To the Board of Trustees of
Pioneer Pioneer International Growth Fund:
In planning and performing our audit of the financial statements of Pioneer
International Growth Fund for the year ended November 30, 1997, we considered
its internal control structure, including controls over 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 Pioneer International Growth Fund 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
generally accepted accounting principles. Those controls include the
safeguarding of assets against unauthorized acquisition, use, or disposition.
Because of inherent limitations in internal control, errors or irregularities
may occur and may 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 any
specific internal control component does not reduce to a relatively low level
the risk that errors or irregularities 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,
including controls over safeguarding securities, that we consider to be material
weaknesses as defined above as of November 30, 1997.
This report is intended solely for the information and use of management and the
Securities and Exchange Commission.
