The changes are expected to eventually lead to fee reductions for investors in Vanguard funds holding $537 billion, or more than a quarter of the $1.95 trillion that the company manages in U.S. mutual funds and exchange-traded funds.
The benchmark changes affect all share classes for the 22 funds, including shares available to average investors, as well as those geared toward institutional investors, such as companies offering 401(k) plans. Also affected are Vanguard's ETF share classes of each fund.
