Sustainability Characteristics

Sustainability Characteristics

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. MSCI Ratings are currently unavailable for this fund.

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 0.00% and for Oil Sands 0.00%.

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.

Detailed Holdings and Analytics contains detailed portfolio holdings information and select analytics.



The values shown for “market value,” “weight,” and “notional value” (the “calculated values”) are based off of a price provided by a third-party pricing vendor for the portfolio holding and do not reflect the impact of systematic fair valuation (“the vendor price”). The vendor price is not necessarily the price at which the Fund values the portfolio holding for the purposes of determining its net asset value (the “valuation price”). Holdings data shown reflects the investment book of record, which may differ from the accounting book of record used for the purposes of determining the Net Assets of the Fund. Additionally, where applicable, foreign currency exchange rates with respect to the portfolio holdings denominated in non-U.S. currencies for the valuation price will be generally determined as of the close of business on the New York Stock Exchange, whereas for the vendor price will be generally determined as of 4 p.m. London. The calculated values may have been different if the valuation price were to have been used to calculate such values. The vendor price is as of the most recent date for which a price is available and may not necessarily be as of the date shown above.

Please see the “Determination of Net Asset Value” section of each Fund’s prospectus for additional information on the Fund’s valuation policies and procedures.

Type Fund
The maturity breakdown above is based on Weighted Average Life (WAL). WAL is the average length of time to the repayment of principal for the securities in the fund. This metric considers the likelihood that bonds will be called or prepaid before the scheduled maturity date.

as of 06/Dec/2024

% of Market Value

Type Fund
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.
Allocations are subject to change.
