American Funds Short-Term Tax-Exempt Bond Fund

Investment objective The fund’s investment objective is to provide you with current income exempt from regular federal income tax, consistent with the maturity and quality standards described in this prospectus, and to preserve capital.

Fees and expenses of the fund This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. In addition to the fees and expenses described below, you may also be required to pay brokerage commissions on purchases and sales of Class F-2 or F-3 shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $500,000 in American Funds. More information about these and other discounts is available from your financial professional, in the “Sales charge reductions and waivers” sections on page 45 of the prospectus and on page 86 of the fund’s statement of additional information, and in the sales charge waiver appendix to this prospectus.

* A contingent deferred sales charge of 1.00% applies on certain redemptions made within 18 months following purchases of $1 million or more made without an initial sales charge. Contingent deferred sales charge is calculated based on the lesser of the offering price and market value of shares being sold.

Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. You may be required to pay brokerage commissions on your purchases and sales of Class F-2 or F-3 shares of the fund, which are not reflected in the example. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 34% of the average value of its portfolio.

Principal investment strategies Under normal circumstances, the fund will invest at least 80% of its assets in, or derive at least 80% of its income from, securities that are exempt from regular federal income tax and that do not subject you to federal alternative minimum tax. The fund may also invest up to 20% of its assets in securities that may subject you to federal alternative minimum tax. The fund invests primarily in debt securities rated AA- or better or Aa3 or better by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. The fund may also invest in debt securities rated A- or better or A3 or better by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. Some of the securities in which the fund invests may have credit and liquidity support features, including guarantees and letters of credit. The fund’s aggregate portfolio will have a dollar-weighted average effective maturity no greater than three years.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers who decide how their respective segments will be invested.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is by analyzing various factors, which may include the credit strength of the issuer, prices of similar securities issued by comparable issuers, anticipated changes in interest rates, general market conditions and other factors pertinent to the particular security being evaluated. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

Principal risks This section describes the principal risks associated with the fund’s principal investment strategies. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.

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.

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

Investing in 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.

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

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

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

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.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

Investment results The following bar chart shows how the fund’s investment results have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compare with a broad measure of securities market results and other applicable measures of market results. This information provides some indication of the risks of investing in the fund. The Lipper Short Municipal Debt Funds Average includes the fund and other funds that disclose investment objectives and/or strategies reasonably comparable to those of the fund. The results below and on the following page for certain periods shown reflect the operation of the fund as a money market fund prior to its conversion on August 7, 2009 to a short-term tax-exempt bond fund. Accordingly, results for such periods are not representative of the fund’s results had the fund been operated as a short-term tax-exempt bond fund during the entire period. Past investment results (before and after taxes) are not predictive of future investment results. Updated information on the fund’s investment results can be obtained by visiting americanfunds.com.

After-tax returns are shown only for Class A shares; after-tax returns for other share classes will vary. After-tax returns are calculated using the highest individual federal income tax rates in effect during each year of the periods shown and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation and likely will differ from the results shown above.

Portfolio managers The individuals primarily responsible for the portfolio management of the fund are:

Purchase and sale of fund shares The minimum amount to establish an account for all share classes is $250 and the minimum to add to an account is $50. For accounts with Class F-3 shares held and serviced by the fund’s transfer agent, the minimum investment amount is $1,000,000.

If you are a retail investor, you may sell (redeem) shares on any business day through your dealer or financial advisor or by writing to American Funds Service Company^® at P.O. Box 6007, Indianapolis, Indiana 46206-6007; telephoning American Funds Service Company at (800) 421-4225; faxing American Funds Service Company at (888) 421-4351; or accessing our website at americanfunds.com.

Tax information Fund distributions of interest on municipal bonds are generally not subject to federal income tax. However, the fund may distribute taxable dividends, including distributions of short-term capital gains, which are subject to federal taxation as ordinary income. To the extent the fund is permitted to invest in bonds subject to federal alternative minimum tax, interest on certain bonds may be subject to federal alternative minimum tax. The fund’s distributions of net long-term capital gains are taxable as long-term capital gains for federal income tax purposes.

Payments to broker-dealers and other financial intermediaries If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the fund and the fund’s distributor or its affiliates may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your individual financial advisor to recommend the fund over another investment. Ask your individual financial advisor or visit your financial intermediary’s website for more information.

These risks may be increased with respect to investments in junk bonds.

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

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.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

American High-Income Municipal Bond Fund

Investment objective The fund’s investment objective is to provide you with a high level of current income exempt from regular federal income tax.

Fees and expenses of the fund This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. In addition to the fees and expenses described below, you may also be required to pay brokerage commissions on purchases and sales of Class F-2 or F-3 shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in American Funds. More information about these and other discounts is available from your financial professional, in the “Sales charge reductions and waivers” sections on page 45 of the prospectus and on page 86 of the fund’s statement of additional information, and in the sales charge waiver appendix to this prospectus.

* A contingent deferred sales charge of 1.00% applies on certain redemptions made within 18 months following purchases of $1 million or more made without an initial sales charge. Contingent deferred sales charge is calculated based on the lesser of the offering price and market value of shares being sold.

Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. You may be required to pay brokerage commissions on your purchases and sales of Class F-2 or F-3 shares of the fund, which are not reflected in the example. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 24% of the average value of its portfolio.

Principal investment strategies In seeking to achieve its objective, the fund may accept prudent risks to capital value to take advantage of opportunities for higher current income on municipal bonds. Municipal bonds are debt obligations that pay interest that is exempt from federal taxation, with payments made from a wide variety of sources, including governmental revenue streams and private enterprises.

Under normal circumstances, the fund will invest at least 80% of its assets in, or derive at least 80% of its income from, securities that are exempt from regular federal income tax and may subject you to alternative minimum tax. The fund may invest, without limitation, in securities that may subject you to federal alternative minimum tax. The fund invests at least 50% of its portfolio in debt securities rated BBB+ or below or Baa1 or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. Securities rated BB+ or below and Ba1 or below are sometimes referred to as “junk bonds.” Some of the securities in which the fund invests may have credit and liquidity support features, including guarantees and letters of credit.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers who decide how their respective segments will be invested.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is by analyzing various factors, which may include the credit strength of the issuer, prices of similar securities issued by comparable issuers, anticipated changes in interest rates, general market conditions and other factors pertinent to the particular security being evaluated. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

Principal risks This section describes the principal risks associated with the fund’s principal investment strategies. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.

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.

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

Investing in 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.

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

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

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

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

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.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

Principal investment strategies The fund seeks to achieve its objectives by primarily investing in municipal bonds issued by the state of California and its agencies and municipalities. Consistent with the fund’s objectives, the fund may also invest in municipal securities that are issued by jurisdictions outside California. Municipal bonds are debt obligations generally issued to obtain funds for various public purposes, including the construction of public facilities. The fund may also invest in bonds exempt from federal and state taxation that are used to fund private projects.

Under normal circumstances, the fund will invest at least 80% of its assets in, or derive at least 80% of its income from, securities that are exempt from both regular federal and California income taxes and that do not subject you to federal alternative minimum tax. The fund may also invest up to 20% of its assets in securities that may subject you to federal alternative minimum tax. The fund is intended primarily for taxable residents of California.

The fund will invest primarily in debt securities rated BBB- or better or Baa3 or better by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. The fund may also invest in debt securities rated BB+ or below and Ba1 or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. Such securities are sometimes referred to as “junk bonds.” Some of the securities in which the fund invests may have credit and liquidity support features, including guarantees and letters of credit.

Principal risks This section describes the principal risks associated with the fund’s principal investment strategies. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.

Risks of investing in municipal bonds of issuers within the state of California — Because the fund invests primarily in securities of issuers within the state of California, the fund is more susceptible to factors adversely affecting issuers of California securities than a comparable municipal bond mutual fund that does not concentrate its investments in a single state. For example, in the past, California voters have passed amendments to the state’s constitution and other measures that limit the taxing and spending authority of California governmental entities, and future voter initiatives may adversely affect California municipal bonds. More detailed information about the risks of investing in California municipal securities is contained in the statement of additional information.

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.

The fund’s assets are managed by a team of portfolio managers. Under this approach, the fund’s portfolio managers will work together to oversee the fund’s entire portfolio.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is by analyzing various factors, which may include the credit strength of the issuer, prices of similar securities issued by comparable issuers, anticipated changes in interest rates, general market conditions and other factors pertinent to the particular security being evaluated. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

Principal risks This section describes the principal risks associated with the fund’s principal investment strategies. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.

Risks of investing in municipal bonds of issuers within the state of New York — Because the fund invests primarily in securities of issuers within the state of New York, the fund is more susceptible to factors adversely affecting issuers of New York securities than a comparable municipal bond mutual fund that does not concentrate its investments in a single state. For example, such factors may include political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial or economic difficulties, and changes in the credit ratings assigned to New York’s municipal issuers. New York’s economy and finances may be especially vulnerable to changes in the performance of the financial services sector, which historically has been volatile. More detailed information about the risks of investing in New York municipal securities is contained in the statement of additional information.

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.

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

Investing in 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

23     Tax-exempt income funds / Prospectus

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.

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

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

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

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

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.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

Tax information Fund distributions of interest on municipal bonds are generally not subject to federal income tax. However, the fund may distribute taxable dividends, including distributions of short-term capital gains, which are subject to federal taxation as ordinary income. To the extent the fund is permitted to invest in bonds subject to federal alternative minimum tax, interest on certain bonds may be subject to federal alternative minimum tax. The fund’s distributions of net long-term capital gains are taxable as long-term capital gains for federal income tax purposes.

It is anticipated that federally exempt-interest dividends paid by the fund and derived from interest on bonds exempt from New York income tax will also be exempt from New York state and local income taxes. To the extent the fund’s dividends are derived from interest on debt obligations not exempt from New York income tax, such dividends will be subject to New York state and local income taxes. Moreover, any federally taxable dividends and capital gain distributions may also be subject to state and local taxes.

Payments to broker-dealers and other financial intermediaries If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the fund and the fund’s distributor or its affiliates may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your individual financial advisor to recommend the fund over another investment. Ask your individual financial advisor or visit your financial intermediary’s website for more information.

Municipal bonds are debt obligations generally issued to obtain funds for various public purposes, including the construction of public facilities.

A bond’s effective maturity is the market’s trading assessment of its maturity and represents an estimate of the most likely time period during which an investor in that bond will receive payment of principal. For example, as market interest rates decline, issuers may exercise call provisions that shorten the bond’s effective maturity. Conversely, if interest rates rise, effective maturities tend to lengthen. A portfolio’s dollar-weighted average effective maturity is the weighted average of all effective maturities in the portfolio, where more weight is given to larger holdings.

The fund may also hold cash or money market instruments, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund’s assets in such instruments in response to certain circumstances, such as periods of market turmoil. In addition, for temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund’s investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund’s loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The following are principal risks associated with the fund’s investment strategies.

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.

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

Investing in 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.

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

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

29     Tax-exempt income funds / Prospectus

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

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.

Risks of investing in municipal bonds of issuers within the state of California — Because the fund invests primarily in securities of issuers within the state of California, the fund is more susceptible to factors adversely affecting issuers of California securities than a comparable municipal bond mutual fund that does not concentrate its investments in a single state. For example, in the past, California voters have passed amendments to the state’s constitution and other measures that limit the taxing and spending authority of California governmental entities, and future voter initiatives may adversely affect California municipal bonds. More detailed information about the risks of investing in California municipal securities is contained in the statement of additional information.

Risks of investing in municipal bonds of issuers within the state of New York — Because the fund invests primarily in securities of issuers within the state of New York, the fund is more susceptible to factors adversely affecting issuers of New York securities than a comparable municipal bond mutual fund that does not concentrate its investments in a single state. For example, such factors may include political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial or economic difficulties, and changes in the credit ratings assigned to New York’s municipal issuers. New York’s economy and finances may be especially vulnerable to changes in the performance of the financial services sector, which historically has been volatile. More detailed information about the risks of investing in New York municipal securities is contained in the statement of additional information.

The following are certain additional risks associated with the fund’s investment strategies.

Alternative minimum tax — The fund (other than The Tax-Exempt Bond Fund of America) may invest in securities that may subject you to federal alternative minimum tax. Therefore, while the fund’s distributions from tax-exempt securities are not subject to regular federal income tax, a portion or all of the distributions may be included in determining a shareholder’s federal alternative minimum tax.

Interest rate risk — The values and liquidity of the securities held by the fund may be affected by changing interest rates. For example, the values of these securities may decline when interest rates rise and increase when interest rates fall. 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. The fund may invest in variable and floating rate securities. Although the values of such securities are generally less sensitive to interest rate changes than those of other debt securities, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Conversely, floating rate securities will not generally increase in value if interest rates decline. During periods of extremely low short-term interest rates, the fund may not be able to maintain a positive yield and, given the current historically low interest rate environment, risks associated with rising rates are currently heightened.

Exposure to country, region, industry or sector — Subject to the fund’s investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to the country, region, industry or sector than a fund without such levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund’s principal investment strategies and other investment practices. The fund’s investment results will depend on the ability of the fund’s investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

Management and organization

Investment adviser Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the fund and other funds, including the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. Capital Research and Management Company manages the investment portfolio and business affairs of the fund. The total management fee paid by the fund to its investment adviser for the most recent fiscal year, as a percentage of average net assets, appears in the Annual Fund Operating Expenses tables under “Fees and expenses of the fund.” The management fee for the fund is based on the daily net assets of the fund and the fund’s monthly gross investment income. Please see the statement of additional information for further details. A discussion regarding the basis for approval of the fund’s Investment Advisory and Service Agreements by the fund’s board of trustees is contained in the fund’s annual report to shareholders for the fiscal year ended July 31, 2018.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed-income assets through its fixed-income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital World Investors, Capital Research Global Investors and Capital International Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed-income investment division in the future and engage it to provide day-to-day investment management of fixed-income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the fund’s board, its management subsidiaries and affiliates to provide day-to-day investment management services to the fund, including making changes to the management subsidiaries and affiliates providing such services. The fund’s shareholders have approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

Portfolio holdings Portfolio holdings information for the fund is available on the American Funds website at americanfunds.com. A description of the fund’s policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

The Capital System^SM Capital Research and Management Company uses a system of multiple portfolio managers in managing mutual fund assets. Under this approach, the portfolio of a fund is divided into segments managed by individual managers who decide how their respective segments will be invested. In addition, Capital Research and Management Company’s investment analysts may make investment decisions with respect to a portion of a fund’s portfolio. Investment decisions are subject to a fund’s objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser’s fixed-income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser’s analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. The investment decisions made by the fund’s portfolio managers are informed by the investment themes discussed by the group.

The table below shows the investment experience and role in management of the fund for the fund’s primary portfolio managers. Notwithstanding The Capital System, the portfolio managers of American Funds Tax-Exempt Fund of New York will work together to oversee the fund's entire portfolio.

Shareholder information

Shareholder services American Funds Service Company, the fund’s transfer agent, offers a wide range of services that you can use to alter your investment program should your needs or circumstances change. These services may be terminated or modified at any time upon 60 days’ written notice.

A more detailed description of policies and services is included in the fund’s statement of additional information and the owner’s guide sent to new American Funds shareholders entitled Welcome. These documents are available by writing to or calling American Funds Service Company.

Unless otherwise noted, references to Class F shares refer to Class F-1, F-2, and F-3 shares.

Purchase, exchange and sale of shares The fund reserves the right not to make its shares available to tax-deferred retirement plans and accounts. The Tax-Exempt Fund of California and American Funds Tax-Exempt Fund of New York are intended primarily for taxable residents of California and New York, respectively, and may not be appropriate for residents of other states and tax-exempt entities.

The fund’s transfer agent, on behalf of the fund and American Funds Distributors,^® the fund’s distributor, is required by law to obtain certain personal information from you or any other person(s) acting on your behalf in order to verify your or such person’s identity. If you do not provide the information, the transfer agent may not be able to open your account. If the transfer agent is unable to verify your identity or that of any other person(s) authorized to act on your behalf, or believes it has identified potentially criminal activity, the fund and American Funds Distributors reserve the right to close your account or take such other action they deem reasonable or required by law.

When purchasing shares, you should designate the fund or funds in which you wish to invest. Subject to the exception below, if no fund is designated, your money will be held uninvested (without liability to the transfer agent for loss of income or appreciation pending receipt of proper instructions) until investment instructions are received, but for no more than three business days. Your investment will be made at the net asset value (plus any applicable sales charge, in the case of Class A or Class T shares) next determined after investment instructions are received and accepted by the transfer agent. If investment instructions are not received, your money will be invested in Class A shares (or, if you are investing through a financial intermediary who offers only Class T shares, in Class T shares) of American Funds U.S. Government Money Market Fund^SM on the third business day after receipt of your investment.

If the amount of your cash investment is $10,000 or less, no fund is designated, and you made a cash investment (excluding exchanges) within the last 16 months, your money will be invested in the same proportion and in the same fund or funds and in the same class of shares in which your last cash investment was made.

Different procedures may apply to certain employer-sponsored arrangements, including, but not limited to, SEPs and SIMPLE IRAs.

Valuing shares The net asset value of each share class of the fund is the value of a single share of that class. The fund calculates the net asset value each day the New York Stock Exchange is open for trading as of approximately 4 p.m. New York time, the normal close of regular trading. If, for example, the New York Stock Exchange closes at 1 p.m. New York time, the fund’s net asset value would still be determined as of 4 p.m. New York time. In this example, portfolio securities traded on the New York Stock Exchange would be valued at their closing prices unless the investment adviser determines that a “fair value” adjustment is appropriate due to subsequent events.

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services. The fund has adopted procedures for making fair value determinations if market quotations or prices from third-party pricing services, as applicable, are not readily available or are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the fund’s equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures may be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Your shares will be purchased at the net asset value (plus any applicable sales charge, in the case of Class A or Class T shares) or sold at the net asset value next determined after American Funds Service Company receives your request, provided that your request contains all information and legal documentation necessary to process the transaction. A contingent deferred sales charge may apply at the time you sell certain Class A and C shares.

Purchase of Class A, C and T shares You may generally open an account and purchase shares by contacting any financial advisor (who may impose transaction charges in addition to those described in this prospectus) authorized to sell the fund’s shares. You may purchase additional shares in various ways, including through your financial advisor and by mail, telephone, the Internet and bank wire.

Class C shares are not offered by American Funds Short-Term Tax-Exempt Bond Fund at this time. For Limited Term Tax-Exempt Bond Fund of America, Class C shares may be acquired only by exchanging from Class C shares of other American Funds. Direct purchases of Class C shares of the funds are not permitted.

Automatic conversion of Class C shares Class C shares automatically convert to Class F-1 shares in the month of the 10-year anniversary of the purchase date. The Internal Revenue Service currently takes the position that such automatic conversions are not taxable. Should its position change, the automatic conversion feature may be suspended. If this were to happen, you would have the option of converting your Class C shares to the Class F-1 shares at the anniversary date described above. This exchange would be based on the relative net asset values of the two classes in question, without the imposition of a sales charge or fee, but you might face certain tax consequences as a result.

Purchase of Class F shares You may generally open an account and purchase Class F shares only through fee-based programs of investment dealers that have special agreements with the fund’s distributor, through financial intermediaries that have been approved by, and that have special agreements with, the fund’s distributor to offer Class F shares to self-directed investment brokerage accounts that may charge a transaction fee, through certain registered investment advisors and through other intermediaries approved by the fund’s distributor. These intermediaries typically charge ongoing fees for services they provide. Intermediary fees are not paid by the fund and normally range from .75% to 1.50% of assets annually, depending on the services offered.

Class F-2 and F-3 shares may also be available on brokerage platforms of firms that have agreements with the fund’s distributor to offer such shares solely when acting as an agent for the investor. An investor transacting in Class F-2 or F-3 shares in these programs may be

Tax-exempt income funds / Prospectus     36

required to pay a commission and/or other forms of compensation to the broker. Shares of the fund are available in other share classes that have different fees and expenses.

In addition, Class F-3 shares are available to institutional investors, which include, but are not limited to, charitable organizations, governmental institutions and corporations. For accounts held and serviced by the fund’s transfer agent the minimum investment amount is $1,000,000.

Purchase minimums and maximums Purchase minimums described in this prospectus may be waived in certain cases. In addition, the fund reserves the right to redeem the shares of any shareholder for their then current net asset value per share if the shareholder’s aggregate investment in the fund falls below the fund’s minimum initial investment amount. See the statement of additional information for details.

For accounts established with an automatic investment plan, the initial purchase minimum of $250 (or $1,000 for The Tax-Exempt Fund of California and American Funds Tax-Exempt Fund of New York) may be waived if the purchases (including purchases through exchanges from another fund) made under the plan are sufficient to reach $250 (or $1,000 for The Tax-Exempt Fund of California and American Funds Tax-Exempt Fund of New York) within five months of account establishment.

The purchase maximum for Class C shares is $500,000 per transaction. In addition, if you have significant American Funds holdings, you may not be eligible to invest in Class C shares. Specifically, you may not purchase Class C shares if you are eligible to purchase Class A shares at the $1 million or more sales charge discount rate (that is, at net asset value). See “Sales charge reductions and waivers” in this prospectus and the statement of additional information for more details regarding sales charge discounts.

Exchange Except for Class T shares or as otherwise described in this prospectus, you may exchange your shares for shares of the same class of other American Funds without a sales charge. Exchanges of shares from American Funds U.S. Government Money Market Fund initially purchased without a sales charge to shares of another American Fund will be subject to the appropriate sales charge applicable to the other fund, unless American Funds U.S. Government Money Market Fund shares were acquired by an exchange from a fund having a sales charge or by reinvestment or cross-reinvestment of dividends or capital gain distributions. For purposes of computing the contingent deferred sales charge on Class C shares, the length of time you have owned your shares will be measured from the first day of the month in which shares were purchased and will not be affected by any permitted exchange.

Except as indicated above, Class T shares are not eligible for exchange privileges. Accordingly, an exchange of your Class T shares for Class T shares of any other American Fund will normally be subject to any applicable sales charges.

Exchanges have the same tax consequences as ordinary sales and purchases. For example, to the extent you exchange shares held in a taxable account that are worth more now than what you paid for them, the gain will be subject to taxation.

See “Transactions by telephone, fax or the Internet” in the section “How to sell shares” of this prospectus for information regarding electronic exchanges.

Please see the statement of additional information for details and limitations on moving investments in certain share classes to different share classes and on moving investments held in certain accounts to different accounts.

How to sell shares

You may sell (redeem) shares in any of the following ways:

Through your dealer or financial advisor (certain charges may apply)

· Shares held for you in your dealer’s name must be sold through the dealer.

·  Class F shares must be sold through intermediaries such as dealers or financial advisors.

Writing to American Funds Service Company

· Requests must be signed by the registered shareholder(s).

· A signature guarantee is required if the redemption is:

— more than $125,000;

— made payable to someone other than the registered shareholder(s); or

— sent to an address other than the address of record or to an address of record that has been changed within the previous 10 days.

· American Funds Service Company reserves the right to require signature guarantee(s) on any redemption.

· Additional documentation may be required for redemptions of shares held in corporate, partnership or fiduciary accounts.

Telephoning or faxing American Funds Service Company or using the Internet

· Redemptions by telephone, fax or the Internet (including American FundsLine and americanfunds.com) are limited to $125,000 per American Funds shareholder each day.

· Checks must be made payable to the registered shareholder.

· Checks must be mailed to an address of record that has been used with the account for at least 10 days.

The fund typically expects to pay redemption proceeds one business day following receipt and acceptance of a redemption order. However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (“1940 Act”). Under the 1940 Act, the fund may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances. In addition, if you recently purchased shares and subsequently request a redemption of those shares, the fund will pay the available redemption proceeds once a sufficient period of time has passed to reasonably ensure that

37     Tax-exempt income funds / Prospectus

checks or drafts, including certified or cashier’s checks, for the shares purchased have cleared (normally 7 business days from the purchase date).

Under normal conditions, the fund typically expects to meet shareholder redemptions by monitoring the fund’s portfolio and redemption activities and by regularly holding a reserve of highly liquid assets, such as cash or cash equivalents. The fund may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the fund’s custodian bank, borrowing from a line of credit or from other funds advised by the investment adviser or its affiliates, and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the fund’s declaration of trust permits payment of the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the fund’s board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain at market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the fund pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

Transactions by telephone, fax or the Internet Generally, you are automatically eligible to redeem or exchange shares by telephone, fax or the Internet, unless you notify us in writing that you do not want any or all of these services. You may reinstate these services at any time.

Unless you decide not to have telephone, fax or Internet services on your account(s), you agree to hold each fund, American Funds Service Company, any of its affiliates or mutual funds managed by such affiliates, and each of their respective directors, trustees, officers, employees and agents harmless from any losses, expenses, costs or liabilities (including attorney fees) that may be incurred in connection with the exercise of these privileges, provided that American Funds Service Company employs reasonable procedures to confirm that the instructions received from any person with appropriate account information are genuine. If reasonable procedures are not employed, American Funds Service Company and/or the fund may be liable for losses due to unauthorized or fraudulent instructions.

Frequent trading of fund shares The fund and American Funds Distributors reserve the right to reject any purchase order for any reason. The fund is not designed to serve as a vehicle for frequent trading. Frequent trading of fund shares may lead to increased costs to the fund and less efficient management of the fund’s portfolio, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the fund or American Funds Distributors has determined could involve actual or potential harm to the fund may be rejected.

The fund, through its transfer agent, American Funds Service Company, maintains surveillance procedures that are designed to detect frequent trading in fund shares. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company also may review transactions that occur close in time to other transactions in the same account or in multiple accounts under common ownership or influence. Trading activity that is identified through these procedures or as a result of any other information available to the fund will be evaluated to determine whether such activity might constitute frequent trading. These procedures may be modified from time to time as appropriate to improve the detection of frequent trading, to facilitate monitoring for frequent trading in particular retirement plans or other accounts and to comply with applicable laws.

In addition to the fund’s broad ability to restrict potentially harmful trading as described above, the fund’s board of trustees has adopted a “purchase blocking policy” under which any shareholder redeeming shares having a value of $5,000 or more from a fund will be precluded from investing in that fund for 30 calendar days after the redemption transaction. This policy also applies to redemptions and purchases that are part of exchange transactions. Under the fund’s purchase blocking policy, certain purchases will not be prevented and certain redemptions will not trigger a purchase block, such as:

· purchases and redemptions of shares having a value of less than $5,000;

· purchases and redemptions by investment companies managed or sponsored by the fund’s investment adviser or its affiliates, including reallocations and transactions allowing the investment company to meet its redemptions and purchases;

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper’s system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of shares of the fund, rollovers, Roth IRA conversions and IRA recharacterizations, if the entity maintaining the shareholder account is able to identify the transaction as one of these types of transactions; and

· systematic redemptions and purchases, if the entity maintaining the shareholder account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered “systematic” unless the transaction is prescheduled for a specific date.

The fund reserves the right to waive the purchase blocking policy with respect to specific shareholder accounts if American Funds Service Company determines that its surveillance procedures are adequate to detect frequent trading in fund shares in such accounts.

American Funds Service Company will work with certain intermediaries (such as investment dealers holding shareholder accounts in street name, retirement plan recordkeepers, insurance company separate accounts and bank trust companies) to apply their own procedures, provided that American Funds Service Company believes the intermediary’s procedures are reasonably designed to enforce the frequent trading policies of the fund. You should refer to disclosures provided by the intermediaries with which you have an account to determine the specific trading restrictions that apply to you.

If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the intermediary and request that the intermediary either provide information regarding an account owner’s transactions or restrict the account owner’s trading. If American Funds Service Company is not satisfied that the intermediary has taken appropriate action, American Funds Service Company may terminate the intermediary’s ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

Notwithstanding the fund’s surveillance procedures and purchase blocking policy described above, all transactions in fund shares remain subject to the right of the fund, American Funds Distributors and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented or trigger a block under the purchase blocking policy. See the statement of additional information for more information about how American Funds Service Company may address other potentially abusive trading activity in American Funds.

Distributions and taxes

Dividends and distributions The fund declares daily dividends from net investment income and distributes the accrued dividends, which may fluctuate, to you each month. Generally, dividends begin accruing on the day payment for shares is received by the fund or American Funds Service Company.

Capital gains, if any, are usually distributed in November or December. When a dividend or capital gain is distributed, the net asset value per share is reduced by the amount of the payment.

You may elect to reinvest dividends and/or capital gain distributions to purchase additional shares of this fund or other American Funds, or you may elect to receive them in cash.

Taxes on dividends and distributions Interest on municipal bonds is generally not included in gross income for federal tax purposes. Subject to certain requirements, the fund is permitted to pass through to its shareholders the interest earned on municipal bonds as federally exempt-interest dividends. Taxable dividends, including distributions of short-term capital gains, however, are subject to federal taxation at the applicable rates for ordinary income. To the extent the fund is permitted to invest in bonds subject to federal alternative minimum tax, interest earned on certain bonds may be treated as income subject to federal alternative minimum tax. The fund’s distributions of net long-term capital gains are taxable as long-term capital gains.

Depending on their state of residence, shareholders of American Funds Short-Term Tax-Exempt Bond Fund, Limited Term Tax-Exempt Bond Fund of America, The Tax-Exempt Bond Fund of America, and American High-Income Municipal Bond Fund may be able to exempt from state taxation some or all of the federally tax-exempt income dividends paid by those funds.

Each of The Tax-Exempt Fund of California and American Funds Tax-Exempt Fund of New York anticipates that the federally exempt interest dividends paid by the applicable fund and derived from interest on bonds exempt from California and New York income tax, respectively, will also be exempt from California and New York state income tax, respectively. To the extent the applicable fund’s dividends are derived from interest on debt obligations that is not exempt from California or New York income tax, however, such dividends will be subject to applicable state income tax.

Moreover, any federally taxable dividends and capital gains distributions from the fund may also be subject to state tax.

Any taxable dividends or capital gain distributions you receive from the fund normally will be taxable to you when made, regardless of whether you reinvest dividends or capital gain distributions or receive them in cash.

Taxes on transactions Your redemptions, including exchanges, may result in a capital gain or loss for federal tax purposes. A capital gain or loss on your investment is the difference between the cost of your shares, including any sales charges, and the amount you receive when you sell them.

Shareholder fees Fees borne directly by the fund normally have the effect of reducing a shareholder’s taxable income on distributions. By contrast, fees paid directly to advisors by a fund shareholder for ongoing advice are deductible for income tax purposes only to the extent that they (combined with certain other qualifying expenses) exceed 2% of such shareholder’s adjusted gross income.

Please see your tax advisor for more information.

Choosing a share class The fund offers different classes of shares through this prospectus. Shares of the fund are available through various investment programs or accounts. However, tax-exempt funds should generally not serve as investments for tax-deferred retirement plans and accounts. The services or share classes available to you may vary depending upon how you wish to purchase shares of the fund. Since shares of American Funds Short-Term Tax-Exempt Bond Fund are only available in Class A, F-1, F-2 and F-3, references to Class C shares are not applicable to American Funds Short-Term Tax-Exempt Bond Fund.

Each share class of the fund represents an investment in the same portfolio of securities, but each class has its own sales charge and expense structure, allowing you to choose the class that best fits your situation. For example, while Class F-1 shares are subject to 12b-1 fees and subtransfer agency fees payable to third-party service providers, Class F-2 shares are subject only to subtransfer agency fees payable to third-party service providers (and not 12b-1 fees) and Class F-3 shares are not subject to any such additional fees. The different fee structures allow the investor to choose how to pay for advisory platform expenses. When you purchase shares of the fund, you should choose a share class. If none is chosen, your investment will be made in Class A shares (or if you are investing through a financial intermediary who offers only Class T shares, your investment will be made in Class T shares).

Factors you should consider when choosing a class of shares include:

· how long you expect to own the shares;

· how much you intend to invest;

· total expenses associated with owning shares of each class;

· whether you qualify for any reduction or waiver of sales charges (for example, Class A or Class T shares may be a less expensive option over time, particularly if you qualify for a sales charge reduction or waiver);

·  whether you want or need the flexibility to effect exchanges among American Funds without the imposition of a sales charge (for example, while Class A shares offer such exchange privileges, Class T shares do not);

· whether you plan to take any distributions in the near future; and

· availability of share classes:

—  Class C shares are not available to retirement plans that do not currently invest in such shares and that are eligible to invest in American Funds Class R shares, including retirement plans established under Internal Revenue Code Sections 401(a) (including 401(k) plans), 403(b) or 457;

— Class F shares are available (i) to fee-based programs of investment dealers that have special agreements with the fund’s distributor, (ii) to financial intermediaries that have been approved by, and that have special agreements with, the fund’s distributor to offer Class F shares to self-directed investment brokerage accounts that may charge a transaction fee, (iii) to certain registered investment advisors and (iv) to other intermediaries approved by the fund’s distributor; and

—  Class F-3 shares are also available to institutional investors, which include, but are not limited to, charitable organizations, governmental institutions and corporations. For accounts held and serviced by the fund’s transfer agent the minimum investment amount is $1,000,000.

Each investor’s financial considerations are different. You should speak with your financial advisor to help you decide which share class is best for you.

Sales charges

Class A shares The initial sales charge you pay each time you buy Class A shares differs depending upon the amount you invest and may be reduced or eliminated for larger purchases as indicated below. The “offering price,” the price you pay to buy shares, includes any applicable sales charge, which will be deducted directly from your investment. Shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge.

Sales charges for The Tax-Exempt Bond Fund of America, American High-Income Municipal Bond Fund, The Tax-Exempt Fund of California and American Funds Tax-Exempt Fund of New York

Sales charges for American Funds Short-Term Tax-Exempt Bond Fund and Limited Term Tax-Exempt Bond Fund of America

The sales charge, expressed as a percentage of the offering price or the net amount invested, may be higher or lower than the percentages described in the tables above due to rounding. This is because the dollar amount of the sales charge is determined by subtracting the net asset value of the shares purchased from the offering price, which is calculated to two decimal places using standard rounding criteria. The impact of rounding will vary with the size of the investment and the net asset value of the shares. Similarly, any contingent deferred sales charge paid by you on investments in Class A shares may be higher or lower than the 1% charge described below due to rounding.

Except as provided below, investments in Class A shares of $1 million or more will be subject to a 1% contingent deferred sales charge if the shares are sold within 18 months of purchase. The contingent deferred sales charge is based on the original purchase cost or the current market value of the shares being sold, whichever is less. Class A shares purchased before August 14, 2017 are subject to a contingent deferred sales charge period of 12 months.

Class A share purchases not subject to sales charges The following investments are not subject to any initial or contingent deferred sales charge if American Funds Service Company is properly notified of the nature of the investment:

·  investments made by accounts that are part of qualified fee-based programs that purchased Class A shares before the discontinuation of the relevant investment dealer’s load-waived Class A share program with American Funds and that continue to be held through fee-based programs; and

· rollover investments from retirement plans to IRAs that are described in the “Rollovers from retirement plans to IRAs” section of this prospectus.

The distributor may pay dealers a commission of up to 1% on investments made in Class A shares with no initial sales charge. The fund may reimburse the distributor for these payments through its plans of distribution (see “Plans of distribution” in this prospectus).

If requested, American Funds Class A shares will be sold at net asset value to:

(1) currently registered representatives and assistants directly employed by such representatives, retired registered representatives with respect to accounts established while active, or full-time employees (collectively, “Eligible Persons”) (and their (a) spouses or equivalents if recognized under local law, (b) parents and children, including parents and children in step and adoptive relationships, sons-in-law and daughters-in-law, and (c) parents-in-law, if the Eligible Persons or the spouses, children or parents of the Eligible Persons are listed in the account registration with the parents-in-law) of dealers who have sales agreements with American Funds Distributors (or who clear transactions through such dealers), plans for the dealers, and plans that include as participants only the Eligible Persons, their spouses, parents and/or children;

(2) the supervised persons of currently registered investment advisory firms (“RIAs”) and assistants directly employed by such RIAs, retired supervised persons of RIAs with respect to accounts established while a supervised person (collectively, “Eligible Persons”) (and their (a) spouses or equivalents if recognized under local law, (b) parents and children, including parents and children in step and adoptive relationships, sons-in-law and daughters-in-law and (c) parents-in-law, if the Eligible Persons or the

Tax-exempt income funds / Prospectus     42

spouses, children or parents of the Eligible Persons are listed in the account registration with the parents-in-law) of RIA firms that are authorized to sell shares of the funds, plans for the RIA firms, and plans that include as participants only the Eligible Persons, their spouses, parents and/or children;

(4) insurance company separate accounts;

(5) accounts managed by subsidiaries of The Capital Group Companies, Inc.;

(6) an individual or entity with a substantial business relationship with The Capital Group Companies, Inc. or its affiliates, or an individual or entity related or relating to such individual or entity;

(7) wholesalers and full-time employees directly supporting wholesalers involved in the distribution of insurance company separate accounts whose underlying investments are managed by any affiliate of The Capital Group Companies, Inc.;

(8) full-time employees of banks that have sales agreements with American Funds Distributors who are solely dedicated to directly supporting the sale of mutual funds; and

(9) current or former clients of Capital Group Private Client Services and their family members who purchase their shares through Capital Group Private Client Services or American Funds Service Company.

Shares are offered at net asset value to these persons and organizations due to anticipated economies in sales effort and expense. Once an account is established under this net asset value privilege, additional investments can be made at net asset value for the life of the account. Depending on the financial intermediary holding your account, these privileges may be unavailable. Investors should consult their financial intermediary for further information.

Certain other investors may qualify to purchase shares without a sales charge, such as employees of The Capital Group Companies, Inc. and its affiliates. Please see the statement of additional information for further details.

Class C shares Class C shares are sold without any initial sales charge. American Funds Distributors pays 1% of the amount invested to dealers who sell Class C shares. A contingent deferred sales charge of 1% applies if Class C shares are sold within one year of purchase. The contingent deferred sales charge is eliminated one year after purchase.

Any contingent deferred sales charge paid by you on sales of Class C shares, expressed as a percentage of the applicable redemption amount, may be higher or lower than the percentages described above due to rounding.

Class T shares The initial sales charge you pay each time you buy Class T shares differs depending upon the amount you invest and may be reduced for larger purchases as indicated below. The “offering price,” the price you pay to buy shares, includes any applicable sales charge, which will be deducted directly from your investment. Shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge.

The sales charge, expressed as a percentage of the offering price or the net amount invested, may be higher or lower than the percentages described in the table above due to rounding. This is because the dollar amount of the sales charge is determined by subtracting the net asset value of the shares purchased from the offering price, which is calculated to two decimal places using standard rounding criteria. The impact of rounding will vary with the size of the investment and the net asset value of the shares.

Class F shares Class F shares are sold without any initial or contingent deferred sales charge.

Contingent deferred sales charges Shares acquired through reinvestment of dividends or capital gain distributions are not subject to a contingent deferred sales charge. In addition, the contingent deferred sales charge may be waived in certain circumstances. See “Contingent deferred sales charge waivers” in the “Sales charge reductions and waivers” section of this prospectus. For purposes of determining the contingent deferred sales charge, if you sell only some of your shares, shares that are not subject to any contingent deferred sales charge will be sold first, followed by shares that you have owned the longest.

Sales charge reductions and waivers To receive a reduction in your Class A initial sales charge, you must let your financial advisor or American Funds Service Company know at the time you purchase shares that you qualify for such a reduction. If you do not let your advisor or American Funds Service Company know that you are eligible for a reduction, you may not receive the sales charge discount to which you are otherwise entitled. In order to determine your eligibility to receive a sales charge discount, it may be necessary for you to provide your advisor or American Funds Service Company with information and records (including account statements) of all relevant accounts invested in American Funds. You may need to invest directly through American Funds Service Company in order to receive the sales charge waivers described in this prospectus. Investors should consult their financial intermediary for further information. Certain financial intermediaries that distribute shares of American Funds may impose different sales charge waivers than those described in this prospectus. Such variations in sales charge waivers are described in an appendix to this prospectus titled “Sales charge waivers.” Note that such sales charge waivers and discounts offered through a particular intermediary, as set forth in the appendix to this prospectus, are implemented and administered solely by that intermediary. Please contact the applicable intermediary to ensure that you understand the steps you must take in order to qualify for any available waivers or discounts.

In addition to the information in this prospectus, you may obtain more information about share classes, sales charges and sales charge reductions and waivers through a link on the home page of the American Funds website at americanfunds.com, from the statement of additional information or from your financial advisor.

Reducing your Class A initial sales charge Consistent with the policies described in this prospectus, you and your “immediate family” (your spouse — or equivalent, if recognized under local law, your children under the age of 21 or disabled adult dependents covered by ABLE accounts) may combine all of your American Funds investments to reduce Class A sales charges. However, for this purpose, investments representing direct purchases of American Funds U.S. Government Money Market Fund are excluded. Following are different ways that you may qualify for a reduced Class A sales charge:

Aggregating accounts To receive a reduced Class A sales charge, investments made by you and your immediate family (see above) may be aggregated if made for your own account(s) and/or certain other accounts, such as:

· individual-type employee benefit plans, such as an IRA, single-participant Keogh-type plan, or a participant account of a 403(b) plan that is treated as an individual-type plan for sales charge purposes (see “Purchases by certain 403(b) plans” under “Rollovers from retirement plans to IRAs” below);

· SEP plans and SIMPLE IRA plans established after November 15, 2004, by an employer adopting any plan document other than a prototype plan produced by American Funds Distributors;

· business accounts solely controlled by you or your immediate family (for example, you own the entire business);

· trust accounts established by you or your immediate family (for trusts with only one primary beneficiary, upon the trustor’s death the trust account may be aggregated with such beneficiary’s own accounts; for trusts with multiple primary beneficiaries, upon the trustor’s death the trustees of the trust may instruct American Funds Service Company to establish separate trust accounts for each primary beneficiary; each primary beneficiary’s separate trust account may then be aggregated with such beneficiary’s own accounts);

· endowments or foundations established and controlled by you or your immediate family; or

· 529 accounts, which will be aggregated at the account owner level (Class 529-E accounts may only be aggregated with an eligible employer plan).

Individual purchases by a trustee(s) or other fiduciary(ies) may also be aggregated if the investments are:

· for a single trust estate or fiduciary account, including employee benefit plans other than the individual-type employee benefit plans described above;

· made for two or more employee benefit plans of a single employer or of affiliated employers as defined in the 1940 Act, excluding the individual-type employee benefit plans described above;

· for a diversified common trust fund or other diversified pooled account not specifically formed for the purpose of accumulating fund shares;

· for nonprofit, charitable or educational organizations, or any endowments or foundations established and controlled by such organizations, or any employer-sponsored retirement plans established for the benefit of the employees of such organizations, their endowments, or their foundations;

· for participant accounts of a 403(b) plan that is treated as an employer-sponsored plan for sales charge purposes (see “Purchases by certain 403(b) plans” under “Rollovers from retirement plans to IRAs” below), or made for participant accounts of two or more such plans, in each case of a single employer or affiliated employers as defined in the 1940 Act; or

· for a SEP or SIMPLE IRA plan established after November 15, 2004, by an employer adopting a prototype plan produced by American Funds Distributors.

Purchases made for nominee or street name accounts (securities held in the name of an investment dealer or another nominee such as a bank trust department instead of the customer) may not be aggregated with those made for other accounts and may not be aggregated with other nominee or street name accounts unless otherwise qualified as described above.

Joint accounts may be aggregated with other accounts belonging to the primary owner and/or his or her immediate family. The primary owner of a joint account is the individual responsible for taxes on the account.

Concurrent purchases You may reduce your Class A sales charge by combining simultaneous purchases (including, upon your request, purchases for gifts) of all classes of shares in American Funds. Shares of American Funds U.S. Government Money Market Fund purchased through an exchange, reinvestment or cross-reinvestment from a fund having a sales charge also qualify. However, direct

45     Tax-exempt income funds / Prospectus

purchases of American Funds U.S. Government Money Market Fund are excluded. If you currently have individual holdings in American Legacy variable annuity contracts or variable life insurance policies that were established on or before March 31, 2007, you may continue to combine purchases made under such contracts and policies to reduce your Class A sales charge.

Rights of accumulation Subject to the limitations described in the aggregation policy, you may take into account your accumulated holdings in all share classes of American Funds to determine your sales charge on investments in accounts eligible to be aggregated. Direct purchases of American Funds U.S. Government Money Market Fund are excluded. Subject to your investment dealer’s or recordkeeper’s capabilities, your accumulated holdings will be calculated as the higher of (a) the current value of your existing holdings (the “market value”) as of the day prior to your American Funds investment or (b) the amount you invested (including reinvested dividends and capital gains, but excluding capital appreciation) less any withdrawals (the “cost value”). Depending on the entity on whose books your account is held, the value of your holdings in that account may not be eligible for calculation at cost value. For example, accounts held in nominee or street name may not be eligible for calculation at cost value and instead may be calculated at market value for purposes of rights of accumulation.

The value of all of your holdings in accounts established in calendar year 2005 or earlier will be assigned an initial cost value equal to the market value of those holdings as of the last business day of 2005. Thereafter, the cost value of such accounts will increase or decrease according to actual investments or withdrawals. You must contact your financial advisor or American Funds Service Company if you have additional information that is relevant to the calculation of the value of your holdings.

When determining your American Funds Class A sales charge, if your investment is not in an employer-sponsored retirement plan, you may also continue to take into account the market value (as of the day prior to your American Funds investment) of your individual holdings in various American Legacy variable annuity contracts and variable life insurance policies that were established on or before March 31, 2007. An employer-sponsored retirement plan may also continue to take into account the market value of its investments in American Legacy Retirement Investment Plans that were established on or before March 31, 2007.

You may not purchase Class C shares of American High-Income Municipal Bond Fund or American Funds Tax-Exempt Fund of New York if such combined American Funds and American Funds Legacy holdings cause you to be eligible to purchase Class A shares at the $1 million or more sales charge discount rate (i.e., at net asset value).

If you make a gift of American Funds Class A shares, upon your request, you may purchase the shares at the sales charge discount allowed under rights of accumulation of all of your American Funds and applicable American Legacy accounts.

You should retain any records necessary to substantiate the historical amounts you have invested.

Statement of intention You may reduce your Class A sales charge by establishing a statement of intention. A statement of intention is a nonbinding commitment that allows you to combine all purchases of all American Funds share classes (excluding American Funds U.S. Government Money Market Fund) that you intend to make over a 13-month period to determine the applicable sales charge; however, purchases made under a right of reinvestment, appreciation of your holdings, and reinvested dividends and capital gains do not count as purchases made during the statement period. Your accumulated holdings (as described and calculated under “Rights of accumulation” above) eligible to be aggregated as of the day immediately before the start of the statement period may be credited toward satisfying the statement. A portion of your account may be held in escrow to cover additional Class A sales charges that may be due if your total purchases over the statement period do not qualify you for the applicable sales charge reduction.

The statement of intention period starts on the date on which your first purchase made toward satisfying the statement of intention is processed. Your accumulated holdings (as described above under “Rights of accumulation”) eligible to be aggregated as of the day immediately before the start of the statement of intention period may be credited toward satisfying the statement of intention.

You may revise the commitment you have made in your statement of intention upward at any time during the statement of intention period. If your prior commitment has not been met by the time of the revision, the statement of intention period during which purchases must be made will remain unchanged. Purchases made from the date of the revision will receive the reduced sales charge, if any, resulting from the revised statement of intention. If your prior commitment has been met by the time of the revision, your original statement of intention will be considered met and a new statement of intention will be established.

The statement of intention will be considered completed if the shareholder dies within the 13-month statement of intention period. Commissions to dealers will not be adjusted or paid on the difference between the statement of intention amount and the amount actually invested before the shareholder’s death.

When a shareholder elects to use a statement of intention, shares equal to 5% of the dollar amount specified in the statement of intention may be held in escrow in the shareholder’s account out of the initial purchase (or subsequent purchases, if necessary) by American Funds Service Company. All dividends and any capital gain distributions on shares held in escrow will be credited to the shareholder’s account in shares (or paid in cash, if requested). If the intended investment is not completed within the specified statement of intention period the investments made during the statement period will be adjusted to reflect the difference between the sales charge actually paid and the sales charge which would have been paid if the total of such purchases had been made at a single time. Any dealers assigned to the shareholder’s account at the time a purchase was made during the statement period will receive a corresponding commission adjustment if appropriate.

In addition, if you currently have individual holdings in American Legacy variable annuity contracts or variable life insurance policies that were established on or before March 31, 2007, you may continue to apply purchases under such contracts and policies to a statement of intention.

Tax-exempt income funds / Prospectus     46

Shareholders purchasing shares at a reduced sales charge under a statement of intention indicate their acceptance of these terms and those in the prospectus with their first purchase.

Reducing your Class T initial sales charge Consistent with the policies described in this prospectus, the initial sales charge you pay each time you buy Class T shares may differ depending upon the amount you invest and may be reduced for larger purchases. Additionally, Class T shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge. Sales charges on Class T shares are applied on a transaction-by-transaction basis, and, accordingly, Class T shares are not eligible for any other sales charge waivers or reductions, including through the aggregation of Class T shares concurrently purchased by other related accounts or in other American Funds. The sales charge applicable to Class T shares may not be reduced by establishing a statement of intention, and rights of accumulation are not available for Class T shares.

Right of reinvestment If you notify American Funds Service Company prior to the time of reinvestment, you may reinvest proceeds from a redemption, dividend payment or capital gain distribution without a sales charge in the same fund or other American Funds, provided that the reinvestment occurs within 90 days after the date of the redemption, dividend payment or distribution and is made into the same account from which you redeemed the shares or received the dividend payment or distribution. If the account has been closed, you may reinvest without a sales charge if the new receiving account has the same registration as the closed account and the reinvestment is made within 90 days after the date of redemption, dividend payment or distribution.

Proceeds from a redemption and all dividend payments and capital gain distributions will be reinvested in the same share class from which the original redemption, dividend payment or distribution was made. Any contingent deferred sales charge on Class A or C shares will be credited to your account. Redemption proceeds of Class A shares representing direct purchases in American Funds U.S. Government Money Market Fund that are reinvested in other American Funds will be subject to a sales charge.

Proceeds will be reinvested at the next calculated net asset value after your request is received by American Funds Service Company, provided that your request contains all information and legal documentation necessary to process the transaction. For purposes of this “right of reinvestment policy,” automatic transactions (including, for example, automatic purchases, withdrawals and payroll deductions) and ongoing retirement plan contributions are not eligible for investment without a sales charge. You may not reinvest proceeds in American Funds as described in this paragraph if such proceeds are subject to a purchase block as described under “Frequent trading of fund shares” in this prospectus. This paragraph does not apply to certain rollover investments as described under “Rollovers from retirement plans to IRAs” in this prospectus. Depending on the financial intermediary holding your account, your reinvestment privileges may be unavailable or differ from those described in this prospectus. Investors should consult their financial intermediary for further information.

Contingent deferred sales charge waivers The contingent deferred sales charge on Class A and C shares will be waived in the following cases:

· permitted exchanges of shares, except if shares acquired by exchange are then redeemed within the period during which a contingent deferred sales charge would apply to the initial shares purchased;

· tax-free returns of excess contributions to IRAs;

· redemptions due to death or postpurchase disability of the shareholder (this generally excludes accounts registered in the names of trusts and other entities);

· in the case of joint tenant accounts, if one joint tenant dies, a surviving joint tenant, at the time he or she notifies American Funds Service Company of the other joint tenant’s death and removes the decedent’s name from the account, may redeem shares from the account without incurring a contingent deferred sales charge; however, redemptions made after American Funds Service Company is notified of the death of a joint tenant will be subject to a contingent deferred sales charge;

· redemptions due to the complete termination of a trust upon the death of the trustor/grantor or beneficiary, but only if such termination is specifically provided for in the trust document; and

· the following types of transactions, if they do not exceed 12% of the value of an account annually:

— required minimum distributions taken from retirement accounts upon the shareholder’s attainment of age 70½ (required minimum distributions that continue to be taken by the beneficiary(ies) after the account owner is deceased also qualify for a waiver); and

— redemptions through an automatic withdrawal plan (“AWP”) (see “Automatic withdrawals” under “Shareholder account services and privileges” in the statement of additional information). For each AWP payment, assets that are not subject to a contingent deferred sales charge, such as shares acquired through reinvestment of dividends and/or capital gain distributions, will be redeemed first and will count toward the 12% limit. If there is an insufficient amount of assets not subject to a contingent deferred sales charge to cover a particular AWP payment, shares subject to the lowest contingent deferred sales charge will be redeemed next until the 12% limit is reached. Any dividends and/or capital gain distributions taken in cash by a shareholder who receives payments through an AWP will also count toward the 12% limit. In the case of an AWP, the 12% limit is calculated at the time an automatic redemption is first made, and is recalculated at the time each additional automatic redemption is made. Shareholders who establish an AWP should be aware that the amount of a payment not subject to a contingent deferred sales charge may vary over time depending on fluctuations in the value of their accounts. This privilege may be revised or terminated at any time.

For purposes of this paragraph, “account” means your investment in the applicable class of shares of the particular fund from which you are making the redemption.

The contingent deferred sales charge on American Funds Class A shares may be waived in cases where the fund’s transfer agent determines the benefit to the fund of collecting the contingent deferred sales charge would be outweighed by the cost of applying it.

Contingent deferred sales charge waivers are allowed only in the cases listed here and in the statement of additional information.

To have your Class A or C contingent deferred sales charge waived, you must inform your advisor or American Funds Service Company at the time you redeem shares that you qualify for such a waiver.

Rollovers from retirement plans to IRAs The fund reserves the right not to make its shares available to tax-deferred retirement plans and accounts.

Assets from retirement plans may be invested in Class A, C or F shares through an IRA rollover, subject to the other provisions of this prospectus. Class C shares are not available if the assets are being rolled over from investments held in American Funds Recordkeeper Direct and PlanPremier retirement plan recordkeeping programs.

Rollovers to IRAs from retirement plans that are rolled into Class A shares will be subject to applicable sales charges. The following rollovers to Class A shares will be made without a sales charge:

· rollovers to Capital Bank and Trust Company^SM IRAs if the assets were invested in American Funds at the time of distribution;

· rollovers to IRAs from 403(b) plans with Capital Bank and Trust Company as custodian; and

·  rollovers to Capital Bank and Trust Company IRAs from investments held in American Funds Recordkeeper Direct and PlanPremier retirement plan recordkeeping programs.

IRA rollover assets that roll over without a sales charge as described above will not be subject to a contingent deferred sales charge, and investment dealers will be compensated solely with an annual service fee that begins to accrue immediately. All other rollovers invested in Class A shares, as well as future contributions to the IRA, will be subject to sales charges and to the terms and conditions generally applicable to Class A share investments as described in this prospectus and in the statement of additional information.

Tax-exempt income funds / Prospectus     48

Other sales charge waivers Waivers of all or a portion of the contingent deferred sales charge on Class C shares will be granted for transactions requested by financial intermediaries as a result of (i) pending or anticipated regulatory matters that require investor accounts to be moved to a different share class or (ii) conversions of IRAs from brokerage to advisory accounts in cases where new investments in brokerage IRA accounts have been restricted by the intermediary.

Purchases by SEP plans and SIMPLE IRA plans Participant accounts in a Simplified Employee Pension (SEP) plan or a Savings Incentive Match Plan for Employees of Small Employers IRA (SIMPLE IRA) will be aggregated at the plan level for Class A sales charge purposes if an employer adopts a prototype plan produced by American Funds Distributors or (a) the employer or plan sponsor submits all contributions for all participating employees in a single contribution transmittal or the contributions are identified as related to the same plan; (b) each transmittal is accompanied by checks or wire transfers and generally must be submitted through the transfer agent’s automated contribution system if held on the fund’s books; and (c) if the fund is expected to carry separate accounts in the name of each plan participant and (i) the employer or plan sponsor notifies the funds’ transfer agent or the intermediary holding the account that the separate accounts of all plan participants should be linked and (ii) all new participant accounts are established by submitting the appropriate documentation on behalf of each new participant. Participant accounts in a SEP or SIMPLE plan that are eligible to aggregate their assets at the plan level may not also aggregate the assets with their individual accounts.

Purchases by certain 403(b) plans Tax-exempt funds in general should not serve as retirement plan investments.

A 403(b) plan may not invest in American Funds Class A or C shares unless such plan was invested in Class A or C shares before January 1, 2009.

Participant accounts of a 403(b) plan that invested in American Funds Class A or C shares and were treated as an individual-type plan for sales charge purposes before January 1, 2009, may continue to be treated as accounts of an individual-type plan for sales charge purposes. Participant accounts of a 403(b) plan that invested in American Funds Class A or C shares and were treated as an employer-sponsored plan for sales charge purposes before January 1, 2009, may continue to be treated as accounts of an employer-sponsored plan for sales charge purposes. Participant accounts of a 403(b) plan that was established on or after January 1, 2009, are treated as accounts of an employer-sponsored plan for sales charge purposes.

Moving between accounts American Funds investments by certain account types may be moved to other account types without incurring additional Class A sales charges. These transactions include:

·   redemption proceeds from a non-retirement account (for example, a joint tenant account) used to purchase fund shares in an IRA or other individual-type retirement account;

·   required minimum distributions from an IRA or other individual-type retirement account used to purchase fund shares in a non-retirement account; and

·   death distributions paid to a beneficiary’s account that are used by the beneficiary to purchase fund shares in a different account.

These privileges are generally available only if your account is held directly with the fund’s transfer agent or if the financial intermediary holding your account has the systems, policies and procedures to support providing the privileges on its systems. Investors should consult their financial intermediary for further information.

49     Tax-exempt income funds / Prospectus

Plans of distribution The fund has plans of distribution, or “12b-1 plans,” for certain share classes under which it may finance activities intended primarily to sell shares, provided that the categories of expenses are approved in advance by the fund's board of trustees. The plans provide for payments, based on annualized percentages of average daily net assets, of:

For all share classes indicated above, up to .25% (.15% for Class A shares of American Funds Short-Term Tax-Exempt Bond Fund) may be used to pay service fees to qualified dealers for providing certain shareholder services. The amount remaining for each share class, if any, may be used for distribution expenses.

The 12b-1 fees paid by each applicable share class of each fund, as a percentage of average net assets for the most recent fiscal year, are indicated in the prospectus in the Annual Fund Operating Expenses table for each fund. Since these fees are paid out of each fund’s assets on an ongoing basis, over time they may cost you more than paying other types of sales charges or service fees and reduce the return on your investment. The higher fees for Class C shares may cost you more over time than paying the initial sales charge for Class A or T shares.

Other compensation to dealers American Funds Distributors, at its expense, provides additional compensation to investment dealers. These payments may be made, at the discretion of American Funds Distributors, to the top 100 dealers (or their affiliates) that have sold shares of American Funds. A number of factors will be considered in determining payments, including the qualifying dealer’s sales, assets and positive cash flows, and the quality of the dealer’s relationship with American Funds Distributors. The payment will be determined using a formula applied consistently to dealers based on the relevant facts and circumstances. The level of payments made to a qualifying firm in any given year will vary and (excluding payments for meetings as described below) will represent the sum of (a) up to .10% of the previous year’s American Funds sales by that dealer and (b) up to .02% of American Funds assets attributable to that dealer, with an adjustment made for the dealer’s positive cash flows and the quality of the dealer’s relationship with American Funds Distributors. Retirement plan assets are generally excluded from the formula. Certain investment dealers may direct American Funds Distributors to exclude additional assets. For calendar year 2017, aggregate payments made by American Funds Distributors to dealers were less than .02% of American Funds’ average assets. Aggregate payments made by American Funds Distributors to dealers may also change from year to year. American Funds Distributors makes these payments to help defray the costs incurred by qualifying dealers in connection with efforts to educate financial advisors about American Funds so that they can make recommendations and provide services that are suitable and meet shareholder needs. These payments may also be made to help defray the costs associated with the dealer firms’ provision of account related services and activities. American Funds Distributors will, on an annual basis, determine the advisability of continuing these payments.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and American Funds Distributors’ goal that the payment will help facilitate education of the firm’s financial advisors about American Funds to help the advisors make suitable recommendations and better serve their clients who invest in the funds. The letters generally require the firms to (1) have significant assets invested in American Funds, (2) perform the due diligence necessary to classify American Funds as “approved” or “preferred” (or an equivalent) on their platform, (3) not provide financial advisors, branch managers or associated persons with any financial incentives to promote the sales of one approved fund group over another approved group, (4) provide opportunities for their clients to obtain individualized advice, (5) provide American Funds Distributors broad access to their financial advisors and product platforms and develop a business plan to achieve such access, and (6) work with the fund’s transfer agent to promote operational efficiencies and to facilitate necessary communication between American Funds and the firm’s clients who own shares of American Funds.

American Funds Distributors may also pay expenses associated with meetings and other training and educational opportunities conducted by selling dealers, advisory platform providers and other intermediaries to facilitate educating financial advisors and shareholders about American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, and fees to obtain lists of financial advisors to better tailor training and education opportunities.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to investment dealers in differing amounts, dealer firms and their advisors may have financial incentives for recommending a particular mutual fund over other mutual funds or investments. You should consult with your financial advisor and review carefully any disclosure by your financial advisor’s firm as to compensation received.

Fund expenses In periods of market volatility, assets of the fund may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

For all share classes, “Other expenses” items in the Annual Fund Operating Expenses tables in this prospectus include fees for administrative services provided by the fund’s investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders. The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of 0.05% for all share classes. The fund’s investment adviser currently receives an administrative services fee at the annual rate of .01% of the average daily net assets of the fund attributable to Class A shares (which could be increased as noted above) and .05% of the average daily net assets of the fund attributable to Class C, T and F shares for its provision of administrative services.

The “Other expenses” items in the Annual Fund Operating Expenses table also include custodial, legal and transfer agent (and, if applicable, subtransfer agent/recordkeeping) payments and various other expenses applicable to all share classes.

Subtransfer agent/recordkeeping payments may be made to third parties (including affiliates of the fund’s investment adviser) that provide subtransfer agent, recordkeeping and/or shareholder services with respect to certain shareholder accounts in lieu of the transfer agent providing such services. The amount paid for subtransfer agent/recordkeeping services varies depending on the share class and services provided, and typically ranges from $3 to $18 per account. Although Class F-3 shares are not subject to any subtransfer agency or recordkeeping fees, Class F-1 and F-2 shares are subject to subtransfer agency fees of up to .12% of fund assets.

Financial highlights The Financial Highlights tables are intended to help you understand the fund’s results for the past five fiscal years. Certain information reflects financial results for a single share of a particular class. The total returns in the tables represent the rate that an investor would have earned or lost on an investment in the fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the tables reflect the impact, if any, of certain reimbursements from Capital Research and Management Company. For more information about these reimbursements, see the fund’s statement of additional information and annual reports. The information in the Financial Highlights tables for American Funds Short-Term Tax-Exempt Bond Fund, Limited Term Tax-Exempt Bond Fund of America, The Tax-Exempt Bond Fund of America, American High-Income Municipal Bond Fund, The Tax-Exempt Fund of California and American Funds Tax-Exempt Fund of New York has been audited by PricewaterhouseCoopers LLP.
