August 17, 2010

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; UBS RMA California Municipal Money Fund; UBS RMA New York Municipal Money Fund; and UBS RMA New Jersey Municipal Money Fund, for the 12 months ended June 30, 2010. Performance Given pockets of weakness in the economy, including continued high unemployment, the Federal Reserve Board (the “Fed”) maintained the federal funds rate at a historically low range of between 0.00% and 0.25% 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.) This caused the yields of the securities in which the Funds invest to remain very low, which, in turn, negatively impacted the Funds’ yields. As of June 30, 2010, after fee waivers/expense reimbursements, the Funds’ seven-day current yields were: • UBS RMA Money Market Portfolio: 0.01%, versus 0.01% on June 30, 2009; •  UBS RMA U.S. Government Portfolio: 0.01%, versus 0.01% on June 30, 2009;

An interview with the Portfolio Managers
Q.	How would you describe the economic environment during the reporting period?
A.	While certain economic data somewhat moderated toward the end of the reporting period, the economy, overall, continued to expand. After four consecutive quarters of declining gross domestic product (“GDP”) growth, the US economy started to expand in the third quarter of 2009 and has continued to expand thus far into 2010. Economic growth was supported by the federal government’s $787 billion stimulus program, increased consumer spending and improved manufacturing activity, as companies moved to rebuild inventories amid rising demand.
Q.	How did the Fed react to the economic environment?
A.	Although the economy continued to expand through the last three quarters of the reporting period, the Fed remained concerned about continued high unemployment, which was an elevated 9.5% in June 2010. As a result, the Fed maintained its highly accommodative monetary policy, keeping the fed funds rate within a range of 0.00% to 0.25%—a historic low. The Fed has now held short-term interest rates steady since December 2008. At its meeting in June 2010, the Fed reasserted the rationale for this policy stating that it “will maintain the target range for the federal funds rate at 0 to 1/4 percent and continues to anticipate that economic conditions, including low rates of resource utilization, subdued inflation trends, and stable inflation

	expectations, are likely to warrant exceptionally low levels of the federal funds rate for an extended period.”
Q.	How was UBS RMA Money Market Portfolio managed during the period?
A.	We sought to maintain a high degree of liquidity in the Fund in order to minimize pricing volatility and to meet redemption requests. When the reporting period began, the Fund’s weighted average maturity (WAM) was 39 days. (Weighted average maturity is an average of the maturity dates of a portfolio’s securities, weighted by the dollar amount that is invested in each maturity.) As the reporting period continued and the credit markets stabilized, we increased the Fund’s weighted average maturity significantly, reaching 46 days on December 31, 2009. During the second half of the reporting period, we reduced the Fund’s weighted average maturity and ended the period at 35 days. This was done in light of new Securities and Exchange Commission (“SEC”) requirements related to money market funds (we provide more information on this development on page 5 of this report). In addition, it was our expectation that interest rates would rise as the Fed began to take steps—ahead of any moves to increase the fed funds rate—to remove current high levels of liquidity from the market.
	At the issuer level, we maintained a greater-than-usual level of diversification over the fiscal year by investing in smaller positions, with the goal of reducing risk and keeping the Fund highly liquid. As the economic environment improved over the period, we gradually increased our single issuer exposure, typically purchasing up to 3.00% in single nongovernment issuers toward the end of the reporting period. The Fund is generally able to hold up to 5.00% in any one issuer (subject to certain exceptions).
	In terms of securities, we increased the Fund’s exposure to commercial paper, US government and agency obligations and certificates of deposit over the 12-month period. In contrast, we decreased the Fund’s exposure to repurchase agreements and short-term corporate obligations. (Repurchase agreements are transactions in which the seller of a security agrees to buy it back at a predetermined time and price or upon demand.)
Q.	How was UBS RMA U.S. Government Portfolio managed during the period?
A.	During the first half of the reporting period, the Fund shifted its emphasis from repurchase agreements backed by US government and agency obligations—which had been offering higher yields than direct

UBS RMA

	investments in Treasury securities—to investments in US government and agency obligations themselves. In doing so, we decreased the Fund’s exposure to repurchase agreements.
	Given changing market conditions, we reversed this stance during the second half of the period. During that time, we significantly increased the Fund’s exposure to repurchase agreements and substantially decreased the Fund’s exposure to US government and agency obligations.
	During the period, the Fund’s weighted average maturity varied somewhat, moving from 38 days at the beginning of the period to 48 days on December 31, 2009. We then reduced the weighted average maturity, ending at 38 days on June 30, 2010.
Q.	How were the RMA Tax-Free, RMA California Municipal, RMA New York Municipal and RMA New Jersey Municipal Money Funds managed during the period?
A.	During much of the reporting period, we maintained a short weighted average maturity for the Funds. Given the flat yield curve that existed for most of the review period, where short- and longer-term yields were relatively similar, we did not believe it was appropriate from a risk/reward perspective to extend the Funds’ maturities.
	That said, we continued to emphasize variable rate demand notes (VRDNs)(1) with yields that reset on a daily or weekly basis. We also looked to enhance the Funds’ credit quality by reducing the Funds’ exposure to certain VRDNs that we believed to have weaker letters of credit (a form of credit enhancement) and liquidity providers. In addition, we purchased tax-exempt commercial paper with 90-day maturities, as we felt they were attractively valued and provided attractive incremental yield potential.
	Toward the end of the reporting period, the development of an upward sloping yield curve allowed us to extend the Funds’ WAMs when we believed appropriate, to potentially pick up additional yield further out on the yield curve. We pared some of the Funds’ exposures to VRDNs and commercial paper, and selectively purchased municipal money market securities with maturities up to one year.

⁽¹⁾ A variable rate demand note is a long-term bond with a floating interest rate that provides investors with the option to tender, or “put” the security at par with seven day’s notice or, in some cases, one day’s notice.

	At the state level, California continued to experience severe budgetary challenges. As a result, in the RMA California Municipal Money Fund, we avoided direct obligations of the state. Rather, we emphasized essential service bonds, which include those issued by water and sewer authorities, as well as certain utilities within California that met our credit criteria. We also diversified the Fund’s holdings by selecting securities from a variety of issuers throughout the state.
	Both New York and New Jersey also grappled with issues related to their state budgets. As was the case in California, we favored essential service revenue bonds. These included water, sewer and select utilities. In New York, we were also drawn to certain securities issued by New York City, as its financial situation was in relatively better shape than the state. In New Jersey, we also favored local municipalities in wealthier areas. As always, we continued to diversify our holdings in both states to mitigate exposure to any single entity.
Q.	What is your outlook for the economy?
A.	We continue to believe that the risks to economic growth and inflation are concentrated primarily in fiscal and monetary policy decisions, including resolution of sovereign debt problems, and the uncertainty surrounding these issues remains exceptionally high. While there remains a view that interest rates will trend higher by mid 2011, the events that occurred toward the end of the reporting period have called into question the magnitude and timing of any increase. The events of recent years warrant continued emphasis on risk management and close attention to all market exposures.
	On a final note, on January 27, 2010, the Securities and Exchange Commission (“SEC”) adopted rule amendments designed to strengthen the regulations governing money market funds. The amendments impose new liquidity, credit quality and maturity limits. They also enhance disclosures by, among other things, requiring the monthly posting of portfolio holdings reports (beginning in October 2010). UBS Global Asset Management (Americas) Inc. (“UBS Global AM”) welcomes the SEC’s approval of these new requirements. We believe that they will fortify the money market sector and are consistent with our long-standing conservative approach to the management of our US money market funds.

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.

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, 2010 to June 30, 2010.

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.

“Actual—Ending account value” may not be reflective of a shareholder’s actual investment experience during periods of very low interest rates. While the Fund declares dividends daily and pays them monthly, the amounts are rounded to the nearest $0.01 on a daily basis with respect to each investor’s account. As a result, investors whose Fund account balances earn daily dividends that total less than one half a cent on any given day will not accrue any dividends on that day.

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 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.

UBS RMA

Notes to financial statements

In June 2009, the Financial Accounting Standards Board (“FASB”) established the FASB Accounting Standards Codification^TM (“Codification”) as the single source of authoritative accounting principles recognized by the FASB in the preparation of financial statements in conformity with US generally accepted accounting principles (“GAAP”). The Codification supersedes existing and nongrandfathered, non-SEC accounting and reporting standards. The Codification did not change GAAP but rather organized it into a hierarchy where all guidance within the Codification carries an equal level of authority. The Codification became effective on July 1, 2009. The Codification did not have a material effect on the Funds’ financial statements.

The preparation of financial statements in accordance with GAAP 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 of investments—Investments are valued at amortized cost. 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.

GAAP requires disclosure surrounding the various inputs that are used in determining the value of the Funds’ investments. These inputs are summarized into the three broad levels listed below:

Level 1—Unadjusted quoted prices in active markets for identical investments.
Level 2—Other significant observable inputs, including but not limited to, quoted prices for similar investments, interest rates, prepayment speeds and credit risks.
Level 3—Unobservable inputs inclusive of the Funds’ own assumptions in determining the fair value of investments.

In accordance with the requirements of GAAP, a fair value hierarchy has been included near the end of each Funds’ Statement of net assets.

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about Fair Value Measurements”. ASU No. 2010-06 requires reporting entities to make new disclosures about amounts and reasons for significant transfers in and out of Level 1 and

98

UBS RMA

Notes to financial statements

Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3, and information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. The new and revised disclosures are required to be implemented for annual and interim periods beginning after December 15, 2009 except for the disclosures surrounding purchases, sales, issuances and settlements on a gross basis in the reconciliation of Level 3 fair value measurements, which are effective for annual and interim periods beginning after December 15, 2010. The Funds adopted the new disclosures during the reporting period and did not have any transfers in and out of Level 1 and Level 2.

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 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.

99

UBS RMA

Notes to financial statements

Under certain circumstances, a Fund may engage in a repurchase agreement transaction with a yield of zero in order to invest cash amounts remaining in its portfolio at the end of the day in order to avoid having the Fund assessed a fee for univested cash held in a business account at a bank.

Investment transactions, investment income and expenses—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. Discounts are accreted and premiums are amortized 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 GAAP. 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 and political 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.

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

Notes to financial statements

is accrued daily and paid monthly, in accordance with the following schedules:

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

^† Effective November 12, 2009, 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%; in excess of $1.5 billion up to $5.0 billion in average daily net assets–0.36%; in excess of $5.0 billion up to $10.0 billion in average daily net assets–0.35%; in excess of $10.0 billion up to $15.0 billion in average daily net assets–0.34%; in excess of $15.0 billion up to $20.0 billion in average daily net assets–0.33%; and over $20.0 billion in average daily net assets–0.30%. Prior to November 12, 2009, UBS Financial Services Inc. had contractually agreed to waive portions of its investment advisory and administration fee for the Portfolio so that the rates were 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%. The waivers effective November 12, 2009, reflect additional breakpoints on fees when assets exceed $5 billion; although these additional breakpoints are not contractual, UBS Financial Services Inc. will not modify or remove the additional breakpoints without consulting with the Portfolio’s board. 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 the cap continues for as long as the Portfolio’s Shareholder Services Plan remains in effect). Accordingly, for the year ended June 30, 2010, UBS Financial Services Inc. waived $20,291,324 of its investment advisory and administration fees from the Portfolio.

Average daily net assets	Annual rate
U.S. Government Portfolio††, RMA California and RMA New York:

Although the additional breakpoints on fees when assets exceed $5 billion are not contractual, UBS Financial Services Inc. will not modify or remove the additional breakpoints without consulting with the boards overseeing U.S. Government Portfolio and RMA Tax-Free.

At June 30, 2010, certain Funds owe (or are owed by) UBS Financial Services Inc. for investment advisory and administration fees, net of fee waivers and/or expense reimbursements, as follows:

Money Market Portfolio	$1,204,818

RMA Tax-Free	405,381
RMA California	39,886
RMA New York	51,790

In addition to the above arrangements, UBS Financial Services Inc. has undertaken to waive fees and/or reimburse expenses in the event that current Fund yields drop below a certain level. This additional undertaking is voluntary and not contractual and may be terminated at any time. For the year ended June 30, 2010, UBS Financial Services Inc. voluntarily waived investment advisory and administration fees and/or reimbursed expenses as follows (these amounts are in addition to the waivers noted above):

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.

Additional information regarding compensation to affiliate of a board member
Professor Meyer Feldberg serves as a senior advisor to Morgan Stanley, a financial services firm with which the Funds may conduct transactions, resulting in him being 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, 2010, the Funds purchased and sold certain securities (e.g., fixed income securities) in principal trades with Morgan Stanley having aggregate values as follows:

Money Market Portfolio	$96,351,214,625
U.S. Government Portfolio	118,945,000,000
RMA Tax-Free	2,594,868,400
RMA California	490,530,000
RMA New York	530,687,000
RMA New Jersey	117,665,000

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 Funds’ 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 Funds’ shares and has appointed UBS Financial Services Inc. as a dealer for the sale of the Funds’ shares. Under

Notes to financial statements

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 Funds’ 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 Funds’ average daily net assets. At June 30, 2010, the Funds owed UBS Global AM (US) for such service fees as follows:

Money Market Portfolio	$1,490,471
U.S. Government Portfolio	387,587
RMA Tax-Free	469,405
RMA California	102,790
RMA New York	92,674
RMA New Jersey	27,004

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

For the year ended June 30, 2010, UBS Financial Services Inc. received from BNY Mellon, not the Funds, total delegated services fees as follows:

Money Market Portfolio	$3,931,512
U.S. Government Portfolio	299,564
RMA Tax-Free	1,030,454
RMA California	181,504
RMA New York	161,109
RMA New Jersey	55,240

Securities lending
Each Portfolio may lend securities up to 33¹/₃% 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

104

Notes to financial statements

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. State Street Bank and Trust Company serves as the Funds’ lending agent. At June 30, 2010, the Funds did not have any securities on loan.

Bank line of credit
RMA Tax-Free, RMA California, RMA New York and RMA New Jersey participate 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 each Fund at the request of shareholders and other temporary or emergency purposes. Under the Committed Credit Facility arrangement, each Fund has agreed to pay commitment fees, pro rata, based on the relative asset size of the funds in the Committed Credit Facility. Interest is charged to each Fund at the prevailing rates in effect at the time of borrowings. For the year ended June 30, 2010, the following Funds had borrowings:

	Average daily		Weighted
	amount of		average
	borrowing	Days	annualized	Interest

RMA Tax-Free	$7,398,468	4	0.942%	$	774

There were no borrowings from the Committed Credit Facility outstanding as of June 30, 2010.

US Treasury Temporary Guarantee Program for Money Market Funds
Each Fund participated in the US Treasury Department Temporary Guarantee Program for Money Market Funds. The program covered shareholders of participating money market funds as of the close of business on September 19, 2008. The program expired on September 18, 2009. Each Fund bore the cost of participating in this program, to the extent not offset by UBS Financial Services Inc.’s fee waivers/voluntary expense reimbursements. Each Fund paid a fee of 0.01% of the value of the Funds’ outstanding shares on September 19, 2008 (valued at $1.00 per share) for participation in the program for the initial coverage period of September 19, 2008, through December 18, 2008. The program was first extended until April 30, 2009, and each Fund paid a fee calculated in the

107

UBS RMA

Notes to financial statements

same manner but at the rate of 0.015% for continued participation in the program through that date. The program was then extended a final time, providing coverage through September 18, 2009. In April, each Fund paid an additional fee for continued coverage for the period May 1, 2009, through September 18, 2009, calculated in the same manner and at the same 0.015% rate as for the initial extension period.

Federal tax status
Each Fund intends to distribute all or substantially 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, net realized capital gains and certain other amounts, if any, the Funds intend not to be subject to a federal excise tax.

The tax character of all distributions paid to shareholders by the Money Market Portfolio and U.S. Government Portfolio during the fiscal years ended June 30, 2010 and June 30, 2009 was ordinary income. The tax character of all distributions paid to shareholders by RMA Tax-Free, RMA California, RMA New York and RMA New Jersey during the fiscal years ended June 30, 2010 and June 30, 2009 were as follows:

For the year ended	RMA		RMA		RMA		RMA

At June 30, 2010, components of accumulated earnings on a tax basis for each of the Funds were as follows:

							Accumulated			Total tax basis
	Ordinary		Tax-exempt		Long-term		capital and			accumulated
	income		income		capital gains		other losses			earnings

RMA New York		7,181		33,099		—		—			40,280
RMA New Jersey		2,420		5,604		—		—			8,024

In accordance with US Treasury regulations, Money Market Portfolio has elected to defer $29,150 of net realized capital losses arising after October 31, 2009. Such losses are treated for tax purposes as arising on July 1, 2010.

To reflect reclassifications arising from permanent “book/tax” differences for the year ended June 30, 2010, the U.S. Government Portfolio’s accumulated net realized loss was decreased $137,697 and paid-in-capital was decreased $137,697. This difference is primarily due to dividend reclassification.

As of and during the year ended June 30, 2010, the Funds did not have any liabilities for any unrecognized tax positions. The Funds recognize interest and penalties, if any, related to unrecognized tax positions as income tax expense in the Statements of operations. During the year ended June 30, 2010, the Funds did not incur any interest or penalties.

Each of the tax years in the four year period ended June 30, 2010, remains subject to examination by the Internal Revenue Service and state taxing authorities.

The Boards of Directors/Trustees and Shareholders of UBS RMA:
Money Market Portfolio
U.S. Government Portfolio
Tax-Free Fund Inc.
California Municipal Money Fund
New York Municipal Money Fund
New Jersey Municipal Money Fund

We have audited the accompanying statements of net assets of 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 Managed Municipal Trust (comprising, respectively, UBS RMA California Municipal Money Fund and UBS RMA New York Municipal Money Fund); and UBS RMA New Jersey Municipal Money Fund (the sole series comprising UBS Municipal Money Market Series) (collectively, the “Funds”) as of June 30, 2010, 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 reguire 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, 2010 by correspondence with the custodian and others, or by other appropriate auditing procedures where replies from others were not received. We believe that our audits provide a reasonable basis for our opinion.

Annual Report
June 30, 2010

UBS Retirement Money Fund

August 17, 2010

Dear shareholder,
We present you with the annual report for UBS Retirement Money Fund for the 12 months ended June 30, 2010.

Performance
As of June 30, 2010, the Fund’s seven-day yield was 0.01%, unchanged from 0.01% on June 30, 2009 (after fee waivers/expense reimbursements). (For more on the Fund’s performance, refer to “Performance and portfolio characteristics at a glance” on page 7.)
Investment goal:
Current income consistent
with liquidity and
conservation of capital

Sub-advisor:
Robert Sabatino
UBS Global Asset
Management (Americas) Inc.

Commencement:
July 2, 1988

Dividend payments:
Monthly

Given pockets of weakness in the economy, including continued high unemployment, the Federal Reserve Board (the “Fed”) maintained the federal funds rate at a historically low range between 0.00% and 0.25% 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.) This caused the yields of the securities in which the Fund invests to remain very low, which, in turn, negatively impacted the Fund’s yield.

An interview with Portfolio Manager Robert Sabatino

Q.	How would you describe the economic environment during the reporting period?
A.	While certain economic data somewhat moderated toward the end of the reporting period, the economy, overall, continued to expand. After four consecutive quarters of declining gross domestic product (“GDP”) growth, the US economy started to expand in the third quarter of 2009, and has continued to expand thus far into 2010. Economic growth was supported by the federal government’s $787 billion stimulus program, increased consumer spending and improved manufacturing activity, as companies moved to rebuild inventories amid rising demand.
Q.	How did the Fed react to the economic environment?
A.	Although the economy continued to expand during the last three quarters of the reporting period, the Fed remained concerned about

	continued high unemployment, which was an elevated 9.5% in June 2010. As a result, the Fed maintained its highly accommodative monetary policy, keeping the fed funds rate within a range of 0.00% to 0.25%—a historic low.The Fed has now held short-term interest rates steady since December 2008. At its meeting in June 2010, the Fed reasserted the rationale for this policy stating that it “will maintain the target range for the federal funds rate at 0 to 1/4 percent and continues to anticipate that economic conditions, including low rates of resource utilization, subdued inflation trends, and stable inflation expectations, are likely to warrant exceptionally low levels of the federal funds rate for an extended period.”
Q.	How did you position the Fund during the reporting period?
A.	When the reporting period began, the Fund’s weighted average maturity was 41 days. As the reporting period continued and the credit markets stabilized, we increased the Fund’s weighted average maturity significantly, reaching 49 days on December 31, 2009.
	However, during the second half of the reporting period, we reduced the Fund’s weighted average maturity, ending the period at 39 days, in order to minimize pricing volatility and to meet potential redemption requests in light of the effectiveness of the Securities and Exchange Commission’s new requirements related to money market funds (see below for more information). In addition, it was our expectation that interest rates would rise as the Fed began to take steps—ahead of any moves to increase the fed funds rate—to remove current high levels of liquidity from the market.
Q.	What level of portfolio diversification did you maintain during the reporting period?
A.	At the issuer level, we maintained a greater-than-usual level of diversification over the fiscal year by investing in smaller positions, with the goal of reducing risk and keeping the Fund highly liquid. As the economic environment improved over the period, we gradually increased our single issuer exposure, typically purchasing up to 3.00% in single nongovernment issuers toward the end of the reporting period. The Fund is generally able to hold up to 5.00% in any one issuer (subject to certain exceptions).
Q.	What types of securities did you emphasize over the period?
A.	We increased the Fund’s exposure to commercial paper and certificates of deposit over the 12-month period. In addition, we decreased the Fund’s exposure to US government and agency obligations, short-term

2

UBS Retirement Money Fund

	corporate obligations and repurchase agreements. (Repurchase agreements are transactions in which the seller of a security agrees to buy it back at a predetermined time and price or upon demand.)
Q.	What factors do you believe will affect the Fund over the coming months?
A.	While the worst of the global recession appears to be over, a number of uncertainties remain regarding the sustainability of the economic recovery. Unemployment remains high and the government’s stimulus programs are scheduled to largely expire as the year progresses. Given this environment, yields on money market securities could remain low, and there could be periods of increased market volatility.
Q.	How will regulatory changes announced earlier this year impact the Fund?
A.	On January 27, 2010, the Securities and Exchange Commission (“SEC”) adopted rule amendments designed to strengthen the regulations governing money market funds. The amendments impose new liquidity, credit quality and maturity limits. They also enhance disclosures by, among other things, requiring the monthly posting of portfolio holdings reports (beginning in October 2010). UBS Global Asset Management (Americas) Inc. (“UBS Global AM”) welcomes the SEC’s approval of these new requirements. We believe that they will fortify the money market sector and are consistent with our long-standing conservative approach to the management of our US money market funds.

This letter is intended to assist shareholders in understanding how the Fund performed during the 12 months ended June 30, 2010. The views and opinions in the letter were current as of August 17, 2010. They are not guarantees of performance or investment results and should not be taken as investment advice.

UBS Retirement Money Fund

Understanding your fund’s expenses (unaudited)

As a shareholder of the Fund, you incur ongoing costs, including management fees, service fees (12b-1 fees) and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example below is based on an investment of $1,000 invested at the beginning of the period and held for the entire period, January 1, 2010 to June 30, 2010.

Actual expenses

The first line in the table below provides information about 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 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 table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 the Fund and other funds. To do so, compare this 5% hypothetical example 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 in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds, if those other 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.

“Actual—Ending account value” may not be reflective of a shareholder’s actual investment experience during periods of very low interest rates. While the Fund declares dividends daily and pays them monthly, the amounts are rounded to the nearest $0.01 on a daily basis with respect to each investor’s account. As a result, investors whose Fund account balances earn daily dividends that total less than one half a cent on any given day will not accrue any daily dividends on that day.

UBS Retirement Money Fund

Notes to financial statements

Organization and significant accounting policies
UBS RMA Money Fund Inc. (the “Corporation”) was incorporated in the state of Maryland on July 2, 1982 and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended, as an open-end, diversified management investment company. The Corporation is a series mutual fund and currently has three portfolios: UBS Retirement Money Fund (the “Fund”), UBS RMA Money Market Portfolio and UBS RMA U.S. Government Portfolio. The financial statements for the UBS RMA Money Market Portfolio and UBS RMA U.S. Government Portfolio are not included herein.

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

In June 2009, the Financial Accounting Standards Board (“FASB”) established the FASB Accounting Standards Codification™ (“Codification”) as the single source of authoritative accounting principles recognized by the FASB in the preparation of financial statements in conformity with US generally accepted accounting principles (“GAAP”). The Codification supersedes existing and nongrandfathered, non-SEC accounting and reporting standards. The Codification did not change GAAP but rather organized it into a hierarchy where all guidance within the Codification carries an equal level of authority. The Codification became effective on July 1, 2009. The Codification did not have a material effect on the Fund’s financial statements.

The preparation of financial statements in accordance with GAAP requires the Fund’s management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results

Notes to financial statements

could differ from those estimates. The following is a summary of significant accounting policies:

Valuation of investments—Investments are valued at amortized cost. Periodic review and monitoring of the valuation of the securities held by the Fund is performed in an effort to ensure that amortized cost approximates market value.

GAAP requires disclosure surrounding the various inputs that are used in determining the value of the Fund’s investments. These inputs are summarized into the three broad levels listed below:

Level 1—Unadjusted quoted prices in active markets for identical investments.
Level 2—Other significant observable inputs, including but not limited to, quoted prices for similar investments, interest rates, prepayment speeds and credit risks.
Level 3 —Unobservable inputs inclusive of the Fund’s own assumptions in determining the fair value of investments.

In accordance with the requirements of GAAP, a fair value hierarchy has been included near the end of the Fund’s Statement of net assets.

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about Fair Value Measurements”. ASU No. 2010-06 requires reporting entities to make new disclosures about amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3, and information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. The new and revised disclosures are required to be implemented for annual and interim periods beginning after December 15, 2009 except for the disclosures surrounding purchases, sales, issuances and settlements on a gross basis in the reconciliation of Level 3 fair value measurements, which are effective for annual and interim periods beginning after December 15, 2010. The Fund adopted the new disclosures during the reporting period and did not have any transfers in and out of Level 1 and Level 2.

Notes to financial statements

Repurchase agreements—The 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. The Fund maintains custody of the underlying securities or 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 Fund and its 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 default of the obligation to repurchase, the Fund generally has 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, the 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. The 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”).

Under certain circumstances, the Fund may engage in a repurchase agreement transaction with a yield of zero in order to invest cash amounts remaining in its portfolio at the end of the day in order to avoid having the Fund assessed a fee for uninvested cash held in a business account at a bank.

Investment transactions, investment income and expenses—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. Discounts are accreted and premiums are amortized 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 GAAP. These “book/tax” differences

20

Notes to financial statements

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 Fund to meet their obligations may be affected by economic and political developments, including those particular to a specific industry, country or region.

Investment advisor and administrator
The Fund’s Board of Directors has approved an 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 Fund. In accordance with the Advisory Contract, the 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:

Average daily net assets	Annual rate
Up to $1.0 billion	0.50	%
In excess of $1.0 billion and up to $1.5 billion	0.44	%
Over $1.5 billion	0.36	%

Effective August 1, 2006, UBS Financial Services Inc. has agreed to waive a portion of this fee so that it is reduced to the following:

Average daily net assets	Annual rate
Up to $300 million	0.50	%
In excess of $300 million and up to $750 million	0.44	%
Over $750 million	0.36	%

This fee waiver shall continue in effect unless it is terminated by a vote of a majority of those directors of the Fund who are not parties to the Advisory Contract or “interested persons” of any such party (as defined in the Investment Company Act of 1940, as amended), cast in person at a meeting called for the purpose of voting on such termination, or by vote of a majority of the outstanding voting securities of the Fund.

For the year ended June 30, 2010, UBS Financial Services Inc. waived $1,020,000 of investment advisory and administration fees pursuant to

21

UBS Retirement Money Fund

Notes to financial statements

the above described waiver arrangement. At June 30, 2010, the Fund owed UBS Financial Services Inc. $64,682 for investment advisory and administration fees, net of fee waivers and expense reimbursements.

UBS Financial Services Inc. has undertaken to waive fees and/or reimburse expenses in the event that current Fund yields drop below a certain level. This additional undertaking is voluntary and not contractual and may be terminated at any time. For the year ended June 30, 2010, UBS Financial Services Inc. voluntarily waived investment advisory and administration fees and reimbursed expenses totaling $7,163,744.

UBS Global AM serves as sub-advisor and sub-administrator to the Fund pursuant to a sub-advisory and sub-administration contract (“Sub-Advisory Contract”) between UBS Financial Services Inc. and UBS Global AM. In accordance with the Sub-Advisory Contract, UBS Financial Services Inc. (not the Fund) pays UBS Global AM a fee, accrued daily and paid monthly, at an annual rate of 0.08% of the Fund’s average daily net assets.

Additional information regarding compensation to affiliate of a board member
Professor Meyer Feldberg serves as a senior advisor to Morgan Stanley, a financial services firm with which the Fund may conduct transactions, resulting in him being an interested board member of the Fund. The Fund has 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, 2010, the Fund purchased and sold certain securities (e.g., fixed income securities) in principal trades with Morgan Stanley having an aggregate value of $568,398,487. 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 it represents a small portion of the total value of the transactions.

Distribution plan
UBS Global Asset Management (US) Inc. (“UBS Global AM (US)”) is the principal underwriter of the Fund’s shares and has appointed UBS Financial Services Inc. as dealer for the sale of those shares. Under the plan of

22

UBS Retirement Money Fund

Notes to financial statements

distribution, the Fund pays 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 the Fund’s average daily net assets. Currently, UBS Global AM (US) is compensated for providing such services at an annual rate of 0.125% of the Fund’s average daily net assets. At June 30, 2010, the Fund owed UBS Global AM (US) $161,399 for service fees.

Transfer agency related services
UBS Financial Services Inc. provides certain services to the Fund pursuant to a delegation of authority from BNY Mellon Investment Servicing (US) Inc. (formally PNC Global Investment Servicing (U.S.) Inc.) (“BNY Mellon”), the Fund’s transfer agent, and is compensated for these services by BNY Mellon, not the Fund.

For the year ended June 30, 2010, UBS Financial Services, Inc. received from BNY Mellon, not the Fund, $1,089,099 of the total transfer agency and related services fees paid by the Fund to BNY Mellon.

Securities lending
The Fund may lend securities up to 33¹/₃% 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. The Fund will regain ownership of loaned securities to exercise certain beneficial rights; however, the Fund may bear the risk of delay in recovery of, or even loss of rights in, the securities loaned should the borrower fail financially. The 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. State Street Bank and Trust Company serves as the Fund’s lending agent. At June 30, 2010, the Fund did not have any securities on loan.

Other liabilities and components of net assets
At June 30, 2010, the Fund had the following liabilities outstanding:

Payable for investments purchased	$15,000,000

US Treasury Temporary Guarantee Program for Money Market Funds
The Fund participated in the US Treasury Department Temporary Guarantee Program for Money Market Funds. The program covered shareholders of participating money market funds as of the close of business on September 19, 2008. The program expired on September 18, 2009. The Fund bore the cost of participating in this program, to the extent not offset by UBS Global AM’s fee waivers/voluntary expense reimbursements. The Fund paid a fee of 0.01% of the value of the Fund’s outstanding shares on September 19, 2008 (valued at $1.00 per share) for participation in the program for the initial coverage period of September 19, 2008, through December 18, 2008. The program was first extended until April 30, 2009, and the Fund paid a fee calculated in the same manner but at the rate of 0.015% for continued participation in the program through that date. The program was then extended a final time, providing coverage through September 18, 2009. In April, the Fund paid an additional fee for continued coverage for the period May 1, 2009, through September 18, 2009, calculated in the same manner and at the same 0.015% rate as for the initial extension period.

Federal tax status
The Fund intends to distribute all or substantially 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

24

UBS Retirement Money Fund

Notes to financial statements

income taxes is required. In addition, by distributing during each calendar year substantially all of its net investment income, net realized capital gains and certain other amounts, if any, the Fund intends not to be subject to a federal excise tax.

The tax character of distributions paid to shareholders by the Fund during the fiscal years ended June 30, 2010 and June 30, 2009 was ordinary income.

At June 30, 2010, the characteristics of accumulated earnings on a tax basis were undistributed ordinary income of $3,000 and accumulated realized capital and other losses of $1,374.

As of and during the year ended June 30, 2010, the Fund did not have any liabilities for any unrecognized tax positions. The Fund recognizes interest and penalties, if any, related to unrecognized tax positions as income tax expense in the Statement of operations. During the year ended June 30, 2010, the Fund did not incur any interest or penalties.

Each of the tax years in the four year period ended June 30, 2010, remains subject to examination by the Internal Revenue Service and state taxing authorities.

Report of Ernst & Young LLP, independent registered public accounting firm

The Board of Directors and Shareholders of
UBS Retirement Money Fund

We have audited the accompanying statement of net assets of UBS Retirement Money Fund (the “Fund”) (one of the series comprising UBS RMA Money Fund Inc.) as of June 30, 2010, and the related statement 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 five years in the period then ended. 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 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 Fund’s 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 Fund’s 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, 2010, by correspondence with the custodian and others, or by other appropriate auditing procedures where replies from others were not received. 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 UBS Retirement Money Fund at June 30, 2010, the results of its operations for the year then ended, the changes in its 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.

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.

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.

	2010	2009
Covered Services	$48,025	$39,690

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.
