Dimensional Funds Seek SEC Nod for ETF-Mutual Fund Hybrid Setup
Published Date: 10/1/2025
Notice
Summary
Dimensional Fund Advisors and its related companies want permission to offer a new type of investment fund that combines exchange-traded shares (ETFs) with regular mutual fund shares in one package. This change would make it easier for investors to choose how they want to invest, with smoother operations and more flexibility. If approved, this could roll out soon, giving investors fresh options without extra costs or delays.
Analyzed Economic Effects
7 provisions identified: 5 benefits, 2 costs, 0 mixed.
Funds can offer ETF and mutual classes
Registered open-end funds advised by Dimensional may offer one class of exchange-traded shares (ETF Shares) and one or more non-exchange-traded mutual fund classes (Mutual Fund Shares) within the same fund (a "Multi-Class ETF Fund"). You could choose to hold either the ETF Shares or the Mutual Fund Shares for the same underlying strategy.
In-kind ETF trades may lower costs and taxes
The ETF Class may use in-kind creations and redemptions that applicants say can reduce portfolio transaction costs and increase tax efficiency, which could lower capital gains distributions for shareholders.
Monitoring and board oversight to guard against cross-subsidies
Funds must adopt an Initial Advisor Report, an Ongoing Monitoring Process with numeric thresholds, and Ongoing Advisor Reports; if thresholds are exceeded the Advisor must notify the board within 30 days and recommend remedies, and the board must evaluate the plan at least annually.
Mutual-to-ETF exchange privilege available
A Mutual Fund Class may offer an "Exchange Privilege" letting holders exchange Mutual Fund Shares for ETF Shares (newly issued ETF Shares). ETF shareholders generally will not be able to exchange back to Mutual Fund Shares except on termination or merger.
Different dividend timing affects reinvestment
Mutual Fund Shares and ETF Shares may have different declaration, record, and payment dates; ETF shareholders may receive cash dividends later and generally cannot reinvest them automatically for several days, which can leave ETF investors "out of the market" for the dividend amount.
Redemptions for ETF class can be delayed for foreign assets
The proposed order would permit ETF Shares that include foreign investments to delay payment of redemption proceeds for more than seven calendar days if local market holidays or extended foreign delivery cycles prevent timely delivery of the foreign investments included in the basket.
Enhanced investor disclosures required
Multi-Class ETF Funds must take specific disclosure steps, including separate prospectuses for ETF Shares and Mutual Fund Shares, prominent prospectus and website disclosures that each fund offers both classes, and clear notice that ETF Shares are listed on an exchange and not individually redeemable.
