7B Accountant's Report on Internal Control

                     Report of Independent Auditors


To the Shareholders and Board of Trustees of
Liberty Acorn Trust



In planning and performing our audit of the financial statements of Liberty
Acorn Fund, Liberty Acorn International, Liberty Acorn USA, Liberty Acorn
Twenty, Liberty Acorn Foreign Forty, and Columbia Thermostat Fund, comprising
the Liberty Acorn Trust, for the period ended December 31, 2002, we considered
its internal control, including control activities for safeguarding securities,
in order to determine our auditing procedures for the purpose of expressing our
opinion on the financial statements and to comply with the requirements of Form
N-SAR, not to provide assurance on internal control.

The management of the Liberty Acorn Trust is responsible for establishing and
maintaining internal control. In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected benefits and related
costs of controls. Generally, controls that are relevant to an audit pertain to
the entity's objective of preparing financial statements for external purposes
that are fairly presented in conformity with accounting principles generally
accepted in the United States. Those controls include the safeguarding of assets
against unauthorized acquisition, use, or disposition.

Because of inherent limitations in internal control, error or fraud may occur
and not be detected. Also, projection of any evaluation of internal control to
future periods is subject to the risk that it may become inadequate because of
changes in conditions or that the effectiveness of the design and operation may
deteriorate.

Our consideration of internal control would not necessarily disclose all matters
in internal control that might be material weaknesses under standards
established by the American Institute of Certified Public Accountants. A
material weakness is a condition in which the design or operation of one or more
of the internal control components does not reduce to a relatively low level the
risk that misstatements caused by error or fraud in amounts that would be
material in relation to the financial statements being audited may occur and not
be detected within a timely period by employees in the normal course of
performing their assigned functions. However, we noted no matters involving
internal control and its operation, including controls for safeguarding
securities, that we consider to be material weaknesses as defined above as of
December 31, 2002.

This report is intended solely for the information and use of management and the
Board of Trustees of the Liberty Acorn 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.

77Q3:

The Registrant's Chief Executive Officer and Chief Financial Officer, based on
their evaluation of the Registrant's disclosure controls and procedures as of
February 27, 2003, have concluded that such controls and procedures are
adequately designed to ensure that information required to be disclosed by the
Registrant in its reports that it files or submits under the Securities Exchange
Act of 1934, as amended, is accumulated and communicated to the Registrant's
management, including the Chief Executive Officer and Chief Financial Officer,
or persons performing similar functions, as appropriate to allow timely
decisions regarding required disclosure. There were no significant changes in
the Registrant's internal controls or in other factors that could significantly
affect these controls subsequent to the date of the most recent evaluation,
including any corrective actions with regard to significant deficiencies and
material weaknesses.
