Example: <div style="line-height: 10.695pt; text-align: left;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">or lower, based on these assumptions your costs would be:</span><span style="color: #000000; font-family: arial; font-size: 1pt; line-height: 0.93pt;"> </span></div> 506 710 930 1562 261 535 933 1845 59 227 409 936 You would pay the following expenses if you did not redeem your shares:  161 535 933 1845 Portfolio Turnover: <div style="line-height: 10.695pt; text-align: left;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">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 shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio. </span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> 0.16 Principal Investment Strategies of the Fund <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund invests primarily in a portfolio of long-term investment grade New Jersey municipal bonds. New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in New Jersey municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. When choosing investments, Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be more than ten years. </span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s 80% policy. </span></div> New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam.

Changes in an issuer’s credit rating or the market’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Interest Rate Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — The market value of bonds and other fixed-income securities changes in response to interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%. (Duration is a measure of the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities with longer maturities.

Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">28</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">% of the average value of its portfolio.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> 0.28 Principal Investment Strategies of the Fund <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund invests primarily in a portfolio of long-term investment grade Pennsylvania municipal bonds. Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes. These may be obligations of a variety of issuers including governmental entities in Pennsylvania and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in Pennsylvania municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. When choosing investments, Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be more than ten years. </span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s 80% policy. </span></div> Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes. These may be obligations of a variety of issuers including governmental entities in Pennsylvania and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in Pennsylvania municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. <div> <div style="clear: both; margin-top: 4.805pt; position: relative; width: 100%;"> <div style="float: left; line-height: 9.87pt; text-align: left; width: 8pt;"><span style="color: #000000; font-family: arial; font-size: 8.37pt; position: relative; top: -0.5pt;">◼</span></div> <div style="float: left; line-height: 10.80pt; margin-left: 4pt; text-align: left; width: 505.00pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic; font-weight: bold;">Debt Securities Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — Debt securities, such as bonds, involve risks, such as credit risk, interest rate risk, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">extension risk, and prepayment risk, each of which are described in further detail below:</span></div> </div> <div style="clear: both; position: relative;"> </div> </div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Credit Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — Credit risk refers to the possibility that the issuer of a debt security (i.e., the borrower) will not be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Interest Rate Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — The market value of bonds and other fixed-income securities changes in response to interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%. (Duration is a measure of the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">income derived from instruments already owned by the Fund, but will be reflected in the Fund’s net asset value. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">management.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities. A security backed by the “full faith </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">and credit” of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">value when interest rates change.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">hurt the Fund’s performance.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Extension Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — When interest rates rise, certain obligations will be paid off by the obligor more slowly than </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">anticipated, causing the value of these obligations to fall.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Prepayment Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — When interest rates fall, certain obligations will be paid off by the obligor more quickly than </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div> <div style="clear: both; margin-top: 4.805pt; position: relative; width: 100%;"> <div style="float: left; line-height: 9.87pt; text-align: left; width: 8pt;"><span style="color: #000000; font-family: arial; font-size: 8.37pt; position: relative; top: -0.5pt;">◼</span></div> <div style="float: left; line-height: 10.80pt; margin-left: 4pt; text-align: left; width: 505.00pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic; font-weight: bold;">Municipal Securities Risks </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">— Municipal securities risks include the ability of the issuer to repay the obligation, the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">relative lack of information about certain issuers of municipal securities, and the possibility of future legislative </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">changes which could affect the market for and value of municipal securities.

Distributions on TOB Residuals </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">fixed rate municipal securities in a rising interest rate environment. The Fund may invest in TOB Trusts on either a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">non-recourse or recourse basis.

New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in New Jersey municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. When choosing investments, Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be more than ten years. </span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">80% policy.</span></div> New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in New Jersey municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities.

Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%.

The magnitude </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities with longer maturities.

Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">28</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">% of the average value of its portfolio.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> 0.28 Principal Investment Strategies of the Fund <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund invests primarily in a portfolio of long-term investment grade Pennsylvania municipal bonds. Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes. These may be obligations of a variety of issuers including governmental entities in Pennsylvania and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in Pennsylvania municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. When choosing investments, Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be more than ten years. </span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s 80% policy. </span></div> Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes.

Changes in an issuer’s credit rating or the market’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Interest Rate Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — The market value of bonds and other fixed-income securities changes in response to interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%. (Duration is a measure of the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest </span></div> <div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">income derived from instruments already owned by the Fund, but will be reflected in the Fund’s net asset value. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">management.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities. A security backed by the “full faith </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">and credit” of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">value when interest rates change.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">scale, which may increase redemptions from funds that hold large amounts of fixed-income securities.

Distributions on TOB Residuals </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">fixed rate municipal securities in a rising interest rate environment. The Fund may invest in TOB Trusts on either a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">non-recourse or recourse basis.

New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in New Jersey municipal bonds. For the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">extent that they provide investment exposure to the securities included within that policy or to one or more market risk </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities. Investment grade securities are securities which are rated in the four highest categories by at least one of </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">the major rating agencies or determined by the management team to be of similar quality. When choosing investments, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">more than ten years.</span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">80% policy.</span></div> New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in New Jersey municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities.

Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%. (Duration is a measure of the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">income derived from instruments already owned by the Fund, but will be reflected in the Fund’s net asset value. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">management.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Example, affect the Fund’s performance.

Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes. These may be obligations of a variety of issuers including governmental entities in Pennsylvania and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in Pennsylvania municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. When choosing investments, Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be more than ten years. </span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">80% policy.</span></div> Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes.

Changes in an issuer’s credit rating or the market’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.</span></div> <div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Interest Rate Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — The market value of bonds and other fixed-income securities changes in response to interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%. (Duration is a measure of the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">income derived from instruments already owned by the Fund, but will be reflected in the Fund’s net asset value. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">management.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities. A security backed by the “full faith </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">and credit” of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">value when interest rates change.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">scale, which may increase redemptions from funds that hold large amounts of fixed-income securities.

Distributions on TOB Residuals </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">fixed rate municipal securities in a rising interest rate environment. The Fund may invest in TOB Trusts on either a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">non-recourse or recourse basis.

New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in New Jersey municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. When choosing investments, Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be more than ten years.</span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">80% policy.</span></div> New Jersey municipal bonds are debt obligations issued by or on behalf of a governmental entity in New Jersey or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from New Jersey personal income taxes. These bonds may be obligations of a variety of issuers including governmental entities in New Jersey and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in New Jersey municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities.

Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%.

Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities.

The performance information for periods prior to January 25, 2018, the commencement of operations of Class K Shares, shows the performance of the Fund’s Institutional Shares. The performance of the Fund’s Class K Shares would be substantially similar to Institutional Shares because Class K Shares and Institutional Shares invest in the same portfolio of securities and performance would only differ to the extent that Class K Shares and Institutional Shares have different expenses. The actual returns of Class K Shares would have been higher than those of the Institutional Shares because Class K Shares have lower expenses than the Institutional Shares. The table compares the Fund’s performance to that of the Bloomberg Municipal Bond Index and a customized weighted index comprised of 90% Bloomberg Municipal Bond: New Jersey Exempt Total Return Index Unhedged USD and 10% New Jersey Bloomberg Municipal Bond: High Yield (non-Investment Grade) Total Return Index (the “New Jersey Customized Reference Benchmark”). The New Jersey Customized Reference Benchmark is relevant to the Fund because it has characteristics similar to the Fund’s investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information for the Fund in the chart and table assumes reinvestment of the dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. The table includes all applicable fees. If the Fund’s investment manager and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund’s returns would have been lower.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">28</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">% of the average value of its portfolio.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> 0.28 Principal Investment Strategies of the Fund <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund invests primarily in a portfolio of long-term investment grade Pennsylvania municipal bonds. Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes. These may be obligations of a variety of issuers including governmental entities in Pennsylvania and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam. Under normal circumstances, the Fund will invest at least 80% of its assets in Pennsylvania municipal bonds. For the purposes of the foregoing 80% policy, “assets” are the Fund’s net assets, plus the amount of any borrowings for investment purposes. The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. At least 80% of the Fund’s assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. When choosing investments, Fund management considers various factors, including the credit quality of issuers, yield analysis, maturity analysis and the call features of the obligations. Under normal circumstances, the Fund’s weighted average maturity will be more than ten years.</span></div> <div style="margin-top: 6pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">purpose entity (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">interests (“TOB Floaters”), which are sold to third party investors, and residual inverse floating rate interests (“TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Residuals”), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Fund’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">80% policy.</span></div> Pennsylvania municipal bonds are debt obligations issued by or on behalf of a governmental entity in Pennsylvania or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from Pennsylvania personal income taxes. These may be obligations of a variety of issuers including governmental entities in Pennsylvania and issuers located in Puerto Rico, the U.S. Virgin Islands and Guam.

The Fund’s investments in derivatives will be counted toward the foregoing 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. <div> <div style="clear: both; margin-top: 4.805pt; position: relative; width: 100%;"> <div style="float: left; line-height: 9.87pt; text-align: left; width: 8pt;"><span style="color: #000000; font-family: arial; font-size: 8.37pt; position: relative; top: -0.5pt;">◼</span></div> <div style="float: left; line-height: 10.80pt; margin-left: 4pt; text-align: left; width: 505.00pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic; font-weight: bold;">Debt Securities Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — Debt securities, such as bonds, involve risks, such as credit risk, interest rate risk, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">extension risk, and prepayment risk, each of which are described in further detail below:</span></div> </div> <div style="clear: both; position: relative;"> </div> </div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Credit Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — Credit risk refers to the possibility that the issuer of a debt security (i.e., the borrower) will not be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;">Interest Rate Risk</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> — The market value of bonds and other fixed-income securities changes in response to interest </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will increase as interest rates fall and decrease as interest rates rise.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">equal, the value of the Fund’s investments would be expected to decrease by 10%. (Duration is a measure of the </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest </span></div> <div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">income derived from instruments already owned by the Fund, but will be reflected in the Fund’s net asset value. The </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">management.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed</span><span style="color: #000000; font-family: arial; font-size: 9.30pt;"> securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">debt securities.</span><span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"> </span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">These basic principles of bond prices also apply to U.S. Government securities. A security backed by the “full faith </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">and credit” of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">value when interest rates change.</span></div> <div style="margin-top: 4pt;"><span style="color: #000000; font-family: arial; font-size: 9.30pt;">A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">scale, which may increase redemptions from funds that hold large amounts of fixed-income securities.

Investments in tender option bond transactions expose the Fund to counterparty </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">risk and leverage risk.

Distributions on TOB Residuals </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">fixed rate municipal securities in a rising interest rate environment. The Fund may invest in TOB Trusts on either a </span><span style="color: #000000; font-family: arial; font-size: 9.30pt;">non-recourse or recourse basis.

The performance information for periods prior to January 25, 2018, the commencement of operations of Class K Shares, shows the performance of the Fund’s Institutional Shares. The performance of the Fund’s Class K Shares would be substantially similar to Institutional Shares because Class K Shares and Institutional Shares invest in the same portfolio of securities and performance would only differ to the extent that Class K Shares and Institutional Shares have different expenses. The actual returns of Class K Shares would have been higher than those of the Institutional Shares because Class K Shares have lower expenses than the Institutional Shares. The table compares the Fund’s performance to that of the Bloomberg Municipal Bond Index and a customized weighted index comprised of 90% Bloomberg Pennsylvania Total Return Index Unhedged USD and 10% Pennsylvania Bloomberg Municipal Bond: High Yield (non-Investment Grade) Total Return Index (the “Pennsylvania Customized Reference Benchmark”). The Pennsylvania Customized Reference Benchmark is relevant to the Fund because it has characteristics similar to the Fund’s investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information for the Fund in the chart and table assumes reinvestment of the dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. The table includes all applicable fees. If the Fund’s investment manager and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund’s returns would have been lower.
