T. Rowe Price Active Core International Equity ETF | Foreign investing [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity and trading volume than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. The fund’s overall foreign investing risk is increased to the extent it has exposure to emerging markets, which are more volatile than the markets of developed countries.

 

T. Rowe Price Active Core International Equity ETF | Quantitative models [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Quantitative models: The fund’s reliance on quantitative models and the analysis of specific metrics in constructing the fund’s portfolio could cause the adviser to be unsuccessful in selecting companies for investment or determining the weighting of particular stocks in the portfolio. The impact of these metrics on a stock’s performance can be difficult to predict, and stocks that previously possessed certain desirable quantitative characteristics may not continue to demonstrate those same characteristics in the future. In addition, relying on quantitative models entails the risk that the models themselves may be limited or incorrect, the data on which the models rely may be incorrect or incomplete, or the models may not be implemented as intended by the adviser. Any of these factors could cause the fund to underperform compared to funds with similar strategies that do not select stocks based on quantitative analysis.

 

T. Rowe Price Active Core International Equity ETF | Large- and mid-cap stocks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Large- and mid-cap stocks: Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by small-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges. The fund’s share price could fluctuate more than the share price of a fund that invests only in large-cap companies as stocks of mid-cap companies entail greater risk and are usually more volatile than stocks of large-cap companies.

Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry.

 

T. Rowe Price Active Core International Equity ETF | Market conditions [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

Information technology sector: Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins.

Risk [Text Block]

Authorized Participant: Only an Authorized Participant may engage in creation or redemption transactions directly with the fund. The fund has a limited number of intermediaries that act as Authorized Participants, and none of these Authorized Participants are or will be obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the fund and no other Authorized Participant is able to step forward to create or redeem, (i) the market price of the fund’s shares may trade at a premium or discount to its net asset value (NAV), (ii) an active trading market for the fund may not develop or be maintained, and (iii) there is no assurance that the requirements of the exchange necessary to maintain the listing of the fund will continue to be met or remain unchanged.

Prospectus [Line Items]  
Risk [Text Block]

ETF shares trading: Shares of the fund are listed for trading on a national securities exchange and are bought and sold in the secondary market at market prices. The market prices of shares are expected to fluctuate in response to changes in the fund’s NAV, the value of the fund’s holdings, and supply and demand for shares. Disruptions to creations and redemptions, significant market volatility, potential lack of an active trading market for the shares (including through a trading halt), or other factors may widen bid-ask spreads and result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the value of the fund’s holdings. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Risk [Text Block]

New fund: Because the fund is new, it has a relatively small number of shareholders and assets under management. As a result, the portfolio manager may experience difficulties in fully implementing the fund’s investment program and may be less able to respond to increases in shareholder transaction activity. The fund’s limited operating history could make it more difficult to evaluate the performance of the portfolio manager and the fund’s investment strategies. In addition, there can be no assurance that the fund will ultimately grow to an economically viable size, which could lead to the fund eventually ceasing its operations.

Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information.

Risk [Text Block]

Emerging markets: Investments in emerging market countries are subject to greater risk and overall volatility than investments in the U.S. and other developed markets. Emerging market countries tend to have economic structures that are less diverse and mature, less developed legal and regulatory regimes, and political systems that are less stable than those of developed countries. In addition to the risks associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on the fund’s investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates.

 

T. Rowe Price Emerging Markets Equity Research ETF | Investing in China [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Investing in China: The Chinese government has historically exercised significant control over China’s economy and its financial markets through, among other things, its monetary policies and allocation of resources, management of currency exchange rates, preferential treatment or restrictions relating to industries deemed sensitive to national interests, and limitations on foreign ownership of Chinese securities. Although economic reforms have liberalized trade policy and reduced government control, changes in these policies or increased government intervention could adversely impact affected industries or companies. China’s currency, which historically has been managed in a tight range relative to the U.S. dollar, may in the future be subject to greater uncertainty as Chinese authorities change the policies that determine the official currency exchange rate. Additionally, the Chinese economy is highly dependent on the exportation of products and services, and could experience a significant slowdown due to a reduction in global demand for Chinese exports, contraction in spending on domestic goods by Chinese consumers, trade or political disputes with China’s major trading partners, imposition of tariffs, sanctions, and other trade barriers, military conflict and strained international relations, cyberattacks, natural disasters, or public health threats. Heightened trade tensions between China and any of its key trading partners, including the U.S., could have a significant adverse impact on the Chinese economy.

Investing in Asia: Many Asian economies have at various times been negatively affected by inflation, currency devaluations, an over-reliance on international trade and exports, particularly for certain commodities, political and social instability, and less developed financial systems and securities trading markets. Trade restrictions, unexpected decreases in exports, changes in government policies, expropriation and/or nationalization of assets, confiscatory taxation, or natural disasters could have a significant impact on companies doing business in Asia. The Asian region may be significantly affected by political unrest, military conflict, economic sanctions, and less demand for Asian products and services.

 

T. Rowe Price Emerging Markets Equity Research ETF | Frontier markets [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Frontier markets: Frontier markets generally have smaller economies and less mature capital markets than emerging markets. As a result, the risks associated with investing in emerging market countries are magnified in frontier market countries. Frontier markets are more susceptible to abrupt changes in currency values, have less mature markets and settlement practices, and can have lower trading volumes that could lead to greater price volatility and illiquidity. Investor protections in frontier market countries may be limited and settlement procedures and custody services may prove inadequate in certain markets.

 

T. Rowe Price Emerging Markets Equity Research ETF | Currency exposure [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Currency exposure: Because the fund invests in holdings denominated in foreign currencies, the fund is subject to the significant risk that it could experience losses based solely on the weakness of foreign currencies versus the U.S. dollar and changes in the exchange rates between such currencies and the U.S. dollar.

 

T. Rowe Price Emerging Markets Equity Research ETF | Financial sector [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Financial sector: Because the fund may invest significantly in banks and other financial services companies, the fund is more susceptible to adverse developments affecting such companies and may perform poorly during a downturn that impacts the financial sector. Banks and other financial services companies can be adversely affected by, among other things, regulatory changes, interest rate movements, the availability of capital and cost to borrow, and the rate of debt defaults.

 

T. Rowe Price Emerging Markets Equity Research ETF | Index correlation [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Index correlation: Because the fund weights each sector and industry similar to the Index, the fund’s ability to broadly reallocate its portfolio due to changes in outlook for a particular sector or industry is less than other actively managed funds with greater flexibility to overweight or underweight certain industries due to changes in market conditions. As a result, the fund’s performance may lag the performance of other actively managed funds with more flexible investment programs.

T. Rowe Price High Income Municipal ETF | Municipal securities [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Municipal securities: The fund may be highly impacted by events tied to the overall municipal securities markets, which can be very volatile and significantly affected by unfavorable legislative or political developments and adverse changes in the financial conditions of municipal securities issuers and the global, national, and/or local economies. Income from municipal securities held by the fund could become taxable because of changes in tax laws or interpretations by taxing authorities, or noncompliant conduct of a state or municipality. Other changes in tax laws, including changes to individual or corporate tax rates, could alter the attractiveness and overall demand for municipal bonds.

 

Certain sectors of the municipal bond market have special risks and could be affected by certain developments more significantly than the market as a whole. For example: health care can be negatively impacted by rising expenses and dependency on third party reimbursements; transportation can be negatively impacted by declining revenues or unexpectedly high construction or fuel costs; utilities are subject to governmental rate regulation; and private activity bonds (including industrial development bonds) rely on project revenues and the creditworthiness of the corporate user as opposed to governmental support. Investing significantly in municipal obligations backed by revenues of similar types of industries or projects may make the fund more susceptible to developments affecting those industries and projects. If the fund invests a substantial amount of its assets in issuers located in a single region, state, or city, there is an increased risk that environmental, economic, political, and social conditions in those regions will have a significant impact on the fund’s investment performance.

Alternative minimum tax: Although the fund seeks to distribute tax-exempt income, a portion of the fund’s otherwise tax-exempt dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

 

T. Rowe Price High Income Municipal ETF | Credit quality [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Credit quality: An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative. Economic downturns often result in reduced levels of taxes collected and revenues earned by municipalities and insufficient funding to meet pension or health care obligations, which could lessen the overall financial strength of a municipality and increase the credit risk of the securities it issues. The fund’s credit risk is increased to the extent it invests in securities that are not backed by the taxing power of the municipal issuer.

 

T. Rowe Price High Income Municipal ETF | Junk bonds [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Junk bonds: Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, expose the fund to greater volatility and credit risk than investments in bonds that are rated investment grade. As a result, bonds rated below investment grade carry a higher risk of default and should be considered speculative.

Interest rates: A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests.

Liquidity: The fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. The secondary market for certain municipal bonds tends to be less developed and less liquid than many other bond markets. Less liquid markets could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price.

Foreign investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity and trading volume than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. The fund’s overall foreign investing risk is increased to the extent it has exposure to emerging markets, which are more volatile than the markets of developed countries.

Large- and mid-cap stocks: Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by small-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges. The fund’s share price could fluctuate more than the share price of a fund that invests only in large-cap companies as stocks of mid-cap companies entail greater risk and are usually more volatile than stocks of large-cap companies.

Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others.

Risk [Text Block]

Municipal securities: The fund may be highly impacted by events tied to the overall municipal securities markets, which can be very volatile and significantly affected by unfavorable legislative or political developments and adverse changes in the financial conditions of municipal securities issuers and the global, national, and/or local economies. Income from municipal securities held by the fund could become taxable because of changes in tax laws or interpretations by taxing authorities, or noncompliant conduct of a state or municipality. Other changes in tax laws, including changes to individual or corporate tax rates, could alter the attractiveness and overall demand for municipal bonds.

 

Certain sectors of the municipal bond market have special risks and could be affected by certain developments more significantly than the market as a whole. For example: health care can be negatively impacted by rising expenses and dependency on third party reimbursements; transportation can be negatively impacted by declining revenues or unexpectedly high construction or fuel costs; utilities are subject to governmental rate regulation; and private activity bonds (including industrial development bonds) rely on project revenues and the creditworthiness of the corporate user as opposed to governmental support. Investing significantly in municipal obligations backed by revenues of similar types of industries or projects may make the fund more susceptible to developments affecting those industries and projects. If the fund invests a substantial amount of its assets in issuers located in a single region, state, or city, there is an increased risk that environmental, economic, political, and social conditions in those regions will have a significant impact on the fund’s investment performance.

Economic downturns often result in reduced levels of taxes collected and revenues earned by municipalities and insufficient funding to meet pension or health care obligations, which could lessen the overall financial strength of a municipality and increase the credit risk of the securities it issues. The fund’s credit risk is increased to the extent it invests in securities that are not backed by the taxing power of the municipal issuer.

Prepayments and extensions: Underlying funds that invest in mortgage-backed securities, certain asset-backed securities, or any debt instrument with an embedded call option are subject to prepayment risks because the principal on the security may be prepaid at any time, which could reduce the security’s yield and market value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the underlying fund’s portfolio to shorten. Extension risk may result from a rise in interest rates, which tends to make mortgage-backed securities, asset-backed securities, and other callable debt instruments more volatile.

Prospectus [Line Items]  
Risk [Text Block]

Bank loans: Investments in bank loans expose the fund to additional risks beyond those normally associated with more traditional debt instruments. The fund’s ability to receive payments in connection with a loan depends primarily on the financial condition of the borrower and whether or not a loan is secured by collateral, although there is no assurance that the collateral securing a loan will be sufficient to satisfy the loan obligation. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. Transactions involving bank loans may have significantly longer settlement periods than more traditional investments (settlement can take longer than 7 days) and often involve borrowers whose financial condition is troubled or highly leveraged, which increases the risk that the fund may not receive its proceeds in a timely manner or that the fund may incur losses in order to pay redemption proceeds to its shareholders. In addition, loans are not registered under the federal securities laws like stocks and bonds, so investors in loans have less protection against improper practices than investors in registered securities.

Derivatives: The use of derivatives exposes the fund to additional volatility and potential losses. A derivative involves risks different from, and possibly greater than, the risks associated with investing directly in the assets on which the derivative is based, including liquidity risk, valuation risk, correlation risk, market risk, interest rate risk, leverage risk, counterparty and credit risk, operational risk, management risk, legal risk, and regulatory risk. Derivatives can be highly volatile, illiquid, and difficult to value, and changes in the value of a derivative may not properly correlate with changes in the value of the underlying asset, reference rate, or index. The fund could be exposed to significant losses if it is unable to close a derivatives position due to the lack of a liquid secondary trading market. The prices of derivatives may move in unexpected ways, especially in abnormal market conditions. Certain derivatives are also subject to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations. The use of derivatives includes the risk of potential operational issues, such as settlement issues. Derivatives are exposed to legal risks, such as the legality or enforceability of a contract. The adviser may not be able to accurately predict the direction of prices, economic factors, or other associated risks which could cause loss in value or impair the fund’s efforts to reduce overall volatility. New regulations may make derivatives more costly, limit availability, or otherwise affect their value or performance.

Prospectus [Line Items]  
Risk [Text Block]

Inflation-linked securities: In general, the value of an inflation-linked security, including TIPS, will typically decrease when real interest rates (nominal interest rates reduced by the expected impact of inflation) increase and increase when real interest rates decrease. When inflation is negative or concerns over inflation are low, the value and income of inflation-linked securities could fall and result in losses for the fund and during periods of very low inflation, the yield on an inflation-linked security may be negative. Conversely, during sustained periods of high inflation, the fund’s yield should increase, which may not be repeated. Funds that invest heavily in inflation-linked securities do not always move in lockstep with inflation because they do not necessarily buy inflation-linked securities when they are originally issued or hold them until maturity. In addition, the accrual of inflation adjustments on the fund’s holdings may significantly impact the current level of dividends actually paid to shareholders. Changes in inflation rates and/or interest rates may cause the fund’s yield to vary substantially over time.

Portfolio turnover: High portfolio turnover may adversely affect the fund’s performance and increase transaction costs, which could increase the fund’s expenses. High portfolio turnover may also result in the distribution of higher capital gains when compared with a fund with less active trading policies, which could have an adverse tax impact if the fund’s shares are held in a taxable account.

Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

Authorized Participant: Only an Authorized Participant may engage in creation or redemption transactions directly with the fund. The fund has a limited number of intermediaries that act as Authorized Participants, and none of these Authorized Participants are or will be obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the fund and no other Authorized Participant is able to step forward to create or redeem, (i) the market price of the fund’s shares may trade at a premium or discount to its net asset value (NAV), (ii) an active trading market for the fund may not develop or be maintained, and (iii) there is no assurance that the requirements of the exchange necessary to maintain the listing of the fund will continue to be met or remain unchanged.

 

T. Rowe Price Short Municipal Income ETF | ETF shares trading [Member]

Risk [Text Block]

ETF shares trading: Shares of the fund are listed for trading on a national securities exchange and are bought and sold in the secondary market at market prices. The market prices of shares are expected to fluctuate in response to changes in the fund’s NAV, the value of the fund’s holdings, and supply and demand for shares. Disruptions to creations and redemptions, significant market volatility, potential lack of an active trading market for the shares (including through a trading halt), or other factors may widen bid-ask spreads and result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the value of the fund’s holdings. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Risk [Text Block]

New fund: Because the fund is new, it has a relatively small number of shareholders and assets under management. As a result, the portfolio manager may experience difficulties in fully implementing the fund’s investment program and may be less able to respond to increases in shareholder transaction activity. The fund’s limited operating history could make it more difficult to evaluate the performance of the portfolio manager and the fund’s investment strategies. In addition, there can be no assurance that the fund will ultimately grow to an economically viable size, which could lead to the fund eventually ceasing its operations.

Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality.

Prospectus [Line Items]  
Risk [Text Block]

Municipal securities: The fund may be highly impacted by events tied to the overall municipal securities markets, which can be very volatile and significantly affected by unfavorable legislative or political developments and adverse changes in the financial conditions of municipal securities issuers and the global, national, and/or local economies. Income from municipal securities held by the fund could become taxable because of changes in tax laws or interpretations by taxing authorities, or noncompliant conduct of a state or municipality. Other changes in tax laws, including changes to individual or corporate tax rates, could alter the attractiveness and overall demand for municipal bonds.

 

Certain sectors of the municipal bond market have special risks and could be affected by certain developments more significantly than the market as a whole. For example: health care can be negatively impacted by rising expenses and dependency on third party reimbursements; transportation can be negatively impacted by declining revenues or unexpectedly high construction or fuel costs; utilities are subject to governmental rate regulation; and private activity bonds (including industrial development bonds) rely on project revenues and the creditworthiness of the corporate user as opposed to governmental support. Investing significantly in municipal obligations backed by revenues of similar types of industries or projects may make the fund more susceptible to developments affecting those industries and projects. If the fund invests a substantial amount of its assets in issuers located in a single region, state, or city, there is an increased risk that environmental, economic, political, and social conditions in those regions will have a significant impact on the fund’s investment performance.

Alternative minimum tax: Although the fund seeks to distribute tax-exempt income, a portion of the fund’s otherwise tax-exempt dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Risk [Text Block]

Credit quality: An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative. Economic downturns often result in reduced levels of taxes collected and revenues earned by municipalities and insufficient funding to meet pension or health care obligations, which could lessen the overall financial strength of a municipality and increase the credit risk of the securities it issues. The fund’s credit risk is increased to the extent it invests in securities that are not backed by the taxing power of the municipal issuer.

Junk bonds: Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, expose the fund to greater volatility and credit risk than investments in bonds that are rated investment grade. As a result, bonds rated below investment grade carry a higher risk of default and should be considered speculative.

Interest rates: A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests.

Callable bonds: While a rise in interest rates is the principal source of interest rate risk for bond funds, falling rates bring the possibility that a bond may be “called,” or redeemed before maturity, and that the proceeds may need to be reinvested in lower-yielding securities.

Risk [Text Block]

Liquidity: The fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. The secondary market for certain municipal bonds tends to be less developed and less liquid than many other bond markets. Less liquid markets could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price.
