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 October 31, 2019, 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 October 31, 2019.

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.

LEGAL PROCEEDINGS

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

On June 16, 2016, Garth Jensen, Philip
Steele, Seth Hardy, Ray Moylan, Kenneth
Powaga, Cynthia Powaga, Roger Foster and
Robert Kachelek (the "Plaintiffs"), 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 U.S.
Preferred and Income Securities ETF) filed a
putative 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"). 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. The
plaintiffs' complaint was dismissed in
December 2016 and on January 6, 2017,
plaintiffs filed an amended complaint. On April
27, 2017, the court partially granted the
defendants' motion for judgment on the
pleadings, dismissing certain of the plaintiffs'
claims. 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. On December
1, 2017, the Plaintiffs appealed the Court's
decision. The appeal was fully briefed on
January 18, 2019, and a hearing on Plaintiffs'
appeal has been scheduled for October 22,
2019.
