Vanguard’s Move Toward ETF Share Classes
Today, Vanguard Group has joined a growing list of asset managers seeking SEC approval for trading fund-share classes tied to actively managed mutual funds. They’ve become part of a trend that includes more than 60 other firms, like BlackRock, State Street, and Fidelity, which have applied for hybrid share class structures over the last couple of years.
It’s interesting to note that Vanguard was a pioneer in this field. Twenty-four years ago, they introduced the ETF-as-a-share-class model, launching the Vanguard Total Stock Market ETF (VTI) on May 24, 2001, as a share class for the Vanguard Total Stock Market Index (VTSAX).
Back then, tax efficiency was a key concern for Vanguard. ETFs employ daily in-kind transactions, which allow them to track the underlying portfolio without incurring taxable events. Effectively managed ETFs can mitigate capital gains distributions by offsetting unrealized gains. Incorporating ETF share classes into mutual funds enables the funds to enjoy these tax-efficient trading advantages.
Vanguard used to restrict others from using the ETF share class model, but with the expiration of their patent in May 2023, they opened the door for more than 60 asset managers to seek SEC approval to blend mutual fund shares with ETF shares.
Currently, Vanguard’s application is limited to index-tracking funds. They requested an extension to actively managed funds, but the SEC turned them down. So, their latest applications are somewhat different from others, aiming specifically at applying the ETF share class to actively managed mutual funds without altering existing index funds.
Both Vanguard and its competitors are looking to adopt ETF share classes to lessen potential capital gains distributions and appeal to a broader range of investors. In recent years, actively managed mutual funds have experienced significant outflows, making it challenging for managers, who sometimes have to sell at high prices, resulting in capital gains. This puts a tax burden on investors, so anything that enhances post-tax returns makes these funds more enticing.
However, using ETF share classes isn’t without its drawbacks. In some rare situations, mutual fund share classes can generate capital gains that ETFs can’t effectively offset. In those cases, both share classes might end up distributing a portion of capital gains, though this has only occurred once in Vanguard’s history since the establishment of this structure.
Moreover, this approach doesn’t suit all mutual funds. Some active managers have limitations on maintaining their performance advantage. Unlike mutual funds that can close to new investments when they reach these limits, ETFs trade on exchanges and can’t simply refuse new money. Introducing an ETF share class could lead to a loss of flexibility.
Still, the potential benefits might outweigh the downsides. When appropriately applied to the right mutual funds and managed with care, the ETF share class could represent a significant advancement for investors.
