Sustainability Characteristics

Sustainability Characteristics

Sustainability Characteristics provide investors with specific non-traditional metrics. Alongside other metrics and information, these enable investors to evaluate funds on certain environmental, social and governance characteristics. Sustainability Characteristics do not provide an indication of current or future performance nor do they represent the potential risk and reward profile of a fund. They are provided for transparency and for information purposes only. Sustainability Characteristics should not be considered solely or in isolation, but instead are one type of information that investors may wish to consider when assessing a fund. Learn more


This fund does not seek to follow a sustainable, impact or ESG investment strategy. The metrics do not change the fund’s investment objective or constrain the fund’s investable universe, and there is no indication that a sustainable, impact or ESG investment strategy will be adopted by the fund. For more information regarding the fund's investment strategy, please see the fund's prospectus.

All data is from MSCI ESG Fund Ratings as of Nov 21, 2024, based on holdings as of Apr 30, 2024. As such, the fund’s sustainable characteristics may differ from MSCI ESG Fund Ratings from time to time.

To be included in MSCI ESG Fund Ratings, 65% (or 50% for bond funds and money market funds) of the fund’s gross weight must come from securities with ESG coverage by MSCI ESG Research (certain cash positions and other asset types deemed not relevant for ESG analysis by MSCI are removed prior to calculating a fund’s gross weight; the absolute values of short positions are included but treated as uncovered), the fund’s holdings date must be less than one year old, and the fund must have at least ten securities.

Business Involvement

Business Involvement

Business Involvement metrics can help investors gain a more comprehensive view of specific activities in which a fund may be exposed through its investments.


Business Involvement metrics are not indicative of a fund’s investment objective, and, unless otherwise stated in fund documentation and included within a fund’s investment objective, do not change a fund’s investment objective or constrain the fund’s investable universe. For more information regarding a fund's investment strategy, please see the fund's prospectus.

BlackRock business involvement exposures as shown above for Thermal Coal and Oil Sands are calculated and reported for companies that generate more than 5% of revenue from thermal coal or oil sands as defined by MSCI ESG Research. For the exposure to companies that generate any revenue from thermal coal or oil sands (at a 0% revenue threshold), as defined by MSCI ESG Research, it is as follows: Thermal Coal 0.04% and for Oil Sands 0.34%.

Business Involvement metrics are calculated by BlackRock using data from MSCI ESG Research which provides a profile of each company’s specific business involvement. BlackRock leverages this data to provide a summed up view across holdings and translates it to a fund's market value exposure to the listed Business Involvement areas above.


Business Involvement metrics are designed only to identify companies where MSCI has conducted research and identified as having involvement in the covered activity. As a result, it is possible there is additional involvement in these covered activities where MSCI does not have coverage. This information should not be used to produce comprehensive lists of companies without involvement. Business Involvement metrics are only displayed if at least 1% of the fund’s gross weight includes securities covered by MSCI ESG Research.

The fund itself has not been rated by an independent rating agency. Credit quality ratings on underlying securities of the fund are received from S&P, Moody’s and Fitch and converted to the equivalent S&P major rating category. This breakdown is provided by BlackRock and takes the median rating of the three agencies when all three agencies rate a security the lower of the two ratings if only two agencies rate a security and one rating if that is all that is provided. Unrated securities do not necessarily indicate low quality. Below investment-grade is represented by a rating of BB and below. Ratings and portfolio credit quality may change over time.

Negative weightings may result from specific circumstances (including timing differences between trade and settle dates of securities purchased by the funds) and/or the use of certain financial instruments, including derivatives, which may be used to gain or reduce market exposure and/or risk management. Certain transactions the funds may utilize may give rise to a form of leverage through either (a) additional market exposure or (b) borrowing capital in an attempt to increase investment return. The use of such transactions includes certain leverage-related risks, including potential for higher volatility, greater decline of the fund’s net asset value and fluctuations of dividends and distributions paid by the fund.

Allocations are subject to change.
