The Markets in Review

Dear Shareholder,

The last 12 months have been a time of sudden change in global financial markets, as a long period of growth and positive returns was interrupted in early 2020 by the emergence and spread of the coronavirus. For much of the reporting period, U.S. equities and bonds both delivered impressive returns, despite fears and doubts about the economy that were ultimately laid to rest with unprecedented monetary stimulus and a sluggish yet resolute performance from the U.S. economy. But as the threat from the coronavirus became more apparent throughout February and March 2020, leading countries around the world took economically disruptive countermeasures, causing equity prices to fall sharply. While markets have since recovered some of these losses as countries around the world begin reopening, there is still significant uncertainty surrounding the long-term impact of the pandemic on the global economy.

Returns for most securities were robust for the first three quarters of the reporting period, as investors began to realize that the U.S. economy was maintaining the modest yet steady growth that had characterized this economic cycle. However, oncestay-at-home orders and closures ofnon-essential businesses became widespread, many workers were laid off and unemployment claims spiked. With large portions of the global economy on hold, all types of international equities ended the reporting period with negative performance, while in the U.S. only large-capitalization stocks delivered a slightly positive return.

The performance of different types of fixed-income securities diverged substantially due to a reduced investor appetite for risk. Treasuries benefited from therisk-off environment, and posted healthy returns, as the10-year yield (which is inversely related to bond prices) fell to anall-time low. Investment-grade corporate bonds also delivered a positive return, while high-yield corporates were down due to credit concerns.

The U.S. Federal Reserve (the “Fed”) reduced interest rates three times in 2019, to support slowing economic growth. After the coronavirus outbreak, the Fed instituted two emergency rate cuts, pushing short-term interest rates close to zero. To stabilize credit markets, the Fed also announced a new bond-buying program, as did several other central banks around the world, including the European Central Bank and the Bank of Japan.

Looking ahead, while coronavirus-related disruption is certain to hurt worldwide economic growth, the global expansion is likely to continue once the impact of the outbreak subsides. Nonetheless, there are promising signs that a strong coordinated monetary and fiscal response is underway, both in the United States and abroad. With measures being taken to contain the virus and provide support to impacted businesses and individuals, we anticipate a sharp increase in economic activity as life returns to normal.

Overall, we favor a neutral stance toward risk, given the uncertainty surrounding the economic impact of coronavirus countermeasures. Among equities, we see an advantage in U.S. stocks compared to other developed markets, given the diversity of the U.S. economy and the impressive scope of monetary and fiscal stimulus. In bonds, the swift action taken by the world’s central banks means there are attractive opportunities in credit, and we expect credit spreads to narrow as markets stabilize. Both U.S. Treasuries and sustainable investments can help provide portfolio resilience, and the disruption created by the coronavirus appears to be accelerating the shift toward sustainable investments.

In this environment, investors need to think globally, extend their scope across a broad array of asset classes, and be nimble as market conditions change. We encourage you to talk with your financial advisor and visitblackrock.com for further insight about investing in today’s markets.

Sincerely,

Rob Kapito

Money Market Overview  For the6-Month Period Ended April 30, 2020

Notable events over the last six months began with market participants raising awareness regarding slowing global growth amid uncertainties associated with geopolitical events including U.S.-China trade tensions and muted inflation. However, 2019 finished the year with a strong economy, low unemployment and strong returns for U.S. equities. At the onset of 2020, the economy was in a good place and interest rate policy was appropriate according to the Fed, but this outlook quickly changed upon the imposition of dramatic measures by authorities around the world to stem the spread of the coronavirus pandemic. In response, the Fed quickly enacted a series of unprecedented measures to channel credit to businesses and households and smooth market functioning.

The Fed’s stimulus campaign began with an “emergency” 0.50% cut to the Federal Funds target rate on March 3, 2020. This action was followed up a few weeks later with a surprise 1% interest rate cut, bringing the range for the Federal Funds target rate to0.00%-0.25%. This action included a commitment to keep rates low until the uncertainty has passed. Dusting off itscrisis-era playbook, the Fed rebooted or rolled out various support facilities and continues to emphasize its support of credit and liquidity in order to stabilize markets. The most impactful measure for money market funds, in our view, was the creation of the Money Market Liquidity Facility to purchase commercial paper and domestic and Yankee certificates of deposit from prime money market funds, and municipal debt and variable rate demand notes from municipal money market funds.

The facility was largely active and provided liquidity to money market funds by the end of the first quarter of 2020. In a nod to 2008, the Fed revived the following vehicles: the Commercial Paper Funding Facility to backstop the purchase of high-quality commercial paper from U.S. issuers; the Primary Dealer Credit Facility to providelow-cost funding against a broad range of collateral including commercial paper; and the Term Asset Back Securities Lending Facility to purchase asset-backed securities.

Other notable actions included the creation of new facilities to purchase investment-grade corporate debt through the Primary Market Corporate Credit Facility and Secondary Market Corporate Credit Facility. A $2 trillion fiscal aid package signed into law by President Trump along with a series of coordinated global fiscal and monetary actions complemented the Fed’s sweeping measures.

Following its array of monetary stimulus in March, the Federal Open Market Committee (“FOMC”) maintained the0.00%-0.25% range for the Federal Funds target rate at its April 29, 2020 meeting. While no new policy initiatives were announced, the FOMC underscored its recent pledge to use its full gamut of tools to achieve its maximum employment and price stability goals.

The three-month London Interbank Offered Rate overnight-indexed swap spread (a gauge of stress in the financial system) increased from a low of around 0.12% in February to around 1.38% at the end of the first quarter of 2020. While elevated, this measure remains below the 2008 crisis peak of over 3.60%. As markets stabilized in April, this spread ground back toward a level of 0.30% – signaling investor confidence in credits markets. Credit markets in general improved in April as record levels of investment-grade bonds were issued in the market across all tenors, but predominately targeted the longer end of the curve as issuers secured term financing.

Government money market funds were forced to put excess cash to work at or near the “zero lower bound,” while the front end of the Treasury-bill curve was offered at modestly negative rates toward the end of the March quarter. The maximum dailytake-up in the Fed’s reverse repo program — which serves as an investment outlet for eligible money market funds at a rate of 0%-rose sharply to a peak amount of nearly $285 billion at the end of March, the highest level since 2017. Assets of money market funds rose to anall-time high of over $5 trillion, with large government fund inflows offsetting outflows from prime funds.

In our view, we continue to expect the substantial amount of coordinated fiscal and monetary stimulus made available in the United States and abroad to serve as an important bridge in addressing economic and market strains from the drastic measures taken to contain the coronavirus epidemic.Front-end credit markets and prime funds attracted positive flows toward the end of April, and we are optimistic that conditions in the short-term taxable money market could remain favorable given the support of the Fed. While rates in the government space should remain low in absolute terms, historical levels of issuance in Treasury bills over the next quarter could provide modest relief for rates in our opinion.

Turning to short-term municipal bonds, the short-term municipal market ended thesix-month period ended April 30, 2020 at $137.2 billion in assets, down slightly from November 1, 2019. While money fund asset flows were mixed prior to January, record inflows into bond funds and separately managed accounts (“SMAs”) translated into strong demand for variable rate demand note (“VRDN”) securities that were used as temporary investments. As bond issuance came to market, VRDN securities were no longer needed as temporary investments, and VRDN inventory began to increase. However, in January and February of 2020, seasonal-coupon flow into money funds translated into industry assets reaching asix-month high of $141 billion. In addition, bond funds and SMAs continued with their record pace of inflows. The combination translated into persistent demand for VRDN securities as temporary investments and kept downward pressure on the Securities Industry and Financial Markets Association (“SIFMA”) Index, which represents the average yield on weekly VRDNs. As VRDN yields declined, money funds began to experience a slow decline in assets as investors sought higher yielding alternatives.

In March 2020, the impact of the coronavirus pandemic was dramatic and volatile for both markets and investors.Tax-exempt money market funds lost $6 billion in assets as investors redeemed in favor of government money market funds or a preference for actual cash. VRDN inventory on dealer balance sheets spiked to $31 billion, approximately six times the typical carry amount, causing the SIFMA Index to spike to 5.20%. The Fed reacted in a bold way and stated that they would support the economy by doing whatever it takes to combat the growing impact of the coronavirus pandemic on financial markets and economic conditions. The Fed began utilizing a variety of measures to ease the building financial pressures. Measures included lowering the Federal Funds rate by 1.50% to the0.0%-0.25% range and extending asset purchases of bonds and mortgage-backed securities as well as including corporate and municipal bonds. The Fed also activated three Federal programs to relieve balance sheet pressures. These programs have had a dramatic impact in lowering financial market pressures. The resulting elevated VRDN yields garnered increased interest from taxable money funds and crossover accounts during the last week of March, helping to reduce VRDN inventory, which ended the March quarter at $5.2 billion.

In April, withtax-related redemptions pushed back to July 15, VRDN inventory averaged just $2.9 billion, well below historical averages astax-exempt money funds experienced strong inflows, pushing the SIFMA Index to a four-year low of 0.21% before ending the period at 0.22%. Along with downward pressure on VRDN yields, commercial paper, municipal note, and municipal bond yield levels moved sharply lower as well. Theone-year Municipal Market Data yield, which representsone-year municipal bonds, and theone-year MIG1 yield, which represents municipal notes, decreased to end April at 0.81% and 0.80%, respectively.

Looking ahead, seasonal municipal note issuance should begin to ramp up as municipalities address not only their annual operating financing needs, but additional burdens created from the coronavirus pandemic. It remains to be seen how municipal note issuance will be impacted this year given increased state funding needs due to the coronavirus pandemic crisis and the option of using the Fed’s Municipal Liquidity Facility program as a lender of last resort. Municipal money market fund managers are

Disclosure of Expenses

Shareholders of each Fund may incur the following charges: (a) transactional expenses; and (b) operating expenses, including investment advisory fees, service and distribution fees and other fund expenses. The expense examples shown below (which are based on a hypothetical investment of $1,000 invested on November 1, 2019 and held through April 30, 2020, are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds.

The expense examples provide information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their Fund and share class under the heading entitled “Expenses Paid During the Period.”

The expense examples also provide information about hypothetical account values and hypothetical expenses based on a Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in these Funds and other funds, compare the 5% hypothetical examples with the 5% hypothetical examples that appear in shareholder reports of other funds.

The expenses shown in the expense examples are intended to highlight shareholders’ ongoing costs only and do not reflect transactional expenses, such as sales charges, if any. Therefore, the hypothetical examples are useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

1. ORGANIZATION

BlackRock Liquidity Funds (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as anopen-end management investment company. The Trust is organized as a Delaware statutory trust. The following, each of which is a series of the Trust, are referred to herein collectively as the “Funds” or individually as a “Fund”:

Fund Name	Diversification Classification
Federal Trust Fund		Diversified
FedFund		Diversified
TempCash		Diversified
TempFund		Diversified
T-Fund		Diversified
Treasury Trust Fund		Diversified
MuniCash		Diversified
MuniFund		Diversified
California Money Fund		Non-Diversified	(a)
New York Money Fund		Non-Diversified	(a)

(a) California Money Fund and New York Money Fund must satisfy the diversification requirement set forth in Rule2a-7 under the 1940 Act and will thereby be deemed to be diversified under the 1940 Act.

Each Fund offers multiple classes of shares although certain share classes may not be outstanding at the report date. Each Fund offers the following classes of shares: Institutional Shares, Administration Shares, Capital Shares, Cash Management Shares, Cash Reserve Shares, Dollar Shares, Private Client Shares and Select Shares. TempFund,T-Fund, MuniFund, California Money Fund and New York Money Fund also offer Plus Shares. FedFund, TempCash, MuniCash, California Money Fund and New York Money Fund also offer Cash Plus Shares. Except for TempFund, each Fund also offers Premier Shares. For the six months ended April 30, 2020, no Plus Shares or Cash Plus Shares were outstanding. Each Fund offers multiple classes of shares. All classes of shares have identical voting, dividend, liquidation and other rights and are subject to the same terms and conditions, except that certain classes bear expenses related to the shareholder servicing and distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures.

Federal Trust Fund, FedFund,T-Fund and Treasury Trust Fund each operate as a “government money market fund” under Rule2a-7 under the 1940 Act. Each Fund is not subject to liquidity fees or temporary suspensions of redemptions due to declines in a Fund’s weekly liquid assets.

MuniFund operates as a “retail money market fund” under Rule2a-7 under the 1940 Act.

On October 11, 2016, TempCash, TempFund and MuniCash, and on October 15, 2018, California Money Fund and New York Money Fund began pricing and transacting their shares at a net asset value (“NAV”) per share calculated to four decimal places, reflecting market-based values of their portfolio holdings (i.e., at a “floating” NAV). The NAV of TempFund is priced multiple times each day, such Fund accepts purchase orders and redemption requests. Prior to the Funds’ adoption of the floating NAV, their portfolio holdings were valued at amortized cost.

With respect to each of TempCash, TempFund, MuniCash, MuniFund, California Money Fund and New York Money Fund, the Board of Trustees (the “Board”) is permitted to impose a liquidity fee of up to 2% on the value of shares redeemed or temporarily restrict redemptions from TempCash, TempFund, MuniCash, MuniFund, California Money Fund or New York Money Fund for up to 10 business days during a 90 day period, in the event that TempCash, TempFund, MuniCash, MuniFund, California Money Fund or New York Money Fund’s weekly liquid assets fall below certain thresholds.

The Funds, together with certain other registered investment companies advised by BlackRock Advisors, LLC (the “Manager”) or its affiliates, are included in a complex of equity, multi-asset, index and money market funds referred to as the BlackRock Multi-Asset Complex.

2. SIGNIFICANT ACCOUNTING POLICIES

The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. Below is a summary of significant accounting policies:

Investment Transactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed. Realized gains and losses on investment transactions are determined on the identified cost basis. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized on an accrual basis. Income, expenses and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets.

Distributions: Distributions from net investment income are declared daily and paid monthly. Distributions of capital gains are distributed at least annually and are recorded on theex-dividend dates. The character and timing of distributions are determined in accordance with U.S. federal income tax regulations, which may differ from U.S. GAAP.

Liquidity Fees: Any liquidity fees imposed on the value of shares redeemed in the event that TempCash, TempFund, MuniCash, MuniFund, California Money Market Fund or New York Money Market Fund’s weekly liquid assets fall below certain thresholds are recorded aspaid-in-capital. The liquidity fees are collected and retained by each Fund for the benefit of a Fund’s remaining shareholders.

Notes to Financial Statements  (unaudited) (continued)

Recent Accounting Standards: TempCash has adopted Financial Accounting Standards Board Accounting Standards Update2017-08 to amend the amortization period for certain purchased callable debt securities held at a premium. Under the new standard, TempCash has changed the amortization period for the premium on certain purchased callable debt securities withnon-contingent call features to the earliest call date. In accordance with the transition provisions of the standard, TempCash applied the amendments on a modified retrospective basis beginning with the fiscal period ended April 30, 2020. The adjusted cost basis of securities at October 31, 2019 is $9,786,855,817.

This change in accounting policy has been made to comply with the newly issued accounting standard and had no impact on accumulated earnings (loss) or the net asset value of TempCash.

Indemnifications: In the normal course of business, a Fund enters into contracts that contain a variety of representations that provide general indemnification. A Fund’s maximum exposure under these arrangements is unknown because it involves future potential claims against a Fund, which cannot be predicted with any certainty.

Other: Expenses directly related to a Fund or its classes are charged to that Fund or the applicable class. Other operating expenses shared by several funds, including other funds managed by the Manager, are prorated among those funds on the basis of relative net assets or other appropriate methods. Expenses directly related to the Funds and other shared expenses prorated to the Funds are allocated daily to each class based on their relative net assets or other appropriate methods.

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

Investment Valuation Policies (TempCash, TempFund, MuniCash, California Money Fund and New York Money Fund): TempCash, MuniCash, California Money Fund and New York Money Funds’ investments are valued at fair value (also referred to as “market value” within the financial statements) as of 3:00 p.m., Eastern time, on each day on which the New York Stock Exchange (“NYSE”) is open for business. TempFund’s investments are valued at fair value (also referred to as “market value” within the financial statements) as of 8:00 a.m. (Eastern time), 12:00 p.m. (Eastern time) and 3:00 p.m. (Eastern time) on each day on which the NYSE is open for business. U.S. GAAP defines fair value as the price the Funds would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Funds determine the fair values of their financial instruments using various independent dealers or pricing services under policies approved by the Board. If a security’s market price is not readily available or does not otherwise accurately represent the fair value of the security, the security will be valued in accordance with a policy approved by the Board as reflecting fair value. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to oversee the pricing function for all financial instruments.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of TempCash, TempFund, MuniCash, California Money Fund and New York Money Funds’ assets and liabilities:

• Investments are valued on the basis of prices provided by dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments and information with respect to various relationships between investments.

• Fixed-income securities for which market quotations are readily available are generally valued using the last available bid prices or current market quotations provided by independent dealers or third party pricing services. Floating rate loan interests are valued at the mean of the bid prices from one or more independent brokers or dealers as obtained from a third party pricing service. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent representative bids and offers), credit quality information, perceived market movements, news, and other relevant information. Certain fixed-income securities, including asset-backed and mortgage related securities may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless the Manager determines such method does not represent fair value.

• Municipal investments (including commitments to purchase such investments on a “when-issued” basis) are valued on the basis of prices provided by dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments and information with respect to various relationships between investments.

Investment Valuation Policies (Federal Trust Fund, FedFund,T-Fund, Treasury Trust Fund and MuniFund): U.S. GAAP defines fair value as the price the Funds would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Funds’ investments are valued under the amortized cost method which approximates current market value in accordance with Rule2a-7 under the 1940 Act. Under this method, investments are valued at cost when purchased and, thereafter, a constant proportionate accretion of discounts and amortization of premiums are recorded until the maturity of the security. Each Fund seeks to maintain its NAV per share at $1.00, although there is no assurance that it will be able to do so on a continuing basis.

Fair Value Hierarchy: Various inputs are used in determining the fair value of investments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial statement purposes as follows:

• Level 1 — Unadjusted price quotations in active markets/exchanges for identical assets or liabilities that each Fund has the ability to access

• Level 2 — Other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market–corroborated inputs)

• Level 3 — Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Global Valuation Committee’s assumptions used in determining the fair value of investments)

NOTESTO FINANCIAL STATEMENTS 127

Notes to Financial Statements  (unaudited) (continued)

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The categorization of a value determined for investments is based on the pricing transparency of the investments and is not necessarily an indication of the risks associated with investing in those securities.

4. SECURITIES AND OTHER INVESTMENTS

Repurchase Agreements: Repurchase agreements are commitments to purchase a security from a counterparty who agrees to repurchase the same security at a mutually agreed upon date and price. On a daily basis, the counterparty is required to maintain eligible collateral subject to the agreement and in value no less than the agreed upon repurchase amount. Repurchase agreements may be traded bilaterally, in atri-party arrangement or may be centrally cleared through a sponsoring agent. Subject to the custodial undertaking associated with atri-party repurchase arrangement and for centrally cleared repurchase agreements, a third party custodian maintains accounts to hold collateral for a fund and its counterparties. Typically, a fund and counterparty are not permitted to sell,re-pledge or use the collateral absent a default by the counterparty or a fund, respectively. Certain Funds, along with other registered investment companies advised by the Manager, may transfer uninvested cash into a single joint trading account which is then invested in one or more repurchase agreements. As of period end, FedFund, TempCash, TempFund andT-Fund invested in repurchase agreements through joint trading accounts.

In the event the counterparty defaults and the fair value of the collateral declines, a fund could experience losses, delays and costs in liquidating the collateral.

Repurchase agreements are entered into by a fund under Master Repurchase Agreements (each, an “MRA”). The MRA permits a fund, under certain circumstances including an event of default (such as bankruptcy or insolvency), to offset payables and/or receivables with collateral held by and/or posted to the counterparty. As a result, one single net payment is created. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of the MRA counterparty’s bankruptcy or insolvency. Based on the terms of the MRA, a fund receives securities as collateral with a market value in excess of the repurchase price at maturity. Upon a bankruptcy or insolvency of the MRA counterparty, a fund would recognize a liability with respect to such excess collateral. The liability reflects a fund’s obligation under bankruptcy law to return the excess to the counterparty.

5. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Service and Distribution Fees: The Trust, on behalf of the Funds, entered into a separate Distribution Agreement, Distribution Plans and Shareholder Service Plans with BlackRock Investments, LLC (“BRIL”), an affiliate of BlackRock. Pursuant to the Select Shares Distribution Plan and the Private Client Shares Distribution Plan, the Trust may pay BRIL a fee for distribution and sales support services. In addition, the Trust may pay service organizations, including affiliates of the Manager, fees for providing certain services (“shareholder services”) to their customers who own shares of the Funds. Pursuant to its respective Shareholder Services Plan, each of the Administration, Capital, Cash Management, Cash Reserve, Dollar, Private Client and Select Share classes are currently paying fees to service organizations, which may include affiliates of the Manager. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows:

	Service Fees(a)			Distribution Fees(a)
Administration		0.10	%		—	%
Capital		0.05			—
Cash Management		0.50			—
Cash Reserve		0.40			—

For these services, these entities receive an asset-based fee or an annual fee per shareholder account, which will vary depending on share class and/or net assets. For the six months ended April 30, 2020, the Funds did not pay any amounts to affiliates in return for these services.

Expense Limitations, Waivers and Reimbursements: With respect to each Fund, the Manager, as investment adviser and administrator, has contractually agreed to reduce its fees and/or reimburse ordinary operating expenses to ensure that the combined “Management Fees” and “Miscellaneous/Other Expenses,” excluding service fees, distribution fees and any extraordinary expenses, do not exceed 0.18% of the average daily net assets of TempCash and TempFund, 0.17% of the average daily net assets of FedFund,T-Fund, Federal Trust Fund and Treasury Trust Fund and 0.20% of the average daily net assets of MuniCash, MuniFund, California Money Fund and New York Money Fund. Any fees waived by the Manager with respect to a particular fiscal year are not recoverable. The Manager has agreed not to reduce or discontinue these contractual expense limitations prior to March 1, 2021, unless approved by the Board, including a majority of the trustees who are not “interested persons” of the Trust, as defined in the 1940 Act (“Independent Trustees”), or by a vote of a majority of the outstanding voting securities of such Fund. These amounts are included in fees waived and/or reimbursed by the Manager in the Statements of Operations. For the six months ended April 30, 2020, the amounts waived were as follows:

Interfund Lending: In accordance with an exemptive order (the “Order”) from the U.S. Securities and Exchange Commission (“SEC”) each Fund may participate in a joint lending and borrowing facility for temporary purposes (the “Interfund Lending Program”), subject to compliance with the terms and conditions of the Order, and to the extent permitted by each Fund’s investment policies and restrictions. Each Fund is currently permitted to borrow under the Interfund Lending Program.

A lending BlackRock fund may lend in aggregate up to 15% of its net assets, but may not lend more than 5% of its net assets to any one borrowing fund through the Interfund Lending Program. A borrowing BlackRock fund may not borrow through the Interfund Lending Program or from any other source more than 33 1/3% of its total assets (or any lower threshold provided for by the fund’s investment restrictions). If a borrowing BlackRock fund’s total outstanding borrowings exceed 10% of its total assets, each of its outstanding interfund loans will be subject to collateralization of at least 102% of the outstanding principal value of the loan. All interfund loans are for temporary or emergency purposes and the interest rate to be charged will be the average of the highest current overnight repurchase agreement rate available to a lending fund and the bank loan rate, as calculated according to a formula established by the Board.

During the period ended April 30, 2020, the Funds did not participate in the Interfund Lending Program.

Trustees and Officers:Certain trustees and/or officers of the Trust are directors and/or officers of BlackRock or its affiliates. The Funds reimburse the Manager for a portion of the compensation paid to the Funds’ Chief Compliance Officer, which is included in Trustees and Officer in the Statements of Operations.

Other Transactions: During the six months ended April 30, 2020, TempFund received a reimbursement of $14,497 from an affiliate, which is included in payment by affiliate in the Statements of Operations, related to an operating event.

The Funds may purchase securities from, or sell securities to, an affiliated fund provided the affiliation is due solely to having a common investment adviser, common officers, or common trustees. For the six months ended April 30, 2020, the purchase and sale transactions and any net realized gains (losses) with affiliated funds in compliance with Rule17a-7 under the 1940 Act were as follows:

6. INCOME TAX INFORMATION

It is each Fund’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute substantially all of its taxable income to its shareholders. Therefore, no U.S. federal income tax provision is required.

Each Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on each Fund’s U.S. federal tax returns generally remains open for each of the four years ended October 31, 2019. The statutes of limitations on each Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to the Funds as of April 30, 2020, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

As of October 31, 2019, the Funds hadnon-expiring capital loss carryforwards available to offset future realized capital gains as follows:

	Non-Expiring Capital Loss Carryforward
MuniCash	$	55,451
MuniFund		3,026
California Money Fund		41

As of April 30, 2020, gross unrealized appreciation and depreciation for investments based on cost for U.S. federal income tax purposes were as follows:

	TempCash
Tax cost	$	7,743,233,134
Gross unrealized appreciation	$	5,849,240
Gross unrealized depreciation		(1,330,384	)
Net unrealized appreciation	$	4,518,856

7. PRINCIPAL RISKS

Many municipalities insure repayment of their bonds, which may reduce the potential for loss due to credit risk. The market value of these bonds may fluctuate for other reasons, including market perception of the value of such insurance, and there is no guarantee that the insurer will meet its obligation.

Inventories of municipal bonds held by brokers and dealers may decrease, which would lessen their ability to make a market in these securities. Such a reduction in market making capacity could potentially decrease a Fund’s ability to buy or sell bonds. As a result, a Fund may sell a security at a lower price, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative impact on performance. If a Fund needed to sell large blocks of bonds, those sales could further reduce the bonds’ prices and impact performance.

In the normal course of business, certain Funds invest in securities or other instruments and may enter into certain transactions and such activities subject each Fund to various risks, including among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate and price fluctuations. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Funds and their investments. Each Fund’s prospectus provides details of the risks to which each Fund is subject.

Each Fund may be exposed to prepayment risk, which is the risk that borrowers may exercise their option to prepay principal earlier than scheduled during periods of declining interest rates, which would force each Fund to reinvest in lower yielding securities. Each Fund may also be exposed to reinvestment risk, which is the risk that income from each Fund’s portfolio will decline if each Fund invests the proceeds from matured, traded or called fixed-income securities at market interest rates that are below each Fund portfolio’s current earnings rate.

Certain obligations held by the Funds have a credit enhancement or liquidity feature that may, under certain circumstances, provide for repayment of principal and interest on the obligation when due. These enhancements, which may include letters of credit,stand-by bond purchase agreements and/or third party insurance, are issued by financial institutions. The value of the obligations may be affected by changes in creditworthiness of the entities that provide the credit enhancements or liquidity features. The Funds

NOTESTO FINANCIAL STATEMENTS 131

Notes to Financial Statements  (unaudited) (continued)

monitor their exposure by reviewing the creditworthiness of the issuers, as well as the financial institutions issuing the credit enhancements and by limiting the amount of holdings with credit enhancements from one financial institution.

An outbreak of respiratory disease caused by a novel coronavirus has developed into a global pandemic and has resulted in closing borders, quarantines, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this pandemic, and other global health crises that may arise in the future, could affect the economies of many nations, individual companies and the market in general in ways that cannot necessarily be foreseen at the present time. This pandemic may result in substantial market volatility and may adversely impact the prices and liquidity of a Fund’s investments. The impact of the pandemic may be short term or may last for an extended period of time.

Counterparty Credit Risk: The Funds may be exposed to counterparty credit risk, or the risk that an entity may fail to or be unable to perform on its commitments related to unsettled or open transactions. The Funds manage counterparty credit risk by entering into transactions only with counterparties that the Manager believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Funds to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Funds’ exposure to market, issuer and counterparty credit risks with respect to these financial assets is approximately their value recorded in the Statements of Assets and Liabilities, less any collateral held by the Funds.

Concentration Risk: MuniFund, California Money Fund and New York Money Fund invest a substantial amount of their assets in issuers located in a single state or limited number of states. This may subject each Fund to the risk that economic, political or social issues impacting a particular state or group of states could have an adverse and disproportionate impact on the income from, or the value or liquidity of, the Funds’ respective portfolios. Investment percentages in specific states or U.S. territories are presented in the Schedules of Investments.

Certain Funds invest a significant portion of their assets in fixed-income securities and/or use derivatives tied to the fixed-income markets. Changes in market interest rates or economic conditions may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Funds may be subject to a greater risk of rising interest rates due to the current period of historically low rates.

8. CAPITAL SHARE TRANSACTIONS

The Trust’s Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest (shares) and to classify or reclassify any unissued shares into one or more additional classes of shares.

The number of shares sold, reinvested and redeemed corresponds to the net proceeds from the sale of shares, reinvestment of all distributions and cost of shares redeemed, respectively, since shares are sold and redeemed at $1.00 per share for Federal Trust Fund, FedFund,T-Fund, Treasury Trust Fund and MuniFund.
