Dear Shareholder:                                                August 15, 1997
 
For the six-month period ended June 30, 1997, short-term interest rates, in the
overnight to one-year area of the yield curve, were often volatile. During the
first three months of 1997 interest rates rose across the yield curve, but
following the Federal Reserve's tightening of monetary policy in late March (the
Fed raised its targeted federal-funds rate by 25 basis points, to 5.50%),
interest rates declined dramatically in the April-through-June span. The market
was also buoyed by continued benign inflation and economic data indicating
slowing demand (Fed Chairman Alan Greenspan had cited stronger demand as a
reason for the earlier tightening). As the market rallied in the second half of
the period, yields narrowed between securities in the three-to-nine-month area
and those in the 10-to-12-month range.
 
The annualized yield for Warburg Pincus Cash Reserve Fund (the 'Fund') for the
seven-day period ended June 30, 1997 was 5.10% (4.96% without waivers and/or
reimbursements), up from 5.03% for the period ended December 31, 1996. Net
assets declined to $372.2 million, down from $451.6 million six months ago. The
Fund's average weighted maturity on June 30, 1997, was 49 days, down from 54
days on December 31, 1996.
 
The Fund will continue to emphasize high-quality securities in order 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

Dear Shareholder:                                                August 15, 1997
 
   New York state has a broad and diverse economic base, enhanced by substantial
wealth and resources. The state's fiscal condition continues to improve, which
is reflected in fiscal 1997's estimated $1.5 billion surplus. This represents
the fifth consecutive year positive budget results have been achieved since the
recession of the early 1990s. Unfortunately, however, the state, once again,
failed to pass a budget in a timely manner. This persistent lateness and the
highly political nature of the budget process will likely preclude any credit
rating upgrade from the major credit agencies in the foreseeable future.
 
   New York City, which continues to see steady growth, likewise had very
positive budget results. It closed its 1997 fiscal year on June 30 with its
largest surplus ever, an estimated $856 million. Though Wall Street's banner
year had a disproportionate effect on the City's finances, the City also
benefited from growth within areas such as the hotel and real-estate industries.
While the City's recently improved fiscal situation is heartening, it should be
noted that there are substantial budgetary shortfalls that remain to be
addressed.
 
   The tax-free market experienced seasonal asset volatility during the six-
month period ended June 30, 1997. Total tax-exempt assets rose to a record
$152.7 billion in mid-April as investors parked their money to pay income taxes,
and then decreased to $143.7 billion by the period-end. Assets for Warburg
Pincus New York Tax Exempt Fund (the 'Fund') followed the same pattern,
increasing to $158.8 million by mid-April and then declining to $113.6 million
by June 30. The market's cash outflow created buying opportunities as demand for
paper decreased and yields increased.
 
   The Fund's strategy was to lock in rates at attractive levels, while
maintaining liquidity to meet redemptions. Notes and commercial paper were
acquired by the Fund to take advantage of the rising yields, and consequently
the average weighted maturity of the Fund jumped from the 20 to 30 day range to
the 50 to 65 day range in the latter part of the period (the Fund's maturity was
63 days as of June 30). The Fund's 12-month return as of June 30, 1997, was
3.00%, outperforming IBC's New York tax-exempt funds by eight basis points. The
Fund's seven-day annualized yield was 3.34% (3.17% without waivers and/or
reimbursements), up from 3.31% on December 31.*
 
   The Fund seeks to provide investors with a high level of current income that
is exempt from federal, New York state and New York city personal income taxes
as is consistent with preservation of capital and liquidity. We appreciate your
continued support and investment in the Fund.
 
Eugene L. Podsiadlo
President

WARBURG PINCUS CASH RESERVE AND NEW YORK TAX EXEMPT FUNDS
NOTES TO FINANCIAL STATEMENTS
June 30, 1997 (Unaudited)
- --------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
   The Warburg Pincus Cash Reserve Fund (the 'Cash Reserve Fund') and the
Warburg Pincus New York Tax Exempt Fund (the 'New York Tax Exempt Fund') are
registered under the Investment Company Act of 1940, as amended (the '1940
Act'), as diversified and non-diversified, open-end management investment
companies, respectively.
 
   Investment objectives for each Fund are as follows: the Cash Reserve Fund is
designed to provide investors with high current income consistent with liquidity
and stability of principal; the New York Tax Exempt Fund is designed to provide
investors with as high a level of current income that is exempt from federal,
New York state and New York city personal income taxes as is consistent 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 issues 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 as of noon and the close of
regular trading on the New York Stock Exchange on each day, except on days when
the Exchange is closed. Each Fund's investments are valued under the amortized
cost method which approximates current market value. Under this method,
investments are valued at cost when purchased and thereafter a constant
proportionate amortization of any discount or premium is recorded until maturity
of the investment.
 
   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 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 principles.
 
   No provision is made for federal 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 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 an underlying security
subject to an obligation of the seller to repurchase. The value of the
underlying security collateral will be maintained at an amount at least equal to
the total amount of the purchase obligation, including interest. The collateral
is in the Fund's possession through its custodian.
 
   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 Cash Reserve Fund and the New York Tax Exempt Fund have, effective March
1, 1997, each changed their fiscal and tax year-ends from February 28th to
December 31st, which was approved by the Funds' Board of Directors on January
15, 1997.
 
   The Funds have an arrangement with their transfer agent whereby interest
earned on uninvested cash balances was used to offset a portion of the transfer
agent expense. For the period ended June 30, 1997, each Fund received credits or
reimbursements as follows:
