High-quality, long-term Ohio municipal&lt;br /&gt;obligations are, for purposes of this Fund, considered to be obligations rated&lt;br /&gt;within the three highest rating categories, with remaining maturities of 3 years&lt;br /&gt;or more. This is a non-fundamental investment policy and the Fund will provide&lt;br /&gt;shareholders with at least 60 days&apos; prior notice of any change in this policy.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;The Fund invests primarily in Ohio municipal obligations rated within the three&lt;br /&gt;highest rating categories. The Fund may also purchase Ohio municipal obligations &lt;br /&gt;and other securities rated within the four highest rating categories. If a &lt;br /&gt;security&apos;s rating is reduced below the four highest rating categories, the security &lt;br /&gt;will be sold. A security may also be sold due to changes in market conditions or &lt;br /&gt;Fort Washington Investment Advisors, Inc.&apos;s ("Fort Washington" or the "Sub-Advisor") &lt;br /&gt;outlook. The Fund may purchase unrated obligations that the Sub-Advisor determines &lt;br /&gt;to be of comparable quality. The Fund has a fundamental investment policy that under &lt;br /&gt;normal circumstances at least 80% of the income it distributes will be exempt from &lt;br /&gt;federal income tax, including the alternative minimum tax, and Ohio personal income &lt;br /&gt;tax. This fundamental policy may not be changed without the approval of the Fund&apos;s&lt;br /&gt;shareholders. The Fund will seek to maintain an average weighted maturity of&lt;br /&gt;more than 10 years, but may reduce its average weighted maturity to 10 years or&lt;br /&gt;below if warranted by market conditions.&lt;br /&gt; &lt;br /&gt;The Fund concentrates its investments in securities of issuers located in the&lt;br /&gt;State of Ohio and is non-diversified under the Investment Company Act of 1940,&lt;br /&gt;as amended (the "1940 Act").&lt;br /&gt; &lt;br /&gt;The Fund may invest more than 25% of its assets in municipal obligations within&lt;br /&gt;a particular segment of the bond market (such as housing agency bonds or airport&lt;br /&gt;bonds). The Fund may also invest more than 25% of its assets in private&lt;br /&gt;activity bonds and industrial development bonds which may be backed only by&lt;br /&gt;nongovernmental entities. Under normal circumstances, the Fund will limit its&lt;br /&gt;investment in securities whose income is subject to the alternative minimum tax&lt;br /&gt;to less than 20% of its assets. The Fund will not invest more than 25% of its&lt;br /&gt;assets in securities backed by nongovernmental entities that are in the same&lt;br /&gt;industry.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

You could lose money on your investment&lt;br /&gt;in the Fund and the Fund could return less than other investments. The Fund is&lt;br /&gt;subject to the principal risks summarized below.&lt;br /&gt; &lt;br /&gt;Credit Risk: The securities in the Fund&apos;s portfolio are subject to the&lt;br /&gt;possibility that a deterioration, whether sudden or gradual, in the financial&lt;br /&gt;condition of an issuer, or a deterioration in general economic conditions, could&lt;br /&gt;cause an issuer to fail to make timely payments of principal or interest, when&lt;br /&gt;due. This may cause the issuer&apos;s securities to decline in value.&lt;br /&gt; &lt;br /&gt;Interest Rate Risk: As interest rates rise, the value of fixed income securities&lt;br /&gt;the Fund owns will likely decrease. Longer-term securities are generally more&lt;br /&gt;volatile, so the longer the average maturity or duration of these securities,&lt;br /&gt;the greater their price risk. Duration is a measure of the expected life, taking&lt;br /&gt;into account any prepayment or call features of the security, of a fixed income&lt;br /&gt;security that is used to determine the price sensitivity of the security for a&lt;br /&gt;given change in interest rates. Specifically, duration is the change in the&lt;br /&gt;value of a fixed income security that will result from a 1% change in interest&lt;br /&gt;rates, and generally is stated in years. Maturity, on the other hand, is the&lt;br /&gt;date on which a fixed income security becomes due for payment of principal.&lt;br /&gt; &lt;br /&gt;Investment-Grade Securities Risk: Investment grade debt securities may be&lt;br /&gt;downgraded by a Nationally Recognized Statistical Rating Organization ("NRSRO")&lt;br /&gt;to below investment-grade status, which would increase the risk of holding these&lt;br /&gt;securities, or a rating may become stale in that it fails to reflect changes to&lt;br /&gt;an issuer&apos;s financial condition. Investment-grade debt securities rated in the&lt;br /&gt;lowest rating category by an NRSRO involve a higher degree of risk than&lt;br /&gt;fixed-income securities in the higher-rating categories. While such securities&lt;br /&gt;are considered investment-grade quality and are deemed to have adequate capacity &lt;br /&gt;for payment of principal and interest, such securities lack outstanding investment &lt;br /&gt;characteristics and have speculative characteristics as well.&amp;#xA0;&amp;#xA0;For example, changes &lt;br /&gt;in economic conditions or other circumstances are more likely to lead to a weakened &lt;br /&gt;capacity to make principal and interest payments than is the case with higher-grade &lt;br /&gt;securities.&lt;br /&gt; &lt;br /&gt;Management Risk: The value of your investment may decrease if the sub-advisor&apos;s&lt;br /&gt;judgment about the attractiveness, value, credit quality or income potential of&lt;br /&gt;a particular security is incorrect.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Municipal Securities Risk: The value of municipal securities may be affected by&lt;br /&gt;uncertainties in the municipal market related to legislation or litigation&lt;br /&gt;involving the taxation of municipal securities or the rights of municipal&lt;br /&gt;securities holders in the event of bankruptcy. In addition, the ongoing issues&lt;br /&gt;facing the national economy may negatively impact the economic performance of&lt;br /&gt;issuers of municipal securities, and may increase the likelihood that issuers of&lt;br /&gt;securities in which the Fund may invest may be unable to meet their obligations. &lt;br /&gt;Also, some municipal obligations may be backed by a letter of credit issued by a &lt;br /&gt;bank or other financial institution. Adverse developments affecting banks or other &lt;br /&gt;financial institutions could have a negative effect on the value of the Fund&apos;s &lt;br /&gt;portfolio securities.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Non-Diversification Risk: The Fund is non-diversified, which means that it may&lt;br /&gt;invest a greater percentage of its assets than diversified mutual funds in the&lt;br /&gt;securities of a limited number of issuers. The use of a non-diversified investment &lt;br /&gt;strategy may increase the volatility of the Fund&apos;s investment performance, as the &lt;br /&gt;Fund may be more susceptible to risks associated with a single economic, political &lt;br /&gt;or regulatory event than a diversified fund.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Prepayment Risk: Prepayment risk is the risk that a debt security may be paid&lt;br /&gt;off and proceeds invested earlier than anticipated. Prepayment risk is more&lt;br /&gt;prevalent during periods of falling interest rates.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Rating Agency Risk: Ratings represent the opinion of a Nationally Recognized&lt;br /&gt;Statistical Rating Organization ("NRSRO") regarding the quality of the security&lt;br /&gt;and are not a guarantee of quality. NRSROs may fail to make timely credit&lt;br /&gt;ratings in response to subsequent events. In addition, NRSROs are subject to an&lt;br /&gt;inherent conflict of interest because they are often compensated by the same&lt;br /&gt;issuers whose securities they grade.&lt;br /&gt; &lt;br /&gt;Sector Focus Risk: A fund that focuses its investments in the securities of a&lt;br /&gt;particular bond market sector (e.g., housing agency bonds or airport bonds) is&lt;br /&gt;subject to the risk that adverse circumstances will have a greater impact on the&lt;br /&gt;fund than a fund that does not focus its investments in a particular sector. It&lt;br /&gt;is possible that economic, business or political developments or other changes&lt;br /&gt;affecting one security in the area of focus will affect other securities in that&lt;br /&gt;area of focus in the same manner, thereby increasing the risk of such&lt;br /&gt;investments.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;State Risk: Political and economic conditions in the state of Ohio may impact&lt;br /&gt;the value of Ohio municipal obligations. The Fund may lose value due to&lt;br /&gt;decreased economic growth, increased unemployment and decreased tax revenue in&lt;br /&gt;the state of Ohio.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;An investment in the Fund is not a bank deposit and is not insured or guaranteed&lt;br /&gt;by the FDIC or any other government agency. As with any mutual fund, there is&lt;br /&gt;no guarantee that the Fund will achieve its goal.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

Generally, the Fund&apos;s yield will increase when&lt;br /&gt;interests rate increase and will decrease when interest rates decrease.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Management Risk: The value of your investment may decrease if the sub-advisor&apos;s&lt;br /&gt;judgment about the attractiveness, value, credit quality or income potential of&lt;br /&gt;a particular security is incorrect.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Market Disruption Risk: During periods of extreme market volatility, prices of&lt;br /&gt;securities held by the Fund may be negatively impacted due to imbalances between&lt;br /&gt;credit market participants seeking to sell the same or similar securities and&lt;br /&gt;market participants willing or able to buy such securities. As a result, the&lt;br /&gt;market prices of securities held by the Fund could go down, at times without &lt;br /&gt;regard to the financial condition of or specific events impacting the issuer &lt;br /&gt;of the security. A significant enough market disruption or drop in market &lt;br /&gt;prices of securities held by the Fund, especially at a time during which the &lt;br /&gt;Fund needs to sell securities to meet shareholder redemption requests, could &lt;br /&gt;cause the value of the Fund&apos;s shares to decrease to a price less than $1.00 &lt;br /&gt;per share.&lt;br /&gt; &lt;br /&gt;Municipal Securities Risk: The value of municipal securities may be affected &lt;br /&gt;by uncertainties in the municipal market related to legislation or litigation&lt;br /&gt;involving the taxation of municipal securities or the rights of municipal&lt;br /&gt;securities holders in the event of bankruptcy. In addition, the ongoing issues&lt;br /&gt;facing the national economy may negatively impact the economic performance of&lt;br /&gt;issuers of municipal securities, and may increase the likelihood that issuers &lt;br /&gt;of securities in which the Fund may invest may be unable to meet their&lt;br /&gt;obligations. Also, some municipal obligations may be backed by a letter of&lt;br /&gt;credit issued by a bank or other financial institution. Adverse developments&lt;br /&gt;affecting banks or other financial institutions could have a negative effect &lt;br /&gt;on the value of the Fund&apos;s portfolio securities. This could cause the value of &lt;br /&gt;the Fund&apos;s shares to decrease to a price less than $1.00 per share.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Non-Diversification Risk: The Fund is non-diversified, which means that it may&lt;br /&gt;invest a greater percentage of its assets than diversified mutual funds in the&lt;br /&gt;securities of a limited number of issuers. The use of a non-diversified investment &lt;br /&gt;strategy may increase the volatility of the Fund&apos;s investment performance, as the &lt;br /&gt;Fund may be more susceptible to risks associated with a single economic, political &lt;br /&gt;or regulatory event than a diversified fund.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Rating Agency Risk: Ratings represent the opinion of a Nationally Recognized&lt;br /&gt;Statistical Rating Organization ("NRSRO") regarding the quality of the security&lt;br /&gt;and are not a guarantee of quality. NRSROs may fail to make timely credit&lt;br /&gt;ratings in response to subsequent events. In addition, NRSROs are subject to &lt;br /&gt;an inherent conflict of interest because they are often compensated by the same&lt;br /&gt;issuers whose securities they grade.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Sector Focus Risk: A fund that focuses its investments in the securities of a&lt;br /&gt;particular bond market sector (e.g., housing agency bonds or airport bonds) is&lt;br /&gt;subject to the risk that adverse circumstances will have a greater impact on the&lt;br /&gt;fund than a fund that does not focus its investments in a particular sector. It&lt;br /&gt;is possible that economic, business or political developments or other changes&lt;br /&gt;affecting one security in the area of focus will affect other securities in that&lt;br /&gt;area of focus in the same manner, thereby increasing the risk of such&lt;br /&gt;investments.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;State Risk: Political and economic conditions in the state of Ohio may impact&lt;br /&gt;the value of Ohio municipal obligations. The Fund&apos;s yield may decrease due to&lt;br /&gt;decreased economic growth, increased unemployment and decreased tax revenue in&lt;br /&gt;the state of Ohio.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

Although the Fund seeks to preserve&lt;br /&gt;the value of your investment at $1.00 per share, it is possible to lose money by&lt;br /&gt;investing in the Fund. There is no guarantee that the Fund will be able to&lt;br /&gt;avoid a negative yield. The Fund is subject to the Principal Risks summarized&lt;br /&gt;below.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Credit Risk: The securities in the Fund&apos;s portfolio are subject to the&lt;br /&gt;possibility that a deterioration, whether sudden or gradual, in the financial&lt;br /&gt;condition of an issuer, or a deterioration in general economic conditions, could&lt;br /&gt;cause an issuer to fail to make timely payments of principal or interest, when&lt;br /&gt;due. This may cause the issuer&apos;s securities to decline in value.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Interest Rate Risk: The yield of the Fund will vary from day to day due to&lt;br /&gt;changes in interest rates. Generally, the Fund&apos;s yield will increase when&lt;br /&gt;interests rate increase and will decrease when interest rates decrease.&lt;br /&gt; &lt;br /&gt;Management Risk: The value of your investment may decrease if the sub-advisor&apos;s&lt;br /&gt;judgment about the attractiveness, value, credit quality or income potential of&lt;br /&gt;a particular security is incorrect.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Market Disruption Risk: During periods of extreme market volatility, prices of&lt;br /&gt;securities held by the Fund may be negatively impacted due to imbalances between&lt;br /&gt;credit market participants seeking to sell the same or similar securities and market &lt;br /&gt;participants willing or able to buy such securities. As a result, the market prices &lt;br /&gt;of securities held by the Fund could go down, at times without regard to the financial &lt;br /&gt;condition of or specific events impacting the issuer of the security. A significant &lt;br /&gt;enough market disruption or drop in market prices of securities held by the Fund, &lt;br /&gt;especially at a time during which the Fund needs to sell securities to meet shareholder &lt;br /&gt;redemption requests, could cause the value of the Fund&apos;s shares to decrease to a &lt;br /&gt;price less than $1.00 per share.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Municipal Securities Risk: The value of municipal securities may be affected &lt;br /&gt;by uncertainties in the municipal market related to legislation or litigation&lt;br /&gt;involving the taxation of municipal securities or the rights of municipal&lt;br /&gt;securities holders in the event of bankruptcy. In addition, the ongoing issues&lt;br /&gt;facing the national economy may negatively impact the economic performance &lt;br /&gt;of issuers of municipal securities, and may increase the likelihood that &lt;br /&gt;issuers of securities in which the Fund may invest may be unable to meet &lt;br /&gt;their obligations. Also, some municipal obligations may be backed by a letter &lt;br /&gt;of credit issued by a bank or other financial institution. Adverse developments&lt;br /&gt;affecting banks or other financial institutions could have a negative effect on&lt;br /&gt;the value of the Fund&apos;s portfolio securities. This could cause the value of the&lt;br /&gt;Fund&apos;s shares to decrease to a price less than $1.00 per share.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Rating Agency Risk: Ratings represent the opinion of a Nationally Recognized&lt;br /&gt;Statistical Rating Organization ("NRSRO") regarding the quality of the security&lt;br /&gt;and are not a guarantee of quality. NRSROs may fail to make timely credit&lt;br /&gt;ratings in response to subsequent events. In addition, NRSROs are subject to &lt;br /&gt;an inherent conflict of interest because they are often compensated by the &lt;br /&gt;same issuers whose securities they grade.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;Sector Focus Risk: A fund that focuses its investments in the securities of a&lt;br /&gt;particular bond market sector (e.g., housing agency bonds or airport bonds) is&lt;br /&gt;subject to the risk that adverse circumstances will have a greater impact on the&lt;br /&gt;fund than a fund that does not focus its investments in a particular sector. It&lt;br /&gt;is possible that economic, business or political developments or other changes&lt;br /&gt;affecting one security in the area of focus will affect other securities in that&lt;br /&gt;area of focus in the same manner, thereby increasing the risk of such&lt;br /&gt;investments.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>
