Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6.73% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, the Fund normally invests at least 80% of its net assets in securities whose interest is free from state personal income taxes. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund is a non-diversified fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund. The Fund focuses on the municipal securities of U.S. territories and currently primarily invests in Puerto Rican municipal securities

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Puerto Rico and U.S. Territories

Because the Fund focuses on the municipal securities of U.S. territories, and currently invests primarily in Puerto Rican municipal securities, events in Puerto Rico are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, territory constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to Puerto Rico's municipal issuers. As with Puerto Rican municipal securities, events in any of the other territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

Non-Diversification

Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting similar issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Fund’s shares and greater risk of loss.

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.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting similar issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Fund’s shares and greater risk of loss

Historical performance for Advisor Class shares prior to their inception is based on the performance of Class A shares. Advisor Class performance has been adjusted to reflect differences in sales charges between classes.

The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

Although the Fund does not have restrictions on the maturity of the securities it may buy, the Fund does maintain a dollar-weighted average portfolio maturity of three to 10 years.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund does not necessarily focus its investments in a particular state. The Fund may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

States and U.S. Territories

The Fund’s portfolio is generally widely diversified among issuers of municipal securities. From time to time, however, the Fund may have a significant position in the municipal securities of a particular state or territory. Under these circumstances, changes in the economic conditions in that state or territory are likely to affect the Fund’s investments and performance.

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.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

Although the Fund does not have restrictions on the maturity of the securities it may buy, the Fund does maintain a dollar-weighted average portfolio maturity of five years or less.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund does not necessarily focus its investments in a particular state. The Fund may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

States and U.S. Territories

The Fund’s portfolio is generally widely diversified among issuers of municipal securities. From time to time, however, the Fund may have a significant position in the municipal securities of a particular state or territory. Under these circumstances, changes in the economic conditions in that state or territory are likely to affect the Fund’s investments and performance.

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.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund may invest in municipal securities rated in any rating category, including defaulted securities.

The Fund does not necessarily focus its investments in a particular state and will not invest more than 25% of its total assets in municipal securities of any one state or territory. The Fund may invest up to 35% of its assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

When selecting securities for the Fund’s portfolio, the investment manager may consider existing market conditions, the availability of lower-rated securities, and whether the difference in yields between higher and lower-rated securities justifies the higher risk of lower-rated securities.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

High-Yield Debt Securities

Issuers of lower-rated or "high-yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and 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 securities generally fluctuate more than those of higher credit quality. High-yield debt securities are generally more illiquid (harder to sell) and harder to value.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

States and U.S. Territories

The Fund’s portfolio is generally widely diversified among issuers of municipal securities. From time to time, however, the Fund may have a significant position in the municipal securities of a particular state or territory. Under these circumstances, changes in the economic conditions in that state or territory are likely to affect the Fund’s investments and performance.

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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its net assets in insured municipal securities. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. Generally, under normal market conditions and to the extent available, the Fund seeks to invest in insured municipal securities covered by policies issued by municipal bond insurers rated at least BBB. The Fund generally purchases bonds that have insurance in place so it does not pay insurance premiums directly. The premium costs, however, are reflected in a lower yield and/or higher price for the insured bond. When beneficial, the Fund may purchase insurance for an uninsured bond directly from a qualified municipal bond insurer, in which case the Fund pays the insurance premium directly to the insurance company. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories. The Fund will not invest more than 25% of its total assets in municipal securities of any one state or territory.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Bond Insurers

Market conditions or changes to ratings criteria could continue to 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 which meet the Fund's investment guidelines.

Recent market conditions have led to a consolidation among municipal bond insurers that may lead to a concentration of insurance company credit risk among fewer insurers.

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.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 14.50% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Massachusetts. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Because of its historical investment policy of investing in insured municipal securities, the Fund’s portfolio may consist to a large extent of insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. The premium costs, however, are typically reflected in a lower yield and/or higher price for the insured bond. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Bond Insurers

Market conditions or changes to ratings criteria could continue to 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.

Recent market conditions have led to a consolidation among municipal bond insurers that may lead to a concentration of insurance company credit risk among fewer insurers.

Massachusetts and U.S. Territories

Because the Fund invests predominantly in Massachusetts municipal securities, events in Massachusetts are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Massachusetts. As with Massachusetts municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

New Jersey and U.S. Territories

Because the Fund invests predominantly in New Jersey municipal securities, 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, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of New Jersey. As with New Jersey municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6.48% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Florida. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Florida and U.S. Territories

Because the Fund invests predominantly in Florida municipal securities, events in Florida are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Florida. As with Florida municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Georgia. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Georgia and U.S. Territories

Because the Fund invests predominantly in Georgia municipal securities, events in Georgia are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Georgia. As with Georgia municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Kentucky. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Kentucky and U.S. Territories

Because the Fund invests predominantly in Kentucky municipal securities, events in Kentucky are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Kentucky. As with Kentucky municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Maryland. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Maryland and U.S. Territories

Because the Fund invests predominantly in Maryland municipal securities, 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, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Maryland. As with Maryland municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Missouri and U.S. Territories

Because the Fund invests predominantly in Missouri municipal securities, events in Missouri are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Missouri. As with Missouri municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6.13% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of North Carolina. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Objective [Heading]

rr_ObjectiveHeading

Investment Goal

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

To provide investors with as high a level of income exempt from federal income taxes as is consistent with prudent investment management and the preservation of shareholders’ capital. The Fund also tries to provide a maximum level of income exempt from personal income taxes, if any, for resident shareholders of Virginia.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 11.58% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Virginia. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Virginia and U.S. Territories

Because the Fund invests predominantly in Virginia municipal securities, events in Virginia are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Virginia. As with Virginia municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Arizona. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Arizona and U.S. Territories

Because the Fund invests predominantly in Arizona municipal securities, 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, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Arizona. As with Arizona municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 8.14% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Colorado. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Colorado and U.S. Territories

Because the Fund invests predominantly in Colorado municipal securities, events in Colorado are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Colorado. As with Colorado municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Connecticut and U.S. Territories

Because the Fund invests predominantly in Connecticut municipal securities, events in Connecticut are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Connecticut. As with Connecticut municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 0.92% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Michigan. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Because of its historical investment policy of investing in insured municipal securities, the Fund’s portfolio may consist to a large extent of insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. The premium costs, however, are typically reflected in a lower yield and/or higher price for the insured bond. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

rr_StrategyPortfolioConcentration

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Bond Insurers

Market conditions or changes to ratings criteria could continue to 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.

Recent market conditions have led to a consolidation among municipal bond insurers that may lead to a concentration of insurance company credit risk among fewer insurers.

Michigan and U.S. Territories

Because the Fund invests predominantly in Michigan municipal securities, 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, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Michigan. As with Michigan municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 5.32% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Minnesota. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Because of its historical investment policy of investing in insured municipal securities, the Fund’s portfolio may consist to a large extent of insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. The premium costs, however, are typically reflected in a lower yield and/or higher price for the insured bond. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Bond Insurers

Market conditions or changes to ratings criteria could continue to 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.

Recent market conditions have led to a consolidation among municipal bond insurers that may lead to a concentration of insurance company credit risk among fewer insurers.

Minnesota and U.S. Territories

Because the Fund invests predominantly in Minnesota municipal securities, events in Minnesota are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Minnesota. As with Minnesota municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Ohio. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Because of its historical investment policy of investing in insured municipal securities, the Fund’s portfolio may consist to a large extent of insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. The premium costs, however, are typically reflected in a lower yield and/or higher price for the insured bond. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Bond Insurers

Market conditions or changes to ratings criteria could continue to 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.

Recent market conditions have led to a consolidation among municipal bond insurers that may lead to a concentration of insurance company credit risk among fewer insurers.

Ohio and U.S. Territories

Because the Fund invests predominantly in Ohio municipal securities, events in Ohio are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Ohio. As with Ohio municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 12.50% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Oregon. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Oregon and U.S. Territories

Because the Fund invests predominantly in Oregon municipal securities, events in Oregon are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Oregon. As with Oregon municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 9.48% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Pennsylvania. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Pennsylvania and U.S. Territories

Because the Fund invests predominantly in Pennsylvania municipal securities, 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, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Pennsylvania. As with Pennsylvania municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Franklin Double Tax-Free Income Fund

Investment Goal

To provide investors with as high a level of income exempt from federal income taxes and from state personal income taxes, as is consistent with prudent investment management and the preservation of shareholders’ capital.

Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $100,000 in Franklin Templeton funds.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Franklin Double Tax-Free Income Fund Class C	124	387	670	1,477

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6.73% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, the Fund normally invests at least 80% of its net assets in securities whose interest is free from state personal income taxes. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund is a non-diversified fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund. The Fund focuses on the municipal securities of U.S. territories and currently primarily invests in Puerto Rican municipal securities

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Puerto Rico and U.S. Territories

Because the Fund focuses on the municipal securities of U.S. territories, and currently invests primarily in Puerto Rican municipal securities, events in Puerto Rico are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, territory constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to Puerto Rico's municipal issuers. As with Puerto Rican municipal securities, events in any of the other territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

Non-Diversification

Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting similar issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Fund’s shares and greater risk of loss.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You can obtain updated performance information at franklintempleton.com or by calling (800) DIAL BEN/342-5236.

Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class A	291	431	584	1,029
Class C	223	384	665	1,466

Franklin Federal Intermediate-Term Tax-Free Income Fund Class C	123	384	665	1,466

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6.01% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

Although the Fund does not have restrictions on the maturity of the securities it may buy, the Fund does maintain a dollar-weighted average portfolio maturity of three to 10 years.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund does not necessarily focus its investments in a particular state. The Fund may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

States and U.S. Territories

The Fund’s portfolio is generally widely diversified among issuers of municipal securities. From time to time, however, the Fund may have a significant position in the municipal securities of a particular state or territory. Under these circumstances, changes in the economic conditions in that state or territory are likely to affect the Fund’s investments and performance.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund may invest in municipal securities rated in any rating category, including defaulted securities.

The Fund does not necessarily focus its investments in a particular state and will not invest more than 25% of its total assets in municipal securities of any one state or territory. The Fund may invest up to 35% of its assets in municipal securities issued by U.S. territories.

When selecting securities for the Fund’s portfolio, the investment manager may consider existing market conditions, the availability of lower-rated securities, and whether the difference in yields between higher and lower-rated securities justifies the higher risk of lower-rated securities.

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.

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.

High-Yield Debt Securities

Issuers of lower-rated or "high-yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and 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 securities generally fluctuate more than those of higher credit quality. High-yield debt securities are generally more illiquid (harder to sell) and harder to value.

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.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class C	119	372	644	1,420

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 7.08% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its net assets in insured municipal securities. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. Generally, under normal market conditions and to the extent available, the Fund seeks to invest in insured municipal securities covered by policies issued by municipal bond insurers rated at least BBB. The Fund generally purchases bonds that have insurance in place so it does not pay insurance premiums directly. The premium costs, however, are reflected in a lower yield and/or higher price for the insured bond. When beneficial, the Fund may purchase insurance for an uninsured bond directly from a qualified municipal bond insurer, in which case the Fund pays the insurance premium directly to the insurance company. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories. The Fund will not invest more than 25% of its total assets in municipal securities of any one state or territory.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Bond Insurers

Market conditions or changes to ratings criteria could continue to 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 which meet the Fund's investment guidelines.

Recent market conditions have led to a consolidation among municipal bond insurers that may lead to a concentration of insurance company credit risk among fewer insurers.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

States and U.S. Territories

The Fund’s portfolio is generally widely diversified among issuers of municipal securities. From time to time, however, the Fund may have a significant position in the municipal securities of a particular state or territory. Under these circumstances, changes in the economic conditions in that state or territory are likely to affect the Fund’s investments and performance.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Massachusetts. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Because of its historical investment policy of investing in insured municipal securities, the Fund’s portfolio may consist to a large extent of insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. The premium costs, however, are typically reflected in a lower yield and/or higher price for the insured bond. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

Massachusetts and U.S. Territories

Because the Fund invests predominantly in Massachusetts municipal securities, events in Massachusetts are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Massachusetts. As with Massachusetts municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $100,000 in Franklin Templeton funds. More information about these and other discounts is available from your financial professional and under “Your Account” on page 101 in the Fund's Prospectus and under “Buying and Selling Shares” on page 42 of the Fund’s Statement of Additional Information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example Franklin Alabama Tax-Free Income Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Class A	494	642	803	1,270
Class C	228	400	692	1,523

If you do not sell your shares:

Franklin Alabama Tax-Free Income Fund Class C	128	400	692	1,523

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 5.35% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Alabama. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Alabama and U.S. Territories

Because the Fund invests predominantly in Alabama municipal securities, events in Alabama are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Alabama. As with Alabama municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares.

Franklin Kentucky Tax-Free Income Fund

Investment Goal

To provide investors with as high a level of income exempt from federal income taxes as is consistent with prudent investment management and the preservation of shareholders’ capital. The Fund also tries to provide a maximum level of income exempt from personal income taxes, if any, for resident shareholders of Kentucky.

Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $100,000 in Franklin Templeton funds. More information about these and other discounts is available from your financial professional and under “Your Account” on page 101 in the Fund's Prospectus and under “Buying and Selling Shares” on page 42 of the Fund’s Statement of Additional Information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Franklin Kentucky Tax-Free Income Fund Class A	498	654	824	1,316

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 17.21% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Kentucky. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Kentucky and U.S. Territories

Because the Fund invests predominantly in Kentucky municipal securities, events in Kentucky are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Kentucky. As with Kentucky municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 13.08% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its total assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Missouri. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Missouri and U.S. Territories

Because the Fund invests predominantly in Missouri municipal securities, events in Missouri are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Missouri. As with Missouri municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 13.19% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Arizona. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Arizona and U.S. Territories

Because the Fund invests predominantly in Arizona municipal securities, 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, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Arizona. As with Arizona municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance.

Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's total assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

Because of its historical investment policy of investing in insured municipal securities, the Fund’s portfolio may consist to a large extent of insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee the timely payment of principal and interest. The premium costs, however, are typically reflected in a lower yield and/or higher price for the insured bond. It is important to note that insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured.

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal. The investment manager also may consider the cost of insurance when selecting securities for the Fund.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Bond Insurers

Market conditions or changes to ratings criteria could continue to 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.

Recent market conditions have led to a consolidation among municipal bond insurers that may lead to a concentration of insurance company credit risk among fewer insurers.

Michigan and U.S. Territories

Because the Fund invests predominantly in Michigan municipal securities, 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, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Michigan. As with Michigan municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 5.32% of the average value of its portfolio.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example Franklin Oregon Tax-Free Income Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Class A	487	618	761	1,178
Class C	220	375	649	1,432
Advisor Class	54	170	296	665

If you do not sell your shares:

Franklin Oregon Tax-Free Income Fund Class C	120	375	649	1,432

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 12.50% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in securities whose interest is free from federal income taxes, including the federal alternative minimum tax. In addition, under normal market conditions, the Fund invests at least 80% of its total assets in securities that pay interest free from the personal income taxes, if any, of Oregon. Although the Fund tries to invest all of its assets in tax-free securities, it is possible that up to 20% of the Fund's net assets may be in securities that pay interest that may be subject to the federal alternative minimum tax and, although not anticipated, in securities that pay taxable interest.

The Fund only buys municipal securities rated, at the time of purchase, in one of the top four ratings categories by one or more U.S. nationally recognized rating services (or comparable unrated or short-term rated securities).

The Fund also may invest up to 35% of its total assets in municipal securities issued by U.S. territories.

Although the investment manager will search for investments across a large number of municipal securities that finance different types of projects, from time to time, based on economic conditions, the Fund may have significant positions in municipal securities that finance similar types of projects.

The investment manager selects securities that it believes will provide the best balance between risk and return within the Fund’s range of allowable investments and typically uses a buy and hold strategy. This means it generally holds securities in the Fund’s portfolio for income purposes, rather than trading securities for capital gains, although the investment manager may sell a security at any time if it believes it could help the Fund meet its goal.

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.

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. In general, securities with longer maturities are more sensitive to these interest rate changes.

Market

The market values of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security’s market value 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security'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.

Oregon and U.S. Territories

Because the Fund invests predominantly in Oregon municipal securities, events in Oregon are likely to affect the Fund's investments and its performance. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of Oregon. As with Oregon municipal securities, events in any of the territories where the Fund is invested may affect the Fund's investments and its performance.

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.

Tax-Exempt Securities

While the Fund endeavors to purchase only bona fide tax-exempt securities, there are risks that: (a) a security issued as tax-exempt may be reclassified as taxable by the Internal Revenue Service or a state tax authority, and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

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.

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.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You can obtain updated performance information at franklintempleton.com or by calling (800) DIAL BEN/342-5236.

Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.
