Semi-annual report
for the six months ended
April 30, 2015

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 80 years, Capital has invested with a long-term focus based on thorough research and attention to risk.

Fund results shown in this report, unless otherwise indicated, are for Class A shares at net asset value. If a sales charge 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 March 31, 2015 (the most recent calendar quarter-end). Also shown are the gross and net expense ratios as of the series prospectus dated January 1, 2015:

American Funds Tax-Exempt Preservation Portfolio^SM	1.32		1.50		0.87		0.75

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 series’ investment adviser is currently waiving its management fee of 0.10%, and reimbursing a portion of other expenses in all share classes for Tax-Exempt Preservation Portfolio. In addition, the investment adviser has in the past reimbursed certain expenses for Preservation Portfolio. Investment results and net expense ratios shown reflect the waiver and/or reimbursements, without which the results would have been lower and the expenses would have been higher. 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. The waiver and reimbursements will remain in effect at least through December 31, 2015. After that time, the adviser may elect at its discretion to extend, modify or terminate the reimbursements. The waiver may only be modified or terminated with the approval of the series board.

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.

Fellow investors:

It’s our pleasure to present the semi-annual report for American Funds Portfolio Series for the six months ended April 30, 2015. Each fund in the series advanced, with returns ranging from 0.53% to 6.10%. Although we’re gratified that the results were positive, we ask investors to put them in context. Six months is a very limited time period; investors are best served by maintaining a long-term investment viewpoint.

About the series

The series offers 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. The funds can be used individually or in combination, based on an investor’s needs, risk tolerance and time horizon.

The series was created by our Portfolio Oversight Committee, a group of investment professionals with varied backgrounds, differing investment approaches and decades of experience. The Committee regularly monitors all Portfolio Series funds. They not only look at the funds’ returns, but also the constituent pieces of the portfolios and how they’ve interacted. In January, American Funds Global Balanced Fund^SMwas added to American Funds Balanced Portfolio^SMto help enhance diversification.

The economy

Most economic indicators in the U.S were favorable during the reporting period. The recovery continued at an uneven pace, weighed down by a number of issues, such as harsh winter weather, a strengthening dollar and low oil prices. The U.S. gross domestic product (GDP) moved up 2.2% in the fourth quarter of 2014, following a very brisk 5.0% increase in the prior three months. Estimated GDP declined 0.7% for the first quarter. Steady job growth over the period drove the unemployment rate down to 5.4% at the end of April. Inflation remained in check, with the Consumer Price Index, a key measure of inflation, declining 0.2% year-over-year as of April 30, 2015. World economies were mixed, with developed markets posting generally favorable results, thanks to ongoing support from central banks.

The stock market

U.S. stocks advanced for the six-month period, with Standard & Poor’s 500 Composite Index (a market capitalization-weighted index based on the results of 500 widely held common stocks) gaining 4.39%. Results were particularly strong during the final quarter of 2014, as economic data and corporate earnings supported equity prices. International markets were generally positive, with the MSCI All Country World ex USA Index, a leading benchmark for developed markets outside North America,

American Funds Portfolio Series

advancing 5.56%* for the period. All of the indexes shown in this report are unmanaged and, therefore, have no sales charges or expenses. Investors cannot directly invest in an index.

The bond market

The Federal Reserve ended its quantitative easing program — a tool it had applied to help support the economy — in October. The Fed maintained its short-term federal funds interest rate target near zero, where it has been since December 2008. Fed Chair Janet Yellen stated that potential rate increases would be considered on a “meeting-by-meeting basis,” and indicated the Fed would take a balanced approach in raising rates, stating that even after the initial increase in the target funds rate, “our policy is likely to remain highly accommodative.” Amid uncertainty about the start date of increases, as well as the subsequent pace of any hikes, the overall bond market was up during the reporting period, with the Barclays U.S. Aggregate Index (a measure of the broad fixed-income investment-grade market of bonds rated BBB/Baa and above) posting a 2.06% return. While most areas of the bond market advanced, higher rated bonds led the way, with the Barclays U.S. Corporate Investment Grade Index increasing 2.35%.

How the series fared

All eight funds in the series posted positive results. The strongest returns were attained by those funds with a growth orientation, which benefitted from holding underlying funds with a growth focus, such as New Perspective Fund,^® which invests in multinational companies based in both the United States and overseas. SMALLCAP World Fund^® was additive, as stocks of smaller companies rallied. The funds in the series geared toward preservation posted slight gains as they worked toward their objective of maintaining the value of their assets.

The table on page 3 shows the lifetime results for the funds (since May 18, 2012). Please keep in mind that this less-than-three-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.

Moving forward

The improving employment picture, benign inflation and opportunity for an accelerating growth rate in the second half of 2015 provide a favorable backdrop for continued investment. But after several years of solid gains, investors should temper expectations. We remain watchful of the pace of the U.S. recovery, and geopolitical risks in the Middle East.

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
Vice Chairman of the Board

Walter R. Burkley

President

1. Organization

American Funds Portfolio Series (the “series”) is registered under the Investment Company Act of 1940 as an open-end, diversified 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 the 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 17 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 seven retirement plan share classes (Classes R-1, R-2, R-2E, R-3, R-4, 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 B and 529-B shares of the funds 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.

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. 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 with brokers. 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 and interest income is recognized on an accrual basis.

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 41 to 61.

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 April 30, 2015, 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.

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.

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, interest rate and commodity price fluctuations.

Issuer risks — The prices of, and the income generated by, securities held by the underlying funds may also 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 fund’s 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 lower quality, higher yielding debt securities rated Ba1 or below and BB+ or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser or unrated but determined by the investment adviser to be of equivalent quality, which securities are sometimes referred to as “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

22	American Funds Portfolio Series

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.

Investing outside the U.S. — Securities of issuers domiciled outside the U.S., or with significant operations 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 are domiciled or operate. 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. 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 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.

Thinly traded securities — There may be little trading in the secondary market for particular bonds or other debt securities, which may make them more difficult to value, acquire or sell.

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.

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 April 30, 2015, 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; deferred expenses; 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 components of distributable earnings on a tax basis are reported as of the funds’ most recent year-end. As of October 31, 2014, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

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

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 — The series has an investment advisory and service agreement with CRMC that provides for monthly fees, accrued daily. These fees are based on an annual rate of 0.10% of daily net assets. CRMC is currently waiving these fees. This waiver can only be modified or terminated with the approval of the series’ board of trustees. 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 41 to 61.

Other reimbursements — CRMC has agreed to reimburse a portion of the fees and expenses of Tax-Exempt Preservation Portfolio during its startup period. At its discretion, the adviser may elect to extend, modify or terminate the reimbursements. Fees and expenses in the statements of operations are presented gross of the reimbursement from CRMC. The amounts reimbursed by CRMC are reflected as other reimbursements.

28	American Funds Portfolio Series

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-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 B and 529-B		1.00			1.00
Classes C, 529-C and R-1		1.00			1.00
Class R-2		0.75			1.00
Class R-2E		0.60			0.85
Classes 529-E and R-3		0.50			0.75
Classes F-1, 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 limit of 0.30% is not exceeded. As of April 30, 2015, unreim-bursed expenses subject to reimbursement for the funds’ Class A and 529-A shares were as follows (dollars in thousands):

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

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 (November 1, 2014, through April 30, 2015).

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 entitled “Expenses paid during period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes:

The second line of each share class in the 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.

Approval of Investment Advisory and Service Agreement

The American Funds Portfolio Series’ board has approved renewal of the series’ Investment Advisory and Service Agreement (the “agreement”) with Capital Research and Management Company (“CRMC”) through January 31, 2016. The board approved the agreement following the recommendation of the series’ Contracts Committee (the “committee”), which is composed of all of the series’ independent board members. The board and the committee determined that each fund’s advisory fee structure was fair and reasonable in relation to the services provided and that approving the agreement was in the best interests of each fund and its shareholders.

In reaching this decision, the board and the committee took into account information furnished to them throughout the year and otherwise provided to them, as well as information prepared specifically in connection with their review of the agreement, and were advised by their independent counsel. They considered the factors discussed below, among others, but did not identify any single issue or particular piece of information that, in isolation, was the controlling factor, and each board and committee member did not necessarily attribute the same weight to each factor.

1. Nature, extent and quality of services

The board and the committee considered the depth and quality of CRMC’s investment management process, including its global research capabilities; the experience, capability and integrity of its senior management and other personnel; the low turnover rates of its key personnel; the overall financial strength and stability of its organization; and the ongoing evolution of CRMC’s organizational structure designed to maintain and strengthen these qualities. The board and the committee also considered the nature, extent and quality of administrative, compliance and shareholder services provided by CRMC to the funds under each fund’s agreement and other agreements, as well as the benefits to each fund’s shareholders from investing in a fund that is part of a large family of funds. The board and the committee concluded that the nature, extent and quality of the services provided by CRMC have benefited and should continue to benefit each fund and its shareholders.

2. Investment results

The board and the committee considered the investment results of each fund in light of its objective. They compared each fund’s investment results with those of other relevant funds (including funds that form the basis of the Lipper index for the category in which the fund is included), and data such as relevant market and fund indexes, for the three-month, six-month, one-year and since-inception periods ended June 30, 2014. This report, including the letter to shareholders and related disclosures, contains certain information about each fund’s investment results.

American Funds Global Growth Portfolio seeks to provide long-term growth of capital. The board and the committee reviewed the fund’s investment results measured against (i) the MSCI All Country World Index, (ii) the Lipper Global Funds Index (the Lipper category that includes the fund) and (iii) the Morningstar U.S. Open End World Stock Category (the Morningstar category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than all of the comparisons for the one-year and since-inception periods except the Lipper Index for the since-inception period, although the fund’s investment results were below all of the comparisons for the three- and six-month periods.

American Funds Growth Portfolio seeks to provide long-term growth of capital. The board and the committee reviewed the fund’s investment results measured against (i) the S&P 500 Index, (ii) the Lipper Growth Funds Index (the Lipper category that includes the fund) and (iii) the Morningstar U.S. Open End World Stock Category (the Morningstar category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than the Morningstar Category for all of the periods, although they were lower than the other comparisons for all periods except the S&P 500 Index for the one-year period.

American Funds Growth and Income Portfolio seeks to provide long-term growth of capital while providing current income. The board and the committee reviewed the fund’s investment results measured against (i) the S&P 500 Index, (ii) the Lipper Growth and Income Funds Index (the Lipper category that includes the fund) and (iii) the Morningstar U.S. Open End Aggressive Allocation Category (the Morningstar

American Funds Portfolio Series

category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than all of the comparisons except the S&P 500 for all periods and the Lipper Index for the since-inception period.

American Funds Balanced Portfolio seeks to provide current income and long-term growth of capital and income. The board and the committee reviewed the fund’s investment results measured against (i) the S&P 500 Index, (ii) the Lipper Balanced Funds Index (the Lipper category that includes the fund) and (iii) the Morningstar U.S. Open End Moderate Allocation Category (the Morningstar category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than the Lipper Index and Morningstar Category for the one-year and since-inception periods, although they were lower than the S&P Index for those periods and for all comparisons for the three-month and six-month periods.

American Funds Income Portfolio seeks to provide current income and, secondarily, long-term growth of capital. The board and the committee reviewed the fund’s investment results measured against (i) the S&P 500 Index, (ii) the Lipper Income Funds Index (the Lipper category that includes the fund) and (iii) the Morningstar U.S. Open End Conservative Allocation Category (the Morningstar category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than the Lipper Index and Morningstar Category for all of the periods, although they were lower than the S&P Index for all periods.

American Funds Tax-Advantaged Income Portfolio seeks to provide current income, a portion of which is exempt from regular federal income tax, while secondarily striving for long-term growth of capital. The board and the committee reviewed the fund’s investment results measured against (i) the Barclays Municipal Bond Index, (ii) the Lipper Income Funds Index (the Lipper category that includes the fund) and (iii) the Morningstar U.S. Open End Conservative Allocation Category (the Morningstar category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than all of the comparisons.

American Funds Preservation Portfolio seeks to provide current income, consistent with preservation of capital. The board and the committee reviewed the fund’s investment results measured against (i) the Barclays U.S. Government/Credit 1-7 Years ex BBB Index, (ii) the Lipper Short-Intermediate Investment Grade Debt Funds Index (the Lipper category that includes the fund) and (iii) the Morningstar U.S. Open End Intermediate-Term Bond Category (the Morningstar category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than all of the comparisons except the Barclays for the since-inception period, the Lipper for the one-year, three- and six-month, and since-inception periods, and the Morningstar for the one-year, three- and six-month, and since-inception periods.

American Funds Tax-Exempt Preservation Portfolio seeks to provide current income that is exempt from regular federal income tax, consistent with preservation of capital. The board and the committee reviewed the fund’s investment results measured against (i) the Barclays Municipal Short-Intermediate 1-10 Years Index, (ii) the Lipper Intermediate Municipal Debt Funds Index (the Lipper category that includes the fund)

72	American Funds Portfolio Series

and (iii) the Morningstar U.S. Open End Municipal National Intermediate Bond Category (the Morningstar category is comprised of a group of similar funds whose results are averaged). They noted that the fund’s investment results were higher than all of the comparisons for the since-inception period and higher than the Barclays Index for all periods, although they were lower than the Lipper Index and Morningstar Category for the one-year, three-month and six-month periods.

The board and the committee concluded that in view of the funds’ short history, each fund’s investment results have been satisfactory and that CRMC’s record in managing the funds indicated that its continued management should benefit each fund and its shareholders.

3. Advisory fees and total expenses

The board and the committee compared the total expense levels of each fund to those of other relevant funds. They observed that each fund’s expenses were less than the median and average expenses of those of the other funds included in its Lipper category described above.

The board and the committee also reviewed the advisory fee schedule of the funds (including the fees and expenses of the underlying American Funds in which the funds invest) compared to those of other relevant funds. The board and the committee noted CRMC’s waiver of the entire advisory fee payable by the funds under the agreement and CRMC’s commitment not to remove the waiver without board approval. In addition, they reviewed information regarding the effective advisory fees charged to other clients by CRMC and its affiliates. They noted that, to the extent there were differences between the advisory fees paid by the fund and the advisory fees paid by those clients, the differences appropriately reflected the investment, operational and regulatory differences between advising the fund and the other clients. The board and the committee concluded that each fund’s cost structure was fair and reasonable in relation to the services provided, and that each fund’s shareholders receive reasonable value in return for the advisory fees and other amounts paid to CRMC by the fund.

4. Ancillary benefits

The board and the committee considered a variety of other benefits that CRMC and its affiliates receive as a result of CRMC’s relationship with each fund and the other American Funds, including fees for administrative services provided to certain share classes; fees paid to CRMC’s affiliated transfer agent; sales charges and distribution fees received and retained by the funds’ principal underwriter, an affiliate of CRMC; and possible ancillary benefits to CRMC and its institutional management affiliates in managing other investment accounts. The board and the committee reviewed CRMC’s portfolio trading practices, noting that while CRMC received the benefit of research provided by broker-dealers executing portfolio transactions on behalf of each fund, it did not obtain third-party research or other services in return for allocating brokerage to such broker-dealers. The board and the committee took these ancillary benefits into account in evaluating the reasonableness of the advisory fees and other amounts paid to CRMC by the funds.

American Funds Portfolio Series

5. Adviser financial information

The board and the committee reviewed information regarding CRMC’s costs of providing services to the American Funds, including personnel, systems and resources of investment, compliance, trading, accounting and other administrative operations. They considered CRMC’s costs and willingness to invest in technology, infrastructure and staff to maintain and expand services and capabilities, respond to industry and regulatory developments, and attract and retain qualified personnel. They noted information regarding the compensation structure for CRMC’s investment professionals. The board and the committee also compared CRMC’s profitability and compensation data to the reported results and data of several large, publicly held investment management companies. The board and the committee noted the competitiveness and cyclicality of both the mutual fund industry and the capital markets, and the importance in that environment of CRMC’s long-term profitability for maintaining its independence, company culture and management continuity. The board and the committee concluded that each fund’s advisory fee structure reflected a reasonable sharing of benefits between CRMC and the funds’ shareholders.

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
	Our investment process, The Capital System, combines individual accountability with teamwork. Each fund is 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 96% of 20-year periods. Our fixed-income funds have beaten their Lipper indexes in 54% of 10-year periods and 57% of 20-year periods.²Our fund management fees have been among the lowest in the industry.³

	¹	Portfolio manager experience as of December 31, 2014.
	²	Based on Class A share results for rolling periods through December 31, 2014. Periods covered are the shorter of the fund’s lifetime or since the comparable Lipper index inception date (except SMALLCAP World Fund, for which the Lipper average was used).
	³	On average, our management fees were in the lowest quintile 70% of the time, based on the 20-year period ended December 31, 2014, versus comparable Lipper categories, excluding funds of funds.

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 our internal control over financial reporting during the quarter ended April 30, 2015, which were identified in connection with management's evaluation required by paragraph (d) of Rule 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting, other than as provided below.

Effective November 10, 2014, the American Funds Portfolio Series’ investment adviser implemented a new accounting system. In connection with introducing this new system, additional automated and manual controls were implemented and some existing controls were modified. None of these changes were in response to any identified deficiency or weakness in the American Funds Portfolio Series’ 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.
