LEGG MASON PARTNERS INSTITUTIONAL TRUST

As filed with the U.S. Securities and Exchange Commission on October 24, 2019

Beginning in January 2021, as permitted by regulations adopted by the Securities and Exchange Commission, the fund intends to no longer mail paper copies of the fund’s shareholder reports, unless you specifically request paper copies of the reports from the fund or from your Service Agent or financial intermediary (such as a broker-dealer or bank). Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.

If you already elected to receive shareholder reports electronically (“e-delivery”), you will not be affected by this change and you need not take any action. If you have not already elected e-delivery, you may elect to receive shareholder reports and other communications from the fund electronically by contacting your Service Agent or, if you are a direct shareholder with the fund, by calling 1-877-721-1926.

You may elect to receive all future reports in paper free of charge. If you invest through a Service Agent, you can contact your Service Agent to request that you continue to receive paper copies of your shareholder reports. That election will apply to all Legg Mason funds held in your account at that Service Agent. If you are a direct shareholder with the fund, you can call the fund at 1-877-721-1926, or write to the fund by regular mail at Legg Mason Funds, P.O. Box 9699, Providence, RI 02940-9699 or by express, certified or registered mail to Legg Mason Funds, 4400 Computer Drive, Westborough, MA 01581 to let the fund know you wish to continue receiving paper copies of your shareholder reports. That election will apply to all Legg Mason Funds held in your account held directly with the fund complex.

The Securities and Exchange Commission has not approved or disapproved these securities or determined whether this Prospectus is accurate or complete. Any statement to the contrary is a crime.

The fund seeks maximum current income to the extent consistent with preservation of capital and the maintenance of liquidity.

The accompanying table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

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 example assumes:

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The fund is a feeder fund that invests in securities through an underlying mutual fund, Government Portfolio, which has the same investment objective and strategies as the fund. This structure is sometimes known as a “master/feeder” structure.

The fund is a money market fund that invests exclusively in short-term U.S. government obligations, including U.S. Treasuries and securities issued or guaranteed by the U.S. government or its agencies, authorities, instrumentalities or sponsored entities and in repurchase agreements collateralized by government obligations. 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. The fund may also hold cash for cash management and defensive 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.

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.

As noted above, the fund invests exclusively in short-term U.S. government obligations and in repurchase agreements collateralized by government obligations. Therefore, the fund meets the requirement under Rule 2a-7 under the Investment Company Act of 1940, as amended, that a government money market fund invest at least 99.5% of its total assets in U.S. government obligations, cash, and/or repurchase agreements that are fully collateralized by U.S. government obligations or cash. In addition, the fund meets the requirement under Rule 35d-1 under the Investment Company Act of 1940, as amended, that a fund that includes the term “government” in its name invest, under normal circumstances, at least 80% of its net assets in U.S. government obligations and/or repurchase agreements that are collateralized by U.S. government obligations.

As a government money market fund, the fund tries to maintain a share price of $1.00. Under Rule 2a-7 of the Investment Company Act of 1940, as amended, the fund must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund’s subadviser or Board of Trustees (the “Board”) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase.

You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

If one or more money market funds were to incur a sizeable loss or impose fees on redemptions or suspend redemptions, there could be significant redemptions from money market funds in general, potentially driving the market prices of money market instruments down and adversely affecting market liquidity.

The fund does not currently intend to avail itself of the ability to impose “liquidity fees” and/or “gates” on fund redemptions, as permitted under Rule 2a-7. However, the Board reserves the right, with notice to shareholders, to change this policy, thereby permitting the fund to impose such fees and gates in the future.

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:

the fund’s securities fall, the value of your investment could decline. Market prices will generally go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term securities. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions from the fund.

Market events risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, investor sentiment and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, terrorism, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the fund’s investments may be negatively affected.

Credit risk. An issuer or other obligor (such as a party providing insurance or other credit enhancement) 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 perceived to be less creditworthy, or the value of assets underlying a security may decline, causing the value of your investment to decline. The fund could be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty.

Yield risk. The amount of income received by the fund will go up or down depending on variations in short-term interest rates, and when interest rates are very low the fund’s expenses could absorb all or a significant portion of the fund’s income. If interest rates increase, the fund’s yield may not increase proportionately, if for example, the fund’s manager discontinued any temporary voluntary fee limitation or recouped amounts previously waived and/or reimbursed.

Portfolio management risk. The value of your investment may decrease if the subadviser’s judgment about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, or about interest rates, is incorrect or does not produce the desired results, or if there are imperfections, errors or limitations in the tools and data used by the subadviser. In addition, the fund’s investment strategies or policies may change from time to time. Those changes may not lead to the results intended by the subadviser and could have an adverse effect on the value or performance of the fund.

Valuation risk. The sales price the fund could receive for any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. The fund’s ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of the fund’s investments involves subjective judgment.

Redemption risk. The fund may experience heavy redemptions 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’s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations.

Risk relating to investments by other funds. Other funds, including affiliated funds, may invest in the fund. From time to time, the fund may experience relatively large redemptions or investments from these funds as a result of their rebalancing their portfolios or for other reasons. In the event of such redemptions or investments, the fund could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

Cybersecurity risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information), or proprietary information, cause the fund, the manager, the subadviser and/or their service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions. A fund, the manager, and the subadviser have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund or the manager. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent any future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

These and other risks are discussed in more detail in the Prospectus or in the Statement of Additional Information.

The fund is newly offered and, therefore, does not have performance to report. Once the fund has a performance record of at least one calendar year, the fund’s performance will be included in its Prospectus. The fund will make updated performance information available at www.leggmason.com/moneymarketfunds (select fund and share class), or by calling the fund at 1-877-721-1926.

In general, you may purchase, redeem or exchange shares of the fund during fund business hours on any day on which both the New York Stock Exchange and the Federal Reserve Bank of New York are open for business, subject to certain exceptions.

The fund’s initial and subsequent investment minimums for Capital Shares and Premium Shares generally are set forth in the accompanying table:

Your Service Agent may impose different investment minimums. “Service Agents” are banks, brokers, dealers, insurance companies, investment advisers, financial consultants or advisers, mutual fund supermarkets and other financial intermediaries that have entered into an agreement with the distributor.

The fund normally calculates its net asset value as of each hour from 9:00 a.m. (Eastern time) until its close of business (normally 5:00 p.m. (Eastern time)) on each fund business day. The fund may close early under certain circumstances. For more information, please contact your financial intermediary, or contact the fund by phone (1-877-721-1926 or 1-203-703-6002).

The fund’s distributions are generally taxable as ordinary income or capital gains.

The fund’s related companies may pay Service Agents for the sale of fund shares, shareholder services and other purposes. These payments create a conflict of interest by influencing your Service Agent or its employees or associated persons to recommend the fund over another investment. Ask your financial adviser or salesperson or visit your Service Agent’s or salesperson’s website for more information.

The fund’s investment objective is to provide shareholders with liquidity and as high a level of current income as is consistent with preservation of capital.

The accompanying table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

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 example assumes:

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The fund is a feeder fund that invests in securities through an underlying mutual fund, Liquid Reserves Portfolio, which has the same investment objective and strategies as the fund. This structure is sometimes known as a “master/feeder” structure.

The fund is a money market fund that 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.

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’ acceptances. The fund may invest up to 25% of its assets in U.S. dollar-denominated obligations of non-U.S. banks. 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.

Under Rule 2a-7 of the Investment Company Act of 1940, as amended, the fund must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments. Where required by these rules, the fund’s subadviser or Board of Trustees (the “Board”) will decide whether a security should be held or sold in the event of credit downgrades or certain other events occurring after purchase.

The fund sells and redeems its shares at prices based on the current market value of the securities it holds. Therefore, the share price of the fund will fluctuate along with changes in the market-based value of fund assets. Because the share price of the fund fluctuates, it has what is called a “floating net asset value” or “floating NAV”.

You could lose money by investing in the fund. Because the share price of the fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

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:

Market and interest rate risk. The market prices of the fund’s securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, tariffs and trade disruptions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. If the market prices of the fund’s securities fall, the value of your investment will decline. The value of your investment will generally go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term securities. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions from the fund.

Structured securities risk. 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.

Risks associated with concentration in the banking industry. 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 banks and the financial services sector worldwide. Changes in money market and general economic conditions, governmental policies and applicable regulations may adversely affect banks’ ability to obtain funds at reasonable costs and to finance their lending and other operations, including by limiting the loans they may make and the interest rates and fees they charge. Banking losses also result from defaults by borrowers, data breaches, certain bank activities such as mortgage banking and foreign exchange practices, and investments in derivatives.

Foreign investments risk. The fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk as compared to investments in U.S. securities or issuers with predominantly domestic exposure, such as less liquid, less transparent, less regulated and more volatile markets. The value of the fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, reduction of government or central bank support, inadequate accounting standards, lack of information and political, economic, financial or social instability.

Repurchase agreements risk. Repurchase agreements could involve certain risks in the event of default or insolvency of the seller, including losses and possible delays or restrictions upon the fund’s ability to dispose of the underlying securities. To the extent that, in the meantime, the value of the securities that the fund has purchased has decreased, the fund could experience a loss.

Illiquidity risk. The fund may make investments that are illiquid or that become illiquid after purchase. The liquidity and value of investments can deteriorate rapidly, and they may become difficult or impossible to sell, particularly during times of market turmoil. Illiquid investments may also be difficult to value. Markets may become illiquid when, for instance, there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. If the fund is forced to sell an illiquid investment to meet redemption requests or other cash needs, the fund may be forced to sell at a loss. If Premier Institutional Liquid Reserves’ weekly liquid assets fall below certain designated thresholds, Premier Institutional Liquid Reserves may impose a fee of up to 2% on redemptions from the fund or temporarily restrict redemptions from the fund for up to 10 business days in any given 90-day period.

Redemption risk. The fund may experience heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of your investment to decline. In addition, the fund may impose a fee or suspend redemptions under certain conditions.

These and other risks are discussed in more detail in the Prospectus or in the Statement of Additional Information.

In general, you may purchase or redeem shares of the fund during fund business hours on any day on which both the New York Stock Exchange and the Federal Reserve Bank of New York are open for business, subject to certain exceptions.

The fund’s initial and subsequent investment minimums for Capital Shares generally are set forth in the accompanying table:

The fund normally calculates its net asset value as of 8:00 a.m., 12:00 p.m. and 3:00 p.m. (Eastern time) on each fund business day. The fund may close early under certain circumstances. For more information, please contact your financial intermediary, or contact the fund by phone (1-877-721-1926 or 1-203-703-6002).

The fund may impose a fee of up to 2% on redemptions from the fund or temporarily restrict redemptions from the fund for up to 10 business days in any given 90 day period in the event that the fund’s weekly liquid assets fall below certain designated thresholds. Any announcement regarding the imposition of a liquidity fee or redemption gate, or the termination of a liquidity fee or a redemption gate, will be available at the fund’s website, https://www.leggmason.com/en-us/products/money-markets/western-asset-premier-institutional-liquid-reserves.html, and will be filed with the Securities and Exchange Commission.

The fund’s distributions are generally taxable as ordinary income or capital gains.

The fund’s investment objective is to provide shareholders with liquidity and as high a level of current income from U.S. government obligations as is consistent with preservation of capital.

The fund is a feeder fund that invests in securities through an underlying mutual fund, U.S. Treasury Reserves Portfolio, which has the same investment objective and strategies as the fund. This structure is sometimes known as a “master/feeder” structure.

The fund is a money market fund that invests all of its assets in direct obligations of the U.S. Treasury. Direct obligations of the U.S. Treasury include U.S. Treasury bills, notes and bonds; STRIPS, which are individual interest and principal components of eligible Treasury notes and bonds that are traded as separate securities; and TIPS, which are inflation-protected securities issued by the U.S. Treasury, the principal of which increases with inflation and decreases with deflation, as measured by the Consumer Price Index. The fund will not enter into repurchase agreements. The fund may also hold cash for cash management and defensive 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.

As noted above, the fund invests all of its assets in direct obligations of the U.S. Treasury. Therefore, the fund meets the requirement under Rule 2a-7 under the Investment Company Act of 1940, as amended, that a government money market fund invest at least 99.5% of its total assets in U.S. government obligations, cash, and/or repurchase agreements that are fully collateralized by U.S. government obligations or cash. In addition, the fund meets the requirement under Rule 35d-1 under the Investment Company Act of 1940, as amended, that a fund that includes the term “U.S. Treasury” in its name invest, under normal circumstances, at least 80% of its net assets in U.S. Treasury obligations.

The fund may close early under certain circumstances. For more information, please contact your financial intermediary, or contact the fund by phone (1-877-721-1926 or 1-203-703-6002).

The fund’s distributions are generally taxable as ordinary income or capital gains.

Each fund is a money market fund. Under Rule 2a-7 of the Investment Company Act of 1940, as amended, money market funds must follow strict rules about the quality, liquidity, diversification, maturity and other features of securities they purchase. Western Asset Premier Institutional Liquid Reserves (“Premier Institutional Liquid Reserves”) sells and redeems its shares at prices based on the current market value of the securities it holds. Because the share price of Premier Institutional Liquid Reserves will fluctuate along with changes in the market-based value of fund assets, it has what is called a “floating net asset value” or “floating NAV”. Each of Western Asset Premier Institutional Government Reserves (“Premier Institutional Government Reserves”) and Western Asset Premier Institutional U.S. Treasury Reserves (“Premier Institutional U.S. Treasury Reserves”) tries to maintain a share price of $1.00 while paying income to shareholders. However, no money market fund guarantees that you will receive your money back.

Premier Institutional Government Reserves’ investment objective is to seek maximum current income to the extent consistent with preservation of capital and maintenance of liquidity. Premier Institutional Liquid Reserves’ investment objective is to provide shareholders with liquidity and as high a level of current income as is consistent with preservation of capital. Premier Institutional U.S. Treasury Reserves’ investment objective is to provide shareholders with liquidity and as high a level of current income from U.S. government obligations as is consistent with preservation of capital. Each fund’s investment objective may be changed by the Board of Trustees (the “Board”) without shareholder approval and on notice to shareholders.

Premier Institutional Government Reserves invests all of its assets in U.S. government obligations and in repurchase agreements secured by such obligations. Premier Institutional U.S. Treasury Reserves invests all of its assets in direct obligations of the U.S. Treasury. Shareholders of each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves will be provided with 60 days’ notice before any change in a fund’s policy to invest at least 80% of its net assets plus any borrowings for investment purposes in the particular type of investment suggested by its name. Premier Institutional Liquid Reserves 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.

Each fund’s investment strategies and policies may be changed from time to time without shareholder approval, unless specifically stated otherwise in this Prospectus or in the Statement of Additional Information (“SAI”).

Premier Institutional U.S. Treasury Reserves may invest only in direct obligations of the U.S. Treasury. Each of Premier Institutional Government Reserves and Premier Institutional Liquid Reserves 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. In addition, each security, at the time of purchase by the fund, has been determined by the subadviser to present minimal credit risk. Where required by applicable rules, the fund’s subadviser or Board will decide whether a security should be held or sold in the event of certain credit events occurring after purchase.

Each fund invests in securities that, at the time of purchase, are treated under applicable regulations as having remaining maturities of 397 days or less. For example, in determining the remaining maturity of a security for the purposes of these regulations, features such as a floating or variable rate of interest or a demand feature may be taken into account under some circumstances. Each fund maintains a dollar weighted average maturity of not more than 60 days. In addition, each fund maintains a dollar weighted average life of not more than 120 days. Where required by applicable rules, if, after purchase, payment upon maturity does not occur or the maturity on a security is extended, a fund’s subadviser or Board will decide whether the security should be held or sold.

Each fund must follow strict rules with respect to the liquidity of its portfolio securities including daily and weekly liquidity requirements. In addition, a fund may not purchase illiquid securities if, as a result of the acquisition, more than 5% of the fund’s total assets would be invested in illiquid securities. Illiquid securities are those that, as determined by the subadviser, may not be disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by a fund. Securities that are deemed liquid at the time of purchase by a fund may become illiquid following purchase. If Premier Institutional Liquid Reserves’ weekly liquid assets fall below certain designated thresholds, Premier Institutional Liquid Reserves may impose a fee of up to 2% on redemptions from the fund or temporarily restrict redemptions from the fund for up to 10 business days in any given 90-day period.

demand securities (where the interest rate is reset periodically and the holder may demand payment from the issuer or another obligor at any time), preferred shares, fixed-term obligations, commercial paper (short-term unsecured debt), asset-backed commercial paper, other asset-backed securities and repurchase agreements. Asset-backed commercial paper refers to a debt security with an original term to maturity of up to 270 days that may be backed by consumer loans or other types of receivables. Payments due on asset-backed commercial paper are supported by cash flows from underlying assets, or one or more liquidity or credit support providers, or both.

U.S. Treasury obligations are direct debt obligations issued by the U.S. government. Treasury bills, with maturities normally from 4 weeks to 52 weeks, are typically issued at a discount as they pay interest only upon maturity. Treasury bills are non-callable. Treasury notes have a maturity between two and ten years and typically pay interest semi-annually, while Treasury bonds have a maturity of over ten years and pay interest semi-annually. Treasuries also include STRIPS, TIPS and FRNs. STRIPS are Treasury obligations with separately traded principal and interest component parts that are transferable through the federal book-entry system. Because payments on STRIPS are made only at maturity, during periods of changing interest rates, STRIPS may be more volatile than unstripped U.S. Treasury obligations with comparable maturities. TIPS are Treasury Inflation-Protected Securities, the principal of which increases with inflation and decreases with deflation, as measured by the U.S. Consumer Price Index. At maturity, a TIPS holder is entitled to the adjusted principal or original principal, whichever is greater. TIPS pay interest twice a year, at a fixed rate. The rate is applied to the adjusted principal; so, like the principal, interest payments rise with inflation and fall with deflation. However, because the interest rate is fixed, TIPS may lose value when market interest rates increase, particularly during periods of low inflation. FRNs are newly introduced floating rate notes that are indexed to the most recent 13-week Treasury bill auction High Rate, and which pay interest quarterly. U.S. Treasury obligations typically offer lower interest rates than other obligations.

U.S. government obligations-Premier Institutional Government Reserves and Premier Institutional Liquid Reserves only

U.S. government obligations include U.S. Treasury obligations and other obligations of, or guaranteed by, the U.S. government, its agencies or government-sponsored entities. Although the U.S. government guarantees principal and interest payments on securities issued by the U.S. government and some of its agencies, such as securities issued by the U.S. Government National Mortgage Association (“Ginnie Mae”), this guarantee does not apply to losses resulting from declines in the market value of these securities. U.S. government obligations include zero coupon securities that make payments of interest and principal only upon maturity and which therefore tend to be subject to greater volatility than interest bearing securities with comparable maturities.

Some of the U.S. government securities that a fund may hold are not guaranteed or backed by the full faith and credit of the U.S. government, such as those issued by Fannie Mae (formally known as the Federal National Mortgage Association) and Freddie Mac (formally known as the Federal Home Loan Mortgage Corporation). The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government.

Structured instruments in which a fund invests are specifically structured so that they are eligible for purchase by money market funds, including securities that have demand, tender or put features, or interest rate reset features. Structured instruments may take the form of participation interests or receipts in underlying securities or other assets, and in some cases are backed by a financial institution serving as a liquidity provider. Some of these instruments may have a feature which substitutes a floating or variable interest rate for the fixed interest rate on an underlying security. The payment and credit qualities of these instruments derive from the underlying assets embedded in the structure.

Structured securities include variable rate demand instruments and participation interests that are backed by underlying municipal or other securities. Variable rate demand instruments require the issuer or a third party, such as a bank, insurer or broker/dealer, to repurchase the security for its face value upon demand and typically have interest rates that reset on a daily or weekly basis. In a participation interest, a bank or other financial institution sells undivided interests in a municipal or other security it owns. Participation interests may be supported by a bank letter of credit or guarantee. The interest rate generally is adjusted periodically, and the holder can sell the interests back to the issuer after a specified notice period.

Asset-backed securities represent participations in, or are secured by and payable from, assets such as installment sales or loan contracts, leases, credit card receivables and other categories of receivables.

Municipal securities include debt obligations issued by any of the 50 U.S. states or their political subdivisions, agencies and public authorities, certain other U.S. governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers, participation or other interests in these securities and other structured securities. Although municipal securities are issued by qualifying issuers, payments of principal and interest on municipal securities may be derived solely from revenues from certain facilities, mortgages or private industries, and may not be backed by the issuers themselves. These securities include participation or other interests in municipal securities issued or backed by banks, insurance companies and other financial institutions.

Municipal securities include general obligation bonds, revenue bonds, housing authority bonds, private activity bonds, industrial development bonds, residual interest bonds, tender option bonds, tax and revenue anticipation notes, bond anticipation notes, tax-exempt commercial paper, municipal leases, participation certificates and custodial receipts. General obligation bonds are backed by the full faith and credit of the issuing entity. Revenue bonds are typically used to fund public works projects, such as toll roads, airports and transportation facilities, that are expected to produce income sufficient to make the payments on the bonds, since they are not backed by the full taxing power of the municipality. Housing authority bonds are used primarily to fund low to middle income residential projects and may be backed by the payments made on the underlying mortgages. Tax and revenue anticipation notes are generally issued in order to finance short-term cash needs or, occasionally, to finance construction. Tax and revenue anticipation notes are expected to be repaid from taxes or designated revenues in the related fiscal period, and they may or may not be general obligations of the issuing entity. Bond anticipation notes are issued with the expectation that their principal and interest will be paid out of proceeds from renewal notes or bonds and may be issued to finance such items as land acquisition, facility acquisition and/or construction and capital improvement projects. Some of these securities may have stated final maturities of more than 397 days but have demand features that entitle the fund to receive the principal amount of the securities either at any time or at specified intervals.

Municipal securities include municipal lease obligations, which are undivided interests issued by a state or municipality in a lease or installment purchase contract which generally relates to equipment or facilities. In some cases, payments under municipal leases do not have to be made unless money is specifically approved for that purpose by an appropriate legislative body.

The fund may invest without limit in obligations of U.S. banks and up to 25% of its assets in U.S. dollar-denominated obligations of non-U.S. banks. Obligations of non-U.S. branches of U.S. banks and U.S. branches of non-U.S. banks may be considered obligations of U.S. banks if they meet certain requirements. Bank obligations include bank notes, certificates of deposit, time deposits, banker’s acceptances, commercial paper and other similar obligations. They also include Eurodollar and Yankee obligations, such as certificates of deposit issued in U.S. dollars by non-U.S. banks and non-U.S. branches of U.S. banks. Bank obligations also include participation interests in municipal securities issued and/or backed by banks, variable rate demand notes, and other obligations that have credit support or liquidity features provided by banks.

When-issued securities, delayed delivery, to be announced and forward commitment transactions

Each fund may purchase securities under arrangements (called when-issued, delayed delivery, to be announced or forward commitment basis) where the securities will not be delivered or paid for immediately. A fund will set aside assets to pay for these securities at the time of the agreement. Such transactions involve a risk of loss, for example, if the value of the securities declines prior to the settlement date or if the assets set aside to pay for these securities decline in value prior to the settlement date. Therefore, these transactions may have a leveraging effect on a fund, making the value of an investment in the fund more volatile and increasing the fund’s overall investment exposure. Typically, no income accrues on securities a fund has committed to purchase prior to the time delivery of the securities is made, although the fund may earn income on securities it has set aside to cover these positions. Recently finalized rules of the Financial Industry Regulatory Authority (“FINRA”) impose mandatory margin requirements for certain types of when-issued, to be announced or forward commitment transactions, with limited exceptions. Such transactions historically have not been required to be collateralized, and mandatory collateralization could increase the cost of such transactions and impose added operational complexity.

Repurchase agreements-Premier Institutional Government Reserves and Premier Institutional Liquid Reserves Only

In a repurchase agreement, a fund purchases securities from a counterparty, upon the agreement of the counterparty to repurchase the securities from the fund at a later date, and at a specified price, which is typically higher than the purchase price paid by the fund. The securities purchased serve as the fund’s collateral for the obligation of the counterparty to repurchase the securities. If the counterparty does not repurchase the securities, the fund is entitled to sell the securities, but the fund may not be able to sell them for the price at which they were purchased, thus causing a loss. Additionally, if the counterparty becomes insolvent, there is some risk that the fund will not have a right to the securities, or the immediate right to sell the securities.

Reverse repurchase agreements and other borrowings-Premier Institutional Government Reserves and Premier Institutional Liquid Reserves Only

Each fund may borrow money as a means of raising money to satisfy redemption requests or for other temporary or emergency purposes by entering into reverse repurchase agreements or other borrowing transactions. In a reverse repurchase agreement, a fund sells securities to a counterparty, in return for cash, and the fund agrees to repurchase the securities at a later date and for a higher price, representing the cost to the fund for the money borrowed. Although the funds do not intend to use these transactions for leveraging purposes, reverse repurchase agreements and other borrowing transactions may make the value of an investment in a fund more volatile and increase the fund’s overall investment exposure.

Variable rate demand notes (VRDNs) and other similar obligations are typically long term instruments issued with a floating rate of interest by municipalities or other issuers. The interest rate usually resets every one to seven days, based on a published interest rate index. Investors typically may resell a VRDN to a third-party financial intermediary serving as a remarketing agent on up to seven days’ notice. A VRDN may be supported by a liquidity facility or a letter of credit. These features permit the VRDN to be treated by a fund as a short-term instrument. Investments in VRDNs

involve credit risk with respect to the issuer as well as with respect to the financial institutions providing remarketing, liquidity or credit support. In addition, failures or defaults by one or more of those entities could result in a fund holding a long-term fixed rate illiquid investment.

Premier Institutional U.S. Treasury Reserves may invest only in direct obligations of the U.S. Treasury. Premier Institutional Government Reserves invests exclusively in short-term U.S. government obligations and repurchase agreements collateralized by government obligations. Each fund may also hold cash uninvested for cash management and defensive purposes. In the event of unusual circumstances when obligations in which a fund invests are not available for purchase, or when the subadviser deems it appropriate, including during periods when the interest rate on newly-issued securities is extremely low, or where no interest is paid at all, each fund may, without limit, hold cash uninvested.

If a fund holds cash uninvested, the fund may be subject to risk with respect to the depository institution holding the cash. In addition, a fund will not earn income on those assets.

If a fund takes a temporary defensive position, it will be more difficult for the fund to achieve its investment objective.

Although the subadviser has the ability to take defensive positions, it may choose not to do so for a variety of reasons, even during volatile market conditions.

Each fund may also use other strategies and invest in other investments that are described, along with their risks, in the Statement of Additional Information (“SAI”). However, a fund might not use all of the strategies and techniques or invest in all of the types of investments described in this Prospectus or in the SAI.

Because the funds are subject to maturity limitations on the investments they may purchase, many of their investments are held until maturity. The subadviser may sell a security before maturity when it is necessary to do so to meet redemption requests or regulatory requirements. The subadviser may also sell a security if the subadviser believes the issuer is no longer as creditworthy, or in order to adjust the average weighted maturity of a fund’s portfolio (for example, to reflect changes in the subadviser’s expectations concerning interest rates), or when the subadviser believes there is superior value in other market sectors or industries.

Each fund does not invest directly in securities but instead invests through an underlying mutual fund having the same investment objective and strategies under a master/feeder structure. Unless otherwise indicated, references to the fund, called a feeder fund, in this Prospectus include the underlying master fund. Each fund may stop investing in its corresponding underlying fund at any time, and will do so if a fund’s Board believes it to be in the best interests of the fund’s shareholders. Each fund could then invest in one or more other mutual funds or pooled investment vehicles, or could invest directly in securities. Investors should note that other feeder funds may invest in the same underlying mutual fund. Those other funds may have lower fees and/or expenses, and correspondingly higher performance, than your fund. In addition, large purchases or redemptions by one feeder fund could negatively affect the performance of other feeder funds that invest in the same master fund.

Following is more information on the principal risks summarized above and additional risks of investing in the funds.

You could lose money by investing in a fund. Although each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. Because the share price of Premier Institutional Liquid Reserves will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. Premier Institutional Liquid Reserves may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in a fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Each fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

Neither Premier Institutional Government Reserves nor Premier Institutional U.S. Treasury Reserves currently intends to avail itself of the ability to impose “liquidity fees” and/or “gates” on fund redemptions, as permitted under Rule 2a-7. However, the Board reserves the right, with notice to shareholders, to change this policy, thereby permitting a fund to impose such fees and gates in the future.

Each fund could underperform other short-term debt instruments or money market funds, or you could lose money, as a result of risks such as:

Market and interest rate risk (Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves). The market prices of a fund’s securities may go up or down, sometimes rapidly or unpredictably. While each fund seeks to maintain a $1.00 share price, if the market prices of the securities owned by a fund fall, the value of your investment in the fund could decline. Market prices may fall due to general market conditions, such as real or perceived adverse economic or political conditions, tariffs and trade disruptions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. Changes in market conditions will not typically have the same impact on all types of securities. The market price of a security may also fall due to specific conditions that affect a particular sector of the securities market or a particular issuer.

The market prices of securities may fluctuate significantly when interest rates change. When interest rates rise, the market price of fixed income securities generally goes down. Generally, the longer the maturity of a fixed income security, the greater the impact of a rise in interest rates on the security’s market price. Moreover, securities can change in value in response to other factors, such as credit risk. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. When interest rates go down, a fund’s yield will decline. Also, when interest rates decline, investments made by a fund may pay a lower interest rate, which would reduce the income received by the fund.

Market and interest rate risk (Premier Institutional Liquid Reserves). The market prices of the fund’s securities may go up or down, sometimes rapidly or unpredictably. If the market prices of the fund’s securities fall, the value of your investment in the fund will decline. The market price of a security may fall due to general market conditions, such as real or perceived adverse economic or political conditions, tariffs and trade disruptions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets or adverse investor sentiment. Changes in market conditions will not typically have the same impact on all types of securities. The market price of a security may also fall due to specific conditions that affect a particular sector of the securities market or a particular issuer. Your fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of fund dividends and distributions.

The market prices of securities may fluctuate significantly when interest rates change. When interest rates rise, the value of fixed income securities, and therefore the value of your investment in the fund, generally goes down. Generally, the longer the maturity or duration of a fixed income security, the greater the impact of a rise in interest rates on the security’s market price. However, calculations of duration and maturity may be based on estimates and may not reliably predict a security’s price sensitivity to changes in interest rates. Moreover, securities can change in value in response to other factors, such as credit risk. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. When interest rates go down, the fund’s yield will decline. Also, when interest rates decline, investments made by the fund may pay a lower interest rate, which would reduce the income received by the fund.

Market events risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, investor sentiment and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, terrorism, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not a fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of a fund’s investments may be negatively affected.

Credit risk. An issuer or other obligor (such as a party providing insurance or other credit enhancement) may fail to make the required payments on securities held by a fund. Debt securities also go up or down in value based on the perceived creditworthiness of issuers or other obligors. If an obligor for a security held by a fund fails to pay, otherwise defaults or is perceived to be less creditworthy, a security’s credit rating is downgraded, which could happen rapidly, or the credit quality or value of any underlying assets declines, the value of your investment in the fund could decline significantly, particularly in certain market environments. If a single entity provides credit enhancement to more than one of a fund’s investments, the adverse effects resulting from the downgrade or default of that entity’s credit will increase the adverse effects on the fund. If a fund enters into a financial contract (such as a repurchase agreement or reverse repurchase agreement) the fund will be subject to the credit risk presented by the counterparty. In addition, a fund may incur expenses in an effort to protect the fund’s interests or to enforce its rights or may be hindered or delayed in exercising those rights.

Although a fund’s investments may be treated as short-term securities for the purposes of meeting regulatory maturity limitations, the actual maturity of a security may be longer, and the security’s value may decline on the basis of perceived longer term credit risk of the issuer.

Upon the occurrence of certain triggering events or defaults on a security held by a fund, or if the subadviser believes that an obligor of such a security may have difficulty meeting its obligations, the fund may obtain a new or restructured security or underlying assets. In that case, a fund may become the holder of securities or assets that it could not purchase or might not otherwise hold (for example, because they are of lower quality or

are subordinated to other obligations of the issuer) at a time when those assets may be difficult to sell or can be sold only at a loss. Any of these events may cause you to lose money.

Yield risk. The funds invest in short-term money market instruments. As a result, the amount of income received by a fund will go up or down depending on variations in short-term interest rates. Investing in high quality, short-term instruments may result in a lower yield (the income on your investment) than investing in lower quality or longer-term instruments. When interest rates are very low, a fund’s expenses could absorb all or a significant portion of the fund’s income, and, if a fund’s expenses exceed the fund’s income, each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves may be unable to maintain its $1.00 share price and the price of Premier Institutional Liquid Reserves shares may fall. If interest rates increase, a fund’s yield may not increase proportionately. For example, the funds’ manager may discontinue any temporary voluntary fee limitation or recoup amounts previously waived and/or reimbursed.

A money market fund is also required to maintain liquidity levels based on the characteristics and anticipated liquidity needs of its shareholders. A fund with greater liquidity needs may have a lower yield than money market funds with a different shareholder base. Recently adopted requirements for money market funds may have a negative effect on a fund’s yield.

Risk of increase in expenses. Your actual costs of investing in a fund may be higher than the expenses shown in “Annual fund operating expenses” for a variety of reasons. For example, expenses may be higher if a fund’s average net assets decrease, as a result of redemptions or otherwise, or if a fee limitation is changed or terminated.

Prepayment or call risk (Premier Institutional Government Reserves and Premier Institutional Liquid Reserves). Many issuers have a right to prepay their securities. Issuers may be more likely to prepay their securities if interest rates fall. If this happens, a 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 prepaid securities.

Extension risk (Premier Institutional Government Reserves and Premier Institutional Liquid Reserves). 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.

Structured securities risk (Premier Institutional Liquid Reserves). The value of a structured security depends on the value of the underlying assets and the terms of the particular security. Investment by a fund in certain structured securities may have the effect of increasing the fund’s exposure to interest rate, market or credit risk, even if they are not primarily intended for these purposes. Structured securities may behave in ways not anticipated by the fund, and they raise certain tax, legal, regulatory and accounting issues that may not be presented by direct investments in the underlying assets. These issues could be resolved in a manner that could hurt the performance of the fund.

Risks associated with concentration in the banking industry (Premier Institutional Liquid Reserves). 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. Such investments are particularly susceptible to adverse events affecting banks and the financial services sector worldwide. Banks depend upon being able to obtain funds at reasonable costs and upon liquidity in the capital and credit markets to finance their lending and other operations. This makes them sensitive to changes in interest rates, money market and general economic conditions. Banks are highly regulated. Decisions by regulators may limit the loans banks make and the interest rates and fees they charge, and may reduce bank profitability. A bank’s borrowers’ inability or failure to repay the bank will adversely affect the bank’s financial situation. In the past, banks have been particularly hard hit by problems in the real estate industry including defaults by borrowers and litigation relating to mortgage banking practices. Other bank activities such as investments in derivatives and foreign exchange practices also have caused losses to banks. Governmental entities have in the past provided support to certain financial institutions, but there is no assurance they will do so in the future. Some of the entities backing fund investments may be non-U.S. institutions and, therefore, an investment in the fund may involve non-U.S. investments risk. Like other companies in the financial services sector, banks are also susceptible to data breaches.

Asset-backed securities risk (Premier Institutional Liquid Reserves). The value of asset-backed securities may be affected by changes in credit quality or value of the assets that support the securities as well as by changes in the credit risk of the servicing agent for the pool, the originator of the loans or receivables or the financial institution providing credit support, if any. In addition, the ability of an issuer of asset-backed securities to enforce its security interest in the underlying assets or to otherwise recover from the underlying obligor in the event of default may be limited and the liquidation value of the underlying assets may be inadequate to pay any unpaid principal or interest. Asset-backed securities are also sensitive to changes in interest rates which may increase prepayments or extend the duration of the securities.

Risks relating to investments in municipal securities (Premier Institutional Liquid Reserves). Issuers of municipal securities tend to derive a significant portion of their revenue from taxes, particularly property and income taxes, and decreases in personal income levels and property values and other unfavorable economic factors, such as a general economic recession, adversely affect municipal securities. Municipal issuers may also be adversely affected by rising health care costs, increasing unfunded pension liabilities and by the phasing out of U.S. federal programs providing financial support. Where municipal securities are issued to finance particular projects, such as those relating to education, health care, transportation, and utilities, issuers often depend on revenues from those projects to make principal and interest payments. Adverse conditions and developments in those sectors can result in lower revenues to issuers of municipal securities, potentially resulting in defaults, and can also have an adverse effect on the broader municipal securities market.

There may be less public information available on municipal issuers or projects than other issuers, and valuing municipal securities may be more difficult. In addition, the secondary market for municipal securities is less well developed and may have lower liquidity as compared to other markets,

and dealers may be less willing to offer and sell municipal securities in times of market turbulence. Changes in the financial condition of one or more individual municipal issuers (or one or more insurers of municipal issuers), or one or more defaults by municipal issuers or insurers, can adversely affect liquidity and valuations in the overall market for municipal securities. The value of municipal securities can also be adversely affected by regulatory and political developments affecting the ability of municipal issuers to pay interest or repay principal, actual or anticipated tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. In the past, a number of municipal issuers have defaulted on obligations, were downgraded or commenced insolvency proceedings. Financial difficulties of municipal issuers may experience a resurgence, particularly in the event of economic or market turmoil or a recession.

Foreign investments risk (Premier Institutional Liquid Reserves). A fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk as compared to investment in U.S. securities or issuers with predominantly domestic exposure, such as less liquid, less regulated, less transparent and more volatile markets. The value of a fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, tariffs and trade disputes, reduction of government or central bank support, inadequate accounting standards, lack of information and political, economic, financial or social instability. Foreign investments may also be adversely affected by U.S. government or international economic sanctions, which could eliminate the value of an investment.

The value of a fund’s foreign investments may also be affected by foreign tax laws, special U.S. tax considerations and restrictions on receiving the investment proceeds from a foreign country. Dividends or interest on, or proceeds from the sale or disposition of, foreign securities may be subject to non-U.S. withholding or other taxes.

It may be difficult for a fund to pursue claims against a foreign issuer or other parties in the courts of a foreign country. Some securities issued by non-U.S. governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of such governments. Even where a security is backed by the full faith and credit of a government, it may be difficult for a fund to pursue its rights against the government. In the past, some non-U.S. governments have defaulted on principal and interest payments.

In certain foreign markets, settlement and clearance of trades may experience delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments. Settlement of trades in these markets can take longer than in other markets and the fund may not receive its proceeds from the sale of certain securities for an extended period (possibly several weeks or even longer) due to, among other factors, low trading volumes and volatile prices. The custody or holding of securities, cash and other assets by local banks, agents and depositories in securities markets outside the United States may entail additional risks. Governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets, and thus may be subject to limited or no government oversight. In extreme cases, the fund’s securities may be misappropriated or the fund may be unable to sell its securities. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Portfolio management risk. The value of your investment may decrease if the subadviser’s judgment about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, or about interest rates, is incorrect or does not produce the desired results, or if there are imperfections, errors or limitations in the tools and data used by the subadviser. In addition, a fund’s investment strategies or policies may change from time to time. Those changes may not lead to the results intended by the subadviser and could have an adverse effect on the value or performance of a fund.

Illiquidity risk. Illiquidity risk exists when particular investments are impossible or difficult to sell. Although most of the funds’ investments must be liquid at the time of investment, investments may become illiquid after purchase by a fund, particularly during periods of market turmoil. Markets may become illiquid when, for instance, there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. As a general matter, dealers recently have been less willing to make markets for fixed income securities. When a fund holds illiquid investments, the portfolio may be harder to value, especially in changing markets, and if a fund is forced to sell these investments to meet redemption requests or for other cash needs, the fund may suffer a loss. A fund may experience heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of your investment to decline. In addition, when there is illiquidity in the market for certain investments, a fund, due to limitations on illiquid investments, may be unable to achieve its desired level of exposure to a certain sector. If Premier Institutional Liquid Reserves’ weekly liquid assets fall below certain designated thresholds, Premier Institutional Liquid Reserves may impose a fee of up to 2% on redemptions from the fund or temporarily restrict redemptions from the fund for up to 10 business days in any given 90-day period.

Valuation risk. The sales price a fund could receive for any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. Investors who purchase or redeem fund shares on days when a fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. A fund’s ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of a fund’s investments involves subjective judgment.

Redemption risk (Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves). A fund may experience periods of heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets. Redemption risk is greater to the extent that a fund has investors with large shareholdings, short

investment horizons, or unpredictable cash flow needs. In addition, redemption risk is heightened during periods of overall market turmoil. The redemption by one or more large shareholders of their holdings in a fund could hurt performance and/or cause the remaining shareholders in the fund to lose money. A fund’s redemption risk is increased if one decision maker has control of fund shares owned by separate fund shareholders, including clients or affiliates of the fund’s manager. If a fund is forced to liquidate its assets under unfavorable conditions or at inopportune times, the fund’s ability to maintain a stable $1.00 share price may be affected. In addition, a fund may suspend redemptions when permitted by applicable regulations.

Redemption risk (Premier Institutional Liquid Reserves). The fund may experience periods of heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets. Redemption risk is greater to the extent that the fund has investors with large shareholdings, short investment horizons, or unpredictable cash flow needs. In addition, redemption risk is heightened during periods of overall market turmoil. The redemption by one or more large shareholders of their holdings in the fund could hurt performance and/or cause the remaining shareholders in the fund to lose money. The fund’s redemption risk is increased if one decision maker has control of fund shares owned by separate fund shareholders, including clients or affiliates of the fund’s manager. If the fund is forced to liquidate its assets under unfavorable conditions or at inopportune times, the fund’s share price could decline. In addition, the fund may impose a fee or suspend redemptions under certain conditions.

Risk relating to investments by other funds. Other funds, including affiliated funds, may invest in a fund. From time to time, a fund may experience relatively large redemptions or investments from these funds as a result of their rebalancing their portfolios or for other reasons. In the event of such redemptions or investments, a fund could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

Repurchase agreements risk (Premier Institutional Government Reserves and Premier Institutional Liquid Reserves). Repurchase agreements could involve certain risks in the event of default or insolvency of the seller, including losses and possible delays or restrictions upon a fund’s ability to dispose of the underlying securities. To the extent that, in the meantime, the value of the securities that a fund has purchased has decreased, a fund could experience a loss. Premier Institutional Liquid Reserves may enter into repurchase agreements that are secured by collateral other than cash and government securities, including high yield and other types of securities with credit quality below what the fund could hold directly without the repurchase obligation. Such collateral may be more volatile or less liquid than government securities, thereby increasing the risk that the fund will be unable to recover fully in the event of a counterparty’s default. High yield securities (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties and potential illiquidity.

Operational risk. Your ability to transact with a fund or the valuation of your investment may be negatively impacted because of the operational risks arising from factors such as processing errors and human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third party service providers or trading counterparties. It is not possible to identify all of the operational risks that may affect a fund or to develop processes and controls that completely eliminate or mitigate the occurrence of such failures. A fund and its shareholders could be negatively impacted as a result.

Cybersecurity risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information), or proprietary information, cause a fund, the manager, the subadviser and/or their service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions. A fund, the manager, and the subadviser have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund or the manager. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent any future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

$1.00 Net Asset Value (Premier Institutional U.S. Treasury Reserves). If the market value of one or more of the fund’s investments changes substantially and the fund’s net asset value per share is at risk of falling below $1.00, the fund could, if authorized by the Board, maintain a $1.00 per share net asset value by reducing proportionately the number of shares owned by each shareholder. This would have the same economic effect as the fund’s shares being valued at less than $1.00 per share, which means that you will have lost money. By investing in the fund, you agree to this reduction should it become necessary.

Please note that there are other factors that could adversely affect your investment and that could prevent a fund from achieving its investment objective. More information about risks appears in the SAI. Before investing, you should carefully consider the risks that you will assume.

A description of the funds’ policies and procedures with respect to the disclosure of portfolio securities is available in the SAI. Each fund intends to make complete portfolio holdings information as of the last business day of each month available at www.leggmason.com/moneymarketfunds (click on the name of the fund) no later than five business days after month-end. Monthly portfolio holdings information will be available on each fund’s website for at least six months after posting.

Legg Mason Partners Fund Advisor, LLC (“LMPFA” or the “manager”) is each fund’s investment manager. LMPFA, with offices at 620 Eighth Avenue, New York, New York 10018, also serves as the investment manager of other Legg Mason-sponsored funds. LMPFA provides administrative and certain oversight services to the funds. As of June 30, 2019, LMPFA’s total assets under management were approximately $192.8 billion.

Western Asset Management Company, LLC (“Western Asset”) provides the day-to-day portfolio management of each fund as subadviser. Western Asset, established in 1971, has offices at 385 East Colorado Boulevard, Pasadena, California 91101 and 620 Eighth Avenue, New York, New York 10018. Western Asset acts as investment adviser to institutional accounts, such as corporate pension plans, mutual funds and endowment funds. As of June 30, 2019, the total assets under management of Western Asset and its supervised affiliates were approximately $445.5 billion.

LMPFA pays the subadviser a portion of the management fee that it receives from each fund. The funds do not pay any additional advisory or other fees for advisory services provided by Western Asset.

LMPFA and Western Asset are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”). Legg Mason, whose principal executive offices are at 100 International Drive, Baltimore, Maryland 21202, is a global asset management company. As of June 30, 2019, Legg Mason’s asset management operations, including Western Asset and its supervised affiliates, had aggregate assets under management of approximately $780.2 billion.

Each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves, pays a management fee at an annual rate that decreases as assets increase, as follows: 0.250% on assets up to and including $1 billion; 0.225% on assets over $1 billion, up to and including $2 billion; 0.200% on assets over $2 billion, up to and including $5 billion; 0.175% on assets over $5 billion, up to and including $10 billion; and 0.150% on assets over $10 billion.

Premier Institutional Liquid Reserves, pays a management fee at an annual rate that decreases as assets increase, as follows: 0.200% on assets up to and including $5 billion; 0.175% on assets over $5 billion, up to and including $10 billion; and 0.150% on assets over $10 billion.

A discussion regarding the basis for the Board’s approval of each fund’s management agreement and subadvisory agreement will be available in each fund’s first shareholder report.

The manager has agreed to waive fees and/or reimburse operating expenses (other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses) so that total annual operating expenses for Capital Shares and Premium Shares will not exceed the following percentages of the class’ average daily net assets, subject to recapture as described below:

These arrangements are expected to continue until December 31, 2020, may be terminated prior to that date by agreement of the manager and the Board, and may be terminated at any time after that date by the manager. Additional amounts may be voluntarily waived and/or reimbursed from time to time. The manager is also permitted to recapture amounts waived and/or reimbursed to a class during the same fiscal year if the class’ total annual operating expenses have fallen to a level below the limit described above. In no case will the manager recapture any amount that would result, on any particular business day of a fund, in the class’ total annual operating expenses exceeding the applicable limit described above, or any other lower limit then in effect.

Each fund enters into contractual arrangements with various parties, including, among others, each fund’s investment manager and the subadviser, who provide services to the funds. Shareholders are not parties to, or intended (or “third-party”) beneficiaries of, those contractual arrangements.

This Prospectus and the SAI provide information concerning each fund that you should consider in determining whether to purchase shares of a fund. A fund may make changes to this information from time to time. Neither this Prospectus nor the SAI is intended to give rise to any contract rights or other rights in any shareholder, other than rights conferred by federal or state securities laws.

Each fund is authorized to pay fees for recordkeeping services to Service Agents. As a result, operating expenses of classes that incur new or additional recordkeeping fees may increase over time.

Legg Mason Investor Services, LLC (“LMIS”), a wholly-owned broker/dealer subsidiary of Legg Mason, serves as each fund’s sole and exclusive distributor.

The distributor, the manager and/or their affiliates make payments for distribution, shareholder servicing, marketing and promotional activities and related expenses out of their profits and other available sources, including profits from their relationships with each fund. These payments are not reflected as additional expenses in the fee tables contained in this Prospectus. The recipients of these payments may include each fund’s distributor and affiliates of the manager, as well as Service Agents through which investors may purchase shares of each fund, including your Service Agent. The total amount of these payments is substantial, may be substantial to any given recipient and may exceed the costs and expenses incurred by the recipient for any fund-related marketing or shareholder servicing activities. The payments described in this paragraph are often referred to as “revenue sharing payments.” Revenue sharing arrangements are separately negotiated between the distributor, the manager and/or their affiliates, and the recipients of these payments.

Revenue sharing payments create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of each fund to you. Contact your Service Agent for details about revenue sharing payments it receives or may receive. Additional information about revenue sharing payments is available in the SAI. Revenue sharing payments, as well as payments by each fund under the shareholder services and distribution plan (where applicable), or for recordkeeping and/or shareholder services, also benefit the manager, the distributor and their affiliates to the extent the payments result in more assets being invested in the fund on which fees are being charged.

Shares of the funds are offered continuously and purchases may be made on any day the funds are open for business, as described under “Share price/Fund business days” below.

Your Service Agent may provide shareholder services that differ from the services provided by other Service Agents. Services provided by your Service Agent may vary by class. You should ask your Service Agent to explain the shareholder services it provides for each class and the compensation it receives in connection with each class. Remember that your Service Agent may receive different compensation depending on the share class in which you invest.

Your Service Agent may not offer all classes of shares. You should contact your Service Agent for further information.

Your account statement will have more information on who to contact if you want to buy, exchange or redeem shares, or you can contact your fund between 8:00 a.m. and 5:30 p.m. (Eastern time) at 1-877-721-1926 or 1-203-703-6002.

Exchanging shares (Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves only)

When you buy, exchange or redeem shares, your request must be in good order. This means you have provided the following information, without which your request may not be processed:

In certain circumstances, such as during periods of market volatility, severe weather and emergencies, shareholders may experience difficulties placing exchange or redemption orders by telephone. In that case, shareholders should consider using a fund’s other exchange and redemption procedures described under “Exchanging shares” and “Redeeming shares.”

The transfer agent or the funds will employ reasonable procedures to confirm that any telephone, electronic or other exchange or redemption request is genuine, which may include recording calls, asking the caller to provide certain personal identification information, employing identification numbers, sending you a written confirmation or requiring other confirmation procedures from time to time. If these procedures are followed, neither a fund nor its agents will bear any liability for these transactions, subject to applicable law.

Each fund does not consider the U.S. Postal Service or private delivery services to be its agents. Therefore, deposits in the mail or with such delivery services, or receipt at a fund’s post office box, of purchase requests or redemption orders, do not constitute receipt by a fund or its transfer agent.

For your protection, the funds or your Service Agent may request additional information in connection with large redemptions, unusual activity in your account, or otherwise to ensure your redemption request is in good order. Please contact your Service Agent or the funds for more information.

To be in good order, your redemption request must include a Medallion signature guarantee if you:

When a Medallion signature guarantee is called for, the shareholder should have a Medallion signature guarantee stamped under his or her signature. You can obtain a signature guarantee from most banks, dealers, brokers, credit unions and federal savings and loan institutions, national securities exchanges, registered securities associations and clearing agencies (each an “Eligible Guarantor Institution”), but not from a notary public.

Each fund and its agents reserve the right to reject any Medallion signature guarantee pursuant to written signature guarantee standards or procedures, which may be revised in the future to permit them to reject Medallion signature guarantees from Eligible Guarantor Institutions. A fund may change the signature guarantee requirements from time to time without prior notice to shareholders.

The distribution of this Prospectus and the offering of shares of the funds are restricted in certain jurisdictions. This Prospectus is not an offer or solicitation in any jurisdiction where such offer or solicitation is unlawful, where the person making an offer or solicitation is not authorized to make

it or a person receiving an offer or solicitation may not lawfully receive it or may not lawfully invest in the funds. Investors should inform themselves as to the legal requirements within their own country before investing in the funds.

This Prospectus, and the offer of shares hereunder, are not directed at persons outside the United States. In particular, a fund is not intended to be marketed to prospective investors in any member state of the European Union, Iceland, Liechtenstein or Norway (collectively, the “European Economic Area” or “EEA”). No notification or application has been made to the competent authority of any member state of the EEA under the Alternative Investment Fund Managers Directive (or any applicable legislation or regulations made thereunder) to market a fund to investors in the EEA and it is not intended that any such notification or application shall be made.

U.S. citizens with addresses in the United States, and non-U.S. citizens who reside in the United States and have U.S. addresses, are permitted to establish accounts with a fund. For these purposes, the “United States” and “U.S.” include U.S. territories.

A fund generally does not permit persons who do not reside in the United States or who do not have U.S. addresses to establish accounts. Therefore, U.S. citizens residing in foreign countries, as well as non-U.S. citizens residing in foreign countries, generally will not be permitted to establish accounts with a fund.

For further information, you or your Service Agent may contact the funds at 1-877-721-1926 or 1-203-703-6002.

Federal anti-money laundering regulations require all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you sign your account application, you may be asked to provide additional information in order for a fund to verify your identity in accordance with these regulations. If you are opening the account in the name of a legal entity (e.g. partnership, limited liability company, business trust, corporation, etc.), you may also be required to supply the identity of the beneficial owners and a control individual with management authority, prior to the opening of your account. Accounts may be restricted and/or closed, and the monies withheld, pending verification of this information or as otherwise required under these and other federal regulations.

Each fund reserves the right to ask you to bring your account up to a minimum investment amount determined by your Service Agent if the aggregate value of the fund shares in your account is less than $500 for any reason (including solely due to declines in net asset value and/or failure to invest at least $500 within a reasonable period). You will be notified in writing and will have 60 days to make an additional investment to bring your account value up to the required level. If you choose not to do so within this 60-day period, the fund may close your account and send you the redemption proceeds. If your share class is no longer offered, you may not be able to bring your account up to the minimum investment amount. Some shareholders who hold accounts in multiple classes of the same fund may have those accounts aggregated for the purposes of these calculations. If your account is closed, you will not be eligible to have your account reinstated without imposition of any sales charges that may apply to your new purchase.

Please contact your Service Agent for more information. Any redemption of fund shares may result in tax consequences to you (see “Taxes” for more information). Each fund may, with prior notice, change the minimum size of accounts subject to mandatory redemption, which may vary by class, or implement fees for small accounts.

Subject to applicable law, a fund may, with prior notice, adopt other policies from time to time requiring mandatory redemption of shares in certain circumstances.

For more information, please contact your Service Agent or the funds or consult the SAI.

Money market funds are often used by investors for short-term investments, in place of bank checking or saving accounts, or for cash management purposes. Investors value the ability to add and withdraw their funds quickly, without restriction. For this reason the funds’ Board has not adopted policies and procedures, or imposed restrictions such as minimum holding periods, in order to deter frequent purchases and redemptions of money market fund shares. The Board also believes that money market funds, such as the funds, are not typically targets of abusive trading practices. However, some investors may seek to take advantage of a short-term disparity between a fund’s yield and current market yields, which could have the effect of reducing the fund’s yield. In addition, frequent purchases and redemptions of fund shares could increase a fund’s portfolio transaction costs and may interfere with the efficient management of the fund’s portfolio, which could detract from the fund’s performance.

Reduction in number of shares-Premier Institutional U.S. Treasury Reserves only

In order to maintain a $1.00 per share net asset value, if the value of a fund’s assets were to decline, the fund could, if authorized by the Board, reduce the number of its outstanding shares through a reverse stock split. If this happens, although each share would continue to be valued at $1.00 per share, each shareholder will own fewer shares of the fund and lose money. A fund could do this if, for example, there were a default on an investment held by the fund, if expenses exceed the fund’s income, or if an investment declined significantly in value. By investing in a fund, you agree to this reduction should it become necessary to maintain a $1.00 per share net asset value.

If you hold shares through a Service Agent, your Service Agent may establish and maintain your account and be the shareholder of record. In the event that a fund holds a shareholder meeting, your Service Agent, as record holder, will be entitled to vote your shares and may seek voting instructions from you. If you do not give your Service Agent voting instructions, your Service Agent, under certain circumstances, may nonetheless be entitled to vote your shares.

Each fund calculates its net income and declares dividends each business day when it makes its final net asset value calculation. See “Buying shares” above for information about when recently purchased shares begin to earn dividends and “Redeeming shares” above for information about when shares redeemed cease to earn dividends. Dividends are distributed once a month, on or before the last business day of the month.

Unless you elect to receive dividends and/or other distributions in cash, your dividends and capital gain distributions will be automatically reinvested in shares of the same class you hold, at the net asset value determined on the reinvestment date.

If you hold shares directly with a fund and you elect to receive dividends and/or distributions in cash, you have the option to receive such dividends and/or distributions via a direct deposit to your bank account or, provided that the dividend and/or distribution is $10.00 or more, by check. If you choose to receive dividends and/or distributions via check, amounts less than $10.00 will automatically be reinvested in fund shares as described above.

If you do not want dividends and/or distributions in amounts less than $10.00 to be reinvested in fund shares, you must elect to receive dividends and distributions via a direct deposit to your bank account.

The Board reserves the right to revise the dividend policy or postpone the payment of dividends if warranted in the Board’s judgment due to unusual circumstances.

The following discussion is very general, applies only to shareholders who are U.S. persons, and does not address shareholders subject to special rules, such as those who hold fund shares through an IRA, 401(k) plan or other tax-advantaged account. Except as specifically noted, the discussion is limited to federal income tax matters, and does not address state, local, foreign or non-income taxes. Further information regarding taxes, including certain federal income tax considerations relevant to non-U.S. persons, is included in the SAI. Because each shareholder’s circumstances are different and special tax rules may apply, you should consult your tax adviser about federal, state, local and/or foreign tax considerations that may be relevant to your particular situation.

You normally will have to pay federal income tax on any dividends and other distributions you receive from a fund, whether the distributions are paid in cash or additional shares. Distributions of net capital gain (the excess of net long-term capital gain over net short-term capital loss) that are reported by a fund as capital gain dividends are taxable to you as long-term capital gain regardless of how long you have owned your shares. Other distributions are generally taxable as ordinary income. The funds do not expect any distributions to be treated as qualified dividend income, which for noncorporate shareholders may be taxed at reduced rates.

If you redeem shares or exchange them for shares of another fund, it is generally a taxable event. However, for each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves you will not have any gain or loss on the redemption or exchange so long as the fund whose shares you redeem or exchange maintains a net asset value of $1.00 per share.

For Premier Institutional Liquid Reserves only. You may elect the “NAV method” for computing gains and losses from redemptions. Under the NAV method, rather than computing gain or loss separately for each taxable disposition of fund shares, you would determine gain or loss on an aggregate basis for each “computation period” (which could be a taxable year or certain shorter periods within a taxable year). Gain or loss under the NAV method would be based on the change in the aggregate value of your shares during the applicable period (or, for the first period in which the NAV method applies, the difference between the aggregate value at the end of the period and the adjusted tax basis at the beginning of the period), reduced by your purchases of fund shares (including purchases through reinvestment of dividends) and increased by the proceeds of redemptions of fund shares during that period. Under the NAV method, if you hold your shares as a capital asset, any resulting net gain or loss would be treated as short-term capital gain or loss. If you hold shares in the fund through more than one account, you must treat your holdings in each such account as a separate fund for purposes of applying the NAV method. If you do not elect the NAV method, any capital gain or loss will generally be long-term capital gain or loss if you held your shares for more than one year and short-term capital gain or loss if you held the shares for one year or less. Any such loss will be disallowed to the extent your fund shares are replaced, including replacement through the reinvesting of dividends and capital gains distributions in the fund, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares you acquired will be increased to reflect the disallowed loss.

There is uncertainty with respect to the tax treatment of liquidity fees received by Premier Institutional Liquid Reserves. The tax treatment of liquidity fees may be the subject of future guidance issued by the Internal Revenue Service. The imposition of a liquidity fee on your redemption of fund shares could cause you to recognize a loss or could decrease the gain or increase the loss you would otherwise recognize. Although there is no definitive guidance, any liquidity fees received by Premier Institutional Liquid Reserves may result in distributions or gains that would be taxable to the fund’s shareholders.

If the fund meets certain requirements with respect to its holdings, it may elect to “pass through” to shareholders foreign taxes that it pays, in which case each shareholder will include the amount of such taxes in computing gross income, but will be eligible to claim a credit or deduction for such taxes, subject to generally applicable limitations on such deductions and credits.

For all funds. A Medicare contribution tax is imposed at the rate of 3.8% on all or a portion of net investment income of U.S. individuals if their income exceeds specified thresholds and on all or a portion of undistributed net investment income of certain estates and trusts. Net investment income generally includes for this purpose dividends and capital gain distributions, if any, paid by a fund.

A dividend declared by a fund in October, November or December and paid during January of the following year will, in certain circumstances, be treated as paid in December for tax purposes.

After the end of each year, your Service Agent or fund will provide you with information about the distributions and dividends you received and, for Premier Institutional Liquid Reserves, any redemptions of shares during the previous year. Because each shareholder’s circumstances are different and special tax rules may apply, you should consult your tax adviser about your investment in a fund.

You may buy or redeem shares at their net asset value (“NAV”) next determined after receipt of your request in good order. You may exchange shares at the final NAV calculated on a fund business day after receipt of your request in good order.

Each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves uses the amortized cost method to value its portfolio securities. Using this method, each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves constantly amortizes over the remaining life of a security the difference between the principal amount due at maturity and the cost of the security to the fund. This method of valuation is designed to permit a money market fund to maintain a constant NAV of $1.00 per share, but there is no guarantee that it will do so.

Valuation of Premier Institutional Liquid Reserves’ securities and other assets is performed in accordance with procedures approved by the Board. These procedures delegate most valuation functions to the manager, which generally uses independent third party pricing services approved by the Board. Under the procedures, assets are valued as follows:

Many factors may influence the price at which Premier Institutional Liquid Reserves could sell any particular portfolio investment. The sales price may well differ—higher or lower—from Premier Institutional Liquid Reserves’ last valuation, and such differences could be significant, particularly for securities that trade in relatively thin markets and/or markets that experience extreme volatility. Moreover, valuing securities using fair value methodologies involves greater reliance on judgment than valuing securities based on market quotations. A fund that uses fair value methodologies may value those securities higher or lower than another fund using market quotations or its own fair value methodologies to price the same securities. There can be no assurance that Premier Institutional Liquid Reserves could obtain the value assigned to a security if it were to sell the security at approximately the time at which Premier Institutional Liquid Reserves determines its net asset value. Investors who purchase or redeem fund shares on days when Premier Institutional Liquid Reserves is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if Premier Institutional Liquid Reserves had not fair-valued the security or had used a different methodology.

Each fund’s NAV per share is the value of its assets minus its liabilities divided by the number of shares outstanding. NAV is calculated separately for each class of shares. Each fund is open for business and calculates its NAV every day on which both the NYSE and the Federal Reserve Bank of New York (“FRBNY”) are open for business. Therefore, the funds will be closed on the days on which the following holidays are observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving Day and Christmas Day. Both the NYSE and FRBNY are also closed on weekends and may be closed because of an emergency or other unanticipated event. In the event the Federal Reserve wire payment system is open and the NYSE is open, a fund may close for purchase or redemption transactions if—due to an emergency or other unanticipated event—the bond markets are closed for business as recommended by the Securities Industry and Financial Markets Association (“SIFMA”). In the event the NYSE does not open for business because of an emergency or other unanticipated event, a fund may, but is not required to, open for purchase or redemption transactions if the Federal Reserve wire payment system is open and the bond markets are open.

Premier Institutional Liquid Reserves typically values its securities and calculates its NAV as of 8:00 a.m., 12:00 p.m., and 3:00 p.m. (Eastern time) on each fund business day. Each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves typically calculates its NAV as of each hour from 9:00 a.m. (Eastern time) until its close of business on each fund business day. However, a fund could, without advance notice, determine not to make one or more intraday calculations on a given day for a number of reasons such as unusual conditions in the bond, credit or other markets or unusual fund purchase or redemption activity. If a fund determined not to make an intraday calculation, purchases or redemptions would be effected at the next determined intraday or closing NAV, which may be greater or less than the price at which the purchase or redemption would otherwise have been effected.

On any day when the NYSE, the FRBNY or the bond markets (as recommended by SIFMA) close early due to an unanticipated event, or if trading on the NYSE is restricted, an emergency arises or as otherwise permitted by the SEC, each fund reserves the right to close early and make its final NAV calculation as of the time of its early close.

Each fund normally closes for business at the following times: Premier Institutional Government Reserves at 5:00 p.m. (Eastern time), Premier Institutional Liquid Reserves at 3:00 p.m. (Eastern time), and Premier Institutional U.S. Treasury Reserves at 2:00 p.m. (Eastern time). When SIFMA recommends an early close to the bond markets on a business day before or after a day on which a holiday is celebrated, each fund reserves the right to close at or prior to the SIFMA recommended closing time. For calendar year 2019, SIFMA recommends an early close of the bond markets on November 29, 2019; December 24, 2019 and December 31, 2019. For calendar year 2020, SIFMA recommends an early close of the bond markets on April 9, 2020; May 22, 2020; July 2, 2020; November 27, 2020; December 24, 2020 and December 31, 2020. The schedule may be changed by SIFMA due to market conditions.

To determine whether a fund is open for business, please call the fund at 1-877-721-1926 or 1-203-703-6002. The fund service desk is generally open between 8:00 a.m. and 5:30 p.m. (Eastern time) but may close early under certain circumstances. You should contact your Service Agent to determine whether your Service Agent will be open for business.

It is the responsibility of the Service Agent to transmit all orders to buy, exchange or redeem shares to the transfer agent on a timely basis.

As the funds have not commenced operations as of the date of this Prospectus, no financial information is available. The Prospectus will include financial information for each fund once it has issued its first annual report to shareholders that contains audited financial statements.

The Board believes that the aggregate per share expenses of the Fund and its corresponding Portfolio will be less than or approximately equal to the expenses that the Fund would incur if the assets of the Fund were invested directly in the types of securities held by its Portfolio. The Fund may withdraw its investment in its Portfolio at any time, and will do so if the Fund’s Trustees believe it to be in the best interest of the Fund’s shareholders. If the Fund were to withdraw its investment in its Portfolio, the Fund could either invest directly in securities in accordance with its investment policies or invest in one or more other mutual funds or pooled investment vehicles having similar investment objectives and policies. If the Fund were to withdraw, the Fund could receive securities from its Portfolio instead of cash, causing the Fund to incur brokerage, tax and other charges or leaving it with securities that may or may not be readily marketable or widely diversified.

The Portfolio may change its investment objective, investment strategies and certain of its investment policies and restrictions without approval by its investors, but it will notify its corresponding Fund and its other investors before implementing any change in its investment objective. A change in the Portfolio’s investment objective, investment strategies, policies or restrictions may cause the Fund to withdraw its investment in its Portfolio.

The Portfolio is a series of a Maryland statutory trust, is not required to hold and have no intention of holding annual meetings of investors. However, when the Portfolio is required to do so by law or in the judgment of its Trustees it is necessary or desirable to do so, the Portfolio will submit matters to its investors for a vote. When the Fund is asked to vote on matters concerning its corresponding Portfolio (other than a vote to continue the Portfolio following the withdrawal of an investor), the Fund will either hold a shareholder meeting and vote in accordance with shareholder instructions, or otherwise act in accordance with applicable law. Of course, the Fund could be outvoted, or otherwise adversely affected, by other investors in the Portfolio.

The Portfolio may sell interests to investors in addition to its corresponding Fund. These investors may be funds which offer shares to their shareholders with different costs and expenses than the Fund. Therefore, the investment returns for all investors in funds investing in a portfolio may not be the same. These differences in returns are also present in other mutual fund structures.

The Portfolio is open for business on each day that its corresponding Fund is open for business as set forth in the Fund’s Prospectus. The Portfolio determines its NAV at the same time or times on each fund business day as its corresponding Fund. The Portfolio may make additional NAV calculations to accommodate the NAV calculation times of other investors, such as other funds, that invest in the Portfolio. The Fund may add to or reduce its investment in its Portfolio on each fund business day. For more information, see the Fund’s Prospectus.

Information about other holders of interests in the Portfolio is available from LMIS.

Each Fund may, in the future, convert to a fund of funds structure. In a fund of funds structure, a fund invests all or a portion of its assets in multiple investment companies.

References to the “Fund” in this SAI as it applies to each of Premier Institutional Government Reserves, Premier Institutional Liquid Reserves and Premier Institutional U.S. Treasury Reserves include the Portfolio in which they invest, unless the context requires otherwise.

The Fund and the Portfolio (as applicable) is registered under the 1940 Act as an open-end management investment company. The Fund’s Prospectus discusses the Fund’s investment objective and strategies. The following is a summary of certain strategies and investment limitations of the Fund and supplements the description of the Fund’s investment strategies in its Prospectus. Additional information regarding investment practices and risk factors with respect to the Fund may also be found below in the section entitled Investment Practices and Risk Factors.

The Fund and the Portfolio (as applicable) have adopted the fundamental and non-fundamental investment policies below for the protection of shareholders. References to the Fund in this section include the Portfolio, unless the context requires otherwise. Fundamental investment policies of the Fund may not be changed without a 1940 Act Vote. The Board may change non-fundamental investment policies at any time.

Whenever the Fund is requested to vote on a change in the fundamental investment policies of the Portfolio, the Fund will either call a meeting of its shareholders and will vote its shares in the Portfolio in accordance with instructions it receives from its shareholders, or vote its shares in the Portfolio in the same proportion as the vote of all other investors in the Portfolio.

If any percentage restriction described below (other than the limitation on borrowing) is complied with at the time of an investment, a later increase or decrease in the percentage resulting from a change in asset values or characteristics will not constitute a violation of such restriction, unless otherwise noted below.

Borrowing. The Fund may not borrow money except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

Underwriting. The Fund may not engage in the business of underwriting the securities of other issuers except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

Lending. The Fund may lend money or other assets to the extent permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

Senior Securities. The Fund may not issue senior securities except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

Real Estate. The Fund may not purchase or sell real estate except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

Commodities. The Fund may purchase or sell commodities or contracts related to commodities to the extent permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

Premier Institutional Government Reserves. Except as permitted by exemptive or other relief or permission from the SEC, SEC staff or other authority with appropriate jurisdiction, the Fund may not make any investment if, as a result, the Fund’s investments will be concentrated in any one industry, except that the Fund may invest without limit in obligations issued by banks.

Premier Institutional U.S. Treasury Reserves. The Fund may not purchase any securities of an issuer in a particular industry if as a result 25% or more of its total assets (taken at market value at the time of purchase) would be invested in securities of issuers whose principal business activities are in the same industry.

Premier Institutional Liquid Reserves. The Fund may not purchase any securities of an issuer in a particular industry if as a result 25% or more of its total assets (taken at market value at the time of purchase) would be invested in securities of issuers whose principal business activities are in the same industry, except that the Fund may invest at least 25% of its assets in bank obligations issued by domestic banks.

For purposes of the investment restrictions described above, the issuer of a tax-exempt security is deemed to be the entity (public or private) principally responsible for the payment of principal of and interest on the security. If, however, the creating government or some other entity, such as an insurance company or other corporate obligor, guarantees a security or a bank issues a letter of credit, such a guarantee or letter of credit may, in accordance with applicable SEC rules, be considered a separate security and treated as an issue of such government, other entity or bank.

With respect to the fundamental policy relating to borrowing money set forth above, the 1940 Act permits a fund to borrow money in amounts of up to one-third of the fund’s total assets from banks for any purpose, and to borrow up to 5% of the fund’s total assets from banks or other lenders for temporary purposes. (A fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the 1940 Act requires a fund to maintain an “asset coverage” of at least 300% of the amount of its borrowings, provided that in the event that the fund’s asset coverage falls below 300%, the fund is required to reduce the amount of its borrowings so that it meets the 300% asset coverage threshold within three days (not including Sundays and holidays). Asset coverage means the ratio that the value of a fund’s total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowing, and thus, subject to the 1940 Act

restrictions. Borrowing money to increase portfolio holdings is known as “leveraging.” Borrowing, especially when used for leverage, may cause the value of the Fund’s shares to be more volatile than if the Fund did not borrow. This is because borrowing tends to magnify the effect of any increase or decrease in the value of the Fund’s portfolio holdings. Borrowed money thus creates an opportunity for greater gains, but also greater losses. To repay borrowings, the Fund may have to sell securities at a time and at a price that is unfavorable to the Fund. There also are costs associated with borrowing money, and these costs would offset and could eliminate the Fund’s net investment income in any given period. Currently, no Fund contemplates borrowing money for leverage, but if it does so, it will not likely do so to a substantial degree. The policy above will be interpreted to permit the Fund to engage in trading practices and investments that may be considered to be borrowing to the extent permitted by the 1940 Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth above, the 1940 Act does not prohibit a fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, the 1940 Act permits a fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of the fund’s underwriting commitments, when added to the value of the fund’s investments in issuers where the fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Under the 1933 Act, an underwriter may be liable for material omissions or misstatements in an issuer’s registration statement or prospectus. Securities purchased from an issuer and not registered for sale under the 1933 Act are considered restricted securities. There may be a limited market for these securities. If these securities are registered under the 1933 Act, they may then be eligible for sale but participating in the sale may subject the seller to underwriter liability. These risks could apply to a fund investing in restricted securities. Although it is not believed that the application of the 1933 Act provisions described above would cause the Fund to be engaged in the business of underwriting, the policy above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act.

With respect to the fundamental policy relating to lending set forth above, the 1940 Act does not prohibit a fund from making loans; however, SEC staff interpretations currently prohibit funds from lending more than one-third of their total assets, except through the purchase of debt obligations or the use of repurchase agreements. (A repurchase agreement is an agreement to purchase a security, coupled with an agreement to sell that security back to the original seller on an agreed-upon date at a price that reflects current interest rates. The SEC frequently treats repurchase agreements as loans.) While lending securities may be a source of income to the Fund, as with other extensions of credit, there are risks of delay in recovery or even loss of rights in the underlying securities should the borrower fail financially. However, loans would be made only when the Fund’s Manager or Subadviser believes the income justifies the attendant risks. The Fund also will be permitted by this policy to make loans of money, including to other funds. The Fund would have to obtain exemptive relief from the SEC to make loans to other funds. The policy above will be interpreted not to prevent the Fund from purchasing or investing in debt obligations and loans.

With respect to the fundamental policy relating to issuing senior securities set forth above, “senior securities” are defined as fund obligations that have a priority over the fund’s shares with respect to the payment of dividends or the distribution of fund assets. The 1940 Act prohibits a fund from issuing senior securities, except that the fund may borrow money in amounts of up to one-third of the fund’s total assets from banks for any purpose. A fund also may borrow up to 5% of the fund’s total assets from banks or other lenders for temporary purposes, and these borrowings are not considered senior securities. The issuance of senior securities by a fund can increase the speculative character of the fund’s outstanding shares through leveraging. Leveraging of the Fund’s portfolio through the issuance of senior securities magnifies the potential for gain or loss on monies, because even though the Fund’s net assets remain the same, the total risk to investors is increased to the extent of the Fund’s gross assets.

With respect to the fundamental policy relating to real estate set forth above, the 1940 Act does not prohibit a fund from owning real estate; however, a fund is limited in the amount of illiquid assets it may purchase. Investing in real estate may involve risks, including that real estate is generally considered illiquid and may be difficult to value and sell. Owners of real estate may be subject to various liabilities, including environmental liabilities. To the extent that investments in real estate are considered illiquid, SEC rules limit a money market fund’s purchases of illiquid securities to 5% of total assets. The policy above will be interpreted not to prevent the Fund from investing in real estate-related companies, companies whose businesses consist

in whole or in part of investing in real estate, instruments (like mortgages) that are secured by real estate or interests therein, or real estate investment trust securities. As government money market funds, neither Premier Institutional Government Reserves nor Premier Institutional U.S. Treasury Reserves will invest in real estate.

With respect to the fundamental policy relating to commodities set forth above, the 1940 Act does not prohibit a fund from owning commodities, whether physical commodities and contracts related to physical commodities (such as oil or grains and related futures contracts), or financial commodities and contracts related to financial commodities (such as currencies and, possibly, currency futures). However, a fund is limited in the amount of illiquid assets it may purchase. To the extent that investments in commodities are considered illiquid, SEC rules limit a money market fund’s purchases of illiquid securities to 5% of total assets. If the Fund were to invest in a physical commodity or a physical commodity-related instrument, the Fund would be subject to the additional risks of the particular physical commodity and its related market. The value of commodities and commodity-related instruments may be extremely volatile and may be affected either directly or indirectly by a variety of factors. There also may be storage charges and risks of loss associated with physical commodities. The policy above will be interpreted to permit investments in exchange traded funds that invest in physical and/or financial commodities. As government money market funds, neither Premier Institutional Government Reserves nor Premier Institutional U.S. Treasury Reserves will invest in commodities.

With respect to the fundamental policy relating to concentration set forth above, the 1940 Act does not define what constitutes “concentration” in an industry. The SEC staff has taken the position that investment of 25% or more of a fund’s total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. A fund that invests a significant percentage of its total assets in a single industry may be particularly susceptible to adverse events affecting that industry and may be more risky than a fund that does not concentrate in an industry. The concentration policy above will be interpreted to refer to concentration as that term may be interpreted from time to time. In addition, the term industry will be interpreted to include related groups of industries. The SEC has taken the position that money market funds may reserve the right to invest without limit in instruments of domestic banks without being deemed to concentrate their investments. The policy above will be interpreted to permit investment without limit in domestic bank participation interests in municipal securities. Premier Institutional Government Reserves does not intend to purchase or concentrate in banking obligations. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized fully by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers based solely on their domicile in a single jurisdiction or country. The policy also will be interpreted to give broad authority to the Fund as to how to classify issuers within or among industries or groups of industries. The Fund has been advised by the staff of the SEC that the staff currently views securities issued by a foreign government to be in a single industry for purposes of calculating applicable limits on concentration. Neither Premier Institutional Government Reserves nor Premier Institutional U.S. Treasury Reserves invests in securities issued by foreign governments, and Premier Institutional Liquid Reserves does not intend to invest more than 25% of its assets in securities issued by a foreign government.

The Fund’s fundamental policies are written and will be interpreted broadly. For example, the policies will be interpreted to refer to the 1940 Act and the related rules as they are in effect from time to time, and to interpretations and modifications of or relating to the 1940 Act by the SEC and others as they are given from time to time. When a policy provides that an investment practice may be conducted as permitted by the 1940 Act, the policy will be interpreted to mean either that the 1940 Act expressly permits the practice or that the 1940 Act does not prohibit the practice.

Rule 2a-7 under the 1940 Act may limit a money market fund’s ability to engage in a strategy otherwise permitted under the 1940 Act.

Each of Premier Institutional Government Reserves, Premier Institutional Liquid Reserves and Premier Institutional U.S. Treasury Reserves is currently classified as a diversified fund under the 1940 Act. The Fund may only change to non-diversified status with a 1940 Act Vote.

Commodity Exchange Act Regulation- Exclusion from Commodity Pool Operator Definition

The Fund and the Portfolio are operated by persons who have claimed an exclusion, granted to operators of registered investment companies, like the Fund and the Portfolio, from registration as a “commodity pool operator” with respect to the Fund and the Portfolio under the CEA and, therefore are not subject to registration or regulation with respect to the Fund and the Portfolio under the CEA.

In addition to the investment strategies and the risks described in the Fund’s Prospectus and in this SAI under Investment Objective and Strategies, the Fund may employ other investment practices and may be subject to other risks, which are described below. The Fund may engage in the practices described below to the extent consistent with its investment objectives, strategies, policies and restrictions. However, as with any investment or investment technique, even when the Fund’s Prospectus or this discussion indicates that the Fund may engage in an activity, the Fund may not actually do so for a variety of reasons. In addition, new types of instruments and other securities may be developed and marketed from time to time. Consistent with its investment limitations, the Fund expects to invest in those new types of securities and instruments that its portfolio manager believes may assist the Fund in achieving its investment objective.

This discussion is not intended to limit the Fund’s investment flexibility, unless such a limitation is expressly stated, and therefore will be construed by the Fund as broadly as possible. Statements concerning what the Fund may do are not intended to limit any other activity.

The Fund may invest in U.S. dollar-denominated obligations of foreign banks, and in obligations of domestic banks, as that term has been interpreted by the SEC. Under SEC interpretations, a U.S. branch of a foreign bank may be considered a domestic bank if the U.S. branch of the foreign bank is subject to the same regulation as a U.S. bank. Likewise, a non-U.S. branch of a U.S. bank may be considered a domestic bank if the investment risk associated with investing in instruments issued by the non-U.S. branch is the same, in the opinion of the portfolio manager, as that of investing in instruments issued by the branch’s domestic parent. The Fund may also invest in Eurodollar and Yankee bank obligations.

Certificates of deposit (“CDs”) are savings certificates generally issued by commercial banks that bear a maturity date and a specified interest rate, and can be issued in any denomination. Fixed time deposits (“Fixed TDs”) are obligations which are payable at a stated maturity date and bear a fixed rate of interest. Generally, Fixed TDs may be withdrawn on demand by the Fund, but they may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation. Although Fixed TDs do not have a market, there are no contractual restrictions on the Fund’s right to transfer a beneficial interest in the deposit to a third party. A bankers’ acceptance is a draft drawn on and accepted by a bank that orders payment to a third party at a later date. Bankers’ acceptances generally act as a negotiable time draft for financing imports, exports, or other transactions in goods.

U.S. banks organized under federal law are supervised and examined by the Comptroller of the Currency and are required to be members of the Federal Reserve System and to be insured by the FDIC. U.S. banks organized under state law are supervised and examined by state banking authorities and are members of the Federal Reserve System only if they elect to join. However, state banks which are insured by the FDIC are subject to federal examination and to a substantial body of federal law and regulation. As a result of federal and state laws and regulations, U.S. branches of U.S. banks, among other things, are generally required to maintain specified levels of reserves, and are subject to other supervision and regulation designed to promote financial soundness.

The provisions of federal law governing the establishment and operation of U.S. branches do not apply to non-U.S. branches of U.S. banks. However, the Fund may purchase obligations only of those non-U.S. branches of U.S. banks which were established with the approval of the Board of Governors of the Federal Reserve System (the “Board of Governors”). As a result of such approval, these branches are subject to examination by the Board of Governors and the Comptroller of the Currency. In addition, such non-U.S. branches of U.S. banks are subject to the supervision of the U.S. bank and creditors of the non-U.S. branch are considered general creditors of the U.S. bank subject to whatever defenses may be available under the governing non-U.S. law and to the terms of the specific obligation. Nonetheless, the Fund generally will be subject to whatever risk may exist that the non-U.S. country may impose restrictions on payment of certificates of deposit or time deposits.

U.S. branches of non-U.S. banks are subject to the laws of the state in which the branch is located or to the laws of the United States. Such branches are therefore subject to many of the regulations, including reserve requirements, to which U.S. banks are subject.

Obligations of foreign branches of domestic banks and of foreign branches of foreign banks, such as CDs and Fixed TDs, may be general obligations of the parent bank in addition to the issuing branch, or may be limited by the terms of a specific obligation or by governmental regulation. Such obligations are subject to many of the same risks as those of domestic banks or domestic branches of foreign banks. They are also subject to risks such as future political and economic developments, the possible imposition of non-U.S. withholding taxes on interest income payable on such obligations held by the Fund, the possible seizure or nationalization of non-U.S. deposits and the possible establishment of exchange controls or other non-U.S. governmental laws or restrictions that might adversely affect payment of principal and interest on such obligations held by the Fund. Foreign branches of domestic banks and foreign branches of foreign banks are not necessarily subject to the same or similar regulatory requirements that apply to domestic banks, such as mandatory reserve requirements, loan limitations and accounting, auditing and financial record keeping requirements. Additionally, there may be less public information available about non-U.S. entities. Non-U.S. issuers may be subject to less governmental regulation and supervision than U.S. issuers. Non-U.S. issuers also generally are not bound by uniform accounting, auditing and financial reporting requirements comparable to those applicable to U.S. issuers.

The Fund may engage in borrowing transactions as a means of raising cash to satisfy redemption requests, for other temporary or emergency purposes or, to the extent permitted by its investment policies, to raise additional cash to be invested by the Fund in other securities or instruments in an effort to increase the Fund’s investment returns. Reverse repurchase agreements may be considered to be a type of borrowing.

When the Fund invests borrowing proceeds in other securities, the Fund will be at risk for any fluctuations in the market value of the securities in which the proceeds are invested. Like other leveraging risks, this makes the value of an investment in the Fund more volatile and increases the Fund’s overall investment exposure. In addition, if the Fund’s return on its investment of the borrowing proceeds does not equal or exceed the interest that the Fund is obligated to pay under the terms of a borrowing, engaging in these transactions will lower the Fund’s return.

The Fund may be required to liquidate portfolio securities at a time when it would be disadvantageous to do so in order to make payments with respect to its borrowing obligations. Interest on any borrowings will be an expense to the Fund and will reduce the value of the Fund’s shares. The Fund may borrow on a secured or on an unsecured basis. If the Fund enters into a secured borrowing arrangement, a portion of the Fund’s assets will be used as collateral. During the term of the borrowing, the Fund will remain at risk for any fluctuations in the market value of these assets in addition to any securities purchased with the proceeds of the loan. In addition, the Fund may be unable to sell the collateral at a time when it would be advantageous to do so, which could result in lower returns. The Fund would also be subject to the risk that the lender may file for bankruptcy, become insolvent, or otherwise default on its obligations to return the collateral to the Fund. In the event of a default by the lender, there may be delays, costs and risks of loss involved in the Fund’s exercising its rights with respect to the collateral or those rights may be limited by other contractual agreements or obligations or by applicable law.

The 1940 Act requires to maintain an “asset coverage” of at least 300% of the amount of its borrowings, provided that in the event that the Fund’s asset coverage falls below 300%, the Fund is required to reduce the amount of its borrowings so that it meets the 300% asset coverage threshold within three days (not including Sundays and holidays). Asset coverage means the ratio that the value of the Fund’s total assets, minus liabilities other than borrowings and other senior securities, bears to the aggregate amount of all borrowings. Although complying with this guideline would have the effect of limiting the amount that the Fund may borrow, it does not otherwise mitigate the risks of entering into borrowing transactions.

Commercial paper (including variable amount master demand notes and funding agreements) consists of short-term, unsecured promissory notes issued by corporations, partnerships, trusts and other entities to finance short-term credit needs.

The Fund may acquire custodial receipts or certificates underwritten by securities dealers or banks that evidence ownership of future interest payments, principal payments or both on certain municipal obligations. The underwriter of these certificates or receipts typically purchases municipal obligations and deposits the obligations in an irrevocable trust or custodial account with a custodian bank, which then issues receipts or certificates that evidence ownership of the periodic unmatured coupon payments and the final principal payment on the obligations. Although under the terms of a custodial receipt, the Fund would be typically authorized to assert its rights directly against the issuer of the underlying obligation, the Fund could be required to assert through the custodian bank those rights as may exist against the underlying issuer. Thus, in the event the underlying issuer fails to pay principal and/or interest when due, the Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation of the issuer. In addition, in the event that the trust or custodial account in which the underlying security has been deposited is determined to be an association taxable as a corporation for U.S. federal income tax purposes, the yield on the underlying security would be reduced by any entity-level corporate taxes paid by the issuer.

Custodial receipts may also evidence ownership of future interest payments, principal payments or both on certain U.S. government obligations. Such obligations are held in custody by a bank on behalf of the owners. Custodial receipts are generally not considered obligations of the U.S. government for purposes of securities laws.

With the increased use of technologies such as mobile devices and Web-based or “cloud” applications, and the dependence on the Internet and computer systems to conduct business, the Fund is susceptible to operational, information security and related risks. In general, cybersecurity incidents can result from deliberate attacks or unintentional events (arising from external or internal sources) that may cause the Fund to lose proprietary information, suffer data corruption, physical damage to a computer or network system or lose operational capacity. Cybersecurity attacks include, but are not limited to, infection by malicious software, such as malware or computer viruses or gaining unauthorized access to digital systems, networks or devices that are used to service the Fund’s operations (e.g., through “hacking,” “phishing” or malicious software coding) or other means for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cybersecurity attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on the Fund’s websites (i.e., efforts to make network services unavailable to intended users). In addition, authorized persons could inadvertently or intentionally release confidential or proprietary information stored on the Fund’s systems.

Cybersecurity incidents affecting the Fund’s Manager, the Subadviser, other service providers to the Fund or its shareholders (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) have the ability to cause disruptions and impact business operations, potentially resulting in financial losses to both the Fund and its shareholders, interference with the Fund’s ability to calculate its net asset value, impediments to trading, the inability of Fund shareholders to transact business and the Fund to process transactions (including fulfillment of Fund share purchases and redemptions), violations of applicable privacy and other laws (including the release of private shareholder information) and attendant breach notification and credit monitoring costs, regulatory fines, penalties, litigation costs, reputational damage, reimbursement or other compensation costs, forensic investigation and remediation costs, and/or additional compliance costs. Similar adverse consequences could result from cybersecurity incidents affecting issuers of securities in which the Fund invests, counterparties with which the Fund engages in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies and other financial institutions (including financial intermediaries and other service providers) and other parties. In addition, substantial costs may be incurred in order to safeguard against and reduce the risk of any cybersecurity incidents in the future. In addition to administrative, technological and procedural safeguards, the Fund’s Manager and the Subadviser have established business continuity plans in the event of, and risk management systems to prevent or reduce the impact of, such cybersecurity incidents. However, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, as well as the rapid development of new threats. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund and its shareholders. The Fund and its shareholders could be negatively impacted as a result.

Demand instruments are securities issued as floating- or variable-rate securities subject to demand features. Demand instruments usually have a stated maturity of more than one year but contain a demand feature (or “put”) that enables the holder to tender the investment at an exercise price equal to approximately the amortized cost of the instrument plus accrued interest on no more than 30 days’ notice. Variable-rate demand instruments provide for automatic establishment of a new interest rate on set dates. Floating-rate demand instruments provide for automatic adjustment of interest rates whenever a specified interest rate (e.g., the prime rate) changes. The Fund currently is permitted to purchase floating rate and variable rate obligations with demand features in accordance with requirements established by the SEC, which, among other things, permit such instruments to be deemed to have remaining maturities of 13 months or less, notwithstanding that they may otherwise have a stated maturity in excess of 13 months. Securities with ultimate maturities of greater than 13 months may be purchased only pursuant to Rule 2a-7 of the 1940 Act. Frequently, floating rate and variable rate obligations are secured by letters of credit or other credit support arrangements provided by banks.

Securities with demand features may involve certain expenses and risks, including the inability of the issuer of the instrument to pay for the securities at the time the instrument is exercised, non-marketability of the instrument and differences between the maturity of the underlying security and the maturity of the instrument. Securities may cost more with demand features than without them. Demand features can serve three purposes: (i) to shorten the maturity of a variable or floating rate security, (ii) to enhance the instrument’s credit quality and (iii) to provide a source of liquidity. Demand features are often issued by third party financial institutions, generally domestic and foreign banks, and by brokerage firms or insurance companies. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the institutions supporting the Fund’s investments and changes in the credit quality of these institutions could cause losses to the Fund and affect its share price.

Variable rate demand instruments include variable rate demand preferred shares or other forms of liquidity protected preferred shares that are issued by closed end investment companies that invest in municipal securities. These preferred shares have a liquidation preference and pay a dividend that is set weekly or at some other interval (typically 28 days) by a remarketing agent or through a similar process that is designed to approximate current prevailing interest rates. The Fund, as a holder of one of these instruments, will have the right to tender the securities for remarketing or, if the securities cannot be remarketed, to tender the securities to a liquidity provider, in each case at a price equal to its liquidation preference plus accrued dividends. The Fund would have no right to tender the shares to the issuer for payment or redemption, and the shares will be not freely transferable. The Fund will be subject to the risk that the liquidity provider will not be able to honor its unconditional commitment to purchase the shares.

The risks of investing in securities of non-U.S. issuers or issuers with significant exposure to non-U.S. markets may be related, among other things, to (i) differences in size, liquidity and volatility of, and the degree and manner of regulation of, the securities markets of certain non-U.S. markets compared to the securities markets in the U.S.; (ii) economic, political and social factors; and (iii) foreign exchange matters, such as restrictions on the repatriation of capital, fluctuations in exchange rates between the U.S. dollar and the currencies in which the Fund’s portfolio securities are quoted or denominated, exchange control regulations and costs associated with currency exchange. The political and economic structures in certain foreign countries, particularly emerging markets, are expected to undergo significant evolution and rapid development, and such countries may lack the social, political and economic stability characteristic of more developed countries.

Unanticipated political or social developments may affect the values of the Fund’s investments in such countries. The economies and securities and currency markets of many emerging markets have experienced significant disruption and declines. There can be no assurances that these economic and market disruptions will not continue.

Legal remedies available to investors in certain foreign countries may be less extensive than those available to investors in the U.S. or other foreign countries. Accounting standards in other countries are also not necessarily the same as in the United States. If the accounting standards in another country do not require as much detail as U.S. accounting standards, it may be harder for the portfolio manager to completely and accurately determine a company’s financial condition. In addition, the U.S. Government has from time to time in the past imposed restrictions, through penalties and otherwise, on foreign investments by U.S. investors such as the Fund. Also, brokerage commissions and other costs of buying or selling securities often are higher in foreign countries than they are in the U.S. This reduces the amount the Fund can earn on its investments.

The Fund generally holds its foreign securities and cash in foreign banks and securities depositories. Some foreign banks and securities depositories may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or any of their agents goes bankrupt. In addition, it is often more expensive for the Fund to buy, sell and hold securities in certain foreign markets than in the U.S. The increased expense of investing in foreign markets reduces the amount the Fund can earn on its investments and typically results in a higher operating expense ratio for the Fund as compared to investment companies that invest only in the United States.

Securities of some foreign companies have lower liquidity, and their prices are more volatile, than securities of comparable domestic companies. Certain foreign countries are known to experience long delays between the trade and settlement dates of securities purchased or sold resulting in increased exposure of the Fund to market and foreign exchange fluctuations brought about by such delays, and to the corresponding negative impact on Fund liquidity.

The U.S. dollar value of securities denominated in a foreign currency will vary with changes in currency exchange rates, which can be volatile. Accordingly, changes in the value of the currency in which the Fund’s investments are denominated relative to the U.S. dollar will affect the Fund’s net asset value. Exchange rates are generally affected by the forces of supply and demand in the international currency markets, the relative merits of investing in different countries and the intervention or failure to intervene of U.S. or foreign governments and central banks. However, currency exchange rates may fluctuate based on factors intrinsic to a country’s economy. Some emerging market countries also may have managed currencies, which are not free floating against the U.S. dollar. In addition, emerging markets are subject to the risk of restrictions upon the free conversion of their currencies into other currencies. Any devaluations relative to the U.S. dollar in the currencies in which the Fund’s securities are quoted would reduce the Fund’s net asset value per share.

A number of countries in Europe have experienced severe economic and financial difficulties. Many non-governmental issuers, and even certain governments, have defaulted on, or been forced to restructure, their debts; many other issuers have faced difficulties obtaining credit or refinancing existing obligations; financial institutions have in many cases required government or central bank support, have needed to raise capital, and/or have been impaired in their ability to extend credit; and financial markets in Europe and elsewhere have experienced extreme volatility and declines in asset values and liquidity. These difficulties may continue, worsen or spread within and outside of Europe. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not work, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences.

Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, on June 23, 2016, voters in the United Kingdom approved withdrawal from the European Union. On March 29, 2017, the United Kingdom formally notified the European Council of its intention to leave the European Union; as a result, the United Kingdom will remain a member state, subject to European Union law with privileges to provide services under the single market directives, for at least two years from that date. Given the size and importance of the United Kingdom’s economy, uncertainty about its legal, political, and economic relationship with the remaining member states of the European Union may continue to be a source of instability. Moreover, other countries may seek to withdraw from the European Union and/or abandon the euro, the common currency of the European Union. A number of countries in Europe have suffered terror attacks, and additional attacks may occur in the future. Ukraine has experienced ongoing military conflict; this conflict may expand and military attacks could occur elsewhere in Europe. Europe has also been struggling with mass migration from the Middle East and Africa.

The ultimate effects of these events and other socio-political or geopolitical issues are not known but could profoundly affect global economies and markets. Whether or not the Fund invests in securities of issuers located in Europe or with significant exposure to European issuers or countries, these events could negatively affect the value and liquidity of the Fund’s investments.

The Fund may invest in all types of debt securities of governmental issuers in all countries, including emerging markets. These sovereign debt securities may include: debt securities issued or guaranteed by governments, governmental agencies or instrumentalities and political subdivisions located in emerging market countries; debt securities issued by government owned, controlled or sponsored entities located in emerging market countries; interests issued for the purpose of restructuring the investment characteristics of instruments issued by any of the above issuers; Brady Bonds, which are debt securities issued under the framework of the Brady Plan as a means for debtor nations to restructure their outstanding external indebtedness; participations in loans between emerging market governments and financial institutions; or debt securities issued by supranational entities such as the World Bank. A supranational entity is a bank, commission or company established or financially supported by the national governments of one or more countries to promote reconstruction or development. Included among these entities are the Asian Development Bank, the European Union, the European Investment Bank, the Inter-American Development Bank, the International Monetary Fund, the United Nations, the World Bank and the European Bank for Reconstruction and Development. Supranational organizations have no taxing authority and are dependent on their members for payments of interest and principal. There is no guarantee that one or more members of a supranational organization will continue to make capital contributions. If such contributions are not made, the organization may be unable to pay interest or repay principal on its debt securities, and the Fund may lose money on such investments. Further, the lending activities of such entities are limited to a percentage of their total capital, reserves and net income.

Sovereign debt is subject to risks in addition to those relating to non-U.S. investments generally. As a sovereign entity, the issuing government may be immune from lawsuits in the event of its failure or refusal to pay the obligations when due. The debtor’s willingness or ability to repay in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign currency reserves, the availability of sufficient foreign currency exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward principal international lenders and the political constraints to which the sovereign debtor may be subject. Sovereign debtors may also be dependent on disbursements or assistance from foreign governments or multinational agencies, the country’s access to trade and other international credits, and the country’s balance of trade. Assistance may be dependent on a country’s implementation of austerity measures and reforms, economic performance and/or the timely service of such debtor’s obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties’ commitments to lend funds to the governmental entity, which may further impair such debtor’s ability or willingness to service its debts in a timely manner. Some sovereign debtors have rescheduled their debt payments, declared moratoria on payments or restructured their debt to effectively eliminate portions of it, and similar occurrences may happen in the future. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part.

High quality corporate obligations include obligations of corporations that are originally issued with a maturity of greater than 397 days and are: (1) rated as long-term debt obligations in the highest rating category or (2) issued by an issuer that has a class of short-term debt obligations that are comparable in priority and security with the obligation and that have been rated in the highest rating category for short-term debt obligations, or are otherwise comparable to short-term debt obligations having such a rating.

An illiquid security is any security which the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security. The Fund must follow strict rules with respect to the liquidity of its portfolio securities, including daily and weekly liquidity requirements. To the extent required by applicable law and SEC guidance, the Fund will not acquire an illiquid security if such acquisition would cause the aggregate value of illiquid securities to exceed 5% of the Fund’s total assets. If at any time the portfolio manager determines that the value of illiquid securities held by the Fund exceeds 5% of the Fund’s total assets, the portfolio manager will take such steps as it considers appropriate to reduce the percentage as soon as reasonably practicable.

Restricted securities are securities subject to legal or contractual restrictions on their resale, such as private placements. Such restrictions might prevent the sale of restricted securities at a time when the sale would otherwise be

desirable. Under SEC regulations, certain restricted securities acquired through private placements can be traded freely among qualified purchasers. While restricted securities are generally presumed to be illiquid, it may be determined that a particular restricted security is liquid. Investing in these restricted securities could have the effect of increasing the Fund’s illiquidity if qualified purchasers become, for a time, uninterested in buying these securities.

Restricted securities may be sold only (1) pursuant to SEC Rule 144A or another exemption, (2) in privately negotiated transactions or (3) in public offerings with respect to which a registration statement is in effect under the 1933 Act. Rule 144A securities, although not registered in the U.S., may be sold to qualified institutional buyers in accordance with Rule 144A under the 1933 Act. As noted above, the Fund may determine that some Rule 144A securities are liquid. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a restricted security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than prevailed when it decided to sell.

Illiquid securities may be difficult to value, and the Fund may have difficulty disposing of such securities promptly. The Fund does not consider non-U.S. securities to be restricted if they can be freely sold in the principal markets in which they are traded, even if they are not registered for sale in the U.S.

Certain investment companies, including those that are affiliated with the Fund because they are managed by the Manager or an affiliate of the Manager, may invest in the Fund and may at times have substantial investments in one or more funds. Other investors also may at times have substantial investments in one or more funds.

From time to time, the Fund may experience relatively large redemptions or investments due to transactions in fund shares by a fund or other significant investor. The effects of these transactions could adversely affect the Fund’s performance. In the event of such redemptions or investments, the Fund could be required to sell securities or to invest cash at a time when it is not advantageous to do so. Such transactions may increase brokerage and/or other transaction costs of the Fund. A large redemption could cause the Fund’s expenses to increase and could result in the Fund becoming too small to be economically viable. Redemptions of fund shares could also accelerate the realization of taxable capital gains in the Fund if sales of securities result in capital gains. The impact of these transactions is likely to be greater when a fund or other significant investor purchases, redeems, or owns a substantial portion of the Fund’s shares.

The Manager and the Subadviser are subject to potential conflicts of interest in connection with investments in the Fund by an affiliated fund due to their affiliation. For example, the Manager or the Subadviser could have the incentive to permit an affiliated fund to become a more significant shareholder (with the potential to cause greater disruption) than would be permitted for an unaffiliated investor. Investments by an affiliated fund may also give rise to conflicts in connection with the voting of fund shares. The Manager, the Subadviser and/or its advisory affiliates intend to seek to address these potential conflicts of interest in the best interests of the Fund’s shareholders, although there can be no assurance that such efforts will be successful. The Manager and the Subadviser will consider how to minimize potential adverse impacts of affiliated fund investments, and, may take such actions as each deems appropriate to address potential adverse impacts, including redemption of shares in-kind, rather than in cash.

London Interbank Offered Rate (“LIBOR”) Replacement and Other Reference Rates Risk

Many debt securities, derivatives, and other financial instruments, including some of the Fund’s investments, utilize benchmark or reference rates such as LIBOR, European Interbank Offer Rate (“EURIBOR”), Sterling Overnight Interbank Average Rate (“SONIA”), and other similar types of reference rates for variable interest rate calculations. Instruments in which the Fund invests may pay interest at floating rates based on LIBOR or other similar types of reference rates or may be subject to interest caps or floors based on such reference rates. The Fund and issuers of instruments in which the Fund invests may also obtain financing at floating rates based on such reference rates. The elimination of a reference rate or any other changes or reforms to the determination or supervision of reference rates could have an adverse impact on the market for—or value of—any securities or payments linked to those reference rates.

The use of LIBOR came under pressure following manipulation allegations in 2012. Despite increased regulation and other corrective actions since that time, concerns have arisen regarding its viability as a benchmark due largely to reduced

activity in the financial markets that it measures. In 2017, the U.K. Financial Conduct Authority announced that it will no longer encourage nor require banks to submit rates for the calculation of LIBOR after 2021. Such announcement indicates that the continuation of LIBOR cannot be guaranteed after 2021. It is unclear whether LIBOR will continue to exist in its current or a modified form. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies. Based on the recommendations of the New York Federal Reserve’s Alternative Reference Rate Committee (comprised of major derivative market participants and their regulators), the U.S. Federal Reserve began publishing a Secured Overnight Funding Rate (“SOFR”) that is intended to replace U.S. Dollar LIBOR. Proposals for alternative reference rates for other currencies have also been announced or have already begun publication, such as SONIA in the United Kingdom.

Markets are slowly developing in response to these new rates, and transition planning is at a relatively early stage. Neither the effect of the transition process nor its ultimate success is known. The transition process may lead to increased volatility and illiquidity in markets that currently rely on LIBOR to determine interest rates. The effect of any changes to—or discontinuation of—LIBOR on the Fund will vary depending on, among other things, provisions in individual contracts and whether, how, and when industry participants develop and adopt new reference rates and alternative reference rates for both legacy and new products and instruments. Because the usefulness of LIBOR as a benchmark may deteriorate during the transition period, these effects could materialize prior to the end of 2021.

Money market instruments are short-term IOUs issued by banks or other non-governmental issuers, the U.S. or non-U.S. governments, or state or local governments. Money market instruments generally have maturity dates of 13 months or less, and may pay interest at fixed, floating or adjustable rates, or may be issued at a discount. Money market instruments may include certificates of deposit, bankers’ acceptances, variable rate demand securities (where the interest rate is reset periodically and the holder may demand payment from the issuer or another obligor at any time), preferred shares, fixed-term obligations, commercial paper (short-term unsecured debt), asset-backed commercial paper, other mortgage-backed and asset-backed securities and repurchase agreements. Asset-backed commercial paper refers to a debt security with an original term to maturity of up to 270 days that may be backed by residential and commercial mortgage loans or mortgage-backed securities or other types of receivables. Payments due on asset-backed commercial paper are supported by cash flows from underlying assets, or one or more liquidity or credit support providers, or both.

An asset-backed security is a fixed income security that derives its value primarily from cash flows relating to a pool of assets. There are a number of different types of asset-backed and related securities, including mortgage-backed securities, securities backed by other pools of collateral (such as automobile loans, student loans, sub-prime mortgages, and credit card receivables), collateralized mortgage obligations, and collateralized debt obligations.

Asset-backed and mortgage-backed securities differ from conventional bonds in that principal is paid over the life of the securities rather than at maturity. As a result, payments of principal of and interest on mortgage-backed securities and asset-backed securities are made more frequently than are payments on conventional debt securities. The average life of asset-backed and mortgage-backed securities is likely to be substantially less than the original maturity of the underlying asset pools as a result of prepayments or foreclosures of mortgages, as applicable. In addition, holders of mortgage-backed securities and of certain asset-backed securities (such as asset-backed securities backed by home equity loans) may receive unscheduled payments of principal at any time representing prepayments on the underlying mortgage loans or financial assets. When the holder of the security attempts to reinvest prepayments or even the scheduled payments of principal and interest, it may receive a rate of interest that is higher or lower than the rate on the mortgage-backed security or asset-backed security originally held. To the extent that mortgage-backed securities or asset-backed securities are purchased by the Fund at a premium, mortgage foreclosures and principal prepayments may result in a loss to the extent of the premium paid. To the extent the loans underlying a security representing an interest in a pool of mortgages or other assets are prepaid, the Fund may experience a loss (if the price at which the respective security was acquired by the Fund was at a premium over par, which represents the price at which the security will be redeemed upon prepayment) or a gain (if the price at which the respective security was acquired by the Fund was at a discount from par). In addition, prepayments of such securities held by the Fund will reduce the share price of the Fund to the extent the market value of the securities at the time of prepayment exceeds their par value, and will increase the share price of the Fund to the extent the par value of the securities exceeds their market value at the time of prepayment. Prepayments may occur with greater frequency in periods of declining interest rates because, among other reasons, it may be possible for

borrowers to refinance their outstanding obligation at lower interest rates. When market interest rates increase, the market values of asset-backed and mortgage-backed securities decline. At the same time, however, refinancing slows, which lengthens the effective maturities of these securities. As a result, the negative effect of the rate increase on the market value of asset-backed and mortgage-backed securities is usually more pronounced than it is for other types of fixed income securities.

Changes in the market’s perception of the mortgages or assets backing the security, the creditworthiness of the servicing agent for the loan pool, the originator of the loans, or the financial institution providing any credit enhancement, will all affect the value of an asset-backed or mortgage-backed security, as will the exhaustion of any credit enhancement.

The risks of investing in asset-backed and mortgage-backed securities ultimately depend upon the payment of the underlying loans by the individual borrowers. In its capacity as purchaser of an asset-backed security or mortgage-backed security, the Fund would generally have no recourse to the entity that originated the loans in the event of default by the borrower. The risk of non-payment is greater for asset-backed and mortgage-backed securities that are backed by pools that contain subprime loans, but a level of risk exists for all loans. Market factors adversely affecting loan repayments may include a general economic turndown and high unemployment. Mortgage-backed securities may be adversely affected by a general slowdown in the real estate market, a drop in the market prices of real estate, or an increase in interest rates resulting in higher mortgage payments by holders of adjustable rate mortgages.

Additional information regarding different types of asset-backed and mortgage-backed securities is provided below. Governmental, government-related or private entities may create pools of loan assets offering pass-through investments in addition to those described below. As new types of asset-backed or mortgage-backed securities are developed and offered to investors, the portfolio manager may, consistent with the Fund’s investment objective and policies, consider making investments in such new types of securities.

Mortgage-Backed Securities. Mortgage-backed securities (“MBS”) represent interests in pools of mortgage loans made by lenders such as savings and loan institutions, mortgage bankers, commercial banks and others, to finance purchases of homes, commercial buildings or other real estate. The individual mortgage loans are assembled for sale to investors (such as the Fund) by various governmental or government-related agencies and private organizations, such as dealers.

Government-sponsored MBS. Some government sponsored mortgage-related securities are backed by the full faith and credit of the United States. The Government National Mortgage Association (“Ginnie Mae”), the principal guarantor of such securities, is a wholly owned United States government corporation within the Department of Housing and Urban Development. Other government-sponsored mortgage-related securities are not backed by the full faith and credit of the United States government. Issuers of such securities include Fannie Mae (formally known as the Federal National Mortgage Association) and Freddie Mac (formally known as the Federal Home Loan Mortgage Corporation). Fannie Mae is a government-sponsored corporation which is subject to general regulation by the Secretary of Housing and Urban Development. Pass-through securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae. Freddie Mac is a stockholder-owned corporation chartered by Congress and subject to general regulation by the Department of Housing and Urban Development. Participation certificates representing interests in mortgages from Freddie Mac’s national portfolio are guaranteed as to the timely payment of interest and ultimate collection of principal by Freddie Mac. The U.S. government has provided financial support to Fannie Mae and Freddie Mac in the past, but there can be no assurances that it will support these or other government-sponsored entities in the future.

Under the Federal Housing Finance Agency’s “Single Security Initiative,” Fannie Mae and Freddie Mac have entered into a joint initiative to develop a common securitization platform for the issuance of Uniform Mortgage-Backed Securities (“UMBS”), which would generally align the characteristics of Fannie Mae and Freddie Mac participation certificates. In June 2019 Fannie Mae and Freddie Mac are expected to begin issuing UMBS in place of their current offerings of “to be announced”-eligible mortgage-backed securities. The effect of the issuance of UMBS on the market for mortgage-backed securities is uncertain.

Privately Issued MBS. Unlike MBS issued or guaranteed by the U.S. government or certain government-sponsored entities, MBS issued by private issuers do not have a government or government-sponsored entity guarantee, but may have credit enhancement provided by external entities such as banks or financial institutions or achieved through the structuring of the transaction itself.

In addition, MBS that are issued by private issuers are not subject to the underwriting requirements for the underlying mortgages that are applicable to those MBS that have a government or government-sponsored entity guarantee. As a result, the mortgage loans underlying private MBS may, and frequently do, have less favorable collateral, credit risk or other underwriting characteristics than government or government-sponsored MBS and have wider variances in a number of terms including interest rate, term, size, purpose and borrower characteristics. Privately issued pools more frequently include second mortgages, high loan-to-value mortgages and manufactured housing loans. The coupon rates and maturities of the underlying mortgage loans in a private-label MBS pool may vary to a greater extent than those included in a government guaranteed pool, and the pool may include subprime mortgage loans. Subprime loans refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. For these reasons, the loans underlying these securities have had in many cases higher default rates than those loans that meet government underwriting requirements.

Privately issued mortgage-backed securities are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-backed securities held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans.

Adjustable rate mortgage-backed securities. Adjustable rate mortgage-backed securities (“ARMBS”) are pass-through securities collateralized by mortgages with adjustable rather than fixed rates. Adjustable rate mortgages eligible for inclusion in a mortgage pool generally provide for a fixed initial mortgage interest rate for a set number of scheduled monthly payments. After that schedule of payments has been completed, the interest rates of the adjustable rate mortgages are subject to periodic adjustment based on changes to a designated benchmark index.

Mortgages underlying most ARMBS may contain maximum and minimum rates beyond which the mortgage interest rate may not vary over the lifetime of the mortgage. In addition, certain adjustable rate mortgages provide for additional limitations on the maximum amount by which the mortgage interest rate may adjust for any single adjustment period. In the event that market rates of interest rise more rapidly to levels above that of the maximum rate for the adjustable rate mortgages underlying an ARMBS, the ARMBS’ coupon may represent a below market rate of interest. In these circumstances, the market value of the ARMBS will likely have fallen. During periods of declining interest rates, income to the Fund derived from adjustable rate mortgages that remain in the mortgage pool underlying the ARMBS may decrease in contrast to the income on fixed rate mortgages, which will remain constant. Adjustable rate mortgages also have less potential for appreciation in value as interest rates decline than do fixed rate investments. In addition, the current yields on ARMBS may be different than market yields during interim periods between coupon reset dates.

Stripped mortgage-backed securities. Stripped mortgage-backed securities (“SMBS”) are structured with two or more classes of securities that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMBS will have at least one class receiving only a small portion of the principal. In the most extreme case, one class will receive all of the interest (“IO” or interest-only class), while the other class will receive all of the principal (“PO” or principal-only class). The yield to maturity on IOs, POs and other mortgage-backed securities that are purchased at a substantial premium or discount generally are extremely sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on such securities’ yield to maturity. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities even if the securities have received the highest rating by a NRSRO.

SMBS have greater volatility than other types of securities. Although SMBS are purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers, the market for such securities has not yet been fully developed. Accordingly, the secondary market for SMBS may be more volatile and have lower liquidity than that for other MBS, potentially limiting the Fund’s ability to buy or sell SMBS at any particular time.

Collateralized mortgage obligations. Another type of security representing an interest in a pool of mortgage loans is known as a collateralized mortgage obligation (“CMO”). CMOs represent interests in a short-term, intermediate-term or long-term portion of a mortgage pool. Each portion of the pool receives monthly interest payments, but the principal repayments pass through to the short-term CMO first and to the long-term CMO last. A CMO permits an investor to more accurately predict the rate of principal repayments. CMOs are issued by private issuers, such as broker-dealers, and by government agencies, such as Fannie Mae and Freddie Mac. Investments in CMOs are subject to the same risks as direct investments in the underlying

mortgage-backed securities. In addition, in the event of a bankruptcy or other default of a broker that issued the CMO held by the Fund, the Fund could experience delays in liquidating both its position and losses. The Fund may invest in CMOs in any rating category of the recognized rating services and may invest in unrated CMOs. The Fund may also invest in “stripped” CMOs, which represent only the income portion or the principal portion of the CMO. The values of stripped CMOs are very sensitive to interest rate changes; accordingly, these instruments present a greater risk of loss than conventional mortgage-backed securities.

Tiered index bonds. Tiered index bonds are relatively new forms of mortgage-related securities. The interest rate on a tiered index bond is tied to a specified index or market rate. So long as this index or market rate is below a predetermined “strike” rate, the interest rate on the tiered index bond remains fixed. If, however, the specified index or market rate rises above the “strike” rate, the interest rate of the tiered index bond will decrease. Thus, under these circumstances, the interest rate on a tiered index bond, like an inverse floater, will move in the opposite direction of prevailing interest rates, with the result that the price of the tiered index bond would decline and may be considerably more volatile than that of a fixed-rate bond.

Similar to mortgage-backed securities, other types of asset-backed securities may be issued by agencies or instrumentalities of the U.S. government (including those whose securities are neither guaranteed nor insured by the U.S. government), foreign governments (or their agencies or instrumentalities), or non-governmental issuers. These securities include securities backed by pools of automobile loans, educational loans, home equity loans, and credit card receivables. The underlying pools of assets are securitized through the use of trusts and special purpose entities. These securities may be subject to the risks described above under “Mortgage-Backed and Other Asset-Backed Securities — General,” including risks associated with changes in interest rates and prepayment of underlying obligations.

Certain types of asset-backed securities present additional risks that are not presented by mortgage-backed securities. In particular, certain types of asset-backed securities may not have the benefit of a security interest in the related assets. For example, many securities backed by credit card receivables are unsecured. Even when security interests are present, the ability of an issuer of certain types of asset-backed securities to enforce those interests may be more limited than that of an issuer of mortgage-backed securities. For instance, automobile receivables generally are secured by automobiles rather than by real property. Most issuers of automobile receivables permit loan servicers to retain possession of the underlying assets. In addition, because of the large number of underlying vehicles involved in a typical issue of asset-backed securities and technical requirements under state law, the trustee for the holders of the automobile receivables may not have a proper security interest in all of the automobiles. Therefore, recoveries on repossessed automobiles may not be available to support payments on these securities.

In addition, certain types of asset-backed securities may experience losses on the underlying assets as a result of certain rights provided to consumer debtors under federal and state law. In the case of certain consumer debt, such as credit card debt, debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on their credit cards (or other debt), thereby reducing their balances due. For instance, a debtor may be able to offset certain damages for which a court has determined that the creditor is liable to the debtor against amounts owed to the creditor by the debtor on his or her credit card.

Additionally, an asset-backed security is subject to risks associated with the servicing agent’s or originator’s performance. For example, a servicing agent or originator’s mishandling of documentation related to the underlying collateral (e.g., failure to properly document a security interest in the underlying collateral) may affect the rights of the security holders in and to the underlying collateral.

Asset-backed commercial paper. The Fund may purchase commercial paper, including asset-backed commercial paper (“ABCP”) that is issued by structured investment vehicles or other conduits. These conduits may be sponsored by mortgage companies, investment banking firms, finance companies, hedge funds, private equity firms and special purpose finance entities. ABCP typically refers to a debt security with an original term to maturity of up to 270 days, the payment of which is supported by cash flows from underlying assets, or one or more liquidity or credit support providers, or both. Assets backing ABCP, which may be included in revolving pools of assets with large numbers of obligors, include credit card, car loan and other consumer receivables and home or commercial mortgages, including subprime mortgages. The repayment of ABCP issued by a conduit depends primarily on the cash collections received from the conduit’s underlying asset portfolio and the conduit’s ability to issue new ABCP. Therefore, there could be losses to the Fund investing in ABCP in the event of credit or market value deterioration in

the conduit’s underlying portfolio, mismatches in the timing of the cash flows of the underlying asset interests and the repayment obligations of maturing ABCP, or the conduit’s inability to issue new ABCP. To protect investors from these risks, ABCP programs may be structured with various protections, such as credit enhancement, liquidity support, and commercial paper stop-issuance and wind-down triggers. However there can be no guarantee that these protections will be sufficient to prevent losses to investors in ABCP.

Some ABCP programs provide for an extension of the maturity date of the ABCP if, on the related maturity date, the conduit is unable to access sufficient liquidity through the issue of additional ABCP. This may delay the sale of the underlying collateral and the Fund may incur a loss if the value of the collateral deteriorates during the extension period. Alternatively, if collateral for ABCP deteriorates in value, the collateral may be required to be sold at inopportune times or at prices insufficient to repay the principal and interest on the ABCP. ABCP programs may provide for the issuance of subordinated notes as an additional form of credit enhancement. The subordinated notes are typically of a lower credit quality and have a higher risk of default. A fund purchasing these subordinated notes will therefore have a higher likelihood of loss than investors in the senior notes.

Municipal securities (which are also referred to herein as “municipal obligations” or “municipal bonds”) generally include debt obligations (including, but not limited to bonds, notes or commercial paper) issued by or on behalf of any of the 50 U.S. states and their political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) or other qualifying issuers, participations or other interests in these securities and other related investments. The interest paid on municipal securities is generally excluded from gross income for regular U.S. federal income tax purposes, although it may be subject to the U.S. federal alternative minimum tax (“AMT”). The Fund does not anticipate holding municipal securities in sufficient quantities to qualify to pay exempt-interest dividends and, as a result, distributions to shareholders are expected to be treated for federal income tax purposes as ordinary dividends without regard to the character of any interest that was received on municipal securities.

Municipal securities are issued to obtain funds for various public purposes, including the construction of a wide range of public facilities, such as airports, bridges, highways, housing, hospitals, mass transportation, schools, streets, water and sewer works, gas, and electric utilities. They may also be issued to refund outstanding obligations, to obtain funds for general operating expenses, or to obtain funds to loan to other public institutions and facilities and in anticipation of the receipt of revenue or the issuance of other obligations.

The two principal classifications of municipal securities are “general obligation” securities and “limited obligation” or “revenue” securities. General obligation securities are secured by a municipal issuer’s pledge of its full faith, credit, and taxing power for the payment of principal and interest. Accordingly, the capacity of the issuer of a general obligation bond to pay interest and repay principal when due is affected by the issuer’s maintenance of its tax base. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source. Accordingly, the timely payment of interest and the repayment of principal in accordance with the terms of the revenue security is a function of the economic viability of the facility or revenue source. Revenue securities include private activity bonds which are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved. Municipal securities may also include “moral obligation” bonds, which are normally issued by special purpose public authorities. If the issuer of moral obligation bonds is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer.

Private Activity Bonds. Private activity bonds are issued by or on behalf of public authorities to provide funds, usually through a loan or lease arrangement, to a private entity for the purpose of financing construction of privately operated industrial facilities, such as warehouse, office, plant and storage facilities and environmental and pollution control facilities. Such bonds are secured primarily by revenues derived from loan repayments or lease payments due from the entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. Therefore, repayment of such bonds generally depends on the revenue of a private entity. The continued ability of an entity to generate sufficient revenues for the payment of principal and interest on such bonds will be affected by many factors, including the size of the entity, its capital structure, demand for its products or services, competition,

general economic conditions, government regulation and the entity’s dependence on revenues for the operation of the particular facility being financed.

Under U.S. federal income tax law, interest on municipal bonds issued after August 7, 1986 which are specified private activity bonds, and the proportionate share of any exempt-interest dividend paid by a regulated investment company that receives interest from such private activity bonds, will be treated as an item of tax preference for purposes of the AMT. For regular U.S. federal income tax purposes such interest is tax-exempt. Bonds issued in 2009 and 2010 generally will not be treated as private activity bonds, and interest earned on such bonds generally will not be treated as a tax preference item.

Industrial Development Bonds. Industrial development bonds (“IDBs”) are issued by public authorities to obtain funds to provide financing for privately-operated facilities for business and manufacturing, housing, sports, convention or trade show facilities, airport, mass transit, port and parking facilities, air or water pollution control facilities, and certain facilities for water supply, gas, electricity or sewerage or solid waste disposal. Although IDBs are issued by municipal authorities, the payment of principal and interest on IDBs is dependent solely on the ability of the user of the facilities financed by the bonds to meet its financial obligations and the pledge, if any, of the real and personal property being financed as security for such payments. IDBs are considered municipal securities if the interest paid is exempt from regular federal income tax. Interest earned on IDBs may be subject to the AMT.

Tender Option Bonds. Tender option bonds represent securities issued by a special purpose trust formed for the purpose of holding securities (typically municipal bonds or other municipal securities) that are contributed to the trust by the Fund or another third party. The trust typically issues two classes of securities: short-term floating rate interests (sometimes known as “put bonds” or “puttable securities”), which are generally sold to third party investors (often money market funds), and residual interests (also referred to as “inverse floaters”), which are generally held by the Fund that contributed securities to the trust. The short-term floating rate interests typically have first priority on the cash flow from the municipal bonds or other securities held by the trust, and the remaining cash flow less certain expenses is paid to holders of the residual interests. If the Fund is the seller of the municipal bonds or other securities to the trust, it receives the proceeds from the trust’s sale of the floating rate interests, less certain transaction costs. These proceeds are frequently used by the Fund to invest in other securities, which generates leverage for the Fund.

Residual interests in tender option bond trusts in which the Fund will invest will pay interest or income that, in the opinion of counsel to the applicable trust, is exempt from regular U.S. federal income tax. Neither the Fund, nor the Manager, nor the Subadviser will conduct its own analysis of the tax status of the interest or income paid by residual interest held by the Fund, but will rely on the opinion of counsel to the applicable trust.

Typically, a liquidity provider is engaged to purchase the short-term floating rate interests at their original purchase price upon the occurrence of certain events, such as the failure to remarket a certain percentage of the floating rate interests in a timely fashion, the downgrading (but typically not below investment grade or in connection with events indicating that bankruptcy of the issuer may be likely) of the bonds held by the tender option bond trust, or certain regulatory or tax events. A fund participating in a tender option bond transaction will bear the fees paid to the liquidity provider for providing the put option to the holders of the floating rate interests. If the liquidity provider acquires the floating rate interests upon the occurrence of an event described above, the liquidity provider generally will be entitled to an in-kind distribution of the municipal bonds or other securities held by the tender option bond trust or to cause the tender option bond trust to sell the securities and distribute the proceeds to the liquidity provider.

Tender option bond transactions may be effected on a recourse or non-recourse basis. In a recourse transaction, the Fund typically enters into an agreement, requiring the Fund to pay the liquidity provider an amount equal to any loss suffered by the liquidity provider in connection with the transactions described above. The net economic effect of this agreement is to treat the Fund as though it had entered into a special type of reverse repurchase agreement pursuant to which the Fund is required to repurchase the municipal bonds or other securities upon the occurrence of certain events (such as a downgrading of securities held by the trust or a failed remarketing of the floating rate interests, which would most likely be due to an adverse change in interest rates) but not others (such as a default of the securities held by the trust). Such an arrangement may expose the Fund to a risk of loss that exceeds its investment in the tender option bond residual interests.

In a non-recourse transaction, the Fund would not be required to pay the liquidity provider in the event that it suffers a loss. However, the Fund might incur a loss if the liquidity provider liquidates the tender option bond trust at an inopportune time.

Even if a tender option bond transaction was entered into on a non-recourse basis, under certain circumstances it might be in the Fund’s interest to later agree to a recourse arrangement in order to prevent the liquidity provider from terminating the trust at that time.

Transactions in the short-term floating rate interests of tender option bonds are generally facilitated by a remarketing agent for the tender option bond trust, which sets an interest rate for the securities, typically on a weekly basis. Holders of the floating rate securities usually have the right to require the trust or a specified third party acting as agent for the trust (such as the liquidity provider) to purchase the bonds, usually at par, at a certain time or times prior to maturity or upon the occurrence of specified events or conditions. The put option or tender option right is typically available to the investor on a periodic (daily, weekly or monthly) basis. Typically, the put option is exercisable on dates on which the interest rate changes. A failure to remarket typically requires the liquidity provider to purchase the floating rate interests and in turn the liquidity provider may have recourse to the tender option bond trust and to the Fund, as described above. A fund participating in a tender option bond transaction will also bear the fees paid to the remarketing agent and or tender agent for providing services to the tender option bond trust.

If the Fund purchases all or a portion of the short-term floating rate securities sold by the trust, it is usually permitted to surrender those short-term floating rate securities together with a proportionate amount of residual interests to the trustee of the trust in exchange for a proportionate amount of the municipal bonds or other securities held by the trust.

On December 10, 2013, U.S. regulators published final rules implementing section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Volcker Rule”), which prohibit banking entities from engaging in proprietary trading of certain instruments and limit such entities’ investments in, and relationships with, “covered funds, as defined in the rules.” These rules may preclude banking entities and their affiliates from (i) sponsoring tender option bond trust programs (as such programs were then structured) and (ii) continuing relationships with or services for such tender option bond trust programs. In response to the Volcker Rule, industry participants have developed alternative structures for tender option bond financings in which service providers are engaged to assist with establishing, structuring and sponsoring tender option bond trusts. The service providers, such as administrators, liquidity providers, trustees and remarketing agents act at the direction of, and as agent of, the Fund holding residual interests of the tender option bond trust. This new tender option bond structure and any other strategies that may be developed to address the Volcker Rule may be more or less advantageous to the Fund than obtaining leverage through existing tender option bond transactions. As the Volcker Rule’s final compliance date was July 17, 2017, its ultimate impact on the tender option bond market and the municipal securities market generally is not yet known.

Tender option bond transactions constitute an important component of the municipal bond market. Accordingly, implementation of the Volcker Rule may adversely impact the municipal market, including through reduced demand for and liquidity of municipal bonds and increased financing costs for municipal issuers. Any such developments could adversely affect the Fund. The ultimate impact of these rules on the tender option bond market and the overall municipal market is not yet certain.

Municipal Leases. Municipal leases or installment purchase contracts are issued by a U.S. state or local government to acquire equipment or facilities. Municipal leases frequently have special risks not normally associated with general obligation bonds or revenue bonds. Many leases include “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. Although the obligations are typically secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might, in some cases, prove difficult or, if sold, may not fully cover the Fund’s exposure.

Participation Interests. Tax-exempt participation interests in municipal obligations (such as private activity bonds and municipal lease obligations) are typically issued by a financial institution. A participation interest gives the Fund an undivided interest in the municipal obligation in the proportion that the Fund’s participation interest bears to the total principal amount of the municipal obligation. Participation interests in municipal obligations may be backed by an irrevocable letter of credit or guarantee of, or a right to put to, a bank (which may be the bank issuing the participation interest, a bank issuing a confirming letter of credit to that of the issuing bank, or a bank serving as agent of the issuing bank with respect to the possible repurchase of the participation interest) or insurance policy of an insurance company. The Fund has the right to sell the participation interest back to the institution or draw on the letter of credit or insurance after a specified period of notice, for all or any part of the full principal amount of the Fund’s participation in the security, plus accrued interest.

Issuers of participation interests will retain a service and letter of credit fee and a fee for providing the liquidity feature, in an amount equal to the excess of the interest paid on the instruments over the negotiated yield at which the participations were purchased on behalf of the Fund. The issuer of the participation interest may bear the cost of insurance backing the participation interest, although the Fund may also purchase insurance, in which case the cost of insurance will be an expense of the Fund. Participation interests may be sold prior to maturity. Participation interests may include municipal lease obligations. Purchase of a participation interest may involve the risk that the Fund will not be deemed to be the owner of the underlying municipal obligation for purposes of the ability to claim tax exemption of interest paid on that municipal obligation.

Municipal Notes. There are four major varieties of municipal notes: Tax and Revenue Anticipation Notes (“TRANs”); Tax Anticipation Notes (“TANs”); Revenue Anticipation Notes (“RANs”); and Bond Anticipation Notes (“BANs”). TRANs, TANs and RANs are issued by U.S. states, municipalities and other tax-exempt issuers to finance short-term cash needs or, occasionally, to finance construction. Many TRANs, TANs and RANs are general obligations of the issuing entity payable from taxes or designated revenues, respectively, expected to be received within the related fiscal period. BANs are issued with the expectation that their principal and interest will be paid out of proceeds from renewal notes or bonds to be issued prior to the maturity of the BANs. BANs are issued most frequently by both general obligation and revenue bond issuers usually to finance such items as land acquisition, facility acquisition and/or construction and capital improvement projects.

Tax-Exempt Commercial Paper. Tax-exempt commercial paper is a short-term obligation with a stated maturity of 270 days or less. It is issued by state and local governments or their agencies to finance seasonal working capital needs or as short-term financing in anticipation of longer term financing. Although tax-exempt commercial paper is intended to be repaid from general revenues or refinanced, it frequently is backed by a letter of credit, lending arrangement, note repurchase agreement or other credit facility agreement offered by a bank or financial institution.

Demand Instruments. Municipal bonds may be issued as floating- or variable-rate securities subject to demand features (“demand instruments”). Demand instruments usually have a stated maturity of more than one year but contain a demand feature (or “put”) that enables the holder to redeem the investment. Variable-rate demand instruments provide for automatic establishment of a new interest rate on set dates. Floating-rate demand instruments provide for automatic adjustment of interest rates whenever a specified interest rate (e.g., the prime rate) changes.

These floating and variable rate instruments are payable upon a specified period of notice which may range from one day up to one year. The terms of the instruments provide that interest rates are adjustable at intervals ranging from daily to up to one year and the adjustments are based upon the prime rate of a bank or other appropriate interest rate adjustment index as provided in the respective instruments. Variable rate instruments include participation interests in variable- or fixed-rate municipal obligations owned by a bank, insurance company or other financial institution or affiliated organizations. Although the rate of the underlying municipal obligations may be fixed, the terms of the participation interest may result in the Fund receiving a variable rate on its investment.

Because of the variable nature of the instruments when prevailing interest rates decline, the yield on these instruments generally will decline. On the other hand, during periods when prevailing interest rates increase, the yield on these instruments generally will increase and the instruments will have less risk of capital depreciation than instruments bearing a fixed rate of return.

Stand-By Commitments. Under a stand-by commitment a dealer agrees to purchase, at the Fund’s option, specified municipal obligations held by the Fund at a specified price and, in this respect, stand-by commitments are comparable to put options. A stand-by commitment entitles the holder to achieve same day settlement and to receive an exercise price equal to the amortized cost of the underlying security plus accrued interest, if any, at the time of exercise. The Fund will be subject to credit risk with respect to an institution providing a stand-by commitment and a decline in the credit quality of the institution could cause losses to the Fund.

The Fund will generally acquire stand-by commitments to facilitate fund liquidity. The cost of entering into stand-by commitments will increase the cost of the underlying municipal obligation and similarly will decrease such security’s yield to investors. Gains, if any, realized in connection with stand-by commitments will be taxable.

Taxable Municipal Obligations. The market for U.S. taxable municipal obligations is relatively small, which may result in a lack of liquidity and in price volatility of those securities. Interest on taxable municipal obligations is includable in gross income for regular U.S. federal income tax purposes. While interest on taxable municipal obligations may be exempt from

personal taxes imposed by the U.S. state within which the obligation is issued, such interest will nevertheless generally be subject to all other U.S. state and local income and franchise taxes.

Tax Risk. The Code imposes certain continuing requirements on issuers of tax-exempt bonds regarding the use, expenditure and investment of bond proceeds and the payment of rebates to the U.S. government. Failure by the issuer to comply after the issuance of tax-exempt bonds with certain of these requirements could cause interest on the bonds to become includable in gross income retroactive to the date of issuance.

From time to time, proposals have been introduced before the U.S. Congress for the purpose of restricting or eliminating the U.S. federal income tax exemption for interest on municipal obligations. In this regard, for bonds issued after December 31, 2017, the tax-advantaged treatment previously available to “tax credit bonds” and “advance refunding bonds” is no longer available. Further, similar proposals may be introduced in the future. In addition, the U.S. federal income tax exemption has been, and may in the future be, the subject of litigation. If one of these proposals were enacted, or if any such litigation were adversely decided, the availability of tax-exempt obligations for investment by the Fund and the value of the Fund’s investments could be affected.

Opinions relating to the validity of municipal obligations and to the exclusion of interest thereon from gross income for regular federal and/or state income tax purposes are rendered by bond counsel to the respective issuers at the time of issuance. The Fund and its service providers will rely on such opinions and will not review the proceedings relating to the issuance of municipal obligations or the bases for such opinions.

Information Risk. Information about the financial condition of issuers of municipal obligations may be less available than about corporations whose securities are publicly traded.

U.S. State and Federal Law Risk. Municipal obligations are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the U.S. federal Bankruptcy Code, and laws, if any, that may be enacted by the U.S. Congress or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. There is also the possibility that, as a result of litigation or other conditions, the power or ability of any one or more issuers to pay, when due, the principal of and interest on its or their municipal obligations may be materially affected.

Market and Ratings Risk. The yields on municipal obligations are dependent on a variety of factors, including economic and monetary conditions, general market conditions, supply and demand, general conditions of the municipal market, size of a particular offering, the maturity of the obligation and the rating of the issue. Adverse economic, business, legal or political developments might affect all or substantial portions of the Fund’s municipal obligations in the same manner.

Unfavorable developments in any economic sector may have far-reaching ramifications for the municipal market overall or any state’s municipal market. Although the ratings of tax-exempt securities by ratings agencies are relative and subjective, and are not absolute standards of quality, such ratings reflect the assessment of the ratings agency, at the time of issuance of the rating, of the economic viability of the issuer of a general obligation bond or, with respect to a revenue bond, the special revenue source, with respect to the timely payment of interest and the repayment of principal in accordance with the terms of the obligation, but do not reflect an assessment of the market value of the obligation. See Appendix B for additional information regarding ratings. Consequently, municipal obligations with the same maturity, coupon and rating may have different yields when purchased in the open market, while municipal obligations of the same maturity and coupon with different ratings may have the same yield.

Risks Associated with Sources of Liquidity or Credit Support. Issuers of municipal obligations may employ various forms of credit and liquidity enhancements, including letters of credit, guarantees, swaps, puts and demand features, and insurance, provided by U.S. or non-U.S. entities such as banks and other financial institutions. Changes in the credit quality of the entities providing the enhancement could affect the value of the securities or the Fund’s share price. U.S. banks and certain financial institutions are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments which may be made and interest rates and fees which may be charged. Non-U.S. banks and financial institutions may be less regulated than their U.S. counterparts and may be subject to additional risks, such as those relating to foreign economic and political developments and foreign governmental restrictions. The profitability of the banking

industry is largely dependent upon the availability and cost of capital for the purpose of financing lending operations under prevailing money market conditions. Also, general economic conditions play an important part in the operation of the banking industry, and exposure to credit losses arising from possible financial difficulties of borrowers might affect a bank’s ability to meet its obligations under a letter of credit.

Other. Securities may be sold in anticipation of a market decline (a rise in interest rates) or purchased in anticipation of a market rise (a decline in interest rates). In addition, a security may be sold and another purchased at approximately the same time to take advantage of what the portfolio manager believes to be a temporary disparity in the normal yield relationship between the two securities. In general, the secondary market for tax-exempt securities in the Fund’s portfolio may have lower liquidity than that for taxable fixed income securities. Accordingly, the ability of the Fund to make purchases and sales of securities in the foregoing manner may be limited. Yield disparities may occur for reasons not directly related to the investment quality of particular issues or the general movement of interest rates, but instead due to such factors as changes in the overall demand for or supply of various types of tax-exempt securities or changes in the investment objectives of investors.

General Obligation Bonds. General obligation bonds are backed by the issuer’s pledge of its full faith, credit and taxing power for the payment of principal and interest. However, the taxing power of any governmental entity may be limited by provisions of state constitutions or laws and an entity’s credit will depend on many factors. Some such factors are the entity’s tax base, the extent to which the entity relies on federal or state aid, and other factors which are beyond the entity’s control.

Industrial Development Revenue Bonds (“IDRs”). IDRs are tax-exempt securities issued by states, municipalities, public authorities or similar entities to finance the cost of acquiring, constructing or improving various projects. These projects are usually operated by corporate entities. IDRs are not general obligations of governmental entities backed by their taxing power. Issuers are only obligated to pay amounts due on the IDRs to the extent that funds are available from the unexpended proceeds of the IDRs or receipts or revenues of the issuer. Payment of IDRs is solely dependent upon the creditworthiness of the corporate operator of the project or corporate guarantor. Such corporate operators or guarantors that are industrial companies may be affected by many factors, which may have an adverse impact on the credit quality of the particular company or industry.

Hospital and Health Care Facility Bonds. The ability of hospitals and other health care facilities to meet their obligations with respect to revenue bonds issued on their behalf is dependent on various factors. Some such factors are the level of payments received from private third-party payors and government programs and the cost of providing health care services, as well as competition from other health care facilities and providers. There can be no assurance that payments under governmental programs will be sufficient to cover the costs associated with their bonds. It also may be necessary for a hospital or other health care facility to incur substantial capital expenditures or increased operating expenses to effect changes in its facilities, equipment, personnel and services. Hospitals and other health care facilities are additionally subject to claims and legal actions by patients and others in the ordinary course of business. There can be no assurance that a claim will not exceed the insurance coverage of a health care facility or that insurance coverage will be available to a facility.

Single Family and Multi-Family Housing Bonds. Multi-family housing revenue bonds and single family mortgage revenue bonds are state and local housing issues that have been issued to provide financing for various housing projects. Multi-family housing revenue bonds are payable primarily from mortgage loans to housing projects for low to moderate income families. Single-family mortgage revenue bonds are issued for the purpose of acquiring notes secured by mortgages on residences. The ability of housing issuers to make debt service payments on their obligations may be affected by various economic and non-economic factors. Such factors include: occupancy levels, adequate rental income in multi-family projects, the rate of default on mortgage loans underlying single family issues and the ability of mortgage insurers to pay claims. All single-family mortgage revenue bonds and certain multi-family housing revenue bonds are prepayable over the life of the underlying mortgage or mortgage pool. Therefore, the average life of housing obligations cannot be determined. However, the average life of these obligations will ordinarily be less than their stated maturities. Mortgage loans are frequently partially or completely prepaid prior to their final stated maturities.

Power Facility Bonds. The ability of utilities to meet their obligations with respect to bonds they issue is dependent on various factors. These factors include the rates that they may charge their customers, the demand for a utility’s services and the cost of providing those services. Utilities are also subject to extensive regulations relating to the rates which they may charge customers. Utilities can experience regulatory, political and consumer resistance to rate increases. Utilities engaged in long-term

capital projects are especially sensitive to regulatory lags in granting rate increases. Utilities are additionally subject to increased costs due to governmental environmental regulation and decreased profits due to increasing competition. Any difficulty in obtaining timely and adequate rate increases could adversely affect a utility’s results of operations. The portfolio manager cannot predict with certainty the effect of such factors on the ability of issuers to meet their obligations with respect to bonds.

Water and Sewer Revenue Bonds. Water and sewer bonds are generally payable from user fees. The ability of state and local water and sewer authorities to meet their obligations may be affected by a number of factors. Some such factors are the failure of municipalities to utilize fully the facilities constructed by these authorities, declines in revenue from user charges, rising construction and maintenance costs, impact of environmental requirements, the difficulty of obtaining or discovering new supplies of fresh water, the effect of conservation programs, the impact of “no growth” zoning ordinances and the continued availability of federal and state financial assistance and of municipal bond insurance for future bond issues.

University and College Bonds. The ability of universities and colleges to meet their obligations is dependent upon various factors. Some of these factors of which an investor should be aware are the size and diversity of their sources of revenues, enrollment, reputation, management expertise, the availability and restrictions on the use of endowments and other funds and the quality and maintenance costs of campus facilities. Also, in the case of public institutions, the financial condition of the relevant state or other governmental entity and its policies with respect to education may affect an institution’s ability to make payments on its own.

Lease Rental Bonds. Lease rental bonds are predominantly issued by governmental authorities that have no taxing power or other means of directly raising revenues. Rather, the authorities are financing vehicles created solely for the construction of buildings or the purchase of equipment that will be used by a state or local government. Thus, the bonds are subject to the ability and willingness of the lessee government to meet its lease rental payments, which include debt service on the bonds. Lease rental bonds are subject to the risk that the lessee government is not legally obligated to budget and appropriate for the rental payments beyond the current fiscal year. These bonds are also subject to the risk of abatement in many states as rents cease in the event that damage, destruction or condemnation of the project prevents its use by the lessee. Also, in the event of default by the lessee government, there may be significant legal and/or practical difficulties involved in the reletting or sale of the project.

Capital Improvement Facility Bonds. Capital improvement bonds are bonds issued to provide funds to assist political subdivisions or agencies of a state through acquisition of the underlying debt of a state or local political subdivision or agency. The risks of an investment in such bonds include the risk of possible prepayment or failure of payment of proceeds on and default of the underlying debt.

Solid Waste Disposal Bonds. Bonds issued for solid waste disposal facilities are generally payable from tipping fees and from revenues that may be earned by the facility on the sale of electrical energy generated in the combustion of waste products. The ability of solid waste disposal facilities to meet their obligations depends upon the continued use of the facility, the successful and efficient operation of the facility and, in the case of waste-to-energy facilities, the continued ability of the facility to generate electricity on a commercial basis. Also, increasing environmental regulation on the federal, state and local level has a significant impact on waste disposal facilities. While regulation requires more waste producers to use waste disposal facilities, it also imposes significant costs on the facilities.

Moral Obligation Bonds. A moral obligation bond is a type of revenue bond issued by a state or municipality pursuant to legislation authorizing the establishment of a reserve fund to pay principal and interest payments if the issuer is unable to meet its obligations. The establishment of such a reserve fund generally requires appropriation by the state legislature, which is not legally required. Accordingly, the establishment of a reserve fund is generally considered a moral commitment but not a legal obligation of the state or municipality that created the issuer.

Pre-Refunded Bonds. Pre-refunded bonds are typically secured by direct obligations of the U.S. government, or in some cases obligations guaranteed by the U.S. government, placed in an escrow account maintained by an independent trustee until maturity or a predetermined redemption date. These obligations are generally non-callable prior to maturity or the predetermined redemption date. In a few isolated instances to date, however, bonds which were thought to be escrowed to maturity have been called for redemption prior to maturity. For credit ratings purposes, pre-refunded bonds are deemed to be unrated. The Subadviser determines the credit quality of pre-refunded bonds based on the quality of the escrowed collateral and such other factors as the Subadviser deems appropriate.

Airport, Port and Highway Revenue Bonds. Certain facility revenue bonds are payable from and secured by the revenue from the ownership and operation of particular facilities, such as airports, highways and port authorities. Airport operating income may be affected by the ability of airlines to meet their obligations under the agreements with airports. Similarly, payment on bonds related to other facilities is dependent on revenues from the projects, such as use fees from ports, tolls on turnpikes and bridges and rents from buildings. Therefore, payment may be adversely affected by reduction in revenues due to such factors and increased cost of maintenance or decreased use of a facility. The portfolio manager cannot predict what effect conditions may have on revenues which are required for payment on these bonds.

Special Tax Bonds. Special tax bonds are payable from and secured by the revenues derived by a municipality from a particular tax. Examples of such special taxes are a tax on the rental of a hotel room, the purchase of food and beverages, the rental of automobiles or the consumption of liquor. Special tax bonds are not secured by the general tax revenues of the municipality, and they do not represent general obligations of the municipality. Therefore, payment on special tax bonds may be adversely affected by a reduction in revenues realized from the underlying special tax. Also, should spending on the particular goods or services that are subject to the special tax decline, the municipality may be under no obligation to increase the rate of the special tax to ensure that sufficient revenues are raised from the shrinking taxable base.

Tax Allocation Bonds. Tax allocation bonds are typically secured by incremental tax revenues collected on property within the areas where redevelopment projects financed by bond proceeds are located. Such payments are expected to be made from projected increases in tax revenues derived from higher assessed values of property resulting from development in the particular project area and not from an increase in tax rates. Special risk considerations include: reduction of, or a less than anticipated increase in, taxable values of property in the project area; successful appeals by property owners of assessed valuations; substantial delinquencies in the payment of property taxes; or imposition of any constitutional or legislative property tax rate decrease.

Tobacco Settlement Revenue Bonds. Tobacco settlement revenue bonds are secured by a state or local government’s proportionate share in the Master Settlement Agreement (“MSA”). The MSA is an agreement, reached out of court in November 1998 between the attorneys general of 46 states (Florida, Minnesota, Mississippi and Texas all settled independently) and six other U.S. jurisdictions (including the District of Columbia, Puerto Rico and Guam), and the four largest U.S. tobacco manufacturers at that time (Philip Morris, RJ Reynolds, Brown & Williamson, and Lorillard). Subsequently, smaller tobacco manufacturers signed on to the MSA. The MSA basically provides for payments annually by the manufacturers to the states and jurisdictions in perpetuity, in exchange for releases of all claims against the manufacturers and a pledge of no further litigation. The MSA established a base payment schedule and a formula for adjusting payments each year. Manufacturers pay into a master escrow trust based on their market share, and each state receives a fixed percentage of the payment as set forth in the MSA. Annual payments are highly dependent on annual domestic cigarette shipments and inflation, as well as several other factors. As a result, payments made by tobacco manufacturers could be reduced if there is a decrease in tobacco consumption over time. A market share loss by the MSA companies to non-MSA participating manufacturers would also cause a downward adjustment in the payment amounts. A participating manufacturer filing for bankruptcy could cause delays or reductions in bond payments.

Certain tobacco settlement revenue bonds are issued with “turbo” redemption features. Under this turbo structure, all available excess revenues are applied as an early redemption to the designated first turbo maturity until it is completely repaid, and then to the next turbo maturity until paid in full, and so on. The result is that the returned principal creates an average maturity that could be much shorter than the legal final maturity.

Transit Authority Bonds. Mass transit is generally not self-supporting from fare revenues. Therefore, additional financial resources must be made available to ensure operation of mass transit systems as well as the timely payment of debt service. Often such financial resources include federal and state subsidies, lease rentals paid by funds of the state or local government or a pledge of a special tax. If fare revenues or the additional financial resources do not increase appropriately to pay for rising operating expenses, the ability of the issuer to adequately service the debt may be adversely affected.

Convention Facility Bonds. Bonds in the convention facilities category include special limited obligation securities issued to finance convention and sports facilities payable from rental payments and annual governmental appropriations. The governmental agency is not obligated to make payments in any year in which the monies have not been appropriated to make such payments. In addition, these facilities are limited use facilities that may not be used for purposes other than as convention centers or sports facilities.

Correctional Facility Bonds. Bonds in the correctional facilities category include special limited obligation securities issued to construct, rehabilitate and purchase correctional facilities payable from governmental rental payments and/or appropriations. An issuer’s ability to pay its lease obligations under these bonds could be adversely affected by a number of factors, including insufficient occupancy rates, unanticipated costs (such as legal claims), or the reduction or discontinuation of legislative appropriations.

Land-Secured or “Dirt” Bonds. Land-secured or “dirt” bonds are issued in connection with special taxing districts that are organized to plan and finance infrastructure development to induce residential, commercial and industrial growth and redevelopment. Obligations under these bonds are generally payable solely from taxes (using methods such as tax assessments, special taxes or tax increment financing) or other revenues attributable to the specific projects financed by the bonds, without recourse to the credit or taxing power of related or overlapping municipalities. The projects to which these bonds relate often are exposed to real estate development-related risks, such as the failure of property development, unavailability of financing, extended vacancies of properties, increased competition, limitations on rents, changes in neighborhood values, lessening demand for properties, and changes in interest rates. These real estate risks may be heightened if a project is subject to foreclosure and, in that event, the Fund, as a holder of the bonds, might be required to pay certain maintenance or operating expenses or taxes relating to the project. In addition, the bonds financing these projects may have more taxpayer concentration risk than general tax-supported bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings generally are limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if a development fails to progress as anticipated or if taxpayers fail to pay the assessments, fees and taxes as provided in the financing plans of the projects.

Municipal securities include the obligations of the governments of Puerto Rico and other U.S. territories and their political subdivisions (such as the U.S. Virgin Islands and Guam). Payment of interest and preservation of principal is dependent upon the continuing ability of such issuers and/or obligors of territorial, municipal and public authority debt obligations to meet their obligations thereunder. The sources of payment for such obligations and the marketability thereof may be affected by financial and other difficulties experienced by such issuers.

Puerto Rico. Municipal securities of issuers located in the Commonwealth of Puerto Rico may be affected by political, social and economic conditions in Puerto Rico. Puerto Rico’s economy has been in a recession since late 2006, which has contributed to a steep increase in unemployment rates, funding shortfalls of state employees’ retirement systems, a budget deficit resulting from a structural imbalance, and reduced government revenues. In May 2017, Puerto Rico made a filing in the U.S. District Court in Puerto Rico to commence a debt restructuring process similar to that of a traditional municipal bankruptcy. Puerto Rico had previously defaulted on certain agency debt payments and the Governor had warned of its inability to meet additional pending obligations, including under general obligation bonds.

The debt restructuring process commenced by Puerto Rico is under a federal law for insolvent U.S. territories, called Promesa. Puerto Rico’s case is the first ever heard under Promesa for which there is no existing body of court precedent. Accordingly, Puerto Rico’s debt restructuring process could take significantly longer than recent municipal bankruptcy proceedings adjudicated pursuant to Chapter 9 of the U.S. Bankruptcy Code.

It is not clear whether a debt restructuring process will ultimately be approved or, if so, the extent to which it will apply to Puerto Rico municipal securities sold by an issuer other than the Commonwealth. A debt restructuring could reduce the principal amount due, the interest rate, the maturity and other terms of Puerto Rico municipal securities. These changes, as well as the delay imposed by the debt restructuring process itself, could adversely affect the value of Puerto Rico municipal securities. The court filing made by Puerto Rico could also have a negative impact on the value of Puerto Rico municipal securities that are not subject to the debt restructuring process. In addition, Puerto Rico municipal securities remain subject to all of the other risks applicable to fixed income securities, including the risk of non-payment. To the extent that the Fund holds any Puerto Rico municipal securities, the Fund may lose some or all of the value of those investments.

These challenges and uncertainties have been exacerbated by Hurricane Maria, which directly hit Puerto Rico on September 20, 2017, causing significant damage to the island’s infrastructure (including water, power and telecommunications) and to governmental, personal and business property. Moody’s Analytics has estimated that the island suffered tens of billions of

dollars in hurricane-related damages. It is unknown what impact this disaster will have on the ongoing efforts to restructure Puerto Rico’s debt.

The following is a brief summary of certain factors affecting Puerto Rico’s economy and does not purport to be a complete description of such factors.

The dominant sectors of the Puerto Rico economy are manufacturing and services. The manufacturing sector has undergone fundamental changes over the years as a result of increased emphasis on higher wage, high technology industries, such as pharmaceuticals, biotechnology, computers, microprocessors, professional and scientific instruments, and certain high technology machinery and equipment. The services sector, including finance, insurance, real estate, wholesale and retail trade, transportation, communications and public utilities and other services, also plays a major role in the economy. It ranks second only to manufacturing in contribution to the gross domestic product and leads all sectors in providing employment.

Most external factors that affect the Puerto Rico economy are determined by the policies and performance of the United States. These external factors include exports, direct investment, the amount of federal transfer payments, the level of interest rates, the rate of inflation, and tourist expenditures.

Guam. General obligations and/or revenue bonds of issuers located in Guam may be affected by political, social and economic conditions in Guam. The following is a brief summary of factors affecting the economy of Guam and does not purport to be a complete description of such factors.

Guam, the westernmost territory of the U.S., is located 3,800 miles to the west-southwest of Honolulu, Hawaii and approximately 1,550 miles south-southeast of Tokyo, Japan. The population of Guam was estimated to be 167,402 in July 2019. Guam’s unemployment rate increased from 9.3% in September 2009 to 13.3% in March 2013, and decreased to 4.4% in January 2018.

Guam’s economy depends in large measure on tourism and the U.S. military presence, each of which is subject to uncertainties as a result of global economic, social and political events. Tourism, particularly from Japan, which has been a source of a majority of visitors to Guam, represents the primary source of income for Guam’s economy. A weak economy, war, severe weather, epidemic outbreaks or the threat of terrorist activity, among other influences that are beyond Guam’s control, can adversely affect its tourism industry. Guam is also exposed to periodic typhoons, tropical storms, super typhoons and earthquakes, such as the March 2011 earthquake and tsunami that occurred in Japan and caused a decline in tourism for a period of time. The U.S. military presence also affects economic activity on Guam in various ways. The number of U.S. military personnel in Guam declined in 2011. Economic, geopolitical, and other influences which are beyond Guam’s control could cause the U.S. military to reduce its existing presence on Guam or forgo any planned enhancements to its presence on Guam. Any reduction in tourism or the U.S. military presence could adversely affect Guam’s economy.

United States Virgin Islands. General obligations and/or revenue bonds of issuers located in the U.S. Virgin Islands may be affected by political, social and economic conditions in the U.S. Virgin Islands. The territory has experienced high levels of debt, increasing pension obligations and a declining population. The credit rating of certain bonds issued by the territory have been downgraded due to a perceived increased possibility that the territory may be forced to restructure its debts to address its financial problems.

In September 2017, the territory was hit by two hurricanes within the span of two weeks. Together, the hurricanes caused significant damage to the most populated islands, including to their infrastructure, hospitals, homes and other structures.

The following is a brief summary of factors affecting the economy of the U.S. Virgin Islands and does not purport to be a complete description of such factors.

The U.S. Virgin Islands consists of four main islands: St. Croix, St. Thomas, St. John, and Water Island and approximately 70 smaller islands, islets and cays. The total land area is about twice the size of Washington, D.C.

The U.S. Virgin Islands is located 60 miles east of Puerto Rico and 1,075 miles south of Miami, Florida in the Caribbean Sea and the Atlantic Ocean. The population of the U.S. Virgin Islands was estimated to be 104,909 in July 2019.

Tourism, trade, and other services, including manufacturing (rum distilling, watch assembly, pharmaceuticals, and electronics), are the primary economic activities, accounting for a substantial portion of the Virgin Island’s gross domestic product and civilian employment. The agricultural sector is small, with most of the islands’ food being imported. A weak

economy, severe weather, war, epidemic outbreaks or the threat of terrorist activity, among other influences that are beyond the control of the territory, can adversely affect its tourism and other industries.

Repurchase Agreements (Except for Premier Institutional U.S. Treasury Reserves)

Under the terms of a typical repurchase agreement, the Fund would acquire one or more underlying debt securities from a counterparty (typically a bank or a broker-dealer), subject to the counterparty’s obligation to repurchase, and the Fund to resell, the securities at an agreed-upon time and price. The Fund may enter into repurchase agreements where the underlying collateral consists entirely of cash items and/or securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises. The Fund may also enter into repurchase agreements where the underlying collateral consists of other types of securities, including securities the Fund could not purchase directly. For such repurchase agreements, the underlying securities which serve as collateral may include, but are not limited to, U.S. government securities, municipal securities, corporate debt obligations, asset-backed securities (including collateralized mortgage obligations (“CMOs”)), convertible securities and common and preferred stock and may be of below investment grade quality. The repurchase price is typically greater than the purchase price paid by the Fund, thereby determining the Fund’s yield. A repurchase agreement is similar to, and may be treated as, a secured loan, where the Fund loans cash to the counterparty and the loan is secured by the underlying securities as collateral. All repurchase agreements entered into by the Fund are required to be collateralized so that at all times during the term of a repurchase agreement, the value of the underlying securities is at least equal to the amount of the repurchase price. Also, the Fund or its custodian is required to have control of the collateral, which the portfolio manager believes will give the Fund a valid, perfected security interest in the collateral.

Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty, including possible delays or restrictions upon the Fund’s ability to dispose of the underlying securities, the risk of a possible decline in the value of the underlying securities during the period in which the Fund seeks to assert its right to them, the risk that there may be a limited market or no market for disposition of such underlying securities, the risk of incurring expenses associated with asserting those rights and the risk of losing all or part of the income from the agreement. The Fund will seek to mitigate these risks but there is no guarantee that such efforts will be successful. If the Fund enters into a repurchase agreement involving securities the Fund could not purchase directly, and the counterparty defaults, the Fund may become the holder of such securities. Repurchase agreements collateralized by securities other than U.S. government securities may be subject to greater risks and are more likely to have a term to maturity of longer than seven days. Repurchase agreements with a maturity of more than seven days are considered to be illiquid.

Repurchase agreements may be entered into or novated with a financial clearinghouse, which would become the Fund’s counterparty. The Fund would then become subject to the rules of the clearinghouse, which may limit the Fund’s rights and remedies (including recourse to collateral) or delay or restrict the rights and remedies, and expose the Fund to the risks of the clearinghouses’ insolvency.

Pursuant to an exemptive order issued by the SEC, the Fund, along with other affiliated entities managed by the Manager, may transfer uninvested cash balances into one or more joint accounts for the purpose of entering into repurchase agreements secured by cash and U.S. government securities, subject to certain conditions.

Reverse Repurchase Agreements (Except for Premier Institutional U.S. Treasury Reserves)

The Fund may enter into reverse repurchase agreements. A reverse repurchase agreement has the characteristics of a secured borrowing by the Fund and creates leverage in the Fund’s portfolio. In a reverse repurchase transaction, the Fund sells a portfolio instrument to another person, such as a financial institution or broker-dealer, in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed-upon time and at a price that is greater than the amount of cash that the Fund received when it sold the instrument, representing the equivalent of an interest payment by the Fund for the use of the cash. During the term of the transaction, the Fund will continue to receive any principal and interest payments (or the equivalent thereof) on the underlying instruments.

The Fund may engage in reverse repurchase agreements as a means of raising cash to satisfy redemption requests or for other temporary or emergency purposes. Unless otherwise limited in the Fund’s Prospectus or this SAI, the Fund may also engage in reverse repurchase agreements to the extent permitted by its fundamental investment policies in order to raise additional cash to be invested by the Fund’s portfolio manager in other securities or instruments in an effort to increase the Fund’s investment returns.

During the term of the transaction, the Fund will remain at risk for any fluctuations in the market value of the instruments subject to the reverse repurchase agreement as if it had not entered into the transaction. When the Fund reinvests the proceeds of a reverse repurchase agreement in other securities, the Fund will also be at risk for any fluctuations in the market value of the securities in which the proceeds are invested. Like other forms of leverage, this makes the value of an investment in the Fund more volatile and increases the Fund’s overall investment exposure. In addition, if the Fund’s return on its investment of the proceeds of the reverse repurchase agreement does not equal or exceed the implied interest that it is obligated to pay under the reverse repurchase agreement, engaging in the transaction will lower the Fund’s return.

When the Fund enters into a reverse repurchase agreement, it is subject to the risk that the buyer under the agreement may file for bankruptcy, become insolvent or otherwise default on its obligations to the Fund. In the event of a default by the counterparty, there may be delays, costs and risks of loss involved in the Fund’s exercising its rights under the agreement, or those rights may be limited by other contractual agreements or obligations or by applicable law.

In addition, the Fund may be unable to sell the instruments subject to the reverse repurchase agreement at a time when it would be advantageous to do so, or may be required to liquidate portfolio securities at a time when it would be disadvantageous to do so in order to make payments with respect to its obligations under a reverse repurchase agreement. This could adversely affect the Fund’s strategy and result in lower fund returns. At the time the Fund enters into a reverse repurchase agreement, the Fund is required to set aside cash or other appropriate liquid securities in the amount of the Fund’s obligation under the reverse repurchase agreement or take certain other actions in accordance with SEC guidelines, which may affect the Fund’s liquidity and ability to manage its assets. Although complying with SEC guidelines would have the effect of limiting the amount of fund assets that may be committed to reverse repurchase agreements and other similar transactions at any time, it does not otherwise mitigate the risks of entering into reverse repurchase agreements.

The Fund will not engage in reverse repurchase agreements if its total borrowings exceed 33-1/3% of its total assets.

Issuers of obligations may employ various forms of credit and liquidity enhancements, including letters of credit, guarantees, swaps, puts and demand features, and insurance, provided by U.S. or non-U.S. entities such as banks and other financial institutions. Changes in the credit quality of the entities providing the enhancement could affect the value of the securities or the Fund’s share price. U.S. banks and certain financial institutions are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments which may be made and interest rates and fees which may be charged. Non-U.S. banks and financial institutions may be less regulated than their U.S. counterparts and may be subject to additional risks, such as those relating to foreign economic and political developments and foreign governmental restrictions. The profitability of the banking industry is largely dependent upon the availability and cost of capital for the purpose of financing lending operations under prevailing money market conditions. Also, general economic conditions play an important part in the operation of the banking industry, and exposure to credit losses arising from possible financial difficulties of borrowers might affect a bank’s ability to meet its obligations under a letter of credit.

Securities Lending (Except for Premier Institutional U.S. Treasury Reserves)

The Fund may lend its portfolio securities, provided that cash or equivalent collateral, equal to at least 100% of the market value of such securities, is continuously maintained by the other party with the Fund. During the pendency of the transaction, the other party will pay the Fund an amount equivalent to any dividends or interest paid on such securities, and the Fund may invest the cash collateral and earn additional income, or it may receive an agreed upon amount of interest income from the other party who has delivered equivalent collateral. These transactions are subject to termination at the option of the Fund or the other party. The Fund may pay administrative and custodial fees in connection with these transactions and may pay a negotiated portion of the interest earned on the cash or equivalent collateral to the other party or placing agent or broker. Although voting rights or rights to consent with respect to the relevant securities generally pass to the other party, the Fund will make arrangements to vote or consent with respect to a material event affecting such securities. SEC guidance currently states that a fund may loan securities equal in value to no more than one third of its total asset value, including collateral received in connection with such transactions (at market value computed at the time of the transaction). The risks in lending portfolio securities include possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. The Fund runs the risk that the counterparty to a loan transaction will default on its obligation and that the value of the collateral received may decline before the Fund can dispose of it. If the Fund receives cash as collateral and invests that

cash, the Fund is subject to the risk that the collateral will decline in value before the Fund must return it to the counterparty. Subject to the foregoing, loans of fund securities are effectively borrowings by the Fund and have economic characteristics similar to reverse repurchase agreements. The Fund does not currently intend to engage in securities lending, although it may engage in transactions (such as reverse repurchase agreements) which have similar characteristics.

Structured instruments are money market instruments that have been structured to meet the regulatory requirements for investment by money market funds, typically by a bank, broker/dealer or other financial institution. They generally consist of a trust or partnership through which the Fund holds an interest in one or more underlying bonds or other debt obligations coupled with a conditional right to sell (“put”) the Fund’s interest in the underlying bonds at par plus accrued interest to a financial institution. With respect to tax-exempt instruments, the instrument is typically structured as a trust or partnership which provides for pass-through tax-exempt income. Structured instruments in which the Fund may invest include: (1) tender option bonds, (2) swap products, in which the trust or partnership swaps the payments due on an underlying bond with a swap counterparty who agrees to pay a floating money market interest rate; and (3) partnerships, which allocate to the partners income, expenses, capital gains and losses in accordance with a governing partnership agreement. Structured instruments may be more volatile, have lower liquidity and may be more difficult to price accurately than less complex securities or more traditional debt securities.

These types of instruments raise certain tax, legal, regulatory and accounting issues which may not be presented by direct investments in debt obligations. There is some risk that certain of these issues could be resolved in a manner that could adversely impact the performance of the Fund.

The Fund may depart from its principal investment strategies in response to adverse market, economic or political conditions by taking temporary defensive positions, including by investing in any type of investment grade, government, corporate and money market instruments and short-term debt securities or holding cash without regard to any percentage limitations. Although the portfolio manager has the ability to take defensive positions, they may choose not to do so for a variety of reasons, even during volatile market conditions.

U.S. Government securities include (1) U.S. Treasury bills (maturity of one year or less), U.S. Treasury notes (maturity of one to ten years) and U.S. Treasury bonds (maturities generally greater than ten years); (2) obligations issued or guaranteed by U.S. Government agencies or instrumentalities which are supported by any of the following: (a) the full faith and credit of the U.S. Government (such as certificates issued by the Government National Mortgage Association (“Ginnie Mae”)); (b) the right of the issuer to borrow an amount limited to a specific line of credit from the U.S. Government (such as obligations of the Federal Home Loan Banks); (c) the discretionary authority of the U.S. Government to purchase certain obligations of agencies or instrumentalities (such as securities issued by the Federal National Mortgage Association); or (d) only the credit of the agency or instrumentality (such as securities issued by the Federal Home Loan Mortgage Corporation); and (3) obligations issued by non-governmental entities (like financial institutions) that carry direct guarantees from U.S. government agencies as part of government initiatives in response to a market crisis or otherwise. Agencies and instrumentalities of the U.S. Government include but are not limited to: Farmers Home Administration, Export-Import Bank of the United States, Federal Housing Administration, Federal Land Banks, Federal Financing Bank, Central Bank for Cooperatives, Federal Intermediate Credit Banks, Farm Credit Bank System, Federal Home Loan Banks, Federal Home Loan Mortgage Corporation, Federal National Mortgage Association, General Services Administration, Government National Mortgage Association, Student Loan Marketing Association, United States Postal Service, Maritime Administration, Small Business Administration, Tennessee Valley Authority, Washington D.C. Armory Board and any other instrumentality established or sponsored by the U.S. Government.

In the case of obligations not backed by the full faith and credit of the United States, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment and may not be able to assert a claim against the United States itself in the event the agency or instrumentality does not meet its commitments. Neither the U.S. Government nor any of its agencies or instrumentalities guarantees the market value of the securities they issue. Therefore, the market value of such securities will fluctuate in response to changes in interest rates and other factors. In addition, any

downgrade of the credit rating of the securities issued by the U.S. Government may result in a downgrade of securities issued by its agencies or instrumentalities, including government-sponsored entities.

U.S. Treasury obligations are direct debt obligations issued by the U.S. government. Treasury bills, with maturities normally from 4 weeks to 52 weeks, are typically issued at a discount as they pay interest only upon maturity. Treasury bills are non-callable. Treasury notes have a maturity between two and ten years and typically pay interest semi-annually, while Treasury bonds have a maturity of over ten years and pay interest semi- annually. U.S. Treasury obligations also include STRIPS, TIPS, and FRNs. STRIPS are Treasury obligations with separately traded principal and interest component parts of such obligations that are transferable through the federal book-entry system. The principal and interest components of U.S. Treasury bonds with remaining maturities of longer than ten years are eligible to be traded independently under the STRIPS program. Under the STRIPS program, the principal and interest components are separately issued through depository financial institutions, which then trade the component parts separately. Each interest payment and the principal payment becomes a separate zero-coupon security. STRIPS pay interest only at maturity. The interest component of STRIPS may be more volatile than that of U.S. Treasury bills with comparable maturities. TIPS are Treasury Inflation-Protected Securities, the principal of which increases with inflation and decreases with deflation. The inflation adjustment is based on a two month-lagged value of the non-seasonally adjusted Consumer Price Index for Urban Consumers (CPI-U). TIPS entitle the holder, upon maturity, to the adjusted principal or original principal, whichever is greater, thus providing a deflation floor. TIPS pay interest twice a year, at a fixed rate. The rate is applied to the adjusted principal; so, like the principal, interest payments rise with inflation and fall with deflation. However, because the interest rate is fixed, TIPS may lose value when market interest rates increase, particularly during periods of low inflation. FRNs are floating rate notes, the interest on which is indexed to the most recent 13-week Treasury bill auction High Rate, which is the highest accepted discount rate in a Treasury bill auction.

Variable and floating rate securities provide for a periodic adjustment in the interest rate paid on the obligations. The terms of such obligations provide that interest rates are adjusted periodically based upon an interest rate adjustment index as provided in the respective obligations. The adjustment intervals may be regular, and range from daily up to annually, or may be event-based, such as based on a change in the prime rate.

The Fund may invest in floating rate debt instruments (“floaters”) and engage in credit spread trades. The interest rate on a floater is a variable rate which is tied to another interest rate, such as a corporate bond index or U.S. Treasury bill rate. The interest rate on a floater resets periodically, typically every six months. While, because of the interest rate reset feature, floaters may provide the Fund with a certain degree of protection against rising interest rates, the Fund will participate in any declines in interest rates as well. A credit spread trade is an investment position relating to a difference in the prices or interest rates of two bonds or other securities or currencies, where the value of the investment position is determined by movements in the difference between the prices or interest rates, as the case may be, of the respective securities or currencies.

The Fund may also invest in variable amount master demand notes, which permit the indebtedness thereunder to vary in addition to providing for periodic adjustments in the interest rate. The absence of an active secondary market with respect to particular variable and floating rate instruments could make it difficult for the Fund to dispose of a variable or floating rate note if the issuer were to default on its payment obligation or during periods that the Fund is not entitled to exercise its demand rights, and the Fund could, for these or other reasons, suffer a loss with respect to such instruments. In determining average-weighted portfolio maturity, an instrument will be deemed to have a maturity equal to either the period remaining until the next interest rate adjustment or the time the Fund can recover payment of principal as specified in the instrument, depending on the type of instrument involved.

When-Issued Securities and Forward Commitments (Except for Premier Institutional U.S. Treasury Reserves)

The Fund may purchase securities on a “when-issued” or “to be announced” or “forward delivery” basis. The payment obligation and the interest rate that will be received on the “when-issued” securities are fixed at the time the buyer enters into the commitment although settlement, i.e., delivery of and payment for the securities, takes place at a later date. In a “to be announced” transaction, the Fund commits to purchase securities for which all specific information is not known at the time of the trade.

Securities purchased on a “when-issued” or “forward delivery” basis are subject to changes in value based upon the market’s perception of the creditworthiness of the issuer and changes, real or anticipated, in the level of interest rates. The value of these securities experiences appreciation when interest rates decline and depreciation when interest rates rise. Purchasing securities on a “when-issued” or “forward delivery” basis can involve a risk that the yields available in the market on the settlement date may actually be higher or lower than those obtained in the transaction itself. At the time the Fund enters into a “when-issued” or “forward delivery” commitment, the Fund will set aside cash or other appropriate liquid securities with a value at least equal to the Fund’s obligation under the commitment. The Fund’s liquidity and ability to manage its assets might be affected when it sets aside cash or portfolio securities to cover such commitments.

An increase in the percentage of the Fund’s assets committed to the purchase of securities on a “when-issued” basis may increase the volatility of its net asset value.

The business and affairs of the Fund are conducted by management under the supervision and subject to the direction of its Board. The business address of each Trustee (including each Independent Trustee) is c/o Jane Trust, Legg Mason, 100 International Drive, 11^th Floor, Baltimore, Maryland 21202. The tables below provide information about each of the Trustees and officers of the Trust.

Currently the Fund and other mutual funds within the Legg Mason Funds complex that are advised by Western Asset are overseen by two different boards. These boards, including the Board, approved a proposal recommending that shareholders elect a single group of board members, comprised principally of members of the two existing boards.

A proxy statement with respect to the election was filed with the SEC and was mailed to shareholders of record of other funds in the Legg Mason Funds complex in October 2019. A meeting of the shareholders of those funds will be held on or about December 3, 2019 to vote on the election of the proposed board members. If elected by shareholders, the new board members will assume their responsibilities, including with respect to the Fund, on January 1, 2020.

Qualifications of Trustees, Board Leadership Structure and Oversight and Standing Committees

The Independent Trustees were selected to join the Board based upon the following as to each Board Member: his or her contribution as a board member of predecessor funds; such person’s character and integrity; such person’s willingness to serve and willingness and ability to commit the time necessary to perform the duties of a Trustee; the fact that such person’s service would be consistent with the requirements of the retirement policies of the Trust; and his or her status as not being an “interested person” as defined in the 1940 Act. Ms. Trust was selected to join the Board based upon the following: her character and integrity; her willingness to serve and her willingness and ability to commit the time necessary to perform the duties of a Trustee; the fact that her service as a Trustee would be consistent with requirements of the Trust’s retirement policies, and her status as a representative of Legg Mason.

The Board believes that each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees lead to the conclusion that the Board possesses the requisite skills and attributes. The Board believes that the Trustees’ ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Manager, Subadviser, other service providers, counsel and independent auditors, and to exercise effective business judgment in the performance of their duties, support this conclusion. The Board has also considered the contributions that each Trustee can make to the Board and the Fund, as well as the perspectives gained from the Independent Trustees’ service on the board of the applicable predecessor funds. In addition, the following specific experience, qualifications, attributes and/ or skills apply as to each Trustee: Mr. Berv, experience as a chief executive officer and board member of various businesses and organizations and organizational consulting experience; Ms. Dasher, experience as a chief financial officer of a private investment company; Mr. Finn, investment management experience as an executive, consultant and portfolio manager; Mr. Gross, accounting background and experience as an officer and board member of various organizations; Ms. Heilbron, legal background and experience, business and consulting experience and experience as a board member of public companies; Ms. Kerley, investment consulting experience and background and mutual fund board experience; Dr. Pettit, economic and finance background and academic management experience; and Ms. Trust, investment management and risk oversight experience as an executive and portfolio manager and leadership roles within Legg Mason and affiliated entities. References to the qualifications, attributes and skills of Trustees are pursuant to requirements of the SEC, do not constitute holding out of the Board or any Trustee as having any special expertise or experience, and shall not impose any greater responsibility or liability on any such person or on the Board by reason thereof.

The Board is responsible for overseeing the management and operations of the Fund. Ms. Trust is an interested person of the Fund. Independent Trustees constitute more than 75% of the Board. Ms. Heilbron serves as Chair of the Board.

The Board has three standing committees: the Audit Committee, Nominating and Governance Committee (referred to as the Governance Committee), and Investment and Performance Committee (referred to as the Performance Committee). Each of the Audit, Governance and Performance Committees is chaired by an Independent Trustee and composed of all of the Independent Trustees. Where deemed appropriate, the Board constitutes ad hoc committees.

The Chair of the Board and the chairs of the Audit, Governance and Performance Committees work with the Chief Executive Officer of the Trust to set the agendas for Board and committee meetings. The Chair of the Board also serves as a key point person for dealings between management and the other Independent Trustees. As noted below, through the committees the Independent Trustees consider and address important matters involving the Fund, including those presenting conflicts or potential conflicts of interest for management. The Independent Trustees also regularly meet outside the presence of management and are advised by independent legal counsel. The Board has determined that its committees help ensure that the

Fund has effective and independent governance and oversight. The Board also has determined that its leadership structure, in which the Chair of the Board is not affiliated with Legg Mason, is appropriate. The Board also believes that its leadership structure facilitates the orderly and efficient flow of information to the Independent Trustees from management, including the Subadviser.

The Audit Committee oversees, among other things, the scope of the Fund’s audit, the Fund’s accounting and financial reporting policies and practices and the internal controls over financial accounting and reporting. The primary purposes of the Board’s Audit Committee are to assist the Board in fulfilling its responsibility for oversight of the integrity of the accounting, auditing and financial reporting practices of the Fund, and the qualifications and independence of the Fund’s independent registered public accounting firm. The Audit Committee approves, and recommends to the Independent Trustees for their ratification, the selection, appointment, retention or termination of the Fund’s independent registered public accounting firm and approves the compensation of the independent registered public accounting firm. The Audit Committee also approves all audit and permissible non-audit services provided to the Fund by the independent registered public accounting firm and all permissible non-audit services provided by the Fund’s independent registered public accounting firm to its manager and any affiliated service providers if the engagement relates directly to the Fund’s operations and financial reporting.

The Governance Committee is the forum for consideration of a number of issues required to be considered separately by independent trustees of mutual funds, including, among other things, recommending candidates to fill vacancies on the Board. The Governance Committee also considers issues that the Independent Trustees believe it is advisable for them to consider separately. When addressing vacancies, the Governance Committee may consider nominees recommended by a shareholder. Shareholders who wish to recommend a nominee should send recommendations to the Trust’s Secretary that include all information relating to such person that is required to be disclosed in solicitations of proxies for the election of Trustees. A recommendation must be accompanied by a written consent of the individual to stand for election if nominated by the Board and to serve if elected by the shareholders.

The Governance Committee also identifies potential nominees through its network of contacts and may also engage, if it deems appropriate, a professional search firm. The committee meets to discuss and consider such candidates’ qualifications and then chooses a candidate by majority vote. The committee does not have specific, minimum qualifications for nominees, nor has it established specific qualities or skills that it regards as necessary for one or more of the Trustees to possess (other than any qualities or skills that may be required by applicable law, regulation or listing standard). However, in evaluating a person as a potential nominee to serve as a Trustee, the Governance Committee may consider the following factors, among any others it may deem relevant:

The Performance Committee is charged with, among other things, reviewing investment performance. The Performance Committee also assists the Board in fulfilling its responsibility for the review and negotiation of the Fund’s investment management and subadvisory arrangements.

As an integral part of its responsibility for oversight of the Fund in the interests of shareholders, the Board oversees risk management of the Fund’s investment programs and business affairs. The Board has emphasized to the Fund’s Manager and Subadviser the importance of maintaining vigorous risk management. The Manager and the Subadviser also have their own independent interest in risk management and in maintaining risk management programs. Oversight of the risk management process is part of the Board’s general oversight of the Fund and its service providers. The Board exercises oversight of the risk management process primarily through the Performance Committee and the Audit Committee, and through oversight by the Board itself.

The Fund faces a number of risks, such as investment risk, counterparty risk, valuation risk, reputational risk, risk of operational failure or lack of business continuity, and legal, compliance and regulatory risk. Risk management seeks to identify and address risks, i.e., events or circumstances that could have material adverse effects on the business, operations, shareholder services, investment performance or reputation of the Fund. Under the overall oversight of the Board or the applicable committee, the Fund, or the Manager, the Fund’s Subadviser, and the affiliates of the Manager and the Subadviser, or other service providers to the Fund employ a variety of processes, procedures and controls to identify various of those possible events or circumstances, to lessen the probability of their occurrence and/or to mitigate the effects of such events or circumstances if they do occur.

Different processes, procedures and controls are employed with respect to different types of risks. Various personnel, including the Fund’s and the Manager’s CCO and the Manager’s chief risk officer, as well as various personnel of the Subadviser and other service providers such as the Fund’s independent accountants, also make periodic reports to the Performance Committee or Audit Committee or to the Board, pursuant to the committee’s or Board’s request, with respect to various aspects of risk management, as well as events and circumstances that have arisen and responses thereto.

The Board recognizes that not all risks that may affect the Fund can be identified, that it may not be practical or cost-effective to eliminate or mitigate certain risks, that it may be necessary to bear certain risks (such as investment-related risks) to achieve the Fund’s goals, and that the processes, procedures and controls employed to address certain risks may be limited in their effectiveness. Moreover, reports received by the Trustees as to risk management matters are typically summaries of the relevant information. As a result of the foregoing and other factors, the Board’s risk management oversight is subject to substantial limitations.

The Portfolio is also governed by a board, which has the same members and committees as the Fund’s Board.

During the fiscal year ended August 31, 2019, the Board met 4 times, the Audit Committee met 4 times, the Nominating and Governance Committee met 4 times, and the Investment and Performance Committee met 4 times.

The following tables show the dollar range of equity securities owned by the Trustees in the Fund and other investment companies in the Legg Mason Funds complex overseen by the Trustees as of December 31, 2018.

As of December 31, 2018, none of the Independent Trustees or their immediate family members owned beneficially or of record any securities of the Manager, the Subadviser, or the Distributor of the Fund, or of a person (other than a registered investment company) directly or indirectly controlling, controlled by or under common control with the Manager, the Subadviser, or the Distributor of the Fund.

For serving as a Trustee of the Trust, each Independent Trustee receives an annual retainer plus fees for attending each regularly scheduled meeting and special Board meeting they attend in person or by telephone. Each Independent Trustee is also reimbursed for all out-of-pocket expenses relating to attendance at such meetings. Those Independent Trustees who serve in leadership positions of the Board or Board committees receive additional compensation. The Board reviews the level of Trustee compensation periodically and Trustee compensation may change from time to time. Ms. Trust, an “interested person” of the Fund, as defined in the 1940 Act, does not receive compensation from the Fund for her service as Trustee. The Fund pays its pro rata share of the fees and expenses of the Trustees based upon asset size.

Officers of the Trust receive no compensation from the Fund, although they may be reimbursed for reasonable out-of-pocket travel expenses for attending Board meetings.

The Manager, a limited liability company organized under the laws of the State of Delaware, serves as investment manager to the Fund and the Portfolio and provides administrative and certain oversight services to the Fund and the Portfolio, pursuant to an investment management agreement (the “Management Agreement”). The Manager has offices at 620 Eighth Avenue, New York, New York, 10018 and also serves as the investment manager of other Legg Mason Funds. The Manager is a wholly-owned subsidiary of Legg Mason, a Maryland corporation. Legg Mason, whose principal executive offices are at 100 International Drive, Baltimore, Maryland 21202, is a global asset management company. References to the Fund in the following paragraphs include the Portfolio, if applicable.

The Manager has agreed, under the Management Agreement, subject to the supervision of the Board, to provide the Fund and the Portfolio with investment research, advice, management and supervision, furnish a continuous investment program for the Fund’s or the Portfolio’s portfolio of securities and other investments consistent with the Fund’s or the Portfolio’s investment objectives, policies and restrictions, and place orders pursuant to its investment determinations. The Manager is permitted to enter into contracts with subadvisers or subadministrators, subject to the Board’s approval. The Manager has entered into subadvisory agreements, as described below.

As compensation for services performed, facilities furnished and expenses assumed by the Manager, the Fund pays the Manager a fee computed daily at an annual rate of the Fund’s average daily net assets as described below. The Manager also performs administrative and management services as reasonably requested by the Fund necessary for the operation of the Fund, such as (i) supervising the overall administration of the Fund, including negotiation of contracts and fees with, and monitoring of performance and billings of, the Fund’s transfer agent, shareholder servicing agents, custodian and other independent contractors or agents; (ii) providing certain compliance, fund accounting, regulatory reporting and tax reporting services; (iii) preparing or participating in the preparation of Board materials, registration statements, proxy statements and reports and other communications to shareholders; (iv) maintaining the Fund’s existence; and (v) maintaining the registration or qualification of the Fund’s shares under federal and state laws.

The Management Agreement will continue in effect from year to year, provided continuance is specifically approved at least annually (a) by the Board or by a 1940 Act Vote, and (b) in either event, by a majority of the Independent Trustees, with such Independent Trustees casting votes in person at a meeting called for such purpose.

The Management Agreement provides that the Manager may render services to others. The Management Agreement is terminable without penalty by the Board or by vote of a majority of the outstanding voting securities of the Fund on not more than 60 days’ nor less than 30 days’ written notice to the Manager, or by the Manager on not less than 90 days’ written notice to the Fund as applicable, and will automatically terminate in the event of its assignment (as defined in the 1940 Act) by the Manager. No Management Agreement is assignable by the Trust except with the consent of the Manager.

The Management Agreement provides that the Manager, its affiliates performing services contemplated by the Management Agreement, and the partners, shareholders, directors, officers and employees of the Manager and such affiliates, will not be liable for any error of judgment or mistake of law, for any loss arising out of any investment, or for any act or omission in the execution of securities transactions for the Fund, but the Manager is not protected against any liability to the Fund to which the Manager would be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the Management Agreement.

Subject to such policies as the Board or the board of the Portfolio, as applicable, may determine, the Manager manages the securities of and makes investment decisions for the Portfolio. Currently, advisory services for the Fund are provided through the Portfolio, but the Manager may, if requested by the Trustees, provide advisory services directly to the Fund. In addition, the Manager provides certain administrative services to the Fund and the Portfolio under the Management Agreement.

For its services under the Fund’s Management Agreement, the Manager receives an investment management fee that is calculated daily and payable monthly according to the following schedule:

Each Fund pays the applicable annual rate based on its average daily net assets, less the amount, if any, of the Fund’s share of the management fee payable by its corresponding portfolio.

As the Fund was not operational prior to the date of this SAI, the Fund has not yet paid any management fees.

Any expense limitation arrangements in place during the Fund’s past three fiscal periods can be found in the Fund’s Prospectus in effect (as amended or supplemented from time to time) for such year.

Western Asset Management Company, LLC serves as the subadviser to the Fund and the Portfolio (the “Subadviser”) pursuant to a subadvisory agreement between the Manager and the Subadviser (the “Subadvisory Agreement”). The Subadviser has offices at 385 East Colorado Boulevard, Pasadena, California 91101 and 620 Eighth Avenue, New York, New York 10018. The Subadviser is a wholly-owned subsidiary of Legg Mason.

Under the Subadvisory Agreement, subject to the supervision of the Board and the Manager, the Subadviser regularly provides with respect to the portion of the Fund’s or the Portfolio’s assets allocated to it by the Manager, investment research, advice, management and supervision; furnishes a continuous investment program for the allocated assets consistent with the Fund’s or the Portfolio’s investment objectives, policies and restrictions; and places orders pursuant to its investment determinations. The Subadviser may delegate to companies that the Subadviser controls, is controlled by, or is under common control with, certain of the Subadviser’s duties under a Subadvisory Agreement, subject to the Subadviser’s supervision, provided the Subadviser will not be relieved of its duties or obligations under the Subadvisory Agreement as a result of any delegation.

The Subadvisory Agreement will continue in effect for its initial term and thereafter from year to year provided such continuance is specifically approved at least annually (a) by the Board or by a majority of the outstanding voting securities of the Fund (as defined in the 1940 Act), and (b) in either event, by a majority of the Independent Trustees with such Independent Trustees casting votes in person at a meeting called for such purpose. The Board or a majority of the outstanding voting securities of the Fund or the Portfolio (as applicable) (as defined in the 1940 Act) may terminate the Subadvisory Agreement without penalty, in each case on not more than 60 days’ nor less than 30 days’ written notice to the Subadviser. The Subadviser may terminate the respective Subadvisory Agreement, on 90 days’ written notice to the Fund or the Portfolio and the Manager. The Subadvisory Agreement may be terminated upon the mutual written consent of the Manager and the Subadviser. The Subadvisory Agreement will terminate automatically in the event of assignment (as defined in the 1940 Act) by the applicable Subadviser, and shall not be assignable by the Manager without the consent of the Subadviser.

The Subadvisory Agreement provides that the Subadviser, its affiliates performing services contemplated by the Subadvisory Agreement, and the partners, shareholders, directors, officers and employees of the Subadviser and such affiliates will not be liable for any error of judgment or mistake of law, or for any loss arising out of any investment, or for any act or

omission in the execution of securities transactions for the Fund or the Portfolio, but the Subadviser is not protected against any liability to the Fund or the Portfolio or the Manager to which the Subadviser would be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the Subadvisory Agreement.

As compensation for its services, the Manager pays to Western Asset a fee equal to 70% of the management fee paid to the Manager by the Fund or the Portfolio, net of any waivers and expense reimbursements.

In addition to amounts payable under the Management Agreement and the 12b-1 Plan (as discussed in this SAI), the Fund and the Portfolio is responsible for its own expenses, including, among other things: interest; taxes; governmental fees; voluntary assessments and other expenses incurred in connection with membership in investment company organizations; organization costs of the Fund; the cost (including interest, brokerage commissions, transaction fees or charges or acquired fund fees and expenses, if any) in connection with the purchase or sale of the Fund’s securities and other investments and any losses in connection therewith; fees and expenses of custodians, transfer agents, registrars, independent pricing vendors or other agents; legal expenses; loan commitment fees; expenses relating to the issuance and redemption or repurchase of the Fund’s shares or the Portfolio’s interests and servicing shareholder accounts; expenses of registering and qualifying the Fund’s shares for sale under applicable federal and state law; expenses of preparing, setting in print, printing and distributing prospectuses and statements of additional information and any supplements thereto, reports, proxy statements, notices and dividends to the Fund’s shareholders or the Portfolio’s investors; costs of stationery; website costs; costs of meetings of the Board or any committee thereof, meetings of shareholders and other meetings of the Fund or the Portfolio; Board fees; audit fees; travel expenses of officers, Trustees and employees of the Fund or the Portfolio, if any; the Fund’s or the Portfolio’s pro rata portion of premiums on any fidelity bond and other insurance covering the Fund and its officers, Trustees and employees; and litigation expenses and any non-recurring or extraordinary expenses as may arise, including, without limitation, those relating to actions, suits or proceedings to which the Fund or the Portfolio is a party and any legal obligation which the Fund or the Portfolio may have to indemnify the Fund’s or the Portfolio’s Trustees and officers with respect thereto.

Management may agree to implement an expense cap, waive fees and/or reimburse operating expenses for one or more classes of shares. Any such waived fees and/or reimbursed expenses are described in the Fund’s Prospectus. The expense caps and waived fees and/or reimbursed expenses do not cover extraordinary expenses, such as (a) any expenses or charges related to litigation, derivative actions, demand related to litigation, regulatory or other government investigations and proceedings, “for cause” regulatory inspections and indemnification or advancement of related expenses or costs, to the extent any such expenses are considered extraordinary expenses for the purposes of fee disclosure in Form N-1A as the same may be amended from time to time; (b) transaction costs (such as brokerage commissions and dealer and underwriter spreads) and taxes; (c) other extraordinary expenses as determined for the purposes of fee disclosure in Form N-1A, as the same may be amended from time to time; and (d) any other exclusions enumerated in the Fund’s particular expense cap. Without limiting the foregoing, extraordinary expenses are generally those that are unusual or expected to recur only infrequently, and may include such expenses, by way of illustration, as (i) expenses of the reorganization, restructuring, redomiciling or merger of the Fund or class or the acquisition of all or substantially all of the assets of another fund or class; (ii) expenses of holding, and soliciting proxies for, a meeting of shareholders of the Fund or class or a meeting of investors of a portfolio (except to the extent relating to routine items such as the election of Trustees or the approval of the independent registered public accounting firm); and (iii) expenses of converting to a new custodian, transfer agent or other service provider, in each case to the extent any such expenses are considered extraordinary expenses for the purposes of fee disclosure in Form N-1A as the same may be amended from time to time. In order to implement an expense limitation, the Manager will, as necessary, waive management fees or reimburse operating expenses. The Manager is also permitted to recapture amounts waived and/or reimbursed to the Fund during the same fiscal year if the Fund’s total annual operating expenses have fallen to a level below the Fund’s expense limitation. In no case will the Manager recapture any amount that would result, on any particular business day of the Fund, in the class’ total annual fund operating expenses exceeding such expense limitation or any other lower limit then in effect. These arrangements may be reduced or terminated under certain circumstances. The Manager may also waive management fees and/or reimburse the operating expenses of one or more portfolios, subject to recapture, under terms similar to the arrangements described above for the Fund.

The Fund has entered into an agreement with The Bank of New York Mellon (“BNY Mellon”), 240 Greenwich Street, New York, New York 10286, to serve as custodian of the Fund. BNY Mellon, among other things, maintains a custody account or accounts in the name of the Fund, receives and delivers all assets for the Fund upon purchase and upon sale or maturity, collects and receives all income and other payments and distributions on account of the assets of the Fund and makes disbursements on behalf of the Fund. BNY Mellon neither determines the Fund’s investment policies nor decides which securities the Fund will buy or sell. For its services, BNY Mellon receives a monthly fee based upon the daily average market value of securities held in custody and also receives securities transaction charges, including out-of-pocket expenses. The Fund may also periodically enter into arrangements with other qualified custodians with respect to certain types of securities or other transactions such as repurchase agreements or derivatives transactions. BNY Mellon may also act as the Fund’s securities lending agent and in that case would receive a share of the income generated by such activities.

BNY Mellon Investment Servicing (US) Inc. (“BNY”), located at 4400 Computer Drive, Westborough, Massachusetts 01581, serves as the Fund’s transfer agent. Under the transfer agency agreement with BNY, BNY maintains the shareholder account records for the Fund, handles certain communications between shareholders and the Fund and distributes dividends and distributions payable by the Fund. For these services, BNY receives a monthly fee computed on the basis of the number of shareholder accounts it maintains for the Fund during the month and is reimbursed for out-of-pocket expenses.

Morgan, Lewis & Bockius LLP, located at One Federal Street, Boston, Massachusetts 02110, serves as legal counsel to the Trust and the Fund.

PricewaterhouseCoopers LLP, 100 East Pratt Street, Suite 2600, Baltimore, Maryland 21202 serves as the Fund’s independent registered public accounting firm.

Pursuant to the Subadvisory Agreement and subject to the general supervision of the Board and in accordance with the Fund’s investment objectives and strategies, the Subadviser is responsible for the execution of the Fund’s portfolio transactions with respect to assets allocated to the Subadviser. The Subadviser is authorized to place orders pursuant to its investment determinations for the Fund either directly with the issuer or with any broker or dealer, foreign currency dealer, futures commission merchant or others selected by it.

In certain instances, there may be securities that are suitable as an investment for the Fund as well as for one or more of the other clients of the Subadviser. Investment decisions for the Fund and for the Subadviser’s other clients are made with a view to achieving their respective investment objectives. It may develop that a particular security is bought or sold for only one client even though it might be held by, or bought or sold for, other clients. Likewise, a particular security may be bought for one or more clients when one or more clients are selling the same security. Some simultaneous transactions are inevitable when several clients receive investment advice from the same investment adviser, particularly when the same security is suitable for the investment objectives of more than one client. When two or more clients are simultaneously engaged in the purchase or sale of the same security, the securities are allocated among clients in a manner believed to be equitable to each. It is recognized that in some cases this system could adversely affect the price of or the size of the position obtainable in a security for the Fund. When purchases or sales of the same security for the Fund and for other portfolios managed by the Subadviser occur contemporaneously, the purchase or sale orders may be aggregated in order to obtain any price advantages available to large volume purchases or sales.

Transactions on stock exchanges and other agency transactions involve the payment of negotiated brokerage commissions by the Fund. Transactions in foreign securities often involve the payment of brokerage commissions that may be higher than those in the United States. Fixed income securities are generally traded on a net basis (i.e., without a commission) through dealers acting as principal for their own account and not as brokers. This means that a dealer makes a market for securities by offering to buy at one price and selling the security at a slightly higher price. The difference between the prices is

known as a “spread.” Other portfolio transactions may be executed through brokers acting as agents and the Fund will pay a spread or commission in connection with such transactions. The cost of securities purchased from underwriters includes an underwriting commission, concession or a net price. The Fund may also purchase securities directly from the issuer. The aggregate brokerage commissions paid by the Fund for the three most recent fiscal years or periods, as applicable, are set forth below under “Aggregate Brokerage Commissions Paid.”

The general policy of the Subadviser in selecting brokers and dealers is to obtain the best results achievable in the context of a number of factors which are considered both in relation to individual trades and broader trading patterns. The Fund may not always pay the lowest commission or spread available. Rather, in placing orders on behalf of the Fund, the Subadviser also takes into account other factors bearing on the overall quality of execution, such as size of the order, difficulty of execution, the reliability of the broker/dealer, the competitiveness of the price and the commission, the research services received and whether the broker/dealer commits its own capital.

In connection with the selection of such brokers or dealers and the placing of such orders, subject to applicable law, brokers or dealers may be selected who also provide brokerage and research services (as those terms are defined in Section 28(e) of the 1934 Act) to the Fund and/or the other accounts over which the Subadviser or its affiliates exercise investment discretion. The Subadviser is authorized to pay a broker or dealer that provides such brokerage and research services a commission for executing a portfolio transaction for the Fund which is in excess of the amount of commission another broker or dealer would have charged for effecting that transaction if the Subadviser determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage and research services provided by such broker or dealer. Investment research services include information and analysis on particular companies and industries as well as market or economic trends and portfolio strategy, market quotations for portfolio evaluations, analytical software and similar products and services. If a research service also assists the Subadviser in a non-research capacity (such as bookkeeping or other administrative functions), then only the percentage or component that provides assistance to the Subadviser in the investment decision making process may be paid in commission dollars. This determination may be viewed in terms of either that particular transaction or the overall responsibilities that the Subadviser and its affiliates have with respect to accounts over which they exercise investment discretion. The Subadviser may also have arrangements with brokers pursuant to which such brokers provide research services to the Subadviser in exchange for a certain volume of brokerage transactions to be executed by such brokers. While the payment of higher commissions increases the Fund’s costs, the Subadviser does not believe that the receipt of such brokerage and research services significantly reduces its expenses as Subadviser. Arrangements for the receipt of research services from brokers (so-called “soft dollar” arrangements) may create conflicts of interest. Although the Subadviser is authorized to use soft dollar arrangements in order to obtain research services, it is not required to do so, and the Subadviser may not be able or may choose not to use soft dollar arrangements because of regulatory restrictions, operational considerations or for other reasons.

Research services furnished to the Subadviser by brokers that effect securities transactions for the Fund may be used by the Subadviser in servicing other investment companies and accounts which the Subadviser manages. Similarly, research services furnished to the Subadviser by brokers that effect securities transactions for other investment companies and accounts which the Subadviser manages may be used by the Subadviser in servicing the Fund. Not all of these research services are used by the Subadviser in managing any particular account, including the Fund.

Firms that provide research and brokerage services to the Subadviser may also promote the sale of the Fund or other pooled investment vehicles advised by the Subadviser, and the Subadviser and/or its affiliates may separately compensate them for doing so. Such brokerage business is placed on the basis of brokerage and research services provided by the firm and is not based on any sales of the Fund or other pooled investment vehicles advised by the Subadviser.

The Fund contemplates that, consistent with the policy of obtaining the best net results, brokerage transactions may be conducted through “affiliated broker/dealers,” as defined in the 1940 Act. The Fund’s Board has adopted procedures in accordance with Rule 17e-1 under the 1940 Act to ensure that all brokerage commissions paid to such affiliates are reasonable and fair in the context of the market in which such affiliates operate. For the three most recent fiscal periods (as applicable), the Fund did not pay any brokerage commission to its affiliates.

For the fiscal period ended August 31, 2019, the Fund did not direct any brokerage transactions related to research services and did not pay any brokerage commissions related to research services.

No historical information regarding brokerage commissions paid for portfolio transactions is given because the Fund is newly offered. In addition, no historical information regarding directed brokerage transactions

or brokerage commissions paid in relation to research services is given because the Fund is newly offered.

No historical information regarding securities issued by the Fund’s broker/dealers held by the Fund is given because the Fund is newly offered.

Since the Fund is newly offered, there is no historical data regarding share ownership.

Legg Mason Investor Services, LLC, a wholly-owned broker/dealer subsidiary of Legg Mason, located at 100 International Drive, Baltimore, Maryland 21202, serves as the sole and exclusive distributor of the Fund pursuant to a written agreement (as amended, the “Distribution Agreement”). The Distributor also serves as exclusive placement agent with respect to the Portfolio.

Under the Distribution Agreement, the Distributor is appointed as principal underwriter and distributor in connection with the offering and sale of shares of the Fund. The Distributor offers the shares on an agency or “best efforts” basis under which the Fund issues only the number of shares actually sold. Shares of the Fund are continuously offered by the Distributor.

The Distribution Agreement is renewable from year to year with respect to the Fund if approved (a) by the Board or by a vote of a majority of the Fund’s outstanding voting securities, and (b) by the affirmative vote of a majority of Trustees who are not parties to such agreement or interested persons of any party by votes cast in person at a meeting called for such purpose.

The Distribution Agreement is terminable with respect to the Fund without penalty by the Board or by vote of a majority of the outstanding voting securities of the Fund, or by the Distributor, on not less than 60 days’ written notice to the other party (unless the notice period is waived by mutual consent). The Distribution Agreement will automatically and immediately terminate in the event of its assignment.

The Distributor may be deemed to be an underwriter for purposes of the 1933 Act.

The Distributor, the Manager, their affiliates and their personnel have interests in promoting sales of the Legg Mason Funds, including remuneration, fees and profitability relating to services to and sales of the funds. Associated persons of the Manager, the Distributor or their affiliates (including wholesalers registered with the Distributor) may receive additional compensation related to the sale of individual Legg Mason Funds or categories of Legg Mason Funds. The Manager, the Subadviser(s), and their advisory or other personnel may also benefit from increased amounts of assets under management.

Service Agents also may benefit from the sales of shares of the Legg Mason Funds. For example, in connection with such sales, Service Agents may receive compensation from the Fund (with respect to the Fund as a whole or a particular class of shares) and/or from the Manager, the Distributor, and/or their affiliates, as further described below. The structure of these compensation arrangements, as well as the amounts paid under such arrangements, vary and may change from time to time. In addition, new compensation arrangements may be negotiated at any time. The compensation arrangements described in this section are not mutually exclusive, and a single Service Agent may receive multiple types of compensation.

The Distributor has agreements in place with Service Agents defining how much each firm will be paid for the sale of the Fund from sales charges, if any, paid by Fund shareholders and from 12b-1 Plan fees paid to the Distributor by the Fund. These Service Agents then pay their employees or associated persons who sell such fund shares from the sales charges and/or

fees they receive. The Service Agent, and/or its employees or associated persons may receive a payment when a sale is made and will, in most cases, continue to receive ongoing payments while you are invested in the Fund. In other cases, the Distributor may retain all or a portion of such fees and sales charges.

In addition, the Distributor, the Manager and/or certain of their affiliates may make additional payments (which are often referred to as “revenue sharing” payments) to the Service Agents from their past profits and other available sources, including profits from their relationships with the Fund. Revenue sharing payments are a form of compensation paid to a Service Agent in addition to the sales charges paid by Fund shareholders or 12b-1 Plan fees paid by the Fund. the Manager, the Distributor and/or certain of its affiliates may revise the terms of any existing revenue sharing arrangement and may enter into additional revenue sharing arrangements with other Service Agents.

Revenue sharing arrangements are intended, among other things, to foster the sale of Fund shares and/or to compensate financial services firms for assisting in marketing or promotional activities in connection with the sale of Fund shares. In exchange for revenue sharing payments, the Manager and the Distributor generally expect to receive the opportunity for the Fund to be sold through the Service Agents’ sales forces or to have access to third-party platforms or other marketing programs, including but not limited to mutual fund “supermarket” platforms or other sales programs. To the extent that Service Agents receiving revenue sharing payments sell more shares of the Fund, the Manager and the Distributor and/or their affiliates benefit from the increase in Fund assets as a result of the fees they receive from the Fund. The Distributor, LMPFA or their affiliates consider revenue sharing arrangements based on a variety of factors and services to be provided.

Revenue sharing payments are usually calculated based on a percentage of Fund sales and/or Fund assets attributable to a particular Service Agent. Payments may also be based on other criteria or factors such as, for example, a fee per each transaction. Specific payment formulas are negotiated based on a number of factors, including, but not limited to, reputation in the industry, ability to attract and retain assets, target markets, customer relationships and scope and quality of services provided. In addition, the Distributor, the Manager and/or certain of their affiliates may pay flat fees on a one-time or irregular basis for the initial set-up of the fund on a Service Agent’s systems, participation or attendance at a Service Agent’s meetings, or for other reasons. In addition, the Distributor, the Manager and/or certain of their affiliates may pay certain education and training costs of Service Agents (including, in some cases, travel expenses) to train and educate the personnel of the Service Agents. It is likely that Service Agents that execute portfolio transactions for the Fund will include those firms with which the Manager, the Distributor and/or certain of their affiliates have entered into revenue sharing arrangements.

The Fund generally pays the transfer agent for certain recordkeeping and administrative services. In addition, the Fund may pay Service Agents for certain recordkeeping, administrative, sub-accounting and networking services. These services include maintenance of shareholder accounts by the firms, such as recordkeeping and other activities that otherwise would be performed by a Fund’s transfer agent. Administrative fees may be paid to a firm that undertakes, for example, shareholder communications on behalf of the Fund. Networking services are services undertaken to support the electronic transmission of shareholder purchase and redemption orders through the National Securities Clearing Corporation (“NSCC”). These payments are generally based on either (1) a percentage of the average daily net assets of Fund shareholders serviced by a Service Agent or (2) a fixed dollar amount for each account serviced by a Service Agent. the Distributor, the Manager and/or their affiliates may make all or a portion of these payments.

In addition, the Fund reimburses the Distributor for NSCC fees that are invoiced to the Distributor as the party to the agreement with NSCC for the administrative services provided by NSCC to the Fund and its shareholders. These services include transaction processing and settlement through Fund/SERV, electronic networking services to support the transmission of shareholder purchase and redemption orders to and from Service Agents, and related recordkeeping provided by NSCC to the Fund and its shareholders.

If your Fund shares are purchased through a retirement plan, the Distributor, the Manager or certain of their affiliates may also make similar payments to those described in this section to the plan’s recordkeeper or an affiliate.

Revenue sharing payments, as well as the other types of compensation arrangements described in this section, may provide an incentive for Service Agents and their employees or associated persons to recommend or sell shares of the Fund to customers and in doing so may create conflicts of interest between the firms’ financial interests and the interests of their customers. The total amount of these payments is substantial, may be substantial to any given recipient and may exceed the costs and expenses incurred by the recipient for any Fund-related marketing or shareholder servicing activities.

As of December 31, 2018, the Distributor, the Manager or their affiliates made revenue sharing payments to the Service Agents listed below (or their affiliates or successors). It is possible that each Service Agent listed is not receiving payments with respect to each fund in the Legg Mason Fund complex. This list of intermediaries will change over time, and any additions, modifications or deletions thereto that have occurred since December 31, 2018 are not reflected.

MSCS Financial Services Division of Broadridge Business Process Outsourcing, LLC

The Distributor, the Manager or their affiliates may also pay fees, from their own assets, to Service Agents for providing other distribution-related services as well as recordkeeping, administrative, subaccounting, and networking services (or portions thereof), and other shareholder or administrative services in connection with investments in the Fund. These payments may be considered revenue sharing payments. The Service Agents receiving such payments may not be listed above.

You should assume that your Service Agent receives revenue sharing payments and/or other compensation described in this SAI. Please contact your Service Agent for details about any payments it (and its employees) may receive from the Fund and/or from the Distributor, the Manager and/or their affiliates. You should review your Service Agent’s disclosure and/or talk to your Service Agent to obtain more information on how this compensation may have influenced your Service Agent’s recommendation of the Fund.

From time to time, the Distributor or the Manager, at its expense, may provide compensation or promotional incentives (“concessions”) to dealers that sell or arrange for the sale of shares of the Fund or a managed account strategy of which the Fund is part. Such concessions provided by the Distributor or the Manager may include financial assistance to dealers in connection with preapproved conferences or seminars, sales or training programs for invited registered representatives and other employees, payment for travel expenses, including lodging, incurred by registered representatives and other employees for such seminars or training programs, seminars for the public, advertising and sales campaigns regarding one or more funds, and/or other dealer-sponsored events. From time to time, the Distributor or the Manager may make expense reimbursements for special training of a dealer’s registered representatives and other employees in group meetings or to help pay the expenses of sales contests. Other concessions may be offered to the extent not prohibited by applicable laws or any self-regulatory agency, such as the FINRA.

Purchases of Fund shares are discussed under the “Buying shares” and “Exchanging shares” sections of the Fund’s Prospectus; this information is incorporated herein by reference. See the Fund’s Prospectus for a discussion of which share classes of the Fund are available for purchase, who is eligible to purchase shares of each class, and applicable investment minimums.

Investors may purchase shares from a Service Agent. However, Service Agents may not offer all classes of shares. In addition, certain investors may purchase shares directly from the Fund. When purchasing shares of the Fund, investors must specify the class of shares being purchased. Payment must be made with the purchase order. Service Agents may charge their customers an annual account maintenance fee in connection with a brokerage or other financial account through which an investor purchases or holds shares. Accounts held directly at the transfer agent are not subject to a maintenance fee.

Capital Shares and Premium Shares are not available to individual investors. Premium Shares are available to funds affiliated with LMPFA and/or its affiliates. However, Premium Shares may also be available to other investors approved by the Distributor.

The Fund reserves the right to waive or change minimums, to decline any order to purchase shares and to suspend the offering of shares from time to time.

Redemptions of Fund shares are discussed under the “Exchanging shares” and “Redeeming shares” sections of the Fund’s Prospectus; this information is incorporated herein by reference.

If a shareholder holds shares in more than one class, any request for redemption must specify the class being redeemed. In the event of a failure to specify which class, or if the investor owns fewer shares of the class than specified, the redemption request will be delayed until the transfer agent receives further instructions.

The Service Agent may charge you a fee for executing your order. The amount and applicability of such a fee is determined and should be disclosed to its customers by each Service Agent.

Additional Information Regarding Telephone Redemption and Exchange Program. The Fund reserves the right to suspend, modify or discontinue the telephone redemption and exchange program.

The Fund may impose a liquidity fee on redemptions from the Fund (up to 2%) or temporarily restrict redemptions from the Fund for up to 10 business days (a “redemption gate”), in the event that the Fund’s weekly liquid assets¹ fall below the following thresholds:

If the Fund imposes a redemption gate, the Fund and the Fund’s authorized agent or intermediary will not accept redemption orders until the Fund has notified shareholders that the redemption gate has been lifted. Any redemption orders submitted while a redemption gate is in effect will be cancelled without further notice.

Pending redemption orders may be affected if the Fund imposes a redemption gate. If you still wish to redeem shares once the redemption gate has been lifted, you will need to submit a new redemption request to the Fund or the Fund’s authorized agent or intermediary.

Liquidity fees and redemption gates may be terminated at any time at the discretion of the Board. In addition, liquidity fees and redemption gates will terminate at the beginning of the next business day once the Fund has invested 30% or more of its total assets in weekly liquid assets. The Fund may only suspend redemptions for up to 10 business days in any 90-day period.

A liquidity fee imposed by the Fund will reduce the amount you will receive upon the redemption of your shares, and could cause you to recognize a capital loss or could decrease the capital gain or increase the capital loss you would otherwise recognize. Liquidity fees would be retained by the Fund. Pending redemption orders may be affected if the Fund imposes a liquidity fee.

Any announcement regarding the imposition of a liquidity fee or redemption gate, or the termination of a liquidity fee or a redemption gate, will be available at the Fund’s website as noted below, and will be filed with the SEC.

Premier Institutional Liquid Reserves: www.leggmason.com/en-us/products/money-markets/western-asset-premier-institutional-liquid-reserves.html

If the Fund’s weekly liquid assets fall below 10% of the Fund’s total assets, the Fund reserves the right to permanently suspend redemptions and liquidate if the Board determines that it is not in the best interests of the Fund to continue operating.

Subject to applicable law, the Fund may cause a shareholder’s shares to be redeemed under certain circumstances, including in order to eliminate small accounts for administrative efficiencies and cost savings, to protect the tax status of the Fund if necessary and to eliminate ownership of shares by a particular shareholder when the Fund determines, pursuant to adopted policies, that the particular shareholder’s ownership is not in the best interests of the other shareholders of the Fund (for example, in the case of a market timer).

The Fund reserves the right, under certain conditions, to honor any request for a redemption by making payment in whole or in part by delivering securities valued in accordance with the procedures described under “Share price/ Fund business days” in the Fund’s Prospectus. Because redemption in kind may be used at times of unusual illiquidity in the markets, these valuation methods may include fair value estimations. If payment is made in securities, a shareholder should expect to incur brokerage expenses in converting those securities into cash, and the market price of those securities will be subject to fluctuation until they are sold. The securities delivered may not be representative of the entire Fund portfolio, may represent only one issuer or a limited number of issuers and may be securities that the Fund would otherwise sell. The Fund will not use securities to pay redemptions by LMIS or other affiliated persons of the Fund, except as permitted by law, SEC rules or orders, or interpretive guidance from the SEC staff or other proper authorities.

Exchanges of Fund shares are discussed under the Buying shares”, “Exchanging shares” and “Redeeming shares” sections of the Fund’s Prospectus; this information is incorporated herein by reference. The exchange privilege enables shareholders to acquire shares of the same class in another fund sold by the Distributor. This privilege is available to shareholders residing in any state in which the fund shares being acquired may legally be sold. Prior to any exchange, the shareholder should obtain and review a copy of the current prospectus of each fund into which an exchange is being considered. The Prospectus describes the requirements for exchanging shares of the Fund and may be obtained as described on the cover page of this SAI.

Upon receipt of proper instructions and all necessary supporting documents, shares submitted for exchange are redeemed at the then-current NAV, and the proceeds, net of any applicable sales charge, are immediately invested in shares of the fund being acquired at that fund’s then current NAV. The Distributor reserves the right to reject any exchange request. The exchange privilege may be modified or terminated at any time after written notice to shareholders.

The exchange privilege is not available with respect to Premier Institutional Liquid Reserves.

Capital Shares and Premium Shares may be exchanged for the same class of shares of another Western Asset money market fund sold by the Distributor without imposition of any charge.

The Fund is not designed to provide investors with a means of speculation on short-term market movements. A pattern of frequent exchanges by investors can be disruptive to efficient portfolio management and, consequently, can be detrimental to the Fund and its shareholders. See “Frequent trading of fund shares” in the Fund’s Prospectuses.

During times of drastic economic or market conditions, the Fund may suspend the exchange privilege temporarily without notice and treat exchange requests based on their separate components—redemption orders with a simultaneous request to purchase the other fund’s shares. In such a case, the redemption request would be processed at the Fund’s next determined NAV but the purchase order would be effective only at the NAV next determined after the fund being purchased formally accepts the order, which may result in the purchase being delayed.

The exchange privilege may be modified or terminated at any time, and is available only in those jurisdictions where such exchanges legally may be made. An exchange is treated as a sale of the shares exchanged and could result in taxable gain or loss to the shareholder making the exchange. A shareholder generally will not recognize a gain or loss on an exchange if the fund whose shares are exchanged maintains a NAV of $1.00 per share. Other taxes or tax-related consequences may apply, and you should consult your tax adviser before requesting an exchange.

The NAV per share of each class of the Fund is determined on such days and at such times as is set forth in the Fund’s Prospectus. NAV is calculated for each class of the Fund by dividing the value of the Fund’s net assets (i.e., the value of its assets attributable to a class, including (if applicable) its investment in its underlying Portfolio, if any, less its liabilities, including expenses payable or accrued) by the number of the shares of the class outstanding at the time the determination is made. As of the date of this SAI, the NYSE is normally open for trading every weekday except in the event of an emergency or for the following holidays (or the days on which they are observed): New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Federal Reserve Bank of New York is closed for the following holidays (or the days on which they are observed): New Year’s Day, Martin Luther King Jr. Day, Presidents’ Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving Day and Christmas Day. As of the date of this SAI, the Securities Industry and Financial Markets Association (SIFMA) recommends an early close to the bond markets on Good Friday, the business day following Thanksgiving Day and the business day preceding the following holidays (or the days on which they are observed): New Year’s Day, Good Friday, Memorial Day, Independence Day and Christmas Day.

The value of the Portfolio’s net assets (i.e., the value of its securities and other assets less its liabilities, including expenses payable or accrued) is determined at the same times and on the same days as the NAV per share of the corresponding Fund is determined (although the Portfolio’s NAV may also be determined at other times in addition to these times to accommodate the NAV times of other investors in the Portfolio). The NAV of the Fund’s investment in its corresponding Portfolio is equal to the Fund’s pro rata share of the total investment of the Fund and of other investors in the Portfolio less the Fund’s pro rata share of the Portfolio’s liabilities.

Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves:

The Fund seeks to maintain a constant $1.00 NAV per share and, although no assurance can be given that it will be able to do so on a continuing basis, as described below, the Fund employs specific investment policies and procedures to accomplish this result.

The securities held by the Fund or the Portfolio are valued at their amortized cost. Amortized cost valuation involves valuing an instrument at its cost and thereafter assuming a constant amortization to maturity of any discount or premium. If the market value (or deemed market value) of the securities held by the Fund or the Portfolio deviates more than 1/2 of 1% from their value determined on the basis of amortized cost, the applicable Board will consider whether any action should be initiated, as described in the following paragraph. Although the amortized cost method provides certainty in valuation, it may result in periods during which the stated value of an instrument is higher or lower than the price the Fund or Portfolio would receive if the instrument were sold.

Pursuant to the rules of the SEC, the Fund’s and Portfolio’s Trustees have established procedures to stabilize the value of the Fund’s and Portfolio’s net assets within 1/2 of 1% of the value determined on the basis of amortized cost. These procedures include a review of the extent of any such deviation of NAV, based on available market rates. Should that deviation exceed 1/2 of 1% for the Fund or the Portfolio (as applicable), the Trustees will consider whether any action should be initiated to eliminate or reduce material dilution or other unfair results to investors in the Fund or the Portfolio. Such action may include redemption or withdrawal in kind, selling securities prior to maturity and utilizing a NAV as determined by using available market quotations.

Because of the short-term maturities of the portfolio investments of the Fund, the Fund does not expect to realize any material long-term capital gains or losses. Any net realized short-term capital gains will be declared and distributed to the Fund’s shareholders annually after the close of the Fund’s fiscal year. Distributions of short-term capital gains are taxable to shareholders as ordinary income. Any realized short-term capital losses will be offset against short-term capital gains or, to the extent possible, utilized as capital loss carryover. The Fund may distribute short-term capital gains more frequently than annually, and the Fund, other than Institutional Government Reserves may reduce shares to reflect capital losses or make distributions of capital if necessary, in each case in order to maintain the Fund’s or Portfolio’s NAV of $1.00 per share. Reducing the number of shares would be accomplished by means of a reverse stock split, if authorized by the Fund’s Trustees. In a reverse stock split, the number of shares held by each shareholder would be reduced by the same proportional amount. That amount would be

calculated such that, immediately after the reverse stock split, each outstanding share would be valued at $1.00. However, each shareholder would own fewer shares and, therefore, would have lost money.

It is expected that the Fund (and each class of the Fund) will have a positive net income at the time of each determination thereof. If for any reason the Fund’s or a class’ net income is a negative amount, which could occur, for instance, upon default by an issuer of a portfolio security, or if the Fund’s expenses exceeded its income, the Fund would first offset the negative amount with respect to each shareholder account in the Fund or class from the dividends declared during the month with respect to those accounts. If and to the extent that negative net income exceeds declared dividends at the end of the month, the Fund may reduce the number of outstanding shares of the Fund or class as described above. In addition, even where the Fund does not have negative income, the Fund may retain some portion of its income, which would have the effect of increasing its NAV.

Valuation of the Fund’s securities and other assets is performed in accordance with procedures approved by the Board. These procedures delegate most valuation functions to the Manager, which generally uses independent third party pricing services approved by the Board. Under the procedures, assets are valued as follows:

Many factors may influence the price at which the Fund could sell any particular portfolio investment. The sales price may well differ—higher or lower—from the Fund’s last valuation, and such differences could be significant, particularly for securities that trade in relatively thin markets and/or markets that experience extreme volatility. Moreover, valuing securities using fair value methodologies involves greater reliance on judgment than valuing securities based on market quotations. A fund that uses fair value methodologies may value those securities higher or lower than another fund using market quotations or its own fair value methodologies to price the same securities. There can be no assurance that the Fund could obtain the value assigned to a security if it were to sell the security at approximately the time at which the Fund determines its NAV. Investors who purchase or redeem fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology. Because of the differences in distribution fees and class-specific expenses, the per share NAV of each class may differ.

Because of the short-term maturities of the portfolio investments of the Fund, the Fund does not expect to realize any material long-term capital gains or losses. Any net realized short-term capital gains will be declared and distributed to the Fund’s shareholders annually after the close of the Fund’s fiscal year. Distributions of short-term capital gains are taxable to shareholders as ordinary income. Any realized short-term capital losses will be offset against short-term capital gains or, to the extent possible, utilized as capital loss carryover. The Fund may distribute short-term capital gains more frequently than annually, reduce shares to reflect capital losses or make distributions of capital. Reducing the number of shares would be accomplished by means of a reverse stock split, if authorized by the Fund’s Trustees. In a reverse stock split, the number of shares held by each shareholder would be reduced by the same proportional amount.

The Manager delegates to the Subadviser the responsibility for voting proxies for the Fund through its contracts with the Subadviser. The Subadviser may use its own proxy voting policies and procedures to vote proxies of the Fund if the Fund’s Board reviews and approves the use of those policies and procedures. Accordingly, the Manager does not expect to have proxy-voting responsibility for the Fund.

Should the Manager become responsible for voting proxies for any reason, such as the inability of the Subadviser to provide investment advisory services, the Manager shall utilize the proxy voting guidelines established by the most recent Subadviser to vote proxies until a new Subadviser is retained and the use of its proxy voting policies and procedures is authorized by the Board. In the case of a material conflict between the interests of the Manager (or its affiliates if such conflict is known to persons responsible for voting at the Manager) and any fund, the Board of Directors of the Manager shall consider how to address the conflict and/or how to vote the proxies. The Manager shall maintain records of all proxy votes in accordance with applicable securities laws and regulations.

The Manager shall be responsible for gathering relevant documents and records related to proxy voting from the Subadviser and providing them to the Fund as required for the Fund to comply with applicable rules under the 1940 Act. The Manager shall also be responsible for coordinating the provision of information to the Board with regard to the proxy voting policies and procedures of the Subadviser, including the actual proxy voting policies and procedures of the Subadviser, changes to such policies and procedures, and reports on the administration of such policies and procedures.

The Subadviser’s proxy voting policies and procedures govern in determining how proxies relating to the Fund’s portfolio securities are voted. A copy of the proxy voting policies and procedures is attached as Appendix A to this SAI. Information regarding how the Fund voted proxies (if any) relating to portfolio securities during the most recent twelve month period ended June 30 is available without charge (1) by calling 1-877-721-1926, (2) on www.leggmason.com/moneymarketfunds (click on the name of the Fund) and (3) on the SEC’s website at http://www.sec.gov.

The Fund’s Board has adopted policies and procedures (the “policy”) developed by the Manager with respect to the disclosure of the Fund’s portfolio securities and any ongoing arrangements to make available information about the Fund’s portfolio securities for the Legg Mason Funds. The Manager believes the policy is in the best interests of the Fund and its shareholders and that it strikes an appropriate balance between the desire of investors for information about fund portfolio holdings and the need to protect the Fund from potentially harmful disclosures.

The policy provides that information regarding the Fund’s portfolio holdings may be shared at any time with employees of the Manager, the Subadviser and other affiliated parties involved in the management, administration or operations of the Fund (referred to as fund-affiliated personnel). Under the policy, the Fund’s complete list of holdings (including the size of each position) and certain other information is disclosed as of the last business day of the month no later than five business days after month-end on the Fund’s public website. The Fund may disclose its complete portfolio holdings earlier, provided such information has been made available on the Fund’s public website in accordance with the policy.

The Fund currently discloses its complete portfolio holdings as of the last business day of each month no later than five business days after month-end on www.leggmason.com/moneymarketfunds (click on the name of the Fund).

Under the policy, the Fund may release portfolio holdings information on a regular basis to a custodian, sub-custodian, fund accounting agent, proxy voting provider, rating agency or other vendor or service provider for a legitimate business purpose, where the party receiving the information is under a duty of confidentiality, including a duty to prohibit the sharing of non-public information with unauthorized sources and trading upon non-public information. The Fund may enter into other ongoing arrangements for the release of portfolio holdings information, but only if such arrangements serve a legitimate business purpose and are with a party who is subject to a confidentiality agreement and restrictions on trading upon non-public information. None of the Fund, Legg Mason or any other affiliated party may receive compensation or any other consideration in connection with

such arrangements. Ongoing arrangements to make available information about the Fund’s portfolio securities will be reviewed at least annually by the Fund’s Board.

Set forth below is a list, as of June 30, 2018, of those parties with whom the Manager, on behalf of the Fund, has authorized ongoing arrangements that include the release of portfolio holdings information in accordance with the policy, as well as the maximum frequency of the release under such arrangements, and the minimum length of the lag, if any, between the date of the information and the date on which the information is disclosed. The ongoing arrangements may vary for each party, and it is possible that not every party will receive information for the Fund. The parties identified below as recipients are service providers, fund rating agencies, consultants and analysts.

Portfolio holdings information for the Fund may also be released from time to time pursuant to ongoing arrangements with the following parties:

Excluded from the lists of ongoing arrangements set forth above are ongoing arrangements where either (i) the disclosure of portfolio holdings information occurs concurrently with or after the time at which the portfolio holdings information is included in a public filing with the SEC that is required to include the information, or (ii) the Fund’s portfolio holdings information is made available no earlier than the day next following the day on which the Fund makes the information available on its website, as disclosed in the Fund’s Prospectus. The approval of the Fund’s Chief Compliance Officer, or designee, must be obtained before entering into any new ongoing arrangement or altering any existing ongoing arrangement to make available portfolio holdings information, or with respect to any exceptions from the policy.

In addition to the ongoing arrangements described above, the Fund’s complete or partial list of holdings (including size of positions) may be released to another party on a one-time basis, provided the party receiving the information has executed a non-disclosure and confidentiality agreement and provided that the specific release of information has been approved by the Fund’s Chief Compliance Officer or designee as consistent with the policy. By way of illustration and not of limitation, release of non-public information about a Fund’s portfolio holdings may be made (i) to a proposed or potential adviser or Subadviser(s) or

other investment manager asked to provide investment management services to the Fund, or (ii) to a third party in connection with a program or similar trade.

In addition, the policy permits the release to investors, potential investors, third parties and Legg Mason personnel that are not fund-affiliated personnel of limited portfolio holdings information in other circumstances, including:

The Fund’s Chief Compliance Officer, or designee, may as is deemed appropriate, approve exceptions from the policy. Exceptions are granted only after a thorough examination and consultation with the Manager’s legal department, as necessary. Exceptions from the policy are reported annually to the Fund’s Board.

The Fund’s portfolio holdings policy is designed to prevent sharing of portfolio information with third parties that have no legitimate business purpose for accessing the information. The policy may not be effective to limit access to portfolio holdings information in all circumstances, however. For example, the Manager or the Subadviser may manage accounts other than the Fund that have investment objectives and strategies similar to those of the Fund. Because these accounts, including the Fund, may be similarly managed, portfolio holdings may be similar across the accounts. In that case, an investor in another account managed by the Manager or the Subadviser may be able to infer the portfolio holdings of the Fund from the portfolio holdings in that investor’s account.

The certificate of trust to establish the Trust was filed with the State Department of Assessments and Taxation of Maryland on October 4, 2006. The Fund is a series of the Trust.

The Trust is a Maryland statutory trust. A Maryland statutory trust is an unincorporated business association that is established under, and governed by, Maryland law. Maryland law provides a statutory framework for the powers, duties, rights and obligations of the Trustees and shareholders of a statutory trust, while the more specific powers, duties, rights and obligations of the Trustees and the shareholders are determined by the trustees as set forth in a trust’s declaration of trust. The Trust’s Declaration of Trust (the “Declaration”) provides that by becoming a shareholder of the Fund, each shareholder shall be expressly held to have agreed to be bound by the provisions of the Declaration and any other governing instrument of the Trust, such as the by-laws of the Trust, which contain additional rules governing the conduct of the business of the Trust.

Some of the more significant provisions of the Declaration are summarized below. The following summary is qualified in its entirety by reference to the applicable provisions of the Declaration.

Under the Declaration, the Trustees have broad authority to direct the business and affairs of the Trust. The Declaration provides for shareholder voting as required by the 1940 Act or other applicable laws but otherwise permits, consistent with Maryland law, actions by the Trustees without seeking the consent of shareholders. For example, the Trustees are empowered to amend the Declaration or authorize the merger or consolidation of the Trust into another trust or entity, reorganize the Trust or any series or class into another trust or entity or a series or class of another entity, sell all or substantially all of the assets of the Trust or any series or class to another entity, or a series or class of another entity, terminate the Trust or any series or class, or adopt or amend the by-laws of the Trust, in each case without shareholder approval if the 1940 Act would not require such approval.

The Fund is not required to hold an annual meeting of shareholders, but the Fund will call special meetings of shareholders whenever required by the 1940 Act or by the terms of the Declaration. The Declaration provides for “dollar-weighted voting” which means that a shareholder’s voting power is determined, not by the number of shares he or she owns, but by the dollar value of those shares determined on the record date. All shareholders of record of all series and classes of the Trust vote together, except where required by the 1940 Act to vote separately by series or by class, or when the Trustees have determined that a matter affects only the interests of one or more series or classes of shares. There is no cumulative voting on any matter submitted to a vote of the shareholders.

The Declaration provides that the Trustees may establish the number of Trustees and that vacancies on the Board may be filled by the remaining Trustees, except when election of Trustees by the shareholders is required under the 1940 Act. When a vote of shareholders is required to elect Trustees, the Declaration provides that such Trustees shall be elected by a plurality of votes cast by shareholders at a meeting at which a quorum is present. The Declaration also provides that a mandatory retirement age may be set by action of two-thirds of the Trustees and that Trustees may be removed, with or without cause, by a vote of shareholders holding two-thirds of the voting power of the Trust, or by a vote of two-thirds of the remaining Trustees. The provisions of the Declaration relating to the election and removal of Trustees may not be amended without the approval of two-thirds of the Trustees.

The Trustees are authorized to amend the Declaration without the vote of shareholders, but no amendment may be made that impairs the exemption from personal liability granted in the Declaration to persons who are or have been shareholders, Trustees, officers or, employees of the Trust or that limits the rights to indemnification, advancement of expenses or insurance provided in the Declaration with respect to actions or omissions of persons entitled to indemnification, advancement of expenses or insurance under the Declaration prior to the amendment.

The Fund may issue an unlimited number of shares for such consideration and on such terms as the Trustees may determine. All shares offered pursuant to the Prospectus of the Fund, when issued, will be fully paid and non-assessable. Shareholders are not entitled to any appraisal rights with respect to their shares and, except as the Trustees may determine, shall have no preemptive, conversion, exchange or similar rights. The Fund may involuntarily redeem a shareholder’s shares upon certain conditions as may be determined by the Trustees, including, for example, if the shareholder fails to provide the Fund with identification required by law, or if the Fund is unable to verify the information received from the shareholder. Additionally, as discussed below, shares may be redeemed in connection with the closing of small accounts.

The Declaration specifically requires shareholders, upon demand, to disclose to the Fund such information with respect to their ownership of shares of the Fund, whether direct or indirect, as the Trustees may deem necessary in order to comply with various laws or regulations or for such other purpose as the Trustees may decide. The Fund may disclose such ownership information if required by law or regulation, or as the Trustees otherwise decide.

The Declaration provides that the Fund may close out a shareholder’s account by redeeming all of the shares in the account if the account falls below a minimum account size (which may vary by class) that may be set by the Trustees from time to time. Alternately, the Declaration permits the Fund to assess a fee for small accounts (which may vary by class) and redeem shares in the account to cover such fees, or convert the shares into another share class that is geared to smaller accounts.

The Declaration provides that the Trustees may establish series and classes in addition to those currently established and that the Trustees may determine the rights and preferences, limitations and restrictions, including qualifications for ownership, conversion and exchange features, minimum purchase and account size, expenses and charges, and other features of the series and classes. The Trustees may change any of those features, terminate any series or class, combine series with other series in the Trust, combine one or more classes of a series with another class in that series or convert the shares of one class into shares of another class.

Each share of the Fund, as a series of the Trust, represents an interest in the Fund only and not in the assets of any other series of the Trust.

The Declaration provides that shareholders are not personally liable for the obligations of the Fund and requires the Fund to indemnify a shareholder against any loss or expense claimed solely because of the shareholder’s being or having been a shareholder. The Fund will assume the defense of any claim against a shareholder for personal liability at the request of the shareholder. The Declaration further provides that a Trustee acting in his or her capacity as a Trustee is not personally liable to any person, other than the Trust or its shareholders, in connection with the affairs of the Trust. Each Trustee is required to perform his or her duties in good faith and in a manner he or she believes to be in the best interests of the Trust. All actions and omissions of Trustees are presumed to be in accordance with the foregoing standard of performance, and any person alleging the contrary has the burden of proving that allegation.

The Declaration limits a Trustee’s liability to the Trust or any shareholder to the fullest extent permitted under current Maryland law by providing that a Trustee is liable to the Trust or its shareholders for monetary damages only (a) to the extent that it is proved that he or she actually received an improper benefit or profit in money, property, or services or (b) to the extent that a judgment or other final adjudication adverse to the Trustee is entered in a proceeding based on a finding in the proceeding that the Trustee’s action, or failure to act, was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. The Declaration requires the Trust to indemnify any persons who are or who have been Trustees, officers or employees of the Trust to the fullest extent permitted by law against liability and expenses in connection with any claim or proceeding in which he or she is involved by virtue of having been a Trustee, officer or employee. Subject to applicable federal law, expenses related to the defense against any claim to which indemnification may apply shall be advanced by the Trust upon receipt of an undertaking by or on behalf of the recipient of those expenses to repay the advanced amount if it is ultimately found that he or she is not entitled to indemnification. In making any determination as to whether a person has engaged in conduct for which indemnification is not available, or as to whether there is reason to believe that such person ultimately will be found entitled to indemnification, such person shall be afforded a rebuttable presumption that he or she did not engage in conduct for which indemnification is not available.

The Declaration provides that any Trustee who serves as chair of the Board, a member or chair of a committee of the Board, lead independent Trustee, audit committee financial expert, or in any other similar capacity will not be subject to any greater standard of care or liability because of such position.

The Declaration provides a detailed process for the bringing of derivative actions by shareholders in order to permit legitimate inquiries and claims while avoiding the time, expense, distraction, and other harm that can be caused to the Fund or its shareholders as a result of spurious shareholder demands and derivative actions. Prior to bringing a derivative action, a demand by no fewer than three unrelated shareholders must be made on the Trustees. The Declaration details information, certifications, undertakings and acknowledgements that must be included in the demand. The Trustees are not required to consider a demand that is not submitted in accordance with the requirements contained in the Declaration. The Declaration also

requires that, in order to bring a derivative action, the complaining shareholders must be joined in the action by shareholders owning, at the time of the alleged wrongdoing, at the time of demand, and at the time the action is commenced, shares representing at least 5% of the voting power of the affected funds. The Trustees have a period of 90 days, which may be extended for an additional period not to exceed 60 days, to consider the demand. If a majority of the Trustees who are considered independent for the purposes of considering the demand determine that a suit should be maintained, then the Trust will commence the suit and the suit will proceed directly and not derivatively. If a majority of the independent Trustees determines that maintaining the suit would not be in the best interests of the Fund, the Trustees are required to reject the demand and the complaining shareholders may not proceed with the derivative action unless the shareholders are able to sustain the burden of proof to a court that the decision of the Trustees not to pursue the requested action was not consistent with the standard of performance required of the Trustees in performing their duties. If a demand is rejected, the complaining shareholders will be responsible for the costs and expenses (including attorneys’ fees) incurred by the Trust in connection with the consideration of the demand, if, in the judgment of the independent Trustees, the demand was made without reasonable cause or for an improper purpose. If a derivative action is brought in violation of the Declaration, the shareholders bringing the action may be responsible for the Fund’s costs, including attorneys’ fees.

The Declaration further provides that the Fund shall be responsible for payment of attorneys’ fees and legal expenses incurred by a complaining shareholder only if required by law, and any attorneys’ fees that the Fund is obligated to pay shall be calculated using reasonable hourly rates. The Declaration also requires that actions by shareholders against the Trust or the Fund be brought only in the U.S. District Court for the District of Maryland (Baltimore Division), or if such action may not be brought in that court, then such action shall be brought in the Circuit Court for Baltimore City and that the right to jury trial be waived to the fullest extent permitted by law.

The Declaration further provides that no provision of the Declaration will be effective to require a waiver of compliance with any provision of the 1933 Act, the 1934 Act or the 1940 Act, or of any valid rule, regulation or order of the Commission thereunder.

The Portfolio in which the Fund invests is a series of Master Portfolio Trust, a Maryland statutory trust, and is also governed by a declaration of trust similar to the Declaration. Whenever a vote is submitted to the Portfolio’s investors, the Fund will generally call a meeting of its own shareholders. To the extent it does not receive instructions from its shareholders, the Fund will vote its shares in the portfolio in the same proportion as the vote of shareholders who do give voting instructions. Alternatively, without seeking instructions from its shareholders, the Fund could vote its shares in the Portfolio in proportion to the vote of all the other investors in the Portfolio.

The following is a summary of certain material U.S. federal (and, where noted, state and local) income tax considerations affecting the Fund and its shareholders. This discussion is very general and does not address all the potential U.S. federal income tax consequences that may be applicable to the Fund or to all categories of investors, some of which may be subject to special tax rules. This summary is based upon the Code, its legislative history, Treasury regulations (including temporary and proposed regulations), published rulings, and court decisions, each as of the date of this SAI and all of which are subject to change, possibly with retroactive effect, which could affect the continuing accuracy of this discussion. This discussion assumes that each shareholder holds its shares of the Fund as capital assets for U.S. federal income tax purposes. Current and prospective shareholders are urged to consult their own tax advisers with respect to the specific federal, state, local, and foreign tax consequences of investing in the Fund.

Tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017. The Tax Act makes significant changes to the U.S. federal income tax rules for individuals and corporations, generally effective for taxable years beginning after December 31, 2017. Most of the changes applicable to individuals are temporary and, without further legislation, will not apply after 2025. The application of certain provisions of the Tax Act is uncertain, and the changes to the Code that the Tax Act enacted may have direct or indirect effects on the Fund, its investments, or its shareholders that cannot be predicted. In addition, legislative, regulatory, or administrative changes to, or in respect of the application of, the Tax Act could be enacted or promulgated at any time, either prospectively or with retroactive effect. Prospective investors should consult their tax advisers regarding the implications of the Tax Act on their investment in the Fund.

The Fund has elected to be treated, and intends to qualify each year, as a “regulated investment company” under Subchapter M of the Code. To qualify as such, the Fund must, among other things: (a) derive at least 90% of its gross income in each taxable year from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, other income (including, but not limited to, gains from options, futures, or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in “qualified publicly traded partnerships” (i.e., partnerships (x) the interests in which are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof, and (y) that derive less than 90% of their income from sources described in this subparagraph (a) other than qualified publicly traded partnerships); and (b) diversify its holdings so that, at the end of each quarter of the Fund’s taxable year, (i) at least 50% of the market value of the Fund’s assets consists of cash, securities of other regulated investment companies, U.S. government securities, and other securities, with such other securities limited, in respect of any one issuer, to an amount not greater than 5% of the value of the Fund’s assets and not more than 10% of the outstanding voting securities of such issuer and (ii) not more than 25% of the value of the Fund’s assets is invested, including through corporations in which the Fund owns a 20% or larger voting stock interest, (x) in the securities (other than U.S. government securities or securities of other regulated investment companies) of any one issuer, (y) in the securities (other than the securities of other regulated investment companies) of any two or more issuers that the Fund controls and that are treated as engaged in the same, similar, or related trades or businesses, or (z) in the securities of one or more “qualified publicly traded partnerships,” which generally include master limited partnerships.

In general, for purposes of the 90% gross income test described above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized directly by the Fund. However, 100% of the net income derived from an interest in a qualified publicly traded partnership will be treated as qualifying income. In general, qualified publicly traded partnerships will be treated as partnerships for U.S. federal income tax purposes because they meet a passive income requirement under the Code. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do apply to a regulated investment company with respect to items attributable to interests in qualified publicly traded partnerships. The Fund’s investments in partnerships, if any, including in qualified publicly traded partnerships, may result in the Fund being subject to state, local, or foreign income, franchise, or withholding tax liabilities.

For purposes of the diversification test described above, the term “outstanding voting securities of such issuer” will include the equity securities of a qualified publicly traded partnership. Also, for purposes of the diversification test, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In some cases, identification of the issuer (or issuers) is uncertain under current law, and an adverse determination or future guidance by the IRS with respect to issuer identification for a particular type of investment may adversely affect the Fund’s ability to meet the diversification test.

As a regulated investment company, the Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, the Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., generally, its taxable income other than the excess of its net long-term capital gain over its net short-term capital loss, plus or minus certain other adjustments, and calculated without regard to the deduction for dividends paid), and (ii) 90% of its net tax-exempt income for the taxable year. The Fund will be subject to income tax at regular corporate tax rates on any taxable income or gains that it does not distribute to its shareholders.

If, for any taxable year, the Fund were to fail to qualify as a regulated investment company under the Code or were to fail to meet the distribution requirement, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income. In addition, in the event of a failure to qualify, the Fund’s distributions, including any distributions of net tax-exempt income and net long-term capital gains, would be taxable to shareholders as ordinary dividend income for U.S. federal income tax purposes to the extent of the Fund’s current and accumulated earnings and profits. However, such dividends would be eligible, subject to any generally applicable limitations, (i) to be treated as qualified dividend income in the case of shareholders taxed as individuals and (ii) for the dividends-received deduction in the case of corporate shareholders. Moreover, if the Fund were to fail to qualify as a regulated investment company in any year, it would be required to pay out its earnings and profits accumulated in that year in order to qualify again as a regulated investment company. If the Fund were to fail to meet the income, diversification, or distribution test described above,

the Fund could in some cases cure such failure, including by paying Fund-level tax, paying interest, making additional distributions, or disposing of certain assets. In particular, if in the first instance, the Fund does not satisfy the diversification test as of a particular quarter end, it will have up to 30 days after that quarter end to adjust its holdings in order to comply with the test retroactively. Portfolio transactions executed by the Fund in order to comply with the diversification test will increase the Fund’s portfolio turnover and trading costs and may increase the amount of taxes payable by shareholders to the extent any capital gains are realized as a result of such transactions. If the Fund were to fail to qualify as a regulated investment company for a period greater than two taxable years, the Fund would generally be required to recognize any net built-in gains with respect to certain of its assets upon a disposition of such assets within five years of qualifying as a regulated investment company in a subsequent year.

If the Fund were to fail to distribute in a calendar year at least the sum of (i) 98% of its ordinary income for that year and (ii) 98.2% of its capital gain net income (i.e., the excess of all gains from sales or exchanges of capital assets over the losses from such sales or exchanges) for the one-year period ending October 31 of that year (or November 30 or December 31 of that year if the Fund is permitted to elect and so elects) it would be subject to a 4% nondeductible excise tax. For this purpose, however, any ordinary income or capital gain net income that is retained by the Fund and subject to corporate income tax will be considered to have been distributed by year end. In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. For purposes of the required excise tax distribution, a regulated investment company’s ordinary gains and losses from the sale, exchange or other taxable disposition of property that would otherwise be taken into account after October 31 of a calendar year (or November 30 of that year if the regulated investment company makes the election described above) generally are treated as arising on January 1 of the following calendar year; in the case of a Fund with a December 31 year end that makes the election described above, no such gains or losses will be so treated. The Fund anticipates that it will pay such dividends and will make such distributions as are necessary to avoid the application of this excise tax, but there can be no assurance that it will be able to do so. In determining its net capital gain (i.e., net realized long-term capital gains in excess of net realized short-term capital losses, including any capital loss carryforwards), its taxable income, and its earnings and profits, a regulated investment company generally is permitted to elect to treat part or all of any post-October capital loss (defined as any net capital loss attributable to the portion of the taxable year after October 31, or if there is no such loss, the net long-term capital loss or net short-term capital loss attributable to such portion of the taxable year), or late-year ordinary loss (generally, the sum of its (i) net ordinary loss from the sale, exchange or other taxable disposition of property, attributable to the portion of the taxable year after October 31 and its (ii) other net ordinary loss attributable to the portion of the taxable year after December 31) as if incurred in the succeeding taxable year.

The Fund’s transactions in zero coupon securities, foreign currencies, forward contracts, options, and futures contracts (including options and futures contracts on foreign currencies), if any, will be subject to special provisions of the Code (including provisions relating to “hedging transactions” and “straddles”) that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund, and defer Fund losses. These rules could therefore affect the character, amount, and timing of distributions to shareholders. These provisions also (a) will require the Fund to “mark to market” certain types of the positions in its portfolio (i.e., require the Fund to treat all unrealized gains and losses with respect to those positions as though they were realized at the end of each year) and (b) may cause the Fund to recognize income prior to or without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. In order to distribute this income and avoid a tax at the Fund level, the Fund might be required to sell portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss.

As a result of entering into swap contracts, if any, the Fund may make or receive periodic net payments. The Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). With respect to certain types of swaps, the Fund may be required to recognize currently income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Any investments by the Fund in so-called “section 1256 contracts,” such as regulated futures contracts, most foreign currency forward contracts traded in the interbank market, and options on most stock indexes, are subject to special tax rules. Any section 1256 contracts held by the Fund at the end of its taxable year (and, for purposes of the 4% excise tax, on certain later dates as prescribed under the Code) are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Fund from positions in section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were neither part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Fund.

In general, option premiums received by the Fund are not immediately included in the income of the Fund. Instead, the premiums are recognized when the option contract expires, the option is exercised by the holder, or the Fund transfers or otherwise terminates the option (e.g., through a closing transaction). If a call option written by the Fund is exercised and the Fund sells or delivers the underlying security, the Fund generally will recognize capital gain or loss equal to (a) sum of the strike price and the option premium received by the Fund minus (b) the Fund’s basis in the security. Such gain or loss generally will be short-term or long-term depending upon the holding period of the underlying security. If securities are purchased by the Fund pursuant to the exercise of a put option written by it, the Fund generally will subtract the premium received for purposes of computing its cost basis in the securities purchased. Gain or loss arising in respect of a termination of the Fund’s obligation under an option other than through the exercise of the option will be short-term gain or loss depending on whether the premium income received by the Fund is greater or less than the amount paid by the Fund (if any) in terminating the transaction. Thus, for example, if an option written by the Fund expires unexercised, the Fund generally will recognize short-term gain equal to the premium received.

In general, gain or loss on a short sale is recognized when the Fund closes the sale by delivering the borrowed property to the lender, not when the borrowed property is sold. Gain or loss from a short sale is generally considered as capital gain or loss to the extent that the property used to close the short sale constitutes a capital asset in the Fund’s hands. Except with respect to certain situations where the property used by the Fund to close a short sale has a long-term holding period on the date of the short sale, special rules generally treat the gains on short sales as short-term capital gains. These rules may also terminate the running of the holding period of “substantially identical property” held by the Fund. Moreover, a loss on a short sale will be treated as a long-term capital loss if, on the date of the short sale, “substantially identical property” has been held by the Fund for more than one year. In general, the Fund will not be permitted to deduct payments made to reimburse the lender of securities for dividends paid on borrowed stock if the short sale is closed on or before the 45th day after the short sale is entered into.

The Fund may purchase debt obligations with original issue discount (“OID”), market discount, or acquisition discount. Some debt obligations with a fixed maturity date of more than one year from the date of issuance (and all zero-coupon debt obligations with a fixed maturity date of more than one year from the date of issuance) will be treated as debt obligations that are issued with OID. Generally, the amount of the OID is treated as interest income and is included in taxable income (and is accordingly required to be distributed by the Fund) over the term of the debt security, even though payment of that amount is not received until a later time, usually when the debt security matures. Periodic adjustments for inflation in the principal value of inflation-indexed bonds also may be treated as OID that is includible in the Fund’s gross income on a current basis.

Some debt obligations with a fixed maturity date of more than one year from the date of issuance in the secondary market may be treated as having “market discount.” Very generally, market discount is the excess of the stated redemption price of a debt obligation (or in the case of an obligation issued with OID, its “revised issue price”) over the purchase price of such obligation. Under the Code, (i) generally, any gain recognized on the disposition of, and any partial payment of principal on, a debt security having market discount is treated as ordinary income to the extent the gain, or principal payment, does not exceed the “accrued market discount” on such debt security, (ii) alternatively, the Fund may elect to accrue market discount currently, in which case the Fund will be required to include the accrued market discount in the Fund’s income (as ordinary income) and thus distribute it over the term of the debt security, even though payment of that amount is not received until a later time, upon partial of full repayment or disposition of the debt security, and (iii) the rate at which the market discount accrues, and thus is included in the Fund’s income, will depend upon which of the permitted accrual methods the Fund elects.

Some debt obligations with a fixed maturity date of one year or less from the date of issuance that are acquired by the Fund may be treated as having OID or, in certain cases, “acquisition discount” (very generally, the excess of the stated redemption price over the purchase price). The Fund will be required to include the OID or acquisition discount in income (as ordinary income) and thus distribute it over the term of the debt security, even though payment of that amount is not received until a later time, upon partial or full repayment or disposition of the debt security. The rate at which OID or acquisition discount accrues, and thus is included in the Fund’s income, will depend upon which of the permitted accrual methods the Fund elects.

Because the OID, market discount, or acquisition discount earned by the Fund in a taxable year may exceed the total amount of cash interest the Fund receives from the relevant debt obligations, the Fund may have to dispose of one or more of its investments, including at a time when it is not advantageous to do so, and use the proceeds thereof to make distributions in amounts necessary to satisfy the distribution requirements. The Fund may realize capital gains or losses from such dispositions, which would increase or decrease the Fund’s investment company taxable income and/or net capital gain.

In addition, payment-in-kind securities held by the Fund, if any, will give rise to income which is required to be distributed and is taxable even though the Fund receives no interest payment in cash on the security during the year.

Very generally, where the Fund purchases a bond at a price that exceeds the redemption price at maturity (i.e., a premium), the premium is amortizable over the remaining term of the bond. In the case of a taxable bond, if the Fund makes an election applicable to all such bonds it purchases, which election is irrevocable without consent of the IRS, the Fund reduces the current taxable income from the bond by the amortized premium and reduces its tax basis in the bond by the amount of such offset; upon the disposition or maturity of such bonds acquired on or after January 4, 2013, the Fund is permitted to deduct any remaining premium allocable to a prior period. In the case of a tax-exempt bond, tax rules require the Fund to reduce its tax basis by the amount of amortized premium.

The Fund may invest in debt obligations that are in the lowest rating categories or are unrated, including debt obligations of issuers not currently paying interest or that are in default. Investments in debt obligations that are at risk of or in default present special tax issues for the Fund. Tax rules are not entirely clear about issues such as when the Fund may cease to accrue interest, OID or market discount, when and to what extent deductions may be taken for bad debts or worthless securities, and how payments received on obligations in default should be allocated between principal and income. These and other related issues will be addressed by the Fund when, as, and if it invests in such securities, in order to seek to ensure that it distributes sufficient income to preserve its eligibility for treatment as a regulated investment company and does not become subject to U.S. federal income or excise tax.

A portion of the interest paid or accrued on high yield obligations may not (and interest paid on debt obligations, if any, that are considered for tax purposes to be payable in the equity of the issuer or a related party will not) be deductible to the issuer. If a portion of the interest paid or accrued on certain high yield discount obligations is not deductible by the issuer, that portion will be treated as a dividend for purposes of the corporate dividends-received deduction. In such cases, if the issuer of the high yield discount obligations is a domestic corporation, dividend payments by the Fund may be eligible for the dividends-received deduction to the extent of the deemed dividend portion of such accrued interest.

The Fund may be required to treat amounts as taxable income or gain, subject to the distribution requirements referred to above, even though no corresponding amounts of cash are received concurrently, as a result of (1) mark-to-market rules, constructive sale rules or rules applicable to PFICs (as defined below), to partnerships or trusts in which the Fund invests or to certain options, futures, or forward contracts, or “appreciated financial positions,” (2) the inability to obtain cash distributions or other amounts due to currency controls or restrictions on repatriation imposed by a foreign country with respect to the Fund’s investments (including through depositary receipts) in issuers in such country, or (3) tax rules applicable to debt obligations acquired with OID, including zero-coupon or deferred payment bonds and pay-in-kind debt obligations, or to market discount if the Fund elects to accrue such market discount currently. In order to distribute this income and avoid a tax on the Fund, the Fund might be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss. The Fund might also meet the distribution requirements by borrowing the necessary cash, thereby incurring interest expenses.

Dividends, interest or other income (including, in some cases, capital gains) received by the Fund from investments in foreign securities may be subject to withholding and other taxes imposed by foreign countries. Even if the Fund is entitled to seek

a refund in respect of such taxes, it may choose not to. Tax conventions between certain countries and the United States may reduce or eliminate such taxes in some cases. If more than 50% of the value of the Fund’s assets at the close of any taxable year consists of stock or securities of foreign corporations, which for this purpose may include obligations of foreign governmental issuers, the Fund may elect, for U.S. federal income tax purposes, to treat foreign income or withholding taxes paid by the Fund, if any, as paid by its shareholders. For any year that the Fund is eligible for and makes such an election, each shareholder of the Fund will be required to include in income an amount equal to his or her allocable share of qualified foreign income taxes paid by the Fund, and shareholders will be entitled, subject to certain holding period requirements and other limitations, to credit their portions of these amounts against their United States federal income tax due, if any, or to deduct their portions from their United States taxable income, if any. No deductions for foreign taxes paid by the Fund may be claimed, however, by non-corporate shareholders who do not itemize deductions and no deductions for foreign taxes will be permitted to individuals in computing their alternative minimum tax liability. Even if the Fund qualifies to make this election, it may choose not to do so; in that case, foreign taxes that the Fund pays will nonetheless reduce the Fund’s taxable income. Foreign taxes paid by the Fund may reduce the return from the Fund’s investments.

Under certain circumstances, if the Fund receives a refund of foreign taxes paid in respect of a prior year, the value of Fund shares could be affected or any foreign tax credits or deductions passed through to shareholders in respect of the Fund’s foreign taxes for the current year could be reduced.

Under Section 988 of the Code, gains or losses attributable to fluctuations in exchange rates between the time the Fund accrues income or receivables or expenses or other liabilities denominated in a foreign currency and the time the Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. Similarly, gains or losses on foreign currency, foreign currency forward contracts, certain foreign currency options or futures contracts and the disposition of debt securities denominated in foreign currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless the Fund were to elect otherwise.

Passive Foreign Investment Companies. If the Fund purchases equity interests (including certain interests treated as equity interests) in foreign entities treated as “passive foreign investment companies” (“PFICs”) for U.S. federal income tax purposes, and does not timely make certain elections, it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on the Fund in respect of deferred taxes arising from such distributions or gains.

In general, a PFIC is any foreign corporation in which (i) 75% or more of the gross income for the taxable year is passive income, or (ii) the average percentage of the assets (generally by value, but by adjusted tax basis in certain cases) that produce, or are held for the production of, passive income is at least 50%. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gains over losses from certain property transactions and commodities transactions, income from certain notional principal contracts, and foreign currency gains. Passive income for this purpose does not include certain types of passive income excepted by the Code and other guidance.

If the Fund were to invest in a PFIC and timely elect to treat the PFIC as a “qualified electing fund” under the Code for the first year of its holding period in the PFIC stock, in lieu of the foregoing requirements, the Fund would generally be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to the Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to distribute this income and avoid a tax at the Fund level, the Fund might be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss. In order to make the “qualified electing fund” election, the Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain. Dividends paid by PFICs will not be eligible to be treated as “qualified dividend income.”

If the Fund were to invest in a PFIC and make a mark-to-market election, the Fund would be treated as if it had sold and repurchased its stock in that PFIC at the end of each year. In such case, the Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. Such an election must be made separately for each PFIC owned by the Fund and, once made, would be effective for all subsequent taxable years of the Fund, unless revoked with the consent of the IRS. By making the election, the Fund could potentially ameliorate the adverse tax

consequences with respect to its ownership of shares in a PFIC, but in any particular year might be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. The Fund might have to distribute such excess income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax. In order to distribute this income and avoid a tax at the Fund level, the Fund might be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss.

Dividends and Distributions. Dividends and other distributions by the Fund are generally treated under the Code as received by the shareholders at the time the dividend or distribution is made. However, if any dividend or distribution is declared by the Fund in October, November, or December of any calendar year and payable to shareholders of record on a specified date in such a month but is actually paid during the following January, such dividend or distribution will be deemed to have been received by each shareholder on December 31 of the year in which the dividend was declared.

The Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income (determined without regard to the dividends-received deduction), and any net capital gain. However, if the Fund retains for investment an amount equal to all or a portion of its net capital gain, it will be subject to a corporate tax on the amount retained. In that event, the Fund may designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the income tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to their share of the excess of the amount of undistributed net capital gain included in their income over the income paid by the Fund on the undistributed amount. Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon timely filing appropriate returns or claims for refund with the IRS.

Distributions of net investment income and of net realized short-term capital gains, whether paid in cash or in shares, are taxable to a U.S. shareholder as ordinary income or, if certain conditions are met, as “qualified dividend income,” taxable to individual and certain other non-corporate shareholders at the rates applicable to long-term capital gain. Distributions of net capital gain, if any, that the Fund reports as capital gain dividends are taxable as long-term capital gains, whether paid in cash or in shares, and regardless of how long a shareholder has held shares of the Fund.

In general, dividends may be reported by the Fund as qualified dividend income if they are attributable to qualified dividend income received by the Fund. Qualified dividend income generally means dividend income received from the Fund’s investments in common and preferred stock of U.S. corporations and stock of certain qualified foreign corporations, provided that certain holding period and other requirements are met by both the Fund and the shareholders. If 95% or more of the Fund’s gross income (calculated without taking into account net capital gain derived from sales or other dispositions of stock or securities) consists of qualified dividend income, the Fund may report all distributions of such income as qualified dividend income.

A foreign corporation is treated as a qualified foreign corporation for this purpose if it is incorporated in a possession of the United States or it is eligible for the benefits of certain income tax treaties with the United States and meets certain additional requirements. Certain foreign corporations that are not otherwise qualified foreign corporations will be treated as qualified foreign corporations with respect to dividends paid by them if the stock with respect to which the dividends are paid is readily tradable on an established securities market in the United States. PFICs are not qualified foreign corporations for this purpose.

A dividend that is attributable to qualified dividend income of the Fund that is paid by the Fund to a shareholder will not be taxable as qualified dividend income to such shareholder (1) if the dividend is received with respect to any share of the Fund held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share became ex-dividend with respect to such dividend, (2) to the extent that the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related

property, or (3) if the shareholder elects to have the dividend treated as investment income for purposes of the limitation on deductibility of investment interest. The “ex-dividend” date is the date on which the owner of the share at the commencement of such date is entitled to receive the next issued dividend payment for such share even if the share is sold by the owner on that date or thereafter.

Certain dividends received by the Fund from U.S. corporations (generally, dividends received by the Fund in respect of any share of stock (1) with a tax holding period of at least 46 days during the 91-day period beginning on the date that is 45 days before the date on which the stock becomes ex-dividend as to that dividend and (2) that is held in an unleveraged position) and distributed and appropriately so reported by the Fund may be eligible for the dividends-received deduction generally available to corporations under the Code. Certain preferred stock must have a holding period of at least 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend as to that dividend in order to be eligible. Capital gain dividends distributed to the Fund from other regulated investment companies are not eligible for the dividends-received deduction. In order to qualify for the deduction, corporate shareholders must meet the minimum holding period requirement stated above with respect to their Fund shares, taking into account any holding period reductions from certain hedging or other transactions or positions that diminish their risk of loss with respect to their Fund shares, and, if they borrow to acquire or otherwise incur debt attributable to Fund shares, they may be denied a portion of the dividends-received deduction with respect to those shares. Any corporate shareholder should consult its tax adviser regarding the possibility that its tax basis in its shares may be reduced, for U.S. federal income tax purposes, by reason of “extraordinary dividends” received with respect to the shares and, to the extent such basis would be reduced below zero, current recognition of income may be required.

The Fund does not anticipate that any of its dividends paid will qualify for the dividends-received deduction or be treated as qualified dividend income. The Fund expects that it generally will not earn or distribute any long-term capital gains.

Dividends and distributions from the Fund will generally be taken into account in determining a shareholder’s “net investment income” for purposes of the Medicare contribution tax applicable to certain individuals, estates and trusts.

Certain tax-exempt educational institutions will be subject to a 1.4% tax on net investment income. For these purposes, certain dividends and capital gain distributions, and certain gains from the disposition of Fund shares (among other categories of income), are generally taken into account in computing a shareholder’s net investment income.

Distributions in excess of the Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of the shareholder’s basis in his or her shares of the Fund, and as a capital gain thereafter (if the shareholder holds his or her shares of the Fund as capital assets). One or more of the Fund’s distributions during the year may include such a return of capital distribution. Each shareholder who receives distributions in the form of additional shares will be treated for U.S. federal income tax purposes as if receiving a distribution in an amount equal to the amount of money that the shareholder would have received if he or she had instead elected to receive cash distributions. The shareholder’s aggregate tax basis in shares of the Fund will be increased by such amount.

Investors considering buying shares just prior to a capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such distribution may nevertheless be taxable to them.

If Fund shares are held through a qualified retirement plan entitled to tax-advantaged treatment for federal income tax purposes, distributions will generally not be taxable currently. Special tax rules apply to such retirement plans. You should consult your tax adviser regarding the tax treatment of distributions (which may include amounts attributable to Fund distributions) which may be taxable when distributed from the retirement plan.

Sale, Exchange, or Redemption of Shares. Upon the sale or exchange of his or her shares, a shareholder will generally recognize a taxable gain or loss equal to the difference between the amount realized and his or her basis in those shares. A redemption of shares will be treated as a sale for this purpose. However, a shareholder will generally not have any gain or loss on the sale or exchange so long as the Fund maintains a stable net asset value of $1.00 per share and does not impose a liquidity fee.

There is uncertainty with respect to the tax treatment of liquidity fees received by the Fund. The tax treatment of liquidity fees may be the subject of future guidance issued by the IRS. If the Fund maintains a stable net asset value of $1.00 per share, the imposition of a liquidity fee on a shareholder’s redemption of shares is generally expected to cause the shareholder to

recognize a loss. If the Fund does not maintain a stable net asset value of $1.00 per share, the imposition of a liquidity fee on a redemption of Fund shares could cause the shareholder to recognize a loss or could decrease the gain or increase the loss the shareholder would otherwise recognize. Although there is no definitive guidance, any liquidity fees received by the Fund may result in distributions or gains that would be taxable to the Fund’s shareholders. Any gain or loss recognized on a redemption of Fund shares will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands.

For shareholders not electing the “NAV method” described below, any capital gain or loss will generally be long-term capital gain or loss if the shareholder held such shares for more than one year and short-term capital gain or loss if the shareholder held such shares for one year or less. For shareholders in a fund that attempts to maintain a stable NAV of $1.00 per share who have not elected the NAV method, any loss realized on a sale or exchange will be disallowed to the extent the shares are replaced, including replacement through the reinvesting of dividends and capital gains distributions in the fund, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss.

A shareholder may elect the “NAV method” for computing gains and losses from redemptions and exchanges. Under the NAV method, rather than computing gain or loss separately for each taxable disposition of Fund shares, an electing shareholder determines gain or loss on an aggregate basis for each “computation period” (which could be a taxable year or certain shorter periods within a taxable year). Gain or loss under the NAV method is based on the change in the aggregate value of the electing shareholder’s shares during the applicable period (or, for the first period in which the NAV method applies, the difference between the aggregate value at the end of the period and the adjusted tax basis at the beginning of the period), reduced by the shareholder’s purchases of Fund shares (including purchases through reinvestment of dividends) and increased by the proceeds of redemptions of Fund shares during that period. If a shareholder holds shares as a capital asset, any resulting net gain or loss is treated as short-term capital gain or loss. The NAV method election is generally made by a shareholder on a fund-by-fund basis. Additionally, if a shareholder holds the Fund’s shares in more than one account, the shareholder is required to treat each account as a separate fund for purposes of these rules. For shares in a fund that maintains a stable net asset value of $1.00 per share and that does not impose a liquidity fee, it is possible that there will not be a benefit to the shareholder to electing the NAV method. Shareholders should consult their tax advisers about the NAV method.

Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder (including amounts credited to the shareholder as undistributed capital gains) with respect to such shares.

If a shareholder recognizes a loss with respect to the Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder (or certain greater amounts over a combination of years), the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. The fact that a loss is so reportable does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper.

If a shareholder’s shares are redeemed to pay a fee because the shareholder’s account balance is less than a certain threshold, the redemption will be treated as a taxable sale or exchange of shares, as described above. Such a fee generally will not be deductible by a shareholder that is an individual for any taxable year beginning after December 31, 2017 and before January 1, 2026, and, for other taxable years, the deductibility of such a fee by a shareholder that is an individual may be subject to generally applicable limitations on miscellaneous itemized deductions.

Backup Withholding. The Fund may be required in certain circumstances to apply backup withholding on dividends and other distributions payable to non-corporate shareholders who fail to provide the Fund with their correct taxpayer identification numbers or to make required certifications, or who have been notified by the IRS that they are subject to backup withholding. Certain shareholders are exempt from backup withholding. Backup withholding is not an additional tax and any amount withheld may be credited against a shareholder’s U.S. federal income tax liability.

Notices. Shareholders will receive, if appropriate, various written notices after the close of the Fund’s taxable year regarding the U.S. federal income tax status of certain dividends, distributions and redemption proceeds that were paid (or that are treated as having been paid) by the Fund to its shareholders during the preceding taxable year. In certain cases, the Fund may

be required to amend the tax information reported to you with respect to a particular year. In this event, you may be required to file amended U.S. federal income or other tax returns with respect to such amended information and, if applicable, to pay additional taxes (including potentially interest and penalties) or to seek a tax refund and may incur other related costs.

Dividends, distributions and redemption proceeds may also be subject to additional state, local and foreign taxes depending on each shareholder’s particular situation. Generally, shareholders will have to pay state or local taxes on Fund dividends and other distributions, although distributions derived from interest on U.S. government obligations (but not distributions of gain from the sale of such obligations) may be exempt from certain state and local taxes.

Ordinary dividends and certain other payments made by the Fund to non-U.S. shareholders are generally subject to federal withholding tax at a 30% rate (or such lower rate as may be determined in accordance with any applicable treaty). In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN or similar form certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides an IRS Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the United States. Instead, the effectively connected dividends will be subject to regular U.S. federal income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or a lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN or other applicable form may be subject to backup withholding at the appropriate rate. Backup withholding will not be applied to payments that have already been subject to the 30% withholding tax.

The 30% withholding tax generally will not apply to distributions of the excess of net long-term capital gains over net short-term capital losses or to redemption proceeds. The 30% withholding tax also will not apply to dividends that the Fund reports as (a) interest-related dividends, to the extent such dividends are derived from the Fund’s “qualified net interest income,” or (b) short-term capital gain dividends, to the extent such dividends are derived from the Fund’s “qualified short-term gain.” “Qualified net interest income” is the Fund’s net income derived from U.S.-source interest and OID, subject to certain exceptions and limitations. “Qualified short-term gain” generally means the excess of the net short-term capital gain of the Fund for the taxable year over its net long-term capital loss, if any. In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports a payment as an interest-related dividend or a short-term capital gain dividend. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

A non-U.S. shareholder is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund unless (i) such gain is effectively connected with the conduct of a trade or business carried on by the non-U.S. shareholder within the United States, (ii) in the case of a non-U.S. shareholder that is an individual, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale and certain other conditions are met or (iii) the special rules relating to gain attributable to the sale or exchange of “United States real property interests” (as defined below, “USRPIs”) apply to the non-U.S. shareholder’s sale of shares of the Fund.

Special rules would apply if the Fund were a qualified investment entity (“QIE”) because it is either a “United States real property holding corporation” (“USRPHC”) or would be a USRPHC but for the operation of certain exceptions to the definition of USRPIs described below. Very generally, a USRPHC is a domestic corporation that holds USRPIs the fair market value of which equals or exceeds 50% of the sum of the fair market values of the corporation’s USRPIs, interests in real property located outside the United States, and other trade or business assets. USRPIs are generally defined as any interest in U.S. real property and any interest (other than solely as a creditor) in a USRPHC or, very generally, an entity that has been a USRPHC in the last five years. A regulated investment company that holds, directly or indirectly, significant interests in REITs may be a USRPHC. Interests in domestically controlled QIEs, including REITs and regulated investment companies that are QIEs, not-greater-than-10% interests in publicly traded classes of stock in REITs and not-greater-than-5% interests in publicly traded classes of stock in regulated investment companies generally are not USRPIs, but these exceptions do not apply for purposes of determining whether the Fund is a QIE. If an interest in the Fund were a USRPI, the Fund would be required to withhold U.S. tax on the proceeds of a share redemption by a greater-than-5% non-U.S. shareholder, in which case such non-U.S. shareholder generally would also be required to file U.S. federal income tax returns and pay any additional taxes due in connection with the redemption.

If the Fund were a QIE, under a special “look through” rule, any distributions by the Fund to a non-U.S. shareholder (including, in certain cases, distributions made by the Fund in redemption of its shares) attributable directly or indirectly to (i) distributions received by the Fund from a lower-tier regulated investment company or REIT that the Fund is required to treat as USRPI gain in its hands and (ii) gains realized on the disposition of USRPIs by the Fund would retain their character as gains realized from USRPIs in the hands of the Fund’s non-U.S. shareholders and would be subject to U.S. tax withholding. In addition, such distributions could result in the non-U.S. shareholder being required to file a U.S. federal income tax return and pay tax on the distributions at regular U.S. federal income tax rates. The consequences to a non-U.S. shareholder, including the rate of such withholding and character of such distributions (e.g., as ordinary income or USRPI gain), would vary depending upon the extent of the non-U.S. shareholder’s current and past ownership of the Fund.

Under legislation commonly known as “FATCA,” the Fund is required to withhold 30% of certain ordinary dividends it pays to shareholders that fail to meet prescribed information reporting or certification requirements. In general, no such withholding will be required with respect to a U.S. person or non-U.S. individual that timely provides the certifications required by the Fund or its agent on a valid IRS Form W-9 or applicable IRS Form W-8, respectively. Shareholders potentially subject to withholding include foreign financial institutions (“FFIs”), such as non-U.S. investment funds, and non-financial foreign entities (“NFFEs”). To avoid withholding under FATCA, an FFI generally must enter into an information sharing agreement with the IRS in which it agrees to report certain identifying information (including name, address, and taxpayer identification number) with respect to its U.S. account holders (which, in the case of an entity shareholder, may include its direct and indirect U.S. owners), and an NFFE generally must identify and provide other required information to the Fund or other withholding agent regarding its U.S. owners, if any. Such non-U.S. shareholders also may fall into certain exempt, excepted or deemed compliant categories as established by regulations and other guidance. A non-U.S. shareholder in a country that has entered into an intergovernmental agreement with the U.S. to implement FATCA will be exempt from FATCA withholding provided that the shareholder and the applicable foreign government comply with the terms of such agreement.

A non-U.S. entity that invests in the Fund will need to provide the Fund with documentation properly certifying the entity’s status under FATCA in order to avoid FATCA withholding.

Non-U.S. investors should consult their own tax advisers regarding the impact of these requirements on their investment in the Fund.

Generally, dividends received from a fund that are attributable to interest on U.S. government securities are not subject to state and local income taxes.

Pursuant to Rule 17j-1 under the 1940 Act, the Fund, the Manager, the Subadviser and the Distributor each has adopted a code of ethics that permits its personnel to invest in securities for their own accounts, including securities that may be purchased or held by the Fund. All personal securities transactions by employees must adhere to the requirements of the codes of ethics. Copies of the codes of ethics applicable to personnel of the Fund, the Manager, the Subadviser, the Distributor and the Independent Trustees are on file with the SEC.

There are no financial statements for the Fund because the Fund is newly offered.

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) delegates to each sub-adviser the responsibility for voting proxies for its funds, as applicable, to each sub-adviser through its contracts with each sub-adviser. Each sub-adviser may use its own proxy voting policies and procedures to vote proxies of the funds if the funds’ Board reviews and approves the use of those policies and procedures. Accordingly, LMPFA does not expect to have proxy-voting responsibility for any of the funds.

Should LMPFA become responsible for voting proxies for any reason, such as the inability of a sub-adviser to provide investment advisory services, LMPFA shall utilize the proxy voting guidelines established by the most recent sub-adviser to vote proxies until a new sub-adviser is retained and the use of its proxy voting policies and procedures is authorized by the Board. In the case of a material conflict between the interests of LMPFA (or its affiliates if such conflict is known to persons responsible for voting at LMPFA) and any fund, the Board of Directors of LMPFA shall consider how to address the conflict and/or how to vote the proxies. LMPFA shall maintain records of all proxy votes in accordance with applicable securities laws and regulations.

LMPFA shall be responsible for gathering relevant documents and records related to proxy voting from each sub-adviser and providing them to the funds as required for the funds to comply with applicable rules under the Investment Company Act of 1940. LMPFA shall also be responsible for coordinating the provision of information to the Board with regard to the proxy voting policies and procedures of each sub-adviser, including the actual proxy voting policies and procedures of each sub-adviser, changes to such policies and procedures, and reports on the administration of such policies and procedures.

An investment adviser is required to adopt and implement policies and procedures that we believe are reasonably designed to ensure that proxies are voted in the best interest of clients, in accordance with fiduciary duties and SEC Rule 206(4)-6 under the Investment Advisers Act of 1940 (“Advisers Act”). The authority to vote the proxies of our clients is established through investment management agreements or comparable documents. In addition to SEC requirements governing advisers, long-standing fiduciary standards and responsibilities have been established for ERISA accounts. Unless a manager of ERISA assets has been expressly precluded from voting proxies, the Department of Labor has determined that the responsibility for these votes lies with the investment manager.

As a fixed income only manager, the occasion to vote proxies is very rare. However, the Firm has adopted and implemented policies and procedures that we believe are reasonably designed to ensure that proxies are voted in the best interest of clients, in accordance with our fiduciary duties and SEC Rule 206(4)- 6 under the Investment Advisers Act of 1940 (“Advisers Act”). In addition to SEC requirements governing advisers, our proxy voting policies reflect the long-standing fiduciary standards and responsibilities for ERISA accounts. Unless a manager of ERISA assets has been expressly precluded from voting proxies, the Department of Labor has determined that the responsibility for these votes lies with the Investment Manager.

While the guidelines included in the procedures are intended to provide a benchmark for voting standards, each vote is ultimately cast on a case-by-case basis, taking into consideration the Firm’s contractual obligations to our clients and all other relevant facts and circumstances at the time of the vote (such that these guidelines may be overridden to the extent the Firm deems appropriate).

In exercising its voting authority, Western Asset will not consult or enter into agreements with officers, directors or employees of Legg Mason Inc. or any of its affiliates (other than Western Asset affiliated companies) regarding the voting of any securities owned by its clients.

The Western Asset Legal and Compliance Department (“Compliance Department”) is responsible for administering and overseeing the proxy voting process. The gathering of proxies is coordinated through the Corporate Actions area of Investment Support (“Corporate Actions”). Research analysts and portfolio managers are responsible for determining appropriate voting positions on each proxy utilizing any applicable guidelines contained in these procedures.

The Investment Management Agreement for each client is reviewed at account start-up for proxy voting instructions. If an agreement is silent on proxy voting, but contains an overall delegation of discretionary authority or if the account represents assets of an ERISA plan, Western Asset will assume responsibility for proxy voting. The Legal and Compliance Department maintains a matrix of proxy voting authority.

Registered owners of record, client custodians, client banks and trustees (“Proxy Recipients”) that receive proxy materials on behalf of clients should forward them to Corporate Actions. Proxy Recipients for new clients (or, if Western Asset becomes aware that the applicable Proxy Recipient for an existing client has changed, the Proxy Recipient for the existing client) are notified at start-up of appropriate routing to Corporate Actions of proxy materials received and reminded of their responsibility to forward all proxy materials on a timely basis. If Western Asset personnel other than Corporate Actions receive proxy materials, they should promptly forward the materials to Corporate Actions.

Once proxy materials are received by Corporate Actions, they are forwarded to the Legal and Compliance Department for coordination and the following actions:

Western Asset personnel act in such a manner to ensure that, absent special circumstances, the proxy gathering, and proxy voting steps noted above can be completed before the applicable deadline for returning proxy votes.

Western Asset maintains records of proxies voted pursuant to Section 204-2 of the Advisers Act and ERISA DOL Bulletin 94-2. These records include:

Records are maintained in an easily accessible place for five years, the first two in Western Asset’s offices.

Western Asset’s proxy policies are described in the firm’s Part 2A of Form ADV. Clients will be provided a copy of these policies and procedures upon request. In addition, upon request, clients may receive reports on how their proxies have been voted.

All proxies are reviewed by the Legal and Compliance Department for material conflicts of interest.

Western Asset’s substantive voting decisions turn on the particular facts and circumstances of each proxy vote and are evaluated by the designated research analyst or portfolio manager. The examples outlined below are meant as guidelines to aid in the decision making process.

Guidelines are grouped according to the types of proposals generally presented to shareholders. Part I deals with proposals which have been approved and are recommended by a company’s board of directors; Part II deals with proposals submitted by shareholders for inclusion in proxy statements; Part III addresses issues relating to voting shares of investment companies; and Part IV addresses unique considerations pertaining to foreign issuers.

The vast majority of matters presented to shareholders for a vote involve proposals made by a company itself that have been approved and recommended by its board of directors. In view of the enhanced corporate governance practices currently being implemented in public companies, Western Asset generally votes in support of decisions reached by independent boards of directors. More specific guidelines related to certain board-approved proposals are as follows:

Western Asset votes proxies for the election of the company’s nominees for directors and for board- approved proposals on other matters relating to the board of directors with the following exceptions:

Western Asset generally favors compensation programs that relate executive compensation to a company’s long-term performance. Votes are cast on a case-by-case basis on board-approved proposals relating to executive compensation, except as follows:

The management of a company’s capital structure involves a number of important issues, including cash flows, financing needs and market conditions that are unique to the circumstances of each company. As a result, Western Asset votes on a case-by-case basis on board-approved proposals involving changes to a company’s capitalization except where Western Asset is otherwise withholding votes for the entire board of directors.

Western Asset votes these issues on a case-by-case basis on board-approved transactions.

Western Asset votes against board-approved proposals to adopt anti-takeover measures except as follows:

Western Asset votes for board-approved proposals approving such routine business matters such as changing the company’s name, ratifying the appointment of auditors and procedural matters relating to the shareholder meeting.

SEC regulations permit shareholders to submit proposals for inclusion in a company’s proxy statement. These proposals generally seek to change some aspect of a company’s corporate governance structure or to change some aspect of its business operations. Western Asset votes in accordance with the recommendation of the company’s board of directors on all shareholder proposals, except as follows:

Western Asset may utilize shares of open or closed-end investment companies to implement its investment strategies. Shareholder votes for investment companies that fall within the categories listed in Parts I and II above are voted in accordance with those guidelines.

In the event Western Asset is required to vote on securities held in non-U.S. issuers – i.e. issuers that are incorporated under the laws of a foreign jurisdiction and that are not listed on a U.S. securities exchange or the NASDAQ stock market, the following guidelines are used, which are premised on the existence of a sound corporate governance and disclosure framework. These guidelines, however, may not be appropriate under some circumstances for foreign issuers and therefore apply only where applicable.

For accounts subject to ERISA, as well as other Retirement Accounts, Western Asset is presumed to have the responsibility to vote proxies for the client. The Department of Labor (“DOL”) has issued a bulletin that states that investment managers have the responsibility to vote proxies on behalf of Retirement Accounts unless the authority to vote proxies has been specifically reserved to another named fiduciary. Furthermore, unless Western Asset is expressly precluded from voting the proxies, the DOL has determined that the responsibility remains with the investment manager.

In order to comply with the DOL’s position, Western Asset will be presumed to have the obligation to vote proxies for its Retirement Accounts unless Western Asset has obtained a specific written instruction indicating that: (a) the right to vote proxies has been reserved to a named fiduciary of the client, and (b) Western Asset is precluded from voting proxies on behalf of the client. If Western Asset does not receive such an instruction, Western Asset will be responsible for voting proxies in the best interests of the Retirement Account client and in accordance with any proxy voting guidelines provided by the client.

The ratings of Moody’s Investors Service, Inc., S&P Global Ratings and Fitch Ratings represent their opinions as to the quality of various debt obligations. It should be emphasized, however, that ratings are not absolute standards of quality. Consequently, debt obligations with the same maturity, coupon and rating may have different yields while debt obligations of the same maturity and coupon with different ratings may have the same yield. As described by the rating agencies, ratings are generally given to securities at the time of issuances. While the rating agencies may from time to time revise such ratings, they undertake no obligation to do so.

Ratings assigned on Moody’s global long-term and short-term rating scales are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default. Short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default.^1,2

Moody’s issues ratings at the issuer level and instrument level on both the long-term scale and the short-term scale. Typically, ratings are made publicly available although private and unpublished ratings may also be assigned.³

Moody’s differentiates structured finance ratings from fundamental ratings (i.e., ratings on nonfinancial corporate, financial institution, and public sector entities) on the global long-term scale by adding (sf) to all structured finance ratings.⁴ The addition of (sf) to structured finance ratings should eliminate any presumption that such ratings and fundamental ratings at the same letter grade level will behave the same. The (sf) indicator for structured finance security ratings indicates that otherwise similarly rated structured finance and fundamental securities may have different risk characteristics. Through its current methodologies, however, Moody’s aspires to achieve broad expected equivalence in structured finance and fundamental rating performance when measured over a long period of time.

Description of Moody’s Investors Service, Inc.’s Global Long-Term Obligation Ratings:

Aaa—Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.

Aa—Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

A—Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.

Baa—Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.

Ba—Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.

B—Obligations rated B are considered speculative and are subject to high credit risk.

Caa—Obligations rated Caa are judged to be speculative of poor standing and are subject to very high credit risk.

Ca—Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C—Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody’s appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a “(hyb)” indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms.^*

By their terms, hybrid securities allow for the omission of scheduled dividends, interest, or principal payments, which can potentially result in impairment if such an omission occurs. Hybrid securities may also be subject to contractually allowable write-downs of principal that could result in impairment. Together with the hybrid indicator, the long-term obligation rating assigned to a hybrid security is an expression of the relative credit risk associated with that security.

Description of Moody’s Investors Service, Inc.’s Global Short-Term Obligation Ratings:

P-1—Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

P-2—Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

P-3—Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

NP—Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

While the global short-term “prime” rating scale is applied to US municipal tax-exempt commercial paper, these programs are typically backed by external letters of credit or liquidity facilities and their short-term prime ratings usually map to the long-term rating of the enhancing bank or financial institution and not to the municipality’s rating. Other short-term municipal obligations, which generally have different funding sources for repayment, are rated using two additional short-term rating scales (i.e., the MIG and VMIG scales discussed below).

The Municipal Investment Grade (“MIG”) scale is used to rate US municipal bond anticipation notes of up to three years maturity. Municipal notes rated on the MIG scale may be secured by either pledged revenues or proceeds of a take-out financing received prior to note maturity. MIG ratings expire at the maturity of the obligation, and the issuer’s long-term rating is only one consideration in assigning the MIG rating. MIG ratings are divided into three levels—MIG 1 through MIG 3—while speculative grade short-term obligations are designated SG.

MIG 1—This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.

MIG 2—This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.

MIG 3—This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.

SG—This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

In the case of variable rate demand obligations (“VRDOs”), a two-component rating is assigned: a long or short-term debt rating and a demand obligation rating. The first element represents Moody’s evaluation of risk associated with scheduled principal and interest payments. The second element represents Moody’s evaluation of risk associated with the ability to receive purchase price upon demand (“demand feature”). The second element uses a rating from a variation of the MIG scale called the

Variable Municipal Investment Grade (“VMIG”) scale. VMIG ratings of demand obligations with unconditional liquidity support are mapped from the short-term debt rating (or counterparty assessment) of the support provider, or the underlying obligor in the absence of third party liquidity support, with VMIG 1 corresponding to P-1, VMIG 2 to P-2, VMIG 3 to P-3 and SG to not prime. For example, the VMIG rating for an industrial revenue bond with Company XYZ as the underlying obligor would normally have the same numerical modifier as Company XYZ’s prime rating. Transitions of VMIG ratings of demand obligations with conditional liquidity support, as shown in the diagram below, differ from transitions on the Prime scale to reflect the risk that external liquidity support will terminate if the issuer’s long-term rating drops below investment grade.

VMIG 1—This designation denotes superior credit quality. Excellent protection is afforded by the superior short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.

VMIG 2—This designation denotes strong credit quality. Good protection is afforded by the strong short- term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.

VMIG 3—This designation denotes acceptable credit quality. Adequate protection is afforded by the satisfactory short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.

SG—This designation denotes speculative-grade credit quality. Demand features rated in this category may be supported by a liquidity provider that does not have an investment grade short-term rating or may lack the structural and/or legal protections necessary to ensure the timely payment of purchase price upon demand.

*—For VRDBs supported with conditional liquidity support, short-term ratings transition down at higher long-term ratings to reflect the risk of termination of liquidity support as a result of a downgrade below investment grade.

VMIG ratings of VRDBs with unconditional liquidity support reflect the short-term debt rating (or counterparty assessment) of the liquidity support reflect the short-term debt rating (or counterparty assessment) of the liquidity support provider with VMIG 1 corresponding to P-1, VMIG 2 to P-2, VMIG 3 to P-3 and SG to not prime.

Long-Term Issue Credit Ratings are based, in varying degrees, on S&P Global Ratings’ analysis of the following considerations:

An issue rating is an assessment of default risk, but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

AAA—An obligation rated “AAA” has the highest rating assigned by S&P Global Ratings. The obligor’s capacity to meet its financial commitments on the obligation is extremely strong.

AA—An obligation rated “AA” differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitments on the obligation is very strong.

A—An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitments on the obligation is still strong.

BBB—An obligation rated “BBB” exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor’s capacity of the obligor to meet its financial commitments on the obligation.

BB, B, CCC, CC, and C—Obligations rated “BB”, “B”, “CCC”, “CC”, and “C” are regarded as having significant speculative characteristics. “BB” indicates the least degree of speculation and “C” the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposure to adverse conditions.

BB—An obligation rated “BB” is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions that could lead to the obligor’s inadequate capacity to meet its financial commitments on the obligation.

B—An obligation rated “B” is more vulnerable to nonpayment than obligations rated “BB”, but the obligor currently has the capacity to meet its financial commitments on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitments on the obligation.

CCC—An obligation rated “CCC” is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitments on the obligation.

The “CC” rating is used when a default has not yet occurred, but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.

C—An obligation rated “C” is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher.

D—An obligation rated “D” is in default or in breach of an imputed promise. For non-hybrid capital instruments, the “D” rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The “D” rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to “D” if it is subject to a distressed exchange offer.

Ratings from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the rating categories.

A-1—A short-term obligation rated “A-1” is rated in the highest category by S&P Global Ratings. The obligor’s capacity to meet its financial commitments on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitments on these obligations is extremely strong.

A-2—A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitments on the obligation is satisfactory.

A-3—A short-term obligation rated “A-3” exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken an obligor’s capacity to meet its financial commitments on the obligation.

B—A short-term obligation rated “B” is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties that could lead to the obligor’s inadequate capacity to meet its financial commitments.

C—A short-term obligation rated “C” is currently vulnerable to nonpayment and is dependent on favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation.

D—A short-term obligation rated “D” is in default or in breach of an imputed promise. For non-hybrid capital instruments, the “D” rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings’ believes that such payments will be made within any stated grace period.

However, any stated grace period longer than five business days will be treated as five business days. The “D” rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to “D” if it is subject to a distressed exchange offer.

An S&P Global Ratings U.S. municipal note rating reflects S&P Global Ratings opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P Global Ratings’ analysis will review the following considerations:

SP-1—Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2—Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

D—“D” is assigned upon failure to pay the note when due, completion of a distressed exchange offer, or the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions.

Dual ratings may be assigned to debt issues that have a put option or demand feature. The first component of the rating addresses the likelihood of repayment of principal and interest as due, and the second component of the rating addresses only the demand feature. The first component of the rating can relate to either a short-term or long-term transaction and accordingly use either short-term or long-term rating symbols. The second component of the rating relates to the put option and is assigned a short-term rating symbol (for example, “AAA/A-1+” or “A-1+/A-1”). With U.S. municipal short-term demand debt, the U.S. municipal short-term note rating symbols are used for the first component of the rating (for example, “SP-1+/A-1+”).

Description of S&P Global Ratings’ Active Qualifiers (Currently applied and/or outstanding):

S&P Global Ratings uses the following qualifiers that limit the scope of a rating. The structure of the transaction can require the use of a qualifier such as a “p” qualifier, which indicates the rating addresses the principal portion of the obligation only. A qualifier appears as a suffix and is part of the rating.

Federal deposit insurance limit: “L” qualifier. Ratings qualified with “L” apply only to amounts invested up to federal deposit insurance limits.

Principal: “p” qualifier. This suffix is used for issues in which the credit factors, the terms, or both, that determine the likelihood of receipt of payment of principal are different from the credit factors, terms or both that determine the likelihood of receipt of interest on the obligation. The “p” suffix indicates that the rating addresses the principal portion of the obligation only and that the interest is not rated.

Preliminary ratings: “prelim” qualifier. Preliminary ratings, with the “prelim” suffix, may be assigned to obligors or obligations, including financial programs, in the circumstances described below. Assignment of a final rating is conditional on the receipt by S&P Global Ratings of appropriate documentation. S&P Global Ratings reserves the right not to issue a final rating. Moreover, if a final rating is issued, it may differ from the preliminary rating.

Preliminary ratings may also be assigned to the obligors. These ratings consider the anticipated general credit quality of the reorganized or post-bankruptcy issuer as well as attributes of the anticipated obligation(s).

Termination structures: “t” qualifier. This symbol indicates termination structures that are designed to honor their contracts to full maturity or, should certain events occur, to terminate and cash settle all their contracts before their final maturity date.

Counterparty instrument rating: “cir” qualifier. This symbol indicates a counterparty instrument rating (CIR), which is a forward-looking opinion about the creditworthiness of an issuer in a securitization structure with respect to a specific financial obligation to a counterparty (including interest rate swaps, currency swaps, and liquidity facilities). The CIR is determined on an ultimate payment basis; these opinions do not take into account timeliness of payment.

Description of Fitch Ratings’ Corporate Finance Long-Term Obligation Ratings:

Ratings of individual securities or financial obligations of a corporate issuer address relative vulnerability to default on an ordinal scale. In addition, for financial obligations in corporate finance, a measure of recovery given default on that liability is also included in the rating assessment. This notably applies to covered bonds ratings, which incorporate both an indication of the probability of default and of the recovery given a default of this debt instrument. On the contrary, ratings of debtor-in-possession (DIP) obligations incorporate the expectation of full repayment.

The relationship between the issuer scale and obligation scale assumes a generic historical average recovery. Individual obligations can be assigned ratings, higher, lower, or the same as the entity’s issuer rating or IDR, based on their relative ranking, relative vulnerability to default or based on explicit Recovery Ratings. As a result, individual obligations of entities, such as corporations, are assigned ratings higher, lower, or the same as that entity’s issuer rating or IDR, except DIP obligation ratings that are not based off an IDR. At the lower end of the ratings scale, Fitch publishes explicit Recovery Ratings in many cases to complement issuer and obligation ratings.

AAA: Highest credit quality. “AAA” ratings denote the lowest expectation of credit risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA: Very high credit quality. “AA” ratings denote expectations of very low credit risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A: High credit quality. “A” ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

BBB: Good credit quality. “BBB” ratings indicate that expectations of credit risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.

BB: Speculative. “BB” ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met.

B: Highly speculative. “B” ratings indicate that material credit risk is present.

CCC: Substantial credit risk. “CCC” ratings indicate that substantial credit risk is present.

CC: Very high levels of credit risk. “CC” ratings indicate very high levels of credit risk.

C: Exceptionally high levels of credit risk. “C” indicates exceptionally high levels of credit risk. Defaulted obligations typically are not assigned “RD” or “D” ratings, but are instead rated in the “CCC” to “C” rating categories, depending upon their recovery prospects and other relevant characteristics. This approach better aligns obligations that have comparable overall expected loss but varying vulnerability to default and loss.

Description of Fitch Ratings’ Structured Finance Long-Term Obligation Ratings:

Ratings of public finance obligations and ratings of infrastructure and project finance obligations on the long-term scale consider the obligations’ relative vulnerability to default. These ratings are typically assigned to an individual security, instrument or tranche in a transaction. In limited cases in U.S. public finance, where Chapter 9 of the Bankruptcy Code provides reliably superior prospects for ultimate recover to local government obligations that benefit from a statutory lien on revenues, Fitch reflects this in a security rating with limited notching above the IDR. Recover expectations can also be reflected in a security rating in the U.S. during the pendency of a bankruptcy proceeding under the Code if there is sufficient visibility on potential recover prospects.

AAA: Highest credit quality. “AAA” ratings denote the lowest expectation of default risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA: Very high credit quality. “AA” ratings denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A: High credit quality. “A” ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

BBB: Good credit quality. “BBB” ratings indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.

BB: Speculative. “BB” ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time.

B: Highly speculative. “B” ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.

C: Exceptionally high levels of credit risk. Default appears imminent or inevitable.

D: Default. Indicates a default. Default generally is defined as one of the following:

Notes: In U.S. public finance, obligations may be pre-refunded, where funds sufficient to meet the requirements of the respective obligations are placed in an escrow account. When obligation ratings are maintained based on the escrowed funds and their structural elements, the ratings carry the suffix “pre” (e.g. “AAApre”, “AA+pre”).

Description of Fitch Ratings’ Corporate, Public and Structured Finance Short-Term Obligation Ratings:

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations, and up to 36 months for obligations in U.S. public finance markets.

F1: Highest Short-Term Credit Quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

F2: Good Short-Term Credit Quality. Good intrinsic capacity for timely payment of financial commitments.

F3: Fair Short-Term Credit Quality. The intrinsic capacity for timely payment of financial commitments is adequate.

B: Speculative Short-Term Credit Quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.

RD: Restricted Default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.

D: Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Article IX of the Registrant’s Declaration of Trust addresses the limitation of liability and indemnification of the Registrant’s Trustees, officers and others. Section 9.2(a) of the Declaration of Trust provides that no current or former Trustee, officer, or employee of the Registrant will be subject to any personal liability whatsoever to any person, other than the Registrant or its shareholders, in connection with the affairs of the Registrant. Further, Section 9.2(b) of the Declaration of Trust provides that, subject to applicable federal law, no current or former Trustee or officer of the Registrant will be liable to the Registrant or to any shareholder for money damages except:

Section 9.5 of the Declaration of Trust requires that, subject to certain exceptions and limitations expressed in the Declaration of Trust, each current and former Trustee, officer, or employee of the Registrant, including persons who serve at the request of the Registrant as directors, trustees, officers, employees, agents or independent contractors of another organization in which the Registrant has an interest as a shareholder, creditor or otherwise (each, a “Covered Person”), be indemnified by the Registrant to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim in which he becomes involved as a party or otherwise by virtue of his being (or having served) in such position and against amounts paid or incurred by him in settlement thereof. Section 9.5 of the Declaration of Trust further provides that no indemnification shall be provided to the extent such indemnification is prohibited by applicable federal law. The Declaration of Trust also sets forth provisions outlining presumptions that may be made relating to a person’s standard of conduct and when expenses may be advanced.

In addition to the foregoing, the Registrant has entered into an Indemnification Agreement with each of its Trustees that provides for indemnification consistent with the principles described above. These Indemnification Agreements set forth certain procedural aspects with respect to indemnification, including the advancement of expenses, and presumptions relating to the determination of whether the standard of conduct required for indemnification has been met, as well as remedies for the indemnitee in the event that, among other things, determinations as to entitlement to indemnification, advancement of expenses and indemnity payments are not made in accordance with the procedures specified therein.

The Trustees and officers of the Registrant and the personnel of the Registrant’s manager are insured under an errors and omissions liability insurance policy. The Registrant and its officers are also insured under the fidelity bond required by Rule 17g-1 under the Investment Company Act of 1940, as amended. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be provided to Trustees, officers and controlling persons of the Registrant, pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a Trustee, officer or controlling person of the Registrant in connection with the successful defense of any action, suit or proceeding or payment pursuant to any insurance policy) is asserted against the Registrant by such Trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is prohibited as against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Under the Distribution Agreement, the Registrant agrees to indemnify LMIS, its officers, directors and employees and any person who controls LMIS within the meaning of Section 15 of the Securities Act, free and harmless from and against any and all claims, demands, liabilities and expenses (including the reasonable cost of investigating or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which LMIS, its officers, directors and employees or any such controlling person may incur, under the Securities Act or under common law or otherwise, arising out of or based upon any alleged untrue statement of a material fact contained in the Registrant’s Registration Statement or arising out of or based upon any alleged omission to state a material fact required to be stated or necessary to make the Registration Statement not misleading, provided that in no event shall anything contained in the Distribution Agreement be construed so as to protect LMIS or such other parties against any liability to the Registrant or its shareholders to which LMIS or such other parties would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence in the performance of their duties, or by reason of reckless disregard of their obligations and duties under the Distribution Agreement.

The Registrant’s Management Agreements and Subadvisory Agreements provide that the manager or subadvisor, as applicable, assumes no responsibility under the Agreements other than to render the services called for under the Agreements in good faith. The Management Agreements and Subadvisory Agreements further provide that the manager or the subadvisor, as applicable, shall not be liable for any error of judgment or mistake of law, or for any loss arising out of any investment or for any act or omission in the execution of securities transactions for the fund, provided that nothing in the Agreements protect with the manager or the subadvisor, as applicable, against any liability to the Fund to which the manager or subadvisor, as applicable, would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the Agreements.

Generally		You may buy shares of a fund on any day that the fund is open for business, as described under “Share price/Fund business days.” Shares are sold at their net asset value next determined after receipt by your Service Agent or the transfer agent of your purchase request in good order. A fund may not be available for sale in certain states. Prospective investors should inquire as to whether a fund is available for sale in their state of residence. You must provide the following information for your order to be processed: • Name of fund being bought • Class of shares being bought • Dollar amount or number of shares being bought • Account number (if existing account)

Through a Service Agent		You should contact your Service Agent to open an account and make arrangements to buy shares. You must contact your Service Agent to arrange for the wiring of federal funds.

It is your Service Agent’s responsibility to transmit orders to the fund’s transfer agent in a timely fashion.

Generally		You may exchange shares of a fund for the corresponding share class, if offered, of any other Western Asset money market fund made available to you on any day that both the fund and the fund into which you are exchanging are open for business. An exchange of shares of one fund for shares of another fund is generally a taxable transaction, but for each of Premier Institutional Government Reserves and Premier Institutional U.S. Treasury Reserves you will not have any gain or loss on an exchange so long as the fund whose shares you exchange maintains a net asset value of $1.00 per share.

Western Asset offers a distinctive family of money market funds tailored to help meet the varying needs of large and small investors		You may exchange shares at the final net asset value calculated on a fund business day after receipt by your Service Agent or the transfer agent of your exchange request in good order. • If you are a customer of a Service Agent, contact your Service Agent to learn which funds your Service Agent makes available to you for exchanges.

Box 9699 Providence, RI 02940-9699 Express, Certified or Registered Mail: Western Asset Money Market Funds 4400 Computer Drive Westborough, MA 01581



Generally		You may redeem shares of a fund on any day that the fund is open for business, as described under “Share price/Fund business days” below. However, Premier Institutional Liquid Reserves may impose a liquidity fee or temporarily restrict redemptions from the fund under certain circumstances, as set forth below under “Redemption Fees and Gates.” Shares are redeemed at their net asset value next determined after receipt by your Service Agent or the transfer agent of your redemption request in good order. If the shares are held by a fiduciary or corporation, partnership or similar entity, other documents may be required. Contact your Service Agent or, if you hold shares directly with a fund, call the fund at 1-877-721-1926 or 1-203-703-6002 to redeem shares of the fund.

Redemption proceeds		For Premier Institutional Government Reserves: You normally will receive your redemption proceeds in federal funds on the business day on which you sell your shares, or if your redemption request is received in good order by your Service Agent or the transfer agent after the fund makes it final net asset value calculation on that business day (normally 5:00 p.m. (Eastern time)), on the next business day. The fund may delay payment for one business day under certain circumstances and may delay beyond one business day if Fedwire or the applicable Federal Reserve Bank is closed on the day your redemption proceeds would otherwise be paid, or in the circumstances described below.
		For Premier Institutional U.S. Treasury Reserves: You normally will receive your redemption proceeds in federal funds on the business day on which you sell your shares, or if your redemption request is received in good order by your Service Agent or the transfer agent after the fund makes its final net asset value calculation on that business day (normally 2:00 p.m. (Eastern time)), on the next business day. The fund may delay payment for one business day under certain circumstances and may delay beyond one business day if Fedwire or the applicable Federal Reserve Bank is closed on the day your redemption proceeds would otherwise be paid, or in the circumstances described below.
		For Premier Institutional Liquid Reserves: If your request is received in good order by the transfer agent prior to the time the fund makes its final net asset value calculation on any day the fund is open for business (normally 3:00 p.m. (Eastern time)), your redemption proceeds normally will be sent that day, but in any event within 7 days.
		For all funds: You generally are entitled to receive dividends on fund shares through the business day prior to the day on which your proceeds are sent to you.
		Your redemption proceeds may be delayed, or your right to receive redemption proceeds suspended beyond 7 days, if the NYSE is closed (other than on weekends or holidays) or trading is restricted, if an emergency exists, or otherwise as permitted by the rules of or by the order of the SEC.
		If you hold your shares through a Service Agent, your Service Agent may have its own earlier deadlines for the receipt of a redemption request. All orders through a Service Agent are processed at the net asset value next calculated by the fund following receipt by the fund’s transfer agent of your redemption request in good order. It is your Service Agent’s responsibility to transmit orders to the fund’s transfer agent in a timely fashion. Your sale or redemption proceeds will be sent by federal wire to your Service Agent. You should check with your Service Agent to determine when your proceeds will be available to you.
		If you hold your shares through a fund and have designated a bank account on your application form, you may have the proceeds sent by federal wire or by electronic transfer (ACH) to that bank account. To change the bank account designated to receive wire or electronic transfers, you will be required to deliver a new written authorization and may be asked to provide other documents. You may be charged a fee on a wire or an electronic transfer (ACH). In other cases, unless you direct otherwise, your proceeds will be paid by check mailed to your address of record.
		Under normal circumstances, each fund expects to meet redemption requests by using cash or cash equivalents in its portfolio.
		The funds reserve the right to pay redemption proceeds by giving you securities instead of cash (for example, if a fund reasonably believes that a cash redemption may have a substantial impact on the fund and its remaining shareholders). You may pay transaction costs to dispose of the securities, and you may receive less than the price at which they were valued for purposes of the redemption.

		During periods of deteriorating or stressed market conditions, or during extraordinary or emergency circumstances, a fund may be more likely to pay redemption proceeds by giving you securities.

By mail		Contact your Service Agent or, if you hold shares directly with a fund, write to the fund as follows:

Redemption Fee and Gates		For Premier Institutional Liquid Reserves: The fund may impose a liquidity fee of up to 2% on redemptions from the fund or temporarily restrict redemptions from the fund for up to 10 business days in any given 90 day period (a “redemption gate”) in the event that the fund’s weekly liquid assets fall below the following thresholds: • 30% weekly liquid assets¹—if the fund’s weekly liquid assets fall below 30% of the fund’s total assets, and the Board of Trustees of the fund determines that it is in the best interests of the fund, the fund may, as early as the same day, impose a liquidity fee of not more than 2% of the amount redeemed or a redemption gate that temporarily suspends the right of redemption. • 10% weekly liquid assets—if the fund’s weekly liquid assets fall below 10% of the fund’s total assets, the fund will impose at the beginning of the next business day, a liquidity fee of 1% of the amount redeemed, unless the Board of Trustees of the fund determines that imposing such a fee would not be in the best interests of the fund or determines that a lower or higher fee (not to exceed 2%) would be in the best interests of the fund. If the fund imposes a redemption gate, the fund and the fund’s authorized agent or intermediary will not accept redemption orders until the fund has notified shareholders that the redemption gate has been lifted. Any redemption orders submitted while a redemption gate is in effect will be cancelled without further notice. Pending redemption orders may be affected if the fund imposes a redemption gate. If you still wish to redeem shares once the redemption gate has been lifted, you will need to submit a new redemption request to the fund or the fund’s authorized agent or intermediary. Liquidity fees and redemption gates may be terminated at any time at the judgment of the Board of Trustees. In addition, liquidity fees and redemption gates will terminate at the beginning of the next business day once the fund has invested 30% or more of its total assets in weekly liquid assets. The fund may only suspend redemptions for up to 10 business days in any 90-day period. A liquidity fee imposed by the fund will reduce the amount you will receive upon the redemption of your shares, and could cause you to recognize a capital loss or could decrease the capital gain or increase the capital loss you would otherwise recognize. Liquidity fees would be retained by the fund. Pending redemption orders may be affected if the fund imposes a liquidity fee.
