NOTES

AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO
PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN THE FUND.

THE FUND'S INVESTMENT STRATEGY, ALLOCATIONS, AND FOCUS CAN CHANGE OVER TIME. THE
MENTION OF SPECIFIC FUND HOLDINGS DOES NOT CONSTITUTE A RECOMMENDATION BY

INVESTORS SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, AND CHARGES
AND EXPENSES CAREFULLY BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS THIS AND
OTHER INFORMATION ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR FINANCIAL

FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include contingent deferred sales charges on
redemptions; and redemption fees, if any; and (2) ongoing costs, including
management fees and other Fund expenses. These examples are intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended July 31, 2007.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you paid for the
period. You may use this information to compare the ongoing costs of investing
in the Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold with the 5% hypothetical examples that appear in
the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
contingent deferred sales charges (loads), or a $12.00 fee imposed annually on
accounts valued at less than $500.00 (subject to exceptions described in the
Statement of Additional Information). Therefore, the "hypothetical" lines of

the table are useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

Class N Hypothetical         1,000.00        1,018.84        6.02

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 181/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended July 31, 2007 are as follows:

CLASS        EXPENSE RATIOS
- ---------------------------
Class A           0.95%
- ---------------------------
Class B           1.19
- ---------------------------
Class C           1.27
- ---------------------------
Class N           1.20

The expense ratios reflect reduction to custodian expenses and voluntary waivers
or reimbursements by the Fund's Manager and Distributor that can be terminated
at any time, without advance notice. The "Financial Highlights" tables in the
Fund's financial statements, included in this report, also show the gross
expense ratios, without such waivers or reimbursements and reduction to
custodian expenses, if applicable.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Cash Reserves (the Fund) is registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company. The
Fund's investment objective is to seek the maximum current income that is
consistent with stability of principal. The Fund's investment advisor is
OppenheimerFunds, Inc. (the Manager).

      The Fund offers Class A, Class B, Class C and Class N shares. Class A
shares are sold at their offering price, which is the net asset value per share
without any initial sales charge. Class B, Class C and Class N shares are sold
without a front-end sales charge but may be subject to a contingent deferred
sales charge (CDSC). Class N shares are sold only through retirement plans.
Retirement plans that offer Class N shares may impose charges on those accounts.
All classes of shares have identical rights and voting privileges with respect
to the Fund in general and exclusive voting rights on matters that affect that
class alone. Earnings, net assets and net asset value per share may differ due
to each class having its own expenses, such as transfer and shareholder
servicing agent fees and shareholder communications, directly attributable to
that class. Class A, B, C and N have separate distribution and/or service plans.
Class B shares will automatically convert to Class A shares six years after the
date of purchase.

      The following is a summary of significant accounting policies consistently
followed by the Fund.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. As permitted under Rule 2a-7 of the Investment Company Act
of 1940, portfolio securities are valued on the basis of amortized cost, which
approximates market value. If amortized cost is determined not to approximate
market value, the fair value of the portfolio securities will be determined
under procedures approved by the Fund's Board of Trustees.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis or
forward commitment take place generally at least ten days or more after the
trade date. Normally the settlement date occurs within six months after the
trade date; however, the Fund may, from time to time, purchase securities whose
settlement date extends six months or more beyond trade date. During this
period, such securities do not earn interest, are subject to market fluctuation
and may increase or decrease in value prior to their delivery. The Fund
maintains internally designated assets with a market value equal to or greater
than the amount of its purchase commitments. The purchase of securities on a
when-issued basis or forward commitment may increase the volatility of the
Fund's net asset value to the extent the Fund executes such transactions while
remaining substantially fully invested. The Fund may also sell securities that
it purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase. As of July 31, 2007, the Fund had purchased $20,994,800
of securities issued on a when-issued basis or forward commitment.

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Fund intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income to shareholders,
therefore, no federal income or excise tax provision is required.

The tax components of capital shown in the following table represent
distribution requirements the Fund must satisfy under the income tax
regulations, losses the Fund may be able to offset against income and gains
realized in future years for federal income tax purposes.

            UNDISTRIBUTED NET     UNDISTRIBUTED     ACCUMULATED LOSS
            INVESTMENT INCOME    LONG-TERM GAIN   CARRYFORWARD 1,2,3

            $1,015,540                      $--                 $328

1. As of July 31, 2007, the Fund had $328 of net capital loss carryforwards
available to offset future realized capital gains, if any, and thereby reduce
future taxable gain distributions. As of July 31, 2007, details of the capital
loss carryforwards were as follows:

            EXPIRING
            -------------------
            2015           $328

2. During the fiscal year ended July 31, 2007, the Fund did not utilize any
capital loss carryforward.

3. During the fiscal year ended July 31, 2006, the Fund did not utilize any
capital loss carryforward.

The tax character of distributions paid during the years ended July 31, 2007 and
July 31, 2006 was as follows:

                                          YEAR ENDED      YEAR ENDED
                                       JULY 31, 2007   JULY 31, 2006
            --------------------------------------------------------
            Distributions paid from:
            Ordinary income              $40,067,289   $  29,423,428

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a compensation
deferral plan for independent trustees that enables trustees to elect to defer
receipt of all or a portion of the annual compensation they are entitled to
receive from the Fund. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are treated as though equal dollar
amounts had been invested in shares of the Fund or in other Oppenheimer funds
selected by the Trustee. The Fund purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Fund asset equal to the deferred compensation liability. Such
assets are included as a component of "Other" within the asset section of the
Statement of Assets and Liabilities. Deferral of trustees' fees under the plan
will not affect the net assets of the Fund, and will not materially affect the
Fund's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the compensation deferral plan.


                         24 | OPPENHEIMER CASH RESERVES



- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income distributions, if any, are declared
daily and paid monthly. Capital gain distributions, if any, are declared and
paid annually but may be paid at other times to maintain the net asset value per
share at $1.00.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Fund on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Fund, at a rate equal to the
Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item,
if applicable, represents earnings on cash balances maintained by the Fund
during the period. Such interest expense and other custodian fees may be paid
with these earnings.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
INDEMNIFICATIONS. The Fund's organizational documents provide current and former
trustees and officers with a limited indemnification against liabilities arising
in connection with the performance of their duties to the Fund. In the normal
course of business, the Fund may also enter into contracts that provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown as this would be dependent on future claims that may be made against the
Fund. The risk of material loss from such claims is considered remote.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

- --------------------------------------------------------------------------------
2. SHARES OF BENEFICIAL INTEREST

The Fund has authorized an unlimited number of $0.001 par value shares of
beneficial interest of each class. Transactions in shares of beneficial interest

TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the Manager,
acts as the transfer and shareholder servicing agent for the Fund. The Fund pays
OFS a per account fee. For the year ended July 31, 2007, the Fund paid
$2,828,832 to OFS for services to the Fund.

- --------------------------------------------------------------------------------

Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor)
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.


                         26 | OPPENHEIMER CASH RESERVES



- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan for Class A
shares. It reimburses the Distributor for a portion of its costs incurred for
services provided to accounts that hold Class A shares. Reimbursement is made
periodically at an annual rate of up to 0.20% of the average annual net assets
of Class A shares of the Fund. The Distributor currently uses all of those fees
to pay dealers, brokers, banks and other financial institutions periodically for
providing personal services and maintenance of accounts of their customers that
hold Class A shares. Any unreimbursed expenses the Distributor incurs with
respect to Class A shares in any fiscal year cannot be recovered in subsequent
periods. Fees incurred by the Fund under the Plan are detailed in the Statement
of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans for Class B, Class C and Class N
shares to compensate the Distributor for its services in connection with the
distribution of these shares and servicing accounts. Under the plans, the Fund
pays the Distributor an annual asset-based sales charge of 0.75% on Class B
shares and Class C shares and for Class N shares, the Fund pays the Distributor
an annual service fee of 0.25% and an annual asset-based sales charge of 0.25%.
Effective January 1, 2003, the Fund decreased the asset-based sales charge on
Class B and Class C shares to 0.50% of average daily net assets per annum. The
Distributor is entitled to receive a service fee of 0.25% per year under each
plan, but the Board of Trustees has not authorized the Fund to pay the service
fees on Class B and Class C shares at this time. If either the Class B, Class C
or Class N plan is terminated by the Fund or by the shareholders of a class, the
Board of Trustees and its independent trustees must determine whether the
Distributor shall be entitled to payment from the Fund of all or a portion of
the service fee and/or asset-based sales charge in respect to shares sold prior
to the effective date of such termination. The Distributor determines its
uncompensated expenses under the plan at calendar quarter ends. The
Distributor's aggregate uncompensated expenses under the plan at June 30, 2007
Class N shares were $7,311,886. Fees incurred by the Fund under the plans are
detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Contingent deferred sales charges (CDSC) do not represent an
expense of the Fund. They are deducted from the proceeds of redemptions of Fund
shares prior to remittance. The CDSC retained by the Distributor on the
redemption of shares is shown in the following table for the period indicated.

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

WAIVERS AND REIMBURSEMENTS OF EXPENSES. Effective December 6, 2002, the Manager
has agreed to limit the Fund's management fee to 0.40% of the Fund's average net
assets for each class of shares. As a result of this limitation the Fund was
reimbursed $607,826 for the year ended July 31, 2007. This expense limitation
can be amended or terminated at any time without advance notice.

      OppenheimerFunds Distributor, Inc. (OFDI) has voluntarily agreed to reduce
Class B and Class C Distribution and/or Service (12b-1) Fees it is entitled to
receive by 0.25% of the average annual net assets for each respective class of
shares. During the year ended July 31, 2007, OFDI waived $280,419 and $378,987
for Class B and Class C shares, respectively. This undertaking may be amended or
withdrawn at any time.

      Prior to April 28, 2003, OFS had voluntarily agreed to limit transfer and
shareholder servicing agent fees for all classes to 0.35% of average annual net
assets per class. Effective April 28, 2003, transfer agent fees for all classes
are limited to the lesser of 0.35% of average daily net assets or to an amount
necessary to allow each class of the Fund to maintain a 7-day yield of at least
approximately 0.10%. This undertaking may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
4. ILLIQUID SECURITIES

As of July 31, 2007, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Fund will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENTS

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
ACCOUNTING FOR INCOME TAXES. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the Fund's tax returns to determine whether it
is "more-likely-than-not" that tax positions taken in the Fund's tax return will
be ultimately sustained. A tax liability and expense must be recorded in respect
of any tax position that, in Management's judgment, will not be fully realized.
FIN 48 is effective for fiscal years beginning after December 15, 2006. As of
July 31, 2007, the Manager has evaluated the implications of FIN 48 and does not
currently anticipate a material impact to the Fund's financial statements. The
Manager will continue to monitor the Fund's tax positions prospectively for
potential future impacts.

      In September 2006, ("FASB") issued Statement of Financial Accounting
Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a
single authoritative


                         28 | OPPENHEIMER CASH RESERVES



definition of fair value, sets out a framework for measuring fair value and
expands disclosures about fair value measurements. SFAS No. 157 applies to fair
value measurements already required or permitted by existing standards. SFAS No.
157 is effective for financial statements issued for fiscal years beginning
after November 15, 2007, and interim periods within those fiscal years. As of
July 31, 2007, the Manager does not believe the adoption of SFAS No. 157 will
materially impact the financial statement amounts; however, additional
disclosures may be required about the inputs used to develop the measurements
and the effect of certain of the measurements on changes in net assets for the
period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER CASH RESERVES:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Cash Reserves (the "Fund"), including the statement of investments,
as of July 31, 2007, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Fund is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, 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. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of July 31, 2007, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Fund as of July 31, 2007, the results of its operations for the year then ended,
the changes in its net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the period
then ended, in conformity with accounting principles generally accepted in the
United States of America.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2008, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2007. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      Recent tax legislation allows a regulated investment company to designate
distributions not designated as capital gain distributions, as either interest
related dividends or short-term capital gain dividends, both of which are exempt
from the U.S. withholding tax applicable to non U.S. taxpayers. For the fiscal
year ended July 31, 2007, $40,057,405 or 99.975% of the ordinary distributions
paid by the Fund qualifies as an interest related dividend.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of
the complexity of the federal regulations which may affect your individual tax
return and the many variations in state and local tax regulations, we recommend
that you consult your tax advisor for specific guidance.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is an "interested person" as defined in
      the Investment Company Act of 1940; and whether the individual would be
      deemed an "audit committee financial expert" within the meaning of
      applicable SEC rules. The Committee also considers whether the
      individual's background, skills, and experience will complement the
      background, skills, and experience of other nominees and will contribute
      to the Board. There are no differences in the manner in which the
      Committee evaluates nominees for trustees based on whether the nominee is
      recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:

      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;



      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.

ITEM 11. CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 07/31/2007, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
