Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of Columbia Funds Series Trust I

In planning and performing our audit of the financial statements of Dividend
Income Fund, High Yield Municipal Fund, High Yield Opportunity Fund,
International Bond Fund, and Strategic Income Fund  (each a series of Columbia
Funds Series Trust I and hereafter referred to as the "Funds") as of and for
the period ended May 31, 2012, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), 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-SAR, 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 fund'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 fund'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 fund; (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 fund
are being made only in accordance with authorizations of management and
trustees of the fund; and (3)  provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use or disposition
of a fund'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 Fund'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
Public Company Accounting Oversight Board (United States).  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 May 31, 2012.



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

                                                                    EXHIBIT 77E

Columbia Funds Series Trust I (the "Trust") - Annual N-SAR report for the
period ending 5/31/12

Columbia Dividend Income Fund
Columbia High Yield Municipal Fund
-------------------------------------------------------------------------------

Item 77E - Legal Proceedings:

In December 2005, without admitting or denying the allegations, American
Express Financial Corporation (AEFC, which is now known as Ameriprise
Financial, Inc. (Ameriprise Financial)) entered into settlement agreements
with the Securities and Exchange Commission (SEC) and Minnesota Department of
Commerce (MDOC) related to market timing activities. As a result, AEFC was
censured and ordered to cease and desist from committing or causing any
violations of certain provisions of the Investment Advisers Act of 1940, the
Investment Company Act of 1940, and various Minnesota laws. AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to retain an independent distribution consultant to assist in
developing a plan for distribution of all disgorgement and civil penalties
ordered by the SEC in accordance with various undertakings detailed at
www.sec.gov/litigation/admin/ia-2451.pdf. Ameriprise Financial and its
affiliates have cooperated with the SEC and the MDOC in these legal
proceedings, and have made regular reports to the funds' Boards of Trustees.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings,
including routine litigation, class actions, and governmental actions,
concerning matters arising in connection with the conduct of their business
activities. Ameriprise Financial believes that the Funds are not currently the
subject of, and that neither Ameriprise Financial nor any of its affiliates
are the subject of, any pending legal, arbitration or regulatory proceedings
that are likely to have a material adverse effect on the Funds or the ability
of Ameriprise Financial or its affiliates to perform under their contracts
with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission on legal
and regulatory matters that relate to Ameriprise Financial and its affiliates.
Copies of these filings may be obtained by accessing the SEC website at
www.sec.gov.

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse
effect on the Funds or the ability of Ameriprise Financial or its affiliates
to perform under their contracts with the Funds, these proceedings are subject
to uncertainties and, as such, we are unable to estimate the possible loss or
range of loss that may result. An adverse outcome in one or more of these
proceedings could result in adverse judgments, settlements, fines, penalties
or other relief that could have a material adverse effect on the consolidated
financial condition or results of operations of Ameriprise Financial.
