Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal obligations whose interest payments are excluded from gross income for federal income tax purposes and exempt from New York State and New York City personal income taxes, and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes.

The Fund may invest in municipal obligations issued by the State of New York, its political subdivisions, as well as Puerto Rico, other U.S. territories and their political subdivisions.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax, the federal alternative minimum tax on individuals or New York State and New York City personal income taxes. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

There may be times when there are not enough municipal obligations available to meet the Fund's needs. On these occasions, the Fund may invest in repurchase agreements or U.S. Treasury securities that may be subject to federal income tax.

The Fund may invest in debt securities issued by governmental entities, certain issuers identified with the U.S. government and private issuers. The Fund may invest in municipal mortgage-backed and asset-backed securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser's discretion.

The Fund may also invest in high-quality, short-term money market instruments and repurchase agreements.

The Fund may also invest in zero-coupon securities and forward commitments.

The average dollar weighted maturity of the Fund's portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund's sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/ reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Interest Rate Risk. The Fund mainly invests in bonds and other debt securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund's investments generally declines. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Geographic Concentration Risk. Because the Fund invests primarily in municipal obligations issued by the State of New York, its political subdivisions, authorities, and agencies, its performance will be affected by the fiscal and economic health of that state and its municipalities. As the nation's financial capital, New York's economy is heavily dependent on the financial sector, and may be sensitive to economic problems affecting the sector.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity.

Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments.

Credit Risk. The Fund's investments are subject to the risk that the issuer or the counterparty will fail to make payments when due or default completely. If an issuer's financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments. The Fund may invest in securities that are rated in the lowest investment grade. Issuers of such securities are more vulnerable to changes in economic conditions than issuers of higher grade securities. The Fund may invest in municipal bonds in the lowest investment grade category. Such securities are considered to have speculative characteristics similar to high yield securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Alternative Minimum Tax Risk. The Fund may invest in securities, the interest on which may be subject to the federal alternative minimum tax.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility.

Debt Securities and Other Callable Securities Risk. As part of its main investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Zero-Coupon Bond Risk. The market value of a zero-coupon bond is generally more volatile than the market value of other fixed income securities with similar maturities that pay interest periodically.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund's Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Barclays New York Competitive Intermediate (1–17 Year) Maturities Index and the Lipper Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund's designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares shown in the table is based on the performance of Class B Shares prior to the inception of the Class C Shares. The actual returns of Class C Shares would have been similar to those shown because the classes have similar expenses. 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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal securities, the income from which is exempt from federal and state personal income taxes for California residents and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes. The Fund seeks investments that also provide high current income. Municipal securities in which the Fund can invest include those issued by the State of California, its political subdivisions, as well as Puerto Rico, other U.S. territories and their political subdivisions. Because the Fund's objective is high after-tax total return rather than high tax-exempt income, the Fund may invest to a limited extent in securities of other states or territories. To the extent that the Fund invests in municipal securities of other states, the income from such securities would be free from federal personal income taxes for California residents but would be subject to California taxes. For non-California residents, the income from California municipal securities may also be subject to state and local taxes in their jurisdiction of residence.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax, the federal alternative minimum tax on individuals or California personal income taxes. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

The Fund's securities may be of any maturity, but under normal circumstances the Fund's duration will generally range between three and seven years, similar to that of the Barclays LB California 1-17 Year Muni Index. Duration is a measure of the price sensitivity of a debt security or a portfolio of debt securities to relative changes in interest rates. For instance, a duration of "three" means that a security's or portfolio's price would be expected to decrease by approximately 3% with a 1% increase in interest rates (assuming a parallel shift in yield curve). As of May 31, 2013, the duration of the Barclays LB California 1-17 Year Muni Index was 5.12 years, although the duration will likely vary in the future.

There may be times when there are not enough municipal securities available to meet the Fund's needs. On these occasions, the Fund may invest in securities that may be subject to federal income tax.

The Fund may invest in debt securities issued by governmental entities, certain issuers identified with the U.S. government and private issuers. The Fund may invest in municipal mortgage-backed and asset-backed securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser's discretion.

The Fund may also invest in high-quality, short-term money market instruments and repurchase agreements.

The Fund may also invest in zero-coupon securities.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/ reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Interest Rate Risk. The Fund mainly invests in bonds and other debt securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund's investments generally declines. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Geographic Concentration Risk. Because the Fund primarily invests in issuers in the State of California, its performance will be affected by the fiscal and economic health of that state and its municipalities. Provisions of the California Constitution and state statutes that limit the taxing and spending authority of California's governmental entities may impair the ability of California issuers to pay principal and/or interest on their obligations. While California's economy is broad, it does have major concentrations in high technology, manufacturing, entertainment, agriculture, tourism, construction and services, and may be sensitive to economic problems affecting those industries.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity.

Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments.

Credit Risk. The Fund's investments are subject to the risk that the issuer or the counterparty will fail to make payments when due or default completely. If an issuer's financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments. The Fund may invest in securities that are rated in the lowest investment grade. Issuers of such securities are more vulnerable to changes in economic conditions than issuers of higher grade securities. The Fund may invest in municipal bonds in the lowest investment grade category. Such securities are considered to have speculative characteristics similar to high yield securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Alternative Minimum Tax Risk. The Fund may invest in securities, the interest on which may be subject to the federal alternative minimum tax.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility.

Debt Securities and Other Callable Securities Risk. As part of its main investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Zero-Coupon Bond Risk. The market value of a zero-coupon bond is generally more volatile than the market value of other fixed income securities with similar maturities that pay interest periodically.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Barclays LB California 1-17 Year Muni Index (formerly known as the Barclays California Competitive Intermediate Municipal Bond (1-17 Year) Index) and the Lipper California Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares shown in the table is based on the performance of Class A Shares prior to the inception of the Class C Shares. The actual returns of Class C Shares would have been lower than those shown because Class C Shares have higher expenses than the Class A Shares on which their performance is based. 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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal securities, the income from which is exempt from federal and state personal income taxes for California residents and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes. The Fund seeks investments that also provide high current income. Municipal securities in which the Fund can invest include those issued by the State of California, its political subdivisions, as well as Puerto Rico, other U.S. territories and their political subdivisions. Because the Fund's objective is high after-tax total return rather than high tax-exempt income, the Fund may invest to a limited extent in securities of other states or territories. To the extent that the Fund invests in municipal securities of other states, the income from such securities would be free from federal personal income taxes for California residents but would be subject to California taxes. For non-California residents, the income from California municipal securities may also be subject to state and local taxes in their jurisdiction of residence.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax, the federal alternative minimum tax on individuals or California personal income taxes. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

The Fund's securities may be of any maturity, but under normal circumstances the Fund's duration will generally range between three and seven years, similar to that of the Barclays LB California 1-17 Year Muni Index. Duration is a measure of the price sensitivity of a debt security or a portfolio of debt securities to relative changes in interest rates. For instance, a duration of "three" means that a security's or portfolio's price would be expected to decrease by approximately 3% with a 1% increase in interest rates (assuming a parallel shift in yield curve). As of May 31, 2013, the duration of the Barclays LB California 1-17 Year Muni Index was 5.12 years, although the duration will likely vary in the future.

There may be times when there are not enough municipal securities available to meet the Fund's needs. On these occasions, the Fund may invest in securities that may be subject to federal income tax.

The Fund may invest in debt securities issued by governmental entities, certain issuers identified with the U.S. government and private issuers. The Fund may invest in municipal mortgage-backed and asset-backed securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser's discretion.

The Fund may also invest in high-quality, short-term money market instruments and repurchase agreements.

The Fund may also invest in zero-coupon securities.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/ reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Interest Rate Risk. The Fund mainly invests in bonds and other debt securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund's investments generally declines. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Geographic Concentration Risk. Because the Fund primarily invests in issuers in the State of California, its performance will be affected by the fiscal and economic health of that state and its municipalities. Provisions of the California Constitution and state statutes that limit the taxing and spending authority of California's governmental entities may impair the ability of California issuers to pay principal and/or interest on their obligations. While California's economy is broad, it does have major concentrations in high technology, manufacturing, entertainment, agriculture, tourism, construction and services, and may be sensitive to economic problems affecting those industries.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity.

Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments.

Credit Risk. The Fund's investments are subject to the risk that the issuer or the counterparty will fail to make payments when due or default completely. If an issuer's financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments. The Fund may invest in securities that are rated in the lowest investment grade. Issuers of such securities are more vulnerable to changes in economic conditions than issuers of higher grade securities. The Fund may invest in municipal bonds in the lowest investment grade category. Such securities are considered to have speculative characteristics similar to high yield securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Alternative Minimum Tax Risk. The Fund may invest in securities, the interest on which may be subject to the federal alternative minimum tax.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility.

Debt Securities and Other Callable Securities Risk. As part of its main investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Zero-Coupon Bond Risk. The market value of a zero-coupon bond is generally more volatile than the market value of other fixed income securities with similar maturities that pay interest periodically.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

What are the Fund’s main investment strategies?

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal securities, the income from which is exempt from federal and state personal income taxes for California residents and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes. The Fund seeks investments that also provide high current income. Municipal securities in which the Fund can invest include those issued by the State of California, its political subdivisions, as well as Puerto Rico, other U.S. territories and their political subdivisions. Because the Fund's objective is high after-tax total return rather than high tax-exempt income, the Fund may invest to a limited extent in securities of other states or territories. To the extent that the Fund invests in municipal securities of other states, the income from such securities would be free from federal personal income taxes for California residents but would be subject to California taxes. For non-California residents, the income from California municipal securities may also be subject to state and local taxes in their jurisdiction of residence.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax, the federal alternative minimum tax on individuals or California personal income taxes. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

The Fund's securities may be of any maturity, but under normal circumstances the Fund's duration will generally range between three and seven years, similar to that of the Barclays LB California 1-17 Year Muni Index. Duration is a measure of the price sensitivity of a debt security or a portfolio of debt securities to relative changes in interest rates. For instance, a duration of "three" means that a security's or portfolio's price would be expected to decrease by approximately 3% with a 1% increase in interest rates (assuming a parallel shift in yield curve). As of May 31, 2013, the duration of the Barclays LB California 1-17 Year Muni Index was 5.12 years, although the duration will likely vary in the future.

There may be times when there are not enough municipal securities available to meet the Fund's needs. On these occasions, the Fund may invest in securities that may be subject to federal income tax.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Interest Rate Risk. The Fund mainly invests in bonds and other debt securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund's investments generally declines. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Geographic Concentration Risk. Because the Fund primarily invests in issuers in the State of California, its performance will be affected by the fiscal and economic health of that state and its municipalities. Provisions of the California Constitution and state statutes that limit the taxing and spending authority of California's governmental entities may impair the ability of California issuers to pay principal and/or interest on their obligations. While California's economy is broad, it does have major concentrations in high technology, manufacturing, entertainment, agriculture, tourism, construction and services, and may be sensitive to economic problems affecting those industries.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity.

Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments.

Credit Risk. The Fund's investments are subject to the risk that the issuer or the counterparty will fail to make payments when due or default completely. If an issuer's financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments. The Fund may invest in securities that are rated in the lowest investment grade. Issuers of such securities are more vulnerable to changes in economic conditions than issuers of higher grade securities. The Fund may invest in municipal bonds in the lowest investment grade category. Such securities are considered to have speculative characteristics similar to high yield securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Alternative Minimum Tax Risk. The Fund may invest in securities, the interest on which may be subject to the federal alternative minimum tax.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility.

Debt Securities and Other Callable Securities Risk. As part of its main investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Zero-Coupon Bond Risk. The market value of a zero-coupon bond is generally more volatile than the market value of other fixed income securities with similar maturities that pay interest periodically.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Barclays LB California 1-17 Year Muni Index (formerly known as the Barclays California Competitive Intermediate Municipal Bond (1-17 Year) Index) and the Lipper California Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares shown in the table is based on the performance of Class A Shares prior to the inception of the Class C Shares. The actual returns of Class C Shares would have been lower than those shown because Class C Shares have higher expenses than the Class A Shares on which their performance is based. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal obligations whose interest payments are excluded from gross income for federal income tax purposes and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax or the federal alternative minimum tax on individuals. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

There may be times when there are not enough municipal obligations available to meet the Fund's needs. On these occasions, the Fund may invest in repurchase agreements or U.S. Treasury securities that may be subject to federal income tax.

The Fund may invest in debt securities issued by governmental entities, certain issuers identified with the U.S. government and private issuers. The Fund may invest in municipal mortgage-backed and asset-backed securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser's discretion.

The Fund may also invest in high-quality, short-term money market instruments and repurchase agreements.

The Fund may also invest in zero-coupon securities and forward commitments.

The average dollar weighted maturity of the Fund's portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund's sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/ reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Interest Rate Risk. The Fund mainly invests in bonds and other debt securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund's investments generally declines. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity.

Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments.

Credit Risk. The Fund's investments are subject to the risk that the issuer or the counterparty will fail to make payments when due or default completely. If an issuer's financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments. The Fund may invest in securities that are rated in the lowest investment grade. Issuers of such securities are more vulnerable to changes in economic conditions than issuers of higher grade securities. The Fund may invest in municipal bonds in the lowest investment grade category. Such securities are considered to have speculative characteristics similar to high yield securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Alternative Minimum Tax Risk. The Fund may invest in securities, the interest on which may be subject to the federal alternative minimum tax.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility.

Debt Securities and Other Callable Securities Risk. As part of its main investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities.

The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

What are the Fund’s main investment strategies?

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal obligations whose interest payments are excluded from gross income for federal income tax purposes and exempt from New York State and New York City personal income taxes, and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes.

The Fund may invest in municipal obligations issued by the State of New York, its political subdivisions, as well as Puerto Rico, other U.S. territories and their political subdivisions.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax, the federal alternative minimum tax on individuals or New York State and New York City personal income taxes. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

There may be times when there are not enough municipal obligations available to meet the Fund's needs. On these occasions, the Fund may invest in repurchase agreements or U.S. Treasury securities that may be subject to federal income tax.

The Fund may invest in debt securities issued by governmental entities, certain issuers identified with the U.S. government and private issuers. The Fund may invest in municipal mortgage-backed and asset-backed securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser's discretion.

The Fund may also invest in high-quality, short-term money market instruments and repurchase agreements.

The Fund may also invest in zero-coupon securities and forward commitments.

The average dollar weighted maturity of the Fund's portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund's sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/ reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Interest Rate Risk. The Fund mainly invests in bonds and other debt securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund's investments generally declines. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Geographic Concentration Risk. Because the Fund invests primarily in municipal obligations issued by the State of New York, its political subdivisions, authorities, and agencies, its performance will be affected by the fiscal and economic health of that state and its municipalities. As the nation's financial capital, New York's economy is heavily dependent on the financial sector, and may be sensitive to economic problems affecting the sector.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity.

Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments.

Credit Risk. The Fund's investments are subject to the risk that the issuer or the counterparty will fail to make payments when due or default completely. If an issuer's financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments. The Fund may invest in securities that are rated in the lowest investment grade. Issuers of such securities are more vulnerable to changes in economic conditions than issuers of higher grade securities. The Fund may invest in municipal bonds in the lowest investment grade category. Such securities are considered to have speculative characteristics similar to high yield securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Alternative Minimum Tax Risk. The Fund may invest in securities, the interest on which may be subject to the federal alternative minimum tax.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility.

Debt Securities and Other Callable Securities Risk. As part of its main investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Zero-Coupon Bond Risk. The market value of a zero-coupon bond is generally more volatile than the market value of other fixed income securities with similar maturities that pay interest periodically.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund's Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Barclays New York Competitive Intermediate (1–17 Year) Maturities Index and the Lipper Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund's designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares shown in the table is based on the performance of Class B Shares prior to the inception of the Class C Shares. The actual returns of Class C Shares would have been similar to those shown because the classes have similar expenses. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

What are the Fund’s main investment strategies?

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal securities, the income from which is exempt from federal and state personal income taxes for California residents and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes. The Fund seeks investments that also provide high current income. Municipal securities in which the Fund can invest include those issued by the State of California, its political subdivisions, as well as Puerto Rico, other U.S. territories and their political subdivisions. Because the Fund's objective is high after-tax total return rather than high tax-exempt income, the Fund may invest to a limited extent in securities of other states or territories. To the extent that the Fund invests in municipal securities of other states, the income from such securities would be free from federal personal income taxes for California residents but would be subject to California taxes. For non-California residents, the income from California municipal securities may also be subject to state and local taxes in their jurisdiction of residence.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax, the federal alternative minimum tax on individuals or California personal income taxes. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

The Fund's securities may be of any maturity, but under normal circumstances the Fund's duration will generally range between three and seven years, similar to that of the Barclays LB California 1-17 Year Muni Index. Duration is a measure of the price sensitivity of a debt security or a portfolio of debt securities to relative changes in interest rates. For instance, a duration of "three" means that a security's or portfolio's price would be expected to decrease by approximately 3% with a 1% increase in interest rates (assuming a parallel shift in yield curve). As of May 31, 2013, the duration of the Barclays LB California 1-17 Year Muni Index was 5.12 years, although the duration will likely vary in the future.

There may be times when there are not enough municipal securities available to meet the Fund's needs. On these occasions, the Fund may invest in securities that may be subject to federal income tax.

The Fund may invest in debt securities issued by governmental entities, certain issuers identified with the U.S. government and private issuers. The Fund may invest in municipal mortgage-backed and asset-backed securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser's discretion.

The Fund may also invest in high-quality, short-term money market instruments and repurchase agreements.

The Fund may also invest in zero-coupon securities.

Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/ reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Interest Rate Risk. The Fund mainly invests in bonds and other debt securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund's investments generally declines. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Geographic Concentration Risk. Because the Fund primarily invests in issuers in the State of California, its performance will be affected by the fiscal and economic health of that state and its municipalities. Provisions of the California Constitution and state statutes that limit the taxing and spending authority of California's governmental entities may impair the ability of California issuers to pay principal and/or interest on their obligations. While California's economy is broad, it does have major concentrations in high technology, manufacturing, entertainment, agriculture, tourism, construction and services, and may be sensitive to economic problems affecting those industries.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity.

Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments.

Credit Risk. The Fund's investments are subject to the risk that the issuer or the counterparty will fail to make payments when due or default completely. If an issuer's financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments. The Fund may invest in securities that are rated in the lowest investment grade. Issuers of such securities are more vulnerable to changes in economic conditions than issuers of higher grade securities. The Fund may invest in municipal bonds in the lowest investment grade category. Such securities are considered to have speculative characteristics similar to high yield securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Alternative Minimum Tax Risk. The Fund may invest in securities, the interest on which may be subject to the federal alternative minimum tax.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility.

Debt Securities and Other Callable Securities Risk. As part of its main investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Zero-Coupon Bond Risk. The market value of a zero-coupon bond is generally more volatile than the market value of other fixed income securities with similar maturities that pay interest periodically.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 6/30/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

Expense Example, No Redemption A, B, C, Select Shares JPMorgan Intermediate Tax Free Bond Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	450	642	850	1,450
CLASS B SHARES	145	449	776	1,566
CLASS C SHARES	145	449	776	1,702
SELECT CLASS SHARES	61	207	366	828

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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 14% of the average value of its portfolio.

What are the Fund’s main investment strategies?

As a fundamental policy, the Fund normally invests at least 80% of the value of its Assets in municipal obligations whose interest payments are excluded from gross income for federal income tax purposes and not subject to the federal alternative minimum tax on individuals. "Assets" means net assets, plus the amount of borrowings for investment purposes.

Under normal circumstances, the Fund reserves the right to invest up to 20% of its Assets in securities that pay interest subject to federal income tax or the federal alternative minimum tax on individuals. To defend the value of its assets during unusual market conditions, the Fund may temporarily exceed this limit.

There may be times when there are not enough municipal obligations available to meet the Fund's needs. On these occasions, the Fund may invest in repurchase agreements or U.S. Treasury securities that may be subject to federal income tax.

The Fund may invest in debt securities issued by governmental entities, certain issuers identified with the U.S. government and private issuers. The Fund may invest in municipal mortgage-backed and asset-backed securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser's discretion.

The Fund may also invest in high-quality, short-term money market instruments and repurchase agreements.

The Fund may also invest in zero-coupon securities and forward commitments.

The average dollar weighted maturity of the Fund's portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund's sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/ reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows the performance of the Fund’s Select Class Shares over the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Barclays U.S. 1-15 Year Blend ( 1-17) Municipal Bond Index (formerly known as the Barclays Competitive Intermediate (1-17 Year) Maturities Index) and the Lipper Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class A, Class B and Class C Shares shown in the table is based on the performance of Select Class Shares prior to their inception. The actual returns of the Class A, Class B and Class C Shares would have been lower than those shown because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.
