Introduction

September 19, 2007

Dear UBS PACE^SM Shareholder,

We are pleased to provide you with the annual report for the UBS PACE Portfolios, comprising the UBS PACE Select Advisors Trust. This report includes summaries of the performance of each Portfolio and commentaries from the individual investment advisors regarding the events that affected Portfolio performance during the fiscal year ended July 31, 2007. Please note that the opinions of the advisors do not necessarily represent those of UBS Global Asset Management (Americas) Inc.

US economic growth fluctuated during the fiscal year. After expanding 2.4% in the second quarter of 2006, gross domestic product (GDP) grew 1.1% and 2.1% in the third and fourth quarters of the year, respectively. The economy then trailed off significantly over the first three months of 2007, with GDP growing a tepid 0.6%—its slowest rate since the fourth quarter of 2002. The weakening economy was attributed, in part, to the troubles in the housing market. The economy then picked up steam in the second quarter, as the preliminary estimate for GDP growth came in at 4.0%.

Economic news was largely positive on the international front. A report issued by the Organization for Economic Cooperation and Development (OECD) estimated that during 2007, growth in Europe and Japan was expected to eclipse that of the US for the first time since 2001. The OECD projected that the US economy would expand 2.1% in 2007, compared with 3.3% in 2006. In contrast, the estimates for growth during 2007 in the Eurozone and Japan were 2.7% and 2.4%, respectively.

Despite periods of extreme volatility late in the reporting period, the US stock market generated solid results during the fiscal year. Over this period, the overall stock market, as measured by the S&P 500 Index, returned 16.13%. After rising during much of the period, stock prices began to fall sharply toward the end of July. The market's decline was largely attributed to the escalating troubles in the housing and subprime mortgage markets, liquidity concerns, some mixed corporate earnings results and surging oil prices. The international equity markets also gyrated late in the period but, overall, generated strong results, as the MSCI Europe, Australasia and Far East (EAFE)¹ Index rose 24.42% over the reporting period. Emerging markets equities performed even better, as the MSCI Emerging Markets (EM) Index² gained 50.94% during the 12-month period ended July 31, 2007.

The global bond markets also generated positive, albeit more modest gains over the 12-month reporting period. In the US, the Federal Reserve Board (the "Fed") kept short-term interest rates on hold at 5.25%. (However, after period end, at its September 18, 2007 meeting, the Fed lowered rates by 0.50%.) Due in part to a "flight to quality" amid the troubles in the stock and mortgage markets, both short- and long-term yields declined over the period. During that time, the overall US bond market, as measured by the Lehman Brothers U.S. Aggregate Bond Index, returned 5.58%.

Given solid economic growth and monetary tightening by many central banks, the international bond markets lagged their US counterparts, and the JP Morgan Global Government Bond Index returned 4.78%.

1.  The MSCI EAFE Index consists of almost 1,000 stocks in 21 countries outside North and South America, and represents approximately 85% of the total market capitalization in these countries.

2.  The MSCI EM Index measures equity market performance in the global emerging markets, and consists of approximately 25 market country indexes, including Argentina, Brazil, Malaysia and Thailand.

Introduction

Lower-quality fixed income securities, such as high yield bonds and emerging markets debt, generated better results despite weakening late in the period, as the Lehman Brothers High Yield Index and JP Morgan Emerging Markets Bond Index (EMBI) Global Diversified¹ returned 6.56% and 6.89%, respectively.

Given the recent volatility in the financial markets, there are conflicting views of what is in store for investors for the remainder of the year. As such, we believe it is extremely important to work closely with a professional financial advisor. He or she can help you maintain a well-diversified portfolio and remain focused on your long-term goals. As always, we appreciate your continued support. If you have any questions regarding your portfolio or your investment program, please contact your financial advisor.

Sincerely,

Kai R. Sotorp
President, UBS PACE Select Advisors Trust
Head of the Americas, UBS Global Asset Management (Americas) Inc.

1.  The JP Morgan EMBI Global Diversified Index is an unmanaged Index of debt instruments of 31 emerging countries.

This report is intended to assist investors in understanding how the Portfolios performed during the 12-month period ended July 31, 2007. The views expressed in the Advisors' Comments sections are as of the end of the reporting period, reflect performance results gross of fees and expenses, and are those of the investment advisors. Advisors' comments on portfolios that have more than one manager are reflective of their portion of the portfolio only. The views and opinions in this report were current as of September 19, 2007. They are not guarantees of performance or investment results and should not be taken as investment advice. Investment decisions reflect a variety of factors, and the Advisors reserve the right to change their views about individual securities, sectors and the markets at any time. As a result, the views expressed should not be relied upon as a forecast of a Portfolio's future investment intent.

Update regarding portfolio changes

Special updates:

As noted in the UBS PACE Select Advisors Trust semiannual report dated January 31, 2007, the following changes were approved by the Trust's Board, and implemented earlier in 2007.

UBS PACE Global Real Estate Securities Investments – The global market in real estate-related securities, especially real estate investment trusts ("REITS"), has expanded over recent years and, with it, the availability of global investment opportunities. To that end, the Portfolio may increase its exposure to non-US global real estate-related securities opportunities as markets warrant, and as permitted by its investment policy. This should provide the Portfolio with greater global diversification and the potential to capture additional sources of return. Consequently, the Portfolio's name has been changed to UBS PACE Global Real Estate Securities Investments from UBS PACE Real Estate Securities I nvestments, to better reflect this aspect of its investment opportunity set. The name change became effective on March 26, 2007.

UBS PACE Small/Medium Co Growth Equity Investments – Delaware Management Company has been replaced by Copper Rock Capital Partners, LLC ("Copper Rock"), as one of the three advisors to the Portfolio. AG Asset Management LLC (formerly known as ForstmannLeff LLC) and Riverbridge Partners, LLC continue to manage portions of the Portfolio.

After the semiannual report was issued, the following significant event occurred:

Change in advisor for UBS PACE Large Co Growth Equity Investments – Wellington Management Company, LLP ("Wellington Management") assumed investment advisory responsibility with respect to a portion of the Portfolio, replacing GE Asset Management, in June 2007. Marsico Capital Management, LLC and SSgA Funds Management, Inc. continue to manage portions of the Portfolio as allocated by UBS Global Asset Management.

Additionally, while this annual report provides important information about the Portfolios for their fiscal period ended July 31, 2007, subsequent to the current fiscal year end, the following significant changes were approved by the Trust's Board and are effective as noted:

Change in advisor for UBS PACE Global Fixed Income Investments – Fischer Francis Trees & Watts, Inc. and its affiliates (collectively, "FFTW"), had served as an investment advisor to UBS PACE Global Fixed Income Invetments, along with Rogge Global Partners plc ("Rogge Global Partners"). Effective August 23, 2007, FFTW no longer serves as an investment advisor to the Portfolio, and Rogge Global Partners serves as the sole investment advisor to the Portfolio. In connection with its management of the Portfolio, Rogge Global Partners may increase the Portfolio's investments in certain derivative instruments, such as credit default swaps and inflation-linked swaps. The Board of Trustees of UBS PACE Select Advisors Trust has also approved a change to the non-fundamental investment policies of the Portfolio, in order to increase the Portfolio's abil ity to invest in high yield and emerging markets debt (and emerging markets currencies). This change will become effective as of October 1, 2007. UBS Global Asset Management believes that this policy change will enhance the Portfolio's ability to seek increased returns, but does involve some additional risk.

Update regarding portfolio changes

Fee waiver/expense reimbursement agreements for five UBS PACE Fixed Income Portfolios – Effective August 1, 2007, five of the UBS PACE Fixed Income Portfolios have entered into revised fee waiver/expense reimbursement agreements with UBS Global Asset Management, the Portfolios' manager, to further reduce the Portfolios' expenses. For the following PACE Portfolios, the ordinary annual portfolio operating expenses are being capped at lower "net expense" levels through November 30, 2008:

UBS PACE Government Securities Fixed Income Investments

UBS PACE Global Fixed Income Investments

UBS PACE Intermediate Fixed Income Investments

UBS PACE Strategic Fixed Income Investments

UBS PACE Municipal Fixed Income Investments

Further information regarding the fee waiver/expense reimbursement arrangements is contained in a "subsequent events" note on page 331.

Change in Investment Policy: UBS PACE Large Co Growth Equity Investments and UBS PACE Large Co Value Equity Investments

At a meeting held on September 19, 2007, the Board approved a change to the investment policies of UBS PACE Large Co Growth Equity Investments and UBS PACE Large Co Value Equity Investments. Under the current policy, large capitalization companies refer to companies with a total market capitalization of $6.0 billion or greater at the time of purchase. Effective November 30, 2007, large capitalization companies will mean companies with a total market capitalization of $3.0 billion or greater at the time of purchase.

UBS Global Asset Management (Americas) Inc., the Portfolios' manager, recommended this change and believes that this change may benefit the Portfolios by affording the Portfolios' investment advisors the flexibility to implement each Portfolio's investment strategy by selecting a greater number of companies represented in the Portfolio's benchmark.

Change in subadvisor for UBS PACE Alternative Strategies Investments. At the recommendation of UBS Global Asset Management, the Trust's Board appointed Goldman Sachs Asset Management, L.P. ("GSAM") to serve as an investment advisor to the Portfolio, effective September 11, 2007. Analytic Investors, Inc. and Wellington Management Company, LLP will also continue to manage portions of the Portfolio as allocated by UBS Global Asset Management.

Please note: This "Update regarding portfolio changes" section describes certain of the more significant changes that have occurred over the past several months, but does not purport to be a complete summary of all changes.

Performance

For the 12 months ended July 31, 2007, the Portfolio returned 4.86% (before the deduction of the maximum UBS PACE Select program fee; after the deduction of the maximum UBS PACE Select program fee, the Portfolio returned 3.29%). In comparison, the 90-Day US T-Bill Index (the "Index") returned 5.06%, and the median return for the Lipper Money Market Funds category was 4.68%. (Returns over various time periods are shown in the "Performance at a Glance" table on page 9. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions.)

Market review

US economic growth was mixed during the fiscal year. After expanding 2.4% in the second quarter of 2006, gross domestic product (GDP) grew 1.1% and 2.1% in the third and fourth quarters of the year, respectively. The economy then weakened further during the first quarter of 2007, with GDP growing a modest 0.6%. This was attributed, in part, to the faltering housing market. The economy then appeared to rebound in the second quarter, as the preliminary estimate for GDP growth came in at 4.0%.

Just prior to the start of the review period, the Federal Reserve Board (the "Fed") raised the federal funds rate by 25 basis points (0.25%)—bringing it to 5.25%—where it remained throughout 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.) The Fed has repeatedly indicated that future rate movements would be data-dependent, as it attempts to ward off inflation and to keep the economy growing at a reasonable pace.

Following the conclusion of the reporting period, the Fed reacted to concerns over subprime lending (a type of lending that relies on risk-based pricing to serve borrowers who cannot obtain credit in the prime market) by providing greater amounts of liquidity to the market in order to facilitate normal market operations. The Fed followed this up by lowering the fed funds rate by 0.50% at its September 18, 2007 meeting, bringing it to 4.75%. The Fed has stated that it plans to continue monitoring the risks of rising inflation along with the potential for slower economic growth.

Advisor's comments

We initially focused on securities with maturities of three to six months, as the future direction of short-term interest rates was uncertain. This strategy allowed us to take advantage of the yield curve position, which was inverted for most of the period, and to lock in higher yields, while at the same time insulating the Portfolio to some degree from a possible Fed rate cut. (An inverted yield curve occurs when long-term interest rates have lower yields than short-term interest rates.)

Portfolio Manager:

Michael H. Markowitz

Objective:

Current income consistent with preservation of capital and liquidity.

Investment process:

The Portfolio is a money market mutual fund and seeks to maintain a stable price of $1.00 per share, although it may be possible to lose money by investing in this Portfolio. The Portfolio invests in a diversified portfolio of high-quality money market instruments of governmental and private issuers. Security selection is based on the assessment of relative values and changes in market and economic conditions.

Advisor's comments – concluded

Later in the fiscal year, we began using a "barbell" strategy (in which the maturities of securities in a portfolio are concentrated at opposite ends of the yield curve). While we continued to buy shorter-term securities, we also sought to extend the Portfolio's weighted average maturity with longer-term money market securities maturing within nine to 13 months. This was beneficial to performance, as the yield on one-year money market securities rose steadily higher late in the reporting period.

As always, quality, liquidity and yield remained paramount in our selection process for the Portfolio. We maintained relatively large positions in commercial paper (a short-term security often backed by a guarantee or a letter of credit from a bank or other entity), although we decreased this somewhat over the reporting period. Other short-term corporate obligations and certificates of deposit also comprised a fair amount of the Portfolio. Within these sectors, we found variable-rate securities, which offer interest rates that reset periodically, to be attractive, given the uncertainty of interest rate movements by the Fed. We purchased variable-rate securities linked to the fed funds rate, as well as those linked to the one-month and three-month LIBOR. (The LIBOR, or the London Interbank Offered Rate, is among the most common of benchmark interest rate indexes used to make adjustments to adjustable-rate securities.)

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 4.71% (before the deduction of the maximum UBS PACE Select program fee; 3.15% after the deduction of the maximum UBS PACE Select program fee). In comparison, the Lehman Brothers Mortgage-Backed Securities Index (the "Index") returned 5.60%, and the median return for the Lipper Intermediate US Government Funds category was 4.87%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 17. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

The Federal Reserve Board (the "Fed") remained on hold through the year ended July 31, 2007, after pausing in August 2006 with the federal funds rate at 5.25%. (The federal funds rate, or "fed funds" rate, is the rate that banks charge one another for funds they borrow on an overnight basis.) Even as worries about the subprime mortgage sector developed late in the review period, the Fed focused on stronger economic data, making it difficult for them to lower rates as they remained concerned about inflation. (Subprime mortgage loans are riskier loans, in that they are made to borrowers unable to qualify under traditional, more stringent criteria due to a limited or blemished credit history.) Tight labor markets kept the unemployment rate relatively low and produced real wage gains for consumers, which helped offset headwinds from the residential property market. In addition, measures of core inflation (consumer price inflation wi th the volatile food and energy prices stripped out) remained above the Fed's targeted range. Weakness in the subprime mortgage sector produced a significant tightening of credit conditions for lower-quality and first-time borrowers, yet another blow to an already soft housing market. The mortgage credit derivatives market widened significantly in response to the weakness.

Advisor's comments

During the fiscal year, the mortgage sector underperformed US Treasuries. During the first half of the period, the mortgage market was unable to withstand the pressures of the dramatic flattening of the Treasury bond yield curve (a yield curve flattens as the spread—or difference—between yields on long- and short-term Treasuries decreases). The deterioration in the mortgage credit market intensified in early 2007 as subprime loan delinquencies surpassed their 2001 peak, and many subprime lenders went out of business. Mortgages continued to stumble through the rest of the period, as the 10-year Treasury bond yield reached a five-year high. The Treasury bond selloff triggered a wave of MBS selling, as US banks and mortgage service

Investment Advisor:

Pacific Investment Management Company LLC ("PIMCO")

Portfolio Manager:

W. Scott Simon

Objective:

Current income

Investment process:

The Portfolio invests primarily in mortgage-backed securities, along with government fixed income securities, including other types of bonds. The Portfolio also invests, to a lesser extent, in investment grade bonds of private issuers, including those backed by mortgages or other assets. The Portfolio's duration normally ranges between one and seven years. (Duration is a measure of a bond portfolio's sensitivity to interest rate changes.) PIMCO establishes duration targets based on its expectations for changes in interest rates, and then positions the Portfolio to take advantage of yield curve shifts. Securities are chosen for their value relative to other similar securities.

Advisor's comments – concluded

companies sought to shed their exposure to these securities. Later in June 2007, news about the failure of two subprime-related hedge funds rekindled fears about subprime credit, and sparked a flight to quality as investors moved out of spread products into Treasury bonds (spread product refers to taxable bonds that are not Treasury securities). This shift continued into July and drove US Treasury bond yields lower.

In this environment, the Portfolio's duration was held above the benchmark, which benefited performance as interest rates fell over the fiscal year (duration is a measure of an investment's sensitivity to interest rate changes). Exposure to shorter maturities of the US yield curve through the use of eurodollar futures detracted from returns during the year, as expectations of the Fed easing diminished. (A eurodollar is US currency held in banks outside the US; futures refers to a contract that represents an obligation to exchange an instrument at a set price on a future date.) Coupon selection helped performance, as technical supply and demand factors created pockets of rich and inexpensive issues (the coupon is the interest rate on a fixed income security, as determined upon issuance). Exposure to high-quality, cash-equivalent, asset-backed securities added income to the Portfolio, and their prices remained relatively stable du ring the 12-month period. An overweight to 15-year conventional securities (FNMA/FHLMC) added to returns, as they outpaced the 30-year sector and broader index on a duration-adjusted basis. An overweight to 30-year conventional issues (FNMA/FHLMC) detracted from returns, as these securities underperformed their GNMA counterparts, also on a duration-adjusted basis. An overweight to 30-year FNMA 6.5% coupons helped returns, as this coupon outpaced the broader market. Finally, an overweight to discount 30-year issues detracted from returns as discount coupons underperformed premium coupons. (A discount bond is valued at a price less than its face value; a premium bond is priced higher than its face value.)

Special considerations

The Portfolio may be appropriate for long-term investors seeking current income who are able to withstand short-term fluctuations in the fixed income markets in return for potentially higher returns over the long term. The yield and value of the Portfolio change every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the issuers in which the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

Additionally, UBS Global AM and the Portfolio have entered into a written fee waiver agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees to the extent necessary to reflect the lower sub-advisory fee paid by UBS Global AM to PIMCO beginning August 1, 2007.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 5.17% (before the deduction of the maximum UBS PACE Select program fee; 3.60% after the deduction of the maximum UBS PACE Select program fee). In comparison, the Lehman Brothers Intermediate Government/Credit Index (the "Index") returned 5.59%, and the median return for the Lipper Short-Intermediate Investment Grade Debt Funds category was 4.63%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 29. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

During the 12-month period, the economy remained relatively stable, although growth continued to moderate. On July 18, 2007, Federal Reserve Board (the "Fed") Chairman Bernanke appeared before Congress to present his semiannual monetary policy testimony. Policy makers trimmed Fed forecasts for the economy's expansion in 2007 and in 2008, while projections for inflation remained unchanged. Mr. Bernanke indicated that the housing slump remains a risk to the outlook for growth, adding that there will be significant losses from securities backed by subprime mortgages. As real gross domestic product ("GDP") continued to plateau, market sentiment suggested that the Fed may cut interest rates. At period end, fed funds futures had priced in a 92% chance of a 0.25% cut by the December 11, 2007, Fed meeting. In fact, the Fed cut interest rates by 0.50% at its September 18, 2007 meeting.

While the early portion of the reporting period was relatively uneventful for the markets, the latter half of the year saw a tremendous spike in volatility and activity as issues in the subprime mortgage space spread across the financial markets. The subprime meltdown triggered a repricing of risk, causing dramatic widening in credit spreads, along with widening across all swap-like sectors of the fixed income market. (The spread is the difference between the yield paid on US Treasury bonds and higher-risk securities.)

Against this economic backdrop, the global markets experienced a flight to quality. The fixed income market generally performed well during the period, with the Lehman Brothers Aggregate Index returning 5.58%. Interest rates moved steadily lower throughout the period, with two-year, five-year, 10-year, and 30-year Treasury bond yields declining 0.43%, 0.33%, 0.24% and 0.16%, respectively.

Portfolio Managers:

Team

Objective:

Current income, consistent with reasonable stability of principal

Investment process:

BlackRock decides to buy specific bonds based on its credit analysis and review. BlackRock strives to add value while keeping the Portfolio's duration within a narrow band relative to the Lehman Brothers Intermediate Government/Credit Index. To accomplish this, BlackRock employs an analytical process that involves evaluating macroeconomic trends, technical market factors, yield-curve exposure and market volatility. Once BlackRock establishes the investment themes on duration, yield curve exposure, convexity, sector weighting, credit quality and liquidity, the Portfolio's investments are diversified by sector, subsector and security.

Advisor's comments

During the first half of the period, the Portfolio maintained a duration shorter than the Index's, which detracted from relative performance as yields declined (duration is a measure of an investment's sensitivity to interest rate changes). The Portfolio extended its duration at the end of the period, maintaining a relatively neutral stance compared with the Index.

The Portfolio's underweight to agency securities was beneficial to performance as the sector lagged Treasury bonds by 27 basis points during the period (a basis point is one one-hundredth of one percent). The Portfolio maintains this defensive posture in the agency sector as, in our view, valuations remain unattractive, while the potential for increased regulatory scrutiny persists, putting near-term pressure on spreads.

The Portfolio maintained an allocation to mortgage backed securities, which detracted from performance as the sector posted negative returns during the fiscal year. During the latter part of the period, volatility in the mortgage sector increased. The Portfolio took this opportunity to increase its allocation to 30-year mortgage pass-through securities. The Portfolio continues to maintain an allocation to floating rate securities and collateralized mortgage obligations (CMOs).

The Portfolio has held a significant position in commercial mortgage backed securities (CMBS). We continue to favor the CMBS sector, as we believe it offers a better relative value versus sectors such as corporate bonds and agencies. However, this sector's returns lagged the returns of Treasury bonds, which detracted from relative performance. In our opinion, higher-rated CMBS classes, both new and old, continue to represent attractive relative value, as we believe they offer stable, high-credit-quality cash flows and less idiosyncratic risk than other spread sectors. (Idiosyncratic risk is the risk of price change due to the unique circumstances of a specific security, as opposed to the overall market.)

The Portfolio maintained an underweight in the corporate bond sector throughout the reporting period. This benefited performance as corporate bonds performed poorly over the fiscal year. The corporate credit component of the Index posted a return that was 68 basis points less than Treasury bonds during the fiscal year. Subprime mortgage-related problems, aggressive leveraged buyout/recapitalization financing plans, and several hedge fund closings all weighed on credit spreads during the latter part of the period. Investment grade securities continue to face a number of headwinds, including potential spillover effects from the slowdown in housing, unattractive valuations and event risk. We expect a continued bifurcation between high-quality names and those with headline or operational risk potential, with the number of these names growing as companies look to enhance shareholder value. The Portfolio's holdings continue to be conc entrated in higher-quality credits. While retaining a negative bias toward the corporate bond sector, we believe the Portfolio is positioned to add attractively valued new issues opportunistically.

Special considerations

The Portfolio may be appropriate for long-term investors seeking current income and a reasonable stability of principal. Investors should be able to withstand short-term fluctuations in the fixed income markets. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

The Portfolio has agreed to repay UBS Global AM for any waived fees/reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above.

TIPS  Treasury inflation protected securities ("TIPS") are debt securities issued by the US Treasury whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. The interest rate paid by the TIPS is fixed, while the principal value rises or falls based on changes in a published Consumer Price Index ("CPI"). Thus, if inflation occurs, the principal and interest payments on the TIPS are adjusted accordingly to protect investors from inflationary loss. During a deflationary period, the principal and interest payments decrease, although the TIPS principal amounts will not drop below their face amounts at maturity. In exchange for the inflation protection, the TIPS generally pay lower interest rates than typical US Treasury securities. Only if inflation occurs will TIPS offer a higher real yield than a conventional Treasury bond of the same mat urity.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 4.63% (before the deduction of the maximum UBS PACE Select program fee; 3.07% after the deduction of the maximum UBS PACE Select program fee). In comparison, the Lehman Brothers Government/Credit Index (the "Index") returned 5.68%, and the median return for the Lipper Intermediate Investment Grade Debt Funds category was 4.77%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 42. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

The Federal Reserve Board (the "Fed") remained on hold throughout the year ended July 31, 2007, after pausing in August 2006 with the federal funds rate at 5.25%. (The federal funds rate, or "fed funds" rate, is the rate that banks charge one another for funds they borrow on an overnight basis.) Even as worries about the subprime mortgage sector developed late in the period, the Fed focused on stronger economic data, making it difficult for them to lower rates as they remained concerned about inflation. (Subprime mortgage loans are riskier loans, in that they are made to borrowers unable to qualify under traditional, more stringent criteria due to a limited or blemished credit history.) Tight labor markets kept the unemployment rate relatively low and produced real wage gains for consumers, which helped offset headwinds from the residential property market. In addition, measures of core inflation (consumer price inflation with t he volatile food and energy prices stripped out) remained above the Fed's targeted range. Weakness in the subprime mortgage sector produced a significant tightening of credit conditions for lower-quality and first-time borrowers—yet another blow to an already soft housing market. At the end of July 2007, the benchmark 10-year Treasury bond yielded 4.74%, 22 basis points lower than at the start of the period (a basis point is one one-hundredth of one percent).

Advisor's comments

A diversified mix of higher-quality strategies added value during the reporting period. Specifically, maintaining positions that have the potential to benefit from expectations of a steeper yield curve and a repricing of risk began to benefit the Portfolio as the fiscal year progressed. Riskier assets, such as emerging markets bonds and currencies, outperformed during the period as liquidity remained ample—even amid global central bank tightening—while historically low volatility tempted investors to stretch for additional

Investment Advisor:

Portfolio Manager:

William C. Powers

Objective:

Total return consisting of income and capital appreciation.

Investment process:

The Portfolio invests primarily in investment grade bonds of governmental and private issuers in the United States and foreign countries. Its duration (a measure of sensitivity to interest rate changes) normally ranges between three and eight years. PIMCO seeks to invest in the areas of the bond market it considers undervalued, based on such factors as quality, sector, coupon and maturity. PIMCO decides to buy or sell specific bonds based on an analysis of their values relative to other similar bonds. PIMCO monitors the prepayment experience of the Portfolio's mortgage-backed bonds, and will also buy and sell securities to adjust the average portfolio duration, credit quality, yield curve, sector and prepayment exposure, as appropriate.

Advisor's comments – concluded

yield. Interest rate strategies that focused on duration (a measure of an investment's sensitivity to interest rate changes) and the yield curve were slightly positive during the reporting period, as interest rates fell and the yield curve steepened.

An emphasis on mortgage-backed bonds detracted from returns, as this sector underperformed Treasury bonds. This was mainly due to reduced demand from banks and other financial institutions. Another factor causing mortgage securities to underperform was greater-than-expected issuance of fixed rate mortgages, which was attributable to the refinancing of adjustable-rate mortgages.

An underweight to corporate securities was positive for returns, as this sector lagged Treasury bonds. This underperformance was driven by lower investor confidence stemming from the collapse of several hedge funds backed by subprime mortgage loans. A tactical allocation to high yield corporate bonds also added value, as these securities significantly outperformed their high-grade counterparts.

Our non-US positions were a negative for performance, as central banks, both in the Eurozone and the UK, raised interest rates during the period to quell inflation. However, exposure to emerging markets debt added to returns, as credit fundamentals continued to improve in this sector. Finally, exposure to select currencies added to returns as the US dollar depreciated.

Special considerations

The Portfolio may be appropriate for long-term investors seeking total return consisting of income and capital appreciation and who are able to withstand short-term fluctuations in the fixed income markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. In addition, investments in foreign bonds involve special risks. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

TBA  (To Be Announced) Securities are purchased or sold on a forward commitment basis with an approximate principal amount (generally +/- 1.0%) and no definite maturity date. The actual principal amount and maturity date will be determined upon settlement when the specific mortgage pools are assigned.

TIPS  Treasury inflation protected securities ("TIPS") are debt securities issued by the US Treasury whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. The interest rate paid by the TIPS is fixed, while the principal value rises or falls based on changes in a published Consumer Price Index ("CPI"). Thus, if inflation occurs, the principal and interest payments on the TIPS are adjusted accordingly to protect investors from inflationary loss. During a deflationary period, the principal and interest payments decrease, although the TIPS principal amounts will not drop below their face amounts at maturity. In exchange for the inflation protection, the TIPS generally pay lower interest rates than typical US Treasury securities. Only if inflation occurs will TIPS offer a higher real yield than a conventional Treasury bond of the same mat urity.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 3.10% (before the deduction of the maximum UBS PACE Select program fee; 1.56% after the deduction of the maximum UBS PACE Select program fee). In comparison, the Lehman Brothers US Municipal 3-15 year Blend Index (the "Index") returned 4.13%, and the median return for the Lipper Intermediate Municipal Debt Funds category was 3.34%.

Please note: During the fiscal period, the Portfolio changed its benchmark index from the Lehman Brothers Municipal Five-Year Index to the Lehman Brothers US Municipal 3-15 Year Blend Index. This change was implemented to facilitate any extension of the Fund's duration. (For purposes of comparison, the Lehman Brothers Municipal Five-Year Index (the "Index") returned 3.78% over the fiscal year.) (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 59. Please note that the returns shown do not reflect the deduction of taxes that a shareholder could pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

Municipal bond market volatility was relatively low during the majority of the reporting period, with tax-exempt interest rates moving in a somewhat range-bound manner. Municipal yield levels ended the reporting period close to where they began, with the five-year AAA municipal yield increasing by 0.04% to 3.75%, and the 15-year yield (that is, the yield on municipal securities with a stated maturity of 15 years) decreasing by 0.05% to 4.16%. The economic backdrop was highlighted by continued evidence of a weak housing market, moderate economic growth and relatively contained inflationary pressures, which drove a seemingly complacent Federal Reserve Board (the "Fed") to leave the federal funds rate unchanged at 5.25%. (The federal funds rate, or "fed funds" rate, is the rate that banks charge one another for funds they borrow on an overnight basis.) The somewhat steady financial markets were roiled, however, in late June and Jul y, as problems with the subprime mortgage market began to surface. The result was a fear of contagion across all financial markets. (Subprime mortgage loans are riskier loans, in that they are made to borrowers unable to qualify under traditional, more stringent criteria due to a limited or blemished credit history.) Perception of risk shifted with investors demanding assets of the highest credit quality. In what was deemed as a flight-to-quality trade, Treasury bonds exhibited strong performance and municipals were challenged to keep pace.

Investment Advisor:

Standish Mellon Asset Management Company LLC ("Standish Mellon")

Portfolio Manager:

Christine L. Todd

Objective:

High current income exempt from federal income tax

Investment process:

In deciding which securities to buy for the Portfolio, Standish Mellon seeks to identify undervalued sectors or geographical regions of the municipal market, or undervalued individual securities. To do this, Standish Mellon uses credit research and valuation analysis, and monitors the relationship of the municipal yield curve to the Treasury yield curve. Standish Mellon may also make modest duration adjustments based on economic analyses and interest rate forecasts. Standish Mellon generally sells securities if it identifies more attractive investment opportunities within its investment criteria that may improve the Portfolio's return. Standish Mellon also may sell securities with weakening credit profiles or to adjust the average duration of the Portfolio.

Market review – continued

In our opinion, the overall relative attractiveness of municipal bond yields or valuations compared with Treasury bonds improved significantly during the period, amidst a backdrop of heavy municipal bond issuance and the flight to liquidity. Municipal yield changes did not keep pace with the rallying Treasury bond market (10-year AAA municipal bond yields declined by 0.02%, while the 10-year Treasury bond yields declined by 0.20%). New municipal bond issuance reached a record 12-month high of $438 billion during the reporting period. State and local governments continued to tap the capital markets to help fund growing infrastructure needs, such as roads, schools and bridges, as well as to save interest costs by refinancing previously issued, but higher cost, debt. Retail investor demand was moderate, as many investors were not enticed to move out of cash alternatives in the flat yield curve and low yield environment (a flat yiel d curve occurs when all maturities have similar yields). Property and casualty companies, the third largest holder of municipal bonds, exhibited steady demand for municipals as solid profitability trends increased the benefit of tax-favored investment income. Nontraditional investors such as hedge funds, arbitrage desks and even foreign entities absorbed much of the supply and supported the overall liquidity in the market.

Credit trends within the municipal market continued to be positive as total upgrades exceeded downgrades by a margin of 3.7 to 1, according to Moody's Investors Service. The credit outlook for states is positive, although the significant growth in tax revenues experienced in recent years will likely moderate with a weak housing market and spending pressures in areas such as education, Medicaid and infrastructure. States in general have replenished reserve funds since the last economic recession, which may help mitigate the impact of any potential near-term tax revenue shortfalls. Returns on the lowest investment grade bonds (rated BBB) exceeded the highest rated securities (AAA and AA) during the fiscal year as investors sought bonds that provide excess yield in the relatively low interest rate and flat yield curve environment. The relationship between long- and short-maturity municipal yield levels shifted modestly, as the two- to 10-year portion of the municipal yield curve flattened by four basis points to end the period at 30 basis points, well below the long-term average of 109 basis points (a basis point is one one-hundredth of one percent).

Advisor's comments

A diversified mix of sectors and securities offered excess yield, adding value during the reporting period. Income-oriented investors demonstrated strong demand for revenue bonds, to which the Portfolio maintained an overweight versus the Index. In particular, hospital, industrial development and essential service revenue bonds were strong performers. That said, we experienced some price weakness in certain sectors, as the highest-quality sectors outperformed in the flight to quality. Overweights to prepaid natural contract bonds (bonds that guarantee a specific contract) and tobacco securitization bonds were a drag on relative returns at the end of the period.

Valuations weakened in sympathy with the troubles in the taxable corporate bond market. An underweight toward the lower-yielding and underperforming pre-refunded sector was a plus. (Pre-refunded bonds are municipal bonds that are generally backed by US Treasury bonds. In a typical pre-refunded issue, a municipality sells new bonds, using the proceeds to buy Treasury securities. It then sets those Treasury bonds aside in an escrow account that will be used to redeem the older, higher-coupon bonds either at the earliest possible date or some later date.) In addition, the pre-refunded exposure that we did hold was backed by government agencies and performed well. An overweight to the housing bond sector helped relative returns as valuations were relatively stable during rising interest rate periods.

The Portfolio maintained broad exposure across the intermediate maturity spectrum (generally two to 15 years), which was a positive as yields on longer-maturity bonds outperformed those on shorter-duration bonds. The Portfolio maintained a relatively neutral duration posture relative to the Index, although yield

Advisor's comments – concluded

curve positioning produced a modest overweight to eight- to 12-year maturities (duration is a measure of an investment's sensitivity to interest rate changes). This added to relative returns.

An emphasis on bonds with call features enhanced results, as these structures outperformed in the lower- volatility and flattening yield curve environment. However, since June, the Portfolio has held an underweight to callable structures. An overweight allocation toward BBB-rated municipal bonds enhanced results, particularly Puerto Rico general obligation and industrial development bonds. This was the case as lower-quality credits generally outperformed the highest-quality bonds, barring the flight to quality late in the reporting period.

Our allocations benefited from being overweight California and New York City general obligation bonds. Both regions benefited from strong economic and tax revenue growth, as well as rating upgrade activity. A tactical increase in Puerto Rico general obligation bonds proved to be favorable as valuations of bonds from the commonwealth stabilized. This was in response to prudent financial measures the government took in 2006 to help mitigate Puerto Rico's budgetary issues.

The Portfolio expects to continue to own high-quality credits and sectors and to take advantage of buying opportunities created by shifting market perceptions about risk. In our view, a neutral duration versus the Index and a concentration in the middle of the intermediate maturity spectrum is prudent in this higher-volatility environment. We expect that the preservation and growth of excess income should continue to be the focus of our relative value active management.

Special considerations

The Portfolio may be appropriate for long-term investors seeking high current income exempt from federal income taxes. Investors should be able to withstand short-term fluctuations in the fixed income markets in return for potentially higher returns over the long term. The yield and value of the Portfolio change every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the issuers in which the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 4.62% (before deduction of the maximum UBS PACE Select program fee; 3.06% after deduction of the maximum UBS PACE Select program fee). In comparison, the Lehman Brothers Global Aggregate Index (the "Index") (in US dollars or "USD") returned 5.74%, the Lehman Brothers Global Aggregate Ex US Index (in USD) returned 5.86% and the median return for the Lipper Global Income Funds category was 5.27%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 73. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

In the second half of 2006, government bonds rallied as fears of weaker US growth displaced concerns about inflation. The markets fluctuated due to expectations of a mild US slowdown to something more severe, and then back again. Even though the optimism that pervaded the financial markets as 2007 began was, in our view, justified given relatively strong economic data throughout much of the developed and developing world, this was not enough to prevent episodes of risk aversion. Periodic flights to quality were often triggered by concerns over the deteriorating conditions in the US housing sector. The volatility in the financial markets came to a head at the end of July, as the era of easy money seemed to come to an abrupt halt. A confluence of factors, including further losses among US mortgage lenders, the withdrawal of cheap financing for leveraged buyouts and some weak US housing market data sent a wide range of asset classe s sharply lower. In particular, the equity markets, emerging markets and the corporate bond markets sold off, while high-quality government bond prices rose.

Advisors' comments

Rogge Global Partners: Team, led by Olaf Rogge; FFTW: Team, led by David Marmon

Objective:

High total return

Investment process:

Rogge Global Partners seeks to invest the Portfolio assets it manages in bonds of issuers in financially healthy countries, because it believes that these investments produce the highest bond and currency returns over time. In deciding which bonds to buy for the Portfolio, Rogge Global Partners uses a top-down analysis to find value across countries and to forecast interest and currency-exchange rates over a one-year horizon in those countries. Rogge Global Partners also uses an optimization model to help determine country, currency and duration positions for the Portfolio. Rogge Global Partners generally sells securities that no longer meet these selection criteria or when it identifies more attractive investment opportunities, and may also sell securities to adjust the average duration of the Portfolio assets it manages.

FFTW divides the investment universe into three major blocs (the Americas, Eurozone and Asia) plus emerging markets, and analyzes in each bloc, trends in economic growth, inflation, and monetary and fiscal policies. FFTW decides which securities to buy for the Portfolio by looking for investment opportunities where its opinions on the current economic environment of a bloc or country differ from those it judges to be reflected in current market valuations. FFTW generally sells securities when it has identified more attractive investment opportunities.

Advisors' comments – continued

markets enhanced results for much of the period, although they gave back some of their gains in June and July 2007 as investors became more risk averse.

Currency allocation had a net neutral impact on performance. An underweight position in the Japanese yen versus the Danish krone and Norwegian krone, as well as certain emerging markets currencies, added value for much of the period. However, some of these gains were erased in July 2007 when the yen strengthened significantly versus other major currencies. An overexposure to dollar-bloc currencies such as the Canadian dollar detracted from performance late in 2006.

Duration selection had a positive net impact on returns (duration is a measure of an investment's sensitivity to interest rate changes). The overall portfolio duration was neutral versus the Index for much of the period, but a relatively short duration stance during the second quarter of 2007 (particularly in the Eurozone) contributed positively as bond rates moved higher.

Yield curve positioning had a negative impact on performance. This was particularly true during the fourth quarter of 2006, when short-term positions in Japan and the UK were the primary negative contributors to performance, while long yield curve positions, notably in Canada, contributed positively.

Sector and security selection had a negative impact on results. Sector selection was a detractor due primarily to our overweight in the financial sector, which was hurt by market jitters surrounding the US subprime mortgage market. Early in the period, an exposure to Japanese inflation-linked bonds also hurt performance.

FFTW

During the fiscal year, management of interest rates was a main contributor to our positive incremental returns versus the Index. In contrast, sector allocation and security selection in spread sectors (taxable bond sectors that are not Treasury securities) and our foreign exchange positioning detracted from returns.

Interest rate spread positions across Europe, the US and Asia, performed positively, particularly our underweights in European bonds versus both US and Japanese bonds. Our positions in various markets over the fiscal year followed a few key themes. First, we believed the US economy would slow only marginally, allowing the US Federal Reserve Board to remain on hold, thus keeping US interest rate policy and the yield curve relatively stable. Second, we believed that European bonds were underpricing the extent of likely rate hikes, given the region's strong economic growth. Third, we believed that long-dated Japanese government bonds offered attractive yields given the steep yield curve in Japan. When hedged back into US dollars, we felt that Japanese government bonds offered one of the more attractive carry trades available (a carry trade is a strategy whereby you borrow and pay interest in order to buy something else that has hig her interest).

During the period, we favored US mortgage securities that offered attractive yields. In particular, we built and maintained a relatively large overweight in commercial mortgage-backed securities. These issues have less interest rate sensitivity, which was attractive given our more bearish view of US Treasury bond yields. In addition, they were offering very attractive spreads relative to similarly rated corporate securities. In the beginning of 2007, rising US Treasury bonds yields, weakness in equities and concerns surrounding the US subprime housing market caused a spike in volatility. When spreads quickly widened in July and liquidity began to evaporate, our structured securities positions, including mortgage-backed, commercial mortgage-backed and asset-backed securities, underperformed.

FFTW – concluded

The currency markets proved to be challenging over the past year. At times, the US dollar failed to fall as Treasury bonds rallied and further interest rate cuts were priced into 2007. Our underweight US dollar positions versus our euro and yen positions in comparison to the Index detracted from returns, as a trendless market dominated the major currency markets for much of the period.

(Please note: After the close of the reporting period, FFTW no longer managed a portion of the Portfolio; the Portfolio will be managed solely by Rogge Global Partners. For more details, refer to page 4 of this annual report.)

Special considerations

The Portfolio may be appropriate for long-term investors seeking high total return and who are able to withstand short-term fluctuations in the fixed income markets in return for potentially higher returns over the long term. The yield and value of the Portfolio change every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the issuers in which the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan. The value of the Portfolio's investments in foreign securities may fall due to adverse political, social and economic developments abroad and due to decreases in foreign currency values relative to the US dollar. These risks are greater for investments in emerging markets than in more developed countries.

The Portfolio has agreed to repay UBS Global AM for any waived fees/reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above. Additionally, UBS Global AM and the Portfolio have entered into a written fee waiver agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees to the extent necessary to reflect the lower sub-advisory fee paid by UBS Global AM to Rogge beginning on or about August 23, 2007. UBS Global AM has agreed to reduce its management fee effective August 1, 2007, in anticipation of the lower fee rate to be paid to Rogge.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 3.96% (before deduction of the maximum UBS PACE Select program fee; 2.42% after deduction of the maximum UBS PACE Select program fee). In comparison, the Merrill Lynch Global High Yield Index (hedged in USD) (the "Index") returned 6.86%, and the median return of the Lipper High Current Yield Funds category was 6.02%. (Returns for Class A shares are also shown in the "Performance at a Glance" table on page 89. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

When we look at the period as a whole, the 12 months have been relatively good ones for the high yield market. The world economy has been strong and global high yield default rates have been at or near record lows during the period. In such a benign credit environment, riskier CCC-rated securities outperformed the overall market by more than 2.50 percentage points. The most significant gainers during the period were the large, high-profile CCC-rated credits, such as Charter Communications, Ford Motor Co., and HCA, which had started the period trading at very high yields. Given the absence of fundamental credit problems, the most significant losers were strong BB-rated issuers, such as Harrah's and Clear Channel, which were the targets of leveraged buyouts. June and July 2007 saw significant spread widening as the market posted its only losses of the year. Subprime mortgage problems and fears of a credit crunch took their toll as investors worried that these problems would spill over to the overall economy, causing high yield default rates to increase. (Subprime mortgages are granted to borrowers with lower credit profiles.) In our opinion, it is too early to tell whether these fears are justified.

Advisor's comments

Our strategic underweight in the riskiest sectors of the market detracted from relative results over the period. However, the Portfolio began to outperform the market in July 2007, as CCC-rated securities significantly underperformed the broader market for the first time during the period. At the end of July, the yield on the Portfolio was almost 80 basis points less than that of the market (a basis point is one one-hundredth of one percent). Since the market allows better credits to borrow at lower interest rates, the Portfolio's lower-than-market yield was, in our opinion, a good indicator of its better credit quality. If the current correction continues, we expect that our more conservative positioning has the potential to insulate the Portfolio from a good portion of the downdraft. It is important to remember that in previous downturns, the riskiest bonds in the market have experienced a disproportionate percentage of losses .

Objective:

Total return

Investment process:

MacKay Shields attempts to deliver attractive risk-adjusted returns by avoiding most of the unusually large losses in the high yield market, even if it means giving up much of the large gains. MacKay Shields believes that there is a very small subset of bonds that delivers outsized gains in the market. Due to the limited upside inherent in most bonds, over time, outsized gains are expected to be smaller than unusually large losses. By attempting to limit the Portfolio's participation in the extremes of the market, MacKay Shields strives to add value over a market cycle with lower volatility. MacKay Shields does this through a rigorous process that attempts to screen out what it believes to be the riskiest issuers in the market.

Advisor's comments – concluded

In addition to our overall conservative positioning, individual industry allocations also affected performance. The most significant positives were our overweight in secured airline bonds and our underweight in the auto sector, coupled with a positive bias toward Ford and General Motors. We also benefited from our purchases of healthcare company HCA after its leveraged buyout was announced. The most significant negative during the fiscal year was our overweight in energy securities, which, being relatively conservative, trailed the market. In addition, our small overweight in homebuilders detracted from results, as this industry lagged due to fears of a deepening downturn in housing. As one might expect in an expanding economic environment, there were no significant losses due to actual credit difficulties.

Manager's Note:

Overall, the Portfolio's relative performance was due to several factors, including:

•  Security selection and sector allocation (which emphasized less risky investments as opposed to many of the Portfolio's peers, which generally took more risk).

•  In comparison to its size, the Portfolio, which commenced operations in April 2006, experienced relatively large amounts of cash inflows.

•  Throughout its initial inception period, the Portfolio held more cash than it is expected to hold going forward.

•  The rapid growth of the Portfolio's assets put the Portfolio in a near-constant buying mode. As a result, the Portfolio paid the "ask" price for securities while valuing them at the "bid" price, with a compounding impact to performance; this could abate if the purchase of additional securities represents a smaller percentage of the Portfolio's assets if the Portfolio grows in the future.

Special considerations

The Portfolio may be appropriate for long-term investors seeking total return and who are able to withstand short-term fluctuations in the fixed income markets in return for potentially higher returns over the long term. The fund seeks to achieve its objective by investing primarily in a professionally managed, diversified portfolio of fixed income securities rated below investment grade or considered to be of comparable quality (commonly referred to as "junk bonds"). These securities are subject to higher risks than investment grade securities, including greater price volatility and a greater risk of loss of principal and non-payment of interest. Issuers of such securities are typically in poor financial health, and their ability to pay interest and principal is uncertain. The prices of such securities may be more vulnerable to bad economic news, or even the expectation of bad news, than higher rated or investment grade bonds a nd other fixed income securities. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the issuers in which the Portfolio invests. In addition, investments in foreign bonds involve special risks. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

Comparison of change in value of a $10,000 investment in the Class P shares of the Portfolio and the Merrill Lynch Global High Yield Index (hedged in USD)

The graph depicts the performance of UBS PACE High Yield Investments Class P shares versus the Merrill Lynch Global High Yield Index (hedged in USD) from April 30, 2006, which is the month-end after the inception date of the Class P shares, through July 31, 2007. The performance of Class A shares will vary from the performance of the class shown based on the difference in sales charges and fees paid by shareholders investing in different share classes. Past performance does not predict future performance and the performance provided does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares. It is important to note that UBS PACE High Yield Investments is a professionally managed portfolio while the Index is not available for investment and is unmanaged.

Average annual total returns for periods ended June 30, 2007, after deduction of the maximum sales charge or UBS PACE Select program fee, were as follows: Class A—1-year period, 2.71%; since inception, 1.63%; Class P—1-year period, 6.13%; since inception, 4.39%.

The annualized gross and net expense ratios, respectively, for each class of shares as in the November 30, 2006 prospectuses were as follows: Class A—2.04% and 1.35%; Class B—2.79% and 2.10%; Class C—2.54% and 1.85%; Class Y—1.79% and 1.10%; and Class P—1.90% and 1.10%. The Portfolio commenced operations on April 3, 2006. These gross ratios are estimates for the Portfolio's first fiscal year and are based on assets as of October 2006. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. UBS Global Asset Management (Americas) Inc. ("UBS Global AM") has entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees and/or reimburse the Portfolio so that the ordinary total operating expenses of each class through December 1, 2007 (exclu ding interest expense, if any) would not exceed the following: Class A—1.35%; Class B—2.10%; Class C—1.85%; Class Y—1.10%; and Class P—1.10%. The Portfolio has agreed to repay UBS Global AM for any reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above.

¹  Since inception returns are calculated as of commencement of issuance on April 10, 2006 for Class P shares and May 1, 2006 for Class A shares. The Class Y shares commenced issuance on April 3, 2006 and had been totally redeemed by July 24, 2006. Since inception returns for the Index and Lipper median are shown as of April 30, 2006, which is the month-end after the inception date of the oldest share class (Class P).

²  Maximum sales charge for Class A shares is 4.5%. Class A shares bear ongoing 12b-1 service fees.

³  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but are subject to a maximum annual UBS PACE Select program fee of 1.5% of the value of Class P shares.

If an investor sells or exchanges shares less than 90 days after purchase, a redemption fee of 1.00% of the amount sold or exchanged will be deducted at the time of the transaction, except as noted otherwise in the prospectuses.

Merrill Lynch Global High Yield Index (hedged in USD): US dollar, Canadian dollar, sterling and euro-denominated fixed rate debt of corporate issuers domiciled in an investment grade rated country (i.e., BBB or higher foreign currency long-term debt rating). Individual bonds must be rated below investment grade (i.e., BB or lower based on a composite of Moody's and S&P) but not in default; must have at least one year remaining term to maturity; a minimum face value outstanding of $100 million, C$50 million, 50 million pounds sterling, or 50 million euros; and have available price quotations. New issues qualify for inclusion after they settle.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit http://www.ubs.com.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 14.26% (before the deduction of the maximum UBS PACE Select program fee; 12.56% after the deduction of the maximum UBS PACE Select program fee). In comparison, the Russell 1000 Value Index (the "Index") returned 13.47%, and the median return of the Lipper Large-Cap Value Funds category was 13.87%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 101. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

A steep decline in crude oil prices, coupled with lower long-term interest rates and increased optimism that a Federal Reserve Board interest rate cut would be forthcoming, created the backdrop for a strong market rally in the second half of 2006. Despite generally weak economic data, investors bid up stocks and regained a sense of optimism that was lost during the previous summer's selloff. The beginning of the implosion of the subprime mortgage market negatively impacted equity performance during early 2007, but was eventually offset by news of strong US corporate earnings and a rebound in economic activity (subprime mortgages are granted to borrowers considered subprime; that is, a person with a lower credit profile). As a result, major market averages all rose strongly through May 2007. However, a sharp rise in long-term interest rates during the second quarter of 2007 had an impact on the performance of riskier assets, whil e rising crude oil prices threatened to temper consumer spending. Finally, the failure of two hedge funds in June, which was attributed to the subprime mortgage collapse, sparked a downturn in the market that was exacerbated by additional losses in other subprime lenders and housing weakness in July. A steep increase in volatility followed, leading to a dramatic fall in investor confidence and a sharp decline in the equity market in mid-July.

During the fiscal year, our portion of the Portfolio generated solid absolute results, but lagged the Index. Our investment process incorporates perspectives on valuation,

UBS PACE Select Advisors Trust – UBS PACE Large Co Value Equity Investments

Investment Advisors:

SSgA Funds Management, Inc. ("SSgA"), Institutional Capital LLC ("ICAP") and Westwood Management Corporation ("Westwood")

Portfolio Managers:

SSgA: James M. Johnson and Team;

ICAP: Team;

Westwood: Susan M. Byrne

Objective:

Capital appreciation and dividend income

Investment process:

SSgA uses several independent valuation measures to identify investment opportunities within a large-cap value universe and combines factors to produce an overall rank. Comprehensive research determines the optimal weighting of these perspectives to arrive at strategies that vary by industry. SSgA constructs the portion of the Portfolio it advises by selecting the highest-ranked stocks from the investable universe, and manages deviations from the benchmark to maximize the risk/reward trade-off. The resulting Portfolio has characteristics similar to the Russell 1000 Value Index. SSgA generally sells stocks that no longer meet its selection criteria or that it believes otherwise may adversely affect performance relative to the Index.

ICAP uses its proprietary valuation model to identify large capitalization companies that it believes offer the best relative values because they sell below the price-to-earnings ratio warranted by their prospects. ICAP looks for companies where there is a catalyst for positive change with potential to produce stock appreciation of 15% or more relative to the market over the next 12 to 18 months.

Advisors' comments – continued

quality and sentiment. These components offered mixed results for this time period. Overall, our valuation factors (price-to-earnings and cash flow) were strong, while our quality perspective and sentiment factor (a proxy for a company's earnings growth) were less successful.

Our shortfall relative to the Index was driven by stock selection decisions. The biggest detractors were the energy and healthcare sectors. Within healthcare, overweight positions in Forest Labs (-26%) and vitamin maker NBTY, Inc. (-19%) hurt Portfolio performance, with NBTY falling in June 2007 after strong 2006 performance.

Stock selection in consumer discretionary and industrial sectors helped our relative performance and minimized our losses. Within the consumer discretionary sector, Big Lots (+60.5%) and Darden Restaurants¹ (+15.5%) helped performance. Strong earnings reports were the main driver of returns. Also, during the period, Payless¹ was raised to "positive" from "neutral" by a Wall Street analyst. The company announced joint ventures with Walt Disney and Nike to develop licensed footwear collections, which is expected to help boost sales that have stagnated in recent years.

Within industrials, an overweight position in ITT Educational Services Inc. climbed 50%. Shares of the company, which provides technology-oriented post-secondary degree programs, soared to their highest price ever as fiscal first quarter net income jumped 35% and student enrollments rose 13%.

ICAP

During the fiscal year, our portion of the Portfolio outperformed the Index. Over the reporting period, stock selection was positive in consumer staples, consumer durables, energy, consumer services, financials and transportation. Our sector weightings were also positive due to our underweight in financials, overweight in technology and overweight in basic industries.

In this market environment, we saw fewer thematic opportunities for stock selection, but we have continued to find stock-specific catalysts that we believe offered compelling drivers for performance. These stock-specific catalysts can generate upward momentum for a stock, even if the external or macroeconomic environment is more challenging.

At period end, our largest sector allocation was in financial stocks, although the weight was significantly below that of the Index, and represented less than 20% of our total equity commitment. We emphasized high-quality, large-cap financial companies that we believed were less sensitive to interest rates and to the subprime mortgage situation.

Investment process (concluded)

ICAP also uses internally generated research to evaluate the financial condition and business prospects of every company it considers. ICAP monitors each stock purchased and sells the stock when its target price is achieved, the catalyst becomes inoperative, or ICAP identifies another stock with greater opportunity for appreciation.

Westwood maintains a list of securities that it believes have proven records and potential for above-average earnings growth. It considers purchasing a security on such list if Westwood's forecasted growth rates and earnings estimates exceed Wall Street expectations, or Westwood's forecasted price/earnings ratio is less than the forecasted growth rate. Westwood monitors the issuing companies and sells a stock if Westwood expects limited future price appreciation or if the projected price/earnings ratio exceeds the three-year growth rate.

Advisors' comments – concluded

At the stock level, some top performers for the reporting period were McDonald's, Hewlett-Packard, Textron, Schlumberger and Occidental Petroleum. McDonald's was sold from our portion of the Portfolio by the end of the period, as it reached its target price.

The largest detractor from performance during the period was Motorola. This stock was first added to the portfolio in the second quarter of 2006. It has not performed well due to a decline in its handset business causing profitability to suffer. Current Motorola management has undertaken a significant cost reduction plan and has reshaped the leadership and priorities of its mobile device division.

Another detractor from performance was Office Depot, the second largest company in the office products retail market. This was added to the portfolio in the second quarter of 2007. With a decline in both retail and business spending in 2007, the stock has not performed as expected. However, its management has scaled back store growth, which frees up capital which could be used for a share repurchase program.

Our exposure to high-quality securities with strong fundamentals allowed our portion of the Portfolio to outperform the Index during the reporting period. The sustainability of the global industrial cycle, which is being fueled by demand from emerging economies such as India and China, led us to identify values within the industrial segment of the market. Elsewhere, our holdings within the securities brokerage and investment management industries moved higher on the strength of asset flows into these companies. In particular, Franklin Resources, an asset manager, as well as MasterCard, Inc., which reported earnings results driven by strong transaction volumes, were top performers.

We avoided companies with direct exposure to subprime lenders, which benefited performance. Additionally, an overweight in the energy sector and strong security selection enhanced results. Some of the best-performing securities during the fiscal year included McDermott International, Exxon Mobil Corp., Marathon Oil Corp., Murphy Oil Corp. and ConocoPhillips. These companies all responded well to both the rise in the price of crude oil and to strong operating results. Strength in industrial-related sectors, such as materials and processing, contributed to relative performance. In particular, firms exposed to commodity price strength, such as Freeport-McMoRan Copper & Gold, enhanced results. The company saw its cash flow boosted by continued strength in copper prices. Another example was IPSCO, which benefited from strength in steel prices as well as from merger and acquisition activity within its industry.

In contrast, our relative performance was hindered by security selection in the healthcare sector. For example, Bristol-Myers' shares declined after it was accused of impeding the sale of a generic substitute for its best selling drug. Also, Pfizer's shares fell after the company made comments indicating that a major drug in its pipeline may experience difficulty getting approved by the Food and Drug Administration (FDA). Other detractors to performance included Motorola, which fell on weaker-than-expected handset sales.

Special considerations

The Portfolio may be appropriate for long-term investors seeking capital appreciation who are able to withstand short-term fluctuations in the equity markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

T he Portfolio has agreed to repay UBS Global AM for any reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above. Additionally, UBS Global AM and the Portfolio have entered into a written fee waiver agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees through December 1, 2007 to the extent necessary to reflect the lower overall fees paid to the Portfolio's investment advisors as a result of the lower sub-advisory fee paid by UBS Global AM to SSgA Funds Management, Inc. Finally, the Portfolio and UBS Global AM have also entered into an additional fee waiver agreement pursuant to which UBS Global AM has agreed to permanently reduce its management fee based on the Portfolio's average daily net assets to the following rate: $0 to $250 million, 0.60%; in excess of $250 million up to $500 million, 0.57%; in excess of $500 millio n up to $1 billion, 0.53%; and over $1 billion, 0.50%.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 15.76% (before the deduction of the maximum UBS PACE Select program fee; 14.04% after the deduction of the maximum UBS PACE Select program fee). In comparison, the Russell 1000 Growth Index (the "Index") returned 19.47%, and the median return for the Lipper Large-Cap Growth Funds category was 17.06%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 112. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

Large cap growth US equities began the reporting period with overall solid gains. However, these gains were offset during the latter portion of the fiscal year, as US equities were tested by a variety of headwinds. These included continued housing weakness, subprime lending woes, and the potential for a widespread "credit crunch." (Subprime lenders grant subprime mortgages to borrowers considered subprime; that is, a person with a lower credit profile.) For the 12-month period, the Russell 1000 Growth Index posted a return of 19.47%. In looking at the Index's sector-level returns, all 10 sectors recorded positive gains for the period. The strongest-performing sectors included materials (+37%), information technology (+31%), telecommunication services (+26%) and industrials (+24%). In contrast, consumer staples (+9%) and healthcare (+8%) were relatively weak performers.

Advisors' comments

Please note: Wellington Management assumed investment advisory responsibility with respect to a portion of the Fund's Portfolio in June 2007, replacing GE Asset Management. Both Advisors contributed to this commentary, covering only those periods of time during which they managed their portions of the Portfolio.

GE Asset Management

We underperformed the Index during the period of time we managed our portion of the Portfolio, from August 1, 2006 through May 31, 2007. Despite solid contributions from the consumer discretionary, staples, materials and energy sectors, our results in the technology, healthcare and industrials sectors weighed on returns. In information technology, the positive contribution from an overweight position to this

strong-performing sector was not enough to offset the negative impact of security selection during the period. While we generated positive contributions from Cisco Systems (+50.6%), eBay¹ (+35.3%) and Qualcomm (+23.3%), an underweight in computer and peripheral companies, which rallied 42.6% during the period, hurt performance. Underperformance in Molex¹ (-0.2%), Intuit (-1.2%) and Yahoo!¹ (+5.7%) also dragged on returns.

Within the healthcare sector, Amgen¹ (-19.0%) was the single largest detractor from performance. The stock suffered amid safety concerns regarding its anemia drugs and increased Food and Drug Administration (FDA) scrutiny. Although we like the strength in Amgen's therapeutics product pipeline and its long-term prospects, we reduced our weighting in the company to reflect the change in its near-term risk profile. Overweights in Lincare Holdings¹ (+15.2%), UnitedHealth (+14.6%) and Medtronic (+5.9%) also challenged performance within the healthcare sector. In addition, we underweighted cyclical industrial companies as we believe they generally lack the long-term double-digit growth we seek. However, as industrials rose +23.6% during the period, this positioning curtailed our relative performance.

On the positive side, media holdings such as Liberty Global (+68.8%), Liberty Media—Interactive (+47.1%) and Liberty Media—Capital (+38.3%) were among the best-performing stocks in the Portfolio.¹ These companies benefited due to the solid growth and the defensiveness of media compared with other consumer stocks (a defensive sector tends to remain more stable under difficult economic conditions). Underweighting the lagging consumer staples stocks also contributed positively to results. Within materials, Monsanto (+44.3%) outperformed the Index sector (+35.5%). The company, the world's biggest developer of genetically modified corn and soybeans, rallied amid speculation that it could benefit from the rise in alternative fuels, such as ethanol and bio-diesel. Finally, our energy holdings returned +21.4% versus +16.1% for the sector within the Index. This was due to our overweight and strong stock selection in energy equipment and services holdings.

Wellington Management

From the time that we started to manage a portion of the Portfolio, in June 2007 through July 31, 2007, we outperformed the Index on a relative basis.

The consumer discretionary sector was the biggest contributor to relative performance during the period, as we benefited from both an underweight to the underperforming sector and strong stock selection. Positive contributors included Apollo Group (+20.5%) and Nike (+6.6%). Additionally, stock selection within the materials sector, specifically metals and mining and chemicals, also contributed significantly to relative performance; some of our best-performing holdings here included Freeport-McMoRan Copper and Gold (+23.6%) and Agrium

Comprehensive research helps determine the optimal weighting of these perspectives to arrive at strategies that vary by industry. SSgA ranks all companies within the investable universe from top to bottom based on their relative attractiveness. SSgA constructs its portion of the Portfolio by selecting the highest-ranked stocks from the universe, and manages deviations from the benchmark to maximize the risk/reward trade-off. The Portfolio has characteristics similar to the Index. SSgA generally sells stocks that no longer meet its selection criteria or that it believes otherwise may adversely affect performance relative to the Index.

(+11.3%). Finally, an overweight to the outperforming industrials sector also added to relative performance, while stock selection was very strong in the financials sector. In particular, positive relative performance resulted both from overweights to outperforming companies, such as Invesco (+8.0%), and avoidance of underperforming names, such as American Express¹ (-6.9%) and Moody's² (-21.7%).

These returns were marginally offset by weak stock selection within the energy sector. Contributing to this were overweights to underperforming companies such as Cameco (-21.5%), and outperforming names not held in the Portfolio, such as Schlumberger¹ (+6.2%). Stock selection within the information technology sector also hurt performance, although it was partially offset by an overweight to this outperforming sector.

At the end of the reporting period, our portion of the Portfolio was positioned with overweights to the industrials, information technology, telecommunications services and materials sectors. In contrast, it held underweight positions in the consumer staples, consumer discretionary, health care, energy, utilities and financial sectors.

Marsico Capital

During the fiscal year, our portion of the Portfolio generated a positive absolute return, but lagged the Index on a relative basis. Several factors contributed to our relative underperformance. Healthcare-related companies were a major area of investment emphasis for us throughout the reporting period. Within the sector, we were adversely affected by stock selection. Biotechnology company Genentech and healthcare service provider UnitedHealth Group struggled during the period, and our large positions in these companies detracted from results.

Although our allocation to information technology increased during the year, on average, our exposure was less than half that of the Index's weighting. The limited participation in the sector negatively impacted our results, as the information technology sector of the Index soared approximately 30% during the year. In contrast, our holdings in the sector collectively returned 23%, led by a 32% gain in Cisco Systems. Stock selection in financials was a further detractor to results. Blackstone Group was the largest driver of underperformance, declining 33% for the period it was held in our portion of the Portfolio.

Stock selection in the consumer discretionary, energy and materials sectors were the primary areas of strength for our portion of the Portfolio. In particular, stock selection in the consumer services industry enhanced results. Hotel/casino operators MGM Mirage (+106%), Las Vegas Sands (+41%) and Wynn Resorts (+61%) each posted strong returns. Our energy-related positions gained 37% in aggregate, aided by a 43% gain in Schlumberger Ltd. Elsewhere, our positions in agricultural company Monsanto³ and mining company Freeport-McMoRan Copper & Gold soared 83% and 20%, respectively.

SSgA

During the fiscal year, our portion of the Portfolio generated solid absolute results, but lagged the Index. Our investment process incorporates perspectives on valuation, quality and sentiment. These components offered mixed results for this time period. Overall, our valuation factors (price-to-earnings and cash flow) were strong, while our quality perspective and sentiment factor (a proxy for earnings growth), offered less consistent results.

SSgA – concluded

Stock selection drove our performance during the period. Among the largest detractors from performance were the technology and financial sectors. Within technology, overweights to Advanced Micro Devices¹ (-49%), Lexmark International (-26%) and Motorola (-24%) hurt performance. Advanced Micro Devices started its descent in January, after Sun Microsystems announced it would use Intel's chips instead of Advanced Micro Devices', its current supplier. Just prior to this announcement, Advanced Micro Devices warned of a revenue shortfall in the fourth quarter of 2006 due to increased competition from Intel. Shares of Lexmark International, the second biggest US printer maker, fell when the company reported fiscal first quarter profit and sales that missed analysts' estimates after larger rival Hewlett-Packard Co. cut prices to win customers. Within financials, an overweight to First Marblehead¹ (-29%) and an unde rweight to strong-performing Goldman Sachs (+24%), also hurt performance. Shares of First Marblehead fell during April after two of its major clients announced a buyout of its largest competitor, SLM Corp.

The healthcare and energy sectors positively contributed to our performance return, partially offsetting losses. WellCare Health Plans, Inc. (+106%) rose over the period based on continued positive earnings expectations. Also, underweights to Amgen¹ (-22%) and Johnson & Johnson¹ (-1%) enhanced results.

Special considerations

The Portfolio may be appropriate for long-term investors seeking capital appreciation who are able to withstand short-term fluctuations in the equity markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. Also, to the extent the Portfolio invests a large portion of its assets in technology companies, the Portfolio may experience greater volatility and risk of loss due to unfavorable developments in the technology sector. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 17.86% (before the deduction of the maximum UBS PACE Select program fee; 16.10% after the deduction of the maximum UBS PACE Select program fee). In comparison, the Russell 2500 Value Index (the "Index") returned 11.09% and the median return for the Lipper Small-Cap Value Funds category was 12.24%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 122. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

Market returns during the fiscal year were strong, with large-cap stocks generally outpacing their small-cap counterparts. An early catalyst for the markets was the Federal Reserve Board's decision to stop its campaign of interest rate hikes in mid-2006. The markets continued to move higher in response to generally strong corporate earnings growth. However, recent deterioration in the credit markets has been wreaking havoc in the equity markets. It appears that several large hedge funds had invested heavily in instruments related to the subprime mortgage arena, sometimes using large amounts of leverage to enhance returns (subprime mortgages are granted to borrowers considered subprime; that is, a person with a lower credit profile). As the market turned against them, they have been selling their holdings in order to provide liquidity for debt service and client redemptions. This scenario has created tremendous volatility in the markets.

Advisors' comments

Ariel

Our patient style of investing was rewarded during the fiscal year as our portion of the Portfolio significantly outperformed the Index. Strong stock picking led us to outperform in both the rapidly rising markets through May 2007 and during the selloff over the last two months of the period, as our strategy's downside positioning for protection largely insulated our portion of the Portfolio.

Overall, strong stock picking bolstered performance. Notably, Janus Capital Group rose 86.0% due to robust

Ariel: John W. Rogers, Jr.;

Opus: Team;

MetWest Capital: Gary W. Lisenbee and Samir Sikka

Objective:

Capital appreciation

Investment process:

Ariel invests in stocks of companies that it believes are misunderstood or undervalued. It seeks to identify companies in consistent industries with distinct market niches and excellent management teams. It focuses on value stocks, which it defines as stocks with a low P/E ratio based on forward earnings and that trade at a significant discount to the private market value that Ariel calculates for each stock. Ariel generally sells stocks that cease to meet these criteria or that are at risk for fundamental deterioration.

Opus uses quantitative and qualitative analysis to construct a value-oriented portfolio of stocks that are believed to be fundamentally undervalued, financially strong, and exhibit strong earnings growth and positive earnings momentum.

MetWest Capital directly researches smaller capitalization businesses it views as "high-quality" from an objective perspective. MetWest Capital attempts to identify companies selling below intrinsic value with clear catalysts to realize full value within their investment time horizon (typically three years), and constructs a portfolio of highest conviction ideas.

fund performance, aggressive share buy-backs and strengthening asset flows. In fact, Janus-branded mutual funds recently reported positive net inflows for the first time in six years. Additionally, shares of Energizer Holdings returned 58.6% on robust battery and razor sales. Remarkably, Schick-branded shavers held market share, despite the much-anticipated launch of Gillette's new Fusion product. Energizer Holdings' management continues to offset escalating raw material costs by raising prices and improving operational efficiencies, signaling, in our opinion, that this company should keep going and going.

Conversely, a few of our holdings diminished results—in particular, our newspaper stocks. McClatchy fell 41.2% due to weak advertising trends. Though the results are disappointing, we still believe this newspaper company is attractively valued and that profits should increase as a result of cost savings achieved through the Knight Ridder integration. Also, Valassis Communications fell 29.4% after it entered into an agreement to acquire ADVO, and then sued to rescind its merger agreement based on fraud and material adverse changes. We exited out of the position after the stock rose on the announcement that Valassis had settled its dispute with ADVO and would continue with its planned acquisition.

Our economic outlook remains cautious. The markets fell in June and July, and substantial risks, in our opinion, remain. The fallout from the subprime meltdown is rippling farther than expected, and the total impact remains unknown. Also, the credit spread (or the difference between yields) between high yield "junk" bonds and US Treasury bonds nearly doubled in July, putting dozens of previously announced private equity deals in jeopardy. We believe this could signal the end of the robust merger and acquisition environment that has buoyed share prices of late. Finally, oil continues to trade in the high $70s to $80+ per barrel, and could deliver a knockout punch to the typically resilient American consumer. Despite the challenges ahead, we remain confident that our quality holdings, with well-known brands and solid balance sheets, can help to weather a market downturn.

Opus

Our portion of the Portfolio posted strong absolute and relative returns versus the Index during the fiscal year. Our outperformance was driven by excellent stock selection and underweights in the financial services and utilities sectors. In addition, excellent stock selection in the consumer discretionary, other energy, producer durables and technology sectors, as well as an overweight in the auto and transportation and materials and processing sectors, enhanced results. Our portion of the Portfolio was helped by the success of several themes put in place around the start of fiscal year, including: (1) purchasing three names in the aerospace industry ahead of a multi-year upgrade cycle in commercial and military aircraft; (2) owning hotel real estate investment trusts (REITs), which had strong yields, an improving travel climate and much lower valuations than other segments of REITs; (3) adding to technology distributors, which continued to deliver strong earnings growth while exhibiting historically low valuations early in the year; and (4) increasing our holdings in business development companies that sported low valuations, very strong yields and reputations as excellent long-term wealth generators. Our strong performance was slightly offset by poor stock selection in the auto and transportation, healthcare and materials and processing sectors. In addition, an underweight in the consumer staples and producer durables sectors detracted from results.

We continue to find values in the consumer discretionary sector, specifically in the retail industry, and expect to add to our overweight position in that sector. We have increased our weighting in the financial services

sector with the addition of two new names, but we still remain underweight versus the Index, especially in terms of regional banks and REITs. We remain overweight in the other energy sector but have repositioned our holdings by increasing our focus on exploration and production firms while reducing our exposure to contract drillers. We continue to underweight the consumer staples and utilities sectors, as we find few appealing names in those areas.

MetWest Capital

For the 12-month period, our portion of the Portfolio posted strong absolute and relative performance. As we, in our opinion, would expect from our research-driven approach, favorable stock selection was the primary source of outperformance. However, due to extremes in performance in a few segments of the market during the reporting period, our sector weightings relative to the Index also impacted results. It is important to note that the Portfolio's sector weightings are a byproduct of our bottom-up stock selection decisions, rather than reflective of a top-down view on the market.

Security selection was strong in several sectors, most notably information technology, consumer discretionary, energy and utilities. Within the information technology sector, Business Objects S.A. and Gartner were the best performers. We continue to find value in business intelligence software provider Business Objects, but sold our position in Gartner when the technology consultant's stock approached our investment team's estimate of intrinsic value. In the consumer discretionary sector, Central European Media Enterprises and United Stationers were the top contributors. We took gains and subsequently trimmed our position in Central European Media, although we feel that the international cable company's long-term prospects for growing market share and entering new markets make its stock continue to appear attractive. During the reporting period, we initiated a position in United Stationers, a wholesale distributor of business an d janitorial supplies. The company's shares appreciated as it posted solid results and continued to generate strong free cash flow. Our portion of the Portfolio also benefited from a significant underweight in financials, as that sector was the worst-performing sector for the year due primarily to subprime concerns. Also noteworthy was the fact that, over the period, acquisitions were announced for nine holdings in our portion of the Portfolio. We believe this offers further validation of both our analysts' valuation work and our commitment to investing in high-quality businesses.

Stock selection was weakest in telecommunication services, as our sole holding in that sector, Alaska's leading cable and telephone provider, General Communication, sold off during the period. However, we continue to find tremendous value in the company and continue to hold the stock. Additionally, our lack of exposure to the metals and mining sector, in particular to steel, detracted modestly from relative performance, as those industries posted sizable advances during the period.

Special considerations

The Portfolio may be appropriate for long-term investors seeking capital appreciation who are able to withstand short-term fluctuations in the equity markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan. In addition, small- and mid-cap companies are typically subject to a greater degree of change in earnings and business prospects than are larger, more established companies. Therefore, they are considered to have a higher level of volatility and risk.

The annualized gross and net expense ratios, respectively, for each class of shares as in the November 30, 2006 prospectuses were as follows: Class A—1.30% and 1.30%; Class B—2.14% and 2.14%; Class C—2.08% and 2.08%; Class Y—0.97% and 0.97%; and Class P—1.18% and 1.16%. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. UBS Global Asset Management (Americas) Inc. ("UBS Global AM") has entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees and/or reimburse the Portfolio so that the ordinary total operating expenses of each class through December 1, 2007 (excluding interest expense, if any) would not exceed the following: Class A—1.41%; Class B—2.16%; Class C—2.16%; Class Y—1.16%; and Class P—1.16%. T he Portfolio has agreed to repay UBS Global AM for any reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above.

¹  Since inception returns are calculated as of commencement of issuance on August 24, 1995 for Class P shares, November 27, 2000 for Class A and C shares, November 28, 2000 for Class B shares, and December 20, 2000 for Class Y shares. Since inception returns for the Index and Lipper median are shown as of August 31, 1995, which is the month-end after the inception date of the oldest share class (Class P).

²  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

³  Maximum contingent deferred sales charge for Class B shares is 5% imposed on redemptions and is reduced to 0% after a maximum of six years. Class B shares bear ongoing 12b-1 service and distribution fees.

⁴  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 service and distribution fees.

⁵  The Portfolio offers Class Y shares to a limited group of eligible investors, including certain qualifying retirement plans. Class Y shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees.

⁶  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but are subject to a maximum annual UBS PACE Select program fee of 1.5% of the value of Class P shares.

If an investor sells or exchanges shares less than 90 days after purchase, a redemption fee of 1.00% of the amount sold or exchanged will be deducted at the time of the transaction, except as noted otherwise in the prospectuses.

The Russell 2500 Value Index measures the performance of those Russell 2500 companies with lower price-to-book ratios and lower forecasted growth rates.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit http://www.ubs.com.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 23.28% (before deduction of the UBS PACE Select program fee; 21.44% after deduction of the maximum UBS PACE Select program fee). In comparison, the Russell 2500 Growth Index (the "Index") returned 19.88%, and the median return of the Lipper Mid-Cap Growth Funds category was 22.08%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 133. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

The equity market for small- and mid-cap growth stocks recovered from its mid-2006 malaise to post a very meaningful advance during the 12 months ended July 31, 2007. In effect, substantially all of the return reported for the US market in calendar year 2006 was attributable to the final five months of the year when crude oil prices retreated from approximately $74 to $58 per barrel. As inflationary expectations began to decline, investors began factoring the potential for a reduction in short-term interest rates, providing equity investors with a more positive outlook. Investor confidence prevailed until credit spreads began to widen in June 2007, when concerns surfaced that hedge funds, with their leveraged mortgage securities portfolios, would need to dramatically mark down their portfolio valuations to more fully reflect their risks. A growing aversion to risk then led to concerns over the sustainability of economic growth i n an environment of shrinking liquidity and heightened concerns over credit quality. As this reporting period came to a close, volatility returned, with several of the major stock indexes hitting all time highs and then promptly retreating with several dramatic selloffs.

Advisors' comments

Please note: Effective March 1, 2007, Delaware Management Company ("Delaware") was replaced by Copper Rock as one of three Advisors to the Portfolio. Both Advisors (Delaware and Copper Rock) provided commentary for this report. Additionally, ForstmannLeff LLC changed its name to AG Asset Management LLC.

Portfolio Managers:

Copper Rock: Tucker Walsh, Michael Malouf and Team

AG Asset Management: Team, led by Beth Dater and Sammy Oh

Riverbridge: Team, led by Mark Thompson

Objective:

Capital appreciation

Investment process:

Copper Rock employs a fundamental, bottom-up investment approach that focuses on identifying emerging companies that exhibit the potential for strong and sustainable revenue growth over each of the following two years. Copper Rock utilizes a "pure" growth investment style that emphasizes growth and momentum characteristics. Copper Rock attempts to manage risk by diversifying and understanding its holdings and employing a stringent sell discipline.

AG Asset Management seeks fundamentally strong and dynamic small- and mid-cap companies that are trading at a discount to their growth rates. AG Asset Management's goal is to ascertain a dynamic of growth before it manifests in consensus estimates. AG Asset Management believes that it can be successful because it views the small- and mid-cap market to be inherently less efficient than the large-cap market.

During the period in which we managed a portion of the Portfolio, from August 1, 2006 through February 28, 2007, our performance underperformed the Index. Over this period, both stock selection and sector allocation were slightly negative. Strong contributions in stock selection from the consumer non-durables, financials, and energy sectors were offset by the weakness among our technology and healthcare stocks. An underweight in the consumer durables sector, the top-performing sector in the Index for the period, was the main contributor to the Portfolio's slight underperformance.

Among individual stocks, top contributors were well-diversified. The biggest contributor to performance was specialty metals manufacturer Allegheny Technologies,¹ as it rose over 60% on strong revenue and earnings growth. Wynn Resorts¹ continued to perform well, up over 63% on investor reaction to the strength of its newly opened casino in Macau and its announcement of a special dividend issue. Shares of sporting goods retailer Hibbett Sports¹ were up over 57% in response to strong sales and earnings growth driven by a resurgence in consumer spending.

Contributing significantly to the disappointing results from the healthcare sector was biotech firm Telik, Inc.,¹ which fell 65% for the period after disclosing inconclusive results in one of its developmental drug trials due to poor trial management. Subsequently, we eliminated it from our portion of the Portfolio. Shares of Microsemi Corp.¹ fell over 19% after the company lowered its fourth quarter 2006 guidance due to general weakness in the semiconductor market, while shares of online weight loss company NutriSystem¹ slid over 26% for the period, as investors responded negatively to news regarding increased marketing and customer acquisition costs.

Copper Rock

In the time since we assumed advisor responsibilities on March 1, 2007, through period end on July 31, 2007, our portion of the Portfolio significantly outperformed the Index. Stock selection in the technology, producer durables, consumer discretionary and financial services sectors contributed the most to performance. However, stock selection in healthcare, materials and processing and utilities detracted from performance. In addition, an underweight position in the materials and processing sector detracted from results.

Investment process (concluded)

Riverbridge believes that earnings power determines the value of a franchise. Riverbridge focuses on companies that are viewed as building their earnings power and building the intrinsic value of the company over long periods of time. Riverbridge looks to invest in high-quality growth companies that demonstrate the ability to sustain strong secular earnings growth, regardless of overall economic conditions.

Among the technology holdings that contributed to performance during the period were Riverbed Technology, a developer of proprietary software that enhances and speeds up virtual networks, and Commscope,¹ a provider of cabling and connectivity solutions for communications networks and service providers. We believe Riverbed Technology is poised for continued growth as networks must become increasingly powerful to support demand for video and voiceover Internet capabilities. The majority of Commscope's business is focused on providing cable services for communications infrastructure. During the period, the company benefited from high demand in the expansion of cable/broadband networks and its ability to raise prices for the first time in six years. This pricing power was largely a result of the continually increasing demand for enabling video over the Internet.

Also during the period, oil exploration tools provider Dresser-Rand contributed to performance. The company has reacted positively to excitement around the global energy infrastructure build-out. After the first quarter of 2007, expectations for Dresser-Rand were raised, and the outlook has improved even more as the backlog for energy infrastructure has continued to expand.

On the downside, the healthcare sector proved more challenging for our investment strategy during the period. The uncertainty of the pending change in the White House has ignited concerns about healthcare reform, making the environment particularly difficult for the services companies we tend to favor, which typically generate high free cash flow and recurring revenues. We also like pharmaceutical and medical device companies with new products in the late stages of development. However, we do not tend to participate in early stage biotech companies due to the high level of risk. During the reporting period, both service companies and late stage pharmaceutical/medical devices were out of favor with the market.

Riverbridge

During the review period, our portion of the Portfolio significantly outperformed the Index, driven primarily by stock selection. Echelon, a pioneer in control networks, was the top-performing stock; it showed strength after announcing significant new client agreements, and appears to be gaining adoption of its core technology. Chemed also posted robust returns over this time period. Strong quarterly earnings reports and increased earnings guidance propelled its stock price higher. We also received a short-term benefit from the acquisition of a few of our holdings. These included WebEx Communications,¹ which was acquired by Cisco Systems,¹ and medical technology provider Kyphon, which announced that it would be acquired by Medtronic.¹

From a sector perspective, we benefited from stock picking in the healthcare sector, as our holdings significantly outperformed those contained in the Index. We also benefited from both stock picking and an overweight position in the information technology sector. Conversely, our stock picking in the consumer staples sector hindered performance relative to the Index.

We have positioned our portion of the Portfolio to continue to focus on identifying and holding those companies that we believe possess the ability to sustain their earnings growth regardless of the economic environment. Our portion of the Portfolio contains companies that have very little debt on their balance sheets, and are expected to be capable of internally financing their future growth. Consequently, we do not believe the holdings in our portion of the Portfolio will be as vulnerable as many other companies who are borrowing or raising capital to grow their businesses.

Advisors' comments – concluded

AG Asset Management

Our portion of the Portfolio generated strong results during the reporting period, and outpaced the Index. This performance was driven by good stock selection in several economic sectors, not by any dramatic overweights or underweights in any particular sector.

General Cable, a manufacturer of heavy duty cables for energy and communication transmissions, was our best performer during the period. The company is benefiting from increased global sales, acquisition of a European competitor and burgeoning demand for its products, as developing countries seek to build out their infrastructure. In addition, more developed countries are undertaking upgrades to their national electricity grids. Several other companies in the producer durables sector, such as BE Aerospace, Bucyrus and Middleby also produced significant gains, as investors began to recognize the substantial long-term growth opportunities available to these companies.

Over the past 12 months, our portion of the Portfolio's largest sector allocation was in the consumer discretionary sector, where companies such as Activision, Vail Resorts, GameStop and Penn National Gaming posted strong advances. While our holdings in this sector outperformed the sector in the Index, we did experience disappointing results from holdings such as Chemed² and Bebe Stores, both of which were subsequently sold from our portion of the Portfolio. Our second-largest allocation was comprised of companies in the technology sector. Holdings that advanced sharply included Equinix, Nuance Communications, Varian Semiconductor¹ and RF Microdevices.¹ However, within the technology sector, holdings such as ACI Worldwide, DivX and Ariba detracted from results as their share prices retreated due to lack of visibility in earnings growth.

Although our portion of the Portfolio underperformed the Index in both the energy and healthcare sectors, strong advances were made by Denbury Resources and Carrizo Oil & Gas in energy, and by I-Flow and West Pharmaceutical in healthcare. We continue to believe investment success should be derived more from the early identification of small and dynamic companies that are growing, as opposed to positioning for macroeconomic themes that can prove very difficult to accurately predict. As always, we are devoting our efforts to identifying those companies that appear poised to achieve growth in excess of the consensus expectations. Our portion of the Portfolio remains broadly diversified at the sector level, as well as among its individual holdings. We continue to emphasize companies that have good visibility on their growth prospects and have actual earnings in their projections.

Special considerations

The Portfolio may be appropriate for long-term investors seeking capital appreciation who are able to withstand short-term fluctuations in the equity markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan. In addition, small- and mid-cap companies are typically subject to a greater degree of change in earnings and business prospects than are larger, more established companies. Therefore, they are considered to have a higher level of volatility and risk. Also, to the extent the Portfolio invests a large portion of its assets in technology companies, the Portfolio may experience greater volatility and risk of loss due to unfavorable developments in the technology sector.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 24.48% (before the deduction of the maximum UBS PACE Select program fee; 22.63% after the deduction of the maximum UBS PACE Select program fee). In comparison, the MSCI Europe, Australasia, Far East Free Index (net LU) (in US dollars) (the "Index") returned 23.84%, and the median return for the Lipper International Large-Cap Growth Funds category was 23.13%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 144. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

The international equity markets performed very strongly during the fiscal year, with the Index returning 23.84%. Many European markets performed well, especially Germany and the Scandinavian countries. Switzerland, in contrast to last year, when it was the best performing of the larger European markets, was this reporting period's second worst-performing market. The worst performing market was Japan, which rose just 7.7%. Other Pacific markets were very strong, with New Zealand returning 48.7%, and Singapore, the strongest market, up 61.9%.

As with last year, the materials sector generated the strongest results, up 40.9%, followed by the telecommunications sector, which was up 31.7%. In contrast, healthcare proved to be the weakest sector, up just 1.9%. Currencies were generally strong against the dollar. Higher interest rate currencies such as the New Zealand and Australian dollars tended to be very strong, whereas the yen, at the lower end of the interest rate spectrum, was weak, falling 0.7%.

Advisors' comments

Martin Currie

Our portion of the Portfolio outperformed the Index during the fiscal year, as stock selection in every region except Japan contributed to results. We are currently emphasizing stocks in the materials, financials and industrials sectors—some of the strongest performing sectors during the reporting period. In addition, our limited exposure to the healthcare sector benefited

Investment process:

Martin Currie is an experienced international equity manager. The firm has a highly active "conviction" approach, seeking the best opportunities for growth across global stock markets. Martin Currie identifies "change" as the central dynamic behind stock price movement. This means recognizing change at the company level (management changes, product strategies, acquisitions, etc.) and at the macro level (legislative changes, economic prospects, sector dynamics, etc.). Determining the impact of these changes may lead to outperformance. Its investment process allows Martin Currie to identify, evaluate and exploit change at an early stage in clients' portfolios. In managing its segment of the Portfolio's assets, Martin Currie uses a fully integrated international investment process. So rather than running distinct regional portfolios, it compares and rank s stock opportunities across the whole investment universe. To help identify and evaluate the best stock ideas, Martin Currie employs fundamental company and sector research, together with its own proprietary quantitative screening tool, the Dynamic Stock Matrix^TM. The result is a committed

performance. On a regional basis, our emerging markets exposure enhanced our results.

First and foremost, however, we are stock pickers, assembling a focused portfolio of high-conviction stocks. Holdings in ABB (power transmission and distribution equipment), Siemens (an industrial conglomerate) and Tecnicas Reunidas (an engineering contractor that specializes in constructing refineries and power plants) produced particularly strong returns over the period. We also enjoyed strong contributions from Fiat and Zinifex.

In the financials sector, we benefited from the rapid pace of corporate buyout activity. For example, our investment in ABN AMRO occurred just before a bidding war broke out between Barclays and a consortium of European banks. In addition, select holdings in the Hong Kong exchanges rose thanks to continuing financial deregulation in China. In the utilities sector, the ongoing liberalization of European electricity markets helped to drive returns. Electricity producers such as France's EDF are benefiting as national energy prices move towards the European average. Nicolas Sarkozy's victory in the French presidential election also boosted sentiment towards EDF.

On the whole, our Japanese positions tended to underperform those in the Index. The Japanese yen's weakness relative to the euro and British pound weighed on holdings such as Sumitomo Mitsui Financial and Orix. Furthermore, the Japanese market was led by higher yielding sectors for much of the fiscal year, such as steel, oil, real estate and wholesale traders. Our portion of the Portfolio had very limited exposure to these sectors. Instead, our Japanese holdings emphasized those geared toward robust capital expenditure, the housing market and the reflation of the Japanese economy. With concerns persisting as to the durability of the Japanese recovery, stocks exposed to these areas underperformed.

and distinctive EAFE (that is, Europe, Australasia, Far East) portfolio that reflects what Martin Currie believes are the best investment opportunities internationally.

Mondrian conducts research on a global basis in an effort to identify securities that have the potential for long-term total return. The center of the research effort is a value-oriented dividend discount methodology toward individual securities and market analysis that attempts to identify value across country boundaries. This approach focuses on future anticipated dividends, and discounts the value of those dividends back to what they would be worth if they were being paid today. Comparisons of the values of different possible investments are then made. In an international portfolio, currency returns can be an integral component of an investment's total return. Mondrian uses a purchasing power parity approach to assess the value of individual currencies. Purchasing power parity attempts to identify the amount of goods and services that a dollar will buy in the United States, and compares that to the amount of a foreign currency required to buy the same amount of goods and services in another country.

JP Morgan manages its segment of the Portfolio's assets using a bottom-up, research-driven strategy that seeks to generate risk characteristics that closely match those of the benchmark, yet at the same time capitalize on the information advantage created by the firm's proprietary research capabilities to generate outperformance. The strategy is driven by valuation-based fundamental analysis, focused on normalized earnings and earnings growth. The team seeks to maintain regional weights and sector/industry weights close to those of the benchmark. Stock selection is the focus, being the expected primary source of added value.

JPMorgan

During the reporting period our portion of the Portfolio generated strong results, outperforming the Index. From a sector perspective, basic industries and capital markets banks contributed positively to returns, while property and telecoms detracted from performance. Regionally, Continental Europe and Japan aided returns, while the UK and the Pacific Rim detracted from results.

From a stock-specific standpoint, Orkla, Norway's largest producer of consumer goods, was the largest contributor to performance, as the company continued to generate strong earnings. Profits rose a better-than-expected 61% year-over-year in the first quarter of 2007, following an 11% increase in revenues. In addition, Orkla benefited from the disposal of real estate and media interests. This follows a 58% year-over-year increase in fourth-quarter 2006 earnings. Additionally, Air France-KLM,¹ Europe's largest airline, performed well following a 70% increase in fiscal first-quarter profits. The increase was attributed to strong passenger demand, as well as to positive cost savings related to the merger.

On the downside, Obayashi Corp.,¹ one of Japan's largest contractors, was the worst performing stock in our portion of the Portfolio. The company was targeted for a bid-rigging scandal in the midst of corruption within the Japanese construction industry. As a result, the CEO resigned and three mid-ranked officials were arrested for price fixing. Elsewhere, an underweight to DaimlerChrysler, the German automaker, hurt performance. Shares of the company surged on word that it was considering selling off its unprofitable Chrysler unit. Then, in late March, the company received an offer for Chrysler from a group led by Magna International.

Mondrian

Our portion of the Portfolio outperformed the Index during the fiscal year, with market and currency selection contributing positively to performance. The market weights in the Pacific region were especially positive, as an underweight position in the weak Japanese market was beneficial, and overweight positions in the outperforming markets of Australia, New Zealand and Singapore enhanced results. A non-index position in South Korea was also beneficial since this market performed strongly.

Overall stock selection did not contribute positively to relative performance. While we saw good results in France, Spain and Japan, we did not see good results in Australia, Hong Kong and Germany. Restructuring benefits helped propel GKN, a UK engineering stock, up 67.7%. Iberdrola, a Spanish electric utility, rose 62.4% following merger and acquisition activity (real and rumored) in the Spanish utility sector. Strong European construction and new, more proactive management at Saint-Gobain, a French buildings materials company, helped the stock rise by 60.6%. In contrast, GlaxoSmithKline, a UK pharmaceuticals company, was down 4.2%, reflecting its sector's poor performance during the fiscal year. Another weak stock was Millea, a Japanese insurance company that was up by 2.8%, partly due to losses following typhoons in Japan last year. Underweight positions in the outperforming materials and industrial sectors were not favorable , but an overweight position in the outperforming telecommunications sector was a positive.

Advisors' comments – concluded

The portfolio's defensive hedge against the British pound did not have a beneficial effect on performance, as sterling rose against the US dollar (+8.8%). Underweight positions in the underperforming Japanese yen (-3.9%) and Swiss franc (+2.3%) were beneficial, as were overweight positions in the outperforming Australian (+11.8%) and New Zealand dollars (+24.7%).

Special considerations

The Portfolio may be appropriate for long-term investors seeking capital appreciation who are able to withstand short-term fluctuations in the equity markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan. The value of the Portfolio's investments in foreign securities may fall due to adverse political, social, and economic developments abroad and due to decreases in foreign currency values relative to the US dollar. These risks are greater for investments in emerging market issuers than for issuers in more developed countries.

T he Portfolio has agreed to repay UBS Global AM for any reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above.

¹  Since inception returns are calculated as of commencement of issuance on August 24, 1995 for Class P shares, November 27, 2000 for Class A, B, and C shares and January 17, 2001 for Class Y shares. Since inception returns for the Index and Lipper median are shown as of August 31, 1995, which is the month-end after the inception date of the oldest share class (Class P).

²  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

³  Maximum contingent deferred sales charge for Class B shares is 5% imposed on redemptions and is reduced to 0% after a maximum of six years. Class B shares bear ongoing 12b-1 service and distribution fees.

⁴  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 service and distribution fees.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.

Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit http://www.ubs.com.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 49.31% (before the deduction of the maximum UBS PACE Select program fee; 47.09% after the deduction of the maximum UBS PACE Select program fee). In comparison, the MSCI Emerging Markets Free (EMF) Index (the "Index") returned 50.94% and the median return of the Lipper Emerging Markets Funds category was 48.60%. (Returns for all share classes over various time periods are shown in the "Performance at a Glance" table on page 159. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

Equities in emerging markets enjoyed strong performance, fueled by buoyant international trading flows, stronger-than-expected growth data and merger and acquisition activity. This propelled many of the major emerging markets equity indexes to record levels in early 2007. Growth accelerated in China reaching 11.9% in the second quarter of 2007, despite monetary tightening. The Indian economy also achieved a growth rate in excess of 9%. The demands of these economies offered support for commodity prices, including metals like zinc and nickel. This, in turn, proved beneficial for markets across the resource-rich Latin American region. Evaluations of emerging markets equities are based on a perception of reduced risk, as many governments are reporting current account surpluses along with commitments to increase investment in infrastructure. At the same time, internal demand is encouraging the development of more sophisticated consu mer markets. In 2007, there was debate over how far emerging markets could deviate from US growth, but investors became increasingly alert to the potential for contagion from the US subprime mortgage market toward the end of the review period.

Advisors' comments

Gartmore Global Partners

Our portion of the Portfolio handily outperformed the Index during the fiscal year. This was primarily due to strong stock selection. For example, our overweight position in Indian mobile company Bharti Airtel enhanced results. India is the world's fastest growing mobile phone market, and Bharti Airtel is enjoying

Portfolio Managers:

GGP: Christopher Palmer

Mondrian: Team

Objective:

Capital appreciation.

Investment process:

GGP seeks to identify and quantify unexpected earnings. This process is driven by a disciplined and consistent investment philosophy that allows GGP to identify those companies that GGP believes will deliver positive earnings growth that will likely exceed or be sustained beyond consensus expectations. To find these opportunities, GGP uses top-down and bottom-up fundamental analysis. GGP also uses portfolio monitoring to manage the risk spectrum at the stock, sector, country and portfolio level. GGP generally sells a security that it believes no longer has the potential for above-consensus earnings.

Mondrian conducts research on a global basis in an effort to identify securities that have the potential for long-term total return. The center of the research effort is a value-oriented dividend discount methodology toward individual securities and market analysis that identifies value across country boundaries. This approach focuses on future anticipated dividends, and discounts the value of those dividends back to what they would be worth if they were being paid today. Comparisons of the values of different possible investments are then made. In an international portfolio,

robust growth of its subscriber base. Increasing exposure to Chinese cement maker Anhui Conch also proved effective. Its shares have been supported by booming demand for construction products, as well as a positive perception of the company's prospects as a key regional player during a time of consolidation. Exposure to Chinese property developer Shimao Property also added value, as the company has a holding in a significant land bank. (A land bank is an entity that purchases and retains potential development plots.)

Less successful positions included an overweight in Russian energy company Surgutneftegaz. In Russia, the energy sector as a whole has suffered from underinvestment, and has been undermined by President Putin's stance on the possible re-nationalization of assets. Finally we exited from Nan Ya Printed Circuit Board in early 2007, which was a detractor from performance due to overcapacity in the chip market and concerns about prospects for a major outsourcing contract.

At the country level, our investment strategy was particularly successful in Russia. We maintained an underweight position in energy company Gazprom, which was negatively affected by the declining price of oil for much of the period. We benefited from an overweight in the country's largest lender, Sberbank. Its share price gained after President Putin lifted ownership limits on Russian banking stocks. Our overweight in China also proved to be highly successful when more evidence emerged of China's rapidly expanding economy, and its equity market moved up to record levels. Our least successful country-level strategy was our underweight exposure to Peru, where the surge in demand for mining products, such as copper, has given its market additional momentum.

Mondrian Investment Partners

Our portion of the Portfolio underperformed the Index during the fiscal year. This was primarily due to disappointing results from stock selection and market positioning. At the market level, performance was negatively impacted by an underweight exposure to the strong returns of the Chinese market and overweight positions in the less buoyant markets of Thailand and Taiwan. This was partially offset by the positive impact of an underweight position in the weak Russian market, and an overweight exposure to Malaysia, which performed well during the fiscal year. At the sector level, our portion of the Portfolio benefited from overweight positions in the telecommunications and financials sectors. In addition, an underweight to the energy sector was helpful as it underperformed despite the continuing strength in oil prices.

Investment process (concluded)

currency returns can be an integral component of an investment's total return. Mondrian uses a purchasing power parity approach to assess the value of individual currencies. Purchasing power parity attempts to identify the amount of goods and services that a dollar will buy in the United States, and compares that to the amount of a foreign currency required to buy the same amount of goods and services in another country.

Advisors' comments – concluded

In terms of stock selection, the positive contributions from holdings in Russia, Brazil and Hungary were more than offset by the negative impact of selections in Korea, Taiwan and India. In Korea, auto manufacturer Hyundai Motor and technology firm Samsung Electronics both generated poor results. In the banking sector, our positions in Kookmin Bank and Hana Financial detracted from results. Financial stocks in Taiwan also underperformed during the year; our holding in Mega Financial hurt returns, while the defensive stock Chunghwa Telecom also performed poorly in a rising market environment. On the positive side, rising prices for steel and other raw materials directly benefited holdings in steel makers Evraz Group (Russia) and CSN (Brazil), and the Brazilian diversified mining group CVRD. Other holdings in Russia also performed well, notably gas producer Novatek¹ and telecommunications provider Mobile Telesystems.

Special considerations

The Portfolio may be appropriate for long-term investors seeking capital appreciation who are able to withstand short-term fluctuations in the equity markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities the Portfolio invests. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan. The value of the Portfolio's investments in foreign securities may fall due to adverse political, social, and economic developments abroad and due to decreases in foreign currency values relative to the US dollar. These risks are greater for investments in emerging market issuers than for issuers in more developed countries.

Comparison of change in value of a $10,000 investment in the Class P shares of the Portfolio and the MSCI Emerging Markets Free (EMF) Index

The graph depicts the performance of UBS PACE International Emerging Markets Equity Investments Class P shares versus the MSCI Emerging Markets Free (EMF) Index over the 10 years ended July 31, 2007. (The composition of the MSCI EMF Index, like many indexes, may change from time to time. For example, at one point Malaysia was excluded from the Index, but as of July 31, 2001, was included.) The performance of the other classes will vary from the performance of the class shown based on the difference in sales charges and fees paid by shareholders investing in different share classes. Past performance does not predict future performance and the performance provided does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares. It is important to note that UBS PACE International Emerging Markets Equity Investments is a professionally managed portfolio while the Index is not available for investment and is unmanaged.

A note about UBS PACE Global Real Estate
Portfolio's shareholder letter

UBS PACE Global Real Estate Portfolio was first made available to investors on November 30, 2006, via Class Y shares. Since that time, Class Y shares are no longer outstanding, and additional share classes were sold. Therefore, for purposes of reporting on performance, this letter references the Portfolio's next oldest share class, Class A, which were first issued on December 18, 2006, as well as its Class P shares, which were first sold on January 22, 2007. The Advisor's comments, however, reflect the events and positioning of the Portfolio for the period since the Fund's inception date on November 30, 2006.

Performance

Since their first issuance on December 18, 2006 through July 31, 2007, the Portfolio's Class A shares declined 2.63% (before deduction of the maximum Class A sales charge; the shares declined 7.96% after deduction of the maximum Class A sales charge).

For the period since their first issuance on January 22, 2007 through July 31, 2007, the Portfolio's Class P shares declined 6.82% (before deduction of the maximum UBS PACE Select program fee; the shares declined 7.56% after the deduction of the maximum UBS PACE Select program fee.

In comparison, the FTSE NAREIT Equity Index (in USD) (the "Index") declined 13.23% and the FTSE EPRA/NAREIT Global Real Estate Index declined 4.95%, while the Lipper Real Estate Funds median declined 13.19%. These numbers reflect the returns generated by the Indexes and the median from December 31, 2006—the closest month-end after the inception date of the Fund's Class A shares—through July 31, 2007. (Returns for all share classes since inception and descriptions of the Indexes are shown in the "Performance at a Glance" table on page 171. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

The US real estate investment trust (REIT) market peaked in early February, around the time of the Blackstone/Equity Office Properties transaction (which made Blackstone the landlord overseeing one of the US's most impressive real estate portfolios). Since then, the market has meaningfully declined. Volatility drivers were interest rate concerns and, in the case of the US, widening credit spreads that migrated from issues in the subprime market. Subprime mortgages are granted to borrowers considered subprime; that is, a person with a lower credit profile. Consequently, much private equity activity exited the market, which had

Team, led by Mark Howard-Johnson and David Kruth, co-managers

Objective:

Total return

Investment process:

The Portfolio invests primarily in real estate investment trusts (REITs) and other real estate related securities. The Portfolio can take advantage of what it believes to be attractive opportunities in both developed and emerging markets around the world.

GSAM conducts fundamental, bottom-up research seeking to identify undervalued, well-managed businesses with strong growth potential that offer an attractive level of income and capital appreciation. The GSAM team combines bottom-up research with proprietary valuation models that analyze the local property and equity markets, and it then compares valuations across regions and property types. Both the bottom-up research and the proprietary valuation models are used to formulate forward-looking, risk-adjusted return expectations for markets across the globe.

Market review – continued

a particularly negative impact in US REITs. Although the US and the UK declined meaningfully over the reporting period, all other regions generated positive results, especially the emerging markets. Even in the US and UK, there has been little indication that private equity market pricing is softening. Given firm private market pricing, combined with the recent sell-off on the public side, US REITs are now trading at more than a 20% discount to their net asset value (NAV), and UK REITs are trading at a 25% discount to their NAV. As a result, many REITs have announced share buy-back programs; a testament to management's view that their own stock is cheap.

Although negative sentiment may impact the markets over the near term, many of the factors supporting the US market over the long term are also apparent in other geographic regions. These include growing economies, benign interest rates that are low in historical terms, strong fundamentals and robust capital flows. We believe the non-US real estate securities market is further supported by favorable structural change (post adoption of the REIT structure which was designed to provide a similar structure for investment in real estate, as mutual funds provide for investment in stocks), greater inefficiencies and numerous markets in the earlier stages of a fundamental recovery.

Advisor's comments

Since its inception, the Portfolio benefited from positive stock selection in Australia (Valad Property Group), Japan (Japan Excellent), the UK (Great Portland Estates), the US (Simon Property Group) and Hong Kong (Kerry Properties). In addition, the Portfolio experienced positive country selection in China, Brazil, Mexico and Canada. A meaningful detractor from performance was the Portfolio's high cash position on the day of its funding when the US market appreciated 1.0%. Additionally, stock selection in Singapore and country selection with respect to Hong Kong and Japan detracted from performance.

China's notable appreciation was largely attributable to its economy's exceptionally strong growth and the announced austerity measures that were deemed less restrictive than expected. Fundamentals remain very strong, particularly on the mid-tier housing development side. Hong Kong is further along in its fundamental recovery than other Asian markets and it continues to show strong occupancy and rental growth. We continue to focus on those companies that have solid management teams, strong balance sheets, development expertise and meaningful exposure to China.

Singapore's property market is extremely buoyant across all sectors. The luxury home market is enjoying strong demand and prices continue to surprise on the upside. Office demand remains strong and new supply should be constrained, at least through 2009. Consequently, vacancy is now estimated to be less than 1% and year-over-year rents are increasing 20% to 30%. We maintain an overweight position to the region and to those companies that have a development orientation or are focused on the office sector.

Expectations for a sustainable economic recovery and asset price inflation continue to support fundamentals in Japan. Japanese REITs that are especially focused on the office sector continue to see the strongest earnings acceleration, with demand for top-tier office space now working its way down to the next tier. Stock selection was positive given our overweight positions in Japan Excellent and New City Residence.

In Australia, fundamentals continue to improve across all sectors, driven by strong economic growth and reasonable demand and supply dynamics. In addition, merger and acquisition (M&A) activity remains robust. Stock selection was positive for the reporting period, with overweight positions in Valad Property Group and Investa.¹ In France, fundamentals remain strong, particularly in the Paris office market where supply is limited and rents are rising. In the UK, with vacancy rates less than 4% in central London and 2% in London's West End, fundamentals remain very robust. Throughout the recent decline in the REIT market, we

opportunistically increased our weightings in our higher conviction stocks. These included Great Portland Estates, which has significant redevelopment opportunities in the West-End office market, and Minerva, a developer of office and regional mall assets in London. Although Germany's performance has been disappointing, market conditions are currently far more favorable than in the past few years, potentially indicating that rent increases may be on the horizon.

The emerging property markets were very strong during the reporting period, with China, Mexico and Brazil outperforming all developed property markets. We continue to leverage our team to identify property management names such as Urbi, a Mexican homebuilder, capitalizing on increased homeownership and expansion of the mortgage market, and BR Malls, a Brazilian high-end regional mall owner expected to capitalize on favorable consumer trends. Our most recent additions to the Portfolio were Agile Property, a Hong Kong-listed company focused in China; Robinson's Land in the Philippines, which is a play on the fundamental recovery of office and retail markets where rents and occupancies are increasing; and China Central Properties, which offers a unique business model focused on distressed properties and, in our view, has a strong management team.

Special considerations

The Portfolio may be appropriate for long-term investors seeking to diversify a portion of their assets into real-estate related investments. Investors should be willing to withstand short-term fluctuations in the equity and real estate markets in return for potentially higher returns over the long term. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies or issuers in whose securities the Portfolio invests. The value of the Portfolio's investments in foreign securities may fall due to adverse political, social, and economic developments abroad and due to decreases in foreign currency values relative to the US dollar. These risks are greater for investments in emerging market issuers than for issuers in more developed countries. There are certain risks a ssociated with investing in real estate-related investments, including sensitivity to economic downturns, interest rates, declines in property values and variation in property management.

Total returns for periods ended June 30, 2007, after deduction of the maximum sales charge or UBS PACE Select program fee, were as follows: Class A—since inception, -3.72%; Class C—since inception, 0.32%; Class P—since inception, -3.28%.

The annualized gross and net expense ratios, respectively, for each class of shares as in the November 30, 2006 prospectuses were as follows: Class A—2.04% and 1.45%; Class C—2.79% and 2.20%; Class Y—1.79% and 1.20%; and Class P—1.79% and 1.20%. The Portfolio commenced operations on November 30, 2006 and these gross ratios are based on an estimated $25 million in assets under management for the Portfolio's first fiscal year. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. UBS Global Asset Management (Americas) Inc. ("UBS Global AM") has entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees and/or reimburse the Portfolio so that the ordinary total operating expenses of each class through December 1, 2007 (excluding dividend e xpense, borrowing costs and interest expense, if any) would not exceed the following: Class A—1.45%; Class C—2.20%; Class Y—1.20%; and Class P—1.20%. The Portfolio has agreed to repay UBS Global AM for any reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above.

¹  Since inception returns are calculated as of commencement of issuance on December 18, 2006 for Class A and C shares, and January 22, 2007 for Class P shares. The Class Y shares commenced issuance on November 30, 2006 and had been totally redeemed by February 16, 2007. Since inception returns for the Indexes and Lipper median are shown as of December 31, 2006, which is the month-end after the inception date of the oldest share classes (Class A & Class C).

²  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

³  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 service and distribution fees.

⁴  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but are subject to a maximum annual UBS PACE Select program fee of 1.5% of the value of Class P shares.

If an investor sells or exchanges shares less than 90 days after purchase, a redemption fee of 1.00% of the amount sold or exchanged will be deducted at the time of the transaction, except as noted otherwise in the prospectuses.

Performance

For the 12 months ended July 31, 2007, the Portfolio's Class P shares returned 14.38% (before deduction of the maximum UBS PACE Select program fee; the shares returned 12.67% after deduction of the maximum UBS PACE Select program fee). In comparison, the Merrill Lynch US Treasury 1-5 Year Index, the MSCI World Free Index (net US) and the Consumer Price Index returned 5.47%, 20.45% and 2.36%, respectively, while the Lipper Global Flexible Portfolio Funds median returned 15.07%. (Returns for all share classes since inception are also shown in the "Performance at a Glance" table on page 180, along with additional details on the Indexes. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.)

Market review

The global markets accelerated for the year ended July 31, 2007 with the MSCI World Free Index (net US) gaining 20.45%. The S&P 500 Index lagged, returning 16.13% for the year, while the Japanese TOPIX Index returned 5.51% for the same period. In the US, the equity markets lagged the indexes of many other developed nations due to concerns in the housing market, particularly in the subprime mortgage arena (subprime mortgages are riskier loans in that they are made to borrowers unable to qualify under traditional, more stringent criteria due to a limited or blemished credit history). In August 2006 and throughout the rest of the fiscal year, many US homebuilders lowered earnings expectations based on spikes in inventory levels. Throughout the reporting period, subprime delinquencies ballooned as interest rates rose and credit spreads widened. Crude oil prices dipped significantly during the period, only to end the period at si milar levels to the prior year. Additionally, the euro rose against the US dollar, while the Japanese yen fell.

Advisors' comments

Analytic Investors

We use a multi-strategy approach comprised of long-short equities, short call options and a global asset allocation overlay comprised of derivatives, with exposure to global fixed income, equity and currency markets. During the period, the equities, currencies and futures positions positively contributed to performance, while the options we wrote on sectors and indexes subtracted minimally in the up market.

Advisor's comments – continued

Long-short equities contributed 13.9% to our segment's performance over the reporting period. Equity positions with certain value characteristics, such as companies with above-average earnings-to-price (a valuation ratio of a company's current share price compared to its per-share earnings) and book-to-price (a ratio used to compare a stock's market value to its book value) ratios helped as investors continued to favor these types of characteristics. In addition, a tilt away from companies with above-average efficiency characteristics, such as inventory turnover, also helped performance. A move away from some technical factors, such as three-month returns, subtracted from performance.

Our stock selection process generally added value over the period, with industrials, healthcare and consumer discretionary among the best performing sectors. In contrast, our positions in the energy, information technology and telecommunications sectors had a negative impact on returns. Our top equity performers were long positions in Fiat SPA, Fletcher Building and Cummins, Inc., all of which outperformed in the period. A short position in Unisys Corporation,¹ and long positions in Sempra Energy and Santos Limited,¹ detracted from relative performance and were the worst-performing stock positions. (Short positions represent borrowed securities, which are sold and must be purchased and returned to the lender at a later date, in hopes of making a profit. A short position in a rising security generally results in a loss.)

Despite the global market rally, option positions subtracted modestly from performance. By comparing our forecasted volatility and market implied volatility, we were able to opportunistically identify and sell overvalued call options (a call option is a financial contract between the buyer and seller of a particular option). In particular, calls written on the PHLX Semiconductor Sector Index², the Amex Airline Index³ and the S&P 500 Index added value, despite the market rally. Calls written on the CBOE Oil Index⁴ and FTSE 100 Index⁵ hurt performance, as these indexes rallied substantially in the 12-month period.

Our global asset allocation overlay added 1.9% to our segment during the fiscal year, as currencies and equities positively contributed to performance, while fixed income marginally subtracted. We experienced currency gains from short positions in the Japanese yen and Swiss franc, and a long position in the Australian dollar. However, our exposure to the Canadian dollar and short position in the euro detracted from results. Within equities, long positions in the CAC 40 Index⁶ and TOPIX Index⁷ added to performance, while short positions in the Hang Seng Index⁸ subtracted from performance. Lastly, within fixed income futures, long positions in Japanese bonds hurt performance, while short positions in the German bond market helped performance.

Wellington Management

We employ a multi-strategy approach to managing our portfolio. That said, the biggest contributor to overall performance was an allocation to our Global Opportunities sub-portfolio, which represented our largest single allocation during the period. Supported by the broad-based strength in the global equity markets, this

Advisors' comments – concluded

sub-portfolio, which represented an average weight of just over 20% of our portion of the Portfolio, posted a strong return during the period. Due to the strength in emerging equity markets, the Emerging Markets sub-portfolio, which represented an average weight of over 5%, was also a significant contributor to overall performance. China was one of the strongest emerging markets during the fiscal year and, as a result, the China Opportunities sub-portfolio was another significant positive contributor to results. This sub-portfolio, which was initiated at the beginning of December, represented an average weight of just under 8%. Another positive contributor to performance was the Metals sub-portfolio. The continued strength in commodity pricing helped this sub-portfolio, which represented an average weight of just over 3%, post a solid return during the period.

Having an underweight to equities hurt performance, both on an absolute basis and relative to the Index, due to the global equity market rally during the last twelve months. Our portion of the Portfolio had an average net equity exposure of just under 40% during the period. The hedge overlay sub-portfolio, which consisted primarily of short positions in the Russell 2000 Index and the S&P 500 Index also significantly detracted from performance.

(Please note: After the close of the fiscal reporting period, Goldman Sachs Asset Management, L.P. was appointed to serve as an additional advisor to the Portfolio. More details regarding this appointment can be found on page 5 of this annual report.)

The Portfolio may be appropriate for investors seeking long term capital appreciation who are able to withstand short-term fluctuations in the equity markets and fixed income markets in return for potentially higher returns over the long-term. The Portfolio may employ investment strategies that involve greater risks than the strategies used by many other mutual funds, including increased use of short sales (which involve the risk of an unlimited increase in the market value of the security sold short, which could result in a theoretically unlimited loss), leverage and derivative transactions, and hedging strategies. The value of the Portfolio changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the issuers of securities in which the Portfolio invests. The value of the Portfolio's investments in foreign securities may fall due to adverse political, social and economic developments abroad and due to decreases in foreign currency values relative to the US dollar. It is important to note that an investment in the Portfolio is only one component of a balanced investment plan.

Average annual total returns for periods ended June 30, 2007, after deduction of the maximum sales charge or UBS PACE Select program fee, were as follows: Class A—1-year period, 9.55%; since inception, 6.67%; Class B—1-year period, 10.15%; since inception, 10.25%; Class C—1-year period, 14.23%; since inception, 11.31%; Class P—1-year period, 14.54%; since inception, 10.35%.

The annualized gross and net expense ratios, respectively, for each class of shares as in the November 30, 2006 prospectuses were as follows: Class A—2.58% and 2.48%; Class B—3.73% and 3.23%; Class C—3.34% and 3.23%; Class Y—2.33% and 2.23%; and Class P—2.33% and 2.23%. The Portfolio commenced operations on April 3, 2006. These gross ratios are estimates for the Portfolio's first fiscal year and are based on assets as of October 2006. Net expenses reflect fee waivers and/or expense reimbursements, if any, pursuant to an agreement that is in effect to cap the expenses. UBS Global Asset Management (Americas) Inc. ("UBS Global AM") has entered into a written fee waiver/expense reimbursement agreement pursuant to which UBS Global AM is contractually obligated to waive its management fees and/or reimburse the Portfolio so that the ordinary total operating expenses of each class through December 1, 2007 (exclu ding dividend expense, borrowing costs and interest expense, if any) would not exceed the following: Class A—1.95%; Class B—2.70%; Class C—2.70%; Class Y—1.70%; and Class P—1.70%. The Portfolio has agreed to repay UBS Global AM for any reimbursed expenses to the extent that it can do so over the following three fiscal years without causing the Portfolio's expenses in any of those three years to exceed the expense caps described above.

¹  Since inception returns are calculated as of commencement of issuance on April 10, 2006 for Class P and A shares, May 19, 2006 for Class B shares, April 11, 2006 for Class C shares. Class Y shares commenced issuance on April 3, 2006 and had been totally redeemed by July 26, 2006. Since inception returns for the Indexes and Lipper median are shown as of April 30, 2006, which is the month-end after the inception date of the oldest share class (Class P).

²  Maximum sales charge for Class A shares is 5.5%. Class A shares bear ongoing 12b-1 service fees.

³  Maximum contingent deferred sales charge for Class B shares is 5% imposed on redemptions and is reduced to 0% after a maximum of six years. Class B shares bear ongoing 12b-1 service and distribution fees.

⁴  Maximum contingent deferred sales charge for Class C shares is 1% imposed on redemptions and is reduced to 0% after one year. Class C shares bear ongoing 12b-1 service and distribution fees.

⁵  Class P shares do not bear initial or contingent deferred sales charges or ongoing 12b-1 service and distribution fees, but are subject to a maximum annual UBS PACE Select program fee of 1.5% of the value of Class P shares.

If an investor sells or exchanges shares less than 90 days after purchase, a redemption fee of 1.00% of the amount sold or exchanged will be deducted at the time of the transaction, except as noted otherwise in the prospectuses.

The Merrill Lynch US Treasury 1-5 Year Index: An unmanaged index tracking US Treasury securities with maturities between 1 and 5 years.

The MSCI World Free Index (net US) is a broad-based securities index that represents the US and developed international equity markets in terms of capitalization and performance. It is designed to provide a representative total return for all major stock exchanges located inside and outside the United States. This benchmark has been calculated net of withholding tax from a US perspective.

Consumer Price Index (CPI) produces monthly data on changes in the prices paid by urban consumers for a representative basket of goods and services. The index is calculated by the Bureau of Labor Statistics.

Past performance does not predict future performance, and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares. The return and principal value of an investment will fluctuate, so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the ex-dividend dates. Current performance may be higher or lower than the performance data quoted. For month-end performance figures, please visit http://www.ubs.com.

Lipper peer group data calculated by Lipper Inc.; used with permission. The Lipper median is the return of the fund that places in the middle of a Lipper peer group.

TIPS  Treasury inflation protected securities ("TIPS") are debt securities issued by the US Treasury whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. The interest rate paid by the TIPS is fixed, while the principal value rises or falls based on changes in a published Consumer Price Index ("CPI"). Thus, if inflation occurs, the principal and interest payments on the TIPS are adjusted accordingly to protect investors from inflationary loss. During a deflationary period, the principal and interest payments decrease, although the TIPS principal amounts will not drop below their face amounts at maturity. In exchange for the inflation protection, the TIPS generally pay lower interest rates than typical US Treasury securities. Only if inflation occurs will TIPS offer a higher real yield than a conventional Treasury bond of the same mat urity.

Understanding your Portfolio's expenses (unaudited)

As a shareholder of a Portfolio, you incur two types of costs: (1) transactional costs (as applicable), Including sales charges (loads), or ongoing program fees; and (2) ongoing Portfolio costs, including management fees; service and/or distribution (12b-1) fees (if applicable); and other Portfolio expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in each Portfolio 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, February 1, 2007 to July 31, 2007.

Actual expenses

The first line for each class of shares in the table below for each Portfolio 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 class of shares for each respective Portfolio under the heading entitled "Expenses paid during period" to estimate the expenses you paid on your account during the period.

Hypothetical example for comparison purposes

The second line for each class of shares in the table below for each Portfolio provides information about hypothetical account values and hypothetical expenses based on that Portfolio's actual expense ratios for each class of shares and an assumed rate of return of 5% per year before expenses, which is not that Portfolio's actual return for each class of shares. 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 Portfolio 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 Portfolio costs only and do not reflect any transactional costs (as applicable), such as sales charges (loads), or program fees. Therefore, the second line in the table for each class of shares for each Portfolio is useful in comparing ongoing Portfolio costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs or program fees were included, your costs would have been higher.

1  As of August 1, 2003, the Portfolio has adopted the method of accounting for interim payments on swap contracts in accordance with Financial Accounting Standards Board Statement No. 133. These interim payments are reflected within net realized and unrealized gain (loss) from investment activities, however, prior to August 1, 2003, these interim payments were reflected within interest income (or as an offset to interest income) on the Statement of operations. The effect of this change for the year ended July 31, 2004 was to decrease net investment income per share by $0.01 on all share classes and increase net realized and unrealized gain (loss) from investment activities per share by $0.01 on all share classes, and decrease the ratio of net investment income by 0.05% and 0.04% on Class A and Class B, respectively.

2  Calculated using the average month-end shares outstanding for the year.

3  Amount represents less than $0.005 per share.

4  Total investment return is calculated assuming a $10,000 investment on the first day of each year reported, reinvestment of all dividends and other distributions, if any, at net asset value on the ex-dividend dates, and a sale at net asset value on the last day of each year reported. The figures do not include any applicable sales charges or redemption fees; results would be lower if they were included. Returns do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.

1  As of August 1, 2003, the Portfolio has adopted the method of accounting for interim payments on swap contracts in accordance with Financial Accounting Standards Board Statement No. 133. These interim payments are reflected within net realized and unrealized gain (loss) from investment activities, however, prior to August 1, 2003, these interim payments were reflected within interest income (or as an offset to interest income) on the Statement of operations. The effect of this change for the year ended July 31, 2004 was to decrease net investment income per share by $0.01 on all share classes and increase net realized and unrealized gain (loss) from investment activities per share by $0.01 on all share classes, and decrease the ratio of net investment income by 0.05% on Class P.

2  Calculated using the average month-end shares outstanding for the year.

3  Total investment return is calculated assuming a $10,000 investment on the first day of each year reported, reinvestment of all dividends and other distributions, if any, at net asset value on the ex-dividend dates, and a sale at net asset value on the last day of each year reported. The figures do not include any applicable program or redemption fees; results would be lower if they were included. Returns do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.

1  As of August 1, 2003, the Portfolio has adopted the method of accounting for interim payments on swap contracts in accordance with Financial Accounting Standards Board Statement No. 133. These interim payments are reflected within net realized and unrealized gain (loss) from investment activities, however, prior to August 1, 2003, these interim payments were reflected within interest income (or as an offset to interest income) on the Statement of operations. The effect of this change for the year ended July 31, 2004 was to increase net investment income per share by $0.02 on all share classes and decrease net realized and unrealized gain (loss) from investment activities per share by $0.02 on all share classes, and increase the ratio of net investment income by 0.17% on Class P.

2  Calculated using the average month-end shares outstanding for the year.

3  Amount represents less than $0.005 per share.

4  Total investment return is calculated assuming a $10,000 investment on the first day of each year reported, reinvestment of all dividends and other distributions, if any, at net asset value on the ex-dividend dates, and a sale at net asset value on the last day of each year reported. The figures do not include any applicable program or redemption fees; results would be lower if they were included. Returns do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.

5  The investment manager recouped expenses previously reimbursed by the investment manager on behalf of the Portfolio, not to exceed the expense cap.

UBS PACE Select Advisors Trust

Notes to financial statements

Organization and significant accounting policies

UBS PACE Select Advisors Trust (the "Trust") is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended, as an open-end management investment company currently composed of fifteen separate investment portfolios and was organized as a Delaware statutory trust under the laws of the State of Delaware by Certificate of Trust dated September 9, 1994, as amended June 9, 1995 and thereafter. The trustees of the Trust have authority to issue an unlimited number of shares of beneficial interest, par value $0.001 per share.

The Trust has fifteen Portfolios available for investment, each having its own investment objectives and policies: UBS PACE Money Market Investments, UBS PACE Government Securities Fixed Income Investments, UBS PACE Intermediate Fixed Income Investments, UBS PACE Strategic Fixed Income Investments, UBS PACE Municipal Fixed Income Investments, UBS PACE Global Fixed Income Investments, UBS PACE High Yield Investments, UBS PACE Large Co Value Equity Investments, UBS PACE Large Co Growth Equity Investments, UBS PACE Small/Medium Co Value Equity Investments, UBS PACE Small/Medium Co Growth Equity Investments, UBS PACE International Equity Investments, UBS PACE International Emerging Markets Equity Investments, UBS PACE Global Real Estate Securities Investments and UBS PACE Alternative Strategies Investments (collectively, the "Portfolios").

Each of the Portfolios is classified as a diversified investment company with the exception of UBS PACE Intermediate Fixed Income Investments, UBS PACE Global Fixed Income Investments, UBS PACE Global Real Estate Securities Investments and UBS PACE Alternative Strategies Investments. With the exception of UBS PACE Money Market Investments (which currently offers Class P shares only) and UBS PACE Global Real Estate Securities Investments (which currently offers Class A, Class C, Class Y and Class P shares), each Portfolio currently offers Class A, Class B, Class C, Class Y and Class P shares. (Effective on or about October 1, 2007, Class B shares will cease being offered, with exceptions for existing shareholders for exchanges or reinvesting dividends.) Each class represents interests in the same assets of the applicable Portfolio and the classes are identical except for differences in their sales charge structures, ongoing servi ce and distribution charges and certain transfer agency and related services expenses. In addition, Class B shares and all corresponding reinvested dividend shares automatically convert to Class A shares within a certain number of years after issuance which varies depending upon the amount invested. All classes of shares have equal voting privileges except that each class has exclusive voting rights with respect to its service and/or distribution plan, if any. Class Y and Class P shares have no service or distribution plan. The Portfolios' Class P shares currently are available only to participants in the UBS PACE^SM Select Advisors Program, except that UBS PACE Money Market Investments shares are also available to participants in the UBS PACE^SM Multi Advisor Program.

The Trust accounts separately for the assets, liabilities and operations of each Portfolio. Expenses directly attributable to each Portfolio are charged to that Portfolio's operations; expenses which are applicable to all Portfolios are allocated among them on a pro rata basis.

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

The preparation of financial statements in accordance with US generally accepted accounting principles requires the Trust's management to make estimates and assumptions that affect the reported amounts and

290

Notes to financial statements

disclosures in the financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies:

Valuation of investments—Each Portfolio (except UBS PACE Money Market Investments) calculates its net asset value based on the current market value for its portfolio securities. The Portfolios normally obtain market values for their securities from independent pricing sources. Independent pricing sources may use last reported sale prices, current market quotations or valuations from computerized "matrix" systems that derive values based on comparable securities. Securities traded in the over-the-counter ("OTC") market and listed on The Nasdaq Stock Market, Inc. ("Nasdaq") normally are valued at the NASDAQ Official Closing Price. Other OTC securities are valued at the last bid price available prior to valuation. Securities which are listed on US and foreign stock exchanges normally are valued at the last sale price on the day the securities are va lued or, lacking any sales on such day, at the last available bid price. Securities listed on foreign stock exchanges (and certain related derivatives) may be fair valued based on significant events that have occurred subsequent to the close of the foreign markets. UBS PACE International Equity Investments, UBS PACE International Emerging Markets Equity Investments, UBS PACE Global Real Estate Securities Investments and UBS PACE Alternative Strategies Investments may use a systematic fair valuation model provided by an independent third party to value securities principally traded in foreign markets (and certain related derivatives) in order to adjust for possible stale pricing that may occur between the close of the foreign exchanges and the time for valuation. If a security is valued at a "fair value", that value is likely to be different from the last quoted market price for the security. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated a s the primary market by UBS Global Asset Management (Americas) Inc. If a market value is not available from an independent pricing source for a particular security, that security is valued at fair value as determined in good faith by or under the direction of the Trust's Board of Trustees (the "Board"). Various factors may be reviewed in order to make a good faith determination of a security's fair value. These factors include, but are not limited to, the type and cost of the security; contractual or legal restrictions on resale of the security; relevant financial or business developments of the issuer; actively traded similar or related securities; conversion or exchange rights on the security; related corporate actions; and changes in overall market conditions. If events occur that materially affect the value of securities (particularly non-US securities) between the close of trading in those securities and the close of regular trading on the New York Stock Exchange ("NYSE"), the securities are fair valued . The amortized cost method of valuation, which approximates market value, generally is used to value short-term debt instruments with sixty days or less remaining to maturity, unless the Board determines that this does not represent fair value. Investments of the UBS PACE Money Market Investments Portfolio are valued using the amortized cost method of valuation. All investments quoted in foreign currencies will be valued daily in US dollars on the basis of the foreign currency exchange rates prevailing at the time such valuation is determined by the Portfolios' custodian.

In September 2006, the Financial Accounting Standards Board ("FASB") issued Statement on 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 July 31, 2007, 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 c ertain measurements reported on the Statement of operations for a fiscal period.

Repurchase agreements—The Portfolios 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

291

Notes to financial statements

(or upon demand) and price. The Portfolios maintain 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 Portfolios 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 Portfolios 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 in solvent, the Portfolios 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 Portfolio (with the exception of UBS PACE Municipal Fixed Income Investments) 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").

Investment transactions, investment income and expenses—Investment transactions are recorded on the trade date. Realized gains and losses from investment transactions and foreign exchange transactions are calculated using the identified cost method. Dividend income is recorded net of withholding taxes on the ex-dividend date ("ex-date") (except in the case of certain dividends from foreign securities which are recorded as soon after the ex-date as the respective Portfolio, using reasonable diligence, becomes aware of such dividends). 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.

Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of outstanding shares (or the value of dividend-eligible shares, as appropriate) of each class at the beginning of the day (after adjusting for current capital share activity of the respective classes). Class-specific expenses are charged directly to the applicable class of shares.

Foreign currency translation—The books and records of the Portfolios are maintained in US dollars. Foreign currency amounts are translated into US dollars as follows: (1) the foreign currency market value of investment securities and other assets and liabilities stated in foreign currencies are translated using foreign currency exchange rates determined as of the close of regular trading on the NYSE; and (2) purchases, sales, income and expenses are translated at the rate of exchange prevailing on the respective dates of such transactions. The resulting exchange gains and losses are included on the Statement of operations.

The Portfolios do not generally isolate the effects of fluctuations in foreign exchange rates from the effects of fluctuations in the market prices of securities. However, the Portfolios do isolate the effect of fluctuations in foreign exchange rates when determining the realized gain or loss upon the sale or maturity of foreign currency-denominated debt obligations pursuant to US federal income tax regulations; such amount is categorized as realized foreign currency transaction gain or loss for both financial reporting and income tax purposes. Net realized foreign currency transaction gain (loss) is treated as ordinary income (loss) for income tax reporting purposes.

Forward foreign currency contracts—Certain Portfolios may enter into forward foreign currency contracts ("forward contracts") in connection with planned purchases or sales of securities or to hedge the US dollar value of portfolio securities denominated in a particular currency. The Portfolios may also engage in cross-hedging by using forward contracts in one currency to hedge fluctuations in the value of securities denominated in a different currency if the applicable investment sub-advisor anticipates that there is a

292

Notes to financial statements

correlation between the two currencies. Forward contracts may also be used to shift a Portfolio's exposure to foreign currency fluctuations from one country to another. UBS PACE Alternative Strategies Investments may also enter into foreign currency strategies for purposes of risk management, efficient asset allocation and in pursuit of its investment objective.

The Portfolios have no specific limitation on the percentage of assets which may be committed to such contracts; however, the value of all forward contracts will not exceed the value of a Portfolio's total assets. The Portfolios may enter into forward contracts or maintain a net exposure to forward contracts only if (1) the consummation of the contracts would not obligate the Portfolios to deliver an amount of foreign currency in excess of the value of the positions being hedged by such contracts or (2) the Portfolios maintain cash or liquid securities in a segregated account in an amount determined pursuant to the Portfolios' segregation policies as disclosed in the Trust's Statement of Additional Information.

Risks may arise upon entering into forward contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of foreign currencies relative to the US dollar or each other.

Fluctuations in the value of open forward contracts are recorded for book purposes as unrealized gains or losses on forward foreign currency contracts by the Portfolios. Realized gains and losses on forward foreign currency contracts include net gains or losses recognized by the Portfolios on contracts which have matured.

Securities traded on to-be-announced basis—The Portfolios may from time to time purchase securities on a to-be-announced ("TBA") basis. In a TBA transaction, the Portfolio commits to purchasing or selling securities for which all specific information is not yet known at the time of the trade, particularly the face amount and maturity date of the underlying security transactions. Securities purchased on a TBA basis are not settled until they are delivered to the Portfolio, normally 15 to 45 days later. Beginning on the date the Portfolio enters into a TBA transaction, cash, US government securities or other liquid securities are segregated in an amount equal in value to the purchase price of the TBA security. These transactions are subject to market fluctuations, and their current value is determined in the same manner as for other securities.

At July 31, 2007 UBS PACE Government Securities Fixed Income Investments, UBS PACE Intermediate Fixed Income Investments and UBS PACE Strategic Fixed Income Investments held TBA securities with a total cost of $182,173,898, $35,919,868 and $40,318,359, respectively.

Option writing—Certain Portfolios may write (sell) put and call options on securities or derivative instruments in order to gain exposure to or protect against changes in the markets. When a Portfolio writes a call or a put option, an amount equal to the premium received by the Portfolio is included on the Portfolio's Statement of assets and liabilities as an asset and as an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. If an option which the Portfolio has written either expires on its stipulated expiration date or the Portfolio enters into a closing purchase transaction, the Portfolio realizes a gain (or loss if the cost of a closing purchase transaction exceeds the premium received when the option was written) without regard to any unrealized gain or loss on the underlying security or derivative instrument, and the liability related to such option is extinguished. If a call option which the Portfolio has written is exercised, the Portfolio recognizes a realized capital gain or loss (long-term or short-term, depending on the holding period of the underlying security) from the sale of the underlying security or derivative instrument and the proceeds from the sale are increased by the premium originally received. If a put option which the Portfolio has written is exercised, the amount of the premium originally received reduces the cost of the security or derivative instrument which the Portfolio purchases upon exercise of the option.

293

UBS PACE Select Advisors Trust

Notes to financial statements

In writing an option, the Portfolios bear the market risk of an unfavorable change in the price of the derivative instrument, security or currency underlying the written option. Exercise of an option written by a Portfolio could result in the Portfolio selling or buying a derivative instrument, security or currency at a price different from current market value.

Written option activity for the year ended July 31, 2007 for UBS PACE Government Securities Fixed Income Investments, UBS PACE Strategic Fixed Income Investments and UBS PACE Alternative Strategies Investments was as follows:

Written call options—In the event that the counterparty (usually a securities dealer or a bank) to the written options contracts defaults on its obligation under the contracts, the maximum loss related to these contracts is limited to the market value of the securities subject to the written call options outstanding, which aggregated $623,604 and $122,813 for UBS PACE Strategic Fixed Income Investments and UBS PACE Alternative Strategies Investments, respectively at July 31, 2007.

Written put options—In the event that the counterparty (usually a securities dealer or a bank) to the written options contracts defaults on its obligation under the contracts, the maximum loss related to these contracts is limited to the notional amount of the written put options outstanding. At July 31, 2007, none of the Portfolios held written put options.

Purchased options—Certain Portfolios may also purchase put and call options. Purchasing call options tends to increase exposure to the underlying instrument. Purchasing put options tends to decrease exposure to the underlying instrument. The Portfolio pays a premium which is included on the Statement of assets and liabilities as an investment and subsequently marked to market to reflect the current value of the option. Premiums paid for purchasing options which expire are treated as realized losses. The risk associated with purchasing put and call options is limited to the premium paid or the loss of the benefit of the transaction should the counterparty default. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying future, security or currency transaction to determine the realized gain or loss.

Futures contracts—Certain Portfolios may use financial futures contracts for hedging purposes and to adjust exposure to US and foreign markets in connection with a reallocation of the Portfolios' assets or to manage the average duration of a Portfolio. In addition, a Portfolio may purchase or sell futures contracts or

294

UBS PACE Select Advisors Trust

Notes to financial statements

purchase options thereon to increase or reduce its exposure to an asset class without purchasing or selling the underlying securities, either as a hedge or to enhance return or realize gains. Using financial futures contracts involves various market risks. However, imperfect correlations between futures contracts and the related securities or markets, or market disruptions, do not normally permit full control of these risks at all times. The maximum amount at risk from the purchase of a futures contract is the contract value or the loss of the benefit of the transaction should the counterparty default.

Upon entering into a financial futures contract, a Portfolio is required to deliver to a broker an amount of cash and/or government securities equal to a certain percentage of the contract amount. This amount is known as the "initial margin". Subsequent payments, known as "variation margin", generally are made or received by the Portfolio each day depending on the fluctuations in the value of the underlying financial futures contracts, except that in the case of certain futures contracts payments may be made or received at settlement. Such variation margin is recorded for financial statement purposes on a daily basis as an unrealized gain or loss on futures until the financial futures contract is closed, at which time the net gain or loss is reclassified to realized gain or loss on futures.

Short sales "Against the Box"—Each Portfolio (other than UBS PACE Money Market Investments and UBS PACE Municipal Fixed Income Investments) may engage in short sales of securities it owns or has the right to acquire at no added cost through conversion or exchange of other securities it owns (short sales "against the box"). To make delivery to the purchaser in a short sale, the executing broker borrows the securities being sold short on behalf of a Portfolio, and that Portfolio is obligated to replace the securities borrowed at a date in the future. When a Portfolio sells short, it establishes a margin account with the broker effecting the short sale and deposits collateral with the broker. In addition, the Portfolio maintains, in a segregated account with its custodian, the securities that could be used to cover the short sale. Each Portfolio inc urs transaction costs, including dividend and interest expense, in connection with opening, maintaining and closing short sales "against the box".

A Portfolio might make a short sale "against the box" to hedge against market risks when its investment manager or sub-advisor believes that the price of a security may decline, thereby causing a decline in the value of a security owned by the Portfolio or a security convertible into or exchangeable for a security owned by the Portfolio. In such case, any loss in the Portfolio's long position after the short sale should be reduced by a corresponding gain in the short position. Conversely, any gain in the long position after the short sale should be reduced by a corresponding loss in the short position. The extent to which gains or losses in the long position are reduced will depend upon the amount of the securities sold short relative to the amount of the securities a Portfolio owns, either directly or indirectly, and in the case where the Portfolio owns convertible securities, changes in the investment values or conversion prem iums of such securities.

Short sales—UBS PACE Alternative Strategies Investments and UBS PACE Global Real Estate Securities Investments can enter into short sales whereby they sell a security they generally do not own, in anticipation of a decline in the security's price. The initial amount of a short sale is recorded as a liability which is marked to market daily. Fluctuations in the value of this liability are recorded as unrealized gains or losses on the Statement of operations. If the Portfolio shorts a security when also holding a long position in the security (a "short against the box"), as the security price declines, the short position increases in value, offsetting the long position's decrease in value. The opposite effect occurs if the security price rises. The Portfolio will realize a gain or loss upon closing of the short sale (returning the security to the c ounterparty by way of purchase or delivery of a long position owned). The Portfolio is liable to the buyer for any dividends and interest payable on securities while those securities are in a short position. These dividends and interest are booked as an expense of the Portfolio. UBS PACE Alternative Strategies Investments maintains one or more

295

Notes to financial statements

accounts containing cash and/or liquid assets at such a level that the amount deposited in the account plus that amount deposited with the broker as collateral will, at minimum, equal the current value of the stock sold short. UBS PACE Global Real Estate Securities Investments did not engage in short sales during the period ended July 31, 2007.

Reverse repurchase agreements—Certain Portfolios may enter into reverse repurchase agreements with qualified third party broker-dealers. Interest on the value of reverse repurchase agreements issued and outstanding is based upon competitive market rates at the time of issuance. At the time the Portfolio enters into reverse repurchase agreements, the Portfolio establishes and maintains a segregated account with the Portfolio's custodian containing liquid securities having a value not less than the repurchase price, including accrued interest, of the reverse repurchase agreement. The Portfolios did not enter into any reverse repurchase agreements during the period ended July 31, 2007.

Interest rate swap agreements—Certain Portfolios may enter into interest rate swap agreements to protect themselves from interest rate fluctuations. UBS PACE Alternative Strategies Investments may also enter into swap transactions for purposes of risk management, efficient asset allocation and in pursuit of its investment objective. This type of swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to a specified interest rate(s) for a specified amount. The payment flows are usually netted against each other, with the difference being paid by one party to the other.

Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the contract. The loss incurred by the failure of a counterparty is generally limited to the net interest payment to be received by the Portfolio. Therefore, the Portfolio considers the creditworthiness of the counterparty to a swap contract in evaluating potential credit risk.

The Portfolio accrues for interim payments on swap contracts on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swap contracts on the Statement of assets and liabilities. Once interim payments are settled in cash, the net amount is recorded as realized gain/loss on swaps, in addition to realized gain/loss recorded upon the termination of swap contracts on the Statement of operations. Fluctuations in the value of swap contracts are recorded for financial statement purposes as unrealized appreciation or depreciation of swaps.

At July 31, 2007, UBS PACE Government Securities Fixed Income Investments and UBS PACE Strategic Fixed Income Investments had outstanding interest rate swap contracts with the following terms:

Credit default swap agreements—Credit default swap agreements involve commitments to make or receive payments in the event of a default of a security or a credit event. As a buyer, the Portfolio would make periodic payments to the counterparty, and the Portfolio would receive payments only upon the occurrence of a credit event. If no credit event occurs, the Portfolio will lose its periodic stream of payments over the term of the contract. However, if a credit event does occur, the Portfolio typically would receive full notional value for a reference obligation that may have little or no value. As a seller, the Portfolio would receive periodic payments from the counterparty, and the Portfolio would make payments only upon the occurrence of a credit event. If no default or credit event occurs, the Portfolio will gain the periodic stream of payment s it received over the term of the contract and the counterparty will lose its periodic stream of payments over the term of the contract. However, if a default or credit event occurs, the Portfolio typically pays full notional value for a reference obligation that may have little or no value. Credit default swaps may involve greater risks than if the Portfolio had invested in the reference obligation directly and are subject to general market risk, liquidity risk and credit risk.

At July 31, 2007, UBS PACE Strategic Fixed Income Investments had outstanding credit default swap contracts with the following terms:

Notes to financial statements

Dividends and distributions—Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions are 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

Investing in securities of foreign issuers and currency transactions may involve certain considerations and risks not typically associated with investments in the United States. These risks include revaluation of currencies, adverse fluctuations in foreign currency values and possible adverse political, social and economic developments, including those particular to a specific industry, country or region, which could cause the securities and their markets to be less liquid and prices more volatile than those of comparable US companies and US government securities. These risks are greater with respect to securities of issuers located in emerging market countries in which the UBS PACE Global Fixed Income Investments, UBS PACE International Equity Investments, UBS PACE International Emerging Markets Equity Investments, UBS PACE Global Real Estate Securities Investments and UBS PACE Alternative Strategies Investments Portfolios are authorized to invest.

Small capitalization ("small cap") companies may be more vulnerable than larger capitalization companies to adverse business or economic developments. Small cap companies may also have limited product lines, markets or financial resources, and may be dependent on a relatively small management group. Securities of such companies may be less liquid and more volatile than securities of larger capitalization companies or the market averages in general and therefore may involve greater risk than investing in larger capitalization companies. In addition, small cap companies may not be well-known to the investing public, may not have institutional ownership and may have only cyclical, static or moderate growth prospects. These risks are greater with respect to the securities in which the UBS PACE Small/Medium Co Value Equity Investments and UBS PACE Small/Medium Co Growth Equity Investments Portfolios tend to invest.

The ability of the issuers of debt securities held by the Portfolios to meet their obligations may be affected by economic and political developments particular to a specific industry, country, state or region.

Notes to financial statements

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 investment manager, it is believed that under normal circumstances it represents a small portion of the total value of the transactions.

Notes to financial statements

On July 13, 2006, FASB released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing a Portfolio's tax return to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet a more-likely-than-not threshold would be recorded as a tax expense in the current year. Based on the Securities and Exchange Commission's announcement on December 22, 2006, the implementation of FIN 48 must be incorporated into accounting practice no later than the last business day that occurs in the period covered by the Portfolio's January 31, 2008 semiannual report. Management continues to evaluate the application of FIN 48 to the Portfolios, and is not in a position at this time to estimate the significance of its impact, if any, to the Portfolios' financial statements.

Capital Contribution from investment manager/sub-advisor

On October 31, 2006, UBS PACE Alternative Strategies Investments recorded a capital contribution from UBS Global AM, in the amount of $16,960. This amount was paid by UBS Global AM in connection with the inclusion of dividend and interest expense as operating expenses for the purpose of computing expense reimbursement. Effective December 1, 2006, dividend and interest expense was excluded from operating expenses for purposes of computing required expense waiver/reimbursement. On February 8, 2007, UBS PACE Alternative Strategies Investments recorded a capital contribution from Wellington Management Company, LLP, in the amount of $288. This amount was paid by the sub-advisor in connection with losses incurred due to the disposition of a restricted security.

Shares of beneficial interest

There is an unlimited amount of $0.001 par value shares of beneficial interest authorized. Transactions in shares of beneficial interest for each of the Portfolios, except UBS PACE Money Market Investments, about which similar information is provided on the Statement of changes in net assets, were as follows:

Subsequent events

After the close of the reporting period, Pacific Investment Management Company LLC ("PIMCO") entered into a superceding Sub-Advisory Agreement with UBS Global AM with respect to UBS PACE Government Securities Fixed Income Investments effective as of August 1, 2007. The agreement is substantially similar in all respects to the agreement which had previously been in effect but reflects a lower fee rate, as follows: UBS Global AM (not the Portfolio) pays PIMCO a fee, computed daily and payable monthly, in the annual amount of 0.20% of the average daily net assets of the Portfolio or Segment allocated to its management. UBS Global AM entered into a separate written management fee waiver agreement in order to pass through to investors the benefit of the fee reduction.

In addition, subsequent to the close of the reporting period, the investment advisory arrangements for UBS PACE Global Fixed Income Investments changed as follows: Fischer Francis Trees & Watts, Inc., (and its affiliates), terminated as a Sub-Advisor to the Portfolio, effective August 23, 2007. As a result, Rogge Global Partners, plc ("Rogge") is now the sole manager of the Portfolio. Rogge entered into a superceding Sub-Advisory Agreement with UBS Global AM on behalf of UBS PACE Global Fixed Income Investments effective August 23, 2007. The agreement is substantially similar in all respects to the agreement which had previously been in effect but reflects a lower fee rate, as follows: UBS Global AM (not the Portfolio) pays Rogge a fee, computed daily and payable monthly, at an annual rate of 0.25% on assets up to $150 million; at an annual rate of 0.18% on the next $350 million of assets; and an annual rate of 0.15% on asse ts over $500 million of the average daily net assets of the Portfolio or Segment allocated to its management. UBS Global AM entered into a separate written management fee waiver agreement in order to pass through to investors the benefit of the fee reduction. UBS Global AM began such waiver on August 1, 2007, in anticipation of the new Rogge contract's effectiveness later that month.

Furthermore, subsequent to the close of the reporting period, Goldman Sachs Asset Management, L.P. ("Goldman") was added as a sub-advisor to manage a segment of UBS PACE Alternative Strategies Investments, effective September 11, 2007. Pursuant to the Sub-Advisory Agreement with Goldman, UBS Global AM (not the Portfolio) pays Goldman a fee, computed daily and payable monthly at an annual rate of 0.80% on the first $300 million; 0.75% on the next $200 million; and 0.70% on assets in excess of $500 million of the average daily net assets of the Portfolio or Segment allocated to its management.

Effective August 1, 2007, the below Portfolio's have each entered into a revised written fee waiver/expense reimbursement agreement with UBS Global AM to maintain the total annual ordinary operating expenses (with certain exclusions such as dividend expense, borrowing cost and interest expense) at a level not to exceed the following through November 30, 2008:

These financial statements and financial highlights are the responsibility of the Trust'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 Trust'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 Trust'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 s ignificant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2007, 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 each of the respective portfolios constituting UBS PACE Select Advisors Trust at July 31, 2007, and the results of their operations, the changes in their net assets, and the financial highlights for each of the indicated periods, in conformity with US generally accepted accounting principles.

UBS PACE Small/Medium Co Growth Equity Investments—Board Approval of Sub-Advisory Agreement (unaudited)

February 2007 board meeting:

Background—At a meeting of the UBS PACE Select Advisors Trust's (the "Trust") board on February 7, 2007, the members of the board, including the Trustees who are not "interested persons" of the Trust ("Independent Trustees"), as defined in the Investment Company Act of 1940, as amended (the "1940 Act"), considered and approved the proposed sub-advisory agreement ("Sub-Advisory Agreement") between UBS Global Asset Management (Americas) Inc. ("UBS Global AM") and Copper Rock Capital Partners, LLC ("Copper Rock") with respect to UBS PACE Small/Medium Co Growth Equity Investments (the "Portfolio"). At the recommendation of UBS Global AM, the board was being asked to replace Delaware Management Company, which had sub-advised a segment of the Portfolio, with Copper Rock. In considering the approval of the Sub-Advisory Agreement, the board was able to d raw on its knowledge of the Trust, its portfolios and UBS Global AM. The board took note of its knowledge of UBS Global AM and the advisory and sub-advisory agreements for the other portfolios of the Trust, including the extensive materials it had reviewed at its last annual contract renewal meeting for the portfolios in July 2006, and noted that it had at that time received a memorandum from its independent legal counsel discussing, among other things, the duties of board members in considering approval of advisory and sub-advisory agreements. At the meeting, the board was provided with information about Copper Rock, including information about the qualifications, backgrounds and responsibilities of Copper Rock's portfolio management team, assets under management and investment philosophy and process. The board was also provided by UBS Global AM with memoranda with additional information about Copper Rock and UBS Global AM's discussion of its reasons for recommending Copper Rock to the board, including that Copper Rock would benefit from the resources available from Old Mutual Asset Management, the majority shareholder of Copper Rock. The Board also met with members of the portfolio management team for Copper Rock, who discussed with the Board their investment philosophy.

In its consideration of the approval of the Sub-Advisory Agreement, the board considered the following factors:

Nature, extent and quality of the services under the Sub-Advisory Agreement—The board took note that at its July 2006 annual contract renewal meeting for the Trust, in connection with its review of the Trust's advisory, sub-advisory and distribution agreements, it had received and considered extensive information regarding UBS Global AM and a description of UBS Global AM's role in coordinating providers of other services to the portfolios, including oversight of the provision of sub-advisory services by the sub-advisors to the portfolios. The board's evaluation of the services to be provided by Copper Rock to the Portfolio took into account the board's knowledge and familiarity gained as members of the board of funds in the UBS New York fund complex, including the Trust and its portfolios. As noted above, the board also received extensive materia ls from UBS Global AM and from Copper Rock about Copper Rock, including a memorandum from UBS Global AM discussing its reasons for recommending Copper Rock.

The board concluded that, overall, it was satisfied with the nature, extent and quality of services expected to be provided to the Portfolio under the Sub-Advisory Agreement.

Sub-advisory fee—The board reviewed and considered the proposed contractual sub-advisory fee to be payable by UBS Global AM in light of the nature, extent and quality of the sub-advisory services anticipated to be provided by Copper Rock. The board noted that the sub-advisory fee to be paid to Copper Rock would be higher than the sub-advisory fee paid to the predecessor sub-advisor, but that UBS Global AM believed that the proposed sub-advisory fee was reasonable for sub-advisors managing the small/medium capitalization equity asset class. The board also considered that the compensation to be paid to Copper

336

UBS PACE Select Advisors Trust

UBS PACE Small/Medium Co Growth Equity Investments—Board Approval of Sub-Advisory Agreement (unaudited)

Rock would be paid by UBS Global AM, not the Portfolio and, accordingly, that the retention of Copper Rock would not increase the fees otherwise incurred by the Portfolio's shareholders.

Taking all of the above into consideration, the board determined that the proposed sub-advisory fee was reasonable in light of the nature, extent and quality of the services proposed to be provided to the Portfolio under the Sub-Advisory Agreement.

Portfolio performance—The board received and considered information with respect to Copper Rock's investment performance with separately managed accounts managed in the small to mid-cap growth equity style and the performance of the lead portfolio manager while managing a fund with an investment objective, policies and strategies substantially similar to the Portfolio. The board noted that, as Copper Rock would be a new sub-advisor to the Portfolio, the current performance of the Portfolio was not relevant to the consideration of the approval of the Sub-Advisory Agreement.

Advisor profitability—Profitability of UBS Global AM or its affiliates in providing services to the Portfolio was not a factor considered by the board, as the sub-advisory fee would be paid by UBS Global AM out of the management fee paid to it by the Portfolio, and not by the Portfolio.

Economies of scale—The board noted that, as the sub-advisory fee for the Portfolio would be paid by UBS Global AM, not by the Portfolio, consideration of economies of scale with respect specifically to the sub-advisory fee was not relevant.

Other benefits to the sub-advisor—The board was informed by management that Copper Rock's relationship with the Portfolio would be limited to its provision of sub-advisory services to the Portfolio and that therefore management believed that Copper Rock did not receive tangible ancillary benefits as a result of its relationship with the Portfolio, with the exception of possible benefits from soft dollars for the Portfolio (which would also potentially benefit the Portfolio).

In light of all of the foregoing, the board approved the Sub-Advisory Agreement for the Portfolio.

No single factor reviewed by the board was identified by the board as the principal factor in determining whether to approve the Sub-Advisory Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process. The board discussed the proposed approval of the Sub-Advisory Agreement in a private session with their independent legal counsel at which no representatives of UBS Global AM or Copper Rock were present.

UBS PACE Select Advisors Trust

UBS PACE Large Co Growth Equity Investments and UBS PACE Small/Medium Co Value Equity Investments—Board Approval of Sub-Advisory Agreements (unaudited)

May 2007 board meeting:

Background—At a meeting of the UBS PACE Select Advisors Trust's (the "Trust") board on May 9, 2007, the members of the board, including the Trustees who are not "interested persons" of the Trust ("Independent Trustees"), as defined in the Investment Company Act of 1940, as amended (the "1940 Act"), considered and approved the proposed sub-advisory agreement ("Sub-Advisory Agreement") between UBS Global Asset Management (Americas) Inc. ("UBS Global AM") and Wellington Management Company, LLP ("Wellington Management") with respect to UBS PACE Large Co Growth Equity Investments (the "Portfolio"). At the recommendation of UBS Global AM, the board was being asked to replace GE Asset Management Incorporated, which had sub-advised a segment of the Portfolio, with Wellington Management. In considering the approval of the Sub-Advisory Agreement, the board was able to draw on its knowledge of the Trust, its portfolios and UBS Global AM. The board took note of its knowledge of UBS Global AM and the advisory and sub-advisory agreements for the other portfolios of the Trust, including the extensive materials it had reviewed at its last annual contract renewal meeting for the portfolios in July 2006, and noted that it had at that time received a memorandum from its independent legal counsel discussing, among other things, the duties of board members in considering approval of advisory and sub-advisory agreements. The board was also familiar with Wellington Management generally as Wellington Management is a sub-advisor for another of the Trust's portfolios, UBS PACE Alternative Strategies Investments. The board received a memorandum from UBS Global AM discussing UBS Global AM's reasons for recommending Wellington Management as a sub-advisor for the Portfolio. The board also received materials from Wellington Management detailing Wellington Management's investment process and growth style. The board also met with members of the portfolio management team for Wellington Management, who discussed with the board their investment philosophy, investment process and the backgrounds and qualifications of the portfolio management team members.

In its consideration of the approval of the Sub-Advisory Agreement, the board considered the following factors:

Nature, extent and quality of the services under the Sub-Advisory Agreement—The board's evaluation of the services to be provided by Wellington Management to the Portfolio took into account the board's knowledge and familiarity gained as board members of funds in the UBS New York fund complex, including the Trust and its portfolios. The board received extensive materials from UBS Global AM and from Wellington Management. The board reviewed UBS Global AM's memorandum detailing its reasons for recommending Wellington Management to replace one of the three sub-advisors for the Portfolio, including Wellington Management's seasoned portfolio management team, the extensive resources available to the portfolio team within Wellington Management and UBS Global AM's belief that Wellington Management's particular growth strategy would complement well the st rategies of the Portfolio's other two sub-advisors who would continue to sub-advise the Portfolio. The board concluded that, overall, it was satisfied with the nature, extent and quality of services expected to be provided to the Portfolio under the Sub-Advisory Agreement.

Sub-advisory fee—The board reviewed and considered the proposed contractual sub-advisory fee to be payable by UBS Global AM in light of the nature, extent and quality of the sub-advisory services anticipated to be provided by Wellington Management. The board noted that the proposed sub-advisory fee that UBS Global AM had negotiated with Wellington Management would be the same as the sub-advisory fee paid to the predecessor sub-advisor. The board also considered that the compensation to be paid to Wellington Management would be paid by UBS Global AM, not the Portfolio and, accordingly, that in any event the

338

UBS PACE Select Advisors Trust

UBS PACE Large Co Growth Equity Investments and UBS PACE Small/Medium Co Value Equity Investments—Board Approval of Sub-Advisory Agreements (unaudited)

retention of Wellington Management would not change the fees otherwise incurred by the Portfolio's shareholders.

Taking all of the above into consideration, the board determined that the proposed sub-advisory fee was reasonable in light of the nature, extent and quality of the services proposed to be provided to the Portfolio under the Sub-Advisory Agreement.

Portfolio performance—The board received and considered information provided by Wellington Management with respect to Wellington Management's composite investment performance in comparison to the Russell 1000 Growth Index. The board noted that based on the composite materials provided by Wellington Management, Wellington Management had outperformed the benchmark during most stated periods although in 2006 Wellington Management had underperformed the benchmark. The portfolio management team discussed the reasons for the underperformance. The board also noted that, as Wellington Management would be a new sub-advisor to the Portfolio, the current performance of the Portfolio was not relevant to the consideration of the approval of the Sub-Advisory Agreement.

Advisor profitability—Profitability of UBS Global AM or its affiliates in providing services to the Portfolio was not a factor considered by the board, as the sub-advisory fee would be paid by UBS Global AM out of the management fee paid to it by the Portfolio, and not by the Portfolio.

Economies of scale—The board noted that, as the sub-advisory fee for the Portfolio would be paid by UBS Global AM, not by the Portfolio, consideration of economies of scale with respect specifically to the sub-advisory fee were not relevant.

Other benefits to the sub-advisor—The board was informed by management that Wellington Management's relationship with the Portfolio would be limited to its provision of sub-advisory services to the Portfolio and that therefore management believed that Wellington Management did not receive tangible ancillary benefits as a result of its relationship with the Portfolio, with the exception of possible benefits from soft dollars for the Portfolio (which would also potentially benefit the Portfolio).

In light of all of the foregoing, the board approved the Sub-Advisory Agreement for the Portfolio.

Background—The members of the board also considered and approved the proposed amended sub-advisory agreement (the "Amended Sub-Advisory Agreement") between UBS Global AM and Opus Capital Management ("Opus") with respect to UBS PACE Small/Medium Co Value Equity Investments (the "Portfolio"). UBS Global AM requested that the board approve the Amended Sub-Advisory Agreement because it provided for a reduction in the sub-advisory fee paid to Opus by UBS Global AM and superseded a fee waiver agreement, previously approved by the board, in place between UBS Global AM and Opus with respect to the fee paid to Opus by UBS Global AM. In its consideration of the approval of the proposed Amended Sub-Advisory Agreement, the board considered the following factors:

Nature, extent and quality of the services under the Amended Sub-Advisory Agreement—The board was familiar with the services provided by Opus to the Portfolio as Opus is currently one of the sub-advisers for the Portfolio. The board considered that Opus had represented to UBS Global AM that the fee reduction embodied in the Amended Sub-Advisory Agreement would not result in a lower level of services to the Portfolio or to UBS Global AM. The board concluded that, overall, it was satisfied with the nature, extent and quality of services to be provided to the Portfolio under the proposed Amended Sub-Advisory Agreement.

339

UBS PACE Select Advisors Trust

Sub-advisory fee—The board reviewed and considered the proposed contractual sub-advisory fee to be payable by UBS Global AM to Opus in light of the nature, extent and quality of the sub-advisory services currently provided and anticipated to be provided by Opus. The board noted that the proposed sub-advisory fee that UBS Global AM had negotiated with Opus would be lower than the current contractual fee rate, but at the same level as paid after giving effect to the existing fee waiver arrangement. The board also considered that the compensation to be paid to Opus would be paid by UBS Global AM, not the Portfolio and, accordingly, that the contractual fee reduction would not reduce the fees otherwise incurred by the Portfolio's shareholders but would instead benefit UBS Global AM. UBS Global AM noted that it had negotiated the lower fee with Opus i n light of information regarding fees Opus was earning from another mutual fund, and that the reduction would bring the fee paid Opus more in line with the level of fees UBS Global AM paid to the Portfolio's other two sub-advisors. UBS Global AM also reviewed with the board the level of fees that had been paid to a prior sub-advisor that had been replaced by Opus. Taking all of the above into consideration, the board determined that the proposed sub-advisory fee was reasonable in light of the nature, extent and quality of the services proposed to be provided to the Portfolio under the Amended Sub-Advisory Agreement.

Portfolio performance—The board noted that it had received at this meeting and at previous meetings information with respect to Opus's performance as a sub-adviser to the Portfolio and reviewed Opus's performance at each meeting and would conduct an extensive review of the performance of the Portfolio and the other portfolios of the Trust at its July meeting. The board determined that the Portfolio's performance was not relevant specifically to its consideration of the Amended Sub-Advisory Agreement; Opus was currently a sub-adviser to the Portfolio, and the amendment reflected only a reduction in the sub-advisory fee payable to Opus by UBS Global AM to bring it more in line with the fees paid the Portfolio's other sub-advisors. The services provided to the Portfolio would not change as a result of this approval.

Advisor profitability—The board recognized that as a result of the fee rate change, UBS Global AM could retain more of the management fee paid to it by the Portfolio; however, UBS Global AM did not believe that the amount involved would materially change its overall profitability with respect to the Portfolio. The board also recognized that it would be receiving extensive updated information regarding UBS Global AM's profitability within the following two months in preparation for its annual reconsideration of the management agreement with UBS Global AM.

Economies of scale—The board noted that, as the sub-advisory fee for the Portfolio would be paid by UBS Global AM, not by the Portfolio, consideration of economies of scale with respect specifically to the sub-advisory fee were not relevant.

Other benefits to the sub-advisor—The board was informed by management that Opus's relationship with the Portfolio would be, as it currently was, limited to its provision of sub-advisory services to the Portfolio and that therefore management believed that Opus did not receive tangible ancillary benefits as a result of its relationship with the Portfolio, with the exception of possible benefits from soft dollars for the Portfolio (which would also potentially benefit the Portfolio).

In light of all of the foregoing, the board approved the Amended Sub-Advisory Agreement for the Portfolio.

No single factor reviewed by the board was identified by the board as the principal factor in determining whether to approve the Sub-Advisory Agreement or the Amended Sub-Advisory Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process. The board discussed the proposed approval of the Sub-Advisory Agreement and the Amended Sub-Advisory Agreement in a private session with their independent legal counsel at which no representatives of UBS Global AM, Wellington Management or Opus were present.

July board meeting:

Background—At a meeting of the UBS PACE Select Advisors Trust's (the "Trust") board on July 18, 2007, the members of the board, including the Trustees who are not "interested persons" of the Trust ("Independent Trustees"), as defined in the Investment Company Act of 1940, as amended (the "1940 Act"), considered and approved the continuance of the Investment Management and Administration Agreement between UBS Global Asset Management (Americas) Inc. ("UBS Global AM") and the Trust, on behalf of each series of the Trust (each a "Portfolio" and together the "Portfolios") and, for those Portfolios with Subadvisers, the subadvisory agreements for the Portfolios. (Throughout this discussion, each subadviser to a Portfolio is referred to as a "Subadviser" and each subadvisory agreement is referred to as a "Subadvisory Agreement.") In preparing for the me eting, the board members had requested and received extensive information from UBS Global AM to assist them, including, with respect to each Portfolio, performance and expense information for other investment companies with similar investment objectives. The board received and considered a variety of information about UBS Global AM and, where applicable, the Portfolios' Subadvisers, as well as the advisory, subadvisory, administrative and distribution arrangements for the Portfolios. In addition, one of the Independent Trustees and legal counsel to the Independent Trustees met several times with management and representatives of PricewaterhouseCoopers LLP ("PwC") to discuss management's proposed profitability methodology and made suggestions for changes to the methodology. As a result of management's focus on the profitability methodology and this series of meetings, the Independent Trustees received extensive information on UBS Global AM's profitability, a report from management on the methodology used and a report from PwC on industry practices with respect to profitability methodology. The board also received a summary prepared by the Trust's counsel of each Subadviser's responses to requests for due diligence materials in connection with the board's consideration of the approvals of the Subadvisory Agreements, including the Subadvisers' soft dollar and trade allocation practices and current litigation that might affect a Subadviser's performance of subadvisory services for the applicable Portfolio. The board also received materials detailing the administrative services provided to the Portfolios by UBS Global AM, which include providing accounting and financial analysis for the Portfolios, ensuring that all financial and tax regulatory reporting requirements were met, certifying required Securities and Exchange Commission documentation and monitoring the performance of the Portfolio's service providers.

The Independent Trustees also met for several hours the evening before the board meeting to discuss matters related to the Portfolios and other funds subject to their oversight and met again in executive session after management's presentation was completed to review the disclosure that had been made to them at the meeting. At all of these sessions the Independent Trustees met in session with their independent legal counsel. The Independent Trustees also received a memorandum from their independent legal counsel discussing the duties of board members in considering approval of advisory, subadvisory, administration and distribution agreements.

In its consideration of the approval of the Investment Management and Administration Agreement and the Subadvisory Agreements, the board considered the following factors:

Nature, extent and quality of the services under the Investment Management and Administration Agreement and the Subadvisory Agreements—The board received and considered information regarding the nature, extent and quality of management services provided to the Portfolios by UBS Global AM under the Investment Management and Administration Agreement (including in particular UBS Global AM's oversight of each Subadviser's provision of subadvisory services) and, for those Portfolios with Subadviser(s), subadvisory services provided by the particular Subadviser under the Subadvisory Agreements

341

during the past year. The board also considered the nature, extent and quality of administrative, distribution, and shareholder services performed by UBS Global AM and its affiliates for the Portfolios and the resources devoted to, and the record of compliance with, each Portfolio's compliance policies and procedures. The board noted that it received information at regular meetings throughout the year regarding the services rendered by UBS Global AM concerning the management of each Portfolio's affairs and UBS Global AM's role in coordinating providers of other services to the Portfolios, including custody, accounting and transfer agency services and, for each subadvised Portfolio, overseeing the Subadviser's provision of subadvisory services to the Portfolio. The board noted the complexity of this process for the Portfolios, given their broad range of investment strategies. The board noted that UBS Global AM provided extensive oversight of the Subadvisers for the Portfolios and reported to the board at each meeting on the Subadvisers' performance and made recommendations with respect to Subadviser changes from time to time based on the performance of the Subadvisers and certain other factors. The board's evaluation of the services provided by UBS Global AM and the Subadvisers took into account the board's knowledge and familiarity gained as board members of funds in the UBS New York fund complex, including the scope and quality of UBS Global AM's investment management and other capabilities and the quality of its administrative and other services. The board observed that the scope of services provided by UBS Global AM had expanded over time as a result of regulatory and other developments, including maintaining and monitoring its own and the Portfolios' expanded compliance programs.

The board had available to it the qualifications, backgrounds and responsibilities of each Portfolio's senior personnel at UBS Global AM and had received information regarding the person, persons or portfolio management team primarily responsible for the day-to-day portfolio management of each Portfolio and recognized that the Portfolios' senior personnel at UBS Global AM report to the board regularly, some at every board meeting, and that at each regular meeting the board receives a detailed report on each Portfolio's performance and receives more extensive information periodically from each Subadviser. The board also considered, based on its knowledge of UBS Global AM and its affiliates, the financial resources available to UBS Global AM and its parent organization, UBS AG. In that regard, the board received extensive financial information regarding UBS Global AM and noted that it was a wholly owned, indirect subsidiary of one of the largest financial services firms in the world. It was also noted that UBS Global AM had well over $100 billion in assets under management and was part of the UBS Global Asset Management Division, which had well over $700 billion of assets under management worldwide as of June 2007.

The board reviewed how transactions in Portfolio assets are effected. The board also reviewed, with respect to the non-money market Portfolios, brokerage policies and practices, the standards applied in seeking best execution, policies and practices regarding soft dollars, the use of a broker affiliated with UBS Global AM or a Subadviser and the existence of quality controls applicable to brokerage allocation procedures. In addition, UBS Global AM also reported to the board on, among other things, its disaster recovery plans and portfolio manager compensation plan.

The board concluded that, overall, it was satisfied with the nature, extent and quality of services provided (and expected to be provided) to the Portfolios under the Investment Management and Administration Agreement and, for the subadvised Portfolios, the Subadvisory Agreements.

Management and subadvisory fees and expense ratios—For each Portfolio, the board reviewed and considered the contractual management fee (each, a "Contractual Management Fee") payable by the Portfolio to UBS Global AM in light of the nature, extent and quality of the management and administrative services provided by UBS Global AM. The board also reviewed and considered the fee waiver and/or expense reimbursement arrangements currently in place for the Portfolio, if any, and considered the actual fee rate

342

UBS PACE Select Advisors Trust

Board Approvals of Investment Management and Administration Agreement and Subadvisory Agreements
(unaudited)

(after taking any waivers and reimbursements into account) (the "Actual Management Fee"). The board considered that UBS Global AM had entered into one or more fee waiver and/or expense reimbursement agreements with each Portfolio (except UBS PACE International Emerging Markets Equity Investments) under which UBS Global AM was contractually obligated to waive its management fees and/or reimburse the Portfolio so that the total ordinary operating expenses of certain or all classes of a given Portfolio through December 1, 2007 (excluding dividend expense, borrowing costs and/or interest expense, if any) would not exceed specified limits for each class (or, with respect to certain Portfolios an agreement to waive its management fee to the extent necessary to reflect the lower overall fees paid by UBS Global AM to one of the Portfolio's Subadvisers). The board also considered that each Portfolio with such a fee waiver/reimbursement a greement had agreed to repay UBS Global AM for those reimbursed expenses if the Portfolio can do so over the following three fiscal years without causing its expenses in any of those years to exceed the expense caps. Additionally, the board received and considered information comparing each Portfolio's Contractual Management Fee, Actual Management Fee and overall expenses with those of funds in a group of funds selected and provided by Lipper, Inc. ("Lipper"), an independent provider of investment company data (the "Expense Group"). Based on its review of the information provided by Lipper, the board expressed views regarding the comparative level of fees and/or expenses for certain of the Portfolios, particularly certain of the fixed-income Portfolios. Management responded to these views by proposing increased fee waiver/expense reimbursement arrangements for certain of the Portfolios to reduce these expenses, as described below. A discussion of the board's considerations with respect to each Portfolio's fe es is set forth below. (The footnotes to the financial statements appearing earlier in this annual report contain details regarding the expense caps and fee waiver arrangements for each Portfolio.)

Based on its review of the Lipper materials and the supplemental materials provided by UBS Global AM, the board discussed the relationship between the administration fees paid under the Investment Management and Administration Agreement and the total fees paid under such agreement. The board also discussed with UBS Global AM the relative level of the administration fee component versus administration fees paid by other funds with similar structures. UBS Global AM noted historical reasons for the current fee structure, including provisions contained in a regulatory grant of exemption received by the Trust. However, in light of the board's views, UBS Global AM stated that it would develop a formal proposal to submit to the board at a future date to change the structure of the fees. The proposal would also be expected to include reducing the overall contractual level of fees for certain funds by making permanent certain voluntary e xpense cap arrangements. UBS Global AM noted that if the board approved that future proposal, the changes would require shareholder approval. UBS Global AM and the board discussed using the opportunity of a shareholders' meeting to place certain other matters before investors, including possibly updating certain fundamental investment restrictions. UBS Global AM noted that if the board wanted to proceed in this manner, it would regard the costs related to the shareholders' meeting to be outside the current expense cap arrangements, which relate to ordinary Portfolio expenses. The board agreed and directed UBS Global AM to report back with a formal proposal, including draft proxy materials, at a future date.

In connection with its consideration of each Portfolio's management fees, the board also received information on UBS Global AM's standard institutional account fees for accounts of a similar investment type to each of the Portfolios. The board noted that, in general, these fees were lower than the Contractual Management Fees and Actual Management Fees for the Portfolios, but also noted management's explanation that comparisons with such accounts may be of limited relevance given the different structures and regulatory requirements of mutual funds versus such accounts and the differences in the levels of services required by mutual funds and such accounts. The board also received information on fees charged to other mutual funds managed by UBS Global AM. The board did not receive comparative information from Lipper with respect to the subadvisory fees for those Portfolios with Subadvisers in connection with its

343

UBS PACE Select Advisors Trust

Board Approvals of Investment Management and Administration Agreement and Subadvisory Agreements
(unaudited)

consideration of subadvisory fees. The board observed that it had received certain information regarding fees, profitability, compensation from other similar funds and economies of scale from certain Subadvisers as part of the summary of each Subadviser's responses to requests for due diligence materials in connection with the board's consideration of the approvals of the Subadvisory Agreements; however, the board also observed that the compensation paid to a Subadviser is paid by UBS Global AM, not the particular Portfolio and, accordingly, that the retention of a Subadviser does not increase the fees otherwise incurred by a Portfolio's shareholders.

Portfolio performance—For each Portfolio, the board received and considered (a) annualized total return information of the Portfolio compared to other funds (the "Performance Universe") selected by Lipper over the one-, three-, five-, ten- (or shorter for newer Portfolios) and since inception periods ended April 30, 2007 and (b) annualized performance information for each year in the ten-year (or shorter) period ended April 30, 2007. The board was provided with a description of the methodology Lipper used to determine the similarity of a Portfolio with the funds included in its Performance Universe. The board also considered UBS Global AM's statement that while management believed that the Lipper peer groups were useful in evaluating Portfolio expenses relative to peers, they were less useful in evaluating performance, as in many cases they were broad-based and consisted of funds that did not necessarily have similar investment parameters to the applicable Portfolio. The board also noted that it had received information throughout the year at periodic intervals with respect to each Portfolio's performance, including in most cases with respect to certain benchmark indices, including with respect to each Subadviser's performance. Further discussion of the board's considerations with respect to each Portfolio's performance is set forth below.

Adviser profitability—The board received and considered a profitability analysis of UBS Global AM and its affiliates in providing services to each Portfolio. The board also received profitability information with respect to the UBS New York fund complex as a whole. In addition, the board received information with respect to UBS Global AM's allocation methodologies used in preparing this profitability data, as noted above. UBS Global AM's profitability was considered not excessive in light of the nature, extent and quality of the services provided to the Portfolios. To the extent provided by Subadvisers, the board also reviewed information with respect to the Subadviser's profitability in providing services to the Portfolios. The board did not consider such Subadviser profitability information highly relevant as the subadvisory fees are paid by UB S Global AM, not by the relevant Portfolio.

Economies of scale—The board received and considered information from management regarding whether UBS Global AM realizes economies of scale as the Portfolios' assets grew beyond current levels, whether the Portfolios have appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale for the Portfolios. The board considered whether economies of scale in the provision of services to the Portfolios were being passed along to the shareholders. The board noted that, with the exception of UBS PACE Money Market Investments, each Portfolio's Contractual Management Fee contained breakpoints (with respect to the UBS PACE Large Co Value Equity Investments, the equivalent of breakpoints in the form of a permanent fee waiver which reduces the Contractual Management Fee as assets increase ). The board also noted that, with the exception of UBS PACE Small/Medium Co Value Equity Investments, UBS PACE Small/Medium Co Growth Equity Investments, UBS PACE International Emerging Markets Equity Investments, UBS PACE Alternative Strategies Investments, UBS PACE High Yield Investments and UBS PACE Global Real Estate Securities Investments, each Portfolio's asset level exceeded its first breakpoint. Accordingly, the board determined that actual economies of scale existed for those Portfolios whose assets had reached the first breakpoint level and potential economies of scale existed for those Portfolios whose assets had not yet reached their first breakpoint level. The board also noted that to the extent a Portfolio's assets have increased over time, it has

344

UBS PACE Select Advisors Trust

Board Approvals of Investment Management and Administration Agreement and Subadvisory Agreements
(unaudited)

realized other economies of scale as certain expenses, such as fees for Trustees, auditor and legal fees and printing and postage, become a smaller percentage of overall assets. The board also took note of the relationship between any breakpoints in a subadvisory fee and the breakpoints in fees paid by the Portfolios to UBS Global AM.

Generally, in light of UBS Global AM's profitability data, the Actual Management Fee, the Contractual Management Fee and the breakpoints currently in place for most of the Portfolios, the board believed that UBS Global AM's sharing of potential and current economies of scale with the Portfolios was acceptable.

Other benefits to UBS Global AM and the Subadvisers—The board considered other benefits received by UBS Global AM and its affiliates as a result of its relationship with the Portfolios, including the opportunity to offer additional products and services to Portfolio shareholders. The board was informed by management that the subadvisers' relationships with the sub-advised Portfolios were limited to their provision of subadvisory services to these Portfolios, and that therefore, management believed that the Subadvisers did not receive tangible ancillary benefits as a result of their relationships with the subadvised Portfolios, with the exception of possible benefits from soft dollars for the equity Portfolios (which would also potentially benefit such Portfolios). The board recognized that certain Subadvisers could receive intangible benefits fro m their association with the Trust, such as increased name recognition or publicity from being selected as Subadvisers to the Trust after an extensive review process. Similarly, a Portfolio could benefit from having a Subadviser with an established or well-regarded reputation.

In light of the costs of providing investment management, administrative and other services to the Portfolios and UBS Global AM's ongoing commitment to the Portfolios, the profits and other ancillary benefits that UBS Global AM and its affiliates received were considered reasonable.

In the discussions that follow, reference is made to "quintile" placement in Lipper expense group and performance universe categories. With respect to expenses, the first quintile represents that fifth of the funds in the Expense Group with the lowest fees or expenses, as applicable, and the fifth quintile represents that fifth of the funds in the Expense Group with the highest fees or expenses, as applicable. With respect to performance, the first quintile represents that fifth of the funds in the Performance Universe with the best relative performance, and the fifth quintile represents that fifth of the funds in the Performance Universe with the worst relative performance.

UBS PACE Government Securities Fixed Income Investments

In approving the Investment Management and Administration Agreement and the Subadvisory Agreement with Pacific Investment Management Company LLC ("PIMCO"), the board, including the Independent Trustees, also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio's performance was in the second quintile for the one-year period and since inception, the first (i.e., top) quintile for the three-year period and at the median for the five-year period. Based on its review, the board concluded that the Portfolio's investment performance was satisfactory.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee was in the second quintile and its Actual Management Fee and total expenses were in the fifth quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. The board expressed its views regarding the level of expenses, and

345

(unaudited)

management proposed an increased expense cap for each class of the Portfolio so that the ordinary total operating expenses of each class of the Portfolio (excluding dividend expense, borrowing costs and interest expense, if any) would not exceed 1.07% for Class A, 1.82% for Class B, 1.57% for Class C, 0.82% for Class Y and 0.82% for Class P through November 30, 2008. Management also proposed that effective August 1, 2007, UBS Global AM would waive its management fees to the extent necessary to reflect a lower subadvisory fee to be paid by UBS Global AM to PIMCO, if the board approved a new Subadvisory Agreement with PIMCO that offered a fee reduction, which was also under consideration. Based on its review and management's proposals, the board determined that the management fee and the subadvisory fee were reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Managem ent and Administration Agreement and the Subadvisory Agreement (as proposed to be revised), respectively.

UBS PACE Intermediate Fixed Income Investments

In approving the Investment Management and Administration Agreement and the Subadvisory Agreement with BlackRock Financial Management, Inc., the board, including the Independent Trustees, also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio's performance was at the median for the one- and three-year periods and in the fifth quintile for the five-year period and since inception, showing overall that the Portfolio's performance relative to its Performance Universe had improved over time. Based on its review, the board concluded that the Portfolio's investment performance was satisfactory.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee was at the median and its Actual Management Fee and total expenses were in the fifth quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. The board expressed its views regarding the level of expenses, and management proposed an increased expense cap for each class of the Portfolio so that the ordinary total operating expenses of each class of the Portfolio (excluding dividend expense, borrowing costs and interest expense, if any) would not exceed 0.93% for Class A, 1.68% for Class B, 1.43% for Class C, 0.68% for Class Y and 0.68% for Class P through November 30, 2008. Based on its review and management's proposal, the board determined that the management fee and the subadvisory fee were reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Management and Administration Agreement and the Subadvisory Agreement, respectively.

UBS PACE Strategic Fixed Income Investments

In approving the Investment Management and Administration Agreement and the Subadvisory Agreement with PIMCO, the board, including the Independent Trustees, also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio's performance was at the median for the one- and three-year periods and the second quintile for the five-year period and since inception. Management noted that the Portfolio's relative performance in comparison to its Performance Universe had improved over the past year as the Portfolio benefited from PIMCO's long duration positioning over a majority of the year. Based on its review, the board concluded that the Portfolio's investment performance was satisfactory.

346

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee was in the fourth quintile and its Actual Management Fee and total expenses were in the fifth quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. The board expressed its views regarding the level of expenses, and management proposed an increased expense cap for each class of the Portfolio so that the ordinary total operating expenses of each class of the Portfolio (excluding dividend expense, borrowing costs and interest expense, if any) would not exceed 1.06% for Class A, 1.81% for Class B, 1.56% for Class C, 0.81% for Class Y and 0.81% for Class P through November 30, 2008. Based on its review and management's proposal, the board determined that the managemen t fee and the subadvisory fee were reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Management and Administration Agreement and the Subadvisory Agreement, respectively.

UBS PACE Municipal Fixed Income Investments

In approving the Investment Management and Administration Agreement and the Subadvisory Agreement with Standish Mellon Asset Management Company LLC, the board, including the Independent Trustees, also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio's performance was in the fifth quintile for the one-year period, the five-year period and since inception and the fourth quintile for the three-year period. The board questioned management about the Portfolio's performance. UBS Global AM noted that the Portfolio was being managed with a shorter duration than many other funds in its peer group and that this more conservative positioning impacted performance over the longer term. It was also noted that the Board had approved changing the Portfolio's benchmark to the Lehman Brothers Municipal 3-15 Year Index at the May 2007 meeting and that the Portfolio's duration positioning after this change should be more in line with its current peer group. Based on its review and management's explanation, the board concluded tha t the Portfolio's investment performance was satisfactory.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee and Actual Management Fee were in the fourth quintile and its total expenses were in the fifth quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. The board expressed its views regarding the level of expenses, and management proposed an increased expense cap for each class of the Portfolio so that the ordinary total operating expenses of each class of the Portfolio (excluding dividend expense, borrowing costs and interest expense, if any) would not exceed 0.93% for Class A, 1.68% for Class B, 1.43% for Class C, 0.68% for Class Y and 0.68% for Class P through November 30, 2008. Based upon its review and management's proposal, the board determined that the manage ment fee and the subadvisory fee were reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Management and Administration Agreement and the Subadvisory Agreement, respectively.

and since inception. Management noted that the Portfolio is compared to a peer group which includes both currency hedged and currency unhedged investment styles and both "global" and "international" fixed income managers. Management also explained that both subadvisers had underperformed the benchmark for the one-year period. Management believed Rogge's under-performance was due to its underweight in Japanese bonds and its overweight to dollar bloc currencies versus Asian currencies. Management also noted it was recommending the termination of the Portfolio's other Subadviser (because in part of the departure of certain investment advisory personnel from the Subadviser) and that Rogge would become the sole Subadviser and employ additional strategies, which management believed could improve performance. Based on its review and management's explanation, the board concluded that the Portfolio's investment performance was satisfacto ry.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee, Actual Management Fee and total expenses were each in the fifth quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. The board expressed its views regarding the level of expenses, and management proposed a fee waiver and increased expense cap for each class of the Portfolio so that the ordinary total operating expenses of each class of the Portfolio (excluding dividend expense, borrowing costs and interest expense, if any) would not exceed 1.25% for Class A, 2.00% for Class B, 1.75% for Class C, 1.00% for Class Y and 1.00% for Class P through November 30, 2008. These ratios reflected management's proposal that effective August 1, 2007, UBS Global AM would waive its management fees to the extent necessary to reflect the lower subadvisory fee negotiated with Rogge and to be paid by UBS Global AM to Rogge effective August 23, 2007 (such lower subadvisory fees to be reflected in a new Subadvisory Agreement with Rogge). Based on its review and taking into account management's proposals, the board determined that the management fee and the subadvisory fee were reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Management and Administration Agreement and the Subadvisory Agreement (as proposed to be revised), respectively. The board also agreed that the Subadvisory Agreement with the Portfolio's other Subadvisor, Fischer Francis Trees & Watts, Inc. (and affiliates) would continue to the extent necessary to facilitate the orderly termination of its Subadvisory Agreement and transition of its segment of the Portfolio to Rogge.

Based on its review, the board concluded that the Portfolio's investment performance was satisfactory.

Management and subadvisory fees and expense ratios—In addition to the fee waiver/reimbursement agreement (in the form of a contractual agreement) for this Portfolio, the board also considered that UBS Global AM is contractually obligated to waive its management fee to the extent necessary to reflect the lower overall fees paid by UBS Global AM to SSgA. The comparative Lipper information showed that the Portfolio's Contractual Management Fee was in the fourth quintile but that its Actual Management Fee was in the third quintile and total expenses were in the second quintile in the Portfolio's Expense Group for the

Background—In approving the Investment Management and Administration Agreement and the Subadvisory Agreements with each of Ariel Capital Management, LLC ("Ariel"), Metropolitan West Capital Management, LLC ("MetWest Capital") and Opus Capital Management, Inc. ("Opus"), the board, including the Independent Trustees also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio's performance was in the second quintile for the one-year period and in the fifth quintile for the three- and five-year periods and since inception. Management noted that the Portfolio's improvement relative to its Performance Universe was primarily due to the performance of MetWest Capital during the one-year period. Based on its review, the board concluded that the Portfolio's investment performance was acceptable, but noted that further information on the Portfolio's performance in the future could be expected to be subject to heightened scrutiny.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee and Actual Management Fee were in the third quintile and that its total expenses were in the first quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report.

performance had improved over the one-year period due to the outperformance of both of the Subadvisers. Based on its review, the board concluded that the Portfolio's investment performance was satisfactory.

UBS PACE High Yield Investments

In approving the Investment Management and Administration Agreement and the Subadvisory Agreement with MacKay Shields LLC ("MacKay Shields"), the board, including the Independent Trustees, also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio was in the fifth quintile for the period since inception in April 2006. The board questioned management about the Portfolio's underperformance. Management noted that the Portfolio's performance was due to several factors, including MacKay Shield's security selection and sector allocation (which emphasized less risky investments as opposed to many of the Portfolio's peers, which generally took more risk); that the Portfolio, which commenced operations in April 2006 and had relatively large amounts of cash inflows in comparison to its size, throughout this initial inception period held more cash than it was expected to hold going forward; and that the rapid growth of the Portfolio's assets put the Portfolio in a near-constant buying mode, with the result that the Por tfolio paid the "ask" price for securities while valuing them at the "bid" price, with a compounding impact to performance, which management anticipated could abate if the purchase of additional securities represented a smaller percentage of the Portfolio's assets if the Portfolio grew in the future. Based on its review and management's explanation, the board concluded that the Portfolio's investment performance during its initial period since inception had been acceptable.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee was in the fourth quintile, its Actual Management Fee was in the first quintile and its total expenses were in the fifth quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. The board recognized that the Portfolio's small size in comparison to its peers in its Expense Group may have had an effect on its comparative ranking with respect to expenses. Taking this into account, the board determined that the management fee and the subadvisory fee were reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Management and Administration Agreement and the Subadvisory Agreement, respectively.

UBS PACE Alternative Strategies Investments

In approving the Investment Management and Administration Agreement and the Subadvisory Agreements with each of Analytic Investors, Inc. ("Analytic") and Wellington Management Company, LLP ("Wellington"), the board, including the Independent Trustees also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio's performance was at the median for the one-year period. Based on its review, the board concluded that the Portfolio's investment performance for this initial period had been acceptable.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee, Actual Management fee and total expenses were in the fifth quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. Management discussed with the board the heterogeneous nature of the relatively small Lipper Expense Group Universe. In light of the complex strategies employed by the Portfolio, the board determined that the management fee and the subadvisory fee paid to each of Analytic and Wellington were reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Management and Administration Agreement and the Subadvisory Agreements, respectively.

Approval of Goldman Sachs Asset Management, L.P. ("GSAM") as a new Subadviser to UBS PACE Alternative Strategies Investments

UBS Global AM also requested that the board approve the addition of GSAM as a new Subadviser to the Portfolio. In addition to the factors described above, to the extent applicable to the approval of a new subadviser, the board also considered management's reasons for proposing GSAM as an additional Subadviser for the Portfolio, including that management believed GSAM's strategy would have a low correlation to the strategies currently employed by the other two Subadvisers to the Portfolio, and how the fixed-income orientation GSAM would bring to the Portfolio could correlate with the general equity, currency and options strategies of the other two Subadvisers, possibly resulting in reduced volatility for the Portfolio. The board also received materials from GSAM detailing its portfolio management team, organization and investment strategy and portfolio selection process. The board concluded that, overall, it was satisfied with th e nature, extent and quality of services expected to be provided to the Portfolio under the proposed subadvisory agreement. The board reviewed and considered the proposed contractual subadvisory fee to be payable by UBS Global AM in light of the nature, extent and quality of the subadvisory services anticipated to be provided by GSAM. The board considered that the compensation to be paid to GSAM would be paid by UBS Global AM, not the Portfolio and, accordingly, that in any event the retention of GSAM would not change the fees otherwise incurred by the Portfolio's shareholders. Taking all of the above into consideration, the board determined that the proposed subadvisory fee was reasonable in

352

(unaudited)

light of the nature, extent and quality of the services proposed to be provided to the Portfolio under the subadvisory agreement. The board was informed by management that GSAM's relationship with the Portfolio would be limited to its provision of subadvisory services to the Portfolio and that therefore management believed that GSAM did not receive tangible ancillary benefits as a result of its relationship with the Portfolio, with the exception of possible benefits from soft dollars for the Portfolio (which would also potentially benefit the Portfolio). The board noted that, as GSAM would be a new Subadviser to the Portfolio, the current performance of the Portfolio was not relevant to the consideration of the approval of the subadvisory agreement. Profitability of UBS Global AM or its affiliates in providing services to the Portfolio was not a factor considered by the board, as the subadvisory fee would be paid by UBS Global A M out of the management fee paid to it by the Portfolio, and not by the Portfolio. The board also considered that, as the subadvisory fee for the Portfolio would be paid by UBS Global AM, not by the Portfolio, consideration of economies of scale with respect specifically to the subadvisory fee were not relevant. In light of all of the foregoing, the board approved the proposed subadvisory agreement with GSAM for the Portfolio to become effective later in 2007.

UBS PACE Global Real Estate Securities Investments

In approving the Investment Management and Administration Agreement and the Subadvisory Agreement with GSAM, the board, including the Independent Trustees, also considered the following factors:

Portfolio performance—The comparative Lipper information showed that the Portfolio's performance was in the first quintile since inception. Based on its review, the board concluded that the Portfolio's investment performance for this initial period had been acceptable.

Management and subadvisory fees and expense ratios—The comparative Lipper information showed that the Portfolio's Contractual Management Fee and total expenses were in the second quintile and its Actual Management Fee was in the first quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report. The board determined that the management fee and the subadvisory fee paid to GSAM was reasonable in light of the nature, extent and quality of the services provided to the Portfolio under the Investment Management and Administration Agreement and the Subadvisory Agreement, respectively.

In light of all of the foregoing, the board approved the Investment Management and Administration Agreement for each Portfolio and, for those Portfolios with Subadvisers, the Subadvisory Agreement(s) to continue for another year, except as otherwise noted above.

No single factor reviewed by the board was identified by the board as the principal factor in determining whether to approve the Investment Management and Administration Agreement or, for the subadvised Portfolios, the Subadvisory Agreements. The Independent Trustees were advised by separate independent legal counsel throughout the process. The board discussed the proposed continuance of the Investment Management and Administration Agreement and the Subadvisory Agreements in a private session with their independent legal counsel at which no representatives of UBS Global AM or the Subadvisers were present.

Annual Report
July 31, 2007

UBS PACE Money Market Investments

September 19, 2007

Dear Shareholder,

Performance

For the fiscal year ended July 31, 2007, the Portfolio returned 4.86% (before the deduction of the maximum UBS PACE program fee; after the deduction of the maximum UBS PACE program fee, the Portfolio returned 3.29%). In comparison, the 90-Day US T-Bill Index (the "Index") returned 5.06%, and the median return for the Lipper Money Market Funds category was 4.68%. (Returns over various time periods are shown in the "Performance at a glance" table on page 5. Please note that the returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions.)

Market Review

US economic growth was mixed during the fiscal year. After expanding 2.4% in the second quarter of 2006, gross domestic product (GDP) grew 1.1% and 2.1% in the third and fourth quarters of the calendar year, respectively. The economy then weakened further during the first quarter of 2007, with GDP growing a modest 0.6%. This was attributed, in part, to the faltering housing market. The economy then appeared to rebound in the second quarter, as the preliminary estimate for GDP growth came in at 4.0%.

Investment Advisor:

UBS Global Asset Management (Americas) Inc.

Portfolio Manager:

Michael H. Markowitz

Objective:

Current income consistent with preservation of capital and liquidity

Investment process:

The Portfolio is a money market mutual fund and seeks to maintain a stable price of $1.00 per share, although it may be possible to lose money by investing in this Portfolio. The Portfolio invests in a diversified portfolio of high-quality money market instruments of governmental and private issuers. Security selection is based on the assessment of relative values and changes in market and economic conditions.

UBS PACE Money Market Investments

Just prior to the start of the review period, the Federal Reserve Board (the "Fed") raised the federal funds rate by 25 basis points (0.25%)—bringing it to 5.25%—where it remained throughout 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.) The Fed has repeatedly indicated that future rate movements would be data-dependent, as it attempts to ward off inflation and to keep the economy growing at a reasonable pace.

Following the conclusion of the reporting period, the Fed reacted to concerns over subprime lending (a type of lending that relies on risk-based pricing to serve borrowers who cannot obtain credit in the prime market) by providing greater amounts of liquidity to the market in order to facilitate normal market operations. The Fed followed this up by lowering the fed funds rate by 0.50%, bringing it to 4.75%, at its September 18, 2007 meeting.

The Fed has stated that it plans to continue monitoring the risks of rising inflation along with the potential for slower economic growth.

Portfolio Performance

We initially focused on securities with maturities of three to six months, as the future direction of short-term interest rates was uncertain. This strategy allowed us to take advantage of the yield curve position, which was inverted for most of the period, and to lock in higher yields, while at the same time insulating the Portfolio to some degree from a possible Fed rate cut. (An inverted yield curve environment is one in which long-term debt instruments have a lower yield than short-term debt instruments of the same credit quality.)

Later in the fiscal year, we began using a "barbell" strategy (in which the maturities of securities in a portfolio are concentrated at opposite ends of the short-term yield curve). While we continued to buy shorter-term securities, we also sought to extend the Portfolio's weighted average maturity with longer-term money market securities maturing within nine to 13 months. This was beneficial to performance, as the yield on one-year money market securities rose steadily higher late in the reporting period.

As always, quality, liquidity and yield remained paramount in our selection process for the Portfolio. We maintained relatively large

UBS PACE Money Market Investments

positions in commercial paper (a short-term security often backed by a guarantee or a letter of credit from a bank or other entity), although we decreased this somewhat over the reporting period. Other short-term corporate obligations and certificates of deposit also comprised a fair amount of the Portfolio. Within these sectors, we found variable-rate securities, which offer interest rates that reset periodically, to be attractive, given the uncertainty of interest rate movements by the Fed. We purchased variable-rate securities linked to the fed funds rate, as well as those linked to the one-month and three-month LIBOR. (The LIBOR, or the London Interbank Offered Rate, is among the most common of benchmark interest rate indexes used to make adjustments to adjustable-rate securities.)

As always, we thank you for your continued support and welcome any comments or questions you may have.

Sincerely,

Kai R. Sotorp President UBS PACE Select Advisors Trust Head of the Americas UBS Global Asset Management (Americas) Inc.	Michael H. Markowitz Portfolio Manager UBS PACE Money Market Investments Managing Director UBS Global Asset Management (Americas) Inc.

For UBS PACE Money Market Investments, average annual total returns for periods ended June 30, 2007, after deduction of the maximum UBS PACE program fee, were as follows: 1-year period, 3.29%; 5-year period, 0.81%; 10-year period, 1.97%.

For UBS PACE Money Market Investments, the 7-day current yield for the period ended July 31, 2007 was 4.72% (without maximum UBS PACE program fee and after fee waivers and/or expense reimbursements; the yield was 4.40% before fee waivers and/or expense reimbursements). With the maximum UBS PACE program fee, the 7-day current yield was 3.22% after fee waivers and/or expense reimbursements; the yield was 2.90% before fee waivers and/or expense reimbursements. The Portfolio's yield quotation more closely reflects the current earnings of the Portfolio than the total return quotation. Yields will fluctuate and reflect fee waivers.

1  The maximum annual UBS PACE program fee is 1.5% of the value of UBS PACE assets.

2  90-Day US T-Bills are promissory notes issued by the US Treasury and sold through competitive bidding, with a short-term maturity date, in this case, of three months. This Index is derived from secondary market interest rates as published by the Federal Reserve Bank.

Past performance does not predict future performance and the performance information provided does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions. The return of an investment will fluctuate. Performance results assume reinvestment of all dividends and capital gain distributions at net asset value on the payable dates.

Understanding your Portfolio's expenses (unaudited)

As a shareholder of the Portfolio, you incur two types of costs: (1) ongoing program fees; and (2) ongoing Portfolio costs, including management fees and other Portfolio expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolio 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, February 1, 2007 to July 31, 2007.

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 Portfolio's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Portfolio'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 Portfolio 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.

Understanding your Portfolio's expenses (unaudited)
(concluded)

Please note that the expenses shown in the table are meant to highlight your ongoing Portfolio costs only and do not reflect any program fees. Therefore, the second line in the table is useful in comparing ongoing Portfolio costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these program fees were included, your costs would have been higher.

		Beginning account value February 1, 2007		Ending account value July 31, 2007		Expenses paid during period102/01/07 to 07/31/07		Expense ratio during the period
Class P	Actual	$	1,000.00	$	1,023.80	$	3.01		0.60	%
	Hypothetical (5% annual return before expenses)		1,000.00		1,021.82		3.01		0.60	%

1  Expenses are equal to the Portfolio's annualized net expense ratio, multiplied by the average account value over the period, multiplied by 181 divided by 365 (to reflect the one-half year period).

Organization and significant accounting policies

UBS PACE Money Market Investments (the "Portfolio") is a diversified portfolio of UBS PACE Select Advisors Trust (the "Trust"), which was organized as a Delaware statutory trust under the laws of the State of Delaware by Certificate of Trust dated September 9, 1994, as amended June 9, 1995 and thereafter, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended, as an open-end management investment company. The trustees of the Trust have authority to issue an unlimited number of shares of beneficial interest, par value $0.001 per share.

The Trust currently offers fifteen Portfolios available for investment, each having its own investment objectives and policies. Shares of the Portfolio currently are available only to participants in the UBS PACE^SM Select Advisors Program and the UBS PACE^SM Multi Advisor Program.

The Trust accounts separately for the assets, liabilities and operations of each Portfolio. Expenses directly attributable to each Portfolio are charged to that Portfolio's operations; expenses which are applicable to all Portfolios are allocated among them on a pro rata basis.

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

The preparation of financial statements in accordance with US generally accepted accounting principles requires the Portfolio's management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements.

18

UBS PACE Money Market Investments

Notes to 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 Trust's Board of Trustees (the "Board") determines that this does not represent fair value. Periodic review and monitoring of the valuation of the securities held by the Portfolio 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 on 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 July 31, 2007, 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 c ertain measurements reported on the Statement of operations for a fiscal period.

Repurchase agreements—The Portfolio may purchase securities or other obligations from a bank or securities dealer (or its affiliate), subject to the seller's agreement to repurchase them at an agreed upon date (or upon demand) and price. The Portfolio maintains custody of the underlying obligations prior to their repurchase, either through its regular custodian or through a

19

UBS PACE Money Market Investments

Notes to financial statements

special "tri-party" custodian or sub-custodian that maintains a separate account for both the Portfolio 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 Portfolio 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 Portfolio may suffer delays, costs and possible losses in connection with the disposition or retention of the collateral. Under certain circumstances, in the e vent 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 Portfolio 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").

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 debt securities held by the Portfolio to meet their obligations may be affected by economic and political developments, including those particular to a specific industry, country, state or region.

20

UBS PACE Money Market Investments

Notes to financial statements

Investment manager and administrator

The Board has approved an investment management and administration contract ("Management Contract") with UBS Global AM. In accordance with the Management Contract, the Portfolio pays UBS Global AM an investment management and administration fee, which is accrued daily and paid monthly, at an annual rate of 0.35% of the Portfolio's average daily net assets. At July 31, 2007, the Portfolio owed UBS Global AM $127,236 for investment management and administration fees.

UBS Global AM has contractually undertaken to waive a portion of the Portfolio's investment management and administration fees and/or reimburse a portion of the Portfolio's other expenses, when necessary, to maintain the total annual ordinary operating expenses (excluding interest expense, if any) at a level not exceeding 0.60% through December 1, 2007. The Portfolio will make a payment to UBS Global AM for any previously reimbursed expenses during the following three fiscal years to the extent that operating expenses are otherwise below the expense cap. For the year ended July 31, 2007, UBS Global AM reimbursed the Portfolio for non-management fee expenses totaling $1,199,238. At July 31, 2007, UBS Global AM owed the portfolio $116,650 for expense reimbursements.

At July 31, 2007, the Portfolio had expense reimbursements subject to repayment and respective dates of expiration as follows:

Expense reimbursements subject to repayment		Expires July 31, 2008		Expires July 31, 2009		Expires July 31, 2010
$	3,033,137	$	718,836	$	1,115,063	$	1,199,238

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 trustee of the Portfolio. The Portfolio has been informed that Professor Feldberg's role at Morgan Stanley

21

UBS PACE Money Market Investments

Notes to financial statements

does not involve matters directly affecting any UBS funds. Portfolio transactions are executed through Morgan Stanley based on that firm's ability to provide best execution of the transactions. During the year ended July 31, 2007, the Portfolio purchased and sold certain securities (e.g., fixed income securities) in principal trades with Morgan Stanley having an aggregate value of $397,121,308. 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 Portfolio's investment manager, it is believed that under normal circumstances it represents a small portion of the total value of the transactions.

Transfer agency related services fees

UBS Financial Services Inc. provides transfer agency related services to the Portfolio pursuant to a delegation of authority from PFPC Inc. ("PFPC"), the Portfolio's transfer agent, and is compensated for these services by PFPC, not the Portfolio.

For the year ended July 31, 2007, UBS Financial Services Inc. received from PFPC, not the Portfolio, $847,540 of the total transfer agency and related services fees paid by the Portfolio to PFPC.

Other liabilities and components of net assets

At July 31, 2007, the Portfolio had the following liabilities outstanding:

Payable for shares of beneficial interest repurchased	$	2,911,812
Dividends payable to shareholders		821,317
Other accrued expenses*		537,655

* Excludes investment management and administration fees.

22

UBS PACE Money Market Investments

Notes to financial statements

At July 31, 2007, the components of net assets were as follows:

Accumulated paid in capital	$	408,562,941
Accumulated net realized loss from investment activities		(599	)
Net assets	$	408,562,342

Federal tax status

The Portfolio intends to distribute 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 its net investment income, net realized capital gains and certain other amounts, if any, the Portfolio intends not to be subject to a federal excise tax.

The tax character of distributions paid during the fiscal years ended July 31, 2007 and July 31, 2006 was ordinary income.

At July 31, 2007 the components of accumulated earnings on a tax basis were undistributed ordinary income of $821,317 and accumulated realized capital and other losses of $599.

At July 31, 2007, the Portfolio has a net capital loss carryforward of $449. This loss carryforward is available as a reduction, to the extent provided in the regulations, of any future net realized capital gains; $272 will expire by July 31, 2014 and $177 will expire by July 31, 2015. During the fiscal year, $161 of capital loss carryforwards expired unutilized.

In accordance with US Treasury regulations, the Fund has elected to defer realized capital losses of $150 arising after October 31, 2006. Such losses are treated for tax purposes as arising on August 1, 2007.

To reflect reclassifications arising from permanent "book/tax" differences for the year ended July 31, 2007, beneficial interest was decreased by $161 and accumulated net realized loss was

23

UBS PACE Money Market Investments

Notes to financial statements

decreased by $161. These differences are primarily due to the expiration of capital loss carryforwards.

On July 13, 2006, FASB released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing a fund's tax return to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet a more-likely-than-not threshold would be recorded as a tax expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Based on the Secu rities and Exchange Commission's announcement on December 22, 2006, the implementation of FIN 48 must be incorporated into accounting practices no later than the last business day that occurs in the period covered by the Portfolio's January 31, 2008 semiannual report. Management continues to evaluate the application of FIN 48 to the Portfolio, and is not in a position at this time to estimate the significance of its impact, if any, on the Portfolio's financial statements.

Shares of beneficial interest

There is an unlimited amount of $0.001 par value shares of beneficial interest authorized. Transactions in shares of beneficial interest, at $1.00 per share, were as follows:

	For the years ended July 31,
	2007			2006
Shares sold		424,841,805			348,451,721

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 us ed and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2007, by correspondence with the custodian and others, or by other appropriate auditing procedures where replies from others were not received.

Board approval of investment management and administration agreement during the period February 1, 2007 through July 31, 2007 (unaudited)

Background—At a meeting of the UBS PACE Select Advisors Trust's (the "Trust") board on July 18, 2007, the members of the board, including the Trustees who are not "interested persons" of the Trust ("Independent Trustees"), as defined in the Investment Company Act of 1940, as amended (the "1940 Act"), considered and approved the continuance of the Investment Management and Administration Agreement between UBS Global Asset Management (Americas) Inc. ("UBS Global AM") and the Trust, on behalf of UBS PACE Money Market Investments (the "Portfolio"). In preparing for the meeting, the board members had requested and received extensive information from UBS Global AM to assist them, including performance and expense information for other investment companies with similar investment objectives to the Portfolio. The board received and considered a variety o f information about UBS Global AM , as well as the advisory, administrative and distribution arrangements for the Portfolio. In addition, one of the Independent Trustees and legal counsel to the Independent Trustees met several times with management and representatives of PricewaterhouseCoopers LLP ("PwC") to discuss management's proposed profitability methodology and made suggestions for changes to the methodology. As a result of management's focus on the profitability methodology and this series of meetings, the Independent Trustees received extensive information on UBS Global AM's profitability, a report from management on the methodology used and a report from PwC on industry practices with respect to profitability methodology. The board also received materials detailing the administrative services provided to the Portfolio by UBS Global AM, which include providing accounting and financial analysis for the Portfolio, ensuring that all financial and tax regulatory reporting requirements were met, certifyi ng required Securities and Exchange Commission documentation and monitoring the performance of the Portfolio's service providers.

The Independent Trustees also met for several hours the evening before the board meeting to discuss matters related to the Portfolio and other funds subject to their oversight and met again in

Board approval of investment management and administration agreement during the period February 1, 2007 through July 31, 2007 (unaudited)

executive session after management's presentation was completed to review the disclosure that had been made to them at the meeting. At all of these sessions the Independent Trustees met in session with their independent legal counsel. The Independent Trustees also received a memorandum from their independent legal counsel discussing the duties of board members in considering approval of advisory, administration and distribution agreements.

In its consideration of the approval of the Investment Management and Administration Agreement, the board considered the following factors:

Nature, extent and quality of the services under the investment management and administration agreement—The board received and considered information regarding the nature, extent and quality of management services provided to the Portfolio by UBS Global AM under the Investment Management and Administration Agreement during the past year. The board also considered the nature, extent and quality of administrative, distribution, and shareholder services performed by UBS Global AM and its affiliates for the Portfolio and the resources devoted to, and the record of compliance with, the Portfolio's compliance policies and procedures. The board noted that it received information at regular meetings throughout the year regarding the services rendered by UBS Global AM concerning the management of the Portfolio's affairs and UBS Global AM's role in coordin ating providers of other services to the Portfolio, including custody, accounting and transfer agency services. The board's evaluation of the services provided by UBS Global AM took into account the board's knowledge and familiarity gained as board members of funds in the UBS New York fund complex, including the scope and quality of UBS Global AM's investment management and other capabilities and the quality of its administrative and other services. The board observed that the scope of services provided by UBS Global AM had expanded over time as a result of regulatory and other developments, including maintaining and monitoring the expanded compliance programs for the Portfolio and the other series of the Trust.

The board had available to it the qualifications, backgrounds and responsibilities of the Portfolio's senior personnel at UBS Global AM and had received information regarding the persons primarily responsible for the day-to-day portfolio management of the Portfolio and recognized that the Portfolio's senior personnel at UBS Global AM report to the board regularly, some at every board meeting, and that at each regular meeting the board receives a detailed report on the Portfolio's performance. The board also considered, based on its knowledge of UBS Global AM and its affiliates, the financial resources available to UBS Global AM and its parent organization, UBS AG. In that regard, the board received extensive financial information regarding UBS Global AM and noted that it was a wholly own ed, indirect subsidiary of one of the largest financial services firms in the world. It was also noted that UBS Global AM had well over $100 billion in assets under management and was part of the UBS Global Asset Management Division, which had well over $700 billion of assets under management worldwide as of June 2007. The board reviewed how transactions in Portfolio assets are effected. In addition, UBS Global AM also reported to the board on, among other things, its disaster recovery plans and portfolio manager compensation plan.

The board concluded that, overall, it was satisfied with the nature, extent and quality of services provided (and expected to be provided) to the Portfolio under the Investment Management and Administration Agreement.

Management fees and expense ratios—The board reviewed and considered the contractual management fee ("Contractual Management Fee") payable by the Portfolio to UBS Global AM in light of the nature, extent and quality of the management and administrative services provided by UBS Global AM. The board also reviewed and considered the fee waiver arrangement currently in place for the Portfolio, and considered the actual fee rate (after taking any waivers and reimbursements into account) (the "Actual Management

30

UBS PACE Money Market Investments

Board approval of investment management and administration agreement during the period February 1, 2007 through July 31, 2007 (unaudited)

Fee"). The board considered that UBS Global AM had entered into an agreement with the Portfolio under which UBS Global AM was contractually obligated to waive its management fees and/or reimburse the Portfolio so that the total ordinary operating expenses of the Portfolio through December 1, 2007 (excluding interest expense, if any) would not exceed a specified limit. The board also considered that the Portfolio had agreed to repay UBS Global AM for those reimbursed expenses if the Portfolio can do so over the following three fiscal years without causing its expenses in any of those years to exceed the expense caps. Additionally, the board received and considered information comparing the Portfolio's Contractual Management Fee, Actual Management Fee and overall expenses with those of funds in a group of funds selected and provided by Lipper, Inc. ("Lipper"), an independent provider of investment company data (the "Expense Group" ). The board received information from UBS Global AM with respect to fees paid by institutional or separate accounts but, in management's view, such fee information was not very relevant to the Portfolio because, for among other reasons, separately managed and institutional accounts with a "cash" mandate were not subject to the constraints of Rule 2a-7 under the 1940 Act to which the Portfolio is subject and, therefore, were not comparable. The comparative Lipper information showed that the Portfolio's Contractual Management Fee and Actual Management Fee were in the first quintile and its total expenses were in the second quintile in the Portfolio's Expense Group for the comparison periods utilized in the Lipper report (with the first quintile representing that fifth of the funds in the Expense Group with the lowest fees or expenses, as applicable). The board determined that the management fee was reasonable in light of the nature, extent and quality of the services provided to the Portfolio.

Portfolio performance—The board received and considered (a) annualized total return information of the Portfolio compared to other funds (the "Performance Universe") selected by Lipper over the one-, three-, five-, and ten-year and since

31

UBS PACE Money Market Investments

Board approval of investment management and administration agreement during the period February 1, 2007 through July 31, 2007 (unaudited)

inception periods ended April 30, 2007 and (b) annualized performance information for each year in the ten-year (or shorter) period ended April 30, 2007. The board was provided with a description of the methodology Lipper used to determine the similarity of a Portfolio with the funds included in its Performance Universe. The board also noted that it had received information throughout the year at periodic intervals with respect to the Portfolio's performance. The comparative Lipper information showed that the Portfolio's performance was in the second quintile for the one-, three-, five- and ten-year periods and since inception (with the first quintile representing that fifth of the funds in the Performance Universe with the best relative performance). Based on its review, the board concluded that the Portfolio's investment performance was satisfactory.

Adviser profitability—The board received and considered a profitability analysis of UBS Global AM and its affiliates in providing services to the Portfolio. The board also received profitability information with respect to the UBS New York fund complex as a whole. In addition, the board received information with respect to UBS Global AM's allocation methodologies used in preparing this profitability data, as noted above. UBS Global AM's profitability was considered not excessive in light of the nature, extent and quality of the services provided to the Portfolio.

Economies of scale—The board received and considered information from management regarding whether UBS Global AM realizes economies of scale as the Portfolio's assets grew beyond current levels, whether the Portfolio has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale for the Portfolio. The board considered whether economies of scale in the provision of services to the Portfolio were being passed along to the shareholders. The board noted that the Portfolio's Contractual Management Fee did not contain breakpoints. The board considered that to the extent the Portfolio's assets have increased over time, however, it has realized other economies

32

UBS PACE Money Market Investments

Board approval of investment management and administration agreement during the period February 1, 2007 through July 31, 2007 (unaudited)

of scale as certain expenses, such as fees for Trustees, auditor and legal fees and printing and postage, become a smaller percentage of overall assets. Generally, the board believed that UBS Global AM's sharing of economies of scale with the Portfolio was acceptable

Other benefits to UBS Global AM—The board considered other benefits received by UBS Global AM and its affiliates as a result of its relationship with the Portfolio, including the opportunity to offer additional products and services to Portfolio shareholders. In light of the costs of providing investment management, administrative and other services to the Portfolio and UBS Global AM's ongoing commitment to the Portfolio, the profits and other ancillary benefits that UBS Global AM and its affiliates received were considered reasonable.

In light of all of the foregoing, the board approved the Investment Management and Administration Agreement for the Portfolio.

No single factor reviewed by the board was identified by the board as the principal factor in determining whether to approve the Investment Management and Administration Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process. The board discussed the proposed continuance of the Investment Management and Administration Agreement in a private session with their independent legal counsel at which no representatives of UBS Global AM were present.

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 services(1) 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.

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.
