Semi-Annual Report

April 30, 2016

Managed Distribution Policy (unaudited)

The Board of Directors of the Fund has authorized a managed distribution policy (“MDP”) of paying monthly distributions at an annual rate set once a year. The Fund’s current monthly distribution is set at a rate of $0.035 per share. With each distribution, the Fund will issue a notice to shareholders and an accompanying press release which will provide detailed information regarding the amount and estimated composition of the distribution and other information required by the Fund’s MDP exemptive order. The Fund’s Board of Directors may amend or terminate the MDP at any time without prior notice to shareholders; however, at this time, there are no reasonably foreseeable circumstances that might cause the termination of the MDP. You should not draw any conclusions about the Fund’s investment performance from the amount of distributions or from the terms of the Fund’s MDP.

Distribution Disclosure Classification (unaudited)

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.

The Fund is subject to U.S. corporate, tax and securities laws. Under U.S. tax rules, the amount applicable to the Fund and character of distributable income for each fiscal period depends on the actual exchange rates during the entire year between the U.S. Dollar and the currencies in which Fund assets are denominated and on the aggregate gains and losses realized by the Fund during the entire year.

Therefore, the exact amount of distributable income for each fiscal year can only be determined as of the end of the Fund’s fiscal year, October 31. Under Section 19 of the Investment Company Act of 1940, as amended (the “1940 Act”), the Fund is required to indicate the sources of certain distributions to shareholders. The estimated distribution composition may vary from month to month because it may be materially impacted by future income, expenses and realized gains and losses on securities and fluctuations in the value of the currencies in which the Fund’s assets are denominated.

Based on generally accepted accounting principles, the Fund estimates that distributions for the fiscal year commenced November 1, 2015, through the distributions declared on May 10, 2016 and June 9, 2016, consisted of 50% net investment income and 50% return of capital.

In January 2017, a Form 1099-DIV will be sent to shareholders, which will state the amount and composition of distributions and provide information with respect to their appropriate tax treatment for the 2016 calendar year.

Dividend Reinvestment and Direct Stock Purchase Plan (unaudited)

Computershare Trust Company, N.A., (“Computershare”) the Fund’s transfer agent, sponsors and administers a Dividend Reinvestment and Direct Stock Purchase Plan (the “Plan”), which is available to shareholders.

The Plan allows registered stockholders and first time investors to buy and sell shares and automatically reinvest dividends and capital gains through the transfer agent. This is a cost-effective way to invest in the Fund.

Please note that for both purchases and reinvestment purposes, shares will be purchased in the open market at the current share price and cannot be issued directly by the Fund.

For more information about the Plan and a brochure that includes the terms and conditions of the Plan, please call Computershare at 1-800-647-0584 or visit www.computershare.com/buyaberdeen.

Letter to Shareholders (unaudited)

Dear Shareholder,

We present this Semi-Annual Report which covers the activities of Aberdeen Asia-Pacific Income Fund, Inc. (the “Fund”) for the six-month period ended April 30, 2016. The Fund’s principal investment objective is to seek current income. The Fund may also achieve incidental capital appreciation.

Total Return Performance

The Fund’s total return, based on net asset value (“NAV”), net of fees, was 6.9% for the six-month period ended April 30, 2016 and 8.2% per annum since inception, assuming the reinvestment of dividends and distributions. The Fund’s total return for the six-month period ended April 30, 2016 and per annum since inception is based on the reported NAV on each financial reporting period end.

Share Price and NAV

For the six-month period ended April 30, 2016, based on market price, the Fund’s total return was 11.0%, assuming reinvestment of dividends and distributions. The Fund’s share price increased by 6.1% over the six-month period, from $4.75 on October 31, 2015 to $5.04 on April 30, 2016. The Fund’s share price on April 30, 2016 represented a discount of 11.4% to the NAV per share of $5.69 on that date, compared with a discount of 14.7% to the NAV per share of $5.57 on October 31, 2015.

Portfolio Allocation

As of April 30, 2016, the Fund held 37.7% of its total investments in Australian debt securities, 56.1% in Asian debt securities, 4.5% in European debt securities and 1.7% in U.S. debt securities.

Of the Fund’s total investments, 39.1% were held in U.S. Dollar-denominated bonds issued by foreign issuers. The rest of the Fund’s currency exposure was 40.4% in the Australian Dollar and 20.5% in various Asian currencies.

Since April 30, 2016, the Fund has introduced investments in higher yielding Asian local currency markets, such as India and Indonesia,

and slightly reduced its Australian exposure. In addition, the Fund’s blended benchmark will change effective July 31, 2016. Please see “Subsequent Events,” Note 14 to the Notes to Financial Statements for more information about the new benchmark.

Credit Quality

As of April 30, 2016, 58.7% of the Fund’s total investments were invested in securities where either the issue or the issuer was rated A or better by Standard & Poor’s 1 or Moody’s Investors Services, Inc (“Moody’s”).2

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 jointly and primarily responsible for the day-to-day management of the Fund.

Managed Distribution Policy

Distributions to common shareholders for the twelve-month period ended April 30, 2016 totaled $0.42 per share. Based on the share price of $5.04 on April 30, 2016, the distribution rate over the twelve-month period ended April 30, 2016 was 8.3%. 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 10, 2016 and June 9, 2016, the Fund announced that it will pay on May 27, 2016 and June 27, 2016 a distribution of US $0.035 per share to all shareholders of record as of May 19, 2016 and June 20, 2016, 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.

Fund’s Leverage

The table below summarizes certain key terms of the Fund’s current leverage:

|  | Amount ($ in millions) |  |  | Maturity |
Revolving Credit Facility |  | $ | 125 |  |  |  | April 9, 2017 |
7-year Series A Senior Secured Notes |  | $ | 100 |  |  |  | June 12, 2020 |
10-year Series B Senior Secured Notes |  | $ | 100 |  |  |  | June 12, 2023 |
5-year Term Loan A |  | $ | 100 |  |  |  | June 12, 2018 |
4-year Term Loan B |  | $ | 100 |  |  |  | December 14, 2019 |
10-year Series A Mandatory Redeemable Preferred Shares |  | $ | 50 |  |  |  | June 27, 2023 |

The Series A Mandatory Redeemable Preferred Shares, with a liquidation value of $50 million, are rated AA by Fitch Ratings 3 and the combined $200 million 7- and 10-year Series A and B Senior Secured Notes are rated AAA by Fitch Ratings.

We believe the Fund has been able to lock in an attractive rate cost of borrowing and extend the maturity of the leverage facility while diversifying its borrowing structure during what we believe to be a favorable current interest rate environment. A more detailed description of the Fund’s leverage can be found in the Report of Investment Manager and the Notes to Financial Statements.

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, 2016 and fiscal year ended October 31, 2015, the Fund repurchased 1,676,887 and 4,991,465 shares, respectively.

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. The Fund’s Form N-Q filings are available on the SEC’s website at http://www.sec.gov and may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. Information about the operation of the Public Reference Room may be obtained by calling 1-800-SEC-0330. The Fund makes the information on Form N-Q available to shareholders

on the Fund’s website or upon request and without charge by calling Investor Relations toll-free at 1-800-522-5465.

Proxy Voting

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.

Report of the Investment Manager (unaudited)

Market review

Most Asia-Pacific and emerging-market (EM) bond markets strengthened in local-currency terms over the six-month period ended April 30, 2016. The first half of the reporting period was marked by heightened global volatility. A confluence of events, such as the U.S. Federal Reserve’s (Fed’s) first interest-rate hike in nearly a decade, sharp gyrations in Chinese equities and the tumble in commodity prices, quelled investor risk appetite for Asia-Pacific bonds. Market sentiment gradually recovered in the latter months of the period. Although investors questioned the effectiveness of negative interest rates imposed by central banks in Europe and Japan, they appeared to be encouraged that monetary policy generally remained loose, as Asian central banks continued to lower rates and the Fed adopted a more dovish policy stance. Additionally, Chinese economic growth fears abated as Beijing’s policy communication improved and commodity prices rebounded beginning in mid-February 2016.

In Australia, performance in government bonds varied over the reporting period, with longer-dated yields falling and shorter-dated yields rising. The central bank remained accommodative as deflationary pressures persisted. (Following the end of the reporting period, the benchmark rate was trimmed by 25 basis points to a record low of 1.75%.) The performance of the New Zealand market was significantly stronger over the period. As the country struggled with weak inflation, the central bank cut its benchmark interest rate twice and yields subsequently declined in response. Both the Australian and New Zealand dollars strengthened against the U.S. dollar, with the former rallying 6.5% during the reporting period following improvement in investor sentiment towards China, a key export market for the country.

Indonesian and Indian government bonds outperformed their Asian peers during the reporting period due to their respective central bank interest-rate cuts. The Indonesian market was also bolstered by stimulus measures in an effort to reboot the economy, while India gained further on the central bank’s liquidity-boosting measures and the announcement of a fiscally prudent budget, which eased initial investor concerns over a higher public wage bill. Bond markets in Taiwan, Thailand and Korea performed well over the period, particularly at the long end of the yield curve. Taiwan’s central bank eased monetary policy, while hopes of additional rate cuts buttressed the markets in Thailand and Korea. Singapore bond yields also moved lower over the reporting period, but the rally lost momentum after the central bank unexpectedly removed the appreciation bias from its currency policy, reflecting its concerns over slowing economic growth. Malaysian yields retreated on keen

buying interest as valuations became more attractive, but profit-taking later ensued.

The weaker U.S. dollar benefited most Asian currencies over the reporting period: the Malaysian ringgit and Indonesian rupiah saw notable gains, rebounding from underperformance in the previous six months; the Korean won and Philippine peso also rallied but ended the period largely unchanged; the Indian rupee and Chinese yuan declined partly on the back of equity outflows in their respective markets.

In Asian credit markets, investment-grade spreads narrowed, but high-yield spreads generally widened, particularly among sovereign bonds. The markets’ performance was influenced significantly by commodity prices, which tumbled initially, but later rebounded as fears over China’s economy subsided. Towards the end of the reporting period, however, rising defaults in the Chinese onshore market dampened investor sentiment again.

Fund performance review

Fund performance over the reporting period was hindered mainly by security selection in the Asian local-currency government bond and Asian U.S. dollar-denominated credit segments. On a positive note, security selection in Australian and New Zealand bonds contributed to performance.

The Fund’s underweight positions in the Malaysian ringgit and Thai bonds also weighed on performance. Conversely, the overweight allocation to Indian government bonds had a positive impact on Fund performance.

In Asian U.S. dollar-denominated credits, the overweight to the volatile high-yield oil-and-gas sector detracted from the Fund’s relative performance. But the overweight to more stable investment-grade credits in the same sector contributed to performance.

Within the Australia and New Zealand portion of the Fund, both the currency and interest rate strategies were positive, with the former contributing the bulk of relative outperformance.

The overall impact from the Fund’s use of derivatives was negative. The impact of currency management in the Asian local-currency bond segment via forwards was relatively flat. In the overlay, derivatives used for interest-rate management and currency management detracted from performance, subtracting about 107 basis points from its return, particularly because of the long U.S. dollar-short Australian dollar position, given the Australian dollar’s strong rally over the first four months of 2016.

Outlook

We think that it may be an exaggeration to say that March was a turning point for commodity-related and emerging markets. We believe that the environment remains in a state of flux. Risks persist, but markets are no longer on a downward trajectory with no end in sight, in our opinion. The Fed has adopted a more dovish stance and global monetary policy generally remains accommodative. While the Chinese economy faces hurdles, we feel that investor sentiment towards the mainland has become more rational as the economic and political backdrop continues to stabilize. Furthermore, commodity markets have arguably tested their lows, even though we believe that the weak global economy is unlikely to be able to support a sustained rally in prices. These factors have encouraged investors to reduce their significant underweight exposure to emerging markets.

In the near term, however, we think that further market consolidation is likely, even if valuations look attractive in bonds, equities and currencies. Additionally, China-related concerns may resurface, given worries about speculation in commodities in the mainland and the rising number of corporate defaults. Nevertheless, we believe that any spike in volatility and swings in valuations may present us with buying opportunities.

In Australia, the economy appears to be on firmer footing and we believe that gross domestic product (GDP) growth will reach around 2.5% for the 2016 calendar year.1 Despite our positive outlook, however, we think that wages and price pressures could remain subdued amid ongoing slack in the labor market. We forecast core consumer-price inflation to remain below the Reserve Bank of Australia’s target range of 2-3% for some time.2 In our opinion, the central bank’s decision to cut the cash rate in May 2016 demonstrates its heightened concerns that inflation may fall short of its target. To boost price pressures, we believe that the level of exchange rate will likely matter to the central bank as well. Nonetheless, we believe that monetary policy easing this time will be gradual as there is no crisis of confidence that was present in the last easing cycle. Although the stabilization in commodity prices has been a key support for the Australian dollar, we think that domestic factors, particularly when coupled with a generally cautious tone, continue to suggest some downside risks in the Australian dollar. In New Zealand, we believe that the weak inflation outlook, coupled with headwinds associated with the dairy sector, may lead to further cuts in the policy rate to 1.75% before the end of 2016,3 and could also weigh on the New Zealand dollar.

Loan Facilities and the Use of Leverage

The amounts borrowed under the Revolving Credit Facility, the Term Loan Facility, the Notes and the Series A MRPS (each as defined below) may be invested to seek to return higher rates than the rates pursuant to which interests or dividends are paid under such forms of leverage. 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.

The Fund employed leverage obtained via bank borrowing and other forms of leverage during the reporting period. On April 9, 2014, the Fund renewed its $150 million revolving credit facility for a 3-year period with a syndicate of banks (the “Revolving Credit Facility”). On June 12, 2013, the Fund entered into a note purchase agreement (the “Note Purchase Agreement”) with institutional investors relating to the private placement of $200 million of senior secured notes rated `AAA’ by Fitch Ratings, $100 million due June 12, 2020 and $100 million due June 12, 2023 (the “Notes”). On the same day, the Fund also entered into a term loan agreement providing for $200 million in secured term loans from Bank of America, N.A., $100 million due June 12, 2016, on December 14, 2015, the maturity of this loan was extended to December 14, 2019, and $100 million due June 12, 2018 (the “Term Loan Facility”). On June 27, 2013, the Fund issued a private offering of 2 million shares of Series A Mandatory Redeemable Preferred Shares due June 25, 2023 (the “Series A MRPS”). The Series A MRPS have a liquidation value of $50 million and are rated ‘AA’ by Fitch Ratings. The Fund’s outstanding balance as of April 30, 2016 was $125 million on the Revolving Credit Facility.

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 Revolving Credit Facility, the Term Loan Facility and the Notes 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 limited in its ability to declare dividends or other distributions under the terms of the various forms of leverage. In the event of an event of default under either the Revolving Credit Facility or Term Loan Facility, the lenders have 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 lenders may be able to control the liquidation as well. In the event of an event of default under the Note Purchase Agreement, the holders of the Notes have the right to cause a liquidation of the collateral (i.e., cause the sale of portfolio securities and other assets of the Fund).

Each of the Revolving Credit Facility Agreement, the Term Loan Agreement, the Note Purchase Agreement, and the Securities Purchase Agreement relating to the Series A MRPS, includes usual and customary covenants for the applicable 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 Fund’s investment manager, investment adviser, or sub-adviser from fully managing the Fund’s portfolio in accordance with the Fund’s investment objective and policies. Furthermore, non-compliance with such covenants or the occurrence of other events could lead to the cancellation of any and/or all of the forms of leverage. As of April 30, 2016, the Fund was in compliance with all covenants under the agreements relating to the various forms of leverage.

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, 2016, the Fund held interest rate swap agreements with an aggregate notional amount of $125 million, which represented 100% of the Fund’s Revolving Credit Facility. Under the terms of the agreements currently in effect, the Fund receives a floating rate of interest (three month USD-LIBOR BBA rate) and pays fixed rates of interest for the terms and based upon the notional amounts set forth below:

Remaining Terms as of April 30, 2016 |  | Amount (in millions) |  |  | Fixed Rate Payable (%) |
6 months |  | $ | 59.0 |  |  |  | 1.42 |
18 months |  | $ | 66.0 |  |  |  | 0.84 |

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.

Total Investment Return (unaudited)

The following table summarizes the average annual Fund performance for the 1-year, 3-year, 5-year and 10-year periods as of April 30, 2016. The Fund’s principal investment objective is to seek current income. The Fund may also achieve incidental capital appreciation.

Aberdeen Asset Management Inc. (“AAMI”) has entered into an agreement with the Fund to limit investor relation services fees, without which performance would be lower. For the six-month period ended April 30, 2016, AAMI did not waive any investor relation service fees because the Fund did not reach the capped amount. See Note 3 in the Notes to Financial Statements. Returns represent past performance. Total investment return at net asset value (NAV) is based on changes in the NAV of Fund shares and assumes reinvestment of dividends and distributions, if any, at market prices pursuant to the dividend reinvestment program sponsored by the Fund’s transfer agent. All return data at NAV includes fees charged to the Fund, which are listed in the Fund’s Statement of Operations under “Expenses”. The Fund’s total return is based on the reported NAV on each financial reporting period end. Total investment return at market value is based on changes in the market price at which the Fund’s shares traded on the NYSE MKT during the period and assumes reinvestment of dividends and distributions, if any, at market prices pursuant to the dividend reinvestment program sponsored by the Fund’s transfer agent. Because the Fund’s shares trade in the stock market based on investor demand, the Fund may trade at a price higher or lower than its NAV. Therefore, returns are calculated based on both market price and NAV. Past performance is no guarantee of future results. The performance information provided does not reflect the deduction of taxes that a shareholder would pay on distributions received from the Fund. The current performance of the Fund may be lower or higher than the figures shown. The Fund’s yield, return, market price and NAV will fluctuate. Performance information current to the most recent month-end is available at www.aberdeenfax.com or by calling 800-522-5465.

The annualized net operating expense ratio based on the six-month period ended April 30, 2016 was 2.24%. The annualized net operating expense ratio, excluding interest expense and distributions to Series A Mandatory Redeemable Preferred Shares, based on the six-month period ended April 30, 2016 was 1.16%.

Financial Highlights (concluded)

(a) |  | Based on average shares outstanding.

(b) |  | Total investment return based on market value is calculated assuming that shares of the Fund’s common stock were purchased at the closing market price as of the beginning of the period, dividends, capital gains, and other distributions were reinvested as provided for in the Fund’s dividend reinvestment plan and then sold at the closing market price per share on the last day of the period. The computation does not reflect any sales commission investors may incur in purchasing or selling shares of the Fund. The total investment return based on the net asset value is similarly computed except that the Fund’s net asset value is substituted for the closing market value.

(c) |  | The total return shown above includes the impact of financial statement rounding of the NAV per share and/or financial statement adjustments.

(d) |  | Ratios calculated on the basis of income, expenses and preferred share dividends applicable to both the common and preferred shares relative to the average net assets of common shareholders. For the six-month period ended April 30, 2016 and fiscal years ended October 31, 2015, 2014, 2013, 2012 and 2011, the ratios of net investment income before preferred stock dividends to average net assets of common shareholders were 4.45%, 4.79%, 4.26%, 4.10%, 4.85% and 5.30%, respectively.

(e) |  | The expense ratio includes a one-time expense associated with the August 2011 shelf offering costs attributable to the registered but unsold shares expiring in August 2015.

(f) |  | Annualized.

(g) |  | Asset coverage ratio is calculated by dividing net assets plus the amount of any borrowings, including Series A Mandatory Redeemable Preferred Shares, for investment purposes by the amount of any long-term debt obligations, which includes the senior secured notes, revolving credit facility and term loans.

(h) |  | Asset coverage ratio is calculated by dividing net assets plus the amount of any borrowings, including Series A Mandatory Redeemable Preferred Shares, for investment purposes by the amount of any borrowings.

1. Organization

Aberdeen Asia-Pacific Income Fund, Inc. (the “Fund”) was incorporated in Maryland on March 14, 1986 as a closed-end, non-diversified management investment company. The Fund’s principal investment objective is to seek current income. The Fund may also achieve incidental capital appreciation. To achieve its investment objectives, the Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Asian debt securities, Australian debt securities and New Zealand debt securities. This 80% investment policy is a non-fundamental policy of the Fund and may be changed by the Fund’s Board of Directors (the “Board”) upon 60 days’ prior written notice to shareholders. There can be no assurance that the Fund will achieve its investment objectives. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic developments in a specific industry, country or region.

The Fund may invest up to 80% of its total assets, plus the amount of any borrowings for investment purposes, in “Asian debt securities,” which include: (1) debt securities of Asian Country (as defined below) issuers, including securities issued by Asian Country governmental entities, as well as by banks, companies and other entities which are located in Asian Countries, whether or not denominated in an Asian Country currency; (2) debt securities of other issuers denominated in, or linked to, the currency of an Asian Country, including securities issued by supranational issuers, such as The World Bank and derivative debt securities that replicate, or substitute for, the currency of an Asian Country; (3) debt securities issued by entities which, although not located in an Asian Country, derive at least 50% of their revenues from Asian Countries or have at least 50% of their assets located in Asian Countries; and (4) debt securities issued by a wholly-owned subsidiary of an entity located in an Asian Country, provided that the debt securities are guaranteed by the parent entity located in the Asian Country. With reference to items (3) and (4) above, Asian debt securities may be denominated in an Asian Country currency or in Australian, New Zealand or U.S. dollars. The maximum country exposure to any one Asian Country (other than Korea) is limited to 20% of the Fund’s total assets and the maximum currency exposure to any one Asian Country currency (other than Korea) is limited to 10% of the Fund’s total assets. The maximum country exposure for Korea is limited to 40% of the Fund’s total assets, and the maximum currency exposure for Korea is limited to 25% of the Fund’s total assets.

“Asian Countries” (each, an “Asian Country”) include Bangladesh, China, Hong Kong, India, Indonesia, Japan, Malaysia, Pakistan, the Philippines, Singapore, South Korea, Taiwan, Thailand, Vietnam, Sri Lanka, Kazakhstan and Mongolia, and such other countries on the

Asian continent approved for investment by the Board of Directors upon the recommendation of Aberdeen Asset Management Asia Limited, the Fund’s investment manager (“AAMAL” or the “Investment Manager”).

2. Summary of Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The policies conform to accounting principles generally accepted in the United States of America (“GAAP”). The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses for the period. Actual results could differ from those estimates. The accounting records of the Fund are maintained in U.S. Dollars and the U.S. Dollar is used as both the functional and reporting currency. However, the Australian Dollar is the functional currency for U.S. federal tax purposes.

a. Security Valuation:

The Fund values its securities at current market value or fair value, consistent with regulatory requirements. “Fair Value” is defined in the Fund’s valuation and liquidity procedures as the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants without a compulsion to contract at the measurement date.

Long-term debt and other fixed-income securities are valued at the last quoted or evaluated bid price on the valuation date provided by an independent pricing service provider approved by the Board. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades occur in smaller “odd lot” sizes at lower prices than institutional round lot trades. If there are no current day bids, the security is valued at the previously applied bid. Short-term debt securities (such as commercial paper and U.S. treasury bills) having a remaining maturity of 60 days or less are valued at amortized cost, if it represents the best approximation of fair value. Debt and other fixed-income securities are generally determined to be Level 2 investments.

Derivatives are valued at fair value. Exchange traded derivatives are generally Level 1 investments and over-the-counter derivatives are generally Level 2 investments. Forward foreign currency contracts are generally valued based on the bid price of the forward rates and the current spot rate. Forward exchange rate quotations are available for scheduled settlement dates, such as 1-, 3-, 6-, 9- and 12-month

Aberdeen Asia-Pacific Income Fund, Inc.

periods. An interpolated valuation is derived based on the actual settlement dates of the forward contracts held. Futures contracts are valued at the settlement price or at the last bid price if no settlement price is available. Interest rate swaps agreements are generally valued by an approved pricing agent based on the terms of the swap agreement (including future cash flows).

In the event that a security’s market quotations are not readily available or are deemed unreliable, the security is valued at fair value as determined by the Fund’s Pricing Committee, taking into account the relevant factors and surrounding circumstances using valuation policies and procedures approved by the Board. A security that has been fair valued by the Fund’s Pricing Committee may be classified as Level 2 or 3 depending on the nature of the inputs.

In accordance with the authoritative guidance on fair value measurements and disclosures under GAAP, the Fund discloses the fair value of its investments using a three-level hierarchy that classifies the inputs to valuation techniques used to measure the fair value. The hierarchy assigns Level 1 measurements to valuations based upon unadjusted quoted prices in active markets for identical assets, Level 2 measurements to valuations based upon other

significant observable inputs, including adjusted quoted prices in active markets for similar assets, and Level 3 measurements to valuations based upon unobservable inputs that are significant to the valuation. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability, which are based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. A financial instrument’s level within the fair value hierarchy is based upon the lowest level of any input that is significant to the fair value measurement. The three-level hierarchy of inputs is summarized below:

Level 1 – quoted prices in active markets for identical investments;

Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, and credit risk); or

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

A summary of standard inputs is listed below:

Security Type |  | Standard Inputs
Debt and other fixed-income securities |  | Reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, credit quality, yield, and maturity.
Forward foreign currency contracts |  | Forward exchange rate quotations.
Swap agreements |  | Market information pertaining to the underlying reference assets, i.e., credit spreads, credit event probabilities, fair values, forward rates, and volatility measures.

For movements between the Levels within the fair value hierarchy, the Fund has adopted a policy of recognizing transfers at the end of each period. During the six-month period ended April 30, 2016, Green Dragon Gas Ltd. transferred from Level 3 to Level 2 because it was not a single broker priced security at April 30, 2016. For the six-month period ended April 30, 2016, there were no significant changes to the fair valuation methodologies.

b. Repurchase Agreements:

The Fund may enter into repurchase agreements under the terms of a Master Repurchase Agreement. It is the Fund’s policy that its custodian/counterparty segregate the underlying collateral securities, the value of which exceeds the principal amount of the repurchase transaction, including accrued interest. The repurchase price generally equals the price paid by the Fund plus interest negotiated on the basis of current short-term rates. To the extent that any repurchase transaction exceeds one business day, the collateral is valued on a daily basis to determine its adequacy. Under the Master Repurchase Agreement, if the counterparty defaults and the value of the collateral declines, or if bankruptcy proceedings are commenced with respect to the counterparty of the repurchase agreement,

realization of the collateral by the Fund may be delayed or limited. The Fund held a repurchase agreement of $36,261,000 as of April 30, 2016. The value of the related collateral exceeded the value of the repurchase agreement at April 30, 2016. Repurchase agreements are subject to contractual netting arrangements with the counterparty, Fixed Income Clearing Corp. For additional information on the Fund’s repurchase agreement, see the Portfolio of Investments.

c. Restricted Securities:

Restricted securities are privately-placed securities whose resale is restricted under U.S. securities laws. The Fund may invest in restricted securities, including unregistered securities eligible for resale without registration pursuant to Rule 144A and privately-placed securities of U.S. and non-U.S. issuers offered outside the U.S. without registration pursuant to Regulation S under the Securities Act of 1933, as amended (the “1933 Act”). Rule 144A securities may be freely traded among certain qualified institutional investors, such as the Fund, but resale of such securities in the U.S. is permitted only in limited circumstances.

d. Foreign Currency Translation:

Foreign securities, currencies, and other assets and liabilities denominated in foreign currencies are translated into U.S. Dollars at

Aberdeen Asia-Pacific Income Fund, Inc.

28

Notes to Financial Statements (unaudited) (continued)

April 30, 2016

the exchange rate of said currencies against the U.S. Dollar, as of the “Valuation Time,” as provided by an independent pricing service approved by the Board. The Valuation Time is as of the close of regular trading on the New York Stock Exchange (usually 4:00 p.m. Eastern Time).

Foreign currency amounts are translated into U.S. Dollars on the following basis:

(i) |  | market value of investment securities, other assets and liabilities – at the current daily rates of exchange at the Valuation Time; and

(ii) |  | purchases and sales of investment securities, income and expenses – at the relevant rates of exchange prevailing on the respective dates of such transactions.

The Fund isolates that portion of the results of operations arising from changes in the foreign exchange rates due to the fluctuations in the market prices of the securities held at the end of the reporting period. Similarly, the Fund isolates the effect of changes in foreign exchange rates from the fluctuations arising from changes in the market prices of portfolio securities sold during the reporting period.

Net exchange gain/(loss) is realized from sales and maturities of portfolio securities, sales of foreign currencies, settlement of securities transactions, dividends, interest and foreign withholding taxes recorded on the Fund’s books. Net unrealized foreign exchange appreciation/(depreciation) includes changes in the value of portfolio securities and other assets and liabilities arising as a result of changes in the exchange rate. The net realized and unrealized foreign exchange gain/(loss) shown in the composition of net assets represents foreign exchange gain/(loss) for book purposes that may not have been recognized for tax purposes.

Foreign security and currency transactions may involve certain considerations and risks not typically associated with those of domestic origin, including unanticipated movements in the value of the foreign currency relative to the U.S. Dollar. Generally, when the U.S. Dollar rises in value against foreign currency, the Fund’s investments denominated in that currency will lose value because its currency is worth fewer U.S. Dollars; the opposite effect occurs if the U.S. Dollar falls in relative value.

e. Derivative Financial Instruments:

The Fund is authorized to use derivatives to manage currency, interest rate and credit risk and as a substitute for physical securities. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. The use of derivative instruments involves, to varying degrees, elements of market risk in excess of the amount recognized in the Statement of Assets and Liabilities.

Forward Foreign Currency Exchange Contracts:

A forward foreign currency exchange contract (“forward contract”) involves an obligation to purchase and sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. Forward contracts are used to manage the Fund’s currency exposure in an efficient manner. They are used to sell unwanted currency exposure that comes with holding securities in a market, or to buy currency exposure where the exposure from holding securities is insufficient to give the desired currency exposure either in absolute terms or relative to the benchmark. The use of forward contracts allows the separation of decision-making between markets and their currencies.

The forward contract is marked-to-market daily and the change in market value is recorded by the Fund as unrealized appreciation or depreciation. Forward contracts’ prices are received daily from an independent pricing provider. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. These realized and unrealized gains and losses are reported on the Statement of Operations. The Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts or from unanticipated movements in exchange rates. During the six-month period ended April 30, 2016, the Fund used forward contracts to hedge and efficiently manage Australian and certain Asian currency exposure.

While the Fund may enter into forward contracts to seek to reduce currency exchange rate risks, transactions in such contracts involve certain risks. The Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts and from unanticipated movements in exchange rates. Thus, while the Fund may benefit from such transactions, unanticipated changes in currency prices may result in a poorer overall performance for the Fund than if it had not engaged in any such transactions. Moreover, there may be imperfect correlation between the Fund’s portfolio holdings or securities quoted or denominated in a particular currency and forward contracts entered into by the Fund. Such imperfect correlation may prevent the Fund from achieving a complete hedge, which will expose the Fund to the risk of foreign exchange loss.

Forward contracts are subject to the risk that a counterparty to such contracts may default on their obligations. Since a forward foreign currency exchange contract is not guaranteed by an exchange or clearing house, a default on the contract would deprive the Fund of unrealized profits, transaction costs or the benefits of a currency hedge or force the Fund to cover its purchase or sale commitments, if any, at the market price at the time of the default.

Futures Contracts:

The Fund may invest in financial futures contracts (“futures contracts”) for the purpose of hedging its existing portfolio securities, or securities that the Fund intends to purchase, against fluctuations in value caused by changes in prevailing market interest rates or prices. Futures contracts may also be entered into for non-hedging purposes, however, in those instances, (a) either the aggregate initial margin and premiums required to establish the Fund’s position may not exceed 5% of the Fund’s NAV after taking into account unrealized profits and unrealized losses on any such contract into which it has entered into, or (b) the aggregate net notional value of the Funds’ position may not exceed 100% of the Fund’s NAV after taking into account unrealized profits and unrealized losses on any such contract which it has entered into.

Upon entering into a futures contract, the Fund is required to pledge to the broker an amount of cash and/or other assets equal to a certain percentage of the contract amount. This payment is known as initial margin. Subsequent payments, known as “variation margin,” are calculated each day, depending on the daily fluctuations in the fair value/market value of the underlying assets. An unrealized gain/(loss) equal to the variation margin is recognized on a daily basis. When the contract expires or is closed, the gain/loss is realized and is presented in the Statement of Operations as a net realized gain/(loss) on futures contracts. Futures contracts are valued daily at their last quoted sale price on the exchange on which they are traded.

A “sale” of a futures contract means a contractual obligation to deliver the securities or foreign currency called for by the contract at a fixed price at a specified time in the future. A “purchase” of a futures contract means a contractual obligation to acquire the securities or foreign currency at a fixed price at a specified time in the future. During the six-month period ended April 30, 2016, the Fund used U.S. Treasury futures to efficiently manage U.S. interest rate exposure and hedge the U.S. interest rate risk.

There are significant risks associated with the Fund’s use of futures contracts, including the following: (1) the success of a hedging strategy may depend on the ability of the Fund’s investment adviser and/or sub-adviser to predict movements in the prices of individual securities, fluctuations in markets and movements in interest rates; (2) there may be an imperfect or no correlation between the movement in the price of futures contracts, interest rates and the value/market value of the securities held by the Fund; (3) there may not be a liquid secondary market for a futures contract; (4) trading restrictions or limitations may be imposed by an exchange; and (5) government regulations may restrict trading in futures contracts. In addition, should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the futures contracts and may realize a loss.

Swaps:

A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset or notional principal amount. The Fund will enter into swaps only on a net basis, which means that the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the difference between the two payments. Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interest payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of each counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying reference asset or index. The Fund records unrealized gains/(losses) on a daily basis representing the value and the current net receivable or payable relating to open swap contracts. Net amounts received or paid on the swap contract are recorded as realized gains/(losses). Fluctuations in the value of swap contracts are recorded for financial statement purposes as unrealized appreciation or depreciation of swap contracts. Realized gains/(losses) from terminated swaps are included in net realized gains/(losses) on swap contracts transactions. During the six-month period ended April 30, 2016, the Fund used interest rate swaps to hedge the interest rate risk on the Fund’s Revolving Credit Facility (as defined below).

The Fund is a party to International Swap Dealers Association, Inc. Master Agreements (“ISDA Master Agreements”). These agreements are with select counterparties and they govern transactions, including certain over-the-counter derivative and foreign exchange contracts, entered into by the Fund and the counterparty. The ISDA Master Agreements maintain provisions for general obligations, representations, agreements, collateral, and events of default or termination.

The occurrence of a specified event of termination may give a counterparty the right to terminate all of its contracts and affect settlement of all outstanding transactions under the applicable ISDA Master Agreement.

Certain swaps, including some interest rate swaps, when entered into, must be cleared pursuant to U.S. Commodity Futures Trading Commission (“CFTC”) regulations. As a result, these swaps can no longer be traded over-the-counter and are subject to various regulations and rules of the CFTC. The Fund does not hold any swaps that are subject to mandatory clearing. In a centrally cleared

derivative transaction, the Fund typically enters into the transaction with a financial institution counterparty, and performance of the transaction is effectively guaranteed by a central clearinghouse, thereby reducing or eliminating the Fund’s exposure to the credit risk of its original counterparty. The Fund will be required to post

specified levels of margin with the clearinghouse or at the instruction of the clearinghouse; the margin required by a clearinghouse may be greater than the margin the Fund would be required to post in an uncleared transaction. Only a limited number of transactions are currently eligible for clearing.

f. Security Transactions, Investment Income and Expenses:

Security transactions are recorded on the trade date. Realized and unrealized gains/(losses) from security and currency transactions are calculated on the identified cost basis. Interest income and expenses are recorded on an accrual basis. Discounts and premiums on securities purchased are accreted or amortized on an effective yield basis over the estimated lives of the respective securities. Expenses are accrued on a daily basis.

g. Distributions:

The Fund has a managed distribution policy to pay distributions from net investment income supplemented by net realized foreign

exchange gains, net realized short-term capital gains and return of capital distributions, if necessary, on a monthly basis. The managed distribution policy is subject to regular review by the Board. The Fund will also declare and pay distributions at least annually from net realized gains on investment transactions and net realized foreign exchange gains, if any. Dividends and distributions to shareholders are recorded on the ex-dividend date.

Dividends and distributions to shareholders are determined in accordance with federal income tax regulations, which may differ from GAAP. These differences are primarily due to differing treatments for foreign currencies, loss deferrals and recognition of market discount and premium.

Distributions to Series A Mandatory Redeemable Preferred Shares (the “Series A MRPS”) shareholders are accrued daily and paid quarterly based on an annual rate of 4.125%. The Fund may not pay distributions to its preferred shareholders unless (i) the pro forma asset coverage ratios for the Series A MRPS, as calculated in accordance with the Fitch Ratings total and net overcollateralization tests per the ‘AA’ rating guidelines outlined in Fitch Rating’s closed-end fund criteria, is in excess of 100%, and (ii) the Fund’s asset coverage ratios for the Series A MRPS, as calculated in accordance with the Investment Company Act of 1940, as amended (“1940 Act”), is in excess of 225%. The character of distributions to Series A

Aberdeen Asia-Pacific Income Fund, Inc.

32

Notes to Financial Statements (unaudited) (continued)

April 30, 2016

MRPS shareholders made during the fiscal year may differ from their ultimate characterization for federal income tax purposes. For tax purposes, the Fund’s distributions to Series A MRPS shareholders for the six-month period ended April 30, 2016 were 100% net investment income.

h. Federal Income Taxes:

For U.S. federal income purposes, the Fund is comprised of a separately identifiable unit called Qualified Business Unit (“QBU”) (see the Internal Revenue Code of 1986, as amended (“IRC”) section 987). The Fund has operated with a QBU for U.S. federal income purposes since 1990. The home office of the Fund is designated as the United States and of the QBU is Australia with a functional currency of Australian dollar. The securities held within the Fund reside within either the QBU or the home office depending on certain factors including geographic region. As an example, New Zealand and Indonesian securities reside within the Australian QBU. When sold, Australian dollar denominated securities within the Australian QBU generate capital gain/loss (which are translated for U.S. federal income tax purposes into U.S. dollars based on the weighted average exchange rate for the period) but not currency gain/loss. When a New Zealand security is sold within the Australian QBU, the sale generates capital gain/loss as well as currency gain/loss based on the currency exchange between the New Zealand dollar and the Australian dollar.

Currency gain/loss related to currency exchange between the U.S. dollar and the QBU functional currency is generated when money is transferred from a QBU to the home office. The currency gain/loss would result from the difference between the current exchange rate and the fiscal year to date average exchange rate until which profits are utilized and the pooled U.S. dollar basis in the QBU (which is generally computed based on the currency exchange rates from when money was transferred into such QBU and from gain/losses generated within such QBU based on the weighted average exchange rates for the periods such gain/loss was recognized). Based on the QBU structure, there may be sizable differences in the currency gain/loss recognized for U.S. federal income tax purposes and what is reported within the financial statements under GAAP. As of the Fund’s fiscal year-end, the calculation of the composition of distributions to shareholders is finalized and reported in the Fund’s annual report to shareholders.

The Fund intends to continue to qualify as a “regulated investment company” by complying with the provisions available to certain investment companies, as defined in Subchapter M of the IRC, and to make distributions of net investment income and net realized capital gains sufficient to relieve the Fund from all federal income taxes.

Therefore, no federal income tax provision is required. Since tax authorities can examine previously filed tax returns, the Fund’s U.S. federal and state tax returns for each of the four fiscal years up to the most recent fiscal year ended October 31 are subject to such review.

i. Foreign Withholding Tax:

Dividend and interest income from non-U.S. sources received by the Fund are generally subject to non-U.S. withholding taxes. In addition, the Fund may be subject to capital gains tax in certain countries in which it invests. The above taxes may be reduced or eliminated under the terms of applicable U.S. income tax treaties with some of these countries. The Fund accrues such taxes when the related income is earned.

In addition, when the Fund sells securities within certain countries in which it invests, the capital gains realized may be subject to tax. Based on these market requirements and as required under GAAP, the Fund accrues deferred capital gains tax on securities currently held that have unrealized appreciation within these countries. The amount of deferred capital gains tax accrued is reported on the Statement of Operations as part of the Net Change in Unrealized Appreciation/Depreciation on Investments.

j. Cash Flow Information:

The Fund invests in securities and distributes dividends from net investment income and net realized gains on investment and currency transactions which are paid in cash or are reinvested at the discretion of shareholders. These activities are reported in the Statements of Changes in Net Assets and additional information on cash receipts and cash payments is presented in the Statement of Cash Flows. Cash includes domestic and foreign currency but does not include cash at brokers in segregated accounts for financial futures contracts because it is designated as collateral.

3. Agreements and Transactions with Affiliates

a. Investment Manager, Investment Adviser, and Investment Sub-Adviser:

AAMAL serves as investment manager to the Fund, pursuant to a management agreement. Aberdeen Asset Management Limited (the “Investment Adviser”) serves as the investment adviser and Aberdeen Asset Managers Limited (“AAML” or the “Sub-Adviser”) serves as the sub-adviser, pursuant to an advisory agreement and a sub-advisory agreement, respectively. The Investment Manager, the Investment Adviser and the Sub-Adviser are wholly-owned subsidiaries of Aberdeen Asset Management PLC.

Aberdeen Asia-Pacific Income Fund, Inc.

33

Notes to Financial Statements (unaudited) (continued)

April 30, 2016

The Investment Manager makes investment decisions on behalf of the Fund on the basis of recommendations and information furnished to it by the Investment Adviser, including the selection of and the placement of orders with brokers and dealers to execute portfolio transactions on behalf of the Fund. The Sub-Adviser manages the portion of the Fund’s assets that the Investment Manager allocates to it.

The management agreement provides the Investment Manager with a fee, payable monthly by the Fund, at the following annual rates: 0.65% of the Fund’s average weekly Managed Assets up to $200 million, 0.60% of Managed Assets between $200 million and $500 million, 0.55% of Managed Assets between $500 million and $900 million, 0.50% of Managed Assets between $900 million and $1.75 billion and 0.45% of Managed Assets in excess of $1.75 billion. Managed Assets is defined in the management agreement to mean total assets of the Fund, including any form of investment leverage, minus all accrued expenses incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, (iii) the reinvestment of collateral received for securities loaned in accordance with the Fund’s investment objectives and policies, and/or (iv) any other means.

For the six-month period ended April 30, 2016, AAMAL earned $5,278,940 from the Fund for investment management fees.

b. Fund Administration:

Aberdeen Asset Management Inc. (“AAMI”), an affiliate of the Investment Manager, Investment Adviser and Sub-Adviser, is the Fund’s Administrator, pursuant to an agreement under which AAMI receives a fee, payable monthly by the Fund, at an annual fee rate of 0.125% of the Fund’s average weekly Managed Assets up to $1 billion, 0.10% of the Fund’s average weekly Managed Assets between $1 billion and $2 billion, and 0.075% of the Fund’s average weekly Managed Assets in excess of $2 billion. For the six-month period ended April 30, 2016, AAMI earned $1,111,582 from the Fund for administration fees.

c. Investor Relations:

Under the terms of the Investor Relations Services Agreement, AAMI provides and pays third parties to provide investor relations services to the Fund and certain other funds advised by AAMAL or its affiliates as part of an Investor Relations Program. Under the Investor Relations Services Agreement, the Fund owes a portion of the fees

related to the Investor Relations Program (the “Fund’s Portion”). However, investor relations services fees are capped by AAMI so that the Fund will only pay up to an annual rate of 0.05% of the Fund’s average weekly net assets. Any difference between the capped rate of 0.05% of the Fund’s average weekly net assets and the Fund’s Portion is paid for by AAMI.

Pursuant to the terms of the Investor Relations Services Agreement, AAMI provides, among other things, objective and timely information to shareholders based on publicly-available information; provides information efficiently through the use of technology while offering shareholders immediate access to knowledgeable investor relations representatives; develops and maintains effective communications with investment professionals from a wide variety of firms; creates and maintains investor relations communication materials such as fund manager interviews, films and webcasts, published white papers, magazine articles and other relevant materials discussing the Fund’s investment results, portfolio positioning and outlook; develops and maintains effective communications with large institutional shareholders; responds to specific shareholder questions; and reports activities and results to the Board and management detailing insight into general shareholder sentiment.

During the six-month period ended April 30, 2016, the Fund incurred investor relations fees of approximately $259,364. For the six-month period ended April 30, 2016 AAMI did not waive any investor relations fees because the Fund did not reach the capped amount. Investor relations fees and expenses in the Statement of Operations include certain out-of-pocket expenses.

4. Investment Transactions

Purchases and sales of investment securities (excluding short-term securities) for the six-month period ended April 30, 2016, were $363,300,149 and $410,168,990, respectively.

5. Capital

The authorized capital of the Fund is 400 million shares of $0.01 par value common stock. During the six-month period ended April 30, 2016, the Fund repurchased 1,676,887 shares pursuant to its Open Market Repurchase Program, see Note 6 for further information. As of April 30, 2016, there were 254,632,251 shares of common stock issued and outstanding.

6. Open Market Repurchase Program

On March 1, 2001, the Board approved a stock repurchase program. The Board amended the program on December 12, 2007. The stock repurchase program allows the Fund to repurchase up to 10% of its outstanding common stock in the open market during any 12-month

April 30, 2016

period. The Fund reports repurchase activity on the Fund’s website on a monthly basis.

For the six-month period ended April 30, 2016 and fiscal year ended October 31, 2015, the Fund repurchased 1,676,887 and 4,991,465 shares, respectively, through this program.

7. Preferred Shares

At April 30, 2016, the Fund had 2,000,000 shares of Series A MRPS outstanding with an aggregate liquidation preference of $50,000,000 ($25.00 per share). The following table shows the mandatory redemption date, annual fixed rate, aggregate liquidation preference and estimated fair value of the Series A MRPS at April 30, 2016.

Mandatory Redemption Date |  |  | Annual Fixed Rate |  |  | Aggregate Liquidation Preference |  |  | Estimated Fair Value |
| June 27, 2023 |  |  |  | 4.125 | % |  | $ | 50,000,000 |  |  | $ | 50,473,800 |

Holders of the Series A MRPS are entitled to receive quarterly cumulative cash dividend payments on the first business day following each calendar quarter at an annual fixed rate of 4.125% until maturity. The Series A MRPS were issued in private placement offerings to institutional investors and are not listed on any exchange or automated quotation system. Distributions are accrued daily and paid quarterly and are presented in the Statement of Assets and Liabilities as a dividend payable to preferred shareholders. For the six-month period ended April 30, 2016, the Fund paid $962,497 in distributions to preferred shareholders.

The Series A MRPS rank senior to all of the Fund’s outstanding shares of common stock and on a parity with shares of any other series of preferred stock as to the payment of dividends to which the shares are entitled and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Fund.

The estimated fair value of Series A MRPS was calculated, for disclosure purposes, by discounting future cash flows by a rate equal to the current U.S. Treasury rate with an equivalent maturity date, plus the spread between the U.S. insurance and financial debt rate and the U.S. Treasury rate plus a market spread for the issuance of preferred shares.

The Series A MRPS are redeemable in certain circumstances at the option of the Fund. The Series A MRPS are also subject to mandatory redemption, unless otherwise prohibited by the 1940 Act, if the Fund fails to maintain (1) asset coverage, as determined in accordance with Section 18(h) of the 1940 Act, of at least 225%, with respect to all outstanding preferred stock, as of the last day of any month or (2) eligible assets with an aggregate agency discounted value at least

equal to the basic maintenance amount as provided in the Fund’s rating agency guidelines. As of April 30, 2016, the Fund was in compliance with the asset coverage and basic maintenance requirements of the Series A MRPS.

Except for matters which do not require the vote of the holders of the Series A MRPS under the 1940 Act and except as otherwise provided in the Fund’s Charter or Bylaws, or as otherwise required by applicable law, holders of the Series A MRPS have one vote per share and generally vote together with holders of common stock as a single class on all matters submitted to the Fund’s stockholders. The holders of the Series A MRPS, voting separately as a single class, have the right to elect at least two directors of the Fund.

8. Senior Secured Notes

At April 30, 2016, the Fund had $200,000,000 in aggregate principal amount of senior secured notes rated ‘AAA’ by Fitch Ratings outstanding ($100,000,000 in 3.05% Series A Senior Secured Notes due June 12, 2020 and $100,000,000 in 3.69% Series B Senior Secured Notes due June 12, 2023) (collectively, the “Notes”). The Notes are secured obligations of the Fund and, upon liquidation, dissolution or winding up of the Fund, will rank senior to all unsecured and unsubordinated indebtedness and senior to any common or preferred stock pari passu in priority and security with all other secured indebtedness. Holders of the Notes are entitled to receive cash interest payments semi-annually until maturity. The Series A Notes and the Series B Notes accrue interest at annual fixed rates of 3.05% and 3.69%, respectively.

The Notes were issued in private placement offerings to institutional investors and are not listed on any exchange or automated quotation system.

The Notes may be prepaid in certain limited circumstances at the option of the Fund. The Notes are also subject to optional prepayment to the extent needed to satisfy certain requirements if the Fund fails to meet an asset coverage ratio required by the terms of the Notes and is not able to cure the coverage deficiency by the applicable deadline.

The estimated fair value of each series of fixed-rate Notes was calculated, for disclosure purposes, by discounting future cash flows by a rate equal to the current U.S. Treasury rate with an equivalent maturity date, plus either 1) the spread between the interest rate on recently issued debt and the U.S. Treasury rate with a similar maturity date or 2) if there has not been a recent debt issuance, the spread between the AAA corporate finance debt rate and the U.S. Treasury rate with an equivalent maturity date. The following table shows the maturity date, interest rate, notional/carrying amount and

Notes to Financial Statements (unaudited) (continued)

estimated fair value for each series of Notes outstanding at April 30, 2016.

Series |  |  | Maturity Date |  |  | Interest Rate |  |  | Notional/ Carrying Amount |  |  | Estimated Fair Value |
| Series A |  |  |  | June 12, 2020 |  |  |  | 3.05 | % |  | $ | 100,000,000 |  |  | $ | 100,392,290 |
| Series B |  |  |  | June 12, 2023 |  |  |  | 3.69 | % |  | $ | 100,000,000 |  |  | $ | 101,982,242 |

9. Credit Facility

On April 9, 2014, the Fund renewed its credit agreement providing for a $150,000,000 senior secured revolving credit loan facility (the “Revolving Credit Facility”) with a syndicate of banks with Bank of America Merrill Lynch, N.A., acting as administrative agent. On June 12, 2013 the Fund entered into a term loan agreement (the “Term Loan Agreement”) providing for $200,000,000 of senior secured term loans (the “Term Loan Facility”) from Bank of America, N.A. At April 30, 2016 the Fund had $125,000,000 outstanding under the Revolving Credit Facility and $200,000,000 outstanding under the Term Loan Facility. Under the terms of the Revolving Credit Facility and the Term Loan Agreement and applicable regulations, the Fund is required to maintain certain asset coverage ratios for the amount of its outstanding borrowings.

For the six-month period ended April 30, 2016, the average interest rate on the Revolving Credit Facility was 1.38% and the average balance of the Revolving Credit Facility was $125,000,000. Pursuant to the Term Loan Agreement, the Term Loan Facility consists of two separate facilities: $100,000,000 term loan facility which accrues interest at 2.80% per annum (the “Term A Facility”) and a $100,000,000 term loan facility which accrues interest at 2.33% per annum (the “Term B Facility”). For the six-month period ended April 30, 2016, the average interest rate on the Term Loan Facility was 2.57% and the average balance of the Term Loan Facility was $200,000,000. The interest expense is accrued on a daily basis and is payable on a monthly basis or on the last date of the respective LIBOR period, as applicable, for the Revolving Credit Facility, and payable on the last business day of each March, June, September and December and the maturity date for the Term Loan Facility.

The estimated fair value of each Term Loan Facility was calculated, for disclosure purposes, by discounting future cash flows by a rate equal to the current U.S. Treasury rate with an equivalent maturity date, the spread between the U.S. insurance and financial debt rate and the U.S. Treasury rate. The following table shows the maturity

date, interest rate, notional/carrying amount and estimated fair value for each Term Loan Facility outstanding as of April 30, 2016.

Series |  |  | Maturity Date |  |  | Interest Rate |  |  | Notional/ Carrying Amount |  |  | Estimated Fair Value |
| Term A Facility |  |  |  | June 12, 2018 |  |  |  | 2.80 | % |  | $ | 100,000,000 |  |  | $ | 100,614,048 |
| Term B Facility |  |  |  | December 14, 2019 |  |  |  | 2.38 | % |  | $ | 100,000,000 |  |  | $ | 98,511,676 |

The Revolving Credit Facility has a term of 3-years and is not a perpetual form of leverage; there can be no assurance that the Revolving Credit Facility will be available for renewal on acceptable terms, if at all. The Term A Facility and the Term B Facility have 5- and 3-year terms, respectively. Bank loan fees and expenses included in the Statement of Operations include fees for the renewal of the Revolving Credit Facility as well as commitment fees for any portion of the loan facility not drawn upon at any time during the period.

The estimated fair value of the Revolving Credit Facility was calculated, for disclosure purposes, by discounting future cash flows by a rate equal to the current U.S. Treasury rate with an equivalent maturity date, the spread between the U.S. insurance and financial debt rate and the U.S. Treasury rate. The following table shows the maturity date, interest rate, notional/carrying amount and estimated fair value outstanding as of April 30, 2016.

Maturity Date |  |  | Interest Rate |  |  | Notional/ Carrying Amount |  |  | Estimated Fair Value |
| April 9, 2017 |  |  |  | 1.46 | % |  | $ | 125,000,000 |  |  | $ | 124,023,505 |

10. Risks of Leveraged Capital Structure

The amounts borrowed under the Revolving Credit Facility, the Term Loan Facility and the Notes and other funds obtained through various forms of leverage, including the Series A MRPS, may be invested to return higher rates than the rates pursuant to which interests or dividends are paid under such forms of leverage. 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.

Aberdeen Asia-Pacific Income Fund, Inc.

36

Notes to Financial Statements (unaudited) (continued)

April 30, 2016

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 Revolving Credit Facility, the Term Loan Facility and the Notes 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 limited in its ability to declare dividends or other distributions under the terms of the various forms of leverage. In the event of an event of default under either the Revolving Credit Facility or Term Loan Facility, the lenders have 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 lenders may be able to control the liquidation as well. In the event of an event of default under the Note Purchase Agreement, the holders of the Notes have the right to cause a liquidation of the collateral (i.e., sell portfolio securities and other assets of the Fund).

Each of the Revolving Credit Facility Agreement, the Term Loan Agreement, the Note Purchase Agreement or the Securities Purchase Agreement relating to the Series A MRPS includes usual and customary covenants for the applicable 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 Sub-Adviser from fully managing the Fund’s portfolio in accordance with the Fund’s investment objective and policies. Furthermore, non-compliance with such covenants or the occurrence of other events could lead to the cancellation of any and/or all of the forms of leverage. As of April 30, 2016, the Fund was in compliance with all covenants under the agreements relating to the various forms of leverage.

During the six-month period ended April 30, 2016, the Fund incurred fees of approximately $363,995 for the Revolving Credit Facility, Term Loan Facility and Notes.

11. Portfolio Investment Risks

a. Credit and Market Risk:

A debt instrument’s price depends, in part, on the credit quality of the issuer, borrower, counterparty, or underlying collateral and can decline in response to changes in the financial condition of the issuer, borrower, counterparty, or underlying collateral, or changes in specific or general market, economic, industry, political, regulatory, geopolitical, or other conditions. Funds that invest in high yield and emerging market instruments are subject to certain additional credit

and market risks. The yields of high yield and emerging market debt obligations reflect, among other things, perceived credit risk. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk of not receiving timely and/or ultimate payment of interest and principal, greater market price volatility, and less liquid secondary market trading.

b. Interest Rate Risk:

The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Generally, the Fund’s fixed income securities will decrease in value if interest rates rise and vice versa, and the volatility of lower-rated securities is even greater than that of higher-rated securities. Also, longer-term securities are generally more volatile, so the average maturity or duration of these securities affects risk.

The Fund may be subject to a greater risk of rising interest rates due to current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives.

c. Risks Associated with Foreign Securities and Currencies:

Investments in securities of foreign issuers carry certain risks not ordinarily associated with investments in securities of U.S. issuers. These risks include future political and economic developments, and the possible imposition of exchange controls or other foreign governmental laws and restrictions. In addition, with respect to certain countries, there is the possibility of expropriation of assets, confiscatory taxation, and political or social instability or diplomatic developments, which could adversely affect investments in those countries.

Certain countries also may impose substantial restrictions on investments in their capital markets by foreign entities, including restrictions on investments in issuers of industries deemed sensitive to relevant national interests. These factors may limit the investment opportunities available and result in a lack of liquidity and high price volatility with respect to securities of issuers from developing countries.

d. Focus Risk:

The Fund may have elements of risk not typically associated with investments in the United States due to focused investments in a limited number of countries or regions subject to foreign securities or currencies risks. Such focused investments may subject the Fund to additional risks resulting from political or economic conditions in

Aberdeen Asia-Pacific Income Fund, Inc.

37

Notes to Financial Statements (unaudited) (concluded)

April 30, 2016

such countries or regions and the possible imposition of adverse governmental laws or currency exchange restrictions could cause the securities and their markets to be less liquid and their prices to be more volatile than those of comparable U.S. securities.

e. Risks Associated with Mortgage-backed Securities:

The value of mortgage-backed securities can fall if the owners of the underlying mortgages default or pay off their mortgages sooner than expected, which could happen when interest rates fall.

12. Contingencies

In the normal course of business, the Fund may provide general indemnifications pursuant to certain contracts and organizational documents. The Fund’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund, and therefore, cannot be estimated; however, based on experience, the risk of loss from such claims is considered remote.

13. Tax Information

The U.S. federal income tax basis of the Fund’s investments and the net unrealized appreciation as of April 30, 2016 were as follows:

Tax Basis of Investments |  |  | Appreciation |  |  | Depreciation |  |  | Net Unrealized Depreciation |
| $1,893,504,588 |  |  | $ | 62,912,930 |  |  | $ | (15,446,184 | ) |  | $ | 47,466,746 |

14. Subsequent Events

Management has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. Based on this evaluation, no disclosures or adjustments were required to the financial statements as of April 30, 2016, other than those listed below.

On May 10, 2016 and June 9, 2016, the Fund announced that it will pay on May 27, 2016 and June 27, 2016, a distribution of US $0.035 per share to all shareholders of record as of May 19, 2016 and June 20, 2016, respectively.

Effective July 31, 2016, the Fund’s blended benchmark will change, as summarized below:

Index |  | Current Weight |  |  | New Index |  | New Weight |
Bloomberg Ausbond Composite 1 Index |  |  | 45.00% |  |  | Bloomberg Ausbond Composite Index 1 |  |  | 35.00% |
JP Morgan Asian Credit Index 2 |  |  | 35.75% |  |  | JP Morgan Asian Credit Index 2 |  |  | 40.00% |
Markit iBoxx Asia ex Japan Government Bond Index 3 |  |  | 19.25% |  |  | Markit iBoxx Asia Government Index 3 |  |  | 15.00% |
|  |  |  |  |  | Markit iBoxx Asia Government India Index 4 |  |  | 5.00% |
|  |  |  |  |  | Markit iBoxx Asia Government Indonesia Index 5 |  |  | 5.00% |

1 |  | The Bloomberg AusBond Composite Bond Index includes investment grade fixed interest bonds of all maturities issued in the Australian debt market under Australian law.

2 |  | The JP Morgan Asian Credit Index is a broad-based securities market index which consists of liquid US dollar-denominated debt securities issued out of Asia ex-Japan region.

3 |  | The Markit iBoxx Asia Government Index is a subset of the iBoxx Asia ex-Japan Index family investing in local currency sovereign bonds from China, Hong Kong, India, Indonesia, Korea, Malaysia, Philippines, Singapore, Taiwan, and Thailand.

Closed-end funds are traded on the secondary market through one of the stock exchanges. The Fund’s investment return and principal value will fluctuate so that an investor’s shares may be worth more or less than the original cost. Shares of closed-end funds may trade above (a premium) or below (a discount) the net asset value (NAV) of the fund’s portfolio. There is no assurance that the Fund will achieve its investment objective. Past performance does not guarantee future results. Foreign securities are more volatile, harder to price and less liquid than U.S. securities. They are subject to different accounting and regulatory standards, and political and economic risks. These risks may be enhanced in emerging market countries. Concentrating investments in the Asia-Pacific region subjects the fund to more volatility and greater risk of loss than geographically diverse funds.
