Fund Report (unaudited)

For the year ended September 30, 2017

Market Conditions

The 12-month reporting period was characterized by a steady grind tighter in credit markets, despite pockets of intra-year volatility as concerns about global growth, monetary policy, geopolitical tensions, and commodities caused temporary market weaknesses. All of these periods, however, were brief and have resulted in positive performance in credit spreads over the period, as strong technicals and demand for the asset class mitigated any potential softness in the market.

In the final quarter of 2016, the surprise Trump win in the United States dominated the news flow in November and pervasively impacted global rates, credit spreads, and equity markets. Financial market conditions changed rapidly as investors priced in the inflationary impact of anticipated fiscal stimulus, reduced trade, and a more aggressive Federal Reserve (Fed). Pro-growth rhetoric, higher inflation expectations, and continued demand for U.S. credit created a bullish environment for U.S. credit in November 2016.

In the first quarter of 2017, U.S. investment grade spreads traded tighter as low global yields, high cash balances, and government support of credit markets around the globe created a positive environment for credit markets. During this quarter, we saw the global fixed income markets price in significant relaxation of U.S. fiscal policy, as well as economic growth, a stronger U.S. dollar, and a steeper Treasury curve.

In the second quarter of 2017, we saw continued tensions between fundamentals, valuations, and technicals in the investment grade market. U.S. banking and other financial companies' fundamentals remained strong, while industrial companies' fundamentals continued to deteriorate as the pace of leverage continued on its course. Valuations remained stretched for industrials in this quarter, while financials continued to present attractive relative value opportunities. Technicals remained strong across the market. This quarter was characterized by low volatility, with spreads trading in a narrow range.

The third quarter of 2017 was positive for risk assets. Global credit traded stronger over the period, as spreads tightened across investment grade and high yield markets. While August 2017 reset valuations in the market, due to heightened geopolitical risks, the remainder of the quarter was defined by a steady grind tighter in credit fueled by strong technicals, a positive macroeconomic backdrop, low volatility, and strong equity performance.

Over the 12-month reporting period, Treasury yields were higher and the Treasury curve flattened. Specifically, the 2-, 5-, 10- and 30-year Treasury yields ended 72, 79, 74 and 54 basis points higher, respectively.¹

Credit spreads ended the period tighter. The corporate sector as a whole was 37 basis points tighter over the 12-month period.² In aggregate, BBB corporate spreads contracted 47 basis points, while single A corporate spreads were 32 basis points tighter.² Financials outperformed non-financials, with industrials spreads narrowing 35 basis points and financials tightening 44 basis points.²

Performance Analysis

The net asset value (NAV) of Morgan Stanley Income Securities Inc. (ICB) decreased from $19.73 per share on September 30, 2016, to $19.53 per share on September 30, 2017. Based on the NAV change plus reinvestment of dividends totaling approximately $0.73 per share, the Fund's total NAV return for the 12-month period was 3.09 percent. ICB's value on the New York Stock Exchange (NYSE) moved from $18.92 per share on September 30, 2016, to $18.30 per share on September 30, 2017. Based on this change plus reinvestment of dividends, the Fund's total market return for the 12-month period was 0.73 percent. ICB's NYSE market price was at a 6.3 percent discount to its NAV on September 30, 2017. Past performance is no guarantee of future results.

The monthly dividend declared in October 2017 was unchanged at $0.0425 per share. The dividend reflects the current level of the Fund's net investment income.

The Fund's investment grade credit exposure was a negative contributor to the Fund's returns, as the Fund is underweight the asset class and credit markets rallied and credit spreads tightened across sectors and maturities over the 12-month period. The Fund's emphasis on financial institutions, specifically the banking sector, however was advantageous for performance over the reporting period. The Fund has an underweight allocation to industrials, attributable to weaker relative fundamentals and less favorable relative value within the industrials segment of the market. The industrials underweight detracted from performance over the period, driven mainly by positioning in technology and consumer non-cyclicals.

An opportunistic allocation to below investment grade (or high yield) credits contributed significantly to the Fund's performance. Similarly, an allocation to convertible bonds generated positive performance for the Fund over the period, as equities performed well.

Accommodative policy and low global yields remain supportive of global credit, particularly U.S. credit, and we continue to believe the strong technical environment in global credit markets suggests modest tightening into year-end.

Technicals continue to support the asset class, and fundamentals remain positive in certain sectors of the market. At current valuations, we do not anticipate a drastic move tighter in spreads; however, we believe

spreads could continue to grind tighter into year-end if the current backdrop persists. As we head into year-end, we are vigilant of global political headlines and will continue to monitor their potential impact on credit markets.

Despite our favorable outlook on investment grade corporates, we remain cognizant that the business cycle is maturing. Company behavior in later-cycle environments is often tilted in favor of equity holders at the expense of bond holders. As a result, we remain reliant upon our active, value-oriented approach and bottom-up credit research process to help identify the best value opportunities, while avoiding those companies where we believe there is limited scope to earn attractive returns.

Given this view, the portfolio is positioned to be underweight credit risk as a whole. Specifically, the portfolio is overweight financials and underweight industrials. We continue to believe that the fundamental story in the financial sector remains strong, as banks have spent years shoring up balance sheets, increasing their liquidity profiles, and reducing risky activities. In the non-financial segment of the investment grade market, the portfolio is underweight, due to relatively weaker fundamentals and stretched valuations.

The portfolio continues to hold allocations to high yield bonds, as we believe that both fundamentals and valuations may well compensate investors for bearing risk.

The Fund's procedure for reinvesting all dividends and distributions in common shares is through purchases in the open market. This method helps support the market value of the Fund's shares. In addition, we would like to remind you that the Directors have approved a share repurchase program whereby the Fund may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at the time of purchase.

Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. Investment return, net asset value and common share market price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost.

There is no guarantee that any sectors mentioned will continue to perform as discussed herein or that securities in such sectors will be held by the Fund in the future.

1. Organization and Accounting Policies

Morgan Stanley Income Securities Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a diversified, closed-end management investment company. The Fund applies investment company accounting and reporting guidance. The Fund's primary investment objective is to provide as high a level of current income for distribution to shareholders as is consistent with prudent investment risk and, as a secondary objective, capital appreciation. The Fund was organized as a Maryland corporation on December 21, 1972 and commenced operations on April 6, 1973.

The following is a summary of significant accounting policies:

A. Valuation of Investments — (1) Certain portfolio securities may be valued by an outside pricing service/vendor approved by the Fund's Board of Directors (the "Directors"). The pricing service/vendor may employ a pricing model that takes into account, among other things, bids, yield spreads, and/or other market data and specific security characteristics. Alternatively, if a valuation is not available from an outside pricing service/vendor, and the security trades on an exchange, the security may be valued at its latest reported sale price (or at the exchange official closing price if such exchange reports an official closing price), prior to the time when assets are valued. If there are no sales on a given day and if there is no official exchange closing price for that day, the security is valued at the mean between the last reported bid and asked prices if such bid and asked prices are available in the relevant exchanges; (2) portfolio securities for which over-the-counter ("OTC") market quotations are readily available are valued at its latest reported sales price (or at the market official closing price if such market reports an official closing price), and if there was no trading in the security on a given day and if there is no official closing price from relevant markets for that day, the security is valued at the mean between the last reported bid and asked prices if such bid and asked prices are available on the relevant markets; (3) futures are valued at the settlement price on the exchange on which they trade or, if a settlement price is unavailable, at the last sale price on the exchange; (4) OTC swaps may be valued by an outside pricing service approved by the Directors or quotes from a broker or dealer. Swaps cleared on a clearinghouse or exchange may be valued using the closing price provided by the clearinghouse or exchange; (5) when market quotations are not readily available, including circumstances under which Morgan Stanley Investment Management Inc. (the "Adviser"), a wholly-owned subsidiary of Morgan Stanley, determines that the market quotations are not reflective of a security's market value, portfolio securities are valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Directors; and (6) quotations of foreign portfolio securities, other assets and liabilities and forward contracts stated in foreign currency are translated into U.S. dollar equivalents at the prevailing market rates prior to the close of the New York Stock Exchange ("NYSE").

The Directors have responsibility for determining in good faith the fair value of the investments, and the Directors may appoint others, such as the Fund's Adviser or a valuation committee, to assist the

21

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

Directors in determining fair value and to make the actual calculations pursuant to the fair valuation methodologies previously approved by the Directors. Under procedures approved by the Directors, the Fund's Adviser has formed a Valuation Committee whose members are approved by the Directors. The Valuation Committee provides administration and oversight of the Fund's valuation policies and procedures, which are reviewed at least annually by the Directors. These procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers, and other market sources to determine fair value.

The Fund has procedures to determine the fair value of securities and other financial instruments for which market prices are not readily available. Under these procedures, the Valuation Committee convenes on a regular and ad hoc basis to review such securities and considers a number of factors, including valuation methodologies and significant unobservable valuation inputs, when arriving at fair value. The Valuation Committee may employ a market-based approach which may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information for the investment to determine the fair value of the investment. An income-based valuation approach may also be used in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed. The Valuation Committee employs various methods for calibrating these valuation approaches including a regular review of valuation methodologies, key inputs and assumptions, transactional back-testing or disposition analysis, and reviews of any related market activity.

B. Accounting for Investments — Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Dividend income and other distributions are recorded on the ex-dividend date. Discounts are accreted and premiums are amortized over the life of the respective securities and are included in interest income. Interest income is accrued daily as earned.

C. Dividends and Distributions to Shareholders — Dividends and distributions to shareholders are recorded on the ex-dividend date. Dividends from net investment income, if any, are declared and paid monthly. Net realized capital gains, if any, are distributed at least annually.

D. Foreign Currency Translation and Foreign Investments — The books and records of the Fund are maintained in U.S. dollars. Foreign currency amounts are translated into U.S. dollars as follows:

— investments, other assets and liabilities at the prevailing rate of exchange on the valuation date;

— investment transactions and investment income at the prevailing rates of exchange on the dates of such transactions.

22

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

Although the net assets of the Fund are presented at the foreign exchange rates and market values at the close of the period, the Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the fluctuations arising from changes in the market prices of securities held at period end. Similarly, the Fund does not isolate the effect of changes in foreign exchange rates from the fluctuations arising from changes in the market prices of securities sold during the period. Accordingly, realized and unrealized foreign currency gains (losses) on investments in securities are included in the reported net realized and unrealized gains (losses) on investment transactions and balances. However, pursuant to U.S. federal income tax regulations, gains and losses from certain foreign currency transactions and the foreign currency portion of gains and losses realized on sales and maturities of foreign denominated debt securities are treated as ordinary income for U.S. federal income tax purposes.

Net realized gains (losses) on foreign currency transactions represent net foreign exchange gains (losses) from foreign currency forward exchange contracts, disposition of foreign currencies, currency gains (losses) realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent amounts actually received or paid. Net unrealized currency gains (losses) from valuing foreign currency denominated assets and liabilities at period end exchange rates are reflected as a component of unrealized appreciation (depreciation) in the Statement of Assets and Liabilities. The change in unrealized currency gains (losses) on foreign currency translations for the period is reflected in the Statement of Operations.

Foreign security and currency transactions may involve certain considerations and risks not typically associated with those of U.S. dollar denominated transactions as a result of, among other factors, fluctuations of exchange rates in relation to the U.S. dollar, the possibility of lower levels of governmental supervision and regulation of foreign securities markets and the possibility of political or economic instability.

E. Use of Estimates — The preparation of financial statements in accordance with generally accepted accounting principles in the United States ("GAAP") requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates.

F. Indemnifications — The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

2. Fair Valuation Measurements

Financial Accounting Standards Board ("FASB") Accounting Standards Codification^TM ("ASC") 820, "Fair Value Measurement" ("ASC 820"), defines fair value as the value that the Fund would receive to sell an investment or pay to transfer a liability in a timely transaction with an independent buyer in the principal market, or in the absence of a principal market, the most advantageous market for the investment or liability. ASC 820 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in valuing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs); and (2) inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in valuing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Fund's investments. The inputs are summarized in the three broad levels listed below.

•  Level 1 — unadjusted 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. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, or the appropriate stock exchange (for exchange-traded securities), analysis of the issuer's financial statements or other available documents and, if necessary, available information concerning other securities in similar circumstances

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each security.

The following is a summary of the inputs used to value the Fund's investments as of September 30, 2017.

Total	$	(6,424	)	$	172,438,796		$	—	$	172,432,372

Transfers between investment levels may occur as the markets fluctuate and/or the availability of data used in an investment's valuation changes. The Fund recognizes transfers between the levels as of the end of the period. As of September 30, 2017, the Fund did not have any investments transfer between investment levels.

3. Derivatives

The Fund may, but it is not required to, use derivative instruments for a variety of purposes, including hedging, risk management, portfolio management or to earn income. Derivatives are financial instruments whose value is based, in part, on the value of an underlying asset, interest rate, index or financial instrument. Prevailing interest rates and volatility levels, among other things, also affect the value of derivative instruments. A derivative instrument often has risks similar to its underlying asset and may have additional risks, including imperfect correlation between the value of the derivative and the underlying asset, risks of default by the counterparty to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative instrument relates, risks that the transactions may not be liquid and risks

25

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

arising from margin requirements. The use of derivatives involves risks that are different from, and possibly greater than, the risks associated with other portfolio investments. Derivatives may involve the use of highly specialized instruments that require investment techniques and risk analyses different from those associated with other portfolio investments. All of the Fund's holdings, including derivative instruments, are marked-to-market each day with the change in value reflected in unrealized appreciation (depreciation). Upon disposition, a realized gain or loss is recognized.

Certain derivative transactions may give rise to a form of leverage. Leverage magnifies the potential for gain and risk of loss. Leverage associated with derivative transactions may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet earmarking or segregation requirements, pursuant to applicable Securities and Exchange Commission rules and regulations, or may cause the Fund to be more volatile than if the Fund had not been leveraged. Although the Adviser seeks to use derivatives to further the Fund's investment objectives, there is no assurance that the use of derivatives will achieve this result.

Following is a description of the derivative instruments and techniques that the Fund used during the period and their associated risks:

Foreign Currency Forward Exchange Contracts — In connection with its investments in foreign securities, the Fund entered into contracts with banks, brokers or dealers to purchase or sell securities or foreign currencies at a future date. A foreign currency forward exchange contract ("currency contract") is a negotiated agreement between the contracting parties to exchange a specified amount of currency at a specified future time at a specified rate. The rate can be higher or lower than the spot rate between the currencies that are the subject of the contract. Currency contracts may be used to protect against uncertainty in the level of future foreign currency exchange rates or to gain or modify exposure to a particular currency. To the extent hedged by the use of currency contracts, the precise matching of the currency contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. Furthermore, such transactions may reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken. There is additional risk to the extent that currency contracts create exposure to currencies in which the Fund's securities are not denominated. Unanticipated changes in currency prices may result in poorer overall performance for the Fund than if it had not entered into such contracts. The use of currency contracts involves the risk of loss from the insolvency or bankruptcy of the counterparty to the contract or the failure of the counterparty to make payments or otherwise comply with the terms of the contract. A currency contract is marked-to-market daily and the change in market value is recorded by the Fund as unrealized gain or loss. The Fund records realized gains (losses) when the currency

26

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

contract is closed equal to the difference between the value of the currency contract at the time it was opened and the value at the time it was closed.

As of September 30, 2017, the Fund did not have any outstanding foreign currency forward exchange contracts.

Futures — A futures contract is a standardized, exchange-traded agreement to buy or sell a specific quantity of an underlying asset, reference rate or index at a specific price at a specific future time. The value of a futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). A decision as to whether, when and how to use futures contracts involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the derivatives risks discussed above, the prices of futures contracts can be highly volatile, using futures contracts can lower total return, and the potential loss from futures contracts can exceed the Fund's initial investment in such contracts. No assurance can be given that a liquid market will exist for any particular futures contract at any particular time. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with which the Fund has open positions in the futures contract.

Swaps — The Fund may enter into OTC swap contracts or cleared swap transactions. An OTC swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indices, reference rates, currencies or other instruments. Typically swap agreements provide that when the period payment dates for both parties are the same, the payments are made on a net basis (i.e., the two payment streams are netted out, with only the net amount paid by one party to the other). The Fund's obligations or rights under a swap contract entered into on a net basis will generally be equal only to the net amount to be paid or received under the agreement, based on the relative values of the positions held by each party. Cleared swap transactions may help reduce counterparty credit risk. In a cleared swap, the Fund's ultimate counterparty is a clearinghouse rather than a swap dealer, bank or other financial institution. OTC swap agreements are not entered into or traded on exchanges and often there is no central clearing or guaranty function for OTC swaps. These OTC swaps are often subject to credit risk or the risk of default or non-performance by the counterparty. Both OTC and cleared swaps could result in losses if interest rates, foreign currency exchange rates or other factors are not correctly anticipated by the Fund or if the reference index, security or investments do not perform as expected. During the period swap agreements are open,

27

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

payments are received from or made to the clearinghouse or counterparty based upon changes in the value of the contract (variation margin). The Dodd-Frank Wall Street Reform and Consumer Protection Act and related regulatory developments require the clearing and exchange-trading of certain standardized swap transactions. Mandatory exchange-trading and clearing is occurring on a phased-in basis.

The Fund's use of swaps during the period included those based on the credit of an underlying security commonly referred to as "credit default swaps." The Fund may be either the buyer or seller in a credit default swap. Where the Fund is the buyer of a credit default swap contract, it would typically be entitled to receive the par (or other agreed-upon) value of a referenced debt obligation from the counterparty to the contract only in the event of a default or similar event by the issuer of the debt obligation. If no default occurs, the Fund would have paid to the counterparty a periodic stream of payments over the term of the contract and received no benefit from the contract. When the Fund is the seller of a credit default swap contract, it typically receives the stream of payments but is obligated to pay an amount equal to the par (or other agreed-upon) value of a referenced debt obligation upon the default or similar event by the issuer of the referenced debt obligation. The use of credit default swaps could result in losses to the Fund if the Adviser fails to correctly evaluate the creditworthiness of the issuer of the referenced debt obligation.

If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap agreement and take delivery of the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap agreement less the recovery value of the referenced obligation or underlying securities comprising the referenced index. If the Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap agreement and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap agreement less the recovery value of the referenced obligation or underlying securities comprising the referenced index. Recovery values are estimated by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value. The Fund's maximum risk of loss from counterparty risk, either as the protection seller or as the protection buyer, is the fair value of the swap agreement.

Notes to Financial Statements  nSeptember 30, 2017 continued

The current credit rating of each individual issuer is listed in the table following the Fund of Investments and serves as an indicator of the current status of the payment/performance risk of the credit derivative. Alternatively, for credit default swaps on an index of credits, the quoted market prices and current values serve as an indicator of the current status of the payment/performance risk of the credit derivative. Generally, lower credit ratings and increasing market values, in absolute terms, represent a deterioration of the credit and a greater likelihood of an adverse credit event of the issuer.

When the Fund has an unrealized loss on a swap agreement, the Fund has instructed the custodian to pledge cash or liquid securities as collateral with a value approximately equal to the amount of the unrealized loss. Collateral pledges are monitored and subsequently adjusted if and when the swap valuations fluctuate. If applicable, cash collateral is included with "Due from (to) broker" in the Statement of Assets and Liabilities.

Upfront payments paid or received by the Fund will be reflected as an asset or liability, respectively, in the Statement of Assets and Liabilities.

FASB ASC 815, "Derivatives and Hedging" ("ASC 815"), is intended to improve financial reporting about derivative instruments by requiring enhanced disclosures to enable investors to better understand how and why the Fund uses derivative instruments, how these derivative instruments are accounted for and their effects on the Fund's financial position and results of operations.

(b)  Excludes exchange-traded derivatives.

(c)  Absent an event of default or early termination, OTC derivative assets and liabilities are presented gross and not offset in the Statement of Assets and Liabilities.

The Fund typically enters into International Swaps and Derivatives Association, Inc. Master Agreements ("ISDA Master Agreements") or similar master agreements (collectively, "Master Agreements") with its contract counterparties for certain OTC derivatives in order to, among other things, reduce its credit risk to counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund typically may offset with the counterparty certain OTC derivative financial instruments' payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default, termination and/or potential deterioration in the credit quality of the counterparty. Various Master Agreements govern the terms of certain transactions with counterparties,

30

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

including transactions such as swap, forward, repurchase and reverse repurchase agreements. These Master Agreements typically attempt to reduce the counterparty risk associated with such transactions by specifying credit protection mechanisms and providing standardization that improves legal certainty. Cross-termination provisions under Master Agreements typically provide that a default in connection with one transaction between the Fund and a counterparty gives the non-defaulting party the right to terminate any other transactions in place with the defaulting party to create one single net payment due to/due from the defaulting party and may be a feature in certain Master Agreements. In the event the Fund exercises its right to terminate a Master Agreement after a counterparty experiences a termination event as defined in the Master Agreement, the return of collateral with market value in excess of the Fund's net liability may be delayed or denied.

The following tables present derivative financial instruments that are subject to enforceable netting arrangements as of September 30, 2017.

Futures Contracts:
Average monthly original value	$	43,399,757
Swap Agreements:
Average monthly notional amount	$	11,296,800

4. Advisory/Administration Agreements

Pursuant to an Investment Advisory Agreement with the Adviser, the Fund pays an advisory fee, accrued daily and paid monthly, by applying the following annual rates to the Fund: 0.42% to the portion of the average weekly net assets not exceeding $500 million and 0.35% to the portion of the average weekly net assets exceeding $500 million. For the year ended September 30, 2017, the advisory fee rate was equivalent to an annual effective rate of 0.42% of the Fund's average weekly net assets.

The Adviser also serves as the Administrator to the Fund and provides administrative services pursuant to an Administration Agreement for an annual fee, accrued daily and paid monthly, of 0.08% of the Fund's average weekly net assets.

31

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

Under a Sub-Administration Agreement between the Administrator and State Street Bank and Trust Company ("State Street"), State Street provides certain administrative services to the Fund. For such services, the Administrator pays State Street a portion of the fee the Administrator receives from the Fund.

5. Security Transactions and Transactions with Affiliates

The cost of purchases and proceeds from sales of investment securities, excluding short-term investments, for the year ended September 30, 2017, aggregated $71,821,293 and $70,722,207, respectively. Included in the aforementioned are sales of U.S. Government securities of $1,898,405 and there were no purchases of U.S. Government securities.

The Fund has an unfunded noncontributory defined benefit pension plan covering certain independent Directors of the Fund who will have served as independent Directors for at least five years at the time of retirement. Benefits under this plan are based on factors which include years of service and compensation. The Directors voted to close the plan to new participants and eliminate the future benefits growth due to increases to compensation after July 31, 2003. At September 30, 2017, the Fund had an accrued pension liability of $48,831, which is reflected as "Directors' fees" in the Statement of Assets and Liabilities.

The Fund is permitted to purchase and sell securities ("cross-trade") from and to other Morgan Stanley Funds as well as other funds and client accounts for which the Adviser or an affiliate of the Adviser serves as investment adviser, pursuant to procedures approved by the Directors in compliance with Rule 17a-7 under the Act (the "Rule"). Each cross-trade is executed at the current market price in compliance with provisions of the Rule. For the year ended September 30, 2017, the Fund did not engage in any cross-trade transactions.

The Fund has an unfunded Deferred Compensation Plan (the "Compensation Plan"), which allows each independent Director to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Directors. Each eligible Director generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value ("NAV") of the Fund.

6. Capital Stock

As permitted by the Fund's offering prospectus, on December 12, 1995, the Fund commenced a share repurchase program for the purposes of enhancing shareholder value and reducing the discount at

32

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

which the Fund's shares trade from their net asset value. During the year ended September 30, 2017, the Fund did not repurchase any of its shares. Since the inception of the program, the Fund has repurchased 3,237,183 of its shares at an average discount of 8.86% from net asset value per share. The Directors regularly monitor the Fund's share repurchase program as part of their review and consideration of the Fund's premium/discount history. The Fund expects to continue to repurchase its outstanding shares at such time and in such amounts as it believes will further the accomplishment of the foregoing objectives, subject to review by the Directors. You can access information about the monthly share repurchase results through Morgan Stanley Investment Management's website: www.morganstanley.com/im.

7. Custodian Fees

State Street (the "Custodian") serves as Custodian for the Fund in accordance with a Custodian Agreement. The Custodian holds cash, securities, and other assets of the Fund as required by the Act. Custody fees are payable monthly based on assets held in custody, investment purchases and sales activity and account maintenance fees, plus reimbursement for certain out-of-pocket expenses.

8. Dividends

The Fund declared the following dividends from net investment income subsequent to September 30, 2017:

DECLARATION DATE	AMOUNT PER SHARE		RECORD DATE	PAYABLE DATE
October 10, 2017	$	0.0425	October 20, 2017	October 27, 2017
November 7, 2017	$	0.0425	November 17, 2017	November 24, 2017

9. Federal Income Tax Status

It is the Fund's intention to continue to qualify as a regulated investment company and distribute all of its taxable and tax-exempt income. Accordingly, no provision for federal income taxes is required in the financial statements.

The Fund may be subject to taxes imposed by countries in which it invests. Such taxes are generally based on income and/or capital gains earned or repatriated. Taxes are accrued based on net investment income, net realized gains and net unrealized appreciation as such income and/or gains are earned. Taxes may also be based on transactions in foreign currency and are accrued based on the value of investments denominated in such currency.

33

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

FASB ASC 740-10, "Income Taxes—Overall", sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. Management has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. If applicable, the Fund recognizes interest accrued related to unrecognized tax benefits in "Interest Expense" and penalties in "Other Expenses" in the Statement of Operations. The Fund files tax returns with the U.S. Internal Revenue Service, New York and various states. Each of the tax years in the four-year period ended September 30, 2017, remains subject to examination by taxing authorities.

The tax character of distributions paid may differ from the character of distributions shown in the Statements of Changes in Net Assets due to short-term capital gains being treated as ordinary income for tax purposes. The tax character of distributions paid during fiscal years 2017 and 2016 was as follows:

2017 DISTRIBUTIONS PAID FROM:				2016 DISTRIBUTIONS PAID FROM:
ORDINARY INCOME		LONG-TERM CAPITAL GAIN		ORDINARY INCOME		LONG-TERM CAPITAL GAIN
$	6,576,329	$	—	$	6,204,590	$	3,930,717

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations which may differ from GAAP. These book/tax differences are either considered temporary or permanent in nature.

Temporary differences are attributable to differing book and tax treatments for the timing of the recognition of gains (losses) on certain investment transactions and the timing of the deductibility of certain expenses.

Permanent differences, primarily due to differing treatments of gains (losses) related to foreign currency transactions, basis adjustments for swap transactions, paydown adjustments, nondeductible expenses, tax adjustments on debt securities sold by the Fund and a dividend redesignation, resulted in the following reclassifications among the Fund's components of net assets at September 30, 2017:

ACCUMULATED UNDISTRIBUTED NET INVESTMENT INCOME		ACCUMULATED NET REALIZED LOSS		PAID-IN-CAPITAL
$	141,562	$	55,083	$	(196,645	)

34

Morgan Stanley Income Securities Inc.

Notes to Financial Statements  nSeptember 30, 2017 continued

At September 30, 2017, the Fund had no distributable earnings on a tax basis.

At September 30, 2017, the Fund had available for federal income tax purposes unused short-term capital losses of $411,040 that do not have an expiration date. To the extent that capital loss carryforwards are used to offset any future capital gains realized, no capital gains tax liability will be incurred by the Fund for gains realized and not distributed. To the extent that capital gains are offset, such gains will not be distributed to the shareholders. During the year ended September 30, 2017, the Fund utilized capital loss carryforwards for U.S. federal income tax purposes of $2,827,496.

Qualified late year losses are capital losses and specified ordinary losses, including currency losses, incurred after October 31 but within the taxable year that, if elected, are deemed to arise on the first day of the Fund's next taxable year. These also include non-specified ordinary losses incurred after December 31 but within the same taxable year. For the year ended September 30, 2017, the Fund deferred to October 1, 2017 for U.S. federal income tax purposes the following losses:

QUALIFIED LATE YEAR ORDINARY LOSSES		POST-OCTOBER CAPITAL LOSSES
$	6,696	$	—

10. Other

At September 30, 2017, the Fund had record owners of 10% or greater. Investment activities of these shareholders could have a material impact on the Fund. The aggregate percentage of such owners was 24.5%.

11. Accounting Pronouncement

In March 2017, FASB issued an Accounting Standard Update, ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities (the "ASU") which amends the amortization period for certain purchased callable debt securities held at a premium, shortening such period to the earliest call date. The ASU does not require any accounting change for debt securities held at a discount; the discount continues to be amortized to maturity. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. At this time, management is evaluating the implications of these changes on the financial statements.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of
Morgan Stanley Income Securities Inc.

We have audited the accompanying statement of assets and liabilities of Morgan Stanley Income Securities Inc. (the "Fund"), including the portfolio of investments, as of September 30, 2017, 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 years or periods indicated therein. 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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Fund was not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of September 30, 2017, by correspondence with the custodian and others or by other appropriate auditing procedures where replies from others were not received. 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 Morgan Stanley Income Securities Inc. at September 30, 2017, 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 years or periods indicated therein, in conformity with U.S. generally accepted accounting principles.

Investment Advisory Agreement Approval (unaudited)

Nature, Extent and Quality of Services

The Board reviewed and considered the nature and extent of the investment advisory services provided by the Adviser (as defined herein) under the advisory agreement, including portfolio management, investment research and equity and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Adviser under the administration agreement, including accounting, operations, clerical, bookkeeping, compliance, business management and planning, legal services and the provision of supplies, office space and utilities at the Adviser's expense. The Board also considered the Adviser's investment in personnel and infrastructure that benefits the Fund. (The advisory and administration agreements together are referred to as the "Management Agreement.") The Board also considered that the Adviser serves a variety of other investment advisory clients and has experience overseeing service providers. The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as presented to the Board by Broadridge Financial Solutions, Inc. ("Broadridge").

The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the administrative and advisory services to the Fund. The Board determined that the Adviser's portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Fund and supported its decision to approve the Management Agreement.

Performance, Fees and Expenses of the Fund

The Board reviewed the performance, fees and expenses of the Fund compared to its peers, as presented by Broadridge, and to appropriate benchmarks where applicable. The Board discussed with the Adviser the performance goals and the actual results achieved in managing the Fund. When considering a fund's performance, the Board and the Adviser place emphasis on trends and longer-term returns (focusing on one-year, three-year and five-year performance, as of December 31, 2016, or since inception, as applicable). When a fund underperforms its benchmark and/or its peer group average, the Board and the Adviser discuss the causes of such underperformance and, where necessary, they discuss specific changes to investment strategy or investment personnel. The Board noted that the Fund's performance was below its peer group average for the three-year period but better than its peer group average for the one- and five-year periods. The Board discussed with the Adviser the level of the advisory and administration fees (together, the "management fee") for this Fund relative to comparable funds and/or other accounts advised by the Adviser and/or compared to its peers as presented by Broadridge. In addition to the management fee, the Board also reviewed the Fund's total expense ratio. The Board noted that the Fund's management fee and total expense ratio were higher than but close to

38

Morgan Stanley Income Securities Inc.

Investment Advisory Agreement Approval (unaudited) continued

its peer group averages. After discussion, the Board concluded that the Fund's (i) performance was acceptable; and (ii) management fee and total expense ratio were competitive with its peer group averages.

Economies of Scale

The Board considered the size and growth prospects of the Fund and how that relates to the Fund's total expense ratio and particularly the Fund's management fee rate, which includes a breakpoint. In conjunction with its review of the Adviser's profitability, the Board discussed with the Adviser how a change in assets can affect the efficiency or effectiveness of managing the Fund and whether the management fee level is appropriate relative to current and projected asset levels and/or whether the management fee structure reflects economies of scale as asset levels change. The Board considered that, with respect to closed-end funds, the assets are not likely to grow with new sales or grow significantly as a result of capital appreciation. The Board concluded that economies of scale for the Fund were not a factor that needed to be considered at the present time.

Profitability of the Adviser and Affiliates

The Board considered information concerning the costs incurred and profits realized by the Adviser and its affiliates during the last year from their relationship with the Fund and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. The Board has determined that its review of the analysis of the Adviser's expenses and profitability supports its decision to approve the Management Agreement.

Other Benefits of the Relationship

The Board considered other direct and indirect benefits to the Adviser and/or its affiliates derived from their relationship with the Fund and other funds advised by the Adviser. These benefits may include, among other things, fees for trading, distribution and/or shareholder servicing and for transaction processing and reporting platforms used by securities lending agents, and research received by the Adviser generated from commission dollars spent on funds' portfolio trading. The Board reviewed with the Adviser these arrangements and the reasonableness of the Adviser's costs relative to the services performed. The Board has determined that its review of the other benefits received by the Adviser or its affiliates supports its decision to approve the Management Agreement.

Resources of the Adviser and Historical Relationship Between the Fund and the Adviser

The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board also reviewed and considered the historical relationship between the Fund and the Adviser, including the organizational structure of the

39

Morgan Stanley Income Securities Inc.

Investment Advisory Agreement Approval (unaudited) continued

Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Fund's operations and the Board's confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement and that it is beneficial for the Fund to continue its relationship with the Adviser.

Other Factors and Current Trends

The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Fund's Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Fund's business.

General Conclusion

After considering and weighing all of the above factors, with various written materials and verbal information presented by the Adviser, the Board concluded that it would be in the best interest of the Fund and its shareholders to approve renewal of the Management Agreement for another year. In reaching this conclusion the Board did not give particular weight to any single piece of information or factor referenced above. The Board considered these factors and information over the course of the year and in numerous meetings, some of which were in executive session with only the independent Board members and their counsel present. It is possible that individual Board members may have weighed these factors, and the information presented, differently in reaching their individual decisions to approve the Management Agreement.

Investment Policy (unaudited)

Derivatives

The Fund may, but it is not required to, use derivative instruments for a variety of purposes, including hedging, risk management, portfolio management or to earn income. A derivative is a financial instrument whose value is based, in part, on the value of an underlying asset, interest rate, index or financial instrument. Prevailing interest rates and volatility levels, among other things, also affect the value of derivative instruments. A derivative instrument often has risks similar to its underlying asset and may have additional risks, including imperfect correlation between the value of the derivative and the underlying asset, risks of default by the counterparty to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative instrument relates, risks that the transactions may not be liquid and risks arising from margin requirements. The use of derivatives involves risks that are different from, and possibly greater than, the risks associated with other portfolio investments. Derivatives may involve the use of highly specialized instruments that require investment techniques and risk analyses different from those associated with other portfolio investments. In addition, proposed regulatory changes by the Securities and Exchange Commission ("SEC") relating to a mutual fund's use of derivatives could potentially limit or impact the Fund's ability to invest in derivatives and adversely affect the value or performance of the Fund or its derivative investments. Certain derivative transactions may give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss. Leverage associated with derivative transactions may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet earmarking or segregation requirements, pursuant to applicable SEC rules and regulations, or may cause the Fund to be more volatile than if the Fund had not been leveraged. Although the Adviser seeks to use derivatives to further the Fund's investment objectives, there is no assurance that the use of derivatives will achieve this result.

Following is a description of the derivative instruments and techniques that the Fund may use and their associated risks:

Futures. A futures contract is a standardized, exchange-traded agreement to buy or sell a specific quantity of an underlying asset, reference rate or index at a specific price at a specific future time. The value of a futures contract tends to increase or decrease in tandem with the value of the underlying instrument. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. A decision as to whether, when and how to use futures contracts involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the derivatives risks discussed above, the prices of futures contracts can be highly volatile, using futures contracts can lower total return, and the potential loss from futures contracts can exceed the Fund's initial investment in such contracts. No assurance can be given that a liquid market will exist for any particular futures contract at

Morgan Stanley Income Securities Inc.

Investment Policy (unaudited) continued

any particular time. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with which the Fund has open positions in the futures contract.

Options. If the Fund buys an option, it buys a legal contract giving it the right to buy or sell a specific amount of the underlying instrument or futures contract on the underlying instrument at an agreed-upon price typically in exchange for a premium paid by the Fund. If the Fund sells an option, it sells to another person the right to buy from or sell to the Fund a specific amount of the underlying instrument or foreign currency or futures contract on the underlying instrument or foreign currency at an agreed-upon price typically in exchange for a premium received by the Fund. When options are purchased over-the-counter ("OTC"), the Fund bears the risk that the counterparty that wrote the option will be unable or unwilling to perform its obligations under the option contract. Options may also be illiquid and the Fund may have difficulty closing out its position. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well-conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Swaps. The Fund may enter into OTC swap contracts or cleared swap transactions. An OTC swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indices, reference rates, currencies or other instruments. Typically swap agreements provide that when the period payment dates for both parties are the same, the payments are made on a net basis (i.e., the two payment streams are netted out, with only the net amount paid by one party to the other). The Fund's obligations or rights under a swap contract entered into on a net basis will generally be equal only to the net amount to be paid or received under the agreement, based on the relative values of the positions held by each party. Cleared swap transactions may help reduce counterparty credit risk. In a cleared swap, the Fund's ultimate counterparty is a clearinghouse rather than a swap dealer, bank or other financial institution. OTC swap agreements are not entered into or traded on exchanges and often there is no central clearing or guaranty function for OTC swaps. These OTC swaps are often subject to credit risk or the risk of default or non-performance by the counterparty. Both OTC and cleared swaps could result in losses if interest rates, foreign currency exchange rates or other factors are not correctly anticipated by the Fund or if the reference index, security or investments do not perform as expected. The Fund enters into credit default, interest rate and other forms of swap agreements to manage exposure to credit and interest rate risks. The Fund's use of swaps may include those based on the credit of an underlying security, commonly referred to as "credit default swaps". The Fund may be either the buyer or the seller in a credit default swap. Where the Fund is the buyer of a credit default swap contract, it would typically be entitled to receive the par (or other agreed-upon) value of a referenced debt obligation from the counterparty to the contract only in the event of a default or similar event of the issuer of the referenced debt obligation. If no default occurs, the Fund would have paid to the counterparty a periodic stream of payments over the term of the contract and received no

44

benefit from the contract. When the Fund is the seller of a credit default swap contract, typically it receives the stream of payments but is obligated to pay an amount equal to the par (or other agreed-upon) value of a referenced debt obligation upon the default or similar event by the issuer of the debt obligation. The Dodd-Frank Wall Street Reform and Consumer Protection Act and related regulatory developments require the clearing and exchange-trading of certain standardized swap transactions. Mandatory exchange-trading and clearing is occurring on a phased-in basis.

Foreign Currency Forward Exchange Contracts. In connection with its investments in foreign securities, the Fund also may enter into contracts with banks, brokers or dealers to purchase or sell securities or foreign currencies at a future date. A foreign currency forward exchange contract ("currency contract") is a negotiated agreement between the contracting parties to exchange a specified amount of currency at a specified future time at a specified rate. The rate can be higher or lower than the spot rate between the currencies that are the subject of the contract. The Fund may also invest in non-deliverable foreign currency forward exchange contracts ("NDFs"). NDFs are similar to other foreign currency forward exchange contracts, but do not require or permit physical delivery of currency upon settlement. Instead, settlement is made in cash based on the difference between the contracted exchange rate and the spot foreign exchange rate at settlement. Currency contracts may be used to protect against uncertainty in the level of future foreign currency exchange rates or to gain or modify exposure to a particular currency. In addition, the Fund may use cross currency hedging or proxy hedging with respect to currencies in which the Fund has or expects to have portfolio or currency exposure. Cross currency and proxy hedges involve the sale of one currency against the positive exposure to a different currency and may be used for hedging purposes or to establish an active exposure to the exchange rate between any two currencies. To the extent hedged by the use of currency contracts, the precise matching of the currency contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. Furthermore, such transactions may reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken. There is additional risk to the extent that currency contracts create exposure to currencies in which the Fund's securities are not denominated. Unanticipated changes in currency prices may result in poorer overall performance for the Fund than if it had not entered into such contracts. The use of currency contracts involves the risk of loss from the insolvency or bankruptcy of the counterparty to the contract or the failure of the counterparty to make payments or otherwise comply with the terms of the contract.

Mortgage Securities

Mortgage securities derive their value from the value of underlying mortgages. Mortgage securities are subject to the risks of price movements in response to changing interest rates and the level of

45

Morgan Stanley Income Securities Inc.

Investment Policy (unaudited) continued

prepayments made by borrowers of the underlying mortgages. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of a mortgage-backed security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payment on their mortgages.

Collateralized Mortgage Obligations ("CMOs") are debt obligations collateralized by mortgage loans or mortgage pass-through securities (collectively "Mortgage Assets"). Payments of principal and interest on the Mortgage Assets and any reinvestment income are used to make payments on the CMOs. CMOs are issued in multiple classes. Each class has a fixed or floating coupon rate and a stated maturity or final distribution date. The principal and interest on the Mortgage Assets may be allocated among the classes in a number of different ways including "interest only ("IO")" classes and "inverse IO" classes. Certain classes will, as a result of the allocation, have more predictable cash flows than others. As a general matter, the more predictable the cash flow, the lower the yield relative to other Mortgage Assets. The less predictable the cash flow, the higher the yield and the greater the risk. The Fund may invest in any class of CMOs. The general goal in allocating cash flows on Mortgage Assets to the various classes of a CMO is to create certain tranches on which the expected cash flows have a higher degree of predictability than do the underlying Mortgage Assets. As a general matter, the more predictable the cash flow is on a particular CMO tranche, the lower the anticipated yield on that tranche at the time of issue will be relative to the prevailing market yields on the Mortgage Assets. As part of the process of creating more predictable cash flows on certain tranches of a CMO, one or more tranches generally must be created that absorb most of the changes in the cash flows on the underlying Mortgage Assets. The yields on these tranches are generally higher than prevailing market yields on other mortgage-related securities with similar average lives. Principal prepayments on the underlying Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates.

Because of the uncertainty of the cash flows on these tranches, the market prices and yields of these tranches are more volatile and may increase or decrease in value substantially with changes in interest rates and/or the rates of prepayment. Due to the possibility that prepayments (on home mortgages and other collateral) will alter the cash flow on CMOs, it is not possible to determine in advance the final maturity date or average life. Faster prepayment will shorten the average life and slower prepayments will lengthen it. In addition, if the collateral securing CMOs or any third-party guarantees is insufficient to make payments, the Fund could sustain a loss.

Commercial Mortgage-Backed Securities ("CMBS") are generally multi-class or pass-through securities backed by a mortgage loan or a pool of mortgage loans secured by commercial property, such as industrial and warehouse properties, office buildings, retail space and shopping malls, multi-family properties and cooperative apartments. The commercial mortgage loans that underlie CMBS are generally not amortizing or not fully amortizing. That is, at their maturity date, repayment of their

46

Morgan Stanley Income Securities Inc.

Investment Policy (unaudited) continued

remaining principal balance or "balloon" is due and is repaid through the attainment of an additional loan or sale of the property. An extension of a final payment on commercial mortgages will increase the average life of the CMBS, generally resulting in a lower yield for discount bonds and a higher yield for premium bonds. CMBS are subject to credit risk and prepayment risk. Although prepayment risk is present, it is of a lesser degree in the CMBS than in the residential mortgage market; commercial real estate property loans often contain provisions which substantially reduce the likelihood that such securities will be prepaid (e.g., significant prepayment penalties on loans and, in some cases, prohibition on principal payments for several years following origination).

Stripped Mortgage-Backed Securities ("SMBSs") are derivative multi-class mortgage securities. SMBSs may be issued by agencies or instrumentalities of the U.S. government, or by private originators. A common type of SMBS will have one class receiving some of the interest and most of the principal from the Mortgage Assets, while the other class receives most of the interest and the remainder of the principal. In the most extreme case, 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). Investments in each class of SMBS are extremely sensitive to changes in interest rates. IOs tend to decrease in value substantially if interest rates decline and prepayment rates become more rapid. POs tend to decrease in value substantially if interest rates increase and the rate of prepayment decreases. If the Fund invests in SMBSs and interest rates move in a manner not anticipated by Fund management, it is possible that the Fund could lose all or substantially all of its investment.

Defensive Investing

The Fund may take temporary "defensive" positions in attempting to respond to adverse market, economic, political or other conditions. When the Fund is in a defensive position, the Fund may invest any amount of its assets in cash, cash equivalents or other fixed-income securities in a defensive posture that may be inconsistent with the Fund's principal investment strategies when the Adviser believes it is advisable to do so.

Although taking a defensive posture is designed to protect the Fund from an anticipated market downturn, it could have the effect of reducing the benefit from any upswing in the market. When the Fund takes a defensive position, it may not achieve its investment objective.

Special Risks Related to Cyber Security

The Fund and its service providers are susceptible to cyber security risks that include, among other things, theft, unauthorized monitoring, release, misuse, loss, destruction or corruption of confidential and highly restricted data; denial of service attacks; unauthorized access to relevant systems; compromises to networks or devices that the Fund and its service providers use to service the Fund's operations; or operational disruption or failures in the physical infrastructure or operating systems that support the

47

Morgan Stanley Income Securities Inc.

Investment Policy (unaudited) continued

Fund and its service providers. Cyber attacks against or security breakdowns of the Fund or its service providers may adversely impact the Fund and its shareholders, potentially resulting in, among other things, financial losses; the inability of Fund shareholders to transact business and the Fund to process transactions; inability to calculate the Fund's NAV; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs; and/or additional compliance costs. The Fund may incur additional costs for cyber security risk management and remediation purposes. In addition, cyber security risks may also impact issuers of securities in which the Fund invests, which may cause the Fund's investment in such issuers to lose value. There can be no assurance that the Fund or its service providers will not suffer losses relating to cyber attacks or other information security breaches in the future.

Foreign and Emerging Market Securities

Investing in the securities of foreign issuers, particularly those located in emerging market or developing countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. The value of the Fund's shares may vary widely in response to political and economic factors affecting companies in foreign countries. These same events will not necessarily have an effect on the U.S. economy or similar issuers located in the United States. In addition, investments in certain foreign markets that have historically been considered stable may become more volatile and subject to increased risk due to ongoing developments and changing conditions in such markets. Moreover, the growing interconnectivity of global economies and financial markets has increased the probability that adverse developments and conditions in one country or region will affect the stability of economies and financial markets in other countries or regions.

Certain foreign markets may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments, the imposition of economic sanctions against a particular country or countries, organizations, entities and/or individuals, changes in international trading patterns, trade barriers, and other protectionist or retaliatory measures. Economic sanctions could, among other things, effectively restrict or eliminate the Fund's ability to purchase or sell securities or groups of securities for a substantial period of time, and may make the Fund's investments in such securities harder to value. International trade barriers or economic sanctions against foreign countries, organizations, entities and/or individuals, may adversely affect the Fund's foreign holdings or exposures. Investments in foreign markets may also be adversely affected by governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. Governmental actions can have a significant effect on the economic conditions in foreign countries, which also may adversely affect the value and liquidity of the Fund's investments. For example, the governments of certain countries may prohibit or impose substantial restrictions on foreign investing in their capital markets or in certain sectors or industries. In addition, a foreign government may limit or cause delay in the convertibility or repatriation of its currency which would adversely affect the U.S.

48

Morgan Stanley Income Securities Inc.

Investment Policy (unaudited) continued

dollar value and/or liquidity of investments denominated in that currency. Any of these actions could severely affect security prices, impair the Fund's ability to purchase or sell foreign securities or transfer the Fund's assets back into the United States, or otherwise adversely affect the Fund's operations. Certain foreign investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market turmoil. Certain foreign investments may become illiquid when, for instance, there are few, if any, interested buyers and sellers or when dealers are unwilling to make a market for certain securities. When the Fund holds illiquid investments, its portfolio may be harder to value.

Determination of NAV

The Fund determines the NAV per share as of the close of the NYSE (normally 4:00p.m. Eastern time) on each day that the NYSE is open for business. Shares generally will not be priced on days that the NYSE is closed, although shares may be priced on such days if the Securities Industry and Financial Markets Association ("SIFMA") recommends that the bond markets remain open for all or part of the day. On any business day when SIFMA recommends that the bond markets close early, the Fund reserves the right to price its shares at or prior to the SIFMA recommended closing time. If the NYSE is closed due to inclement weather, technology problems or any other reason on a day it would normally be open for business, or the NYSE has an unscheduled early closing on a day it has opened for business, the Fund reserves the right to treat such day as a business day and calculate its NAV as of the normally scheduled close of regular trading on the NYSE for that day, so long as the Adviser believes there generally remains an adequate market to obtain reliable and accurate market quotations. The Fund may elect to price its shares on days when the NYSE is closed but the primary securities markets on which the Fund's securities trade remain open.

Dividend Reinvestment Plan (unaudited)

The dividend reinvestment plan (the Plan) offers you a prompt and simple way to reinvest your dividends and capital gains distributions (Distributions) into additional shares of the Fund. Under the Plan, the money you earn from Distributions will be reinvested automatically in more shares of the Fund, allowing you to potentially increase your investment over time.

Plan benefits

•  Add to your account
You may increase your shares in the Fund easily and automatically with the Plan.

•  Low transaction costs
Transaction costs are low because the new shares are bought in blocks and the brokerage commission is shared among all participants.

•  Convenience
You will receive a detailed account statement from Computershare Trust Company, N.A., (the Agent) which administers the Plan. The statement shows your total Distributions, dates of investment, shares acquired, and price per share, as well as the total number of shares in your reinvestment account. You can also access your account at morganstanley.com/im/cef.

•  Safekeeping
The Agent will hold the shares it has acquired for you in safekeeping.

How to participate in the Plan

If you own shares in your own name, you can participate directly in the Plan. If your shares are held in "street name" — in the name of your brokerage firm, bank, or other financial institution — you must instruct that entity to participate on your behalf. If they are unable to participate on your behalf, you may request that they reregister your shares in your own name so that you may enroll in the Plan.

If you choose to participate in the Plan, whenever the Fund declares a distribution, it will be invested in additional shares of the Fund that are purchased in the open market.

How to enroll

To enroll in the Plan, please read the Terms and Conditions in the Plan brochure. You can obtain a copy of the Plan Brochure and enroll in the Plan by visiting morganstanley.com/im/cef, calling toll-free (800) 231-2608 or notifying us in writing at Morgan Stanley Closed-End Funds, Computershare Trust Company, N.A., P.O. Box 30170, College Station, Texas 77842. Please include the Fund name and account number and ensure that all shareholders listed on the account sign the written instructions. Your participation in the Plan will begin with the next Distribution payable after the Agent receives your authorization, as long as they receive it before the "record date," which is generally one week before the

50

Morgan Stanley Income Securities Inc.

Dividend Reinvestment Plan (unaudited) continued

dividend is paid. If your authorization arrives after such record date, your participation in the Plan will begin with the following Distribution.

Costs of the Plan

There is no direct charge to you for reinvesting dividends and capital gains distributions because the Plan's fees are paid by the Fund. However, when applicable, you will pay your portion of any brokerage commissions incurred when the new shares are purchased on the open market. These brokerage commissions are typically less than the standard brokerage charges for individual transactions, because shares are purchased for all participants in blocks, resulting in lower commissions for each individual participant. Any brokerage commissions or service fees are averaged into the purchase price.

Tax implications

The automatic reinvestment of dividends and capital gains distributions does not relieve you of any income tax that may be due on dividends or capital gains distributions. You will receive tax information annually to help you prepare your federal and state income tax returns.

APPENDIX A

AUDIT COMMITTEE

AUDIT AND NON-AUDIT SERVICES

PRE-APPROVAL POLICY AND PROCEDURES

OF THE

MORGAN STANLEY RETAIL AND INSTITUTIONAL FUNDS

AS ADOPTED AND AMENDED JULY 23, 2004,1

1.Statement of Principles

The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor’s independence from the Fund.

The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee’s administration of the engagement of the independent auditor.  The SEC’s rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid.  Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee (“general pre-approval”); or require the specific pre-approval of the Audit Committee or its delegate (“specific pre-approval”).  The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors.  As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors.  Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee.

The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee.  The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise.  The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee.  The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations.

1This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the “Policy”), adopted as of the date above, supersedes and replaces all prior versions that may have been adopted from time to time.

The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities.  It does not delegate the Audit Committee’s responsibilities to pre-approve services performed by the Independent Auditors to management.

The Fund’s Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors’ independence.

2.Delegation

As provided in the Act and the SEC’s rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members.  The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

3.Audit Services

The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee.  Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund’s financial statements.  These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit.  The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items.

In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide.  Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings.

The Audit Committee has pre-approved the Audit services in Appendix B.1.  All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

4.Audit-related Services

Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund’s financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors.  Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC’s rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services.  Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters not classified as “Audit services”; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory

reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR.

The Audit Committee has pre-approved the Audit-related services in Appendix B.2.  All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

5.Tax Services

The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor’s independence, and the SEC has stated that the Independent Auditors may provide such services.

Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3.  All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

6.All Other Services

The Audit Committee believes, based on the SEC’s rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted.  Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC’s rules on auditor independence.

The Audit Committee has pre-approved the All Other services in Appendix B.4.  Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

7.Pre-Approval Fee Levels or Budgeted Amounts

Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee.  Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee.  The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services.

8.Procedures

All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund’s Chief Financial Officer and must include a detailed description of the services to be rendered.  The Fund’s Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee.  The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors.  Requests or applications to provide services that require specific approval by the

Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund’s Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC’s rules on auditor independence.

The Audit Committee has designated the Fund’s Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy.  The Fund’s Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring.  Both the Fund’s Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund’s Chief Financial Officer or any member of management.

9.Additional Requirements

The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor’s independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence.

10.Covered Entities

Covered Entities include the Fund’s investment adviser(s) and any entity controlling, controlled by or under common control with the Fund’s investment adviser(s) that provides ongoing services to the Fund(s).  Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund’s audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund.  This list of Covered Entities would include:

(f)     Not applicable.

(g)    See table above.

Item 8. Portfolio Managers of Closed-End Management Investment Companies

Morgan Stanley Income Securities Inc.

FUND MANAGEMENT

As of the date of this report, the Fund is managed by members of the Taxable Fixed Income team. The team consists of portfolio managers and analysts. Current members of the team jointly and primarily responsible for the day-to-day management of the Fund’s portfolio are Christian G. Roth, Managing Director of the Adviser, Joseph Mehlman, Executive Director of the Adviser and Mikhael Breiterman-Loader, Vice President of the Adviser.

Mr. Roth has been associated with the Adviser or its investment management affiliates in an investment management capacity since 1991 and began managing the Fund in February 2009.  Mr. Mehlman has been associated with the Adviser in an investment management capacity since 2002 and began managing the Fund in November 2008.  Mr. Breiterman-Loader has been associated with the Adviser in an investment management capacity since 2009 and began managing the Fund in May 2015.

OTHER ACCOUNTS MANAGED BY THE PORTFOLIO MANAGER

The following information is as of September 30, 2017:

Mr. Roth managed 8 other registered investment companies with a total of approximately $1.02 billion in assets; 32 pooled investment vehicles other than registered investment companies with a total of approximately $6.1 billion in assets; and 52 other accounts (which include separate accounts managed under certain “wrap fee” programs) with a total of approximately $16.6 billion in assets.

Mr. Mehlman managed 4 other registered investment companies with a total of approximately $669.6 million in assets; 25 pooled investment vehicles other than registered investment companies with a total of approximately $5.7 billion in assets; and 43 other accounts (which include separate accounts managed under certain “wrap fee” programs) with a total of approximately $11.8 billion in assets.

Mr. Breiterman-Loader managed 2 other registered investment companies with a total of approximately $147.9 million in assets; 7 pooled investment vehicles other than registered investment companies with a total of approximately $825.6 million in assets; and 10 other accounts (which include separate accounts managed under certain “wrap fee” programs) with a total of approximately $1.9 billion in assets.

Because the portfolio managers manages assets for other investment companies, pooled investment vehicles and/or other accounts (including institutional clients, pension plans and certain high net worth individuals), there may be an incentive to favor one client over another resulting in conflicts of interest. For instance, the Adviser may receive fees from certain accounts that are higher than the fee it receives from the Fund, or it may receive a performance-based fee on certain accounts. In those instances, the portfolio manager may have an incentive to favor the higher and/or performance-based fee accounts over the Fund.  In addition, a conflict of interest could exist to the extent the Adviser has proprietary investments in certain accounts, where portfolio managers have personal investments in certain accounts or when certain accounts are investment options in the Adviser’s employee benefits and/or deferred compensation plans.  The portfolio managers may have an incentive to favor these accounts over others.  If the Adviser manages accounts that engage in short sales of securities of the type in which the Fund invests, the Adviser could be seen as harming the performance of the Fund for the benefit of the accounts engaging in short sales if the short sales cause the market value of the securities to fall.  The Adviser has adopted trade allocation and other policies and procedures that it believes are reasonably designed to address these and other conflicts of interest.

Portfolio Manager Compensation Structure

Morgan Stanley’s compensation structure is based on a total reward system of base salary and Incentive Compensation which is paid partially as a cash bonus and partially as mandatory deferred compensation.  Deferred compensation may be granted as deferred cash under the Adviser’s Investment Management Alignment Plan (“IMAP”), as an equity-based awards or it may be granted under other plans as determined annually by Morgan Stanley’s Compensation, Management Development and Succession Committee subject to vesting and other conditions.

Base salary compensation. Generally, portfolio managers receive base salary compensation based on the level of their position with the Adviser.

Incentive compensation. In addition to base compensation, portfolio managers may receive discretionary year-end compensation.

Incentive compensation may include:

· Cash Bonus.

· Deferred Compensation:

·A mandatory program that defers a portion of incentive compensation into restricted stock units or other awards based on Morgan Stanley common stock or other plans that are subject to vesting and other conditions.

·IMAP is a mandatory program that defers a portion of incentive compensation and notionally invests it in designated funds advised by the Adviser or its affiliates. The award is subject to vesting and other conditions. Portfolio managers must notionally invest a minimum of 25% to a maximum of 100% of their IMAP deferral account into a combination of the designated funds they manage that are included in the IMAP fund menu, which may or may not include one of the Portfolios.

All deferred compensation awards are subject to clawback provisions where awards can be cancelled, in whole or in part, if an employee takes any action, or omits to take any action which; causes a restatement of Morgan Stanley’s consolidated financial results; constitutes a violation by the portfolio manager of Morgan Stanley’s Global Risk Management Principles, Policies and Standards; or constitutes violation of internal risk and control policies involving a subsequent loss.

Several factors determine discretionary compensation, which can vary by portfolio management team and circumstances. These factors include:

· Revenues generated by the investment companies, pooled investment vehicles and other accounts managed by the portfolio manager.

· The investment performance of the funds/accounts managed by the portfolio manager.

· Contribution to the business objectives of the Adviser.

· The dollar amount of assets managed by the portfolio manager.

· Market compensation survey research by independent third parties.

· Other qualitative factors, such as contributions to client objectives.

· Performance of Morgan Stanley and Morgan Stanley Investment Management, and the overall performance of the investment team(s) of which the portfolio manager is a member.
