WHY READING THIS PROSPECTUS IS IMPORTANT
This prospectus explains the objective, risks, and policies of Vanguard Prime
Money Market Fund, Vanguard Federal Money Market Fund, and Vanguard Treasury
Money Market Fund. 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 Fund, if any, is the right
investment for you. We suggest that you keep it for future reference.
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
IMPORTANT NOTE
The Prime Money Market Fund features two separate classes of shares: Investor
Shares and Institutional Shares. Prime Money Market Fund Investor Shares has an
investment minimum of $3,000, and is available through this prospectus (for
individual investors) and through a separate prospectus (for participants in
employer-sponsored retirement or savings plans). Prime Money Market Fund
Institutional Shares has an investment minimum of $10 million, and is available
through a separate prospectus. Prime Money Market Fund Investor Shares and Prime
Money Market Fund Institutional Shares do not have the same expenses; as a
result, the performance of these two classes will differ.
- --------------------------------------------------------------------------------
NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

FUND PROFILE -- VANGUARD PRIME MONEY MARKET FUND
The following profile summarizes key features of Vanguard Prime Money Market
Fund.
INVESTMENT OBJECTIVE
The Fund seeks to provide current income while maintaining liquidity and a
stable share price of $1.
INVESTMENT POLICIES
The Fund invests primarily in high-quality, short-term money market instruments,
including certificates of deposit, banker's acceptances, commercial paper, and
other money market securities. To be considered high quality, a security
generally must be rated in one of the two highest credit-quality categories for
short-term securities, by at least two nationally recognized rating services (or
by one, if only one rating service has rated the security). If unrated, the
security must be determined by Vanguard to be of quality equivalent to those in
the two highest credit-quality categories. The Fund will maintain an average
maturity of 90 days or less. For more information about security selection, see
pages 8-10.
PRIMARY RISKS
THE FUND IS SUBJECT TO INCOME RISK, WHICH IS THE CHANCE THAT FALLING SHORT-TERM
INTEREST RATES WILL CAUSE THE FUND'S INCOME -- AND THUS ITS TOTAL RETURN -- TO
DECLINE. INCOME RISK IS GENERALLY HIGH FOR SHORT-TERM SECURITIES. The Fund is
also subject to:
- - Manager risk, which is the chance that poor security selection will cause the
Fund to underperform other funds with similar investment objectives.
- - Credit risk, which is the chance that the issuer of a security will fail to
pay interest and principal in a timely manner. Credit risk, which has the
potential to hurt the Fund's performance, should be low for the Fund.
AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO
PRESERVE THE VALUE OF YOUR INVESTMENT AT $1 PER SHARE, IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN THE FUND.
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 each calendar year over
a ten-year period. The table shows how the Fund's average annual returns for
one, five, and ten calendar years compare with those of a broad-based money
market index. Keep in mind that the Fund's past performance does not indicate
how it will perform in the future.

FUND PROFILE -- VANGUARD FEDERAL MONEY MARKET FUND
The following profile summarizes key features of Vanguard Federal Money Market
Fund.
INVESTMENT OBJECTIVE
The Fund seeks to provide current income while maintaining liquidity and a
stable share price of $1.
INVESTMENT POLICIES
The Fund invests primarily in high-quality, short-term money market instruments
issued by U.S. government agencies. Most of the securities held by the Fund are
not backed by the full faith and credit of the U.S. government. The Fund will
maintain an average maturity of 90 days or less. For more information about
security selection, see pages 8 - 10.
PRIMARY RISKS
THE FUND IS SUBJECT TO INCOME RISK, WHICH IS THE CHANCE THAT FALLING SHORT-TERM
INTEREST RATES WILL CAUSE THE FUND'S INCOME -- AND THUS ITS TOTAL RETURN -- TO
DECLINE. INCOME RISK IS GENERALLY HIGH FOR SHORT-TERM SECURITIES. The Fund is
also subject to:
- - Manager risk, which is the chance that poor security selection will cause the
Fund to underperform other funds with similar investment objectives.
- - Credit risk, which is the chance that the issuer of a security will fail to
pay interest and principal in a timely manner. Credit risk, which has the
potential to hurt the Fund's performance, should be low for the Fund.
An investment in the Fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although the Fund seeks
to preserve the value of your investment at $1 per share, it is possible to lose
money by investing in the Fund.
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 each calendar year over
a ten-year period. The table shows how the Fund's average annual returns for
one, five, and ten calendar years compare with those of a broad-based money
market index. Keep in mind that the Fund's past performance does not indicate

Fund.

The Fund seeks to provide current income while maintaining liquidity and a
stable share price of $1.
INVESTMENT POLICIES
The Fund invests solely in high-quality, short-term money market securities
whose interest and principal payments are backed by the full faith and credit of

PLAIN TALK ABOUT
MONEY MARKET INSTRUMENTS
The term "money market instruments" refers to a variety of short-term
investments, usually with a maturity of 13 months or less. Some common types are
Treasury bills and notes, which are securities issued by the U.S. government;
commercial paper, which is a promissory note issued by a large company or
financial firm; banker's acceptances, which are credit instruments guaranteed by
a bank; and negotiable certificates of deposit, which are issued by banks in
large denominations.
- --------------------------------------------------------------------------------
MORE ON THE FUNDS
The following sections discuss other important features of Vanguard Money Market
Funds, including market exposure, security selection, and costs and
market-timing. You will also find detailed risk information about the Funds
throughout these sections.
MARKET EXPOSURE
Each Fund's primary policy is to invest in very high-quality money market
instruments -- also known as cash reserves -- that are considered short-term
(that is, they mature in 13 months or less). Each Fund will maintain an average
maturity of 90 days or less.
[FLAG GRAPHIC] Each Fund is subject to income risk, which is the possibility
that a Fund's dividends (that is, income) will decline because of
falling interest rates. Because the Funds' income is based on
short-term interest rates -- which can fluctuate significantly
over short periods -- income risk is expected to be high for all
three Funds.
To illustrate how the yields of short-term securities can fluctuate as
interest rates rise and fall, the following chart shows month-end yields for
short-term securities (as represented by 90-day Treasury bills) and long-term
securities (as represented by 30-year U.S. Treasury bonds) over the past five
years.
SHORT-TERM AND LONG-TERM MONTH-END YIELDS (1994-1998)
[LINE CHART]
-----------------------------------------------------------------------
These yields reflect past performance; you should not regard them as an
indication of future returns from either Treasury bills or bonds as a
whole, or any of the Funds in particular.
-----------------------------------------------------------------------
SECURITY SELECTION
Vanguard Fixed Income Group, adviser to the Funds, selects high-quality money
market instruments. Each Fund focuses on securities of a particular class of
issuer (the U.S. government, U.S. government agencies, or non-government
issuers). The Funds are managed without regard to tax ramifications.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
CREDIT QUALITY
A money market instrument's credit quality depends upon the issuer's ability to
pay interest on the security and, ultimately, to repay the debt. The lower the
rating by one of the independent bond-rating agencies (for example, Moody's or
Standard & Poor's), the greater the chance (in the rating agency's opinion) the
security's issuer will default, or fail to meet its payment obligations. Direct
U.S. Treasury obligations (that is, securities backed by the U.S. government)
carry the highest credit ratings. All things being equal, money market
instruments with greater credit risk offer higher yields.
- --------------------------------------------------------------------------------
<PAGE> 12

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
CONVERSION PERIOD FOR MONEY MARKET FUNDS
Before the payment you make to Vanguard can be invested in a money market fund,
it must be converted to "federal funds," which are Federal Reserve deposits that
banks and other financial institutions draw upon to meet short-term cash needs
- -- and which fund advisers must use to pay for the securities they buy. Vanguard
converts your money market investment to federal funds, which usually takes one
business day. Because of this conversion period, your money market account will
be credited on the business day following the day your investment is received.
You will begin earning dividends on your investment on the next calendar day.
For example, if your check is received on a Thursday before the close of trading
on the New York Stock Exchange, your account will be credited the next business
day (Friday) and you will begin earning dividends on Saturday.
- --------------------------------------------------------------------------------
[FLAG GRAPHIC] EACH FUND IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY
THAT THE ADVISER MAY DO A POOR JOB OF SELECTING SECURITIES.
The Prime Money Market Fund invests primarily in certificates of deposit,
banker's acceptances, commercial paper, and other money market securities.
Commercial paper must be rated Prime-1 by Moody's Investors Service or A-1 by
Standard & Poor's Corporation. Securities that are unrated must be issued by a
company with a debt rating of A3 or better by Moody's or A- or better by
Standard & Poor's. The Prime Money Market Fund also invests in short-term
corporate, state, and municipal obligations rated A3 or better by Moody's or A-
or better by Standard & Poor's, and in securities that are considered suitable
for the Federal Money Market Fund (see below).
Among the certificates of deposit typically held by the Prime Money Market
Fund are Eurodollar and Yankee obligations, which are primarily certificates of
deposit issued in U.S. dollars by foreign banks and foreign branches of U.S.
banks. Eurodollar and Yankee obligations have the same risks, such as income
risk and credit risk, as U.S. money market instruments. Other risks of
Eurodollar and Yankee obligations include the possibility that a foreign
government will not let U.S. dollar-denominated assets leave the country; the
possibility that the banks that issue Eurodollar obligations may not be subject
to the same regulations as U.S. banks; and the possibility that adverse
political or economic developments will affect investments in a foreign country.
Before the Fund's adviser selects a Eurodollar or Yankee obligation, however,
any foreign issuer undergoes the same credit-quality analysis and tests of
financial strength as the issuers of domestic securities.
The Federal Money Market Fund invests primarily in securities issued by U.S.
government agencies whose interest and principal payments are not backed by the
full faith and credit of the U.S. government. These agencies include, among
others, the Federal Home Loan Bank, the Federal National Mortgage Association,
and the Federal Home Loan Mortgage Corporation. The Fund also may invest in
securities issued by the U.S. Treasury and U.S. government agencies that are
backed by the full faith and credit of the U.S. government.
The Treasury Money Market Fund invests solely in securities whose interest
and principal payments are backed by the full faith and credit of the U.S.
government. At least 80% of the Fund's assets will always be invested in U.S.
Treasury securities. The remainder of the Fund's assets may include securities
issued by U.S. government agencies, such as the Government National Mortgage
Association, the Small Business Administration, and the Federal Financing Bank.
[FLAG GRAPHIC] EACH FUND IS SUBJECT, TO A LIMITED EXTENT, TO CREDIT RISK, WHICH
IS THE POSSIBILITY THAT THE ISSUER OF A SECURITY WILL FAIL TO PAY
INTEREST AND PRINCIPAL IN A TIMELY MANNER.
The three Funds differ mainly in terms of credit risk. In absolute terms,
each Fund's credit quality is very high.
In relative terms, the Treasury Money Market Fund, which invests in
securities backed by the full faith and credit of the U.S. government, offers
the lowest credit risk -- and generally the lowest yield -- of the three Funds.
Not all of the securities included in the Federal Money Market Fund are
backed by the full faith and credit of the U.S. government, and so the potential
credit risk and yield for the Fund are somewhat higher than for the Treasury
Money Market Fund.
<PAGE> 13

While the credit quality of its securities is very high, the Prime Money
Market Fund faces more risk because it invests in money market securities issued
by private companies. It is possible that one or more of these companies may
experience financial difficulties and, as a result, may fail to pay interest to
the Fund or return the Fund's principal when repayment is due. Therefore, the
Prime Money Market Fund offers the highest credit risk, and generally the
highest yield, of the three Funds.
Bear in mind that, while each Fund invests in high-quality money market
instruments, the three Funds are not insured or guaranteed by the FDIC or any
other agency of the U.S. government.

PLAIN TALK ABOUT
REPURCHASE AGREEMENTS
A means of investing money for a short period, repurchase agreements are
contracts in which a U.S. commercial bank or securities dealer sells government
securities and agrees to repurchase the securities on a specific date (normally
the next business day) and at a specific price.
- --------------------------------------------------------------------------------
[FLAG GRAPHIC] THE PRIME AND FEDERAL MONEY MARKET FUNDS RESERVE THE RIGHT TO
INVEST IN REPURCHASE AGREEMENTS, WHICH ARE SUBJECT TO SPECIFIC
RISKS.
Repurchase agreements carry several risks. For instance, if the seller is
unable to repurchase the securities as promised, the Fund may experience a loss
when trying to sell the securities to another person. Or, if the seller becomes
insolvent, a bankruptcy court may determine that the securities do not belong to
the Fund and order that the securities be sold to pay off the seller's debts.
The Funds' adviser believes that these risks can be controlled through careful
security selection and monitoring.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
DERIVATIVES
A derivative is a financial contract whose value, or interest rate, is based on
(or "derived" from) a traditional security (such as a stock or bond), a money
market benchmark (such as U.S. Treasury bill rates or the Federal Funds
Effective Rate), an asset (such as a commodity like gold), or a market index
(such as the S&P 500 Index).
- --------------------------------------------------------------------------------
[FLAG GRAPHIC] THE FUNDS RESERVE THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN
FLOATING-RATE SECURITIES, WHICH ARE TRADITIONAL TYPES OF
DERIVATIVES.
A floating-rate security's interest rate, as the name implies, is not set;
instead, it fluctuates periodically. Generally, the security's yield is based on
a U.S. dollar-based interest-rate benchmark such as the Federal Funds Rate, the
90-day Treasury bill rate, or the London Interbank Offered Rate (LIBOR). These
securities reset their yields on a periodic basis (for example, daily, weekly,
or quarterly) and are closely correlated to changes in money market interest
rates.
The Funds will not use derivatives for speculative purposes or as leveraged
investments that magnify the risks of an investment.
In addition, each Fund may invest up to 10% of its net assets in illiquid
securities. Illiquid securities are securities that cannot be readily resold or
converted into cash.
COSTS AND MARKET-TIMING
The Vanguard Money Market Funds serve both short- and long-term investor needs;
however, other Vanguard funds are intended for long-term investors only.
Investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all of a fund's shareholders. To minimize
these costs, Vanguard's stock, bond, and balanced funds have adopted policies to
discourage short-term trading -- which includes switching back and forth from
the Vanguard Money Market Funds. Please check other Vanguard funds' prospectuses
for specifics on the trading limitations of those funds. Also, all Vanguard
funds, including the Money Market Funds, reserve the right to stop offering
shares at any time or to reject specific purchase requests.
THE VANGUARD FUNDS DO NOT PERMIT MARKET-TIMING. DO NOT INVEST IN THESE FUNDS
IF YOU ARE A MARKET-TIMER.

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.
- --------------------------------------------------------------------------------
THE FUNDS AND VANGUARD
The Funds are members of The Vanguard Group, a family of more than 35 investment
companies with more than 100 distinct investment portfolios holding assets worth
more than $450 billion. All of the Vanguard funds share in the expenses
associated with business operations, such as personnel, office space, equipment,
and advertising.
Vanguard also provides marketing services to the 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.
INVESTMENT ADVISER
Vanguard Fixed Income Group (the "Group"), P.O. Box 2600, Valley Forge, PA
19482, provides advisory services on an at-cost basis to the Prime, Federal, and
Treasury Money Market Funds. For the fiscal year ended November 30, 1998, the
investment advisory expenses for each Fund represented an effective annual rate
of 0.01% of each Fund's average net assets.
The Group places all orders for purchases and sales of Fund securities, and
seeks to obtain the best available price and most favorable execution with
respect to all transactions.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
The Funds' Adviser

YEAR 2000 CHALLENGE
The common practice in computer programming of using just two digits to identify
a year has resulted in the Year 2000 challenge throughout the information
technology industry. If unchanged, many computer applications and systems could
misinterpret dates occurring after December 31, 1999, leading to errors or
failure. Such failure could adversely affect a fund's operations, including
pricing, securities trading, and the servicing of shareholder accounts.
The Vanguard Group is dedicated to providing uninterrupted, high-quality
performance from our computer systems before, during, and after the year 2000.
In July 1998, we completed the renovation and initial testing of our internal
systems. Vanguard is diligently working with external partners, suppliers, and
vendors, including fund managers and other service providers, to assure that the
systems with which we interact remain operational at all times.
In addition to taking every reasonable step to secure our internal systems
and external relationships, Vanguard is further developing contingency plans
intended to assure that unexpected systems failures will not adversely affect
the Funds' operations. Vanguard intends to monitor these processes through the
rollover of 1999 into 2000 and to quickly implement alternate solutions if
necessary.
However, despite Vanguard's efforts and contingency plans, noncompliant
computer systems could have a material adverse effect on a Fund's business,
operations, or financial condition. Additionally, a Fund's performance could be
hurt if a computer-system failure at a company or governmental unit affects the
price of securities the Fund owns.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
DISTRIBUTIONS
As a shareholder, you are entitled to your share of the fund's income from
interest, 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 interest the fund earns from its money market 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 less than or more than one year.
- --------------------------------------------------------------------------------
DIVIDENDS AND TAXES
As a shareholder, you are entitled to your share of a Fund's net income
(interest less expenses). The Funds' income dividends accrue daily and are
distributed monthly. You can choose to receive your income distributions in
cash, or you can have them automatically reinvested in more shares of the Fund.
In either case, these distributions are taxable to you. It is important to note
that distributions that are declared in December -- if paid to you by the end of
January -- are taxed as if they had been paid in December. Vanguard will send
you a statement each year showing the tax status of all of your distributions.
- - Distributions of dividends may be subject to state and local taxes as well.
However, depending on your state's tax rules, the portion of a Fund's
dividends that come from U.S. Treasury securities and other "direct" U.S.
Treasury obligations may be exempt from state and local income taxes. The
Funds will notify you each year how much, if any, of your distribution may
qualify for this exemption.
- - As a Delaware business trust and a fund made up of direct U.S. government
obligations, the Treasury Money Market Fund should be exempt from any
intangibles taxes to the extent that its securities are direct U.S.
government obligations. The Fund will notify you each year how much, if any,
of the Fund's assets qualify for this exemption.
The tax information in this prospectus is provided as general information and
will not apply to you if you are investing through a tax-deferred account such
as an IRA or a qualified employee benefit plan. (Non-U.S. investors may be
subject to U.S. withholding and estate tax.) You should consult your tax adviser
about the tax consequences of an investment in one or more of the Funds.
IMPORTANT NOTE: By law, each Fund must withhold 31% of your taxable
distributions and any redemption proceeds if you do not provide your correct
taxpayer identification number, or certify that it is correct, or if the IRS
instructs the Funds to do so.
<PAGE> 16

SHARE PRICE
Each Fund's share price, called its net asset value, or NAV, is calculated each
business day after the close of trading on the New York Stock Exchange (the NAV
is not calculated on holidays or other days the Exchange is closed). Each Fund's
NAV is expected to remain at a constant $1. Although the stable share price is
not guaranteed, the Funds are managed and securities are purchased to maintain
that price.
The instruments held by the Funds are valued on the basis of amortized cost,
which does not take into account unrealized capital gains or losses.
Newspapers typically list money market fund yields weekly, separately from
listings for other mutual funds. Different newspapers use different
abbreviations for the Funds, but the most common are VangPr, VangFdl, and
VangTrsy.
- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE
This explanation uses the Prime Money Market Fund as an example. The Fund began
fiscal 1998 with a net asset value (price) of $1 per share. During the year, the
Fund earned $.053 per share from investment income (interest and dividends).
Shareholders received $.053 per share in the form of dividend distributions.
A portion of each year's distributions may come from the prior year's income.
The earnings ($.053 per share) minus the distributions ($.053 per share)
resulted in a share price of $1 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 5.42% for the year.
As of November 30, 1998, the Fund had $33.7 billion in net assets. For the
year, its expense ratio was 0.33% ($3.30 per $1,000 of net assets); and its net
investment income amounted to 5.28% of its average net assets.
- --------------------------------------------------------------------------------
FINANCIAL HIGHLIGHTS
The following financial highlights tables are intended to help you understand
each Fund's financial performance for the past five years, 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 year on an investment in the Fund (assuming reinvestment of
all dividends). This information has been derived from the financial statements
audited by PricewaterhouseCoopers LLP, independent accountants, whose report --
along with each Fund's financial statements -- is included in the Funds' most
recent annual report to shareholders. You may have the annual report sent to you
without charge by contacting Vanguard.

past dividend income (assuming that it has been reinvested) plus realized and
unrealized capital appreciation (or depreciation). Neither yield nor total

A NOTE ON INVESTING WITH VANGUARD THROUGH OTHER FIRMS
You may purchase or sell Fund shares through a financial intermediary such as a
bank, broker, or investment adviser. If you invest with Vanguard through an
intermediary, please read that firm's program materials carefully to learn of
any special rules that may apply. For example, special terms may apply to
additional service features, fees or other policies. Consult your intermediary
to determine when your order will be priced.
- --------------------------------------------------------------------------------
BUYING SHARES
You buy your shares at the Fund's next-determined share price (net asset value)
after Vanguard receives your request, which should be $1 per share. Before your
payment can be used to purchase Fund shares, it must be converted to federal
funds, which usually takes one business day. ("Federal funds" are Federal
Reserve deposits that banks and other financial institutions draw upon to meet
short-term cash needs; fund advisers must use federal funds to pay for the
securities they buy.) Because of this conversion period, your fund account will
be credited on the business day following the day we receive your check. You
will begin earning dividends on your investment on the next calendar day. For
example, if we receive your check before the close of trading on the New York
Stock Exchange (generally 4 p.m. Eastern time) on a Thursday, your account will
be credited the next business day (Friday) and you will begin earning dividends
on Saturday.
Each of the Funds is offered on a no-load basis, meaning that you do not pay
sales commissions or 12b-1 distribution fees.

If you buy fund shares through a federal funds wire, your investment begins
earning dividends the next calendar day. You can begin earning dividends
immediately if you notify Vanguard by 10:45 a.m. Eastern time that you intend to
make a wire purchase that day.
- --------------------------------------------------------------------------------
You can redeem (that is, sell or exchange) shares purchased by check or
Vanguard Fund Express 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.
We must consider the interests of all Fund shareholders and so reserve the right
to refuse any purchase that will 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 21.
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 both cases, your transaction will be based on the Fund's next-determined
share price, subject to any special rules discussed in this prospectus. For
exchanges, the purchase side of the transaction will be based on the receiving
fund's next-determined share price, again subject to any special rules discussed
in this prospectus.
- --------------------------------------------------------------------------------
NOTE: Once a redemption is processed and a confirmation number given, the
transaction CANNOT be canceled.
- --------------------------------------------------------------------------------
HOW TO REQUEST A REDEMPTION
You can request a redemption from your Fund account in any one of three ways:
online, by telephone, or by mail. You can also sell shares by check.
- --------------------------------------------------------------------------------
ONLINE REQUESTS [COMPUTER GRAPHIC]
ACCESS VANGUARD at www.vanguard.com
You can use your personal computer to sell or exchange shares of most Vanguard
funds by accessing our website. To establish this service, you must register

that will enable you to sell or exchange shares online (as well as perform other
transactions).

a redemption check at your address of record.

- --------------------------------------------------------------------------------
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:
[CHECKMARK] The ten-digit account number.
[CHECKMARK] The name and address exactly as registered on the account.
[CHECKMARK] The primary Social Security or employer identification number as
registered on the account.
[CHECKMARK] The Personal Identification Number, if applicable.
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 GRAPHIC]
All Account Types Except Retirement:
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.

CHECK REQUESTS [CHECK GRAPHIC]
You can sell shares by writing a check for $250 or more.
- --------------------------------------------------------------------------------
A NOTE ON LARGE REDEMPTIONS
It is important that you call Vanguard before you redeem a large dollar amount.
We must consider the interests of all fund shareholders and so reserve the right
to delay delivery of your redemption proceeds -- up to seven days -- if the
amount will 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 three ways: check, wire
(money market funds and other daily dividend funds only), or exchange to another
Vanguard fund.
- --------------------------------------------------------------------------------
CHECK REDEMPTIONS
Normally, Vanguard will mail your check within two business days of a
redemption.
- --------------------------------------------------------------------------------
WIRE REDEMPTIONS [WIRE GRAPHIC]
The wire redemption option is not automatic; you must establish it by completing
a special form or the appropriate section of your account application. Wire
redemptions can be initiated by mail or by telephone during Vanguard's business
hours, but not online.
For Money Market Funds:
For telephone requests made by 10:30 a.m. EST, the wire will arrive at your bank
by the close of business that same day. Requests made by 4 p.m. EST will arrive
at your bank by the close of business on the following business day.
For Other Daily Dividend Funds:
For telephone requests made by 4 p.m. EST, the wire will arrive at your bank by
the close of business on the following business day.
- --------------------------------------------------------------------------------
EXCHANGE REDEMPTIONS
As described above, an exchange involves using the proceeds of your redemption
to purchase shares of another Vanguard fund.
- --------------------------------------------------------------------------------
<PAGE> 24
21
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:
[CHECKMARK] The Fund name and account number.
[CHECKMARK] The amount of the transaction (in dollars or shares).
[CHECKMARK] Signatures of all owners exactly as registered on the
account (for mail requests).
[CHECKMARK] Signature guarantees (if required).*
[CHECKMARK] Any supporting legal documentation that may be required.
[CHECKMARK] 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 banks, credit unions,
and licensed brokers.
TRANSACTIONS ARE PROCESSED AT THE NEXT-DETERMINED SHARE PRICE AFTER VANGUARD HAS
RECEIVED ALL REQUIRED INFORMATION.
- --------------------------------------------------------------------------------
RETURN YOUR SHARE CERTIFICATES
Any portion of your account represented by share certificates cannot be redeemed
until you return the certificates to Vanguard. Certificates must be returned
(unsigned), along with a letter requesting the sale or exchange you wish to
process, via certified mail to:
The Vanguard Group
455 Devon Park Drive
Wayne, PA 19087-1815
- --------------------------------------------------------------------------------
ALL TRADES FINAL
Vanguard will not cancel any transaction request (including any purchase or
redemption) that we believe to be authentic once the request has been received
and a confirmation number assigned.
- --------------------------------------------------------------------------------
TRANSFERRING REGISTRATION
You can transfer the registration of your Fund shares to another owner by
completing a transfer form and sending it to Vanguard.

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 your 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 markets, a report
from the advisers, and the Funds' 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 we find that 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, however, you may notify
our Investor Information Department at 1-800-662-7447.
- --------------------------------------------------------------------------------
CONFIRMATION STATEMENT
Sent each time you buy, sell, or exchange shares;
confirms the trade date and the amount of your transaction.
- --------------------------------------------------------------------------------
PORTFOLIO SUMMARY [BOOK GRAPHIC]
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

- --------------------------------------------------------------------------------
TAX STATEMENTS
Generally mailed in January; report previous year's dividend distributions,

provides images of the front and back of each checkwriting draft paid in the
previous month. This consolidated statement is sent instead of the original
canceled drafts, which will not be returned.

WHY READING THIS PROSPECTUS IS IMPORTANT
This prospectus explains the objective, risks, and policies of Vanguard Prime
Money Market Fund, Vanguard Federal Money Market Fund, and Vanguard Treasury
Money Market Fund. 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 Fund, if any, is the right
investment for you. We suggest that you keep it for future reference.
IMPORTANT NOTE
The Prime Money Market Fund features two separate classes of shares: Investor
Shares and Institutional Shares. Prime Money Market Fund Investor Shares has an
investment minimum of $3,000, and is available through this prospectus (for
participants in employer-sponsored retirement or savings plans) and through a
separate prospectus (for individual investors). Prime Money Market Fund
Institutional Shares has an investment minimum of $10 million, and is available
through a separate prospectus. Prime Money Market Fund Investor Shares and Prime
Money Market Fund Institutional Shares do not have the same expenses; as a
result, the performance of these two classes will differ.
NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

FUND PROFILE--VANGUARD PRIME MONEY MARKET FUND
The following profile summarizes key features of Vanguard Prime Money Market
Fund.
INVESTMENT OBJECTIVE
The Fund seeks to provide current income while maintaining liquidity and a
stable share price of $1.
INVESTMENT POLICIES
The Fund invests primarily in high-quality, short-term money market instruments,
including certificates of deposit, banker's acceptances, commercial paper, and
other money market securities. To be considered high quality, a security
generally must be rated in one of the two highest credit-quality categories for
short-term securities, by at least two nationally recognized rating services (or
by one, if only one rating service has rated the security). If unrated, the
security must be determined by Vanguard to be of quality equivalent to those in
the two highest credit-quality categories. The Fund will maintain an average
maturity of 90 days or less. For more information about security selection, see
pages 8-10.
PRIMARY RISKS
THE FUND IS SUBJECT TO INCOME RISK, WHICH IS THE CHANCE THAT FALLING SHORT-TERM
INTEREST RATES WILL CAUSE THE FUND'S INCOME--AND THUS ITS TOTAL RETURN--TO
DECLINE. INCOME RISK IS GENERALLY HIGH FOR SHORT-TERM SECURITIES. The Fund is
also subject to:
- - Manager risk, which is the chance that poor security selection will
cause the Fund to underperform other funds with similar investment
objectives.
- - Credit risk, which is the chance that the issuer of a security will
fail to pay interest and principal in a timely manner. Credit risk,
which has the potential to hurt the Fund's performance, should be low
for the Fund.
AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO
PRESERVE THE VALUE OF YOUR INVESTMENT AT $1 PER SHARE, IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN THE FUND.
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 each calendar year over
a ten-year period. The table shows how the Fund's average annual returns for
one, five, and ten calendar years compare with those of a broad-based money
market index. Keep in mind that the Fund's past performance does not indicate
how it will perform in the future.

FUND PROFILE--VANGUARD FEDERAL MONEY MARKET FUND
The following profile summarizes key features of Vanguard Federal Money Market
Fund.
INVESTMENT OBJECTIVE
The Fund seeks to provide current income while maintaining liquidity and a
stable share price of $1.
INVESTMENT POLICIES
The Fund invests primarily in high-quality, short-term money market instruments
issued by U.S. government agencies. Most of the securities held by the Fund are
not backed by the full faith and credit of the U.S. government. The Fund will
maintain an average maturity of 90 days or less. For more information about
security selection, see pages 8-10.
PRIMARY RISKS
THE FUND IS SUBJECT TO INCOME RISK, WHICH IS THE CHANCE THAT FALLING SHORT-TERM
INTEREST RATES WILL CAUSE THE FUND'S INCOME--AND THUS ITS TOTAL RETURN--TO
DECLINE. INCOME RISK IS GENERALLY HIGH FOR SHORT-TERM SECURITIES. The Fund is
also subject to:
- - Manager risk, which is the chance that poor security selection will
cause the Fund to underperform other funds with similar investment
objectives.
- - Credit risk, which is the chance that the issuer of a security will
fail to pay interest and principal in a timely manner. Credit risk,
which has the potential to hurt the Fund's performance, should be low
for the Fund.

FUND PROFILE--VANGUARD TREASURY MONEY MARKET FUND
The following profile summarizes key features of Vanguard Treasury Money Market
Fund.
INVESTMENT OBJECTIVE
The Fund seeks to provide current income while maintaining liquidity and a
stable share price of $1.
INVESTMENT POLICIES
The Fund invests solely in high-quality, short-term money market securities
whose interest and principal payments are backed by the full faith and credit of
the U.S. government. At least 80% of the Fund's assets will always be invested
in U.S. Treasury securities; the remainder of the Fund's assets may be invested
in securities issued by U.S. government agencies. The Fund will maintain an
average maturity of 90 days or less. For more information about security
selection, see pages 8-10.
PRIMARY RISKS
THE FUND IS SUBJECT TO INCOME RISK, WHICH IS THE CHANCE THAT FALLING SHORT-TERM
INTEREST RATES WILL CAUSE THE FUND'S INCOME--AND THUS ITS TOTAL RETURN--TO
DECLINE. INCOME RISK IS GENERALLY HIGH FOR SHORT-TERM SECURITIES. The Fund is
also subject to:
- - Manager risk, which is the chance that poor security selection will
cause the Fund to underperform other funds with similar investment
objectives.
- - Credit risk, which is the chance that the issuer of a security will
fail to pay interest and principal in a timely manner. Credit risk,
which has the potential to hurt the Fund's performance, should be low
for the Fund.
AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO
PRESERVE THE VALUE OF YOUR INVESTMENT AT $1 PER SHARE, IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN THE FUND.
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 each calendar year over
a ten-year period. The table shows how the Fund's average annual returns for
one, five, and ten calendar years compare with those of a broad-based securities
market index. Keep in mind that the Fund's past performance does not indicate
how it will perform in the future.

PLAIN TALK ABOUT
MONEY MARKET INSTRUMENTS
The term "money market instruments" refers to a variety of short-term
investments, usually with a maturity of 13 months or less. Some common types are
Treasury bills and notes, which are securities issued by the U.S. government;
commercial paper, which is a promissory note issued by a large company or
financial firm; banker's acceptances, which are credit instruments guaranteed by
a bank; and negotiable certificates of deposit, which are issued by banks in
large denominations.
MORE ON THE FUNDS
The following sections discuss other important features of Vanguard Money Market
Funds, including market exposure, security selection, and costs and
market-timing. You will also find detailed risk information about the Funds
throughout these sections.
MARKET EXPOSURE
Each Fund's primary policy is to invest in very high-quality money market
instruments--also known as cash reserves--that are considered short-term (that
is, they mature in 13 months or less). Each Fund will maintain an average
maturity of 90 days or less.
[FLAG] EACH FUND IS SUBJECT TO INCOME RISK, WHICH IS THE POSSIBILITY THAT A
FUND'S DIVIDENDS (THAT IS, INCOME) WILL DECLINE BECAUSE OF FALLING
INTEREST RATES. BECAUSE THE FUNDS' INCOME IS BASED ON SHORT-TERM
INTEREST RATES--WHICH CAN FLUCTUATE SIGNIFICANTLY OVER SHORT
PERIODS--INCOME RISK IS EXPECTED TO BE HIGH FOR ALL THREE FUNDS.
To illustrate how the yields of short-term securities can fluctuate as
interest rates rise and fall, the following chart shows month-end yields for
short-term securities (as represented by 90-day Treasury bills) and long-term
securities (as represented by 30-year U.S. Treasury bonds) over the past five
years.
- --------------------------------------------------------------------------------
SHORT-TERM AND LONG-TERM MONTH-END YIELDS (1994-1998)
- --------------------------------------------------------------------------------
[LINE GRAPH OMITTED]
- --------------------------------------------------------------------------------
These yields reflect past performance; you should not regard them as an
indication of future returns from either Treasury bills or bonds as a whole, or
any of the Funds in particular.
- --------------------------------------------------------------------------------
SECURITY SELECTION
Vanguard Fixed Income Group, adviser to the Funds, selects high-quality money
market instruments. Each Fund focuses on securities of a particular class of
issuer (the U.S. government, U.S. government agencies, or non-government
issuers). The Funds are managed without regard to tax ramifications.
PLAIN TALK ABOUT
CREDIT QUALITY
A money market instrument's credit quality depends upon the issuer's ability to
pay interest on the security and, ultimately, to repay the debt. The lower the
rating by one of the independent bond-rating agencies (for example, Moody's or
Standard & Poor's), the greater the chance (in the rating agency's opinion) the
security's issuer will default, or fail to meet its payment obligations. Direct
U.S. Treasury obligations (that is, securities backed by the U.S. government)
carry the highest credit ratings. All things being equal, money market
instruments with greater credit risk offer higher yields.
<PAGE> 39

PLAIN TALK ABOUT
CONVERSION PERIOD FOR MONEY MARKET FUNDS
Before the payment you make to Vanguard can be invested in a money market
fund, it must be converted to "federal funds," which are Federal Reserve
deposits that banks and other financial institutions draw upon to meet
short-term cash needs--and which fund advisers must use to pay for the
securities they buy. Vanguard converts your money market investment to federal
funds, which usually takes one business day. Because of this conversion period,
your money market account will be credited on the business day following the day
your investment is received. You will begin earning dividends on your investment
on the next calendar day. For example, if your check is received on a Thursday
before the close of trading on the New York Stock Exchange, your account will be
credited the next business day (Friday) and you will begin earning dividends on
Saturday.
[FLAG GRAPHIC] EACH FUND IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY
THAT THE ADVISER MAY DO A POOR JOB OF SELECTING SECURITIES.
The Prime Money Market Fund invests primarily in certificates of deposit,
banker's acceptances, commercial paper, and other money market securities.
Commercial paper must be rated Prime-1 by Moody's Investors Service or A-1 by
Standard & Poor's Corporation. Securities that are unrated must be issued by a
company with a debt rating of A3 or better by Moody's or A- or better by
Standard & Poor's. The Prime Money Market Fund also invests in short-term
corporate, state, and municipal obligations rated A3 or better by Moody's or A-
or better by Standard & Poor's, and in securities that are considered suitable
for the Federal Money Market Fund (see below).
Among the certificates of deposit typically held by the Prime Money Market
Fund are Eurodollar and Yankee obligations, which are primarily certificates of
deposit issued in U.S. dollars by foreign banks and foreign branches of U.S.
banks. Eurodollar and Yankee obligations have the same risks, such as income
risk and credit risk, as U.S. money market instruments. Other risks of
Eurodollar and Yankee obligations include the possibility that a foreign
government will not let U.S. dollar-denominated assets leave the country; the
possibility that the banks that issue Eurodollar obligations may not be subject
to the same regulations as U.S. banks; and the possibility that adverse
political or economic developments will affect investments in a foreign country.
Before the Fund's adviser selects a Eurodollar or Yankee obligation, however,
any foreign issuer undergoes the same credit-quality analysis and tests of
financial strength as the issuers of domestic securities.
The Federal Money Market Fund invests primarily in securities issued by
U.S. government agencies whose interest and principal payments are not backed by
the full faith and credit of the U.S. government. These agencies include, among
others, the Federal Home Loan Bank, the Federal National Mortgage Association,
and the Federal Home Loan Mortgage Corporation. The Fund also may invest in
securities issued by the U.S. Treasury and U.S. government agencies that are
backed by the full faith and credit of the U.S. government.
The Treasury Money Market Fund invests solely in securities whose interest
and principal payments are backed by the full faith and credit of the U.S.
government. At least 80% of the Fund's assets will always be invested in U.S.
Treasury securities. The remainder of the Fund's assets may include securities
issued by U.S. government agencies, such as the Government National Mortgage
Association, the Small Business Administration, and the Federal Financing Bank.
[FLAG GRAPHIC] EACH FUND IS SUBJECT, TO A LIMITED EXTENT, TO CREDIT RISK,
WHICH IS THE POSSIBILITY THAT THE ISSUER OF A SECURITY WILL
FAIL TO PAY INTEREST AND PRINCIPAL IN A TIMELY MANNER.
The three Funds differ mainly in terms of credit risk. In absolute terms,
each Fund's credit quality is very high.
In relative terms, the Treasury Money Market Fund, which invests in
securities backed by the full faith and credit of the U.S. government, offers
the lowest credit risk--and generally the lowest yield--of the three Funds.
Not all of the securities included in the Federal Money Market Fund are
backed by the full faith and credit of the U.S. government, and so the potential
credit risk and yield for the Fund are somewhat higher than for the Treasury
Money Market Fund.
<PAGE> 40
10
While the credit quality of its securities is very high, the Prime Money
Market Fund faces more risk because it invests in money market securities issued
by private companies. It is possible that one or more of these companies may
experience financial difficulties and, as a result, may fail to pay
interest to the Fund or return the Fund's principal when repayment is due.
Therefore, the Prime Money Market Fund offers the highest credit risk, and
generally the highest yield, of the three Funds.
Bear in mind that, while each Fund invests in high-quality money market
instruments, the three Funds are not insured or guaranteed by the FDIC or any
other agency of the U.S. government.
PLAIN TALK ABOUT
REPURCHASE AGREEMENTS
A means of investing money for a short period, repurchase agreements are
contracts in which a U.S. commercial bank or securities dealer sells government
securities and agrees to repurchase the securities on a specific date (normally
the next business day) and at a specific price.
PLAIN TALK ABOUT
DERIVATIVES
A derivative is a financial contract whose value, or interest rate, is based on
(or "derived" from) a traditional security (such as a stock or bond), a money
market benchmark (such as U.S. Treasury bill rates or the Federal Funds
Effective Rate), an asset (such as a commodity like gold), or a market index
(such as the S&P 500 Index).
[FLAG GRAPHIC] THE PRIME AND FEDERAL MONEY MARKET FUNDS RESERVE THE RIGHT TO
INVEST IN REPURCHASE AGREEMENTS, WHICH ARE SUBJECT TO SPECIFIC
RISKS.
Repurchase agreements carry several risks. For instance, if the seller is
unable to repurchase the securities as promised, the Fund may experience a loss
when trying to sell the securities to another person. Or, if the seller becomes
insolvent, a bankruptcy court may determine that the securities do not belong to
the Fund and order that the securities be sold to pay off the seller's debts.
The Funds' adviser believes that these risks can be controlled through careful
security selection and monitoring.
[FLAG GRAPHIC] THE FUNDS RESERVE THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN
FLOATING-RATE SECURITIES, WHICH ARE TRADITIONAL TYPES OF
DERIVATIVES.
A floating-rate security's interest rate, as the name implies, is not set;
instead, it fluctuates periodically. Generally, the security's yield is based on
a U.S. dollar-based interest-rate benchmark such as the Federal Funds Rate, the
90-day Treasury bill rate, or the London Interbank Offered Rate (LIBOR). These
securities reset their yields on a periodic basis (for example, daily, weekly,
or quarterly) and are closely correlated to changes in money market interest
rates.
The Funds will not use derivatives for speculative purposes or as leveraged
investments that magnify the risks of an investment.
In addition, each Fund may invest up to 10% of its net assets in illiquid
securities. Illiquid securities are securities that cannot be readily resold or
converted into cash.
COSTS AND MARKET-TIMING
The Vanguard Money Market Funds serve both short- and long-term investor needs;
however, other Vanguard funds are intended for long-term investors only.
Investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all of a fund's shareholders. To minimize
these costs, Vanguard's stock, bond, and balanced funds have adopted policies to
discourage short-term trading--which includes switching back and forth from the
Vanguard Money Market Funds. Please check other Vanguard funds' prospectuses for
specifics on the trading limitations of those funds. Also, all Vanguard funds,
including the Money Market Funds, reserve the right to stop offering shares at
any time or to reject specific purchase requests.
THE VANGUARD FUNDS DO NOT PERMIT MARKET-TIMING. DO NOT INVEST IN THESE FUNDS
IF YOU ARE A MARKET-TIMER.

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.
THE FUNDS AND VANGUARD
The Funds are members of The Vanguard Group, a family of more than 35
investment companies with more than 100 distinct investment portfolios holding
assets worth more than $450 billion. All of the Vanguard funds share in the
expenses associated with business operations, such as personnel, office space,
equipment, and advertising.
Vanguard also provides marketing services to the 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.
INVESTMENT ADVISER
Vanguard Fixed Income Group (the "Group"), P.O. Box 2600, Valley Forge, PA
19482, provides advisory services on an at-cost basis to the Prime, Federal, and
Treasury Money Market Funds. For the fiscal year ended November 30, 1998, the
investment advisory expenses for each Fund represented an effective annual rate
of 0.01% of each Fund's average net assets.
The Group places all orders for purchases and sales of Fund securities, and
seeks to obtain the best available price and most favorable execution with
respect to all transactions.
PLAIN TALK ABOUT
THE FUNDS' ADVISER

YEAR 2000 CHALLENGE The common practice in computer programming of using just
two digits to identify a year has resulted in the Year 2000 challenge throughout
the information technology industry. If unchanged, many computer applications
and systems could misinterpret dates occurring after December 31, 1999, leading
to errors or failure. Such failure could adversely affect a fund's operations,
including pricing, securities trading, and the servicing of shareholder
accounts.
The Vanguard Group is dedicated to providing uninterrupted, high-quality
performance from our computer systems before, during, and after the year 2000.
In July 1998, we completed the renovation and initial testing of our internal
systems. Vanguard is diligently working with external partners, suppliers, and
vendors, including fund managers and other service providers, to assure that the
systems with which we interact remain operational at all times.
In addition to taking every reasonable step to secure our internal systems
and external relationships, Vanguard is further developing contingency plans
intended to assure that unexpected systems failures will not adversely affect
the Funds' operations. Vanguard intends to monitor these processes through the
rollover of 1999 into 2000 and to quickly implement alternate solutions if
necessary.
However, despite Vanguard's efforts and contingency plans, noncompliant
computer systems could have a material adverse effect on a Fund's business,
operations, or financial condition. Additionally, a Fund's performance could be
hurt if a computer-system failure at a company or governmental unit affects the
price of securities the Fund owns.
DIVIDENDS AND TAXES
As a shareholder, you are entitled to your share of a Fund's net income
(interest less expenses). The Funds' income dividends accrue daily and are
distributed monthly.
Dividend distributions of Fund shares that are held as an investment option
in an employer-sponsored retirement or savings plan will be reinvested in
additional Fund shares and accumulate on a tax-deferred basis. You will not owe
taxes on these distributions until you begin withdrawals. You should consult
your plan administrator, your plan's Summary Description, or your tax adviser
about the tax consequences of an investment in any of the Funds and of any plan
withdrawals.
SHARE PRICE
Each Fund's share price, called its net asset value, or NAV, is calculated
each business day after the close of trading on the New York Stock Exchange (the
NAV is not calculated on holidays or other days the Exchange is closed). Each
Fund's NAV is expected to remain at a constant $1. Although the stable share
price is not guaranteed, the Funds are managed and securities are purchased to
maintain that price.
The instruments held by the Funds are valued on the basis of amortized cost,
which does not take into account unrealized capital gains or losses.
Newspapers typically list money market fund yields weekly, separately from
listings for other mutual funds. Different newspapers use different
abbreviations for the Funds, but the most common are VANGPR, VANGFDL, and
VANGTRSY.
PLAIN TALK ABOUT
DISTRIBUTIONS
As a shareholder, you are entitled to your share of the fund's income from
interest, 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 interest the fund earns from its money market 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 less than or more than one year.

FINANCIAL HIGHLIGHTS
The following financial highlights tables are intended to help you understand
each Fund's financial performance for the past five years, 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 year on an investment in the Fund (assuming reinvestment of
all dividends). This information has been derived from the financial statements
audited by PricewaterhouseCoopers LLP, independent accountants, whose
report--along with each Fund's financial statements--is included in the Funds'
most recent annual report to shareholders. You may have the annual report sent
to you without charge by contacting Vanguard.

From time to time, the Vanguard funds advertise yield and total return
figures. Yield is a measure of past dividend income. Total return includes both
past dividend income (assuming that it has been reinvested) plus realized and
unrealized capital appreciation (or depreciation). Neither yield nor total
return should be used to predict the future performance of a fund.
PLAIN TALK ABOUT
HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE
This explanation uses the Prime Money Market Fund as an example. The Fund began
fiscal 1998 with a net asset value (price) of $1 per share. During the year, the
Fund earned $.053 per share from investment income (interest and dividends).
Shareholders received $.053 per share in the form of dividend distributions.
A portion of each year's distributions may come from the prior year's income.
The earnings ($.053 per share) minus the distributions ($.053 per share)
resulted in a share price of $1 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 5.42% for the year.
As of November 30, 1998, the Fund had $33.7 billion in net assets. For the
year, its expense ratio was 0.33% ($3.30 per $1,000 of net assets); and its net
investment income amounted to 5.28% of its average net assets.

DESCRIPTION OF THE TRUST
ORGANIZATION
The Trust was organized as a Delaware business trust in August, 1996. Prior
to its organization as a Delaware business trust, the Trust operated as the U.S.
Treasury Portfolio of Vanguard Money Market Reserves, a separate investment
company. The Trust is registered with the United States Securities and Exchange
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 class of shares: Vanguard Treasury Money Market Fund (the
"Fund").
The Trust 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 Trust may
issue for a single fund or class of shares.
SERVICE PROVIDERS
CUSTODIAN. First Union National Bank, PA4943, 530 Walnut Street,
Philadelphia, Pennsylvania 19106, serves as the Trust's custodian. The custodian
is responsible for maintaining the Fund's assets and keeping all necessary
accounts and records.
INDEPENDENT ACCOUNTANTS. PricewaterhouseCoopers LLP, 30 South 17th Street,
Philadelphia, Pennsylvania 19103, serves as the Trust's independent accountants.
The accountants audit the Trust's financial statements and provide other related
services.
TRANSFER AND DIVIDEND-PAYING AGENT. The Fund's transfer agent and
dividend-paying agent is The Vanguard Group, Inc., 100 Vanguard Boulevard,
Malvern, Pennsylvania 19355.

<PAGE> 50
CHARACTERISTICS OF THE TRUST'S SHARES
RESTRICTIONS ON HOLDING OR DISPOSING OF SHARES. There are no restrictions
on the right of shareholders to retain or dispose of the Trust's shares, other
than the possible future termination of the Trust or any of its funds. The Trust
or any of its funds may be terminated by reorganization into another mutual fund
or by liquidation and distribution of the assets of the affected fund. Unless
terminated by reorganization or liquidation, the Trust and its funds will
continue indefinitely.
SHAREHOLDER LIABILITY. The Trust 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 of the Trust will
not be personally liable for payment of the Trust'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 Trust obligation only if the Trust 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 a fund are entitled to receive any
dividends or other distributions declared for such fund. No shares have priority
or preference over any other shares of the same fund with respect to
distributions. Distributions will be made from the assets of a fund, and will be
paid ratably to all shareholders of the fund (or class) according to the number
of shares of such fund (or class) held by shareholders on the record date. The
amount of income dividends per share may vary between separate share classes of
the same fund based upon differences in the way that expenses are allocated
between share classes pursuant to a multiple class plan.
VOTING RIGHTS. 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 fund; 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 Trust's net assets, and to change any
fundamental policy of the Trust. Shareholders of the Trust 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 fund affected by a particular matter are entitled to vote
on that matter. Voting rights are non-cumulative 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 net assets of the applicable fund of
the Trust.
PREEMPTIVE RIGHTS. There are no preemptive rights associated with shares
of the Trust.
CONVERSION RIGHTS. There are no conversion rights associated with shares
of the Trust.
REDEMPTION PROVISIONS. The Trust's redemption provisions are described in
its current prospectus and elsewhere in this Statement of Additional
Information.
SINKING FUND PROVISIONS. The Trust has no sinking fund provisions.
CALLS OR ASSESSMENT. The Trust's shares, when issued, are fully paid and
non-assessable.
TAX STATUS OF THE TRUST
The Trust qualifies as a "regulated investment company" under Subchapter M
of the Internal Revenue Code. This special tax status means that a fund will not
be liable for federal tax on income and capital gains distributed to
shareholders. In order to preserve its tax status, a fund must comply with
certain requirements. If it 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, a
B-2
<PAGE> 51
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
The following policies supplement the investment objective and policies set
forth in the Trust's Prospectus:
LENDING OF SECURITIES. The Fund may lend its investment securities 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 investment
securities, the Fund attempts to 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 and the structure and the aggregate amount of
such loans must be consistent with the Investment Company Act of 1940, and the
Rules and Regulations or interpretations of the Securities and Exchange
Commission (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, an irrevocable letter of credit 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 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 Fund's Board of Trustees.
VANGUARD INTERFUND LENDING PROGRAM. The SEC has issued an exemptive order
permitting the Fund 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 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 SEC's exemptive order.
ILLIQUID SECURITIES. The Fund may invest up to 10% of its net assets in
illiquid securities. Illiquid securities are securities that may not be sold or
disposed 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.
The Fund may invest in restricted, privately placed securities that, under
SEC rules, may be sold only to qualified institutional buyers. Because these
securities can be resold only to qualified institutional buyers, they may be
considered illiquid securities -- meaning that they could be difficult for the
Fund to convert to cash if needed.
If a substantial market develops for a restricted security held by the
Fund, it will be treated as a liquid security, in accordance with procedures and
guidelines approved by the Fund's Board of Trustees. This generally includes
securities that are unregistered that can be sold to qualified institutional
buyers in accordance with Rule 144A under the 1933 Act. While the Fund's
investment adviser determines the liquidity of restricted securities on a daily
basis, the Board oversees and retains ultimate responsibility for the adviser's
decisions. Several factors the Board considers in monitoring these decisions
include the valuation of a
B-3
<PAGE> 52
security, the availability of qualified institutional buyers, and the
availability of information about the security's issuer.
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 the
Fund's shares means shares representing the lesser of: (i) 67% or more of the
votes cast to approve a change, so long as shares representing more than 50% of
the Fund's net asset value are present or represented by proxy; or (ii) 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, or Vanguard's interfund lending program
only, and must comply with all applicable regulatory conditions. The Fund may
not borrow to increase income (leveraging), but only to facilitate redemption
requests which might otherwise require untimely dispositions of portfolio
securities. When borrowing exceeds 5% of the Fund's net assets, the Fund will
repay all borrowings before making additional investments, and interest paid on
such borrowings will reduce net income.
COMMODITIES. The Fund may not invest in commodities or commodity
contracts.
DIVERSIFICATION. The Fund may not 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. The Fund may, however,
invest in a single issuer as permitted by the Securities and Exchange Commission
(which currently permits a money market fund to invest up to 25% of its total
assets in the highest-quality securities of a single issuer for a period of up
to three business days).
ILLIQUID SECURITIES. The Fund may not acquire any security if, as a
result, more than 10% of its net assets would be invested in securities that are
illiquid.
INDUSTRY CONCENTRATION. The Fund may not invest more than 25% of its total
assets in any one industry, provided that there is no limitation with respect to
investments in United States Treasury Bills, other obligations issued or
guaranteed by the Federal Government, its agencies and instrumentalities or
certificates of deposit or banker's acceptances of domestic institutions.
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 the Fund acquires pursuant to Section 12 must have investment objectives
and investment policies consistent with those of the Fund.
LOANS. The Fund may not make loans to other persons, except by the
purchase of obligations in which the Fund is authorized to invest, or through
Vanguard's interfund lending program; provided, however, that the Fund may not
enter into repurchase agreements if, as a result thereof, more than 10% of the
net assets of the Fund (taken at current value) would be subject to repurchase
agreements maturing in more than seven days.
MARGIN. The Fund may not purchase securities on margin or sell securities
short.
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 pledge, mortgage or hypothecate its assets
in an amount up to 15% of its net assets, but only to secure borrowings for
temporary or emergency purposes.
B-4
<PAGE> 53
PUT, CALL, STRADDLE, SPREAD OPTIONS. The Fund may not write or invest in
put, call, straddle, or spread options.
REAL ESTATE. The Fund may not invest directly in real estate, or real
estate investment trust securities.
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.
None of these limitations prevents the Fund from participating in The
Vanguard Group ("Vanguard"). Because the Trust is a member of the Group, the
Fund may own securities issued by Vanguard, make loans to Vanguard, and
contribute to Vanguard's costs or other financial requirement. See "Management
of the Trust" for more information.
The above-mentioned investment limitations are considered at the time
investment securities are purchased.
YIELD AND TOTAL RETURN
The yield of the Fund for the 7-day period ended November 30, 1998 is set
forth below. Yields are calculated daily for the Fund.
<TABLE>
<S> <C>

<S> <C> <C> <C> <C>

</TABLE>
Total return is computed by finding the average compounded rates of return
over the periods set forth above that would equate an initial amount invested at
the beginning of the periods to the ending redeemable value of the investment.
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
will 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
<TABLE>
<S> <C> <C>
Where:
T = average annual total return
P = a hypothetical initial investment of $1,000
n = number of years
= ending redeemable value: ERV is the value, at the end of the
ERV applicable period, of a hypothetical $1,000 investment made
at the beginning of the applicable period.
</TABLE>
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
B-5
<PAGE> 54
over such periods, according to the following formula (cumulative total return
is then expressed as a percentage):
C = (ERV/P)-1
<TABLE>
<S> <C> <C>
Where:
C = cumulative total return
P = a hypothetical initial investment of $1,000
= ending redeemable value: ERV is the value, at the end of the
ERV applicable period, of a hypothetical $1,000 investment made
at the beginning of the applicable period.
</TABLE>
CALCULATION OF YIELD
The current yield of the Fund is calculated daily on a base period return
of a hypothetical account having a beginning balance of one share for a
particular period of time (generally 7 days). The return is determined by
dividing the net change (exclusive of any capital changes) in such account by
its average net asset value for the period, and then multiplying it by 365/7 to
get the annualized current yield. The calculation of net change reflects the
value of additional shares purchased with the dividends by the Fund, including
dividends on both the original share and on such additional shares. An effective
yield, which reflects the effects of compounding and represents an annualization
of the current yield with all dividends reinvested, may also be calculated for
the Fund by adding 1 to the net change, raising the sum to the 365/7 power, and
subtracting 1 from the result.
Set forth below is an example, for purposes of illustration only, of the
current and effective yield calculations for the Fund for the 7-day base period
ended November 30, 1998.

*Exclusive of any capital changes and income other than investment income.
The Fund seeks to maintain, but does not guarantee, a constant net asset
value of $1.00. The yield of the Fund will fluctuate. The Trust has obtained
private insurance that partially protects the Treasury Money Market Fund against
default of principal or interest payments on the instruments it holds, and
against bankruptcies by issuers of instruments and credit enhancers on
instruments. Treasury and other U.S. Government securities held by the Fund are
excluded from this coverage. The annualization of a week's dividend is not a
representation by the Fund as to what an investment in the Fund will actually
yield in the future. Actual yields will depend on such variables as investment
quality, average maturity, the type of instruments the Fund invests in, changes
in interest rates on instruments, changes in the expenses of the Trust and other
factors. Yields are one basis investors may use to analyze the Fund, and other
investment vehicles; however, yields of other investment vehicles may not be
comparable because of the factors set forth in the preceding sentence,
differences in the time periods compared, and differences in the methods used in
valuing portfolio instruments, computing net asset values and calculating
yields.
SHARE PRICE
The Fund's share price, or "net asset value" per share, is calculated by
dividing the total assets of the Fund, less all liabilities, by the total number
of shares outstanding. 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 that the
Exchange is open for trading.
B-6
<PAGE> 55
It is the policy of the Fund to attempt to maintain a net asset value of
$1.00 per share for sales and redemptions. The instruments held by the Fund are
valued on the basis of amortized cost, which does not take into account
unrealized capital gains or losses. This involves valuing an instrument at its
cost and thereafter assuming a constant amortization to maturity of any discount
or premium, regardless of the impact of fluctuating interest rates on the market
value of the instrument. While this method provides certainty in valuation, it
may result in periods during which value, as determined by amortized cost, is
higher or lower than the price which the Fund would receive if it sold the
instrument. Such procedures will include a review of the Fund's holdings by the
Trustees, at such intervals as they may deem appropriate, to determine whether
the Fund's net asset value calculated by using available market quotations
deviates from $1.00 per share based on amortized cost. The extent of any
deviation will be examined by the Trustees. If such deviation exceeds 1/2 of 1%,
the Trustees will promptly consider what action, if any, will be initiated. In
the event the Trustees determine that a deviation exists which may result in
material dilution or other unfair results to investors or existing shareholders,
they have agreed to take such corrective action as they regard as necessary and
appropriate, including the sale of fund instruments prior to maturity to realize
capital gains or losses or to shorten average fund maturity; withholding
dividends; making a special capital distribution; redemptions of shares in kind;
or establishing a net asset value per share by using available market
quotations.
The use of amortized cost and the maintenance of the Fund's net asset value
at $1.00 is based on its election to operate under Rule 2a-7 under the 1940 Act.
As a condition of operating under that rule, the Fund must maintain a
dollar-weighted average portfolio maturity of 90 days or less, purchase only
instruments having remaining maturities of 397 days or less, and invest only in
securities that are determined by methods approved by the Trustees to present
minimal credit risks and that are of high quality as determined by the requisite
rating services, or in the case of an instrument not so rated, determined by
methods approved by the Trustees to be of comparable quality.
PURCHASE OF SHARES
The Trust reserves the right in its sole discretion (i) to suspend the
offerings of its shares, (ii) to reject purchase orders when in the judgment of
management such rejection is in the best interest of the Trust, and (iii) 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 Trust's shares.
REDEMPTION OF SHARES

permit.

*Officers of the Trust are "interested persons" as defined in the Investment
Company Act of 1940.
THE VANGUARD GROUP
The Trust is a member of The Vanguard Group of Investment Companies, which
consists of more than 35 investment companies (the "Trusts"). Through their
jointly-owned subsidiary, The Vanguard Group, Inc. ("Vanguard"), the Trust and
the other Trusts in The Vanguard Group obtain at cost virtually all of their
corporate management, administrative and distribution services. Vanguard also
provides investment advisory services on an at-cost basis to certain of the
Vanguard Trusts.
Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Trusts and also
furnishes the Trusts with necessary office space, furnishings and equipment.
Each Trust pays its share of Vanguard's total expenses which are allocated among
the Trusts under methods approved by the Board of Trustees of each Trust. In
addition, each Trust bears its own direct expenses such as legal, auditing and
custodian fees.
The Trust's Officers are also Officers and employees of Vanguard. No
Officer or employee owns, or is permitted to own, any securities of any external
adviser for the Trusts.
Vanguard adheres to a Code of Ethics established pursuant to Rule 17j-1
under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines similar to, and in many
cases more restrictive than, those recommended by a blue ribbon panel of mutual
fund industry executives.
Vanguard was established and operates under an Amended and Restated Funds'
Service Agreement which was approved by the shareholders of each of the Trusts.
The amounts which each of the Trusts has invested are adjusted from time to time
in order to maintain the proportionate relationship between each Trust's
relative net assets and its contribution to Vanguard's capital. At November 30,
1998, Vanguard Treasury Money Market Fund had contributed capital of $728,000 to
Vanguard, representing 0.02% of the Fund's net assets and 1.0% of Vanguard's
capitalization. The Amended and Restated Funds' Service Agreement provides as
follows: (a) each Vanguard Trust may be called upon to invest up to 0.40% of its
current assets in Vanguard and (b) there is no other limitation on the dollar
amount that each Vanguard Trust may contribute to Vanguard's capitalization.
MANAGEMENT. Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting; and (7) review and evaluation of
advisory and other services provided to the Funds by third parties.
DISTRIBUTION. Vanguard Marketing Corporation, a wholly-owned subsidiary of
The Vanguard Group, Inc., provides all distribution and marketing activities for
the Trusts in the Group. The principal distribution expenses are for
advertising, promotional materials and marketing personnel. Distribution
services may also include organizing and offering to the public, from time to
time, one or more new investment companies which will become members of The
Vanguard Group. The Trustees and Officers of Vanguard determine the
B-11
<PAGE> 60
amount to be spent annually on distribution activities, the manner and amount to
be spent on each Trust, and whether to organize new investment companies.
One half of the distribution expenses of a marketing and promotional nature
is allocated among the Trusts based upon relative net assets. The remaining one
half of those expenses is allocated among the Trusts based upon each Trust's
sales for the preceding 24 months relative to the total sales of the Trusts as a
Group, provided, however, that no Trust's aggregate quarterly rate of
contribution for distribution expenses of a marketing and promotional nature
shall exceed 125% of average distribution expense rate for The Vanguard Group,
and that no Trust shall incur annual distribution expenses in excess of 20/100
of 1% of its average month-end net assets.
During the fiscal years ended November 30, 1996, 1997, and 1998, the Fund
incurred the following amounts of The Vanguard Group's management (including
transfer agency), distribution and marketing expenses: $8,198,000, $9,310,000,
and $11,151,000, respectively.
INVESTMENT ADVISORY SERVICES. Vanguard also provides the Trust and several
other Vanguard Trusts with investment advisory services. These services are
provided on an at-cost basis from a money management staff employed directly by
Vanguard. The compensation and other expenses of this staff are paid by the
Trusts utilizing these services. During the fiscal years ended November 30,
1996, 1997, and 1998, the Fund incurred approximately $338,000, $466,000, and
$453,000 respectively, of Vanguard's expenses relating to investment advisory
services.
TRUSTEE COMPENSATION
The individuals in the following table serve as Trustees of all Vanguard
Trusts, and each Trust pays a proportionate share of the 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" TRUSTEES. The Trusts' interested Trustees -- Messrs. Bogle
and Brennan -- receive no compensation for their service in that capacity.
However, they are paid in their role as officers of The Vanguard Group, Inc.
COMPENSATION TABLE. The following table provides compensation details for
each of the Trustees. For the Trust, we list the amounts paid as compensation
and accrued as retirement benefits by the Trust for each Trustee. In addition,
the table shows the total amount of benefits that we expect each Trustee to
receive from
B-12

all Vanguard Trusts upon retirement, and the total amount of compensation paid

DESCRIPTION OF SECURITIES AND RATINGS
DESCRIPTION OF U.S. GOVERNMENT SECURITIES
As used in the Trust's prospectus, the term "U.S. Government Securities"
refers to a variety of securities which are issued or guaranteed by the United
States Treasury, by various agencies of the United States Government, and by
various instrumentalities which have been established or sponsored by the United
States Government. The term also refers to "repurchase agreements"
collateralized by such securities.
U.S. Treasury Securities are backed by the "full faith and credit" of the
United States. Securities issued or guaranteed by Federal agencies and the U.S.
Government sponsored instrumentalities may or may not be backed by the full
faith and credit of the United States. In the case of securities not backed by
the full faith and credit of the United States, the investor must look
principally to the agency or instrumentality issuing or guaranteeing the
obligation for ultimate repayment, and may not be able to assert a claim against
the United States itself in the event the agency or instrumentality does not
meet its commitment.
Some of the U.S. Government agencies that issue or guarantee securities
include the Export-Import Bank of the United States, Farmers Home
Administration, Federal Housing Administration, Maritime Administration, Small
Business Administration, and The Tennessee Valley Authority.
An instrumentality of the U.S. Government is a government agency organized
under Federal charter with government supervision. Instrumentalities issuing or
guaranteeing securities include, among others, Federal Home Loan Banks, the
Federal Land Banks, Central Bank for Cooperatives, Federal Intermediate Credit
Banks, and the Federal National Mortgage Association.
