ITEM 77D/77Q1(B) - POLICIES WITH RESPECT TO SECURITIES INVESTMENTS:

On September 22, 2011, a Form Type 497, accession number 0001193125-11-254242,
which included a supplement dated September 22, 2011 to the registration
statement of Columbia Funds Series Trust, on behalf of Columbia Masters
International Equity Portfolio, was filed with the SEC. This is hereby
incorporated by reference as part of the response to these Items 77D and 77Q1(b)
of Form N-SAR. The supplement disclosed, effective September 26, 2011, among
other things, the following revised strategy for the Fund:

Under normal circumstances, the Fund invests most of its assets in shares of
mutual funds (Underlying Funds) managed by Columbia Management Investment
Advisers, LLC, the Fund's investment adviser (the Adviser), or its affiliates
(Columbia Funds).

The Adviser invests in Underlying Funds so that at least 80% of its net assets
are invested indirectly through such Underlying Funds in equity securities
(including common stocks and preferred stocks). The Underlying Funds, in turn,
invest primarily in foreign equity securities of developed and emerging markets.

The Adviser will attempt to achieve the Fund's objective by investing directly
in funds with regional specializations or with differing market cap
concentrations within similar regions.

The Adviser can modify the list of Underlying Funds and percentage allocations,
at any time, including by adding Underlying Funds introduced after the date of
this prospectus. The initial list of Underlying Funds is as follows:

     -    Columbia Acorn International

     -    Columbia Emerging Markets Fund

     -    Columbia Pacific/Asia Fund

     -    Columbia European Equity Fund

The Fund may invest in Underlying Funds that invest in special situations such
as companies involved in initial public offerings, tender offers, mergers and
other corporate restructurings, and in companies involved in management changes
or companies developing new technologies.

The Fund may invest in derivatives for both hedging and nonhedging purposes,
including, for example, seeking to enhance returns or as a substitute for a
position in an underlying asset. The Fund may invest in derivatives to manage
the Fund's overall risk exposure.

The Fund may invest in forward foreign currency contracts with a gross notional
value up to 100% of the Fund's net assets. The Fund does not actually take
ownership of foreign currencies or sell actual foreign currencies. Rather,
through forward currency contracts, the Fund gains economic exposure comparable
to the exposure that it would have if it had bought or sold the currencies
directly.

In investing in forward contracts, the Adviser utilizes a quantitative,
proprietary model that uses various fundamental and technical factors, including
current and historical data, to rank the anticipated value of several developed
countries' currencies relative to the U.S. dollar. The Adviser will enter into
long forward currency contracts for a limited number of the currencies that rank
higher in the model, and the Fund will experience profits (losses) to the extent
the value of the currency appreciates (depreciates) relative to the U.S. dollar.
Conversely, the Adviser will enter into short forward currency contracts for a
limited number of the currencies that rank lower in the model, and the Fund will
experience profits (losses) to the extent the value of the currency depreciates
(appreciates) relative to the U.S. dollar. The Adviser runs the model regularly
and generally seeks to maintain long and short forward currency contracts under
this model-driven strategy with approximately equal gross notional values.

The Adviser also uses forward contracts to manage the Fund's overall currency
exposures. A forward contract is an agreement between two parties to buy or sell
an asset at a specified future time at a price agreed today.

The Adviser may sell investments to adjust the allocation of the Fund's assets;
if the Adviser believes that an investment is no longer a suitable investment,
or that other investments are more attractive; to meet redemption requests; or
for other reasons.

On July 29, 2011, a Form Type 485BPOS, accession number 0001193125-11-202673, an
amendment to the registration statement of the Trust (the "Amendment") was filed
with the SEC. These are hereby incorporated by reference as part of the response
to these Items 77D and 77Q1(b) of Form N-SAR. The Amendment disclosed, among
other things, changes to the principal strategies of the Columbia Masters
International Equity Portfolio.

EX-99.77E LEGAL

                                                                     Exhibit 77E

ITEM 77E - LEGAL PROCEEDINGS:

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc. was filed in the
United States District Court for the District of Arizona. The plaintiffs allege
that they are investors in several American Express Company mutual funds
(branded as Columbia) and they purport to bring the action derivatively on
behalf of those funds under the Investment Company Act of 1940. The plaintiffs
allege that fees allegedly paid to the defendants by the funds for investment
advisory and administrative services are excessive. The plaintiffs seek remedies
including restitution and rescission of investment advisory and distribution
agreements. The plaintiffs voluntarily agreed to transfer this case to the
United States District Court for the District of Minnesota (the District Court).
In response to defendants' motion to dismiss the complaint, the District Court
dismissed one of plaintiffs' four claims and granted plaintiffs limited
discovery. Defendants moved for summary judgment in April 2007. Summary judgment
was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a
notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit)
on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary
judgment and remanded to the District Court for further proceedings. On August
6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court (the
Supreme Court), asking the Supreme Court to stay the District Court proceedings
while the Supreme Court considers and rules in a case captioned Jones v. Harris
Associates, which involves issues of law similar to those presented in the
Gallus case. On March 30, 2010, the Supreme Court issued its ruling in Jones v.
Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth
Circuit's decision in the Gallus case and remanded the case to the Eighth
Circuit for further consideration in light of the Supreme Court's decision in
Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the
Gallus case to the District Court for further consideration in light of the
Supreme Court's decision in Jones v. Harris Associates. On December 9, 2010, the
District Court reinstated its July 9, 2007 summary judgment order in favor of
the defendants. On January 10, 2011, plaintiffs filed a notice of appeal with
the Eighth Circuit. In response to the plaintiffs' opening appellate brief filed
on March 18, 2011, the defendants filed a response brief on May 4, 2011 with the
Eighth Circuit. The plaintiffs filed a reply brief on May 26, 2011.

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.
