The Korea Fund, Inc. Portfolio Manager’s Report

December 31, 2017 (unaudited)

During the six-month period from July 1, 2017 to December 31, 2017, the MSCI Korea 25/50 Index (Total Return) rose by 6.41% in Korean Won terms and 13.73% in US dollar (USD) terms. The Korean market advanced in the third quarter mainly driven by semiconductor stocks including Samsung Electronics and SK Hynix, on the back of favorable supply-demand dynamics in the memory chip industry. The Information Technology sector saw some reversal in the fourth quarter on concerns about oversupply in NAND flash memory chips in 2018. Nonetheless, the Korean market found support from the consumer sector on hopes that China would ease some of its retaliation measures in response to Korea’s decision to adopt the THAAD (Terminal High Altitude Area Defense) missile defense system.

Since stepping into office, President Moon’s policies have proven to be more populistic than expected, with an apparent objective to benefit ordinary people at the expense of big corporates and the wealthy. These policies have come in the form of pricing pressure for sectors such as telecom, health insurance and banks. In addition, the accelerated hikes in minimum wages and higher corporate taxes are likely to put pressures on corporate profitability going forward. The Korean government also introduced a new set of property market cooling measures, including lower loan-to-value (LTV) and debt-to-income (DTI) ratios, as well as punitive capital gains tax for multiple-home owners. The measures were more draconian than expected and hurt sentiment for the property sector.

On the geopolitical front, North Korea has increased the frequency of its missile tests including its recent sixth nuclear test. Hostile responses from the US and China, and the concerns over the stability of North Korea’s regime have complicated the geopolitical dynamics in the region. While the risk of war seems low, if it happens the consequence could be disastrous for the Korean markets.

In response to North Korea’s nuclear threat, South Korea has decided to adopt the THAAD missile defense system, which in turn has upset China. Chinese tourists to Korea fell sharply after the Chinese government imposed policy restrictions on group travel to Korea. Korea’s tourism industry, including cosmetics companies and duty free stores, took the biggest hit. Businesses within China have been negatively affected as well. Sales of Korean autos declined dramatically, while some retailers have begun to shut down their stores in China.

The technology sector has been a major driver behind export growth and equity market performance, supported by a strong memory semiconductor cyclical upturn and new mobile phone model launches. Although we expect supply discipline in the memory chip sector should continue, we are mindful of potential downside risks to demand given the recent weakness in smartphone sales.

Fund’s Performance

From July 1, 2017 to December 31, 2017, the total return of The Korea Fund, Inc.’s (the “Fund”) Net Asset Value (NAV) was 13.78% (net of fees) in USD terms, and was in line with the Fund’s benchmark, the MSCI Korea 25/50 Index (Total Return), which returned 13.73% during the same period.

Performance Attribution Review

Positive contributors over the reporting period include ING Life Insurance Korea, which outperformed on the back of stronger than expected earnings with high dividend payouts. We believe the company’s well managed balance sheet allows it to seek faster growth relative to its peers. SK Hynix, one of the world’s largest memory chip makers, was another contributor to performance. The company saw a substantial improvement in earnings thanks to tight supply-demand balance in the memory semiconductor industry. The overweight position in E-Mart, one of the largest discount store chains in Korea, also helped, with the company making solid progress in its new channel strategies such as E-Mart Traders, a bulk wholesaler and retailer, and E-Mart’s online shopping platform.

Our underweight positioning in the health care sector detracted from the Fund’s performance. Progress made by Korean biosimilar companies in developed markets helped drive the sector’s strong performance. In addition, in November the government announced initiatives to boost investments in the KOSDAQ market, which resulted in sharp outperformance of the larger cap biotech stocks in the KOSDAQ index. In the meantime our stock selection in the materials sector also detracted from performance. Rising oil prices, coupled with increased capacity in the US, led to concerns that Korean chemical companies may see margin pressure in 2018.

Outlook

Geopolitical tensions have eased somewhat recently as the Moon government held formal talks with North Korea, and the US agreed to postpone its military exercise in South Korea. However the fundamental problem still seems difficult to resolve, as North Korea is adamant on securing nuclear weapon capabilities, which the US finds unacceptable. Meanwhile, China’s resentment towards the THAAD anti-missile system seems to have cooled down, following President Moon’s visit to China in December 2017. We believe we are passing the worst in Korea-China relations, and gradual improvement is likely in 2018.

We have turned more positive on Korea’s export outlook this year. The US labor market continues to improve and the planned US tax cuts are expected to give the US economy a further boost. Economic data out of Europe also shows an acceleration in growth. A significant part of Korea’s export growth in 2017 was driven by stronger prices, especially in the technology sector. We believe

The Korea Fund, Inc. Portfolio Manager’s Report

December 31, 2017 (unaudited) (continued)

export growth in 2018 will be more volume driven and broad based. However, the implication of stronger economic growth in the equity market is quite uncertain. The benefit to earnings may be offset by faster interest rate increases which tend to put pressure on valuation multiples.

We continue to be concerned about the Korean government’s increased regulatory intervention in the corporate sector. There is now downward pressure on bank lending spreads, insurance premiums and mobile telecom tariffs. If minimum wages continue to rise at the current accelerated rate, it would threaten profit margins in the service sector, particularly the retailers. On the other hand, with the recent Korean government initiatives to support the KOSDAQ market, we may see more Korean stock market movements that are driven by liquidity flows rather than fundamentals. Against this backdrop, we currently expect more attention will be paid to policy risks as we assess company outlook and construct our portfolio.

Postscript

Global equity markets underwent a sharp correction in early February as wage data in the US heightened concerns that inflation may accelerate and push the Federal Reserve to raise interest rates at a faster pace. After a long period of calm, investors were also caught off-guard by the sudden return of market volatility. Looking forward, the Federal Reserve is on track to reverse its quantitative easing program and withdraw liquidity from the system. Meanwhile, the US government seems prepared to boost the economy through tax cuts and higher infrastructure spending, at a time when the global economy is showing signs of stronger growth. Against this backdrop, the risk of higher inflation and bond yields is significant. If long term interest rates rise significantly, the negative impact on equity valuations could more than offset the benefit from stronger earnings. Whilst equity markets will likely recover from the current bout of volatility, we are mindful of the risk that turmoil may return if and when interest rates rise to more treacherous levels in the latter part of the year.

This information is unaudited and is intended for informational purposes only. It is presented only to provide information on investment strategies and opportunities. The Fund seeks long-term capital appreciation through investment in securities, primarily equity securities, of Korean companies. Investing in non-U.S. securities entails additional risks, including political and economic risk and the risk of currency fluctuations, as well as lower liquidity. These risks, which can result in greater price volatility, will generally be enhanced in less diversified funds that concentrate investments in a particular geographic region. The Fund is a closed-end exchange traded management investment company. This material is presented only to provide information and is not intended for trading purposes. Closed-end funds, unlike open-end funds, are not continuously offered. After the initial public offering, shares are sold on the open market through a stock exchange, where shares may trade at a premium or a discount. Holdings are subject to change daily.

The Korea Fund, Inc. Performance & Statistics

December 31, 2017 (unaudited) (continued)

Notes to Performance & Statistics:

(1) Past performance is no guarantee of future results. Total return is calculated by determining the percentage change in NAV or market price (as applicable) in the specified period. The calculation assumes that all dividends and distributions, if any, have been reinvested. Total return does not reflect broker commissions or sales charges in connection with the purchase or sale of Fund shares. Total return for a period of more than one year represents the average annual total return. Total return for a period of less than one year is not annualized.

Performance at market price will differ from results at NAV. Although market price returns typically reflect investment results over time, during shorter periods returns at market price can also be influenced by factors such as changing views about the Fund, market conditions, supply and demand for the Fund’s shares, or changes in the Fund’s dividends.

An investment in the Fund involves risk, including the loss of principal. Total return, market price and NAV will fluctuate with changes in market conditions. This data is provided for information purposes only and is not intended for trading purposes. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and once issued, shares of closed-end funds are traded in the open market through a stock exchange. NAV is equal to total assets less total liabilities divided by the number of shares outstanding. Holdings are subject to change daily.

(2) See Note 8 in the Notes to Financial Statements.

(3) Morgan Stanley Capital International (“MSCI”) Korea Index is a market capitalization-weighted index of equity securities of companies domiciled in Korea. The index is designed to represent the performance of the Korean stock market and excludes certain market segments unavailable to U.S. based investors. The MSCI Korea Index (Total Return) returns assume reinvestment of dividends (net of foreign withholding taxes) while the MSCI Korea Index (Price Return) returns do not and, unlike Fund returns, do not reflect any fees or expenses. Effective July 1, 2017, the Board approved the MSCI Korea 25/50 Index as the primary benchmark for the Fund. The MSCI Korea Index 25/50 is designed to measure the performance of the large and mid cap segments of the Korean market. It applies certain investment limits that are imposed on regulated investment companies, or RICs, under the current US Internal Revenue Code. One requirement of a RIC is that at the end of each quarter of its tax year no more than 25% of the value of the RIC’s assets may be invested in a single issuer and the sum of the weights of all issuers representing more than 5% of the fund should not exceed 50% of the fund’s total assets. The index covers approximately 85% of the free float-adjusted market capitalization in Korea. The returns assume reinvestment of dividends (net of foreign withholding taxes) but do not reflect any fees or expenses. It is not possible to invest directly in an index. Total return for a period of more than one year represents the average annual return. Total return for a period of less than one year is not annualized.

(4) The Korea Composite Stock Price Index (“KOSPI”) is an unmanaged capitalization-weighted index of all common shares on the Stock Market Division of the Korea Exchange (formerly the “Korea Stock Exchange”). The KOSPI returns, unlike Fund returns, do not reflect any fees or expenses. It is not possible to invest directly in an index. Total return for a period of more than one year represents the average annual return. Total return for a period of less than one year is not annualized.

(5) The NAV disclosed in the Fund’s financial statements may differ from this NAV due to accounting principles generally accepted in the United States of America.

The Korea Fund, Inc. Notes to Financial Statements

December 31, 2017 (unaudited)

1. Organization and Significant Accounting Policies

The Korea Fund, Inc. (the “Fund”) is registered under the Investment Company Act of 1940 and the rules and regulations thereunder, as amended, as a closed-end, non-diversified management investment company organized as a Maryland corporation, and accordingly, follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 Financial Services—Investment Companies. Allianz Global Investors U.S. LLC (“AllianzGI U.S.” or the “Investment Manager”) serves as the Fund’s investment manager. AllianzGI U.S. is an indirect, wholly-owned subsidiary of Allianz Asset Management of America L.P. (“AAM”). AAM is an indirect, wholly-owned subsidiary of Allianz SE, a publicly traded European insurance and financial services company. The Fund has authorized 200 million shares of common stock with $0.01 par value.

The Fund’s investment objective is to seek long-term capital appreciation through investment in securities, primarily equity securities, of Korean companies. There can be no assurance that the Fund will meet its stated objective.

The preparation of the Fund’s financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires the Fund’s management to make estimates and assumptions that affect the reported amounts and disclosures in the Fund’s financial statements. Actual results could differ from those estimates.

In the normal course of business, the Fund enters into contracts that contain a variety of representations that provide general indemnifications. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the risk of loss is expected to be remote.

In October 2016, the U.S. Securities and Exchange Commission (“SEC”) adopted new rules and forms, and amendments to certain current rules and forms, to modernize reporting and disclosure of information by registered investment companies. The amendments to Regulation S-X require standardized, enhanced disclosure about derivatives in investment company financial statements, and also change the rules governing the form and content of such financial statements. The amendments to Regulation S-X took effect on August 1, 2017 and the financial statements have been modified accordingly, as applicable.

The following is a summary of significant accounting policies consistently followed by the Fund:

(a) Valuation of Investments

Portfolio securities and other financial instruments for which market quotations are readily available are stated at market value. Market value is generally determined on the basis of official closing prices, last reported sales prices, or if no sales or closing prices are reported, on the basis of quotes obtained from a quotation reporting system, established market makers, or independent pricing services. Investments in mutual funds are valued at the net asset value per share (“NAV”) as reported on each business day.

Portfolio securities and other financial instruments for which market quotations are not readily available, or for which a development/event occurs that may significantly impact the value of a security, are fair-valued, in good faith, pursuant to procedures established by the Board of Directors (the “Board”) of the Fund, or persons acting at their discretion pursuant to procedures established by the Board. The Fund’s investments are valued daily and the Fund’s NAV is calculated as of the close of regular trading (normally 4:00 p.m. Eastern Time) on the New York Stock Exchange (“NYSE”) on each day the NYSE is open for business using prices supplied by an independent pricing service or broker/dealer quotations, or by using the last sale or settlement price on the exchange that is the primary market for such securities, or the mean between the last bid and ask quotations. In unusual circumstances, the Board may determine the NAV as of 4:00 p.m., Eastern Time, notwithstanding an earlier, unscheduled close or halt of trading on the NYSE. For foreign equity securities (with certain exceptions, if any), the Fund fair values its securities daily using modeling tools provided by a statistical research service. This service utilizes statistics and programs based on historical performance of markets and other economic data (which may include changes in the value of U.S. securities or security indices).

Short-term debt instruments maturing in 60 days or less are valued at amortized cost, if their original term to maturity was 60 days or less, or by amortizing premium or discount based on their value on the 61^st day prior to maturity, if the original term to maturity exceeded 60 days.

Investments initially valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from pricing services. As a result, the NAV of the Fund’s shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of securities traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the NYSE is closed. The prices used by the Fund to value securities may differ from the value that would be realized if the securities were sold and these differences could be material to the Fund’s financial statements.

The Korea Fund, Inc. Notes to Financial Statements

December 31, 2017 (unaudited) (continued)

1. Organization and Significant Accounting Policies (continued)

(b) Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants. The three levels of the fair value hierarchy are described below:

• Level 1—quoted prices in active markets for identical investments that the Fund has the ability to access

• Level 2—valuations based on other significant observable inputs, which may include, but are not limited to, quoted prices for similar assets or liabilities, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates or other market corroborated inputs

• Level 3—valuations based on significant unobservable inputs (including the Investment Manager’s or Valuation Committee’s own assumptions and securities whose price was determined by using a single broker’s quote)

The valuation techniques used by the Fund to measure fair value during the six months ended December 31, 2017 were intended to maximize the use of observable inputs and to minimize the use of unobservable inputs.

The Fund’s policy is to recognize transfers between levels at the end of the reporting period. An investment asset’s or liability’s level within the fair value hierarchy is based on the lowest level input, individually or in aggregate, that is significant to the fair value measurement. The objective of fair value measurement remains the same even when there is a significant decrease in the volume and level of activity for an asset or liability and regardless of the valuation techniques used. Investments categorized as Level 1 or 2 as of period end may have been transferred between Levels 1 and 2 since the prior period due to changes in the valuation method utilized in valuing the investments.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following are certain inputs and techniques that the Fund generally uses to evaluate how to classify each major category of assets and liabilities within Level 2 and Level 3, in accordance with U.S. GAAP.

Equity Securities (Common Stock)—Equity securities traded in inactive markets and certain foreign equity securities are valued using inputs which include broker-dealer quotes, recently executed transactions adjusted for changes in the benchmark index, or evaluated price quotes received from independent pricing services that take into account the integrity of the market sector and issuer, the individual characteristics of the security, and information received from broker-dealers and other market sources pertaining to the issuer or security. To the extent that these inputs are observable, the values of equity securities are categorized as Level 2. To the extent that these inputs are unobservable, the values are categorized as Level 3.

(c) Investment Transactions and Investment Income

Investment transactions are accounted for on the trade date. Realized gains and losses on investments are determined on an identified cost basis. Interest income on uninvested cash is recorded upon receipt. Dividend income is recorded on the ex-dividend date. Korean-based corporations have generally adopted calendar year-ends, and their interim and final corporate actions are normally approved, finalized and announced by their boards of directors and stockholders in the first and third quarters of each calendar year. Generally, estimates of their dividends are accrued on the ex-dividend date principally in the prior December and/or June period ends. These dividend announcements are recorded by the Fund on such ex-dividend dates. Any subsequent adjustments thereto by Korean corporations are recorded when announced. Presently, dividend income from Korean equity investments is earned primarily in the last calendar quarter of each year, and will be received primarily in the first calendar quarter of the following year. Certain other dividends and related withholding taxes, if applicable, from Korean securities may be recorded subsequent to the ex-dividend date as soon as the Fund is informed of such dividends and taxes. Dividend and interest income on the Statement of Operations are shown net of any foreign taxes withheld on income from foreign securities.

(d) Federal Income Taxes

The Fund intends to distribute all of its taxable income and to comply with the other requirements of Subchapter M of the U.S. Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, no provision for U.S. federal income taxes is required. The Fund may be subject to excise tax based on distributions to stockholders.

Accounting for uncertainty in income taxes establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. In accordance with provisions set forth under U.S. GAAP, the Investment Manager has reviewed the Fund’s tax positions for all open tax years.

The Korea Fund, Inc. Notes to Financial Statements

1. Organization and Significant Accounting Policies (continued)

As of December 31, 2017, the Fund has recorded no liability for net unrecognized tax benefits relating to uncertain income tax positions they have taken. The Fund’s federal income tax returns for the prior three years, as applicable, remain subject to examination by the Internal Revenue Service.

(e) Foreign Investment and Exchange Controls in Korea

The Foreign Exchange Transaction Act, the Presidential Decree relating to such Act and the regulations of the Minister of Strategy and Finance (formerly known as Minister of Finance and Economy) issued thereunder impose certain limitations and controls which generally affect foreign investors in Korea. Through August 18, 2005, the Fund had a license from the Ministry of Finance and Economy to invest in Korean securities and to repatriate income received from dividends and interest earned on, and net realized capital gains from, its investments in Korean securities or to repatriate from investment principal up to 10% of the NAV (taken at current value) of the Fund (except upon termination of the Fund, or for expenses in excess of Fund income, in which case the foregoing restriction shall not apply). Under the Foreign Exchange Transaction Act, the Minister of Strategy and Finance has the power, with prior (posterior in case of urgency) public notice of scope and duration, to suspend all or a part of foreign exchange transactions when emergency measures are deemed necessary in case of radical change in the international or domestic economic situation. The Fund could be adversely affected by delays in, or the refusal to grant, any required governmental approval for such transactions.

The Fund relinquished its license from the Korean Ministry of Finance and Economy effective August 19, 2005. The Fund had engaged in negotiations with the Korean Ministry of Finance and Economy concerning the feasibility of the Fund’s license being amended to allow the Fund to repatriate more than 10% of Fund capital. However, the Ministry of Finance and Economy advised the Fund that the license cannot be amended as a result of a change in the Korean regulations. As a result of the relinquishment of the license, the Fund is subject to the Korean securities transaction tax equal to 0.3% of the fair market value of any portfolio securities transferred by the Fund on the Korea Exchange and 0.5% of the fair market value of any portfolio securities transferred outside of the Korea Exchange. The relinquishment did not otherwise affect the Fund’s operations. For the six months ended December 31, 2017, the Fund incurred $415,191 in transaction taxes in connection with portfolio securities transferred by the Fund on the Korea Exchange. Net realized gain on investments on the Statement of Operations is shown net of the transaction taxes incurred by the Fund.

Certain securities held by the Fund may be subject to aggregate or individual foreign ownership limits. These holdings are in industries that are deemed to be of national importance.

(f) Dividends and Distributions

The Fund declares dividends from net investment income and distributions of net realized capital gains, if any, at least annually. The Fund records dividends and distributions on the ex-dividend date. The amount of dividends from net investment income and distributions from net realized capital gains is determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These “book-tax” differences are considered either temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal income tax treatment; temporary differences do not require reclassification. To the extent dividends and/or distributions exceed current and accumulated earnings and profits for federal income tax purposes, they are reported as dividends and/or distributions to stockholders from return of capital.

(g) Foreign Currency Translation

The Fund’s accounting records are maintained in U.S. dollars as follows: (1) the foreign currency market values of investments and other assets and liabilities denominated in foreign currencies are translated at the prevailing exchange rate at the end of the period; and (2) purchases and sales, income and expenses are translated at the prevailing exchange rate on the respective dates of such transactions. The resulting net foreign currency gain (loss) is included in the Fund’s Statement of Operations.

The Fund does not generally isolate that portion of the results of operations arising as a result of changes in foreign currency exchange rates from the fluctuations arising from changes in the market prices of securities. Accordingly, such foreign currency gain (loss) is included in net realized and unrealized gain (loss) on investments. However, the Fund does isolate the effect of fluctuations in foreign currency exchange rates when determining the gain (loss) upon the sale or maturity of foreign currency denominated debt obligations pursuant to U.S. federal income tax regulations; such amount is categorized as foreign currency gain (loss) for both financial reporting and income tax reporting purposes.

At December 31, 2017, the Korean WON/U.S. dollar exchange rate was WON 1,070.55 to U.S. $1.

(h) Securities Lending

The Fund may engage in securities lending. The loans are secured by collateral at least equal, at all times, to the market value of the loaned securities. During the term of the loan, the Fund will continue to receive any dividends or amounts

The Korea Fund, Inc. Notes to Financial Statements

December 31, 2017 (unaudited) (continued)

1. Organization and Significant Accounting Policies (continued)

equivalent thereto, on the loaned securities while receiving a fee from the borrower and/or earning interest on the investment of the cash collateral. Securities lending income is disclosed as such in the Statement of Operations. Income generated from the investment of cash collateral, less negotiated rebate fees paid to borrowers and transaction costs, is allocated between the Fund and securities lending agent. Cash collateral received for securities on loan is invested in securities identified in the Schedule of Investments and the corresponding liability is recognized as such in the Statement of Assets and Liabilities. Loans are subject to termination at the option of the borrower or the Fund.

Upon termination of the loan, the borrower will return to the lender securities identical to the loaned securities. The Fund may pay reasonable finders’, administration and custodial fees in connection with a loan of its securities and may share the interest earned on the collateral with the borrower. The Fund bears the risk of delay in recovery of, or even loss of rights in, the securities loaned should the borrower of the securities fail financially. The Fund also bears the risk of loss in the event the securities purchased with cash collateral depreciate in value.

The Fund did not have any securities on loan at December 31, 2017.

2. Principal Risks

In the normal course of business, the Fund trades financial instruments and enters into financial transactions where risk of potential loss exists due to, among other things, changes in the market (market risk) or failure of the other party to a transaction to perform (counterparty risk). The Fund is also exposed to other risks such as, but not limited to, foreign currency risk.

To the extent the Fund directly invests in foreign currencies or in securities that trade in, and receive revenues in, foreign currencies, or in derivatives that provide exposure to foreign currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including economic growth, inflation, changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or the imposition of currency controls or other political developments in the United States or abroad. As a result, the Fund’s investments in foreign currency-denominated securities may reduce the returns of the Fund. The local emerging market currencies in which the fund may be invested may experience substantially greater volatility against the U.S. dollar than the major convertible currencies in developed countries.

The Fund is subject to elements of risk not typically associated with investments in the U.S., due to concentrated investments in foreign issuers located in a specific country or region. Such concentrations will subject the Fund to additional risks resulting from future political or economic conditions in such country or region and the possible imposition of adverse governmental laws or currency exchange restrictions affecting such country or region, which could cause the securities and their markets to be less liquid and prices more volatile than those of comparable U.S. companies.

The market values of securities may decline due to general market conditions (market risk) which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities and equity-related investments generally have greater market price volatility than fixed income securities, although under certain market conditions fixed income securities may have comparable or greater price volatility. Credit ratings downgrades may also negatively affect securities held by the Fund. Even when markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market. In addition, market risk includes the risk that geopolitical events will disrupt the economy on a national or global level.

The Fund is exposed to counterparty risk, or the risk that an institution or other entity with which the Fund has unsettled or open transactions will default. The potential loss to the Fund could exceed the value of the financial assets recorded in the Fund’s financial statements. Financial assets, which potentially expose the Fund to counterparty risk, consist principally of cash due from counterparties and investments. The Investment Manager seeks to minimize the Fund’s counterparty risk by performing reviews of each counterparty and by minimizing concentration of counterparty risk by undertaking transactions with multiple customers and counterparties on recognized and reputable exchanges. Delivery of securities sold is only made once the Fund has received payment. Payment is made on a purchase once the securities have been delivered by the counterparty. The trade will fail if either party fails to meet its obligation.

3. Investment Manager

The Fund has an Investment Management Agreement (the “Management Agreement”) with the Investment Manager. Subject to the supervision of the Fund’s Board, the Investment Manager is responsible for managing, either directly or through others selected by it, the Fund’s investment activities, business affairs, and other administrative matters. Pursuant to the Management Agreement, the Investment Manager receives an annual fee, payable monthly, at the annual rate of 0.75% of the value of the Fund’s average daily net assets up to $250 million; 0.725% of the next $250 million of average daily net assets; 0.70% of the next $250 million of average daily net assets; 0.675% of the next $250 million of average daily net assets and 0.65% of average daily net assets in excess of $1 billion. For the six months ended December 31, 2017, the Fund paid investment management fees at an effective rate of 0.748% of the Fund’s average daily net assets.

4. Investments in Securities

For the six months ended December 31, 2017, purchases and sales of investments, other than short-term securities were $107,365,321 and $137,865,397, respectively.

5. Income Tax Information

At December 31, 2017, the cost basis of portfolio securities for federal income tax purposes was $161,676,353. Gross unrealized appreciation was $98,013,214; gross unrealized depreciation was $713,783; and net unrealized appreciation was $97,299,431. The difference between book and tax cost basis was attributable to wash sale loss deferrals.

6. Discount Management Program

The Fund has a share repurchase program under which the Fund will repurchase in each twelve month period ended June 30, up to 10% of its common stock outstanding as of the close of business on June 30 the prior year, but will permit shares to be repurchased at differing discount trigger levels that will not be announced. The Fund will repurchase shares at a discount, in accordance with procedures approved by the Board. Subject to these procedures, the timing and amount of any shares repurchased will be determined by the Board and/or its Discount Management Committee in consultation with the Investment Manager.

For the six months ended December 31, 2017, the Fund repurchased 214,540 shares of its common stock on the open market, which represented approximately 4% of the shares outstanding at June 30, 2017 at a total cost, inclusive of commissions ($0.03 per share), of $8,891,324 at a per-share weighted average discount to NAV of 11.07%. For the year ended June 30, 2017, the Fund repurchased 511,796 shares of its common stock on the open market, which represented approximately 7% of the shares outstanding at June 30, 2016 at a total cost, inclusive of commissions ($0.03 per share), of $17,913,838 at a per-share weighted average discount to NAV of 11.85%.

7. Fund Ownership

At December 31, 2017, the City of London Investment Group PLC, Lazard Asset Management LLC, 1607 Capital Partners and the Bill & Melinda Gates Foundation held approximately 37%, 12%, 8% and 6%, respectively, of the Fund’s outstanding shares. Investment activities of these stockholders could have a material impact to the Fund.

8. Fund Shares Issued

On December 22, 2008, the Fund declared a capital gain distribution of $90.30 per share. The distribution was made in newly issued Fund shares, based on the Fund’s market price per share on January 26, 2009 (“Pricing Date”), unless a cash election was made. The total cash distribution was limited to 20% of the aggregate dollar amount of the total distribution (excluding any cash paid in lieu of fractional shares). On January 29, 2009 (the payable date) the Fund issued 8,007,555 shares based on the market price of $21.99 per share on the Pricing Date. NAV total return for periods that include December 2008 and January 2009 had been calculated assuming that this capital gain distribution was paid entirely in newly issued Fund shares priced at the Fund’s NAV at the close of business on the Pricing Date. In addition, the Fund adjusted its NAV on December 31, 2008 for purposes of calculating performance by using the actual number of shares outstanding on such date (excluding any estimate of shares to be issued upon reinvestment).

9. Tender Offer

On April 18, 2017, the Board announced a tender offer to purchase for cash up to 10% of the Fund’s issued and outstanding common stock, at a price equal to 98% of its NAV per share on the tender offer expiration date. The Fund’s tender offer, which commenced on April 26, 2017 and expired on May 23, 2017, was oversubscribed. As a result of the tender offer, the Fund purchased 653,807 shares from stockholders, the maximum number of shares to be purchased, as indicated by the tender offer, at a price of $43.22 per share, for a cost of $28,257,538. The accretion to NAV resulting from the tender offer was $0.10 per share.

22 The Korea Fund, Inc. Semi-Annual Report 12.31.17

The Korea Fund, Inc. Matters Relating to the Directors’ Consideration of the

Investment Management Agreement (unaudited)

The Investment Company Act of 1940 requires that both the full Board of Directors and a majority of the Directors who are not “interested persons” of the Investment Manager and its affiliates (the “Independent Directors”), voting separately, annually approve the continuation of your Fund’s investment management agreement (the “Management Agreement”) with the Investment Manager. Your Fund’s Board is comprised of five Directors, all of whom are Independent Directors. At an in-person meeting held on October 20, 2017, the Board approved the renewal of the Management Agreement at the recommendation of the Board’s Contracts Committee, which is comprised of all five Directors. The Board’s review process and considerations in approving the Management Agreement are set forth below.

Review Process.    The Board of Directors considers matters bearing on your Fund and the Management Agreement at each of its meetings. Specifically, the Board maintains an Investment Committee, comprised of all of the Directors and chaired by an experienced investment professional, to monitor all investment related matters throughout the year. The Board (i) met six times during the past year to discuss Fund matters and at each of the regular quarterly meetings dedicated a substantial amount of time to reviewing portfolio related issues (such time was spent in both executive session and with both senior management of the Investment Manager and the portfolio manager and his team at each regular meeting), and (ii) received extensive information throughout the year, outside of the abovementioned meetings, regarding the management of your Fund, including information regarding various functions performed by the investment team, as well as the Investment Manager’s compliance monitoring and portfolio trading practices. In addition, as an independent, third party aid the Board continues its engagement of Morningstar Associates, LLC (“Morningstar”), a leading US and international provider of fundamentally driven research, to supply input supporting the Board’s ongoing review of both the Fund’s performance as well as the investment performance of a representative peer group. This peer group, currently made up of 14 (for the one, three- and five-year periods) and 13 (for the ten-year period) alternative investment opportunities represents, your Board believes, virtually all publically offered, pooled investment products available for international investors in the Korean equity space whether managed in the U.S. or elsewhere. Whilst your Board considers this peer group to represent the significant funds in the space, it notes that the component funds use varying benchmarks, including the MSCI Korea NR Index (Net Return) (the “MSCI Korea Index”), or more frequently, the Korea Stock Exchange KOSPI Index (the “KOSPI Index”) which have differing effects on the underlying risk free portfolios and hence the investment returns so achieved. The Board approved the MSCI Korea 25/50 Index as the primary benchmark for the Fund, effective July 1, 2017. The Board also considered detailed information from Morningstar concerning the consistency of investment style of the Investment Manager and the risk relative to return of your Fund’s investment portfolio in itself and within the peer group.

In addition to the information the Board received at each quarterly meeting, in connection with its annual contract review, the Board received and relied upon materials provided by the Investment Manager, which included, among other items: (i) data supplied by Thomson Reuters Lipper, Inc. (“Lipper”), a leading third party provider of mutual fund information on the total return investment performance of your Fund over various time periods and the investment performance of a comparative group of international closed-end funds, (ii) information provided by Lipper on your Fund’s management fees and total expenses as well as the management fees and total expenses of a comparative peer group of international closed-end funds, (iii) information regarding the investment performance of comparable market indices, (iv) information regarding the management fees of comparable portfolios of other clients of the Investment Manager and your Fund’s former sub-adviser (the “Former Sub-Adviser”) (as personnel of the Former Sub-Adviser continued to provide services to your Fund as “associated persons” of the Investment Manager), including open-end funds and other clients, (v) the estimated profitability to the Investment Manager from its relationship with your Fund, (vi) descriptions of various administrative functions performed for your Fund by the Investment Manager, and (vii) information regarding the overall organization of the Investment Manager, including information regarding senior management, portfolio managers and other personnel providing investment management, administrative and other services to your Fund. The Board was assisted in its evaluation of the Management Agreement by counsel for your Fund, with whom it met separately from the Investment Manager.

The Directors’ conclusion as to the continuation of the Management Agreement was based on a comprehensive consideration of all information provided to the Board and not the result of any single issue. Some of the factors that figured particularly in the Directors’ deliberations are described below, although individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. It is also important to recognize that the Board’s review of your Fund’s Management Agreement is the result of years of review and discussion, rather than one particular period. The Directors’ conclusions may be based, in part, on their consideration of these arrangements during the course of the year and in prior years.

Nature, Quality and Extent of Services.     The Board considered the terms of the Management Agreement, including the scope of advisory services provided under the Management Agreement. The Board noted that, under the Management Agreement, the Investment Manager provides portfolio management and administrative services to your Fund. The Board also noted that the compliance personnel of the Former Sub-Adviser act as “associated persons” of the Investment Manager and report directly to the Investment Manager’s chief compliance officer. The Board considered the experience and skills of senior management and investment personnel, the resources made available to such

12.31.17 The Korea Fund, Inc. Semi-Annual Report 23

The Korea Fund, Inc. Matters Relating to the Directors’ Consideration of the

Investment Management Agreement (unaudited) (continued)

personnel, the ability of the Investment Manager to attract and retain high-quality personnel, and the organizational depth and stability of the Investment Manager. The Board also considered the quality of the administrative services provided by the Investment Manager and determined these services to be of high quality.

The Board reviewed your Fund’s performance over various periods and compared those returns to various agreed-upon performance measures, including market indices and peer groups compiled by Lipper, Morningstar, and the Board itself.

In the course of these deliberations, the Board took into account information provided by the Investment Manager in connection with the contract review meeting, as well as during investment review meetings conducted with portfolio management personnel during the course of the year regarding your Fund’s performance. The Board observed that, although its own peer group maintained by Morningstar of 13 or 14 (varying for the one-, three-, five- and ten-year periods) comparative investible products in the Korean space was appropriate, there were limitations in the comparative performance data provided by Lipper, given that this peer group also includes Pacific funds (excluding Japan), which are generally not similarly situated to your Fund. In its review of your Fund’s performance against the aforementioned peer group of Korea funds maintained by Morningstar, the Board observed that your Fund’s total return (based on net asset value) performance ranked in the 1st quartile for the one-year period, the 2nd quartile for the three- and five-year periods and the 4th quartile for the ten-year period ended September 30, 2017. The Board also noted that most of the funds in the Morningstar peer group used the KOSPI Index as a benchmark and that the Fund’s primary benchmark, the MSCI Korea Index, had outperformed the KOSPI Index for the one-, three-, and five-year periods and had underperformed the KOSPI Index for the ten-year period. In connection with this review, the Board noted that this Morningstar peer group contains funds both registered under the Investment Company Act of 1940 and entities registered in other jurisdictions that are subject to alternative regulatory regimes than your Fund with differing regulatory investment restrictions and may calculate their performance using differing methodologies, which the Board noted would affect particularly the comparative performance of such entities.

The Board observed that your Fund’s total return performance (based on net asset value) underperformed the MSCI Korea Index for the one-, three-, five- and ten-year periods ended September 30, 2017. The Board further observed that your Fund’s total return performance (based on net asset value) underperformed the KOSPI Index for the one-, three-, five-, and ten-year periods ended September 30, 2017. In addition, the Board noted a higher level of volatility in performance over time among the funds in the peer group assembled by Morningstar, resulting in most such funds having periods of poor performance relative to their peers from time to time.

The Board discussed in detail the overall investment performance of your Fund. The Board discussed the depth of the Fund’s management team and noted the general improvement in the Fund’s performance against its benchmark since the Fund’s portfolio manager had been replaced in 2014.

On the basis of this evaluation, the ongoing review of investment results by the Board in conjunction with the Investment Manager, the Board concluded that the nature, quality and extent of services provided by the Investment Manager was sufficient to support renewal of the Management Agreement.

Fees and Expenses.    The Board considered your Fund’s investment management fee schedule, total expense ratio and comparative information provided by Lipper regarding investment management fee rates paid to other investment advisers by, and total expense ratios of, comparable funds. With respect to management fees paid to other investment advisers by comparable funds, the Board noted that the effective fee rates paid by your Fund were less than the median, and less than the mean, of the four-member peer group compiled by Lipper (based on the management fees paid by your Fund for your Fund’s fiscal year ended June 30, 2017). The Board also considered the management fees charged by the Investment Manager to other clients, including open-end funds, with investment strategies comparable to that of your Fund, and noted that the management fees paid by your Fund, with few exceptions, were generally lower than the fees paid by such other clients of the Investment Manager. The Board noted that your Fund’s total operating expenses were less than both the median and the mean of the four-member peer group compiled by Lipper (based on the operating expenses for your Fund’s fiscal year ended June 30, 2017).

The Board noted that, because your Fund is closed-end and does not make a continuous offering of its securities, your Fund’s size is relatively static and it would be unlikely that economies of scale will result from your Fund’s growth other than through capital gain, which itself is a number monitored closely by the Board. The Board noted its option to reconsider the management fee breakpoint levels in the future if your Fund’s assets grow substantially or should there be an opportunity to raise new assets.

On the basis of the information provided, the Board concluded that management fee was reasonable and appropriate in light of the nature, quality and extent of services provided by the Investment Manager.

Profitability.    The Board reviewed detailed information regarding revenues received by the Investment Manager under the Management Agreement and related expenses. Based on the information provided, the Board concluded that the

24 The Korea Fund, Inc. Semi-Annual Report 12.31.17

The Korea Fund, Inc. Matters Relating to the Directors’ Consideration of the

Investment Management Agreement (unaudited) (continued)

estimated pre-tax profitability declared by the Investment Manager in connection with the management and administration of your Fund were not unreasonable.

Other Benefits to the Investment Manager and Its Affiliates.     The Board also considered the character and amount of other incidental benefits received by the Investment Manager for administrative services provided to your Fund. The Board also considered benefits to the Investment Manager related to brokerage allocations, including research generated by broker dealers, along with the incidental public relations benefits to the Investment Manager related to your Fund’s advertising opportunities. The Board concluded that management fees were reasonable in light of these indirect benefits.

Compliance.    The Board considered the significant attention and resources dedicated by the Investment Manager to documenting and enhancing their compliance processes. The Board noted in particular (i) the experience and seniority of the Investment Manager’s and the Fund’s chief compliance officers and (ii) the substantial commitment of resources by the Investment Manager to compliance matters.

Based on their evaluation of factors that they deemed to be material, including those factors described above, the Board, based on the renewal recommendation of its Contracts Committee, determined that the Management Agreement should be continued for an additional one-year period commencing January 1, 2018.
