Past performance is no guarantee of future results. Index performance shown for
illustrative purposes only. You cannot invest directly in an index.

Subprime mortgage woes dominated headlines for much of 2007, but intensified in
the summer and fall, spawning a widespread liquidity and credit crisis with
ramifications across global markets. The Federal Reserve Board (the "Fed") and
other countries' central banks stepped in to inject liquidity into the markets
and bolster investor confidence. The Fed cut the federal funds rate by 0.50% in
September and another 0.25% on the final day of the reporting period, bringing
its target rate to 4.50%. In taking action, the central bankers, who had long
deemed themselves inflation fighters, were seeking to stem the fallout from the
credit crunch and forestall a wider economic unraveling. By period-end, the Fed
had cited the risks between slower economic growth and faster inflation as
equally balanced.

Amid the volatility throughout the past year, equity markets have displayed
surprising resilience. Most recently, the credit turmoil dampened corporate
merger-and-acquisition (M&A) activity, a key source of strength for equity
markets. Still, market fundamentals have held firm, dividend payouts and share
buybacks have continued to grow, and valuations remain attractive. These
tailwinds generally have prevailed over the headwinds created by the slowing
U.S. economy, troubled housing market and, recently, a more difficult corporate
earnings backdrop. International markets fared even better than U.S. equities,
benefiting from robust M&A activity and generally stronger economies.

In fixed income markets, mixed economic signals and the credit woes resulted in
a flight to quality. At the height of the uncertainty, investors shunned bonds
associated with the housing and credit markets in favor of higher-quality
Treasury issues. The yield on 10-year Treasury issues, which touched 5.30% in
June (its highest level in five years), fell to 4.48% by period-end, while
prices correspondingly rose. The tax-exempt bond market has been challenged by a
combination of record-setting supply year-to-date, economic uncertainty and
concerns around the credit worthiness of bond insurers. This has brought
municipal bond prices to relatively attractive levels and, as such, demand
generally has remained firm.

As you navigate market volatility, we encourage you to review your investment
goals with your financial professional and to make portfolio changes, as needed.

Fund Summary                                       BlackRock Large Cap Core Fund

Portfolio Management Commentary

      How did the Fund perform?

o     The Fund generated strong absolute returns for the fiscal year, but
      slightly underperformed its benchmark, the Russell 1000 Index.

      What factors influenced performance?

o     At a very high level, strong performance generated by asset allocation
      decisions was offset by disappointing stock selection results.

o     The Fund's favorable asset allocation decisions, through its investment in
      Master Large Cap Core Portfolio, included overweight positions in energy
      and information technology, and an underweight in financials. The Fund's
      weighting in financials is significantly below that of the benchmark,
      particularly in commercial banks and mortgage companies.

o     Stock selection within the health care sector enhanced performance,
      particularly in biotechnology companies and service providers. Stock
      selection within the industrials and materials sectors also contributed
      positively to returns. The largest individual contributors to performance
      were Southern Copper Corp., Tesoro Corp., EMC Corp., The Goodyear Tire &
      Rubber Co. and Frontier Oil Corp.

o     Stock selection in energy and information technology (IT) offset the
      aforementioned gains stemming from allocation decisions in these sectors.
      Within energy, recent underperformance is attributed largely to the
      refiners, which came under pressure in the third quarter of 2007 as
      margins were expected to compress. However, we believed that refiners were
      oversold and added to some of our positions on price weakness. Within
      technology, our lack of ownership of a few outperforming companies and
      stock-specific disappointments in the semiconductor, software and IT
      services areas hurt performance. The largest individual detractors were
      Apple, Lexmark International, Inc., BEA Systems, Inc., RadioShack Corp.
      and Electronic Data Systems Corp.

o     The Fund's overweight position and stock selection in consumer
      discretionary proved negative for the period. Given ongoing concerns about
      consumer spending, we shifted the cyclical bias of the Fund away from the
      domestic consumer and toward more global, industrial-based companies.

      Describe recent portfolio activity.

o     During the period, we increased the Fund's exposure to information
      technology and telecommunication services. Among our largest purchases
      were American International Group, Inc., ConocoPhillips, UnitedHealth
      Group, Inc., Valero Energy Corp. and Applied Materials, Inc.

o     We reduced exposure to the consumer discretionary, energy, financials,
      industrials, consumer staples and materials sectors. Our largest sales
      included JPMorgan Chase & Co., Biogen Idec, Inc., Morgan Stanley, CSX and
      Goldman Sachs Group, Inc.

      Describe the Fund's positioning at period-end.

o     Relative to its benchmark, the Fund ended the fiscal year overweight in
      information technology, health care, consumer discretionary and energy,
      and underweight in financials, consumer staples, utilities and
      telecommunication services.

o     In our view, stocks are now more susceptible to economic and earnings
      disappointments than they were during the initial stages of the Federal
      Reserve Board's easing cycle. However, we believe more monetary relief
      should be in the pipeline, as economic conditions warrant further
      stimulus. Importantly, we do not believe inflation stands in the way of
      more rate cuts. As the economic data worsens, reflation should strengthen
      as the dominant market force, setting the stage for higher valuations.

Portfolio Management Commentary

      How did the Fund perform?

o     The Fund generated strong absolute returns for the fiscal year, but
      modestly underperformed its benchmark, the Russell 1000 Growth Index.

      What factors influenced performance?

o     At a very high level, the Fund's favorable stock selection, through its
      investment in Master Large Cap Growth Portfolio, in health care and
      industrials provided the most significant positive contribution to
      performance. Disappointing stock selection in the information technology
      and consumer discretionary sectors accounted for the majority of the
      underperformance.

o     Stock selection and an underweighting of the consumer staples sector
      benefited performance. Stock selection also was strong in health care,
      where we took profits in service companies. We view these companies as
      trading vehicles given the countervailing influences of positive
      fundamentals and negative political pressures. Stock selection within the
      industrials sector, particularly among machinery companies, also enhanced
      Fund returns. The largest individual contributors to performance were
      Southern Copper Corp., Cisco Systems, Inc., Juniper Networks, Inc.,
      Raytheon Co. and Biogen Idec, Inc.

o     Stock selection in the energy sector (particularly in oil equipment and
      services companies) and in the consumer discretionary sector (notably in
      specialty and multi-line retailers) detracted from results. The
      performance-enhancing overweight in information technology (IT) was offset
      by poor stock selection within the sector as semiconductors, IT services,
      software and computers & peripherals did not perform as anticipated. The
      largest individual detractors included RadioShack Corp., Compuware Corp.,
      CH Richard Ellis Group, Inc., Convergys Corp. and Electronic Data Systems
      Corp.

o     Within information technology, we increased our weightings in companies
      with global exposure, where we believe there is significant upside
      potential. Within industrials and materials, we own a number of large,
      globally exposed companies benefiting from the commodity boom and general
      demand strength from both developing and emerging markets outside the
      United States.

      Describe recent portfolio activity.

o     Over the course of the year, we increased the Fund's exposure to health
      care and information technology. Among our largest purchases were CA Inc.,
      UnitedHealth Group, Inc., Dell, Inc., Valero Energy Corp. and RadioShack
      Corp.

o     We reduced exposure to the consumer discretionary, industrials, financials
      and materials sectors. Our largest sales included Biogen Idec, Inc.,
      Emdeon Corp., The Goldman Sachs Group, Inc., AMR Corp. and Continental
      Airlines, Inc.

      Describe the Fund's positioning at period-end.

o     Relative to its benchmark, the Fund ended the fiscal year overweight in
      information technology, consumer discretionary and materials, and
      underweight in consumer staples, financials and utilities.

o     In our view, stocks are now more susceptible to economic and earnings
      disappointments than they were during the initial stages of the Federal
      Reserve Board's easing cycle. However, we believe more monetary relief
      should be in the pipeline, as economic conditions warrant further

Fund Summary                                      BlackRock Large Cap Value Fund

Portfolio Management Commentary

      How did the Fund perform?

o     The Fund delivered strong absolute performance for the fiscal year,
      outperforming its benchmark, the Russell 1000 Value Index.

      What factors influenced performance?

o     The Fund's outperformance is attributed to both asset allocation and stock
      selection decisions. The Fund benefited, through its investment in Master
      Large Cap Value Portfolio, from its underweight position in financials and
      overweight in industrials, and from good stock selection in financials,
      health care and industrials.

o     Within financials, the Fund is significantly underweight the benchmark,
      particularly in commercial banks, which have lagged recently. Stock
      selection among capital markets players and diversified financial services
      firms contributed positively.

o     Stock selection and an overweight position in the industrials sector
      enhanced performance, thanks primarily to stock selection in the aerospace
      & defense and machinery areas. Within health care, service providers and
      biotechnology contributed positively to performance. The largest
      individual contributors included Tesoro Corp., EMC Corp., SPX Corp.,
      Biogen Idec, Inc. and Frontier Oil Corp.

o     Partially offsetting these positives was the combination of stock
      selection and an underweighting of the telecommunication services and
      utilities sectors. Stock selection was negative in consumer staples and
      information technology, and gains achieved from overweighting the energy
      sector were offset by poor stock performance. The biggest individual
      detractors included King Pharmaceuticals, Inc., ConocoPhillips, Lexmark
      International, Inc., BEA Systems, Inc. and Occidental Petroleum Corp.

o     Stock selection and an overweight position in consumer discretionary
      hindered the Fund's relative results. Given ongoing concerns about
      consumer spending, we shifted the cyclical bias of the portfolio away from
      the domestic consumer and toward more global, industrial-based companies.

      Describe recent portfolio activity.

o     Over the course of the year, we increased the Fund's exposure to health
      care, utilities and telecommunication services. Among our largest
      purchases were ConocoPhillips, American International Group, Inc., General
      Electric Co., Valero Energy Corp. and Deere & Co.

o     We reduced exposure to the consumer discretionary, financials, energy and
      consumer staples sectors. Our largest sales included Citigroup, Inc.,
      Biogen Idec, Inc., Prudential Financials, Inc., Lehman Brothers Holdings,
      Inc. and Merck & Co., Inc.

      Describe the Fund's positioning at period-end.

o     Relative to its benchmark, the Fund ended the fiscal year overweight in
      information technology, health care, energy, industrials and materials,
      and underweight in financials, utilities, telecommunication services,
      consumer staples and consumer discretionary.

o     In our view, stocks are now more susceptible to economic and earnings
      disappointments than they were during the initial stages of the Federal
      Reserve Board's easing cycle. However, we believe more monetary relief
      should be in the pipeline, as economic conditions warrant further
      stimulus. Importantly, we do not believe inflation stands in the way of
      more rate cuts. As the economic data worsens, reflation should strengthen
      as the dominant market force, setting the stage for higher valuations.

o     Institutional Shares are not subject to any sales charge. Institutional
      Shares bear no ongoing distribution or service fees and are available only
      to eligible investors.

o     Service Shares are not subject to any sales charge. Service Shares are
      subject to a service fee of 0.25% per year (but no distribution fee) and
      are available only to eligible investors. For BlackRock Large Cap Growth
      Fund and BlackRock Large Cap Value Fund, prior to October 2, 2006, Service
      Share performance results are those of Institutional Shares (which have no
      distribution or service fees) restated to reflect the Service Share fees.
      For BlackRock Large Cap Core Fund, prior to September 24, 2007, Service
      Share performance results are those of Institutional Shares (which have no
      distribution or service fees) restated to reflect the Service Share fees.

o     Investor A Shares incur a maximum initial sales charge (front-end load) of
      5.25% and a service fee of 0.25% per year (but no distribution fee).

o     Investor B Shares are subject to a maximum contingent deferred sales
      charge of 4.50% declining to 0% after six years. In addition, Investor B
      Shares are subject to a distribution fee of 0.75% per year and a service
      fee of 0.25% per year. These shares automatically convert to Investor A
      Shares after approximately eight years. (There is no initial sales charge
      for automatic share conversions.) All returns for periods greater than
      eight years reflect this conversion.

o     Investor C Shares are subject to a distribution fee of 0.75% per year and
      a service fee of 0.25% per year. In addition, Investor C Shares are
      subject to a 1% contingent deferred sales charge if redeemed within one
      year of purchase.

o     Class R Shares do not incur a maximum initial sales charge (front-end
      load) or deferred sales charge. These shares are subject to a distribution
      fee of 0.25% per year and a service fee of 0.25% per year. Class R Shares
      are available only to certain retirement plans. Prior to inception, Class
      R Share performance results are those of Institutional Shares (which have
      no distribution or service fees) restated to reflect Class R Share fees.

      Performance information reflects past performance and does not guarantee
      future results. Current performance may be lower or higher than the
      performance data quoted. Refer to www.blackrock.com/funds to obtain
      performance data current to the most recent month-end. Performance results
      do not reflect the deduction of taxes that a shareholder would pay on fund
      distributions or the redemption of fund shares. Performance data does not
      reflect this potential fee. Figures shown in each of the performance
      tables on page 11 assume reinvestment of all dividends and capital gain
      distributions, if any, at net asset value on the ex-dividend date.
      Investment return and principal value of shares will fluctuate so that
      shares, when redeemed, may be worth more or less than their original cost.
      Dividends paid to each class of shares will vary because of the different
      levels of service, distribution and transfer agency fees applicable to
      each class, which are deducted from the income available to be paid to
      shareholders.


Disclosure of Expenses                    BlackRock Large Cap Series Funds, Inc.

Shareholders of these Funds may incur the following charges: (a) expenses
related to transactions, including sales charges, redemption fees and exchange
fees; and (b) operating expenses including advisory fees, distribution fees
including 12b-1 fees, and other Fund expenses. The expense examples on page 11
(which are based on a hypothetical investment of $1,000 invested on May 1, 2007
and held through October 31, 2007) are intended to assist shareholders both in
calculating expenses based on an investment in each Fund and in comparing these
expenses with similar costs of investing in other mutual funds.

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

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

The expenses shown in the tables are intended to highlight shareholders' ongoing
costs only and do not reflect any transactional expenses, such as sales charges,
redemption fees or exchange fees. Therefore, the hypothetical tables 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.

28        BLACKROCK LARGE CAP SERIES FUNDS, INC.        OCTOBER 31, 2007


Notes to Financial Statements             BlackRock Large Cap Series Funds, Inc.

1. Significant Accounting Policies:

BlackRock Large Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock
Large Cap Value Fund (the "Funds" or individually as the "Fund"), constituting
BlackRock Large Cap Series Funds, Inc., are registered under the Investment
Company Act of 1940, as amended, as diversified, open-end investment companies.
Each Fund seeks to achieve its investment objective by investing all, or a
portion of, its assets in Master Large Cap Core Portfolio, Master Large Cap
Growth Portfolio and Master Large Cap Value Portfolio (the "Portfolios" or
individually as the "Portfolio"), respectively, of Master Large Cap Series LLC
(the "Master LLC"), which have the same investment objective and strategies as
the corresponding Funds. The value of the Funds' investment in the Portfolios
reflects the Funds' proportionate interest in the net assets of the Portfolios.
The performance of the Funds is directly affected by the performance of the
Portfolios. The financial statements of the Portfolios, including the Schedules
of Investments, are included elsewhere in this report and should be read in
conjunction with the Funds' financial statements. The Funds' financial
statements are prepared in conformity with U.S. generally accepted accounting
principles, which may require the use of management accruals and estimates.
Actual results may differ from these estimates. The percentages of Master Large
Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value
Portfolio owned by BlackRock Large Cap Core Fund, BlackRock Large Cap Growth
Fund and BlackRock Large Cap Value Fund were 97.1%, 96.4% and 98.5%,
respectively. The Funds offer multiple classes of shares. Institutional and
Service Shares are sold only to certain eligible investors. Investor A Shares
are sold with a front-end sales charge. Shares of Investor B and Investor C may
be subject to a contingent deferred sales charge. Class R Shares are sold only
to certain retirement plans. All classes of shares have identical voting,
dividend, liquidation and other rights and the same terms and conditions, except
that Service, Investor A, Investor B, Investor C and Class R Shares bear certain
expenses related to the shareholder servicing of such shares, and Investor B,
Investor C and Class R Shares also bear certain expenses related to the
distribution of such shares. Each class has exclusive voting rights with respect
to matters relating to its shareholder servicing and distribution expenditures
(except that Investor B shareholders may vote on certain changes to the Investor
A distribution plan). Income, expenses (other than expenses attributable to a
specific class) and realized and unrealized gains and losses are allocated daily
to each class based on its relative net assets. The following is a summary of
significant accounting policies followed by the Funds.

(a) Valuation of investments -- Each Fund records its investment at fair value.
Valuation of securities held by the Portfolios is discussed in Note 1(a) of the
Portfolios' Notes to Financial Statements, which are included elsewhere in this
report.

(b) Investment income and expenses -- Each Fund records daily its proportionate
share of the Portfolio's income, expenses and realized and unrealized gains and
losses. In addition, each Fund accrues its own expenses.

(c) Income taxes -- It is each Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to shareholders. Therefore,
no federal income tax provision is required. Under the applicable foreign tax
law, withholding taxes may be imposed on interest, dividends and capital gains
at various rates.

(d) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(e) Dividends and distributions -- Dividends and distributions paid by each Fund
are recorded on the ex-dividend dates.

(f) Investment transactions -- Investment transactions in each Portfolio are
accounted for on a trade date basis.

(g) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity, including mutual funds, before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
the last net asset value calculation in the first required financial statement
reporting period for fiscal years beginning after December 15, 2006. The impact
on each Fund's financial statements, if any, is currently being assessed.

In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS 157
and its impact on each Fund's financial statements, if any, has not been
determined.

In addition, in February 2007, Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and

Notes to Financial Statements (continued)
                                          BlackRock Large Cap Series Funds, Inc.

disclosure requirements designed to facilitate comparisons between entities that
choose different measurement attributes for similar types of assets and
liabilities. At this time, management is evaluating the implications of FAS 159
and its impact on each Fund's financial statements, if any, has not been
determined.

(h) Reclassifications -- BlackRock Large Cap Core Fund

U.S. generally accepted accounting principles require that certain components of
net assets be adjusted to reflect permanent differences between financial and
tax reporting. Accordingly, during the current year, $12,086,681 has been
reclassified between undistributed net realized capital gains and accumulated
net investment loss as a result of permanent differences attributable to net
operating losses and classification of partnership income. This reclassification
has no effect on net assets or net asset values per share.

BlackRock Large Cap Growth Fund

U.S. generally accepted accounting principles require that certain components of
net assets be adjusted to reflect permanent differences between financial and
tax reporting. Accordingly, during the current year, $6,483,394 has been
reclassified between paid-in capital in excess of par and accumulated net
investment loss as a result of a permanent difference attributable to a net
operating loss. This reclassification has no effect on net assets or net asset
values per share.

2. Investment Advisory Agreement and Transactions with Affiliates:

Each Fund has entered into an Administration Agreement with BlackRock Advisors,
LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc.
Each Fund pays a monthly fee at an annual rate of .25% of the Fund's average
daily net assets for the performance of administrative services (other than
investment advice and related portfolio activities) necessary for the operation
of the Fund.

With respect to the BlackRock Large Cap Core Fund, effective September 24, 2007,
the Manager has contractually agreed to waive the Fund's administration fee in
the amount of the Fund's share of the administration fee paid by the Fund. For
the period September 24, 2007 to October 31, 2007, the Manager earned fees of
$1,487,784, of which $329,053 were waived. For the period September 24, 2007 to
October 31, 2007, the Manager contractually agreed to waive and/or reimburse
fees and/or expenses in order to limit expenses (excluding interest expense and
certain other fund expenses) as a percentage of average daily net assets
allocated to certain classes of the Fund as follows: 1.11% (for Investor A
Shares), and 1.91% (for Investor B Shares). The Manager has agreed not to reduce
or discontinue this contractual waiver or reimbursement until October 31, 2008,
unless approved by the Board of Directors of the Fund, including a majority of
the non-interested Directors.

Each Fund has also entered into separate Distribution Agreements and
Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock
Distributors, Inc. and its affiliates ("BDI") (collectively, the "Distributor").
FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc., and BDI is an
affiliate of BlackRock, Inc. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The
PNC Financial Services Group, Inc. ("PNC") are the principal owners of
BlackRock, Inc.

Pursuant to the Distribution Plans adopted by the Funds in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Funds pay each Distributor
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 shares as
follows:

- --------------------------------------------------------------------------------
                                                        Service     Distribution
                                                          Fee           Fee
- --------------------------------------------------------------------------------
Service ..............................................    .25%           --

Investor B ...........................................    .25%          .75%
Investor C ...........................................    .25%          .75%
Class R ..............................................    .25%          .25%
- --------------------------------------------------------------------------------

Pursuant to sub-agreements with each Distributor, broker-dealers, including
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned
subsidiary of Merrill Lynch provide shareholder servicing and distribution
services to the Funds. The ongoing service fee compensates the Distributor and
the broker-dealer (including MLPF&S) for providing shareholder servicing to
Service, Investor A, Investor B, Investor C and Class R shareholders. The
ongoing distribution fee compensates the Distributor and the broker-dealers for
providing shareholder servicing and distribution-related services to Investor B,
Investor C and Class R shareholders.

For the year ended October 31, 2007, FAMD and BDI earned underwriting discounts
and direct commissions and MLPF&S and BDI earned dealer concessions on sales of
the Funds' Investor A Shares as follows:

- --------------------------------------------------------------------------------
                                                                      Investor A

BlackRock Large Cap Growth Fund ..................................    $  350,936

- --------------------------------------------------------------------------------

For the year ended October 31, 2007, affiliates received contingent deferred
sales charges relating to transactions in Investor B and Investor C Shares as
follows:

- --------------------------------------------------------------------------------

Report of Independent Registered Public Accounting Firm BlackRock Large Cap
Series Funds, Inc.

To the Shareholders and Board of Directors of
BlackRock Large Cap Series Funds, Inc.:

We have audited the accompanying statements of assets and liabilities of
BlackRock Large Cap Series Funds, Inc. (the "Fund"), comprising BlackRock Large
Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock Large Cap Value
Fund, as of October 31, 2007, and the related statements 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
BlackRock Large Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock
Large Cap Value Fund of BlackRock Large Cap Series Funds, Inc. as of October 31,
2007, the results of their operations for the year then ended, the changes in
their net assets for each of the two years in the period then ended, and their
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.

Notes to Financial Statements                        Master Large Cap Series LLC

1. Significant Accounting Policies:

Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master
Large Cap Value Portfolio (the "Portfolios" or individually the "Portfolio")
constitute the Master Large Cap Series LLC (the "Master LLC"). The Master LLC is
registered under the Investment Company Act of 1940, as amended, and is
organized as a Delaware limited liability company. Prior to June 15, 2007, the
Master LLC was organized as a Delaware statutory trust (the "Trust"). The
Limited Liability Company Agreement (the "LLC Agreement") permits the Directors
(and prior to June 15, 2007, the Declaration of Trust permitted the Trustees) to
issue nontransferable interests in the Master LLC/Trust, subject to certain
limitations. Throughout this report the Trust and the Master LLC are referred to
as the Master LLC and the Board of Directors of the Master LLC and the Board of
Trustees of the Trust are referred to as the Board of Directors. The Portfolios'
financial statements are prepared in conformity with U.S. generally accepted
accounting principles, which may require the use of management accruals and
estimates. Actual results may differ from these estimates. The following is a
summary of significant accounting policies followed by the Portfolios.

(a) Valuation of investments -- Equity securities held by each Portfolio that
are traded on stock exchanges or the NASDAQ Global Market are valued at the last
sale price or official close price on the exchange, as of the close of business
on the day the securities are being valued or, lacking any sales, at the last
available bid price for long positions, and at the last available asked price
for short positions. In cases where equity securities are traded on more than
one exchange, the securities are valued on the exchange designated as the
primary market by or under the authority of the Board of Directors of the Master
LLC. Long positions traded in the over-the-counter ("OTC") markets, NASDAQ
Capital Market or Bulletin Board are valued at the last available bid price or
yield equivalent obtained from one or more dealers or pricing services approved
by the Board of Directors of the Master LLC. Short positions traded in the OTC
markets are valued at the last available asked price. Portfolio securities that
are traded both in the OTC markets and on a stock exchange are valued according
to the broadest and most representative market.

Effective September 4, 2007, exchange-traded options are valued at the mean
price between the last bid and ask prices at the close of the options market in
which the options trade and previously were valued at the last sales price as of
the close of options trading on applicable exchanges. Options traded in the OTC
market are valued at the last asked price (options written) or the last bid
price (options purchased). Swap agreements are valued based upon quoted fair
valuations received daily by the Portfolios from a pricing service or
counterparty. Financial futures contracts and options thereon, which are traded
on exchanges, are valued at their last sale price as of the close of such
exchanges. Valuation of short-term investment vehicles is generally based on the
net asset value of the underlying investment vehicle or amortized cost.

Repurchase agreements are valued at cost plus accrued interest. Each Portfolio
employs pricing services to provide certain securities prices for the Portfolio.
Securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Board of Directors of the Master LLC, including valuations furnished by the
pricing services retained by each Portfolio, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Master LLC under the general supervision of the Master
LLC's Board of Directors. Such valuations and procedures are reviewed
periodically by the Board of Directors of the Master LLC.

Generally, trading in foreign securities, as well as U.S. government securities,
money market instruments, and certain fixed income securities, is substantially
completed each day at various times prior to the close of business on the New
York Stock Exchange ("NYSE"). The values of such securities used in computing
the net assets of each Portfolio are determined as of such times. Foreign
currency exchange rates will generally be determined as of the close of business
on the NYSE. Occasionally, events affecting the values of such securities and
such exchange rates may occur between the times at which they are determined and
the close of business on the NYSE that may not be reflected in the computation
of each Portfolio's net assets. If events (for example, a company announcement,
market volatility or a natural disaster) occur during such periods that are
expected to materially affect the value of such securities, those securities
will be valued at their fair value as determined in good faith by the Master
LLC's Board of Directors or by BlackRock Advisors, LLC (the "Manager"), an
indirect, wholly owned subsidiary of BlackRock, Inc., using a pricing service
and/or procedures approved by the Master LLC's Board of Directors.

(b) Derivative financial instruments -- Each Portfolio may engage in various
portfolio investment strategies both to increase the return of the Portfolio and
to hedge, or protect, its exposure to interest rate movements and movements in
the securities markets. Losses may arise due to changes in the value of the
contract or if the counterparty does not perform under the contract. The
counterparty for certain instruments may pledge cash or securities as
collateral.

o     Financial futures contracts -- Each Portfolio may purchase or sell
      financial futures contracts and options on such financial futures
      contracts. Financial futures contracts are contracts for delayed delivery
      of securities at a specific date and at a specific price or yield. Upon
      entering into a contract, the Portfolio deposits, and maintains as
      collateral, such initial margin as required by the exchange on which the
      transaction is effected. Pursuant to the contract, the Portfolio agrees to
      receive from or pay to the broker an amount of cash equal to the daily
      fluctuation in value of the contract. Such receipts or payments are known
      as variation margin and are recorded by the Portfolio as unrealized gains
      or losses. When the contract is closed, the Portfolio records a realized
      gain or loss


        BLACKROCK LARGE CAP SERIES FUNDS, INC.        OCTOBER 31, 2007        55


Notes to Financial Statements (continued)            Master Large Cap Series LLC

      equal to the difference between the value of the contract at the time it
      was opened and the value at the time it was closed.

o     Options -- Each Portfolio may purchase and write call and put options.
      When the Portfolio writes an option, an amount equal to the premium
      received by the Portfolio is reflected as an asset and an equivalent
      liability. The amount of the liability is subsequently marked-to-market to
      reflect the current market value of the option written. When a security is
      purchased or sold through an exercise of an option, the related premium
      paid (or received) is added to (or deducted from) the basis of the
      security acquired or deducted from (or added to) the proceeds of the
      security sold. When an option expires (or the Portfolio enters into a
      closing transaction), the Portfolio realizes a gain or loss on the option
      to the extent of the premiums received or paid (or a gain or loss to the
      extent that the cost of the closing transaction exceeds the premium paid
      or received).

      Written and purchased options are non-income producing investments.

(c) Income taxes -- Master Large Cap Core Portfolio and Master Large Cap Value
Portfolio are classified as partnerships for federal income tax purposes. Master
Large Cap Growth Portfolio is considered as a "pass-through" entity for federal
income tax purposes. As such, each investor in the Portfolio is treated as owner
of its proportionate share of the net assets, income, expenses and realized and
unrealized gains and losses of the Portfolio. Therefore, no federal income tax
provision is required. It is intended that the Portfolio's assets will be
managed so an investor in the Portfolio can satisfy the requirements of
Subchapter M of the Internal Revenue Code.

(d) Security transactions and investment income -- Security transactions are
accounted for on the date the securities are purchased or sold (the trade
dates). Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Dividends from foreign securities where the ex-dividend date may have passed are
subsequently recorded when the Portfolio has determined the ex-dividend date.
Interest income is recognized on the accrual basis.

(e) Securities lending -- Each Portfolio may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
market value of the loaned securities is determined at the close of business of
the Portfolio and any additional required collateral is delivered to the
Portfolio on the next business day. Where the Portfolio receives securities as
collateral for the loaned securities, it receives a fee from the borrower. The
Portfolio typically receives the income on the loaned securities, but does not
receive the income on the collateral. Where the Portfolio receives cash
collateral, it may invest such collateral and retain the amount earned on such
investment, net of any amount rebated to the borrower. Loans of securities are
terminable at any time and the borrower, after notice, is required to return
borrowed securities within five business days. The Portfolio may pay reasonable
finders, lending agent, administrative and custodial fees in connection with its
loans. In the event that the borrower defaults on its obligation to return
borrowed securities because of insolvency or for any other reason, the Portfolio
could experience delays and costs in gaining access to the collateral. The
Portfolio also could suffer a loss where the value of the collateral falls below
the market value of the borrowed securities, in the event of borrower default or
in the event of losses on investments made with cash collateral.

(f) Bank overdraft -- Master Large Cap Core Portfolio and Master Large Cap Value
Portfolio each recorded a bank overdraft, which resulted from management
estimates of available cash.

(g) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity, including mutual funds, before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
the last net asset value calculation in the first required financial statement
reporting period for fiscal years beginning after December 15, 2006. The impact
on the Portfolios' financial statements, if any, is currently being assessed.

In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS 157
and its impact on the Portfolios' financial statements, if any, has not been
determined.

In addition, in February 2007, Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is evaluating
the implications of FAS 159 and its impact on the Portfolios' financial
statements, if any, has not been determined.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Master LLC, on behalf of each Portfolio, has entered into an Investment

and The PNC Financial Services Group, Inc. are the principal owners of
BlackRock, Inc.

The Manager is responsible for the management of each Portfolio's investments
and provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Portfolios. Master Large Cap Core
Portfolio pays a monthly fee at an annual rate of .50% of the average daily net
assets not exceeding $1 billion, .45% of average daily net assets in excess of
$1 billion but not exceeding $5 billion and .40% of average daily net assets in
excess of $5 billion; Master Large Cap Growth Portfolio pays a monthly fee at an
annual rate of .50% of the average daily net assets not exceeding $5 billion and
..45% of average daily net assets in excess of $5 billion; and Master Large Cap
Value Portfolio pays a monthly fee at an annual rate of .50% of the average
daily net assets not exceeding $3 billion and .45% of average daily net assets

In addition, the Manager has entered into a sub-advisory agreement with
BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under
which the Manager pays the sub-adviser for services it provides a monthly fee at
an annual rate equal to a percentage of the management fee paid by the
Portfolios to the Manager.

The Portfolios have received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill
Lynch, or its affiliates. As of October 31, 2007, Master Large Cap Core
Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value
Portfolio lent securities with values of $176,250,285, $29,537,387 and
$80,567,856, respectively, to MLPF&S or its affiliates. Pursuant to that order,
the Portfolios have retained BIM as the securities lending agent for a fee based
on a share of the returns on investment of cash collateral. BIM may, on behalf
of the Portfolios, invest cash collateral received by the Portfolios for such
loans, among other things, in a private investment company managed by the
Manager or in registered money market funds advised by the Manager or its
affiliates. For the year ended October 31, 2007, BIM received $464,185, $94,115
and $286,229 in securities lending agent fees for Master Large Cap Core
Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value
Portfolio, respectively.

In addition, MLPF&S received commissions on the execution of portfolio security
transactions for the year ended October 31, 2007. The commissions were as

4. Short-Term Borrowings:

Each Portfolio, along with certain other funds managed by the Manager and its
affiliates, is party to a $500,000,000 credit agreement with a group of lenders,
which expires November 2007 and was subsequently renewed. Each Portfolio may
borrow under the credit agreement to fund shareholder redemptions and for other
lawful purposes other than for leverage. Each Portfolio may borrow up to the
maximum amount allowable under the Portfolio's current prospectus and statement
of additional information, subject to various other legal, regulatory or
contractual limits. The Portfolios pay a commitment fee of .06% per annum based
on the Portfolio's pro rata share of the unused portion of the credit agreement.
Amounts borrowed under the credit agreement bear interest at a rate equal to, at
each fund's election, the federal funds rate plus .35% or a base rate as defined
in the credit agreement. None of the Portfolios borrowed under the credit
agreement during the year ended October 31, 2007.

5. Acquisitions:

reorganization. As a result of the reorganization, which included $286,539,853
of net unrealized appreciation, the Master Large Cap Core Portfolio received an
in-kind contribution of portfolio securities.


        BLACKROCK LARGE CAP SERIES FUNDS, INC.        OCTOBER 31, 2007        57


Report of Independent Registered Public Accounting Firm
                                                     Master Large Cap Series LLC

To the Investors and Board of Directors of
Master Large Cap Series LLC:

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments of Master Large Cap Series LLC (formerly Master
Large Cap Series Trust) (the "Master LLC"), comprising Master Large Cap Core
Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value
Portfolio, as of October 31, 2007, the related statements 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 October 31, 2007, 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
Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap
Value Portfolio of Master Large Cap Series LLC, as of October 31, 2007, the
results of their operations for the year then ended, the changes in their net
assets for each of the two years in the period then ended, and their 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.

            financial experts serving on its audit committee and (ii) each audit

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

                  The registrant's audit committee (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 registrant's affiliated 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"). However, such services will only be deemed
            pre-approved provided that any individual project does not exceed
            $5,000 attributable to the registrant or $50,000 for all of the
            registrants the Committee oversees. 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 subject to general
            pre-approval at the next regularly scheduled in-person board
            meeting.

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

            (h) The registrant's audit committee has considered and determined
            that the provision of non-audit services that were rendered to the
            registrant's investment adviser (not including any non-affiliated
            sub-adviser whose role is primarily portfolio management and is
            subcontracted with or overseen by the registrant's investment
            adviser), and any entity controlling, controlled by, or under common
            control with the investment adviser that provides ongoing services
            to the registrant 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.

            officers or persons performing similar functions have concluded that
