AN INTERVIEW WITH PORTFOLIO MANAGERS SUSAN RYAN AND DEBBIE BAGGETT Q. HOW DID THE FUNDS PERFORM DURING THE PERIOD? A. Short-term interest rates fell during the period. As a result, when the holdings in the funds' portfolios matured, they had to be replaced with securities that offered lower yields. Therefore, the Funds' seven-day current yields declined during the fiscal year. As of June 30, 2003, they were: UBS RMA Money Market Portfolio--0.55%; UBS RMA U.S. Government Portfolio--0.58%; UBS RMA Tax-Free Fund Inc.--0.39%; UBS RMA California Municipal Money Fund--0.39%; UBS RMA New York Municipal Money Fund--0.35%; and UBS RMA New Jersey Municipal Money Fund--0.23%. (For more on the Funds' and Portfolios' performance, refer to "Performance At A Glance" on page 5.) Q. CAN YOU DESCRIBE THE ECONOMIC ENVIRONMENT DURING THE REPORTING PERIOD? A. Other than a brief revival during the third quarter of 2002, the US economy was generally weak during the funds' fiscal year. As the reporting period began in July 2002, the economy appeared to be moving in the right direction. Gross domestic product (GDP) rose 4.0% during the third quarter of 2002, following an anemic 1.7% rate in the prior quarter. This growth spurt was short lived, though, as the prospect of a war in Iraq, heightened threats of terrorism, turmoil in the Middle East, tepid corporate spending and a weak stock market all served [SIDENOTE] UBS RMA MONEY MARKET PORTFOLIO, UBS RMA U.S. GOVERNMENT PORTFOLIO INVESTMENT GOAL (BOTH PORTFOLIOS): Maximum current income consistent with preservation of capital and liquidity.

GDP fell to 1.4% during the last three months of 2002, and remained unchanged in the first quarter of 2003. Q. WHAT ARE SOME OF THE REASONS BEHIND THE TEPID ECONOMIC GROWTH? A. Throughout 2002, consumer spending, which accounts for two-thirds of the US economy, was relatively strong. This was in sharp contrast to corporate spending, which continued to be subdued as many companies postponed major purchases pending clearer signs of a sustainable economic recovery. However, in early 2003, both consumer and corporate spending weakened. Geopolitical concerns, a spike in oil prices, rising unemployment, and severe weather in parts of the country served to further undermine the economy. In the aftermath of major conflict in Iraq, no clear spending picture has emerged. Q. HOW DID THE FEDERAL RESERVE BOARD (THE "FED") REACT TO THE WEAKENING ECONOMY? A. During the first four months of the reporting period, the Fed kept rates steady. Then, at its November 2002 meeting, the Fed, acknowledging that the economy had hit a "soft spot," lowered the federal funds rate one half of a percentage point to 1.25%. In the months that followed, the Fed deferred from making additional rate cuts, although it made it clear that it was assuming a "heightened surveillance" of the economy in light of the conflict with Iraq. After the war's start, however, and absent any lift in the economy, the Fed alluded to the possibility of a future rate cut, citing that it viewed economic weakness to be a greater risk than inflation. Many took the statement to mean that a rate cut would likely be implemented at the Fed's next meeting. It came as no surprise, then, when, in an endnote to the period, the Fed moved to lower the federal funds rate by a quarter of a percentage point at its June 25, 2003 Federal Open Market Committee meeting. The move brought the rate to 1.0%--its lowest level since 1958. In explaining the move, the Fed cited that the economy had yet to exhibit sustainable growth, and that "a slightly more expansive monetary policy would add further support for an economy which it expects to improve over time." Q. HOW WERE THE FUNDS MANAGED IN THIS TURBULENT ENVIRONMENT? A. In terms of investment strategies, the funds continued to utilize a "barbell" strategy, whereby we purchased securities at both ends of the maturity spectrum. The funds' longer-term securities--with maturities up to around one year--were used to lock in higher yields as interest rates fell. At the same time, their shorter-term securities--typically one month or less in duration--provided liquidity. 2 <Page> With the combination of a weak economy, uncertainty regarding the outcome and repercussions of the war in Iraq, and corporate accounting scandals, the credit markets were extremely volatile during the period. Therefore, within both UBS RMA Money Market Portfolio and UBS RMA U.S. Government Portfolio, we emphasized US government securities that offered the highest credit quality and liquidity. As such, we were able to avoid the problems that plagued some areas of the corporate credit markets. Within UBS RMA Tax-Free Fund Inc., UBS RMA California Municipal Money Fund, UBS RMA New York Municipal Money Fund, and UBS RMA New Jersey Municipal Money Fund, we also emphasized credit quality and liquidity, which enabled us to avoid the credit problems and downgrades that occurred in the municipal market. Q. WHAT IS YOUR OUTLOOK FOR THE ECONOMY, AND HOW DO YOU ANTICIPATE STRUCTURING THE PORTFOLIO GOING FORWARD? A. In our last report to shareholders, we stated that we were skeptical about the strength of an economic recovery. This proved to be well-founded, as there have been few indications that a sustained economic upturn is taking place. Despite the rapid conclusion to the war in Iraq, there continues to be a great deal of uncertainty around the world. The repercussions of the war remain unknown and the situation in North Korea remains volatile. In the US, one could look at the economic "glass" as either being half full, or half empty. Among the positives, major combat in Iraq has ended and consumer confidence has risen since the height of the war. Oil prices have fallen sharply, and low interest rates continue to spur mortgage refinancing, which places more money in consumers' pockets. The stock market has rallied, and an economic stimulus package was approved by Congress. On the other hand, unemployment remains high, and the economy will have to gain momentum in order to stimulate the labor market. The housing market may have peaked, and consumer debt levels are high. Finally, the Fed has less mobility to lower short-term interest rates--although Chairman Greenspan has indicated his willingness to lower rates again if the economy fails to recover as anticipated. Against this backdrop, credit quality and liquidity will continue to be of paramount importance. To this end, specifically to UBS RMA Money Market Portfolio and UBS RMA U.S. Government Portfolio, we intend to keep a large portion of each Portfolio allocated to US government securities. For all Funds and Portfolios, we expect to continue employing a barbell strategy for as long as spreads between short-term instruments and one-year maturities continue to support such a strategy. 3 <Page> As always, our ultimate objective in managing your investments is to help you successfully meet your financial goals.

------------------------------------------------------------------------------------------- </Table> See accompanying notes to financial statements 62 <Page> UBS RMA Notes to Financial Statements ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES UBS RMA Money Fund Inc. (the "Corporation") and UBS RMA Tax-Free Fund Inc. ("RMA Tax-Free") were organized under the laws of Maryland on July 2, 1982 and are registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended, as open-end management investment companies. RMA Tax-Free is a diversified mutual fund and the Corporation is a series mutual fund with three portfolios, each of which are diversified series: UBS RMA Money Market Portfolio ("Money Market Portfolio"), UBS RMA U.S. Government Portfolio ("U.S. Government Portfolio") and UBS Retirement Money Fund. The financial statements of UBS Retirement Money Fund are not included herein. UBS Managed Municipal Trust ("Managed Municipal Trust") and UBS Municipal Money Market Series ("Municipal Money Market Series") 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 non-diversified series: UBS RMA California Municipal Money Fund ("RMA California") and UBS RMA New York Municipal Money Fund ("RMA New York"). Municipal Money Market Series currently offers one non-diversified series: UBS RMA New Jersey Municipal Money Fund ("RMA New Jersey", and when referred together with Money Market Portfolio, U.S. Government Portfolio, RMA Tax-Free, RMA California and RMA New York collectively, the "Funds"). The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires the Funds' management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. The 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. REPURCHASE AGREEMENTS--The Money Market Portfolio and U.S. Government Portfolio may purchase securities or other obligations from a bank or securities dealer (or its affiliate), subject to the seller's agreement to repurchase them at an agreed upon date (or upon demand) and price. The Money Market Portfolio and U.S. Government Portfolio maintain custody of the underlying obligations prior to their repurchase, either through their regular custodian or through a special "tri-party" custodian or sub-custodian that maintains a separate account for both 63 <Page> the Money Market Portfolio and U.S. Government Portfolio and its counterparty. The underlying collateral is valued daily on a mark-to-market basis to ensure that the value, including accrued interest, is at least equal to the repurchase price. In the event of default of the obligations to repurchase, the Money Market Portfolio and U.S. Government Portfolio generally have the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Repurchase agreements involving obligations other than U.S government securities (such as commercial paper, corporate bonds and mortgage loans) may be subject to special risks and may not have the benefit of certain protections in the event of the counterparty's insolvency. If the seller (or seller's guarantor, if any) becomes insolvent, the Money Market Portfolio and U.S. Government Portfolio may suffer delays, costs and possible losses in connection with the disposition or retention of the collateral. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. The Money Market Portfolio and U.S. Government Portfolio occasionally participate in joint repurchase agreement transactions with other funds managed, advised or sub-advised by UBS Global Asset Management (US) Inc. ("UBS Global AM"). UBS Global AM is an indirect wholly owned asset management subsidiary of UBS AG, an internationally diversified organization with headquarters in Zurich, Switzerland and operations in many areas of the financial services industry. 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 accounting principles generally accepted in the United States. 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 The ability of the issuers of the debt securities held by the Funds to meet their obligations may be affected by economic developments, including those particular to a specific industry or region. Additionally, RMA California, RMA New York and RMA New Jersey follow an investment policy of investing primarily in municipal obligations of one state. Economic changes affecting each state and certain of their public bodies and municipalities may affect the ability of issuers within each state to pay interest on, or repay principal of, municipal obligations held by each of those Funds. 64 <Page> INVESTMENT ADVISOR AND ADMINISTRATOR Each Fund has entered into a board approved Investment Advisory and Administration Contract ("Advisory Contract") with UBS Financial Services Inc., an indirect wholly owned subsidiary of UBS AG, under which UBS Financial Services Inc. serves as investment advisor and administrator of the Funds. In accordance with the Advisory Contract, each Fund pays UBS Financial Services Inc. an investment advisory and administration fee, which is accrued daily and paid monthly, in accordance with the following schedule: <Table> <Caption> AVERAGE DAILY NET ASSETS ANNUAL RATE - ------------------------------------------------------------------------- MONEY MARKET PORTFOLIO AND RMA NEW JERSEY: All 0.50%* U.S. GOVERNMENT PORTFOLIO, RMA CALIFORNIA AND RMA NEW YORK: Up to $300 million 0.50 In excess of $300 million up to $750 million 0.44 Over $750 million 0.36 RMA TAX-FREE: Up to $1.0 billion 0.50 In excess of $1.0 billion up to $1.5 billion 0.44 Over $1.5 billion 0.36 - ------------------------------------------------------------------------- </Table> At June 30, 2003, the Funds owed UBS Financial Services Inc. for investment advisory and administration fees as follows: <Table> Money Market Portfolio $ 9,138,528 U.S. Government Portfolio 825,493 RMA Tax-Free 1,131,186 RMA California 291,454 RMA New York 228,435 RMA New Jersey 68,988 - ------------------------------------------------------------------------- </Table> UBS Global AM serves as sub-advisor and sub-administrator to the Funds pursuant to Sub-Advisory and Sub-Administration Contracts between UBS Financial Services Inc. and UBS Global AM (each a "Sub-Advisory Contract"). In accordance with each Sub-Advisory Contract, UBS Financial Services Inc. (not the Funds) pays UBS Global AM a fee, accrued daily and paid monthly, at an annual rate of 20% of the fee paid by the Funds to UBS Financial Services Inc. under the Advisory Contract. - ---------- * Effective August 29, 2003, fee schedule for RMA New Jersey will change to match that indicated for U.S. Government Portfolio, RMA California and RMA New York. 65 <Page> DISTRIBUTION PLAN UBS Global AM is the principal underwriter of each Fund's shares. Under the plans of distribution, U.S. Government Portfolio, RMA Tax-Free, RMA California and RMA New York are authorized to pay UBS Global AM a monthly service fee at the annual rate of up to 0.15% of average daily net assets and RMA New Jersey is authorized to pay at the annual rate of up to 0.12% of average daily net assets for providing certain shareholder services. Currently, UBS Global AM is compensated for providing such services at the annual rate of 0.125% for each of those Funds except for RMA New Jersey, which pays at the annual rate of 0.12%. No such fees are charged by UBS Global AM for the similar services it provides for the Money Market Portfolio. At June 30, 2003, the Funds owed UBS Global AM for such service fees as follows: <Table> U.S. Government Portfolio $ 264,369 RMA Tax-Free 341,403 RMA California 78,939 RMA New York 60,693 RMA New Jersey 16,557 - ------------------------------------------------------------------------------- </Table> SECURITIES LENDING Each Fund may lend securities up to 33 1/3% of its total assets to qualified broker-dealers or institutional investors. The loans are secured at all times by cash, cash equivalents or U.S. government securities in an amount at least equal to the market value of the securities loaned, plus accrued interest and dividends, determined on a daily basis and adjusted accordingly. Each Fund will regain ownership of loaned securities to exercise certain beneficial rights; however, each Fund may bear the risk of delay in recovery of, or even loss of rights in, the securities loaned should the borrower fail financially. Each Fund receives compensation, which is included in interest income, for lending its securities from interest or dividends earned on the cash, cash equivalents or U.S. Government securities held as collateral, net of fee rebates paid to the borrower plus reasonable administrative and custody fees. UBS Financial Services Inc. and other affiliated broker-dealers have been approved as borrowers under the Funds' securities lending program. For the year ended June 30, 2003, the Money Market Portfolio and the U.S. Government Portfolio earned $1,194,627 and $240,106, respectively, for lending securities. Each Fund's lending agent was UBS Securities LLC (or UBS Financial Services Inc., which provided such service prior to UBS Securities LLC). UBS Securities LLC (or UBS Financial Services Inc.) earned $401,217 and $80,723 in compensation from the Money Market Portfolio and the U.S. Government Portfolio, respectively, for the year ended June 30, 2003. At June 30, 2003, the Money Market Portfolio and the U.S. Government Portfolio owed UBS Securities LLC $24,661 and $8,882, respectively, in compensation. 66 <Page> At June 30, 2003, the Money Market Portfolio and the U.S. Government Portfolio had securities on loan having a market value of $1,476,692,220 and $185,126,270, respectively. The custodian for Money Market Portfolio and U.S. Government Portfolio held cash and cash equivalents as collateral for securities loaned of $1,442,748,674 and $190,630,137, respectively. In addition, Money Market Portfolio's custodian held U.S. Government securities having an aggregate value of $66,279,659 as collateral for portfolio securities loaned as follows: <Table> <Caption> PRINCIPAL AMOUNT MATURITY INTEREST (000) DATES RATES VALUE ---------------------------------------------------------------------------------- $14,500 Federal Home Loan Bank 06/28/04 4.750% $ 15,029,453 51,000 Federal National Mortgage Association 12/04/06 2.200 51,250,206 $ 66,279,659 - --------------------------------------------------------------------------------- </Table> TRANSFER AGENCY AND RELATED SERVICES FEES UBS Global AM provides transfer agency related services to the Funds pursuant to a delegation of authority from PFPC Inc. ("PFPC"), the Funds' transfer agent, and is compensated for these services by PFPC, not the Funds. For the year ended June 30, 2003, UBS Global AM (or UBS Financial Services Inc., which provided such services prior to UBS Global AM) received an approximate percentage of the total transfer agency and related services fees paid by a Fund to PFPC from PFPC, not the Funds, as follows: <Table> Money Market Portfolio 56% U.S. Government Portfolio 58% RMA Tax-Free 54% RMA California 55% RMA New York 60% RMA New Jersey 60% - --------------------------------------------------------------------------------- </Table> OTHER LIABILITIES At June 30, 2003, the Funds had the following liabilities outstanding: <Table> <Caption> PAYABLE FOR DIVIDENDS INVESTMENTS OTHER ACCRUED PAYABLE PURCHASED EXPENSES* - --------------------------------------------------------------------------------- Money Market Portfolio $ 2,315,702 $ 67,902,627 $ 3,830,018 U.S. Government Portfolio 281,132 -- 230,046 RMA Tax-Free 244,755 138,123,532 352,208 RMA California 57,217 65,817,458 95,091 RMA New York 40,046 30,243,953 73,226 RMA New Jersey 7,347 -- 34,573 - --------------------------------------------------------------------------------- </Table> * Excludes investment advisory and administration fees, service fees and payable for securities lending collateral where applicable. 67 <Page> MONEY MARKET FUND INSURANCE BONDS At June 30, 2003, each Fund (except U.S. Government Portfolio) had the ability to use insurance bonds that provided limited coverage for certain loss events involving certain money market instruments held by each of these Funds. These loss events include non-payment of principal or interest or a bankruptcy or insolvency of the issuer or credit enhancement provider (if any). The insurance bonds provided for coverage up to $200 million for a number of funds with a deductible of 30 basis points (0.30%) of the total assets of each Fund for First Tier Securities, determined as of the close of business on the first business day prior to the loss event. In the event of a loss covered under the insurance bonds, each Fund would have expected to retain the security in its portfolio, rather than having to sell it at its current market value, until the date of payment of the loss, which would generally be no later than the maturity of the security. While the insurance bonds were intended to provide some protection against credit risk and to help each Fund maintain a constant price per share of $1.00, there was no guarantee that the insurance bonds would have done so. For the year ended June 30, 2003, the Funds did not use these insurance bonds. FEDERAL TAX STATUS Each Fund intends to distribute all of its 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 their net investment income, realized capital gains and certain other amounts, if any, the Funds intend not to be subject to federal excise tax. At June 30, 2003, the components of accumulated earnings on a tax basis were as follows: <Table> <Caption> ACCUMULATED TOTAL TAX BASIS ORDINARY TAX-EXEMPT CAPITAL AND ACCUMULATED INCOME INCOME OTHER LOSSES EARNINGS - ------------------------------------------------------------------------------------------------------------- Money Market Portfolio $ 7,693,561 -- -- $ 7,693,561 U.S. Government Portfolio 364,277 -- $ (66,251) 298,026 RMA Tax-Free -- $ 244,755 (841) 243,914 RMA California -- 80,772 (23,373) 57,399 RMA New York -- 71,216 -- 71,216 RMA New Jersey -- 11,697 (30) 11,667 </Table> 68 <Page> The tax character of distributions paid to shareholders by the Money Market Portfolio and U.S. Government Portfolio during the fiscal years ended June 30, 2003 and June 30, 2002 was ordinary income. The tax character of distributions paid to shareholders by RMA Tax-Free, RMA California, RMA New York and RMA New Jersey during the fiscal years ended June 30, 2003 and June 30, 2002 was tax-exempt income. At June 30, 2003, the following Funds had net capital loss carryforwards available as reductions, to the extent provided in the regulations, of future net realized capital gains. These losses expire as follows: <Table> <Caption> FISCAL YEAR U.S. RMA RMA ENDING GOVERNMENT PORTFOLIO TAX-FREE RMA CALIFORNIA NEW JERSEY - -------------------------------------------------------------------------------- 2004 -- $ 108 $ 23,373 -- 2011 $ 66,251 733 -- $ 30 $ 66,251 $ 841 $ 23,373 $ 30 </Table> BANK LINE OF CREDIT RMA Tax-Free participated with other funds managed, advised or sub-advised by UBS Global AM in a $300 million committed credit facility ("Facility") with UBS AG, Stamford Branch, to be utilized for temporary financing until the settlement of sales or purchases of portfolio securities, the repurchase or redemption of shares of RMA Tax-Free at the request of the shareholders and other temporary or emergency purposes. Under the Facility arrangement, RMA Tax-Free has agreed to pay a commitment fee, pro rata, based on the relative asset size of the funds in the Facility. Interest was charged to RMA Tax-Free at rates based on prevailing market rates in effect at the time of borrowings. For the year ended June 30, 2003, RMA Tax-Free had an average daily amount of borrowing outstanding under the Facility of $38,788,750 for four days with a related weighted average annualized interest rate of 1.76%, which resulted in $7,077 of interest expense. For the year ended June 30, 2003, RMA Tax-Free paid a commitment fee of $46,786 to UBS AG. At June 30, 2003, there were no outstanding borrowings under the Facility.
