Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover ratemay 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 Fund’s performance.

Principal Investment Strategies of the Fund

The Fund seeks to track the investment results of the Russell Midcap® Index (the“Underlying Index”), which measures the performance of the mid-capitalization sector of the U.S. equity market. The Underlying Index is a float-adjusted, capitalization-weighted index of the 800 smallest issuers in the Russell 1000® Index. The Underlying Index includes equity securities issued by issuers which range in size between approximately $3 billionand $23 billion, although this range may change from time to time. As of December 31, 2014, the Underlying Index represented approximately 27.2% of the total market capitalization of all publicly-traded U.S. equity securities. Componentsprimarily include financial services, consumer discretionary and healthcare companies, and may change over time.

BlackRock uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities thatcollectively has an investment

profile similar to that of the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization andindustry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets, plus the amount of anyborrowing for investment purposes, in securities of the Underlying Index.

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in the Fund, as wellas 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. Thefollowing is a summary description of principal risks of investing in the Fund.

n

Asset Class Risk — Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securitiesmarkets, a particular securities market or other asset classes.

n

Concentration Risk — The Fund reserves the right to concentrate its investments (i.e., invest 25% or more of its total assets insecurities of issuers in a particular industry) to approximately the same extent that the Underlying Index concentrates in a particular industry. To the extent the Fund concentrates in a particular industry, it may be more susceptible to economicconditions and risks affecting that industry.

n

Consumer Discretionary Sector Risk — The consumer discretionary sector may be affected by changes in domestic and international economies,exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.

n

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

n

Financials Sector Risk — Performance of companies in the financials sector may be adversely impacted by many factors, including, among others,government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capitalrequirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

n

Healthcare Sector Risk — The healthcare sector may be affected by government regulations and government healthcare programs, increases ordecreases in the cost of medical products and services and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect thatcompany’s profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

n

Index Fund Risk — An index fund has operating and other expenses while an index does not. As a result, while the Fund will attempt to trackthe Underlying Index as closely as possible, it will tend to underperform the Underlying Index to some degree over time.

n

Index-Related Risk — There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and thereforeachieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data mayoccur from time to time and may not be identified and corrected for a period of time, and may have an adverse impact on the Fund and its shareholders.

n

Issuer Risk — Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes in the financialcondition or credit rating of an issuer of those securities may cause the value of the securities to decline.

n

Management Risk — As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BlackRock’s investmentstrategy may not produce the intended results.

n

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, includingthe 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 withsimilar investment objectives and investment strategies. This means you may lose money.

n

Mid Cap Securities Risk — The securities of mid cap companies generally trade in lower volumes and are generally subject to greater and lesspredictable price changes than the securities of larger capitalization companies.
