SEMIANNUAL INVESTMENT ADVISER'S REPORT--JUNE 30, 1999

                                                                 August 12, 1999

Dear Shareholder:

   The domestic economy displayed  surprising health during the first six months
of 1999,  fueling  expectations  that the Federal  Reserve would raise  interest
rates  to ward off  potential  inflation.  Indeed,  at its May  meeting  the Fed
announced a bias toward raising rates (it  specifically  noted the potential for
wage increases to outpace productivity gains). In a widely anticipated move, and
one preceded by a  significant  rise in  short-term  yields,  the Fed raised the
federal funds target rate by 25 basis points, to 5%, on June 30.

   Warburg  Pincus  Cash  Reserve  Fund  continued  to  emphasize   high-quality
securities  through the period, as is its general policy.  The fund's annualized
seven-day  yield as of June 30, 1999 was 4.47%  (4.35%  without  waivers  and/or
reimbursements),  down from 4.61% for the period ended  December  31, 1998.  The
fund had net assets of $446.6 million as of that date, up from $430.0 million at
the start of the period.  The fund's average weighted  seven-day  maturity as of
June 30, 1999 was 59 days, up from 39 days on December 31, 1998.

   The fund will  continue to emphasize  the  highest-quality  securities  in an
effort to provide competitive returns without  compromising safety and stability
of principal. We appreciate your continued support and investment in the fund.

WARBURG PINCUS NEW YORK TAX EXEMPT FUND
SEMIANNUAL INVESTMENT ADVISER'S REPORT--JUNE 30, 1999
- --------------------------------------------------------------------------------
                                                                 August 12, 1999

Dear Shareholder:

   Fiscally New York state has  continued to benefit from an improving  economy.
Particularly  noteworthy  is the state's  year-over-year  economic  growth rate,
which in April  matched the national  rate for the first time in years,  and its
private-sector  employment,  which currently stands at an all-time high.  Credit
concerns,  however,  remain on the horizon.  The state's  large and growing debt
burden,  dependence  on the  financial-services  sector and  failure to build up
reserves during the economic  expansion are factors that could negatively impact
the state should the national economy enter recession. In addition, the state is
once again  late in passing  its (as  usual,  politically  contentious)  budget.
Combined,  these  factors  limit the upside  potential  for the  state's  credit
ratings.

   New York City's economy also continues to improve.  As of February,  the city
had  recovered  employment  lost during the 1989-1992  recession,  and the state
comptroller is currently  projecting a $2.1 billion surplus for fiscal-year 1999
(which would mark three straight years of record surpluses).

   Warburg Pincus New York Tax Exempt Fund's  seven-day  annualized  yield as of
June 30 was 2.89% (without waivers and/or  reimbursements,  the fund's seven-day
annualized yield would have been 2.75%). Its seven-day average weighted maturity
as of that date was 46 days.  The fund had net assets of $148.2  million on June
30, 1999.

   The fund's  assets  during the  period  peaked in late  January at about $195
million  and reached a low of $140  million in April.  This  reflected  seasonal
factors  (e.g.,  April tax  payments)  that drive flows for  money-market  funds
generally.  In terms of strategy,  we kept the fund's average weighted  maturity
within the 25- to 35-day range over much of the period,  since yields were often
actually lower among longer-dated municipal money-market securities. We began to
extend the fund's  maturity  in May,  however,  when  market  expectations  of a
Federal Reserve  interest-rate hike caused yields farther out on the yield curve
to rise.

   We will  continue  to strive to  provide  investors  a high  level of current
income that is exempt from federal, New York state and New York City taxes as is
consistent  with  preservation  of capital and  liquidity.  We  appreciate  your
continued support and investment in the fund.

with preservation of capital and liquidity.

   Certain  New York state and New York City  municipal  obligations  in the New
York Tax Exempt  Fund may be  obligations  of issuers  which rely in whole or in
part on New York state or New York City revenues,  real property taxes, revenues
from health care  institutions,  or  obligations  secured by  mortgages  on real
property.  Consequently,  the possible effect of economic conditions in New York
or of changes in New York regulations on these obligations must be considered.

   The net asset value of each fund is determined twice daily as of noon and the
close of regular trading on the New York Stock Exchange. Each fund's investments
are valued under the amortized  cost method,  which  approximates  market value,
unless a fund's Board of Directors  determines  that using this method would not
reflect an investment's  value.  Amortized cost involves  valuing a fund holding
initially  at its cost and then assumes a constant  amortization  to maturity of
any  discount  or  premium.  The  amortized  cost  method  ignores any impact of
fluctuating interest rates.

   Security  transactions  are  accounted  for on a trade date  basis.  Interest
income  is  recorded  on the  accrual  basis.  The cost of  investments  sold is
determined  by use of the  specific  identification  method  for both  financial
reporting and income tax purposes.

   Dividends  from net  investment  income are declared  daily and paid monthly.
Distributions  of net  realized  capital  gains,  if any,  are declared and paid
annually,  although the Cash Reserve Fund may declare and pay short-term capital
gains, if any, periodically as the Board of Directors determines.  To the extent
that a net realized  capital  gain can be reduced by a capital  loss  carryover,
such gain will not be  distributed.  Income and capital gain  distributions  are
determined in accordance  with federal income tax  regulations  which may differ
from generally accepted accounting principals.

1. SIGNIFICANT ACCOUNTING POLICIES -- (CONT'D)

   No provision is made for federal income taxes as it is each fund's  intention
to continue to qualify for and elect the tax  treatment  applicable to regulated
investment  companies under the Internal  Revenue Code of 1986, as amended,  and
make the requisite distributions to its shareholders which will be sufficient to
relieve it from federal income and excise taxes.

   Each fund may enter into repurchase agreement  transactions.  Under the terms
of a typical  repurchase  agreement,  a fund  acquires a security  subject to an
obligation of the seller to  repurchase.  Securities  pledged as collateral  for
repurchase agreements are held by the fund's custodian bank until the agreements
mature.  Each  agreement  requires  that the market value of the  collateral  be
sufficient to cover payments of interest and principal; however, in the event of
default or  bankruptcy  by the other party to the  agreement,  retention  of the
collateral may be subject to legal proceedings.

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

   The funds have an  arrangement  with their  transfer  agent whereby  interest
earned  on  uninvested  cash  balances  was used to  offset a  portion  of their
transfer  agent  expense.  For the six  months  ended June 30,  1999,  each Fund
received credits or reimbursements under this arrangement as follows:

           FUND                                            AMOUNT
           ----                                           --------

2. INVESTMENT ADVISER AND SUB-ADVISER, CO-ADMINISTRATORS AND
    DISTRIBUTOR

   On July 6, 1999,  Credit  Suisse  Asset  Management,  LLC (CSAM)  became each
fund's  investment  adviser  as a result  of the  completion  of the  previously
announced acquisition of Warburg Pincus Asset Management,  Inc. (WPAM) by Credit
Suisse Group (Credit  Suisse) and the  combination of WPAM with Credit  Suisse's
existing U.S. asset management business.  CSAM is an indirect  wholly-owned U.S.
subsidiary of Credit Suisse. For its investment advisory services, CSAM receives
a fee  calculated  at an annual  rate of .25% of each fund's  average  daily net
assets.  For the six months ended June 30, 1999,  investment  advisory  fees and
voluntary waivers were as follows:

8. YEAR 2000 COMPLIANCE

   Many services  provided to the portfolios and their  shareholders  by CSAMand
certain of its affiliates (CSAM Service  Providers) and the funds' other service
providers rely on the functioning of their  respective  computer  systems.  Many
computer systems cannot distinguish the year 2000 from the year 1900,  resulting
in potential  difficulty in performing  various  calculations (Year 2000 Issue).
The Year 2000 Issue could  potentially have an adverse impact on the handling of
security  trades,  the  payment of  interest  and  dividends,  pricing,  account
services and other portfolio operations.

8. YEAR 2000 COMPLIANCE (CONT'D)

   The CSAM Service  Providers  recognize the  importance of the Year 2000 Issue
and are taking appropriate steps necessary in preparation for the year 2000. The
CSAM Service  Providers  anticipate  that their  systems and those of the funds'
other major  service  providers  will be adapted in time for the Year 2000.  The
CSAM Service  Providers have completed mission critical systems testing and have
participated in industry-wide  testing programs.  In addition,  the CSAM Service
Providers are formulating a contingency  plan to address the Year 2000 Issue and
anticipate completion of the plan by the end off the third quarter of 1999.

   The  CSAMService  Providers  continue  to monitor the Year 2000 Issue and its
potential  impact on the funds.  However,  there can be no assurance  that these
steps will be sufficient to avoid any adverse  impact on the funds nor can there
be any assurance that the Year 2000 Issue will not have an adverse effect on the
funds' investments or on global markets or economies, generally.
