Five Vanguard Index Funds Transition to CRSP Indexes

VALLEY FORGE, Pa.--()--Effective with the opening of trading at 9:30 a.m. Eastern time on January 31, 2013, five Vanguard funds will seek to track CRSP Indexes. The transition to the new benchmarks is part of Vanguard’s announcement in October 2012 that 22 stock and balanced index funds would begin tracking new indexes this year.

The five funds (see chart below) previously sought to track MSCI indexes.

Fund       New CRSP Index       Former MSCI Index
Vanguard Mega Cap Index Fund*       CRSP US Mega Cap Index       MSCI US Large Cap 300 Index
Vanguard Large-Cap Index Fund       CRSP US Large Cap Index       MSCI US Prime Market 750 Index
Vanguard Mid-Cap Index Fund       CRSP US Mid Cap Index       MSCI US Mid Cap 450 Index
Vanguard Small-Cap Index Fund       CRSP US Small Cap Index       MSCI US Small Cap 1750 Index
Vanguard Variable Insurance Fund’s Mid-Cap Index Portfolio       CRSP US Mid Cap Index       MSCI US Mid Cap 450 Index

*Previously Vanguard Mega Cap 300 Index Fund.

The stated expense ratio for each share class of the Small-Cap Index Fund has declined by six basis points because acquired fund fees and expenses (AFFE) related to business development companies (BDCs), which are excluded from CRSP Indexes, are no longer included. The projected expense ratios now range from 0.06% to 0.24%, depending on the share class (see chart below).

Small-Cap Index Fund   Projected Expense Ratios
    New   Former
Investor Shares   0.24%   0.30%
Admiral Shares   0.10%   0.16%
Institutional Shares   0.08%   0.14%
Signal Shares   0.10%   0.16%
Institutional Plus Shares   0.06%   0.12%
ETF Shares   0.10%   0.16%

The expense ratios for the other funds will remain the same because AFFE was not a component in the expense ratios.

In addition, Vanguard Mega Cap 300 Index Fund was renamed Vanguard Mega Cap Index Fund. Its two share classes are now named Mega Cap ETF and Mega Cap Index Fund Institutional.

CRSP’s broadly diversified, capitalization-weighted indexes meet Vanguard’s "best practice" standards for market benchmarks and will help enable the company to deliver significant value to index fund and ETF shareholders through lower expense ratios over time.

Vanguard’s benchmark changes have been embraced by investors. Since the October announcement, the 22 funds adopting new indexes have attracted significant inflows, including nearly 10% of Vanguard’s record-setting net new cash flow of $141 billion in 2012.
