Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including sales charges (loads) on Fund purchases and redemptions; and (2) ongoing Fund costs, including management fees, distribution and service (12b-1) fees, and other Fund expenses. All mutual funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other mutual funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row for your class of shares under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 x $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example for the class of shares you hold with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

		Actual		Hypothetical

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 184/365 to reflect the one-half year period.

2. Reflects expenses after fee waivers and expense reimbursements. Does not include acquired fund fees and expenses.

The Fund calculates the net asset value (NAV) per share each business day as of 4 p.m. Eastern time or the regularly scheduled close of the New York Stock Exchange (NYSE), whichever is earlier. Under compliance policies and procedures approved by the Trust’s Board of Trustees (the Board), the Fund’s administrator has responsibility for oversight of valuation, including leading the cross-functional Valuation Committee (VC). The Fund may utilize independent pricing services, quotations from securities and financial instrument dealers, and other market sources to determine fair value. Equity securities listed on an exchange or on the NASDAQ National Market System are valued at the last quoted sale price or the official closing price of the day, respectively.Over-the-counter (OTC) securities are valued within the rangeof the most recent quoted bid and ask prices. Securities that trade in multiple markets or on multiple exchanges are valuedaccording to the broadest and most representative market.Certain equity securities are valued based upon fundamentalcharacteristics or relationships to similar securities. Debt securities generally trade in the OTC market rather than on a securities exchange. The Fund’s pricing services use multiple valuation techniques to determine fair value. In instances where sufficient market activity exists, the pricing services may utilize a market-based approach through which quotes from market makers are used to determine fair value. In instances where sufficient market activity may not exist or is limited, the pricing services also utilize proprietary valuation models which may consider market characteristics such as benchmark yield curves,credit spreads, estimated default rates, anticipated market interest rate volatility, coupon rates, anticipated timing of principal repayments, underlying collateral, and other unique security features in order to estimate the relevant cash flows, which are then discounted to calculate the fair value. Investments in repurchase agreements are valued at cost, whichapproximates fair value. Certain derivative financial instruments are centrally cleared ortrade in the OTC market. The Fund’s pricing services usevarious techniques including industry standard option pricing models and proprietary discounted cash flow models todetermine the fair value of those instruments. The Fund’s net benefit or obligation under the derivative contract, as measured by the fair value of the contract, is included in net assets. The Fund has procedures to determine the fair value of financial instruments for which market prices are not reliable or readily available. Under these procedures, the Fund primarily employs a market-based approach which may use related or comparable assets or liabilities, recent transactions, market multiples, book values, and other relevant information for the investment to determine the fair value of the investment. An income-based valuation approach may also be used in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Due to the inherent uncertainty of valuations ofsuch investments, the fair values may differ significantly from the values that would have been used had an active market existed. b. Joint Repurchase Agreement The Fund enters into a joint repurchase agreement whereby itsuninvested cash balance is deposited into a joint cash accountwith other funds managed by the investment manager or anaffiliate of the investment manager and is used to invest in oneor more repurchase agreements. The value and face amount of the joint repurchase agreement are allocated to the funds based on their pro-rata interest. A repurchase agreement is accounted for as a loan by the Fund to the seller, collateralized by securities which are delivered to the Fund’s custodian. The fair value, including accrued interest, of the initial collateralization is required to be at least 102% of the dollar amount invested by

1. Organization and Significant AccountingPolicies(continued) b. Joint Repurchase Agreement(continued) the funds, with the value of the underlying securities marked tomarket daily to maintain coverage of at least 100%. Repurchaseagreements are subject to the terms of Master RepurchaseAgreements (MRAs) with approved counterparties (sellers).The MRAs contain various provisions, including but not limitedto events of default and maintenance of collateral for repurchaseagreements. In the event of default by either the seller or theFund, certain MRAs may permit the non-defaulting party to netand close-out all transactions, if any, traded under suchagreements. The Fund may sell securities it holds as collateraland apply the proceeds towards the repurchase price and anyother amounts owed by the seller to the Fund in the event ofdefault by the seller. This could involve costs or delays inaddition to a loss on the securities if their value falls below therepurchase price owed by the seller. The joint repurchaseagreement held by the Fund at period end, as indicated in theStatement of Investments, had been entered into on January 31,2019. c. Securities Purchased on a Delayed Delivery Basis The Fund purchases securities on a delayed delivery basis, withpayment and delivery scheduled for a future date. Thesetransactions are subject to market fluctuations and are subject tothe risk that the value at delivery may be more or less than thetrade date purchase price. Although the Fund will generallypurchase these securities with the intention of holding thesecurities, it may sell the securities before the settlement date.Sufficient assets have been segregated for these securities. d. Derivative Financial Instruments The Fund invested in derivative financial instruments in order tomanage risk or gain exposure to various other investments ormarkets. Derivatives are financial contracts based on anunderlying or notional amount, require no initial investment oran initial net investment that is smaller than would normally berequired to have a similar response to changes in market factors,and require or permit net settlement. Derivatives contain variousrisks including the potential inability of the counterparty tofulfill their obligations under the terms of the contract, the potential for an illiquid secondary market, and/or the potentialfor market movements which expose the Fund to gains or lossesin excess of the amounts shown in the Statement of Assets and Liabilities. Realized gain and loss and unrealized appreciationand depreciation on these contracts for the period are includedin the Statement of Operations. Collateral requirements differ by type of derivative. Collateralor initial margin requirements are set by the broker or exchangeclearing house for exchange traded and centrally clearedderivatives. Initial margin deposited is held at the exchange andcan be in the form of cash and/or securities. The Fund entered into credit default swap contracts primarily tomanage and/or gain exposure to credit risk. A credit defaultswap is an agreement between the Fund and a counterpartywhereby the buyer of the contract receives credit protection andthe seller of the contract guarantees the credit worthiness of areferenced debt obligation. These agreements may be privatelynegotiated in the over-the-counter market (OTC credit defaultswaps) or may be executed in a multilateral trade facilityplatform, such as a registered exchange (centrally cleared creditdefault swaps). The underlying referenced debt obligation maybe a single issuer of corporate or sovereign debt, a credit index,a basket of issuers or indices, or a tranche of a credit index orbasket of issuers or indices. In the event of a default of theunderlying referenced debt obligation, the buyer is entitled toreceive the notional amount of the credit default swap contract from the seller in exchange for the referenced debt obligation, a net settlement amount equal to the notional amount of the credit default swap less the recovery value of the referenced debt obligation, or other agreed upon amount. For centrally cleared credit default swaps, required initial margins are pledged by the Fund, and the daily change in fair value is accounted for as a variation margin payable or receivable in the Statement of Assets and Liabilities. Over the term of the contract, the buyer pays the seller a periodic stream of payments, provided that no event of default has occurred. Such periodic payments are accrued daily as an unrealized appreciation or depreciation untilthe payments are made, at which time they are realized. Upfrontpayments and receipts are reflected in the Statement of Assetsand Liabilities and represent compensating factors betweenstated terms of the credit default swap agreement and prevailingmarket conditions (credit spreads and other relevant factors).These upfront payments and receipts are amortized over theterm of the contract as a realized gain or loss in the Statement ofOperations. See Note 9 regarding other derivative information.

e. Senior Floating Rate Interests
The Fund invests in senior secured corporate loans that payinterest at rates which are periodically reset by reference to abase lending rate plus a spread. These base lending rates aregenerally the prime rate offered by a designated U.S. bank orthe London InterBank Offered Rate (LIBOR). Senior securedcorporate loans often require prepayment of principal fromexcess cash flows or at the discretion of the borrower. As aresult, actual maturity may be substantially less than the statedmaturity. Senior secured corporate loans in which the Fundinvests are generally readily marketable, but may be subject tocertain restrictions on resale. f. Income Taxes The Fund is a disregarded entity for U.S. income tax purposes.As such, no provision has been made for income taxes becauseall income, expenses, gains and losses are allocated to anon-U.S. beneficial owner for inclusion in its individual incometax return, as applicable. g. Security Transactions, Investment Income, Expenses andDistributions Security transactions are accounted for on trade date. Realized gains and losses on security transactions are determined on aspecific identification basis. Interest income and estimatedexpenses are accrued daily. Amortization of premium andaccretion of discount on debt securities are included in interestincome. Facility fees are recognized as income over theexpected term of the loan. Dividend income is recorded on theex-dividend date. The Fund’s net investment income isallocated to the owner daily and paid monthly. Net capital gains(or losses) realized by the Fund will not be distributed.Distributions to shareholders are recorded on the ex-dividenddate. Distributable earnings are determined according to income tax regulations (tax basis) and may differ from earningsrecorded in accordance with U.S. GAAP. These differencesmay be permanent or temporary. Permanent differences arereclassified among capital accounts to reflect their tax character.These reclassifications have no impact on net assets or theresults of operations. Temporary differences are not reclassified,
as they may reverse in subsequent periods.* Common expenses incurred by the Trust are allocated amongthe Funds based on the ratio of net assets of each Fund to thecombined net assets of the Trust or based on the ratio of numberof shareholders of each Fund to the combined number ofshareholders of the Trust. Fund specific expenses are chargeddirectly to the Fund that incurred the expense. h. Accounting Estimates The preparation of financial statements in accordance with U.S.GAAP requires management to make estimates andassumptions that affect the reported amounts of assets andliabilities at the date of the financial statements and the amountsof income and expenses during the reporting period. Actualresults could differ from those estimates. i. Guarantees and Indemnifications Under the Trust’s organizational documents, its officers andtrustees are indemnified by the Trust against certain liabilitiesarising out of the performance of their duties to the Trust.Additionally, in the normal course of business, the Trust, onbehalf of the Fund, enters into contracts with service providersthat contain general indemnification clauses. The Trust’smaximum exposure under these arrangements is unknown asthis would involve future claims that may be made against theTrust that have not yet occurred. Currently, the Trust expectsthe risk of loss to be remote.

*Effective during the current reporting period, it is no longer required to present certain line items in the Statements of Changes inNet Assets. The below prior period amounts affected by this change are shown as they were in the prior year Statements of Changesin Net Assets.

12. Credit Facility

The Fund, together with other U.S. registered and foreign investment funds (collectively, Borrowers), managed by Franklin Templeton, are borrowers in a joint syndicated senior unsecured credit facility totaling $2 billion (Global Credit Facility) which matured on February 8, 2019. This Global Credit Facility provides a source of funds to the Borrowers for temporary and emergency purposes, including the ability to meet future unanticipated or unusually large redemption requests. Effective February 8, 2019, the Borrowers renewed the Global Credit Facility for a one year term, maturing February 7, 2020, for a total of $2 billion.

Under the terms of the Global Credit Facility, the Fund shall, in addition to interest charged on any borrowings made by the Fund and other costs incurred by the Fund, pay its share of fees and expenses incurred in connection with the implementation and maintenance of the Global Credit Facility, based upon its relative share of the aggregate net assets of all of the Borrowers, including an annual commitment fee of 0.15% based upon the unused portion of the Global Credit Facility. These fees are reflected in other expenses in the Statement of Operations. During the period ended January 31, 2019, the Fund did not use the Global Credit Facility.

13. Fair Value Measurements

The Fund follows a fair value hierarchy that distinguishes between market data obtained from independent sources (observable inputs) and the Fund’s own market assumptions (unobservable inputs). These inputs are used in determining the value of the Fund’s financial instruments and are summarized in the following fair value hierarchy:

• Level 1 – quoted prices in active markets for identical financial instruments
• Level 2 – other significant observable inputs (including quoted prices for similar financial instruments, interest rates,prepayment speed, credit risk, etc.)
• Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of financialinstruments)

The input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level.

FRANKLIN LOWER TIER FLOATING RATE FUND

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including sales charges (loads) on Fund purchases and redemptions; and (2) ongoing Fund costs, including management fees, distribution and service (12b-1) fees, and other Fund expenses. All mutual funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other mutual funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row for your class of shares under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 x $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example for the class of shares you hold with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 184/365 to reflect the one-half year period.

2. Reflects expenses after fee waivers and expense reimbursements. Does not include acquired fund fees and expenses.

Notes to Financial Statements (unaudited)

1. Organization and Significant Accounting Policies Franklin Floating Rate Master Trust (Trust) is registered under the Investment Company Act of 1940 (1940 Act) as an open-end management investment company, consisting of three separate funds, two of which are included in this report (Funds) and applies the specialized accounting and reporting guidance in U.S. Generally Accepted Accounting Principles (U.S.GAAP). The shares are issued in private placements and exemptfrom registration under the Securities Act of 1933. The following summarizes the Funds’ significant accountingpolicies. a. Financial Instrument Valuation The Funds’ investments in financial instruments are carried at fair value daily. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The Funds calculate the net asset value (NAV) per share each business day as of 4 p.m. Eastern time or the regularly scheduled close of the New York Stock Exchange (NYSE), whichever is earlier. Under compliance policies and procedures approved by the Trust’s Board of Trustees (the Board), the Funds’ administrator has responsibility for oversight of valuation, including leading the cross-functional ValuationCommittee (VC). The Funds may utilize independent pricing services, quotations from securities and financial instrumentdealers, and other market sources to determine fair value. Equity securities listed on an exchange or on the NASDAQ National Market System are valued at the last quoted sale price or the official closing price of the day, respectively.Over-the-counter (OTC) securities are valued within the range of the most recent quoted bid and ask prices. Securities that trade in multiple markets or on multiple exchanges are valued according to the broadest and most representative market.Certain equity securities are valued based upon fundamentalcharacteristics or relationships to similar securities. Debt securities generally trade in the OTC market rather than on a securities exchange. The Funds’ pricing services use multiple valuation techniques to determine fair value. In instances where sufficient market activity exists, the pricing services may utilize a market-based approach through which quotes from market makers are used to determine fair value. In instances where sufficient market activity may not exist or is limited, the pricing services also utilize proprietary valuation models which may consider market characteristics such as benchmark yield curves,credit spreads, estimated default rates, anticipated market interest rate volatility, coupon rates, anticipated timing of principal repayments, underlying collateral, and other unique security features in order to estimate the relevant cash flows, which are then discounted to calculate the fair value. Investments in open-end mutual funds are valued at the closingNAV. The Funds have procedures to determine the fair value of financial instruments for which market prices are not reliable orreadily available. Under these procedures, the Funds primarily employ a market-based approach which may use related or comparable assets or liabilities, recent transactions, market multiples, book values, and other relevant information for the investment to determine the fair value of the investment. An income-based valuation approach may also be used in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed. b. Securities Purchased on a Delayed Delivery Basis Certain or all Funds purchase securities on a delayed deliverybasis, with payment and delivery scheduled for a future date.These transactions are subject to market fluctuations and are subject to the risk that the value at delivery may be more or less than the trade date purchase price. Although the Funds willgenerally purchase these securities with the intention of holding the securities, they may sell the securities before the settlement date. Sufficient assets have been segregated for these securities. c. Senior Floating Rate Interests Certain or all Funds invest in senior secured corporate loans that pay interest at rates which are periodically reset by reference toa base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or the London InterBank Offered Rate (LIBOR). Senior secured corporate loans often require prepayment of principal from excess cash flows or at the discretion of the borrower. As a result, actual maturity may be substantially less than the stated

1. Organization and Significant AccountingPolicies(continued) c. Senior Floating Rate Interests(continued) maturity. Senior secured corporate loans in which the Funds invest are generally readily marketable, but may be subject to certain restrictions on resale. d. Income Taxes It is each Fund’s policy to qualify as a regulated investment company under the Internal Revenue Code. Each Fund intendsto distribute to shareholders substantially all of its taxable income and net realized gains to relieve it from federal income and excise taxes. As a result, no provision for U.S. federal income taxes is required. Each Fund may recognize an income tax liability related to its uncertain tax positions under U.S. GAAP when the uncertaintax position has a less than 50% probability that it will besustained upon examination by the tax authorities based on its technical merits. As of January 31, 2019, each Fund has determined that no tax liability is required in its financial statements related to uncertain tax positions for any open tax years (or expected to be taken in future tax years). Open tax years are those that remain subject to examination and are based on the statute of limitations in each jurisdiction in which theFund invests. e. Security Transactions, Investment Income, Expenses and Distributions Security transactions are accounted for on trade date. Realized gains and losses on security transactions are determined on a specific identification basis. Interest income and estimated expenses are accrued daily. Amortization of premium and accretion of discount on debt securities are included in interest income. Facility fees are recognized as income over the expected term of the loan. Dividend income is recorded on the ex-dividend date. Dividends from net investment income are normally declared daily; these dividends may be reinvested or paid monthly to shareholders. Distributions from realizedcapital gains and other distributions, if any, are recorded on the ex-dividend date. Distributable earnings are determinedaccording to income tax regulations (tax basis) and may differfrom earnings recorded in accordance with U.S. GAAP. These differences may be permanent or temporary. Permanent differences are reclassified among capital accounts to reflect their tax character. These reclassifications have no impact onnet assets or the results of operations. Temporary differencesare not reclassified, as they may reverse in subsequent periods.* Common expenses incurred by the Trust are allocated among the Funds based on the ratio of net assets of each Fund to the combined net assets of the Trust or based on the ratio of number of shareholders of each Fund to the combined number of shareholders of the Trust. Fund specific expenses are chargeddirectly to the Fund that incurred the expense. f. Accounting Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the amounts of income and expenses during the reporting period. Actual results could differ from those estimates. g. Guarantees and Indemnifications Under the Trust’s organizational documents, its officers andtrustees are indemnified by the Trust against certain liabilitiesarising out of the performance of their duties to the Trust. Additionally, in the normal course of business, the Trust, on behalf of the Funds, enters into contracts with service providers that contain general indemnification clauses. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. Currently, the Trust expects the risk of loss to be remote.

*Effective during the current reporting period, it is no longer required to present certain line items in the Statements of Changes in Net Assets. The below prior period amounts affected by this change are shown as they were in the prior year Statements of Changes in Net Assets.

8. Concentration of Risk

The Funds invest a large percentage of their total assets in securities within similar businesses or sectors. Such concentration may subject the Funds to risks associated with industrial or regional matters, and economic, political or legal developments occurring within the businesses.

Certain or all Funds invest in securities that are restricted under the Securities Act of 1933 (1933 Act). Restricted securities are often purchased in private placement transactions, and cannot be sold without prior registration unless the sale is pursuant to an exemption under the 1933 Act. Disposal of these securities may require greater effort and expense, and prompt sale at an acceptable price may be difficult. The Funds may have registration rights for restricted securities. The issuer generally incurs all registration costs.

11. Credit Facility

The Funds, together with other U.S. registered and foreign investment funds (collectively, Borrowers), managed by Franklin Templeton, are borrowers in a joint syndicated senior unsecured credit facility totaling $2 billion (Global Credit Facility) which matured on February 8, 2019. This Global Credit Facility provides a source of funds to the Borrowers for temporary and emergency purposes, including the ability to meet future unanticipated or unusually large redemption requests. Effective February 8, 2019, the Borrowers renewed the Global Credit Facility for a one year term, maturing February 7, 2020, for a total of $2 billion.

Under the terms of the Global Credit Facility, the Funds shall, in addition to interest charged on any borrowings made by the Funds and other costs incurred by the Funds, pay their share of fees and expenses incurred in connection with the implementation and maintenance of the Global Credit Facility, based upon their relative share of the aggregate net assets of all of the Borrowers, including an annual commitment fee of 0.15% based upon the unused portion of the Global Credit Facility. These fees are reflected in other expenses in the Statements of Operations. During the period ended January 31, 2019, the Funds did not use the Global Credit Facility.

12. Fair Value Measurements

The Funds follow a fair value hierarchy that distinguishes between market data obtained from independent sources (observable inputs) and the Funds’ own market assumptions (unobservable inputs). These inputs are used in determining the value of the Funds’ financial instruments and are summarized in the following fair value hierarchy:

• Level 1 – quoted prices in active markets for identical financial instruments
• Level 2 – other significant observable inputs (including quoted prices for similar financial instruments, interest rates,prepayment speed, credit risk, etc.)
• Level 3 – significant unobservable inputs (including the Funds’ own assumptions in determining the fair value of financialinstruments)

The input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level.

A summary of inputs used as of January 31, 2019, in valuing the Funds’ assets and liabilities carried at fair value, is as follows:
