The SEC’s approval of a dual share class model for mutual funds paves the way for enhanced investment options, cost savings, and wider industry adoption, with industry players preparing for a transformative shift in fund structures.
The U.S. Securities and Exchange Commission (SEC) has initiated a transformative shift in the fund management landscape by approving exemptive relief that permits asset managers to offer a dual share class model for mutual funds, introducing exchange-traded fund (ETF) share classes alongside traditional mutual funds. This milestone opens a pathway for investors to benefit from expanded investment opportunities, potential cost savings, tax efficiencies, and broader distribution access.
Dimensional Fund Advisors (DFA) recently secured SEC approval to launch ETF share classes for 13 of its existing mutual funds, making it the first asset manager to do so since Vanguard’s patent on this structure expired in 2023. DFA’s move, announced in November 2025, is expected to roll out gradually starting in early 2026 and is widely viewed as a catalyst that could encourage other asset managers to pursue similar offerings. The Investment Company Institute and other industry advocates highlight that such hybrid fund structures can enable lower costs and improved tax efficiency for investors by streamlining operations and reducing duplicated expenses across share classes.
This regulatory progress aligns with a series of approvals by the SEC in late 2025, which authorised exchanges including NYSE Arca, Nasdaq, and Cboe BZX to list and trade ETFs operating as multi-class funds. These funds simultaneously offer both mutual fund and ETF share classes, providing investors with efficient portfolio management options and potential cost advantages. Nonetheless, the SEC underscored the necessity of safeguards to mitigate conflicts of interest and ensure operational transparency within these dual-structure funds.
Despite the opportunities presented by this model, operational complexities remain a critical challenge. Without automated systems to manage conversions between mutual fund and ETF share classes, asset managers and distributors could face increased manual workload and heightened risk of errors. Recognising this, the Depository Trust & Clearing Corporation (DTCC) has committed to enhancing its Fund/SERV platform to support automated share class conversions. The DTCC aims to begin industry testing by the first quarter of 2026 and launch by the second quarter, pending regulatory approvals. This advancement is intended to streamline processes, reduce manual handling, and improve settlement speed, thus facilitating the scalability of dual share class funds.
The emergence of these new structures follows the expiration of Vanguard’s 20-year patent on dual mutual fund-ETF share classes, which expired in May 2023. Since then, prominent players including Morgan Stanley and Fidelity have sought SEC clearance to offer similar products, reflecting growing interest in capturing the expanding ETF market. Cboe Global Markets, for example, filed for approval in April 2024 to enable issuers to add ETF share classes to existing mutual funds. While the SEC’s decision on this and other applications remains pending, the regulatory landscape is unmistakably moving toward acceptance of multi-class ETF mutual fund structures.
The SEC’s careful approach, balancing innovation with investor protection, reflects concerns about the complexities governing multi-class fund operations. Proposed rules released in October 2025 by the SEC provide a comprehensive framework addressing listing, disclosure, and conflict-of-interest safeguards to ensure that market transparency and fairness are maintained as these hybrid products become more widespread.
Overall, the unfolding regulatory approvals and industry adaptations signify a historic shift in how fund managers can structure, offer, and distribute their products. Investors stand to benefit from enhanced flexibility and cost efficiencies, while the market awaits further developments as technology solutions like DTCC’s automated conversion platform come online to support this new era in fund management.

- https://www.reuters.com/markets/wealth/sec-approves-dimensional-fund-advisors-launch-etf-share-class-13-mutual-funds-2025-11-17/ – On November 17, 2025, the U.S. Securities and Exchange Commission (SEC) approved Dimensional Fund Advisors (DFA) to introduce an exchange-traded fund (ETF) share class for 13 of its existing mutual funds. This marks a significant regulatory milestone, making DFA the first asset manager in over two decades to implement ETF share classes for mutual funds beyond Vanguard, which held a now-expired 20-year patent on the model. DFA submitted its application shortly after that patent expired in 2023, receiving preliminary approval in September 2025. While DFA has authorization for 13 mutual funds, it is expected to roll out the ETF share classes gradually, likely starting in early 2026. Industry advocates, including the Investment Company Institute, emphasize that this move could provide mutual fund investors with lower-cost and more tax-efficient access to investment strategies by consolidating operational costs across share classes. The development is considered a catalyst that may lead to the approval of similar applications by other asset managers seeking a presence in the expanding ETF market.

The rule change allows for the listing and trading of exchange-traded fund (ETF) shares that operate as a multi-class fund, offering both mutual fund and ETF share classes. The SEC noted that such a structure could provide benefits to investors, including more efficient portfolio management and cost efficiencies. However, the SEC also highlighted the need for appropriate safeguards to address potential conflicts and ensure transparency in the operation of multi-class ETF funds.

- https://www.reuters.com/business/finance/cboe-global-markets-seeks-sec-approval-list-etf-share-class-structure-2024-04-04/ – In April 2024, Cboe Global Markets requested the SEC to approve a rule change allowing issuers to add an exchange-traded fund (ETF) share class to existing mutual funds. If approved, this would enable asset managers to offer ETF exposure through current mutual fund portfolios, providing more investment options. The patent on the share class concept held by Vanguard Group expired in May 2023, and since then, several firms including Dimensional Fund Advisors, Morgan Stanley, and Fidelity have sought similar approvals. The SEC must decide on Cboe’s application within 240 days. Approval could significantly increase ETF numbers and assets. While approval chances are uncertain, Cboe’s involvement may enhance the long-term likelihood of obtaining the SEC’s endorsement.
