The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when sold or redeemed, may be worth more or less than the original cost. Current performance may be lower or higher than the performance quoted. The performance information for periods prior to the inception date of the share class are based on the Fund’s Class K Shares, adjusted to reflect the fees and expenses applicable to such share class. See the fund prospectus for more details.

Ratings

Morningstar Rating

Overall iShares S&P 500 Index Fund received a Morningstar Rating of 4 stars for the 3-year period, 4 stars for the 5-year period and - stars for the 10-year period, rated against 1214, 1076 and 807 Large Blend Funds, respectively. Performance results represent past performance and are no guarantee of future results. The Morningstar RatingTM for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. Morningstar Ratings are for the share classes cited only; other classes may have different ratings.

Overall Morningstar Rating for iShares S&P 500 Index Fund, Service Class, as of Jan 31, 2019 rated against 1214 Large Blend Funds.

Important Information

Carefully consider the Funds' investment objectives, risk factors, and charges and expenses before investing. This and other information can be found in the Funds' prospectuses or, if available, the summary prospectuses which may be obtained by visiting the iShares Fund and BlackRock Fund prospectus pages. Read the prospectus carefully before investing.

The portfolio holdings information shown for iShares S&P 500 Index Fund (the “Fund”) on this site are the portfolio holdings of S&P 500 Index Master Portfolio (the “Master Portfolio”). The Fund is a “feeder” fund that invests all of its assets in the Master Portfolio, a mutual fund that has the same investment objectives and strategies as the Fund. All investments are made at the level of the Master Portfolio. The Fund’s investment results will correspond directly to the investment results of the Master Portfolio. Because the Master Portfolio may have other investors, the percentage of the Master Portfolio held by the Fund may change from time to time. As of November 30, 2018, the Fund held 95.95% of the Master Portfolio.

Stock values fluctuate in price so the value of your investment can go down depending on market conditions.

The fund may use derivatives to hedge its investments or to seek to enhance returns. Derivatives entail risks relating to liquidity, leverage and credit that may reduce returns and increase volatility.

‡Morningstar Analyst Rating^™is not a credit or risk rating. It is a subjective evaluation performed by Morningstar’s manager research group, which consists of various Morningstar, Inc. subsidiaries (“Manager Research Group”). In the United States, that subsidiary is Morningstar Research Services LLC, which is registered with and governed by the U.S. Securities and Exchange Commission. The Manager Research Group evaluates funds based on five key pillars, which are process, performance, people, parent, and price. The Manager Research Group uses this five pillar evaluation to determine how they believe funds are likely to perform relative to a benchmark, or in the case of exchange-traded funds and index mutual funds, a relevant peer group, over the long term on a risk-adjusted basis. They consider quantitative and qualitative factors in their research, and the weight of each pillar may vary. The Analyst Rating scale is Gold, Silver, Bronze, Neutral, and Negative. A Morningstar Analyst Rating of Gold, Silver, or Bronze reflects the Manager Research Group’s conviction in a fund’s prospects for outperformance. Analyst Ratings ultimately reflect the Manager Research Group’s overall assessment, are overseen by an Analyst Rating Committee, and are continuously monitored and reevaluated at least every 14 months. For more detailed information about Morningstar’s Analyst Rating, including its methodology, please go to global.morningstar.com/managerdisclosures/.

The Morningstar Analyst Rating (i) should not be used as the sole basis in evaluating a fund, (ii) involves unknown risks and uncertainties which may cause Analyst expectations not to occur or to differ significantly from what they expected, and (iii) should not be considered an offer or solicitation to buy or sell the fund.

Performance results reflect past performance and are no guarantee of future results. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. All returns assume reinvestment of all dividends. Performance information shown without sales charge would have been lower if the applicable sales charge had been included. Performance during periods of exceptional market conditions should not be expected to be repeated in a normal market environment. Current performance may be lower or higher than the performance data quoted.

Performance shown for certain share classes of certain funds is synthetic, pre-inception performance leveraging the performance of a different share class of the fund. When evaluating fund performance, it is important to note that it does not represent actual performance of such share class. All performance after inception of the share class is actual performance. For details regarding which funds and share classes leverage synthetic, pre-inception performance, please visit this page.

Investing involves risk, including possible loss of principal.

Fund details, holdings and characteristics are as of the date noted and subject to change.

Yields are based on income earned for the period cited and on the Fund's NAV at the end of the period.

Some BlackRock funds make distributions of ordinary income and capital gains at calendar year end. Those distributions temporarily cause extraordinarily high yields. There is no assurance that a fund will repeat that yield in the future. Subsequent monthly distributions that do not include ordinary income or capital gains in the form of dividends will likely be lower.
