real-life objectives.

American Funds Portfolio Series seeks to help investors meet a wide range of investment goals, including preservation of capital, income, balance and growth. Each fund in the series is an objective-based portfolio of actively managed American Funds.

American Funds, from Capital Group, is 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 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 total returns on a $1,000 investment with all distributions reinvested for periods ended September 30, 2017 (the most recent calendar quarter-end). Also shown are the gross expense ratios as of the series prospectus dated January 1, 2018 (unaudited):

Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The portfolio series funds invest in Class R-6 shares of the underlying funds. The investment adviser is currently reimbursing a portion of other expenses for American Funds Tax-Exempt Preservation Portfolio, and has in the past reimbursed certain expenses for other funds. Fund results and the net expense ratio reflect the reimbursements, without which the results would have been lower and the expenses would have been higher. After January 1, 2019, the adviser may modify or terminate the reimbursements. Expense ratios are as of each fund’s prospectus available at the time of publication and include the weighted average expenses of the underlying funds.

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

Investment allocations may not achieve fund objectives. There are expenses associated with the underlying funds in addition to fund of funds expenses. The funds’ risks are directly related to the risks of the underlying funds. Refer to the series prospectus and the Risk Factors section of this report for more information on these and other risks associated with investing in the series.

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:

It is our pleasure to present the annual report for the American Funds Portfolio Series, for the 12-month period ended October 31, 2017.

Amid advancing stock and bond markets, all of the portfolios returned positive results over the fiscal year. Growth-focused equity funds of funds led, with returns for the period at 26.05% (American Funds Global Growth Portfolio) and 24.39% (American Funds Growth Portfolio). More conservative, fixed income portfolios trailed with returns of 0.81% to 0.08% (American Funds Tax-Exempt Preservation Portfolio and American Funds Preservation Portfolio, respectively).

As always, we encourage investors to keep short-term results in their proper perspective.

About the series

The American Funds Portfolio Series consists of eight funds of funds that are designed to help investors pursue real-life goals, both long- and short-term, within a framework of three common objectives: preservation, balance and growth. These funds of funds can be used individually or in combination, based on an investor’s needs, risk tolerance and time horizon (the total length of time that an investor expects to hold a security or portfolio, before it will be used to fund retirement or college, for example).

The series was created by the American Funds Portfolio Oversight Committee, a group of seasoned investment professionals with varied backgrounds, diverse investment approaches and decades of experience. In creating the series, the Committee carefully selects a mix of individual American Funds, employing an objective-based process and rigorous analysis. The Committee regularly monitors each fund in the series.

The economy

The global economy remained on solid footing during the series’ fiscal year. In fact, the vast majority of countries experienced economic growth. This unusual occurrence was not attributable to policy developments in any one country, but rather a number of disparate factors.

The U.S. economy has strengthened consistently since 2009, with only a handful of modest declines in the overall pattern. The rate of growth has been moderate, but with the economy near full employment and inflation low, the picture remains positive despite political uncertainties.

While European markets lagged during much of the post-2009 period, they have improved considerably in the past fiscal year, with some nations outpacing the U.S. Meanwhile, concerns about China have abated since the government instituted policy measures designed to stimulate the country’s economy.

Thus, with the U.S., Europe and China all on a growth trajectory, the rest of the world has largely followed.

The stock market

Since last November the U.S. has enjoyed a strong bull market, which has shown little sign of tempering as of this writing. This is consistent with sound corporate balance sheets and earnings, as well as the state of the economy and the low level of market volatility.

That said, U.S. equities exhibit higher valuations than may be warranted by fundamentals. We believe this is due in large part to anticipation of further government policy changes, particularly with regard to corporate taxes and deregulation.

Overseas, equities have generally fared well despite a number of geopolitical uncertainties. The implications of Brexit for the United Kingdom and European Union, continued instability in the Middle East, and tensions between the U.S. and North Korea have not had a major impact on most markets.

The bond market

Since January, the fixed income market has seen a surge in prices, making bonds more expensive and keeping yields

American Funds Portfolio Series 1

relatively low. The sell-off that took place in the wake of the U.S. presidential election has gradually reversed since the start of the calendar year. On a day-to-day basis, the inverse correlation between equities and bonds remains intact — if stocks rise, bond prices generally fall. However, the overall trend in 2017 has been an increase in bond prices.

There are a number of potential factors at play. In the past, we’ve often seen a decline in equities when there has been uncertainty in the political or economic environment, but in this instance it may have initiated the rise in bond prices. There’s also been a greater appetite for fixed income securities in general, which may be due to more people entering retirement and seeking diversification from equities.

Inside the series

As the eight portfolios in the series are combinations of individual funds, the results of the underlying funds are a primary driver of the series results. Broadly speaking, investments in equity funds outpaced those in fixed income funds and all portfolios within the series delivered positive results. Growth-oriented funds of funds tended to have larger holdings in information technology companies, and this helped them outpace funds of funds with an income focus. Within fixed income, funds with meaningful investments in lower quality, higher yielding bonds outpaced those with larger positions in higher quality, lower yielding securities.

The table on page 3 shows the lifetime results for the funds (since May 18, 2012). Please keep in mind that this five-and-a-half-year period is still a relatively brief investment time frame. As always, we encourage investors to have a long-term outlook, particularly since the funds in the series are designed as long-term investments.

Note that effective January 1, 2018, in order to help clarify the objective of each portfolio, the names of three of the funds of funds within the American Funds Portfolio Series will change:

• American Funds Balanced Portfolio^SM will become American Funds Moderate Growth and Income Portfolio^SM

• American Funds Income Portfolio^SM will become American Funds Conservative Growth and Income Portfolio^SM

• American Funds Tax-Advantaged Income Portfolio^SM will become American Funds Tax-Advantaged Growth and Income Portfolio^SM

Moving forward

Looking ahead, we see no real roadblocks to continued growth around the world. While there has been — and will be —volatility in various parts of the market, the types of economic imbalances that preceded past recessions are not apparent today.

With the economic picture generally sound, any potential setbacks to securities prices would have to come from an external shock that would disrupt markets or undermine investor confidence. For example, failure to enact tax reform in the U.S. could prompt a decline in equities, as current prices reflect optimism on that count. A military escalation with North Korea may unsettle markets, particularly in Asia.

While the incidence and timing of these kinds of shocks cannot be predicted, it is still useful to undertake a close analysis of these scenarios and the factors that influence their probabilities. The investment professionals working on behalf of the series’ underlying funds continuously monitor global economies and markets for any sign of change.

Fund allocations in the series are not determined by short- or medium-term market forecasts, nor are allocations changed in response to competitive pressures. Any shifts made to investments by analysts and portfolio managers are based on bottom-up fundamentals — an approach that we’ve found works well in lieu of any sort of tactical, top-down process. Our focus remains on the long term, and we encourage you to adopt a similar perspective with regard to your investments.

As always, we thank you for entrusting your assets to our care. We look forward to reporting to you again in six months.

Cordially,

Bradley J. Vogt
Vice Chairman of the Board

Walter R. Burkley
President

Why your annual report has a different look

You have probably noticed that this annual report doesn’t look like the glossier reports of the past. After surveying a large, representative sample of our investors, we have decided to make a few key changes to these documents and have adjusted the look and feel of our reports (e.g., paper stock and design standards) to reflect the prevailing industry norm. These changes will reduce costs and the amount of paper we consume.

You also told us that we should be considering ways to deliver the valuable perspective of our investment professionals to you digitally. We are in the process of building our digital investor education content on our website, which will provide a platform for investment professionals to communicate with investors using the channels that you access more often.

If you have not already done so, you can elect to receive your annual reports electronically. Once you do, you will receive an email notification as soon as the documents are available. To learn more, visit americanfunds.com/gopaperless. n

American Funds Portfolio Series 27

Notes to financial statements

1. Organization

American Funds Portfolio Series (the “series”) is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The series consists of eight funds (the “funds”). The assets of each fund are segregated, with each fund accounted for separately. The funds’ investment objectives are as follows:

American Funds Global Growth Portfolio	Seeks long-term growth of capital.
American Funds Growth Portfolio	Seeks long-term growth of capital.
American Funds Growth and Income Portfolio	Seeks long-term growth of capital while providing current income.
American Funds Balanced Portfolio	Seeks current income and long-term growth of capital and income.
American Funds Income Portfolio	Seeks current income and, secondarily, long-term growth of capital.
American Funds Tax-Advantaged Income Portfolio	Seeks current income, a portion of which is exempt from regular federal income tax, while secondarily striving for long-term growth of capital.
American Funds Preservation Portfolio	Seeks current income, consistent with preservation of capital.
American Funds Tax-Exempt Preservation Portfolio	Seeks current income that is exempt from regular federal income tax, consistent with preservation of capital.

Each fund will attempt to achieve its investment objectives by investing in a mix of American Funds (the “underlying funds”) in different combinations and weightings. Capital Research and Management Company (“CRMC”), the series’ investment adviser, is also the investment adviser to the underlying funds.

The Global Growth Portfolio, Growth Portfolio, Growth and Income Portfolio, Balanced Portfolio, Income Portfolio and Preservation Portfolio each have 21 share classes consisting of seven retail share classes (Classes A, B, C, T, F-1, F-2 and F-3), six 529 college savings plan share classes (Classes 529-A, 529-B, 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 Tax-Advantaged Income Portfolio and Tax-Exempt Preservation Portfolio each have seven retail share classes (Classes A, B, C, T, F-1, F-2 and F-3). The funds’ 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 2.50% for Preservation Portfolio and Tax-Exempt Preservation Portfolio; up to 3.75% for Tax-Advantaged Income Portfolio; up to 5.75% for all other funds	None (except 1% for certain redemptions within one year of purchase without an initial sales charge1)	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 years2
Class 529-E	None	None	None
Classes T and 529-T3	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

1	18 months for shares purchased on or after August 14, 2017.
2	Effective December 1, 2017.
3	Class T and 529-T shares are not available for purchase.

Holders of all share classes of each fund have equal pro rata rights to the assets, dividends and liquidation proceeds of each fund held. Each share class of each fund 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 and transfer agent 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 of each fund.

28 American Funds Portfolio Series

2. Significant accounting policies

Each fund in the series is an investment company that applies the accounting and reporting guidance issued in Topic 946 by the U.S. Financial Accounting Standards Board. Each fund’s financial statements have been prepared to comply with U.S. generally accepted accounting principles (“U.S. GAAP”). These principles require the series’ 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 funds follow the significant accounting policies 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 funds as of the date the trades are executed. Realized gains and losses from security transactions are determined based on the specific identified cost of the securities. Dividend income is recognized on the ex-dividend date.

Fees and expenses — The fees and expenses of the underlying funds are not included in the fees and expenses reported for each of the funds; however, they are indirectly reflected in the valuation of each of the underlying funds. These fees are included in the net effective expense ratios that are provided as supplementary information in the financial highlights tables.

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 of each fund 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 of each fund.

Dividends and distributions to shareholders — Dividends and distributions to shareholders are recorded on each fund’s ex-dividend date.

3. Valuation

Security valuation — The net asset value of each share class of each fund is calculated based on the reported net asset values of the underlying funds in which each fund invests. The net asset value of each underlying fund is calculated based on the policies and procedures of the underlying fund contained in each underlying fund’s statement of additional information. Generally, the funds and the underlying funds determine the net asset value of each share class as of approximately 4:00 p.m. New York time each day the New York Stock Exchange is open.

Processes and structure — The series’ board of trustees has delegated authority to the series’ 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 with supplemental information to support the changes. The series’ board and audit committee also regularly review reports that describe fair value determinations and methods. 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 series’ investment adviser classifies each fund’s assets and liabilities into three levels based on the method 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. 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. At October 31, 2017, all of the investment securities held by each fund were classified as Level 1.

4. Risk factors

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

Allocation risk — Investments in the fund are subject to risks related to the investment adviser’s allocation choices. The selection of the underlying funds and the allocation of the fund’s assets could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

American Funds Portfolio Series 29

Fund structure — The fund invests in underlying funds and incurs expenses related to the underlying funds. In addition, investors in the fund will incur fees to pay for certain expenses related to the operations of the fund. An investor holding the underlying funds directly and in the same proportions as the fund would incur lower overall expenses but would not receive the benefit of the portfolio management and other services provided by the fund.

Underlying fund risks — Because the fund’s investments consist of underlying funds, the fund’s risks are directly related to the risks of the underlying funds. For this reason, it is important to understand the risks associated with investing in the underlying funds, as described below.

Market conditions — The prices of, and the income generated by, the common stocks, bonds and other securities held by the underlying funds 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 underlying funds 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 stocks — Investing in stocks may involve larger price swings and greater potential for loss than other types of investments. As a result, the value of the underlying funds may be subject to sharp, short-term declines in value. Income provided by an underlying fund may be reduced by changes in the dividend policies of, and the capital resources available at, the companies in which the underlying fund invests.

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.

Investing in income-oriented stocks — Income provided by an underlying 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 underlying fund invests.

Investing in debt instruments — The prices of, and the income generated by, bonds and other debt securities held by an underlying 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. 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 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 will weaken 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. Credit risk is gauged, in part, by the credit ratings of the debt securities in which the underlying 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 underlying funds’ investment adviser relies on its own credit analysts to research issuers and issues in seeking to mitigate various credit and default risks.

Investing in lower rated debt instruments — Lower rated bonds and other lower rated debt securities generally have higher rates of interest and involve greater risk of default or price declines due to changes in the issuer’s creditworthiness than those of higher quality debt securities. The market prices of these securities may fluctuate more than the prices of higher quality debt securities and may decline significantly in periods of general economic difficulty. These risks may be increased with respect to investments in junk bonds.

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.

Currency — The prices of, and the income generated by, many debt securities held by the underlying funds may also be affected by changes in relative currency values. If the U.S. dollar appreciates against foreign currencies, the value in U.S. dollars of an underlying fund’s securities denominated in such currencies would generally fall and vice versa. U.S. dollar-denominated securities of foreign issuers may also be affected by changes in relative currency values.

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 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 an underlying 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 underlying fund’s net asset value. Additionally, there may be increased settlement risks for transactions in local securities.

Investing in securities backed by the U.S. government — Securities backed by the U.S. Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Securities issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are neither issued nor guaranteed by the U.S. government.

Investing in mortgage-related and other asset-backed securities — Mortgage-related securities, such as mortgage-backed securities, and other asset-backed securities, include debt obligations that represent interests in pools of mortgages or other income-bearing assets, such as consumer loans or receivables. Such securities often involve risks that are different from or more acute than the risks associated with investing in other types of debt securities. Mortgage-backed and other asset-backed securities are subject to changes in the payment patterns of borrowers of the underlying debt. When interest rates fall, borrowers are more likely to refinance or prepay their debt before its stated maturity. This may result in the underlying fund having to reinvest the proceeds in lower yielding securities, effectively reducing the underlying fund’s income. Conversely, if interest rates rise and borrowers repay their debt more slowly than expected, the time in which the mortgage-backed and other asset-backed securities are paid off could be extended, reducing the underlying fund’s cash available for reinvestment in higher yielding securities.

Investing in future delivery contracts — An underlying fund may enter into contracts, such as to-be-announced contracts and mortgage dollar rolls, that involve an underlying fund selling mortgage-related securities and simultaneously contracting to repurchase similar securities for delivery at a future date at a predetermined price. This can increase the underlying fund’s market exposure, and the market price of the securities that the underlying fund contracts to repurchase could drop below their purchase price. While an underlying fund can preserve and generate capital through the use of such contracts by, for example, realizing the difference between the sale price and the future purchase price, the income generated by the underlying fund may be reduced by engaging in such transactions. In addition, these transactions may increase the turnover rate of the underlying fund.

Investing in inflation linked bonds — The values of inflation linked bonds generally fluctuate in response to changes in real interest rates — i.e., rates of interest after factoring in inflation. A rise in real interest rates may cause the prices of inflation linked securities to fall, while a decline in real interest rates may cause the prices to increase. Inflation linked bonds may experience greater losses than other debt securities with similar durations when real interest rates rise faster than nominal interest rates. There can be no assurance

American Funds Portfolio Series 31

that the value of an inflation linked security will be directly correlated to changes in interest rates; for example, if interest rates rise for reasons other than inflation, the increase may not be reflected in the security’s inflation measure.

Investing in inflation linked bonds may also reduce an underlying fund’s distributable income during periods of extreme deflation. If prices for goods and services decline throughout the economy, the principal and income on inflation linked securities may decline and result in losses to the underlying fund.

Liquidity risk — Certain underlying fund holdings may be deemed to be less liquid or illiquid because they cannot be readily sold without significantly impacting the value of the holdings. Liquidity risk may result from the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the underlying fund may be unable to sell such holdings when necessary to meet its liquidity needs.

Credit and liquidity support — Changes in the credit quality of banks and financial institutions providing credit and liquidity support features with respect to securities held by the underlying fund could cause the values of these securities to decline.

Investing in municipal securities — The yield and/or value of the fund’s investments in municipal securities may be adversely affected by events tied to the municipal securities markets, which can be very volatile and significantly impacted by unfavorable legislative or political developments and negative changes in the financial conditions of municipal securities issuers and the economy. To the extent the fund invests in obligations of a municipal issuer, the volatility, credit quality and performance of the fund may be adversely impacted by local political and economic conditions of the issuer. For example, a credit rating downgrade, bond default or bankruptcy involving an issuer within a particular state or territory could affect the market values and marketability of many or all municipal obligations of that state or territory. Income from municipal securities held by the fund could also be declared taxable because of changes in tax laws or interpretations by taxing authorities or as a result of noncompliant conduct of a municipal issuer. Additionally, the relative amount of publicly available information about municipal securities is generally less than that for corporate securities.

Investing in similar municipal bonds — Investing significantly in municipal obligations of multiple issuers in the same state or backed by revenues of similar types of projects or industries may make an underlying fund more susceptible to certain economic, political or regulatory occurrences. As a result, the potential for fluctuations in the underlying fund’s share price may increase.

Investing in derivatives — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional cash securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may expose the underlying fund to losses in excess of its initial investment. Derivatives may be difficult for the underlying fund to buy or sell at an opportune time or price and may be difficult to terminate or otherwise offset. The underlying fund’s use of derivatives may result in losses to the underlying fund, and investing in derivatives may reduce the underlying fund’s returns and increase the underlying fund’s price volatility. The underlying fund’s counterparty to a derivative transaction (including, if applicable, the underlying fund’s clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction.

Management — The investment adviser to the fund and to the underlying funds actively manages each underlying fund’s investments. Consequently, the underlying funds are 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 an underlying fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

5. Taxation and distributions

Federal income taxation — Each fund complies with the requirements under Subchapter M of the Internal Revenue Code applicable to mutual funds and each intends to distribute substantially all of its net income and net capital gains each year. The funds are 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 October 31, 2017, none of the funds had a liability for any unrecognized tax benefits. These funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the statements of operations. During the period, none of the funds incurred any interest or penalties.

32 American Funds Portfolio Series

The funds are not subject to examination by U.S. federal tax authorities for tax years before 2013 or by state tax authorities for tax years before 2012.

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 short-term capital gains and losses; capital losses related to sales of certain securities within 30 days of purchase; cost of investments sold and net capital losses. 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 funds for financial reporting purposes. The funds may also designate a portion of the amount paid to redeeming shareholders as distributions for tax purposes.

As of October 31, 2017, the tax basis components of distributable earnings, unrealized appreciation (depreciation) and cost of investment securities for each fund were as follows (dollars in thousands):

Investment advisory services — The series has an investment advisory and service agreement with CRMC. CRMC receives fees from the underlying funds for investment advisory services. These fees are included in the net effective expense ratios that are provided as supplementary information in the financial highlights tables.

American Funds Portfolio Series 37

Miscellaneous fee reimbursements — CRMC reimbursed a portion of miscellaneous fees and expenses of Tax-Exempt Preservation Portfolio. Fees and expenses in Tax-Exempt Preservation Portfolio’s statement of operations are presented gross of the reimbursement from CRMC. The amounts reimbursed by CRMC are reflected as miscellaneous fee reimbursements.

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 series has plans of distribution for all share classes of each fund, 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 October 31, 2017, unreimbursed expenses subject to reimbursement for the funds’ Class A and 529-A shares were as follows (dollars in thousands):

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 $20 billion of the net assets invested in the Class 529 shares of 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 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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of the American Funds Portfolio Series:

We have audited the accompanying statements of assets and liabilities, including the investment portfolios, of the American Funds Portfolio Series comprising the American Funds Global Growth Portfolio, American Funds Growth Portfolio, American Funds Growth and Income Portfolio, American Funds Balanced Portfolio, American Funds Income Portfolio, American Funds Tax-Advantaged Income Portfolio, American Funds Preservation Portfolio, and American Funds Tax-Exempt Preservation Portfolio (the “Series”), as of October 31, 2017, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented. These financial statements and financial highlights are the responsibility of the Series’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Series is not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Series’ internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of investments owned as of October 31, 2017, by correspondence with the custodian and transfer agent; when replies were not received from the transfer agent, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the funds comprising the American Funds Portfolio Series as of October 31, 2017, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.

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 examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period (May 1, 2017, through October 31, 2017).

Actual expenses:

The first line of each share class in the tables on the following pages 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 tables on the following pages 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 F-3 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 tables on the following pages 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 tables 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.

1	The “expenses paid during period” are equal to the “annualized expense ratio,” multiplied by the average account value over the period, multiplied by the number of days in the period, and divided by 365 (to reflect the one-half year period).
2	The “expenses paid during period” and “annualized expense ratio” do not include the expenses of the underlying funds in which each fund invests.
3	The “effective expenses paid during period” are equal to the “effective annualized expense ratio,” multiplied by the average account value over the period, multiplied by the number of days in the period, and divided by 365 (to reflect the one-half year period).

American Funds from Capital Group

The Capital Advantage^SM

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

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 21 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 long-term track record

Equity funds have beaten their Lipper peer indexes in 93% of 10-year periods and 98% of 20-year periods. Fixed income funds have beaten their Lipper indexes in 80% of 10-year periods and 80% of 20-year periods.² Fund management fees have been among the lowest in the industry.³

1	Portfolio manager experience as of December 31, 2016.
2	Based on Class F-2 share results for rolling periods through December 31, 2016. 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. 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.
3	On average, our management fees were in the lowest quintile 73% of the time, based on the 20-year period ended December 31, 2016, versus comparable Lipper categories, excluding funds of funds.

ITEM 2 – Code of Ethics

The Registrant has adopted a Code of Ethics that applies to its Principal Executive Officer and Principal Financial Officer. The Registrant undertakes to provide to any person without charge, upon request, a copy of the Code of Ethics. Such request can be made to American Funds Service Company at 800/421-9225 or to the Secretary of the Registrant, 6455 Irvine Center Drive, Irvine, California 92618.

ITEM 3 – Audit Committee Financial Expert

The Registrant’s board has determined that Laurel B. Mitchell, a member of the Registrant’s audit committee, is an “audit committee financial expert” and "independent," as such terms are defined in this Item. This designation will not increase the designee’s duties, obligations or liability as compared to his or her duties, obligations and liability as a member of the audit committee and of the board, nor will it reduce the responsibility of the other audit committee members. There may be other individuals who, through education or experience, would qualify as "audit committee financial experts" if the board had designated them as such. Most importantly, the board believes each member of the audit committee contributes significantly to the effective oversight of the Registrant’s financial statements and condition.

		2016	$81,000

	Not Applicable
b)  Audit-Related Fees:

d)  All Other Fees:

	2017	None
	The other fees consist of subscription services related to an accounting research tool.

All audit and permissible non-audit services that the Registrant’s audit committee considers compatible with maintaining the independent registered public accounting firm’s independence are required to be pre-approved by the committee.  The pre-approval requirement will extend to all non-audit services provided to the Registrant, the investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Registrant, if the engagement relates directly to the operations and financial reporting of the Registrant. The committee will not delegate its responsibility to pre-approve these services to the investment adviser. The committee may delegate to one or more committee members the authority to review and pre-approve audit and permissible non-audit services.  Actions taken under any such delegation will be reported to the full committee at its next meeting. The pre-approval requirement is waived with respect to non-audit services if certain conditions are met. The pre-approval requirement was not waived for any of the non-audit services listed above provided to the Registrant, adviser and affiliates.

Aggregate non-audit fees paid to the Registrant’s auditors, including fees for all services billed to the Registrant, adviser and affiliates that provide ongoing services to the Registrant, were $1,228,000 for fiscal year 2016 and $1,419,000 for fiscal year 2017. The non-audit services represented by these amounts were brought to the attention of the committee and considered to be compatible with maintaining the auditors’ independence.

ITEM 5 – Audit Committee of Listed Registrants

Not applicable to this Registrant, insofar as the Registrant is not a listed issuer as defined in Rule 10A-3 under the Securities Exchange Act of 1934.

ITEM 6 – Schedule of Investments

Not applicable, insofar as the schedule is included as part of the report to shareholders filed under Item 1 of this Form.

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.

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)(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.
