RMA MUNICIPAL MONEY FUNDS                                         ANNUAL REPORT


                                                                August 21, 1998


Dear Shareholder,

   We are pleased to present you with the annual report for the PaineWebber
RMA California Municipal Money Fund, the PaineWebber RMA New York Municipal
Money Fund and the PaineWebber RMA New Jersey Municipal Money Fund for the
fiscal year ended June 30, 1998.

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

[GRAPHIC]  During the first half of 1998, the tax-exempt money markets
responded to both high volume and the growing influence of floating-rate
issues (longer-maturity bonds whose yields are reset weekly, making them the
equivalent of short-term obligations). These two forces restrained prices
through the period, and kept short-term municipal yields close to their normal
range (66-68%) as percentages of comparable-maturity, taxable securities.

     There was little incentive to extend portfolio maturity--longer maturity
securities did not offer much higher yields than shorter maturities.
Generally, high market volume lowers prices and raises yields in the one-year
market. That did not happen over the last six months because of the impact of
synthetic issues on the short end of the yield curve.

PORTFOLIO REVIEWS
- -------------------------------------------------------------------------------

[GRAPHIC] We had expected large cash inflows to bring interest rates down in 
July, and therefore had maintained the Funds' weighted-average maturities
slightly higher than those of their peers. (As interest rates fall, prices of
longer-maturity securities increase more than shorter maturities.) We extended
portfolio maturity by purchasing longer maturities where we found value.

- -------------------------------------------------------------------------------
PAINEWEBBER RMA CALIFORNIA MUNICIPAL MONEY FUND

     The Fund's current yield for the seven-day period ended June 30, 1998 was
2.7%. Its weighted-average maturity was 39 days, and net assets totaled $567.0
million as of June 30, 1998. The Fund did not invest in any securities subject
to the Federal alternative minimum tax for individual taxpayers.

- -------------------------------------------------------------------------------
PAINEWEBBER RMA NEW YORK MUNICIPAL MONEY FUND

     The Fund's current yield for the seven-day period ended June 30, 1998 was
2.8%. Its weighted-average maturity was 39 days, and net assets totaled $339.4
million as of June 30, 1998. The Fund did not invest in any securities subject
to the Federal alternative minimum tax for individual taxpayers.

- -------------------------------------------------------------------------------
PAINEWEBBER RMA NEW JERSEY MUNICIPAL MONEY FUND

     The Fund's current yield for the seven-day period ended June 30, 1998 was
2.6%. Its weighted-average maturity was 44 days, and net assets totaled $48.3
million as of June 30, 1998. The Fund did not invest in any securities subject
to the Federal alternative minimum tax for individual taxpayers.

                                                                               1

GENERAL OUTLOOK

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

[GRAPHIC] We remain positive on bonds despite recent volatility in the 
marketplace. The demand for U.S. debt remains high as the "flight to quality"
continues. We believe the Federal Reserve will hold monetary policy steady for
the foreseeable future due to the offsetting forces of a healthy domestic
economy and weak international economies, particularly in Asia.

     As the season for conventional note issuance wanes, we expect short-term
municipals to continue trading at average percentages of taxable yields.
Consequently, we do not expect to change our portfolio strategy over the next
six months.

     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.

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 when referred together with RMA California and RMA
New York collectively, 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 the 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. 

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, RMA California and RMA New York each pay 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, 1998, RMA California, RMA New York and RMA New Jersey owed 
PaineWebber $231,252, $138,896 and $20,805, respectively, for investment
advisory and administration fees.

                                                                             15

NOTES TO FINANCIAL STATEMENTS

     Mitchell Hutchins Asset Managment Inc. ("Mitchell Hutchins"), a wholly
owned asset management 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, 1998, PaineWebber voluntarily waived $5,113 
of its investment advisory and administration fees for RMA New York.

DISTRIBUTION PLAN

     PaineWebber is the distributor of each Fund's shares. Under the plans 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 certain shareholder services. PaineWebber was compensated
for providing such services at the annual rate of 0.12% of RMA New Jersey's
average daily net assets. For RMA California and RMA New York, PaineWebber was
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 through February 11,
1998. Effective February 12, 1998, upon Board of Trustee approval, this fee
became payable at the annual rate of 0.125% of RMA California's and RMA New
York's average daily net assets. At June 30, 1998, RMA California, RMA New
York and RMA New Jersey owed PaineWebber $61,494, 35,253 and $4,993,
respectively, for such service fees. 

TRANSFER AGENCY SERVICE FEES

     Prior to August 1, 1997, each Fund paid 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 Funds' transfer agent. For
these services for the month ended July 31, 1997, PaineWebber earned $4,546
and $3,402 in service fees from RMA California and RMA New York, respectively.

     Subsequent to July 31, 1997, PaineWebber provides transfer agency related
services to the Funds pursuant to a delegation of authority from PFPC, Inc.,
the Funds' transfer agent, and is compensated for these services by PFPC,
Inc., not the Funds. For the eleven months ended June 30, 1998, PaineWebber
received from PFPC, Inc., not the Funds, approximately 53%, 55% and 56% of the
total transfer agency and related service fees collected by PFPC, Inc. from
RMA California, RMA New York and RMA New Jersey, respectively. 

OTHER LIABILITIES

     At June 30, 1998, RMA California, RMA New York and RMA New Jersey had 
dividends payable aggregating $563,636, $354,197 and $44,430, respectively,
and RMA California and RMA New York had payables for investments purchased of
$44,593,201 and $10,012,000, 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, 1998, RMA California, RMA New York and RMA New Jersey had net
capital loss carryforwards of $228,787, $83,150 and $4,626, respectively.
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, 1999 and June 30, 2004, for RMA New York
between June 30, 1999 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, the gains so offset will not be distributed.

PAINEWEBBER MANAGED MUNICIPAL TRUST

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 statement 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, 1998 and the related statements of operations for the year then ended, the
statement of changes in net assets for each of the two years in the period
then ended 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, 1998 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, 1998, the results of
their operations for the year then ended, the changes in their net assets for
each of the two years in the period then ended and the financial highlights
for each of the indicated periods, in conformity with generally accepted
accounting principles.

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,
1998) as to the federal tax status of distributions received by shareholders
during such fiscal year. 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 14.30% of the
dividends paid subject to the federal alternative minimum tax for individual
taxpayers during the fiscal year. 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 calendar year, another
notification will be sent in respect of calendar year 1998. The second
notification, which will reflect the amount 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 1999. Shareholders are advised
to consult their own tax advisers with respect to the tax consequences of
their investment in each respective Fund.
