In planning and performing our audits of the financial 
statements of the funds listed in Appendix A, (hereafter 
referred to as the "Funds") as of and for the periods 
ended February 28, 2021, in accordance with the 
standards of the Public Company Accounting Oversight 
Board (United States) (PCAOB), we considered the 
Funds' internal control over financial reporting, 
including controls over safeguarding securities, as a basis 
for designing our auditing procedures for the purpose of 
expressing our opinion on the financial statements and to 
comply with the requirements of Form N-CEN, but not 
for the purpose of expressing an opinion on the 
effectiveness of the Funds' internal control over financial 
reporting.  Accordingly, we do not express an opinion on 
the effectiveness of the Funds' internal control over 
financial reporting.

The management of the Funds is responsible for 
establishing and maintaining effective internal control 
over financial reporting.  In fulfilling this responsibility, 
estimates and judgments by management are required to 
assess the expected benefits and related costs of controls.  
A company's internal control over financial reporting is a 
process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the 
preparation of financial statements for external purposes 
in accordance with generally accepted accounting 
principles.  A company's internal control over financial 
reporting includes those policies and procedures that (1) 
pertain to the maintenance of records that, in reasonable 
detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide 
reasonable assurance that transactions are recorded as 
necessary to permit preparation of financial statements 
in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the 
company are being made only in accordance with 
authorizations of management and directors of the 
company; and (3) provide reasonable assurance 
regarding prevention or timely detection of unauthorized 
acquisition, use or disposition of a company's assets that 
could have a material effect on the financial statements.

Because of its inherent limitations, internal control over 
financial reporting may not prevent or detect 
misstatements.  Also, projections of any evaluation of 
effectiveness to future periods are subject to the risk that 
controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the 
policies or procedures may deteriorate.

A deficiency in internal control over financial reporting 
exists when the design or operation of a control does not 
allow management or employees, in the normal course of 
performing their assigned functions, to prevent or detect 
misstatements on a timely basis.  A material weakness is 
a deficiency, or a combination of deficiencies, in internal 
control over financial reporting, such that there is a 
reasonable possibility that a material misstatement of the 
company's annual or interim financial statements will 
not be prevented or detected on a timely basis.  

Our consideration of the Funds' internal control over 
financial reporting was for the limited purpose described 
in the first paragraph and would not necessarily disclose 
all deficiencies in internal control over financial reporting 
that might be material weaknesses under standards 
established by the PCAOB.  However, we noted no 
deficiencies in the Funds' internal control over financial 
reporting and its operation, including controls over 
safeguarding securities, that we consider to be material 
weaknesses as defined above as of February 28, 2021.

This report is intended solely for the information and use 
of the Board of Trustees of iShares Trust and the 
Securities and Exchange Commission and is not intended 
to be and should not be used by anyone other than these 
specified parties.

In re: Jensen, et al., v. iShares Trust, et al., 
CGC 16-552567

On June 16, 2016, investors in certain iShares 
funds (iShares Core S&P Small-Cap ETF, 
iShares Russell 1000 Growth ETF, iShares Core 
S&P 500 ETF, iShares Russell Mid-Cap Growth 
ETF, iShares Russell Mid-Cap ETF, iShares 
Russell Mid-Cap Value ETF, iShares Select 
Dividend ETF, iShares Morningstar Mid-Cap 
ETF, iShares Morningstar Large-Cap ETF, 
iShares U.S. Aerospace & Defense ETF and 
iShares Preferred and Income Securities ETF) 
filed a class action lawsuit against iShares Trust, 
BlackRock, Inc. and certain of its advisory 
affiliates, and certain directors/trustees and 
officers of the Funds (collectively, "Defendants") 
in California State Court. The lawsuit alleges the 
Defendants violated federal securities laws by 
failing to adequately disclose in the 
prospectuses issued by the funds noted above 
the risks of using stop-loss orders in the event of 
a 'flash crash', such as the one that occurred on 
May 6, 2010. On September 18, 2017, the court 
issued a Statement of Decision holding that the 
Plaintiffs lack standing to assert their claims. On 
October 11, 2017, the court entered final 
judgment dismissing all of the Plaintiffs' claims 
with prejudice.  In an opinion dated January 23, 
2020, the California Court of Appeal affirmed the 
dismissal of Plaintiffs' claims. On March 3, 2020, 
plaintiffs filed a petition for review by the 
California Supreme Court.  On May 27, 2020, 
the California Supreme Court denied Plaintiff's 
petition for review. The case is now closed.
