ITEM 1.  REPORTS TO STOCKHOLDERS.


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
OPPENHEIMERFUNDS, INC.

INVESTORS SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER
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 ADVISOR, CALLING US AT 1.800.525.7048 OR VISITING OUR WEBSITE AT

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, 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


                          9 | OPPENHEIMER CASH RESERVES


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

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.

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 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended January 31, 2007 are as follows:

CLASS              EXPENSE RATIOS
- ----------------------------------
Class A                 0.98%
- ----------------------------------
Class B                 1.22
- ----------------------------------
Class C                 1.27
- ----------------------------------
Class N                 1.21

The expense ratios reflect 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.

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 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.

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

      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.

      As of January 31, 2007, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $342 expiring by 2015. This
estimated capital loss carryforward represents carryforward as of the end of the
last fiscal year, increased for losses

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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. As of January 31, 2007, it is estimated that the Fund will
not utilize any capital loss carryforward to offset realized capital gains.
During the year ended July 31, 2006, the Fund did not utilize any capital loss
carryforward to offset capital gains realized in that fiscal year.

- --------------------------------------------------------------------------------
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,
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


                         24 | OPPENHEIMER CASH RESERVES


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.

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

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the
investment advisory agreement with the Fund which provides for a fee at an
annual rate of average net assets 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 or the Transfer Agent), 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, 2007, the Fund paid $1,507,076 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.

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


                         26 | OPPENHEIMER CASH RESERVES


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 December 31, 2006 for Class N shares were $6,633,630.
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.

January 31, 2007               $3,331           $24,585           $6,860            $7,672


- --------------------------------------------------------------------------------
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 $308,824 for the six months ended January 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 six months ended January 31, 2007, OFDI waived $156,332 and
$194,816 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 January 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
January 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, the 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, 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.

- --------------------------------------------------------------------------------
6. LITIGATION

A consolidated amended complaint was filed as a putative class action against
the Manager and the Transfer Agent and other defendants (including 51 of the
Oppenheimer funds excluding the Fund) in the U.S. District Court for the
Southern District of New York on January 10, 2005 and was amended on March 4,
2005. The complaint alleged, among other things, that the Manager charged
excessive fees for distribution and other costs, and that by permitting and/or
participating in those actions, the Directors/Trustees and the Officers of the
funds breached their fiduciary duties to fund shareholders under the Investment
Company Act of 1940 and at common law. The plaintiffs sought unspecified
damages, an accounting of all fees paid, and an award of attorneys' fees and
litigation expenses.

      In response to the defendants' motions to dismiss the suit, seven of the
eight counts in the complaint, including the claims against certain of the
Oppenheimer funds, as nominal defendants, and against certain present and former
Directors, Trustees and Officers of the funds, and the Distributor, as
defendants, were dismissed with prejudice, by court order dated March 10, 2006,
and the remaining count against the Manager and the Transfer Agent was dismissed
with prejudice by court order dated April 5, 2006. The plaintiffs filed an
appeal of those dismissals on May 11, 2006.


                         28 | OPPENHEIMER CASH RESERVES


      The Manager believes that the allegations contained in the complaint are
without merit and that there are substantial grounds to sustain the district
court's rulings. The Manager also believes that it is premature to render any
opinion as to the likelihood of an outcome unfavorable to it, the funds, the
Directors/Trustees or the Officers on the appeal of the decisions of the
district court, and that no estimate can yet be made with any degree of
certainty as to the amount or range of any potential loss.

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.

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

      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 Barry D. Weiss and Carol E. Wolf 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 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 were below its peer group median. The Board
also considered the Manager's statement that, in the Fund's peer group, small
performance differences can result in significantly different quintile rankings.
The Board considered that the difference between the best performer and the
worst performer in every time-period considered was less than 1.6%. The Board
also noted that, as of October 31, 2006, the Fund ranked in the third quintile
for the one-year period.

      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


                         32 | OPPENHEIMER CASH RESERVES


services provided to the Fund to the fees and services for other clients or
accounts advised 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 waive a portion of its management fee so that
the fees do not exceed an annual rate of 0.40% of the average annual net assets
for each class of shares. That undertaking may be amended or withdrawn at any
time. The Board noted that, while the Fund's contractual management fees are
higher than its peer group median, its actual management fees are lower than its
peer group median.

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

      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
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 did not single out any factor or factors as being more
important than others, but considered all of the factors together. The Board
judged 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.

Based on their evaluation of the registrant's disclosure controls and procedures

officer and principal financial officer found the registrant's disclosure
controls and procedures to provide reasonable assurances that information

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.
