Dear Fellow Shareholder:

You may have seen media coverage of market timing  allegations involving
Putnam Investments. A separate letter has been sent to you detailing the
steps being taken by Putnam Investments to address these matters. In
addition, the Board of Trustees of The Putnam Funds is conducting an
independent investigation of these issues. When that investigation is
complete, we will report to you on the steps we are taking to make sure
that nothing like this happens in the future. We will, of course, ensure
that your fund is fully compensated for any losses resulting from
improper trading activity at Putnam. We appreciate your loyalty and want
you to know that we intend to restore full confidence in Putnam, an
organization that aspires to the highest ethical and business standards.

The balance of this report focuses on the performance of your fund. In
the face of a persistently challenging interest-rate environment, Putnam
Money Market Fund was able to deliver positive results at net asset
value (NAV) for the fiscal year ended September 30, 2003. Though the
fund underperformed its benchmark index, class A shares at NAV
outperformed the fund's Lipper category average for the period. The
details are on the facing page.

When it comes to money market funds, differences in yields are measured
in fractions of percentage points. At the same time, the highest
standards of quality in the selection of securities must be maintained.
In the face of generally declining short-term interest rates, your
fund's management team continually works to try to lock in the highest
possible rates for the longest possible time, consistent with the fund's
strict selection criteria. In the following report, the managers discuss
their strategy during the fiscal year just ended and offer their views
on prospects for the months ahead.

Respectfully yours,

/S/ JOHN A. HILL              /S/ GEORGE PUTNAM, III

John A. Hill                  George Putnam, III
Chairman of the Trustees      President of the Funds

Performance commentary

Low interest rates proved to be the most decisive factor affecting the
performance of money market securities during the fund's fiscal year.
With short-term interest rates hovering around 40-year lows for much of
the 12 months ended September 30, 2003, it took a sharp, patient eye to
locate money-market-eligible securities with the right balance of
competitive income, quality, and maturity structure. In spite of the
flat-to-declining interest-rate environment, we managed to extend the
fund's average days to maturity -- thereby taking advantage of
attractive rates for longer periods of time -- while enhancing its
diversification mix. This enabled us to keep the fund's performance
competitive relative to its Lipper category, but was not enough to
enable the fund to match the returns of its benchmark index. As has been
our tradition, we strive not to sacrifice quality to capture relatively
higher-income securities, which can occur when investors place too high
a priority on yield. The fund's broad array of issuers and security
types also contributed to its success relative to its Lipper peer group.

FUND PROFILE

By emphasizing high-quality short-term fixed-income securities, Putnam
Money Market Fund seeks to protect principal by seeking to maintain a
constant $1.00 share price while providing shareholders with easy access
to their money. Putnam Money Market Fund may be appropriate for
investors seeking current income consistent with capital preservation,
stability of principal, and liquidity of assets.


Market overview

During the first half of the fund's fiscal year, disappointing levels of
economic growth and increasing tensions with Iraq gave rise to a
cautious Federal Reserve Board. As had been the case over the preceding
two years, economic and political uncertainty prompted uneasy investors
to focus on more predictable, high-quality investments. Money market
investments were a prime beneficiary of this more conservative
sentiment.

However, in the second half of the fiscal year, investor confidence
improved following the surprisingly brief war in Iraq and the
announcement of stronger economic data. With optimism returning to the
financial markets, investors began to reallocate assets out of
shorter-term, money market investments into equities. In addition, the
improving economic growth shifted the debate about the Federal Reserve
Board's future monetary policy from one of easing (i.e., lowering) to
one of tightening (i.e., increasing) short-term interest rates.

The prospect for higher rates caused the yield curve to steepen a bit
over the summer months, increasing the difference in yields between
shorter-term and longer-term securities. With shorter-term rates moving
a bit higher, we took advantage of the situation by extending the fund's
average days to maturity. By doing this, we believe we were able to lock
in as high a level of income as possible, given our investment
objectives.

Strategy overview

With the first half of the fund's fiscal year shrouded in much
uncertainty, we believed our best course of action was to position the
portfolio to minimize risk. Toward the summer months, our thinking began
to change as new data suggested that the Federal Reserve Board might
adopt a more neutral outlook or possibly raise interest rates. By
August, with the economy looking healthier, the yield curve steepened to
reflect investors' anticipation of a Fed tightening, and we decided to
institute a blended strategy. We purchased U.S. government agency notes
with maturities out to one year. By investing in these agency notes,
which are money-market-eligible securities, we were able to extend the
fund's average days to maturity. At the same time, to effectively manage
interest-rate risk, we balanced these purchases with shorter-term money
market securities from both U.S. and foreign issuers. From March 30, the
midpoint of the fund's fiscal year, to September 30, the average days to
maturity climbed from 59 days to 72 days. We achieved this extension
primarily through the purchase of U.S. government agency obligations,
which climbed from 6.8% of the fund's market value to 17.2% by September
30.

How sector allocations affected performance

In the flat-to-declining interest-rate environment, which characterized
your fund's fiscal year, issuers have taken advantage of their ability
to issue short-term, low-interest-rate debt. Investors benefit from this
situation, because a larger supply of money market issuance can provide
increased investment opportunities for your fund. One area of the money
market universe where issuance increased considerably during the last
half of your fund's fiscal year was the U.S. government obligations
market. The Federal National Mortgage Association (FNMA) and the Federal
Home Loan Bank (FHLB) increased their issuance of U.S. government agency
notes to meet the mortgage demand created by the ongoing refinancing
boom.

On the other hand, we continued to see a contraction of issuance in the
U.S. commercial paper market as a result of companies' preference to
avoid spending or investing during a slow economic period. Furthermore,
with interest rates so low across all fixed-income markets, many
businesses found it advantageous to issue intermediate-term bonds at
current rates rather than repeatedly issuing short-term debt and
assuming the risk of higher interest rates each time they came to market
with a new commercial paper issuance. We are pleased to see that many of
the credit issues that plagued this sector before the fiscal year began
appear to have been resolved and, in our opinion, prospects for this
market have improved considerably.

Asset-backed commercial paper, which represents 55% of the total commercial
paper market, comprises the largest component of the fund's domestic
commercial paper exposure. These instruments, which we believe are
relatively low risk, are investments backed by portfolios of highly
diversified assets. The diversification of the supporting assets, coupled
with additional structural protection, such as credit support from highly
rated banks, makes these securities, in our opinion, attractive,
high-quality investments.

  The net asset value of money market mutual funds is uninsured and
  designed to be fixed, while distributions vary daily. Investment returns
  will fluctuate.The principal value on passbook savings and on bank CDs
  is generally insured up to certain limits by state and federal agencies.
  Unlike stocks, which incur more risk, CDs offer a fixed rate of return.
  Unlike money market funds, bank CDs may be subject to substantial
  penalties for early withdrawals.

* Sources: FleetBoston (passbook savings), Federal Reserve Board of
  Governors (3-month CDs), and imoneynet's Money Fund Report (taxable
  money market fund compound 7-day yield).

Amstel Funding Corporation, Park Granada and Eureka Securitization rank
among the fund's largest issuers in this sector.

The fund's exposure to foreign money market instruments remained
relatively consistent throughout the fiscal year. ING NV and Nordea PLC,
two of the fund's larger issuers, are European financial institutions
that control significant market share in their respective home markets.
We believe both are well diversified, which has helped them maintain
their solid financial strength during difficult markets.

Please note that all holdings discussed in this report are subject to
review in  accordance with the fund's investment strategy and may vary

The fund's management team

The fund is managed by the Putnam Fixed-Income Money Market Team. The
members of the team are Joanne Driscoll (Portfolio Leader), Jonathan
Topper (Portfolio Member), Kevin Cronin, and Joyce Dragone.


The outlook for your fund

The following commentary reflects anticipated developments that could
affect your fund over the next six months, as well as your management
team's plans for responding to them.

As the new fiscal year begins, we are comfortable with the fund's
average days to maturity and do not anticipate extending it further at
this time. We think this level is prudent during what we see as a
transition period. We believe interest rates are likely to fluctuate at
current levels, until economic or geopolitical events dictate a more
decisive direction up or down. We expect to continue to ladder the
portfolio, that is, to spread assets relatively evenly across different
maturities in order to reduce risk.

Just as we have witnessed a flight-to-quality mentality among investors
during periods of uncertainty, we've seen investors lower their quality
standards in an effort to capture higher-yielding -- and lower-rated --
money market securities as economic conditions improve. Even as the
economy strengthens, we think this strategy is a dangerous tradeoff for
money market funds that seek to maintain a constant $1.00 share price.
As we search for money-market-eligible securities with attractive
income, we expect to keep our commitment to quality.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. Money market funds
are not insured or guaranteed by the Federal Deposit Insurance
Corporation (FDIC) or any other governmental agency. Although the fund
seeks to maintain a constant share price of $1.00, it is possible to
lose money by investing in this fund.

  Performance assumes reinvestment of distributions. None of the share
  classes carry an initial sales charge. Class B shares reflect the
  applicable contingent deferred sales charge (CDSC), which is 5% in the
  first year, declines to 1% in the sixth year, and is eliminated
  thereafter. Class C shares reflect a 1% CDSC for the first year that is
  eliminated thereafter. Class A, M, R, and T shares have no initial sales
  charge or CDSC. Performance for B, C, M, R, and T shares before their
  inception is derived from the historical performance of class A shares,
  adjusted for the applicable sales charge (or CDSC) and higher or lower
  operating expenses for such shares.

* The 7-day and 30-day yields are the two most common gauges for
  measuring money market mutual fund  performance. Yield more closely
  reflects current performance than total return.

Terms and definitions

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested
all distributions in the fund.

Net asset value (NAV) is the price, or value, of one share of a mutual
fund, without a sales charge. NAVs fluctuate with market conditions. The
NAV is calculated by dividing the net value of all the fund's assets by
the number of outstanding shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time
of the redemption of class B or C shares and assumes redemption at the
end of the period. Your fund's class B CDSC declines from a 5% maximum
during the first year to 1% during the sixth year. After the sixth year,
the CDSC no longer applies. The CDSC for class C shares is 1% for one
year after purchase.

Class A shares generally are fund shares purchased with an initial sales
charge. In the case of your fund, which has no sales charge, the
reference is to shares purchased or acquired through the exchange of
class A shares from another Putnam fund. Exchange of your fund's class A
shares into another fund may involve a sales charge, however.

Class B shares may be subject to a sales charge upon redemption.

Class C shares are not subject to an initial sales charge and are
subject to a contingent deferred sales charge only if the shares are
redeemed during the first year.

Class M shares generally have a lower initial sales charge and a higher
12b-1 fee than class A shares and no sales charge on redemption. In the
case of your fund, which has no sales charge, the reference is to shares
purchased or acquired through the exchange of class M shares from
another Putnam fund. Exchange of your fund's class M shares into another
fund may involve a sales charge, however.

Class R shares are not subject to an initial sales charge or CDSC and
are available only to certain defined  contribution plans.

Class T shares are not subject to an initial sales charge or sales
charge on redemption (except on certain redemptions of shares bought
without an initial sales charge); however, they are subject to a 12b-1
fee.

Putnam's policy on confidentiality

In order to conduct business with our shareholders, we must obtain
certain personal information such as account holders' addresses,
telephone numbers, Social Security numbers, and the names of their
financial advisors. We use this information to assign an account number
and to help us maintain accurate records of transactions and account
balances.

It is our policy to protect the confidentiality of your information,
whether or not you currently own shares of our funds, and in particular,
not to sell information about you or your accounts to outside marketing
firms. We have safeguards in place designed to prevent unauthorized
access to our computer systems and procedures to protect personal
information from unauthorized use.

Under certain circumstances, we share this information with outside
vendors who provide services to us, such as mailing and proxy
solicitation. In those cases, the service providers enter into
confidentiality agreements with us, and we provide only the information
necessary to process transactions and perform other services related to
your account. We may also share this information with our Putnam
affiliates to service your account or provide you with information about
other Putnam products or services. It is also our policy to share
account information with your financial advisor, if you've listed one on
your Putnam account.

If you would like clarification about our confidentiality policies or
have any questions or concerns, please don't hesitate to contact us at
1-800-225-1581, Monday through Friday, 8:30 a.m. to 7:00 p.m., or
Saturdays from 9:00 a.m. to 5:00 p.m. Eastern Time.


A guide to the financial statements

These sections of the report, as well as the accompanying Notes,
preceded by the Independent Auditors' Report, constitute the fund's
financial statements.

The fund's portfolio lists all the fund's investments and their values
as of the last day of the reporting period. Holdings are organized by
asset type and industry sector, country, or state to show areas of
concentration and diversification.

Statement of assets and liabilities shows how the fund's net assets and
share price are determined. All investment and noninvestment assets are
added together.  Any unpaid expenses and other liabilities are
subtracted from this total. The result is divided by the number of
shares to determine the net asset value per share, which is calculated
separately for each class of shares. (For funds with preferred shares,
the amount subtracted from total assets includes the net assets
allocated to remarketed preferred shares.)

Statement of operations shows the fund's net investment gain or loss.
This is done by first adding up all the fund's earnings -- from
dividends and interest income -- and subtracting its operating expenses
to determine net investment income (or loss).  Then, any net gain or
loss the fund realized on the sales of its holdings -- as well as any
unrealized gains or losses over the period -- is added to or subtracted
from the net investment result to determine the fund's net gain or loss
for the fiscal year.

Statement of changes in net assets shows how the fund's net assets were
affected by distributions to shareholders and by changes in the number
of the fund's shares. It lists distributions and their sources (net
investment income or realized capital gains) over the current reporting
period and the most recent fiscal year-end. The distributions listed
here may not match the sources listed in the Statement of operations
because the distributions are determined on a tax basis and may be paid
in a different period from the one in which they were earned.

Financial highlights provide an overview of the fund's investment
results,   per-share distributions, expense ratios, net investment
income ratios, and portfolio turnover in one summary table, reflecting
the five most recent reporting periods. In a semiannual report, the
highlight table also includes the current reporting period. For open-end
funds, a separate table is provided for each share class.


Independent auditors' report

To the Trustees and Shareholders of
Putnam Money Market Fund

In our opinion, the accompanying statement of assets and liabilities,
including the fund's portfolio, and the related statements of operations
and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of Putnam Money
Market Fund (the "fund") at September 30, 2003, and the results of its
operations, the changes in its net assets and the financial highlights
for the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the fund's management; our
responsibility is to express an opinion on these financial statements
based on our audits. We conducted our audits of these financial
statements in accordance with auditing standards generally accepted in
the United States of America, which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of investments owned at
September 30, 2003, by correspondence with the custodian, provide a
reasonable basis for our opinion.

Notes to financial statements
September 30, 2003

Note 1
Significant accounting policies

Putnam Money Market Fund (the "fund") is registered under the Investment
Company Act of 1940, as amended, as a diversified, open-end management
investment company. The fund seeks as high a rate of current income
consistent with preservation of capital and maintenance of liquidity.
The fund pursues its objective by investing in a portfolio of
high-quality short-term obligations. The fund may invest up to 100% of
its assets in money market instruments from the banking, personal credit
and  business credit industries.

The fund offers class A, class B, class C, class M, class R and class T
shares. The fund began offering class R shares on January 21, 2003. Each
class of shares is sold without a front-end sales charge. Class B and
class C shares are offered only in exchange for class B and class C
shares of other Putnam funds, or purchased by systematic investment
plans. Class B shares, which convert to class A shares after
approximately eight years, pay a higher ongoing distribution fee than
class A (which does not have an approved distribution fee), class M and
class T shares, and are subject to a contingent deferred sales charge,
if those shares are redeemed within six years of purchase (including any
holding period of the shares in other Putnam funds). Class C shares are
subject to the same fees and expenses as class B shares, except that
class C shares have a one-year 1.00% contingent deferred sales charge
and do not convert to class A shares. Shareholders who acquired class B
and class C shares through an exchange are subject to the same deferred
sales charge schedule as the fund from which they were exchanged. Class
M and class T shares pay an ongoing distribution fee that is higher than
class A shares but lower than class B, class C and class R shares and
are not subject to a contingent deferred sales charge. Class R shares
pay an ongoing distribution fee that is higher than class A, class M and
class T shares. Class R shares are offered to  qualified
employee-benefit plans.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if the fund were liquidated. In addition, the
Trustees declare separate dividends on each class of shares.

The following is a summary of significant accounting policies
consistently followed by the fund in the preparation of its financial
statements. The preparation of financial statements is in conformity
with accounting principles generally accepted in the United States of
America and requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities in 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.

A) Security valuation The valuation of the fund's portfolio instruments
is determined by means of the amortized cost method (which approximates
market value) as set forth in Rule 2a-7 under the Investment Company Act
of 1940. The amortized cost of an instrument is determined by valuing it
at its original cost and thereafter amortizing any discount or premium
from its face value at a constant rate until maturity.

B) Joint trading account The fund may transfer uninvested cash balances,
including cash collateral received under security lending arrangements,
into a joint trading account along with the cash of other registered
investment companies and certain other accounts managed by Putnam
Investment Management, LLC ("Putnam Management"), the fund's manager, an
indirect wholly-owned subsidiary of Putnam, LLC. These balances may be
invested in issuers of high-grade short-term investments having maturities
of up to 397 days for collateral received under security lending
arrangements and up to 90 days for other cash investments.

C) Repurchase agreements The fund, or any joint trading account, through
its custodian, receives delivery of the underlying securities, the
market value of which at the time of purchase is required to be in an
amount at least equal to the resale price, including accrued interest.
Collateral for certain tri-party repurchase agreements is held at the
counterparty's custodian in a segregated account for the benefit of the
fund and the counterparty. Putnam Management is responsible for
determining that the value of these underlying securities is at all
times at least equal to the resale price, including accrued interest.

D) Security transactions and related investment income Security
transactions are recorded on the trade date (the date the order to buy
or sell is executed). Interest is recorded on the accrual basis.
Premiums and discounts from purchases of short-term investments are
amortized/accreted at a constant rate until maturity. Gains or losses on
securities sold are determined on the identified cost basis.

E) Federal taxes It is the policy of the fund to distribute all of its
taxable income within the prescribed time and otherwise comply with the
provisions of the Internal Revenue Code applicable to regulated
investment companies. It is also the intention of the fund to distribute
an amount sufficient to avoid imposition of any excise tax under Section
4982 of the Internal Revenue Code of 1986, as amended. Therefore, no
provision has been made for federal taxes on income, capital gains or
unrealized appreciation on securities held nor for excise tax on income
and capital gains.

The aggregate identified cost on a financial reporting and tax basis is
the same.

F) Distributions to shareholders Income dividends are recorded daily by
the fund and are paid monthly to the shareholders. Distributions of
realized gains, if any, are paid at least annually.

Note 2
Management fee, administrative
services and other transactions

Putnam Management is paid for management and investment advisory
services quarterly based on the average net assets of the fund. Such fee
is based on the following annual rates: 0.50% of the first $100 million
of average net assets, 0.40% of the next $100 million, 0.35% of the next
$300 million, 0.325% of the next $500 million and 0.30% thereafter.

The fund reimburses Putnam Management an allocated amount for the
compensation and related expenses of certain officers of the fund and
their staff who provide administrative services to the fund. The
aggregate amount of all such reimbursements is determined annually by
the Trustees.

Custodial functions for the fund's assets are provided by Putnam
Fiduciary Trust Company (PFTC), a subsidiary of Putnam, LLC. Investor
servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

The fund has entered into an arrangement with PFTC whereby credits
realized as a result of uninvested cash balances are used to reduce a
portion of the fund's expenses. For the year ended September 30, 2003,
the fund's expenses were reduced by $327,608 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $4,268 has been allocated to the fund, and an additional fee for
each Trustees meeting attended. Trustees receive additional fees for
attendance at certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan"),
which allows the Trustees to defer the receipt of all or a portion of
Trustees fees payable on or after July 1, 1995. The deferred fees remain
invested in certain Putnam funds until distribution in accordance with
the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have served
as a Trustee for at least five years. Benefits under the Pension Plan are

Note 5
Regulatory matters and litigation

On November 13, 2003, Putnam Management agreed to entry of an order by the
Securities and Exchange Commission in partial resolution of administrative
and cease-and-desist proceedings initiated by the SEC on October 28, 2003
in connection with alleged excessive short-term trading by certain
investment professionals. Under the order, Putnam Management will make
restitution for losses attributable to excessive short-term trading by
Putnam employees, institute new employee trading restrictions and enhanced
employee trading compliance, retain an independent compliance consultant,
and take other remedial actions. Putnam Management neither admitted nor
denied the order's findings that it willfully violated provisions of the
securities laws. A civil monetary penalty and other monetary relief, if
any, will be determined at a later date. Putnam Management, and not the
investors in any Putnam fund, will bear all costs, including restitution,
civil penalties and associated legal fees. Administrative proceedings
initiated by the Commonwealth of Massachusetts on October 28, 2003 against
Putnam Management in connection with alleged market timing activities by
Putnam employees and by participants in some Putnam-administered 401(k)
plans are pending. The SEC's and Commonwealth's allegations also serve as
the general basis for numerous lawsuits, including purported class action
lawsuits, filed against Putnam Management and certain related parties,
including certain open-end Putnam funds. Putnam Management has agreed to
bear any reasonable legal costs incurred by the Putnam funds in connection
with defending these lawsuits. Based on currently available information,
Putnam Management believes that the likelihood that the pending actions
will have a material adverse financial impact on the fund is remote, and
that the pending actions are not likely to materially affect its ability to
provide investment management services to its clients, including the Putnam
funds.

Review of these matters by counsel for Putnam Management and by separate
independent counsel for the Putnam funds and their independent Trustees
is continuing. In addition, Marsh & McLennan Companies, Inc., Putnam
Management's parent company, has engaged counsel to conduct a separate
review of Putnam Management's trading policies and controls. Putnam
Management has committed to make complete restitution for any losses
suffered by Putnam shareholders as a result of any improper
market-timing activities by Putnam employees or within
Putnam-administered 401(k) plans.

Item 2. Code of Ethics:
- -----------------------
All officers of the Fund, including its principal executive, financial and
accounting officers, are employees of Putnam Investment Management, LLC,
the Fund's investment manager.  As such they are subject to a comprehensive
Code of Ethics adopted and administered by Putnam Investments which is
designed to protect the interests of the firm and its clients.  The Fund
has adopted a Code of Ethics which incorporates the Code of Ethics of
Putnam Investments with respect to all of its officers and Trustees who are
employees of Putnam Investment Management, LLC.  For this reason, the Fund
has not adopted a separate code of ethics governing its principal
executive, financial and accounting officers.

Item 3. Audit Committee Financial Expert:
- -----------------------------------------
The Funds' Audit and Pricing Committee is comprised solely of Trustees
who are "independent" (as such term has been defined by the Securities
and Exchange Commission ("SEC") in regulations implementing Section 407
of the Sarbanes-Oxley Act (the "Regulations")).  The Trustees believe
that each of the members of the Audit and Pricing Committee also possess
a combination of knowledge and experience with respect to financial
accounting matters, as well as other attributes, that qualify them for
service on the Committee.  In addition, the Trustees have determined
that all members of the Funds' Audit and Pricing Committee meet the
financial literacy requirements of the New York Stock Exchange's rules
and that Mr. Patterson and Mr. Stephens qualify as "audit committee
financial experts" (as such term has been defined by the Regulations)
based on their review of their pertinent experience and education.
Certain other Trustees, although not on the Audit and Pricing Committee,
would also qualify as "audit committee financial experts."  The SEC has
stated that the designation or identification of a person as an audit
committee financial expert pursuant to this Item 3 of Form N-CSR does
not impose on such person any duties, obligations or liability that are
greater than the duties, obligations and liability imposed on such
person as a member of the Audit and Pricing Committee and the Board of
Trustees in the absence of such designation or identification.

Item 4. Principal Accountant Fees and Services:
- -----------------------------------------------
Not applicable

Items 5-6. [Reserved]

Item 9. Controls and Procedures:
- --------------------------------

(a) The registrant's principal executive officer and principal financial
officers have concluded, based on their evaluation of the effectiveness
of the design and operation of the registrant's disclosure controls and
procedures as of a date within 90 days of the filing date of this report
on Form N-CSR, that the design and operation of such procedures are
effective to provide reasonable assurance that information required to
