2 BIF TAX-EXEMPT FUND MARCH 31, 2014

Shareholder Letter

Dear Shareholder,

One year ago, U.S. financial markets were improving despite a sluggish global economy, as easy monetary policy provided investors with enough conviction to take on more risk in their portfolios. Slow but positive growth in the U.S. was sufficient to support corporate earnings, while uncomfortably high unemployment reinforced expectations that the Federal Reserve would continue to maintain its aggressive monetary stimulus programs.

Sentiment swiftly reversed in May when then-Fed Chairman Bernanke first mentioned the possibility of reducing (or “tapering”) the central bank’s asset purchase programs — comments that were widely misinterpreted as signaling an end to the Fed’s zero-interest-rate policy. U.S. Treasury yields rose sharply, triggering a steep sell-off across fixed income markets. (Bond prices move in the opposite direction of yields.) Global equities also suffered as investors feared the implications of a potential end to a program that had greatly supported the markets. Emerging markets, which are more sensitive to changes in global liquidity, were particularly hurt by the prospect of ebbing cash flows from the U.S. Markets rebounded in late June, however, when the Fed’s tone turned more dovish, and improving economic indicators and better corporate earnings helped extend gains through most of the summer.

Although the tone of economic and financial news was mixed during the autumn, it was a surprisingly positive period for most asset classes. Early on, the Fed defied market expectations with its decision to delay tapering, but higher volatility returned in late September when the U.S. Treasury Department warned that the national debt would soon breach its statutory maximum. The ensuing political brinksmanship led to a partial government shutdown, roiling global financial markets through the first half of October. Equities and other so-called “risk assets” managed to resume their rally when politicians engineered a compromise to reopen the government and extend the debt ceiling.

The remainder of 2013 was generally positive for stock markets in the developed world, although investors continued to grapple with uncertainty about when and how much the Fed would scale back on stimulus. When the Fed ultimately announced its tapering plans in mid-December, markets reacted positively, as this action signaled the Fed’s perception of real improvement in the economy, and investors were finally relieved from the anxiety that had gripped them for quite some time.

The start of the new year brought another turn in sentiment, as heightened risks in emerging markets and mixed U.S. economic data caused global equities to weaken in January while bond markets found renewed strength. Although these headwinds persisted, equities were back on the rise in February as investors were encouraged by a one-year extension of the U.S. debt ceiling and market-friendly comments from the Fed’s new Chairwoman, Janet Yellen. While U.S. economic data pointed to softer growth, investors viewed this trend as temporarily driven by poor winter weather and continued adding risk to their portfolios on the belief that growth would pick up in the coming months. In March, markets focused on decelerating growth in China and tensions between Russia and Ukraine over the disputed region of Crimea. Additionally, investors were caught off guard by a statement from Chairwoman Yellen indicating that the Fed may raise short-term interest rates earlier than the markets had previously forecasted. Bond markets came under pressure as the middle of the yield curve vaulted higher in response to the unexpected shift in forward guidance.

Against a backdrop of modest economic growth, investors over the past year remained highly attuned to potential changes in monetary policy. Despite the fact that markets were gearing up for a modest shift toward tighter conditions from the Fed, equity markets in the developed world generated strong returns for the six- and 12-month periods ended March 31, with stocks in the United States performing particularly well. In contrast, emerging markets were weighed down by concerns about reduced global liquidity, severe currency weakness, high levels of debt and uneven growth.

Interest rate uncertainty posed a headwind for fixed income assets, and higher-quality sectors of the market experienced heightened volatility and poor performance over the reporting period. High yield bonds, however, benefited from income-oriented investors’ search for yield in the overall low-rate environment. Short-term interest rates remained near zero, keeping yields on money market securities close to historic lows.

At BlackRock, we believe investors need to think globally, extend their scope across a broad array of asset classes and be prepared to move freely as market conditions change over time. We encourage you to talk with your financial advisor and visit www.blackrock.com for further insight about investing in today’s world.

  In a modest global growth environment, expectations around monetary policy changes continued to be a key theme in financial market performance.

Money Market Overview

For the 12 Month Period Ended March 31, 2014

Against a backdrop of continued moderate economic growth, low inflation and persistently high unemployment, the Federal Open Market Committee (“FOMC”) maintained its target range for the federal funds rate at 0.00% to 0.25% during the 12-month period ended March 31, 2014. After buying securities at a pace of $85 billion per month over the previous year, the FOMC altered course in December 2013. Citing the “cumulative progress toward maximum employment and the improvement in the outlook for labor market conditions,” the FOMC announced it would begin reducing the pace of its monthly purchases by $10 billion to a rate of $75 billion per month, beginning in January 2014. The FOMC held to this new course in 2014, paring its monthly purchases by an additional $10 billion at its regular meetings in January and March. Janet L. Yellen replaced Ben Bernanke as the Chair of the Board of Governors of the Federal Reserve in February. Yellen, who acted as vice chair under Bernanke, is expected to follow his approach of maintaining low short-term rates while continuing to reduce the FOMC’s monthly bond purchases at a measured pace.

In Europe, sub-par growth and a weak inflation environment compelled policymakers to employ an increasingly accommodative monetary policy throughout the period. Early in the second quarter of 2013, the eurozone was grappling with the aftermath of a severe banking crisis in Cyprus. Financial markets normalized when European and Cypriot officials ultimately agreed upon a controversial plan to impose a levy on bank depositors as a condition for the country to preserve its membership in the euro currency bloc. In September, the currency bloc received a crucial vote of confidence with the decisive re-election of Chancellor Angela Merkel in Germany as this was seen as an endorsement by German voters of her strong support of the euro. Ongoing efforts from the European Central Bank (“ECB”) to resuscitate the eurozone economy with record-low interest rates met only limited success in lifting growth measures. At the same time, inflation measures drifted lower, falling to 0.7% in October, less than half the ECB’s target rate. These conditions prompted the ECB to cut its main refinancing rate to 0.25% from 0.50% in November. Since then, ECB President Mario Draghi has repeatedly suggested that the central bank is ready to act aggressively if needed; thus far, however, the ECB has refrained from taking any further actions to stimulate the eurozone economy.

Late in the third quarter, the U.S. Federal Reserve introduced a fixed-rate reverse repurchase agreement (“repo”) facility in which select counterparties can lend U.S. dollars overnight to the Fed. Over the following six months, the Fed increased the maximum bid per counterparty from the initial amount of $500 million to $7 billion and increased the offered rate from 0.01% to 0.05%. Usage of this facility increased gradually to an average of $86 billion per day during the month of March. On March 31st, the facility generated a record one-day total of $242 billion in repo transactions as dealers reduced their inventories and collateral in the repo market became scarce.

London Interbank Offered Rates (“LIBOR”) notched lower over the 12 months due in large part to central bank liquidity measures, coupled with decreasing supply in the money market space. Benchmark three-month LIBOR fell by 0.05% to end the period at 0.23% — a historic low amid commercial banks extending to longer maturity dates or shifting funding needs away from the short-term wholesale markets. Other short-term rates, including U.S. Treasury bills, ground lower over the period as demand continued to outweigh supply. Yields on 3-month U.S. Treasury bills declined from 0.06% over the 12-month period to 0.03% as of March 31st. U.S. Treasury bills outstanding declined by $139 billion as the federal budget deficit improved and the U.S. Treasury cut the size of its weekly bill auctions to make room in its auction schedule to issue two-year floating rate notes (“FRNs”) — the first new structure issued in almost 17 years. FRN issuance totaled $41 billion in the first quarter of 2014. Much of the void resulting from the decline in supply has been filled with utilization of the Fed’s fixed-rate reverse repo facility, which has proven very popular with investors, particularly at calendar quarter-ends. A fully operational facility is expected to figure prominently in eventual decisions by policymakers to raise interest rates.

In the short-term tax-exempt market, conditions remained stable for yet another year as tax-exempt money fund industry assets declined by only 1.0% over the 12-month period to $269 billion as of March 31, 2014. The benchmark Securities Industry and Financial Markets Association (“SIFMA”) Index, which represents the average rate on seven-day, high-quality, tax-exempt variable rate demand notes (“VRDNs”) (as calculated by Municipal Market Data) ranged between a high of 0.23% and an all-time low of 0.03%, averaging 0.08% for the 12-month period. The sustained downward pressure on SIFMA Index levels is a reflection of the increasing prevalence of non-traditional buyers in the market and the continued demand by money market funds which saw a stabilization in assets over the past two years.

Although Janet Yellen has been installed as the new Chair of the Federal Reserve, the policy of easy money has not changed. This has kept rates on taxable overnight repos low by historical measures. Given the low levels on taxable repos, tax-exempt VRDNs remain attractive as an alternative investment for taxable money funds. This cross over demand, coupled with the natural demand from tax-exempt money funds, has placed undue pressure on VRDN yields as evidenced by the prolonged low levels of the SIFMA Index.

April 15th brings the annual tax season, during which tax-exempt money funds typically experience large outflows due to shareholders redeeming shares to pay their federal and state income tax bills. Tax season rolls into “note season” in June, when municipalities typically issue one-year tax and revenue anticipation notes. Given continued austerity measures at state and local municipalities, spending has been limited as well as the need for debt issuance. As such, supply of new-issue, one-year fixed-rate notes has diminished. Generally speaking, municipal money market funds tend to take advantage of note season to extend their weighted average maturity, pick up yield and diversify beyond bank exposure in the form of credit enhancement. This year, we expect investor demand for one-year notes will be stronger than in previous years. Given expectations that the end of the FOMC’s current monetary policy is on the horizon, issuers may need to offer greater yield premiums to entice buyers to extend out to the full year maturity, thereby steepening the yield curve.

Fund Information as of March 31, 2014

Investment Objective

BIF Tax-Exempt Fund’s (the “Fund”) investment objective is to seek current income exempt from federal income tax, preservation of capital and liquidity.

Current Seven-Day Yields

	7-Day SEC Yield			7-Day Yield
BIF Tax-Exempt Fund		0.00	%		0.00	%

The 7-Day SEC Yield may differ from the 7-Day Yield shown above due to the fact that the 7-Day SEC Yield excludes distributed capital gains. Past performance is not indicative of future results.

Disclosure of Expenses

Shareholders of the Fund may incur the following charges: (a) transactional expenses, such as sales charges; and (b) operating expenses, including administration fees, service and distribution fees, including 12b-1 fees, and other Fund expenses. The expense example shown below (which is based on a hypothetical investment of $1,000 invested on October 1, 2013 and held through March 31, 2014) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds.

The expense example provides 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 under the heading entitled “Expenses Paid During the Period.”

The expense example also provides information 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. In order to assist shareholders in comparing the ongoing expenses of investing in the Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds’ shareholder reports.

The expenses shown in the expense example are intended to highlight shareholders’ ongoing costs only and do not reflect any transactional expenses, such as sales charges, if any. Therefore, the hypothetical example is 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  Expenses are equal to the Fund’s annualized net expense ratio, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). Because the Fund is a feeder fund, the expense example reflects the net expenses of both the Fund and the master fund in which it invests.

²  Hypothetical 5% annual return before expenses is calculated by pro rating the number of days in the most recent fiscal half year divided by 365.

Notes to Financial Statements BIF Tax-Exempt Fund

1. Organization:

BIF Tax-Exempt Fund (the “Fund”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, open-end management investment company. The Fund is organized as a Massachusetts business trust. The Fund seeks to achieve its investment objective by investing all of its assets in Master Tax-Exempt LLC (the “Master LLC”), an affiliate of the Fund, which has the same investment objective and strategies as the Fund. The value of the Fund’s investment in the Master LLC reflects the Fund’s proportionate interest in the net assets of the Master LLC. The performance of the Fund is directly affected by the performance of the Master LLC. The percentage of the Master LLC owned by the Fund at March 31, 2014 was 88.6%. As such, the financial statements of the Master LLC, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund’s financial statements. The Board of Trustees of the Fund and the Board of Directors of the Master LLC are referred to throughout the report as the “Board of Directors” or the “Board” and the members are referred to as “Directors”.

2. Significant Accounting Policies:

The Fund’s 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 and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund:

Valuation: U.S. GAAP defines fair value as the price the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Fund records its investment in the Master LLC at fair value based on the Fund’s proportionate interest in the net assets of the Master LLC. Valuation of securities held by the Master LLC is discussed in Note 2 of the Master LLC’s Notes to Financial Statements, which are included elsewhere in this report. The Fund seeks to maintain its net asset value per share at $1.00, although there is no assurance that they will be able to do so on a continuing basis.

Investment Transactions and Investment Income: For financial reporting purposes, contributions to and withdrawals from the Master LLC are accounted on a trade date basis. The Fund records daily its proportionate share of the Master LLC’s income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own income and expenses.

Dividends and Distributions: Dividends from net investment income are declared and paid daily. Distributions of capital gains are recorded on the ex-dividend date. The character and timing of dividends and distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Income Taxes: It is the 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 federal income tax provision is required.

The 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 the Fund’s U.S. federal tax returns remains open for each of the four years ended March 31, 2014. The statutes of limitations on the 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 Fund’s facts and circumstances and does not believe there are any uncertain tax positions that require recognition of a tax liability.

Other: Expenses directly related to the Fund are charged to the Fund. Other operating expenses shared by several funds are pro rated among those funds on the basis of relative net assets or other appropriate methods.

The Fund may earn income on positive cash balances in demand deposit accounts that are maintained by the transfer agent on behalf of the Fund. This amount, if any, is shown as interest in the Statements of Operations.

3. Administration Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. is the largest stockholder and an affiliate, for 1940 Act purposes of, BlackRock, Inc. (“BlackRock”).

The Fund entered into an Administration Agreement with BlackRock Advisors, LLC (the “Administrator”), an indirect, wholly owned subsidiary of BlackRock, to provide administrative services (other than investment advice and related portfolio activities). For such services, the Fund pays the Administrator a monthly fee at an annual rate of 0.25% of the average daily value of the Fund’s net assets. The Fund does not pay an investment advisory fee or investment management fee.

The Fund entered into a Distribution Agreement and a Distribution and Service Plan with BlackRock Investments, LLC (“BRIL”), an affiliate of BlackRock. Pursuant to the Distribution and Service Plan and in accordance with Rule 12b-1 under the 1940 Act, the Fund pays BRIL ongoing service and distribution fees. The fees are accrued daily and paid monthly at the annual rate of 0.125% based upon the average daily net assets of the fund.

Pursuant to sub-agreements with BRIL, broker-dealers and BRIL provide shareholder servicing and distribution services to the Fund. The ongoing

BIF TAX-EXEMPT FUND MARCH 31, 2014 9

Notes to Financial Statements (concluded) BIF Tax-Exempt Fund

service and/or distribution fee compensates BRIL and each broker-dealer for providing shareholder servicing and/or distribution related services.

The Administrator and BRIL voluntarily agreed to waive administration and service fees and reimburse operating expenses to enable the Fund to maintain minimum levels of daily net investment income. These amounts are reported in the Statement of Operations as fees waived by administrator or service and distribution fees waived. The Administrator and BRIL may discontinue the waiver or reimbursement at any time.

Certain officers and/or directors of the Fund are officers and/or directors of BlackRock or its affiliates. The Fund reimburses the Administrator for a portion of the compensation paid to the Fund’s Chief Compliance Officer, which is included in officer in the Statement of Operations.

4. Income Tax Information:

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. The following permanent difference as of March 31, 2014 attributable to the characterization of investment income for tax purposes was reclassified to the following accounts:

10 BIF TAX-EXEMPT FUND MARCH 31, 2014

Report of Independent Registered Public Accounting Firm BIF Tax-Exempt Fund

To the Shareholders and Board of Trustees of BIF Tax-Exempt Fund:

We have audited the accompanying statement of assets and liabilities of BIF Tax-Exempt Fund (the “Fund”) as of March 31, 2014, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of BIF Tax-Exempt Fund as of March 31, 2014, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

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

Ÿ Level 1 — unadjusted price quotations in active markets/exchanges for identical assets or liabilities that the Master LLC has the ability to access

Ÿ 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)

Ÿ Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Master LLC’s own assumptions used in determining the fair value of investments)

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.

Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. In accordance with the Master LLC’s policy, transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of a value determined for investments is based on the pricing transparency of the investment and is not necessarily an indication of the risks associated with investing in those securities. For information about the Master LLC’s policy regarding valuation of investments, please refer to Note 2 of the Notes to Financial Statements.

The following table summarizes the Master LLC’s investments categorized in the disclosure hierarchy as of March 31, 2014:

	Level 1	Level 2	Level 3	Total
Assets:
Investments:
Municipal Bonds1	—	$2,833,177,160	—	$2,833,177,160
1   See above Schedule of Investments for values in each state or political subdivision.

The carrying amount for certain of the Master LLC’s assets approximates fair value for financial statement purposes. As of March 31, 2014, cash of $856,917 is categorized as Level 1 within the disclosure hierarchy.

There were no transfers between levels during the year ended March 31, 2014.

24	BIF TAX-EXEMPT FUND	MARCH 31, 2014

Notes to Financial Statements Master Tax-Exempt LLC

1. Organization:

Master Tax-Exempt LLC (the “Master LLC”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and is organized as a Delaware limited liability company. The Master LLC’s Limited Liability Company Agreement permits the Board of Directors of the Master LLC (the “Board”) to issue non-transferable interests in the Master LLC, subject to certain limitations.

2. Significant Accounting Policies:

The Master LLC’s 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 and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Master LLC:

Valuation: U.S. GAAP defines fair value as the price the Master LLC would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Master LLC’s investments are valued under the amortized cost method which approximates current market value in accordance with Rule 2a-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.

Investment Transactions and Investment Income: For financial reporting purposes, investment transactions are recorded on the dates the transactions are entered into (the trade dates). 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 the accrual basis.

Income Taxes: The Master LLC is classified as a partnership for federal income tax purposes. As such, each investor in the Master LLC is treated as the owner of its proportionate share of net assets, income, expenses and realized and unrealized gains and losses of the Master LLC. Therefore, no federal income tax provision is required. It is intended that the Master LLC’s assets will be managed so an investor in the Master LLC can satisfy the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended.

The Master LLC files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Master LLC’s U.S. federal tax returns remains open for each of the four years ended March 31, 2014. The statutes of limitations on the Master LLC’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 Master LLC’s facts and circumstances and does not believe there are any uncertain tax positions that require recognition of a tax liability.

Other: Expenses directly related to the Master LLC are charged to the Master LLC. Other operating expenses shared by several funds are pro rated among those funds on the basis of relative net assets or other appropriate methods.

The Master LLC has an arrangement with the custodian whereby fees may be reduced by credits earned on uninvested cash balances, which, if applicable, are shown as fees paid indirectly in the Statement of Operations. The custodian imposes fees on overdrawn cash balances, which can be offset by accumulated credits earned or may result in additional custody charges.

3. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. is the largest stockholder and an affiliate, for 1940 Act purposes, of BlackRock, Inc. (“BlackRock”).

The Master LLC entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Master LLC’s investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services. The Manager is responsible for the management of the Master LLC’s portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Master LLC. For such services, the Master LLC pays the Manager a monthly fee based on a percentage of the Master LLC’s average daily net assets at the following annual rate:

Average Daily Net Assets	Investment Advisory Fee
First $500 Million		0.250	%
$500 Million — $1 Billion		0.175	%
Greater than $1 Billion		0.125	%

The Manager entered into a sub-advisory agreement with BlackRock Investment Management, LLC (“BIM”), an affiliate of the Manager. The Manager pays BIM, for services it provides, a monthly fee that is a percentage of the investment advisory fees paid by the Master LLC to the Manager.

The Manager voluntarily agreed to waive a portion of the advisory fees and/or reimburse operating expenses of the Master LLC to enable the feeder funds that invest in the Master LLC to maintain minimum levels of net investment income. These amounts, if any, are reported in the Statement of Operations as fees waived by Manager.

For the year ended March 31, 2014, the Master LLC reimbursed the Manager $29,866 for certain accounting services, which is included in accounting services in the Statement of Operations.

BIF TAX-EXEMPT FUND MARCH 31, 2014 25

Notes to Financial Statements (concluded) Master Tax-Exempt LLC

Certain officers and/or directors of the Master LLC are officers and/or directors of BlackRock or its affiliates.

The Master LLC 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 year ended March 31, 2014, the purchase and sale transactions with an affiliated fund in compliance with Rule 17a-7 under the 1940 Act were $617,017,898 and $228,206,640, respectively.

4. Market and Credit Risk:

In the normal course of business, the Master LLC invests in securities and enters into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (issuer credit risk). The value of securities held by the Master LLC may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Master LLC; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to issuer credit risk, the Master LLC may be exposed to counterparty credit risk, or the risk that an entity with which the Master LLC has unsettled or open transactions may fail to or be unable to perform on its commitments. The Master LLC manages counterparty credit risk by entering into transactions only with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Master LLC to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Master LLC’s exposure to market, issuer and counterparty credit risks with respect to these financial assets is generally approximated by their value recorded in the Statement of Assets and Liabilities, less any collateral held by the Master LLC.

Certain obligations held by the Master LLC 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 Master LLC monitors its 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.

5. Subsequent Events:

Management has evaluated the impact of all subsequent events on the Master LLC through the date the financial statements were issued and has determined that there were no subsequent events requiring adjustment or additional disclosure in the financial statements.

Report of Independent Registered Public Accounting Firm Master Tax-Exempt LLC

To the Investors and Board of Directors of Master Tax-Exempt LLC:

We have audited the accompanying statement of assets and liabilities of Master Tax-Exempt LLC (the “Master LLC”), including the schedule of investments, as of March 31, 2014, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Master LLC’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Master LLC is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Master LLC’s internal control over financial reporting. Accordingly, we express no such opinion.

An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 2014, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Master Tax-Exempt LLC as of March 31, 2014, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

Each Committee has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the registrant’s Committee. The Committee also must approve other non-audit services provided to the registrant

2

and those non-audit services provided to the Investment Adviser and Fund Service Providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are (a) consistent with the SEC’s auditor independence rules and (b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis (“general pre-approval”). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrants which have a direct impact on the operations or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 per project. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the registrant’s Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to the Committee Chairman the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by either Committee pursuant to the de minimus exception in paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) The aggregate non-audit fees paid to the accountant for services rendered by the accountant to the registrant, the Investment Adviser and the Fund Service Providers were:

Entity Name	Current Fiscal Year  End	Previous Fiscal Year End
BIF Tax-Exempt Fund	$10,600	$10,600

	(h) Each Committee has considered and determined that the provision of non-audit services that were rendered to the Investment Adviser and the Fund Service Providers that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.
