FRANKLIN FEDERAL INTERMEDIATE-TERM TAX-FREE INCOME FUND

Risk Table - FRANKLIN FEDERAL INTERMEDIATE-TERM TAX-FREE INCOME FUND	Risk [Text Block]
Principal Risks	Principal Risks You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Risk Lose Money [Member]	You could lose money by investing in the Fund.
Risk Not Insured [Member]	Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Interest Rate	Interest Rate: When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.
Credit	Credit: An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value. A change in the credit rating of a municipal bond insurer that insures securities in the Fund’s portfolio may affect the value of the securities it insures, the Fund’s share price and Fund performance. The Fund might also be adversely impacted by the inability of an insurer to meet its insurance obligations.
Liquidity	Liquidity: The trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.
Tax Legislative and Political Changes	Tax Legislative and Political Changes: The municipal securities market could be significantly affected by adverse political and legislative changes or litigation at the federal or state level. The value of municipal bonds is closely tied to the benefits of tax-exempt income to investors. Significant revisions of federal income tax laws or regulations revising income tax rates or the tax-exempt character of municipal bonds, or even proposed changes and deliberations on this topic by the federal government, could cause municipal bond prices to fall. For example, lower federal income tax rates would reduce certain relative advantages of owning municipal bonds, and lower state income tax rates could have similar effects. In addition, the application of corporate minimum tax rates to financial statement income may have the effect of reducing demand for municipal bonds among corporate investors, which may in turn impact municipal bond prices.
Tax-Exempt Securities	Tax-Exempt Securities: Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.
Market	Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in tariffs, trade barriers and investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
States	States: The Fund’s portfolio is generally widely diversified among issuers of municipal securities. However, to the extent that the Fund has exposure from time to time to the municipal securities of a particular state, events in that state may affect the Fund’s investments and performance. These events may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of the state. The same is true of events in U.S. territories, to the extent that the Fund has exposure to any particular territory at any given time.
Focus	Focus: The Fund may invest more than 25% of its assets in municipal securities that finance similar types of projects, such as utilities, hospitals, higher education and transportation. A change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.
Income	Income: The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.
Prepayment	Prepayment: Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.
Inflation	Inflation: The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund. Debt securities that pay a fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate debt securities may be able to participate, over the long term, in rising interest rates which have historically corresponded with long-term inflationary trends.
Bond Insurers	Bond Insurers: Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially limited the availability of insurance sought by municipal bond issuers thereby reducing the supply of insured municipal securities. Because of the consolidation among municipal bond insurers the Fund is subject to additional risks including the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.
Unrated Debt Securities	Unrated Debt Securities: Unrated debt securities determined by the investment manager to be of comparable credit quality to rated securities which the Fund may purchase may pay a higher interest rate than such rated debt securities and be subject to a greater risk of illiquidity or price changes. Less public information and independent credit analysis are typically available about unrated securities or issuers, and therefore they may be subject to greater risk of default.
Management	Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
Cybersecurity	Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
High-Yield Debt Instruments	High-Yield Debt Instruments: Issuers of lower-rated or “high-yield” debt instruments (also known as “junk bonds”) are not as strong financially as those issuing higher credit quality debt instruments. High-yield debt instruments are generally considered predominantly speculative by the applicable rating agencies as their issuers are more likely to encounter financial difficulties because they may be more highly leveraged, or because of other considerations. In addition, high yield debt instruments generally are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high-yield debt instruments generally fluctuate more than those of higher credit quality. High-yield debt instruments are generally more illiquid (harder to sell) and harder to value.
States	States: The Fund’s portfolio is generally widely diversified among issuers of municipal securities. However, to the extent that the Fund has exposure from time to time to the municipal securities of a particular state, events in that state may affect the Fund’s investments and performance.

Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
Massachusetts	Massachusetts: The Fund invests predominantly in Massachusetts municipal securities. Therefore, events in Massachusetts are likely to affect the Fund’s investments and its performance.

Less public information and independent credit analysis are typically available about unrated securities or issuers, and therefore they may be subject to greater risk of default.
Management	Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
Cybersecurity	Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

FRANKLIN NEW JERSEY TAX-FREE INCOME FUND

Risk Table - FRANKLIN NEW JERSEY TAX-FREE INCOME FUND	Risk [Text Block]
Principal Risks	Principal Risks You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Risk Lose Money [Member]	You could lose money by investing in the Fund.
Risk Not Insured [Member]	Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Interest Rate	Interest Rate: When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.
Credit	Credit: An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value. A change in the credit rating of a municipal bond insurer that insures securities in the Fund’s portfolio may affect the value of the securities it insures, the Fund’s share price and Fund performance. The Fund might also be adversely impacted by the inability of an insurer to meet its insurance obligations.
Liquidity	Liquidity: The trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.
Tax Legislative and Political Changes	Tax Legislative and Political Changes: The municipal securities market could be significantly affected by adverse political and legislative changes or litigation at the federal or state level. The value of municipal bonds is closely tied to the benefits of tax-exempt income to investors. Significant revisions of federal income tax laws or regulations revising income tax rates or the tax-exempt character of municipal bonds, or even proposed changes and deliberations on this topic by the federal government, could cause municipal bond prices to fall. For example, lower federal income tax rates would reduce certain relative advantages of owning municipal bonds, and lower state income tax rates could have similar effects. In addition, the application of corporate minimum tax rates to financial statement income may have the effect of reducing demand for municipal bonds among corporate investors, which may in turn impact municipal bond prices.
Tax-Exempt Securities	Tax-Exempt Securities: Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.
Market	Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in tariffs, trade barriers and investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
New Jersey	New Jersey: The Fund invests predominantly in New Jersey municipal securities. Therefore, events in New Jersey are likely to affect the Fund’s investments and its performance. These events may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of New Jersey. The same is true of events in other states or U.S. territories, to the extent that the Fund has exposure to any other state or territory at any given time.
Focus	Focus: The Fund may invest more than 25% of its assets in municipal securities that finance similar types of projects, such as utilities, hospitals, higher education and transportation. A change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.
Income	Income: The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.
Prepayment	Prepayment: Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.
Inflation	Inflation: The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund. Debt securities that pay a fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate debt securities may be able to participate, over the long term, in rising interest rates which have historically corresponded with long-term inflationary trends.
Bond Insurers	Bond Insurers: Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially limited the availability of insurance sought by municipal bond issuers thereby reducing the supply of insured municipal securities. Because of the consolidation among municipal bond insurers the Fund is subject to additional risks including the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.

Debt securities that pay a fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate debt securities may be able to participate, over the long term, in rising interest rates which have historically corresponded with long-term inflationary trends.
Bond Insurers	Bond Insurers: Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially limited the availability of insurance sought by municipal bond issuers thereby reducing the supply of insured municipal securities. Because of the consolidation among municipal bond insurers the Fund is subject to additional risks including the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.
Unrated Debt Securities	Unrated Debt Securities: Unrated debt securities determined by the investment manager to be of comparable credit quality to rated securities which the Fund may purchase may pay a higher interest rate than such rated debt securities and be subject to a greater risk of illiquidity or price changes. Less public information and independent credit analysis are typically available about unrated securities or issuers, and therefore they may be subject to greater risk of default.
Management	Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
Cybersecurity	Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

Principal Risks	Principal Risks You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Risk Lose Money [Member]	You could lose money by investing in the Fund.
Risk Not Insured [Member]	Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Interest Rate	Interest Rate: When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.
Credit	Credit: An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value. A change in the credit rating of a municipal bond insurer that insures securities in the Fund’s portfolio may affect the value of the securities it insures, the Fund’s share price and Fund performance. The Fund might also be adversely impacted by the inability of an insurer to meet its insurance obligations.
Liquidity	Liquidity: The trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.
Tax Legislative and Political Changes	Tax Legislative and Political Changes: The municipal securities market could be significantly affected by adverse political and legislative changes or litigation at the federal or state level. The value of municipal bonds is closely tied to the benefits of tax-exempt income to investors. Significant revisions of federal income tax laws or regulations revising income tax rates or the tax-exempt character of municipal bonds, or even proposed changes and deliberations on this topic by the federal government, could cause municipal bond prices to fall. For example, lower federal income tax rates would reduce certain relative advantages of owning municipal bonds, and lower state income tax rates could have similar effects. In addition, the application of corporate minimum tax rates to financial statement income may have the effect of reducing demand for municipal bonds among corporate investors, which may in turn impact municipal bond prices.
Tax-Exempt Securities	Tax-Exempt Securities: Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.
Market	Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in tariffs, trade barriers and investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
Maryland	Maryland: The Fund invests predominantly in Maryland municipal securities. Therefore, events in Maryland are likely to affect the Fund’s investments and its performance. These events may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Maryland. The same is true of events in other states or U.S. territories, to the extent that the Fund has exposure to any other state or territory at any given time.
Focus	Focus: The Fund may invest more than 25% of its assets in municipal securities that finance similar types of projects, such as utilities, hospitals, higher education and transportation. A change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.
Income	Income: The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.
Prepayment	Prepayment: Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.
Inflation	Inflation: The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund.

Income	Income: The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.
Prepayment	Prepayment: Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.
Inflation	Inflation: The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund. Debt securities that pay a fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate debt securities may be able to participate, over the long term, in rising interest rates which have historically corresponded with long-term inflationary trends.
Bond Insurers	Bond Insurers: Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially limited the availability of insurance sought by municipal bond issuers thereby reducing the supply of insured municipal securities. Because of the consolidation among municipal bond insurers the Fund is subject to additional risks including the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.
Unrated Debt Securities	Unrated Debt Securities: Unrated debt securities determined by the investment manager to be of comparable credit quality to rated securities which the Fund may purchase may pay a higher interest rate than such rated debt securities and be subject to a greater risk of illiquidity or price changes. Less public information and independent credit analysis are typically available about unrated securities or issuers, and therefore they may be subject to greater risk of default.
Management	Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
Cybersecurity	Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

Risk Not Insured [Member]	Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Interest Rate	Interest Rate: When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.
Credit	Credit: An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value. A change in the credit rating of a municipal bond insurer that insures securities in the Fund’s portfolio may affect the value of the securities it insures, the Fund’s share price and Fund performance. The Fund might also be adversely impacted by the inability of an insurer to meet its insurance obligations.
Liquidity	Liquidity: The trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.
Tax Legislative and Political Changes	Tax Legislative and Political Changes: The municipal securities market could be significantly affected by adverse political and legislative changes or litigation at the federal or state level. The value of municipal bonds is closely tied to the benefits of tax-exempt income to investors. Significant revisions of federal income tax laws or regulations revising income tax rates or the tax-exempt character of municipal bonds, or even proposed changes and deliberations on this topic by the federal government, could cause municipal bond prices to fall. For example, lower federal income tax rates would reduce certain relative advantages of owning municipal bonds, and lower state income tax rates could have similar effects. In addition, the application of corporate minimum tax rates to financial statement income may have the effect of reducing demand for municipal bonds among corporate investors, which may in turn impact municipal bond prices.
Tax-Exempt Securities	Tax-Exempt Securities: Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.
Market	Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in tariffs, trade barriers and investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
Arizona	Arizona: The Fund invests predominantly in Arizona municipal securities. Therefore, events in Arizona are likely to affect the Fund’s investments and its performance. These events may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Arizona. The same is true of events in other states or U.S. territories, to the extent that the Fund has exposure to any other state or territory at any given time.

In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in tariffs, trade barriers and investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
Michigan	Michigan: The Fund invests predominantly in Michigan municipal securities. Therefore, events in Michigan are likely to affect the Fund’s investments and its performance. These events may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Michigan. The same is true of events in other states or U.S. territories, to the extent that the Fund has exposure to any other state or territory at any given time.
Focus	Focus: The Fund may invest more than 25% of its assets in municipal securities that finance similar types of projects, such as utilities, hospitals, higher education and transportation. A change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.
Income	Income: The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.
Prepayment	Prepayment: Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.
Inflation	Inflation: The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund. Debt securities that pay a fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate debt securities may be able to participate, over the long term, in rising interest rates which have historically corresponded with long-term inflationary trends.
Bond Insurers	Bond Insurers: Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially limited the availability of insurance sought by municipal bond issuers thereby reducing the supply of insured municipal securities. Because of the consolidation among municipal bond insurers the Fund is subject to additional risks including the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.
Unrated Debt Securities	Unrated Debt Securities: Unrated debt securities determined by the investment manager to be of comparable credit quality to rated securities which the Fund may purchase may pay a higher interest rate than such rated debt securities and be subject to a greater risk of illiquidity or price changes. Less public information and independent credit analysis are typically available about unrated securities or issuers, and therefore they may be subject to greater risk of default.
Management	Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
Cybersecurity	Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

Principal Risks	Principal Risks You could lose money by investing in the Fund.

Risk Not Insured [Member]	Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.
Interest Rate	Interest Rate: When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.
Credit	Credit: An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value. A change in the credit rating of a municipal bond insurer that insures securities in the Fund’s portfolio may affect the value of the securities it insures, the Fund’s share price and Fund performance. The Fund might also be adversely impacted by the inability of an insurer to meet its insurance obligations.
Liquidity	Liquidity: The trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.
Tax Legislative and Political Changes	Tax Legislative and Political Changes: The municipal securities market could be significantly affected by adverse political and legislative changes or litigation at the federal or state level. The value of municipal bonds is closely tied to the benefits of tax-exempt income to investors. Significant revisions of federal income tax laws or regulations revising income tax rates or the tax-exempt character of municipal bonds, or even proposed changes and deliberations on this topic by the federal government, could cause municipal bond prices to fall. For example, lower federal income tax rates would reduce certain relative advantages of owning municipal bonds, and lower state income tax rates could have similar effects. In addition, the application of corporate minimum tax rates to financial statement income may have the effect of reducing demand for municipal bonds among corporate investors, which may in turn impact municipal bond prices.
Tax-Exempt Securities	Tax-Exempt Securities: Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.
Market	Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer.

Tax-Exempt Securities	Tax-Exempt Securities: Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.
Market	Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in tariffs, trade barriers and investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.
Pennsylvania	Pennsylvania: The Fund invests predominantly in Pennsylvania municipal securities. Therefore, events in Pennsylvania are likely to affect the Fund’s investments and its performance. These events may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Pennsylvania. The same is true of events in other states or U.S. territories, to the extent that the Fund has exposure to any other state or territory at any given time.
Focus	Focus: The Fund may invest more than 25% of its assets in municipal securities that finance similar types of projects, such as utilities, hospitals, higher education and transportation. A change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.
Income	Income: The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.
Prepayment	Prepayment: Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.
Inflation	Inflation: The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund. Debt securities that pay a fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate debt securities may be able to participate, over the long term, in rising interest rates which have historically corresponded with long-term inflationary trends.
Bond Insurers	Bond Insurers: Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially limited the availability of insurance sought by municipal bond issuers thereby reducing the supply of insured municipal securities. Because of the consolidation among municipal bond insurers the Fund is subject to additional risks including the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.
Unrated Debt Securities	Unrated Debt Securities: Unrated debt securities determined by the investment manager to be of comparable credit quality to rated securities which the Fund may purchase may pay a higher interest rate than such rated debt securities and be subject to a greater risk of illiquidity or price changes. Less public information and independent credit analysis are typically available about unrated securities or issuers, and therefore they may be subject to greater risk of default.
Management	Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
Cybersecurity	Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.
