REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Shareholders and Board of Trustees of
Oppenheimer Core Bond Fund:
In planning and performing our audit of the financial statements of Oppenheimer
Core Bond Fund (the "Fund") as of and for the year ended December 31, 2008, in
accordance with the standards of the Public Company Accounting Oversight Board
(United States), we considered the Fund's internal control over financial
reporting, including controls over safeguarding securities, as a basis for
designing our auditing procedures for the purpose of expressing our opinion on
the financial statements and to comply with the requirements of Form N-SAR, but
not for the purpose of expressing an opinion on the effectiveness of the Fund's
internal control over financial reporting. Accordingly, we express no such
opinion.
The management of the Fund is responsible for establishing and maintaining
effective internal control over financial reporting. In fulfilling this
responsibility, estimates and judgments by management are required to assess the
expected benefits and related costs of controls. A company's internal control
over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted
accounting principles. A company's internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of
records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of a company's assets
that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions or that the degree of compliance
with the policies or procedures may deteriorate.
A deficiency in internal control over financial reporting exists when the design
or operation of a control does not allow management or employees, in the normal
course of performing their assigned functions, to prevent or detect
misstatements on a timely basis. A material weakness is a deficiency, or a
combination of deficiencies, in internal control over financial reporting, such
that there is a reasonable possibility that a material misstatement of the
company's annual or interim financial statements will not be prevented or
detected on a timely basis.
Our consideration of the Fund's internal control over financial reporting was
for the limited purpose described in the first paragraph and would not
necessarily disclose all deficiencies in internal control that might be material
weaknesses under standards established by the Public Company Accounting
Oversight Board (United States). However, we noted no deficiencies in the Fund's
internal control over financial reporting and its operation, including controls
for safeguarding securities, that we consider to be a material weakness, as
defined above, as of December 31, 2008.
This report is intended solely for the information and use of management and the
Board of Trustees of the Fund and the Securities and Exchange Commission and is
not intended to be and should not be used by anyone other than these specified
parties.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for December 31, 2008. Net assets of
the Fund were unaffected by the reclassifications.

Dear Sirs/Madams:

Exhibit to Form N-SAR

At a meeting held on August 20, 2008, the Board of Trustees of Oppenheimer Core
Bond Fund (the "Fund") appointed KPMG LLP as the independent registered public
accounting firm to the Fund for the 2009 fiscal year to replace the firm of
Deloitte & Touche LLP.

The reports of Deloitte & Touche LLP on the Fund's financial statements for the
fiscal years ended December 31, 2007 and December 31, 2008 contained no adverse
opinion or disclaimer of opinion and were not qualified or modified as to
uncertainty, audit scope or accounting principles.

During the Fund's fiscal years ended December 31, 2007 and December 31, 2008,
there were no disagreements between the Fund and Deloitte & Touche LLP on any
matter of accounting principles or practices, financial statement disclosure, or
auditing scope or procedures which, if not resolved to the satisfaction of
Deloitte & Touche LLP, would have caused Deloitte & Touche LLP to make reference
thereto in its report nor were there any "reportable events" as that term is
described in Item 304 (a)(1)(v) of Regulation S-K.


The Fund requested that Deloitte & Touche LLP furnish it with a letter addressed
to the Securities and Exchange Commission stating whether or not it agrees with
the above statements. A copy of such letter, dated February 27, 2009 is filed as
an exhibit to this Form N-SAR.
