The fund may also invest in common stocks, or securities convertible into common stocks, of issuers outside the U.S. with the potential to pay dividends in the future. Under normal market conditions, the fund will invest at least 80% of its net assets in equity-type securities and at least 80% of its net assets in securities of issuers outside the United States. The fund may invest up to 15% of its net assets in the securities of issuers based in emerging markets. In pursuing the fund's objectives, the investment adviser will seek to preserve your investment. While the investment adviser seeks to preserve capital, investing is subject to market risks and may result in periods of volatility and the potential for loss. In pursuing the fund's growth objective, the fund's investment adviser focuses primarily on companies with attributes that are associated with long-term growth, such as strong management, participation in a growing market and the potential for above average growth in earnings, revenues, book value, cash flow and/or return on assets. The investment adviser also invests in companies with the potential to provide income in pursuing the fund's objectives. 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 valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.
Risk [Heading]	rr_RiskHeading	Principal risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. Market conditions - The prices of, and the income generated by, the securities held by the fund may decline due to market conditions and other factors, including those directly involving the issuers of securities held by the fund. Investing in growth-oriented stocks - Growth-oriented stocks may involve larger price swings and greater potential for loss than other types of investments. Investing outside the United States - Securities of issuers domiciled outside the United States, or with significant operations outside the United States, may lose value because of adverse political, social, economic or market developments in the countries or regions in which the issuer operates. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different settlement and accounting practices and different regulatory, legal and reporting standards, and may be more difficult to value, than those in the United States. The risks of investing outside the United States may be heightened in connection with investments in emerging markets. Management - The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the investment adviser in this process may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives. 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.

[1] Clients of Capital Guardian Trust Company's Capital Group Private Client Services division ("CGPCS") are eligible to invest in the fund.

[2] The fund's investment adviser is currently reimbursing the fund for a portion of other expenses so that total fund expenses do not exceed .85%.

The fund invests primarily in common stocks, or securities convertible into
common stocks, of issuers around the world that the investment adviser believes
have the potential for growth. The fund may also invest in common stocks, or
securities convertible into common stocks, of issuers around the world with the
potential to pay dividends in the future. Under normal market conditions, the
fund will invest at least 80% of its net assets in equity-type securities. The
fund will allocate its assets among various countries, including the United
States (but in no fewer than three countries). Under normal market conditions,
the fund will invest significantly in issuers outside the United States (at
least 40% of its net assets - unless market conditions are not deemed favorable
by the fund's investment adviser, in which case the fund would invest at least
30% of its net assets). The fund may invest up to 10% of its net assets in the
securities of issuers based in emerging markets.

Capital U.S. Equity Fund (Prospectus Summary) | Capital U.S. Equity Fund

Capital U.S. Equity FundSM

Investment objectives

The fund seeks to preserve your investment while providing growth.

The fund's secondary objective is to provide you with income.

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.

Shareholder fees (fees paid directly from your investment)

Shareholder Fees	Capital U.S. Equity Fund Share class
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of the amount redeemed)	none
Maximum sales charge (load) imposed on reinvested dividends	none
Redemption or exchange fees	none

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Capital U.S. Equity Fund Share class
Management fees		0.65%
Distribution and/or service (12b-1) fees		none
Other expenses	[1]	0.02%
Total annual fund operating expenses		0.67%
Expense reimbursement	[2]	0.02%
Total annual fund operating expenses after reimbursement		0.65%

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.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Capital U.S. Equity Fund Share class	66	212	371	833

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 53% of the average value of its portfolio.

Principal investment strategies

The fund invests primarily in common stocks, or securities convertible into
common stocks, of U.S. issuers that the investment adviser believes have the
potential for growth. The fund may also invest in common stocks, or securities
convertible into common stocks, of U.S. issuers with the potential to pay
dividends in the future. Under normal market conditions, the fund will invest at
least 80% of its net assets in equity-type securities and at least 80% of its
net assets in securities of issuers in the United States. Investments may
include U.S. registered securities of issuers outside of the United States such
as American Depository Receipts.

In pursuing the fund's objectives, the investment adviser will seek to preserve
your investment. While the investment adviser seeks to preserve capital,
investing is subject to market risks and may result in periods of volatility and
the potential for loss. In pursuing the fund's growth objective, the fund's
investment adviser focuses primarily on companies with attributes that are
associated with long-term growth, such as strong management, participation in a
growing market and the potential for above average growth in earnings, revenues,
book value, cash flow and/or return on assets. The investment adviser also
invests in companies with the potential to provide income in pursuing the fund's
objectives.

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 valued companies
that, in its opinion, represent good, long-term investment opportunities. The
investment adviser believes that an important way to accomplish this is through
fundamental analysis, which may include meeting with company executives and
employees, suppliers, customers and competitors. 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.
Investors in the fund should have a long-term perspective and be able to
tolerate potentially sharp declines in value.

Market conditions - The prices of, and the income generated by, the securities
held by the fund may decline due to market conditions and other factors,
including those directly involving the issuers of securities held by the fund.

Investing in growth-oriented stocks - Growth-oriented stocks may involve larger
price swings and greater potential for loss than other types of investments.

Investing in income-oriented stocks - Income provided by the fund may be reduced
by changes in the dividend policies of, and the capital resources available at,
the companies in which the fund invests.

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

Information regarding investment results is not available as of the date of this
prospectus because the fund's 2012 results were not available on January 1, 2013.

CGPCS receives an annual service fee of up to .75% of a client's investment in the fund under management by CGPCS pursuant to an investment management agreement. You should read carefully the disclosures provided to you by CGPCS regarding the fees. The disclosures include information about the fees charged to you and paid to CGPCS for the services it provides.

[2] The fund's investment adviser is currently reimbursing the fund for a portion of other expenses so that total fund expenses do not exceed .65%.

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.

Capital Short-Term Municipal Fund Share class	41	142	252	573

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 25% of the average value of its portfolio.

Principal investment strategies

The fund seeks to achieve its objective by investing primarily in short-term
municipal bonds.

The fund will invest at least 80% of its assets in bonds (for purposes of this
limit, bonds include any debt instrument and cash equivalents, and may include
certain preferred securities). 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 federal income tax. The fund will not invest in
securities that subject you to the federal alternative minimum tax. The
investment adviser will seek to manage the fund in order to minimize capital
gain distributions.

The fund invests primarily in municipal bonds with quality ratings of AA- or
better or Aa3 or better by Nationally Recognized Statistical Ratings Organizations
("NRSROs") 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 municipal bonds in the rating categories of A- or A3 by NRSROs or
unrated but determined by the fund's investment adviser to be of equivalent
quality. Under normal circumstances, the fund's aggregate portfolio will have a
dollar-weighted average 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 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 due to market conditions and other factors,
including those directly involving the issuers of securities held by the fund.

Investing in bonds - Rising interest rates will generally cause the prices of
bonds and other debt securities to fall. Longer maturity debt securities may be
subject to greater price fluctuations than shorter maturity debt securities. In
addition, falling interest rates may cause an issuer to redeem, call or refinance
a security before its stated maturity, which may result in the fund having to
reinvest the proceeds in lower yielding securities.

Bonds and other debt securities are subject to credit risk, which is the
possibility that the credit strength of an issuer will weaken and/or an issuer
of a debt security will fail to make timely payments of principal or interest
and the security will go into default. Credit risk is gauged, in part, by the
credit ratings of the 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.

Credit and liquidity support - Changes in the credit quality of banks and
financial institutions providing credit and liquidity support features could
cause the fund to experience a loss and may affect its share price.

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

Investing in similar municipal bonds - Investing significantly in municipal
obligations of issuers in the same state or backed by revenues of similar types
of projects or industries may make 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.

shares through a tax-favored arrangement, such as a 401(k) plan or individual
retirement account (IRA).

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. 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 due to market conditions and other factors, including those directly involving the issuers of securities held by the fund. Investing in bonds - Rising interest rates will generally cause the prices of bonds and other debt securities to fall.

Capital Core Bond Fund (Prospectus Summary) | Capital Core Bond Fund

Capital Core Bond FundSM

Investment objective

The fund's investment objective is to provide you with current income while
preserving your investment.

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.

Shareholder fees (fees paid directly from your investment)

Shareholder Fees	Capital Core Bond Fund Share class
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of the amount redeemed)	none
Maximum sales charge (load) imposed on reinvested dividends	none
Redemption or exchange fees	none

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Capital Core Bond Fund Share class
Management fees		0.35%
Distribution and/or service (12b-1) fees		none
Other expenses	[1]	0.07%
Total annual fund operating expenses		0.42%
Expense reimbursement	[2]	0.02%
Total annual fund operating expenses after reimbursement		0.40%

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.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Capital Core Bond Fund Share class	41	133	233	528

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 134% of the average value of its portfolio.

Principal investment strategies

The fund primarily invests in intermediate-term debt securities, including
securities issued and guaranteed by the U.S. government and securities backed
by mortgages or other assets. The fund may also invest in debt securities and
mortgage-backed securities issued by federal agencies and instrumentalities that
are not backed by the full faith and credit of the U.S. government. In addition,
the fund may invest in asset-backed securities (securities backed by assets such
as auto loans, credit card receivables or other providers of credit).

The fund will invest at least 80% of its assets in bonds (for purposes of this
limit, bonds include any debt instrument and cash equivalents, and may include
certain preferred securities). The fund primarily invests in debt securities
with quality ratings of A- or A3 or better by Nationally Recognized Statistical
Ratings Organizations ("NRSROs") designated by the fund's investment adviser or
unrated but determined to be of equivalent quality by the fund's investment
adviser. The fund may invest up to 10% of its assets in debt securities rated in
the BBB or Baa rating categories by NRSROs or unrated but determined to be of
equivalent quality by the fund's investment adviser. Under normal circumstances,
the dollar-weighted average maturity of the fund's portfolio will be between
three and 10 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 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 due to market conditions and other factors,
including those directly involving the issuers of securities held by the fund.

Investing in bonds - Rising interest rates will generally cause the prices of
bonds and other debt securities to fall. Longer maturity debt securities may be
subject to greater price fluctuations than shorter maturity debt securities. In
addition, falling interest rates may cause an issuer to redeem, call or refinance
a security before its stated maturity, which may result in the fund having to
reinvest the proceeds in lower yielding securities.

Bonds and other debt securities are subject to credit risk, which is the
possibility that the credit strength of an issuer will weaken and/or an issuer
of a debt security will fail to make timely payments of principal or interest
and the security will go into default. Credit risk is gauged, in part, by the
credit ratings of the 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.

Investing in lower rated bonds - 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.

Investing in mortgage-related securities - Many types of bonds and other debt
securities, including mortgage-backed securities, are subject to prepayment risk
as well as the risks associated with investing in debt securities in general. If
interest rates fall and the loans underlying these securities are prepaid faster
than expected, the fund may have to reinvest the prepaid principal in lower
yielding securities, thus reducing the fund's income. Conversely, if interest
rates increase and the loans underlying the securities are prepaid more slowly
than expected, the expected duration of the securities may be extended, reducing
the cash flow for potential reinvestment in higher yielding securities.

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

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

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 the fund's investment results for its first
full calendar year of operations, and the following table shows how the
fund's average annual total returns for its first full calendar year of
operations compare with a broad measure of market results. This information
provides some indication of the risks of investing in the fund. The Lipper
Short-Intermediate Investment Grade Debt Funds Average includes funds that
disclose investment objectives and/or strategies reasonably comparable to
the fund's objective and/or strategies. 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 calling
Capital Group Private Client Services at 800/421-4996.

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

shares through a tax-favored arrangement, such as a 401(k) plan or individual
retirement account (IRA).

preserving your investment.

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.

Shareholder fees (fees paid directly from your investment)

Shareholder Fees	Capital Core Municipal Fund Share class
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of the amount redeemed)	none
Maximum sales charge (load) imposed on reinvested dividends	none
Redemption or exchange fees	none

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Capital Core Municipal Fund Share class
Management fees		0.35%

Other expenses	[1]	0.07%
Total annual fund operating expenses		0.42%
Expense reimbursement	[2]	0.02%
Total annual fund operating expenses after reimbursement		0.40%

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.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Capital Core Municipal Fund Share class	41	133	233	528

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 13% of the average value of its portfolio.

Principal investment strategies

The fund seeks to achieve its objective by investing primarily in intermediate
maturity municipal bonds.

The fund will invest at least 80% of its assets in bonds (for purposes of this
limit, bonds include any debt instrument and cash equivalents, and may include
certain preferred securities). 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 federal income tax. The fund will not invest in
securities that subject you to the federal alternative minimum tax. The
investment adviser will seek to manage the fund in order to minimize capital
gain distributions.

The fund invests primarily in municipal bonds with quality ratings of A- or
better or A3 or better by Nationally Recognized Statistical Ratings Organizations
("NRSROs") 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 municipal bonds in the rating categories of BBB or Baa by NRSROs or
unrated but determined by the fund's investment adviser to be of equivalent
quality. Under normal circumstances the dollar-weighted average maturity of the
fund's portfolio will be between three and 10 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 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 due to market conditions and other factors,
including those directly involving the issuers of securities held by the fund.

Investing in bonds - Rising interest rates will generally cause the prices of
bonds and other debt securities to fall. Longer maturity debt securities may be
subject to greater price fluctuations than shorter maturity debt securities. In
addition, falling interest rates may cause an issuer to redeem, call or
refinance a security before its stated maturity, which may result in the fund
having to reinvest the proceeds in lower yielding securities.

Bonds and other debt securities are subject to credit risk, which is the
possibility that the credit strength of an issuer will weaken and/or an issuer
of a debt security will fail to make timely payments of principal or interest
and the security will go into default. Credit risk is gauged, in part, by the
credit ratings of the 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.

Credit and liquidity support - Changes in the credit quality of banks and
financial institutions providing credit and liquidity support features could
cause the fund to experience a loss and may affect its share price.

Investing in lower rated bonds - 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.

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

Investing in similar municipal bonds - Investing significantly in municipal
obligations of issuers in the same state or backed by revenues of similar types
of projects or industries may make 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 the fund's investment results for its first full
calendar year of operations, and the following table shows how the fund's
average annual total returns for its first full calendar year of operations
compare with a broad measure of market results. This information provides some
indication of the risks of investing in the fund. The Lipper Intermediate
Municipal Debt Funds Average includes funds that disclose investment objectives
and/or strategies reasonably comparable to the fund's objective and/or
strategies. 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 calling Capital Group Private Client Services at

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. 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 due to market conditions and other factors, including those directly involving the issuers of securities held by the fund. Investing in bonds - Rising interest rates will generally cause the prices of bonds and other debt securities to fall.

Strategy [Heading]	rr_StrategyHeading	Principal investment strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The fund primarily invests in intermediate-term debt securities, including securities issued and guaranteed by the U.S. government and securities backed by mortgages or other assets. The fund may also invest in debt securities and mortgage-backed securities issued by federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government. In addition, the fund may invest in asset-backed securities (securities backed by assets such as auto loans, credit card receivables or other providers of credit). The fund will invest at least 80% of its assets in bonds (for purposes of this limit, bonds include any debt instrument and cash equivalents, and may include certain preferred securities). The fund primarily invests in debt securities with quality ratings of A- or A3 or better by Nationally Recognized Statistical Ratings Organizations ("NRSROs") designated by the fund's investment adviser or unrated but determined to be of equivalent quality by the fund's investment adviser. The fund may invest up to 10% of its assets in debt securities rated in the BBB or Baa rating categories by NRSROs or unrated but determined to be of equivalent quality by the fund's investment adviser. Under normal circumstances, the dollar-weighted average maturity of the fund's portfolio will be between three and 10 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.

Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.
Risk [Heading]	rr_RiskHeading	Principal risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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 due to market conditions and other factors, including those directly involving the issuers of securities held by the fund. Investing in bonds - Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Longer maturity debt securities may be subject to greater price fluctuations than shorter maturity debt securities. In addition, falling interest rates may cause an issuer to redeem, call or refinance a security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Bonds and other debt securities are subject to credit risk, which is the possibility that the credit strength of an issuer will weaken and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Credit risk is gauged, in part, by the credit ratings of the 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. Investing in lower rated bonds - 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. Investing in mortgage-related securities - Many types of bonds and other debt securities, including mortgage-backed securities, are subject to prepayment risk as well as the risks associated with investing in debt securities in general. If interest rates fall and the loans underlying these securities are prepaid faster than expected, the fund may have to reinvest the prepaid principal in lower yielding securities, thus reducing the fund's income. Conversely, if interest rates increase and the loans underlying the securities are prepaid more slowly than expected, the expected duration of the securities may be extended, reducing the cash flow for potential reinvestment in higher yielding securities. Investing in securities backed by the U.S. government - Securities backed by the U.S. Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Securities issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are neither issued nor guaranteed by the U.S. government. Thinly traded securities - There may be little trading in the secondary market for particular bonds or other debt securities, which may make them more difficult to value, acquire or sell. 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.

Capital California Short-Term Municipal Fund (Prospectus Summary) | Capital California Short-Term Municipal Fund

Capital California Short-Term Municipal FundSM

Investment objectives

The fund seeks to preserve your investment

and secondarily to provide current income exempt from federal and California income taxes.

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.

Shareholder fees (fees paid directly from your investment)

Shareholder Fees	Capital California Short-Term Municipal Fund Share class
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of the amount redeemed)	none
Maximum sales charge (load) imposed on reinvested dividends	none
Redemption or exchange fees	none

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Capital California Short-Term Municipal Fund Share class
Management fees		0.35%
Distribution and/or service (12b-1) fees		none
Other expenses	[1]	0.12%
Total annual fund operating expenses		0.47%
Expense reimbursement	[2]	0.07%
Total annual fund operating expenses after reimbursement		0.40%

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.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Capital California Short-Term Municipal Fund Share class	41	144	256	585

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 14% of the average value of its portfolio.

Principal investment strategies

The fund seeks to achieve its objectives by primarily investing in short-term
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.

The fund will invest at least 80% of its assets in bonds (for purposes of this
limit, bonds include any debt instrument and cash equivalents, and may include
certain preferred securities). 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 federal and California income taxes. The
fund will not invest in securities that subject you to the federal alternative
minimum tax. The investment adviser will seek to manage the fund in order to
minimize capital gain distributions.

The fund invests primarily in municipal bonds with quality ratings of A- or A3
or better by Nationally Recognized Statistical Ratings Organizations ("NRSROs")
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
a portion of its assets in municipal bonds with quality ratings below A- or A3
by NRSROs or unrated but determined by the fund's investment adviser to be of
equivalent quality. Under normal circumstances, the fund's aggregate portfolio
will have a dollar-weighted average 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 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.

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 due to market conditions and other factors,
including those directly involving the issuers of securities held by the fund.

Investing in bonds - Rising interest rates will generally cause the prices of
bonds and other debt securities to fall. Longer maturity debt securities may be
subject to greater price fluctuations than shorter maturity debt securities. In
addition, falling interest rates may cause an issuer to redeem, call or
refinance a security before its stated maturity, which may result in the fund
having to reinvest the proceeds in lower yielding securities.

Bonds and other debt securities are subject to credit risk, which is the
possibility that the credit strength of an issuer will weaken and/or an issuer
of a debt security will fail to make timely payments of principal or interest
and the security will go into default. Credit risk is gauged, in part, by the
credit ratings of the 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.

Credit and liquidity support - Changes in the credit quality of banks and
financial institutions providing credit and liquidity support features could
cause the fund to experience a loss and may affect its share price.

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

Investing in similar municipal bonds - Investing significantly in municipal
obligations of issuers in the same state or backed by revenues of similar types
of projects or industries may make 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.

retirement account (IRA).

Capital California Core Municipal Fund (Prospectus Summary) | Capital California Core Municipal Fund

Capital California Core Municipal FundSM

Investment objective

The fund seeks to provide current income exempt from federal and California
income taxes while preserving your investment.

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.

Shareholder fees (fees paid directly from your investment)

Shareholder Fees (USD $)	Capital California Core Municipal Fund Share class
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of the amount redeemed)	none
Maximum sales charge (load) imposed on reinvested dividends	none
Redemption or exchange fees	none

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Capital California Core Municipal Fund Share class
Management fees		0.35%
Distribution and/or service (12b-1) fees		none
Other expenses	[1]	0.07%
Total annual fund operating expenses		0.42%
Expense reimbursement	[2]	0.02%
Total annual fund operating expenses after reimbursement		0.40%

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.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Capital California Core Municipal Fund Share class	41	133	233	528

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 21% of the average value of its portfolio.

Principal investment strategies

The fund seeks to achieve its objective by primarily investing in intermediate
maturity 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.

The fund will invest at least 80% of its assets in bonds (for purposes of this
limit, bonds include any debt instrument and cash equivalents, and may include
certain preferred securities). 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 federal and California income taxes. The fund
will not invest in securities that subject you to the federal alternative
minimum tax. The investment adviser will seek to manage the fund in order to
minimize capital gain distributions.

The fund invests primarily in municipal bonds with quality ratings of A- or A3
or better by Nationally Recognized Statistical Ratings Organizations ("NRSROs")
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 municipal bonds in the rating categories of BBB or Baa by NRSROs or unrated
but determined by the fund's investment adviser to be of equivalent quality.
Under normal circumstances, the dollar-weighted average maturity of the fund's
portfolio will be between three and 10 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 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.

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 due to market conditions and other factors,
including those directly involving the issuers of securities held by the fund.

Investing in bonds - Rising interest rates will generally cause the prices of
bonds and other debt securities to fall. Longer maturity debt securities may be
subject to greater price fluctuations than shorter maturity debt securities. In
addition, falling interest rates may cause an issuer to redeem, call or refinance
a security before its stated maturity, which may result in the fund having to
reinvest the proceeds in lower yielding securities.

Bonds and other debt securities are subject to credit risk, which is the
possibility that the credit strength of an issuer will weaken and/or an issuer
of a debt security will fail to make timely payments of principal or interest
and the security will go into default. Credit risk is gauged, in part, by the
credit ratings of the 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.

Credit and liquidity support - Changes in the credit quality of banks and
financial institutions providing credit and liquidity support features could
cause the fund to experience a loss and may affect its share price.

Investing in lower rated bonds - 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.

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

Investing in similar municipal bonds - Investing significantly in municipal
obligations of issuers in the same state or backed by revenues of similar types
of projects or industries may make 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.

The investment adviser also invests in companies with the potential to provide income in pursuing the fund's objectives. 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 valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.
Risk [Heading]	rr_RiskHeading	Principal risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. Market conditions - The prices of, and the income generated by, the securities held by the fund may decline due to market conditions and other factors, including those directly involving the issuers of securities held by the fund. Investing in growth-oriented stocks - Growth-oriented stocks may involve larger price swings and greater potential for loss than other types of investments. Investing outside the United States - Securities of issuers domiciled outside the United States, or with significant operations outside the United States, may lose value because of adverse political, social, economic or market developments in the countries or regions in which the issuer operates. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different settlement and accounting practices and different regulatory, legal and reporting standards, and may be more difficult to value, than those in the United States. The risks of investing outside the United States may be heightened in connection with investments in emerging markets. Management - The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the investment adviser in this process may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives. 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.
