To the Board of Trustees and Shareholders of
Berger/BIAM Worldwide Funds Trust
In planning and performing our audits of the financial statements
of Berger/BIAM Worldwide Funds Trust for the year ended September
30, 1999, 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 Berger/BIAM Worldwide Funds 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 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
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 A
merican 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 September 30, 1999.
This report is intended solely for the information and use
of management and the Board of Trustees of Berger/BIAM
Worldwide Funds 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.
