Key Facts About BlackRock Large Cap Value Retirement Portfolio

Investment Objective

The investment objective of BlackRock Large Cap Value Retirement Portfolio (“Retirement Value Fund” or the “Fund”), a series of BlackRock Large Cap Series Funds, Inc. (the “Corporation”), is to seek long-term capital growth. In other words, the Fund tries to choose investments that will increase in value.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold Class K Shares of Retirement Value Fund.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) ¹				Class K Shares
Management Fee ¹				0.50%
Distribution and/or Service (12b-1) Fees				None
Other Expenses				0.18%
Total Annual Fund Operating Expenses				0.68%
Fee Waivers and/or Expense Reimbursements ²				(0.01)%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements ²				0.67%

The fees and expenses shown in the table and the example that follows include both the expenses of Retirement Value Fund and Retirement Value Fund’s share of the allocated expenses of Master Large Cap Value Portfolio (“Master Value Portfolio” or the “Portfolio”), a series of Master Large Cap Series LLC. Management Fees are paid by Master Value Portfolio.

As described in the “Management of the Funds” section of the Fund’s prospectus on pages 27-31, BlackRock Advisors, LLC (“BlackRock”) has contractually agreed to waive and/or reimburse fees and/or expenses with respect to Retirement Value Fund in order to limit Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements (excluding Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses) to 0.67% of average daily net assets until February 1, 2015. The agreement may be terminated upon 90 days’ notice by a majority of the non-interested directors of the Corporation or by a vote of a majority of the outstanding voting securities of the Fund.

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

				1 Year				3 Years				5 Years				10 Years
Class K Shares				$	68			$	217			$	378			$	846

Portfolio Turnover:

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 40% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Retirement Value Fund seeks to achieve its objective by investing at least 80% of its assets in equity securities, primarily common stock, of large cap companies located in the United States that BlackRock selects from among those that are, at the time of purchase, included in the Fund’s benchmark, the Russell ^® 1000 Value Index. Equity securities consist primarily of common stock, preferred stock, securities convertible into common stock and securities or other instruments whose price is linked to the value of common stock. Large cap companies are companies that at the time of purchase have a market capitalization equal to or greater than the top 80% of the companies that comprise the Russell 1000 ^® Index. As of June 28, 2013, the most recent rebalance date, the lowest market capitalization in this group was $3.8 billion. The market capitalizations of companies in the index change with market conditions and the composition of the index.

The Fund is a “feeder” fund that invests all of its assets in Master Value Portfolio, which has the same investment objective and strategies as the Fund. All investments are made at the Portfolio level. This structure is sometimes called a “master/feeder” structure. The Fund’s investment results will correspond directly to the investment results of the Portfolio. For simplicity, the prospectus uses the terms “Retirement Value Fund” or “Fund” (as applicable) to include the Portfolio.

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in Retirement Value Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks of investing in the Fund.

Equity Securities Risk — Stock markets are volatile. The price of an equity security fluctuates based on changes in a company’s financial condition and overall market and economic conditions.

Investment Style Risk — Under certain market conditions, value investments have performed better during periods of economic recovery. Therefore, this investment style may over time go in and out of favor. At times when the investment style used by the Fund is out of favor, the Fund may underperform other equity funds that use different investment styles.

Market Risk and Selection Risk — Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.

Payments to Broker/Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary, the Fund and BlackRock Investments, LLC, the Fund’s distributor, or its affiliates may pay the intermediary for the sale of Fund shares and related services.
