Dear Fellow Shareholder:

     Technology stocks rocketed higher during 1999, carrying most U.S. stock
market indexes along with them. The overall market gained more than 20% for an
unprecedented fifth consecutive year. The market continued posting healthy
returns in the first quarter of 2000. However, by the end of the first quarter
cracks began to emerge in the mania for biotech and Internet issues. In the
first quarter, the NASDAQ suffered no less than four 10% corrections, the final
10% correction of the quarter occurred over the span of just three days.

     For the fiscal year, the International Small Capitalization Fund gained
32.04% and 31.47% for Institutional Shares and Select Shares respectively and
exceeded its benchmark, the Cazenove Rosenberg Global Small Companies Index
excluding the U.S.(1) Since inception, the Institutional Shares (September 23,
1996) and the Select Shares (October 29, 1996) have average annual returns of
6.54% and 6.28% respectively. Bullishness among stock investors was an
international phenomenon in 1999. We remain optimistic about the future for
international investing. The International Small Capitalization Fund provides
diversification for investors who are primarily invested in large capitalization
stocks and exposure to the growth potential of the mature international markets
for investors whose portfolios are concentrated in the U.S.

     The U.S. Small Capitalization Fund gained over 31% (Institutional Shares
31.36%, Adviser Shares 31.00% and Select Shares 31.06%) although the return for
the Fund's benchmark, the Russell 2000 Index(2) was 37.29% for the year ended
March 31, 2000, driven by the market's focus on growth-oriented technology
companies for most of the year. Small cap growth outperformed small cap value by
45.78%. This was in sharp contrast to the prior fiscal year when small cap value
outperformed small cap growth by 10.99%. Because the Fund has a modest value
bias, the Fund's performance suffered relative to the Russell 2000 Index in the
market environment where growth stocks so overwhelmingly dominated. Over long
periods, the returns from value and growth stocks have been similar, and they've
swapped places as market leaders many times. Over a full market cycle we are not
concerned about this modest style bias. For the 5 and 10-year periods, the
Institutional Shares have outperformed the Russell 2000 Index with average
annual returns of 19.66% and 16.17% respectively. The Adviser Shares (January
21, 1997) and the Select Shares (October 22, 1996) have average annual returns
since inception of 12.40% and 14.69% respectively.

     After an analysis and re-evaluation of current and future small cap sector
capacity utilization across all products, we decided to re-open the U.S. Small
Capitalization Series effective March 27, 2000, to all investors.

     We strongly believe that companies with superior long-term earnings will be
rewarded, on average, with superior market performance. This core belief makes
us a value investor. Does it mean that we don't like growth stocks, especially
the Internet and biotech stocks? Not at all. We are convinced that Internet and
biotech sectors will be two of the major sectors of the economy in the 21st
century. We believe that the market is too enthusiastic about these sectors and
that the earnings potential for Internet and biotech stocks, and more generally
growth stocks, does not justify the extreme valuation levels observed during
1999.

     For this reason, the year ending March 31, 2000, was a very difficult one
for our small/mid-cap market neutral strategy. Performance of the Market Neutral
Fund and the Double Alpha Market Fund, which invests in the Market Neutral Fund,
severely suffered in the extreme growth environment of the past 12 months
resulting in losses for the year. Because the stock selection models are based
on fundamental analysis, they tend to produce better results when investors
focus on the relationship between current company fundamentals and prices.

     The Select Sectors Market Neutral Fund outperformed its benchmark, U.S.
90-day Treasury Bills, with returns of 9.82% and 9.39% for the Institutional
Shares and the Investor Shares respectively. This Fund holds long and short
positions primarily in the largest 500 companies based on capitalization. It
does not have the same degree of value bias as the Market Neutral Fund. While
the Market Neutral Fund has modest industry and sector exposures, the Select
Sectors Market Neutral Fund will typically over or under weight different
sectors and industries within sectors. Since inception, the Institutional Shares
(October 19, 1998) have returned 10.43% and Investor Shares (November 11, 1998)
10.29%.

     Despite the disappointing performance of the Market Neutral and Double
Alpha Funds, we still believe that a market neutral investment strategy makes
sense for investors who are looking for a defensive strategy with the potential
for higher returns than bonds so long as the investor is willing to accept
potentially higher short-term volatility. We believe diversification is the key
to market neutral investing. An investment in both the Market Neutral Fund and
the Select Sectors Market Neutral Fund would have done better in the last year
than an investment in the Market Neutral Fund alone. We will pursue
diversification among market neutral strategies in 2000.

     The Japanese equity market was one of the best performers in the world for
the year ended March 31, 2000. Japan rebounded strongly from its economic slumps
and currency problems of 1997 and 1998. However, Japan still remains a mystery.
It seems to be a market that has the potential for great upside but also
significant downside risk. The Japan Fund gained over 45% (Institutional Shares
45.24% and Select Shares 45.04%) for the year although its benchmark, the
TOPIX(3), returned 56.48% for the same period. "Internet mania" contributed
significantly to the strong performance of the TOPIX. Because the Manager's
stock selection models are unable to reconcile current prices for these
high-flying growth stocks with underlying fundamentals, performance of the Fund
suffered. For the 5 and 10-year periods, the average annual return of the
Institutional Shares is -2.07% and 0.82% respectively. The Select Shares have an
average annual return of -0.44% since inception (October 22, 1996),

     For a more detailed discussion of performance, please see the commentary
preceding each Fund's Schedule of Portfolio Investments.

     In 2000, we expect to expand our product line to different market segments
affording investors additional opportunities to diversify their portfolios. To
take advantage of the strategic alliance between the Funds' manager and AXA,
Barr Rosenberg Mutual Funds will become AXA Rosenberg Mutual Funds in August
2000. The name of the Trust will not change.

     Our investment philosophy is founded on sound investment theory and
principles, focusing on the long-term and providing appropriate diversification.
We also strongly believe that by being a disciplined investor, by sticking to
our investment philosophy and by being patient, we will create a solid
foundation for long-term investment success.

                                         Thank you for your trust and support,

                                         /s/ Richard L. Saalfeld

     Total returns for the Institutional Shares of the U.S. Small Capitalization
Fund and the Japan Fund represent the historical performance for the Rosenberg
Series Trust Small Capitalization Fund and the Rosenberg Series Trust Japan Fund
until they were converted to the Barr Rosenberg U.S. Small Capitalization Fund
and the Barr Rosenberg Japan Fund on August 5, 1996. Performance data represents
past performance which does not guarantee future results. Investment return and
principal value may increase or decrease depending upon market, economic,
political, currency exchange rates and other conditions affecting a fund's
portfolio, so that an investor's shares, when redeemed, may be worth more or
less than their original cost.

     Small capitalization funds typically carry additional risks since smaller
companies generally have experienced a greater degree of market volatility than
average. International investing involves increased risk and volatility. The
Japan Fund may also be subject to the additional risk of non-diversified
regional investing.

     Investments in shares of the Market Neutral Fund and the Select Sectors
Market Neutral Fund are more volatile and risky than some other forms of
investments. Since the Funds have both a long and a short portfolio, an
investment in the Market Neutral Fund and the 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 risks in the Market Neutral Fund and the Select Market Neutral Fund
relate 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
Market Neutral Fund and the 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.

     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 a particular contract at any particular
time.

     Total return includes change in share price and reinvestment of
distributions. Total return set forth may reflect the waiver of a portion of the
Fund's advisory or administrative fees for certain periods since the inception
date. In such instances, and without the waiver of fees, total return would have
been lower.

</TABLE>

     For the year ended March 31, 2000, small capitalization stocks rose
strongly with the Russell 2000 Index(1) up 37.29%. A surge in small cap stocks
late in 1999 and early in 2000 brought an end to the market leadership by large
cap stocks that had persisted since 1996. All small cap stocks did not fare
equally, however, as small cap growth stocks continued to dominate small cap
value stocks. For the year ending March 31, 2000, the Russell 2000 Growth
Index(2) rose 61.96% compared with a rise of just 12.03% for the Russell 2000
Value Index(3). In general, investors richly rewarded the most actively traded,
highest price momentum growth stocks most strongly associated with the "new
economy" stories.

     This market environment was a difficult one for the performance of the Fund
relative to the Russell 2000 Index. The Manager's stock selection models tend to
favor stocks that are seen as underpriced relative to their fundamental
financial characteristics when compared with other similar stocks. This tendency
leads to a portfolio with a modest value bias. In such an extreme growth
environment, this value bias hurt the relative performance of the Fund.

     While the Fund's value exposures detracted from relative performance, other
risk factor and industry exposures contributed positively to performance. The
Fund's slight positive exposure to stocks with positive price momentum (relative
strength risk factor) helped the most as the return associated with this feature
of stocks rose to historic highs. Among industries, an overexposure to the
electronics industry (2.8% above the Russell 2000 Index exposure) during the
past 12 months boosted relative performance.

     The bulk of the Fund's underperformance was attributable to the independent
effect of stock selection and not the aggregate influence of risk factor and
industry exposures. This result is not surprising given the Fund's tight
management of risk factor and industry exposures and given the types of stocks
that were rewarded and punished by investors over the past 12 months.
Fundamental to the Manager's stock selection process is the belief that a
portfolio of stocks that produce more future earnings per dollar of initial cost
(an "earnings advantage") than the benchmark should be rewarded with above
benchmark performance. In the past year, the stocks held by the Fund did
consistently produce more future earnings per dollar of cost than the benchmark;
however, investors did not reward these superior earnings. In fact, investors
strongly favored stocks with no earnings or negative earnings. In environments
like these, when investors do not focus on reconciling current stock prices with
likely future earnings or other fundamental measures of value, the Manager's
stock selection performance will suffer.

     Total returns for the Institutional Shares represents the historical
performance for the Rosenberg Series Trust Small Capitalization Fund which was
launched in February 1989 until it was converted to the Barr Rosenberg U.S.
Small Capitalization Fund on August 5, 1996.

     Performance data represents past performance which does not guarantee
future results. Investment return and principal value may increase or decrease
depending upon market conditions so that an investor's shares, when redeemed,
may be worth more or less than their original cost.

     Small capitalization funds typically carry additional risks since smaller
companies generally have experienced a greater degree of market volatility than
average. Total return includes change in share price and reinvestment of
distributions.

     Total return set forth reflects the waiver of a portion of the Fund's

</TABLE>

     The broader Japanese equity market, as measured by the TOPIX(1), delivered
a 56.48% return for the year ended March 31, 2000, making the Japanese equity
market one of best performers in the world. While the stronger yen contributed
more than 15% to return, the TOPIX posted a 35.54% gain in local currency and
stabilized itself above the 1,600 level.

     Although tepid, investors saw an indication of improvement in corporate
earnings. According to latest survey by Toyo Keizai Inc., consolidated net
profits for Tokyo Stock Exchange First Section non-financial firms are expected
to rise 58% for the fiscal year 2000 versus a 65% decline in fiscal year 1999,
despite substantial write-offs for restructuring of expenses and special losses
resulting from new accounting standards.

     However, strong earnings growth was not evenly spread across all sectors.
In fact only 7 out of 34 Tokyo Stock Exchange defined industries outperformed
the TOPIX for the year. Securities (+196%), communications (+192%), wholesale
(+144%), services (+138%) and electric machinery (+108%) were the top
performers. The companies in these industries are either booming "new economy"
stocks or cyclical stocks that benefit from a rosier economic picture. The worst
performers were those stocks in aged industries that have not provided a good
story for growth-hungry investors. Mining (-33%), construction (-20%) and many
basic industries were the laggards amid the bull market.

     The Fund gained more than 45% but under-performed its benchmark, the TOPIX,
by more than 11% for the year ended March 31, 2000. The unprecedented
performance spread between growth stocks and value stocks, especially during the
second half of the year as high flying large growth stocks drove the market,
created an unfavorable market environment for the Fund. Stock selection and the
portfolio's negative exposure to relative strength (measure of trailing 12-month
price performance) were the major contributors to the Fund's underperformance.
The Manager's stock selection models, based on fundamental analysis, favor value
stocks. In a momentum market, driven by growth stocks with relative strength,
the models are unable to reconcile current prices with the underlying company
fundamentals.

     Total returns for the Institutional Shares represents the historical
performance for the Rosenberg Series Trust Japan Fund which was launched in
February 1989 until it was converted to the Barr Rosenberg Japan Fund on August
5, 1996. Return and principal value may increase or decrease depending upon
market, economic, political, currency exchanges rates and other conditions
affecting a fund's portfolio so that an investor's shares, when redeemed, may be
worth more or less than their original cost.

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

     Total return set forth reflects the waiver of a portion of the Fund's
advisory or administrative fees for certain periods since the inception date. In
such cases, and without the waiver of fees, total return would have been lower.

     The Institutional Shares of the Japan Fund are distributed by the Barr
Rosenberg Series Trust. Select Shares are distributed by Barr Rosenberg Funds
Distributor, Inc.

     The global equity markets went through a strong but volatile year. On the
one hand, consumer confidence remained high and investors' enthusiasm for
technology stocks continued to climb. This provided a rejuvenating force for the
equity markets. On the other hand, worries about an overheated economy led to
fears over further increases in interest rates. This, together with the anxiety
over Y2K, cast a shadow over global stocks. Overall, most markets posted
impressive gains for the year ending March 31, 2000. International small stocks,
as measured by the Cazenove Rosenberg Global Smaller Companies Index excluding
the U.S. (CRIexUS)(1), posted a long-awaited rebound by returning over 21%. The
Salomon Smith Barney World ex U.S. Extended Markets Index, another notable
benchmark for international mid/small stocks, gained 24%. 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), were also up 25%.

     After enjoying spectacular growth in 1997 and 1998, the European markets
underperformed other developed markets in 1999. Since its inception, the euro
depreciated close to 23% against the U.S. Dollar. The weakness of the euro,
together with the associated concerns over the success of Euroland, dampened the
European stock markets in the first part of 1999. On the positive side, since
July, corporate restructurings and merger and acquisition activities have
proceeded at a record pace. The numerous high-profile cross-border transactions
helped to buoy investors' interests in the European markets. For the year ending
March 31, 2000, European small stocks gained close to 17%(2), while large stocks
returned 19%(2). From October 1999 through February 2000, technology related
"new economy" growth stocks reigned over the market. However, the trend reversed
in March when the market refocused on the more traditional value-based companies
e.g. those in banking and retail/wholesale. Investors' confidence remained
strong and domestic consumption was still robust. In spite of the formation of
Euroland, market performance across Europe diverged rather than converged over
the past 12 months. While small company stocks in Norway and Sweden posted
strong double-digit returns, the performance of small stocks in Belgium and
Spain were in negative territory.

     After to close to 10 years of malaise, Japan re-emerged as one of the best
performing markets last year. Japanese small stocks delivered gains of over
35%(2), and large company stocks returned in excess of 45%(2) over this period.
Part of the gains came from the appreciation of the yen, which gained 15%
against the U.S. dollar during the past 12 months. The resurgence of the
Japanese market was a direct result of renewed interest and buying from overseas
investors. With the high domestic savings rate and the low yield from
traditional bank deposits, it was expected that Japanese locals would eventually
re-enter the equity market. Much of the growth in the market was in anticipation
of this cash injection. Domestic investors, on the other hand, have thus far
remained cautious. Meanwhile, the Japanese government has made a conscious
effort to revitalize the economy. For example, the abolishment of securities
transaction taxes, allowing companies to reorganize, and the promotion of
greater accounting transparency were all positive measures that contributed to
the growth of the economy. Similar to the U.S. and Europe, technology and
Internet-related growth stocks

                                       19

were extraordinarily strong since fourth quarter 1999. However, after close to
six months of extreme enthusiasm toward Internet companies, investors, domestic
and foreign alike, opted to return to Japanese value stocks in March 2000.

     Elsewhere in Asia, the various countries are now on a solid path of
recovery. Real estate prices have stabilized, and domestic consumption has also
picked up. Strong demand from U.S. and Europe is also helping to boost Asian
exports and hence industrial activities. Similar to the rest of the world,
numerous start-up companies focusing on technology and Internet-related
businesses have sprung up. The various Asian countries are still highly
susceptible to the U.S. interest rate policy and the political situations within
the region. For example, in the first quarter of 2000, markets posted losses
throughout as a result of fears of a U.S. interest rate hike and the political
worries surrounding the presidential election in Taiwan. Overall, for the year
ending March 31, 2000, small company stocks reaped 36%(2), surpassing the 24%(2)
gains from large stocks.

     Canadians have been enjoying one of the healthiest economies in history. A
sound budget led to the long-awaited tax cuts in Ontario. This was welcomed by
businesses and consumers alike and helped to boost already-strong domestic
spending and investors' confidence. Expanding beyond the metals and commodities
industries, Canadian companies are increasingly active in the field of
telecommunications and network equipment. This helped to propel the Canadian
market last year. Thanks to the frenzy in telecommunications related stocks,
large stocks delivered over 68%(2) while small stocks gained over 27%(2).

     Most European currencies lost ground against the U.S. dollar over the past
12 months, with the euro depreciating over 11% and the British pound losing a
slight 1%. The Canadian dollar had strengthened over 4%, thanks to a rebound in
world commodity prices. Of all the currencies of the developed markets, the
Japanese yen appreciated the most against the U.S. dollar. During the past 12
months, the yen gained over 15%.

     For the year ending March 31, 2000, the Fund outperformed its benchmark,
the Cazenove Rosenberg Global Smaller Companies Index excluding the U.S.(1) The
outperformance was a combination of stock selection and risk management. The
portfolio had a slight value bias, which hurt performance during the fourth
quarter of 1999, but on average, helped over the whole year. The Manager strives
to add value consistently through bottom-up stock selection and avoids heavy
bets on countries and industries. The portfolio closely tracks the country and
industry exposures of the benchmark. As a result, the contributions to the
outperformance from industry and country selection were positive but modest,
whereas stock selection accounted for most of the outperformance. In particular,
the Manager's stock selection models worked well in Europe. Since inception, the
Fund's performance has also exceeded that of the benchmark.

     The Manager follows a systematic and disciplined approach to international
investing. The portfolio holdings are diversified over 21 countries and 300
companies. As of March 31, 2000, the top 10 holdings accounted for about 23% of
the total portfolio. Approximately 68% of the holdings were invested in Europe.
Financial companies and those engaged in electronic components together
represented over 20% of the portfolio. The price-to-positive-earnings ratio of
the portfolio was about 13, and the median market capitalization of the holdings
was approximately $300 million.

     Performance data represents past performance which does not guarantee
future results. Investment return and principal value may increase or decrease
depending upon market, economic, political, currency exchange rates and other
conditions affecting a fund's portfolio, so that an investor's shares, when
redeemed, may be worth more or less than their original cost.

     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.

     Total return includes change in share price and reinvestment of
distributions. Total return set forth may reflect the waiver of a portion of the
Fund's advisory or administrative fees for certain periods since the inception
date. In such instances, and without the waiver of fees, total return would have
been lower.

     For the year ended March 31, 2000, the broad market barometer as measured
by the Russell 3000(1) climbed 22.28%. Mid-small growth stocks were the best
performers for the year, surging 80.94% while large cap value stocks were the
worst, gaining only 6.34%. The overall picture, however, masks a volatile
market. Throughout the year, worries about interest rates hikes, smooth Y2K
transitions, oil price increases and rising inflationary pressures constantly
caused stock market jitters. Not all industries participated in the rally
equally. The biggest winner was the technology industry, especially the small
cap technology stocks.

     Investors continued to show enthusiasm for stocks with high price momentum,
high price/earnings and high trading activity, which translated into huge gains
for growth across all capitalization sectors. Over the trailing 18-month period,
for example, the Russell 2500 Growth Index(2) outperformed the Russell 2500
Value Index(3) by more than 100%.

     Looking at performance along the capitalization dimension, small stocks
gained almost twice as much as large stocks over the trailing year. The Russell
2000 returned 37.29%(4), while the Russell 1000 returned 21.19%(5), and the S&P
500 gained 17.94%(6). Much of small cap's success related to the sizzling
performance of technology-related, small growth stocks (particularly in
February, 2000).

     The year ending March 31, 2000 was extremely difficult for the Fund. The
Fund underperformed its benchmark, U.S. 90-day Treasury Bills, by more than
- -19%.

     The Manager's stock selection models produce long and short portfolios with
a consistent net exposure to value characteristics, as well as a bias toward
companies whose stock is less frequently traded. When the long portfolio is
compared to the short portfolio, it is possible to gauge approximately how much
was gained and lost due to the net portfolio characteristics. The two largest
risk exposures reflect the value bias in the net portfolio: positive exposure to
earnings/price and book/price. The negative exposure to trading activity
indicates the net portfolio's moderate dislike of stocks that are frequently
traded. Of particular significance over the last year (especially the first
quarter of 2000) was the positive exposure to relative strength, a measure of
price momentum.

     Exposure to common risk factors contributed -5.18% to the Fund's
underperformance. The positive exposures to earnings/price and yield, -2.89% and
- -1.97% respectively, negatively impacted performance. In comparison, the bias
toward stocks whose performance is momentum driven made the most significant
positive contribution to return because of the very large contribution of
relative strength (+6.75%). The exposure to trading activity (-3.78%) worked to
further dampen performance for the same reason.

     The bulk of the Fund's underperformance is unexplained by common risk
factor exposures. The most significant factor was stock selection. Reviewing the
types of stocks that were rewarded (and the types that were punished) over the
last year gives insight into why the contribution attributable to stock
selection was so negative. Fundamental to the

                                       30
<PAGE>   31

Manager's stock selection process is the belief that a portfolio with a net
earnings advantage will be rewarded. Though the stocks that the Manager bought
long did consistently produce more future earnings per dollar of cost than the
stocks sold short, the market did not reward earnings. In fact, at certain times
over the year, the market seemed to be actively penalizing stocks with good
long-term earnings prospects in favor of those with no earnings or negative
earnings. In sum, the Manager's stock selection process will suffer when
investors are not interested in reconciling current prices with future earnings
or other fundamental measures of value.

     Performance data represents past performance which does not guarantee
future results. Investment return and principal value may increase or decrease
depending upon market conditions so that an investor's shares, when redeemed,
may be worth more or less than their original cost.

     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 no bear the risk of losing their investment. The income received
from T-bills is free from state income tax.

     Total return includes change in share price and reinvestment of
distributions. Total return set forth may reflect the waiver of a portion of the
Fund's advisory or administrative fees for certain periods since the inception
date. In such instances, and without the waiver of fees, total return would have
been lower.

     The Institutional Shares of the Barr Rosenberg Market Neutral Fund are
distributed by the Barr Rosenberg Series Trust. The Investor Shares are
distributed by Barr Rosenberg Funds Distributor, Inc.

     The Fund underperformed the S&P 500 Index(1) for the year ended March 31,
2000, by more than -20.5%. This Fund holds S&P 500 Index Futures contracts and
shares in the Market Neutral Fund. The Institutional shares of the Market
Neutral Fund returned -14.13% for year. (See separate commentary for the Market
Neutral Fund.) Investment in S&P 500 Futures also contributed negatively to
performance during the year by slightly more than -6%.

     Performance data represents past performance which does not guarantee
future results. Investment return and principal value may increase or decrease
depending upon market conditions so that an investor's shares, when redeemed,
may be worth more or less than their original cost.

     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 a particular contract at any particular
time.

     Total return includes change in share price and reinvestment of
distributions. Total return set forth may reflect the waiver of a portion of the
Fund's advisory or administrative fees for certain periods since the inception
date. In such instances, and without the waiver of fees, total return would have
been lower.

     The Institutional Shares of the Barr Rosenberg Double Alpha Market Fund are
distributed by the Barr Rosenberg Series Trust. The Investor Shares are
distributed by Barr Rosenberg Funds Distributor, Inc.

</TABLE>

     For the year ended March 31, 2000, the S&P 500 Index(1) gained 17.94%, the
broad market Russell 3000 Index(2) returned 22.28% and the small cap barometer
Russell 2000 Index(3) surged 37.29%. The year saw a much wider gulf between the
fortunes of value and growth stocks. The large cap Russell 1000 Value Index(4)
returned 6.34% while the Russell 1000 Growth Index(5) added 34.12%. The U.S.
market rally has been narrowly focused on growth stocks with high price
momentum, high price/earnings and high trading activity. The returns for the
year were more volatile than other time periods. Market jitters were primarily
caused by concerns over rising interest rates, fears about Y2K transition and
pressures over increasing oil prices throughout the year.

     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, which has modest sector over and under weights, the Select
Sectors Market Neutral Fund will typically have larger exposures to different
business sectors and industries based on quantitative bottom-up company
analysis.

     For the year ended on March 31, 2000, the Fund outperformed its benchmark,
U.S. 90-day Treasury Bills, by more than 4%. In addition to the positive
contributions from the exposures to relative strength (measure of trailing
12-month price performance) (+4.99%) and to trading activity (measure of
trailing 12-month share turnover) (+3.17%) during this period, the Fund
benefited from long industry exposures to office machinery (+2.87%), services
(+1.96%) and electric utilities (+1.49%). Short industry exposures to drugs
(-2.59%), paper (-0.77%) and media (-0.67%) contributed negatively to
performance. Stock selection further dampened performance (-4.72%).

     Performance data represents past performance which does not guarantee
future results. Investment return and principal value may increase or decrease
depending upon market conditions so that an investor's shares, when redeemed,
may be worth more or less than their original cost.

     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

                                       45
<PAGE>   46

full faith and credit of the U.S. Government. T-bills have a fixed rate of
return, and investors do no bear the risk of losing their investment. The income
received from T-bills is free from state income tax.

     Total return includes change in share price and reinvestment of
distributions. Total return set forth may reflect the waiver of a portion of the
Fund's advisory or administrative fees for certain periods since the inception
date. In such instances, and without the waiver of fees, total return would have
been lower.

     The Institutional Shares of the Barr Rosenberg Select Sectors Market
Neutral Fund are distributed by the Barr Rosenberg Series Trust. The Investor
Shares are distributed by Barr Rosenberg Funds Distributor, Inc.

BARR ROSENBERG SERIES TRUST
NOTES TO FINANCIAL STATEMENTS
MARCH 31, 2000
- --------------------------------------------------------------------------------

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 and Select
Sectors Market Neutral Fund, 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 Select Sectors Market
Neutral Fund are authorized to issue Investor Shares. The classes differ
primarily with respect to the level of Service Fees and Distribution Fees and
Shareholder Service 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 U.S. Small Capitalization Series was reopened to all investors effective
March 27, 2000.

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 or persons acting at their
discretion.

  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.

  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 contracts involves, to varying degrees, elements of market
risk. Risks arise from 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,
2000, the values of securities sold short in the Market Neutral Fund and the
Select Sectors Market Neutral Fund amounted to $77,232,165

and $25,778,286, against which collateral of $154,037,366 and $53,437,638 was
held, respectively. The collateral includes the Bear Stearns Deposit Account 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, 2000, the value of securities loaned amounted to $0 against which
cash collateral of $192,500 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 and Shareholder Service expenses are solely borne by and
charged to the Select Shares and Investor Shares; Service fees are charged to
the Adviser 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.

3. MANAGEMENT, ADMINISTRATION, FUND ACCOUNTING, DISTRIBUTION AND SHAREHOLDER
SERVICES AGREEMENTS. AXA Rosenberg Investment Management LLC (the "Manager")
provides advisory and management services to the Funds under separate management

the U.S. Small Capitalization Series, 1.50% of the average net assets of the
Japan Series and International Small Capitalization Series, and 2.35% of the
average net assets of the Double Alpha Market Fund (2.00% of which reflects the
expense ratio of the Market Neutral Fund, which the Double Alpha Market Fund
invests in). This includes the management fee but excludes the Service fees, and
the Distribution and Shareholder Service fees. The Manager has agreed to
maintain an operating expense ratio for the Market Neutral Fund of 2.00% and for
the Select Sectors Market Neutral Fund of 1.25% of each Fund's average net
assets, exclusive of the dividend expense on short sales. The operating expense

Administrator has agreed to waive all fees in the Japan Series and the Double
Alpha Market Fund until the net assets reach $25 million. For the year ended
March 31, 2000, the amount of such waivers totaled $265,333, $2,123, $23,128,
$66,947, $11,523 and $28,083 for the U.S. Small Capitalization Series, Japan
Series, International Small Capitalization Series, Market Neutral Fund, Double
Alpha Market Fund and the Select Sectors Market Neutral Fund, respectively.

BISYS serves the Trust as fund accountant. Under the terms of the fund
accounting agreement, BISYS is entitled to receive an annual fee of $30,000 for
the U.S. Small Capitalization Series, Japan Series and International Small
Capitalization Series, $50,000 for the Market Neutral Fund, Double Alpha Market
Fund and the Select Sectors Market Neutral Fund, and is reimbursed for certain
out-of-pocket expenses incurred in providing fund accounting services.

The Trust has adopted a Distribution and Shareholder Service Plan for its Select
Shares and Investor Shares, pursuant to Rule 12b-1 under the 1940 Act. The
Select Shares and Investor Shares of the Funds are sold on a continuous basis by
the Trust's Distributor, Barr Rosenberg Funds Distributor, Inc. (the
"Distributor"), an indirect wholly owned subsidiary of The BISYS Group, Inc.
Under the Distribution and Shareholder Service Plan, the Funds pay the
Distributor for expenses primarily intended to result in the sale of the Select
Shares and Investor Shares. The Select Shares and Investor Shares are subject to
an annual Distribution and Shareholder Service Fee of up to 0.25% of the
respective average daily net assets. For the year ended March 31, 2000, the U.S.
Small Capitalization Series, Japan Series, International Small Capitalization
Series, Market Neutral Fund, Double Alpha Market Fund and the Select Sectors
Market Neutral Fund incurred distribution and shareholder service expenses in
the amount of $34,400, $266, $4,504, $38,217, $290 and $2,469, respectively. Due
to the closing of the U.S. Small Capitalization Series, the distributor has
agreed to waive distribution and shareholder service expenses in connection with
shares that were directly purchased prior to the closing of the fund. For the
year ended March 31, 2000, the amount of the waiver was $19,543. In addition,
the Trustees have authorized each Fund to pay up to 0.15% of its average daily
net assets attributable to Select Shares and Investor Shares for sub-transfer
and sub-accounting services in connection with such shares.

Various service organizations act as servicing agents of the Adviser Shares of
the U.S. Small Capitalization Series. Such shares are subject to an annual
Service Fee of up to 0.25% of the average daily net assets attributable to such
shares in accordance with a Service Plan adopted by the Trust. For the year
ended March 31, 2000, the Service Fee attributable to the Adviser Shares was
charged as incurred, and amounted to 0.16%.

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, 2000, the Japan Series had a capital loss carryover of $578,234
of which $13,801, $20,835, $261,584, and $282,014 will expire on March 31 of the
years 2002, 2004, 2006 and 2007, respectively. The Market Neutral Fund had a
capital loss carryover of $48,444,104, of which $20,880,748 and $27,563,356 will
expire on March 31 of the years 2007 and 2008, respectively. The Double Alpha
Market Fund had a capital loss carryover of $60,949, which will expire on March
31, 2008. The Select Sectors Market Neutral Fund had a capital loss carryover of
$2,186,540, which will expire on March 31, 2008. 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.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Trustees and Shareholders of Barr Rosenberg Series Trust,

     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 the Barr
Rosenberg Series Trust (the "Trust") at March 31, 2000, 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 accounting principles
generally accepted in the United States. 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 auditing standards
generally accepted in the United States 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,
2000 by correspondence with the custodian and brokers, provide a reasonable
basis of the opinion expressed above.
