RMA MUNICIPAL MONEY FUNDS                                          ANNUAL REPORT

                                                                 August 20, 1997

Dear Shareholder, 

     We are pleased to present you with the annual report for PaineWebber RMA
California Municipal Money Fund, PaineWebber RMA New York Municipal Money Fund
and PaineWebber RMA New Jersey Municipal Money Fund for the fiscal year ended
June 30, 1997.

GENERAL MARKET OVERVIEW
- --------------------------------------------------------------------------------

     Early in the period, uncertainty over the direction of interest rates
unsettled what was already a jittery bond market. By mid-summer 1996, a
moderating economy helped bolster the market for a short period of time, a
situation that was, however, only fleeting as renewed fears of an overheating
economy quickly re-emerged. This pattern would repeat itself throughout fall and
into the new year. 

     The Federal Reserve's (the "Fed") decision to raise short-term interest
rates to 5.5% in March resulted in virtually every bond sector posting a
negative total return at the end of the first quarter of 1997. The high yield
sector was the exception, as gains in January and February more than offset the
softness following the Fed move. Then, on April 28, 1997, the report of the
Employment Cost Index (ECI)-- considered to be the most comprehensive
wage-inflation indicator, and critical to Fed policy--indicated a very positive
inflation picture. This information, plus positive news on an agreed upon
framework by President Clinton and the Republicans to balance the budget by
2002, and an atypical paydown in federal debt, turned market sentiment extremely
bullish. Bonds rallied strongly, sending the yield on the long bond from 7.1% on
March 31, 1997 to 6.8% on June 30, 1997. Furthermore, all fixed income sectors
contributed positively to total performance; however, the high yield sector
again outperformed others as investors' willingness to accept higher credit risk
produced higher returns. 

                                                                               1

OUTLOOK
- --------------------------------------------------------------------------------

     As we enter the second half of 1997, the emerging view on the economy has
been for a slowdown in growth rates. While bond market participants have, over
the period, acquired a greater confidence in the Fed's management of monetary
policy, more critically abetting the market's runup has been a widening
perception that the Greenspan Fed is likely to be pragmatic--and not driven
strictly by classical resource utilization-based economic thought that currently
argues for aggressive monetary tightening. This, in fact appears to be the case,
as evidenced by the Federal Reserve's decision not to move on interest rates at
the Federal Open Market Committee meeting on August 19, 1997.

     Although we plan to maintain the Funds' current postures, every new
economic number released will be closely scrutinized. Inflation is always a
concern and, as such, will be carefully monitored. Investment decisions for the
Funds will continue to be dominated by credit, quality and liquidity. Although
we are interested in maintaining higher yields, we will not do so by sacrificing
the Funds' emphasis on credit, quality and liquidity.

     Our ultimate objective in managing your investments is to help you
successfully meet your financial goals. We thank you for your continued support,
and welcome any comments or questions you may have.

Sincerely, 

/s/ MARGO N. ALEXANDER             /s/ DENNIS L. McCAULEY

NOTES TO FINANCIAL STATEMENTS
 
ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
    PaineWebber Managed Municipal Trust ('Managed Municipal Trust') and
PaineWebber Municipal Money Market Series ('Municipal Money Market Series')
(collectively, the 'Trusts') were organized under Massachusetts law by
Declarations of Trust dated November 21, 1986 and September 14, 1990,
respectively, and are registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended, as open-end management
investment companies. Managed Municipal Trust currently offers two no-load,
non-diversified series of shares: PaineWebber RMA California Municipal Money
Fund ('RMA California') and PaineWebber RMA New York Municipal Money Fund ('RMA
New York'). Municipal Money Market Series currently offers one no-load,
non-diversified series of shares: PaineWebber RMA New Jersey Municipal Money
Fund ('RMA New Jersey') and, together with RMA California and RMA New York, the
('Funds').
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires Fund management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from those estimates. Following is a
summary of significant accounting policies:
 
    Valuation and Accounting for Investments and Investment Income--Investments
are valued at amortized cost which approximates market value. Investment
transactions are recorded on the trade date. Realized gains and losses from
investment transactions are calculated using the identified cost method.
Interest income is recorded on an accrual basis. Premiums are amortized and
discounts are accreted as adjustments to interest income and the identified cost
of investments.
 
    Dividends and distributions--Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of dividends and distributions is
determined in accordance with federal income tax regulations, which may differ
from generally accepted accounting principles. These 'book/tax' differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification.
 
CONCENTRATION OF RISK
 
    Each Fund follows an investment policy of investing primarily in municipal
obligations of one state. Economic changes affecting the state and certain of
its public bodies and municipalities may affect the ability of issuers within
the state to pay interest on, or repay principal of, municipal obligations held
by each Fund.
 
ACQUISITIONS
 
    Acquisition of PaineWebber/Kidder, Peabody California Tax-Exempt Money Fund

('PW/KP California Tax-Exempt Money Fund')--Effective December 11, 1995, RMA
California acquired all the net assets of PW/KP California Tax-Exempt Money Fund
pursuant to a plan of reorganization approved by PW/KP California Tax-Exempt
Money Fund shareholders on December 4, 1995. The acquisition was accomplished by
a tax-free exchange of 120,122,110 shares of RMA California for 120,122,110
shares of PW/KP California Tax-Exempt Money Fund outstanding on December 11,
1995. PW/KP California Tax-Exempt Money Fund's net assets at that date, valued
at $120,039,530, including accumulated net realized losses of $26,217, were
combined with those of RMA California.

Series')--Effective November 13, 1995, RMA New York acquired all the net assets
of PW/KP Municipal Money Market Series--New York Series pursuant to a plan of
reorganization approved by PW/KP Municipal Money Market Series--New York Series
shareholders on November 8, 1995. The acquisition was accomplished by a tax-free
exchange of 38,947,877 shares of RMA New York for 38,947,877 shares of PW/KP

INVESTMENT ADVISER AND ADMINISTRATOR
 
    Each Trust's board of trustees has approved an Investment Advisory and
Administration Contract ('Advisory Contracts') with PaineWebber Incorporated
('PaineWebber'), under which PaineWebber serves as investment adviser and
administrator of the Trusts and each of their Funds. In accordance with their
Advisory Contracts, each of RMA California and RMA New York pays PaineWebber an
investment advisory and administration fee, which is accrued daily and paid
monthly in accordance with the following schedule:
 
                                                                       ANNUAL
        AVERAGE DAILY NET ASSETS                                        RATE
        ------------------------------------------------------------   ------
        Up to $300 million..........................................    0.50%
        In excess of $300 million up to $750 million................    0.44
        Over $750 million...........................................    0.36
 
    In accordance with its Advisory Contract, RMA New Jersey pays PaineWebber an
investment advisory and administration fee, which is accrued daily and paid
monthly, at an annual rate of 0.50% of the Fund's average daily net assets.
 
    At June 30, 1997, RMA California, RMA New York and RMA New Jersey owed
PaineWebber $198,104, $103,853 and $22,185, respectively, for investment
advisory and administration fees.
 
    Mitchell Hutchins Asset Management Inc. ('Mitchell Hutchins'), a wholly

owned subsidiary of PaineWebber, serves as sub-adviser and sub-administrator of
the Funds pursuant to a sub-advisory and sub-administration contract between
PaineWebber and Mitchell Hutchins. In accordance with that contract, PaineWebber
(not the Funds) pays Mitchell Hutchins a fee, accrued daily and paid monthly, at
an annual rate of 20% of the fee paid by the Funds to PaineWebber under the
Advisory Contract.
 
    For the year ended June 30, 1997, PaineWebber voluntarily waived $292,698 of
its investment advisory and administration fees for RMA New York.
 
DISTRIBUTION PLAN
 
    PaineWebber is the distributor of each Fund's shares. Under the plan of
distribution, the Funds are authorized to pay PaineWebber a monthly service fee
at the annual rate of up to 0.15% of RMA California's and RMA New York's average
daily net assets and 0.12% of RMA New Jersey's average daily net assets for
providing shareholder services and maintaining shareholder accounts. Currently,
PaineWebber is compensated for providing such services at the annual rate of
0.08% of RMA California's and RMA New York's average daily net assets and 0.12%
of RMA New Jersey's average daily net assets. At June 30, 1997, RMA California,
RMA New York and RMA New Jersey owed PaineWebber $33,329, $18,359 and $5,324,
respectively, for such service fees.
 
                                       16

NOTES TO FINANCIAL STATEMENTS
 
TRANSFER AGENCY SERVICE FEES
 
    RMA California and RMA New York pay PaineWebber an annual fee of $4.00 per
active PaineWebber shareholder account, plus certain out-of-pocket expenses, for
certain services not provided by the Fund's transfer agent. For the year ended
June 30, 1997, PaineWebber earned $54,029 and $39,481 in transfer agency service
fees from RMA California and RMA New York, respectively. At June 30, 1997, RMA
California and RMA New York owed PaineWebber $4,477 and $3,351, respectively,
for such transfer agency service fees and reimbursement of out-of-pocket
expenses.
 
OTHER LIABILITIES
 
    At June 30, 1997, RMA California, RMA New York and RMA New Jersey had
dividends payable aggregating $519,020, $296,399 and $54,611, respectively, and
RMA California and RMA New York had payables for investments purchased of
$31,987,309 and $8,528,880, respectively.
 
FEDERAL TAX STATUS
 
    Each Fund intends to distribute all of its tax-exempt income and any taxable
income and to comply with the other requirements of the Internal Revenue Code
applicable to regulated investment companies. Accordingly, no provision for
federal income taxes is required. In addition, by distributing during each
calendar year substantially all of its net investment income, capital gains and

certain other amounts, if any, each Fund intends not to be subject to a federal
excise tax.
 
    At June 30, 1997, RMA California had net capital loss carryforwards of
$280,026 which includes capital losses acquired by the Fund pursuant to its
acquisition of PW/KP California Tax Exempt Money Fund in the amount of $26,217.
RMA New York had net capital loss carryforwards of $97,826 which includes losses
acquired by the Fund pursuant to its acquisition of PW/KP Municipal Money Market
Series--New York Series in the amount of $5,141. RMA New Jersey had a net
capital loss carryforward of $4,626. These loss carryforwards are available as
reductions, to the extent provided in the regulations, of future net realized
capital gains, and will expire for RMA California between June 30, 1998 and June
30, 2004, for RMA New York between June 30, 1998 and June 30, 2003 and for RMA
New Jersey between June 30, 2002 and June 30, 2005. To the extent these losses
are used to offset future capital gains, it is probable that the gains so offset
will not be distributed.

PAINEWEBBER MUNICIPAL MONEY MARKET SERIES
 
REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Trustees and Shareholders
PaineWebber Managed Municipal Trust
PaineWebber Municipal Money Market Series
 
We have audited the accompanying statements of net assets of PaineWebber Managed
Municipal Trust (comprising, respectively, the PaineWebber RMA California
Municipal Money Fund and PaineWebber RMA New York Municipal Money Fund) and
PaineWebber Municipal Money Market Series (comprising, PaineWebber RMA New
Jersey Municipal Money Fund), (collectively, the 'Funds'), as of June 30, 1997,
and the related statements of operations for the year then ended, the statement
of changes in net assets and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
investments owned at June 30, 1997 by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective Funds constituting the PaineWebber Managed Municipal Trust and
PaineWebber Municipal Money Market Series at June 30, 1997, the results of their
operations for the year then ended, the changes in their net assets and the
financial highlights for each of the indicated periods, in conformity with
generally accepted accounting principles.

                                                         /S/ ERNST & YOUNG LLP

TAX INFORMATION--(UNAUDITED)
 
   We are required by Subchapter M of the Internal Revenue Code of 1986, as
amended, to advise you within 60 days of each Fund's fiscal year end (June 30,
1997) as to the federal tax status of distributions received by shareholders
during such fiscal period. Accordingly, we are advising you that all dividends
paid during the period by RMA California, RMA New York and RMA New Jersey were
federally exempt interest dividends. RMA New Jersey had 15.31% of the dividends
paid subject to the federal alternative minimum tax for individual taxpayers
during the period. Also, all dividends paid by the Funds were exempt from
personal income taxes from their respective States.
 
   Because each Fund's fiscal year is not the calender year, another
notification will be sent in respect of calendar year 1997. The second
notification, which will reflect any amounts to be used by calendar year
taxpayers on their federal income tax returns, will be made in conjunction with
Form 1099 DIV and will be mailed in January 1998. Shareholders are advised to
consult their own tax advisers with respect to the tax consequences of their
investment in each respective Fund.
