MONEY MANAGEMENT PLUS 
Prime Portfolio 
4550 Montgomery Avenue, Bethesda, Maryland 20814 

INVESTMENT OBJECTIVE AND POLICIES 

   
MONEY MANAGEMENT PLUS Prime Portfolio (the "Fund") is a money market  
fund which seeks to obtain the highest level of current income,  
consistent with preservation of capital and liquidity, that is available  
through investments in specified money market instruments. The Fund's  
assets are invested in certificates of deposit of major banks, prime  
commercial paper and high-grade short-term corporate obligations, and  
short-term U.S. Government and agency securities. The investments mature  
in 13 months year or less, with an average weighted maturity of 90 days  
or less. The Fund seeks to maintain a constant net asset value of $1.00  
per share for the Fund. An investment in the Fund is neither insured nor  
guaranteed by the U.S. Government. There can be no assurance that the  
Fund will be successful in maintaining a constant net asset value of  
$1.00 per share. 

- -------------------------------------------------------------------------- 
Notwithstanding the investment objectives and policies of the Fund, it  
is currently invested almost entirely in U.S. Government securities in  
order to meet diversification requirements. Further, due to the Fund's  
relatively small asset size, its fund operating expenses are relatively  
high compared to other money market funds.  For this reason, the Fund's  
Board of Trustees has concurred with the Advisor's recommendation that  
the Fund be liquidated in the next few months.

FUND EXPENSES 

   
A.  Shareholder Transaction Expenses         Prime Portfolio 
    Sales Load on Purchases                  None 
    Sales Load on Reinvested Dividends       None 
    Deferred Sales Load                      None 
    Redemption Fees                          None 
    Exchange Fee                             None 


B.  Annual Fund Operating Expenses (as a  
    percentage of average net assets) 
    Management Fees                          0.50% 
    Rule 12b-1 Fees                          0.35% 
    Other Expenses                           0.62% 
    Total Fund Operating Expenses            1.47% 


C. Example:       You would pay the following expenses on a $1,000  
investment, assuming (1) 5% annual return;(2) redemption at the end of  
each period: 

                           1 Year           3 Years  5 Years  10 Years 
                           $15              $46      $80      $176 
    
The example, which is hypothetical, should not be considered a  
representation of past or future expenses. Actual expenses may be higher  
or lower than those shown. 

Explanation of Table: The purpose of the table is to assist you in  
understanding the various costs and expenses that an investor in the  
Fund may bear directly (shareholder transaction costs) or indirectly  
(annual fund operating expenses). 

      A.  Shareholder Transaction Expenses are charges you pay when you  
buy or sell shares of the Funds. If you request a wire redemption of  
less than $1,000, you will be charged a $5 wire fee. 

   
      B.  Annual Fund Operating Expenses are based on the Fund's  
historical expenses, although Management Fees have been restated to  
reflect expenses anticipated in the current fiscal year. Management Fees  
are paid by the Fund to Calvert Asset Management Company, Inc.  
("Advisor") for managing its investments and business affairs. The Fund  
incurs Other Expenses for maintaining shareholder records, furnishing  
shareholder statements and reports, and other services. If Management  
had not reimbursed or waived fees, the current Other Expenses and Total  
Fund Operating Expenses for would have been 0.56% and 1.41%,  
respectively. Management Fees and Other Expenses have already been  
reflected in the Fund's yield and are not charged directly to individual  
shareholder accounts. Please refer to the section "Management of the  
Fund" for further information. 

          The Fund's Rule 12b-1 fees include an asset-based sales charge.  
Thus, long-term shareholders in the Fund could pay more than the  
economic equivalent of the maximum front-end sales charge permitted by  
rules of the National Association of Securities Dealers, Inc.; however,  
this is unlikely because these are money market funds, and have no  
front-end sales charge. 
    


FINANCIAL HIGHLIGHTS 

   
The following table provides information about the Fund's financial  
history. It expresses the information in terms of a single share  
outstanding throughout each period. The table has been audited by those  
independent accountants whose reports are included in the respective  
Annual Reports to Shareholders. The table should be read in conjunction  
with the financial statements and their related notes. The current  
Annual Report to Shareholders is incorporated by reference into the  
Statement of Additional Information.

INVESTMENT OBJECTIVE AND POLICIES 

Investment Objective: The Fund seeks to earn the highest level of  
current income, consistent with preservation of capital and liquidity. 

   
Money Management Plus Prime Portfolio is a diversified money market  
fund. Its objective is to earn the highest level of current income,  
consistent with preservation of capital and liquidity, that is available  
through investment in specified money market instruments. The Fund's  
assets are invested in securities maturing in 13 months or less, and it  
maintains an average weighted maturity of 90 days or less. 
    

Prime Portfolio invests primarily in CDs, prime commercial paper, and  
U.S. Government Obligations. 

   
Prime Portfolio invests in certificates of deposit and other obligations  
of banks having total assets of at least $1 billion, prime commercial  
paper and high grade (Aaa or Aa rated or equivalent quality) short-term  
corporate obligations, including participation interests in loans  
extended to issuers of such obligations, and obligations of the U.S.  
Government, its agencies and instrumentalities. Such securities may be  
purchased subject to repurchase agreements with recognized securities  
dealers and banks. The Fund may invest more than 25% of its assets in  
obligations of banks. See the Statement of Additional Information,  
"Appendix, Commercial Paper and Bond Ratings." Also, the Fund may invest  
in high-quality, U.S. dollar-denominated international money market  
instruments, and up to 5% of its assets in reverse repurchase agreements. 
    

U.S. Government Obligations 

Obligations issued by the U.S. Treasury, such as U.S. Treasury bills,  
notes and bonds, are supported by the full faith and credit of the U.S.  
Government. 

Certain obligations issued or guaranteed by a U.S. Government agency or  
instrumentality are supported by the full faith and credit of the U.S.  
Government. These include obligations issued by the Export-Import Bank,  
Farmers Home Administration, Government National Mortgage Association,  
Postal Service, Merchant Marine, and Washington Metropolitan Area  
Transit Authority. 

   
The Fund may also invest in other U.S. Government agency or  
instrumentality obligations which are supported only by the credit of  
the agency or instrumentality and may be further supported by the right  
of the issuer to borrow from the U.S. Treasury. 
    

Repurchase Agreements 

   
The Fund may enter into repurchase agreements. In a repurchase  
agreement, the Fund buys a security subject to the right and obligation  
to sell it back at a higher price. These transactions must be fully  
secured at all times, but they involve some credit risk to the Fund if  
the other party defaults on its obligation and the Fund is delayed or  
prevented from liquidating the collateral. 

Reverse Repurchase Agreements 

The Fund may engage in reverse repurchase agreements. In a reverse  
repurchase agreement, the Fund sells a security subject to the right and  
obligation to buy it back at a higher price. The Fund then invests the  
proceeds from the transaction in another obligation in which it is  
authorized to invest. In order to minimize any risk involved, the Fund  
maintains in a segregated account liquid assets equal in value to the  
repurchase price, and currently intends to limit its borrowing due to  
reverse repurchase agreements to only 5% of total assets. 
    

Bank CDs 

   
The Fund may also invest in certificates of deposit and other debt  
obligations of commercial banks, savings banks, and savings and loan  
associations having assets of less than $1 billion, provided that the  
principal amount of such certificate is insured in full by the Federal  
Deposit Insurance Corporation ("FDIC"). The FDIC presently insures  
accounts up to $100,000; interest earned above $100,000 is not insured  
by the FDIC. 
    

When-Issued Purchases 

   
Purchasing obligations for future delivery or on a "when-issued" basis  
may increase the Fund's overall investment exposure and involves a risk  
of loss if the value of the securities declines prior to the settlement  
date. The transactions are fully secured at all times. 
    

Variable Rate Obligations 

   
The Fund may invest in variable and floating rate obligations. Variable  
rate obligations have a yield which is adjusted periodically based upon  
changes in the level of prevailing interest rates. Floating rate  
obligations have an interest rate fixed to a known lending rate, such as  
the prime rate, and are automatically adjusted when that rate changes.  
Variable and floating rate obligations lessen the capital fluctuations  
usually inherent in fixed income investments, to diminish the risk of  
capital depreciation of Fund investments and Fund shares; but this also  
means that should interest rates decline, the yield of the Fund will  
decline and the Fund would not have as many opportunities for capital  
appreciation of Fund investments. 
    

Demand Notes and Temporary Investments 

   
The Fund may invest in floating rate and variable rate demand notes.  
Demand notes provide that the holder may demand payment of the note at  
its par value plus accrued interest by giving notice to the issuer. To  
ensure the ability of the issuer to make payment upon such demand, the  
note may be supported by an unconditional bank letter of credit. 

The Fund may invest in structured money market instruments. In all  
cases, the Fund may invest in structured money market instruments. In  
all cases, it invests only in high-quality instruments (rated in one of  
the two highest rating categories, or if unrated, of comparable credit  
quality) that meet the requirements of SEC Rule 2a-7 regarding credit  
quality and maturity. See the Statement of Additional Information. 
    

Other Policies 

   
The Fund has adopted certain fundamental investment restrictions which  
are discussed in detail in the Statement of Additional Information.  
Unless specifically noted otherwise, the investment objective, policies  
and restrictions of the Fund are fundamental and may not be changed  
without shareholder approval. There can be no assurance that the Fund  
will be successful in meeting its investment objective. 
    

YIELD 

Yield refers to income generated by an investment over a period of time. 

   
From time to time, the Fund may advertise "yield" and "effective yield."  
Yield figures are based on historical earnings and are not intended to  
indicate future performance. The "yield" refers to the actual income  
generated by an investment in the Fund over a particular base period,  
stated in the advertisement. If the base period is less than one year,  
the yield will be "annualized." That is, the amount of income generated  
by the investment during the base period is assumed to be generated over  
a one-year period and is shown as a percentage of the investment. The  
"effective yield" is calculated similarly, but, when annualized, the  
income earned by an investment in the Fund is assumed to be reinvested.  
The "effective yield" will be slightly higher than the "yield" because  
of the compounding effect of this assumed reinvestment. 
    

MANAGEMENT OF THE FUND 

The Board of Trustees supervises the activities and reviews its  
contracts with companies that provide the Fund with services. 

   
The Fund is the only series of Calvert Cash Reserves, a Massachusetts  
business trust organized on March 16, 1982, now doing business as Money  
Management Plus. In October, 1992, Prime Portfolio began offering a  
second class of shares, the CCR Prime Shares, which was discontinued  
during 1994. 

The Fund is an open-end diversified management investment company. The  
Fund is not required to hold annual shareholder meetings, but special  
meetings may be called for certain purposes such as electing Trustees,  
changing fundamental policies, or approving a management contract. As a  
shareholder, you receive one vote for each share you own. 
    

Calvert Group is one of the largest investment management firms in the  
Washington, D.C. area. 

   
Calvert Group, Ltd., parent of the Funds' investment advisor, transfer  
agent, and distributor, is a subsidiary of Acacia Mutual Life Insurance  
Company of Washington, D.C. Calvert Group is one of the largest  
investment management firms in the Washington, D.C. area. Calvert Group,  
Ltd. and its subsidiaries are located at 4550 Montgomery Avenue, Suite  
1000N, Bethesda, Maryland 20814. As of December 31, 1995, Calvert Group  
managed and administered assets in excess of $4.8 billion and more than  
200,000 shareholder and depositor accounts. 

Calvert Asset Management serves as Advisor to the Funds. 

Calvert Asset Management Company, Inc. (the "Advisor") is the Fund's  
investment advisor. The Advisor provides the Fund with investment  
supervision and management; administrative services and office space;  
furnishes executive and other personnel to the Fund; and pays the  
salaries and fees of all Trustees who are affiliated persons of the  
Advisor. The Advisor may also assume and pay certain advertising and  
promotional expenses of the Fund and reserves the right to compensate  
broker-dealers in return for their promotional or administrative  
services. The Advisor has agreed to limit the Fund's expenses to the  
most restrictive state limitation in effect. 

The Advisor receives a fee based on a percentage of the Fund's assets. 

Pursuant to the Investment Advisory Agreement, the Advisor is entitled  
to, and did receive for fiscal 1995, an annual advisory fee of 0.50% of  
the Fund's respective average daily net assets. 

Calvert Distributors, Inc. serves as underwriter to market the Fund's  
shares. 

Calvert Distributors, Inc. ("CDI") is the Funds' principal underwriter  
and distributor. Under the terms of its underwriting agreement with the  
Funds, CDI markets and distributes the Fund's shares and is responsible  
for payment of compensation and service fees to broker-dealers, banks,  
and financial services firms, preparation of advertising and sales  
literature, and printing and mailing of prospectuses to prospective  
investors. 

The Fund may pay distribution and servicing expenses pursuant to their  
Distribution Plan. 

Pursuant to Rule 12b-1 under the Investment Company Act of 1940, the  
Fund has adopted a Distribution Plan which permits it to pay certain  
expenses associated with the distribution of its shares. Amounts paid by  
the Fund to the Distributor under the Distribution Plan are used to pay  
dealers and other selling firms dealer-paid quarterly compensation at an  
annual rate of up to 0.40% of the average daily net assets of accounts  
the respective firms maintain in the Fund. They are also used to pay  
dealers and others, including the Distributor's salespersons who service  
accounts, service fees at an annual rate of up to 0.25% of such assets,  
and to pay CDI for its marketing and distribution expenses, preparation  
of advertising and sales literature, printing and mailing of  
prospectuses to prospective investors. The Distribution Plan expenses  
may not annually exceed 0.35% of the average daily net assets of any  
Fund. For fiscal year 1995, the Fund paid Distribution Plan expenses of  
0.35 of average daily net assets. 
    

CDI may also pay additional concessions, including non-cash promotional  
incentives, such as merchandise or trips, to dealers employing  
registered representatives who sell a minimum dollar amount of shares of  
the Fund and/or shares of other Funds underwritten by CDI. CDI may make  
expense reimbursements for special training of a dealer's registered  
representatives, advertising or equipment, or to defray the expenses of  
sales contests. CDI may receive reimbursement of eligible marketing and  
distribution expenses from the Fund's Rule 12b-1 Distribution Plan. 

   
The Distribution Plan may be terminated at any time by vote of the  
Independent Trustees or by vote of a majority of the outstanding voting  
shares of the respective Fund. 
    

The transfer agent keeps your account records. 

Calvert Shareholder Services, Inc. is the Fund's transfer, dividend  
disbursing and shareholder servicing agent.

Share Price 

   
The Fund's shares are sold without a sales charge. 

The price of one share is its "net asset value," or NAV. NAV is computed  
by adding the value of a Fund's investments plus cash and other assets,  
deducting liabilities and then dividing the result by the number of  
shares outstanding. The NAV is calculated at the close of the Fund's  
business day, which coincides with the closing of the regular session of  
the New York Stock Exchange (normally 4:00 p.m. Eastern time). The Fund  
is open for business each day the New York Stock Exchange is open. The  
Fund's securities are valued according to the "amortized cost" method,  
which is intended to stabilize the NAV at $1.00 per share. 

All purchases of Fund shares will be confirmed and credited to your  
account in full and fractional shares (rounded to the nearest 1/100 of a  
share). The Fund may send monthly statements in lieu of immediate  
confirmations of purchases and redemptions.

received by 4:00 p.m. Eastern time. 

WHEN YOUR ACCOUNT WILL BE CREDITED 

Before you buy shares, please read the following information to make  
sure your investment is accepted and credited properly. 

   
Your purchase will be processed at the net asset value calculated after  
your order is received and accepted. Except in the case of telephone  
orders, investors whose payments are received in or converted into  
federal funds by 12:30 p.m. Eastern time by the custodian will receive  
the dividend declared that day. If your wire purchase is received after  
12:30 p.m. Eastern time, your account will begin earning dividends on  
the next business day. A telephone order placed to Calvert Institutional  
Marketing Services by 12:30 p.m. Eastern time will become effective at  
the price determined at 5 p.m. Eastern time and the shares purchased  
will receive the dividend on Fund shares declared that day if federal  
funds are received by the custodian by 5 p.m. Eastern time. Exchanges  
begin earning dividends the next business day after the exchange request  
is received by mail or telephone. If the purchase is by check and is  
received by 4:00 p.m. Eastern time, it will begin earning dividends the  
next business day. 

All of your purchases must be made in U.S. dollars and checks must be  
drawn on U.S. banks. No cash will be accepted. The Fund reserves the  
right to suspend the offering of shares for a period of time or to  
reject any specific purchase order. If your check does not clear, your  
purchase will be cancelled and you will be charged a $10 fee plus costs  
incurred by the Fund. When you purchase by check or with Calvert Money  
Controller, those funds will be on hold for up to 10 business days from  
the date of receipt. During that period, redemptions against those funds  
(including drafts) will not be honored. To avoid this collection period,  
you can wire federal funds from your bank, which may charge you a fee. 
    

EXCHANGES 

   
You may exchange shares of the Fund for shares of other Calvert Group  
Funds. 
    

If your investment goals change, the Calvert Group Family of Funds has a  
variety of investment alternatives that includes common stock funds,  
tax-exempt and corporate bond funds, and money market funds. The  
exchange privilege is a convenient way to buy shares in other Calvert  
Group Funds in order to respond to changes in your goals or in market  
conditions. Before you make an exchange from a Fund or Portfolio, please  
note the following: 

         Call your broker or a Calvert representative for information  
and a prospectus for any of Calvert's other Funds registered in your  
state. Read the prospectus of the Fund or Portfolio into which you want  
to exchange for relevant information, including class offerings. 

Each exchange represents the sale of shares of one Fund and the purchase  
of shares of another. 

   
         Complete and sign an application for an account in that Fund or  
Fund, taking care to register your new account in the same name and  
taxpayer identification number as your existing Calvert account(s).  
Exchange instructions may then be given by telephone if telephone  
redemptions have been authorized and the shares are not in certificate  
form. 

         Shares on which you have already paid a sales charge at Calvert  
Group may be exchanged into another Fund at no additional charge. Shares  
acquired by reinvestment of dividends or distributions may be exchanged  
into another Fund at no additional charge. Except for money market  
funds, if you make a purchase at NAV, you may exchange that amount to  
another fund at no additional sales charge. 
    

The Fund reserves the right to terminate or modify the exchange  
privilege with 60 days' written notice. 

OTHER CALVERT GROUP SERVICES 

Calvert Information Network 

24 hour performance and prices 

Calvert Group has a round-the-clock telephone service that lets existing  
customers use a push button phone to obtain prices, performance  
information, and account balances. Complete instructions for this  
service may be found on the back of each statement. 

Calvert Money Controller 

Calvert Money Controller eliminates the delay of mailing a check or the  
expense of wiring funds. You can request this free service on your  
application. 

This service allows you to authorize electronic transfers of money to  
purchase or sell shares. You use Calvert Money Controller like an  
"electronic check" to move money ($50 to $300,000) between your bank  
account and your Calvert Group account with one phone call. Allow one or  
two business days after the call for the transfer to take place; for  
money recently invested, allow normal check clearing time (up to 10  
business days) before redemption proceeds are sent to your bank. 

You may also arrange systematic monthly or quarterly investments  
(minimum $50) into your Calvert Group account. After you give us proper  
authorization, your bank account will be debited to purchase Fund  
shares. A debit entry will appear on your bank statement. If you would  
like to make arrangements for systematic monthly or quarterly  
redemptions from your Calvert Group account, call your broker or Calvert  
for a Money Controller Application. 

Telephone Transactions 

Calvert may record all telephone calls. 

If you have telephone transaction privileges, you may purchase, redeem,  
or exchange shares, wire funds and use Calvert Money Controller by  
telephone. You automatically have telephone privileges unless you elect  
otherwise. The Fund, the transfer agent and their affiliates are not  
liable for acting in good faith on telephone instructions relating to  
your account, so long as they follow reasonable procedures to determine  
that the telephone instructions are genuine. Such procedures may include  
recording the telephone calls and requiring some form of personal  
identification. You should verify the accuracy of telephone transactions  
immediately upon receipt of your confirmation statement. 

   
Complete the account application for the easiest way to establish  
services. 
    

The easiest way to establish optional services on your Calvert Group  
account is to select the options you desire when you complete your  
account application. If you wish to add other options later, you may  
have to provide us with additional information and a signature  
guarantee. Please call your broker or Calvert Investor Relations at  
800-368-2745 for further assistance. For our mutual protection, we may  
require a signature guarantee on certain written transaction requests. A  
signature guarantee verifies the authenticity of your signature, and may  
be obtained from any bank, savings and loan association, credit union,  
trust company, broker-dealer firm or member of a domestic stock  
exchange. A signature guarantee cannot be provided by a notary public. 

Householding of General Mailings 

   
Householding reduces Fund expenses and saves paper and trees for the  
environment. 
    

If you have multiple accounts with Calvert, you may receive combined  
mailings of some shareholder information, such as semi-annual and annual  
reports. Please contact Calvert Investor Relations at 800-368-2745 to  
receive additional copies of information. 

Special Services and Charges 

The Fund pays for shareholder services but not for special services that  
are required by a few shareholders, such as a request for a historical  
transcript of an account. You may be required to pay a research fee for  
these special services. 

If you are purchasing shares of the Fund through a program of services  
offered by a securities dealer or financial institution, you should read  
the program materials in conjunction with this Prospectus. Certain  
features of the Fund may be modified in these programs, and  
administrative charges may be imposed by the broker-dealer for the  
services rendered. 

Tax-Saving Retirement Plans 

   
Contact Calvert Group for complete information kits discussing the  
plans, and their benefits, provisions and fees. 
    

Calvert Group can set up your new account under one of several  
tax-deferred plans. These plans let you invest for retirement and  
shelter your investment income from current taxes. Minimums may differ  
from those listed in the chart on page 22. 

         Individual retirement accounts (IRAs): available to anyone who  
has earned income. You may also be able to make investments in the name  
of your spouse, if your spouse has no earned income. 

         Qualified Profit-Sharing and Money-Purchase Plans (including  
401(k) Plans): available to self-employed people and their partners, or  
to corporations and their employees. 

         Simplified Employee Pension Plan (SEP-IRA): available to  
self-employed people and their partners, or to corporations. Salary  
reduction pension plans (SAR-SEP IRAs) are also available to employers  
with 25 or fewer employees. 

         403(b)(7) Custodial Accounts: available to employees of most  
non-profit organizations and public schools and universities. 

Consolidated Asset Account ("CAA") 

   
Certain brokerage firms may offer their customers CAA, a special cash  
management service linked to one of the Fund's Funds. CAA customers may  
have free-credit cash balances at their brokerage firm account  
automatically invested in Fund shares on a daily basis. Participating  
brokerage firms will charge their customers a fee for the CAA program  
and may establish a higher minimum balance. Details of CAA, including  
the fee charged, are available from participating brokerage firms. This  
prospectus should be read together with such firm's materials regarding  
these fees and services. 
    

SELLING YOUR SHARES 

You may redeem all or a portion of your shares on any business day. Your  
shares will be redeemed at the next net asset value calculated after  
your redemption request is received and accepted. See the chart below  
for specific requirements necessary to make sure your redemption request  
is acceptable. Remember that the Fund may hold payment on the redemption  
of your shares until it is reasonably satisfied that investments made by  
check or by Calvert Money Controller have been collected (normally up to  
10 business days). 

Redemption Requirements To Remember 


To ensure acceptance of your redemption 
request, please follow the procedures described here and below. 


   
Once your shares are redeemed, the proceeds will normally be sent to you  
on the next business day, but if making immediate payment could  
adversely affect the Fund, it may take up to seven (7) days. Calvert  
Money Controller redemptions generally will be credited to your bank  
account on the second business day after your phone call. When the New  
York Stock Exchange is closed (or when trading is restricted) for any  
reason other than its customary weekend or holiday closings, or under  
any emergency circumstances as determined by the Securities and Exchange  
Commission, redemptions may be suspended or payment dates postponed. 

If you sell shares by telephone or written request, you will receive  
dividends through the date the request is received and processed. If you  
write a draft to sell shares, the shares will earn dividends until the  
draft is presented to the Fund to be paid. 

Minimum account balance is $1,000 

Please maintain a balance in your account of at least $1,000. If, due to  
redemptions, the account falls below $1,000, or you fail to invest at  
least $1,000, it may be closed and the proceeds mailed to you at the  
address of record. You will be given notice that your account will be  
closed after 30 days unless you make an additional investment to  
increase your account balance to the $1,000 minimum. 
    

HOW TO SELL YOUR SHARES 

Draftwriting 

   
You may redeem shares in your account by writing a draft for at least  
$250. If you complete and return the signature card for Draftwriting,  
the Fund will mail bank drafts to you, printed with your name and  
address. Generally, there is no charge to you for the maintenance of  
this service or the clearance of drafts, but the Fund reserves the right  
to charge a service fee for drafts returned for uncollected or  
insufficient funds. The Fund will charge $25 for any stop payments on  
drafts. As a service to shareholders, the Fund may automatically  
transfer the dollar amount necessary to cover drafts you have written on  
the Fund to your Fund account from any other of your identically  
registered accounts in Calvert money market funds or Calvert Insured  
Plus. The Fund may charge a fee for this service.

                                   provide a copy of the trust

telephone and have your money mailed to your address of record or wired  
to an address or bank you have previously authorized. A charge of $5 is  
imposed on wire transfers of less than $1,000. See "Telephone  
Transactions" on page 24. 
    

Calvert Money Controller 

Please allow sufficient time for Calvert Group to process your initial  
request for this service (normally 10 business days). You may also  
authorize automatic fixed amount redemptions by Calvert Money  
Controller. All requests must be received by 4:00 p.m. Eastern time.  
Accounts cannot be closed by this service. 

Exchange to Another Calvert Group Fund 

   
You must meet the minimum investment requirement of the other Calvert  
Group Fund or Fund. You can only exchange between accounts with  
identical names, addresses and taxpayer identification number, unless  
previously authorized with a signature-guaranteed letter. 
    

Systematic Check Redemptions 

   
If you maintain an account with a balance of $10,000 or more, you may  
have up to two (2) regular redemption checks for a fixed amount sent to  
you on the 15th of each month, simply by sending a letter with all  
information, including your account number, and the dollar amount ($100  
minimum). If you would like a regular check mailed to another person or  
place, your letter must be signature guaranteed. 
    

Through your Broker 

If your account is held in your broker's name ("street name"), you  
should contact your broker directly to transfer, exchange or redeem  
shares. 

DIVIDENDS AND TAXES 

   
Each year, the Fund distributes substantially all of its net investment  
income to shareholders. 
    

Dividends from the Fund's net investment income are declared daily and  
paid monthly. Net investment income consists of interest income, net  
short-term capital gains, if any, and dividends declared and paid on  
investments, less expenses. 

Dividend payment options 

   
Dividends and any distributions are automatically reinvested in  
additional shares of the same Fund, unless you elect to have the  
dividends of $10 or more paid in cash (by check or by Calvert Money  
Controller). Dividends and distributions from the Funds may be invested  
in shares of any other Calvert Group Fund or Fund with no additional  
sales charge. You must notify the Fund in writing to change your payment  
options. If you elect to have dividends and/or distributions paid in  
cash, and the U.S. Postal Service cannot deliver the check, or if it  
remains uncashed for six months, it, as well as future dividends and  
distributions, will be reinvested in additional shares. 
    

Federal Taxes 

   
In January, the Fund will mail you Form 1099-DIV indicating the federal  
tax status of dividends and any capital gain distributions paid to you  
by the Fund during the past year. Dividends and distributions are  
taxable to you regardless of whether they are taken in cash or  
reinvested. Dividends, including short-term capital gains, are taxable  
as ordinary income. Distributions from long-term capital gains are  
taxable as long-term capital gains, regardless of how long you have  
owned Fund shares. A portion of the Fund's dividends may qualify for the  
dividends received deduction for corporations. 
    

Other Tax Information 

In addition to federal taxes, you may be subject to state or local taxes  
on your investment, depending on the laws in your area. You will be  
notified to the extent, if any, that dividends reflect interest received  
from U.S. government securities. Such dividends may be exempt from  
certain state income taxes. 

Taxpayer Identification Number 

   
If we do not have your correct Social Security or Taxpayer  
Identification Number ("TIN") and a signed certified application or Form  
W-9, Federal law requires the Fund to withhold 31% of your dividends. In  
addition, you may be subject to a fine. You will also be prohibited from  
opening another account by exchange. If this TIN information is not  
received within 60 days after your account is established, your account  
may be redeemed at the current NAV on the date of redemption. The Fund  
reserves the right to reject any new account or any purchase order for  
failure to supply a certified TIN.

========================================================================== 
                    INVESTMENT OBJECTIVE AND POLICIES 
========================================================================== 

         Money  Management  Plus Prime  Portfolio  (the "Fund") is a money 
market  fund which seeks to obtain the  highest  level of current  income, 
consistent  with safety,  preservation  of capital and liquidity,  that is 
available  through  investment  in  specified  money  market  instruments. 
Currently,  the Fund's  assets are invested in  securities  maturing in 13 
months or less and the Fund maintains an average  weighted  maturity of 90 
days or less.  Fund  investments  are valued at amortized  cost.  The Fund 
intends to  maintain a constant  net asset  value of $1.00 per share.  The 
Fund invests exclusively in short-term money market instruments. 

Prime Portfolio: The Portfolio will be invested exclusively in: 
         (1) U.S.  dollar-denominated  certificates  of deposit,  bankers' 
acceptances  and other debt  obligations  of U.S. banks and their branches 
located  outside  of the  U.S.  and of U.S.  branches  of  foreign  banks, 
provided  that the bank has total  assets of at least $1  billion  (or the 
equivalent in other  currencies)  or, if its total assets are less than $1 
billion,  the  principal  amount of such  obligation is insured in full by 
the Federal Deposit Insurance Corporation; 
         (2) commercial  paper of both domestic and foreign  issuers which 
at the date of  investment  is rated A-1 by Standard & Poor's  Corporation 
or Prime-1 by Moody's  Investors  Service,  Inc.,  or, if  unrated,  is of 
comparable  quality as determined by the Advisor under the  supervision of 
the Board of Trustees; 
         (3) short-term (one year or less)  corporate  obligations of both 
domestic and foreign  issuers  which at the date of  investment  are rated 
AAA or AA by  Standard  & Poor's or Aaa or Aa by Moody's  or, if  unrated, 
are  of  comparable  quality  as  determined  by  the  Advisor  under  the 
supervision of the Board of Trustees; 
         (4)  obligations   issued  or  guaranteed  as  to  principal  and 
interest by the U.S. Government,  its agencies and  instrumentalities,  or 
by  foreign  governments,  their  agencies  and  instrumentalities,  or by 
international agencies and instrumentalities; and 
         (5)  such  obligations  subject  to  repurchase  agreements  with 
recognized securities dealers and banks. 

         While  the Fund  invests  only in  high-grade,  short-term  money 
market  instruments,  there can be, of course,  no assurance that the Fund 
will be successful in meeting its  investment  objective or in maintaining 
a constant net asset value of $1.00 per share  because  there are inherent 
risks in the ownership of any  investment.  An increase in interest  rates 
will  generally  reduce  the value of Fund  investments,  and a decline in 
interest  rates will  generally  increase  the value of Fund  investments. 
Investments  in  obligations  not  guaranteed by the full faith and credit 
of the U.S.  Government  are  subject to the ability of the issuer to make 
payment  at  maturity.  Dividends  paid  by the  Fund  will  fluctuate  as 
interest  rates  and  net  investment  income  fluctuate.  The  Fund  will 
attempt,  through careful management and diversification,  to reduce these 
risks and enhance the  opportunities  for higher  income and greater price 
stability. 

Repurchase Agreements 
         The Fund  engages  in  repurchase  agreements  in order to earn a 
higher  rate of  return  than it could  earn  simply by  investing  in the 
obligation  which is the subject of the repurchase  agreement.  Repurchase 
agreements are not, however, without risk. 
         In the event of the  bankruptcy  of a seller during the term of a 
repurchase  agreement,  a legal  question  exists as to  whether  the Fund 
would be deemed the owner of the  underlying  security  or would be deemed 
only to have a  security  interest  in and lien  upon such  security.  The 
Fund  will  only  engage  in   repurchase   agreements   with   recognized 
securities  dealers and banks  determined to present  minimal  credit risk 
by the Advisor  under the direction  and  supervision  of the Fund's Board 
of  Trustees.  Repurchase  agreements  are always for periods of less than 
one  year  and no more  than 10% of a Fund's  assets  may be  invested  in 
repurchase agreements not terminable within seven days. 
         In addition,  the Fund will only engage in repurchase  agreements 
reasonably  designed to secure fully during the term of the  agreement the 
seller's  obligation  to  repurchase  the  underlying  security  and  will 
monitor the market  value of the  underlying  security  during the term of 
the  agreement.  If the value of the underlying  security  declines and is 
not at least equal to the  repurchase  price due the Fund  pursuant to the 
agreement,   the  Fund  will  require  the  seller  to  pledge  additional 
securities  or cash to secure the  seller's  obligations  pursuant  to the 
agreement.  If the seller  defaults on its  obligation to  repurchase  and 
the value of the underlying  security declines,  the Fund may incur a loss 
and may incur expenses in selling the underlying security. 

Reverse Repurchase Agreements 
         The  Fund may  also  engage  in  reverse  repurchase  agreements. 
Under a reverse repurchase  agreement,  the Fund sells its securities to a 
bank or securities  dealer and agrees to repurchase  those securities from 
such party at an agreed  upon date and price  reflecting  a market rate of 
interest.  The Fund  invests the  proceeds  from each  reverse  repurchase 
agreement in  obligations  in which it is authorized  to invest.  The Fund 
intends  to  enter  into a  reverse  repurchase  agreement  only  when the 
interest  income  provided for in the obligation in which the Fund invests 
the  proceeds  is  expected  to  exceed  the  amount  the Fund will pay in 
interest to the other party to the  agreement,  plus all costs  associated 
with the  transactions.  The Fund does not intend to borrow  for  leverage 
purposes.  The Fund will only be permitted to pledge  assets to the extent 
necessary to secure borrowings and reverse repurchase agreements. 
         During the time a reverse  repurchase  agreement is  outstanding, 
the Fund will  maintain  in a  segregated  custodial  account an amount of 
cash,  U.S.  Government  securities  or other  liquid,  high-quality  debt 
securities  equal in value to the repurchase  price. The Fund will mark to 
market  the  value of  assets  held in the  segregated  account,  and will 
place  additional  assets in the account  whenever  the total value of the 
account falls below the amount required under applicable regulations. 
         The Fund's  use of reverse  repurchase  agreements  involves  the 
risk  that the other  party to the  agreements  could  become  subject  to 
bankruptcy or  liquidation  proceedings  during the period the  agreements 
are  outstanding.  In such event,  the Fund may not be able to  repurchase 
the   securities   it  has  sold  to  that  other   party.   Under   those 
circumstances,  if at the expiration of the agreement such  securities are 
of  greater  value  than  the  proceeds  obtained  by the Fund  under  the 
agreements,  the Fund may have been  better  off had it not  entered  into 
the  agreement.  However,  the Fund will  enter  into  reverse  repurchase 
agreements  only  with  banks  and  dealers  which  the  Advisor  believes 
present  minimal  credit  risks  under  guidelines  adopted  by the Fund's 
Board of Trustees.  In  addition,  the Fund bears the risk that the market 
value  of  the  securities   sold  by  the  Fund  may  decline  below  the 
agreed-upon  repurchase  price,  in which case the dealer may  request the 
Fund to post additional collateral. 

International Money Market Instruments 
         The Fund may  invest in U.S.  dollar-denominated  obligations  of 
foreign  branches of U.S. banks and U.S.  branches of foreign banks ("bank 
obligations.").  Such  bank  obligations  may  be  subject  to  risks  not 
associated  with  domestically  insured  bank  obligations.  For  example, 
foreign and domestic bank reserve requirements may differ. 
         The  Fund  may  also  invest  in  commercial  paper,   short-term 
corporate  obligations,  and  obligations  issued or guaranteed by foreign 
governments,  their agencies and  instrumentalities,  or by  international 
agencies  and  instrumentalities,  so long as such  instruments  are  U.S. 
dollar-denominated   and   meet   the   same   credit,    liquidity,   and 
concentration requirements as domestic obligations. 
         The bank  obligations  and  other  money  market  instruments  of 
foreign issuers  described above are subject to certain  additional risks. 
Payment  of  interest  and  principal  upon  these   obligations  and  the 
marketability  and liquidity of such  obligations in the secondary  market 
may also be adversely  affected by  governmental  action in the country of 
domicile  of the  branch  (generally  referred  to as  "sovereign  risk"). 
Examples of  governmental  actions would be the  imposition of exchange or 
currency controls,  interest  limitations or withholding taxes on interest 
income,  seizure of assets,  or the  declaration  of a  moratorium  on the 
payment of principal or interest.  In addition,  evidences of ownership of 
Fund  securities  may be held  outside  of the  U.S.,  and the Fund may be 
subject  to the  risks  associated  with  the  holding  of  such  property 
overseas. 
         These  instruments  are not  subject  to  currency  fluctuations, 
since they are  denominated  in U.S.  dollars.  The Advisor will  consider 
the  political  and  economic  conditions  in a country,  the  location of 
custody,  and the liquidity in selecting  such  instruments  for the Fund. 
Also, as an operating  policy,  it will only invest in bank obligations of 
foreign  branches  of  U.S.  banks  if the  parent  banks  guarantees  the 
obligation,  and where the  parent  bank  either has assets of at least $1 
billion  (or  equivalent  in other  currencies),  or is insured in full by 
the Federal Deposit Insurance Corporation. 

Obligations with Puts Attached 
         The Fund has  authority to purchase  securities  at a price which 
would result in a yield to maturity lower than that  generally  offered by 
the seller at the time of  purchase  when it can  acquire at the same time 
the right to sell the  securities  back to the  seller  at an agreed  upon 
price at any time  during a stated  period  or on a certain  date.  Such a 
right is generally denoted as a "put." 
         A  Fund  may  not   acquire   obligations   subject  to  puts  if 
immediately  thereafter,  with respect to 75% of the total  amortized cost 
value of its  assets,  that Fund  would  have  more than 5% of its  assets 
invested in securities  underlying puts from the same institution.  A Fund 
may,  however,  invest up to 10% of its  assets in  securities  underlying 
unconditional  puts  from the  same  institution.  Unconditional  puts are 
readily  exercisable  in the event of a default in payment of principal or 
interest  on the  underlying  securities.  The Fund  must  limit  its Fund 
investments,   including   puts,  to   instruments   of  high  quality  as 
determined by a nationally recognized statistical rating organization. 


When-Issued Purchases 
         Securities  purchased on a when-issued  basis and the  securities 
held in the Fund are  subject to changes  in market  value  based upon the 
public's  perception of the  creditworthiness of the issuer and changes in 
the  level  of  interest  rates  (which  will  generally  result  in  both 
changing in value in the same way, i.e.,  both  experiencing  appreciation 
when interest  rates decline and  depreciation  when interest rates rise). 
Therefore,  if in  order  to  achieve  higher  interest  income,  the Fund 
remains  substantially  fully  invested  at  the  same  time  that  it has 
purchased  securities  on a  when-issued  basis,  there  will be a greater 
possibility  that the market value of the Fund's  assets may vary.  No new 
when-issued  commitments  will be made by a Fund if more  than 50% of that 
Fund's net assets would become so committed. 
         When the time comes to pay for when-issued  securities,  the Fund 
will  meet  its  obligations  from  then  available  cash  flow,  sale  of 
securities or,  although it would not normally  expect to do so, from sale 
of the when-issued  securities  themselves  (which may have a market value 
greater or less than the Fund's  payment  obligation).  Sale of securities 
to meet  such  obligations  carries  with it a greater  potential  for the 
realization  of capital  losses  and  capital  gains  which are not exempt 
from federal income tax.

                         INVESTMENT RESTRICTIONS 
========================================================================== 

Fundamental 
         The   foregoing   investment   objective  and  policies  and  the 
following  investment  restrictions  and  fundamental  policies may not be 
changed  without  the  consent of the  holders of a majority of the Fund's 
outstanding  shares,  including  a  majority  of the  shares  of the Fund. 
Shares have equal  rights as to voting,  except that only shares of a Fund 
are  entitled  to vote on  matters  affecting  only  that  Fund  (such  as 
changes in investment  objective,  policies or  restrictions).  A majority 
of the shares means the lesser of (i) 67% of the shares  represented  at a 
meeting at which more than 50% of the  outstanding  shares are represented 
or (ii) more than 50% of the outstanding shares. No Fund of the Fund may: 
                  (1) Purchase common stocks,  preferred  stocks, 
         warrants, or other equity securities; 
                  (2) Sell securities short,  purchase securities 
         on  margin,  or  write  put or call  options.  The  Fund 
         reserves the right,  without percentage  limitation,  to 
         purchase    securities    with   puts   attached.    See 
         "Obligations with Puts Attached"; 
                  (3)  Issue  senior  securities,  borrow  money, 
         except from banks for  temporary or  emergency  purposes 
         and then  only in an  amount  up to 10% of the  value of 
         that  Fund's  total  assets,  and,  for The  Fund  only, 
         except by  engaging  in reverse  repurchase  agreements; 
         provided,  however,  that The Fund may engage in reverse 
         repurchase  agreements so long as, at the time it enters 
         into  a  reverse  repurchase  agreement,  the  aggregate 
         proceeds    from    outstanding    reverse    repurchase 
         agreements,  when added to other outstanding  borrowings 
         permitted by this section,  do not exceed 33 1/3% of the 
         Fund's total  assets.  In order to secure any  permitted 
         borrowings  and, for The Fund only,  reverse  repurchase 
         agreements  under  this  section,  the Fund may  pledge, 
         mortgage or hypothecate its assets.  
                  (4)   Underwrite   the   securities   of  other 
         issuers,  except to the extent  that  either the sale of 
         restricted  securities  or  the  purchase  of  municipal 
         obligations  in  accordance  with the Fund's  investment 
         objective  and  policies,   either   directly  from  the 
         issuer,  or from an  underwriter  for an issuer,  may be 
         deemed an underwriting; 
                  (5) Purchase or sell real  estate,  real estate 
         investment  trust  securities,  commodities or commodity 
         contracts, or oil and gas interests,  but this shall not 
         prevent the  Tax-Free  Fund from  investing in municipal 
         obligations  secured by real estate or interests therein 
         or prevent  The Fund from  investing  (a) in  securities 
         which  are   secured  by  real  estate  or  real  estate 
         mortgages,  or (b) in the  securities  of issuers  which 
         invest or deal in commodities,  commodity futures,  oil, 
         gas,  or  other  mineral   exploration   or  development 
         programs, real estate, or real estate mortgages; 
                  (6) Purchase or retain  securities of an issuer 
         if those  trustees  of the Fund,  each of whom owns more 
         than  1/2 of 1% of the  outstanding  securities  of such 
         issuer,  together  own more than 5% of such  outstanding 
         securities; 
                  (7) Make loans to others,  except in accordance 
         with the Fund's investment objective and policies,  such 
         as the purchase of an issue of debt  securities in which 
         the  Fund  is  authorized  to  invest,  or  pursuant  to 
         contracts  providing  for the  compensation  of  service 
         providers by compensating balances; 
                  (8)  Invest in  companies  for the  purpose  of 
         exercising  control;  or invest in  securities  of other 
         investment companies,  except as they may be acquired as 
         part  of  a  merger,  consolidation  or  acquisition  of 
         assets,  or in  connection  with a  director's/trustee's 
         deferred  compensation  plan,  as  long as  there  is no 
         duplicaton of advisory fees; 
                  (9)  Invest  more than 25% of its assets in any 
         particular industry or industries,  except that the Fund 
         may invest  more than 25% of its  assets in  obligations 
         issued  or  guaranteed  by  the  U.S.  Government,   its 
         agencies or  instrumentalities.  Industrial  development 
         bonds,  where the payment of  principal  and interest is 
         the   responsibility   of  companies   within  the  same 
         industry, are grouped together as an "industry"; 
                  (10)  Invest  more  than 5% of the value of its 
         total  assets  in   securities   where  the  payment  of 
         principal  and  interest  is  the  responsibility  of  a 
         company  or  companies   with  less  than  three  years' 
         operating history. 
                  (11)  Purchase  securities of any issuer (other 
         than  obligations  of,  or  guaranteed  by,  the  United 
         States Government, its agencies or instrumentalities,  a 
         State, its political  subdivisions or  municipalities or 
         agencies  thereof) if, as a result,  (a) more than 5% of 
         the value of its total  assets  would be invested in the 
         securities  of that issuer,  or (b) more than 25% of the 
         value  of its  total  assets  would be  invested  in the 
         securities  of  issuers  in  the  same   industry.   For 
         purposes of this  restriction  regarding  The Fund only, 
         an investment in U.S. banks or U.S.  branches of foreign 
         banks is not considered an industry; 


Non-Fundamental 
                  (12)     No more  than  10% of the  Fund's  net 
         assets may be invested in illiquid securities; 
                  (13)     For     purposes     of     investment 
         restriction  number  3 above,  the  Fund has no  current 
         intention  to  allow  its   borrowings  due  to  reverse 
         repurchase agreements to exceed 5% of total assets. 

========================================================================== 
                    PURCHASE AND REDEMPTION OF SHARES 
========================================================================== 

         The Fund requires a minimum  initial  investment of $2,000 and an 
average  account  balance  of  $1,000.  Shares  will be held in book entry 
form at the Fund's transfer agent. No share certificates will be issued. 
         Shareholders  wishing  to use the draft  writing  service  should 
complete the  signature  card enclosed  with the  Investment  Application. 
This draft  writing  service  will be subject to the  customary  rules and 
regulations  governing checking accounts,  and the Fund reserves the right 
to change or suspend  the  service.  Generally,  there is no charge to you 
for the  maintenance  of this service or for the clearance of drafts,  but 
the Fund  reserves  the right to charge a service fee for drafts  returned 
for uncollected or insufficient  funds. As a service to shareholders,  the 
Fund may  automatically  transfer  the dollar  amount  necessary  to cover 
drafts  you have  written  on the Fund to your  account  from any other of 
your  identically  registered  accounts in Calvert  money  market funds or 
Calvert Insured Plus. The Fund may charge a fee for this service. 
         When a payable  through  draft is presented to the  Custodian for 
payment,  a  sufficient  number  of full and  fractional  shares  from the 
shareholder's  account to cover the  amount of the draft will be  redeemed 
at the net asset value next determined.  If there are insufficient  shares 
in  the  shareholder's   account,  the  draft  may  be  returned.   Drafts 
presented  for  payment  which  would  require  the  redemption  of shares 
purchased by check or  electronic  funds  transfer  within the previous 10 
business  days will not be  honored.  This  draft  writing  procedure  for 
redemption  enables  shareholders to receive the daily dividends  declared 
on the shares to be  redeemed  until  such time as the draft is  presented 
for payment. 
         Amounts  redeemed  by  check  redemption  may  be  mailed  to the 
investor  without charge.  Amounts of more than $50 and less than $300,000 
may be transferred  electronically  at no charge to the investor.  Amounts 
of $1,000 or more will be  transmitted  by wire without charge by the Fund 
to the investor's  account at a domestic  commercial bank that is a member 
of the Federal Reserve System or to a  correspondent  bank. A charge of $5 
is imposed on wire transfers of less than $1,000.  If the investor's  bank 
is  not  a  Federal   Reserve   System   member,   failure  of   immediate 
notification  to that bank by the  correspondent  bank  could  result in a 
delay in crediting the funds to the investor's bank account. 
         Telephone   redemption   requests   which   would   require   the 
redemption  of shares  purchased  by check or  electronic  funds  transfer 
within  the  previous  10  business  days  may not be  honored.  The  Fund 
reserves the right to modify the telephone redemption privilege. 
         Existing   shareholders   who  at  any  time   desire  to  change 
instructions  already  given  must  send a  notice  either  to the  broker 
through  which  shares were  purchased  or to the Fund with a voided check 
from the bank  account  to receive  the  redemption  proceeds.  New wiring 
instructions  may be  accompanied by a voided check in lieu of a signature 
guarantee.  If a voided check does not  accompany  the  request,  then the 
request must be signature  guaranteed  by a commercial  bank,  savings and 
loan association,  trust company,  member firm of any national  securities 
exchange,  or credit  union.  Further  documentation  may be required from 
corporations, fiduciaries, pension plans, and institutional investors. 
         The  Fund's  redemption  check  normally  will be  mailed  to the 
investor on the next  business  day  following  the date of receipt by the 
Fund of the written or telephone  redemption  request.  If the investor so 
instructs  in the  redemption  request,  the  check  will be mailed or the 
redemption  proceeds  wired to a  predesignated  account at the investor's 
bank.  Redemption  proceeds are  normally  paid in cash.  However,  at the 
sole  discretion  of the Fund,  the Fund has the right to redeem shares in 
assets other than cash for  redemption  amounts  exceeding,  in any 90-day 
period,  $250,000 or 1% of the net asset value of the Fund,  whichever  is 
less, or as allowed by law. 
         The right of  redemption  may be suspended or the date of payment 
postponed  for any  period  during  which the New York Stock  Exchange  is 
closed (other than customary weekend and holiday  closings),  when trading 
on the New York Stock Exchange is restricted,  or an emergency  exists, as 
determined  by  the  SEC,  or  if  the   Commission  has  ordered  such  a 
suspension for the  protection of  shareholders.  Redemption  proceeds are 
normally  mailed or wired the next business day after a proper  redemption 
request has been  received,  unless  redemptions  have been  suspended  or 
postponed as described above. 

========================================================================== 
                           DIVIDENDS AND TAXES 
========================================================================== 

         The Fund declares  dividends  daily and pays them monthly,  based 
on its net  investment  income.  Net  investment  income  consists  of the 
interest  income  earned on  investments  (adjusted  for  amortization  of 
original issue or market  discount or premium),  less  expenses.  Realized 
and  unrealized  gains  and  losses  are not  included  in net  investment 
income.  Net short-term  capital gains will be distributed once each year, 
although  the Fund may  distribute  them more  frequently  if necessary in 
order to  maintain  net asset value at $1.00 per share.  Distributions  of 
net capital  gains,  if any,  are  normally  declared and paid by the Fund 
once a  year;  however,  the  Fund  does  not  intend  to  make  any  such 
distributions  from securities  profits unless  available loss carryovers, 
if any, have been used or have expired. 
         Purchasers  of Fund shares  begin  receiving  dividends  from the 
date  federal  funds  are  received  by the Fund.  Purchases  by bank wire 
received by the Fund's  custodian  prior to 12:30 p.m.  Eastern time or by 
electronic funds transfer represent  immediately  available federal funds. 
Purchases  by  domestic  check  may  take up to two days to  convert  into 
federal  funds.  Shareholders  redeeming  shares by telephone,  electronic 
funds  transfer or written  request  will  receive  dividends  through the 
date that the  redemption  request  is  received;  shareholders  redeeming 
shares  by draft  will  receive  dividends  up to the date  such  draft is 
presented to the Fund for payment. 
         In 1995 the  Fund did  qualify  and in 1996 the Fund  intends  to 
qualify as a  "regulated  investment  company"  under  Subchapter M of the 
Internal Revenue Code as amended.  By so qualifying,  the Fund will not be 
subject to federal  income  taxes,  nor to the federal  excise tax imposed 
by the Tax Reform Act of 1986, to the extent that it  distributes  its net 
investment income and realized capital gains. 
         Dividends and distributions  are automatically  reinvested at net 
asset value in  additional  shares.  Shareholders  may elect to have their 
dividends  and  distributions  paid out monthly or quarterly in cash.  The 
Tax-Free   Fund's   dividends   of  net   investment   income   constitute 
exempt-interest  dividends on which shareholders are not generally subject 
to federal income tax; however,  under the Act, dividends  attributable to 
interest  on certain  private  activity  bonds must be included in federal 
alternative   minimum  taxable  income  for  the  purpose  of  determining 
liability (if any) for  individuals and for  corporations.  In the case of 
corporations,  alternative  minimum  taxable  income will also  include an 
item of tax  preference  consisting  of  one-half of the excess of pre-tax 
book income  over the  corporation's  other  federal  alternative  minimum 
taxable income,  and for this purpose all  exempt-interest  dividends will 
be  required  to  be  taken  into  account  as  book  income.  The  Fund's 
dividends  of net  investment  income  and  dividends  of  net  short-term 
capital gains,  whether taken in cash or reinvested in additional  shares, 
are  taxable to  shareholders  as  ordinary  income and do not qualify for 
the dividends received  deduction for corporations.  Net long-term capital 
gain  distributions,  if any,  will  generally be  includable as long-term 
capital  gain in the gross  income of  shareholders  who are  citizens  or 
residents of the United  States.  Whether such realized  securities  gains 
and losses are long- or  short-term  depends on the period the  securities 
are held by the Fund,  not the  period  for which  the  shareholder  holds 
shares of the Fund. 
         A  shareholder  may also be subject  to state and local  taxes on 
dividends  and   distributions   from  the  Fund.  The  Fund  will  notify 
shareholders  annually about the tax status of dividend and  distributions 
paid by the Fund and the  amount of  dividends  withheld,  if any,  during 
the  previous  year.  Many  states  do not tax  the  portion  of a  Fund's 
dividends which is derived from interest on U.S.  Government  obligations. 
State law  varies  considerably  concerning  the tax  status of  dividends 
derived  from  U.S.  Government  obligations.   Accordingly,  shareholders 
should  consult  their tax advisors  about the tax status of dividends and 
distributions from the Fund in their respective jurisdictions. 
         The   Internal   Revenue   Code   provides   that   interest   on 
indebtedness  incurred or  continued  in order to purchase or carry shares 
of  a  regulated  investment  company  which  distributes  exempt-interest 
dividends during the year is not deductible. 
         The Fund is  required to withhold  31% of any  dividends  and any 
long-term  capital gain  dividends,  paid by the Prime or Government  Fund 
if:  (a) the  shareholder's  social  security  number  or  other  taxpayer 
identification  number  ("TIN") is not provided or an obviously  incorrect 
TIN is provided:  (b) the shareholder  does not certify under penalties of 
perjury  that the TIN provided is the  shareholder's  correct TIN and that 
the  shareholder  is not  subject  to  backup  withholding  under  section 
3406(a)(1)(C) of the Internal Revenue Code because of  underreporting;  or 
(c) the Fund is  notified by the  Internal  Revenue  Service  that the TIN 
provided  by  the   shareholder  is  incorrect  or  that  there  has  been 
underreporting  of  interest or  dividends  by the  shareholder.  Affected 
shareholders  will receive  statements at least  annually  specifying  the 
amount  of   dividends   withheld.   Shareholders   exempt   from   backup 
withholding  include:  corporations;  financial  institutions;  tax exempt 
organizations;  individual  retirement  plans;  the  U.S.,  a  state,  the 
District  of  Columbia,  a  U.S.  possession,  a  foreign  government,  an 
international  organization,  or  any  political  subdivision,  agency  or 
instrumentality of any of the foregoing;  U.S.  registered  commodities or 
securities dealers;  real estate investment trusts;  registered investment 
companies;  bank  common  trust  funds;  certain  charitable  trusts;  and 
foreign  central  banks of issue.  Non-resident  aliens also are generally 
not  subject  to  backup  withholding  but,  along  with  certain  foreign 
partnerships  and  foreign   corporations,   may  instead  be  subject  to 
withholding   under   section   1441  of  the   Internal   Revenue   Code. 
Shareholders  claiming  exemption from backup  withholding  should call or 
write the Fund for further information. 

========================================================================== 
                           VALUATION OF SHARES 
========================================================================== 

         The net asset  value per  share,  the price at which  shares  are 
continuously  issued and  redeemed,  is computed by dividing  the value of 
the Fund's  total  assets,  less its  liabilities,  by the total number of 
shares  outstanding.  The  Fund's  net  asset  value is  determined  every 
business  day at the  close of the New  York  Stock  Exchange  (generally, 
4:00 p.m.,  Eastern  time),  and at such other times as may be appropriate 
or  necessary.  The  Funds do not  determine  net asset  value on  certain 
national  holidays  or other days on which the New York Stock  Exchange is 
closed:  New Year's Day,  Presidents'  Day,  Good  Friday,  Memorial  Day, 
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. 
         The Fund's assets,  including  commitments to purchase securities 
on a  when-issued  basis,  are valued at their  amortized  cost which does 
not take into account  unrealized  capital gains or losses.  This involves 
valuing  an  instrument  at its cost and  thereafter  assuming  a constant 
amortization  to maturity of any  discount or premium,  regardless  of the 
impact  of  fluctuating   interest  rates  on  the  market  value  of  the 
instrument.  While this method  provides  certainty in  valuation,  it may 
result in periods  during which value,  as determined  by amortized  cost, 
is higher or lower  than the price  that  would be  received  upon sale of 
the  instrument.  During periods of declining  interest  rates,  the daily 
yield on shares of a Fund may tend to be  higher  than a like  computation 
made  by  a  fund  with  identical   investments  utilizing  a  method  of 
valuation  based upon market  prices and  estimates  of market  prices for 
all of its  Fund  instruments.  Thus,  if the use of  amortized  cost by a 
Fund  resulted  in a lower  aggregate  Fund value on a  particular  day, a 
prospective  investor  in the  Fund  would be able to  obtain  a  somewhat 
higher  yield  than  would  result  from  investment  in a fund  utilizing 
solely  market  values,  and existing  investors in the Fund would receive 
less  investment  income.  The converse  would apply in a period of rising 
interest rates. 
         Rule 2a-7 under the  Investment  Company Act of 1940  permits the 
Fund to  value  its  assets  at  amortized  cost if the Fund  maintains  a 
dollar-weighted  average  maturity  of 90 days or less and only  purchases 
obligations  having  remaining  maturities of 13 months or less. Rule 2a-7 
requires,  as a  condition  of its  use,  that  the  Fund  invest  only in 
obligations  determined  by  the  Trustees  to be  of  high  quality  with 
minimal  credit  risks and further  requires  the  Trustees  to  establish 
procedures designed to stabilize,  to the extent reasonably possible,  the 
Fund's  price  per  share  as  computed  for  the  purpose  of  sales  and 
redemptions  at  $1.00.  Such  procedures  include  review  of the  Fund's 
investment  holdings by the Trustees,  at such  intervals as they may deem 
appropriate,  to determine  whether the Fund's net asset value  calculated 
by using available  market  quotations or equivalents  deviates from $1.00 
per  share.  If  such  deviation  exceeds  1/2 of 1%,  the  Trustees  will 
promptly  consider what action,  if any,  will be initiated.  In the event 
the  Trustees  determine  that a  deviation  exists  which  may  result in 
material  dilution  or other  unfair  results  to  investors  or  existing 
shareholders,  the  Trustees  will  take  such  corrective  action as they 
regard  as  necessary  and  appropriate,   including:  the  sale  of  Fund 
instruments  prior to  maturity to realize  capital  gains or losses or to 
shorten  average Fund  maturity;  the  withholding of dividends or payment 
of distributions  from capital or capital gains;  redemptions of shares in 
kind;  or the  establishment  of a net asset  value per share  based  upon 
available market quotations. 

========================================================================== 
                           CALCULATION OF YIELD 
========================================================================== 

         From time to time,  the Fund  advertises  "yield" and  "effective 
yield." Both yield  figures are based on  historical  earnings and are not 
intended  to  indicate  future  performance.  The  "yield"  refers  to the 
actual  income  generated by an  investment  in the Fund over a particular 
base  period of time.  The length  and  closing  date of the base  periods 
will be stated in the  advertisement.  If the base period is less than one 
year, the yield is then "annualized."  That is, the net change,  exclusive 
of capital  changes,  in the value of a share  during  the base  period is 
divided by the net asset value per share at the  beginning  of the period, 
and the result is  multiplied  by 365 and divided by the number of days in 
the base period.  Capital  changes  excluded from the calculation of yield 
are: (1) realized  gains and losses from the sale of  securities,  and (2) 
unrealized  appreciation and depreciation.  A Fund's "effective yield" for 
a seven-day period is its annualized  compounded  average yield during the 
period, calculated according to the following formula: 

          Effective yield = [(base period return) + 1]365/7 - 1 

         From  time to time,  the Fund may  provide,  for a given  period, 
quotations of dividend yield to  shareholders  or  prospective  investors. 
For  the  seven-day  period  ended  September  30,  1995,  the  yield  and 
effective yield were: 

                                                              Effective 
                                            Yield             Yield 

         Prime Portfolio                    3.78%             3.85%

<F1>Officers and trustees deemed to be "interested persons" of the Fund  
under the Investment Company Act of 1940, by virtue of of their  
affiliation with the Fund's Advisor.  

         Each  of  the  above   directors/trustees   and   officers  is  a 
director/trustee  or officer of each of the  investment  companies  in the 
Calvert  Group of Funds with the  exception of Calvert  Social  Investment 
Fund,  of which only Messrs.  Baird,  Guffey,  Silby and Sorrell are among 
the trustees,  Acacia Capital  Corporation,  of which only Messrs.  Blatz, 
Diehl,  Pugh and Sorrell are among the  directors,  Calvert  World  Values 
Fund,  Inc.,  of which only  Messrs.  Guffey,  Silby and Sorrell are among 
the  directors,  and Calvert New World Fund,  Inc.,  of which only Messrs. 
Sorrell  and  Martini are among the  directors.  The address of  directors 
and officers,  unless  otherwise noted, is 4550 Montgomery  Avenue,  Suite 
1000N,  Bethesda,  Maryland 20814.  Trustees and officers of the Fund as a 
group own less than 1% of the Fund's outstanding shares. 
         The Audit  Committee  of the Board is composed of Messrs.  Baird, 
Blatz,  Feldman,  Guffey and Pugh. The Board's Investment Policy Committee 
is composed of Messrs. Borts, Diehl, Gavian, Rochat, Silby and Sorrell. 
         During  fiscal  1995,  trustees of the Fund not  affiliated  with 
the Fund's  Advisor were paid $8,619.  Trustees of the Fund not affiliated 
with the  Advisor  presently  receive an annual fee of $20,250 for service 
as a member of the Board of Trustees of the  Calvert  Group of Funds,  and 
a fee of $750 to  $1200  for  each  regular  Board  or  Committee  meeting 
attended;  such  fees are  allocated  among  the  respective  Funds on the 
basis of net assets. 
         Trustees of the Fund not  affiliated  with the Fund's Advisor may 
elect to defer  receipt  of all or a  percentage  of their fees and invest 
them in any fund in the  Calvert  Family  of Funds  through  the  Trustees 
Deferred  Compensation  Plan  (shown as "Pension  or  Retirement  Benefits 
Accrued  as  part of  Fund  Expenses,"  below).  Deferral  of the  fees is 
designed  to  maintain  the  parties in the same  position  as if the fees 
were  paid on a  current  basis.  Management  believes  this  will  have a 
negligible effect on the Fund's assets,  liabilities,  net assets, and net 
income  per  share,  and  will  ensure  that  there is no  duplication  of 
advisory fees.

without  penalty by either  party on 60 days'  prior  written  notice;  it 
automatically terminates in the event of its assignment. 
         Under the  Contract,  the  Advisor  manages  the  investment  and 
reinvestment  of the Fund's  assets,  subject to the direction and control 
of the Fund's Board of Trustees.  For its services,  the Advisor  receives 
an annual  fee,  payable  monthly,  of 0.50% of the first $500  million of 
the Fund's  average  daily net assets,  0.475% of the next $500 million of 
such  assets,  0.45% of the next $500  million of such  assets,  0.425% of 
the next $500  million of such  assets,  and 0.40% of all such assets over 
$2 billion.  Until  September  30, 1993,  the Advisor  voluntarily  waived 
half of its  advisory  fee for the Fund,  and  charged  only  0.25% of the 
Fund's average daily net assets. 
         The Advisor  provides the Fund with  investment  supervision  and 
management,  administrative  services,  office space,  furnishes executive 
and other  personnel  to the Fund,  and pays the  salaries and fees of all 
Trustees  who are  affiliated  persons of the  Advisor.  The  Advisor  may 
assume and pay certain  Fund  advertising  and  promotional  expenses  and 
reserves  the  right to  compensate  broker-dealers  in  consideration  of 
their promotional or administrative services. 
         The Fund  pays all  other  expenses  including:  custodial  fees; 
shareholder  servicing,  dividend  disbursing  and  transfer  agency fees; 
federal  and  state  securities   registration  fees;   Distribution  Plan 
expenses;  insurance  premiums;  trade association dues;  interest,  taxes 
and other business fees;  legal and audit fees; and brokerage  commissions 
and other costs associated with the purchase and sale of Fund securities. 
         The  Advisor  has  agreed to  reimburse  the Fund for the  Fund's 
operating expenses (excluding  brokerage,  taxes,  interest,  Distribution 
Plan expenses and  extraordinary  items)  exceeding,  on a pro rata basis, 
the most  restrictive  state expense  limitation in those states where the 
Funds' shares are registered. 
         The advisory  fees paid for the 1993,  1994,and 1995 fiscal years 
were $296,175, $516,334, and $378,388,  respectively.  The advisor did not 
reimburse  the Fund during the 1993 or 1994  fiscal  years.  During  1995, 
the Advisor  voluntarily  waived fees or assumed expenses of $71,798 which 
were not charged to the Fund.

========================================================================== 
                  INDEPENDENT ACCOUNTANTS AND CUSTODIANS 
========================================================================== 

         Coopers  &  Lybrand,  L.L.P.  has been  selected  by the Board of 
Trustees to serve as  independent  auditors  for fiscal  year 1996.  State 
Street  Bank & Trust  Company,  N.A.,  225  Franklin  Street,  Boston,  MA 
02110,  serves as  custodian  of the Fund's  investments.  First  National 
Bank of Maryland,  25 South  Charles  Street,  Baltimore,  Maryland  21203 
also  serves as  custodian  of  certain  of the Fund's  cash  assets.  The 
custodian  has no part in deciding the Fund's  investment  policies or the 
choice  of  securities  that are to be  purchased  or sold for the  Fund's 
Funds. 

========================================================================== 
                          METHOD OF DISTRIBUTION 
========================================================================== 

         The  Fund   has   entered   into  an   agreement   with   Calvert 
Distributors,  Inc.  ("CDI") whereby CDI, acting as principal  underwriter 
for the Fund,  makes a continuous  offering of the Fund's  securities on a 
"best efforts" basis.  Under the terms of the agreements,  CDI is entitled 
to  receive,  pursuant to the Fund's  Distribution  Plan,  a  distribution 
service  fee  from the Fund of 0.35%  of its  average  daily  net  assets. 
Salespersons  may receive varying  compensation  depending on the class of 
shares they sell. 
         Pursuant  to Rule  12b-1  under  the  Investment  Company  Act of 
1940,  the Fund  has  adopted  a  Distribution  Plan  (the  "Plan")  which 
permits it to pay certain  expenses  associated  with the  distribution of 
shares.  Such expenses may not exceed,  on an annual  basis,  0.35% of the 
Fund's  average daily net assets.  The  Distribution  Plan was approved by 
shareholders  of the Fund  and by the  Board of  Trustees,  including  the 
Trustees  who are not  "interested  persons"  of the Fund (as that term is 
defined in the  Investment  Company Act of 1940) and who have no direct or 
indirect  financial  interest  in  the  operation  of the  Plan  or in any 
agreements  related  to the Plan.  The  selection  and  nomination  of the 
Trustees  who are not  interested  persons of the Fund is committed to the 
discretion of such disinterested  Trustees.  In establishing the Plan, the 
Trustees   considered   various  factors   including  the  amount  of  the 
distribution  fee (a maximum of 0.35%  annually of the Fund's  average net 
assets).  The Trustees  determined  that there is a reasonable  likelihood 
that the Plan will benefit the Fund and its shareholders. 
         The  Plan  may  be  terminated  by  vote  of a  majority  of  the 
non-interested  Trustees who have no direct or indirect financial interest 
in the Plan,  or by vote of a majority  of the  outstanding  shares of the 
Fund.  Any  change  in  the  Plan  that  would  materially   increase  the 
distribution cost to the Fund requires  shareholder  approval;  otherwise, 
the Plan may be  amended by the  Trustees,  including  a  majority  of the 
non-interested Trustees as described above. 
         The Plan will  continue in effect until  January 3, 1997,  if not 
sooner  terminated  in  accordance  with its terms.  Thereafter,  the Plan 
will  continue in effect for  successive  one year periods  provided  that 
such  continuance is  specifically  approved by (i) the vote of a majority 
of the Trustees who are not parties to the Plan or  interested  persons of 
any such party and who have no direct or  indirect  financial  interest in 
the  Plan,  and  (ii)  the  vote of a  majority  of the  entire  Board  of 
Trustees. 
         For the  1993,  1994,  and  1995  fiscal  years,  the  Fund  paid 
Distribution   Plan   expenses  of  $236,748,   $351,119,   and  $315,130, 
respectively.  Fiscal  year  1995  Distribution  Plan  expenses  were used 
entirely to compensate dealers  distributing  shares. Apart from the Plan, 
the Advisor  and the  principal  underwriter,  at their own  expense,  may 
incur costs and pay expenses  associated  with the  distribution of shares 
of the Fund. 

========================================================================== 
                          PORTFOLIO TRANSACTIONS 
========================================================================== 

         Transactions   are   allocated   to  various   underwriters   and 
broker-dealers  by  the  Fund's  Advisor.   Newly  issued  securities  are 
purchased from  underwriters  acting as principals at prices which include 
underwriting  fees.  Purchases of securities  in the secondary  market and 
all sales are placed  with  broker-dealers  who may be acting as agents or 
principals.  Broker-dealers  who execute  Fund  transactions  on behalf of 
the  Fund  are  selected   primarily  on  the  basis  of  their  execution 
capability  and  secondarily  on the value and quality of their  services. 
The Advisor may place orders for the  purchase or sale of Fund  securities 
with qualified  broker-dealers who provide it with statistical,  research, 
or  other  information  and  services.  Such  broker-dealers  may  receive 
compensation  for  executing  Fund  transactions  that is in excess of the 
compensation  another  broker-dealer  would have  received  for  executing 
such  transactions  if the  Advisor  determines  in good  faith  that such 
compensation  is  reasonable  in relation to the value of the  information 
or services that have been provided.  No brokerage  commissions  were paid 
by the Fund in the past three fiscal years. 
         The Advisor may also  execute Fund  transactions  with or through 
broker-dealers  who have  sold  shares of the Fund.  However,  such  sales 
will not be a  qualifying  or  disqualifying  factor in a  broker-dealer's 
selection  nor will the  selection  of any  broker-dealer  be based on the 
volume of Fund shares sold. 

========================================================================== 
                           GENERAL INFORMATION 
========================================================================== 

         The Fund is the only  series of a  Massachusetts  business  trust 
organized on March 16, 1982,  under the name  Calvert Cash  Reserves,  now 
doing business as Money Management  Plus. The Fund's  Declaration of Trust 
contains  an  express  disclaimer  of  shareholder  liability  for acts or 
obligations  of the Fund. The  shareholders  of a  Massachusetts  business 
trust might,  however,  under certain  circumstances,  be held  personally 
liable  as  partners  for  its  obligations.   The  Declaration  of  Trust 
provides for  indemnification  and  reimbursement  of expenses out of Fund 
assets for any shareholder  held personally  liable for obligations of the 
Fund.  The  Declaration  of  Trust  provides  that the  Fund  shall,  upon 
request,  assume the  defense of any claim made  against  any  shareholder 
for any act or  obligation  of the Fund and satisfy any judgment  thereon. 
The  Declaration  of Trust  further  provides  that the Fund may  maintain 
appropriate  insurance  (for  example,  fidelity  bonding  and  errors and 
omissions  insurance) for the  protection of the Fund,  its  shareholders, 
Trustees,  officers,  employees,  and  agents to cover  possible  tort and 
other  liabilities.  Thus, the risk of a shareholder  incurring  financial 
loss on account of shareholder  liability is limited to  circumstances  in 
which both  inadequate  insurance  exists and the Fund itself is unable to 
meet its obligations. 
         The Fund will send its  shareholders  unaudited  semi-annual  and 
audited  annual  reports  that will include the Fund's net asset value per 
share,  Fund  securities,   income  and  expenses,   and  other  financial 
information. 
         This  Statement of  Additional  Information  does not contain all 
the information in the Fund's  registration  statement.  The  registration 
statement is on file with the  Securities  and Exchange  Commission and is 
available to the public.

                           FINANCIAL STATEMENTS 
========================================================================== 

         The audited  financial  statements  included in the Annual Report 
to Shareholders  dated  September 30, 1995, are expressly  incorporated by 
reference  and made a part of this  Statement of  Additional  Information. 
Copies  of this  Report  may be  obtained  free of charge  by  writing  or

                                 APPENDIX 
========================================================================== 

Commercial Paper Ratings 
         Commercial  paper rated A-1 by Standard & Poor's  Corporation has 
the  following  characteristics:  liquidity  ratios are  adequate  to meet 
cash  requirements;  long-term  senior  debt is rated "A" or  better;  the 
issuer  has  access  to at least two  additional  channels  of  borrowing; 
basic  earnings  and cash flow have an upward  trend with  allowance  made 
for  unusual  circumstances;  typically,  the  issuer's  industry  is well 
established  and the issuer  has a strong  position  within the  industry; 
and the  reliability  and  quality of  management  are  unquestioned.  The 
relative strength or weakness of the above factors  determines  whether an 
issuer's commercial paper is rated Al, A2, or A3. 
         The  rating  Prime-1  is  the  highest  commercial  paper  rating 
assigned by Moody's Investors  Service,  Inc. Among the factors considered 
by  Moody's  in  assigning  rating are the  following:  evaluation  of the 
management of the issuer;  economic  evaluation  of the issuer's  industry 
or  industries  and an  appraisal of  speculative-type  risks which may be 
inherent  in  certain  areas;  evaluation  of  the  issuer's  products  in 
relation to competition  and customer  acceptance;  liquidity;  amount and 
quality of long-term  debt;  trend of earnings over a period of ten years; 
financial  strength of a parent company and the relationships  which exist 
with the issuer;  and  recognition by the management of obligations  which 
may be present or may arise as a result of public  interest  question  and 
preparations to meet such obligations.

Item 27.  Indemnification 

         Registrant's Declaration of Trust, which Declaration is Exhibit

trustees, employees, and agents shall be indemnified by Registrant  
against liabilities and expenses incurred by such persons in connection  
with actions, suits, or proceedings arising out of their offices or  
duties of employment, except that no indemnification can be made to such  
a person if he has been adjudged liable of willful misfeasance, bad  
faith, gross negligence, or reckless disregard of his duties.  In the  
absence of such an adjudication, the determination of eligibility for  
indemnification shall be made by independent counsel in a written  
opinion or by the vote of a majority of a quorum of trustees who are  
neither "interested persons" of Registrant, as that term is defined in  
Section 2(a)(19) of the Investment Company Act of 1940, nor parties to  
the proceeding. 

         Registrant's Declaration of Trust also provides that Registrant  
may purchase and maintain liability insurance on behalf of any officer,  
trustee, employee or agent against any liabilities arising from such  
status.  In this regard, Registrant maintains a Directors & Officers  
(Partners) Liability Insurance Policy with Chubb Group of Insurance  
Companies, 15 Mountain View Road, Warren, New Jersey  07061, providing

Ladies and Gentlemen: 

         As counsel to Calvert Cash Reserves (d/b/a Money  
Management Plus) (the "Trust"), it is my opinion, based upon an  
examination of the Trust's Declaration of Trust and By-Laws and  
such other original or photostatic copies of Trust records,  
certificates of public officials, documents, papers, statutes,  
and authorities as I deemed necessary to form the basis of this  
opinion, that the securities being registered by this  
Post-Effective Amendment No. 19 of the Trust will, when sold,  
be legally issued, fully paid and non-assessable. 

         Consent is hereby given to file this opinion of counsel  
with the Securities and Exchange Commission as an Exhibit to  
the Trust's Post-Effective Amendment No. 19 to its Registration  
Statement. 

                                                Sincerely,
