The Markets in Review

Dear Member,

This report reflects your Fund’s reporting period ended March 31, 2015. The following review is intended to provide you with additional market perspective over the past 12 months.

Market volatility has remained low from a long-term perspective, but increased over the course of 2014 amid higher valuations in risk assets (such as equities and high yield bonds), geopolitical risks, uneven global economic growth and uncertainty around policy moves from the world’s largest central banks. As the U.S. Federal Reserve (the “Fed”) gradually reduced its bond buying program (which ultimately ended in October 2014), U.S. interest rates surprisingly trended lower and stock prices forged ahead despite high valuations on the back of a multi-year bull market. Geopolitical tensions intensified in Ukraine and the Middle East and oil prices became highly volatile in the middle of the summer, stoking worries about economic growth outside the United States. As the U.S. economy continued to show steady improvement, the stronger data caused concern among investors that the Fed would raise short-term rates sooner than previously anticipated. The U.S. dollar appreciated and global credit markets tightened, ultimately putting a strain on investor flows, and financial markets broadly weakened in the third quarter.

U.S. economic growth picked up considerably in the fourth quarter while the broader global economy showed signs of slowing. U.S. markets significantly outperformed international markets even as the European Central Bank (“ECB”) and the Bank of Japan eased monetary policy, which drove further strengthening in the U.S. dollar. Oil prices plummeted in the fourth quarter due to a global supply-and-demand imbalance, sparking a selloff in energy-related assets and stress in emerging markets. Fixed income investors piled into U.S. Treasuries as their persistently low yields became relatively attractive as compared to international sovereign debt.

Equity markets reversed in the first quarter of 2015 and U.S. stocks underperformed international markets, notably Europe and Japan, but also emerging markets. Investors had held high expectations for the U.S. economy, but after a harsh winter, first-quarter data disappointed and high valuations took their toll on U.S. stocks. Meanwhile, economic reports in Europe and Asia easily beat investors’ very low expectations for those economies, and accommodative policies from global central banks helped international equities rebound. The ECB’s asset purchase program (announced in January and commenced in March) was the largest in scale and effect on the markets. Overall, market volatility decreased in the first quarter as global risks abated, with a ceasefire in Ukraine and an improving outlook for Greece’s continued membership in the Eurozone.

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 blackrock.com for further insight about investing in today’s markets.

Sincerely,

Rob Kapito

Fund Summary as of March 31, 2015

Fund Overview

BlackRock Preferred Partners LLC’s (the “Fund”) investment objective is to seek total return. Over an investment cycle, the Fund expects to achieve net returns commensurate with the long-term return on equities with less volatility and a relatively low degree of correlation to the equity markets. The Fund seeks to achieve its investment objective by investing directly or indirectly in private funds or other pooled investment vehicles or accounts organized outside the United States (“Portfolio Funds”) generally believed not to be highly correlated with the Standard & Poor’s 500 Index over a long-term horizon. The Fund may also invest directly in securities (other than those of Portfolio Funds) or other financial instruments.

No assurance can be given that the Fund’s investment objective will be achieved.

Portfolio Management Commentary

How did the Fund perform?

Ÿ For the 12-month period ended March 31, 2015, the Fund returned 4.51% based on net asset value. For the same period, the Fund’s benchmark, the HFRI Fund of Funds Composite Index, returned 5.39%.

Underlying Fund Strategies

Ÿ The Fund invests in a portfolio of hedge funds as a means to gain exposure to various types of investment strategies in five major categories including fundamental long/short, relative value, event-driven, directional trading and direct sourcing strategies.

Ÿ Fundamental long/short strategies involve buying or selling predominantly corporate securities believed to be over- or underpriced relative to their potential value. Investment strategies in this category include long and short equity- or credit-based strategies, which emphasize a fundamental valuation framework, and equity active value strategies, where an active role is taken to enhance corporate value.

Ÿ Relative value strategies seek to profit from the mispricing of financial instruments relative to each other or historical norms. These strategies utilize quantitative and qualitative analyses to identify securities or spreads between securities that deviate from their theoretical fair value and/or historical norms.

Ÿ Event-driven strategies concentrate on companies that are subject to corporate events such as mergers, acquisitions, restructurings, spin-offs, shareholder activism or other special situations that alter a company’s financial structure or operating strategy. The intended goal of these strategies is to profit when the price of a security changes to reflect more accurately the likelihood and potential impact of the occurrence, or non-occurrence, of the event.

Ÿ Directional trading strategies seek to profit in changes from macro-level exposures, such as broad securities markets, interest rates, exchange rates and commodities. Examples include global macro strategies that express macroeconomic views based on analysis of fundamental factors and managed futures strategies, which select futures instruments based typically on systematic technical analysis.

Ÿ Direct sourcing strategies seek to garner profits from areas of the market that are underserved by traditional financial institutions by entering into direct transactions to provide financing to institutions or individuals. Typically, these strategies rely on a manager’s ability to source or access privately structured deals as well as fundamental research specific to each respective deal.

What factors influenced performance?

Ÿ The Fund’s exposure to directional trading strategies made the largest contribution to positive performance during the period. The strategies capitalized on increased technical and directional trading opportunities, particularly during the latter half of the period.

Ÿ Fundamental long/short strategies were the second-largest contributor to the Fund’s performance, with equity selection and credit strategies adding value within the category. Exposure to a number of event-driven strategies that benefited from increased corporate activity, such as reorganizations, post-reorganizational activity, mergers and bankruptcies, also had a positive impact on performance.

Ÿ The Fund’s exposure to relative value strategies detracted from performance.

Describe recent portfolio activity.

Ÿ The Fund added Blue Harbour Strategic Value Partners Offshore, Ltd. (Fundamental Long/Short), Hitchwood Capital Fund, Ltd. (Fundamental Long/Short), Pine River Liquid Rates Fund, Ltd. (Relative Value) and Stratus Feeder LP (Relative Value). The Fund also redeemed Alphabet Offshore, Ltd. (Relative Value), Brigade Leveraged Capital Structures Offshore, Ltd. (Fundamental Long/Short) and Claren Road Credit Fund, Ltd. (Fundamental Long/Short).

Ÿ In the aggregate, the Fund’s position changes resulted in increased exposure to fundamental long/short and directional trading strategies and slight decreases in exposure to relative value and direct sourcing strategies.

Describe portfolio positioning at period end.

Ÿ At period end, the Fund held broad exposure across a spectrum of different hedge fund strategies. For purposes of financial reporting, the underlying hedge funds are categorized based on their primary underlying strategy exposure. In this regard, the categories of investment strategies as a percentage of the Fund’s long term investments are 37% fundamental long/short strategies, 24% relative value, 21% event driven and 18% directional trading.

Ÿ However, notwithstanding their categorization for financial reporting purposes, many of these hedge funds provide exposure to multiple types of underlying strategies. Based on such underlying strategy exposures, the Fund held 45% of its investments in fundamental long/short, 21% in relative value, 17% in event driven, 16% in directional trading and 1% in direct sourcing strategies.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Total Return Based on a $50,000 Investment

¹  Assuming maximum sales charges, if any, transaction costs and other operating expenses, including investment advisory fees.

²  Under normal market conditions, the Fund will invest, in varying proportions, across a number of portfolio strategies, including but not limited to hedge fund strategies and cash strategies. The Fund may also invest directly in securities (other than those of Portfolio Funds) or other financial instruments selected by the Advisor.

³  This index represents funds of hedge funds that invest with multiple hedge fund managers focused on absolute return strategies. This equal-weighted index includes funds of hedge funds tracked by Hedge Fund Research Inc. and is revised several times each month to reflect updated hedge fund return information. For performance presented as of any given month, estimated values of underlying funds are used to build the index until valuations are finalized (generally on a 5-month lag although the time period may vary). This index is a proxy for the performance of the universe of funds of hedge funds focused on absolute return strategies. Returns are net of fees.

About Fund Performance

BlackRock Preferred Partners LLC Units incur a maximum initial sales charge of 3.00%, an annual distribution fee of 0.75% and an annual management fee of 0.75%.

Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Performance results do not reflect the deduction of taxes that a Member would pay on Fund distributions or the repurchase of Fund Units. A 2.00% early repurchase fee payable to the Fund may be charged to a member that tenders its Units to the Fund in connection with a tender offer with a valuation date that is prior to the one-year anniversary of the member’s purchase of the respective Units. This early repurchase fee would apply separately to each purchase of Units made by a member. The purpose of the 2.00% early repurchase fee is to reimburse the Fund for the costs incurred in liquidating investments in the Fund’s portfolio in order to honor the member’s repurchase request and to discourage short-term investments which are generally

disruptive to the Fund’s investment program. The Fund may, in its sole discretion, waive the early repurchase fee under certain circumstances described in the Fund’s prospectus. Performance data does not reflect this potential fee. Figures shown in the performance table assume reinvestment of all distributions, if any, at net asset value on the payable date. Investment return and the principal value of Units will fluctuate so that Units, when and if repurchased pursuant to a tender offer, may be worth more or less than their original cost.

The Fund’s investment advisor, BlackRock Advisors LLC (the “Advisor”), waived and/or reimbursed a portion of the Fund’s expenses during the periods described above. Without such waiver and/or reimbursement, the Fund’s performance would have been lower.

See “General Information” at the end of this report for where additional information can be obtained.

Disclosure of Expenses for Continuously Offered Closed-End Funds

Members of the Fund may incur the following charges: (a) transactional expenses, such as sales charges and early repurchase fees; and (b) operating expenses, including investment advisory fees, distribution fees, and other Fund expenses. The expense example shown below (which is based on a hypothetical investment of $1,000 invested on October 1, 2014 and held through March 31, 2015) is intended to assist members both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other funds.

The expense example provides information about actual account values and actual expenses. In order to estimate the expenses a member paid during the period covered by this report, members 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, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. In order to assist members 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 member reports of other funds.

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

²  Expenses are equal to the annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). Annualized expense ratio does not include expenses incurred indirectly as a result of investments in Portfolio Funds.

³  Hypothetical 5% annual return before expenses is calculated by prorating the number of days in the most recent fiscal half year divided by 365.

Notes to Schedule of Investments

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. 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 investment and is not necessarily an indication of the risks associated with investing in those securities. The three levels of the fair value hierarchy are as follows:

Ÿ Level 1 — unadjusted quoted prices in active markets/exchanges for identical assets or liabilities that the Fund 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). If the reporting entity has the ability to redeem its investment with the Portfolio Funds at the net asset value per share (or its equivalent) at the measurement date or within the near term and there are no other liquidity restrictions, the Fund’s investment in the Portfolio Fund will be considered
Level 2.

Ÿ Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments). Investments in Portfolio Funds that are currently subject to liquidity restrictions that will not be lifted in the near term will be considered Level 3.

The Fund’s investments in Portfolio Funds not otherwise traded on an active exchange are classified within Level 2 or Level 3 of the fair value hierarchy as the value of these interests are primarily based on the respective net asset value reported by management of each Portfolio Fund rather than actual market transactions and other observable market data. The determination of whether such investment will be classified in Level 2 or Level 3 will be based upon the ability to redeem such investment within a reasonable period of time (within 90 days of the period end and any other month-end). If an investment in a Portfolio Fund may be redeemed within 90 days of the period end and any other month-end, and the fair value of the investment is based on information provided by management of the Portfolio Funds and has not been adjusted by BlackRock Advisors LLC, it is classified as Level 2; in all other cases it is classified as Level 3. Changes in redemption features may result in transfers into or out of an assigned level within the disclosure hierarchy. For information about the Fund’s policy regarding valuation of investments, refer to Note 2 of the Notes to Financial Statements.

As of March 31, 2015, the following table summarizes the Fund’s investments categorized in the disclosure hierarchy:

	Level 1	Level 2		Level 3		Total

¹  In determining the classification of investments in Portfolio Funds included in the table above, no consideration was given to the classification of securities held by each underlying Portfolio Fund.

The Fund may hold assets in which the fair value approximates the carrying amount for financial statement purposes. As of March 31, 2015, cash of $2,347,145 is categorized as Level 1 within the disclosure hierarchy.

During the year ended March 31, 2015, there were no transfers between Level 1 and Level 2.

¹  As of March 31, 2014, certain investments were subject to liquidity restrictions that would not be lifted in the near term. As of March 31, 2015, these liquidity restrictions were lifted for these investments. As a result, as of March 31, 2015 investments with a beginning of year value of $11,176,377 transferred from Level 3 to Level 2 in the disclosure hierarchy.

²  Included in the related net change in unrealized appreciation/depreciation in the Statement of Operations.

³  Any difference between Net change in unrealized appreciation/depreciation and Net change in unrealized appreciation/depreciation on investments still held at March 31, 2015 is generally due to investments no longer held or categorized as Level 3 at period end.

Notes to Financial Statements

1. Organization:

BlackRock Preferred Partners LLC (the “Fund”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”) as a continuously offered, non-diversified, closed-end management investment company. The Fund is organized as a Delaware limited liability company. The Fund continuously offers one class of limited liability company interests (“Units”), which may be sold to certain eligible investors with a front-end sales charge of up to 3.00%.

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 members’ capital 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: The Fund’s investments are valued at fair value as of the close of trading on the New York Stock Exchange (“NYSE”) (generally 4:00 p.m., Eastern time). 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 Board has adopted and approved written policies and procedures (the “Valuation Procedures”) for the purpose of determining the value of securities held by the Fund, including the fair value of the Fund’s investments in interests in private funds or other pooled investment vehicles (collectively the “Portfolio Funds”), and has delegated to the internal valuation committee of the Advisor and its registered investment advisory affiliates (the “Global Valuation Committee”) the responsibility for the day-to-day oversight of the valuation of the Fund’s investments pursuant to the Valuation Procedures. The Fund will invest in Portfolio Funds selected by and unaffiliated with BlackRock Advisors, LLC (the “Advisor”), an indirect wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”).

In valuing interests in Portfolio Funds, the Advisor, under the supervision of the Fund’s Board of Directors (the “Board”), considers all relevant information to determine the price that the Fund might reasonably expect to receive from the current sale (or redemption in the case of a Portfolio Fund whose interests carry redemption rights) of the interest in the Portfolio Fund in an arm’s-length transaction. In general, the Advisor will rely primarily on any actual or estimated (as applicable) unaudited values provided by the Portfolio Fund manager to the extent such unaudited values are received in a timely fashion and are believed to be the most reliable and relevant indication of the value of interests in such Portfolio Fund. It is anticipated that these unaudited values will be prepared in accordance with U.S. GAAP and will, in effect, be the fair value of each Portfolio Fund’s assets, less such Portfolio Fund’s liabilities (the net asset value). In some cases, estimated unaudited values are provided before final unaudited values. The Advisor will rely primarily on such estimated unaudited values or final unaudited values, to the extent they are the most reliable and relevant indication of value of interests in the Portfolio Funds. The Advisor will give weight to such valuations and any other factors and considerations set forth in the Valuation Procedures as deemed appropriate in each case. The Fund will only invest in Portfolio Funds that comply with U.S. GAAP and that provide annual audited financial statements. In general, the Advisor will, prior to investing in any Portfolio Fund, and periodically thereafter, assess such Portfolio Fund’s valuation policies and procedures for appropriateness in light of the Fund’s obligation to fair value its assets under the 1940 Act and pursuant to U.S. GAAP for investment companies and will assess the overall reasonableness of the information provided by such Portfolio Fund. As part of this assessment, the Advisor may also evaluate, among other things, a Portfolio Fund’s practices in respect of creating “side pockets” and such Portfolio Fund’s valuation policies and procedures in respect of any such “side pockets.” The Advisor will also review any other information available to it, including reports by independent auditors, fund administrators, if any, and/or other third parties.

In instances where unaudited estimated or final values may not be available, or where such unaudited estimated or final values are determined not to be the most reliable and relevant indication of value of an interest in a Portfolio Fund (as further discussed below), additional factors that may be relevant in determining the value of an interest in a Portfolio Fund, in addition to those other factors and considerations set forth in the Valuation Procedures, include (1) changes in the valuation of hedge fund indices, (2) publicly available information regarding a Portfolio Fund’s underlying portfolio companies or investments, (3) the price at which recent subscriptions and redemptions of such Portfolio Fund interests were offered, (4) relevant news and other sources, (5) significant market events and (6) information provided to the Advisor or the Fund by a Portfolio Fund, or the failure to provide such information as agreed to in the Portfolio Fund’s offering materials or other agreements with the Fund.

In circumstances where, taking into account the factors and considerations set forth above and in the Valuation Procedures, the Advisor has reason to believe that a value provided by a Portfolio Fund is not the most reliable and relevant indication of the value of an interest in the Portfolio Fund, the Advisor may adjust such reported value to reflect the fair value of the interest in the Portfolio Fund. Likewise, in circumstances where a Portfolio Fund does not provide a valuation as contemplated above, the factors and considerations set forth above and in the Valuation Procedures may be the only indicators of the value of an interest in a Portfolio Fund and the Advisor will use such factors, together with other valuation methodologies set forth in the Valuation Procedures that may be relevant, to estimate the fair value of its interest in a Portfolio Fund. In circumstances where the Advisor determines to adjust the values reported by Portfolio Funds, or in circumstances where the Portfolio Funds do not provide valuations as contemplated above

BLACKROCK PREFERRED PARTNERS LLC MARCH 31, 2015 15

Notes to Financial Statements (continued)

(such circumstances being collectively referred to as “Adjusted Fair Values”), such valuations will be subject to review and approval by the Global Valuation Committee or its delegate as outlined in the Valuation Procedures. The Board reviews all fair value determinations at its regularly scheduled meetings and also reviews the Valuation Procedures on a regular basis. As of March 31, 2015, the Advisor did not adjust any values received for the Portfolio Funds.

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. Dividend income is recorded on the ex-dividend date.

Distributions: Distributions from net investment income and capital gains are declared and paid annually. The character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Recent Accounting Standard: In April 2015, the Financial Accounting Standards Board issued “Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share” which eliminates the requirement to categorize investments within the fair value hierarchy for which fair value is based on the NAV per share when no quoted market value is available. The new guidance will also require revised disclosures regarding these investments. The guidance is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. Management is evaluating the impact of this guidance on the Fund’s financial statement disclosures.

Other: Expenses directly related to the Fund are charged to the Fund. Other operating expenses shared by several funds are prorated among those funds on the basis of relative members’ capital or other appropriate methods.

The Fund 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.

3. Investments in Portfolio Funds:

Information reflecting the Fund’s investments in Portfolio Funds as of March 31, 2015 is summarized below. The Fund is not able to obtain complete investment holding details of each of the Portfolio Funds held within the Fund’s portfolio in order to determine whether the Fund’s proportionate share of any investments held by a Portfolio Fund exceeds 5% of the members’ capital of the Fund as of March 31, 2015.

* Primary Geographic Locations is based upon information of which the Fund is aware regarding the geographic allocations of the investments held by the Portfolio Funds in which the Fund invests. The Fund does not have sufficient portfolio holdings information with respect to the Portfolio Funds to monitor such positions on a look through basis. The information regarding the geographic allocation of investments held by the Portfolio Funds is derived from periodic information provided to the Fund by the managers of such Portfolio Funds. The information in this table represents only information that has been made available to the Fund with respect to investments held by the Portfolio Funds as of March 31, 2015. This information has not been independently verified by the Fund and may not be representative of the current geographic allocation of investments held by the Portfolio Funds since such Portfolio Funds are actively managed and this information is generally provided by the Portfolio Funds on a delayed basis after the date of such information.

** Redemptions Permitted reflects general redemption terms for each Portfolio Fund and excludes any temporary liquidity restrictions.

BLACKROCK PREFERRED PARTNERS LLC MARCH 31, 2015 17

Notes to Financial Statements (continued)

The agreements related to investments in Portfolio Funds provide for compensation to the investment managers/general partners of such Portfolio Funds in the form of management fees generally ranging from 1% to 3% (per annum) of members’ capital and incentive fees/allocations generally ranging from 15% to 25% of the net profits earned. The Portfolio Funds’ management fees and incentive fees/allocations are included in net change in unrealized appreciation/depreciation on investments in the Statement of Operations.

The table below summarizes the fair value and other pertinent liquidity information of the underlying Portfolio Funds by class:

Major Category	Fair Value		Illiquid Investments (1)		Gates (2)		Lock-ups (3)		Redemption Frequency (4)	Redemption Notice Period (4)

Total	$	74,476,546	$	2,818	$	16,987,121	$	11,354,699

(1) Represents private investment funds that cannot be voluntarily redeemed by the Fund at any time. This includes: (i) private investment funds that are liquidating and making distribution payments as their underlying assets are sold, (ii) suspended redemptions/withdrawals, and (iii) side pocket holdings. These types of investments may be realized within 1 to 3 years from March 31, 2015, depending on the specific investment and market conditions. This does not include private investment funds with gates and lockups, which are noted above.

(2) Represents the portion of the Portfolio Funds for which there are investor level gates, which are not otherwise included as illiquid investments.

(3) Represents investments that cannot be redeemed without a fee due to a lock-up provision, which are not otherwise included as illiquid investments or investments with gates. The lock-up period for these investments ranged from 6 to 23 months at March 31, 2015.

(4) Redemption frequency and redemption notice period reflect general redemption terms, and exclude liquidity restrictions noted above.

(a) Relative value strategies seek to profit from the mispricing of financial instruments relative to each other or historical norms. These strategies utilize quantitative and qualitative analyses to identify securities or spreads between securities that deviate from their theoretical fair value and/or historical norms. The application of the Valuation Procedures to investments in this category did not result in any Adjusted Fair Values as of March 31, 2015. The fair values of the investments in this category have been estimated based on the net asset values provided by management of the Portfolio Funds.

(b) Fundamental long/short strategies involve buying or selling predominantly corporate securities believed to be over- or underpriced relative to their potential value. Investment strategies in this category include long and short equity- or credit-based strategies, which emphasize a fundamental valuation framework, and equity active value strategies, where an active role is taken to enhance corporate value. The application of the Valuation Procedures to investments in this category did not result in any Adjusted Fair Values as of March 31, 2015. The fair values of the investments in this category have been estimated based on the net asset values provided by management of the Portfolio Funds.

(c) Event-driven strategies concentrate on companies that are subject to corporate events such as mergers, acquisitions, restructurings, spin-offs, shareholder activism or other special situations that alter a company’s financial structure or operating strategy. The intended goal of these strategies is to profit when the price of a security changes to reflect more accurately the likelihood and potential impact of the occurrence, or nonoccurrence, of the event. The application of the Valuation Procedures to investments in this category did not result in any Adjusted Fair Values as of March 31, 2015. The fair values of the investments in this category have been estimated based on the net asset values provided by management of the Portfolio Funds.

(d) Directional trading seeks to profit in changes from macro-level exposures, such as broad securities markets, interest rates, exchange rates and commodities. Examples include global macro strategies that express macroeconomic views based on analysis of fundamental factors and managed futures strategies, which select futures instruments based typically on systematic technical analysis. The application of the Valuation Procedures to investments in this category did not result in any Adjusted Fair Values as of March 31, 2015. The fair values of the investments in this category have been estimated based on the net asset values provided by management of the Portfolio Funds.

The Fund had no unfunded capital commitments as of March 31, 2015.

4. Investment Advisory Agreement and Other Transactions with Affiliates:

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

The Fund entered into an Investment Advisory Agreement with the Advisor to provide investment advisory services. The Fund pays the Advisor an annual fee accrued monthly and payable quarterly in arrears, in an amount equal to 0.75% of the Fund’s month-end members’ capital.

The Advisor had entered into a separate sub-advisory agreement with BlackRock Financial Management, Inc. (“BFM”), an affiliate of the Advisor. The Advisor paid BFM for services it provided, a monthly fee that is a percentage of the investment advisory fees paid by the Fund to the Advisor. Effective July 1, 2014, the sub-advisory agreement with BFM expired.

The Fund has entered into an expense limitation agreement (“Expense Agreement”) in which the Advisor has agreed to reimburse certain operating and other expenses of the Fund in order to limit certain expenses to 0.50% per annum of the Fund’s average month-end members’ capital (the “Expense Cap”). Expenses covered by the Expense Cap include all of the Fund’s expenses other than those expressly excluded by the Expense Agreement as follows: (i) the investment management fee, (ii) interest expense, if any, (iii) expenses incurred directly or indirectly by the Fund as a result of expenses related to investing in, or incurred by, a Portfolio Fund or other permitted investment, (iv) any trading-related expenses, including, but not limited to, clearing costs and commissions, (v) dividends on short sales, if any, (vi) any extraordinary expenses not incurred in the ordinary course of the Fund’s business (including, without limitation, litigation expenses) and (vii) if applicable, the distribution fees paid to BlackRock Investments, LLC (“BRIL”) or financial intermediaries.

If the Fund has received a waiver or reimbursement from the Advisor within the prior two fiscal years and the Fund’s operating expenses are less than the expense limit for the Fund, the Advisor is entitled to be reimbursed by the Fund up to the lesser of (a) the amount of fees waived or expenses reimbursed during those prior two fiscal years under the agreement and (b) the amount by which the expense limit for the Fund exceeds the operating expenses of the Fund for the current fiscal year, provided that: (1) the Fund has more than $50 million in assets for the fiscal year and (2) the Advisor or an affiliate continues to serve as the Fund’s investment advisor or administrator. In the event the expense limit for the Fund is changed subsequent to a fiscal year in which the Advisor becomes entitled to reimbursement for fees waived or reimbursed, the amount available to reimburse the Advisor shall be calculated by reference to the expense limit for the Fund in effect at the time the Advisor became entitled to receive such reimbursement, rather than the subsequently changed expense limit for the Fund.

On March 31, 2015, the amounts subject to possible future recoupment under the expense limitation agreement were as follows:

	2015	2016	2017
Expiring March 31,	$600,838	$242,757	$172,537

The Fund entered into a Distribution Agreement with BRIL, an affiliate of the Advisor. Pursuant to a Distribution Plan approved by the Fund’s Board, the Fund pays BRIL ongoing distribution fees. The fees are accrued monthly and paid quarterly in arrears at an annual rate equal to 0.75% of the Fund’s month-end members’ capital.

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

5. Purchases and Sales:

For the year ended March 31, 2015, purchases and sales of investments, excluding short-term securities, were $14,900,000 and $23,474,417, respectively.

6. 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 members. 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 periods ended March 31, 2015. 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, 2015, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

Notes to Financial Statements (continued)

U.S. GAAP requires that certain components of members’ capital be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on members’ capital or net asset values per unit. As of March 31, 2015, the following permanent differences attributable to the sale of stock of passive foreign investment companies were reclassified to the following accounts:

Accumulated net investment loss	$	3,335,183
Accumulated net realized loss	$	(3,335,183	)

The tax character of distributions paid was as follows:

	3/31/15		3/31/14
Ordinary income	$	3,158,141	$	5,583,421

As of March 31, 2015, the tax components of accumulated net earnings were as follows:

Undistributed ordinary income	$	3,577,448
Capital loss carryforwards		(857,621	)
Net unrealized losses1		(191,455	)
Qualified late-year losses2		(123,531	)
Total	$	2,404,841

¹  The difference between book-basis and tax-basis net unrealized losses was attributable primarily to the realization for tax purposes of unrealized gains on investments in passive foreign investment companies.

²  The Fund has elected to defer certain qualified late-year losses and recognize such losses in the next taxable year.

As of March 31, 2015, the Fund had capital loss carryforwards, with no expiration dates, available to offset future realized capital gains of $857,621.

As of March 31, 2015, gross unrealized appreciation and depreciation based on cost for federal income tax purposes were as follows:

Tax cost	$	74,668,001
Gross unrealized appreciation		—
Gross unrealized depreciation	$	(191,455	)
Net unrealized depreciation	$	(191,455	)

7. Principal Risks:

The Fund’s investments in Portfolio Funds involve varying degrees of interest rate risk, credit and counterparty risk, and market, industry or geographic concentration risks for the Fund. While BlackRock monitors these risks, the varying degrees of transparency into and potential illiquidity of the securities in the Portfolio Funds may hinder BlackRock’s ability to effectively manage and mitigate these risks.

The Portfolio Funds in which the Fund is invested utilize a wide variety of financial instruments in their trading strategies including over-the-counter options, financial futures contracts, forward contracts and swap agreements, and securities sold but not yet purchased. Several of these financial instruments contain varying degrees of off-balance sheet risk where the maximum potential loss on a particular financial instrument may be in excess of the amounts recorded on each Portfolio Fund’s balance sheet. The Portfolio Funds are required to account for all investments on a fair value basis, and recognize changes in unrealized gains and losses in their statements of operations. In determining the fair values for these financial instruments, the Portfolio Funds will make estimates about future interest rates, default probabilities, volatilities and other pricing factors. These estimates of fair value could differ from actual results.

The Fund’s maximum exposure to market risks of the Portfolio Funds is limited to amounts included in the Fund’s investments in Portfolio Funds recorded as assets on the Statement of Assets, Liabilities and Members’ Capital.

The Fund is designed primarily for long term investors and an investment in the Fund’s Units should be considered to be illiquid. The Fund’s Units are not and will not be listed for trading on a securities exchange. Members may not be able to sell their Units as it is unlikely that a secondary market for the Units will develop or, if a secondary market does develop, members may be able to sell their Units only at substantial discounts from net asset value. Additionally, transfers of Units generally may not be effected without the express written consent of the Board or it’s delegate. The Fund may, but is not obligated to, conduct tender offers to repurchase outstanding Units. If the Fund does conduct tender offers, it may be required to sell its more liquid, higher quality portfolio securities to purchase Units that are tendered, which may increase risks for remaining members and increase Fund expenses.

20 BLACKROCK PREFERRED PARTNERS LLC MARCH 31, 2015

Notes to Financial Statements (continued)

The Portfolio Funds invest in securities and investments with various degrees of liquidity and as such the Fund is subject to certain redemption/ withdrawal provisions, in accordance with the Portfolio Funds’ offering agreements.

Certain of the Fund’s Portfolio Funds have the ability to suspend redemptions/withdrawals, and restrict redemptions/withdrawals through the creation of side pockets. The Fund’s ability to liquidate its investment in Portfolio Funds that had imposed such provisions may be adversely impacted. In such cases, until the Fund is permitted to liquidate its interest in the Portfolio Fund, any interest the Fund retains in such Portfolio Fund remains subject to continued exposure to changes in valuations.

The Fund also invests in closed-end investments that may not permit redemptions/withdrawals or in Portfolio Funds that impose an initial “lockup” period before a redemption/withdrawal can be made. In addition, certain of the Fund’s Portfolio Funds have the ability to impose redemption gates, and in so doing, may reduce the Fund’s requested redemption/withdrawal below the requested amount. The amount of the Fund’s assets subject to lockups and gates is described in Note 3.

8. Capital Transactions:

For the year ended March 31, 2014, Units issued and outstanding increased 1,851,526 as a result of Units sold and 532,221 for reinvestment of distributions. For the year ended March 31, 2015, Units issued and outstanding decreased 375,144 as a result of Units repurchased in tender offers. At March 31, 2015, 969,980 Units were owned by BlackRock Holdco 2, Inc., an affiliate of the Fund.

Units are offered at closings, for purchase as of the first business day of each month or at such other times as determined in the discretion of the Board.

The Fund may choose to conduct quarterly tender offers for up to 15% of its net asset value at the time in the sole discretion of its Board. In a tender offer, the Fund repurchases outstanding Units at the Fund’s net asset value on the valuation date for the tender offer, which would generally be the last business day of March, June, September or December. In any given year, the Advisor may or may not recommend to the Board that the Fund conduct tender offers. Accordingly, there may be years in which no tender offer is made. Therefore, Units will not be redeemable at an investor’s option nor will they be exchangeable for shares of any other fund.

Tender offers were as follows:

Commencement Date1	Valuation Date	Units Offered to Repurchase		Tendered Units
June 28, 2013	September 30, 2013		816,555		20,420
September 27, 2013	December 31, 2013		866,423		407,864
December 26, 2013	March 31, 2014		989,446		330,000
March 27, 2014	June 30, 2014		1,144,353		581,318
June 27, 2014	September 30, 2014		1,169,187		430,411
September 26, 2014	December 31, 2014		1,134,890		423,825
December 29, 2014	March 31, 2015		1,134,890		—	2
March 27, 2015	June 30, 2015		1,127,088		—	2

¹  Date the tender offer period begins.

²  The number of tendered Units will be included in each of the Fund’s final amendments to its Schedule TO related to each tender offer. Each final amendment will be filed with the Securities and Exchange Commission (“SEC”) upon payment of the final proceeds. The proceeds are paid in accordance with the terms and dates described in each Schedule TO filed with the SEC (typically an initial payment of approximately 90% within 45 days and the balance within 90 days from the tender offer’s valuation date).

Tendered Unit amounts are shown as repurchase of Units resulting from tender offers in the Statements of Changes in Members’ Capital.

A 2.00% early repurchase fee payable to the Fund will be charged to any member that tenders its Units to the Fund in connection with a tender offer with a valuation date that is prior to the one-year anniversary of the member’s purchase of the respective Units. The purpose of the 2.00% early repurchase fee is to reimburse the Fund for the costs incurred in liquidating investments in the Fund’s portfolio in order to honor the member’s repurchase request and to discourage short-term investments which are generally disruptive to the Fund’s investment program. This early repurchase fee would apply separately to each purchase of Units made by a member.

The Fund may, in its sole discretion, waive the early repurchase fee under certain circumstances described in the Fund’s prospectus.

9. Subsequent Events:

Management has evaluated the impact of all subsequent events on the Fund 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

To the Board of Directors and Members of BlackRock Preferred Partners LLC:

We have audited the accompanying statement of assets and liabilities and members’ capital of BlackRock Preferred Partners LLC (the “Fund”), including the schedule of investments, as of March 31, 2015, and the related statement of operations and statement of cash flows for the year then ended, the statements of changes in members’ capital for each of the two years in the period then ended and the financial highlights for the periods presented. 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. Our procedures included confirmation of portfolio funds owned as of March 31, 2015, by correspondence with the portfolio funds’ third party investment advisor or administrator. We believe that our audits provides a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of BlackRock Preferred Partners LLC as of March 31, 2015, the results of its operations and cash flows for the year then ended, the changes in its members’ capital for each of the two years in the period then ended, and the financial highlights for the periods presented, in conformity with accounting principles generally accepted in the United States of America.

Automatic Dividend Reinvestment Plan

Unless the registered owner of Units elects to receive cash by contacting the Plan Administrator, all dividends declared for a Member’s Units in the Fund will be automatically reinvested by The Bank of New York Mellon (the “Plan Administrator”), administrator for Members in administering the Fund’s Dividend Reinvestment Plan (the “Plan”), in additional Units of the Fund. Members who elect not to participate in the Plan will receive all dividends and other distributions in cash paid by check mailed directly to the Member of record (or, if the Units are held in street or other nominee name, then to such nominee) by The Bank of New York Mellon, as dividend disbursing agent. You may elect not to participate in the Plan and to receive all dividends in cash by contacting The Bank of New York Mellon, as dividend disbursing agent, at the address set forth below. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notice if received and processed by the Plan Administrator prior to the dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Some brokers may automatically elect to receive cash on your behalf and may re-invest that cash in additional Units of the Fund for you. If you wish for all dividends declared on your Units of the Fund to be automatically reinvested pursuant to the Plan, please contact your broker.

The Plan Administrator will open an account for each Member under the Plan in the same name in which such Member’s Units are registered. Whenever the Fund declares a dividend or other distribution (together, a “Dividend”) payable in cash, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in Units. The Units will be acquired by the Plan Administrator for the participants’ accounts through receipt of additional unissued but authorized Units from the Fund (“Newly Issued Units”).

The Plan Administrator will invest the Dividend amount in Newly Issued Units on behalf of the participants. The number of Newly Issued Units to be credited to each participant’s account will be determined by dividing the dollar amount of the Dividend by the net asset value per Unit as of the last Business Day of the calendar month in which the payment date occurs. Units will be issued to Plan participants in accordance with the Fund’s regular monthly subscription cycle as described herein.

The Plan Agent will maintain all Members’ accounts in the Plan and furnish written confirmation of all transactions in the accounts, including information needed by Members for tax records. Units in the account of each Plan participant will be held by the Plan Agent on behalf of the Plan participant, and each Member proxy will include those Units received pursuant to the Plan. The Plan Administrator will forward all proxy solicitation materials to participants and vote proxies for Units held under the Plan in accordance with the instructions of the participants.

In the case of Members such as banks, brokers or nominees which hold Units for others who are the beneficial owners, the Plan Administrator will administer the Plan on the basis of the number of Units certified from time to time by the record Member’s name and held for the account of beneficial owners who participate in the Plan.

There will be no charges with respect to Units issued directly by the Fund as a result of dividends or capital gains distributions payable either in Units or in cash. The Plan Administrator’s fees for the handling of the reinvestment of dividends and distributions will be paid by the Fund. The automatic reinvestment of Dividends will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends. The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants with regard to purchases in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants.

All correspondence concerning the Plan should be directed to the Plan Administrator at BNY Mellon Alternative Investments, c/o Investor Services, 400 Bellevue Parkway, 2nd Floor (19C-0204), Wilmington, DE 19809; or by calling 1-866-211-4521.

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

The 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 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 registrant 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 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

3

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 the Committee pursuant to the de minimis 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
BlackRock Preferred Partners LLC	$15,147	$14,850

Additionally, SSAE 16 Review (Formerly, SAS No. 70) fees for the current and previous fiscal years of $2,391,000 and $2,555,000, respectively, were billed by D&T to the Investment Adviser.

(h) The 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.

Item 5 –	Audit Committee of Listed Registrants
	(a)	The following individuals are members of the registrant’s separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (15 U.S.C. 78c(a)(58)(A)):
		Michael Castellano Frank J. Fabozzi James T. Flynn W. Carl Kester Karen P. Robards
	(b)	Not Applicable
Item  6 –	Investments

	(b) Not Applicable due to no such divestments during the semi-annual period covered since the previous Form N-CSR filing.
Item 7 –	Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies – The board of directors has delegated the voting of proxies for the Fund’s portfolio securities to the Investment Adviser pursuant to the Investment Adviser’s proxy voting guidelines. Under these guidelines, the Investment Adviser will vote proxies related to Fund securities in the best interests of the Fund and its stockholders. From time to time, a vote may present a conflict between the interests of the Fund’s stockholders, on the one hand, and those of the Investment Adviser, or any affiliated person of the Fund or the Investment Adviser, on the other. In such event, provided that the Investment Adviser’s Equity Investment Policy Oversight Committee, or a sub-committee thereof (the “Oversight Committee”) is aware of the real or potential conflict or material non-routine matter and if the Oversight Committee does not reasonably believe it is able to follow its general voting guidelines (or if the particular proxy matter is not addressed in the guidelines) and vote impartially, the Oversight Committee may retain an independent fiduciary to advise the Oversight Committee on how to vote or to cast votes on behalf of the Investment Adviser’s clients. If the Investment Adviser determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Oversight Committee shall determine how to vote the proxy after consulting with the Investment Adviser’s Portfolio Management Group and/or the Investment Adviser’s Legal and Compliance Department and concluding that the vote cast is in its client’s best interest notwithstanding the conflict. A copy of the Fund’s Proxy Voting Policy and Procedures are attached as Exhibit 99.PROXYPOL. Information on how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge, (i) at www.blackrock.com and (ii) on the SEC’s website at http://www.sec.gov.

(iv) Potential Material Conflicts of Interest

BlackRock has built a professional working environment, firm-wide compliance culture and compliance procedures and systems designed to protect against potential incentives that may favor one account over another. BlackRock has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, BlackRock furnishes investment management and advisory services to numerous clients in addition to the Fund, and BlackRock may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to BlackRock, or in which portfolio managers have a personal interest in the receipt of such fees), which may be the same as or different from those made to the Fund. In addition, BlackRock, Inc., its affiliates and significant shareholders and any officer, director, shareholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, Inc., or any of its affiliates or significant shareholders, or any officer, director, shareholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock, Inc.’s (or its affiliates’ or significant shareholders’) officers, directors or employees are directors or officers, or companies as to which BlackRock, Inc. or any of its affiliates or significant shareholders or the officers, directors and employees of any of them has any substantial economic interest or possesses material non-public information. Certain portfolio managers also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for a fund. It should also be noted that Messrs. Rzeszowski and Sideratos may be managing hedge fund and/or long only accounts, or may be part of a team managing hedge fund and/or long only accounts, subject to incentive fees. Messrs. Rzeszowski and Sideratos may therefore be entitled to receive a portion of any incentive fees earned on such accounts.

As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock, Inc. has adopted policies that are intended to ensure reasonable efficiency in client transactions and provide BlackRock with sufficient

6

flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base, as appropriate.

(a)(3) As of March 31, 2015:

Portfolio Manager Compensation Overview

The discussion below describes the portfolio managers’ compensation as of March 31, 2015.

BlackRock’s financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock.

Base compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

Discretionary Incentive Compensation

Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm’s assets under management or supervision by that portfolio manager, and the individual’s performance and contribution to the overall performance of these portfolios and BlackRock. Among other things, BlackRock’s Chief Investment Officers make a subjective determination with respect to each portfolio manager’s compensation based on the performance of the Funds and other accounts managed by each portfolio manager. Performance of multi-asset class funds is generally measured on a pre-tax basis over various time periods including 1-, 3- and 5- year periods, as applicable. With respect to these portfolio managers, such benchmarks for the Fund and other accounts are:

Portfolio Manager	Applicable Benchmarks
Edward Rzeszowski	HFRI Fund of Funds Composite Index and Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index
Nicholas Sideratos	HFRI Fund of Funds Composite Index

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. For some portfolio managers, discretionary incentive compensation is also distributed in deferred cash awards that notionally track the returns of select BlackRock investment products they manage and that vest ratably over a number of years. The BlackRock, Inc. restricted stock units, upon vesting, will be settled in

7

BlackRock, Inc. common stock. Typically, the cash portion of the discretionary incentive compensation, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of discretionary incentive compensation in BlackRock, Inc. stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability to sustain and improve its performance over future periods. Providing a portion of discretionary incentive compensation in deferred cash awards that notionally track the BlackRock investment products they manage provides direct alignment with investment product results.

Long-Term Incentive Plan Awards — From time to time long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock. The portfolio managers of this Fund have unvested long-term incentive awards.

Deferred Compensation Program — A portion of the compensation paid to eligible United States-based BlackRock employees may be voluntarily deferred at their election for defined periods of time into an account that tracks the performance of certain of the firm’s investment products. Any portfolio manager who is either a managing director or director at BlackRock with compensation above a specified threshold is eligible to participate in the deferred compensation program.

Other Compensation Benefits. In addition to base salary and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (RSP), and the BlackRock Employee Stock Purchase Plan (ESPP). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the Internal Revenue Service limit ($265,000 for 2015). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into a target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the purchase date. All of the eligible portfolio managers are eligible to participate in these plans.
