Edgar Filing: TCW CONVERTIBLE SECURITIES FUND INC

Note 1 – Significant Accounting Policies:

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 on the 61^st day prior to maturity.

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.

Notes to Schedule of Investments (Unaudited)

September 30, 2005

TCW Convertible Securities Fund, Inc. (the “‘Fund”) was incorporated in the State of Maryland on January 13, 1987 as a diversified, closed-end investment management company and is registered under the Investment Company Act of 1940 (the “1940 Act”), 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 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.

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 period ended September 30, 2005.

At September 30, 2005, net unrealized appreciation for federal income tax purposes is comprised of the following components:

Appreciated securities	$	19,809,866
Depreciated securities	(12,358,242		)
Net unrealized appreciation	$	7,451,624
Cost of securities for federal income tax purposes	$	303,692,736

Note 3—Security Lending:

During the period ended September 30, 2005, the Fund lent securities to qualified 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 September 30, 2005, the cash collateral received from the borrowing brokers was $51,638,934 which is 102.17% of the value of the loaned securities. The Fund receives income, net of broker fees, by investing the cash collateral in short-term investments.

Note 4—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 September 30, 2005.

Item 2. Controls and Procedures.

(a) The Registrant’s Chief Executive Officer and Chief Financial Officer concluded that the Registrant’s disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940) were effective as of a date within 90 days prior to the filing date of this report (the “Evaluation Date”), based on their evaluation of the effectiveness of the Registrant’s disclosure controls and procedures as of the Evaluation Date.
