              formerly Waterhouse Investors Cash Management Fund,
                                    Inc.(A)
 
DEAR SHAREHOLDER:
- --------------------------------------------------------------------------------
 
I am pleased to provide you with the Waterhouse Investors Cash Management Funds
(the "Fund") semiannual report for the six months ended April 30, 1998.
 
During the year, each of the Money Market, U.S. Government and Municipal
Portfolios attempted to provide maximum current income from high quality money
market securities while maintaining a conservative investment portfolio to
ensure safety of principal. By April 30, 1998, assets in the three Portfolios
increased to a total of $3.1 billion.
 
PORTFOLIO RESULTS *
For the six months ended April 30, 1998, the three money market Portfolios had
the following annualized returns.**
 
   * The Money Market Portfolio had an annualized return of 5.04% and a current
     yield of 4.99%.
 
   * The U.S. Government Portfolio had an annualized return of 4.91% and a
     current yield of 4.86%.
 
   * The Municipal Portfolio had an annualized return of 3.00%, a taxable 
     equivalent return of 4.69%(1), a current yield of 2.98% and a taxable
     equivalent yield of 4.66%(1).
 
The economy has grown at a 3% to 5% pace for the last six months, while
inflation has been virtually non-existent. We expect the Federal Reserve to
maintain a watchful eye over the economy, as they look for any signs of an
uptick in inflation. Economic events in Asia have increased the possibility that
the U.S. economy will slow down which could prevent the Federal Reserve from
raising interest rates. In light of the current economic environment, the
average maturities of the Portfolios are being maintained at or below the
industry average to react quickly to changes in short-term interest rates.
 
Thank you for investing in the Fund and for your confidence in us. For the
second consecutive year, Waterhouse Securities was ranked #1 discount broker by
SmartMoney Magazine.(2) According to the SmartMoney article "we set out to
identify the single best discount broker--that is the one firm with the best mix
of price, product, service and reputation."
 
We look forward to continuing to meet your expanding investment needs in the
years to come.
 
Sincerely,
 
/s/ Lawrence M. Waterhouse, Jr.

(A) As of December 18, 1997, Waterhouse Investors Cash Management Fund, Inc.
    changed its name to Waterhouse Investors Family of Funds, Inc.
 
* An investment in the Fund is neither FDIC-insured nor guaranteed by the U.S.
Government and is not a deposit or obligation of, or guaranteed by, any bank.
There can be no assurance that a portfolio will be able to maintain a stable net
asset value of $1 per share.
 
** These returns are based on a constant investment throughout the period,
include reinvestment of dividends and reflect a net return to the shareholder
after all expenses, inclusive of fee waivers. For the six months ended April 30,
1998, the Investment Manager and its affiliates waived a portion of their fee
for the Money Market, U.S. Government and Municipal Portfolios. Without these
fee waivers in effect, the annualized returns and current yields would have been
4.89% and 4.84% for the Money Market Portfolio, 4.83% and 4.78% for the U.S.
Government Portfolio and 2.88% and 2.86% for the Municipal Portfolio. The
annualized taxable equivalent return and yield for the Municipal Portfolio would
have been 4.50% and 4.47%, respectively. The yield more closely reflects the
current earnings of the Portfolios than the total return.
 
(1) Taxable equivalent return and yield at 36% marginal federal income tax rate.
 
(2) As compared to 22 discount brokerage firms in the SmartMoney Magazine, July
    1998 issue.

"Portfolio" and collectively the "Portfolios"), each of which is a diversified
investment portfolio. The investment objective of each of the Money Market
Portfolio, the U.S. Government Portfolio and the Municipal Portfolio is to seek
maximum current income to the extent consistent with liquidity and preservation
of capital. The Money Market Portfolio has the flexibility to invest broadly in
U.S. dollar-denominated securities of domestic and foreign issuers. The U.S.
Government Portfolio offers an added measure of safety by investing exclusively
in obligations issued or guaranteed by the U.S. government, its agencies or
instrumentalities. The Municipal Portfolio offers investors federally tax-exempt
income by investing primarily in municipal securities.
 
NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of the Fund's significant accounting policies:
 
Computation of Net Asset Value -- It is each Portfolio's policy to maintain a
continuous net asset value of $1.00 per share. Each Portfolio has adopted
certain investment, portfolio valuation and dividend and distribution policies
to enable it to do so. There is no assurance, however, that each Portfolio will
be able to maintain a stable net asset value of $1.00 per share.
 
Securities Valuation -- Each Portfolio's securities are valued using the
amortized cost method, which approximates market value. The amortized cost
method involves initially valuing a security at its original cost and thereafter
assuming a constant amortization to maturity of any discount or premium.
 
Repurchase Agreements -- The Fund may enter into repurchase agreements with
financial institutions deemed to be creditworthy by the Fund's Investment
Manager, subject to the seller's agreement to repurchase and the Fund's
agreement to resell such securities at a mutually agreed upon price. Securities
purchased subject to repurchase agreements are deposited with the Fund's
custodian and, pursuant to the terms of the repurchase agreement, must have an
aggregate market value greater than or equal to the repurchase price plus
accrued interest at all times. If the value of the underlying securities falls
below the value of the repurchase price plus accrued interest, the Fund will
require the seller to deposit additional collateral by the next business day. If
the request for additional collateral is not met, or the seller defaults on its
repurchase obligation, the Fund maintains the right to sell the underlying
securities at market value and may claim any resulting loss against the seller.
 
Investment Income -- Interest income is accrued as earned. Discounts and
premiums on securities purchased are amortized in accordance with income tax
regulations which approximate generally accepted accounting principles.
 
Distributions to Shareholders -- Dividends arising from net investment income
are declared daily and paid monthly. With respect to each Portfolio, net
realized short-term capital gains, if any, may be distributed during the year
and net realized long-term capital gains, if any, are distributed at least once
each year. Income distributions and capital gain distributions are determined in
accordance with income tax regulations.

    NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 1998 (UNAUDITED) (CONTINUED)
 
Securities Transactions -- Securities transactions are accounted for on the
trade date. Realized gain and loss from securities transactions are recorded on
a specific identification basis.
 
Expenses -- Expenses directly attributable to each Portfolio are charged to that
Portfolio's operations. Expenses which are applicable to all Portfolios are
allocated on a pro rata basis.
 
Use of Estimates -- The Fund's financial statements are prepared in accordance
with generally accepted accounting principles, which may require the use of
management estimates and assumptions. Actual results could differ from these
estimates.
 
Federal Income Taxes -- It is each Portfolio's policy to comply with the special
provisions of the Internal Revenue Code available to regulated investment
companies. As provided therein, in any fiscal year in which a Portfolio so
qualifies, and distributes at least 90% of its taxable net income, the Portfolio
(not the shareholders) will be relieved of federal income tax on the income
distributed. Accordingly, no provision for income taxes has been made.
 
In order to avoid imposition of the excise tax applicable to regulated
investment companies, it is also each Portfolio's intention to declare as
dividends in each calendar year at least 98% of its net investment income
(earned during the calendar year) and 98% of its net realized capital gains
(earned during the twelve months ended October 31) plus undistributed amounts
from prior years.
 
NOTE 3 -- INVESTMENT MANAGEMENT FEES AND OTHER TRANSACTIONS WITH
        AFFILIATES OF THE INVESTMENT MANAGER
Under the terms of an Investment Management Agreement with Waterhouse Asset
Management, Inc. (the "Investment Manager"), an indirect wholly owned subsidiary
of The Toronto-Dominion Bank, for the investment management services furnished
to each Portfolio, such Portfolio pays the Investment Manager an annual
investment management fee, on a graduated basis, equal to .35 of 1% of the first
$1 billion of average daily net assets of each such Portfolio, .34 of 1% of the
next $1 billion, and .33 of 1% of average daily net assets of each such
Portfolio over $2 billion. The Investment Manager has agreed to waive a portion
of its fee payable by the Municipal Portfolio through October 15, 1998, so that
the actual fee payable annually by the Portfolio during the period will be equal
to .25 of 1% of its average daily net assets. For the six months ended April 30,
1998, the Investment Manager voluntarily waived $144,647 of its investment
management fee for the Municipal Portfolio.
 
Waterhouse Securities, an affiliate of the Investment Manager, has been retained
under an Administration Agreement to perform certain administrative services for
the Fund. For the administrative services rendered to the Fund, each Portfolio
pays Waterhouse Securities a monthly fee at an annual rate of .10 of 1% of each
Portfolio's average daily net assets. For the six months ended April 30, 1998,
the Investment Manager voluntarily waived $1,788 of its adminstration fee for
the Municipal Portfolio.
 
Waterhouse Securities has been retained under a Shareholder Services Agreement
to perform certain shareholder services necessary for the operation of the Fund.
The shareholder service plan adopted by the Fund provides that each Portfolio
pays Waterhouse Securities a monthly fee at an annual rate of up to .25 of 1% of
average daily net assets. The Fund's Board of Directors has determined to limit
the annual fee payable through October 15, 1998 under the Shareholder Servicing
Plan so as not to exceed .20 of 1% of average daily net assets in the case of
the Money Market Portfolio, .17 of 1% of average daily net assets in the case of
the U.S. Government Portfolio, and .11 of 1% of average daily net assets in the
case of the Municipal Portfolio. For the six months ended April 30, 1998,
Waterhouse Securities voluntarily waived $1,448,592, $178,990, and $7,500 of its
shareholder servicing fee for the Money Market Portfolio, the U.S. Government
Portfolio, and the Municipal Portfolio, respectively.

                   WATERHOUSE INVESTORS CASH MANAGEMENT FUNDS
    NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 1998 (UNAUDITED) (CONTINUED)
 
The Fund has entered into a Transfer Agency and Dividend Disbursing Agency
Agreement with Waterhouse National Bank (the "Bank"), an affiliate of the
Investment Manager, to perform transfer and dividend disbursing agency-related
services. For such services, each Portfolio pays the Bank a monthly fee at an
annual rate of .20 of 1% of average daily net assets. For the six months ended
April 30, 1998, the Bank voluntarily waived $50,655 and $13,551 of its transfer
agent fee for the Money Market Portfolio and the Municipal Portfolio,
respectively.
 
Each Director who is not an "interested person" ("disinterested Director") as
defined in the Act receives from the Fund a base annual retainer of $12,000,
payable quarterly. Each disinterested Director who serves on the Board of
Directors of the "Fund Complex" (which includes the Fund and National Investors
Cash Management Fund, Inc.), receives a supplemental annual retainer of $5,000,
payable quarterly.
 
Additionally, each disinterested Director of the Fund receives from the Fund a
fee of $2,000 for each meeting attended. In the event that meetings of the Fund
Complex are held on the same day or concurrently, such meetings are considered a
single meeting and the meeting fee is paid by the Fund Complex.
 
NOTE 4 -- FEDERAL TAX INFORMATION
In accordance with the Federal tax requirements, the Municipal Portfolio
designates substantially all the dividends paid from net investment income
during the six months ended April 30, 1998 as "exempt-interest dividends." As
required by Federal regulations, shareholders will receive notification of their
portion of the Fund's taxable ordinary dividends and capital gains distributions
paid (if any) for the 1998 calendar year early in 1999.

                          April 30, 1998 (Unaudited)


(A)  Variable rate securities. The rates shown are the current rates on April
     30, 1998. Dates shown represent the next interest reset date.

(B)  These obligations were acquired for investment, not with intent to
     distribute or sell. They are restricted as to public resale. These
     obligations were acquired at a cost of par. On April 30, 1998, the
     aggregate value of these securities, valued at amortized cost, is 
     $135,960,494, representing 5.8% of net assets of the Money Market
     Portfolio.

(C)  Securities payable on demand. The interest rate, which is subject to
     change, is based upon bank prime rates or an index of market rates.

(D)  Bonds which are prerefunded or escrowed to maturity are collateralized by
     U.S. Government Securities which are held in escrow and are used to pay
     principal and interest on the municipal issue and to retire the bonds in
     full at the earliest refunding date.

(E)  Security may be redeemed prior to maturity date at the discretion of the
     issuer.
