Report of Independent Public Accountants
To the Board of Trustees of Pioneer Bond Fund:
In planning and performing our audit of the financial statements of Pioneer Bond
Fund for the year ended June 30, 2000, 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 Pioneer Bond 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, 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
June 30, 2000.
This report is intended solely for the information and use of management, the
Board of Trustees of Pioneer Bond Fund, and the Securities and Exchange
Commission.
