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 Trust. The tax
character of distributions paid during the years ended June 30, 2008 and June
30, 2007 was as follows:

                                                Year Ended        Year Ended

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Shareholders and Board of Trustees of
Centennial California Tax Exempt Trust:
In planning and performing our audit of the financial statements of Centennial
California Tax Exempt Trust (the "Trust") as of and for the year ended June 30,
2008, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), we considered the Trust'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
Trust's internal control over financial reporting. Accordingly, we express no
such opinion.
The management of the Trust 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 Trust'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
Trust'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 June 30, 2008.
This report is intended solely for the information and use of management and the
Board of Trustees of the 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.
