Beginning January 1, 2021, as permitted by regulations adopted by the U.S. Securities and Exchange Commission, we intend to no longer mail paper copies of the fund’s shareholder reports, unless specifically requested from American Funds or your financial intermediary, such as a broker-dealer or bank. Instead, the reports will be made available on the American Funds website (americanfunds.com); you will be notified by mail and provided with a website link to access the report each time a report is posted. If you have already elected to receive shareholder reports electronically, you will not be affected by this change and do not need to take any action. If you prefer to receive shareholder reports and other communications electronically, you may update your mailing preferences with your financial intermediary, or enroll in e-delivery at americanfunds.com (for accounts held directly with the fund).

You may elect to receive paper copies of all future reports free of charge. If you invest through a financial intermediary, you may contact your financial intermediary to request that you continue to receive paper copies of your shareholder reports. If you invest directly with the fund, you may inform American Funds that you wish to continue receiving paper copies of your shareholder reports by contacting us at (800) 421-4225. Your election to receive paper reports will apply to all funds held with American Funds or through your financial intermediary.

Capital Income Builder seeks to provide you with a level of current income that exceeds the average yield on U.S. stocks generally and to provide you with a growing stream of income over the years. The fund’s secondary objective is to provide you with growth of capital.

This fund is one of more than 40 offered by Capital Group, home of American Funds, one of the nation’s largest mutual fund families. For more than 85 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. 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, 2019 (the most recent calendar quarter-end): 

Class A shares	1 year	5 years	10 years
Reflecting 5.75% maximum sales charge	-2.40%	3.28%	8.54%

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

The total annual fund operating expense ratio was 0.58% for Class A shares as of the prospectus dated January 1, 2019 (as supplemented to date).

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.

The fund’s 30-day yield for Class A shares as of May 31, 2019, reflecting the 5.75% maximum sales charge and calculated in accordance with the U.S. Securities and Exchange Commission formula, was 3.04%.

The return of principal for bond funds and for funds with significant underlying bond holdings is not guaranteed. Fund shares are subject to the same interest rate, inflation and credit risks associated with the underlying bond holdings. Investing outside the United States may be subject to additional risks, such as currency fluctuations, periods of illiquidity and price volatility. These risks may be heightened in connection with investments in developing countries. 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.

Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value.

Fellow investors:

Global equity markets rose over the first half of Capital Income Builder’s fiscal year despite volatility fueled by shifting investor sentiment on interest rates and trade. More defensive, higher dividend-paying stocks generally lagged. For the six months ended April 30, 2019, the fund achieved a total return of 7.70%, with all dividends reinvested. By way of comparison, the MSCI ACWI (All Country World Index), a measure of returns for stock markets in 47 countries, rose 9.37%. Meanwhile, Bloomberg Barclays U.S. Aggregate Index, a broad measure of U.S. fixed income markets, gained 5.49%. The fund’s peer group, as measured by the Lipper Global Equity Income Funds Average, gained 7.18% for the period.

Dividend income

The fund paid regular dividends of 50 cents a share in December 2018 and March 2019. In addition, a special dividend of 14 cents a share was paid in December.

Capital Income Builder 1

The fund strives to grow its dividend and provide a special dividend each fiscal year, though its ability to do so is dependent on market conditions. Capital Income Builder recorded a 12-month yield of 3.49% as of April 30, 2019, greater than that of the Lipper Global Equity Income Funds Average (2.92%), MSCI ACWI (2.47%) and Bloomberg Barclays U.S. Aggregate Index (2.97%).

The current environment

Dividend-paying stocks generated mixed results over the period. Higher yielding sectors led their cyclical counterparts when global stocks fell sharply in December amid concerns about slowing global economic growth, tightening monetary policy and deteriorating trade tensions between the U.S. and China. However, global markets rebounded in the new year amid signs of progress in trade negotiations and clear signals that the U.S. Federal Reserve would hold off on further rate hikes. Higher yielding sectors generally lagged in the subsequent rally.

Looking at the global market, information technology led all sectors, advancing 14.63%. Facebook and Google parent Alphabet rose despite heightened scrutiny of their business practices, while Microsoft benefited from better-than-expected earnings. The more rate-sensitive real estate sector gained 14.39% as the Fed ditched plans for further hikes. Communication services stocks also rose. In contrast, energy was the worst-returning sector (rising 0.82%) as oil prices were volatile. Health care rose by a tepid 2.17% amid investor concerns about proposals to expand government-administered coverage in the U.S. Financials stocks, which would have benefited from higher interest rates, also lagged the broader market.

European stocks trailed the broader U.S. market. Emerging markets stocks led their developed-world counterparts, as China stocks rallied sharply. The U.S. fixed income market advanced as yields fell following the Fed’s rate decision. In currencies, the euro fell against the U.S. dollar, while the Japanese yen and British pound rose.

A look at the portfolio

As of April 30, consumer staples was the biggest sector among the fund’s equity holdings, comprising 9.8% of total net assets. Financials followed at 8.9%. Investments in U.S. equities represented 36.2% of the fund’s overall holdings, while non-U.S. equities made up 33.3%.

Results were mixed for the fund’s 10 largest holdings over the period. Broadcom shares advanced after the company reaffirmed its full-year forecasts. Microsoft rose on strong results at its cloud-computing unit. Crown Castle International, a real estate investment trust, was helped by the Fed’s

more dovish stance. Coca-Cola also rose. On the other hand, Royal Dutch Shell declined amid volatile oil prices. Tobacco stocks Altria, Philip Morris International and British American Tobacco fell, pressured by competition from vaping devices and a possible crackdown on menthol in cigarettes. Shares of drugmaker Novartis fell in price terms.

Overall, the fund’s fixed income rose in value. Holdings consist primarily of government, corporate and mortgage-backed securities.

The road ahead

The market decline toward the end of 2018 served as a reminder of the defensive properties of dividend-paying stocks, which tend to outpace more cyclical equities in market declines. This potential resilience could be valuable in the coming year, as a number of risks could spark further volatility. Although the U.S. economy appears to be healthy, growth in other countries remains generally sluggish. Furthermore, there are geopolitical risks from unpredictable, fast-moving U.S.-China trade negotiations. And a more dovish Fed policy may result in greater-than-expected inflation.

In addition to seeking current income, the fund also invests in companies that can grow dividends over time. The emphasis on dividend growth gives the fund flexibility to invest in companies outside traditionally higher yielding industries and sectors — such as information technology and biotechnology. When pursuing dividend growth, portfolio managers look for companies they believe have the willingness and financial capacity to increase the dividend. Moreover, the fund is a global strategy that can seek attractive dividend-paying stocks abroad. Valuations abroad for dividend-paying companies in many cases are more compelling than in the U.S.

We appreciate your investment in the fund, and look forward to communicating with you in six months.

Cordially,

James B. Lovelace Co-President	David A. Hoag Co-President	Steven T. Watson Co-President

1. Organization

Capital Income Builder (the “fund”) is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The fund seeks to provide a level of current income that exceeds the average yield on U.S. stocks generally and a growing stream of income over the years. Growth of capital is a secondary objective.

The fund has 19 share classes consisting of six retail share classes (Classes A, C, T, F-1, F-2 and F-3), five 529 college savings plan share classes (Classes 529-A, 529-C, 529-E, 529-T 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 18 months of purchase without an initial sales charge)	None
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	Class 529-C converts to Class 529-A after 10 years
Class 529-E	None	None	None
Classes T and 529-T*	Up to 2.50%	None	None
Classes F-1, F-2, F-3 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 T and 529-T shares are not available for purchase.

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 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.

Capital Income Builder 17

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.

Distributions paid to shareholders — Income dividends and capital gain distributions 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
Mortgage-backed; asset-backed obligations	Standard inputs and cash flows, prepayment information, default rates, delinquency and loss assumptions, collateral characteristics, credit enhancements and specific deal information
Municipal securities	Standard inputs and, for certain distressed securities, cash flows or liquidation values using a net present value calculation based on inputs that include, but are not limited to, financial statements and debt contracts

Capital Income Builder 19

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 appropriate by the fund’s investment adviser. The Capital Group Central Cash Fund (“CCF”) is valued based upon a floating net asset value, which fluctuates with changes in the value of CCF’s portfolio securities. The underlying securities are valued based on the policies and procedures in CCF’s statement of additional information. Exchange-traded futures are generally valued at the official settlement price of the exchange or market on which such instruments are traded, as of the close of business on the day the futures are being valued. 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. Interest rate swaps are generally valued by pricing vendors based on market inputs that include the index and term of index, reset frequency, payer/receiver, currency and pay frequency.

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 trustees 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.

20 Capital Income Builder

Processes and structure — The fund’s board of trustees 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 trustees. 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 tables on the following page present the fund’s valuation levels as of April 30, 2019 (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 common stocks, bonds and other 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, governmental agency or central bank responses to economic conditions; and currency exchange rate, interest rate and commodity price fluctuations. These risks may be heightened in the case of smaller capitalization stocks.

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, major litigation against the issuer, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives.

Investing in income-oriented stocks — The value of the fund’s securities and income provided by the fund may be reduced by changes in the dividend policies of, and the capital resources available for dividend payments at, the companies in which the fund invests.

Investing in debt instruments — The prices of, and the income generated by, bonds and other debt securities held by the fund may be affected by changing interest rates and by changes in the effective maturities and credit ratings of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. A general rise in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund failing to recoup the full amount of its initial investment and having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. A downgrade or default affecting any of the fund’s securities could cause the value of the fund’s shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price

Capital Income Builder 23

fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which the fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund’s investment adviser relies on its own credit analysts to research issuers and issues in seeking to assess credit and default risks.

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 nationalization, currency blockage or the imposition of price controls or punitive taxes each of which could adversely impact the value of these securities. 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.

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, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and 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

Index-linked bonds — The fund has invested in index-linked bonds, which are fixed-income securities whose principal value is periodically adjusted to a government price index. Over the life of an index-linked bond, interest is paid on the adjusted principal value. Increases or decreases in the principal value of index-linked bonds are recorded as interest income in the fund’s statement of operations.

Mortgage dollar rolls — The fund has entered into mortgage dollar roll transactions in which the fund sells a mortgage-backed security to a counterparty and simultaneously enters into an agreement with the same counterparty to buy back a similar security on a specific future date at a predetermined price. Mortgage dollar rolls are accounted for as purchase and sale transactions. Portfolio turnover rates excluding and including mortgage dollar rolls are presented at the end of the fund’s financial highlights table.

24 Capital Income Builder

Loan transactions — The fund has entered into loan transactions in which the fund acquires a loan either through an agent, by assignment from another holder, or as a participation interest in another holder’s portion of a loan. The loan is often administered by a financial institution that acts as agent for the holders of the loan, and the fund may be required to receive approval from the agent and/or borrower prior to the sale of the investment. The loan’s interest rate and maturity date may change based on the terms of the loan, including potential early payments of principal.

Futures contracts — The fund has entered into futures contracts, which provide for the future sale by one party and purchase by another party of a specified amount of a specific financial instrument for a specified price, date, time and place designated at the time the contract is made. Futures contracts are used to strategically manage the fund’s interest rate sensitivity by increasing or decreasing the duration of the fund or a portion of the fund’s portfolio.

Upon entering into futures contracts, and to maintain the fund’s open positions in futures contracts, the fund is required to deposit with a futures broker, known as a futures commission merchant (“FCM”), in a segregated account in the name of the FCM an amount of cash, U.S. government securities or other liquid securities, known as initial margin. The margin required for a particular futures contract is set by the exchange on which the contract is traded to serve as collateral, and may be significantly modified from time to time by the exchange during the term of the contract. Securities deposited as initial margin, if any, are disclosed in the investment portfolio and cash deposited as initial margin, if any, is reflected as restricted cash pledged for futures contracts in the fund’s statement of assets and liabilities.

On a daily basis, the fund pays or receives variation margin based on the increase or decrease in the value of the futures contracts and records variation margin on futures contracts in the statement of assets and liabilities. In addition, the fund segregates liquid assets equivalent to the fund’s outstanding obligations under the contract in excess of the initial margin and variation margin, if any. Futures contracts may involve a risk of loss in excess of the variation margin shown on the fund’s statement of assets and liabilities. The fund records realized gains or losses at the time the futures contract is closed or expires. Net realized gains or losses and net unrealized appreciation or depreciation from futures contracts are recorded in the fund’s statement of operations. The average month-end notional amount of futures contracts while held was $4,756,063,000.

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 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.

Capital Income Builder 25

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 average month-end notional amount of open forward currency contracts while held was $444,047,000.

Interest rate swaps — The fund has entered into interest rate swap contracts, which are agreements to exchange one stream of future interest payments for another based on a specified notional amount. Typically, interest rate swaps exchange a fixed interest rate for a payment that floats relative to a benchmark or vice versa. The fund’s investment adviser uses interest rate swaps to seek to manage the interest rate sensitivity of the fund by increasing or decreasing the duration of the fund or a portion of the fund’s portfolio. Risks may arise as a result of the fund’s investment adviser incorrectly anticipating changes in interest rates, increased volatility, reduced liquidity and the potential inability of counterparties to meet the terms of their agreements.

Upon entering into an interest rate swap contract, the fund is required to deposit cash, U.S. government securities or other liquid securities, which is known as initial margin. Generally, the initial margin required for a particular interest rate swap is set and held as collateral by the clearinghouse on which the contract is cleared. The amount of initial margin required may be significantly modified from time to time by the clearinghouse during the term of the contract.

On a daily basis, the fund’s investment adviser records daily interest accruals related to the exchange of future payments as a receivable and payable in the fund’s statement of assets and liabilities. The fund also pays or receives a variation margin based on the increase or decrease in the value of the interest rate swaps, including accrued interest, and records variation margin on interest rate swaps in the statement of assets and liabilities. The fund records realized gains and losses on both the net accrued interest and any gain or loss recognized at the time the interest rate swap is closed or expires. Net realized gains or losses, as well as any net unrealized appreciation or depreciation, from interest rate swaps are recorded in the fund’s statement of operations. The average month-end notional amount of interest rate swaps while held was $607,667,000.

* Includes cumulative appreciation/depreciation on futures contracts and interest rate swaps as reported in the applicable tables following the fund’s investment portfolio. Only current day’s variation margin is reported within the statement of assets and liabilities.

Collateral — The fund participates in a collateral program that calls for the fund to either receive or pledge highly liquid assets, such as cash or U.S. government securities, as collateral due to its use of futures contracts, forward currency contracts, interest rate swaps and future delivery contracts. For futures contracts and interest rate swaps, the program calls for the fund to pledge collateral for initial and variation margin by contract. For 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. For future delivery contracts, the program calls for the fund to either receive or pledge collateral based on the net gain or loss on unsettled contracts by certain counterparties. The purpose of the collateral is to cover potential losses that could occur in the event that either party cannot meet its contractual obligation. Non-cash collateral pledged by the fund, if any, is disclosed in the fund’s investment portfolio, and cash

Capital Income Builder 27

collateral pledged by the fund, if any, is held in a segregated account with the fund’s custodian, which is reflected as pledged cash in the fund’s statement of assets and liabilities.

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 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 April 30, 2019, if close-out netting was exercised (dollars in thousands):

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 April 30, 2019, 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 significant interest or penalties.

28 Capital Income Builder

The fund’s tax returns are not subject to examination by federal, state and, if applicable, non-U.S. tax authorities after the expiration of each jurisdiction’s statute of limitations, which is generally three years after the date of filing but can be extended in certain jurisdictions.

Non-U.S. taxation — Dividend and interest income are 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, if any, may be subject to non-U.S. taxes. If applicable, the fund records an estimated deferred tax 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.; cost of investments sold; net capital losses; amortization of premiums and discounts 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 October 31, 2018, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

Undistributed ordinary income	$	572,023
Capital loss carryforward*		(418,067	)

* The capital loss carryforward will be used to offset any capital gains realized by the fund in the current year or in subsequent years. The fund will not make distributions from capital gains while a capital loss carryforward remains.

As of April 30, 2019, the tax basis unrealized appreciation (depreciation) and cost of investments were as follows (dollars in thousands):

Gross unrealized appreciation on investments	$	15,387,371
Gross unrealized depreciation on investments		(4,063,211	)
Net unrealized appreciation on investments		11,324,160
Cost of investments		92,739,373

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 0.240% on the first $1 billion of daily net assets and decreasing to 0.110% on such assets in excess of $115 billion. The agreement also provides for monthly fees, accrued daily, based on a series of decreasing rates beginning with 3.00% on the first $100,000,000 of the fund’s monthly gross income and decreasing to 2.50% on such income in excess of $100,000,000. For the six months ended April 30, 2019, the investment advisory services fee was $115,963,000, which was equivalent to an annualized rate of 0.233% of average daily net assets.

30 Capital Income Builder

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, F-3, R-5E, R-5 and R-6 shares. Under the plans, the board of trustees 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 trustees 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.

Share class	Currently approved limits			Plan limits
Class A		0.30	%		0.30	%
Class 529-A		0.30			0.50
Classes C, 529-C and R-1		1.00			1.00
Class R-2		0.75			1.00
Class R-2E		0.60			0.85
Classes 529-E and R-3		0.50			0.75
Classes T, F-1, 529-T, 529-F-1 and R-4		0.25			0.50

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 limits are not exceeded. As of April 30, 2019, there were no unreimbursed expenses subject to reimbursement for Class A or 529-A shares.

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.

Capital Income Builder 31

Administrative services — The fund has an administrative services agreement with CRMC under which the fund compensates CRMC for providing administrative services to all share classes. Administrative services are provided by CRMC and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders. The agreement provides the fund the ability to charge an administrative services fee at the annual rate of 0.05% of the daily net assets attributable to each share class of the fund. Currently Class A shares pay an administrative services fee at the annual rate of 0.01% of daily net assets and all other share classes pay a fee at the annual rate of 0.05% of their respective daily net assets. The fund’s board of trustees authorized effective July 1, 2019, an administrative services fee at the annual rate of 0.03% of the daily net assets attributable to each share class of the fund (which could increase as noted above) for its provision of administrative services.

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 CollegeAmerica 529 college savings plan. The fee is based on the combined net assets invested in Class 529 and ABLE shares of the American Funds. Class ABLE shares are offered on other American Funds by Virginia529 through ABLEAmerica, a tax-advantaged savings program for individuals with disabilities. The quarterly fee is based on a series of decreasing annual rates beginning with 0.10% on the first $20 billion of the combined net assets invested in the American Funds and decreasing to 0.03% on such assets in excess of $100 billion. The fee for any given calendar quarter is accrued and calculated on the basis of the average net assets of Class 529 and ABLE 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.

Trustees’ deferred compensation — Trustees 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. Trustees’ compensation of $182,000 in the fund’s statement of operations reflects $176,000 in current fees (either paid in cash or deferred) and a net increase of $6,000 in the value of the deferred amounts.

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

Investment in CCF — The fund holds shares of CCF, an institutional prime money market fund managed by CRMC. CCF invests in high-quality, short-term money market instruments. CCF is used as the primary investment vehicle for the fund’s short-term investments. CCF shares are only available for purchase by CRMC, its affiliates, and other funds managed by CRMC and are not available to the public. CRMC does not receive an investment advisory services fee from CCF.

Capital Income Builder 33

Security transactions with related funds — The fund has purchased from, and sold securities to, other funds managed by CRMC (or funds managed by certain affiliates of CRMC) under procedures adopted by the fund’s board of trustees. The funds involved in such transactions are considered related by virtue of having a common investment adviser (or affiliated investment advisers), common trustees and/or common officers.

1	Based on average shares outstanding.
2	For the year ended October 31, 2014, this column reflects the impact of a corporate action event that resulted in a one-time increase to net investment income. If the corporate action event had not occurred, the Class A net investment income per share would have been lower by $.68; the Class A ratio of expenses to average net assets would have been lower by .03 percentage points; and the Class A ratio of net income to average net assets would have been lower by 1.15 percentage points. The impact to the other share classes would have been similar.
3	Total returns exclude any applicable sales charges, including contingent deferred sales charges.
4	Based on operations for a period that is less than a full year.
5	Unaudited.
6	Not annualized.
7	Annualized.
8	All or a significant portion of assets in this class consisted of seed capital invested by CRMC and/or its affiliates. Fees for distribution services are not charged or accrued on these seed capital assets. If such fees were paid by the fund on seed capital assets, fund expenses would have been higher and net income and total return would have been lower.

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 (November 1, 2018, through April 30, 2019).

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 titled “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, F-3 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.

The Capital Advantage^®

Since 1931, Capital Group, home of American Funds, has helped investors pursue long-term investment success. Our consistent approach — in combination with The Capital System^SM — has resulted in superior outcomes.

Aligned with investor success

We base our decisions on a long-term perspective, which we believe aligns our goals with the interests of our clients. Our portfolio managers average 27 years of investment experience, including 20 years at our company, reflecting a career commitment to our long-term approach.¹

The Capital System

The Capital System combines individual accountability with teamwork. Funds using The Capital System are divided into portions that are managed independently by investment professionals with diverse backgrounds, ages and investment approaches. An extensive global research effort is the backbone of our system.

American Funds’ superior outcomes

Equity funds have beaten their Lipper peer indexes in 92% of 10-year periods and 99% of 20-year periods.² Fixed income funds have helped investors achieve diversification through attention to correlation between bonds and equities.³ Fund management fees have been among the lowest in the industry.⁴

1	Portfolio manager experience as of December 31, 2018.
2	Based on Class F-2 share results for rolling periods through December 31, 2018. Periods covered are the shorter of the fund’s lifetime or since the comparable Lipper index inception date (except Capital Income Builder and SMALLCAP World Fund, for which the Lipper average was used). Expenses differ for each share class, so results will vary.
3	Based on Class F-2 share results, as of December 31, 2018. Fourteen of our 15 American Funds fixed income funds that have been in existence for the three-year period showed a three-year correlation below 0.2. Standard & Poor’s 500 Composite Index was used as an equity market proxy. Correlation based on monthly total returns. Correlation is a statistical measure of how two securities move in relation to each other. A correlation ranges from –1 to 1. A positive correlation close to 1 implies that as one security moves, either up or down, the other security will move in “lockstep,” in the same direction. A negative correlation close to –1 indicates that the securities have moved in the opposite direction.
4	On average, our management fees were in the lowest quintile 70% of the time, based on the 20-year period ended December 31, 2018, versus comparable Lipper categories, excluding funds of funds.

Class F-2 shares were first offered on August 1, 2008. Class F-2 share results prior to the date of first sale are hypothetical based on Class A share results without a sales charge, adjusted for typical estimated expenses. Results for certain funds with an inception date after August 1, 2008, also include hypothetical returns because those funds’ Class F-2 shares sold after the funds’ date of first offering. Please see americanfunds.com for more information on specific expense adjustments and the actual dates of first sale.

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 trustees 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 trustees. 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.

(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 semi-annual period covered by this report that has materially affected, or is reasonably likely to materially affect, the Registrant’s internal control over financial reporting.
