Dear Fellow Shareholder:

     Overall, it was a tumultuous time for both U.S. and international stock
markets since last year's annual report. Market performance tends to be
cyclical, and in various cycles, certain investment styles may fall in and out
of favor. The investment climate for the past year has been difficult for small
cap and value strategies. Though it has been a trying year, we did not change
our investment strategy. We believe that the current market environment is not
sustainable and does not signal the kind of fundamental change in the long-term
drivers of equity returns that would lead us to change our investment strategy
which focuses on fundamental values.

     The fiscal year was an unusual one. Although historically, on average, the
stocks of smaller companies tend to outperform those of large companies, and low
price-to-earnings stocks tend to outperform high price-to-earnings stocks(1),
this past year was the exact opposite. The larger and more expensive (in terms
of price relative to earnings) a company was, the better it fared. Investment
performance for the Funds for the year ended March 31, 1999, depended
significantly on a few factors such as capitalization, trading activity and
growth versus value. Our exposure to small cap domestic and international
stocks, low turnover stocks and our value bias hurt the Funds' performance. The
one-year returns for the International Small Capitalization and Japan Funds were
slightly better than the Funds' benchmarks(2). Please see the Financial
Highlights for performance information.

     In light of the current volatility in the equity markets, we think it
important for our shareholders to understand certain aspects of the risk of
investing in the Barr Rosenberg Market Neutral Fund(3). The risks can be divided
into two broad categories: the risk that arises from investing with a particular
manager (manager risk) and the risk associated with certain investment styles
(investment risk). Manager risk is simply the risk, to the investor, of placing
assets with an individual investment manager. By investing with a manager, you
are placing your trust in the firm's investment process, trading ability and a
host of other manager-specific attributes.

     Investment risk refers to the portfolio investments. The stock selection
models used by AXA Rosenberg Investment Management LLC, the Funds' manager,
result in portfolios with particular style characteristics. The most notable
characteristic of the Barr Rosenberg Market Neutral Fund portfolio is the net
bias toward stocks with traditional value characteristics (lower
price-to-earnings or price-to-book ratios, for example) and away from high
trading activity stocks. These investment style biases have had a negative
impact on the Fund returns over the most recent quarters.

     Market risk, which is related to investment risk, usually refers to the
relationship between a fund's portfolio and the market as a whole. The
traditional expression of that relationship is beta, which measures changes in a
fund's portfolio return in relation to changes in the return of a broad
portfolio of investments or the "market". A goal of the Barr Rosenberg Market
Neutral Fund is to build a portfolio which has a beta close to zero. This is not
to say that the portfolio isn't risky, but rather that the return variances
simply do not follow the same pattern of the "market" as a whole.

                                        1
<PAGE>   2

     A market neutral type fund is often viewed as an asset class of its own and
may be a compliment to bond, stock and real estate investing. Because market
neutral funds hold short positions, it is recommended that investors develop a
solid understanding of the risks inherent in shorting a stock. Many market
neutral managers have witnessed increased volatility in the daily value of their
portfolios over the last year. Market neutral does not mean risk neutral. Market
neutral investment strategies can lose a significant amount of principal.

     During the past year, we were pleased to welcome Dwight M. Jaffee as a
Trustee to the Barr Rosenberg Series Trust. Dr. Jaffee is the Willis H. Booth
Professor of Banking and Finance at the Haas School of Business, University of
California, Berkeley.

     You can obtain more information about the Funds by calling (800) 447-3332
and following the voice prompts or visiting our new web site www.brmf.com which
we expect to be operational by June 30, 1999.

     We appreciate the confidence and trust you have demonstrated with your
investments in the Barr Rosenberg Mutual Funds.

                                         Sincerely,
                                         /s/ Richard L. Saalfeld
                                         Richard L. Saalfeld

                                         President & CEO

(1) Based on research studies done by AXA Rosenberg Investment Management LLC.

(2) Past performance is no guarantee of future results.

(3) Investment in shares of the Barr Rosenberg Market Neutral Fund is more
    volatile and risky than some other forms of investments. Since the Fund has
    both a long and a short portfolio, an investment in the Barr Rosenberg
    Market Neutral Fund will involve risks associated with twice the number of
    investment decisions made for a typical stock fund. These types of funds
    typically have a high portfolio turnover that could increase transaction
    costs and cause short-term capital gains to be realized. While it may be the
    intent of the Manager to take long positions in stocks that outperform the
    market and short positions in stocks that underperform the market, in
    various market climates, there is no assurance that the Manager will be
    successful. Small capital funds typically carry additional risks since
    smaller companies generally have experienced a greater degree of volatility
    than average.

BARR ROSENBERG SERIES TRUST
U.S. SMALL CAPITALIZATION SERIES
- --------------------------------------------------------------------------------

MARKET COMMENTARY

     Small capitalization stocks fell sharply in the year ended March 31, 1999,
substantially lagging the strong rise in large capitalization stocks. For the
year ended March 31, 1999, the Russell 2000(1) fell 16.26% while the S&P 500(2)
rose 18.44%. The weakness in small capitalization stocks relative to the larger
capitalization stocks reached levels not seen since the 1930s. Within the small
cap sector, growth stocks surged tremendously (as opposed to value stocks)
beginning in the fall of 1998. For the year ended March 31, 1999, the Russell
2000 Growth Index(3) topped the Russell 2000 Value Index(4) by 11.52%.

     More recently, the superior performance of small cap growth stocks relative
to small cap value stocks has been unprecedented. In the October 1, 1998,
through March 31, 1999, period, the Russell 2000 Growth Index outpaced the
Russell 2000 Value Index by 23.1%, the largest spread for any six-month period
since Russell began the index in 1979. Since the October 8, 1998, bottom of the
small cap market, the dominance of growth stocks is even more extreme. From
October 8, 1998, through March 31, 1999, the Russell 2000 Growth Index rose
49.1%, which was 38.6% above the Russell 2000 Value Index and almost 15
percentage points better than the rise in the S&P 500.

     Within the small cap growth segment, the most actively traded stocks have
fared the best. In environments when actively traded growth stocks are leading
the market by such a wide margin, our modest value orientation (reflected in
lower earnings-to-price and book-to-price profiles than the Russell 2000) and
our tendency to hold less actively traded stocks negatively impacted the Fund's
performance relative to the Russell 2000. Historically, these most actively
traded growth stocks underperform the market because their earnings typically
fail to live up to the expectations embedded in their current prices.

PORTFOLIO REPORT

     From a performance attribution perspective, much of the Fund's
underperformance relative to its benchmark for the year ended March 31, 1999,
was attributable to holding less actively traded stocks relative to the Russell
2000. Overall, the differences between the industry weightings of the Fund and
the Russell 2000 Index hurt the performance of the Fund. Modest overexposure to
the strong performing Service industry (3.12% above the Russell 2000 weight)
helped the Fund's performance relative to the Russell 2000 Index. On the
negative side, underexposure to the strong performing Telephone (3.01% below the
Russell 2000 weight), Real Estate Assets (2.18% below the Russell 2000 weight)
and Electric Utilities (1.07% below the Russell 2000 weight) industries hurt the
Fund's relative performance.

     It is important to note that the differences in risk factors and industry
exposures between the Fund and its benchmark, the Russell 2000 Index, are
modest. In addition, these exposures are the result of the Manager's bottom-up
stock selection models and not top-down predictions of the returns for risk
factors or industries. Over time, the return contribution from these exposures
is expected to be small relative to the independent contribution from stock
selection.

     Small capital funds typically carry additional risks since smaller
companies have experienced a greater degree of volatility than average.

     Past performance is no guarantee of future results.

MARKET COMMENTARY

     The Japanese equity market has surged more than 27%(1) since the bottom of
the market in October 1998. Lacking convincing fundamental signals, the
investors most puzzled by the recent exuberance in the market are probably the
Japanese themselves. While individual investors were active in the Japanese OTC
market, the powerful driving force behind the recent bull market was actually
orchestrated by foreign investors.

     The main factor that sparked the fierce buying by foreigners was the hope
that the Japanese economy had finally found its way out of a long and dark
tunnel. There is no doubt that foreigners are more optimistic about the mid-term
prospects of the Japanese economy than the Japanese themselves, at least at this
moment. The question is whether the current foreign-driven sentiment can inspire
confidence across the broad market or alternatively, whether the market might
see another short-term illusion as it did in the beginning of 1998.

     The risk profiles of the current market and the early 1998 market are quite
different. In early 1998, the drivers for returns were those stocks with
negative relative strength and low valuation. In the current market, the drivers
for returns are those stocks with high price-to-earnings, high relative strength
and high valuation. These stocks are not necessarily momentum stocks as they
were in 1997 to 1998.

     Recent changes in government policies and the reversal of the equity market
raised significant questions about the optimal allocation of Japanese wealth.
The under-weight in the equity market by Japanese individuals is actually much
more extreme than that of foreigners. In a financial market where the deposit
rate is virtually zero, and the yield of the intermediate bond is well below 2%,
there should be ample incentive for Japanese individuals to pursue higher risk
assets in the equity market. The current boom of the Japanese OTC market is, in
our view, a prelude to that kind of sentiment among individual investors.

     In many aspects, today's Japanese equity market resembles the U.S. market
in the 1980s. During that period, the U.S. economic recovery was spurred by
dramatic reforms in corporate taxes, the pension system and industry
deregulation, furthered by corporate efforts on restructuring. The Japanese
equity market is said to lag the U.S. market by 10 years. Will Japan's recovery
follow the same route as the U.S. market recovery in the 1980s? That depends on
whether the plans on the table can be implemented in an efficient way as in the
U.S. experience.

PORTFOLIO REPORT

     For the year ending March 31, 1999, the Fund slightly outperformed its
benchmark, the Tokyo Stock Price Index of the Tokyo Stock Exchange (TOPIX)(2).
The strength of the yen during the second half of the year contributed more than
12% in the Japan equity dollar returns.

     The Fund's performance was attributable to holding under-valued stocks as
identified by the Manager's stock selection models and stocks with themes
related to corporate restructuring and re-engineering. Over the year, the
Manager's value-based strategy worked well in the large and medium
capitalization sectors but under-performed the benchmark in the small
capitalization sector where stocks with low trading activity were still under
selling pressure -- a very similar situation to what we observed in the U.S.
market.

     International investing involves increased risk and volatility. Total
return includes change in share price and reinvestment of distributions. The
Japan Series may be subject to the additional risk of non-diversified regional
fund investing.

     Past performance is no guarantee of future results.

INTERNATIONAL SMALL CAPITALIZATION SERIES
- --------------------------------------------------------------------------------

MARKET COMMENTARY

     The international markets went through a tumultuous year. We had witnessed
extreme market volatility globally. The Economic Monetary Union (EMU) in Europe,
the continued weakness in the Asian markets and the long-awaited small stock
recovery were the predominant themes in international markets over the past
year.

     After enjoying a spectacular 17% return in the first quarter of 1998,
international small stocks, as measured by the Cazenove Rosenberg Global Smaller
Companies Index excluding the U.S. (CRIexUS)(1), were subsequently dragged down
by worries over the world economy. Concerns over the financial crises in Asia,
Latin America and Russia created a mini market crash in August 1998. As a
result, international small stocks lost over 20% during the second and third
quarters alone. In the fourth quarter, as investor regained confidence, we
experienced a strong rebound of over 10% in small stocks around the world.

     During the first quarter of 1999, the world markets posted modest positive
gains. The threat of a global financial crisis and a world recession finally
abated due to the collaborative efforts from financial experts worldwide.
Investors' confidence continued to improve. The low interest rate, low inflation
environment provided a further stabilizing force for the financial markets.
However, this optimism was overshadowed by the war in Kosovo. For the year ended
March 31,1999, international small stocks lost 11.3%. During the same period,
international large stocks, as measured by the Morgan Stanley Capital
International Europe, Australasia and Far East Standard Index (MSCI Standard
EAFE), gained 6.4%. This large performance disparity between large and small
stocks was in part a reflection of investors' anxiety over world politics and
the global economy. This sentiment of uncertainty led to a flight to quality,
where investors focused mostly on blue-chip companies.

     The European nations had achieved remarkable economic progress over the
last two years in an effort to qualify for EMU. Investors applauded the economic
reforms and responded positively to the overall expansion of the European
economy supported by a declining interest rate environment. After enjoying
spectacular growth in 1997 and 1998, the European markets retreated and
underperformed other developed countries in the first three months of 1999. The
euro was successfully launched on January 1. However, concerns over slowing
corporate earnings growth and the uncertainty over developments in Kosovo
prevented the markets from reaching higher levels. Since its official inception,
the euro depreciated over 8% against the U.S. dollar. On the positive side,
investors welcomed the possibility of the U.K. joining the Euroland. Domestic
demand remains strong within Europe. There is also room for further interest
rate cuts within the U.K. and Euroland, which should further stimulate the
European economy, increase consumers' confidence and domestic consumption. Small
stocks are in a good position to reap these benefits. For the year ending March
31, 1999, small stocks lost over 15%(2), while large stocks were up over 4%(2).
The underperformance of small stocks occurred primarily in the third and fourth
quarters of 1998. This flight toward large-capitalization stocks reflected
investors' uncertainty about the EMU convergence. The successful inauguration of
Euroland in January alleviated the anxiety and since then, investors have
gradually refocused on small companies. During the first quarter of 1999, small
stocks and large stocks both lost over 2%(2). Growth stocks were particularly
strong during the second and third quarters of 1998 while value stocks regained
their dominance during the fourth quarter of 1998 and the first quarter of 1999.

     The Japanese stock market experienced a dramatic turnaround between
September 1998 and March 1999. Small stocks, in particular, outperformed the
broad market over this period. For the year ending March 31, 1999, Japanese
small stocks delivered an impressive gain of over 14%(2), and large stocks
posted a 16%(2) return. Fundamentally, Japan is still in malaise. However, there
have been concrete indications that the government is making a conscious effort
to revitalize the economy. Starting April 1999, corporate accounting practices
in Japan will be converging more toward

                                       18
<PAGE>   19

international standards. In addition, the securities transaction tax will be
abolished. These are measures that encourage overseas investment in Japan and
promote accounting transparency. We have also witnessed an increasing number of
cases where companies have restructured their businesses as well as their
employed work force. Overseas investors responded favorably to these measures,
resulting in the recent stock market rally. Domestically, consumption remains
weak, despite the distribution of free shopping vouchers by the government. On
the corporate side, return on equity for most companies have been steadily
rising. During the past year, growth stocks trailed value stocks. The Japanese
yen had also undergone extreme volatility. In August 1998, the Japanese yen fell
to a low of 147 yen per U.S. dollar. The yen eventually stabilized only after
intervention from both the Japanese and U.S. governments. Since then, the yen
had continued to gain strength, attaining a level of 118 yen per U.S. dollar at
the end of March. This is an indication of improving investors' confidence in
the Japanese economy.

     In the rest of Asia, the past year had been one of the most difficult
periods in history. The Asian financial crises triggered by the devaluation of
the Thai Baht in July 1997 pervasively affected every single country in Asia.
Real estate prices plummeted, domestic consumption fell and unemployment rose.
Several countries also experienced repeated threats of currency devaluation and
stock market plunges. In an effort to defend the Hong Kong dollar, the Hong Kong
government deviated from its historical "free market" policy and intervened in
the stock market to prop up stock prices. In September 1998, the Malaysian
government surprised investors by announcing a series of controls that severely
restricted trading by foreigners. On the more positive side, lately, there have
been signs that the recession is finally bottoming out. Real estate prices in
the region have stabilized. Strong demand in the U.S. and Europe is also helping
to boost Asian exports and hence industrial activities. Forecasts for economic
activity in Asia ex Japan are now on a rising trend. However, several countries
are still contending with rising unemployment, and domestic consumption still
languishes. The recoveries are still fragile. For the year ending March 31,
1999, small stocks in the Asia ex Japan region declined 20%(2), while large
stocks suffered a loss of 6%(2). There is now increased optimism towards the
Asian markets. As a result of government supports and fund flows from overseas
investors, we have seen impressive gains in the Asia ex Japan markets since last
September.

     The historically stable Canadian market also joined in the volatility
bandwagon over the past 12 months. Concerns over the slowing Canadian economy as
a result of the Asian, Latin American and Russian economic crises caused the
Canadian dollar to reach a 10-year low against the U.S. dollar in the third
quarter of 1998. Then in the fourth quarter, renewed concerns over the
possibility of Quebec separating from the rest of Canada further weakened the
currency. In March this year, signs of a slowing economy prompted the government
to lower the discount rate. Investors applauded the move. As world commodity
prices stabilized, the Canadian dollar regained its strength against the U.S.
dollar. The stock market had also picked up healthy gains during the first
quarter of 1999. Over the past 12 months, value stocks continued to outperform
growth stocks. Small stocks lost over 22%(2) for the year ending March 31, 1999.
Large stocks declined over 12%(2).

     The foreign exchange market also experienced extreme volatility over the
past year. The Malaysian government has reverted to a fixed exchange rate regime
since September 1998. For the year ending March 31, 1999, the Japanese yen
appreciated over 12% against the U.S. dollar. The Canadian dollar suffered a
depreciation of 6%. Since its inception on January 1, the euro had depreciated
over 8% against the U.S. dollar.

PORTFOLIO REPORT

     The International Small Capitalization Series follows a systematic and
disciplined approach to international investing. Our portfolio closely tracks
the country and industry exposures of the benchmark with a diversification of
over 400 holdings in more than 21 countries. As of March 31, 1999, the top 10
holdings accounted for about 15% of the total portfolio. Approximately 70% of
the holdings were invested in Europe. Construction and Home Building, together
with

                                       19
<PAGE>   20

Metal and Machinery Products represented 18% of the portfolio. The
price-to-positive-earnings ratio of the portfolio was 12.3, and the median
market capitalization of the holdings was approximately $230 million.

     For the year ending March 31, 1999, the Fund outperformed its benchmark,
the Cazenove Rosenberg Global Smaller Companies Index excluding the U.S(1).
Since inception, the Fund's performance has also exceeded that of its benchmark.
We strive to add value through bottom-up stock selection and avoid heavy bets on
countries and industries.

OUTLOOK

     We are optimistic about the prospects of international small stock
investing. As the world economy stabilizes and continues on its growth path,
small stocks will be the main beneficiaries. Thus far in 1999, we have already
seen signs of encouraging growth from small stocks. Value stocks have also
regained leadership. Over the long run, we believe international small stocks
represent an attractive component in a diversified global portfolio.

     International investing involves increased risk and volatility. Small
capital funds typically carry additional risks since smaller companies generally
have experienced a greater degree of market volatility than average.

     Past performance is no guarantee of future results.

* Non-income producing security.
(a) Bankrupt security; valued by Management (Note 2).
(b) In September 1998, the Malaysian Government announced an imposition of
    capital controls. Although shares held in Malaysian stocks can be traded,
    shares purchased prior to September 1, 1998 need to be held until September
    1, 1999, before sales proceeds can be converted into another currency.

    On February 4, 1999, Bank Negara Malaysia, the central bank, announced a
    levy on repatriation of Malaysian ringgit (MYR) held by foreign investors.
    The levy, intended to replace the restriction on repatriation of investment
    capital that had been in place since September 1, 1998, was implemented on
    February 15, 1999.

(c) At March 31, 1999, the aggregate cost of investment securities for income
    tax purposes was $39,001,977. Cost for federal income tax purposes differs
    from value by net unrealized depreciation of securities as follows:

BARR ROSENBERG SERIES TRUST
MARKET NEUTRAL FUND
- --------------------------------------------------------------------------------

MARKET COMMENTARY

     The period since August 1998, has been a particularly difficult time for
the Fund. Over the last eight months, the market has favored high trading
activity growth stocks (stocks with the highest trailing 12-month share turnover
and the highest price-to-earnings ratio), regardless of the underlying
fundamentals associated with the issuing companies. Because the Manager's stock
selection models seeks to reconcile relative stock price with fundamental value,
the Fund has not participated in the rally associated with this small group of
high trading activity growth stocks. The Manager believes that the dominance of
this group of stocks is not sustainable and does not signal the kind of change
in the long-term drivers of equity returns that would lead to a change in the
Manager's investment strategy.

PORTFOLIO REPORT

     The portfolio consists of over 800 long securities and 500 short
securities. The portfolio is constructed so that the total long positions and
the total short positions are similar in terms of risk characteristics and have
approximately the same dollar amount invested with minimal exposure to sectors
or industries.

     Since the Manager's stock selection models focus on the fundamentals of a
company, the portfolio will have persistent modest exposures to value
characteristics, as well as a bias toward companies whose stock is
less-frequently traded. Much of the Fund's underperformance relative to its
benchmark, 3-month U.S. Treasury Bills, for the year ended March 31, 1999, was
attributable to these "style" exposures as both value and low trading activity
stocks were penalized in the market. This was particularly true during the last
part of 1998 and the first quarter of 1999.

     Investment in shares of the Barr Rosenberg Market Neutral Fund is more
volatile and risky than some other forms of investments. Since the Fund has both
a long and a short portfolio, an investment in the Barr Rosenberg Market Neutral
Fund will involve risks associated with twice the number of investment decisions
made for a typical stock fund. These types of funds typically have a high
portfolio turnover that could increase transaction costs and cause short-term
capital gains to be realized. While it may be the intent of the Manager to take
long positions in stocks that outperform the market and short positions in
stocks that underperform the market, in various market climates, there is no
assurance that the Manager will be successful.

     Since risk in the Barr Rosenberg Market Neutral Fund relates specifically
to the Manager's stock selection techniques and not to any systematic or
economy-wide factors, the proper benchmark is an asset that also has the least
exposure to systematic influences. U.S. 90-day T-bills are such an asset. An
investment in 90-day T-bills is different from an investment in the Barr
Rosenberg Market Neutral Fund because T-bills are backed by the full faith and
credit of the U.S. Government. T-bills have a fixed rate of return, and
investors do not bear the risk of losing their investment. The income received
from T-bills is free from state income tax.

     Past performance is no guarantee of future results.

DOUBLE ALPHA MARKET FUND
- --------------------------------------------------------------------------------

MARKET COMMENTARY

     The S&P 500 Index(1) rose 18.44% for the year ended March 31, 1999, while
the Russell 2500 Index(2) declined 13.26%. The past year has been marked by
investor exuberance for stocks with "compelling stories" rather than compelling
fundamentals. The market rally in the latter half of 1998 and the first quarter
of 1999 was led by large cap stocks and the growth sector.

PORTFOLIO REPORT

     The Fund invests in the Barr Rosenberg Market Neutral Fund and S&P 500
Index Futures. Investing in the Barr Rosenberg Market Neutral Fund contributed a
- -8.5% to the total return of the Fund for the period April 22, 1998 (inception
of the Fund), to March 31, 1999 while the investment in S&P 500 Index Futures
contributed positively (approximately 9.4%) to performance over this period. See
the separate commentary for the Barr Rosenberg Market Neutral Fund.

     Investment in shares of the Barr Rosenberg Market Neutral Fund is more
volatile and risky than some other forms of investments. Since the Fund has both
a long and a short portfolio, an investment in the Barr Rosenberg Market Neutral
Fund will involve risks associated with twice the number of investment decisions
made for a typical stock fund. These types of funds typically have a high
portfolio turnover that could increase transaction costs and cause short-term
capital gains to be realized. While it may be the intent of the Manager to take
long positions in stocks that outperform the market and short positions in
stocks that underperform the market, in various market climates, there is no
assurance that the Manager will be successful.

     Investment in Index Futures involves risk. Positions in Index Futures may
be closed out by the Barr Rosenberg Double Alpha Market Fund only on the futures
exchanges on which the Index Futures are then traded. There can be no assurance
that a liquid market will exist for any particular contract at any particular
time.

     Past performance does not guarantee future results.

BARR ROSENBERG SERIES TRUST
SELECT SECTORS MARKET NEUTRAL FUND
- --------------------------------------------------------------------------------

MARKET COMMENTARY

     The Barr Rosenberg Select Sectors Market Neutral Fund began operations
during the last quarter of 1998. This followed a volatile market caused by the
world financial turmoil in August and September resulting from the political
uncertainty and economic collapse of Russia and the deteriorating financial
crises in Asia. The U.S. stock market rebounded strongly in October following
the Federal Reserve's interest rate cuts. The market's upward move continued
through the first quarter of 1999 led by the largest cap stocks and growth
sectors. The U.S. market rally has been narrowly focused on growth stocks with
high price momentum, high price-earnings and high trading activity. However, the
returns for the first quarter were more volatile than in previous months. The
S&P 500 Index(1) exhibited strong positive performance in January and March but
negative performance in February. By mid-quarter investors became concerned
about the hint of returning inflation when year-end economic indicators were
reported stronger than expected. However, these concerns were short-lived.

PORTFOLIO REPORT

     The Fund takes long and short positions primarily in the 500 largest
capitalization stocks principally traded in the U.S. Unlike the Barr Rosenberg
Market Neutral Fund, under normal circumstances, the Barr Rosenberg Select
Sectors Market Neutral Fund will be overweighted in its long and short positions
in different sectors and industries based on quantitative bottom-up company
analysis.

     From inception (October 19, 1998, for Institutional shares and November 11,
1998, for Investor shares) to March 31, 1999, the Fund outperformed its
benchmark, 3-month U.S. Treasury Bills, by 2.01% and 1.69%, respectively. In
addition to the positive contribution from the exposure to relative strength
(measure of trailing 12-month price performance) during this period, the Fund
benefited from long industry exposures to autos, banks and telephones. Short
industry exposures to oils and oil services contributed negatively to
performance.

     Investment in shares of the Barr Rosenberg Select Sectors Market Neutral
Fund is more volatile and risky than some other forms of investments. Since the
Fund has both a long and a short portfolio, an investment in the Barr Rosenberg
Select Sectors Market Neutral Fund will involve risks associated with twice the
number of investment decisions made for a typical stock fund. These types of
funds typically have a high portfolio turnover that could increase transaction
costs and cause short-term capital gains to be realized. While it may be the
intent of the Manager to take long positions in stocks that outperform the
market and short positions in stocks that underperform the market, in various
market climates, there is no assurance that the Manager will be successful.

     Since risk in the Barr Rosenberg Select Sectors Market Neutral Fund relates
specifically to the Manager's stock selection techniques and not to any
systematic or economy-wide factors, the proper benchmark is an asset that also
has the least exposure to systematic influences. U.S. 90-day T-bills are such an
asset. An investment in 90-day T-bills is different from an investment in the
Barr Rosenberg Select Sectors Market Neutral Fund because T-bills are backed by
the full faith and credit of the U.S. Government. T-bills have a fixed rate of
return, and investors do not bear the risk of losing their investment. The
income received from T-bills is free from state income tax.

     Past performance is no guarantee of future results.

BARR ROSENBERG SERIES TRUST
NOTES TO FINANCIAL STATEMENTS
MARCH 31, 1999
- --------------------------------------------------------------------------------

     1. -- ORGANIZATION. Barr Rosenberg Series Trust (the "Trust") was
established as a Massachusetts business trust under the laws of Massachusetts on
April 1, 1988. The Trust is an open-end diversified management investment
company offering six portfolios: U.S. Small Capitalization Series, Japan Series,
International Small Capitalization Series, Market Neutral Fund, Double Alpha
Market Fund (commenced operations on April 22, 1998) and the Select Sectors
Market Neutral Fund (commenced operations on October 19, 1998), collectively
(the "Funds"), or individually (the "Fund"), with differing objectives and
strategies. Each Fund is authorized to issue Institutional Shares. In addition,
the U.S. Small Capitalization Series is authorized to issue Select Shares and
Adviser Shares, the Japan Series and International Small Capitalization Series
are authorized to issue Select Shares and the Market Neutral Fund, Double Alpha
Market Fund and the Select Sectors Market Neutral Fund are authorized to issue
Investor Shares. The classes differ primarily with respect to the level of
Shareholder Services Fees and Distribution Fees borne by each class. In
addition, an investor's eligibility to purchase each of the three classes of
shares generally depends on the amount invested in a particular Fund and on
whether the investor makes the investment in the Fund directly or through a
financial adviser.

     The Trustees approved the closing of the U.S. Small Capitalization Series
to new investors as of February 20, 1998, when the Fund reached $500 million in
market value. Effective, January 1, 1999, the U.S. Small Capitalization Series
was closed to all investments, except participants in 401(k) plans may continue
to purchase shares until and including June 30, 1999. Participants in certain
"wrap programs" may continue to purchase shares quarterly to rebalance their
accounts, and certain bank "asset allocation programs" may continue to purchase
shares under the terms of the agreement with the Trust.

     2. -- SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual amounts could differ from
those estimates. The following is a summary of significant accounting policies
consistently followed by the Trust in the preparation of its financial
statements.

     Security Valuation

     Portfolio securities listed on a national exchange or exchanges for which
     market quotations are available are valued at their last quoted sale price
     on each business day. If there is no such reported sale, the most recently
     quoted bid price is used for long securities and the ask price is used for
     securities sold short. Debt obligations with sixty days or less remaining
     until maturity are valued at their amortized cost. Unlisted securities for
     which market quotations are readily available are valued at the most recent
     quoted bid price for long securities and the ask price is used for
     securities sold short. Other assets and securities for which no quotation
     is readily available are valued at fair value as determined in good faith
     by the Trustees.

     Security Transactions and Related Investment Income

     Security transactions are accounted for on the trade date, with realized
     gain or loss on the sale of investments determined by using the identified
     cost method. Corporate actions (including cash dividends) are recorded on
     the ex-date or after the ex-date as the Fund becomes aware of such action,
     net of any non-refundable tax withholdings. Interest income (including
     amortization of premium and accretion of discount) is recorded as earned.

BARR ROSENBERG SERIES TRUST
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
- --------------------------------------------------------------------------------

     Foreign Currency Transactions

     The accounting records of the Funds are maintained in U.S. dollars. All
     monetary items denominated in foreign currencies are translated to U.S.
     dollars based upon the prevailing exchange rate at the close of each
     business day. Net realized gains and losses on foreign currency
     transactions represent net gains and losses from currency gains and losses
     realized between the trade and settlement dates on securities transactions,
     and the difference between the amount of net investment income accrued and
     the U.S. dollar amount actually received. Further, the effects of changes
     in foreign currency exchange rates on investments in securities are not
     segregated in the Statement of Operations from the effects of changes in
     market prices of those securities, but are included with the net realized
     gain or loss and unrealized appreciation or depreciation on investments.

     Forward Foreign Currency Contracts

     Forward foreign currency contracts are valued at the daily exchange rate of
     the underlying currency. The forward foreign currency contracts are
     adjusted by the daily exchange rate of the underlying currency and any
     gains or losses are recorded for financial statement purposes as unrealized
     appreciation or depreciation until the contractual settlement date. Gains
     or losses from the purchase or sale of forward foreign currency contracts
     are recorded as realized on the settlement date.

     Foreign Securities

     The Japan Series and the International Small Capitalization Series pursue
     their respective objectives by investing in foreign securities. There are
     certain additional risks involved when investing in foreign securities that
     are not inherent with investments in domestic securities. These risks may
     involve adverse political and economic developments and the possible
     imposition of currency exchange or other foreign governmental laws or
     restrictions.

     Futures Contracts

     The Double Alpha Market Fund pursues its respective objective by investing
     in S&P 500 Index Future contracts. An S&P 500 Index Future contract is a
     contract to buy or sell an integral number of units of the S&P 500 Index at
     a specified future date at a price agreed upon when the contract is made.
     Cash or securities are deposited with brokers in order to maintain a
     position. Subsequent payments made or received by the Fund based on the
     daily change in the market value of the position are recorded as unrealized
     appreciation or depreciation until the contract is closed out, at which
     time the gain or loss is realized.

     The use of futures contacts involves, to varying degrees, elements of
     market risk. Risks arise form the possible imperfect correlation in
     movements in the price of futures contracts, interest rates and the
     underlying hedged assets, and the possible inability of counterparties to
     meet the terms of their contracts. However, the Fund's activities in
     futures contracts are conducted through regulated exchanges which minimize
     counterparty credit risks.

     Real Estate Investment Trusts

     The Funds own shares of real estate investment trusts ("REITS") which
     report information on the source of their distributions annually.
     Distributions received from REITS during the year, which are known to be a
     return of capital, are recorded as a reduction to the cost of the
     individual REIT.

     Short Sales

     The Market Neutral Fund and Select Sectors Market Neutral Fund are
     authorized to engage in short-selling which obligates the Fund to replace
     the security borrowed by purchasing the security at current market value
     sometime in the future. The Fund will incur a loss if the price of the
     security increases between the date of the short sale and the date on which
     the Fund replaces the borrowed security. The Fund will realize a gain if
     the price of the security declines between those dates. Until the Fund
     replaces the borrowed security, the Fund will maintain a segregated account
     with cash and/or U.S. Government securities sufficient to cover its short
     position on a daily basis. At March 31, 1999, the values of securities sold
     short in the Market Neutral Fund and the Select Sectors Market Neutral Fund
     amounted to $183,544,598 and $24,649,552, against which collateral of
     $384,568,225 and $59,672,910 was held, respectively. The collateral
     includes the Bear Stearns Deposit Account, the Bear Stearns repurchase
     agreement and the securities held long, as shown in the Schedule of
     Portfolio Investments.

     Securities Lending

     Under the Security Lending Program, securities held by the U.S. Small
     Capitalization Series are loaned by State Street Bank, as agent, to certain
     brokers (the "Borrowers"). The Borrowers provided cash as collateral
     against loans in an amount at least equal to 100% of the market value of
     the loaned securities.

     At March 31, 1999, the value of securities loaned amounted to $2,332,768
     against which cash collateral of $2,752,094 was held. The cash collateral
     is invested in short-term investments and is included in the Schedule of
     Portfolio Investments. A portion of the income generated upon investment of
     the collateral is remitted to the Borrowers, and the remainder is allocated
     between the U.S. Small Capitalization Series and State Street Bank in its
     capacity as lending agent. Security lending fee income, net of related
     expenses, is recorded as earned. The U.S. Small Capitalization Series bears
     the risk of loss with respect to the investment of the cash collateral.

     Determination of Net Asset Value and Calculation of Expenses

     Expenses specific to an individual Fund are charged to that Fund, while the
     expenses that are attributable to more than one Fund of the Trust are
     allocated among the respective Funds. Net asset value per share of each
     class, investment income, realized and unrealized gains and losses and
     expenses other than class specific expenses are allocated daily to each
     class of shares based upon the proportion of shares outstanding attributed
     to each class at the beginning of each day. Distribution expenses are
     solely borne by and charged to the Select Shares and Investor Shares;
     Shareholder Services fees are charged to the Adviser Shares, Select Shares
     and Investor Shares.

     Dividends and Distributions

     Dividends and distributions to shareholders are recorded on the ex-dividend
     date. Distributions are made on a tax basis which may differ from generally
     accepted accounting principles. These differences are primarily due to
     differing treatments for foreign currency transactions, Real Estate
     Investment Trusts (REITS), redemptions-in-kind and wash sales for book and
     tax purposes. Permanent book and tax basis differences will result in
     reclassifications to capital accounts.

     Dividends and distributions to shareholders which exceed net investment
     income and net realized capital gains for financial reporting purposes but
     not for tax purposes are reported as dividends in excess of net investment
     income

     or distributions in excess of net realized gains. To the extent they exceed
     net investment income and net realized gains for tax purposes, they are
     reported as distributions of capital.

     As of March 31, 1999, the following reclassifications have been made to
     increase/(decrease) such accounts with offsetting adjustments made to
     capital:

     4.-- FEDERAL INCOME TAXES. It is each Fund's policy to comply with the
requirements of the Internal Revenue Code under Subchapter M, applicable to
regulated investment companies, and to distribute all of its taxable income,
including any net realized gain on investments, to its shareholders. Therefore,
no provision is made for federal income taxes.

     As of March 31, 1999, the U.S. Small Capitalization Series had a capital
loss carryover of $25,481,146, which will expire on March 31, 2007. The Japan
Series had a capital loss carryover of $908,755 of which $258,946, $69,379,
$15,997, $20,835, $261,584 and $282,014 will expire on March 31 of the years
2000, 2001, 2002, 2004, 2006 and 2007, respectively. The International Small
Capitalization Series had a capital loss carryover of $1,316,042, which will
expire on March 31, 2007. The Market Neutral Fund had a capital loss carryover
of $20,880,748, which will expire on March 31, 2007. Capital loss carryovers
will be available to offset future realized capital gains through the stated
years. In order to meet certain excise tax distribution requirements, each Fund
is required to measure and distribute annually, net capital gains and net
foreign currency gains realized during a twelve-month period ending October 31.
In connection with this, each Fund is permitted for tax purposes to defer into
its next fiscal year any net capital losses or net foreign currency losses
incurred between November 1 and the end of its fiscal year.

     Capital losses incurred after October 31, within a Fund's fiscal year are
deemed to arise on the first business day of the following fiscal year for tax
purposes. The following Funds have incurred and will elect to defer such capital
losses:

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Trustees of Barr Rosenberg Series Trust,
the Shareholders of U.S. Small Capitalization Series,
Japan Series, International Small Capitalization Series, Market Neutral Fund,
Double Alpha Market Fund and Select Sectors Market Neutral Fund.

     In our opinion, the accompanying statements of assets and liabilities,
including the schedules of portfolio investments and schedules of securities
sold short, and the related statements of operations and of changes in net
assets and the financial highlights present fairly, in all material respects,
the financial position of U.S. Small Capitalization Series, Japan Series,
International Small Capitalization Series, Market Neutral Fund, Double Alpha
Market Fund and Select Sectors Market Neutral Fund, each a series of Barr
Rosenberg Series Trust (the "Trust") at March 31, 1999, the results of each of
their operations, the changes in each of their net assets and their financial
highlights for the periods presented, in conformity with generally accepted
accounting principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Trust's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at March 31, 1999 by correspondence with the
custodian and brokers and the application of alternative auditing procedures
where confirmations from brokers were not received, provide a reasonable basis
of the opinion expressed above.
