                     BOSTON PARTNERS FAMILY OF MUTUAL FUNDS
                           PORTFOLIO MANAGER'S LETTER

August 31, 1999

Dear Shareholder:

     1999 has provided varied  investment  results for value managers.  At times
Boston  Partners  has shown its stripes,  outperforming  the S&P 500 for the 2nd
Quarter for example.  At times,  with the lack of breadth in the market,  Boston
Partners  has  disappointed.  Please  take  a  moment  to  read  the  investment
discussion  of each  of the  Boston  Partners  Family  of  Funds.  We hope  each
discussion  will  provide  the market  details  as well as why we are  confident
Boston Partners Funds will vault to our top position again.

BOSTON PARTNERS LARGE CAP VALUE FUND

     The Boston  Partners Large Cap Value Fund began a volatile  period in 1998,
one that has continued in 1999. The net result of this  volatility is the Fund's
underperformance  of the S&P 500.  We spend a great deal of time  analyzing  the
major  market  indices,  such as the S&P 500 and the Russell  1000 Value.  It is
clear from our analysis that the single most important factor in our performance
shortfall  year to date through August 1999, was our low price to earnings ratio
bias. As we mentioned in past letters, performance has been very much correlated
with P/E; the higher the P/E, the better the performance.  Accordingly,  one can
extrapolate that our "deeper" value characteristics contributed to the shortfall
versus the value indices.  By selling stocks in a disciplined  fashion once they
achieved   their  price   (valuation)   targets,   we  have   maintained   value
characteristics (P/E, P/B).

     With respect to our 1999 YTD returns, it is important to look at the period
in three different segments.  The first quarter of 1999, was a repeat of 1998 in
terms of the usual  narrowness  of the  market and the fact that high P/E stocks
again outperformed low P/E stocks.

     The second quarter 1999 brought about a much-anticipated  broadening of the
market.   The  performance  of  the  median  stock   approximated  that  of  the
capitalization weighted average and lower P/E stocks generally performed as well
as or better  than the higher P/E  stocks.

     The months of July and August 1999 have  continued a trend that was similar
to 1998 and the first  quarter of this year,  where  there was a wide  disparity
between  the growth  and value  styles of  investing.  In fact,  in August,  the
disparity between the Russell 1000 Growth Index and the Russell 1000 Value Index
(at 5.34%) was the second largest we've experienced in 93 months. The reason for
the  strength  in the  growth  style was the  resiliency  of  technology  issues
combined  with  weakness  in  consumer  stocks.  During a month when the Federal
Reserve increased  interest rates,  Consumer Cyclicals and Financial stocks sold
off, while Technology and high P/E Pharmaceutical  stocks  flourished.  The four
biggest  contributors  in both the S&P 500 and the Russell  1000 Growth  Indexes
were  Intel,  Microsoft,  Cisco and Dell;  names that we have seen lead the pack
before.  The average P/E for these markets leaders  currently stands at 57x! Our
portfolio averages 15x.

     There have been a few  periods of time in the past 25 years  where high P/E
stocks  have  outperformed  lower  P/E  stocks.  In each  of  those  cases,  the
investment  managers that  performed best after those periods have been the ones
that maintained their commitment value investing.  Accordingly,  Boston Partners
maintains its strong  conviction about the current portfolio and is confident in
the philosophy, the process, and the people implementing it.

BOSTON PARTNERS MID CAP VALUE FUND

     While the Boston  Partners  Mid Cap Value Fund  exceeded  the Russell  2500
benchmark in the early months of 1999,  several factors since adversely affected
the portfolio,  which led to an underperformance for year-to-date through August
1999. Market conditions  deteriorated  throughout the period driven by a tighter
Federal  Reserve Policy and a rash of  significant  earnings  shortfalls  across
several industries.

     Year to date,  growth  indices have  significantly  outperformed  the value
indices in the mid capitalization  market.  This  outperformance has been almost
entirely driven by the technology  sector. We have found selective ideas in this
sector, which meet our disciplined,  value-based investment philosophy, but have
maintained  a  significant  underweight  in this  sector  for the  past  several
quarters.  Presently,  we belive  that the  technology  sector is  significantly
overvalued,  and that  expectations  for earnings  growth within this sector are
excessive.  Poor  performance  in the Finance sector also detracted from overall
performance.

     We continue to maintain our  overweight in the energy sector.  However,  we
have shifted the focus of the holdings away from the companies with refining and
marketing  exposure or gas  reserves.  We believe  the lower  crude  inventories
created by  production  cutbacks  will lead to expanding  refining  margins thus
resulting  in much  better  than  expected  earnings  for  companies  like Tosco
Corporation,  Valero Energy, and Tesoro Petroleum.  In addition,  we believe the
supply/demand dynamics are much better for gas than oil.

     Presently,   that  larger  capitalization  stocks  are  significantly  more
expensive  than smaller  capitalization  stocks.  This valuation gap has reached
historic  proportions.  We believe  there are  several  catalysts  in place that
should  serve to help  close  this gap  which we belive  will  result in mid cap
outperformance.  These catalysts include  accelerating stock buybacks by smaller
companies,  increased  merger and  acquisition  activity,  and leveraged  buyout
activity.

BOSTON PARTNERS BOND FUND

     Following three  consecutive  quarters of rising interest rates and falling
bond prices,  bond prices fell again.  The Federal  Reserve  boosted the Federal
Funds rate another .25% in August  which,  following a similar  increase in May,
takes back two of the three late 1998 "insurance  policy" cuts.  Reports showing
continued strong economic growth,  better global growth with further recovery in
Asia, and rising  employment  costs suggest the Federal  Reserve may raise rates
again later this year.

     While  interest  rates rose and then fell during the period  they  finished
8-12 basis points  higher.  From Federal  Funds at 5.25% to long  Treasuries  at
6.05%,  the  yield  curve is  compressed  into just 80 basis  points.  This flat
configuration  reflects  confidence that the Federal  Reserve will  successfully
contain  inflationary  pressures  stemming from above-trend  economic growth and
tight labor markets.  Mortgages and corporates generally  underperformed in July
and August 1999.

     Beneath the undulating  surface of rising and then falling  Treasury rates,
the  performance of "spread  product" such as corporate and mortgage  securities
endured considerable volatility.  Reminiscent of last year, yield spreads in the
mortgage and corporate  markets widened to surprising  levels. A strong economic
environment is generally positive for corporate yield spreads.  Stable or higher
interest rates usually  benefit  mortgages,  due to diminished  risk of mortgage
prepayments.  However, competition from swap spreads, increased corporate supply
ahead of potential Y2K problems,  and the withdrawal of liquidity by dealers and
hedge funds  combined to hurt the relative  valuation of corporate  and mortgage
securities. The high yield and emerging market sectors were especially hard hit.

                                       2

<PAGE>

     Our  strategies  remain  unchanged as we believe the yield  advantage  from
mortgages and  corporates  is unusually  attractive.  GNMA 6.5%'s,  for example,
offer a 150 basis points yield advantage to comparable Treasuries. With a dollar
price  of  95  we  belive  these  securities  have  little  prepayment  risk,  a
substantial  yield  advantage  and  excellent  liquidity.  We belive  this is an
exceptional advantage in an environment of 5.5% government rates.

     Corporate bonds generally underperformed during the period. Corporate yield
spreads  widened with some spreads  reverting back to the  distressed  levels of
late last year. The best performing corporate sectors included Asian sovereigns,
energy,  and chemicals.  We continue to favor less cyclical  sectors such as the
banking,  utilities,  and communications  sectors. Our core holdings include The
Equitable,  MetroNet,  Hydro-Quebec  and  Ford  Motor.  These  bonds  exhibit  a
combination of attractive yields relative to their peer group and improving cash
flows as  evaluated  by our industry  research  analysts.  During the quarter we
enjoyed 9 upgrades  versus 3  downgrades.  Since  mid-1995  we have  enjoyed 133
upgrades  versus 16  downgrades.  This 8.3 to 1 ratio  compares  favorably  to a
combined  Moody's and  Standard & Poor's ratio of less than 1 to 1 over the same
period.

     Risk  control  is  extremely  important  in our  management  of the  Boston
Partners  Bond Fund.  We check daily to ensure  that the level of interest  rate
risk is closely  matched to the Lehman  Aggregate  Index.  Our  procedures  also
include  attention  to yield  curve  exposure  relative  to  benchmarks,  sector
weightings, and diversification.

     With  minimal  interest  rate and  yield  curve  exposure  relative  to the
benchmark,  the portfolio is  significantly  overweighted in the higher yielding
mortgage and corporate sectors.  Within the mortgage sector we emphasize current
coupon  and  seasoned  mortgages  with less  prepayment  risk,  and  within  the
corporate sector we focus on issuers with improving credit  fundamentals.  Yield
and the  reinvestment  of coupon  income drive fixed income  returns in the long
run.  Therefore,  we remain  committed to maintaining a yield advantage and risk
controls, as we believe it is the most consistent way to add value over time.

BOSTON PARTNERS MICRO CAP VALUE FUND

     While year to date performance for the Boston Partners Micro Cap Value Fund
remains  positive,  the  frustration  in the  marketplace  as a  value  investor
continues.  Growth stocks continue to outperform  value stocks for the six month
period as well as year to date,  driven  largely by the technology  sector.  Our
disciplined,  value based investment  philosophy leads to an  underweighting  in
this  sector  (upwards  of 20% for the CRSP 9-10 Index  versus 7% for the Boston
Partners Micro Cap Value Fund), and our lack of exposure to this sector has been
the single largest  contributor to our  underperformance of the CRSP 9-10 Index.
Presently, we belive that the technology sector is significantly overvalued, and
that expectations for earnings growth within this sector are excessive.

     Additionally,  the Finance  Sector has  disappointed  investors in 1999, as
most stocks have  underperformed.  Our overweighting has hurt performance in the
period.  The  incredible  values  that are being  created in this  sector,  lead
investors to consider  finance stocks to be "good buys" at this time. The Boston
Partners Micro Cap Value Fund recognizes these values,  but remains committed to
finding a catalyst for change,  before  purchasing some of the strong  insurers,
brokers and banks.

     Presently,  we see that larger capitalization stocks are significantly more
expensive  than smaller  capitalization  stocks.  This valuation gap has reached
historic  proportions.  We believe  there are  several  catalysts  in place that
should   serve  to  help  close  this  gap  which  will   result  in  micro  cap
outperformance.  These catalysts include  accelerating stock buybacks by smaller
companies,  increased  merger and  acquisition  activity,  and leveraged  buyout
activity.

BOSTON PARTNERS MARKET NEUTRAL FUND

     The market environment of the past eight months of higher price to earnings
stocks  outperforming  lower price to earnings stocks has been well  documented.
Like all of Boston Partner's  portfolios,  the Market Neutral Fund is based on a
value  philosophy and process.  Value investing  produces  positive returns over
time, but not all of the time. This recent period,  while short, is one of those
times. Our slight loss, year-to-date, but it certainly underperforms our goal of
besting the Salomon Brothers 30 Day T-Bill Rate.

     Our  Market  Neutral  Fund  invests  long in  stocks  that we  believe  are
undervalued with sound business  fundamentals and positive business momentum. We
will  sell  short  stocks  that  are  overvalued  with  deteriorating   business
fundamentals and declining business trends. In the first ten and one half months
technology stocks (more  specifically  internet stocks) that were overvalued and
had no strong balance sheets or earnings, continued to perform well. Our lack of
exposure to this sector on the long side of the Market Neutral Fund was a reason
for our underperformance.  While we do not know when this phenomena will change,
we do belive that these companies'  prices cannot continue to grow. We belive at
some point in time,  fundamentals  will become important again.  This is when we
belive the Boston Partners Market Neutral Fund will excel.

     The short  holdings in the Boston  Partners  Market Neutral Fund have added
basis  points to the  fund.  During  the most  recent  period  we have  found an
abundance  of  stocks  whose  market  values  were  expensive,   with  financial
statements  that were  unimpressive,  and whose trends towards  improvements  in
their business were negative. These short stocks that have performed well in the
recent period and include Party City Corporation,  Planet  Hollywood,  and Shick
Technology.

YEAR 2000

     The Fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000.  While Year 2000  issues  could have a  negative  effect on the Fund,  the
Fund's  investment  adviser is  currently  working to avoid such  problems.  The
Fund's  investment  adviser is also working  with other  systems  providers  and
vendors  servicing the Portfolios to determine their systems'  ability to handle
Year 2000  problems.  There is no  guarantee,  however,  that  systems will work
properly on or after  January 1, 2000.  Year 2000 problems may also hurt issuers
whose securities the Fund holds or securities markets generally.

                          NOTES TO FINANCIAL STATEMENTS

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"). The Large Cap
Fund, 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 20.03 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 the 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 RBB's Board of
Directors,   each  Fund  may  use  a  pricing  service,  bank  or  broker-dealer
experienced in such matters to value its securities. 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.

     USE OF ESTIMATES -- The  preparation of financial  statements in conformity
with  generally  accepted  accounting  principles  requires  management  to make
estimates  and  assumptions  that  affect  the  reported  amounts  of assets and
liabilities  and disclosure of contingent  assets and liabilities at the date of
the  financial  statements  and the  reported  amounts of revenues  and expenses
during the period. Actual results could differ from those estimates.

                     BOSTON PARTNERS FAMILY OF MUTUAL FUNDS
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     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.

     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'  investment  income,  expenses  (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, are 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, are  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.  These differences  include the treatment of non-taxable
dividends,  expiring capital loss  carryforwards,  foreign  currency  gain/loss,
partnerships,  and losses deferred due to wash sales and excise tax regulations.
Permanent book and tax basis differences  relating to shareholder  distributions
will result in reclassifications to paid in capital.

     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
all excise taxes.

                     BOSTON PARTNERS FAMILY OF MUTUAL FUNDS
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     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  unlimited  and will be 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

     Boston  Partners Asset  Management,  L.P.  serves as the Funds'  investment
adviser. For its advisory services, Boston Partners is entitled to receive 0.75%
of the Large Cap Fund's  average  daily net assets,  0.80% of the Mid Cap Fund's
average  daily  net  assets,  1.25% of the Micro Cap  Fund's  average  daily net
assets, 1.50% of the Market Neutral Fund's average daily net assets and 0.40% of
the Bond  Fund's  average  daily net  assets,  each  computed  daily and payable
quarterly.

     The adviser has voluntarily  agreed to limit the Large Cap Fund and the Mid
Cap Fund's total  operating  expenses for the current and the  following  fiscal
year to the extent that such expenses  exceeded  1.00% of the Large Cap Fund and
the Mid Cap Funds' average daily net assets.  The adviser has voluntarily agreed
to limit the Micro Cap Fund's total  operating  expenses for the current and the
following fiscal year to the extent that such expenses exceed 1.55% of the Micro
Cap Fund's average daily net assets. The adviser has voluntarily agreed to limit
the Market  Neutral  Fund's  total  operating  expenses  for the current and the
following  fiscal  year to the extent  that such  expenses  exceed  2.50% of the
Market  Neutral  Fund's  average daily net assets.  The adviser has  voluntarily
agreed to limit the Bond Fund's total operating expenses for the current and the
following  fiscal year to the extent that such  expenses  exceeded  0.60% of the
Bond Fund's average daily net assets. As necessary,  this limitation is effected
in waivers  of  advisory  fees and  reimbursements  of  expenses  exceeding  the
advisory fee. For the year ended August 31, 1999,  (unless otherwise  indicated)
investment  advisory  fees,  waivers  and  reimbursements  of  expenses  were as

impact on the net asset value of the Fund and are designed  generally to present
undistributed income and realized gains on a tax basis which is considered to be
more  informative to the  shareholder.  As of August 31, 1999, the Fund recorded
the following reclassification to increase (decrease) the accounts listed below:

                                            ACCUMULATED
                        UNDISTRIBUTED      NET REALIZED       ADDITIONAL

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Directors of The RBB Fund, Inc.:

In our opinion, the accompanying statement of assets and liabilities,  including
the portfolios of investments,  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 Boston  Partners Large Cap Value
Fund,  Boston Partners Mid Cap Value Fund, Boston Partners Micro Cap Value Fund,
Boston Partners  Market Neutral Fund and Boston  Partners Bond Fund,  separately
managed  portfolios of The RBB Fund, Inc. (the "Fund"),  at August 31, 1999, the
results of their  operations for the year (or period) then ended and the changes
in their  net  assets  and the  financial  highlights  for  each of 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 Fund'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 August
31, 1999 by correspondence with the custodians and brokers, provide a reasonable
basis for the opinion expressed above.

Each Fund is required by  Subchapter M of the Internal  Revenue Code of 1986, as
amended,  to advise its  shareholders  within 60 days of each Fund's fiscal year
end  (August  31,  1999) as to the U.S.  federal  tax  status  of  distributions
received by each Fund's  shareholders in respect of such fiscal  year.During the
fiscal year ended August 31, 1999, the following dividends and distributions per
share were paid by each of the Funds:

Boston Partners Micro Cap Fund ........       --            --             --             --
Boston Partners Bond Fund .............     0.62          0.55           0.11           0.11
</TABLE>

The percentage of total ordinary income  dividends from the Large Cap Value Fund
and Mid Cap Value Fund qualifying for the corporate dividends received deduction
for each Fund is 100%.

These  amounts were  reported to  shareholders  as income in 1998.  Because each
Fund's fiscal year is not the calendar year,  another  notification will be sent
with respect to calendar year 1999. The second notification,  which will reflect
the amount,  if any, to be used by calendar year taxpayers on their U.S. federal
income tax returns,  will be made in conjunction  with Form 1099-DIV and will be
mailed in January 2000.

Foreign  shareholders  will generally be subject to U.S.  withholding tax on the
amount of their  dividend.  They will generally not be entitled to a foreign tax
credit or deduction for the withholding taxes paid by the Funds, if any.

In general,  dividends received by tax-exempt recipients (e.g., IRAs and Keoghs)
need not be reported as taxable  income for U.S.  federal  income tax  purposes.
However, some retirement trusts (e.g., corporate, Keogh and 403(b)(7) plans) may
need this information for their annual information reporting.

Shareholders  are advised to consult  their own tax advisers with respect to the
tax consequences of their investment in the Funds.
