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

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

CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS

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 (2) ongoing costs, including management fees; distribution and
service 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 January 31, 2008.

ACTUAL EXPENSES. The first section of the table provides information about
actual account values and actual expenses. You may use the information in this
section 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 first section
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 second section of the table
provides 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 for each class before expenses, which is
not the 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 front-end
or 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" section of the table is 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.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios, based on
the 6-month period ended January 31, 2008 are as follows:

CLASS            EXPENSE RATIOS
- -------------------------------
Class A               0.88%
- -------------------------------
Class B               1.14
- -------------------------------
Class C               1.16
- -------------------------------
Class N               1.18

The expense ratios reflect reduction to custodian expenses and voluntary waivers
or reimbursements of expenses 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  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
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 adviser 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 72 months after the
date of purchase.

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. Securities are valued at cost adjusted by the amortization
of discount or premium to maturity (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.

- --------------------------------------------------------------------------------
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, including any net
realized gain on investments not offset by capital loss carryforwards, if any,
to shareholders. Therefore, no federal income or excise tax provision is
required. The Fund files income tax returns in U.S. federal and applicable state
jurisdictions. The statute of limitations on the Fund's tax return filings
generally remain open for the three preceding fiscal reporting period ends.

      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


                         24 | OPPENHEIMER CASH RESERVES



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.

      As of January 31, 2008, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $328 expiring by 2016. This
estimated capital loss carryforward represents carryforward as of the end of the
last fiscal year, increased for losses deferred under tax accounting rules to
the current fiscal year and is increased or decreased by capital losses or gains
realized in the first six months of the current fiscal year. During the six
months ended January 31, 2008, it is estimated that the Fund will not utilize
any capital loss carryforward to offset realized capital gains. During the
fiscal year ended July 31, 2007, the Fund did not utilize any capital loss
carryforward to offset capital gains realized in that fiscal year.

As of July 31, 2007, the Fund had available for federal income tax purposes
unused capital loss carryforward as follows:

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

- --------------------------------------------------------------------------------
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.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations and
may differ from U.S. generally accepted accounting principles, 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

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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 accounting
principles generally accepted in the United States of America 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 increases and
decreases in net assets from operations 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
were as follows:

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Under the investment advisory agreement, the Fund pays the
Manager a management fee based on the daily net assets of the Fund at an annual
rate as shown in the following table:

                        FEE SCHEDULE
                        -------------------------------
                        Up to $250 million       0.500%
                        Next $250 million        0.475
                        Next $250 million        0.450
                        Next $250 million        0.425
                        Over $1 billion          0.400

- --------------------------------------------------------------------------------
ADMINISTRATION SERVICE FEES. The Fund pays the Manager a fee of $1,500 per year
for preparing and filing the Fund's tax returns.

- --------------------------------------------------------------------------------
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 six months ended January 31, 2008, the
Fund paid $1,417,884 to OFS for services to the Fund.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's
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.

- --------------------------------------------------------------------------------
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.

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

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 fees of 0.25% and an annual asset-based sales charge of 0.25%.
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 including 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's
aggregate uncompensated expenses under the Plans at December 31, 2007 for Class
N shares were $7,708,024. 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 table below for the period indicated.

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 $314,881 for the six months ended January 31, 2008. This expense
limitation can be amended or terminated at any time without advance notice.

      Effective January 1, 2003, the Distributor 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 six months ended January 31, 2008, the Distributor waived
$147,803 and $293,842 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


                         28 | OPPENHEIMER CASH RESERVES



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 January 31, 2008, investments in securities included issues that are
illiquid. Investments may be illiquid because they do not have an active trading
market, making it difficult to value them or dispose of them promptly at an
acceptable price. 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 an applicable footnote
on the Statement of Investments.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENT

In September 2006, Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 157, FAIR VALUE
MEASUREMENTS. This standard establishes a single authoritative 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 January
31, 2008, 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.

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Fund's
investment advisory agreement (the "Agreement"). The Investment Company Act of
1940, as amended, requires that the Board request and evaluate, and that the
Manager provide, such information as may be reasonably necessary to evaluate the
terms of the Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information, that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services, (v) whether economies of scale
are realized as the Fund grows and whether fee levels reflect these economies of
scale for Fund investors and (vi) other benefits to the Manager from its
relationship with the Fund. Outlined below is a summary of the principal
information considered by the Board as well as the Board's conclusions.

      The Board was aware that there are alternatives to retaining the Manager.

      NATURE, QUALITY AND EXTENT OF SERVICES. The Board considered information
about the nature and extent of the services provided to the Fund and information
regarding the Manager's key personnel who provide such services. The Manager's
duties include providing the Fund with the services of the portfolio managers
and the Manager's investment team, who provide research, analysis and other
advisory services in regard to the Fund's investments; securities trading
services; oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.


                         30 | OPPENHEIMER CASH RESERVES



      The Board also considered the quality of the services provided and the
quality of the Manager's resources that are available to the Fund. The Board
took account of the fact that the Manager has had over forty years of experience
as an investment adviser and that its assets under management rank it among the
top mutual fund managers in the United States. The Board evaluated the Manager's
administrative, accounting, legal and compliance services, and information the
Board has received regarding the experience and professional qualifications of
the Manager's key personnel and the size and functions of its staff providing
investment management services to the Fund. In its evaluation of the quality of
the portfolio management services provided, the Board considered the experience
of Carol E. Wolf and Barry D. Weiss and the Manager's Money Market investment
team and analysts. Ms. Wolf has been the portfolio manager of the Fund since
July 1998 and Mr. Weiss has been the portfolio manager of the Fund since July
2001. The Board members also considered the totality of their experiences with
the Manager as directors or trustees of the Fund and other funds advised by the
Manager. In light of the foregoing, the Board concluded that the Fund benefits
from the services provided under the Agreement as a result of the Manager's
experience, reputation, personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each Board meeting, including comparative performance information.
The Board also reviewed information, prepared by the Manager and by the
independent consultant, comparing the Fund's historical performance to relevant
market indices and to the performance of other retail front-end load and no-load
money market funds (including both funds advised by the Manager and funds
advised by other investment advisers). The Board noted that the Fund's one-year,
three-year, five-year and ten-year performance was below its peer group median.
The Board considered the Manager's assertion that the difference between the
best performer and the worst performer in every time period is extremely limited
(about 1.6%) and that, on a gross performance basis, the Trust compares
favorably to its peers.

      COSTS OF SERVICES AND PROFITS REALIZED BY THE MANAGER. The Board
considered information regarding the Manager's costs in serving as the Fund's
investment adviser, including the costs associated with the personnel and
systems necessary to manage the Fund, and information regarding the Manager's
profitability from its relationship with the Fund. The Board reviewed the fees
paid to the Manager and the other expenses borne by the Fund. The Board also
considered the comparability of the fees charged and the services provided to
the Fund to the fees and services for other clients or accounts advised


                         31 | OPPENHEIMER CASH RESERVES



BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited / Continued
- --------------------------------------------------------------------------------

by the Manager. The independent consultant provided comparative data in regard
to the fees and expenses of the Fund and other money market funds with
comparable asset levels and distribution features. The Board noted that the
Manager has agreed to voluntarily limit the Fund's management fees to 0.40% of
the Fund's average annual net assets. This expense limitation may be withdrawn
or amended at any time. The Board noted that the Fund's contractual and actual
management fees are higher than its peer group median. The Board also noted that
the Fund's total expenses are higher than its peer group median, and considered
the Manager's assertion that this is primarily because the Fund has higher
transfer agent expenses. The higher transfer agent expenses result from the Fund
having a higher number of small accounts that its peers.

      ECONOMIES OF SCALE. The Board reviewed whether the Manager may realize
economies of scale in managing and supporting the Fund. The Board noted that the
Fund currently has management fee breakpoints, which are intended to share with
Fund shareholders economies of scale that may exist as the Fund's assets grow.

      OTHER BENEFITS TO THE MANAGER. In addition to considering the profits
realized by the Manager, the Board considered information that was provided
regarding the direct and indirect benefits the Manager receives as a result of
its relationship with the Fund, including compensation paid to the Manager's
affiliates. The Board also considered that the Manager must be able to pay and
retain experienced professional personnel at competitive rates to provide
quality services to the Fund and that maintaining the financial viability of the
Manager is important in order for the Manager to continue to provide significant
services to the Fund and its shareholders.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and to the independent Trustees. Fund counsel and the independent
Trustees' counsel are both independent of the Manager within the meaning and
intent of the Securities and Exchange Commission Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
decided to continue the Agreement for another year. In arriving at this
decision, the Board considered all of the above information, and considered the
terms and conditions of the Agreement, including the management fee, in light of
all of the surrounding circumstances.

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 01/31/2008, 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.
