Dear Shareholder,

We present this Semi-Annual Report, which covers the activities of Aberdeen Global Income Fund, Inc. (the “Fund”), for the six-month period ended April 30, 2017. The Fund’s principal investment objective is to provide high current income by investing primarily in fixed income securities. As a secondary investment objective, the Fund seeks capital appreciation, but only when consistent with its principal investment objective.

NAV Total Return Performance

The Fund’s total return, based on net asset value (“NAV”) net of fees, was 4.8% for the six-month period ended April 30, 2017 and 7.0% per annum since inception, assuming the reinvestment of dividends and distributions. The Fund’s total return for the six-month period ended April 30, 2017 and per annum since inception is based on the reported NAV on each financial reporting period end.

Share Price Total Return Performance & Discount

For the six-month period ended April 30, 2017, based on market price, the Fund’s total return was 7.1% assuming reinvestment of dividends and distributions. The Fund’s share price increased by 1.9% over the six-month period, from $8.46 on October 31, 2016 to $8.62 on April 30, 2017. The Fund’s share price on April 30, 2017 represented a discount of 6.2% to the NAV per share of $9.19 on that date, compared with a discount of 8.2% to the NAV per share of $9.22 on October 31, 2016.

Portfolio Management

The Fund is managed by Aberdeen’s Asia-Pacific fixed income team. The Asia-Pacific fixed income team works in a truly collaborative fashion; all team members have both portfolio management and research responsibilities. The team is responsible for the day-to-day management of the Fund.

Effective March 15, 2017, Lin-Jing Leong replaced Victor Rodriguez as part of the team having the most significant responsibility for the day-to-day management of the Fund’s portfolio. The team also includes Nick Bishop, Kenneth Akintewe, Steven Logan and Adam McCabe.

Ms. Leong is an investment manager on the Asian local rates and currency team. She joined Aberdeen Asset Management Asia Limited in 2013 from the Reserve Management Section of the Central Bank of Malaysia where she specialized in investing in the Asian local current bond market.

Credit Quality

As of April 30, 2017, 17.7% of the Fund’s portfolio was invested in securities where either the issue or the issuer was rated A or better by multiple rating agencies.

Managed Distribution Policy

Distributions to common shareholders for the twelve-month period ended April 30, 2017 totaled $0.84 per share. Based on the share price of $8.62 on April 30, 2017, the distribution rate over the twelve-month period ended April 30, 2017 was 9.7%. Since all distributions are paid after deducting applicable withholding taxes, the effective distribution rate may be higher for those U.S. investors who are able to claim a tax credit.

On May 9, 2017 and June 9, 2017, the Fund announced that it will pay on May 26, 2017 and June 27, 2017 respectively, a distribution of US $0.07 per share to all shareholders of record as of May 19, 2017 and June 20, 2017, respectively.

The Fund’s policy is to provide investors with a stable monthly distribution out of current income, supplemented by realized capital gains and, to the extent necessary, paid-in capital, which is a non-taxable return of capital. This policy is subject to an annual review as well as regular review at the Board’s quarterly meetings, unless market conditions require an earlier evaluation.

Open Market Repurchase Program

The Fund’s policy is generally to buy back Fund shares on the open market when the Fund trades at certain discounts to NAV and management believes such repurchases may enhance shareholder value. During the six-month period ended April 30, 2017 and fiscal year ended October 31, 2016, the Fund repurchased 19,539 and 100,430 shares, respectively.

Revolving Credit Facility

The Fund’s revolving credit facility with The Bank of Nova Scotia was renewed for a 3-year term on February 28, 2017. The outstanding balance on the loan as of April 30, 2017 was $31,500,000. Under the terms of the loan facility and applicable regulations, the Fund is required to maintain certain asset coverage ratios for the amount of its outstanding borrowings. The Board regularly reviews the use of leverage by the Fund. The Fund is also authorized to use reverse repurchase agreements as another form of leverage.

Merger of Aberdeen Asset Management PLC with Standard Life plc

The Fund’s investment manager, investment adviser, investment sub-adviser and administrator are each a subsidiary of Aberdeen Asset Management PLC (“Aberdeen PLC”). On March 6, 2017, the Boards of Standard Life plc and Aberdeen PLC announced that they had reached an agreement on the terms of a merger (“Merger”). The Boards of each of Standard Life plc and Aberdeen PLC believe that the Merger has a compelling strategic and financial rationale through combining complementary strengths to create a world-class

investment group. The Merger is expected to occur in the third quarter of 2017, subject to various conditions and terms, including regulatory approvals. The portfolio management team for the Fund is not expected to change as a result of the Merger. In addition, the agreements that the Fund has with Aberdeen PLC’s subsidiary companies, the services provided by such companies, and the fees charged for those services are not expected to change as a result of the Merger.

Portfolio Holdings Disclosure

The Fund’s complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the Fund’s semi-annual and annual reports to shareholders. The Fund files its complete schedule of portfolio holdings with the Securities and Exchange Commission (“SEC”) for the first and third quarters of each fiscal year on Form N-Q.

A description of the policies and procedures that the Fund uses to determine how to vote proxies relating to portfolio securities, and information regarding how the Fund voted proxies relating to portfolio securities during the most recent twelve months ended June 30 is available by August 31 of the relevant year: (i) upon request and without charge by calling Investor Relations toll-free at 1-800-522-5465; and (ii) on the SEC’s website at http://www.sec.gov.

Unclaimed Share Accounts

Please be advised that abandoned or unclaimed property laws for certain states require financial organizations to transfer (escheat) unclaimed property (including Fund shares) to the state. Each state has its own definition of unclaimed property, and Fund shares could be considered “unclaimed property” due to account inactivity (e.g., no owner-generated activity for a certain period), returned mail (e.g., when mail sent to a shareholder is returned to the Fund’s transfer agent as undeliverable), or a combination of both. If your Fund

shares are categorized as unclaimed, your financial advisor or the Fund’s transfer agent will follow the applicable state’s statutory requirements to contact you, but if unsuccessful, laws may require that the shares be escheated to the appropriate state. If this happens, you will have to contact the state to recover your property, which may involve time and expense. For more information on unclaimed property and how to maintain an active account, please contact your financial adviser or the Fund’s transfer agent.

Market/economic review

Global fixed income markets were volatile over the six-month period ended April 30, 2017. Events in the U.S. held sway, notably Donald Trump’s win in the presidential election in November 2016. This halted the global bond market rally as investors considered the possibility that Trump would increase fiscal spending and lift the inflation outlook. Investors subsequently rotated back into bonds amid growing uncertainty over U.S. trade policies and their potential impact on global recovery. Towards the end of the reporting period, Asian government bonds rallied further as political tensions escalated following U.S. military strikes in Syria and several botched missile tests by North Korea. Meanwhile, the U.S. Federal Reserve (Fed) raised its benchmark interest rate in two 25-basis point increments in December 2016 and March 2017. The European Central Bank and Bank of Japan maintained their loose monetary policy stance. Currencies in the G10 markets were mostly weaker against the U.S. dollar, including the Australian and New Zealand dollars. Emerging-market currencies were mixed: the Russian rouble and Indian rupee led the gains and the Mexican peso and Brazilian real also strengthened, but the Turkish lira and Malaysian ringgit weakened.

Australian and New Zealand government bond yields rose over the reporting period, with the short end of their curves outperforming the long end. In Australia, the central bank kept interest rates on hold as inflation remained entrenched below its 2% target. With the frothy housing market presenting risks to the financial system, macroprudential¹ measures were strengthened, including stricter rules for mortgages. New Zealand yields rose despite the central bank’s interest-rate cut due to rising external risks. However, policymakers’ desire to see a weaker New Zealand dollar subsequently saw them hold rates unchanged.

In Asian local-currency bonds, the Philippines was one of the main laggards as bonds yields trended higher on expectations of rising inflation. Singapore bond yields tracked U.S. Treasury yields higher. On a positive note, Indonesian and Indian bonds outperformed their Asia-Pacific region peers. Investor sentiment in Indonesia was buoyed by hopes that government reform momentum and infrastructure spending was gathering pace. Additionally, President Joko Widodo’s signature tax amnesty program netted 135 trillion rupiah (roughly US$10.1 billion) in revenues. In India, the government’s unexpected decision to replace large rupee denominations resulted in a flood of bank deposits that were channelled into government bonds. The ruling Bharatiya Janata Party’s victory in several state elections also reignited hopes that

economic reforms would accelerate. This helped mask early disappointment over the central bank’s move from an easing bias to a neutral policy stance. In Malaysia, fund outflows accelerated, but the market pared losses after the central bank eased rules on the short-selling of government bonds in an effort to bolster trading volumes and attract more investors.

In other emerging markets, Turkish and Mexican bonds underperformed over the reporting period, despite a late rebound in both markets. In Turkey, confidence over the political situation deteriorated as a controversial referendum win conferred sweeping powers to the president and eliminated the role of the prime minister. In Mexico, the central bank raised interest rates and Donald Trump’s threat to renege on the North American Free Trade Agreement (NAFTA) and other anti-Mexican rhetoric from his campaign trail hurt investor sentiment. Conversely, Brazilian bonds and the Brazilian real performed well as the central bank cut interest rates and maintained a dovish monetary policy stance. Russian yields fell initially on the oil-price rebound and hopes that the economy would benefit from Donald Trump’s presidency. Later in the reporting period, policy rate cuts further bolstered investor sentiment. South African bond yields also fell during the reporting period, despite a credit rating downgrade to non-investment-grade status.

High-yield bonds outside of emerging markets continued to perform well over the reporting period, with spreads tightening as expectations of increased fiscal spending and stronger growth under the Trump administration bolstered investor risk appetite. Concurrently, defaults in the high-yield commodity sector, particularly in the U.S., appeared to be abating. These positive developments helped to soothe investors’ concerns over rising interest rates and volatile oil prices.

Fund performance review

Fund performance over the reporting period benefited from strategies in Australia and New Zealand, as well as emerging-market debt. However, the strategies in Asian local-currency bonds and global high-income debt detracted from Fund performance.

The Fund’s underweight allocations to both Australian bonds and the Australian dollar relative to its blended benchmark² were key contributors to the Fund’s relative performance for the reporting period. In emerging-market debt, security selection in Russia bolstered Fund performance.

The Fund’s strategies in Asian local-currency bonds weighed on performance due mainly to the positions in Malaysian bonds and the

Malaysian ringgit. Nonetheless, the overweight allocation to the Indian rupee mitigated losses as the currency strengthened

significantly against the U.S. dollar over the reporting period. The Fund’s overweight to Indonesian bonds also had a positive impact.

Regarding the global high-income strategies, the main detractor from Fund performance for the reporting period was security selection in investment-grade financial bonds. However, security selection in high-yield oil-and-gas and high-yield financial bonds mitigated the losses.

The Fund’s use of derivatives, primarily for currency management, had an overall positive impact on performance for the reporting period due to short positions in the Australian dollar and New Zealand dollar. This was slightly offset by short positioning in the euro and British pound, both of which ended the period stronger against the U.S. dollar.

Outlook

The global economy seems to be on a cyclical recovery. In the U.S., this is underscored by increases in both hiring and wages. However, we believe that underlying strength over the longer term remains elusive. This is attributable in part to persistent doubts over the effectiveness of the Trump presidency. In Europe, investors are wary of political developments, even though the market-friendly outcome of the French presidential election assuaged fears somewhat. In Asia, North Korea’s belligerence remains a concern, while the potential for systemic risk lingers in China, with the accompanying worries over deleveraging and credit-tightening. Nonetheless, we believe that Beijing will be keen to ensure stability ahead of its Party Congress meeting in late 2017.

We believe that the Fed will not rush to normalize interest rates and the European Central Bank should maintain its easy monetary policy in the near term. In Australia, we believe that the central bank will favor targeted regulatory tweaks over rate hikes in a bid to rein in the frothy housing market, since overall inflation remains below its target. In most parts of the emerging world, inflation remains benign as the price of oil is expected to stay under pressure for some time. Therefore, we think that bond markets should find some support, although we may see a continued reduction in duration³ risk. In our view, government bonds, in particular, could benefit from their relative value. With respect to high-yield credit, we think that the environment remains favorable, although valuations appear elevated. We believe that the recent default cycle in the U.S. energy and commodity sectors may result in a cathartic cleansing of the weakest corporate balance sheets and the rate of defaults could decline. While pockets of weakness persist, among U.S. retailers for example, we feel that the bulk of the market remains in good shape, and we believe

that it still provides investors with the ability to generate decent returns, especially in the context of a low-yielding environment.

Loan Facility and the Use of Leverage

The Fund utilizes leverage to seek to increase the yield for its shareholders. The amounts borrowed from the Fund’s loan facility may be invested to seek to return higher rates than the rates in the Fund’s portfolio. However, the cost of leverage could exceed the income earned by the Fund on the proceeds of such leverage. To the extent that the Fund is unable to invest the proceeds from the use of leverage in assets which pay interest at a rate which exceeds the rate paid on the leverage, the yield on the Fund’s common stock will decrease. In addition, in the event of a general market decline in the value of assets in which the Fund invests, the effect of that decline will be magnified in the Fund because of the additional assets purchased with the proceeds of the leverage. Non-recurring expenses in connection with the implementation of the loan facility will reduce the Fund’s performance.

The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds having similar investment objectives and policies. The funds borrowed pursuant to the loan facility may constitute a substantial lien and burden by reason of their prior claim against the income of the Fund and against the net assets of the Fund in liquidation. The Fund is not permitted to declare dividends or other distributions in the event of default under the loan facility. In the event of default under the loan facility, the lender has the right to cause a liquidation of the collateral (i.e., sell portfolio securities and other assets of the Fund) and, if any such default is not cured, the lender may be able to control the liquidation as well. The loan facility has a term of 3 years and is not a perpetual form of leverage; there can be no assurance that the loan facility will be available for renewal on acceptable terms, if at all.

The credit agreement governing the loan facility includes usual and customary covenants for this type of transaction. These covenants impose on the Fund asset coverage requirements, Fund composition requirements and limits on certain investments, such as illiquid investments, which are more stringent than those imposed on the Fund by the 1940 Act. The covenants or guidelines could impede the Investment Manager, Investment Adviser or the Sub-Adviser from fully managing the Fund’s portfolio in accordance with the Fund’sinvestment objective and policies. Furthermore, non-compliance with such covenants or the occurrence of other events could lead to the cancellation of the loan facility. The covenants also include a requirement that the Fund maintain a NAV of no less than $60,000,000.

Prices and availability of leverage are extremely volatile in the current market environment. The Board regularly reviews the use of leverage by the Fund and may explore other forms of leverage. The Fund is also authorized to use reverse repurchase agreements as another form of leverage. A reverse repurchase agreement involves the sale of a security, with an agreement to repurchase the same or substantially similar securities at an agreed upon price and date. Whether such a transaction produces a gain for the Fund depends upon the costs of the agreements and the income and gains of the securities purchased with the proceeds received from the sale of the security. If the income and gains on the securities purchased fail to exceed the costs, the Fund’s NAV will decline faster than otherwise would be the case. Reverse repurchase agreements, as with any leveraging techniques, may increase the Fund’s return; however, such transactions also increase the Fund’s risks in down markets.

Interest Rate Swaps

The Fund may enter into interest rate swaps to efficiently gain interest rate exposure and hedge interest rate risk. As of April 30, 2017, the Fund held interest rate swap agreements with an aggregate notional amount of $31,500,000 which represented 100% of the Fund’s total borrowings. Under the terms of the agreements

currently in effect, the Fund either receives a floating rate of interest (three month USD-LIBOR BBA rate) and pays fixed rates of interest for the terms or pays a floating rate of interest and receives a fixed rate of interest for the terms, and based upon the notional amounts set forth below:

A significant risk associated with interest rate swaps is the risk that the counterparty may default or file for bankruptcy, in which case the Fund would bear the risk of loss of the amount expected to be received under the swap agreements. There can be no assurance that the Fund will have an interest rate swap in place at any given time nor can there be any assurance that, if an interest rate swap is in place, it will be successful in hedging the Fund’s interest rate risk with respect to the loan facility. The implementation of this strategy is at the discretion of the Leverage Committee of the Board.
