Vanguard to change target benchmarks for 22 index funds

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 Vanguard’s ‘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 industry’s 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 firm’s 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 world’s 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 Vanguard’s move to the new benchmarks, FTSE will become the third-largest equity
exchange-traded index benchmark provider globally.

“Today’s 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 CRSP’s broadly diversified
benchmarks that cover the broad U.S. market, market capitalization segments, and styles.

CRSP’s 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 Vanguard’s 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
Poor’s benchmarks, or the 11 Vanguard sector equity funds currently seeking to track MSCI
benchmarks.

The benchmarks for Vanguard’s 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.
