA) have both provided guidance on the use and marketing of clean shares.

FINRA’s Regulatory Notice 17-15, issued in 2017, clarified how clean shares can be used in brokerage accounts and addressed concerns related to fair compensation and disclosures. Although the fiduciary rule was ultimately vacated by a federal court, the regulatory momentum helped cement clean shares as a viable option for fee-based advisory practices.

The Bottom Line

Clean shares offer a more transparent pricing model for mutual fund investments by removing embedded commissions and intermediary compensation. They align well with fee-only advisory models and can result in lower overall costs for investors. However, they are not universally available and may not fit every investor’s needs or preferences. As the investment industry continues to evolve toward more transparent and client-centric models, clean shares are likely to remain an important tool for advisory firms and investors seeking clear cost structures.
