Performance

For the year ended December 31, 2012, the Morgan Stanley Emerging Markets Debt Fund, Inc. (the "Fund") had total returns of 19.51%, based on net asset value, and 21.04% based on market value per share (including reinvestment of distributions), compared to its benchmark, the J.P. Morgan Emerging Markets Bond Global Index (the "Index")*, which returned 18.54%. On December 31, 2012, the closing price of the Fund's shares on the New York Stock Exchange was $11.95, representing an 8.6% discount to the Fund's net asset value per share. Past performance is no guarantee of future results. Please keep in mind that high double-digit returns are highly unusual and cannot be sustained.

Factors Affecting Performance

•  Global risk assets, including emerging markets (EM) asset classes, strengthened in the first two months of the year due to signs of a global recovery, before slightly weakening in March, as U.S. economic optimism could not overcome fears about global growth, led by softer-than-expected economic data out of China.

•  In the second quarter of 2012, risk sentiment trended lower due to Greek political and debt-sustainability concerns, signs of distress out of the euro area periphery, stagnant U.S. jobs growth, and softer Chinese economic data. The benchmark 10-year U.S. Treasury registered record low yields at the end of May amid heightened global growth fears. However, global risk assets recovered partially in June as risk sentiment modestly improved.

•  Global risk assets continued their ascent in the third quarter as decisive developed market policy measures reduced the "tail" risks (that is, an extreme level of risk) for investors, particularly in the euro area, and fostered a more supportive macro environment, despite more moderation in U.S. and China's growth. Emerging market currencies strengthened markedly versus the U.S. dollar as the European Central Bank's (ECB) aggressive rhetoric and bond-buying program as well as Federal Reserve policy action helped buoy higher-yielding assets. Soybean, grain, and corn prices hit record highs due to damaged agricultural harvests, while crude oil stayed at high levels.

•  Despite drawn-out U.S. fiscal cliff negotiations and anti-austerity labor protests sweeping across Europe, risk assets ended the fourth quarter stronger as manufacturing activity in China expanded, U.S. presidential election uncertainty abated, and the likelihood of a Greek euro exit fell, prompting investors to take a more optimistic tone toward global growth.

•  New issuance activity hit record numbers in 2012, as EM sovereign supply reached $82 billion and a record $329 billion by corporate issuers, bringing the combined total to $411 billion, according to our research.

•  In 2012, emerging market dedicated bond funds tracked by EPFR Global saw net inflows of $38.85 billion, up from $7.9 billion accumulated in 2011, according to weekly data. By currency, while around 60% of inflows went into hard currency funds, local currency inflows picked up pace in the last two months of the year and saw relatively larger flows. EM equity fund inflows totaled $49.4 billion in 2012.

Letter to Stockholders (unaudited) (cont'd)

•  Over the course of the year, the risk premium on the Index tightened 160 basis points to 266 basis points above U.S. Treasuries.

•  The Fund benefited from overweight exposure to Brazil, Kazakhstan, Mexico, Russia, and Venezuela. Brazil benefited from signs of a recovery in growth and the recent increase in global agricultural prices, notably soybean, caused by droughts in the U.S. In Kazakhstan, Russia and Venezuela, rising oil prices acted as a support. Additionally, in Venezuela, investors speculated that political transition may ensue given the fragile state of market-unfriendly President Hugo Chavez's health. In addition, exposure to Peruvian local markets as well as Mexican and Russian corporates helped boost relative performance.

•  Conversely, underweight exposure to Hungary, Philippines, Poland, Turkey, and Ukraine detracted from relative returns. Hungary outperformed due to investor optimism over the country's ability to meet its debt obligations, despite the lack of progress on an International Monetary Fund/European Union financing agreement. In the Philippines, resilient growth, strong capital inflows, and positive ratings momentum were supportive. Despite slowing growth, Poland and high-beta Ukraine outperformed due to euro-optimism. Turkey benefited from relatively strong growth when compared to its neighbors, export growth from countries outside the slower growing euro zone, and improvement in its current account deficit.

Management Strategies

•  We expect the global economy to exhibit varying degrees of economic recovery in 2013. Global growth has moderated, but we still expect emerging market growth rates to outpace growth rates in developed markets, where growth could likely remain below potential. We believe that this growth differential could remain well into 2013. U.S. issues remain prominent with the fiscal threat representing a serious impediment to the timing of a global growth rebound, while the uncertainty around developments in Europe and, to a lesser extent, China still remain. We anticipate that the emerging markets could from time to time come under pressure until there is some resolution to fiscal issues in Europe and the U.S.

•  Tail risks for investors, particularly those associated with a disorderly sovereign breakup in Europe, appear to have been reduced. However, market direction may likely closely mirror the ongoing issues in Europe and the pace of economic activity in the U.S. and China. Policy easing by core developed market central banks could support commodity prices, capital inflows into emerging countries, and demand for higher-yielding assets.

•  Despite challenges ahead from an uncertain global environment, we remain positive on emerging markets debt prospects. There was a shift in 2012 toward more of an easing bias among emerging economies; however, recent food and energy inflation pressures suggest that policy easing in emerging markets may be put on hold. Nevertheless, most EM countries still appear to have scope for policy stimulus should global growth weaken further. We believe that EM central banks may continue to adopt policies aimed at limiting local currency appreciation, but may not be able to reverse the longer-term appreciation trend in their currencies.

•  By region, we see better potential growth prospects in Latin America, which has shown relative resilience to global factors, and where we are overweight countries with strong and improving fundamentals. We are underweight the euro area as we remain concerned about European bank deleveraging and Europe's debt crisis, particularly among countries where dependency on the euro zone is high. In Asia, growth has held up relatively well, but we believe that many credits are fairly priced and offer lower carry relative to fundamentals. In the Middle East and North Africa, geopolitical risks remain, creating possible spillovers into neighboring countries.**

Arthur Lev

Notes to Financial Statements

Morgan Stanley Emerging Markets Debt Fund, Inc. (the "Fund") was incorporated in Maryland on May 6, 1993, and is registered as a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the "Act"). The Fund's primary investment objective is to produce high current income and as a secondary objective, to seek capital appreciation, through investments primarily in debt securities of government and government-related issuers located in emerging countries, of entities organized to restructure outstanding debt of such issuers and debt securities of corporate issuers in or organized under the laws of emerging countries. To the extent that the Fund invests in derivative instruments that Morgan Stanley Investment Management Inc. (the "Adviser"), believes have economic characteristics similar to debt securities of government and government-related issuers located in emerging market countries and of entities organized to restructure outstanding debt of such issuers, such investments will be counted for purposes of the Fund's policy in the previous sentence. To the extent the Fund makes such investments, the Fund will be subject to the risks of such derivative instruments as described herein.

A.  Significant Accounting Policies: The following significant accounting policies are in conformity with U.S. generally accepted accounting principles ("GAAP"). Such policies are consistently followed by the Fund in the preparation of its financial statements. GAAP may require management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results may differ from those estimates.

1.  Security Valuation: Bonds and other fixed income securities may be valued according to the broadest and most representative market. In addition, bonds and other fixed income securities may be valued on the basis of prices provided by a pricing service. The prices provided by a pricing service take into account broker-dealer market price quotations for institutional size trading in similar groups of

securities, security quality, maturity, coupon and other security characteristics as well as any developments related to the specific securities. Securities listed on a foreign exchange are valued at their closing price, except as noted below. Unlisted securities and listed securities not traded on the valuation date for which market quotations are readily available are valued at the mean between the last reported bid and ask prices. Equity securities listed on a U.S. exchange are valued at the latest quoted sales price on the valuation date. Equity securities listed or traded on NASDAQ, for which market quotations are available, are valued at the NASDAQ Official Closing Price. Short-term debt securities purchased with remaining maturities of 60 days or less are valued at amortized cost, unless the Fund's Board of Directors (the "Directors") determines such valuation does not reflect the securities' fair value, in which case these securities will be valued at their fair value as determined in good faith under procedures adopted by the Directors.

  Under procedures approved by the Directors, the Adviser has formed a Valuation Committee. The Valuation Committee provides administration and oversight of the Fund's valuation policies and procedures, which are reviewed at least annually by the Directors. Among other things, 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

Morgan Stanley Emerging Markets Debt Fund, Inc.

December 31, 2012

Notes to Financial Statements (cont'd)

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.

  Most foreign markets close before the New York Stock Exchange ("NYSE"). Occasionally, developments that could affect the closing prices of securities and other assets may occur between the times at which valuations of such securities are determined (that is, close of the foreign market on which the securities trade) and the close of business on the NYSE. If these developments are expected to materially affect the value of the securities, the valuations may be adjusted to reflect the estimated fair value as of the close of the NYSE, as determined in good faith under procedures established by the Directors.

2.   Fair Value Measurement: Financial Accounting Standards Board ("FASB") Accounting Standards Codification^TM ("ASC") 820, "Fair Value Measurements and Disclosures" ("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.

Morgan Stanley Emerging Markets Debt Fund, Inc.

December 31, 2012

Notes to Financial Statements (cont'd)

The following is a summary of the inputs used to value the Fund's investments as of December 31, 2012.

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 December 31, 2012, the Fund did not have any investments transfer between investment levels.

3.  Reverse Repurchase Agreements: The Fund entered into reverse repurchase agreements with institutions that the Adviser has determined are creditworthy. Under a reverse repurchase agreement, the Fund sells securities and agrees to repurchase them at a mutually agreed upon date

and price. Reverse repurchase agreements involve the risk that the market value of the securities purchased with the proceeds from the sale of securities received by the Fund may decline below the price of the securities the Fund is obligated to repurchase. Reverse repurchase agreements also involve credit risk with the counterparty to the extent that the value of securities subject to repurchase exceed the Fund's liability under the reverse repurchase agreement. Securities subject to repurchase under reverse repurchase agreements, if any, are designated as such in the Portfolio of Investments.

  At December 31, 2012, the Fund had a reverse repurchase agreement outstanding with UBS as follows:

  The weighted average weekly balance of reverse repurchase agreements outstanding during the year ended December 31, 2012 was approximately $1,751,000 at a weighted average weekly interest rate of 0.00%.

4.  Foreign Currency Translation: The books and records of the Fund are maintained in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean of the bid and ask prices of such currencies against U.S. dollars last quoted by a major bank 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.

Morgan Stanley Emerging Markets Debt Fund, Inc.

December 31, 2012

Notes to Financial Statements (cont'd)

  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 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) on the Statement of Assets and Liabilities. The change in unrealized currency gains (losses) for the period is reflected in the Statement of Operations.

  A significant portion of the Fund's net assets consist of securities of issuers located in emerging markets, which are

denominated in foreign currencies. Such securities may be concentrated in a limited number of countries and regions and may vary throughout the year. Changes in currency exchange rates will affect the value of and investment income from foreign currency denominated securities. Emerging market securities are often subject to greater price volatility, limited capitalization and liquidity, and higher rates of inflation than U.S. securities. In addition, emerging market issuers may be subject to substantial governmental involvement in the economy and greater social, economic and political uncertainty.

5.  Derivatives: The Fund may, but 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 on the value of an underlying asset, interest rate, index or financial instrument. 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 they relate, and risks that the transactions may not be liquid. 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.

Morgan Stanley Emerging Markets Debt Fund, Inc.

December 31, 2012

Notes to Financial Statements (cont'd)

  Certain derivative transactions may give rise to a form of leverage. Leverage magnifies the potential for gain and risk for 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:

  Futures: A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument 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 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 can be highly volatile, using futures can lower total return, and the potential loss from futures can exceed the Fund's initial investment in such contracts.

  Foreign Currency Exchange Contracts: In connection with its investments in foreign securities, the Fund also entered into contracts with banks, brokers or dealers to purchase or sell securities or foreign currencies at a future date. A foreign currency exchange contract ("currency contracts") is a negotiated agreement between two parties to exchange specified amounts of two or more currencies at a specified future time at a specified rate. The rate specified by the currency contract 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. Hedging the Fund's currency risks involves the risk of mismatching the Fund's objectives under a currency contract with the value of securities denominated in a particular currency. Furthermore, such transactions 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 an additional risk to the effect 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 currency 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 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.

Notes to Financial Statements (cont'd)

  FASB ASC 815, "Derivatives and Hedging: Overall" ("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.

  The following table sets forth the fair value of the Fund's derivative contracts by primary risk exposure as of December 31, 2012.

  The following tables set forth by primary risk exposure the Fund's realized gains (losses) and change in unrealized appreciation (depreciation) by type of derivative contract for the year ended December 31, 2012 in accordance with ASC 815.

  For the year ended December 31, 2012, the average monthly principal amount of foreign currency exchange

contracts was approximately $2,789,000 and the average monthly original value of futures contracts was approximately $3,670,000.

6.   Security Lending: The Fund lends securities to qualified financial institutions, such as broker-dealers, to earn additional income. Any increase or decrease in the fair value of the securities loaned that might occur and any interest earned or dividends declared on those securities during the term of the loan would remain in the Fund. The Fund would receive cash or securities as collateral in an amount equal to or exceeding 100% of the current fair value of the loaned securities. The collateral is marked-to-market daily, by the securities lending agent, to ensure that a minimum of 100% collateral coverage is maintained.

  Based on pre-established guidelines, the securities lending agent invests any cash collateral that is received in an affiliated money market portfolio and repurchase agreements. Securities lending income is generated from the earnings on the invested collateral and borrowing fees, less any rebates owed to the borrowers and compensation to the lending agent, and is recorded as "Income from Securities Loaned — Net" in the Fund's Statement of Operations. Risks in securities lending transactions are that a borrower may not provide additional collateral when required or return the securities when due, and that the value of the short-term investments will be less than the amount of cash collateral plus any rebate that is required to be returned to the borrower.

  The value of loaned securities and related collateral outstanding at December 31, 2012 were approximately $20,974,000 and $21,450,000, respectively. The Fund received cash collateral of approximately $21,450,000, of which, approximately $20,712,000 was subsequently invested in Repurchase Agreements and Morgan Stanley Institutional Liquidity Funds as reported in the Portfolio of Investments. At December 31, 2012, there was uninvested

Morgan Stanley Emerging Markets Debt Fund, Inc.

December 31, 2012

Notes to Financial Statements (cont'd)

cash collateral of approximately $738,000, which is not reflected in the Portfolio of Investments. The Fund has the right under the lending agreement to recover the securities from the borrower on demand.

7.  Structured Investments: The Fund invested a portion of its assets in structured investments. A structured investment is a derivative security designed to offer a return linked to a particular underlying security, currency, commodity or market. Structured investments may come in various forms including notes, warrants and options to purchase securities. The Fund will typically use structured investments to gain exposure to a permitted underlying security, currency, commodity or market when direct access to a market is limited or inefficient from a tax or cost standpoint. Investments in structured investments involve risks including issuer risk, counterparty risk and market risk. Holders of structured investments bear risks of the underlying investment and are subject to issuer or counterparty risk because the Fund is relying on the creditworthiness of such issuer or counterparty and has no rights with respect to the underlying investment. Certain structured investments may be thinly traded or have a limited trading market and may have the effect of increasing the Fund's illiquidity to the extent that the Fund, at a particular time, may be unable to find qualified buyers for these securities.

8.  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.

9.  Other: Security transactions are accounted for on the date the securities are purchased or sold. Interest income is recognized on the accrual basis except where collection is in doubt and is recorded net of foreign withholding tax.

Realized gains (losses) on the sale of investment securities are determined on the specific identified cost basis. Dividend income and distributions are recorded on the ex-dividend date (except certain dividends which may be recorded as soon as the Fund is informed of such dividends) net of applicable withholding taxes.

B.  Advisory Fees: The Adviser, a wholly-owned subsidiary of Morgan Stanley, provides the Fund with advisory services under the terms of an Investment Advisory Agreement, calculated weekly and payable monthly, at an annual rate of 1.00% of the Fund's average weekly net assets.

C.  Administration Fees: The Adviser also serves as 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. The Adviser has agreed to limit the administration fee through a waiver so that it will be no greater than the previous administration fee (prior to November 1, 2004) of 0.02435% of the Fund's average weekly net assets plus $24,000 per annum. This waiver may be terminated at any time. For the year ended December 31, 2012, approximately $139,000 of administration fees were waived pursuant to this arrangement. 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.

D.  Custodian Fees: State Street (the "Custodian") and its affiliates serve as Custodian for the Fund. 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.

Notes to Financial Statements (cont'd)

The Fund has entered into an arrangement with its Custodian whereby credits realized on uninvested cash balances may be used to offset a portion of the Fund's expenses. If applicable, these custodian credits are shown as "Expense Offset" in the Statement of Operations.

E.  Federal Income Taxes: It is the Fund's intention to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for Federal income taxes is required in the financial statements.

Dividend income and distributions to stockholders are recorded on the ex-dividend date. Interest income is recognized on an accrual basis. Dividends from net investment income, if any, are declared and paid quarterly. Net realized capital gains, if any, are distributed at least annually.

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.

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 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 December 31, 2012, 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 2012 and 2011 was as follows:

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, paydown adjustments and basis adjustments for securities sold, resulted in the following reclassifications among the components of net assets at December 31, 2012:

At December 31, 2012, the components of distributable earnings for the Fund on a tax basis were as follows:

Morgan Stanley Emerging Markets Debt Fund, Inc.

December 31, 2012

Notes to Financial Statements (cont'd)

At December 31, 2012, the aggregate cost for federal income tax purposes is approximately $296,702,000. The aggregate gross unrealized appreciation is approximately $41,754,000 and the aggregate gross unrealized depreciation is approximately $328,000 resulting in net unrealized appreciation of approximately $41,426,000.

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the "Modernization Act") was signed into law. The Modernization Act modernizes several tax provisions related to Regulated Investment Companies ("RICs") and their shareholders. One key change made by the Modernization Act is that capital losses will generally retain their character as short-term or long-term and may be carried forward indefinitely to offset future gains. These losses are utilized before other capital loss carryforwards that expire. Generally, the Modernization Act is effective for taxable years beginning after December 22, 2010.

To the extent that capital loss carryforwards are used to offset any future capital gains realized during the carryover period as provided by U.S. Federal income tax regulations, 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 stockholders. During the year ended December 31, 2012, the Fund utilized capital loss carryforwards for U.S. Federal income tax purposes of approximately $2,772,000.

F.  Security Transactions and Transactions with Affiliates: For the year ended December 31, 2012, purchases and sales of investment securities for the Fund, other than long-term U.S. Government securities and short-term investments, were approximately $162,878,000 and $129,789,000, respectively. There were no purchases and sales of long-term U.S. Government securities for the year ended December 31, 2012.

The Fund invests in the Institutional Class of the Morgan Stanley Institutional Liquidity Funds — Money Market Portfolio (the "Liquidity Funds"), an open-end management investment company managed by the Adviser, both directly, and as a portion of the securities held as collateral on loaned securities. Advisory fees paid by the Fund are reduced by an amount equal to its pro-rata share of the advisory and administration fees paid by the Fund due to its investment in the Liquidity Funds. For the year ended December 31, 2012, advisory fees paid were reduced by approximately $21,000 relating to the Fund's investment in the Liquidity Funds.

A summary of the Fund's transactions in shares of the Liquidity Funds during the year ended December 31, 2012 is as follows:

G.  Other: On October 8, 2007, the Fund commenced a share repurchase program for purposes of enhancing stockholder value and reducing the discount at which the Fund's shares trade from their net asset value per share ("NAV"). During the year ended December 31, 2012, the Fund did not repurchase any of its shares. Since the inception of the program, the Fund has repurchased 1,103,336 of its shares at an average discount of 15.74% from NAV. 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.

Election of Directors by all stockholders:

I.  Accounting Pronouncement: In December 2011, FASB issued Accounting Standards Update ("ASU") 2011-11, "Balance Sheet: Disclosures about Offsetting Assets and Liabilities." The pronouncement improves disclosures for recognized financial and derivative instruments that are either offset on the balance sheet in accordance with the offsetting guidance in ASC 210-20-45, "Balance Sheet: Offsetting — Other Presentation Matters" or ASC 815-10-45, "Derivatives: Overall — Other Presentation Matters" or are subject to enforceable master netting agreements or similar agreements. The Fund will be required to disclose information about rights to offset and related arrangements (such as collateral agreements) in order to enable financial statement users to understand the effect of those rights and arrangements on its financial position as well as disclose the following (1) gross amounts; (2) amounts offset in the statement of financial position; (3) any other amounts that can be offset in the event of bankruptcy, insolvency or default of any of the parties (including cash and noncash financial collateral); and (4) the Fund's net exposure. The requirements are effective for annual reporting periods beginning on or after January 1, 2013, and must be applied retrospectively. At this time, the Fund's management is evaluating the implications of ASU 2011-11 and its impact, if any, on the financial statements.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of
Morgan Stanley Emerging Markets Debt Fund, Inc.

We have audited the accompanying statement of assets and liabilities of Morgan Stanley Emerging Markets Debt Fund, Inc. (the "Fund"), including the portfolio of investments, as of December 31, 2012, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with 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. We were not engaged to perform an audit of the Fund's 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 and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2012, by correspondence with the custodian and others. 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 Emerging Markets Debt Fund, Inc. at December 31, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Morgan Stanley Emerging Markets Debt Fund, Inc.

Investment Policy (unaudited)

The Fund may, but 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 on the value of an underlying asset, interest rate, index or financial instrument. 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 they relate, and risks that the transactions may not be liquid. 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. 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 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:

Foreign Currency 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 exchange contract ("currency contract") is a negotiated agreement between two parties to exchange specified amounts of two or more currencies at a specified future time at a specified rate. The rate specified by the currency contract 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. 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 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. Hedging the Fund's currency risks involves the risk of mismatching the Fund's objectives under a currency contract with the value of securities denominated in a particular currency. Furthermore, such transactions 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 an additional risk to the effect 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.

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

Morgan Stanley Emerging Markets Debt Fund, Inc.

December 31, 2012

Investment Policy (unaudited) (cont'd)

the settlement date. A decision as to whether, when and how to use futures 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 can lower total return, and the potential loss from futures can exceed the Fund's initial investment in such contracts.

Options. If a 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 futures contract on the underlying instrument at an agreed-upon price typically in exchange for a premium received by the Fund. 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.

Structured Investments. The Fund also may invest a portion of its assets in structured investments. A structured investment is a derivative security designed to offer a return linked to a particular underlying security, currency, commodity or market. Structured investments may come in various forms including notes, warrants and options to purchase securities. The Fund will typically use structured investments to gain exposure to a permitted underlying security, currency, commodity or market when direct access to a market is limited or inefficient from a tax or cost standpoint. Investments in structured investments involve risks including issuer risk, counterparty risk and market risk. Holders of structured investments bear risks of the underlying investment and are subject to issuer or counterparty risk because the Fund is relying on the creditworthiness of such issuer or counterparty and has no rights with respect to the underlying investment. Certain structured investments may be thinly traded or have a limited trading market and may have the effect of increasing the Fund's illiquidity to the extent that the Fund, at a particular point in time, may be unable to find qualified buyers for these securities.

Swaps. An over-the-counter ("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, indexes, reference rates, currencies or other instruments. A small percentage of swap contracts are cleared through a central clearinghouse. Most 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. Most swap agreements are not entered into or traded on exchanges and often there is no central clearing or guaranty function for swaps. These OTC swaps are often subject to credit risk or the risk of default or non-performance by the counterparty. Swaps could result in losses if interest rate or foreign currency exchange rates or credit quality changes are not correctly anticipated by the Fund or if the reference index, security or investments do not perform as expected.

Dividend Reinvestment and Cash Repurchase Plan (unaudited)

Pursuant to the Dividend Reinvestment Plan (the Plan), each stockholder will be deemed to have elected, unless Computershare Trust Company, N.A. (the Plan Agent) is otherwise instructed by the stockholder in writing, to have all distributions automatically reinvested in Fund shares. Participants in the Plan have the option of making additional voluntary cash payments to the Plan Agent, quarterly, in any amount from $100 to $3,000, for investment in Fund shares.

Dividend and capital gain distributions (Distribution) will be reinvested on the reinvestment date in full and fractional shares. If the market price per share equals or exceeds net asset value per share on the reinvestment date, the Fund will issue shares to participants at net asset value or, if net asset value is less than 95% of the market price on the reinvestment date, shares will be issued at 95% of the market price. If net asset value exceeds the market price on the reinvestment date, participants will receive shares valued at market price. The Fund may purchase shares of its Common Stock in the open market in connection with dividend reinvestment requirements at the discretion of the Board of Directors. Should the Fund declare a Distribution payable only in cash, the Plan Agent will purchase Fund shares for participants in the open market as agent for the participants.

The Plan Agent's fees for the reinvestment of a Distribution will be paid by the Fund. However, each participant's account will be charged a pro rata share of brokerage commissions incurred on any open market purchases effected on such participant's behalf. Although stockholders in the Plan may receive no cash distributions, participation in the Plan will not relieve participants of any income tax which may be payable on such dividends or distributions.

In the case of stockholders, such as banks, brokers or nominees, that hold shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by the stockholder as representing the total amount registered in the stockholder's name and held for the account of beneficial owners who are participating in the Plan.

Stockholders who do not wish to have Distributions automatically reinvested should notify the Plan Agent in writing. There is no penalty for non-participation or withdrawal from the Plan, and stockholders who have previously withdrawn from the Plan may rejoin at any time. Requests for additional information or any correspondence concerning the Plan should be directed to the Plan Agent at:

Once you have informed us about your privacy preferences, your opt-out preference will remain in effect with respect to this Policy (as it may be amended) until you notify us otherwise. If you are a joint account owner, we will accept instructions from any one of you and apply those instructions to the entire account.

Please understand that if you limit our sharing or our affiliated companies' use of personal information, you and any joint account holder(s) may not receive information about our affiliated companies' products and services, including products or services that could help you manage your financial resources and achieve your investment objectives.

If you have more than one account or relationship with us, please specify the accounts to which you would like us to apply your privacy choices. If you have accounts or relationships with our affiliates, you may receive multiple privacy policies from them, and will need to separately notify those companies of your privacy choices for those accounts or relationships.

7. What If an Affiliated Company Becomes a Nonaffiliated Third Party?

If, at any time in the future, an affiliated company becomes a nonaffiliated third party, further disclosures of personal information made to the former affiliated company will be limited to those described in Section 2(b) above relating to nonaffiliated third parties. If you elected under Section 6 to limit disclosures we make to affiliated companies, or use of personal information by affiliated companies, your election will not apply to use by any former affiliated company of your personal information in their possession once it becomes a nonaffiliated third party.
