The information above reflects the direct expenses of the fund and its allocated share of expenses of U.S. Treasury Reserves Portfolio. Principal investment strategies The fund is a money market fund which invests all of its assets in direct obligations of the U.S. Treasury, including U.S. Treasury bills, notes and bonds. The fund will not enter into repurchase agreements, but may enter into reverse repurchase agreements to satisfy redemption requests or for other temporary or emergency purposes. Although the fund invests in U.S. government obligations, an investment in the fund is neither insured nor guaranteed by the U.S. government. <br/><br/>As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. Certain risks An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. <br /><br />Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the fund&#8217;s manager and its affiliates are under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. You should not invest in the fund with the expectation that any such action will be taken. <br /><br />There is no assurance that the fund will meet its investment objective. <br /><br />The fund could underperform other short-term debt instruments or money market funds, or you could lose money, as a result of risks such as:<br /><br /><b>Market and interest rate risk.</b> There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.<br /><br /><b>Credit risk.</b> An issuer or obligor of a security held by the fund or a counterparty to a financial contract with the fund may default or its credit may be downgraded, or the value of assets underlying a security may decline.<br /><br /><b>Yield risk.</b> The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund&#8217;s expenses could absorb all or a significant portion of the fund&#8217;s income. If interest rates increase, the fund&#8217;s yield may not increase proportionately. For example, the fund&#8217;s manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund&#8217;s yield.<br /><br /><b>Risk of increase in expenses.</b> Your actual costs of investing in the fund may be higher than the expenses shown in &#8220;Annual fund operating expenses&#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease, or if a fee limitation is changed or terminated.<br /><br /><b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect.<br /><br /><b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations. <br /><br />These risks are discussed in more detail later in this Prospectus or in the statement of additional information (&#8220;SAI&#8221;). Performance Investment objective The fund&#8217;s investment objectives are to provide shareholders with high levels of current income exempt from federal income taxes, preservation of capital and liquidity.

Municipal securities include debt obligations issued by any of the 50 states and their political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in municipal securities and other structured securities such as variable rate demand obligations, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks.<br/><br/>Some municipal securities, such as general obligation issues, are backed by the issuer&#8217;s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself. The fund invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short-term rating category (or, with respect to not more than 3% of its total assets, in the second highest category) or, if not rated, are determined by the subadviser to be of equivalent quality. <br/><br/>Under normal circumstances, the fund may invest up to 20% of its assets in investments that pay interest that may be subject to regular federal income tax and/or the federal alternative minimum tax, although for temporary or defensive purposes, the fund may invest an unlimited amount in such securities. <br/><br/>As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. Certain risks An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. <br /><br /> Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the fund&#8217;s manager and its affiliates are under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. You should not invest in the fund with the expectation that any such action will be taken. <br /><br /> There is no assurance that the fund will meet its investment objective. <br /><br /> The fund could underperform other short-term municipal debt instruments or money market funds, or you could lose money, as a result of risks such as:<br /><br /> <b>Market and interest rate risk.</b> There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions.

For example, expense ratios may be higher than those shown if average net assets decrease, or if a fee limitation is changed or terminated.<br /><br /> <b>Tax risk.</b> The income on the fund&#8217;s municipal securities could become subject to federal income tax due to noncompliant conduct by issuers, unfavorable legislation or litigation or adverse interpretations by regulatory authorities.<br /><br /> <b>Structured securities risk.</b> The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the fund, or they may not receive tax, accounting or regulatory treatment anticipated by the fund.<br /><br /> <b>Risks associated with concentration in the banking industry.</b> The fund may invest a significant portion of its assets in municipal securities and interests in municipal securities that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.<br /><br /> <b>Risks relating to investments in municipal securities.</b> Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors.<br /><br /> <b>Prepayment or call risk.</b> Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security.<br /><br /> <b>Extension risk.</b> If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.<br /><br /> <b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect.<br /><br /> <b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations. <br /><br /> These risks are discussed in more detail later in this Prospectus or in the statement of additional information (&#8220;SAI&#8221;). <br /><br /> The fund is classified as &#8220;non-diversified,&#8221; which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. However, the fund intends to comply with the diversification requirements applicable to money market funds which limit the fund&#8217;s ability to invest in the obligations of a single issuer. 61 Performance The accompanying bar chart and table provide some indication of the risks of investing in the fund.

These securities may pay interest at fixed, floating or adjustable rates or may be issued at a discount. U.S. government obligations are not necessarily backed by the full faith and credit of the United States. Although the fund invests in U.S. government obligations, an investment in the fund is neither insured nor guaranteed by the U.S. government. <br /><br /> The fund invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short term rating category or, if not rated, are determined by the subadviser to be of equivalent quality. <br /><br /> As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. 0.0077 Certain risks Worst quarter An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. <br /><br /> Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the fund&#8217;s manager and its affiliates are under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. You should not invest in the fund with the expectation that any such action will be taken. <br /><br /> There is no assurance that the fund will meet its investment objective. <br /><br /> The fund could underperform other short-term debt instruments or money market funds, or you could lose money, as a result of risks such as:<br /><br /> <b>Market and interest rate risk.</b> There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.<br /><br /> <b>Credit risk.</b> An issuer or obligor of a security held by the fund or a counterparty to a financial contract with the fund may default or its credit may be downgraded, or the value of assets underlying a security may decline.<br /><br /> <b>Yield risk.</b> The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund&#8217;s expenses could absorb all or a significant portion of the fund&#8217;s income. If interest rates increase, the fund&#8217;s yield may not increase proportionately. For example, the fund&#8217;s manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund&#8217;s yield.<br /><br /> <b>Risk of increase in expenses.</b> Your actual costs of investing in the fund may be higher than the expenses shown in &#8220;Annual fund operating expenses&#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease, or if a fee limitation is changed or terminated.<br /><br /> <b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect.<br /><br /> <b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price.

Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. <br/><br/><b>Risks associated with focusing on investments in New York municipal securities.</b> The fund focuses its investments on New York municipal securities. The fund may be affected significantly by adverse economic, political or other events affecting New York municipal issuers. <br/><br/><b>Prepayment or call risk.</b> Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. <br/><br/><b>Extension risk.</b> If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer. <br/><br/><b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect. <br/><br/><b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price.

The fund is a money market fund which, under normal market conditions, invests at least 80% of its assets in short-term high quality municipal obligations and interests in municipal obligations that pay interest that is exempt from federal income tax, including the federal alternative minimum tax. Municipal securities include debt obligations issued by any of the 50 states and their political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in municipal securities and other structured securities such as variable rate demand obligations, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks. <br /><br /> Some municipal securities, such as general obligation issues, are backed by the issuer&#8217;s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself. The fund invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short-term rating category (or, with respect to not more than 3% of its total assets, in the second highest category) or, if not rated, are determined by the subadviser to be of equivalent quality. <br /><br /> Under normal circumstances, the fund may invest up to 20% of its assets in investments that pay interest that may be subject to regular federal income tax and/or the federal alternative minimum tax, although for temporary or defensive purposes, the fund may invest an unlimited amount in such securities. <br /><br /> As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future.

These municipal securities include debt obligations issued by California and its political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in California municipal securities and other structured securities such as variable rate demand obligations, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks. <br /><br />Some municipal securities, such as general obligation issues, are backed by the issuer&#8217;s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself. The fund invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short-term rating category (or, with respect to not more than 3% of its total assets, in the second highest category) or, if not rated, are determined by the subadviser to be of equivalent quality. <br /><br /> Under normal circumstances, the fund may invest up to 20% of its assets in investments that pay interest that may be subject to regular federal income tax, the federal alternative minimum tax and/or California state personal income tax, although for temporary or defensive purposes, the fund may invest an unlimited amount in such securities. <br /><br /> As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. <div style="display:none">~ http://www.leggmason.com/role/ScheduleAnnualFundOperatingExpensesWesternAssetGovernmentReservesClassN column period compact * ~</div> An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.<br /><br /> <b>Credit risk.</b> An issuer or obligor of a security held by the fund or a counterparty to a financial contract with the fund may default or its credit may be downgraded, or the value of assets underlying a security may decline.<br /><br /> <b>Yield risk.</b> The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund&#8217;s expenses could absorb all or a significant portion of the fund&#8217;s income. If interest rates increase, the fund&#8217;s yield may not increase proportionately. For example, the fund&#8217;s manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund&#8217;s yield.<br /><br /> <b>Risk of increase in expenses.</b> Your actual costs of investing in the fund may be higher than the expenses shown in &#8220;Annual fund operating expenses&#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease, or if a fee limitation is changed or terminated.<br /><br /> <b>Tax risk.</b> The income on the fund&#8217;s municipal securities could become subject to federal income tax or California state personal income tax due to noncompliant conduct by issuers, unfavorable legislation or litigation or adverse interpretations by regulatory authorities.<br /><br /> <b>Structured securities risk.</b> The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the fund, or they may not receive tax, accounting or regulatory treatment anticipated by the fund.<br /><br /> <b>Risks associated with concentration in the banking industry.</b> The fund may invest a significant portion of its assets in municipal securities and interests in municipal securities that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.<br /><br /> <b>Risks relating to investments in municipal securities.</b> Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors.<br /><br /> <b>Risks associated with focusing on investments in California municipal securities.</b> The fund focuses its investments on California municipal securities. The fund may be affected significantly by adverse economic, political or other events affecting California municipal issuers. The recent economic downturn has had a severe and negative impact on the State of California, causing a significant deterioration in California&#8217;s economic base. California&#8217;s economic and fiscal problems heighten the risks of investing in California municipal securities, including the risks of downgrades, market illiquidity and issuer defaults.<br /><br /> <b>Prepayment or call risk.</b> Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security.<br /><br /> <b>Extension risk.</b> If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.<br /><br /> <b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect.<br /><br /> <b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations. <br /><br /> These risks are discussed in more detail later in this Prospectus or in the statement of additional information (&#8220;SAI&#8221;). <br /><br /> The fund is classified as &#8220;non-diversified,&#8221; which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund.

For example, expense ratios may be higher than those shown if average net assets decrease, or if a fee limitation is changed or terminated.<br/><br/><b>Tax risk.</b> The income on the fund&#8217;s municipal securities could become subject to federal income tax or Connecticut state personal income tax due to noncompliant conduct by issuers, unfavorable legis-lation or litigation or adverse interpretations by regulatory authorities.<br/><br/><b>Structured securities risk.</b> The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the fund, or they may not receive tax, accounting or regulatory treatment anticipated by the fund.<br/><br/><b>Risks associated with concentration in the banking industry.</b> The fund may invest a significant portion of its assets in municipal securities and interests in municipal securities that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.<br/><br/><b>Risks relating to investments in municipal securities.</b> Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors.<br/><br/><b>Risks associated with focusing on investments in Connecticut municipal securities.</b> The fund focuses its investments on Connecticut municipal securities. The fund may be affected significantly by adverse economic, political or other events affecting Connecticut municipal issuers.<br/><br/><b>Prepayment or call risk.</b> Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security.<br/><br/><b>Extension risk.</b> If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.<br/><br/><b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect.<br/><br/><b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations.<br/><br/>These risks are discussed in more detail later in this Prospectus or in the statement of additional information (&#8220;SAI&#8221;).<br/><br/>The fund is classified as &#8220;non-diversified,&#8221; which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. However, the fund intends to comply with the diversification requirements applicable to money market funds which limit the fund&#8217;s ability to invest in the obligations of a single issuer. Performance Performance The accompanying bar chart and table provide some indication of the risks of investing in the fund.

These municipal securities include debt obligations issued by New York and its political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in New York municipal securities and other structured securities such as variable rate demand obligations, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks.<br/><br/>Some municipal securities, such as general obligation issues, are backed by the issuer&#8217;s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself. The fund invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short-term rating category (or, with respect to not more than 3% of its total assets, in the second highest category) or, if not rated, are determined by the subadviser to be of equivalent quality.<br/><br/>Under normal circumstances, the fund may invest up to 20% of its assets in investments that pay interest that may be subject to regular federal income tax, the federal alternative minimum tax and/or New York state and New York City personal income taxes, although for temporary or defensive purposes, the fund may invest an unlimited amount in such securities.<br/><br/>As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. Certain risks An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.<br/><br/>Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the fund&#8217;s manager and its affiliates are under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. You should not invest in the fund with the expectation that any such action will be taken.<br/><br/>There is no assurance that the fund will meet its investment objective.<br/><br/>The fund could underperform other short-term municipal debt instruments or money market funds, or you could lose money, as a result of risks such as:<br/><br/><b>Market and interest rate risk.</b> There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.<br/><br/><b>Credit risk.</b> An issuer or obligor of a security held by the fund or a counterparty to a financial contract with the fund may default or its credit may be downgraded, or the value of assets underlying a security may decline.<br/><br/><b>Yield risk.</b> The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund&#8217;s expenses could absorb all or a significant portion of the fund&#8217;s income. If interest rates increase, the fund&#8217;s yield may not increase proportionately. For example, the fund&#8217;s manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund&#8217;s yield.<br/><br/><b>Risk of increase in expenses.</b> Your actual costs of investing in the fund may be higher than the expenses shown in &#8220;Annual fund operating expenses&#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease, or if a fee limitation is changed or terminated.<br/><br/><b>Tax risk.</b> The income on the fund&#8217;s municipal securities could become subject to federal income tax or New York state and New York City personal income taxes due to noncompliant conduct by issuers, unfavorable legislation or litigation or adverse interpretations by regulatory authorities.<br/><br/><b>Structured securities risk.</b> The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the fund, or they may not receive tax, accounting or regulatory treatment anticipated by the fund.<br/><br/><b>Risks associated with concentration in the banking industry.</b> The fund may invest a significant portion of its assets in municipal securities and interests in municipal securities that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.<br/><br/><b>Risks relating to investments in municipal securities.</b> Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities.

These municipal securities include debt obligations issued by California and its political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in California municipal securities and other structured securities such as variable rate demand obligations, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks. <br/><br/>Some municipal securities, such as general obligation issues, are backed by the issuer&#8217;s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself. The fund invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short-term rating category (or, with respect to not more than 3% of its total assets, in the second highest category) or, if not rated, are determined by the subadviser to be of equivalent quality. <br/><br/>Under normal circumstances, the fund may invest up to 20% of its assets in investments that pay interest that may be subject to regular federal income tax, the federal alternative minimum tax and/or California state personal income tax, although for temporary or defensive purposes, the fund may invest an unlimited amount in such securities.<br/><br/>As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. Certain risks An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. <br/><br/> Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the fund&#8217;s manager and its affiliates are under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. You should not invest in the fund with the expectation that any such action will be taken. <br/><br/> There is no assurance that the fund will meet its investment objective. <br/><br/> The fund could underperform other short-term municipal debt instruments or money market funds, or you could lose money, as a result of risks such as: <br/><br/> <b>Market and interest rate risk.</b> There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. <br/><br/> <b>Credit risk.</b> An issuer or obligor of a security held by the fund or a counterparty to a financial contract with the fund may default or its credit may be downgraded, or the value of assets underlying a security may decline. <br/><br/> <b>Yield risk.</b> The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund&#8217;s expenses could absorb all or a significant portion of the fund&#8217;s income. If interest rates increase, the fund&#8217;s yield may not increase proportionately. For example, the fund&#8217;s manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund&#8217;s yield. <br/><br/> <b>Risk of increase in expenses.</b> Your actual costs of investing in the fund may be higher than the expenses shown in &#8220;Annual fund operating expenses&#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets are lower than estimated, or if a fee limitation is changed or terminated. <br/><br/> <b>Tax risk.</b> The income on the fund&#8217;s municipal securities could become subject to federal income tax or California state personal income tax due to noncompliant conduct by issuers, unfavorable legislation or litigation or adverse interpretations by regulatory authorities. <br/><br/> <b>Structured securities risk.</b> The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the fund, or they may not receive tax, accounting or regulatory treatment anticipated by the fund. <br/><br/> <b>Risks associated with concentration in the banking industry.</b> The fund may invest a significant portion of its assets in municipal securities and interests in municipal securities that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry. <br/><br/> <b>Risks relating to investments in municipal securities.</b> Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. <br/><br/> <b>Risks associated with focusing on investments in California municipal securities. </b> The fund focuses its investments on California municipal securities. The fund may be affected significantly by adverse economic, political or other events affecting California municipal issuers. The recent economic downturn has had a severe and negative impact on the State of California, causing a significant deterioration in California&#8217;s economic base. California&#8217;s economic and fiscal problems heighten the risks of investing in California municipal securities, including the risks of downgrades, market illiquidity and issuer defaults. <br/><br/> <b>Prepayment or call risk. </b> Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. <br/><br/> <b>Extension risk. </b> If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.<br/><br/> <b>Portfolio selection risk. </b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect. <br/><br/> <b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations. <br/><br/> These risks are discussed in more detail later in this Prospectus or in the statement of additional information (&#8220;SAI&#8221;). <br/><br/> The fund is classified as &#8220;non-diversified,&#8221; which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund.

Actual expenses may differ from estimates. December 31, 2014 Principal investment strategies The fund is a money market fund which, under normal market conditions, invests at least 80% of its assets in short-term high quality municipal obligations and interests in municipal obligations that pay interest that is exempt from federal income tax, including the federal alternative minimum tax, and Connecticut personal income tax. These municipal securities include debt obligations issued by Connecticut and its political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in Connecticut municipal securities and other structured securities such as variable rate demand obligations, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks.<br/><br/>Some municipal securities, such as general obligation issues, are backed by the issuer&#8217;s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself. The fund invests in securities that, at the time of purchase, are rated by one or more rating agencies in the highest short-term rating category (or, with respect to not more than 3% of its total assets, in the second highest category) or, if not rated, are determined by the subadviser to be of equivalent quality.<br/><br/>Under normal circumstances, the fund may invest up to 20% of its assets in investments that pay interest that may be subject to regular federal income tax, the federal alternative minimum tax and/or Connecticut state personal income tax, although for temporary or defensive purposes, the fund may invest an unlimited amount in such securities.<br/><br/>As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. Certain risks An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.<br/><br/>Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the fund&#8217;s manager and its affiliates are under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. You should not invest in the fund with the expectation that any such action will be taken.<br/><br/>There is no assurance that the fund will meet its investment objective.<br/><br/>The fund could underperform other short-term municipal debt instruments or money market funds, or you could lose money, as a result of risks such as:<br/><br/><b>Market and interest rate risk.</b> There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.<br/><br/><b>Credit risk.</b> An issuer or obligor of a security held by the fund or a counterparty to a financial contract with the fund may default or its credit may be downgraded, or the value of assets underlying a security may decline.<br/><br/><b>Yield risk.</b> The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund&#8217;s expenses could absorb all or a significant portion of the fund&#8217;s income. If interest rates increase, the fund&#8217;s yield may not increase proportionately. For example, the fund&#8217;s manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund&#8217;s yield.<br/><br/><b>Risk of increase in expenses.</b> Your actual costs of investing in the fund may be higher than the expenses shown in &#8220;Annual fund operating expenses&#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets are lower than estimated, or if a fee limitation is changed or terminated.<br/><br/><b>Tax risk.</b> The income on the fund&#8217;s municipal securities could become subject to federal income tax or Connecticut state personal income tax due to noncompliant conduct by issuers, unfavorable legislation or litigation or adverse interpretations by regulatory authorities.<br/><br/><b>Structured securities risk.</b> The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the fund, or they may not receive tax, accounting or regulatory treatment anticipated by the fund.<br/><br/><b>Risks associated with concentration in the banking industry.</b> The fund may invest a significant portion of its assets in municipal securities and interests in municipal securities that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.<br/><br/><b>Risks relating to investments in municipal securities.</b> Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors.<br/><br/><b>Risks associated with focusing on investments in Connecticut municipal securities.</b> The fund focuses its investments on Connecticut municipal securities. The fund may be affected significantly by adverse economic, political or other events affecting Connecticut municipal issuers.<br/><br/><b>Prepayment or call risk.</b> Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security.<br/><br/><b>Extension risk.</b> If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.<br/><br/><b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect.<br/><br/><b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations.<br/><br/>These risks are discussed in more detail later in this Prospectus or in the statement of additional information (&#8220;SAI&#8221;).<br/><br/>The fund is classified as &#8220;non-diversified,&#8221; which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. However, the fund intends to comply with the diversification requirements applicable to money market funds which limit the fund&#8217;s ability to invest in the obligations of a single issuer. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.

Fees and expenses of the fund December 31, 2014 LEGG MASON PARTNERS MONEY MARKET TRUST 2012-12-28 2012-12-28 2012-12-13 Western Asset Liquid Reserves Investment objective The fund&#8217;s investment objective is to provide shareholders with liquidity and as high a level of current income as is consistent with preservation of capital. Fees and expenses of the fund The accompanying table describes the fees and expenses that you may pay if you buy and hold shares of the fund. <b>Shareholder fees </b>(fees paid directly from your investment) <b>Annual fund operating expenses </b>(expenses that you pay each year as a percentage of the value of<br>your investment)<b> (%)</b> <b>Example </b> This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The information above reflects the direct expenses of the fund and its allocated share of expenses of Liquid Reserves Portfolio. Principal investment strategies The fund is a money market fund which invests in high quality, U.S. dollar-denominated short-term debt securities that, at the time of purchase, are rated by one or more rating agencies in the highest short term rating category or, if not rated, are determined by the subadviser to be of equivalent quality. <br/><br/>The fund may invest in all types of money market instruments, including bank obligations, commercial paper and asset-backed securities, structured investments, repurchase agreements and other short-term debt securities. These instruments may be issued or guaranteed by all types of issuers, including U.S. and foreign banks and other private issuers, the U.S. government or any of its agencies or instrumentalities, U.S. states and municipalities, or foreign governments. These securities may pay interest at fixed, floating or adjustable rates, or may be issued at a discount. The fund may invest without limit in bank obligations, such as certificates of deposit, fixed time deposits and bankers&#8217; acceptances. The fund generally limits its investments in foreign securities to U.S. dollar denominated obligations of issuers, including banks and foreign governments, located in the major industrialized countries, although with respect to bank obligations, the branches of the banks issuing the obligations may be located in The Bahamas or the Cayman Islands. <br/><br/>As a money market fund, the fund tries to maintain a share price of $1.00, and must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund&#8217;s subadviser or Board of Trustees (the &#8220;Board&#8221;) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase. Certain risks An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. <br/><br/>Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, &#8220;broken the buck,&#8221; which means that investors did not receive $1.00 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the fund&#8217;s manager and its affiliates are under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. You should not invest in the fund with the expectation that any such action will be taken. <br/><br/>There is no assurance that the fund will meet its investment objective. <br/><br/>The fund could underperform other short-term debt instruments or money market funds, or you could lose money, as a result of risks such as:<br/><br/><b>Market and interest rate risk.</b> There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.<br/><br/><b>Credit risk.</b> An issuer or obligor of a security held by the fund or a counterparty to a financial contract with the fund may default or its credit may be downgraded, or the value of assets underlying a security may decline.<br/><br/><b>Yield risk.</b> The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund&#8217;s expenses could absorb all or a significant portion of the fund&#8217;s income. If interest rates increase, the fund&#8217;s yield may not increase proportionately. For example, the fund&#8217;s manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund&#8217;s yield.<br/><br/><b>Risk of increase in expenses.</b> Your actual costs of investing in the fund may be higher than the expenses shown in &#8220;Annual fund operating expenses&#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease, or if a fee limitation is changed or terminated.<br/><br/><b>Structured securities risk.</b> The payment and credit qualities of structured securities derive from their underlying assets, and they may behave in ways not anticipated by the fund, or they may not receive tax, accounting or regulatory treatment anticipated by the fund.<br/><br/><b>Risks associated with concentration in the banking industry.</b> The fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.<br/><br/><b>Foreign investments risk.</b> The fund&#8217;s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the fund may invest may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the fund&#8217;s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability. Lack of information may also affect the value of these securities.<br/><br/><b>Prepayment or call risk.</b> Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security.<br/><br/><b>Extension risk.</b> If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.<br/><br/><b>Portfolio selection risk.</b> The value of your investment may decrease if the subadviser&#8217;s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or sector, or about interest rates generally, is incorrect.<br/><br/><b>Redemption risk.</b> The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations.<br/><br/>These risks are discussed in more detail later in this Prospectus or in the statement of additional information (&#8220;SAI&#8221;).
