If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time.

In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

Furthermore, there can be no assurance that the Fund&#x2019;s affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share. In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

Changes in the rate at which prepayments or redemptions occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events.

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund&#x2019;s shares may fluctuate in response to events affecting that industry or sector.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time. Such securities also may lose value.&lt;/span&gt;</oef:RiskTextBlock>

Furthermore, there can be no assurance that the Fund&#x2019;s affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share. In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due. In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

Changes in the rate at which prepayments or redemptions occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future.

Similarly, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund&#x2019;s shares may fluctuate in response to events affecting that industry or sector.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time.

These enhanced risks may include additional counterparty risk (the risk that the counterparty will not fulfill its contractual obligations) and call risk (the risk that the instruments will be called and the proceeds may need to be reinvested). Additionally, an active trading market for such instruments may not exist. To the extent that a structured product provides a put, the Fund may receive a lower interest rate in return for such feature and will be subject to the risk that the put provider will be unable to honor the put feature (purchase the security). Finally, short-term municipal or tax-exempt structured products may present tax issues not presented by investments in other short-term municipal or tax-exempt securities. These issues might be resolved in a manner adverse to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

Furthermore, there can be no assurance that the Fund&#x2019;s affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share. In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events.

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due. In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events.

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due. In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary.

A blockchain is an open, distributed ledger that records transactions between two parties in a verifiable and append-only manner using cryptography. Transactions on the blockchain are verified and authenticated by computers on the network. The process of authenticating a transaction before it is recorded seeks to ensure that only valid and authorized transactions are permanently recorded on the blockchain in collections of transactions called &#x201c;blocks.&#x201d; Blockchain networks are based upon software source code that establishes and governs their respective cryptographic systems for verifying transactions. Complex information technology and communications systems, such as blockchain networks, are subject to a number of different threats or risks (including operational, information security, cyber-attacks and related risks) that could adversely affect the Fund, its shareholders and intermediaries through whom shareholders purchase and redeem shares of the Fund. The use of blockchain technology is relatively new and still evolving. The Fund, the adviser and/or its affiliates will not be responsible for any loss in connection with the use of blockchain technology by the financial intermediaries. Shareholders should contact their financial intermediaries about whether or how they use blockchain technology and the associated risks.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;magnitude of such changes.

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

Changes in the rate at which prepayments or redemptions occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events.

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events.

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

Furthermore, there can be no assurance that the Fund&#x2019;s affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share. In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due. In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, contagion risk within a particular industry or sector or to other industries or sectors, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund&#x2019;s shares may fluctuate in response to events affecting that industry or sector.&lt;/span&gt;</oef:RiskTextBlock>

The London Interbank Offering Rate (&#x201c;LIBOR&#x201d;) was a leading floating rate benchmark used in loans, notes, derivatives and other instruments or investments. After the global financial crisis, regulators globally determined that existing interest rate benchmarks should be reformed based on a number of factors, including that LIBOR and other interbank offering rates (&#x201c;IBORs&#x201d;) may no longer be representative of the underlying markets and, as a result, publication of all LIBOR settings has ceased. New or alternative reference rates have since been used in place of LIBOR.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Replacement rates that have been identified include the Secured Overnight Financing Rate (&#x201c;SOFR,&#x201d; which is intended to replace U.S.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;dollar LIBOR and measures the cost of U.S dollar overnight borrowings collateralized by treasuries) and the Sterling Overnight Index Average rate (&#x201c;SONIA,&#x201d;&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;which is intended to replace pound sterling LIBOR and measures the overnight interest rate paid by banks in the sterling market). Markets are slowly developing in response to these new rates. As a result of the benchmark reforms, the Adviser, Sub-Advisers, and the Funds have generally transitioned to successor or alternative reference rates as necessary.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Although the transition process away&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;from IBORs for most instruments has been completed, there is no assurance that any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that it will have the same volume or liquidity as did LIBOR prior to its discontinuance, which may affect the value, volatility, liquidity, or return on certain of a Fund&#x2019;s loans, notes, derivatives and other instruments or investments and result in costs incurred in connection with changing reference rates used for positions, closing out positions, and entering into new trades. The transition from LIBOR to alternative reference rates may result in operational issues for a Fund or its investments. Moreover,&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;certain aspects of the transition from IBORs will rely on the actions of third-party market participants, such as clearing houses, trustees, administrative agents, asset servicers and certain service providers; no assurances can be given as to the impact of the transition away from LIBOR on&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;a Fund or its investments.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;These risks may also apply with respect to changes in connection with other IBORs (e.g., Euribor) and a wide range of other index levels, rates and values that are treated as &#x201c;benchmarks&#x201d; and are the subject of recent regulatory reform.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

Similarly, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

These enhanced risks may include additional counterparty risk (the risk that the counterparty will not fulfill its contractual obligations) and call risk (the risk that the instruments will be called and the proceeds may need to be reinvested). Additionally, an active trading market for such instruments may not exist. To the extent that a structured product provides a put, the Fund may receive a lower interest rate in return for such feature and will be subject to the risk that the put provider will be unable to honor the put feature (purchase the security). Finally, short-term municipal or tax-exempt structured products may present tax issues not presented by investments in other short-term municipal or tax-exempt securities. These issues might be resolved in a manner adverse to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time. Such securities also may lose value.&lt;/span&gt;</oef:RiskTextBlock>

In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due. In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

Changes in the rate at which prepayments or redemptions occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The Fund may invest in variable and floating rate &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes.

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

These risks generally include interest rate risk, credit risk and risk associated with regulatory changes in the financial services industry. In addition, financial services companies are highly dependent on the supply of short-term financing.&lt;/span&gt;</oef:RiskTextBlock>

The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. In certain markets where securities and other instruments are not traded &#x201c;delivery versus payment,&#x201d; the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Foreign market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund's ability to buy and sell securities. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time.

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due.

The disposition of some of the securities held by the Fund may be restricted under federal securities laws.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets.

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time.

In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due. In the case of a default by a borrowing fund and to the extent that the loan is collateralized, the Fund could take possession of collateral that the Fund is not permitted to hold and, therefore, would be required to dispose of such collateral as soon as possible, which could result in a loss to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The Fund may invest in variable and floating rate &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes.

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

These risks generally include interest rate risk, credit risk and risk associated with regulatory changes in the financial services industry. In addition, financial services companies are highly dependent on the supply of short-term financing.&lt;/span&gt;</oef:RiskTextBlock>

In certain markets where securities and other instruments are not traded &#x201c;delivery versus payment,&#x201d; the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Foreign market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund's ability to buy and sell securities. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time.

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due.

The disposition of some of the securities held by the Fund may be restricted under federal securities laws.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund&#x2019;s shares may fluctuate in response to events affecting that industry or sector.&lt;/span&gt;</oef:RiskTextBlock>

The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time.

These enhanced risks may include additional counterparty risk (the risk that the counterparty will not fulfill its contractual obligations) and call risk (the risk that the instruments will be called and the proceeds may need to be reinvested). Additionally, an active trading market for such instruments may not exist. To the extent that a structured product provides a put, the Fund may receive a lower interest rate in return for such feature and will be subject to the risk that the put provider will be unable to honor the put feature (purchase the security). Finally, short-term municipal or tax-exempt structured products may present tax issues not presented by investments in other short-term municipal or tax-exempt securities. These issues might be resolved in a manner adverse to the Fund.&lt;/span&gt;</oef:RiskTextBlock>

In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund&#x2019;s ability to sell the securities at any given time.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events.

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes.

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

These risks generally include interest rate risk, credit risk and risk associated with regulatory changes in the financial services industry.

Foreign market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund's ability to buy and sell securities. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.&lt;/span&gt;</oef:RiskTextBlock>

The London Interbank Offering Rate (&#x201c;LIBOR&#x201d;) was a leading floating rate benchmark used in loans, notes, derivatives and other instruments or investments. After the global financial crisis, regulators globally determined that existing interest rate benchmarks should be reformed based on a number of factors, including that LIBOR and other interbank offering rates (&#x201c;IBORs&#x201d;) may no longer be representative of the underlying markets and, as a result, publication of all LIBOR settings has ceased. New or alternative reference rates have since been used in place of LIBOR.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Replacement rates that have been identified include the Secured Overnight Financing Rate (&#x201c;SOFR,&#x201d; which is intended to replace U.S.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;dollar LIBOR and measures the cost of U.S dollar overnight borrowings collateralized by treasuries) and the Sterling Overnight Index Average &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;rate (&#x201c;SONIA,&#x201d;&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;which is intended to replace pound sterling LIBOR and measures the overnight interest rate paid by banks in the sterling market). Markets are slowly developing in response to these new rates. As a result of the benchmark reforms, the Adviser, Sub-Advisers, and the Funds have generally transitioned to successor or alternative reference rates as necessary.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Although the transition process away&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;from IBORs for most instruments has been completed, there is no assurance that any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that it will have the same volume or liquidity as did LIBOR prior to its discontinuance, which may affect the value, volatility, liquidity, or return on certain of a Fund&#x2019;s loans, notes, derivatives and other instruments or investments and result in costs incurred in connection with changing reference rates used for positions, closing out positions, and entering into new trades. The transition from LIBOR to alternative reference rates may result in operational issues for a Fund or its investments. Moreover,&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;certain aspects of the transition from IBORs will rely on the actions of third-party market participants, such as clearing houses, trustees, administrative agents, asset servicers and certain service providers; no assurances can be given as to the impact of the transition away from LIBOR on&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;a Fund or its investments.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;These risks may also apply with respect to changes in connection with other IBORs (e.g., Euribor) and a wide range of other index levels, rates and values that are treated as &#x201c;benchmarks&#x201d; and are the subject of recent regulatory reform.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

Additionally, an active trading market for such instruments may not exist. To the extent that a structured product provides a put, the Fund may receive a lower interest rate in return for such feature and will be subject to the risk that the put provider will be unable to honor the put feature (purchase the security). Finally, short-term municipal or tax-exempt structured products may present tax issues not presented by investments in other short-term municipal or tax-exempt securities.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

The London Interbank Offering Rate (&#x201c;LIBOR&#x201d;) was a leading floating rate benchmark used in loans, notes, derivatives and other instruments or investments. After the global financial crisis, regulators globally determined that existing interest rate benchmarks should be reformed based on a number of factors, including that LIBOR and other interbank offering rates (&#x201c;IBORs&#x201d;) may no longer be representative of the underlying markets and, as a result, publication of all LIBOR settings has ceased. New or alternative reference rates have since been used in place of LIBOR.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Replacement rates that have been identified include the Secured Overnight Financing Rate (&#x201c;SOFR,&#x201d; which is intended to replace U.S.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;dollar LIBOR and measures the cost of U.S dollar overnight borrowings collateralized by treasuries) and the Sterling Overnight Index Average rate (&#x201c;SONIA,&#x201d;&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;which is intended to replace pound sterling LIBOR and measures the overnight interest rate paid by banks in the sterling market). Markets are slowly developing in response to these new rates. As a result of the benchmark reforms, the Adviser, Sub-Advisers, and the Funds have generally transitioned to successor or alternative reference rates as necessary.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Although the transition process away&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;from IBORs for most instruments has been completed, there is no assurance that any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that it will have the same volume or liquidity as did LIBOR prior to its discontinuance, which may affect the value, volatility, liquidity, or return on certain of a Fund&#x2019;s loans, notes, derivatives and other instruments or investments and result in costs incurred in connection with changing reference rates used for positions, closing out positions, and entering into new trades. The transition from LIBOR to alternative reference rates may result in operational issues for a Fund or its investments. Moreover,&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;certain aspects of the transition from IBORs will rely on the actions of third-party market participants, such as clearing houses, trustees, administrative agents, asset servicers and certain service providers; no assurances can be given as to the impact of the transition away from LIBOR on&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;a Fund or its investments.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;These risks may also apply with respect to changes in connection with other IBORs (e.g., Euribor) and a &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;wide range of other index levels, rates and values that are treated as &#x201c;benchmarks&#x201d; and are the subject of recent regulatory reform.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

Furthermore, there can be no assurance that the Fund&#x2019;s affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share. In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes.

Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation.

The London Interbank Offering Rate (&#x201c;LIBOR&#x201d;) was a leading floating rate benchmark used in loans, notes, derivatives and other instruments or investments. After the global financial crisis, regulators globally determined that existing interest rate benchmarks should be reformed based on a number of factors, including that LIBOR and other interbank offering rates (&#x201c;IBORs&#x201d;) may no longer be representative of the underlying markets and, as a result, publication of all LIBOR settings has ceased. New or alternative reference rates have since been used in place of LIBOR.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Replacement rates that have been identified include the Secured Overnight Financing Rate (&#x201c;SOFR,&#x201d; which is intended to replace U.S.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;dollar LIBOR and measures the cost of U.S dollar overnight borrowings collateralized by treasuries) and the Sterling Overnight Index Average &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;rate (&#x201c;SONIA,&#x201d;&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;which is intended to replace pound sterling LIBOR and measures the overnight interest rate paid by banks in the sterling market). Markets are slowly developing in response to these new rates. As a result of the benchmark reforms, the Adviser, Sub-Advisers, and the Funds have generally transitioned to successor or alternative reference rates as necessary.&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;Although the transition process away&lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;line-height:11pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;from IBORs for most instruments has been completed, there is no assurance that any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that it will have the same volume or liquidity as did LIBOR prior to its discontinuance, which may affect the value, volatility, liquidity, or return on certain of a Fund&#x2019;s loans, notes, derivatives and other instruments or investments and result in costs incurred in connection with changing reference rates used for positions, closing out positions, and entering into new trades.

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Prices of the Fund&#x2019;s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund&#x2019;s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer&#x2019;s securities.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund&#x2019;s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.&lt;/span&gt;</oef:RiskTextBlock>

Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>

When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/span&gt;</oef:RiskTextBlock>

The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund&#x2019;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.&lt;/span&gt;</oef:RiskTextBlock>

If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.&lt;/span&gt;</oef:RiskTextBlock>

Securities in the Fund&#x2019;s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events.

The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality&#x2019;s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund&#x2019;s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund&#x2019;s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial Narrow;font-size:10pt;"&gt;Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund&#x2019;s investments. &lt;/span&gt;&lt;span style="font-family:Arial Narrow;font-size:10pt;"&gt;In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality&#x2019;s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund&#x2019;s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.&lt;/span&gt;</oef:RiskTextBlock>

U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government will provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.&lt;/span&gt;</oef:RiskTextBlock>
