To the Shareholders and Board of Directors
of BT Advisor Funds:
In planning and performing our audit of the financial statements and financial
highlights of EAFE Equity Index Fund, Small Cap Index Fund, and US Bond Index
Fund (three of the Funds comprising the BT Advisor Funds, hereafter referred to
as the "Funds") for the year ended December 31, 1998, 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 financial highlights and to comply with the
requirements of Form N-SAR, not to provide assurance on internal control.
The management of the Funds 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 and financial highlights
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, 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 and financial highlights 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 over
safeguarding securities, that we consider to be material weaknesses as defined
above as of December 31, 1998.
This report is intended solely for the information and use of management, the
Board of Directors of the BT Advisor Funds and the Securities and Exchange
Commission.
