INVESTMENT Vanguard Convertible Securities Fund, Inc. (the "Fund") is
OBJECTIVE AND an open-end diversified investment company that seeks to
POLICIES provide current income and long-term growth of capital.
The Fund invests primarily in corporate bonds and pre-
ferred stocks that are convertible into shares of common
stock. Although the Fund is designed principally for equi-
ty-oriented investors, you should be aware that a majority
of the Fund's assets may be invested in convertible secu-
rities rated Ba or B by Moody's Investors Service or BB or
B by Standard & Poor's Corporation. Corporate bonds with
such ratings are commonly referred to as "junk bonds" and
are considered speculative by the major ratings agencies.
There is no assurance that the Fund will achieve its
stated objectives. Shares of the Fund are neither insured
nor guaranteed by any agency of the U.S. Government, in-
cluding the FDIC.

YIELD AND TOTAL From time to time the Fund may advertise its yield and to-
RETURN tal return. Both yield and total return figures are based
on historical earnings and are not intended to indicate
future performance. The "total return" of the Fund refers
to the average annual compounded rates of return over one-
, five- and ten-year periods or the life of the Fund (as
stated in the advertisement) that would equate an initial
amount invested at the beginning of a stated period to the
ending redeemable value of the investment, assuming the
reinvestment of all dividend and capital gains distribu-
tions.
In accordance with industry guidelines set forth by the
U.S. Securities and Exchange Commission, the "30-day
yield" of the Fund is calculated by dividing the net in-
vestment income per share earned during a 30-day period by
the net asset value per share on the last day of the peri-
od. Net investment income includes interest and dividend
income earned on the Fund's securities; it is net of all
expenses and all recurring and nonrecurring charges that
have been applied to all shareholder accounts. The yield
calculation assumes that the net investment income earned
over 30 days is compounded monthly for six months and then
annualized. Methods used to calculate advertised yields
are standardized for all stock and bond mutual funds. How-
ever, these methods differ from the accounting methods
used by the Fund to maintain its books and records, and so
the advertised 30-day yield may not fully reflect the in-
come paid to an investor's account or the yield reported
in the Fund's reports to shareholders.

AND LONG-TERM
GROWTH The investment objective of the Fund is fundamental and so
cannot be changed without the approval of a majority of
the Fund's shareholders.
- -------------------------------------------------------------------------------
INVESTMENT Under normal circumstances, at least 80% of the Fund's as-
POLICIES sets will be invested in convertible securities. Convert-
ible securities include corporate bonds and preferred
stocks which are convertible into common stock, as well as
debt instruments with warrants or common stock attached.
See "Implementation of Policies" for a description of con-
vertible securities.
THE FUND INVESTS The remaining 20% of the Fund's assets may be invested in
IN CONVERTIBLE non-convertible corporate or U.S. Government fixed-income
SECURITIES securities, common stocks, and selected money market in-
struments. Within this 20% limit, the Fund is authorized
to write covered call options on its investments, although
it does not presently intend to do so. The Fund may also
invest more than 20% of its assets in money market instru-
ments when the Fund's investment adviser determines that a
temporary defensive position is warranted.
In seeking to provide both current income and long-term
capital appreciation, the adviser will emphasize the secu-
rities of companies with above-average growth potential
whose convertible securities offer attractive yields. In
general, each security selected for the Fund will, in the
opinion of the adviser, be priced at a reasonable premium
relative to the price at which it can be converted into
common stock.
The Fund will predominantly invest in convertible obliga-
tions which have been assigned a rating of B or better by
Moody's Investors Service, Inc. ("Moody's") or Standard &
Poor's Corporation ("Standard & Poor's"). The Fund may
also invest in non-rated securities that, in the opinion
of the Fund's adviser, are equivalent in quality to a B
rating or better.
While the Fund will invest predominately in securities of
U.S.-based companies, up to 20% of the Fund's assets may
be invested in dollar-denominated securities issued by
foreign companies. See "Implementation of Policies" for a
description of other investment practices of the Fund.
The Fund is responsible for voting the shares of all secu-
rities it holds.
These policies are not fundamental and so may be changed
by the Board of Directors without shareholder approval.
However, before making any important change in its poli-
cies, the Fund will give shareholders 30-days notice, in
writing.

INVESTMENT RISKS Convertible securities are hybrid securities, combining
the investment characteristics of both bonds and common
THE FUND IS stocks. Like a bond (or preferred stock), a convertible
SUBJECT TO STOCK security pays a fixed interest rate (dividend), but may be
AND BOND MARKET converted into common stock at a specific price or conver-
RISK sion rate.
When the convertible's conversion price is significantly
above the price of the issuer's common stock, a convert-
ible security takes on the risk characteristics of a bond.
At such times, the price of a convertible security will
vary inversely with changes in the level of interest
rates. In other words, when interest rates rise, convert-
ible securities prices will generally fall; conversely,
when interest rates fall, convertible securities prices
will generally rise. This interest rate risk is in part
offset by the income paid by the convertible securities.
In contrast, when the conversion price of a convertible
security and the common stock price are close to one an-
other, a convertible security will behave like a common
stock. In such cases, the prices of convertible securities
may exhibit the short-term price volatility characteristic
of common stocks.
For these reasons, investors in the Fund must be willing
to accept the market risks of both bonds and stocks. How-
ever, because convertible securities have characteristics
of both stocks and bonds, they tend to be less sensitive
to interest rate changes than bonds of comparable maturity
and quality, and less sensitive to stock market changes
than fully invested common stock portfolios. Because of
these factors and the hybrid nature of convertibles, in-
vestors should recognize that convertible securities are
likely to perform quite differently than broadly-based
measures of the stock and bond markets.
INTERNATIONAL The Fund may invest as much as 20% of its assets in for-
STOCKS EXPOSE eign securities. These securities can be traded in either
INVESTORS TO U.S. or foreign markets. Because of its foreign invest-
COUNTRY RISKS ments, the Fund is subject to country risk and currency
AND CURRENCY risk. Country risk is the possibility that political
RISKS events (such as a war), financial problems (such as gov-
ernment default), or natural disasters (such as an earth-
quake) will weaken a country's economy and cause invest-
ments in that country to lose money. Currency risk is the
possibility that a "stronger" U.S. dollar will reduce re-
turns for Americans investing overseas. Generally, when
the dollar rises in value against a foreign currency, your
investment in that country loses value because its cur-
rency is worth fewer U.S. dollars.
CREDIT QUALITY The market for convertible securities includes a larger
MAY BE LOW proportion of small-to-medium size companies than the
broad stock market (as measured by such indices as the
Standard & Poor's 500 Composite Stock Price Index). Compa-
nies which issue convertible securities are often lower in
credit quality. Moreover, the credit rating of a company's
convertible issue is generally lower than the rating of
the company's conventional debt issues since the convert-
ible is normally a "junior" security. The average credit
quality of the Fund is expected to be on a par with the
universe of convertible securities as a whole, and the
Fund may invest up to 100% of its assets in securities
rated Ba (BB) or less. Securities with such ratings
5
<PAGE>
are considered speculative, and thus pose a greater risk
of default than investment grade securities. The following
are excerpts from the Moody's and Standard & Poor's defi-
nitions for speculative debt obligations:
Moody's: Ba-rated bonds have "speculative elements," their
future "cannot be considered assured," and protection of
principal and interest is "moderate" and "not well safe-
guarded." B-rated bonds "lack characteristics of a desir-
able investment" and the assurance of interest or princi-
pal payments "may be small."
Caa-rated bonds are "of poor standing" and "may be in de-
fault" or may have "elements of danger with respect to
principal or interest."
Standard & Poor's: BB-rated bonds have "less near-term
vulnerability to default" than B- or CCC-rated securities
but face "major ongoing uncertainties . . . which may lead
to inadequate capacity" to pay interest or principal. B-
rated bonds have a "greater vulnerability to default" than
BB-rated bonds and the ability to pay interest or princi-
pal will likely be impaired by adverse business condi-
tions. CCC-rated bonds have a "currently identifiable vul-
nerability to default" and, without favorable business
conditions, will be unable to repay interest and princi-
pal.
Securities rated Ba or lower are considered to be "high-
risk" securities and the credit quality of such securities
can change suddenly and unexpectedly, and even recently-
issued credit ratings may not fully reflect the actual
risks of a particular security. For these reasons, it is
the Fund's policy not to rely primarily on ratings issued
by established credit rating agencies, but to utilize such
ratings in conjunction with the Portfolio adviser's own
independent and ongoing review of the companies repre-
sented in the Fund.
In the past, the high yields from a portfolio of low-grade
securities have more than compensated for the higher de-
fault rates on such securities. However, there can be no
assurance that diversification will protect the Fund from
widespread defaults brought about by a sustained economic
downturn, or that yields will continue to offset default
rates on high-yield securities in the future.
- -------------------------------------------------------------------------------
WHO SHOULD The Fund is intended for investors who are seeking a
INVEST higher level of income than is normally available from
common stocks, as well as potential long-term capital ap-
INVESTORS preciation. Since the Fund may own non-investment grade
SEEKING CURRENT securities of medium-to-small-sized companies, greater-
INCOME AND LONG- than-average investment risk may be involved. Investors
TERM CAPITAL should be able to tolerate sharp, sometimes sudden fluctu-
GROWTH ations in the value of their investment in pursuit of
higher investment returns in the long run.
Although convertible securities exhibit characteristics of
both stocks and bonds, the Fund does not represent a com-
plete investment program. Most investors should maintain
diversified holdings of securities with different risk
characteristics--including common stocks, bonds and money
market instruments. The Fund is intended to be a long-term
investment vehicle and is not designed to provide invest-
ors with a means of speculating on short-term market move-
ments.

<PAGE>
Investors who engage in excessive account activity gener-
ate additional costs which are borne by all of the Fund's
shareholders. In order to minimize such costs, the Fund
has adopted the following policies. The Fund reserves the
right to reject any purchase request (including exchange
purchases from other Vanguard portfolios) that is reasona-
bly deemed to be disruptive to efficient portfolio manage-
ment, either because of the timing of the investment or
previous excessive trading by the investor. Additionally,
the Fund has adopted exchange privilege limitations as de-
scribed in the section "Exchange Privilege Limitations."
Finally, the Fund reserves the right to suspend the offer-
ing of its shares.
- -------------------------------------------------------------------------------
IMPLEMENTATION The Fund uses a number of investment vehicles to achieve
OF POLICIES its objective.
THE FUND INVESTS The Fund invests primarily in convertible securities. Con-
IN CONVERTIBLE vertible securities include corporate bonds, debentures,
SECURITIES notes and preferred stocks which may be converted into the
common stock of the issuer at the holder's option. Con-
vertible securities obligate the issuing company to pay a
stated annual rate of interest (or a stated dividend in
the case of convertible preferred stock) and to return the
principal amount after a specified period. Convertible se-
curities generally offer income yields that are higher
than the dividend yield, if any, of the underlying common
stock, but lower than the yield of non-convertible debt
securities issued by the corporation or corporations of
similar investment quality. This fixed-income feature of
convertible securities is expected to enable the Fund to
achieve its current income objective. Convertible securi-
ties are usually priced at a premium to their conversion
value--i.e., the value of the common stock received if the
holder were to exchange the convertible security.
The holder of the convertible security may choose at any
time to exchange the convertible security for a specified
number of shares of the common stock of the corporation,
or occasionally a subsidiary company, at a specified
price, as defined by the corporation when the security is
issued. Accordingly, the value of the convertible obliga-
tion may generally be expected to increase (decrease) as
the price of the associated common stock increases (de-
creases). Also, the market value of convertible securities
tends to be influenced by the level of interest rates and
tends to decline as interest rates increase and, converse-
ly, to increase as interest rates decline.
Convertible securities rank senior to common stocks in an
issuer's capital structure, but are generally junior to
non-convertible debt securities. As convertible securities
are considered junior to any non-convertible debt securi-
ties issued by the corporation, convertible securities are
typically rated by established credit rating services at
one level below the corporation's non-convertible debt.
THE FUND MAY Although it normally seeks to remain fully invested in
INVEST IN SHORT- convertible securities, the Fund may invest in certain
TERM FIXED short-term fixed income securities. Such securities may be
INCOME used to invest uncommitted cash balances, to maintain li-
SECURITIES quidity to meet shareholder redemptions, or to take a tem-
porary defensive position. These securities include: obli-
gations of the United States Government and its agencies
or
7
<PAGE>
instrumentalities, commercial paper, bank certificates of
deposit, and bankers' acceptances, and repurchase agree-
ments collateralized by these securities.
THE FUND MAY The Fund may lend its investment securities on a short-
LEND ITS term or a long-term basis to qualified institutional in-
SECURITIES vestors for the purpose of realizing additional income.
Loans of securities by the Fund will be collateralized by
cash, letters of credit, or securities issued or guaran-
teed by the U.S. Government or its agencies. The collat-
eral will equal at least 100% of the current market value
of the loaned securities.
THE FUND MAY The Fund may borrow money, subject to the limits set forth
BORROW MONEY below, for temporary or emergency purposes, including the
meeting of redemption requests which might otherwise re-
quire the untimely disposition of securities.
PORTFOLIO The Fund retains the right to sell securities irrespective
TURNOVER IS NOT of how long they have been held. However, depending on
EXPECTED TO market conditions and other factors, it is expected that
EXCEED 100% the portfolio turnover rate for the Fund will not normally
exceed 100%. A turnover rate of 100% would occur, for ex-
ample, if all of the Fund's securities were replaced
within one year. Because of the Fund's change in invest-
ment adviser in November 1996, the turnover rate for 1997
exceeded 100%.
DERIVATIVE Derivatives are instruments whose values are linked to or
INVESTING derived from an underlying security or index. The most
common and conventional types of derivative securities are
futures and options.
THE FUND MAY The Fund may invest in futures contracts and options, but
INVEST IN only to a limited extent. Specifically, the Fund may enter
DERIVATIVE into futures contracts provided that not more than 5% of
SECURITIES its assets are required as a futures contract deposit; in
addition, the Fund may enter into futures contracts and
options transactions only to the extent that obligations
under such contracts or transactions represent not more
than 20% of the Fund's assets.
Futures contracts and options may be used for several com-
mon fund management strategies: to maintain cash reserves
while simulating full investment, to facilitate trading,
to reduce transaction costs, or to seek higher investment
returns when a specific futures contract is priced more
attractively than other futures contracts or the under-
lying security or index.
The Fund may use futures contracts for bona fide "hedging"
purposes. In executing a hedge, a manager sells, for exam-
ple, stock index futures to protect against a decline in
the stock market. As such, if the market drops, the value
of the futures position will rise, thereby offsetting the
decline in value of the Fund's stock holdings.
FUTURES The primary risks associated with the use of futures con-
CONTRACTS AND tracts and options are: (i) imperfect correlation between

CERTAIN RISKS and the prices of futures contracts and options; and (ii)
possible lack of a liquid secondary market for a futures
contract and the resulting inability to close a futures
position prior to its maturity date. The risk of imperfect
correlation will be minimized by investing in those con-
tracts whose price fluctuations are
8
<PAGE>
expected to resemble those of the Fund's underlying secu-
rities. The risk that the Fund will be unable to close out
a futures position will be minimized by entering into such
transactions on a national exchange with an active and
liquid secondary market.
The risk of loss in trading futures contracts in some
strategies can be substantial, due both to the low margin
deposits required and the extremely high degree of lever-
age involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in
immediate and substantial loss (or gain) to the investor.
When investing in futures contracts, the Fund will segre-
gate cash or other liquid portfolio securities in the
amount of the underlying obligation.
- -------------------------------------------------------------------------------
INVESTMENT The Fund has adopted limitations on some of its investment
LIMITATIONS policies. Some of these limitations are that the Fund will
not:
THE FUND HAS (a) with respect to 75% of the value of its total assets,
ADOPTED CERTAIN purchase the securities of any issuer (except
FUNDAMENTAL obligations of the United States Government and its
LIMITATIONS instrumentalities) if as a result the Fund would hold
more than 10% of the outstanding voting securities of
the issuer, or more than 5% of the value of the Fund's
total assets would be invested in the securities of
such issuer;
(b) invest more than 5% of its assets in the securities of
companies that have a continuous operating history of
less than three years;
(c) invest more than 25% of its assets in any one
industry;
(d) borrow money, except that the Fund may borrow from
banks (or through reverse repurchase agreements), for
temporary or emergency (not leveraging) purposes,
including the meeting of redemption requests which
might otherwise require the untimely disposition of
securities, in an amount not exceeding 10% of the
value of the Fund's net assets (including the amount
borrowed) at the time the borrowing is made. Whenever
borrowings exceed 5% of the value of the Fund's net
assets, the Fund will not make any additional
investments;
(e) pledge, mortgage or hypothecate any of its assets to
an extent greater than 5% of its total assets.
A complete list of the Fund's investment limitations can
be found in the Statement of Additional Information. These
limitations are fundamental and may be changed only by ap-
proval of a majority of the Fund's shareholders.
- -------------------------------------------------------------------------------
MANAGEMENT OF The Fund is a member of The Vanguard Group of Investment
THE FUND Companies, a family of more than 30 funds, with more than
95 portfolios and total assets in excess of $340 billion.
VANGUARD Through their jointly-owned subsidiary, The Vanguard
ADMINISTERS AND Group, Inc. ("Vanguard"), the Fund and the other funds in
DISTRIBUTES THE the Group obtain at cost virtually all of their corporate
FUND management, administrative, shareholder accounting and
distribution services. Vanguard also provides investment
advisory services on an at-cost basis to certain Vanguard
funds. As a result of Vanguard's unique
9
<PAGE>
corporate structure, the Vanguard funds have costs sub-
stantially lower than those of most competing mutual
funds. In 1997, the average expense ratio (annual costs
including advisory fees divided by total net assets) for
the Vanguard funds amounted to approximately 0.28% com-
pared to an average of 1.24% for other mutual funds (data
provided by Lipper Analytical Services).
The Officers of the Fund manage its day-to-day operations
and are responsible to the Fund's Board of Directors. The
Directors set broad policies for the Fund and choose its
Officers. A list of the Directors and Officers of the Fund
and a statement of their present positions and principal
occupations during the past five years can be found in the
Statement of Additional Information.
Vanguard employs a supporting staff of management and ad-
ministrative personnel needed to provide the requisite
services to the funds and also furnishes the funds with
necessary office space, furnishings and equipment. Each
fund pays its share of Vanguard's total expenses, which
are allocated among the funds under methods approved by
the Board of Directors (Trustees) of each fund. In addi-
tion, each fund bears its own direct expenses, such as le-
gal, auditing and custodian fees.
Vanguard also provides distribution and marketing service
to the Vanguard funds. The funds are available on a no-
load basis (i.e., there are no sales commissions or 12b-1
fees). However, each fund bears its share of Vanguard's
distribution costs.
- -------------------------------------------------------------------------------
INVESTMENT The Fund employs Oaktree Capital Management, LLC
ADVISER ("Oaktree"), 550 South Hope Street, 22nd Floor, Los Ange-
les, California, 90071, under an investment advisory
agreement dated November 1, 1996, to manage the investment
and reinvestment of the assets of the Fund and to continu-
ously review, supervise and administer the Fund's invest-
ment program. Oaktree discharges its responsibilities sub-
ject to the control of the Officers and Directors of the
Fund.
OAKTREE CAPITAL Oaktree specializes in selected niche investment markets.
MANAGEMENT, LLC The founders of Oaktree formed the company in April of
MANAGES THE 1995 after having managed funds in the convertible securi-
FUND'S ties, distressed debt, and high yield bond areas of Trust
INVESTMENTS Company of the West since 1985.
Larry W. Keele, Principal and one of the five founders of
Oaktree, serves as Portfolio Manager of the Fund. Mr.
Keele is supported by research and other investment serv-
ices provided by the professional staff of Oaktree. As of
November 30, 1997, Oaktree managed approximately $9.7 bil-
lion.
10
<PAGE>
The Fund pays Oaktree an advisory fee at the end of each
fiscal quarter, calculated by applying a quarterly rate,
based on the following annual percentage rates, to the
Fund's average month-end net assets for the quarter (the
"Basic Fee"):
<TABLE>
<CAPTION>
NET ASSETS RATE
------------------ ------
<S> <C>
First $100 million 0.425%
Next $100 million 0.400%
Next $100 million 0.375%
Next $100 million 0.350%
Over $400 million 0.325%
</TABLE>
The advisory fee may be increased or decreased by an
incentive/penalty fee based on the Fund's total return
performance as compared to that of the First Boston Con-
vertible Securities Index. Under the fee schedule, the Ba-
sic Fee may be increased or decreased by as much as 50%.
The incentive/penalty fee structure will not be in full
operation until the quarter ending November 30, 1999. Un-
til then, the incentive/penalty fee will be calculated us-
ing certain transition rules. The incentive/penalty fee
schedule and calculation process for the Fund's first
three years are described in the Fund's Statement of Addi-
tional Information, which can be obtained by writing to or
calling Vanguard.
During the fiscal year ended November 30, 1997, the total
advisory fees paid by the Fund to Oaktree represented an
effective annual base rate of 0.42% of the Fund's average
net assets before a decrease of 0.05% based on perfor-
mance.
The investment advisory agreement authorizes Oaktree to
select the brokers or dealers that will execute the pur-
chases and sales of portfolio securities for the Fund and
directs Oaktree to use its best efforts to obtain the best
available price and most favorable execution with respect
to all transactions for the Fund. The full range and qual-
ity of brokerage services are considered in making
these determinations.
The Fund has authorized Oaktree to pay higher commissions
in recognition of brokerage services felt necessary for
the achievement of better execution, provided the adviser
believes this to be in the best interest of the Fund. If
more than one broker can obtain the best available price
and favorable execution of a transaction, then Oaktree is
authorized to choose a broker who, in addition to execut-
ing the transaction, will provide research services to
Oaktree or the Fund. However, Oaktree will not pay higher
commissions specifically for the purpose of obtaining re-
search services. The Fund may direct Oaktree to use a par-
ticular broker for certain transactions in exchange for
commission rebates or research services provided to the
Fund.
The Fund's Board of Directors may, without the approval of
shareholders, provide for: (a) the employment of a new in-
vestment adviser pursuant to the terms of a new advisory
agreement, either as a replacement for an existing adviser
or as an additional adviser; (b) a change in the terms of
an advisory agreement; and
11
<PAGE>
(c) the continued employment of an existing adviser on the
same advisory contract terms where a contract has been as-
signed because of a change in control of the adviser. Any
such change will only be made upon not less than 30 days'
prior written notice to shareholders of the Fund, which
shall include substantially the information concerning the
adviser that would have normally been included in a proxy
statement.

PERFORMANCE The table in this section provides investment results for
RECORD the Fund for several periods throughout the Fund's life-
time. The results shown represent the Fund's "total re-
turn" investment performance, which assumes the reinvest-
ment of all capital gains and income dividends for the in-
dicated periods. Also included is comparative information
with respect to the unmanaged Standard & Poor's 500 Com-
posite Stock Price Index, a widely-used barometer of stock
market activity, and the Lehman Aggregate Bond Index, a
measure of the investment performance of the bond market.
The table does not make any allowance for federal, state
or local income taxes, which shareholders must pay on a
current basis.
The results should not be considered a representation of
the total return from an investment made in the Fund to-
day. This information is provided to help investors better
understand the Fund and may not provide a basis for com-
parison with other investments or mutual funds which use a
different method to calculate performance.

DIVIDENDS, The Fund expects to pay quarterly dividends from net in-
CAPITAL GAINS vestment income. Net capital gains distributions, if any,
AND TAXES will be made annually.
THE FUND WILL Dividend and capital gains distributions may be automati-
PAY QUARTERLY cally reinvested or received in cash. See "Choosing a Dis-
DIVIDENDS tribution Option" for a description of these distribution
methods.
In addition, in order to satisfy certain distribution re-
quirements of the Tax Reform Act of 1986, the Fund may de-
clare special year-end dividend and capital gains distri-
butions during December. Such distributions, if received
by shareholders by January 31, are deemed to have been
paid by the Fund and received by shareholders on December
31 of the prior year.
12
<PAGE>
The Fund intends to continue to qualify for taxation as a
"regulated investment company" under the Internal Revenue
Code so that it will not be subject to federal income tax
to the extent its income is distributed to shareholders.
Dividends paid by the Fund from net investment income,
whether received in cash or reinvested in additional
shares, will be taxable to shareholders as ordinary in-
come. For corporate investors, a portion of dividends from
net investment income will qualify for the intercorporate
dividends-received deduction. However, the portion of the
dividends so qualified depends on the aggregate taxable
qualifying dividend income received by the Fund from do-
mestic (U.S.) sources.
Distributions paid by the Fund from net long-term capital
gains, whether received in cash or reinvested in addi-
tional shares, are taxable as long-term capital gains, re-
gardless of the length of time you have owned shares in
the Fund. Long-term capital gains may be taxed at differ-
ent rates depending on how long the Fund held the securi-
ties. Capital gains distributions are made when the Fund
realizes net capital gains on sales of portfolio securi-
ties during the year. The Fund does not seek to realize
any particular amount of capital gains during a year;
rather, realized gains are a by-product of portfolio man-
agement activities. Consequently, capital gains distribu-
tions may be expected to vary considerably from year to
year; there will be no capital gains distributions in
years when the Fund realizes net capital losses.
Note that if you accept capital gains distributions in
cash, instead of reinvesting them in additional shares,
you are in effect reducing the capital at work for you in
the Fund. Also, keep in mind that if you purchase shares
in the Fund shortly before the record date for a dividend
or capital gains distribution, a portion of your invest-
ment will be returned to you as a taxable distribution,
regardless of whether you are reinvesting your distribu-
tions or receiving them in cash.
The Fund will notify you annually as to the tax status of
dividend and capital gains distributions paid by the Fund.
A CAPITAL GAIN A sale of shares of the Fund is a taxable event and may
OR LOSS MAY BE result in a capital gain or loss. A capital gain or loss
REALIZED UPON may be realized from an ordinary redemption of shares or
EXCHANGE OR an exchange of shares between two mutual funds (or two
REDEMPTION portfolios of a mutual fund).
Dividend distributions, capital gains distributions, and
capital gains or losses from redemptions and exchanges may
be subject to state and local taxes.
The Fund is required to withhold 31% of taxable dividends,
capital gains distributions, and redemptions paid to
shareholders who have not complied with IRS taxpayer iden-
tification regulations. You may avoid this withholding re-
quirement by certifying on your Account Registration Form
your proper Social Security or taxpayer identification
number and by certifying that you are not subject to
backup withholding.
The Fund has obtained a Certificate of Authority to do
business as a foreign corporation in Pennsylvania and does
business and maintains an office in that state.

<PAGE>
In the opinion of counsel, the shares of the Fund will be
exempt from Pennsylvania personal property taxes.
The tax discussion set forth on page 13 is included for
general information only. Prospective investors should
consult their own tax advisers concerning the tax conse-
quences of an investment in the Fund. The Fund is managed
without regard to tax ramifications.
- -------------------------------------------------------------------------------
THE SHARE PRICE The Fund's share price, or "net asset value" per share, is
OF THE FUND calculated by dividing the total assets of the Fund, less
all liabilities, by the total number of shares outstand-
ing. The net asset value is determined as of the close of
trading on the New York Stock Exchange (generally 4:00
p.m. Eastern time) on each day the exchange is open for
trading.
Portfolio securities for which market quotations are read-
ily available (includes those securities listed on na-
tional securities exchanges, as well as those quoted on
the NASDAQ Stock Market) will be valued at the last quoted
sales price on the day the valuation is made. Such securi-
ties which are not traded on the valuation date are valued
at the mean of the bid and ask prices. Price information
on exchange-listed securities is taken from the exchange
where the security is primarily traded. Any foreign secu-
rities are valued at the latest quoted sales price avail-
able before the time when assets are valued. Securities
may be valued on the basis of prices provided by a pricing
service when such prices are believed to reflect the fair
market value of such securities.
Short-term instruments (those with remaining maturities of
60 days or less) may be valued at cost, plus or minus any
amortized discount or premium, which approximates market
value.
Bonds and other fixed income securities may be valued on
the basis of prices provided by a pricing service when
such prices are believed to reflect the fair market value
of such securities. The prices provided by a pricing serv-
ice may be determined without regard to bid or last sale
prices of each security, but take into account institu-
tional-size transactions in similar groups of securities
as well as any developments related to specific securi-
ties.
Other assets and securities for which no quotations are
readily available or which are restricted as to sale (or
resale) are valued by such methods as the Board of Direc-
tors deems in good faith to reflect fair value.
The share price for the Fund can be found daily in the mu-
tual fund listings of most major newspapers under the
heading of Vanguard Funds.
- -------------------------------------------------------------------------------

CHOOSING A You must select one of four distribution options:
DISTRIBUTION
OPTION 1. AUTOMATIC REINVESTMENT OPTION--Both dividend and capi-
tal gains distributions will be reinvested in addi-
tional Fund shares. This option will be selected for
you automatically unless you specify one of the other
options.
2. CASH DIVIDEND OPTION--Your dividends will be paid in
cash and your capital gains will be reinvested in addi-
tional Fund shares.
3. CASH CAPITAL GAIN OPTION--Your capital gains distribu-
tions will be paid in cash and your dividends will be
reinvested in additional Fund shares.
4. ALL CASH OPTION--Both dividend and capital gains dis-
tributions will be paid in cash.
You may change your option by calling our Client Services
Department (1-800-662-2739).
If a shareholder has chosen to receive dividend and/or
capital gains distributions in cash, and the postal or
other delivery service is unable to deliver checks to the
shareholder's address of record, we will change the dis-
tribution option so that all dividends and other distribu-
tions are automatically reinvested in additional shares.
We will not pay interest on uncashed distribution checks.
In addition, an option to invest your cash dividend and/or
capital gains distributions in another Vanguard Fund ac-
count is available. Please call our Client Services De-
partment (1-800-662-2739) for information. You may also
elect Vanguard Dividend Express which allows you to trans-
fer your cash dividend and/or capital gains distributions
automatically to your bank account. Please see "Other Van-
guard Services" for more information.
- -------------------------------------------------------------------------------
TAX CAUTION Under Federal tax laws, the Fund is required to distribute
net capital gains and dividend income to Fund sharehold-
INVESTORS SHOULD ers. These distributions are made to all shareholders who
ASK ABOUT THE own Fund shares as of the distribution's record date, re-
TIMING OF gardless of how long the shares have been owned. Purchas-
CAPITAL GAINS ing shares just prior to the record date could have a sig-
AND DIVIDEND nificant impact on your tax liability for the year. For
DISTRIBUTIONS example, if you purchase shares immediately prior to the
BEFORE INVESTING record date of a sizable capital gain or income dividend
distribution, you will be assessed taxes on the amount of
the capital gain and/or dividend distribution later paid
even though you owned the Fund shares for just a short pe-
riod of time. (Taxes are due on the distributions even if
the dividend or gain is reinvested in additional Fund
shares.) While the total value of your investment will be
the same after the distribution--the amount of the distri-
bution will offset the drop in the net asset value of the
shares--you should be aware of the tax implications the
timing of your purchase may have.
18
<PAGE>
Prospective investors should, therefore, inquire about po-
tential distributions before investing. The Fund's annual
capital gains distribution normally occurs in December,
while income dividends are generally paid quarterly in
March, June, September and December. In addition, the Fund
may occasionally be required to make supplemental dividend
or capital gains distributions at some other time during
the year. For additional information on distributions and
taxes, see the section titled "Dividends, Capital Gains,
and Taxes."

DELIVERY OF Redemption requests received by telephone prior to the
REDEMPTION close of regular trading on the New York Stock Exchange
PROCEEDS are processed on the day of receipt and the redemption
proceeds are normally sent on the following business day.

lowing receipt and the proceeds are normally sent on the
second business day following receipt.
Redemption proceeds must be sent to you within seven days
of receipt of your request in Good Order except as de-
scribed above in "Important Redemption Information."
If you experience difficulty in making a telephone redemp-
tion during periods of drastic economic or market changes,
your redemption request may be made by regular or express
mail. It will be implemented at the net asset value next
determined after your request has been received by Van-
guard in Good Order. The Fund reserves the right to revise

rimental to the best interests of the Fund's remaining

AVERAGE COST guard will send you an Average Cost Statement which pro-
STATEMENT vides you with the tax basis of the shares you redeemed.
Please see "Statements and Reports" for additional infor-
mation.
-----------------------------------------------------------
LOW BALANCE FEE Due to the relatively high cost of maintaining smaller ac-
AND MINIMUM counts, the Fund will automatically deduct a $10 annual
ACCOUNT BALANCE fee in either June or December from non-retirement ac-
REQUIREMENT counts with balances falling below $2,500 ($500 for Uni-
form Gifts/Transfers to Minors Act accounts). The fee gen-
erally will be waived for investors whose aggregate Van-
guard assets exceed $50,000.
In addition, the Fund reserves the right to liquidate any
non-retirement account that is below the minimum initial
investment amount of $3,000. If at any time the total in-
vestment does not have a value of at least $3,000, you may
be notified that your account is below the Fund's minimum
account balance requirement. You
21
<PAGE>
would then be allowed 60 days to make an additional in-
vestment before the account is liquidated. Proceeds would
be promptly paid to the registered shareholder.
Vanguard will not liquidate your account if it has fallen
below $3,000 solely as a result of declining markets
(i.e., a decline in a Fund's net asset value).

IMPORTANT Before you make an exchange, you should consider the fol-
EXCHANGE lowing:
INFORMATION
. Please read the Fund's prospectus before making an ex-
change. For a copy and for answers to any questions you
may have, call our Investor Information Department (1-
800-662-7447).
. An exchange is treated as a redemption and a purchase.
Therefore, you could realize a taxable gain or loss on
the transaction.
. Exchanges by telephone are accepted only if the regis-
trations and the taxpayer identification numbers of the
two accounts are identical.
. To exchange into an account with a different registra-
tion (including a different name, address, or taxpayer
identification number), you must provide Vanguard with
written instructions that include the guaranteed signa-
tures of all current account owners.
. The shares to be exchanged must be on deposit and not
held in certificate form.
. New accounts are not currently accepted in
Vanguard/Windsor Fund.
. The redemption price of shares redeemed by exchange is
the net asset value next determined after Vanguard has
received the required documentation in Good Order.
. When opening a new account by exchange, you must meet
the minimum investment requirement of the new Fund.
Every effort will be made to maintain the exchange privi-
lege. However, the Fund reserves the right to revise or
terminate its provisions, limit the amount of, or reject
any exchange, as deemed necessary, at any time.
The exchange privilege is only available in states in
which shares of the Fund are registered for sale. The
Fund's shares are currently registered for sale in all 50
states and the Fund intends to maintain such registration.
- -------------------------------------------------------------------------------
EXCHANGE The Fund's exchange privilege is not intended to afford
PRIVILEGE shareholders a way to speculate on short-term movements in
LIMITATIONS the market. Accordingly, in order to prevent excessive use
of the exchange privilege that may potentially disrupt the
management of the Fund and increase transaction costs, the
Fund has established a policy of limiting excessive ex-
change activity.
Exchange activity generally will not be deemed excessive
if limited to two substantive exchange redemptions (at
least 30 days apart) from the Fund during any twelve month
period. "Substantive" means either a dollar amount or a
series of movements between Vanguard funds that Vanguard
determines, in its sole discretion, could have an adverse
impact on the management of the Fund. Notwithstanding
these limitations, the Fund reserves the right to reject
any purchase request (including exchange purchases from
other Vanguard portfolios) that is reasonably deemed to be
disruptive to efficient portfolio management.
- -------------------------------------------------------------------------------

<PAGE>
IMPORTANT The ability to initiate redemptions (except wire or Fund
INFORMATION Express redemptions) and exchanges by telephone is auto-
ABOUT TELEPHONE matically established on your account unless you request
TRANSACTIONS in writing that telephone transactions on your account not
be permitted.
To protect your account from losses resulting from unau-
thorized or fraudulent telephone instructions, Vanguard
adheres to the following security procedures:
1. SECURITY CHECK. To request a transaction by telephone,
the caller must know (i) the name of the Fund; (ii) the
10-digit account number; (iii) the exact name and ad-
dress used in the registration; and (iv) the Social Se-
curity or employer identification number listed on the
account.
2. PAYMENT POLICY. The proceeds of any telephone redemp-
tion made by mail will be made payable to the regis-
tered shareowner and mailed to the address of record,
only.
Neither the Fund nor Vanguard will be responsible for the
authenticity of transaction instructions received by tele-
phone, provided that reasonable security procedures have
been followed. Vanguard believes that the security proce-
dures described above are reasonable, and that if such
procedures are followed, you will bear the risk of any
losses resulting from unauthorized or fraudulent telephone
transactions on your account.

INVESTMENT LIMITATIONS
The following restrictions are fundamental policies and cannot be changed
without approval of the holders of a majority of the outstanding shares of the
Fund or, if less, 67% of the shares represented at a meeting of shareholders
at which the holders of 50% or more of the shares are represented. The Fund
may not under any circumstances:
1. Borrow money, except that the Fund may borrow from banks (or through
reverse repurchase agreements), for temporary or emergency (not leveraging)
purposes, including the meeting of redemption requests which might other-
wise require the untimely disposition of securities, in an amount not ex-
ceeding 10% of the value of the Fund's total assets (including the amount
borrowed) at the time the borrowing is made. Whenever borrowings exceed 5%
of the value of the Fund's total assets, the Fund will not make any addi-
tional investments;
2. With respect to 75% of the value of its total assets, purchase the se-
curities of any issuer (except obligations of the United States government
and its instrumentalities) if as a result the Fund would hold more than 10%
of the outstanding voting securities of the issuer, or more than 5% of the
value of the Fund's total assets would be invested in the securities of
such issuer;
3. Invest for the purpose of exercising control of management of any com-
pany;
4. Invest in securities of other investment companies, except as they may
be acquired as part of a merger, consolidation or acquisition of assets or
otherwise to the extent permitted by Section 12 of the Investment Company
Act of 1940 (the "1940 Act"). The Fund will invest only in investment com-
panies which have investment objectives and investment policies consistent
with those of the Fund;
B-1
<PAGE>
5. Engage in the business of underwriting securities issued by other per-
sons, except to the extent that the Fund may technically be deemed to be an
underwriter under the Securities Act of 1933, as amended, in disposing of
investment securities;
6. Purchase or otherwise acquire any security if, as a result, more than
15% of its net assets would be invested in securities that are illiquid
(including the Fund's investment in The Vanguard Group, Inc.);
7. Invest in commodities or real estate, although the Fund may purchase
and sell securities of companies which deal in real estate, or interests
therein, and the Fund may purchase covered call options as described in the
prospectus;
8. Purchase securities on margin or sell any securities short;
9. Invest more than 5% of the assets of the Fund, at the time of invest-
ment, in the securities of any issuers which have (with predecessors) a
record of less than three years' continuous operation;
10. Purchase or retain any security if (i) one or more officers, direc-
tors or partners of the Fund or its investment adviser individually own or
would own, directly or beneficially, more than 1/2 of 1 per cent of the se-
curities of such issuer, and (ii) in the aggregate such persons own or
would own more than 5% of such securities;
11. Make loans except (i) by purchasing bonds, debentures or similar ob-
ligations (including repurchase agreements, subject to the limitation de-
scribed in (6) above), which are publicly distributed, and (ii) by lending
its securities to banks, brokers, dealers and other financial institutions
so long as such loans are not inconsistent with the Investment Company Act
or the Rules and Regulations or interpretations of the Securities and Ex-
change Commission (the "Commission") thereunder;
12. Pledge, mortgage, or hypothecate any of its assets to an extent
greater than 5% of its total assets;
13. Invest directly in interests in oil, gas or other mineral exploration
or development programs; and
14. Invest more than 25% of the value of its total assets in any one in-
dustry.
The above mentioned investment limitations are considered at the time in-
vestment securities are purchased. Notwithstanding these limitations, the Fund
may own all or any portion of the securities of, or make loans to, or contrib-
ute to the costs or other financial requirements of any company which will be
wholly-owned by the Fund and one or more other investment companies and is
primarily engaged in the business of providing, at-cost, management, adminis-
trative, distribution or related services to the Fund and other investment
companies. See "The Vanguard Group."
PURCHASE OF SHARES
The Fund reserves the right in its sole discretion (i) to suspend the offer-
ing of its shares, (ii) to reject purchase orders when in the judgment of man-
agement such rejection is in the best interest of the Fund, and (iii) to re-
duce or waive the minimum investment for or any other restrictions on initial
and subsequent investments for certain fiduciary accounts or under circum-
stances where certain economies can be achieved in sales of the Fund's shares.
REDEMPTION OF SHARES
The Fund may suspend redemption privileges or postpone the date of payment
for redeemed shares (i) during any period that the New York Stock Exchange is
closed, or trading on the Exchange is re-
B-2
<PAGE>
stricted, as determined by the Commission; (ii) during any period when an
emergency exists, as defined by the rules of the Commission, as a result of
which it is not reasonably practicable for the Fund to dispose of securities
owned by it or fairly determine the value of its assets; and (iii) for such
other periods as the Commission may permit.
No charge is made by the Fund for redemptions. Any redemption may be more or
less than the shareholder's cost, depending on the current market value of the
securities held by the Fund.
The Fund has made an election with the Commission to pay in cash all redemp-
tions requested by any shareholder of record limited in amount during any 90-
day period to the lesser of $250,000 or 1% of the net assets of the Fund at
the beginning of such period. Such commitment is irrevocable without the prior
approval of the Commission. Redemptions in excess of the above limits may be
paid in whole or in part in investment securities or in cash, as the Directors
may deem advisable; however, payment will be made wholly in cash unless the
Directors believe that economic or market conditions exist which would make
such a practice detrimental to the best interests of the Fund. If redemptions
are paid in investment securities, such securities will be valued as set forth
in the Prospectus under "The Fund's Share Price," and a redeeming shareholder
would normally incur brokerage expenses if he converted these securities to
cash.
The Fund has authorized Charles Schwab & Co., Inc. ("Schwab") to accept on
its behalf purchase and redemption orders under certain terms and conditions.
Schwab is also authorized to designate other intermediaries to accept purchase
and redemption orders on the Fund's behalf subject to those terms and condi-
tions. Under this arrangement, the Fund will be deemed to have received a pur-
chase or redemption order when Schwab or, if applicable, Schwab's authorized
designee, accepts the order in accordance with the Fund's instructions. Cus-
tomer orders that are properly transmitted to the Fund by Schwab, or if appli-
cable, Schwab's authorized designee, will be priced as follows:
If you place your order through Schwab and it is received before 3 p.m.
Eastern time on any business day, your order will be sent to Vanguard that day
and your share price will be based on the Fund's net asset value calculated at
the close of trading that day. If your order is received after 3 p.m. Eastern
time, it will be sent to Vanguard on the following business day and your share
price will be based on the Fund's net asset value calculated at the close of
trading that day.
MANAGEMENT OF THE FUND
THE VANGUARD GROUP
Vanguard Convertible Securities Fund is a member of The Vanguard Group of
Investment Companies. Through their jointly-owned subsidiary, The Vanguard
Group, Inc. ("Vanguard"), the Fund and the other Funds in the Group obtain at
cost virtually all of their corporate management, administrative and distribu-
tion services. Vanguard also provides investment advisory services on an at-
cost basis to several of the Vanguard Funds. Vanguard employs a supporting
staff of management and administrative personnel needed to provide the requi-
site services to the Funds and also furnishes the Funds with necessary office
space, furnishings and equipment. Each Fund pays its share of Vanguard's total
expenses, which are allocated among the Funds under methods approved by the
Board of Directors (Trustees) of each Fund. In addition, each Fund bears its
own direct expenses such as legal, auditing and custodian fees.
The Fund's Officers are also Officers and employees of Vanguard. No Officer
or employee owns, or is permitted to own, any securities of any external ad-
viser for the Funds.
Vanguard adheres to a Code of Ethics established pursuant to Rule 17j-1 un-
der the Investment Company Act of 1940. The Code is designed to prevent unlaw-
ful practices in connection with the purchase or sale of securities by persons
associated with Vanguard. Under Vanguard's Code of Ethics, certain Officers
and employees of Vanguard who are considered access persons are permitted to
engage in personal securities transactions. However, such transactions are
subject to procedures and guidelines
B-3
<PAGE>
substantially similar to those recommended by the mutual fund industry and ap-
proved by the U.S. Securities and Exchange Commission.
Vanguard was established and operates under a Funds' Service Agreement which
was approved by the shareholders of each of the Funds. The amounts which each
of the Funds has invested in Vanguard are adjusted from time to time in order
to maintain the proportionate relationship between each Fund's relative net
assets and its contribution to Vanguard's capital. At November 30, 1997, the
Fund had contributed capital of $13,000 to Vanguard, representing .10% of Van-
guard's capitalization. The Funds' Service Agreement provides for the follow-
ing arrangement: (1) each Vanguard Fund may invest a maximum of 0.40% of its
assets in Vanguard; and (2) there is no restriction on the maximum aggregate
cash investment that the Vanguard Funds may make in Vanguard.
MANAGEMENT
Corporate management and administrative services include: (1) executive
staff; (2) accounting and financial; (3) legal and regulatory; (4) shareholder
account maintenance; (5) monitoring and control of custodian relationships;
(6) shareholder reporting; and (7) review and evaluation of advisory and other
services provided to the Funds by third parties. During the fiscal year ended
November 30, 1997, the Fund's share of actual net costs of operation relating
to management and administrative services provided by Vanguard totaled approx-
imately $434,000.
DISTRIBUTION
Vanguard provides all distribution and marketing activities for the Funds in
the Group. Vanguard Marketing Corporation, a wholly-owned subsidiary of Van-
guard, acts as Sales Agent for the shares of the Funds, in connection with any
sales made directly to investors in the states of Florida, Missouri, New York,
Ohio, Texas and such other states as it may be required.
The principal distribution expenses are for advertising, promotional materi-
als and marketing personnel. Distribution services may also include organizing
and offering to the public, from time to time, one or more new investment com-
panies which will become members of the Group. The Directors and Officers of
Vanguard determine the amount to be spent annually on distribution activities,
the manner and amount to be spent on each Fund, and whether to organize new
investment companies.
One-half of the distribution expenses of a marketing and promotional nature
is allocated among the Funds based upon relative net assets. The remaining
one-half of those expenses is allocated among the Funds based upon each Fund's
sales for the preceding 24 months relative to the total sales of the Funds as
a Group, provided, however, that no Fund's aggregate quarterly rate of contri-
bution for distribution expenses of a marketing and promotional nature shall
exceed 125% of average distribution expense rate for the Group, and that no
Fund shall incur annual distribution expenses in excess of .02 of 1% of its
average month-end net assets. During the fiscal year ended November 30, 1997,
the Fund paid approximately $34,000 of the group's distribution and marketing
expenses, or approximately 0.02% of 1% of its average month-end assets.

DIRECTORS AND OFFICERS
The Officers of the Fund manage its day-to-day operations and are responsi-
ble to the Fund's Board of Directors. The Directors set broad policies for the

DIRECTOR/TRUSTEE COMPENSATION
The individuals in the table below serve as Directors/Trustees of all Van-
guard Funds, and each Fund pays a proportionate share of the
Directors'/Trustees' compensation. The Funds employ their officers on a shared
basis, as well. However, officers are compensated by The Vanguard Group, Inc.,
not the Funds.
INDEPENDENT DIRECTORS/TRUSTEES. The Funds compensate their independent
Directors/Trustees--that is, the ones who are not also officers of the Fund--
in three ways:
. The independent Directors/Trustees receive an annual fee for their service
to the Funds, which is subject to reduction based on absences from scheduled
Board meetings.
. The independent Directors/Trustees are reimbursed for the travel and other
expenses that they incur attending Board meetings.
. Upon retirement, the independent Directors/Trustees receive an aggregate an-
nual fee of $1,000 for each year served on the Board, up to fifteen years of
service. This annual fee is paid for ten years following retirement, or un-
til the Directors'/Trustees' death.
"INTERESTED" DIRECTORS/TRUSTEES. The Funds' interested Directors/Trustees--
Messrs. Bogle and Brennan--receive no compensation for their service in that
capacity. However, they are paid in their role as officers of The Vanguard
Group, Inc.
COMPENSATION TABLE. The following table provides compensation details for
each of the Directors. For the Fund, we list the amounts paid as compensation
and accrued as retirement benefits by the Fund for each Director. In addition,
the table shows the total amount of benefits that we expect each
Director/Trustee to receive from all Vanguard Funds upon retirement, and the
total amount of compensation paid to each Director/Trustee by all Vanguard
Funds. All information shown is for the fiscal year ended November 30, 1997.

INVESTMENT ADVISORY SERVICES
The Fund employs Oaktree Capital Management, LLC (the "Adviser") under an
investment advisory agreement dated November 1, 1996 to manage the investment
and reinvestment of the assets of the Fund and to continuously review, super-
vise and administer the Fund's investment program. The Adviser discharges its
responsibilities subject to the control of the Officers and Directors of the
Fund.
The Fund pays the Adviser an advisory fee at the end of each fiscal quarter,
calculated by applying a quarterly rate, based on the following annual per-
centage rates, to the Fund's average month-end net assets for the quarter (the
"Basic Fee"):
<TABLE>
<CAPTION>
NET ASSETS RATE
---------- ------
<S> <C>
First $100 million.................................................... 0.425%
Next $100 million..................................................... 0.400%
Next $100 million..................................................... 0.375%
Next $100 million..................................................... 0.350%
Over $400 million..................................................... 0.325%
</TABLE>
It is not intended that the funding under this contract will exceed $500
million.
Beginning November 30, 1997, the Basic Fee payment to the Adviser may be in-
creased or decreased by a Performance Fee Adjustment (the "Adjustment"). The
Adjustment shall be a percentage of the Basic Fee and shall change proportion-
ately with the investment performance of the Fund relative to the investment
performance of the First Boston Convertible Securities Index (the "Index").
The following table sets forth the Adjustment of the Basic Fee payable by the
Fund to the Adviser under the investment advisory agreement.
<TABLE>

</TABLE>
The Adjustment will be calculated as follows, using data from the table be-
low:
To calculate the Adjustment for a given quarter, (1) for the Relevant Period
for that quarter as set forth in the table below (the "Relevant Period"), the
difference between the investment performance of the Fund and the investment
performance of the Index (the "Performance Differential") will be calculated,
(2) the Performance Differential will be compared to the Performance Factor
specified by the table for that period to determine the extent to which an Ad-
justment is in order, and (3) the Adjustment will be the appropriate percent-
age of the Basic Fee* for an average quarter in that Relevant Period deter-
mined from the table above.
- --------
* For purposes of this calculation, the relevant Basic Fee is calculated by
applying the quarterly rate against average assets over the relevant period
for which performance is measured.

</TABLE>
The investment performance of the Fund for such period, expressed as a per-
centage of the net asset value per share of the Fund at the beginning of such
period, shall be the sum of: (i) the change in the net asset value per share
of the Fund during such period; (ii) the value of the cash distributions per
share of the Fund accumulated to the end of such period; and (iii) the value
of capital gains taxes per share paid or payable by the Fund on undistributed
realized long-term capital gains accumulated to the end of such period. For
this purpose, the value of distributions per share of realized capital gains,
of dividends per share paid from investment income and of capital gains taxes
per share paid or payable on undistributed realized long-term capital gains
shall be treated as reinvested in shares of the Fund at the net asset value
per share in effect at the close of business on the record date for the pay-
ment of such distributions and dividends and the date on which provision is
made for such taxes, after giving effect to such distributions, dividends and
taxes.
The "investment record" of the Index for the period, expressed as a percent-
age of the Index level at the beginning of the period, shall be the sum of (i)
the change in the level of the Index during the period and (ii) the value,
computed consistently with the Index, of cash distributions having an ex-divi-
dend date occurring within the period made by companies whose securities com-
prise the Index.
During the fiscal years ended November 30, 1995, 1996, and 1997, the Fund
paid investment advisory fees of approximately $674,000, $578,000 and $731,000
(before a decrease of $91,000 based on performance), respectively.
The agreement will continue until October 31, 1998 and will be renewable
thereafter for successive one-year periods, only if each renewal is specifi-
cally approved by a vote of the Fund's Board of Directors, including the af-
firmative votes of a majority of the Directors who are not parties to the con-
tract or "interested persons" (as defined in the Investment Company Act of
1940) of any such party, cast in person at a meeting called for the purpose of
considering such approval. In addition, the question of continuance of the
agreement may be presented to the shareholders of the Fund; in such event,
continuation must be approved by the affirmative vote of a majority of the
outstanding voting securities of the Fund. The agreement is automatically ter-
minated if assigned, and may be terminated without penalty at any time (1) ei-
ther by vote of the Board of Directors of the Fund or by vote of its outstand-
ing voting securities on 60 days' written notice to the Adviser, or (2) by the
Adviser upon 60 days' written notice to the Fund.
The Fund's Board of Directors may, without the approval of shareholders,
provide for:
A. The employment of a new investment adviser pursuant to the terms of a
new advisory agreement, either as a replacement for an existing adviser or
as an additional adviser;
B. A change in the terms of an advisory agreement; and
B-8
<PAGE>
C. The continued employment of an existing adviser, on the same advisory
contract terms, where a contract has been assigned because of a change in
control of the adviser.
Any such change will only be made upon not less than 30 days' prior written
notice to shareholders, which shall include the information concerning the ad-
viser that would have normally been included in a proxy statement.
Oaktree Capital Management, LLC specializes in selected niche investment
markets. The founders of Oaktree formed the company in April of 1995 after
having managed funds in the convertible securities, distressed debt, and high
yield bond areas of Trust Company of the West (TCW) since 1985.
Larry W. Keele, Principal and one of the five founders of Oaktree, serves as
Portfolio Manager of the Fund. Mr. Keele is supported by research and other
investment services provided by the professional staff of Oaktree. As of No-
vember 30, 1997, Oaktree managed approximately $9.7 billion.
PORTFOLIO TRANSACTIONS
The investment advisory agreement authorizes the Adviser (with the approval
of the Fund's Board of Directors) to select the brokers or dealers that will
execute the purchases and sales of portfolio securities for the Fund and di-
rects the Adviser to use its best efforts to obtain the best available price
and most favorable execution as to all transactions for the Fund. The Adviser
has undertaken to execute each investment transaction at a price and commis-
sion which provides the most favorable total cost or proceeds reasonably ob-
tainable under the circumstances.
In placing portfolio transactions, the Adviser will use its best judgment to
choose the broker most capable of providing the brokerage services necessary
to obtain best available price and most favorable execution. The full range
and quality of brokerage services available will be considered in making these
determinations. In those instances where it is reasonably determined that more
than one broker can offer the brokerage services needed to obtain the best
available price and most favorable execution, consideration may be given to
those brokers which supply investment research and statistical information and
provide other services in addition to execution services to the Fund and/or
the Adviser. The Adviser considers such information useful in the performance
of its obligations under the agreement, but is unable to determine the amount
by which such services may reduce its expenses.
The investment advisory agreement also incorporates the concepts of Section
28(e) of the Securities Exchange Act of 1934 by providing that, subject to the
approval of the Fund's Board of Directors, the Adviser may cause the Fund to
pay a broker-dealer which furnishes brokerage and research services a higher
commission than that which might be charged by another broker-dealer for ef-
fecting the same transaction; provided that such commission is deemed reason-
able in terms of either that particular transaction or the overall responsi-
bilities of the Adviser to the Fund.
Currently, it is the Fund's policy that the Adviser may at times pay higher
commissions in recognition of brokerage services felt necessary for the
achievement of better execution of certain securities transactions that other-
wise might not be available. The Adviser will only pay such higher commissions
if it believes this to be in the best interest of the Fund. Some brokers or
dealers who may receive such higher commissions in recognition of brokerage
services related to execution of securities transactions are also providers of
research information to the Adviser and/or the Fund. However, the Adviser has
informed the Fund that it will not pay higher commission rates specifically
for the purpose of obtaining research services.
Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be through such firms.
However, the Fund may place portfolio orders with qualified broker-dealers who
B-9
<PAGE>
recommend the Fund to other clients, or who act as agent in the purchase of
the Fund's shares for their clients, and may, when a number of brokers and
dealers can provide comparable best price and execution on a particular trans-
action, consider the sale of the Fund shares by a broker or dealer in select-
ing among qualified broker-dealers.
Some securities considered for investment by the Fund may also be appropri-
ate for other clients served by the Adviser. If purchase or sale of securities
consistent with the investment policies of the Fund and one or more of these
other clients serviced by the Adviser are considered at or about the same
time, transactions in such securities will be allocated among the Fund and
such other clients in a manner deemed equitable by the Adviser. During the
fiscal years ended November 30, 1995, 1996 and 1997 the Fund paid $38,822,
$111,718, and $41,776 in brokerage commissions.
GENERAL INFORMATION
DESCRIPTION OF SHARES AND VOTING RIGHTS
The Fund is a diversified open-ended investment company established under
Maryland law. The Fund's Amended and Restated Articles of Incorporation dated
April 8, 1986 permit the Directors to issue 1,000,000,000 shares of common
stock, with a $.001 par value. The Board of Directors has the power to desig-
nate one or more classes ("Portfolios") of shares of common stock and to clas-
sify or reclassify any unissued shares with respect to such Portfolios. Cur-
rently the Fund is offering shares of one portfolio.
The shares of the Fund are fully paid and non-assessable, and have no pref-
erence as to conversion, exchange, dividends, retirement or other features.
The shares have no pre-emptive rights. The shares have non-cumulative voting
rights, which means that the holders of more than 50% of the shares voting for
the election of Directors can elect 100% of the Directors if they choose to do
so. A shareholder is entitled to one vote for each full share held (and a
fractional vote for each fractional share held), then standing in his name on
the books of the Fund. On any matter submitted to a vote of shareholders, all
shares of the Fund then issued and outstanding and entitled to vote, irrespec-
tive of the class, shall be voted in the aggregate and not by class except (i)
when required by the Investment Company Act of 1940, shares shall be voted by
individual class, and (ii) when the matter does not affect any interest of a
particular class, then only shareholders of the affected class or classes
shall be entitled to vote thereon.
YIELD AND TOTAL RETURN
The yield of the Fund for the 30-day period ended November 30, 1997 was
+4.33%.
The average annual total return of the Fund for the one-, five-, and ten-
year periods ended November 30, 1997 was +14.81%, +10.96% and +13.06%, respec-
tively. The average annual total return of the Fund for the period since its
inception on June 17, 1986 was +9.74%.

APPENDIX--DESCRIPTION OF SECURITIES AND RATINGS
I. DESCRIPTION OF BOND RATINGS
Excerpts from Moody's Investors Service, Inc., ("Moody's") description of
its bond ratings: Aaa--judged to be the best quality. They carry the smallest
degree of investment risk; Aa--judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high
grade bonds; A--possess many favorable investment attributes and are to be
considered as "upper medium grade obligations"; Baa--considered as medium
grade obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically unre-
liable over any great length of time. Ba--judged to have speculative elements;
their future cannot be considered as well assured; B--generally lack charac-
teristics of the desirable investment; Caa--are of poor standing. Such issues
may be in default or there may be present elements of danger with respect to
principal or interest; Ca--speculative in a high degree; often in default; C--
lowest rated class of bonds; regarded as having extremely poor prospects.
Moody's also supplies numerical indicators 1, 2 and 3 to rating categories.
The modifier 1 indicates that the security is in the higher end of its rating
category; the modifier 2 indicates a mid-range ranking; and 3 indicates a
ranking toward the lower end of the category.
Excerpts from Standard & Poor's Corporation ("S&P") description of its four
highest bond ratings: AAA--highest grade obligations. Capacity to pay interest
and repay principal is extremely strong; AA--also qualify as high grade obli-
gations. A very strong capacity to pay interest and repay principal and dif-
fers from AAA issues only in small degree; A--regarded as upper medium grade.
They have a strong capacity to pay interest and repay principal although they
are somewhat susceptible to the adverse effects of changes in circumstances
and economic conditions than debt in higher rated categories; BBB--regarded as
having an adequate capacity to pay interest and repay principal. Whereas it
normally exhibits adequate protection parameters, adverse economic conditions
or changing circumstances are more likely to lead to a weakened capacity to
pay interest and repay principal for debt in this category than in higher
rated categories. This group is the lowest which qualifies for commercial bank
investment. BB, B, CCC, CC--predominately speculative with respect to capacity
to pay interest and repay principal in accordance with terms of the obliga-
tion; BB indicates the lowest degree of speculation and CC the highest.
S&P applies indicators "+," no character, and "-" to its rating categories.
The indicators show relative standing within the major rating categories.
