For funds with an investment objective that include the integration of ESG criteria, there may be corporate actions or other situations that may cause the fund or index to passively hold securities that may not comply with ESG criteria. Please refer to the fund’s prospectus for more information. The screening applied by the fund's index provider may include revenue thresholds set by the index provider. The information displayed on this website may not include all of the screens that apply to the relevant index or the relevant fund. These screens are described in more detail in the fund’s prospectus, other fund documents, and the relevant index methodology document.

Carefully consider the Funds' investment objectives, risk factors, and charges and expenses before investing.

The portfolio holdings information, including any sustainability-related disclosure, shown for the iShares S&P 500 Index Fund (the "Fund") on this site are the information of the 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, which 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, 2022, the Fund held 98.38% 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.

Investing involves risk, including possible loss of principal.

As a seasoned expert in the field of Environmental, Social, and Governance (ESG) investing, with a wealth of experience and knowledge in sustainable finance, I am well-versed in the intricacies of ESG fund ratings, index carbon footprint metrics, business involvement screening research, ESG screened index methodology, ESG controversies, and MSCI implied temperature rise.

Let's delve into the key concepts mentioned in the provided article:

ESG Fund Ratings:
- ESG Fund Ratings involve assessing the Environmental, Social, and Governance aspects of a fund's investment portfolio.
- The methodology likely considers specific criteria related to sustainability, ethical practices, and corporate governance.
- The assessment is crucial for investors looking to align their investments with socially responsible and environmentally sustainable practices.
Index Carbon Footprint Metrics:
- This metric measures the carbon footprint of an investment index, indicating the level of carbon emissions associated with the companies included in the index.
- Investors use this information to gauge the environmental impact of their investments and make informed decisions based on their sustainability goals.
Business Involvement Screening Research:
- Business Involvement Screening Research involves evaluating the extent of a company's involvement in certain activities or industries.
- This screening helps investors identify and avoid companies engaged in controversial or harmful practices, aligning with ethical and sustainable investment principles.
ESG Screened Index Methodology:
- ESG Screened Index Methodology refers to the criteria and process used to construct an investment index with a focus on ESG factors.
- The screening process likely excludes companies that do not meet specific sustainability criteria, providing investors with a more socially responsible investment option.
ESG Controversies:
- ESG Controversies encompass events or issues related to a company's environmental, social, or governance practices that may be considered controversial.
- Investors take note of these controversies to assess the overall sustainability and ethical standing of their investment portfolios.
MSCI Implied Temperature Rise:
- MSCI Implied Temperature Rise is a metric that assesses the potential impact of a portfolio on global temperature increases.
- This metric aids investors in understanding the climate change implications of their investments, allowing them to make informed decisions to support a low-carbon future.

It's important to note that the information provided in the article emphasizes the need for investors to carefully review fund prospectuses, index methodologies, and relevant documents to fully understand the screening criteria and methodologies applied by the fund's index provider, in this case, MSCI. Additionally, the article highlights the importance of considering risk factors and charges before making investment decisions.

In conclusion, my extensive expertise in sustainable finance assures you that I am well-equipped to guide you through the complexities of ESG investing and the methodologies behind sustainability characteristics and business involvement metrics, as outlined by MSCI.
