  <rr:RiskNarrativeTextBlock contextRef="Duration_29Sep2011_28Sep2012S000000596_Member">&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The price and yield of this Fund will change daily, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include: &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Alternative Minimum Tax Risk&lt;/b&gt;&amp;#8212;The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund&amp;#8217;s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Call Risk&lt;/b&gt;&amp;#8212;If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Credit Risk&lt;/b&gt;&amp;#8212;Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer&amp;#8217;s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Also, the Fund&amp;#8217;s investments in inverse floaters will increase the Fund&amp;#8217;s credit risk. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;High Yield Securities Risk&lt;/b&gt;&amp;#8212;High yield securities are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid, and have more volatile prices than investment grade securities. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Income Risk&lt;/b&gt;&amp;#8212;The Fund&amp;#8217;s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund&amp;#8217;s income may decrease if short-term interest rates rise. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Interest Rate Risk&lt;/b&gt;&amp;#8212;Interest rate risk is the risk that the value of the Fund&amp;#8217;s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund&amp;#8217;s investment in inverse floaters because of the leveraged nature of these investments. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Inverse Floaters Risk&lt;/b&gt;&amp;#8212;The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Market Risk&lt;/b&gt;&amp;#8212;The market values of the Fund&amp;#8217;s investments may decline, at times sharply and unpredictably. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Municipal Lease Obligations Risk&lt;/b&gt;&amp;#8212;Participation interests in municipal leases pose special risks because many leases and contracts contain &amp;#8220;non-appropriation&amp;#8221; clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Non-Diversification Risk&lt;/b&gt;&amp;#8212;As a non-diversified fund, the Fund may invest a larger portion of its assets in the securities of a limited number of issuers and may be more sensitive to any single economic, political or regulatory occurrence than a diversified fund. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Political and Economic Risks&lt;/b&gt;&amp;#8212;The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Because the Fund primarily purchases municipal bonds from Kansas, the Fund is more susceptible to adverse economic, political or regulatory changes affecting municipal bond issuers in that state. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Tax Risk&lt;/b&gt;&amp;#8212;Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Zero Coupon Bonds Risk&lt;/b&gt;&amp;#8212;Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws. &lt;/font&gt;</rr:RiskNarrativeTextBlock>

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include: &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Alternative Minimum Tax Risk&lt;/b&gt;&amp;#8212;The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund&amp;#8217;s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Call Risk&lt;/b&gt;&amp;#8212;If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Credit Risk&lt;/b&gt;&amp;#8212;Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer&amp;#8217;s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Also, the Fund&amp;#8217;s investments in inverse floaters will increase the Fund&amp;#8217;s credit risk. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;High Yield Securities Risk&lt;/b&gt;&amp;#8212;High yield securities are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid, and have more volatile prices than investment grade securities. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Income Risk&lt;/b&gt;&amp;#8212;The Fund&amp;#8217;s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund&amp;#8217;s income may decrease if short-term interest rates rise. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Interest Rate Risk&lt;/b&gt;&amp;#8212;Interest rate risk is the risk that the value of the Fund&amp;#8217;s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund&amp;#8217;s investment in inverse floaters because of the leveraged nature of these investments. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Inverse Floaters Risk&lt;/b&gt;&amp;#8212;The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Market Risk&lt;/b&gt;&amp;#8212;The market values of the Fund&amp;#8217;s investments may decline, at times sharply and unpredictably. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Municipal Lease Obligations Risk&lt;/b&gt;&amp;#8212;Participation interests in municipal leases pose special risks because many leases and contracts contain &amp;#8220;non-appropriation&amp;#8221; clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Political and Economic Risks&lt;/b&gt;&amp;#8212;The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Because the Fund primarily purchases municipal bonds from Kentucky, the Fund is more susceptible to adverse economic, political or regulatory changes affecting municipal bond issuers in that state.&lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Tax Risk&lt;/b&gt;&amp;#8212;Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;&lt;b&gt;Zero Coupon Bonds Risk&lt;/b&gt;&amp;#8212;Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws. &lt;/font&gt;</rr:RiskNarrativeTextBlock>

Interest rate risk may be increased by the Fund&amp;#8217;s investment in inverse floaters because of the leveraged nature of these investments.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Inverse Floaters Risk&lt;/b&gt;&amp;#8212;The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk&lt;/b&gt;&amp;#8212;The market values of the Fund&amp;#8217;s investments may decline, at times sharply and unpredictably.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Municipal Lease Obligations Risk&lt;/b&gt;&amp;#8212;Participation interests in municipal leases pose special risks because many leases and contracts contain &amp;#8220;non-appropriation&amp;#8221; clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Political and Economic Risks&lt;/b&gt;&amp;#8212;The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Because the Fund primarily purchases municipal bonds from Missouri, the Fund is more susceptible to adverse economic, political or regulatory changes affecting municipal bond issuers in that state.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Tax Risk&lt;/b&gt;&amp;#8212;Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Zero Coupon Bonds Risk&lt;/b&gt;&amp;#8212;Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws. &lt;/font&gt;</rr:RiskNarrativeTextBlock>

The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund will generally maintain, under normal market conditions, an investment portfolio with an overall weighted average maturity in excess of 10 years. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund&amp;#8217;s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as &amp;#8220;high yield&amp;#8221; or &amp;#8220;junk&amp;#8221; bonds. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (&lt;i&gt;&amp;#8220;inverse floaters&amp;#8221;&lt;/i&gt;). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund&amp;#8217;s investments in inverse floaters are designed to increase the Fund&amp;#8217;s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund&amp;#8217;s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued long-term municipal bonds that offer above-average total return.

The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund will generally maintain, under normal market conditions, an investment portfolio with an overall weighted average maturity in excess of 10 years. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt; &lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund&amp;#8217;s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as &amp;#8220;high yield&amp;#8221; or &amp;#8220;junk&amp;#8221; bonds. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt; &lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt; &lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (&lt;i&gt;&amp;#8220;inverse floaters&amp;#8221;&lt;/i&gt;). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund&amp;#8217;s investments in inverse floaters are designed to increase the Fund&amp;#8217;s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt; &lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund&amp;#8217;s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued long-term municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds. &lt;/font&gt;</rr:StrategyNarrativeTextBlock>

The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund will generally maintain, under normal market conditions, an investment portfolio with an overall weighted average maturity in excess of 10 years. &lt;/font&gt;&lt;br /&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund&amp;#8217;s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as &amp;#8220;high yield&amp;#8221; or &amp;#8220;junk&amp;#8221; bonds. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (&lt;i&gt;&amp;#8220;inverse floaters&amp;#8221;&lt;/i&gt;). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund&amp;#8217;s investments in inverse floaters are designed to increase the Fund&amp;#8217;s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The Fund&amp;#8217;s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued long-term municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds. &lt;/font&gt;</rr:StrategyNarrativeTextBlock>
