                               OCTOBER 31, 1997
<PAGE>
 
Dear Shareholders:
 
The IRC Enhanced Index Portfolio (the "Portfolio") managed by Investment
Research Company ("IRC") returned 12.46% for the six-month period ended
October 31, 1997 relative to a return of 15.16% for the S&P 500 Index.
Beginning in May, the previously persistent dominance of large cap growth
stocks in the market was broken, with the S&P MidCap 400 out-performing the
S&P 500 by 2.65%. This reversal of relative fortunes for the mid-cap sector of
the market continued beyond May, with the S&P MidCap 400 rising 24.1% for the
six months ended October 31, 1997, beating the S&P 500 by nearly 9%. There was
a similar reversal of the dominance of growth stocks during this period, with
the S&P/BARRA Growth index rising 14.3% relative to the stronger 16.0%
increase in the S&P/BARRA Value index.
 
While the Portfolio reflects the weighted average capitalization and industry
composition of the S&P 500 Index benchmark, its median market capitalization
level is higher than that of the S&P 500, primarily as a result of the lower
level of assets under management. IRC's investment strategy favors companies
with higher dividends and lower price/earnings; i.e., there is a value bias to
the stock selection. While benefiting over this period from its value
orientation, the Portfolio's relative underperformance can be attributed to
the relatively greater significance of the performance-lagging larger cap
holdings in the Portfolio's composition and to the under-representation in the
better performing relatively smaller cap issues within the S&P 500. IRC
continues to invest in companies with solid fundamentals and relatively low
volatility which we believe represent the best opportunity for long term value
added.
 
OVERVIEW OF ECONOMIC AND MARKET CONDITIONS
 
The market during the first half of the six-month period ended October 31,
1997 accelerated along its growth path, with the S&P 500 rising 19.7%. The
unexpected continued strength of the economy and corporate profits contributed
greatly as did the Federal Reserve Board's decision not to stand in the
market's way, given that signs of growth-inspired inflation were mixed at
best. And investor concerns that the Fed might engage in a series of
preemptive interest rate hikes this year moderated, as evidenced by the
resumed influx of money into investment portfolios. The second half of this
period, however, saw the market sell off, as the S&P 500 fell 3.8%. While the
continued forbearance by the Fed and positive company earnings reports served
as a strong base for the market, concerns over high valuations and doubts
about the continued longevity of high corporate earnings contributed to a 5.6%
drop in the S&P 500 in August. The market recovered substantially in
September, as many investors were again encouraged by the concurrence of low
inflation, good corporate earnings reports, steady economic growth and a
Federal Reserve willing to leave well enough alone. However, the S&P 500
dropped 3.3% in October in reaction to falling international markets and
renewed nervousness about future corporate earnings.
 
INVESTMENT STRATEGIES AND TECHNIQUES APPLIED BY IRC DURING THE PERIOD
 
IRC's entire investment process is based on proprietary research and years of
hands on portfolio management by the firm's investment committee. Our approach
to valuation and portfolio management centers around diversified positions in
stable, fundamentally attractive securities. Since IRC makes no forecasts of
market or economic sector returns, market and sector timing are not used.
Portfolios are kept as fully invested as practicable and the economic sector
weights of all portfolios closely reflect the weights of the benchmark index.
While IRC's value added is independent of market direction, our performance
will be strongest when investors link securities' prices to underlying
fundamentals.
 
VALUATION
 
IRC adds value through systematically constructed positions in companies that
are fundamentally attractive on a risk-adjusted basis. Companies must pass
sector specific filters for earnings and dividends. All candidate
 
                                       1
<PAGE>
 
securities must then pass through a volatility/momentum screen where the
capitalization weighted geometric return to the fundamentally attractive
stocks is maximized. This volatility/momentum screen ensures that we are
identifying companies with a stable or improving price pattern, eliminating
"value traps" which are companies that might appear to be fundamentally
attractive because their prices are falling faster than their earnings or
dividends.
 
Research performed at IRC in 1996 led to some modifications in our valuation
process. Originally, our valuation screens were applied uniformly across all
segments of the market. Based on observations of varying treatment of earnings
and dividends across various market sectors, filters were adjusted to reflect
market preferences in some sectors. For example, companies in the electronics
sector are no longer excluded as buy candidates if their dividend payout is
below average. However, these firms must have a P/E ratio which is below
average for electronics firms.
 
PORTFOLIO MANAGEMENT
 
All acceptable candidates across economic sectors form the new investable
universe used in the portfolio rebalance. This rebalance typically occurs on a
90 day cycle and the oldest one-third of each client's portfolio is re-
examined. This process, which is known as time diversification, helps us to
focus our buy and sell decisions on longer term fundamental attractiveness. By
segregating the holdings we minimize noise transactions caused by short term
price behavior, a prevalent problem which adversely affects quantitative
portfolio managers. Finally, IRC evaluates the aggregate portfolio to ensure
that it offers appropriate market capitalization, tracking error, and other
supplemental factors. Trading is performed on a best execution basis. We make
extensive use of electronic crossing networks and typically maintain a per
share trade cost below 2.5 cents per share.
 
CURRENT OUTLOOK
 
IRC does not attempt to overlay its quantitative stock selection models with
any type of predicted economic outlook. However, due to very high stock prices
relative to historical measures of value, IRC's models have positioned the
Portfolio with a distinct value bias. An integral component of IRC's strategy
is to control the risk of significant under-performance in the event of a
market downturn.
 
INVESTMENT RESEARCH COMPANY
 
                      DEFINITION OF THE COMPARATIVE INDEX
                      -----------------------------------

The S&P 500 Index is an unmanaged index composed of 400 industrial, 40
financial, 40 utilities and 20 transportation stocks.
 
Comparisons of performance assume reinvestment of dividends.
 
The investment results presented in the Adviser's letter represent past
performance and should not be construed as a guarantee of future results. If
the Adviser did not have temporary fee waivers and did not assume expenses on
behalf of the Portfolio, total return for the Portfolio would have been lower.
The investment 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.
 
Please note that one cannot invest in an unmanaged index.

                         IRC ENHANCED INDEX PORTFOLIO
 
                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
UAM Funds Trust and UAM Funds, Inc. (collectively the "UAM Funds") are
registered under the Investment Company Act of 1940, as amended. The IRC
Enhanced Index Portfolio (the "Portfolio"), a portfolio of UAM Funds Trust, is
a diversified, open-end management investment company. At October 31, 1997,
the UAM Funds were comprised of forty-two active portfolios. The financial
statements of the remaining portfolios are presented separately. The objective
of the IRC Enhanced Index Portfolio is to provide a total return exceeding
that of the S&P 500 Index.
 
A. SIGNIFICANT ACCOUNTING POLICIES: The following significant accounting
policies are in conformity with generally accepted accounting principles. Such
policies are consistently followed by the Portfolio in the preparation of its
financial statements. Generally accepted accounting principles may require
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results may differ from
those estimates.
 
  1. SECURITY VALUATION: Securities listed on a securities exchange for which
  market quotations are readily available are valued at the last quoted sales
  price as of the close of the exchange on the day the valuation is made or,
  if no sale occurred on such day, at the bid price on such day. Price
  information on listed securities is taken from the exchange where the
  security is primarily traded. Over-the-counter and unlisted securities are
  valued at the current bid price. Short-term investments that have remaining
  maturities of sixty days or less at time of purchase are valued at
  amortized cost, if it approximates market value. The value of other assets
  and securities for which no quotations are readily available is determined
  in good faith at fair value using methods determined by the Board of
  Trustees.
 
  2. FEDERAL INCOME TAXES: It is the Portfolio's intention to qualify as a
  regulated investment company under Subchapter M of the Internal Revenue
  Code and to distribute all of its taxable income. Accordingly, no provision
  for Federal income taxes is required in the financial statements.
 
  3. DISTRIBUTIONS TO SHAREHOLDERS: The Portfolio will normally distribute
  substantially all of its net investment income quarterly. Any realized net
  capital gains will be distributed annually. All distributions are recorded
  on ex-dividend date.
 
  The amount and character of income and capital gain distributions to be
  paid are determined in accordance with Federal income tax regulations which
  may differ from generally accepted accounting principles.
 
  Permanent book-tax differences, if any, are not included in ending
  undistributed net investment income (loss) for the purpose of calculating
  net investment income (loss) per share in the financial highlights.
 
  4. OTHER: Security transactions are accounted for on trade date, the date
  the trade was executed. Costs used in determining realized gains and losses
  on the sale of investment securities are based on the specific
  identification method. Dividend income is recorded on the ex-dividend date.
  Most expenses of the UAM Funds can be directly attributed to a particular
  portfolio. Expenses which cannot be directly attributed are apportioned
  among the portfolios of the UAM Funds based on their relative net assets.
  Custodian fees for the Portfolio have been increased to include expense
  offsets, if any, for custodian balance credits.
 
B. ADVISORY SERVICES: Under the terms of an investment advisory agreement,
Investment Research Company (the "Adviser"), a wholly-owned subsidiary of
United Asset Management Corporation ("UAM"), provides investment advisory
services to the Portfolio at a monthly fee calculated at an annual rate of
0.70% of average
 
                                      12

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)

daily net assets for the month. The Adviser has voluntarily agreed to waive a
portion of its advisory fees and to assume expenses, if necessary, in order to
keep the Portfolio's total annual operating expenses, after the effect of
expense offset arrangements, from exceeding 2.50% of average daily net assets.
 
C. ADMINISTRATION SERVICES: UAM Fund Services, Inc. (the "Administrator"), a
wholly-owned subsidiary of UAM, provides and oversees administrative, fund
accounting, dividend disbursing and transfer agent services to the UAM Funds
under a Fund Administration Agreement (the "Agreement"). Pursuant to the
Agreement, the Administrator is entitled to receive annual fees, computed
daily and payable monthly, of 0.19% of the first $200 million of the combined
aggregate net assets; plus 0.11% of the next $800 million of the combined
aggregate net assets; plus 0.07% of the next $2 billion of the combined
aggregate net assets; plus 0.05% of the combined aggregate net assets in
excess of $3 billion. The fees are allocated among the portfolios of the UAM
Funds on the basis of their relative net assets and are subject to a graduated
minimum fee schedule per portfolio which rises from $2,000 per month, upon
inception of a portfolio, to $70,000 annually after two years. For portfolios
with more than one class of shares, the minimum annual fee increases to
$90,000. In addition, the Administrator receives a Portfolio-specific monthly
fee at an annual rate of 0.04% of average daily net assets of the Portfolio.
The Administrator has entered into a Mutual Funds Service Agreement with Chase
Global Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan
Bank, under which CGFSC agrees to provide certain services, including but not
limited to, administration, fund accounting, dividend disbursing and transfer
agent services. Pursuant to the Mutual Funds Service Agreement, the
Administrator pays CGFSC a monthly fee. For the six months ended October 31,
1997, $36,995 was paid to CGFSC for its services.
 
D. CUSTODIAN: The Chase Manhattan Bank ("the Bank"), an affiliate of CGFSC, is
custodian for the Portfolio's assets held in accordance with the custodian
agreement.
 
E. DISTRIBUTION SERVICES: UAM Fund Distributors, Inc. (the "Distributor"), a
wholly-owned subsidiary of UAM, distributes the shares of the Portfolio. The
Distributor does not receive any fee or other compensation with respect to the
Portfolio.
 
F. ACCOUNT SERVICES: The UAM Funds entered into an Account Services Agreement
(the "Services Agreement") with UAM Retirement Plan Services, Inc. ("Service
Provider"), a wholly-owned subsidiary of UAM. Under the Services Agreement,
the Service Provider agrees to perform certain services for participants in a
self-directed, defined contribution plan, and for whom the Service Provider
provides participant recordkeeping. Pursuant to the Services Agreement, the
Service Provider is entitled to receive, after the end of each month, a fee at
the annual rate of 0.15% of the average aggregate daily net asset value of
shares of the UAM Funds in the accounts for which they provide services.
 
G. TRUSTEES' FEES: Each Trustee, who is not an officer or affiliated person,
receives $2,000 per meeting attended, which is allocated proportionally among
the active portfolios of UAM Funds, plus a quarterly retainer of $150 for each
active portfolio of the UAM Funds, and reimbursement of expenses incurred in
attending Trustee meetings.

<PAGE>
 
Dear Shareholders:
 
The current fiscal year began May 1st with the long Treasury bond at 6.95% and
the market concerned about the next Federal Reserve move following the March
25th 25 basis point increase in the Fed Funds rate to 5.5%. Evidence of a
slower economy and surprisingly low inflation reports gradually changed market
sentiment and rates began to decline. Rates moved lower through the end of
July with the long Treasury bond at 6.27%. The market was jolted by a very
strong employment report at the first of August and rates moved back up to
6.68%.
 
Gradually the market sentiment turned positive again as low inflation
statistics continued to be impressive. We end October with the lowest
unemployment and inflation in three decades. The Federal Government has a
chance to run a balanced budget in fiscal 1998 and our currency proves its
worth as all market participants watch the Asian currency turmoil. Rates end
October with the long Treasury bond at 6.15%, but shorter term rates have
declined less as the Federal Reserve remains on inflation watch until the
economy slows. The following table reviews Treasury rates from short term to
the long bond.

The consensus economic outlook appears to be changing with growth rates being
revised down due to "Asian Flu," although concerns remain about a gradual
uptick in wage/inflation pressures. Long rates have declined in reaction to
slower growth forecasts, foreign money flows into the U.S. dollar, and even
asset allocation flows out of stocks into bonds. Shorter term rates are
hostage to the Federal Reserve's actions which are on hold at the moment.
 
This market environment of sharply declining rates will not favor our
investment style although absolute bond returns have improved. We are a
"bottom-up value manager" focused not on market timing but on security and
sector selection. This process seeks to produce a yield in the portfolio
higher than the market benchmark with returns that are less volatile. Our
focus on the so-called "spread sectors"--investment grade corporates,
mortgages, and asset-backed securities offers higher return potential, but the
recent market volatility has caused Treasury bonds to outperform over the past
month. We continue to believe that yield over time, not market timing, creates
wealth. At October 31, 1997, the 30 day SEC yield for the Institutional Class
Shares was 6.12% and the 30 day SEC yield for the Institutional Service Class
Shares was 5.87%.

BHM&S TOTAL RETURN BOND PORTFOLIO INVESTMENT STRATEGIES
 
 . CORPORATES: While yield spreads of investment grade corporate issues versus
  Treasuries have widened, the solid credit fundamentals which support
  outperformance of the sector persist. Favorable economic conditions of
  growth with modest inflation have supported corporate earnings. The dollar
  value of upgrades continues at twice the pace of downgrades. Over the fiscal
  year to date the following names have been upgraded or watch listed for
  upgrade: Southern California Edison A2 to A1 (6/13/97); Halliburton A2/A
  watch up (6/11/97); NationsBank A1/A watch up. U.S. West was placed on
  watchlist with negative implications due to corporate restructuring of its
  cable business; however, a positive development has been Microsoft's new
  investment position and expressed interest in the U.S. West cable
  operations. Our selection decisions continue to focus on companies we
  believe offer the strongest prospects for material credit improvement.
 
 . MORTGAGES: Interest rate volatility rekindled investor fear of prepayments
  causing mortgages to underperform comparable duration Treasuries. The
  psychologically important 6% yield level on the ten-year Treasury created
  minor selling pressures and wider spreads. The prospects of a resurgence in
  refinancing activity could further add to spread risk, though seasonal
  factors favor a slowing in the pace of housing activity. We have been
  underweighted in the sector, but are considering the current higher than
  average yield spreads attractive. We will be a buyer of this sector if yield
  spreads move out to their widest levels of the past 12 months.
 
 . ASSET-BACKED SECURITIES: Record new issue supply and other technical
  conditions created marginal spread widening in this sector. Over the
  trailing 12 months this sector has outperformed similar duration Treasuries.
  Investor attention is now squarely centered on the anticipation of a new
  class of asset-backed securities resulting from the electric utility
  industry's "stranded asset" securitization. New legislative action is
 
                                       2
<PAGE>
 
  establishing a statutory framework for utilities to issue an estimated $50
  billion in bonds backed by "transition charges" which will enable the
  companies to more rapidly recover their investments in expensive nuclear
  plants.
 
 . TREASURY YIELD CURVE: Our strategy continues to favor those issues with the
  most attractive "roll-down" maturity which concentrate in 2000-01, 2004-05,
  and 2015-19. The yield curve has flattened by 14 basis points as measured by
  the two-thirty year differential of +54 basis points. If this flattening of
  the yield curve continues, it will favor a more bulleted maturity structure
  concentrating in 7-9 year maturities.
 
INVESTMENT PERFORMANCE
 
The Portfolio has two separate classes of shares, Institutional Class Shares
("Institutional Shares") and Institutional Service Class Shares ("Service
Shares"). For the six months ended October 31, 1997, the absolute performance
has improved for both classes of shares since the April 1997 Annual Report.
The total return, encompassing both price change and income, for the
INSTITUTIONAL SHARES WAS 6.50% and the total return for the SERVICE SHARES WAS
6.40%, compared to the Lehman Aggregate Bond Index return of 7.07%.
 
Since inception on November 1, 1995 through October 31, 1997 the INSTITUTIONAL
SHARES ANNUALIZED TOTAL RETURN IS 6.66% and the annualized total return of the
SERVICE SHARES IS 6.39%, compared to the Lehman Aggregate Bond Index return of
7.23%. The shortfall in performance for both classes of shares compared to the
market index is largely explained by fund expenses that are not included in
the market index's return.
 
We continue to work on improving the prospects for this mutual fund. Assets
have grown from $17.1 million to $31.4 million since April. The NASDAQ ticker
symbol for the Institutional Shares is BHMSX and for the Service Shares the
ticker is BHYYX. We hope this review answers your questions regarding the
portfolio's management.

                      DEFINITION OF THE COMPARATIVE INDEX
                      -----------------------------------
 
Lehman Brothers Aggregate Bond Index--is a fixed income market value-weighted
index that combines the Lehman Brothers Government Corporate Bond Index and
the Lehman Brothers Mortgage-Backed Securities Index. It includes fixed rate
issues of investment grade (BBB) or higher, with maturities of at least one
year and outstanding par values of at least $100 million for U.S. Government
issues and $25 million for others.
 
Comparisons of performance assume reinvestment of dividends.
 
The investment results presented in the Adviser's letter represent past
performance and should not be construed as a guarantee of future results. If
the Adviser didn't have temporary fee waivers and didn't assume expenses on
behalf of the Portfolio, total return for the Portfolio would have been lower.
The investment 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.
 
Please note that one cannot invest in an unmanaged index.

                       BHM&S TOTAL RETURN BOND PORTFOLIO
 
                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

UAM Funds Trust and UAM Funds, Inc. (collectively the "UAM Funds") are
registered under the Investment Company Act of 1940, as amended. The BHM&S
Total Return Bond Portfolio (the "Portfolio"), a portfolio of UAM Funds Trust,
is a diversified, open-end management investment company. At October 31, 1997,
the UAM Funds were comprised of forty-two active portfolios. The financial
statements of the remaining portfolios are presented separately. The Portfolio
is authorized to offer two separate classes of shares--Institutional Class
Shares and Institutional Service Class Shares. Both classes of shares have
identical voting rights (except Institutional Service Class shareholders have
exclusive voting rights with respect to matters relating to distribution and
shareholder servicing of such shares), dividend, liquidation and other rights.
The objective of the BHM&S Total Return Bond Portfolio is to provide a maximum
long term total return consistent with reasonable risk to principal by
investing in investment grade fixed income securities of varying maturities.
 
A. SIGNIFICANT ACCOUNTING POLICIES: The following significant accounting
policies are in conformity with generally accepted accounting principles. Such
policies are consistently followed by the Portfolio in the preparation of its
financial statements. Generally accepted accounting principles may require
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results may differ from
those estimates.
 
  1. SECURITY VALUATION: Fixed income securities are stated on the basis of
  valuations provided by brokers and/or a pricing service which uses
  information with respect to transactions in fixed income securities,
  quotations from dealers, market transactions in comparable securities and
  various relationships between securities in determining value. Short-term
  investments that have remaining maturities of sixty days or less at time of
  purchase are valued at amortized cost, if it approximates market value. The
  value of other assets and securities for which no quotations are readily
  available is determined in good faith at fair value using methods
  determined by the Board of Trustees.
 
  2. FEDERAL INCOME TAXES: It is the Portfolio's intention to qualify as a
  regulated investment company under Subchapter M of the Internal Revenue
  Code and to distribute all of its taxable income. Accordingly, no provision
  for Federal income taxes is required in the financial statements.
 
  At April 30, 1997, the Portfolio had available a capital loss carryover for
  federal income tax purposes of $34,317 which will expire on April 30, 2005.
 
  3. REPURCHASE AGREEMENTS: In connection with transactions involving
  repurchase agreements, the Portfolio's custodian bank takes possession of
  the underlying securities, the value of which exceeds the principal amount
  of the repurchase transaction, including accrued interest. To the extent
  that any repurchase transaction exceeds one business day, the value of the
  collateral is monitored on a daily basis to determine the adequacy of the
  collateral. In the event of default on the obligation to repurchase, the
  Portfolio has the right to liquidate the collateral and apply the proceeds
  in satisfaction of the obligation. In the event of default or bankruptcy by
  the other party to the agreement, realization and/or retention of the
  collateral or proceeds may be subject to legal proceedings.
 
  Pursuant to an Exemptive Order issued by the Securities and Exchange
  Commission, the UAM Funds may transfer their daily uninvested cash balances
  into a joint trading account which invests in one or more repurchase
  agreements. This joint repurchase agreement is covered by the same
  collateral requirements as discussed above.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)

  4. DISTRIBUTIONS TO SHAREHOLDERS: The Portfolio will normally distribute
  substantially all of its net investment income quarterly. Any realized net
  capital gains will be distributed annually. All distributions are recorded
  on ex-dividend date.
 
  The amount and character of income and capital gain distributions to be
  paid are determined in accordance with Federal income tax regulations which
  may differ from generally accepted accounting principles. These differences
  are primarily due to differing book and tax treatments for paydown gains
  (losses), post-October capital losses and the timing of the recognition of
  gains or losses on investments.
 
  Permanent book-tax differences, if any, are not included in ending
  undistributed net investment income (loss) for the purpose of calculating
  net investment income (loss) per share in the financial highlights.
 
  5. OTHER: Security transactions are accounted for on trade date, the date
  the trade was executed. Costs used in determining realized gains and losses
  on the sale of investment securities are based on the specific
  identification method. Interest income is recognized on the accrual basis.
  Discounts and premiums on securities purchased are amortized using the
  effective yield basis over their respective lives. Most expenses of the UAM
  Funds can be directly attributed to a particular portfolio. Expenses which
  cannot be directly attributed are apportioned among the portfolios of the
  UAM Funds based on their relative net assets. Income, expenses (other than
  class specific expenses) and realized and unrealized gains or losses are
  allocated to each class of shares based upon their relative net assets.
  Custodian fees for the Portfolio have been increased to include expense
  offsets, if any, for custodian balance credits.
 
B. ADVISORY SERVICES: Under the terms of an investment advisory agreement,
Barrow, Hanley, Mewhinney, & Strauss, Inc. (the "Adviser"), a wholly-owned
subsidiary of United Asset Management Corporation ("UAM"), provides investment
advisory services to the Portfolio at a monthly fee calculated at an annual
rate of 0.35% of average daily net assets for the month. Through December
31,1997, the Adviser has voluntarily agreed to waive a portion of its advisory
fees and to assume expenses, if necessary, in order to keep the Portfolio's
total annual operating expenses, after the effect of expense offset
arrangements, from exceeding 0.55% and 0.80% of average daily net assets of
the Portfolios' Institutional Class Shares and Service Class Shares,
respectively.
 
C. ADMINISTRATION SERVICES: UAM Fund Services, Inc. (the "Administrator"), a
wholly-owned subsidiary of UAM, provides and oversees administrative, fund
accounting, dividend disbursing and transfer agent services to the UAM Funds
under a Fund Administration Agreement (the "Agreement"). Pursuant to the
Agreement, the Administrator is entitled to receive annual fees, computed
daily and payable monthly, of 0.19% of the first $200 million of the combined
aggregate net assets; plus 0.11% of the next $800 million of the combined
aggregate net assets; plus 0.07% of the next $2 billion of the combined
aggregate net assets; plus 0.05% of the combined aggregate net assets in
excess of $3 billion. The fees are allocated among the portfolios of the UAM
Funds on the basis of their relative net assets and are subject to a graduated
minimum fee schedule per portfolio which rises from $2,000 per month, upon
inception of a portfolio, to $70,000 annually after two years. For portfolios
with more than one class of shares, the minimum annual fee increases to
$90,000. In addition, the Administrator receives a Portfolio-specific monthly
fee at an annual rate of 0.04% of average daily net assets of the Portfolio.
The Administrator has entered into a Mutual Funds Service Agreement with Chase
Global Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan
Bank, under which CGFSC agrees to provide certain services, including but not
limited to, administration, fund accounting, dividend disbursing and transfer
agent

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)

services. Pursuant to the Mutual Funds Service Agreement, the Administrator
pays CGFSC a monthly fee. For the six months ended October 31, 1997, $47,446
was paid to CGFSC for its services.
 
D. CUSTODIAN: The Chase Manhattan Bank (the "Bank"), an affiliate of CGFSC, is
custodian for the Portfolio's assets held in accordance with the custodian
agreement.
 
E. DISTRIBUTION SERVICES: UAM Fund Distributors, Inc. (the "Distributor), a
wholly-owned subsidiary of UAM, distributes the shares of the Portfolio. The
Portfolio has adopted Distribution and Service Plans (the "Plans") on behalf
of the Service Class Shares pursuant to Rule 12b-1 under the Investment
Company Act of 1940. Under the Plans, the Portfolio may not incur distribution
and service fees which exceed an annual rate of 0.75% of the Portfolio's net
assets, however, the Board has currently limited aggregate payments under the
Plans to 0.50% per annum of the Portfolio's net assets. The Portfolio's
Service Class Shares are not currently making payments for distribution fees,
however the Portfolio does pay service fees at an annual rate of 0.25% of the
average daily value of Service Class Shares owned by clients of the Service
Agents.
 
F. ACCOUNT SERVICES: The UAM Funds entered into an Account Services Agreement
(the "Services Agreement") with UAM Retirement Plan Services, Inc. ("Service
Provider"), a wholly-owned subsidiary of UAM. Under the Services Agreement,
the Service Provider agrees to perform certain services for participants in a
self-directed, defined contribution plan, and for whom the Service Provider
provides participant recordkeeping. Pursuant to the Services Agreement, the
Service Provider is entitled to receive, after the end of each month, a fee at
the annual rate of 0.15% of the average aggregate daily net asset value of
shares of the UAM Funds in the accounts for which they provide services.
 
G. TRUSTEES' FEES: Each Trustee, who is not an officer or affiliated person,
receives $2,000 per meeting attended, which is allocated proportionally among
the active portfolios of UAM Funds, plus a quarterly retainer of $150 for each
active portfolio of the UAM Funds and reimbursement of expenses incurred in
attending Trustee meetings.
 
H. PURCHASES AND SALES: For the six months ended October 31, 1997, the
Portfolio made purchases of $11,766,775 and sales of $3,160,131 of investment
securities other than long-term U.S. Government and short-term securities.
Purchases and sales of long-term U.S. Government securities total $15,589,100
and $11,703,735, respectively.
 
I. LINE OF CREDIT: The Portfolio, along with certain other Portfolios of UAM
Funds, collectively entered into an agreement which enables them to
participate in a $100 million unsecured line of credit with several banks.
Borrowings will be made solely to temporarily finance the repurchase of
Capital shares. Interest is charged to each participating Portfolio based on
its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%.
In addition, a commitment fee of 0.08% per annum, payable at the end of each
calendar quarter, is accrued by each participating Portfolio based on its
average daily unused portion of the line of credit. During the six months
ended October 31, 1997, the Portfolio had no borrowings under the agreement.
 
J. OTHER: At October 31, 1997, 81.1% and 58.4% of total shares outstanding
were held by 4 and 3 record shareholders of the Institutional Class Shares and
the Institutional Service Class Shares, respectively, owning more than 10% of
the aggregate total shares outstanding.

<PAGE>
 
DEAR SHAREHOLDER,
 
MJI INTERNATIONAL EQUITY PORTFOLIO, SIX MONTHS ENDED OCTOBER 31, 1997
 
PERFORMANCE
 
During the six months ended October 31, 1997, the return for the Portfolio was
3.38% compared with 3.15% for the MSCI EAFE Index. For the same time period,
the Portfolio's Institutional Service Class Shares returned 3.19%. The period
was characterized by the stark difference between returns of markets in Asia,
which were dragged down by weak fundamentals and declining currencies, and the
relative resilience of markets in Europe which still enjoyed moderate growth.
Late in the period, however, all markets were impacted by events.
 
ECONOMIC AND MARKET REVIEW
 
The collapse in Asia began in Thailand and led to a domino effect on the
markets and currencies of neighboring countries. Malaysia, Indonesia and the
Philippines were worst hit but Singapore also came under pressure. Meanwhile,
the Japanese economy, which had shown some life early in the year, experienced
a weak second quarter. The European markets welcomed the stable interest rate
background and made steady progress. However, as intervention by the
International Monetary Fund (IMF) in Thailand and later in Malaysia and
Indonesia began to stabilize the situation, confidence began to return to the
region.
 
The European markets returned 12.3% for the period. Strong early in the year,
Germany's gloss began to fade when several large cash raising issues were
announced. In France, restructuring was seen as positive for the market. The
steady improvement in inflation in Italy, which allowed the government to
continue to reduce interest rates, led to a surge in the market of 20.3%. The
UK also saw a steady market on the back of slowing retail sales and moderate
inflationary pressure. Late in September, press reports that the government
would take part in the single European currency were welcomed, leading to a
surge in equities. The government has made moves to join the single currency
although the date of entry has yet to be confirmed. Assuming the rate at which
the pound goes in is appropriate, this will be a sound policy, given the high
percentage of trade which the UK conducts with Europe. The late move in UK
equity prices led to a return on the market of 14.0% for the period.
 
Figures released during the period made it clear that the Japanese economy had
faltered through the middle of the year. On top of this a setback to trade
with Southeast Asia, which constitutes a high proportion of Japan's overall
trade, can only make matters worse. Results from the September half year
should begin to give some impression of the depth of the problems but the
impact will be felt for some months to come. Clearly, with a weak domestic
economy the government has few options other than deregulation (streamlining
the bureaucracy and reducing the costs associated with red tape) and allowing
the currency to drift lower. Against a poor economic background, the Japanese
market ended the period down 5.5%.
 
The Southeast Asian governments have begun to address their problems and reach
agreements with the IMF. The problems of the region stem from over-development
in the early 1990's, a time of heavy capital flows into the region. This led
to the over-supply of property and infrastructure which could not cope.
Political leadership and control of the banking systems have also been shown
to be weak. The key to recovery will be the speed with which governments allow
the markets to correct imbalances in property prices and resist the temptation
to support poor quality financial institutions. The region will not escape
deflationary pressures over the coming months but a positive approach to the
issues will avoid the long road to recovery seen in Japan. Australia and
 
                                       1
<PAGE>
 
New Zealand, which supply much of the raw materials for industry in Asia will
also be caught in the slowdown but the lower interest rate environment will
continue to support financial stocks in those markets.
 
The Latin American markets demonstrated their resilience in the face of the
problems in Asia early in the period but ultimately suffered when investors
sought to realize profits to offset losses in Asia. Chile ended the period
down 3.6%; Argentina fell 12.6% but Mexico, where earnings continued to exceed
expectations, saw the market up 12.6%.
 
INVESTMENT STRATEGY
 
Early in 1997 the Portfolio had been heavily overweight in the Asian markets,
but as the situation in the region deteriorated we reduced exposure, selling
all remaining holdings in Malaysia in early August. Since those sales were
completed the market fell a further 44.5% in dollars. The Portfolio was not
invested in Thailand, the Philippines or Indonesia. Investments in Singapore
were reduced but since this market still has the strongest economic
fundamentals of the region, we remain overweight versus the small percentage
which Singapore represents in the benchmark. Exposure to Australia was also
reduced. Holdings which remain in Australia are financial stocks which will be
beneficiaries of the easier interest rate background which we expect to see in
the country as economic activity slows.
 
The focus of the Portfolio has continued to be on the European markets,
however, within Europe we shifted the emphasis from Germany, taking profits in
Volkswagen, to Italy and France. Italy has been double weighted in the
portfolio compared with the index as the government's success in reducing
inflation and interest rates in addition to the restructuring program in
industry encouraged the market to be the best in Europe during the quarter.
The reductions to Germany and the Netherlands were also correct decisions
since those markets have begun to underperform Europe as a whole.
 
As the new government becomes established in the UK it is creating a
commendable record, helped by the moderating of the pace of the economy and
the beginnings of the shift towards integration of the pound with the single
European currency. While the Portfolio was underweight in the UK, these
policies should set the stage for a sound market over the next few months. We
have therefore begun to increase exposure and broaden investments to include
manufacturers and exporters which will benefit if the pound begins to ease
back in this process.
 
While we were becoming more optimistic on the prospects for Japan and had
begun to raise exposure to the market, the dramatic weakening of the economy
in the middle of the year and the expectations of a slow second half as a
result of the weakness in Southeast Asia have led us to put any further
investments on hold. While underweight in the market during the period, stock
selection has outperformed the market overall.
 
MARKET OUTLOOK
 
During the third quarter, investors' nerves were tested when the crisis in
markets in the Far East impacted all world markets. Interestingly, those
markets with strong fundamentals rebounded in September but volatility was a
feature of the period and this looks set to continue for some time.
 
In the coming months we see the two tier structure continuing: markets in the
Far East will remain weak until it is clear that measures to strengthen
economies and currencies are in place. Conversely, the European markets which
reflect stronger economies are enjoying progress which we expect to continue.
Developments which could
 
                                       2
<PAGE>
 
potentially upset this scenario are twofold: either earnings will disappoint,
leaving current stock prices at too high a level, or the interest rate cycle
will turn, probably with the Fed and the Bundesbank making the first moves.
This will also emphasize the high prices currently being paid for stock and
could lead to a correction. We believe that while inflation in Germany has
been rising, albeit from very low levels, unemployment is also growing and
moves to raise rates will only make the employment situation worse. Although
the US economy continues to grow at a steady pace, we have seen no evidence of
inflation and if the Fed continues to focus on this statistic it will be able
to postpone any rise until late 1997 or early 1998. We will therefore continue
with the current investment stance: focus on Europe, and in particular, the
UK, maintaining an underweight exposure to South East Asia and a small
exposure to Latin America.

                      MJI INTERNATIONAL EQUITY PORTFOLIO
 
                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

UAM Funds Trust and UAM Funds, Inc. (collectively the "UAM Funds") are
registered under the Investment Company Act of 1940, as amended. The MJI
International Equity Portfolio (the "Portfolio"), a portfolio of UAM Funds
Trust, is a diversified, open-end management investment company. At October
31, 1997, the UAM Funds were comprised of forty-two active portfolios. The
financial statements of the remaining portfolios are presented separately. The
Portfolio is authorized to offer two separate classes of shares--Institutional
Class Shares and Institutional Service Class Shares. Both classes of shares
have identical voting rights (except Institutional Service Class shareholders
have exclusive voting rights with respect to matters relating to distribution
and shareholder servicing of such shares), dividend, liquidation and other
rights. The objective of the MJI International Equity Portfolio is to provide
maximum total return, including both capital appreciation and current income,
by investing primarily in the common stocks of companies based outside of the
United States.
 
A. SIGNIFICANT ACCOUNTING POLICIES: The following significant accounting
policies are in conformity with generally accepted accounting principles. Such
policies are consistently followed by the Portfolio in the preparation of its
financial statements. Generally accepted accounting principles may require
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results may differ from
those estimates.
 
  1. SECURITY VALUATION: Securities listed on a securities exchange for which
  market quotations are readily available are valued at the last quoted sales
  price as of the close of the exchange on the day the valuation is made or,
  if no sale occurred on such day, at the bid price on such day. Price
  information on listed securities is taken from the exchange where the
  security is primarily traded. Over-the-counter and unlisted securities are
  valued at the current bid price. Quotations of foreign securities and other
  assets in a foreign currency are converted to U.S. dollar equivalents. The
  converted value is based upon the bid price of the foreign currency against
  U.S. dollars quoted by any major bank or by a broker. Short-term
  investments that have remaining maturities of sixty days or less at time of
  purchase are valued at amortized cost, if it approximates market value. The
  value of other assets and securities for which no quotations are readily
  available is determined in good faith at fair value using methods
  determined by the Board of Trustees.
 
  2. FEDERAL INCOME TAXES: It is the Portfolio's intention to qualify as a
  regulated investment company under Subchapter M of the Internal Revenue
  Code and to distribute all of its taxable income. Accordingly, no provision
  for Federal income taxes is required in the financial statements.
 
  The Portfolio may be subject to taxes imposed by countries in which it
  invests. Such taxes are generally based on either income or gains earned or
  repatriated. The Portfolio accrues such taxes when the related income or
  gains are earned.
 
  At April 30, 1997, the Portfolio had available a capital loss carryover for
  Federal income tax purposes of approximately $45,000 which will expire on
  April 30, 2005.
 
  3. REPURCHASE AGREEMENTS: In connection with transactions involving
  repurchase agreements, the Portfolio's custodian bank takes possession of
  the underlying securities, the value of which exceeds the principal amount
  of the repurchase transaction, including accrued interest. To the extent
  that any repurchase transaction exceeds one business day, the value of the
  collateral is monitored on a daily basis to determine the adequacy of the
  collateral. In the event of default on the obligation to repurchase, the
  Portfolio has the right to liquidate the collateral and apply the proceeds
  in satisfaction of the obligation. In the event of default

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)
  or bankruptcy by the other party to the agreement, realization and/or
  retention of the collateral or proceeds may be subject to legal
  proceedings.
 
  Pursuant to an Exemptive Order issued by the Securities and Exchange
  Commission, the UAM Funds may transfer their daily uninvested cash balances
  into a joint trading account which invests in one or more repurchase
  agreements. This joint repurchase agreement is covered by the same
  collateral requirements as discussed above.
 
  4. FOREIGN CURRENCY TRANSLATION: The books and records of the Portfolio are
  maintained in U.S. dollars. Investment securities and other assets and
  liabilities denominated in a foreign currency are translated into U.S.
  dollars on the date of valuation. The Portfolio does not isolate that
  portion of realized or unrealized gains and losses resulting from changes
  in the foreign exchange rate from fluctuations arising from changes in the
  market prices of the securities. These gains and losses are included in net
  realized and unrealized gain and loss on investments on the statement of
  operations. Net realized and unrealized gains and losses on foreign
  currency transactions represent net foreign exchange gains or losses from
  forward foreign currency exchange contracts, disposition of foreign
  currencies, currency gains or losses realized between trade and settlement
  dates on securities transactions and the difference between the amount of
  the investment income and foreign withholding taxes recorded on the
  Portfolio's books and the U.S. dollar equivalent amounts actually received
  or paid.
 
  5. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS: The Portfolio may enter
  into forward foreign currency exchange contracts to protect the value of
  securities held and related receivables and payables against changes in
  future foreign exchange rates. A forward currency contract is an agreement
  between two parties to buy and sell currency at a set price on a future
  date. The market value of the contract will fluctuate with changes in
  currency exchange rates. The contract is marked-to-market daily using the
  current forward rate and the change in market value is recorded by the
  Portfolio as unrealized gain or loss. The Portfolio recognizes realized
  gain or loss when the contract is closed, equal to the difference between
  the value of the contract at the time it was opened and the value at the
  time it was closed. Risks may arise upon entering into these contracts from
  the potential inability of counterparties to meet the terms of their
  contracts and are generally limited to the amount of unrealized gain on the
  contracts, if any, at the date of default. Risks may also arise from the
  unanticipated movements in the value of a foreign currency relative to the
  U.S. dollar.
 
  6. DISTRIBUTIONS TO SHAREHOLDERS: The Portfolio will normally distribute
  substantially all of its net investment income annually. Any realized net
  capital gains will be distributed annually. All distributions are recorded
  on ex-dividend date.
 
  The amount and character of income and capital gain distributions to be
  paid are determined in accordance with Federal income tax regulations which
  may differ from generally accepted accounting principles. These differences
  are primarily due to differing book and tax treatments for foreign currency
  transactions, deferred organization costs and the timing of the recognition
  of gains or losses on investments.
 
  Permanent book-tax differences, if any, are not included in ending
  undistributed net investment income (loss) for the purpose of calculating
  net investment income (loss) per share in the financial highlights.
 
  7. ORGANIZATION COSTS: Costs incurred by the Portfolio in connection with
  its organization have been deferred and are being amortized on a straight-
  line basis over a five-year period.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)
 
  8. OTHER: Security transactions are accounted for on trade date, the date
  the trade was executed. Costs used in determining realized gains and losses
  on the sale of investment securities are based on the specific
  identification method. Dividend income is recorded on the ex-dividend date,
  except that certain dividends from foreign securities are recorded as soon
  as the Portfolio is informed of the ex-dividend date. Interest income is
  recognized on the accrual basis. Most expenses of the UAM Funds can be
  directly attributed to a particular portfolio. Expenses which cannot be
  directly attributed are apportioned among the portfolios of the UAM Funds
  based on their relative net assets. Income, expenses (other than class
  specific expenses) and realized and unrealized gains or losses are
  allocated to each class of shares based upon their relative net assets.
  Custodian fees for the Portfolio have been increased to include expense
  offsets, if any, for custodian balance credits.
 
B. ADVISORY SERVICES: Under the terms of an investment advisory agreement,
Murray Johnstone International Ltd., (the "Adviser"), a subsidiary of United
Asset Management Corporation ("UAM"), provides investment advisory services to
the Portfolio at a monthly fee calculated at an annual rate of 0.75% of
average daily net assets for the month. The Adviser has voluntarily agreed to
waive a portion of its advisory fees and to assume expenses, if necessary, in
order to keep the Portfolio's total annual operating expenses, after the
effect of expense offset arrangements, from exceeding 1.50% and 1.75% of
average daily net assets of the Portfolio's Institutional Class Shares and
Institutional Service Class Shares, respectively.
 
C. ADMINISTRATION SERVICES: UAM Fund Services, Inc. (the "Administrator"), a
wholly-owned subsidiary of UAM, provides and oversees administrative, fund
accounting, dividend disbursing and transfer agent services to the UAM Funds
under a Fund Administration Agreement (the "Agreement"). Pursuant to the
Agreement, the Administrator is entitled to receive annual fees, computed
daily and payable monthly, of 0.19% of the first $200 million of the combined
aggregate net assets; plus 0.11% of the next $800 million of the combined
aggregate net assets; plus 0.07% of the next $2 billion of the combined
aggregate net assets; plus 0.05% of the combined aggregate net assets in
excess of $3 billion. The fees are allocated among the portfolios of the UAM
Funds on the basis of their relative net assets and are subject to a graduated
minimum fee schedule per portfolio which rises from $2,000 per month, upon
inception of a portfolio, to $70,000 annually after two years. For portfolios
with more than one class of shares, the minimum annual fee increases to
$90,000. In addition, the Administrator receives a Portfolio-specific monthly
fee at an annual rate of 0.06% of average daily net assets of the Portfolio.
The Administrator has entered into a Mutual Funds Service Agreement with Chase
Global Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan
Bank, under which CGFSC agrees to provide certain services, including but not
limited to, administration, fund accounting, dividend disbursing and transfer
agent services. Pursuant to the Mutual Funds Service Agreement, the
Administrator pays CGFSC a monthly fee. For the six months ended October 31,
1997, $53,681 was paid to CGFSC for its services.
 
D. CUSTODIAN: The Chase Manhattan Bank, an affiliate of CGFSC, is custodian
for the Portfolio's assets held in accordance with the custodian agreement.
 
E. DISTRIBUTION SERVICES: UAM Fund Distributors, Inc. (the "Distributor"), a
wholly-owned subsidiary of UAM, distributes the shares of the Portfolio. The
Portfolio has adopted Distribution and Service Plans (the "Plans") on behalf
of the Service Class Shares pursuant to Rule 12b-1 under the Investment
Company Act of
 
                                      16
<PAGE>
 
                      MJI INTERNATIONAL EQUITY PORTFOLIO
 
            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)

1940. Under the Plans, the Portfolio may not incur distribution and service
fees which exceed an annual rate of 0.75% of the Portfolio's net assets,
however, the Board has currently limited aggregate payments under the Plans to
0.50% per annum of the Portfolio's net assets. The Portfolio's Service Class
Shares are not currently making payments for distribution fees, however the
Portfolio does pay service fees at an annual rate of 0.25% of the average
daily value of Service Class Shares owned by clients of the Service Agents.
 
F. ACCOUNT SERVICES: The UAM Funds entered into an Account Services Agreement
(the "Services Agreement") with UAM Retirement Plan Services, Inc. ("Service
Provider"), a wholly-owned subsidiary of UAM. Under the Services Agreement,
the Service Provider agrees to perform certain services for participants in a
self-directed, defined contribution plan, and for whom the Service Provider
provides participant recordkeeping. Pursuant to the Services Agreement, the
Service Provider is entitled to receive, after the end of each month, a fee at
the annual rate of 0.15% of the average aggregate daily net asset value of
shares of the UAM Funds in the accounts for which they provide services.
 
G. TRUSTEES' FEES: Each Trustee, who is not an officer or affiliated person,
receives $2,000 per meeting attended, which is allocated proportionally among
the active portfolios of UAM Funds, plus a quarterly retainer of $150 for each
active portfolio of the UAM Funds and reimbursement of expenses incurred in
attending Trustee meetings.
 
H. PURCHASES AND SALES: For the six months ended October 31, 1997, the
Portfolio made purchases of $13,697,043 and sales of $13,741,268 of investment
securities other than long-term U.S. Government and short-term securities.
There were no purchases or sales of long-term U.S. Government securities.
 
I. LINE OF CREDIT: The Portfolio, along with certain other Portfolios of UAM
Funds, collectively entered into an agreement which enables them to
participate in a $100 million unsecured line of credit with several banks.
Borrowings will be made solely to temporarily finance the repurchase of
Capital shares. Interest is charged to each participating Portfolio based on
its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%.
In addition, a commitment fee of 0.08% per annum, payable at the end of each
calendar quarter, is accrued by each participating Portfolio based on its
average daily unused portion of the line of credit. During the six months
ended October 31, 1997, the Portfolio had no borrowings under the agreement.
 
J. OTHER: At October 31, 1997, 54.6% and 79.0% of total shares outstanding
were held by 3 and 3 record shareholders of the Institutional Class Shares and
the Institutional Service Class Shares, respectively, owning more than 10% of
the aggregate total shares outstanding.
 
At October 31, 1997, the net assets of the Portfolio were substantially
comprised of foreign denominated securities and currency. Changes in currency
exchange rates will affect the value of and investment income from such
securities and currency.
 
Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of U.S. dollar denominated
transactions as a result of, among other factors, the possibly lower level of
governmental supervision and regulation of foreign securities markets and the
possibility of political or economic instability.

                            HANSON EQUITY PORTFOLIO
 
                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

UAM Funds Trust and UAM Funds, Inc. (collectively the "UAM Funds") are
registered under the Investment Company Act of 1940, as amended. The Hanson
Equity Portfolio (the "Portfolio"), a portfolio of UAM Funds Trust, is a
diversified, open-end management investment company. At October 31, 1997, the
UAM Funds were comprised of forty-two active portfolios. The financial
statements of the remaining portfolios are presented separately. The objective
of the Hanson Equity Portfolio is to achieve maximum long-term total return,
consistent with reasonable risk to principal, by investing in a diversified
portfolio of equity securities, primarily the common stock of large, U.S.-
based companies with outstanding financial characteristics and strong growth
prospects that can be purchased at reasonable valuations.
 
A. SIGNIFICANT ACCOUNTING POLICIES: The following significant accounting
policies are in conformity with generally accepted accounting principles. Such
policies are consistently followed by the Portfolio in the preparation of its
financial statements. Generally accepted accounting principles may require
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results may differ from
those estimates.
 
  1. SECURITY VALUATION: Securities listed on a securities exchange for which
  market quotations are readily available are valued at the last quoted sales
  price as of the close of the exchange on the day the valuation is made or,
  if no sale occurred on such day, at the bid price on such day. Price
  information on listed securities is taken from the exchange where the
  security is primarily traded. Over-the-counter and unlisted securities are
  valued at the current bid price. Short-term investments that have remaining
  maturities of sixty days or less at time of purchase are valued at
  amortized cost, if it approximates market value. The value of other assets
  and securities for which no quotations are readily available is determined
  in good faith at fair value using methods determined by the Board of
  Trustees.
 
  2. FEDERAL INCOME TAXES: It is the Portfolio's intention to qualify as a
  regulated investment company under Subchapter M of the Internal Revenue
  Code and to distribute all of its taxable income. Accordingly, no provision
  for Federal income taxes is required in the financial statements.
 
  3. REPURCHASE AGREEMENTS: In connection with transactions involving
  repurchase agreements, the Portfolio's custodian bank takes possession of
  the underlying securities, the value of which exceeds the principal amount
  of the repurchase transaction, including accrued interest. To the extent
  that any repurchase transaction exceeds one business day, the value of the
  collateral is monitored on a daily basis to determine the adequacy of the
  collateral. In the event of default on the obligation to repurchase, the
  Portfolio has the right to liquidate the collateral and apply the proceeds
  in satisfaction of the obligation. In the event of default or bankruptcy by
  the other party to the agreement, realization and/or retention of the
  collateral or proceeds may be subject to legal proceedings.
 
  Pursuant to an Exemptive Order issued by the Securities and Exchange
  Commission, the UAM Funds may transfer their daily uninvested cash balances
  into a joint trading account which invests in one or more repurchase
  agreements. This joint repurchase agreement is covered by the same
  collateral requirements as discussed above.
 
  4. DISTRIBUTIONS TO SHAREHOLDERS: The Portfolio will normally distribute
  substantially all of its net investment income quarterly. Any realized net
  capital gains will be distributed annually. All distributions are recorded
  on ex-dividend date.
 
 
                                       8
<PAGE>
 
                            HANSON EQUITY PORTFOLIO
 
            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)
  The amount and character of income and capital gain distributions to be
  paid are determined in accordance with Federal income tax regulations which
  may differ from generally accepted accounting principles.
 
  Permanent book-tax differences, if any, are not included in ending
  undistributed net investment income (loss) for the purpose of calculating
  net investment income (loss) per share in the financial highlights.
 
  5. OTHER: Security transactions are accounted for on trade date, the date
  the trade was executed. Costs used in determining realized gains and losses
  on the sale of investment securities are based on the specific
  identification method. Dividend income is recorded on the ex-dividend date.
  Interest income is recognized on the accrual basis. Most expenses of the
  UAM Funds can be directly attributed to a particular portfolio. Expenses
  which cannot be directly attributed are apportioned among the portfolios of
  the UAM Funds based on their relative net assets. Custodian fees for the
  Portfolio have been increased to include expense offsets, if any, for
  custodian balance credits.
 
B. ADVISORY SERVICES: Under the terms of an investment advisory agreement,
Hanson Investment Management Company (the "Adviser"), a wholly-owned
subsidiary of United Asset Management Corporation ("UAM"), provides investment
advisory services to the Portfolio at a monthly fee calculated at an annual
rate of 0.70% of average daily net assets for the month.
 
C. ADMINISTRATION SERVICES: UAM Fund Services, Inc. (the "Administrator"), a
wholly-owned subsidiary of UAM, provides and oversees administrative, fund
accounting, dividend disbursing and transfer agent services to the UAM Funds
under a Fund Administration Agreement (the "Agreement"). Pursuant to the
Agreement, the Administrator is entitled to receive annual fees, computed
daily and payable monthly, of 0.19% of the first $200 million of the combined
aggregate net assets; plus 0.11% of the next $800 million of the combined
aggregate net assets; plus 0.07% of the next $2 billion of the combined
aggregate net assets; plus 0.05% of the combined aggregate net assets in
excess of $3 billion. The fees are allocated among the portfolios of the UAM
Funds on the basis of their relative net assets and are subject to a graduated
minimum fee schedule per portfolio which rises from $2,000 per month, upon
inception of a portfolio, to $70,000 annually after two years. For portfolios
with more than one class of shares, the minimum annual fee increases to
$90,000. In addition, the Administrator receives a Portfolio-specific monthly
fee at an annual rate of 0.04% of average daily net assets of the Portfolio.
The Administrator has entered into a Mutual Funds Service Agreement with Chase
Global Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan
Bank, under which CGFSC agrees to provide certain services, including but not
limited to, administration, fund accounting, dividend disbursing and transfer
agent services. Pursuant to the Mutual Funds Service Agreement, the
Administrator pays CGFSC a monthly fee. For the period October 2, 1997
(commencement of operations) to October 31, 1997, $2,268 was paid to CGFSC for
its services.
 
D. CUSTODIAN: The Chase Manhattan Bank ("the Bank"), an affiliate of CGFSC, is
custodian for the Portfolio's assets held in accordance with the custodian
agreement.
 
E. DISTRIBUTION SERVICES: UAM Fund Distributors, Inc. (the "Distributor"), a
wholly-owned subsidiary of UAM, distributes the shares of the Portfolio. The
Distributor does not receive any fee or other compensation with respect to the
Portfolio.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)

F. TRUSTEES' FEES: Each Trustee, who is not an officer or affiliated person,
receives $2,000 per meeting attended, which is allocated proportionally among
the active portfolios of UAM Funds, plus a quarterly retainer of $150 for each
active portfolio of the UAM Funds, and reimbursement of expenses incurred in
attending Trustee meetings.
 
G. PURCHASES AND SALES: For the period October 2, 1997 (commencement of
operations) to October 31, 1997, the Portfolio made purchases of $20,130,911
and sales of $316,905 of investment securities other than long-term U.S.
Government and short-term securities. There were no purchases or sales of
long-term U.S. Government securities.
 
H. OTHER: At October 31, 1997, 100.0% of total shares outstanding were held by
one record shareholder.

Dear Shareholders:
 
October 31, 1997 is the end of the semi-annual reporting period for the
Chicago Asset Management Value/Contrarian Portfolio for equity investors and
the Intermediate Bond Portfolio for our fixed income clients. This letter will
review the investment environment, strategies and returns for the Portfolios.
We thank you for your confidence in our investment expertise and look forward
to maintaining a long-term relationship.
 
CHICAGO ASSET MANAGEMENT VALUE/CONTRARIAN PORTFOLIO
 
For the six months ended October 31, 1997, the equity market continued its
strong advance and produced a return of 15.16% as measured by the Standard and
Poor's 500 Index. This Portfolio modestly underperformed the Index in this
six-month period producing a rate of return of 13.68% net of expenses.
 
During this six-month period, the market experienced some meaningful
gyrations. In the early months, it appreciated on a continued bull market path
and even accelerated into July. In August, the market showed a sharp pullback
and notable rotation whereby some of the formerly strong performance of growth
issues faded, and the market showed some enhanced favoritism to the
value/contrarian types of issues held in this Portfolio.
 
During the past six months, we have been moderately active implementing our
disciplined approach. We have added issues, such as Amgen, Electronic Data
Systems, and Enron. Each had substantially underperformed the market prior to
our purchase. Each held unique characteristics which we viewed as offering
identifiable reasons for the past difficulties and potential for future
outperformance. We also sold current holdings in the Portfolio. Nordstrom was
sold in its entirety, having fully reached our objectives. After
underperforming earlier in the year, it went on to substantially outperform
the market before finally being sold. Apple Computer and Ethyl Corporation
were sold in their entirety due to a more clouded future outlook. However,
additional Apple shares had been purchased during a deep price decline in July
and then the entire holding was sold after a strong price rally in August.
This combination of rebalancing by buying into weakness and selling into
strength is part of our ongoing activity which offers the potential for
enhanced returns over time.
 
We have no way of knowing at this time whether the market rotation in the
direction of favoring our long-term value/contrarian style will continue in
the near future or is simply a blip along the way. In any event, we find this
style to be appropriate and valuable over time. The characteristics of the
Portfolio and the natural attractiveness of purchasing securities during times
of weakness and selling when they have returned to market leaders seems to
offer a common sense approach in addition to attractive, potential long-term
results.
 
We are committed to maintaining our careful discipline in seeking out
additional opportunities to purchase issues which in our view are undervalued.
We believe the inherent attractiveness of this strategy holds the additional
benefit of offering an ideal diversification strategy for individuals invested
in other funds with different styles.
 
CHICAGO ASSET MANAGEMENT INTERMEDIATE BOND PORTFOLIO
 
The six month period ended October 31, 1997 was favorable for fixed income
investors. The decline in interest rates produced capital appreciation along
with interest income. The Portfolio returned 5.10%.
 
As the Portfolio's fiscal year began, long-term Treasury yields approached 7%.
The market was anticipating further tightening by the Federal Open Market
Committee. The U.S. economy has enjoyed excellent growth
 
                                       1
<PAGE>
 
coupled with expanding employment opportunities. America has continued to
benefit from low inflation and astonishing record U.S. Treasury receipts.
These developments laid the foundation for further declines in interest rates
and an excellent environment for investors in high quality U.S. domestic
corporate bonds.
 
During this period, the Federal Open Market Committee has maintained an
unchanged policy with Fed Funds at 5 1/2%.
 
Chicago Asset Management's objective is to look for continued opportunities to
add income to the Portfolio while maintaining safety and liquidity. Emphasis
is placed on U.S. Treasury and Agency Notes and obligations of large U.S.
corporations.
 
The Portfolio had the following characteristics relative to the Lehman
Brothers Intermediate Government/Corporate Index as of October 31, 1997:

CHICAGO ASSET MANAGEMENT COMPANY
 
                     DEFINITION OF THE COMPARATIVE INDICES
                     -------------------------------------

The S&P 500 Index is an unmanaged index composed of 400 industrial, 40
financial, 40 utilities and 20 transportation stocks.
 
The Lehman Brothers Intermediate Government/Corporate Index is an unmanaged
index composed of a combination of the Lehman Government Bond Intermediate and
Lehman Corporate Bond Intermediate Indices. All issues are investment grade
(BBB) or higher with maturities of one to ten years and an outstanding par
value of at least $100 million for U.S. Government issues and $25 million for
others. The Government Index includes public obligations of the U.S. Treasury,
issues of Government agencies, and corporate debt backed by the U.S.
government. The Corporate Bond Index includes fixed-rate nonconvertible
corporate debt. Also included are Yankee bonds and nonconvertible debt issued
by or guaranteed by foreign or international governments and agencies. Any
security downgraded during the month is held in the index until month-end and
then removed. All returns are market value weighted inclusive of accrued
income.
 
Comparisons of performance assume reinvestment of dividends.
 
The investment results presented in the Adviser's letter represent past
performance and should not be construed as a guarantee of future results. If
the Adviser didn't have temporary fee waivers and didn't assume expenses on
behalf of the Portfolios, total returns would have been lower. The investment
return and principal value of an investment will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost.
 
Please note that one cannot invest in an unmanaged index.

                  CHICAGO ASSET MANAGEMENT COMPANY PORTFOLIOS
 
                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
UAM Funds Trust and UAM Funds, Inc. (collectively the "UAM Funds") are
registered under the Investment Company Act of 1940, as amended. The Chicago
Asset Management Value/Contrarian Portfolio and Chicago Asset Management
Intermediate Bond Portfolio (the "Portfolios"), portfolios of UAM Funds Trust,
are diversified, open-end management investment companies. At October 31,
1997, the UAM Funds were comprised of forty-two active portfolios. The
financial statements of the remaining portfolios are presented separately. The
objective of the Chicago Asset Management Value/Contrarian Portfolio is to
provide capital appreciation by investing primarily in the common stock of
large companies. The objective of the Chicago Asset Management Intermediate
Bond Portfolio is to provide a high level of current income consistent with
moderate interest rate exposure by investing primarily in investment grade
bonds with an average weighted maturity between 3 and 10 years.
 
A. SIGNIFICANT ACCOUNTING POLICIES: The following significant accounting
policies are in conformity with generally accepted accounting principles. Such
policies are consistently followed by the Portfolios in the preparation of
their financial statements. Generally accepted accounting principles may
require management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results may differ
from those estimates.
 
  1. SECURITY VALUATION: Securities listed on a securities exchange for which
  market quotations are readily available are valued at the last quoted sales
  price as of the close of the exchange on the day the valuation is made or,
  if no sale occurred on such day, at the bid price on such day. Price
  information on listed securities is taken from the exchange where the
  security is primarily traded. Over-the-counter and unlisted securities are
  valued at the current bid price. Fixed income securities are stated on the
  basis of valuations provided by brokers and/or a pricing service which uses
  information with respect to transactions in fixed income securities,
  quotations from dealers, market transactions in comparable securities and
  various relationships between securities in determining value. Short-term
  investments that have remaining maturities of sixty days or less at time of
  purchase are valued at amortized cost, if it approximates market value. The
  value of other assets and securities for which no quotations are readily
  available is determined in good faith at fair value using methods
  determined by the Board of Trustees.
 
  2. FEDERAL INCOME TAXES: It is each Portfolio's intention to qualify as a
  regulated investment company under Subchapter M of the Internal Revenue
  Code and to distribute all of its taxable income. Accordingly, no provision
  for Federal income taxes is required in the financial statements.
 
  3. REPURCHASE AGREEMENTS: In connection with transactions involving
  repurchase agreements, the Portfolios' custodian bank takes possession of
  the underlying securities, the value of which exceeds the principal amount
  of the repurchase transaction, including accrued interest. To the extent
  that any repurchase transaction exceeds one business day, the value of the
  collateral is monitored on a daily basis to determine the adequacy of the
  collateral. In the event of default on the obligation to repurchase, the
  Portfolios have the right to liquidate the collateral and apply the
  proceeds in satisfaction of the obligation. In the event of default or
  bankruptcy by the other party to the agreement, realization and/or
  retention of the collateral or proceeds may be subject to legal
  proceedings.
 
  Pursuant to an Exemptive Order issued by the Securities and Exchange
  Commission, the UAM Funds may transfer their daily uninvested cash balances
  into a joint trading account which invests in one or more
 
                                      15
<PAGE>
 
                  CHICAGO ASSET MANAGEMENT COMPANY PORTFOLIOS
 
            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)
  repurchase agreements. This joint repurchase agreement is covered by the
  same collateral requirements as discussed above.
 
  4. DISTRIBUTIONS TO SHAREHOLDERS: Each Portfolio will normally distribute
  substantially all of its net investment income quarterly. Any realized net
  capital gains will be distributed annually. All distributions are recorded
  on ex-dividend date.
 
  The amount and character of income and capital gain distributions to be
  paid are determined in accordance with Federal income tax regulations which
  may differ from generally accepted accounting principles. These differences
  are primarily due to differing book and tax treatments in the timing of the
  recognition of gains or losses on investments and in-kind transactions.
 
  Permanent book-tax differences, if any, are not included in ending
  undistributed net investment income (loss) for the purpose of calculating
  net investment income (loss) per share in the financial highlights.
 
  5. ORGANIZATION COST: Costs incurred by each Portfolio in connection with
  its organization have been deferred and are being amortized on a straight-
  line basis over a five-year period.
 
  6. OTHER: Security transactions are accounted for on trade date, the date
  the trade was executed. Costs used in determining realized gains and losses
  on the sale of investment securities are based on the specific
  identification method. Dividend income is recorded on the ex-dividend date.
  Interest income is recognized on the accrual basis. Discounts and premiums
  on securities purchased are amortized using the effective yield basis over
  their respective lives. Most expenses of the UAM Funds can be directly
  attributed to a particular portfolio. Expenses which cannot be directly
  attributed are apportioned among the portfolios of the UAM Funds based on
  their relative net assets. Custodian fees for the Portfolios have been
  increased to include expense offsets, if any, for custodian balance
  credits.
 
B. ADVISORY SERVICES: Under the terms of an investment advisory agreement,
Chicago Asset Management Company (the "Adviser"), a wholly-owned subsidiary of
United Asset Management Corporation ("UAM"), provides investment advisory
services to the Portfolios at a monthly fee calculated at an annual rate of
average daily net assets for the month, as follows:
 
<TABLE>
<CAPTION>
CHICAGO ASSET MANAGEMENT COMPANY PORTFOLIOS                               RATE
- -------------------------------------------                              ------
<S>                                                                      <C>
Value/Contrarian........................................................ 0.625%
Intermediate Bond.......................................................  0.48%
</TABLE>
 
Until further notice, the Adviser has voluntarily agreed to waive a portion of
its advisory fees and to assume expenses, if necessary, in order to keep the
Portfolios' total annual operating expenses (excluding interest, taxes and
extraordinary expenses), after the effect of expense offset arrangements, from
exceeding 0.95% and 0.80% of average daily net assets, respectively.
 
C. ADMINISTRATION SERVICES: UAM Fund Services, Inc. (the "Administrator"), a
wholly-owned subsidiary of UAM, provides and oversees administrative, fund
accounting, dividend disbursing and transfer agent services to the UAM Funds
under a Fund Administration Agreement (the "Agreement"). Pursuant to the
Agreement, the Administrator is entitled to receive annual fees, computed
daily and payable monthly, of 0.19% of the first $200
 
                                      16

million of the combined aggregate net assets; plus 0.11% of the next $800
million of the combined aggregate net assets; plus 0.07% of the next $2
billion of the combined aggregate net assets; plus 0.05% of the combined
aggregate net assets in excess of $3 billion. The fees are allocated among the
portfolios of the UAM Funds on the basis of their relative net assets and are
subject to a graduated minimum fee schedule per portfolio which rises from
$2,000 per month, upon inception of a portfolio, to $70,000 annually after two
years. For portfolios with more than one class of shares, the minimum annual
fee increases to $90,000. In addition, the Administrator receives a Portfolio-
specific monthly fee at an annual rate of 0.06% of average daily net assets of
the Chicago Asset Management Value/Contrarian Portfolio and 0.04% of average
daily net assets of the Chicago Asset Management Intermediate Bond Portfolio.
The Administrator has entered into a Mutual Funds Service Agreement with Chase
Global Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan
Bank, under which CGFSC agrees to provide certain services, including but not
limited to, administration, fund accounting, dividend disbursing and transfer
agent services. Pursuant to the Mutual Funds Service Agreement, the
Administrator pays CGFSC a monthly fee.
 
For the six months ended October 31, 1997, CGFSC was paid the following
amounts by the Administrator:

Distributor does not receive any fee or other compensation with respect to the
Portfolios.
 
F. ACCOUNT SERVICES: The UAM Funds entered into an Account Services Agreement
(the "Services Agreement") with UAM Retirement Plan Services, Inc. ("Service
Provider"), a wholly-owned subsidiary of UAM. Under the Services Agreement,
the Service Provider agrees to perform certain services for participants in a
self-directed, defined contribution plan, and for whom the Service Provider
provides participant recordkeeping. Pursuant to the Services Agreement, the
Service Provider is entitled to receive, after the end of each month, a fee at
the annual rate of 0.15% of the average aggregate daily net asset value of
shares of the UAM Funds in the accounts for which they provide services.
 
G. TRUSTEES' FEES: Each Trustee, who is not an officer or affiliated person,
receives $2,000 per meeting attended, which is allocated proportionally among
the active portfolios of UAM Funds, plus a quarterly retainer of $150 for each
active portfolio of the UAM Funds, and reimbursement of expenses incurred in
attending Trustee meetings.

I. LINE OF CREDIT: The Chicago Asset Management Intermediate Bond Portfolio,
along with certain other Portfolios of UAM Funds, collectively entered into an
agreement which enables them to participate in a $100 million unsecured line
of credit with several banks. Borrowings will be made solely to temporarily
finance the repurchase of Capital shares. Interest is charged to each
participating Portfolio based on its borrowings at a rate per annum equal to
the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.08% per
annum, payable at the end of each calendar quarter, is accrued by each
participating Portfolio based on its average daily unused portion of the line
of credit. During the six months ended October 31, 1997, the Chicago Asset
Management Intermediate Bond Portfolio had no borrowings under the agreement.

                            OCTOBER 31, 1997 REVIEW
 
To the Shareholders:
 
  The Jacobs International Octagon Portfolio (the "Portfolio") was started on
January 2, 1997 as part of the UAM Funds Trust. The Portfolio seeks to provide
long-term capital appreciation by investing in equity securities of companies
in developed and emerging markets. The Portfolio may invest across the market
capitalization spectrum, although it intends to emphasize smaller
capitalization stocks. As Investment Adviser of the Portfolio, we are pleased
to provide you with the following Management's Discussion and Analysis for the
six-month period ended October 31, 1997.
 
  The six-month performance for the Portfolio was 4.47%, versus the MSCI EAFE
Index of 3.15%. For the period January 2, 1997 to October 31, 1997 (since
inception) the Portfolio returned 6.25%, net fees, versus the MSCI EAFE Index
of 2.17%.
 
ECONOMIC AND MARKET CONDITIONS
 
 Europe
 
  While economic growth in Europe is being artificially held back by fiscal
constraints in the lead up to EMU, there are increasing signs of an
improvement in economic outlook. The apparent improvement in consumer
confidence throughout the region is leading to the prospect of a sustained
acceleration in the recovery and a potential return to above trend growth in
many parts of Europe for the first time since 1994. GDP growth is expected to
be buoyant throughout the region in 1997 with growth forecasts ranging from
between +4% to 4.5% in the UK and Scandinavia to rates of +2.2 to 2.3% in
Germany and France.
 
 Asia
 
  The Asian currency turmoil continues and we expect to see near term economic
growth rates for the region to be downgraded, as the region enters into a
period of consolidation and economic adjustment, driven by a change in the
exchange rate regime. Political leadership and timely effective implementation
of necessary reforms will be key factors watched by investors.
 
 Latin America
 
  GDP forecasts for 1997 in the region have been revised up on the back of a
buoyant recovery in both Mexico and Argentina. Overall GDP growth in the
region is forecast at around +5% for 1997. Brazil is the only country with
diminishing short term economic prospects as the cost of defending the "Real"
with high interest rates could push the economy into recession. Inflationary
trends are also positive with the regional rate expected to improve to around
12% in 1997 and fall further to just over 10% in 1998 after being at over 21%
last year.
 
  Jacobs continues to use our bottom-up value approach for investing this and
all of our portfolios. During the period our top five country holdings
included United Kingdom, France, Japan, Mexico, and Hong Kong. These five
holdings made up 40.0% of the total portfolio. The Portfolio was split
approximately 53.3% large cap issues and 36.3% small cap issues. We have
defined small cap to be companies with market capitalization less than $1
billion. The Portfolio reflected 56.7% developed markets and 22.0% emerging
markets. The balance of the Portfolio contains the cash position of 21.3%. The
cash position at the end of the period was unusually high as the portfolio had
received a large injection of new investment funds to take advantage of the
weakness in international markets. Subsequently, the funds were put to work
and now currently, as of the date of this letter, cash is now less than 10% of
the total portfolio.
 
CURRENT OUTLOOK
 
  We continue to believe that there is better value outside the United States
than within and are on the margin finding more opportunities in smaller
companies rather than larger ones. This is particularly true in Europe where
the markets have done well but the small caps have lagged and are at least
several multiples less on a P/E basis than their large cap brethren. Regarding
emerging Europe, Russia has been one of the best performing markets
 
                                       1
<PAGE>
 
in the world, up over 150% in 1997, and we continue to see on a long-term
basis a bright outlook, however there could be a pull-back at any time as the
market is ahead of itself. In eastern Europe it is very hard to find value at
the moment, as some of the countries are going through a retrenchment, such as
the Czech Republic, and to some degree, Poland.
 
  In Latin America we continue to be overweighted and think that the prospects
will remain good and that there has been a fundamental change in the way that
business and governments operate in Latin America. However, they are still
emerging markets, and we do not believe that they should achieve the same
valuation level as developed markets. The Mexican economy is getting stronger,
which has been reflected in share prices, but we continue to have a strong
interest in Mexico. We are nervous about the short-term prospects for the
Brazilian market and have reduced our exposure.
 
  Asia has been the trouble spot in 1997 particularly Southeast Asia. There
has been a melt-down in Thailand, Malaysia, Indonesia, Philippines, Singapore,
Korea and Hong Kong/China. We believe that it is too early in most of the
countries, however, we feel like we are getting close to having an investment
opportunity, particularly in Indonesia, where the Rupia has been depreciated
well below its fair value and we should see a rebound in currency at some
point in time. However, there will be a lot of pain caused by the devaluation
of the currencies in Southeast Asia and it will not be a v-shaped recovery. On
the margin we have been very underweighted in Southeast Asia, outside of Hong
Kong and China and we will be looking for opportunities to add. Thailand is
the one market where stocks have probably been beaten up about as much as they
are going to go. It is a difficult market in which to invest because Thailand
has a limited number of good companies. The biggest sector is financial, which
is still a question mark, regarding the bad debt situation. Hong Kong and
China have recently been very weak based on fears of a devaluation of the Hong
Kong dollar. We believe the currency will hold, but at the price of an
economic slowdown. The problem with Hong Kong reflects a period of loose money
and negative interest rates for a number of years, which created an over-
priced real-estate market. We expect real-estate prices to come off perhaps
20% which would impact the property sector and the financial sector, a big
part of the Hong Kong market. Although we are exposed in Hong Kong and China,
we view them as good long-term prospects. The short-term concern regarding
China, is the level of debt of state-owned companies to the state-owned
banking system which could force China to slow its economy to correct this
imbalance. In the long-term, China is the main growth engine of Asia. Our
total exposure in both markets is around 10%. Japan remains an underweight,
although we continue to look at the small caps with an increased intensity as
they have under-performed remarkably.
 
  In general we think that there are many opportunities outside of the United
States, on a bottom up stock-picking basis, and are finding more value in the
smaller caps at this point in time.
 
  In summary, we believe the Portfolio is well-positioned with good value
based ideas.
 
  Thank you for your continued confidence in Jacobs Asset Management and the
Jacobs International Octagon Portfolio.

                      DEFINITION OF THE COMPARATIVE INDEX
 
The Morgan Stanley Capital International EAFE Index is an unmanaged index
composed of arithmetic, market value weighted averages of the performance of
over 900 securities listed on the stock exchanges of countries in Europe,
Australia and the Far East.
 
Comparisons of performance assume reinvestment of dividends.
 
The investment results presented in the Adviser's letter represent past
performance and should not be construed as a guarantee of future results. If
the Adviser didn't have temporary fee waivers and didn't assume expenses on
behalf of the Portfolio, total return for the Portfolio would have been lower.
The investment 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. For a complete discussion of the risks associated with
international investing, please refer to the Portfolio's Prospectus.
 
Please note that one cannot invest in an unmanaged index.

                    JACOBS INTERNATIONAL OCTAGON PORTFOLIO
 
                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
UAM Funds Trust and UAM Funds, Inc. (collectively the "UAM Funds") are
registered under the Investment Company Act of 1940, as amended. The Jacobs
International Octagon Portfolio (the "Portfolio"), a portfolio of UAM Funds
Trust, is a diversified, open-end management investment company. At October
31, 1997, the UAM Funds were comprised of forty-two active portfolios. The
financial statements of the remaining portfolios are presented separately. The
objective of the Jacobs International Octagon Portfolio is to provide long-
term capital appreciation by investing in equity securities of companies in
developed and emerging markets.
 
A. SIGNIFICANT ACCOUNTING POLICIES: The following significant accounting
policies are in conformity with generally accepted accounting principles. Such
policies are consistently followed by the Portfolio in the preparation of its
financial statements. Generally accepted accounting principles may require
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results may differ from
those estimates.
 
  1. SECURITY VALUATION: Securities listed on a securities exchange for which
  market quotations are readily available are valued at the last quoted sales
  price as of the close of the exchange on the day the valuation is made or,
  if no sale occurred on such day, at the bid price on such day. Price
  information on listed securities is taken from the exchange where the
  security is primarily traded. Over-the-counter and unlisted securities are
  valued at the current bid price. Quotations of foreign securities and other
  assets in a foreign currency are converted to U.S. dollar equivalents. The
  converted value is based upon the bid price of the foreign currency against
  U.S. dollars quoted by any major bank or by a broker. Short-term
  investments that have remaining maturities of sixty days or less at time of
  purchase are valued at amortized cost, if it approximates market value. The
  value of other assets and securities for which no quotations are readily
  available is determined in good faith at fair value using methods
  determined by the Board of Trustees.
 
  2. FEDERAL INCOME TAXES: It is the Portfolio's intention to qualify as a
  regulated investment company under Subchapter M of the Internal Revenue
  Code and to distribute all of its taxable income. Accordingly, no provision
  for Federal income taxes is required in the financial statements.
 
  The Portfolio may be subject to taxes imposed by countries in which it
  invests. Such taxes are generally based on either income or gains earned or
  repatriated. The Portfolio accrues such taxes when the related income or
  gains are earned.
 
  3. REPURCHASE AGREEMENTS: In connection with transactions involving
  repurchase agreements, the Portfolio's custodian bank takes possession of
  the underlying securities, the value of which exceeds the principal amount
  of the repurchase transaction, including accrued interest. To the extent
  that any repurchase transaction exceeds one business day, the value of the
  collateral is monitored on a daily basis to determine the adequacy of the
  collateral. In the event of default on the obligation to repurchase, the
  Portfolio has the right to liquidate the collateral and apply the proceeds
  in satisfaction of the obligation. In the event of default or bankruptcy by
  the other party to the agreement, realization and/or retention of the
  collateral or proceeds may be subject to legal proceedings.
 
  Pursuant to an Exemptive Order issued by the Securities and Exchange
  Commission, the UAM Funds may transfer their daily uninvested cash balances
  into a joint trading account which invests in one or more repurchase
  agreements. This joint repurchase agreement is covered by the same
  collateral requirements as discussed above.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)
  4. FOREIGN CURRENCY TRANSLATION: The books and records of the Portfolio are
  maintained in U.S. dollars. Investment securities and other assets and
  liabilities denominated in a foreign currency are translated into U.S.
  dollars on the date of valuation. The Portfolio does not isolate that
  portion of realized or unrealized gains and losses resulting from changes
  in the foreign exchange rate from fluctuations arising from changes in the
  market prices of the securities. These gains and losses are included in net
  realized and unrealized gain and loss on investments on the statement of
  operations. Net realized and unrealized gains and losses on foreign
  currency transactions represent net foreign exchange gains or losses from
  disposition of foreign currencies, currency gains or losses realized
  between trade and settlement dates on securities transactions and the
  difference between the amount of the investment income and foreign
  withholding taxes recorded on the Portfolio's books and the U.S. dollar
  equivalent amounts actually received or paid.
 
  5. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS: The Portfolio may enter
  into forward foreign currency exchange contracts to protect the value of
  securities held and related receivables and payables against changes in
  future foreign exchange rates. A forward currency contract is an agreement
  between two parties to buy and sell currency at a set price on a future
  date. The market value of the contract will fluctuate with changes in
  currency exchange rates. The contract is marked-to-market daily using the
  current forward rate and the change in market value is recorded by the
  Portfolio as unrealized gain or loss. The Portfolio recognizes realized
  gain or loss when the contract is closed, equal to the difference between
  the value of the contract at the time it was opened and the value at the
  time it was closed. Risks may arise upon entering into these contracts from
  the potential inability of counterparties to meet the terms of their
  contracts and are generally limited to the amount of unrealized gain on the
  contracts, if any, at the date of default. Risks may also arise from the
  unanticipated movements in the value of a foreign currency relative to the
  U.S. dollar.
 
  6. DISTRIBUTIONS TO SHAREHOLDERS: The Portfolio will normally distribute
  substantially all of its net investment income quarterly. Any realized net
  capital gains will be distributed annually. All distributions are recorded
  on ex-dividend date.
 
  The amount and character of income and capital gain distributions to be
  paid are determined in accordance with Federal income tax regulations which
  may differ from generally accepted accounting principles. These differences
  are primarily due to differing book and tax treatments for foreign currency
  transactions.
 
  Permanent book-tax differences, if any, are not included in ending
  undistributed net investment income (loss) for the purpose of calculating
  net investment income (loss) per share in the financial highlights.
 
  7. OTHER: Security transactions are accounted for on trade date, the date
  the trade was executed. Costs used in determining realized gains and losses
  on the sale of investment securities are based on the specific
  identification method. Dividend income is recorded on the ex-dividend date,
  except that certain dividends from foreign securities are recorded as soon
  as the Portfolio is informed of the ex-dividend date. Interest income is
  recognized on the accrual basis. Most expenses of the UAM Funds can be
  directly attributed to a particular portfolio. Expenses which cannot be
  directly attributed are apportioned among the portfolios of the UAM Funds
  based on their relative net assets. Custodian fees for the Portfolio have
  been increased to include expense offsets, if any, for custodian balance
  credits.

B. ADVISORY SERVICES: Under the terms of an investment advisory agreement,
Jacobs Asset Management (the "Adviser") provides investment advisory services
to the Portfolio at a monthly fee calculated at an annual rate of 1.00% of
average daily net assets for the month. The Adviser has voluntarily agreed to
waive a portion of its advisory fees and to assume expenses, if necessary, in
order to keep the Portfolio's total annual operating expenses, after the
effect of expense offset arrangements, from exceeding 1.75% of average daily
net assets. United Asset Management Corporation ("UAM") is a limited partner
of the Adviser.
 
C. ADMINISTRATION SERVICES: UAM Fund Services, Inc. (the "Administrator"), a
wholly-owned subsidiary of UAM, provides and oversees administrative, fund
accounting, dividend disbursing and transfer agent services to the UAM Funds
under a Fund Administration Agreement (the "Agreement"). Pursuant to the
Agreement, the Administrator is entitled to receive annual fees, computed
daily and payable monthly, of 0.19% of the first $200 million of the combined
aggregate net assets; plus 0.11% of the next $800 million of the combined
aggregate net assets; plus 0.07% of the next $2 billion of the combined
aggregate net assets; plus 0.05% of the combined aggregate net assets in
excess of $3 billion. The fees are allocated among the portfolios of the UAM
Funds on the basis of their relative net assets and are subject to a graduated
minimum fee schedule per portfolio which rises from $2,000 per month, upon
inception of a portfolio, to $70,000 annually after two years. For portfolios
with more than one class of shares, the minimum annual fee increases to
$90,000. In addition, the Administrator receives a Portfolio-specific monthly
fee at an annual rate of 0.04% of average daily net assets of the Portfolio.
The Administrator has entered into a Mutual Funds Service Agreement with Chase
Global Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan
Bank, under which CGFSC agrees to provide certain services, including but not
limited to, administration, fund accounting, dividend disbursing and transfer
agent services. Pursuant to the Mutual Funds Service Agreement, the
Administrator pays CGFSC a monthly fee. For the six months ended October 31,
1997, $29,393 was paid to CGFSC for its services.
 
D. CUSTODIAN: The Chase Manhattan Bank (the "Bank"), an affiliate of CGFSC, is
custodian for the Portfolio's assets held in accordance with the custodian
agreement.
 
E. DISTRIBUTION SERVICES: UAM Fund Distributors, Inc. (the "Distributor"), a
wholly-owned subsidiary of UAM, distributes the shares of the Portfolio. The
Distributor does not receive any fee or other compensation with respect to the
Portfolio.
 
F. ACCOUNT SERVICES: The UAM Funds entered into an Account Services Agreement
(the "Services Agreement") with UAM Retirement Plan Services, Inc. ("Service
Provider"), a wholly-owned subsidiary of UAM. Under the Services Agreement,
the Service Provider agrees to perform certain services for participants in a
self-directed, defined contribution plan, and for whom the Service Provider
provides participant recordkeeping. Pursuant to the Services Agreement, the
Service Provider is entitled to receive, after the end of each month, a fee at
the annual rate of 0.15% of the average aggregate daily net asset value of
shares of the UAM Funds in the accounts for which they provide services.
 
G. TRUSTEES' FEES: Each Trustee, who is not an officer or affiliated person,
receives $2,000 per meeting attended, which is allocated proportionally among
the active portfolios of UAM Funds, plus a quarterly retainer of $150 for each
active portfolio of the UAM Funds and reimbursement of expenses incurred in
attending Trustee meetings.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)
 
H. PURCHASES AND SALES: For the six months ended October 31, 1997, the
Portfolio made purchases of $41,007,350 and sales of $8,168,453 of investment
securities other than long-term U.S. Government and short-term securities.
There were no purchases or sales of long-term U.S. Government securities.
 
I. LINE OF CREDIT: The Portfolio, along with certain other Portfolios of UAM
Funds, collectively entered into an agreement which enables them to
participate in a $100 million unsecured line of credit with several banks.
Borrowings will be made solely to temporarily finance the repurchase of
Capital shares. Interest is charged to each participating Portfolio based on
its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%.
In addition, a commitment fee of 0.08% per annum, payable at the end of each
calendar quarter, is accrued by each participating Portfolio based on its
average daily unused portion of the line of credit. During the six months
ended October 31, 1997, the Portfolio had no borrowings under the agreement.
 
J. OTHER: At October 31, 1997, 48.4% of total shares outstanding were held by
3 record shareholders owning more than 10% of the aggregate total shares
outstanding.
 
At October 31, 1997, the net assets of the Portfolio were substantially
comprised of foreign denominated securities. Changes in currency exchange
rates will affect the value of and investment income from such securities.
 
Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of U.S. dollar denominated
transactions as a result of, among other factors, the possibly lower level of
governmental supervision and regulation of foreign securities markets and the
possibility of political or economic instability.

                               SEMI-ANNUAL REPORT
                                OCTOBER 31, 1997
<PAGE>
 
Dear Fellow Shareholders:
 
  The equity markets experienced a strong bull market and a 10% correction for
the six month period ended October 31, 1997. As has been the pattern since the
crash of 1987, every 10% decline in the market is followed by a bargain-
hunting session of individual investors who don't want to miss the bull
market. Unlike ten years ago when the market crashed and institutions didn't
know if individuals would run for the exits, this time it was pretty clear
that individuals were running, for the entrances. The Dow Jones Industrial
Average and the S&P 500 Index posted gains of 7.12% and 15.16%, respectively,
while the TJ Core Equity Portfolio produced gains of 15.17%.
 
  Market valuation levels continue to be stretched above and beyond historical
ranges, and assume that companies will continue to show good earnings
comparisons even as sales slow and internal expenses rise. As has been written
in the past, the Portfolio has been structured defensively to do better in a
choppier environment than one in which there is only smooth sailing. As a
result, the Portfolio's increasingly defensive portfolio outperformed the
broader market indices for the six months ended October 31, 1997.
 
  The fiscal quarter ended October 31, 1997 showed more signs of increasing
volatility in the domestic equity and international markets and only a muted
response from the fixed income markets. The fixed income markets continue to
watch Federal Reserve Chairman Greenspan react to a strong economy with no
consumer inflation by doing nothing. Greenspan frets about wages rising but
also fears a tightening since the Southeast Asian countries' financial markets
are in a state of chaos and gold prices continue to decline to $300/oz.--both
highly deflationary indicators. Hence, Greenspan turns his attention to the
equity markets and worries that they are too exuberant. The markets are
slightly less exuberant after their fearful downdraft brought to us in living
color by CNBC with fears of a market meltdown. For the quarter ended October
31, 1997, the TJ Core Equity Portfolio outperformed the S&P 500 Index with a
decline of only 0.48% versus a decline of 3.75% in the S&P 500 and 9.09% in
the Dow Jones Industrial Average.
 
  The Adviser has taken advantage of the increasing volatility and used this
opportunity to cut back some of the Portfolio's positions that had a
substantial move, eliminate positions we received in spin-offs and reinvest
the proceeds to increase current holdings or purchase new positions in more
attractively valued stocks. During the six months ended October 31, 1997, the
Portfolio reduced positions in USX-U.S. Steel Group, Ford Motor, Cooper
Industries, Union Camp, AT&T, Southwest Airlines, ITT Industries, H&R Block,
and Waste Management. The Portfolio eliminated spin-off holdings in Cognizant,
ACNielsen, and NCR Corporation. The proceeds from these sales were used to
purchase new positions in Allergan, Jostens, Raytheon, Limited, Union Pacific,
Johnson & Johnson, American Home Products, AMP, Boeing, and McDonald's.
 
  The recent volatility in stock prices is expected to continue as momentum
investors jump from one market segment to another in search of the level of
performance enjoyed in recent years. In our view, returns similar to the
recent year's outstanding gains are not likely, as the economic outlook
becomes more uncertain and earnings advances become more difficult to
maintain. As a result, the Adviser will continue to emphasize the defensive
posture of the TJ Core Equity Portfolio and will use instances of increasing
volatility as opportunities to accumulate undervalued companies with favorable
long-term prospects.

                     DEFINITION OF THE COMPARATIVE INDICES
                     ------------------------------------- 

The Dow Jones Industrial Average Index is a price weighted average of 30 blue-
chip stocks that are generally the leaders in their industry and are listed on
the New York Stock Exchange.
 
The S&P 500 Index is an unmanaged index composed of 400 industrial, 40
financial, 40 utilities and 20 transportation stocks.
 
Comparisons of performance assume reinvestment of dividends.
 
The investment results presented in the Adviser's letter represent past
performance and should not be construed as a guarantee of future results. If
the Adviser did not have temporary fee waivers and did not assume expenses on
behalf of the Portfolio, total return for the Portfolio would have been lower.
The investment 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.
 
Please note that one cannot invest in an unmanaged index.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
UAM Funds Trust and UAM Funds, Inc. (collectively the "UAM Funds") are
registered under the Investment Company Act of 1940, as amended. The TJ Core
Equity Portfolio (the "Portfolio"), a portfolio of UAM Funds Trust, is a
diversified, open-end management investment company. At October 31, 1997, the
UAM Funds were comprised of forty-two active portfolios. The financial
statements of the remaining portfolios are presented separately. The objective
of the TJ Core Equity Portfolio is to provide maximum total return consistent
with reasonable risk to principal by investing in the common stock of quality
companies with lower valuations in sectors of the economy exhibiting strong,
or improving relative performance.
 
  A. SIGNIFICANT ACCOUNTING POLICIES: The following significant accounting
policies are in conformity with generally accepted accounting principles. Such
policies are consistently followed by the Portfolio in the preparation of its
financial statements. Generally accepted accounting principles may require
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results may differ from
those estimates.
 
    1. SECURITY VALUATION: Securities listed on a securities exchange for
  which market quotations are readily available are valued at the last quoted
  sales price as of the close of the exchange on the day the valuation is
  made or, if no sale occurred on such day, at the bid price on such day.
  Price information on listed securities is taken from the exchange where the
  security is primarily traded. Over-the-counter and unlisted securities are
  valued at the current bid price. Short-term investments that have remaining
  maturities of sixty days or less at time of purchase are valued at
  amortized cost, if it approximates market value. The value of other assets
  and securities for which no quotations are readily available is determined
  in good faith at fair value using methods determined by the Board of
  Trustees.
 
    2. FEDERAL INCOME TAXES: It is the Portfolio's intention to qualify as a
  regulated investment company under Subchapter M of the Internal Revenue
  Code and to distribute all of its taxable income. Accordingly, no provision
  for Federal income taxes is required in the financial statements.
 
    3. REPURCHASE AGREEMENTS: In connection with transactions involving
  repurchase agreements, the Portfolio's custodian bank takes possession of
  the underlying securities, the value of which exceeds the principal amount
  of the repurchase transaction, including accrued interest. To the extent
  that any repurchase transaction exceeds one business day, the value of the
  collateral is monitored on a daily basis to determine the adequacy of the
  collateral. In the event of default on the obligation to repurchase, the
  Portfolio has the right to liquidate the collateral and apply the proceeds
  in satisfaction of the obligation. In the event of default or bankruptcy by
  the other party to the agreement, realization and/or retention of the
  collateral or proceeds may be subject to legal proceedings.
 
    Pursuant to an Exemptive Order issued by the Securities and Exchange
  Commission, the UAM Funds may transfer their daily uninvested cash balances
  into a joint trading account which invests in one or more repurchase
  agreements. This joint repurchase agreement is covered by the same
  collateral requirements as discussed above.
 
    4. DISTRIBUTIONS TO SHAREHOLDERS: The Portfolio will normally distribute
  substantially all of its net investment income quarterly. Any realized net
  capital gains will be distributed annually. All distributions are recorded
  on ex-dividend date.
 
 
                                       9
<PAGE>
 
                           TJ CORE EQUITY PORTFOLIO
 
            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)

    The amount and character of income and capital gain distributions to be
  paid are determined in accordance with Federal income tax regulations which
  may differ from generally accepted accounting principles. These differences
  are primarily due to differing book and tax treatments in the timing of the
  recognition of gains or losses on investments.
 
    Permanent book-tax differences, if any, are not included in ending
  undistributed net investment income (loss) for the purpose of calculating
  net investment income (loss) per share in the financial highlights.
 
    5. OTHER: Security transactions are accounted for on trade date, the date
  the trade was executed. Costs used in determining realized gains and losses
  on the sale of investment securities are based on the specific
  identification method. Dividend income is recorded on the ex-dividend date.
  Interest income is recognized on the accrual basis. Most expenses of the
  UAM Funds can be directly attributed to a particular portfolio. Expenses
  which cannot be directly attributed are apportioned among the portfolios of
  the UAM Funds based on their relative net assets. Custodian fees for the
  Portfolio have been increased to include expense offsets, if any, for
  custodian balance credits.
 
  B. ADVISORY SERVICES: Under the terms of an investment advisory agreement,
Tom Johnson Investment Management, Inc. (the "Adviser"), a wholly-owned
subsidiary of United Asset Management Corporation ("UAM"), provides investment
advisory services to the Portfolio at a monthly fee calculated at an annual
rate of 0.75% of average daily net assets for the month. Through January 1,
1999, the Adviser has voluntarily agreed to waive a portion of its advisory
fees and to assume expenses, if necessary, in order to keep the Portfolio's
total annual operating expenses, after the effect of expense offset
arrangements, from exceeding 1.25% of average daily net assets.
 
  C. ADMINISTRATION SERVICES: UAM Fund Services, Inc. (the "Administrator"), a
wholly-owned subsidiary of UAM, provides and oversees administrative, fund
accounting, dividend disbursing and transfer agent services to the UAM Funds
under a Fund Administration Agreement (the "Agreement"). Pursuant to the
Agreement, the Administrator is entitled to receive annual fees, computed
daily and payable monthly, of 0.19% of the first $200 million of the combined
aggregate net assets; plus 0.11% of the next $800 million of the combined
aggregate net assets; plus 0.07% of the next $2 billion of the combined
aggregate net assets; plus 0.05% of the combined aggregate net assets in
excess of $3 billion. The fees are allocated among the portfolios of the UAM
Funds on the basis of their relative net assets and are subject to a graduated
minimum fee schedule per portfolio which rises from $2,000 per month, upon
inception of a portfolio, to $70,000 annually after two years. For portfolios
with more than one class of shares, the minimum annual fee increases to
$90,000. In addition, the Administrator receives a Portfolio-specific monthly
fee at an annual rate of 0.04% of average daily net assets of the Portfolio.
The Administrator has entered into a Mutual Funds Service Agreement with Chase
Global Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan
Bank, under which CGFSC agrees to provide certain services, including but not
limited to, administration, fund accounting, dividend disbursing and transfer
agent services. Pursuant to the Mutual Funds Service Agreement, the
Administrator pays CGFSC a monthly fee. For the six months ended October 31,
1997, $28,791 was paid to CGFSC for its services.
 
  D. CUSTODIAN: The Chase Manhattan Bank (the "Bank"), an affiliate of CGFSC,
is custodian for the Portfolio's assets held in accordance with the custodian
agreement.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)

  E. DISTRIBUTION SERVICES: UAM Fund Distributors, Inc. (the "Distributor"), a
wholly-owned subsidiary of UAM, distributes the shares of the Portfolio. The
Porfolio has adopted Distribution and Service Plans (the "Plans") pursuant to
Rule 12b-1 under the Investment Company Act of 1940. Under the Plans, the
Portfolio may not incur distribution and service fees which exceed an annual
rate of 0.75% of the Portfolio's net assets, however, the Board has currently
limited aggregate payments under the Plans to 0.50% per annum of the
Portfolio's net assets. The Portfolio is not currently making payments for
distribution fees, however the Portfolio does pay service fees at an annual
rate of 0.25% of the average daily value of shares owned by clients of the
Service Agents.
 
  F. ACCOUNT SERVICES: The UAM Funds entered into an Account Services
Agreement (the "Services Agreement") with UAM Retirement Plan Services, Inc.
("Service Provider"), a wholly-owned subsidiary of UAM. Under the Services
Agreement, the Service Provider agrees to perform certain services for
participants in a self-directed, defined contribution plan, and for whom the
Service Provider provides participant recordkeeping. Pursuant to the Services
Agreement, the Service Provider is entitled to receive, after the end of each
month, a fee at the annual rate of 0.15% of the average aggregate daily net
asset value of shares of the UAM Funds in the accounts for which they provide
services.
 
  G. TRUSTEES' FEES: Each Trustee, who is not an officer or affiliated person,
receives $2,000 per meeting attended, which is allocated proportionally among
the active portfolios of UAM Funds, plus a quarterly retainer of $150 for each
active portfolio of the UAM Funds, and reimbursement of expenses incurred in
attending Trustee meetings.
 
  H. PURCHASES AND SALES: For the six months ended October 31, 1997, the
Portfolio made purchases of $5,470,659 and sales of $851,891 of investment
securities other than long-term U.S. Government and short-term securities.
There were no purchases or sales of long-term U.S. Government securities.
 
  I. LINE OF CREDIT: The Portfolio, along with certain other Portfolios of UAM
Funds, collectively entered into an agreement which enables them to
participate in a $100 million unsecured line of credit with several banks.
Borrowings will be made solely to temporarily finance the repurchase of
Capital shares. Interest is charged to each participating Portfolio based on
its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%.
In addition, a commitment fee of 0.08% per annum, payable at the end of each
calendar quarter is accrued by each participating Portfolio based on its
average daily unused portion of the line of credit. During the six months
ended October 31, 1997, the Portfolio had no borrowings under the agreement.
 
  J. OTHER: At October 31, 1997, 62.5% of total shares outstanding were held
by 3 record shareholders owning more than 10% of the aggregate total shares
outstanding.
