WHY READING THIS PROSPECTUS IS IMPORTANT
This prospectus explains the objectives, risks, and strategies of certain
Vanguard index funds. To highlight terms and concepts important to mutual fund
investors, we have provided "Plain Talk(R)" explanations along the way. Reading
the prospectus will help you to decide which Funds, if any, are the right
investments for you. We suggest that you keep it for future reference.
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
OTHER CLASSES OF SHARES AND OTHER PROSPECTUSES
Vanguard currently offers nine U.S. stock index funds. Each of these funds,
other than Vanguard 500 Index Fund, issues two classes of shares: Institutional
Shares and Investor Shares. Institutional Shares are intended for persons
investing at least $10 million who generally do not require special employee
benefit services. For those wishing to invest at least $10 million in an S&P 500
index fund and who generally do not require special employee benefit services,
Vanguard offers the Vanguard Institutional Index Fund. This Fund issues
Institutional Shares for those investing less than $200 million, and
Institutional Plus Shares for those investing $200 million or more.
This prospectus describes the Institutional Shares offered by each of the
Vanguard U.S. Stock Index Funds (other than Vanguard 500 Index Fund, which does
not offer Institutional Shares), and the Institutional Shares and Institutional
Plus Shares offered by Vanguard Institutional Index Fund. If you are interested
in purchasing Investor Shares, please call Vanguard at 1-800-662-7447 (or
1-800-523-1036 if you will be purchasing through an employer-sponsored
retirement plan).
Note that the Funds' separate share classes have different expenses; as a
result, their investment performances will vary.

FUND PROFILE--VANGUARD(R) INSTITUTIONAL INDEX FUND INSTITUTIONAL AND
INSTITUTIONAL PLUS SHARES
The following profile summarizes key features of Vanguard Institutional Index
Fund Institutional and Institutional Plus Shares.
INVESTMENT OBJECTIVE
The Fund seeks to match the performance of a benchmark index that measures the
investment return of large-capitalization stocks.
INVESTMENT STRATEGIES
The Fund employs a passive management strategy designed to track the performance
of the Standard & Poor's 500 Index, which is dominated by the stocks of large
U.S. companies. The Fund attempts to replicate the target index by investing all
or substantially all of its assets in the stocks that comprise the Index. For a
description of the Fund's replication technique, please see "Indexing Methods"
under MORE ON THE FUNDS.
PRIMARY RISKS
- - THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN
A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG
PERIODS. Stock markets tend to move in cycles, with periods of rising
prices and periods of falling prices.
- - The Fund is also subject to investment style risk, which is the chance that
returns from large-capitalization stocks will trail returns from other
asset classes or the overall stock market. Large-capitalization stocks tend
to go through cycles of doing better--or worse--than the stock market in
general. These periods have, in the past, lasted for as long as several
years.
PERFORMANCE/RISK INFORMATION
The bar chart and table below provide an indication of the risk of investing in
the Fund. The bar chart shows the performance of the Fund's Institutional Shares
in each calendar year since the Fund's inception. The table shows how the Fund's
average annual total returns for one and five calendar years and since inception
(for Institutional Shares) and for one calendar year and since inception (for
Institutional Plus Shares) compare with those of the index that the Fund seeks
to track. Keep in mind that the Fund's past performance does not indicate how it
will perform in the future.

FUND PROFILE--VANGUARD(R) EXTENDED MARKET INDEX FUND INSTITUTIONAL SHARES
The following profile summarizes key features of Vanguard Extended Market Index
Fund Institutional Shares.
INVESTMENT OBJECTIVE
The Fund seeks to match the performance of a benchmark index that measures the
investment return of mid- and small-capitalization stocks.
INVESTMENT STRATEGIES
The Fund employs a passive management strategy designed to track the performance
of the Wilshire 4500 Completion Index, a broadly diversified index of stocks of
medium-size and small U.S. companies. The Wilshire 4500 Index contains all of
the U.S. common stocks regularly traded on the New York and American Stock
Exchanges and the Nasdaq over-the-counter market, except those stocks included
in the S&P 500 Index. The Fund invests all or substantially all of its assets in
a representative sample of the stocks that comprise the Index. For a description
of the Fund's sampling technique, please see "Indexing Methods" under MORE ON
THE FUNDS.
PRIMARY RISKS

A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG

prices and periods of falling prices.
- - The Fund is also subject to investment style risk, which is the chance that
returns from mid- or small-capitalization stocks will trail returns from
other asset classes or the overall stock market. Small- and mid-cap stocks
historically have been more volatile in price than the large-cap stocks
that dominate the S&P 500 Index, and perform differently than the overall
stock market.

FEES AND EXPENSES
The following table describes the fees and expenses you may pay if you buy and
hold Institutional Shares of the Fund. The expenses shown under Annual Fund
Operating Expenses are based upon those incurred in the fiscal year ended
December 31, 1999.
SHAREHOLDER FEES (fees paid directly from your investment)
Sales Charge (Load) Imposed on Purchases: None
Transaction Fee on Purchases: None*
Sales Charge (Load) Imposed on Reinvested Dividends: None

Exchange Fee: None
ANNUAL FUND OPERATING EXPENSES (expenses deducted from the
Fund's assets)
Management Expenses: 0.10%
12b-1 Distribution Fee: None
Other Expenses: 0.02%
TOTAL ANNUAL FUND OPERATING EXPENSES: 0.12%
*The Fund reserves the right to deduct a transaction fee from future
purchases of shares.
The following example is intended to help you compare the cost of investing
in the Fund with the cost of investing in other mutual funds. It illustrates the
hypothetical expenses that you would incur over various periods if you invest
$10,000 in the Fund. This example assumes that the Fund provides a return of 5%
a year, and that operating expenses remain the same. The results apply whether
or not you redeem your investment at the end of each period.

FUND PROFILE--VANGUARD(R) VALUE INDEX FUND INSTITUTIONAL SHARES
The following profile summarizes key features of Vanguard Value Index Fund
Institutional Shares.
INVESTMENT OBJECTIVE
The Fund seeks to match the performance of a benchmark index that measures the
investment return of large-capitalization value stocks.
INVESTMENT STRATEGIES
The Fund employs a passive management strategy designed to track the performance
of the Standard & Poor's 500/BARRA Value Index, which includes those stocks of
the S&P 500 Index with lower-than-average price/book ratios. The Fund attempts
to replicate the target index by investing all or substantially all of its
assets in the stocks that comprise the Index. For a description of the Fund's
replication technique, please see "Indexing Methods" under MORE ON THE FUNDS.
PRIMARY RISKS
- - THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN
A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG
PERIODS. Stock markets tend to move in cycles, with periods of rising
prices and periods of falling prices.
- - The Fund is also subject to investment style risk, which is the chance that
returns from large-capitalization value stocks will trail returns from
other asset classes or the overall stock market. Value stocks tend to go
through cycles of doing better--or worse--than the stock market in general.
These periods have, in the past, lasted for as long as several years.
PERFORMANCE/RISK INFORMATION
The bar chart and table below provide an indication of the risk of investing in
the Fund. The bar chart shows the Fund's performance in the one full calendar
year since inception of the Institutional class of shares. The table shows how
the Fund's average annual total returns for one calendar year and since
inception compare with those of the index that the Fund seeks to track. Keep in
mind that the Fund's past performance does not indicate how it will perform in
the future.

FUND PROFILE--VANGUARD(R) SMALL-CAP VALUE INDEX FUND INSTITUTIONAL SHARES
The following profile summarizes key features of Vanguard Small-Cap Value Index
Fund Institutional Shares.
INVESTMENT OBJECTIVE
The Fund seeks to match the performance of a benchmark index that measures the
investment return of small-capitalization value stocks.
INVESTMENT STRATEGIES
The Fund employs a passive management strategy designed to track the performance
of the Standard & Poor's SmallCap 600/BARRA Value Index, which includes those
stocks of the S&P SmallCap 600 Index with lower-than-average price/book ratios.
The Fund attempts to replicate the target index by investing all or
substantially all of its assets in the stocks that comprise the Index. For a
description of the Fund's replication technique, please see "Indexing Methods"

returns from small-capitalization value stocks will trail returns from
other asset classes or the overall stock market. Value stocks tend to go
through cycles of doing better--or worse--than the stock market in general.
In addition, small-cap stocks historically have been more volatile in price
than the large-cap stocks that dominate the S&P 500 Index, and perform
differently than the overall stock market.
PERFORMANCE/RISK INFORMATION
The bar chart and table below provide an indication of the risk of investing in
the Fund. Because calendar-year performance information is not yet available,
the information presented in the bar chart and table reflects the performance of
the Fund's Investor Shares (which are offered through a separate prospectus).
Performance information for the Institutional Shares would be substantially
similar, since both share classes represent the same portfolio of securities;
their returns differ only to the extent that the expenses of the two classes
differ.
The bar chart shows the performance of the Fund's Investor Shares in the
one full calendar year since inception of the Fund. The table shows how the
Fund's average annual total returns for one year and since inception (for the
Fund's Investor Shares) compare with those of the index that the Fund seeks to
track. Keep in mind that the Fund's past performance does not indicate how it

FUND PROFILE--VANGUARD(R) GROWTH INDEX FUND INSTITUTIONAL SHARES
The following profile summarizes key features of Vanguard Growth Index Fund
Institutional Shares.
INVESTMENT OBJECTIVE
The Fund seeks to match the performance of a benchmark index that measures the
investment return of large-capitalization growth stocks.
INVESTMENT STRATEGIES
The Fund employs a passive management strategy designed to track the performance
of the Standard & Poor's 500/BARRA Growth Index, which includes those stocks of

PRIMARY RISKS
THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN A
WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG PERIODS.
Stock markets tend to move in cycles, with periods of rising prices and periods
of falling prices. The Fund is also subject to:
- - Investment style risk, which is the chance that returns from
large-capitalization growth stocks will trail returns from other asset
classes or the overall stock market. Growth stocks tend to go through
cycles of doing better--or worse--than the stock market in general. These
periods have, in the past, lasted for as long as several years.
- - Nondiversification risk, which is the chance that the Fund's performance
could be hurt disproportionately by a decline in the price of just a few
stocks. This is because the Fund invests a greater percentage of its assets
in the stocks of fewer companies as compared with other mutual funds.

MORE ON THE FUNDS
The following sections discuss other important features of Vanguard
Institutional Index Fund and the Vanguard U.S. Stock Index Funds.
INDEXING METHODS
In seeking to track a particular index, a fund generally uses one of two methods
to select stocks.
Some index funds hold each stock found in their target indexes in about the
same proportions as represented in the indexes themselves. This is called a
"replication" method. For example, if 5% of the S&P 500 Index were made up of
the stock of a specific company, a fund tracking that index (such as the
Institutional Index Fund) would invest about 5% of its assets in that company.
The Institutional Index Fund and the Mid-Cap, Value, Small-Cap Value, Growth,
and Small-Cap Growth Index Funds employ the replication method of indexing.
Because it would be very expensive to buy and sell all of the stocks held
in certain indexes (the Wilshire 5000 Index, for example, included more than
7,000 stocks as of December 31, 1999), many funds tracking these larger indexes
use a "sampling" technique. At Vanguard, we use a sophisticated computer program
to select a representative sample of stocks from a Fund's target index that will
resemble the full index in terms of industry weightings, market capitalization,
price/earnings ratio, dividend yield, and other characteristics. For instance,
if 10% of the Wilshire 5000 Index were made up of utility stocks, the Total
Stock Market Index Fund would invest about 10% of its assets in some--but not
all--of those utility stocks. The particular utility stocks selected by the
Fund, as a group, would have investment characteristics similar to those of the
utility stocks in the Index. Although the Funds' adviser attempts to closely
track the performance of the index, there is no guarantee that securities
selected for a Fund will provide investment performance exactly matching that of
its target index. The Total Stock Market, Extended Market, and Small-Cap Index
Funds employ the sampling method of indexing.
Each Fund seeks to provide investment results that correspond to its target
index. The correlation between the performance of a Fund and its target index is
expected to be at least 95%. (A correlation of 100% would indicate perfect
correlation.)
The following table shows the number of stocks held by each of the Funds,
and the number of stocks in each Fund's target index, as of December 31, 1999.
- --------------------------------------------------------------------------------

PLAIN TALK ABOUT
GROWTH FUNDS AND VALUE FUNDS
Growth investing and value investing are two styles employed by stock fund
managers. Growth funds generally focus on companies believed to have
above-average potential for growth in revenue and earnings. Reflecting the
market's high expectations for superior growth, such stocks typically have low
dividend yields and above-average prices in relation to such measures as
revenue, earnings, and book value. Value funds generally emphasize stocks of
companies from which the market does not expect strong growth. The prices of
value stocks typically are below-average in comparison with such factors as
earnings and book value, and these stocks typically have above-average dividend
yields. Growth and value stocks have, in the past, produced similar long-term
returns, though each category has periods when it outperforms the other. In
general, growth funds appeal to investors who will accept more volatility in
hopes of a greater increase in share price. Growth funds also may appeal to
investors with taxable accounts who want a higher proportion of returns to come
as capital gains (which may be taxed at lower rates than dividend income). Value
funds, by contrast, are appropriate for investors who want some dividend income
and the potential for capital gains, but are less tolerant of share-price
fluctuations.
- --------------------------------------------------------------------------------
ADDITIONAL RISK INFORMATION
[FLAG] EACH FUND IS SUBJECT TO MARKET RISK, WHICH IS THE CHANCE THAT STOCK
PRICES OVERALL WILL DECLINE OVER SHORT OR EVEN LONG PERIODS. STOCK MARKETS
TEND TO MOVE IN CYCLES, WITH PERIODS OF RISING STOCK PRICES AND PERIODS OF
FALLING STOCK PRICES.
To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns for the U.S. stock market over various
periods as measured by the S&P 500 Index, which--in addition to being the target
index for the Institutional Index Fund--is a widely used barometer of stock
market activity. (Total returns consist of dividend income plus change in market
price.) Note that the returns shown do not include the costs of buying and
selling stocks or other expenses that a real-world investment portfolio would
incur. Note, also, that the gap between best and worst tends to narrow over the
long term.
- --------------------------------------------------------------------------------
U.S. STOCK MARKET RETURNS (1926-1999)
- --------------------------------------------------------------------------------
1 YEAR 5 YEARS 10 YEARS 20 YEARS
- --------------------------------------------------------------------------------
Best 54.2% 28.6% 19.9% 17.9%
Worst -43.1 -12.4 -0.9 3.1
Average 13.2 11.0 11.1 11.1
- --------------------------------------------------------------------------------
The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926
through 1999. You can see, for example, that while the average return on common
stocks for all of the 5-year periods was 11.0%, returns for individual 5-year
periods ranged from a -12.4% average (from 1928 through 1932) to 28.6% (from
1995 through 1999). These average returns reflect past performance on common
stocks; you should not regard them as an indication of future returns from
either the stock market as a whole or any Fund in particular.

Even indexes that are subsets of the S&P 500 Index--such as the S&P
500/BARRA Value Index and the S&P 500/BARRA Growth Index (the target indexes for
the Value and Growth Index Funds)--will not perform in the same way as the
broader S&P 500 Index. Historically, stocks of the S&P 500/BARRA Value Index
have been less volatile than the stocks found in the broader S&P 500 Index;
stocks of the S&P 500/BARRA Growth Index, on the other hand, have displayed
somewhat greater short-term volatility than the S&P 500 Index's stocks. However,
both value and growth stocks have the potential at times to be more volatile
than the broader market.
[FLAG] THE FUNDS ARE ALSO SUBJECT, IN VARYING DEGREES, TO INVESTMENT STYLE RISK,
WHICH IS THE CHANCE THAT RETURNS FROM A SPECIFIC TYPE OF STOCK (FOR
INSTANCE, SMALL-CAP OR VALUE) WILL TRAIL RETURNS FROM OTHER ASSET CLASSES
OR THE OVERALL STOCK MARKET. EACH TYPE OF STOCK TENDS TO GO THROUGH CYCLES
OF DOING BETTER--OR WORSE--THAN COMMON STOCKS IN GENERAL. THESE PERIODS
HAVE, IN THE PAST, LASTED FOR AS LONG AS SEVERAL YEARS.
RISK OF NONDIVERSIFICATION
[FLAG] As index funds, the Institutional Index Fund and the U.S. Stock Index
Funds each hold the largest stocks in their target indexes in approximately the
same percentages as those stocks are represented in their indexes. When a target
index becomes less diversified, a fund that tracks that index similarly becomes
less diversified. This has happened to the GROWTH INDEX FUND. Due to the rapid
appreciation of certain stocks in its target index, the Fund's top four
holdings, as of the date of this prospectus, represent more than 25% of its
total assets. By tracking its target index, the Fund technically has become
"nondiversified" under SEC standards, although it continues to hold more than
100 stock positions in a variety of market sectors. As the market values of the
Fund's largest holdings rise and fall, there may be times when the Fund is
diversified under SEC standards and other times when it is not. Shareholders in
Vanguard Growth Index Fund are subject to the risk that the Fund's performance
could be hurt disproportionately by a decline in the price of just a few stocks.
In the unlikely event that the target index of any of the other Vanguard
U.S. Stock Index Funds becomes dominated by just a few companies, shareholders
in that Fund would similarly be subject to the risk of nondiversification.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
LARGE-CAP, MID-CAP, AND SMALL-CAP STOCKS
Stocks of publicly traded companies--and mutual funds that hold these
stocks--can be classified by the companies' market value, or capitalization.
Market capitalization changes over time, and there is no "official" definition
of the boundaries of large-, mid-, and small-cap stocks. Vanguard generally
defines large-capitalization (large-cap) funds as those holding stocks of
companies whose outstanding shares have a market value exceeding $12 billion;
mid-cap funds as those holding stocks of companies with a market value between
$1 billion and $12 billion; and small-cap funds as those typically holding
stocks of companies with a market value of less than $1 billion. Vanguard
periodically reassesses these classifications.
- --------------------------------------------------------------------------------
<PAGE>
31
TRANSACTION FEES
Some of Vanguard's index funds charge a transaction fee on purchases of fund
shares to offset the higher costs of trading certain securities, particularly
small-company stocks. The transaction fee ensures that these higher costs are
borne by the investors making the transactions--and not by shareholders already
in the fund who do not generate the costs. All transaction fees are paid
directly into the fund itself (unlike a sales charge or load that non-Vanguard
funds may impose to compensate their sales representatives). Without transaction
fees, some index funds would have trouble tracking their target indexes.
COSTS AND MARKET-TIMING
Some investors try to profit from a strategy called market-timing--switching
money into investments when they expect prices to rise, and taking money out
when they expect prices to fall. As money is shifted in and out, a fund incurs
expenses for buying and selling securities. These costs are borne by all fund
shareholders, including the long-term investors who do not generate the costs.
Therefore, the Institutional Index Fund and the U.S. Stock Index Funds have
adopted the following policies, among others, designed to discourage short-term
trading:
- - Each Fund reserves the right to reject any purchase request--including
exchanges from other Vanguard funds--that it regards as disruptive to the
efficient management of the Fund. A purchase request could be rejected
because of the timing of the investment or because of a history of
excessive trading by the investor.
- - Two of the Funds (Small-Cap Value and Small-Cap Growth) charge a
transaction fee on purchases. The other Funds reserve the right to impose
such a fee on selected purchases.
- - There is a limit on the number of times you can exchange into and out of a
Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD section).
- - Telephone and online exchanges are not permitted for non-IRA accounts.
THE VANGUARD FUNDS DO NOT PERMIT MARKET-TIMING. DO NOT INVEST IN THESE
FUNDS IF YOU ARE A MARKET-TIMER.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
THE COSTS OF INVESTING
Costs are an important consideration in choosing a mutual fund. That's because
you, as a shareholder, pay the costs of operating a fund, plus any transaction
costs associated with the fund's buying and selling of securities. These costs
can erode a substantial portion of the gross income or capital appreciation a
fund achieves. Even seemingly small differences in fund expenses can, over time,
have a dramatic effect on a fund's performance.
- --------------------------------------------------------------------------------
TURNOVER RATE
Generally, a passively managed fund sells securities only to respond to
redemption requests or to adjust the number of shares held to reflect a change
in the fund's target index. Turnover rates for large-cap stock index funds tend
to be very low because large-cap indexes, such as the S&P 500, typically do not
change much from year to year. Turnover rates for mid-cap and small-cap stock
index funds tend to be higher (although still relatively low, compared to
actively managed stock funds), because the indexes they track are more likely to
change as a result of mergers, acquisitions, business failures, or growth of
companies than a larger-cap index. The turnover rate of each Fund for each of
the last five years (or
<PAGE>
32
since inception of the applicable share class, if shorter) is shown in the
FINANCIAL HIGHLIGHTS section of this prospectus.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
TURNOVER RATE
Before investing in a mutual fund, you should review its turnover rate. This
gives an indication of how transaction costs could affect the fund's future
returns. In general, the greater the volume of buying and selling by the fund,
the greater the impact that brokerage commissions and other transaction costs
will have on its return. Also, funds with high turnover rates may be more likely
to generate capital gains that must be distributed to shareholders as income
subject to taxes. As of December 31, 1999, the average turnover rate for
passively managed domestic equity index funds investing in common stocks was
approximately 18%; for all domestic stock funds, the average turnover rate was
approximately 89%, according to Morningstar, Inc. (A turnover rate of 100% would
occur, for example, if a fund sold and replaced securities valued at 100% of its
net assets within a one-year period.)
- --------------------------------------------------------------------------------
INVESTMENT POLICIES
Each Fund reserves the right to substitute a different index for the index it
currently tracks if the current index is discontinued, or for any other reason
determined in good faith by the Fund's Board of Trustees. In every such
instance, the substitute index will measure the same general market (large-,
mid-, or small-cap, growth, or value) as the current index.
Each Fund may invest in foreign securities to the extent necessary to carry
out its investment strategy of holding all, or a representative sample, of the
stocks that comprise the index it tracks. It is not expected that any Fund will
invest more than 5% of its assets in foreign securities.
Although index funds, by their nature, tend to be tax-efficient investment
vehicles, the Funds generally are managed without regard to tax ramifications.
To track their target indexes as closely as possible, the Funds attempt to
remain fully invested (at least 95% of total assets) in the stocks of the index.
To help stay fully invested, and to reduce transaction costs, the Funds may
invest, to a limited extent, in futures and options contracts, warrants,
convertible securities, and swap agreements, which are types of derivatives.
Losses (or gains) involving futures can sometimes be substantial--in part
because a relatively small price movement in a futures contract may result in an
immediate and substantial loss (or gain) for a fund. Similar risks exist for
warrants (securities that permit their owners to purchase a specific number of
stock shares at a predetermined price), convertible securities (securities that
may be exchanged for another asset), and swap agreements (contracts in which
each party agrees to make payments to the other based on the return of a
specified index or asset).
For this reason, the Funds will not use futures, options, warrants,
convertible securities, or swap agreements for speculative purposes or as
leveraged investments that magnify the gains or losses of an investment. A
Fund's obligation under futures contracts will not exceed 20% of that Fund's
total assets.
The reasons for which a Fund will invest in futures and options are:
- - To keep cash on hand to meet shareholder redemptions or other needs while
simulating full investment in stocks.
<PAGE>
33
- - To reduce the Fund's transaction costs or add value when these instruments
are favorably priced.
THE FUNDS AND VANGUARD
Vanguard U.S. Stock Index Funds are members of The Vanguard Group, a family of
more than 35 investment companies with more than 100 funds holding assets worth
more than $550 billion.* All of the funds that are members of The Vanguard Group
share in the expenses associated with business operations, such as personnel,
office space, equipment, and advertising.
Vanguard also provides marketing services to the member funds. Although
shareholders do not pay sales commissions or 12b-1 distribution fees, each fund
pays its allocated share of The Vanguard Group's marketing costs.
*Vanguard Institutional Index Fund is not a member of The Vanguard Group, but is
administered by Vanguard and pays Vanguard a fee to provide management,
advisory, marketing, and other services.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
VANGUARD'S UNIQUE CORPORATE STRUCTURE
The Vanguard Group is truly a MUTUAL mutual fund company. It is owned jointly by
the funds it oversees and thus indirectly by the shareholders in those funds.
Most other mutual funds are operated by for-profit management companies that may
be owned by one person, by a group of individuals, or by investors who own the
management company's stock. By contrast, Vanguard provides its services on an
"at-cost" basis, and the funds' expense ratios reflect only these costs. No
separate management company reaps profits or absorbs losses from operating the
funds.
- --------------------------------------------------------------------------------
INVESTMENT ADVISER
The Vanguard Group (Vanguard), P.O. Box 2600, Valley Forge, PA 19482, founded in
1975, serves as the Funds' adviser through its Core Management Group. As of
December 31, 1999, Vanguard served as adviser for about $371.4 billion in
assets.
Under the terms of a service and advisory agreement, Vanguard pays for all
of the Institutional Index Fund's expenses (except taxes and brokerage
commissions). In turn, the Fund pays Vanguard a monthly management fee based on
an annual rate of 0.06% of the average daily net assets of the Institutional
Shares and 0.025% of the average daily net assets of the Institutional Plus
Shares. Vanguard manages the other Funds on an at-cost basis, subject to the
control of the Trustees and officers of the Funds.
For the fiscal year ended December 31, 1999, the investment advisory
expenses for the Institutional Share classes of the U.S. Stock Index Funds
represented an effective annual rate of approximately 0.01% of each Fund's
average net assets.
The Funds have authorized Vanguard to choose brokers or dealers to handle
the purchase and sale of securities for the Funds, and to get the best available
price and most favorable execution from these brokers with respect to all
transactions. The Funds may direct Vanguard to use a particular broker for
certain transactions in exchange for commission rebates or research services
provided to the Funds.

- --------------------------------------------------------------------------------
DIVIDENDS, CAPITAL GAINS, AND TAXES
FUND DISTRIBUTIONS
Each Fund distributes to shareholders virtually all of its net income (interest
and dividends, less expenses), as well as any capital gains realized from the
sale of its holdings. Income dividends for the Institutional Index Fund
(Institutional and Institutional Plus Shares) and the Total Stock Market, Value,
and Growth Index Funds generally are distributed in March, June, September, and
December; income dividends for the Extended Market, Mid-Cap, Small-Cap,
Small-Cap Value, and Small-Cap Growth Index Funds generally are distributed in
December. Capital gains distributions generally occur in December. In addition,
the Funds may occasionally be required to make supplemental dividend or capital
gains distributions at some other time during the year. You can receive
distributions of income dividends or capital gains in cash, or you can have them
automatically reinvested in more shares of the Fund.
BASIC TAX POINTS
Vanguard will send you a statement each year showing the tax status of all your
distributions. In addition, taxable investors should be aware of the following
basic tax points:
- - Distributions are taxable to you for federal income tax purposes whether or
not you reinvest these amounts in additional Fund shares.
- - Distributions declared in December--if paid to you by the end of
January--are taxable for federal income tax purposes as if received in
December.
- - Any dividends and short-term capital gains that you receive are taxable to
you as ordinary income for federal income tax purposes.
- - Any distributions of net long-term capital gains are taxable to you as
long-term capital gains for federal income tax purposes, no matter how long
you've owned shares in the Fund.
- - Capital gains distributions may vary considerably from year to year as a
result of the Funds' normal investment activities and cash flows.
- - A sale or exchange of Fund shares is a taxable event. This means that you
may have a capital gain to report as income, or a capital loss to report as
a deduction, when you complete your federal income tax return.
- - Dividend and capital gains distributions that you receive, as well as your
gains or losses from any sale or exchange of Fund shares, may be subject to
state and local income taxes.
<PAGE>
35
GENERAL INFORMATION
BACKUP WITHHOLDING. By law, Vanguard must withhold 31% of any taxable
distributions or redemptions from your account if you do not:
- - provide us with your correct taxpayer identification number;
- - certify that the taxpayer number is correct; and
- - confirm that you are not subject to backup withholding.
Similarly, Vanguard must withhold from your account if the IRS instructs us to
do so.
FOREIGN INVESTORS. The Vanguard funds generally do not offer their shares for
sale outside of the United States. Foreign investors should be aware that U.S.
withholding and estate taxes may apply to any investments in Vanguard funds.
INVALID ADDRESSES. If a dividend or capital gains distribution check mailed to
your address of record is returned as undeliverable, Vanguard will automatically
reinvest all future distributions until you provide us with a valid mailing
address.
TAX CONSEQUENCES. This prospectus provides general tax information only. If you
are investing through a tax-deferred retirement account, such as an IRA, special
tax rules apply. Please consult your tax adviser for detailed information about
a fund's tax consequences for you.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
DISTRIBUTIONS
As a shareholder, you are entitled to your share of the fund's income from
interest and dividends, and gains from the sale of investments. You receive such
earnings as either an income dividend or a capital gains distribution. Income
dividends come from both the dividends that the fund earns from its holdings and
the interest it receives from its money market and bond investments. Capital
gains are realized whenever the fund sells securities for higher prices than it
paid for them. These capital gains are either short-term or long-term, depending
on whether the fund held the securities for one year or less, or more than one
year.
- --------------------------------------------------------------------------------
SHARE PRICE
Each Fund's share price, called its net asset value, or NAV, is calculated each
business day after the close of regular trading on the New York Stock Exchange
(the NAV is not calculated on holidays or other days when the Exchange is
closed). Funds offering more than one class of shares compute a separate net
asset value for each share class. This is done by adding up the total value of
the Fund's investments and other assets attributed to each share class,
subtracting any of its liabilities (debts) attributed to each share class, and
then dividing by the number of Fund shares outstanding for each share class:
TOTAL ASSETS - LIABILITIES
NET ASSET VALUE = -------------------------------
NUMBER OF SHARES OUTSTANDING
Knowing the daily net asset value is useful to you as a shareholder because
it indicates the current value of your investment. The Fund's NAV, multiplied by
the number of shares you own, gives you the dollar amount you would have
received had you sold all of your shares back to the Fund that day.
A NOTE ON PRICING: A Fund's investments will be priced at their market
value when market quotations are readily available. When these quotations are
not readily available, invest-
<PAGE>
36
ments will be priced at their fair value, calculated according to procedures
adopted by the Funds' Board of Trustees.
Each Fund's share price can be found daily in the mutual fund listings of
most major newspapers under the heading "Vanguard Index Funds." Different
newspapers use different abbreviations for each Fund, but the most common are:
INSTIDX, INSTPLUS, TOTSTIST, EXTNDIST, MIDCPIST, SMCAPIST, VALUEIST, SMVALIST,
GRWTHIST, and SMGTHIST.
FINANCIAL HIGHLIGHTS
The following financial highlights tables are intended to help you understand
each Fund's financial performance for the past five years or since inception*,
and certain information reflects financial results for a single Fund share in
each case. The total returns in each table represent the rate that an investor
would have earned or lost each period on an investment in the Fund (assuming
reinvestment of all dividend and capital gains distributions). This information
has been derived from the financial statements audited by PricewaterhouseCoopers
LLP, independent accountants, whose report--along with the Funds' financial
statements--is included in the Institutional Index Fund's and the U.S. Stock
Index Funds' most recent annual reports to shareholders. You may have the annual
reports for the Institutional Index Fund and the U.S. Stock Index Funds sent to
you without charge by contacting Vanguard.
*Because the Small-Cap Growth Index Fund has not yet issued any Institutional
Shares, a financial highlights table is not included for this Fund.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE
This explanation uses the Institutional Index Fund Institutional Shares as an
example. The Fund began fiscal 1999 with a net asset value (price) of $112.85
per share. During the year, the Fund earned $1.501 per share from investment
income (interest and dividends) and $22.143 per share from investments that had
appreciated in value or that were sold for higher prices than the Fund paid for
them.
Shareholders received $2.474 per share in the form of dividend and capital gains
distributions. A portion of each year's distributions may come from the prior
year's income or capital gains.
The earnings ($23.644 per share) minus the distributions ($2.474 per share)
resulted in a share price of $134.02 at the end of the year. This was an
increase of $21.17 per share (from $112.85 at the beginning of the year to
$134.02 at the end of the year). For a shareholder who reinvested the
distributions in the purchase of more shares, the total return from the Fund was
21.17% for the year.
As of December 31, 1999, the Fund had $28.9 billion in net assets. For the year,
its expense ratio was 0.06% ($0.60 per $1,000 of net assets); and net investment
income amounted to 1.25% of its average net assets. It sold and replaced
securities valued at 14% of its net assets.

least seven days before you request your first exchange.
- --------------------------------------------------------------------------------
IMPORTANT NOTE: Once you have initiated a telephone transaction and a
confirmation number has been assigned, the transaction cannot be revoked. We
reserve the right to refuse any purchase request.
- --------------------------------------------------------------------------------
You can redeem (that is, sell or exchange) shares purchased by check at any
time. However, while your redemption request will be processed at the
next-determined net asset value after it is received, your redemption proceeds
will not be available until payment for your purchase is collected, which may
take up to ten calendar days.
- --------------------------------------------------------------------------------
A NOTE ON LARGE PURCHASES
It is important that you call Vanguard before you invest a large dollar amount.
It is our responsibility to consider the interests of all Fund shareholders, and
so we reserve the right to refuse any purchase that may disrupt the Fund's
operation or performance.
- --------------------------------------------------------------------------------
REDEEMING SHARES
This section describes how you can redeem--that is, sell or exchange--a Fund's
shares.
When Selling Shares:
- - Vanguard sends the redemption proceeds to you or a designated third party.*
- - You can sell all or part of your Fund shares at any time.
*May require a signature guarantee; see footnote on page 47.
When Exchanging Shares:
- - The redemption proceeds are used to purchase shares of a different Vanguard
fund.
- - You must meet the receiving fund's minimum investment requirements.
- - Vanguard reserves the right to revise or terminate the exchange privilege,
limit the amount of an exchange, or reject an exchange at any time, without
notice.
- - In order to exchange into an account with a different registration
(including a different name, address, or taxpayer identification number),
you must include the guaranteed signatures of all current account owners on
your written instructions.
In both cases, your transaction will be based on the Fund's next-determined
share price, subject to any special rules discussed in the "Redeeming Shares"
section of this prospectus.
- --------------------------------------------------------------------------------
NOTE: Once a redemption is initiated and a confirmation number given, the
transaction CANNOT be canceled.
- --------------------------------------------------------------------------------
<PAGE>
46
HOW TO REQUEST A REDEMPTION
You can request a redemption from your Fund account in one of two ways: by
telephone (sell, but not exchange), or by mail.
The Vanguard funds whose shares you cannot exchange by telephone are:
VANGUARD U.S. STOCK INDEX FUNDS, VANGUARD BALANCED INDEX FUND, VANGUARD
INTERNATIONAL STOCK INDEX FUNDS, VANGUARD REIT INDEX FUND, and VANGUARD GROWTH
AND INCOME FUND. These funds do, however, permit telephone exchanges within IRAs
and other retirement accounts.
- --------------------------------------------------------------------------------
TELEPHONE REQUESTS [TELEPHONE]
Call Vanguard Tele-Account 24 hours a day--or your assigned Service Associate
during business hours--to sell shares.
- --------------------------------------------------------------------------------
SPECIAL INFORMATION: We will automatically establish the telephone redemption
option for your account, unless you instruct us otherwise in writing. While
telephone redemption is easy and convenient, this account feature involves a
risk of loss from unauthorized or fraudulent transactions. Vanguard will take
reasonable precautions to protect your account from fraud. You should do the
same by keeping your account information private and immediately reviewing any
account statements that we send to you. Make sure to contact Vanguard
immediately about any transaction you believe to be unauthorized.
- --------------------------------------------------------------------------------
We reserve the right to refuse a telephone redemption if the caller is unable to
provide:
- - The ten-digit account number.
- - The name and address exactly as registered on the account.
- - The primary Social Security or employer identification number as registered
on the account.
- - The Personal Identification Number (PIN), if applicable (for instance,
Tele-Account).
Please note that Vanguard will not be responsible for any account losses
due to telephone fraud, so long as we have taken reasonable steps to verify the
caller's identity. If you wish to remove the telephone redemption feature from
your account, please notify us in writing.
- --------------------------------------------------------------------------------
A NOTE ON UNUSUAL CIRCUMSTANCES
Vanguard reserves the right to revise or terminate the telephone redemption
privilege at any time, without notice. In addition, Vanguard can stop selling
shares or postpone payment at times when the New York Stock Exchange is closed
or under any emergency circumstances as determined by the U.S. Securities and
Exchange Commission. If you experience difficulty making a telephone redemption
during periods of drastic economic or market change, you can send us your
request by regular or express mail. Follow the instructions on selling or
exchanging shares by mail in this section.
- --------------------------------------------------------------------------------
MAIL REQUESTS [ENVELOPE]
Send a letter of instruction signed by all registered account holders. Include
the fund name and account number and (if you are selling) a dollar amount or
number of shares OR (if you are exchanging) the name of the fund you want to
exchange into and a dollar amount or number of shares. To exchange into an
account with a different registration (including a different name, address,
taxpayer identification number, or account type), you must provide Vanguard with
written instructions that include the guaranteed signatures of all current
owners of the fund from which you wish to redeem.

- --------------------------------------------------------------------------------
A NOTE ON LARGE REDEMPTIONS
It is important that you call Vanguard before you redeem a large dollar amount.
It is our responsibility to consider the interests of all fund shareholders, and
so we reserve the right to delay delivery of your redemption proceeds--up to
seven days--if the amount may disrupt a Fund's operation or performance.
If you redeem more than $250,000 worth of Fund shares within any 90-day
period, the Fund reserves the right to pay part or all of the redemption
proceeds above $250,000 in-kind, i.e., in securities, rather than in cash. If
payment is made in-kind, you may incur brokerage commissions if you elect to
sell the securities for cash.
- --------------------------------------------------------------------------------
OPTIONS FOR REDEMPTION PROCEEDS
You may receive your redemption proceeds in one of two ways: check, or exchange
to another Vanguard fund.
- --------------------------------------------------------------------------------
CHECK REDEMPTIONS
Normally, Vanguard will mail your check within two business days of a
redemption.
- --------------------------------------------------------------------------------
EXCHANGE REDEMPTIONS
As described above, an exchange involves using the proceeds of your redemption
to purchase shares of another Vanguard fund.
- --------------------------------------------------------------------------------
FOR OUR MUTUAL PROTECTION
For your best interests and ours, Vanguard applies these additional requirements
to redemptions:
REQUEST IN "GOOD ORDER"
All redemption requests must be received by Vanguard in "good order." This means
that your request must include:
- - The Fund name and account number.
- - The amount of the transaction (in dollars or shares).
- - Signatures of all owners exactly as registered on the account (for mail
requests).
- - Signature guarantees (if required).*
- - Any supporting legal documentation that may be required.
- - Any outstanding certificates representing shares to be redeemed.
*For instance, a signature guarantee must be provided by all registered account
shareholders when redemption proceeds are to be sent to a different person or
address. A signature guarantee can be obtained from most commercial and savings
banks, credit unions, trust companies, or member firms of a U.S. stock
exchange.
TRANSACTIONS ARE PROCESSED AT THE NEXT-DETERMINED SHARE PRICE AFTER VANGUARD HAS
RECEIVED ALL REQUIRED INFORMATION.
- --------------------------------------------------------------------------------
LIMITS ON ACCOUNT ACTIVITY
Because excessive account transactions can disrupt management of the Fund and
increase the Fund's costs for all shareholders, Vanguard limits account activity
as follows:
- - You may make no more than TWO SUBSTANTIVE "ROUND TRIPS" THROUGH THE FUND
during any 12-month period.
<PAGE>
48
- - Your round trips through the Fund must be at least 30 days apart.
- - The Fund may refuse a share purchase at any time, for any reason.
- - Vanguard may revoke an investor's telephone exchange privilege at any time,
for any reason.
A "round trip" is a redemption from the Fund followed by a purchase back
into the Fund. Also, a "round trip" covers transactions accomplished by any
combination of methods, including transactions conducted by check, wire, or
exchange to/from another Vanguard fund. "Substantive" means a dollar amount that
Vanguard determines, in its sole discretion, could adversely affect the
management of the Fund.
- --------------------------------------------------------------------------------
ALL TRADES ARE FINAL
Vanguard will not cancel any transaction request (including any purchase or
redemption) that we believe to be authentic once the request has been initiated
and a confirmation number assigned.
- --------------------------------------------------------------------------------
UNCASHED CHECKS
Please cash your distribution or redemption checks promptly. Vanguard will not
pay interest on uncashed checks.
- --------------------------------------------------------------------------------
TRANSFERRING REGISTRATION
You can transfer the registration of your Fund shares to another owner by
completing a transfer form and sending it to Vanguard.
First-class mail to: Express or Registered mail to:
The Vanguard Group The Vanguard Group
P.O. Box 2900 100 Vanguard Boulevard
Valley Forge, PA 19482-2900 Malvern, PA 19355-2331
- --------------------------------------------------------------------------------
FUND AND ACCOUNT UPDATES
STATEMENTS AND REPORTS
We will send you account and tax statements to help you keep track of your Fund
account throughout the year as well as when you are preparing your income tax
returns.
In addition, you will receive financial reports about a Fund twice a year.
These comprehensive reports include an assessment of the Fund's performance (and
a comparison to its industry benchmark), an overview of the financial markets, a
report from the adviser, and the Fund's financial statements which include a
listing of the Fund's holdings.
To keep each Fund's costs as low as possible (so that you and other
shareholders can keep more of the Fund's investment earnings), Vanguard attempts
to eliminate duplicate mailings to the same address. When two or more Fund
shareholders have the same last name and address, we send just one Fund report
to that address--instead of mailing separate reports to each shareholder. If you
want us to send separate reports, notify our Institutional Division at
1-888-809-8102.
- --------------------------------------------------------------------------------
CONFIRMATION STATEMENT
Sent each time you buy, sell, or exchange shares; confirms the trade date and
the amount of your transaction.
- --------------------------------------------------------------------------------
<PAGE>
49
- --------------------------------------------------------------------------------
PORTFOLIO SUMMARY [BOOKLET]
Mailed quarterly for most accounts; shows the market value of your account at
the close of the statement period, as well as distributions, purchases, sales,
and exchanges for the current calendar year.
- --------------------------------------------------------------------------------
FUND FINANCIAL REPORTS
Mailed in February and August for all nine Funds.
- --------------------------------------------------------------------------------
TAX STATEMENTS
Generally mailed in January; report previous year's dividend and capital gains
distributions, proceeds from the sale of shares, and distributions from IRAs or
other retirement accounts.
- --------------------------------------------------------------------------------
MANDATORY CONVERSION TO INSTITUTIONAL OR INVESTOR SHARES
Vanguard Institutional Index Fund reserves the right to convert an investor's
Institutional Plus Shares into Institutional Shares of the Fund if the
investor's account balance falls below $200 million. In addition, the
Institutional Index Fund reserves the right to redeem an investor's
Institutional Shares if the investor's account balance falls below $10 million.
The Total Stock Market, Extended Market, Mid-Cap, Small-Cap, Value, Small-Cap
Value, Growth, and Small-Cap Growth Index Funds each reserve the right to
convert an investor's Institutional Shares into Investor Shares of the same Fund
if the investor's account balance falls below $10 million. Any such conversion
will be preceded by written notice to the investor. No transaction fee will be
imposed on share-class conversions.

GLOSSARY OF INVESTMENT TERMS
ACTIVE MANAGEMENT
An investment approach that seeks to exceed the average returns of the financial
markets. Active managers rely on research, market forecasts, and their own
judgment and experience in selecting securities to buy and sell.
CAPITAL GAINS DISTRIBUTION
Payment to mutual fund shareholders of gains realized on securities that a fund
has sold at a profit, minus any realized losses.
CASH RESERVES
Cash deposits, short-term bank deposits, and money market instruments which
include U.S. Treasury bills, bank certificates of deposit (CDs), repurchase
agreements, commercial paper, and banker's acceptances.
COMMON STOCK
A security representing ownership rights in a corporation. A stockholder is
entitled to share in the company's profits, some of which may be paid out as
dividends.
DIVIDEND INCOME
Payment to shareholders of income from interest or dividends generated by a
fund's investments.
EXPENSE RATIO
The percentage of a fund's average net assets used to pay its expenses. The
expense ratio includes management fees, administrative fees, and any 12b-1
distribution fees.
GROWTH STOCK FUND
A mutual fund that emphasizes stocks of companies believed to have above-average
prospects for growth. Reflecting market expectations for superior growth, these
stocks typically have low dividend yields and above-average prices in relation
to such factors as revenue, earnings, and book value.
INDEX
An unmanaged group of securities whose overall performance is used as a standard
to measure investment performance.
INVESTMENT ADVISER
An organization that makes the day-to-day decisions regarding a fund's

than outperform--a particular stock or bond market index. Also known as
indexing.
SECURITIES
Stocks, bonds, money market instruments, and interests in other investment

A percentage change, over a specified time period, in a mutual fund's net asset
value, with the ending net asset value adjusted to account for the reinvestment
of all distributions of dividends and capital gains.
VALUE STOCK FUND
A mutual fund that emphasizes stocks of companies whose growth prospects are
generally regarded as subpar by the market. Reflecting these market
expectations, the prices of value stocks typically are below-average in
comparison with such factors as earnings and book value, and these stocks
typically have above-average dividend yields.
VOLATILITY
The fluctuations in value of a mutual fund or other security. The greater a
fund's volatility, the wider the fluctuations between its high and low prices.

DESCRIPTION OF THE FUND
ORGANIZATION
The Fund was organized as a Pennsylvania business trust in 1990, and was
reorganized as a Delaware business trust in July, 1998. The Fund is registered
with the United States Securities and Exchange Commission (the Commission) under
the Investment Company Act of 1940 (the 1940 Act) as an open-end, diversified
management investment company. It currently offers the following fund and
classes of shares:
Vanguard Institutional Index Fund--
Institutional Shares and Institutional Plus Shares
The Fund has the ability to offer additional funds or classes of shares.
There is no limit on the number of full and fractional shares that the Fund may
issue for a single fund or class of shares.

CHARACTERISTICS OF THE FUND'S SHARES
RESTRICTIONS ON HOLDING OR DISPOSING OF SHARES. There are no restrictions
on the right of shareholders to retain or dispose of the Fund's shares, other
than the possible future termination of the Fund. The Fund may be terminated by
reorganization into another mutual fund or by liquidation and distribution of
the assets. Unless terminated by reorganization or liquidation, the Fund will
continue indefinitely.
SHAREHOLDER LIABILITY. The Fund is organized under Delaware law, which
provides that shareholders of a business trust are entitled to the same
limitations of personal liability as shareholders of a corporation organized
under Delaware law. Effectively, this means that a shareholder will not be
personally liable for payment of the Fund's debts except by reason of his or her
own conduct or acts. In addition, a shareholder could incur a financial loss on
account of a Fund obligation only if the Fund itself had no remaining assets
with which to meet such obligation. We believe that the possibility of such a
situation arising is extremely remote.
DIVIDEND RIGHTS. The shareholders of the Fund are entitled to receive any
dividends or other distributions declared by the Fund. No shares have priority
or preference over any other shares with respect to distributions. Distributions
will be made from the assets of the Fund, and will be paid ratably to all
shareholders of the Fund (or class) according to the number of shares of the
Fund (or class) held by shareholders on the record date. The amount of income
dividends per share may vary between separate share classes based upon
differences in the way that expenses are allocated between share classes
pursuant to the Fund's multiple class plan.
VOTING RIGHTS. The Fund's shareholders are entitled to vote on a matter if:
(i) a shareholder vote is required under the 1940 Act; (ii) the matter concerns
an amendment to the Declaration of Trust that would adversely affect to a
material degree the rights and preferences of the shares of any class or series;
or (iii) the Trustees determine that it is necessary or desirable to obtain a
shareholder vote. The 1940 Act requires a shareholder vote under various
circumstances, including to elect or remove Trustees upon the written request of
shareholders representing 10% or more of the Fund's net assets, and to change
any fundamental policy of the Fund. Shareholders of the Fund receive one vote
for each dollar of net asset value owned on the record date, and a fractional
vote for each fractional dollar of net asset value owned on the record date.
However, only the shares of the class affected by a particular matter are
entitled to vote on that matter. Voting rights are noncumulative and cannot be
modified without a majority vote.
LIQUIDATION RIGHTS. In the event of liquidation, shareholders will be
entitled to receive a pro rata share of the Fund's net assets.
PREEMPTIVE RIGHTS. There are no preemptive rights associated with shares of
the Fund.
CONVERSION RIGHTS. Shareholders of the Fund may convert their shares into
another class of shares of the same fund upon the satisfaction of any then
applicable eligibility requirements.
REDEMPTION PROVISIONS. The Fund's redemption provisions are described in
its current prospectus and elsewhere in this Statement of Additional
Information.
SINKING FUND PROVISIONS. The Fund has no sinking fund provisions.
CALLS OR ASSESSMENT. The Fund's shares, when issued, are fully paid and
non-assessable.
TAX STATUS OF THE FUND
The Fund intends to continue to qualify as a "regulated investment company"
under Subchapter M of the Internal Revenue Code. This special tax status means
that the Fund will not be liable for federal tax on income and capital gains
distributed to shareholders. In order to preserve its tax status, the Fund must
comply with certain requirements. If the Fund fails to meet these requirements
in any taxable year, it will be subject to tax on its taxable income at
corporate rates, and all distributions from earnings and profits, including any
distributions of net tax-exempt income and net long-term capital gains, will be
taxable to shareholders as ordinary income. In addition, the Fund could be
required to recognize unrealized gains, pay substantial taxes and interest, and
make substantial distributions before regaining its tax status as a regulated
investment company.

INVESTMENT POLICIES
REPURCHASE AGREEMENTS
The Fund may invest in repurchase agreements with commercial banks, brokers or
dealers either for defensive purposes due to market conditions or to generate
income from its excess cash balances. A repurchase agreement is an agreement
under which the Fund acquires a fixed-income security (generally a security
issued by the U.S. Government or an agency thereof, a banker's acceptance or a
certificate of deposit) from a commercial bank, broker or dealer, subject to
resale to the seller at an agreed upon price and date (normally, the next
business day). A repurchase agreement may be considered a loan collateralized by
securities. The resale price reflects an agreed upon interest rate effective for
the period the instrument is held by the Fund and is unrelated to the interest
rate on the underlying instrument. In these transactions, the securities
acquired by the Fund (including accrued interest earned thereon) must have a
total value in excess of the value of the repurchase agreement and are held by
the Fund's custodial bank until repurchased. In addition, the Board of Trustees
will monitor the Fund's repurchase agreement transactions generally and will
establish guidelines and standards for review of the creditworthiness of any
bank, broker or dealer party to a repurchase agreement with the Fund.
The use of repurchase agreements involves certain risks. For example, if
the other party to the agreement defaults on its obligation to repurchase the
underlying security at a time when the value of the security has declined, the
Fund may incur a loss upon disposition of the security. If the other party to
the agreement becomes insolvent and subject to liquidation or reorganization
under bankruptcy or other laws, a court may determine that the underlying
security is collateral for a loan by the Fund not within the control of the Fund
and therefore the Fund may not be able to substantiate its interest in the
underlying security and may be deemed an unsecured creditor of the other party
to the agreement. While the adviser acknowledges these risks, it is expected
that they will be controlled through careful monitoring procedures.
LENDING OF SECURITIES
The Fund may lend its securities on a short-term or long-term basis to qualified
institutional investors (typically brokers, dealers, banks or other financial
institutions) who need to borrow securities in order to complete certain
transactions, such as covering short sales, avoiding failures to deliver
securities, or completing arbitrage operations. By lending its portfolio
securities, the Fund can increase its net investment income through the receipt
of interest on the loan. Any gain or loss in the market price of the securities
loaned that might occur during the term of the loan would be for the account of
the Fund. The terms, the structure and the aggregate amount of such loans must
be consistent with the 1940 Act, and the Rules or interpretations of the
Commission thereunder. These provisions limit the amount of securities a fund
may lend to 33 1/3% of the Fund's total assets, and require that (a) the
borrower pledge and maintain with the Fund collateral consisting of cash, a
letter of credit issued by a domestic U.S. bank, or securities issued or
guaranteed by the United States Government having at all times not less than
100% of the value of the securities loaned, (b) the borrower add to such
collateral whenever the price of the securities loaned rises (i.e., the borrower
"marks to the market" on a daily basis), (c) the loan be made subject to
termination by the Fund at any time and (d) the Fund receive reasonable interest
on the loan (which may include the Fund's investing any cash collateral in
interest-bearing short-term investments), any distribution on the loaned
securities and any increase in their market value. Loan arrangements made by the
Fund will comply with all other applicable regulatory requirements, including
the rules of the New York Stock Exchange, which rules presently require the
borrower, after notice, to redeliver the securities within the normal settlement
time of three business days. All relevant facts and circumstances, including the
creditworthiness of the broker, dealer or institution, will be considered in
making decisions with respect to the lending of securities, subject to review by
the Board of Trustees.
At the present time, the Staff of the Commission does not object if an
investment company pays reasonable negotiated fees in connection with loaned
securities, so long as such fees are set forth in a written contract and
approved by the investment company's trustees. In addition, voting rights pass
with the loaned securities, but if a material event occurs that affects the
securities on loan, the Fund must call the loan and vote the securities.
B-3
<PAGE>
TEMPORARY INVESTMENTS
The Fund may take temporary defensive measures that are inconsistent with the
Fund's normal fundamental or non-fundamental investment policies and strategies
in response to adverse market, economic, political or other conditions. Such
measures could include investments in (a) highly liquid short-term fixed-income
securities issued by or on behalf of municipal or corporate issuers, obligations
of the U.S. Government and its agencies, commercial paper, and bank certificates
of deposit; (b) shares of other investment companies which have investment
objectives consistent with those of the Fund; (c) repurchase agreements
involving any such securities; and (d) other money market instruments. There is
no limit on the extent to which the Fund may take temporary defensive measures.
In taking such measures, the Fund may fail to achieve its investment objective.
VANGUARD INTERFUND LENDING PROGRAM
The Commission has issued an exemptive order permitting the Fund and other
Vanguard funds to participate in Vanguard's interfund lending program. This
program allows the Vanguard funds to borrow money from and loan money to each
other for temporary or emergency purposes. The program is subject to a number of
conditions, including the requirement that no fund may borrow or lend money
through the program unless it receives a more favorable interest rate than is
available from a typical bank for a comparable transaction. In addition, a
Vanguard fund may participate in the program only if and to the extent that such
participation is consistent with the fund's investment objective and other
investment policies. The Boards of Trustees of the Vanguard funds are
responsible for ensuring that the interfund lending program operates in
compliance with all conditions of the Commission's exemptive order.
ILLIQUID SECURITIES
The Fund may invest up to 15% of its net assets in illiquid securities. Illiquid
securities are securities that the Fund may not be able to sell or dispose of in
the ordinary course of business within seven business days at approximately the
value at which they are being carried on the Fund's books.
FUTURES CONTRACTS
The Fund may enter into futures contracts, options, and options on futures
contracts for the purpose of simulating full investment and reducing
transactions costs. The Fund does not use futures or options for speculative
purposes. The Fund will only use futures and options to simulate full investment
in the underlying index while retaining a cash balance for fund management
purposes. Futures contracts provide for the future sale by one party and
purchase by another party of a specified amount of a specific security at a
specified future time and at a specified price. Futures contracts that are
standardized as to maturity date and underlying financial instrument are traded
on national futures exchanges. Futures exchanges and trading are regulated under
the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC), a
U.S. Government Agency. Assets committed to futures contracts will be segregated
to the extent required by law.
Although futures contracts by their terms call for actual delivery or
acceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Closing
out an open futures position is done by taking an opposite position ("buying" a
contract that has previously been "sold," or "selling" a contract previously
purchased) in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is bought or sold.
Futures traders are required to make a good faith margin deposit in cash or
government securities with a broker or custodian to initiate and maintain open
positions in futures contracts. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying security)
if it is not terminated prior to the specified delivery date. Minimal initial
margin requirements are established by the futures exchange and may be changed.
Brokers may establish deposit requirements that are higher than the exchange
minimums. Futures contracts are customarily purchased and sold on deposits which
may range upward from less than 5% of the value of the contract being traded.
After a futures contract position is opened, the value of the contract is
marked to market daily. If the futures contract price changes to the extent that
the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the
B-4
<PAGE>
contract holder. Variation margin payments are made to and from the futures
broker for as long as the contract remains open. The Fund expects to earn
interest income on its margin deposits.
Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities either held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own, or intend to purchase, the securities underlying the futures contracts
which they trade, and use futures contracts with the expectation of realizing
profits from fluctuations in the prices of underlying securities. The Fund
intends to use futures contracts only for bona fide hedging purposes.
Regulations of the CFTC applicable to the Fund require that all of its
futures transactions constitute bona fide hedging transactions except to the
extent that the aggregate initial margins and premiums required to establish any
non-hedging positions do not exceed five percent of the value of the Fund's
portfolio. The Fund will only sell futures contracts to protect the Fund against
declines in the prices of the securities underlying the futures contracts or
purchase contracts to protect against an increase in the price of securities it
intends to purchase. As evidence of this hedging interest, the Fund expects that
the majority of its futures contract purchases will be "completed"; that is,
equivalent amounts of related securities will have been purchased or are being
purchased by the Fund upon sale of open futures contracts.
Although techniques other than the sale and purchase of futures contracts
could be used to control the Fund's exposure to market fluctuations, the use of
futures contracts may be a more effective means of hedging this exposure. While
the Fund will incur commission expenses in both opening and closing out futures
positions, these costs are lower than transaction costs incurred in the purchase
and sale of the underlying securities.
RESTRICTIONS ON THE USE OF FUTURES CONTRACTS. The Fund will not enter into
futures contract transactions to the extent that, immediately thereafter, the
sum of its initial margin deposits on open contracts exceeds 5% of the market
value of its total assets. In addition, the Fund will not enter into futures
contracts to the extent that its outstanding obligations to purchase securities
under these contracts would exceed 20% of the Fund's total assets.
RISK FACTORS IN FUTURES TRANSACTIONS. Positions in futures contracts may be
closed out only on an Exchange that provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, the Fund would continue to be required to make daily cash payments to
maintain its required margin. In such situations, if the Fund has insufficient
cash, it may have to sell portfolio securities to meet daily margin requirements
at a time when it may be disadvantageous to do so. In addition, the Fund may be
required to make delivery of the instruments underlying futures contracts it
holds. The inability to close options and futures positions could also have an
adverse impact on the ability to effectively hedge. The Fund will minimize the
risk that it will be unable to close out a futures contract by only entering
into futures that are traded on national futures exchanges and for which there
appears to be a liquid secondary market.
The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required and the extremely high
degree of leverage involved in futures pricing. As a result, a relatively small
price movement in a futures contract may result in immediate and substantial
loss (as well as gain) to the investor. For example, if at the time of purchase,
10% of the value of the futures contract is deposited as margin, a subsequent
10% decrease in the value of the futures contract would result in a total loss
of the margin deposit, before any deduction for the transaction costs, if the
account were then closed out. A 15% decrease would result in a loss equal to
150% of the original margin deposit if the contract were closed out. Thus, a
purchase or sale of a futures contract may result in losses in excess of the
amount invested in the contract. The Fund also bears the risk that the adviser
will incorrectly predict future stock market trends. However, because the
futures strategy of the Fund is engaged in only for hedging purposes, the Fund's
officers do not believe that the Fund is subject to the risks of loss frequently
associated with futures transactions. The Fund would presumably have sustained
comparable losses if, instead of the futures contract, it had invested in the
underlying financial instrument and sold it after the decline.
Utilization of futures transactions by the Fund does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that the Fund could both lose money on futures contracts and also
experience a decline in value of its portfolio securities. There is also the
risk of
B-5
<PAGE>
loss by the Fund of margin deposits in the event of bankruptcy of a broker with
whom the Fund has an open position in a futures contract or related option.
Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.
FEDERAL TAX TREATMENT OF FUTURES CONTRACTS. The Fund is required for
Federal income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on certain futures contracts as of the end of the
year as well as those actually realized during the year. In these cases, any
gain or loss recognized with respect to a futures contract is considered to be
60% long-term capital gain or loss and 40% short-term capital gain or loss,
without regard to the holding period of the contract. Gains and losses on
certain other futures contracts (primarily non-U.S. futures contracts) are not
recognized until the contracts are closed and are treated as long-term or
short-term depending on the holding period of the contract. Sales of futures
contracts which are intended to hedge against a change in the value of
securities held by the Fund may affect the holding period of such securities
and, consequently, the nature of the gain or loss on such securities upon
disposition. The Fund may be required to defer the recognition of losses on
futures contracts to the extent of any unrecognized gains on related positions
held by the Fund.
In order for the Fund to continue to qualify for federal income tax
treatment as a regulated investment company, at least 90% of its gross income
for a taxable year must be derived from qualifying income; i.e., dividends,
interest, income derived from loans of securities, gains from the sale of
securities or of foreign currencies, or other income derived with respect to the
Fund's business of investing in securities or currencies. It is anticipated that
any net gain on futures contracts will be considered qualifying income for
purposes of the 90% requirement.
The Fund will distribute to shareholders annually any net capital gains
which have been recognized for federal income tax purposes (including unrealized
gains at the end of the Fund's fiscal year) on futures transactions. Such
distributions will be combined with distributions of capital gains realized on
the Fund's other investments and shareholders will be advised on the nature of
the transactions.
FOREIGN INVESTMENTS
The Fund may invest in foreign securities to the extent necessary to carry out
its investment strategy of holding all of the stocks that comprise the index it
tracks. Investors should recognize that investing in foreign companies involves
certain special considerations which are not typically associated with investing
in U.S. companies.
CURRENCY RISK. Since the stocks of foreign companies are frequently
denominated in foreign currencies, and since the Fund may temporarily hold
uninvested reserves in bank deposits in foreign currencies, the Fund will be
affected favorably by changes in currency rates and in exchange control
regulations, and may incur costs in connection with conversions between various
currencies. The investment policies of the Fund permit it to enter into forward
foreign currency exchange contracts in order to hedge the Fund's holdings and
commitments against changes in the level of future currency rates. Such
contracts involve an obligation to purchase or sell a specific currency at a
future date at a price set at the time of the contract.
FEDERAL TAX TREATMENT OF NON-U.S. TRANSACTIONS. Special rules govern the
Federal income tax treatment of certain transactions denominated in terms of a
currency other than the U.S. dollar or determined by reference to the value of
one or more currencies other than the U.S. dollar. The types of transactions
covered by the special rules include the following: (i) the acquisition of, or
becoming the obligor under, a bond or other debt instrument (including, to the
extent provided in Treasury regulations, preferred stock); (ii) the accruing of
certain trade receivables and payables; and (iii) the entering into or
acquisition of any forward contract, futures contract, option or similar
financial instrument if such instrument is not market to market. The disposition
of a currency other than the U.S. dollar by a taxpayer whose functional currency
is the U.S. dollar is also treated as a transaction subject to the special
currency rules. However, foreign currency-related regulated
B-6
<PAGE>
futures contracts and nonequity options are generally not subject to the special
currency rules if they are or would be treated as sold for their fair market
value at year-end under the marking-to-market rules applicable to other futures
contracts unless an election is made to have such currency rules apply. With
respect to transactions covered by the special rules, foreign currency gain or
loss is calculated separately from any gain or loss on the underlying
transaction and is normally taxable as ordinary income or loss. A taxpayer may
elect to treat as capital gain or loss foreign currency gain or loss arising
from certain identified forward contracts, futures contracts and options that
are capital assets in the hands of the taxpayer and which are not part of a
straddle. The Treasury Department issued regulations under which certain
transactions subject to the special currency rules that are part of a "section
988 hedging transaction" (as defined in the Internal Revenue Code of 1986, as
amended, and the Treasury regulations) will be integrated and treated as a
single transaction or otherwise treated consistently for purposes of the Code.
Any gain or loss attributable to the foreign currency component of a transaction
engaged in by the Fund which is not subject to the special currency rules (such
as foreign equity investments other than certain preferred stocks) will be
treated as capital gain or loss and will not be segregated from the gain or loss
on the underlying transaction. It is anticipated that some of the non-U.S.
dollar-denominated investments and foreign currency contracts the Fund may make
or enter into will be subject to the special currency rules described above.
COUNTRY RISK. As foreign companies are not generally subject to uniform
accounting, auditing and financial reporting standards and practices comparable
to those applicable to domestic companies, there may be less publicly available
information about certain foreign companies than about domestic companies.
Securities of some foreign companies are generally less liquid and more volatile
than securities of comparable domestic companies. There is generally less
government supervision and regulation of stock exchanges, brokers and listed
companies than in the U.S. In addition, with respect to certain foreign
countries, there is the possibility of expropriation or confiscatory taxation,
political or social instability, or diplomatic developments which could affect
U.S. investments in those countries.
Although the Fund will endeavor to achieve most favorable execution costs
in its portfolio transactions, fixed commissions on many foreign stock exchanges
are generally higher than negotiated commissions on U.S. exchanges. In addition,
it is expected that the expenses for custodian arrangements of the Fund's
foreign securities will be somewhat greater than the expenses for the custodian
arrangements for handling U.S. securities of equal value.
Certain foreign governments levy withholding taxes against dividend and
interest income. Although in some countries a portion of these taxes is
recoverable, the non-recovered portion of foreign withholding taxes will reduce
the income received from foreign companies held by the Fund. However, these
foreign withholding taxes are not expected to have a significant impact on the
Fund, since the Fund seeks long-term capital appreciation and any income should
be considered incidental.
FUNDAMENTAL INVESTMENT LIMITATIONS
The Fund is subject to the following fundamental investment limitations, which
cannot be changed in any material way without the approval of the holders of a
majority of the Fund's shares. For these purposes, a "majority" of shares means
the lesser of: (i) 67% or more of the votes cast, so long as shares representing
more than 50% of the Fund's net asset value are present or represented by proxy;
or (ii) shares representing more than 50% of the Fund's net asset value.
BORROWING. The Fund may not borrow money, except for temporary or emergency
purposes in an amount not exceeding 15% of the Fund's net assets. The Fund may
borrow money through banks, reverse repurchase agreements, or Vanguard's
interfund lending program only, and must comply with all applicable regulatory
conditions. The Fund may not make any additional investments if its outstanding
borrowings exceed 5% of net assets.
COMMODITIES. The Fund may not invest in commodities, except that it may
invest in stock index futures contracts, stock options and options on stock
index futures contracts. No more than 5% of the Fund's total assets may be used
as initial margin deposit for futures contracts, and no more than 20% of the
Fund's total assets may be invested in futures contracts or options at any time.
B-7
<PAGE>
DIVERSIFICATION. With respect to 75% of its total assets, the Fund may not:
(i) purchase more than 10% of the outstanding voting securities of any one
issuer; or (ii) purchase securities of any issuer if, as a result, more than 5%
of the Fund's total assets would be invested in that issuer's securities. This
limitation does not apply to obligations of the United States Government, its
agencies, or instrumentalities.
ILLIQUID SECURITIES. The Fund may not acquire any security if, as a result,
more than 15% of its net assets would be invested in securities that are
illiquid. From time to time, the Fund's Board of Trustees may determine that
certain restricted securities known as Rule 144A securities are liquid and not
subject to the 15% limitation.
INDUSTRY CONCENTRATION. The Fund may not invest more than 25% of its total
assets in any one industry.
INVESTING FOR CONTROL. The Fund may not invest in a company for purposes of
controlling its management.
INVESTMENT COMPANIES. The Fund may not invest in any other investment
company, except through a merger, consolidation or acquisition of assets, or to
the extent permitted by Section 12 of the 1940 Act. Investment companies whose
shares a Fund acquires pursuant to Section 12 must have investment objectives
and investment policies consistent with those of the Fund.
LOANS. The Fund may not lend money to any person except by purchasing fixed
income securities that are publicly distributed, lending its portfolio
securities, or through Vanguard's interfund lending program.
MARGIN. The Fund may not purchase securities on margin or sell securities
short, except as permitted by the Fund's investment policies relating to
commodities.
OIL, GAS, MINERALS. The Fund may not invest in interests in oil, gas or
other mineral exploration or development programs.
PLEDGING ASSETS. The Fund may not pledge, mortgage or hypothecate more than
15% of its net assets.
PUTS/CALLS. The Fund may not purchase or sell put, call, straddle or spread
options, except as provided above under "Commodities."

may invest in securities of companies that deal in real estate.
SENIOR SECURITIES. The Fund may not issue senior securities, except in
compliance with the 1940 Act.
UNDERWRITING. The Fund may not engage in the business of underwriting
securities issued by other persons. The Fund will not be considered an
underwriter when disposing of its investment securities.
The above-mentioned investment limitations are considered at the time
investment securities are purchased.
PURCHASE OF SHARES
The Fund reserves the right in its sole discretion (i) to suspend the offerings
of its shares, (ii) to reject purchase or exchange orders when in the judgment
of management such rejection is in the best interest of the Fund, (iii) to
impose a transaction fee on a purchase of the Fund's shares if the purchase, in
the opinion of Vanguard, would disrupt the efficient management of the Fund, and
(iv) to reduce or waive the minimum investment for or any other restrictions on
initial and subsequent investments for certain fiduciary accounts or under
circumstances where certain economies can be achieved in sales of the Fund's
shares.
EXCHANGE OF SECURITIES FOR SHARES OF THE FUND. In certain circumstances,
shares of the Fund may be purchased "in-kind," i.e., in exchange for securities,
rather than for cash. The securities tendered as part of an in-kind purchase
must be included in the Index tracked by the Fund and each position must have a
market value of $10,000 or more. Securities accepted by the Fund will be valued
as set forth in the Fund's prospectus as of the time of the next determination
of net asset value after such acceptance. Shares of the Fund are issued at net
asset value determined as of the same time. All dividends, subscription, or
other rights which are reflected in the market price of
B-8
<PAGE>
accepted securities at the time of valuation become the property of the Fund and
must be delivered to the Fund by the investor upon receipt from the issuer. A
gain or loss for Federal income tax purposes would be realized by the investor
upon the exchange depending upon the cost of the securities tendered.
The Fund will not accept securities in exchange for its shares unless: (1)
such securities are, at the time of the exchange, eligible to be held by the
Fund; (2) the transaction will not cause the Fund's weightings to become
imbalanced with respect to the weightings of the stocks included in the Index;
(3) the investor represents and agrees that all securities offered to the Fund
are not subject to any restrictions upon their sale by the Fund under the
Securities Act of 1933, or otherwise; (4) such securities are traded in an
unrelated transaction with a quoted sales price on the same day the exchange
valuation is made; (5) the quoted sales price used as a basis of valuation is
representative (e.g., one that does not involve a trade of substantial size that
artificially influences the price of the security); and (6) the value of any
such security being exchanged will not exceed 5% of the Fund's net assets
immediately prior to the transaction.
Investors interested in purchasing Fund shares in-kind should contact
Vanguard.
SHARE PRICE
The Fund's share price, or "net asset value" per share, is calculated by
dividing the net assets of the Fund attributed to each share class, by the total
number of shares outstanding for each share class. The net asset value is
determined as of the close of the New York Stock Exchange (generally 4:00 p.m.
Eastern time) on each day the Exchange is open for trading.
Portfolio securities for which market quotations are readily available
(includes those securities listed on national securities exchanges, as well as
those quoted on the NASDAQ Stock Market) will be valued at the last quoted sales
price on the day the valuation is made. Such securities which are not traded on
the valuation date are valued at the mean of the bid and ask prices. Price
information on exchange-listed securities is taken from the exchange where the
security is primarily traded. Any foreign securities are valued at the latest
quoted sales price available before the time when assets are valued. Securities
may be valued on the basis of prices provided by a pricing service when such
prices are believed to reflect the fair market value of such securities.
Short-term instruments (those acquired with remaining maturities of 60 days
or less) may be valued at cost, plus or minus any amortized discount or premium,
which approximates market value.
Bonds and other fixed-income securities may be valued on the basis of
prices provided by a pricing service when such prices are believed to reflect
the fair market value of such securities. The prices provided by a pricing
service may be determined without regard to bid or last sale prices of each
security, but take into account institutional-size transactions in similar
groups of securities as well as any developments related to specific securities.
Foreign securities are valued at the last quoted sales price, or the most
recently determined closing price calculated according to local market
convention, available at the time a Fund is valued. Prices are obtained from the
broadest and most representative market on which the securities trade. If events
which materially affect the value of a Fund's investments occur after the close
of the securities markets on which such securities are primarily traded, those
investments may be valued by such methods as the Board of Trustees deems in good
faith to reflect fair value.
In determining a Fund's net asset value per share, all assets and
liabilities initially expressed in foreign currencies will be converted into
U.S. dollars using the officially quoted daily exchange rates used by Morgan
Stanley Capital International in calculating various benchmarking indexes. This
officially quoted exchange rate may be determined prior to or after the close of
a particular securities market. If such quotations are not available or do not
reflect market conditions at the time the Fund is valued, the rate of exchange
will be determined in accordance with policies established in good faith by the
Board of Trustees.
Other assets and securities for which no quotations are readily available
or which are restricted as to sale (or resale) are valued by such methods as the
Board of Trustees deems in good faith to reflect fair value.
The share price for the Fund can be found daily in the mutual fund listings
of most major newspapers under the heading of "Vanguard Index Funds."

REDEMPTION OF SHARES
The Fund may suspend redemption privileges or postpone the date of payment (i)
during any period that the New York Stock Exchange is closed, or trading on the
Exchange is restricted as determined by the Commission, (ii) during any period
when an emergency exists as defined by the Commission as a result of which it is
not reasonably practicable for the Fund to dispose of securities owned by it, or
fairly to determine the value of its assets, and (iii) for such other periods as
the Commission may permit.
The Fund has made an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during any
90-day period to the lesser of $250,000 or 1% of the net assets of the Fund at
the beginning of such period.
No charge is made by the Fund for redemptions. Shares redeemed may be worth
more or less than what was paid for them, depending on the market value of the
securities held by the Fund.

TRUSTEE COMPENSATION
The same individuals serve as Trustees of all Vanguard Trusts (with two
exceptions, which are noted in the table below), and each Trust pays a
proportionate share of Trustees' compensation. The Trusts employ their officers
on a shared basis, as well. However, officers are compensated by The Vanguard
Group, Inc., not the Trusts.
INDEPENDENT TRUSTEES. The Trusts compensate their independent
Trustees--that is, the ones who are not also officers of the Trust--in three
ways:
- - The independent Trustees receive an annual fee for their service to the
Trusts, which is subject to reduction based on absences from scheduled
Board meetings.
- - The independent Trustees are reimbursed for the travel and other expenses
that they incur in attending Board meetings.
- - Upon retirement, the independent Trustees receive an aggregate annual fee
of $1,000 for each year served on the Board, up to fifteen years of
service. This annual fee is paid for ten years following retirement, or
until each Trustee's death.
"INTERESTED" TRUSTEE. Mr. Brennan serves as a Trustee, but is not paid in
this capacity. He is however, paid in his role as officer of The Vanguard Group,
Inc.
COMPENSATION TABLE. The following table provides compensation details for
each of the Trustees. We list the amounts paid as compensation and accrued as
retirement benefits by the Fund for each Trustee. In addition, the table shows
the total amount of benefits that we expect each Trustee to receive from all
Vanguard Trusts upon retirement, and the total amount of compensation paid to
each Trustee by all Vanguard Trusts. All information shown is for the fiscal
year ended December 31, 1999.

THE VANGUARD GROUP
The Fund currently employs The Vanguard Group, Inc. (Vanguard) to provide
management, administrative, and investment advisory services. Vanguard also
provides virtually all of the corporate management, administrative, and
distribution services for The Vanguard Group of Investment Companies, a family
of more than 100 funds. Vanguard also provides investment advisory services on
an at-cost basis to several of the Vanguard funds.
Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Fund and also
furnishes the Fund with the necessary office space, furnishings and equipment.
Vanguard has adopted a Code of Ethics designed to prevent employees who may
have access to nonpublic information about the trading activities of the Fund
(access persons) from profiting from that information. The Code permits access
persons to invest in securities for their own accounts, including securities
that may be held by the Fund, but places substantive and procedural restrictions
on their trading activities. For example, the Code requires that access persons
of the Fund receive advance approval for every securities trade to ensure that
there is no conflict with the trading activities of the Fund.
The Fund receives all investment advisory services from Vanguard. Vanguard
manages the investment and reinvestment of the Fund's assets and continuously
reviews, supervises, and administers the Fund's investment program with respect
to those assets. Vanguard discharges its responsibilities subject to the control
of the officers and Trustees of the Fund.
Vanguard also provides investment advisory services to several other funds.
Total assets under management by Vanguard were approximately $371.4 billion as
of December 31, 1999. The Fund is not actively managed, but is instead
administered by Vanguard using computerized, quantitative techniques.
Under the terms of a Service and Advisory Agreement, Vanguard pays all of
the Fund's expenses, except for taxes and brokerage commissions. For the fiscal
years ended December 31, 1997, 1998, and 1999, the Fund paid approximately
$8,915,000, $12,055,000, and $16,858,000 respectively, to Vanguard for services
rendered under the Service and Advisory Agreement.

PORTFOLIO TRANSACTIONS
In placing portfolio transactions, The Vanguard Group uses its best judgment to
choose the broker most capable of providing the brokerage services necessary to
the obtain best available price and most favorable execution. The full range and
quality of brokerage services available are considered in making these
determinations. In those instances where it is reasonably determined that more
than one broker can offer the brokerage services needed to obtain the best
available price and most favorable execution, consideration is given to those
brokers which supply statistical information and provide other services in
addition to execution services to the Fund.
Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be made through such
firms. However, the Fund may place portfolio orders with qualified
broker-dealers who recommend the Fund to clients, and may, when a number of
brokers and dealers can provide best price and execution on a particular
transaction, consider the sale of Fund shares by a broker or dealer in selecting
among broker dealers.
For the fiscal years ended December 31, 1997, 1998, and 1999, the Fund paid
$820,969, $1,356,000, and $1,455,950 respectively, in brokerage commissions.
FINANCIAL STATEMENTS
The Fund's financial statements as of and for the year ended December 31, 1999,
appearing in the Vanguard Institutional Index Fund 1999 Annual Report to
Shareholders, and the report thereon of PricewaterhouseCoopers LLP, independent
accountants, also appearing therein, are incorporated by reference in this
Statement of Additional Information. For a more complete discussion of the
performance, please see the Fund's Annual Report to Shareholders, which may be
obtained without charge.
YIELD AND TOTAL RETURN
The annualized yield for the Institutional Shares of the Fund for the thirty
days ended December 31, 1999 was 1.10%. The annualized yield for the
Institutional Plus Shares of the Fund for the thirty days ended December 31,
1999 was 1.13%. The average annual total return of the Institutional Shares of
the Fund* for one- and five-year periods ended December 31, 1999, and since
inception on July 31, 1990 was 21.17%, 28.65% and 19.10%, respectively. The
average annual total return of the Institutional Plus Shares of the Fund* for
the one-year period ended December 31, 1999, and since inception on July 7, 1997
was 21.21% and 23.08%, respectively.
- ---------
*The Fund reserves the right to deduct a transaction fee from future purchases
of shares.
AVERAGE ANNUAL TOTAL RETURN
Average annual total return is the average annual compounded rate of return for
the periods of one year, five years, ten years or the life of the Fund, all
ended on the last day of a recent month. Average annual total return quotations
reflect changes in the price of the Fund's shares and assume that all dividends
and capital gains distributions during the respective periods were reinvested in
Fund shares. Average annual total return is calculated by finding the average
annual compounded rates of return of a hypothetical investment over such periods
according to the following formula (average annual total return is then
expressed as a percentage):
T = (ERV/P)(1/N)-1
Where:
T = average annual total return
P = a hypothetical initial investment of $1,000
n = number of years
ERV = ending redeemable value: ERV is the value, at the end of the
applicable period, of a hypothetical $1,000 investment made at
the beginning of the applicable period.
B-13
<PAGE>
AVERAGE ANNUAL AFTER-TAX TOTAL RETURN QUOTATION
We calculate the Fund's average annual after-tax total return by finding the
average annual compounded rate of return over the 1-, 5-, and 10-year periods
(or for periods of the Fund's operations) that would equate the initial amount
invested to the after-tax value, according to the following formulas:
After-tax return:
P(1+T)(N) = ATV
Where:
P = a hypothetical initial payment of $1,000
T = average annual after-tax total return
n = number of years
ATV = after-tax value at the end of the 1-,5-, or 10-year periods of a
hypothetical $1,000 payment made at the beginning of the time
period, assuming no liquidation of the investment at the end of
the measurement periods.
Instructions:
1. Assume all distributions by the Fund are reinvested--less the taxes due on
such distributions--at the price on the reinvestment dates during the
period. Adjustments may be made for subsequent re-characterizations of
distributions.
2 Calculate the taxes due on distributions by the Fund by applying the
highest federal marginal tax rates to each component of the distributions
on the reinvestment date (e.g., ordinary income, short-term capital gain,
long-term capital gain, etc.). For periods after December 31, 1997, the
federal marginal tax rates used for the calculations are 39.6% for ordinary
income and short-term capital gains and 20% for long-term capital gains.
Note that the applicable tax rates may vary over the measurement period.
Assume no taxes are due on the portions of any distributions classified as
exempt interest or non-taxable (i.e. return of capital). Ignore any
potential tax liabilities other than federal tax liabilities (e.g., state
and local taxes).
3. Include all recurring fees that are charged to all shareholder accounts.
For any account fees that vary with the size of the account, assume an
account size equal to the Fund's mean (or median) account size. Assume that
no additional taxes or tax credits result from any redemption of shares
required to pay such fees.
4. State the total return quotation to the nearest hundredth of one percent.
CUMULATIVE TOTAL RETURN
Cumulative total return is the cumulative rate of return on a hypothetical
initial investment of $1,000 for a specified period. Cumulative total return
quotations reflect changes in the price of the Fund's shares and assume that all
dividends and capital gains distributions during the period were reinvested in
Fund shares. Cumulative total return is calculated by finding the cumulative
rates of a return of a hypothetical investment over such periods, according to
the following formula (cumulative total return is then expressed as a
percentage):
C = (ERV/P)-1
Where:
C = cumulative total return
P = a hypothetical initial investment of $1,000
ERV = ending redeemable value: ERV is the value, at the end of the
applicable period, of a hypothetical $1,000 investment made at
the beginning of the applicable period.

SEC YIELDS
Yield is the net annualized yield based on a specified 30-day (or one month)
period assuming semiannual compounding of income. Yield is calculated by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
YIELD = 2[((A-B)/CD+1)(6)-1]
Where:
a = dividends and interest earned during the period.
b = expenses accrued for the period (net of reimbursements).
c = the average daily number of shares outstanding during the
period that were entitled to receive dividends.
d = the maximum offering price per share on the last day of the
period.
