OUR CREW MAKES THE DIFFERENCE

Throughout our history, The Vanguard Group has received considerable attention
as the low-cost provider of mutual funds. While such accolades are gratifying,
we are most proud, not of our low operating expenses or the billions of dollars
we manage, but of our sterling reputation created by the Vanguard crew.

     We recognize that it is our crew members--more than 6,000 highly motivated
men and women--who form the cornerstone of our operations.  As with any
cornerstone, we could not survive long--let alone prosper--without it. That's
why we chose this fiscal year's annual report to celebrate the spirit,
enthusiasm, and achievements of our crew. (We call those who work at Vanguard
crew members, not employees, because they operate as a team to accomplish our
mission of serving you, our clients.)

     But while we prize the collective contributions of our crew, we also take
time to recognize the importance of the individual.  Each calendar quarter, we
present our Award For Excellence to a handful of crew members who have
demonstrated particular excellence in the performance of their jobs and who
embody "The Vanguard Spirit."  Our report cover shows only a few  of the more 
than 300 crew members  who have received this distinction since 1984.

     They, along with the rest of our valiant crew, look forward to serving you
in the years ahead.

FELLOW SHAREHOLDER,

Vanguard Growth and Income Portfolio provided a stellar return of +35.6%
in 1997 as the U.S. stock market turned in another astonishing performance,
capping a three-year run during which market averages more than doubled.

     The Portfolio (formerly designated Vanguard Quantitative Portfolios) not
only smartly outpaced the average value mutual fund but also topped the
unmanaged Standard & Poor's 500 Composite Stock Price Index. The adjacent table
presents the twelve-month total return (capital change plus reinvested
dividends) of the Portfolio and its two comparative standards. Our return is
based on an increase in net asset value from $22.23 per share on December 31,
1996, to $26.19 per share on December 31, 1997, with the latter figure adjusted
for dividends of $0.42 per share paid from net investment income and
distributions totaling $3.18 per share paid from net realized capital gains.

THE FINANCIAL MARKETS IN BRIEF

The historic bull market in U.S. stocks that began in August 1982 continued in
impressive fashion during 1997. The economy, employment, and corporate earnings
all grew solidly, and consumer confidence strengthened. Yet interest rates
declined and inflation decelerated. In short, the domestic economic news
couldn't have been better. The sole dark cloud--severe turmoil in Asian
economies and currencies--only briefly darkened Wall Street's mood. After a
sharp decline in October--the S&P 500 Index tumbled -7% on October 27
alone--stocks resumed their climb, and the Index produced a +33.4% return for
the year.

     Long-term interest rates rose through the first quarter of 1997 on
expectations that the economy's robust growth would cause inflation to
accelerate. The yield on the benchmark 30-year U.S. Treasury bond peaked at
7.17% in mid-April, but drifted lower throughout the year as inflation news got
better, not worse. The 30-year Treasury's yield ended the year at 5.92%, 72
basis points below its level of 6.64% at the end of 1996.

     Short-term interest rates bottomed out in June and began an irregular
climb that was apparently due to sales of short-term Treasuries by foreign
central banks and investors. At year-end 1997, the yield on three-month U.S.
Treasury bills was 5.35%, up from 5.17% when the year began. The spread between
yields on three-month T-bills and 30-year Treasury bonds was a very slim 0.57
percentage point on December 31, 1997. Such a "flattening" of the yield curve
has more often than not been the precursor of a slowdown in the economy.

1997 PERFORMANCE OVERVIEW

Your Portfolio's +35.6% return during 1997 was the second highest in its
eleven-year history, trailing only the +35.9% gain in 1995.  More important,
because our adviser's mandate is to exceed the returns on the S&P 500 Index
while paralleling its risk





                                       1
<PAGE>   4
characteristics, the Portfolio surpassed that goal by +2.2 percentage points.
We achieved a far more substantial margin of +7.9 percentage points over our
average competitor--more than a 28% enhancement.

     The adviser's excellent stock selection, using its computer-driven
quantitative techniques, enhanced returns in several sectors. Our selection of
financial-services stocks, the market's best sector for the year with a +46.9%
return, provided the Portfolio with a +54.7% return. The Portfolio also
benefited from its heavier concentration in this sector (19.0% of assets on
average during the year, versus 16.5% for the S&P 500 Index). In technology
stocks, the Portfolio gained +38.3%, compared with the +28.4% return from the
sector for the Index. Lagging returns among our health care (+29.2%) and
consumer staples (+25.9%) selections proved our major negatives, partially
offset by solid selections in consumer services and even in the oil sector, a
market laggard.

     The Portfolio got a boost versus its competitors from the stock market's
bias toward large-capitalization stocks. The S&P 500 Index, which is dominated
by large-cap stocks, outdistanced by more than 6 percentage points the +27.2%
return on the Russell 2800 Index, a good barometer of mid-cap stocks. This
worked to our advantage in 1997, when the Portfolio held but 20% of its assets
in mid- and small-cap stocks, while the average large value fund held a 30%
position--half again as much in these less-robust equities.

LONG-TERM PERFORMANCE OVERVIEW

The table below compares the Portfolio's record over the decade ended December
31, 1997, with those of the average value fund and the S&P 500 Index. It also
shows how much a hypothetical $10,000 investment made in each on December 31,
1987, would have grown, assuming the reinvestment of all income dividends and
capital gains distributions. As the table shows, we have earned an average of
+2.8% more per year than the average value fund. That advantage adds up
dramatically over a decade. An investment of $10,000 in the Portfolio on
December 31, 1987, would have grown to $53,807 over ten years, compared with
$42,405 for our average competitor. The additional $11,402 wealth created over
the decade is 114% of the entire initial stake.

</TABLE>

     It is a pleasure to report that we also have outperformed the S&P 500 Index
over the decade, though by a small margin. The Index, as you know, is a tough
competitor for all actively managed mutual funds because it exists only on
paper and has none of the operating and transaction costs that all mutual funds
bear to one degree or another. To be sure, index mutual funds are indeed
available, but even the lowest-cost ones tend to lag the Index by about the
0.20% expense ratios (operating costs as a percentage of average net assets)
that they incur. Thus we would have eked out a margin of about 0.40% per year
over such a fund.

     In respect to cost, the Portfolio has a significant advantage over 
competing mutual funds; our annual expense ratio of 0.36% is nearly a full
percentage point below the 1.23% expense ratio of the average value fund. We
fully expect this advantage of nearly





                                       2
<PAGE>   5
1% to persist, regardless of the direction of the financial markets. As mutual
fund investors are slowly learning, costs matter.

     We stress that the long-term returns shown in the table were unusually 
high. They encompass a ten-year period without a single severe downturn in the
U.S. stock market. But there will surely be individual down years ahead, and we
caution that returns from the Growth and Income Portfolio, and from the U.S.
stock market in general, will almost certainly be less generous over the next
decade than during the one just past.

IN SUMMARY

Returns from the U.S. stock market over the past three calendar years--indeed
over the past 15 years--have no precedent in American financial history. While
investors have every reason to be grateful for the bounty of the financial
markets, they also have reason to regard the future with some caution. Lengthy
bull markets can breed complacency and cause investors to discount the risks
inherent in investing in stocks. Make no mistake--the market will from time to
time demonstrate these risks.

     However, the greatest risk is failure to invest in the first place. We
believe that the stock market's risks can be partially offset by holding a
balanced portfolio that also includes bond funds and money market funds.
Investors who maintain such portfolios--allocated in accordance with their time
horizon, financial situation, and tolerance for market volatility--are prepared
to "stay the course" toward their investment objectives, no matter what the
future has in store.

THE MARKETS IN PERSPECTIVE

Year Ended December 31, 1997

U.S. EQUITY MARKETS

Despite some year-end rockiness, 1997 again provided U.S. equity investors with
exceptional returns, as illustrated by the 33.4% advance of the S&P 500 Index.
Investors' mettle was tested several times, however, and most severely by the
upheavals that devastated a number of Asian markets in the fourth quarter.
Beginning in late October, the U.S. market grew increasingly volatile, a direct
result of investors' struggle to understand the nature and implications of
Asia's economic turmoil. By the end of the year, it appeared that a new
consensus was emerging, grounded in two basic beliefs: (1) that the collapse of
currencies in the Far East would help keep inflation tame in the United States
and (2) that slower growth in Asia would most likely lead to weaker corporate
profits over the next several years.

     As the dust continued to settle, many investors sought havens traditional
in periods of high uncertainty: large-capitalization issues and particularly
the "defensive" sectors of the stock market, such as utilities, consumer
staples, and health care. The closing weeks of 1997 saw a broad advance in
these "safe" sectors, with utilities gaining 20.1% and consumer staples 10.4%
in the last quarter. By contrast, more economically sensitive sectors were
thrashed in the wake of the Asian crisis, with technology issues falling 12.3%
and producer durables down 9.0% over the three months. After posting strong
results in the third quarter, small-company stocks also suffered in the fourth,
falling 3.3%.

</TABLE>

     The year-end excitement did not detract from 1997's overall record as a
stellar year for U.S. stock investors. The best-performing sector was financial
services, which rose 46.9%. This sector benefited from a number of factors,
including the strength of the economy, the vibrant financial markets, and
merger activity. By contrast, the commodity-oriented materials & processing
sector posted a gain of "only" 12.3%--in itself more than a percentage point
above the long-term average return from common stocks. Small-cap stocks also
fared well overall, as illustrated by the 22.4% increase of the Russell 2000
Index.  Small-company technology issues were the most glaring exception,
mustering a gain in 1997 of just 1.1%.

U.S. FIXED-INCOME MARKETS

In a year characterized by exceptionally low inflation, interest rates fell,
providing investors with very attractive total returns.  The Lehman Aggregate
Bond Index, for example,





                                       4
<PAGE>   7
posted a total return of 9.7% for 1997, comprising 7.2% in income return and
2.5% in capital appreciation. The decline in rates can be attributed largely to
better-than-expected reports about the inflation rate. Early in the year,
economists were projecting a 2.9% increase in the Consumer Price Index (CPI)
during 1997. In March, the Federal Reserve grew sufficiently concerned to boost
interest rates by 0.25% in an effort to temper economic growth and thereby ward
off inflation. By year-end, however, the worries seemed to have been
unnecessary, as the actual CPI increase was a mere 1.7%--its smallest increase
since 1986.

     The bond market gradually gathered strength during the year as investors
grew more confident that four seemingly strange bedfellows--strong economic
growth, reasonable inflation, low unemployment, and stable wage growth--would
continue to coexist peacefully. In the fourth quarter, the market also was
bolstered by the "flight to quality" among investors concerned about Asia's
problems. Overall, the longest-maturity issues benefited most from the decline
in interest rates. The yield on the 30-year U.S.  Treasury bond closed the year
at 5.92%, compared with 6.64% on December 31, 1996. Falling rates flattened the
yield curve considerably: Only 0.57% separated the yield on Treasury bills from
that on the 30-year issue, down from a spread of 1.47% at the end of 1996.

     The best-performing sector in 1997 was long-term Treasuries, as
illustrated by the 15.1% return of the Lehman Long U.S.  Treasury Index.
Investors in lower-quality securities also fared well, with the Lehman High
Yield Bond Index generating a 12.8% gain. The strength of the economy, together
with the lack of inflationary pressure, created an ideal environment for junk
bonds.

INTERNATIONAL EQUITY MARKETS

Arguably, investors' greatest disappointments were in international
markets--and, of course, Asian markets in particular. During the year, the
Morgan Stanley Capital International (MSCI) Pacific Index declined by 25.7% in
U.S. dollar terms; the index fell 20.7% in the fourth quarter alone. Among
individual markets, the fiscal year saw sharp declines (in U.S. dollar terms)
in Japan, down 23.6% (including a 19.7% drop in the fourth quarter); Thailand,
down 76.8%; and Malaysia, down 68.1%. The general slump in Asian markets began
in midsummer with currency devaluations by a number of countries.

     By contrast, the European markets continued to provide U.S. investors with
solid returns, although they, too, stumbled in late October and subsequently
recovered. The MSCI Europe Index posted a gain of 23.7% for the 12 months. The
robust character of the European markets reflected strong corporate earnings
and optimism that the European Monetary Union would provide a solid framework
for future fiscal responsibility and economic growth.

REPORT FROM THE ADVISER

We are pleased to report on our investment results for the year ended December
31, 1997. The Portfolio's return of 35.6% exceeded those of the unmanaged S&P
500 Index and the average value (growth and income) mutual fund. Indeed, your
Portfolio's return in 1997 surpassed those earned by more than 90% of the funds
in Morningstar's growth and income fund category, a record we have achieved in
each of the four periods presented in the table at right.

     Large-capitalization stocks were the market's clear leaders both in the
fourth quarter of 1997 and for the full year. The largest 25 stocks in the S&P
500 Index earned a total return of 4.1% during the fourth quarter, while the
entire Index returned 2.9%. For the full year, the largest 25 stocks
outperformed the entire Index by more than 5 percentage points. Most actively
managed stock portfolios have trouble matching the Index when its largest
components are so heavily influencing its gains. By the same token, when the
largest components of the Index are laggards, managed portfolios typically
perform better than the Index.

     Despite the dominance of the very largest stocks, with the implied
challenge for a managed fund such as your Portfolio, we were able to outperform
the Index in 1997 because of our analytical approach to selecting stocks.

     We build and maintain the Portfolio by making a series of analytical
measurements on a large universe of securities. In attempting to identify those
stocks that are undervalued, we use three basic types of measures:

     - Fundamental momentum measures. These analytical yardsticks are employed
to identify companies whose business and near-term business prospects are
relatively strong.

     - Relative value measures. These quantify the attractiveness of a stock's
price in relation to such financial measures as book value, sales, or earnings.

     - Future cash flow. These analytical measures identify likely favorable
payoffs in terms of future earnings and dividends for an investment made today.

     Vanguard Growth and Income Portfolio uses these measures of value in
developing investment strategies. Applying a variety of yardsticks to security
selection will, we believe, help us to deliver consistent results. The
long-term performance comparisons above lend credence to our view. Each method
of determining value contributed to our strong results during 1997, helping us
to surpass both our average peer and the unmanaged Index.

     We emphasize a point that we try to make in every shareholder report: We
are long-term investors. We do not expect to be near the top of a list of
equity funds for every short-term period of comparison. We are, of course,
happy when this is the case; however, our goal is to be at the top of these
lists over the long term.





                                       6
<PAGE>   9
Our investors should have a long-range perspective and a desire for exposure to
the stock market. We expect to be fully invested in equities as a matter of
investment policy. Our goal is to provide superior equity returns over extended
periods.

     Our outlook is positive. We have demonstrated an ability to outperform
most active managers in a period that has been difficult for active management.
In periods when active managers generally outperform indexing, we believe that
we will outperform to a meaningful degree both our peers and indexing
alternatives.

     We believe that our past success illustrates the effectiveness of the
Franklin game plan, which is to seek to win while avoiding periods of major
underperformance versus our benchmark. Our goal with your assets is to be

INVESTMENT PHILOSOPHY

The Portfolio 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.

BETA. A measure of the magnitude of a portfolio's past share-price fluctuations
in relation to the ups and downs of the overall market (or appropriate market
index). The market (or index) is assigned a beta of 1.00, so a portfolio with a
beta of 1.20 would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%.

CASH RESERVES. The percentage of a portfolio's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing securities. This
figure does not include cash invested in futures contracts to simulate stock
investment.

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

EXPENSE RATIO. The percentage of a portfolio'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 portfolio's net assets represented by
stocks or American Depositary Receipts of companies based outside the United
States.

INVESTMENT FOCUS. This grid indicates the focus of a portfolio in terms of two
attributes: market capitalization (large, medium, or small) and relative
valuation (growth, value, or a blend).

MEDIAN MARKET CAP. The midpoint of market capitalization (market price x shares
outstanding) of the stocks in a portfolio. Half the stocks in the portfolio
have higher market capitalizations and half lower.

NUMBER OF STOCKS. An indicator of diversification. The more stocks a portfolio
holds, the more diversified it is and the more likely to perform in line with
the overall stock market.

PRICE/BOOK RATIO. The share price of a stock divided by its net worth, or book
value, per share. For a portfolio, 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 portfolio, 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 portfolio's past returns can be explained
by the returns from the overall market (or its benchmark index). If a
portfolio's total return were precisely synchronized with the overall market's
return, its R-squared would be 1.00. If a portfolio's returns bore no
relationship to the market'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 portfolio, the weighted average return
on equity for the companies whose stocks it holds.

SECTOR DIVERSIFICATION. The percentages of a portfolio's common stocks that
come from each of the major industry groups that compose the stock market.

TEN LARGEST HOLDINGS. The percentage of net assets that a portfolio has
invested in its ten largest holdings. (The average for stock mutual funds is
about 30%.) As this percentage rises, a portfolio's returns are likely to be
more volatile because they are more dependent on the fortunes of a few
companies.

TURNOVER RATE. An indication of trading activity during the past year.
Portfolios with high turnover rates incur higher transaction costs and are more
likely to distribute capital gains (which are taxable to investors).

YIELD. A snapshot of a portfolio's income from interest and dividends. The
yield, expressed as a percentage of the portfolio'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
dividends paid on stocks in the index.

PERFORMANCE SUMMARY

Growth and Income Portfolio

All of the data on this page represent past performance, which cannot be used
to predict future returns that may be achieved by the Portfolio. Note, too,
that both share price and return can fluctuate widely, so an investment in the
Portfolio could lose money.

FINANCIAL STATEMENTS

December 31, 1997

STATEMENT OF NET ASSETS

This Statement provides a detailed list of the Portfolio'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, preferred
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 Portfolio's Net Assets. Finally, Net Assets are divided by the outstanding
shares of the Portfolio 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 Portfolio's net assets on both a dollar and per-share
basis. 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 Portfolio had available to distribute to shareholders as income
dividends or capital gains as of the statement date. 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 Portfolio's
investments and their cost, and reflects the gains (losses) that would be
realized if the Portfolio were to sell all of its investments at their
statement-date values.

STATEMENT OF OPERATIONS

This Statement shows dividend and interest income earned by the Portfolio
during the reporting period, and details the operating expenses charged to the
Portfolio. These expenses directly reduce the amount of investment income
available to pay to shareholders as dividends. This Statement also shows any
Net Gain (Loss) realized on the sale of investments, and the increase or
decrease in the Unrealized Appreciation (Depreciation) on investments during
the period. If the Portfolio invested in futures contracts during the period,
the results of these investments are shown separately.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the Portfolio'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 Portfolio'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 amount shareholders invested in the Portfolio, either by purchasing
shares or by reinvesting distributions, as well as the amounts redeemed. The
corresponding numbers of Shares Issued and Redeemed are shown at the end of the
Statement.

FINANCIAL HIGHLIGHTS

This table summarizes the Portfolio's investment results and distributions to
shareholders on a per-share basis. It also presents the Portfolio's 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 Portfolio's
net income and total returns from year to year; the relative contributions of
net income and capital gains to the Portfolio's total return; how much it costs
to operate the Portfolio; and the extent to which the Portfolio 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 Portfolio for one year. Finally, the table lists the Portfolio's Average
Commission Rate Paid, a disclosure required by the Securities and Exchange
Commission beginning in 1996. This rate is calculated by dividing total
commissions paid on portfolio securities by the total number of shares
purchased and sold on which commissions were charged.

NOTES TO FINANCIAL STATEMENTS

Vanguard Growth and Income Portfolio (formerly Vanguard Quantitative
Portfolios) is registered under the Investment Company Act of 1940 as a
diversified open-end investment company, or mutual fund.

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

    1. SECURITY VALUATION: Securities listed on an exchange are valued at the
latest quoted sales prices as of the close of trading on the New York Stock
Exchange (generally 4:00 p.m. Eastern time) on the valuation date; such
securities not traded on the valuation date are valued at the mean of the
latest quoted bid and asked prices. Securities not listed on an exchange are
valued at the latest quoted bid prices. Bonds, and temporary cash investments
acquired more than 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. FEDERAL INCOME TAXES: The Portfolio 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.

    3. REPURCHASE AGREEMENTS: The Portfolio, 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. FUTURES: The Portfolio uses S&P 500 Index futures contracts to a limited
extent, with the objectives of maintaining full exposure to the stock market
while maintaining liquidity. The Portfolio 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 Portfolio 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).

    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.

B.  Franklin Portfolio Associates provides investment advisory services to the
Portfolio for a fee calculated at an annual percentage rate of average net
assets. The basic fee is subject to quarterly adjustments based on performance
relative to the S&P 500 Index. For the year ended December 31, 1997, the
advisory fee represented an effective annual basic rate of 0.13% of the
Portfolio's average net assets before a decrease of $244,000 (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 Portfolio under methods approved by the Board of Directors. At December
31, 1997, the Portfolio had contributed capital of $138,000 to Vanguard
(included in Other Assets), representing 0.6% of Vanguard's capitalization. The
Portfolio's Directors and officers are also Directors and officers of Vanguard.

    Vanguard has asked the Portfolio's investment adviser to direct certain
portfolio trades, subject to obtaining the best price and execution, to brokers
who have agreed to rebate to the Portfolio part of the commissions generated.
Such rebates are used solely to reduce the Portfolio's administrative expenses.
For the year ended December 31, 1997, these arrangements reduced the
Portfolio's expenses by $131,000 (0.01% of average net assets).

D.  During the year ended December 31, 1997, the Portfolio purchased
$1,443,991,000 of investment securities and sold $1,058,763,000 of investment
securities, other than U.S. government securities and temporary cash
investments.

E.  At December 31, 1997, net unrealized appreciation of investment securities
for financial reporting and federal income tax purposes was $496,483,000,
consisting of unrealized gains of $522,701,000 on securities that had risen in
value since their purchase and $26,218,000 in unrealized losses on securities
that had fallen in value since their purchase.

    At December 31, 1997, the aggregate settlement value of open futures
contracts expiring in March 1998 and the related unrealized appreciation were:

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and
Board of Directors of
Vanguard Growth and Income Portfolio

In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Vanguard Growth and Income Portfolio (formerly Vanguard Quantitative
Portfolios, hereafter referred to as the "Portfolio") at December 31, 1997, the
results of its operations for the year then ended, the changes in its net
assets for each of the two years in the period then ended and the financial
highlights for each of the five years in the period then ended, in conformity
with generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Portfolio's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at December 31, 1997 by
correspondence with the custodian and the application of alternative auditing
procedures where securities purchased had not been settled, provide a
reasonable basis for the opinion expressed above.

SPECIAL 1997 TAX INFORMATION (UNAUDITED) FOR VANGUARD GROWTH AND INCOME
PORTFOLIO

This information for the fiscal year ended December 31, 1997, is included
pursuant to provisions of the Internal Revenue Code.

     The Portfolio designates $143,763,000 as capital gains dividends (from net
long-term capital gains), of which $93,832,000 was distributed to shareholders
in December 1997 and $49,931,000 will be distributed in March 1998. Of the
$143,763,000 capital gain dividends, the Portfolio designates $95,905,000 as a
20% rate gain distribution.

     For corporate shareholders, 26.4% of investment income (dividend income 
plus short-term gains, if any) qualifies for the dividends-received deduction.
