example, some foreign exchanges are principal markets so that no common clearing facility exists and an investor may look only to the broker for performance of the contract. In addition, any profits the Fund might realize in trading could be eliminated by adverse changes in the exchange rate, or the Fund could incur losses as a result of those changes. Transactions on foreign exchanges may include both underlying assets which are traded on U.S. commodities exchanges and those which are not. Unlike trading on U.S. exchanges, trading on foreign commodities exchanges is not regulated by the Commodity Futures Trading Commission (“CFTC”).

purchase or sale transaction, subject to the continued availability of a liquid secondary market, which is the purchase or sale of an option of the same type (i.e., the same exercise price and expiration date) as the option previously purchased or sold. The difference between the premiums paid and received represents the Fund’s profit or loss on the transaction. Options on futures contracts that are written or purchased by the Fund on U.S. exchanges are traded on the same contract market as the underlying futures contract, and, like futures contracts, are subject to regulation by the CFTC and the performance guarantee of the exchange clearinghouse.

underperform the market or other funds with similar investment objectives. Additionally, there can be no assurance that all of the personnel of the Advisers will continue to be associated with the Advisers for any length of time. The loss of the services of one or more key employees of the Advisers could have an adverse impact on the Fund's ability to realize its investment objective.

funds. Additional risks associated with investments in China and Hong Kong include exposure to currency fluctuations, less liquidity, expropriation, confiscatory taxation, nationalization, exchange control regulations (including currency blockage) and differing legal standards. Any spread of an infectious illness, public health threat or similar issue could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and generally have a significant impact on the Chinese economy, which in turn could adversely affect the Fund’s investments.

considerable volatility and has historically been subject to relatively frequent and extensive trading halts and suspensions. These trading halts and suspensions have, among other things, contributed to uncertainty in the markets and reduced the liquidity of the securities subject to such trading halts and suspensions, which could include securities held by the Fund.

Investments made through Bond Connect are subject to order, clearance and settlement procedures that are relatively untested in the PRC, which could pose risks to a Fund. A Fund's investments in securities via Bond Connect are generally subject to Chinese securities regulations and listing rules, among other restrictions. Such securities may lose their eligibility at any time, in which case they could be sold but could no longer be purchased through Bond Connect. The Bond Connect program is a relatively new program and may be subject to further interpretation and guidance.

Further, any changes in the Chinese economy, trade regulations, or control over Hong Kong may have an adverse impact on Hong Kong's economy and thereby impact the Fund.

leverage were not used. Interest on borrowings may be at a fixed or floating rate, and the interest at a floating rate generally will be based on short-term rates. The costs associated with the Fund's use of leverage, including the issuance of such leverage and the payment of dividends or interest on such leverage, will be borne entirely by the holders of common stock. As long as the rate of return, net of applicable Fund expenses, on the Fund's investment portfolio investments purchased with leverage exceeds the costs associated with such leverage, the Fund will generate more return or income than will be needed to pay such costs. In this event, the excess will be available to pay higher dividends to holders of common stock. Conversely, if the Fund's return on such assets is less than the cost of leverage and other Fund expenses, the return to the holders of the common stock will diminish. To the extent that the Fund uses leverage, the net asset value and market price of the common stock and the yield to holders of common stock will be more volatile. The Fund's leveraging strategy may not be successful.

Investments in floating rate debt instruments, although generally less sensitive to interest rate changes than longer duration fixed rate instruments, may nevertheless decline in value in response to rising interest rates if, for example, the rates at which they pay interest do not rise as much, or as quickly, as market interest rates in general. Conversely, floating rate instruments will not generally increase in value if interest rates decline. Inverse floating rate debt securities may also exhibit greater price volatility than a fixed rate debt obligation with similar credit quality. To the extent the Fund holds floating rate instruments, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities and the net asset value of the Fund's Common Shares.

the registration statement prepared by the issuer is materially inaccurate or misleading. Private placements typically are subject to restrictions on resale as a matter of contract or under federal securities laws. Because there may be relatively few potential purchasers for such securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund could find it more difficult to sell such securities when it may be advisable to do so or it may be able to sell such securities only at prices lower than if such securities were more widely held. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund's net asset value NAV due to the absence of a trading market.

measured in U.S. dollars, may be affected favorably or unfavorably by changes in currency exchange rates and in exchange control regulations. The Fund may incur costs in connection with conversions between various currencies.

markets may be more affected by the performance of such industries or sectors. Emerging market economies may be based on only a few industries and securities markets that trade a small number of securities. Securities issued by companies or governments located in emerging market countries tend to be especially volatile (particularly during market closures due to local market holidays or other reasons) and may be less liquid than securities traded in developed countries. Securities in these countries have been characterized by greater potential loss than securities of companies and governments located in developed countries. Investments in the securities of issuers located in emerging markets could be affected by risks associated with expropriation and/or nationalization, political or social instability, pervasiveness of corruption and crime, armed conflict, the impact on the economy of civil war, religious or ethnic unrest and the withdrawal or non-renewal of any license enabling the Fund to trade in securities of a particular country, confiscatory taxation, restrictions on transfers of assets, lack of uniform accounting and auditing standards, less publicly available financial and other information, diplomatic development which could affect U.S. investments in those countries, and potential difficulties in enforcing contractual obligations. International trade barriers or economic sanctions against foreign countries, organizations, entities and/or individuals in response to geopolitical tensions or conflicts may adversely affect the value of the Fund's foreign holdings. The type and severity of sanctions and other similar measures are difficult to measure or predict. Emerging market countries generally have less developed legal, accounting and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Moreover, it can be more difficult for investors to bring litigation or enforce judgments against issuers in emerging markets or for U.S. regulators to bring enforcement actions against such issuers.

on market conditions, prices and yields of securities in the Fund's portfolio. Moreover, the economies of developing and emerging market countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These economies also have been and may continue to be adversely affected by economic conditions in the countries with which they trade. Many developing and emerging market economies are considered to be more politically volatile than the developed markets. Investments in securities of issuers in countries other than the U.S. may involve greater political risk, including in some countries, the possibility of nationalization of assets, expropriation or confiscatory taxation, restrictions on repatriation, and the establishment of foreign exchange controls, political changes, government regulation, overburdened and obsolete or unseasoned financial systems, environmental problems, less developed legal systems, economic or social instability or diplomatic developments (including war) which could affect adversely the economies of such countries or the value of the Fund's investments in those countries. Central authorities also tend to exercise a high degree of control over the economies and in many cases have ownership over core productive assets.

unemployment. The issuer or governmental authority that controls the repayment of a developing and emerging market country's debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of such debt. A debtor's willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation and, in the case of a government debtor, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the government debtor's policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. Government debtors may default on their debt and may also be dependent on expected disbursements from foreign governments, multilateral agencies and others abroad to reduce principal and interest arrearages on their debt. The commitment on the part of these governments, agencies and others to make such disbursements may be conditioned on a debtor's implementation of economic reforms and/or economic performance and the timely service of such debtor's obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties' commitments to lend funds to the government debtor, which may further impair such debtor's ability or willingness to service its debts on a timely basis. Holders of government debt, including the Fund, may be requested to participate in the rescheduling of such debt and to extend further loans to government debtors.

obtaining new credit to finance interest payments. Holders of certain foreign government debt securities may be requested to participate in the restructuring of such obligations and to extend further loans to their issuers. There can be no assurance that the foreign government debt securities in which the Fund may invest will not be subject to similar restructuring arrangements or to requests for new credit, which may adversely affect the Fund's holdings. Furthermore, certain participants in the secondary market for such debt may be directly involved in negotiating the terms of these arrangements and may therefore have access to information not available to other market participants. Investments in developing and emerging market countries' government debt securities involve currency risk. See "Foreign Currency Risk" above.

speculative and issuers of these securities are generally considered to be less financially secure and less able to repay interest and principal than issuers of investment-grade securities. Prices of high-yield bonds tend to be very volatile. These securities are less liquid than investment-grade debt securities and may be difficult to price or sell, particularly in times of negative sentiment toward high-yield securities. The Fund's investments in lower rated securities may involve the following specific risks: greater risk of loss due to default because of the increased likelihood that adverse economic or company specific events will make the issuer unable to pay interest and/or principal when due; wider price fluctuations due to changing interest rates and/or adverse economic and business developments; and greater risk of loss due to declining credit quality.

amount of any other senior securities representing indebtedness when calculating the Fund’s asset coverage ratio or treat all such transactions as derivatives transactions. In addition, under the rule, the Fund is permitted to invest in a security on a when-issued or forward-settling basis, or with a non-standard settlement cycle, and the transaction will be deemed not to involve a senior security (as defined under Section 18(g) of the 1940 Act), provided that, (i) the Fund intends to physically settle the transaction and (ii) the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities Provision”). The Fund may otherwise engage in when-issued, forward-settling and non-standard settlement cycle securities transactions that do not meet the conditions of the Delayed-Settlement Securities Provision so long as the Fund treats any such transaction as a “derivatives transaction” for purposes of compliance with the rule. Furthermore, under the rule, the Fund is permitted to enter into an unfunded commitment agreement, and such unfunded commitment agreement will not be subject to the asset coverage requirements under the 1940 Act, if the Fund reasonably believes, at the time it enters into such agreement, that it will have sufficient cash and cash equivalents to meet its obligations with respect to all such agreements as they come due. These requirements may limit the ability of the Fund to use derivatives, reverse repurchase agreements and similar financing transactions, and other relevant transactions as part of its investment strategies. These requirements may increase the cost of the Fund’s investments and cost of doing business, which could adversely affect investors.

or economic output, result in market closures, travel restrictions or quarantines, and generally have a significant impact on the world economy, which in turn could adversely affect the Fund's investments.

Additionally, issuers of corporate fixed income securities might seek protection under the bankruptcy laws. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund's ability to achieve its investment objective. The Investment Manager will monitor developments and seek to manage the Fund's portfolio in a manner consistent with achieving the Fund's investment objective, but there can be no assurance that it will be successful in doing so.

generally managed in a similar fashion, subject to exceptions to account for particular investment restrictions or policies applicable only to certain accounts, differences in cash flows and account sizes, and similar factors; and (ii) portfolio manager personal trading is monitored to avoid potential conflicts. In addition, the Advisers have adopted trade allocation procedures that require equitable allocation of trade orders for a particular security among participating accounts.

In addition, the 1940 Act limits the Fund’s ability to enter into certain transactions with certain affiliates of the Advisers. As a result of these restrictions, the Fund may be prohibited from buying or selling any security directly from or to any portfolio company of a fund managed by the Advisers or one of their affiliates. Nonetheless, the Fund may under certain circumstances purchase any such portfolio company’s loans or securities in the secondary market, which could create a conflict for the Advisers between the interests of the Fund and the portfolio company, in that the ability of the Advisers to recommend actions in the best interest of the Fund might be impaired. The 1940 Act also prohibits certain “joint” transactions with certain of the Fund’s affiliates (which could include other abrdn-managed Funds), which could be deemed to include certain types of investments, or restructuring of investments, in the same portfolio company (whether at the same or different times). These limitations may limit the scope of investment opportunities that would otherwise be available to the Fund. The Board has approved policies and procedures reasonably designed to monitor potential conflicts of interest. The Board will review these procedures and any conflicts that may arise. The Advisers or their respective members, officers, directors, employees, principals or affiliates may come into possession of material, non-public information. The possession of such information may limit the ability of the Fund to buy or sell a security or otherwise to participate in an investment opportunity. Situations may occur where the Fund could be disadvantaged because of the investment activities conducted by the Advisers for other clients, and the Advisers will not employ information barriers with regard to its operations on behalf of its registered and private funds, or other accounts. In certain circumstances, employees of the Advisers may serve as board members or in other capacities for portfolio or potential portfolio companies, which could restrict the Fund’s ability to trade in the securities of such companies.

The Fund intends to distribute to shareholders substantially all of its net investment income and to distribute any net realized capital gains at least annually. Net investment income for this purpose is income other than net realized long-term and short-term capital gains net of expenses. Pursuant to the Dividend Reinvestment and Optional Cash Purchase Plan (the “Plan”), shareholders whose shares of common stock are registered in their own names will be deemed to have elected to have all distributions automatically reinvested by Computershare Trust Company N.A. (the “Plan Agent”) in the Fund shares pursuant to the Plan, unless such shareholders elect to receive distributions in cash. Shareholders who elect to receive distributions in cash will receive such distributions paid by check in U.S. Dollars mailed directly to the shareholder by the Plan Agent, as dividend paying agent. In the case of shareholders such as banks, brokers or nominees that hold shares for others who are beneficial owners, the Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by the shareholders as representing the total amount registered in such shareholders’ names and held for the account of beneficial owners that have not elected to receive distributions in cash. Investors that own shares registered in the name of a bank, broker or other nominee should consult with such nominee as to participation in the Plan through such nominee and may be required to have their shares registered in their own names in order to participate in the Plan. Please note that the Fund does not issue certificates so all shares will be registered in book entry form. The Plan Agent serves as agent for the shareholders in administering the Plan. If the Directors of the Fund declare an income dividend or a capital gains distribution payable either in the Fund’s common stock or in cash, nonparticipants in the Plan will receive cash and participants in the Plan will receive common stock, to be issued by the Fund or purchased by the Plan Agent in the open market, as provided below. If the market price per share (plus expected per share fees) on the valuation date equals or exceeds NAV per share on that date, the Fund will issue new shares to participants at NAV; provided, however, that if the NAV is less than 95% of the market price on the valuation date, then such shares will be issued at 95% of the market price. The valuation date will be the payable date for such distribution or dividend or, if that date is not a trading day on the NYSE, the immediately preceding trading date. If NAV exceeds the market price of Fund shares at such time, or if the Fund should declare an income dividend or capital gains distribution payable only in cash, the Plan Agent will, as agent for the participants, buy Fund shares in the open market, on the NYSE or elsewhere, for the participants’ accounts on, or shortly after, the payment date. If, before the Plan Agent has completed its purchases, the market price exceeds the NAV of the Fund share, the average per share purchase price paid by the Plan Agent may exceed the NAV of the Fund’s shares, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund on the dividend payment date. Because of

the foregoing difficulty with respect to open-market purchases, the Plan provides that if the Plan Agent is unable to invest the full dividend amount in open-market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent will cease making open-market purchases and will receive the uninvested portion of the dividend amount in newly issued shares at the close of business on the last purchase date.
