VALLEY FORGE, PA (October 2, 2012)Vanguard plans to transition six international stock index

funds to FTSE benchmarks and 16 U.S. stock and balanced index funds to new benchmarks developed

by the University of Chicago’s Center for Research in Security Prices (CRSP). The transition from the

current MSCI benchmarks for the 22 funds is expected to result in considerable savings for the funds

shareholders over time.

The indexes from FTSE and CRSP are well constructed, offer comprehensive coverage of their

respective markets, and meet Vanguards best practice standards for market benchmarks, said

Vanguard Chief Investment Officer Gus Sauter. Equally important, and with our clients best interests

in mind, we negotiated licensing agreements for these benchmarks that we expect will enable us to

deliver significant value to our index fund and ETF shareholders and lower expense ratios over time. In

an environment in which index licensing fees, in general, have represented a growing portion of the

expenses that investors pay to own index funds and ETFs, Mr. Sauter noted that the long-term

agreements with FTSE and CRSP will provide cost certainty going forward with these two index

providers.

Vanguard is the mutual fund industrys only client-owned firm that manages its funds and ETFs

at cost*, said Mr. Sauter. Our structure, along with our ongoing commitment to keep operating costs at

the lowest reasonable levels, leads to low expenses that are enduring in nature.

Vanguard pioneered the first index mutual fund for individual investors in 1976 with the

introduction of Vanguard 500 Index Fund and has continually sought and contributed to improvements

and innovations in benchmark construction. During his 25-year career, Mr. Sauter has been in the

forefront of cutting-edge index construction methodology. For instance, in 2003, Vanguard was the first

to adopt benchmarks incorporating objective rules, float-adjustment, and overlapping market

capitalization buffer zones that are now standard in the mutual fund industry.

FTSE: A Global Index Leader

Vanguard has used FTSE indexes since 2003 and now employs the firms benchmarks for more

than 20 index portfolios around the world, representing $26 billion in aggregate assets. Vanguard is

very pleased to expand our deep relationship with FTSE and looks forward to adopting its benchmarks

for our largest and most widely held international funds and ETFs, said Mr. Sauter. The benchmarks

offer comprehensive and diversified coverage of the international developed and emerging markets.

Six Vanguard international index funds with aggregate assets of $170 billion will transition to

benchmarks in the FTSE Global Equity Index Series, including the $67 billion Vanguard Emerging

Markets Stock Index Fund. This fund and its ETF Shares (ticker: VWO), the worlds largest emerging

markets ETF (source: Strategic Insight, as of 7/31/12), will move from the MSCI Emerging Markets

Index to the FTSE Emerging Index. While the two indexes are generally comparable, the FTSE

Emerging Index classifies South Korea as a developed market.

With Vanguards move to the new benchmarks, FTSE will become the third-largest equity

exchange-traded index benchmark provider globally.

Todays agreement with Vanguard represents another significant step forward in building our

presence in North America and in making FTSE a household name in the marketplace, said Mark

Makepeace, chief executive of FTSE. Our strategy for the FTSE brand is a global one, and we are

committed to building long-term, sustainable relationships with all of our clients globally to bring real

value to investors.

CRSP: An Index Innovator

CRSP is one of 11 research centers at the University of Chicago Booth School of Business. The

research organization pioneered the development of U.S. stock market data in 1960 that are widely

used in academic and investment research.

In 2009, CRSP engaged with Vanguard to create a new series of investable indexes, the CRSP

Indexes. Vanguard will be the first investment management firm to track CRSPs broadly diversified

benchmarks that cover the broad U.S. market, market capitalization segments, and styles.

CRSPs capitalization-weighted methodology introduces the unique concept of packeting,

which cushions the movement of stocks between adjacent indexes and allows holdings to be shared

between two indexes of the same family. This approach maximizes style purity while minimizing index

turnover.

CRSP is highly regarded and experienced in the creation of market databases, and its

innovative packeting methodology is expected to minimize transaction costs during periodic index

rebalancing, said Mr. Sauter.

Sixteen Vanguard stock and balanced index funds, with aggregate assets of $367 billion, will

track CRSP benchmarks, including Vanguards largest index fund, the $197 billion Vanguard Total

Stock Market Index Fund. The fund and its ETF Shares (ticker: VTI) will transition from the MSCI U.S.

Broad Market Index to the CRSP US Total Market Index.

For more than 50 years, CRSP has been providing research-quality market and index data.

The new CRSP Indexes are a logical extension of our core products and demonstrate not only our

innovative thinking, but also the depth of our commitment to positively influence practices in the

financial arena. The index licensing agreement we have entered into with Vanguard strongly validates

our efforts by one of the leading financial services providers in the world, said David Barclay, chief

operating officer of CRSP.

Additional Transition Details

The benchmark changes will encompass all share classes of the 22 funds, including ETFs. The

transitions will be staggered and are expected to occur collectively over a number of months. No

changes are planned for Vanguard U.S. stock index funds seeking to track Russell and Standard and

Poors benchmarks, or the 11 Vanguard sector equity funds currently seeking to track MSCI

benchmarks.

The benchmarks for Vanguards Target Retirement, LifeStrategy, and Managed Payout Funds

and other funds of funds will also change. The MSCI All Country World ex USA Investable Market Index

and MSCI US Broad Market Index components will be replaced by the FTSE Global All Cap ex US

Index and CRSP US Total Market Index. The asset allocations of the funds will not change.

The transition to the new benchmarks is not expected to result in capital gains distributions to

the funds shareholders, according to Vanguard analysis based on current market conditions. Each of

the index funds currently possesses realized capital losses, which can be used to offset any realized

gains. The transition will require some turnover of holdings and result in transaction costs. However,

Vanguard Equity Investment Group, manager of the index funds, will seek to minimize trading impact

through the use of efficient portfolio trading and other strategies developed over many years and used

during the periodic rebalancing of indexes.
