American High-Income Trust^®

Semi-annual report
for the six months ended
March 31, 2017

We believe high-
conviction investing
and diverse
perspectives lead
to better results.

American High-Income Trust seeks to provide you with a high level of current income. Its secondary investment objective is capital appreciation.

This fund is one of more than 40 offered by one of the nation’s largest mutual fund families, American Funds, from Capital Group. For more than 85 years, Capital has invested with a long-term focus based on thorough research and attention to risk.

Fund results shown in this report, unless otherwise indicated, are for Class A shares at net asset value. If a sales charge (maximum 3.75%) had been deducted, the results would have been lower. Results are for past periods and are not predictive of results for future periods. Current and future results may be lower or higher than those shown. Share prices and returns will vary, so investors may lose money. Investing for short periods makes losses more likely. Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value. For current information and month-end results, visit americanfunds.com.

Here are the average annual total returns on a $1,000 investment with all distributions reinvested for periods ended March 31, 2017:

Class A shares	1 year	5 years	10 years
Reflecting 3.75% maximum sales charge	11.82%	4.27%	5.00%

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

The total annual fund operating expense ratio was 0.71% for Class A shares as of the prospectus dated April 7, 2017.

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

The return of principal for bond funds and for funds with significant underlying bond holdings is not guaranteed. Fund shares are subject to the same interest rate, inflation and credit risks associated with the underlying bond holdings. High-yield bonds are subject to greater fluctuations in value and risk of loss of income and principal than investment-grade bonds. Bond ratings, which typically range from AAA/Aaa (highest) to D (lowest), are assigned by credit rating agencies such as Standard & Poor’s, Moody’s and/or Fitch as an indication of an issuer’s creditworthiness. Investing in bonds issued outside the U.S. may be subject to additional risks. They include currency fluctuations, political and social instability, differing securities regulations and accounting standards, higher transaction costs, possible changes in taxation, illiquidity and price volatility. These risks may be heightened in connection with investments in developing countries. Refer to the fund prospectus and the Risk Factors section of this report for more information on these and other risks associated with investing in the fund.

Fellow investors: Strong recent
returns should
be considered in
the context of the
fund’s long-term
objective.  

For the six-month period ended March 31, 2017, American High-Income Trust reported a total return of 4.99%, assuming a 28 cents a share reinvestment of monthly dividends. Shareholders who reinvested dividends received an income return of 2.80% for the period. Those who elected to take their dividends in cash received an income return of 2.77% and saw the value of their holdings increase by 2.16%.

By comparison, the Lipper High Yield Funds Average, a benchmark of similar funds, posted a total return of 3.93%, and the Bloomberg Barclays U.S. Corporate High Yield 2% Issuer Capped Index, an unmanaged non-investment-grade debt index that has no expenses, returned 4.50%.

American High-Income Trust 1

throughout the six-month period covered by this report. The dominant influence on high yield prices during this time frame was the surge in U.S. growth prospects after the presidential election. Other factors included the ongoing recovery in energy and other commodity prices from early-2016 lows and the sustained investor demand for yield due to persistent low interest rates from the world’s central banks.

High-yield bonds as well as equity markets benefited from the post-election confidence; plans to ease regulatory and tax burdens and increase infrastructure spending revived hopes for an acceleration in U.S. economic growth after a long period of slow progress. These proposals, if passed, would boost the prospects for many high yield companies, especially in the industrial, energy and commodity sectors.

The flip side of the stock market rally – a renewed expectation for Federal Reserve rate hikes and inflation – caused a decline in prices for U.S. Treasury and other investment-grade bonds (rated BBB/Baa and above) over the same time period. The higher yielding part of the bond market, however, was far more affected by the prospect for growth – which makes debt easier to service – than incremental rate fears. This is in keeping with the unique nature of the high yield sector, which can behave like bonds or stocks depending on the market environment.

Inside the portfolio

The fund outgained its benchmarks during this period of strong high yield returns. An important contributor to the fund was once again energy- and commodity-related issuers, both of which comprise a large percentage of the high-yield market.

Within the energy ecosystem, the fund’s largest exposure was to pipeline companies, which have proven to be less volatile than energy in general. We believe transport to be a prudent exposure to the energy sector. Our other investments in oil and gas exploration and development companies have been volatile but also did well in this period.

The fund continues to maintain its large exposures in telecommunications and health-care related issuers. Some telecommunications deregulation proposals

The fund’s 30-day yield for Class A shares as of April 30, 2017, calculated in accordance with the U.S. Securities and Exchange Commission (SEC) formula, was 5.10%. The fund’s 12-month distribution rate for Class A shares as of that date was 5.19%. Both reflect the 3.75% maximum sales charge. The SEC yield reflects the rate at which the fund is earning income on its current portfolio of securities while the distribution rate reflects the fund’s past dividends paid to shareholders. Accordingly, the fund’s SEC yield and distribution rate may differ.

being considered by the incoming administration and Congress may benefit some of the fund’s phone and cable holdings in particular. Health care, on the other hand, may come under pressure from various legislative proposals to cut costs or modify coverage. The fund is thus focused on companies that are better equipped, in our view, to weather a change in the regulatory environment.

Looking ahead

The current market consensus for a continuation of solid but constrained U.S. economic growth should continue to be positive for high yield, as it will likely keep defaults under control and support more borrowing, especially among industrial and energy companies. If interest rates and inflation rise along with growth, meanwhile, it should be less of a concern for high yield than for other fixed income markets.

We believe fundamentals support this perspective of a constructive high yield market environment. Defaults continue to be low and there is ample access to capital so that companies can continue to manage their debt as it matures. High yield prices are less attractive than they were six months ago, but are still reasonable relative to long-term averages.

The fund’s strong recent returns – and constructive outlook – should, as always, be considered in the context of the fund’s long-term objective of providing attractive returns and a steady source of income. By that measure, the fund’s shareholders earned an average annual total return of 5.41% (with dividends reinvested) for the past 10-year period ended March 31, 2017.

Investment-grade bonds, by contrast, returned 4.27% for the same 10-year period, as measured by the Bloomberg Barclays U.S. Aggregate Index, which is unmanaged and has no expenses.

As always, we appreciate your continued support and long-term investment perspective.

Sincerely,

 

David C. Barclay
President

1. Organization

American High-Income Trust (the “fund”) is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The fund seeks to provide a high level of current income. Its secondary investment objective is capital appreciation.

The fund has 19 share classes consisting of six retail share classes (Classes A, B and C, as well as three F share classes, F-1, F-2 and F-3), five 529 college savings plan share classes (Classes 529-A, 529-B, 529-C, 529-E and 529-F-1) and eight retirement plan share classes (Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6). The 529 college savings plan share classes can be used to save for college education. The retirement plan share classes are generally offered only through eligible employer-sponsored retirement plans. The fund’s share classes are described further in the following table:

Share class	Initial sales charge	Contingent deferred sales charge upon redemption	Conversion feature
Classes A and 529-A	Up to 3.75%	None (except 1% for certain redemptions within one year of purchase without an initial sales charge)	None
Classes B and 529-B*	None	Declines from 5% to 0% for redemptions within six years of purchase	Classes B and 529-B convert to Classes A and 529-A, respectively, after eight years
Class C	None	1% for redemptions within one year of purchase	Class C converts to Class F-1 after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	None
Class 529-E	None	None	None
Classes F-1, F-2, F-3 and 529-F-1	None	None	None
Classes R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6	None	None	None

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

On January 27, 2017, the fund made an additional retail share class (Class F-3) available for sale pursuant to an amendment to its registration statement filed with the U.S. Securities and Exchange Commission. Refer to the fund’s prospectus for more details.

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

16 American High-Income Trust

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

2. Significant accounting policies

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

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

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

Dividends and distributions to shareholders — Dividends to shareholders are declared daily after the determination of the fund’s net investment income and are paid to shareholders monthly. Distributions to shareholders are recorded on the ex-dividend date.

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

American High-Income Trust 17

3. Valuation

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

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

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

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

Fixed-income class	Examples of standard inputs
All	Benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, spreads and other relationships observed in the markets among comparable securities; and proprietary pricing models such as yield measures calculated using factors such as cash flows, financial or collateral performance and other reference data (collectively referred to as “standard inputs”)
Corporate bonds & notes; convertible securities	Standard inputs and underlying equity of the issuer
Bonds & notes of governments & government agencies	Standard inputs and interest rate volatilities
Mortgage-backed; asset-backed obligations	Standard inputs and cash flows, prepayment information, default rates, delinquency and loss assumptions, collateral characteristics, credit enhancements and specific deal information
Municipal securities	Standard inputs and, for certain distressed securities, cash flows or liquidation values using a net present value calculation based on inputs that include, but are not limited to, financial statements and debt contracts

18 American High-Income Trust

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

Securities with both fixed-income and equity characteristics, or equity securities traded principally among fixed-income dealers, are generally valued in the manner described for either equity or fixed-income securities, depending on which method is deemed most appropriate by the fund’s investment adviser. Interest rate swaps and credit default swaps are generally valued by pricing vendors based on market inputs that include the index and term of index, reset frequency, payer/receiver, currency and pay frequency.

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

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

American High-Income Trust 19

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

Classifications — The fund’s investment adviser classifies the fund’s assets and liabilities into three levels based on the inputs used to value the assets or liabilities. Level 1 values are based on quoted prices in active markets for identical securities. Level 2 values are based on significant observable market inputs, such as quoted prices for similar securities and quoted prices in inactive markets. Certain securities trading outside the U.S. may transfer between Level 1 and Level 2 due to valuation adjustments resulting from significant market movements following the close of local trading. Level 3 values are based on significant unobservable inputs that reflect the investment adviser’s determination of assumptions that market participants might reasonably use in valuing the securities. The valuation levels are not necessarily an indication of the risk or liquidity associated with the underlying investment. For example, U.S. government securities are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market. The following tables present the fund’s valuation levels as of March 31, 2017 (dollars in thousands):

Unobservable inputs — Valuation of the fund’s Level 3 securities is 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 following table provides additional information used by the fund’s investment adviser to fair value the fund’s Level 3 securities (dollars in thousands):

	Value at 3/31/2017		Valuation techniques	Unobservable input(s)	Range	Impact to valuation from an increase in input*
Corporate	$	126,976	Yield analysis	Yield risk premium	100 - 400 bps	Decrease
bonds & notes			Yield to call price	Yield to call	2.5% - 5.0%	Decrease
Common stocks		88,780	Enterprise valuation	EV/EBITDA multiple	5.0x - 11.5x	Increase
			Arms-length transaction	Arms-length transaction	N/A	N/A
			Estimated liquidation proceeds	Discount to reflect timing of receipt and amount of proceeds	25% discount	Decrease
			Equity option value	Equity option value	N/A	N/A
Convertible stocks		44,919	Accreted value (stated value increased by accrued dividends)	Payment-in-kind (PIK) dividend rate	N/A	Increase
	$	260,675

^* This column represents the directional change in fair value of the Level 3 securities that would result in an increase from the corresponding input. A decrease to the unobservable input would have the opposite effect. Significant increases and decreases in these inputs in isolation could result in significantly higher or lower fair value measurements.

Key to abbreviations

EV = Enterprise value

EBITDA = Earnings before income taxes, depreciation and amortization

4. Risk factors

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

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

22 American High-Income Trust

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

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

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. 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. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which the fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund’s investment adviser relies on its own credit analysts to research issuers and issues in seeking to 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.

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.

American High-Income Trust 23

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 fund to losses in excess of its initial investment. Derivatives may be difficult for the fund to buy or sell at an opportune time or price and may be difficult to terminate or otherwise offset. The fund’s use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund’s returns and increase the fund’s price volatility. The fund’s counterparty to a derivative transaction (including, if applicable, the 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.

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 the fund. The risks of investing outside the U.S. may be heightened in connection with investments in emerging markets.

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

5. Certain investment techniques

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

24 American High-Income Trust

Unfunded commitments — The fund has participated in a transaction that involves unfunded commitments, which may obligate the fund to purchase additional shares of the applicable issuer. Under the terms of the commitments, which will expire no later than April 1, 2021, the maximum potential exposure as of March 31, 2017, was $3,916,000. Should such commitments become due in full, these amounts would represent .02% of the net assets of the fund as of March 31, 2017.

The fund has also participated in other transactions, which may obligate the fund to lend additional sums based upon the terms of a loan agreement. As of March 31, 2017, the fund’s maximum exposure of unfunded loan commitments was $547,000, which would represent less than .01% of the net assets of the fund should such commitments become due. Unrealized appreciation of $7,000 on this unfunded loan commitment is included in other payables in the fund’s statement of assets and liabilities and net unrealized appreciation on investments in the fund’s statement of operations.

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

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

On a daily basis, the fund’s investment adviser records daily interest accruals related to the exchange of future payments as a receivable and payable in the fund’s statement of assets and liabilities. The fund also pays or receives a “variation margin” based on the increase or decrease in the value of the interest rate swaps, including accrued interest, and records variation margin on interest rate swaps in the statement of assets and liabilities. The fund records realized gains and losses on both the net accrued interest and any gain or loss recognized at the time the interest rate swap is closed or expires. Net realized gains or losses, as well as any net unrealized appreciation or depreciation, from interest rate swaps are recorded in the fund’s statement of operations. The average month-end notional amount of interest rate swaps while held was $126,857,000.

Credit default swap indices — The fund has entered into centrally cleared credit default swap agreements on credit indices (“CDSI”) that involve one party (the protection buyer) making a stream of payments to another party (the protection seller) in exchange for the right to receive a specified return upon the occurrence of a credit event, such as a default

American High-Income Trust 25

or restructuring, with respect to any of the underlying issuers (reference obligations) in the referenced index. The fund’s investment adviser uses credit default swaps to assume exposure to a diversified portfolio of credits or to hedge against existing credit risks.

CDSI are portfolios of credit instruments or exposures designed to be representative of some part of the credit market, such as the high-yield or investment-grade credit market. CDSI are generally traded using standardized terms, including a fixed spread and standard maturity dates, and reference all the names in the index. If there is a credit event, it is settled based on that name’s weight in the index. The composition of the underlying issuers or obligations within a particular index may change periodically, usually every six months. A specified credit event may affect all or individual underlying reference obligations included in the index, and will be settled based upon the relative weighting of the affected obligation(s) within the index. The value of each CDSI can be used as a measure of the current payment/performance risk of the CDSI and represents the likelihood of an expected liability or profit should the notional amount of the CDSI be closed or sold as of the period end. An increasing value, as compared to the notional amount of the CDSI, represents a deterioration of the referenced indices’ credit soundness and a greater likelihood of risk of default or other credit event occurring as defined under the terms of the agreement. When the fund provides sell protection, its maximum exposure is the notional amount of the credit default swap agreement.

Upon entering into a centrally cleared CDSI contract, the fund is required to deposit with a derivatives clearing member (“DCM”) in a segregated account in the name of the DCM an amount of cash, U.S. government securities or other liquid securities, which is known as “initial margin.” Generally, the initial margin required for a particular credit default swap is set and held as collateral by the clearinghouse on which the contract is cleared. The amount of initial margin required may be significantly modified from time to time by the clearinghouse during the term of the contract. Securities deposited as initial margin are designated on the investment portfolio.

On a daily basis, interest accruals related to the exchange of future payments are recorded as a receivable and payable in the fund’s statement of assets and liabilities. The fund also pays or receives a “variation margin” based on the increase or decrease in the value of the CDSI, and records variation margin in the statement of assets and liabilities. The fund records realized gains and losses on both the net accrued interest and any gain or loss recognized at the time the swap is closed or expires. Net realized gains or losses, as well as any net unrealized appreciation or depreciation, from credit default swaps are recorded in the fund’s statement of operations. The average month-end notional amount of credit default swaps while held was $213,903,000.

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

Collateral — The fund participates in a collateral program due to its use of interest rate swaps and credit default swaps. For interest rate swaps and credit default swaps, the program calls for the fund to pledge collateral for initial and variation margin by contract. The purpose of the collateral is to cover potential losses that could occur in the event that either party cannot meet its contractual obligations.

6. Taxation and distributions

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

As of and during the period ended March 31, 2017, the fund did not have a liability for any unrecognized tax benefits. The fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the statement of operations. During the period, the fund did not incur any interest or penalties.

American High-Income Trust 27

The fund is not subject to examination by U.S. federal tax authorities for tax years before 2012, by state tax authorities for tax years before 2011 and by tax authorities outside the U.S. for tax years before 2014.

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

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

The components of distributable earnings on a tax basis are reported as of the fund’s most recent year-end. As of September 30, 2016, the components of distributable earnings on a tax basis were as follows (dollars in thousands):

Undistributed ordinary income				$	26,804
Capital loss carryforward:
No expiration	$	(1,449,835	)
Expiring 2018*		(209,244	)		(1,659,079	)

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

Under the Regulated Investment Company Modernization Act of 2010 (the “Act”), net capital losses recognized after September 30, 2011, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

7. Fees and transactions with related parties

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

Investment advisory services — The fund has an investment advisory and service agreement with CRMC that provides for monthly fees accrued daily. These fees are based on a series of decreasing annual rates beginning with 0.300% on the first $60 million of

American High-Income Trust 29

daily net assets and decreasing to 0.132% on such assets in excess of $21 billion. The agreement also provides for monthly fees, accrued daily, based on a series of decreasing rates beginning with 3.00% on the first $8,333,333 of the fund’s monthly gross income and decreasing to 1.50% on such income in excess of $50,000,000. For the six months ended March 31, 2017, the investment advisory services fee was $23,874,000, which was equivalent to an annualized rate of 0.282% of average daily net assets.

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

Distribution services — The fund has plans of distribution for all share classes, except Class F-2, F-3, R-5E, R-5 and R-6 shares. Under the plans, the board of trustees approves certain categories of expenses that are used to finance activities primarily intended to sell fund shares and service existing accounts. The plans provide for payments, based on an annualized percentage of average daily net assets, ranging from 0.30% to 1.00% as noted in this section. In some cases, the board of trustees has limited the amounts that may be paid to less than the maximum allowed by the plans. All share classes with a plan may use up to 0.25% of average daily net assets to pay service fees, or to compensate AFD for paying service fees, to firms that have entered into agreements with AFD to provide certain shareholder services. The remaining amounts available to be paid under each plan are paid to dealers to compensate them for their sales activities.

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 March 31, 2017, there were no unreimbursed expenses subject to reimbursement for Class A or 529-A shares.

Share class	Currently approved limits			Plan limits

Transfer agent services — The fund has a shareholder services agreement with AFS under which the fund compensates AFS for providing transfer agent services to each of the fund’s share classes. These services include recordkeeping, shareholder

30 American High-Income Trust

communications and transaction processing. In addition, the fund reimburses AFS for amounts paid to third parties for performing transfer agent services on behalf of fund shareholders.

Administrative services — The fund has an administrative services agreement with CRMC under which the fund compensates CRMC for providing administrative services to Class A, C, F, 529 and R shares. These services include, but are not limited to, coordinating, monitoring, assisting and overseeing third parties that provide services to fund shareholders. Under the agreement, Class A shares pay an annual fee of 0.01% and Class C, F, 529 and R shares pay an annual fee of 0.05% of their respective average daily net assets.

529 plan services — Each 529 share class is subject to service fees to compensate the Virginia College Savings Plan (“Virginia529“) for its oversight and administration of the 529 college savings plan. The quarterly fee is based on a series of decreasing annual rates beginning with 0.10% on the first $20 billion of the net assets invested in the Class 529 shares of the American Funds and decreasing to 0.03% on such assets in excess of $100 billion. The fee for any given calendar quarter is accrued and calculated on the basis of the average net assets of Class 529 shares of the American Funds for the last month of the prior calendar quarter. The fee is included in other expenses in the fund’s statement of operations. Virginia529 is not considered a related party to the fund.

Trustees’ deferred compensation — Trustees who are unaffiliated with CRMC may elect to defer the cash payment of part or all of their compensation. These deferred amounts, which remain as liabilities of the fund, are treated as if invested in shares of the fund or other American Funds. These amounts represent general, unsecured liabilities of the fund and vary according to the total returns of the selected funds. Trustees’ compensation of $79,000 in the fund’s statement of operations reflects $63,000 in current fees (either paid in cash or deferred) and a net increase of $16,000 in the value of the deferred amounts.

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

Security transactions with related funds — The fund may purchase from, or sell securities to, other funds managed by CRMC (or funds managed by certain affiliates of CRMC) under procedures adopted by the fund’s board of trustees.

Interfund lending — Pursuant to an exemptive order issued by the SEC, the fund, along with other CRMC-managed funds (or funds managed by certain affiliates of CRMC), may participate in an interfund lending program. The program provides an alternate credit facility that permits the funds to lend or borrow cash for temporary purposes directly to or from one another, subject to the conditions of the exemptive order. The fund did not lend or borrow cash through the interfund lending program at any time during the six months ended March 31, 2017.

8. Committed line of credit

The fund participates with other funds managed by CRMC (or funds managed by certain affiliates of CRMC) in a $1 billion credit facility (the “line of credit”) to be utilized for temporary purposes to support shareholder redemptions. The fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which are reflected in other expenses in the fund’s statement of operations. The fund did not borrow on this line of credit at any time during the six months ended March 31, 2017.

Expense example unaudited

As a fund shareholder, you incur two types of costs: (1) transaction costs, such as initial sales charges on purchase payments and contingent deferred sales charges on redemptions (loads), and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund so you can compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period (October 1, 2016, through March 31, 2017).

Actual expenses:

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

Hypothetical example for comparison purposes:

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

Notes:

Retirement plan participants may be subject to certain fees charged by the plan sponsor, and Class F-1, F-2, F-3 and 529-F-1 shareholders may be subject to fees charged by financial intermediaries, typically ranging from 0.75% to 1.50% of assets annually depending on services offered. You can estimate the impact of these fees by adding the amount of the fees to the total estimated expenses you paid on your account during the period as calculated above. In addition, your ending account value would be lower by the amount of these fees.

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

Approval of Investment Advisory and Service Agreement

American High-Income Trust’s board has approved the fund’s Investment Advisory and Service Agreement (the “agreement”) with Capital Research and Management Company (“CRMC”) for an additional one-year term through April 30, 2018. The board approved the agreement following the recommendation of the fund’s Contracts Committee (the “committee”), which is composed of all of the fund’s independent board members. The board and the committee determined that the 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 the 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 following factors, 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 CRMC and the Capital Group 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 fund under the agreement and other agreements, as well as the benefits to fund 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 the fund and its shareholders.

2. Investment results

The board and the committee considered the investment results of the fund in light of its objectives of providing a high level of current income and, secondarily, capital appreciation. They compared the fund’s investment results with those of other relevant funds (including the other funds that currently 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, over various periods through October 31, 2016. This report, including the letter to shareholders and related disclosures, contains certain information about the fund’s

46 American High-Income Trust

investment results. The board and the committee reviewed the fund’s investment results measured against the Lipper High Yield Funds Average and the Bloomberg Barclays U.S. Corporate High Yield 2% Issuer Capped Index. They noted that the investment results of the fund were above those of the Lipper average for the year-to-date, one-year and lifetime periods (while below the Lipper average for the three-year, five-year and 10-year periods), and below the Bloomberg Barclays index for all periods considered. The board and committee also discussed certain actions being taken by CRMC to improve the fund’s relative results. The board and the committee concluded that the fund’s investment results have been satisfactory for renewal of the agreement and that CRMC’s record in managing the fund indicated that its continued management should benefit the fund and its shareholders.

3. Advisory fees and total expenses

The board and the committee compared the advisory fees and total expense levels of the fund to those of other relevant funds. They observed that the fund’s advisory fees generally compared favorably to those of other similar funds included in the Lipper High Yield Funds Average category and expenses were in line with the median of such funds. The board and the committee also considered the breakpoint discounts in the fund’s advisory fee structure that reduce the level of fees charged by CRMC to the fund as fund assets increase. In addition, they reviewed information regarding the effective advisory fees charged to non-mutual fund 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, regulatory and market differences between advising the fund and the other clients. The board and the committee concluded that the fund’s cost structure was fair and reasonable in relation to the services provided, and that the 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 the fund and 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 fund’s principal underwriter, an affiliate of CRMC; and possible ancillary benefits to CRMC and its institutional management affiliates in managing other investment vehicles. The board and the committee reviewed CRMC’s portfolio trading practices, noting the benefits CRMC receives from the research obtained with commissions from portfolio transactions made on behalf of the fund. The board and the

American High-Income Trust 47

committee took these ancillary benefits into account in evaluating the reasonableness of the advisory fees and other amounts paid to CRMC by the fund.

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 related cost allocation methodology as well as its 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. They further considered the breakpoint discounts in the fund’s advisory fee structure. The board and the committee concluded that the fund’s advisory fee structure reflected a reasonable sharing of benefits between CRMC and the fund’s shareholders.

American Funds from Capital Group

The Capital Advantage^SM

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

Aligned with investor success

We base our decisions on a long-term perspective, which we believe aligns our goals with the interests of our clients. Our portfolio managers average 27 years of investment experience, including 21 years at our company, reflecting a career commitment to our long-term approach.¹

The Capital System^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.

American Funds’ superior long-term track record

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

1	Portfolio manager experience as of December 31, 2016.
2	Based on Class F-2 share results for rolling periods through December 31, 2016. Periods covered are the shorter of the fund’s lifetime or since the comparable Lipper index inception date (except Capital Income Builder and SMALLCAP World Fund, for which the Lipper average was used). Expenses differ for each share class, so results will vary. Class F-2 shares were first offered on August 1, 2008. Class F-2 share results prior to the date of first sale are hypothetical based on Class A share results without a sales charge, adjusted for typical estimated expenses. Results for certain funds with an inception date after August 1, 2008, also include hypothetical returns because those funds’ Class F-2 shares sold after the funds’ date of first offering. Please see americanfunds.com for more information on specific expense adjustments and the actual dates of first sale.
3	On average, our management fees were in the lowest quintile 73% of the time, based on the 20-year period ended December 31, 2016, versus comparable Lipper categories, excluding funds of funds.

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

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

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

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

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

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

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

There have been no material changes to the procedures by which shareholders may recommend nominees to the Registrant’s board of 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.
