Fund Description: iShares Global Green Bond ETF is an exchange-traded index fund or Index ETF which is a separate investment portfolio of the iShares Trust, an open-end investment management company. <p> INVESTMENT OBJECTIVE: iShares Global Green Bond ETF seeks to track the investment results of the Bloomberg Barclays MSCI Global Green Bond Select Index composed of global investment-grade green bonds that are issued to fund environmental projects, while mitigating exposure to currency fluctuations versus the U.S. dollar. <p> INDEX DESCRIPTION: The Bloomberg Barclays MSCI Green Bond Index offers investors an objective and robust measure of the global market for fixed income securities issued to fund projects with direct environmental benefits. An independent research-driven methodology is used to evaluate index-eligible green bonds to ensure they adhere to established Green Bond Principles and to classify bonds by their environmental use of proceeds. <p> FUND STRATEGY: The Fund seeks to track the investment results of the Bloomberg Barclays MSCI Global Green Bond Select Index which measures the performance of global investment-grade (as determined by Bloomberg Index Services Limited, a subsidiary of Bloomberg Barclays Capital, Inc.) green bonds issued to fund projects with direct environmental benefits. Green bonds are fixed income securities, the proceeds of which are exclusively and formally applied to projects or activities that promote climate or other environmental sustainability purposes. For inclusion in the Underlying Index, securities are independently evaluated by MSCI ESG Research LLC pursuant to an agreement between MSCI ESG Research and Bloomberg Index Services Limited (or an affiliate), based on four criteria specified in the Green Bond Principles published by MSCI ESG Research (“Green Bond Principles”). The first criterion for bond eligibility in the Underlying Index is an evaluation of whether the use of proceeds falls within at least one of six eligible environmental categories defined by MSCI ESG Research (i.e., alternative energy, energy efficiency, pollution prevention and control, sustainable water, green building, and climate adaption). The remaining three criteria for evaluation and inclusion in the Underlying Index are the existence of processes for green project evaluation and selection, the existence of processes for management of proceeds, and the existence of a commitment to ongoing reporting of the environmental impact. Both self-labeled green bonds and unlabeled bonds are evaluated using these criteria for potential inclusion in the Underlying Index. So long as projects fall within an eligible MSCI ESG Research green bond category and there is sufficient transparency on the use of proceeds, a bond is considered for the Underlying Index even if it is not explicitly marketed as a green bond. Meeting all four criteria is required for bonds issued after the publication of the Green Bond Principles in January 2014. Green bonds issued prior to 2014 that are widely accepted by investors as green bonds may still qualify for the Underlying Index, even if not all four principles are satisfied, since no formal guidelines were available to issuers at the time of issuance. The Underlying Index includes sovereign and government-related debt, corporate bonds and securitized bonds denominated in currencies determined by the Index Provider from both developed and emerging market issuers. As of October 31, 2020, the Underlying Index was comprised of securities issued by entities in the following 38 countries as well as securities issued or guaranteed by supranational entities: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Czech Republic, Denmark, Finland, France, Germany, Hong Kong, Hungary, India, Indonesia, Ireland, Italy, Japan, Lithuania, Luxembourg, Mexico, the Netherlands, Norway, the Philippines, Poland, Portugal, Romania, Russia, Saudi Arabia, Singapore, South Korea, Spain, Sweden, Switzerland, the United Arab Emirates, the U.K. and the U.S. As of October 31, 2020, a significant portion of the Underlying Index is represented by financials, sovereign and quasi-sovereign debt obligations and non-U.S. agency debt securities. <p> FUND MANAGEMENT: BlackRock Fund Advisors (BFA) serves as the investment adviser to the Fund.
