Total returns include changes in share price and reinvestment of dividends and
capital gains distributions in a hypothetical investment for the periods shown.
Cumulative total returns are not annualized. The Fund's total returns shown do

may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares. 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 WWW.OPPENHEIMERFUNDS.COM. READ THE
PROSPECTUS CAREFULLY BEFORE INVESTING.

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

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
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 August 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 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" 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.

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,
excluding all underlying fund expenses, based on the 6-month period ended August
31, 2007 are as follows:

CLASS              EXPENSE RATIOS
- ---------------------------------
Class A                 0.90%
- ---------------------------------
Class B                 1.65
- ---------------------------------
Class C                 1.65
- ---------------------------------
Class N                 1.06
- ---------------------------------
Class Y                 0.62

The expense ratios reflect reduction to custodian expenses and voluntary waivers
or reimbursements by the Fund's Manager and Transfer Agent 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.

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Transition 2010 Fund (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 total return until the target
retirement date included in its name and then seeks income and secondarily
capital growth. The Fund is a special type of mutual fund known as a "fund of
funds" because it invests in other mutual funds. The Fund normally invests in a
portfolio consisting of a target weighted allocation in Class A or Class Y
shares of other Oppenheimer funds (the "Underlying Funds"). The Fund's
investment advisor is OppenheimerFunds, Inc. (the "Manager").

      The Fund offers Class A, Class B, Class C, Class N and Class Y shares.
Class A shares are sold at their offering price, which is normally net asset
value plus a front-end 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. Class Y shares are sold to certain institutional investors without
either a front-end sales charge or a CDSC, however, the institutional investor
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. No such plan has been adopted for
Class Y shares. 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. The Fund calculates the net asset value of each class of
shares based upon the net asset value of the applicable Underlying Funds. For
each Underlying Fund, the net asset value per share for a class of shares on a
"regular business day" is determined by dividing the value of the Underlying
Fund's net assets attributable to that class by the number of shares of that
class outstanding on that day. To determine net asset values, the Underlying
Fund assets are valued primarily on the basis of current market quotations. If
market quotations are not readily available or do not accurately reflect fair
value for a security (in the Manager's judgment) or if a security's value has
been materially affected by events occurring after the close of the exchange or
market on which the security is principally traded, that security may be valued
by another method that the Underlying Fund's Board of Trustees/Directors
believes accurately reflects the fair value. Because some foreign securities
trade in markets and on exchanges that operate on weekends and U.S. holidays,
the values of some of the Underlying Fund's foreign investments may change on
days when investors cannot buy or redeem Underlying Fund shares.

      Short-term "money market type" debt securities with remaining maturities
of sixty days or less are valued at amortized cost (which approximates market
value).

1. SIGNIFICANT ACCOUNTING POLICIES Continued

INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Fund is permitted
to invest daily available cash balances in an affiliated money market fund. The
Fund may invest the available cash in Class E shares of Oppenheimer
Institutional Money Market Fund ("IMMF") which seeks current income and
stability of principal. IMMF is a registered open-end management investment
company, regulated as a money market fund under the Investment Company Act of
1940, as amended. The Manager is also the investment advisor of IMMF. The Fund's
investment in IMMF is included in the Statement of Investments, if applicable.
As a shareholder, the Fund is subject to its proportional share of IMMF's Class
E expenses, including its management fee. The Manager will waive fees and/or
reimburse Fund expenses in an amount equal to the indirect management fees
incurred through the Fund's investment in IMMF.

- --------------------------------------------------------------------------------
RISKS OF INVESTING IN THE UNDERLYING FUNDS. Each of the Underlying Funds in
which the Fund invests has its own investment risks, and those risks can affect
the value of the Fund's investments and therefore the value of the Fund's
shares. To the extent that the Fund invests more of its assets in one Underlying
Fund than in another, the Fund will have greater exposure to the risks of that
Underlying Fund.

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

      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 August 31, 2007, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $1,283 expiring by 2015. 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. As of August 31,
2007, it is estimated that the Fund will not utilize any capital loss
carryforward to offset realized capital gains. During the fiscal year ended
February 28,


                      26 | OPPENHEIMER TRANSITION 2010 FUND



2007, the Fund did not utilize any capital loss carryforward to offset capital
gains realized in that fiscal year.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan (the
"Plan") for the Fund's independent trustees. Benefits are based on years of
service and fees paid to each trustee during their period of service. The Plan
was frozen with respect to adding new participants effective December 31, 2006
(the "Freeze Date") and existing Plan Participants as of the Freeze Date will
continue to receive accrued benefits under the Plan. Active independent trustees
as of the Freeze Date have each elected a distribution method with respect to
their benefits under the Plan. During the six months ended August 31, 2007, the
Fund's projected benefit obligations were increased by $8 and payments of $14
were made to retired trustees, resulting in a liability of zero as of August 31,
2007.

      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 and capital gain distributions, if
any, are declared and paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

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

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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.

the Fund for the six months ended August 31, 2007 were 0.54%.

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

$1,041 to OFS for services to the Fund.

      Additionally, Class Y shares are subject to minimum fees of $10,000 per

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 those shares and servicing accounts. Under the plans, the Fund
pays the Distributor an annual asset-based sales charge of 0.75% on Class B and
Class C shares and 0.25% on Class N shares. The Distributor also receives a
service fee of 0.25% per year under each plan. 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
for Class B, Class C and Class N shares were $4,150, $2,648 and $7,114,
respectively. Fees incurred by the Fund under the plans are detailed in the
Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and contingent deferred sales charges
(CDSC) do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period
indicated.

WAIVERS AND REIMBURSEMENTS OF EXPENSES. The Manager has voluntarily agreed to a
total expense limitation on the aggregate amount of combined direct
(fund-of-funds level) and indirect expense so that as a percentage of average
daily net assets they will not exceed the following annual rates: 1.50%, 2.25%,
2.25%, 1.75% and 1.25%, for Class A, Class B, Class C, Class N and Class Y,
respectively. During the six months ended August 31, 2007, the Manager
reimbursed the Fund $2,686, $1,521, $2,596, $248 and $43 for the Class


                      30 | OPPENHEIMER TRANSITION 2010 FUND



A, Class B, Class C, Class N and Class Y shares, respectively. The Manager may
modify or terminate this undertaking at any time without notice to shareholders.

      OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average annual net assets per class.
During the six months ended August 31, 2007, OFS waived $65 for Class B shares.
This undertaking may be amended or withdrawn at any time.

      The Manager will waive fees and/or reimburse Fund expenses in an amount
equal to the indirect management fees incurred through the Fund's investment in
IMMF. During the six months ended August 31, 2007, the Manager waived $27 for
IMMF management fees.

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

In September 2006, Financial Accounting Standards Board 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 August 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.

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 by the Manager and its affiliates,
(v) the extent to which 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. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE 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 asset allocation team, who provide research, analysis and other
advisory services in regard to the Fund's investments; 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.

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

      QUALITY OF SERVICES. 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 personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Rudi
Schadt, Jerry Webman and Kurt Wolfgruber, the portfolio managers of the Fund,
and the experience of the portfolio managers and the investment performance of
the investment companies in which the Fund may invest (the "Underlying Funds").
The Board members also considered their experiences with the Manager and its
officers and other personnel through their service on the Boards of the Fund and
other funds advised by the Manager. The Board considered information regarding
the quality of services provided by affiliates of the Manager, which its members
have become knowledgeable about in connection with the renewal of the Fund's
service agreements. In light of the foregoing, the Board concluded that the Fund
benefits from the services provided under the Agreement and from the Manager's
experience, reputation, personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE FUND. The Manager provided information on
the year-to-date investment performance of the Fund, including comparative
information indicating that the Fund's year-to-date performance was better than
its peer group. Performance information was not available for any longer period
since the Fund has not yet completed a full year of operations.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
noted that the Fund does not pay a direct management fee but that the Fund
indirectly bears its share of the management fees of the Underlying Funds. 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 by the Manager. The independent consultant provided comparative data in
regard to the fees and expenses of the Fund, other mixed-asset target 2010 funds
of funds and other funds of funds with comparable asset levels and distribution
features. The Board noted that the Manager has agreed to voluntarily limit the
aggregate amount of combined direct (fund-of-funds level) and indirect expense
so that as a percentage of average daily net assets they will not exceed the
following annual

rates: 1.50% for Class A, 2.25% for Class B, 2.25% for Class C, 1.75% for Class
N and 1.25% for Class Y. The Manager may modify or terminate this undertaking at
any time without notice to shareholders. The Board noted that the Fund's total
direct and indirect expenses are higher than its peer group median.

      ECONOMIES OF SCALE. The Board considered the extent to which the Manager
may realize economies of scale in managing and supporting the Fund and the
Underlying Funds, and the extent to which those economies of scale would benefit
the Fund's shareholders.

      BENEFITS TO 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 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. In addition to considering the profits
realized by the Manager, the Board considered information regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager and its affiliates for
services provided to the Fund and to the Underlying Funds.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and the independent Trustees. Fund counsel is 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,
concluded that the nature, extent and quality of the services provided to the
Fund by the Manager are a benefit to the Fund and in the best interest of the
Fund's shareholders and that the amount and structure of the compensation
received by the Manager and its affiliates are reasonable in relation to the
services provided. Accordingly, the Board elected 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.



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 08/31/2007, 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.

         (2) Exhibits attached hereto.
