TCW Strategic Income Fund, Inc.

To Our Valued Shareholders

David S. DeVito President, Chief Executive Officer and Director

Dear Valued Shareholder:

TCW is pleased to present the 2017 annual report for the TCW Strategic Income Fund (“TSI” or the “Fund”). TSI is a multi-asset class closed-end fund managed by TCW Investment Management Company and is listed on the New York Stock Exchange under the ticker TSI. For 2017, the shareholders of TSI realized a 16.36% return on investment and the Fund’s net asset value (“NAV”) increased by 7.22% (i.e., returns of the underlying assets), while the TSI Custom Index gained 8.52%. The Fund’s year-to-date price based return exceeded the NAV based return which helped narrow the discount between NAV and share price from 8.3% at the beginning of the year to 0.68% by December 31, 2017. Annualized price based performance for the trailing 3-Year period and longer remained well ahead of the Fund’s benchmark.

In 2017, the Fund paid quarterly dividends of $0.055, $0.055, $0.0575, and $0.147 per share, respectively for each of the four quarters. The fourth quarter distribution of $0.147 per share included a capital gain distribution of $0.033 per share.

The market value and net asset value of the Fund’s shares will fluctuate with market conditions.

You should not draw any conclusions about the Fund’s performance from the amount of the quarterly distribution or from the terms of the Fund’s distribution policy.

(3) Inception date of the Fund.

Management Commentary

TCW manages the Fund’s portfolio of securities according to a full cycle discipline. Effectively, this means that our management style opportunistically increases the level of risk taking with respect to the assets in the early years of an asset price/credit cycle. In the latter stages of the cycle, our proclivity is to reduce risk, which naturally also has the tendency to pull down the overall yield of the portfolio. TCW currently judges the cycle to be in its later stages and hence the portfolio has been actively de-risked across a number of different dimensions. Of course, price volatility can never be eliminated nor can the future be judged with any certainty. That said, management’s efforts to de-risk the portfolio, while causing portfolio yield to remain modest, also have the effect of somewhat mitigating the impact of market de-leveraging events.

Our belief that the cycle has entered a late stage is predicated on a number of observations. These include:

1. High and rising leverage within the corporate debt sector

2. Worsening loss and delinquency trends within consumer credit, especially in the auto and credit card lending arenas

3. A flattening trend in terms of bank commercial and industrial lending

4. Probable reductions in global central bank stimulus and an apparent inability of the Fed to “normalize” rates

1

5. Substantial declines in market based volatility metrics

6. “Cycle tights” in terms of the flatness of the yield curve, i.e., a narrowing of the yield between longer dated and shorter dated debt securities

Management is therefore currently focused on investment securities and strategies that draw from the relatively safer sectors of the market. These include (but are not limited to) private label, “legacy” non-agency mortgage-backed securities, AAA-rated commercial mortgages, government guaranteed student loan securitizations, and investment grade corporate debt.

We greatly appreciate your investment in the Fund and your continuing support of TCW. If you have any additional questions or comments, we invite you to visit our web site at www.tcw.com or contact our shareholder services department at 1-866-227-8179, or contact@tcw.com.

Sincerely,

David S. DeVito

President, Chief Executive Officer and Director

Notes to Financial Statements

Note 1 — Organization

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 (the “1940 Act”). Its shares are 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 a wide range of securities including convertible securities, marketable equity securities, investment-grade debt securities, high-yield debt securities, securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities (“U.S. Government Securities”), repurchase agreements, mortgage related securities, asset-backed securities, money market securities, other securities and derivative instruments without limit believed by the Fund’s investment advisor to be consistent with the Fund’s investment objective. TCW Investment Management Company LLC (the “Advisor”) is the investment advisor to the Fund and is registered under the Investment Advisers Act of 1940, as amended.

Note 2 — Significant Accounting Policies

The following is a summary of significant accounting policies, which are in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and which are consistently followed by the Fund in the preparation of its financial statements. The Fund is considered an investment company under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) No. 946, Financial Services — Investment Companies.

Principles of Accounting:    The Fund uses the accrual method of accounting for financial reporting purposes.

Security Valuation:    Securities traded on national exchanges are valued at the last reported sales price. Securities traded on the NASDAQ Stock Market (“NASDAQ”) are valued using the NASDAQ Official Closing Price, which may not be the last reported sales price. Other securities, including short-term investments and forward currency contracts, which are traded over-the-counter (“OTC”) are valued at the mean of the current bid and asked prices as furnished by independent pricing services or by dealer quotations. Futures contracts are valued at the official settlement price of the exchange where they are traded.

Securities for which market quotations are not readily available, including in circumstances under which it is determined by the Advisor that prices received are not reflective of their market values, are valued by the Advisor’s Pricing Committee in accordance with the guidelines established by the Board’s Valuation Committee and under the general oversight of the Board.

Fair value is defined as the price that the 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. In accordance with the authoritative guidance on fair value measurements and disclosures under GAAP, the Fund discloses investments in a three-tier hierarchy. This hierarchy is utilized to establish classification of fair value measurement and refers broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. 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 inputs market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

24

TCW Strategic Income Fund, Inc.

December 31, 2017

Note 2 — Significant Accounting Policies (Continued)

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)

Changes in valuation techniques may result in transfers in or out of an investment’s assigned level within the hierarchy. The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to each security.

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.

In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition, as well as changes related to liquidity of investments, could cause a security to be reclassified between Level 1, Level 2, or Level 3.

In certain cases, 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 is determined based on the lowest level input that is significant to the fair value measurement.

Fair Value Measurements:    Descriptions of the valuation techniques applied to the Fund’s major categories of assets and liabilities on a recurring basis are as follows:

Asset-backed securities (“ABS”) and mortgage-backed securities (“MBS”).    The fair value of ABS and MBS is estimated based on pricing models that consider the estimated cash flows of each debt tranche of the issuer, establish a benchmark yield, and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche including, but not limited to, the prepayment speed assumptions and attributes of the collateral. To the extent the inputs are observable and timely, the values would be categorized in Level 2 of the fair value hierarchy; otherwise, they would be categorized in Level 3.

Corporate bonds.    The fair value of corporate bonds is estimated using recently executed transactions, market price quotations (where observable), bond spreads, or credit default swap spreads adjusted for any basis difference between cash and derivative instruments. Corporate bonds are generally categorized in Level 2 of the fair value hierarchy.

Foreign currency contracts.    The fair value of foreign currency contracts is derived from indices, reference rates, and other inputs or a combination of these factors. To the extent that these factors can be observed, foreign currency contracts are categorized in Level 2 of the fair value hierarchy.

Futures contracts.    Futures contracts are generally valued at the settlement price established at the close of business each day by the exchange on which they are traded. As such, they are categorized in Level 1.

Notes to Financial Statements (Continued)

Note 2 — Significant Accounting Policies (Continued)

Government and agency securities.    Government and agency securities are normally valued using a model that incorporates market observable data such as reported sales of similar securities, broker quotes, yields, bids, offers, quoted market prices, and reference data. Accordingly, government and agency securities are normally categorized in Level 1 or 2 of the fair value hierarchy depending on the liquidity and transparency of the market.

Money market funds.    Money market funds are open-end mutual funds that invest in short-term debt securities. To the extent that these funds are valued based upon the reported net asset value (“NAV”), they are categorized in Level 1 of the fair value hierarchy.

Municipal bonds.    Municipal bonds are fair valued based on pricing models that take into account, among other factors, information received from market makers and broker-dealers, current trades, bid wants lists, offerings, market movements, the callability of the bond, state of issuance, benchmark yield curves, and bond insurance. To the extent that these inputs are observable and timely, the fair values of municipal bonds would be categorized in Level 2; otherwise, the fair values would be categorized in Level 3.

Restricted securities.    Restricted securities, including illiquid Rule 144A securities, issued by non-public entities are included in Level 3 of the fair value hierarchy because they trade infrequently, and therefore, the inputs are unobservable. Any other restricted securities valued similar to publicly traded securities may be categorized in Level 2 or 3 of the fair value hierarchy depending on whether a discount is applied and significant to the fair value.

Short-term investments.    Short-term investments are valued using market price quotations, and are reflected in Level 2 of the fair value hierarchy.

The summary of the inputs used as of December 31, 2017 is listed after the Investments by Sector or Industry table.

The Fund did not have any transfers in and out of Level 1 and Level 2 of the fair value hierarchy during the year ended December 31, 2017.

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

* The valuation technique employed on the Level 3 securities involves the use of third-party broker quotes and vendor prices. The Advisor monitors the effectiveness of third-party brokers and vendor prices using the Advisor’s own model and inputs.

Security Transactions and Related Investment Income:    Security transactions are recorded as of the trade date. Dividend income is recorded on the ex-dividend date. Interest income is recognized on an accrual basis. Realized gains and losses on investments are recorded on the basis of specific identification.

Foreign Currency Translation:    The books and records of the Fund are maintained in U.S. dollars as follows: (1) the foreign currency denominated securities and other assets and liabilities stated in foreign currencies are translated using the daily spot rate; and (2) purchases, sales, income and expenses are translated at the rate of exchange prevailing on the respective dates of such transactions. The resultant exchange gains and losses are included in net realized or net unrealized gain (loss) in the Statement of Operations. Pursuant to U.S. federal income tax regulations, certain foreign exchange gains and losses included in realized and unrealized gains and losses are included in, or are a reduction of, ordinary income for federal income tax purposes.

Distributions:    Distributions to shareholders are recorded on each ex-dividend date. The Fund declared and paid or reinvested dividends quarterly under an income-based distribution policy. The income-based distribution policy has a stated goal of providing quarterly distributions out of the Fund’s accumulated undistributed net investment income and/or other sources subject to the requirements of the 1940 Act and Sub-chapter M of the Internal Revenue Code (the “Code”). The source for the dividend can come from net investment income and net realized capital gains measured on a fiscal year basis. Any portion of the distribution that exceeds income and capital gains will be treated as a return of capital. Under certain conditions, federal tax regulations cause some or all of the return of capital to be taxed as ordinary income. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from GAAP. These differences may be primarily due to differing treatments for market discount and premium, losses recognized on structured debt, losses deferred due to wash sales, foreign currency gains and losses, 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.

Note 2 — Significant Accounting Policies (Continued)

Derivative Instruments:    Derivatives are financial instruments whose values are based on the values of one or more indicators, such as a security, asset, currency, interest rate, or index. Derivative transactions can create investment leverage and may be highly volatile. It is possible that a derivative transaction will result in a loss greater than the principal amount invested. The Fund may not be able to close out a derivative transaction at a favorable time or price.

For the year ended December 31, 2017, the Fund had derivatives and transactions in derivatives, grouped in the following risk categories:

(1) Represents appreciation (depreciation) of futures contracts as reported in the Schedule of Investments as of December 31, 2017. Only the variation margin is reported within the Statement of Assets and Liabilities.

(2) Amount disclosed represents average number of contracts or notional amounts, which are representative of the volume traded for the year ended December 31, 2017.

Counterparty Credit Risk:    Derivative contracts may be exposed to counterparty risk. Losses can occur if the counterparty does not perform under the contract.

The Fund’s risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund.

With exchange traded futures and centrally cleared swaps, there is less counterparty credit risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default (including the bankruptcy or insolvency) of the clearing broker or clearinghouse. Additionally, credit risk exists in exchange traded futures and centrally cleared swaps with respect to initial and variation margin

that is held in a clearing broker’s customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients, typically the shortfall would be allocated on a pro rata basis across all the clearing broker’s customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs OTC derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events. In addition, certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund’s net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA Master Agreements, which would cause the Fund to accelerate payment of any net liability owed to the counterparty.

Collateral requirements:    For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any collateral pledged or received by the Fund.

Cash collateral that has been pledged to cover obligations of the Fund is reported separately on the Statement of Assets and Liabilities. Non-cash collateral pledged by the Fund, if any, is noted in the Schedule of Investments. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold, typically $250,000 or $500,000, before a transfer is required, which is determined at the close of each business day and the collateral is transferred on the next business day. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty non-performance. The Fund attempts to mitigate counterparty risk by entering into agreements only with counterparties that the Advisor believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities. The Fund has implemented the disclosure requirements pursuant to FASB ASU No. 2013-01, Disclosures about Offsetting Assets and Liabilities that requires disclosures to make financial statements that are prepared under GAAP more comparable to those prepared under International Financial Reporting Standards.

Note 3 — Portfolio Investments

Forward Foreign Currency Contracts:    The Fund enters into forward foreign currency contracts as a hedge against fluctuations in foreign exchange rates. Forward foreign currency contracts are marked to market daily and the change in market value is recorded by the Fund as unrealized gains or losses in the Statement of Assets and Liabilities. When a contract is closed or delivery is taken, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of the foreign currency relative to the U.S. dollar. Outstanding foreign currency forward contracts as of December 31, 2017 are disclosed in the Schedule of Investments.

Futures Contracts:    The Fund seeks to manage a variety of different risks or obtain exposure through the use of futures contracts. The Fund may use index futures to hedge against broad market risks to its portfolio or to gain broad market exposure when it holds uninvested cash or as an inexpensive substitute for cash investments directly in securities or other assets. Securities index futures contracts are contracts to buy or sell units of a securities index at a specified future date at a price agreed upon when the contract is made and are settled in cash. Positions in futures may be closed out only on an exchange or board of trade which provides a secondary market for such futures. Because futures contracts are exchange-traded, they typically have minimal exposure to counterparty risk. Parties to a futures contract are not required to post the entire notional amount of the contract, but rather a small percentage of that amount (by way of margin), both at the time they enter into futures transactions, and then on a daily basis if their positions decline in value; as a result, futures contracts are highly leveraged. Such payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Because futures markets are highly leveraged, they can be extremely volatile, and there can be no assurance that the pricing of a futures contract will correlate precisely with the pricing of the asset or index underlying it or the asset or liability of the Fund that is the subject of the hedge. It may not always be possible for the Fund to enter into a closing transaction with respect to a futures contract it has entered into at a favorable time or price. When the Fund enters into a futures transaction, it is subject to the risk that the value of the futures contract will move in a direction unfavorable to it.

When the Fund uses futures contracts for hedging purposes, it is likely that the Fund will have an asset or liability that will offset any loss (or gain) on the transactions, at least in part. When a futures contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. During the year ended December 31, 2017,

30

Note 3 — Portfolio Investments (Continued)

the Fund used S&P 500 Index futures to gain exposure to the equity market. The Fund also utilized treasury and other bond futures to help manage interest rate duration and credit market exposure. Futures contracts outstanding as of December 31, 2017 are listed in the Fund’s Schedule of Investments.

Options:    The Fund may purchase and sell put and call options on securities or indexes to enhance investment performance and/or to protect against changes in market prices.

A call option gives the holder the right to purchase, and obligates the writer to sell, a security at the strike price at anytime before the expiration date. A put option gives the holder the right to sell, and obligates the writer to buy, a security at the exercise price at any time before the expiration date. The Fund may purchase put options to protect portfolio holdings against a decline in market value of a security or securities held by it. The Fund may also purchase a put option hoping to profit from an anticipated decline in the value of the underlying security. If the Fund holds the security underlying the option, the option premium and any transaction costs will reduce any profit the Fund might have realized had it sold the underlying security instead of buying the put option. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund ultimately wants to buy. The Fund may also purchase a call option as a long directional investment hoping to profit from an anticipated increase in the value of the underlying security. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

The Fund may execute transactions in both listed and OTC options. Listed options involve minimal counterparty risk since listed options are guaranteed against default by the exchange on which they trade. Transactions in certain OTC options may expose the Fund to the risk of default by the counterparty to the transaction. In the event of default by the counterparty to the OTC option transaction, the Fund’s maximum amount of loss as purchaser is the premium paid plus any unrealized gain. During the year ended December 31, 2017, the Fund did not purchase or write any option contracts.

Swap Agreements:    The Fund may enter into swap agreements. Swap agreements are typically two-party contracts entered into primarily by institutional investors. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or “swapped” between the parties are generally calculated with respect to a “notional amount” (i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a “basket” of securities representing a particular index).

The Fund may enter into credit default swap transactions as a “buyer” or “seller” of credit protection. In a credit default swap, one party provides what is in effect insurance against a default or other adverse credit event affecting an issuer of debt securities (typically referred to as a “reference entity”). In general, the buyer of credit protection is obligated to pay the protection seller an upfront amount or a periodic stream of payments over the term of the swap. If a “credit event” occurs, the buyer has the right to deliver to the seller bonds or other obligations of the reference entity (with a value up to the full notional value of the swap), and to receive a payment equal to the par value of the bonds or other obligations. Credit events that would trigger a request that the seller make payment are specific to each credit default swap agreement, but generally include bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium. When the Fund buys protection, it may or may not own securities of the reference

31

Notes to Financial Statements (Continued)

Note 3 — Portfolio Investments (Continued)

entity. When the Fund sells protection under a credit default swap, the position may have the effect of creating leverage in the Fund’s portfolio through the Fund’s indirect long exposure to the issuer or securities on which the swap is written. When the Fund sells protection, it may do so either to earn additional income or to create such a “synthetic” long position.

During the term of a swap transaction, changes in the value of the swap are recognized as unrealized gains or losses by marking to market to reflect the market value of the swap. When the swap is terminated, the Fund will record a realized gain or loss equal to the difference, if any, between the proceeds from (or cost of) the closing transaction and the Fund’s basis in the agreement. Upfront swap premium payments paid or received by the Fund, if any, are recorded within the value of the open swap agreement on the Fund’s Statement of Assets and Liabilities and represent payments paid or received upon entering into the swap agreement to compensate for differences between stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, and other relevant factors). These upfront payments are recorded as realized gain or loss on the Fund’s Statement of Operations upon termination or maturity of the swap agreement.

During the term of a swap transaction, the periodic net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate, the change in market value of a specified security, basket of securities or index, or the return generated by a security. These periodic payments received or made by the Fund are recorded as realized gains and losses, respectively. During the year ended December 31, 2017, the Fund did not enter into such agreements.

Mortgage-Backed Securities:    The Fund may invest in mortgage pass-through securities which represent interests in pools of mortgages in which payments of both principal and interest on the securities are generally made monthly, in effect “passing through” monthly payments made by borrowers on the residential or commercial mortgage loans which underlie the securities (net of any fees paid to the issuer or guarantor of the securities). Mortgage pass-through securities differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. The Fund may also invest in collateralized mortgage obligations (“CMOs”). CMOs are debt obligations collateralized by residential or commercial mortgage loans or residential or commercial mortgage pass-through securities. Interest and principal are generally paid monthly. CMOs may be collateralized by whole mortgage loans or private mortgage pass-through securities but are more typically collateralized by portfolios of mortgage pass-through securities guaranteed by Ginnie Mae, Freddie Mac or Fannie Mae. The issuer of a series of CMOs may elect to be treated for tax purposes as a real estate mortgage investment conduit. CMOs are structured into multiple classes, each bearing a different stated maturity. Monthly payment of principal received from the pool of underlying mortgages, including prepayments, is first returned to investors holding the shortest maturity class. Investors holding the longer maturity classes usually receive principal only after shorter classes have been retired. An investor may be partially protected against a sooner than desired return of principal because of the sequential payments. The Fund may invest in stripped MBS. Stripped MBS are usually structured with two classes that receive different proportions of the interest and principal distributions on a pool of mortgage assets. In certain cases, one class will receive all of the interest (the interest only or “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). The yield to maturity on IOs is sensitive to the rate of principal prepayments (including prepayments) on the related underlying mortgage assets, and principal payments may have a material effect on yield to maturity. If the underlying mortgage assets

32

Note 3 — Portfolio Investments (Continued)

experience greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IOs.

Repurchase Agreements:    The Fund may enter into repurchase agreements under the terms of a Master Repurchase Agreement (“MRA”). The MRA permits the Fund, under certain circumstances, including an event of default (such as bankruptcy or insolvency), to offset payables and/or receivables under the MRA with collateral held and/or posted to the counterparty and create one single net payment due to or from the Fund. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of the MRA counterparty’s bankruptcy or insolvency. Pursuant to the terms of the MRA, the Fund receives securities as collateral with a market value in excess of the repurchase price. Upon a bankruptcy or insolvency of the MRA counterparty, the Fund recognizes a liability with respect to such excess collateral to reflect the Fund’s obligation under bankruptcy law to return the excess to the counterparty. The Fund had no repurchase agreements outstanding as of December 31, 2017.

When-Issued, Delayed-Delivery, and Forward Commitment Transactions:    The Fund may enter into when issued, delayed-delivery or forward commitment transactions in order to lock in the purchase price of the underlying security or to adjust the interest rate exposure of the Fund’s existing portfolio. In when-issued, delayed-delivery, or forward commitment transactions, the Fund commits to purchase particular securities, with payment and delivery to take place at a future date. Although the Fund does not pay for the securities or start earning interest on them until they are delivered, it immediately assumes the risks of ownership, including the risk of price fluctuation. If the Fund’s counterparty fails to deliver a security purchased on a when issued, delayed-delivery or forward commitment basis, there may be a loss, and the Fund may have missed an opportunity to make an alternative investment.

Prior to settlement of these transactions, the value of the subject securities will fluctuate. In addition, because the Fund is not required to pay for when-issued, delayed-delivery or forward commitment securities until the delivery date, they may result in a form of leverage. To guard against this deemed leverage, the Fund monitors the obligations under these transactions and ensures that the Fund has sufficient liquid assets to cover them.

Security Lending:    The Fund may lend its securities to qualified brokers. The loans must be collateralized at all times primarily with cash although the Fund can accept money market instruments or U.S. government securities with a market value at least equal to the market value of the securities on loan. As with any extensions of credit, the Fund may bear the risk of delay in recovery or even loss of rights in the collateral if the borrowers of the securities fail financially. The Fund earns additional income for lending its securities by investing the cash collateral in short-term investments. The Fund did not lend any securities during the year ended December 31, 2017.

Use of Estimates:    The preparation of the accompanying financial statements requires management to make estimates and assumptions that affect the reported amount 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 these estimates.

Note 4 — Risk Considerations

Market Risk:    The Fund’s investments will fluctuate with market conditions, and so will the value of your investment in the Fund. You could lose money on your investment in the Fund or the Fund could underperform other investments.

33

TCW Strategic Income Fund, Inc.

Notes to Financial Statements (Continued)

Note 4 — Risk Considerations (Continued)

Liquidity Risk:    The Fund’s investments in illiquid securities may reduce the returns of the Fund because it may not be able to sell the illiquid securities at an advantageous time or price. Investments in high yield securities, foreign securities, derivatives or other securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Certain investments in private placements and Rule 144A securities may be considered illiquid investments. The Fund may invest in private placements and Rule 144A securities.

Interest Rate Risk:    The values of the Fund’s investments fluctuate in response to movements in interest rates. If rates rise, the values of debt securities generally fall. The longer the average duration of a Fund’s investment portfolio, the greater the change in value.

Mortgage-Backed and Other Asset-Backed Securities Risk:    The Fund may invest in mortgage-backed securities (“MBS”) or other asset-backed securities (“ABS”). The values of some mortgage-backed or other asset backed securities may expose the Fund to a lower rate of return upon reinvestment of principal. When interest rates rise, the value of mortgage-related securities generally will decline; however, when interest rates are declining, the value of mortgage related-securities with prepayment features may not increase as much as other fixed-income securities. The rate of prepayments on underlying mortgages will affect the price and volatility of a mortgage related security, and may shorten or extend the effective maturity of the security beyond what was anticipated at the time of purchase. If an unanticipated rate of prepayment on underlying mortgages increases the effective maturity of a mortgage-related security, the volatility of the security can be expected to increase. The value of these securities may fluctuate in response to the market’s perception of the creditworthiness of the issuers. Additionally, although mortgages and mortgage-related securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations.

Derivatives Risk:    Use of derivatives, which at times is an important part of the Fund’s investment strategy, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Investments in derivatives could cause the Fund to lose more than the principal amount invested. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Fund will achieve its objective with these transactions to reduce exposure to other risks when that would be beneficial.

Credit Risk:    The values of any of the Fund’s investments may also decline in response to events affecting the issuer or its credit rating. The lower rated debt securities in which the Fund may invest are considered speculative and are subject to greater volatility and risk of loss than investment-grade securities, particularly in deteriorating economic conditions. The value of some mortgage-related securities in which the Fund invests also may fall because of unanticipated levels of principal prepayments that can occur when interest rates decline. The Fund invests a material portion of its assets in securities of issuers that hold mortgage- and asset-backed securities and direct investments in securities backed by commercial and residential mortgage loans and other financial assets. The value and related income of these securities are sensitive to changes in economic conditions, including delinquencies and/or defaults. Continuing shifts in the market’s perception of credit quality on securities backed by commercial and residential mortgage loans and other financial assets may result in increased volatility of market prices and periods of illiquidity that can negatively impact the valuation of certain issuers held by the Fund.

MBS and ABS are characterized and classified in a variety of different ways. These classifications include a view of the securities’ cash flow structure (pass through, sequential pay, prepayment-protected, interest

34

Note 4 — Risk Considerations (Continued)

only, principal-only, etc.), the security of the claim on the underlying assets (senior, mezzanine and subordinated), as well as types of underlying collateral (prime conforming loans, prime non-conforming loans, Alt-A loans, subprime loans, commercial loans, etc.). In many cases, the classification incorporates a degree of subjectivity — a particular loan might be categorized as “prime” by the underwriting standards of one mortgage issuer while another might classify the loan as “subprime.” In addition to other functions, the risk associated with an investment in a mortgage loan must take into account the nature of the collateral, the form and the level of credit enhancement, the vintage of the loan, the geography of the loan, the purpose of the loan (refinance versus purchase versus equity take-out), the borrower’s credit quality (e.g., FICO score), and whether the loan is a first trust deed or a second lien.

Counterparty Risk:    The Fund may be exposed to counterparty risk, or the risk that an entity with which the Fund has unsettled or open transactions may default. Financial assets, which potentially expose the Fund to credit and counterparty risks, consist principally of investments and cash due from counterparties. The exposure to credit and counterparty risks with respect to these financial assets is reflected in fair values recorded in the Fund’s Statement of Assets and Liabilities.

Note 5 — Federal Income Taxes

It is the policy of the Fund to comply with the requirements of the 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.

The following table shows the character of distributed and undistributed amounts on a tax basis.

Notes to Financial Statements (Continued)

Note 5 — Federal Income Taxes (Continued)

The Fund did not have any unrecognized tax benefits at December 31, 2017, 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 6 — Investment Advisory and Service Fees

As compensation for the investment advisory 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 managed assets and 0.50% of the Fund’s average managed assets in excess of $100 million.

Note 7 — Purchases and Sales of Securities

For the year ended December 31, 2017, purchases and sales or maturities of investment securities (excluding short-term investments) aggregated to $82,029,989 and $74,990,192, respectively, for non-U.S. Government securities, and aggregated to $5,257,561 and $11,570,981, respectively, for U.S. Government securities.

Note 8 — Directors’ Fees

Directors who are not affiliated with the Advisor received, as a group, fees and expenses of $133,715 from the Fund for the year ended December 31, 2017. Directors may elect to defer receipt of their fees in accordance with the terms of a Non-Qualified Deferred Compensation Plan. Deferred compensation is included within Accrued Directors’ Fees and Expenses in the Statement of Assets and Liabilities. Certain Officers and/or Directors of the Fund are also Officers and/or Directors of the Advisor but do not receive any compensation from the Fund.

Note 9 — Restricted Securities

The Fund is permitted to invest in securities that have legal or contractual restrictions on resale. These securities may be sold privately, but are required to be registered before being sold to the public (exemption rules apply). Private placement securities are generally considered to be restricted except for those securities traded between qualified institutional investors under the provisions of Rule 144A of the Securities Act of 1933, as amended (the “Securities Act”). However, the Fund considers 144A securities to be restricted if those securities have been deemed illiquid by the Advisor. Disposal of these securities may involve time consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Restricted securities outstanding at December 31, 2017 are listed below:

Issuer Description	Acquisition Date		Acquisition Cost		Aggregate Value		Percentage of Net Assets
Citigroup Commercial Mortgage Trust, (12-GC8-XA), 1.814%, due 09/10/45		2/13/2015-2/26/2015	$	360,104	$	239,662		0.1	%

Note 10 — Loan Outstanding

The Fund is permitted to have borrowings for investment purposes. The Fund has entered into a line of credit agreement, renewed annually, with The Bank of New York Mellon which permits the Fund to borrow up to $70 million at a rate, per annum, equal to the Federal Funds Rate plus 1.00%. There is also an annual facility fee of $56,000 for the contract period. The Fund did not have any borrowings during the year ended December 31, 2017.

Note 11 — Indemnifications

Under the Fund’s organizational documents, its Officers and Directors may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Fund. In addition, the Fund entered into an agreement with each of the Directors which provides that the Fund will indemnify and hold harmless each Director against any expenses actually and reasonably incurred by the Director in any proceeding arising out of or in connection with the Director’s services to the Fund, to the fullest extent permitted by the Fund’s Articles of Incorporation and By-Laws, the Maryland General Corporation Law, the Securities Act, and the 1940 Act, each as now or hereinafter in force. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote. The Fund has not accrued any liability in connection with such indemnification.

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of TCW Strategic Income Fund, Inc. (the “Fund”), including the schedule of investments, as of December 31, 2017, 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, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of December 31, 2017, and 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.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. 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, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of December 31, 2017, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Renewal of Investment Management and Advisory Agreement

TCW Strategic Income Fund, Inc. (the “Fund”) and TCW Investment Management Company LLC (the “Advisor”) are parties to an Investment Advisory and Management Agreement (“Agreement”), pursuant to which the Advisor is responsible for managing the investments of the Fund. Unless terminated by either party, the Agreement continues in effect from year to year provided that such continuance is specifically approved at least annually by the Board of Directors of the Fund (the “Board”), including the directors who are not “interested persons” of either the Fund or the Advisor as that term is defined in the Investment Company Act of 1940, as amended (the “Independent Directors”).

On September 18, 2017, the Board approved the renewal of the Agreement for an additional one-year term from February 6, 2018 through February 5, 2019. The renewal of the Agreement was approved by the Board (including by a majority of the Independent Directors) upon the recommendation of the Independent Directors. The Independent Directors met separately by telephone on August 30, 2017, and in person on another occasion, with their independent legal counsel to review and discuss the information that had been requested on their behalf by their independent legal counsel and presented by the Advisor for their consideration. The information, material facts, and conclusions that formed the basis for their recommendation and the Board’s subsequent approval are described below.

1. Information received

Materials reviewed — During the course of each year, the Independent Directors receive a wide variety of materials relating to the services provided by the Advisor, including reports on the Advisor’s investment processes, as well as on the Fund’s investment results, portfolio composition, portfolio trading practices, compliance monitoring, shareholder services, and other information relating to the nature, extent, and quality of services provided by the Advisor to the Fund. In addition, the Board reviewed information furnished to the Independent Directors in response to a detailed request sent to the Advisor on their behalf. The information in the Advisor’s responses included extensive materials regarding the Fund’s investment results, advisory fee comparisons to advisory fees charged by the Advisor to its institutional clients, financial and profitability information regarding the Advisor, descriptions of various services provided to the Fund and to other advisory and sub-advisory clients, descriptions of functions such as compliance monitoring and portfolio trading practices, and information about the personnel providing investment management services to the Fund. The Directors also considered information provided by an independent data provider, Broadridge, comparing the investment performance and the fee and expense levels of the Fund to those of appropriate peer groups of funds. After reviewing this information, the Independent Directors requested additional information from the Advisor, which the Advisor provided and the Directors considered.

Review process — The Directors’ determinations were made on the basis of each Director’s business judgment after consideration of all the information presented. The Independent Directors reviewed advice regarding legal and industry standards provided by their independent legal counsel, including a legal memorandum from their independent legal counsel discussing their fiduciary duties related to their approval of the continuation of the Agreement. The Independent Directors also discussed these matters with their independent legal counsel, who assisted them in their review and consideration of the renewal of the Agreement. The Independent Directors discussed the renewal of the Agreement with the Advisor’s representatives and in private sessions at which no representatives of the Advisor were present. In deciding to recommend the renewal of the Agreement with respect to the Fund, the Independent Directors did not identify any single or particular piece of information that, in isolation, was the controlling factor. Each

43

TCW Strategic Income Fund, Inc.

Renewal of Investment Management and Advisory Agreement (Continued)

Independent Director may also have weighed factors differently. This summary describes the most important, but not all, of the factors considered by the Board.

2. Nature, extent, and quality of services provided by the Advisor

The Independent Directors considered the depth and quality of the Advisor’s investment management process, including its research and strong analytical capabilities; the experience, capability, and integrity of its senior management and other personnel; the relatively low turnover rates of its key personnel; the overall resources available to the Advisor; and the ability of its organizational structure to address the growth in assets over the past several years. The Independent Directors considered the ability of the Advisor to attract and retain well-qualified investment professionals, noting in particular the Advisor’s hiring of professionals in various areas over the past several years, upgrading resources in the middle office and back office operations and other areas, as well as a continuing and extensive program of infrastructure and systems enhancements. The Independent Directors also considered that the Advisor made available to its investment professionals a variety of resources and systems relating to investment management, compliance, trading, operations, administration, research, and portfolio accounting. They noted the substantial additional resources made available by TCW, as the parent company of the Advisor. The Independent Directors examined and discussed a detailed description of the extensive supplemental services provided to the Fund to support its operations and compliance, as compared to the much narrower range of services provided to the Advisor’s institutional and sub-advised clients, as well as the Advisor’s oversight and coordination of numerous outside service providers to the Fund. They further noted the high level of regular communication between the Advisor and the Directors. The Advisor explained its responsibility to supervise the activities of the Fund’s various service providers, as well as supporting the Independent Directors and their meetings, regulatory filings, and various operational personnel.

The Board and the Independent Directors concluded that the nature, extent, and quality of the services provided by the Advisor are of a high quality and have benefited and should continue to benefit the Fund and its shareholders.

3. Investment performance

The Independent Directors considered the investment results of the Fund in light of its investment objective and principal strategies. They compared the Fund’s total returns with the total returns of other funds in peer group reports prepared by Broadridge with respect to various longer and more recent periods all ended May 31, 2017. The Independent Directors reviewed information as to a peer group selection presented by Broadridge and discussed the methodology for the selection with the Advisor. In reviewing the Fund’s relative performance, the Independent Directors took into account the Fund’s strategies, distinct characteristics, asset size and diversification.

The Independent Directors noted that the Fund’s performance fell below the peer group median for all periods other than the ten-year period, but also recognized that the peer group included many funds that were not considered to be sufficiently comparable in strategy or characteristics. The Board discussed the Advisor’s explanation about the lower risk and volatility profile for the Fund compared to its peers, and noted the narrower discount of the market price of its stock compared to its net asset value over the most recent one-year period.

44

TCW Strategic Income Fund, Inc.

The Board and the Independent Directors concluded that the Advisor was implementing the Fund’s investment objective and that the Advisor’s record in managing the Fund indicates that its continued management should benefit the Fund and its shareholders over the long term.

4. Advisory fees and total expenses

The Board compared the advisory fee and total expenses of the Fund (as a percentage of average net assets) with the median advisory fee and total operating expense level of the other funds in the Broadridge peer group. The Independent Directors observed that the Fund’s advisory fee and total expenses were below the medians of the peer group funds. The Board concluded that the competitive fee charged by the Advisor, and competitive expense ratio, should benefit the Fund and its shareholders.

The Independent Directors also reviewed information regarding the advisory fees charged by the Advisor to its institutional and sub-advisory clients with similar investment mandates. They concluded that, although the fees paid by those clients generally were lower than advisory fees paid by the Fund, the differences appropriately reflected the Advisor’s more extensive services provided to the Fund and significantly greater responsibilities and expenses with respect to the Fund, including the additional risks of managing a pool of assets for public investors, administrative burdens, pricing and valuation responsibilities, the supervision of vendors and service providers, and the costs of additional infrastructure and operational resources and personnel and of complying with and supporting the more comprehensive regulatory and governance regime applicable to registered investment companies with shares listed on a stock exchange.

5. The Advisor’s costs, level of profits, and economies of scale

The Independent Directors reviewed information regarding the Advisor’s costs of providing services to the Fund, as well as the resulting level of profits to the Advisor. The Independent Directors reviewed the Advisor’s stated assumptions and methods of allocating certain costs, such as personnel costs, which constitute the Advisor’s largest operating cost. The Board and the Independent Directors recognized that the Advisor should be entitled to earn a reasonable level of profits for the services that it provides to the Fund. The Board also reviewed a comparison of the Advisor’s profitability with respect to the Fund to the profitability of certain publicly traded asset managers, which the Advisor had provided to support its view that the Advisor’s profitability was reasonable. The Board and the Independent Directors also considered the implementation of a supplemental compliance services agreement that reimburses the Advisor for a portion of its compliance and other administrative services in an amount reviewed and approved by the Board and the Independent Directors. The Board noted that the Advisor has suspended charging that fee. Based on their review, the Board and the Independent Directors concluded that they were satisfied that the Advisor’s level of profitability from its relationship with the Fund was not unreasonable or excessive.

The Board and the Independent Directors considered the extent to which potential economies of scale could be realized as the Fund grows and whether the advisory fee reflects those potential economies of scale. They noted the breakpoint under the Agreement, which results in a lower advisory fee rate as the Fund grows larger. They also recognized the Advisor’s view that the advisory fee compares favorably to peer group fees, and that expenses remain competitive even at higher asset levels. The Board and the Independent Directors recognized the benefits to the Fund of the Adviser’s substantial past and on-going investment in the advisory business that benefits the Fund, such as successfully recruiting and retaining key professional talent, systems and technology, administration, compliance, legal and infrastructure, as well as the financial pressures of competing against much larger firms and passive investment products. The Independent Directors also noted the Advisor’s explanation of the increased resources required to

45

TCW Strategic Income Fund, Inc.

Renewal of Investment Management and Advisory Agreement (Continued)

manage the Fund as a result of increased competitive pressures. The Board and the Independent Directors also recognized that the Fund benefits from receiving investment advice from an organization with other types of advisory clients rather than strictly investment companies. The Board and the Independent Directors concluded that the Advisor was satisfactorily sharing potential economies of scale with the Fund through low fees and expenses, and through reinvesting in its capabilities for serving the Fund and its shareholders.

6. Ancillary benefits

The Independent Directors considered ancillary benefits to be received by the Advisor and its affiliates as a result of the relationship of the Advisor with the Fund, including compensation for certain compliance support services. The Independent Directors concluded that any potential benefits to be derived by the Advisor from its relationships with the Fund are reasonably related to the services provided by the Advisor to the Fund.

7. Conclusions

Based on their overall review, including their consideration of each of the factors referred to above (and others), the Board and the Independent Directors concluded that the Agreement is fair and reasonable to the Fund and its shareholders, that the Fund’s shareholders received reasonable value in return for the advisory fees and other amounts paid to the Advisor by the Fund, and that the renewal of the Agreement was in the best interests of the Fund and its shareholders.

Dividend Reinvestment Plan

Shareholders who wish to add to their investment may do so by making an election to participate in the Dividend Reinvestment Plan (the “Plan”). Under the Plan, your dividend is used to purchase shares on the open market whenever shares, including the related sales commission, are selling below the Fund’s per share. You will be charged a pro-rata portion of brokerage commissions on open-market purchases under the Plan. If the market price, including commission, is selling above the NAV, you will receive shares at a price equal to the higher of the NAV per share on the payment date or 95% of the closing market price on the payment date. Generally, for tax purposes, shareholders participating in the Plan will be treated as having received a distribution from the Fund in cash equal to the value of the shares purchased from them under the Plan.

To enroll in the Plan, if your shares are registered in your name, write to Computershare, P.O. Box #50500, Louisville, KY 40233, or call toll free at (866) 227-8179. If your shares are held by a brokerage firm, please call your broker. If you participate in the Plan through a broker, you may not be able to transfer your shares to another broker and continue to participate in the Plan if your new broker does not permit such participation. If you no longer want to participate in the Plan, please contact Computershare or your broker. You may elect to continue to hold shares previously purchased on your behalf or to sell your shares and receive the proceeds, net of any brokerage commissions. If you need additional information or assistance, please call our investor relations department at (877) 829-4768 or visit our website at www.tcw.com. As always, we would be pleased to accommodate your investment needs.

Distribution policy

The Fund has a net investment income-based distribution policy. The policy is to pay quarterly distributions out of the Fund’s accumulated undistributed net investment income and/or other sources subject to the requirements of the 1940 Act and Sub-chapter M of the Code.

Distribution policies are a matter of Board discretion and may be modified or terminated at any time without prior notice. Any such change or termination may have an adverse effect on the market price for the Fund’s shares.

Conflicts

The TCW Group, Inc. and its subsidiaries, the Registrant, TCW Funds, Inc., TCW Alternative Funds, and the Metropolitan West Funds (collectively, “TCW”) has policies and controls to avoid and/or mitigate conflicts of interest across its businesses. The policies and procedures in TCW’s Code of Ethics (the “Code”) serve to address or mitigate both conflicts of interest and the appearance of any conflict of interest. The Code contains several restrictions and procedures designed to eliminate conflicts of interest relating to personal investment transactions, including (i) reporting account openings, changes, or closings (including accounts in which an Access Person has a “beneficial interest”), (ii) pre-clearance of non-exempt personal investment transactions (make a personal trade request for Securities) and (iii) the completion of timely required reporting (Initial Holdings Report, Quarterly Transactions Report, Annual Holdings Report and Annual Certificate of Compliance).

In addition, the Code addresses potential conflicts of interest through its policies on insider trading, anti-corruption, an employee’s outside business activities, political activities and contributions, confidentiality and whistleblower provisions.

Conflicts of interest may also arise in the management of accounts and investment vehicles. These conflicts may raise questions that would allow TCW to allocate investment opportunities in a way that favors certain accounts or investment vehicles over other accounts or investment vehicles, or incentivize a TCW portfolio manager to receive greater compensation with regard to the management of certain account or investment vehicles. TCW may give advice or take action with certain accounts or investment vehicles that could differ from the advice given or action taken on other accounts or investment vehicles. When an investment opportunity is suitable for more than one account or investment vehicle, such investments will be allocated in a manner that is fair and equitable under the circumstances to all TCW clients. As such, TCW has adopted compliance policies and procedures in its Portfolio Management Policy that helps to identify a conflict of interest and then specifies how a conflict of interest is managed. TCW’s Trading and Brokerage Policy also discusses the process of timing and method of allocations, and addresses how the firm handles affiliate transactions.

The respective Equity and Fixed Income Trading and Allocation Committees review trading activities on behalf of client accounts, including the allocation of investment opportunities and address any issues with regard to side-by-side management in order to ensure that all of TCW’s clients are treated on a fair and equitable basis. Further, the Portfolio Analytics Committee reviews TCW’s investment strategies, evaluates various analytics to facilitate risk assessment, changes to performance composites and benchmarks and monitors the implementation and maintenance of the Global Investment Performance Standards or GIPS® compliance.

TCW’s approach to handling conflicts of interest is multi-layered starting with its policies and procedures, reporting and pre-clearance processes and oversight by various committees.

(a)(3) Portfolio Manager Compensation

The overall objective of TCW Investment Management Company LLC’s (“Advisor”) compensation program for portfolio managers is to attract experienced and expert investment professionals and to retain them over the long-term. Compensation is comprised of several components which, in the aggregate, are designed to achieve these objectives and to reward the portfolio managers for their contributions to the successful performance of the accounts they manage. Portfolio managers are compensated through a combination of base salary, fee sharing based compensation (“fee sharing”), bonus and equity incentive participation in the Advisor’s parent company (“equity incentives”). Fee sharing and equity incentives generally represent most of the portfolio managers’ compensation. In some cases, portfolio managers are eligible for discretionary bonuses.

Salary. Salary is agreed to with portfolio managers at the time of employment and is reviewed from time to time. It does not change significantly and often does not constitute a significant part of a portfolio manager’s compensation.

Fee Sharing. Fee sharing for investment professionals is based on revenues generated by accounts in the investment strategy area for which the investment professionals are responsible. In most cases, revenues are allocated to a pool and fee sharing compensation is allocated among members of the investment team after the deduction of certain expenses (including compensation over a threshold level) related to the strategy group. The allocations are based on the investment professionals’ contributions to TCW and its clients, including qualitative and quantitative contributions.

In general, the same fee sharing percentage is used to compensate a portfolio manager for investment services related to the Registrant is generally the same as that used to compensate portfolio managers for other client accounts in the same strategy managed by the Advisor or an affiliate of the Advisor (collectively, “the TCW Advisors”). In some cases, the fee sharing pool includes revenues related to more than one product, in which case each participant in the pool is entitled to fee sharing derived from his or her contributions to all the included products.

Investment professionals are not directly compensated for generating performance fees. In some cases, the fee sharing pool is subject to fluctuation based on the relative pre-tax performance of the investment strategy composite returns, net of fees and expenses, to that of the benchmark. The measurement of performance relative to the benchmark can be based on single year or multiple year metrics, or a combination thereof. The benchmark used is the one associated with the Registrant managed by the portfolio manager as disclosed in the prospectus. Benchmarks vary from strategy to strategy but, within a given strategy, the same benchmark applies to all accounts, including the Registrant.

Discretionary Bonus/Guaranteed Minimums. Discretionary bonuses may be paid out of an investment team’s fee sharing pool, as determined by the supervisor(s) in the department. In other cases where portfolio managers do not receive fee sharing or where it is determined that the combination of salary and fee sharing does not adequately compensate the portfolio manager, discretionary bonuses may be paid by the applicable TCW Advisor. Also, pursuant to contractual arrangements, some portfolio managers received minimum bonuses.

Equity Incentives. Management believes that equity ownership aligns the interests of portfolio managers with the interests of the firm and its clients. Accordingly, TCW’s key investment professionals participate in equity incentives through ownership or participation in restricted unit plans that vest over time or unit appreciation plans of the Advisor’s parent company. The plans include the Fixed Income Retention Plan, Restricted Unit Plan and 2013 Equity Unit Incentive Plan.

Under the Fixed Income Retention Plan, certain portfolio managers in the fixed income area were awarded cash and/or partnership units in the Advisor’s parent company, either on a contractually-determined basis or on a discretionary basis. Awards under this plan were made in 2010 vested over time.

Under the Restricted Unit Plan, certain portfolio managers in the fixed income and equity areas may be awarded partnership units in the Advisor’s parent company. Awards under this plan have vested over time, subject to satisfaction of performance criteria.

Under the 2013 Equity Unit Incentive Plan, certain portfolio managers in the fixed income and equity areas are awarded options to acquire partnership units in the Advisor’s parent company with a strike price equal to the fair market value of the option at the date of grant. The options granted under this plan are subject to vesting and other conditions.
