The Markets in Review

Dear Shareholder,

Diverging monetary policies and shifting economic outlooks across regions have been the overarching themes driving financial markets over the past couple of years. Investors spent most of 2015 anticipating the end of the Federal Reserve’s (the “Fed”) near-zero interest rate policy as U.S. growth outpaced other developed markets. The Fed ultimately hiked rates in December, whereas the European Central Bank and the Bank of Japan took additional steps to stimulate growth, even introducing negative interest rates. The U.S. dollar had strengthened considerably ahead of these developments, causing profit challenges for U.S. companies that generate revenues overseas, and pressuring emerging market currencies and commodities prices.

Global market volatility increased in the latter part of 2015 and spilled over into early 2016. Oil prices were a key factor behind the instability after collapsing in mid-2015 due to excess global supply. China, one of the world’s largest consumers of oil, was another notable source of stress for financial markets. Signs of slowing economic growth, a depreciating yuan and declining confidence in the country’s policymakers stoked investors’ worries about the potential impact of China’s weakness on the global economy.

Fears of a global recession started to fade toward the end of the first quarter of 2016 and volatility abated. Central bank stimulus in Europe and Japan, combined with a more tempered outlook for rate hikes in the United States, helped bolster financial markets. A softening in U.S. dollar strength offered some relief to U.S. exporters and emerging market economies. Oil prices found firmer footing as global supply showed signs of leveling off.

The selloff in risk assets at the turn of the year has resulted in more reasonable valuations and some appealing entry points for investors today. However, investors continue to face the headwinds of uncertainty around China’s growth trajectory and currency management, the potential consequences of negative interest rates and geopolitical risks.

For the 12 months ended March 31, 2016, higher-quality assets such as municipal bonds, U.S. Treasuries and investment grade corporate bonds generated positive returns, while riskier assets such as non-U.S. and small cap equities broadly declined.

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

Sincerely,

Rob Kapito

Money Market Overview

For the 12-Month Period Ended March 31, 2016

The Federal Open Market Committee (the “Committee”) left rates unchanged at the March 16, 2016 meeting, which was not surprising in our opinion given low expectations for a rate increase on the heels of market turmoil earlier in the year. Indeed, the Committee continued to highlight concern about risks associated with global financial and economic developments, and downshifted its expectations for the pace of normalization. The Committee’s present forecast envisions two rate hikes of 25 basis points (0.25%) each during the balance of 2016, down from a projected four increases as of its December 16, 2015 meeting. A stronger-than-expected February employment report combined with recent upward pressure on the Core Personal Consumption Expenditures Index — the Committee’s preferred measure of inflation — suggest that it may not be overly optimistic to anticipate that conditions will ultimately line up behind at least one rate hike, possibly as soon as June. While not our base case, a number of Committee members even intimated that an increase in rates as soon as April was not out of the question. In our view, the fact that inflation has been running behind the Committee’s target for nearly four years reinforces a gradual approach to policy normalization.

While the Committee’s recent statement was generally perceived as “dovish,” anxiety about the prospect of negative interest rates seems to have diminished somewhat. At the post-meeting press conference, Chairwoman Yellen stated that the Committee is “not actively considering negative rates,” supporting our belief that the odds of such a development are relatively narrow.

The slope of the short-dated London Interbank Offered Rate (“LIBOR”) curve steepened in March in response to continued uncertainty about the path of interest rates and the possible shift of additional assets from prime to government money market funds later in the year. We would anticipate a continuation of this trend in the months ahead.

4 BBIF TAX-EXEMPT FUND MARCH 31, 2016

Fund Information as of March 31, 2016

Investment Objective

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

On February 18, 2016, the Board of Trustees of the Fund approved a proposal to close the Fund to purchases and thereafter to liquidate the Fund. Accordingly, effective on July 11, 2016, the Fund will no longer accept purchases orders. On or about July 15, 2016 (the “Liquidation Date”), all of the assets of the Fund will be liquidated completely, the shares outstanding on the Liquidation Date will be redeemed at the net asset value per share and the Fund will then be terminated.

Current Seven-Day Yields

	7-Day SEC Yields	7-Day Yields
Class 1	0.00%		0.00	%
Class 2	0.00%		0.00	%
Class 3	0.00%		0.00	%
Class 4	0.00%		0.00	%

The 7-Day SEC Yields may differ from the 7-Day Yields shown above due to the fact that the 7-Day SEC Yields exclude 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, acquired fund fees and expenses, and other Fund expenses. The expense example shown below (which is based on a hypothetical investment of $1,000 invested on October 1, 2015 and held through March 31, 2016) 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 corresponding to their share class 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 shareholder reports of other funds.

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 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.

Expense Example

	Actual						Hypothetical2						Annualized Expense Ratio
	Beginning Account Value October 1, 2015		Ending Account Value March 31, 2016		Expenses Paid During the Period1		Beginning Account Value October 1, 2015		Ending Account Value March 31, 2016		Expenses Paid During the Period1
Class 1	$	1,000.00	$	1,000.00	$	0.50	$	1,000.00	$	1,024.50	$	0.51		0.10	%
Class 2	$	1,000.00	$	1,000.00	$	0.50	$	1,000.00	$	1,024.50	$	0.51		0.10	%
Class 3	$	1,000.00	$	1,000.00	$	0.50	$	1,000.00	$	1,024.50	$	0.51		0.10	%
Class 4	$	1,000.00	$	1,000.00	$	0.50	$	1,000.00	$	1,024.50	$	0.51		0.10	%

¹  For each class of the Fund, expenses are equal to the annualized net expense ratio for the class, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period shown). Because the Fund invests all of its assets in Master Tax-Exempt LLC (the “Master LLC”), the expense examples reflect the net expenses of both the Fund and the Master LLC in which it invests.

²  Hypothetical 5% annual return before expenses is calculated by prorating the number of days in the most recent fiscal half year divided by 366.

Notes to Financial Statements BBIF Tax-Exempt Fund

1. Organization:

BBIF 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. At period end, the percentage of the Master LLC owned by the Fund was 13.6%. 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 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 each bears certain expenses related to shareholder servicing and expenses related to the distribution of such shares. Class 1, Class 2, Class 3 and Class 4 Shares are only available through exchanges and distribution reinvestments by current holders and for purchase by certain employer-sponsored retirement plans. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures. The Board of Trustees of the Fund and Board of Directors of the Master LLC are referred to throughout this report as the “Board of Directors” or the “Board” and the members are referred to as “Directors.”

On February 18, 2016, the Board approved a proposal to close the Fund to purchases and thereafter to liquidate the Fund. Accordingly, effective on July 11, 2016, the Fund will no longer accept purchases orders. On or about July 15, 2016 (the “Liquidation Date”), all of the assets of the Fund will be liquidated completely, the shares outstanding on the Liquidation Date will be redeemed at the net asset value per share and the Fund will then be terminated.

The Fund, together with certain other registered investment companies advised by BlackRock Advisors, LLC (the “Administrator”) or its affiliates, is included in a complex of open-end funds referred to as the Equity-Liquidity 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. The 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 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 expenses. 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 and reinvested daily. Distributions of capital gains are distributed at least annually and are recorded on the ex-dividend date. The character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

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

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

The Fund may earn interest 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 income in the Statement of Operations.

Notes to Financial Statements (continued) BBIF Tax-Exempt Fund

3. Investment Valuation and Fair Value Measurements:

Investment Valuation Policies: The Fund’s policy is to fair value its financial instruments at market value. 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 3 of the Master LLC’s Notes to Financial Statements, which are included elsewhere in this report.

4. Administration Agreement and Other Transactions with Affiliates:

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

Administration

The Fund entered into an Administration Agreement with 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.

Service and Distribution Fees

The Fund entered into a Distribution Agreement and Distribution Plans with BlackRock Investments, LLC (“BRIL”), an affiliate of the Administrator. Pursuant to the Distribution 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 annual rates based upon the average daily net assets of the relevant share class of the Fund as follows:

	Class 1		Class 2		Class 3		Class 4
Service Fee		0.25%		0.25%		0.25%		0.25%
Distribution Fee		0.750%		0.425%		0.125%		0.125%

Pursuant to sub-agreements with BRIL, broker-dealers and BRIL provide shareholder servicing and distribution services to the Fund. The ongoing service and/or distribution fee compensates BRIL and each broker-dealer for providing shareholder servicing and/or distribution related services to the shareholders.

For the year ended March 31, 2016, the following table shows the class specific service and distribution fees borne directly by each share class of the Fund:

Class 1		Class 2		Class 3		Class 4		Total
$	184,738	$	207,711	$	436,352	$	824,489	$	1,653,290

Transfer Agent

For the year ended March 31, 2016, the following table shows the class specific transfer agent fees borne directly by each class of the Fund:

Class 1		Class 2		Class 3		Class 4		Total
$	7,139	$	3,478	$	4,881	$	11,007	$	26,505

Expense Limitations, Waivers and Reimbursements

The Fund entered into a contractual arrangement with the Administrator and BRIL to waive and/or reimburse a portion of the Fund’s direct fees and expenses, which excludes fees and expenses allocated from the Master LLC, to ensure that the net expenses for the Fund’s Class 2 Shares are 0.35% higher than those of BIF Tax-Exempt Fund, and the net expenses for the Fund’s Class 3 and Class 4 Shares are equal to those of BIF Tax-Exempt Fund, without giving effect to any voluntary fee waivers. The fee/expense waiver includes service and distribution fees. The Administrator and BRIL have agreed not to reduce or discontinue this contractual waiver or reimbursement prior to August 1, 2017. This contractual agreement may be terminated upon 90 days’ notice by a majority of the non-interested Directors or by a vote of a majority of the outstanding voting securities of the Fund. These amounts are included in service and distribution fees waived — class specific in the Statement of Operations.

For the year ended March 31, 2016, the amounts included in service and distribution fees waived – class specific were as follows:

Class 1		Class 2		Class 3		Class 4		Total
$	184,738	$	207,711	$	436,352	$	824,489	$	1,653,290

14 BBIF TAX-EXEMPT FUND MARCH 31, 2016

Notes to Financial Statements (continued) BBIF Tax-Exempt Fund

The Administrator and BRIL voluntarily agreed to waive a portion of the investment advisory fee and/or 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 the Administrator. The Administrator and BRIL may discontinue the waiver or reimbursement at any time.

For the year ended March 31, 2016, the amounts included in transfer agent fees reimbursed – class specific were as follows:

Class 1		Class 2		Class 3		Class 4		Total
$	7,139	$	3,478	$	4,881	$	11,007	$	26,505

For the year ended March 31, 2016, the amounts included in other expenses waived and/or reimbursed by the Administrator– class specific were as follows:

Class 1		Class 2		Class 3		Class 4		Total
$	3,425	$	5,721	$	21,623	$	41,238	$	72,007

Officers and Directors

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.

5. Income Tax Information:

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, 2016. 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 as of March 31, 2016, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

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. As of period end, the following permanent differences attributable to the use of equalization were reclassified to the following accounts:

Paid-in capital	$	29,945
Accumulated net realized gain allocated from the Master LLC	$	(29,945	)

The tax character of distributions paid was as follows:

	3/31/16			3/31/15
Tax-exempt income1	$	325		$	374
Ordinary income2		4,369	4		23,874
Long-term capital gains3		26,904	4		17,994
Total	$	31,598		$	42,242

¹  The Fund designates this amount paid during the fiscal year ended March 31, 2016 as exempt-interest dividends.

²  Ordinary income consists primarily of taxable income recognized from net short-term capital gains. Additionally, all ordinary distributions are comprised of qualified short-term capital gain dividends for non-U.S. residents and are eligible for exemption from U.S. withholding tax for nonresident aliens and foreign corporations.

³  The Fund designates this amount paid during the fiscal year ended March 31, 2016 as capital gain dividends.

⁴  Distribution amounts may include a portion of the proceeds from redeemed shares.

As of period end, the tax components of accumulated net earnings (losses) were as follows:

Undistributed tax-exempt income	$	261
Undistributed ordinary income		3,551
Undistributed long-term capital gains		20,837
Total	$	24,649

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

6. Principal Risks:

On July 23, 2014, the U.S. Securities and Exchange Commission adopted amendments to money market fund regulations, which structurally change the way that certain money market funds will be required to operate. The compliance periods for the amendments range between July 2015 and October 2016. The changes may affect a money market fund’s investment strategies, fees and expenses, portfolio and share liquidity and return potential.

7. Capital Share Transactions:

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.

Transactions in capital shares for each class were as follows:

	Year Ended March 31, 2016			Year Ended March 31, 2015
Class 1
Shares sold		194,667,882			319,091,667

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying statement of assets and liabilities of BBIF Tax-Exempt Fund (the “Fund”) as of March 31, 2016, 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 BBIF Tax-Exempt Fund as of March 31, 2016, 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.

The accompanying financial statements have been prepared assuming that the Fund will continue as a going concern. As discussed in Note 1 to the financial statements, the Board of the Fund approved a proposal to close the Fund to new investors and thereafter to liquidate the Fund. Management’s plans concerning these matters are also discussed in Note 1 to the financial statements. The financial statements do not include any adjustments that might result from the liquidation event.

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.

The Master LLC, together with certain other registered investment companies advised by BlackRock Advisors, LLC (the “Manager”) or its affiliates, is included in a complex of open-end funds referred to as the Equity-Liquidity 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. The Master LLC 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 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.

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

Other: Expenses directly related to the Master LLC are charged to the Master LLC. 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.

The Master LLC has an arrangement with its 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. Effective October 2015, the custodian is imposing fees on certain uninvested cash balances.

3. Investment Valuation and Fair Value Measurements:

Investment Valuation Policies: 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. The Master LLC seeks to maintain its net asset value 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 the Master LLC 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 Master LLC’s own assumptions used in determining the fair value of investments)

30 BBIF TAX-EXEMPT FUND MARCH 31, 2016

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

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 fair value hierarchy for the Master LLC’s investments has been included in the Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the hierarchy. In accordance with the Master LLC’s policy, transfers between different levels of the fair value 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 investments and is not necessarily an indication of the risks associated with investing in those securities.

4. Investment Advisory Agreement and Other Transactions with Affiliates:

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

Investment Advisory

The Master LLC entered into an Investment Advisory Agreement with 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 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 rates:

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

Waivers and Reimbursements

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

For the year ended March 31, 2016, the Master LLC reimbursed the Manager $31,416 for certain accounting services, which is included in accounting services in the Statement of Operations.

Officers and Directors

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

Other Transactions

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 advisor, common officers, or common directors. For the year ended March 31, 2016, the purchase and sale transactions with an affiliated fund in compliance with Rule 17a-7 under the 1940 Act were $681,001,283 and $456,630,124, respectively.

5. Income Tax Information:

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, 2016. 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.

BBIF TAX-EXEMPT FUND MARCH 31, 2016 31

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

Management has analyzed tax laws and regulations and their application to the Master LLC as of March 31, 2016, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Master LLC’s financial statements.

6. Principal Risks:

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 to meet all its obligations, including the ability to pay principal and interest when due (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 of securities owned by the Master LLC. Changes arising from the general economy, the overall market and local, regional or global political and/or social instability, as well as currency, interest rate and price fluctuations, may also affect the securities’ value.

Certain obligations held by the 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.

On July 23, 2014, the U.S. Securities and Exchange Commission adopted amendments to money market fund regulations, which structurally change the way that certain money market funds will be required to operate. The compliance periods for the amendments range between July 2015 and October 2016. The changes may affect a money market fund’s investment strategies, fees and expenses, portfolio and share liquidity and return potential.

Counterparty Credit Risk: Similar to issuer credit risk, the Master LLC 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 Master LLC manages 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 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 approximately their value recorded in the Statement of Assets and Liabilities, less any collateral held by the Master LLC.

7. Subsequent Events:

Management’s evaluation of the impact of all subsequent events on the Master LLC’s financial statements was completed through the date the financial statements were issued and the following items were noted:

On May 19, 2016, the Board approved a proposal to liquidate the Master LLC. Accordingly, on or about July 15, 2016, (the “Liquidation Date”), all of the assets of the Master LLC will be liquidated completely, the interests of any interestholders on the Liquidation Date will be redeemed and the Master LLC will then be terminated.

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, 2016, 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, 2016, 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, 2016, 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.

The accompanying financial statements have been prepared assuming that the Master LLC will continue as a going concern. As discussed in Note 7 to the financial statements, the Board of the Master LLC approved a proposal to close the Master LLC to new investors and thereafter to liquidate the Master LLC. Management’s plans concerning this matter is also discussed in Note 7 to the financial statements. The financial statements do not include any adjustments that might result from the liquidation event.

(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

2

by the registrant’s Committee. The Committee also must approve other non-audit services provided to the registrant 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

	(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.
