FELLOW SHAREHOLDERS:

     Two roads  diverged in a wood,  and I--I took the one less traveled by, and
     that has made all the difference.

I can think of no better  words than those of Robert Frost to begin this special
letter to our shareholders,  who have placed such extraordinary  trust in me and
in Vanguard  over the past quarter  century.  When the firm was founded 25 years
ago,  we  deliberately  took a new road to  managing a mutual  fund  enterprise.
Instead of having the funds controlled by an outside management company with its
own  financial  interests,  the  Vanguard  funds--there  were  only  11 of  them
then--would be controlled by their own  shareholders and operate solely in their
financial interests.  The outcome of our unprecedented  decision was by no means
certain. We described it then as "The Vanguard Experiment."
   Well, I guess it's fair to say it's an experiment no more. During the past 25
years,  the  assets we hold in  stewardship  for  investors  have  grown from $1
billion  to more  than  $500  billion,  and I believe  that our  reputation  for
integrity,  fair-dealing,  and sound investment  principles is second to none in
this  industry.  Our  staggering  growth--which  I  never  sought--has  come  in
important part as a result of the simple investment ideas and basic human values
that are the foundation of my personal philosophy.  I have every confidence that
they  will  long  endure at  Vanguard,  for they are the  right  ideas and right
values, unshakable and eternal.
   While Emerson  believed that "an institution is the lengthened  shadow of one
man," Vanguard today is far greater than any  individual.  The Vanguard crew has
splendidly  implemented  and  enthusiastically  supported our founding ideas and
values, and deserves the credit for a vital role in forging our success over the
years.  It is a  dedicated  crew of fine human  beings,  working  together in an
organization  that is well prepared to press on regardless long after I am gone.
Creating and leading this  enterprise has been an exhilarating  run.  Through it
all,  I've taken the kudos and the blows  alike,  enjoying  every  moment to the
fullest,  and even getting a second chance at life with a heart transplant three
years ago. What more could a man ask?
   While I shall no longer be serving on the  Vanguard  Board,  I want to assure
you that I will remain  vigorous and active in a newly  created  Vanguard  unit,
researching the financial markets, writing, and speaking. I'll continue to focus
whatever  intellectual  power and  ethical  strength  I possess on my mission to
assure that mutual fund investors everywhere receive a fair shake. In the spirit
of Robert Frost:

   But I have promises to keep, and miles to go before I sleep,  and miles to go
before I sleep.

         You have given me your  loyalty and  friendship  over these long years,
and I deeply  appreciate  your  thousands of letters of support.  For my part, I
will continue to keep an eagle eye on your  interests,  for you deserve no less.
May God bless you all, always.

REPORT FROM THE CHAIRMAN

Vanguard Convertible  Securities Fund posted a terrific gain of 24.8% during the
fiscal year ended  November 30,  1999,  rebounding  from a -2.2%  decline in the
prior year. Bond prices  fell--reflecting  rising interest  rates--while  stocks
continued to bound higher.
     The table at right  presents the fund's total return  (capital  change plus
reinvested dividends) compared with those of the average convertible  securities
fund and our unmanaged  benchmark,  the Credit  Suisse First Boston  Convertible
Securities  Index. We also present the returns of two indexes as proxies for the
broad market environment:  for stocks, the Wilshire 5000 Total Market Index; for
bonds,  the Lehman  Brothers  Aggregate Bond Index.  As shown in the table,  our
fund's  return  topped  that  of its  average  peer  but  lagged  the  unmanaged
convertibles index.

     Our total return is based on an increase in net asset value from $11.10 per
share on November  30, 1998,  to $13.18 per share on November  30, 1999,  and is
adjusted for dividends totaling $0.57 per share paid from net investment income.
The fund's  dividend  yield was 3.16% on November  30,  down about 1  percentage
point from the end of fiscal 1998.

FINANCIAL MARKETS IN REVIEW
The 12-month period ended November 30 featured plenty of positive economic news,
as well as plenty of concern over how much longer the good times can roll before
inflation  begins to  accelerate.  The U.S.  economy's  expansion  continued  to
display remarkable staying  power--inflation-adjusted  economic output rose 4.3%
from the third  quarter of 1998 to the third  quarter of 1999,  and the nation's
unemployment rate was at the lowest point in three decades.  Overseas  economies
also picked up steam.  Despite  heightened  business  activity and a significant
rise in energy prices,  inflation was moderate:  Consumer prices  increased 2.6%
during our fiscal year.
     Of course,  financial markets seek to look ahead, not behind.  And a belief
that higher  inflation  could not be far off was  reflected  in a steady rise in
interest  rates during the fiscal year.  The yield of the 30-year U.S.  Treasury
bond ended the fiscal year at 6.29%, up 123 basis points from its starting point
of 5.06% on November 30, 1998.  The Federal  Reserve  Board aided the uptrend by
raising its target for  short-term  interest  rates three times by a total of 75
basis points (0.75 percentage  point) in an attempt to slow the economy and head
off inflation.
     Despite rising interest rates,  stock market averages managed an impressive
advance,  albeit an uneven one. The entire U.S. stock market,  as represented by
the Wilshire 5000 Index,  advanced 22.4%,  but much of the gain was concentrated
in a small  number of stocks.  Technology  companies  powered  the  ascent--tech
stocks within the S&P 500 Index gained 66% as a group. The return of the overall
S&P 500, which is dominated by

                                       1
<PAGE>

large-capitalization stocks, exceeded 20% for the fifth consecutive fiscal year.
Many value-oriented stocks were left far behind, however. The S&P's value stocks
gained 12.5%,  less than half the 28.5% return for growth stocks.  The disparity
was  astonishing  within the small-cap  Russell 2000 Index,  where growth stocks
gained 32.7% and value stocks declined -1.4%.
     Amid rising interest  rates--which force bond prices lower--the bond market
suffered its worst year since 1994.  Price declines were most severe among bonds
with long-term maturities.  For instance,  the price of long-term Treasury bonds
fell by more than 13%. The acute sensitivity of long-term bonds to interest rate
shifts  reflects the fact that investors in such  securities  receive their cash
flow over many  years.  Higher  interest  rates  reduce the  "present  value" of
far-off dividend or principal payments. This phenomenon was strikingly displayed
during the fiscal  year:  The Lehman  Aggregate  Bond Index,  a benchmark of the
overall market for taxable  investment-grade  bonds, had a total return of zero,
with its interest income of 6.2% entirely offset by a price decline of -6.2%.
     On balance,  convertible bonds and preferred stocks--hybrid securities that
exhibit characteristics of both equities and bonds--advanced impressively during
the period,  earning  returns that were slightly  higher than those of large-cap
stocks and far in excess of returns on bonds.

FISCAL 1999 PERFORMANCE OVERVIEW
Vanguard  Convertible  Securities Fund enjoyed an excellent fiscal 1999, gaining
24.8%.  However,  the road to this result was a bit bumpy.  After sharp advances
early in the fiscal year, the convertibles  market cooled in February and March.
This pattern then repeated  itself;  a spring rally was followed by a summertime
slump.  The good times  resumed in the period's  final two months,  and the fund
returned 10.9% from the end of September through November.  Our full-year return
was 0.9 percentage point higher than the 23.9% earned by the average convertible
securities  fund, but 5.8 percentage  points lower than the 30.6% gain of the CS
First Boston Convertibles Index.
     Our margin over our average peer--though  modest--was  notable,  because we
held no stocks  during the  period.  The  average  convertible  securities  fund
invested  about  10%  of its  assets  in  stocks.  Though  Vanguard  Convertible
Securities Fund  periodically  retains a common stock produced by the conversion
of a corporate bond or preferred  stock, our adviser  generally  manages risk by
shunning  stocks  and  selling  convertibles  once they begin to trade like pure
equities. The convertible corporate bonds and preferred stocks emphasized by our
fund are true hybrid securities--they  provide more income than stocks and offer
greater potential for price appreciation than bonds.
     Our  shortfall  versus  the  CS  First  Boston  Convertibles  Index  can be
explained by the  benchmark's  concentration  in a few issues that soared during
the fiscal year. For example, the index's top holding--a  technology issue whose
price increased  roughly tenfold during the period--made up 6.1% of the index on
November 30. The largest holding in your fund  represented  half that weighting,
just 3.2% of the fund's net assets at year-end.  More information on the amazing
runup in a few convertibles can be found on page 7 in the letter from the fund's
adviser,  Oaktree  Capital  Management,   LLC,  which  has  managed  the  fund's
investments for the past three years.

LONG-TERM PERFORMANCE OVERVIEW
The table on the next page  presents the returns  during the past decade for the
Convertible Securities Fund, our average peer, and the unmanaged CS First Boston
Convertibles Index.

It also shows the value of hypothetical  $10,000  investments made ten years ago
in the fund and its benchmarks.  Assuming the reinvestment of income and capital
gains  distributions,  a $10,000  investment in the Convertible  Securities Fund
would have grown to $29,799,  or $1,181  less than the  $30,980  that would have
accumulated  in the average  convertible  fund.  Our return  trailed that of the
index by a wider margin, 1.7 percentage points annually.

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

     Our fund is  disciplined  in its  pursuit of issues  that offer  attractive
yields and above-average growth potential.  As always, our adviser's efforts are
aided by our low expense ratio (annual  expenses as a percentage of net assets).
In fiscal 1999,  our expense  ratio was 0.55%,  more than 0.9  percentage  point
below the 1.48% expense  ratio of the average  convertible  securities  fund. In
practice,   our  advantage  means  that  competing  funds  must  earn  a  higher
return--perhaps by taking greater risks--to offset their cost disadvantage.

IN SUMMARY

When one asset class  performs so well, as stocks did again in fiscal 1999,  and
another  performs  poorly,  as did  bonds,  it  would be easy to  conclude  that
diversification is not worthwhile. That conclusion would be dead wrong.
     At  Vanguard,  we  continue  to believe  that most  investors  should  hold
balanced  portfolios of stock funds,  bond funds, and short-term  reserves.  For
some investors,  convertible  securities also can play a worthwhile role. All of
these securities should be held in proportions suitable for each person's unique
investment  goals,  time horizon,  and  tolerance for risk.  With such a plan in
place, investors are well advised to "stay the course."

A NOTE OF THANKS TO OUR FOUNDER
- --------------------------------------------------------------------------------
As you may have read on the inside  cover of our report,  our  founder,  John C.
Bogle,  is retiring  December  31, 1999,  as Senior  Chairman of our Board after
nearly 25 years of devoted  service to Vanguard and our  shareholders.  Vanguard
investors  have Jack to thank for  creating a truly  mutual  mutual fund company
that operates solely in the interest of its fund  shareholders.  And mutual fund
investors  everywhere have benefited from his energetic  efforts to improve this
industry.  Finally, on a personal note, I am forever grateful to Jack for giving
me the opportunity to join this great company in 1982.

A REPORT ON YOUR FUND'S AFTER-TAX RETURNS
Beginning  with this annual  report,  Vanguard is pleased to provide a review of
the Convertible  Securities  Fund's after-tax  performance.  The figures on this
page demonstrate the considerable impact that federal income taxes can have on a
fund's return--an important  consideration for investors who own mutual funds in
taxable  accounts.  While the pretax return is most often used to tally a fund's
performance,   the  fund's  after-tax  return,   which  accounts  for  taxes  on
distributions of capital gains and income dividends,  is a better representation
of the return that many investors actually received.  If you own the Convertible
Securities  Fund in a  tax-deferred  account  such as an  individual  retirement
account or a 401(k),  this  information does not apply to you. Such accounts are
not subject to current taxes.
     The table below presents the pretax and after-tax returns for your fund and
an appropriate peer group of mutual funds. Two things to keep in mind:
     o The after-tax return calculations use the top federal income tax rates in
effect at the time of each  distribution.  The tax burden,  therefore,  would be
somewhat  less, and the after-tax  return  somewhat more, for those in lower tax
brackets.
     o The peer funds' returns are provided by Morningstar,  Inc.  (Elsewhere in
this report,  returns for comparable mutual funds are derived from data provided
by Lipper Inc., which differ somewhat.)

*Based on data from Morningstar, Inc.
</TABLE>

     As you can see, the  Convertible  Securities  Fund's pretax total return of
24.8% for the 12 months ended  November 30, 1999, was reduced by taxes to 22.4%.
In other words,  for  investors in the highest tax  bracket,  the fund's  pretax
return was cut by 2.4 percentage points. In comparison,  the 22.4% return of the
average convertible  securities fund was reduced by taxes to 19.7%, a difference
of 2.7 percentage  points.  Over longer time periods,  the fund delivered  lower
returns than its average peer, both before and after taxes.
     We stress that because many interrelated  factors affect how tax-friendly a
fund may be,  it's very  difficult  to  predict  tax  efficiency.  A fund's  tax
efficiency  can be influenced by its turnover  rate,  the types of securities it
holds,  the accounting  practices it uses when selling shares,  and the net cash
flow it receives.
     Finally, it's important to understand that our calculation does not reflect
the  effect  of your own  investment  activities.  Specifically,  you may  incur
additional capital gains  taxes--thereby  lowering your after-tax return--if you
decide to sell all or some of your shares.

A  NOTE  ABOUT  OUR   CALCULATIONS:   Pretax  total  returns   assume  that  all
distributions   received  (income  dividends,   short-term  capital  gains,  and
long-term  capital  gains) are  reinvested  in new shares,  while our  after-tax
returns assume that  distributions  are reduced by any taxes owed on them before
reinvestment.  When  calculating  the taxes due, we used the highest  individual
federal  income  tax  rates at the time of the  distributions.  Those  rates are
currently 39.6% for dividends and short-term capital gains and 20% for long-term
capital gains. State and local income taxes were not considered. The competitive
group returns provided by Morningstar are calculated in a manner consistent with
that used for Vanguard funds.

THE MARKETS IN PERSPECTIVE
YEAR ENDED NOVEMBER 30, 1999

Strong economic  expansion sent global stock markets charging higher but dealt a
blow to bond  prices  during  the fiscal  year  ended  November  30,  1999.  The
powerhouse U.S. economy led the global growth parade, joined by Asian, European,
and Latin American economies that had slumped or stagnated in 1998.
     Interest  rates rose sharply as investors  and monetary  policymakers  grew
increasingly  worried that such strong  economic growth would cause inflation to
surge.  Although the rise in rates caused bond prices to fall,  it only tempered
the stock market's advance.

U.S. STOCK MARKETS
Against  the  backdrop  of a booming  economy,  U.S.  companies  reported  solid
increases in earnings  during the fiscal  year.  The  nation's  economic  output
increased  at an  inflation-adjusted  rate of 4.3%--a very rapid pace for such a
large, mature economy.  Consumer spending, which accounts for roughly two-thirds
of economic activity, powered the expansion.  Americans spent freely, encouraged
by rising  wealth  from a long  bull  market,  a hot job  market,  and  climbing
incomes.

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

     The stock  market,  as measured by the  Wilshire  5000 Index,  gained 22.4%
overall.  For a change,  mid-capitalization  and small-cap stocks outpaced their
large-cap  brethren.  The large-cap S&P 500 Index,  which accounts for more than
75% of the U.S. stock  market's  total value,  gained 20.9% during the year; the
rest of the market (as measured by the Wilshire 4500 Index) gained 29.0%.
     Increasingly  optimistic  expectations for future  corporate  earnings more
than offset the negative  effects of rising  interest  rates during fiscal 1999.
Higher rates often hurt stock prices because many investors use current rates to
discount the value of a stock's projected earnings and dividends. The higher the
interest rate, the more future earnings are  discounted,  and the less investors
will pay for the stock now.
     Because of a  remarkable  surge in prices  for  technology  stocks,  growth
stocks again  outperformed value stocks during the past year. Within the S&P 500
Index, growth stocks--characterized by high prices in relation to earnings, book
value, and  dividends--recorded  a 28.5% return,  16 percentage points above the
12.5% return for value  stocks.  The disparity was even greater in the small-cap
segment of the market;  growth stocks  within the  small-cap  Russell 2000 Index
gained 32.7%, while value stocks posted a -1.4% return.
     Technology  stocks within the S&P 500 Index gained 66%.  QUALCOMM posted an
eye-popping  1,200% return, and a number of  computer-related  stocks doubled or
tripled in

price,  including Sun  Microsystems  (+257%),  Apple  Computer  (+206%),  Oracle
(+197%), Gateway (+172%), Texas Instruments (+152%), and Cisco Systems (+136%).
     Big gains for wireless  telecommunications  and cable-TV stocks powered the
utilities  category  to an overall  gain of nearly  28%.  The  producer-durables
group, which includes some technology-related  manufacturers as well as aircraft
and  equipment  makers,  gained 27%. Oil  exploration  and service  firms in the
"other energy"  category  posted a 26% return,  assisted by a jump in prices for
oil and natural gas.
     The year's worst-performing sector was consumer staples (down nearly -12%).
This group suffered as severe price  competition and a stronger dollar in Europe
crimped profits for many food and beverage makers, and the specter of litigation
costs caused tobacco stocks to slump. The auto &  transportation  group declined
- -2% overall, with airline stocks hurt by rising prices for jet fuel.

U.S. BOND MARKETS
Stock  investors  may cheer a  fast-growing  economy,  but rapid growth tends to
worry   bond   investors.   Early  in  the   fiscal   year,   inflation   seemed
dormant--plunging  oil prices had taken  commodity  price  indexes to the lowest
point in a  quarter-century.  But as the  world  economy  began  hitting  on all
cylinders,  the bond  market  feared that a minuscule  U.S.  unemployment  rate,
rising  commodity  prices,  and capacity  constraints  would cause  inflation to
accelerate.  Although oil prices were up nearly 150% during the fiscal year, the
overall  price level,  as measured by the Consumer  Price Index,  increased by a
moderate 2.6%.
     The Federal Reserve Board, anticipating price pressures, abandoned its bias
toward easier monetary  policy,  and by mid-year was boosting  interest rates to
try to  throttle  back the  economic  engines.  The bond market was ahead of the
Fed--interest  rates began rising sharply in February.  By fiscal year-end,  the
yield of 30-year U.S. Treasury bonds had risen 1.23 percentage points (123 basis
points) to 6.29%. The 10-year Treasury note's yield rose 148 basis points,  from
4.71% to  6.19%.  The rise in  short-term  rates  was more  restrained;  3-month
Treasury bill yields were up 82 basis points to 5.30% at fiscal year-end.
     Bond prices fall when interest  rates rise,  and long-term  bond prices are
most sensitive to changing  rates.  Long-term  Treasury bond prices fell by more
than -13%, resulting in total returns of -8%. The Lehman Aggregate Bond Index, a
measure of the  overall  taxable  bond  market,  which has an  intermediate-term
structure  on average,  broke even on the year,  as interest  income of 6.2% was
offset by price declines.  The damage to municipal bond prices was not as severe
as for Treasuries,  and the intermediate-term Lehman 7 Year Municipal Bond Index
recorded a price decline of -3.7% and a total return of 0.5%.

INTERNATIONAL STOCK MARKETS
International  markets had a strong year,  with European stocks gaining 21.9% in
local-currency  terms  and  Pacific-region   stocks  advancing  30.2%.  However,
currency effects significantly altered the returns to U.S.-based investors.  The
U.S.  dollar rose in value  against most  European  currencies  but fell sharply
against the Japanese  yen. As a result,  returns from Europe  plunged to 9.8% in
dollar terms while returns from the Pacific soared to 51.0%.
     Overall,  U.S. investors earned 21.4% in the major developed  international
markets,  as  measured  by the  Morgan  Stanley  Capital  International  Europe,
Australasia,  Far East (EAFE)  Index.  The bull markets in most nations  stemmed
from renewed  optimism that economic growth would continue to accelerate.  Japan
and the rest of Asia,  which were hit hardest by currency and economic crises in
1997 and 1998, saw the biggest stock gains.
     Emerging  markets,  as measured by the Select Emerging  Markets Free Index,
gained 37.1% in  U.S.-dollar  terms,  as investors  regained an appetite for the
considerable risks of smaller markets.

REPORT FROM THE ADVISER

Our  latest  fiscal  year ended on an  ebullient  note as  Vanguard  Convertible
Securities Fund's technology and  telecommunications  holdings propelled it to a
very strong finish.  Fueled by strong price  advances for  underlying  equities,
convertibles  in general  and the fund in  particular  had one of the best years
ever.  Interest  rates on corporate  debt rose only  moderately,  and were not a
major impediment.  For the year ended November 30, 1999, the fund's 24.8% return
handily  outpaced  those of the S&P 500 Index  (20.9%),  the Russell  2000 Index
(15.7%), and most fixed-income benchmarks.
     Although the fund's return was excellent in an absolute  sense,  it trailed
the 30.6%  return of our  primary  benchmark--the  Credit  Suisse  First  Boston
Convertible  Securities Index. This index's  extraordinary return was due to the
performance  of just a few big  holdings,  which  behaved  like  stocks  and had
stellar  gains.  As we have discussed in previous  letters,  the fund focuses on
securities that have both equity and fixed-income characteristics,  and does not
hold convertibles after they have become pure equity substitutes.
     An example of a security  that has become a pure equity  substitute  is the
QUALCOMM 5.75%  convertible  preferred,  which sold for $50 in February 1997. It
now sells above $550 and yields just over 0.5%.  From here, the  convertible can
only mirror the movement of QUALCOMM's common stock. This offering of preferred,
when issued,  had a market value of $660 million.  Now, thanks to the phenomenal
performance of the  underlying  stock,  its value stands at $6.7 billion.  After
rising 291% during the fourth fiscal quarter and an  unbelievable  1,061% during
fiscal 1999, this single issue now represents 6.1% of the Convertible Securities
Index. Because of the incredible performance of QUALCOMM and a few other stocks,
a large  proportion of the index now is concentrated  in a few very  equity-like
securities. In fact, the top ten securities, or just 3% of the 330 issues in the
index, have a market  capitalization of $20.8 billion and account for 23% of the
index's value.
     En route to its  impressive  return for the fiscal year,  the  convertibles
market was volatile--due mainly to the changing  macroeconomic  environment,  in
which  generally  positive  corporate  earnings,  fluctuating  oil  prices,  and
interest  rate  gyrations  all  affected   convertible  security  valuation  and
performance.
- --------------------------------------------------------------------------------
INVESTMENT PHILOSOPHY
The adviser  believes  that a reasonable  level of current  income and long-term
growth in capital can be achieved by investing in a broadly diversified group of
convertible  securities that provide  attractive  combinations of current income
and  potential  for price  appreciation  from their  convertibility  into common
stock.
- --------------------------------------------------------------------------------
     Robust  earnings and a resolutely  upbeat market  psychology  pushed stocks
higher,   which  helped  prices  of  convertibles,   especially  those  tied  to
high-flying technology and telecommunication stocks. For downside protection, we
look  to  each   convertible's   "investment   value"  (i.e.,  its  value  as  a
nonconvertible  fixed-income  security).  During the fiscal  year,  the  average
convertible's  investment value generally weakened because of the rise in market
interest  rates.  At the same time, as the price of the average  convertible was
pushed higher by the gain of its underlying  shares, its premium over investment
value  rose  sharply.   What  really  determined  any  convertible   portfolio's
performance  during this period was, first, its exposure to the tech and telecom
sectors,

                                       7
<PAGE>

and then whether it emphasized  holdings sensitive to equity prices as
opposed to those whose fixed-income characteristics offered downside protection.
Rather than retain appreciating positions (at the cost of allowing our portfolio
to become more equity-sensitive),  we followed our usual practice of scaling out
of rising  investments.  By doing this, we maintained  our focus on the downside
risk of individual positions and the overall portfolio.
     Another  factor  that  influenced  the  convertible  market in 1999 was the
strength of the new-issue  market,  which saw innovative  structures,  a diverse
list of issuers, some very large issues, and "overnight"  convertible offerings.
During the year, a total of $33.6 billion in new paper was issued, compared with
$33.3 billion in 1998.  Attractive new issues that we purchased  during the past
few quarters included  convertibles from Nextel,  LSI Logic,  Interpublic Group,
Cox  Communications,  and Safeguard  Scientifics.  Liquidity in the  convertible
market remains good, and we remain focused on the larger issues,  as measured by
market capitalization.
     The fund is well  diversified,  with  approximately 70 individual  holdings
representing  a wide variety of  industries.  At the close of the fiscal year on
November 30, our heaviest  industry emphasis was on the  telecommunications  and
technology sectors. In terms of securities,  our principal concentration remains
on convertible bonds with moderate  conversion  premiums and maturity dates five
to ten years out.  Given the very strong gains in many of our holdings,  we have
recently  reduced  positions in several  names that have become  equity-like  in
their characteristics.  As always, when purchasing securities we look for a good
balance of upside potential and downside protection.

AVERAGE COUPON. The average interest rate paid on the securities held by a fund.
It is expressed as a percentage of face value.

AVERAGE  DURATION.  An  estimate  of how much a bond  fund's  share  price  will
fluctuate in response to a change in interest  rates. To see how the price could
shift,  multiply the fund's  duration by the change in rates.  If interest rates
rise by one percentage point, the share price of a fund with an average duration
of five years  would  decline  by about 5%. If rates  decrease  by a  percentage
point, the fund's share price would rise by 5%.

AVERAGE QUALITY.  An indicator of credit risk, this figure is the average of the
ratings assigned to a fund's securities holdings by credit-rating  agencies. The
agencies make their  judgment after  appraising an issuer's  ability to meet its
obligations.  Quality is graded on a scale,  with Aaa or AAA indicating the most
creditworthy bond issuers.

AVERAGE WEIGHTED MATURITY. The average length of time until securities held by a
fund reach maturity (or are called) and are repaid.  In general,  the longer the
average  weighted  maturity,  the more a fund's  share price will  fluctuate  in
response to changes in market interest rates.

BETA. A measure of the magnitude of a fund'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 fund 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%.

                                       11
<PAGE>

CASH  RESERVES.  The  percentage  of a  fund's  net  assets  invested  in  "cash
equivalents"--highly liquid, short-term, interest-bearing securities.

CONVERSION PREMIUM.  The average percentage by which the weighted average market
price of the convertible  securities held by a fund exceeds the weighted average
market price of their  underlying  common  stocks.  For  example,  if a stock is
trading at $25 per share and a bond  convertible  into the stock is trading at a
price equivalent to $30 per share of stock, the conversion  premium is 20% ($5 /
$25 = 20%).

DISTRIBUTION BY CREDIT QUALITY.  This breakdown of a fund's securities by credit
rating can help in gauging the risk that  returns  could be affected by defaults
or other credit problems.

DISTRIBUTION BY MATURITY.  An indicator of interest-rate  risk. In general,  the
higher the  concentration  of  longer-maturity  issues,  the more a fund's share
price will fluctuate in response to changes in interest rates.

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  net  assets  represented  by
securities of companies based outside the United States.

NUMBER OF SECURITIES. An indicator of diversification.  The more separate issues
a fund holds,  the less  susceptible it is to a price decline  stemming from the
problems of a particular security.

R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the overall market (or its benchmark  index). If a fund's total
return  were  precisely  synchronized  with the  overall  market's  return,  its
R-squared  would  be 1.00.  If a  fund's  returns  bore no  relationship  to the
market's returns, its R-squared would be 0.

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

TEN LARGEST  HOLDINGS.  The percentage of net assets that a fund has invested in
its ten largest holdings.  As this percentage rises, a fund'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.  Funds
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 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.

FINANCIAL STATEMENTS
NOVEMBER 30, 1999

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 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 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 amount shareholders invested in the
fund,  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  fund's  investment  results  and  distributions  to
shareholders on a per-share  basis. It also presents the fund'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 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.

NOTES TO FINANCIAL STATEMENTS
Vanguard Convertible  Securities Fund 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 fund  consistently  follows such
policies in preparing its financial statements.
     1. SECURITY  VALUATION:  Equity  securities 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.  Prices are taken from the primary  market in which each security
trades.  Bonds 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.
Temporary cash investments are valued at cost, which approximates  market value.
Securities for which market  quotations are not readily  available are valued by
methods deemed by the Board of Trustees to represent fair value.
     2.  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.
     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.  DISTRIBUTIONS:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend  date.  Distributions  are  determined on a tax basis and may differ
from net investment  income and realized  capital gains for financial  reporting
purposes.
     5. OTHER:  Dividend  income is recorded on the ex-dividend  date.  Security
transactions  are accounted for on the date the  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.  Discounts  on  debt
securities  purchased  are  accreted  to  interest  income over the lives of the
respective securities.

B. Oaktree Capital Management, 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 relative
to the Credit Suisse First Boston  Convertible  Securities  Index.  For the year
ended November 30, 1999, the advisory fee  represented an effective  annual rate
of 0.41% of the fund's average net assets before a decrease of $369,000  (0.22%)
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 November 30, 1999, the fund had contributed  capital of $35,000 to
Vanguard (included in Other Assets), representing 0.02% of the fund's net assets
and 0.04% of  Vanguard's  capitalization.  The fund's  Trustees and officers are
also Directors and officers of Vanguard.

                                       19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

D. During the year ended November 30, 1999, the fund purchased  $264,904,000  of
investment securities and sold $311,134,000 of investment securities, other than
temporary  cash  investments.  The fund  used a  capital  loss  carryforward  of
$1,465,000  to offset  taxable  capital  gains  realized  during  the year ended
November 30, 1999,  reducing the amount of capital gains that would otherwise be
available to distribute to shareholders.

E. At November 30, 1999, net unrealized  appreciation  of investment  securities
for  financial  reporting  and  federal  income tax  purposes  was  $13,285,000,
consisting of unrealized  gains of $16,275,000  on securities  that had risen in
value since their  purchase and  $2,990,000 in  unrealized  losses on securities
that had fallen in value since their purchase.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of
Vanguard Convertible Securities Fund

In our  opinion,  the  accompanying  statements  of net assets and of assets and
liabilities,  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  Convertible  Securities Fund (the "Fund") at
November 30, 1999, 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 Fund'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 November  30, 1999 by
correspondence  with the custodian,  provide a reasonable  basis for the opinion
expressed above.

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 part owner
of the fund.  Your fund  Trustees  also serve on the Board of  Directors  of The
Vanguard  Group,  which is owned by the  funds  and  exists  solely  to  provide
services to them on an at-cost basis.
     Seven of Vanguard's nine 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.  They 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 the funds.
     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  Trustees/Directors;   and  electing
Vanguard officers.
     The list below provides a brief description of each Trustee's  professional
affiliations.  Noted in  parentheses is the year in which the Trustee joined the
Vanguard Board.
