TCW Strategic Income Fund, Inc.


Notes to Schedule of Investments (Unaudited)		March 31, 2010

Note 1—Significant Accounting Policies:

TCW Strategic Income 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, and is traded on the New York Stock Exchange under the symbol TSI. The Fund commenced operations on March 5, 1987. The Fund’s investment objective is to seek a total return comprised of current income and capital appreciation by investing in convertible securities, marketable equity securities, investment-grade debt securities, high-yield debt securities, options, securities issued or guaranteed by the United States Government, its agencies and instrumentalities (“U.S. Government Securities”), repurchase agreements, mortgage related securities, asset-backed securities, money market securities and other securities without limit believed by the Fund’s investment advisor to be consistent with the Fund’s investment objective. TCW Investment Management Company (the “Advisor”) is the investment advisor to the Fund and is registered under the Investment Advisers Act of 1940.

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 61^st day prior to maturity.

Securities for which market quotations are not readily available, including circumstances under which it is determined by the Advisor that sale or mean prices are not reflective of a security’s market value, are valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Fund’s Board of Directors. There were no fair valued securities at March 31, 2010.

Fair value is defined as the price that a fund would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is utilized to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk — for example, the risk inherent in a particular valuation technique used to measure fair value and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below.

Level 1 – quoted prices in active markets for identical investments

Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

The following is a summary of the inputs used as of March 31, 2010 in valuing the Fund’s investments:

Following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining value:


Investments in Securities	Balance as of 12/31/09		Accrued Discounts (Premiums)		Realized Gain/Loss and Change in Unrealized Appreciation/ (Depreciation)			Net Purchases (Sales)			Net Transfers in and/or Out of Level 3		Balance as of 03/31/10		Net Change in Unrealized Appreciation/ (Depreciation) from Investments Still Held as of 03/31/10

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.

At March 31, 2010, net unrealized appreciation (depreciation) for federal income tax purposes is comprised of the following components:


Appreciated securities	$	38,930,094
Depreciated securities		(13,927,125	)

Net unrealized appreciation/(depreciation)	$	25,002,969

Cost of securities for federal income tax purposes	$	245,553,124

The Fund did not have any unrecognized tax benefits at March 31, 2010, nor were there any increases or decreases in unrecognized tax benefits for the period then ended; and therefore no interest or penalties were accrued. The Fund is subject to examination by U.S. federal and state tax authorities for returns filed for the prior three and four fiscal years, respectively.

Note 3—Security Lending:

The Fund can lend securities to brokers. The brokers must provide collateral, which must be maintained at not less than 100% of the value of the loaned securities, to secure the obligation. The Fund receives income, net of broker fees, by investing the collateral. The Fund did not lend securities any time during the three months ended March 31, 2010.

Note 4—Restricted Securities:

The Fund is permitted to invest in securities that are subject to legal or contractual restrictions on resale. These securities 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 were no restricted securities (excluding Rule 144A issues) at March 31, 2010. However, certain 144A securities were deemed illiquid as of March 31, 2010 and therefore were considered restricted. Aggregate cost and fair value of such securities held at March 31, 2010 were as follows:


	Aggregate Cost		Aggregate Value		Value as a Percentage of Fund’s Net Assets
Total of Restricted Securities	$	1,516,398	$	1,626,982	0.66	%

Note 5—Recently Issued Accounting Pronouncements

In January 2010, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about Fair Value Measurements.” ASU No. 2010-06 clarifies existing disclosure and requires additional disclosures regarding fair value measurements. Effective for interim and annual reporting periods beginning after December 15, 2009, entities will be required to disclose significant transfers into and out of Level 1 and 2 measurements in the fair value hierarchy and the reasons for those transfers. Effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years, entities will need to disclose information about purchases, sales, issuances and settlements of Level 3 securities on a gross basis, rather than as a net number as currently required. Management is currently evaluating the impact ASU No. 2010-06 will have on its financial statement disclosures.

Note 6—Subsequent Events:

The Advisor has evaluated the possibility of subsequent events existing in this report through May 7, 2010. The Advisor has determined that there are no material events that would require recognition or disclosure in this report through this date.
