DEAR SHAREHOLDER:

    Despite the fourth quarter recovery, 2002 was the third consecutive down
year in the equity markets, making this the most severe bear market since the
Great Depression. Allegations of corporate malfeasance, concerns about corporate
earnings and instability in the international arena had a significant negative
impact on the U.S. equity markets. There was no place to hide as virtually all
industry groups suffered declines. High-grade bonds did well in 2002 as interest
rates fell significantly. However, high-yield bonds had another poor year as
credit spreads and defaults increased. Convertibles suffered through their worst
year of performance ever, but did well relative to stocks.

PERFORMANCE OF THE FUND'S SHARES

    During 2002, the Fund's shareholders realized a total return of -45.11% with
dividends reinvested. This included four quarterly dividends, which totaled
$0.71 per share. There were no capital gains in 2002. Of the dividend
distributions, $0.32 was ordinary income and $0.39 was a return of capital.

    The market price of the Fund's shares was $8.55 at the beginning of the year
and $4.16 at the end of the year. The year-end market price per share
represented a discount of 10.15% to the Fund's net asset value (NAV) of $4.63.
The Fund's shares moved from a substantial premium to a modest discount to NAV
over the course of the year. This resulted in the return on market value of
-45.11% being significantly lower than the return on NAV -20.75%.

FUND STRUCTURE, STRATEGY AND OUTLOOK

    The Fund continues to invest in companies which are concentrated in sectors
that we believe can grow more rapidly than the overall economy during the next
few years. The largest industries represented are as follows:

                                    TABLE 1:
                               INDUSTRY WEIGHTING



INDUSTRY                                  % OF NET ASSETS
--------                                  ---------------
                                       
Media                                             9.6%
Computer Software                                 9.3%
Insurance                                         8.8%
Telecommunication                                 8.4%
Electronics                                       7.9%
Commercial Services                               6.7%


    During the second half of 2002, we continued to orient the Fund towards
companies which we believe have solid financials and whose convertibles will
benefit from an economic recovery. With a contraction in high-yield credit
spreads of approximately 250 basis points in the fourth quarter of 2002, yields
on the busted convertibles (securities with a high-yield and high-conversion
premium) in the Fund declined below double digits. These securities were sold
and replaced with others that have lower conversion premiums and higher equity
sensitivity. The decline in the weighting of busted convertibles has led to an
increase in the Fund's overall equity sensitivity. As shown in Table 2 and 3,
the weighting of busted convertible securities has declined from 33.5% to 18.5%
of the Fund.

    Despite the reduction of its exposure to busted convertibles, the Fund's
combination of a high current yield (six percent) and modest exposure to both a
rising equity market and tightening credit spreads should enable it to deliver
very good performance relative to both stocks and bonds going forward.

    The new issue market for convertibles declined substantially in 2002.
Unfavorable equity markets, combined with volatility in the credit markets
conspired to cut issuance by nearly fifty percent from the record levels of
2001. Total issuance raised net proceeds of $55.3 billion through 124 issues.
This compares to net proceeds of $104.9 billion raised through 210 issues in
2001. We expect a more positive tone for the equity markets in 2003. This should
lead to an increase in convertible issuance, particularly given the need of many
companies to refinance debt and lower the overall level of debt on their balance
sheets.

    The economy continues to grow at a moderate pace. While the latest readings
on the manufacturing sector have been positive, the employment data has been
weak and consumer spending has slowed. Despite these mixed signals, we believe
the economy should strengthen, particularly in the second half of 2003. Both
monetary and fiscal policies are stimulative and financial markets are
recovering. With profits, free cash flow and balance sheets improving,
businesses should find it harder to keep postponing new investment. 2003 should
be the year in which capital spending rebounds and contributes to economic
growth.

    One of the biggest impediments to a self-sustaining economic recovery
remains investor confidence, which has been damaged by concerns over Iraq, North
Korea, and terrorism. If the risks of war and terrorism dissipate during the
next several months, confidence should improve and economic growth could be
better than expected in the

second half of 2003 and into 2004. This should lead to better returns for
stocks, high-yield bonds and equity-linked securities such as convertibles.

THE FUND'S MANAGEMENT CHANGE

    After a great deal of consultation with his family and the management of the
TCW Convertible Securities Fund, Kevin Hunter has decided to retire in 2003.
Kevin began his career at TCW in 1983 and has been a portfolio manager of the
Fund since its inception in March of 1987. After almost twenty years at TCW, he
has decided to leave the firm to spend more time with his family and pursue
personal interests.

    During this transition, Kevin will be working full-time with the Fund until
April 2003. After that time, he will phase-out his direct portfolio management
responsibilities and be available to Tom Lyon, Mohan Kapoor and other members of
the convertible team on an as needed basis through the remainder of the year. To
facilitate this process, he will maintain an office at TCW until the end of
2003.

    We want to assure the Fund's shareholders that the Convertible Group at TCW
is fully staffed and capable of continuing to manage the Fund upon Kevin
Hunter's departure. The Fund will continue to be managed under the same
philosophy, by Tom Lyon, who has co-managed the Fund since 1997. Mohan Kapoor,
who joined the Convertible Group in 1997 will now become Tom Lyon's partner and
co-manage the Fund. Additionally, Tom and Mohan will continue to be supported by
the other members of the convertible team and the extensive analytical resources
of TCW.

DIVIDEND REINVESTMENT PLAN

    Shareholders who wish to add to their investment may do so through the
Dividend Reinvestment Plan (the "Plan"). Under the Plan, your dividend is used
to purchase shares on the open market whenever shares and the related sales
commission are selling below the Fund's Net Asset Value per share. If the market
price, including commission, is selling above the Net Asset Value, you will
receive shares at a price equal to the higher of the Net Asset Value per share
on the payment date or 95% of the closing market price on the payment date.

    To enroll in the Plan, if your shares are registered in your name, write to
The Bank of New York, Church Street Station, P.O. Box #11002, New York, New York
10277-0770, or call their toll free number (800) 524-4458. If your shares are
held by a brokerage firm, please call your broker. If, however, you need
assistance, please call our investor relations department at (877) TCW-MKTS
(829-6587). As always, we would be pleased to accommodate your investment needs.

Notes to Financial Statements
--------------------------------------------------------------------------------

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

    TCW Convertible Securities Fund, Inc. (the "Fund") was incorporated in
Maryland on January 13, 1987 as a diversified, closed-end investment management
company and is registered under the Investment Company Act of 1940, as amended.
The Fund commenced operations on March 5, 1987. The Fund's investment objective
is to seek a total investment return, comprised of current income and capital
appreciation through investment principally in convertible securities. In
accordance with the requirements of new Rule 35d-1 under the 1940 Act, the Fund
will invest, under normal market conditions, at least 80% of its net assets,
plus any borrowings for investment purposes in convertible securities. The 80%
investment policy described above is non-fundamental and may be changed by the
Board of Directors to become effective upon at least 60 days' notice to
shareholders.

    The preparation of the accompanying financial statements requires management
to make estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements and the reported amounts of
income and expenses during the reporting period. Actual results could differ
from those estimates.

    The following is a summary of the significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements. The policies are in conformity with accounting principles generally
accepted in the United States of America.

SECURITY VALUATION: Securities traded on national exchanges are valued at the
last reported sales price or the mean of the current bid and asked prices if
there are no sales in the trading period. Other securities which are traded on
the over-the-counter market are valued at the mean of the current bid and asked
prices. Short-term debt securities with maturities of 60 days or less at the
time of purchase are valued at amortized cost. Other short-term debt securities
are valued on a mark-to-market basis until such time as they reach a remaining
maturity of 60 days, where upon they will be valued at amortized value using
their value of the 61st day prior to maturity.

SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME: Security transactions are
recorded on the trade date. Dividend income is recorded on the ex-dividend date,
while interest income is recorded on the accrual basis. Discounts and premiums
on securities purchased are recognized as interest income and expense,
respectively, using a constant yield to maturity method. Realized gains and
losses on investments are recorded on the basis of identified cost.

DISTRIBUTIONS: The Fund intends to distribute its investment company taxable
income quarterly and to distribute any net realized capital gains at least
annually, to the extent required for U.S. federal income tax purposes. The Board
of Directors also may, in its discretion, choose to pay distributions in excess
of net investment income and net realized capital gains, though it is not
required to do so.

    Income and capital gain distributions are determined in accordance with
income tax regulations which may differ from accounting principles generally
accepted in the United States of

                                       11

America. These differences may be primarily due to differing treatments for
losses deferred due to wash sales and spillover distributions. Permanent book
and tax basis differences relating to shareholder distributions will result in
reclassifications to paid-in-capital and may affect net investment income per
share.

    The Fund reclassified $26,499,517 between undistributed net investment
income and paid in capital at December 31, 2002 as a result of permanent
differences between book and tax.

REPURCHASE AGREEMENTS: The Fund may invest in repurchase agreements secured by
U.S. Government Securities. A repurchase agreement arises when the Fund
purchases a security and simultaneously agrees to resell it to the seller at an
agreed upon future date. The Fund requires the seller to maintain the value of
the securities, marked to market daily, at not less than the repurchase price.
If the seller defaults on its repurchase obligation, the Fund could suffer
delays, collection expenses and losses to the extent that the proceeds from the
sale of the collateral are less than the repurchase price. The Fund did not
enter into any repurchase agreements for the year ended December 31, 2002.

NOTE 2--FEDERAL INCOME TAXES:

    It is the policy of the Fund to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and distribute all of
its net taxable income, including any net realized gains on investments, to its
shareholders. Therefore, no federal income tax provision is required.

    For the year ended December 31, 2002 the Fund recognized on a tax basis a
net realized loss of $61,307,425 on security transactions which will be carried
forward to 2010. The Fund also had a loss carry forward from the previous year
of $42,470,592 which will expire in 2009.

    Also for the year ended December 31, 2002, the fund distributed, on a tax
basis, $42,654,634 of which $16,155,090 is characterized as ordinary income and
$26,499,544 as return of capital.

    At December 31, 2002, net unrealized depreciation for federal income tax
purposes is comprised of the following components:

NOTE 3--INVESTMENT ADVISORY AND SERVICE FEES:

    TCW Investment Management Company (the "Advisor") is the investment advisor
of the Fund. As compensation for the services rendered, facilities provided, and
expenses borne, the Advisor is paid a monthly fee by the Fund computed at the
annual rate of 0.75% of the first $100 million of the Fund's average net assets
and 0.50% of the Fund's average net assets in excess of $100 million.

NOTE 4--PURCHASES AND SALES OF SECURITIES:

    For the year ended December 31, 2002, purchases and sales or maturities of
investment

securities (excluding short-term investments) aggregated $206,363,939 and
$235,314,603, respectively. There were no purchases or sales of U.S. Government
securities for the year ended December 31, 2002.

NOTE 5--SECURITY LENDING:

    During the year ended December 31, 2002, the Fund lent securities to
brokers. The brokers provided collateral, which must be maintained at not less
than 100% of the value of the loaned securities, to secure the obligation. At
December 31, 2002, the cash received from the borrowing broker was invested in
short-term investments valued at $24,803,740 which is 102.3% of the value of the
loaned securities.

NOTE 6--DIRECTORS' FEES:

    Directors who are not affiliated with the Advisor received, as a group,
aggregate fees and expenses of $100,806 from the Fund for the year ended
December 31, 2002. Certain officers and/or directors of the Fund are also
officers and/or directors of the Advisor.

NOTE 7--RESTRICTED SECURITIES:

    The Funds are permitted to invest in securities that are subject to legal or
contractual restrictions on resale. These securities generally may be resold in
transactions exempt from registration or to the public if the securities are
registered. Disposal of these securities may involve time consuming negotiations
and expense, and prompt sale at an acceptable price may be difficult. There are
no restricted securities (excluding 144A issues) at December 31, 2002.

NOTE 8--COMMON STOCK SUBSCRIPTION RIGHTS:

    Non-transferable rights to subscribe to shares of the Fund's common stock
were issued to shareholders of record on June 29, 2001. The rights entitled the
shareholders to acquire one share of newly issued common stock for four rights
held. At the termination of the subscription period on August 2, 2001, 8,450,030
shares of common stock were subscribed at a price of $7.77 per share.

Independent Auditors' Report
--------------------------------------------------------------------------------

TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
OF TCW CONVERTIBLE SECURITIES FUND, INC.:

    We have audited the accompanying statement of assets and liabilities of TCW
Convertible Securities Fund, Inc., (the "Fund"), including the schedule of
investments, as of December 31, 2002 and the related statement of operations for
the year then ended, the statements of changes in 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. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of December 31, 2002 by correspondence with the custodian.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Fund as of December 31, 2002, 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 accounting principles generally accepted in
the United States of America.
