Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.

When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p> Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p> Investing in mortgage-backed and asset-backed securities poses additional risks, principally with respect to increased credit risk and prepayment risk. Many mortgage-backed securities and asset-backed securities may be prepaid prior to maturity. During periods of falling interest rates, prepayments may accelerate, which would require an investing Fund to reinvest the proceeds at a lower interest rate. For more detailed information, please see the &#8220;Mortgage-Backed Securities&#8221; and &#8220;Asset-Backed Securities&#8221; discussions in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p><p>Investing in foreign securities poses additional risks.

These include (1) debt securities issued or guaranteed by the U.S. Government and foreign governments and their agencies and instrumentalities, political subdivisions of foreign governments (such as provinces and municipalities), and supranational organizations (such as the World Bank); (2) debt securities, loans and commercial paper issued by U.S. and foreign companies; (3) U.S. and foreign mortgage-backed and asset-backed debt securities; (4) municipal securities, which are debt obligations issued by state and local governments, territories and possessions of the United States, regional governmental authorities, and their agencies and instrumentalities, the interest on which may, or may not, be exempt from Federal income tax; and (5) dividend-paying convertible stock. Investment grade debt securities are rated within the four highest grades by at least one of the major rating agencies, such as Standard &#038; Poor&#8217;s (at least BBB-), Moody&#8217;s (at least Baa3) or Fitch (at least BBB-), or are securities that Payden determines to be of comparable quality. Further information regarding credit ratings is in Appendix A.</p> <p>Except for mortgage-backed U.S. Government Obligations, the Fund invests in debt securities with a maximum maturity of ten years. Under normal market conditions, the Fund&#8217;s average portfolio maturity (on a dollar-weighted basis) is generally less than five years. The Fund invests in mortgage-backed U.S. Government Obligations with a maximum effective duration of five years. Duration is a mathematical concept which uses anticipated cash flows to measure the price volatility of a security and is calculated in terms of years. For example, when interest rates move up or down, the price of a security with a duration of four years will move roughly twice as much as a security with a duration of two years.</p> <p>The Fund invests in debt securities that Payden believes offer attractive yields and are undervalued relative to securities of similar credit quality and interest rate sensitivity. Payden reviews historical interest rate spread relationships, as well as economic and issuer scenario analyses, in making investment decisions.</p> <p>The Fund is &#8220;non-diversified,&#8221; which means that Payden may from time to time invest a larger percentage of the Fund&#8217;s assets in securities of a limited number of issuers.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

The following risks could also affect the value of your investment in the Fund:</p> <p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p> <p>Debt obligations issued by the U.S. Treasury, which include U.S. Treasury bills, notes and bonds, are backed by the full faith and credit of the U.S. Government. Debt obligations issued by agencies chartered by the U.S. Government, which are classified as Government sponsored enterprises, may or may not be backed by the full faith and credit of the U.S. Government. For example, GNMA mortgage-backed securities are backed by the full faith and credit of the U.S. Government. On the other hand, FNMA and FHLMC mortgage-backed securities are not. However, each of the FNMA and FHLMC benefits from the Preferred Stock Purchase Agreement it has with the U.S. Treasury which is expected to provide them with the necessary cash resources to meet their obligations through 2012.

A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns usually decline. When interest rates fall, the prices of these securities usually increase. However, falling interest rates typically will not affect the prices of GNMA Securities as much as the prices of comparable debt securities because the markets tend to discount GNMA Security prices for prepayment risk when interest rates fall. Further, the longer the Fund&#8217;s average portfolio maturity, generally the greater the price fluctuation. Finally, the price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p>The Fund is subject to the prepayment risk applicable to mortgages underlying the GNMA Securities and other mortgage-backed U.S. Government Obligations. Prepayment risk is the chance that the mortgage-backed bonds will be paid off early due to homeowners refinancing their mortgages during periods of falling interest rates. Forced to reinvest the unanticipated proceeds at lower rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling rates. Prepayment risk is high for the Fund. In addition, the Fund is subject to the credit risk associated with these securities, including the market&#8217;s perception of the creditworthiness of the issuing Federal agency, as well as the credit quality of the underlying assets. For more detailed information, please see the &#8220;Mortgage-Backed Securities&#8221; and &#8220;Asset-Backed Securities&#8221; discussions in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p><p>Debt obligations issued by the U.S. Treasury, which include U.S. Treasury bills, notes and bonds, are backed by the full faith and credit of the U.S. Government. Debt obligations issued by agencies chartered by the U.S. Government, which are classified as Government sponsored enterprises, may or may not be backed by the full faith and credit of the U.S. Government. For example, GNMA mortgage-backed securities are backed by the full faith and credit of the U.S. Government. On the other hand, FNMA and FHLMC mortgage-backed securities are not.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p>To the extent the Fund invests in corporate debt securities, the Fund is subject to credit risk, that is, the risk that the corporate issuer of a debt security will be unable to make interest or principal payments on time. A debt security&#8217;s credit rating reflects the credit risk associated with the debt obligation. Higher-rated debt securities involve lower credit risk than lower-rated debt securities. Generally, credit risk is higher for corporate and foreign government debt securities than for U.S. Government securities.</p><p>Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p>Investing in mortgage-backed and asset-backed securities poses additional risks, principally with respect to increased credit risk and prepayment risk. Many mortgage-backed securities and asset-backed securities may be prepaid prior to maturity. During periods of falling interest rates, prepayments may accelerate, which would require an investing Fund to reinvest the proceeds at a lower interest rate. For more detailed information, please see the &#8220;Mortgage-Backed Securities&#8221; and &#8220;Asset-Backed Securities&#8221; discussions in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p><p>Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities.</p><p> The Fund is &#8220;non-diversified,&#8221; which means that compared with diversified funds, the Fund may invest a greater percentage of its assets in a particular issuer. Accordingly, events that affect a few &#8212; or even one &#8212; of the Fund&#8217;s investments may have a greater impact on the value of the Fund&#8217;s shares than they would if the Fund were diversified.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p>To the extent the Fund invests in corporate debt securities, the Fund is subject to credit risk, that is, the risk that the corporate issuer of a debt security will be unable to make interest or principal payments on time. A debt security&#8217;s credit rating reflects the credit risk associated with the debt obligation. Higher-rated debt securities involve lower credit risk than lower-rated debt securities. Generally, credit risk is higher for corporate and foreign government debt securities than for U.S. Government securities.</p><p>Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p>Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities.</p><p>As indicated above, even though the Fund may use derivative instruments as a hedging mechanism, these instruments involve risks different from, or possibly greater than, the risks associated with investing directly in securities and other more traditional investments.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns usually decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation.

The amount of public information available about Municipal Securities is generally less than that for corporate equities or bonds, and the Fund&#8217;s investment performance may therefore be more dependent on Payden&#8217;s analytical abilities than if the Fund were to invest in stocks or taxable bonds. The secondary market for Municipal Securities also tends to be less well-developed and less liquid than many other securities markets, which may adversely affect the Fund&#8217;s ability to sell its bonds at attractive prices or at prices approximating those at which the Fund currently values them.</p><p>Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p> As a temporary defensive measure, the Fund may also invest up to 20% of its total assets in debt securities that pay interest income subject to Federal income tax.</p><p>The Fund is &#8220;non-diversified,&#8221; which means that compared with diversified funds, the Fund may invest a greater percentage of its assets in a particular issuer. Accordingly, events that affect a few &#8212; or even one &#8212; of the Fund&#8217;s investments may have a greater impact on the value of the Fund&#8217;s shares than they would if the Fund were diversified.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns usually decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p>Investing in the Municipal Securities market involves certain risks. The amount of public information available about Municipal Securities is generally less than that for corporate equities or bonds, and the Fund&#8217;s investment performance may therefore be more dependent on Payden&#8217;s analytical abilities than if the Fund were to invest in stocks or taxable bonds. The secondary market for Municipal Securities also tends to be less well-developed and less liquid than many other securities markets, which may adversely affect the Fund&#8217;s ability to sell its bonds at attractive prices or at prices approximating those at which the Fund currently values them.</p><p>Because the Fund invests primarily in California Municipal Securities, its performance is subject to economic and political developments in the State of California. California Municipal Securities may be adversely affected by political and economic conditions and developments within California and the nation as a whole. California continues to experience significant financial stress primarily from ongoing weakness in the state economy, high unemployment and ongoing revenue shortfalls. While the consensus among economists is that California appears to be recovering from the economic downturn, California&#8217;s budgetary and fiscal condition remain in a fragile state and economists emphasize that uncertain revenue estimates and market volatility make any projection highly uncertain. As of February 24, 2011, California&#8217;s general obligation bonds were rated A1 by Moody&#8217;s, A- by Standard &#038; Poor&#8217;s, and A- by Fitch Ratings. Though bonds issued by California remain &#8220;investment grade&#8221; according to each ratings agency, California currently has the lowest credit rating of any state, and the agencies continue to monitor California&#8217;s budget outlook closely to determine whether to alter the ratings.</p><p>Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p>As a temporary defensive measure, the Fund may also invest up to 20% of its total assets in debt securities that pay interest income subject to Federal income tax.</p><p>The Fund is &#8220;non-diversified,&#8221; which means that compared with diversified funds, the Fund may invest a greater percentage of its assets in a particular issuer. Accordingly, events that affect a few &#8212; or even one &#8212; of the Fund&#8217;s investments may have a greater impact on the value of the Fund&#8217;s shares than they would if the Fund were diversified.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The following risks could also affect the value of your investment in the Fund:</p> <p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The value of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p> <p>Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. In addition, emerging markets tend to be more volatile than the U.S. market or developed foreign markets.</p> <p>Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p> <p>Investing in mortgage-backed and asset-backed securities poses additional risks, principally with respect to increased credit risk and prepayment risk. Many mortgage-backed securities and asset-backed securities may be prepaid prior to maturity. During periods of falling interest rates, prepayments may accelerate, which would require an investing Fund to reinvest the proceeds at a lower interest rate. For more detailed information, please see the &#8220;Mortgage-Backed Securities&#8221; and &#8220;Asset-Backed Securities&#8221; discussions in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p> <p>Investing in equity securities poses certain risks, including a sudden decline in a holding&#8217;s share price, or an overall decline in the stock market.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The value of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p>Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. In addition, emerging markets tend to be more volatile than the U.S. market or developed foreign markets.</p><p>Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p>Investing in mortgage-backed and asset-backed securities poses additional risks, principally with respect to increased credit risk and prepayment risk. Many mortgage-backed securities and asset-backed securities may be prepaid prior to maturity. During periods of falling interest rates, prepayments may accelerate, which would require an investing Fund to reinvest the proceeds at a lower interest rate. For more detailed information, please see the &#8220;Mortgage-Backed Securities&#8221; and &#8220;Asset-Backed Securities&#8221; discussions in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p><p>Investing in equity securities poses certain risks, including a sudden decline in a holding&#8217;s share price, or an overall decline in the stock market. The value of the Fund&#8217;s investment in any such securities will fluctuate on a day-to-day basis with movements in the stock market, as well as in response to the activities of individual companies whose equity securities the Fund owns.</p><p>The Fund is &#8220;non-diversified,&#8221; which means that compared with diversified funds, the Fund may invest a greater percentage of its assets in a particular issuer.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund&#8217;s average portfolio maturity, the greater the price fluctuation. The value of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p>Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. In addition, emerging markets tend to be more volatile than the U.S. market or developed foreign markets.</p><p>Below investment grade securities (commonly called &#8220;junk bonds&#8221;) are speculative and involve a greater risk of default and price change due to changes in the issuer&#8217;s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p>Investing in equity securities poses certain risks, including a sudden decline in a holding&#8217;s share price, or an overall decline in the stock market.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The weight it gives to a particular factor depends on Payden&#8217;s view of the circumstances at the time of purchase, and some portfolio holdings may not meet all of the criteria: (1) companies that have a dominant market share, or are in specialized market niches; (2) companies with strong earnings and cash flows; and (3) companies that have a global presence, that benefit from size and scale, and that serve underpenetrated and rapidly growing markets.</p><p>Payden believes that companies with these characteristics should have relatively low business risk and relatively high ability to sustain earnings growth.</p><p> The Fund is &#8220;non-diversified,&#8221; which means that Payden may from time to time invest a larger percentage of the Fund&#8217;s assets in securities of a limited number of issuers.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

The following risks could also affect the value of your investment in the Fund:</p><p>Investing in equity securities poses certain risks, including a sudden decline in a holding&#8217;s share price, or an overall decline in the stock market. The value of the Fund&#8217;s investment in any such securities will fluctuate on a day-to-day basis with movements in the stock market, as well as in response to the activities of individual companies whose equity securities the Fund owns.</p><p>Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. In addition, emerging markets tend to be more volatile than the U.S. market or developed foreign markets.</p><p>Because an ETF is designed to track closely the performance of a particular market index, if the underlying index (such as an equity-based index) is subject to increased volatility, the ETF may be subject to such increased volatility. Similarly, it may be subject to the risks of trading halts and other similar risks to which securities trading on an exchange are subject. Finally, because the Fund must bear the cost of investing in any ETF, the acquired fund fees and expenses of the ETF may, if significant, have an adverse effect on the Fund&#8217;s performance. For more detailed information, please see the &#8220;Exchange-Traded Funds&#8221; discussion in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p><p>The Fund may invest a significant portion of its total assets in companies in various technology industries.

The following risks could also affect the value of your investment in the Fund:</p> <p>Investing in equity securities poses certain risks, including a sudden decline in a holding&#8217;s share price, or an overall decline in the stock market. The value of the Fund&#8217;s investment in any such securities will fluctuate on a day-to-day basis with movements in the stock market, as well as in response to the activities of individual companies whose equity securities the Fund owns.</p> <p>Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. In addition, emerging markets tend to be more volatile than the U.S. market or developed foreign markets.</p> <p>The use of derivative instruments, such as options, futures or swaps, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other more traditional instruments. For further information, please see the &#8220;Derivative Instruments&#8221; discussion in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p> <p>The Fund&#8217;s use of short selling may involve more risk than a fund that does not engage in that tactic. When the Fund takes a long position, it purchases an equity security outright. In a short sale, the Fund sells a borrowed equity security in anticipation that the market price of the security will decline. If the market price of the security increases after the Fund borrows the security, the Fund will suffer a loss when it replaces the borrowed security at the higher price. In addition, the Fund may not always be able to borrow the security at a particular time or at an acceptable price.</p> <p>By investing the proceeds received from selling securities short, the Fund is employing a form of leverage. Leverage may increase the Fund&#8217;s exposure to long equity positions and make any changes in the Fund&#8217;s net asset value greater than it would be without the use of leverage. This could result in increased volatility of returns. There is no guarantee that the Fund will leverage its portfolio, or if it does, that the Fund&#8217;s leveraging strategy will be successful. The Fund cannot guarantee that the use of leverage will produce a higher return on an investment.</p> <p>Because an ETF is designed to track closely the performance of a particular market index, if the underlying index (such as an equity-based index) is subject to increased volatility, the ETF may be subject to such increased volatility. Similarly, it may be subject to the risks of trading halts and other similar risks to which securities trading on an exchange are subject. For more detailed information, please see the &#8220;Exchange-Traded Funds&#8221; discussion in the &#8220;More About Investment Strategies, Related Risks and Disclosure of Portfolio Holdings&#8221; section in this Prospectus.</p> <p>Gains from selling securities short are generally treated as short-term capital gains that are taxed at ordinary income tax rates when distributed to investors.</p> <p>The Fund is &#8220;non-diversified,&#8221; which means that compared with diversified funds, the Fund may invest a greater percentage of its assets in a particular issuer.
