Report of Independent Registered
Public Accounting Firm

To the Board of Trustees of The Marsico
Investment Fund and Shareholders of
Marsico Focus Fund, Marsico Growth
Fund, Marsico Midcap Growth Focus
Fund, Marsico International
Opportunities Fund and Marsico Global
Fund

In planning and performing our audits
of the financial statements of Marsico
Focus Fund, Marsico Growth Fund,
Marsico Midcap Growth Focus Fund,
Marsico International Opportunities
Fund and Marsico Global Fund
(constituting The Marsico Investment
Fund, hereafter collectively referred to
as the "Funds") as of and for the year
ended September 30, 2023, 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 their operations,
including controls over safeguarding
securities, that we consider to be
material weaknesses as defined above as
of September 30, 2023.

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