SMALLCAP World Fund^®

Semi-annual report
for the six months ended
March 31, 2016

SMALLCAP World Fund seeks to provide you with long-term growth of capital.

This fund is one of more than 40 offered by one of the nation’s largest mutual fund families, American Funds, from Capital Group. For more than 80 years, Capital has invested with a long-term focus based on thorough research and attention to risk.

Fund results shown in this report, unless otherwise indicated, are for Class A shares at net asset value. If a sales charge (maximum 5.75%) had been deducted, the results would have been lower. Results are for past periods and are not predictive of results for future periods. Current and future results may be lower or higher than those shown. Share prices and returns will vary, so investors may lose money. Investing for short periods makes losses more likely. Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value. For current information and month-end results, visit americanfunds.com.

Here are the average annual total returns on a $1,000 investment with all distributions reinvested for periods ended March 31, 2016:

Class A shares	1 year	5 years	10 years
Reflecting 5.75% maximum sales charge	–10.88%	4.69%	4.87%

For other share class results, visit americanfunds.com and americanfundsretirement.com.

The total annual fund operating expense ratio was 1.07% for Class A shares as of the prospectus dated December 1, 2015.

Investment results assume all distributions are reinvested and reflect applicable fees and expenses. When applicable, investment results reflect fee waivers, without which results would have been lower. Visit americanfunds.com for more information.

Investing outside the United States may be subject to risks, such as currency fluctuations and political instability. These risks may be heightened in connection with investments in developing countries. Investing in small-capitalization stocks can involve greater risk than is customarily associated with investing in stocks of larger, more established companies. Refer to the fund prospectus and the Risk Factors section of this report for more information on these and other risks associated with investing in the fund.

 

Fellow investors:

Heightened volatility in global equity markets, with concerns about the Chinese economy a foremost factor, muted total returns for SMALLCAP World Fund in the first six months of its current fiscal year. For the six-month period ended March 31, 2016, the fund returned 0.22%. This figure includes the reinvestment of a one-time capital gain payment, made on December 23, 2015, of $2.83 a share.

By way of comparison, the MSCI All Country World Small Cap Index — an unmanaged index of global small-cap equities that does not include fees or expenses — gained 4.87% for the same period, while the Lipper Global Small-/Mid-Cap Funds Average, a measure of the fund’s peer group, returned 3.11%.

While we are not pleased with these short-term results, it’s worth remembering that we invest for the long term. We have always felt that volatility measured in weeks or months is a secondary concern to finding investments with long-term potential. As you can see in the table below, this approach has benefitted the fund’s shareholders,

The market index is unmanaged and, therefore, has no expenses. Investors cannot invest directly in an index. The market index is a free float-adjusted market capitalization weighted index that is designed to measure equity market results of smaller capitalization companies in both developed and emerging markets. Results reflect dividends net of withholding taxes. This index was not in existence when the fund’s Class A shares were first sold; therefore, lifetime results are not available.

Lipper averages reflect the current composition of all eligible mutual funds (all share classes) within a given category.

as the fund’s returns have surpassed those of its peers and benchmarks over longer periods. The fund’s Class R-5 shares were recently recognized by Lipper as offering the best 10-year returns in the Lipper Global Small-/Mid-Cap Funds category, our third straight year for this honor.

Market overview

The first half of the fund’s fiscal year was marked with deep uncertainty on a number of fronts. Foremost in many investors’ minds were concerns about weakness in the Chinese economy. A continued decline in oil prices also hurt many oil exporting economies in emerging markets.

These concerns were amplified by mixed economic data regarding the U.S. economy, as well as a particularly heated presidential campaign season. There were also concerns that the Federal Reserve would move ahead with a program of interest rate hikes through 2016.

All of this led to a sharp decline in global stocks in the first few months of the 2016 calendar year. However, this was quickly followed by gains in major equity markets. This sort of volatility is the mark of investor uncertainty, which may continue through the rest of the fund’s fiscal year.

The fund’s holdings

Overall, the fund had roughly 41% of its total portfolio in U.S.-based equities — less than the MSCI index, though returns from the fund’s U.S. equity holdings were largely negative during the period. Despite the uncertainty around China’s economy, the fund’s careful selection of Chinese stocks benefitted the fund on both an absolute and relative basis, as did holdings in Brazilian companies.

2 SMALLCAP World Fund

The fund’s health care holdings, which had long benefitted shareholders during this economic cycle, were detrimental to returns during this six-month period, and may signal a shift away from the leading role this industry had in the market. The fund’s holdings in information technology, materials and consumer stocks generally helped returns.

At the end of the six-month period, the fund held roughly 10% of the portfolio in cash and short-term securities. In volatile markets, cash not only can provide a buffer against volatility, but also can allow portfolio managers to take advantage of sudden price shifts by purchasing stocks at attractive valuations. Each individual portfolio manager determines how much cash he or she wishes to have on hand.

Looking ahead

There are reasons to be optimistic as we look to the remainder of the fund’s fiscal year. The Federal Reserve has signaled it will ease back on further rate hikes until the economy shows more signs of stability. In that vein, U.S. economic data has improved modestly. We expect the domestic economy to continue growing slowly — but grow nonetheless. Meanwhile the Chinese economy will remain challenged with the buildup of considerable debt.

While investor caution and uncertainty contributed to a lack of initial public offerings in the U.S. in the first quarter of 2016, we believe that merger and acquisition activity will become a more important factor for small-cap equities in the months ahead.

Despite all the uncertainties in the world, we will remain relentlessly focused on discovering potential investments for the fund. We have a steady flow of new investment ideas from our global research team, and the competition to discover SMALLCAP investment opportunities, and to uncover the latest insights into current holdings, remains intense and healthy.

In summary, we remain committed to our bottom-up research effort and our long-term orientation. We thank you for the continued trust you’ve placed in us, and look forward to reporting to you again in six months.

Cordially,

1. Organization

SMALLCAP World Fund, Inc. (the “fund”) is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The fund seeks to provide long-term growth of capital. Shareholders approved a proposal to reorganize the fund from a Maryland corporation to a Delaware statutory trust. The reorganization may be completed in the next year; however, the fund reserves the right to delay the implementation.

The fund has 18 share classes consisting of five retail share classes (Classes A, B and C, as well as two F share classes, F-1 and F-2), five 529 college savings plan share classes (Classes 529-A, 529-B, 529-C, 529-E and 529-F-1) and eight retirement plan share classes (Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6). The 529 college savings plan share classes can be used to save for college education. The retirement plan share classes are generally offered only through eligible employer-sponsored retirement plans. The fund’s share classes are described further in the following table:

Share class	Initial sales charge	Contingent deferred sales charge upon redemption	Conversion feature
Classes A and 529-A	Up to 5.75%	None (except 1% for certain redemptions within one year of purchase without an initial sales charge)	None
Classes B and 529-B*	None	Declines from 5% to 0% for redemptions within six years of purchase	Classes B and 529-B convert to Classes A and 529-A, respectively, after eight years
Class C	None	1% for redemptions within one year of purchase	Class C converts to Class F-1 after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	None
Class 529-E	None	None	None
Classes F-1, F-2 and 529-F-1	None	None	None
Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6	None	None	None

* Class B and 529-B shares of the fund are not available for purchase.

On November 20, 2015, the fund made an additional retirement plan share class (Class R-5E) available for sale pursuant to an amendment to its registration statement filed with the U.S. Securities and Exchange Commission. Refer to the fund’s prospectus for more details.

Holders of all share classes have equal pro rata rights to the assets, dividends and liquidation proceeds of the fund. Each share class has identical voting rights, except for the exclusive right to vote on matters affecting only its class. Share classes have different fees and expenses (“class-specific fees and expenses”), primarily due to different

SMALLCAP World Fund 17

arrangements for distribution, transfer agent and administrative services. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different per-share dividends by each share class.

2. Significant accounting policies

The fund is an investment company that applies the accounting and reporting guidance issued in Topic 946 by the U.S. Financial Accounting Standards Board. The fund’s financial statements have been prepared to comply with U.S. generally accepted accounting principles (“U.S. GAAP“). These principles require the fund’s investment adviser to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates. Subsequent events, if any, have been evaluated through the date of issuance in the preparation of the financial statements. The fund follows the significant accounting policies described in this section, as well as the valuation policies described in the next section on valuation.

Security transactions and related investment income — Security transactions are recorded by the fund as of the date the trades are executed with brokers. Realized gains and losses from security transactions are determined based on the specific identified cost of the securities. In the event a security is purchased with a delayed payment date, the fund will segregate liquid assets sufficient to meet its payment obligations. Dividend income is recognized on the ex-dividend date and interest income is recognized on an accrual basis. Market discounts, premiums and original issue discounts on fixed-income securities are amortized daily over the expected life of the security.

Class allocations — Income, fees and expenses (other than class-specific fees and expenses) and realized and unrealized gains and losses are allocated daily among the various share classes based on their relative net assets. Class-specific fees and expenses, such as distribution, transfer agent and administrative services, are charged directly to the respective share class.

Dividends and distributions to shareholders — Dividends and distributions to shareholders are recorded on the ex-dividend date.

Currency translation — Assets and liabilities, including investment securities, denominated in currencies other than U.S. dollars are translated into U.S. dollars at the exchange rates supplied by one or more pricing vendors on the valuation date. Purchases and sales of investment securities and income and expenses are translated into U.S. dollars at the exchange rates on the dates of such transactions. The effects of changes in exchange rates on investment securities are included with the net realized gain or loss and net unrealized appreciation or depreciation on investments in the fund’s statement of operations. The realized gain or loss and unrealized appreciation or depreciation resulting from all other transactions denominated in currencies other than U.S. dollars are disclosed separately.

3. Valuation

Capital Research and Management Company (“CRMC”), the fund’s investment adviser, values the fund’s investments at fair value as defined by U.S. GAAP. The net asset value of each share class of the fund is generally determined as of approximately 4:00 p.m. New York time each day the New York Stock Exchange is open.

Methods and inputs — The fund’s investment adviser uses the following methods and inputs to establish the fair value of the fund’s assets and liabilities. Use of particular methods and inputs may vary over time based on availability and relevance as market and economic conditions evolve.

Equity securities are generally valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades.

Fixed-income securities, including short-term securities, are generally valued at prices obtained from one or more pricing vendors. Vendors value such securities based on one or more of the inputs described in the following table. The table provides examples of inputs that are commonly relevant for valuing particular classes of fixed-income securities in which the fund is authorized to invest. However, these classifications are not exclusive, and any of the inputs may be used to value any other class of fixed-income security.

Fixed-income class	Examples of standard inputs
All	Benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, spreads and other relationships observed in the markets among comparable securities; and proprietary pricing models such as yield measures calculated using factors such as cash flows, financial or collateral performance and other reference data (collectively referred to as “standard inputs”)
Corporate bonds & notes; convertible securities	Standard inputs and underlying equity of the issuer
Bonds & notes of governments & government agencies	Standard inputs and interest rate volatilities

When the fund’s investment adviser deems it appropriate to do so (such as when vendor prices are unavailable or deemed to be not representative), fixed-income securities will be valued in good faith at the mean quoted bid and ask prices that are reasonably and timely available (or bid prices, if ask prices are not available) or at prices for securities of comparable maturity, quality and type.

Securities with both fixed-income and equity characteristics, or equity securities traded principally among fixed-income dealers, are generally valued in the manner described for either equity or fixed-income securities, depending on which method is deemed most

SMALLCAP World Fund 19

appropriate by the fund’s investment adviser. Forward currency contracts are valued at the mean of representative quoted bid and ask prices, generally based on prices supplied by one or more pricing vendors.

Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the fund’s investment adviser are fair valued as determined in good faith under fair valuation guidelines adopted by authority of the fund’s board of directors as further described. The investment adviser follows fair valuation guidelines, consistent with U.S. Securities and Exchange Commission rules and guidance, to consider relevant principles and factors when making fair value determinations. The investment adviser considers relevant indications of value that are reasonably and timely available to it in determining the fair value to be assigned to a particular security, such as the type and cost of the security; contractual or legal restrictions on resale of the security; relevant financial or business developments of the issuer; actively traded similar or related securities; conversion or exchange rights on the security; related corporate actions; significant events occurring after the close of trading in the security; and changes in overall market conditions. In addition, the closing prices of equity securities that trade in markets outside U.S. time zones may be adjusted to reflect significant events that occur after the close of local trading but before the net asset value of each share class of the fund is determined. Fair valuations and valuations of investments that are not actively trading involve judgment and may differ materially from valuations that would have been used had greater market activity occurred.

Processes and structure — The fund’s board of directors has delegated authority to the fund’s investment adviser to make fair value determinations, subject to board oversight. The investment adviser has established a Joint Fair Valuation Committee (the “Fair Valuation Committee”) to administer, implement and oversee the fair valuation process, and to make fair value decisions. The Fair Valuation Committee regularly reviews its own fair value decisions, as well as decisions made under its standing instructions to the investment adviser’s valuation teams. The Fair Valuation Committee reviews changes in fair value measurements from period to period and may, as deemed appropriate, update the fair valuation guidelines to better reflect the results of back testing and address new or evolving issues. The Fair Valuation Committee reports any changes to the fair valuation guidelines to the board of directors with supplemental information to support the changes. The fund’s board and audit committee also regularly review reports that describe fair value determinations and methods.

The fund’s investment adviser has also established a Fixed-Income Pricing Review Group to administer and oversee the fixed-income valuation process, including the use of fixed-income pricing vendors. This group regularly reviews pricing vendor information and market data. Pricing decisions, processes and controls over security valuation are also subject to additional internal reviews, including an annual control self-evaluation program facilitated by the investment adviser’s compliance group.

Classifications — The fund’s investment adviser classifies the fund’s assets and liabilities into three levels based on the inputs used to value the assets or liabilities. Level 1 values are based on quoted prices in active markets for identical securities. Level 2 values are based on significant observable market inputs, such as quoted prices for similar securities and quoted prices in inactive markets. Certain securities trading outside the U.S. may transfer between Level 1 and Level 2 due to valuation adjustments resulting from significant market movements following the close of local trading. Level 3 values are based on significant unobservable inputs that reflect the investment adviser’s determination of assumptions that market participants might reasonably use in valuing the securities. The valuation levels are not necessarily an indication of the risk or liquidity associated with the underlying investment. For example, U.S. government securities are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market. The following tables present the fund’s valuation levels as of March 31, 2016 (dollars in thousands):

4. Risk factors

Investing in the fund may involve certain risks including, but not limited to, those described below.

Market conditions — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries; overall market changes; local, regional or global political, social or economic instability; governmental or governmental agency responses to economic conditions; and currency exchange rate, interest rate and commodity price fluctuations.

Issuer risks — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives.

Investing in growth-oriented stocks — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

Investing in small companies — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies.

22 SMALLCAP World Fund

Investing outside the U.S. — Securities of issuers domiciled outside the U.S., or with significant operations or revenues outside the U.S., may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers operate or generate revenue. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as the imposition of price controls or punitive taxes, that could adversely impact revenues. Securities markets in certain countries may be more volatile and/or less liquid than those in the U.S. Investments outside the U.S. may also be subject to different accounting practices and different regulatory, legal and reporting standards and practices, and may be more difficult to value, than those in the U.S. In addition, the value of investments outside the U.S. may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund. The risks of investing outside the U.S. may be heightened in connection with investments in emerging markets.

Investing in emerging markets — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, developing countries may have less developed legal and accounting systems than those in developed countries. The governments of these countries may be less stable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or impose punitive taxes that could adversely affect the prices of securities. In addition, the economies of these countries may be dependent on relatively few industries that are more susceptible to local and global changes. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, and may be more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund’s net asset value. Additionally, there may be increased settlement risks for transactions in local securities.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the investment adviser in this process may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

5. Certain investment techniques

Forward currency contracts — The fund has entered into forward currency contracts, which represent agreements to exchange currencies on specific future dates at predetermined rates. The fund’s investment adviser uses forward currency contracts to

SMALLCAP World Fund 23

manage the fund’s exposure to changes in exchange rates. Upon entering into these contracts, risks may arise from the potential inability of counterparties to meet the terms of their contracts and from possible movements in exchange rates.

On a daily basis, the fund’s investment adviser values forward currency contracts and records unrealized appreciation or depreciation for open forward currency contracts in the fund’s statement of assets and liabilities. Realized gains or losses are recorded at the time the forward currency contract is closed or offset by another contract with the same broker for the same settlement date and currency.

Closed forward currency contracts that have not reached their settlement date are included in the respective receivables or payables for closed forward currency contracts in the fund’s statement of assets and liabilities. Net realized gains or losses from closed forward currency contracts and net unrealized appreciation or depreciation from open forward currency contracts are recorded in the fund’s statement of operations.

The following tables present the financial statement impacts resulting from the fund’s use of forward currency contracts as of, or for the six months ended, March 31, 2016 (dollars in thousands):

		Assets			Liabilities
		Location on statement of			Location on statement of
Contract	Risk type	assets and liabilities	Value		assets and liabilities	Value

Contract	Risk type	Location on statement of operations	Value		Location on statement of operations	Value
Forward currency	Currency	Net realized gain on forward currency contracts	$	17,108	Net unrealized depreciation on forward currency contracts	$	(19,025)

Collateral — The fund participates in a collateral program due to its use of forward currency contracts. The program calls for the fund to either receive or pledge collateral based on the net gain or loss on unsettled forward currency contracts by counterparty. The purpose of the collateral is to cover potential losses that could occur in the event that either party cannot meet its contractual obligations.

Rights of offset — The fund has entered into enforceable master netting agreements with certain counterparties for forward currency contracts, where on any date amounts payable by each party to the other (in the same currency with respect to the same

24 SMALLCAP World Fund

transaction) may be closed or offset by each party’s payment obligation. If an early termination date occurs under these agreements following an event of default or termination event, all obligations of each party to its counterparty are settled net through a single payment in a single currency (“close-out netting”). For financial reporting purposes, the fund does not offset financial assets and financial liabilities that are subject to these master netting arrangements in the statement of assets and liabilities.

The following table presents the fund’s forward currency contracts by counterparty that are subject to master netting agreements but that are not offset in the fund’s statement of assets and liabilities. The net amount column shows the impact of offsetting on the fund’s statement of assets and liabilities as of March 31, 2016 (dollars in thousands) if close-out netting was exercised:

6. Taxation and distributions

Federal income taxation — The fund complies with the requirements under Subchapter M of the Internal Revenue Code applicable to mutual funds and intends to distribute substantially all of its net taxable income and net capital gains each year. The fund is not subject to income taxes to the extent such distributions are made. Therefore, no federal income tax provision is required.

As of and during the period ended March 31, 2016, the fund did not have a liability for any unrecognized tax benefits. The fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the statement of operations. During the period, the fund did not incur any interest or penalties.

SMALLCAP World Fund 25

The fund is not subject to examination by U.S. federal tax authorities for tax years before 2011, by state tax authorities for tax years before 2010 and by tax authorities outside the U.S. for tax years before 2008.

Non-U.S. taxation — Dividend income is recorded net of non-U.S. taxes paid. The fund may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. As a result of rulings from European courts, the fund filed for additional reclaims related to prior years. These reclaims are recorded when the amount is known and there are no significant uncertainties on collectability. Gains realized by the fund on the sale of securities in certain countries are subject to non-U.S. taxes. The fund records a liability based on unrealized gains to provide for potential non-U.S. taxes payable upon the sale of these securities.

Distributions — Distributions paid to shareholders are based on net investment income and net realized gains determined on a tax basis, which may differ from net investment income and net realized gains for financial reporting purposes. These differences are due primarily to different treatment for items such as currency gains and losses; short-term capital gains and losses; capital losses related to sales of certain securities within 30 days of purchase; unrealized appreciation of certain investments in securities outside the U.S; deferred expenses; cost of investments sold; and income on certain investments . The fiscal year in which amounts are distributed may differ from the year in which the net investment income and net realized gains are recorded by the fund for financial reporting purposes.

The components of distributable earnings on a tax basis are reported as of the fund’s most recent year-end. As of September 30, 2015, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

Undistributed long-term capital gains $ 1,671,404

As of March 31, 2016, the tax basis unrealized appreciation (depreciation) and cost of investment securities were as follows (dollars in thousands):

Gross unrealized appreciation on investment securities	$	6,974,311
Gross unrealized depreciation on investment securities		(2,349,120	)
Net unrealized appreciation on investment securities		4,625,191
Cost of investment securities		22,107,837

7. Fees and transactions with related parties

CRMC, the fund’s investment adviser, is the parent company of American Funds Distributors,^® Inc. (“AFD”), the principal underwriter of the fund’s shares, and American Funds Service Company^® (“AFS”), the fund’s transfer agent. CRMC, AFD and AFS are considered related parties to the fund.

Investment advisory services — The fund has an investment advisory and service agreement with CRMC that provides for monthly fees accrued daily. These fees are based on a series of decreasing annual rates beginning with 0.800% on the first $1 billion of daily net assets and decreasing to 0.595% on such assets in excess of $27 billion. For the six months ended March 31, 2016, the investment advisory services fee was $82,529,000, which was equivalent to an annualized rate of 0.630% of average daily net assets.

SMALLCAP World Fund 27

Class-specific fees and expenses — Expenses that are specific to individual share classes are accrued directly to the respective share class. The principal class-specific fees and expenses are further described below:

Distribution services — The fund has plans of distribution for all share classes, except Class F-2, R-5E, R-5 and R-6 shares. Under the plans, the board of directors approves certain categories of expenses that are used to finance activities primarily intended to sell fund shares and service existing accounts. The plans provide for payments, based on an annualized percentage of average daily net assets, ranging from 0.30% to 1.00% as noted in this section. In some cases, the board of directors has limited the amounts that may be paid to less than the maximum allowed by the plans. All share classes with a plan may use up to 0.25% of average daily net assets to pay service fees, or to compensate AFD for paying service fees, to firms that have entered into agreements with AFD to provide certain shareholder services. The remaining amounts available to be paid under each plan are paid to dealers to compensate them for their sales activities.

For Class A and 529-A shares, distribution-related expenses include the reimbursement of dealer and wholesaler commissions paid by AFD for certain shares sold without a sales charge. These share classes reimburse AFD for amounts billed within the prior 15 months but only to the extent that the overall annual expense limit of 0.25% is not exceeded. As of March 31, 2016, there were no unreimbursed expenses subject to reimbursement for Class A or 529-A shares.

Share class	Currently approved limits			Plan limits
Class A		0.30	%		0.30	%
Class 529-A		0.30			0.50
Classes B and 529-B		1.00			1.00
Classes C, 529-C and R-1		1.00			1.00
Class R-2		0.75			1.00

Classes 529-E and R-3		0.50			0.75
Classes F-1, 529-F-1 and R-4		0.25			0.50

Transfer agent services — The fund has a shareholder services agreement with AFS under which the fund compensates AFS for providing transfer agent services to each of the fund’s share classes. These services include recordkeeping, shareholder communications and transaction processing. In addition, the fund reimburses AFS for amounts paid to third parties for performing transfer agent services on behalf of fund shareholders.

Administrative services — The fund has an administrative services agreement with CRMC under which the fund compensates CRMC for providing administrative services to Class A, C, F, 529 and R shares. These services include, but are not limited to, coordinating, monitoring, assisting and overseeing third parties that provide

28 SMALLCAP World Fund

services to fund shareholders. Under the agreement, Class A shares pay an annual fee of 0.01% and Class C, F, 529 and R shares pay an annual fee of 0.05% of their respective average daily net assets.

529 plan services — Each 529 share class is subject to service fees to compensate the Virginia College Savings Plan (“Virginia529”) for its oversight and administration of the 529 college savings plan. The quarterly fee is based on a series of decreasing annual rates beginning with 0.10% on the first $30 billion of the net assets invested in Class 529 shares of the American Funds and decreasing to 0.05% on such assets in excess of $70 billion. The fee for any given calendar quarter is accrued and calculated on the basis of the average net assets of Class 529 shares of the American Funds for the last month of the prior calendar quarter. The fee is included in other expenses in the fund’s statement of operations. Virginia529 is not considered a related party to the fund.

For the six months ended March 31, 2016, class-specific expenses under the agreements were as follows (dollars in thousands):

Directors’ deferred compensation — Directors who are unaffiliated with CRMC may elect to defer the cash payment of part or all of their compensation. These deferred amounts, which remain as liabilities of the fund, are treated as if invested in shares of the fund or other American Funds. These amounts represent general, unsecured liabilities of the fund and vary according to the total returns of the selected funds. Directors’ compensation of $(7,000) in the fund’s statement of operations reflects $217,000 in current fees (either paid in cash or deferred) and a net decrease of $224,000 in the value of the deferred amounts.

Affiliated officers and directors — Officers and certain directors of the fund are or may be considered to be affiliated with CRMC, AFD and AFS. No affiliated officers or directors received any compensation directly from the fund.

8. Committed line of credit

Effective April 29, 2016, the fund will participate with other funds managed by CRMC in a $500 million credit facility (the “line of credit”) to be utilized for temporary purposes to fund shareholder redemptions. The fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which will be reflected in other expenses in the fund’s statement of operations.

Expense example unaudited

As a fund shareholder, you incur two types of costs: (1) transaction costs, such as initial sales charges on purchase payments and contingent deferred sales charges on redemptions (loads), and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund so you can compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period (October 1, 2015, through March 31, 2016).

Actual expenses:

The first line of each share class in the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses paid during period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes:

The second line of each share class in the table on the following page provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio for the share class and an assumed rate of return of 5.00% per year before expenses, which is not the actual return of the share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5.00% hypothetical example with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Notes:

Retirement plan participants may be subject to certain fees charged by the plan sponsor, and Class F-1, F-2 and 529-F-1 shareholders may be subject to fees charged by financial intermediaries, typically ranging from 0.75% to 1.50% of assets annually depending on services offered. You can estimate the impact of these fees by adding the amount of the fees to the total estimated expenses you paid on your account during the period as calculated above. In addition, your ending account value would be lower by the amount of these fees.

Note that the expenses shown in the table on the following page are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line of each share class in the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

ITEM 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 8 – Portfolio Managers of Closed-End Management Investment Companies

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 9 – Purchases of Equity Securities by Closed-End Management Investment Company and Affiliated Purchasers

Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company.

ITEM 10 – Submission of Matters to a Vote of Security Holders

There have been no material changes to the procedures by which shareholders may recommend nominees to the Registrant’s board of directors since the Registrant last submitted a proxy statement to its shareholders. The procedures are as follows. The Registrant has a nominating and governance committee comprised solely of persons who are not considered ‘‘interested persons’’ of the Registrant within the meaning of the Investment Company Act of 1940, as amended. The committee periodically reviews such issues as the board’s composition, responsibilities, committees, compensation and other relevant issues, and recommends any appropriate changes to the full board of directors. While the committee normally is able to identify from its own resources an ample number of qualified candidates, it will consider shareholder suggestions of persons to be considered as nominees to fill future vacancies on the board. Such suggestions must be sent in writing to the nominating and governance committee of the Registrant, c/o the Registrant’s Secretary, and must be accompanied by complete biographical and occupational data on the prospective nominee, along with a written consent of the prospective nominee for consideration of his or her name by the nominating and governance committee.

ITEM 11 – Controls and Procedures

(a)	The Registrant’s Principal Executive Officer and Principal Financial Officer have concluded, based on their evaluation of the Registrant’s disclosure controls and procedures (as such term is defined in Rule 30a-3 under the Investment Company Act of 1940), that such controls and procedures are adequate and reasonably designed to achieve the purposes described in paragraph (c) of such rule.
(b)	There were no changes in the Registrant’s internal controls over financial reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940) that occurred during the Registrant’s second fiscal quarter of the period covered by this report that has materially affected, or is reasonably likely to materially affect, the Registrant’s internal control over financial reporting.

ITEM 12 – Exhibits

(a)(1)	Not applicable for filing of semi-annual reports to shareholders.
(a)(2)	The certifications required by Rule 30a-2 of the Investment Company Act of 1940 and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 are attached as exhibits hereto.
