                     BOSTON PARTNERS FAMILY OF MUTUAL FUNDS
                           PORTFOLIO MANAGER'S LETTER



February 28, 1999

Dear Shareholder:

     1998 and the first two  months of 1999  have  provided  very  disappointing
investment  results  for  value  managers  and  Boston  Partners  shared in this
disappointment. In order to communicate some of the issues behind these results,
we  thought  it  best  to  make a list  of  questions  we  have  been  asked  by
shareholders, consultants, and ourselves concerning performance.

     We hope that these  questions  and answers will serve as an initial step in
the discussions about recent performance in your portfolio,  the expectations we
have for the  future,  and why we feel  confident  in our  ability to meet these
expectations.

"WHY  DID  VALUE  MANAGERS  UNDERPERFORM  THE S&P 500  INDEX  OVER  THE LAST SIX
MONTHS?"

     The S&P 500 Index ("S&P 500")  continues to be heavily  influenced by large
cap growth  stocks and as such,  the index was a very  difficult  benchmark  for
value  managers to beat.  Similar to a period in the early 1970's,  value stocks
severely lagged as investors chose to invest in the perceived safety of mega-cap
growth stocks whose  earnings  were growing at a premium to the market.  Because
these mega-cap growth stocks were such a large percentage of the S&P 500 in 1998
and continue to be in 1999,  they  influenced  its return more than at any other
time in  history.  The  persistent  underperformance  of the  value  style and a
narrowness of performance in a small number of mega-sized companies created both
a growth style and capitalization bias.

"WHAT DO YOU MEAN BY NARROWNESS OF THE MARKET PERFORMANCE?"

     Narrowness  refers to the small number of companies  that led the market in
its 1998 and 1999 advance. Of all the companies in the Russell 1000 Value Index,
the 20 largest  contributors  accounted for 73% of the return. Over the previous
three years, this figure averaged 35%. Also indicative of the lack of breadth in
the large cap value  universe  is the median  return of the  Russell  1000 Value
Index of 2.32%. In the broader market,  the return of the average NYSE stock was
negative 6%.

"COULD YOU BE MORE SPECIFIC, AND GIVE SOME DETAIL?"

     We estimate that a value style,  defined as low Price to Earnings (P/E) and
low Price to Book (P/B),  accounted for approximately  one-half of our shortfall
vs. the S&P 500 (measured  simply by the difference  between the S&P 500 and the
Russell   1000  Value   Index).   The   difference   between  our  lower  market
capitalization  and  that  of the  relevant  indexes  contributed  approximately
one-quarter of the shortfall.  Finally,  poor stock selection contributed to the
remaining quarter.

"COULD YOU BE SPECIFIC ABOUT SOME OF THE PROBLEMS OF STOCK SELECTION IN 1998 AND
EARLY 1999?"

     Throughout 1998 and into 1999,  companies with positive  business  momentum
were selling at historically  high levels.  In our research process we were able
to identify companies that were undergoing changes which we thought would create
business momentum. Most of the companies we uncovered were undertaking corporate
restructurings  as a  way  to  create  this  business  momentum  and  strengthen
earnings.  Since some of the  restructurings  were taking  place in  commodities
businesses,  the low level of inflation  and lack of  purchasing  power made the
success of the  restructurings  only marginal at best. Other companies,  such as
Venator  (Woolworth),  never  achieved  success.  Another  example of poor stock
selection that affected our performance this year was Northrop Grumman. Northrop
Grumman was on track to merge with  Lockheed  Martin during the first quarter of
'98, a merger that would have been  accretive to earnings.  However,  anti-trust
concerns in the 11th hour of the merger  caused the deal to fall apart,  and the
stock tumbled. A significant  position at the time,  Northrop Grumman was one of
the biggest detractors of the year.

"WHY DO YOU BELIEVE  GROWTH AND SIZE DID SO  EXTRAORDINARILY  WELL OVER THE PAST
SIX MONTHS?"

     Experience  has shown that it is always  easier to explain the past than it
is to forecast the future. In looking back over the last six months, many of the
companies  that performed well had excellent  brandname  recognition  around the
world, were very liquid stocks, and, in general, had good financial profiles. In
times of economic  uncertainty many investors choose to pay substantial premiums
for  these  characteristics.  With  political  problems  here in the  U.S.,  and
economic  problems in Asia, the emerging markets,  and much of Europe,  1998 and
early 1999 were clearly a period of uncertainty.  With a move to indexing, money
flowing into these stocks has also increased, further lifting their prices.

"WHY DID YOU UNDERPERFORM YOUR COMPETITORS?"

     Although  it is  impossible  to know  with  certainty  how our  competitors
structured  their  portfolios  in 1998,  we believe that the primary  reason for
underperformance  was our  unwillingness to stray from our value  discipline.  A
preliminary year-end comparison versus other value managers shows our portfolios
to have stronger value  characteristics,  i.e.,  lower average  weighted  P/E's,
P/B's and Price to Sales. This adherence to value,  coupled with a lower average
weighted  market  capitalization  was  a  significant  reason  for  lagging  the
competition. We believe that the same reason should provide a recipe for success
when the events of 1998 and early 1999 return to some normalcy.

"HAVE YOU CHANGED ANYTHING ABOUT YOUR INVESTMENT PROCESS IN THE LAST YEAR?"

     We have not changed course either in our value orientation, our emphasis on
fundamental  analysis,  or our belief in the  benefits  of  diversification.  We
continue to believe  that the  fundamental  premises  upon which our  investment
philosophy  has been  built  remain  sound.  It is a  regular  routine  of ours,
however, to review the process by which we execute this philosophy, irrespective
of near term performance.

     Given the heightened  volatility of the markets as well as the dramatically
changed complexion of our benchmarks, we have increased the frequency with which
we review the risk profile of our large  capitalization  equity  product  versus
both the S&P 500 and the Russell 1000 Value Indexes. On a weekly basis we review
the sources of risk  relative  to both  indexes not only from a sector and stock
specific  over/underweight  position,  but also  with  respect  to  non-industry
factors such as Beta, capitalization,  earnings volatility, etc. Included in our
analysis  is   performance   attribution   of  our  portfolios  by  both  market
capitalization and price/earnings deciles.

     In terms of personnel,  we hired two new  fundamental  analysts  within the
last  twelve  months  and will  likely  hire  two  more in 1999.  We have had no
departures of investment professionals since our inception.

"WHAT ABOUT THE FUTURE?  WHY WON'T THE THINGS YOU HAVE OUTLINED CONTINUE IN 1999
AS THEY DID IN 1998?"

     We would like to answer this in three parts.  First, it is always difficult
to predict when  particular  styles of investing will shift in and out of favor.
We do believe, however, that value investing is a winning strategy over the long
term. Therefore, while it is certainly possible that 1999 may be a year in which
growth again beats value,  we are firmly  committed to our  discipline of buying
what we believe are undervalued securities with prospects for appreciation.

     Second,   while  it  is  difficult  to  time  the  performance  of  various
capitalization  segments,  it is our opinion  that today there exists the widest
dispersion  in the past thirty  years  between the largest 20% of the market and
the remaining 80%. We believe this valuation spread to be unsustainable over the
long term. This would mean that value exists not in the mega-cap companies,  but
in the large to mid-cap companies.

     Third,  in  regards  to  stock  selection,  we will  continue  to  employ a
disciplined  sell  process  whereby  we exit  securities  that we  believe to be
overvalued.  While this  strategy  worked  against us in 1998 (Merck,  Wal-Mart,
Bristol-Myers),  we think it could be  dangerous  and  imprudent  to assume that
expensive  stocks will  continue to  appreciate.  As we  re-deploy  capital from
overvalued  securities we will be disciplined in our assessments of the catalyst
required  to  unlock  intrinsic  value.  Moreover,  in the  face of an  activist
Administration, we increasingly weigh the potential impact to our portfolio from
political/regulatory risks, e.g., Northrop Grumman.

                                        2

"IS VALUE INVESTING ALIVE AND WELL?"

     Absolutely.  The  reason  we  believe  value  investing  produces  superior
long-run returns is complex and not easily explained in a few sentences.  But at
its core is the notion that a value  strategy  takes  advantage of what has been
termed the "status-quo bias" of investors. This refers to investors' tendency to
look at a company's recent financial and share price trends and extrapolate them
far into the future.  In so doing,  they overpay for strong  current  trends and
underpay for recent  disappointments.  History has shown,  however,  that only a
relatively small percentage of stocks can sustain high growth rates in sales and
earnings  for long periods of time and the penalty  inflicted on "fallen  growth
stocks" is typically  severe.  In the  meantime,  the  managements  of companies
producing less than acceptable returns are under intense pressure to "fix" their
problems or find  themselves  out of a job.  As these  problems  are  addressed,
investor confidence is restored and share price performance improves.

     We think this status-quo bias was taken to unprecedented  extremes over the
past  six  months.  In the  face of a  slowing  profit  growth  environment  and
lingering concerns about Asian and Latin American  economies,  investors flocked
in droves to the perceived  security of the  mega-capitalization  growth stocks,
driving them to  valuation  levels that are in most cases well beyond even those
seen in the "Nifty-Fifty" era of the early 1970's.

     Some  believe  that value  investing  has no future,  and that these richly
valued growth stocks can  universally  sustain  double-digit  sales and earnings
growth well into the next decade and that the  interest  rate  environment  will
remain benign for years to come. We're skeptical of this scenario.

     Some of the market's  darlings of 1998 may  navigate  their way through the
uncertain  times ahead and continue to reward their  shareholders,  but many may
disappoint as well. Given what we believe to be their lofty current  valuations,
their fall from grace is apt to be very painful for investors.  We believe it is
far more prudent to invest in those  companies that are in our opinion  sensibly
priced,  possess a strong business  franchise and are taking the necessary steps
to enhance their earnings potential.

     In summary,  not only do we believe that value investing is alive and well,
we believe that its  exceptionally  poor relative  performance in 1998 and early
1999 could nonetheless set the stage for a very rewarding period ahead.

WHAT ABOUT THE MID CAP VALUE FUND AND THE MICRO CAP VALUE FUND?

     Mid cap stocks have  excelled  in the last six months as the  Russell  2500
Index moved up 17.27% for the period.  When The Federal  Reserve eased  interest
rates on October  15th,  the added  liquidity  precipitated  by the cut  brought
investors back into the smaller end of the market where  tremendous  value could
be found.  The last six months  has also  brought a change of  investment  style
preference in the mid cap arena. In the fourth quarter and into 1999, the growth
investment style surpassed value, which had been winning in previous quarters.

     There were no major  changes to the  portfolio  composition  of the Mid Cap
Value  Fund.  There  were  slight  increases  in  Capital  Goods,   Energy,  and
Technology.  Consumer  Durables and  Healthcare  decreased.  As Boston  Partners
follows a bottom up  investment  process,  sector  weightings  are  regulated by
internal  guidelines,  which insure that the portfolio is diversified.  However,
sector weightings are not dictated by top-down analysis, as we do not attempt to
predict the market's  movements.  Sector weights fluctuated as a residual of our
individual  stock  selection  process.  The portfolio's  strongest  sectors were
Capital  Goods,   Consumer  Durables,   Consumer  Services,   Health  Care,  and
Technology.  Energy and Utilities, strong sectors during the third quarter, were
weaker  during the fourth  quarter.  Considerable  gains came from the following
holdings:

     BJ'S  WHOLESALE CLUB ("BJ's") was a strong  contributor  for the six months
ending  February 28, 1999. The company is the nation's third largest  membership
warehouse  club  selling  food  goods  (60%  of  sales),   as  well  as  general
merchandise.  BJ's  continues to sell at a deep  discount on a price to earnings
basis  to its  competitors.  We  feel  this  discount  is not  justified  by the
fundamentals. BJ's continues to expand its store base at a 10% annual rate, with
10 new stores currently planned in 1999. BJ's is less cyclically  exposed,  with
65% of all sales  coming from food  merchandise,  which could bode well for them
should the US economy slow in 1999.  Finally,  management  continues to use free
cash to buy back stock which is accretive to earning.

     In Health Care, IVAX CORPORATION proved to be a strong holding in the fund.
Ivax   Corporation  is  a   pharmaceutical   company   specializing  in  generic
pharmaceuticals,  respiratory,  and oncology. The company's proprietary products
include Paxene, a cancer treatment,  and the Easi-Breathe  inhaler. The company,
which  once  included  a  chemicals   business,   now  concentrates   solely  on
pharmaceuticals.

     Detractors from the portfolio's  performance  include PITTSTON BRINKS GROUP
in the Capital Goods sector. The company provides armored car services, currency
and  deposit  processing,  ATM  servicing  and air courier  services  worldwide.
Additionally,  Brinks Home Security installs,  maintains and monitors electronic
home security systems in the US and Canada.  Although the company's  returns for
the period were negative,  we believe that the company is strong  fundamentally,
sells at a discount to its peers, and has strong organic growth.

MICRO CAP VALUE FUND

     The micro cap stocks that were  struggling  alongside the small and mid cap
securities  for much of the last six months  continue to  struggle.  The Federal
Reserve's  easing of interest rates in October  created added  liquidity,  which
flowed  into  the  smaller   capitalization  stocks  that  had  been  previously
neglected,  but  their  advances  have  been  short-lived.   As  in  the  larger
capitalizations,  the stocks that prompted the most interest were the technology
growth stocks.  As measured by the Russell 2000 Value Index and the Russell 2000
Growth  Index,   the  smaller   capitalizations   reversed  their  prior  trend;
growth-style  investing  beat  value-style  investing in the fourth  quarter and
continues so far in 1999. The Russell 2000 Growth Index returned  29.28% for the
quarter,  while the Russell 2000 Value Index  returned  4.93%,  a difference  of
2,435 basis points. The CRSP 9-10, our micro cap benchmark,  returned 17.80% for
the six month period.

     The Boston  Partners Micro Cap Value Fund was  overweighted  in the Finance
and Consumer  Services sector as compared with the CRSP 9-10 Index. The fund was
underweighted  in Health Care and  Technology,  as there was less value in these
sectors.  The Health Care and Technology Sectors,  which combined totaled 33.03%
of the CRSP 9-10 Index, were very strong contributors to the benchmark's return.
The technology sector in particular,  returning 32.61% (CRSP 9-10 Index) for the
quarter,  illustrates  what we believe to be the large gap in valuation  between
the  growth  technology  stocks,  and the  overall  micro cap  environment.  Our
underweighting in these growth-driven sectors hurt our performance in comparison
to the benchmark. One of the fund's greatest weightings,  Finance, returned well
above the  benchmark's  Finance return with a 430 basis points  difference.  The
fund's returns in the Transportation,  Consumer Durables, Energy, Capital Goods,
Basics and Utilities were also above the benchmark's returns for these sectors.

     The fund  continues to closely  follow  Boston  Partners'  value  investing
process that selects  companies  believed to be  undervalued  with good business
fundamentals and a catalyst for change. A previous  contributor to the portfolio
includes Group 1 Automotive.

     Group 1 Automotive,  a company the fund has held since  inception,  was the
second greatest contributor for the quarter. Group 1 Automotive,  a consolidator
of car dealership businesses, currently owns over 60 dealerships in 6 states. We
think  the  company  has  strong  fundamentals  and  continues  to grow  through
acquisitions of large dealer groups.  The company,  which went public in October
of 1997, was initially hit hard by the market,  but now seems to have gained its
footing.  With a positive earnings surprise in October of 1998, analysts at that
time put a "buy" recommendation on the stock. The stock reached our target price
and was  sold.

Micro  Cap  Companies,  as  defined  by our  product,  are  those  with a market
capitalization  of less than $500 million.  These  companies  tend to be new, in
early development,  or in transition.  Usually, micro caps are rapidly evolving,
generating  a new  product or  service,  or taking  advantage  of a new  market.
However,  returns  may  be  inconsistent  and  may  fluctuate  widely  over  the
short-term,  and small  stock  valuations  tend to be more  sensitive  to market
psychology.  As a result,  an investment in Boston Partners Micro Cap Value Fund

YOU JUST STARTED THE BOSTON PARTNERS MARKET NEUTRAL FUND. HOW HAS IT PERFORMED?

     Our Market  Neutral  Fund started  November  17, 1998,  in the wake of this
volatile  market  that  hasn't  been  kind to value  managers.  The fund aims to
produce 15%  annualized  returns  over a four year market cycle  independent  of
market direction.  In order to achieve this goal in a market neutral fashion, we
attempt to  minimize  the  portfolio's  beta  (market  sensitivity.)  We do not,
however, neutralize all sources of portfolio risk. This last point was painfully
evident  during  our first  three and one half  months  of  operation.  While we
believe that the market  neutral  product is a relatively  low risk  approach to
investing,  we do not believe that market  neutral  portfolio  structures  offer
returns for no risk. There is no free lunch in market neutral investing any more
than there is in long-only  investing.  One of the primary  advantages we see of
market neutral  investing is that it allows the managers to target which sources
of  return  (and  risk)  they  wish  to  employ.  Like  all of  Boston  Partners
portfolios,  the market  neutral  portfolio is based on a value  philosophy  and
process.

     Our Market  Neutral Fund invests in stocks that we believe are  undervalued
with sound business  fundamentals and positive business  momentum.  We will sell
short  stocks  that  we  think  are  overvalued  with   deteriorating   business
fundamentals  and  declining  business  trends.  In the first three and one half
months,  technology stocks (more specifically internet stocks) that we felt were
overvalued with no strong balance sheets or earnings  continued to perform well.
While we do not know when this phenomena  will change,  we do believe that these
companies'  prices cannot continue to grow. At some point in time,we expect that
fundamentals  will become important again.  Assuming this happens,  this is when
the Boston Partners Market Neutral Fund could excel.

HOW DID THE BOSTON PARTNERS BOND FUND PERFORM?

     Following a tumultuous  third  quarter,  the bond market calmed down during
the fourth quarter. The Federal Reserve eased monetary policy 25 basis points on
September  29th,  amid overseas  turmoil and distress among certain hedge funds,
banks, and broker-dealers.  They eased again in both October and November, at 25
basis points each time. The  encouragement of lower short term interest rates, a
subsequent  rally in the stock market to new highs,  and data indicating  robust
3%-4% GDP  growth in the  quarter  all helped  alleviate  investor  fears.  As a
result,  the flight to quality that  benefited  Treasuries  in the third quarter
reversed somewhat in the fourth quarter.

     Treasury rates rose 13-32 basis points  depending on maturity with 1-5 year
rates yielding 4.5% and the thirty year bond at 5.1%. In the  government  sector
these higher rates erased coupon income for the quarter.  However, the corporate
and mortgage sectors performed better,  lifting the broad Lehman Aggregate Index
to a .34% return for the period.

     Inflation  for 1998 was about 1.6% and may rise  somewhat  in 1999,  but we
expect it to remain  relatively low.  Corporates and mortgages  recovered during
the quarter,  but their relative  risk-adjusted  performance  still lags for the
year.

     During the first two months of 1999, the main theme was the recovery of all
spread sectors. All non-Treasury sectors posted impressive excess returns during
the period.  This occurred  during a period of rising  interest  rates,  most of
which occurred in February. At that time, the Lehman U. S. Treasury Index posted
its worst one  month  performance  since  December  1981 with a total  return of
- -2.55%.  Much of this can be attributed to Federal Reserve Chairman  Greenspan's
comments  questioning  recent  interest rate cuts in the face of recent economic
strength.

     The  rebound in  corporates,  mortgages,  and high  yield was  substantial,
driven by renewed  liquidity in the markets and decreased  volatility  after the
tumultuous last half of 1998. Year to date 1999, U. S. Treasuries  posted a loss
of 1.99%.  Investment  grade  corporates,  mortgages,  and high  yield  returned
- -1.41%,  0.31% and 0.89% respectively.  We continue to overweight spread product
based upon what we believe to be superior long term return potential.

 *  Commencement of operations.

**  Calculated  based on  shares  outstanding  on the  first and last day of the
    respective  periods,  except for dividends and distributions,  if any, which
    are based on actual shares outstanding on the dates of distributions.

(1) Reflects waivers and reimbursements.

(2) The amount  shown for a share  outstanding  throughout  the period is not in
    accord  with the change in the  aggregate  gains and  losses in  investments
    during the period because the timing of sales and repurchases of Fund shares
    in relation to fluctuating net asset value during the period.

(3) Total return iscalculated assuming a purchase of shares on the first day and
    a sale of shares on the last day of each period  reported  and will  include
    reinvestments  of dividends and  distributions,  if any. Total return is not
    annualized.

(4) Without the waiver of advisory,  administration  and transfer agent fees and
    without  the  reimbursement  of  certain  operating  expenses,  the ratio of
    expenses to average net assets annualized for the periods ended February 28,
    1999,  August 31, 1998 and August 31, 1997 would have been 1.28%,  1.49% and
    2.64%,  respectively,  for the  Large Cap Value  Fund  Institutional  Class,
    1.53%, 1.74% and 3.05% for the Large Cap Value Fund Investor Class.

(5) Annualized.

 *  Commencement of operations.

**  Calculated  based on  shares  outstanding  on the  first and last day of the
    respective  periods,  except for dividends and distributions,  if any, which
    are based on actual shares outstanding on the dates of distributions.

(1) Reflects waivers and reimbursements.

(2) The amount  shown for a share  outstanding  throughout  the period is not in
    accord  with the change in the  aggregate  gains and  losses in  investments
    during the period because the timing of sales and repurchases of Fund shares
    in relation to fluctuating net asset value during the period.

(3) Total  return is  calculated  assuming a purchase of shares on the first day
    and a sale of  shares  on the  last  day of each  period  reported  and will
    include  reinvestments of dividends and distributions,  if any. Total return
    is not annualized.

(4) Without the waiver of advisory,  administration  and transfer agent fees and
    without  the  reimbursement  of  certain  operating  expenses,  the ratio of
    expenses to average net assets annualized for the periods ended February 28,
    1999,  August 31, 1998 and August 31, 1997 would have been 1.28%,  1.57% and
    12.37%,  respectively,  for the Mid Cap Value Fund Institutional  Class, and
    1.53%, 1.66% and 12.62% for the Mid Cap Value Fund Investor Class.

(5) Annualized.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     The RBB Fund, Inc. ("RBB") was incorporated  under the laws of the State of
Maryland on February 29, 1988 and is registered under the Investment Company Act
of 1940, as amended,  (the "Investment  Company Act") as an open-end  management
investment company.  RBB is a "series fund", which is a mutual fund divided into
separate  portfolios.  The portfolio is treated as a separate entity for certain
matters  under  the  Investment  Company  Act,  and for  other  purposes,  and a
shareholder  of one  portfolio  is not deemed to be a  shareholder  of any other
portfolio.  Currently RBB has sixteen  investment  portfolios,  including Boston
Partners Large Cap Value Fund ("Large Cap Fund"),  Boston Partners Mid Cap Value
Fund ("Mid Cap Fund"),  Boston Partners Micro Cap Value Fund ("Micro Cap Fund"),
Boston Partners Market Neutral Fund ("Market  Neutral Fund") and Boston Partners
Bond Fund ("Bond Fund") (each a "Fund",  collectively  the  "Funds").  As of the
date hereof,  the Large Cap Fund offers three  classes of shares,  Institutional
Class,  Investor Class and Advisor Class.  The Mid Cap Fund, the Micro Cap Fund,
the  Market  Neutral  Fund and the Bond Fund each  offer two  classes of shares,
Institutional Class and Investor Class.

     RBB has  authorized  capital of thirty  billion  shares of common  stock of
which 19.83 billion are currently  classified into  ninety-seven  classes.  Each
class represents an interest in one of sixteen investment portfolios of RBB. The
classes have been grouped into fifteen  separate  "families," nine of which have
begun  investment  operations,  The Boston Partners Family of Funds includes the
Large Cap Fund,  which commenced  investment  operations on January 2, 1997, the
Mid Cap Fund,  which  commenced  operations on June 2, 1997, the Micro Cap Fund,
which commenced investment  operations on July 1, 1998, the Market Neutral Fund,
which  commenced  investment  operations on November 17, 1998 and the Bond Fund,
which commenced investment operations on December 30, 1997.

     PORTFOLIO VALUATION -- The net asset value of each Fund is determined as of
4:00 p.m.  eastern time on each business day. Each Fund's  securities are valued
at the last reported sales price on the national securities exchange or national
securities  market on which such shares are  primarily  traded.  If no sales are
reported, as in the case of some securities traded  over-the-counter,  portfolio
securities  are  valued  at the mean  between  the last  reported  bid and asked
prices.  Securities for which market  quotations  are not readily  available are
valued  at fair  market  value as  determined  in good  faith  by or  under  the
direction of RBB's Board of  Directors.  With the approval of the RBB's Board of
Directors,   each  Fund  may  use  a  pricing  service,  bank  or  broker-dealer
experienced  in such  matters  to  value  its  securities.  The  preparation  of
financial  statements  requires the use of estimates by  management.  Short-term
obligations  with  maturities  of 60 days or less are valued at  amortized  cost
which  approximates  market  value.  Expenses  and  fees,  including  investment
advisory and  administration  fees are accrued  daily and taken into account for
the purpose of determining the net asset value of the Funds.

     REPURCHASE  AGREEMENTS -- The Funds have agreed to purchase securities from
financial  institutions  subject to the seller's agreement to repurchase them at
an  agreed-upon  time  and  price  ("repurchase   agreements").   The  financial
institutions with whom the Funds enter into repurchase  agreements are banks and
broker/dealers  which  Boston  Partners  Asset  Management,   L.P.  (the  Funds'
investment  adviser or "Boston  Partners")  considers  creditworthy  pursuant to
criteria  approved by RBB's Board of  Directors.  The seller  under a repurchase
agreement  will  be  required  to  maintain  the  value  of  the  securities  as
collateral,  subject to the agreement at not less than the repurchase price plus
accrued  interest.  Boston  Partners  marks to  market  daily  the  value of the
collateral,  and,  if  necessary,  requires  the seller to  maintain  additional
securities,  to ensure  that the value is not less  than the  repurchase  price.
Default by or  bankruptcy  of the  seller  would,  however,  expose the Funds to
possible loss because of adverse market action or delays in connection  with the
disposition of the underlying securities.

                                   (UNAUDITED)

     INVESTMENT TRANSACTIONS AND INVESTMENT INCOME -- Transactions are accounted
for on the trade date. The cost of investments  sold is determined by use of the
specific  identification  method  for both  financial  reporting  and income tax
purposes  in  determining  realized  gains and losses on  investments.  Interest
income is  recorded  on the accrual  basis.  Dividend  income is recorded on the
ex-dividend  date. The Funds' net  investment  income (other than class specific
distribution  fees) and  unrealized  and realized gains and losses are allocated
daily to each class of shares based upon the relative  proportion  of net assets
of each class at the beginning of the day (after  adjusting for current  capital
share activity of the respective classes).

     DIVIDENDS AND  DISTRIBUTIONS  -- Dividends from net investment  income,  if
any, will be declared and paid at least annually to shareholders. Dividends from
net  investment  income  of  the  Bond  Fund  are  declared  and  paid  monthly.
Distributions  from net realized  capital gains,  if any, will be distributed at
least  annually.  Income  and  capital  gain  distributions  are  determined  in
accordance  with U.S.  federal  income tax  regulations  which may  differ  from
generally accepted accounting principles.

     U.S.  FEDERAL TAX STATUS -- No  provision is made for U.S.  federal  income
taxes as it is the Funds'  intention to qualify for and elect the tax  treatment
applicable to regulated  investment companies under Subchapter M of the Internal
Revenue Code of 1986, as amended,  and make the requisite  distributions  to its
shareholders which will be sufficient to relieve it from U.S. federal income and
substantially all excise taxes.

     SHORT SALES -- When the Adviser  anticipates that a security is overvalued,
it may sell the security  short by borrowing  the same security from a broker or
other institution and selling the security. A Fund will incur a loss as a result
of a short sale if the price of the borrowed security increases between the date
of the short sale and the date on which the Fund replaces such security.  A Fund
will realize a gain if there is a decline in price of the security between those
dates,  which decline  exceeds the costs of the borrowing the security and other
transaction  costs.  There can be no assurance that a Fund will be able to close
out a short position at any particular time or at an acceptable price.  Although
a Fund's  gain is limited to the amount at which it sold a security  short,  its
potential loss is limited only by the maximum  attainable  price of the security
less the price at which the security was sold.  Until a Fund replaces a borrowed
security,  it will maintain at all times cash, U.S.  Government  securities,  or
other liquid  securities in an amount which,  when added to any amount deposited
with a broker as collateral  will at least equal the current market value of the
security sold short. Depending on arrangements made with brokers, a Fund may not
receive any payments (including interest) on collateral deposited with them. The
Funds  will not make a short sale if,  after  giving  effect to such  sale,  the
market value of all securities  sold short exceeds 100% of the value of a Fund's
net assets.

2.   TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES
