Portfolio Series^®   Annual report
for the year ended
October 31, 2016

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 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. Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value. For current information and month-end results, visit americanfunds.com.

Here are the total returns on a $1,000 investment with all distributions reinvested for periods ended September 30, 2016 (the most recent calendar quarter-end). Also shown are the expense ratios as of the series prospectus dated January 1, 2017 (unaudited):

Fellow investors:

We are pleased to present the annual report for the American Funds Portfolio Series, for the period ended October 31, 2016. The reporting period saw much volatility, including dramatic reactions to the U.K.’s surprise decision to leave the European Union in June, and uncertainty amid the U.S. presidential campaign. Despite these conditions, all the funds within the series returned positive results. Returns ranged from 5.30% (for American Funds Income Portfolio) to 1.86% (for American Funds Global Growth Portfolio, which invests significantly in issuers outside the U.S.).

The U.S. stock market did well despite increased volatility. U.S. stocks saw modest gains overall midyear, despite weakening economic data and the turmoil caused by the U.K.’s vote to exit the European Union. By the end of the fiscal year, U.S. stocks weakened somewhat amid interest rate worries and disappointing earnings from several companies. Fixed income funds advanced over most of the year, while in the last quarter, those with higher credit exposures fared the best. The euro zone quickly rebounded from the selloff that followed the U.K.’s exit from the European Union. Generally, funds with an income focus, which are more heavily weighted in the higher yielding telecommunications and utilities sectors, tended to outpace those with a growth objective. This trend continued until the last quarter of the year, when these companies’ yields weakened a bit.

As always, we encourage investors to keep short-term results in their proper perspective, especially during periods of market and political volatility.

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. The Committee regularly monitors the Portfolio Series funds.

The economy

The U.S. economy grew at a modest pace over the first half of the fiscal year. However, by the end of the period, real gross domestic product increased at an annual rate of 3.2%, the biggest gain since 2014, and this on top of the previous quarter’s 1.4% gain. This result reflects an increase in personal consumption expenditures (PCE), exports and private inventory investment, among other factors. The U.S. consumer appears in relatively good shape with household debt near 30-year-lows, unemployment levels down and the emergence of the first signs of wage growth.

The stock market

U.S. stocks advanced at the end of the period, having recovered from earlier volatility. Information technology stocks lifted the Standard & Poor’s 500 Composite Index* (a market capitalization-weighted index based on the results of 500 widely held common stocks) to 4.51%. The increase was buoyed by the Federal Reserve’s decision to let interest rates stand at its July and September meetings.

International markets showed mixed results early on, but advanced later. The

American Funds
Portfolio Series

“We created the portfolio series to provide investors with a core of high-quality, actively managed investments that can help them with savings goals like college and retirement. Our approach requires a meticulous examination and selection of the underlying funds. We feel the series simplifies investment complexity for ordinary individuals and families.”

MSCI All Country World ex USA Index*, a leading benchmark for developed and developing markets outside the U.S., registered 0.22% for the period. Japanese companies rebounded from earlier losses, and non-Japan Pacific companies rallied. Companies domiciled in the euro zone rebounded from the selloff that occurred following the Brexit referendum in June, but fell by the end of the year amid continued uncertainty. U.K.-listed companies lagged their euro zone counterparts, in part due to the currency weakness.

The bond market

U.S. bonds were volatile during late 2015, with yields trending higher immediately following the Fed rate hike. By the end of the fiscal year the Bloomberg Barclays U.S. Aggregate Index* (a measure of the broad fixed income investment-grade market of bonds rated BBB/Baa and above) gained 4.37%.

In October 2016, the yield on the bellwether 10-year Treasury note rose 24 basis points to 1.84%. Higher yields across the Treasury curve hurt bond prices in most sectors. Investment-grade corporates declined by 0.81%, while high-yield corporates rose 0.39%. Investment-grade corporate spreads to Treasuries tightened six basis points to end the month at 132 basis points.

Inflation expectations have crept higher over the past few months. Yet Treasury Inflation Protected Securities prices ended October 0.40% lower, due largely to the impact of higher government bond yields. Municipal bonds lost 1.05% in a month of record-setting issuance; the increased supply, in combination with rising Treasury yields, put downward pressure on muni bond prices.

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. Within fixed income, funds with higher credit exposures fared the best.

All equity funds within the series delivered positive results. Toward the end of the fiscal year, higher yielding companies, such as those in the consumer telecommunications and utilities sectors, slightly weakened from earlier advances. This was a drag on the returns of funds with an income focus.

Bond funds experienced the greatest returns and were strengthened by holdings in such underlying funds as American High-Income Trust^®, which led with a gain of 8.36%. Also benefitting the fixed income category was American High-Income Municipal Bond Fund^®, which seeks high-yield, tax-exempt income through bonds and notes, with a gain of 6.72%. American Mutual Fund^®, an equity fund which aims for conservation of capital, also saw a gain of 6.33%. The funds in the series geared toward preservation posted more modest gains, such as The Bond Fund of America^®, at 4.21%.

The table on page 3 shows the lifetime results for the funds (since May 18, 2012). We include in this table the indexes we use to compare our funds to their markets. This year we changed and/or added certain benchmark indexes (indicated with footnote symbols 3 and 4), as we deemed them more representative of the funds’ objectives.

Please keep in mind that this four-and-a-half-year period is still a relatively brief investment time frame. We also encourage investors to bear in mind that the funds in the series are designed as long-term investments.

Moving forward

Strong employment and wage growth are currently supporting consumer health as construction and housing gain momentum. But given that companies in many areas of the market are fully valued, selectivity is important. As always, we take a long-term, research driven approach to investing that has served clients for more than 80 years.

We thank you for your continued interest in the American Funds Portfolio Series and look forward to reporting to you again in six months.

Cordially,

Bradley J. Vogt

American Funds Portfolio Series 25

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 18 share classes consisting of five retail share classes (Classes A, B and C, as well as two F share classes, F-1 and F-2), five 529 college savings plan share classes (Classes 529-A, 529-B, 529-C, 529-E and 529-F-1) and eight retirement plan share classes (Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6). The 529 college savings plan share classes can be used to save for college education. The retirement plan share classes are generally offered only through eligible employer-sponsored retirement plans. The Tax-Advantaged Income Portfolio and Tax-Exempt Preservation Portfolio each have five retail share classes (Classes A, B and C, as well as two F share classes, F-1 and F-2). 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 charge)	None
Classes B and 529-B*	None	Declines from 5% to 0% for redemptions within six years of purchase	Classes B and 529-B convert to Classes A and 529-A, respectively, after eight years
Class C	None	1% for redemptions within one year of purchase	Class C converts to Class F-1 after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	None
Class 529-E	None	None	None
Classes F-1, F-2 and 529-F-1	None	None	None
Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6	None	None	None

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

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

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

26 American Funds Portfolio Series

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.

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 on pages 48 to 62.

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, 2016, all of the investment securities held by each fund were classified as Level 1.

American Funds Portfolio Series 27

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.

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 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.

28 American Funds Portfolio Series

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 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.

Liquidity risk — Certain 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 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 similar municipal bonds — Investing significantly in municipal obligations of 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

American Funds Portfolio Series 29

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 taxable income and net capital gains are distributed.

As of and during the period ended October 31, 2016, none of the funds had a liability for any unrecognized tax benefits. Each fund recognizes 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 significant interest or penalties.

The series is not subject to examination by U.S. federal and state tax authorities for tax years before 2012, the year the series commenced operations.

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.

6. Fees and transactions with related parties

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

Investment advisory services — At the beginning of the reporting period, the series had an investment advisory and service agreement with CRMC that provided for monthly fees, accrued daily. These fees were based on an annual rate of 0.10% of daily net assets. CRMC waived these fees through December 31, 2015. Effective January 1, 2016, CRMC eliminated the management fee. Investment advisory services fees are presented in the statements of operations gross of the waiver from 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 on pages 48 to 62.

Miscellaneous fee reimbursements — CRMC reimbursed a portion of the 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.

American Funds Portfolio Series 35

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, except Class F-2, 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.

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

Administrative services — The series has an administrative services agreement with CRMC for providing administrative services to all of the funds’ share classes. These services include, but are not limited to, coordinating, monitoring, assisting and overseeing third parties that provide services to fund shareholders. CRMC receives administrative services fees of 0.05% of average daily net assets from the Class R-6 shares of the underlying funds for administrative services provided to the series.

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. From November 1, 2015 to June 30, 2016, the quarterly fee was based on a series of decreasing annual rates beginning with 0.10% on the first $30 billion of the net assets invested in Class 529 shares of the American Funds and decreasing to 0.05% on such assets in excess of $70 billion. Effective July 1, 2016, the quarterly fee was amended to annual rates of 0.10% on the first $20 billion of the net assets invested in the Class 529 shares of the American Funds, 0.05% on such assets between $20 billion and $100 billion, and 0.03% on such assets over $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, 2016, 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 its 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, 2016, by correspondence with the custodian and transfer agent; where 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, 2016, 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, 2016, through October 31, 2016).

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 and F-2 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).
4	The “effective annualized expense ratio” reflects the net annualized expense ratio of the class plus the class’s pro-rata share of the weighted average expense ratio of the underlying funds in which it invests. The annualized weighted average expense ratio of the underlying funds for the period reflects the net actual expense ratio of each underlying fund for the period, annualized and weighted for the fund’s relative average investment therein during the period.

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 22 years at our company, reflecting a career commitment to our long-term approach.¹

The Capital System^SM

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.

Superior long-term track record

Our equity funds have beaten their Lipper peer indexes in 91% of 10-year periods and 95% of 20-year periods. Our fixed income funds have beaten their Lipper indexes in 58% of 10-year periods and 58% of 20-year periods.² Our fund management fees have been among the lowest in the industry.³

1	Portfolio manager experience as of December 31, 2015.
2	Based on Class A share results for rolling periods through December 31, 2015. 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).
3	On average, our management fees were in the lowest quintile 68% of the time, based on the 20-year period ended December 31, 2015, 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.

2015 $62,000

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 $1,445,000 for fiscal year 2015 and $1,228,000 for fiscal year 2016. 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

(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.

(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.
