The Markets in Review

Dear Shareholder,

Investment performance in the 12 months ended September 30, 2019 was a tale of two markets. The first half of the reporting period was characterized by restrictive monetary policy, deteriorating economic growth, equity market volatility, and rising fear of an imminent recession. During the second half of the reporting period, stocks and bonds rebounded sharply, as influential central banks shifted toward accommodative monetary policy, which led to broad-based optimism that a near-term recession could be averted.

After the dust settled, equity and bond markets posted mixed returns while weathering significant volatility. Less volatile U.S. large cap equities and U.S. bonds advanced, while equities at the high end of the risk spectrum — emerging markets, international developed, and U.S. small cap — posted modest negative returns.

Fixed-income securities delivered strong returns with relatively low volatility, as interest rates declined (and bond prices rose). U.S. Treasuries, particularly long-term Treasuries, proved to be an effective ballast for diversified investors. Investment grade and high yield corporate bonds also posted positive returns, as the credit fundamentals in corporate markets remained relatively solid.

In the U.S. equity market, volatility spiked in late 2018, as a wide range of risks were brought to bear on markets, ranging from rising interest rates and slowing global growth to heightened trade tensions and political turmoil. Volatility also rose in emerging markets, as the appreciating U.S. dollar and higher interest rates in the U.S. disrupted economic growth abroad. An economic slowdown in Europe and ongoing uncertainty about Brexit led to negative performance for European equities.

As equity performance faltered and global economic growth slowed, the U.S. Federal Reserve (the “Fed”) shifted to a more patient perspective on the economy in January 2019. The Fed left interest rates unchanged for six months, then reduced interest rates twice thereafter. Following in the Fed’s footsteps, the European Central Bank announced aggressive economic stimulus measures, including lower interest rates and the return of its bond purchasing program. The Bank of Japan signaled a continuation of accommodative monetary policy, while China committed to looser credit conditions and an increase in fiscal spending.

The outpouring of global economic stimulus led to a sharp rally in risk assets throughout the world despite the headwind of rising geopolitical and trade tensions. Hopes continued to remain high as the current economic expansion became the longest in U.S. history. Looking ahead, markets are pricing in additional rate cuts by the Fed over the next year, as investors anticipate a steady shift toward more stimulative monetary policy.

We continue to expect a slowing expansion with additional room to run. Despite a sharp slowdown in trade and manufacturing across the globe, U.S. consumers continued to spend at a relatively healthy pace, benefitting from the lowest unemployment rate in 50 years and rising wages. However, escalating trade tensions and the resulting disruptions in global supply chains are becoming increasingly unpredictable, as are geopolitical tensions in the Middle East.

We believe U.S. equities remain relatively attractive, but we are shifting to a more cautious stance within emerging markets and Asiaex-Japan equities. For bonds, U.S. Treasuries are likely to continue to help buffer against volatility in risk assets, while income from other types of bonds can continue to offer steady returns.

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

Sincerely,

Fund Summary as of September 30, 2019		BlackRock Advantage Large Cap Core Fund

Investment Objective

BlackRock Advantage Large Cap Core Fund’s (the “Fund”)investment objective is to seek long-term capital growth. In other words, the Fund tries to choose investments that will increase in value.

Portfolio Management Commentary

How did the Fund perform?

For the12-month period ended September 30, 2019, the Fund, through its investment in Master Advantage Large Cap Core Portfolio (the “Master Portfolio”), underperformed its benchmark, the Russell 1000^® Index.

What factors influenced performance?

Relative performance was challenged toward the end of 2018 and in the third quarter of 2019, causing the Fund to underperform its benchmark over the12-month period. The underperformance occurred in an equity market characterized by increasing volatility and a series of sharp inflection points. Investor behavior was largely driven by broad macroeconomic and geopolitical events such as shifts in trade rhetoric, central bank policies and economic indicators rather than stock-specific characteristics. Given this market backdrop, stock-specific sentiment insights detracted from relative return. In particular, an insight identifying informed investor sentiment based on short positions of hedge funds was the top individual detractor, given the significant hedge fundde-risking that occurred towards the end of 2018 as well as the sharp momentum drawdown experienced in September of this year. Another significant detractor within the Fund’s trend- and sentiment-based insights was a signal that captures sentiment through a machine-learned analysis of sell-side research reports. Elsewhere, insights evaluating company fundamentals struggled over much of the period, as investors focused on identifying speculative growth opportunities rather than companies with strong and improving fundamentals. Given this market environment, signals seeking to identify areas of relative value struggled significantly. Also among the portfolio’s fundamental signals, more traditional measures of company quality were challenged over the course of the year. The portfolio’s macro thematic insights also detracted from Fund performance, as certain industry timing signals left the portfolio on the wrong side of a number of market moves, most notably the sharp decline in interest rates experienced in the third quarter of 2019.

Though the Fund underperformed overall, there were certain bright spots among the Master Portfolio’s stock selection insights that provided some ballast to portfolio performance. While the portfolio’s trend-based insights were challenged throughout the period, a machine-learned signal conducting text-analysis of management conference calls to identify longer-term trends in company fundamentals was the top individual contributor. Similarly, although the portfolio’s fundamental insights detracted in aggregate, several alternative quality insights supported performance throughout the period, as investors sought out higher-quality companies with sustainable business models amid increasing market uncertainty. Among this group of insights, evaluating companies on long-term sustainability measures provided stability to the portfolio. Elsewhere, a signal gauging the sentiment of informed bond investors was also additive, as its defensive properties were rewarded toward the end of 2018 as well as during the temporary drawdowns experienced in the second and third quarters of 2019. Though the signal is included in the portfolio’s sentiment insights, it also provides an alternative lens into company quality, which helped support Fund returns.

Describe recent portfolio activity.

Over the course of the period, the Master Portfolio maintained a balanced allocation of risk across all major return drivers. However, a number of new stock selection insights were added to the portfolio. Among these was an insight that captures the location of hotel booking trends and invests in related stocks most sensitive to those areas. The investment adviser also added a machine-learned signal that pulls from several alternative data sources to try and more accurately gauge consumer transactions. In addition, an insight that evaluates trade volumes to determine broker concentration and identify overcrowded trades was introduced to the portfolio. Finally, the investment adviser improved upon an existing signal, expanding the data sources used to identify trends in company hiring as an indication of future company growth.

Describe portfolio positioning at period end.

Relative to the Russell 1000^® Index, the Master Portfolio was positioned essentially neutrally from a sector perspective. The Master Portfolio had slight overweight positions in the industrials and utilities sectors and slight underweight positions in the materials and energy sectors.

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.

For each class of the Fund, expenses are equal to the annualized expense ratio for the class, multiplied by the average account value over the period, multiplied by 183/365 (to reflect theone-half year period shown). Because the Fund invests all of its assets in the Master Portfolio, the expense table reflects the net expenses of both the Fund and the Master Portfolio in which it invests.

^(b)

Hypothetical 5% annual return before expenses is calculated by prorating the number of days in the most recent fiscal half year divided by 365. See “Disclosure of Expenses” on page 8 for further information on how expenses were calculated.

About Fund Performance

Institutional and Class K Sharesare not subject to any sales charge. These shares bear no ongoing distribution or service fees and are available only to certain eligible investors. Class K Shares performance shown prior to the Class K Shares inception date of January 25, 2018 is that of Institutional Shares. The performance of each Fund’s Class K Shares would be substantially similar to Institutional Shares because Class K Shares and Institutional Shares invest in the same portfolio of securities and performance would only differ to the extent that Class K Shares and Institutional Shares have different expenses. The actual returns of Class K Shares would have been higher than those of the Institutional Shares because Class K Shares have lower expenses than the Institutional Shares.

Service Sharesare not subject to any sales charge. These shares are subject to a service fee of 0.25% per year (but no distribution fee) and are only available to certain eligible investors.

Investor A Sharesare subject to a maximum initial sales charge(front-end load) of 5.25% and a service fee of 0.25% per year (but no distribution fee). Certain redemptions of these shares may be subject to a contingent deferred sales charge (“CDSC”) where no initial sales charge was paid at the time of purchase. These shares are generally available through financial intermediaries.

Investor C Sharesare subject to a 1.00% CDSC if redeemed within one year of purchase. In addition, these shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year. These shares are generally available through financial intermediaries. Effective November 8, 2018, the Funds adopted an automatic conversion feature whereby Investor C Shares held for approximately ten years will be automatically converted into Investor A Shares.

Class R Sharesare not subject to any sales charge. These shares are subject to a distribution fee of 0.25% per year and a service fee of 0.25% per year. These shares are available only to certain employer-sponsored retirement plans.

Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer towww.blackrock.comto obtain performance data current to the most recentmonth-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in the performance tables on the previous pages assume reinvestment of all distributions, if any, at net asset value ( “NAV” ) on theex-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. Distributions 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.

BlackRock Advisors, LLC (the “Administrator”), each Fund’s administrator, has contractually agreed to waive and/or reimburse a portion of each Fund’s expenses. Without such waiver and/or reimbursement, each Fund’s performance would have been lower. With respect to each Fund’s contractual waiver, the Administrator is under no obligation to continue waiving and/or reimbursing its fees after the applicable termination date of such agreement. See Note 4 of the Notes to Financial Statements for additional information on waivers and/or reimbursements.

Disclosure of Expenses

Shareholders of each Fund may incur the following charges: (a) transactional expenses, such as sales charges and (b) operating expenses, including administration fees, service and distribution fees, including12b-1 fees, acquired fund fees and expenses, and other fund expenses. The expense examples shown on the previous pages (which are based on a hypothetical investment of $1,000 invested on April 1, 2019 and held through September 30, 2019) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds.

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

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

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

Derivative Financial Instruments

Master Advantage Large Cap Core Portfolio and Master Advantage Large Cap Value Portfolio (the “Master Portfolios”) may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the instrument. The Master Portfolios’ successful use of a derivative financial instrument depends on the investment adviser’s ability to predict pertinent market movements accurately, which cannot be assured. The use of these instruments may result in losses greater than if they had not been used, may limit the amount of appreciation a Master Portfolio can realize on an investment and/or may result in lower distributions paid to shareholders. The Master Portfolios’ investments in these instruments, if any, are discussed in detail in the Notes to Financial Statements.

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

1.	*ORGANIZATION*

BlackRock Large Cap Series Funds, Inc. (the “Corporation”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as anopen-end management investment company. The Corporation is organized as a Maryland corporation. The following, each of which is a series of the Corporation, are referred to herein collectively as the “Funds” or individually as a “Fund”.


Fund Name	Herein Referred To As	Diversification Classification
BlackRock Advantage Large Cap Core Fund	Advantage Large Cap Core	Diversified
BlackRock Advantage Large Cap Value Fund	Advantage Large Cap Value	Diversified

The Funds seek to achieve their investment objectives by investing all of their assets in the corresponding series of Master Large Cap Series LLC (“Master LLC”): Master Advantage Large Cap Core Portfolio and Master Advantage Large Cap Value Portfolio (each, a “Master Portfolio” and together, the “Master Portfolios”). Master LLC is an affiliate of the Corporation. Each Master Portfolio has the same investment objective and strategies as its corresponding Fund. The value of each Fund’s investment in its corresponding Master Portfolio reflects each Fund’s proportionate interest in the net assets of the Master Portfolio. The performance of each Fund is directly affected by the performance of its corresponding Master Portfolio. At September 30, 2019, the percentage of each Master Portfolio owned by the corresponding Fund was 76.5% for Advantage Large Cap Core and 99.9% for Advantage Large Cap Value. The financial statements of the Master 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 offer multiple classes of shares. All classes of shares have identical voting, dividend, liquidation and other rights and are subject to the same terms and conditions, except that certain classes bear expenses related to the shareholder servicing and distribution of such shares. Institutional, Service and Class K Shares are sold only to certain eligible investors. Class R Shares are available only to certain employer-sponsored retirement plans. Investor A and Investor C Shares are generally available through financial intermediaries. Effective November 8, 2018, the Funds adopted an automatic conversion feature whereby Investor C Shares held for approximately ten years will be automatically converted into Investor A Shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor C shareholders may vote on material changes to the Investor A Shares distribution and service plan). The Board of Directors of the Corporation and Board of Directors of the Master LLC are referred to throughout this report as the “Board of Directors” or the “Board” and the members are referred to as “Directors.”


Share Class	Initial Sales Charge	CDSC			Conversion Privilege
Institutional, Service, Class K and Class R Shares	No		No		None
Investor A Shares	Yes		No	^(a)	None
Investor C Shares	No		Yes		To Investor A Shares after approximately 10 years

^(a)

Investor A Shares may be subject to a contingent deferred sales charge (“CDSC”) for certain redemptions where no initial sales charge was paid at the time of purchase.

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

Reorganization:The Board of Directors of the Corporation and the Board of Trustees of State Farm Mutual Fund Trust and shareholders of State Farm Equity Fund (the “Target Fund”) approved the reorganization of the Target Fund into Advantage Large Cap Core. As a result, Advantage Large Cap Core acquired all of the assets and assumed certain of the liabilities of the Target Fund in exchange for an equal aggregate value of newly-issued shares of Advantage Large Cap Core.

Each shareholder of the Target Fund received shares of Advantage Large Cap Core in an amount equal to the aggregate net asset value (“NAV”) of the shareholder’s Target Fund shares, as determined at the close of business on November 16, 2018.

On November 19, 2018, all of the portfolio securities previously held by the Target Fund were subsequently contributed by Advantage Large Cap Core to Master Advantage Large Cap Core Portfolio in exchange for an investment in Master Advantage Large Cap Core Portfolio.

The reorganization was accomplished by atax-free exchange of shares of Advantage Large Cap Core in the following amounts and at the following conversion ratios:


Target Fund’s Share Class	Shares Prior to Reorganization		Conversion Ratio		Advantage Large Cap Core’s Share Class		Shares of Advantage Large Cap Core
Class A		15,797,869		0.54503407		Investor A		8,610,377

The purpose of the transaction was to combine the assets of the Target Fund with the assets of Advantage Large Cap Core. The reorganization was atax-free event and was effective on November 19, 2018.

Assuming the reorganization had been completed on October 1, 2018, the beginning of the fiscal reporting period of Advantage Large Cap Core, the pro forma results of operations for the year ended September 30, 2019, are as follows:

•

Net investment income: $36,159,593

•

Net realized and change in unrealized loss on investments: $(11,434,372)

•

Net increase in net assets resulting from operations: $24,725,221

Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it is not practicable to separate the amounts of revenue and earnings of the Target Fund that have been included in Advantage Large Cap Core’s Statement of Operations since November 19, 2018.

Reorganization costs incurred by Advantage Large Cap Core in connection with the reorganization were expensed by Advantage Large Cap Core. The Manager reimbursed Advantage Large Cap Core $166,533, which is included in fees waived and/or reimbursed by the Manager in the Statements of Operations.

2.	*SIGNIFICANT ACCOUNTING POLICIES*

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

Investment Transactions and Income Recognition:For financial reporting purposes, contributions to and withdrawals from the Master Portfolios are accounted for on a trade date basis. Each Fund records its proportionate share of the Master Portfolio’s income, expenses and realized and unrealized gains and losses on a daily basis. Realized and unrealized gains and losses are adjusted utilizing partnership tax allocation rules. In addition, each Fund accrues its own expenses. Income, expenses and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets.

Distributions:Distributions paid by the Funds are recorded on theex-dividend date. Distributions of capital gains are recorded on theex-dividend date and made at least annually. The character and timing of distributions are determined in accordance with U.S. federal income tax regulations, which may differ from U.S. GAAP.

Offering Costs:Offering costs are amortized over a12-month period beginning with the commencement of operations of a class of shares.

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

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

3.	*INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS*

The Funds’ policy is to value their financial instruments at fair value. Each Fund records its investment in the Master Portfolio at fair value based on the Funds’ proportionate interest in the net assets of the Master Portfolio. Valuation of securities held by the Master Portfolio is discussed in Note 3 of the Master Portfolios’ Notes to Financial Statements, which are included elsewhere in this report.

Administration:The Corporation, on behalf of the Funds, entered into an Administration Agreement with the Administrator, an indirect, wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”), to provide administrative services (other than investment advice and related portfolio activities). For such services, each Fund pays the Administrator a monthly fee at an annual rate of 0.25% of the average daily net assets of the Fund. The Funds do not pay an investment advisory fee or investment management fee.

Service and Distribution Fees:The Corporation, on behalf of the Funds, entered into a Distribution Agreement and a Distribution Plan with BlackRock Investments, LLC (“BRIL”), an affiliate of the Administrator. Pursuant to the Distribution Plans and in accordance with Rule12b-1 under the 1940 Act, each Fund pays BRIL ongoing service and distribution fees.

Service Fee		0.25	%		0.25	%		0.25	%		0.25	%
Distribution Fee		—			—			0.75			0.25

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

For the year ended September 30, 2019, the following table shows the class specific service and distribution fees borne directly by each share class of each Fund:


	Service		Investor A		Investor C		Class R		Total

Expense Limitations, Waivers and Reimbursements:With respect to each Fund, the Administrator contractually agreed to waive and/or reimburse fees or expenses in order to limit expenses, excluding interest expense, dividend expense, tax expense, acquired fund fees and expenses and certain other fund expenses, which constitute extraordinary expenses not incurred in the ordinary course of each Fund’s business (“expense limitations”). The expense limitations as a percentage of average daily net assets are as follows:


	Advantage Large Cap Core			Advantage Large Cap Value
Institutional		0.48	%		0.54	%

Investor C		1.48			1.54

The Administrator has agreed not to reduce or discontinue these contractual expense limitations through January 31, 2021 for Advantage Large Cap Core and January 31, 2020 for Advantage Large Cap Value, unless approved by the Board, including a majority of the independent directors who are not “interested persons” of the Corporation, as defined in the 1940 Act (“Independent Directors”), or by a vote of a majority of the outstanding voting securities of a Fund. For the year ended September 30, 2019, the Administrator waived and/or reimbursed $6,625,259 and $1,760,504 for Advantage Large Cap Core and Advantage Large Cap Value, respectively, which is included in fees waived and/or reimbursed by the Administrator in the Statements of Operations.

	Institutional		Service		Investor A		Investor C		Class K		Class R		Total

The Funds have incurred expenses in connection with the realignment and consolidation of the boards of directors of certain BlackRock-advised funds. The Administrator has voluntarily agreed to reimburse certain Funds for all or a portion of such expenses, which amounts are included in fees waived and/or reimbursed by the Administrator in the Statements of Operations. For the year ended September 30, 2019, the amount reimbursed for Advantage Large Cap Core and Advantage Large Cap Value was $39,778 and $12,646, respectively.

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

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

During the year ended September 30, 2019, the Funds did not participate in the Interfund Lending Program.

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

5.	*INCOME TAX INFORMATION*

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

Each Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on each Fund’s U.S. federal tax returns generally remains open for each of the four years ended September 30, 2019. The statutes of limitations on each Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to the Funds as of September 30, 2019, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. As of period end, the following permanent differences attributable to thenon-deductible expenses was reclassified to the following accounts:


	Advantage Large Cap Core			Advantage Large Cap Value
Paid-in capital	$	(15,084	)	$	(15,084	)

9/30/18	$	490,197,695	$	10,761,819

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


	Advantage Large Cap Core		Advantage Large Cap Value
Undistributed ordinary income	$	34,166,621	$	8,561,648
Undistributed long-term capital gains		57,974,974		11,254,374

	$	375,897,895	$	60,604,314

The difference between book-basis andtax-basis net unrealized gains was attributable primarily to the timing of income recognition on partnership interests.

Report of Independent Registered Public Accounting Firm

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

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statements of assets and liabilities of BlackRock Advantage Large Cap Core Fund and BlackRock Advantage Large Cap Value Fund of BlackRock Large Cap Series Funds, Inc. (the “Funds”) as of September 30, 2019, 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, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Funds as of September 30, 2019, and 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 the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. 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, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

Notes to Financial Statements		Master Large Cap Series LLC

1.	*ORGANIZATION*

Master Advantage Large Cap Core Portfolio and Master Advantage Large Cap Value Portfolio (collectively, the “Portfolios” or individually, a “Portfolio”) are each a series of Master Large Cap Series LLC (the “Master LLC”). The Master LLC is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as anopen-end management investment company and is organized as a Delaware limited liability company. Each Portfolio is classified as diversified. The Limited Liability Company Agreement of the Master LLC permits the Board of Directors of the Master LLC (the “Board” and the members are referred to as “Directors”) to issuenon-transferable interests in the Master LLC, subject to certain limitations.

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

Reorganization:The Board of BlackRock Large Cap Series Fund, Inc. and the Board of Trustees of State Farm Mutual Fund Trust and shareholders of State Farm Equity Fund (the “Target Fund”) approved the reorganization of the Target Fund into BlackRock Advantage Large Cap Core Fund. As a result, BlackRock Advantage Large Cap Core Fund acquired all of the assets and assumed certain of the liabilities of the Target Fund in exchange for an equal aggregate value of newly-issued shares of BlackRock Advantage Large Cap Core Fund.

On November 19, 2018, all of the portfolio securities previously held by the Target Fund were subsequently contributed by BlackRock Advantage Large Cap Core Fund to the Portfolio in exchange for an investment in the Portfolio.

For financial reporting purposes, assets received and shares issued by BlackRock Advantage Large Cap Core Fund were recorded at fair value. However, the cost basis of the investments received from the Target Fund was carried forward by Master Advantage Large Cap Core Portfolio to align ongoing reporting of BlackRock Advantage Large Cap Core Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

The Target Fund’s fair value and cost of investments prior to the reorganization were as follows:


Target Fund	Fair Value of Investments		Cost of Investments
State Farm Equity Fund	$	369,010,639	$	345,412,676

2.	*SIGNIFICANT ACCOUNTING POLICIES*

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

Investment Transactions and Income Recognition:For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed. Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on theex-dividend date. Dividends from foreign securities where theex-dividend date may have passed are subsequently recorded when the Portfolios are informed of theex-dividend date. Under the applicable foreign tax laws, a withholding tax at various rates may be imposed on capital gains, dividends and interest. Upon notification from issuers, a portion of the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain.

Segregation and Collateralization:In cases where a Portfolio enters into certain investments (e.g., futures contracts) that would be treated as “senior securities” for 1940 Act purposes, the Portfolio may segregate or designate on its books and records cash or liquid assets having a market value at least equal to the amount of its future obligations under such investments. Doing so allows the investment to be excluded from treatment as a “senior security.” Furthermore, if required by an exchange or counterparty agreement, the Portfolio may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments or obligations.

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

Other:Expenses directly related to a Portfolio are charged to that Portfolio. Other operating expenses shared by several funds, including other funds managed by the Manager, are prorated among those funds on the basis of relative net assets or other appropriate methods.

Each Portfolio has an arrangement with its custodian whereby credits are earned on uninvested cash balances, which could be used to reduce custody fees and/or overdraft charges. Each Portfolio may incur charges on certain uninvested cash balances and overdrafts, subject to certain conditions.

3.	*INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS*

Investment Valuation Policies:The Portfolios’ investments are valued at fair value (also referred to as “market value” within the financial statements) 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 Portfolios would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Portfolios determine the fair values of their financial instruments using various independent dealers or pricing services under policies approved by the Board. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to oversee the pricing function for all financial instruments.

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

Fair Value Inputs and Methodologies:The following methods and inputs are used to establish the fair value of each Portfolio’s assets and liabilities:

•

Equity investments traded on a recognized securities exchange are valued at the official closing price each day, if available. For equity investments traded on more than one exchange, the official closing price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange for which there were no sales on that day may be valued at the last available bid (long positions) or ask (short positions) price.

•

Generally, trading in foreign instruments is substantially completed each day at various times prior to the close of trading on the NYSE. Occasionally, events affecting the values of such instruments may occur between the foreign market close and the close of trading on the NYSE that may not be reflected in the computation of the Portfolios’ net assets. Each business day, the Portfolios use a pricing service to assist with the valuation of certain foreign exchange-traded equity securities and foreign exchange-traded andover-the-counter (“OTC”) options (the “Systematic Fair Value Price”). Using current market factors, the Systematic Fair Value Price is designed to value such foreign securities and foreign options at fair value as of the close of trading on the NYSE, which follows the close of the local markets.

•

Investments inopen-end U.S. mutual funds are valued at NAV each business day.

•

The Portfolios value their investment in SL Liquidity Series, LLC, Money Market Series (the “Money Market Series”) at fair value, which is ordinarily based upon their pro rata ownership in the underlying fund’s net assets. The Money Market Series seeks current income consistent with maintaining liquidity and preserving capital. Although the Money Market Series is not registered under the 1940 Act, its investments may follow the parameters of investments by a money market fund that is subject to Rule2a-7 under the 1940 Act.

•

Futures contracts traded on exchanges are valued at their last sale price.

If events (e.g., a company announcement, market volatility or a natural disaster) occur that are expected to materially affect the value of such investments, or in the event that the application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, or its delegate, in accordance with a policy approved by the Board as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee will include market approach, income approach and cost approach. Valuation techniques such as discounted cash flow, use of market comparables and matrix pricing are types of valuation approaches and are typically used in determining fair value. When determining the price for Fair Valued Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that each Portfolio might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in anarm’s-length transaction. Fair value determinations shall be based upon all available factors that the Global Valuation Committee, or its delegate, deems relevant and consistent with the principles of fair value measurement. The pricing of all Fair Valued Investments is subsequently reported to the Board or a committee thereof on a quarterly basis.

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

•

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

•

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

•

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

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. Investments classified within Level 3 have significant unobservable inputs used by the Global Valuation Committee in determining the price for Fair Valued Investments. Level 3 investments include equity or debt issued by privately held companies or funds. There may not be a secondary market, and/or there are a limited number of investors. The categorization of a value determined for investments and derivative financial instruments is based on the pricing transparency of the investments and derivative financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

As of September 30, 2019, certain investments of the Portfolios were valued using NAV per share (or its equivalent) as no quoted market value is available and therefore have been excluded from the fair value hierarchy.

4.	*SECURITIES AND OTHER INVESTMENTS*

Securities Lending:Each Portfolio may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Portfolios collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. Government. The initial collateral received by each Portfolio is required to have a value of at least 102% of the current value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current market value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Portfolio and any additional required collateral is delivered to the Portfolio, or excess collateral returned by the Portfolio, on the next business day. During the term of the loan, each Portfolio is entitled to all distributions made on or in respect of the loaned securities, but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

The market value of any securities on loan, all of which were classified as common stocks in the Portfolios’ Schedules of Investments, and the value of any related collateral are shown separately in the Statements of Assets and Liabilities as a component of investments at value — unaffiliated, and collateral on securities loaned at value, respectively.


N O T E S T O F I N A N C I A L S T A T E M E N T S			51


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

As of period end, any securities on loan were collateralized by cash and/or U.S. Government obligations. Cash collateral invested by the securities lending agent, BlackRock Investment Management, LLC (“BIM”), if any, is disclosed in the Schedules of Investments.

Securities lending transactions are entered into by the Portfolios under Master Securities Lending Agreements (each, an “MSLA”), which provide the right, in the event of default (including bankruptcy or insolvency), for thenon-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Portfolios, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, absent an event of default, the borrower can resell orre-pledge the loaned securities, and a Portfolio can reinvest cash collateral received in connection with loaned securities. Upon an event of default, the parties’ obligations to return the securities or collateral to the other party are extinguished, and the parties can resell orre-pledge the loaned securities or the collateral received in connection with the loaned securities in order to satisfy the defaulting party’s net payment obligation for all transactions under the MSLA. The defaulting party remains liable for any deficiency.

As of period end, the following tables are a summary of the Portfolios’ securities lending agreements by counterparty which are subject to offset under an MSLA:

^(a)

Collateral received in excess of the market value of securities on loan is not presented in this table. The total cash collateral received by each Portfolio is disclosed in the Portfolio’s Statements of Assets and Liabilities.

^(b)

The market value of the loaned securities is determined as of September 30, 2019. Additional collateral is delivered to the Portfolio on the next business day in accordance with the MSLA. The net amount would be subject to the borrower default indemnity in the event of default by the counterparty.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Portfolios benefit from a borrower default indemnity provided by BIM. BIM’s indemnity allows for full replacement of the securities loaned to the extent the collateral received does not cover the value on the securities loaned in the event of borrower default. Each Portfolio could incur a loss if the value of an investment purchased with cash collateral falls below the market value of loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by the Portfolios.

5.	*DERIVATIVE FINANCIAL INSTRUMENTS*

The Portfolios engage in various portfolio investment strategies using derivative contracts both to increase the returns of the Portfolios and/or to manage their exposure to certain risks such as credit risk, equity risk, interest rate risk, foreign currency exchange rate risk, commodity price risk or other risks (e.g., inflation risk). Derivative financial instruments categorized by risk exposure are included in the Schedules of Investments. These contracts may be transacted on an exchange or OTC.

Futures Contracts:Futures contracts are purchased or sold to gain exposure to, or manage exposure to, changes in interest rates (interest rate risk) and changes in the value of equity securities (equity risk) or foreign currencies (foreign currency exchange rate risk).

Futures contracts are agreements between the Portfolios and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and on a specified date. Depending on the terms of a contract, it is settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash amount on the settlement date. Upon entering into a futures contract, the Portfolios are required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on a contract’s size and risk profile. The initial margin deposit must then be maintained at an established level over the life of the contract. Amounts pledged, which are considered restricted, are included in cash pledged for futures contracts in the Statements of Assets and Liabilities.

Securities deposited as initial margin are designated in the Schedules of Investments and cash deposited, if any, are shown as cash pledged for futures contracts in the Statements of Assets and Liabilities. Pursuant to the contract, the Portfolios agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in


52		2 0 1 9 B L A C K R O C K A N N U A L R E P O R T T O S H A R E H O L D E R S


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

market value of the contract (“variation margin”). Variation margin is recorded as unrealized appreciation (depreciation) and, if any, shown as variation margin receivable (or payable) on futures contracts in the Statements of Assets and Liabilities. When the contract is closed, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the notional amount of the contract at the time it was opened and the notional amount at the time it was closed. The use of futures contracts involves the risk of an imperfect correlation in the movements in the price of futures contracts and interest, foreign currency exchange rates or underlying assets.

Collateral Requirements:For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting themark-to-market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Portfolio and the counterparty.

Cash collateral that has been pledged to cover obligations of the Portfolios and cash collateral received from the counterparty, if any, is reported separately in the Statements of Assets and Liabilities as cash pledged as collateral and cash received as collateral, respectively.Non-cash collateral pledged by the Portfolios, if any, is noted in the Schedules of Investments. Generally, the amount of collateral due from or to a counterparty is subject to a certain minimum transfer amount threshold before a transfer is required, which is determined at the close of business of the Portfolios. Any additional required collateral is delivered to/pledged by the Portfolios on the next business day. Typically, the counterparty is not permitted to sell,re-pledge or use cash andnon-cash collateral it receives. A Portfolio generally agrees not to usenon-cash collateral that it receives but may, absent default or certain other circumstances defined in the underlying ISDA Master Agreement, be permitted to use cash collateral received. In such cases, interest may be paid pursuant to the collateral arrangement with the counterparty. To the extent amounts due to the Portfolios from their counterparties are not fully collateralized, they bear the risk of loss from counterpartynon-performance. Likewise, to the extent the Portfolios have delivered collateral to a counterparty and stand ready to perform under the terms of their agreement with such counterparty, they bear the risk of loss from a counterparty in the amount of the value of the collateral in the event the counterparty fails to return such collateral. Based on the terms of agreements, collateral may not be required for all derivative contracts.

For financial reporting purposes, the Portfolios do not offset derivative assets and derivative liabilities that are subject to netting arrangements, if any, in the Statements of Assets and Liabilities.

6.	*INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES*

Investment Advisory:The Master LLC, on behalf of each Portfolio, entered into an Investment Advisory Agreement with the Manager, the Portfolios’ investment adviser and an indirect, wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”), to provide investment advisory and administrative services. The Manager is responsible for the management of each Portfolio’s portfolio and provides the personnel, facilities, equipment and certain other services necessary to the operations of each Portfolio.

For such services, each Portfolio pays the Manager a monthly fee at an annual rate equal to the average daily value of each Portfolio’s net assets at the following annual rates:

Master Advantage Large Cap Core Portfolio


Average Daily Net Assets	Investment Advisory Fee
First $1 Billion		0.45	%
$1 Billion — $2 Billion		0.42
$2 Billion — $3 Billion		0.41
$3 Billion — $10 Billion		0.39
Greater than $10 Billion		0.38

Master Advantage Large Cap Value Portfolio


Average Daily Net Assets	Investment Advisory Fee
First $1 Billion		0.49	%
$1 Billion — $2 Billion		0.46
$2 Billion — $3 Billion		0.44
$3 Billion — $10 Billion		0.43
Greater than $10 Billion		0.42

Expense Limitations, Waivers and Reimbursements:With respect to the Portfolios, the Manager voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees each Portfolio pays to the Manager indirectly through its investment in affiliated money market funds (the “affiliated money market fund waiver”). These amounts are included in fees waived and/or reimbursed by the Manager in the Statements of Operations. For the year ended September 30, 2019, the amounts waived were as follows:


Master Advantage Large Cap Core Portfolio	$	24,606
Master Advantage Large Cap Value Portfolio		4,376

The Manager has contractually agreed to waive its investment advisory fee with respect to any portion of each Portfolio’s assets invested in affiliated equity and fixed-income mutual funds and affiliated exchange-traded funds that have a contractual management fee through January 31, 2021 for Advantage Large Cap Core and January 31, 2020 for Advantage Large Cap Value. The contractual agreement may be terminated upon 90 days’ notice by a majority of the independent directors who are not “interested persons” of the Master LLC, as defined in the 1940 Act (“Independent Directors”), or by a vote of a majority of the outstanding voting securities of a Portfolio. For the year ended September 30, 2019, there were no fees waived and/or reimbursed by the Manager pursuant to this arrangement.

The Manager has also voluntarily agreed to waive its investment advisory fees to enable the feeders that invest in the Portfolios to limit expenses, if applicable. The Manager may discontinue this voluntary waiver at any time. The amount waived is included in fees waived and/or reimbursed by the Manager in the Statements of Operations. For the year ended September 30, 2019, the amounts waived and/or reimbursed were:


Master Advantage Large Cap Core Portfolio	$	380,542
Master Advantage Large Cap Value Portfolio		200,285

For the year ended September 30, 2019, the Portfolios reimbursed the Manager for certain accounting services, which is included in accounting services in the Statements of Operations. The reimbursements were as follows:


Master Advantage Large Cap Core Portfolio	$	41,081
Master Advantage Large Cap Value Portfolio		6,945

Securities Lending:The U.S. Securities and Exchange Commission (“SEC”) has issued an exemptive order which permits BIM, an affiliate of the Manager, to serve as securities lending agent for the Portfolios, subject to applicable conditions. As securities lending agent, BIM bears all operational costs directly related to securities lending. The Portfolios are responsible for expenses in connection with the investment of cash collateral received for securities on loan (the “collateral investment expenses”). The cash collateral is invested in a private investment company managed by the Manager or its affiliates. However, BIM has agreed to cap the collateral investment expenses of the private investment company to an annual rate of 0.04%. The investment adviser to the private investment company will not charge any advisory fees with respect to shares purchased by the Portfolios. The private investment company in which the cash collateral has been invested may, under certain circumstances, impose a liquidity fee of up to 2% of the value withdrawn or temporarily restrict withdrawals for up to 10 business days during a 90 day period, in the event that the private investment company’s weekly liquid assets fall below certain thresholds.

Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment expenses. Each Portfolio retains a portion of securities lending income and remits a remaining portion to BIM as compensation for its services as securities lending agent.

Pursuant to the current securities lending agreement, each Portfolio retains 73.5% of securities lending income (which excludes collateral investment expenses), and this amount retained can never be less than 70% of the total of securities lending income plus the collateral investment expenses.

In addition, commencing the business day following the date that the aggregate securities lending income earned across the BlackRock Multi-Asset Complex in a calendar year exceeds a specified threshold, each Portfolio, pursuant to the securities lending agreement, will retain for the remainder of that calendar year securities lending income in an amount equal to 80% of securities lending income (which excludes collateral investment expenses), and this amount retained can never be less than 70% of the total of securities lending income plus the collateral investment expenses.

Prior to January 1, 2019, each Portfolio retained 71.5% of securities lending income (which excluded collateral investment expenses) and the amount retained could never be less than 65% of the total of securities lending income plus the collateral investment expenses. In addition, commencing the business day following the date that the aggregate securities lending income earned across a complex ofopen-end funds referred to as the Equity-Liquidity Complex in a calendar year exceeded a specified threshold, the Fund would retain for the remainder of that calendar year 75% of securities lending income (which excluded collateral investment expenses), and the amount retained could never be less than 65% of the total of securities lending income plus the collateral investment expenses.

The share of securities lending income earned by each Portfolio is shown as securities lending income – affiliated – net in the Statements of Operations. For the year ended September 30, 2019, each Portfolio paid BIM the following amounts for securities lending agent services:


Master Advantage Large Cap Core Portfolio	$	72,340
Master Advantage Large Cap Value Portfolio		6,451

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

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

During the year ended September 30, 2019, the Portfolios did not participate in the Interfund Lending Program.

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

7.	*PURCHASES AND SALES*

For the year ended September 30, 2019, purchases and sales of investments, excluding short-term securities, were as follows:


	Master Advantage Large Cap Core Portfolio		Master Advantage Large Cap Value Portfolio
Purchases		$4,982,192,113		$ 990,273,826
Sales		5,005,336,526		1,011,054,567

8.	*INCOME TAX INFORMATION*

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

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

Each Portfolio files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on each Portfolio’s U.S. federal tax returns generally remains open for each of the four years ended September 30, 2019. The statutes of limitations on each Portfolio’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 Portfolios as of September 30, 2019, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Portfolios’ financial statements.

As of September 30, 2019, gross unrealized appreciation and depreciation for investments and derivatives based on cost for U.S. federal income tax purposes were as follows:


	Master Advantage Large Cap Core Portfolio			Master Advantage Large Cap Value Portfolio
Tax cost		$3,101,718,360			$581,733,181

Gross unrealized appreciation		$ 438,386,466			$ 65,441,459
Gross unrealized depreciation		(50,243,432	)		(14,351,454	)

Net unrealized appreciation		$ 388,143,034			$ 51,090,005

9.	*BANK BORROWINGS*

The Master LLC, on behalf of the Portfolios, along with certain other funds managed by the Manager and its affiliates (“Participating Funds”), is a party to a364-day, $2.25 billion credit agreement with a group of lenders. Under this agreement, the Portfolios may borrow to fund shareholder redemptions. Excluding commitments designated for certain individual funds, the Participating Funds, including the Portfolios, can borrow up to an aggregate commitment amount of $1.75 billion at any time outstanding, subject to asset coverage and other limitations as specified in the agreement. The credit agreement has the following terms: a fee of 0.10% per annum on unused commitment amounts and interest at a rate equal to the higher of(a) one-month LIBOR (but, in any event, not less than 0.00%) on the date the loan is made plus 0.80% per annum or (b) the Fed Funds rate (but, in any event, not less than 0.00%) in effect from time to time plus 0.80% per annum on amounts borrowed. The agreement expires in April 2020 unless extended or renewed. Prior to April 18, 2019, Participating Funds paid an upfront commitment fee of 0.02% on the total commitment amounts, in addition to administration, legal and arrangement fees, which are included in miscellaneous expenses in the Statements of Operations. These fees were allocated among such funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. During the year ended September 30, 2019, the Portfolios did not borrow under the credit agreement.

10.

PRINCIPAL RISKS

In the normal course of business, certain Portfolios invest in securities or other instruments and may enter into certain transactions, and such activities subject each Portfolio to various risks, including among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate and price fluctuations. Each Portfolio’s prospectus provides details of the risks to which each Portfolio is subject.

The Portfolios may be exposed to additional risks when reinvesting cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00, which may be subject to redemption gates or liquidity fees under certain circumstances.

Valuation Risk:The market values of equities, such as common stocks and preferred securities or equity related investments, such as futures and options, may decline due to general market conditions which are not specifically related to a particular company. They may also decline due to factors which affect a particular industry or industries.APortfolio may invest in illiquid investments. An illiquid investment is any investment that a Portfolio reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.APortfolio may experience difficulty in selling illiquid investments in a timely manner at the price that it believes the investments are worth. Prices may fluctuate widely over short or extended periods in response to company, market or


N O T E S T O F I N A N C I A L S T A T E M E N T S			55


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

economic news. Markets also tend to move in cycles, with periods of rising and falling prices. This volatility may cause each Portfolio’s NAV to experience significant increases or decreases over short periods of time. If there is a general decline in the securities and other markets, the NAV of a Portfolio may lose value, regardless of the individual results of the securities and other instruments in which a Portfolio invests.

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

A derivative contract may suffer amark-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract.

With futures, there is less counterparty credit risk to the Portfolios since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, a Portfolio does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default (including the bankruptcy or insolvency). Additionally, credit risk exists in exchange-traded futures with respect to initial and variation margin that is held in a clearing broker’s customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients, typically the shortfall would be allocated on a pro rata basis across all the clearing broker’s customers, potentially resulting in losses to the Portfolios.

SUBSEQUENT EVENTS

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

On November 13, 2019, the Board approved a change in the fiscalyear-end of Master Advantage Large Cap Value Portfolio, effective as of May 31, 2020, from September 30 to May 31.

Disclosure of Investment Advisory Agreement

The Board of Directors of Master Large Cap Series LLC (the “Master LLC”) met in person on April 17, 2019 (the “April Meeting”) and May14-15, 2019 (the “May Meeting”) to consider the approval of the investment advisory agreement (the “Agreement”) between the Master LLC, on behalf of Master Advantage Large Cap Core Portfolio and Master Advantage Large Cap Value Portfolio (each, a “Master Portfolio” and together, the “Master Portfolios”), each a series of the Master LLC, and BlackRock Advisors, LLC (the “Manager” or “BlackRock”), the Master LLC’s investment advisor. Each of BlackRock Advantage Large Cap Core Fund and BlackRock Advantage Large Cap Value Fund (each, a “Fund” and together, the “Funds”), each a series of BlackRock Large Cap Series Funds, Inc. (the “Corporation”), is a “feeder” fund that invests all of its investable assets in the corresponding Master Portfolio. Accordingly, the Board of Directors of the Corporation also considered the approval of the Agreement with respect to the Master Portfolios. For simplicity: (a) the Board of Directors of the Master LLC and the Board of Directors of the Corporation are referred to herein collectively as the “Board,” and the members are referred to as “Board Members;” and (b) the shareholders of the Funds and the interest holders of the Master Portfolios are referred to as “shareholders.”

Activities and Composition of the Board

On the date of the May Meeting, the Board consisted of fifteen individuals, thirteen of whom were not “interested persons” of the Master LLC or the Corporation as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”). The Board Members are responsible for the oversight of the operations of the Master LLC or the Corporation, as pertinent, and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Board Members have retained independent legal counsel to assist them in connection with their duties. The Chair of the Board is an Independent Board Member. The Board has established five standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Ad Hoc Topics Committee, each of which is chaired by an Independent Board Member and composed of Independent Board Members (except for the Ad Hoc Topics Committee, which also has one interested Board Member).

The Agreement

Consistent with the requirements of the 1940 Act, the Board considers the continuation of the Agreement on an annual basis. The Board has four quarterly meetings per year, each typically extending for two days, and additionalin-person and telephonic meetings throughout the year, as needed. While the Board also has a fifthone-day meeting to consider specific information surrounding the renewals of the Agreement, the Board’s consideration entails a year-long deliberative process whereby the Board and its committees assess BlackRock’s services to each Fund. In particular, the Board assessed, among other things, the nature, extent and quality of the services provided to the Master Portfolios and the Funds by BlackRock, BlackRock’s personnel and affiliates, including (as applicable) investment management; accounting, administrative and shareholder services; oversight of the Master Portfolio and Fund service providers; risk management and oversight; legal and compliance services; and ability to meet applicable legal and regulatory requirements. Throughout the year, including during the contract renewal process, the Independent Board Members were advised by independent legal counsel, and met with independent legal counsel in various executive sessions outside of the presence of management.

During the year, the Board, acting directly and through its committees, considers information that is relevant to its annual consideration of the renewal of the Agreement, including the services and support provided by BlackRock to the Master Portfolios, the Funds and their shareholders. BlackRock also furnished additional information to the Board in response to specific questions from the Board. This additional information is discussed further below in the section titled “Board Considerations in Approving the Agreement.” Among the matters the Board considered were: (a) investment performance forone-year, three-year, five-year,ten-year and/or since inception periods, as applicable, against peer funds, applicable benchmark, and performance metrics, as applicable, as well as senior management’s and portfolio managers’ analyses of the reasons for any over-performance or under-performance relative to its peers, benchmarks, and other performance metrics, as applicable; (b) fees, including advisory, administration, if applicable, and other amounts paid to BlackRock and its affiliates by the Master Portfolios and/or the Funds for services; (c) each Master Portfolio’s and/or Fund’s operating expenses and how BlackRock allocates expenses to the Master Portfolios and the Funds; (d) the resources devoted to, risk oversight of, and compliance reports relating to, implementation of each Master Portfolio’s and each Fund’s investment objective(s), policies and restrictions, and meeting regulatory requirements; (e) BlackRock and the Master LLC’s and the Corporation’s adherence to applicable compliance policies and procedures; (f) the nature, character and scope ofnon-investment management services provided by BlackRock and its affiliates and the estimated cost of such services; (g) BlackRock’s and other service providers’ internal controls and risk and compliance oversight mechanisms; (h) BlackRock’s implementation of the proxy voting policies approved by the Board; (i) the use of brokerage commissions and execution quality of portfolio transactions; (j) BlackRock’s implementation of the Master LLC’s and/or the Corporation’s valuation and liquidity procedures; (k) an analysis of management fees for products with similar investment mandates across theopen-end fund, exchange-traded fund (“ETF”),closed-end fund,sub-advised mutual fund, separately managed account, collective investment trust, and institutional separate account product channels, as applicable, and the similarities and differences between these products and the services provided as compared to the Master Portfolios and/or the Funds; (l) BlackRock’s compensation methodology for its investment professionals and the incentives and accountability it creates, along with investment professionals’ investments in the fund(s) they manage; and (m) periodic updates on BlackRock’s business.

Board Considerations in Approving the Agreement

The Approval Process:Prior to the April Meeting, the Board requested and received materials specifically relating to the Agreement. The Independent Board Members are continuously engaged in a process with their independent legal counsel and BlackRock to review the nature and scope of the information provided to better assist its deliberations. The materials provided in connection with the April Meeting included, among other things: (a) information independently compiled and prepared by Broadridge Financial Solutions, Inc. (“Broadridge”) based on either a Lipper classification or Morningstar category, regarding the fees and expenses of each Master Portfolio and Fund, as applicable, as compared with a peer group of funds as determined by Broadridge (“Expense Peers”) and the investment performance of each Fund as compared with a peer group of funds (“Performance Peers”) and other metrics, as applicable; (b) information on the composition of the Expense Peers and Performance Peers, and a description of Broadridge’s methodology; (c) information on the estimated profits realized by BlackRock and its affiliates pursuant to the Agreement and a discussion offall-out benefits to BlackRock and its affiliates; (d) a general analysis provided by BlackRock concerning investment management fees received in connection with other types of investment products, such as institutional accounts,sub-advised mutual funds, ETFs,closed-end funds,open-end funds and separately managed accounts under similar investment mandates, as well as the performance of such other products, as applicable; (e) review ofnon-management fees; (f) the existence, impact and sharing of potential economies of scale, if any, with the Master Portfolios and the Funds; (g) a summary of aggregate amounts paid by each Master Portfolio and/or Fund to BlackRock; (h) sales and redemption data regarding each Fund’s shares; and (i) various additional information requested by the Board as appropriate regarding BlackRock’s, the Master Portfolios’ and the Funds’ operations.

Disclosure of Investment Advisory Agreement (continued)

At the April Meeting, the Board reviewed materials relating to its consideration of the Agreement. As a result of the discussions that occurred during the April Meeting, and as a culmination of the Board’s year-long deliberative process, the Board presented BlackRock with questions and requests for additional information. BlackRock responded to these requests with additional written information in advance of the May Meeting.

At the May Meeting, the Board concluded its assessment of, among other things: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of each Master Portfolio and each Fund as compared with the Performance Peers and other metrics, as applicable; (c) the advisory fee and the estimated cost of the services and estimated profits realized by BlackRock and its affiliates from their relationship with the Master Portfolios and the Funds; (d) each Fund’s fees and expenses compared to Expense Peers; (e) the sharing of potential economies of scale;(f) fall-out benefits to BlackRock and its affiliates as a result of BlackRock’s relationship with the Master Portfolios and the Funds; and (g) other factors deemed relevant by the Board Members.

The Board also considered other matters it deemed important to the approval process, such as other payments made to BlackRock or its affiliates relating to securities lending and cash management, and BlackRock’s services related to the valuation and pricing of portfolio holdings of each Master Portfolio. The Board noted the willingness of BlackRock personnel to engage in open, candid discussions with the Board. The Board did not identify any particular information as determinative, and each Board Member may have attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services Provided by BlackRock:The Board, including the Independent Board Members, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services and the resulting performance of each Fund. Throughout the year, the Board compared each Fund’s performance to the performance of a comparable group of mutual funds, relevant benchmark, and performance metrics, as applicable. The Board met with BlackRock’s senior management personnel responsible for investment activities, including the senior investment officers. The Board also reviewed the materials provided by each Master Portfolio’s portfolio management team discussing the Master Portfolio’s performance and the Master Portfolio’s investment objective(s), strategies and outlook.

The Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and each Master Portfolio’s portfolio management team; BlackRock’s research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of technology; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also considered BlackRock’s overall risk management program, including the continued efforts of BlackRock and its affiliates to address cybersecurity risks and the role of BlackRock’s Risk & Quantitative Analysis Group. The Board engaged in a review of BlackRock’s compensation structure with respect to each Master Portfolio’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent and create performance incentives.

In addition to investment advisory services, the Board considered the nature and quality of the administrative and othernon-investment advisory services provided to each Master Portfolio and Fund. BlackRock and its affiliates provide the Master Portfolios and the Funds with certain administrative, shareholder and other services (in addition to any such services provided to the Master Portfolios and the Funds by third parties) and officers and other personnel as are necessary for the operations of the Master Portfolios and the Funds. In particular, BlackRock and its affiliates provide the Master Portfolios and the Funds with administrative services including, among others: (i) responsibility for disclosure documents, such as the prospectus, the summary prospectus (as applicable), the statement of additional information and periodic shareholder reports; (ii) oversight of daily accounting and pricing; (iii) responsibility for periodic filings with regulators; (iv) overseeing and coordinating the activities of other service providers, including, among others, the custodian, fund accountant, transfer agent, and auditor for the Master Portfolios and the Funds, as applicable; (v) organizing Board meetings and preparing the materials for such Board meetings; (vi) providing legal and compliance support; (vii) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as the merger, consolidation or repurposing of certainopen-end funds; and (viii) performing or managing administrative functions necessary for the operation of the Master Portfolios and the Funds, such as tax reporting, expense management, fulfilling regulatory filing requirements, overseeing the Funds’ distribution partners, and shareholder call center and other services. The Board reviewed the structure and duties of BlackRock’s fund administration, shareholder services, and legal & compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations.

B. The Investment Performance of the Master Portfolios, the Funds and BlackRock:The Board, including the Independent Board Members, also reviewed and considered the performance history of each Master Portfolio and Fund, as applicable. The Board noted that each Fund’s investment results correspond directly to the investment results of the corresponding Master Portfolio. In preparation for the April Meeting, the Board was provided with reports independently prepared by Broadridge, which included a comprehensive analysis of each Fund’s performance as of December 31, 2018. Broadridge ranks funds in quartiles, ranging from first to fourth, where first is the most desirable quartile position and fourth is the least desirable. In connection with its review, the Board received and reviewed information regarding the investment performance of each Fund as compared to its Performance Peers. The Board and its Performance Oversight Committee regularly review, and meet with the management of each Master Portfolio to discuss, the performance of the Master Portfolio and the corresponding Fund, as applicable, throughout the year.

In evaluating performance, the Board focused particular attention on funds with less favorable performance records. The Board also noted that while it found the data provided by Broadridge generally useful, it recognized the limitations of such data, including in particular, that notable differences may exist between a fund and the Performance Peer funds (for example, the investment objective(s) and investment strategies). Further, the Board recognized that the performance data reflects a snapshot of a period as of a particular date and that selecting a different performance period could produce significantly different results. The Board also acknowledged that long-term performance could be impacted by even one period of significant outperformance or underperformance, and that a single investment theme could have the ability to affect long-term performance disproportionately.

The Board noted that for each of theone-, three- and five-year periods reported, BlackRockAdvantage Large Cap Core Fund ranked in the second quartile against its Performance Peers.

The Board noted that for each of theone-, three- and five-year periods reported, BlackRockAdvantage Large Cap Value Fund ranked in the second quartile against its Performance Peers.

C. Consideration of the Advisory/Management Fees and the Estimated Cost of the Services and Estimated Profits Realized by BlackRock and its Affiliates from their Relationship with the Master Portfolios and the Funds:The Board, including the Independent Board Members, reviewed each Master Portfolio’s/Fund’s contractual management fee rate compared with those of the Fund’s Expense Peers. The contractual management fee rate represents a combination of the advisory fee and any administrative fees, before taking into account any reimbursements or fee waivers. The Board also compared each Fund’s total expense ratio, as well as each Master Portfolio’s/Fund’s


D I S C L O S U R E O F I N V E S T M E N T A D V I S O R Y A G R E E M E N T			59

Disclosure of Investment Advisory Agreement (continued)

actual management fee rate, to those of the Fund’s Expense Peers. The total expense ratio represents a fund’s total net operating expenses, including any12b-1 or non12b-1 service fees. The total expense ratio gives effect to any expense reimbursements or fee waivers that benefit a fund, and the actual management fee rate gives effect to any management fee reimbursements or waivers that benefit a fund. The Board considered the services provided and the fees charged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts andsub-advised mutual funds (including mutual funds sponsored by third parties).

The Board received and reviewed statements relating to BlackRock’s financial condition. The Board reviewed BlackRock’s profitability methodology and was also provided with an estimated profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to the Master Portfolios and the Funds. The Board reviewed BlackRock’s estimated profitability with respect to the relevant Master Portfolio and Fund, as applicable, and other funds the Board currently oversees for the year ended December 31, 2018 compared to available aggregate estimated profitability data provided for the prior two years. The Board reviewed BlackRock’s estimated profitability with respect to certain other U.S. fund complexes managed by the Manager and/or its affiliates. The Board reviewed BlackRock’s assumptions and methodology of allocating expenses in the estimated profitability analysis, noting the inherent limitations in allocating costs among various advisory products. The Board recognized that profitability may be affected by numerous factors including, among other things, fee waivers and expense reimbursements by the Manager, the types of funds managed, precision of expense allocations and business mix. The Board thus recognized that calculating and comparing profitability at individual fund levels is difficult.

The Board noted that, in general, individual fund or product line profitability of other advisors is not publicly available. The Board reviewed BlackRock’s overall operating margin, in general, compared to that of certain other publicly-traded asset management firms. The Board considered the differences between BlackRock and these other firms, including the contribution of technology at BlackRock, BlackRock’s expense management, and the relative product mix.

In addition, the Board considered the estimated cost of the services provided to the Master Portfolios and the Funds by BlackRock, and BlackRock’s and its affiliates’ estimated profits relating to the management of the Master Portfolios and the Funds and the other funds advised by BlackRock and its affiliates. As part of its analysis, the Board reviewed BlackRock’s methodology in allocating its costs of managing the Master Portfolios and the Funds, to the relevant Master Portfolio or Fund, as pertinent. The Board considered whether BlackRock has the financial resources necessary to attract and retain high quality investment management personnel to perform its obligations under the Agreement and to continue to provide the high quality of services that is expected by the Board. The Board further considered factors including but not limited to BlackRock’s commitment of time, assumption of risk and liability profile in servicing the Master Portfolios and the Funds in contrast to what is required of BlackRock with respect to other products with similar investment mandates across theopen-end fund, ETF,closed-end fund,sub-advised mutual fund, separately managed account, collective investment trust, and institutional separate account product channels, as applicable.

The Board noted that the Master Advantage Large Cap Core Portfolio’s/BlackRock Advantage Large Cap Core Fund’s contractual management fee rate ranked in the second quartile, and that the actual management fee rate and the Fund’s total expense ratio each ranked in the first quartile relative to the Fund’s Expense Peers. The Board also noted that the Master Portfolio has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of the Master Portfolio increases above certain contractually specified levels. The Board noted that if the size of the Fund were to decrease, the Fund could lose the benefit of one or more breakpoints. The Board further noted that BlackRock and the Board have contractually agreed to a cap on the Fund’s total expenses as a percentage of the Fund’s average daily net assets on aclass-by-class basis.

The Board noted that the Master Advantage Large Cap Value Portfolio’s/BlackRock Advantage Large Cap Value Fund’s contractual management fee rate of ranked in the third quartile, and that the actual management fee rate and the Fund’s total expense ratio each ranked in the first quartile relative to the Fund’s Expense Peers. The Board also noted that the Master Portfolio has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of the Master Portfolio increases above certain contractually specified levels. The Board noted that if the size of the Fund were to decrease, the Fund could lose the benefit of one or more breakpoints. In addition, the Board noted that BlackRock and the Board have contractually agreed to a cap on the Fund’s total expenses as a percentage of the Fund’s average daily net assets on aclass-by-class basis.

D. Economies of Scale:The Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of the Master Portfolios and the Funds increase, including the existence of fee waivers and/or expense caps, as applicable, noting that any contractual fee waivers and expense caps had been approved by the Board. The Board also considered the extent to which the Master Portfolios and the Funds benefit from such economies in a variety of ways and whether there should be changes in the advisory fee rate or breakpoint structure in order to enable the Master Portfolios and the Funds to more fully participate in these economies of scale. The Board considered each Master Portfolio’s asset levels and whether the current fee schedule was appropriate. In their consideration, the Board Members took into account the existence of any expense caps and further considered the continuation and/or implementation, as applicable, of such caps.

E. Other Factors Deemed Relevant by the Board Members:The Board, including the Independent Board Members, also took into account other ancillary or“fall-out” benefits that BlackRock or its affiliates may derive from BlackRock’s respective relationships with the Master Portfolios and the Funds, both tangible and intangible, such as BlackRock’s ability to leverage its investment professionals who manage other portfolios and risk management personnel, an increase in BlackRock’s profile in the investment advisory community, and the engagement of BlackRock’s affiliates as service providers to the Master Portfolios and the Funds, including for administrative, distribution, securities lending and cash management services. The Board also considered BlackRock’s overall operations and its efforts to expand the scale of, and improve the quality of, its operations. The Board also noted that, subject to applicable law, BlackRock may use and benefit from third party research obtained by soft dollars generated by certain registered fund transactions to assist in managing all or a number of its other client accounts.

In connection with its consideration of the Agreement, the Board also received information regarding BlackRock’s brokerage and soft dollar practices. The Board received reports from BlackRock which included information on brokerage commissions and trade execution practices throughout the year.

The Board noted the competitive nature of theopen-end fund marketplace, and that shareholders are able to redeem their Fund shares if they believe that the pertinent Fund’s and/or Master Portfolio’s fees and expenses are too high or if they are dissatisfied with the performance of the Fund.

Conclusion

The Board of the Master LLC, including the Independent Board Members, unanimously approved the continuation of the Agreement between the Manager and the Master LLC, on behalf of each Master Portfolio, for aone-year term ending June 30, 2020. Based upon its evaluation of all of the aforementioned factors in their totality, as well as other information, the Board of the Master LLC, including the Independent Board Members, was satisfied that the terms of the Agreement were fair and reasonable and in the best interest of each Master Portfolio and its shareholders. The Board of the Corporation, including the Independent Board Members, also considered the continuation of the Agreement with respect to each Master Portfolio and found the Agreement to be satisfactory. In arriving at its decision to approve the Agreement, the Board of the Master LLC did not identify any single factor or group of factors asall-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination.

(e)(1) Audit CommitteePre-Approval Policies and Procedures:

Each Committee has adopted policies and procedures with regard to thepre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specificpre-approval by the registrant’s Committee. The Committee also must approve othernon-audit services provided to the registrant and thosenon-audit services provided to the Investment Adviser and Affiliated Service Providers that relate directly to the operations and the financial reporting of the registrant. Certain of thesenon-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 specificcase-by-case basis (“generalpre-approval”). The term of any generalpre-approval is 12 months from the date of thepre-approval, unless the Committee provides for a different period. Tax or othernon-audit services provided to the registrants which have a direct impact on the operations or financial reporting of the registrant will only be deemedpre-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 thepre-approved cost levels will require specificpre-approval by the registrant’s Committee, as will any other services not subject to generalpre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to generalpre-approval at the next regularly scheduledin-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 permittednon-audit services, including services exceedingpre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by either Committee pursuant to the de minimus exception in paragraph (c)(7)(i)(C) of Rule2-01 of RegulationS-X.
