Dear shareholder,

We present you with the annual report for UBS RMA Money Market Portfolio; UBS RMA U.S. Government Portfolio; 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, for the twelve months ended June 30, 2008.

Performance

In an attempt to boost a weakening US economy, the Federal Reserve Board lowered the federal funds rate seven times during the reporting period. (The federal funds rate, or “fed funds” rate, is the rate that banks charge one another for funds they borrow on an overnight basis.) These decreases caused the yields of the securities in which the Funds invest to decline, lowering the Funds’ yields.

As of June 30, 2008, the Funds’ seven-day current yields were:

• UBS RMA Money Market Portfolio: 2.07%, versus 4.76% on June 30, 2007;

• UBS RMA U.S. Government Portfolio: 1.44%, versus 4.36% on June 30, 2007;

* Note: A management change occurred during the reporting period. On March 20, 2008, Robert Sabatino, an executive director in UBS Global Asset Management (Americas) Inc.’s short duration fixed income group, assumed primary responsibility for the UBS RMA Money Market Portfolio and the UBS RMA U.S. Government Portfolio, replacing Michael Markowitz.

An interview with the Portfolio Managers

Q. Can you describe the economic environment during the reporting period?

A: The US economy, which had been fairly resilient through the third quarter of 2007, weakened

considerably during the remainder of the 12-month period. After reporting that second and third quarter 2007 gross domestic product (“GDP”) growth was 3.8% and 4.9%, respectively, the US Department of Commerce said that GDP growth sunk to just 0.6% in the fourth quarter of 2007.

A variety of factors caused the economy to stumble, including the ongoing troubles in the housing market and tepid consumer and

business spending. While there were fears that the economy would contract, GDP grew 0.9% during the first quarter of 2008, and an estimated 1.9% in the second quarter of 2008. This was due, in part, to strong exports, buoyed by a declining dollar that made US goods more attractive overseas.

While the US may not officially be in a recession (defined by two consecutive quarters or more of negative GDP growth), there are numerous strains that may impede a meaningful economic rebound in the near future. Housing prices continue to fall, and credit conditions remain tight due to massive write-downs associated with subprime mortgages.

While the job market had held up relatively well in 2007, it too has faltered. The US Labor Department announced that payrolls fell in each of the first six months of 2008 and the unemployment rate reached

5.7% in July, its highest level since March 2004. Despite slowing growth, inflationary pressures are mounting. Typically, when economic growth slows, falling demand helps to temper rising prices. However, record high oil and rising food prices have caused inflation to remain elevated.

Q. How did the Federal Reserve Board (the “Fed”) react in this economic environment?

A. The Fed has been aggressive in attempting to stabilize the markets and keep the US economy from falling into a recession. As the problems and fallout from subprime mortgages and other issues escalated, the Fed moved into action by pumping substantial amounts of liquidity into the financial system in order to facilitate normal market operations.

In September 2007, the Fed began its campaign of lowering the fed funds rate. From that time through April 2008, the Fed lowered the rate a total of seven times, bringing it to 2.00%, its lowest level since 2004. However, with inflationary pressures mounting, the Fed held the rate steady during its meeting in June 2008.

In its statement accompanying its August 2008 meeting, following the conclusion of the reporting period, the Fed stated: “Economic activity expanded in the second quarter, partly reflecting growth in consumer spending and exports. However, labor markets have softened further and financial markets remain under considerable stress. Tight credit conditions, the ongoing housing contraction, and elevated energy prices are likely to weigh on economic growth over the next few quarters.”

Q. How was the UBS RMA Money Market Portfolio managed during the period?

A. A significant portion of the Portfolio was comprised of commercial paper and short-term corporate obligations during the first half of the reporting period.

Our process led us to be highly selective in terms of the types of commercial paper held in the Portfolio, which benefited performance. (Commercial paper is a short-term security often backed by a guarantee or a letter of credit from a bank or other entity.) During the reporting period, we did not have any positions in single-seller commercial paper conduits or asset-backed commercial paper programs solely backed by mortgages. Instead, we emphasized the more stable multi-seller commercial paper programs. The Portfolio also invested in other types of short-term obligations, including certificates of deposit, during this time.

Toward the middle of the reporting period, we increased the Portfolio’s exposure to repurchase agreements significantly as we sought to increase the Portfolio’s liquidity. (Repurchase agreements are essentially contracts in which the seller of a security agrees to buy it back at a predetermined price and time or upon demand.) This increase helped to reduce the Fund’s risk exposure.

In response to turmoil in certain parts of the asset-backed commercial paper market during the middle of the reporting period, we decreased our exposure to these securities and increased our exposure to US government and agency obligations, benefiting performance. In the Portfolio’s remaining asset-backed commercial paper holdings, we took a cautious approach and emphasized multi-seller conduits and holdings with shorter maturities.

Q. How was the UBS RMA U.S. Government Portfolio managed during the period?

A. Throughout the period, the Portfolio continued to emphasize investments in repurchase agreements backed by government obligations. These investments offered higher yields than direct investments in Treasury securities. Toward the end of the reporting period, we also purchased securities issued by US government agencies in an effort to add yield to the Portfolio, which benefited performance. In doing so, we decreased our exposure to repurchase agreements.

Q. How were the RMA Tax-Free, RMA California, RMA New York and RMA New Jersey Funds managed during the period?

A. We allowed most of the Funds’ weighted average maturities to decrease somewhat as the period progressed, as we believed that interest rates were likely to decrease.

Throughout the reporting period, in order to add yield and diversity to the portfolios, we maintained an exposure to a range of tax-free money market instruments. We focused on uninsured variable rate demand notes, or “VRDNs,” which offered diversification and attractive rates throughout the period.⁽¹⁾ During this time, we also maintained positions in tender option bonds, which benefited performance.⁽²⁾

⁽¹⁾ Purchased at par, VRDNs pay monthly or quarterly interest based on a floating rate that is reset daily or weekly, usually based on an index of short-term municipal rates. The underlying securities or issuers of uninsured VRDNs are deemed to be of high enough quality by themselves, and do not require separate bond insurance to make them eligible investments for money market funds.

⁽²⁾ Securities of this kind are created when a sponsor places long-term municipal bonds in a trust. Next, the structure is further enhanced, usually through the addition of a demand feature of some sort related to notes issued by the trust itself. The trust issues short-term securities and the notes are purchased at par and pay interest periodically based on a floating rate that resets from time to time. We believed many of these programs to be more flexible in adjusting to market challenges.

UBS RMA

As the first half of the reporting period progressed, we purchased tax-exempt commercial paper issued by municipalities, as well as fixed rate notes when attractive issues became available. As a result, the Fund responded well to the credit market volatility that prevailed throughout the reporting period.

In the second half of the reporting period, the Fund continued to invest in uninsured VRDNs, as well as selectively investing in taxable repurchase agreements backed by Treasuries, which benefited performance. (For more information regarding taxable investments, please refer to the box on page 6.) The Fund also continued to invest in tender option bonds.

Q. Municipal bonds have appeared in the headlines in recent months. How did these issues impact the tax-exempt funds?

A. During the reporting period, longer-term municipal bond prices fell dramatically. We believe this was mainly due to issues related to bond insurers, together with forced selling by highly leveraged hedge funds and concerns that slower growth could impact some issuers’ ability to meet their debt obligations. While the municipal bond market rallied somewhat in March 2008, it underperformed the taxable bond market over the course of the reporting period. Within the municipal bond market, shorter-term securities outperformed their longer-term counterparts, and higher-quality bonds outperformed those of a lower quality, given investors’ increased risk aversion.

Turbulence in the subprime mortgage market and elsewhere began impacting several of the bond insurers that back many variable rate demand notes.⁽³⁾ Several of these insurers were downgraded or placed on “credit watch” by the major rating agencies, including Fitch Ratings, Moody’s Investors Service, and Standard & Poor’s⁽⁴⁾ during the period.

Beginning in the first quarter of 2008, we sought to lessen exposure to securities related to certain of those insurers to the extent that we believed it was practicable and appropriate to do so. Instead, the Funds

focused on maintaining an allocation to two types of higher-quality

issues. These included those backed by bond insurer Financial Security Assurance (FSA), the only insurer to have its AAA rating affirmed, and deemed to have a stable outlook from all three rating agencies, as well as issues in which we deemed the underlying issuers’ credit quality to

⁽³⁾ Bond insurers offer financial guaranty insurance policies, which guarantee that the insurer will make the scheduled principal and interest payments on time and in full if the issuer cannot.

⁽⁴⁾ Examples of more well-known ratings services are Moody’s Investors Service, Standard and Poor’s (a division of The McGraw-Hill Companies) and Fitch Ratings.

Special note regarding the tax-exempt funds:

In response to events in the municipal bond market during the reporting period, many fund managers winnowed their exposures to insured municipal money market issues most vulnerable to downgrades, diminishing the available supply of suitable investment opportunities. In order to pursue competitive yields for investors— while seeking to adhere to high credit-quality constraints—UBS Global Asset Management determined it to be in the best interests of shareholders to make temporary, limited investments of appropriate credit quality within the taxable securities universe, to the extent allowable by the Funds’ offering documents and as believed prudent or appropriate. While our primary focus was on investing in municipal securities, given the challenging conditions and our emphasis on safety, these taxable investments were made for a limited period of time during the second half of the reporting period, and represented a small percentage of the funds’ portfolios.

While the Funds benefited from their investments in taxable securities, a portion of the Funds’ yields may not be as tax advantaged as ordinary municipal money market investments. However, we think that the higher yield paid on the taxable investments should at least partially offset any lost tax advantage. In addition, due to a lack of availability of state-specific municipal investments meeting our investment criteria, the California, New Jersey, and New York municipal funds purchased limited quantities of out-of-state municipal bonds at times during the reporting period, which also had a slight impact on the tax advantages of affected funds. Of course, we plan to continue to manage the Funds so that the tax characteristics of the underlying securities are passed through to the shareholders to the extent allowed.

be sufficient, even without any insurance overlay. The tax-exempt funds placed greater emphasis on these types of issues. We conduct careful analysis on the credit quality of the underlying issuer of securities, regardless of the existence of the insurance enhancement. The municipal issuers underlying our insured positions are primarily within a range that is higher than the average quality of the overall insured market, as measured by the Lehman Brothers Municipal Bond Index.

Q. What factors do you believe will affect the portfolios over the coming months?

A. Recent economic data suggest that the US economy may be headed for further contraction. As the financial markets continue to be plagued by low liquidity, further write-downs at major investment banks appear likely. We believe that the Fed will remain concerned about inflationary

pressures on the economy, and that inflation considerations will weigh on their decisions regarding the fed funds rate in the coming quarters. In response to the market conditions, we plan to continue to monitor economic data closely and actively manage the Funds’ portfolios as we seek to add value for our shareholders.

⁽¹⁾ Security exempt from registration under Rule 144A of the Securities Act of 1933. These securities, which represent 16.68% of net assets as of June 30, 2008, are considered liquid and may be resold in transactions exempt from registration, normally to qualified institutional buyers.

⁽²⁾ The Fund does not directly own the municipal security indicated; the Fund owns an interest in a special purpose entity that, in turn, owns the underlying municipal security. The special purpose entity permits the Fund to own interests in underlying assets, but in a manner structured to provide certain advantages not inherent in the underlying bonds (e.g., enhanced liquidity, yields linked to short-term rates).

⁽³⁾ Security subject to Alternative Minimum Tax.

⁽⁴⁾ Security purchased on a when-issued basis. When issued refers to a transaction made conditionally because a security, although authorized, has not yet been issued.

⁽⁵⁾ Zero coupon bond; interest rate represents annualized yield at date of purchase.

⁽⁶⁾ Rates shown reflect yields at June 30, 2008.

Statement of net assets—June 30, 2008

⁽¹⁾ Securities subject to Alternative Minimum Tax.

⁽²⁾ The fund does not directly own the municipal security indicated; the Fund owns an interest in a special purpose entity that, in turn, owns the underlying municipal security. The special purpose entity permits the Fund to own interests in underlying assets, but in a manner structured to provide certain advantages not inherent in the underlying bonds (e.g., enhanced liquidity, yields linked to short-term rates).

⁽³⁾ Security exempt from registration under Rule 144A of the Securities Act of 1933. These securities, which represent 12.22% of net assets as of June 30, 2008, are considered liquid and may be resold in transactions exempt from registration, normally to qualified institutional buyers.

⁽⁴⁾ Rate shown reflects yield at June 30, 2008.

Understanding your funds’ expenses (unaudited)

As a shareholder of the Funds*, you incur ongoing costs, including management fees, service fees (12b-1 or non-12b-1 fees) and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in each Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The examples below are based on an investment of $1,000 invested at the beginning of the period and held for the entire period, January 1, 2008 to June 30, 2008.

Actual expenses

The first line in the following table for each Fund provides information about its actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over a period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line for each respective Fund 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 second line in the following table for each Fund provides information about hypothetical account values and hypothetical expenses based on that Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not that 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 a Fund and other funds.

To do so, compare these 5% hypothetical examples with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs. Therefore, the second line of the table for each Fund is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds, if those funds impose transactional costs—for example, exchange fees. In addition, if those transactional costs were included, your costs for those other funds would have been higher.

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 and currently has 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”.

Each Trust or Corporation accounts separately for the assets, liabilities and operations of each series. Expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to all series are allocated among them on a pro rata basis.

In the normal course of business the Funds may enter into contracts that contain a variety of representations or that provide indemnification for certain liabilities. The Funds’ maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote.

Notes to financial statements

The preparation of financial statements in accordance with US generally accepted accounting principles 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, unless the Fund’s Board of Directors/Trustees (the “Board”) determines that this does not represent fair value. Periodic review and monitoring of the valuation of the securities held by the Funds is performed in an effort to ensure that amortized cost 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.

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. As of June 30, 2008, management does not believe the adoption of FAS 157 will impact the amounts reported in the financial statements, however, additional disclosures will be required about the inputs used to develop the measurements of fair value and the effect of certain measurements reported on the Statement of operations for a fiscal period.

Repurchase agreements—Each Fund 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. Each Fund maintains custody of the underlying obligations prior to their repurchase, either through its regular custodian or through a special “tri-party” custodian or sub-custodian that maintains a separate account for both the Funds and their counterparty. The underlying collateral is valued daily to ensure that the value, including accrued interest, is at least equal to the repurchase price. In the event of

111

UBS RMA

Notes to financial statements

default of the obligation to repurchase, the Funds generally have the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Repurchase agreements involving obligations other than US 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 counterparty insolvency. If the seller (or seller’s guarantor, if any) becomes insolvent, a Fund 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. Each Fund may participate in joint repurchase agreement transactions with other funds managed, advised or sub-advised by UBS Global Asset Management (Americas) Inc. (“UBS Global AM”). Money Market Portfolio and U.S. Government Portfolio may engage in repurchase agreements as part of normal investing strategies; the other Funds generally would only engage in repurchase agreement transactions as temporary or defensive 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 US 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

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, country 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 under normal market conditions. Economic changes affecting each state and certain of its 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.

Notes to financial statements

Investment advisor and administrator

Each Fund’s Board has approved an investment advisory and administration contract (“Advisory Contract”) for each Fund 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 schedules:

Average daily net assets	Annual rate
Money Market Portfolio:
All	0.50	%†

† UBS Financial Services Inc. has agreed to waive portions of its investment advisory and administration fee for the Money Market Portfolio (the “Portfolio”) so that the fee rate is reduced to the following: up to $1.0 billion in average daily net assets—0.50%; in excess of $1.0 billion up to $1.5 billion in average daily net assets—0.44%; and over $1.5 billion in average daily net assets—0.36%. UBS Financial Services Inc. has further agreed to cap the Portfolio’s aggregate management and shareholder services fees (paid pursuant to the Portfolio’s Shareholder Services Plan) so that the total of these does not exceed 0.50% of the Portfolio’s average daily net assets. This cap results in an effective investment advisory and administration fee rate not to exceed 0.375% of the Portfolio’s average daily net assets. (UBS Financial Services Inc. is waiving a portion of its advisory and administration fees to offset the shareholder services fees, and this waiver continues for as long as the Portfolio’s Shareholder Services Plan remains in effect). Accordingly, for the year ended June 30, 2008, UBS Financial Services Inc. waived $19,917,848 of its investment advisory and administration fees from the Portfolio. At June 30, 2008, UBS Financial Services Inc. owed the Portfolio $1,794,054 for fee waivers under the above agreement.

Average daily net assets	Annual rate
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	%
RMA New Jersey:
Up to $300 million	0.45	%
In excess of $300 million up to $750 million	0.39	%
Over $750 million	0.31	%

UBS RMA

Notes to financial statements

At June 30, 2008, the Funds owed UBS Financial Services Inc. for investment advisory and administration fees as follows:

Money Market Portfolio	$6,934,271
U.S. Government Portfolio	788,794
RMA Tax-Free	2,438,980
RMA California	610,273
RMA New York	516,074
RMA New Jersey	129,174

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 0.08% of the respective Fund’s average daily net assets.

Reimbursement for postage related charges from affiliate—Each Fund was reimbursed by UBS Financial Services Inc. in the amounts indicated below for overcharges related to prior fiscal periods for postage related expenses:

Money Market Portfolio	$877,352
U.S. Government Portfolio	29,175
RMA Tax-Free	49,815
RMA California	11,143
RMA New York	9,385
RMA New Jersey	2,454

Additional information regarding compensation to affiliate of a board member

Effective March 1, 2005, Professor Meyer Feldberg accepted the position of senior advisor to Morgan Stanley, resulting in him becoming an interested board member of the Funds. The Funds have been informed that Professor Feldberg’s role at Morgan Stanley does not involve matters directly affecting any UBS funds. Fund transactions are executed through Morgan Stanley based on that firm’s ability to provide best execution of the transactions. During the year ended June 30, 2008, the Funds

114

UBS RMA

Notes to financial statements

purchased and sold certain securities (e.g., fixed income securities) in principal trades with Morgan Stanley having aggregate values as follows:

Money Market Portfolio	$10,091,388,844
U.S. Government Portfolio	47,199,063,900
RMA Tax-Free	3,295,332,500
RMA California	1,054,598,200
RMA New York	694,116,847
RMA New Jersey	165,709,500

Morgan Stanley received compensation in connection with these trades, which may have been in the form of a “mark-up” or “mark-down” of the price of the securities, a fee from the issuer for maintaining a commercial paper program, or some other form of compensation. Although the precise amount of this compensation is not generally known by the Fund’s investment advisor or sub-advisor, it is believed that under normal circumstances such compensation represents a small portion of the total value of the transactions.

Shareholder service plans

UBS Global Asset Management (US) Inc. (“UBS Global AM (US)”) is the principal underwriter of each Fund’s shares and has appointed UBS Financial Services Inc. as a dealer for the sale of the Funds’ shares. Under the shareholder service plans, Money Market Portfolio, U.S. Government Portfolio, RMA Tax-Free, RMA California and RMA New York pay UBS Global AM (US) a monthly service fee, which is accrued daily and paid monthly at an 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 (US) is compensated for providing such services at the annual rate of 0.125% of the Fund’s average daily net assets for each of those Funds except for RMA New Jersey, which pays at the annual rate of 0.12% of the Fund’s average daily net assets. At June 30, 2008, the Funds owed UBS Global AM (US) for such service fees as follows:

Money Market Portfolio	$1,733,568
U.S. Government Portfolio	251,688
RMA Tax-Free	795,639
RMA California	189,701
RMA New York	157,048
RMA New Jersey	35,208

Transfer agency related services fees

UBS Financial Services Inc. provides certain services pursuant to a delegation of authority from PNC Global Investment Servicing (“PNC”), the Funds’ transfer agent, and is compensated for these services by PNC, not the Funds.

For the year ended June 30, 2008, UBS Financial Services Inc. received from PNC, not the Funds, total transfer agency related services fees as follows:

Money Market Portfolio	$4,112,354
U.S. Government Portfolio	195,602
RMA Tax-Free	1,325,276
RMA California	226,493
RMA New York	193,388
RMA New Jersey	64,899

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, US government securities or irrevocable letters of credit 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 for lending its securities from interest or dividends earned on the cash, US government securities or irrevocable letters of credit 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. UBS Securities LLC is the lending agent for each Fund. For the year ended June 30, 2008, UBS Securities LLC earned $1,599,464 and $147,550 in compensation from the Money Market Portfolio and the U.S. Government Portfolio, respectively, as the Funds’ lending agent. At June 30, 2008, the Money Market Portfolio and U.S. Government Portfolio owed UBS Securities LLC $67,458 and $66, respectively, in compensation as the Funds’ lending agent. At June 30, 2008, the Money Market Portfolio and U.S. Government Portfolio had securities on loan having a market value of $1,479,386,178 and $39,842,600, respectively. The U.S. Government

Portfolio’s custodian held a US Government security having a value of $41,638,069 as collateral for portfolio securities loaned as follows:

Principal amount (000)		Maturity date	Interest rate		Value
$34,445	US Treasury Inflation Index Bond	01/15/25	2.375	%	$41,638,069

RMA Tax-Free, RMA California, RMA New York and RMA New Jersey did not loan any securities during the year ended June 30, 2008.

Bank line of credit

RMA Tax-Free participates with certain other funds managed, advised or sub-advised by UBS Global AM in a $100 million committed credit facility with State Street Bank and Trust Company (“Committed Credit Facility”), 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 shareholders and other temporary or emergency purposes. Under the Committed Credit Facility arrangement, RMA Tax-Free has agreed to pay commitment fees, pro rata, based on the relative asset size of the funds in the Committed Credit Facility. Interest will be charged to RMA Tax-Free at the overnight federal funds rate in effect at the time of borrowings, plus 0.50%. For the year ended June 30, 2008, RMA Tax-Free had an average daily amount of outstanding borrowing of $9,039,182 for 17 days with a related weighted average annualized interest rate of 4.31%, which resulted in $18,397 of interest expense.

Notes to financial statements

In accordance with US Treasury regulations, RMA New Jersey has elected to defer realized capital losses of $667, arising after October 31, 2007. Such losses are treated for tax purposes as arising on July 1, 2008.

At June 30, 2008, the effect of permanent “book/tax” reclassifications resulted in increases and decreases to components of the Portfolios’ net assets as follows:

	Accumulated undistributed net investment income		Paid in capital
RMA Tax-Free	$	1,852	$	(1,852	)
RMA California		1,399		(1,399	)
RMA New York		250		(250	)
RMA New Jersey		734		(734	)

These differences are due to the tax treatment of nondeductible excise tax payments made during the fiscal year.

The Funds adopted the provisions of Financial Accounting Standards Board Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes. The implementation of FIN 48 resulted in no material liabilities for unrecognized tax benefits and no material changes to the beginning net asset values of the Funds.

As of and during the year ended June 30, 2008, the Funds did not have any liabilities for any unrecognized tax benefits. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statements of operations. During the year ended June 30, 2008, the Funds did not incur any interest or penalties.

Each of the tax years in the four year period ended June 30, 2008, remains subject to examination by the Internal Revenue Service and state taxing authorities. The adoption of FIN 48 had no impact on the operations of the Funds for the year ended June 30, 2008.

We have audited the accompanying statements of net assets of the UBS RMA Money Market Portfolio and UBS RMA U.S. Government Portfolio (two of the series comprising UBS RMA Money Fund Inc.), UBS RMA Tax-Free Fund Inc., UBS RMA California Municipal Money Fund and UBS RMA New York Municipal Money Fund (two of the series comprising UBS Managed Municipal Trust) and UBS RMA New Jersey Municipal Money Fund (the sole series comprising UBS Municipal Money Market Series) (collectively, the “Funds”) as of June 30, 2008, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds’ 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 the standards of the Public Company Accounting Oversight Board (United States). 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. We were not engaged to perform an audit of the Funds’ internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of June 30, 2008, by correspondence with the custodian and others, or by other appropriate auditing procedures where

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of UBS RMA Money Market Portfolio, UBS RMA U.S. Government Portfolio, 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 at June 30, 2008, 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 five years in the period then ended, in conformity with US generally accepted accounting principles.

(e) (1)     Audit Committee Pre-Approval Policies and Procedures:

The registrant’s Audit Committee (“audit committee”) has adopted an “Audit Committee Charter (Amended and Restated as of May 12, 2004 – with revisions through November 6, 2006)” (the “charter”). The charter contains the audit committee’s pre-approval policies and procedures. Reproduced below is an excerpt from the charter regarding pre-approval policies and procedures:

The [audit ]Committee shall:

…

2. Pre-approve (a) all audit and permissible non-audit services¹ to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund’s independent auditors to UBS Global [Asset Management (Americas) Inc. (“UBS Global AM”)] and any Covered Service Providers, if the engagement relates directly to the operations and financial reporting of the Fund. In carrying out this responsibility, the Committee shall seek periodically from UBS Global [AM] and from the independent auditors a list of such audit and permissible non-audit services that can be expected to be rendered to the Fund, UBS Global [AM] or any Covered Service Providers by the Fund’s independent auditors, and an estimate of the fees sought to be paid in connection with such services. The Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to a sub-committee consisting of the Chairperson of the Committee

and two other members of the Committee as the Chairperson, from time to time, may determine and appoint, and such sub-committee shall report to the Committee, at its next regularly scheduled meeting after the sub-committee’s meeting, its decision(s). From year to year, the Committee shall report to the Board whether this system of pre-approval has been effective and efficient or whether this Charter should be amended to allow for pre-approval pursuant to such policies and procedures as the Committee shall approve, including the delegation of some or all of the Committee’s pre-approval responsibilities to other persons (other than UBS Global [AM] or the Fund’s officers).

¹ The Committee will not approve non-audit services that the Committee believes may taint the independence of the auditors. Currently, permissible non-audit services include any professional services (including tax services) that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, UBS Global [AM] and any service providers controlling, controlled by or under common control with UBS Global [AM] that provide ongoing services to the Fund (“Covered Service Providers”) constitutes not more than 5% of the total amount of revenues paid to the independent auditors (during the fiscal year in which the permissible non-audit services are provided) by (a) the Fund, (b) its investment adviser and (c) any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(e) (2)     Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

There were no amounts that were approved by the audit committee pursuant to the de minimis exception for the fiscal years ended June 30, 2008 and June 30, 2007 on behalf of the registrant.

There were no amounts that were required to be approved by the audit committee pursuant to the de minimis exception for the fiscal years ended June 30, 2008 and June 30, 2007 on behalf of the registrant’s service providers that relate directly to the operations and financial reporting of the registrant.

All Other Fees:

(f) According to E&Y, for the fiscal year ended June 30, 2008, the percentage of hours spent on the audit of the registrant’s financial statements for the most recent fiscal year that were attributed to work performed by persons who are not full-time, permanent employees of E&Y was 0%.

(g) For the fiscal years ended June 30, 2008 and June 30, 2007, the aggregate fees billed by E&Y of $1,536,448 and $1,491,995, respectively, for non-audit services rendered on behalf of the registrant (“covered”), its investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) and any entity controlling, controlled by, or under common control with the adviser (“non-covered”) that provides ongoing services to the registrant for each of the last two fiscal years of the registrant is shown in the table below:

	2008		2007
Covered Services	$	11,200	$	15,373
Non-Covered Services		1,525,248		1,476,622

(h) The registrant’s audit committee was not required to consider whether the provision of non-audit services that were rendered to the registrant’s investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under

common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.
