LETTER FROM THE CHAIRMAN

Dear Shareholder,

Continuing gains in the stock market and the advisor's favorable stock selection
in strongly performing sectors helped the Investor Shares of Vanguard Growth and
Income Fund to return 15.4% in the first half of fiscal 2004. The fund's Admiral
Shares returned 15.5%.

[PICTURES OF JOHN J. BRENNAN]

The  returns of both share  classes  outpaced  the 12.4%  result of the  average
large-capitalization  core fund;  the 14.1%  return of the Standard & Poor's 500
Index, the fund's primary  benchmark;  and the 15.3% return of the Wilshire 5000
Total Market Index, a measure of the overall equity market.

SMALL STOCKS LED THE WAY
The U.S. stock market's nearly  yearlong rally continued  through the six months
ended  March 31.  Gains were  broad-based  and were  especially  powerful  among
small-cap  stocks.  While the Wilshire 5000 Index gained 15.3% during the fiscal
half-year (as mentioned above), the small stocks represented by the Russell 2000
Index returned 21.7%, a pattern of relative  performance  that is fairly typical
of the early stages of an economic  expansion.  Across the market-cap  spectrum,
returns  of  value-oriented   stocks,  which  generally  trade  at  below-market
valuations relative to their book

                                       1


values,  were higher  than those of their  growth-oriented  counterparts  (those
expected to produce above-average earnings growth).

- --------------------------------------------------------------------------------
Admiral(TM) Shares
A lower-cost  class of shares  available to many  longtime  shareholders  and to

- --------------------------------------------------------------------------------

Although  the  economy  emerged  from  recession  more than two years  ago,  the
recovery has been halting and lopsided,  with remarkable strength in housing and
consumer spending, for example, but persistent weakness in corporate investment,
manufacturing,  and the  labor  market.  During  the past six  months,  however,
economic  reports  began to validate  the stock  market's  optimism,  indicating
robust economic growth, a pickup in  manufacturing,  and signs of improvement in
employment.

International  stocks also generated  excellent  six-month returns.  Respectable
gains in markets  throughout  Europe,  Asia, and Latin America were enhanced for
U.S.-based  investors by the dollar's sharp decline relative to most currencies.

BONDS' RETURNS REFLECTED THEIR YIELDS

Interest rates declined toward 12-month lows,  boosting bond prices, but much of
the six-month return in the fixed income market was generated by income.  (As of
March 31, the yield of the 10-year U.S.  Treasury  note stood at 3.84%,  down 10
basis   points--0.10   percentage   point--from   the  start  of  the   period.)
Investment-grade  taxable bonds,  as measured by the Lehman  Brothers  Aggregate
Bond Index,  returned  3.0%. In general,  bonds issued by companies with shakier
balance  sheets  outperformed  better-quality  credits as  investors  sought out
higher-yielding   securities.   Short-  term   interest   rates   remained  near
generational lows.

STRONG STOCK SELECTION LED TO SOLID GAINS

On the heels of a very good  performance by the Growth and Income Fund in fiscal
2003--when both of the fund's share classes advanced more than 22%--the fund got
off to a resounding  start in fiscal 2004, with both share classes again earning
excellent  returns.  The fund  continued to rebound from the losses it sustained
during the 2000-2002 stock market downturn.

As was the case with the S&P 500 Index sectors,  all of the sectors in which the
fund held stocks had impressive  results during the period.  In particular,  the
financial services, consumer discretionary, and producer durables sectors--which
as a group  represented  more than 40% of the fund's total net assets at the end
of the six months--were major contributors to the fund's performance, accounting
for nearly half of its overall  return.  Strong  stock  selection  by the fund's
advisor, Franklin Portfolio Associates, in these and other sectors gave the fund
a competitive edge over the index during the period. In addition,  an overweight
in integrated  oils,  which enjoyed strong returns as a result of rising oil and
gasoline prices, helped boost the fund's performance compared with the index.

Using quantitative management techniques, Franklin Portfolio Associates attempts
to maintain risk characteristics for the fund that resemble those of the S&P 500
Index, while generating superior returns through stock selection.  In its effort
to enhance the fund's performance,  Franklin uses several stock-selection models
that favor reasonably  valued stocks,  which typically have  price/earnings  and
price/book  multiples  somewhat  below the  averages  for these  measures in the
index.  This strategy may not always be  successful,  but it produced  excellent
results during the fiscal half-year.

For information on specific securities held by the fund, see the Report from the
Advisor on page 5.

THE VIRTUE OF BALANCED INVESTING

It's hard to overstate  the  importance  of having a sound plan when  assembling
your investment portfolio.  To meet your long-term needs, maintain a diversified
portfolio of stocks,  bonds, and short-term  reserves  consistent with your risk
tolerance.  Balancing  your  investments  in  this  way may  enable  you to more
effectively  weather the  volatility  of the  financial  markets--lessening  the
impact of a decline in one asset class, while allowing you to participate in the
gains of others.

                                       3


The  Growth  and  Income  Fund can  play an  integral  role in such a  carefully
crafted, diversified portfolio. You can use the fund as your core stock holding,
then  supplement  it with index or  actively  managed  funds that focus on other
segments of the stock and bond markets.

Thank you for your commitment to Vanguard and to the Growth and Income Fund.

Sincerely,


/s/ JOHN J. BRENNAN

REPORT FROM THE ADVISOR
- --------------------------------------------------------------------------------

The Investor Shares of Vanguard Growth and Income Fund returned 15.4% during the
first half of the fund's  2004  fiscal  year,  topping  the  results of both the
average mutual fund peer and our primary benchmark, the S&P 500 Index.

THE INVESTMENT ENVIRONMENT
In recent months, we have become less concerned about the  sustainability of the
U.S.  economic  recovery  and more  focused  on Federal  Reserve  policy and the
possibility of interest rate increases. At current valuation levels, U.S. equity
prices are considered by some to be particularly  vulnerable to a rise in rates.
Given increasing evidence that the economy is strengthening, the question now is
not so much  whether  rates  will  rise as when and how high.  Complicating  the
environment are the U.S. presidential race and the geopolitical risks associated
with  terrorism  and the  situations  in  Afghanistan  and Iraq.  It is somewhat
surprising  to us that these  exogenous  events have not had more of a dampening
effect on the U.S. markets.

On a more upbeat note, the strength of the economic  recovery--including  recent
reports of solid job growth--has  demonstrated the resiliency of U.S. businesses
and their ability to remain  competitive  in the global  economy.  This has very
positive  implications  for  earnings  growth  and  ultimately  for  stock-price
appreciation.

- --------------------------------------------------------------------------------
Investment  Philosophy
The fund reflects a belief that  superior  long-term  investment  results can be
achieved by using quantitative  methods to select stocks that, in the aggregate,
have risk  characteristics  similar to the S&P 500 Index but that are  currently
undervalued by the market.
- --------------------------------------------------------------------------------

Our investment process has served the fund very well in a difficult environment,
and we believe our reliance on a broadly  diversified  blend of factors to guide
stock-picking has been critical to our recent success.  Minimizing  missteps can
be as  important as picking the best  stocks.  We believe  that our  disciplined
process,  applied uniformly across the portfolio,  is a key element in the value
we deliver to our shareholders.

                                       5


OUR SUCCESSES
Stock  selection  during  the  fiscal  half-year  was  particularly  good in the
financial  services  and  consumer   discretionary   sectors.  Among  individual
holdings, solid returns came from Guidant (medical instruments,  with a focus on
cardiac and  vascular  surgery,  pacemakers,  and  defibrillators);  Countrywide
Financial  (mortgage loans);  Electronic Arts (entertainment  software);  Disney
(media and  entertainment,  boosted by a takeover  offer from  Comcast);  Centex
(construction,  boosted by continued  strength in  home-building);  and Monsanto
(chemicals,  benefiting  from commodity  price increases and the global economic
recovery).  In addition, our positions in Dell (personal computers and servers),
Federated  Department Stores (regional stores),  and Becton,  Dickinson (medical
products) had a positive impact on results.

The  Growth  and  Income  Fund has small  but  consistent  "evergreen"  tilts on
earnings   yield  (the  fund  will   consistently   exhibit  a  slightly   lower
price/earnings ratio than the S&P 500 Index) and toward positive price momentum.
These  attributes  are  embedded  in our stock  selection  process and have been
associated  with positive  returns over the long term.  The emphasis on earnings
yield augmented returns during the last six months.  The focus on price momentum
aided returns during the last three months, but was a slight drag on performance
for the first three months of the fiscal year.

Although we  intentionally  minimize  sector tilts  (measured as the  difference
between the portfolio  weighting and the S&P 500 Index weighting in a particular
industry group),  we don't seek to eliminate them. A small  overweighting in the
energy sector and a small  underweighting in health care contributed  positively
to returns during the semiannual period.

OUR SHORTFALLS
Given the  benefit of  hindsight,  it's easy to say that we wish we had not held
certain stocks during the past six months. However, one benefit of a diversified
portfolio is that no single  holding can have an outsized  impact on  investment
results.  In general,  poor performance during the half-year came from stocks in
which  the  fund  was  overweighted  relative  to the S&P 500  Index  and  whose
corporate  issuers  announced  subpar  results.  Among these were Wyeth (drugs),
AutoNation  (auto  retailer),  and Intel  (semiconductors).  In terms of results
relative to the S&P 500 Index,  we also  suffered  from not owning  three stocks
that benefited

                                       6


from  high-profile  takeover  announcements.  They were  Bank  One,  FleetBoston
Financial, and AT&T Wireless, all included in the index.

OUR POSITIONING

We remain  committed to our disciplined  process of stock  selection,  portfolio
construction, and implementation, and we believe that the Growth and Income Fund
is well positioned to achieve its goal of outperforming  the S&P 500 Index while
maintaining  a similar  level of  investment  risk.  The fund  will  stay  fully
invested in the stocks we consider to be most  undervalued,  and portfolio  risk
will be focused to minimize exposure to downside characteristics. We continue to
believe that the Growth and Income Fund is an excellent choice for those seeking
diversified exposure to large-capitalization U.S. equities.

GLOSSARY OF INVESTMENT TERMS
- --------------------------------------------------------------------------------

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation to the ups and downs of a given market  index.  The index is assigned a
beta of 1.00.  Compared with a given index, a fund with a beta of 1.20 typically
would have seen its share  price rise or fall by 12% when the index rose or fell
by 10%. A fund's beta should be reviewed in conjunction  with its R-squared (see
definition  below).  The  lower the  R-squared,  the less  correlation  there is
between the fund and the index, and the less reliable beta is as an indicator of
volatility.
- --------------------------------------------------------------------------------

EARNINGS  GROWTH RATE.  The average  annual rate of growth in earnings  over the
past five years for the stocks now in a fund.
- --------------------------------------------------------------------------------

EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------

FOREIGN HOLDINGS. The percentage of a fund's equity assets represented by stocks
or depositary receipts of companies based outside the United States.
- --------------------------------------------------------------------------------

MEDIAN  MARKET  CAP.  An  indicator  of the  size of  companies  in which a fund
invests;  the  midpoint  of  market   capitalization   (market  price  x  shares
outstanding) of a fund's stocks, weighted by the proportion of the fund's assets
invested  in each  stock.  Stocks  representing  half of the fund's  assets have
market capitalizations above the median, and the rest are below it.
- --------------------------------------------------------------------------------

PRICE/BOOK  RATIO.  The share price of a stock divided by its net worth, or book
value,  per share.  For a fund,  the weighted  average  price/book  ratio of the
stocks it holds.
- --------------------------------------------------------------------------------

PRICE/EARNINGS  RATIO.  The ratio of a stock's  current  price to its  per-share
earnings over the past year. For a fund, the weighted  average P/E of the stocks
it holds. P/E is an indicator of market expectations about corporate  prospects;
the higher the P/E, the greater the expectations for a company's future growth.
- --------------------------------------------------------------------------------

R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns  from the market in general,  as  measured  by a given  index.  If a
fund's total returns were precisely  synchronized  with an index's returns,  its
R-squared  would be 1.00.  If the fund's  returns  bore no  relationship  to the
index's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------

RETURN ON  EQUITY.  The annual  average  rate of return  generated  by a company
during the past five years for each dollar of  shareholder's  equity (net income
divided by  shareholder's  equity).  For a fund, the weighted  average return on
equity for the companies whose stocks it holds.
- --------------------------------------------------------------------------------

SHORT-TERM  RESERVES.  The  percentage  of a fund  invested  in  highly  liquid,
short-term securities that can be readily converted to cash.
- --------------------------------------------------------------------------------

TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover  rates  incur  higher  transaction  costs  and  may be more  likely  to
distribute capital gains (which may be taxable to investors).
- --------------------------------------------------------------------------------

YIELD.  A snapshot of a fund's  income from interest and  dividends.  The yield,
expressed  as a  percentage  of the fund's net asset  value,  is based on income
earned over the past 30 days and is  annualized,  or  projected  forward for the
coming year. The index yield is based on the current  annualized  rate of income
provided by securities in the index.

ABOUT YOUR FUND'S EXPENSES
- --------------------------------------------------------------------------------

We believe it is  important  for you to  understand  the impact of costs on your
investment.  All mutual funds have operating  expenses.  As a shareholder of the
fund,  you incur ongoing  costs,  which include costs for portfolio  management,
administrative  services, and shareholder reports (like this one), among others.
Operating  expenses,  which are deducted  from a fund's gross  income,  directly
reduce the investment  return of the fund. A fund's  expenses are expressed as a
percentage of its average net assets. This figure is known as the expense ratio.
The following examples are intended to help you understand the ongoing costs (in
dollars)  of  investing  in your fund and to compare  these  costs with those of
other mutual  funds.  The examples are based on an  investment of $1,000 made at
the beginning of the period shown and held for the entire period.

The table below illustrates your fund's costs in two ways:

* ACTUAL FUND  RETURN.  This section  helps you to estimate the actual  expenses
that you paid over the period.  The "Ending Account Value" shown is derived from
the fund's  actual  return,  and the third column  shows the dollar  amount that
would have been paid by an investor who started with $1,000 in the fund. You may
use the information here, together with the amount you invested, to estimate the
expenses that you paid over the period.

To do so, simply  divide your account  value by $1,000 (for  example,  an $8,600
account value  divided by $1,000 = 8.6),  then multiply the result by the number
given for your fund under the heading "Expenses Paid During Period."

*  HYPOTHETICAL  5% RETURN.  This  section is intended to help you compare  your
fund's  costs with those of other mutual  funds.  It assumes that the fund had a
return of 5% before expenses during the period shown, but that the expense ratio
is  unchanged.  In this  case--because  the return used is not the fund's actual
return--the  results do not apply to your  investment.  The example is useful in
making comparisons  because the Securities and Exchange  Commission requires all
mutual funds to  calculate  expenses  based on a 5% return.  You can assess your
fund's  costs by  comparing  this  hypothetical  example  with the  hypothetical
examples that appear in shareholder reports of other funds.

- --------------------------------------------------------------------------------
*Expenses are equal to the fund's  annualized  expense  ratio  multiplied by the
average  account value over the period,  multiplied by the number of days in the
most recent fiscal half-year, then divided by 366.


Please note that the expenses shown in the table are meant to highlight and help
you compare  ongoing  costs only and do not reflect any  transactional  costs or
account maintenance fees. They do not include your fund's low-balance fee, which
is described in the prospectus.  If this fee were applied to your account,  your
costs  would be higher.  Your fund does not  charge  transaction  fees,  such as
purchase or redemption fees, nor does it carry a "sales load."

ABOUT YOUR FUND'S EXPENSES (CONTINUED)

The  calculations  assume no shares were bought or sold during the period.  Your
actual  costs may have been  higher or lower,  depending  on the  amount of your
investment and the timing of any purchases or redemptions.

FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped  and  subtotaled  by asset  type  (common  stocks,  bonds,  etc.) and by
industry sector. Other assets are added to, and liabilities are subtracted from,
the value of Total Investments to calculate the fund's Net Assets.  Finally, Net
Assets are divided by the outstanding  shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets,  you will find a table displaying the
composition of the fund's net assets.  Because all income and any realized gains
must be distributed to  shareholders  each year, the bulk of net assets consists
of Paid-in  Capital  (money  invested by  shareholders).  The amounts  shown for
Undistributed  Net Investment  Income and Accumulated Net Realized Gains usually
approximate  the sums the fund had available to distribute  to  shareholders  as
income  dividends  or capital  gains as of the  statement  date,  but may differ
because  certain  investments or  transactions  may be treated  differently  for
financial  statement and tax purposes.  Any Accumulated Net Realized Losses, and
any cumulative  excess of  distributions  over net income or net realized gains,
will appear as negative balances.  Unrealized Appreciation (Depreciation) is the
difference  between the market value of the fund's  investments  and their cost,
and reflects the gains  (losses) that would be realized if the fund were to sell
all of its investments at their statement-date values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the net amount shareholders invested in
or redeemed  from the fund.  Distributions  and Capital Share  Transactions  are
shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

                                       19


NOTES TO FINANCIAL STATEMENTS

Vanguard Growth and Income Fund is registered  under the Investment  Company Act
of 1940 as an open-end  investment  company, or mutual fund. The fund offers two
classes of shares,  Investor  Shares and  Admiral  Shares.  Investor  Shares are
available to any investor who meets the fund's  minimum  purchase  requirements.
Admiral  Shares are designed  for  investors  who meet  certain  administrative,
servicing, tenure, and account-size criteria.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The fund consistently follows such
policies in preparing its financial statements.

1.   SECURITY VALUATION: Securities are valued as of the close of trading on the
     New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation
     date.  Equity  securities  are valued at the latest  quoted sales prices or
     official  closing  prices  taken  from the  primary  market  in which  each
     security  trades;  such  securities  not traded on the  valuation  date are
     valued at the mean of the latest  quoted bid and asked  prices.  Securities
     for which market quotations are not readily available, or whose values have
     been materially affected by events occurring before the fund's pricing time
     but after the  close of the  securities'  primary  markets,  are  valued by
     methods deemed by the board of trustees to represent fair value.  Temporary
     cash  investments  acquired  over 60 days to maturity  are valued using the
     latest  bid  prices or using  valuations  based on a matrix  system  (which
     considers  such  factors  as  security  prices,  yields,   maturities,  and
     ratings),  both  as  furnished  by  independent  pricing  services.   Other
     temporary cash investments are valued at amortized cost, which approximates
     market value.

2.   FUTURES  CONTRACTS:  The fund uses S&P 500  Index  futures  contracts  to a
     limited  extent,  with the  objective of  maintaining  full exposure to the
     stock market  while  maintaining  liquidity.  The fund may purchase or sell
     futures  contracts  to achieve a desired  level of  investment,  whether to
     accommodate   portfolio   turnover  or  cash  flows  from   capital   share
     transactions.  The  primary  risks  associated  with  the  use  of  futures
     contracts are  imperfect  correlation  between  changes in market values of
     stocks  held by the fund  and the  prices  of  futures  contracts,  and the
     possibility of an illiquid market.

     Futures contracts are valued at their quoted daily settlement  prices.  The
     aggregate  principal  amounts  of the  contracts  are not  recorded  in the
     financial  statements.  Fluctuations  in the  value  of the  contracts  are
     recorded in the Statement of Net Assets as an asset  (liability) and in the
     Statement of Operations as unrealized appreciation (depreciation) until the
     contracts  are closed,  when they are  recorded as realized  futures  gains
     (losses).

3.   REPURCHASE  AGREEMENTS:  The fund, along with other members of The Vanguard
     Group,  transfers uninvested cash balances to a pooled cash account,  which
     is invested in repurchase agreements secured by U.S. government securities.
     Securities  pledged as collateral for  repurchase  agreements are held by a
     custodian bank until the agreements  mature.  Each agreement  requires that
     the market  value of the  collateral  be  sufficient  to cover  payments of
     interest and principal;  however,  in the event of default or bankruptcy by
     the  other  party to the  agreement,  retention  of the  collateral  may be
     subject to legal proceedings.

4.   FEDERAL  INCOME  TAXES:  The fund  intends  to  continue  to  qualify  as a
     regulated  investment  company and  distribute  all of its taxable  income.
     Accordingly,  no  provision  for  federal  income  taxes is required in the
     financial statements.

5.   DISTRIBUTIONS:   Distributions   to   shareholders   are  recorded  on  the
     ex-dividend date.

6.   OTHER:  Dividend  income is  recorded  on the  ex-dividend  date.  Security
     transactions  are accounted for on the date  securities are bought or sold.
     Costs used to determine  realized  gains (losses) on the sale of investment
     securities are those of the specific securities sold.

                                       20


     Each class of shares has equal  rights as to assets  and  earnings,  except
     that each class separately bears certain class-specific expenses related to
     maintenance   of   shareholder   accounts   (included  in  Management   and
     Administrative   expenses)  and   shareholder   reporting.   Marketing  and
     distribution  expenses  are  allocated  to each class of shares  based on a
     method approved by the board of trustees.  Income, other non-class-specific
     expenses,  and gains and losses on investments  are allocated to each class
     of shares based on its relative net assets.

B. Franklin Portfolio  Associates LLC provides  investment  advisory services to
the fund for a fee  calculated  at an  annual  percentage  rate of  average  net
assets.  The basic fee is subject to quarterly  adjustments based on performance
for the preceding three years relative to the S&P 500 Index.  For the six months
ended March 31,  2004,  the  investment  advisory fee  represented  an effective
annual basic rate of 0.09% of the fund's average net assets,  before an increase
of $434,000 (0.01%) based on performance.

C. The Vanguard Group  furnishes at cost corporate  management,  administrative,
marketing,  and distribution  services. The costs of such services are allocated
to the fund  under  methods  approved  by the  board of  trustees.  The fund has
committed to provide up to 0.40% of its net assets in capital  contributions  to
Vanguard.  At March 31, 2004,  the fund had  contributed  capital of $974,000 to
Vanguard (included in Other Assets), representing 0.01% of the fund's net assets
and 0.97% of  Vanguard's  capitalization.  The fund's  trustees and officers are
also directors and officers of Vanguard.

D. The fund has asked its investment  advisor to direct certain security trades,
subject to obtaining the best price and execution, to brokers who have agreed to
rebate to the fund part of the  commissions  generated.  Such  rebates  are used
solely to reduce the fund's management and administrative  expenses. For the six
months ended March 31, 2004, these  arrangements  reduced the fund's expenses by
$434,000 (an annual rate of 0.01% of average net assets).

E.  Distributions  are  determined  on a tax  basis  and  may  differ  from  net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes;  these  differences will reverse at some time in the
future.  Differences  in  classification  may also result from the  treatment of
short-term gains as ordinary income for tax purposes.

The fund's tax-basis  capital gains and losses are determined only at the end of
each  fiscal  year.  For tax  purposes,  at  September  30,  2003,  the fund had
available  realized losses of  $1,811,408,000 to offset future net capital gains
of $19,126,000  through September 30, 2009,  $776,477,000  through September 30,
2010,   $741,889,000  through  September  30,  2011,  and  $273,916,000  through
September 30, 2012. The fund will use these capital losses to offset net taxable
capital  gains,  if any,  realized  during the year ending  September  30, 2004;
should the fund  realize  net  capital  losses for the year,  the losses will be
added to the loss carryforward balances above.

At March 31, 2004, net unrealized  appreciation of investment securities for tax
purposes was $1,274,808,000, consisting of unrealized gains of $1,323,640,000 on
securities  that had risen in value  since their  purchase  and  $48,832,000  in
unrealized losses on securities that had fallen in value since their purchase.

THE PEOPLE WHO GOVERN YOUR FUND

- --------------------------------------------------------------------------------
The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.

A majority of Vanguard's board members are  independent,  meaning that they have
no affiliation  with Vanguard or the funds they oversee,  apart from the sizable
personal investments they have made as private individuals.

Our  independent  board members  bring  distinguished  backgrounds  in business,
academia,  and public service to their task of working with Vanguard officers to
establish the policies and oversee the activities of
